DETAILED DESCRIPTION

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0047] Embodiment 1, as Figures 1 to 16 As shown, an assembly structure of an inner liner and a door frame includes an inner liner 2 and a door frame 1, wherein the inner liner 2 includes an inner liner side wall 21 and an inner liner rear wall 22 which are integrally formed, wherein the inner liner rear wall 22 is vertically arranged at the rear side of the inner liner 2, wherein the inner liner side wall 21 is located at the left and right ends of the inner liner rear wall 22, wherein the inner liner side wall 21 and the inner liner rear wall 22 are vertically arranged, wherein a top plate 3 is arranged on the upper side of the inner liner 2, wherein the front edge of the inner liner side wall 21 is referred to as a side wall front edge 211, the lower edge is referred to as a side wall lower edge 212, and the front edge of the top plate 3 is referred to as a top plate front edge 31, wherein the door frame 1 includes a first door frame 11, a second door frame 1 2 and a third door frame 13, the first door frame 11 is arranged in the vertical direction and is clamped with the front edge 211 of the side wall; the second door frame 12 is arranged at the upper end of the first door frame 11 in the horizontal direction and is clamped with the front edge 31 of the top plate; the third door frame 13 is arranged at the lower end of the first door frame 11 in the horizontal direction and is clamped with the lower edge 212 of the side wall; the door frame 1 includes two first door frames 11 and two third door frames 13 respectively arranged in parallel, the two ends of the second door frame 12 are respectively connected to the upper end of the first door frame 11, and the third door frame 13 is arranged perpendicular to the first door frame 11 and the second door frame 12.

[0048] In the prior art, the inner tank of a dishwasher generally includes a top wall and left and right side walls, and a rear plate is separately provided at the rear of the inner tank, and the rear plate is mounted on the inner tank by welding or riveting. Since there is a gap at the connection between the rear plate and the inner tank, it is easy to leak. The present application changes the inner tank 2 into a structure consisting of an integrally formed inner tank rear wall 22 and inner tank side walls 21, so that there is no gap between the rear side surface and the left and right side surfaces inside the dishwasher, thereby avoiding the problem of easy leakage at the connection between the rear plate and the inner tank.

[0049] Specifically, during the use of the dishwasher, if water is directly sprayed down from the upper inner part of the dishwasher, the inner upper surface of the dishwasher, and the connection between the upper surface and the rear side, and the upper surface and the left and right side walls are basically not in contact with the washing water, and the risk of water leakage is low, while the connection between the rear side and the left and right side walls of the dishwasher will continue to have water flowing down, and the risk of water leakage is high; furthermore, if water is sprayed upward from the bottom of the dishwasher and then flows back to the bottom, the water will fall directly after being sprayed to the upper surface of the dishwasher, and the inner upper surface of the dishwasher, and the connection between the upper surface and the rear side, and the left and right side walls will be in contact with water for a very short time, and the risk of water leakage is also low. However, whether the water flows upward or downward, the water will flow down along the inner rear side and the left and right side walls of the dishwasher for a long time, especially the connection between the inner rear side and the left and right side walls of the dishwasher, which has a large amount of water contact and a long contact time with the water flow, and the risk of water leakage is high. The present application adjusts the structure of the inner tank 2 and sets the inner tank 2 to be composed of an integrally formed inner tank side wall 21 and an inner tank rear wall 22, so that there is no gap at the connection between the inner rear side and the left and right sides of the dishwasher, fundamentally solving the problem of water leakage at the connection between the inner rear side and the left and right sides of the dishwasher, and the structure of the inner tank 2 is simple and can be directly obtained by changing the placement direction of the existing inner tank.

[0050] During assembly, first place the inner liner 2 on the third door frame 13, and slide the inner liner 2 along the third door frame 13 so that the lower edge 212 of the side wall of the inner liner 2 is inserted into the third door frame 13, and then continue to push the inner liner 2 so that the front edge 211 of the side wall of the inner liner 2 is inserted into the first door frame 11, and the assembly of the inner liner 2 is completed, which is convenient and quick.

[0051] After the inner tank 2 is changed to be composed of an inner tank side wall 21 and an inner tank rear wall 22, although the problem of water leakage inside the dishwasher is improved, due to the absence of an integrally formed inner tank top wall, the supporting capacity and stability of the inner tank 2 are reduced. By setting the door frame 1 as a first door frame 11 and a third door frame 13, on the one hand, the door of the dishwasher can be installed on the inner tank 2 through the first door frame 11, and on the other hand, the door frame 1 is connected to the lower edge 212 of the side wall of the inner tank side wall 21 through the third door frame 13, which can improve the strength and stability of the inner tank 2, especially the stability of the inner tank side wall 21, and avoid deformation of the inner tank 2. At the same time, the lower edge 212 of the side wall of the inner tank side wall 21 can be connected and sealed through the third door frame 13 to avoid water leakage at the lower edge 212 of the side wall of the inner tank side wall 21.

