(Knowledge and other information that formed the basis of this disclosure)
At the time the inventors conceived this disclosure, there was a technology that supplied mist to dried laundry using a mist generating device that generated mist by applying ultrasonic vibrations to water stored in a water reservoir. Given this situation, the inventors conceived the idea of effectively treating items to be treated, such as clothing, or to a washing machine by spraying a liquid agent as mist using a mist supply means. However, the inventors discovered that there were several problems when spraying a liquid agent using a mist supply means.

Firstly, when spraying liquid agents using a mist supply device, there is a challenge in reducing the risk of the user inhaling the mist. In particular, when a two-fluid nozzle is used as the spray nozzle for the mist supply device, a mist with small particle sizes is sprayed. When spraying a mist with large particle sizes, the mist is heavy and falls quickly, making it difficult to uniformly adhere to the target. When spraying a mist with small particle sizes, the suspension time is longer, allowing for uniform adhesion to the target. However, if the user opens the lid while a mist of a small-particle liquid agent sprayed by the mist supply device remains in the container, there is a risk of the user inhaling the mist. Unlike conventional mist generators that spray water, when spraying liquid agents, it is necessary to suppress the user from inhaling the mist.

Secondly, there is the challenge of preventing clogging of the liquid in the mist supply system. For example, if the system allows the user to change the liquid contained in the liquid tank, and the mist supply system sprays the liquid contained in the tank, there is a risk that after changing the liquid, the liquids may mix within the mist supply system, leading to the formation of solidified material and potentially causing clogging. Furthermore, if clogging occurs within the mist supply system, it becomes necessary to replace or maintain a portion of the system.

The inventors identified the above-mentioned problems and, in order to solve these problems, arrived at the subject matter of this disclosure.

The embodiments will be described in detail below with reference to the drawings. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters or substantially identical configurations may be omitted. This is to avoid the following explanation becoming unnecessarily verbose and to facilitate understanding for those skilled in the art.

The attached drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.

(Embodiment 1)
Embodiment 1 will be described below with reference to Figures 1 to 14. In Embodiment 1, a dryer 100 will be described as an example of a clothing processing device.

[1-1. Structure]
[1-1-1. Dryer Configuration]
The configuration of the dryer 100 will be explained using Figures 1 and 2. Figure 1 is a front view of the dryer 100. Figure 2 is a longitudinal cross-sectional view of the main part of the dryer 100.

The dryer 100 comprises a housing 101, a drum 102, a lid 120, and an operation display unit 125. The housing 101 includes a front plate 101a that forms the front side of the dryer 100, and a tank cover 101b provided at the lower front of the housing 101.

The drum 102 is housed within the housing 101. The drum 102 is rotatably mounted within the housing 101, with a rotation axis X extending substantially horizontally as its central axis. The drum 102 is formed in a closed-bottom cylindrical shape with a drum opening 102a on its front side, and houses the object to be processed. Examples of objects to be processed that can be housed in the drum 102 include clothing, shoes, bags, and hats. In this embodiment, an example in which clothing is housed in the drum 102 will be described below.

A motor 105 is located on the lower rear side of the housing 101. The motor 105 rotates the drum 102.

The lid 120 is attached to the front plate 101a and covers the drum opening 102a in a way that allows it to be opened and closed. The user opens the lid 120 and places the material to be processed into the drum 102 through the drum opening 102a. The dryer 100 also includes a lid locking mechanism. The lid locking mechanism can hold the lid 120 in the closed position.

A tank cover 101c is provided inside the housing 101, covering a portion of the drum opening 102a (as shown in Figures 2, 6, and 7). In a front view of the dryer 100, the tank cover 101c covers the outer periphery of the drum opening 102a beyond the lid 120. The tank cover 101c may be provided continuously with the front plate 101a, or as a separate component.

A baffle 103 is provided on the inner wall of the drum 102. The baffle 103 lifts the contents inside the drum 102 when the drum 102 rotates.

An air intake port 106 for drawing air from inside the drum 102 is provided at the inner front of the housing 101. A fan 104, which serves as a means of blowing air into the drum 102, is provided at the inner rear of the housing 101. The fan 104 is located outside the drum 102. When the fan 104 rotates, air is drawn in through the air intake port 106 and blown into the drum 102 through the air outlet 107 located at the rear of the drum 102. In this embodiment, the airflow path from the air intake port 106 to the air outlet 107 into the drum 102 is defined as the airflow path 110. The fan 104 is located in the airflow path 110. A heater 111 is provided in the airflow path 110 to heat the air passing through it.

An operation display unit 125 is provided on the upper front of the housing 101. The operation display unit 125 is configured to receive operating instructions from the user and to display the operating status of the dryer 100, etc.

A control device 130 is provided in the lower part of the housing 101. The control device 130 controls the operation of the fan 104, motor 105, and heater 111, among other components. The configuration of the control device 130 will be described later.

[1-1-2. Configuration of the liquid spraying device]
A liquid spraying device 140 for supplying mist into the drum 102 is provided inside the housing 101. The liquid spraying device 140 will be described below with reference to Figures 3 and 4. Figure 3 is a schematic diagram showing the main components of the liquid spraying device 140. Figure 4 is a longitudinal cross-sectional view of the dryer 100 including the liquid spraying device 140.

The liquid atomizing device 140 is located outside the air supply path 110. The liquid atomizing device 140 includes a liquid tank 141, a liquid supply path 142, an air pump 143, an air supply path 144, and a nozzle unit 150 including a spray nozzle 154 (described later).

The liquid tank 141 is designed to store liquid. Examples of liquids that can be stored in the liquid tank 141 include wrinkle removers, disinfectants, deodorizers, fragrances, insect repellents, pre-cleaning agents, water repellents, and stain repellents. Water may also be stored in the liquid tank 141. The liquid tank 141 is located in the lower interior part of the housing 101. The user can change, refill, and replenish the liquid in the liquid tank 141 by opening the tank cover 101b and removing the liquid tank 141 from inside the housing 101. The location of the tank cover 101b is not limited to the lower front of the housing 101, as long as it allows the user to remove the liquid tank 141; it can be determined according to the location of the liquid tank 141.

