Japanese Patent Application Publication No. 11-141933

In the tabletop air purifier of Patent Document 1, air above the table is taken into the inside of the main body through the intake port by driving an electric fan, and dust and fine particles are removed from the taken-in air in the dust collection section. Next, the air that passes through the dust collection section is subjected to a photocatalytic filter to inactivate bacteria and viruses and to a deodorizing process for odors (hereinafter referred to as sterilization and deodorization process), and the air after sterilization and deodorization is discharged to the outside of the main body through an exhaust port provided near the floor surface of the main body. However, in the tabletop air purifier of Patent Document 1, sterilization and deodorization process is performed on the air taken into the inside of the main body, and further, the air after sterilization and deodorization process is discharged to the feet. Therefore, the amount of viruses and odors in the space around the upper body of a seated user is not reduced unless they are taken into the inside of the main body, which means that there is room for improvement in that the sterilization and deodorization process is not quick-acting.

The present invention aims to provide a sterilization and deodorization device that is applied to a table or chair and can quickly and effectively perform sterilization and deodorization treatment on the air around the upper body of a seated user.

The sterilization and deodorization device of the present invention comprises an ozone generating unit 12 that generates ozone, a supplying means 13 that supplies ozone on air, an ozone blowing unit 14 that blows out air containing ozone, and a control unit 15 that controls the operation of the ozone generating unit 12 and the supplying means 13, and is configured so that at least the ozone blowing unit 14 is provided on the top plate 4 of the desk 2 or the seat 8 of the chair 3. In this way, ozone can be directly supplied to the periphery of the top plate 4 of the desk 2 or the seat 8 of the chair 3 on which the ozone blowing unit 14 is provided, and the ozone can be used to inactivate viruses and the like and to deodorize odors. Therefore, sterilization and deodorization can be performed quickly and effectively on the air around the upper body of a seated user.

The ozone blowing section 14 has a group of blowing ports 28 that blow air containing ozone upward. When the group of blowing ports 28 are arranged in a row, an air curtain can be formed that extends upward from the ozone blowing section 14. For example, by arranging the ozone blowing section 14 between people who are sitting next to each other or facing each other during a conversation or meal, it is possible to perform sterilization and deodorization treatment on the surrounding air while providing an invisible partition with an air curtain.

The ozone blowing section 14 is provided on the upper surface of the tabletop 4 of the desk 2, and a group of blowing ports 28 can be arranged across the center of the upper surface of the tabletop 4. In this way, when the ozone blowing ports 28 are arranged across the center of the upper surface of the tabletop 4, it is possible to perform sterilization and deodorization treatment on the air above the two-seater or four-seater desk 2 while providing an invisible partition made of an air curtain above the desk 2.

The ozone blowing section 14 is provided on the seat plate 6 or backrest 7 of the chair 3, and a group of blowing outlets 28 can be arranged along at least one of the back edge, left edge, right edge of the seat plate 6, and the upper edge of the backrest 7. In this way, when the ozone blowing outlets 28 are arranged along at least one of the back edge, left edge, right edge of the seat plate 6, and the upper edge of the backrest 7, it is possible to perform sterilization and deodorization treatment on the air above the chair 3 while providing an invisible partition made of an air curtain on the back and/or left and right sides except for the front of the chair 3.

The group of air outlets 28 are arranged in a linear row, and the air blown out from the group of air outlets 28 is configured to form a fan-shaped air flow that expands in the direction of the row as it moves upward. This allows the formation of an air curtain with a length greater than the formation length of the ozone blowing section 14, so that even a compact ozone blowing section 14 can provide a large invisible partition. In addition, sterilization and deodorization treatment can be performed over a wide area.

If the wind pressure of the air blown out from each outlet 28 is set to increase from the center of the group of outlets 28 toward each end, the air blown out from the end of the ozone blowing section 14 can be sent higher, forming the end part of the air curtain at the same height as the center part.

The ozone blowing unit 14 includes a blowing unit body 48 installed on the top surface of the tabletop 4 of the desk 2, and a group of blowing ports 28 provided in the blowing unit body 48 for blowing out air containing ozone. The blowing unit body 48 can be configured to be installed in either an upward blowing position in which air is blown upward from the group of blowing ports 28, or a lateral blowing position in which air is blown sideways from the group of blowing ports 28. With this, when the blowing unit body 48 is in the upward blowing position, air containing ozone can be delivered toward the top of the desk 2. Therefore, when a person is having a conversation or eating face-to-face, the blowing unit body 48 can be in the upward blowing position to provide an invisible partition between the person facing the person, and the air above the desk 2 can be sterilized and deodorized. In addition, when the blower body 48 is in a horizontal blowing position, air containing ozone can be sent toward the side of the desk 2. Therefore, when people are talking or eating next to each other, the blower body 48 can be in a horizontal blowing position to provide an invisible partition between the people next to each other, and the air on the side of the desk 2 can be sterilized and deodorized.

A seating detection means 40 is provided for each of the multiple seating positions, which detects that a user has sat down and sends a seating signal to the control unit 15. When two or more seating detection means 40 detect that a user has sat down, the control unit 15 can be configured to drive the ozone generation unit 12 and the supply means 13. In this way, when multiple users are seated, air containing ozone is blown out from the ozone blowing unit 14, so that sterilization and deodorization treatment can be automatically performed on the surrounding air while providing an invisible partition between users. When only one user is seated, no air partition is required, so power consumption can be reduced by stopping the operation of the ozone generation unit 12 and the supply means 13.

The ozone blowing section 14 is provided on the top plate 4 of the desk 2, and a group of blowing ports 28 can be arranged on the four periphery of the upper surface of the top plate 4. In this way, the ozone blowing section 14 arranged to surround the periphery of the upper surface of the top plate 4 allows the upper surface of the top plate 4 to be widely used, and it is possible to avoid the usability of the desk 2 being reduced due to the provision of the ozone blowing section 14.

The ozone blowing unit 14 comprises a blowing unit main body 48 installed in the center of the top surface of the desk 2, and a blowing nozzle 50 provided on the blowing unit main body 48 for blowing out air containing ozone, and the blowing nozzle 50 can be arranged so as to deliver air towards a seated user. In this way, when the blowing nozzle 50 is arranged so as to deliver air towards a seated user, ozone having a sterilizing and deodorizing function can be directly delivered to the user, and the ozone can be used to inactivate viruses and the like and to deodorize odors.

The blowing nozzle 50 can be made to supply air in a radial direction relative to the central axis of the blowing unit main body 48 in the vertical direction. This allows ozone to be directly supplied in the radial direction starting from the center of the top surface of the desk 2, and the ozone can be used to inactivate viruses and deodorize odors. In addition, even if multiple people are seated at the desk 2, air containing ozone can be supplied to all of them.

When the blow-out nozzle 50 is supported on the blow-out unit main body 48 so that it can be adjusted up and down, the direction of the blow-out nozzle 50 can be adjusted to send air containing ozone in the direction desired by the user, and sterilization and deodorization treatment can be performed on the air in the direction of the air being sent. For example, if a user dislikes air being sent towards their face, the blow-out nozzle 50 can be directed towards the head or chest to prevent air from hitting their face. Air can be sent towards the face according to the user's physique.

The blowing unit main body 48 is provided with multiple blowing nozzles 50, and the blowing nozzles 50 are provided with nozzle holes 49 that blow out air containing ozone and a nozzle opening/closing means 62 that opens and closes the nozzle holes 49. By blocking the nozzle holes 49 that are directed in a direction where sterilization and deodorization treatment is not required with the nozzle opening/closing means 62, the amount of ozone-containing air blown out from the other nozzle holes 49 can be increased, so that a larger amount of ozone-containing air can be sent in the required direction to perform sterilization and deodorization treatment more quickly and effectively.

The ozone generating unit 12, the supply means 13, and the control unit 15 are housed in a casing 110, and an ozone blowing unit 14 is disposed at the upper end of the casing 110. The casing 110 is formed as a portable unit that can be separated from the desk 2 or the chair 3, and can be configured to be hung from the neck by a hanging device 111. In this way, by hanging the casing 110 from the neck as necessary, the air around the face can be sterilized and deodorized.

The casing 110 comprises a main body 117 suspended by a suspender 111, and a head 118 supported so as to be tiltable back and forth relative to the main body 117. When the ozone blowing section 14 is provided on the upper surface of the head 118, the direction of air blown out from the ozone blowing section 14 can be adjusted by tilting the head 118, so that air containing ozone can be blown to any position on the user's face regardless of the position of the main body 117 held by the suspender 111. For example, it is possible to blow air to the face or to a position away from the face.

