TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, and in particular to a clothes treatment device. BACKGROUND

[0002] The heat exchange flow channel of the clothes treatment device is provided with heat exchange components such as an evaporator and a condenser, which convert the humid air flow from the clothes treatment cavity into dry hot air flow. The dry hot air flow flows back into the clothes treatment cavity and exchanges heat with the wet clothes in the clothes treatment cavity to form humid air flow again. The humid air flow flows out of the clothes treatment cavity, and the process is repeated to dry the clothes.

[0003] The base of the clothes treatment device is provided with a space for storing water, which is used to collect condensate water removed during the conversion of the humid air flow in the heat exchange flow channel into dry hot air flow, or to collect water falling from the structural members in the heat exchange flow channel, and can also collect water transported in other channels of the clothes treatment device. However, due to the fluctuation of the water surface, the water level of the water stored in the base is easily misjudged, which leads to insufficient water storage that cannot meet the recycling requirements, or excessive water storage that has the risk of overflow.

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0056] The inventors discovered that when too much water is stored in the base of a garment processing device, there is a risk of overflow. Therefore, it is necessary to monitor the water level in the base and promptly drain the water to restore the water level, preventing overflow from affecting the normal operation of the garment processing device. In related technologies, the use of a single water level monitoring module to monitor the water level is affected by water surface fluctuations. This carries the risk of water overflow when the detected water level is higher than the actual water level, and the risk of insufficient water storage when the detected water level is lower than the actual water level, making it difficult to meet the needs of recycling. Based on this, this application provides a garment processing device.

[0057] like Figure 1 The diagram shown is a partial structural schematic of a garment processing device according to an embodiment of this application. The garment processing device includes a base assembly and a drain pump, as shown below. Figure 2 The diagram shown is a cross-sectional view of a drainage pump 500 mounted on a base assembly according to an embodiment of this application.

[0058] Figure 2 In the base assembly, a water collection chamber 101 is provided, which receives and stores water discharged from other channels of the garment processing equipment. A drain pump 500 is mounted on the base assembly, with at least a portion of the drain pump 500 located in the water collection chamber 101 to pump water from the chamber. For example, the drain pump 500 pumps water from the water collection chamber 101 to supply other structures of the garment processing equipment for water recycling; or, the water collection chamber 101 is connected to an external drainage space via the drain pump 500, which pumps water from the chamber 101 to discharge excess water, preventing water overflow from the chamber 101 and affecting the normal operation of the garment processing equipment.

[0059] It can be understood that when the water discharged from other channels of the laundry treating apparatus enters the water collecting cavity 101, the water flow entering will impact the water in the water collecting cavity 101, causing the water in the water collecting cavity 101 to fluctuate, and when the water in the water collecting cavity 101 is pumped by the drain pump 500, the vibration generated by the drain pump 500 will also cause the water in the water collecting cavity 101 to fluctuate, and in addition, the vibration generated when other structures of the laundry treating apparatus are working will also cause the water in the water collecting cavity 101 to fluctuate. In these cases, the fluctuating water surface in the water collecting cavity 101 will interfere with the determination of the water level in the water collecting cavity 101, for example, when a single water level sensing module 200 is used, the single water level sensing module 200 can only sense the water level in a local area, and the water level sensed by the single water level sensing module 200 does not represent the water level in the entire water collecting cavity 101, so when the single water level sensing module 200 does not detect that the water level in its corresponding area exceeds the preset water level, the water level in other areas of the water collecting cavity 101 can have already exceeded the preset water level, and there is a risk of water overflow.

[0060] In combination with Figure 3 and Figure 4 , the laundry treating apparatus further comprises a plurality of water level sensing modules 200, which are installed on the base assembly, wherein the plurality of water level sensing modules 200 are distributed at intervals, and each water level sensing module 200 is used to sense the water level in a corresponding area of the water collecting cavity 101, so as to determine the water level state in the water collecting cavity 101 according to the water level of at least one area in the water collecting cavity 101 obtained.

[0061] In the embodiments of the present application, by providing a plurality of water level sensing modules 200 to monitor the water levels in a plurality of areas in the water collecting cavity 101, the plurality of water level sensing modules 200 can cover more areas to be monitored, reducing the existence of monitoring dead angles. The water level in any one of the plurality of areas corresponding to the plurality of water level sensing modules 200 can be monitored, and when the water level in any one of the areas is higher than the preset water level, it can be used to determine that there is a risk of water overflow in the water collecting cavity 101, so as to timely drain the water in the water collecting cavity 101 to prevent the situation that the monitoring area range is too small when a single water level sensing module 200 is used and the water level in the water collecting cavity 101 cannot be fully monitored, or the water level is interfered with by the water surface fluctuation, and the water level in the water collecting cavity 101 is misjudged.