The liquid supply path 142 is the path through which the liquid contained in the liquid tank 141 is supplied to the spray nozzle 154. In other words, the liquid supply path 142 is the path through which the liquid flowing into the spray nozzle 154 passes.

The air pump 143 is a device that supplies compressed air to the spray nozzle 154.

The air supply path 144 is connected to the air pump 143. The air supply path 144 is the path through which the air flowing into the spray nozzle 154 passes.

As shown in Figure 4, the nozzle unit 150 is positioned above the liquid tank 141. This allows the liquid in the liquid supply path 142 to return towards the liquid tank 141 when the liquid spraying device 140 is stopped, thus preventing liquid from remaining in the liquid supply path 142. Preferably, to prevent liquid from remaining in the liquid supply path 142, the liquid supply path 142 should be positioned so that it gradually rises from the liquid tank 141 towards the nozzle unit 150.

In this embodiment, the liquid supply path 142 and the air supply path 144 are formed from rubber tubing, but the material and form of the liquid supply path 142 and the air supply path 144 are not limited.

[1-1-3. Nozzle Unit Configuration]
The configuration of the nozzle unit 150 will be explained using Figures 5 to 7. Figure 5 is an exploded perspective view of the nozzle unit 150. Figure 6 is a cross-sectional view of the dryer 100, looking from the middle to the front in the front-to-back direction. Figure 7 is a partially enlarged view of Figure 6.

The nozzle unit 150 includes a base portion 151, a nozzle portion 152, and a nozzle cover 155.

The base portion 151 is a component for attaching the nozzle unit 150 to the tank cover 101c, and is detachably mounted on the tank cover 101c. The base portion 151 is fixed to the tank cover 101c by being screwed in. In this embodiment, the base portion 151 is screwed in from the inside of the tank cover 101c to the inner back surface of the tank cover 101c.

The nozzle section 152 includes a nozzle mounting section 153 and a spray nozzle 154. The nozzle section 152 is fixed to the mounting surface 151a of the base section 151 by screw fastening, with the spray nozzle 154 attached to the nozzle mounting section 153. The nozzle mounting section 153 is detachably mounted to the mounting surface 151a of the base section 151. In other words, the nozzle section 152 is detachably mounted to the base section 151.

The nozzle mounting section 153 connects the air supply path 144 to the air-side connection section 154a (described later) of the spray nozzle 154. An O-ring may be provided at the connection point between the air supply path 144 and the nozzle mounting section 153 to prevent air leakage.

The spray nozzle 154 is a two-fluid nozzle that sprays liquid using compressed air. The spray nozzle 154 includes an air-side connection part 154a, a liquid-side connection part 154b, and a spray port 154c. The air-side connection part 154a is connected to the nozzle mounting part 153 and allows air that has passed through the air supply path 144 to flow into the spray nozzle 154. The liquid-side connection part 154b is connected to the liquid supply path 142 and allows liquid that has passed through the liquid supply path 142 to flow into the spray nozzle 154. The spray port 154c uses the compressed air flowing in from the air-side connection part 154a to spray the liquid contained in the liquid tank 141 that has flowed in from the liquid-side connection part 154b.

The air-side connection portion 154a and the spray nozzle 154c are positioned approximately in a straight line, while the air-side connection portion 154a and the liquid-side connection portion 154b are positioned approximately perpendicular to each other. An O-ring may be provided at the connection point between the air-side connection portion 154a and the nozzle mounting portion 153 to prevent air leakage. Furthermore, an O-ring may be provided at the connection point between the liquid-side connection portion 154b and the liquid supply path 142 to prevent liquid leakage.

The nozzle section 152 is sandwiched between the base section 151 and the nozzle cover 155 when the spray nozzle 154 is attached to the nozzle mounting section 153. It is fixed to the base section 151 by screws through screw holes in the mounting surface 151a and the nozzle cover 155 through screw holes in the nozzle mounting section 153. In other words, the nozzle cover 155 fixes the nozzle section 152 to the base section 151. The nozzle mounting section 153 and the nozzle cover 155 are sealed in the radial direction. Since radial sealing has a high tolerance for assembly variations, stable sealing can be ensured when disassembling and reassembling the nozzle unit 150 for replacement.

The base portion 151, which has an installation surface 151a, is detachably attached to the tank cover 101c. This allows the installation angle of the nozzle portion 152 to be changed by replacing the base portion 151 with one having a different angle of installation surface 151a on the tank cover 101c. Therefore, the angle of the spray nozzle 154c can be changed, allowing the angle of the mist sprayed from the spray nozzle 154 to be altered depending on the type of liquid contained in the liquid tank 141 and the intended use of the liquid spraying device 140.

The nozzle mounting section 153 has an air supply path 144 connected to it in a substantially vertical direction and is connected to the air-side connection section 154a of the spray nozzle 154 in a substantially horizontal direction. In other words, the nozzle mounting section 153 has a bending structure 153a that bends the path within the nozzle mounting section 153 at a substantially right angle. To put it another way, the bending structure 153a bends the path through which the air flowing into the spray nozzle 154 passes. This reduces the space required by the nozzle section 152, in this embodiment, the space in the front-to-back direction. Furthermore, due to the bending structure 153a, the liquid supply path 142 and the air supply path 144 are provided extending in substantially the same direction, in this embodiment, substantially vertically downward from the nozzle section 152. This reduces the space required by the nozzle section 152, in this embodiment, the space in the front-to-back direction, thus enabling space saving when installing the nozzle section 152. Furthermore, since the liquid supply path 142 and the air supply path 144 can be connected to the liquid-side connection portion 153b and nozzle mounting portion 153 of the spray nozzle 154 from the same direction, the nozzle portion 152, liquid supply path 142, and air supply path 144 can be easily replaced.

