Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and in particular to a door assembly, clothing processing equipment, and control method. Background Technology

[0002] In related technologies, clothing processing equipment such as dryers typically have only one drying drum. Clothes of different materials or sizes are dried together in this drum; for example, underwear and large coats are dried together, or socks, shirts, and trousers are dried together. If you want to dry smaller items like underwear or socks separately, the smaller quantity of clothing compared to the typical 8kg to 10kg capacity of a dryer results in wasted energy. Users either have to air-dry the smaller items directly or accumulate them before drying them all at once, leading to considerable inconvenience. Summary of the Invention

[0003] In view of this, embodiments of this application aim to provide a door assembly capable of drying clothes, a clothes handling device, and a control method.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0005] One embodiment of this application discloses a door assembly, including:

[0006] The door has an air inlet for connecting with the outside world;

[0007] A housing, which covers the inside of the door to define the drying chamber, is used for heat exchange.

[0008] An air guide section extends from the air inlet toward the housing and is disposed in the drying chamber. The air guide section and the inner wall surface of the housing together define an air inlet channel to guide the air entering the drying chamber through the air inlet to the housing for heat exchange.

[0009] The wind turbine is disposed in the air inlet channel.

[0010] In one embodiment, the air guide divides the drying chamber into a clothes drying chamber and an air inlet channel.

[0011] In one embodiment, the drying chamber and the air inlet channel are isolated from each other, and the air guide is formed with an air outlet that connects the air inlet channel and the drying chamber.

[0012] In one embodiment, the door is provided with an air outlet communicating with the clothes drying cavity, and the air outlet and the air blower are respectively located on opposite sides of the clothes drying cavity.

[0013] In one embodiment, the air intake channel is arranged around the outer periphery of the clothes drying cavity.

[0014] In one embodiment, the air inlet channel includes an air guide section and an air blowing section. The air blowing section is located on the side of the clothes drying cavity away from the door. The air guide section connects the air inlet and the air blowing section and is located below the clothes drying cavity.

[0015] In one embodiment, the door has an opening for taking out and putting in clothes that communicates with the drying chamber.

[0016] In one embodiment, the air inlet is located below the take-up and put-out port.

[0017] In one embodiment, the door assembly includes a suspension mounted on the top side of the drying chamber for hanging clothing.

[0018] In one embodiment, the door assembly includes a temperature and humidity sensor and a heater, both of which are disposed in the drying chamber.

[0019] One embodiment of this application discloses a garment processing device, including:

[0020] The door assembly described in any of the above items;

[0021] The cylindrical assembly has a clothing inlet and a clothing cavity communicating with the clothing inlet, and the door is used to open or close the clothing inlet;

[0022] The circulating air duct is connected to the clothing cavity;

[0023] An impeller is installed in the circulating air duct.

[0024] Another aspect of this application discloses a control method for the clothing processing device described in the above embodiments, the control method comprising:

[0025] Start the drying mode;

[0026] Turn on the wind turbine and the impeller;

[0027] Based on the humidity in the drying chamber and the clothing chamber, determine whether there are clothes in the drying chamber and the clothing chamber.

[0028] The door assembly provided in this application, given the limited size of the garment processing equipment, utilizes the space between the door and the garment cavity to house the shell, making full use of the limited internal space and resulting in a more compact structure, without significantly increasing the size of the garment processing equipment. The relatively small volume of the drying cavity allows for the drying of small items such as underwear, socks, and / or infant clothing, eliminating the need to store large quantities of small items and addressing the inconvenience of drying small garments. Delicate materials like silk, which are easily damaged when dried directly in the drying cavity, can be prevented from snagging and fraying by placing them inside the drying cavity. The shell is concealed within the door, preventing it from being exposed and improving the overall aesthetics. The inclusion of a fan at the air inlet reduces drying time and user waiting time, resulting in high efficiency. During the simultaneous drying process in the clothing chamber and drying chamber, the heat from the airflow in the clothing chamber can be transferred to the airflow in the drying chamber using the outer shell. This fully utilizes the heat in the clothing chamber, saving energy and reducing costs. Even when no clothes are being dried in the clothing chamber, the airflow in the drying chamber can independently dry clothes, thus providing multiple drying options, high operational convenience, and good choice.

