Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and in particular to a clothing processing device and a combined clothing processing equipment. Background Technology

[0002] Currently, users have increasingly higher requirements for the hygiene of clothing processing. They usually need to distinguish the types of clothing and then clean them separately. To improve efficiency, multi-roller clothing processing devices can be used to clean different types of clothing at the same time.

[0003] However, existing multi-roller garment processing devices usually require corresponding liquid storage boxes for different rollers. The liquid storage boxes are connected to the corresponding rollers through corresponding dispensing pipes. This increases the difficulty of laying out the internal pipes of the garment processing device and occupies more internal space, which is not conducive to the miniaturization of the garment processing device. Utility Model Content

[0004] The clothing processing device and combined clothing processing equipment provided in this application can simplify the internal piping of the clothing processing device, reduce design difficulty, and reduce the size of the clothing processing device.

[0005] The first aspect of this application provides a garment handling apparatus, comprising:

[0006] Box;

[0007] Two rollers are arranged side by side in a horizontal direction inside the box.

[0008] The enclosure includes:

[0009] Front roller;

[0010] The rear plate is spaced apart from the front plate along the depth direction of the box body, and the two rollers are located between the front plate and the rear plate;

[0011] Detergent dispensing components include:

[0012] Two detergent dispensing ports are provided for dispensing detergent.

[0013] Two connecting pipes, each of which is connected to one of the two detergent dispensing ports;

[0014] A liquid storage box is disposed in the housing, located between the two rollers and below the two rollers along the height direction of the housing. The liquid storage box has a first liquid inlet, which is connected to the two connecting pipes so that the liquid storage box is connected to the detergent dispensing port.

[0015] Water inlet components, including:

[0016] A first water inlet pipe is located between the two rollers and above the two rollers along the height direction of the tank. The first water inlet pipe extends along the depth direction of the tank and is used to connect a water source and one of the rollers.

[0017] The second water inlet pipe is located between the two rollers and above the two rollers along the height direction of the tank. The second water inlet pipe extends along the depth direction of the tank and is used to connect the water source and the other roller.

[0018] The detergent dispensing component also includes:

[0019] A one-way pipe connector is located between the first water inlet pipe and the second water inlet pipe, and above the two rollers along the height direction of the box. The one-way pipe connector has a second liquid inlet, a first liquid outlet and a second liquid outlet. The second liquid inlet is connected to the liquid storage box, the first liquid outlet is connected to the first water inlet pipe, and the second liquid outlet is connected to the second water inlet pipe.

[0020] A dispensing pump is used to pump the detergent from the storage box into the one-way pipe joint.

[0021] In the depth direction of the housing, the distance between the liquid storage box and the front plate is less than the distance between the liquid storage box and the rear plate, and the distance between the one-way pipe connector and the front plate is less than the distance between the one-way pipe connector and the rear plate.

[0022] The garment processing device of this application features a liquid storage box connected to a one-way pipe connector. The two outlets of the one-way pipe connector can be connected to two water inlet pipes, allowing detergent from the storage box to enter each of the two inlet pipes and then flow into the corresponding drums via the water flow from each pipe, thus automatically dispensing detergent. In other words, one liquid storage box can dispense detergent into multiple drums, reducing the number of internal components, optimizing piping layout, increasing the integration of the garment processing device, and consequently reducing its overall size. Furthermore, since the liquid storage box is located below the two drums, while the first and second water inlet pipes and the one-way pipe connector are located above the two drums, and the storage box and one-way pipe connector are positioned close to the front panel in the depth direction of the housing, this effectively utilizes the space between the two drums, making the internal structure of the garment processing device more compact. It also reduces the length of the two connecting pipes, facilitating rapid detergent flow from the detergent dispensing port into the storage box. Additionally, the reduced length of the connecting pipes minimizes detergent loss caused by residue adhering to the inner walls of the connecting pipes. In addition, it can shorten the distance between the liquid storage box and the one-way pipe joint, thereby shortening the pipe length between the liquid storage box and the one-way pipe joint, which can reduce the detergent delivery loss and the load on the dosing pump for pumping detergent.

[0023] In one possible implementation, along the depth direction of the housing, the distance between the liquid storage box and the front plate is L1, and the distance between the one-way connector and the front plate is L2, and L1 and L2 satisfy the following relationship:

[0024] 1.2L1≤L2≤7.5L1.

[0025] By appropriately setting the ratio of the distance between the reservoir and the front plate to the distance between the one-way connector and the front plate, the distance between the reservoir and the one-way connector can be prevented from being too large, thus reasonably limiting the length of the pipe between the reservoir and the one-way connector and reducing the difficulty of pipe layout within the tank. Furthermore, since detergent adheres to the inner wall of the delivery pipe during the transportation process before mixing with water, resulting in some detergent loss, shortening the pipe length between the reservoir and the one-way connector can also reduce detergent loss due to an excessively long transportation path within the delivery pipe. When L2 < 1.2L1, the distance between the one-way connector and the front plate is too small. When the pipe connecting the reservoir and the one-way connector bends at the one-way connector, it is prone to interference with the front plate, causing the pipe to be squeezed by the front plate, affecting the normal transportation function of the pipe, and also making the pipe prone to fatigue due to long-term pressure, thus leading to pipe damage. When L2 > 7.5L1, the distance between the one-way connector and the front plate is too large, resulting in an excessively large distance between the liquid storage box and the one-way connector. This necessitates increasing the length of the pipe connecting the liquid storage box and the one-way connector, which increases the detergent delivery loss and also increases the workload of the dispensing pump.

[0026] In one possible implementation, the value of L1 ranges from 20mm to 50mm.

[0027] When L1 ranges from 20mm to 30mm, the distance between the liquid reservoir and the front panel is small, resulting in a compact design that facilitates miniaturization of the garment handling device. When L1 ranges from 30mm to 40mm, appropriately increasing the distance between the liquid reservoir and the front panel allows the pipe connecting the liquid reservoir and the one-way connector to avoid other components on the front panel. When L1 ranges from 40mm to 50mm, the distance between the liquid reservoir and the front panel is relatively large, facilitating the installation of a connecting pipe between the front panel and the liquid reservoir, connecting the detergent dispensing port and the liquid reservoir. When L1 is less than 20mm, the distance between the liquid reservoir and the front panel is small, making it difficult to install a connecting pipe, or requiring a smaller pipe diameter. This reduces detergent delivery efficiency and makes the device susceptible to internal air pressure in the liquid reservoir, hindering detergent flow. In this case, even if the one-way connector is placed close to the liquid reservoir, the dispensing pump will struggle to pump detergent to the one-way connector. When L1 is greater than 50mm, the distance between the liquid storage box and the front plate is large, requiring the length of the connecting pipe to be extended. This results in a longer flow path for the detergent, increasing the detergent delivery loss. In this case, even if the one-way pipe connector is placed close to the liquid storage box, the detergent delivery loss is still high.

[0028] In one possible implementation, the value of L2 ranges from 60mm to 150mm.

