The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0062] like Figures 1 to 9As shown, according to an embodiment of the present invention, a clothes processing device 100 is proposed, which includes a housing 10, a door assembly 20 and a filter 30. The housing 10 is provided with a take-in and take-out port 1112, a drying air duct and a clothes processing chamber 121. The clothes processing chamber 121 is connected to the outside through the take-in and take-out port 1112, and the drying air duct is connected to the clothes processing chamber 121. The door assembly 20 includes a door switch 22 and a door body 21. The door body 21 is pivotally connected to the housing 10. When the door body 21 rotates relative to the housing 10, the take-in and take-out port 1112 can be opened or closed. The door switch 22 is fixedly mounted on the housing 10. The filter element 30 is installed on the housing 10 in a detachable manner, and the filter element 30 has an uninstalled state and an installed state relative to the housing 10. When the filter element 30 is in the installed state, the door body 21 closes the access port 1112, the door body 21 cooperates with the filter element 30, the filter element 30 cooperates with the door switch 22 and triggers the door switch 22, the door switch 22 is triggered to connect the circuit in the clothing processing device 100, and when the filter element 30 is not installed, the door body 21 closes the access port 1112, and in the absence of the filter element 30, the door switch 22 is spaced apart from the door body 21, and the door switch 22 cannot be triggered to disconnect the circuit in the clothing processing device 100.

[0063] According to the clothing processing device 100 of the present invention, when the filter element 30 is in an uninstalled state, the door body 21 cannot trigger the door switch 22, at which time the circuit of the clothing processing device 100 is disconnected and the clothing processing device 100 cannot be started; when the filter element 30 is in an installed state, the door body 21 can trigger the door switch 22 through the filter element 30, at which time the circuit of the clothing processing device 100 is connected, and the clothing processing device 100 can be started and operated.

[0064] By forming a combined structure in which the filter element 30 and the door switch 22 are dependent on each other, the user can be reminded that the filter element 30 is not installed by failing to start and operate the clothing processing device 100 when the filter element 30 is not installed, thereby reducing the possibility of malfunction of the clothing processing device 100 due to the filter element 30 not being installed.

[0065] It should be understood that the clothing processing chamber 121 is used to process clothing. The loading and unloading port 1112 is used for users to put clothing into the clothing processing chamber 121 or take clothing out of the clothing processing chamber 121. The drying air duct is used to provide hot air into the clothing processing chamber 121, and use the hot air to dry the clothing in the clothing processing chamber 121, and the hot and humid air after heat exchange is discharged through the drying air duct.

[0066] In an embodiment of the present invention, when the door body 21 closes the access opening 1112, the transmission of the filter element 30 is required to trigger the door switch 22. At this time, if the filter element 30 is not installed, the door body 21 cannot trigger the door switch 22, so that the circuit of the clothing processing device 100 cannot be turned on, that is, the user cannot use the clothing processing device 100. Based on this, the purpose of reminding the user to install the filter element 30 can be achieved.

[0067] It should be noted that, in the embodiment of the present invention, the door switch 22 is connected to the control circuit of the clothing processing device 100. When the door switch 22 is not triggered, the control circuit of the clothing processing device 100 is in an open circuit state. When the door switch 22 is triggered, the control circuit of the clothing processing device 100 is in an open circuit state. When the control circuit is in an open circuit state, the clothing processing device 100 cannot be started and operated. When the control circuit is in an open circuit state, the clothing processing device 100 can be started and operated.

[0068] In addition, after the filter 30 is installed in place on the box 10, the filter 30 cuts off the drying channel. At this time, the airflow entering the drying duct needs to pass through the filter 30. When the airflow passes through the filter 30, foreign matter (lint or hair, etc.) carried in the airflow is intercepted by the filter 30 to reduce the situation where foreign matter causes malfunction of the foreign matter handling equipment.

