Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, specifically to a multi-zone washing machine. Background Technology

[0002] As living standards continue to improve, people are demanding more from the details of daily life. For example, when washing clothes, people sort them for washing, and the types of sorting are becoming increasingly diverse. To meet this demand, multi-zone washing machines have emerged on the market.

[0003] For example, a vertically stacked double-drum integrated model, as disclosed in CN201310289777.X, uses a double-drum design. The lower drum is a large-capacity drum with a capacity of 7-12kg and a diameter of 450-540mm, responsible for washing main garments; the upper drum is a small-capacity drum with a capacity of 3-5kg and a diameter of 200-250mm, responsible for washing children's clothes or underwear. Another example is a multi-drum integrated model, as disclosed in CN202310308156.5, which consists of a conventional 7-12kg large-capacity drum, a 3-5kg small-capacity drum, and two mini drums with a capacity of less than 1kg, to meet the needs of a family with more separate washing areas.

[0004] For washing machines with the aforementioned structures, issues arise regarding overall installation strength and vibration stability. When a dual-drum vertical layout is adopted, the overall height typically reaches 1200-1350mm, causing the center of gravity to shift upwards (the standard height of a washing machine is 850mm). This increases the vibration amplitude during spin-drying and weakens the overall connection strength. Based on this, the upper drum of CN201310289777.X can only be a small 3-5kg drum, while CN202310308156.5 places the smallest mini drum at the very top to reduce the installation strength requirements of the upper drum. However, this not only limits the size of the upper drum but also increases the distance from the upper drum opening to the ground. For the average Asian woman's height, this requires users to raise their arms above shoulder height to load clothes, severely impacting the user experience. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a multi-zone washing machine that facilitates the loading and unloading of clothes, in light of the current state of the technology.

[0006] The second technical problem to be solved by this utility model is to provide a multi-zone washing machine that can reduce vibration and thus meet more installation needs, in light of the current state of the technology.

[0007] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows:

[0008] A multi-zone washing machine includes a frame and a small-zone structure located in the middle of the frame. The small-zone structure is a drawer-type washing assembly. The drawer-type washing assembly includes a drawer shell and a pulsator assembly located in the drawer shell. An elastic element is provided on the inner bottom wall of the drawer shell. The bottom of the pulsator assembly is located in the drawer shell with shock absorption by the elastic element.

[0009] With the above structure, the small compartment for washing small clothes is located in the middle of the machine, placing it at a height that is most comfortable for Asian women to operate. Furthermore, in the drawer-type washing assembly, the bottom of the impeller assembly is fitted into the drawer shell with an elastic element for vertical shock absorption. During washing, this effectively cushions the vibration of the impeller assembly, reducing vibration in the small compartment.

[0010] Preferably, mounting bosses are provided on both sides of the drawer shell, and the elastic element is a spring located at each corner of the mounting boss. A support edge extending outward and supported by the spring is provided on the lower middle part of the side wall of the impeller assembly. By adopting the above structure, placing the small-section shock-absorbing structure in the lower middle part of the impeller assembly instead of directly at the bottom helps reduce the vibration requirements of the elastic element on the impeller assembly in terms of height, further improving the buffering and shock absorption effect.

[0011] In this utility model, the inner sidewall of the frame and the outer sidewall of the drawer-type cleaning component are provided with a guide rail assembly that can guide and cooperate with the drawer. The inner sidewall of the frame and the outer sidewall of the drawer-type cleaning component are provided with a control structure that can cancel the load-bearing and guiding function of the slide rail assembly on the drawer-type cleaning component when the drawer-type cleaning component is pushed in, and restore the load-bearing and guiding function of the slide rail assembly on the drawer-type cleaning component when the drawer-type cleaning component is pulled out.

[0012] Because the drawer-type structure requires slide rails for pushing, pulling, and load-bearing, and these slide rails have clearance, the vibrations generated when the drawer-type cleaning component operates at high speed during washing or spin-drying are amplified by these clearances. This not only causes collision wear on the slide rails but also increases noise. This invention incorporates a control structure that locks the clearance between the slide rails after the drawer-type cleaning component is pushed into the machine, eliminating the slide rails' load-bearing function and relying on the control structure for load-bearing. This allows the vibrations generated by the drawer-type cleaning component to be directly transmitted to the machine frame instead of through the slide rails. When the drawer-type cleaning component is pulled out, the control structure disengages, automatically restoring the slide rails' load-bearing and guiding function.