Detailed Implementation

[0035] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0036] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly including at least one feature.

[0037] This application provides a door assembly, please refer to... Figure 1 The door assembly 1 includes a door 11, a housing 12, an air guide 15, and a fan 13. The door has an air inlet 14a for communicating with the outside. The housing 12 covers the inside of the door 11 to define the drying chamber 14, and the housing 12 is used for heat exchange. The door 11 is used to open or close the clothes loading port of the drum assembly 2. The inside of the door 11 refers to the side facing the clothes chamber 21a of the drum assembly 2.

[0038] The position of the housing 12 covering the inside of the door 11 is not limited. For example, the housing 12 can be placed on the upper part of the inside of the door 11. This not only avoids other components located below the inside of the door 11, resulting in a compact structure and high integration, but also makes it easier for users to place clothes into the drying chamber 14, reducing the degree of bending over and saving time and effort. In some embodiments, the housing 12 can be a one-piece molded plate. The plate is formed by stamping or other methods to protrude from the direction away from the door 11 to form a groove. Then, the plate is fixed to the inner side of the door 11 by welding, snap-fitting, gluing, or screwing.

[0039] The air guide 15 extends from the air inlet 14a toward the housing 12 and is disposed in the drying chamber 14. The air guide 15 and the inner wall surface of the housing 12 together define an air inlet channel 142 to guide the air entering the drying chamber 14 from the air inlet 14a to the housing 12 for heat exchange.

[0040] The impeller 13 is disposed in the air inlet channel 142. In this way, the impeller 13 rotates to drive the outside airflow through the air inlet 14a and the air inlet channel 142 into the drying chamber 14. This accelerates the delivery of outside airflow into the drying chamber 14, thereby reducing the drying time of clothes and making it efficient and convenient.

[0041] The door assembly 1 provided in this embodiment has a limited size. Without increasing or significantly increasing the size of the clothing processing device 100, the housing 12 is installed in the space between the door 11 and the clothing cavity 21a of the clothing processing device 100, making full use of the limited internal space and resulting in a more compact structure. The drying cavity 14 has a relatively small volume, allowing small items such as underwear, socks, and / or infant clothing to be placed inside for drying. This eliminates the need to accumulate a large number of small items in the clothing cavity 21a for drying, addressing the inconvenience of drying small items. Clothing made of fragile materials such as silk is easily damaged by snagging and pulling when dried directly in the clothing cavity 21a. Placing such fragile materials in the drying cavity 14 reduces this damage. The housing 12 is installed inside the door 11, preventing it from being exposed and improving the overall aesthetics. By installing a fan 13 at the air inlet 14a, the drying time of clothes and the user's waiting time can be reduced, resulting in high efficiency. During the simultaneous drying process in the clothes chamber 21a and the drying chamber 14, the heat of the airflow in the clothes chamber 21a can be transferred to the airflow in the drying chamber 14 using the housing 12. This fully utilizes the heat in the clothes chamber 21a, saving energy and reducing costs. Even when no clothes are being dried in the clothes chamber 21a, the airflow in the drying chamber 14 can still dry clothes independently. This provides multiple drying options for clothes, offering high operational convenience and good choice.

[0042] In one embodiment, the door 11 has a loading / unloading port communicating with the drying chamber 14. For example, the location of the air inlet 14a on the door 11 is not limited. Taking a drum-type garment handling device 100 as an example, the loading / unloading port can be located in the middle area of ​​the door 11. Thus, even when the door 11 is in the closed loading / unloading port state, the user can still place clothes into or remove clothes from the drying chamber 14 through the loading / unloading port.

