[0028] (Insights, etc. that form the basis of the present disclosure)

[0029] Until the inventors came up with the present disclosure, there had been drum-type washing and drying machines that supply mist to washed items after drying. Such drum-type washing and drying machines are equipped with a mist generating device that generates mist by applying ultrasonic vibration to water stored in a water storage container. Based on such a situation, the inventors came up with the following idea: to effectively treat the object to be treated, such as clothing, and the tank by spraying a liquid agent in the form of mist onto the object to be treated, such as clothing, and the tank, using a mist supply component that sprays the liquid agent in the form of mist. However, when the liquid agent is sprayed by the mist supply component, the inventors found that there are multiple problems.

[0030] The first problem is that when the liquid agent is sprayed by the mist supply component, it is necessary to reduce the risk of the user inhaling the mist. Especially when using a two-fluid nozzle as the spray nozzle of the mist supply component, small-sized mist is sprayed. When spraying large-sized mist, since the weight of the mist is heavy, the mist will immediately fall and it is difficult to evenly adhere to the spraying object. When spraying small-sized mist, the floating time of the mist is long and it can evenly adhere to the spraying object. However, if the user opens the lid when small-sized mist of the liquid agent remains in the receiving tank, the user may inhale the mist. Different from the situation of spraying water in the mist generating device in the prior art, when spraying the liquid agent, it is necessary to prevent the user from inhaling the mist.

[0031] The second problem is that it is necessary to prevent clogging of the liquid agent in the mist supply component. For example, the user can change the liquid agent stored in the liquid tank. When the mist supply component sprays the liquid agent stored in the liquid tank, after changing the liquid agent, an attachment is generated by mixing the liquid agents in the mist supply component, which may cause clogging of the liquid agent. In addition, when clogging of the liquid agent occurs in the mist supply component, it is necessary to replace or maintain a part of the mist supply component.

[0032] The inventors found the problems as described above, and to solve this problem, the subject matter of the present disclosure was constituted.

[0033] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, unnecessary details may sometimes be omitted. For example, details of well-known matters may sometimes be omitted, or details of substantially the same structures may be omitted. This is to avoid making the following description too lengthy and to make it easy for those skilled in the art to understand.

[0034] In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter recited in the claims by them.

[0035] (Embodiment 1)

[0036] Hereinafter, use Figures 1 to 14To describe Embodiment 1. In addition, in Embodiment 1, as an example of a laundry treatment device, a dryer 100 will be described.

[0037] [1-1. Structure]

[0038] [1-1-1. Structure of the dryer]

[0039] Use Figure 1 And Figure 2 To describe the structure of the dryer 100. Figure 1 Is a front view of the dryer 100. Figure 2 Is a longitudinal sectional view of the main part of the dryer 100.

[0040] The dryer 100 includes a housing 101, a drum 102, a lid 120, and an operation display unit 125. The housing 101 includes a front plate 101a that constitutes the front surface side of the dryer 100 and a tank lid 101b provided at the lower part of the front surface of the housing 101.

[0041] The drum 102 is provided inside the housing 101. The drum 102 is provided inside the housing 101 so as to be rotatable about a rotation axis X extending in a substantially horizontal direction. The drum 102 is formed in a bottomed cylindrical shape having a drum opening 102a on the front surface side, and the object to be processed is accommodated therein. Examples of the object to be processed accommodated in the drum 102 include clothes, shoes, bags, hats, etc. In addition, an example of accommodating clothes as the object to be processed in the drum 102 will be described in the present embodiment below.

[0042] A motor 105 is disposed at the lower rear side inside the housing 101. The motor 105 drives the drum 102 to rotate.

[0043] The lid 120 is attached to the front plate 101a and covers the drum opening 102a in an openable and closable manner. The user opens the lid 120 and puts the object to be processed into the drum 102 through the drum opening 102a. In addition, the dryer 100 includes a lid locking portion. The lid locking portion can hold the lid 120 in a closed state.

[0044] A trough lid 101c that covers a part of the drum opening 102a is provided inside the housing 101 (illustrated in Figure 2 , Figure 6 And Figure 7 ). When the dryer 100 is viewed from the front, the trough lid 101c covers the part of the drum opening 102a that is closer to the outer peripheral side than the lid 120. In addition, the trough lid 101c may be provided continuously with the front plate 101a or may be provided as a different member.

[0045] On the inner wall of the drum 102, there is a projection (baffle) 103. When the drum 102 rotates, the projection 103 lifts the objects accommodated in the drum 102.

[0046] At the front part inside the housing 101, there is an air suction port 106 for sucking air inside the drum 102. Additionally, at the rear part inside the housing 101, there is a fan 104 as a blowing component for sending air into the drum 102. The fan 104 is arranged outside the drum 102. When the fan 104 rotates, it sucks air from the air suction port 106 and sends the air into the drum 102 through the air outlet 107 provided at the rear of the drum 102. In this embodiment, the air passage from the air suction port 106 until the air is sucked and flows into the drum 102 through the air outlet 107 is defined as the air blowing path 110. The fan 104 is arranged in the air blowing path 110. In the air blowing path 110, there is a heater 111 for heating the air passing through the air blowing path 110.

[0047] At the upper part of the front surface of the housing 101, there is an operation display unit 125. The operation display unit 125 is configured to not only receive operation instructions from the user but also be able to display the operation status of the dryer 100 and the like.

[0048] At the lower inner part of the housing 101, there is a control device 130. The control device 130 controls the operations of the fan 104, the motor 105, the heater 111, etc. The structure of the control device 130 will be described later.

[0049] [1-1-2. Structure of the liquid spraying device]

[0050] Inside the housing 101, there is a liquid spraying device 140 for supplying mist into the drum 102. Next, Figure 3 and Figure 4 will be used to describe the liquid spraying device 140. Figure 3 is a schematic diagram showing the main structure of the liquid spraying device 140. Figure 4 is a longitudinal sectional view of the dryer 100 including the liquid spraying device 140.

[0051] The liquid spraying device 140 is arranged outside the air blowing path 110. The liquid spraying 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).

