Description

Technical Field

[0001] This invention belongs to the field of home appliance technology, and more specifically, relates to a door assembly for the inner liner of a drawer dishwasher. Background Technology

[0002] As people's living standards improve, more and more families are using dishwashers to wash dishes. Previously, front-loading dishwashers required users to bend over significantly or even squat to fully open the door, which was tiring. Furthermore, because there was no surrounding partition when placing dishes in a front-loading dishwasher, residual food or liquid could easily spill outside the dishwasher, resulting in a poor user experience. With the development of dishwasher technology, drawer-type dishwashers were invented. Drawer-type dishwashers use a pull-out door design, eliminating the need for bending over or squatting to open the dishwasher, making them more ergonomic. The surrounding partition design also prevents spills of residual food or liquid.

[0003] Drawer-type dishwashers include an inner tub, with a door located on the front wall of the inner tub. Traditionally, the inner tub was made of a single piece of injection-molded plastic, and the door was also integrally molded with the inner tub. Now, to improve the quality and lifespan of the inner tub, it is made of metal. How to securely connect the door to the metal inner tub is a problem that needs to be solved by those skilled in the art.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a door assembly for the inner liner of a drawer dishwasher.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a door assembly for the inner liner of a drawer dishwasher, including a door body, a support device provided at the bottom of the inner liner, and the door body being fixedly connected to the support device through a connecting structure.

[0007] The connection structure includes a first connecting arm, which extends toward the inner liner.

[0008] Preferably, the first connecting arms are disposed on opposite sides of the main body of the door.

[0009] Furthermore, the first connecting arm extends integrally or is spaced apart along the length direction of the connecting structure.

[0010] Furthermore, a limiting part is provided on the first connecting arm;

[0011] Preferably, the first limiting part is a limiting protrusion provided at one end of the connecting arm, and the limiting protrusion is connected to the support device by insertion.

[0012] The first connecting arm is also provided with a connecting part;

[0013] Preferably, the connecting portion is located at the end furthest from the limiting protrusion;

[0014] More preferably, the connecting portion is a connecting hole provided on the first connecting arm for inserting a connecting member.

[0015] Furthermore, the first connecting arm is provided with a connecting part, and the door body and the support device are fixedly connected by a snap-fit ​​structure. The connecting part is a snap-fit ​​protrusion or snap-fit ​​hole provided on the connecting arm.

[0016] Alternatively, the main body of the door and the supporting device are fixedly connected by a connector, and the connecting part is a connecting hole provided on the connecting arm for the connector to pass through.

[0017] Preferably, the snap-fit ​​boss or snap-fit ​​hole extends integrally along the length of the connecting arm;

[0018] Alternatively, the snap-fit ​​protrusions or snap-fit ​​holes may be spaced apart on the connecting arm along the length of the connecting arm.

[0019] Furthermore, the main body of the door and the connecting structure are integrally formed or detachably connected.

[0020] Furthermore, the connecting structure includes a second connecting arm that connects to the main body of the door, wherein the second connecting arm is integrally bent at one end of the first connecting arm.

[0021] Furthermore, the second connecting arm is provided with multiple connecting holes, and the second connecting arm is fastened to the door body by fasteners.

[0022] Furthermore, the door body has connecting surfaces on opposite sides that connect to the second connecting arm, and the connecting surfaces are integrally bent from the ends of the door body.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0024] The door body of this invention is firmly connected to the support device through a connecting structure, which prevents the door body from falling off due to loose connection. At the same time, it avoids the door body from vibrating and generating noise during the operation of the dishwasher, thus improving the user experience.

The inner liner assembly includes an inner liner 11, a bottom support 12, an outer side panel 16, a door assembly 15, and a support device 13.

[0047] Specifically, the inner liner 11 has a top-opening cavity for holding kitchen utensils to be cleaned. The bottom support 12 is located at the bottom of the inner liner 11 and supports and fixes it. On both sides of the inner liner 11 parallel to the stretching direction of the dishwasher, outer side panels 16 are provided for noise reduction and decoration. The upper part of the outer side panels 16 is connected to the sealing frame 14 set on the top surface of the inner liner 11. One side of the support device 16 is connected to the lower part of the outer side panels 16, and the other side is supported and connected to the bottom support 12. The door assembly 15 includes a door 152 and a door connector 151. The door 152 is located on the front side of the inner liner 11. The door 152 and the support device 16 are connected and fixed by the door connector 151. The support device 13 connects and fixes the door 152, outer side panels 16 and bottom support 12 into one unit, improving the integrated design of the dishwasher and facilitating assembly and installation. In order to facilitate the push-pull operation of the dishwasher, the dishwasher also includes a slide rail assembly set in the cabinet. The slide rail assembly includes a slide rail 2 and a slide rail support frame 24. The slide rail 2 is fixedly connected to the cabinet through the slide rail support frame 24. The support device 13 is provided with a slide rail assembly structure for installing the limiting slide rail. The inner liner assembly is slidably connected to the cabinet through the slide rail 2.

[0048] The dishwasher provided by this invention, by adopting the aforementioned support device, not only serves to support the base but also solves the problem of difficult assembly and connection between various components of existing drawer-type dishwashers. In addition, a slide rail mounting position is set on the support device, making it multi-functional and effectively improving the space utilization of the dishwasher.

[0049] The support device described in this invention includes a support body with an extended length. The support body has a support structure for supporting the base and an assembly structure for mounting and cooperating with the base and / or slide rail and / or door body and / or side plate and / or light guide column. The specific structure of the support structure and assembly structure of the support device, as well as their assembly relationship with the base, slide rail, door body, side plate and light guide column, will be described below with reference to Embodiments 1 to 5.

[0050] Example 1

[0051] This embodiment mainly describes in detail the specific structure of the support structure and assembly structure that cooperates with the base, as well as the assembly relationship between the support device and the base.

[0052] The following is a detailed description of the support structure of the support device and the base assembly structure.

[0053] Combination Figures 1 to 4The dishwasher's inner tub 11 has a base support 12 at its bottom, which supports the inner tub 11. Support devices 13 are symmetrically arranged on both sides of the base support 12, providing symmetrical support to ensure the stability of the inner tub. A slide rail 2 can be installed at the bottom of the support device. After the slide rail is installed, the inner tub assembly can be pushed and pulled by the slide rail to achieve a drawer-type dishwasher structure. The base is supported on the slide rail by the support devices. The support devices are located on both sides of the base support 12. Each support device 13 includes a first support device on one side and a second support device on the opposite side, with the two support devices symmetrically arranged.

[0054] Specifically, the support body has a support structure for supporting the base and a base assembly structure for assembling the base, such as... Figure 3 As shown, the support body includes a first support frame, the first support frame includes a first support plate 1325 extending a certain length, the support structure includes a support portion, the support portion includes a lower protrusion at an angle to the first support plate 1325, the lower protrusion is provided along at least part of the lower edge of the first support plate 1325, the lower protrusion is formed by the lower edge of the first support plate 1325 extending towards the bottom support, the lower protrusion includes a first support plane 1311 formed by the outward extension of the lower edge portion of one end of the first support plate.

[0055] like Figure 5 As shown, the assembly structure includes a base assembly structure, which includes a base positioning part disposed on the first support plane 1311 for assembly positioning. The base positioning part is disposed on the base support part and is used for assembly positioning to enhance the stability of the support part and prevent horizontal movement during the support process.

[0056] Furthermore, the base positioning part includes a positioning protrusion provided on the first support plane 1311; or, the base positioning part is a flange formed by bending the edge portion of the first support plane 1311 upwards; or, the base positioning part is a positioning groove provided on the first support plane; or, as... Figure 4 As shown, the base positioning part is a mounting hole 1312 formed on the first support plane 1311. The mounting hole 1312 is a threaded hole, which is connected by screws. It not only serves a positioning function, but also connects and fixes the support device and the base. Preferably, the number of mounting holes 1312 is at least two.

[0057] To improve assembly efficiency and enhance positioning effectiveness, such as Figure 5As shown, the base positioning part further includes a positioning corner disposed at the corner of the first support plane 1311. The positioning corner includes a first positioning surface 1313 and a second positioning surface 1314 perpendicularly disposed at the corner of the first support plane 1311, and the first positioning surface 1313 and the second positioning surface 1314 at least limit the horizontal displacement of the supported body in two directions.

[0058] To improve the stability of the connection between the support device and the base, such as Figure 7 As shown, the base support assembly structure includes claws 1315 spaced along the length of the support plate near the side wall of the base support. The cooperation between the claws 1315 and the base support 12 further improves the connection stability between the support device and the base support.

[0059] In another embodiment, the lower protrusion further includes a second support plane at the rear end of the support body or at the middle of the support body. The other end of the lower edge of the first support plate 1325 extends outward to form the second support plane. The first support plane and the second support plane are set at both the front and rear positions to enhance the stability of the support.

[0060] In another embodiment, the lower protrusion includes a support plane formed by the overall outward extension of the lower edge of the first support plate 1325, which extends to form a long strip-shaped support plane, further enhancing the stability of the support.

[0061] The following is a detailed description of the corresponding assembly structure of the support device for the base.

[0062] Combination Figure 4 and Figure 6 The inner liner base of this invention is the base itself. The base liner 12 is provided with a supporting structure. The base liner includes a front side wall 121, a left side wall 123, and a right side wall 122. The base liner body includes a base liner bottom wall and base liner side walls that circumferentially surround the base liner bottom wall. The supporting structure can be provided on the base liner bottom wall to receive supporting force from the bottom, or it can be provided on the base liner side wall, with the side wall having a corresponding structure to receive supporting force. Since the inside of the base liner needs to cooperate with the inner liner, the supporting structure is provided on the outside of the base liner side wall, or on the outside of the base liner bottom wall.

[0063] like Figure 4As shown, the bottom support sidewall includes a front sidewall 121, a left sidewall 123, a right sidewall 122, and a rear sidewall. The front sidewall 121 is located near the door body 152, and the rear sidewall is located opposite the front sidewall 121. The left sidewall 123 and the right sidewall 122 connect the front sidewall and the rear sidewall, respectively. The supporting structure is provided on at least two sidewalls. In a preferred embodiment, the supporting structure is provided on at least the front sidewall 121. The front sidewall 121 can cooperate with the rear sidewall to form a supporting structure, or it can cooperate with the left sidewall 123 and the right sidewall 122 to form a supporting structure.

