Description

Technical Field

[0001] The invention belongs to the field of washing machines, and in particular relates to an upper cover assembly of a washing machine and the washing machine. Background Art

[0002] Generally, an existing washing machine includes a housing and a washing drum contained in the housing, wherein a water inlet pipe is connected between the housing and the washing drum so that external water can enter the washing drum through the water inlet pipe. In addition, a tray is also provided on the top of the housing, and a detergent box for putting detergent is provided on the tray. A part of the water entering the washing machine through the water inlet pipe enters the detergent box, and a water outlet connected to the washing drum is also provided on the detergent box. After the washing program of the washing machine is started, external water enters the detergent box through the water inlet pipe and is fully mixed with the detergent in the detergent box. Finally, the mixed washing water flows into the washing drum through the water outlet of the detergent box.

[0003] Specifically, taking a top-loading washing machine as an example, a washing drum is arranged in the housing of the washing machine, a tray seat is arranged on the top of the housing, and the upper cover of the washing machine is pivotally connected to the tray seat so that the washing drum and other components in the housing can be covered by the upper cover. The detergent box of the existing top-loading washing machine is arranged on the tray seat. It is precisely because the installation space of the detergent box and the water inlet component connected to the detergent box needs to be reserved inside the tray seat, so the tray seat usually needs to be arranged at a certain height with the washing drum, so that the overall height size of the washing machine is increased. In this case, on the one hand, when the detergent box is arranged on the tray seat, the user must pull out the detergent box to add detergent, and the operation process is complicated and inconvenient to use; on the other hand, because the detergent box occupies a certain layout space on the tray seat, the structure of the tray seat is greatly restricted, so that the overall height of the tray seat is also increased accordingly.

[0004] Accordingly, a new solution is needed in the art to reduce the overall height of the disc base, so as to achieve an ultra-thin disc base appearance while reducing the cost of the entire device.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0051] In the solution provided by the present invention, since the detergent box 2 is arranged on the upper cover 1, the overall height of the dish seat is reduced, thereby saving the cost of the washing machine.

[0052] On the other hand, the present invention further provides a washing machine, comprising the upper cover assembly of the washing machine described above.

[0053] Embodiment 1

[0054] This embodiment provides an upper cover assembly of a washing machine.

[0055] The upper cover assembly comprises:

[0056] Upper cover 1;

[0057] The detergent box 2 is mounted on the upper cover 1 and connected to the lower surface of the upper cover 1; the bottom wall of the detergent box 2 has an opening 19 in the middle area, and the opening 19 is equipped with a bottom plate 18 that can be opened or closed.

[0058] like Figure 1 As shown, the upper cover assembly of the washing machine provided in this embodiment includes an upper cover 1 and a detergent box 2. The upper cover 1 rotates along the rotating shaft to open or close the washing drum. The detergent box 2 is an overall rectangular parallelepiped structure, and the top wall of the detergent box 2 is connected to the lower surface of the upper cover 1 so that the detergent box 2 is installed on the upper cover 1 as a whole. An opening 19 is provided in the middle area of ​​the bottom wall of the detergent box 2, and the user puts detergent into the detergent box 2 through the opening 19. A movable bottom plate 18 is provided on the bottom wall of the detergent box 2, and the bottom plate 18 rotates to open or close the opening 19. A liquid outlet 11 is provided on the bottom plate 18, and the detergent in the detergent box 2 flows into the washing drum through the liquid outlet 11.

[0059] In the above solution, the detergent box 2 is an integrally formed structure, and only a rectangular opening 19 is provided in the middle area of ​​the bottom wall of the detergent box 2 for putting in detergent. In the solution provided in this embodiment, since the detergent box 2 is arranged on the upper cover 1, the overall height of the dish seat is reduced, and the cost of the washing machine is saved.

[0060] In another solution of this embodiment, the detergent box 2 includes an upper shell 16 and a lower shell 17, and the upper shell 16 and the lower shell 17 enclose a receiving cavity;

[0061] The upper shell 16 is connected to the lower surface of the upper cover 1 , and the opening 19 is provided on the bottom wall of the lower shell 17 .

