Description

Technical Field

[0001] The present invention belongs to the field of household appliances, and in particular relates to an inner tank assembly of a dishwasher and the dishwasher. Background Art

[0002] The inner tanks of existing dishwashers are mostly made of plastic injection molding. However, after a period of use, scale and other vegetable debris accumulate on the inner surface of the plastic tank, directly affecting the washing effect and cleaning efficiency. The residual scale in the plastic tank also directly affects the drying performance of the dishwasher. As a solution to this problem, stainless steel tanks are gradually being used in dishwashers. Their cleaning efficiency and drying performance are better than those of plastic tanks. However, since the stainless steel tanks need to be assembled with other parts through welding, the molding process of stainless steel tanks is complicated and not conducive to the integration of the tank components.

[0003] Household drawer-type dishwashers all contain an inner tank and an inner tank base for supporting the inner tank. Usually, when the inner tank is made of stainless steel, outer plates are also required on both sides of the stainless steel inner tank to decorate and shield the inner tank. Since the inner tank is made of stainless steel, the lower end of the inner tank is usually in a regular shape when stamped. Therefore, when connecting the stainless steel inner tank to the outer plates, it is necessary to butt-weld the relevant connecting structure at the lower end or both sides of the stainless steel inner tank to achieve the connection and fixation of the stainless steel inner tank and the outer plates. The connection is difficult. During the connection process of the outer plates of the inner tank and the base, since both the outer plates and the base are thin and easy to deform, interference is easily generated during the assembly of the outer plates and the base, which is not conducive to the positioning and installation of the outer plates and the base.

[0079] This embodiment mainly introduces in detail the specific structure of the slide rail assembly structure in which the support device cooperates with the slide rail, as well as the assembly relationship between the support device and the slide rail.

[0080] The following is a detailed description of the slide rail assembly structure of the support device:

[0081] like Figures 8-10 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 provided below the support body. Preferably, the slide rail mounting position is a slide rail mounting groove 1321 provided through the support body. The slide rail mounting groove 1321 is a concave groove with a downward opening. The shape of the inner wall of the concave groove matches the shape of the outer surface of the slide rail.

[0082] like Figure 3 andFigure 4 As shown, the support body comprises a first support frame, the first support frame comprises 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 end faces 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, and a plurality of arched rib plates 13211 are arranged in the slide rail mounting groove 1321 along the length direction of the slide rail mounting groove 1321, so as to reduce the overall weight of the support device 13 and better achieve the limiting of the slide rail.

[0083] Further, the slide rail assembly structure further comprises a first slide rail connecting portion and a second slide rail connecting portion for limiting the sliding direction and / or the up-down direction displacement of the slide rail, the first slide rail connecting portion is arranged at the front side end of the slide rail mounting groove 1321, and the second slide rail connecting portion is arranged at the rear side end of the slide rail mounting groove 1321, so as to more effectively connect and fix the slide rail at the front and rear positions.

[0084] Further, as shown in the figure, Figure 8 The first slide rail connecting portion comprises a limiting notch 1324 arranged at the front side end of the slide rail mounting groove 1321, the limiting notch 1324 is a notch arranged at the front end corner position of the first support plate 1325 / second support plate 1326, and the limiting notch 1324 is used for limiting the displacement in the sliding push-in direction of the slide rail.

[0085] Further, the first slide rail connecting portion further comprises a supporting portion 1323 arranged below the slide rail mounting groove 1321 for supporting the slide rail, the side edge of the first support plate 1325 extends horizontally to form a first vertical connecting wall, and the side edge of the first vertical connecting wall extends outwardly along the lower part to the outer wall direction of the slide rail mounting groove 1321 to form the supporting portion 1323.

[0086] Further, as shown in the figure, Figure 8As shown, the supporting portion 1323 includes a first slide rail supporting wall formed by a side edge portion of the bottom of the first vertically extending wall extending horizontally toward the outer side wall. The side end portion of the first slide rail supporting wall is bent outward to form a second slide rail supporting wall. The height of the first slide rail supporting wall and the second slide rail supporting wall is lower than the height of the first support plate 1325 to achieve the purpose of supporting the slide rail. The top surface of the second slide rail supporting wall extends toward the outer side wall to form a slide rail supporting surface to increase the supporting area. The first slide rail supporting wall described in this embodiment is the first positioning surface 1313 for positioning the corner in Example 1, and the second slide rail supporting wall is the second positioning surface 1314 for positioning the corner. The supporting portion 1323 is provided to limit the downward displacement of the slide rail in the slide rail mounting groove 1321, thereby supporting the front end of the slide rail. The supporting portion 1323 can also be formed by directly bending and extending the lower side edge portion of the first support plate 1325 inward.

[0087] Further, such as Figure 8 As shown, the second slide rail connection portion includes a hook plate 1322 arranged at the rear end of the slide rail mounting groove 1321, and 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 on the hook plate 1322, and the hook plate 1322 plays a role in connecting and fixing the slide rail, and can also play a role in limiting the downward displacement of the slide rail at the rear end in the slide rail mounting groove 1321.

[0088] 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, and one side edge of the hook plate 1322 is horizontally connected to the top wall of the slide rail mounting groove 1321, and the other adjacent 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, prevent shaking and falling off, and affect the pushing and pulling of the slide rail.

[0089] Preferably, if Figure 9 As shown, the second slide rail connection portion further includes a limiting mechanism provided at the rear end of the slide rail mounting groove 1321 for limiting the displacement of the slide rail in the sliding pushing direction. The limiting mechanism is a limiting rod 135 provided horizontally.

[0090] Preferably, the limiting mechanism includes a horizontally placed concave limiting frame, the opening of the concave limiting frame faces the slide rail mounting groove 1321, the horizontal edge in the middle of the concave limiting frame is the limiting rod 135, and the side of the concave limiting frame is integrally arranged with the hook plate 1322 to simplify the structure.

[0091] The following is a detailed description of the corresponding assembly structures and assembly relationships of the slide rail and the support device.

[0092] 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 tank 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 downward, and the lower sliding member has a groove structure with an opening facing upward. 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.

[0093] The inner container assembly is fixedly mounted to the upper slide 21 via a support device 13. Accordingly, the drawer assembly includes two symmetrically arranged sets of 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 solely on the cooperation between the first support device and the slide rails.

[0094] 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 tank is more stably arranged on the slide rail 2, the support device also has a slide rail mounting position formed by a slide rail limiting portion with a length equivalent to the slide rail 2. The slide rail mounting position is a groove-shaped slide rail mounting groove with an opening downward. The cross-sectional shape of the groove matches the shape of the outer surface 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 sunk into the slide rail mounting position, the side walls of the slide rail mounting position are tightly fitted to the upper sliding member, which can limit the relative movement of the upper sliding member 21 and the support device in the left and right directions.

[0095] like Figure 8 As shown, one end of the rear part of the upper sliding member 21 is fixedly connected to the supporting device, and a hanging ear 211 is provided on the upper surface of one end of the upper sliding member 21. The hanging ear is a structure that extends upward and then extends forward, and opens forward. The supporting 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 is hooked on the hook plate 1322 from back to front to realize the connection between the two at the rear, which can limit the displacement in the up and down directions, and limit the movement of the support plate to the rear of the slide rail.

[0096] like Figure 8 As shown, one end of the front portion of the upper sliding member 21 is fixedly connected to the supporting device, and the other end of the upper sliding member 21 is provided with a detachable and fixedly connected end cap 212, which can be inserted into the groove of the upper sliding member 21 from a horizontal direction and is fixedly connected to the upper sliding member 21. Specifically, a bayonet is provided at the top of the other end of the upper sliding member 21, and the end cap has an insertion end, and 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.