[0062] As shown in Figure 4 , the part of the base assembly surrounding the outer periphery of the drain pump 500 is divided into a plurality of monitoring areas 102, and the plurality of monitoring areas 102 are provided one by one corresponding to the plurality of areas of the water collecting cavity 101. At least two monitoring areas 102 are provided with water level sensing modules 200, and the more the number of water level sensing modules 200, the more areas they can cover, and the water level in the water collecting cavity 101 is more comprehensively monitored. Optionally, in combination withFigure 4 and Figure 5 The drainage pump 500 has a first water inlet end 510 for pumping water, and a plurality of monitoring areas 102 are divided around the first water inlet end 510 at equal central angles, Figure 4 In this embodiment, the boundary line M and the boundary line N intersect and are perpendicular, i.e., four monitoring areas 102 are divided.

[0063] In other embodiments, the water level sensing module 200 provided in each monitoring area 102 is located in the area farthest from the drainage pump 500, so that when the number of water level sensing modules 200 is multiple, the multiple water level sensing modules 200 are located in areas far from each other, so that the multiple water level sensing modules 200 can cover the water level of more areas.

[0064] Optionally, when some of the monitoring areas 102 are provided with water level sensing modules 200, and in the case of selecting the same number of monitoring areas 102 to set water level sensing modules 200, the center lines of the selected multiple monitoring areas 102 provided with water level sensing modules 200 are the longest. For example, the part of the base assembly surrounding the outer periphery of the drainage pump 500 is divided into four monitoring areas 102, which are the first monitoring area 1021, the second monitoring area 1022, the third monitoring area 1023, and the fourth monitoring area 1024. In the left-right direction X of the laundry treatment apparatus, the first monitoring area 1021 and the second monitoring area 1022 are respectively provided on opposite sides of the drainage pump 500, and in the front-rear direction Y of the laundry treatment apparatus, the third monitoring area 1023 and the fourth monitoring area 1024 are respectively provided on opposite sides of the drainage pump 500 (the third monitoring area 1023 is on the front side of the drainage pump 500, and the fourth monitoring area 1024 is on the rear side of the drainage pump 500). When the laundry treatment apparatus has two water level sensing modules 200, two of the four monitoring areas 102 are selected to set water level sensing modules 200, then the two monitoring areas 102 provided opposite each other are selected to set water level sensing modules 200, i.e., the first monitoring area 1021 and the second monitoring area 1022 are selected to set water level sensing modules 200, or the third monitoring area 1023 and the fourth monitoring area 1024 are selected to set water level sensing modules 200. When the laundry treatment apparatus has three water level sensing modules 200, three of the four monitoring areas 102 are selected to set water level openings 121a, then any three of the four monitoring areas 102 are selected to set water level openings 121a.

[0065] It can be understood that when the clothes treatment equipment needs to be installed into a use scene, the space available to the clothes treatment equipment in the front-rear direction Y is relatively cramped due to the installation space, and in the case where the base assembly has the four monitoring areas 102 of the first monitoring area 1021, the second monitoring area 1022, the third monitoring area 1023, and the fourth monitoring area 1024, when the number of the water level sensing modules 200 is two, the first monitoring area 1021 and the second monitoring area 1022 that are oppositely arranged in the left-right direction X of the clothes treatment equipment can be selected to be respectively provided with the water level sensing modules 200, when the number of the water level sensing modules 200 is three, the first monitoring area 1021 and the second monitoring area 1022 that are oppositely arranged in the left-right direction X of the clothes treatment equipment can be selected to be respectively provided with the water level sensing modules 200, and one of the four monitoring areas 102 is selected to be provided with one water level sensing module 200.

[0066] In other embodiments, the part of the base assembly surrounding the outer periphery of the drainage pump 500 can be divided into a larger number of monitoring areas 102, for example, the number of the monitoring areas 102 is five, six, etc., and correspondingly, three, four of them can be selected to be provided with the water level sensing modules 200.

