Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, and in particular to an outer door and a door body used for a washing machine, and a washing machine. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, dishwashers are gradually widely used in people's daily lives. A dishwasher generally includes a base, an inner tank and a door assembly, and the base, the inner tank and the door assembly form a washing chamber of the dishwasher.

[0003] At present, the door assembly of a dishwasher with a side-opening door usually includes an inner door and an outer door connected to each other. When the door body is closed, the inner door is at least partially embedded in the inner tank of the dishwasher. As shown in the "Dishwasher" disclosed in the Chinese invention patent application with patent number CN201710681617.8 (publication number CN109381147A), it includes at least one door assembly; the door assembly includes an inner door panel and a glass door assembly, and the glass door assembly is detachably mounted on the inner door panel. The glass door assembly includes a support member and a glass panel, and the support member is used to support the glass panel along the extension direction of the support member. The glass door assembly also includes at least one mounting bracket located between the support member and the glass panel, and the mounting bracket is used to mount the glass panel on the inner door panel. The glass door assembly also includes an adhesive tape, and the glass panel is connected to the support member through the adhesive tape.

[0004] In this patent, the support member has an installation groove and a flange formed by bending forward, and the installation bracket is clamped in the installation groove. At least one limiting device is provided on the surface of the support member facing away from the inner door panel, and the limiting device is used to limit the movement of the installation bracket on the support member.

[0005] It can be seen from the drawings of the patent that the limiting device is a convex portion arranged on the support member, which limits the displacement of the mounting bracket by counteracting the mounting bracket. This will place relatively high requirements on the manufacturing accuracy of the mounting bracket, because if there is a size deviation of the mounting bracket, if the mounting bracket is large in size, it will cause the mounting bracket to interfere with the limiting device and cannot be installed on the support member; if the mounting bracket is small in size, it cannot counteract the limiting device, and the limiting device cannot limit the mounting bracket. Summary of the invention

[0006] The first technical problem to be solved by the present invention is to provide an outer door for a washing machine with improved installation stability of a bracket in view of the current status of the prior art.

[0007] The second technical problem to be solved by the present invention is to provide a door body using the above-mentioned outer door, which can be replaced, in view of the current status of the prior art.

[0008] The third technical problem to be solved by the present invention is to provide a cleaning machine using the above-mentioned door body in view of the current status of the prior art.

[0009] The technical solution adopted by the present invention to solve the first technical problem is: an outer door for a washing machine, comprising

[0010] panel;

[0011] A support plate is arranged at the rear side of the panel and connected to the panel, wherein the support plate at least partially abuts against the rear wall surface of the panel, and the support plate comprises a plate body, wherein the periphery of the plate body extends forward or backward to form a folded edge;

[0012] A bracket, mounted on the plate body;

[0013] The invention is characterized in that: a positioning piece is provided on one of the bracket and the plate body, and a positioning hole for inserting the positioning piece is provided on the other of the bracket and the plate body, and the positioning piece abuts against one of the wall surfaces of the positioning hole;

[0014] An elastic member that abuts against the folded edge is also provided at the edge of the bracket, and the elastic member enables the positioning member to always maintain a tendency to abut against one of the wall surfaces of the positioning hole.

[0015] One structural form of the positioning member is: the positioning hole is opened on the plate body, the positioning member is an insert provided on the bracket, one end of the insert is connected to the bracket, the other end is a free end, a step portion is provided on the free end, the step surface of the step portion abuts against one of the wall surfaces of the positioning hole, and the step of the step portion and the bracket abut against the two sides of the plate body respectively. The positioning member is in the form of an insert, has a simple structure, and can be inserted into the positioning hole, and is easy to operate.

[0016] In order to improve the strength of the insert, the bracket is provided with a hollow hole penetrating the wall thickness thereof, the insert is located outside the hollow hole and facing the hollow hole, and a reinforcing rib is provided between the insert and the wall of the hollow hole.

[0017] Another structural form of the positioning member is: the positioning member is an extension arm provided on the bracket and a buckle foot provided at the free end of the extension arm, the buckle foot is elastically deformed by being squeezed inward when passing through the positioning hole, and after the buckle foot passes through the positioning hole and returns to a natural state, the buckle foot buckles the wall surface of the plate body, and the extension arm abuts against the wall surface of the positioning hole. The buckle foot protrudes from the plane where the positioning hole is located to prevent the user from scratching his hand by touching the sharp edge of the positioning hole.