[0013] Preferably, the control structure includes a first limiting member and a second limiting member. The first limiting member is disposed on the inner side wall of the frame, and the second limiting member is disposed on the outer side wall of the drawer-type cleaning assembly. When the drawer-type cleaning assembly is pushed in, the first and second limiting members cooperate to achieve upper and lower limiting. When the drawer-type cleaning assembly is pulled out, the first and second limiting members disengage. This structure facilitates installation and allows for easy switching between the limiting and disengaging states as the drawer-type cleaning assembly is pushed or pulled out.

[0014] Preferably, the first limiting member and the second limiting member are interlocked. More preferably, the first limiting member has a forward-facing insertion port, and correspondingly, the second limiting member has a rearward-facing plug. When the drawer-type cleaning assembly is pushed in, the plug is inserted into the insertion port to form a limiting position. The above structure is a preferred method for the first and second limiting members to mutually limit and disengage, and it is simple in structure and convenient for installation and operation.

[0015] Preferably, the slide rail assembly includes a sliding sleeve and a guide rail. The sliding sleeve is disposed on the inner side wall of the frame and extends front to back. The guide rail is disposed on the outer side wall of the drawer-type cleaning assembly, and at least the outer portion is slidably constrained within the sliding sleeve. There is a fitting clearance between the sliding sleeve and the guide rail. The specific structure of the above slide rail assembly can adopt existing technology, and will not be described in detail here.

[0016] In this invention, when the first limiting member is disengaged from the second limiting member, the sliding sleeve provides load-bearing support for the drawer-type cleaning assembly via the guide rail; when the first limiting member is engaged with the second limiting member, the first limiting member provides load-bearing support for the drawer-type cleaning assembly via the second limiting member, while the clearance between the sliding sleeve and the guide rail remains constant. This structure isolates the slide rail assembly during cleaning, reducing vibration.

[0017] To facilitate assembly, the inner wall of the frame is provided with a mounting sheet metal that extends front and rear, and the inner side of the mounting sheet metal is formed with a mounting groove for mounting the slide rail assembly and control structure.

[0018] Preferably, the slide rail assembly includes a sliding sleeve and a guide rail. The sliding sleeve is disposed on the inner wall of the mounting sheet metal, and the guide rail is disposed on the outer wall of the drawer-type cleaning assembly. Two sets of first limiting members are disposed on the inner wall of the mounting sheet metal, with one set above the sliding sleeve and the other below it. More preferably, the first limiting member above the sliding sleeve is positioned near the rear end of the mounting groove, and the first limiting member below the sliding sleeve is positioned near the middle of the mounting groove. This structure rationally distributes the load-bearing positions, improving the control structure's ability to reasonably control the load on the slide rail assembly and enhancing the drawer-type cleaning assembly's pull-out stability.

[0019] Preferably, the outer wall of the drawer-type cleaning assembly is provided with a first sheet metal part arranged near the front end and a second sheet metal part arranged near the rear end. The front and rear ends of the guide rail are respectively locked onto the corresponding first and second sheet metal parts. Two sets of second limiting members are respectively provided on the outer sides of the first and second sheet metal parts. Using the above structure, by setting the guide rail and second limiting members on the sheet metal parts, the wear of the plastic shell of the pull-out cleaning assembly due to vibration is reduced, thereby improving installation reliability and reducing vibration.

[0020] Compared with existing technologies, the advantages of this utility model are as follows: This utility model places the small section for washing small clothes in the middle of the machine, placing the height of the small section within the most comfortable operating space for Asian women. Furthermore, in the drawer-type washing assembly, the bottom of the impeller assembly is shock-absorbingly mounted in the drawer shell using elastic elements. During washing, this effectively buffers the vibration of the impeller assembly, reducing vibration in the small section and lowering overall machine noise. Attached Figure Description

[0027] Figure 7 for Figure 6 Partial sectional view. Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1-7As shown, the multi-zone washing machine of this embodiment includes a frame 4 and an upper drum 1 and a lower drum 2 disposed in the frame 4. A small partition structure is also provided between the upper drum 1 and the lower drum 2. The small partition structure is a drawer-type washing assembly 3 with a top loading port 321. The drawer-type washing assembly 3 includes a drawer shell 301 and a pulsator drum assembly 302 disposed in the drawer shell 301. An elastic element 303 is provided on the inner bottom wall of the drawer shell 301. The bottom of the pulsator drum assembly 302 is disposed in the drawer shell 301 with shock absorption by the elastic element 303.

