Description

Technical Field

[0001] This application relates to the field of washing machine technology, and more specifically, to an inner door assembly, a washing tub, and a front-loading washing machine. Background Technology

[0002] Currently, washing machines can be categorized into front-loading, top-loading, and other types based on different washing needs. A typical front-loading washing machine includes an outer tub, an inner tub, and other components. The inner tub is fitted inside the outer tub; the outer tub holds the water, while the inner tub is the washing tub. During the washing process, water flows back and forth between the inner and outer tubs, and the washing task is completed by the rotation of the inner tub, which creates tumbling and other actions on the items being washed.

[0003] To prevent water from flowing out of the inner tub during washing or rinsing, a seal is typically installed on the inner door assembly to seal the connection between the inner door assembly and the inner tub. However, during the spin-drying process in a front-loading washing machine, the inner tub rotates at high speed relative to the outer tub. This causes the seal, which is located on the inner door assembly and contacts the inner tub, to experience significant friction during high-speed rotation. This reduces the lifespan of the seal and consequently lowers the reliability of the front-loading washing machine. Utility Model Content

[0004] This application provides an inner door assembly, a washing tub, and a drum washing machine for a front-loading washing machine, which can improve the service life of the inflatable sealing ring and thus improve the reliability of the drum washing machine.

[0005] In a first aspect, this application provides an inner door assembly for a front-loading washing machine. The inner door assembly is used to cooperate with the washing inner tub of the front-loading washing machine. The inner door assembly includes a door body, on which an inflatable sealing ring is disposed. The inflatable sealing ring is disposed around the center of the door body. When the inflatable sealing ring is inflated, it deforms and comes into contact with the washing inner tub of the front-loading washing machine to form a seal between the inner door assembly and the washing inner tub. When the inflatable sealing ring is deflated, it deforms and disengages from the washing inner tub of the front-loading washing machine to release the seal between the inner door assembly and the washing inner tub.

[0006] In the above technical solution, by setting an inflatable sealing ring on the door body, the inflatable sealing ring will deform when it is inflated or deflated. In this way, when the drum washing machine is in the spin-drying stage, the inflatable sealing ring can be deflated to deform and separate from the inner washing tub. At this time, the inflatable sealing ring will not contact the inner washing tub. Therefore, when the inner washing tub rotates at high speed, the inflatable sealing ring will not be subjected to friction, thereby improving the service life of the inflatable sealing ring and thus improving the reliability of the drum washing machine.

[0007] In some embodiments, an air pump is also provided on the door body, and the air pump is connected to the air passage of the inflatable sealing ring.

[0008] In the above technical solution, by setting up an air pump, which is connected to the air circuit of the air-filled sealing ring, the air pump can inflate and deflate the air at a relatively fast speed, thus enabling the air-filled sealing ring to deform quickly. This can improve the speed at which the air-filled sealing ring forms a seal or releases a seal, thereby increasing the speed of washing, rinsing or dehydrating the inner tub of the washing machine.

[0009] In some embodiments, an observation window is also provided in the middle of the door body, and the observation window is made of transparent material.

[0010] In the above technical solution, the observation window is made of transparent material. Since transparent material can break through physical barriers and realize the extension of vision and the connection of space, the observation window made of transparent material can make it easy for users to observe the inside of the washing tub.

[0011] In some embodiments, the door body is also provided with a blocking member that protrudes towards the inner washing tub of the front-loading washing machine.

[0012] In the above technical solution, by setting a blocking member on the door body that protrudes towards the inner tub of the washing machine, the blocking member can extend into the inner tub when the inner tub is spinning. The blocking member can effectively limit the movement of the laundry items between the bottom wall of the inner tub and the blocking member during the spinning process, thereby reducing the probability of the laundry items clogging the space between the inner door assembly and the inner tub.

[0013] In some embodiments, the door body is also provided with a water inlet assembly, which connects the inner washing tub of the drum washing machine to an external water source.

[0014] In the above technical solution, by setting a water inlet component on the door body, the water inlet component connects the inner washing tub and the external water source. Through the water inlet component, the external water source can be quickly guided into the inner washing tub during the washing or rinsing process, thereby improving the speed of the washing or rinsing process.

