Detailed implementation manners

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0057] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0058] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mount", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] As Figures 1 to 9 shown, the present invention provides an embedded washing machine and its box body.

[0060] As Figure 1 and Figure 2 shown, the embedded washing machine includes a box body 1. The inner wall of the box body 1 encloses a cavity with a front opening. A bucket assembly 2 is arranged in the cavity, and the bucket assembly 2 is slidably arranged in the cavity of the box body 1 through the front opening.

[0061] The barrel assembly 2 comprises an outer barrel, a rotatable inner barrel is arranged in the outer barrel, and a rotatable impeller is arranged in the inner barrel.

[0062] When the user uses the built-in washing machine, the barrel assembly 2 is pulled out from the housing 1, clothes are put into the inner barrel through the clothes loading port 21 of the barrel assembly 2, and then the barrel assembly 2 is pushed back into the cavity of the housing 1. After setting the washing program, the built-in washing machine runs according to the washing program.

[0063] like Figure 3 and Figure 4 As shown, the box 1 for the built-in washing machine provided by the present invention comprises a shell 11 provided with a front opening, the shell 11 constitutes the side wall of the box 1, and an upper cover 12 is installed above the shell 11. The upper cover 12 has a hollow chamber 130, and a plurality of spray ports 124 are provided on the bottom wall 123 of the hollow chamber 130; the upper cover 12 is provided with a water inlet pipe 134 communicating with the hollow chamber 130, and the water inlet pipe 134 is connected to the water inlet valve of the built-in washing machine.

[0064] When the barrel assembly 2 is located inside the housing 1 , the spray port 124 corresponds to the clothing loading port 21 .

[0065] After water inlet begins, the water inlet valve opens, and water flows into the hollow chamber 130 of the upper cover 12 through the water inlet pipe 134, and then sprays into the inner barrel through the spray port 124, so that the clothes can be fully immersed in water, and the clothes can be soaked in advance, which can improve the washing ability of the washing machine. Moreover, when rinsing and filling water, the water is sprayed evenly, which can fully remove the detergent in the clothes, improve the washing ratio, and enhance the user experience.

[0066] The above is the core idea of ​​the present invention. In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0067] In some embodiments of the present invention, Figures 5 to 9 As shown, the bottom wall 123 of the hollow chamber 130 is in a structure that is higher inside and lower outside, and the water inlet pipe 134 is connected to the side wall of the hollow chamber 130 .

[0068] In detail, when the washing program is running, the impeller and / or the inner drum rotates, so that the water flow in the inner drum rolls up and down, driving the clothes to turn over. When the built-in washing machine runs the rinsing program, most of the water in the outer drum is first discharged through the drain pipe, and then when the dehydration program is started, the inner drum is rotated at high speed to throw out the remaining water and detergent on the clothes under the action of centrifugal force, and then water is introduced into the inner drum to rinse the remaining detergent in the clothes.

[0069] Therefore, after the dehydration program ends, the clothes in the inner tub are closely attached to the tub wall of the inner tub due to the action of centrifugal force. At this time, when the rinsing program is running, the water inlet valve of the built-in washing machine opens. Since the bottom wall 123 of the hollow chamber 130 of the upper cover 12 has a structure with a higher inner side and a lower outer side, and the water inlet pipe 134 is connected to the side wall of the hollow chamber 130, therefore, the water flow first enters the inner tub through the spray holes 124 on the outer side of the bottom wall 123 of the hollow chamber 130, sprays the clothes closely attached to the tub wall in the inner tub, the water is sprayed evenly, and can fully remove the detergent in the clothes, improving the rinsing effect.

[0070] The above solution of the present invention abandons the problem that the flat water supply method has been adopted in the prior art, resulting in a single water supply method and being unable to meet the water supply requirements under multiple programs.

[0071] In addition, for the flat water supply method in the prior art, when the water inlet flow rate is small, it is easy to cause uneven water distribution in the washing tub, and it is easy to cause the situation of no water in some areas, reducing the spraying effect.

[0072] However, in the above solution of the present invention, the central area is higher and the outermost area is the lowest, which can automatically adjust the spraying area range according to the water pressure, and the spraying is relatively uniform.

[0073] In some embodiments of the present invention, the bottom wall 123 of the hollow chamber 130 is formed with several regions from the center to the outer edge, and the several regions have a stepped structure with a higher inner side and a lower outer side.

[0074] Specifically, when the water inlet flow rate is small, using the flow characteristics of water, only the lowest part on the outermost side is sprayed. When the water inlet flow rate increases, the water flow further overflows to the area of the previous step, and spraying is performed from the higher part, realizing the automatic coordination of the spraying water volume and its spraying area.

[0075] In a further solution, several of the spray holes 124 in each region are evenly distributed in a radial pattern from the center to the outer edge.

