Technical Field

[0001] This invention relates to the field of clothing processing technology, and specifically provides a control method for clothing processing equipment and clothing processing equipment. Background Technology

[0002] Existing garment processing equipment mainly includes washer-dryer combos and dryers.

[0003] Taking washer-dryer combos as an example, most existing washer-dryer machines use heat pump drying systems. A heat pump drying system includes a heat pump unit, which comprises a compressor, evaporator, condenser, and refrigerant pipes connecting the compressor to the evaporator and condenser. The evaporator is used to condense and dehumidify the airflow, while the condenser is used to heat the airflow.

[0004] During the drying mode of a washer-dryer combo, the compressor temperature can easily rise, which reduces the efficiency of the heat pump unit and thus affects the drying efficiency of the washer-dryer combo.

[0005] Because washer-dryer combos have many functions, they have a lot of water pipes inside the machine. These pipes are intertwined, making them inconvenient to arrange and maintain.

[0006] As the drying process progresses, the temperature of the evaporator will gradually increase, which will reduce the dehumidification efficiency of the evaporator and affect the drying efficiency. In addition, the amount of lint on the evaporator will gradually increase, which will also affect the drying efficiency.

[0007] The drying equipment mainly includes a housing and a drying drum and drying device installed inside the housing. The drying duct of the drying device is connected to the drying drum. During the drying process, the airflow circulates between the drying duct and the drying drum. The drying duct is located above the drying drum, which has an air outlet. The drying duct is connected to this air outlet. The airflow exiting from the air outlet needs to flow upward first, and then flow horizontally after reaching the top wall of the drying duct. In other words, the airflow needs to make a bend of about 90 degrees after entering the drying duct. At the corner of the drying duct, lint tends to accumulate, affecting the drying efficiency.

[0008] Existing garment processing equipment has a relatively long drying time, which affects the user experience.

[0009] Therefore, there is a need in this field for a new technical solution to address at least one of the above-mentioned problems. Summary of the Invention

The elastic reset member is mounted between the outer casing and the button. When the button is pressed, the elastic reset member is compressed or stretched. When the button is released from pressure, the elastic reset member resets the button. The elastic drive member is mounted between the outer casing and the scraping member, extending along the first direction. When the scraping member is in its initial position, the elastic drive member is compressed or stretched. When the first locking structure separates from the second locking structure, the elastic drive member can push or pull the scraping member to move along the first direction toward the first end of the outer casing; and / or

[0018] The outer casing is provided with a first guide structure, and the handle is provided with a second guide structure. The first guide structure and the second guide structure cooperate to ensure that the handle can only move along the first direction; and / or

The step of "turning on the cooling fan" specifically includes: making the cooling fan run at the first speed; the control method further includes: determining whether the decrease in exhaust temperature is greater than a preset value; if the determination result is "no", then increasing the speed of the cooling fan to the second speed.

[0033] In a preferred embodiment of the above control method, the control method further includes: acquiring the ambient temperature near the cooling fan; determining the rotational speed of the cooling fan based on the ambient temperature; wherein the rotational speed is positively correlated with the ambient temperature.

[0043] By installing a cooling fan near the compressor, the present invention can reduce the temperature of the compressor and prevent it from overheating during the drying process, thereby improving the drying efficiency of the garment processing equipment. In addition, by only turning on the cooling fan to cool the compressor when the preset start-up conditions are met, the drying efficiency can be avoided due to the compressor heating up too slowly, and the energy consumption is also greater.

[0092] Furthermore, the lint collection device of the present invention, by providing a scraping component inside the housing, can push the lint inside the housing toward the air inlet of the housing when it is necessary to clean the lint inside the housing, which facilitates the cleaning of lint, improves the cleaning efficiency of lint, and enhances the user experience. In addition, the scraping component can also scrape off the lint on the filter screen. Moreover, by providing a first component and a second component on the scraping component and the handle respectively, the scraping component can be moved by the attraction between the first component and the second component, without the need for the handle to directly contact the scraping component, which can effectively avoid air leakage and lint leakage.

[0093] Furthermore, by setting a button, the present invention can lock the scraping component in the initial position to prevent the scraping component from moving automatically. By setting an elastic reset component between the housing and the button, the button can be automatically reset and the first locking structure on the button and the second locking structure on the scraping component can be prevented from automatically separating. By setting an elastic drive component between the scraping component and the housing, the scraping component can be automatically driven to move after the button is pressed, thereby improving the user experience.

[0094] Furthermore, the present invention guides the handle by setting a first guide structure and a second guide structure, which facilitates the operation of the handle to move with the scraping component and prevents the handle from deviating.

[0095] Furthermore, by providing a guide rod on the outer shell and a guide cylinder adapted to the guide rod on the scraping member, the present invention can prevent the scraping member from shifting during movement. In addition, by sleeved the elastic drive member on the guide rod, it is easier to drive the scraping member to move, resulting in better reliability.

[0107] Furthermore, by using water spray pipes to spray water towards the inner wall of the drying duct, the structure is simple, easy to arrange, and low in cost.

[0108] Furthermore, by setting air inlets and outlets on the sides of the casing of the lint filter device along its length and width respectively, the flow direction of the airflow entering the casing can be changed, making it more compatible with the arrangement of the drying duct.

[0109] Furthermore, by setting the second filter screen between the air inlet and the first filter screen to be arc-shaped, it is beneficial to increase the filtration area of ​​the second filter screen, thereby improving the filtration effect of the lint filter device.

[0110] Furthermore, by configuring the mounting bracket to be able to be pulled out from the air inlet of the housing, the lint filtered by the second filter can be scraped off through the mounting bracket when it is removed.

[0111] Furthermore, by enclosing the first frame, the second frame, and the connecting plate of the mounting bracket, the mounting bracket can achieve a better effect in scraping off wire debris when disassembling the mounting bracket.

[0112] Furthermore, by setting up a second flushing device to flush the evaporator, it is possible to prevent lint from accumulating in the evaporator and to cool the evaporator.

[0116] In the preferred embodiment of the above-mentioned garment processing equipment, the second filter screen is arc-shaped and protrudes towards the first filter screen; and / or

[0117] The lint filter also includes a mounting bracket detachably mounted inside the housing, the mounting bracket being removable from the air inlet, and the second filter screen being disposed on the mounting bracket.

[0118] In the preferred embodiment of the above-mentioned garment processing equipment, the mounting frame includes a first frame, a second frame, and a connecting plate. The first end of the first frame is connected to the first end of the second frame, and the second end of the first frame and the second end of the second frame are connected by the connecting plate. The first frame is located at the air inlet, the second filter screen is disposed on the second frame, and the connecting plate is disposed opposite to the second side.

[0119] In the preferred embodiment of the above-mentioned garment processing equipment, the lint filter is detachably installed in the drying duct. The drying duct has an insertion interface on the side facing the front panel of the housing. The lint filter is inserted into the drying duct through the insertion interface. The front panel has a disassembly port at a position opposite to the insertion interface, and the lint filter can be pulled out from the disassembly port.

[0120] In the preferred embodiment of the above-mentioned garment processing equipment, a first annular sealing member is provided at one end of the lint filter near the insertion interface, and a second annular sealing member is provided at the other end of the lint filter. Both the first and second annular sealing members are sealed and fitted against the inner wall of the drying duct. The outer diameter of the second annular sealing member is smaller than the outer diameter of the first annular sealing member; and / or

[0121] The inner wall of the drying air duct is provided with a blocking and positioning structure at a position away from the insertion interface. The blocking and positioning structure abuts against the lint filter to position the lint filter in a set installation position.

[0122] In the preferred embodiment of the above-mentioned garment processing equipment, the garment processing equipment further includes an air inlet pipe and an air outlet pipe. A fresh air inlet is provided on the drying duct, and the fresh air inlet is connected to one end of the air inlet pipe. The other end of the air inlet pipe is connected to an air inlet on the back panel of the housing. A fresh air outlet is provided on the garment processing drum, and the fresh air outlet is connected to one end of the air outlet pipe. The other end of the air outlet pipe is connected to the drain pipe of the garment processing equipment; and / or

[0123] The lowest point of the air outlet is higher than the center point of the air outlet port.

[0124] In the preferred embodiment of the above-mentioned clothing processing equipment, the drying air duct includes a first air duct and a second air duct that are connected to each other. The first air duct and the second air duct are located above the clothing processing drum. The first air duct extends in the front-to-back direction, and the second air duct extends in the left-to-right direction and is close to the front end of the clothing processing drum. The air inlet is located in the first air duct, and the air outlet is located in the second air duct. The lint filter is installed in the first air duct. The drying equipment also includes a heat pump module. The evaporator and condenser of the heat pump module are installed in the second air duct, and the evaporator is located upstream of the condenser.

[0125] In the preferred embodiment of the above-mentioned clothing processing equipment, the clothing processing equipment further includes a condensate pipe, and the second air duct is provided with a drain outlet at a position corresponding to the evaporator. The drain outlet is connected to the drain pump or drain pipe of the clothing processing equipment through the condensate pipe.

[0126] When the above technical solution is adopted, the present invention positions the air outlet of the lint filter device higher than the air outlet of the drying duct. In this way, the airflow in the drying duct flows downward at an angle towards the air outlet, which helps to reduce the resistance to the airflow. The less resistance the airflow experiences, the smoother the airflow, which helps to improve drying efficiency and reduce drying time. In addition, the fan blows air directly into the clothes processing drum, resulting in stronger airflow, which also helps to improve drying efficiency.

[0127] Furthermore, by making the lowest point of the air outlet of the lint filter higher than the center point of the air outlet of the drying duct, the airflow resistance is reduced and the drying efficiency is increased.

[0128] Furthermore, by setting air inlets and outlets on the sides of the casing of the wire lint filter device along its length and width respectively, the flow direction of the airflow entering the casing can be changed, making it easier to arrange the wire lint filter device.

[0129] Furthermore, by setting the second filter screen between the air inlet and the first filter screen to be arc-shaped, it is beneficial to increase the filtration area of ​​the second filter screen, thereby improving the filtration effect of the lint filter device.

[0130] Furthermore, by configuring the mounting bracket to be able to be pulled out from the air inlet of the housing, the lint filtered by the second filter can be scraped off through the mounting bracket when it is removed.

[0131] Furthermore, by enclosing the first frame, the second frame, and the connecting plate of the mounting bracket, the mounting bracket can achieve a better effect in scraping off wire debris when disassembling the mounting bracket.

[0132] Furthermore, by setting a blocking positioning structure in the drying air duct at a position away from the insertion interface, when installing the lint filter, the user pushes the lint filter forward along the drying air duct until the lint filter comes into contact with the blocking positioning structure in the drying air duct and can no longer be pushed. This indicates that the lint filter has been installed in the set installation position. This helps to prevent the lint filter from being installed in the wrong position.

[0133] Furthermore, by making the outer diameter of the second annular sealing member located at the inner end smaller than the outer diameter of the first annular sealing member located at the outer end, the friction between the lint filter and the drying air duct can be reduced during both installation and disassembly of the lint filter, making it more labor-saving and more conducive to the installation and disassembly of the lint filter.