[0069] In some embodiments of the present invention, Figures 3 to 7 As shown, the filter element 30 includes a mounting frame 31, a filter body 34 and a movable seat 32. The mounting frame 31 is mounted on the housing 10, and the two are matched in a detachable manner. The filter body 34 is fixedly mounted on the mounting frame 31. When the mounting frame 31 is fixedly mounted on the housing 10, at least part of the filter body 34 is arranged in the drying air duct, and the airflow in the drying air duct is filtered by the filter body 34.

[0070] The movable seat 32 is mounted on the mounting frame 31, and the movable seat 32 can move relative to the mounting frame 31. The movable seat 32 has a first state and a second state on the mounting frame 31, and the first state and the second state can be switched to each other. When the door body 21 opens the access port 1112, the movable seat 32 is in the first state, and the door switch 22 is separated from the movable seat 32. When the door body 21 closes the access port 1112, the movable seat 32 is in the second state, and the door switch 22 and the door body 21 are respectively in contact with the movable seat 32.

[0071] Specifically, the movable seat 32 is utilized to switch between the first state and the second state, so that when the door body 21 opens the access port 1112, the door switch 22 is not triggered, so that the control circuit of the clothing processing device 100 is disconnected; and when the door body 21 closes the access port 1112, the door switch 22 is triggered, so that the control circuit of the clothing processing device 100 is connected, thereby effectively realizing that the door body 21 triggers the door switch 22 through the filter element 30, so that when the filter element 30 is not installed, the user can be reminded by the failure of the clothing processing device 100 to start, thereby realizing the effective installation of the filter element 30 and reducing the possibility of malfunction of the clothing processing device 100 due to the failure to install the filter element 30.

[0072] It should be understood that the mounting frame 31 and the door switch 22 are respectively mounted and fixed on the box body 10, the movable seat 32 can be movably mounted on the mounting frame 31, and the door body 21 can drive the movable seat 32 to move relative to the mounting frame 31, so that when the door body 21 closes the access port 1112, the door body 21 can trigger the door switch 22 through the movable seat 32.

[0073] In addition, when the door body 21 opens the access opening 1112, the movable seat 32 is in a first state. In the first state, the door body 21 does not apply a force to the movable seat 32. At this time, the movable seat 32 also does not apply a force to the door switch 22. The door switch 22 that is not applied with a force is in a non-triggered state.

[0074] It should be pointed out that if Figure 4 , Figure 5 as well as Figure 7 As shown, the detachable manner between the mounting frame 31 and the front side plate 111 includes but is not limited to snap connection or screw connection. The connection and fixing manner between the filter body 34 and the mounting frame 31 includes but is not limited to bonding or snap connection. The filter body 34 is a porous structure and is arranged on the mounting frame 31. The porous structure allows airflow to pass through, and foreign matter such as hair scraps cannot pass through the porous structure, thereby filtering the airflow. In addition, the filter part can be a sponge, filter paper, etc.

[0075] In some embodiments of the present invention, a receiving groove 311 for accommodating the movable seat 32 is provided on the mounting frame 31, the movable seat 32 is movably arranged in the receiving groove 311, and the movable seat 32 can move relative to the receiving groove 311 in the direction from the door body 21 to the door switch 22.

[0076] Specifically, a receiving groove 311 is provided, and the receiving groove 311 is used to receive the movable seat 32, so that the movable seat 32 can be effectively installed, and at the same time, the side wall of the receiving groove 311 can be used to limit the movable seat 32, so that the movable seat 32 moves relative to the receiving groove 311 in the direction from the door body 21 to the door switch 22, and then the movement of the movable seat 32 can be used to switch between the first state and the second state.

[0077] It should be pointed out that a protruding structure 211 is provided on the door body 21. When the door body 21 closes the access opening 1112, the protruding structure 211 passes through the notch of the receiving groove 311 and abuts against the movable seat 32, thereby driving the movable seat 32, so that the movable seat 32 moves relative to the mounting frame 31 and abuts against the door switch 22, thereby triggering the door switch 22.