[0052] The liquid tank 141 is configured to store liquid. Examples of the liquid accommodated in the liquid tank 141 include liquid agents such as wrinkle removers, germicides, deodorants, air fresheners, insect repellents, pre-cleaning agents, waterproofing agents, and stain repellents. In addition, water may also be accommodated in the liquid tank 141. The liquid tank 141 is provided at the lower inner part of the housing 101. By opening the tank lid 101b and taking out the liquid tank 141 from inside the housing 101, the user can change, refill, and supplement the liquid accommodated in the liquid tank 141. In addition, the position where the tank lid 101b is provided is not limited to the lower front surface of the housing 101 as long as it is a position where the user can take out the liquid tank 141, and it can be determined according to the arrangement position of the liquid tank 141.

[0053] The liquid supply path 142 is a path for supplying the liquid accommodated in the liquid tank 141 to the spray nozzle 154. In other words, the liquid supply path 142 is a path through which the liquid flowing into the spray nozzle 154 passes.

[0054] The air pump 143 is a device for supplying compressed air to the spray nozzle 154.

[0055] The air supply path 144 is connected to the air pump 143. The air supply path 144 is a path through which the air flowing into the spray nozzle 154 passes.

[0056] As Figure 4 shown, the nozzle unit 150 is provided at a position above the liquid tank 141. Thus, when the liquid spraying device 140 stops operating, the liquid in the liquid supply path 142 returns toward the liquid tank 141, so that the liquid remaining in the liquid supply path 142 can be suppressed. In addition, preferably, in order to prevent the liquid from remaining in the liquid supply path 142, the liquid supply path 142 is preferably arranged to be gradually located above as it goes from the liquid tank 141 to the nozzle unit 150.

[0057] In addition, in the present embodiment, the liquid supply path 142 and the air supply path 144 are formed of rubber hoses, but the materials and methods for forming the liquid supply path 142 and the air supply path 144 are not limited.

[0058] [1-1-3. Structure of the Nozzle Unit]

[0059] Use Figures 5 to 7 to illustrate the structure of the nozzle unit 150. Figure 5 is an exploded perspective view of the nozzle unit 150. Figure 6 is a cross-sectional view obtained by observing the front from the middle in the front-rear direction of the dryer 100. Figure 7 is Figure 6 a partial enlarged view of

[0060] The nozzle unit 150 includes a base portion 151, a nozzle portion 152, and a nozzle cap 155.

[0061] The base portion 151 is a member for mounting the nozzle unit 150 to the tank lid 101c, and is detachably provided to the tank lid 101c. The base portion 151 is fixed to the tank lid 101c by screw fastening. In the present embodiment, the base portion 151 is screw-fastened to the inner back surface of the tank lid 101c from the inside of the tank lid 101c.

[0062] The nozzle portion 152 includes a nozzle mounting portion 153 and a spray nozzle 154. In a state where the spray nozzle 154 is mounted to the nozzle mounting portion 153, the nozzle portion 152 is fixed to the mounting surface 151a of the base portion 151 by screw fastening. In addition, the nozzle mounting portion 153 is detachably provided to the mounting surface 151a of the base portion 151. That is, the nozzle portion 152 is detachably provided to the base portion 151.

[0063] The nozzle mounting portion 153 is connected between the air supply path 144 and the air-side connection portion 154a (described later) of the spray nozzle 154. In addition, an O-ring for suppressing air leakage may be provided at the connection portion between the air supply path 144 and the nozzle mounting portion 153.

[0064] The spray nozzle 154 is a two-fluid nozzle that sprays a liquid using compressed air. The spray nozzle 154 includes an air-side connection portion 154a, a liquid-side connection portion 154b, and a spray port 154c. The air-side connection portion 154a is connected to the nozzle mounting portion 153, and causes the air that has passed through the air supply path 144 to flow into the spray nozzle 154. The liquid-side connection portion 154b is connected to the liquid supply path 142, and causes the 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 portion 154a to spray the liquid flowing in from the liquid-side connection portion 154b.

[0065] The air-side connection portion 154a and the spray port 154c are provided on substantially a straight line, and the air-side connection portion 154a is provided substantially orthogonally to the liquid-side connection portion 154b. In addition, an O-ring for suppressing air leakage may be provided at the connection portion between the air-side connection portion 154a and the nozzle mounting portion 153. Further, an O-ring for suppressing liquid leakage may be provided at the connection portion between the liquid-side connection portion 154b and the liquid supply path 142.

[0066] The nozzle part 152 is sandwiched between the base part 151 and the nozzle cap 155 in a state where the spray nozzle 154 is attached to the nozzle attachment part 153, and is threadedly fastened to the nozzle cap 155 through the screw hole provided in the setting surface 151a and the screw hole provided in the nozzle attachment part 153, whereby it is fixed to the base part 151. In other words, the nozzle cap 155 fixes the nozzle part 152 to the base part 151. In addition, the nozzle attachment part 153 and the nozzle cap 155 are sealed in the radial direction. Regarding the sealing in the radial direction, since the tolerance for assembly deviation is large, the sealing performance can be stably ensured when disassembling and reassembling for replacing the nozzle unit 150.

[0067] The base part 151 is detachably provided on the trough cover 101c. Alternatively, a plurality of base parts 151 may be provided, and different base parts 151 have setting surfaces 151a at different angles. Thus, by replacing and installing the base part 151 on the trough cover 101c, the setting angle of the nozzle part 152 can be changed. Therefore, the angle of the spray port 154c can be changed, and thus the angle of the mist ejected from the spray nozzle 154 can be changed according to the type of the liquid stored in the liquid tank 141 and the usage purpose of the liquid spraying device 140.

[0068] The nozzle attachment part 153 is connected to the air supply path 144 in a substantially vertical direction and to the air-side connection part 154a of the spray nozzle 154 in a substantially horizontal direction. That is to say, the nozzle attachment part 153 has a bending structure 153a that bends the path inside the nozzle attachment part 153 at a substantially right angle. In other words, the bending structure 153a bends the path through which the air flowing into the spray nozzle 154 passes. Thereby, the space required for the nozzle part 152, which is the front-rear direction in this embodiment, can be reduced. And due to the bending structure 153a, the liquid supply path 142 and the air supply path 144 are arranged to extend in substantially the same direction, which is to extend substantially vertically downward from the nozzle part 152 in this embodiment. Thereby, the space required for the nozzle part 152, which is the front-rear direction in this embodiment, can be suppressed, and thus the space for setting the nozzle part 152 can be saved. In addition, since the liquid-side connection part 153b of the spray nozzle 154 and the nozzle attachment part 153 can connect the liquid supply path 142 and the air supply path 144 from the same direction, the nozzle part 152, the liquid supply path 142, and the air supply path 144 can be easily replaced.

