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 multi-drum washing machines, each drum is connected to the machine frame via an elastic shock-absorbing structure. The air duct of the lower drum is usually located at its top and sandwiched between the upper and lower drums, which further reduces the assembly gap. The drums have a significant weight difference between washing and spin-drying states. This makes it difficult for a specific elastic shock-absorbing structure to accommodate the vibration amplitude in both states simultaneously. Specifically, the upper drum is heavier during washing, while the lower drum vibrates more during spin-drying. When both are in use simultaneously, if the deformation of the elastic shock-absorbing structure is too small, it will not meet the shock absorption requirements; if the deformation is too large, collisions may occur, affecting usability. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a multi-zone washing machine that can take into account both shockproof and collision-proof effects under different usage conditions, 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. The top of the large drum is provided with an air guide duct for guiding air into the large drum. The air guide duct extends back and forth and is offset to the side of either the small drum or the large drum, thereby reserving a shock-absorbing gap below the first small drum and the second small drum and above the large drum. The air guide duct is constrained together with the large drum.

[0008] The aforementioned large drum, first small drum, and second small drum provide multiple washing zones, allowing for the washing of different types of clothing to meet users' needs for categorized washing. Due to the multi-zone arrangement, the assembly space between the first small drum, second small drum, and large drum is limited. This invention addresses this by offsetting the air duct of the large drum, thereby reserving more shock-absorbing gaps between the small and large drums. Furthermore, it constrains the air duct to the large drum, ensuring that the large and small drums provide both shock absorption and collision protection under different usage conditions when the large drum vibrates. The air duct moves synchronously with the large drum, avoiding vibration interference between the air duct and the large drum.

[0009] Preferably, the frame is equipped with a fan connected to the air duct, and the rear end of the air duct is telescopically connected to the rear end of the fan. The fan, as a power component, is usually fixedly installed in the frame, while the air duct needs to move synchronously with the main cylinder when it vibrates. This invention uses a telescopic structure to connect the air duct and the fan to eliminate vibration interference.

[0010] Preferably, the air guide duct is flat and arranged close to the outer wall of the main cylinder, and the rear end of the air guide duct extends upward and is connected to a corrugated pipe that is connected to the fan. The use of a corrugated pipe allows for simple structural adaptation to the vibration amplitude of the air guide duct.

[0011] Preferably, the fan is vertically arranged behind the first or second small cylinder and close to the side wall of the frame, and a downward-extending air duct is formed at the rear end of the fan, the lower end of which is connected to the upper end of the corrugated pipe. This structure shortens the air guiding distance and reduces wind resistance.

[0012] To facilitate installation and assembly, the frame is provided with a support plate located after the first and second small cylinders and above the air guide duct. The fan is mounted on the support plate, and the fan's air duct extends downwards around the rear side of the support plate.

[0013] Preferably, the outer side of the main cylinder is provided with an upwardly extending connecting post. Correspondingly, the side edge of the air guide duct is provided with a lug plate that can abut against the upper end of the connecting post. The lug plate and the connecting post are respectively provided with connecting holes for screws to pass through and lock the two together. With this structure, the main cylinder and the air guide duct are locked together, which is convenient for assembly and has good connection reliability.

[0014] Preferably, the shock-absorbing gap is 35-50mm. In existing technology, the small and large drums are separated for shock absorption, with an air duct sandwiched between them. The duct and frame are connected. When the small drum is full of water for washing, its top suspension spring is stretched, causing the small drum to sink. Typically, if a suspension spring of 3N / mm is used, the two small drums will sink 22mm when full of water for washing. However, the distance between the air duct and the small drum is only 12mm, making it easy for the small drum to collide with the lower air duct, generating noise. In severe cases, this can damage the air duct and the outer drum's plastic components, leading to safety issues. This invention moves the air duct downwards and rigidly connects it to the large drum. The shock-absorbing gap between the small drum and the air duct increases to 40mm. When both small drums are full of washing water, the 40mm gap is much larger than the 22mm sinking of the small drum. When the large drum is spinning, the gap between the air duct and the small drum is also much larger than the amplitude of the large drum's vibration.

[0015] Preferably, the frame also includes a second large cylinder positioned above the first and second small cylinders. This structure can meet the user's need for more partitioned cleaning and is easy to use.

[0016] Compared with the prior art, the advantages of this utility model are as follows: The large drum, the first small drum, and the second small drum of this utility model can provide multiple washing areas, thereby washing different types of clothes to meet the user's needs for classified washing; Due to the multi-zone arrangement, the assembly space between the first small drum, the second small drum, and the large drum is limited. This utility model, on the one hand, offsets the air guide duct of the large drum, thereby reserving more shockproof gaps between the small drum and the large drum; on the other hand, it constrains the air guide duct with the large drum, so that when the large drum vibrates, the large drum and the small drum can take into account both shockproof and collision-proof effects under different usage states; The air guide duct moves synchronously with the large drum, avoiding vibration interference between the air guide duct and the large drum.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3As shown, the multi-zone washing machine of this embodiment includes a large drum 10 and a first small drum 01 and a second small drum 02 installed in the frame 1. The first small drum 01 and the second small drum 02 are arranged side by side on the large drum 10. The top of the large drum 10 is provided with an air guide pipe 2 for guiding air to the large drum 10. The air guide pipe 2 extends back and forth and is offset to the side of any small drum and the large drum 10, so as to reserve a shockproof gap 3 below the first small drum 01 and the second small drum 02 and above the large drum 10. The air guide pipe 2 is constrained together with the large drum 10.

