Description

Technical Field

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

[0002] As people's living standards improve, more and more families start to use dishwashers to wash dishes. In the past, when opening the door of a front-loading dishwasher, users had to bend down or even squat to fully open the door, which was tiring for users to use. In addition, when putting dishes to be washed in a front-loading dishwasher, since there is no enclosure around it, the residual soup from the dishes to be washed can easily spill out of the dishwasher, which will undoubtedly give users a poor user experience. With the development of dishwasher technology, drawer-type dishwashers were invented. Drawer-type dishwashers use a pull-out door design, which does not require bending down or squatting to open the dishwasher. It is more ergonomically designed, and when putting dishes to be washed in, there is no need to worry about the residual soup from the dishes to be washed spilling out of the dishwasher because of the enclosure design.

[0003] The drawer-type dishwasher includes an inner tank. In order to reduce the noise generated by the vibration when the dishwasher is working, a buffer sound insulation material is set on the outer wall of the inner tank. In order not to affect the beauty of the inner tank of the dishwasher, an outer plate is set on the outside of the inner tank to cover the buffer sound insulation material. In the past, the inner tank of the dishwasher was integrally injection-molded with plastic, and the outer plate was integrally injection-molded and connected with the inner tank. Now, in order to improve the quality and service life of the inner tank, the inner tank adopts a metal inner tank made of metal material. How to fix the outer plate with the metal inner tank is a problem that people in this technical field need to solve.

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

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 the first embodiment, 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 part of the side edge of the first support plate 1325 inward.

[0091] Further, such as Figure 8 As shown, the second slide rail connecting 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.

[0095] The following is a detailed description of the corresponding assembly structures and assembly relationships of the slide rail and the support device.

[0096] like Figure 8 As shown, the slide rail 2 includes an upper sliding member 21 and a lower sliding member 22 that can move relatively. 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 arranged 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 of them.

[0097] The inner container assembly is fixedly mounted with the upper slide member 21 via the support device 13. Accordingly, the drawer assembly includes two sets of slide rails arranged symmetrically, and the support device 13 includes a first support device and a second support device respectively matched with the two sets of slide rails. The following only describes the matching between the first support device and the slide rail.

[0098] 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 supporting 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 supporting device in the left and right directions.

[0099] like Figure 8 As shown, one end of the rear portion 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 extending upward and then forward, and is open forward. The supporting device is provided with a hook plate 1322 cooperating with the hanging ear 211, and 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.

[0100] 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, the end cap 212 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 matching 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.

[0101] like Figure 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.

[0102] 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 abuts against the supporting groove 2122 and supports the end cap 212 to limit the relative upward and downward movement of the end cap and the support device.

[0103] During the assembly process, the slide rail is first hooked on the rear end of the support device through the rear end hook, at which time the slide rail is also placed in the slide rail mounting groove, and then the front end of the slide rail is fixed and installed through 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 sliding member can slide relative to the lower sliding member, a certain limit is required to prevent the slide rail from slipping. The slide rail also includes a fixedly arranged slide rail support frame 24, and a limit mechanism is arranged 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.

[0104] like Figure 8 As shown, the limiting mechanism includes a limiting member 25 arranged on the slide rail support frame, and 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, the first part is fixedly connected to the slide rail support frame, the second part has a claw, and is rotatably arranged on the first part, the second part has a rotating shaft, and the first part has a rotating shaft groove for accommodating the rotating shaft. A protrusion is arranged at the rear end of the first part to limit the further backward rotation of the second part. The rear end of the support device is provided with a limiting rod 135 that can be immersed in the claw / disengaged from the claw. When the limiting rod 135 is immersed in 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 will be disengaged from the claw, and the claw stays at this position waiting for the limiting rod to be immersed in the claw again.

[0105] The dishwasher further comprises a box body, which has an opening on the side, and the drawer assembly is pushed and pulled from the open side, and the slide rail comprises a slide rail support frame 24, and the slide rail support frame 24 is fixedly connected to the inner wall of the box body.

[0106] The slide rail is fixedly connected to the support device through limit stops in multiple directions, which ensures the overall coordination between 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, firstly 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 rear 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 arranged at the rear end of the support device, which can limit the position of the inner tank assembly when it is pushed into the box body, and 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.

