[0062] Background Introduction

[0063] Currently, very few solutions are available on the market for cleaning the detergent reservoir in washing machines. Users typically clean the reservoir only intermittently based on their daily habits, or they simply don't clean it at all. Over time, detergent deposits accumulate in the reservoir, affecting the detergent's effectiveness. The quality of the detergent greatly influences the cleaning result, making it difficult to effectively remove stains and pigments from clothes.

[0064] Based on this, such as Figures 1-6 As shown, a first aspect of this application provides a door assembly for a fabric processing device, comprising:

[0065] The liquid storage chamber 100 and the dispensing chamber 200 are provided. The liquid storage chamber 100 has a washing liquid inlet 101 and the dispensing chamber 200 has a washing liquid dispensing port 201. The washing liquid inlet 101 is used to add washing liquid to the liquid storage chamber 100 and the washing liquid dispensing port 201 is used to discharge the added washing liquid from the liquid storage chamber 100.

[0066] The dispensing module 300 includes a dispensing pump 301, a suction pipe 302, and a dispensing pipe 303 disposed in the dispensing chamber 200. One end of the suction pipe 302 is connected to the dispensing pump 301, and the other end is connected to the storage chamber 100. One end of the dispensing pipe 303 is connected to the dispensing pump 301, and the other end is connected to the washing liquid dispensing port 201. The dispensing pump 301 has a first working state and a second working state. If the dispensing pump 301 is controlled to be in the first working state, the liquid in the storage chamber 100 can be pumped into the suction pipe 302 by the pumping action of the dispensing pump 301 and discharged out of the door assembly in sequence through the dispensing pipe 303 and the washing liquid dispensing port 201. If the dispensing pump 301 is controlled to be in the second working state, the liquid outside the door assembly can be pumped into the dispensing pipe 303 by the pumping action of the dispensing pump 301 and discharged into the storage chamber 100 through the suction pipe 302.

[0067] When the door assembly is installed on the fabric processing equipment and is in the closed state, the door assembly has an inner side facing the fabric processing cylinder and an outer side facing away from the fabric processing cylinder. The washing liquid inlet 201 of the dispensing chamber 200 opens on the inner side of the door assembly, so that when the door assembly is installed on the fabric processing equipment, the washing liquid in the liquid storage chamber 100 can be dispensed into the fabric processing cylinder by switching the working state of the dispensing pump 301, or the washing water in the fabric processing cylinder can be pumped into the liquid storage chamber 100.

[0068] In this embodiment, the structure of the door assembly of the fabric processing equipment is improved. Based on the structural improvement, the different operating states of the dispensing pump are controlled. The suction and drainage control of the dispensing pump 301 can be realized according to the different operating states of the dispensing pump 301. Thus, by switching the working state of the dispensing pump 301, the washing liquid in the storage chamber 100 is dispensed into the fabric processing cylinder to realize the dispensing of detergent, or the washing water in the fabric processing cylinder is pumped into the storage chamber 100 to realize the self-cleaning of the storage chamber.

[0069] Specifically, when the fabric treatment equipment is washing clothes normally, the detergent in the storage chamber 100 can be pumped into the fabric treatment drum by controlling the dispensing pump 301 to operate in the first state. When it is necessary to clean the storage chamber 100, the washing water in the fabric treatment drum can be pumped into the storage chamber 100 to clean the storage chamber 100 by controlling the dispensing pump 301 to operate in the second state. After the water in the storage chamber 100 reaches a certain level, the dispensing pump 301 is controlled to operate in the first state again, so that the cleaning water in the storage chamber 100 is discharged into the fabric treatment drum through the dispensing port 201 and discharged through the drain port of the fabric treatment drum, thereby achieving the self-cleaning effect of the storage chamber 100.

[0070] Furthermore, in some possible implementations, the dispensing pump 301 is designed to be in a first operating state when it is supplied with a positive current and in a second operating state when it is supplied with a reverse current.

[0071] That is, by controlling the positive and negative currents supplied to the dispensing pump 301, the dispensing pump 301 can switch between different states, thereby realizing the dispensing pump 301's suction and drainage operations.

[0072] Specifically, the self-cleaning mode for the liquid storage chamber 100 during self-cleaning can be as follows:

[0073] The specific steps are as follows: First, the detergent in the storage chamber 100 is emptied by the dispensing pump 301. Then, the water inlet valve of the fabric treatment equipment is opened to allow water to enter the fabric treatment cylinder to a predetermined water level H1 (this predetermined water level is higher than the dispensing port 201 of the glass bowl 400). A reverse current is then applied to the dispensing pump 301. At this time, the water in the fabric treatment cylinder enters the storage chamber 100 from the dispensing port 201 under the reverse action of the dispensing pump 301 (dispensing port → dispensing pipe → dispensing pump → suction pipe → detergent storage chamber). When the high liquid level sensor in the storage chamber 100 detects that the water entering the storage chamber 100 has reached the predetermined water level value H2, the reverse current is stopped from being applied to the dispensing pump 301, and a forward current is applied to the dispensing pump 301 to empty the water in the storage chamber 100 into the fabric treatment cylinder. One suction and one dispensing of water in the cylinder is recorded as one cleaning process. The self-cleaning mode is completed after the storage chamber 100 has been cleaned for 3 complete cycles.