[0097] likeFigure 8 As shown, the end cap 212 and the supporting device are limited and stopped, and the end cap is provided with a limiting protrusion 2121 perpendicular to the sliding direction of the slide rail. The supporting device has a limiting notch 1324 for avoiding the limiting protrusion. The limiting protrusion 2121 and the edge of the limiting notch 1324 are stopped and stopped to limit the relative movement of the end cap 212 and the supporting device 13 forward and backward.

[0098] A supporting groove 2122 is provided at the bottom of the end cap, and a supporting portion 1323 is provided on the side of the support device facing the end cap. The supporting portion 1323 and the supporting groove 2122 stop and support the end cap 212 to limit the relative movement of the end cap and the support device.

[0099] During the assembly process, the slide rail is first hooked onto the rear end of the support device via the rear end hook. At this point, the slide rail is also placed into the slide rail mounting groove. Then, the front end of the slide rail is fixed and installed via the front end cap, completing the assembly process of the slide rail and the support device. After the slide rail and the support device are assembled, since the upper slide member can slide relative to the lower slide member, a certain limit is required to prevent the slide rail from slipping. The slide rail also includes a fixed slide rail support frame 24. A limit mechanism is provided between the slide rail support frame 24 and the support device 13 to limit the extreme position of the support device when it is pushed in.

[0100] 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 claw 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 having a claw rotatably mounted on the first part. The second part has a rotation axis, and the first part has a rotation axis groove to accommodate the rotation axis. A protrusion is provided at the rear end of the first part to limit further backward rotation of the second part. The rear end of the support device is provided with a limiting rod 135 that can be engaged with the claw and disengaged from the claw. When the limiting rod 135 is engaged with the claw and the claw swings backward to the limit angle, the support device is pushed into the limit position. When the support device moves forward, the claw first rotates a certain angle with the limiting rod. When it rotates to a certain angle, the limiting rod continues to move forward and disengages from the claw. The claw then remains in this position, waiting for the limiting rod to engage with the claw again.

[0101] The dishwasher further comprises a housing having an opening on a side. The drawer assembly is pushed and pulled from the open side. The slide rail comprises a slide rail support frame 24 which is fixedly connected to the inner wall of the housing.

[0102] The slide rail is fixedly connected to the support device through limit stops in multiple directions, which ensures the overall coordination of the slide rail and the inner tank assembly, allowing the drawer assembly to run smoothly during the pushing and pulling process to protect the tableware in the inner tank; the connection structures at the front and rear ends of the slide rail cooperate with each other, making the slide rail easier to assemble on the support device, first by hooking at the rear end to limit the up and down movement of the slide rail and the support device, and blocking the support device from moving toward the rear of the slide rail, and then supporting the supporting part through the port at the front end to limit the up and down movement of the slide rail and the support device, and blocking the support device from moving toward the front of the slide rail; the cooperation of the two limits the front and back and up and down positional movement of the slide rail and the support device, so that the slide rail and the support device can be fixedly connected on the basis of easy assembly; a limiting mechanism is also provided at the rear end of the support device, which can limit the position of the inner tank assembly when it is pushed into the interior of the box body. After reaching a certain position, the limiting mechanism limits the further movement of the inner tank assembly to protect the inner tank assembly from colliding with the rear wall of the box body.

[0103] Example 3

[0104] This embodiment mainly introduces in detail the specific structure of the door body assembly structure in which the support device cooperates with the door body, as well as the assembly relationship between the support device and the door body.

[0105] The following is a detailed description of the door assembly structure of the support device:

[0106] In this embodiment, the support device includes a support body with an extended length, the support body has an assembly structure, and the assembly structure includes a slide rail assembly structure. Figures 9-11 As shown, the support body includes the first support frame described in Example 2 and a second support frame fixedly connected to one end of the first support frame. The second support frame includes a longitudinal plate vertically disposed on one end of the first support frame, and the door assembly structure is disposed on the longitudinal plate. The door assembly structure provided on the support device also effectively solves the problem of assembling and connecting the bottom bracket and / or inner liner and / or outer panel with the door body.

[0107] Further, such as Figure 12 As shown, the longitudinal plate includes a first longitudinal plate 1331 and a second longitudinal plate arranged in parallel and spaced apart. A plate-like structure connected to the first longitudinal plate 1331 and / or the second longitudinal plate at a certain angle is provided above the first longitudinal plate 1331 and / or the second longitudinal plate, and the door body assembly structure includes a positioning port 1333 provided on the plate-like structure. The positioning port 1333 is provided to limit the movement of the door body and reduce the difficulty of assembly. 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 and 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.

[0108] Further, such as Figure 10 As shown, the longitudinal plate includes a third longitudinal plate 1361 parallel to the door body 152 and vertically connected to the first longitudinal plate 1331, the second longitudinal plate includes an upper longitudinal plate 1362 arranged on the third longitudinal plate 1361, and the plate-like structure is connected between the first longitudinal plate 1331 and the upper longitudinal plate 1362. The first longitudinal plate 1331 and the second longitudinal plate are connected by the third longitudinal plate 1361, which can effectively enhance the stability between the first longitudinal plate 1331 and the second longitudinal plate. At the same time, the upper longitudinal plate 1332 is a small section of the plate arranged on the third longitudinal plate 1361, which not only does not affect the setting of the positioning port 1333, but also can save materials and reduce material costs.

[0109] Preferably, the plate-like structure is partially connected with the third longitudinal plate 1361, and the gap forms the positioning port 1333. The gap can be used for the insertion and positioning of the plug-in portion of the door assembly 15. The plate-like structure is connected with the third longitudinal plate 1361, which can further enhance the stability of the plate-like structure and prevent the plate-like structure from deforming or falling off during the insertion of the door assembly 15, which makes it difficult for the plug-in portion of the door to be inserted into the positioning port 1333. It is used to further limit the movement of the door and the support device in the upward and / or front-back and left-right directions.

[0110] Further, such as Figure 12 As shown, the door body assembly structure includes a first assembly hole arranged on the first longitudinal plate 1331 and a second assembly hole on the second longitudinal plate, and the door body assembly 15 is fixed by fasteners. The fasteners pass through the first assembly hole on the first longitudinal plate 1331, the door body assembly 15, and the second assembly hole on the second longitudinal plate in sequence to fix the door body assembly 15 on the support device 13.

[0111] Preferably, the first assembly hole is arranged below the first longitudinal plate 1331, and the second longitudinal plate also includes a lower longitudinal plate 1332 connected to the first support frame. The second assembly hole is arranged on the lower longitudinal plate 1332 corresponding to the first assembly hole. The upper part of the door body 15 is limited and fixed by the positioning hole 1333, and the lower part is fixed by bolts or snap connections. The upper and lower limit fixations are used to enhance the stability between the door body as a whole and the support device.

[0112] Further, such as Figure 12 As shown, the first assembly hole is the first snap-fit ​​installation hole 13311, and the second assembly hole is the second snap-fit ​​installation hole 13321. The door body assembly is fixed by snap-fit ​​installation, which is simple to install, easy to disassemble and replace, and reduces the difficulty of assembly.

[0113] Preferably, if Figure 12As shown, the first buckle mounting hole 13311 is a square stepped hole, the second buckle mounting hole 13321 is a circular hole, and the end cap of the buckle is located in the square stepped hole and does not expose outside, preventing scratching other components and enhancing the overall aesthetics. More preferably, the stepped hole is provided with a positioning groove, which effectively prevents the buckle from moving and disengaging in the mounting hole, and also reduces the assembly difficulty. In order to facilitate processing, the positioning groove is a through positioning groove opened in the stepped part of the stepped hole, which is opened in the middle position of the upper, lower, left and right walls of the stepped hole, and is positioned from four directions to further prevent the buckle from moving and disengaging in the mounting hole.