The end cap of the buckle is located in the square stepped countersunk hole and will not be exposed to the outside, so as to prevent scratching other parts and enhance the overall aesthetics. More preferably, a positioning groove is provided in the stepped countersunk hole, and the positioning groove is provided to effectively prevent the buckle from moving or detaching in the mounting hole, and also reduce the difficulty of assembly. For the convenience of processing, the positioning groove is a through positioning groove provided in the stepped part of the stepped countersunk hole. The through positioning groove is provided in the middle of the upper, lower, left and right wall surfaces of the stepped countersunk hole, and is fully positioned from four directions to further prevent the buckle from moving or detaching in the mounting hole.

[0118] Further, such as Fig.12 As shown, 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 lower bottom long side of the plate-shaped reinforcing rib 1372 is connected to the inner wall of the third longitudinal plate 1361.

[0122] The connection structure includes a first connection arm 1511 disposed on one side of the door body 152 close to the inner container. Specifically, the first connection arm 1511 is disposed on opposite sides of the door body 152. The first connection arm 1511 is disposed so that the connection position between the door body 152 and the support device is located on the plane formed by the first connection arm 1511, thereby reducing the difficulty of connection. The first connection arm 1511 is disposed on opposite sides of the door body 152 so 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.

[0123] Specifically, the first connecting arm 1511 is integrally extended along the length direction of the connecting structure, and the molding and manufacturing of the first connecting arm 1511 is simpler, and the connection strength with the supporting device is increased. Alternatively, the first connecting arm 1511 is spaced along the length direction of the connecting structure, which reduces the difficulty of connecting the first connecting arm 1511 with the supporting device and saves the manufacturing material of the first connecting arm 1511.

[0124] 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 with the supporting device.

The connection process is mature and reliable.

[0129] The door body 152 and the connecting structure are integrally formed or detachably connected. The solution of the door body 152 and the connecting structure being integrally formed can increase the connection strength between the door body 152 and the connecting structure. The solution of the door body 152 and the connecting structure being detachably connected makes it easy to assemble the door body 152 and the supporting device, and is convenient for replacement and maintenance.

[0130] The connection structure includes a second connection arm 1512 connected to the door body 152, and the second connection arm 1512 is formed by bending one end of the first connection arm 1511.

When the door body needs to be replaced, it can be replaced by removing the fasteners.

[0147] Embodiment 4

[0148] 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, and the assembly relationship between the outer plate and the outer plate.

[0149] The following is a detailed description of the outer side plate assembly structure of the support device.

The outer plate assembly structure arranged on the support device can also effectively solve the assembly connection problem between the bottom bracket and / or the inner liner and / or the door body and the outer plate.

[0151] In another scheme, if Fig.14 As shown, the outer plate positioning portion 1342 is a horizontal positioning platform formed by horizontally extending the bottom edge of the supporting body toward the outside, and a positioning structure for assembly positioning is provided on the horizontal positioning platform.

[0152] The positioning structure is a positioning protrusion arranged on the positioning platform; or, the positioning structure is a positioning groove arranged on the positioning platform; or, the positioning structure is a positioning hole arranged on the positioning platform, which is positioned and fixed by screws or buckles.

The length / width of the second support plate 1326 is not greater than the corresponding length / width of the outer panel 16, and the second support plate 1326 has a smooth mating surface on the side close to the outer panel 16, so that the outer wall of the second support plate 1326 fits tightly with the inner wall of the outer panel for easy fixed connection.

[0154] Preferably, the side panel mounting hole 1341 in this embodiment corresponds to the positions 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, simple assembly, and easy disassembly and replacement.

[0155] The following is a detailed description of the structure of the outer plate:

[0156] like Figure 13-14 As shown, a first connection structure connected to the supporting device is provided on the outer plate 16. The outer plate body is a plate-like structure provided outside the side plate of the inner liner 11, and the plate-like structure shields the side plate of the inner liner 11 to achieve the effect that the side plate of the inner liner 11 is not exposed and beautiful. Fig.13 The outer plate 16 is the outer plate body. The outer plate 16 is provided with a first connection structure and fixedly connected to the support device, so that the outer plate 16 is firmly connected to the support device, preventing the outer plate 16 from falling due to loose connection, and preventing the outer plate 16 from vibrating and generating noise during the operation of the dishwasher, thereby improving the user experience.

