Description

Technical Field

[0001] This utility model relates to an object clamping assembly suitable for use in a dishwasher. This utility model also relates to a dishwashing device. Background Technology

[0002] Dishwashers are increasingly popular due to their superior cleaning performance, ability to sterilize tableware, and time and effort savings. Currently, most dishwashers on the market are designed for cookware and tableware. However, common kitchen items to be washed include not only cookware and tableware, but also greasy dishcloths and dish mats. Some families either wash these manually or combine them with other items in a washing machine. Manual washing is time-consuming and laborious, while washing machines can lead to cross-contamination of bacteria between dishcloths. Purchasing a washing machine specifically for dishcloths is expensive and, for small apartments, takes up valuable space, making already cramped living conditions even more uncomfortable.

[0003] To address the issue of dishcloth cleaning, Chinese utility model patent No. 201721877715.0 (authorization announcement No. CN208709825U) discloses a dishwasher, including a dishwasher shell, a water inlet pipe, and an inner tub. It also includes a dishcloth washing drum, which is housed within the dishwasher shell. The drain outlet of the inner tub drains water from the inner tub into the dishcloth washing drum via an inner tub drain valve. The water inlet of the dishcloth washing drum is also connected to the dishcloth washing drum's water inlet pipe. While this solution integrates the dishcloth washing drum into the dishwasher and solves the dishcloth cleaning problem, it increases the dishwasher's size and fails to address the issue of excessive space occupation. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide a clamping assembly that can clamp thin objects, in view of the above-mentioned technical status.

[0005] The second technical problem to be solved by this utility model is to provide a dishwasher that can clamp thin objects for cleaning, in view of the above-mentioned technical status.

[0006] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a clamp assembly, characterized in that it includes...

[0007] Base;

[0008] The first clamping arm has one end rotatably disposed on one side of the aforementioned base, has a first mating hole in the middle, and forms a first chuck at the other end;

[0009] The second clamping arm has one end rotatably mounted on one side of the aforementioned base, a second mating hole in the middle, and a second clamping head formed at the other end. The second clamping head is positioned close to the first clamping head and can engage with the first clamping head to clamp the object.

[0010] The adjusting rod has an external thread at its end and is disposed on the aforementioned first and second mating holes; and

[0011] A spring is sleeved on the aforementioned adjusting rod and located between the first clamping arm and the second clamping arm; the adjusting rod can adjust the distance between the first clamping arm and the second clamping arm when it is rotating.

[0012] The adjusting lever can be set in one of the following ways:

[0013] In the first configuration, the second chuck is located below the first chuck; the first mating hole has an internal thread adapted to the external thread of the aforementioned adjusting rod, and the adjusting rod passes through the second mating hole from bottom to top. The adjusting rod is provided with a limiting washer, the upper end face of which is in close contact with the lower end face of the second clamping arm.

[0014] In the second configuration, the second chuck is located below the first chuck; the second mating hole has an internal thread that matches the external thread of the aforementioned adjusting rod, and the adjusting rod is disposed through the first mating hole from top to bottom.

[0015] Of course, the first and second clamping arms here can also be arranged front and back in the horizontal direction.

[0016] Furthermore, a crossbar is provided perpendicular to the length of the adjusting rod. This crossbar acts as a handle, facilitating operation. Driving the crossbar causes the adjusting rod to rotate, thereby clamping or releasing it.

[0017] The preferred fit between the crossbar and the adjusting rod is as follows: the adjusting rod has a through hole, and the crossbar passes through the through hole.

[0018] Furthermore, the lower end face of the first clamp has a toothed first clamping groove, and correspondingly, the lower end face of the second clamp has a toothed second clamping groove, which cooperates with the aforementioned first clamping groove to clamp the object.

[0019] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a dishwasher, characterized in that it includes an inner tub and a clamping assembly disposed in the inner tub, the base of which is disposed on the inner wall of one side of the inner tub.

[0020] Compared with existing technologies, the advantages of this invention are as follows: A clamping assembly is installed on the inner wall of the inner drum. Rotation of the adjusting rod allows the first and second clamps to open and close, facilitating the cleaning of thin items such as dishcloths and dish heat-insulating mats. The clamping assembly is located on the side wall of the inner drum, occupying minimal space and maintaining the original volume of the dish rack inside the dishwasher, thus avoiding interference with dish rack placement due to the addition of a dishcloth cleaning function. Operation is simple, and the clamping is relatively secure. Attached Figure Description

[0023] Figure 3 for Figure 2 The exploded diagram. Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, the dishwasher in this embodiment includes an inner tub 100 and a clamp assembly 10 disposed within the inner tub 100.

[0026] During cleaning, the cloth to be cleaned is clamped by the clamping assembly 10, thereby achieving the purpose of cleaning the cloth. In this embodiment, there are two clamping assemblies, which allows for the diversification of cleaning objects.

[0027] like Figure 2 and Figure 3 As shown, the clamp assembly 10 in this embodiment includes a base 3, a first clamping arm 1, a second clamping arm 2, an adjusting rod 4, a spring 6, and a crossbar 5. The base 3 is located on the inner wall of one side of the inner liner 100.

[0028] The first clamping arm 1 is rotatably disposed on one side of the base 3, and has a first mating hole 12 in the middle. The other end forms a first chuck 11. The second clamping arm 2 is rotatably disposed on one side of the base 3, and has a second mating hole 22 in the middle. The other end forms a second chuck 21. The second chuck 21 is located below the first chuck 11 and can cooperate with the first chuck 11 to clamp objects. Specifically, the first clamping arm 1 and the second clamping arm 2 are rotatably disposed on the base 3 through a shaft pin 31.

[0029] The lower end face of the first clamp 11 has a toothed first clamping groove 111, and correspondingly, the lower end face of the second clamp 21 has a toothed second clamping groove 211. The second clamping groove 211 cooperates with the first clamping groove 111 to clamp the object.

[0030] The end of the adjusting rod 4 has an external thread 41 and is located on the first mating hole 12 and the second mating hole 22; the spring 6 is sleeved on the adjusting rod 4 and is located between the first clamping arm 1 and the second clamping arm 2.

[0031] The first mating hole 12 has an internal thread that matches the external thread 41 of the adjusting rod 4. The adjusting rod 4 passes through the second mating hole 22 from bottom to top. The adjusting rod 4 is provided with a limiting washer 7, the upper end face of which is in close contact with the lower end face of the second clamping arm 2.

[0032] A crossbar 5 is provided perpendicular to the length of the adjusting rod 4. The adjusting rod 4 has a through hole, and the crossbar 5 is inserted through the through hole. When the object is released or clamped, it acts on the crossbar, which can rotate downwards, thereby adjusting the distance between the first clamp 11 and the second clamp 21.

[0033] The adjusting rod moves up or down by engaging its external thread with the internal thread of the first mating hole. During the movement of the adjusting rod, the second chuck is raised or lowered by the limiting shim. The spring provides a preload between the first and second chucks, ensuring the clamp opening remains closed and providing a tactile feel during operation.