[0030] With the above structure, the small compartment for washing small clothes is located in the middle of the machine, placing it at a height that is most comfortable for Asian women to operate. Furthermore, in the drawer-type washing assembly, the bottom of the impeller assembly is fitted into the drawer shell with an elastic element for vertical shock absorption. During washing, this effectively cushions the vibration of the impeller assembly, reducing vibration in the small compartment.

[0031] The drawer shell 301 has mounting bosses 304 on both sides, and the elastic elements 303 are springs located at the corners of the mounting bosses 304. The lower middle part of the side wall of the impeller assembly 302 has an outwardly extending support edge 305 that can be supported on the mounting bosses 304 by springs. By adopting the above structure, the shock absorption structure of the small partition is located in the lower middle part of the impeller assembly instead of being located directly at the bottom, which helps to reduce the vibration requirements of the elastic elements on the impeller assembly in terms of height, and further improves the buffering and shock absorption effect.

[0032] In this embodiment, the inner wall of the frame 4 and the outer wall of the drawer-type cleaning component 3 are provided with a guide rail assembly 5 that can guide and cooperate with each other. The inner wall of the frame 4 and the outer wall of the drawer-type cleaning component 3 are provided with a control structure that can cancel the load-bearing and guiding function of the guide rail assembly 5 on the drawer-type cleaning component 3 when the drawer-type cleaning component 3 is pushed in, and restore the load-bearing and guiding function of the guide rail assembly 5 on the drawer-type cleaning component 3 when the drawer-type cleaning component 3 is pulled out.

[0033] With the above structure, the small compartment for washing small clothes is located in the middle of the machine, placing it at a height that is most comfortable for Asian women to operate in. Furthermore, since the drawer-type structure requires the slide rail assembly 5 for pushing, pulling, and load-bearing, and the slide rail assembly 5 has a clearance, when the drawer-type washing component 3 operates at high speed during washing or spin-drying, the resulting vibrations are further amplified by this clearance, causing collision wear on the slide rail assembly 5 and increasing noise. This embodiment includes a control structure that locks the clearance between the slide rail assemblies 5 after the drawer-type washing component 3 is pushed into the machine, canceling the load-bearing function of the slide rail assembly 5 on the drawer-type washing component 3. The control structure then bears the load, allowing the vibrations generated by the drawer-type washing component 3 to be directly transmitted to the machine frame 4 instead of being transmitted through the slide rail assembly 5. When the drawer-type washing component 3 is pulled out, the control structure fails, automatically restoring the load-bearing and guiding function of the slide rail assembly 5 on the drawer-type washing component 3.

[0034] The control structure of this embodiment includes a first limiting member 01 and a second limiting member 02. The first limiting member 01 is disposed on the inner side wall of the frame 4, and the second limiting member 02 is disposed on the outer side wall of the drawer-type cleaning assembly 3. When the drawer-type cleaning assembly 3 is pushed in, the first limiting member 01 and the second limiting member 02 cooperate to achieve upper and lower limiting. When the drawer-type cleaning assembly 3 is pulled out, the first limiting member 01 and the second limiting member 02 disengage. This structure facilitates installation and allows for easy switching between the limiting and disengaging states as the drawer-type cleaning assembly 3 is pushed or pulled out.

[0035] The first limiting member 01 and the second limiting member 02 are interlocked. The first limiting member 01 has a forward-facing socket 011, and correspondingly, the second limiting member 02 has a rearward-facing plug 021. When the drawer-type cleaning assembly 3 is pushed in, the plug 021 is inserted into the socket 011 to form a limiting position. The above structure is a preferred method for the first limiting member 01 and the second limiting member 02 to mutually limit and disengage, and it is simple in structure and convenient for installation and operation.