[0064] As shown in Figure 4, the front sidewall 121 is provided with a first support mating part 1211. The first support mating part 1211 includes a horizontally arranged first support mating surface 12111. The horizontal arrangement of the first support mating surface 12111 can receive the upward support force, ensuring a more stable support process. In order to ensure the balance of the base 12 in the left and right directions and to facilitate assembly, symmetrical structures are provided on both sides of the front sidewall. The first support mating part 1211 includes a left support mating part located at the end of the front sidewall 121 near the left sidewall 123 and a right support mating part located at the end of the front sidewall 121 near the right sidewall 122.

[0065] The following example only illustrates the right support mating part. The first support mating surface of the right support mating part extends away from the front side wall and towards the right side wall to form a positioning flange. The first support mating surface is generally L-shaped, but it can also be other irregular positioning structures, so as to facilitate installation and positioning during the assembly process. The structure connected to it can be quickly positioned to the fixed connection structure and then assembled for fixed connection.

[0066] like Figure 6 As shown, a first positioning mating surface 12112 and a second positioning mating surface 12113 are also provided at the edge of the positioning flange, which can form a mating stop with other connecting structures to better achieve the positioning function.

[0067] like Figure 6 As shown, the first supporting mating surface 12111 is provided with mounting holes. These mounting holes can also be provided on other connecting surfaces, as long as they can form a fixed mating structure with other structures. To ensure a stable mounting structure and prevent the base from detaching, at least two mounting holes are provided to create a robust structure.

[0068] The right side wall is provided with a second support mating part. In one embodiment, the second support mating part is at the same height as the first support mating surface and is horizontally arranged. The left side wall 123 and the right side wall 122 are symmetrically arranged. The second support mating structure can work together with the support mating structure of the front side wall to make the base support more stable.

[0069] like Figure 7 As shown, the right side wall 122 is provided with a second support mating part, and one or more slots 1221 are evenly provided on the right side wall 122 in the horizontal direction. This structure can achieve both positioning and support functions. At the top edge of the right side wall, a rolled edge structure can also be provided to ensure that other connecting structures cannot fall off from the top after mating with the slots, making the overall connection more stable.

[0070] Another implementation is that the bottom wall of the base is horizontally positioned near the edge of the left side wall 123 / right side wall 122 to form a support mating position. The bottom wall of the base is provided with mounting holes, or the left side wall 1223 / right side wall 122 is provided with mounting holes to form a connection that fits tightly with other connecting structures and can play a better supporting role. The support area is larger and can also save space inside the dishwasher.

[0071] The following is a detailed description of the assembly relationship between the base and the support device.

[0072] like Figures 1 to 7 As shown, the bottom of the inner tub 11 of the dishwasher is provided with a base support 12, which is used to support the inner tub 11. The support device 13 has a support part connected to the base support 12. The support device includes a first support device and a second support device arranged on both sides of the base support 12. The support devices are symmetrically arranged on both sides of the base support 12 to generate symmetrical support force on the base support, so as to ensure the stability of the inner tub.

[0073] Furthermore, the support device includes a support body, the support body includes a first support frame, the support frame includes a first support plate 1325 extending a certain length, the support portion includes a downward protrusion at an angle to the first support plate 1325, and the base 12 is provided with a support mating portion corresponding to the support portion.

[0074] Furthermore, the lower protrusion includes a first support plane 1311 extending from the bottom front end of the support body towards the base. The support mating part includes a first support mating part 1211 disposed on the front side wall 121 of the base. The first support mating part 1211 extends to form a first support mating surface 12111 corresponding to the first support plane 1311. The first support plane 1311 is supported on the lower surface of the first support mating surface 12111. The support area is increased through surface contact, so that the support device has a greater support force on the base.

[0075] Furthermore, a base positioning part is provided on the first support plane 1311, and a positioning mating part is correspondingly provided on the first support mating surface 12111. The positioning part and the positioning mating part cooperate with each other to prevent the first support plane 1311 of the support device from being misaligned and separated from the first support mating surface 12111 of the support device during the process of pushing and pulling the dishwasher, thereby playing a positioning role.

[0076] Specifically, the base support positioning part is a positioning protrusion provided on the first support plane 1311, and the positioning mating part is a positioning groove provided on the first support mating surface 12111; the positioning mating of the base support 12 and the support device 13 is achieved through the concave-convex mating method, which is simple to form.

[0077] Alternatively, the bottom support positioning part is a flange formed by bending the edge of the first support plane 1311 upwards, and the positioning mating part is an insertion groove opened on the first support mating surface 12111 corresponding to the flange. The positioning stability is stronger by insertion than by convex-concave mating.

[0078] In another embodiment, the base positioning part is a mounting hole 1312 opened on the first support plane 1311, and the positioning mating part is a base mounting hole opened on the first support mating surface 12111. The base and the support device are connected and fixed by screws or buckles.

[0079] Preferably, the base positioning part further includes a first positioning corner disposed on the first support plane 1311, and the first positioning mating part includes a second positioning corner disposed on the first support mating surface 12111 corresponding to the positioning corner. The second positioning corner includes a first positioning mating surface 12112 and a second positioning mating surface 12113. The outer wall surface of the second positioning corner matches the shape of the inner wall surface of the first positioning corner, that is, the outer wall surface of the first positioning mating surface 12112 and the second positioning mating surface 12113 matches the shape of the inner wall surface of the first positioning surface 1313 and the second positioning surface 1314. The first positioning corner and the second positioning corner form a mating stop, better realizing the positioning function, and their shape can also be other irregular structures.

[0080] In another embodiment, the support portion further includes a second support plane extending from the lower edge of the other end of the first support plate 1325 towards the base 12. The support mating portion also includes a second support mating portion, which includes a second support mating surface extending corresponding to the second support plane. The first support plane 1311 and the second support plane are respectively supported on the lower surfaces of the first support mating surface 12111 and the second support mating surface. The second support plane can be located at the rear end of the first support plate 1325, or at other positions in the middle of the first support plate 1325. The second support mating surface is correspondingly located on the rear side wall or left and right side walls of the base. By setting two support planes at a certain distance, the stability of the support device for the base is improved.

[0081] In another embodiment, the support portion includes a long strip-shaped support plane formed by the lower edge of the first support plate 1325 extending integrally towards the base support 12. The support mating portion is a first support mating surface formed by the side wall of the base support extending corresponding to the support plane, and the support plane rests below the first support mating surface. The entire side of the base support is supported by the support device, resulting in greater stability.

[0082] The support part also includes claws 1315 evenly spaced along the length of the first support plate 1325 on the side wall of the first support plate 1325 near the base 12. The support mating part also includes one or more slots 1221 evenly spaced along the right side wall 122 of the base 12. During assembly, the claws 1315 are inserted into the slots 1221 for easy positioning, so as to achieve a stable fit between the support device and the base, and the installation and disassembly are simple.

[0083] Example 2

[0084] This embodiment mainly describes in detail the specific structure of the slide rail assembly structure that cooperates with the support device and the slide rail, as well as its assembly relationship with the slide rail.

[0085] The following is a detailed description of the slide rail assembly structure of the support device:

[0086] like Figures 8 to 10 As shown, the support device provided in this embodiment includes a support body with an extended length. The support body has an assembly structure, which includes a slide rail assembly structure. The slide rail assembly structure is a slide rail mounting position disposed below the support body. Preferably, the slide rail mounting position is a slide rail mounting groove 1321 that passes through the support body. The slide rail mounting groove 1321 is a concave groove with its opening facing downwards, and the shape of the inner wall of the concave groove matches the shape of the outer surface of the slide rail.

[0087] like Figure 3 and Figure 4 As shown, the support body includes a first support frame, which includes a first support plate 1325 with a certain extension length, a second support plate 1326 parallel to the first support plate 1325, and a top plate 1327 connected to the upper surfaces of the first support plate 1325 and the second support plate 1326. The top plate 1327, the first support plate 1325, and the second support plate 1326 form the slide rail mounting groove 1321. Multiple arched ribs 13211 are spaced apart along the length of the slide rail mounting groove 1321 inside the slide rail mounting groove 1321 to reduce the overall weight of the support device 13 and better limit the movement of the slide rail.

[0088] Furthermore, the slide rail assembly structure also includes a first slide rail connecting part and a second slide rail connecting part for limiting the sliding direction and / or vertical displacement of the slide rail. The first slide rail connecting part is located at the front end of the slide rail mounting groove 1321, and the second slide rail connecting part is located at the rear end of the slide rail mounting groove 1321, so as to achieve more effective connection and fixation of the slide rail at both the front and rear positions.

[0089] Furthermore, such as Figure 8 As shown, the first slide rail connection part includes a limiting notch 1324 provided on the front end of the slide rail mounting groove 1321. The limiting notch 1324 is a notch provided at the front corner of the first support plate 1325 / second support plate 1326. The limiting notch 1324 is used to limit the displacement in the sliding pushing direction of the slide rail.

[0090] Furthermore, the first slide rail connection portion also includes a support portion 1323 for supporting the slide rail disposed below the slide rail mounting groove 1321. The side of the first support plate 1325 extends horizontally to form a first vertical connecting wall. The side of the first vertical connecting wall extends along its lower part towards the outer wall of the slide rail mounting groove 1321 to form the support portion 1323.

[0091] Furthermore, such as Figure 8As shown, the support portion 1323 includes a first slide rail support wall formed by a first vertical extension wall extending horizontally outward from the bottom side edge of the first vertical extension wall. The side end of the first slide rail support wall is bent outward to form a second slide rail support wall. The heights of the first and second slide rail support walls are lower than the height of the first support plate 1325, thus achieving the purpose of supporting the slide rail. The top surface of the second slide rail support wall extends outward to form a slide rail support surface, increasing the support area. In this embodiment, the first slide rail support wall is the first positioning surface 1313 of the positioning corner in Embodiment 1, and the second slide rail support wall is the second positioning surface 1314 of the positioning corner. The support portion 1323 restricts the downward displacement of the slide rail within the slide rail mounting groove 1321, thus supporting the front end of the slide rail. The support portion 1323 can also be formed by directly bending and extending inward from the lower side edge of the first support plate 1325.

