Description
Technical Field
[0001] This application relates to the field of washing machine technology, and more particularly to a drum washing machine. Background Technology
[0002] In modern life, washing machines have become an essential household appliance. Washing machines include top-loading washing machines and front-loading washing machines. Front-loading washing machines are generally front-opening. The front of the washing machine has a loading port and a door. The door is hinged to the washing machine via a hinge assembly to open or close the loading port.
[0003] However, after prolonged operation, the hinge components of current drum washing machines may experience wear, dirt buildup, and material aging. These problems can lead to increased hinge damping, making the door less smooth to open and close, and consequently making it difficult to open and close the door. Utility Model Content
[0004] This application discloses a drum washing machine that reduces the difficulty for users when opening and closing the drum washing machine door.
[0005] To achieve the above objectives, embodiments of this application disclose a drum washing machine, comprising:
[0006] The box has a receiving cavity inside and a garment inlet connected to the receiving cavity on the box.
[0007] A washing tub, wherein the washing tub is disposed within the receiving cavity, and the opening of the washing tub is correspondingly disposed to the loading port;
[0008] The door body includes:
[0009] The door body has a hinged end and a rotating end distributed in a horizontal direction. The hinged end is hinged to the box body to open or close the garment opening. The door body is provided with an observation port that extends through the door body along its thickness direction.
[0010] An observation window, one end of which is located inside the observation opening and seals the observation opening, and the other end of which protrudes from the observation opening toward the rear side of the door body;
[0011] The door body has a first edge located at the hinge end and a second edge located at the rotating end. The maximum horizontal distance between the axis of the observation port and the first edge is L1, and the maximum horizontal distance between the axis of the observation port and the second edge is L2, where L1 is less than L2.
[0012] In this application, the door body includes a door body and an observation window. The door body is provided with an observation opening. One end of the observation window is located inside the observation opening and seals the observation opening. The other end protrudes from the observation opening along the rear side of the door body. The door body has a hinge end that is hinged to the housing and a rotating end that rotates around the hinge end. The door body also has a first edge located at the hinge end and a second edge located at the rotating end.
[0013] The maximum horizontal distance between the axis of the observation port and the first edge is L1, and the maximum horizontal distance between the axis of the observation port and the second edge is L2. L1 is less than L2, which means that the second edge is farther from the axis of the observation port than the first edge. Compared with the technical solution where the distances between the second edge and the first edge and the axis of the observation port are the same, the second edge of this application is farther from the hinge axis between the door body and the box. Thus, the lever arm when the user moves the second edge of the door to open the door is larger, which can better overcome the damping applied by the hinge when opening the door, making the door smoother during opening and closing, and thus making it easier to open and close the door.
[0014] In one alternative embodiment, (L2 / L1) = 1.1 to 1.3.
[0015] If (L2 / L1) is less than 1.1, although the second edge is farther from the axis of the observation port than the first edge, it can solve the technical problem to some extent. However, when (L2 / L1) is less than 1.1, the distance between the second edge and the hinge axis is not large enough, which will weaken the effect of making it easier for users to open and close the door. If (L2 / L1) is greater than 1.3, the distance between the second edge and the hinge axis will be too large, resulting in the door occupying too much lateral space, which will increase the lateral size of the drum washing machine.
[0016] In one alternative embodiment, L1 = 110-150 mm, L2 = 125-170 mm.
[0017] If L1 is less than 110mm and L2 is less than 125mm, the increase in distance between the second edge and the hinge axis is small, which weakens the effect of making it easier for users to open and close the door; if L1 is greater than 150mm and L2 is greater than 170mm, the distance between the second edge 215 and the hinge axis will be too large, causing the door 200 to occupy too much lateral space, which will increase the lateral size of the drum washing machine.
[0018] Therefore, in this embodiment, L1 is controlled at 110-150mm and L2 is controlled at 125-170mm, so that the distance between the second edge and the hinge axis is within a suitable range. This not only enhances the effect of making it easier for users to open and close the door, but also prevents the door from occupying too much horizontal space and increasing the horizontal size of the drum washing machine.