As shown in Figures 6 and 7, the spray nozzle 154 is located on the upper left (front view) of the drum cover 101c. In other words, the spray nozzle 154 is located on the upper front side of the drum 102. The spray nozzle 154 sprays mist diagonally across the drum 102, towards the lower right (front view) of the rear inside of the drum 102. Since the mist sprayed from the spray nozzle 154 falls downward due to gravity, its location on the upper front of the drum 102 prevents localized mist adhesion to the clothes stored inside the drum 102, allowing for wider mist coverage.

[1-1-4. Configuration of the control device]
The configuration of the control device 130 will be explained using Figure 8. Figure 8 is a block diagram of the control device 130.

The control device 130 includes a control unit 131, a reception unit 132, and a notification unit 133.

The control unit 131 controls the operation of the fan 104, motor 105, heater 111, air pump 143, and lid locking mechanism.

The reception unit 132 receives instructions from the user via the operation display unit 125. In response to the instructions, such as the driving course, received by the reception unit 132, the control unit 131 controls the operation of the aforementioned devices.

The notification unit 133 informs the user of the operating status of the dryer 100, etc., through the operation display unit 125 and a buzzer.

Furthermore, if the dryer 100 is equipped with a communication unit capable of communicating with an external terminal, the reception unit 132 may be configured to receive instructions input from the user via the external terminal through the communication unit. Additionally, the notification unit 133 may be configured to notify the user of the operating status of the dryer 100, etc., via the communication unit to the external terminal.

[1-2. Operation, etc.]
The operation and function of the dryer 100, configured as described above, will now be explained.

[1-2-1. Operation in the mist supply course]
The control unit 131 can execute a mist supply course that controls the air pump 143 to operate the liquid spray device 140. The mist supply course is a course that operates the liquid spray device 140 with clothes contained in the drum 102. The control and operation in the mist supply course will be explained below with reference to the figures. Figure 9 is a flowchart of the mist supply course.

The mist supply course includes a spraying step that operates the liquid spraying device 140 and a blowing step that operates the fan 104.

When the receiving unit 132 receives an instruction to start the mist supply course while the clothes are placed inside the drum, the mist supply course starts (S101). Once the mist supply course starts, the control unit 131 operates the lid locking mechanism to hold the lid 120 in the closed position (S102), and starts the spraying process (S104). The spraying process in S104 will be described later.

Once the spraying process in S104 is complete, the blowing process is executed (S105). During the blowing process in S105, the control unit 131 controls the motor 105 to rotate the drum 102 while simultaneously operating the fan 104 to blow air towards the clothes inside the drum 102. During the blowing process, the control unit 131 drives the fan 104 at a first rotational speed N1.

The control unit 131, after executing the air-blowing process for a predetermined time, stops the operation of the fan 104 and motor 105 to end the air-blowing process, releases the lock on the lid 120 by the lid locking mechanism (S106), and the mist supply course ends (S107).

[1-2-2. Operation in the spraying process]
The operation of the mist supply course during the spraying process will be explained below using Figures 10 to 14. Figure 10 is a flowchart of the spraying process in the mist supply course. Figures 11 to 14 are explanatory diagrams of the first to fourth examples of the operation of the liquid spraying device 140 (air pump 143), drum 102 (motor 105), and fan 104 in the mist supply course, respectively. In the following explanation, ON and OFF of the liquid spraying device 140 are synonymous with ON and OFF of the air pump 143, respectively. Also, ON and OFF of the drum 102 are synonymous with ON and OFF of the motor 105, respectively.

When the spraying process begins (S111), the control unit 131 executes the spraying process (S112).

A first example of the operation in the spraying process shown in Figure 11 will be described. In the spraying process of S112, the control unit 131 turns on the liquid spraying device 140 and sprays the liquid in the liquid tank 141 toward the clothes in the drum 102. At this time, the control unit 131 performs a tumble operation, rotating the drum 102 in both forward and reverse directions. This makes it easier for the mist sprayed by the liquid spraying device 140 to adhere uniformly to the clothes in the drum 102. The control unit 131 may stop the operation of the liquid spraying device 140 during the time when the rotation speed of the drum 102 is approximately zero while the drum 102 is being switched between forward and reverse rotation. The control unit 131 may rotate the drum 102 only in forward direction or only in reverse direction while the liquid spraying device 140 is turned on and in operation, but from the viewpoint of adhering the mist to the clothes in the drum 102, it is preferable to perform a tumble operation that rotates both forward and reverse directions. Furthermore, in the spraying process of S112, the control unit 131 may intermittently drive the liquid spraying device 140.

Furthermore, during the spraying process in S112, the control unit 131 stops the fan 104 while the liquid spraying device 140 is ON and operating. This prevents the mist supplied into the drum 102 by the liquid spraying device 140 from being disturbed by the airflow generated by the fan 104, from adhering to the inner wall of the drum 102, and from evaporating within the drum 102. It also prevents the mist from entering the airflow path 110 on the airflow generated by the fan 104 and adhering to the heater 111, etc.

Furthermore, during the spraying process in S112, the control unit 131 turns off the heater 111. This prevents the mist supplied to the drum 102 from evaporating before it adheres to the clothing.

During the spraying process, the control unit 131 determines whether the reception unit 132 has received an instruction to stop operation (S113). The instruction to stop operation may be an instruction to temporarily suspend operation, or an instruction to terminate operation.

In S113, if the control unit 131 determines that the reception unit 132 has not received a command to stop operation, that is, if the liquid spray device 140 has not received a command to stop operation from the user during the spraying process in which it is operating (NO in S113), the control unit 131 determines whether a predetermined time has elapsed since the start of the spraying process (S114). If the predetermined time has not elapsed since the start of the spraying process (NO in S114), the process returns to S113.