[0092] Furthermore, such as Figure 8 As shown, the second slide rail connecting part includes a hook plate 1322 disposed at the rear end of the slide rail mounting groove 1321. The hook plate 1322 is horizontally connected to the top plate 1327 of the slide rail mounting groove 1321. The rear end of the slide rail is hooked onto the hook plate 1322. The hook plate 1322 serves to connect and fix the slide rail, and also serves to limit the downward displacement of the rear end of the slide rail within the slide rail mounting groove 1321.

[0093] Preferably, the second support plate 1326 at the rear end of the slide rail mounting groove 1321 extends horizontally to form a second vertical extension wall. One side edge of the hook plate 1322 is horizontally connected to the top wall of the slide rail mounting groove 1321, and the adjacent other side edge is connected to the inner wall of the second vertical extension wall. The two edges of the hook plate 1322 are connected and fixed to enhance the stability of the hook plate 1322 and prevent shaking or falling off, which would affect the pushing and pulling of the slide rail.

[0094] Preferably, such as Figure 9 As shown, the second slide rail connection part also includes a limiting mechanism disposed at the rear end of the slide rail mounting groove 1321 to limit the displacement of the slide rail in the sliding pushing direction. The limiting mechanism is a limiting rod 135 arranged horizontally in the transverse direction.

[0095] Preferably, the limiting mechanism includes a horizontally placed concave limiting frame, the opening of which faces the slide rail mounting groove 1321, the middle horizontal edge of which is the limiting rod 135, and the side of which is integrally formed with the hook plate 1322, thus simplifying the structure.

[0096] The following is a detailed description of the corresponding assembly structure and assembly relationship of the slide rail and support device.

[0097] like Figure 8 As shown, the slide rail 2 includes an upper sliding member 21 and a lower sliding member 22 that can move relative to each other. Generally, the upper sliding member 21 moves synchronously with the inner liner assembly, and the lower sliding member is fixedly connected to the box body. A middle sliding member 22 is also provided between the upper sliding member 21 and the lower sliding member 23. The upper sliding member 21 has a groove structure with an opening facing downwards, and the lower sliding member has a groove structure with an opening facing upwards. The middle sliding member is respectively limited to the upper sliding member 21 and the lower sliding member 23, and can slide relative to both.

[0098] The inner liner assembly is fixedly installed to the upper sliding member 21 via the support device 13. Correspondingly, the drawer assembly includes two sets of symmetrically arranged slide rails, and the support device 13 includes a first support device and a second support device that respectively cooperate with the two sets of slide rails. The following description focuses only on the cooperation between the first support device and the slide rails.

[0099] like Figure 8 As shown, the upper sliding member 21 of the slide rail 2 has a long strip structure. In order to ensure that the inner liner is more stably set on the slide rail 2, the support device also has a slide rail mounting position formed by the slide rail limiting part with a length equivalent to that of the slide rail 2. The slide rail mounting position is a groove-shaped slide rail mounting groove with the opening facing downward. The cross-sectional shape of the groove matches the outer surface shape of the upper sliding member. Due to the matching relationship between the slide rail mounting position and the upper sliding member 21, when the upper sliding member 21 is inserted into the slide rail mounting position, each side wall of the slide rail mounting position is tightly attached to the upper sliding member, which can restrict the relative movement of the upper sliding member 21 and the support device in the left and right directions.

[0100] like Figure 8 As shown, one end of the upper sliding member 21 is fixedly connected to the support device. The upper surface of one end of the upper sliding member 21 is provided with a hanging ear 211. The hanging ear is a structure that extends upward and then forward, with the opening facing forward. The support device is provided with a hook plate 1322 that cooperates with the hanging ear 211. The hook plate 1322 is a horizontal surface. The hanging ear 211 hooks onto the hook plate 1322 from back to front, realizing the connection between the two at the rear. This can limit the vertical displacement and limit the support plate from moving behind the slide rail.

[0101] like Figure 8 As shown, one end of the front part of the upper sliding member 21 is fixedly connected to the support device, and the other end of the upper sliding member 21 is provided with a detachable and fixedly connected end cap 212. The end cap 212 can be inserted into the groove of the upper sliding member 21 in a horizontal direction and is fixedly connected to the upper sliding member 21. Specifically, the top of the other end of the upper sliding member 21 has a bayonet, the end cap has an insertion end, the insertion end has an end cap buckle 2123 that matches the bayonet, and the insertion end of the end cap is inserted into the other end of the upper sliding member 21 and fixedly installed by the end cap buckle.

[0102] like Figure 8 As shown, the end cap 212 is stopped and abutted by the support device. The end cap is provided with a limiting protrusion 2121 perpendicular to the sliding direction of the slide rail. The support device has a limiting notch 1324 to avoid the limiting protrusion. The limiting protrusion 2121 and the limiting notch 1324 abut and limit each other at their edges to restrict the relative movement of the end cap 212 and the support device 13.

[0103] The end cap has a support groove 2122 at its bottom, and the support device has a support part 1323 on the side facing the end cap. The support part 1323 and the support groove 2122 abut against and support the end cap 212, thereby limiting the relative vertical movement of the end cap and the support device.

[0104] During assembly, the slide rail is first hooked onto the rear end of the support device via the rear lugs. At this point, the slide rail is also placed into the slide rail mounting slot. Then, the front end cap secures the slide rail, completing the assembly process between the slide rail and the support device. After assembly, since the upper sliding member can slide relative to the lower sliding member, certain limiting mechanisms are needed to prevent the slide rail from slipping. The slide rail also includes a fixedly mounted slide rail support frame 24. A limiting mechanism is provided between the slide rail support frame 24 and the support device 13 to limit the extreme positions when the support device is pushed in.

[0105] like Figure 8 As shown, the limiting mechanism includes a limiting member 25 mounted on the slide rail support frame. The limiting member 25 includes a pawl that can swing back and forth within a certain angle range. The limiting member 25 can be composed of two parts: a first part fixedly connected to the slide rail support frame, and a second part with a pawl rotatably mounted on the first part. The second part has a rotating shaft, and the first part has a rotating shaft groove to accommodate the rotating shaft. A protrusion is provided at the rear end of the first part to restrict further rearward rotation of the second part. A limiting rod 135, capable of engaging / disengaging from the pawl, is provided at the rear end of the support device. When the limiting rod 135 engages with the pawl and the pawl swings backward to its limit angle, the support device is pushed into its limit position. When the support device moves forward, the pawl first rotates a certain angle with the limiting rod. When it rotates to a certain angle, if the limiting rod continues to move forward, it will disengage from the pawl, and the pawl will remain in that position waiting for the limiting rod to engage with it again.

[0106] The dishwasher also includes a cabinet having an opening on the side, the drawer assembly being pushed and pulled from the opening side, and the slide rail including a slide rail support frame 24 fixedly connected to the inner side wall of the cabinet.

[0107] The drawer slides are fixedly connected to the support device via multiple directional limiting mechanisms, ensuring the overall fit between the slides and the inner liner assembly. This allows the drawer assembly to operate smoothly during pushing and pulling, protecting the tableware inside. The connection structures at the front and rear ends of the slides work together to facilitate easier assembly onto the support device. First, the rear end hook restricts the vertical movement of the slides and support device and prevents the support device from moving behind the slides. Then, the front end supports the support portion, further restricting the vertical movement of the slides and support device and preventing the support device from moving forward. These two mechanisms work together to limit the forward, backward, and vertical movement of the slides and support device, allowing for a secure connection while ensuring easy assembly. A limiting mechanism is also provided at the rear end of the support device. This limiting mechanism restricts the position of the inner liner assembly as it is pushed into the cabinet. Once a certain position is reached, the limiting mechanism prevents further movement of the inner liner assembly, protecting it from collision with the rear wall of the cabinet.

[0108] Example 3

[0109] This embodiment mainly describes in detail the specific structure of the door assembly structure in which the support device cooperates with the door body, as well as its assembly relationship with the door body.

[0110] The following is a detailed description of the door assembly structure of the support device:

[0111] In this embodiment, the supporting device includes a supporting body with an extended length, the supporting body having an assembly structure, and the assembly structure including a slide rail assembly structure. For example... Figures 9 to 11 As shown, the supporting body includes the first support frame described in Embodiment 2, and a second support frame fixedly connected to one end of the first support frame. The second support frame includes a vertical plate vertically disposed on one end of the first support frame, and the door assembly structure is disposed on the vertical plate. The door assembly structure disposed on the supporting device can also effectively solve the problem of assembling and connecting the bottom support and / or inner liner and / or outer panel with the door body.

[0112] Furthermore, such as Figure 12 As shown, the longitudinal plates include a first longitudinal plate 1331 and a second longitudinal plate arranged parallel to each other. A plate-like structure is provided above the first longitudinal plate 1331 and / or the second longitudinal plate, connected at a certain angle to the first longitudinal plate 1331 and / or the second longitudinal plate. The door assembly structure includes a positioning opening 1333 formed in the plate-like structure. The positioning opening 1333 restricts the movement of the door and reduces assembly difficulty. The plate-like structure can be provided separately on the first longitudinal plate 1331 or the second longitudinal plate. Preferably, the first longitudinal plate 1331 and the second longitudinal plate are arranged horizontally spaced apart, and the plate-like structure is connected between the first longitudinal plate 1331 and the second longitudinal plate to enhance the stability of the plate-like structure.

[0113] Furthermore, such as Figure 10 As shown, the vertical plate includes a third vertical plate 1361 that is parallel to the door body 152 and perpendicularly connected to the first vertical plate 1331. The second vertical plate includes an upper vertical plate 1362 disposed on the third vertical plate 1361. The plate-like structure connects the first vertical plate 1331 and the upper vertical plate 1362. By connecting the first vertical plate 1331 and the second vertical plate through the third vertical plate 1361, the stability between the first vertical plate 1331 and the second vertical plate can be effectively enhanced. At the same time, the upper vertical plate 1332 is a small section of plate disposed on the third vertical plate 1361, which not only does not affect the setting of the positioning opening 1333, but also saves materials and reduces material costs.

[0114] Preferably, the plate-like structure is partially gapped to the third longitudinal plate 1361, forming the positioning opening 1333. This gap allows the insertion part of the door assembly 15 to be inserted and positioned. The gapped connection between the plate-like structure and the third longitudinal plate 1361 further enhances the stability of the plate-like structure, preventing deformation and detachment of the plate-like structure during the insertion process, thus preventing the insertion part of the door assembly 15 from being difficult to insert into the positioning opening 1333. This further restricts the upward and / or forward / backward and left / right movement of the door and the supporting device.