[0019] In one optional embodiment, the first edge is arc-shaped and protrudes in a direction away from the rotating end, the first edge is concentrically arranged with the observation port, and the second edge extends in a vertical direction.
[0020] In this embodiment, the arc-shaped first edge is located at the hinge end, and the first edge protrudes in the direction away from the rotating end. The arc-shaped first edge is less likely to interfere with other components during the rotation of the door. The second edge extends in the vertical direction, so any position on the second edge is far away from the hinge axis. The user can easily overcome the damping of the hinge by moving any position on the second edge to open and close the door without having to deliberately move a specific position on the second edge, which simplifies the opening and closing operation.
[0021] In an optional embodiment, the door body further has a third edge and a fourth edge spaced apart in a vertical direction, both the third edge and the fourth edge extending in the horizontal direction, with the third edge located above the fourth edge;
[0022] One end of the third edge is connected to the upper end of the first edge, and the other end of the third edge is connected to the upper end of the second edge; one end of the fourth edge is connected to the lower end of the first edge, and the other end of the fourth edge is connected to the lower end of the second edge.
[0023] In this embodiment, the hinge end is formed by the first edge, and the rotating end is formed by the second, third, and fourth edges. Since the third and fourth edges are parallel and the second edge extends vertically, the rotating end formed by the second, third, and fourth edges is rectangular. Compared to the arc-shaped rotating end, the rectangular rotating end has a larger area, so more components can be arranged on the rotating end, or the size of the components arranged on the rotating end can be increased, such as a door handle, which can improve the user's operating convenience.
[0024] In one optional embodiment, the radius of the first edge is 115-130 mm, the length of the third edge is equal to that of the fourth edge, and the length of the third edge is 260-300 mm.
[0025] If the radius of the first edge is less than 115mm and the length of the third edge is less than 260mm, the increase in distance between the second edge and the hinge axis is small, which weakens the effect of making it easier for users to open and close the door. If the radius of the first edge is greater than 130mm and the length of the third edge is greater than 300mm, the distance between the second edge and the hinge axis will be too large, causing the door to occupy too much lateral space, which will increase the lateral size of the drum washing machine.
[0026] Therefore, in this embodiment, the radius of the first edge is controlled at 115-130mm and the length of the third edge is controlled at 260-300mm. This allows the distance between the second edge and the hinge axis to be within a suitable range, which not only enhances the effect of making it easier for users to open and close the door, but also prevents the door from occupying too much horizontal space and increasing the horizontal size of the drum washing machine.
[0027] In one optional embodiment, the washing tub includes:
[0028] A first cylindrical body is disposed within the receiving cavity;
[0029] The second cylindrical body is disposed within the receiving cavity and is arranged side by side with the first cylindrical body in the horizontal direction;
[0030] The garment inlet includes:
[0031] The first garment inlet is provided corresponding to the opening of the first cylinder;
[0032] The second garment inlet is provided corresponding to the opening of the second cylinder;
[0033] The number of doors includes two, each of which is rotatably connected to the box body, and the two doors respectively cooperate with the first garment inlet and the second garment inlet.
[0034] In this embodiment, the washing drum includes a first drum and a second drum that are spaced apart in the horizontal direction. The first drum and the second drum are two completely independent drums and are not connected. Therefore, the first drum and the second drum can operate independently to achieve zone washing. Zone washing can separate clothes with different washing requirements. For example, underwear and other intimate clothing and outerwear need to be washed separately to avoid cross-contamination and ensure the washing quality of the clothes.
[0035] In one optional embodiment, the front side of the box is provided with a first sub-slot and a second sub-slot that are connected in a horizontal direction, the first garment inlet is located on the bottom wall of the first sub-slot, and the second garment inlet is located on the bottom wall of the second sub-slot.
[0036] When both doors are closed, one of the doors is accommodated in the first sub-slot and the other is accommodated in the second sub-slot, and at least one of the doors is partially located at the connection between the first sub-slot and the second sub-slot.