When the vertical extension direction of the main body 117 is aligned with the vertical axis, the head 118 is supported displaceably with respect to the main body 117 between an upright position in which the blowing direction of the ozone blowing unit 14 is aligned with the vertical axis in a side view and a forward-leaning position in which the blowing direction of the ozone blowing unit 14 is inclined forward with respect to the vertical axis, and is provided with a position detector 120 that detects when the head 118 is in a forward-leaning position. When the position detector 120 is on, the control unit 15 drives the ozone generating unit 12, and when the position detector 120 is off, the control unit 15 can be configured to stop the ozone generating unit 12. According to this, when the head 118 is in an upright position, that is, when the air supply direction is close to the face and a lot of air touches the face, the ozone generating unit 12 is stopped, and the user can be given a feeling of coolness without feeling the unique odor of ozone. In addition, when the head unit 118 is in a forward-leaning position, i.e., when the air supply direction is away from the face and more air is supplied in front of the face, the ozone generator 12 can be driven to perform sterilization and deodorization processing on the air in front of the face.

The ozone blowing unit 14 is provided on the top plate 4 of the desk 2, and is provided with a display unit 134 that displays various information, a seating detection means 40 that detects that a user has sat down in front of the display unit 134 and transmits a seating signal to the control unit 15, and/or a start-up switch 135 that transmits a start-up signal to the control unit 15 to start the display unit 134. When the control unit 15 receives a seating signal or a start-up signal, it can be configured to execute a start-up step that starts driving the ozone generating unit 12, the feeding means 13, and the display unit 134. In this way, when the user operates the start-up switch 135 to view information on the display unit 134 or sits down in front of the display unit 134, the sterilization and deodorization process can be started on the surrounding air. In addition, if the control unit 15 is configured to execute a display step that displays an operation display on the display unit 134 that air containing ozone is being blown out from the ozone blowing unit 14, the user can be made aware that the sterilization and deodorization process is being performed.

The system includes a communication unit 136 that can be connected to a store terminal 137 equipped with an order reception system installed in the store, and the display unit 134 includes a touch panel type input means 133. The control unit 15 can be configured to execute an order reception step of displaying menu data acquired from the store terminal 137 via the communication unit 136 on the display unit 134 and receiving an order from the user, and an order transmission step of transmitting an order selected by the user to the store terminal 137, following the display step. This allows the user to purchase products from the store while remaining seated at a desk 2 installed in the store, thereby improving user convenience.

The communication unit 136 is configured to be connectable to the Internet, and the control unit 15 can be configured to transition to a viewing step in which information acquired from the Internet via the communication unit 136 can be viewed on the display unit 134 when the order transmission step is completed or the order reception step is skipped. This allows the user to view information while waiting to receive a product purchased at the store, while eating and drinking, or while waiting for a short period of time at the store, allowing the user to spend each of these times productively.

The control unit 15 is configured to stop driving the display unit 134 when a predetermined cut-off time T has elapsed after transitioning to the viewing step, and a form can be adopted in which the cut-off time TS when skipping the order receiving step and transitioning to the viewing step is set to be shorter than the cut-off time TL when the order sending step is completed and transitioning to the viewing step is made. In this way, when a product is purchased, information can be viewed for a longer period of time, which encourages the user to purchase the product. Furthermore, by setting the cut-off time T, it is possible to prevent the user from using the desk 2 for long periods of time.

The control unit 15 is configured to stop driving the ozone generating unit 12 and the supplying means 13 when a preset drive stop time has elapsed after the shutoff time T has elapsed. This automatically stops driving the ozone generating unit 12 and the supplying means 13, making it possible to avoid unnecessary power consumption.

(Example 1) Figures 1 to 3 show Example 1 in which the sterilization and deodorization device according to the present invention is applied to a desk. In this example, the front, back, left, right, and up and down refer to the crossed arrows shown in Figure 1 and the indications of front, back, left, right, and up and down written near each arrow. Note that a desk means a table on which objects are placed or on which reading and writing are performed, such as a dining table installed in a home or store, a long desk installed in a library, or a workbench installed in an office or factory, supported by legs. In Figure 1, the sterilization and deodorization device 1 is integrally configured with a table 2 of a table set consisting of a table (desk) 2 as a dining table and four chairs 3. The table 2 is configured with a top plate (base) 4 that is horizontally elongated in a plan view and four table legs (legs) 5 that extend downward from the four corners of the bottom surface of the top plate 4, and is configured so that two people can sit side by side on the front and rear sides. The chair 3 is composed of a seat panel 6 that is square in shape with rounded corners in a plan view, a seat section 8 that includes a backrest 7 that faces upward from the rear edge of the upper surface of the seat panel 6, and four chair legs 9 that extend downward from the four corners of the lower surface of the seat panel 6. The chair 3 may also be equipped with armrests, in which case the armrests form the seat section 8.

In FIG. 2, the sterilization and deodorization device 1 includes an ozone generating unit 12 that generates ozone, a supplying means 13 that supplies the ozone generated by the ozone generating unit 12 on air, an ozone blowing unit 14 that blows out air containing the ozone supplied by the supplying means 13, and a control unit 15 (see FIG. 3) that controls the operation of the ozone generating unit 12 and the supplying means 13, etc., and of these, the ozone generating unit 12, the supplying means 13, and the control unit 15 are built into a housing 18. The sterilization and deodorization device 1 receives driving power from a commercial power source.

The housing 18 is formed in a horizontally long rectangular box shape and is fixed to the back surface of the top plate 4. An air flow path 19 is provided inside the housing 18. The air flow path 19 is an inverted T-shaped flow path in front view, consisting of a horizontal flow path 20 extending in the left-right direction and a vertical flow path 21 extending in the up-down direction. Both ends of the horizontal flow path 20 are connected to air intake ports 22 opening in the left and right side walls of the housing 18, respectively, and the upper end of the vertical flow path 21 is connected to an air supply port 23 opening in the upper wall of the housing 18. Each air intake port 22 is provided with a filter 24 that prevents foreign matter from entering the air flow path 19.

The ozone generating unit 12 and the supplying means 13 are installed in the air flow path 19. Specifically, the ozone generating unit 12 is installed at the intersection of the horizontal flow path 20 and the vertical flow path 21, and the supplying means 13 is provided near the left and right ends of the horizontal flow path 20. The supplying means 13 can be configured as an axial flow type blower consisting of a propeller fan and a fan motor that drives the fan to rotate, or a centrifugal type blower consisting of a centrifugal fan and a fan motor that drives the fan to rotate.

The ozone blowing unit 14 is installed on the top plate 4 and includes a blowing base 27 that is embedded and fixed in the top plate 4, and a group of blowing ports 28 that open on the top surface of the blowing base 27. Each blowing port 28 is composed of a round hole with the same opening diameter. The blowing base 27 is formed in a cross block shape that is thinner than the top plate 4, and two groups of blowing ports 28 are provided in a linear row (row) extending forward and backward and a linear row (row) extending left and right along the shape of the blowing base 27. The intersection of the blowing base 27 is arranged in the center of the top plate 4, and the groups of blowing ports 28 arranged in two linear rows each cross the center of the top plate 4. Thus, the ozone blowing unit 14 is arranged to divide the top surface of the top plate 4 into four. The top surface of the top plate 4 and the top surface of the blowing base 27 are flush with each other. The group of air outlets 28 may be arranged in a row, such as a wave, arc, or broken line, and the row is not limited to a straight line. Also, each air outlet 28 may be an elliptical or polygonal hole other than a round hole.

When the blow-out port 28 at the supply port 30 is used as a reference, each blow-out port 28 can be configured so that its opening diameter gradually increases the further away from the supply port 30. If each blow-out port 28 were configured as a round hole with the same opening diameter, there is a risk that a larger amount of ozone-containing air will be blown out from the blow-out port 28 located closer to the supply port 30, but with this configuration, it is possible to blow out ozone-containing air almost evenly from each blow-out port 28.

A cross-shaped communication groove 29 is recessed into the underside of the blow-out base 27, and each blow-out port 28 is connected to the communication groove 29. The communication groove 29 faces a supply port 30 that opens into the underside of the top plate 4, and the vertical flow path 21 and the communication groove 29 are connected via the supply port 30. Air supplied through the air flow path 19 is blown upward from each blow-out port 28 via the supply port 30 and the communication groove 29.