[0115] Furthermore, such as Figure 12 As shown, the door assembly structure includes a first assembly hole on the first longitudinal plate 1331 and a second assembly hole on the second longitudinal plate. The door assembly 15 is fixed by fasteners, which pass through the first assembly hole on the first longitudinal plate 1331, the door assembly 15, and the second assembly hole on the second longitudinal plate in sequence, thereby fixing the door assembly 15 to the support device 13.

[0116] Preferably, the first mounting hole is located below the first vertical plate 1331, and the second vertical plate further includes a lower vertical plate 1332 connected to the first support frame. The second mounting hole is located on the lower vertical plate 1332 corresponding to the first mounting hole. The upper part of the door body 15 is limited and fixed by the positioning port 1333, and the lower part is fixed by bolts or buckles. The upper and lower limiting and fixing enhances the stability between the overall door body and the support device.

[0117] Furthermore, such as Figure 12 As shown, the first assembly hole is a first snap-fit ​​mounting hole 13311, and the second assembly hole is a second snap-fit ​​mounting hole 13321. The door assembly is fixed by snap-fit, which is simple to install, easy to disassemble and replace, and reduces the assembly difficulty.

[0118] Preferably, such as Figure 12As shown, the first buckle mounting hole 13311 is a square stepped countersunk hole, and the second buckle mounting hole 13321 is a circular hole. The end cap of the buckle is located inside the square stepped countersunk hole and is not exposed, preventing scratches to other parts and enhancing the overall aesthetics. More preferably, a positioning groove is provided in the stepped countersunk hole. The positioning groove effectively prevents the buckle from moving or detaching within the mounting hole and also reduces assembly difficulty. For ease of processing, the positioning groove is a through positioning groove formed in the stepped portion of the stepped countersunk hole. The through positioning groove is located in the middle of the upper, lower, left, and right walls of the stepped countersunk hole, providing comprehensive positioning from four directions and further preventing the buckle from moving or detaching within the mounting hole.

[0119] Furthermore, such as Figure 12 A reinforcing rib 1372 is provided between the first longitudinal plate 1331 and the third longitudinal plate 1361. Preferably, the reinforcing rib 1372 is in the shape of a right-angled trapezoidal plate. The right-angled side of the plate-shaped reinforcing rib 1372 is connected to the first longitudinal plate 1331, and the long side of the lower base of the plate-shaped reinforcing rib 1372 is connected to the inner wall of the third longitudinal plate 1361. The right-angled trapezoidal shape of the reinforcing rib 1372 not only plays a reinforcing role, but also saves a lot of material by setting it to a trapezoidal shape.

[0120] Furthermore, the second support frame also includes a reinforcing arm 1371 that is inclinedly connected between the upper end of the first longitudinal plate 1331 and the first support frame to enhance the stability of the second support frame.

[0121] The following is a detailed description of the door's structure.

[0122] like Figure 11-12 As shown, the door assembly 15 includes a door body 152, and a support device is provided at the bottom of the inner liner. The door body 152 is fixedly connected to the support device through a connecting structure. The connecting structure ensures a stable connection between the door body 152 and the support device, preventing the door body 152 from falling off and avoiding noise caused by vibration during dishwasher operation, thus improving the user experience. The door body connecting structure is as follows: Figure 10 The door connector 151 in the figure and the door body 152 in the figure are the main body of the door.

[0123] The connecting structure includes a first connecting arm 1511 disposed on the side of the door body 152 near the inner liner. Specifically, the first connecting arm 1511 is disposed on opposite sides of the door body 152. The placement of the first connecting arm 1511 ensures that the connection point between the door body 152 and the support device is located on the plane formed by the first connecting arm 1511, reducing the difficulty of connection. Furthermore, the placement of the first connecting arm 1511 on opposite sides of the door body 152 ensures that both ends of the door body 152 are fixedly connected to the support device, making the connection between the door body 152 and the support device more reliable.

[0124] Specifically, the first connecting arm 1511 extends integrally along the length of the connecting structure, making its molding and manufacturing simpler and increasing its connection strength with the support device. Alternatively, the first connecting arms 1511 are spaced apart along the length of the connecting structure, reducing the difficulty of connecting the first connecting arms 1511 to the support device and saving materials used in manufacturing the first connecting arms 1511.

[0125] The first connecting arm 1511 is provided with a limiting part. Specifically, the first limiting part is a limiting protrusion located at one end of the connecting arm, and the limiting protrusion is inserted and connected to the support device. The limiting protrusion is... Figure 11 The first limiting part is a U-shaped notch located at one end of the connecting arm. The first limiting part restricts the first connecting arm 1511 from the supporting device, while also positioning the supporting device and the door body 152 for installation, thus increasing installation efficiency.

[0126] The first connecting arm 1511 is also provided with a connecting portion; specifically, the connecting portion is located at the end away from the limiting protrusion; the connecting portion is a connecting hole on the first connecting arm 1511 for a connecting member to pass through. The connecting member is a snap-fit ​​member, and the connecting hole is a snap-fit ​​mounting hole. The snap-fit ​​member passes through the snap-fit ​​mounting hole to fix the main body of the door 152 and the supporting device. The snap-fit ​​mounting hole is... Figure 11 The third buckle mounting hole is 15112.

[0127] Alternatively, the first connecting arm 1511 may be provided with a connecting part, and the door body 152 and the support device may be fixedly connected by a snap-fit ​​structure. The connecting part may be a snap-fit ​​boss or a snap-fit ​​hole provided on the connecting arm. The door body 152 and the support device may be fixedly connected by a snap-fit ​​structure, eliminating the need for additional connectors, saving costs, and speeding up the connection and assembly process.

[0128] The snap-fit ​​boss or snap-fit ​​hole extends integrally along the length of the connecting arm; or the snap-fit ​​boss or snap-fit ​​hole is spaced apart along the length of the connecting arm. The snap-fit ​​boss is integrally injection molded onto the first connecting arm 1511, or the snap-fit ​​hole is integrally formed on the first connecting arm 1511. This simplifies the molding and manufacturing of the snap-fit ​​boss or snap-fit ​​hole, while the spaced-apart arrangement of the snap-fit ​​boss or snap-fit ​​hole along the length of the first connecting arm 1511 saves on manufacturing material and facilitates the assembly of the first connecting arm 1511 with the support device.

[0129] Alternatively, the door body 152 and the supporting device are fixedly connected by a connector, wherein the connecting part is a connecting hole on the connecting arm for the connector to pass through. The connector is a screw, which passes through the connecting hole on the first connecting arm 1511 to fasten the supporting device and the door body 152. Screws are standard parts and easy to purchase, eliminating the need to redesign a new connection structure; only a connecting hole needs to be made on the first connecting arm 1511, and the connection process is mature and reliable.

[0130] The door body 152 is integrally formed with the connecting structure or can be detachably connected. The integrally formed design increases the connection strength between the door body 152 and the connecting structure. The detachable design allows for easy assembly of the door body 152 and the support device, facilitating replacement and maintenance.

[0131] The connecting structure includes a second connecting arm 1512 that connects to the door body 152. The second connecting arm 1512 is formed by bending one end of the first connecting arm 1511. This increases the connection strength between the first connecting arm 1511 and the second connecting arm 1512, making the connection between the door body 152 and the support device more secure.

[0132] The second connecting arm 1512 is provided with multiple connecting holes, and the second connecting arm 1512 is fastened to the door body 152 by fasteners. The connecting component is a screw, which passes through the connecting holes on the second connecting arm 1512 to fasten the door body 152. Screws are standard parts and easy to purchase, eliminating the need to redesign a new connection structure; only connecting holes need to be made on the second connecting arm 1512, and the connection process is mature and reliable.

[0133] The main body of the door 152 has connecting surfaces on opposite sides that connect to the second connecting arm 1512. The connecting surfaces are integrally bent at the ends of the door 152.

[0134] Specifically, the dishwasher is equipped with a slide rail. The ends of the door body 152 near the opposite sides of the slide rail are bent towards the inner tub to form two first bends. The free ends of the two first bends are bent towards the opposite first bends to form two second bends. The second connecting arm 1512 overlaps with the inner wall of the second bends away from the inner tub and is then fastened by fasteners. When the door body 152 is opened, the second bends exert force on the second connecting arm 1512, but not on the fasteners, ensuring a reliable and stable connection between the door body 152 and the support device. The second bend is the door mounting part 1521 shown in the figure.

[0135] The following is a detailed description of the assembly relationship between the support device and the door body.

[0136] Combination Figure 1 , Figures 10 to 12As shown, a door assembly 15 is provided at the front end of the inner liner assembly. The door assembly 15 is fixedly connected to the support device 13 and seals one side of the inner liner. Since the door 152 has a planar structure, it is not easy to fix it to the support device perpendicular to the door. Therefore, the door assembly 15 also includes a door connector 151, such as... Figure 11 As shown, the door connector 151 is fixedly connected to the door body 152 and the support device respectively; the door connector includes at least a first connecting part 1511 connected to the support device and a second connecting part 1512 connected to the door body. The first connecting part 1511 and the second connecting part 1512 are two vertically arranged plate-like structures, and are generally angular. One plate is opposite to the door body, and the other plate is used for fixed connection with the support device, making the assembly between the support device and the door body more stable.

[0137] like Figure 11 As shown, the door connector 151 has a second connecting part 1521 that is fixedly connected to the door body. The door body 152 has a door mounting part 1521 corresponding to the door connector 151 on the side facing the door connector 151. The second connecting part 1512 is attached to the door mounting part 1521 and has mounting holes respectively. The specific fixing method can be that the second connecting part 1512 and the door mounting part have screw holes respectively, and the door connector 151 and the door body 152 are fixedly connected by screws.

[0138] like Figure 11 As shown, for the sake of a stable connection, the second connecting part 1512 has at least two screw holes arranged longitudinally, and the door body 152 has screw holes of the same number and corresponding position as the first connecting part. Three sets of screw holes are provided longitudinally to make the fit between the door body and the door body connector more secure.

[0139] The first connecting part 1511 is fixedly connected to the support device. The first connecting part 1511 includes at least a fixing structure that is fixedly connected to the support device, and the support device has a corresponding fixing fit structure.