[0134] Furthermore, by connecting the air inlet pipe and the air outlet pipe to the drying duct and the clothes handling drum respectively, fresh air from outside can enter the clothes handling drum during the drying process. This fresh air is relatively dry, and some of the humid air can also be discharged to the outside. This setup is very effective in reducing the humidity of the airflow, thereby reducing the drying time of the clothes handling equipment. In addition, the humid airflow is guided to the drain pipe through the exhaust pipe and discharged directly into the floor drain, avoiding accumulation near the clothes handling equipment and further reducing the drying time of the clothes handling equipment.

[0135] Furthermore, by connecting the drain outlet on the drying duct to the drain pump or drain pipe of the garment processing equipment via a condensate drain pipe, the condensate water does not enter the garment processing drum. Instead, it is discharged directly to the floor drain through the drain pipe, thus avoiding any impact on drying efficiency and providing a better drainage solution. In addition, since the condensate drain pipe is not connected to the garment processing drum, it is not affected by pressure fluctuations inside the drum, which facilitates the smooth discharge of condensate water.

Detailed Implementation

[0174] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. For example, although the embodiments described below are introduced in conjunction with a washer-dryer combo, the technical solutions of the present invention are equally applicable to other types of clothing processing equipment, such as dryers.

[0175] It should be noted that in the description of this invention, terms such as "left" and "right," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0176] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0177] Example 1

[0178] Specifically, the present invention provides a washer-dryer combo, as shown in Figures 1 and 2. The washer-dryer combo of the present invention includes a housing 1 and a clothes handling drum and a drying system installed in the housing 1. The drying system can deliver hot air to the clothes handling drum to dry the clothes in the clothes handling drum.

[0179] The garment handling drum includes an outer drum 2 and an inner drum that is rotatably installed in the outer drum 2. The drying system is directly connected to the outer drum 2. The inner drum is used to hold clothes. The inner drum wall is provided with multiple through holes. When the drying mode is executed, the through holes can be used for ventilation. When the washing mode is executed, the through holes can be used for water flow.

[0180] Preferably, as shown in Figures 1 to 4, the drying system of the present invention includes a drying device, which includes a drying duct 31, a fan 32, and a heat pump module. The air inlet 3111 of the drying duct 31 is connected to one end of the outer cylinder 2, the air outlet 3121 of the drying duct 31 is connected to the air intake of the fan 32, and the air exhaust port of the fan 32 is connected to the other end of the outer cylinder 2. The evaporator 33 and the condenser 34 of the heat pump module are installed in the drying duct 31, with the evaporator 33 located upstream of the condenser 34.

[0181] The heat pump module also includes a compressor 35, a refrigerant pipe 38 connecting the evaporator 33 and the condenser 34 to the compressor 35, and a throttling element installed on the refrigerant pipe 38. The compressor 35 is located outside the drying duct 31.

[0182] For example, the drying air duct 31 is located above the outer cylinder 2. An air outlet is provided on the cylinder wall of the outer cylinder 2. The air outlet is close to the rear end of the outer cylinder 2. A window gasket 22 is installed at the cylinder opening of the outer cylinder 2. A return air port is provided on the window gasket 22. The air inlet 3111 of the drying air duct 31 is connected to the air outlet through a corrugated pipe 36. The exhaust port of the fan 32 is connected to the return air port through a rubber pipe 37.

[0183] When the drying mode is executed, the fan 32 is started, and the humid air in the clothes handling drum is discharged through the air outlet and enters the drying air duct 31. After being condensed and dehumidified by the evaporator 33, it is heated by the condenser 34 and then flows back to the clothes handling drum from the return air outlet, completing one cycle.

[0184] It should be noted that the present invention is not limited to placing the drying air duct 31 above the clothes processing drum. For example, the drying air duct 31 can also be placed below or behind the outer drum 2. Such adjustments and changes to the specific installation position of the drying air duct 31 do not deviate from the principle and scope of the present invention. Of course, the present invention preferably places the drying air duct 31 above the clothes processing drum, which is beneficial to make full use of the space above the clothes processing drum and optimize the layout.

[0185] Furthermore, it should be noted that those skilled in the art can also interchange the positions of the air outlet and the air return outlet on the outer cylinder 2, such as air outlet at the front end and air inlet at the rear end of the clothing treatment cylinder. Alternatively, the air outlet can be located on the rear wall of the outer cylinder 2, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0186] Furthermore, it should be noted that those skilled in the art can also connect the air intake of the fan 32 to the air outlet on the clothes processing drum, and then connect the exhaust port of the fan 32 to the air inlet 3111 of the drying duct 31. Alternatively, the drying duct 31 can be set into two sections, with the fan 32 installed between the two sections. Or, the fan 32 can be directly installed inside the drying duct 31, etc. Such adjustments and changes to the installation position of the fan 32 do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0187] Preferably, as shown in Figures 3 and 4, the drying system of the present invention further includes a cooling fan 39 for blowing air toward the compressor 35.

[0188] By directing the cooling fan 39 towards the compressor 35, the temperature of the compressor 35 can be prevented from becoming too high, which helps to improve drying efficiency.

[0189] Preferably, as shown in Figures 3 and 4, there is a gap between the cooling fan 39 and the compressor 35.

[0190] In other words, the cooling fan 39 does not contact the compressor 35, and there is a certain gap between them. This facilitates the smooth flow of air around the compressor 35, which helps to cool the compressor 35.

[0191] It should be noted that the present invention does not limit the specific value of the distance between the cooling fan 39 and the compressor 35. For example, the distance between the two can be set to 2cm, 3cm, 5cm, 7cm, 8cm, 10cm, 12cm, 13cm or 15cm, etc.

[0192] The present invention preferably places the distance between the cooling fan 39 and the compressor 35 at 5cm to 10cm. This ensures that there is sufficient distance between them for smooth airflow, while avoiding excessive lateral space occupation.

[0193] Preferably, as shown in Figures 3 and 4, there is a gap between the side wall of the compressor 35 and the drying air duct 31.

[0194] In other words, the drying air duct 31 does not contact the side wall of the compressor 35, and there is a certain gap between them. This makes it easier for the air around the compressor 35 to flow smoothly, which is more conducive to cooling the compressor 35.

[0195] It should be noted that the present invention does not limit the specific value of the distance between the drying air duct 31 and the side wall of the compressor 35. For example, the distance between the two can be set to 1cm, 2cm, 3cm, 4cm or 5cm, etc.

[0196] In this invention, the distance between the side wall of the compressor 35 and the drying air duct 31 is preferably 1cm to 3cm.

[0197] Preferably, as shown in Figures 1 and 3, the cooling fan 39 is fixedly mounted on the housing 1. Further, the cooling fan 39 is fixedly connected to the back of the housing 1.

[0198] Preferably, as shown in Figures 2 to 4, the drying system of the washer-dryer of the present invention further includes a lint collection device 4, which is installed in the drying air duct 31.

[0199] The lint collection device 4 is used to filter the airflow entering the drying duct 31. When the airflow in the drying duct 31 flows through the lint collection device 4, the lint and other impurities carried by the airflow are intercepted by the lint collection device 4. The filtered lint is stored in the lint collection device 4. The lint collection device 4 is preferably located upstream of the evaporator 33.

[0200] Preferably, as shown in Figures 2 to 4, the lint collection device 4 of the present invention is detachably installed in the drying air duct 31. The drying air duct 31 is provided with an insertion interface 3112, and the lint collection device 4 is inserted into the drying air duct 31 through the insertion interface 3112.

[0201] When it is necessary to clean the lint in the lint collection device 4, the lint collection device 4 can be removed from the drying air duct 31. A pressure sensor can be installed upstream and downstream of the lint collection device 4. The pressure difference between the two sensors determines whether the lint collection device 4 needs cleaning. When cleaning is required, a prompt message can be sent to the user to remind them to clean the lint collection device 4.

[0202] It should be noted that, in practical applications, those skilled in the art can place the connector 3112 on the side of the drying duct 31, or on the top surface of the drying duct 31, etc. Such adjustments and changes to the specific location of the connector 3112 do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0203] Preferably, as shown in Figures 1 and 4, the drying air duct 31 is provided with an insertion interface 3112 on the side facing the front panel of the housing 1, and the front panel is provided with a disassembly port 11 at the position opposite to the insertion interface 3112, so that the lint collection device 4 can be pulled out from the disassembly port 11.

[0204] When it is necessary to clean the lint collection device 4, the user can pull out the lint collection device 4 from the disassembly port 11 on the front panel of the housing 1 for easy operation. After cleaning the lint collection device 4, the user can then insert the lint collection device 4 back in through the disassembly port 11.

[0205] Preferably, as shown in Figures 1 to 4, the drying duct 31 of the present invention includes a first duct 311 and a second duct 312 that are connected to each other. The first duct 311 extends in the front-to-back direction, and the second duct 312 extends in the left-to-right direction and is close to the front end of the clothes processing drum. The air inlet 3111 of the drying duct 31 is located in the first duct 311, and the air outlet 3121 of the drying duct 31 is located in the second duct 312. The lint collection device 4 is installed in the first duct 311, and the evaporator 33 and condenser 34 of the heat pump module are installed in the second duct 312.

[0206] For example, both the first air duct 311 and the second air duct 312 are located above the outer cylinder 2. The first air duct 311 is located at the upper left of the outer cylinder 2 and extends from the rear end of the outer cylinder 2 to the front end. An air inlet port 3111 is provided on the bottom wall of the rear end of the first air duct 311. An air outlet on the outer cylinder 2 is located directly below the air inlet port 3111. The air outlet is connected to the upper air inlet port 3111 through a corrugated pipe 36. An insertion interface 3112 is provided at the front end of the first air duct 311. The lint collection device 4 is inserted into the first air duct 311 from the front end of the first air duct 311. The left end of the second air duct 312 is connected to the first air duct 311. An air outlet port 3121 is provided at the right end of the second air duct 312. A fan 32 is located at the upper right of the outer cylinder 2. The air inlet of the fan 32 is connected to the air outlet port 3121 on the second air duct 312.

[0207] It should be noted that, in practical applications, those skilled in the art may also place the first air duct 311 in the upper right of the garment processing drum, and correspondingly place the fan 32 in the upper left of the garment processing drum. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0208] Of course, the present invention preferably places the first air duct 311 in the upper left corner of the outer cylinder 2. A detergent dispensing device is generally provided in the upper left corner. The present invention preferably places the first air duct 311 directly above the detergent dispensing device.

[0209] Preferably, as shown in Figures 5 and 6, the lint collection device 4 of the present invention includes a housing 41 and a filter screen installed on the housing 41. The housing 41 has an air inlet 411 at a first end along a first direction, and an air outlet 412 between the first end and the second end of the housing 41. The filter screen is installed at the air outlet 412.

[0210] For example, the outer shell 41 is a cuboid structure, with the first direction being the length direction of the outer shell 41. The first end of the outer shell 41 has an air inlet 411, and the second end of the outer shell 41 is sealed. An air outlet 412 is located on the side plate between the first end and the second end. A filter screen is installed at the air outlet 412. After the airflow enters the first air duct 311, it enters the outer shell 41 from the air inlet 411, and then exits from the air outlet 412 and enters the second air duct 312. When the airflow passes through the filter screen at the air outlet 412, the lint carried by the airflow is intercepted by the filter screen and remains inside the outer shell 41.

[0211] Preferably, as shown in Figures 5 to 9, the lint collection device 4 of the present invention further includes a scraping component located at the second end of the housing 41. The scraping component is movable in a first direction toward the first end of the housing 41 to push the lint inside the housing 41 toward the air inlet 411.

