[0002] In existing laundry processing devices, the interior of the drum housing the laundry is connected to the drying duct of the drying assembly. During the drying process, air circulates between the drum and the drying duct, carrying lint from the laundry into the duct. This airflow then traps lint on the impeller, reducing drying efficiency. Furthermore, the lint remaining on the impeller is carried further into the drum and deposited on other laundry items. Current solutions primarily involve adding filters to the duct to filter out lint. However, as lint accumulates on the filter, air resistance increases, impacting drying efficiency.

[0025] In the above technical solution, the liquid level detection assembly includes a liquid level probe, and the liquid level probe includes a first probe and a second probe;

[0026] The distance from the first probe to the bottom of the water storage chamber is smaller than the distance from the second probe to the bottom of the water storage chamber;

[0027] The clothes treating device is preset with a first preset water level and a second preset water level, and the first preset water level is lower than the second preset water level;

[0028] The first preset water level is the water level height when the water level in the water storage chamber reaches the bottom of the first probe;

[0059] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0060] In existing clothing processing devices, the interior of a drum for accommodating clothing is connected to a drying duct of a drying assembly. During the drying process, air circulates between the drum and the drying duct, carrying lint from clothing inside the drum into the duct. This causes lint to remain on the impeller in the duct, reducing drying efficiency. Furthermore, the lint remaining on the impeller is carried into the drum and remains on other clothing. In an embodiment of the present invention, a switchable assembly for opening and closing the drying duct is provided in the drying duct, allowing the drying duct to be used for drying clothing when opened, and forming a water storage chamber in the drying duct when closed, thereby cleaning the fan impeller and improving the drying effect on clothing.

[0061] To further illustrate the technical solution of the present invention, Figures 1-10 As shown, the following specific embodiments are provided.

[0062] Example 1

[0063] On the one hand, an embodiment of the present invention provides a Figure 1 and Figure 2 The clothes treating device shown comprises:

[0064] A clothes processing drum 1, the interior of which forms a clothes processing chamber;

[0065] The air duct housing 2 is mounted on the top of the laundry processing drum 1, and has a drying air duct formed therein that is connected to the laundry processing drum. The laundry processing drum is provided with an air inlet 11 and an air outlet 12. The air inlet end of the air duct housing is connected to the air outlet 12 of the laundry processing drum, and the air outlet end is connected to the air inlet 11 of the laundry processing drum 1;

[0066] The fan assembly 3 is installed in the air duct housing and includes a fan impeller 31 built into the drying air duct. The fan impeller 31 is used to provide power for the drying air flow in the drying air duct.

[0067] The switchable component 6 is used to open or close the drying air duct. When the clothes processing device performs a drying program, the switchable component opens the drying air duct to dry the clothes in the clothes processing chamber. When the clothes processing device performs a fan cleaning program, the switchable component closes the drying air duct so that the drying air duct forms a water storage chamber at the switchable component for accommodating cleaning water.

[0068] The impeller is configured to be located above the on / off assembly, and when the clothes treating device performs a blade cleaning procedure, the blade can be at least partially immersed in the water storage chamber;

[0069] A water injection component 4 is configured to inject cleaning water into the drying air duct when the on / off component 6 is closed;

[0070] The drainage component 5 is used to drain the washing water in the water storage chamber after the clothes processing device performs the fan blade cleaning program.

[0071] When the clothes processing device executes the drying program, the on-off component 6 can open the drying air duct. At this time, a circulating air duct is formed between the drying air duct and the clothes processing chamber of the clothes processing drum 1. The fan component 3 is turned on, and the fan component 3 drives the fan impeller 31 to rotate and drive the air to circulate in the circulating air duct to dry the clothes in the clothes processing chamber.

[0072] When the fan blade cleaning program is executed, the on-off component 6 closes the drying air duct. When the drying air duct is closed, a water storage chamber that can accommodate cleaning water is formed in the drying air duct. The water injection component 4 is opened to inject water into the formed water storage chamber through the water injection pipe. When the water level in the water storage chamber exceeds the fan impeller 31 or at least partially submerges the fan impeller 31, the fan impeller 31 is started. At this time, the fan impeller 31 rotates in the water in the water storage chamber, thereby achieving cleaning of the fan impeller 31. After the fan impeller 31 is cleaned, the drainage component 5 can drain the water in the water storage chamber, thereby completing the cleaning operation of the fan impeller 31.

