Description

  The present invention relates to a bathroom air conditioner used for drying, ventilating, or heating clothes and a bathroom.

  In recent years, there has been an increase in mutual income for couples, and there has been an increasing demand for drying laundry indoors at night. Also, in the cold season such as winter, the interior of the bathroom before bathing in the bathtub is cold, and there is an increasing demand for warming up the bathroom before bathing.

  Thus, various bathroom air conditioners for drying, ventilating, or heating clothes and the bathroom have been proposed (see, for example, Patent Document 1).

  Moreover, what incorporates a negative ion generating means and ventilates the air containing a negative ion in a bathroom is also known (for example, refer patent document 2). Negative ions are said to have the effect of stabilizing the mind and enhancing the function of the respiratory organs.

  On the other hand, the bathroom is a hot and humid space, and even after ventilation after bathing, moisture remains for a while, so mold and tiles and ceiling tend to become unsanitary. For this reason, it is necessary to remove mold by spraying a chlorine-based chemical at the time of cleaning the bathroom, which not only requires time and effort for cleaning, but also makes the patient feel unwell.

Therefore, a space sterilization device such as an ozone generator is installed in the bathroom, and mold spores floating in the air are killed to prevent mold from adhering to the tiles and ceiling, creating a clean bathroom environment free from mold. The proposal which implement | achieves is made | formed (for example, refer patent documents 3-6).
JP 2002-333153 A JP 2002-130945 A JP 2002-253647 A JP 2002-333158 A JP 2002-333162 A JP 2002-162106 A

  However, since ozone gas is a harmful substance to humans, it is necessary to operate the ozone generator in a time zone where people do not enter or leave the bathroom, and even after treatment, the ozone generator enters the bathroom until the residual ozone gas drops to a safe concentration. There were many inconvenient points such as being unable to do so.

  Accordingly, it has been proposed to suppress the generation of mold by providing an ion generator for generating positive and negative ions in a bathroom and supplying positive and negative ions to the bathroom space to inactivate airborne bacteria. Since positive and negative ions are harmless to the human body, they can be safely released even when people are in the bathroom.

The principle of positive and negative ion generation is that a corona discharge is caused by boosting and applying an AC voltage taken from a household AC power source between a pair of electrodes facing each other so that a dielectric is interposed, and oxygen in the air Or water is ionized by receiving energy by ionization, and ions mainly composed of H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number). To be released. These H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n adhere to the surface of the floating bacteria and chemically react to generate H ₂ O ₂ or .OH as an active species. Since H ₂ O ₂ or .OH exhibits a very strong activity, they can surround and inactivate airborne bacteria in the air. Here, .OH is one kind of active species, and represents radical OH.

Positive and negative ions react chemically on the cell surface of airborne bacteria as shown in formulas (1) to (3) to generate hydrogen peroxide (H ₂ O ₂ ) or hydroxyl radical (.OH) as active species. To do. Here, in Formula (1)-Formula (3), m, m ', n, and n' are arbitrary natural numbers. Thereby, floating bacteria are destroyed by the action of decomposing active species. Accordingly, airborne bacteria can be inactivated and removed efficiently.
H ⁺ (H ₂ O) _m + O ₂ ⁻ (H ₂ O) _n → OH + _1/2 O ₂ + (m + n) H ₂ O (1)
H ⁺ (H ₂ O) _m + H ⁺ (H ₂ O) _{m ′} + O ₂ ⁻ (H ₂ O) _n + O ₂ ⁻ (H ₂ O) _{n ′} → 2.OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
H ⁺ (H ₂ O) _m + H ⁺ (H ₂ O) _{m ′} + O ₂ ⁻ (H ₂ O) _n + O ₂ ⁻ (H ₂ O) _{n ′} → H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)

In addition, since the above formulas (1) to (3) can produce the same action on the surface of harmful substances in the air, hydrogen peroxide (H ₂ O ₂ ) or hydroxyl radical (• OH) can be rendered virtually harmless by oxidizing or decomposing chemical substances such as formaldehyde and ammonia into harmless substances such as carbon dioxide, water and nitrogen.