[0140] Specifically, such as Figure 12 As shown, the support device is fixedly provided with a first longitudinal plate 1331 and a second longitudinal plate perpendicular to the door body 152 in the direction of the door body. The first connecting part 1511 is perpendicular to the door body 152 and is inserted between the first longitudinal plate 1331 and the second longitudinal plate.

[0141] After being inserted a certain distance, the edge of the first connecting part 1511 of the door connector abuts against the edge of the first longitudinal plate 1331. The first connecting part 1511 of the door connector 151 is located close to the inner wall of the second longitudinal plate. There is a certain distance between the first longitudinal plate 1331 and the second longitudinal plate to ensure that it can be installed in conjunction with the angular door connector.

[0142] In order to ensure that the support device is fixedly installed with the door body connector, mounting holes are provided at corresponding positions of the first longitudinal plate, the second longitudinal plate, and the first connecting part, and the support device is fixedly connected with the door body connector by fasteners.

[0143] like Figure 12 As shown, the fastener is a buckle with one square end and one round end. As shown in the figure, the first vertical plate 1331 is provided with a square first buckle mounting hole 13311, the second vertical plate is provided with a round second buckle mounting hole 13321, and the first connecting part is provided with a round third buckle mounting hole 15112. The fastener is inserted into the first buckle mounting hole first from the round end, then passes through the third buckle mounting hole 15112 of the door body connector, and finally inserts into the second buckle mounting hole 13321, so that the door body connector and the support device are connected.

[0144] For ease of assembly, the door assembly 15 can be positioned first using a positioning structure and then fixedly connected using a fixing structure. The first connecting part is limited to the support device, restricting the relative movement of the door connecting part and the support device in the front-back / left-right directions. The first connecting part includes a limiting structure that is limited to the support device, and the support device has a corresponding limiting fit structure.

[0145] Specifically, such as Figure 12 As shown, the top edge of the first connecting part 1511 is provided with a plug-in part 15111, and a horizontal plate-like structure is provided between the first vertical plate 1331 and the second vertical plate. The plate-like structure is provided with a positioning port 1333 that matches the shape of the plug-in part. The plug-in part 15111 is inserted into the positioning port 1333 from bottom to top. After the plug-in structure is positioned, the third snap-fit ​​mounting hole 15112 can be aligned with the positions of the first snap-fit ​​mounting hole 13311 and the second snap-fit ​​mounting hole 13321, which is more conducive to the assembly efficiency.

[0146] The bottom of the support device is provided with a slide rail mounting groove that extends vertically to the door body direction. The second connecting part of the door body connector 151 blocks one end of the slide rail mounting groove, which can further prevent the slide rail from detaching from the inner liner assembly.

[0147] The support device is the core component of the inner liner assembly. The door body and the support device are more reliably fixedly connected. The support device is equipped with a connection structure facing the door body for easy installation. A door body connector is provided between the door body and the support device. The door body connector has a positioning and fixing connection structure, which makes the door body assembly more firmly assembled on the inner liner assembly and easy to disassemble and assemble. When the door body needs to be replaced, it can be replaced by removing the fasteners.

[0148] Example 4

[0149] This embodiment mainly describes in detail the specific structure of the outer side plate assembly structure that cooperates with the support device and the outer side plate, as well as its assembly relationship with the outer side plate.

[0150] The following is a detailed description of the assembly structure of the outer side plate of the support device.

[0151] Combination Figure 5 As shown, the support device provided in this embodiment includes a support body with an extended length. The support body has an assembly structure, which includes an outer panel assembly structure. The support body includes a first support frame, which includes a first support plate 1325 with a certain extended length, a second support plate 1326 parallel to the first support plate, and a top plate 1327 connected to the upper surfaces of the first and second support plates. The outer panel assembly structure is disposed on the second support plate 1326. The outer panel assembly structure includes a plug-in plate 1342 formed by extending downward from the lower edge of the second support plate 1326. The outer panel assembly structure disposed on the support device can effectively solve the assembly connection problem between the base and / or the inner liner and / or the door body and the outer panel.

[0152] In another option, such as Figure 14 As shown, the outer side plate positioning part 1342 is a horizontal positioning platform formed by the bottom edge of the support body extending outward horizontally, and a positioning structure for assembly positioning is provided on the horizontal positioning platform.

[0153] The positioning structure is a positioning protrusion on the positioning platform; or, the positioning structure is a positioning groove on the positioning platform; or, the positioning structure is a positioning hole on the positioning platform, which is fixed by screws or buckles.

[0154] like Figure 5 and Figure 13 As shown, the outer side panel assembly structure further includes side panel mounting holes 1341 formed on the second support plate 1326 and / or the plug-in plate 1342, the side panel mounting holes 1341 corresponding to and engaging with the fourth snap-fit ​​mounting holes 162 on the outer side panel 16. The length / width of the second support plate 1326 is not greater than the corresponding length / width of the outer side panel 16, and the side of the second support plate 1326 near the outer side panel 16 has a smooth mating surface, so that the outer wall of the second support plate 1326 fits tightly against the inner wall of the outer side panel, facilitating a fixed connection.

[0155] Preferably, in this embodiment, the side panel mounting hole 1341 corresponds to the fourth buckle mounting hole 162 and the first buckle mounting hole 13311, so as to facilitate the overall installation. The outer side panel, door assembly and support device can be connected and fixed together by a buckle, which reduces the number of parts, makes assembly simple and facilitates disassembly and replacement.

[0156] The following is a detailed description of the structure of the outer side plate:

[0157] like Figure 13-14 As shown, the outer side plate 16 is provided with a first connecting structure that connects to the support device. The outer side plate body is a plate-like structure disposed on the outside of the inner liner 11 side plate. The plate-like structure covers the inner liner 11 side plate to achieve the effect of not exposing the inner liner 11 side plate for aesthetic purposes. Figure 13 The outermost panel 16 is the outermost panel body. The outermost panel 16 is provided with a first connecting structure and is fixedly connected to the support device, so that the outermost panel 16 is firmly connected to the support device, preventing the outermost panel 16 from falling off due to loose connection, and at the same time avoiding the vibration of the outermost panel 16 during the operation of the dishwasher and thus improving the user experience.

[0158] Specifically, the first connecting structure includes a connecting arm 161 formed by bending the bottom end of the outer side plate 16, and the connecting arm 161 is provided with a connecting portion. This provides a connecting surface on the outer side plate 16 for connection with the support device. Simultaneously, the connecting arm 161 also serves as a positioning element during the connection and assembly of the support device and the outer side plate 16, accelerating the connection and assembly efficiency between the outer side plate 16 and the support device. The connecting arm extends integrally or is spaced apart along the length direction of the bottom end of the plate-like structure.

[0159] The connecting arm 161 is formed by bending the bottom end of the outer side plate 16 toward the side opposite to the outer side plate 16. The bending of the bottom end of the outer side plate 16 toward the side opposite to the outer side plate 16 to form the connecting arm 161 ensures that the connection position between the outer side plate 16 and the support device is not exposed, thus not affecting the aesthetics of the dishwasher inner tub.

[0160] Alternatively, the connecting arm 161 can be formed by bending the bottom end of the outer panel 16 away from the inner liner. The connecting arm 161 is located on the side of the outer panel 16 away from the inner liner, rather than between the inner liner and the outer panel 16. This increases the assembly connection space, making the assembly connection between the outer panel 16 and the support device more convenient and accelerating assembly efficiency.

[0161] The outer side plate 16 is fixedly connected to the support device via a snap-fit ​​structure, wherein the connecting part is a snap-fit ​​boss or snap-fit ​​hole provided on the connecting arm 161. The outer side plate 16 and the support device are fixedly connected via a snap-fit ​​structure, eliminating the need for additional connecting parts, saving costs, and speeding up the connection and assembly efficiency.

[0162] Specifically, the snap-fit ​​protrusions or snap-fit ​​holes are integrally extended on the connecting arm 161 along the pull-out direction of the dishwasher; or the snap-fit ​​protrusions or snap-fit ​​holes are spaced apart on the connecting arm 161 along the pull-out direction of the dishwasher.

[0163] Alternatively, the outer side plate 16 can be fixedly connected to the support device via a connector, wherein the connection is a connecting hole on the connecting arm 161 for the connector to pass through. The connector is a screw, which passes through the connecting hole on the connecting arm 161 to securely connect the support device and the outer side plate 16. Screws are standard parts and easy to procure, eliminating the need for redesigning a new connection structure; only a connecting hole needs to be made on the connecting arm 161, and the connection process is mature and reliable.

[0164] The connecting arm 161 is also provided with a positioning part; specifically, the positioning part is a positioning boss 1651 or a positioning notch provided on the connecting arm 161. Preferably, the positioning boss 1651 or the positioning notch is provided at the end of the connecting arm 161. The provision of the positioning part is beneficial to the assembly and positioning connection between the support device and the outer side plate 16 body, and speeds up the assembly and connection efficiency.

[0165] As another embodiment of this invention, as shown in Figure 13, a limiting groove is provided on the lower part of the outer side plate 16 body, and the lower part of the outer side plate 16 is connected to the support device through the limiting groove.

[0166] The limiting groove extends along the dishwasher's pull-out direction on the outer side plate 16, and a first limiting part is provided on the groove wall near the groove opening. The limiting groove extends along the dishwasher's pull-out direction on the outer side plate 16, and the first limiting part is provided on the groove wall near the groove opening, allowing the connecting part of the support device to slide into the limiting groove from one end. The first limiting part on the groove wall at the groove opening restricts the connecting part of the support device from moving out of the upper groove opening of the limiting groove.

[0167] Specifically, the first limiting part is a limiting boss extending along the length direction of the limiting groove. Preferably, the limiting boss extends integrally or is spaced apart along the length direction of the limiting groove. The limiting boss is integrally injection molded onto the groove wall of the limiting groove. Integral extension of the limiting boss along the length direction of the limiting groove facilitates its molding, while spaced-apart extension saves material and makes the assembly of the limiting groove and the support device easier.

[0168] The limiting groove is further provided with a second limiting part, which is a limiting wall located at one end of the limiting groove along its length. The second limiting part prevents the connecting part of the support device from moving out of one end of the limiting groove along its length.

[0169] Specifically, the limiting wall and the limiting groove are integrally formed. That is, one end of the limiting groove along its length has an opening for the connection part of the support device to be installed, while the other end is closed.