In S114, if a predetermined time has elapsed since the start of the spraying process, the control unit 131 stops the driving of the liquid spraying device 140 and the drum 102, terminates the spraying process (S115), and executes the standby process (S116).

Furthermore, the control unit 131 may terminate the spraying process and switch to standby mode when there is no more liquid remaining in the liquid tank 141, i.e., when the liquid tank 141 is empty. This allows the spraying process to be terminated quickly when the liquid tank 141 is empty.

In the standby process of S116, the control unit 131 turns off the liquid spray device 140, drum 102, and fan 104 for a predetermined time (for example, 2 minutes). This allows the liquid spray device 140 to spray during the spraying process, causing any remaining mist in the drum 102 to fall over time and adhere to the clothing inside the drum 102. Furthermore, the lid 120 remains closed by the lid lock during the standby process, preventing the user from opening the lid 120. This prevents the user from opening the lid 120 and inhaling the mist while it remains inside the drum 102.

Furthermore, during the standby process in S116, the reception unit 132 is configured to not accept instructions from the user to stop operation. This prevents the user from opening the lid 120 while mist remains in the drum 102. Alternatively, during the standby process in S116, the notification unit 133 may notify the user via the operation display unit 125 or a buzzer that instructions to stop operation are not being accepted.

The control unit 131 executes the standby process in S116 for a predetermined time, then terminates the standby process, ending the spraying process (S118). Afterward, the control unit 131 executes the air blowing process (S105 in Figure 9).

In S113, if the control unit 131 determines that the reception unit 132 has received an instruction to stop operation, that is, if the liquid spray device 140 receives an instruction to stop operation from the user during a spraying process in which it is operating (YES in S113), the spraying process is interrupted and a standby process is executed (S120). Note that the operation in the standby process in S120 is the same as the operation in the standby process in S116, so the explanation is omitted.

Once the standby process in S120 is complete, the control unit 131 releases the lock from the lid lock (S121), allowing the lid 120 to be opened. Then, the control unit 131 stops operation (S122).

Furthermore, if the dryer 100 is equipped with a humidity detection means for detecting the humidity of the air inside the housing 101, the control unit 131 may terminate the standby process when the humidity detected by the humidity detection means becomes below or above a predetermined humidity.

Furthermore, if the user instructs the dryer 100 to turn off the power via the operation display unit 125 during the spraying process, the control unit 131 may be configured to turn off the power while keeping the lid lock unit in operation. In this case, after the user turns the power back on, the control unit 131 may perform the spraying process, then perform a standby process before releasing the lock on the lid 120 by the lid lock unit, or the control unit 131 may not perform the spraying process, perform a standby process, and then release the lock on the lid 120 by the lid lock unit.

Next, a second example of the operation in the spraying process shown in Figure 12 will be described. As shown in Figure 12, in the second example of the operation in the spraying process, the control unit 131 turns on the fan 104 during the spraying process. At this time, the second rotational speed N2 of the fan 104 is set to a smaller rotational speed than the first rotational speed N1 of the fan 104 in the blowing process (S105). This prevents the mist supplied by the liquid spraying device 140 from adhering to the inner wall of the drum 102 due to the wind generated by the blowing means. Also, as the fan 104 rotates, an airflow is formed inside the drum 102 from rear to front. In contrast, the mist sprayed from the spray nozzle 154 is sprayed towards the lower rear inside the drum 102, so it collides with the airflow inside the drum 102 and the mist falls downwards. This allows the mist to adhere to the clothing efficiently.

Next, a third example of the operation in the spraying process shown in Figure 13 will be described. As shown in Figure 13, in this third example of the operation in the spraying process, the control unit 131 turns on the fan 104 during the standby process. At this time, the second rotational speed N2 of the fan 104 is set to a lower rotational speed than the first rotational speed N1 of the fan 104 during the blowing process (S105). This prevents the mist remaining in the drum 102 during the standby process from adhering to the inner wall of the drum 102 due to the wind generated by the blowing means.

Next, a fourth example of the operation in the spraying process shown in Figure 14 will be described. As shown in Figure 13, in the fourth example of the operation in the spraying process, during the standby process, the control unit 131 may be configured to turn off the liquid spraying device 140 and fan 104 for a predetermined time (for example, 30 seconds) and rotate the drum 102. This allows the mist remaining in the drum 102 to adhere to the clothes more quickly by tumbling them during the standby process. Therefore, rotating the drum 102 during the standby process can shorten the time required for the standby process. In this case, the control unit 131 may rotate the drum 102 only in the forward direction or only in the reverse direction, but from the viewpoint of adhering the mist to the clothes in the drum 102, it is preferable to perform a tumbling operation that includes both forward and reverse rotation.

Furthermore, in the fourth example, as shown in S120 in Figure 10, during the standby process executed when the user issues a command to stop operation, the notification unit 133 notifies the user via the operation display unit 125 and a buzzer that operation is continuing. This allows the user to recognize that the drum 102 continuing to rotate after receiving the user's command to stop operation is not a malfunction.

Furthermore, in the third and fourth examples shown in Figures 13 and 14, the rotational speed of the fan 104 during the spraying or standby process may be equal to or greater than the first rotational speed N1.

Furthermore, the first to fourth examples of operation in the mist supply course shown in Figures 11 to 14 may be rearranged or combined. Also, in the first to fourth examples, the operating periods (the periods marked as ON) of the liquid spray device 140, drum 102, and fan 104 do not necessarily have to be operated for the entire duration of the spraying and standby processes. They may be operated only for a portion of the spraying and standby processes, or they may operate intermittently.

[1-3-1. Effect 1]
As described above, in this embodiment, the dryer 100 comprises a housing 101, a drum 102 provided inside the housing 101 for containing the material to be processed, and a liquid spraying device 140 for supplying mist into the drum 102. The liquid spraying device 140 has a nozzle section 152 for spraying liquid and a base section 151 fixed to a tank cover 101c provided inside the housing 101, to which the nozzle section 152 is fixed, and the nozzle section 152 is detachably fixed to the base section 151.