  In addition, positive ions and negative ions have a function to inactivate viruses such as influenza virus and Coxsackie virus, and can prevent contamination due to contamination of these viruses.

  In addition, it has been confirmed that positive ions and negative ions have a function of decomposing molecules that cause odors, and can be used to deodorize spaces.

  Therefore, if this technology is used in a bathroom air conditioner, it is possible to inactivate mold and fungi in the bathroom atmosphere and keep the number of airborne bacteria below a certain level. Positive and negative ions have little action to inactivate molds and fungi attached to bathroom tiles and ceilings, but by suppressing the number of floating bacteria in this way, the adhesion of molds and fungi can be suppressed.

  Positive ions and negative ions have the property of disappearing when they come into contact with obstacles such as metals. For this reason, when installing an ion generator in a bathroom air conditioner, when placing a heat source such as a ceramic heater and an ion generator in the same air passage, be sure to place the ion generator downstream from the heat source. The decrease in the supply of positive and negative ions was suppressed.

  However, when the ceramic heater is arranged very close to the air outlet, it is difficult to bring the ion generator downstream of the ceramic heater due to the construction.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a bathroom air conditioner that can suppress the disappearance of positive and negative ions and sufficiently secure the supply amount of positive and negative ions into the bathroom.

  To achieve the above object, a bathroom air conditioner according to the present invention includes an air inlet facing the bathroom, an air outlet facing the bathroom, a circulation passage extending from the inlet to the outlet, A heat source provided in the circulation passage, a blower that circulates air in the bathroom or circulates air in the bathroom, and an air flow that branches from the upstream side of the heat source of the circulation passage and flows through the circulation passage. An ion duct for supplying ions and an ion generator provided in the ion duct and generating positive and negative ions by creeping discharge are provided.

  According to this configuration, positive and negative ions are generated from the ion generator in the ion duct branched from the upstream side of the heat source of the circulation passage, and the generated positive and negative ions finally flow through the circulation passage through the ion duct. Supplied to the stream.

  An air inlet facing the bathroom, an air outlet facing the bathroom, a ventilation opening for exhausting the air inside the bathroom to the outdoors, a circulation passage extending from the inlet to the outlet, and A heat source provided in the circulation passage, an exhaust passage from the suction port to the ventilation port, a blower that circulates air in the bathroom or air in the bathroom, and an upstream side of the heat source in the circulation passage An ion duct for supplying positive and negative ions to an air flow that branches and flows through the circulation passage, and an ion generator that is provided in the ion duct and generates positive and negative ions by creeping discharge are provided. .

  According to this configuration, positive and negative ions are generated from the ion generator in the ion duct branched from the upstream side of the heat source of the circulation passage, and the generated positive and negative ions finally flow through the circulation passage through the ion duct. Supplied to the stream.

  Since the wind blown from the ion duct during bathing is cold when it directly hits the body, the outlet of the ion duct is opened to the outlet, and a damper for opening and closing the inlet of the ion duct is provided so that the interior of the bathroom is sufficient Until the air is heated, the entrance of the ion duct is preferably closed by a damper. Alternatively, the outlet of the ion duct may be opened to the circulation passage so as to bypass the heat source. Alternatively, the ion duct is branched, the outlet of the ion duct is opened to both the outlet and the circulation passage, and a damper for switching the outlet of the ion duct is provided at the branch, Until the heater is sufficiently heated, the outlet on the outlet side of the ion duct may be closed by a damper.