[0067] The clothes treatment equipment has an inner tub 10, and the inner tub 10 has a clothes treatment cavity for accommodating wet clothes, please refer to Figure 4 The base assembly also has a heat exchange channel 104 and a backflow flow channel 103, and the wet and cold gas after the wet clothes in the clothes treatment cavity are treated enters the heat exchange channel 104, and the heat exchange channel 104 is provided with a heat exchange assembly, which is used to remove water in the wet and cold gas and convert the wet and cold gas into dry and hot gas, and the dry and hot gas is backflowed into the clothes treatment cavity again to perform drying treatment on the wet clothes in the clothes treatment cavity. Among them, the backflow flow channel 103 is respectively communicated with the heat exchange channel 104 and the water collecting cavity 101, and the water in the heat exchange channel 104 can be transported to the water collecting cavity 101 for storage through the backflow flow channel 103, when the water in the water collecting cavity 101 is full, there may be a case that excess water overflows from the backflow flow channel 103 into the heat exchange channel 104, increasing the humidity in the heat exchange channel 104, and there may also be a case that it splashes to the heat exchange assembly to interfere with the work of the heat exchange assembly. By setting a plurality of water level sensing modules 200, the water level in the water collecting cavity 101 is more comprehensively monitored to prevent overflow from the water collecting cavity 101 into the heat exchange channel 104.

[0068] In some embodiments, in the front-rear direction Y of the laundry treating apparatus, the heat exchange channel 104 is located at the rear side of the water collecting cavity 101, and in the vertical direction G, the backflow flow channel 103 is located below the heat exchange channel 104 to receive the water flowing out of the heat exchange channel 104 and deliver the water to the water collecting cavity 101, forming a smooth water flow transmission path. In this way, in the left-right direction X of the laundry treating apparatus, more space can be reserved for the backflow flow channel 103, so that the backflow flow channel 103 can also be used to store a certain amount of water, and it is also convenient to design the shape of the backflow flow channel 103, so that the water in the backflow flow channel 103 can enter the water collecting cavity 101 at a suitable angle, reducing the interference of the water in the backflow flow channel 103 with the water in the water collecting cavity 101 during the process of entering the water collecting cavity 101. At the same time, it is also convenient to widen the size of the water collecting cavity 101 in the left-right direction X of the laundry treating apparatus, and to reduce the space occupied by the water collecting cavity 101 in the front-rear direction Y of the laundry treating apparatus under the condition of meeting the space requirement of the drain pump 500.

[0069] In some embodiments, the base assembly includes a base 110 having the backflow flow channel 103 and a water pump cover plate 120 covering the base 110 in the vertical direction G, and the water pump cover plate 120 and the base 110 enclose the water collecting cavity 101, and the water level sensing module 200 and the drain pump 500 are both mounted on the water pump cover plate 120. Mounting the drain pump 500 and the water level sensing module 200 on the same water pump cover plate 120 facilitates assembly and facilitates the design of the positions of multiple water level sensing modules 200 relative to the drain pump 500 so that the multiple water level sensing modules 200 are in more suitable positions to monitor the water level of the corresponding regions of the water collecting cavity 101.

[0070] In some embodiments, the water pump cover plate 120 has a mounting opening 122a and multiple water level openings 121a respectively communicating with the water collecting cavity 101. The drain pump 500 is mounted on the water pump cover plate 120, and the drain pump 500 penetrates the mounting opening 122a and extends into the water collecting cavity 101 to extract water from the water collecting cavity 101. The multiple water level sensing modules 200 are installed on the water pump cover plate 120 one by one corresponding to the multiple water level openings 121a.

[0071] In some embodiments, in combination with Figure 5 and Figure 6 , the water pump cover plate 120 includes a main body portion 121 having the water level openings 121a, and the multiple water level sensing modules 200 are installed on the main body portion 121. The laundry treating apparatus further includes a first sealing ring 300 clamped between the main body portion 121 and the base 110 to seal the gap between the main body portion 121 and the base 110.

[0072] Optionally, the main body 121 is flat, and the main body 121 is parallel to the horizontal direction, so that multiple water level sensing modules 200 can be installed on the same horizontal plane, so that the multiple water level sensing modules 200 are at the same height to detect the water level of the corresponding area in the water collecting cavity 101, and in the case that the water collecting cavity 101 is filled with water, the water level of the area corresponding to the main body 121 of the water collecting cavity 101 is also uniform.