This allows the user to remove the nozzle portion 152 from the base portion 151.

Therefore, the user can maintain and replace the nozzle unit 152.

As in this embodiment, the base portion 151 has an installation surface 151a for mounting the nozzle portion 152, and the base portion 151 may be detachably mounted to the tank cover 101c.

This allows the user to remove and replace the base portion 151 from the tank cover 101c.

Therefore, by replacing the base portion 151 with a base portion having a different angle of mounting surface 151a, the spray angle of the liquid by the nozzle portion 152 can be changed.

As in this embodiment, the nozzle section 152 includes a spray nozzle 154, which is a two-fluid nozzle that sprays liquid using compressed air. The liquid spraying device 140 is connected to an air pump 143 and includes an air supply path 144 through which air flowing into the spray nozzle 154 passes, a liquid supply path 142 through which liquid flowing into the spray nozzle 154 passes, and a nozzle mounting section 153 connecting the air supply path 144 and the spray nozzle 154. The nozzle mounting section 153 may have a bending structure 153a that bends the path within the nozzle mounting section 153.

This reduces the space required by the nozzle section 152, the liquid supply path 142, and the air supply path 144.

As in this embodiment, the bent structure 153a may be bent at approximately a right angle along the path within the nozzle mounting portion 153, and the liquid supply path 142 and the air supply path 144 may extend from the nozzle portion 152 in approximately the same direction.

This reduces the space required by the nozzle section 152, the liquid supply path 142, and the air supply path 144.

As in this embodiment, the dryer 100 may further include a nozzle cover 155 that sandwiches the nozzle portion 152 between itself and the base portion 151. The nozzle mounting portion 153 and the nozzle cover 155 may be sealed in the radial direction.

This results in a seal structure with high tolerance for assembly variations, ensuring stable sealing performance when the nozzle unit 150 is disassembled for replacement and then reassembled.

[1-3-2. Effect 2]
As described above, in this embodiment, the dryer 100 includes a drum 102 for containing the material to be processed, and a liquid spraying device 140 for supplying mist into the drum 102. The liquid spraying device 140 is a two-fluid nozzle and includes a spray nozzle 154 that sprays liquid using compressed air, an air pump 143 that supplies compressed air to the spray nozzle 154, an air supply path 144 connected to the air pump 143 through which the air flowing into the spray nozzle 154 passes, and a liquid supply path 142 through which the liquid flowing into the spray nozzle 154 passes.

This makes it less likely for liquid to remain inside the spray nozzle 154 after spraying by the nozzle 154 has finished.

Therefore, the liquid mixes in the spray nozzle 154, and clogging in the spray nozzle 154 can be suppressed.

As in this embodiment, the liquid spraying device 140 may further include a liquid tank 141 for storing liquid, and the spray nozzle 154 may spray the liquid contained in the liquid tank 141.

This allows the user to change the liquid contained in the liquid tank 141.

Therefore, the liquid sprayed by the spray nozzle 154 can be changed.

As in this embodiment, the spray nozzle 154 may be positioned above the liquid tank 141.

As a result, after spraying by the spray nozzle 154 is complete, the liquid returns to the liquid tank 141 by gravity through the spray nozzle 154 and the liquid supply path 142.

Therefore, since the residue of liquid in the spray nozzle 154 and the liquid supply path 142 can be suppressed, mixing of liquids in the spray nozzle 154 and the liquid supply path 142 can be suppressed.

As in this embodiment, the spray nozzle 154 may be positioned above the rotation axis X of the drum 102.

This allows the liquid to be sprayed over a wide area of the drum 102.

Therefore, localized spraying of the mist onto the workpiece contained in the drum 102 can be suppressed, allowing for efficient mist adhesion to the workpiece.

As in this embodiment, the drum 102 opens forward, the spray nozzle 154 is located in front of the drum 102, and the spray nozzle 154 may spray mist toward the lower inward side of the drum 102.

This allows the liquid to be sprayed over a wide area of the drum 102.

Therefore, localized spraying of the mist onto the workpiece contained in the drum 102 can be suppressed, allowing for efficient mist adhesion to the workpiece.

As in this embodiment, the spray nozzle 154 may be provided on the front side of the drum 102, and the spray nozzle 154 may spray mist diagonally inward from the drum 102.

This allows the liquid to be sprayed over a wide area of the drum 102.

Therefore, localized spraying of the mist onto the workpiece contained in the drum 102 can be suppressed, allowing for efficient mist adhesion to the workpiece.

[1-3-3. Effect 3]
As described above, in this embodiment, the dryer 100 includes a drum 102 for containing the material to be processed, an air passage 110 through which air flowing into the drum 102 passes, a fan 104 provided in the air passage 110 for blowing air into the drum 102, a liquid spray device 140 provided outside the air passage 110 for supplying mist into the drum 102, and a control unit 131 that enables the execution of a mist supply course that operates the liquid spray device 140. In the mist supply course, the control unit 131 drives the fan 104 to a second rotational speed N2 which is lower than the first rotational speed N1, or stops the fan 104, while the liquid spray device 140 is operating.

This allows the mist supplied by the liquid spraying device 140 to efficiently adhere to the target object while preventing it from flowing out of the drum 102 due to the airflow generated by the fan 104. Furthermore, if the drum 102 contains materials, the airflow generated by the fan 104 prevents the mist supplied by the liquid spraying device 140 from adhering to the inner wall of the drum 102 before it adheres to the materials being processed.

Therefore, the mist can be efficiently applied to the object being treated, improving the finish.

As in this embodiment, the control unit 131 may stop the fan 104 while the liquid spray device 140 is operating in the mist supply course.

This prevents the mist inside the drum 102 from being disturbed by the airflow from the fan 104, and also prevents the mist from evaporating before it can adhere to the workpiece.