[0052] Furthermore, the top plate 3 and the inner liner 2 are integrally formed.

[0053] Since the contact time between the inner upper surface of the dishwasher and the washing water is short, after the water contacts the inner upper surface of the dishwasher, most of it falls directly, and a small part of it spreads to the connection between the inner upper surface of the dishwasher and the rear side and the left and right sides. Therefore, a top plate 3 can be set on the upper side of the inner tank 2 to play a supporting and sealing role. Furthermore, the top plate 3 and the inner tank 2 are integrally formed, which can further reduce the possibility of water leakage in the dishwasher, and at the same time, simplify the preparation process, reduce the number of parts, reduce assembly steps, and improve assembly efficiency.

[0054] During assembly, it is only necessary to push the inner liner 2 forward along the third door frame 13 from the rear side of the inner liner 2, insert the lower edge 212 of the inner liner side wall 21 into the third door frame 13, insert the side wall front edge 211 of the inner liner side wall 21 into the first door frame 11, and insert the top plate front edge 31 of the top plate 3 into the second door frame 12 to complete the assembly of the inner liner 2, the top plate 3 and the door frame 1, which is very convenient.

[0055] In addition, by setting the first door frame 11, the second door frame 12 and the third door frame 13, the door frame 1, the inner tank 2 and the top plate 3 can be connected to each other, so that the door frame 1, the inner tank 2 and the top plate 3 can cooperate and support each other, further improving the assembly stability of the inner tank 2 and the door frame 1 of the dishwasher.

[0056] Further, such as Figures 3 to 5 As shown, the third door frame 13 is provided with a sliding post 131 with a semi-cylindrical cross section, and a sliding groove 213 is provided on the side wall lower edge 212 of the inner liner side wall 21, and the inner side cross section of the sliding groove 213 is a semi-circular shape corresponding to the sliding post 131. During assembly, the sliding groove 213 only needs to be clamped on the sliding post 131, and then the inner liner side wall 21 is pushed along the sliding post 131, so that the inner liner side wall 21 and the third door frame 13 can be clamped.

[0057] In addition, a semi-cylindrical sliding column 131 is provided on the third door frame 13, and a sliding groove 213 is provided on the lower edge 212 of the side wall of the inner liner side wall 21. After assembly, the sliding column 131 can play a barrier role, making it difficult for water inside the inner liner 2 to leak to the outside of the inner liner 2 through the sliding column 131 and the sliding groove 213.

[0058] Furthermore, the curvature of the slide post 131 is greater than 180°, and correspondingly, the curvature of the slide groove 213 is also greater than 180°. In this way, both sides of the slide groove 213 need to be deformed to be snap-fitted with the slide post 131. A certain snap-fitting force can be generated between the slide post 131 and the slide groove 213, so that the snap-fitting between the slide post 131 and the slide groove 213 is very stable.

[0059] Preferably, a water guide groove 132 is provided on the inner side of the inner tank 2 along the extension direction of the slide column 131 , and the water guide groove 132 is connected to the drainage mechanism in the dishwasher. The setting of the water guide groove 132 enables the water flowing down the side wall 21 of the inner tank to be quickly discharged through the water guide groove 132 .

[0060] More preferably, a drainage hole 133 is provided at the bottom of the water guide groove 132 , and the drainage hole 133 is a through hole, and the drainage hole 133 is connected to a drainage mechanism in the dishwasher.

[0061] Further, such as Figures 6 to 12 As shown, an inserting portion 4 is provided on the top plate front edge 31 of the top plate 3 and the side wall front edge 211 of the inner liner side wall 21 , and a clamping portion 5 is provided on the first door frame 11 and the second door frame 12 , and the inserting portion 4 is clamped with the clamping portion 5 .

[0062] Of course, the clamping portion 5 can also be arranged on the top plate front edge 31 of the top plate 3 and the side wall front edge 211 of the inner container side wall 21 . At the same time, the plug-in portion 4 is located on the first door frame 11 and the second door frame 12 .

[0063] Furthermore, the plug-in portion 4 is in a "mountain" shape, and the clamping portion 5 is in a "U" shape, and the plug-in portion 4 and the clamping portion 5 can be clamped together.

[0064] Specifically, the plug-in portion 4 includes plug-in arms 42 located on both sides thereof and a plug-in column 41 located in the middle thereof, and the plug-in arms 42 and the plug-in column 41 extend in parallel in the same direction, so that the plug-in arms 42 on both sides can respectively form two grooves with the plug-in column 41; the clamping portion 5 includes two relatively arranged clamping arms 52, and a clamping groove 51 is formed between the two clamping arms 52. When the plug-in portion 4 is clamped with the clamping portion 5, the two clamping arms 52 can be respectively inserted into the two grooves formed by the plug-in arms 42 and the plug-in column 41, and the plug-in column 41 can be inserted into the clamping groove 51, so that the plug-in portion 4 and the clamping portion 5 can be staggered and clamped together.