As shown in FIG. 3, the ozone generating unit 12 is composed of a needle-shaped discharge electrode 33, a crown-shaped counter electrode 34 arranged to face the discharge electrode 33, and a drive unit 35 that applies a voltage between the electrodes 33 and 34 to generate ozone. The drive unit 35 is composed of a rectifier circuit 36 that rectifies the AC current of a commercial power source to obtain a DC current, a pulse generating circuit 37 that converts the DC current input from the rectifier circuit 36 into a pulse current, a boost circuit 38 including a transformer that increases the voltage of the pulse current, and a diode 39 that is provided between the boost circuit 38 and the discharge electrode 33. Ozone is generated by generating a corona discharge between the electrodes 33 and 34 to which a high voltage is applied. Although the ozone generating unit 12 employs a corona discharge method, other ozone generating devices such as an ultraviolet ray method, a low-temperature plasma method, or an electrolysis method may also be used.

As shown in FIG. 1, the front and rear surfaces of the tabletop 4 are provided with seating detection means 40 that detect a user seated on the chair 3 corresponding to the seating position (the position where the chair 3 is arranged). The seating detection means 40 can be configured with a heat detection sensor using infrared rays, or a distance measurement sensor using infrared rays or microwaves. Of these, the distance measurement sensor may detect the backrest 7 erroneously, so it is preferable that the seating detection means 40 is configured with a heat detection sensor. When the seating detection means 40 detects a user (the user is seated), it outputs an ON signal to the control unit 15, and when the seating detection means 40 does not detect a user (the user is not seated), it outputs an OFF signal to the control unit 15. Of course, the output of the OFF signal and the ON signal of the seating detection means 40 may be reversed. The seating detection means 40 may also be configured with a pressure switch that detects that an object has been placed on the tabletop 4.

When the control unit 15 receives an on signal from two or more seating detection means 40, it activates the ozone generating unit 12 and the supplying means 13. When these devices (ozone generating unit 12, supplying means 13) start to operate, air under the tabletop 4 is taken in from the air intake 22 into the air flow path 19, and the taken in air is sent to the air outlet 23 together with ozone released from the ozone generating unit 12. The ozone-containing air that reaches the air outlet 23 is sent to the communication groove 29 via the supply port 30 and blown upward from each blowing port 28. The air blown out from the blowing port 28 performs sterilization and deodorization treatment on the air above the tabletop 4. In addition, the air blown out from the blowing port 28 forms a cross-shaped air curtain above the tabletop 4, so that an invisible partition by the air curtain can be provided between seated users.

As described above, in the sterilization and deodorization device 1 of this embodiment, the ozone blowing section 14 is provided on the top plate 4 of the table 2, so that ozone can be directly supplied to the periphery of the top plate 4 of the table 2 on which the ozone blowing section 14 is provided, and the ozone can be used to inactivate viruses and the like and to deodorize odors. Therefore, sterilization and deodorization can be performed quickly and effectively on the air around the upper body of a seated user.

The ozone blowing unit 14 has a group of blowing ports 28 arranged in a row that blows out air containing ozone upward, so that an air curtain can be formed that extends upward from the ozone blowing unit 14. For example, by arranging the ozone blowing unit 14 between people who are sitting next to each other or facing each other during a conversation or meal, it is possible to perform sterilization and deodorization treatment on the surrounding air while providing an invisible partition with an air curtain.

The ozone blowing section 14 is provided on the upper surface of the top plate 4 of the table 2, and a group of blowing ports 28 are arranged across the center of the upper surface of the top plate 4, so that the air above the two-seater or four-seater table 2 can be disinfected and deodorized while providing an invisible partition made of an air curtain above the table 2.

A seating detection means 40 is provided for each of the multiple seating positions, which detects when a user has sat down and sends a seating signal to the control unit 15, and when two or more seating detection means 40 detect that a user has sat down, the control unit 15 drives the ozone generation unit 12 and the supply means 13. With this, when multiple users are seated, air containing ozone is blown out from the ozone blowing unit 14, so that it is possible to automatically sterilize and deodorize the surrounding air while providing an invisible partition between users. When only one user is seated, no air partition is required, so power consumption can be reduced by stopping the operation of the ozone generation unit 12 and the supply means 13.

(Example 2) Figures 4 and 5 show Example 2 in which the sterilization and deodorization device according to the present invention is applied to a desk, and the installation form of the ozone blowing unit 14 is different from Example 1. In addition, the table 2 has a top plate 4 formed in a square shape in a plan view, and is shaped so that one person can sit on each side. In this example, the ozone blowing unit 14 is arranged on the four peripheral edges of the upper surface of the top plate 4. The blowing base 27 is formed in a square frame shape slightly smaller than the outer shape of the top plate 4, and a group of four rows of blowing ports 28 are provided along the blowing base 27. In order to connect the housing 18 and the ozone blowing unit 14, a distributor 44 is arranged between the top plate 4 and the housing 18, which branches the air supplied to the air supply port 23 by the supply means 13 into four branch flow paths 43 in the front, back, left and right directions, and the downstream end of each branch flow path 43 is connected to the supply port 30 by a connection pipe 45. The seating detection means 40 are provided on the front, back, left and right surfaces of the tabletop 4. Other points are the same as in Example 1, so the same configurations, structures and members are given the same reference numerals and their explanations are omitted. The same applies to each of the following examples.

As described above, in the sterilization and deodorization device 1 of this embodiment, a group of air outlets 28 is arranged on the four edges of the upper surface of the tabletop 4, so that the upper surface of the tabletop 4 can be widely used, and the provision of the ozone outlet section 14 can be used to avoid the table 2 becoming less user-friendly.

(Example 3) Figure 6 shows Example 3 in which the sterilization and deodorization device according to the present invention is applied to a chair. In this example, the sterilization and deodorization device 1 is integrated with the chair, and a housing 18 in which the ozone generating unit 12, the supply means 13, the control unit 15, etc. are built is fixed to the back surface of the seat plate 6. The ozone blowing unit 14 is arranged along the left and right edges and the rear edge (back edge) of the upper surface of the seat plate 6. The blowing base 27 is formed in a U-shaped frame shape that is slightly smaller than the outer shape of the seat plate 6, and a group of three rows of blowing ports 28 is provided along the blowing base 27. In this example, as in Example 2, a distributor 44 and a connection pipe 45 are arranged between the top plate 4 and the housing 18. A seating detection means 40 is provided on the surface of the backrest 7 that receives the back of the person, and in this example, when an ON signal is received from the seating detection means 40, the ozone generating unit 12 and the supply means 13 are activated. The seating detection means 40 can also be configured as a pressure switch that detects when someone sits on the seat plate 6. In addition, a plurality of chairs 3 to which the sterilization and deodorization device 1 is applied can be prepared so that these chairs 3 can operate in conjunction with each other. In this case, as in Example 1, the control unit 15 can be configured to start the ozone generation unit 12 and the supplying means 13 when an ON signal is output from the seating detection means 40 of two or more of the linked chairs 3.

As described above, in the sterilization and deodorization device 1 of this embodiment, the ozone blowing section 14 is provided on the seat plate 6 of the chair 3, so that ozone can be directly supplied to the periphery of the seat plate 6 of the chair 3 on which the ozone blowing section 14 is provided, and the ozone can be used to inactivate viruses and the like and to deodorize odors. Therefore, sterilization and deodorization can be performed quickly and effectively on the air around the upper body of a seated user.

The ozone blowing section 14 is provided on the seat plate 6 of the chair 3, and a group of blowing ports 28 are arranged along the back edge, left edge, and right edge of the seat plate 6, so that the air above the chair 3 can be sterilized and deodorized while providing invisible partitions of air curtains on the back and left and right sides of the chair 3 except for the front.

(Example 4) Figures 7 to 9 show Example 4 in which the sterilization and deodorization device according to the present invention is applied to a desk. In this example, the ozone blowing section 14 is provided with a blowing section main body 48 and a blowing nozzle 50 having a nozzle hole 49 provided in the blowing section main body 48 and blowing out air containing ozone, and the sterilization and deodorization device 1 is configured by incorporating the ozone generating section 12, the supply means 13, the ozone blowing section 14, the control section 15, etc. in the blowing section main body 48. In addition, the sterilization and deodorization device 1 is fixed to the center of the upper surface of the tabletop 4. Specifically, as shown in Figure 8, the blowing section main body 48 is formed in a hollow dome shape by a hemispherical shell wall 51 constituting the upper half and a bottomed cylindrical wall 52 constituting the lower half, and the inside is divided into an upper chamber 54 and a lower chamber 55 by a partition wall 53. The air flow path 19 is composed of the upper chamber 54 and the lower chamber 55, and four air intakes 22 are provided at equal intervals in the cylindrical wall portion of the bottomed cylindrical wall 52. The ozone generating unit 12 and the supplying means 13 are provided in the center of the partition wall 53, and are installed in a stepped communication cylinder portion 56 that communicates between the upper chamber 54 and the lower chamber 55.