[0069] As Figure 6 and Figure 7As shown, the spray nozzle 154 is provided at the upper right portion (when viewed from the front) of the tank lid 101c. That is to say, the spray nozzle 154 is provided at the upper front side portion of the drum 102. The spray nozzle 154 sprays mist in the diagonal direction of the drum 102, that is, the lower left portion (when viewed from the front) of the inner rear portion of the drum 102. The mist ejected from the spray nozzle 154 falls downward due to gravity. Therefore, by providing the spray nozzle 154 at the upper front portion of the drum 102, it is possible to suppress the local adhesion of the mist to the clothes housed in the drum 102 and to make the mist adhere over a wide range.

[0070] [1-1-4. Structure of the control device]

[0071] Use Figure 8 to illustrate the structure of the control device 130. Figure 8 is a block diagram of the control device 130.

[0072] The control device 130 includes a control unit 131, a reception unit 132, and a notification unit 133.

[0073] The control unit 131 controls the operations of the fan 104, the motor 105, the heater 111, the air pump 143, and the lid locking unit.

[0074] The reception unit 132 receives the instructions input by the user through the operation display unit 125. The control unit 131 controls the operations of the above-mentioned various devices according to the instructions such as the operation program received by the reception unit 132.

[0075] The notification unit 133 notifies the user of the operation status of the dryer 100 through the operation display unit 125 and the buzzer.

[0076] In addition, when the dryer 100 is provided with a communication unit capable of communicating with an external terminal, it may be set such that the reception unit 132 can receive the instructions input by the user through the external terminal from the communication unit. Alternatively, it may be set such that the notification unit 133 can notify the user of the operation status of the dryer 100 through the communication unit on the external terminal.

[0077] [1-2. Operations, etc.]

[0078] Next, the operations and functions of the dryer 100 configured as described above will be described.

[0079] [1-2-1. Operations in the mist supply program]

[0080] The control unit 131 can execute a mist supply program for controlling the air pump 143 to operate the liquid spraying device 140. The mist supply program is a program for operating the liquid spraying device 140 in a state where clothes are housed in the drum 102. Next, the control and operations in the mist supply program will be described with reference to the drawings.Figure 9 This is a flowchart of the mist supply program.

[0081] The mist supply program includes a spraying process that operates the liquid spraying device 140 and a blowing process that operates the fan 104.

[0082] When the receiving unit 132 receives an instruction to start the mist supply program while there are clothes accommodated in the drum, the mist supply program starts (S101). When the mist supply program starts, the control unit 131 operates the lid locking unit to keep the lid 120 in the closed state (S102), and starts the spraying process (S104). The spraying process of S104 will be described later.

[0083] When the spraying process of S104 ends, the blowing process is executed (S105). In the blowing process of S105, the control unit 131 operates the fan 104 to blow air toward the clothes in the drum 102 while controlling the motor 105 to rotate the drum 102. The control unit 131 drives the fan 104 at the first rotation speed N1 in the blowing process.

[0084] When the control unit 131 executes the blowing process for a specified time, it stops the operations of the fan 104 and the motor 105 to end the blowing process, releases the locking of the lid 120 by the lid locking unit (S106), and the mist supply program ends (S107).

[0085] [1-2-2. Actions in the spraying process]

[0086] Next, the actions in the spraying process of the mist supply program will be described using Figures 10 to 14 This is a flowchart of the spraying process of the mist supply program. Figure 10 Figures 11 to 14 Figures 11 to 14 These are explanatory diagrams of the first to fourth examples of the operations of the liquid spraying device 140 (air pump 143), the drum 102 (motor 105), and the fan 104 in the mist supply program. In addition, in the following description, the opening (ON) and closing (OFF) of the liquid spraying device 140 are synonymous with the opening and closing of the air pump 143, respectively. Also, the opening and closing of the drum 102 are synonymous with the opening and closing of the motor 105, respectively.

[0087] When the spraying process starts (S111), the control unit 131 executes the spraying process (S112).

[0088] Regarding Figure 11A first example of the operation in the spraying process shown will be described. In the spraying process of S112, the control unit 131 turns on the liquid spraying device 140 to spray the liquid in the liquid tank 141 onto the clothes in the drum 102. At this time, the control unit 131 performs a tumbling operation that rotates the drum 102 forward and backward. Thereby, it is possible to easily make the mist sprayed by the liquid spraying device 140 uniformly adhere to the clothes in the drum 102. In addition, 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 0 during the period when the drum 102 is switched between forward rotation and reverse rotation. In addition, the control unit 131 may rotate the drum 102 only in the forward rotation mode or only in the reverse rotation mode during the period when the liquid spraying device 140 is turned on and operating, but from the viewpoint of making the mist adhere to the clothes in the drum 102, it is preferable to perform the forward and reverse tumbling operations. In addition, in the spraying process of S112, the control unit 131 may intermittently drive the liquid spraying device 140.

[0089] In addition, in the spraying process of S112, the control unit 131 stops the fan 104 during the period when the liquid spraying device 140 is turned on and operating. Thereby, it is possible to suppress the mist supplied to the drum 102 by the liquid spraying device 140 from being disturbed by the wind generated by the fan 104 and adhering to the inner wall of the drum 102, and to suppress the evaporation of the mist in the drum 102. In addition, it is possible to suppress the mist from entering the air supply path 110 by the wind generated by the fan 104 and adhering to the heater 111 or the like.

[0090] In addition, in the spraying process of S112, the control unit 131 turns off the heater 111. Thereby, it is possible to suppress the evaporation of the mist supplied to the drum 102 before it adheres to the clothes.

[0091] In the spraying process, the control unit 131 determines whether the receiving unit 132 has received an instruction to stop the operation (S113). The instruction to stop the operation may be an instruction to temporarily stop the operation or an instruction to end the operation.

[0092] When the control unit 131 determines in S113 that the receiving unit 132 has not received an instruction to stop the operation, that is, when no instruction to stop the operation is received from the user during the spraying process in which the liquid spraying device 140 is operating (in S113, it is "no"), the control unit 131 determines whether a predetermined time has elapsed after the start of the spraying process (S114). When the predetermined time has not elapsed after the start of the spraying process (in S114, it is "no"), the process returns to S113.