[0170] A connecting part is provided on the limiting groove or the outer side plate 16. The connecting part allows the lower part of the outer side plate 16 to be fixedly assembled with the support device within the limiting groove.

[0171] The connecting part is a snap-fit ​​post or snap-fit ​​hole located at the end of the limiting groove away from the limiting wall. The connecting part of the support device slides into the limiting groove until it abuts against the limiting wall. The snap-fit ​​post or snap-fit ​​hole located at the end of the limiting groove away from the limiting wall is snapped and fixed in position with the connecting part of the support device, so that the support device is securely connected to the outer side plate 16.

[0172] Alternatively, the limiting groove extends along the dishwasher's pull-out direction on the outer side plate 16, and a connecting part is provided within the limiting groove. The connecting part securely fixes the connecting part of the support device into the limiting groove, ensuring a stable connection between the lower part of the outer side plate 16 and the support device, preventing the outer side plate 16 from falling off due to insecure installation.

[0173] Specifically, the outer side plate 16 is fixedly connected to the support device via a snap-fit ​​structure, wherein the connecting part is a snap-fit ​​boss or snap-fit ​​hole provided on the groove wall of the limiting groove. The outer side plate 16 and the support device are fixedly connected via a snap-fit ​​structure, eliminating the need for additional connecting parts, saving costs, and speeding up the connection and assembly efficiency.

[0174] Furthermore, the snap-fit ​​boss or snap-fit ​​hole extends integrally along the pull-out direction of the dishwasher on the wall of the limiting groove; or the snap-fit ​​boss or snap-fit ​​hole is spaced apart on the connecting arm along the pull-out direction of the dishwasher. The snap-fit ​​boss is integrally injection-molded onto the wall of the limiting groove, or the snap-fit ​​hole is integrally formed on the wall of the limiting groove. This makes the molding and manufacturing of the snap-fit ​​boss or snap-fit ​​hole easier, while the spaced arrangement of the snap-fit ​​boss or snap-fit ​​hole along the length of the limiting groove saves on the manufacturing material of the snap-fit ​​boss, and also makes the assembly of the limiting groove and the support device easier.

[0175] In another embodiment of this invention, the outer side plate 16 is fixedly connected to the support device via a connector. The connector is a connecting hole provided on the wall of the limiting groove for the connector to pass through. The connector is a screw, which passes through the connecting hole on the wall of the limiting groove to securely connect the support device and the outer side plate 16. Screws are standard parts and easy to procure, eliminating the need for redesigning a new connection structure; only a connecting hole needs to be made in the wall of the limiting groove, making the connection process mature and reliable.

[0176] The limiting groove is integrally bent at the lower end of the outer side plate 16; the connection strength between the limiting groove and the outer side plate 16 is relatively large, making the connection between the outer side plate 16 and the limiting groove more secure.

[0177] Specifically, the limiting groove is formed by bending the lower end of the outer side plate 16 towards the opposite side of the outer side plate 16 to form a U-shaped groove 161. This ensures that the connection position between the outer side plate 16 and the support device is not exposed, thus not affecting the aesthetics of the dishwasher's inner tub.

[0178] In another embodiment of this invention, the limiting groove is formed by bending the bottom end of the outer side plate 16 away from the inner liner to form a U-shaped groove 161. The limiting groove is located on the side of the outer side plate 16 away from the inner liner, rather than between the inner liner and the outer side plate 16. This increases the assembly connection space, making the assembly connection between the outer side plate 16 and the support device more convenient and accelerating the assembly efficiency.

[0179] Alternatively, the connecting part can be a connecting hole provided on the groove wall of the outer side plate 16 or the limiting groove for a connecting member to pass through. The connecting member can be a standard part such as a bolt or screw, or the connecting member can be a snap fastener, and the connecting hole is a snap fastener mounting hole opened on the groove wall of the outer side plate 16 or the limiting groove. The snap fastener passes through the snap fastener mounting hole to fix the outer side plate 16 to the support device. The snap fastener mounting hole is the fourth snap fastener mounting hole 162.

[0180] Furthermore, a slide rail is provided along the pull-out direction of the dishwasher. A limiting structure is provided at one end of the slide rail near the door of the dishwasher, and an avoidance notch 164 is provided at one end of the outer side plate 16 near the limiting structure to avoid the limiting structure. The avoidance notch 164 not only serves to avoid the limiting structure at the end of the slide rail, but also serves to cooperate with the limiting structure at the end of the slide rail for limiting.

[0181] like Figure 15 As shown, the upper end of the outer side plate 16 is provided with a second connecting structure, which is connected to the sealing frame 14 located at the opening of the inner liner. That is, the upper end of the outer side plate 16 is connected to the opening of the inner liner through the sealing frame located at the opening of the inner liner. By providing a first connecting structure at the lower part of the outer side plate 16 for fixed connection with the support device, and providing a second connecting structure at the upper part of the outer side plate 16 for fixed connection with the sealing frame 14 located at the top opening of the inner liner, the outer side plate 16 is further stably set on the outside of the inner liner, so that the outer side plate 16 will not generate vibration noise during the operation of the dishwasher, and will not cause the unfixed end to shake and generate noise because only one end is fixed and the other end is not fixed.

[0182] Specifically, the upper part of the outer side plate 16 is fixedly connected to the sealing frame 14 by an insertion joint. The second connection structure includes an insertion part and a positioning part, with the positioning part located at the bottom end of the insertion part. The upper part of the outer side plate 16 is connected to the sealing frame by an insertion joint, eliminating the need for additional connectors and improving assembly efficiency. The positioning part serves to position the components during assembly, allowing installers to quickly determine if the outer side plate 16 is properly inserted into the sealing frame 14, thus reducing installation time.

[0183] Furthermore, the insertion portion and / or positioning portion are either integrally extended or spaced apart on the upper part of the outer side plate 16 along the dishwasher's pull-out direction. The integral extension of the insertion portion and / or positioning portion on the upper part of the outer side plate 16 along the dishwasher's pull-out direction facilitates processing and forming. The spaced arrangement of the insertion portion and / or positioning portion on the upper part of the outer side plate 16 along the dishwasher's pull-out direction reduces the difficulty of insertion and connection, and makes assembly between the upper part of the outer side plate 16 and the sealing frame 14 easier.

[0184] The upper end of the outer side panel 16 is bent outwards towards the inner liner to form a first bend. The free end of the first bend is bent horizontally inwards towards the inner liner to form a horizontal bend. The free end of the horizontal bend is bent vertically upwards to form a vertical bend. The horizontal bend serves as a positioning part, and the vertical bend serves as a connecting part. Preferably, the first bend is an arc-shaped bend. The connecting part and the positioning part are integrally bent from the upper part of the side wall body, increasing the connection strength between the connecting part and / or the positioning part and the outer side panel 16. The first bend brings the outer side panel 16 closer to the inner liner, making the outer side panel 16 more closely fitted to the inner liner, reducing the space occupied by the outer side panel 16, and increasing the internal space of the inner liner.

[0185] In one embodiment of this invention, the drawer dishwasher is equipped with a photoelectric detection device for detecting whether the dishwasher door is open or closed. The outer panel 16 is provided with a light path avoidance hole for the light path emitted by or reflected from the photoelectric detection device. The photoelectric detection device allows the user to clearly understand the degree of closure of the dishwasher door, preventing situations where the user forgets to close the door or the door is not fully closed. Furthermore, it prevents water from splashing out of the door during operation, thus avoiding any impact on the user experience. Preferably, the light path avoidance hole includes a first light path avoidance hole 1631 and a second light path avoidance hole 1632.

[0186] The following is a detailed description of the assembly relationship between the support device and the outer side plate.

[0187] Combination Figure 1 and Figure 2The outer side panels are disposed on opposite sides of the inner liner, and the support device is connected to the outer side panels. Since the support device 13 includes a first support device and a second support device, the corresponding outer side panel 16 also includes a first outer side panel disposed on one side of the first support device and a second outer side panel disposed on one side of the second support device, and the two outer side panels are symmetrically arranged.

[0188] The outer side panel needs to be fixed on the side of the support away from the inner liner, serving a decorative purpose. For example... Figure 5 As shown, the support device includes at least an outer side plate positioning part 1342 that is positioned and connected to the outer side plate, and the outer side plate has an outer side plate positioning mating part that is positioned and connected to the support device.

[0189] like Figure 5 As shown, the outer side plate positioning part 1342 includes a vertical bottom edge extending downward from the bottom edge of the support device, and the positioning mating part of the outer side plate includes a positioning groove at least at the bottom, such as... Figure 12 As shown, the positioning groove is a U-shaped groove 161. The U-shaped groove 161 is formed by bending the bottom edge of the outer side plate body towards the support device to form a groove structure. The width of the U-shaped groove matches the thickness of the outer side plate positioning part 1342 so that the outer side plate positioning part of the support device can be inserted into the positioning groove.

[0190] Another implementation method is, as follows: Figure 14 As shown, the outer side plate positioning part 1342 includes a positioning platform provided at the bottom edge of the support device and extending toward the outer side plate. The positioning and fitting structure of the outer side plate includes at least a folded edge provided at the bottom and bent toward the support device, and the folded edge is provided above the positioning platform.

[0191] The support device needs to be fixedly connected after the outer side plate is positioned to ensure that the outer side plate will not fall off. The support device also includes an outer side plate connecting part 1341 that is fixedly connected to the outer side plate, and the outer side plate 16 has an outer side plate connecting mating part that is fixedly connected to the support device 13.

[0192] like Figure 1 As shown, the inner liner assembly also includes a sealing frame 14 at the top of the inner liner. The sealing frame 14 can also limit the outer panel to a certain extent. On one side of the sealing frame, there is a blocking edge 141 facing the outer panel, which can limit the outer panel. The bottom of the outer panel is positioned with the support device, and the top cooperates with the sealing frame.

[0193] like Figure 13As shown, the outer side panel 16 and the support device 13 each have corresponding mounting holes. After the mounting holes are aligned, fasteners are inserted to secure the connection. This structure can be installed together with the door assembly structure. In this case, the outer side panel is provided with a fourth snap-fit ​​mounting hole 162 corresponding to the first snap-fit ​​mounting hole 13311. The outer side panel, support device, and door can be fixedly connected together by snap-fit, reducing the number of fasteners and facilitating assembly. Alternatively, the fasteners can be screws, and the mounting holes can be screw holes. At least one screw hole can be provided at the corresponding position of the support device and the outer side panel, and multiple screw holes can also be provided to facilitate the fixation of the structure.