[0114] Further, as shown in Figure 12 The first longitudinal plate 1331 and the third longitudinal plate 1361 are provided with a reinforcing rib 1372; preferably, the reinforcing rib 1372 is a right-angled trapezoidal plate, the right-angled edge of the plate-shaped reinforcing rib 1372 is connected to the first longitudinal plate 1331, and the lower bottom edge of the plate-shaped reinforcing rib 1372 is connected to the inner wall of the third longitudinal plate 1361. The right-angled trapezoidal plate-shaped reinforcing rib 1372 not only has a reinforcing effect, but also greatly saves materials by being trapezoidal.

[0115] Further, the second support frame further comprises a reinforcing arm 1371 obliquely connected between the upper end of the first longitudinal plate 1331 and the first support frame, so as to enhance the stability of the second support frame.

[0116] The following is a specific description of the structure of the door body.

[0117] As shown in Figures 11-12 The door body assembly 15 comprises a door body 152, and the inner container bottom is provided with a support device, and the door body 152 is fixedly connected with the support device through a connecting structure. The connecting structure stably connects the door body 152 with the support device, prevents the door body 152 from falling off, avoids noise generated by vibration of the door body 152 during operation of the dishwasher, and improves user experience. The door body connecting structure is Figure 10 The door body 152 in the figure is the main body of the door body.

[0118] The connecting structure comprises a first connecting arm 1511 arranged on the side of the door body 152 close to the inner container. Specifically, the first connecting arm 1511 is arranged on the opposite sides of the door body 152. The arrangement of the first connecting arm 1511 makes the connection position of the door body 152 and the support device located on the plane formed by the first connecting arm 1511, reducing the connection difficulty. And the first connecting arm 1511 is arranged on the opposite sides of the door body 152, so that the door body 152 is fixedly connected with the support device at both ends, making the connection of the door body 152 and the support device more reliable.

[0119] Specifically, the first connecting arm 1511 is integrally extended along the length of the connecting structure, which simplifies the molding and manufacturing of the first connecting arm 1511 and increases the strength of the connection with the support device. Alternatively, the first connecting arms 1511 are spaced apart along the length of the connecting structure, which reduces the difficulty of connecting the first connecting arm 1511 to the support device and saves material for manufacturing the first connecting arm 1511.

[0120] The first connecting arm 1511 is provided with a limiting portion. Specifically, the first limiting portion is a limiting protrusion provided at one end of the connecting arm, and the limiting protrusion is plug-fitted and connected to the supporting device. Figure 11 Alternatively, the first limiting portion is a limiting notch provided at one end of the connecting arm, wherein the limiting notch is a U-shaped notch. The first limiting portion not only limits the first connecting arm 1511 and the support device, but also serves to position the support device and the door body 152 for installation, thereby increasing installation efficiency.

[0121] The first connecting arm 1511 is also provided with a connecting portion; specifically, the connecting portion is provided at an end away from the limiting protrusion; the connecting portion is a connecting hole provided on the first connecting arm 1511 for passing a connecting member.

[0123] The engaging bosses or engaging holes may be integrally formed on the connecting arm along its length, or may be spaced apart along its length. The engaging bosses may be integrally injection-molded on the first connecting arm 1511, or the engaging holes may be integrally formed on the first connecting arm 1511. Molding the engaging bosses or engaging holes facilitates manufacturing, while spacing the engaging bosses or engaging holes along the length of the first connecting arm 1511 saves material and further facilitates assembly of the first connecting arm 1511 with the support device.

[0124] Alternatively, the door body 152 is fixedly connected with the supporting device through a connecting piece, the connecting part is a connecting hole provided on the connecting arm for penetrating the connecting piece. The connecting piece is a screw, the screw is fastened to connect the supporting device and the door body 152 by penetrating the connecting hole provided on the first connecting arm 1511. The screw is easy to purchase as a standard part, without the need to redesign a new connecting structure, only the connecting hole needs to be opened on the first connecting arm 1511, and the connecting process is mature and reliable.

[0125] The door body 152 is integrally formed with the connecting structure or detachably connected. The scheme that the door body 152 is integrally formed with the connecting structure can increase the connecting strength of the door body 152 and the connecting structure. The scheme that the door body 152 is detachably connected with the connecting structure makes the door body 152 and the supporting device easy to assemble and convenient to replace and maintain.

[0126] The connecting structure includes a second connecting arm 1512 connecting the door body 152, and the second connecting arm 1512 is bent at one end of the first connecting arm 1511. The connecting strength of the first connecting arm 1511 and the second connecting arm 1512 is increased, so that the connection of the door body 152 and the supporting device is more reliable.

[0127] A plurality of connecting holes are provided on the second connecting arm 1512, and the second connecting arm 1512 is fastened to the door body 152 by a fastener. The connecting piece is a screw, the screw is fastened to the door body 152 by penetrating the connecting hole provided on the second connecting arm 1512. The screw is easy to purchase as a standard part, without the need to redesign a new connecting structure, only the connecting hole needs to be opened on the second connecting arm 1512, and the connecting process is mature and reliable.

[0128] Opposite sides of the door body 152 main body are provided with connecting surfaces connected with the second connecting arm 1512, and the connecting surface is integrally bent at the end of the door body 152.

[0129] Specifically, the dishwasher is provided with a slide rail, the door body 152 is bent to form two first bending parts near the end of the opposite sides of the slide rail towards the side close to the inner container, the free ends of the two first bending parts are bent to form two second bending parts towards the opposite first bending parts; the second connecting arm 1512 is overlapped with the inner wall of the second bending part away from the inner container and then fastened by a fastener. The second bending part is overlapped with the second connecting arm 1512, when the door body 152 is opened, the second bending part will generate a force to the second connecting arm 1512, without generating a force to the fastener, to ensure the reliable and stable connection of the door body 152 and the supporting device. The second bending part is the door body mounting part 1521 shown in the figure.

[0130] The following is a specific description of the assembly relationship between the supporting device and the door body.

[0131] Combined with Figure 1 , Figures 10-12As shown, the front end of the inner container assembly is provided with a door body assembly 15, which is fixedly connected with the supporting device 13 and blocks one side of the inner container. Since the door body 152 has a planar structure as a whole, it is not easy to be fixedly connected with the supporting device perpendicular to the door body, and therefore the door body assembly 15 further comprises a door body connecting piece 151, such as Figure 11 As shown, the door body connecting piece 151 is fixedly connected with the door body 152 and the supporting device respectively; the door body connecting piece at least comprises a first connecting part 1511 connected with the supporting device and a second connecting part 1512 connected with the door body. The first connecting part 1511 and the second connecting part 1512 are two plate-shaped structures arranged vertically and have an angular shape as a whole, one plate is opposite to the door body, and one plate is used for being fixedly connected with the supporting device, so that the assembly between the supporting device and the door body is more stable.

[0139] To facilitate assembly, the door assembly 15 can be first positioned by a positioning structure and then fixedly connected by a fixing structure. The first connecting portion is connected to the support device to limit the relative movement of the door connecting member and the support device. The first connecting portion includes a limiting structure that is connected to the support device, and the support device has a corresponding limiting matching structure.