[0029] When L2 ranges from 60mm to 90mm, the smaller distance between the one-way connector and the front plate shortens the pipe length between the liquid reservoir and the one-way connector, helping to reduce detergent delivery loss and facilitating the miniaturization of the garment handling device. When L2 ranges from 90mm to 120mm, appropriately increasing the distance between the one-way connector and the front plate creates sufficient space to accommodate the section of the inlet pipe that connects to the drum after passing through the one-way connector, making the inlet pipe layout easier. When L2 ranges from 120mm to 150mm, the larger distance between the one-way connector and the front plate allows for more flexible inlet pipe placement, providing space for further optimization of the pipe layout. When L2 is less than 60mm, the pipe connected to the one-way connector is easily squeezed by the front plate, which is detrimental to detergent delivery and can easily damage the pipe. When L2 is greater than 150mm, the distance between the one-way pipe joint and the front plate is too large, which will result in an excessively long pipe length between the dispensing pump and the one-way pipe joint, leading to increased detergent delivery loss and increased workload of the dispensing pump.

[0030] In one possible implementation, the one-way connector includes:

[0031] The liquid inlet section has two opposite ends, one end of which has a second liquid inlet and the other end of which has a third liquid outlet;

[0032] The first liquid distribution section has two opposite ends. One end of the first liquid distribution section has a first liquid distribution inlet, which is connected to the third liquid outlet. The other end of the first liquid distribution section has the first liquid outlet.

[0033] The second liquid distribution section has two opposite ends. One end of the second liquid distribution section has a second liquid distribution inlet, which is connected to the third liquid outlet. The other end of the second liquid distribution section has a second liquid outlet.

[0034] The dimensions of the first dispensing section along its own axial direction are equal to the dimensions of the second dispensing section along its own axial direction.

[0035] By setting the lengths of the first and second dispensing sections to be equal, the detergent travels through the first and second dispensing sections from the inlet section into the first and second water inlets respectively along the same path length. This reduces detergent transport losses along different paths, thereby reducing factors that affect the amount of detergent dispensed in different drums and helping to achieve precise quantitative dispensing of detergent.

[0036] In one possible implementation, the portion of the first dispensing section near the first inlet pipe is radially recessed and extends in the direction of detergent flow to form a duckbill valve; and / or, the portion of the second dispensing section near the second inlet pipe is radially recessed and extends in the direction of detergent flow to form a duckbill valve.

[0037] The portion of the first dispensing section closest to the first inlet pipe tapers inwards radially and extends in the direction of detergent flow, thus forming a duckbill valve. The outlet of the duckbill valve forms the aforementioned first outlet. In this way, after the detergent flows out from the duckbill valve, it mixes with the water flow in the first inlet pipe. Due to the action of the duckbill valve, the water flow in the first inlet pipe cannot enter the interior of the first dispensing section, and therefore cannot enter the storage box through the one-way connector, preventing overflow from the storage box. Similarly, the portion of the second dispensing section closest to the second inlet pipe also forms a duckbill valve, preventing water from the second inlet pipe from entering the storage box through the second dispensing section, thereby preventing overflow from the storage box.

[0038] In one possible implementation, the first dispensing section includes:

[0039] A first inner tube, the first inner tube having the first liquid outlet;

[0040] A first outer tube surrounds the outer periphery of the first inner tube, and a first installation gap exists between the first inner tube and the first outer tube.

[0041] The first water inlet pipe includes:

[0042] A first main body, one end of which is connected to the water source, and the other end of which is connected to a roller;

[0043] A first connector extends radially along the first main body, with one end connected to the first main body and the other end extending into the first mounting gap, so that the first liquid distribution section is connected to the first water inlet pipe.

[0044] By configuring the first dispensing section as inner and outer tubes, a first installation gap is formed between the first inner tube and the first outer tube. During assembly of the first dispensing section and the first water inlet pipe, this first installation gap guides the assembly and prevents mistaken assembly. Furthermore, when the first water inlet pipe is in the water-inlet state, since the first connector of the first water inlet pipe is located within the space enclosed by the first inner tube and the first outer tube, water leakage from the first connector can be reduced or prevented. Additionally, because the first inner tube is inserted into the first connector, when detergent flows from the first inner tube into the first connector, the detergent can avoid the joint between the first inner tube and the first connector, preventing detergent leakage from that joint.

[0045] In one possible implementation, the second dispensing section includes:

[0046] The second inner tube has the second liquid outlet;

[0047] The second outer tube surrounds the outer periphery of the second inner tube, and there is a second installation gap between the second inner tube and the second outer tube.

[0048] The second water inlet pipe includes:

[0049] The second main body is connected at one end to the water source and at the other end to another roller.

[0050] The second insertion part extends radially along the second main body part. One end of the second insertion part is connected to the second main body part, and the other end of the second insertion part extends into the second mounting gap so that the second liquid distribution section is connected to the second water inlet pipe.

[0051] Similarly, by setting the second dispensing section in the form of inner and outer tubes, a second installation gap is formed between the second inner tube and the second outer tube. During the assembly of the second dispensing section and the second inlet pipe, this second installation gap serves to guide assembly and prevent mistaken insertion. Furthermore, when the second inlet pipe is in the water-inlet state, since the second connector of the second inlet pipe is located within the space enclosed by the second inner tube and the second outer tube, water leakage from the second connector can be reduced or prevented. Additionally, because the second inner tube is inserted into the second connector, when detergent flows from the second inner tube into the second connector, the detergent can avoid the joint between the second inner tube and the second connector, preventing detergent leakage from that joint.

[0052] In one possible implementation, the housing includes:

[0053] A crossbeam connects the upper parts of the front plate and the rear plate along the height direction of the housing. The projection of the crossbeam along the height direction of the housing is located between the axes of the two rollers. The first water inlet pipe and the second water inlet pipe are located on opposite sides of the crossbeam along the width direction of the housing. The crossbeam includes:

[0054] The front section, one end of which is connected to the front panel;

[0055] The rear section has one end connected to the other end of the front section, and the other end of the rear section is connected to the rear plate.

[0056] In the height direction of the housing, the upper surface of the front section is located below the upper surface of the rear section, the one-way pipe joint overlaps the upper part of the front section, and part of the first water inlet pipe and part of the second water inlet pipe are located below the rear section and overlap with the rear section.

[0057] The upper surface of the front section of the crossbeam is positioned lower than the upper surface of the rear section. A one-way pipe connector is then overlapped on the upper surface of the front section, and a portion of the inlet pipe is overlapped in the middle of the crossbeam. This design creates space at the front of the crossbeam for the one-way pipe connector and provides support, ensuring the stability of the detergent dispensing assembly. Additionally, the inlet pipe is also overlapped at the rear of the crossbeam, which is used to secure the pipe and ensure its stability.

[0058] In one possible implementation, in the depth direction of the housing, the first water inlet pipe portion is located between the one-way pipe joint and the front plate, and is fixedly connected to the front section;

[0059] In the depth direction of the housing, the second water inlet pipe section is located between the one-way pipe joint and the front plate, and is fixedly connected to the front section.

[0060] By fixing the portions of the first and second water inlet pipes located between the front plate and the one-way pipe connector to the front section of the crossbeam, the portions of the first and second water inlet pipes located at the front section of the crossbeam can be further secured, thereby ensuring the overall stability of the first and second water inlet pipes and preventing damage to the first and second water inlet pipes due to vibration when the garment processing device performs the dehydration process.

