Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to a washing machine with an outer drum cover and the same. Background Art

[0002] As consumers' quality of life improves, washing machines have become indispensable to people's lives. At present, washing machines include an outer shell, an outer barrel and an inner barrel are arranged inside the outer shell, and a control panel seat is arranged above the inner barrel and the outer barrel. Among them, a delivery chamber and various control components are arranged on the control panel seat, and the delivery chamber is connected with the delivery device, so that the delivery device can inject the detergent, laundry liquid, disinfectant, softener and other additives to be delivered into the delivery chamber, and then the water flow of the washing machine flows through the delivery chamber and flushes the above additives to the liquid outlet of the delivery chamber. The liquid outlet of the delivery chamber on the control panel seat is connected with the inner and outer barrels through the delivery port on the outer barrel cover, so that the additives flowing out with the water will pass through the outer barrel cover and directly flow between the inner and outer barrels, and then enter the inner barrel through the water holes opened on the inner barrel, so as to realize the washing, soaking and other treatments of the clothes contained in the inner barrel.

[0003] However, the prior art generally has the following defects:

[0004] During the operation of the washing machine, a small amount of incompletely diluted detergent, washing powder, etc. often remains on the side walls of the inner and outer drums, especially at the inlet of the outer drum cover. This will cause the inner drum to rotate at high speed during the dehydration stage, generating a rotating wind blowing in the circumferential direction between the inner and outer drums.

[0005] Under the action of rotating wind, detergent, washing powder and other additives between the inner and outer barrel walls or water droplets mixed with the above additives will flow upward to the bottom of the outer barrel cover and flow along the bottom of the outer barrel cover toward the barrel axis, causing the residual detergent, washing powder and the like to flow into the inner barrel and adhere to the clothes again, affecting the washing effect of the clothes;

[0006] At the same time, some of the detergent, washing powder and other additives between the inner and outer barrel walls or water droplets mixed with the above additives will flow back upward from the delivery port on the outer barrel cover under the action of the rotating wind and flow back into the delivery cavity again, which will not only cause the problem of residual additives in the delivery cavity, but also affect the delivery accuracy of subsequent programs of the washing machine;

[0007] In addition, a part of the detergent, washing powder and other additives between the walls of the inner and outer drums or water droplets mixed with the above additives will flow upward from the opening in the middle of the control panel seat under the action of the rotating wind to the machine cover set on the control panel seat of the washing machine, the inner wall of the clothing inlet of the control panel seat, and even overflow to the floor of the user's home, etc.

[0008] Therefore, the existing washing machine using the above-mentioned outer drum cover will not only cause the clothes in the drum to be not washed clean, but also affect the appearance of the washing machine, pollute the internal parts of the washing machine and even produce abnormal noise, which is easy to be complained by users and affect the user experience.

[0009] In view of this, the present invention is proposed. Summary of the invention

[0010] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an outer drum cover and a washing machine to prevent residual additives between the inner and outer drums from overflowing to the surroundings due to the rotating wind when the washing machine is dehydrating, thereby achieving the purpose of improving the cleaning degree of the washing machine and preventing the appearance of the washing machine from being contaminated.

[0011] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0012] The utility model relates to an outer barrel cover. The outer barrel cover is provided with retaining ribs protruding downwards. The extending direction of the retaining ribs is staggered with the radial direction of the outer barrel cover.

[0013] Furthermore, the outer barrel cover is a horizontally arranged annular structure, and a delivery opening is provided on the annular outer barrel cover which passes through from top to bottom, and a plurality of retaining ribs protruding downward are provided at the delivery opening.

[0014] Furthermore, the annular outer barrel cover is provided with an opening extending through from top to bottom, and a water retaining member corresponding to the covering opening is detachably installed on the outer barrel cover. The water retaining member is provided with a delivery port extending through from top to bottom, and a plurality of spaced and downwardly protruding retaining ribs are provided at the delivery port of the water retaining member.

[0015] Furthermore, the retaining ribs are arranged at intervals along the radial direction of the annular outer barrel cover.

[0016] Furthermore, the extension direction of each retaining rib is parallel to the same tangential direction of the annular outer barrel cover;

[0017] Alternatively, each retaining rib extends along the circumferential direction of different concentric circles, and each concentric circle is concentrically arranged with the outer barrel cover.

[0018] Furthermore, each retaining rib protrudes downward from the lower side of the outer barrel cover;

[0019] Preferably, the upper half of each retaining rib is a vertical portion extending vertically up and down, and the lower half is an inclined portion that gradually inclines from top to bottom away from the center of the outer barrel cover.

[0020] Furthermore, the outer barrel cover is provided with a plurality of openings, each opening is provided with a detachable water retaining member, each water retaining member is provided with a delivery port, and the delivery port is provided with a plurality of retaining ribs protruding and extending downward;

[0021] Preferably, a water retaining member is provided on the left and right sides of the annular outer barrel cover respectively, and the two water retaining members are symmetrically arranged.