[0157] Specifically, the first connection structure includes a connection arm 161 formed by bending the bottom end of the outer plate 16, and a connection portion is provided on the connection arm 161. The outer plate 16 has a connection surface connected to the support device, and the connection arm 161 can also play a positioning role when the support device is connected and assembled with the outer plate 16, thereby accelerating the connection and assembly efficiency of the outer plate 16 and the support device. The connection arm is integrally extended or spaced along the length direction of the bottom end of the plate-like structure.

[0158] The connecting arm 161 is formed by bending the bottom end of the outer plate 16 toward the side opposite to the outer plate 16. The bottom end of the outer plate 16 is bent toward the side opposite to the outer plate 16 to form the connecting arm 161, so that the connection position between the outer plate 16 and the supporting device is not exposed, and the aesthetics of the inner tank of the dishwasher is not affected.

[0159] Alternatively, the connecting arm 161 is formed by bending the bottom end of the outer plate 16 toward the side away from the inner container. The bottom end of the outer plate 16 is bent toward the side away from the inner container to form the connecting arm 161, and the connecting arm 161 is located at the side of the outer plate 16 away from the inner container instead of being located between the inner container and the outer plate 16, thereby increasing the assembly connection space, making it more convenient to assemble and connect the outer plate 16 and the supporting device, and accelerating the assembly efficiency.

[0160] The outer plate 16 and the support device are fixedly connected by a snap-fit ​​structure, and 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 by a snap-fit ​​structure, and no additional connecting parts are required, which saves costs and speeds up the connection and assembly efficiency.

[0161] 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.

[0162] Alternatively, the outer plate 16 is fixedly connected to the support device through a connecting member, and the connecting portion is a connecting hole provided on the connecting arm 161 for inserting the connecting member. The connecting member is a screw, and the screw passes through the connecting hole provided on the connecting arm 161 to fasten the support device and the outer plate 16. The screw is easy to purchase as a standard part, and there is no need to redesign a new connection structure. It only needs to open a connection hole on the connecting arm 161. The connection process is mature and reliable.

[0163] 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 is conducive to the assembly positioning connection between the supporting device and the outer plate 16 body, and accelerates the assembly connection efficiency.

[0164] As another implementation of this embodiment, as shown in FIG. 13 , 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 via the limiting groove.

[0165] The limiting groove is extended along the direction of the dishwasher being pulled out on the outer plate 16, and a first limiting portion is provided on the groove wall of the limiting groove close to the groove opening of the limiting groove. The limiting groove is extended along the direction of the dishwasher being pulled out on the outer plate 16, and a first limiting portion is provided on the groove wall of the limiting groove close to the groove opening of the limiting groove, so that the connecting portion of the supporting device assembled and connected with the limiting groove can slide into the limiting groove from one end of the limiting groove, and the first limiting portion provided on the groove wall of the groove opening of the limiting groove restricts the connecting portion of the supporting device from moving out of the upper groove opening of the limiting groove.

[0166] Specifically, the first limiting portion is a limiting boss extending along the length direction of the limiting groove. Preferably, the limiting boss is integrally extended or spaced along the length direction of the limiting groove. The limiting boss is integrally injection-molded on the groove wall of the limiting groove. The limiting boss is integrally extended along the length direction of the limiting groove, which makes it easy to form and manufacture. The limiting boss is spaced along the length direction of the limiting groove, which saves the manufacturing material of the limiting boss and makes it easier to assemble the limiting groove and the supporting device.

[0167] The limiting groove is also provided with a second limiting portion, which is a limiting wall provided at one end of the limiting groove in the length direction. The second limiting portion is provided so that the connecting portion of the supporting device will not move out from one end of the limiting groove in the length direction.

[0168] Specifically, the limiting wall and the limiting groove are formed in one piece, that is, one end of the limiting groove in the length direction is provided with an opening for the connecting part of the supporting device to be installed, and the other end is closed.

[0169] A connecting portion is provided on the limiting groove or the outer plate 16. The connection portion enables the lower portion of the outer plate 16 and the supporting device to be fixedly assembled in the limiting groove.

[0170] The connection part is a clamping column or a clamping hole arranged at the end of the limiting groove away from the limiting wall. The connection part of the support device slides into the limiting groove until it abuts against the limiting wall, and the clamping column or the clamping hole arranged at the end of the limiting groove away from the limiting wall is clamped and fixed relative to the connection part of the support device, so that the support device is firmly connected to the outer plate 16.