[0093] In S114, when a predetermined time has elapsed after the start of the spraying process, the control unit 131 stops driving the liquid spraying device 140 and the drum 102 to end the spraying process (S115), and executes a standby process (S116).

[0094] In addition, the control unit 131 may also end the spraying process and transfer to the standby process when there is no remaining liquid in the liquid tank 141, that is, when the liquid tank 141 becomes empty. Thus, the spraying process can be ended in a short time when the liquid tank 141 is empty.

[0095] In the standby process of S116, the control unit 131 makes the liquid spraying device 140, the drum 102, and the fan 104 turn off and standby for a predetermined time (for example, 2 minutes). Thus, the mist sprayed by the liquid spraying device 140 during the spraying process and remaining in the drum 102 can fall over time and adhere to the clothes in the drum 102. In addition, during the standby process, the lid 120 is also held in the closed state by the lid locking unit, so the user cannot open the lid 120. Thus, it is possible to prevent the user from opening the lid 120 and inhaling the mist when there is still mist remaining in the drum 102.

[0096] In addition, in the standby process of S116, it is set that the reception unit 132 does not accept an instruction to stop the operation from the user. Thus, it is possible to prevent the user from being able to open the lid 120 when there is still mist remaining in the drum 102. In addition, in the standby process of S116, the notification unit 133 may also notify the meaning of not accepting the instruction to stop the operation through the operation display unit 125 and the buzzer.

[0097] When the control unit 131 executes the standby process of S116 for a predetermined time, it ends the standby process and ends the spraying process (S118). After that, the control unit 131 executes the air supply process ( Figure 9 of S105).

[0098] In the case where the control unit 131 determines in S113 that the reception unit 132 has received an instruction to stop the operation, that is, when an instruction to stop the operation is received from the user during the spraying process in which the liquid spraying device 140 is operating (in S113, it is "Yes"), the spraying process is interrupted and a standby process is executed (S120). In addition, the operation in the standby process of S120 is the same as the operation in the standby process of S116, so the description is omitted.

[0099] When the standby process of S120 ends, the control unit 131 releases the locking by the lid locking unit (S121), and the lid 120 becomes in a state where it can be opened. Then, the control unit 131 stops the operation (S122).

[0100] In addition, when the dryer 100 is provided with a humidity detection component for detecting the humidity in the air inside the housing 101, the control unit 131 may also end the standby process when the humidity detected by the humidity detection component is below or above a specified humidity.

[0101] Alternatively, the following structure may be adopted: when the user gives an instruction to cut off the power supply of the dryer 100 by operating the display unit 125 during the spraying process, the control unit 131 cuts off (turns off) the power supply while keeping the lid locking unit in operation. In this case, it may also be that after the user turns on (turns on) the power supply again, the control unit 131 executes the spraying process, and then, after executing the standby process, releases the locking of the lid 120 by the lid locking unit. It may also be that the control unit 131 does not execute the spraying process but releases the locking of the lid 120 by the lid locking unit after executing the standby process.

[0102] Next, Figure 12 A second example of the operation in the spraying process shown in Figure 12 will be described. As shown in

[0103] Next, Figure 13 A third example of the operation in the spraying process shown in Figure 13 will be described. As shown in

[0104] Next, Figure 14 A fourth example of the operation in the spraying process shown in Figure 13As shown, in the fourth example of the operations in the spraying process, the structure may also be as follows: during the standby process, the control unit 131 turns off the liquid spraying device 140 and the fan 104 for a specified time (e.g., 30 seconds) and rotates the drum 102. Thereby, by tumbling the laundry during the standby process, the mist remaining in the drum 102 can be made to adhere to the laundry in the drum 102 more quickly. Therefore, when the drum 102 is rotated during the standby process, the time required for the standby process can be shortened. Further, in this case, the control unit 131 may also rotate the drum 102 only in the forward rotation mode or only in the reverse rotation mode, but from the viewpoint of making the mist adhere to the laundry in the drum 102, it is preferable to perform the tumbling actions of forward rotation and reverse rotation.

[0105] In addition, in the fourth example, in the standby process performed when an instruction to stop the operation by the user is received as in Figure 10 S120, the notification unit 133 notifies the meaning that the operation is continuing through the operation display unit 125 and the buzzer. Thereby, the user can recognize that the rotation of the drum 102 after receiving the instruction to stop the operation by the user is not a malfunction.

[0106] In addition, in Figure 13 and Figure 14 the third and fourth examples shown, the rotational speed of the fan 104 during the spraying process or the standby process may be set to the same rotational speed as the first rotational speed N1, or may be set to a rotational speed higher than the first rotational speed N1.

[0107] In addition, Figures 11 to 14 the first to fourth examples of the operations in the mist supply program shown may be reorganized separately or may be combined. Further, regarding the operation periods (the periods during which they are turned on) of the liquid spraying device 140, the drum 102, and the fan 104 in the first to fourth examples, they may not operate during the entire period of the spraying process and the standby process, or may operate only during a part of the spraying process and the standby process, or may operate intermittently.

[0108] [1-3. Effects, etc.]

[0109] [1-3-1. Effect 1]

[0110] As described above, in the present embodiment, the dryer 100 includes: a housing 101; a drum 102 disposed within the housing 101 for accommodating an object to be processed; and a liquid spraying device 140 that supplies mist into the drum 102. The liquid spraying device 140 has: a nozzle portion 152 that sprays a liquid; and a base portion 151 that is fixed to a trough cover 101c provided within the housing 101 for fixing the nozzle portion 152, wherein the nozzle portion 152 is detachably fixed to the base portion 151.

[0111] Accordingly, the user can remove the nozzle portion 152 from the base portion 151.

[0112] Therefore, the user can perform maintenance and replacement on the nozzle portion 152.

[0113] As in the present embodiment, it may also be that the base portion 151 has a setting surface 151a for setting the nozzle portion 152, and the base portion 151 is detachably provided on the trough cover 101c.

[0114] Accordingly, the user can remove the base portion 151 from the trough cover 101c for replacement.