In FIG. 7, two blow-out nozzles 50 are provided on each of the front, rear, left and right parts of the upper hemispherical shell wall 51 of the blow-out unit main body 48, and are supported so as to be tiltable (adjustable) relative to the blow-out unit main body 48. As shown in FIG. 8, each blow-out nozzle 50 is integrally formed with a spherical axis 58 that is tiltably supported by a spherical shell-shaped socket 57 formed in the hemispherical shell wall 51, and a cylindrical nozzle axis 59, and a nozzle hole 49 is formed so as to penetrate the spherical axis 58 and the nozzle axis 59. By tilting the nozzle axis 59, the blow-out nozzle 50 can be oriented in any direction, front, rear, left and right, based on the center of the spherical axis 58. By adjusting the orientation of the nozzle axis 59, for example, toward a seated user, air can be supplied toward the user.

The blowing nozzle 50 is provided with a nozzle opening/closing means 62 for opening and closing the nozzle hole 49. As shown in FIG. 9, the nozzle opening/closing means 62 is provided with a nozzle inner wall 64 provided with a ventilation opening 63 in the middle of the nozzle hole 49, an opening/closing wing 65 that rotates between a closed position (position indicated by a two-dot chain line in FIG. 9) that covers the ventilation opening 63 and an open position (position indicated by a solid line in FIG. 9) that retreats from above the ventilation opening 63, and an operation knob 66 for rotating the opening/closing wing 65. The ventilation opening 63 is formed in a quadrant ring shape, and two ventilation openings 63 are provided in point symmetry with the center of the nozzle inner wall 64 as the symmetrical point. The opening/closing wing 65 is formed in a quadrant shape, and two opening/closing wings 65 are provided in point symmetry with the center of the nozzle inner wall 64 as the symmetrical point, and both opening/closing wings 65 are formed integrally with the operation knob 66. The operation knob 66 is supported rotatably in the center of the nozzle inner wall 64. By rotating the control knob 66 to change the amount of overlap of the opening and closing wings 65 over the ventilation opening 63, the amount of air passing through the ventilation opening 63 can be adjusted, and the amount of air blown out of the nozzle hole 49 can be varied. By blocking the ventilation opening 63 with the opening and closing wings 65 (setting the opening and closing wings 65 to the blocking position), air can be stopped from being blown out of the nozzle hole 49.

A power button 67 is provided on the top of the blowing unit main body 48, and when the power button 67 is pressed while the sterilization and deodorization device 1 is stopped, the control unit 15 starts the ozone generation unit 12 and the supply means 13. Conversely, when the power button 67 is pressed while the sterilization and deodorization device 1 is running, the control unit 15 stops the ozone generation unit 12 and the supply means 13.

As described above, in the sterilization and deodorization device 1 of this embodiment, the ozone blowing section 14 includes a blowing section main body 48 installed in the center of the top surface of the table 2, and a blowing nozzle 50 provided on the blowing section main body 48 for blowing out air containing ozone, and the blowing nozzle 50 is arranged so as to deliver air toward a seated user. In this way, ozone having a sterilization and deodorization function can be directly delivered to the user, and the ozone can be used to inactivate viruses and the like, and deodorize odors.

The blow-out nozzle 50 is supported on the blow-out unit main body 48 so that it can be adjusted up and down, so that by adjusting the direction of the blow-out nozzle 50, air containing ozone can be sent in the direction desired by the user, and sterilization and deodorization treatment can be performed on the air in the direction of the air being sent. For example, a user who does not like air being sent towards their face can point the blow-out nozzle 50 towards the top of their head or towards their chest to prevent air from hitting their face. Air can be sent towards the face according to the user's physique.

The blowing unit main body 48 is provided with multiple blowing nozzles 50, and the blowing nozzles 50 are configured to include nozzle holes 49 that blow out air containing ozone and a nozzle opening/closing means 62 that opens and closes the nozzle holes 49. Therefore, by blocking the nozzle holes 49 that are directed in a direction where sterilization and deodorization treatment is not required with the nozzle opening/closing means 62, the amount of air containing ozone blown out from the other nozzle holes 49 can be increased, and a larger amount of air containing ozone can be sent in the required direction to perform sterilization and deodorization treatment more quickly and effectively.

(Example 5) Figures 10 and 11 show Example 5 in which the sterilization and deodorization device according to the present invention is applied to a desk, and the configuration of the blowing unit body 48 and the blowing nozzle 50 is different from Example 4. The semispherical shell wall 51 of the blowing unit body 48 is divided into an upper spherical crown wall 70 and a lower spherical zone wall 71. A gap 72 is formed between the lower end edge of the spherical crown wall 70 and the upper end edge of the spherical zone wall 71, and in this example, the gap 72 corresponds to the blowing nozzle 50. The upper ends of the communicating tube part 56 and the spherical zone wall 71 are connected by a circular ring-shaped top wall 73. The area surrounded by the spherical crown wall 70 and the top wall 73 is configured as the upper chamber 54, and the air flow path 19 is configured by the upper chamber 54, the lower chamber 55, and the communicating tube part 56 that communicates between the two chambers 54 and 55.

A bearing block 75 supported by four ribs 74 is provided at the upper end of the communicating tube 56. A rotating shaft 76 protrudes downward from the center of the lower surface of the spherical crown wall 70, and the lower end of the rotating shaft 76 is supported by a bearing 77 fixed to the bearing block 75. Eight flat air-receiving pieces 78 are equally spaced and extend downward from the lower surface of the spherical crown wall 70. The central axis defined by the extension direction of the air-receiving pieces 78 in a plan view coincides with the tangent direction of the communicating tube 56. The power button 67 is installed on the front peripheral surface of the blowing unit main body 48.

When the power button 67 is pressed to start the ozone generating unit 12 and the supply means 13, air containing ozone is supplied to the upper chamber 54 through the ribs 74 at the upper end of the communicating tube 56. The air supplied to the upper chamber 54 is redirected outward by the inner surface of the spherical crown wall 70, and the air is supplied from the gap 72 (blowout nozzle 50) in a radial direction relative to the central axis of the blowout unit main body 48 in the vertical direction. At this time, the air redirected outward by the spherical crown wall 70 hits the wind-receiving piece 78, which rotates the spherical crown wall 70 supported by the rotating shaft 76, so that the air blown out from the gap 72 is evenly supplied in the circumferential direction. In the plan view shown in FIG. 11, the outer end of each wind-receiving piece 78 is positioned clockwise relative to the inner end with respect to the axis passing through the center of the spherical crown wall 70, so that the spherical crown wall 70 rotates counterclockwise.

As described above, in the sterilization and deodorization device 1 of this embodiment, the blowing nozzle 50 is configured to deliver air in a radial direction relative to the central axis of the blowing unit main body 48 in the vertical direction, so that ozone can be delivered directly in that radial direction starting from the center of the top surface of the table 2, inactivating viruses and the like with the ozone and deodorizing odors. Also, even if multiple people are seated at the table 2, air containing ozone can be delivered to all of them.

In the above embodiment, the air receiving piece 78 is used to supply air evenly in the circumferential direction, but it is also possible to omit the air receiving piece 78 and provide the communicating tube 56 with a structure that generates a swirling flow in the air being supplied to the communicating tube 56. This makes it possible to generate a flow that is inclined in the radial direction in the air being supplied to the upper chamber 54 from between the ribs 74 at the upper end of the communicating tube 56, so that the air blown out from the gap 72 (blowout nozzle 50) can be supplied evenly in the circumferential direction.

(Example 6) Figure 12 shows Example 6 of the sterilization and deodorization device according to the present invention, which differs from the above-mentioned examples in that the ozone generating section 12 and the supplying means 13 are provided as an external unit 81 separately from the table 2 or chair 3, i.e., only the ozone blowing section 14 constituting the sterilization and deodorization device 1 is provided on the table 2 or chair 3. In this example, the direction in which the tables 2 are arranged is defined as the left-right direction. The external unit 81 has a square box-shaped case body 82, in which the ozone generating section 12, the supplying means 13, the control section 15, etc. are built. An intake port 22 is provided on the right edge of the top surface of the case body 82, and a unit outlet 83 is provided on the left edge.

