DETAILED DESCRIPTION

[0025] The utility model is further described below in combination with the drawings.

[0026] The directions involved in the specification are all based on the directions of the washing machine box premixing structure when the washing machine box premixing structure normally works, and are not limited to the directions when the washing machine box premixing structure is stored and transported, and only represent relative positional relationships, and do not represent absolute positional relationships.

[0027] Example 1:

[0028] like Figure 1 and Figure 2 As shown, a premixing structure for a washing machine box includes a detergent box 1 fixed to the washing machine and a drawer 2 installed in the detergent box 1 and used to hold detergent. The detergent box 1 is provided with a water inlet 13 and a water outlet 14. The water inlet 13 can be connected to an external water source to supply water to the detergent box 1, and the water outlet 14 can be connected to the interior of the washing machine to pass water dissolved with detergent into the washing machine. The water inlet 13 is provided with a water inlet pipe 131 extending above the front end of the drawer 2. The water inlet pipe 131 extends into the front end of the drawer 2, thereby ensuring that the water inlet position of the water inlet pipe 131 is close to the front end of the drawer 2, thereby ensuring that the water inlet covers the space inside the drawer 2 to the greatest extent possible, and avoiding the problem that the water inlet position is too far back and some detergent cannot be flushed away. A leakage gap is provided between the rear end of the drawer 2 and the detergent box 1, and the leakage gap is connected to the water outlet 14; a rear panel 22 is provided at the rear end of the drawer 2, and mesh holes are evenly provided on the rear panel 22; the mesh holes connect the interior of the drawer 2 with the leakage gap.

[0029] In this embodiment, the drawer 2 is mounted on the detergent box 1 in a pull-out manner. The front of the detergent box 1 is provided with an opening 11 for inserting or removing the drawer 2. The drawer 2 comprises a base plate for holding the detergent, side panels on either side of the base plate, a rear panel 22 at the rear end of the base plate, and a front panel 21 at the front end of the base plate that closes the opening 11. A handle 211 is provided on the outside of the front panel 21 to facilitate inserting and removing the drawer 2. Positioning bosses 12 are symmetrically positioned on either side of the opening 11, extending from the opening 11 toward the rear end of the detergent box 1. The drawer 2 is inserted into the opening 11 and supported by the positioning bosses 12. Furthermore, the positioning bosses 12 extend downwardly from the front end of the detergent box 1 toward the rear end. This arrangement creates a certain installation angle when the drawer 2 is installed. This angle causes the drawer 2 to tilt downward from front to back, thus preventing liquid from accumulating inside the drawer 2.

[0030] Furthermore, in order to increase the coverage area of ​​the water outlet of the water inlet pipe 131 in the left-right direction, the water outlet of the water inlet pipe 131 is a flat structure stretched left-right.

[0031] As an improvement to this embodiment, normally, when people pour detergent into the drawer 2, the detergent will accumulate in the middle position of the drawer 2. In order to maximize the impact of the water flow and enable the water flow to contact the detergent to the greatest extent, the water inlet 13 is set at the back of the detergent box 1, and the water outlet position of the water inlet pipe 131 is located in the middle position above the drawer 2.

[0032] Pull the drawer 2 out of the opening 11, then add detergent into the drawer 2; after adding the detergent, insert the drawer 2 back into the detergent box 1; pour tap water into the water inlet 13, the tap water will impact the detergent on the bottom plate, forming a certain mixing effect; the water flow will impact the detergent onto the mesh of the back panel 22, and the mesh will block the flow, thus reducing the flow rate of the detergent, and the water flow will flow between the meshes, achieving sufficient mixing; the mixed liquid will flow down from the liquid leakage gap 31 after passing through the mesh, and then be discharged into the washing machine from the water outlet 14.

[0033] As shown in Figure 4 As a further improvement of the back panel 22 in this embodiment, the overflow port 221 is symmetrically arranged on the upper left and right sides of the back panel 22. When the water flow mixes with the washing liquid, it will generate a certain amount of foam, which is not easy to pass through the mesh. By symmetrically arranging the overflow port 221 on the upper left and right sides of the back panel 22, the overflow port 221 will guide the water flow carrying the foam to flow quickly downward from the left and right sides of the back panel 22.