[0074] Furthermore, in some possible implementations, such as Figures 1-4 As shown, the detergent inlet 101 opens inside the door assembly;

[0075] in

[0076] The position of the detergent inlet 101, which opens inside the door assembly, is designed such that when the door assembly is installed on the fabric treatment equipment and the door assembly is in the closed state, the detergent inlet 101 can cooperate with the fabric treatment equipment and be sealed.

[0077] The detergent dispensing port 201, which opens inside the door assembly, is designed such that when the door assembly is installed in the fabric treatment equipment and the door assembly is in the closed state, the detergent dispensing port 201 can communicate with the fabric treatment cylinder of the fabric treatment equipment.

[0078] In this embodiment, the detergent inlet 101 is located inside the door assembly. This prevents the detergent inlet 101 from being exposed outside the fabric processing equipment when the door assembly is installed, resulting in a cleaner appearance for the fabric processing equipment. Furthermore, by designing the detergent inlet 101 to cooperate with the fabric processing equipment when the door assembly is closed, the cooperation between the door assembly and the fabric processing equipment when closed allows for a seal on the detergent inlet 101, eliminating the need for a separate detergent inlet cap.

[0079] Furthermore, in some possible implementations, such as Figures 1-4 As shown, the inner side of the door assembly has an outer ring area and an inner ring area with a protruding glass bowl 400. The outer ring area is provided with a detergent inlet 101, and the glass bowl 400 is provided with a detergent dispensing inlet 201.

[0080] The door assembly is installed on the fabric processing equipment. When the door assembly is in the closed state, the outer ring area of ​​the door assembly fits together with the edge of the fabric inlet of the fabric processing equipment to seal the detergent inlet 101 by utilizing the fit between the edge of the fabric inlet and the outer ring area. The glass bowl 400 on the inner ring area of ​​the door assembly at least partially protrudes into the fabric processing cylinder so that the detergent inlet 201 on the glass bowl 400 is connected to the fabric processing cylinder.

[0081] like Figure 3 As shown, in this embodiment, the detergent inlet is located in the outer ring area inside the door assembly. This allows the detergent inlet 101 to be sealed by the fit between the door assembly and the edge of the fabric inlet when the door assembly is closed, preventing the detergent inlet 101 from communicating with the fabric treatment cylinder. Simultaneously, in this embodiment, the detergent inlet 201 is located on the glass bowl 400 of the door assembly. This allows the detergent inlet 201 to communicate with the fabric treatment cylinder when the door assembly is closed. This enables the detergent inlet 201 to be pumped from the storage chamber 100 into the fabric treatment cylinder, or the washing water from the fabric treatment cylinder to be pumped from the storage chamber 100 into the storage chamber 100, through the combination of the detergent inlet 201 and the pump 301.

[0082] Furthermore, in some possible implementations, such as Figure 3 As shown, the glass bowl 400 has a top surface 401 in the projection direction and an outer peripheral surface 402 connecting the top surface 401 and the inner side of the door assembly;

[0083] The detergent inlet 201 is located on the outer peripheral surface 402 of the glass bowl 400 and in the area below the middle of the glass bowl 400 in the height direction.

[0084] In this embodiment, the washing liquid inlet 201 is positioned on the outer periphery of the glass bowl 400, and the height of the washing liquid inlet 201 is set below the middle of the glass bowl 400 in the height direction. In this way, when the fabric processing drum of the fabric processing device rotates to wash the fabric, the washing water in the fabric processing drum can be driven to the washing liquid inlet 201 of the glass bowl 400 by the rotation of the fabric processing drum, thereby realizing a cleaning operation of the washing liquid inlet 201 and avoiding the growth of bacteria due to excessive washing liquid residue at the washing liquid inlet 201.

[0085] The reason why the detergent inlet 201 is located on the outer circumference of the glass bowl 400 and below the middle in the height direction of the glass bowl 400 in this embodiment is mainly to utilize the washing water during laundry to achieve a self-cleaning operation of the detergent inlet 201. The reason why the detergent inlet 201 can be self-cleaned using washing water is mainly due to the rotation pattern of the fabric processing drum and the water level setting within the drum during laundry washing, which allows the detergent inlet 201, when positioned as described above, to fully utilize the washing water in the fabric processing drum to achieve a self-cleaning effect.

[0086] Preferably, the detergent inlet 201 is positioned in the height range of 2 / 1 to 1 / 4 of the glass bowl 400.

[0087] Furthermore, in some possible implementations, such as Figure 3 As shown, the liquid storage cavity 100 is a curved cavity that protrudes from the lower inner side of the door assembly and extends at least partially around the outer periphery of the glass bowl 400.

[0088] The washing liquid inlet 101, which is connected to the liquid storage chamber 100, is located at one end of the liquid storage chamber 100 in the extending direction.