[0062] Specifically, the upper shell 16 and the lower shell 17 are both open-type groove structures 3;

[0063] The side walls of the open portion of the upper shell 16 / lower shell 17 are inserted into the groove structure of the lower shell 17 / upper shell 16, thereby enclosing the accommodating cavity.

[0064] like Figure 2 As shown, in the above scheme, the detergent box 2 is not an integrally formed structure, but includes an upper shell 16 and a lower shell 17, both of which are openly arranged groove structures 3, and the side wall of the open portion of the upper shell 16 is inserted into the groove of the lower shell 17 and fixedly connected to form a receiving cavity. The upper shell 16 is connected to the lower surface of the upper cover 1, and the opening 19 is arranged on the bottom wall of the lower shell 17.

[0065] In a further solution of this embodiment, the groove structure depth of the upper shell 16 is different from the groove structure depth of the lower shell 17 .

[0066] In this solution, the cross-sectional area of ​​the upper shell 16 is larger than that of the lower shell 17, and the groove depth of the upper shell 16 is smaller than that of the lower shell 17. During assembly, the side wall of the open portion of the lower shell 17 is inserted into the groove of the lower shell 17, and the side wall of the lower shell 17 presses against the top wall of the upper shell 16, and the side walls of the upper shell 16 and the lower shell 17 are fixedly connected to form a receiving cavity.

[0067] In other solutions of this embodiment, the cross-sectional area of ​​the lower shell 17 may be larger than the cross-sectional area of ​​the upper shell 16 , and the groove depth of the lower shell 17 may be smaller than the groove depth of the upper shell 16 .

[0068] In the above scheme, since the detergent box 2 is divided, it is convenient to install the stirring part 8 in the detergent box 2. In the above scheme, the stirring part 8 is installed in the first housing, and the detergent box 2 is also provided with a water inlet so that the washing water enters the containing cavity to dissolve the detergent. The stirring part 8 moves to stir the mixed liquid of the detergent and water so that the mixture is evenly mixed.

[0069] In the above solution, the upper cover 1 includes an upper cover body 101 and a cover body 102, the fixing portion on the detergent box is connected to the upper cover body, and the top wall of the detergent box is fixedly connected to the cover body.

[0070] like Figure 3 and Figure 4As shown, in another solution of this embodiment, the upper cover assembly includes: an upper cover 1 and a detergent box 2. The upper cover 1 includes an upper cover body 101 and a cover body 102, the middle of the upper cover body 101 has a hollow area, and the cover body 102 covers the hollow area. The detergent box 2 includes a shell at least partially located in the hollow area, the shell is connected to the lower surface of the cover body 102, and the shell and the cover body 102 surround a receiving cavity.

[0071] The upper cover assembly provided in this embodiment includes an upper cover body 101, a cover body 102 and a detergent box 2. The upper cover body 101 has a certain thickness and has a hollow area in the middle. The cover body 102 is arranged above the upper cover body 101 and covers the hollow area. The detergent box 2 includes a shell arranged on the lower surface of the cover body 102, the shell and the cover body 102 form a receiving cavity, and the shell is located in the hollow area.

[0072] Specifically, the housing has a groove structure 3 with an open upper side, and the cover 102 covers the upper opening of the groove structure 3 and together with the groove structure 3 forms the accommodating cavity;

[0073] The outer peripheral edge 4 of the groove structure 3 is sealed and connected to the cover body 102 .

[0074] The detergent box 2 includes a housing, the housing has a groove structure 3 with an upper opening, and edges 4 extending outward are arranged around the opening of the housing, and transparent glue is applied to the edge 4. When the cover 102 covers the upper opening of the groove structure 3, the transparent glue seals the housing and the cover 102 together, and a receiving cavity for containing detergent is formed inside the housing.

[0075] In a further solution of this embodiment, a support bar 6 is further provided above the opening of the groove structure 3. The support bar 6 may be provided in multiple pieces, which is not specifically limited in this solution. When installing, the upper surface of the support bar 6 is also coated with transparent glue so that it is adhered to the inner surface of the cover body 102. Thus, the detergent box 2 is fixed more firmly.

[0076] In a further solution of this embodiment, the upper cover assembly further comprises a sealing gasket 7, which is arranged between the groove structure 3 and the cover body 102 to enhance the sealing performance therebetween.