  According to the present invention, an ion generator is provided in an ion duct branched from the upstream side of the heat source of the circulation passage so that positive and negative ions generated in the ion duct are supplied to the air flow flowing through the circulation passage. Therefore, the heat source, which is an obstacle that reduces the amount of positive and negative ions, can be avoided by the ion duct branching from the circulation passage, and the supply of positive and negative ions into the bathroom can be secured sufficiently by suppressing the disappearance of positive and negative ions. be able to.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a bathroom air conditioner according to the present invention, and FIG. 2 is a schematic view showing a state of attachment to the bathroom. The bathroom air conditioner 1 is roughly constituted by a main body 4 mounted inside the opening 3 of the ceiling board 2 and a panel 5 attached to the main body 4 so as to be positioned below the ceiling board 2. The opening 3 of the ceiling board 2 is formed so that the panel 5 is positioned on the bathtub 12 inside the bathroom 11. On the panel 5, a human body sensor 14 for detecting the presence of a person is provided.

  In the center of the panel 5, two slit-shaped vents with different widths are provided side by side. That is, a wide suction port 6 is formed on the left side, and a narrow air outlet 7 is formed on the right side.

  Next to the bathtub 12 is a washing place 13, and an inspection port 15 and a lid 16 are provided in a portion of the ceiling board 2 located above the washing place 13. The door 17 is formed with a gallery 18 serving as a ventilation opening. A controller 19 and a switchboard 20 of the bathroom air conditioner 1 are disposed on the outer wall surface of the bathroom 11, and the controller 19 and the switchboard 20 are connected to the bathroom air conditioner 1 through a power line and a control line, respectively. The main body 4 is connected to the exhaust ducts 21 and 22 so that the air in the bathroom 11 sucked by the main body 4 can be exhausted outdoors.

  FIG. 3 is a schematic cross-sectional view of the bathroom air conditioner 1. An axial flow type fan 24 that rotates in the horizontal direction is provided on the upper left side in the main body 4. The fan 24 is fixed to a shaft of a fan motor 25 provided outside the upper surface of the main body 4. Further, the inside of the main body 4 is divided into a lower left room 28 and an upper and right room 29 by a partition member 27 that also serves as a fan casing. The partition member 27 is formed in a cylindrical shape as an introduction opening portion 27A where the portion facing the lower surface of the fan 24 faces the room 28, and a portion facing the air outlet 7 of the panel 5 as a discharge opening portion 27B. The interior of the bathroom 11 and the room 28 communicate with each other through the suction port 6 of the panel 5, the rooms 28 and 29 communicate with each other through the introduction opening 27A, and the air outlet 7 that overlaps the downstream end of the discharge opening 27B. The room 29 communicates with the inside of the bathroom 11. The room 28 is an upstream area of the fan 24, and the room 29 is a downstream area of the fan 24.

  In the main body 4, a circulation passage extending from the suction port 6 through the rooms 28 and 29 to the outlet 7 and an exhaust passage extending from the suction port 6 through the rooms 28 and 29 to the ventilation port 8 are formed. A damper 9 for switching the air flow of the fan 24 to either one or both is provided at a branch portion between the circulation passage and the exhaust passage.

  Here, the damper 9 is used to switch between the circulation passage and the exhaust passage, but the present invention is not limited to this.

  A heat source such as a ceramic heater 30 is provided in a circulation passage located on the downstream side of the damper 9 in the room 29, that is, in the introduction opening 27B. An ion generator 23 that generates positive and negative ions is provided further downstream of the ceramic heater 30. The discharge surface 23A of the ion generator 23 is arranged so as to follow the airflow flowing through the air discharge opening 27B, and positive and negative ions generated from the ion generator 23 ride on the airflow from the outlet 7 to the bathroom 11. Will be supplied inside. A flat plate-shaped shield 47 is rotatably fixed to the inner wall of the air discharge opening 27 </ b> B so as to be adjacent to the ion generator 23 on the downstream side of the ion generator 23. The shield 47 is positioned between the closed position that protects the discharge surface 23A from water droplets in the horizontal direction as shown in FIGS. 3 to 5 and the open position along the inner wall of the air discharge opening 27B as shown in FIG. You can rotate and change the posture. A humidity sensor 31 is provided on the upstream side of the damper 9 in the room 29.