[0036] The aforementioned slide rail assembly 5 includes a sliding sleeve 51 and a guide rail 52. The sliding sleeve 51 is located on the inner side wall of the frame 4 and extends front to back. The guide rail 52 is located on the outer side wall of the drawer-type cleaning assembly 3, and at least the outer portion is slidably constrained within the sliding sleeve 51. There is a fitting clearance between the sliding sleeve 51 and the guide rail 52. The specific structure of the aforementioned slide rail assembly 5 can adopt existing technology, and will not be described in detail here.

[0037] In this embodiment, when the first limiting member 01 is disengaged from the second limiting member, the sliding sleeve 51 provides load-bearing support for the drawer-type cleaning assembly 3 via the guide rail 52; when the first limiting member 01 is engaged with the second limiting member 02, the first limiting member 01 provides load-bearing support for the drawer-type cleaning assembly 3 via the second limiting member 02, while the clearance between the sliding sleeve 51 and the guide rail 52 remains constant. This structure isolates the slide rail assembly 5 during cleaning, reducing vibration.

[0038] To facilitate assembly, the inner wall of the frame 4 is provided with a front-to-back extending mounting sheet metal 41, and the inner side of the mounting sheet metal 41 is formed with a mounting groove 411 for mounting the slide rail assembly 5 and the control structure.

[0039] In this embodiment, the sliding sleeve 51 is located on the inner wall of the mounting sheet metal 41, the guide rail 52 is located on the outer wall of the drawer-type cleaning assembly 3, and two sets of first limiting members 01 are located on the inner wall of the mounting sheet metal 41, with the two first limiting members 01 located above and below the sliding sleeve 51, respectively. The first limiting member 01 located above the sliding sleeve 51 is arranged near the rear end of the mounting groove 411, and the first limiting member 01 located below the sliding sleeve 51 is arranged near the middle of the mounting groove 411. By adopting the above structure, the load-bearing positions are reasonably distributed to improve the reasonable control of the load-bearing capacity of the guide rail assembly 5 by the control structure, thereby improving the pull-out stability of the drawer-type cleaning assembly 3.

[0040] In this embodiment, the outer wall of the drawer-type cleaning assembly 3 is provided with a first sheet metal part 001 arranged near the front end and a second sheet metal part 002 arranged near the rear end. The front and rear ends of the guide rail 52 are respectively locked onto the corresponding first sheet metal part 001 and second sheet metal part 002. There are two sets of second limiting members 02, which are respectively arranged on the outside of the first sheet metal part 001 and the second sheet metal part 002. By adopting the above structure, the guide rail 52 and the second limiting members 02 are set on the sheet metal parts to reduce the wear of vibration on the plastic shell of the drawer-type cleaning assembly, thereby improving the installation reliability and reducing vibration.

[0041] In this embodiment, the small section for washing small clothes is located in the middle of the machine, so that the height of the small section is within the most comfortable operating space for Asian women. The small section adopts a pull-out drawer-type structure, and after the drawer-type structure is pulled out, the human body's line of sight can completely cover the entire drum, making it convenient to take out clothes.

[0042] In this embodiment, since the drawer-type structure requires the slide rail assembly 5 for pushing, pulling, and load-bearing, and the slide rail assembly 5 has a fitting gap, when the drawer-type cleaning assembly 3 operates at high speed during the cleaning or dehydration process, the resulting vibration will be further transmitted and amplified due to the fitting gap between the slide rail assemblies 5. This will not only cause collision wear to the slide rail assembly 5, but also lead to increased noise. This embodiment is provided with a control structure. After the drawer-type cleaning assembly 3 is pushed into the whole machine, the first limiting member 01 and the second limiting member 02 interlock and limit the sliding, which can lock the fitting gap between the slide rail assemblies 5 and cancel the sliding rail assembly 5's connection to the machine. The drawer-type cleaning assembly 3 is supported by the first limiting member 01 and the second limiting member 02. In this way, the vibration generated by the drawer-type cleaning assembly 3 can be directly transmitted to the whole frame 4 through the first limiting member 01 and the second limiting member 02 instead of being transmitted through the slide rail assembly 5. This avoids collision and wear on the slide rail assembly 5 and effectively reduces noise. When the drawer-type cleaning assembly 3 is pulled out, the first limiting member 01 and the second limiting member 02 disengage relative to each other. The control structure fails and the slide rail assembly 5 automatically restores its load-bearing and guiding function on the drawer-type cleaning assembly 3, making it easy to pull out the drawer-type cleaning assembly 3.

However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings.