[0037] In this embodiment, the first sub-slot and the second sub-slot are connected. Therefore, there is no solid material between the first sub-slot and the second sub-slot. When both doors are closed, at least one of the two doors is located at the connection between the first sub-slot and the second sub-slot. In other words, this embodiment uses the space of the solid material in the previous embodiment to accommodate the door, which can reduce the lateral space occupied by the door in the cabinet, thereby reducing the lateral size of the drum washing machine.
[0038] In one alternative embodiment, the first sub-slot and the second sub-slot together form a receiving groove, the shape of which is racetrack-shaped.
[0039] In this embodiment, the racetrack-shaped receiving groove 120 has a first arc surface and a second arc surface distributed in the horizontal direction, and a first plane and a second plane distributed in the vertical direction. The two ends of the first plane are tangent to the upper ends of the first arc surface and the upper ends of the second arc surface, respectively. The two ends of the second plane are tangent to the lower ends of the first arc surface and the lower ends of the second arc surface, respectively. It can be seen that there is no non-smooth transition area on the inner wall of the racetrack-shaped receiving groove, which can avoid generating large stress on the inner wall of the receiving groove, thereby extending the service life of the box.
[0040] In one optional embodiment, when both doors are in the closed state, the rotating ends of the two doors are the ends of the two doors that are close to each other, and the gap between the rotating ends of the two doors is less than 3mm.
[0041] In this embodiment, when both doors are closed, the gap between the rotating ends of the two doors is less than 3mm. This allows the two doors to be spaced apart by a smaller distance, thereby reducing the lateral space occupied by the doors in the cabinet and thus reducing the lateral dimensions of the drum washing machine.

[0050] 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.

Unless otherwise stated, "a plurality of" means two or more.
[0055] In modern life, washing machines have become an essential household appliance. Washing machines include top-loading washing machines and front-loading washing machines. Front-loading washing machines are generally front-opening. The front of the washing machine has a loading port and a door. The door is hinged to the washing machine via a hinge assembly to open or close the loading port.
[0056] However, after prolonged operation, the hinge components of current drum washing machines may experience wear, dirt buildup, and material aging. These problems can lead to increased hinge damping, making the door less smooth during opening and closing.
[0057] Currently, when users open the door of a front-loading washing machine, they need to push the edge of the door away from the hinged end to apply force to the door and overcome the hinge's damping. Because the edge of the door away from the hinge is relatively close to the hinge, according to the torque formula (torque equals force multiplied by lever arm), users need to apply a large force to the door to achieve the torque required to overcome the hinge's damping. Obviously, this increases the difficulty for users to open and close the door, especially for children, the elderly, and other users with less strength.
[0058] This application discloses a drum washing machine that reduces the difficulty for users when opening and closing the drum washing machine door.
[0059] The drum washing machine provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.
[0060] In various embodiments of this application, "front side" and "rear side" refer to the distance between the drum washing machine and its components and the user when the door is closed. The side closer to the user is designated as "front side", and the side farther from the user is designated as "rear side".
[0061] like Figures 1 to 4 As shown in the figure, this application discloses a drum washing machine, including:
[0062] The cabinet 100 has an internal cavity. The cabinet 100 forms the overall appearance of the drum washing machine, and the internal cavity is configured to accommodate multiple components of the pulsator washing machine, such as the washing drum, electrical circuitry, drive components, and drainage components. The cabinet 100 can be rectangular for placement against a wall. Alternatively, the cabinet 100 can be cylindrical to accommodate the circular components inside the drum washing machine.
[0063] The housing 100 has a clothes inlet 110 that communicates with the receiving cavity. The clothes inlet 110 can be located on the front side of the housing 100, and clothes can be put into the washing drum through the clothes inlet 110.
[0064] A washing drum (not shown in the figure) is disposed within a receiving cavity, with its opening corresponding to the loading port 110. The washing drum is used to wash clothes, which are inserted into the washing cavity through the opening on the drum for washing. For example, the washing drum includes an outer drum and an inner drum. The outer drum is disposed within the housing 100, and the inner drum is disposed within the outer drum and is rotatable relative to the outer drum and the housing 100.