[0043] Understandably, the airflow from the air inlet 14a can be blown out from the outlet. Since the volume of the drying chamber 14 is relatively small, the moisture generated by the wet clothes in the drying chamber 14 will also be relatively small. The airflow in the drying chamber 14 is directly discharged to the outside, so it has little impact on the outside temperature and humidity.

[0044] In one embodiment, the loading and unloading port is provided on the housing 12. For example, the loading and unloading port can be provided on the side of the air guide 15 near the opening side of the door 11, so that small items of clothing can be put into the drying cavity 141 from the inside when the door 11 is open, which is convenient and quick.

[0045] In one embodiment, the air inlet 14a is located below the retrieval opening. This placement of the air inlet 14a below the retrieval opening makes it easier for the user to retrieve clothing. The lower position of the air inlet 14a also reduces the direct impact of external airflow on the upper body when the user is near the door 11, thus improving the user experience.

[0046] In one embodiment, please refer to Figure 1 and Figure 3 The air guide section 15 divides the drying chamber 14 into a clothes drying chamber 141 and an air inlet channel 142. The clothes drying chamber 141 can be used to dry clothes. In this way, the air inlet channel 142 guides the outside airflow to the shell 11 for heat exchange or other treatment before entering the clothes drying chamber 141, thereby improving the drying efficiency.

[0047] In one embodiment, there is a space between the outer periphery of the air guide 15 and the housing 11, and the clothes drying cavity 141 and the air inlet channel 142 are connected through the space. In this way, the external airflow from the air inlet channel 142 can be blown into the clothes drying cavity 141 through the space.

[0048] In one embodiment, please refer to Figure 1 and Figure 3 The drying chamber 141 and the air inlet channel 142 are isolated from each other, and the air guide section 15 has an air outlet 15a that connects the air inlet channel 142 and the drying chamber 141. That is, the outer periphery of the air guide section 15 is connected to the shell 11. In this way, the airflow in the air inlet channel 142 enters the drying chamber 141 more dispersedly through the air outlet 15a, so as to have a larger contact area with the airflow and improve the drying efficiency.

[0049] The specific type of the air outlet 15a is not limited. For example, in one embodiment, please refer to... Figure 1 and Figure 3 The air outlet 15a includes multiple through holes. For example, the air outlet 15a includes through holes arranged in an array. This allows the airflow to be blown into the drying chamber 141 more evenly and dispersed, so that all parts of the clothes in the drying chamber 141 can be dried evenly.

[0050] In one embodiment, the door 11 is provided with an air outlet communicating with the clothes drying chamber 141. By providing an air outlet on the door 11, the humid air from the clothes drying chamber 141 can be discharged, preventing odors and improving the user experience. The air outlet and the blower 15a are located on opposite sides of the clothes drying chamber 141. For example, the blower 15a and the air outlet are located on opposite sides of the clothes, and the airflow path between the blower 15a and the air outlet is roughly straight, reducing airflow bends and ensuring smoother airflow. This effectively promotes the timely removal of humid air to the outside and can reduce noise generated by the airflow to a certain extent.

[0051] In one embodiment, the air inlet channel 142 is arranged around the outer periphery of the clothes drying cavity 141. In this way, the contact area between the airflow in the air inlet channel 142 and the shell 11 is larger and the contact time is longer, resulting in better heat exchange between the external airflow in the air inlet channel 142 and the shell 11.

[0052] As an example, in one embodiment, please refer to Figure 1 and Figure 3 The air inlet channel 142 includes a guide section 1421 and a blowing section 1422. The blowing section 1422 is located on the side of the clothes drying cavity 141 away from the door 11. The guide section 1421 connects the air inlet 14a and the blowing section 1422, and is located below the clothes drying cavity 141. For example, the guide section 1421 extends generally in the front-to-back direction and connects the air inlet 14a and the blowing section 1422, while the blowing section 1422 extends in the vertical direction. The air inlet channel 142 is generally L-shaped. Since the part of the housing 11 away from the door 11 is the concentrated heat exchange area, the guide section 1421 guides the external airflow from the front air inlet 14a to the blowing section 1422, so that the external airflow in the blowing section 1422 can exchange heat with the part of the housing 11 away from the door 11, thereby improving the heat exchange effect.