[0140] Specifically, if Figure 12 As shown, the top edge of the first connecting portion 1511 is provided with a plug-in portion 15111, and a horizontal plate-like structure is provided between the first longitudinal plate 1331 and the second longitudinal plate. The plate-like structure is provided with a positioning port 1333 matching the shape of the plug-in portion. The plug-in portion 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 first snap-fit ​​mounting hole 13311 and the second snap-fit ​​mounting hole 13321, which is more conducive to assembly efficiency.

[0141] The bottom of the support device is provided with a slide rail mounting groove extending perpendicular to the door body direction. The second connecting portion of the door body connecting member 151 blocks one end of the slide rail mounting groove, which can further prevent the slide rail from detaching from the inner tank assembly.

[0142] The supporting device is the core component of the liner assembly. The fixed connection between the door body and the supporting device is more reliable. The supporting device is provided with a connecting structure facing the door body for easy installation. A door body connecting piece is provided between the door body and the supporting device. The door body connecting piece has a positioning and fixed connection structure, which makes the door body assembly more firmly assembled on the liner assembly and easy to disassemble and assemble. When the door body needs to be replaced, it can be replaced by removing the fasteners.

[0143] Example 4

[0144] This embodiment mainly introduces in detail the specific structure of the outer plate assembly structure in which the supporting device cooperates with the outer plate, as well as the assembly relationship between the outer plate and the outer plate.

[0145] The following is a detailed description of the outer plate assembly structure of the support device.

[0146] Combine Figure 5 As shown, the support device provided in this embodiment includes a support body with an extended length, the support body having an assembly structure, and the assembly structure including an outer panel assembly structure. The support body includes a first support frame, the first support frame including 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 end surfaces of the first and second support plates. The outer panel assembly structure is provided on the second support plate 1326, and the outer panel assembly structure includes a plug-in plate 1342 formed by the downward extension of the lower edge of the second support plate 1326. The outer panel assembly structure provided on the support device can also effectively solve the problem of assembling and connecting the bottom bracket and / or the inner container and / or the door body with the outer panel.

[0147] In another approach, Figure 14 As shown, the outer plate positioning portion 1342 is a horizontal positioning platform formed by horizontally extending the bottom edge of the support body toward the outside, and a positioning structure for assembly positioning is provided on the horizontal positioning platform.

[0148] The positioning structure is a positioning protrusion provided on the positioning platform; or, the positioning structure is a positioning groove provided on the positioning platform; or, the positioning structure is a positioning hole provided on the positioning platform, which is positioned and fixed by screws or buckles.

[0149] like Figure 5 and Figure 13 As shown, the outer panel assembly structure further includes side panel mounting holes 1341 defined in the second support plate 1326 and / or the plug-in plate 1342. The side panel mounting holes 1341 correspond to and mate with the fourth snap-fit ​​mounting holes 162 in the outer panel 16. The length / width of the second support plate 1326 is no greater than the corresponding length / width of the outer panel 16. The side of the second support plate 1326 proximal to the outer panel 16 has a smooth mating surface, allowing the outer wall of the second support plate 1326 to fit tightly against the inner wall of the outer panel, facilitating a secure connection.

[0150] Preferably, the side panel mounting hole 1341 in this embodiment corresponds to the position of the fourth snap mounting hole 162 and the first snap mounting hole 13311 to facilitate overall installation. The outer panel, door body assembly, and support device can be connected and fixed together through a snap, which simplifies the setting of parts, makes assembly simple, and facilitates disassembly and replacement.

[0151] The following is a detailed description of the structure of the outer plate:

[0152] like Figures 13-14 As shown, a first connection structure connected to the support device is provided on the outer panel 16. The outer panel body is a plate-like structure provided outside the side panel of the inner liner 11, and the plate-like structure shields the side panel of the inner liner 11 to achieve an aesthetic effect of not exposing the side panel of the inner liner 11. Figure 13 The outer panel 16 is the outer panel body. The outer panel 16 is provided with a first connection structure fixedly connected to the support device, which ensures a stable connection between the outer panel 16 and the support device, preventing the outer panel 16 from falling due to a loose connection. At the same time, it prevents the outer panel 16 from vibrating and generating noise during operation of the dishwasher, thereby improving the user experience.

[0153] Specifically, the first connecting structure includes a connecting arm 161 formed by bending the bottom end of the outer plate 16. The connecting arm 161 is provided with a connecting portion. This provides a connection surface on the outer plate 16 for connection to the support device. The connecting arm 161 also serves to position the support device during assembly, thereby facilitating efficient assembly of the outer plate 16 and the support device. The connecting arm extends integrally or is spaced apart along the length of the bottom end of the plate-like structure.

[0154] The connecting arm 161 is formed by bending the bottom end of the outer panel 16 toward the side opposite to the outer panel 16. The bending of the bottom end of the outer panel 16 toward the side opposite to the outer panel 16 to form the connecting arm 161 prevents the connection between the outer panel 16 and the supporting device from being exposed, thereby not affecting the aesthetics of the dishwasher's interior.

[0155] Alternatively, the connecting arm 161 is formed by bending the bottom end of the outer panel 16 toward the side away from the inner container. The connecting arm 161 is formed by bending the bottom end of the outer panel 16 toward the side away from the inner container. The connecting arm 161 is located on the side of the outer panel 16 away from the inner container rather than between the inner container and the outer panel 16. This increases the assembly connection space, makes the assembly connection between the outer panel 16 and the support device more convenient, and improves assembly efficiency.

[0156] The outer plate 16 is fixedly connected to the support device via a snap-fit ​​structure, wherein the connecting portion is a snap-fit ​​boss or a snap-fit ​​hole provided on the connecting arm 161. The outer plate 16 and the support device are fixedly connected via the snap-fit ​​structure without the need for additional connectors, thus saving costs and accelerating connection and assembly efficiency.

[0157] Specifically, the engaging bosses or engaging holes are integrally extended on the connecting arm 161 along the pulling direction of the dishwasher; or the engaging bosses or engaging holes are spaced apart on the connecting arm 161 along the pulling direction of the dishwasher.

[0158] Alternatively, the outer plate 16 is fixedly connected to the support device via a connector. The connector is a connection hole provided on the connecting arm 161 for receiving the connector. The connector is a screw that passes through the connection hole provided on the connecting arm 161 to securely connect the support device and the outer plate 16. Screws are standard parts that are easily purchased, eliminating the need to redesign a new connection structure. Simply creating a connection hole in the connecting arm 161 is sufficient, and the connection process is mature and reliable.

[0159] The connecting arm 161 is also provided with a positioning portion; specifically, the positioning portion 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 portion facilitates the assembly and positioning connection between the support device and the outer plate 16 body, speeding up the assembly and connection efficiency.

[0160] As another implementation of this embodiment, as shown in FIG13 , a limiting groove is provided on the lower portion of the outer plate 16 body, and the lower portion of the outer plate 16 is connected to the supporting device through the limiting groove.

[0161] The limiting groove is provided on the outer plate 16 along the direction in which the dishwasher is pulled out, and a first limiting portion is provided on the groove wall of the limiting groove near the groove opening. The limiting groove is provided on the outer plate 16 along the direction in which the dishwasher is pulled out, and a first limiting portion is provided on the groove wall near the groove opening. This allows the connecting portion of the support device, which is assembled with the limiting groove, to slide into the limiting groove from one end. The first limiting portion provided on the groove wall of the groove opening restricts the connecting portion of the support device from moving out of the upper groove opening of the limiting groove.