Therefore, a larger amount of mist can be applied more uniformly to the object being treated, improving the finish.

As in this embodiment, the control unit 131 may operate the fan 104 after stopping the operation of the liquid spray device 140.

This allows the treated object to be dried by blowing air onto it after applying the mist.

Therefore, the final result can be improved.

As in this embodiment, the control unit 131 may set the second rotational speed N2 (the rotational speed of the fan 104 while the liquid spray device 140 is operating) to be lower than the first rotational speed N1 (the rotational speed of the fan 104 after the liquid spray device 140 has stopped operating).

This allows for a reduction in the rotation speed of the fan 104 (second rotation speed N2) while the liquid spray device 140 is operating, thereby suppressing the mist from adhering to the inner wall of the drum 102 before it can adhere to the workpiece due to the airflow. Furthermore, by increasing the rotation speed of the fan 104 (first rotation speed N1) after the liquid spray device 140 is stopped, the workpiece to which the mist has adhered can be efficiently dried.

Therefore, the mist can be efficiently applied to the object being treated, and the object with the mist applied can be dried, resulting in an improved finish.

[1-3-4. Effect 4]
As described above, in this embodiment, the dryer 100 includes a drum 102 for containing the material to be processed, a lid 120 that can open and close to cover the drum 102, a motor 105 for rotating the drum 102, a liquid spray device 140 for supplying mist into the drum 102, and a control unit 131 that enables the execution of a mist supply course for operating the liquid spray device 140. In the mist supply course, the control unit 131 stops the liquid spray device 140 and then operates the motor 105 to rotate the drum 102 for a predetermined time.

This allows the mist to adhere to the inner wall of the drum 102 through centrifugal force generated by the drum's rotation. Furthermore, if the drum 102 contains materials to be processed, the liquid spraying device 140 is operated to supply mist, and then the drum 102 is rotated to tumble the materials, thereby allowing any remaining mist inside the drum 102 to adhere to the materials.

Therefore, since the mist does not adhere to the object being processed or to the drum 102 itself within the drum 102 and remains there, it is possible to prevent the user from inhaling the mist when opening the lid 120.

As in this embodiment, the dryer 100 is equipped with a lid locking mechanism that holds the lid 120 in a closed position. The control unit 131 may, in the mist supply course, lock the lid 120 in a closed position using the lid locking mechanism, and then release the lock after a predetermined time has elapsed since stopping the liquid spraying device 140.

This prevents the lid 120 from opening while mist remains in the drum 102 after the liquid spraying device 140 has been operated and mist has been supplied.

Therefore, it is possible to prevent the user from opening the lid 120 and inhaling the mist remaining in the drum 102.

As in this embodiment, the dryer 100 is equipped with a reception unit 132 for receiving instructions from the user. The control unit 131 may, when it receives an instruction from the reception unit 132 to stop operation during the mist supply course, stop the liquid spray device 140, operate the motor 105 to rotate the drum 102 for a predetermined time, and then stop the operation of the mist supply course.

This allows the drum 102 to rotate and tumble the workpiece when a stop command is received during operation of the mist supply course, thereby allowing the mist supplied to the drum 102 to adhere to the workpiece.

Therefore, when the mist supply course is stopped and the lid 120 may be opened by the user, the amount of mist remaining in the drum 102 can be reduced, thus preventing the user from inhaling mist when opening the lid 120.

As in this embodiment, the dryer 100 is equipped with a notification unit 133. When the reception unit 132 receives an instruction to stop operation during the mist supply course, the notification unit 133 stops the liquid spray device 140 and operates the motor 105 to rotate the drum 102 for a predetermined time, while simultaneously providing a first piece of information (indicating that operation is continuing).

This allows the user to be aware that the vehicle is still running even after receiving a command to stop operation.

Therefore, after the user instructs the system to stop operation, the fact that the drum 102 is still rotating can be made to the user to understand that this is not a malfunction.

As in this embodiment, the liquid atomizing device 140 may be provided outside the airflow path 110, through which air flowing into the drum 102 passes, and a fan 104 provided in the airflow path 110 for blowing air into the drum 102.

This prevents the mist supplied by the liquid spraying device 140 from flowing out of the drum 102.

As in this embodiment, the control unit 131 may stop the liquid spray device 140 in the mist supply course, operate the motor 105 to rotate the drum 102, and then operate the fan 104.

This allows the drum 102 to rotate and tumble the workpiece before the fan 104 is activated, causing the mist remaining on the drum 102 to adhere to the workpiece, thereby suppressing the outflow of mist from the drum 102.

Therefore, it is possible to suppress the adhesion and deterioration of equipment outside the drum 102, such as the heater 111, due to mist.

As in this embodiment, the control unit 131 may set the rotation speed of the fan 104 to a second rotation speed N2 (which is less than or equal to the first rotation speed N1) or stop the fan 104 while the liquid spray device 140 is operating.

This prevents the mist supplied by the liquid spraying device 140 from flowing out of the drum 102 due to the airflow generated by the fan 104.

Therefore, it is possible to suppress the adhesion and deterioration of equipment outside the drum 102, such as the heater 111, due to mist.

As in this embodiment, the control unit 131 does not need to operate the fan 104 while the liquid spray device 140 is operating.

This prevents the mist supplied by the liquid spraying device 140 from flowing out of the drum 102 due to the airflow generated by the fan 104.

Therefore, it is possible to suppress the adhesion and deterioration of equipment outside the drum 102 due to mist.

As in this embodiment, the dryer 100 may include a liquid tank 141 for containing liquid. The liquid spraying device 140 may spray the liquid contained in the liquid tank 141.

This makes it possible to store the liquid sprayed by the liquid spraying device 140 in the liquid tank 141.