[0053] As an example, in one embodiment, please refer to Figure 1 and Figure 3 The air outlet 15a is located on the air guide 15 corresponding to the air blowing section 1422. The airflow of the air blowing section 1422 can blow air from the back and top of the clothes, resulting in high drying efficiency.

[0054] As an example, in one embodiment, please refer to Figure 3 The air guide section 15 includes an air inlet plate 151 and an air blower plate 152. The air blower plate 152 is spaced apart from the door body 11. The air inlet plate 151 connects the area surrounding the air inlet 14a and the air blower plate 152. The air inlet plate 151 and the housing 11 form an air guide section 1421, and the air blower plate 152 and the housing 11 form an air blower section 1422. The air outlet 15a is formed on the air blower plate 152. The air outlet 15a is located at the rear of the drying chamber 141. In this way, on the one hand, the external airflow in the air blower section 1422 can exchange heat with the part of the housing 11 away from the door body 11. On the other hand, the external air enters the air inlet channel 142 from the lower air inlet 14a and flows, and then blows into the drying chamber 141 from the rear, which can prolong the contact time between the airflow and the clothes in the drying chamber 141.

[0055] As an example, in one embodiment, please refer to Figure 3The air inlet plate 151 is generally horizontally positioned, and the cross-sectional area of ​​the air guide section 1421 decreases from near the air inlet 14a to away from it. This increases the airflow velocity in the air guide section 1421. The blower plate 152 extends upward from the other end of the air inlet plate 151, and together with the housing 12, forms the blower section 1422. The cross-sectional area of ​​the blower section 1422 can be equal at any position. The airflow from the blower port 15a is relatively uniform, ensuring even drying of all parts of the clothing.

[0056] In one embodiment, the door assembly 1 includes a cover for opening or closing the retrieval opening. The shape of the cover can be adapted to the shape of the retrieval opening; for example, the cover can be plate-shaped, disc-shaped, or other shapes, as long as the cover can cover the retrieval opening. Both the cover and the retrieval opening can be circular, elliptical, square, etc. By covering the retrieval opening with the cover, the gas in the drying chamber 14 can be discharged from the air outlet to the outside of the drying chamber 14.

[0057] The location of the cover is determined by the location of the opening. For example, when the opening is located on the door 11, the cover can also be located on the door 11. One side of the cover can be fixed to the door 11 in a rotatable manner, such as by using a hinge or latch. The other side of the cover can be fixed to the door 11 in a detachable manner, such as by a snap-fit ​​or magnetic attraction. In this way, the user can open the opening by pulling the detachable side of the cover, place clothes into the drying chamber 141, and then push the detachable side of the cover to close the opening, preventing clothes from being blown out of the drying chamber 141 and preventing children or animals from entering the drying chamber 141 through the opening. It is simple to operate and highly safe.

[0058] In one embodiment, the air outlet can be located on the cover. This avoids drilling holes in the door 11, thus improving the overall aesthetics.

[0059] In one embodiment, please refer to Figure 1 and Figure 3 The door assembly 1 includes a suspension 16, which is located on the top side of the drying chamber 14 and is used to hang clothes. In this way, the clothes are more stretched out in the drying chamber 14 under their own weight, and the dried clothes are flatter with fewer wrinkles.

[0060] For example, in one embodiment, the suspension 16 can be located on the top side of the drying chamber 141. Clothes hung on the suspension 16 are suspended relatively uniformly within the drying chamber 141 due to their own weight, reducing the likelihood of folding. Then, by blowing air from the back and top of the clothes, the drying time can be accelerated, resulting in high efficiency. It is understood that some silk garments, such as scarves, shawls, hats, or ties, may be damaged if dried by tumbling the dryer, as the friction between the garment and the dryer may cause damage. Hanging clothes, especially silk or cotton garments, on the suspension 16 can reduce the risk of damage.