[0194] Because the support device has many mounting structures, some need to be covered to prevent unsightly exposure, while others cannot be covered and need to be avoided. The outer side plate has a avoidance structure. For example... Figure 13 As shown, the support device is provided with a light guide column mounting position, and the outer side plate has a clearance hole for avoiding the light path; the outer side plate includes a first clearance hole 1631 and a second clearance hole 1632, the first clearance hole 1631 avoids the emitted light path, and the second clearance hole avoids the reflected light path 1632. A light reflector corresponding to the light path is provided on the inner wall of the box, and the position of the door is detected by reflection.

[0195] In addition, due to the decorative function of the outer side panel, as much of the structure as possible should be covered to ensure aesthetics. The bottom of the support device is provided with a slide rail connection part and is fixedly connected to the slide rail. The outer side panel covers the slide rail connection part and part of the slide rail from the side.

[0196] Because one end of the slide rail has a limiting protrusion, the slide rail connecting part has a limiting notch that abuts against the limiting protrusion, and the outer side plate has an avoidance notch that matches the shape of the limiting notch. If no avoidance is made, the limiting notch will not reliably limit the slide rail. The plate at the limiting notch is too thin to abut against the limiting protrusion.

[0197] The outer side plate is generally square, and its length / width is not less than the length / width of the supporting device, so as to cover the structure of the supporting device. The supporting device has a smooth mating surface on the side facing the outer side plate, and the outer side plate fits tightly against the mating surface and completely covers the mating surface.

[0198] The outer side panel can slide with the support device during assembly through positioning grooves and other positioning structures. The assembly method is simple and can ensure the accuracy of positioning. The outer side panel is fixed to the support device together with the door body through the connection structure between the door body and the support device, which reduces the number of installation parts, saves costs, and reduces assembly steps.

[0199] Example 5

[0200] This embodiment mainly provides a detailed description of the specific structure of the light guide post assembly structure in which the support device and the light guide post cooperate.

[0201] An LED light is installed on the circuit board inside the dishwasher. The light emitted by the LED light is transmitted through a light guide column. The assembly structure of the support device provided in this embodiment also includes a light guide column assembly structure set on the support body for installing the light guide column to realize the detection of the door position.

[0202] Specifically, the support body includes a first support frame and a second support frame fixedly connected to one end of the first support frame. The second support frame includes a vertical plate vertically arranged on the first support frame. The first light guide post mounting position and the second light guide post mounting position are light guide post mounting holes arranged longitudinally on the vertical plate.

[0203] Combination Figure 10 , Figure 12 and Figure 16 As shown, the light guide post mounting holes include a first mounting hole 13312 and a second mounting hole 13313 that are arranged opposite to each other and horizontally at a certain distance. The two mounting holes are arranged at an interval to achieve a more stable installation and fixation of the light guide post.

[0204] Furthermore, such as Figure 12 As shown, the longitudinal plate includes a first longitudinal plate 1331 and a second longitudinal plate as in Embodiment 3. The first longitudinal plate and the second longitudinal plate are arranged in parallel and spaced apart. The first mounting hole 13312 is provided on the first longitudinal plate 1331, and the second mounting hole 13313 is provided on the second longitudinal plate corresponding to the first mounting hole 13312.

[0205] Preferably, combined with Figure 10 and Figure 16 As shown, a third longitudinal plate 1361 is provided above the support column and is perpendicularly connected to the first longitudinal plate 1331. The second longitudinal plate includes an upper longitudinal plate 1362 provided on the upper part of the third longitudinal plate, and the second mounting hole 13313 is provided on the upper longitudinal plate 1362.

[0206] Specifically, such as Figure 16 As shown, the first mounting hole 13312 is a circular hole opened on the first longitudinal plate 1331, and the second mounting hole 13313 is an arc-shaped notch opened on the upper longitudinal plate 1362.

[0207] Preferred, such as Figure 10 As shown, the light guide post assembly structure also includes a light guide post support plate for supporting the light guide post, preventing the light guide post from detaching from the light guide post mounting position and falling out of the gap between the first longitudinal plate and the second longitudinal plate. The light guide post support plate includes a first light guide post support plate 1363 located below the first light guide post mounting position and a second light guide post support plate 1364 located below the second light guide post mounting position.

[0208] The first light guide post support plate 1363 and the second light guide post support plate 1364 are connected between the first vertical plate 1331 and the second vertical plate, which serve to support the light guide post and enhance the stability of the first vertical plate and the second vertical plate.

[0209] The system utilizes light guide post mounting positions on the supporting body. A first light guide post mounting position is used to mount a first light guide post for light to enter, and a second light guide post mounting position is used to mount a second light guide post for light to exit. The light path exits from the first light guide post, and a corresponding reflective element is installed on the housing. The light path is refracted back to the second light guide post by the reflective element, thus detecting whether the door is fully closed. If the light path is detected to be refracted back to the second light guide post, then it can be determined that the door is fully closed.

[0210] Example 6

[0211] This embodiment will describe in detail the specific structure of the inner liner in this invention and how the inner liner is made.

[0212] like Figure 18-19 As shown, the inner liner 11 includes a bottom plate and a side plate assembly disposed on the bottom plate and surrounding the bottom plate to form the side wall of the inner liner. The side plate assembly is configured as an outward convex structure protruding from the inside of the inner liner 11 to the outside.

[0213] In the above scheme, the inner liner 11 is designed to bulge outward from the inside of the inner liner, which increases the capacity of the inner liner 11 and realizes the expansion of the inner liner.

[0214] Preferably, the inner liner 11 is slidably disposed within the dishwasher cabinet, and the side panel assembly includes two side panels extending along the sliding direction of the inner liner 11, both side panels being configured as outwardly convex structures protruding away from the opposite side panel.

[0215] In the above scheme, both side plates are designed to be convex structures, thereby increasing the size of the inner liner and the internal space of the inner liner in a direction perpendicular to the sliding direction of the inner liner.

[0216] Preferably, the inner liner includes a front plate and a rear plate that are respectively connected to the two ends of the two side plates. The middle part of the side plates protrudes outward, and the two sides of the side plates bend and extend towards the front plate and the rear plate respectively along the sliding direction of the inner liner.

[0217] In the above scheme, the side panel configuration is obtained by stamping a large area in the middle of the side panel, forming a structure that protrudes in the middle and recedes around the perimeter, thereby increasing the internal space of the inner liner. Specifically, an outwardly convex molding 114 is stamped on the side panel in the opposite direction to the opposite side panel, forming a shell structure in which the bottom wall convexes outward and the peripheral wall extends towards the opposite side panel. In this method, stamping a large area in the middle of the side panel increases the internal space of the inner liner.

[0218] Alternatively, the side panel can be designed by bending and recessing the lower edge of the side panel into the inner liner, forming a structure with a protruding upper part and a recessed lower part. The recessed lower part is used to avoid slide rails or support devices, while the protruding upper part increases the internal space of the inner liner.

[0219] Preferably, the side panels have first extension surfaces on both sides along the sliding direction of the inner liner, bent towards the front and rear panels respectively to connect them. The middle part of the side panel is a planar structure, and the two sides of the planar structure are smoothly connected to the corresponding first extension surfaces via first arc surfaces. The middle part of the side panel is stamped into a convex plane, and the planar arc surface transitions to the side edge of the side panel. This reduces the stamping strength of the side panel, resulting in a high-strength, high-quality inner liner. The smooth transition of the inner liner also results in a good overall gloss and attractive appearance. Through the design on the first extension surface, the joint position is shifted from the corner between the side panel and the front and rear panels to the plane where the front or rear panel is located, simplifying the connection between the side panel and the front and rear panels.

[0220] The middle part of the side panel is flat, and the flat surface transitions smoothly to the edge of the side panel on both sides along the sliding direction of the inner liner through a first arc. The curved surface of the middle part of the side panel transitions to the side edge of the side panel, which reduces the stamping strength of the side panel, resulting in a strong and high-quality inner liner. The smooth transition of the inner liner also results in a good overall gloss and beautiful appearance.

[0221] In this embodiment, the inner liner is a drawer structure, comprising a front panel and a rear panel respectively connecting the two ends of two side panels. Each side panel has a first extension surface that bends and extends towards the front and rear panels, respectively. The first extension surface connects to the corresponding front / rear panel, and the bottom wall of the inner liner transitions to the first extension surface via a smooth first arc surface. This design on the first extension surface shifts the seam location from the corner between the side panel and the front / rear panels to the plane where the front or rear panel is located, simplifying the connection between the side panel and the front / rear panels.

[0222] See Figure 19 As shown, in one embodiment, after the side plate is stamped and formed by 114, a recessed surface 115 is formed at the bottom of the side plate that is recessed into the inner liner. The recessed surface 115 is used to avoid the slide rails or support devices of the dishwasher.

[0223] In the above solution, the inner liner is formed with a recessed surface to avoid the dishwasher slide rails or support devices, thereby making full use of the space inside the dishwasher shell and facilitating the expansion of the inner liner.

[0224] Preferably, the recessed surface 115 includes a recessed surface that gradually recedes into the inner liner from top to bottom and a vertical surface extending downward from the end of the recessed surface. The cross-sectional profile of the recessed surface, longitudinally cut by the vertical surface perpendicular to its side plate, includes, from top to bottom, a first curve 1153 with its center of curvature inside the inner liner and a second curve 1154 with its center of curvature outside the inner liner. The first curve and the second curve have a smooth transition. Preferably, the length of the first curve is equal to the length of the second curve. More preferably, the curvature of the first curve is equal to the curvature of the second curve. Through this structural design, the edge of the outwardly convex pressing type, or the two bends of the recessed surface 115, has the same tensile strength, the plate is stretched uniformly, and the thickness is uniform, thereby preventing local overstretching from affecting the quality of the inner liner.