[0015] In some embodiments, the door body is further provided with a drainage assembly, which includes a drainage pipe and a water pump. One end of the drainage pipe is connected to the water pump, and the other end is connected to the washing tub of the front-loading washing machine.

[0016] In the above technical solution, by setting up a drain pipe with one end connected to a water pump and the other end connected to the inner tub of the washing machine, the water in the inner tub can be quickly discharged because the water pump can generate a large suction force.

[0017] Secondly, embodiments of this application provide a washing tub, including an outer washing tub, an inner washing tub, and an inner door assembly provided in any of the embodiments of the first aspect. The inner washing tub is rotatably disposed inside the outer washing tub and has a first opening. The inner door assembly is rotatably disposed on the side of the outer washing tub near the first opening, and the inner door assembly opens or closes the first opening.

[0018] In some embodiments, the washing tub further includes a first baffle, which is disposed around the inner wall of the washing tub near the end of the first opening. A first loading / unloading port is disposed in the middle of the first baffle, and a plurality of second openings are disposed around the first loading / unloading port on the edge of the first baffle.

[0019] In some embodiments, the washing tub further includes a plurality of storage plates arranged around the inner wall of the washing tub, the outer contour of the storage plates being arc-shaped, with the center of the arc located on the central axis of the washing tub.

[0020] Thirdly, embodiments of this application provide a front-loading washing machine, including a washing tub provided in any one of the embodiments of the first aspect disposed within the casing. Attached Figure Description

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0039] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0042] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0043] Currently, washing machines can be categorized into front-loading, top-loading, and other types based on different washing needs. A typical front-loading washing machine includes an outer tub, an inner tub, and other components. The inner tub is fitted inside the outer tub; the outer tub holds the water, while the inner tub is the washing tub. During the washing process, water flows back and forth between the inner and outer tubs, and the washing task is completed by the rotation of the inner tub, which creates tumbling and other actions on the items being washed.

[0044] To prevent water from flowing out of the inner tub during washing or rinsing, a seal is typically installed on the inner door assembly to seal the connection between the inner door assembly and the inner tub. However, during the spin-drying process in a front-loading washing machine, the inner tub rotates at high speed relative to the outer tub. This causes the seal, which is located on the inner door assembly and contacts the inner tub, to experience significant friction during high-speed rotation. This reduces the lifespan of the seal and consequently lowers the reliability of the front-loading washing machine.

[0045] Based on the above considerations, in order to solve the technical problem that the seals on the inner door assembly in the prior art are subject to large frictional forces when rotating at high speed, thus reducing the reliability of the drum washing machine, this application provides an inner door assembly for a drum washing machine. The inner door assembly is used to cooperate with the washing inner tub of the drum washing machine. The inner door assembly includes a door body, on which an inflatable sealing ring is provided. The inflatable sealing ring is arranged around the center of the door body. When the inflatable sealing ring is inflated, it deforms and contacts the washing inner tub of the drum washing machine to form a seal between the inner door assembly and the washing inner tub. When the inflatable sealing ring is deflated, it deforms and disengages from the washing inner tub of the drum washing machine to release the seal between the inner door assembly and the washing inner tub.

[0046] In this inner door assembly for a front-loading washing machine, an inflatable sealing ring is installed on the door body. Because the inflatable sealing ring deforms when inflated or deflated, when the washing machine is in the spin cycle, the inflatable sealing ring can be deflated to deform and separate from the inner tub. At this time, the inflatable sealing ring will not contact the inner tub, so when the inner tub rotates at high speed, the inflatable sealing ring will not be subjected to friction, thereby improving the service life of the inflatable sealing ring and thus improving the reliability of the front-loading washing machine.