The external unit 81 supplies air containing ozone to the ozone blowing sections 14 provided on each of the two tables 2 and to the ozone blowing sections 14 provided on the armrests (seats 8) of the three adjacent sofas (chairs) 3. The ozone blowing sections 14 on the tables 2 have the same configuration as in Example 1, and the ozone blowing section 14 between the sofas 3 has a group of blowing ports 28 formed on the upper wall of a hollow box body. The external unit 81 and the ozone blowing section 14 are connected via a main pipe 84 and a sub-pipe 85 that branches off from the main pipe 84. The main pipe 84 and the sub-pipe 85 are installed under the floor and are pulled out onto the floor near the external unit 81, the tables 2, and the sofas 3.

Inside the case body 82, an air flow path 19 is formed from the air intake 22 to the upstream end of the main piping 84, and the ozone generating unit 12 and the supply means 13 are installed in the air flow path 19. Inside the case body 82, the air flow path 19 is branched and connected to the unit outlet 83. When the ozone generating unit 12 and the supply means 13 are driven, air above the external unit 81 is taken into the air flow path 19 from the air intake 22, and the taken-in air is sent to the main piping 84 together with ozone released from the ozone generating unit 12. The air containing ozone sent through the main piping 84 is sent to the ozone blowing unit 14 via the sub-piping 85 and blown out from a group of blowing outlets 28. In addition, a part of the air containing ozone is blown out from the unit outlet 83. The air blown out upward from the ozone blowing unit 14 between the sofas 3 forms an invisible partition consisting of an air curtain between adjacent sofas 3.

As in the above embodiment, the ozone generating unit 12, the supplying means 13, and the control unit 15 constituting the sterilization and deodorization device 1 can be provided separately from the table 2 and the chair 3, and it is sufficient that at least the ozone blowing unit 14 is provided on the table 2 and the chair 3.

(Example 7) Figures 13 to 15 show Example 7 of the sterilization and deodorization device according to the present invention. In this example, the ozone blowing section 14 is provided with a hollow box-shaped blowing section main body 48 and a group of blowing ports 28 provided in the blowing section main body 48, and the sterilization and deodorization device 1 is configured by incorporating the ozone generating section 12, the feeding means 13, the ozone blowing section 14, the control section 15, etc. in the blowing section main body 48. The sterilization and deodorization device 1 is a stationary type that is placed on the top plate 4 of the table 2, and can be placed at any position on the top plate 4. As shown in Figure 13, the blowing section main body 48 is formed in a square box shape, and a group of blowing ports 28 are provided on its upper wall, and an intake port 22 with a filter 24 arranged therein is provided on the right side wall. The blowing unit body 48 is configured to be able to be placed on the top surface of the tabletop 4 in either an upward blowing position (in which the lower wall of the blowing unit body 48 shown in FIG. 13 faces the tabletop 4) in which air is blown upward from the group of air outlets 28, or a horizontal blowing position (in which the left wall of the blowing unit body 48 shown in FIG. 15 faces the tabletop 4) in which air is blown sideways from the group of air outlets 28.

Inside the blowing unit main body 48, an air flow path 19 is provided that runs from the intake port 22 to the group of blowing ports 28. The air flow path 19 is composed of a horizontal flow path 87 that extends from the intake port 22 toward the left-right center, and a chamber 88 that is an internal space above the blowing unit main body 48 and communicates with the horizontal flow path 87. The ozone generating unit 12 and the supply means 13 are installed in the horizontal flow path 20. The group of blowing ports 28 is composed of rectangular blowing openings 89 that are long in the left-right direction and are divided by a large number of louvers 90 and arranged in a linear row. Each louver 90 is bent at the middle of the top and bottom, and when the angle between the extension direction of the part above the bent part and the vertical axis is defined as the louver angle, the louver angle of each louver 90 is set to increase from the center to the left and right ends. With the group of blowing ports 28 configured in this way, the air supplied by the supply means 13 forms a fan-shaped air curtain that spreads upward in the left-right direction.

Inside the blowing unit main body 48, excluding the air flow path 19, there are installed the control unit 15, a power supply battery 91 that supplies power to the ozone generating unit 12 and the supply means 13, and an attitude detection sensor 92 consisting of an acceleration sensor that detects the attitude of the blowing unit main body 48. The power supply battery 91 is a secondary battery and is located on the inner surface of the left wall of the blowing unit main body 48, and the control unit 15 and the attitude detection sensor 92 are located on the inner surface of the bottom wall of the blowing unit main body 48.

The sterilization and deodorization device 1 of this embodiment is provided with a human presence sensor 93 instead of a power switch, and is configured so that when the human presence sensor 93 detects a user, the control unit 15 drives the ozone generation unit 12 and the supply means 13. The human presence sensor 93 is provided on the upper wall of the blowing unit main body 48 so as to be adjacent to the group of blowing ports 28, and like the seating detection means 40 described above, can be configured as a heat detection sensor that uses infrared rays, or a distance measurement sensor that uses infrared rays or microwaves.

A stand (tilt adjustment means) 94 is provided to change the inclination of the blowing unit main body 48 in the horizontal blowing position. The stand 94 includes a pair of front and rear drawer walls 95, a bridge wall 96 that connects the two drawer walls 95 at the top, and a pivot shaft 97 that connects the two drawer walls 95 at the bottom. The pivot shaft 97 is inserted into an axis hole 98 that penetrates the blowing unit main body 48 from front to back, and the stand 94 can swing around the pivot shaft 97 relative to the blowing unit main body 48. A joint structure 99 is provided between the blowing unit main body 48 and the drawer wall 95, and the joint structure 99 consists of a joint projection 100 that protrudes from the inner surface of the drawer wall 95 and a joint recess 101 with which the joint projection 100 engages. Three joint recesses 101 are provided on an arc centered on the pivot shaft 97. The stand 94 can be pulled out in two stages, each at a specified angle, from a storage position where the outer surface of the stand 94 is flush with the surface of the blowing unit body 48. By pulling out the stand 94 and changing the inclination of the blowing unit body 48, which is in a lateral blowing position, the supply direction of the air blown out to the side can be adjusted up or down.

The tilt adjustment means 94 is not limited to the stand described above, but may be a leg that holds one end of the underside of the blowing unit main body 48 in the horizontal blowing position as a fulcrum so that the other end is raised. The leg (tilt adjustment means 94) can be composed of, for example, one plate or two rods that are rotatably supported on the blowing unit main body 48, or a plate or rod that is supported so that it can be freely extended and retracted from the blowing unit main body 48. It is also possible to provide a tilt adjustment means 94 for changing the tilt of the blowing unit main body 48 in the upward blowing position.

As described above, in the sterilization and deodorization device 1 of this embodiment, a group of air outlets 28 are arranged in a linear row, and the air blown out from the group of air outlets 28 is configured to form a fan-shaped air flow that expands in the direction of the row as it moves upward, so that an air curtain with a length greater than the formation length of the ozone blowing section 14 can be formed, and even with a compact ozone blowing section 14, a large invisible partition can be provided. In addition, sterilization and deodorization treatment can be performed over a wide area.

The blowing unit body 48 constituting the ozone blowing unit 14 is configured to be able to be set in either an upward blowing position in which air is blown upward from the group of blowing ports 28, or a horizontal blowing position in which air is blown sideways from the group of blowing ports 28. With this, when the blowing unit body 48 is in the upward blowing position, air containing ozone can be sent toward the top of the table 2, so that when people are having a conversation or eating face-to-face, the blowing unit body 48 can be set in the upward blowing position to provide an invisible partition between the people facing each other, and sterilization and deodorization treatment can be performed on the air above the table 2. Also, when the blowing unit body 48 is in the horizontal blowing position, air containing ozone can be sent toward the side of the table 2, so that when people are having a conversation or eating next to each other, the blowing unit body 48 can be set in the horizontal blowing position to provide an invisible partition between the people facing each other, and sterilization and deodorization treatment can be performed on the air to the side of the table 2.

(Example 8) Figures 16 and 17 show Example 8 of the sterilization and deodorization device according to the present invention. In this example, the ozone blowing section 14 is provided with a blowing section main body 48 made of a hollow body and a group of blowing ports 28 provided in the blowing section main body 48, and the sterilization and deodorization device 1 is configured by incorporating the ozone generating section 12, the feeding means 13, the ozone blowing section 14, the control section 15, the power supply battery 91, etc. in the blowing section main body 48. The sterilization and deodorization device 1 is configured to be hung and held on the top plate 4 of the table 2 by utilizing the shape of the blowing section main body 48, and can be attached to any position on the edge of the top plate 4. The blowing section main body 48 is composed of a blowing section case 104 in the shape of a horizontally elongated rectangular box and a hanging section 105 formed integrally with the rear side of the blowing section case 104. The hook 105 is made up of a pair of upper and lower clamping jaws 106, and the distance between the upper and lower clamping jaws 106 is set to be slightly larger than the thickness of the top plate 4. By attaching the sterilization and deodorization device 1 so that the top plate 4 is inserted between the upper and lower clamping jaws 106 from the side of the table 2, the ozone blowing unit 14 can be hooked and held on the edge of the top plate 4.