  FIG. 7 is a schematic enlarged cross-sectional view of the ion generator 23. The ion generating device 23 is a box-shaped casing 211 in which an ion generating element 210 having a pair of electrodes arranged with a flat-plate dielectric interposed therebetween, a step-up transformer (not shown), and the like are accommodated. The ion generating element 210 is attached using a rectangular opening provided on one surface of the casing 211 as a frame, and the exposed surface forms a discharge surface 23A. Further, a flat plate heater 48 that generates resistance heat is attached to the back surface of the ion generating element 210, and the ion generating element 210 can be heated by energizing the heater 48 as necessary. It has become.

  FIG. 8 shows a control block diagram of the bathroom air conditioner 1. A control unit 32 comprising a microcomputer is connected to the switchboard 20 and receives power supply, and controls the rotational speed of the fan 24, the positions of the dampers 9, 47, the energization of the ceramic heater 30, the heater 48 and the ion generator 23. Therefore, various operation modes are realized by individually controlling these operations based on the operation of the controller 19. There are four typical operation modes: heating, ventilation, cool breeze, and drying. In addition, the control unit 32 has a built-in timer 33 for measuring time, and the user can switch between an on timer that turns on at a predetermined time and a turn off timer that turns off the power.

  Next, each operation mode of the bathroom air conditioner 1 will be described with reference to FIGS. The heating mode is an operation mode in which the bathroom 11 is warmed before taking a bath in the cold winter season. When this mode is selected, the control unit 32 opens the ventilation port 8 by the damper 9 as shown in FIG. By closing and driving the fan motor 25, the air flow of the fan 24 is switched to the circulation passage, and the air in the bathroom 11 is circulated as shown by the arrow A. Further, the ceramic heater 30 is energized. The air heated by the ceramic heater 30 is sent into the bathroom 11 and the temperature in the bathroom 11 rises. Thereby, an increase in blood pressure and an uncomfortable feeling due to a rapid temperature change before and after bathing can be prevented. When the human body sensor 14 detects the presence of a person, the ion generator 23 may be driven to generate negative ions. When this mode is selected, the shield 47 is closed as shown in FIG. 3, and the downstream area of the discharge surface 23A of the ion generator 23 is shielded. As a result, even if water droplets scattered in the bathroom 11 pass through the air outlet 7 and enter the main body 4, the water droplets can be prevented from adhering to the discharge surface 23 </ b> A because they are protected by the shield 47. .

  The ventilation mode is an operation mode in which the bathroom 11 is dried with a strong ventilation function. When this mode is selected, the control unit 32 closes the inlet of the air discharge unit 27A by the damper 9 as shown in FIG. By driving the fan motor 25, the air flow of the fan 24 is switched to the exhaust passage, and the air in the bathroom 11 is exhausted outdoors as indicated by the arrow B. At this time, the ceramic heater 30 is not energized. The humid air in the bathroom 11 is exhausted to the outside, and the interior of the bathroom 11 is dried. Note that the ion generator 23 may be arbitrarily driven. In this case, positive and negative ions are sent into the duct 21 to inactivate mold and germs floating in the duct 21, and mold is generated in the duct 21. It can be prevented from occurring. When this mode is selected, the shield 47 is closed as shown in FIG. 4, and the downstream area of the discharge surface 23A of the ion generator 23 is shielded. As a result, even if water droplets scattered in the bathroom 11 pass through the air outlet 7 and enter the main body 4, the water droplets can be prevented from adhering to the discharge surface 23 </ b> A because they are protected by the shield 47. .

