Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a door structure for a dishwasher and a dishwasher. Background Technology

[0002] In kitchen appliances with doors, such as dishwashers, the door includes a panel-shaped door liner (i.e., the inner door). Near its edge, the door liner has a protrusion that extends from the inner side of the door liner toward the outer side of the door. The protrusion is usually fitted with a latch, which is used to lock or unlock with the locking components on the cabinet as the door is opened and closed.

[0003] For example, the Chinese utility model patent disclosed in patent application number CN202222223449.7 (publication number CN218165234U) entitled "Door Tongue Assembly, Door Body and Dishwasher" includes a door tongue and fasteners; the door tongue is provided with connecting holes through both sides, and the door tongue can abut against the front of the door liner and the connecting holes are connected to the through holes of the door liner.

[0004] However, the area where the door tongue is located on the door liner is subjected to greater force during the opening and closing of the door. If the connection between this area and the outer door is not secure, the door liner may loosen and create gaps after the door has been opened and closed multiple times. This not only affects the appearance, but also allows debris to fall between the door liner and the outer door, which may affect the normal operation of electrical components between the door liner and the outer door. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a door structure for a dishwasher that prevents the inner and outer doors from loosening at the location of the tongue, in light of the current state of the technology.

[0006] The second technical problem to be solved by this utility model is to provide a dishwasher that applies the above-mentioned door structure, in view of the current state of the prior art.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a door structure for a dishwasher, comprising...

[0008] The inner door includes a rearwardly protruding bulge and a plate extending from at least a partial periphery of the bulge in a direction away from the bulge;

[0009] An outer door is located in front of the inner door, and the outer door is attached to the panel and the two are connected by a first connector;

[0010] The locking assembly is located on the top wall of the convex hull;

[0011] The feature is that there are multiple first connectors arranged sequentially at intervals along the circumference of the plate, and one of the first connectors is located directly in front of the locking assembly.

[0012] To facilitate maintenance and replacement of the latch assembly, the latch assembly includes a base on the top wall of the protrusion and a latch bolt on top of the base. The latch bolt is detachably connected to the base, with one of the first connecting members located directly in front of the latch bolt. This separate design of the latch assembly means that the latch bolt is the most easily damaged part; only the latch bolt needs to be replaced, without affecting the inner or outer doors.

[0013] To connect the base and the latch, the base has a protrusion at the top and the latch has a slot at the bottom into which the protrusion can be detachably inserted; or, the base has a slot with an open top and the latch has a protrusion that can be detachably inserted into the slot.

[0014] To minimize the space occupied by the locking assembly, the base is located below the top wall of the convex bulge. The top wall of the convex bulge has a through hole for partial exposure of the base, through which the convex portion can pass. This design utilizes the internal space of the convex bulge, resulting in a streamlined structure with only the latch exposed, occupying a small amount of space.

[0015] To improve the connection between the base and the latch, one method is to detachably bind the slot and the protrusion together via a second connector.

[0016] Because the front of the latch is blocked by the outer door, in order to facilitate the operation of the second connector, one method is to have the second connector constrain the protrusion and the slot together from back to front.

[0017] Because the front of the latch is obstructed by the outer door, another method is used to facilitate the operation of the second connector: the top of the latch has a through hole, and the second connector passes through the through hole from top to bottom, constraining the protrusion and the slot together. In this state, the top of the second connector is hidden in the through hole, and a detachable plug is embedded in the through hole, with the plug located above the second connector. The plug design improves the aesthetics of the latch and prevents debris from falling into the through hole.

[0018] To improve the connection between the base and the latch, another method is as follows: a positioning block is provided on the side wall of the protrusion, and a groove and a positioning platform are provided on the inner wall of the slot. The positioning platform and the groove are arranged adjacent to each other along the circumference of the slot. One end of the groove passes through the slot opening, and the other end connects to the positioning platform. Two positioning parts are spaced apart along the circumference of the slot on the positioning platform. The positioning block can pass through the groove and be limited between the two positioning parts, and the positioning block can pass over the positioning part closer to the groove under external force. During installation, simply insert the positioning block into the groove, and then rotate the latch to limit the positioning block between the two positioning parts; during disassembly, rotate the latch to release the positioning block from the constraint of the two positioning parts, and then pull the latch upward to disengage the protrusion from the slot.

[0019] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows: a dishwasher, characterized in that it includes a front-opening cabinet and the aforementioned door structure, wherein the door structure is movably disposed at the opening of the cabinet to open or close the cabinet, and the cabinet is provided with a locking component that can be detachably constrained with a locking tongue. When the door structure is open, the locking component disengages from the locking tongue, and when the door structure is closed, the locking component locks with the locking tongue.

[0020] Compared with the prior art, the advantages of this utility model are as follows: By setting a first connecting piece in front of the latch assembly, this utility model can ensure the firmness of the connection between the inner and outer doors and the outer door at the latch assembly, and prevent the inner and outer doors from becoming loose and gaps from appearing after many opening and closing of the door. This not only affects the appearance, but also allows debris to enter the gaps. Attached Figure Description

[0036] Example 1

[0037] like Figures 1-6 As shown, the dishwasher of this preferred embodiment includes a cabinet and a door structure. The front of the cabinet is open, and the door structure includes an inner door 1, an outer door 2, and a locking assembly.

[0038] The inner door 1 includes a rearwardly protruding bulge 11 and a plate 12 extending from at least a partial periphery of the bulge 11 in a direction away from the bulge 11. In this embodiment, the plate 12 extends from the top edge, left edge, and right edge of the bulge 11 to form the plate 12.