[0078] In some embodiments of the present invention, Figure 4 , Figure 5 as well as Figure 7 As shown, a first limiting structure 312 is provided on the receiving groove 311, and a second limiting structure 321 is provided on the movable seat 32. When the door body 21 opens the access opening 1112, the movable seat 32 is in the first state, at which time the first limiting structure 312 and the second limiting structure 321 cooperate, so that at least part of the body of the movable seat 32 is accommodated in the receiving groove 311.

[0079] Specifically, by providing the first limiting structure 312 and the second limiting structure 321 , and utilizing the cooperation between the first limiting structure 312 and the second limiting structure 321 to limit the moving stroke of the movable seat 32 , the movable seat 32 is effectively prevented from escaping from the receiving groove 311 .

[0080] It should be understood that when the movable seat 32 is in the first state, the first limiting structure 312 cooperates with the second limiting structure 321. At this time, the movable seat 32 can be partially disposed in the receiving groove 311, or the movable seat 32 can be entirely disposed in the receiving groove 311.

[0081] In some embodiments of the present invention, the first limiting structure 312 may be a first protrusion formed on the side wall of the receiving groove 311, and the second limiting structure 321 may be a second protrusion formed on the outer peripheral surface of the movable seat 32. The movable seat 32 is limited by the abutment between the first protrusion and the second protrusion.

[0082] In some embodiments of the present invention, Figure 4 , Figure 5 as well as Figure 7As shown, the first limiting structure 312 is a convex rib formed at the notch of the receiving groove 311 , and the second limiting structure 321 is a convex ring formed on the outer peripheral surface of the movable seat 32 .

[0083] Specifically, the convex rib is arranged around the notch of the receiving groove 311 and extends toward the inner side of the receiving groove 311. At the same time, the convex rib is arranged around the notch, so that the notch of the receiving groove 311 is reduced. The convex ring is formed on the outer peripheral surface of the movable seat 32 and is arranged around the movable seat 32. The size of the movable seat 32 at the position of the convex ring is increased. Along the moving direction perpendicular to the movable seat 32, the opening size of the convex rib position is smaller than the size of the convex ring position, so that the convex ring cannot pass through the convex rib position, thereby achieving the limitation of the movable seat 32.

[0084] The convex rib structure is formed at the notch of the receiving groove 311 and is an integral structure with the mounting frame 31. The convex ring is formed on the movable seat 32 and is an integral structure with the movable seat 32. The limiting structure formed by the convex ring and the convex rib has a better limiting effect and a lower manufacturing cost.

[0085] In some embodiments of the present invention, Figure 4 , Figure 5 as well as Figure 7 As shown, a through hole 313 is opened on the side of the receiving groove 311 , and the through hole 313 is arranged facing the door body 21 . The door switch 22 includes a contact 221 , wherein the contact 221 passes through the through hole 313 and enters the interior of the receiving groove 311 .

[0086] Specifically, a receiving groove 311 is provided on the mounting frame 31 of the filter element 30, and the movable seat 32 is movably arranged in the receiving groove 311. A through hole 313 is provided on the bottom surface of the receiving groove 311 (the side of the receiving groove 311 facing the door body 21), and the outlet passes through the through hole 313 and enters the interior of the receiving groove 311. When the door body 21 opens the access opening 1112, the movable seat 32 is in the first state, at which time the movable seat 32 and the contact 221 are spaced apart, and the door switch 22 is not triggered; when the door body 21 closes the access opening 1112, the protruding structure 211 of the door body 21 abuts against the movable seat 32, so that the movable seat 32 moves relative to the mounting frame 31, thereby switching from the first state to the second state. When the movable seat 32 moves to the second state, the movable seat 32 abuts against the contact 221, so that the door switch 22 is triggered.