[0061] The specific structure and installation method of the suspension 16 are not limited. For example, the suspension 16 may include a clothes drying rod and a connecting rod. The clothes drying rod can be set horizontally, and the connecting rod connects the clothes drying rod and the top surface of the clothes drying cavity 141. In this way, clothes can be hung directly on the clothes drying rod or hung on the clothes drying rod via hangers.

[0062] In one embodiment, please refer to Figure 1 , Figure 2 or Figure 3 The door assembly 1 includes a filter 17 that covers the air inlet 14a. Exemplarily, the filter 17 is disposed on the outer surface of the door 11 to cover the air inlet 14a. The filter 17 is used to filter foreign objects such as dust and / or lint. The filtered airflow enters the drying chamber 14 to prevent foreign objects in the airflow from contaminating the drying chamber 14 and the clothes, and to prevent foreign objects from affecting the operation of the impeller 13. The filter 17 also prevents children or animals from touching the impeller 13, ensuring high safety.

[0063] In one embodiment, please refer to Figure 1 or Figure 3 The door assembly 1 includes a temperature and humidity sensor and a heater 18, both of which are disposed within the drying chamber 14. Exemplarily, the temperature and humidity sensor is located inside the drying chamber 141 near the door 11. The temperature and humidity sensor can be used to detect the temperature and humidity of the airflow within the drying chamber 14. The heater 18 is used to heat the airflow within the drying chamber 14. For example, the temperature and humidity sensor can detect the humidity of the airflow within the drying chamber 141 to determine whether clothes are dried and whether there are clothes in the drying chamber 141, resulting in high automation and a good user experience. The temperature and humidity sensor can also be used to monitor the temperature within the drying chamber 141 to adjust the temperature of the heater 18, resulting in high efficiency, preventing component burnout, and ensuring high safety.

[0064] For example, the heater 18 can be disposed in the air inlet channel 142 and located on the side of the impeller 13 away from the air inlet 14a. In this way, the heater 18 heats the airflow from the air inlet 14a to achieve rapid drying of clothes, saving users' waiting time and providing a better user experience. On the one hand, placing the heater 18 on the side of the impeller 13 away from the air inlet 14a not only maximizes the heating of the airflow in the air inlet channel but also prevents the heater 18 from affecting the filter 17, ensuring safety. For example, if the heater 18 were placed on the side of the impeller 13 close to the air inlet 14a, the heater 18 could easily damage the filter 17 and may even burn the user. On the other hand, when the gas flowing in the air inlet channel 142 is hot air, because hot air has a lower density, it will be lifted upward by the cold air. The air inlet 14a is located below the drying chamber 141, and the blowing section 1422 is located behind the drying chamber 141. This makes it easier for hot air to be delivered to the vicinity of the blowing port 15a, so as to speed up the drying time of clothes, which is convenient, fast and efficient.

[0065] The specific type of heater 18 is not limited. For example, heater 18 includes, but is not limited to, PTC (Positive Temperature Coefficient) heater 18, electromagnetic heater 18, infrared heater 18, resistance heater 18, or heating wire, etc. PTC heater 18 has high heat exchange efficiency and good safety.

[0066] This application also provides a garment processing device; please refer to [link / reference]. Figure 1 The garment handling device 100 includes the door assembly 1 and the drum assembly 2 as described in any embodiment of this application. The garment handling device 100 may be a washing machine, a washer-dryer combo, or a dryer, etc.

[0067] The cylindrical assembly 2 has a clothing inlet and a clothing cavity 21a communicating with the clothing inlet. A door 11 is used to open or close the clothing inlet. One side of the door 11 is rotatably fixed to the cylindrical assembly 2 via a hinge or other means, while the other side of the door 11 is detachably fixed to the cylindrical assembly 2 via a snap-fit ​​or magnetic attraction. Pushing or pulling the door 11 opens or closes the clothing inlet.