[0047] Please refer to Figure 1-4, Figure 1 A schematic diagram of the structure of an inner door assembly for a front-loading washing machine provided in some embodiments of this application; Figure 2 A schematic diagram of the structure of an inner door assembly for a front-loading washing machine provided in some embodiments of this application (showing the inflatable sealing ring in an inflatable state). Figure 3 A schematic diagram of the structure of an inner door assembly for a front-loading washing machine provided for some embodiments of this application (showing the deflated state of the inflatable sealing ring). Figure 4 This is a schematic diagram of the usage state structure of an inner door assembly for a front-loading washing machine provided in some embodiments of this application. Embodiments of this application provide an inner door assembly 1 for a front-loading washing machine. The inner door assembly 1 is used to cooperate with the washing inner tub 22 of the front-loading washing machine 3. The inner door assembly 1 includes a door body 11, on which an inflatable sealing ring 12 is provided. The inflatable sealing ring 12 is arranged around the center of the door body 11. When the inflatable sealing ring 12 is inflated, it deforms and comes into contact with the washing inner tub 22 of the drum washing machine 3 to form a seal between the inner door assembly 1 and the washing inner tub 22; when the inflatable sealing ring 12 is deflated, it deforms and separates from the washing inner tub 22 of the drum washing machine 3 to release the seal between the inner door assembly 1 and the washing inner tub 22.

[0048] The inflatable sealing ring 12 can be a flexible sealing element that achieves sealing by inflating compressed air and retracts to release the seal after deflating, such as an air-expanding sealing strip.

[0049] The inflatable sealing ring 12 can be set on the outer periphery of the door body 11, and the inflatable sealing ring is set around the center of the door body 11; the inflatable sealing ring 12 can also be set on the edge of the door body 11, and the inflatable sealing ring 12 is set around the center of the door body 11.

[0050] The inflatable sealing ring 12 can be used with an air pump that only has an inflation function. The air pump is used to inflate the inflatable sealing ring 12, and the air is released by setting an exhaust hole on the inflatable sealing ring 12.

[0051] The inflatable sealing ring 12 and the door body 11 can be fixedly connected, such as by adhesive bonding, or they can be detachably connected, such as by a slot and a block engaging. The detachable connection allows for the fixing of the inflatable sealing ring 12 and the door body 11, which is more convenient for replacing the inflatable sealing ring 12 compared to a fixed connection.

[0052] like Figure 4As shown, in this embodiment, by providing an inflatable sealing ring 12 on the door body 11, the inflatable sealing ring 12 will deform when inflated or deflated. Thus, when the drum washing machine 3 is in the spin-drying stage, the inflatable sealing ring 12 can be deflated to deform and separate from the inner washing tub 22. At this time, the inflatable sealing ring 12 will not contact the inner washing tub 22. Therefore, when the inner washing tub 22 rotates at high speed, the inflatable sealing ring 12 will not be subjected to friction, thereby improving the service life of the inflatable sealing ring 12 and thus improving the reliability of the drum washing machine 3.

[0053] Simultaneously, during spin-drying, the deflation of the air-sealing ring 12 causes it to deform and detach from the inner tub 22, thereby releasing the seal between the inner door assembly 1 and the inner tub 22. This allows water discharged from the inner tub 22 during spin-drying to drain along the space between the inner door assembly 1 and the inner tub 22. Since the space between the inner door assembly 1 and the inner tub 22 is larger than the size of the drain hole on the non-perforated inner tub of a washing machine in the prior art, this larger space causes a gap between the inner tub 22 and its exterior. The increased size of the drainage channel improves drainage efficiency when the inner tub 22 needs to drain. During washing or rinsing, the inflation of the air-sealing ring 12 causes it to deform and come into contact with the inner tub 22, thus forming a seal between the inner door assembly 1 and the inner tub 22. This prevents water in the inner tub 22 from being discharged to the outside of the inner tub 22 through the space between the inner door assembly 1 and the inner tub 22 during washing or rinsing, thereby reducing the probability of water wastage in the inner tub 22 during washing or rinsing.

[0054] In some embodiments, please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of an inner door assembly for a front-loading washing machine provided in some embodiments of this application (showing an air pump). An air pump 13 is also provided on the door body 11, and the air pump 13 is connected to the air passage of the inflatable sealing ring 12.

