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] CN202310310329.7, "A Multi-Drum Washing Machine," discloses a structure including a first drum, a second drum, and an electric heating system. The electric heating system generates hot airflow, which can be simultaneously or separately delivered to the first drum and / or the second drum. The multi-drum washing machine also includes a first drum and a heat pump system, which generates hot airflow and delivers it to the first drum. This washing machine structure allows for the washing of different types of clothing through multiple drums, meeting users' needs for categorized washing.

[0004] For current multi-drum washing machines, due to higher structural integration and more functional zones, the modular space utilization rate of miniaturized or standard-sized washing machines has increased dramatically, making it more difficult to rationally arrange the vibration damping system within the frame. Especially in small-zone structures, the vibration damping effect is poor due to space constraints, making them prone to colliding with other modules during operation, resulting in high noise levels and a poor user experience. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a multi-zone washing machine that can effectively improve vibration reduction, thereby reducing noise and improving user experience, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A multi-zone washing machine includes a large drum and a first small drum and a second small drum installed in a frame. The first small drum and the second small drum are arranged side by side on the large drum. Anti-vibration interference gaps are reserved between the first small drum and the large drum, and the width of the gaps is 20-25mm. The top and bottom of the first small drum and the second small drum are respectively connected to the frame with a first elastic damping structure. The top and bottom of the large drum are respectively connected to the frame with a second elastic damping structure.

[0008] The above structure provides elastic vibration reduction when each section (large cylinder, first small cylinder, second small cylinder) operates independently or together; at the same time, a specific anti-vibration interference gap is reserved between each section. This gap, while taking into account the utilization rate of the assembly space within the frame, works in conjunction with the first elastic vibration reduction structure and the second elastic vibration reduction structure to avoid vibration interference between the sections.

[0009] Preferably, a first elastic element is connected between the upper side of the first small cylinder and the inner top wall of the frame, and a second elastic element is connected between the upper side of the second small cylinder and the inner top wall of the frame, with both the first and second elastic elements located between the first and second small cylinders. The first and second elastic elements can preferably be suspension springs, with their lower ends hooked to the side of either the first or second small cylinder. An independent sheet metal reinforcing plate is provided at the inner top of the frame, with a crescent-shaped operating opening. The inner edge of this operating opening is bent downwards and extends to hook the upper end of the suspension spring. This structure facilitates connection and provides good connection strength, thereby improving the vibration damping effect.

[0010] Preferably, a first shock absorber is connected between the bottom of the first small cylinder and the first inner sidewall of the frame, and a second shock absorber is connected between the bottom of the second small cylinder and the second inner sidewall of the frame. The first and second shock absorbers are preferably dampers to provide stronger elastic support and cushioning at the bottom of the first and second small cylinders, thereby further improving the vibration reduction effect.

[0011] Preferably, a third elastic element connects the first side of the top of the large cylinder to the first inner wall of the frame, and a fourth elastic element connects the second side of the top of the large cylinder to the second inner wall of the frame. The third and fourth elastic elements can preferably be suspension springs, with their lower ends hooked to the side of the large cylinder. An independent sheet metal reinforcing plate is provided on the inner wall of the frame, with a hook opening for hooking the upper end of the suspension spring. This structure facilitates connection and provides good connection strength, thereby improving the vibration damping effect.

[0012] Preferably, a third shock absorber is connected between the first side of the bottom of the large cylinder and the inner bottom wall of the frame, and a fourth shock absorber is connected between the second side of the bottom of the large cylinder and the inner bottom wall of the frame. The third and fourth shock absorbers can preferably be dampers to provide stronger elastic support and buffering at the bottom of the large cylinder, thereby further improving the vibration reduction effect.

[0013] Of course, the elastic element and vibration damper of this utility model can also adopt other structures that can provide elastic buffering.

[0014] As an improvement, the distance between the center of the large cylinder and the centers of the first and second small cylinders is 370–390 mm. The height of the large cylinder above the ground is 385–400 mm. A gap of 8–12 mm is reserved between the first and second small cylinders and the closest structural component in the frame, and a gap of 13–18 mm is reserved between the large cylinder and the closest structural component in the frame. This structure allows for a more rational spatial arrangement of the large cylinder, the first small cylinder, and the second small cylinder, which, in conjunction with corresponding elastic components and shock absorbers, maximizes the utilization of space within the frame while improving vibration reduction.

[0015] Preferably, a horizontally arranged first sheet metal piece connects the first and second small cylinders, with both sides of the first sheet metal piece being locked to the first and second small cylinders respectively by screws; a vertically arranged second sheet metal piece connects the rear ends of the first and second small cylinders, with both sides of the second sheet metal piece being locked to the rear end faces of the first and second small cylinders respectively by screws. Using the above structure to connect the first and second small cylinders improves the assembly reliability and stability of the small sections within the frame. Furthermore, it balances with the vibration damping structures on both sides of the first and second small cylinders, simplifying the vibration damping structure while improving the vibration damping effect.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This utility model connects the first and second small cylinders to the frame through the first elastic damping structure, and connects the large cylinder to the frame through the second elastic damping structure, so as to provide elastic damping when each section (large cylinder, first small cylinder, and second small cylinder) operates independently or together; at the same time, specific anti-vibration interference gaps are reserved between each section. These gaps, while taking into account the utilization rate of the assembly space within the frame, cooperate with the first and second elastic damping structures to avoid vibration interference between sections, which helps to reduce noise and thus improve the user experience.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-4 As shown, the multi-zone washing machine of this embodiment includes a large drum 3 and a first small drum 1 and a second small drum 2 installed in the frame 4. The first small drum 1 and the second small drum 2 are arranged side by side on the large drum 3. The first small drum 1 and the second small drum 2 are respectively provided with anti-vibration interference gaps 100 between them and the large drum 3. The width of the gap 100 is 20-25mm. The top and bottom of the first small drum 1 and the second small drum 2 are respectively connected to the frame 4 with a first elastic damping structure. The top and bottom of the large drum 3 are respectively connected to the frame 4 with a second elastic damping structure.