[0022] To achieve the above-mentioned purpose, the present invention also introduces a washing machine, which includes an outer barrel, an inner barrel installed in the outer barrel, and an outer barrel cover as described above is installed at the barrel mouth of the outer barrel. The outer barrel cover at least covers the gap between the outer barrel and the inner barrel, and the downwardly protruding ribs arranged on the outer barrel cover extend into the gap between the outer barrel and the inner barrel.

[0023] Furthermore, the outer barrel cover is annular, the outer periphery of the annular outer barrel cover is sealed with the inner wall of the outer barrel mouth, the radial dimension of the inner periphery of the outer barrel cover is smaller than the radial dimension of the inner barrel mouth, and each retaining rib is spaced apart from the inner barrel wall and the outer barrel wall;

[0024] Preferably, the outer barrel cover is located above the barrel opening of the inner barrel, and a distance is maintained between the outer barrel cover and the barrel opening of the inner barrel.

[0025] Furthermore, a control disk seat is provided on the top of the outer shell of the washing machine, the barrel axes of the outer barrel and the inner barrel are coaxial and extend vertically, and the barrel mouth is opened upward, a delivery cavity is provided on the control disk seat, and a liquid outlet is provided at the bottom of the delivery cavity, which is opposite to the delivery port opened on the outer barrel cover.

[0026] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0027] 1. Through the above arrangement, the retaining ribs can block the radial airflow on the lower side of the outer barrel cover, guide the airflow on the lower side of the outer barrel cover to flow downward, and prevent it from directly flowing into the inner barrel from the gap between the outer barrel cover and the inner barrel mouth, thereby preventing the residual detergent, washing powder and other additives between the inner and outer barrels from being affected by the rotating wind generated by the high-speed rotation of the inner barrel and flowing into the inner barrel, the control disc seat, etc., thereby achieving a significant technical progress in improving the washing efficiency of the washing machine and reducing the pollution to the appearance of the washing machine.

[0028] 2. By setting the retaining ribs to be vertical at the top and inclined at the bottom, the retaining ribs can effectively prevent the residual detergents, washing powder and other additives between the barrels from flowing back upward and flowing back into the delivery cavity from the delivery port, thereby effectively reducing the residual additives after the washing machine is working, improving the control accuracy of the washing machine, and reducing the failure rate of the washing machine; at the same time, the above structure also guides the incoming water flow, thereby increasing the water pressure at the delivery port and ensuring the smoothness of the water inlet.

[0029] 3. By setting retaining ribs in the gap between the inner barrel mouth and the outer barrel cover, the airflow between the barrels is effectively blocked from flowing back from the top gap into the barrel, thereby effectively preventing the residual additives between the barrels from diffusing and overflowing to the exterior surface of the washing machine, thereby improving the cleanliness of the washing machine and significantly improving the user experience.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] like Figures 1 to 5 As shown, a washing machine is introduced in an embodiment of the present invention, which includes: an outer shell 100; an outer barrel 200 is arranged in the outer shell 100, the outer barrel 200 is installed in the outer shell 100 via a shock-absorbing member, the axis of the outer barrel 200 extends vertically, and a barrel mouth is arranged on the top; a coaxially arranged inner barrel 300 is arranged in the outer barrel 200, and the inner barrel 300 is also arranged as a barrel-shaped structure with an open top and a closed bottom, and a coaxially arranged inner barrel shaft is connected to the bottom of the inner barrel 300, the upper end of the inner barrel shaft is connected to the bottom of the inner barrel, and the lower end passes through the outer barrel and is connected to a motor installed below the bottom of the outer barrel, so that the inner barrel 300 can be driven by the motor to rotate and installed in the outer barrel 200. At the same time, in order to improve the washing effect, other washing components, such as a impeller, a stirring column, etc., can be installed in the inner barrel 300. The impeller, stirring column and other washing components can be connected to the motor directly or through a reduction clutch device after passing through the inner barrel 300 and the outer barrel 200 through the corresponding shaft, so as to realize synchronous or asynchronous rotation of the inner barrel 300 and the impeller, stirring column and other washing components, so as to wash and dehydrate the load in the inner barrel 300.

[0044] like Figures 1 to 5 As shown, in the embodiment of the present invention, an outer barrel cover 500 is provided at the barrel mouth of the outer barrel 200, and the outer barrel cover 500 at least covers the top open parts of the barrel mouths of the inner and outer barrels; preferably, the outer barrel cover 500 is a horizontally arranged annular structure, the outer periphery of the annular outer barrel cover 500 is connected to the inner wall of the barrel mouth of the outer barrel, the inner periphery of the annular outer barrel cover 500 is above the barrel mouth of the inner barrel, and the radial dimension of the inner periphery of the annular outer barrel cover 500 is greater than the radial dimension of the barrel mouth of the inner barrel, so that the annular outer barrel cover 500 blocks the top of the gap between the inner and outer barrels, and makes the gap between the inner and outer barrels communicate with the interior of the inner barrel 300 through the gap between the outer barrel cover 500 and the barrel mouth of the inner barrel.