[0065] Door body 200, including:
[0066] The door body 210 has a hinged end 211 and a rotating end 212 distributed horizontally. The hinged end 211 is hinged to the housing 100 to open or close the garment opening 110. It should be noted that the door body 210 has a first end face and a second end face distributed horizontally. The first end face is located near the axis of rotation between the door body 210 and the housing 100, and the second end face is located away from the axis of rotation between the door body 210 and the housing 100. The hinged end 211 is one end of the door body 210 in the horizontal direction. Specifically, the hinged end 211 is a portion of the door body 210 extending from the first end face towards the second end face by a predetermined distance. The hinged end 211 has a first end face. This predetermined distance is determined according to specific design requirements and can be a fixed value or adjustable according to actual application. The rotating end 212 is another end of the door body 210 in the horizontal direction. Specifically, the rotating end 212 is the part of the door body 210 that extends a predetermined distance from the second end face towards the first end face. The rotating end 212 includes the second end face. The predetermined distance is determined according to specific design requirements and can be a fixed value or adjusted according to actual application.
[0067] For example, the door body 210 can be hinged to the housing 100 via a hinge assembly. The hinge assembly includes a hinge seat, a hinge shaft, and a hinge body. The hinge seat is connected to the housing 100, the hinge shaft is rotatably connected to the hinge seat, and the hinge body is rotatably connected to the hinge seat via the hinge shaft. The door body 210 is connected to the hinge body. The door body 210 is provided with an observation port 213, which extends through the door body 210 along its thickness direction. Through the observation port 213, the user can directly observe the tumbling of clothes in the washing drum, the dissolution of the detergent, etc.
[0068] An observation window 220 is provided, with one end located within and sealing the observation opening 213, and the other end protruding from the observation opening 213 toward the rear of the door body 210. For example, the observation window 220 can be made of plastic or glass to provide a transparent effect. Furthermore, when the door 200 is closed, the observation window 220 can also extend into the door seal of the garment opening 110 of the cabinet 100, thereby sealing the garment opening 110.
[0069] The door body 210 has a first edge 214 located at the hinge end 211 and a second edge 215 located at the rotation end 212. The maximum horizontal distance between the axis of the observation port 213 and the first edge 214 is L1, and the maximum horizontal distance between the axis of the observation port 213 and the second edge 215 is L2, where L1 is less than L2. It should be noted that the first edge 214 is a line on the first end face, and the second edge 215 is a line on the second end face. Specifically, the first edge 214 can be the edge of the door body 210 near the rotation axis as an orthographic projection along its thickness direction; the second edge 215 can be the edge of the door body 210 away from the rotation axis as an orthographic projection along its thickness direction.
[0070] For example, the axis of the observation port 213 is parallel to the thickness direction of the door body 210, and the clothes-throwing port 110 can be a round port with the axis of the round port passing through the center of the round port; or, the clothes-throwing port 110 can also be a square port with the axis of the square port passing through the center of the inscribed circle or the circumscribed circle of the square port.
[0071] In this application, the door 200 includes a door body 210 and an observation window 220. The door body 210 is provided with an observation opening 213. One end of the observation window 220 is located inside the observation opening 213 and seals the observation opening 213. The other end protrudes from the observation opening 213 along the rear side of the door body 210. The door body 210 has a hinge end 211 that is hinged to the housing 100, and a rotating end 212 that rotates around the hinge end 211. The door body 210 also has a first edge 214 located at the hinge end 211 and a second edge 215 located at the rotating end 212.
[0072] The minimum and maximum horizontal distance between the axis of the observation port 213 and the first edge 214 is L1, and the minimum and maximum horizontal distance between the axis of the observation port 213 and the second edge 215 is L2. L1 is less than L2, which means that the second edge 215 is farther from the axis of the observation port 213 than the first edge 214. Compared with the technical solution where the distances between the second edge 215 and the first edge 214 and the axis of the observation port 213 are the same, the second edge 215 of this application is farther from the hinge axis between the door body 210 and the box body 100. Thus, the lever arm when the second edge 215 of the door body 200 is moved to open the door is larger, which can better overcome the damping applied by the hinge when opening the door, making the door body 200 smoother during the opening and closing process, thus making it easier to open and close the door.
