[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0031] Reference Figure 1 As shown, the utility model discloses a premixing channel structure, comprising: a mixing cover plate 1 having a mixing channel 2, water and detergent are passed into the mixing channel 2, and the purpose of setting the mixing channel 2 is to make water and detergent miscible, so as to achieve a better cleaning effect;

[0032] As mentioned above: There are three solutions in the prior art for improving the mixing efficiency of water and detergent, but these three methods have all modified the structure of the existing mixing channel 2, which not only increases the occupied space of the mixing channel 2, but also increases the cost due to its complex structure, and are not applicable in actual use;

[0033] In order to solve this problem, that is, to increase the mixing efficiency of water and detergent without changing the existing mixing channel 2, in the present embodiment, a boost injection member 3 is provided in the mixing channel 2, and the boost injection member 3 has a boost hole 31 for the flow of the fluid in the mixing channel 2, and the aperture of the boost hole 31 gradually decreases along the flow direction of the fluid, that is, the inlet of the boost hole 31 is large and the outlet is small. In actual use, water and detergent enter from the inlet of the boost hole 31. As the diameter of the boost hole 31 gradually decreases, the water and detergent are continuously pressurized during the flow process, which is conducive to the mutual dissolution of water and detergent under the action of pressure. Finally, the water and detergent flow out from the outlet of the boost hole 31, the pressure drops suddenly, and the liquid is guided to shrink and diffuse rapidly, which can form a spray dispersion effect, increase the contact area between water and detergent, and finally achieve the goal of improving the mixing effect of detergent and water.

[0034] Specifically, in the present embodiment, when setting the inlet and outlet sizes of the boosting hole 31, on the one hand, it is necessary to consider the flow rate problem, that is, the inlet and outlet aperture ratio of the boosting hole 31 cannot be set too small, which will affect the flow of the fluid and easily cause the accumulation of water and detergent, which is easy to overflow during injection. On the other hand, the inlet and outlet aperture ratio of the boosting hole 31 cannot be set too large, which will not have the effect of boosting. Therefore, after many experimental comparisons, the diameter of the mixing channel 2 is set to 22mm, and the inlet diameter of the boosting hole 31 is set to 15mm~20mm. It is determined that when the inlet and outlet aperture ratio of the boosting hole 31 is 0.5~0.7, it can not only meet the boosting demand and achieve the purpose of fully mixing the detergent and water, but also ensure the normal flow of the detergent and water in the mixing channel 2.

[0035] Reference Figure 2 and Figure 3As shown, in actual use, the boost injection member 3 can be in the form of a single hole or multiple holes. Regardless of whether the boost injection member 3 is a single hole or a multiple hole structure, the boost hole 31 is set to be inclined relative to the flow direction of the fluid. The single hole boost hole 31 can be inclined downward or upward. A plurality of the boost holes 31 are distributed in the mixing channel 2 along the horizontal direction, and the outlets of the plurality of boost holes 31 are alternately arranged in the vertical direction in the mixing channel 2. The purpose of setting the boost hole 31 to be inclined is to prevent water and detergent from accumulating in the boost hole 31. It can be imagined that if the boost hole 31 is set as a horizontal hole, there will be an accumulation platform. When the water and detergent are stopped from being introduced, there may be some residue on the platform.

[0036] Reference Figure 1 and Figure 4 As shown, in actual use, a plurality of boost injection members 3 are arranged in the mixing flow channel 2, and the boost holes 31 in each of the boost injection members 3 are arranged obliquely relative to the flow direction of the fluid, and the inclination directions of the boost holes 31 in two adjacent boost injection members 3 are opposite, so that water and detergent can swing left and right when passing through the boost holes 31 of the two boost injection members 3, and the outlets of the boost holes 31 in the two adjacent boost injection members 3 are alternately arranged in the vertical direction, so that water and detergent can swing up and down when passing through the boost holes 31 of the two boost injection members 3, therefore, water and detergent can be turned up and down and left and right in the mixing flow channel 2 under the guidance of the boost holes 31, forming a rotating vortex effect, which can further improve the mixing efficiency of water and detergent.

[0037] Specifically, Figure 1 and Figure 4 As shown, in the present embodiment, the mixing flow channel 2 may have a plurality of bending sections, which can form a plurality of straight flow channels through bending, and a boost injection component 3 is provided in each straight flow channel. According to actual use requirements, two boost injection components 3 can be provided in each straight flow channel to cooperate with each other, so that water and detergent can be turned up and down and left and right in the straight flow channel under the guidance of the two boost holes 31, forming a rotating vortex effect, which can further improve the mixing efficiency of water and detergent.

[0038] Specifically, Figure 2 and Figure 3 As shown, in order to fix the boost injection component 3 in the mixing flow channel 2, the boost injection component 3 also includes a fixing pin 32. A fixing hole for inserting the fixing pin 32 is opened on the side wall of the mixing flow channel 2. The position of the boost injection component 3 can be fixed by the pin-hole cooperation, which can prevent the boost injection component 3 from being washed away by the mixed fluid of water and detergent.

[0039] Reference Figure 5 As shown, in order to facilitate the assembly of the boost injection component 3 in the mixing cover plate 1, the mixing cover plate 1 includes: a first cover plate 11 and a second cover plate 12, the first cover plate 11 and the second cover plate 12 are buckled together to form a sealed mixing channel 2, the first cover plate 11 and the second cover plate 12 are detachably assembled for use, and in actual use, a fixing hole can be opened on the second cover plate 12, the boost injection component 3 is first placed on the second cover plate 12, and then the first cover plate 11 is buckled on the second cover plate 12, so that the boost injection component 3 can be set in the mixing channel 2.

[0040] In this embodiment, in order to pass water and detergent into the mixing channel 2, a first liquid inlet 13 and a second liquid inlet 14 are provided at one end of the mixing channel 2, the first liquid inlet 13 is provided on the first cover plate 11, the first liquid inlet 13 is a water inlet, the second liquid inlet 14 is provided on the second cover plate 12, the second liquid inlet 14 is a detergent inlet, and a drain port 15 is provided at the other end of the mixing channel 2.

[0041] Reference Figure 6 As shown, in order to further accelerate the mixing speed of water and detergent in the mixing channel 2, a spiral structure 4 is further provided in the mixing channel 2. In this embodiment, the spiral structure 4 is provided as a spiral rod, and positive and negative alternating threads are provided on the spiral rod. The positive and negative alternating threads can guide the liquid to rotate 360° forward and backward. In the process of the liquid passing through, the distribution state of water and detergent can be disrupted, so that the water and detergent can be mixed quickly.

[0042] The utility model also provides a drum washing machine, including the above-mentioned premixing flow channel structure. Obviously, the purpose of the premixing flow channel structure of the utility model is to mix two different fluids to improve the mixing efficiency of different fluids. In actual use, the two fluids can be water and detergent, which are applied to cleaning fields such as washing machines and dishwashers. The two fluids can also be set as chemical solvents and applied to the preparation of mixed reagents in the chemical field. Therefore, the premixing flow channel structure of the utility model can be applied in different fields.

[0043] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
