[0030] like Figures 1-6 As shown, an external handle mounting structure for a dishwasher is disclosed. Applied to the dishwasher industry, it allows the door to be opened physically by prying open when the dishwasher system malfunctions and cannot be unlocked via program control. The structure includes a first cavity 1 within the door panel and an external handle 2 detachably mounted within the first cavity 1. The first cavity 1 contains a latching assembly 3 for securing the external handle 2. Specifically, the first cavity 1 is a recessed cavity, which can be located on the upper or lower part of the inner wall of the door panel near the edge, allowing the user to easily reach and remove the external handle 2 from the outside. In this invention, the first cavity 1 is located on the lower part of the door panel.

[0031] In this embodiment, as Figures 1-4As shown, the external handle 2 comprises a hand-holding section 21, a middle section 22 and a terminal section 23 connected in sequence, and the terminal section 23 is bent at an angle with the middle section 22. Specifically, the external handle 2 can be made of metal or strong plastic, and in the utility model, the external handle 2 is made of metal in one piece. The terminal section 23 is bent and its length is less than that of the middle section 22, so that the user can pry open the door panel by using the lever principle, which conforms to human mechanics.

[0032] Further, the hand-holding section 21 is in the shape of an oblong. When used, the fingers pass through the center of the hand-holding section 21 and hold it tightly, so as to implement the actions of pushing and pulling and rotating.

[0033] Further, the terminal section 23 is in the shape of a wide flat. It is convenient for the user to insert it into the gap between the door panel and the main body of the machine, so as to implement the physical door opening mode.

[0034] Further, the bending angle of the terminal section 23 with the middle section 22 is 80°-100°. As a preferred, the bending angle of the terminal section 23 with the middle section 22 is 90°, which is more labor-saving and more convenient for the user to quickly pry open the door panel.

[0035] As shown in Figure 1 , Figure 2 , Figure 5 The buckle assembly 3 is located on one side of the lower part of the first cavity 1, and the lower part of the other side is provided with a second cavity 11 communicating with the first cavity 1, and the external handle 2 is installed in the first cavity 1 through the buckle assembly 3 and part of it extends into the second cavity 11.

[0036] Further, in order to facilitate the taking and placing of the external handle 2, the buckle assembly 3 is inclined to the horizontal plane, and specifically, the end of the buckle assembly 3 close to the second cavity 11 is inclined upward by 10°-45° horizontally, and as a preferred, the end of the buckle assembly 3 close to the second cavity 11 is inclined upward by 15°.

[0037] The buckle assembly 3 comprises a first buckle 31, a second buckle 32 and an elastically movable check buckle 33. The check buckle 33 is located between the first buckle 31 and the second buckle 32 and its height is higher than that of the first buckle 31 and the second buckle 32.

[0038] Specifically, in order to make the connection between the buckle assembly 3 and the first cavity 1 more close and firm, so as to make the installation of the external handle 2 more stable, the buckle assembly 3 and the inner wall of the first cavity 1 are made in one piece.

[0039] Further, the first buckle 31 is provided with a first clamping groove 311, and the second buckle 32 is provided with a second clamping groove 321. The first clamping groove 311 and the second clamping groove 321 are both in the shape of an open upper circular arc and coaxially arranged. The inner diameter of the first clamping groove 311 and the second clamping groove 321 is adapted to the outer diameter of the middle section 22 of the external handle 2, so as to limit the downward movement of the external handle 2.

[0040] Further, as shown in Figure 6 , the first clamping groove 311 and the second clamping groove 321 are both provided with a support block 34 connected with the inner wall of the first mounting cavity 11, for supporting the first clamping groove 311 and the second clamping groove 321. When the external handle 2 is installed, the support block 34 can support the external handle 2 in the opposite direction of the downward force, so as to avoid damage to the first buckle 31 and the second buckle 32. The support block 34 is integrally formed with the first buckle 31 and the second buckle 32, and is fixedly connected with the inner wall of the first cavity 11.

[0041] As shown in Figure 5 , Figure 6 , the non-return buckle 33 comprises a movable clamping groove 331 and a non-return buckle elastic piece 332. The upper end of the non-return buckle elastic piece 332 is fixedly connected with the inner wall of the first cavity 1, and the lower end is elastically movable in the movable clamping groove 331. The lower part of the non-return buckle elastic piece 332 is provided with a limiting protrusion 333. The limiting protrusion 333 is in the shape of a triangle. Specifically, the limiting protrusion 333 is provided with an upwardly inclined lower sliding surface 334 and a downwardly inclined limiting surface 335. The limiting surface 335 abuts above the middle section 22 of the external handle 2, so as to limit the upward movement of the external handle 2.

[0042] Specifically, as shown in Figure 2 , Figure 3As shown, the height difference between the check buckle 33 and the first buckle 31 and the second buckle 32 is adapted to the outer diameter of the middle section 22 of the outer handle 2. When the outer handle 2 needs to be installed, the outer handle 2 is first tightly attached to the inner wall of the first cavity 1, and the lower end of the hand-holding section 21 is placed into the second cavity 11. At this time, the middle section 22 abuts against the lower sliding surface 334 of the check buckle spring 332, and the end close to the hand-holding section 21 abuts against the second buckle 32. By pressing the other end of the middle section 22, the middle section 22 is completely placed into the first first slot 311 and the second slot 321, and the overall outer handle 2 is limited in the downward direction and has a supporting effect. When pressed, the downward pressure of the middle section 22 pushes the limiting block 333, thereby driving the check buckle spring 332 to elastically move in the door plate direction in the movable slot 331, so that the outer handle 2 moves downward along the lower sliding surface 334 and enters the first slot 311 and the second slot 321. Subsequently, the check buckle spring 332 is elastically reset, and the limiting surface 335 of the limiting block 333 abuts against the outer wall of the middle section 22, thereby limiting the outer handle 2 in the upward direction and fixing the outer handle 2 in the first cavity 1.

[0043] Conversely, when the outer handle 2 needs to be taken out of the first cavity 1, the end of the outer handle 2 located at the end section 23 is pushed upward, so that it is separated from the limitation of the first slot 311 and the second slot 321, and the outer handle 2 can be taken out. Specifically, when the end section 23 is pushed upward, the outer wall of the middle section 22 moves upward and generates a pushing force on the limiting surface 335 of the check buckle spring 332, thereby generating a pressure on the check buckle spring 332 to elastically deform the check buckle spring 332 to elastically move in the door plate direction. At this time, the limiting effect of the limiting block 333 on the outer handle 2 disappears, and the outer handle 2 is elastically moved upward to separate from the limitation of the buckle assembly 3.

[0044] In addition, since the buckle assembly is inclined, when the outer handle 2 is taken out and placed, compared with the horizontal arrangement, the first buckle 31, the second buckle 32 and the check buckle 33 do not simultaneously apply resistance to the outer handle 2. In other words, the resistance of taking out and re-placing is reduced, so that users with less strength can easily take out and place.

[0045] Finally, it should be noted that the above only describes preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or equivalently replace some technical features, and any technical solutions obtained by logical analysis, reasoning or limited experiments on the basis of the existing technology according to the concept of the present application shall be within the scope of protection defined by the claims.