[0018] The elastic member can be a spring, but the spring is generally a metal member, which is relatively expensive. The elastic member is in the shape of a strip, and the two ends of the elastic member are spaced apart and connected to the bracket, so that the elastic member and the bracket together form a cavity that can produce elastic deformation. The elastic member of the present application has a simple structure and can be integrally formed with the bracket, which is easy to process and manufacture, and can be made of the same plastic material as the bracket.

[0019] In order to make the elastic member deform easily, the elastic member includes at least two side walls connected in sequence, and an angle is formed between two adjacent side walls.

[0020] In the above scheme, preferably, there are five side walls, which are respectively the first side wall, the second side wall, the third side wall, the fourth side wall and the fifth side wall, the starting end of the first side wall is connected to the bracket, the end of the fifth side wall is connected to the bracket, the starting end of the first side wall and the end of the fifth side wall are spaced apart, the other ends of the first side wall and the fifth side wall are inclined toward each other, the starting end of the second side wall and the end of the fourth side wall are inclined toward each other, and the third side wall extends along the length direction of the folded edge of the corresponding side and can abut against the folded edge. The third side wall abuts against the folded edge, which can increase the force-bearing area and further facilitate the deformation of the elastic member.

[0021] In order to further make the elastic member easy to deform and not easy to break, the center line of the third side wall is taken as the center line, the first side wall and the fifth side wall are symmetrically arranged on both sides of the center line, the second side wall and the fourth side wall are symmetrically arranged on both sides of the center line, the angle between the first side wall and the fifth side wall is an obtuse angle, the angle between the first side wall and the second side wall is an acute angle, and the angle between the second side wall and the third side wall is an acute angle. This structural form has good deformability of the elastic member.

[0022] The structure is compact, a groove with a notch facing the folded edge is provided at the edge of the bracket, and the elastic member is arranged in the groove. In a natural state, the elastic member is partially exposed outside the groove. In this way, when the bracket is installed on the plate body, the elastic member is basically in the groove, making the structure of the bracket compact and occupying a small space.

[0023] In order to further improve the stability of the bracket installed on the plate body, the free end of the folded edge is bent inward to form a flange, and the plate body, folded edge and flange together form an embedding groove located at the periphery of the support plate, and the edge of the bracket is embedded in the embedding groove. The embedding groove can play a role in positioning the bracket to a certain extent.

[0024] In order to improve the support strength of the support plate, there are four supports, all of which are L-shaped, and the plate body is square, and the four supports are respectively arranged at the four corners of the plate body. This arrangement of the supports has good support for the support plate.

[0025] Preferably, the middle part of the plate body protrudes forward to form a convex part, the middle part of the panel is pasted on the convex part and / or the periphery of the panel is pasted on the bracket. The convex part can not only enhance the strength of the support plate, but also can be used to paste the middle part of the glass, thereby improving the firmness of the glass pasted on the support plate.

[0026] In order to improve the aesthetics of the outer door, decorative strips are provided on the top wall and the left and right side walls of the support plate. The decorative strips have a U-shaped groove with a notch facing the support plate and partially covering the support plate.

[0027] In order to position the decorative strip and the support plate relative to each other, each decorative strip includes two first side edges arranged opposite to each other and a second side edge connected between the two first side edges, each of the first side edges is provided with a clamping protrusion, the support is provided with a clamping hole, the folded edge and the plate body are provided with perforations corresponding to the clamping holes, and the clamping protrusion passes through the corresponding perforations and is clamped in the clamping hole. The coordination of the clamping protrusion and the clamping hole can position the decorative strip, and the structure is simple.

[0028] In the above scheme, one way is: in order to facilitate the production of decorative strips, the top and side decorative strips are designed separately, the decorative strip arranged on the top of the support plate is called the top decorative strip, and the two support strips arranged on the left and right sides of the support plate are called side decorative strips. There is a gap between the upper end of the side decorative strip and the top decorative strip, and the bracket is provided with an insert that can be inserted in the gap. The insert is used to fill the gap between the side decorative strip and the top decorative strip, and plays the role of beautifying the seam.

[0029] In the above scheme, another way is: the decorative strip arranged on the top of the support plate is called the top decorative strip, and the two support strips arranged on the left and right sides of the support plate are called side decorative strips, and the two side decorative strips and the top decorative strip are formed in one piece. This method does not require seam beauty treatment.