[0115] Therefore, by replacing the base portion 151 with a base portion having a different set angle of the setting surface 151a, the angle at which the liquid is sprayed by the nozzle portion 152 can be changed.

[0116] As in the present embodiment, it may also be that the nozzle portion 152 includes a two-fluid nozzle, i.e., a spray nozzle 154, that sprays a liquid using compressed air, and the liquid spraying device 140 includes: an air supply path 144 that is connected to an air pump 143 and 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 portion 153 that is connected between the air supply path 144 and the spray nozzle 154, wherein the nozzle mounting portion 153 has a bending structure 153a that bends the path within the nozzle mounting portion 153.

[0117] Accordingly, the space required for the nozzle portion 152, the liquid supply path 142, and the air supply path 144 can be reduced.

[0118] As in the present embodiment, it may also be that the bending structure 153a bends the path within the nozzle mounting portion 153 into a substantially right angle, and the liquid supply path 142 and the air supply path 144 extend in substantially the same direction from the nozzle portion 152.

[0119] Accordingly, the space required for the nozzle portion 152, the liquid supply path 142, and the air supply path 144 can be reduced.

[0120] As in this embodiment, the dryer 100 may further include a nozzle cap 155 that clamps the nozzle portion 152 between the base portion 151. The nozzle mounting portion 153 and the nozzle cap 155 may also be sealed in the radial direction.

[0121] Accordingly, a sealing structure with a large tolerance for assembly deviation can be obtained, and the sealing performance can be stably ensured when disassembling and reassembling for replacing the nozzle unit 150.

[0122] [1-3-2. Effect 2]

[0123] As described above, in this embodiment, the dryer 100 includes a drum 102 that houses an object to be processed and a liquid spraying device 140 that supplies mist into the drum 102. The liquid spraying device 140 includes: a spray nozzle 154, which is a two-fluid nozzle and sprays a liquid using compressed air; an air pump 143 that supplies compressed air to the spray nozzle 154; an air supply path 144 that is connected to the air pump 143 and through which air flowing into the spray nozzle 154 passes; and a liquid supply path 142 through which liquid flowing into the spray nozzle 154 passes.

[0124] Accordingly, after spraying by the spray nozzle 154 is completed, it is difficult for liquid to remain in the spray nozzle 154.

[0125] Therefore, it is possible to suppress liquid mixing in the spray nozzle 154 and clogging of the spray nozzle 154.

[0126] As in this embodiment, the liquid spraying device 140 may further include a liquid tank 141 for storing liquid, and the spray nozzle 154 sprays the liquid housed in the liquid tank 141.

[0127] Accordingly, the user can change the liquid housed in the liquid tank 141.

[0128] Therefore, it is possible to change the liquid sprayed by the spray nozzle 154.

[0129] As in this embodiment, the spray nozzle 154 may be provided at a position above the liquid tank 141.

[0130] Accordingly, after spraying by the spray nozzle 154 is completed, the liquid returns to the liquid tank 141 due to its own weight in the spray nozzle 154 and the liquid supply path 142.

[0131] Therefore, it is possible to suppress the remaining of liquid in the spray nozzle 154 and the liquid supply path 142, and thus it is possible to suppress the mixing of liquid in the spray nozzle 154 and the liquid supply path 142.

[0132] As in the present embodiment, the spray nozzle 154 may be provided at a position above the rotation axis X of the drum 102.

[0133] Thereby, the liquid can be sprayed over a wide range of the drum 102.

[0134] Therefore, it is possible to suppress local spraying onto the object to be processed accommodated in the drum 102, and the mist can be efficiently attached to the object to be processed.

[0135] As in the present embodiment, the drum 102 may be open forward, the spray nozzle 154 may be provided in front of the drum 102, and the spray nozzle 154 may spray mist toward the lower inner side of the drum 102.

[0136] Thereby, the liquid can be sprayed over a wide range of the drum 102.

[0137] Therefore, it is possible to suppress local spraying onto the object to be processed accommodated in the drum 102, and the mist can be efficiently attached to the object to be processed.

[0138] As in the present embodiment, the spray nozzle 154 may be provided on the front side portion of the drum 102, and the spray nozzle 154 may spray mist toward the diagonal direction inside the drum 102.

[0139] Thereby, the liquid can be sprayed over a wide range of the drum 102.

[0140] Therefore, it is possible to suppress local spraying onto the object to be processed accommodated in the drum 102, and the mist can be efficiently attached to the object to be processed.

[0141] [1-3-3. Effect 3]

[0142] As described above, in the present embodiment, the dryer 100 includes: a drum 102 that accommodates an object to be processed; an air supply path 110 through which air flowing into the drum 102 passes; a fan 104 provided in the air supply path 110 that blows air into the drum 102; a liquid spraying device 140 provided outside the air supply path 110 that supplies mist into the drum 102; and a control unit 131 that can execute a mist supply program for operating the liquid spraying device 140. During the mist supply program, the control unit 131 drives the fan 104 at a second rotational speed N2 that is lower than the first rotational speed N1 or stops the fan 104 while operating the liquid spraying device 140.

[0143] Accordingly, it is possible to suppress the outflow of the mist supplied by the liquid spraying device 140 to the outside of the drum 102 due to the wind generated by the fan 104, and it is possible to efficiently attach the mist to the object to be sprayed. In addition, when the container is accommodated in the drum 102, it is possible to suppress 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 fan 104 before adhering to the object to be processed.

[0144] Therefore, it is possible to efficiently attach the mist to the object to be processed and improve the finishing effect.

[0145] As in the present embodiment, the control unit 131 may stop the fan 104 during the period when the liquid spraying device 140 is operating in the mist supply program.

[0146] Accordingly, it is possible to suppress the disturbance of the mist in the drum 102 by the wind generated by the fan 104 and suppress the evaporation of the mist before it adheres to the object to be processed.

[0147] Therefore, it is possible to attach a large amount of mist more uniformly to the object to be processed and improve the finishing effect.

[0148] As in the present embodiment, the control unit 131 may operate the fan 104 after stopping the operation of the liquid spraying device 140.

[0149] Accordingly, by blowing air on the object to be processed to which the mist adheres, it is possible to dry the object to be processed.

[0150] Therefore, the finishing effect can be improved.