[0061] A second aspect of this application provides a combined garment processing device, comprising:

[0062] First garment processing device;

[0063] A second garment processing device, wherein the second garment processing device is any of the garment processing devices described above, and the second garment processing device is detachably disposed above the first garment processing device.

[0064] In this way, users can choose the appropriate laundry equipment according to their actual needs, which can meet the diverse needs of different users.

[0065] Compared with the prior art, the beneficial effects of this application are as follows:

[0066] The garment processing device of this application features a liquid storage box connected to a one-way pipe connector. The two outlets of the one-way pipe connector can be connected to two water inlet pipes, allowing detergent from the storage box to enter the two water inlet pipes and then flow into the corresponding drums via the water flow from each pipe, thus automatically dispensing detergent. In other words, one liquid storage box can dispense detergent into multiple drums, reducing the number of internal components, optimizing piping layout, increasing the integration of the garment processing device, and consequently reducing its overall size. Furthermore, since the liquid storage box is located below the two drums, while the first water inlet pipe, the second water inlet pipe, and the one-way pipe connector are located above the two drums, and the storage box and one-way pipe connector are positioned close to the front panel in the depth direction of the housing, this effectively utilizes the space between the two drums, making the internal structure of the garment processing device more compact. It also reduces the length of the two connecting pipes, facilitating rapid detergent flow from the detergent dispensing port into the storage box. Additionally, the reduced length of the connecting pipes minimizes detergent loss caused by residue adhering to the inner walls of the connecting pipes. In addition, it can shorten the distance between the liquid reservoir and the one-way connector, thereby shortening the pipe length between the liquid reservoir and the one-way connector, which can reduce detergent delivery loss and the load on the dosing pump for delivering detergent.

[0096] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0097] In this application, the terms "upper," "rear," "inner," "outer," and "middle," etc., indicate orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing the present invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0098] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0099] Furthermore, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable link, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection via an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0100] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0101] Multi-drum garment handling units meet users' increasingly sophisticated hygiene needs, allowing them to separate garments by type and use different drums to clean different types of clothing simultaneously. For example, trousers can use a separate drum, underwear a separate drum, and socks a separate drum. For families with infants and young children, infant clothing can also use a separate drum. In practical applications, not all drums are usually used simultaneously, and when multiple drums run the spin-dry / dry cycle at the same time, the garment handling unit may operate beyond its power capacity, posing a safety hazard. Therefore, multi-drum garment handling units are typically designed so that each drum can operate independently. That is, when one drum is running, the others may not be running, or when one drum is running a spin-dry cycle, the others can run washing, rinsing, or other programs different from the spin-dry cycle.

[0102] To enable independent operation of different drums in a multi-drum garment processing device, each drum needs to be able to independently receive water, spin-dry, and dispense detergent. The inventors attempted to achieve independent detergent dispensing for each drum by providing separate inlet and outlet water pipes and equipping each inlet pipe with a corresponding detergent dispensing component. However, this resulted in complex and disorganized internal piping, making pipework difficult to install and occupying a significant amount of internal space, reducing the utilization rate of the internal space and leading to a larger overall size and greater space requirements for the garment processing device.

[0103] To address the aforementioned technical problems, this application provides a garment processing device. In this device, a liquid storage box for storing detergent is connected to a one-way pipe connector for conveying detergent. The two outlets of the one-way pipe connector can be connected to two water inlet pipes, allowing the detergent in the liquid storage box to enter the two water inlet pipes through the one-way pipe connector and then flow into the corresponding drums through the water flow in the two water inlet pipes, thus completing the automatic dispensing of detergent. In other words, one liquid storage box can dispense detergent into multiple drums, reducing the number of internal components of the garment processing device, thereby optimizing the pipe layout, improving the integration of the garment processing device, and ultimately reducing the overall size of the garment processing device.

[0104] It should be noted that the garment handling device can be a washing machine, dryer, or washer-dryer combo; this application does not specifically limit this. The detergent can be a cleaning agent used for cleaning clothes, such as laundry detergent. The detergent can also be a garment care agent, such as fabric softener or disinfectant.

[0105] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0107] In some embodiments, the garment processing device 1 includes a housing 11, which may be the outer shell of the garment processing device 1 or a combination of the outer shell of the garment processing device 1 and a support frame.

[0108] In some embodiments, the housing 11 includes a front panel 111, a rear panel 112, a left side panel 113, a right side panel 114, and a top panel 115. The front panel 111 and the rear panel 112 are spaced apart and parallel to each other, as are the left side panel 113 and the right side panel 114. The left side panel 112 is located to the left of the front panel 111 and the rear panel 112, with one end connected to the front panel 111 and the other end connected to the rear panel 112. The right side panel is located to the right of the front panel 111 and the rear panel 112, with one end connected to the front panel 111 and the other end connected to the rear panel 112. The front panel 111, the left side panel 113, the rear panel 112, and the right side panel 114 form a ring-shaped structure. The top panel 115 covers the top of this ring-shaped structure. The front panel 111, the rear panel 112, the left side panel 113, the right side panel 114, and the top panel 115 together form a receiving space.

[0109] In some embodiments, the housing 11 further includes a frame, which includes a front support frame 116. The front support frame 116 is disposed between the front panel 111 and the rear panel 112, and the front panel 111 is fixedly connected to the front support frame 116. The front support frame 116 is used to support the front panel 111, the left side panel 113, the right side panel 114 and the top panel 115.

[0110] In some embodiments, the housing 11 includes a bottom plate 117, which is spaced apart from and parallel to the top plate 115. The bottom plate 117 is connected to the ends of the front plate 111, the rear plate 112, the left side plate 113, and the right side plate 114 away from the top plate 115.

[0111] In some embodiments, the frame includes a plurality of crossbeams 118, which are spaced apart and parallel to each other. One end of the plurality of crossbeams 118 is connected to the front plate 111 and the other end is connected to the rear plate 112. The plurality of crossbeams 118 are used to cooperate with the front support frame 116 to support the entire box 11, so that the entire box 11 can remain stable.

[0112] It is understandable that the width direction P1 of the box refers to the direction in which the left side panel 113 and the right side panel 114 are arranged alternately, the depth direction P2 refers to the direction in which the front panel 111 and the rear panel 112 are arranged alternately, and the height direction P3 refers to the height direction of the box 11 itself. The height direction P3 is perpendicular to both the width direction P1 and the depth direction P2.

[0113] In some embodiments, the front panel 111 is provided with two openings 111a, which are spaced apart along the width direction P1 of the housing 11.

[0114] The garment handling device 1 also includes two rollers 12, which are located in the aforementioned receiving space and connected to the housing 11. The two rollers 12 can be arranged side by side along the width direction P1 of the housing 11, and each roller 12 has an opening 121. The opening 121 is the garment insertion port, through which the user can insert garments into the roller 12 or remove garments from the roller 12. The two openings 121 are correspondingly connected to two openings 111a.

[0115] It is understood that the two rollers 12 can refer to two inner cylinders or two outer cylinders, or to two cylinder modules that simultaneously include inner and outer cylinders. In the following description, roller 12 is used as an example of an outer cylinder, but it is not intended that the following content applies only to this example. In addition, roller 12 can also be referred to as a cylinder body, and this application does not distinguish between "roller" and "cylinder body".