[0212] By providing a scraping component inside the housing 41, when it is necessary to clean the lint inside the housing 41, the scraping component can push the lint inside the housing 41 toward the air inlet 411 of the housing 41, which facilitates the cleaning of lint, improves the cleaning effect of lint, and enhances the user experience. In addition, as the scraping component moves toward the first end of the housing 41, it can also scrape off the lint on the filter screen.

[0213] Preferably, as shown in Figures 5 to 9, the scraping assembly of the present invention includes a scraping member 42 and a handle 43. The scraping member 42 is located inside the housing 41, and a first member 44 (see Figure 7) is provided on the scraping member 42. The handle 43 is located outside the housing 41, and a second member 45 (see Figure 7) is provided on the handle 43. At least one of the first member 44 and the second member 45 has magnetic force so that the first member 44 and the second member 45 attract each other, thereby enabling the handle 43 to drive the scraping member 42 to move along a first direction toward the first end of the housing 41, thereby causing the scraping member 42 to push the lint inside the housing 41 toward the air inlet 411.

[0214] In other words, the handle 43 does not contact the scraping member 42. This eliminates the need to make holes in the housing 41 to connect the handle 43 and the scraping member 42. This design avoids air leakage, which helps ensure drying efficiency and prevents lint from leaking out.

[0215] For example, the edge of the scraping member 42 is attached to the inner wall of the housing 41, and the handle 43 is located on the top surface of the housing 41. As the handle 43 moves with the scraping member 42, the scraping member 42 pushes the wire debris inside the housing 41 toward the air inlet of the housing 41. By making the edge of the scraping member 42 attached to the inner wall of the housing 41, it is beneficial to clean the wire debris inside the housing 41.

[0216] It should be noted that the present invention does not limit the specific structural form of the scraping member 42. For example, the scraping member 42 can be set as a plate structure, a block structure, or a frame structure, etc.

[0217] Furthermore, it should be noted that, in practical applications, those skilled in the art can set one of the first component 44 and the second component 45 as a magnet or electromagnet, and set the other of the first component 44 and the second component 45 as a metal component (such as an iron block) capable of generating an attractive force with a magnet. Alternatively, both the first component 44 and the second component 45 can be set as magnets or electromagnets, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0218] Preferably, as shown in FIG7, both the first component 44 and the second component 45 are magnets.

[0219] By setting both the first component 44 and the second component 45 as magnets, the attraction between the first component 44 and the second component 45 is stronger, which helps the handle 43 to move smoothly with the scraping component 42.

[0220] Preferably, as shown in Figures 7 and 8, the scraping member 42 of the present invention is provided with a first receiving and limiting groove 423 on the side facing the handle 43, and a first member 44 is located in the first receiving and limiting groove 423. The handle 43 is provided with a second receiving and limiting groove on the side facing the scraping member 42, and a second member 45 is located in the second receiving and limiting groove.

[0221] By installing the first component 44 and the second component 45 in the first receiving limiting groove 423 and the second receiving limiting groove respectively, it is possible to prevent the first component 44 from moving relative to the scraping component 42 and to prevent the second component 45 from moving relative to the handle 43, which is more conducive to the smooth movement of the handle 43 with the scraping component 42.

[0222] For example, the handle 43 is located above the scraping member 42, the first receiving and limiting groove 423 is provided on the top of the scraping member 42, the first receiving and limiting groove 423 is a rectangular groove, and a rectangular magnet block (i.e., the first member 44) is installed in the first receiving and limiting groove 423. The second receiving and limiting groove is provided on the lower surface of the handle 43, the second receiving and limiting groove is also a rectangular groove, and a rectangular magnet block (i.e., the second member 45) is also installed in the second receiving and limiting groove.

[0223] Preferably, as shown in Figures 5 and 9, the outer casing 41 is provided with a first guide structure 414, and the handle 43 is provided with a second guide structure 431. The first guide structure 414 and the second guide structure 431 cooperate to enable the handle 43 to reciprocate only in the first direction.

[0224] The handle 43 is guided and limited by the first guide structure 414 and the second guide structure 431, which facilitates the operation of the handle 43.

[0225] For example, the first guide structure 414 is disposed on the top of the housing 41. With the cooperation of the first guide structure 414 and the second guide structure 431, the handle 43 can only move along the length direction of the housing 41, and cannot move along the width direction of the housing 41 or along the height direction of the housing 41.

[0226] It should be noted that the present invention does not limit the specific structural form of the first guide structure 414 and the second guide structure 431. For example, the first guide structure 414 and the second guide structure 431 can be configured as a structure in which the guide groove and the guide rib cooperate, or as a structure in which the guide rod and the guide hole cooperate, or as a structure in which the guide groove and the guide post cooperate, etc.

[0227] Preferably, as shown in Figures 5 and 9, a strip-shaped groove 415 is provided on the top of the outer shell 41. The strip-shaped groove 415 extends along a first direction. The first guide structure 414 is a guide groove formed on the side wall of the strip-shaped groove 415. The guide groove extends along the first direction. The second guide structure 431 is a guide rib adapted to the guide groove. The guide rib is inserted into the guide groove.

[0228] For example, a strip groove 415 is formed on the upper surface of the housing 41 and extends along the length of the housing 41. A guide groove is formed on each of the two side walls of the strip groove 415. A guide rib is provided on each side of the handle 43, and the two guide ribs are respectively inserted into the corresponding guide grooves.

[0229] Preferably, as shown in Figures 5 to 7, the scraping assembly of the present invention further includes a button 46 mounted on the housing 41. The button 46 is provided with a first locking structure 461, and the scraping member 42 is provided with a second locking structure 422. The first locking structure 461 and the second locking structure 422 cooperate to lock the scraping member 42 in the initial position.

[0230] By setting button 46, it is possible to prevent the scraping component 42 from moving automatically in the first direction.

[0231] For example, a mounting hole is provided on the top of the housing 41, and a mounting cavity 416 is provided inside the housing 41 (see Figure 7). The mounting cavity 416 is located directly below the mounting hole. The button 46 is inserted vertically into the mounting cavity 416 through the mounting hole. The top surface of the button 46 is basically flush with the top surface of the housing 41. When it is necessary to scrape off the lint inside the housing 41 by using the scraping member 42, the button 46 is pressed down to separate the first locking structure 461 on the button 46 from the second locking structure 422 on the scraping member 42. Then, the scraping member 42 can be moved along the first direction by the handle 43.

[0232] It should be noted that in order to prevent air leakage at the mounting hole, a sealing structure needs to be set. For example, a rubber sleeve can be installed on the top of button 46, and the rubber sleeve can be sealed and fitted to the inner wall of the mounting hole, etc.

[0233] Furthermore, it should be noted that the present invention does not limit the structural form of the first locking structure 461 and the second locking structure 422. For example, it can be configured as a structure in which the lock hook and the lock hole cooperate, or as a structure in which two lock hooks cooperate, etc. Such adjustments and changes to the specific structural forms of the first locking structure 461 and the second locking structure 422 do not deviate from the principle and scope of the present invention, and should all be limited to the protection scope of the present invention.

[0234] Preferably, as shown in FIG7, the first locking structure 461 is a first locking hook, and the second locking structure 422 is a second locking hook that cooperates with the first locking hook.

[0235] For example, the button 46 is provided with two first hooks, which are distributed vertically at intervals and both facing upwards. The scraping member 42 is provided with two second hooks, which are distributed vertically at intervals and both facing downwards. The two first hooks hook the corresponding second hooks respectively.

[0236] Preferably, as shown in FIG7, the scraping assembly of the present invention further includes an elastic reset member 47 installed between the housing 41 and the button 46. After the button 46 is pressed, the elastic reset member 47 is compressed or stretched, and the elastic reset member 47 resets the button 46 after the button 46 is released from pressing.

[0237] For example, the elastic reset member 47 is configured as a vertical spring. A limiting post 417 is provided on the bottom wall of the mounting cavity 416 of the housing 41. The bottom end of the button 46 is provided with a slot 462, which extends along the length of the button 46. The elastic reset member 47 is inserted into the slot 462. The top end of the elastic reset member 47 abuts against the top wall of the slot 462, and the bottom end of the elastic reset member 47 is sleeved on the limiting post 417 and abuts against the bottom wall of the mounting cavity 416. When the user presses the button 46 down, the button 46 moves vertically downward, and the elastic reset member 47 is compressed. When the user stops pressing the button 46, the elastic reset member 47 pushes the button 46 upward, so that the button 46 is reset.

[0238] It should be noted that the elastic reset component 47 is not limited to the spring mentioned above. For example, it can also be set as a rubber column or an elastic rope. If it is an elastic rope, the top end of the elastic rope can be fixedly connected to the inner wall of the outer casing 41, and the bottom end of the elastic rope can be fixedly connected to the button 46. When the button 46 is pressed down, the elastic rope is stretched. After the button 46 is released, the elastic rope contracts, thereby resetting the button 46. Such adjustments and changes to the specific structural form of the elastic reset component 47 do not deviate from the principle and scope of the present invention and should all be limited to the protection scope of the present invention.

[0239] Preferably, as shown in Figures 6 and 8, the scraping member 42 of the present invention is provided with a guide cylinder 421, and the outer shell 41 is provided with a guide rod 413 adapted to the guide cylinder 421. The guide rod 413 extends along a first direction, and the guide cylinder 421 is sleeved on the guide rod 413. The guide cylinder 421 and the guide rod 413 are guided and cooperated to guide the scraping member 42 during its movement along the first direction.

[0240] For example, three guide rods 413 are provided on the outer shell 41, two of which are located at the top, near the top of the outer shell 41 and spaced apart along the width direction of the outer shell 41, and the remaining guide rod 413 is located at the bottom, near the inner bottom wall of the outer shell 41 and in the middle of the inner bottom wall. That is, the three guide rods 413 are distributed in an inverted triangular shape. The number of guide cylinders 421 is also three, and the distribution is the same as that of the guide rods 413, that is, they are also distributed in an inverted triangular shape.

[0241] It should be noted that, in practical applications, those skilled in the art can also arrange the three guide cylinders 421 and the three guide rods 413 in a triangular pattern. Furthermore, the number of guide cylinders 421 and the number of guide rods 413 are not limited to the three mentioned above. For example, they can also be set to one, two, or four, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0242] During the movement of the scraping component 42 along the first direction, the guide cylinder moves along the length of the guide rod to prevent the scraping component 42 from shifting.

[0243] Preferably, as shown in FIG6, the scraping assembly of the present invention further includes an elastic driving member 48 disposed between the scraping member 42 and the housing 41. The elastic driving member 48 extends along a first direction. When the scraping member 42 is in the initial position, the elastic driving member 48 is compressed or stretched. When the first locking structure 461 on the button 46 is separated from the second locking structure 422 on the scraping member 42, the elastic driving member 48 can push or pull the scraping member 42 to move along the first direction toward the first end of the housing 41.

[0244] In other words, when button 46 is pressed, the scraping member 42 can also move along the first direction under the action of the elastic drive member 48.