[0045] like Figures 1 to 5 As shown, in the embodiment of the present invention, the outer barrel cover 500 is provided with a downwardly protruding retaining rib 1, the extending direction of the retaining rib 1 is staggered with the radial direction of the outer barrel cover 500, and the lower end of the retaining rib 1 is lower than the height of the inner barrel mouth, so that the retaining rib 1 at least partially extends into the gap between the inner and outer barrels. Therefore, the retaining rib 1 can block the radial airflow flowing from the lower side of the outer barrel cover 500, guide the airflow from the lower side of the outer barrel cover 500 to flow downward, and prevent it from directly flowing into the inner barrel 300 from the gap between the outer barrel cover 500 and the inner barrel mouth, thereby preventing the residual detergent, washing powder and other additives from being affected by the rotating wind generated by the high-speed rotation of the inner barrel 300 and flowing into the inner barrel 300, the control disc seat 400 and other places when the inner and outer barrels are placed, thereby achieving the purpose of improving the washing efficiency of the washing machine and reducing the pollution to the appearance of the washing machine.

[0046] Embodiment 1

[0047] like Figures 1 to 3 As shown, in this embodiment, an outer barrel cover is introduced, and a downwardly protruding retaining rib 1 is provided on the outer barrel cover 500, and the extending direction of the retaining rib 1 is staggered with the radial direction of the outer barrel cover 500. By providing the downwardly protruding retaining rib 1 on the outer barrel cover 500, the airflow between the inner and outer barrels can be blocked by the retaining rib 1 and will not flow radially along the lower side of the outer barrel cover, thereby preventing the generation of rotating wind under the outer barrel cover 500, thereby achieving effective shielding of the gap between the inner barrel mouth and the outer barrel cover 500, and effectively preventing the residual additives between the inner and outer barrels from flowing into the inner barrel 300, the control plate seat 400, etc.

[0048] In this embodiment, an annular outer barrel cover 500 is provided with an opening extending through from top to bottom, and a water retaining member 600 corresponding to the covering opening is detachably installed on the outer barrel cover 500. The water retaining member 600 is provided with a delivery port 2 extending through from top to bottom, and the delivery port 2 of the water retaining member 600 is provided with a plurality of spaced-apart, downwardly protruding retaining ribs 1.

[0049] In this embodiment, the retaining ribs 1 are located at the lower side of the loading port 2. The retaining ribs 1 arranged at intervals divide the loading port 2 into a plurality of relatively independent parts, so that the loading port 2 forms a grid-like structure. While effectively preventing the generation of rotating wind between the inner and outer barrels, it can also achieve water flow and allow the water flow of the washing machine to pass smoothly.

[0050] like Figures 1 to 3As shown, in this embodiment, the delivery port 2 extends a certain distance in the radial direction of the annular outer barrel cover 500, and a plurality of retaining ribs 1 are arranged at intervals at the delivery port 2, and each retaining rib 1 is arranged at intervals along the radial direction of the annular outer barrel cover 500, so that each retaining rib 1 can effectively block the airflow flowing in the radial direction under the outer barrel cover 500 and guide it to flow downward, thereby effectively preventing the residual added materials between the inner and outer barrels from flowing into the inner barrel 300 through the gap between the inner periphery of the outer barrel cover 500 and the barrel mouth of the inner barrel.

[0051] In this embodiment, the extension direction of each blocking rib 1 is parallel to the same tangential direction of the annular outer barrel cover 500, so that the blocking rib 1 is perpendicular to the radial direction of the outer barrel cover 500, thereby maximizing the wind blocking area of ​​the blocking rib 1 and effectively improving the blocking effect of the blocking rib 1 on the rotating wind (not indicated in the drawings);

[0052] Or, if Figures 1 to 3 and Figure 5 As shown, in this embodiment, each retaining rib 1 extends along the circumferential direction of different concentric circles, and each concentric circle is concentrically arranged with the outer barrel cover 500, so that the retaining rib 1 is bent and extended, which can further increase the extension distance of the retaining rib 1 to enhance the blocking effect of the retaining rib 1 on the rotating wind.

[0053] In this embodiment, each retaining rib 1 protrudes downward from the lower side of the outer barrel cover 500, so that the lower end of the retaining rib 1 is set lower than the lower side of the outer barrel cover 500. The retaining rib 1 protrudes downward and can effectively block the radial airflow on the lower side of the outer barrel cover 500 and guide it to flow downward.