[0116] In some embodiments, the water inlet assembly 13 is located within the aforementioned receiving space. The water inlet assembly 13 includes a first water inlet pipe 131 and a second water inlet pipe 132. Both the first water inlet pipe 131 and the second water inlet pipe 132 extend along the depth direction P2 of the housing 11. The first water inlet pipe 131 is used to connect a water source (not shown) to one of the rollers 12, allowing water from the water source to be introduced into one roller 12. The second water inlet pipe 132 is used to connect a water source to another roller 12, allowing water from the water source to be introduced into the other roller.

[0117] Corresponding to the first water inlet pipe 131 and the second water inlet pipe 132, the two rollers 12 can be divided into the first roller 122 and the second roller 123. The first roller 122 is connected to the first water inlet pipe 131, and the second roller 123 is connected to the second water inlet pipe 132.

[0118] In some embodiments, along the height direction P3 of the housing 11, the first water inlet pipe 131 and the second water inlet pipe 132 are located between the first roller 122 and the second roller 123 in the width direction P1 of the housing 11, and are located above the first roller 122 and the second roller 123 along the height direction P3 of the housing 11. For example, the projections of the first water inlet pipe 131 and the second water inlet pipe 132 in the height direction P3 of the housing 11 can be located between the axes of the first roller 122 and the second roller 123, wherein the cylindrical axis of the first roller 122 is O1-O1' and the cylindrical axis of the second roller 123 is O2-O2'.

[0119] In some embodiments, the detergent dispensing assembly 14 is located within the aforementioned receiving space. The detergent dispensing assembly 14 includes two detergent dispensing ports 140, a liquid storage box 141, and two connecting pipes 142. The liquid storage box 141 and the two connecting pipes 142 are disposed within the housing 11. The liquid storage box 141 is located between the two rollers 12 and is positioned above the two rollers 12 along the height direction P3 of the housing 11. The liquid storage box 141 has a first inlet 141a, which is connected to both connecting pipes 142. The two connecting pipes 142 are connected to the two detergent dispensing ports 140 respectively, thus connecting the liquid storage box 141 to both detergent dispensing ports 140. In this way, when a user dispenses detergent into either of the two detergent dispensing ports 140, the detergent will enter the liquid storage box 141.

[0120] In some embodiments, the liquid storage box 141 is disposed between the first roller 122 and the second roller 123, and is located below both the first roller 122 and the second roller 123 in the height direction P3 of the box body 11.

[0121] In some embodiments, the detergent dispensing assembly 14 further includes a one-way connector 143, which is located between the first water inlet pipe 131 and the second water inlet pipe 132. The one-way connector 143 connects the liquid storage box 141, the first water inlet pipe 131 and the second water inlet pipe 132, and the detergent in the liquid storage box 141 can be delivered to the first water inlet pipe 131 and the second water inlet pipe 132 through the one-way connector 143.

[0122] It is understood that the one-way connector 143 is a connector component that ensures that detergent, after entering, can only enter the first water inlet pipe 131 and the second water inlet pipe 132 under the action of the water flow in the first water inlet pipe 131 and the second water inlet pipe 132, and cannot re-flow into the one-way connector 143 along with the water flow in the first water inlet pipe 131 and the second water inlet pipe 132.

[0123] In some embodiments, the one-way connector 143 has a second inlet 143a, a first outlet 143b, and a second outlet 143c. The second inlet 143a is connected to the liquid storage box 141, the first outlet 143b is connected to the first water inlet pipe 131, and the second outlet 143c is connected to the second water inlet pipe 132.

[0124] The detergent dispensing assembly 14 also includes a dispensing pump 144, which is used to pump detergent from the reservoir 141 into the one-way connector 143.

[0125] In some embodiments, in the depth direction P2 of the housing 11, the distance between the liquid reservoir 141 and the front panel 111 is less than the distance between the liquid reservoir 141 and the rear panel 112. The distance between the one-way connector 143 and the front panel 111 is less than the distance between the one-way connector 143 and the rear panel 112. That is, the liquid reservoir 141 and the one-way connector 143 are generally closer to the front side of the housing 11.

[0126] By connecting the liquid storage box 141 to the one-way pipe connector 143, and then connecting the one-way pipe connector 143 to the first water inlet pipe 131 and the second water inlet pipe 132 respectively, the detergent in the liquid storage box 141 can enter the first drum 122 through the first water inlet pipe 131, and can also enter the second drum 123 through the second water inlet pipe 132. In other words, by setting up one liquid storage box 141, detergent can be added to both drums 12, which can reduce the number of internal components of the clothes handling device 1, thereby optimizing the pipe layout, improving the integration of the clothes handling device 1, and thus reducing the overall size of the clothes handling device 1. Furthermore, since the liquid storage box 141 is located below the space between the two rollers 12, and the first water inlet pipe 131, the second water inlet pipe 132, and the one-way connector 143 are all located above the space between the two rollers 12, and the liquid storage box 141 and the one-way connector 143 are positioned close to the front plate 111 in the depth direction P2 of the housing 11, the space between the two rollers 12 can be effectively utilized, making the internal structure of the garment handling device 1 more compact. This also reduces the length of the two connecting pipes 142, facilitating the rapid flow of detergent from the detergent dispensing port 140 into the liquid storage box 141. Simultaneously, the reduced length of the two connecting pipes 142 reduces detergent loss caused by adhering to the inner wall of the connecting pipes 142. Additionally, the distance between the liquid storage box 141 and the one-way connector 143 can be shortened, thereby reducing the pipe length between them and further reducing detergent delivery losses and the load on the dispensing pump 144.

[0127] Understandably, when the first water inlet pipe 131 and the second water inlet pipe 132 are in the water inlet state, the speed of the water flow is greater than the speed of the fluid inside the one-way pipe joint 143, so that the pressure inside the first water inlet pipe 131 and the second water inlet pipe 132 is less than the pressure inside the one-way pipe joint 143. In this way, the detergent inside the one-way pipe joint 143 can be drawn into the first water inlet pipe 131 and the second water inlet pipe 132 by utilizing the pressure difference, so that the detergent enters the first drum 122 and the second drum 123 along with the water inside the first water inlet pipe 131 and the second water inlet pipe 132 respectively.

[0128] In some embodiments, the height of the first liquid inlet 141a in the height direction P3 of the housing 11 is less than that of the two detergent dispensing ports 140, so that the detergent dispensed through the two detergent dispensing ports 140 can automatically flow into the liquid storage box 141 under the action of gravity.

[0129] In some embodiments, such as Figure 5 and Figure 6 As shown, the orthographic projection of the one-way connector 143 on the height direction P3 of the housing 11 lies between the axes of the two rollers 12. On the height direction P3 of the housing 11, the liquid storage box 141 is located below the two rollers 12, while the one-way connector 143 is located above the two rollers 12. The rollers 12 are generally cylindrical. When the two rollers 12 are radially spaced apart, i.e., spaced apart along the width direction P2 of the housing 11, the space above and below the two rollers 12 is relatively large, which can be used to place other components. When the orthographic projection of the one-way connector 143 on the height direction P3 of the housing lies between the axes of the two rollers 12, the one-way connector 143 is positioned in the space between the two rollers 12. Simultaneously, on the height direction P3 of the housing 11, the liquid storage box 141 is located below the two rollers 12, while the one-way connector 143 is located above the two rollers 12. In this way, the space inside the box 11 between the two rollers 12 can be effectively utilized, the internal compactness of the garment processing device 1 can be improved, the volume of the garment processing device 1 can be reduced, and the miniaturization design of the garment processing device 1 can be achieved.

