Description

Technical Field

[0001] The utility model relates to the field of dishwashers, in particular to an inner container structure of a dishwasher and a dishwasher using the same. Background Art

[0002] A dishwasher is an automated device used for cleaning and drying tableware, kitchen utensils, and other dining utensils. It can help reduce the time and labor of hand-washing tableware while ensuring cleanliness and hygiene.

[0003] The inner container of a dishwasher is a cavity inside the dishwasher for placing tableware and cleaning utensils. It generally consists of a top plate, a middle plate, and a bottom plate. Among them, the middle plate is a plate-shaped structure bent into a U shape, used to connect the top plate above and the bottom plate below, so as to form a cavity structure with an open front end. It can be seen that the height of the inner container of the dishwasher is determined by the width of the middle plate.

[0004] During the production process of the inner container of the dishwasher, the required sheet materials are provided by suppliers. Since the height specifications of conventional inner containers of dishwashers are fixed, the width of the middle plates mass-produced by suppliers is generally also fixed. If it is necessary to produce an inner container of a dishwasher with a height higher than the conventional height, it is necessary to find a supplier to customize a middle plate with a larger width. However, in the case of a small demand, affected by the scale effect, finding a supplier to customize a sheet material with a larger size will undoubtedly greatly increase the production cost.

[0005] Based on this, the utility model provides an inner container structure of a dishwasher and a dishwasher using the same. By improving the inner container structure, the purpose of producing an inner container with a higher height using sheet materials of the existing width is achieved, thereby greatly reducing the production cost. At the same time, a dishwasher using the inner container of the utility model can also have a higher height, so that the floor area can be reduced without changing the capacity of the dishwasher, and the usage cost of the site can be reduced. Summary of the Utility Model

[0006] Based on this, it is necessary to provide an inner container structure of a dishwasher, including a top plate, a middle plate, and a bottom plate connected in sequence from top to bottom. The middle plate is composed of a back plate, a left side plate, and a right side plate. Among them, the rear ends of the left side plate and the right side plate are respectively fixedly connected to the left and right ends of the back plate, and both the left side plate and the right side plate are perpendicular to the back plate.

[0007] In the utility model, the inner container structure is installed and used in a dishwasher for placing tableware, cleaning utensils, etc.

[0008] In the present utility model, the middle plate adopts a split structure, which is formed by splicing a back plate and left and right side plates on both sides of the back plate. Compared with the middle plate structure integrally formed by a single piece of plate material at present, the widths of the back plate, the left side plate and the right side plate of the present utility model are much smaller than the width of the middle plate. Therefore, in the production process, different from using the length direction of the plate material as the width direction of the middle plate at present, the present utility model can use the width direction of the plate material as the width direction of the back plate, the left side plate and the right side plate, and use the length direction of the plate as the height direction of the back plate, the left side plate and the right side plate. And since there is no limit to the length in the length direction during the production process of the plate material, the present utility model can select plate materials of existing sizes for the production of the middle plate, and can produce middle plates with a relatively high height. Among them, if the width dimension of the existing plate material is larger than the widths of the back plate, the left side plate and the right side plate, only a certain amount of cutting of the existing-sized plate material is required during the production process.

[0009] It can be seen that by improving the structure of the middle plate and changing the middle plate into a split structure composed of a back plate, a left side plate and a right side plate, the present utility model can reduce the requirement for the width dimension of the plate material for the middle plate, so that the inner tank structure with a relatively high height can be produced using the existing-sized plate material, achieving the purpose of reducing production costs.

[0010] Furthermore, the left and right ends of the back plate are respectively bent backward to form first rear side edges perpendicular to the back plate, and a plurality of first mounting holes are provided in the first rear side edges; the rear ends of the left side plate and the right side plate are respectively attached to the first rear side edges on the left and right sides of the back plate, and second mounting holes are provided corresponding to the first mounting holes, and the left side plate and the right side plate are fixedly connected to the back plate through a bolt connection structure that simultaneously passes through the first mounting holes and the second mounting holes.