[0039] The outer door 2 is located in front of the inner door 1. The outer door 2 is attached to the plate 12 and the two are connected by the first connector 7. In this embodiment, the first connector 7 is a screw. Both the plate 12 and the outer door 2 are provided with connecting holes 10 for the screw to pass through and connect.

[0040] The latch assembly is located on the top wall of the protrusion 11. There are multiple first connectors 7 arranged sequentially at intervals along the circumference of the plate 12, with one of the first connectors 7 located directly in front of the latch assembly. This ensures the secure connection between the inner door 1 and the outer door 2 at the latch assembly, preventing them from becoming loose and creating gaps, which would not only affect the aesthetics but also allow debris to enter.

[0041] The latch assembly includes a base 3 disposed on the top wall of the protrusion 11 and a latch 4 disposed on the top of the base 3. The latch 4 is detachably connected to the base 3, and one of the first connecting parts 7 is located directly in front of the latch 4. In this embodiment, the latch assembly is designed as a separate unit. The latch 4 is the most easily damaged part of the latch assembly. Only the latch 4 needs to be replaced, which will not affect the inner door 1, outer door 2, etc. During installation, the base 3 is first installed on the top wall of the protrusion 11 with screws, and then the latch 4 is installed on the base 3.

[0042] To connect the base 3 and the latch 4, in this embodiment, the top of the base 3 is provided with a protrusion 51, and the bottom of the latch 4 is provided with a slot 52 into which the protrusion 51 can be detachably inserted. The base 3 is located below the top wall of the protrusion 11, and the top wall of the protrusion 11 has a through hole 31 for partial exposure of the base 3, through which the protrusion 51 can pass. In this way, the base 3 utilizes the space inside the protrusion 11, resulting in a simplified structure, with only the latch 4 exposed, occupying a small amount of space.

[0043] Furthermore, the slot 52 and the protrusion 51 are detachably bound together by the second connector 6. Because the front of the latch 4 is blocked by the outer door 2, in order to facilitate the operation of the second connector 6, in this embodiment, the second connector 6 binds the protrusion 51 and the slot 52 together from back to front. The second connector 6 is a screw.

[0044] In this embodiment, the base 3 and the latch 4 are first pre-fixed by inserting the slot 52 and the protrusion 51, and then the base 3 and the latch 4 are connected by the second connector 6.

[0045] The door structure is movably located at the opening of the cabinet. Specifically, the inner door 1 and the outer door 2 constitute the door body. The lower part of the door body is rotatably connected to the cabinet body to open or close the cabinet body. The cabinet body is provided with a locking component that can be detachably bound to the latch 4. When the door structure is open, the locking component disengages from the latch 4; when the door structure is closed, the locking component locks to the latch 4. These are all prior art technologies and will not be elaborated here. For example, refer to the Chinese invention patent application "Door Lock and Dishwasher" published by patent application number CN202210994413.0 (publication number CN117627464A).

[0046] Example 2

[0047] like Figure 7 As shown, the connection method of the second connector 6 in Embodiment 2 is different from that in Embodiment 1.

[0048] In this embodiment, the top of the latch 4 is provided with a through hole 41. The second connector 6 passes through the through hole 41 from top to bottom to constrain the protrusion 51 and the slot 52 together. In this state, the top of the second connector 6 is hidden in the through hole 41. A plug 42 is detachably embedded in the through hole 41, and the plug 42 is located above the second connector 6. The design of the plug 42 improves the aesthetics of the latch 4 and can prevent debris from falling into the through hole 41.

[0049] In the above embodiments 1 and 2, the base 3 may be provided with a slot 52 with an open top, and the locking tongue 4 may be provided with a protrusion 51 that can be detachably inserted into the slot 52.

[0050] Example 3

[0051] like Figures 8-10 As shown, the difference between Example 3 and Example 1 is that:

[0052] 1. The base 3 is provided with a slot 52 with an open top, and the locking tongue 4 is provided with a protrusion 51 that can be detachably inserted into the slot 52.

[0053] 2. The protrusion 51 and the slot 52 are not detachably bound together by the second connector 6, but are detachably bound together in the following manner:

[0054] A positioning block 511 is provided on the side wall of the protrusion 51, and a groove 521 and a positioning platform 522 are provided on the inner wall of the slot 52. The positioning platform 522 and the groove 521 are arranged adjacent to each other along the circumference of the slot 52. One end of the groove 521 passes through the opening of the slot 52, and the other end is connected to the positioning platform 522. Two positioning parts 523 are provided on the positioning platform 522 at intervals along the circumference of the slot 52. The positioning block 511 can pass through the groove 521 and be limited between the two positioning parts 523. Under the action of external force, the positioning block 511 can pass over the positioning part 523 near the groove 521. During installation, simply insert the positioning block 511 into the groove 521, and then rotate the locking tongue 4 to limit the positioning block 511 between the two positioning parts 523. During disassembly, rotate the locking tongue 4 to release the positioning block 511 from the constraint of the two positioning parts 523, and then pull the locking tongue 4 upward to disengage the protrusion 51 from the slot 52.

[0055] Example 4

[0056] like Figures 11-12 As shown, the difference between Embodiment 4 and Embodiment 3 is that the base 3 has a protrusion 51 on the top and the locking tongue 4 has a slot 52 at the bottom that allows the protrusion 51 to be detachably inserted into it.

[0057] In addition, in this embodiment, in order to facilitate the opening of a slot 52 on the latch 4, the slot 52 vertically penetrates the latch 4, and then a sealing member 43 is detachably inserted into the upper part of the slot 52.
