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

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an upper cover assembly of a washing machine and a washing machine. The solution reduces the overall height of the disc seat by integrating the detergent box with the upper cover of the washing machine, thereby saving the cost of the washing machine.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] In one aspect, an upper cover assembly of a washing machine comprises:

[0011] The detergent box comprises a shell at least partially located in the hollow area, the shell is connected to the lower surface of the cover, and the shell and the cover form a accommodating cavity.

[0012] The solution provided by the present invention reduces the overall height of the dish seat and saves the cost of the washing machine because the detergent box is arranged on the cover body. In addition, because the shell of the detergent box and the cover body form a detergent containing cavity, materials are saved, further saving the cost of the washing machine.

[0013] Furthermore, the area of ​​the cover located above the shell is made of a transparent material.

[0014] Furthermore, the housing has a groove structure with an open upper side, and the cover body covers the upper opening of the groove structure and together with the groove structure forms the accommodating cavity;

[0015] The outer peripheral edge of the groove structure is sealed and connected to the cover body.

[0016] Furthermore, the upper cover body is provided with a first pipeline whose water outlet is located outside the groove structure, and a second pipeline communicating with the accommodating cavity;

[0017] The first pipeline and the second pipeline are selectively connected through the water channel conversion component.

[0018] Further, the second pipeline has at least one nozzle;

[0019] At least one stirring component is arranged in the groove structure;

[0020] Wherein, the water outlet direction of the nozzle is toward the setting position of the stirring component.

[0021] Further, the detergent box also includes a fixing portion;

[0022] One end of the fixing portion is connected to the shell, and the other end is fixedly connected to the upper cover body.

[0023] Furthermore, an opening is provided in the middle area of ​​the bottom wall of the groove structure;

[0025] Furthermore, a liquid outlet is provided on the bottom plate;

[0026] A liquid outlet valve and an elastic element are installed in the liquid outlet. 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.

[0027] Furthermore, a guide portion is provided in the accommodating cavity;

[0028] When the opening on the bottom wall is in an open state, the guide portion pops out from the accommodating cavity to carry the laundry treating agent and guide it into the accommodating cavity.

[0029] On the other hand, the present invention further provides a washing machine, comprising the upper cover assembly of the washing machine described above.

[0030] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0031] 1. The solution provided by the present invention reduces the overall height of the dish seat and saves the cost of the washing machine because the detergent box is arranged on the cover body. Also, because the shell of the detergent box and the cover body form a detergent containing cavity, materials are saved, further saving the cost of the washing machine.

[0032] 2. In the solution provided by the present invention, since the area of ​​the cover located above the shell is made of transparent material, the user can not only clearly see the mixing of water and detergent in the accommodating cavity and the process of detergent generating bubbles through the cover, but also see the waterfall effect produced by the water flow impacting the cover, thereby enhancing the user experience.

[0033] 3. In the solution provided by the present invention, since at least one stirring component is arranged in the groove, the detergent and water are fully mixed, thereby greatly improving the foaming efficiency of the detergent.

[0054] The solution provided by the present invention 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 cover 102. In addition, since the shell of the detergent box 2 and the cover 102 form a detergent receiving cavity, materials are saved, further saving the cost of the washing machine.

[0055] On the other hand, the present invention further provides a washing machine, comprising the upper cover assembly of the washing machine described above.

[0056] The washing machine of the present invention uses the upper cover assembly of the washing machine, so that the overall height of the dish seat is reduced, thereby reducing the cost of the entire machine.

[0057] Embodiment 1

[0058] This embodiment provides an upper cover assembly of a washing machine.

[0059] The upper cover assembly comprises: an upper cover 1 and a detergent box.

[0060] The upper cover 1 includes an upper cover body 101 and a cover body 102. The upper cover body 101 has a hollow area in the middle, 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 form a receiving cavity.

[0061] like Figure 1-2As shown, 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.

[0062] That is, the detergent box 2 has a shell, which encloses an open groove structure 3, and the cover body 102 serves as a top cover to cover the opening of the groove structure 3, thereby forming a receiving cavity for containing detergent.

[0063] In the above solution, since the detergent box 2 is arranged on the cover 102, the overall height of the tray is reduced, saving the cost of the washing machine. In addition, since the shell of the detergent box 2 and the cover 102 form a detergent receiving cavity, materials are saved, further saving the cost of the washing machine.

[0064] 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;

[0065] The outer peripheral edge 4 of the groove structure 3 is sealed and connected to the cover body 102 .