[0077] In a further solution of this embodiment, the detergent box 2 further includes a fixing portion 5;

[0078] One end of the fixing portion 5 is connected to the housing, and the other end is fixedly connected to the upper cover body 101 .

[0079] In the scheme of this embodiment, the detergent box 2 also includes a fixing portion 5 for fixing the detergent box 2 on the upper cover body 101. The specific scheme is that the detergent box 2 includes two integrally formed parts, namely the groove structure 3 surrounded by the shell and the fixing portion 5, and the detergent box 2 as a whole is fixedly connected to the upper cover body 101 through the fixing portion 5. The groove structure 3 surrounded by the shell is used to accommodate detergent. More specifically, the fixing portion 5 is a plate-like structure with a certain thickness, including a first area and a second area, and the thickness of the first area and the second area is different. The first area is connected to the shell, and the second area is connected to the upper cover body 101. Specifically, the thickness of the first area is less than the depth of the groove structure 3, and the side wall at the end of the first area abuts against the inner side wall of the upper cover body 101. The second area is formed by continuing to extend outward at the end of the first area, and the thickness of the second area is less than the thickness of the first area, and the upper surfaces of the first area and the second area are on the same horizontal plane.

[0080] In other solutions of this embodiment, the thickness of the first region may also be equal to the depth of the groove structure 3 .

[0081] In addition, the upper cover body 101 has a recessed area, and the two ends of the recessed area have buckle structures. The extended end of the second area is installed in the recessed area, and the two ends are fixed in the recessed area through the buckle structure.

[0082] In the above solution, since the shell of the detergent box 2 and the cover 102 form a detergent containing cavity, materials are saved and the cost of the washing machine is further saved.

[0083] In a further solution of this embodiment, the area of ​​the cover 102 located above the shell is made of a transparent material.

[0084] In the solution of this embodiment, the cover 102 is made of a whole piece of transparent glass. The open edge 4 of the housing is sealed and connected to the cover 102 to form a receiving cavity, and the user can observe the dissolution of the detergent in the receiving cavity through the glass.

[0085] In another solution of this embodiment, only the area of ​​the cover 102 located above the detergent box 2 is made of transparent glass, and the other areas are made of opaque glass.

[0086] In another solution of this embodiment, when the detergent box 2 is an integral rectangular parallelepiped structure, not only the area of ​​the cover 102 located above the detergent box 2 is made of transparent material, but also the top wall of the detergent box 2 is made of transparent glass. When the detergent box 2 includes a receiving cavity surrounded by an upper shell 16 and a lower shell 17, not only the area of ​​the cover 102 located above the top wall of the upper shell 16 is made of transparent material, but also the top wall of the upper shell 16 of the detergent box 2 is made of transparent glass.

[0087] In the above scheme, since the area of ​​the cover 102 located above the detergent box 2 is made of transparent material, the user can not only clearly see the mixing of water and detergent in the container, the process of detergent generating bubbles, and the waterfall effect caused by the water flow impacting the cover 102 through the cover 102, but also enhance the user experience.

[0088] The solution of this embodiment also includes: providing a first pipeline with a water outlet end located outside the groove structure 3, and a second pipeline communicating with the accommodating cavity;

[0089] The first pipeline and the second pipeline are selectively connected through the water channel conversion component 9.

[0090] In the above scheme, the upper cover assembly is respectively provided with a first pipeline and a second pipeline. The first pipeline is connected to the washing tub of the washing machine, and the second pipeline is connected to the accommodating chamber. A third pipeline and a water circuit conversion component 9 are also provided. The third pipeline is used to connect an external water source. The water circuit conversion component 9 controls the third pipeline to be connected to the first pipeline or the second pipeline. The water circuit conversion component 9 controls the on-off state between the first pipeline, the second pipeline and the third pipeline. When the water circuit conversion component 9 is in the first state, the first pipeline is connected to the third pipeline, and the washing machine is controlled to fill water into the washing tub to immerse the clothes. When the washing tub is filled with water, the water circuit conversion component 9 is controlled to be in the second state, so that the second pipeline is connected to the third pipeline, and the washing machine is controlled to fill water into the detergent accommodating chamber, so that the detergent in the accommodating chamber is fully mixed with water and bubbles are generated.

