Description

Technical Field

[0001] The utility model relates to the technical field of clothing treatment equipment, in particular to an automatic dosing system with a stirring and mixing function and a washing machine. Background Art

[0002] In modern family life, the washing machine has become one of the indispensable household appliances, and its washing effect directly affects the cleanliness and wearing comfort of clothes. In order to improve the washing efficiency, the use of detergent becomes particularly crucial. Traditional washing machines usually rely on users to manually add detergent. This method is not only cumbersome to operate, but also difficult to accurately control the dosage of detergent, often resulting in poor washing effect or detergent waste.

[0003] With the development of technology, the technology of automatically dosing detergent has been gradually applied to washing machines to solve the deficiencies of manual addition. Most of the existing automatic dosing systems adopt the pump type or the Venturi tube negative pressure method to extract liquid detergent or washing powder from the liquid storage box and dose it into the washing tub regularly and quantitatively. These systems have realized the automatic dosing of detergent to a certain extent and improved the convenience and efficiency of washing.

[0004] However, there are still some problems in the actual application of the existing technology. First of all, the detergent is often not fully mixed with water during the dosing process, resulting in uneven distribution of the washing supplies in the washing tub and affecting the washing effect. Especially when using washing powder, due to the large particle size of the washing powder and its difficulty in dissolving in water, the situation of uneven mixing is more likely to occur. Secondly, most of the existing automatic dosing systems lack a stirring device and cannot effectively stir and mix the detergent and water, resulting in a reduced utilization rate of the washing supplies and an unsatisfactory washing effect.

[0005] In addition, some existing automatic dosing systems have tried to set up a stirring device. For example, a Chinese patent with the publication number CN115538113A discloses a dispenser, a detergent dosing device, and a washing device. The dispenser includes a dispenser box and a stirring mechanism. The dispenser box is provided with a water inlet chamber, a first detergent dosing chamber for accumulating detergent and capable of receiving the incoming water flow, and a drainage channel for discharging the liquid in the first detergent dosing chamber. The stirring mechanism includes a driving member disposed on the water flow path in the water inlet chamber and a stirring member disposed in the first detergent dosing chamber. The driving member can rotate under the impact of the water flow and drive the stirring member to rotate. During the process of the stirring member stirring the detergent in the first detergent dosing chamber, the water inlet chamber normally injects washing water into the cylinder assembly, so that the detergent can be fully and effectively dissolved and foamed in the first detergent dosing chamber, which can improve the washing effect of the washing device. However, due to unreasonable structural design, the stirring effect is limited and faults are prone to occur. For example, the sealing performance between the stirring device and the detergent box is poor, resulting in the failure of the water seal, which in turn affects the normal operation of the stirring device. At the same time, the cooperation between the driving motor of the stirring device and the bearing is not tight enough, and problems such as poor rotation or excessive wear are likely to occur, shortening the service life of the device.

[0035] Such as Figures 1 to 6As shown in the figure, the present application discloses an automatic dosing system with a stirring and mixing function, including a detergent box assembly 1. The detergent box assembly 1 includes a detergent box 15 and a detergent box cover assembly 3. The detergent box cover assembly 3 is detachably connected to the detergent box 15. A water passage 6 is provided on the detergent box cover assembly 3. A temporary water storage chamber 14 is provided at the bottom of the detergent box 15 away from the detergent box cover assembly 3. The washing supplies are conveyed into the water passage 6 and flow towards the temporary water storage chamber 14. A stirring impeller assembly 10 is provided in the temporary water storage chamber 14. The stirring impeller assembly 10 can mix and stir the washing supply mixture in the temporary water storage chamber 14 and then flow through the second drain port 13 into the washing tub.

[0036] The automatic dosing system with a stirring and mixing function disclosed in the present application, by providing a detachably connected detergent box 15 and a detergent box cover assembly 3, and by providing a water passage 6 on the detergent box cover assembly 3, the washing supplies, especially liquid washing supplies, can be accurately conveyed into the water passage 6 through an efficient automatic dosing mechanism, such as piston pump liquid extraction or Venturi negative pressure method, and further flow into the temporary water storage chamber 14 at the bottom of the detergent box 15. The stirring impeller assembly 10 in the temporary water storage chamber 14 is started to work. Through its unique stirring design, the assembly can quickly and fully mix the washing supplies with water to form delicate foam, and then enter the washing tub of the washing machine through the second drain port 13 on the detergent box 15. This mixing process ensures that the washing supplies have been fully integrated with water, which can greatly improve the washing effect.