[0073] In some embodiments, please refer to Figure 2 The door body 200 also includes a baffle 230 and a cover 240. The cover 240 is located on the rear side of the door body 210, and the baffle 230 is located on the front side of the door body 210. The baffle 230 has a transparent area opposite to the observation port 213. For example, both the baffle 230 and the cover 240 can be connected to the door body 210 by means of adhesive, snap-fit, bolt connection, etc.
[0074] In one alternative embodiment, (L2 / L1) = 1.1 to 1.3. For example, (L2 / L1) can be 1.12, 1.15, 1.18, 1.2, 1.22, 1.26, 1.29, etc., and this application does not limit it.
[0075] If (L2 / L1) is less than 1.1, although the second edge 215 is farther from the axis of the observation port 213 than the first edge 214, which can solve the technical problem to a certain extent, the distance between the second edge 215 and the hinge axis is not large enough when (L2 / L1) is less than 1.1, which will weaken the effect of making it easier for users to open and close the door; if (L2 / L1) is greater than 1.3, the distance between the second edge 215 and the hinge axis will be too large, resulting in the door 200 occupying too much horizontal space, which will increase the horizontal size of the drum washing machine.
[0076] Therefore, in this embodiment, (L2 / L1) is controlled between 1.1 and 1.3, which allows the distance between the second edge 215 and the aforementioned hinge axis to be within a suitable range. This not only enhances the effect of making it easier for users to open and close the door, but also prevents the door 200 from occupying excessive lateral space and increasing the lateral dimensions of the drum washing machine. Of course, (L2 / L1) can also be less than 1.1 or greater than 1.3, and this application does not impose any restrictions on this.
[0077] In one optional embodiment, L1 = 110-150mm, and L2 = 125-170mm. For example, L1 can be equal to 115mm, 120mm, 128mm, 130mm, 135mm, 141mm, 146mm, 149mm, etc., and L2 can be equal to 126mm, 128mm, 130mm, 135mm, 141mm, 146mm, 155mm, 161mm, 167mm, etc. This application does not impose any limitations on these values.
[0078] If L1 is less than 110mm and L2 is less than 125mm, the increase in distance between the second edge 215 and the hinge axis is small, which weakens the effect of making it easier for users to open and close the door; if L1 is greater than 150mm and L2 is greater than 170mm, the distance between the second edge 215 and the hinge axis will be too large, causing the door 200 to occupy too much lateral space, which will increase the lateral size of the drum washing machine.
[0079] Therefore, in this embodiment, L1 is controlled between 110 and 150 mm, and L2 is controlled between 125 and 170 mm. This ensures that the distance between the second edge 215 and the hinge axis is within a suitable range. This not only enhances the ease with which the user can open and close the door, but also prevents the door 200 from occupying excessive lateral space and increasing the lateral dimensions of the drum washing machine. Of course, L1 can also be less than 110 mm or greater than 150 mm; L2 can also be less than 125 mm or greater than 170 mm.
[0080] In one alternative embodiment, please refer to Figure 3 The first edge 214 is arc-shaped and protrudes in the direction away from the rotating end 212. The first edge 214 is concentrically set with the observation port 213, and the second edge 215 extends in the vertical direction.
[0081] In this embodiment, the arc-shaped first edge 214 is located at the hinge end 211, and the first edge 214 protrudes in a direction away from the rotating end 212. The arc-shaped first edge 214 is less likely to interfere with other components during the rotation of the door 200. The second edge 215 extends vertically, so any position on the second edge 215 is far from the aforementioned hinge axis. The user can easily overcome the damping of the hinge and open or close the door 200 by moving any position on the second edge 215 without having to deliberately move a specific position on the second edge 215, which simplifies the opening and closing operation. Of course, the first edge 214 may also extend vertically or the second edge 215 may also be arc-shaped; this application does not limit this.