[0151] As in the present embodiment, the control unit 131 may make the second rotation speed N2 less than the first rotation speed N1, where the second rotation speed N2 is the rotation speed of the fan 104 during the period when the liquid spraying device 140 is operating, and the first rotation speed N1 is the rotation speed of the fan 104 after stopping the operation of the liquid spraying device 140.

[0152] Accordingly, by reducing the rotation speed (second rotation speed N2) of the fan 104 during the period when the liquid spraying device 140 is operating, it is possible to suppress the mist from adhering to the inner wall of the drum 102 due to the wind before adhering to the object to be processed, and it is possible to efficiently dry the object to be processed to which the mist adheres by increasing the rotation speed (first rotation speed N1) of the fan 104 after stopping the operation of the liquid spraying device 140.

[0153] Therefore, it is possible to efficiently attach the mist to the object to be processed and dry the object to which the mist adheres, and thus the finishing effect can be improved.

[0154] [1-3-4. Effect 4]

[0155] As described above, in the present embodiment, the dryer 100 includes: a drum 102 that houses an object to be processed; a lid 120 that covers the drum 102 in an openable and closable manner; a motor 105 that rotates the drum 102; a liquid spraying device 140 that supplies mist into the drum 102; and a control unit 131 that can execute a mist supply program for operating the liquid spraying device 140. In the mist supply program, the control unit 131 causes the motor 105 to operate to rotate the drum 102 for a predetermined time after stopping the liquid spraying device 140.

[0156] Thereby, the mist can be attached to the inner wall of the drum 102 by the centrifugal force generated by the rotation of the drum 102. Further, when an object to be processed is housed in the drum 102, after operating the liquid spraying device 140 to supply mist, the drum 102 is rotated to tumble the object to be processed, whereby the mist remaining in the drum 102 can be attached to the object to be processed.

[0157] Therefore, it is possible to suppress the mist from remaining in the drum 102 without being attached to the object to be processed, the drum 102, or the like, and thus it is possible to suppress the user from inhaling the mist when the lid 120 is opened.

[0158] As in the present embodiment, the dryer 100 may include a lid locking portion that holds the lid 120 in a closed state. In the mist supply program, the control unit 131 locks the lid 120 in the closed state by the lid locking portion, and releases the locking by the lid locking portion when a predetermined time has elapsed after stopping the liquid spraying device 140.

[0159] Thereby, it is possible to suppress the lid 120 from being opened in a state where the mist remains in the drum 102 after operating the liquid spraying device 140 to supply mist.

[0160] Therefore, it is possible to suppress the user from opening the lid 120 and inhaling the mist remaining in the drum 102.

[0161] As in the present embodiment, the dryer 100 may include a reception unit 132 that receives an instruction from the user. When the reception unit 132 receives an instruction to stop the operation during the operation of the mist supply program, the control unit 131 stops the operation of the mist supply program after stopping the liquid spraying device 140 and operating the motor 105 to rotate the drum 102 for a predetermined time.

[0162] Thereby, when an instruction to stop the operation is received during the operation of the mist supply program, the drum 102 is rotated to tumble the object to be processed, whereby the mist supplied into the drum 102 can be attached to the object to be processed.

[0163] Therefore, it is possible to reduce the remaining mist in the drum 102 when the operation of the mist supply program stops and the lid 120 may be opened by the user, and thus it is possible to prevent the user from inhaling the mist when opening the lid 120.

[0164] As in the present embodiment, the dryer 100 may include a notification unit 133. When the reception unit 132 receives an instruction to stop the operation during the operation of the mist supply program, during the period when the liquid spraying device 140 is stopped and the motor 105 is operated to rotate the drum 102 for a predetermined time, the notification unit 133 notifies the first information (meaning that the operation continues).

[0165] Thereby, it is possible to make the user recognize that the operation continues after receiving the instruction to stop the operation.

[0166] Therefore, it is possible to make the user recognize that the drum 102 is rotating after the user instructs to stop the operation, which means it is not a malfunction.

[0167] As in the present embodiment, the dryer may include an air supply path 110 and a fan 104. The air supply path 110 is provided outside the drum 102 for the air flowing into the drum 102 to pass through. The fan 104 is provided in the air supply path 110 to blow air into the drum 102, and the liquid spraying device 140 is provided outside the air supply path 110.

[0168] Thereby, it is possible to prevent the mist supplied by the liquid spraying device 140 from flowing out of the drum 102.

[0169] As in the present embodiment, the control unit 131 may operate the fan 104 after stopping the liquid spraying device 140 and operating the motor 105 to rotate the drum 102 during the mist supply program.

[0170] Thereby, before operating the fan 104, the drum 102 is rotated to tumble the object to be processed, so that the remaining mist in the drum 102 adheres to the object to be processed, and thus it is possible to prevent the mist from flowing out of the drum 102.

[0171] Therefore, it is possible to prevent devices outside the drum 102, such as the heater 111, from being deteriorated due to the adhesion of the mist.

[0172] As in the present embodiment, the control unit 131 may set the rotation speed of the fan 104 to a second rotation speed N2 that is equal to or lower than the first rotation speed N1, or stop the fan 104 during the operation of the liquid spraying device 140.

[0173] Thereby, it is possible to prevent the mist supplied by the liquid spraying device 140 from flowing out of the drum 102 due to the wind generated by the fan 104.

[0174] Therefore, it is possible to suppress the deterioration of devices outside the drum 102 such as the heater 111 due to the adhesion of fog.

[0175] As in the present embodiment, it may also be that the control unit 131 does not operate the fan 104 during the operation of the liquid spraying device 140.

[0176] Thereby, it is possible to suppress the fog supplied by the liquid spraying device 140 from flowing out of the drum 102 due to the wind generated by the fan 104.

[0177] Therefore, it is possible to suppress the deterioration of devices outside the drum 102 due to the adhesion of fog.

[0178] As in the present embodiment, the dryer 100 may also include a liquid tank 141 for storing a liquid. The liquid spraying device 140 may also spray the liquid stored in the liquid tank 141.

[0179] Thereby, the liquid sprayed by the liquid spraying device 140 can be stored in the liquid tank 141.