[0091] Since two pipelines are provided, namely, the water inlet pipelines of the washing tub and the detergent box 2 are separately provided, they complement each other and improve the washing efficiency. In addition, the washing tub is filled with water to soak the clothes and then the bubble detergent is added, so that the clothes are easier to wash.

[0092] The solution of this embodiment also includes: the second pipeline has at least one nozzle 10;

[0093] At least one stirring part 8 is arranged in the groove structure 3;

[0094] The water outlet direction of the nozzle 10 is toward the setting position of the stirring part 8.

[0095] like Figure 4 and Figure 5 As shown, in the solution of this embodiment, the upper cover assembly also includes a stirring part 8, which is arranged in the groove structure 3 of the detergent box 2, and is used to stir the mixed liquid of detergent and water to make it evenly mixed and easier to generate bubbles. In this solution, two stirring parts 8 are provided. It is worth noting that the number of stirring parts 8 can be set according to different situations, and there is no limitation on this.

[0096] The end of the second pipeline is connected to the nozzle 10. In the solution of this embodiment, two nozzles 10 are arranged on the second pipeline. The nozzles 10 are arranged one by one corresponding to the stirring parts 8, and the water outlet direction of the nozzles 10 is toward the setting position of the corresponding stirring parts 8. In other words, the nozzles 10 spray water toward the corresponding stirring parts 8. The stirring parts 8 are driven to rotate by the water flow to realize the bubble generation process of the detergent and water. Of course, there is no limitation on the number of nozzles 10. Preferably, the number of nozzles 10 is greater than or equal to the number of stirring parts 8.

[0097] It is worth noting that when the housing of the detergent box 2 is an integrally formed structure, a through hole is provided on the housing for installing the nozzle 10. When the detergent box 2 is a receiving cavity surrounded by an upper housing 16 and a lower housing 17, a through hole is provided on both the upper housing 16 and the lower housing 17 for installing the nozzle 10.

[0098] The solution of this embodiment also includes: the bottom plate is rotatably mounted on the bottom wall of the detergent box, and the bottom plate 18 is rotated downward to open the opening 19 .

[0099] The bottom plate 18 is provided with a liquid outlet 11;

[0100] The liquid outlet 11 is provided with a liquid outlet valve 15 and an elastic element. When the liquid in the accommodating chamber reaches a preset amount, the liquid outlet valve compresses the elastic element under pressure to open the liquid outlet.

[0101] like Figure 6 As shown, in the above scheme, the bottom plate 18 is movably arranged on the bottom wall of the detergent box 2. When the bottom plate 18 rotates upward, the opening 19 is covered to make the accommodating chamber a closed chamber. When the bottom plate 18 rotates downward, the opening 19 is opened, so that the accommodating chamber is opened. The bottom plate 18 is provided with a liquid outlet 11; the liquid outlet 11 is a through hole formed by a shell, and a liquid outlet valve 15 is installed in the shell. An elastic element is installed below the liquid outlet valve 15. In this scheme, the elastic element is a spring 14, and a sealing sleeve 13 is arranged on the outer periphery of the spring 14. When the total weight of the mixed liquid of detergent and water in the accommodating chamber reaches a set weight, the mixed liquid of detergent and water causes the liquid outlet valve 15 to compress the spring 14, so that it flows out of the accommodating chamber.

[0102] In a further solution of this embodiment, a sealing gasket 7 is provided between the bottom plate 18 and the bottom wall.

[0103] Since the sealing gasket 7 is provided, the sealing between the bottom plate 18 and the bottom wall is strengthened. When the opening 19 is closed, the sealing of the accommodating cavity is better and the detergent will not flow out from the gap between the bottom plate 18 and the bottom wall.

[0104] In a further solution of this embodiment, two liquid outlets 11 are provided on the bottom plate 18, and each liquid outlet 11 is provided at a position below the stirring part 8. This solution increases the number of liquid outlets 11, thereby improving the efficiency of mixing liquid and preventing the phenomenon that the liquid outlet 11 is blocked and cannot mix liquid.