[0055] Because the slow speed at which the inflatable sealing ring 12 forms or releases a seal will slow down the washing, rinsing, or spin-drying speed of the inner tub 22 of the front-loading washing machine 3, this embodiment uses an air pump 13 connected to the air circuit of the inflatable sealing ring 12. Since the air pump 13 has a relatively fast inflation and deflation response, the inflatable sealing ring 12 deforms quickly during inflation or deflation, thereby increasing the speed at which it forms or releases a seal, and consequently increasing the washing, rinsing, or spin-drying speed of the inner tub 22. Specifically, during washing or rinsing, the air pump 13 inflates the inflatable sealing ring 12. The rapid deformation during inflation causes surface-to-surface contact between the side of the inflatable sealing ring 12 facing the inner tub 22 and the side of the inner tub 22 facing the inflatable sealing ring 12. The air pump 13 seals the inner door assembly 12, allowing a rapid seal to form between the inner door assembly 1 and the inner tub 22. This prevents water inside the air-filled sealing ring 12 from leaking out of the tub, creating a quick washing or rinsing environment within the tub and increasing washing or rinsing speed. During spin-drying, the air pump 13 deflates the air-filled sealing ring 12, causing it to deform rapidly. This causes the side of the air-filled sealing ring 12 facing the tub 22 to detach from the side of the tub 22 facing the air-filled sealing ring 12, quickly releasing the seal between the inner door assembly 1 and the tub 22. This allows water to flow within the space between the inner door assembly 1 and the tub 22, creating a drainage channel between the tub 22 and the outside for rapid drainage, further increasing spin-drying speed.

[0056] Meanwhile, the air pump 13 can be a miniature air pump, which is small in size and therefore easy to install on the inner door assembly 1.

[0057] In some embodiments, please refer to Figure 6 , Figure 6 This is a structural schematic diagram of an inner door assembly for a front-loading washing machine provided in some embodiments of this application (showing an observation window). An observation window 14, made of transparent material, is also provided in the middle of the door body 11.

[0058] Transparent materials can be transparent glass or transparent plastic.

[0059] In this embodiment, the observation window 14 is made of transparent material. Since transparent material can break through physical barriers and extend vision and connect space, the observation window 14 made of transparent material can facilitate the user to observe the inside of the washing inner tub 22.

[0060] In some embodiments, please refer to Figure 7 , Figure 7This is a structural schematic diagram of an inner door assembly for a front-loading washing machine provided in some embodiments of this application (showing a blocking member). The door body 11 is also provided with a blocking member 15 that protrudes toward the washing inner tub 22 of the front-loading washing machine 3.

[0061] In an embodiment where an observation window 14 is provided in the middle of the door body 11, the blocking member 15 may be a structure formed by the side of the observation window 14 facing the inner washing tub 22 protruding towards the inner washing tub 22.

[0062] The blocking element 15 can be a plate-like structure consisting of a single plate, or a mesh structure formed by several intersecting beams.

[0063] The blocking element 15 can be made of a transparent material, such as transparent plastic or transparent glass.

[0064] During the spin-drying process, the high-speed rotating inner tub 22 can easily cause the laundry to move to the opening of the inner tub 22, increasing the probability of the laundry clogging the space between the inner door assembly 1 and the inner tub 22. Therefore, in this embodiment, a blocking member 15 protruding towards the inner tub 22 of the drum washing machine 3 is provided on the door body 11. When the inner tub 22 is spin-drying, the blocking member 15 can extend into the inner tub 22. The blocking member 15 can effectively limit the movement of the laundry during the spin-drying process to between the bottom wall of the inner tub 22 and the blocking member 15, thereby reducing the probability of the laundry clogging the space between the inner door assembly 1 and the inner tub 22. This can improve the efficiency of water draining from the space between the inner door assembly 1 and the inner tub 22 during the spin-drying process.

[0065] In some embodiments, please refer to Figure 8 , Figure 8 This is a structural schematic diagram of an inner door assembly for a front-loading washing machine provided in some embodiments of this application (showing a water inlet assembly and a drainage assembly). A water inlet assembly 16 is also provided on the door body 11, which connects the inner washing tub 22 of the front-loading washing machine 3 to an external water source. The water inlet assembly 16 may include a water inlet pipe 161 and a water inlet valve 162. One end of the water inlet pipe 161 is connected to the inner washing tub 22, and the other end is connected to an external water source. The water inlet valve 162 is located on the water inlet pipe 161 and controls the opening and closing of the water inlet pipe 161.