[0082] In one alternative embodiment, please continue to refer to Figure 3The door body 210 also has a third edge 216 and a fourth edge 217 that are spaced apart in the vertical direction. Both the third edge 216 and the fourth edge 217 extend in the horizontal direction, with the third edge 216 located above the fourth edge 217.
[0083] One end of the third edge 216 connects to the upper end of the first edge 214, and the other end of the third edge 216 connects to the upper end of the second edge 215; one end of the fourth edge 217 connects to the lower end of the first edge 214, and the other end of the fourth edge 217 connects to the lower end of the second edge 215. For example, the third edge 216 may be tangent to the first edge 214, and the fourth edge 217 may also be tangent to the first edge 214.
[0084] In this embodiment, the hinge end 211 is formed by the first edge 214, and the rotating end 212 is formed by the second edge 215, the third edge 216, and the fourth edge 217. Since the third edge 216 and the fourth edge 217 are parallel and the second edge 215 extends in the vertical direction, the rotating end 212 formed by the second edge 215, the third edge 216, and the fourth edge 217 is rectangular. Compared with the arc-shaped rotating end 212, the rectangular rotating end 212 has a larger area. Thus, the rotating end 212 can accommodate more components or increase the size of the components arranged on the rotating end 212, such as a door handle, which can improve the user's operational convenience.
[0085] In one optional embodiment, the radius of the first edge 214 is 115-130 mm, and the lengths of the third edge 216 and the fourth edge 217 are equal, with the length of the third edge 216 being 260-300 mm. For example, the radius of the first edge 214 is 116 mm, 118 mm, 120 mm, 123 mm, 125 mm, 128 mm, etc., and the length of the third edge 216 is 265 mm, 268 mm, 273 mm, 275 mm, 280 mm, 286 mm, 289 mm, 292 mm, 294 mm, 295 mm, 299 mm, etc., but this application does not impose any limitations on these.
[0086] If the radius of the first edge 214 is less than 115mm and the length of the third edge 216 is less than 260mm, the increase in the distance between the second edge 215 and the hinge axis will be small, which will weaken the effect of making it easier for users to open and close the door. If the radius of the first edge 214 is greater than 130mm and the length of the third edge 216 is greater than 300mm, the distance between the second edge 215 and the hinge axis will be too large, causing the door 200 to occupy too much lateral space, which will increase the lateral size of the drum washing machine.
[0087] Therefore, in this embodiment, the radius of the first edge 214 is controlled between 115 and 130 mm, and the length of the third edge 216 is controlled between 260 and 300 mm. This allows the distance between the second edge 215 and the hinge axis to be within a suitable range. This not only enhances the ease with which the user can open and close the door, but also prevents the door 200 from occupying excessive lateral space and increasing the lateral dimensions of the drum washing machine. Of course, the radius of the first edge 214 can also be less than 115 mm or greater than 130 mm; the length of the third edge 216 can also be less than 260 mm or greater than 300 mm.
[0088] In one alternative embodiment, the washing tub includes:
[0089] A first tub is disposed within a receiving cavity for washing clothes. For example, the first tub includes a first outer tub and a first inner tub. The first outer tub is disposed within a housing 100, and the first inner tub is disposed within the first outer tub and is rotatable relative to the first outer tub and the housing 100.
[0090] The second tub is disposed within the receiving cavity and arranged horizontally alongside the first tub. The second tub is used for washing clothes. For example, the second tub includes a second outer tub and a second inner tub. The second outer tub is disposed within the housing 100, and the second inner tub is disposed within the second outer tub and is rotatable relative to the second outer tub and the housing 100.
[0091] The 110 emergency call center includes:
[0092] The first garment inlet is set in accordance with the opening of the first cylinder. Here, the first garment inlet can be set on the front side of the box 100, and clothes can be put into the first cylinder through the first garment inlet.
[0093] The second garment inlet is provided in accordance with the opening of the second cylinder. The second garment inlet can be located on the front side of the box 100, and clothes can be put into the second cylinder through the second garment inlet.