[0245] For example, the elastic drive member 48 is configured as a spring, which is sleeved on the guide rod 413. The elastic drive member 48 is located between the guide cylinder 421 and the outer shell 41, specifically between the second end of the guide cylinder 421 and the outer shell 41. The two ends of the elastic drive member 48 abut against the guide cylinder 421 and the outer shell 41, respectively. When the scraping member 42 is in the initial position, the elastic drive member 48 is in a compressed state. After the user presses down the button 46, the first locking structure 461 on the button 46 separates from the second locking structure 422 on the scraping member 42, and the elastic drive member 48 pushes the scraping member 42 to move toward the first end of the outer shell 41.

[0246] It should be noted that, in practical applications, those skilled in the art can also place the elastic drive member 48 between the guide cylinder 421 and the first end of the housing 41. In this case, when the scraping member 42 is in the initial position, the elastic drive member 48 is in a stretched state. After the user presses down the button 46, the first locking structure 461 on the button 46 separates from the second locking structure 422 on the scraping member 42, and the elastic drive member 48 pulls the scraping member 42 toward the first end of the housing 41.

[0247] Furthermore, it should be noted that the elastic drive member 48 is not limited to the spring described above; for example, it can also be an elastic member such as a rubber column, a rubber sleeve, or an elastic rope. Of course, the present invention preferably uses a spring as the elastic drive member 48.

[0248] Furthermore, it should be noted that when multiple guide rods 413 are provided, it is preferable to sleeve an elastic driving member 48 on each guide rod 413. For example, there are three guide rods 413 and three elastic driving members 48, which are respectively sleeved on the corresponding guide rods 413. Such flexible adjustment and change do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0249] Preferably, as shown in Figures 5, 11 and 12, the drying system of the present invention further includes a water spraying device, at least a portion of which is installed in the drying air duct 31 and is capable of spraying water into the drying air duct 31.

[0250] The water spraying device can spray water towards the inner wall of the drying duct 31 to wash away the lint inside the drying duct 31, or it can spray water towards the evaporator 33 to wash away the lint on the evaporator 33, and it can also reduce the temperature of the evaporator 33, etc. Such adjustments and changes to the specific use of the water spraying device do not deviate from the principles and scope of the present invention, and should all be limited to the protection scope of the present invention.

[0251] Preferably, as shown in Figures 5, 11 and 12, the water spraying device of the present invention includes a first water spraying component 51 and a second water spraying component 52. The first water spraying component 51 is disposed near the air inlet port 3111 of the drying air duct 31 and is used to spray water to dry the lint in the drying air duct 31. The second water spraying component 52 is disposed near the evaporator 33 and is used to spray water toward the evaporator 33.

[0252] For example, the first water spray component 51 is installed in the first air duct 311 and sprays water toward the inner wall of the first air duct 311 to wash away the lint located near the air inlet port 3111 and prevent the lint from accumulating in the air inlet port 3111. The second water spray component 52 is installed in the second air duct 312 and sprays water toward the evaporator 33. It is mainly used to cool the evaporator 33 and can also wash away the lint attached to the evaporator 33.

[0253] It should be noted that, in practical applications, those skilled in the art can set the first water spraying component 51 and the second water spraying component 52 to spray water independently, or they can set them to spray water simultaneously, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0254] Furthermore, it should be noted that the present invention does not limit the specific structural form of the first water spraying component 51 and the second water spraying component 52. For example, it can be configured as a water spraying pipe, or as a water spraying box, or as a water channel formed on the drying air duct 31, etc.

[0255] Preferably, as shown in Figures 5 and 11, the first water spraying component 51 of the present invention is a water spraying pipe, a part of which is inserted into the drying air duct 31, and a water spraying nozzle 511 is provided on the water spraying pipe.

[0256] For example, the water spray pipe is provided with a connecting ear 512, which is fixedly connected to the first air duct 311 by bolts. The external port of the water spray pipe is connected to a water supply pipe, and a solenoid valve is provided on the water supply pipe. When water spraying is required, the solenoid valve is turned on, and water is supplied to the water spray pipe through the water supply pipe.

[0257] Preferably, as shown in Figures 5 and 12, the second water spray component 52 of the present invention includes a housing 521 and a plurality of spray holes 522 disposed on the housing 521. The housing 521 is located above the evaporator 33. The top of the housing 521 is open and sealed to the inner top wall of the drying air duct 31. The plurality of spray holes 522 are distributed at intervals along the length direction of the housing 521.

[0258] For example, the housing 521 is fixedly connected to the inner top wall of the second air duct 312. The top of the second air duct 312 is provided with a first connector pipe 53 (see Figure 2 for details). One end of the first connector pipe 53 is inserted into the second air duct 312 and communicates with the housing 521 of the second water spray component 52. The other end of the first connector pipe 53 is connected to a water supply pipe. A solenoid valve is provided on the water supply pipe. When water spraying is required, the solenoid valve is turned on, and water is supplied to the housing 521 through the water supply pipe. The water in the housing 521 is sprayed onto the evaporator 33 through the spray hole 522.

[0259] Preferably, as shown in FIG13, the washer-dryer of the present invention further includes a dispensing device 6 installed in the housing 1, wherein the dispensing device 6 is connected to the outer drum 2 and is used to dispense clothing treatment agent.

[0260] When the washer-dryer is running a washing program, a garment treatment agent, such as detergent or fabric softener, can be added to the inner drum through the dispensing device 6.

[0261] For example, the dispensing device 6 is disposed between the outer cylinder 2 and the drying air duct 31, specifically between the outer cylinder 2 and the first air duct 311. That is, the dispensing device 6 is located directly below the lint collection device 4. The user can also pull the dispensing device 6 out of the housing 1 through the disassembly port 11 on the front panel and then add laundry detergent to the dispensing device 6. Of course, in practical applications, those skilled in the art can also provide a separate disassembly port for the lint collection device 4 and the dispensing device 6 respectively.

[0262] Preferably, as shown in Figure 15, the dispensing device 6 is provided with a water inlet, a first water channel 611 and a first water outlet. The water inlet is connected to a water source, the first water channel 611 is connected to the water inlet and the first water outlet, and the first water outlet is connected to the outer cylinder 2.

[0263] For example, the dispensing device 6 includes a water box 63 and a top cover 61. The water box 63 has a chamber for containing laundry detergent. A first water channel 611 is disposed inside the top cover 61. An inlet and a first outlet are both disposed on the top cover 61 and are respectively connected to the two ends of the first water channel 611. The inlet is connected to a water source (e.g., a faucet) through a water pipe. The first outlet is connected to the outer cylinder 2 through a water pipe. A pump body is also disposed inside the water box 63. The pump body is used to pump the laundry detergent in the chamber into the first water channel 611. The laundry detergent is mixed with the water in the first water channel 611 and then injected into the inner cylinder.

[0264] Of course, those skilled in the art can also set a mixing chamber in the water box 63, set the first water outlet on the water box 63 and connect it to the mixing chamber, and the first water channel 611 is also connected to the mixing chamber. The laundry detergent in the chamber can be pumped into the mixing chamber to mix with water by the pump body, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0265] Preferably, as shown in Figures 13 and 14, the dispensing device 6 of the present invention further includes a second water channel 612 and a second water outlet. The second water channel 612 is connected to the water inlet and the second water outlet of the dispensing device 6, and the second water outlet is connected to the water spraying device.

[0266] In other words, the dispensing device 6 is equipped with two water channels, namely the first water channel 611 and the second water channel 612. The first water channel 611 is used for the washing program, and the second water channel 612 is used for the drying program, which helps to simplify the piping and facilitates the layout.

[0267] The second waterway 612 is located on the upper surface of the cover 61 of the dispensing device 6. The cover 61 is provided with a cover plate 62, which closes the top opening of the second waterway 612. The second water outlet is located on the cover plate 62.

[0268] That is, the first waterway 611 and the second waterway 612 are both located on the upper cover 61 of the dispensing device 6. The first waterway 611 is located below the second waterway 612. The second waterway 612 is preferably connected to the water inlet of the dispensing device 6 through the first waterway 611.

[0269] For example, a water passage hole 613 is provided on the upper cover 61 to connect the first water channel 611 and the second water channel 612. Water in the first water channel 611 can enter the second water channel 612 through the water passage hole 613. A second connector pipe 621 and a third connector pipe 622 are provided on the cover plate 62. One end of the second connector pipe 621 is connected to the second water channel 612, and the other end of the second connector pipe 621 is connected to the first water spray component 51 through a water supply pipe. One end of the third connector pipe 622 is connected to the second water channel 612, and the other end of the third connector pipe 622 is connected to the first connector pipe on the second air duct 312 through a water supply pipe, thereby connecting to the second water spray component 52.

[0270] Of course, those skilled in the art may also simply provide a connector pipe on the cover plate 62 and install a three-way pipe (or three-way valve) on the connector pipe, with the two outlets of the three-way pipe connected to the first water spray component 51 and the second water spray component 52 respectively through a water supply pipe, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0271] Based on any of the washer-dryer combos described above, the present invention also provides a control method for the washer-dryer combo. The control method of the present invention includes the following steps: during the process of spraying water toward the evaporator through the water spray component, the speed of the fan is controlled not to exceed a preset speed.

[0272] The water spraying component is the second water spraying component 52 described above. During the process of spraying water toward the evaporator through the water spraying component, by controlling the speed of the fan to not exceed the preset speed, the water sprayed from the water spraying component can be prevented from being sucked into the fan.

[0273] It should be noted that during the drying process, the water spraying component can spray water towards the evaporator once every certain period of time. Alternatively, the timing of spraying water towards the evaporator can be determined based on the temperature of the evaporator. Or, the timing of spraying water towards the evaporator can be determined based on other parameters such as the power of the fan. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should all be limited to the protection scope of this invention.

[0274] Furthermore, it should be noted that, in practical applications, those skilled in the art can set a preset spraying time for the water spraying component. When the spraying time of the water spraying component reaches the preset spraying time, the water spraying component will stop spraying water. Alternatively, the temperature of the evaporator can be used to determine when to stop spraying water. Or, other parameters such as the power of the fan can be used to determine when to stop spraying water. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0275] The control method of the present invention will be described in detail below with reference to three specific examples.

[0276] Example 1

[0277] The control method for this example will be described below with reference to Figure 16.

[0278] As shown in Figure 16, the control method of this embodiment includes the following steps during the drying process:

[0279] S1: Obtain the temperature of the evaporator.

[0280] For example, a temperature sensor is provided on the evaporator, and the temperature sensor is communicatively connected to the controller of the washer-dryer to transmit the detected temperature data to the controller.

[0281] S2: Determine if the evaporator temperature is higher than the preset temperature.

[0282] After obtaining the temperature of the evaporator, the water spraying component is selectively directed to spray water toward the evaporator based on the temperature of the evaporator. Specifically, the temperature of the evaporator is compared with a preset temperature. If the temperature of the evaporator is greater than the preset temperature, step S3 is executed to direct the water spraying component to spray water toward the evaporator.

[0283] It should be noted that this invention does not limit the specific value of the preset temperature. Those skilled in the art can flexibly set the specific value of the preset temperature based on experiments or experience. For example, the preset temperature can be set to any value between 35°C and 45°C.

[0284] In addition, it should be noted that when the temperature of the evaporator is determined to be no greater than the preset temperature, the spray component can be set not to spray water toward the evaporator. Alternatively, other parameters can be used to further determine whether the spray component needs to spray water toward the evaporator. For example, it can be determined whether the running time of the drying program has reached the set time. If the running time of the drying program has reached the set time, the spray component can be made to spray water toward the evaporator, and so on.