The intake port 22 is provided on the left wall of the blower case 104, and the group of blower ports 28 are provided on the top wall of the blower case 104. Inside the blower case 104, an air flow path 19 leading from the intake port 22 to the group of blower ports 28 and a chamber 88 are formed, with the ozone generator 12 installed in the center of the air flow path 19 and the supply means 13 installed near the intake port 22 of the air flow path 19. The control unit 15 and power battery 91 are installed inside the right side of the blower case 104, outside the air flow path 19.

The group of air outlets 28 is formed on the upper surface of the air outlet case 104. The group of air outlets 28 is configured by dividing rectangular air outlet openings 89 that are long in the left and right directions with a large number of louvers 90. Each louver 90 is inclined as a whole with respect to the vertical axis, and when the angle between the louver 90 and the vertical axis is defined as the louver angle, the louver angle of each louver 90 is set to increase from the center to the left and right ends. In addition, the opening area of each air outlet 28 defined by the lower end side of the louver 90 is set to increase from the center to the left and right ends. According to the group of air outlets 28 configured in this way, the wind pressure of the air blown out increases from the left and right center to the left and right ends in the group of air outlets 28, and the air blown out from the air outlets 28 on the end side is delivered upward from the center. A power button 67 for turning on and off the operation of the sterilization and deodorization device 1 is installed on the upper surface of the upper clamping jaw 106.

As described above, in the sterilization and deodorization device 1 of this embodiment, the wind pressure of the air blown out from each outlet 28 is set to increase from the center of the group of outlets 28 toward each end, so that the air blown out from the end side of the ozone blowing section 14 can be sent higher, forming the end part of the air curtain at the same height as the center part.

(Example 9) Figure 18 shows Example 9 of the sterilization and deodorization device according to the present invention. The sterilization and deodorization device 1 of this example differs from Example 8 in that it is configured to be hooked and held on the seat plate 6 of the chair 3 by utilizing the shape of the blowing unit main body 48. The distance between the upper and lower clamping jaws 106 constituting the blowing unit main body 48 is set to be slightly larger than the thickness dimension of the seat plate 6. By attaching the sterilization and deodorization device 1 from the back side of the chair 3 so that the seat plate 6 is inserted between the upper and lower clamping jaws 106, the ozone blowing unit 14 can be hooked and held on the back edge of the seat plate 6.

(Example 10) Figure 19 shows Example 10 of the sterilization and deodorization device according to the present invention. The sterilization and deodorization device 1 of this example differs from Example 9 in that it is configured to be hooked and held on the backrest 7 of the chair 3 by utilizing the shape of the blowing unit main body 48. The hooking part 105 constituting the blowing unit main body 48 is made of a recumbent L-shaped hook arm 107 in a side view, and by attaching the sterilization and deodorization device 1 so that the hook arm 107 hooks onto the backrest 7 from above the chair 3, the ozone blowing unit 14 can be hooked and held on the upper end of the backrest 7.

In the above-mentioned Examples 7 to 10, the ozone generating unit 12, the supply means 13, the control unit 15, etc. are configured to be built into the blowing unit main body 48, but as in Examples 2 and 3, the above devices may be built into the housing 18, and the air containing ozone may be supplied to the ozone blowing unit 14 via the connecting pipe 45, or as in Example 6, the air containing ozone may be supplied from an external unit 81.

(Example 11) Figures 20 to 22 show Example 11 of the sterilization and deodorization device according to the present invention. In this example, the ozone generating unit 12, the supplying means 13, the control unit 15, and the power supply battery 91 are housed in a casing 110 that is a shell-shaped thin box when viewed from the front to form the sterilization and deodorization device 1. The sterilization and deodorization device 1 is formed as a portable unit and can be placed on a table (desk) 2 so that its lower wall is in contact with the top plate 4. A hanging device 111 is connected to the casing 110, and the device is configured to be hung from the neck by the hanging device 111. The sterilization and deodorization device 1 can also be placed on the seat plate 6 of a chair 3.

An ozone blowing section 14 consisting of a group of blowing ports 28 is arranged at the top of the casing 110. An air intake 22 is opened on each of the left and right sides of the casing 110, and an air flow path 19 is formed inside the casing 110 from each air intake 22 to the group of blowing ports 28. The air flow path 19 is an inverted T-shaped flow path in front view, consisting of a horizontal flow path 20 extending in the left-right direction and a vertical flow path 21 extending in the up-down direction. The supply means 13 is installed at the junction of the horizontal flow path 20 and the vertical flow path 21, and the ozone generating section 12 is installed in the vertical flow path 21. The control section 15 and the power supply battery 91 are installed inside the casing 110 below the horizontal flow path 20.

The group of air outlets 28 (ozone blowing section 14) is configured by dividing air outlet openings 89, which are opened in the upper wall that curves upwards, with a number of louvers 90. Each louver 90 is arranged at equal intervals like the ribs of a fan, and the lower end of the louver 90 faces the downstream end of the vertical flow path 21. Air blown out from the group of air outlets 28 is sent upward so that it spreads out like a fan. A power button 67 is installed on the right side of the front of the casing 110.

The sling 111 is formed in a belt shape and is connected to a pair of sling connectors 112 provided on the left and right side surfaces of the casing 110. The sling connectors 112 are formed in a protruding tack button shape, and the sling 111 can be connected to the casing 110 by hooking the hanging holes 113 provided on both ends of the sling 111 to the sling connectors 112. The sling connectors 112 are arranged on the left and right side surfaces above the center of the vertical dimension of the casing 110, and are located above the installation positions of components such as the ozone generator 12, the feed means 13, the control unit 15, and the power battery 91 provided inside the casing 110. A plurality of hanging holes 113 can be provided at the ends of the sling 111 in the length direction of the sling 111. In this case, by changing the hanging hole 113 that is hung on the hanging tool connecting part 112, the overall length of the hanging tool 111 can be adjusted to hold the sterilization and deodorization device 1 at the vertical position of the user's preference.

As described above, in the sterilization and deodorization device 1 of this embodiment, the casing 110, which contains the ozone generating unit 12, the supply means 13, and the control unit 15 and has the ozone blowing unit 14 at its upper end, is formed as a portable unit that can be separated from the table 2 or the chair 3 and is configured to be hung from the neck by the hanging device 111, so that the sterilization and deodorization treatment can be performed on the air around the face by hanging the casing 110 from the neck as needed.

(Example 12) Figure 23 shows Example 12 of the sterilization and deodorization device according to the present invention. This example differs from Example 11 in that the intervals between adjacent louvers 90 are relatively narrow in the center of the ozone blowing section 14 and relatively wide at both ends. The opening area of each blowing outlet 28 defined by the lower end side of the louvers 90 is set to increase from the center to the left and right ends. With a group of blowing outlets 28 configured in this way, the wind pressure of the blown air increases from the left and right center to each left and right end side in the group of blowing outlets 28, and the air blown out from the blowing outlets 28 on the end side is delivered upward from the center, so that an air curtain that spreads widely in the left and right directions can be formed in front of the face.

(Example 13) FIG. 24 shows Example 13 of the sterilization and deodorization device according to the present invention. This example differs from Example 11 in that the downstream side of the vertical flow path 21 is divided into three divided flow paths 114, and a supply means 13 is installed in each divided flow path 114. The ozone generating section 12 is disposed in the vertical flow path 21 upstream of the supply means 13. The central divided flow path 114 communicates with three blowing ports 28 located in the center of the ozone blowing section 14, and each of the left and right divided flow paths 114 communicates with three blowing ports 28 located at the left and right ends of the ozone blowing section 14. In addition, the air supply capacity of the supply means 13 installed in the left and right divided flow paths 114 is set relatively large compared to the air supply capacity of the supply means 13 installed in the central divided flow path 114.

With the vertical flow path 21 and the supply means 13 configured in this way, the air supplied to the left and right divided flow paths 114 has a larger flow rate than the air supplied to the central divided flow path 114. Therefore, in a group of air outlets 28, the wind pressure of the air blown out increases from the left and right center toward each of the left and right ends, and the air blown out from the air outlets 28 at the ends is supplied upward from the center.