[0068] At least a portion of the housing 12 may be located within the clothing cavity 21a. In this way, the drying cavity 14 and the clothing cavity 21a are separated by the housing 12, preventing airflow or water exchange between them and ensuring the cleanliness and hygiene of the drying cavity 14. The fact that at least a portion of the housing 12 is located within the clothing cavity 21a allows for a suitable increase in the volume of the drying cavity 14 to accommodate an appropriate amount of clothing.

[0069] When the garment processing equipment 100 is a washer-dryer combo or a dryer, the garment chamber 21a can be used to dry clothes. Both the garment chamber 21a and the drying chamber 14 are in the drying state. The hot airflow in the garment chamber 21a can be conducted through the housing 12, and the heat from the garment chamber 21a can be used to heat the airflow located in the air inlet channel 142, saving energy and reducing costs. Of course, if the garment processing equipment 100 is a washing machine or other equipment without a drying function, the heater 18 can be used to heat the gas in the air inlet channel 142, which is simple, controllable, and highly efficient.

[0070] The clothing processing device 100 provided in this embodiment can place small items of clothing in the drying chamber 14 to achieve the drying function, so that clothing processing devices 100 without a drying function, such as washing machines, can also achieve the drying effect, which is convenient and efficient. If the clothing processing device 100 is a dryer or a washer-dryer combo, the hot airflow in the clothing chamber 21a can be used to heat the airflow in the drying chamber 14 through the housing 12, saving energy and reducing costs.

[0071] For example, the tube assembly 2 includes an inner tube 21 and an outer tube 22 that are rotatable relative to each other. The outer tube 22 has a clothing inlet, and the inner tube 21 has a clothing cavity 21a. That is, the outer tube 22 remains stationary, while the inner tube 21 can rotate. In this way, the rotation of the inner tube 21 drives the movement of the clothing in the clothing cavity 21a.

[0072] This application also provides a garment processing device; please refer to [link / reference]. Figure 1 The garment processing device 100 includes a door assembly 1, a cylinder assembly 2, a circulating air duct, and an impeller as described in any of the above embodiments. The cylinder assembly 2 has a garment inlet and a garment cavity 21a communicating with the garment inlet. The door 11 is used to open or close the garment inlet. The circulating air duct communicates with the garment cavity 21a. The impeller is disposed in the circulating air duct. The impeller rotates to drive airflow to circulate between the circulating air duct and the garment cavity 21a, thereby drying the garments.

[0073] In some embodiments, the axis of the cylinder assembly 2 may be vertical, such as in the impeller-type garment handling device 100.

[0074] In some embodiments, the axis of the drum assembly 2 may also be horizontal, such as in the drum-type garment handling device 100. In this case, the garment inlet is formed on the front side of the drum assembly 2, for example, the outer drum 22.

[0075] It should be noted that in the embodiments of this application, the front side refers to the side facing the user, and the rear side is the side opposite to the front side.

[0076] In some embodiments, the axis of the cylinder assembly 2 may also be in an inclined direction, such as in the agitator garment processing device 100.

[0077] In some embodiments, the clothing handling device 100 includes a heat exchange assembly and a heat exchange shell located on the bottom side of the cylindrical assembly 2. The heat exchange assembly includes an evaporator and a condenser, both located within the heat exchange shell. Along the airflow direction, the evaporator is located upstream of the condenser. For example, the evaporator and condenser can be finned tube heat exchangers. The refrigerant flows within the evaporator and condenser to exchange heat with the airflow in the circulating duct. That is, in the airflow path of the circulating duct, the airflow first flows through the evaporator and then through the condenser. For example, the evaporator is located in front of the condenser. The humid and cold airflow from the clothing chamber 21a enters the heat exchange shell from the front, first flowing through the evaporator and then through the condenser. The humid and cold airflow from the clothing chamber 21a exchanges heat with the evaporator to dehumidify and form a dry and cold airflow. The dry and cold airflow is heated by the condenser to form a dry and hot airflow. The dry and hot airflow flows back into the clothing chamber 21a, where it again exchanges heat with the wet clothing in the clothing chamber 21a to form a humid and cold airflow.