[0073] It should be noted that when the drying process is executed, the fan assembly 3 is running at the same time as the heating assembly. This embodiment does not limit the specific location of the heating assembly. For example, the heating assembly can be placed in the air duct housing 2, or in the laundry processing drum 1, as long as the heating effect can be achieved. This embodiment also does not limit the specific composition of the heating assembly. For example, the heating assembly can be composed of multiple heating tubes, or multiple heating wires.

[0074] It should also be noted that when executing the drying program, the water injection component 4 can be further opened after the drying air duct is opened, so that condensed water can be injected into the clothing treatment drum 1. The advantage of injecting washing water into the clothing treatment drum 1 during the drying program is that: when the heating component converts the air into high-temperature dry gas and enters the clothing treatment drum to exchange heat with the wet clothes, the clothing treatment drum 1 is now relatively low-temperature and high-humidity air. The purpose of injecting condensed water into the clothing treatment drum is to condense the high-humidity air and convert it into low-temperature and low-humidity air, which is then heated by electric heating to become high-temperature dry air, thereby achieving a drying effect on the clothes in the clothing treatment drum 1.

[0075] In any of the above embodiments, Figure 1 As shown, the clothes processing drum is provided with an air inlet 11 and an air outlet 12, wherein the air inlet end of the air duct housing 2 is connected to the air outlet 12 of the clothes processing drum, and the air outlet end is connected to the air inlet 11 of the clothes processing drum 1;

[0076] The switchable component 6 is provided at the air inlet end of the air duct housing 2 and is used to open or close the drying air duct. When the switchable component 6 closes the drying air duct, the water storage cavity mentioned above is formed between the air duct housing 2 and the air outlet 12 of the clothing processing drum 1.

[0077] Specifically, the air duct housing 2 includes a rear air duct housing 21, a middle air duct housing 22 and a front air duct housing 23;

[0078] The rear air duct shell 21 forms an arc-shaped air duct, the fan impeller 31 is accommodated in the arc-shaped air duct, the intermediate air duct shell 22 is connected to the rear air duct shell 21 and extends along the tangential direction of the rear air duct shell 21. When the on-off component 6 closes the drying air duct, the above-mentioned water storage chamber is formed between the rear air duct shell 21 and the air outlet 12 of the clothing processing drum 1.

[0079] More specifically, the air inlet 11 and air outlet 12 of the laundry processing drum 1 are respectively arranged on the front and rear sides of the top of the laundry processing drum 1; the rear air duct housing 21, the middle air duct housing 22, and the front air duct housing 23 extend from the rear side of the top of the laundry processing drum 1 to the front side of the top of the laundry processing drum 1. The advantage of arranging the air duct housing 2 in a front-to-back direction is that when drying the clothes in the laundry processing drum 1, the drying area of ​​the clothes in the laundry processing drum 1 can be increased, and the drying effect is more significant.

[0080] In order to further understand how the switchable component 6 in this embodiment realizes the switch control of the drying air duct, the following is combined with Figure 1 、 Figure 3 and Figure 4 The switchable component 6 is further described as follows:

[0081] like Figure 3 and Figure 4 As shown, the on-off component 6 includes a flip cover 61 provided at the air inlet end of the air duct housing 2. The flip cover 61 can open the drying air duct when the fan component 3 is running and close the drying air duct when the fan component stops running.

[0082] Specifically, when the flip cover 61 closes the drying air duct, the drying air duct forms the water storage cavity mentioned above, and the flip cover 61 serves as the bottom wall of the water storage cavity.

[0083] When the fan assembly 3 is running, the force of the circulating air overcomes gravity and opens the flap 61, thereby opening the drying duct. When the fan assembly 3 is not running, the flap 61 closes due to its own gravity, closing the drying duct and forming a water storage chamber for storing washing water. The flap 61 then serves as the bottom wall of the water storage chamber, preventing water from flowing out of the bottom of the water storage chamber.

[0084] Further, such as Figure 3-Figure 6As shown, the on / off assembly 6 further includes a bracket sleeve 62 having openings at both the top and the bottom, and the bracket sleeve 62 is fixedly mounted at the air inlet end of the air duct housing 2; specifically, an air duct adapter frame 9 is provided at the interface between the air duct housing 2 and the clothes processing drum 1, and the bracket sleeve 62 is fixedly mounted in the air duct adapter frame 9;

[0085] One end of the flip cover 61 is hinged at the bottom opening of the bracket sleeve 62, and the other end can open or close the bottom opening of the bracket sleeve 62 around its hinge axis.