[0162] Specifically, the first limiting portion is a limiting boss extending along the length of the limiting slot. Preferably, the limiting boss is integrally extended along the length of the limiting slot or is spaced apart. The limiting boss is integrally injection-molded onto the slot wall of the limiting slot. The limiting boss extending integrally along the length of the limiting slot facilitates molding and manufacturing, while the limiting boss spaced apart along the length of the limiting slot saves material for manufacturing the limiting boss and further facilitates assembly of the limiting slot and the support device.

[0163] The limiting groove is further provided with a second limiting portion, which is a limiting wall provided at one end of the limiting groove in the longitudinal direction. The second limiting portion prevents the connecting portion of the supporting device from moving out of the end in the longitudinal direction of the limiting groove.

[0164] Specifically, the limiting wall and the limiting groove are formed integrally, that is, one end of the limiting groove in the longitudinal direction is provided with an opening for the connection portion of the support device to be installed therein, and the other end is closed.

[0165] The connecting part is arranged on the end of the limiting groove away from the limiting wall, and the relative position of the connecting part of the supporting device and the connecting part of the limiting groove is clamped and fixed, so that the supporting device is stably connected with the outer side plate 16.

[0166] The connecting part is arranged on the end of the limiting groove away from the limiting wall, and the relative position of the connecting part of the supporting device and the connecting part of the limiting groove is clamped and fixed, so that the supporting device is stably connected with the outer side plate 16.

[0167] Alternatively, the limiting groove is arranged on the outer side plate 16 in the pulling direction of the dishwasher, and the connecting part is arranged in the limiting groove. The connecting part of the supporting device is firmly fixed in the limiting groove through the connecting part, so that the lower part of the outer side plate 16 is stably connected with the supporting device, and the outer side plate 16 is prevented from falling due to unstable installation.

[0168] Specifically, the outer side plate 16 is fixedly connected with the supporting device through a clamping structure, and the connecting part is a clamping boss or a clamping hole arranged on the groove wall of the limiting groove. The outer side plate 16 and the supporting device are fixedly connected through the clamping structure, without the need for additional connecting parts, thereby saving costs and accelerating the connection and assembly efficiency.

[0169] Further, the clamping boss or the clamping hole is integrally arranged on the groove wall of the limiting groove in the pulling direction of the dishwasher; or the clamping boss or the clamping hole is arranged on the connecting arm in the pulling direction of the dishwasher. The clamping boss is integrally injection molded on the groove wall of the limiting groove, or the clamping hole is integrally arranged on the groove wall of the limiting groove. The clamping boss or the clamping hole is easy to form and manufacture, and the clamping boss or the clamping hole is arranged in the length direction of the limiting groove, thereby saving the manufacturing materials of the clamping boss and making the assembly of the limiting groove and the supporting device easier.

[0170] As another embodiment of the present embodiment, the outer side plate 16 is fixedly connected with the supporting device through a connecting part, and the connecting part is a connecting hole arranged on the groove wall of the limiting groove for penetrating the connecting part. The connecting part is a screw, and the screw is tightly connected with the supporting device and the outer side plate 16 by penetrating the connecting hole arranged on the groove wall of the limiting groove. The screw is a standard part and is easy to purchase, and a new connecting structure does not need to be designed. Only the connecting hole needs to be arranged on the groove wall of the limiting groove, and the connecting process is mature and reliable.

[0171] The limiting groove is integrally bent at the lower end of the outer side plate 16, and the connecting strength of the limiting groove and the outer side plate 16 is large, so that the connection between the outer side plate 16 and the limiting groove is more stable.

[0172] Specifically, the limiting groove is formed by bending the lower end of the outer plate 16 toward the opposite outer plate 16 to form a U-shaped groove 161. The connection position between the outer plate 16 and the supporting device will not be exposed, and the aesthetics of the dishwasher inner tank will not be affected.

[0173] As another implementation of this embodiment, the limiting groove is formed by bending the bottom end of the outer plate 16 toward the side away from the inner container to form a U-shaped groove 161. The bottom end of the outer plate 16 is bent toward the side away from the inner container to form the limiting groove. The limiting groove is located on the side of the outer plate 16 body away from the inner container rather than between the inner container and the outer plate 16. This increases the assembly connection space, makes the assembly connection between the outer plate 16 and the support device more convenient, and improves assembly efficiency.

[0174] Alternatively, the connecting portion is a connecting hole provided on the outer plate 16 or the wall of the retaining groove for receiving a connecting member. The connecting member can be a standard part such as a bolt or screw. Alternatively, the connecting member can be a clip, and the connecting hole is a clip mounting hole provided on the outer plate 16 or the wall of the retaining groove. The clip is passed through the clip mounting hole to securely connect the outer plate 16 to the support device. The clip mounting hole is located at the fourth clip mounting hole 162.

[0175] Furthermore, a slide rail is provided along the drawer direction of the dishwasher, and a limit structure is provided at one end of the slide rail near the dishwasher door. An escape notch 164 is provided at one end of the outer panel 16 near the limit structure to avoid the limit structure. The escape notch 164 not only avoids the limit structure at the end of the slide rail, but also cooperates with the limit structure at the end of the slide rail to limit the position.

[0176] like Figure 15 As shown, the upper end of the outer panel 16 is provided with a second connecting structure, and the second connecting structure is connected to the sealing frame 14 provided at the opening of the inner container. That is, the upper end of the outer panel 16 is connected to the inner container opening through the sealing frame provided at the inner container opening. By providing a first connecting structure at the lower portion of the outer panel 16 to be fixedly connected to the support device, and providing a second connecting structure at the upper portion of the outer panel 16 to be fixedly connected to the sealing frame 14 provided at the top opening of the inner container, the outer panel 16 is further firmly provided on the outside of the inner container, so that the outer panel 16 will not generate vibration noise during the operation of the dishwasher, and will not cause the unfixed end to shake and generate noise due to only fixing one end while not fixing the other end.

[0177] Specifically, the upper portion of the outer panel 16 is pluggably fixedly connected to the sealing frame 14. The second connection structure includes a plug-in portion and a positioning portion, with the positioning portion disposed at the bottom end of the plug-in portion. The plug-in connection between the upper portion of the outer panel 16 and the sealing frame eliminates the need for additional connectors, resulting in efficient assembly. The positioning portion serves as an assembly positioning mechanism, allowing the installer to quickly determine whether the outer panel 16 and the sealing frame 14 are properly plugged in, reducing installation time.

[0178] Furthermore, the plug-in portion and / or positioning portion are integrally extended or spaced apart from the upper portion of the outer panel 16 along the direction in which the dishwasher is pulled out. The plug-in portion and / or positioning portion are integrally extended from the upper portion of the outer panel 16 along the direction in which the dishwasher is pulled out, facilitating processing and molding. The plug-in portion and / or positioning portion are spaced apart from each other along the direction in which the dishwasher is pulled out, reducing the difficulty of plug-in connection and making assembly of the upper portion of the outer panel 16 and the sealing frame 14 easier.

[0179] The upper end of the outer panel 16 is bent toward the outside of the inner container to form a first bend. The free end of the first bend is bent horizontally toward the inside of the inner container to form a horizontal bend. The free end of the horizontal bend is bent vertically upward to form a vertical bend. The horizontal bend serves as a positioning portion, and the vertical bend serves as a plug-in portion. Preferably, the first bend is an arcuate bend. The plug-in portion and the positioning portion are integrally bent from the upper portion of the side wall body, thereby increasing the connection strength between the plug-in portion and / or positioning portion and the outer panel 16. The provision of the first bend allows the outer panel 16 to approach the inner container, bringing the outer panel 16 closer to the inner container, reducing the space occupied by the outer panel 16, and increasing the internal space of the inner container.