[0087] The combined structure formed by the filter element 30 and the door switch 22 has a simple structure and is easy to process and manufacture, thereby effectively reducing the manufacturing cost. In addition, the combined structure formed by the filter element 30 and the door switch 22 has a good transmission effect, and can effectively realize the transmission of the driving force when the door body 21 is closed, so as to realize the purpose of connecting the control circuit of the clothing processing device 100 when the filter element 30 is installed, and disconnecting the control circuit of the clothing processing device 100 when the filter element 30 is not installed to remind the user to install the filter element 30.

[0088] In some embodiments of the present invention, Figure 4 , Figure 5 as well as Figure 7 As shown, the filter element 30 further includes an elastic member 33 respectively matched with the mounting frame 31 and the movable seat 32. After being installed, the elastic member 33 has a rebound force that drives the movable seat 32 to have a tendency to switch to the first state.

[0089] Specifically, the elastic member 33 cooperates with the mounting seat 41 and the movable seat 32 respectively. When the filter element 30 is installed on the box body 10, when the door body 21 opens the access port 1112, the rebound force of the elastic member 33 drives the movable seat 32 to remain in the first state. At this time, the second limiting structure 321 of the movable seat 32 abuts against the first limiting structure 312 at the notch position of the receiving groove 311 of the mounting frame 31. When the door body 21 closes the access port 1112, the protruding structure 211 on the door body 21 abuts against the movable seat 32. The protruding structure 211 drives the movable seat 32 to overcome the rebound force of the elastic member 33 (the elastic member 33 is further compressed) and switch to the second state until the movable seat 32 abuts against the contact 221 of the door switch 22, thereby triggering the door switch 22 and further realizing the connection of the control circuit of the clothing processing device 100. When the door body 21 opens the access opening 1112 again, the protruding structure 211 of the door body 21 contacts the movable seat 32, and the rebound force of the elastic member 33 drives the movable seat 32 to switch to the first state, so that the movable seat 32 is separated from the contact 221 of the door switch 22, thereby realizing the disconnection of the control circuit of the clothing processing device 100.

[0090] The elastic member 33 is provided so that the movable seat 32 has a tendency to switch to the first state by utilizing the elastic member 33 , thereby realizing that the movable seat 32 can be automatically separated from the door switch 22 when the door body 21 is in the open state.

[0094] In some embodiments of the present invention, when the user faces the laundry processing device 100, the side of the laundry processing device 100 facing the user is the front side, the side of the laundry processing device 100 facing away from the user is the back side, the side of the laundry processing device 100 located on the left hand side of the user is the left side, the side of the laundry processing device 100 located on the right hand side of the user is the right side, the side of the laundry processing device 100 facing the ground is the bottom side, and the side of the laundry processing device 100 facing away from the bottom surface is the top side. Among them, the plate of the box body 11 located on the front side of the laundry processing device 100 is the front side plate 111.

[0095] The access opening 1112 is provided on the front side plate 111, so that the user can easily access the clothes. At the same time, the clothes treatment drum 12 is provided and is arranged to be rotatable relative to the box body 11, so that the clothes can be turned over by the rotation of the clothes treatment drum 12, thereby improving the efficiency of the clothes drying process.

[0096] It should be pointed out that the housing 10 further includes a driving member, which is in transmission connection with the laundry processing drum 12 , and the driving member is used to drive the laundry processing drum 12 to rotate, so as to realize turning over of the laundry.

[0097] In some embodiments of the present invention, Figure 4 , Figure 5 as well as Figure 7 As shown, a concave structure 1113 is provided on the front side plate 111, and the portion of the mounting frame 31 having the receiving groove 311 is embedded in the concave structure 1113. By providing the concave structure 1113, the portion of the mounting frame 31 having the receiving groove 311 can be embedded, thereby reducing the number of protruding structures, thereby reducing the overall volume of the clothing processing device 100.

[0098] In some embodiments of the present invention, the laundry processing device 100 has a drying function, that is, it can realize a drying operation on the laundry. The laundry processing device 100 further includes a drying assembly 40, and a drying channel is formed in the drying assembly 40.