[0054] Preferably, in order to further improve the spoiler effect of the retaining rib 1, the following settings may be performed:

[0055] like Figures 1 to 3 and Figure 5 As shown, in this embodiment, the upper half of each retaining rib 1 is a vertical portion extending vertically up and down, and the lower half is an inclined portion which is gradually inclined from top to bottom away from the center of the outer barrel cover, and the extension length of the inclined portion in the radial direction of the annular outer barrel cover 500 is greater than the spacing distance between adjacent retaining ribs 1, so that the projection of each retaining rib 1 on the outer barrel cover 500 along the axial direction of the outer barrel cover 500 completely covers the loading port 2, so as to effectively shield the loading port 2 in the vertical direction up and down and prevent foreign objects from passing through and entering the gap between the inner and outer barrels.

[0056] like Figure 2As shown, in this embodiment, a plurality of openings can be opened on the outer drum cover 500, and a detachable water retaining member 600 is respectively provided at each opening, and a loading port 2 is respectively provided on each water retaining member 600, and a plurality of retaining ribs 1 protruding and extending downward are provided at the loading port 2; preferably, a water retaining member 600 is respectively provided on the left and right sides of the annular outer drum cover 500, and the two water retaining members 600 are symmetrically arranged, so that the washing machine can take in water from the left and right sides of the annular outer drum cover 500, and the retaining ribs 1 on both sides can block the airflow in different radial directions, so as to effectively improve the efficiency of blocking the rotating wind, and thereby effectively prevent the additives between the inner and outer drums from flowing into the inner drum with the rotating airflow.

[0057] In this embodiment, a hook similar to an eagle's beak is provided at the top of the outermost edge of the water retaining member 600, and the hook is used to cooperate with the seat on the edge of the outer barrel cover 500 to achieve the purpose of the two being connected by snapping; at the same time, a protruding limit block is provided on the inner edge of the bottom wall of the water retaining member 600, and the limit block is mainly stuck in the limit hole provided on the outer barrel cover 500. In this way, when the washing machine is running, the water retaining member 600 will be more stable and will not loosen. At the same time, in order to avoid a small amount of detergent, washing powder and other additives hanging on the outer barrel cover 500, especially to prevent them from hanging on the water retaining member 600, the water retaining member 600 is specially designed to be connected by such a snap hook; at the same time, the above-mentioned snap hook structure can also be easily disassembled, so that the user can selectively replace it according to their own needs, clean it, and then install it on the outer barrel cover 500 for use.

[0058] In the present embodiment, the water retaining member 600 is detachably mounted on the outer barrel cover 500 so that the user can remove it from the outer barrel cover 2 for cleaning. Preferably, the upper side of the outer barrel cover 2 is provided with a mounting position corresponding to the water retaining member 600, and the water retaining member 600 is arranged to enter the mounting position in a movable manner. As a preferred embodiment, the mounting position includes a slideway so that the water retaining member 600 can slide into the mounting position by the slideway. Preferably, the slideway is oppositely arranged on the upper side surface of the outer barrel cover 500 to form a accommodating cavity matching the shape of the water retaining member 600. In the present embodiment, when the water retaining member 600 is mounted on the outer barrel cover 500, the two ends of the water retaining member 600 are respectively aligned with the slideway, and then the water retaining member is pushed toward the inner end of the slideway so that the water retaining member 600 slides into the above-mentioned accommodating cavity along the slideway to complete the fixation of the water retaining member and the outer barrel cover 500.

[0059] In order to facilitate the user to remove the water retaining member, preferably, the water retaining member 600 is provided with an operating end, for example, the operating end is a handle provided on the outside of the water retaining member, so that the user can remove the water retaining member 600 from the outer barrel cover 500 through the operating end. Specifically, the operating end is a plate-like structure with a certain length extending from the upper end of the side wall of the water retaining member 600, and the plate-like structure protrudes outward relative to the highest point of the side wall, so that the user can pull the water retaining member 600 out of the guide groove by holding the plate-like structure. Of course, the water retaining member 600 can also be arranged to protrude outward relative to the outer ring edge of the outer barrel cover 500, which can further facilitate the user's operation.

[0060] Embodiment 2

[0061] The difference between this embodiment and the above embodiment is that:

[0063] Similarly, in this embodiment, in order to enhance the effective shielding of different radial airflows, a plurality of delivery ports 2 in different radial directions may be provided on the outer barrel cover 500, and each delivery port 2 is provided with a downwardly protruding retaining rib 1, and the retaining rib 1 is staggered with the radial direction of the annular outer barrel cover to achieve the purpose of effectively shielding the airflows in different radial directions and guiding them to flow downwardly back into between the inner and outer barrels.

[0064] Embodiment 3

[0065] This embodiment is based on the above-mentioned embodiments 1 and 2 and also has the following technical features:
