[0001] The utility model relates to the technical field of washing machines, in particular to a detergent premixing device for washing machines and a washing machine. Background Art

[0002] As people's living standards continue to improve, laundry equipment has become more and more popular, and washing machines have gradually become an indispensable part of people's lives. The dissolution of detergents is a research focus in the washing machine industry. Promoting the full dissolution of detergents can not only save the amount of detergent, but also solve the problem of clothing damage and improve the cleanliness of clothing. At present, the way most washing machines dissolve detergents is as follows: the water from the main water inlet valve flows through the bottom cover, and flows into the drum together with the detergent put into the bottom cover by the suction and discharge pump. The inner drum rotates to promote the dissolution of detergent in the water. This method of dissolving detergents is simple and reliable but time-consuming. In addition, most washing machines currently use several continuous curved flow channels to premix detergents, and then spray them into the drum. The premixing flow channel is long and complex.

[0003] Therefore, it is necessary to provide a new method to solve the above technical problems. Utility Model Content

[0028] The technical solution of the utility model will be clearly and completely described below through specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See attached Figures 1 to 7As shown, a detergent premixing device for a washing machine of the present application comprises a material box 1 installed on the washing machine, the material box 1 is filled with detergent, a top cover 2 and a bottom cover 3 are installed on the material box 1, a premixing flow channel 4 is provided above the material box 1, the top cover 2 and the premixing flow channel 4 are hot-melt sealed, the material box 1 and the bottom cover 3 are fixed by snaps, a suction and discharge pump 5 is installed on the side of the bottom cover 3, a water inlet 6, a detergent inlet 7 and a water outlet 14 are provided on the premixing flow channel 4, a water inlet valve feeds water into the premixing flow channel 4 from the water inlet 6, the suction and discharge pump 5 draws detergent from the material box 1 and pumps it into the premixing flow channel 4, and water and detergent are mixed in the premixing flow channel 4. A plurality of pairs of spoilers 8 are installed in the premixing channel 4, each spoiler 8 is a rectangular plate, and edge ridges 9 are provided at both ends and the middle of each spoiler 8. A premixing channel slot 10 is provided on the premixing channel 4, and the edge ridges 9 on each spoiler 8 can be clamped in the premixing channel slot 10 of the premixing channel 4. Each edge ridge 9 corresponds to the premixing channel slot 10 one by one. The premixing channel slot 10 makes the shape of the two spoilers 8 in each pair of spoilers 8 upside down, and the flow state of the mixed liquid of water and detergent becomes a double-layer alternating water flow after passing through each pair of spoilers 8, thereby promoting the mixed solution to flip and merge in the premixing channel 4, and accelerating the dissolution of the detergent. By setting the premixing channel 4, the detergent and water first enter the premixing channel 4 to mix in advance and then enter the washing machine drum, eliminating the process of rotating and dissolving in the inner drum, reducing the total washing time, and the detergent is mixed more evenly, thereby improving the washing effect.

[0030] For better, see the attached Figure 3 As shown, in this embodiment, a plurality of resistance-increasing ribs 11 are installed in the premixing channel 4, and the ends of each resistance-increasing rib 11 are installed on the inner wall of the premixing channel 4 at an inclined angle. The direction of each resistance-increasing rib 11 is opposite to the water flow direction in the premixing channel 4, thereby adjusting the resistance of the premixing channel 4. Different washing machines have different requirements for the water flow rate of the water outlet 14 of the premixing channel 4. By changing the number of resistance-increasing ribs 11 in the premixing channel 4, the channel resistance can be changed, thereby obtaining the required outlet flow rate.

[0031] For better, see the attached Figure 7 As shown, in a conventional washing machine, detergent is put into the bottom cover, and water is introduced to clean the bottom cover wall after the detergent is put in. However, the bottom cover has a large space, and the water flow cannot completely cover the detergent residue, and the water flow rate is slow, so the cleaning effect is limited. In this embodiment, it can be seen from the detergent flow path 13 that the suction and discharge pump 5 extracts detergent from the material box 1 and pumps it into the premixing channel 4 for mixing. After the detergent is put in, water is introduced into the water inlet 6, and the detergent residue in the narrow premixing channel 4 is cleaned without dead angles. The water flow rate is fast and the cleaning effect is good.

[0032] Preferably, attend the Figure 2 As shown, the upper cover of the material box 1 of the present application is provided with a material box cover 12, and the material box cover 12 is fixed to the material box 1 by a buckle.

[0033] Preferably, the water outlet 14 of the premixing channel 4 in this embodiment is connected to a spray head through a water pipe, and the mixed solution of water and detergent fully mixed is directly sprayed onto the clothes through the spray head, which can improve the washing efficiency and reduce the washing time.

[0034] After the material box 1 of the present application is inserted into the bottom cover 3, the suction and discharge pump 5 extracts detergent from the material box 1 and pumps it to the premixing channel 4 at the top of the material box 1 to merge with water. The flow state of the mixed liquid is changed by the spoiler 8 to promote the dissolution of the detergent in the water, and finally flows out from the water outlet 14 in front of the premixing channel 4 into the barrel.

[0035] The above description of the disclosed embodiments enables professionals in the field to implement or use the utility model. Various modifications to these embodiments will be apparent to professionals in the field, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the principles and novel features disclosed herein.