[0180] [1-3-5. Effect 5]

[0181] As described above, in the present embodiment, the dryer 100 includes: a drum 102 that houses an object to be processed; a lid 120 that covers the drum 102 in an openable and closable manner; a liquid spraying device 140 that supplies fog into the drum 102; a control unit 131 that can execute a fog supply program for operating the liquid spraying device 140; and a lid locking unit that holds the lid 120 in a closed state. In the fog supply program, during the operation of the liquid spraying device 140, the control unit 131 locks the lid 120 in the closed state through the lid locking unit.

[0182] Thereby, since there is fog in the drum 102 during the operation of the liquid spraying device 140, it is possible to suppress the lid 120 from being opened by the user by locking the lid 120 in the closed state.

[0183] Therefore, it is possible to suppress the user from opening the lid 120 and inhaling the fog in the drum 102.

[0184] As in the present embodiment, it may also be that the control unit 131 unlocks through the lid locking unit after a predetermined time has elapsed since the liquid spraying device 140 stops in the fog supply program.

[0185] Thereby, after the operation of the liquid spraying device 140 to supply fog, until the fog floating in the drum 102 falls to the lower part of the drum 102 or onto the object to be processed, it is possible to suppress the lid 120 from being opened by the user.

[0186] Therefore, it is possible to prevent the user from opening the lid 120 and inhaling the mist remaining in the drum 102.

[0187] As in the present embodiment, it may be configured such that there is a reception unit 132 that receives an instruction from the user. When the reception unit 132 receives an instruction to stop the operation during the operation of the mist supply program, the control unit 131 stops the liquid spraying device 140, and after a predetermined time has elapsed since the liquid spraying device 140 was stopped, the lid locking unit releases the locking.

[0188] Thereby, even when an instruction to stop the operation is received from the user, it is possible to prevent the lid 120 from being opened with mist remaining in the drum 102.

[0189] Therefore, it is possible to prevent the user from opening the lid 120 and inhaling the mist remaining in the drum 102.

[0190] As in the present embodiment, it may be configured such that there is a notification unit 133. When the reception unit 132 receives an instruction to stop the operation during the operation of the mist supply program, during the period in which the lid 120 is locked by the lid locking unit, the notification unit 133 notifies first information related to the lid 120 (meaning that the lid 120 cannot be opened).

[0191] Thereby, it is possible to make the user recognize the meaning that the lid 120 cannot be opened after receiving an instruction to stop the operation.

[0192] Therefore, it is possible to make the user recognize that the situation where the lid 120 cannot be opened after the user instructs to stop the operation is not a malfunction.

[0193] (Embodiment 2)

[0194] Next, Figure 15 Embodiment 2 will be described. In Embodiment 2, a dryer 200 is described as a clothing treatment device. The dryer 200 differs from the dryer 100 in that the air flow is different. Therefore, the description of the same points as in Embodiment 1 regarding the structure of the control device 130 and the liquid spraying device 140 is omitted.

[0195] [2-1. Structure]

[0196] The dryer 200 has a drum 202 provided in a housing 101. The drum 202 is provided in the housing 101 so as to be rotatable about a rotation axis X extending in a substantially horizontal direction.

[0197] Protrusions 203 are provided on the inner wall of the drum 202. Air outlets 207 are formed in the protrusions 203 as a plurality of ventilation holes that communicate the inside and outside of the protrusions 203.

[0198] A fan 204, which is a suction component for sucking air from inside the drum 202, is provided at the inner rear part of the housing 101. When the fan 204 rotates, air inside the drum 202 is sucked from a suction port 206 provided at the rear of the drum 202 toward the fan 204. The air sucked by the fan 204 flows into the drum 202 through an air outlet 207 of a protrusion 203 via the protrusion 203. In the present embodiment, an air passage from the suction port 206 until the air is sucked by the fan 204 and flows into the drum 202 through the air outlet 207 is defined as a blowing path 210. In addition, since the fan 204 blows the air sucked from inside the drum 202 into the drum 202 via the protrusion 203, the fan 204 can also be defined as a blowing component.

[0199] (Embodiment 3)

[0200] Next, Figure 16 Embodiment 3 will be described. In Embodiment 3, a drum-type washing and drying machine 300 will be described as a laundry processing apparatus. The drum-type washing and drying machine 300 differs from the drying machines 100 and 200 in terms of its internal structure. Therefore, descriptions of the structure of the liquid spraying device 140 and the like that are the same as those in Embodiments 1 and 2 are omitted.

[0201] The drum-type washing and drying machine 300 includes a water tank 301 capable of storing water provided inside the housing 101 and a drum 302 rotatably provided inside the water tank 301. A large number of water passing holes 302a that communicate with the water tank 301 in a water-passing manner are provided on the peripheral wall of the drum 302. In addition, the rotation axis Y of the water tank 301 and the drum 302 can be set to incline from horizontal to the front upper side or can be set to extend horizontally.

[0202] A water supply valve 361 for taking in water from the outside, a water supply path 362 for allowing the water taken in by the water supply valve 361 to flow into the water tank 301, a drain valve 363 for discharging the water in the water tank 301, and a drain path 364 for discharging the water to the outside when the drain valve 363 is opened are provided inside the housing 101. Thus, the drum-type washing and drying machine 300 can perform a washing operation including a washing process, a rinsing process, and a dehydration process.

[0203] A tank lid 301c that covers a part of the opening of the drum 302 is provided on the front surface side of the water tank 301. The tank lid 301c can be provided on the water tank 301 or can be provided on the housing 101. In the present embodiment, the nozzle unit 150 is provided on the tank lid 301c.

[0204] The drum - type washing and drying machine 300 has a fan 304 that pressurizes and conveys air, a suction port 306 provided above the water tank 301, and an air outlet 307 provided on the back surface of the water tank 301. When the fan 304 rotates, the air in the water tank 301 is sucked in from the suction port 306, and the air sucked in by the fan 304 flows into the water tank 301 from the air outlet 307. In this embodiment, the air passage from the suction port 306 until the air is sucked in by the fan 304 and flows into the water tank 301 from the air outlet 307 is defined as the air supply path 310. In addition, since the fan 304 blows the air sucked in from the water tank 301 into the water tank 301 via the air supply path 310, the fan 304 can also be defined as an air supply component. The fan 304 is provided in the air supply path 310. The air flowing into the water tank 301 from the air outlet 307 flows into the drum 302 through the ventilation holes provided on the back surface of the drum 302, and flows out toward the water tank 301 through the water - passing holes 302a provided on the peripheral wall of the drum 302.