[0011] In the present utility model, the first rear side edges on the back plate serve as the mounting structures for the left side plate and the right side plate, which can facilitate the installation of the left side plate and the right side plate on the back plate. Specifically, the rear edge ends of the left side plate and the right side plate are mutually attached to the first rear side edges of the back plate and are fixedly connected to each other through a bolt connection structure. In this way, on the premise of ensuring the strength of the connection structure between the left side plate, the right side plate and the back plate, inside the inner tank structure, the junctions between the left side plate, the right side plate and the back plate can be closely abutted and have a smooth transition, which is convenient for the application of sealant.

[0012] Further, the upper and lower ends of the back plate are bent backward respectively to form a second rear side edge perpendicular to the back plate, the upper and lower ends of the left side plate are bent leftward respectively to form a left side edge perpendicular to the left side plate, and the upper and lower ends of the right side plate are bent rightward respectively to form a right side edge perpendicular to the right side plate; wherein, the second rear side edge, the left side baffle and the right side baffle located at the upper and lower ends of the back plate, the left side plate and the right side plate are respectively located on the same horizontal plane to form a first installation edge and a second installation edge.

[0013] In the present utility model, the second rear side edge, the left side baffle and the right side baffle formed by bending the upper and lower ends of the back plate, the left side plate and the right side plate that are assembled into the middle plate respectively form a planar first installation edge and a second installation edge at the upper and lower ends of the middle plate. Among them, the planar first installation edge and the second installation edge can facilitate the fitting of the middle plate with the top plate and the chassis, so as to facilitate the mutual connection of the middle plate with the top plate and the chassis.

[0014] Further, a plurality of third installation holes are formed in the first installation edge, the edge of the top plate is attached to the first installation edge, and a plurality of fifth installation holes are formed in the top plate corresponding to the third installation holes. The top plate is fixedly connected to the first installation edge through a bolt connection structure that simultaneously passes through the third installation holes and the fifth installation holes; a plurality of fourth installation holes are formed in the second installation edge, the edge of the chassis is attached to the second installation edge, and a plurality of sixth installation holes are formed in the chassis corresponding to the fourth installation holes. The chassis is fixedly connected to the second installation edge through a bolt connection structure that simultaneously passes through the fourth installation holes and the sixth installation holes.

[0015] In the present utility model, the top plate is attached to the first installation edge of the middle plate and is fixedly connected to the first installation edge through a bolt connection structure. The chassis is attached to the second installation plate of the middle plate and is fixedly connected to the second installation edge through a bolt connection structure. As described in the foregoing records about the connection structure of the back plate, the left side plate and the right side plate, such a structure can, on the premise of ensuring the strength of the connection structure between the top plate and the chassis and the middle plate, also make the junction between the top plate and the chassis and the middle plate in the inner liner structure closely abut and have a smooth transition inside the inner liner structure, which can facilitate the coating of the sealant.

[0016] Further, the part of the top plate that fits the first installation edge and the first installation edge are assembled to form a first support flange, and the part of the chassis that fits the second installation edge and the second installation edge are assembled to form a second support flange.

[0017] In the present utility model, the first support flange and the second support flange formed by the top plate and the bottom plate being joined with the first mounting edge and the second mounting edge protrude from the outer surface of the inner container structure, and can be used as the mounting structure of the inner container structure in the dishwasher. Compared with the smooth outer surface of the inner container structure, it is convenient to install the inner container structure in the dishwasher.

[0018] Further, it further includes a bracket. The bracket includes at least two left support columns, at least two right support columns, a top frame fixedly connecting the tops of the left support columns and the right support columns, and a bottom frame fixedly connecting the tops of the left support columns and the right support columns. Among them, the left support columns are located on the left side of the left plate, the right support columns are located on the right side of the right plate. First slots and second slots are respectively formed on the right sides of the left support columns corresponding to the first support flange and the second support flange, and the first support flange and the second support flange are respectively embedded in the first slot and the second slot. Third slots and fourth slots are formed on the left side of the right support columns corresponding to the first support flange and the second support flange, and the first support flange and the second support flange are embedded in the third slot and the fourth slot.