[0065] The "mountain"-shaped structural design of the plug-in part 4 and the "U"-shaped structural design of the clamping part 5 can, on the one hand, ensure the clamping strength and stability of the plug-in part 4 and the clamping part 5; on the other hand, it can make the connection between the front edge 31 of the top plate and the second door frame 12, and the front edge 211 of the side wall and the first door frame 11 have good sealing properties, and washing water is not easy to leak through their connections.

[0066] Furthermore, the end of the plug-in column 41 has an expansion end with a circular cross-section, the snap-in groove 51 has a cylindrical accommodating cavity, and a guide portion 54 is provided at the end of the snap-in arm 52. The guide portion 54 is an inclined surface located on one side close to the snap-in groove 51. The two guide portions 54 are arranged in a trumpet shape on both sides of the snap-in groove 51. When the plug-in portion 4 is snap-connected with the snap-in portion 5, the guide portion 54 can guide the plug-in column 41, so that the plug-in column 41 is easily inserted into the snap-in groove 51.

[0067] Further, such as Fig.11 As shown, on the side of the clamping arm 52 away from the clamping groove 51, the two clamping arms 52 shrink inward to form two steps 53 on both sides of the clamping portion 5. When the plug-in portion 4 is clamped with the clamping portion 5, the two plug-in arms 42 of the plug-in portion 4 can fill and be plugged into the steps 53, so that the two side surfaces of the second door frame 12 and the first door frame 11 are flush with the two side surfaces of the plug-in portion 4, so that the combination of the plug-in portion 4 with the second door frame 12 and the first door frame 11 is tighter and more beautiful, and the sealing and waterproof properties are also better.

[0068] Furthermore, Fig.12 As shown, the two plug-in arms 42 of the plug-in portion 4 extend from the two side surfaces of the top plate 3 or the inner liner side wall 21, and the sides of the two plug-in arms 42 away from the plug-in column 41 are respectively flush with the inner and outer side surfaces of the top plate 3 or the inner liner side wall 21, and when the top plate 3 and the second door frame 12 or the inner liner side wall 21 and the first door frame 11 are snapped together, a smooth transition connection can be achieved between the top plate 3 and the second door frame 12 or the inner liner side wall 21 and the first door frame 11, thereby further improving the combination stability, aesthetics, and sealing and waterproof properties of the plug-in portion 4 with the second door frame 12 and the first door frame 11.

[0069] Furthermore, a locking hole 6 is provided at the junction of the plug-in portion 4 and the clamping portion 5, and the locking hole 6 passes through the plug-in arm 42, the clamping arm 52 and the plug-in column 41 in sequence from the outside of the inner liner 2 or the top plate 3, and a locking piece 7 is provided in the locking hole 6, and the locking piece 7 is a cylindrical structural piece provided corresponding to the locking hole 6.

[0070] As some embodiments of the present application, the locking hole 6 is a through hole, and the locking hole 6 extends from the inner side of the inner liner 2 or the top plate 3 to the outer side.

[0071] As some embodiments of the present application, the locking hole 6 is a blind hole, and the locking hole 6 extends from the outer side of the inner liner 2 or the top plate 3 to the plug-in column 41 .

[0072] The locking member 7 can be used to fix the interlaced and engaged plug-in portion 4 and the clamping portion 5 together to prevent the plug-in portion 4 and the clamping portion 5 from falling off or separating.

[0073] Furthermore, a snap-in groove 61 and a receiving groove 62 are provided on the side wall of the locking hole 6, and the receiving groove 62 is an annular groove provided on the side wall of the locking hole 6, and the snap-in groove 61 is a groove provided on the side wall of the locking hole 6 parallel to the axial direction of the locking hole 6, one end of the snap-in groove 61 is connected to the outer side of the inner liner 2 or the top plate 3, and the other end is connected to the receiving groove 62; correspondingly, the locking member 7 includes a cylindrical locking disk 71 and a fixing protrusion 72 located on the side wall of the locking disk 71, and the snap-in groove 61 and the fixing protrusion 72 are provided correspondingly.

[0074] During assembly, first insert the locking disk 71 into the locking hole 6, and at the same time, install the fixing protrusion 72 into the accommodating groove 62 through the snap-in groove 61, and then rotate the locking piece 7 so that the fixing protrusion 72 and the snap-in groove 61 are offset, and the installation of the locking piece 7 is completed. Afterwards, due to the crossing and pulling action of the plug-in portion 4 and the snap-in portion 5, the locking piece 7 will be fixed in the locking hole 6 and will not easily rotate or fall off.

[0075] Furthermore, a groove 73 is provided on the locking disk 71. When the locking member 7 and the locking hole 6 are assembled, the groove 73 is exposed on the outside of the top plate 3 or the inner tank side wall 21.