[0037] For the automatic dosing system with a stirring and mixing function described in the present application, by providing a temporary water storage chamber 14 at the bottom of the detergent box 15 and introducing a stirring impeller assembly 10 therein, the washing supplies are fully stirred in the temporary water storage chamber 14 to form uniform foam, and then enter the washing tub through the second drain port 13 of the detergent box, ensuring the full utilization of the washing supplies during the washing process, significantly improving the washing efficiency and cleanliness, having a compact structure, being convenient for daily cleaning and maintenance, extending the service life of the system, and enhancing the user experience.

[0038] As a preferred example of the present application, the stirring impeller assembly 10 includes a stirring impeller 20 and a driving device 16. The driving device 16 is arranged outside the detergent box 15, and the stirring impeller 20 is arranged in the temporary water storage chamber 14 and can stir the mixed liquid inside it under the driving action of the driving device 16. As a specific example of the present application, a bearing fixing device 17 is arranged in the temporary water storage chamber 14, a first bearing 18 is installed on the bearing fixing device 17, and the stirring impeller 20 with spiral blades passes through the first bearing 18. A driving device 16 is installed outside the detergent box 15, and the output shaft of the driving device 16 is fixedly connected to the stirring impeller 20 and is rotationally matched with the first bearing 18. By optimizing and improving the stirring impeller assembly 10 in the present application, the driving device 16 is cleverly arranged outside the detergent box 15, while the stirring impeller 20 is located in the temporary water storage chamber 14, realizing sufficient stirring of the mixture of the washing supplies and water, ensuring complete dissolution of the washing supplies, and thus significantly improving the washing effect. At the same time, through the clever combination of the driving device 16 and the stirring impeller 20 with the bearing fixing device 17 and the first bearing 18, the stable operation of the stirring impeller is ensured, the stability and durability of the system are improved, and the stirring process is made more efficient and uniform.

[0039] As a preferred example of the present application, a water seal 19 is provided at the connection between the stirring impeller 20 and the side wall of the detergent box 15 and / or at the connection between the output shaft of the driving device 16 and the side wall of the detergent box 15. In the example of the present application, the water seal 19 is arranged at the rotational connection between the output shaft of the driving device 16 and the first bearing 18 inside the detergent box 15. While ensuring the reliable stirring of the driving device 16 driving the stirring impeller 20 inside the temporary water storage chamber 14, it avoids system failures and a decline in the washing effect caused by the leakage of the mixed solution from the connection, improves the user experience, and makes the washing process more reassuring and worry-free.

[0040] As a preferred example of the present application, a space for accommodating the liquid storage box assembly 2 is formed between the detergent box 15 and the detergent box cover assembly 3. The liquid storage box assembly 2 can be pulled out or pushed into the detergent box 15. A first feeding cavity 12 is provided on the liquid storage box assembly 2, and the first feeding cavity 12 is communicated with the water passing channel 6 and the temporary water storage chamber 14. In the example of the present application, the space between the detergent box 15 and the detergent box cover assembly 3 constitutes an outer shell space for the liquid storage box assembly 2 to be pulled out or pushed into. The liquid washing supplies sucked by the detergent box cover assembly 3 under the action of the automatic feeding function module 4 pass through the water channel 6 and are fed into the first feeding cavity 12, or the washing supplies in powder form are fed into the first feeding cavity 12 and then flow to the temporary water storage chamber 14 after mixing.

[0041] This setting further optimizes the structure of the liquid storage box assembly 2. During the actual working process, under the action of the automatic dosing function module 4, the detergent box cover assembly 3 can accurately suck the liquid detergent and discharge it through the water channel 6 into the first dosing chamber 12. For solid detergents such as washing powder, they can also be directly discharged into the first dosing chamber 12, and after mixing with water, flow to the temporary water storage chamber 14, thereby realizing the efficient utilization of the detergents, ensuring the smooth circulation and full mixing of the detergents, and further improving the washing effect.