[0130] In some embodiments, such as Figure 4 and Figure 5 As shown, the two connecting pipes 142 are respectively connected to the liquid storage box 141. In some other embodiments, such as Figure 8 As shown, Figure 8This is a front view of the internal structure of the clothing processing device with a collection section in an embodiment of this application. Two connecting pipes 142 are connected to the liquid storage box 141 through the same collection pipe 145. That is, the two connecting pipes 142 are connected to the first liquid inlet 141a through the collection pipe 145. For example, the collection pipe 145 includes opposing collection inlets (not shown) and collection outlets (not shown). The collection inlets are connected to the two connecting pipes 142, and the collection outlets are connected to the first liquid inlet 141a.

[0131] Please see also Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of the internal structure of the garment processing device with a feeding box in an embodiment of this application. Figure 10 yes Figure 5 A cross-sectional view along the A-A' direction.

[0132] In some embodiments, the detergent dispensing assembly 14 further includes two dispensing boxes 146, which are disposed corresponding to two detergent dispensing ports 140 and connected to the front panel 111. The two dispensing boxes 146 are also connected to two connecting pipes 142 respectively. The detergent dispensed through the two detergent dispensing ports 140 enters the two connecting pipes 142 via the two dispensing boxes 146, and finally enters the liquid storage box 141 via the manifold 145.

[0133] In some embodiments, the cross-sectional profiles of the two detergent dispensing ports 140 in the width direction P1 of the housing 11 match the cross-sectional profiles of the two dispensing boxes 146 in the width direction P1 of the housing 11. Furthermore, the area of ​​the cross-sectional profiles of the two dispensing boxes 146 in the width direction P1 of the housing 11 is greater than the area of ​​the cross-sectional profiles of the two connecting pipes 142 in the width direction P1 of the housing 11. That is, the two detergent dispensing ports 140 are set to be larger, making it easier for users to dispense detergent through the detergent dispensing ports 140.

[0134] Optionally, the two detergent dispensing ports 140 can be generally rectangular or elliptical, with the long side or major axis of the detergent dispensing port 140 extending along the width direction P1 of the housing 11. Correspondingly, the space enclosed by the two dispensing boxes 146 is generally rectangular or elliptical.

[0135] In some embodiments, the front panel 111 is provided with a first connecting portion 111c on each edge surrounding the two detergent dispensing ports 140. The two first connecting portions 111c are respectively inserted into the corresponding dispensing boxes 146 and fixedly connected to them. Thus, when a user dispenses detergent into the dispensing boxes 146 through the detergent dispensing ports 140, the detergent, flowing downwards under gravity, will not flow along the gap between the first connecting portions 111c and the dispensing boxes 146 to the outside of the dispensing path. It can be understood that the two detergent dispensing ports 140, the two dispensing boxes 146, the two connecting pipes 142, the manifold 145, the liquid storage box 141, and the one-way connector 143 together constitute the dispensing path.

[0136] In some embodiments, the first connecting part 111c and the feeding box 146 are interference-fitted to achieve a seal between the first connecting part 111c and the feeding box 146. Of course, a waterproof seal can also be achieved between the first connecting part 111c and the feeding box 146 through structures such as rubber rings, silicone rings, and sealant.

[0137] In other embodiments, the first connecting part 111c and the feeding box 146 can also be connected to each other by means of snap-fit, screw-fit, bonding, ultrasonic welding, etc.

[0138] See you again Figure 9 and Figure 10 In some embodiments, the detergent dispensing assembly 14 further includes a dispensing pipe 147, and a dispensing pump 144 is disposed above and connected to the liquid storage box 141. One end of the dispensing pipe 147 is connected to the dispensing pump 144, and the other end is connected to a one-way connector 143. The dispensing pump 144 can pump the detergent in the liquid storage box 141 into the one-way connector 143.

[0139] Please see also Figures 11 to 13 , Figure 11 This is a schematic diagram showing the position of the one-way pipe connector relative to the front panel in an embodiment of this application. Figure 12 yes Figure 11 The diagram shown is a right view of the garment handling device. Figure 13 yes Figure 11 A cross-sectional view along the B-B' direction.

[0140] In some embodiments, the distance between the side of the liquid storage box 141 near the front plate 111 and the front plate 111 is L1, and the distance between the end of the one-way connector 143 near the front plate 111 and the front plate 111 is L2, and L1 and L2 satisfy the relationship: 1.2L1≤L2≤7.5L1. By appropriately setting the ratio of the distance L1 between the liquid storage box 141 and the front plate 111 to the distance L2 between the one-way connector 143 and the front plate 111, the distance between the liquid storage box 141 and the one-way connector 143 can be avoided from being too large, thereby reasonably limiting the length of the pipe between the liquid storage box 141 and the one-way connector 143, and reducing the difficulty of laying the pipes in the housing 11. In addition, since the detergent will adhere to the inner wall of the delivery pipe during the delivery process before mixing with water, resulting in a certain loss of detergent, shortening the length of the pipe between the liquid storage box 141 and the one-way connector 143 can also reduce the loss of detergent caused by the excessively long delivery path in the delivery pipe. When L2 < 1.2L1, the distance between the one-way connector 143 and the front plate 111 is too small. The pipe connecting the reservoir 141 and the one-way connector 143 is prone to interference with the front plate 111 after bending at the one-way connector 143. This causes the pipe to be squeezed by the front plate 111, affecting its normal transport function and making it prone to fatigue due to long-term pressure, thus leading to pipe damage. When L2 > 7.5L1, the distance between the one-way connector 143 and the front plate 111 is too large. This results in an excessively large distance between the reservoir 141 and the one-way connector 143. Therefore, the length of the pipe connecting the reservoir 141 and the one-way connector 143 must be increased, increasing detergent transport loss and the workload of the dispensing pump 144.

[0141] It is understandable that, since the outer side of the front panel 111, that is, the side of the front panel 111 facing away from the inside of the housing 11, is usually flat, the distance between the liquid storage box 141 and the one-way pipe connector 143 and the front panel 111 can be referenced by the outer side of the front panel 111.

[0142] In some embodiments, the value of L1 ranges from 20mm to 50mm. When L1 ranges from 20mm to 30mm, the distance between the liquid storage box 141 and the front panel 111 is small, resulting in a high degree of compactness, which is beneficial for the miniaturization design of the garment handling device 1. When L1 ranges from 30mm to 40mm, the distance between the liquid storage box 141 and the front panel 111 is appropriately increased, making it easier for the pipe between the liquid storage box 141 and the one-way pipe connector 143 to avoid other components on the front panel 111, such as door locks. When L1 ranges from 40mm to 50mm, the distance between the liquid storage box 141 and the front panel 111 is large, making it easier to lay a connecting pipe 142 between the front panel 111 and the liquid storage box 141, so that the connecting pipe 142 connects the detergent dispensing port 140 and the liquid storage box 141. When L1 is less than 20mm, the distance between the reservoir and the front panel is small, making it inconvenient to install a connecting pipe, or requiring a reduction in the pipe diameter. This reduces detergent delivery efficiency and makes the detergent susceptible to pressure fluctuations within the reservoir, hindering its flow. Even with the one-way connector positioned close to the reservoir, the dispensing pump struggles to deliver detergent to the connector. When L1 is greater than 50mm, the distance between the reservoir and the front panel is large, necessitating a longer connecting pipe. This results in a longer detergent flow path and increased delivery losses. Even with the one-way connector positioned close to the reservoir, detergent delivery losses remain high.