  The cool breeze mode is a mode in which the bathroom air conditioner 1 is used as a fan during bathing in a hot and humid time such as summer. When this mode is selected, the control unit 32 places the damper 9 in an intermediate position as shown in FIG. And the fan motor 25 is driven to switch so that the air flow of the fan 24 flows in both the circulation passage and the exhaust passage, and the air in the bathroom 11 is circulated as indicated by the arrow A, and the arrow Exhaust a part outdoors like B. At this time, the ceramic heater 30 is not energized. Thereby, it blows gently in the bathroom 11, and a bather can cool down. When the human body sensor 14 detects the presence of a person, the ion generator 23 may be driven to generate negative ions. When this mode is selected, the shield 47 is closed as shown in FIG. 5, and the downstream area of the discharge surface 23A of the ion generator 23 is shielded. As a result, even if water droplets scattered in the bathroom 11 pass through the air outlet 7 and enter the main body 4, the water droplets can be prevented from adhering to the discharge surface 23 </ b> A because they are protected by the shield 47. .

  In this cool breeze mode, positive and negative ions may be generated from the ion generator 23. Generating positive and negative ions in this mode is not affected by a heat source such as the ceramic heater 30 and exhausts the air in the bathroom 11, so that the humidity is lowered and it is more effective in preventing mold.

  The drying mode is an operation mode in which clothes such as clothes are hung in the bathroom 11 and dried. When this mode is selected, the control unit 32 controls the fan 24 as shown in FIG. The air flow is switched so as to flow in both the circulation passage and the exhaust passage. Further, the ceramic heater 30 and the ion generator 23 are energized. The air heated by the ceramic heater 30 is sent into the bathroom 11 and the temperature in the bathroom 11 rises. Moisture evaporated from the laundry is exhausted outdoors, and the laundry is dried. When this mode is selected, the shield 47 is opened as shown in FIG. 6, and the downstream area of the discharge surface 23A of the ion generator 23 is opened. As a result, positive and negative ions generated from the ion generator 23 are sent into the bathroom 11 and molds and germs floating in the bathroom 11 are inactivated, thereby preventing mold from being generated in the bathroom 11 and the laundry. be able to.

  The energization of the ceramic heater 30 can be controlled so that positive and negative ions can be appropriately generated, and hot air and positive and negative ions can be mixed and supplied into the bathroom 11. If the amount of ion generation increases when the temperature in the bathroom 11 is increased, the energization of the ceramic heater 30 is increased to increase the amount of heat generation, and if the temperature is decreased, the energization to the ceramic heater 30 is performed. It is also possible to reduce the heat generation amount. In consideration of the case where the ion generator 23 is affected by the heat of the ceramic heater 30 on the upstream side of the ceramic heater 30 and hinders the generation of ions, the energization to the ceramic heater 30 is performed during or after the drying mode. By turning off and controlling energization so as to reduce the amount of heat generated, more positive and negative ions can be generated and supplied into the bathroom 11.

  As described above, it is possible to guard the discharge surface 23 </ b> A of the ion generator 23 with the shield 47 against water droplets flying directly from the bathroom 11, but condensation on the discharge surface 23 </ b> A may be prevented with the shield 47. Absent. In particular, since the interior of the bathroom 11 after each operation mode is filled with moisture, condensation tends to occur on the cold discharge surface 23A, and the discharge surface 23A becomes wet unless effective countermeasures are taken. This causes inconveniences such as a decrease in the amount of ions generated during execution of the drying mode.

  Therefore, the drying operation of the discharge surface 23A is performed as follows. FIG. 9 is a flowchart of the control. When an operation mode involving the generation of ions is selected, the timer 33 is activated in step # 1, the fan 24 is driven in steps # 2 and # 3, and the heater 48 is energized. Thereby, since the ion generating element 210 is heated and blown to the discharge surface 23A, water droplets on the discharge surface 23A quickly evaporate and condensation can be eliminated. When a certain time has passed in step # 4, the energization of the heater 48 is turned off in step # 5, then the ion generator 23 is driven in step # 6, and the operation mode with ion generation is performed in step # 7. Will be executed. At this time, the discharge surface 23A is sufficiently dry, and the generation amount of positive and negative ions can be ensured. In step # 1, the ceramic heater 30 may be energized in place of the heater 48 or in combination with the heater 48 to send warm air to the discharge surface 23A.