(Example 14) FIG. 25 shows Example 14 of the sterilization and deodorization device according to the present invention. This example differs from Example 11 in that the ozone generating unit 12 also serves as the supply means 13. The ozone generating unit 12 of this example has five pairs of discharge electrodes 33 and counter electrodes 34. The pair of electrodes 33 and 34 are installed in parallel in the left-right direction in the vertical flow path 21, with the discharge electrode 33 on the lower side and the counter electrode 34 on the upper side. Although not shown, the drive unit 35 constituting the ozone generating unit 12 is installed adjacent to the power battery 91. When a high voltage is applied between the discharge electrode 33 and the counter electrode 34 to generate a corona discharge, ions are generated along with ozone, and the ions accelerated by the discharge generate an airflow (ion wind) from the discharge electrode 33 toward the counter electrode 34, i.e., toward the ozone blowing unit 14. In this embodiment, the ion wind blows air containing ions toward the ozone blowing section 14, so the ozone generating section 12 is configured to also function as the supplying means 13.

In the above-mentioned Examples 11 to 14, an ozone changeover switch for switching the ozone generating unit 12 on and off can be provided separately from the power button 67. That is, the ozone generating unit 12 can be configured to be driven when the ozone changeover switch is in the on state, and stopped when the ozone changeover switch is in the off state. In this way, when the sterilization and deodorization device 1 is driven with the ozone changeover switch in the off state, the sterilization and deodorization device 1 can be used as an air curtain forming device using ozone-free air, or as a fan that supplies ozone-free air.

(Example 15) Figure 26 shows Example 15 of the sterilization and deodorization device according to the present invention. This example differs from Example 11 in that the casing 110 is composed of a main body 117 and a head 118 arranged at the upper end of the main body 117. The head 118 is connected to a support shaft 119 consisting of a horizontal axis extending in the left-right direction, and the support shaft 119 supports the head 118 so that it can tilt forward and backward relative to the main body 117. The ozone generator 12, the supply means 13, the control unit 15, the power battery 91, etc. are built into the main body 117, and the ozone blowing unit 14 consisting of a group of blowing ports 28 is provided on the upper wall (upper surface) of the head 118. In this embodiment, the casing 110 is composed of a main body 117 and a head 118, so that the vertical flow path 21 is divided into the main body 117 side and the head 118 side, but the divided parts are connected by a flexible tube (not shown), and the air containing ozone delivered by the delivery means 13 is delivered to the ozone blowing section 14 via the tube.

When the vertical extension direction of the main body 117 is aligned with the vertical axis in a side view, the head 118 is supported displaceably with respect to the main body 117 between a forward tilted position (shown by a solid line in FIG. 26) in which the blowing direction of the ozone blowing part 14 is tilted forward with respect to the vertical axis, and a backward tilted position (shown by a dashed line in FIG. 26) in which the blowing direction of the ozone blowing part 14 is tilted backward with respect to the vertical axis. The head 118 is configured to be held in each position by a joint structure (not shown) in the forward tilted position, the backward tilted position, and the upright position (shown by a two-dot chain line in FIG. 26) in which the blowing direction of the ozone blowing part 14 is aligned with the vertical axis. Note that the head 118 is temporarily held in the tilted position between each position by the frictional resistance of the support shaft 119 that connects the main body 117 and the head 118.

Between the main body 117 and the head 118, a posture detector 120 is provided to detect when the head 118 is in a forward tilted position. The posture detector 120 is composed of a non-contact switch consisting of a magnetic sensor 121 provided on the main body 117 and a magnet 122 provided on the head 118, and outputs an on signal or an off signal to the control unit 15. The magnetic sensor 121 outputs an on signal when it detects the magnet 122 (the head 118 is in a forward tilted position), and outputs an off signal when it does not detect the magnet 122 (the head 118 is not in a forward tilted position). Of course, the output of the off signal and the on signal of the magnetic sensor 121 may be reversed. The control unit 15 drives the ozone generator 12 and the supply means 13 when the posture detector 120 outputs an on signal, and stops the ozone generator 12 and drives only the supply means 13 when the posture detector 120 outputs an off signal. The attitude detector 120 can also be configured as a contact switch such as a limit switch instead of a non-contact switch.

When the sterilization and deodorization device 1 is hung from the neck by the hanging device 111 and held at the chest, and the sterilization and deodorization device 1 is driven with the head unit 118 in a forward tilted position, the air supply direction is away from the face, and more air is supplied in front of the face, so that an air curtain containing ozone can be formed in front of the face, and sterilization and deodorization treatment can be performed in front of the face. In addition, an invisible partition can be provided in front of the face, which can suppress the movement of air toward the other person when the user of the sterilization and deodorization device 1 and the person facing each other eat or talk, allowing them to enjoy meals and conversations without worrying about bad breath, etc. It can also be expected to prevent infection with viruses, etc. Since the partition provided by the air curtain is invisible, there is no need to worry about the partition.

When the sterilization and deodorization device 1 is hung from the neck by the hanging device 111 and held at the chest, and the head unit 118 is in an upright or backward position, the direction of the air supplied by the supply means 13 is close to the face, and more air comes into contact with the face, providing a feeling of coolness to the user. At this time, the ozone generating unit 12 is stopped, so the user does not smell the distinctive odor of ozone (ozone odor).

As described above, in the sterilization and deodorization device 1 of this embodiment, the casing 110 comprises a main body 117 equipped with a hanging device 111, and a head 118 supported so as to be tiltable back and forth relative to the main body 117. The ozone blowing section 14 is provided on the upper surface of the head 118, so that the direction of air blown out from the ozone blowing section 14 can be adjusted by tilting the head 118, and air containing ozone can be delivered to any position on the user's face, regardless of the position of the main body 117 held on the chest by the hanging device 111. For example, it is possible to deliver air to the face or to a position away from the face.

When the vertical extension direction of the main body 117 is aligned with the vertical axis, the head 118 is supported so as to be displaceable with respect to the main body 117 between an upright position in which the blowing direction of the ozone blowing unit 14 is aligned with the vertical axis, and a forward-leaning position in which the blowing direction of the ozone blowing unit 14 is inclined forward with respect to the vertical axis, as viewed from the side. In addition, a position detector 120 is provided to detect when the head 118 is in a forward-leaning position, and when the position detector 120 is on, the control unit 15 drives the ozone generating unit 12, and when the position detector 120 is off, the control unit 15 stops the ozone generating unit 12. According to this, when the head 118 is in an upright position, that is, when the air supply direction is close to the face and a large amount of air touches the face, the ozone generating unit 12 is stopped, and the user can be given a cool feeling without feeling the unique odor of ozone. In addition, when the head unit 118 is in a forward-leaning position, i.e., when the air supply direction is away from the face and more air is supplied in front of the face, the ozone generator 12 can be driven to perform sterilization and deodorization processing on the air in front of the face.

(Example 16) Figures 27 to 29 show Example 16 in which the sterilization and deodorization device according to the present invention is applied to a desk. This example differs from Example 1 in that the sterilization and deodorization device 1 is configured by incorporating the ozone generating unit 12, the supply means 13, the ozone blowing unit 14, the control unit 15, etc. in the unit case 125, and the sterilization and deodorization device 1 is fixed to the tabletop 4. The unit case 125 includes a unit base 126 that is cross-shaped in a plan view, and a cross-wall-shaped blowing wall 127 that is erected upward on the upper surface of the unit base 126.

The unit base 126 has front, rear, left and right base blocks 128, each of which has an air intake 22 on its end face, and each of which has an air flow path 19, an ozone generator 12 and a supply means 13 installed in the air flow path 19. The inside of the blowing wall 127 is hollow, and each of the downstream ends of the air flow paths 19 installed in the base block 128 communicates with the internal space of the blowing wall 127. The upper wall of the blowing wall 127 has a group of blowing ports 28 arranged in a cross shape, one in a straight line extending forward and backward, and the other in a straight line extending left and right. The control unit 15 is installed at the joint of the base blocks 128.

The sterilization and deodorization device 1 of this embodiment is equipped with a terminal device 131, which is provided on the front and rear surfaces of the blow-out wall 127 extending to the left and right. The terminal device 131 is equipped with a power button 132 for starting the terminal device 131, and a display unit 134 which also serves as an input means 133 consisting of a touch panel type liquid crystal. On the wall surface on which the terminal device 131 is attached, adjacent to the device 131, there is provided a seating detection means 40 which detects that a user has sat down in front of the terminal device 131 (display unit 134) and sends a seating signal to the control unit 15. The power button 132 also serves as a start-up switch 135 which sends a start-up signal to the control unit 15 to start the display unit 134. Of course, the start-up switch 135 can also be provided separately.