[0105] In a further solution of this embodiment, a cover opening handle 12 for opening the bottom plate 18 is further provided on the bottom plate 18. More specifically, the cover opening handle 12 is provided at a position between the two liquid outlets 11.

[0106] In a further solution of this embodiment, a guide portion 20 is provided in the accommodating cavity;

[0107] The air guide portion 20 is disposed in the lower housing 17 and is located on a side opposite to the rotation axis of the bottom plate 18 .

[0108] Specifically, the guide portion has a folded state and an unfolded state;

[0109] When the opening 19 is in a closed state, the guide portion is in a folded state and is completely retracted into the accommodating cavity;

[0110] When the opening 19 is in the open state, the guide portion 20 switches to the unfolded state and extends out from the accommodating cavity to carry the laundry treating agent and introduce it into the accommodating cavity.

[0111] More specifically, one end of the guide portion 20 extends into the accommodating cavity through the opening 19, and both sides of the end portion are fixedly connected to the lower shell 17, and there is a gap between the middle area and the edge of the opening 19 of the lower shell 17;

[0112] The guide portion 20 has a guide channel 21 , and the guide channel 21 is a concave structure arranged in the middle area of ​​the guide portion 20 along the extending direction of the guide portion 20 .

[0113] In the above scheme, the upper cover assembly also includes a guide portion 20, and the detergent is added to the accommodating cavity through the guide portion 20. The guide portion 20 is a sheet structure made of a flexible material, which is elastic and foldable. The guide portion 20 is arranged inside the accommodating cavity and has two states. When the bottom plate 18 is rotated upward to close the opening 19, the guide portion 20 outside the accommodating cavity is folded and compressed and placed inside the accommodating cavity. When the bottom plate 18 is rotated downward to open the opening 19, the guide portion 20 overcomes its own elastic force and pops out of the accommodating cavity to carry the clothing treatment agent and introduce it into the accommodating cavity.

[0114] The specific location of the guide part 20 is at the edge of the opening 19 on the side opposite to the rotation axis of the bottom plate 18. Since the guide part 20 is a sheet structure, it has two ends, one end is inserted into the receiving cavity through the opening 19, and the two sides of the end are fixedly connected to the edge of the opening 19, and there is a gap between the middle area and the edge of the opening 19. When the user pours detergent onto the guide part 20, the detergent enters the receiving cavity through the gap.

[0115] The guide portion 20 provided in this embodiment has a guide channel 21, which is a recessed structure provided in the middle area of ​​the guide portion 20, and is provided along the ejection direction of the guide portion 20. Since the guide channel 21 is provided on the guide portion 20, there is a gap between the middle area of ​​the guide portion 20 and the edge of the opening 19.

[0116] In a further solution of this embodiment, the guide portion 20 has two ends, namely a first end and a second end. When the bottom plate 18 opens the opening 19, the first end of the guide portion 20 extends into the accommodating cavity, and the second end pops out of the accommodating cavity. The guide portion 20 has a downward inclination angle along the liquid adding direction, that is, the horizontal height of the second end is greater than the horizontal height of the first end. This solution makes it easier for the detergent on the guide portion 20 to flow into the accommodating cavity.

[0117] In the above scheme, since the guide channel 21 is provided on the guide part 20, the guide part 20 pops out from the accommodating chamber when the user opens the opening 19. The user pours detergent onto the guide part 20, and the detergent enters the accommodating chamber along the guide channel 21 on the guide part 20. Since the lower edge 4 of the opening 19 on the shell is at a distance from the side wall of the shell, it is ensured that the detergent entering the accommodating chamber will not leak out of the accommodating chamber.

[0118] The solution provided in this embodiment reduces the overall height of the dish seat and saves the cost of the washing machine because the detergent box 2 is arranged on the upper cover 1. In addition, since the stirring part 8 is installed in the accommodating cavity, the detergent and water are mixed more thoroughly, thereby improving the washing effect. In general, the above solution improves the user experience.

[0121] The washing machine provided in this embodiment utilizes the upper cover assembly, and the detergent box 2 is not installed on the dish seat, but on the upper cover 1, thereby reducing the height of the dish seat and saving the manufacturing cost of the washing machine.

[0122] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