[0078] In one embodiment, the garment processing device 100 includes a temperature and humidity detector disposed within the drum assembly 2. The humidity detector is used to detect whether the garments are dried and whether there are garments in the garment chamber 21a. It can also monitor the temperature within the garment chamber 21a to facilitate the adjustment of the temperature of the heat exchange assembly, ensuring high safety.

[0079] This embodiment, by setting up the cylinder assembly 2, the circulating air duct, and the impeller, can provide a drying function for the clothes in the clothes chamber 21a. Users can choose to dry large items such as coats in the clothes chamber 21a, and dry small items such as underwear in the drying chamber 14, so as to achieve separate drying of clothes of different materials or different sizes, ensuring cleanliness and hygiene.

[0080] This application also provides a control method for use in the garment processing equipment provided in any embodiment of this application. Please refer to [link to relevant documentation]. Figure 4 The control methods include:

[0081] S1. Start the drying mode.

[0082] Here, buttons can be installed on the garment handling device 100 to activate the drying mode. The specific type of button is not limited; the button can be a physical button or a touch button.

[0083] S2. Turn on the wind turbine and the impeller.

[0084] The buttons are one-button type. For example, when the user presses the button, both the wind turbine 13 and the impeller will enter the working state, reducing the number of user operation steps and providing a good user experience.

[0085] S3. Determine whether there are clothes in the drying chamber and the clothing chamber based on the humidity in the drying chamber and the clothing chamber.

[0086] By activating the drying mode, the impeller 13 and impeller can be turned on with a single button. The impeller 13 drives the airflow in the drying chamber 14, and the impeller drives the airflow in the clothing chamber 21a. The presence of clothing in the drying chamber 14 is determined by whether the humidity in the drying chamber 14 reaches a first threshold. The presence of clothing in the clothing chamber 21a is determined by whether the humidity in the clothing chamber 21a reaches a second threshold.

[0087] The control method provided in this application embodiment allows the user to trigger the drying mode once, so that the clothing handling equipment 100 can automatically determine the condition of the clothes in the drying chamber 14 and the clothing chamber 21a. The user does not need to start the fan wheel 13 and the impeller separately, reducing the user's operation steps.

[0088] In one embodiment, S3, a method for determining whether there are clothes in the drying chamber and the clothing chamber based on the humidity in the drying chamber and the clothing chamber, includes:

[0089] S31. Obtain the first humidity of the drying chamber through the temperature and humidity sensor inside the drying chamber;

[0090] S32. Based on the first humidity level, determine whether there are clothes in the drying chamber.

[0091] For example, a temperature and humidity sensor installed in the drying chamber 14 can be used to obtain the first humidity in the drying chamber 14, and the presence of clothing in the drying chamber 141 can be determined based on whether the first humidity reaches a first threshold.

[0092] Understandably, the first humidity refers to the moisture content of the airflow in the drying chamber 14. The temperature and humidity sensor can detect the moisture content in the drying chamber 14 to determine whether there are clothes present.

[0093] In one embodiment, S32, determining whether there are clothes in the drying chamber based on the first humidity level includes:

[0094] S321. If the first humidity is not less than the first threshold, it is determined that there are clothes in the drying chamber;

[0095] S322. Turn on the heater to heat the airflow in the drying chamber.

[0096] For example, when the first humidity is greater than or equal to the first threshold, it indicates that the moisture content of the airflow in the drying chamber 14 is much greater than the moisture content of the indoor environment, and that there are clothes in the drying chamber 14. Then, the heater 18 is turned on to heat the airflow in the drying chamber 14, thereby reducing the drying time of the clothes and increasing efficiency.

[0097] It should be noted that the specific value of the first threshold can be set according to actual needs. For example, the first threshold can be obtained based on existing technology, which will not be elaborated here.

[0098] In one embodiment, S323, after determining that the temperature in the drying chamber has reached a first set value, the heater is turned off.

[0099] It should be noted that the first setting value can be set by the user or by technicians when the garment processing equipment 100 leaves the factory. The first setting value can be between 35 and 45 degrees Celsius.

