DETAILED DESCRIPTION

[0026] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0027] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0029] In order to save the internal space of the existing mini washing machine, the detergent box is usually arranged under the drum. At the same time, in order to take into account the automatic detergent dispensing function, an internal circulation pipeline with a water pump is added to pump out the water in the drum, and after filtering through the filter, it is transported to the mixer to mix with the detergent, and then the mixed detergent is transported back to the drum to achieve the purpose of automatic detergent dispensing. Therefore, the automatic detergent dispensing mechanism of the existing washing machine has defects: a mixer for mixing water and detergent needs to be independently set up, and the number of parts used is large, and the cost is high.

[0030] In order to overcome the above technical problems, Figure 1 As shown, this embodiment provides an automatic detergent dispensing structure, including a circulating water circuit and a detergent liquid supply circuit; the circulating water circuit includes a water pump and a filter box 3 connected in series, the water pump is used to pump out the water in the washing drum, and then return it to the washing drum after filtering by the filter box 3; the detergent liquid supply circuit includes a detergent box 1 and a detergent pump 2 connected in series, the output end of the detergent pump 2 is connected to the filter box 3, and the detergent pump 2 is used to pump the detergent in the detergent box 1 into the filter box 3 to mix with water.

[0031] Specifically, when the automatic detergent delivery structure of this embodiment is working, the detergent pump 2 pumps the detergent in the detergent box 1 into the filter box 3, and the circulating water circuit pumps the water in the washing drum into the filter box 3 to mix with the detergent. After the detergent is dissolved, it is circulated back into the washing drum to achieve the purpose of automatic detergent delivery. Among them, in addition to filtering the water pumped out of the washing drum to avoid the problem of impurities in the water causing the water pump to be blocked, the filter box 3 can also serve as a container for mixing detergent and water, so there is no need to add a mixer for mixing detergent and water separately. Compared with the prior art, the specially set mixer is omitted, the structure is simplified, the number of structural parts is reduced, and the cost is reduced.

[0032] In one embodiment, the filter box 3 includes a water inlet interface 311, a water return interface 312 and a liquid inlet interface 313, the water inlet interface 311 is connected to the washing drum through a water inlet pipe 6, the water return interface 312 is connected to the washing drum through a water return pipe 7, and the detergent pump 2 is connected to the liquid inlet interface 313 through a liquid inlet pipe 5.

[0033] By integrating the water inlet interface 311, the water return interface 312 and the liquid inlet interface 313 in the filter box 3, the filter box 3 is used not only as a filtering device for water flow but also as a container for mixing detergent and water, thereby achieving maximum utilization of functions.

[0034] In one embodiment, the water pump is disposed between the water return interface 312 and the washing tub.

[0035] The water pump is arranged between the return water interface 312 and the washing drum, which can directly push the filtered and mixed water out of the filter box 3 and quickly return to the washing drum through the return water pipe 7. Such a layout ensures the smoothness and efficiency of the circulating water circuit, and helps to quickly complete the automatic delivery process of the detergent. In addition, arranging the water pump on the return water path also helps to prevent the water pump from being affected by unfiltered impurities, thereby extending the service life of the water pump. Because all water will be filtered by the filter box before reaching the water pump, impurities that may clog or damage the water pump are effectively removed. In general, this layout not only optimizes the path of water circulation and improves the efficiency of automatic delivery, but also protects the key component water pump, ensuring the stability and reliability of the entire system.

[0036] In one embodiment, the water inlet pipe 6 is connected to the bottom of the washing tub, and the water return pipe 7 is connected to the top of the washing tub.

[0037] Connecting the water inlet pipe 6 to the bottom of the washing drum can ensure that the water pump can extract the water in the washing drum, especially the dirty water or water containing more impurities deposited at the bottom. In this way, the water in the washing drum will be cleaner after being filtered by the filter box, reducing the impact of impurities on the washing drum and clothes. Secondly, connecting the return pipe 7 to the top of the washing drum is conducive to achieving uniform distribution of detergent and water in the washing drum. At the same time, since the liquid will naturally form convection in the washing drum, the mixed liquid injected from the top will be better mixed with the clothes and water in the drum, improving the dissolution and distribution effect of the detergent, thereby enhancing the washing effect.

[0038] In addition, this layout also helps to reduce eddy currents and dead corners in the washing drum, allowing detergent and water to more fully contact every corner of the clothes, improving the uniformity and thoroughness of washing.

[0039] In one embodiment, the filter box 3 further includes a drainage interface 314 , and the drainage interface 314 is connected to the drainage pipe 8 .

[0040] After the laundry is finished, the laundry wastewater can be filtered through the filter box 3 and then discharged through the drain pipe 8. Since the filter box 3 has preliminarily filtered the wastewater, the impurities and stains in the discharged wastewater will be relatively low, which reduces the burden on the drainage system and reduces the pollution to the environment.