[0205] The drum - type washing and drying machine 300 includes a heat pump unit 311 as a heating component in the air supply path 310. The heat pump unit 311 is a device for dehumidifying and heating the air in the air supply path 310.

[0206] The drum - type washing and drying machine 300 includes a control device 330. The control device 330 controls the operations of the fan 304, the heat pump unit 311, the water supply valve 361, the drain valve 363, etc., in addition to rotating the drum 302 by the motor 105.

[0207] (Other embodiments)

[0208] As illustrated above, as examples of the technologies disclosed in this application, Embodiments 1 - 3 have been described. However, the technologies in this disclosure are not limited thereto, and can also be applied to embodiments obtained by making changes, replacements, additions, omissions, etc. In addition, the constituent elements described in the above - mentioned Embodiments 1 - 3 can be combined to form new embodiments.

[0209] Therefore, other embodiments are illustrated below.

[0210] In the above - mentioned embodiments, as an example of the motor, the motor 105 that drives the drums 102, 202, 302 to rotate has been described. The motor is not limited to the motor 105 that drives the drums 102, 202, 302 to rotate, and may have a structure that drives both the receiving tank (drums 102, 202, 302) and the fans (104, 204, 304) to rotate.

[0211] In the above-described embodiment, as an example of the mist supply component, the liquid spraying device 140 having the air pump 143 and the spray nozzle 154 as a two-fluid nozzle was described. The mist supply component only needs to be a component that sprays mist, and thus is not limited to the liquid spraying device 140. The mist supply component may also be a liquid feed pump, or an ultrasonic oscillator may be used.

[0212] In the above-described embodiment, as an example of the nozzle mounting portion, the nozzle mounting portion 153 connected between the air supply path 144 and the spray nozzle 154 was described. The nozzle mounting portion only needs to be connected between the path through which the fluid passes and the spray nozzle (spray nozzle 154), and thus may also be provided to be connected between the liquid supply path (liquid supply path 142) and the spray nozzle (spray nozzle 154).

[0213] In the above-described embodiment, as an example of the bending structure for bending the path of the nozzle mounting portion 153, the bending structure 153a that bends the path inside the nozzle mounting portion 153 at a right angle was described. The bending structure only needs to bend the path through which the fluid flowing into the spray nozzle passes, and thus is not limited to the bending structure 153a provided in the nozzle mounting portion 153. When the liquid supply path or the air supply path is directly mounted on the spray nozzle, the bending structure may also be a structure that directly bends the liquid supply path or the air supply path. In addition, the bending structure only needs to bend the path inside the nozzle mounting portion by 1 degree to 90 degrees. Further, in the case of using a two-fluid nozzle in which 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 perpendicularly as the spray nozzle, if the bending structure is a structure that bends the path through which the fluid flowing into the spray nozzle passes by 90 degrees, space savings for arranging the nozzle portion, the air supply path, and the liquid supply path can be achieved.

[0214] In the above-described embodiment, as an example of the first program for operating the mist supply device, a mist supply program for operating the liquid spraying device 140 in a state where the object to be received is received has been described. The first program only needs to be a program for operating the mist supply device, and thus is not limited to the mist supply program. The first program may also consist only of a spraying process. In this case, the rotational speed of the fan in the spraying process may be set to a rotational speed lower than the rotational speed of the fan in the air supply process, or may be set to a rotational speed lower than the rotational speed of the fan in other programs for drying the object to be processed. In addition, the first program may also be a tank care program in which the mist supply device is operated in a state where no clothes are received in the receiving tank (drums 102, 202, 302) to attach mist to the tank (drums 102, 202, 302, water tank 301). In addition, the first program may be such that, when the clothes processing device is capable of washing the object to be received, a spraying process is performed after at least one of the cleaning process, the rinsing process, and the dehydration process. In addition, the first program may be set to be capable of performing an air supply process for driving the air supply member before and / or after the spraying process, or may be set to perform a process for operating the heating member during the execution of the air supply process.

[0215] In the above-described embodiment, as an example of the liquid tank for receiving the liquid, a liquid tank 141 that can be taken out from inside the housing 101 for refilling has been described. The liquid tank only needs to receive the liquid sprayed by the mist supply member, and thus is not limited to the liquid tank 141. The liquid tank may also be a box that cannot refill the liquid received inside.

[0216] In the above-described embodiment, as an example of the spray nozzle, a spray nozzle 154 provided at a position above the rotation axis X of the liquid tank 141 and the drum 102 has been described. The spray nozzle only needs to be a member for spraying the liquid received in the liquid tank, and thus the position where the spray nozzle is disposed is not limited. When the spray nozzle is provided at a position below the liquid tank, the liquid supplied from the liquid tank to the spray nozzle is not easily affected by the lift, and thus the output of the air pump or the liquid feed pump can be reduced. In addition, when the spray nozzle is located at a position below the center of the receiving tank, the liquid supplied from the liquid tank to the spray nozzle is also not easily affected by the lift, and thus the output of the air pump or the liquid feed pump can be reduced.

[0217] In the above-described embodiment, as an example of the mist supply member, a liquid spraying device 140 provided outside the air supply path 110 (air supply path 210, air supply path 310) has been described. The mist supply member only needs to supply mist into the receiving tank, and thus is not limited to being provided in the liquid spraying device 140. The mist supply member may also be provided inside the air supply path, or a air supply member may be provided near the spray nozzle of the liquid spraying device in order to deliver the mist into the receiving tank.

[0218] In the above-described embodiments, as an example of the first member for fixing the nozzle unit, the groove cover 101c (Embodiment 1) and the groove cover 301c (Embodiment 3) have been described. The nozzle unit only needs to be installed so as to be able to supply mist into the storage grooves (drums 102, 202, 302), and thus is not limited to the groove cover 101c and the groove cover 301c. The first member may also be a lid body (lid body 120), or may be a part of the housing (housing 101), or may be a part of the water tank (water tank 301) or the storage groove (drums 102, 202, 302).

[0219] In Embodiment 1, as an example of the heating component, the heater 111 that heats the air in the air supply path 110 has been described. The heating component only needs to be a component that heats the air in the air supply path, and thus is not limited to the heater 111. The heating component may also be a heat pump unit that dehumidifies and heats the air in the air supply path as described in Embodiment 3.