[0030] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a door body using the above-mentioned outer door, characterized in that it also includes an inner door and a middle door located on the rear side of the outer door, the middle door is arranged between the inner door and the outer door, the top wall panel of the middle door is a display panel, and the outer door is detachably connected to the inner door and the middle door.

[0031] The technical solution adopted by the present invention to solve the above-mentioned third technical problem is: a cleaning machine using the above-mentioned door body, characterized in that it also includes an inner tank with an open front side, and the door body can be rotatably disposed on the front side of the inner tank to open or close the opening of the inner tank, and when the door body is closed, the inner door is at least partially embedded in the inner tank.

[0032] Compared with the prior art, the advantages of the present invention are as follows: 1. The present invention arranges an elastic member, so that under the action of the elastic member, it can ensure that the positioning member is against one of the walls of the positioning hole, thereby ensuring the firmness of the connection between the bracket and the support plate, allowing the bracket to have a certain deviation in size during production, because this part of the deviation will be compensated by the elastic member, ensuring that the positioning member is firmly installed in the positioning hole; in addition, compared with the screw connection method of the bracket and the support plate, the connection method of the bracket and the support plate of the present invention is simple; 2. Because the outer door of the present application can be detachably connected to the inner door and the middle door, and the top wall panel of the middle door is a display panel, replacing the outer door will not affect electrical components, etc., which is convenient for users to customize the required outer door.

[0046] like Figures 3~9 As shown, the outer door 2 includes a panel 21, a support plate 22 and a bracket 23. The panel 21 is provided with a handle 211 which may be detached. The support plate 22 is provided at the rear side of the panel 21 and connected to the panel 21. The support plate 22 at least partially abuts against the rear wall of the panel 21. The panel 21 is a glass panel.

[0047] The support plate 22 includes a plate body 221, the periphery of the plate body 221 extends backward to form a folded edge 222, the free end of the folded edge 222 is bent inward to form a flange 223, the middle part of the plate body 221 protrudes forward to form a convex part 224, the middle part of the panel 21 is pasted on the convex part 224, and the periphery of the panel 21 is pasted on the bracket 23. Of course, it is also possible to apply silicone only on the convex part 224 or the bracket 23, so that the panel 21 is only pasted on the convex part 224 or the bracket 23.

[0048] The plate body 221, the folded edge 222 and the flange 223 together form an embedding groove 225 located at the periphery of the support plate 22, and the edge of the bracket 23 is embedded in the embedding groove 225. In this embodiment, there are four brackets 23, all of which are L-shaped, and the plate body 221 is square. The four brackets 23 are respectively arranged at the four corners of the plate body 221.

[0049] The bracket 23 is mounted on the plate 221 in the following manner:

An elastic piece 5 abutting against the folded edge 222 is also provided at the edge of the bracket 23, and the elastic piece 5 makes the positioning piece always maintain a tendency to abut against one of the walls of the positioning hole 226.

[0051] In this embodiment, the positioning hole 226 is opened on the plate body 221, and the positioning member is an insert 231 arranged on the bracket 23. The bracket 23 is provided with a hollow hole 232 that penetrates its wall thickness. The insert 231 is located on the outside of the hollow hole 232 and faces the hollow hole 232. One end of the insert 231 is connected to the bracket 23, and the other end is a free end. A reinforcing rib 233 is provided between the insert 231 and the wall of the hollow hole 232.

[0052] A step portion 2311 is provided on the free end of the insert 231. When the insert 231 is inserted into the positioning hole 226, the step surface 23111 of the step portion 2311 abuts against one of the wall surfaces of the positioning hole 226, and the step 23112 of the step portion 2311 and the bracket 23 are respectively abutted against the two sides of the plate body 221.

[0053] like Fig. 9 As shown, a groove 234 with a notch facing the folded edge 222 is provided at the edge of the bracket 23, and the elastic member 5 is arranged in the groove 234. The elastic member 5 includes five side walls connected in sequence, and the five side walls are respectively a first side wall 51, a second side wall 52, a third side wall 53, a fourth side wall 54 and a fifth side wall 55. The starting end of the first side wall 51 is connected to the bracket 23, and the end of the fifth side wall 55 is connected to the bracket 23. The starting end of the first side wall 51 and the end of the fifth side wall 55 are spaced apart, and the five side walls and the bracket 23 together form a cavity 56 that can produce elastic deformation.
