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 comprising a first drum, a second drum, and an electric heating system. The electric heating system is capable of generating 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 is capable of generating hot airflow and delivering the hot airflow to the first drum.

[0004] The washing machine with the above structure can wash different types of clothes through multiple drums to meet the user's needs for categorized washing. However, for each small section drum, in order to achieve uniform airflow to each drum, an independent drying system is used during drying, resulting in a complex overall structure and high cost. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a multi-zone washing machine that can share a single drying system, thereby simplifying the structure, reducing costs, and ensuring uniform airflow distribution, 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 first washing drum, a second washing drum, and a drying assembly. The drying assembly includes an air duct, a first air guide duct, and a second air guide duct. A first end of the air duct is a gas input end, and a second end is connected to the first air guide duct and the second air guide duct. The air outlet end of the first air guide duct is connected to the first washing drum, and the air outlet end of the second air guide duct is connected to the second washing drum. The air duct is provided with a guide plate that can split the incoming air into flow channels corresponding to the first air guide duct and the second air guide duct respectively.

[0008] With the above structure, the two washing drums share a set of drying components, which simplifies the overall structure and reduces costs. In order to make the airflow into the two washing drums uniform, a guide plate is set in the drying component. The guide plate divides the gas in the air duct and sends it to the corresponding washing drum through the first air duct and the second air duct respectively, so as to ensure the balanced distribution of airflow.

[0009] Preferably, the connection between the air duct and the first and second air guide ducts forms a Y-shaped structure, and the end of the guide plate is arranged corresponding to the tip of the center of the Y-shaped structure, thereby dividing the air duct into a first region corresponding to the first air guide duct and a second region corresponding to the second air guide duct. This structure facilitates the balanced distribution of airflow within the air duct.

[0010] Preferably, the air duct has an L-shaped structure. The vertical portion of the L-shaped structure connects with the first and second air guide ducts to form a Y-shaped structure. The horizontal portion of the L-shaped structure is located beside the first air guide duct. The guide plate extends from the horizontal portion of the L-shaped structure through a circular arc bend to the vertical portion. This structure allows for full utilization of the washing machine's installation space.

[0011] Preferably, the bend in the L-shaped structure is smoothly transitioned through an outer arc-shaped sidewall, which connects to the outer sidewall of the second air guide duct. This structure facilitates smooth airflow guidance at the duct bend, preventing airflow collisions that could increase wind resistance.

[0012] Preferably, after the first and second air guide ducts are connected, they correspond to the V-shaped portion of the upper part of the Y-shaped structure. The connection between the first and second air guide ducts smoothly transitions to form a circular arc guide surface arranged in the center of the vertical portion of the Y-shaped structure. Using this structure, the separated airflow can be smoothly guided at the connection between the first and second air guide ducts, reducing airflow collisions.

[0013] Preferably, the end of the guide plate is located within the vertical portion of the L-shaped structure and is arranged corresponding to the arc-shaped guide surface. This structure further reduces airflow collision at the junction of the first and second air ducts.

[0014] As an improvement, the guide plate divides the air duct into a first region corresponding to the first guide duct and a second region corresponding to the second guide duct, wherein the cross-sectional width of the first region is greater than the cross-sectional width of the second region. The width ratio is preferably 2:1. The length of the guide plate within the vertical portion of the L-shaped structure is less than the length of that vertical portion. Because the air duct adopts a bent L-shaped structure, the airflow switches from horizontal to vertical transport when passing through the bend. Due to transport inertia, the airflow will partially deflect and disperse towards the second guide duct at the outlet. Therefore, the flow-dividing cross-section corresponding to the first guide duct is enlarged to compensate for the airflow inertia that deflects towards the second guide duct, so that the airflow sent to the first and second guide ducts is more evenly distributed.

[0015] Preferably, the drying assembly further includes a heating element disposed in the transverse portion of the air duct, with the starting end of the guide plate located downstream of the heating element and arranged corresponding to the middle portion of the heating element. This structure allows for the distribution of the heated gas.

[0016] Preferably, the cross-sectional area at the intersection of the air duct and the first and second air guide ducts gradually decreases along the airflow direction. The sidewalls at the intersection of the air duct and the first and second air guide ducts gradually converge along the airflow direction to form a guide slope. This structure can increase the airflow velocity sent into the washing drum, which is beneficial to improving drying efficiency.

[0017] The washing machine of this utility model also includes a first drum and a second drum arranged vertically at intervals. The first washing drum and the second washing drum are arranged horizontally side by side between the first drum and the second drum. The drying component is disposed in the space above the first washing drum and the second washing drum and below the first drum. With the above structure, different types of clothes can be washed through multiple drums to meet the user's needs for more classified washing. Furthermore, the arrangement of each component can make full use of the installation space of the washing machine.

[0018] Compared with the prior art, the advantages of this utility model are as follows: This utility model sets up a first washing drum and a second washing drum as washing compartments, which can wash different types of clothes to meet the user's needs for classified washing; the two washing drums share a set of drying components, which simplifies the overall structure and reduces costs; in order to make the airflow into the two washing drums uniform, a guide plate is set in the drying component. The guide plate divides the air in the air duct and sends it to the corresponding washing drum through the first air duct and the second air duct respectively, so as to ensure the balanced distribution of airflow and improve the drying effect.