[0086] In any of the above embodiments, the drainage assembly 5 includes a siphon tube installed at the air inlet end of the air duct housing 2;

[0087] like Figure 7 As shown, the siphon tube includes an outer tube 51 and an inner tube 52 that are sleeved together. The outer tube 51 is sealed at the top and has a first water inlet at the bottom. The inner tube 52 has a second water inlet at the top and a drain at the bottom. A water flow channel is formed between the outer tube 51 and the inner tube 52.

[0088] When the drying air duct is closed, if the water level in the water storage chamber is higher than the top of the outer tube 51, the siphon tube will produce a siphon reaction and the cleaning water in the water storage chamber can enter the inner tube 52 through the water flow channel and be discharged through the drain port of the inner tube 52, thereby realizing automatic drainage of the water in the water storage chamber.

[0089] In addition, in order to prevent the water level in the water storage chamber from being too high and flowing into the front side of the laundry treatment tub 1 , in this embodiment, the outer top wall of the outer tube 51 is arranged lower than the inner bottom wall of the middle air duct housing 22 .

[0090] In addition, in order to facilitate the detection of the liquid level in the water storage chamber, such as Figure 8 As shown, in this embodiment, the laundry processing drum further includes:

[0091] The liquid level detection component 7 and the controller, wherein the liquid level detection component is arranged in the drying air duct, and is used to detect the water level in the water storage chamber when the drying air duct is closed and feed back the detected water level signal to the controller and control the operating status of the fan component 3 and the water injection component 4 through the controller.

[0092] Specifically, the clothes treating device is preset with a first preset water level and a second preset water level, wherein the first preset water level is lower than the second preset water level;

[0093] When the water level in the water storage chamber is lower than the first preset water level, the liquid level detection component feeds back the detected water level signal to the controller, and the controller controls the water injection component 4 to open until the water level in the water storage chamber reaches the first preset water level;

[0094] When the water level in the water storage chamber reaches a first preset water level, the liquid level detection component feeds back the detected signal to the controller, and the controller controls the water injection component 4 to close and the fan component 3 to open;

[0095] After the fan assembly 3 runs for a preset period of time, the controller also controls the water injection assembly 4 to turn on and the fan assembly 3 to turn off. When the water level in the water storage chamber reaches a second preset water level, the liquid level detection assembly 7 feeds back the detected signal to the controller and controls the water injection assembly 4 to turn off through the controller.

[0096] More specifically, the liquid level detection assembly includes a liquid level probe, which includes a first probe 71 and a second probe 72; the distance from the first probe 71 to the bottom of the water storage chamber is less than the distance from the second probe 72 to the bottom of the water storage chamber; the first preset water level is the water level height when the water level in the water storage chamber reaches the bottom of the first probe 71, and the second preset water level is the water level height when the water level in the water storage chamber reaches the bottom of the second probe 72.

[0097] It is worth noting that, in this embodiment, the above-mentioned clothing processing device is a washing and drying machine. Of course, in some alternative embodiments, the clothing processing device may also be a dryer with only a drying function.

[0098] In any of the above embodiments, Figure 9 As shown, the laundry treatment drum 1 comprises an inner drum and an outer drum which are nested with each other, the inner drum is used to hold laundry, wherein the openings of the inner drum and the outer drum are arranged forward and a guide rib 8 is provided on the rear wall of the outer drum;

[0099] When drying clothes, the fan assembly 3 is turned on before the water injection assembly 4, and the air outlet 12 on the clothes treatment drum 1 is opened. The cleaning water injected by the water injection assembly 4 can flow through the air outlet 12 to the guide rib 8 on the rear wall of the outer drum and flow into the gap between the inner drum and the outer drum through the guide rib 8. Since the condensed water falling from the air outlet 12 falls between the inner drum and the outer drum along the guide rib 8, the condensed water will not wet the clothes in the inner drum.