[0099] Specifically, Figure 3 As shown, the drying assembly 40 includes a mounting seat 41, a first air duct 42, a second air duct 44 and a fan 43. The first air duct 42 has two opposite ends, and the second air duct 44 also has two opposite ends. One end of the first air duct 42 is connected to the mounting seat 41 and communicates with the clothing processing chamber 121 through the mounting seat 41, the other end of the first air duct 42 is communicated with the air inlet of the fan 43, and the first air outlet of the fan 43 is connected to one end of the second air duct 44. Part of the body of the filter element 30 is arranged inside the first air duct 42, and the flow cross section of the first air duct 42 is cut off, so that the airflow needs to pass through the filter element 30 before it can flow along the first air duct 42.

[0100] Driven by the fan 43, the air flow in the clothing processing chamber 121 flows through the first connecting port, the mounting seat 41, the first air duct 42, the fan 43 and the second air duct 44. When the air flow flows along the first air duct 42, the air flow needs to pass through the filter element 30. When the air flow passes through the filter element 30, the filter element 30 filters the hair and other materials carried in the air flow. The filtered air flow enters the second air duct 44 through the fan 43.

[0101] The filter element 30 is disposed in the first air duct 42 so that the airflow is effectively filtered before entering the fan 43 , thereby reducing the possibility of foreign matter such as hair debris entering the fan 43 and causing the fan 43 to malfunction.

[0102] It should be understood that the fan 43 can drive the airflow to flow effectively, so that the flow rate of the airflow is increased, thereby improving the drying effect of the clothes.

[0103] In some embodiments of the present invention, Figure 3 As shown, the drying assembly 40 also includes a heating element 45 and a third air duct 46 .

[0104] Specifically, the third air duct 46 has two opposite ends, and the heating channel of the heating element 45 has a second air inlet and a second air outlet. The clothing processing chamber 121 is connected to one end of the third air duct 46, and the other end of the third air duct 46 is connected to the second air outlet of the heating channel.

[0105] When the drying component 40 is running, the fan 43 is running. Under the action of the fan 43, the air flow in the clothing processing chamber 121 enters the first air duct 42 through the first connecting port. The air flow enters the first air duct 42, causing a negative pressure in the clothing processing chamber 121. The air flow enters the heating channel through the second air inlet and is heated. The heated air flow enters the third air duct 46 through the second air outlet and flows along the third air duct 46. The air flow entering the third air duct 46 enters the clothing processing chamber 121 and heats and dries the clothes in the clothing processing chamber 121. The dried air flow enters the first air duct 42 and flows along the second air duct 44. The filter element 30 arranged in the first air duct 42 filters the passing air flow so that hair and other clothes in the air flow are filtered out. The filtered air flow enters the fan 43 through the first air inlet of the fan 43, and enters the second air duct 44 through the first air outlet of the fan 43.

[0106] By utilizing the drying component 40, hot air flow is allowed to enter the clothing processing chamber 121 to dry the clothing, thereby improving the drying efficiency of the clothing, and further improving the clothing processing rate, reducing the user's waiting time, and effectively improving the user experience.

[0107] It should be pointed out that the heating element 45 includes a shell and a heating element (the heating element is a heating wire or other element), the second air inlet and the second air outlet are arranged at opposite ends of the shell, the interior of the shell constitutes a heating channel, the heating element can be arranged in the heating channel, and can also be arranged on the outside of the shell or in the inner wall of the shell. When the airflow passes through the heating channel, the heating element exchanges heat with the airflow entering the heating channel, so that the temperature of the airflow increases, and the heated airflow enters the third air duct 46 through the second air outlet, and enters the clothing processing chamber 121 through the third air duct 46.