  The heating means may be a heat source such as a heater 48 provided on the discharge surface 23A, or a heat source such as a ceramic heater 30 provided for generating hot air of the main body 4, or both of them may be used. Moreover, it is good also as only ventilation with the fan 24 of the ion generator 23. FIG. The moisture removal operation for drying the discharge surface 23A of the ion generator 23 may be provided as a single mode, but it is preferable to link with the heating, ventilation, cool breeze, drying mode, etc. of the bathroom air conditioner 1, and the ion generation is performed. It is preferable to do it before doing. In addition, it is preferable that the user removes moisture from the discharge surface 23A of the ion generator 23 without using the ion generation switch in conjunction with each mode.

  This moisture removal operation may be controlled using the humidity sensor 31 as shown in FIG. That is, the moisture sensor operates in step # 11 of FIG. 10, and the moisture removal operation similar to that in FIG. 9 is performed until it is determined in step # 14 that the humidity has become a predetermined reference value (for example, 40% RH) or less. Is what you do.

  Further, as a drip-proof moisture removing means, an ion generator 23 may be provided upstream of a heat source such as the ceramic heater 30 as shown in FIG. Even when water such as a shower is accidentally sprayed from the air outlet 7 by a heat source such as a heater, it is possible to prevent water droplets from adhering to the bathroom 11.

  Next, a second embodiment of the present invention will be described. FIG. 11: is a schematic sectional drawing of the bathroom air conditioner (refer FIGS. 3-6) which concerns on 2nd Embodiment. In this figure, the same code | symbol is attached | subjected to the same member as the bathroom air conditioner 1 which concerns on the said 1st Embodiment, and the detailed description is abbreviate | omitted.

  As described above, in the heating or drying mode of the bathroom air conditioner 1, hot air is blown into the bathroom 11, but in order to increase heating or drying efficiency, the ceramic heater 30 may be disposed as close to the outlet 7 as possible. desirable.

  On the other hand, positive and negative ions have a property of disappearing when they come into contact with an obstacle such as a metal. For this reason, in the bathroom air conditioner 1 according to the present invention equipped with the ion generator 23, when the ceramic heater 30 and the ion generator 23 are arranged in the same air passage, the ion generator 23 is always placed more than the ceramic heater 30. It arrange | positioned in the downstream and suppressed the reduction | decrease in the supply amount of positive / negative ions (for example, refer FIGS. 3-6).

  However, when the ceramic heater 30 is disposed very close to the air outlet 7, it is difficult to bring the ion generator 23 downstream of the ceramic heater 30 due to the configuration. Therefore, as shown in FIG. 11, an ion duct 49 that branches to the discharge opening 27 </ b> B on the upstream side of the ceramic heater 30 and opens to the air outlet 7 is made of the same material as the partition member 47. An ion generator 23 is provided so that the discharge surface 23A faces the flow path.

  Thereby, the obstruction (ceramic heater 30) which decreases the amount of positive / negative ions can be avoided, and the supply amount of positive / negative ions into the bathroom 11 can be ensured. In addition, when driving the ion generator 23 in the heating mode, if the blowout of ions and hot air is separately performed in this manner, it is cold when the wind blown from the ion duct 49 during bathing directly hits the body. It is preferable to close the entrance of the ion duct 49 until the damper 50 is provided at the entrance of the ion duct 49 and the inside of the bathroom 11 is sufficiently heated. Alternatively, as shown in FIG. 12, the outlet 49 </ b> A of the ion duct 49 may be opened in the circulation passage in the introduction opening 27 to bypass the ceramic heater 30. Alternatively, as shown in FIG. 13, the ion duct 49 is branched and the outlet 49 </ b> A is opened in both the circulation passage in the introduction opening 27 and the outlet 7, and the bathroom 11 is provided with a damper 51 provided in the branch. Until the inside is sufficiently heated, the outlet 49A on the outlet 7 side may be closed.