[0073] In some embodiments, as shown in Figure 7 The bottom wall surface of the water collecting cavity 101 is a receiving bottom surface 112b, which is located below the water level opening 121a in the vertical direction G, and is the lowest wall surface of the water collecting cavity 101 in the vertical direction G. In the case that the water collecting cavity 101 stores water, the receiving bottom surface 112b receives water. The water pump cover plate 120 includes a mounting portion 122 connected to the main body 121, and the mounting portion 122 has a mounting opening 122a. The drain pump 500 is mounted on the mounting portion 122 and extends into the water collecting cavity 101 through the mounting opening 122a.

[0074] Optionally, the mounting portion 122 extends towards the side where the receiving bottom surface 112b is located and forms a mounting recess. The bottom wall of the mounting recess is provided with the mounting opening 122a. The drain pump 500 includes a first water inlet end 510. The drain pump 500 is arranged in the mounting recess, and the first water inlet end 510 of the drain pump 500 extends through the mounting opening 122a towards the receiving bottom surface 112b. The first water inlet end 510 of the drain pump 500 extends to the lowest part of the water collecting cavity 101, so that the drain pump 500 can more fully extract water from the water collecting cavity 101, and prevent the operation of the drain pump 500 from being affected when the amount of water stored in the water collecting cavity 101 is too small.

[0075] The laundry treating apparatus further includes a second sealing ring 400 arranged between the mounting portion 122 and the drain pump 500 to seal the gap between the mounting portion 122 and the drain pump 500. Correspondingly, the first sealing ring 300 is arranged around the outer periphery of the mounting portion 122, and the second sealing ring 400 is arranged around the inner periphery of the mounting portion 122 to form a seal, thereby preventing water leakage from the water collecting cavity 101.

[0076] In some embodiments, the distance between the first water inlet end 510 of the drain pump 500 and the receiving bottom surface 112b is H, and 1mm≤H≤20mm. In this distance range, the distance between the first water inlet end 510 of the drain pump 500 and the receiving bottom surface 112b is appropriate, so that the drain pump 500 can smoothly extract water from the water collecting cavity 101 and more fully extract water from the water collecting cavity 101. Optionally, the receiving bottom surface 112b is a plane parallel to the plane of the main body 121.

[0077] In some embodiments, the backflow channel 103 has a backwater inlet 111b communicating with the heat exchange channel 104, the base assembly defines a backflow bottom surface 112c of the backflow channel 103, water falling through the backwater inlet 111b falls onto the backflow bottom surface 112c and enters the sump cavity 101 guided by the backflow bottom surface 112c. The backflow bottom surface 112c has a backflow edge w facing the receiving bottom surface 112b, in the vertical direction G, the receiving bottom surface 112b is located below the backflow edge w, so that water in the backflow channel 103 can more fully and efficiently enter the sump cavity 101. Optionally, the first water inlet end 510 of the drain pump 500 extends below the backflow edge w, so that the drain pump 500 can more fully extract water in the sump cavity 101.

[0078] In some embodiments, at least part of the backflow bottom surface 112c is inclined to the side where the receiving bottom surface 112b is located in the direction of gravity, so that water in the backflow channel 103 can more smoothly enter the sump cavity 101. Optionally, the backflow bottom surface 112c includes a first backflow area 12a and a second backflow area 12b, the first backflow area 12a is arranged towards the backwater inlet 111b, and the second backflow area 12b is arranged on the side of the first backflow area 12a towards the sump cavity 101, the second backflow area 12b has a backflow edge w, water falling through the backwater inlet 111b enters the sump cavity 101 in sequence through the first backflow area 12a and the second backflow area 12b, in the vertical direction G, the first backflow area 12a is located above the second backflow area 12b, and at least one of the first backflow area 12a and the second backflow area 12b is inclined, so as to guide water to flow smoothly into the sump cavity 101. Further, the backflow bottom surface 112c further includes an inclined transition area connecting the first backflow area 12a and the second backflow area 12b, and the connection between the second backflow area 12b and the receiving bottom surface 112b forms a stepped surface.

[0079] In some embodiments, as Figure 8As shown, the base 110 includes a first bottom shell 111 and a second bottom shell 112. The first bottom shell 111 includes a first side wall 1111, and the second bottom shell 112 includes a second side wall 1121. The water pump cover 120 is installed on the first side wall 1111 and the second side wall 1121, and the water pump cover 120, the first bottom shell 111 and the second bottom shell 112 together form a water collection cavity 101.
