Abstract
Description
Technical Field
[0001] This utility model relates to the field of washing machine technology, specifically to a washing machine uniform water inlet device. Background Technology
[0002] Currently, the water intake method of ordinary top-loading washing machines used in households is that the water flows directly into the washing tub in the form of a water jet through the water inlet. However, this results in a small contact area between the clothes and the water, making it impossible for the water to be sprayed evenly on the clothes, resulting in an unsatisfactory washing effect; in addition, there are problems such as insufficient dissolution of detergent and uneven water intake.
[0003] Chinese patent CN204211976U discloses a water inlet device for a washing machine. Located at the top of the washing tub, it includes a circular cover and a base. The base comprises a shell and a rim. The shell is hemispherical and has evenly distributed circular holes. A water inlet is provided on the shell, and a semi-circular protrusion is provided below the inlet. Evenly distributed rectangular openings are provided at the front end of the protrusion. This invention has a simple structure and can disperse and evenly spray water from the inlet onto clothes through the evenly distributed circular holes on the shell, increasing the contact area between the clothes and water and improving the washing effect. However, it lacks detergent mixing and dissolving functions, resulting in insufficient washing synergy, and its water inlet uniformity design has limitations, leading to insufficient stability in water flow distribution. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a structurally optimized uniform water intake device for washing machines.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a washing machine uniform water inlet device, including a box body, a solvent box for holding laundry detergent is provided on the inner side of the box body, a water inlet is provided on the side wall of the solvent box, an annular tube is provided on the inner side wall of the box body, the annular tube is connected to the solvent box, a plurality of water outlet holes are provided on the annular tube, and a plurality of through holes are provided on the bottom surface of the box body.
[0006] Furthermore, the inner depth of the solvent box is greater than the diameter of the annular tube, and both ends of the annular tube are inserted into the upper part of the solvent box and communicate with the solvent box.
[0007] Furthermore, the annular tube is embedded on the inner side of the box, and multiple water outlet holes are equally spaced at the bottom of the annular tube close to the inner side of the box.
[0008] Furthermore, the solvent box is provided with a lid on the top, which is fastened to the top of the solvent box in the form of a hinge or a sliding cover.
[0009] Furthermore, the side of the box is connected to a pivot and a buckle plate opposite to the pivot.
[0010] Furthermore, a reinforcing strip is provided on the bottom surface of the box.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. Through the annular tube and multiple equidistantly distributed water outlets, water flows out evenly and stably along the inner wall of the container, avoiding localized scouring of the container and ensuring thorough mixing of detergent and water, thus improving dissolution efficiency. The embedded installation of the annular tube and the design of the reinforcing strip on the bottom of the container improve the overall structural strength of the device, reduce the risk of deformation after long-term use, and extend its service life. The connection structure and size matching between the solvent box and the annular tube (the depth of the solvent box is greater than the diameter of the annular tube) ensures a stable water flow into the annular tube, preventing liquid overflow and ensuring the continuity and reliability of the water intake process.

Therefore, they should not be construed as limitations on this utility model.
[0019] Combination Figures 1 to 3 The washing machine uniform water intake device shown includes a box body 1. The inner side of the box body 1 is provided with a solvent box 2 for holding laundry detergent. The side wall of the solvent box 2 is provided with a water inlet 3. External water enters the solvent box 2 through the water inlet 3 and mixes with the laundry detergent in the box to form a washing liquid. The inner side wall of the box body 1 is provided with an annular pipe 4, which is connected to the solvent box 2. The annular pipe 4 is provided with multiple water outlet holes 41. The bottom surface of the box body 1 is provided with multiple through holes 5.
[0020] The inner depth of the solvent box 2 is greater than the diameter of the annular tube 4. Both ends of the annular tube 4 are inserted into the upper part of the solvent box 2 and communicate with the solvent box 2, so as to ensure that the solvent box 2 has enough space to hold the detergent and water and prevent liquid from overflowing.
[0021] The annular tube 4 is embedded in the inner side of the box 1. Multiple water outlet holes 41 are opened at equal intervals at the bottom of the annular tube 4 close to the inner side of the box 1. The mixed washing liquid enters the annular tube 4 through the connecting structure. Since the annular tube is embedded in the inner wall of the box 1 and multiple water outlet holes 41 are opened at equal intervals at the bottom, the washing liquid flows out evenly along the inner wall of the box, achieving uniform water intake.
[0022] A lid 21 is provided on the top of the solvent container 2. The lid 21 is fastened to the top of the solvent container 2 by means of a hinge or a sliding cover. The lid 21 is provided to prevent water entering from the water inlet 3 from leaking out from the top of the solvent container 2, while the hinge or sliding cover design makes it easy to open and close, improving the convenience of use.
[0023] The side of the box body 1 is connected to a rotating shaft 6 and a buckle plate 7 opposite to the rotating shaft 6. The rotating shaft 6 facilitates the opening and closing of the box body 1, and the buckle plate 7 ensures a stable installation, improving the assembly flexibility and usage stability of the device. The bottom surface of the box body 1 is provided with a reinforcing strip 8 to enhance the structural strength of the bottom surface of the box body and prevent deformation caused by long-term load.
[0024] Working principle: External water enters the solvent box 2 through the water inlet 3 on the side wall of the solvent box, and mixes with the detergent contained in the box to form a washing liquid. The mixed washing liquid enters the annular pipe 4 from both ends through the connecting structure. Since the annular pipe is embedded in the inner side wall of the box body 1 and has multiple equally spaced water outlet holes 41 at the bottom, the washing liquid flows out evenly along the inner wall of the box body, achieving uniform water intake. The washing liquid flowing out through the annular pipe 4 collects at the bottom of the box body 1 and enters the washing machine through multiple through holes 5 on the bottom surface, completing the water intake process. The lid 21 of the solvent box can be opened to add the washing machine into the solvent box 2, and it can also prevent the water entering through the water inlet 3 from leaking out from the top of the solvent box 2. The rotating shaft 6 and the buckle plate 7 ensure the stable assembly of the box body, and the reinforcing strip 8 enhances the load-bearing capacity of the bottom of the box body, ensuring the stability of the overall structure.