[0171] Alternatively, the limiting groove is extended along the pulling direction of the dishwasher on the outer plate 16, and a connecting portion is provided in the limiting groove. The connecting portion of the supporting device is firmly fixed to the limiting groove by the setting of the connecting portion, so that the lower part of the outer plate 16 is firmly connected to the supporting device, and the outer plate 16 is prevented from falling due to loose installation.

[0172] Specifically, the outer plate 16 is fixedly connected to the support device through a clamping structure, and the connecting portion is a clamping boss or a clamping hole arranged on the groove wall of the limiting groove. The outer plate 16 and the support device are fixedly connected through the clamping structure, and no additional connecting parts are required, which saves costs and speeds up the connection and assembly efficiency.

[0173] Furthermore, the clamping boss or the clamping hole is integrally extended and arranged on the groove wall of the limiting groove along the pulling direction of the dishwasher; or the clamping boss or the clamping hole is arranged at intervals on the connecting arm along 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 opened 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 at intervals along the length direction of the limiting groove, which saves the manufacturing material of the clamping boss and makes the assembly of the limiting groove and the supporting device easier.

[0174] As another implementation of this embodiment, the outer plate 16 is fixedly connected to the support device through a connecting member, and the connecting portion is a connecting hole provided on the groove wall of the limiting groove for passing the connecting member. The connecting member is a screw, and the screw passes through the connecting hole provided on the wall of the limiting groove to fasten the support device and the outer plate 16. Screws are easy to purchase as standard parts, and there is no need to redesign a new connection structure. It is only necessary to open a connecting hole on the groove wall of the limiting groove. The connection process is mature and reliable.

[0175] The limiting groove is formed by bending the lower end of the outer plate 16 in one piece; the connection strength between the limiting groove and the outer plate 16 is relatively large, so that the connection between the outer plate 16 and the limiting groove is more secure.

[0176] 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 inner tank of the dishwasher will not be affected.

[0177] 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, and the limiting groove is located on the side of the outer plate 16 body away from the inner container instead of between the inner container and the outer plate 16, thereby increasing the assembly connection space, making it more convenient to assemble and connect the outer plate 16 and the supporting device, and accelerating the assembly efficiency.

[0178] Alternatively, the connection portion is a connection hole provided on the outer plate 16 or the groove wall of the limiting groove for inserting a connection member. The connection member may be a standard part such as a bolt or a screw, or the connection member is a buckle, and the connection hole is a buckle installation hole provided on the outer plate 16 or the groove wall of the limiting groove, and the buckle is inserted through the buckle installation hole to fix the outer plate 16 and the support device. The buckle installation hole is located at the fourth buckle installation hole 162.

[0179] Furthermore, a slide rail is provided along the draw-out direction of the dishwasher, and a limiting structure is provided at one end of the slide rail near the door of the dishwasher, and an avoidance notch 164 for avoiding the limiting structure is provided at one end of the outer plate 16 near the limiting structure. The setting of the avoidance notch 164 not only plays a role in avoiding the limiting structure at the end of the slide rail, but also the end of the avoidance notch 164 also plays a role in cooperating with the limiting structure provided at the end of the slide rail.

[0180] like Fig.15 As shown, the upper end of the outer plate 16 is provided with a second connection structure, and the second connection structure is connected to the sealing frame 14 provided at the opening of the inner tank. That is, the upper end of the outer plate 16 is connected to the opening of the inner tank through the sealing frame provided at the opening of the inner tank. By providing a first connection structure at the lower part of the outer plate 16 to be fixedly connected with the support device, and providing a second connection structure at the upper part of the outer plate 16 to be fixedly connected with the sealing frame 14 provided at the top opening of the inner tank, the outer plate 16 is further stably provided on the outer side of the inner tank, so that the outer 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 but the other end is not fixed.

[0181] Specifically, the upper part of the outer plate 16 is plugged and fixedly connected with the sealing frame 14, and the second connection structure includes a plug-in portion and a positioning portion, and the positioning portion is arranged at the bottom end of the plug-in portion. The upper part of the outer plate 16 is plugged and connected with the sealing frame, and no additional connector is required, so the assembly efficiency is high. The positioning portion plays a role in assembly positioning, so that the installer can quickly know that the outer plate 16 and the sealing frame 14 are plugged in place, reducing the installation time.