[0034] The bottom of the back panel 22 is provided with a clear liquid port 222 between the bottom plate of the drawer 2. The clear liquid port 222 can discharge the accumulated liquid at the bottom of the drawer 2 after the washing machine is filled with water. In this embodiment, the clear liquid port 222 is preferably arranged at the bottom of the middle position of the back panel 22, because the speed of the water flow during flow is greater than that of the detergent, and the water pressure is greater at the middle position, so the water flow will impact the detergent to the left and right sides, and the detergent will concentrate on the left and right sides of the drawer 2. The clear liquid port 222 is arranged at the bottom of the middle position of the back panel 22 to avoid the detergent flowing out of the drawer 2 directly from the clear liquid port 222.

[0035] The stepped mesh plate structure 4 is fixed on the detergent box 1 at the bottom of the drawer 2, and the stepped mesh plate structure 4 includes the middle mesh plate 41 and the side mesh plates 42 symmetrically arranged on both sides of the middle mesh plate 41. The height of the side mesh plate 42 is higher than that of the middle mesh plate 41 and is inclined from the left / right side wall of the detergent box 1 to the middle mesh plate 41; the middle mesh plate 41 guides the liquid falling from above to flow onto the middle mesh plate 41.

[0036] As shown in Figure 3 The washing liquid will disperse to both sides under the impact of the water flow, and the washing liquid will accumulate on both sides of the front panel 21. Some of the washing liquid will flow down from the mesh without being mixed, fall onto the side mesh plate 42, and then be blocked by the mesh of the side mesh plate 42, so that it adheres to the side mesh plate 42. Then, under the impact of the water flow, it can flow to the middle along the side mesh plate 42. During the flow process, it is diluted by the water flow falling from above and flows to the middle mesh plate 41 under the action of gravity until it is fully diluted. At the same time, by arranging the stepped mesh plate structure 4, multiple water flows are caused to fall, thereby improving the mixing effect of the water flow and the detergent.

[0037] Several diverter plates 51 are evenly spaced at the outlet 14, dividing it into multiple flow channels. This division reduces the velocity of unmixed detergent, allowing it to collide with the water flow again and mix. Furthermore, this division reduces the space available at the outlet 14, increasing the probability of contact between the water flow and the detergent, and improving the mixing effect.

[0038] Example 2:

[0039] This embodiment improves the rear panel 22 based on the first embodiment. Figure 5 As shown, the rear panel 22 is an arc-shaped panel with its center extending toward the rear end of the drawer 2 and its left and right sides curved toward the front end of the drawer 2. The arrangement of the arc-shaped panel increases the contact area between the rear panel 22 and the detergent. When the detergent adheres to the rear panel 22, it is more dispersed, facilitating mixing with the water flow and allowing the detergent to be fully dissolved. At the same time, the left and right sides of the rear panel 22 are more tightly gathered, shortening the distance to the water outlet and increasing the impact of the water flow.

[0040] Example 3:

[0041] This embodiment is further improved on the basis of the second embodiment. Figure 6 As shown, in order to enhance the mixing effect of detergent and water, the rear panel 22 is further improved, and a guide plate 223 is provided on the top of the rear panel 22, which is bent toward the inside of the drawer 2. The guide plate 223 can guide the water flow toward the inside of the drawer 2, so that the water flow forms a rolling state inside the drawer 2. This state is conducive to the stirring of the water flow with the detergent, so that the two are evenly mixed. At the same time, this stirring can accelerate the dissolution rate of the detergent and also make the detergent produce more delicate and rich foam.

[0042] The utility model provides a premixing structure for a washing machine box to solve the technical problem in the prior art that direct addition of detergent to the washing machine causes insufficient dissolution of part of the detergent and results in low detergent utilization rate. The utility model improves the utilization rate of the detergent, thereby improving the cleaning ability and rinsing effect of the fully automatic pulsator washing machine.

[0043] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