[0089] In this embodiment, by setting the liquid storage cavity 100 as a curved cavity adapted to the outer periphery of the glass bowl 400, the size of the door assembly can be fully utilized to arrange the liquid storage cavity 100 with the largest possible volume. At the same time, the washing liquid inlet 101 is set at one end of the extension direction of the liquid storage cavity 100, so that the liquid storage cavity 100 can store as much washing liquid as possible.

[0090] Furthermore, in some possible implementations, such as Figures 1-4 As shown, the door assembly also includes an inner door assembly 1a and an outer door assembly 2a;

[0091] The inner component 1a has a slot in the middle and a liquid storage cavity 100 formed at the bottom of the inner side;

[0092] The glass bowl 400 and the outer door component 2a are respectively installed on the inner and outer sides of the inner door component 1a, and define the delivery cavity 200 between them and the slot of the inner door component 1a.

[0093] That is, the door assembly in this embodiment is assembled from multiple parts, which makes it easier to arrange the delivery module 300 and other corresponding modules inside the door assembly.

[0094] Furthermore, in some possible implementations, such as Figure 1 and Figure 4As shown, the inner door assembly 1a includes an inner door liner 1a1 and an inner door shell 1a2;

[0095] The exterior component 2a includes a decorative panel 2a1 and a decorative ring 2a2;

[0096] The decorative ring 2a2, decorative panel 2a1, door lining 1a1, door inner shell 1a2, and glass bowl 400 are assembled together to form the door body component.

[0097] Furthermore, in some possible implementations, such as Figure 1 and Figure 2 As shown, the dispensing cavity 200 includes a first cavity 2001 and a second cavity 2002 that are separated vertically. The first cavity 2001 is equipped with a display module, and the second cavity 2002 is equipped with a dispensing module 300.

[0098] The decorative panel 2a1 is a transparent panel so that the information displayed by the display module installed in the first cavity 2001 can be identified from the outside of the door assembly.

[0099] In this embodiment of the application, by setting the dispensing cavity 200 as a first cavity for installing the display module (not shown in the figure) and a second cavity for installing the dispensing module 300, and by setting the decorative panel 2a1 as a transparent panel, the user can more intuitively observe the information displayed by the display module from the outside of the fabric processing equipment.

[0100] It is worth noting that, because the roller-type fabric handling equipment is relatively low, by placing the first cavity for mounting the display module at the top, the user can easily observe the information displayed by the display module.

[0101] In summary, the embodiment of this application achieves self-cleaning control of the liquid storage chamber through a unique door-type dispensing structure. After the detergent is emptied, water is introduced into the inlet valve until the water level is higher than the dispensing position. The suction and drainage control of the dispensing pump is achieved by using forward and reverse current. When the high liquid level sensor detects the corresponding water level, the reverse pumping stops and the forward pumping starts to empty the water in the chamber. This process is repeated to achieve the purpose of cleaning the chamber.

[0102] Specifically, the detergent storage chamber 100 located at the bottom of the glass bowl 400 is used to meet the detergent dispensing needs for washing clothes. Secondly, the detergent storage chamber is also equipped with a self-cleaning mode. By changing the current direction of the dispensing pump 301 in the storage chamber 100, the dispensing pump 301 can dispense water in both directions. In the reverse direction, water in the fabric treatment tube is pumped into the storage chamber 100 for cleaning, and in the forward direction, water in the storage chamber 100 is dispensed into the fabric treatment tube. This process is achieved through the liquid extraction pipe 302 and the dispensing pipe 303, thereby achieving the purpose of self-cleaning the storage chamber 100.

[0103] Furthermore, the second aspect of this application also provides a fabric processing device, which has a fabric inlet and a door assembly provided in the first aspect of this application is connected to the fabric inlet.

[0104] Furthermore, in some possible implementations, such as Figure 1 As shown, the door assembly is also equipped with a hinge module and a door lock module. The door assembly is hinged to the fabric feeding port of the fabric processing equipment through the hinge module. When the door assembly is closed through the hinge module, it is locked to the fabric processing equipment through the door lock module.

[0105] Furthermore, in some possible embodiments, the fabric processing equipment described above is preferably a drum-type fabric processing equipment. Specifically, the drum-type fabric processing equipment is a drum-type washing machine or a drum-type washer-dryer combo.

[0106] Further, such as Figure 5 and Figure 6 As shown, a third aspect of this application also provides a self-cleaning control method for the liquid storage chamber of a fabric processing device, applied to the fabric processing device provided in the second aspect of this application, wherein the self-cleaning control method includes:

[0107] The dispensing pump is controlled to run a cleaning procedure at least once. The cleaning procedure includes controlling the dispensing pump to alternate between a first operating state and a second operating state.

[0108] Specifically, the dispensing pump is controlled to alternate between a first operating state and a second operating state, including:

[0109] The first working state of the dispensing pump is controlled to empty the liquid in the storage chamber;

[0110] After the liquid in the storage chamber is emptied, the fabric processing tube is controlled to enter water to the first preset water level. After the fabric processing tube reaches the first preset water level, the dispensing pump is controlled to run in the second working state to allow water to enter the storage chamber.

[0111] After the water level in the storage chamber reaches the second preset water level, the dispensing pump is controlled to run in the first working state again to empty the liquid in the storage chamber again.