[0182] Further, the plug-in portion and / or the positioning portion are integrally extended or spaced on the upper portion of the outer plate 16 along the direction of pulling out the dishwasher. The plug-in portion and / or the positioning portion are integrally extended on the upper portion of the outer plate 16 along the direction of pulling out the dishwasher, which is convenient for processing and molding. The plug-in portion and / or the positioning portion are spaced on the upper portion of the outer plate 16 along the direction of pulling out the dishwasher, which reduces the difficulty of plug-in connection, and the upper portion of the outer plate 16 and the sealing frame 14 are easier to assemble.

[0183] The upper end of the outer plate 16 is bent toward the outer side of the inner pot to form a first bending portion, the free end of the first bending portion is bent horizontally toward the inner side of the inner pot to form a horizontal bending portion, and the free end of the horizontal bending portion is bent vertically upward to form a vertical bending portion; the horizontal bending portion is a positioning portion, and the vertical bending portion is a plug-in portion; preferably, the first bending portion is an arc-shaped bend. The plug-in portion and the positioning portion are integrally bent and formed at the upper part of the side wall body, which increases the connection strength between the plug-in portion and / or the positioning portion and the outer plate 16. The setting of the first bending portion allows the outer plate 16 to approach the inner pot, so that the outer plate 16 is closer to the inner pot, reducing the space occupied by the outer plate 16 and increasing the internal space of the inner pot.

[0184] As an implementation of this embodiment, the drawer dishwasher is provided with a photoelectric detection device for detecting whether the door of the drawer dishwasher is opened or closed, and the outer plate 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, thereby preventing the user from forgetting to close the dishwasher door or the dishwasher door from being improperly closed, and further preventing the washing water from splashing out of the door when the dishwasher is working due to the inadequate closure of the dishwasher door, thereby preventing the user from having an 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.

[0185] The following is a detailed description of the assembly relationship between the support device and the outer side plate.

[0186] Combination Figure 1 and Figure 2The outer plates are arranged on two opposite sides of the inner container, and the support device is connected to the outer plates. Since the support device 13 includes a first support device and a second support device, the outer plates 16 also include a first outer plate arranged on one side of the first support device and a second outer plate arranged on one side of the second support device, and the two outer plates are symmetrically arranged.

[0187] 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 which is positioned and connected to the outer plate, and the outer plate has an outer plate positioning matching portion which is positioned and connected to the support device.

[0188] like Figure 5 As shown, the outer plate positioning portion 1342 includes a vertical bottom edge arranged 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 arranged at the bottom, such as Fig.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.

[0189] Another embodiment is as follows: Fig.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, and the position matching structure of the outer plate at least includes a folded edge arranged at the bottom and bent toward the support device, and the folded edge is arranged above the positioning platform.

[0190] 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.

[0191] like Figure 1 As shown, the inner liner assembly also includes a sealing frame 14 at the top of the inner liner, and the sealing frame 14 can also limit the outer plate to a certain extent. On one side of the sealing frame, there is a blocking edge 141 facing the outer plate, which can limit the outer plate. The bottom of the outer plate is positioned with the supporting device, and the top is matched with the sealing frame.

[0192] like Fig.13As shown, the outer panel 16 and the support device 13 have mounting holes corresponding to the positions, and the mounting holes are aligned and then fasteners are inserted to fix the connection. This structure can be set together with the door body assembly structure, and a fourth snap-fit ​​mounting hole 162 corresponding to the first snap-fit ​​mounting hole 13311 is set on the outer panel. The outer panel, the support device and the door body can be fixedly connected together by snap-fit, which reduces the setting of fasteners and facilitates assembly. Alternatively, the fastener is a screw, and the mounting hole is a screw hole. At least one screw hole is set at the corresponding position of the support device and the outer panel, and multiple screw holes can also be set to facilitate the fixation of the structure.

[0193] Since there are many installation structures on the support device, some installation structures need to be covered to prevent the unsightly appearance caused by the exposed structure, but some structures or functions cannot be covered and need to be avoided. The outer plate has a avoidance structure. Fig.13 As shown, the supporting device is provided with a light guide column installation position, and the outer plate has an avoidance hole for avoiding the light path; the outer plate 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 body, so that the position of the door body is detected by reflection.