[0066] like Figure 2 As shown, the detergent box 2 includes a housing, the housing has a groove structure 3 with an upper opening, and the housing is provided with an outwardly extending edge 4 around the opening, 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.

[0067] 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.

[0068] 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.

[0069] In a further solution of this embodiment, the detergent box 2 further includes a fixing portion 5;

[0070] 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 .

[0071] like Figure 3 As shown, 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 of 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.

[0072] In other solutions of this embodiment, the thickness of the first region may also be equal to the depth of the groove structure 3 .

[0073] 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.

[0074] In a further solution of this embodiment, the area of ​​the cover 102 located above the shell is made of a transparent material.

[0075] In another solution of this embodiment, only the area of ​​the cover 102 located above the shell is made of transparent material, and the other areas are made of opaque glass.

[0076] In the above solution, since the area of ​​the cover 102 located above the shell is made of transparent material, the user can not only clearly see the mixing of water and detergent in the container and the process of detergent generating bubbles through the cover 102, but also see the waterfall effect produced by the water flow impacting the cover 102, thereby enhancing the user experience.

[0077] 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;

[0078] The first pipeline and the second pipeline are selectively connected through the water channel conversion component 9.

[0079] 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.

[0080] 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.

[0081] The solution of this embodiment also includes: the second pipeline has at least one nozzle 10;

[0082] At least one stirring part 8 is arranged in the groove structure 3;

[0083] The water outlet direction of the nozzle 10 is toward the setting position of the stirring part 8.

[0084] like Figure 3 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.

[0085] 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.

[0086] The solution of this embodiment also includes: an opening 19 is provided in the middle area of ​​the bottom wall of the groove structure 3;

[0087] A movable bottom plate 18 is also provided on the bottom wall of the groove structure 3 for opening or closing the opening 19 .

[0088] The bottom plate 18 is provided with a liquid outlet 11;

[0089] 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.

[0090] 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.

[0091] In a further solution of this embodiment, a sealing gasket 7 is provided between the bottom plate 18 and the bottom wall.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] The solution of this embodiment also includes: a guide portion 20 is provided in the accommodating cavity;

[0096] When the opening 19 on the bottom wall is in an open state, the guide portion 20 pops out from the accommodating cavity to carry the laundry treating agent and guide it into the accommodating cavity.

[0097] Specifically, the end of the guide portion 20 extends into the accommodating cavity through the opening 19, and the two sides of the end 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;

[0098] The guide portion 20 has a guide channel 21 , which is a concave structure arranged in the middle area of ​​the guide portion 20 along the ejection direction of the guide portion 20 .

[0099] like Figure 1 As shown, in the above scheme, the upper cover assembly also includes a guide portion 20, and the detergent is added to the accommodating chamber 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 chamber and has two states. When the bottom plate 18 is rotated upward to close the opening 19, the guide portion 20 outside the accommodating chamber is folded and compressed and placed inside the accommodating chamber. 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 chamber to carry the clothing treatment agent and introduce it into the accommodating chamber.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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 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.

[0104] In the above solution, since the detergent box 2 is arranged on the cover 102, the overall height of the dish seat is reduced, saving the cost of the washing machine. In addition, since the shell of the detergent box 2 and the cover 102 form a detergent receiving cavity, materials are saved, further saving the cost of the washing machine. In general, the above solution improves the user experience.

[0105] Embodiment 2

[0106] This embodiment is a top cover assembly of a washing machine further described on the basis of the first embodiment.

[0107] The upper cover assembly provided in this embodiment includes: an upper cover 1;

[0108] The detergent box 2 is mounted on the upper cover 1 and connected to the lower surface of the upper cover 1; the middle area of ​​the bottom wall of the detergent box 2 has an opening 19, and the opening 19 can be opened or closed by a bottom plate 18 mounted on the bottom wall.

[0109] like Figure 4 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.

[0110] 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.

[0111] 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.

[0112] 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;

[0113] 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 .

[0114] Specifically, the upper shell 16 and the lower shell 17 are both open-type groove structures 3;

[0115] The side wall of the open portion of the upper shell 16 or the lower shell 17 is inserted into the groove of the lower shell 17 or the upper shell 16 to be fixedly connected to form a receiving cavity.

[0116] 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.

[0117] In a further solution of this embodiment, the groove depths of the upper shell 16 and the lower shell 17 are different.

[0118] 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.
