Technical Field

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

[0002] With social development and technological advancements, people's demands for a better life are increasing. More and more families are using dishwashers, which not only bring convenience but also save time. However, dishwashers have many components that need to be detachably connected. For example, the door lock structure between the door and the cabinet needs to be detachably connected to open and close the door. This usually requires a motor, as illustrated in Chinese invention patent application CN201911120674.4 (publication number CN112806937A), entitled "A Door Lock Structure and a Cleaning Machine with the Door Lock Structure." Similarly, the water pipe and spray arm need to be detachably connected to facilitate subsequent maintenance and replacement of faulty parts, as illustrated in Chinese utility model patent application CN202121481021.1 (publication number CN215502854U), entitled "An Upper Spray Arm Connection Structure for a Cleaning Machine and a Cleaning Machine." However, this rotating connection method makes disassembly and assembly quite cumbersome.

[0003] Therefore, it is essential to design a connection structure that allows the two components to be detachably connected. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide a connection structure for a dishwasher that allows for easy assembly and disassembly of two components, in light of the current state of the technology.

[0005] The second technical problem to be solved by this utility model is to provide a dishwasher that uses the above-mentioned connection structure, in view of the current state of the prior art.

[0006] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a connection structure for a dishwasher, used to detachably connect a first component and a second component of the dishwasher, characterized in that the connection structure includes...

[0007] The box body has an opening at the top and perforations on its side walls, and is used to be mounted on the first component;

[0008] A locking element is provided in the box body. The locking element can move laterally relative to the box body, so that the locking element can partially pass through the through hole or retract into the box body. The part of the locking element that can pass through the through hole is called the locking part.

[0009] A lock hole is arranged on the second component, and the lock hole corresponds to the through hole. The lock hole is capable of allowing the locking part to be detachably inserted therein.

[0010] A first elastic member acts on the locking member, so that the locking member keeps the locking part moving in the direction of retracting into the box body.

[0011] A pressing member is arranged in the box body and is capable of moving up and down relative to the box body. The pressing member is capable of pushing the locking member in the state of moving upward, so that the locking part moves toward the lock hole. The pressing member is capable of moving upward to the state that the top of the pressing member is located in the opening, and in this state, the pressing member is in abutment with the locking member, and the locking part is inserted into the lock hole through the through hole.

[0012] The pressing member is capable of moving downward to the state that the pressing member is out of abutment with the locking member.

[0013] A second elastic member acts on the pressing member, so that the pressing member keeps moving upward.

[0014] In order to make the pressing member push the locking member in the state of moving upward, so that the locking part moves toward the lock hole, a first inclined surface extending from top to bottom toward the side wall of the box body is arranged on the pressing member, and a second inclined surface extending from top to bottom toward the side wall of the box body is arranged on the locking member. The first inclined surface is located below the second inclined surface and the two are capable of being in abutment.

[0015] In the above scheme, the pressing member includes a vertically extending pressing rod and a pushing part arranged on the peripheral wall of the pressing rod. The top of the pressing rod is capable of being located in the opening. The locking member is located beside the pressing rod. The pushing part extends toward the locking member. The first inclined surface is arranged on the pushing part. The pushing part is capable of being in abutment with the inner wall surface of the top wall of the box body, so as to limit the upward moving stroke of the pressing rod.

[0016] Preferably, the pushing part has at least two pushing parts which are spaced apart along the circumference of the pressing rod. Correspondingly, the locking member, the through hole and the lock hole also have at least two. In this way, the first component and the second component are connected by multiple points, and the connection reliability is high.

[0017] In order to facilitate the arrangement of the pressing member, the locking member and other components in the box body, the box body includes an upper shell and a lower shell which are capable of being connected. The upper shell and the lower shell jointly enclose a containing space for containing the locking member and the pressing member. The opening is arranged on the top wall of the upper shell, and the through hole is arranged on the side wall of the lower shell. In this way, the pressing member, the locking member and other components are first installed in the lower shell, and then the upper shell and the lower shell are connected.

[0018] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a dishwasher, characterized in that: it includes a first component, a second component and the above-mentioned connecting structure, the first component is a cabinet with an open front side, the cabinet is located on the top of the cabinet, the second component is a door that is movably located on the front side of the cabinet, the door can open or close the open side of the cabinet, the top of the door is provided with a locking rod that extends to the side of the cabinet when it is closed, and the lock hole is located on the locking rod.

[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 first component, a second component, and the above-mentioned connecting structure. The first component is a spray arm, the second component is a water pipe, a water inlet is provided on the top wall of the spray arm, the box body is provided on the top wall of the spray arm and covers the water inlet, and the top and bottom walls of the box body are provided with water outlets connected to the water inlet. The periphery of the water pipe surrounds the outer periphery of the box body, and the inner peripheral wall of the water pipe is provided with the lock hole.

[0020] To facilitate pressing the pressing component, the top wall of the water pipe is provided with a through hole for the tool for pressing the pressing component to pass through, and the through hole is located directly above the opening of the box body.

[0021] Compared with the prior art, the advantages of this utility model are as follows: This utility model is provided with a pressing member and a locking member. When the pressing member is pressed down, the pressing member and the locking member are disengaged. The locking member will move laterally under the action of the first elastic member, and the locking part will disengage from the lock hole and retract into the box. At this time, the first component and the second component can be disassembled. When it is necessary to connect the first component and the second component, since the pressing member is in the upper limit position under the action of the second elastic member and the locking part protrudes through the through hole, the pressing member must be pressed down first to retract the locking part into the box. When the through hole and the lock hole are aligned, the pressing member is released. The pressing member moves upward under the action of the second elastic member until the top of the pressing member moves into the opening of the box. In this state, the pressing member and the locking member abut against each other, and the locking part protrudes through the through hole and is inserted into the lock hole, thus realizing the connection of the first component and the second component.