[0194] 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 connecting part is provided at the bottom of the support device and is fixedly connected to the slide rail, and the outer panel covers the slide rail connecting part and part of the slide rail from the side.

[0195] 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 reliably, and the plate at the limiting notch is thin and is not sufficient to abut against the limiting protrusion.

[0196] The outer plate is square as a whole, and the length / width of the outer plate is not less than the corresponding length / width of the supporting device, so as to be able to shield the structure of the supporting device; the supporting device has a smooth mating surface facing the outer plate, and the outer plate fits tightly on the mating surface and completely covers the mating surface.

[0197] 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, which reduces the setting of installation parts, saves costs, and reduces assembly steps.

[0198] Embodiment 5

[0199] This embodiment mainly introduces in detail the specific structure of the light guide column assembly structure in which the supporting device and the light guide column cooperate.

[0200] 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 arranged on the support body, which is used to install the light guide column to realize the detection of the door position.

[0201] 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 longitudinally arranged on the longitudinal plate.

[0202] Combination Fig.10 , Fig.12 and Fig.16 As shown, the light guide column mounting hole includes a first mounting hole 13312 and a second mounting hole 13313 which are arranged opposite to each other and horizontally spaced a certain distance apart. The two mounting holes which are spaced apart can realize a more stable mounting and fixing of the light guide column.

[0203] Further, such as Fig.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.

[0204] Preferably, combined Fig.10 and Fig.16 As shown, a third longitudinal plate 1361 vertically connected to the first longitudinal plate 1331 is arranged above the support column, the second longitudinal plate includes an upper longitudinal plate 1362 arranged on the upper part of the third longitudinal plate, and the second mounting hole 13313 is arranged on the upper longitudinal plate 1362.

[0205] Specifically, Fig.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 slotted hole correspondingly opened on the upper longitudinal plate 1362 .

[0206] Preferably, Fig.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.

[0207] 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.

[0208] Through the light guide column installation position set on the supporting body, the first light guide column installation position is used to install the first light guide column for light injection, and the second light guide column installation position is used to install the second light guide column for light emission. The light path is emitted from the first light guide column, and a reflective element is correspondingly arranged on the box body. The light path is refracted back to the second light guide column through the reflective element, thereby realizing the detection of whether the door body is closed in place. If it is detected that the light path can be refracted back to the second light guide column, then it can be judged that the door body is closed in place.

[0209] Embodiment 6

[0210] This embodiment will introduce in detail the specific structure of the inner liner of the present invention and how the inner liner is made.

[0211] like Figure 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 a 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.

[0212] 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 achieving capacity expansion of the inner liner.

[0213] Preferably, the inner pot 11 is slidably disposed 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.

[0214] In the above solution, the two side panels are relatively arranged as outward convex structures, 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.

[0215] Preferably, the inner liner includes a front plate and a rear plate respectively connected to two 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 liner.

[0216] In the above scheme, the configuration of the side panel is obtained by stamping a large area in the middle of the side panel, forming a structure with a convex middle and a retracted peripheral side, thereby increasing the internal space of the liner. Specifically, the side panel is stamped with an outer convex molding 114 in the opposite direction to the opposite side panel, forming a shell structure in which the side panel is formed into a bottom wall convex and the peripheral wall extends to one side of the opposite side panel. In this method, a large area of ​​stamping is performed in the middle of the side panel, thereby increasing the internal space of the liner.

[0217] Alternatively, the side panel is configured such that the lower edge of the side panel is bent and recessed 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 supporting device, and the convex structure at the upper portion increases the internal space of the inner tank.

[0218] Preferably, the side panels are respectively provided with first extension surfaces bent toward the front panel and the rear panel to connect the front panel and the rear panel respectively along the sliding direction of the inner container, and the middle portion of the side panels is a plane structure, and the two sides of the plane structure are respectively smoothly connected to the first extension surfaces of the corresponding sides through the first curved surface. The middle portion of the side panels is stamped to form a convex plane, and the curved surface of the plane transitions to the side edge of the side panels, so that the stamping strength of the side panels is small, the inner container manufactured has high strength and good quality, and the inner container with smooth transition has 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 panel and the front and rear panels.