[0041] In one embodiment, the filter box 3 includes a box shell 31 and a filter 32 detachably installed in the box shell 31 . The water entering the water inlet interface 311 is filtered by the filter 32 and then discharged through the return water interface 312 or the drainage interface 314 .

[0042] During long-term use, the filter will gradually accumulate impurities and stains, affecting the filtering effect. In this solution, the user can easily clean or replace the detachable filter 32 through the detachable design, which makes this process simple and fast, improving the user's experience. In addition, this design also makes the replacement of the filter 32 more economical and efficient. When the filter 32 is damaged or needs to be replaced, the user only needs to buy a new filter 32 without replacing the entire filter box 3, thereby reducing maintenance costs.

[0043] For specific settings, refer to Figure 3-4 , a mounting port is provided on one side of the box shell 31, and a water inlet interface 311, a water return interface 312, a liquid inlet interface 313 and a drainage interface 314 are provided on the other side walls; the filter 32 has a filter net bag, which can be loaded into the box shell 31 from the mounting port, and after loading, the sealing plate connected to one side of the filter 32 can just seal and block the mounting port, and to ensure the sealing performance, a waterproof ring is provided between the sealing plate and the mounting port. Preferably, the opening of the net bag faces upward, and the water inlet interface 311 is provided on the top wall of the box shell 31; at the same time, the water return interface 312 and the drainage interface 314 are both provided on the side of the box shell 31 opposite to the mounting port, ensuring that the water entering from the water inlet interface 311 can be discharged after being filtered.

[0044] In one embodiment, referring to Figure 3-5 The filter box 3 is provided with a diffuser 9 connected to the liquid inlet interface 313, the diffuser 9 has a buffer cavity, and the diffuser 9 is provided with a plurality of fine holes 921 connecting the buffer cavity and the inner cavity of the filter box 3.

[0045] In a traditional automatic detergent dispensing mechanism, the detergent pipeline and the water pipeline are connected through a mixer. After the detergent dispensing stops, the continuously flowing water will rush into the connection between the mixer and the detergent pipeline, and the detergent in the connecting part of the mixer and the detergent pipeline will continue to be flushed out and brought into the washing drum, resulting in the problem of excessive detergent input and waste.

[0046] In this embodiment, a diffuser 9 connected to the liquid inlet interface 313 is arranged in the filter box 3, and fine holes 921 are densely arranged on the diffuser 9. After the detergent pump 2 squeezes the detergent from the liquid inlet interface 313 into the buffer cavity of the diffuser 9, the detergent in the diffuser 9 will be dispersed and squeezed out from the fine holes 921 into the filter box 3 under the pressure of the detergent pump 2, and the function of adding detergent to the filter box 3 can also be realized. The advantage of the arrangement of the diffuser 9 is that the aperture of the fine holes 921 arranged on the diffuser 9 is greatly reduced relative to the liquid inlet interface 313, and the water flowing in the filter box 3 is difficult to rush into the fine holes 921 to continue to flush out the detergent in the diffuser 9, and then, under the premise of realizing the normal delivery function, it is effectively avoided that the water that continues to flow rushes into the detergent pipeline to continue to flush out the detergent after the drive of the detergent pump 2 is turned off, thereby effectively reducing the problem of excessive waste of detergent input. In addition, the detergent is dispersed and squeezed into the filter box 3 through the densely distributed fine holes 921. This design makes the detergent delivery more uniform and delicate, allowing the detergent to dissolve more uniformly and quickly into the water, thereby improving the washing effect.

[0047] Preferably, the diameter of the micropores 921 is 0.5 to 1 mm.

[0048] In one embodiment, referring to Figure 5 The diffuser 9 includes a connecting head 91 and an enlarged ball head 92 . The connecting head 91 is connected to the liquid inlet interface 313 , and the fine hole 921 is arranged on the enlarged ball head 92 .

[0049] The diffuser 9 is provided with an enlarged ball head 92, so as to increase the surface area of ​​the diffuser 9, facilitate the provision of more fine holes 921 on the diffuser 9, provide a sufficiently large total extrusion area for the detergent, and ensure that the detergent has sufficient extrusion efficiency.

[0050] In one embodiment, an intermediate compartment 4 is provided between the detergent box 1 and the detergent pump 2 , and the intermediate compartment 4 is provided with a liquid level sensor 41 .

[0051] An intermediate compartment 4 is provided between the detergent box 1 and the detergent pump 2. The detergent in the detergent box 1 can be transported to the intermediate compartment 4 for buffering. A liquid level sensor 41 is also provided. The liquid level sensor 41 needs to be connected to the control system of the washing machine. When the liquid level sensor 41 detects that the liquid level in the intermediate compartment 4 is low, the control system reminds the user that the detergent stock is insufficient and that the detergent needs to be refilled into the detergent box 1.

[0052] On the other hand, a washing machine is provided, comprising the above-mentioned automatic detergent dispensing structure.

[0053] Based on the automatic detergent dispensing structure of this embodiment, the washing machine of this embodiment also has the advantages of simple structure, small number of parts and components, and low cost.