[0042] Preferably, the bottom wall of the first dosing chamber 12 is inclined downward along the reverse direction of the pulling movement of the liquid storage box assembly 2. This setting further optimizes the design of the first dosing chamber 12 in the liquid storage box assembly 2. The bottom wall of the first dosing chamber 12 is inclined, which not only ensures the smooth flow and complete discharge of the detergents, avoids the backflow or accumulation of the mixed solution, but also improves the mixing efficiency and uniformity of the detergents and water, and further enhances the washing effect of the automatic dosing system with stirring and mixing function described in this application.

[0043] As a preferred example of this application, a liquid storage box water channel 11 is provided on the liquid storage box assembly 2. One end of the liquid storage box water channel 11 is connected to the lowest point of the bottom wall of the first dosing chamber 12, and the other end leads to the temporary water storage chamber 14 through the first water outlet 9. As a specific example of this application, the liquid storage box water channel 11 is arranged at the rear end in the pulling direction. The liquid storage box water channel 11 is arranged horizontally or inclined downward from the side close to the first dosing chamber 12 to the side away from the first dosing chamber 12, so that the mixed liquid of the mixed detergents in the first dosing chamber 12 is pre-dissolved and mixed in the liquid storage box water channel 11, further improving the dissolution efficiency and mixing uniformity of the detergents.

[0044] Preferably, the driving device 16 is arranged outside the side wall of the detergent box 15 at the rear end in the pulling movement direction of the liquid storage box assembly 2. The axis of the stirring impeller 20 is arranged parallel to the pulling movement direction of the liquid storage box assembly 2, or the central axis of the stirring impeller 20 forms an angle less than 45° with the opposite horizontal plane. In the example of this application, the axis of the stirring impeller 20 is arranged along the length direction of the detergent box 15 as a whole.

[0045] This setting further optimizes the setting structure of the stirring impeller 20, so that the stirring impeller 20 can stir the mixed liquid more smoothly during rotation, improving the stirring efficiency and uniformity, bringing a better quality and more efficient washing experience to users, with a compact structure, optimizing the space layout, saving space, and also improving the stability and reliability of the system.

[0046] As some other examples of this application, such as Figures 5 to 6As shown, the axis of the stirring impeller 20 is set perpendicular to the direction of the extraction movement of the liquid storage box assembly 2, or the included angle between the central axis of the stirring impeller 20 and the vertical plane of the ground is less than 45°. In the example of the present application, the axis of the stirring impeller 20 is integrally arranged along the vertical direction of the detergent box 15 (the vertical direction is the direction perpendicular to the extraction movement direction of the liquid storage box assembly 2).

[0047] As a preferred example of the present application, a water inlet 5 is provided on the detergent box cover assembly 3. The water inlet 5 is communicated with the water passing channel 6. A water spraying sink 7 is arranged at the rear end of the water passing channel 6. A plurality of water spraying ports 8 are arranged on the water spraying sink 7. The water spraying ports 8 are used to spray the mixed liquid in the water passing channel 6 into the first feeding cavity 12. This setting further optimizes the structure of the detergent box cover assembly 3. By providing the water inlet 5 on the detergent box cover assembly 3 and connecting it with the water inlet valve, the inlet water flow can flow into the interior of the water passing channel 6. At the same time, during washing, through a liquid pumping pump such as a piston pump or a Venturi tube negative pressure method, the washing supplies are pumped into the water passing channel 6 for mixing and then flow to the water spraying sink 7. At the position of the water spraying sink 7, a plurality of water spraying ports 8 are ingeniously arranged to ensure that the water flow can be sprayed evenly and powerfully, so that the liquid washing supplies pre-dissolved in the water spraying sink 7 or its surrounding area are fully mixed, strengthening the washing effect, effectively avoiding the washing blind area, and improving the comprehensiveness and thoroughness of washing.

[0048] The present application also discloses a washing machine, which includes the automatic dosing system with the stirring and mixing function as described in the above embodiment. An automatic dosing function module 4 is further provided on the detergent box assembly 1 for realizing the automatic dosing control of the liquid washing supplies into the water passing channel 6. The automatic dosing function module 4 belongs to the prior art that is already well-known in the automatic dosing system, and the present application will not elaborate on it too much here.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