[0219] The middle part of the side panel is a plane, and the plane transitions to the edge of the side panel through a smooth first arc surface on both sides along the sliding direction of the inner liner. The arc surface of the plane in the middle of the side panel transitions to the side edge of the side panel, so that the stamping strength of the side panel is small, the inner liner is high in strength and good in quality, and the inner liner with smooth transition has a good overall gloss and beautiful appearance.

[0220] In this embodiment, the inner container is a drawer structure, and the inner container includes a front plate and a rear plate connected to the two ends of two side plates, and the two sides of the side plates are respectively provided with first extension surfaces that bend and extend toward the front plate and the rear plate, and the first extension surfaces are connected to the corresponding front plate / rear plate, and the bottom wall of the inner container is connected and transitioned to the first extension surface through the smooth first arc surface. Through the design on the first extension surface, the joint position is transferred from the corner between the side plate and the front and rear plates to the plane where the front plate or the rear plate is located, which facilitates and simplifies the connection between the side plate and the front and rear plates.

[0221] See also Fig.19 As shown, in one solution, after the side panel is stamped and formed 114, a concave surface 115 that is concave toward the inner tank is formed at the bottom of the side panel, and the concave surface 115 is used to avoid the slide rail or support device of the dishwasher.

[0222] In the above solution, the inner tank is formed with a concave surface for avoiding the slide rail or the supporting device of the dishwasher, thereby making full use of the space in the dishwasher shell and facilitating the expansion of the inner tank.

[0223] Preferably, the recessed surface 115 includes a recessed surface that gradually indents into the inner liner from top to bottom and a vertical surface that extends downward from the end of the recessed surface. The cross-sectional profile of the recessed surface through the vertical surface perpendicular to the side plate 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 edge of the convex profile, or the two bends of the recessed surface 115, has 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.

[0224] See also Fig.18 As shown in FIG. 1 , in another structure, the concave surface is a concave surface directly punched from the bottom of the side plate toward the inner part of the inner container, and the concave surface includes a horizontal bending surface 1151 formed by bending the bottom wall of the side plate from top to bottom toward the inner part of the inner container, and a vertical bending surface 1152 formed by bending the end of the horizontal bending surface 1151 vertically downward, and the horizontal bending surface and the vertical bending surface are connected and transitioned by a smooth arc surface. Fig.19 The structure is different. Fig.19 In the middle, the concave surface is indirectly formed by the convex pressing of the stamping. Because the pressing profile is large, the stamping strength cannot be high, so it has no horizontal bending surface. Fig.16 Because it is a directly stamped concave surface, the stamping area is small, and a concave surface with a horizontal bending surface and a vertical bending surface can be stamped out. The support device is provided with a slide rail mounting portion, and the slide rail mounting portion is a slide rail mounting groove extending along the length direction of the slide rail, and the concave 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 bending surface, and the slide rail mounting groove side plates are arranged parallel to the vertical bending surface.

[0225] Furthermore, an avoidance step is provided at the upper end of the side plate of the slide rail installation groove on the side close to the inner container, and the avoidance step extends along the length direction of the slide rail installation groove, and the avoidance step is a recessed step formed by the upper end of the side plate of the slide rail installation groove being recessed toward the side away from the inner container. Specifically, the recessed step includes a first bent portion formed by bending the upper end of the side plate of the slide rail installation groove toward the side away from the inner container, and the free end of the first bent portion is bent upward to form a second bent portion; the free end of the second bent portion is connected to the top plate of the slide rail installation groove.

[0226] Preferably, the bottom edge of the side plate is provided with a second extension surface that bends and extends toward the bottom plate, and the concave surface and the second extension surface are smoothly transitioned. The second extension surface is connected to the bottom plate of the inner container.

[0227] Furthermore, the front plate and / or the rear plate of the inner tank are similar to the two side plates, and are configured to be convex to the outside of the inner tank, thereby achieving the expansion of the inner tank. Its structure can be similar to the above two side plates, and the concave surface at the bottom of the rear plate can avoid the rear water channel. I will not repeat it here.

[0228] As an implementation method of this embodiment, Fig.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.

[0229] 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 pulling direction of the dishwasher.

[0230] The second splicing component / the third splicing component includes a side panel 111 parallel to the pulling direction of the dishwasher, and the second splicing component / the third splicing component also includes an extension portion connected to the side panel 111 and bent toward the opposite side panel, and the extension portion is connected to the first splicing component, and the extension portion includes a rounded corner structure between the inner tank wall surfaces. The setting of the extension portion makes the splicing position of the second splicing component / the third splicing component and the first splicing component located on a plane.