[0022] As can be seen from the above, the assembly and disassembly of the first and second components only require pressing the pressing part, which is quite convenient. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] like Figures 1 to 4 As shown, the dishwasher of this preferred embodiment includes a first component 1, a second component 2, and a connecting structure, the connecting structure being used to detachably connect the first component 1 and the second component 2 of the dishwasher.

[0031] The connecting structure includes a housing 3, a locking element 4, a lock hole 5, a first elastic element 41, a pressing element 6, and a second elastic element 61.

[0032] The top of the box body 3 is provided with an opening 31, and the side wall of the box body 3 is provided with a perforation 32. The box body 3 is installed on the first component 1.

[0033] The locking member 4 is located in the box body 3. The locking member 4 can move laterally relative to the box body 3, so that the locking member 4 can partially pass through the through hole 32 or retract into the box body 3. The part of the locking member 4 that can pass through the through hole 32 is called the locking part 42.

[0034] The lock hole 5 is provided on the second component 2, and the lock hole 5 is provided corresponding to the through hole 32. The lock hole 5 allows the locking part 42 to be detachably inserted into it.

[0035] The first elastic element 41 acts on the locking element 4, causing the locking element 4 to maintain the tendency of the locking part 42 to move in the direction of retracting the box body 3. In this embodiment, the first elastic element 41 is a spring, with one end abutting against the locking element 4 and the other end abutting against the side wall surface of the box body 3.

[0036] The pressing member 6 is disposed in the box body 3 and can move up and down relative to the box body 3. When the pressing member 6 moves upward, it can push the locking member 4 so that the locking part 42 moves toward the lock hole 5. In this embodiment, the pressing member 6 is provided with a first inclined surface 62 extending from top to bottom toward the side wall of the box body 3, and the locking member 4 is provided with a second inclined surface 43 extending from top to bottom toward the side wall of the box body 3. The first inclined surface 62 is located below the second inclined surface 43 and the two can abut against each other so that when the pressing member 6 moves upward, it can push the locking member 4 so that the locking part 42 moves toward the lock hole 5.

[0037] The pressing member 6 can move upward until its top is in the opening 31. In this state, the pressing member 6 abuts against the locking member 4, and the locking part 42 is inserted into the lock hole 5 through the through hole 32. The pressing member 6 can move downward until it is no longer in contact with the locking member 4.

[0038] The pressing member 6 includes a vertically extending pressing rod 63 and a pushing part 64 provided on the peripheral wall of the pressing rod 63. The top of the pressing rod 63 can be located in the opening 31. The locking member 4 is located on the side of the pressing rod 63. The pushing part 64 extends toward the locking member 4. A first inclined surface 62 is provided on the pushing part 64. The pushing part 64 can abut against the inner wall surface of the top wall of the box body 3 to limit the upward movement stroke of the pressing rod 63.

[0039] The second elastic element 61 acts on the pressing element 6, causing the pressing element 6 to maintain an upward movement tendency. In this embodiment, the second elastic element 61 is a spring, with its lower end abutting against the bottom wall of the box 3 and its upper end abutting against the bottom wall of the pressing rod 63.

[0040] The pushing part 64 has at least two parts spaced apart circumferentially along the pressing rod 63. Correspondingly, there are also at least two locking elements 4, through holes 32, and lock holes 5. This provides a multi-point connection between the first component 1 and the second component 2, resulting in high connection reliability. In this embodiment, there are two pushing parts 64.

[0041] The housing 3 includes an upper shell 33 and a lower shell 34 that can be joined together. The upper shell 33 and the lower shell 34 together enclose a space for accommodating the locking member 4 and the pressing member 6. An opening 31 is provided on the top wall of the upper shell 33, and a through hole 32 is provided on the side wall of the lower shell 34. Thus, the pressing member 6, the locking member 4, etc. are first installed in the lower shell 34, and then the upper shell 33 and the lower shell 34 are connected together.

[0042] In this embodiment, the first component 1 is a box with an open front side, and the box body 3 is located on the top of the box. The second component 2 is a door that is movably located on the front side of the box. The door can open or close the opening of the box. The top of the door is provided with a locking rod 20 that extends to the side of the box body 3 when it is closed, and a lock hole 5 is provided on the locking rod 20.

[0043] The disassembly and assembly process of the first component 1 and the second component 2 is as follows:

[0044] Press down on the pressing part 6 so that the pressing part 6 is disengaged from the locking part 4. The locking part 4 will move laterally under the action of the first elastic part 41, and the locking part 42 will disengage from the lock hole 5 and retract into the box 3. At this time, the first part 1 and the second part 2 can be disassembled.

[0045] When it is necessary to connect the first component 1 and the second component 2, the pressing member 6 is in the upper limit position under the action of the second elastic member 61, and the locking part 42 protrudes through the through hole 32. Therefore, the pressing member 6 needs to be pressed first so that the locking part 42 retracts into the box body 3. When the through hole 32 and the lock hole 5 correspond, the pressing member 6 is released. The pressing member 6 moves upward under the action of the second elastic member 61 until the top of the pressing member 6 moves into the opening of the box body 3. In this state, the pressing member 6 abuts against the locking member 4, and the locking part 42 protrudes through the through hole 32 and is inserted into the lock hole 5, thus realizing the connection between the first component 1 and the second component 2.