[0285] S3: Direct the water spray component toward the evaporator.

[0286] When the temperature of the evaporator is higher than the preset temperature, it means that the temperature of the evaporator is relatively high. In this case, the water spray component needs to spray water onto the evaporator to reduce the temperature of the evaporator. Of course, while reducing the temperature of the evaporator, it can also wash off the lint attached to the evaporator.

[0287] It should be noted that, in practical applications, those skilled in the art can set a fixed preset spraying time (e.g., any value between 10 and 60 seconds) for the water spraying component. When the spraying time of the water spraying component reaches the preset spraying time, the water spraying component stops spraying water. Alternatively, while the water spraying component is spraying water toward the evaporator, the temperature of the evaporator can continue to be acquired. When the temperature of the evaporator drops to the target temperature, the water spraying component stops spraying water. The target temperature is less than the aforementioned preset temperature, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0288] S4: Control the fan speed to not exceed the preset speed.

[0289] For example, the preset speed is set to 2000 rpm. When it is determined that the water spraying component needs to spray water onto the evaporator, the speed of the fan is reduced to 2000 rpm. After the water spraying component stops spraying water, the speed of the fan is increased back to the previous operating speed.

[0290] It should be noted that the preset speed is not limited to the aforementioned 2000 rpm. Those skilled in the art can flexibly set the specific value of the preset speed based on experiments or experience in practical applications.

[0291] Example 2

[0292] The control method for this example will be described below with reference to Figure 17.

[0293] As shown in Figure 17, the control method of this embodiment includes the following steps during the execution of the drying mode:

[0294] S10: Obtain the power of the fan.

[0295] During the drying process, lint will enter the drying duct and adhere to the evaporator. When there is a lot of lint on the evaporator, it will increase the airflow resistance in the drying duct, which will reduce the power of the fan. Therefore, the power of the fan can be used to determine whether the lint on the evaporator needs to be rinsed.

[0296] S20: Determine whether the power of the fan is less than the preset power.

[0297] After obtaining the power of the fan, the water spraying component is selectively directed to spray water toward the evaporator based on the power of the fan. Specifically, the power of the fan is compared with the preset power. If the power of the fan is less than the preset power, step S3 is executed to direct the water spraying component to spray water toward the evaporator.

[0298] It should be noted that the preset power is not a fixed value, but is determined by the theoretical power of the fan at the current speed. For example, the preset power can be set to 90% to 95% of the theoretical power at the current speed.

[0299] In addition, it should be noted that when it is determined that the power of the fan is not less than the preset power, it can be set not to spray water towards the evaporator. Alternatively, other parameters can be used to further determine whether it is necessary to spray water towards the evaporator. For example, it can be determined whether the running time of the drying program has reached the set time. If the running time of the drying program has reached the set time, the spraying component can be made to spray water towards the evaporator, and so on.

[0300] S30: Direct the water spray component toward the evaporator.

[0301] When the fan power is less than the preset power, it indicates that the fan power is relatively low, which further indicates that there is a lot of lint on the evaporator. In this case, the water spray component needs to spray water onto the evaporator to wash off the lint adhering to the evaporator. Of course, while washing off the lint on the evaporator, the temperature of the evaporator can also be reduced.

[0302] It should be noted that, in practical applications, those skilled in the art can set a fixed preset spraying time (e.g., any value between 10 and 60 seconds) for the water spraying component. When the spraying time of the water spraying component reaches the preset spraying time, the water spraying component stops spraying water. Alternatively, while the water spraying component is spraying water toward the evaporator, the power of the fan can continue to be acquired. When the power of the fan rises to the target power, the water spraying component stops spraying water. The target power is greater than the preset power mentioned above. The target power can also be determined based on the theoretical power of the fan at the current speed, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0303] S40: Controls the fan speed to not exceed the preset speed.

[0304] For example, the preset speed is set to 2000 rpm. When it is determined that the water spraying component needs to spray water onto the evaporator, the speed of the fan is reduced to 2000 rpm. After the water spraying component stops spraying water, the speed of the fan is increased back to the previous operating speed.

[0305] It should be noted that the preset speed is not limited to the aforementioned 2000 rpm. Those skilled in the art can flexibly set the specific value of the preset speed based on experiments or experience in practical applications.

[0306] Example 3

[0307] Example 3 is a combination of Example 1 and Example 2 above. With other settings unchanged, this embodiment selectively sprays water towards the evaporator based on the temperature of the evaporator and the power of the fan. Specifically, the temperature of the evaporator is compared with a preset temperature; the power of the fan is compared with a preset power; if the temperature of the evaporator is greater than the preset temperature or the power of the fan is less than the preset power, then the spraying component sprays water towards the evaporator.

[0308] In other words, this embodiment sets two water spraying conditions, and as long as one of the conditions is met, the water spraying component will spray water toward the evaporator.

[0309] In addition, it should be noted that the above control methods are all executed by the controller of the washer-dryer combo.

[0310] Based on any of the washer-dryer combos described above, the present invention also provides another control method for washer-dryer combos, as shown in Figure 18. The control method of the present invention includes the following steps:

[0311] S1: Determine whether the preset opening conditions are met;

[0312] S2: If the judgment result is "yes", then turn on the cooling fan.

[0313] In other words, the cooling fan is not turned on at the beginning of the drying program. It is only turned on to cool the compressor when the preset start conditions are met. This setting can avoid affecting the drying efficiency due to the compressor heating up too slowly and is more energy-efficient.

[0314] It should be noted that the present invention does not limit the specific content of the preset activation conditions, nor does it limit the number of preset activation conditions.

[0315] The control method of the present invention will be described in detail below with reference to a specific embodiment.

[0316] As shown in Figure 19, the control method of the present invention includes the following steps:

[0317] S10: Obtain the compressor's discharge temperature.

[0318] For example, a temperature sensor can be installed at the compressor's exhaust port and connected to the washer-dryer's controller to transmit the acquired temperature data to the controller in a timely manner.

[0319] S20: Determine whether the exhaust temperature is greater than the first preset temperature.

[0320] After obtaining the compressor's exhaust temperature, the exhaust temperature is compared with a first preset temperature. If the compressor's exhaust temperature is greater than the first preset temperature, step S30 is executed to turn on the cooling fan.

[0321] It should be noted that the present invention does not limit the specific value of the first preset temperature. Those skilled in the art can flexibly set the specific value of the first preset temperature based on experiments or experience, as long as the critical point determined by the first preset temperature can prevent the compressor from overheating. The present invention preferably sets the first preset temperature to any value between 90°C and 100°C, and more preferably to 95°C.

[0322] In addition, it should be noted that, in practical applications, those skilled in the art can also set step S20 to determine whether the duration of the exhaust temperature being greater than the first preset temperature is greater than the first preset time. That is, not only does the exhaust temperature need to be greater than the first preset temperature, but the duration of the exhaust temperature being greater than the first preset temperature also needs to exceed the first preset time before the cooling fan can be turned on, which can avoid misjudgment.

[0323] Furthermore, it should be noted that the present invention does not limit the specific value of the first preset time; for example, it can be set to any value between 3s and 10s.

[0324] S30: Turn on the cooling fan.

[0325] When the compressor's exhaust temperature is higher than the first preset temperature, it indicates that the compressor's temperature is relatively high. Turn on the cooling fan to cool down the compressor and prevent it from overheating.

[0326] It should be noted that, in practical applications, those skilled in the art can set a fixed preset running time for the cooling fan, and turn it off when the cooling fan reaches the preset running time. Alternatively, they can determine when to turn off the cooling fan based on the exhaust temperature of the compressor, or they can determine when to turn off the cooling fan based on other parameters, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0327] Preferably, as shown in FIG19, the control method of the present invention further includes the following steps:

[0328] S40: Determine whether the exhaust temperature is lower than the second preset temperature.

[0329] The second preset temperature is lower than the first preset temperature.

[0330] In other words, after the cooling fan is turned on, the compressor's exhaust temperature is monitored and compared with the second preset temperature. When the compressor's exhaust temperature is lower than the second preset temperature, step S50 is executed to turn off the cooling fan.

[0331] It should be noted that the present invention does not limit the specific value of the second preset temperature. For example, the second preset temperature can be set to any value between 80°C and 85°C.

[0332] S50: Turn off the cooling fan.

[0333] After the cooling fan is turned on, the compressor's exhaust temperature drops. When the exhaust temperature is lower than the second preset temperature, it means that the compressor's temperature has returned to normal. At this point, turning off the cooling fan can prevent the compressor's exhaust temperature from dropping further and also prevent energy waste.

[0334] It should be noted that, in practical applications, those skilled in the art can make the cooling fan run at a fixed speed, or they can set multiple different speeds for the cooling fan and then control the speed of the cooling fan according to parameters such as the exhaust temperature of the compressor or the ambient temperature, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0335] In a first preferred embodiment, the cooling fan has a first speed and a second speed, the first speed being less than the second speed. The step of "turning on the cooling fan" specifically includes: running the cooling fan at the first speed. The control method of the present invention further includes:

[0336] Determine whether the decrease in exhaust temperature is greater than the preset value;

[0337] If the judgment result is "no", the speed of the cooling fan will be increased to the second speed.

[0338] In other words, when the cooling fan is first turned on, it should run at a low speed, and the rate of decrease in the compressor's exhaust temperature should be monitored. For example, the preset value is 0.5℃, and the measurement should be performed every 30 seconds. If the absolute value of the difference between the current exhaust temperature and the previous exhaust temperature is not greater than 0.5℃, it means that the cooling fan speed is too low and the cooling effect on the compressor is poor, so the cooling fan speed needs to be increased. Conversely, if the absolute value of the difference between the current exhaust temperature and the previous exhaust temperature is greater than 0.5℃, it means that the cooling fan speed meets the requirements, and the current speed can be maintained.

[0339] It should be noted that the preset value is not limited to 0.5℃ as mentioned above. For example, it can also be set to 0.1℃, 0.3℃, 0.8℃ or 1.0℃, etc. The interval time is not limited to 30s as mentioned above. For example, it can also be set to 10s, 20s, 45s or 60s, etc.

[0340] In a second preferred embodiment, the control method of the present invention further includes:

[0341] Obtain the ambient temperature near the cooling fan;

[0342] The speed of the cooling fan is determined based on the ambient temperature;

[0343] The speed of the cooling fan is positively correlated with the ambient temperature.

[0344] In other words, determining the cooling fan speed based on the ambient temperature allows for more effective cooling of the compressor.

[0345] For example, the cooling fan has three speeds: high, medium, and low, and three temperature ranges are set for the ambient temperature, which are the first temperature range, the second temperature range, and the third temperature range in order from low to high. If the ambient temperature is in the first temperature range, the cooling fan runs at a low speed; if the ambient temperature is in the second temperature range, the cooling fan runs at a medium speed; and if the ambient temperature is in the third temperature range, the cooling fan runs at a high speed.

[0346] A temperature sensor can be installed on the back panel of the cabinet and connected to the controller of the washer-dryer combo to transmit the detected temperature value to the controller in a timely manner, so that the controller can control the speed of the cooling fan.

[0347] The preferred embodiment described above determines when to turn on the cooling fan based on the compressor's exhaust temperature. In another preferred embodiment, the determination can also be based on the running time of the drying program. Specifically, the step of "determining whether the preset start-up conditions are met" includes determining whether the running time of the drying program has reached a second preset time.