[0225] See Figure 18 As shown, in another structure, the recessed surface is formed by directly stamping the bottom of the side plate into the inner liner. The recessed surface includes a horizontally bent surface 1151 formed by bending the bottom wall of the side plate from top to bottom into the inner liner, and a vertically bent surface 1152 formed by bending the end of the horizontally bent surface 1151 downwards. The horizontally bent surface and the vertically bent surface are connected and transitioned by a smooth arc surface. This structure is similar to... Figure 19 The structures are different. Figure 19 The concave surface is indirectly formed by the convex stamping die. Because the die is large, it cannot withstand high stamping strength, therefore it lacks a horizontal bending surface. Figure 16 Because the recessed surface is directly stamped, the stamping area is small, allowing for the stamping of recessed surfaces with both horizontal and vertical bending surfaces. The support device is equipped with a slide rail mounting section, which is a slide rail mounting groove extending along the length of the slide rail. The recessed surface 115 is used to avoid the slide rail mounting groove. The slide rail mounting groove includes a top plate and two side plates located on either side of the top plate. The top plate is parallel to the horizontal bending surface, and the side plates are parallel to the vertical bending surface.

[0226] Furthermore, the upper end of the slide rail mounting groove side plate near the inner liner is provided with a clearance step. The clearance step extends along the length of the slide rail mounting groove and is a recessed step formed by the upper end of the slide rail mounting groove side plate indenting away from the inner liner. Specifically, the recessed step includes a first bend formed by the upper end of the slide rail mounting groove side plate bending away from the inner liner, and the free end of the first bend bends upward to form a second bend; the free end of the second bend is connected to the top plate of the slide rail mounting groove.

[0227] Preferably, the bottom edge of the side panel has a second extending surface that bends and extends towards the bottom plate, and the recessed surface smoothly transitions to the second extending surface. The second extending surface is connected to the bottom plate of the inner liner.

[0228] Furthermore, the front and / or rear panels of the inner liner are similar to the two side panels, featuring an outward convex structure that expands the inner liner's capacity. Their structure can be similar to the two side panels mentioned above, with the recessed surface at the bottom of the rear panel avoiding the rear water passage. Further details will not be elaborated upon here.

[0229] As one embodiment of this example, such as Figure 17 As shown, in this embodiment, the inner liner 11 is composed of three splicing components, including a first splicing component, a second splicing component, and a third splicing component. The second splicing component and the third splicing component are located on both sides of the first splicing component and are parallel to the pull-out direction of the dishwasher. The splicing position of the second splicing component / third splicing component and the first splicing component is located on a plane.

[0230] The first splicing component includes a bottom plate 110 of the inner liner and a front plate 112 and a rear plate 113 connected to the bottom plate 110 and perpendicular to the dishwasher's pull-out direction.

[0231] The second / third splicing component includes a side panel 111 parallel to the dishwasher's pull-out direction. The second / third splicing component also includes an extension that is connected to the side panel 111 and bends towards the opposite side panel. The extension is connected to the first splicing component and includes a rounded corner structure between the inner wall surfaces. The extension is provided so that the splicing position of the second / third splicing component and the first splicing component is located on a plane.

[0232] The second splicing component / third splicing component is integrally formed by stamping. The extension includes a first extension surface 1111 located on the bottom surface of the side plate 111 and a second extension surface 1112 located on the side surface of the side plate 111. After forming the rounded corner structure between the inner wall surfaces, the extension continues to extend straight towards the opposite side plate. The first extension surface 1111 is connected to the bottom plate 110 in the first splicing component, and the second extension surface 1112 is connected to the front plate 112 / rear plate 113 in the first splicing component.

[0233] The side plate 111 of the second splicing component / third splicing component includes a recessed surface 115, which is a receiving part recessed towards the center of the inner tank. The receiving part can be used to avoid slide rails or support devices, so as to facilitate the inner tank to be pushed into or pulled out of the dishwasher body, and to take out and put away the tableware in the dishwasher.

[0234] Same as the previous implementation method, such as Figure 18The recessed surface 115 includes a horizontally bent surface 1151 formed by bending from top to bottom into the inner liner, and a vertically bent surface 1152 formed by bending downward at the end of the horizontally bent surface 1151. The horizontally bent surface 1151 and the vertically bent surface 1152 are connected and transitioned by a smooth arc surface.

[0235] The slide rail mounting groove includes a slide rail mounting groove top plate and two slide rail mounting groove side plates located on both sides of the slide rail mounting groove top plate. The slide rail mounting groove top plate is arranged parallel to the horizontal bending surface 1151, and the slide rail mounting groove side plates are arranged parallel to the vertical bending surface 1152.

[0236] Preferably, in this embodiment, the bottom of the vertical bending surface 1152 is provided with a first extension surface 1111 that bends and extends toward the base plate 110, and the first extension surface 1111 is connected to the corresponding side of the base plate 110.

[0237] In the above scheme, the bottom edge of the horizontal bending surface 1151 bends towards the bottom to form the first extension surface 1111. The first extension surface 1111 is preferably in the same plane as the base plate 110. In this way, the splicing position of the lower edge of the base plate 110 and the side plate 111 is on the plane, not at the corner, which facilitates the splicing and alignment of each splicing part, and moves the welding position to the plane, reducing the welding difficulty.

[0238] Preferably, the side plate 111 is provided with a second extension surface 1112 on both sides, which bends and extends toward the front plate 112 and the rear plate 113 respectively, and the second extension surface 1112 is connected to the corresponding front plate 112 or rear plate 113.

[0239] In the above scheme, the two sides of the side plate 111 are bent to form the second extension surface 1112 to the front plate 112 and the rear plate 113. The side of the second extension surface 1112 that is spliced ​​with the front plate 112 or the rear plate 113 is in the same plane as the front plate 112 or the rear plate 113, thereby avoiding the corner and facilitating welding and fixing.

[0240] In this embodiment, the design of the second extended surface 1112 prevents splicing on the recessed surface 1115, shifts the splicing position to the plane, and simplifies the welding process.

[0241] At the splicing position, the edge of the first splicing component bends outward toward the inner liner to form a first connecting surface, and the edge of the second / third splicing component bends outward toward the inner liner body to form a second connecting surface. The first connecting surface and the second connecting surface are then welded together.

[0242] At the splicing position, the edge of the first splicing component bends outward toward the inner liner to form a first connecting surface, and the edge of the second / third splicing component bends outward toward the inner liner body to form a second connecting surface. The first connecting surface and the second connecting surface are then welded together.

[0243] At the splicing position, the second / third splicing component is connected to the first splicing component by a rolled edge. At the splicing position, the edge of the first splicing component bends outward toward the inner liner body to form a first connecting surface. The first connecting surface is U-shaped with its opening facing the center of the inner liner. At the splicing position, the edge of the second / third splicing component bends outward toward the inner liner, extends toward the opposite splicing component, and then bends upward to form a second connecting surface. The second connecting surface is U-shaped with its opening facing the opposite direction to the first connecting surface. The first and second connecting surfaces are nested together.

[0244] like Figure 20 As shown, a sealing frame 14 is also provided at the top opening of the inner liner 11, and a mounting groove for assembling the top opening of the inner liner is provided on the bottom side of the sealing frame 14 near the inner liner. A water-blocking structure 117 is provided on the side wall of the inner liner 11 to prevent water from entering the gap between the sealing frame 14 and the wall of the inner liner 11. The water-blocking structure 117 effectively prevents washing water from entering through the gap between the sealing frame 14 and the wall of the inner liner 11, thus preventing water from eroding the sealing structure, extending the service life of the sealing structure, and improving the overall user experience of the product.

[0245] To avoid friction and noise during assembly between the sealing frame 14 and the inner liner 11, and to improve the tightness of the seal, a sealing ring 142 is provided between the sealing frame 14 and the inner liner 11.

[0246] like Figure 20 As shown, the water-blocking structure 117 is a protruding structure recessed towards the center of the inner tank, and the surface of the protruding structure is arc-shaped. The groove wall of the mounting groove of the sealing frame 14 is provided with a receiving part. The water-blocking structure 117 is snapped into the receiving part. The receiving part is a groove recessed towards the center of the inner tank from the groove wall of the mounting groove. The inner surface of the groove is consistent with the outer surface shape of the water-blocking structure 117, which facilitates the installation of the sealing frame 14. While increasing the tightness of the sealing structure, it also improves the compactness of the assembly between the sealing frame 14 and the inner tank 11, and at the same time improves the safety of the dishwasher.

[0247] The water-blocking structure can also be located at the lower edge of the sealing frame. The water-blocking structure is a protruding structure that is recessed into the center of the inner liner and is located at the lower edge of the sealing frame.

[0248] The top surface of the inner liner 11 that mates with the sealing frame 14 is provided with a folding structure 116 extending outward from the inner liner. The end of the folding structure 116 forms an angle with the wall of the inner liner 11 and is inclined outward from the inner liner. The mounting groove of the sealing frame 14 and the groove wall opposite to the receiving part are provided with a through hole 143. The lower surface of the through hole 143 is longer than the upper surface and protrudes towards the inner liner 11. The end of the folding structure 116 is stuck on the lower surface of the through hole 143. When disassembling the sealing frame 14, a tool smaller than the diameter of the through hole 143 is used to enter the through hole 143 from the side away from the inner liner wall and push the end of the folding structure 116 away from the lower surface of the through hole 143. The operation is simple and provides users with a good user experience.

[0249] As a further limitation of this embodiment, the folding structure 116 located on the top surface of the inner liner 11 is either integrally extended or spaced out. The through holes 143 on the sealing frame 14 correspond one-to-one with the folding structure 116 and cooperate with each other, which is beneficial for the demolding of the sealing frame 14 and enhances the compactness of the seal.

[0250] In another embodiment, the mounting groove of the sealing frame 14 has a limiting boss on the side wall opposite to the receiving portion, and the end of the folding structure 116 is engaged with the limiting boss. Specifically, the folding structure 116 / limiting boss is either integrally extended or spaced apart. In this embodiment, the inner liner 11 includes four side plates with flat top surfaces, which are connected by rounded corner transition side plates, and the water-blocking structure 117 is located on the upper part of the side plates.

[0251] The sealing frame 14 can also be integrally injection molded onto the top of the inner liner to increase the connection strength between the inner liner and the sealing frame.

[0252] The bottom of the sealing frame 14, away from the inner liner, is also provided with a insertion groove for mounting the upper part of the outer side plate. The insertion groove is inserted and fixedly assembled with the insertion part at the upper part of the outer side plate, and is fixedly connected to the upper part of the outer side plate. The insertion groove extends as a whole along the length direction of the bottom of the sealing frame or is spaced apart, and the insertion groove and the insertion arm are arranged one-to-one.

[0253] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