[0108] In addition, the connection position between the third air duct 46 and the clothing processing chamber 121 can be set as needed. In the embodiment of the present invention, the third air duct 46 is connected to the bottom wall of the clothing processing chamber 121 (the wall of the clothing processing chamber 121 facing the door body 21), and the connection position is higher than the central axis of the access passage, the air outlet position of the clothing processing chamber 121 is the first connection port, and the air inlet position of the clothing processing chamber 121 is the connection position between the third air duct 46 and the clothing processing chamber 121. By setting the air inlet position and the air outlet position of the clothing processing chamber 121, the flow path of the airflow in the clothing processing chamber 121 can be extended, thereby increasing the contact time between the hot airflow and the clothing, and further improving the drying efficiency of the clothing.

[0109] In some embodiments of the present invention, the air outlet end of the second air duct 44 is connected to the second air inlet of the heating channel of the heating element 45. By connecting the second air duct 44 to the heating channel, a closed-loop gas flow is formed between the drying assembly 40 and the clothing processing chamber 121, thereby reducing the emission of gas to the outside, thereby reducing the adverse effects of the exhausted hot air on the surrounding environment.

[0110] It should be pointed out that the airflow entering the heating channel of the heating element 45 through the second air duct 44 has a certain temperature, which can improve the heating efficiency of the heating element 45 and effectively reduce the energy consumption of the heating element 45.

[0111] In some embodiments of the present invention, the air outlet of the second air duct 44 is connected to the outside, and the second air inlet of the heating channel of the heating element 45 is also connected to the outside. During the operation of the drying component 40, the outside airflow enters the heating channel and is heated, and the heated airflow enters the clothing processing chamber 121 through the third air duct 46. The airflow entering the clothing processing chamber 121 exchanges heat with the clothing, so that the clothing is dried. The airflow after the heat exchange enters the first air duct 42 through the first connecting port, and is filtered by the filter element 30 to remove foreign matter such as hair scraps, and then discharged to the outside through the fan 43 and the second air duct 44.

[0112] By connecting the second air duct 44 and the heating channel to the outside respectively, fresh air can be used to dry the clothes, reducing the generation of odor during the drying process of the clothes, so that the drying quality of the clothes is effectively improved.

[0113] In some embodiments of the present invention, the door body 21 forms a projection area on the front side plate 111 when the access opening 1112 is closed, wherein the installation opening is located inside the projection area. By arranging the installation opening inside the projection area, the door body 21 can shield the installation opening when closed, thereby reducing the exposure of the installation opening, and effectively improving the appearance coordination of the clothing processing device 100.

[0114] In addition, the installation port is set on the front side plate 111. When the user uses the clothing processing device 100, the user can directly obtain whether the filter element 30 is installed in the installation port, thereby achieving the purpose of reminding the user to install the filter element 30, and then enabling the user to effectively install the filter element 30, thereby reducing the adverse effects of clothing such as dander on the drying component 40.

[0116] A recessed structure 1111 is provided, and the recessed structure 1111 is utilized to accommodate the door body 21, so that the door body 21 is embedded in the front side plate 111, thereby reducing the protrusion of the door body 21 from the surface of the clothing processing device 100, and effectively reducing the volume of the clothing processing device 100.

[0117] It should be pointed out that the recessed structure 1111 is formed by the inner concave of the front side plate 111 , wherein the inner bottom surface of the recessed structure 1113 refers to the side surface of the recessed structure 1113 facing the door body 21 when the door body 21 closes the access opening 1112 .

[0118] In some embodiments of the present invention, the drying assembly 40 further includes a seal provided on the mounting port or the filter 30, and the seal is used to seal the joint position between the mounting port and the filter 30. By providing the seal, the airflow in the drying duct is reduced from escaping from the joint position between the mounting port and the filter 30, thereby reducing the adverse effects of the airflow escaping from the drying duct (such as scalding the user, etc.).

[0119] It should be pointed out that the sealing member is a rubber ring or a silicone ring or the like.