[0066] In this embodiment, by providing a water inlet assembly 16 on the door body 11, the water inlet assembly 16 connects the washing inner tub 22 to the external water source. The water inlet assembly 16 can quickly guide the external water source into the washing inner tub 22 during the washing or rinsing process, thereby increasing the speed of the washing or rinsing process.

[0067] In some embodiments, please refer to Figure 8 The door body 11 is also provided with a drainage component 17, which includes a drainage pipe 171 and a water pump 172. One end of the drainage pipe 171 is connected to the water pump 172, and the other end is connected to the washing inner tub 22 of the drum washing machine 3.

[0068] In this embodiment, by setting a drain pipe 171 with one end connected to a water pump 172 and the other end connected to the inner washing tub 22, the water in the inner washing tub 22 can be quickly discharged because the water pump 172 can generate a large suction force.

[0069] Meanwhile, a miniature water pump can be used for pumping water. Due to the small size of the miniature water pump, it is also convenient to install the miniature water pump on the inner door assembly 1.

[0070] In some embodiments, please refer to Figure 9 , Figure 9 This is a schematic diagram of the structure of a washing tub provided in some embodiments of this application. Embodiments of this application provide a washing tub 2, including an outer washing tub 21, an inner washing tub 22, and an inner door assembly 1 provided in any of the above embodiments. The inner washing tub 22 is rotatably disposed within the outer washing tub 21, and the inner washing tub 22 has a first opening 221. The inner door assembly 1 is rotatably disposed on the side of the outer washing tub 21 near the first opening 221, and the inner door assembly 1 opens or closes the first opening 221.

[0071] In some embodiments, please refer to Figures 9-10 , Figure 10 The diagram below shows the structure of a washing tub provided in some embodiments of this application (showing a first baffle). The inner washing tub 22 further includes a first baffle 222, which is disposed around the inner wall of the inner washing tub 22 near the end of the first opening 221. A first loading / unloading port 2221 is provided in the middle of the first baffle 222, and a plurality of second openings 2222 are provided on the edge of the first baffle 222. The plurality of second openings 2222 are disposed around the first loading / unloading port 2221.

[0072] The outer contour of the first baffle 222 matches the inner contour of the inner wall of the inner tub 22. This shape matching makes it easier to assemble the first baffle 222 with the inner wall of the inner tub 22.

[0073] The first baffle 222 and the inner wall of the inner washing tub 22 can be fixedly connected, such as by welding or integral molding. Alternatively, they can be detachably connected, such as by the snap-fit ​​of a slot and a block, or the threaded engagement of external and internal threads. They can also be rotatably connected, with the first baffle 222 and the inner washing tub 22 linked by a hinge, allowing the first baffle 222 to rotate relative to the inner wall of the inner washing tub 22.

[0074] In the projection plane perpendicular to the central axis of the inner washing tub 22, the orthographic projection shape of the first loading / unloading port 2221 and the orthographic projection shape of the second opening 2222 can both be circular. In the embodiment where the orthographic projection shapes of the first loading / unloading port 2221 and the second opening 2222 are both circular, the radius of the first loading / unloading port 2221 is much larger than the radius of the second opening 2222, and the size of the radius of the first loading / unloading port 2221 must be sufficient to meet the requirement of convenient loading and unloading of washing items.

[0075] In this embodiment, a first baffle 222 is provided on the inner wall of the inner tub 22 near the first opening 221. Since the first baffle 222 is located at the first opening 221, it can block the moving laundry items when the inner tub 22 rotates at high speed, thus limiting the position of the laundry items between the first baffle 222 and the bottom wall of the inner tub 22. This reduces the probability of laundry items clogging the space between the inner door assembly 1 and the inner tub 22. At the same time, by providing a second opening 2222 on the first blocking member 15, water can flow through the second opening 2222 to the space between the inner door assembly 1 and the inner tub 22 when drainage is required. Therefore, the design of the position and structure of the first blocking member 15 can improve the drainage efficiency.

[0076] Meanwhile, a first loading / unloading port 2221 is provided in the middle of the first baffle 222, through which the washing items in the inner washing tub 22 can be easily loaded or unloaded.