[0231] The second splicing component / the third splicing component is formed by stamping as one piece, 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.

[0232] The side plate 111 of the second splicing component / the third splicing component includes a recessed surface 115, which is a receiving portion recessed toward the center of the inner tank. The receiving portion can be used to avoid the slide rail or the supporting device, so as to facilitate the inner tank to be pushed into or pulled out of the dishwasher body and to take and place the tableware in the dishwasher.

[0233] Same as the previous implementation method, Fig.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.

[0234] 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.

[0235] Preferably, in this embodiment, a first extension surface 1111 that is bent and extended 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 .

[0236] 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.

[0237] Preferably, second extension surfaces 1112 that are bent and extended 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 the rear plate 113 .

[0238] 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.

[0239] 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 the plane, thereby simplifying the welding process.

[0240] 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.

[0241] 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.

[0242] 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, and 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, and the first connecting surface is a U-shape 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, extends toward the opposite side splicing component, and then bends upward to form a second connecting surface, and the second connecting surface is a U-shape with an opening facing opposite to the first connecting surface, and the first connecting surface and the second connecting surface are nested and connected.

[0243] like Fig. 20 As shown, a sealing frame 14 is also provided at the top opening of the inner tank 11, and a mounting groove for assembling the top opening of the inner tank is provided at the bottom of the sealing frame 14 near the inner tank. A water retaining structure 117 is provided on the side wall of the inner tank 11 to prevent water from entering the gap between the sealing frame 14 and the wall surface of the inner tank 11. The provision of the water retaining structure 117 can effectively prevent washing water from entering the gap between the sealing frame 14 and the wall surface of the inner tank 11 and flushing the sealing structure, thereby extending the service life of the sealing structure and improving the overall user experience of the product.

[0244] In order to avoid friction and noise generated 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 .

[0245] like Fig. 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. An accommodating portion is provided on the groove wall of the mounting groove of the sealing frame 14, and the water retaining structure 117 is snap-connected with the accommodating portion. The accommodating portion is a groove whose groove wall of the mounting groove 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, increases the compactness of the sealing structure, and improves the compactness of the assembly between the sealing frame 14 and the inner tank 11, while improving the safety of the dishwasher.

[0246] The water retaining structure may also be located at the lower edge of the sealing frame. The water retaining structure is a convex structure sunken toward the center of the inner container. The convex structure is located at the lower edge of the sealing frame.

[0247] The part where the top surface of the inner liner 11 cooperates with the sealing frame 14 is provided with a folding structure 116 facing 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 toward the outside of the inner liner. A through hole 143 is provided on the groove wall opposite to the mounting groove of the sealing frame 14 and the accommodating portion. The lower surface of the through hole 143 is longer than the upper surface, and the lower surface protrudes toward the direction close to 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, use a tool smaller than the diameter of the through hole 143 to enter the through hole 143 from the side away from the wall of the inner liner, and push the end of the folding structure 1117 away from the lower surface of the through hole 143. The operation is simple, which brings a good user experience.

[0248] As a further limitation of this embodiment, the folding structure 116 located on the top surface of the inner liner 11 is extended as a whole or arranged at intervals, and the through holes 143 located on the sealing frame 14 correspond one-to-one to the folding structure 116 and cooperate with each other, which is beneficial to the demoulding of the sealing frame 14 and enhances the compactness of the seal.

[0249] As another implementation of this embodiment, a limiting boss is provided on the groove wall of the installation groove of the sealing frame 14 on the side 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 extended or spaced. In this embodiment, the inner liner 11 includes four side panels with straight top surfaces, and the side panels are connected by rounded transition side panels, and the water retaining structure 117 is located at the upper part of the side panels.

[0250] The sealing frame 14 can also be integrally injection-molded onto the top of the inner container to increase the connection strength between the inner container and the sealing frame.

[0251] The bottom of the sealing frame 14 is provided with a plug-in slot for installing the upper end of the outer plate on one side away from the inner container. The plug-in slot is plugged and fixedly assembled with the plug-in portion on the upper end of the outer plate to fix the upper part of the outer plate. The plug-in slot is integrally extended or spaced along the length direction of the bottom of the sealing frame, and the plug-in slot and the plug-in arm are arranged one by one.
