Description

Technical Field

[0001] The present invention relates to the technical field of built-in equipment for washing machines, and in particular to a shower device for washing machines. Background Art

[0002] After the water inlet valve of the washing machine is opened, water flows directly into the washing tub through the opening of the detergent input box. The detergent cannot be fully dissolved and flows onto the clothes to be washed, which will make the clothes not cleaned cleanly. The shower head is a device used to control the speed and direction of the water flow into the washing machine. Therefore, the structure of the shower head needs to be designed according to whether the water is used to wash clothes or to dissolve detergent.

[0003] At present, if the shower assembly used in the washing machine meets the requirement of three or more water outlets, three-way water inlet is usually adopted, which will result in high cost. When two-way water inlet is used, a large amount of splashing water will be generated when the water columns meet, which will cause water to flow between the chambers. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems in the related art to a certain extent. To this end, one purpose of the present invention is to provide a shower device for a washing machine. Once the water in each water outlet cavity of the present invention enters from the water inlet, it cannot form backwater after being blocked by each water retaining rib, ensuring that each water outlet cavity will not interfere with each other when water enters. When the water columns of the first water inlet and the second water inlet meet, water splashes upward, and the water retaining protrusion forms a barrier at the intersection of the two water columns. Because the raised surface and the surrounding surface form a step, water cannot spread to the second water outlet cavity and the third water outlet cavity, protecting other chambers. The present invention can effectively solve the problem of splashing water when the water columns meet and the water flow in each chamber, and solve the problem of only being able to use a single shower head for water inlet, while improving the efficiency of water inlet and reducing costs.

[0005] A shower device for a washing machine according to an embodiment of the present invention comprises a shower assembly and a powder box, wherein the powder box is slidably mounted in an inner cavity of the shower assembly;

[0006] The shower assembly comprises an upper cover, a shower shell and a water inlet box, wherein the upper cover is snap-connected with the shower shell to form an inner cavity between the upper cover and the shower shell, and the shower shell is snap-connected with the water inlet box to form a water inlet cavity between the shower shell and the water inlet box;

[0007] The side of the shower shell away from the powder box is provided with a first water inlet and a second water inlet, the inner cavity of the shower shell is divided into a first water outlet cavity, a second water outlet cavity and a third water outlet cavity by a baffle, the bottoms of the first water outlet cavity, the second water outlet cavity and the third water outlet cavity are all provided with shower holes, and the side of the shower shell located at the second water outlet cavity is provided with a water outlet.

[0008] Preferably, the first water inlet and the second water inlet are installed in a V-shape on the side of the shower housing, and the water outlet ends of the first water inlet and the second water inlet are arranged in the inner cavity of the shower housing.

[0009] Preferably, the first water outlet chamber is arranged between the second water outlet chamber and the third water outlet chamber, and the water inlet ends of the first water outlet chamber, the second water outlet chamber and the third water outlet chamber are provided with partition ribs for diversion.

[0010] Preferably, a first chamber, a second chamber and a third chamber are defined in the powder box.

[0011] Preferably, a first chamber is installed below the first water outlet chamber and has the same shape as the first water outlet chamber, a second chamber is installed below the second water outlet chamber and has the same shape as the second water outlet chamber, and a third chamber is installed below the third water outlet chamber and has the same shape as the third water outlet chamber.

[0012] Preferably, a mounting block is provided on the outer side of the upper portion of the powder box, and a mounting groove corresponding to the mounting block is provided on the inner side of the upper portion of the water inlet box.

[0013] Preferably, siphon openings are provided in both the first chamber and the second chamber, and siphon opening covers are installed on the siphon openings.

[0014] Preferably, a first water retaining rib for controlling water flow is installed in the first water outlet cavity, a second water retaining rib for controlling water flow is installed in the second water outlet cavity, and a third water retaining rib for controlling water flow is installed in the third water outlet cavity.

[0015] Preferably, a water retaining protrusion is provided on the top of the upper cover.

[0016] Preferably, the water inlet end of the third water outlet cavity is arranged in parallel with the second water inlet, and the water inlet end of the second water outlet cavity is arranged in parallel with the first water inlet.

[0017] The beneficial effects of the present invention are:

[0018] The upper cover is connected with the shower shell by snapping. When water enters the first water inlet, water enters the second water outlet cavity, and the shower hole in the second water outlet cavity and the water outlet discharge water at the same time. The shower hole in the second water outlet cavity rinses the second cavity, and the water discharged from the water outlet rinses the glass bowl. When water enters the second water inlet, water enters the third water outlet cavity, and the shower hole in the third water outlet cavity discharges water to rinse the third cavity. When water enters the first water inlet and the second water inlet at the same time, the two water columns intersect to form one water column, and water enters the first water outlet cavity, and the shower hole in the first water outlet cavity rinses the first cavity.

[0019] Once water from each water outlet chamber of the present invention enters from the water inlet, backwater cannot be formed after being blocked by each water retaining rib, thereby ensuring that each water outlet chamber will not interfere with each other when water is entering. When the water columns of the first water inlet and the second water inlet meet, water splashes upward, and the water retaining protrusion forms a barrier at the intersection of the two water columns. Because the protruding surface and the surrounding surface form a step, water cannot diffuse to the second water outlet chamber and the third water outlet chamber, thereby protecting other chambers. The present invention can effectively solve the problems of water splashing when the water columns meet and water cross-talk in each chamber, and solves the problem of water inlet only by a single shower head, while improving the efficiency of water inlet. The present invention realizes that two water inlet pipes can have four-way water outlet, and uses water flow counter-flow to save at least one water inlet control, reduce at least one water inlet valve, and reduce costs.

The shower hole 211 in the second water outlet chamber 24 rinses the second chamber 33, and the water out of the water outlet 23 rinses the glass bowl. When water enters the second water inlet 21, the water enters the third water outlet chamber 25, and the shower hole 211 in the third water outlet chamber 25 discharges water to rinse the third chamber 34. 2 When water enters the first water inlet 22 and the second water inlet 21 at the same time, the two water columns intersect to form a water column, and the water enters the first water outlet chamber 26. The shower hole 211 in the first water outlet chamber 26 flushes the first chamber 32. Once the water in each water outlet chamber of the present invention enters from the water inlet, it cannot form backwater after being blocked by each water retaining rib, thereby ensuring that each water outlet chamber will not interfere with each other during water inlet. When the water columns of the first water inlet 22 and the second water inlet 21 intersect, water splashes upwards. The water retaining protrusion 6 forms a barrier at the intersection of the two water columns. Because the protruding surface and the surrounding surface form a step, water cannot diffuse to the second water outlet chamber 24 and the third water outlet chamber 25, thereby protecting other chambers. The present invention can effectively solve the problems of water splashing when the water columns intersect and water flow in each chamber, and solves the problem of only being able to use a single shower head for water inlet, while improving the efficiency of water inlet and reducing costs.