[0076] The shape of the spray holes 124 can be: circular, triangular, regular polygon or a combination form, etc. The arrangement of the spray holes 124 on the bottom wall 123 of the hollow chamber 130 is evenly distributed in a radial pattern from the center to the outer edge. The above solution makes the spraying effect of the water flow more uniform and can improve the visual experience of customers.

[0077] For the hollow chamber 130 of the upper cover 12, there are various ways of forming it.

[0078] In some embodiments of the present invention, such as Figures 6 to 9As shown, the upper cover 12 includes a body 129 and a spraying body. The body 129 is connected above the housing 11. The spraying body is installed on one side of the body 129 facing the housing 11. The spraying body includes a first housing 121 and a second housing 122 which are snap-connected. The first housing 121 and the second housing 122 enclose to form the hollow chamber 130. The bottom wall 123 of the second housing 122 constitutes the bottom wall 123 of the hollow chamber 130. The water inlet pipe 134 is arranged on the side wall of the first housing 121.

[0079] The above solution enables the first housing 121 and the second housing 122 to be manufactured separately and then assembled. The manufacturing process is simple and easy to implement.

[0080] In a further solution, as Figure 6 shown, a plurality of buckles 128 are arranged on the edges of the first housing 121 and the second housing 122. The first housing 121 and the second housing 122 are fixed together through the cooperation relationship of the buckles 128. Further, a sealing ring 125 is arranged at the snap-connection joint of the first housing 121 and the second housing 122 to improve the sealing performance.

[0081] In a further solution, a plurality of crossed annular reinforcing ribs 126 and radial reinforcing ribs 127 are arranged on the inner side of the first housing 121.

[0082] Since a certain water pressure needs to be borne in the first housing 121, crossed annular reinforcing ribs 126 and radial reinforcing ribs 127 are arranged on the inner side of the first housing 121 to improve the strength of the first housing 121, avoid deformation of the first housing 121 caused by too much water pressure, affect the connection relationship between the first housing 121 and the second housing 122, and cause water leakage.

[0083] Preferably, a plurality of pressings are formed on the body 129 to increase the strength of the body 129.

[0084] In a further solution, a plurality of radially extending mounting plates 131 are arranged on the spraying body along the circumferential direction. The mounting plates 131 are fixedly connected to the body 129.

[0085] Specifically, four mounting plates 131 are arranged on the spraying body along the circumferential direction. Reinforcing ribs are arranged on the mounting plates 131. Screw holes 132 are arranged at the ends of the mounting plates 131. Correspondingly, screw posts 133 are arranged at the corresponding positions of the body 129. The spraying body is fixed on the body 129 through screws.

[0086] In a further solution, at least part of the water inlet pipe 134 is arranged on the mounting plate 131 on the opposite side of the front opening to fix the water inlet pipe 134, avoid the movement of the water inlet pipe 134, and the structure is regular.

[0087] In addition, the water inlet pipe 134 is arranged on the mounting plate 131 on the opposite side of the front opening, which is closer to the main water inlet structure of the built-in washing machine, avoiding the situation that the water inlet pipe 134 is too long and occupies more space.

[0088] The spray body can also be a separate structure. During the integral molding process, a hollow chamber 130 is formed inside the spray body itself. A water inlet pipe 134 is arranged on the side wall of the spray body of the built-in washing machine. The structure is optional and the production cost is low.

[0089] The upper cover 12 or the spray body of the present invention can be replaced as a separate component.

[0090] In some embodiments of the present invention, the upper cover 12 includes a main body 129 and a spray plate. The main body 129 is connected above the housing 11; the spray plate covers one side of the main body 129 facing the housing 11, and together with the main body 129 encloses to form the hollow chamber 130, and the spray plate constitutes the bottom wall 123 of the hollow chamber 130.

[0091] Preferably, a plurality of pressings are formed on the main body 129 to increase the strength of the main body 129.

[0092] Specifically, the spray plate and the main body 129 are fixed by structures such as screws.

[0093] In some embodiments of the present invention, the axis of the water inlet pipe 134 matches the circumferential direction of the hollow chamber 130 so that the water flow entering the hollow chamber 130 via the water inlet pipe 134 first enters the outside of the hollow chamber 130. It can be understood that the water inlet pipe 134 should be connected to the water inlet valve of the built-in washing machine, and the on-off of the water inlet pipe 134 is controlled by the water inlet valve.

[0094] Specifically, the axial direction of the water inlet pipe 134 is substantially tangent to the edge of the hollow chamber 130, so that the water flow entering the hollow chamber 130 via the water inlet pipe 134 enters tangentially, and is in a spiral flow state from the outer edge to the center in the hollow chamber 130, making the water inlet more uniform and avoiding the situation of only local spraying.

[0095] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above into equivalent embodiments of equivalent changes. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