[1-3-5. Effect 5]
As described above, in this embodiment, the dryer 100 includes a drum 102 for containing the material to be processed, a lid 120 that covers the drum 102 in an openable and closable manner, a liquid spray device 140 for supplying mist into the drum 102, a control unit 131 that enables the execution of a mist supply course for operating the liquid spray device 140, and a lid locking unit that holds the lid 120 in a closed state. In the mist supply course, the control unit 131 locks the lid 120 in a closed state using the lid locking unit while the liquid spray device 140 is in operation.

As a result, since mist is present in the drum 102 while the liquid spray device 140 is operating, locking the lid 120 in the closed position prevents the user from opening the lid 120.

Therefore, it is possible to prevent the user from opening the lid 120 and inhaling the mist inside the drum 102.

As in this embodiment, the control unit 131 may, in the mist supply course, stop the liquid spray device 140 and then release the lock using the lid lock after a predetermined time has elapsed.

This prevents the user from opening the lid 120 until the mist floating inside the drum 102 has fallen to the lower part of the drum 102 or onto the object being processed, after the liquid spraying device 140 has been operated and mist has been supplied.

Therefore, it is possible to prevent the user from opening the lid 120 and inhaling the mist remaining in the drum 102.

As in this embodiment, the system includes a reception unit 132 for receiving user instructions. The control unit 131 may, when the reception unit 132 receives an instruction to stop operation during the mist supply course, stop the liquid spray device 140, and then release the lock using the lid lock unit after a predetermined time has elapsed since stopping the liquid spray device 140.

This prevents the lid 120 from opening while mist remains inside the drum 102, even when the user issues a command to stop operation.

Therefore, it is possible to prevent the user from opening the lid 120 and inhaling the mist remaining in the drum 102.

As in this embodiment, the system may be equipped with a notification unit 133. When the reception unit 132 receives an instruction to stop operation during the operation of the mist supply course, the notification unit 133 may provide first information regarding the lid 120 (that the lid 120 cannot be opened) while the lid 120 is locked by the lid lock unit.

This allows the user to understand that the cover 120 cannot be opened after receiving a command to stop operation.

Therefore, the user can be made aware that the inability to open the cover 120 after instructing the system to stop operation is not a malfunction.

(Embodiment 2)
Embodiment 2 will be described below with reference to Figure 15. In Embodiment 2, a dryer 200 will be described as the garment processing device. The dryer 200 differs from the dryer 100 in that the airflow is different. Therefore, the same aspects as in Embodiment 1, such as the configuration of the control device 130 and the liquid spray device 140, will be omitted from the explanation.

[2-1. Structure]
The dryer 200 has a drum 202 located inside the housing 101. The drum 202 is rotatably mounted inside the housing 101 with a rotation axis X extending substantially horizontally as its central axis.

A baffle 203 is provided on the inner wall of the drum 202. The baffle 203 has numerous ventilation holes 207 that connect the inside and outside of the baffle 203.

A fan 204 is provided at the rear of the housing 101 as an intake means for drawing air from inside the drum 202. When the fan 204 rotates, air from inside the drum 202 is drawn towards the fan 204 through an intake port 206 located at the rear of the drum 202. The air drawn in by the fan 204 passes through the baffle 203 and flows into the drum 202 through the air outlet 207 of the baffle 203. In this embodiment, the airflow path 210 is defined as the airflow path from the intake port 206 to the air outlet 207, from where the air is drawn in by the fan 204 to where it flows into the drum 202. The fan 204 can also be defined as an air blowing means, as it blows air drawn in from inside the drum 202 through the baffle 203 into the drum 202.

(Embodiment 3)
Embodiment 3 will be described below with reference to Figure 16. In Embodiment 3, a drum-type washer-dryer 300 will be described as the clothing processing device. The drum-type washer-dryer 300 differs in the internal configuration of the dryer 100 and the dryer 200. Therefore, the same points as in Embodiments 1 and 2, such as the configuration of the liquid spray device 140, will be omitted from the explanation.

The drum-type washer-dryer 300 comprises a water-retaining tank 301 located within the housing 101, and a drum 302 rotatably mounted within the tank 301. The peripheral wall of the drum 302 is provided with numerous water-conducting holes 302a that allow water to flow through to the tank 301. The rotation axis Y of the tank 301 and the drum 302 may be positioned to be inclined forward and upward from the horizontal, or it may be positioned to extend horizontally.

The casing 101 is equipped with a water supply valve 361 for drawing water in from the outside, a water supply path 362 for directing the water taken in from the water supply valve 361 into the water tank 301, a drain valve 363 for draining the water from the water tank 301, and a drain path 364 for discharging water to the outside when the drain valve 363 is opened. This allows the drum-type washer-dryer 300 to perform a washing operation including the washing, rinsing, and spinning cycles.

A tank cover 301c is provided on the front side of the water tank 301, covering a portion of the opening of the drum 302. The tank cover 301c may be provided on the water tank 301 or on the housing 101. In this embodiment, the nozzle unit 150 is provided on the tank cover 301c.

The drum-type washer-dryer 300 has a fan 304 that pressurizes and pumps air, an air intake 306 provided at the top of the water tank 301, and an air outlet 307 provided at the back of the water tank 301. When the fan 304 rotates, air from inside the water tank 301 is drawn in through the air intake 306, and the air drawn in by the fan 304 flows into the water tank 301 through the air outlet 307. In this embodiment, the air passage from the air intake 306 drawn in by the fan 304 to the air outlet 307 flowing into the water tank 301 is defined as the air supply path 310. The fan 304 can also be defined as an air supply means, as it blows air drawn in from inside the water tank 301 into the water tank 301 via the air supply path 310. The fan 304 is located within the air supply path 310. Air flowing into the water tank 301 from the air outlet 307 flows into the drum 302 through ventilation holes on the back of the drum 302 and flows out towards the water tank 301 through water passage holes 302a on the peripheral wall of the drum 302.

The drum-type washer-dryer 300 is equipped with a heat pump unit 311 as a heating means within the airflow path 310. The heat pump unit 311 is a device for dehumidifying and heating the air within the airflow path 310.