[0077] In some embodiments, please refer to Figure 9 , Figures 11-12 , Figure 11 A schematic diagram of the structure of a washing tub provided for some embodiments of this application (showing a shelf); Figure 12 The following is a schematic diagram of the structure of a washing tub provided in some other embodiments of this application (showing the storage plates). The inner washing tub 22 also includes a plurality of storage plates 223, which are arranged around the inner wall of the inner washing tub 22. The outer contour of the storage plates 223 is arc-shaped, and the center of the arc is on the central axis of the inner tub.

[0078] Through holes may or may not be made on shelf 223.

[0079] The shelf 223 and the inner wall of the washing tub 22 can be detachably connected, such as by a slot and a locking mechanism. This detachable connection allows for quick installation and removal of the shelf 223 according to different usage requirements.

[0080] like Figure 11 As shown, there may be a first gap between adjacent shelves 223 among the multiple shelves 223. The first gap between adjacent shelves 223 can provide space for installing other components, such as space for installing lifting ribs 224.

[0081] like Figure 12 As shown, multiple shelves 223 can be directly connected, and multiple shelves 223 can also be a one-piece molded structure.

[0082] Because the inner tub 22 is conical, when viewed from the end of the inner tub 22 near the first opening 221 to the end of the inner tub 22 away from the first opening 221, the inner wall surface of the inner tub 22 is a gentle slope. During the spin-drying process, the high-speed rotating inner tub 22 makes it easier for the washed items to move to the first baffle 222 and accumulate, thereby reducing the spin-drying effect. Therefore, in this embodiment, by setting multiple placement plates 223 and defining the outer contour of the placement plates 223 as arc-shaped, with the center of the arc on the central axis of the inner tub 22, after the placement plates 223 are installed, when viewed from the end of the inner tub 22 near the first opening 221 to the end of the inner tub 22 away from the first opening 221, the inner surface of the placement plate 223 forms a plane. In this way, during the spin-drying process, the high-speed rotating inner tub 22 is less likely to cause the washed items to move to the first baffle 222 and accumulate, thereby improving the spin-drying effect.

[0083] In some embodiments, please refer to Figure 13 and 14 , Figure 13 This is a schematic diagram of the structure of a front-loading washing machine provided in some embodiments of this application; Figure 14 This is a schematic diagram of the structure of a front-loading washing machine provided in some other embodiments of this application. An embodiment of this application provides a front-loading washing machine 3, including a housing 31, within which a washing tub 2, as provided in any of the above embodiments, is disposed.

[0084] The front-loading washing machine 3 may also include an outer door 32, which is rotatably mounted on the housing 31.

[0085] The front-loading washing machine 3 may also include a shock-absorbing assembly 33, which may include a shock absorber 332 and a suspension spring 331. The shock absorber 332 and the suspension spring 331 are built-in. The shock absorber 332 is located at the bottom inside the housing 31 of the front-loading washing machine 3 and is connected to the outer washing tub 21 via a shock-absorbing foot. The suspension spring 331 is located at the top inside the housing 31 of the front-loading washing machine 3, and the other end of the suspension spring 331 is connected to the outer washing tub 21. The shock-absorbing assembly 33, consisting of the shock absorber 332 and the suspension spring 331, is an important component of the front-loading washing machine 3. It can effectively reduce the vibration and noise generated by the front-loading washing machine 3 during operation, thereby improving the stability and service life of the washing machine.

[0086] The front-loading washing machine 3 may also include a water inlet valve, a water outlet valve, a water level sensor, a motor, a speed reducer, and control components. These components automatically control the inflow and outflow of water, allowing the washing machine 3 to perform washing, rinsing, and spin-drying processes according to preset programs. This simplifies operation and makes the washing process more even and efficient. The water level sensor detects the water level to control water usage, helping to conserve water resources and ensure consistent washing results. The washing machine motor is the power source for the front-loading washing machine 3, while the speed reducer controls the motor's rotation speed, precisely controlling the washing, rinsing, and spin-drying processes to improve washing efficiency and protect clothes from excessive wear. The control components receive user input commands and control the operation of the aforementioned components accordingly, allowing users to remotely control the operation of the front-loading washing machine 3, such as starting a wash, selecting a washing mode, and setting the washing time.

[0087] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0088] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