[0100] When the temperature and humidity sensor in the drying chamber 14 detects that the temperature of the drying chamber 14 has reached the first set value, the heater 18 will be temporarily turned off even if the clothes are not yet dried, to prevent the temperature in the drying chamber 14 from becoming too high and damaging the clothes. The heater 18 can be restarted after the temperature in the drying chamber 14 reaches a second set value, which is lower than the first set value. This ensures that there is an appropriate temperature range in the drying chamber 14 for drying the clothes. However, the fan wheel 13 continues to rotate during this process until the clothes are completely dried.

[0101] In one embodiment, S324, after determining that the first humidity in the drying chamber has reached the second threshold, the fan and heater are turned off.

[0102] Specifically, the second threshold is less than the first threshold. For example, when the first humidity reaches the second threshold, such as 3%, it indicates that the clothes have been dried, and then the fan 13 and heater 18 can be turned off.

[0103] In one embodiment, S321', if the first humidity is less than a first threshold, it is determined that there are no clothes in the drying chamber, and the fan is turned off.

[0104] In one embodiment, S3, a method for determining whether there are clothes in the drying chamber and the clothing chamber based on the humidity in the drying chamber and the clothing chamber, includes:

[0105] S31', A temperature and humidity detector detects the second humidity in the clothing cavity;

[0106] S32' Determine whether there is clothing in the clothing cavity based on the second humidity level.

[0107] For example, a second humidity level within the clothing cavity 21a is obtained by a temperature and humidity detector disposed within the clothing cavity 21a. It is understood that the second humidity level refers to the moisture content within the clothing cavity 21a, and the temperature and humidity detector can obtain the moisture content within the clothing cavity 21a to determine the presence of clothing.

[0108] In one embodiment, S32', determining whether there is clothing in the clothing cavity based on the second humidity level includes:

[0109] S32'1. If the second humidity is not less than the third threshold, it is determined that there is clothing in the clothing cavity;

[0110] S32'2, Turn on the heat exchange assembly to exchange heat with the airflow in the circulating air duct.

[0111] Here, the airflow in the clothing cavity 21a can conduct heat through the shell 12 to heat the airflow in the air inlet channel 142.

[0112] For example, when the second humidity is greater than or equal to the third threshold, it indicates that there are clothes in the clothing cavity 21a. Then, the heat exchange component is turned on to heat the airflow in the circulating air duct, thereby reducing the drying time of the clothes and making it highly efficient.

[0113] It should be noted that the clothes that need to be dried can be either spun dry or not.

[0114] The specific value of the third threshold can be set according to actual needs, and the specific value of the third threshold can adopt the value in the existing technology, which will not be elaborated here.

[0115] In one embodiment, S32'3, after determining that the second humidity in the clothing cavity has reached a fourth threshold, the impeller and the heat exchange assembly are turned off.

[0116] Specifically, the fourth threshold is less than the third threshold. For example, when the second humidity reaches the fourth threshold, such as 3%, it indicates that the clothes have been dried, and then the impeller and heat exchange assembly can be turned off.

[0117] In one embodiment, S32'1', if the second humidity is less than the third threshold, it is determined that there are no clothes in the clothing chamber, and the impeller is turned off. That is, if there are no clothes to be dried in the clothing chamber, the impeller stops working.

[0118] In some embodiments, the garment handling device 100 includes a first button and a second button. The first button is used to start the drying program of the drying chamber 14, and the second button is used to start the drying program of the garment chamber 21a. That is, after the user places garments into the drying chamber 14, the user can independently trigger the first button to start the drying program of the drying chamber 14. After the user places garments into the garment chamber 21a, the user can independently trigger the second button to start the drying program of the garment chamber 21a. In this way, the drying programs of the drying chamber 14 and the garment chamber 21a can be started separately using the first and second buttons, eliminating the need for the controller of the garment handling device 100 to determine the presence of garments, thus simplifying the control steps of the garment handling device 100.

[0119] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