[0143] In some embodiments, the value of L2 ranges from 60mm to 150mm. When the value of L2 is between 60mm and 90mm, the distance between the one-way connector 143 and the front plate 111 is small, shortening the pipe length between the liquid storage box 141 and the one-way connector 143, which helps reduce detergent delivery loss and facilitates the miniaturization design of the garment handling device 1. When the value of L2 is between 90mm and 120mm, appropriately increasing the distance between the one-way connector 143 and the front plate 111 creates sufficient space to accommodate the portions of the first water inlet pipe 131 and the second water inlet pipe 132 located between the one-way connector 143 and the front plate 111. When the value of L2 is between 120mm and 150mm, the distance between the one-way connector 143 and the front plate 111 is large, allowing for more flexible placement of the water inlet pipes and providing space for further optimization of the pipe layout. When L2 is less than 60mm, the pipe connected to the one-way connector 143 is easily squeezed by the front plate, which is not conducive to the delivery of detergent and is also easy to damage the pipe. When L2 is greater than 150mm, the distance between the one-way connector 143 and the front plate is too large, which will result in an excessively long pipe length between the dispensing pump 144 and the one-way connector 143, leading to increased detergent delivery loss and increased workload of the dispensing pump 144.

[0144] Please see also Figures 14 to 19 , Figure 14This is a schematic diagram of the connection between the one-way pipe connector and the water inlet pipe in an embodiment of this application. Figure 15 yes Figure 14 The diagram shows the assembly of the inlet pipe with the plug portion and the one-way pipe connector. Figure 16 This is a cross-sectional schematic diagram of the one-way pipe connector in the embodiments of this application. Figure 17 yes Figure 15 A diagram of the right view. Figure 18 yes Figure 17 A cross-sectional view along the C-C' direction. Figure 19 yes Figure 18 Enlarged schematic diagram of region B in the middle.

[0145] In some embodiments, the one-way connector 143 includes an inlet section 143d, a first dispensing section 143e, and a second dispensing section 143f. The inlet section 143d is connected to the first dispensing section 143e and the second dispensing section 143f simultaneously. The first dispensing section 143e is connected to the first water inlet pipe 131, and the second dispensing section 143f is connected to the second water inlet pipe 132. The detergent in the one-way connector 143 can enter the first water inlet pipe 131 through the first dispensing section 143e, and the detergent in the one-way connector 143 can enter the second water inlet pipe 132 through the second dispensing section 143f.

[0146] Specifically, the inlet section 143d has two opposite ends, one end having the aforementioned second inlet 143a and the other end having a third outlet 143g. The first distribution section 143e has a first distribution port 143h at one end, which is connected to the third outlet 143g, and a first outlet 143b at the other end, which is connected to the first water inlet pipe 131. The second distribution section 143f has a second distribution port 143i at one end, which is connected to the third outlet 143g, and a second outlet 143c at the other end, which is connected to the second water inlet pipe 132.

[0147] Since the first inlet pipe 131 and the second inlet pipe 132 extract detergent by creating a pressure difference between the water flow inside themselves and the one-way pipe joint 143, when the lengths of the first dispensing section 143e and the second dispensing section 143f are too large, the pressure has too little effect on the detergent, making it impossible to effectively extract the detergent. When the axial lengths of the first dispensing section 143e and the second dispensing section 143f differ significantly, it may result in one of the first inlet pipe 131 and the second inlet pipe 132 being able to extract detergent normally, while the other cannot extract detergent or can only extract a small amount of detergent. Therefore, in some embodiments, the axial length of the first dispensing section 143e is equal to the axial length of the second dispensing section 143f. This reduces the conveying loss of detergent along different paths, thereby reducing factors affecting the amount of detergent dispensed in different drums 12 and helping to achieve precise quantitative dispensing of detergent.

[0148] Understandably, the one-way connector 143 can be a tee structure, which can be T-shaped or Y-shaped. When the one-way connector 143 is T-shaped, the axial direction of the first dispensing section 143e and the second dispensing section 143f can be along the width direction P1 of the tank 11. When the one-way connector 143 is Y-shaped, the axial direction of the first dispensing section 143e and the second dispensing section 143f forms an angle with the depth direction P2 of the tank 11. For example, the axial direction of the first dispensing section 143e can be biased towards the first inlet pipe 131 and form a 45° angle with the depth direction P2 of the tank 11, while the axial direction of the dispensing section 143f can be biased towards the second inlet pipe 132 and form a 45° angle with the depth direction P2 of the tank 11. Of course, the axial directions of the first dispensing section 143e and the second dispensing section 143f can also form other angles with the depth direction P2 of the tank 11, which will not be elaborated here.

[0149] In some embodiments, the portion of the first dispensing section 143e near the first water inlet pipe 131 is radially recessed and extends in the direction of detergent flow, thereby forming a duckbill valve. In this way, after the detergent flows out from the duckbill valve, it mixes with the water flow in the first water inlet pipe 131. Under the action of the duckbill valve, the water flow in the first water inlet pipe 131 cannot enter the interior of the first dispensing section 143e, and therefore cannot enter the storage box 141 through the one-way connector 143, thus preventing overflow from the storage box 141.

[0150] Similarly, the portion of the second dispensing section 143f near the second inlet pipe 132 can also be radially recessed and extended along the direction of detergent flow, thus forming a duckbill valve. The duckbill valve of the second dispensing section 143f can also prevent water from flowing from the second inlet pipe 132 into the storage box 141 through the second dispensing section 143f, thereby preventing water from overflowing from the storage box 141.

[0151] It is understandable that the first liquid outlet 143b and the second liquid outlet 143c constitute the duckbill valve outlet of the first liquid distribution section 143e and the duckbill valve outlet of the second liquid distribution section 143f, respectively.

[0152] In some embodiments, the one-way connector 143 may further include a liquid-containing section 143j, which has a liquid-containing chamber 143k for containing detergent. A third outlet 143g is connected to the liquid-containing section 143j and communicates with the liquid-containing chamber 143k. Both the first dispensing outlet 143h and the second dispensing outlet 143i are connected to the liquid-containing section 143j and communicate with the liquid-containing chamber 143k. The detergent pumped into the one-way connector 143 by the dispensing pump 144 can be temporarily stored in the liquid-containing chamber 143k.

[0153] In some embodiments, the first dispensing section 143e includes a first inner tube 143l and a first outer tube 143m. The first outer tube 143m surrounds the outer periphery of the first inner tube 143l, and a first installation gap 143m' is formed between the first inner tube 143l and the first outer tube 143m. The first installation gap 143m' extends around the edge of the first inner tube 143l, and the first inner tube 143l partially constitutes the aforementioned duckbill valve. The first water inlet pipe 131 includes a first main body 131a and a first insertion part 131b. One end of the first main body 131a is connected to the first roller 122, and the other end is connected to a water source. The first insertion part 131b is connected to and communicates with the first main body 131a in the middle part of the first main body 131a. The end of the first insertion part 131b away from the first main body 131a extends into the first installation gap 143m' and is connected to the first dispensing section 143e.