[0348] When the drying program starts running, the compressor temperature will not be too high. As the drying program runs, the compressor temperature will gradually rise. When the drying program reaches the second preset time, the compressor temperature should be relatively high. At this time, the cooling fan will be turned on to cool the compressor.

[0349] It should be noted that the present invention does not limit the specific value of the second preset time. Those skilled in the art can flexibly set the specific value of the second preset time based on experiments or experience in practical applications.

[0350] In addition, it should be noted that the above control methods are all executed by the controller of the washer-dryer combo.

[0351] Example 2

[0352] Specifically, the present invention provides a washer-dryer combo machine, as shown in FIG20. The washer-dryer combo machine of the present invention includes a housing 1 and a clothes handling drum (also referred to as a drying drum) and a drying device installed in the housing 1. The drying device can deliver hot air into the clothes handling drum to dry the clothes in the clothes handling drum.

[0353] The garment handling drum includes an outer drum 2 and an inner drum that is rotatably installed in the outer drum 2. The drying device is directly connected to the outer drum 2. The inner drum is used to hold the garments. The inner drum wall is provided with multiple through holes. When the drying mode is executed, the through holes can be used for ventilation. When the washing mode is executed, the through holes can be used for water flow.

[0354] Preferably, as shown in Figures 20 to 28, the drying device of the present invention includes a drying duct 31, a fan 32, and a heat pump module. The air inlet 3111 of the drying duct 31 is connected to one end of the clothes processing drum, the air outlet 3121 of the drying duct 31 is connected to the air intake of the fan 32, and the air exhaust port of the fan 32 is connected to the other end of the clothes processing drum. The evaporator 33 and the condenser of the heat pump module are installed in the drying duct 31, and the evaporator 33 is located upstream of the condenser.

[0355] The heat pump module also includes a compressor, refrigerant piping connecting the evaporator 33 and the condenser to the compressor, and a throttling element installed on the refrigerant piping. The compressor is located outside the drying duct 31.

[0356] For example, the drying air duct 31 is located above the outer cylinder 2. An air outlet 21 is provided on the cylinder wall of the outer cylinder 2. The air outlet 21 is close to the rear end of the outer cylinder 2. A window gasket 22 is installed at the opening of the outer cylinder 2. A return air inlet 23 is provided on the window gasket 22. The air inlet 3111 of the drying air duct 31 is connected to the air outlet 21 through a corrugated pipe 34. The exhaust port of the fan 32 is connected to the return air inlet 23 through a rubber tube 35. The size of the rubber tube 35 gradually increases along the direction of airflow, which helps to reduce the resistance to airflow. The air outlet 21 and the return air inlet 23 are diagonally arranged and are both close to the top of the outer cylinder 2, roughly in the same horizontal plane. The airflow path is short, which helps to increase the number of airflow cycles, thereby improving the drying efficiency.

[0357] When the drying mode is executed, the fan 32 is started, and the humid air in the clothes processing drum is discharged through the air outlet 21 and enters the drying air duct 31. After being condensed and dehumidified by the evaporator 33, it is heated by the condenser and then flows back to the clothes processing drum from the return air outlet 23 to complete one cycle.

[0358] It should be noted that the present invention is not limited to placing the drying air duct 31 above the clothes processing drum. For example, the drying air duct 31 can also be placed below or behind the outer drum 2. Such adjustments and changes to the specific installation position of the drying air duct 31 do not deviate from the principle and scope of the present invention. Of course, the present invention preferably places the drying air duct 31 above the clothes processing drum, which is beneficial to make full use of the space above the clothes processing drum and optimize the layout.

[0359] Furthermore, it should be noted that those skilled in the art can also interchange the positions of the air outlet 21 and the return air outlet 23, such as air outlet at the front end and air inlet at the rear end of the clothing treatment drum. Alternatively, the air outlet 21 can be located on the rear wall of the outer drum 2, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0360] Furthermore, it should be noted that those skilled in the art can also connect the air intake of the fan 32 to the air outlet 21 on the clothes processing drum, and then connect the exhaust port of the fan 32 to the air inlet 3111 of the drying duct 31. Alternatively, the drying duct 31 can be set into two sections, with the fan 32 installed between the two sections. Or, the fan 32 can be directly installed inside the drying duct 31, etc. Such adjustments and changes to the installation position of the fan 32 do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0361] Furthermore, it should be noted that those skilled in the art can also omit the heat pump module in practical applications and use other types of dehumidifying and heating components to dehumidify and heat the airflow in the drying duct 31. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0362] Preferably, as shown in Figures 20 to 26, the washer-dryer of the present invention further includes a lint filter 4 installed in the housing 1. The lint filter 4 is installed in the drying air duct 31 and is located upstream of the evaporator 33.

[0363] The lint filter 4 is used to filter the airflow entering the drying duct 31. When the airflow in the drying duct 31 flows through the lint filter 4, the lint and other impurities carried by the airflow are intercepted by the lint filter 4, and the filtered lint is stored in the lint filter 4.

[0364] Preferably, as shown in Figures 20 to 26, the lint filter 4 of the present invention is detachably installed in the drying air duct 31, and the drying air duct 31 is provided with an insertion interface 3112, through which the lint filter 4 is inserted into the drying air duct 31.

[0365] When it is necessary to clean the lint inside the lint filter 4, the lint filter 4 can be removed from the drying air duct 31. A pressure sensor can be installed upstream and downstream of the lint filter 4. The pressure difference between the two sensors determines whether the lint filter 4 needs cleaning. When cleaning is required, a prompt message can be sent to the user to remind them to clean the lint filter 4.

[0366] It should be noted that, in practical applications, those skilled in the art can place the connector 3112 on the side of the drying duct 31, or on the top surface of the drying duct 31, etc. Such adjustments and changes to the specific location of the connector 3112 do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0367] Preferably, as shown in Figure 20, the drying air duct 31 is provided with an insertion interface 3112 on the side facing the front panel of the housing 1, and the front panel is provided with a disassembly port at the position opposite to the insertion interface 3112, so that the lint filter device 4 can be pulled out from the disassembly port.

[0368] When it is necessary to clean the lint filter device 4, the user can pull out the lint filter device 4 from the disassembly port on the front panel of the housing 1 for easy operation. After cleaning the lint filter device 4, the user can then insert the lint filter device 4 back in through the disassembly port.

[0369] Preferably, as shown in Figures 20 to 28, the drying duct 31 of the present invention includes a first duct 311 and a second duct 312 that are connected to each other. The first duct 311 extends in the front-to-back direction, and the second duct 312 extends in the left-to-right direction and is close to the front end of the clothes processing drum. The air inlet 3111 of the drying duct 31 is located in the first duct 311, and the air outlet 3121 of the drying duct 31 is located in the second duct 312. The lint filter 4 is installed in the first duct 311, and the evaporator 33 and the condenser of the drying module are installed in the second duct 312.

[0370] For example, both the first air duct 311 and the second air duct 312 are located above the outer cylinder 2. The first air duct 311 is located at the upper left of the outer cylinder 2 and extends from the rear end to the front end of the outer cylinder 2. An air inlet port 3111 is provided on the bottom wall of the rear end of the first air duct 311. An air outlet 21 on the outer cylinder 2 is located directly below the air inlet port 3111. The air outlet 21 is connected to the upper air inlet port 3111 through a corrugated pipe 34. An insertion interface 3112 is provided at the front end of the first air duct 311. The lint filter 4 is inserted into the first air duct 311 through the front end of the first air duct 311. Inside the duct 311, the left end of the second air duct 312 is connected to the first air duct 311, and the right end of the second air duct 312 is provided with an air outlet port 3121. The evaporator 33 is arranged on the left side of the condenser. The size of the second air duct 312 gradually decreases near the air outlet port 3121, which is conducive to the airflow fully exchanging heat with the evaporator 33 and the condenser. The fan 32 is located on the upper right side of the outer cylinder 2. The fan 32 is vertically arranged on the right side of the second air duct 312. The air intake of the fan 32 is connected to the air outlet port 3121 on the second air duct 312. The air intake of the fan 32 is located on the left side of the fan 32.

[0371] It should be noted that, in practical applications, those skilled in the art may also place the first air duct 311 in the upper right of the garment processing drum, and correspondingly place the fan 32 in the upper left of the garment processing drum. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0372] Of course, the present invention preferably places the first air duct 311 in the upper left corner of the outer cylinder 2. A detergent dispensing device is generally provided in the upper left corner. The present invention preferably places the first air duct 311 directly above the detergent dispensing device.

[0373] Preferably, as shown in Figures 22, 26 and 27, the washer-dryer of the present invention includes an air inlet pipe 51 and an air outlet pipe 52. A fresh air inlet 3114 is provided on the drying air duct 31. The fresh air inlet 3114 is located upstream of the lint filter device 4 and is connected to one end of the air inlet pipe 51. A fresh air outlet is provided on the outer cylinder 2. The fresh air outlet is connected to one end of the air outlet pipe 52. The other end of the air outlet pipe 52 is connected to the drain pipe 7 of the washer-dryer and is discharged through the drain pipe 7.

[0374] Among them, the drain pipe 7 is connected to the outer cylinder 2. The drain pipe 7 refers to the pipe used to discharge water from the outer cylinder 2. It generally also includes a drain pump. The inlet end of the drain pump is connected to the outer cylinder 2, the outlet end of the drain pump is connected to one end of the drain pipe 7, and the other end of the drain pipe 7 is connected to the floor drain.

[0375] During the drying process, fresh air from outside can be drawn into the drying duct 31 through the air inlet pipe 51, and then enter the inner and outer cylinders 2 along the drying duct 31. Some of the humid air in the inner cylinder can be discharged into the drain pipe 7 through the exhaust pipe 52, and then directly discharged to the floor drain through the drain pipe 7. By introducing fresh air, the drying efficiency can be improved.

[0376] Preferably, as shown in Figures 20 to 23, 26 and 27, the fresh air inlet 3114 is located upstream of the lint filter device 4.

[0377] For example, the fresh air inlet 3114 is located in the first air duct 311, preferably at the rear end of the first air duct 311. An air inlet is provided on the back plate of the housing 1. The other end of the air inlet pipe 51 is connected to the air inlet on the back plate. The fresh air outlet is located on the rear wall of the outer cylinder 2. The exhaust pipe 52 is located behind the outer cylinder 2.

[0378] It should be noted that, in practical applications, those skilled in the art may also position the fresh air inlet downstream of the online dust filter 4, for example, between the online dust filter 4 and the evaporator 33.

[0379] Furthermore, it should be noted that, in practical applications, those skilled in the art can also place the air inlet on the top or side plate of the housing 1, or alternatively, omit the air inlet from the housing 1 and position the other end of the air inlet pipe 51 between the clothing processing drum and the housing 1, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention. Of course, the present invention preferably places the air inlet on the back plate of the housing 1.

[0380] Furthermore, it should be noted that the fresh air outlet is not limited to being located on the rear wall of the outer cylinder 2. For example, it can also be located on the top or side of the outer cylinder 2. Such adjustments and changes to the specific location of the fresh air outlet do not deviate from the principles and scope of this invention and should all be limited to the protection scope of this invention. Of course, this invention preferably places the fresh air outlet on the rear wall of the outer cylinder 2 and near the top of the outer cylinder 2.