[0094] There are two doors 200, each of which is rotatably connected to the box 100. The two doors 200 are respectively engaged with the first garment inlet and the second garment inlet. That is, one door 200 can open or close the first garment inlet, and the other door 200 can open or close the second garment inlet.
[0095] In this embodiment, the washing drum includes a first drum and a second drum that are spaced apart in the horizontal direction. The first drum and the second drum are two completely independent drums and are not connected. Therefore, the first drum and the second drum can operate independently to achieve zone washing. Zone washing can separate clothes with different washing requirements. For example, underwear and other intimate clothing and outerwear need to be washed separately to avoid cross-contamination and ensure the washing quality of the clothes.
[0096] In some embodiments, the front side of the housing 100 is provided with a first sub-slot and a second sub-slot, which are spaced apart and not connected. When both doors 200 are closed, one of the doors 200 is accommodated in the first sub-slot and the other in the second sub-slot. Thus, when the two doors 200 are closed, they are separated by the solid material of the housing 100 located between the first and second sub-slots, which makes the two doors 200 far apart, thereby increasing the lateral dimension of the drum washing machine.
[0097] In one alternative embodiment, please refer to Figure 1 The front side of the box 100 is provided with a first sub-slot and a second sub-slot that are connected in the horizontal direction. The first clothes inlet is located on the bottom wall of the first sub-slot, and the second clothes inlet is located on the bottom wall of the second sub-slot.
[0098] When both doors 200 are closed, one of the doors 200 is accommodated in the first sub-slot and the other is accommodated in the second sub-slot, and at least one of the doors 200 is located at the junction of the first sub-slot and the second sub-slot.
[0099] In this embodiment, the first sub-slot and the second sub-slot are connected. Therefore, there is no solid material between the first sub-slot and the second sub-slot. Furthermore, when both doors 200 are closed, at least one of the doors 200 is located at the connection between the first sub-slot and the second sub-slot. In other words, this embodiment utilizes the space of the solid material in the previous embodiment to accommodate the door 200. This reduces the lateral space occupied by the door 200 in the cabinet 100, thereby reducing the lateral dimensions of the drum washing machine.
[0100] In a further embodiment, when both doors 200 are closed, the outer surfaces of the two doors 200 are flush with the front surface of the casing 100 to prevent the doors 200 from protruding forward from the first and second sub-slots, thereby reducing the longitudinal dimension of the drum washing machine.
[0101] In one alternative embodiment, please continue to refer to Figure 1 The first sub-slot and the second sub-slot together form the receiving tank 120, which is racetrack shaped.
[0102] In this embodiment, the racetrack-shaped receiving groove 120 has a first arc surface and a second arc surface distributed in the horizontal direction, and a first plane and a second plane distributed in the vertical direction. The two ends of the first plane are tangent to the upper ends of the first arc surface and the upper ends of the second arc surface, respectively. The two ends of the second plane are tangent to the lower ends of the first arc surface and the lower ends of the second arc surface, respectively. It can be seen that there is no non-smooth transition area on the inner wall of the racetrack-shaped receiving groove 120. This can avoid generating large stress on the inner wall of the receiving groove 120, thereby extending the service life of the box 100.
[0103] In one alternative embodiment, please refer to Figure 4 When both doors 200 are closed, the rotating ends 212 of the two doors 200 are the ends of the two doors 200 that are close to each other. That is, the directions from the hinge end 211 to the rotating end 212 of the two doors 200 are opposite, and the gap between the rotating ends 212 of the two doors 200 is less than 3mm. For example, the gap here can be 0.8mm, 1mm, 1.5mm, 1.8mm, 2.1mm, 2.5mm, 2.8mm, etc., and this application does not limit it.
[0104] In this embodiment, when both doors 200 are closed, the gap between the rotating ends 212 of the two doors 200 is less than 3mm. This allows the two doors 200 to be spaced closer together, reducing the lateral space occupied by the doors 200 in the housing 100, thereby reducing the lateral dimensions of the drum washing machine. Of course, the gap between the rotating ends 212 of the two doors 200 can also be greater than or equal to 3mm, and this application does not impose any limitation on this.
[0105] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