[0100] In summary, in the embodiment of the present invention, when drying clothes, the flap 61 can be controlled by controlling the opening and closing of the fan assembly 3, without the need for additional drive device control; and when drying clothes, the liquid level detection assembly does not detect the water level. When the flap 61 is opened, the water injection assembly 4 is opened to inject condensed water into the water storage cavity formed, so that the hot air can perform heat exchange in the clothing processing drum 1.

[0101] While cleaning the fan impeller 31, the liquid level detection assembly operates to detect the water level. The water injection assembly 4 is activated to allow water to flow into the water storage chamber formed by the drying duct and the flap 61. Because the motors of the fan assembly 3 and the laundry treatment drum 1 are not activated, the flap 61 is closed, allowing condensed water to accumulate within the rear duct housing 21. When the water level reaches a first preset level, the water injection assembly 4 is closed and the fan assembly 3 is activated. Driven by the fan assembly 3, the fan impeller 31 rotates, allowing it to be immersed in water for cleaning. When the water level in the water storage chamber is detected to be below the first preset level, the water injection assembly 4 is activated to replenish water. This process continues until a set time, T1, is reached.

[0102] When the fan impeller 31 is cleaned, the fan impeller 31 stops working, and the water injection component 4 lets water into the drying air duct. When the water level in the water storage chamber reaches the second preset water level, the water injection component 4 is closed. At this time, the water level is higher than the highest position of the siphon tube, and the siphon effect occurs in the siphon tube. The water and hair debris in the drying air duct are discharged and finally discharged through the drain outlet of the siphon tube.

[0103] It is worth noting that in order to better clean the hair debris remaining in the drying duct, preferably, after the water in the drying duct is drained, the fan assembly 3 can be turned on again, and the flip cover 61 can be opened again under the action of wind, so that the water injection assembly 4 can once again let water into the drying duct, thereby completely washing away the hair debris remaining in the drying duct, thereby improving the cleaning effect.

[0104] On the other hand, an embodiment of the present invention further provides a Figure 10 The control method of the clothes processing device shown in the figure includes:

[0105] When entering the drying program, execute step S1;

[0106] The fan assembly 3 and the heating assembly are started, and the fan impeller 31 rotates to dry the clothes in the clothes processing drum 1;

[0107] When entering the fan blade cleaning program, execute step S1;

[0108] The water injection assembly 4 is turned on to inject cleaning water into the water storage chamber. When the water level in the water storage chamber reaches a first preset water level, the water injection assembly 4 is closed, and the fan assembly 3 is started to drive the fan impeller 31 to rotate in the water in the water storage chamber to clean the fan impeller 31.

[0109] The execution time of step S1 is preset to T1.

[0110] In any of the above-mentioned embodiments, during the execution of step S1, if the water level in the water storage chamber is lower than the first preset water level, the controller controls the water injection assembly 4 to open to replenish water in the water storage chamber until the water level reaches the first preset water level, so as to improve the cleaning effect of the fan impeller 31 and avoid incomplete cleaning of the fan impeller 31 due to insufficient water in the water storage chamber.

[0111] In any of the above embodiments, after the execution time of step S1 ends, step S2 is executed, wherein step S2 includes:

[0112] After the controller controls the fan assembly 3 to be turned off, the water injection assembly 4 is turned on to continue injecting water into the water storage chamber, and the liquid level detection assembly continues to detect the water level height in the water storage chamber;

[0113] If the liquid level detection component detects that the water level in the water storage chamber reaches the second preset water level, the controller controls the water injection component 4 to close, and the siphon tube generates a siphon reaction to drain the water in the water storage chamber;

[0114] The execution time of step S2 is preset to T2.

[0115] In any of the above embodiments, after the execution time of step S2 ends, step S3 is executed, wherein step S3 includes:

[0116] The controller controls the fan assembly 3 and the water injection assembly 4 to start again, wherein the fan assembly 3 is turned on before the water injection assembly 4 and there is a preset time T3 between the two, so that the hair debris remaining in the drying duct can be completely washed away by water, thereby improving the cleaning effect.

[0117] In any of the above embodiments, during the execution of step S1, the controller also controls the water injection component to turn on, wherein the fan component is turned on before the water injection component and the two are separated by a preset time T4, that is, under the drying program, condensed water is also injected into the clothing treatment drum 1, so that the condensed water condenses the high-humidity air in the clothing treatment drum 1 and converts it into low-temperature and low-humidity air, thereby improving the drying effect of the clothes.

[0118] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention.