[0381] Preferably, as shown in FIG22, the washer-dryer of the present invention further includes an electric valve 53 installed on the air inlet pipe 51, the electric valve 53 being used to control the opening and closing of the air inlet pipe 51.

[0382] The electric valve 53 is connected to the controller of the washer-dryer combo. During the drying mode, if fresh air is introduced, the electric valve 53 will be opened; if fresh air is not introduced, the electric valve 53 will remain closed.

[0383] Preferably, as shown in FIG22, the washer-dryer of the present invention is also provided with a one-way valve 54 on the exhaust pipe 52.

[0384] By installing a one-way valve 54 on the exhaust pipe 52, it is possible to prevent odors or sewage from the floor drain from flowing back into the outer cylinder 2 along the exhaust pipe 52.

[0385] Preferably, as shown in Figures 22, 26 and 28, the washer-dryer of the present invention further includes a condensate pipe 6, and the drying air duct 31 is provided with a drain outlet 3123 at a position corresponding to the evaporator 33. The drain outlet 3123 is connected to the drain pump (not shown in the figure) of the washer-dryer through the condensate pipe 6.

[0386] The drain pump refers to the water pump used to drain the water from the outer cylinder 2.

[0387] For example, the drain outlet 3123 is located on the bottom wall of the second air duct 312. When the humid air flows through the evaporator 33, the moisture carried by the humid air condenses into condensate on the surface of the evaporator 33. The condensate drips onto the bottom wall of the second air duct 312 and enters the condensate pipe 6 along the drain outlet 3123. The drain pump is located at the lower right corner of the outer cylinder 2. The bottom end of the condensate pipe 6 is connected to the inlet end of the drain pump through a three-way valve. The outlet end of the drain pump is connected to the drain pipe 7. The condensate enters the drain pump along the condensate pipe 6. After the drain pump is started, it discharges the condensate into the drain pipe 7. The drain pipe 7 is connected to the floor drain, and the condensate is discharged directly into the floor drain. The condensate does not enter the outer cylinder 2.

[0388] It should be noted that, in practical applications, those skilled in the art can also connect the drain outlet 3123 on the second air duct 312 directly to the drain pipe 7 via the condensate pipe 6, so that the condensate can be discharged directly into the floor drain via the drain pipe 7. In this way, there is no need to start the drain pump.

[0389] Preferably, as shown in Figures 24 and 25, the drying duct 31 of the present invention is provided with an inspection port 3122 at a position corresponding to the evaporator 33 and the condenser, and the drying device further includes an upper cover 313 for closing the inspection port 3122.

[0390] For example, the access port 3122 is provided on the second air duct 312 and located at the top of the second air duct 312. The evaporator 33 and the condenser are located below the access port 3122. When the evaporator 33 or the condenser needs to be repaired, the top cover 313 is opened to expose the evaporator 33 and the condenser for easy repair. After the repair is completed, the access port 3122 is closed again through the top cover 313.

[0391] It should be noted that the inspection port 3122 is not limited to being located at the top of the drying duct 31. For example, it can also be located on the side of the drying duct 31. Such adjustments and changes to the specific location of the inspection port 3122 do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention. Of course, the present invention preferably places the inspection port 3122 at the top of the drying duct 31.

[0392] Furthermore, it should be noted that, in practical applications, those skilled in the art may pivotally connect the upper cover 313 to the drying duct 31, or use fasteners such as screws to fix the upper cover 313 to the drying duct 31, etc. Such adjustments and changes to the specific connection method between the upper cover 313 and the drying duct 31 do not deviate from the principles and scope of the present invention, and should all be limited to the protection scope of the present invention.

[0393] Preferably, the top plate of the housing 1 has an opening at a position corresponding to the inspection port 3122, and the housing 1 also includes a top cover to close the opening.

[0394] By setting an opening on the top plate of the housing 1, when the evaporator 33 or condenser needs to be repaired, it is not necessary to remove the entire top plate. Simply open the top cover and then open the top cover 313 on the drying air duct 31 through the opening on the top plate, making the operation more convenient.

[0395] The opening on the top plate is larger than the inspection port 3122 on the drying air duct 31, making it easier to carry out maintenance work.

[0396] Preferably, as shown in Figures 24 to 26, the washer-dryer of the present invention further includes a first rinsing device, which is located at the corner of the drying air duct 31 near the air inlet port 3111. The first rinsing device is used to rinse the inner wall of the drying air duct 31 at the corner.

[0397] After the airflow in the garment processing drum is discharged from the air outlet 21, it first flows upward and then turns to flow horizontally after impacting the top wall of the drying air duct 31. The corner refers to the position where the airflow changes from vertical to horizontal. Lint is prone to accumulate at the corner of the drying air duct 31. By setting up a first rinsing device to rinse the inner wall of the drying air duct 31 at the corner, the lint at the corner is washed away, which helps to ensure smooth airflow and thus improves drying efficiency.

[0398] For example, the first flushing device is connected to the first air duct 311 and is used to flush the inner wall of the first air duct 311 at the corner.

[0399] It should be noted that the present invention does not limit the specific structural form of the first rinsing device. For example, those skilled in the art can set the first rinsing device as a water spray pipe, or set the first rinsing device as a water spray channel formed on the drying air duct, etc. Such adjustments and changes to the specific structural form of the first rinsing device do not deviate from the principle and scope of the present invention, and should all be limited to the protection scope of the present invention.

[0400] Preferably, as shown in Figures 24 to 26, the first rinsing device includes a water spray pipe 8, which is inserted into the drying air duct 31. The water spray pipe 8 is provided with a water spray nozzle, which faces the inner wall of the drying air duct 31.

[0401] For example, a portion of the water spray pipe 8 is inserted into the first air duct 311. The portion of the water spray pipe 8 inserted into the first air duct 311 is located above the air inlet port 3111. The air inlet port 3111 is located on the bottom wall of the first air duct 311. The end of the water spray pipe 8 located outside the first air duct 311 is connected to a water source (such as a faucet) through a water supply pipe. A solenoid valve is installed on the water supply pipe. When it is necessary to rinse the inner wall of the first air duct 311 at the corner, the solenoid valve is opened to supply water to the water spray pipe 8. Water is sprayed onto the inner wall of the first air duct 311 through the spray nozzle. Water and lint flow into the outer cylinder 2 from the air inlet port 3111 of the first air duct 311 and are finally discharged through the drain pipe 7.

[0402] Preferably, as shown in Figures 24 to 26, the washer-dryer of the present invention further includes a second rinsing device 9 installed in the second air duct 312, the second rinsing device 9 being used to rinse the evaporator 33.

[0403] Wire debris can easily accumulate on the evaporator 33. By setting up a second flushing device 9 to flush the evaporator 33, it is beneficial to ensure the heat exchange efficiency between the airflow and the evaporator 33, thereby improving the efficiency of condensation and dehumidification, and thus improving the drying efficiency.

[0404] For example, the second flushing device 9 includes a strip-shaped housing located above the evaporator 33 and extending in the front-to-back direction. The bottom wall of the housing is provided with multiple water spray holes, and the top of the housing is open. The top of the housing is sealed to the inner top wall of the second air duct 312. The second air duct 312 is provided with a water inlet at a position corresponding to the housing. A water pipe connector 91 is installed on the water inlet. The water pipe connector 91 is connected to a water source (such as a faucet) through a water supply pipe. A solenoid valve is provided on the water supply pipe. When it is necessary to flush the evaporator 33, the solenoid valve is opened to supply water to the second flushing device 9. Water is sprayed onto the evaporator 33 through the multiple water spray holes on the second flushing device 9. Water and lint flow into the condensate pipe 6 through the drain outlet 3123 of the second air duct 312, then into the drain pipe 7 through the condensate pipe 6, and finally discharged through the drain pipe 7.

[0405] It should be noted that the second flushing device 9 is not limited to the structure of the housing described above. For example, the second flushing device 9 can also be configured as a flushing water pipe or a flushing channel formed on the second air duct 312, etc. Such adjustments and changes to the specific structural form of the second flushing device 9 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0406] Preferably, as shown in Figures 28 to 30, the lint filtering device 4 of the present invention includes a housing 41 and a first filter screen installed on the housing 41. The first side of the housing 41 is provided with an air inlet 411, and the second side of the housing 41 is provided with an air outlet 412. One of the first side and the second side is a side in the length direction of the housing 41, and the other of the first side and the second side is a side in the width direction of the housing 41. The first filter screen is installed at the air outlet 412.

[0407] For example, the housing 41 of the lint filter device 4 is a rectangular housing 41 that extends in the front-to-back direction. The first side is the rear end face of the housing 41 (i.e., the side of the housing 41 in the length direction), and the second side is the right side face of the housing 41 (i.e., the side of the housing 41 in the width direction). The second side faces the second air duct 312. The airflow entering the first air duct 311 first enters the housing 41 through the air inlet 411 at the rear end of the housing 41, and then exits through the air outlet 412 on the right side of the housing 41 and enters the second air duct 312. After being dehumidified by the evaporator 33 and heated by the condenser in the second air duct 312, it is discharged from the air outlet 3121 at the right end of the second air duct 312 and enters the fan 32. Finally, it is blown into the clothes processing drum by the fan 32.

[0408] Preferably, the lint filter device 4 of the present invention further includes a second filter screen installed inside the housing 41, the second filter screen being located between the air inlet 411 and the first filter screen.

[0409] Installing a second filter between the air inlet 411 and the first filter screen improves the filtration effect of the lint filter device 4.

[0410] It should be noted that, in practical applications, those skilled in the art can make the mesh count of the first filter screen greater than that of the second filter screen, or they can make the mesh count of the first filter screen equal to that of the second filter screen.

[0411] Ideally, the mesh size of the first filter screen should be larger than that of the second filter screen. That is, the filter first undergoes coarse filtration through the second filter screen, and then undergoes fine filtration through the first filter screen.

[0412] Preferably, the second filter screen is arc-shaped and protrudes towards the first filter screen.

[0413] In other words, the center of the second filter is located on the side of the second filter that is far away from the first filter, which helps to increase the filtration area of ​​the second filter.

[0414] It should be noted that the shape of the second filter is not limited to an arc shape. For example, it can also be straight or V-shaped, etc. Such adjustments and changes to the specific shape of the second filter do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0415] Of course, the present invention preferably sets the second filter screen to be arc-shaped, which is more conducive to increasing the filtration area of ​​the second filter screen, thereby improving the filtration effect of the lint filter device 4.

[0416] Preferably, the second filter extends from the connection between the first and second sides of the housing 41 toward the third side of the housing 41, with the third side opposite to the second side.

[0417] Preferably, the second filter screen is connected to the third side of the outer casing 41.

[0418] Preferably, as shown in Figures 29 to 31, the lint filter device 4 of the present invention further includes a mounting bracket 42 detachably installed in the housing 41, the mounting bracket 42 being able to be pulled out from the air inlet 411 of the housing 41, and the second filter screen being disposed on the mounting bracket 42.

[0419] By setting the mounting bracket 42 to be able to be pulled out from the air inlet 411 of the housing 41, it is convenient to clean the second filter. In addition, during the process of pulling out the mounting bracket 42 and the second filter, the lint filtered by the second filter will also come out with the mounting bracket 42, which can achieve the effect of scraping off lint.