[0180] As an implementation method of this embodiment, the drawer dishwasher is provided with a photoelectric detection device for detecting whether the door of the drawer dishwasher is open or closed, and the outer panel 16 is provided with a light path avoidance hole for the light path emitted by the photoelectric detection device or the light path reflected to the photoelectric detection device to pass through. The provision of the photoelectric detection device allows the user to clearly understand the degree of closure of the dishwasher door, preventing the user from forgetting to close the dishwasher door or the dishwasher door from being improperly closed. Further, due to the improper closure of the dishwasher door, the washing water splashes out of the door when the dishwasher is working, thereby preventing the user from affecting 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.

[0181] The following is a detailed description of the assembly relationship between the support device and the outer plate.

[0182] Combine Figure 1 and Figure 2The outer panels are disposed on opposite sides of the inner container, and the support device is connected to the outer panels. Since the support device 13 includes a first support device and a second support device, the outer panels 16 also include a first outer panel disposed on one side of the first support device and a second outer panel disposed on one side of the second support device, and the two outer panels are symmetrically disposed.

[0183] The outer panel needs to be fixed on the side of the support away from the inner tank to play a decorative role. Figure 5 As shown, the support device at least includes an outer plate positioning portion 1342 positioned and connected to the outer plate, and the outer plate has an outer plate positioning matching portion positioned and connected to the support device.

[0184] like Figure 5 As shown, the outer plate positioning portion 1342 includes a vertical bottom edge provided at the bottom edge of the support device and extending downward, and the positioning matching portion of the outer plate includes at least a positioning groove provided at the bottom, as shown in FIG. Figure 12 As shown, the positioning groove is a U-shaped groove 161, and the U-shaped groove 161 is formed by bending the bottom edge of the outer plate body toward the supporting device to form a groove structure. The width of the U-shaped groove matches the thickness of the outer plate positioning part 1342, so that the outer plate positioning part of the supporting device can be immersed in the positioning groove.

[0185] Another embodiment is as follows: Figure 14 As shown, the outer plate positioning portion 1342 includes a positioning platform arranged at the bottom edge of the support device and extending toward the outer plate. The position matching structure of the outer plate at least includes a folded edge arranged at the bottom toward the support device, and the folded edge is arranged above the positioning platform.

[0186] The support device needs to be fixedly connected after the outer plate is positioned to ensure that the outer plate will not fall off. The support device also includes an outer plate connecting portion 1341 fixedly connected to the outer plate, and the outer plate 16 has an outer plate connecting matching portion fixedly connected to the support device 13.

[0187] 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 is matched with the sealing frame.

[0188] like Figure 13As shown, the outer panel 16 and the support device 13 each have corresponding mounting holes, which are aligned and then fasteners are inserted to securely connect them. This structure can be provided together with the door assembly structure, and a fourth snap-fit ​​mounting hole 162 corresponding to the first snap-fit ​​mounting hole 13311 is provided on the outer panel. The snap-fit ​​can securely connect the outer panel, the support device, and the door body together, reducing the number of fasteners required and facilitating assembly. Alternatively, the fasteners are screws, and the mounting holes are screw holes. At least one screw hole is provided at the corresponding positions of the support device and the outer panel, and multiple screw holes can also be provided to facilitate structural fixation.

[0189] Since the support device has many installation structures, some installation structures need to be covered to prevent the structure from being exposed and causing unsightly appearance. However, some structures or functions cannot be covered and need to be avoided. The outer plate has a avoidance structure. Figure 13 As shown, the supporting device is provided with a light guide column installation position, and the outer panel has an avoidance hole for avoiding the light path; the outer panel includes a first avoidance hole 1631 and a second avoidance hole 1632, the first avoidance hole 1631 avoids the emission light path, and the second avoidance hole avoids the reflection light path 1632, and a light reflecting part corresponding to the light path is provided on the inner wall of the box, and the position of the door body is detected by reflection.

[0190] In addition, due to the decorative function of the outer panel, more structures should be covered as much as possible to ensure aesthetics. A slide rail connection part is provided at the bottom of the support device and is fixedly connected to the slide rail. The outer panel covers the slide rail connection part and part of the slide rail from the side.

[0191] Since one end of the supporting slide rail has a limiting protrusion, the slide rail connecting part has a limiting notch that abuts against the limiting protrusion, and the outer plate has an avoidance notch that matches the shape of the limiting notch. If no avoidance is performed, the limiting notch will not be able to limit the slide rail firmly, and the plate at the limiting notch is relatively thin and is not sufficient to abut against the limiting protrusion.

[0192] The outer panel is square as a whole, and the length / width of the outer panel is not less than the length / width corresponding to the supporting device, so as to be able to cover the structure of the supporting device; the supporting device has a smooth mating surface facing the outer panel, and the outer panel fits tightly on the mating surface and completely covers the mating surface.

[0193] The outer panel can form a sliding fit with the support device during assembly through positioning structures such as positioning grooves. The assembly method is simple and can ensure the accuracy of positioning. The outer panel is fixed to the support device through the connecting structure between the door body and the support device, reducing the setting of installation parts, saving costs, and reducing assembly steps.

[0194] Example 5

[0195] This embodiment mainly introduces in detail the specific structure of the light guide column assembly structure in which the support device and the light guide column cooperate.

[0196] An LED lamp is provided on the circuit board inside the dishwasher, and the light emitted by the LED lamp 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 provided on the support body, which is used to install the light guide column to detect the position of the door body.

[0197] Specifically, the supporting body includes a first supporting frame and a second supporting frame fixedly connected to one end of the first supporting frame, the second supporting frame includes a longitudinal plate vertically arranged on the first supporting frame, and the first light guide column mounting position and the second light guide column mounting position are light guide column mounting holes arranged longitudinally on the longitudinal plate.

[0198] Combine Figure 10 、 Figure 12 and Figure 16 As shown, the light guide column mounting hole includes a first mounting hole 13312 and a second mounting hole 13313 that are opposite and horizontally spaced a certain distance apart. The two mounting holes are spaced apart to achieve a more stable mounting and fixing of the light guide column.

[0199] Further, such as Figure 12 As shown, the longitudinal plate includes the first longitudinal plate 1331 and the second longitudinal plate in Example 3. The first longitudinal plate and the second longitudinal plate are arranged in parallel and spaced apart. The first mounting hole 13312 is arranged on the first longitudinal plate 1331, and the second mounting hole 13313 is arranged on the second longitudinal plate corresponding to the first mounting hole 13312.

[0200] Preferably, combined Figure 10 and Figure 16 As shown, a third longitudinal plate 1361 vertically connected to the first longitudinal plate 1331 is provided above the support column, 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.

[0201] Specifically, such as Figure 16 As shown, the first mounting hole 13312 is a circular hole provided on the first longitudinal plate 1331 , and the second mounting hole 13313 is an arc-shaped hole correspondingly provided on the upper longitudinal plate 1362 .

[0202] Preferably, Figure 10 As shown, the light guide column assembly structure also includes a light guide column support plate for supporting the light guide column to prevent the light guide column from detaching from the light guide column mounting position and falling from the gap between the first longitudinal plate and the second longitudinal plate. The light guide column support plate includes a first light guide column support plate 1363 located below the first light guide column mounting position, and a second light guide column support plate 1364 located below the second light guide column mounting position.

[0203] The first light guide column support plate 1363 and the second light guide column support plate 1364 are connected between the first longitudinal plate 1331 and the second longitudinal plate to support the light guide columns and enhance the stability of the first longitudinal plate and the second longitudinal plate.