[0022] The aforementioned large drum 10, first small drum 01, and second small drum 02 can provide multiple washing zones, thereby washing different types of clothes to meet the user's needs for classified washing. Due to the multi-zone arrangement, the assembly space between the first small drum 01, second small drum 02 and the large drum 10 is limited. In this embodiment, on the one hand, the air guide duct 2 of the large drum 10 is offset, thereby reserving more anti-vibration gaps 3 between the small drums and the large drum 10. On the other hand, the air guide duct 2 is constrained to the large drum 10, so that when the large drum 10 vibrates, the large drum 10 and the small drum can take into account both shock absorption and anti-collision effects under different usage states. The air guide duct 2 moves synchronously with the large drum 10, avoiding vibration interference between the air guide duct 2 and the large drum 10.

[0023] A fan 4 connected to the air duct 2 is installed in the frame 1. The rear end of the air duct 2 is telescopically connected to the rear end of the fan 4. The fan 4, as a power component, is usually fixedly installed in the frame 1, while the air duct 2 needs to move synchronously with the main cylinder 10 when it vibrates. In this embodiment, the air duct 2 and the fan 4 are connected by a telescopic structure to eliminate vibration interference.

[0024] The air duct 2 is flat and close to the outer wall of the main cylinder 10. The rear end of the air duct 2 extends upward and is connected to a corrugated pipe 5 that is connected to the fan 4. The corrugated pipe 5 is used to achieve the adaptation of the vibration amplitude of the air duct 2 with a simple structure.

[0025] The fan 4 is vertically arranged behind the first small tube 01 or the second small tube 02 and close to the side wall of the frame 1. The rear end of the fan 4 forms a downward-extending air duct 41, the lower end of which is connected to the upper end of the corrugated pipe 5. This structure is adopted to shorten the air guiding distance and reduce wind resistance.

[0026] To facilitate installation and assembly, a support plate is provided in the frame 1, located after the first small cylinder 01 and the second small cylinder 02 and above the air guide duct 2. The fan 4 is located on the support plate, and the air duct 41 of the fan 4 extends downward around the rear side of the support plate.

[0027] The outer side of the main duct 10 is provided with an upwardly extending connecting post 101. Correspondingly, the side edge of the air duct 2 is provided with a lug 21 that can abut against the upper end of the connecting post 101. The lug 21 and the connecting post 101 are respectively provided with connecting holes for screws to pass through and lock the two together. With this structure, the main duct 10 and the air duct 2 are locked together, which is convenient for assembly and has good connection reliability.

[0028] The shock-absorbing gap 3 is 35-50mm. In existing technology, the small and large drums 10 are separated for shock absorption, with an air duct 2 sandwiched between them. The air duct 41 and frame 1 are connected. When the small drum is full of water for washing, the suspension spring at its top is stretched, causing the small drum to sink. Typically, if the suspension spring is 3N / mm, the two small drums will sink 22mm when full of water for washing. However, the distance between the air duct 2 and the small drum is only 12mm. The small drum is prone to colliding with the air duct 2 below, generating noise. In severe cases, the air duct 2 and the plastic parts of the outer drum may be damaged, causing safety problems. In this embodiment, the air duct 2 is moved down and rigidly connected to the large drum 10. The shock-absorbing gap 3 between the small drum and the air duct 2 is increased to 40mm. When the two small drums are full of washing water, the 40mm gap is much larger than the sinking amount of the small drum 22mm. When the large drum 10 is spinning, the gap between the air duct 2 and the small drum is also much larger than the amplitude of the large drum 10.

[0029] The frame 1 also houses a second large cylinder 20, located above the first small cylinder 01 and the second small cylinder 02. This structure can meet the user's needs for more zoned cleaning and is easy to use.

[0030] In this embodiment, the large drum 10, the first small drum 01, and the second small drum 02 can provide multiple washing zones to wash different types of clothes, thus meeting the user's needs for classified washing. Due to the multi-zone arrangement, the assembly space between the first small drum 01, the second small drum 02, and the large drum 10 is limited. In this embodiment, on the one hand, the air guide duct 2 of the large drum 10 is offset, thereby reserving more anti-vibration gaps 3 between the small drums and the large drum 10. On the other hand, the air guide duct 2 is constrained to the large drum 10, so that when the large drum 10 vibrates, the large drum 10 and the small drum can take into account both shock absorption and collision prevention effects under different usage states. The air guide duct 2 moves synchronously with the large drum 10, avoiding vibration interference between the air guide duct 2 and the large drum 10.

[0031] The washing machine in this embodiment can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the washing machine to perform corresponding operations, thereby realizing intelligent control of the washing machine and improving the user experience.