[0023] The above structure provides elastic vibration reduction when each section (large cylinder 3, first small cylinder 1, second small cylinder 2) operates independently or together; at the same time, a specific anti-vibration interference gap 100 is reserved between each section. This gap 100, while taking into account the utilization rate of the assembly space within the frame 4, works in conjunction with the first elastic vibration reduction structure and the second elastic vibration reduction structure to avoid vibration interference between each section.

[0024] A first elastic element 01 is connected between the upper side of the first small cylinder 1 and the inner top wall of the frame 4, and a second elastic element 02 is connected between the upper side of the second small cylinder 2 and the inner top wall of the frame 4. Both the first elastic element 01 and the second elastic element 02 are located between the first small cylinder 1 and the second small cylinder 2. The first elastic element 01 and the second elastic element 02 can preferably be suspension springs. The lower end of the suspension spring is hung and connected to the side of the first small cylinder 1 or the second small cylinder 2. An independent sheet metal reinforcing plate is provided on the inner top of the frame 4. A crescent-shaped operating opening is provided on the sheet metal reinforcing plate. The inner edge of the operating opening is bent downward and extended to hang the upper end of the suspension spring. This structure facilitates connection and has good connection strength, thereby improving the vibration reduction effect.

[0025] A first shock absorber 001 is connected between the bottom of the first small cylinder 1 and the first inner wall of the frame 4, and a second shock absorber 002 is connected between the bottom of the second small cylinder 2 and the second inner wall of the frame 4. The first shock absorber 001 and the second shock absorber 002 are preferably dampers to provide stronger elastic support and cushioning at the bottom of the first small cylinder 1 and the second small cylinder 2, thereby further improving the vibration reduction effect.

[0026] A third elastic element 03 connects the first side of the top of the large cylinder 3 to the first inner wall of the frame 4, and a fourth elastic element 04 connects the second side of the top of the large cylinder 3 to the second inner wall of the frame 4. The aforementioned third elastic element 03 and fourth elastic element 04 can preferably be suspension springs, with their lower ends hooked to the side of the large cylinder 3. An independent sheet metal reinforcing plate is provided on the inner wall of the frame 4, with a hook opening for hooking to the upper end of the suspension spring. This structure facilitates connection and provides good connection strength, thereby improving the vibration damping effect.

[0027] A third shock absorber 003 is connected between the first side of the bottom of the main cylinder 3 and the inner bottom wall of the frame 4, and a fourth shock absorber 004 is connected between the second side of the bottom of the main cylinder 3 and the inner bottom wall of the frame 4. The third shock absorber 003 and the fourth shock absorber 004 can preferably be dampers to provide stronger elastic support and buffering at the bottom of the main cylinder 3, thereby further improving the vibration reduction effect.

[0028] Of course, the elastic element and vibration damper in this embodiment can also be other structures that can provide elastic buffering.

[0029] In this embodiment, the distance between the center of the large cylinder 3 and the centers of the first small cylinder 1 and the second small cylinder 2 is 370-390mm. The height of the large cylinder 3 above the ground is 385-400mm. A gap of 8-12mm is reserved between the first small cylinder 1, the second small cylinder 2 and the closest structural component of the frame 4, and a gap of 13-18mm is reserved between the large cylinder 3 and the closest structural component of the frame 4. Using the above structure, the large cylinder 3, the first small cylinder 1, and the second small cylinder 2 are arranged more rationally in space, and in conjunction with the corresponding elastic components and shock absorbers, the vibration reduction effect is improved while maximizing the utilization of space within the frame 4.

[0030] A horizontally arranged first sheet metal part 10 connects the first small cylinder 1 and the second small cylinder 2. Both sides of the first sheet metal part 10 are respectively locked to the first small cylinder 1 and the second small cylinder 2 with screws. A vertically arranged second sheet metal part 20 connects the rear ends of the first small cylinder 1 and the second small cylinder 2. Both sides of the second sheet metal part 20 are respectively locked to the rear end faces of the first small cylinder 1 and the second small cylinder 2 with screws. This structure improves the assembly reliability and stability of the small sections within the frame 4. Furthermore, it balances with the vibration damping structures on both sides of the first small cylinder 1 and the second small cylinder 2, simplifying the vibration damping structure while improving the vibration damping effect.

[0031] In this embodiment, the first small cylinder 1 and the second small cylinder 2 are connected to the frame 4 through the first elastic vibration damping structure, and the large cylinder 3 is connected to the frame 4 through the second elastic vibration damping structure, so as to provide elastic vibration damping when each section (large cylinder 3, first small cylinder 1, and second small cylinder 2) operates independently or together; at the same time, a specific anti-vibration interference gap 100 is reserved between each section. This gap 100, while taking into account the utilization rate of the assembly space within the frame 4, works in conjunction with the first elastic vibration damping structure and the second elastic vibration damping structure to avoid vibration interference between each section, which helps to reduce noise and thus improve the user experience.