[0420] Preferably, as shown in Figures 29 to 31, the mounting frame 42 of the lint filter device 4 of the present invention includes a first frame 421, a second frame 422 and a connecting plate 423. The first end of the first frame 421 is connected to the first end of the second frame 422, and the second end of the first frame 421 and the second end of the second frame 422 are connected by the connecting plate 423. The first frame 421 is located at the air inlet 411, the second filter screen is disposed on the second frame 422, and the connecting plate 423 is disposed opposite to the second side of the outer casing 41.

[0421] Preferably, the shape of the second frame 422 is the same as that of the second filter screen. If the second filter screen is set to be arc-shaped, the second frame 422 is also preferably arc-shaped. The second filter screen extends from the first end of the second frame 422 to the second end of the second frame 422.

[0422] For example, the first frame 421, the second frame 422 and the connecting plate 423 are connected end to end. All the lint filtered by the second filter is located inside the mounting bracket 42. When the mounting bracket 42 is pulled out from the housing 41, it is more convenient to scrape off all the lint filtered by the second filter, thereby improving the lint removal effect.

[0423] Preferably, as shown in Figures 29 and 31, the connecting plate 423 of the mounting bracket 42 is fitted to the inner wall of the third side of the housing 41.

[0424] In other words, the second end of the second frame 422 is connected to the third side of the outer casing 41, that is, the second filter screen is connected to the third side of the outer casing 41.

[0425] Preferably, as shown in Figures 29 to 31, the outer shell 41 of the lint filter device 4 is provided with a first snap-fit ​​structure 416, and the first frame 421 is provided with a second snap-fit ​​structure 4213, and the first snap-fit ​​structure 416 and the second snap-fit ​​structure 4213 are snap-fitted together.

[0426] For example, the first snap-fit ​​structure 416 is a snap-fit ​​opening provided on the outer shell 41, and the second snap-fit ​​structure 4213 is a snap hook provided on the first frame 421. The snap hook is adapted to the snap-fit ​​opening. The outer shell 41 is provided with a snap-fit ​​opening at the top and bottom, and correspondingly, the first frame 421 is also provided with a snap hook at the top and bottom.

[0427] It should be noted that the first snap-fit ​​structure 416 and the second snap-fit ​​structure 4213 are not limited to the structure of the snap-fit ​​and the hook as described above. For example, they can also be configured as a structure of the slot and the hook, or as a structure of two hooks. Such adjustments and changes to the specific structural forms of the first snap-fit ​​structure 416 and the second snap-fit ​​structure 4213 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0428] Preferably, the radius of the second filter screen is R, and the dimension of the second filter screen along the length direction of the outer shell 41 is L, where 1.0≤R / L≤3.0.

[0429] For example, the connecting plate 423 of the mounting bracket 42 is attached to the third side of the housing 41, and the two ends of the connecting plate 423 are respectively connected to the second end of the first frame 421 and the second end of the second frame 422. Then, as shown in Figure 31, the dimension L of the second filter screen along the length direction of the housing 41 is the length of the connecting plate 423.

[0430] By limiting R / L to between 1.0 and 3.0, the second filter can achieve a better filtration effect. For example, R / L can be set to 1.0, 1.5, 2.0, 2.5, or 3.0. More preferably, 2.0 ≤ R / L ≤ 2.5.

[0431] Preferably, as shown in Figures 29 and 30, at least a portion of the housing 41 of the lint filter device 4 of the present invention is made transparent.

[0432] By making a portion of the housing 41 transparent, it is easy to observe whether the lint inside the housing 41 has been cleaned.

[0433] Preferably, as shown in Figures 29 and 30, the housing 41 of the lint filter device 4 of the present invention is provided with a cleaning window 413, and the housing 41 further includes a cover plate 414 for closing the cleaning window 413, the cover plate 414 being transparent.

[0434] For example, the cover plate 414 is pivotally connected to the housing 41. When it is necessary to clean the wire debris inside the housing 41, the cover plate 414 can be opened and the wire debris inside the housing 41 can be cleaned through the cleaning window 413 on the housing 41.

[0435] Preferably, as shown in FIG28, a handle 43 is provided on the outer side wall of the fourth side of the housing 41 of the lint filter device 4 of the present invention, and the fourth side is opposite to the first side.

[0436] By providing a handle 43 on the outer casing 41, it is easier to pull the lint filter 4 out of the drying air duct 31.

[0437] Preferably, as shown in Figures 29, 30 and 32, the lint filter device 4 of the present invention further includes a scraping member 44, which is connected to the mounting bracket 42 and located on the side of the mounting bracket 42 away from the air inlet 411 of the outer casing 41. The scraping member 44 can scrape off the lint inside the outer casing 41 as the mounting bracket 42 is pulled out.

[0438] The mounting bracket 42 can only scrape off the lint filtered by the second filter screen. By setting the scraping component 44, the lint filtered by the first filter screen can also be scraped off during the process of pulling out the mounting bracket 42, which helps to improve the cleaning efficiency of the lint filter device 4.

[0439] For example, the scraping member 44 is connected to the connecting plate 423 of the mounting bracket 42. After connecting the first frame 421 and the second frame 422, the connecting plate 423 extends forward to connect with the scraping member 44. Of course, the connecting plate 423 may not extend forward, and the scraping member 44 may be directly connected to the connecting plate 423 at the position where the connecting plate 423 connects with the second frame 422.

[0440] It should be noted that those skilled in the art can configure the scraping component 44 as a scraping plate, scraping block, or scraping frame, etc., in practical applications. Such adjustments and changes to the specific structural form of the scraping component 44 do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0441] Preferably, as shown in Figures 29 and 32, the scraping component 44 of the present invention includes an annular scraper 441 and a sealing plate 442. The annular scraper 441 is attached to the inner wall of the housing 41 of the lint filter device 4, and the sealing plate 442 is connected to the annular scraper 441 and closes the end of the annular scraper 441 away from the air inlet 411.

[0442] For example, the outer casing 41 has a rectangular cross-section, and the annular scraper 441 also forms a rectangular ring. The four sides of the annular scraper 441 are respectively attached to the four inner walls of the outer casing 41, and the sealing plate 442 is integrally formed with the annular scraper 441. The sealing plate 442 can be regarded as the fourth side of the outer casing 41, and the handle 43 of the lint filter device 4 is provided on the outer side wall of the sealing plate 442.

[0443] Preferably, as shown in Figures 26 to 29, the lint filter device 4 of the present invention is provided with a first annular sealing member 45 at one end near the insertion interface 3112 of the drying air duct 31, and a second annular sealing member 46 at the other end. Both the first annular sealing member 45 and the second annular sealing member 46 are sealed and fitted to the inner wall of the drying air duct 31, and the outer diameter of the first annular sealing member 45 is larger than the outer diameter of the second annular sealing member 46.

[0444] In other words, the second annular sealing member 46 located at the inner end is smaller in size. This helps to reduce the friction between the lint filter device 4 and the drying air duct 31 during the installation and disassembly of the lint filter device 4, making it easier to operate.

[0445] For example, the first annular sealing member 45 is disposed at one end of the housing 41 near the insertion interface 3112 of the drying air duct 31, and the second annular sealing member 46 is disposed at the end of the mounting bracket 42 away from the insertion interface 3112. Specifically, the second annular sealing member 46 is disposed on the first frame 421, and both the first annular sealing member 45 and the second annular sealing member 46 are sealed and fitted against the inner wall of the first air duct 311. Of course, if the mounting bracket 42 is not provided, the second annular sealing member 46 can also be disposed on the housing 41 of the lint filter device 4.

[0446] It should be noted that the present invention does not limit the specific structural form of the first annular sealing member 45 and the second annular sealing member 46. For example, they can be configured as an annular sealing gasket, an annular sealing ring, or an annular structure composed of multiple sealing strips.

[0447] Preferably, as shown in Figures 29 and 30, the lint filter device 4 is provided with a first annular groove 415, and the first annular sealing member 45 is a first annular sealing ring disposed in the first annular groove 415.

[0448] For example, a first annular groove 415 is provided at one end of the housing 41 of the online chip filter device 4, and a first annular sealing ring is installed in the first annular groove 415.

[0449] Preferably, as shown in Figures 29 and 31, the lint filter device 4 is provided with a second annular groove 4211, and the second annular sealing member 46 is a second annular sealing ring disposed in the second annular groove 4211.

[0450] For example, a second annular groove 4211 is provided on the first frame 421 of the mounting bracket 42 of the wire chip filter device 4, and a second annular sealing ring is installed in the second annular groove 4211.

[0451] Preferably, as shown in Figures 26 and 27, a blocking and positioning structure 3113 is provided on the inner wall of the drying air duct 31 at a position away from the insertion interface 3112. The blocking and positioning structure 3113 abuts against the lint filter device 4 to position the lint filter device 4 in a set installation position.

[0452] For example, the blocking positioning structure 3113 is disposed on the inner wall of the first air duct 311. During the process of inserting the lint filter device 4 into the first air duct 311, when the end of the lint filter device 4 abuts against the blocking positioning structure 3113, the lint filter device 4 can no longer move forward, indicating that the lint filter device 4 is installed in place.

[0453] It should be noted that, in practical applications, those skilled in the art can configure the housing 41 of the lint filter device 4 to abut against the blocking positioning structure 3113, or the mounting bracket 42 of the lint filter device 4 to abut against the blocking positioning structure 3113, or a structure (such as a block or baffle) that cooperates with the blocking positioning structure 3113 can be provided on the housing 41 or the mounting bracket 42. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0454] Furthermore, it should be noted that those skilled in the art can configure the blocking positioning structure 3113 as a blocking positioning plate, blocking positioning rib, or blocking positioning block in practical applications. Such adjustments and changes to the specific structural form of the blocking positioning structure 3113 do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0455] Preferably, as shown in Figures 26 and 27, the blocking positioning structure 3113 is an annular positioning rib formed on the inner wall of the drying air duct 31.

[0456] For example, an annular positioning rib is provided along the inner wall of the first air duct 311. The annular positioning rib protrudes from the inner wall of the first air duct 311 into the interior of the first air duct 311. During the installation of the lint filter device 4, the housing 41 or mounting bracket 42 of the lint filter device 4 abuts against the annular positioning rib.

[0457] Preferably, as shown in Figures 26, 27 and 31, the side of the annular positioning rib facing the insertion interface 3112 of the drying air duct 31 is set as a first inclined surface 31131, and the lint filter device 4 is provided with a second inclined surface 4212, with the first inclined surface 31131 and the second inclined surface 4212 abutting and fitting together.

[0458] For example, the second inclined surface 4212 is disposed on the first frame 421 of the mounting bracket 42 of the wire lint filter device 4. During the installation of the wire lint filter device 4, the first inclined surface 31131 in the first air duct 311 abuts against the second inclined surface 4212 on the mounting bracket 42 of the wire lint filter device 4.

[0459] Preferably, as shown in FIG28, the air outlet 412 of the lint filter device 4 is higher than the air outlet 3121 of the drying air duct 31.

[0460] By positioning the air outlet 412 of the lint filter 4 higher than the air outlet 3121 on the drying duct 31, the airflow is tilted downwards, which helps to reduce the resistance to the airflow.

[0461] It should be noted that "the air outlet 412 is higher than the air outlet 3121" means that the lowest point of the air outlet 412 is higher than the lowest point of the air outlet 3121.