[0019] In the present utility model, the bracket needs to be fixedly installed in the dishwasher for use in the installation of the inner container structure. Among them, the first slots, second slots, third slots, and fourth slots provided on the left support columns and the right support columns of the bracket are used for the embedding of the first support flange and the second support flange, which can play a role in supporting the inner container structure and play a positioning role during the installation process of the inner container structure, and can greatly facilitate the installation of the inner container structure on the bracket.

[0020] Further, the parts of the left plate and the right plate that are in contact with the first rear side edge are respectively joined with the first rear side edge to form a first fixing flange and a second fixing flange. A plurality of seventh mounting holes are formed on the first fixing flange, and a plurality of eighth mounting holes are formed on the second fixing flange. One side wall of one of the left support columns is arranged in contact with the first fixing flange, and a ninth mounting hole is formed corresponding to the seventh mounting hole, and is fixedly connected to the first fixing flange through a bolt connection structure that simultaneously passes through the seventh mounting hole and the ninth mounting hole. One side wall of one of the right support columns is arranged in contact with the second fixing flange, and a tenth mounting hole is formed corresponding to the eighth mounting hole, and is fixedly connected to the first fixing flange through a bolt connection structure that simultaneously passes through the eighth mounting hole and the tenth mounting hole.

[0021] In the present utility model, the first rear side edge formed on the back plate, in addition to serving as the installation structure for the left side plate and the right side plate and being fixedly connected to the left side plate and the right side plate, at the same time, can also serve as a connection structure to form a first fixed flange and a second fixed flange with the rear end edges of the left side plate and the rear side plate for fixedly connecting to the bracket, which can play a role in strengthening the strength and stability of the connection structure between the bracket and the inner tank structure.

[0022] On the other hand, the present utility model also provides a dishwasher using the above inner tank structure.

[0023] In the present utility model, the dishwasher using the above inner tank has a higher height compared with a conventional dishwasher, so that the floor area of the dishwasher can be reduced without changing the capacity of the dishwasher, which is convenient for placing the dishwasher and reduces the usage cost of the site.

[0024] The principle and effect of the present utility model will be further described below in conjunction with the above technical solutions and the accompanying drawings:

[0025] By improving the structure of the middle plate, the present utility model improves the middle plate into a split structure composed of a back plate, a left side plate and a right side plate, which can reduce the requirement of the middle plate for the width dimension of the plate material, so that the inner tank structure with a higher height can be produced using the existing size of the plate material, achieving the purpose of reducing the production cost.

[0039] For the convenience of those skilled in the art to understand, the present utility model will be further described in detail below in conjunction with the drawings and embodiments:

[0040] As Figure 1-11 , a dishwasher inner tank structure includes a top plate 1, a middle plate and a chassis 3 connected in sequence from top to bottom. The middle plate is formed by splicing a back plate 21, a left side plate 22 and a right side plate 23. Among them, the rear ends of the left side plate 22 and the right side plate 23 are respectively fixedly connected to the left and right ends of the back plate 21, and the left side plate 22 and the right side plate 23 are both perpendicular to the back plate 21.

[0041] In the present utility model, the inner tank structure is installed and used in a dishwasher for placing tableware, cleaning utensils, etc.

[0042] In the present utility model, the middle plate adopts a split structure, which is formed by splicing a back plate 21 and left and right side plates 22 and 23 on both sides of the back plate 21. Compared with the current middle plate structure integrally formed by a single piece of plate, the widths of the back plate 21, the left side plate 22 and the right side plate 23 of the present utility model are much smaller than the width of the middle plate. Therefore, during the production process, different from using the length direction of the plate material as the width direction of the middle plate at present, the present utility model can use the width direction of the plate material as the width direction of the back plate 21, the left side plate 22 and the right side plate 23, and use the length direction of the plate as the height direction of the back plate 21, the left side plate 22 and the right side plate 23. And since there is no limit to the length in the length direction during the production of the plate, the present utility model can select plates of existing sizes for the production of the middle plate and can produce middle plates with a relatively high height. Among them, if the width dimension of the existing plate is greater than the widths of the back plate 21, the left side plate 22 and the right side plate 23, only a certain amount of cutting of the existing-sized plate is required during the production process.