[0154] Understandably, the first inner tube 143l extends into the interior of the first connector 131b. Thus, during the assembly of the first dispensing section 143e and the first water inlet pipe 131, the first installation gap 143m serves to guide assembly and prevent mistaken insertion. Furthermore, when the first water inlet pipe 131 is in the water-inlet state, since the first connector 131b of the first water inlet pipe 131 is located within the space enclosed by the first inner tube 143l and the first outer tube 143m, leakage of water from the first water inlet pipe 131 through the first connector 131b can be reduced or prevented. Additionally, because the first inner tube 143l is inserted into the interior of the first connector 131b, when detergent flows from the first inner tube 143l into the first connector 131b, the detergent can avoid the joint between the first inner tube 143l and the first connector 131b, preventing leakage of detergent from the joint between the first inner tube 143l and the first connector 131b.

[0155] In some embodiments, a waterproof seal can be provided in the first installation gap 143m to improve the sealing effect at the connection between the first insertion part 131b and the first liquid distribution section 143e. For example, an O-ring, a silicone ring, waterproof adhesive, or waterproof tape can be used. In other embodiments, the first insertion part 131b can be configured with an interference fit with the first inner tube 143l and the first outer tube 143m to improve the sealing effect.

[0156] In some embodiments, the second dispensing section 143f can be configured with reference to the first dispensing section 143e, and the second inlet pipe 132 can be configured with reference to the first inlet pipe 131. For example, the second dispensing section 143f includes a second inner pipe 143n and a second outer pipe 143o. The second outer pipe 143o surrounds the outer periphery of the second inner pipe 143n, and a second installation gap 143o' is formed between the second inner pipe 143n and the second outer pipe 143o. The second installation gap 143o' extends around the edge of the second inner pipe 143n, and the second inner pipe 143n partially constitutes the aforementioned duckbill valve. The second water inlet pipe 132 includes a second main body 132a and a second insertion part 132b. One end of the second main body 132a is connected to the second roller 123, and the other end is connected to the water source. The second insertion part 132b is connected to and communicates with the second main body 132a in the middle part of the second main body 132a. The end of the second insertion part 132b away from the second main body 132a extends into the second installation gap 143o' and is connected to the second liquid distribution section 143f.

[0157] Similarly, the seal between the second water inlet pipe 132 and the second liquid distribution section 143f can be set with reference to the seal between the first water inlet pipe 131 and the first liquid distribution section 143e.

[0158] In some embodiments, the first main body 131a may include a first main body segment 131c, a first reduced diameter segment 131d, and a second main body segment 131e. The first reduced diameter segment 131d is connected to the other end of the first insertion part 131b. One end of the first main body segment 131c is connected to the first roller 122, and the other end of the first main body segment 131c is connected to the first reduced diameter segment 131d. One end of the second main body segment 131e is connected to the first reduced diameter segment 131d, and the other end of the second main body segment 131e is used to connect to a water source. The inner diameter of the first reduced diameter segment 131d is smaller than the inner diameter of the first main body segment 131c and the second main body segment 131e.

[0159] The inner diameter of the portion connecting the first main body 131a and the first insertion part 131b is set to be smaller than the inner diameters of both ends. When water flows through the first insertion part 131b, due to the Venturi effect, the flow velocity of the water in the first narrowing section 131d will be greater than the flow velocity of the water in the first main body section 131c and the second main body section 131e, thereby improving the mixing efficiency of detergent and water. In addition, because the flow velocity of the water in the first narrowing section 131d is greater and the pressure is lower, a greater pressure difference is formed with the interior of the first dispensing section 143e, which helps to draw out the detergent in the first dispensing section 143e and avoid detergent residue in the first dispensing section 143e that may cause blockage.

[0160] In some embodiments, the inner diameters of the first main body segment 131c and the second main body segment 131e are both D1, and the inner diameter of the first narrowed segment 131d is D2, with D1 and D2 satisfying the relationship: 0.3D1 < D2 < 0.7D1. This effectively reduces the inner diameter of the first narrowed segment 131d, significantly increasing the water flow velocity, while ensuring sufficient unit flow rate, thus avoiding low influent efficiency due to the small cross-sectional area of ​​the first narrowed segment 131d. When 0.3D1 > D2, the inner diameter of the first narrowing section 131d is too small, which will directly lead to a significant reduction in the flow area of ​​the first narrowing section 131d, resulting in a low water inlet efficiency of the first water inlet pipe 131. In addition, according to Poiseuille's law, due to the reduction in the inner diameter of the first narrowing section 131d, the flow velocity of the water in the first narrowing section 131d will increase significantly, which will increase the resistance experienced by the water flow in the first narrowing section 131d, which will also increase the water inlet load of the clothing processing device 1 to a certain extent. When D2 is greater than 0.7D1, the inner diameter of the first narrowing section 131d is smaller than that of the first main section 131c and the second main section 131e. As a result, the flow velocity of the water inside the first narrowing section 131d is not significantly increased compared to that inside the first main section 131c and the second main section 131e. The pressure difference between the first dispensing section 143e and the first narrowing section 131d is relatively small, which reduces the extraction efficiency of detergent in the first dispensing section 143e and fails to effectively improve the mixing efficiency of detergent and water.

[0161] In some other embodiments, the inner diameters of the first body segment 131c and the second body segment 131e may be different. For example, the inner diameter of the second body segment 131e may be D3, and D2 < D1, and / or, D2 < D3, and / or, D1 < D3.

[0162] In one example, D1, D2, and D3 satisfy the relation: D2 < D1 < D3.

[0163] In some embodiments, D1, D2, and D3 may also satisfy the following relationship: D2 < D1, and / or D2 < D3, and / or D3 < D1.

[0164] In one example, D1, D2, and D3 satisfy the relation: D2 < D3 < D1.

[0165] It is understandable that, for the part where the second main body 132a connects to the second insertion part 132b, the third main body segment 132c, the second diameter reduction segment 132d, and the fourth main body segment 132e can be arranged in sequence, referring to the arrangement of the first main body 131a. This will not be elaborated here.

[0166] Please see also Figures 20 to 24 , Figure 20 yes Figure 2 The diagram shown is a top view of the crossbeam. Figure 21 yes Figure 20 The diagram shows a right-side view of the beam. Figure 22 yes Figure 2 The diagram shows the three-dimensional structure of the beam. Figure 23 yes Figure 22 The diagram shows a right-side view of the beam. Figure 24 yes Figure 22 The diagram shows a front view of the beam.

[0167] In some embodiments, as described above, the housing 11 includes a rear plate 112 and a crossbeam 118. The rear plate 112 is spaced apart from the front plate 111 along the depth direction P2 of the housing 11. The crossbeam 118 connects the upper parts of the front plate 111 and the rear plate 112 along the height direction P3 of the housing 11. The projection of the crossbeam 118 in the height direction P3 of the housing 11 is located between the axes of the two rollers 12. The first water inlet pipe 131 and the second water inlet pipe 132 are located on opposite sides of the crossbeam 118 along the width direction P1 of the housing 11. The crossbeam 118 is used to fixably connect the front plate 111 and the rear plate 112 to fixably support the housing 11, so that the shape of the housing 11 remains stable.