[0021] Figure 3 for Figure 2 Partial sectional view. Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-3As shown, the multi-zone washing machine of this embodiment includes a first washing drum 1, a second washing drum 2, and a drying assembly 3. The drying assembly 3 includes an air duct 33, a first air guide duct 31, and a second air guide duct 32. The first end of the air duct 33 is a gas input end, and the second end is connected to the first air guide duct 31 and the second air guide duct 32. The air outlet end of the first air guide duct 31 is connected to the first washing drum 1, and the air outlet end of the second air guide duct 32 is connected to the second washing drum 2. The air duct 33 is provided with a guide plate 34 that can divide the incoming air into flow directions corresponding to the first air guide duct 31 and the second air guide duct 32 respectively.

[0024] With the above structure, the two washing drums share a set of drying components 3, which simplifies the overall structure and reduces costs. In order to make the airflow into the two washing drums uniform, a guide plate 34 is set in the drying component 3. The guide plate 34 divides the gas in the air duct 33 and sends it to the corresponding washing drums through the first air duct 31 and the second air duct 32 respectively, so as to ensure the balanced distribution of airflow.

[0025] The connection between the air duct 33 and the first air guide duct 31 and the second air guide duct 32 forms a Y-shaped structure. The end of the guide plate 34 is arranged corresponding to the tip of the center of the Y-shaped structure, thereby dividing the air duct 33 into a first region 331 corresponding to the first air guide duct 31 and a second region 332 corresponding to the second air guide duct 32. The above structure is beneficial for the balanced distribution of air in the air duct 33.

[0026] The air duct 33 has an L-shaped structure. The vertical part of this L-shaped structure connects with the first air guide duct 31 and the second air guide duct 32 to form a Y-shaped structure. The horizontal part of this L-shaped structure is located beside the first air guide duct 31. The guide plate 34 extends from the horizontal part of the L-shaped structure through an arc bend to the vertical part. By adopting the above structure, the installation space of the washing machine can be fully utilized.

[0027] The L-shaped structure's bends are smoothly transitioned by an outer arc-shaped sidewall 333, which connects to the outer sidewall of the second air guide duct 32. The guide plate 34 is an arc-shaped structure that matches the outer arc-shaped sidewall 333. This structure facilitates smooth airflow guidance at duct bends, preventing airflow collisions that could increase wind resistance.

[0028] After the first air guide duct 31 and the second air guide duct 32 are connected, they correspond to the V-shaped portion of the upper part of the Y-shaped structure. The connection between the first air guide duct 31 and the second air guide duct 32 smoothly transitions to form an arc-shaped guide surface 35 arranged in the center of the vertical portion of the Y-shaped structure. With the above structure, the separated airflow can be smoothly guided at the connection between the first air guide duct 31 and the second air guide duct 32, reducing airflow collision.

[0029] The end of the guide vane 34 is located within the vertical portion of the L-shaped structure and is arranged corresponding to the arc-shaped guide surface 35. This structure further reduces airflow collision at the junction of the first guide duct 31 and the second guide duct 32.

[0030] In this embodiment, the guide plate 34 divides the air duct 33 into a first region 331 corresponding to the first guide duct 31 and a second region 332 corresponding to the second guide duct 32. The cross-sectional width of the first region 331 is greater than the cross-sectional width of the second region 332. The width ratio is preferably 2:1. The length of the guide plate 34 within the vertical portion of the L-shaped structure is less than the length of that vertical portion. Since the air duct 33 adopts a bent L-shaped structure, the airflow switches from horizontal to vertical transport when passing through the bend. Due to transport inertia, the airflow will partially deflect and disperse towards the second guide duct 32 at the outlet. Therefore, the flow-dividing cross-section corresponding to the first guide duct 31 is enlarged to compensate for the airflow inertia that deflects towards the second guide duct 32, so that the airflow sent to the first guide duct 31 and the second guide duct 32 is more evenly distributed.

[0031] The drying assembly 3 also includes a heating element 37 disposed in the transverse portion of the air duct 33, with the starting end of the guide plate 34 located downstream of the heating element 37 and arranged corresponding to the middle of the heating element 37. A fan 38 is connected to the inlet end of the air duct 33. With this structure, the heated gas can be distributed.

[0032] The cross-sectional area at the intersection of air duct 33 with the first air guide duct 31 and the second air guide duct 32 gradually decreases along the airflow direction. The sidewalls at the intersection of air duct 33 with the first air guide duct 31 and the second air guide duct 32 gradually converge along the airflow direction to form a guide slope 100. This structure can increase the airflow velocity sent into the washing drum, which is beneficial to improving drying efficiency.

[0033] The washing machine in this embodiment also includes a first drum 01 and a second drum 02 arranged vertically at intervals, a first washing tub 1 and a second washing tub 2 arranged horizontally side by side between the first drum 01 and the second drum 02, and a drying assembly 3 disposed in the space above the first washing tub 1 and the second washing tub 2 and below the first drum 01. With the above structure, different types of clothes can be washed through multiple tubs to meet the user's needs for more categorized washing, and the arrangement of each component can make full use of the washing machine's installation space.

[0034] In this embodiment, a first washing drum 1 and a second washing drum 2 are set as washing zones, which can wash different types of clothes to meet the user's needs for classified washing. The two washing drums share a set of drying components 3, which simplifies the overall structure and reduces costs. In order to make the airflow into the two washing drums uniform, a guide plate 34 is set in the drying component 3. The guide plate 34 divides the gas in the air duct 33 and sends it to the corresponding washing drum through the first air duct 31 and the second air duct 32 respectively, so as to ensure the balanced distribution of airflow and improve the drying effect.