[0120] In the present invention, the above-mentioned clothing processing device is a dryer (in other embodiments of the present invention, the clothing processing device can also be a washing machine with a drying function, etc.), and the structure of other parts of the dryer please refer to the prior art, and this application will not repeat them here.

[0121] like Figure 8 and Fig. 9 As shown, the present invention further proposes a control method of a clothes processing device 100, and the control method of the clothes processing device 100 is implemented by the clothes processing device 100 as above, and the control method of the clothes processing device 100 includes:

[0123] Specifically, the clothes processing device 100 has a drying function. When the user uses the clothes processing device 100 to dry clothes, the user opens the door 21 of the clothes processing device 100, places the clothes to be dried into the clothes processing chamber, and turns on the power of the clothes processing device 100.

[0124] The controller of the clothing processing device 100 determines the state of the door switch 22 of the clothing processing device 100, wherein the state of the door switch 22 includes a closed state and an open state. The controller controls the clothing processing device 100 according to the different states of the door switch 22 to reduce the situation where the drying component 40 malfunctions due to the drying action being performed due to the filter 30 not being installed.

[0125] When the filter element 30 is installed on the clothing processing device 100, when the door body 21 is opened, the door switch 22 is in an off state, and when the door body 21 is closed, the door body 21 transmits the action to the door switch 22 through the filter element 30, so that the door switch 22 is closed. When the filter element 30 is not installed on the clothing processing device 100, when the door body 21 is opened, the door switch 22 is in an off state, and when the door body 21 is closed, the door body 21 cannot act on the door switch 22 to close the door switch 22. Therefore, when the door switch 22 is in an off state, it indicates that the filter element 30 is not installed on the clothing processing device 100.

[0126] The user sets the mode on the laundry processing device 100 so that the laundry processing device 100 enters the drying mode. Optionally, the user can set the drying mode before determining the door switch state of the laundry processing device, or can set the drying mode after determining the door switch state of the laundry processing device.

[0127] When the controller determines that the filter element 30 is not installed, it controls the clothing processing device 100 to issue an alarm prompt (for example, displaying "NF" or corresponding text information on the display window, etc.); in addition, a buzzer sound can also be emitted simultaneously to remind the user that the filter element 30 is not installed, thereby reducing the situation where the clothing processing device 100 is operated without the filter element 30 and causes damage to the drying component 40.

[0128] The control method of the laundry processing apparatus 100 further includes: determining that the laundry processing apparatus 100 is equipped with the filter element 30 according to the door switch 22 being in the closed state.

[0129] Specifically, when the door body 21 is closed, the door switch 22 is in a closed state, which indicates that the filter element 30 is installed between the door body 21 and the door switch 22, so that the door switch 22 is triggered, that is, it switches from the open state to the closed state, so that the state of the door switch 22 can be used to determine whether the filter element 30 is installed.

[0130] According to the installation of the filter element 30 in the laundry processing device, the laundry processing device 100 is controlled to perform a drying action;

[0131] Specifically, when the controller determines that the filter 30 is installed, it controls the clothing processing device 100 to perform a drying action, thereby satisfying the user's need to dry clothes and reducing the situation where the drying component 40 is damaged due to the clothing processing device 100 running without the filter 30.

[0132] According to the control method of the clothing processing device 100 of the present invention, when the filter element 30 is in an uninstalled state, the door body 21 cannot trigger the door switch 22. At this time, the circuit of the clothing processing device 100 is disconnected and the clothing processing device 100 cannot be started. When the filter element 30 is in an installed state, the door body 21 can trigger the door switch 22 through the filter element 30. At this time, the circuit of the clothing processing device 100 is connected, and the clothing processing device 100 can be started and operated. Therefore, by forming a combined structure in which the filter element 30 and the door switch 22 are dependent on each other, the user can be reminded that the filter element 30 is not installed by failing to start and operate the clothing processing device 100, thereby reducing the situation where the clothing processing device 100 malfunctions due to the failure to install the filter element 30.

[0133] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