[0043] It can be seen that by improving the structure of the middle plate, the present utility model improves the middle plate into a split structure composed of a back plate 21, a left side plate 22 and a right side plate 23, which can reduce the requirement for the width dimension of the plate material for the middle plate, so that the inner tank structure with a relatively high height can be produced using the plate material of the existing size, achieving the purpose of reducing the production cost.

[0044] In one embodiment, the left and right ends of the back plate 21 are bent backward respectively to form first rear side edges 211 perpendicular to the back plate 21, and a plurality of first mounting holes are provided on the first rear side edges 211; the rear ends of the left side plate 22 and the right side plate 23 are respectively attached to the first rear side edges 211 on the left and right sides of the back plate 21, and second mounting holes are provided corresponding to the first mounting holes. The left side plate 22 and the right side plate 23 are fixedly connected to the back plate 21 through a bolt connection structure that simultaneously passes through the first mounting holes and the second mounting holes.

[0045] In this embodiment, the first rear side edges 211 on the back plate 21 are used as the mounting structures for the left side plate 22 and the right side plate 23, which can facilitate the installation of the left side plate 22 and the right side plate 23 on the back plate 21. Specifically, the rear end edges of the left side plate 22 and the right side plate 23 are mutually attached to the first rear side edges 211 of the back plate 21 and are fixedly connected to each other through a bolt connection structure. In this way, on the premise of ensuring the strength of the connection structure between the left side plate 22, the right side plate 23 and the back plate 21, inside the inner tank structure, the junctions between the left side plate 22, the right side plate 23 and the back plate 21 can be closely abutted and have a smooth transition, which is convenient for the coating of sealant.

[0046] In one embodiment, the upper and lower ends of the back plate 21 are bent backward respectively to form second rear side edges 212 perpendicular to the back plate 21. The upper and lower ends of the left side plate 22 are bent leftward respectively to form left side edges 221 perpendicular to the left side plate 22. The upper and lower ends of the right side plate 23 are bent rightward respectively to form right side edges 231 perpendicular to the right side plate 23. Among them, the second rear side edges 212, left side edges and right side edges 231 located at the upper and lower ends of the back plate 21, left side plate 22 and right side plate 23 are respectively located on the same horizontal plane to form a first mounting edge and a second mounting edge.

[0047] In this embodiment, the second rear side edges 212, left side edges and right side edges 231 formed by bending the upper and lower ends of the back plate 21, left side plate 22 and right side plate 23 that are joined together to form the middle plate respectively form planar first mounting edge and second mounting edge at the upper and lower ends of the middle plate. Among them, the planar first mounting edge and second mounting edge can facilitate the fitting of the middle plate with the top plate 1 and the chassis 3, so as to facilitate the mutual connection between the middle plate, the top plate 1 and the chassis 3.

[0048] In one embodiment, a plurality of third mounting holes are provided on the first mounting edge. The edge of the top plate 1 is attached to the first mounting edge, and a plurality of fifth mounting holes are provided on the top plate 1 corresponding to the third mounting holes. The top plate 1 is fixedly connected to the first mounting edge through a bolt connection structure that simultaneously passes through the third mounting holes and the fifth mounting holes. A plurality of fourth mounting holes are provided on the second mounting edge. The edge of the chassis 3 is attached to the second mounting edge, and a plurality of sixth mounting holes are provided on the chassis 3 corresponding to the fourth mounting holes. The chassis 3 is fixedly connected to the second mounting edge through a bolt connection structure that simultaneously passes through the fourth mounting holes and the sixth mounting holes.