[0204] The first light guide mounting position is used to mount a first light guide for light entry, and the second light guide mounting position is used to mount a second light guide for light exit. Light exits from the first light guide and is refracted back to the second light guide by a corresponding reflective element on the housing, thereby detecting whether the door is fully closed. If the light is detected to be refracted back to the second light guide, the door can be determined to be fully closed.

[0205] Example 6

[0206] This embodiment will introduce in detail the specific structure of the inner liner of the present invention and how the inner liner is made.

[0207] like Figures 18-19 As shown, the inner liner 11 includes a bottom plate and a side plate assembly arranged 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 a convex structure protruding from the inside of the inner liner 11 to the outside.

[0208] In the above solution, the inner liner 11 is configured as a convex structure from the inside of the inner liner to the outside, thereby increasing the capacity of the inner liner 11 and realizing the expansion of the inner liner.

[0209] Preferably, the inner pot 11 is slidably arranged in the cabinet of the dishwasher, and the side panel assembly includes two side panels extending along the sliding direction of the inner pot 11, and the two side panels are both configured as convex structures protruding in a direction away from the opposite side panel.

[0210] In the above solution, the two side panels are relatively arranged to form an outward convex structure, thereby increasing the size of the inner container in a direction perpendicular to the sliding direction of the inner container and increasing the internal space of the inner container.

[0211] Preferably, the inner container includes a front plate and a rear plate respectively connected to both ends of the two side plates, the middle portion of the side plates protrudes outward, and the side plates are bent and extended toward the front plate and the rear plate on both sides along the sliding direction of the inner container.

[0212] In the above solution, the side panels are formed by stamping a large area in the middle of the side panels, creating a structure with a convex center and a retracted periphery, thereby increasing the internal volume of the liner. Specifically, a convex protrusion 114 is stamped on the side panels in a direction opposite to the opposite side panels, forming a shell structure with a convex bottom wall and a peripheral wall extending toward the opposite side panel. In this method, stamping a large area in the middle of the side panels increases the internal volume of the liner.

[0213] Alternatively, the side panel is configured by bending and concave the lower edge of the side panel toward the interior of the inner tank, forming a structure in which the upper portion of the side panel is convex and the lower portion is concave. The concave structure at the lower portion is used to avoid the slide rail or the support device, and the convex structure at the upper portion increases the internal space of the inner tank.

[0214] Preferably, the side panels are provided with first extension surfaces on both sides along the sliding direction of the inner container, which are bent toward the front panel and the rear panel to connect the front panel and the rear panel respectively. The middle portion of the side panels is a planar structure, and the two sides of the planar structure are smoothly connected to the first extension surfaces of the corresponding sides by first curved surfaces. The middle portion of the side panels is stamped into a convex plane, and the curved surface transitions to the side edge of the side panels. In this way, the stamping strength of the side panels is low, the inner container produced is high in strength and quality, and the smooth transition of the inner container has a good overall gloss and beautiful appearance. Through the design on the first extension surface, the joint position is transferred from the corner between the side panel and the front and rear panels to the plane where the front panel or the rear panel is located, which facilitates and simplifies the connection between the side panels and the front and rear panels.

[0215] The side panels are flat in the middle, transitioning to the side panel edges via smooth first curved surfaces on either side of the side panel's sliding direction. This curved surface transitions from the side panel's center flat surface to the side panel's edge, reducing the panel's stamping strength. This results in a strong, high-quality inner container, and a smooth transition that creates a lustrous, attractive appearance.

[0216] In this embodiment, the inner container has a drawer structure and includes a front panel and a rear panel connected to the ends of two side panels. A first extension surface is provided on each side of the side panels, extending and bending toward the front panel and the rear panel, respectively. The first extension surface is connected to the corresponding front panel or rear panel. The bottom wall of the inner container is connected to the first extension surface via a smooth first curved surface. The design on the first extension surface shifts the joint location from the corner between the side panel and the front and rear panels to the plane of the front or rear panel, simplifying the connection between the side panels and the front and rear panels.

[0217] See also Figure 19 As shown, in one solution, after the side panels are stamped and formed 114, a concave surface 115 is formed at the bottom of the side panels, which is concave toward the interior of the inner container. The concave surface 115 is used to avoid the slide rail or support device of the dishwasher.

[0218] In the above solution, the inner tank is formed with a recessed surface for avoiding the slide rails or supporting devices of the dishwasher, thereby making full use of the space inside the dishwasher shell and facilitating the expansion of the inner tank.

[0219] Preferably, the recessed surface 115 includes a recessed surface that gradually indents 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, which is longitudinally cut through a vertical surface perpendicular to the side panel on which it is located, includes, from top to bottom, a first curve 1153 with a center of curvature inside the inner liner and a second curve 1154 with a center of curvature outside the inner liner. The first curve and the second curve transition smoothly. 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. With this structural design, the edges of the convex profile, or the two bends of the recessed surface 115, have the same tensile strength, the plate is evenly stretched, and the thickness is uniform, thereby preventing local transitional stretching from affecting the quality of the inner liner.

[0220] See also Figure 18 As shown, in another structure, the concave surface is a concave surface directly punched from the bottom of the side panel toward the interior of the inner container. The concave surface includes a horizontal bending surface 1151 formed by bending the bottom wall of the side panel from top to bottom toward the interior of the inner container, and a vertical bending surface 1152 formed by bending the end of the horizontal bending surface 1151 vertically downward. The horizontal bending surface and the vertical bending surface are connected and transitioned by a smooth arc surface. This structure is similar to Figure 19 The structure is different, Figure 19 The reason is that the convex pressing of the stamping indirectly forms a concave surface. Because the pressing profile is large, the stamping strength cannot be high, so it has no horizontal bending surface. Figure 16 Because the recessed surface is directly stamped, the stamping area is small, and a recessed surface with a horizontal curved surface and a vertical curved surface can be stamped. The support device is provided with a slide rail mounting portion, 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 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 curved surface, and the slide rail mounting groove side plates are arranged parallel to the vertical curved surface.

[0221] Furthermore, a relief step is provided at the upper end of the side panel of the slide rail mounting slot on the side closest to the inner container. The relief step extends along the length of the slide rail mounting slot and is formed by recessing the upper end of the side panel of the slide rail mounting slot toward the side away from the inner container. Specifically, the recessed step includes a first bend formed by bending the upper end of the side panel of the slide rail mounting slot toward the side away from the inner container, the free end of the first bend being bent upward to form a second bend; the free end of the second bend being connected to the top plate of the slide rail mounting slot.

[0222] Preferably, the bottom edge of the side panel is provided with a second extension surface that bends and extends toward the bottom panel, and the recessed surface smoothly transitions to the second extension surface, which is connected to the bottom panel of the inner container.

[0223] Furthermore, the front and / or rear panels of the liner are similar to the two side panels, and are configured to bulge outward toward the exterior of the liner, allowing for expansion of the liner. Their structure can be similar to the two side panels, with the lower recessed surface of the rear panel providing clearance for the rear waterway. This will not be further elaborated here.

[0224] As an implementation method of this embodiment, Figure 17 As shown, in this embodiment, the inner tank 11 is composed of three splicing parts, including a first splicing part, a second splicing part and a third splicing part. The second splicing part and the third splicing part are located on both sides of the first splicing part, parallel to the pulling direction of the dishwasher, and the splicing position of the second splicing part / the third splicing part and the first splicing part is located on a plane.

[0225] The first assembly component includes a bottom plate 110 of the inner container, and a front plate 112 and a rear plate 113 connected to the bottom plate 110 and perpendicular to the direction in which the dishwasher is pulled out.