The drum-type washer-dryer 300 is equipped with a control device 330. The control device 330 rotates the drum 302 via the motor 105 and also controls the operation of the fan 304, heat pump unit 311, water supply valve 361, drain valve 363, and other components.

(Other embodiments)
As described above, Embodiments 1 to 3 have been explained as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited thereto and can be applied to embodiments that have been modified, replaced, added, or omitted. Furthermore, it is possible to create new embodiments by combining the components described in Embodiments 1 to 3 above.

Therefore, other embodiments are illustrated below.

In the above embodiment, a motor 105 that rotates drums 102, 202, and 302 was described as an example of a motor. The motor is not limited to a motor 105 that rotates drums 102, 202, and 302; a configuration that rotates both the storage tanks (drums 102, 202, and 302) and the fans (104, 204, and 304) is also possible.

In the above embodiment, a liquid atomizing device 140 having an air pump 143 and a spray nozzle 154, which is a two-fluid nozzle, was described as an example of a mist supply means. The mist supply means is not limited to the liquid atomizing device 140, as it only needs to spray mist. The mist supply means may also be a liquid transfer pump or an ultrasonic oscillator.

In the above embodiment, a nozzle mounting section 153 connecting the air supply path 144 and the spray nozzle 154 was described as an example of a nozzle mounting section. Since the nozzle mounting section only needs to connect the fluid passage and the spray nozzle (spray nozzle 154), it may also be provided to connect the liquid supply path (liquid supply path 142) and the spray nozzle (spray nozzle 154).

In the above embodiment, as an example of a bending structure for bending the path of the nozzle mounting portion 153, a bending structure 153a was described in which the path within the nozzle mounting portion 153 is bent at a right angle. The bending structure is not limited to the bending structure 153a provided in the nozzle mounting portion 153, as it only needs to bend the path through which the fluid flowing into the spray nozzle passes. If the liquid supply path or air supply path is directly attached to the spray nozzle, the bending structure may directly bend the liquid supply path or air supply path. Furthermore, the bending structure only needs to bend the path within the nozzle mounting portion by 1 to 90 degrees. In the case of a two-fluid nozzle used as the spray nozzle, where the air-side connection portion connected to the air supply path and the liquid-side connection portion connected to the liquid supply path are provided vertically, if the bending structure bends the path through which the fluid flowing into the spray nozzle passes by 90 degrees, space saving in the space provided for the nozzle portion, air supply path, and liquid supply path can be achieved.

In the above embodiment, as an example of a first course for operating the mist supply device, a mist supply course was described in which the liquid spray device 140 is operated with the contents to be contained. The first course is not limited to a mist supply course, as it can be any course in which the mist supply device is operated. The first course may consist only of a spraying process. In this case as well, the rotation speed of the fan in the spraying process may be lower than the rotation speed of the fan in the blowing process, or lower than the rotation speed of the fan in other courses that dry the contents to be processed. Furthermore, the first course may be a tub care course in which the mist supply device is operated with no clothes contained in the storage tubs (drums 102, 202, 302) to adhere mist to the tubs (drums 102, 202, 302, water tub 301). Also, if the clothing processing device is capable of washing the contents to be contained, the first course may perform the spraying process after performing at least one of the washing, rinsing, and dewatering processes. Furthermore, the first course may also be configured to perform a blowing process that drives the blowing means before and/or after the spraying process, and may also include a process of operating the heating means during the execution of the blowing process.

In the above embodiment, a liquid tank 141, which can be removed from the housing 101 and refilled, was described as an example of a liquid tank for containing liquid. The liquid tank is not limited to the liquid tank 141, as it only needs to contain the liquid sprayed by the mist supply means. The liquid tank may also be a cartridge in which the liquid contained inside cannot be refilled.

In the above embodiment, as an example of a spray nozzle, a spray nozzle 154 provided above the rotation axis X of the liquid tank 141 and drum 102 was described. Since the spray nozzle only needs to spray the liquid contained in the liquid tank, its position is not limited. If the spray nozzle is provided below the liquid tank, the liquid supplied from the liquid tank to the spray nozzle is less affected by the head, making it possible to reduce the output of the air pump or liquid transfer pump. Similarly, if the spray nozzle is located below the center of the storage tank, the liquid supplied from the liquid tank to the spray nozzle is less affected by the head, making it possible to reduce the output of the air pump or liquid transfer pump.

In the above embodiment, a liquid spray device 140, located outside the airflow path 110 (airflow path 210, airflow path 310), was described as an example of a mist supply means. The mist supply means is not limited to the liquid spray device 140, as it only needs to supply mist into the containment tank. The mist supply means may be located within the airflow path, or an airflow means may be provided near the spray nozzle of the liquid spray device to deliver mist into the containment tank.

In the above embodiments, tank cover 101c (Embodiment 1) and tank cover 301c (Embodiment 3) were described as examples of the first member to which the nozzle unit is fixed. The nozzle unit is not limited to tank cover 101c and tank cover 301c, as it only needs to be mounted in a way that allows mist to be supplied into the storage tanks (drums 102, 202, 302). The first member may be a lid (lid 120), a part of a housing (housing 101), or a part of a water tank (water tank 301) or storage tanks (drums 102, 202, 302).

In Embodiment 1, a heater 111 that heats the air in the airflow path 110 was described as an example of a heating means. The heating means is not limited to the heater 111, as it only needs to heat the air in the airflow path. The heating means may also be a heat pump unit that dehumidifies and heats the air in the airflow path, as described in Embodiment 3.

This disclosure is applicable to garment processing equipment that includes a mist supply device for spraying mist and processes items to be processed. Specifically, it is applicable to garment processing equipment including drum-type washing machines, top-loading washing machines, drum-type washer-dryers, top-loading washer-dryers, clothes dryers, and closet-type garment care machines with non-rotating tubs.