[0168] Understandably, the two rollers 12 are located between the front plate 111 and the rear plate 112, and in the height direction P3 of the housing 11, the two rollers 12 are also located below the crossbeam 118.

[0169] In some embodiments, the top plate 114 can serve as a cover plate, covering the crossbeam 118 along the height direction P3 of the housing 11, and the crossbeam 118 can also be used to support the top plate 114.

[0170] In some embodiments, the crossbeam 118 includes a front section 118a and a rear section 118b, which are sequentially arranged and connected along the depth direction P2 of the housing 11. Specifically, one end of the front section 118a is connected to the front plate 111, and the other end extends toward the rear plate 112. One end of the rear section 118b is connected to the other end of the front section 118a, and the other end of the rear section 118b extends toward the rear plate 112 and is fixedly connected to the rear plate 112.

[0171] In some embodiments, in the height direction P3 of the housing 11, the upper surface 118a' of the front section 118a is located below the upper surface 118b' of the rear section 118b, that is, the height of the upper surface 118a' of the front section 118a is less than the height of the upper surface 118b' of the rear section 118b. Furthermore, the one-way pipe connector 143 is disposed on the upper surface 118a' of the front section 118a and overlaps with the upper surface 118a' of the front section 118a, while portions of both the first water inlet pipe 131 and the second water inlet pipe 132 are located below the rear section 118b and overlap with the upper surface 118b' of the rear section. By positioning the upper surface 118a' of the front section 118a of the crossbeam 118 below the upper surface 118b' of the rear section 118b, the front section 118a of the crossbeam 118 creates space for the one-way pipe connector 143. The one-way pipe connector 143 is then attached to the upper surface 118a' of the front section 118a, which also provides support, ensuring the stability of the detergent dispensing assembly 14. Furthermore, the first inlet pipe 131 and the second inlet pipe 132 are also attached to the rear section 118b of the crossbeam 118. The crossbeam 118 secures the first inlet pipe 131 and the second inlet pipe 132, ensuring the stability of the pipes.

[0172] It is understandable that "parts of the first water inlet pipe 131 and the second water inlet pipe 132 are located below the rear section 118b" means that the first water inlet pipe 131 and the second water inlet pipe 132 are located below the rear upper surface 118b' of the rear section 118b in the height direction P3 of the housing 11. In this way, the rear upper surface 118b' of the rear section 118b can properly abut against the top plate 114 and support the top plate 114. Furthermore, when the first main body 131a is provided with the first main body section 131c, the first reduced diameter section 131d, and the second main body section 131e, and the second main body 132a is provided with the third main body section 132c, the second reduced diameter section 132d, and the fourth main body section 132e, the second main body section 131e and the fourth main body section 132e are located below the rear upper surface 117b' of the rear section 118b'.

[0173] Since the water flow in the first inlet pipe 131 and the second inlet pipe 132 needs to first extract the detergent from the one-way connector 143 before delivering the detergent to the first drum 122 and the second drum 123 respectively, both the first inlet pipe 131 and the second inlet pipe 132 have portions that, after connecting to the one-way connector 143, continue to extend along the depth direction P2 of the housing 11 towards the front panel 111, and then bend and extend along the width direction P1 of the housing 11 towards the first drum 122 and the second drum 123 respectively, and connect to the first drum 122 and the second drum 123 respectively. Therefore, the portions of the first water inlet pipe 131 and the second water inlet pipe 132 between the one-way pipe joint 143 and the front plate 111 can be fixed to the front section 118a of the crossbeam 118 to further support the first water inlet pipe 131 and the second water inlet pipe 132, improve the stability of the first water inlet pipe 131 and the second water inlet pipe 132, and prevent the first water inlet pipe 131 and the second water inlet pipe 132 from being damaged by vibration when the garment processing device 1 performs the dehydration process.

[0174] It is understandable that when the first water inlet pipe 131 includes the first main body section 131c and the second water inlet pipe 132 includes the third main body section 132c, the first main body section 131c and the third main body section 132c are fixed to the front end 113a.

[0175] In some embodiments, the water inlet assembly 13 further includes a first water inlet valve 133 and a second water inlet valve 134, which are disposed on the rear plate 112 for connection to a water source. The end of the first water inlet pipe 131 away from the one-way connector 143 is connected to the first water inlet valve 133, and the end of the second water inlet pipe 132 away from the one-way connector 143 is connected to the second water inlet valve 134. To effectively utilize the internal space of the housing 11, the first water inlet valve 133 and the second water inlet valve 134 are disposed below the crossbeam 118. In this case, a portion of both the first water inlet pipe 131 and the second water inlet pipe 132 is bent downwards below the crossbeam 118 before being connected to the first water inlet valve 133 and the second water inlet valve 134, respectively. Thus, when the user only needs to use one drum 12 for washing, they only need to open the inlet valve of the water inlet pipe corresponding to that drum 12 to allow water to enter through that pipe. The water flow in that pipe is used to extract the detergent. Since there is no water flow in the other inlet pipe, the detergent will not be extracted into it. For example, when the user only uses the first drum 122, the first inlet valve 133 is opened, creating a water flow in the first inlet pipe 131. Under the action of this water flow, the detergent is extracted through the first dispensing section 143e into the first inlet pipe 131 and mixes with the water. The second inlet valve 134 remains closed, and since there is no water flow in the second inlet pipe 132, the detergent in the one-way connector 143 cannot be extracted through the second dispensing section 143f into the second inlet pipe 132.

[0176] The second aspect of this application also provides a combined garment processing device 2, such as... Figure 25 As shown, Figure 25 This is a perspective structural diagram of a combined clothing processing device 2 according to an embodiment of this application. The combined clothing processing device 2 includes a first clothing processing device 21 and a second clothing processing device 22, with the second clothing processing device 22 detachably disposed above the first clothing processing device 21. The first clothing processing device 21 is a drum washing machine, and the second clothing processing device 22 is the clothing processing device 1 of any embodiment in the first aspect.

[0177] Understandably, the first garment handling device 21 can be a single-tub washing machine or a multi-tub washing machine.

[0178] In some embodiments, the dimensions of the first garment processing device 21 and the second garment processing device 22 in the width direction P1 are equal or substantially equal, or the dimensions of the first garment processing device 21 and the second garment processing device 22 in the width direction P1 differ by no more than 20 mm.

[0179] By detachably stacking the first garment processing device 21 and the second garment processing device 22, users can choose to purchase and use only one first garment processing device 21, or only one second garment processing device 22, or a combined garment processing device 2 composed of the first garment processing device 21 and the second garment processing device 22, according to their actual needs, such as the size of the installation space, the number of family members, or whether there are young children. In other words, the combined garment processing device 2 provided by this application can provide users with a wider variety of choices.

[0180] In some embodiments, the combined garment processing device 2 further includes a connecting bracket 23, which is disposed between the first garment processing device 21 and the second garment processing device 22, and the first garment processing device 21 and the second garment processing device 22 are detachably connected through the connecting bracket 23.

Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the idea of ​​this utility model. There may be changes in the specific implementation and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