[0226] The second splicing component / third splicing component includes a side panel 111 parallel to the pulling direction of the dishwasher. The second splicing component / third splicing component also includes an extension connected to the side panel 111 and bent toward the opposite side panel. The extension is connected to the first splicing component. The extension includes a rounded corner structure between the inner tank wall surfaces. The setting of the extension ensures that the splicing position of the second splicing component / third splicing component and the first splicing component is located on a plane.

[0227] The second splicing component / the third splicing component is stamped as a whole, and the extension portion includes a first extension surface 1111 located on the bottom surface of the side panel 111 and a second extension surface 1112 located on the side surface of the side panel 111. After forming the rounded structure between the inner tank wall surfaces, the extension portion continues to extend straight toward the opposite side panel. 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.

[0228] The side panel 111 of the second / third splicing component includes a recessed surface 115, which is a receiving portion recessed toward the center of the inner container. The receiving portion can be used to avoid a slide rail or a supporting device, making it easier for the inner container to be pushed into or pulled out of the dishwasher housing, and for taking and placing tableware in the dishwasher.

[0229] Same as the previous implementation, Figure 18The recessed surface 115 includes a horizontal bending surface 1151 that is first bent toward the inside of the inner container from top to bottom, and a vertical bending surface 1152 that is formed by bending vertically downward at the end of the horizontal bending surface 1151. The horizontal bending surface 1151 and the vertical bending surface 1152 are connected and transitioned by a smooth arc surface.

[0230] 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.

[0231] Preferably, in this embodiment, a first extension surface 1111 that bends and extends toward the bottom plate 110 is provided at the bottom of the vertical bending surface 1152 , and the first extension surface 1111 is connected to a corresponding side edge of the bottom plate 110 .

[0232] In the above scheme, the bottom edge of the horizontal bending surface 1151 is bent toward the bottom to form the first extension surface 1111. The first extension surface 1111 is preferably in the same plane as the bottom plate 110. In this way, the joint position of the bottom plate 110 and the lower edge of the side plate 111 is on the plane, not at the corner, which facilitates the alignment of the splicing parts and moves the welding position to the plane, reducing the difficulty of welding.

[0233] Preferably, second extension surfaces 1112 that bend and extend toward the front plate 112 and the rear plate 113 are respectively provided on both sides of the side plate 111 , and the second extension surfaces 1112 are connected to the corresponding front plate 112 or rear plate 113 .

[0234] In the above scheme, both sides of the side panel 111 are bent toward the front panel 112 and the rear panel 113 to form the second extension surface 1112. The side where the second extension surface 1112 is spliced ​​with the front panel 112 or the rear panel 113 is in the same plane as the front panel 112 or the rear panel 113, thereby avoiding the corners and facilitating welding and fixation.

[0235] In this embodiment, the design of the second extension surface 1112 prevents splicing on the recessed surface 1115 , and the splicing position is transferred to a plane, thereby simplifying the welding process.

[0236] The edge of the first splicing component at the splicing position is bent toward the outside of the inner liner to form a first connecting surface, and the edge of the second splicing component / the third splicing component at the splicing position is bent toward the outside of the inner liner body to form a second connecting surface. The first connecting surface and the second connecting surface are welded after they are tightly attached.

[0237] The edge of the first splicing component at the splicing position is bent toward the outside of the inner liner to form a first connecting surface, and the edge of the second splicing component / the third splicing component at the splicing position is bent toward the outside of the inner liner body to form a second connecting surface. The first connecting surface and the second connecting surface are welded after they are tightly attached.

[0238] The second splicing component / the third splicing component at the splicing position is connected to the first splicing component at the splicing position by rolling. The edge of the first splicing component at the splicing position is bent toward the outside of the inner liner body to form a first connecting surface. The first connecting surface is U-shaped with an opening toward the center of the inner liner. The edge of the second splicing component / the third splicing component at the splicing position is bent toward the outside of the inner liner, extended toward the opposite side splicing component, and then bent upward to form a second connecting surface. The second connecting surface is U-shaped with an opening facing opposite to the first connecting surface. The first connecting surface and the second connecting surface are nested and connected.

[0239] like Figure 20 As shown, a sealing frame 14 is provided at the top opening of the inner liner 11. A mounting groove for assembling the top opening of the inner liner is provided at the bottom of the sealing frame 14, near the inner liner. A water retaining 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 provision of the water retaining structure 117 effectively prevents wash water from entering the gap between the sealing frame 14 and the wall of the inner liner 11 and flushing the sealing structure, thereby extending the service life of the sealing structure and improving the overall user experience of the product.

[0240] In order to avoid noise caused by friction during assembly between the sealing frame 14 and the inner container 11 and to improve the tightness of the seal, a sealing ring 142 is provided between the sealing frame 14 and the inner container 11 .

[0241] like Figure 20 It is shown that the water retaining structure 117 is a convex structure recessed toward the center of the inner tank, and the surface of the convex structure is arc-shaped. A receiving portion is provided on the groove wall of the installation groove of the sealing frame 14, and the water retaining structure 117 is snap-connected with the receiving portion. The receiving portion is a groove whose groove wall is recessed toward the center of the inner tank, and the inner surface of the groove is consistent with the outer surface shape of the water retaining structure 117, which facilitates the installation of the sealing frame 14. While increasing the density of the sealing structure, it 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.

[0242] The water retaining structure may also be located at the lower edge of the sealing frame. The water retaining structure is a convex structure that is recessed toward the center of the inner container. The convex structure is located at the lower edge of the sealing frame.

[0243] The part of the top surface of the inner container 11 matched with the sealing frame 14 is provided with a folding structure 116 outward of the inner container, the end of the folding structure 116 has an angle with the wall surface of the inner container 11, and is inclined to the outer side of the inner container. The slot wall opposite to the accommodating portion of the mounting slot of the sealing frame 14 is provided with a through hole 143, the lower surface of the through hole 143 is longer than the upper surface, and the lower surface protrudes towards the direction close to the inner container 11. The end of the folding structure 116 is clamped on the lower surface of the through hole 143. When the sealing frame 14 is disassembled, a tool smaller than the diameter of the through hole 143 is used to enter the through hole 143 from the side far away from the wall surface of the inner container, and the end of the folding structure 1117 is pushed away from the lower surface of the through hole 143, which is simple to operate and brings good user experience.

[0244] As a further limitation of the embodiment, the folding structure 116 on the top surface of the inner container 11 is integrally arranged or arranged at intervals, and the through hole 143 on the sealing frame 14 corresponds to the folding structure 116 one by one, and cooperates with each other, which is beneficial to the demolding of the sealing frame 14 and enhances the compactness of the sealing.

[0245] As another embodiment of the embodiment, a limiting boss is arranged on the slot wall of the mounting slot of the sealing frame 14 opposite to the accommodating portion, and the end of the folding structure 116 is clamped on the limiting boss. Specifically, the folding structure 116 / limiting boss is integrally arranged or arranged at intervals. In the embodiment, the inner container 11 includes four side plates with straight flat top surfaces, the side plates are connected by rounded transition side plates, and the water blocking structure 117 is located on the upper part of the side plate.

[0246] The sealing frame 14 can also be integrally injection molded on the top of the inner container to increase the connection strength of the inner container and the sealing frame.

[0247] The bottom side of the sealing frame 14 away from the inner container is also provided with a plug-in slot for mounting the upper end of the outer side plate, the plug-in slot is plug-in fixedly assembled with the plug-in portion of the upper end of the outer side plate, and the upper part of the outer side plate is fixedly connected. The plug-in slot is integrally arranged or arranged at intervals along the length direction of the bottom of the sealing frame, and the plug-in slot is arranged one by one corresponding to the plug-in arm.