The control unit 15 includes a communication unit 136 for wirelessly transmitting and receiving information, and a timer 138 for measuring time. When a table 2 having an integrated sterilization and deodorization device 1 is installed in a store (e.g., a food court in a supermarket), the communication unit 136 is configured to be connectable to a store terminal 137 equipped with an order reception system installed in the store. The communication unit 136 is also configured to be connectable to the Internet. An order application for accessing the order reception system of the store terminal 137 via the communication unit 136 is installed in the terminal device 131, and commands such as orders can be sent from the terminal device 131 to the order reception system. The communication unit 136 can also be provided in each terminal device 131.

Next, a method of using the sterilization and deodorization device 1 according to this embodiment will be described. When a user presses the start switch 135 (power button 132), the start switch 135 transmits a start signal to the control unit 15. When the user sits in front of the terminal device 131 (display unit 134), the seating detection means 40 transmits a seating signal to the control unit 15. The control unit 15, which has received the start signal or seating signal (YES in step S1 or YES in step S2), executes a start-up step. In the start-up step, the control unit 15 starts the ozone generation unit 12, the supply means 13, and the terminal device 131 (step S3), and activates the timer 138. It is preferable that the control unit 15 activates the timer 138 when it receives a seating signal, and activates these devices when it receives a seating signal continuously for a predetermined time (e.g., 5 seconds), thereby preventing the sterilization and deodorization device 1 from being driven when a person passes through the detection range of the seating detection means 40.

When the ozone generating unit 12 and the supplying means 13 are started, air containing ozone is supplied upward from the group of air outlets 28, forming a cross-shaped air curtain above the top plate 4. When the terminal device 131 is started, various information can be displayed on the display unit 134, and input operations can be performed using the input means 133. When the start-up step of starting up these devices (ozone generating unit 12, supplying means 13, terminal device 131) is completed, the control unit 15 executes the display step. In the display step, the control unit 15 displays information on the display unit 134 to make the user aware that an air curtain is being formed with air containing ozone (e.g., "Sterilization and deodorization processing in progress") for a predetermined time (e.g., 30 seconds) (step S4).

Once the display step is complete, the control unit 15 executes the order reception step. In the order reception step, the control unit 15 starts the order application on the terminal device 131, and further accesses the store terminal 137 via the communication unit 136 to link the order application with the order reception system (step S5). When the link between the order application and the order reception system is established, the menu of the store registered in the order reception system is displayed on the display unit 134 to accept the order. At this time, the control unit 15 resets the timer 138 and then operates it again. Along with the menu, the display unit 134 displays a send button for sending the selected menu to the order reception system and a skip button for skipping the display of the menu without placing an order.

Then, the control unit 15 waits until the order acceptance time (e.g., 5 minutes) has elapsed to determine whether the order for the displayed menu is confirmed or the order is skipped (NO in step S6, NO in step S7, NO in step S8). In the order acceptance step, when the menu is confirmed using the input means 133 and the send button is selected (YES in step S6), the control unit 15 executes the order transmission step. In the order transmission step, the control unit 15 transmits the confirmed menu to the order acceptance system (step S9).

When the order sending step is completed (step S9) or the order is skipped in the order receiving step (YES in step S7), the control unit 15 moves to the viewing step. In the viewing step, the control unit 15 displays information (such as a web page) acquired via the communication unit 136 on the display unit 134 so that the information can be viewed. It is also possible to change the information displayed on the display unit 134 using the input means 133. Simultaneously with the transition to the viewing step, the control unit 15 resets the timer 138 and then operates it again to measure the elapsed time t of the viewing step.

When the elapsed time t of the viewing step reaches a predetermined cut-off time T, the control unit 15 stops driving the terminal device 131 (display unit 134). The cut-off time T is set differently depending on whether the order transmission step is completed and the process moves to the viewing step or whether the order is skipped in the order reception step and the process moves to the viewing step. The cut-off time TL(T) in the former case is set longer than the cut-off time TS(T) in the latter case.

When the order sending step is completed and the process moves to the viewing step, the control unit 15 sets the cutoff time TL (step S10), and when the timer 138 reaches the cutoff time TL (YES in step S11), it stops driving the terminal device 131 (display unit 134) (step S12). Next, after the cutoff time TL has elapsed, that is, when a predetermined time (e.g., 5 minutes) has elapsed since the terminal device 131 was stopped, the control unit 15 stops driving the ozone generation unit 12 and the supply means 13 (step S13), and stops the sterilization and deodorization device 1.

On the other hand, when an order is skipped and the process moves to the viewing step, the control unit 15 sets the cutoff time TS (step S14), and when the timer 138 reaches the cutoff time TS (YES in step S15), the control unit 15 stops driving the terminal device 131 (display unit 134) (step S12). Next, after the cutoff time TS has elapsed, that is, when a predetermined time (e.g., 5 minutes) has elapsed since the terminal device 131 was stopped, the control unit 15 stops driving the ozone generation unit 12 and the delivery means 13 (step S13), and stops the sterilization and deodorization device 1.

If the order acceptance time has elapsed in the above order acceptance step, the control unit 15 stops driving the terminal device 131 (display unit 134) (step S12), and when a predetermined time (e.g., 5 minutes) has elapsed, it stops driving the ozone generation unit 12 and the delivery means 13 (step S13), thereby stopping the sterilization and deodorization device 1.

The control unit 15 constantly monitors the signal from the seating detection means 40, and after the start-up step is completed, if the off signal continues for a predetermined time (e.g., 5 minutes), it determines that the user is not in front of the terminal device 131 (display unit 134) and stops the sterilization and deodorization device 1.

As described above, the sterilization and deodorization device 1 of this embodiment is equipped with a seating detection means 40 and a power button 132 (start-up switch 135), and the control unit 15 is configured to execute a start-up step that starts driving the ozone generation unit 12, the supply means 13, and the display unit 134 when a seating signal or a start-up signal is received, so that when the user operates the start-up switch 135 to view information on the display unit 134 or sits in front of the display unit 134, the sterilization and deodorization process can be started on the surrounding air. In addition, the control unit 15 is configured to execute a display step that displays on the display unit 134 an operation display indicating that air containing ozone is being blown out from the ozone blowing unit 14, so that the user can be made aware that the sterilization and deodorization process is being performed.

The control unit 15 is configured to execute, following the display step, an order receiving step of displaying on the display unit 134 menu data acquired from the store terminal 137 via the communication unit 136 and receiving an order from the user, and an order sending step of sending the order selected by the user to the store terminal 137. This allows the user to purchase products from the store while remaining seated at a table 2 installed in the store, improving user convenience.

The control unit 15 is configured to transition to a viewing step in which information obtained from the Internet via the communication unit 136 can be viewed on the display unit 134 when the order transmission step is completed or the order reception step is skipped. This allows the user to view information while waiting to receive a product purchased at the store, while eating or drinking, or while waiting for a short wait at the store, allowing the user to spend each of these times productively.

The control unit 15 is configured to stop driving the display unit 134 when a predetermined cut-off time T has elapsed after transitioning to the viewing step, and the cut-off time TS when the order reception step is skipped and transitioning to the viewing step is set to be shorter than the cut-off time TL when the order transmission step is completed and transitioning to the viewing step is made. In this way, when a product is purchased, information can be viewed for a longer period of time, which encourages the user to purchase the product. Furthermore, by setting the cut-off time T, it is possible to prevent users from using the table 2 for long periods of time.

The control unit 15 is configured to stop driving the ozone generating unit 12 and the supplying means 13 when a preset drive stop time has elapsed after the shutoff time T has elapsed, so that the drive of the ozone generating unit 12 and the supplying means 13 is automatically stopped, and unnecessary power consumption can be avoided.

The information displayed on the display unit 134 in the above display step (sterilization processing in progress) can continue to be displayed even after the display step is completed and the order acceptance step is started. In this case, the information is displayed smaller than in the display step, for example in a small corner of the display unit where it does not interfere with the order acceptance screen. The information display is then erased when the terminal device 131 is stopped (step S12). This makes it possible for the user to recognize that an air curtain has not been formed, further reducing prolonged use.

In the above embodiment, the sterilization and deodorization device 1 is configured to include a seating detection means 40 and a start switch 135 (power button 132), but it is sufficient if either the seating detection means 40 or the start switch 135 is provided. In other words, the start switch 135 can be omitted, and the seating detection means 40 can be configured as a means for starting the ozone generation unit 12, the supply means 13, and the display unit 134. In this case, the seating detection means 40 also serves as the start switch 135. Also, the seating detection means 40 can be omitted, and the start switch 135 can be configured as a means for starting the ozone generation unit 12, the supply means 13, and the display unit 134.