[0049] In this embodiment, the top plate 1 is attached to the first mounting edge of the middle plate and is fixedly connected to the first mounting edge through a bolt connection structure. The chassis 3 is attached to the second mounting plate of the middle plate and is fixedly connected to the second mounting edge through a bolt connection structure. As described above regarding the connection structure of the back plate 21, left side plate 22 and right side plate 23, such a structure can, on the premise of ensuring the strength of the connection structure between the top plate 1 and the chassis 3 and the middle plate, also enable the junction between the top plate 1 and the chassis 3 and the middle plate to be in close contact and have a smooth transition inside the inner tank structure, which can facilitate the coating of sealant.

[0050] In one embodiment, the part of the top plate 1 that fits the first mounting edge and the first mounting edge are joined together to form a first support flange, and the part of the chassis 3 that fits the second mounting edge and the second mounting edge are joined together to form a second support flange.

[0051] In this embodiment, the top plate 1 and the chassis 3 are joined with the first mounting edge and the second mounting edge to form a first support flange and a second support flange that protrude from the outer surface of the inner tank structure. These can be used as the mounting structure of the inner tank structure inside the dishwasher. Compared with the smooth outer surface of the inner tank structure, it is convenient to install the inner tank structure inside the dishwasher.

[0052] In one embodiment, it further includes a bracket. The bracket includes at least two left support columns 431, at least two right support columns 432, a top frame 41 fixedly connecting the tops of the left support columns 431 and the right support columns 432, and a bottom frame 42 fixedly connecting the tops of the left support columns 431 and the right support columns 432. Among them, the left support columns 431 are located on the left side of the left plate 22, the right support columns 432 are located on the right side of the right plate 23. A first slot and a second slot 4312 are respectively formed on the right side of the left support columns 431 corresponding to the first support flange and the second support flange. The first support flange and the second support flange are respectively embedded in the first slot and the second slot 4312. A third slot 4321 and a fourth slot 4322 are formed on the left side of the right support columns 432 corresponding to the first support flange and the second support flange. The first support flange and the second support flange are embedded in the third slot 4321 and the fourth slot 4322.

[0053] In this embodiment, the bracket needs to be fixedly installed inside the dishwasher for the installation of the inner tank structure. Among them, the first slot, the second slot 4312, the third slot 4321, and the fourth slot 4322 provided on the left support columns 431 and the right support columns 432 of the bracket are used for the embedding of the first support flange and the second support flange, which can play a role in supporting the inner tank structure and positioning it during the installation process of the inner tank structure, and can greatly facilitate the installation of the inner tank structure on the bracket.

[0054] In one embodiment, the parts of the left plate 22 and the right plate 23 that are in contact with the first rear side edge 211 are respectively joined with the first rear side edge 211 to form a first fixing flange and a second fixing flange. A number of seventh mounting holes are formed on the first fixing flange, and a number of eighth mounting holes are formed on the second fixing flange. One side wall of one of the left support columns 431 is arranged in contact with the first fixing flange, and a ninth mounting hole is formed corresponding to the seventh mounting hole, and is fixedly connected to the first fixing flange through a bolt connection structure that simultaneously passes through the seventh mounting hole and the ninth mounting hole. One side wall of one of the right support columns 432 is arranged in contact with the second fixing flange, and a tenth mounting hole is formed corresponding to the eighth mounting hole, and is fixedly connected to the first fixing flange through a bolt connection structure that simultaneously passes through the eighth mounting hole and the tenth mounting hole.

[0055] In this embodiment, the first rear side edge 211 formed on the back plate 21, in addition to serving as the installation structure for the left side plate 22 and the right side plate 23 and being fixedly connected to the left side plate 22 and the right side plate 23, at the same time, can also serve as a connection structure to form a first fixing flange and a second fixing flange with the rear end edges of the left side plate 22 and the rear side plate, for fixedly connecting with the bracket, which can play a role in strengthening the strength and stability of the connection structure between the bracket and the inner tank structure.

[0056] On the other hand, the present utility model also provides a dishwasher using the above inner tank structure.

[0057] In the present utility model, the dishwasher using the above inner tank has a higher height than a conventional dishwasher, so that the floor area of the dishwasher can be reduced without changing the capacity of the dishwasher, which is convenient for placing the dishwasher.

[0058] The above embodiments only express several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
