[0039] Embodiment:
[0040] Referring to Figure 1 and Figure 5 , the embodiment provides a kitchen appliance, which comprises a cabinet body 100, a cabinet door 200 and a door control assembly. The kitchen appliance can be a refrigerator or a sterilizer.
[0041] The cabinet door 200 is rotatably arranged on the cabinet body 100, and the door control assembly can control the rotation of the cabinet door 200 to open and close the cabinet body 100. Correspondingly, the door control assembly has an open door state and a closed door state.
[0042] Referring to Figures 2-4 and Figures 6-8 , the door control assembly comprises a base 1, a first linear actuator 2, a first sliding block 3, a first connecting rod 4, a second connecting rod 5 and a third connecting rod 6.
[0043] The base 1 is fixed on the top of the cabinet body 100. The first linear actuator 2 is mounted on the base 1 along a first direction, and the first linear actuator 2 can be extended and retracted along the first direction. In this embodiment, the first linear actuator 2 is an electric push rod. The first linear actuator 2 is the power source of the door control assembly, and the first linear actuator 2 can control the door control assembly to switch between the open door state and the closed door state through the extension and retraction action.
[0044] The output end of the first linear actuator 2 is provided with a linear sliding groove 21 extending along a second direction, and the first sliding block 3 is slidingly arranged at the linear sliding groove 21 to allow the first sliding block 3 to move linearly along the second direction on the output end of the first linear actuator 2. The second direction is arranged obliquely relative to the first direction, and in general cases, the second direction is perpendicular to the first direction.
[0045] The first connecting rod 4 has a first end 41 and a second end 42, the second connecting rod 5 has a third end 51 and a fourth end 52, and the third connecting rod 6 has a fifth end 61 and a sixth end 62. The first end 41 is rotatably connected with the first sliding block 3, the third end 51 and the second end 42 are rotatably connected, the fourth end 52 is rotatably arranged on the third connecting rod 6 and is spaced apart from the fifth end 61, the fifth end 61 is rotatably arranged on the base 1, and the third connecting rod 6 is connected with the cabinet door 200.
[0046] With reference to Figure 2 and Figure 6 , the telescopic action of the first linear driver 2 can be converted into the rotating action of the third connecting rod 6, thereby controlling the cabinet door 200 to rotate clockwise or counterclockwise. Thus, the first linear driver 2 can not only control the cabinet door 200 to open automatically, but also control the cabinet door 200 to close automatically, realizing the automatic control of the opening and closing of the cabinet door 200 and improving the automation and intelligence of the kitchen appliance.
[0047] In order to improve the stability of the rotating process of the third connecting rod 6, the sixth end 62 is provided with a second sliding block 63, and the base 1 is provided with an arc-shaped sliding groove 11, and the second sliding block 63 is slidingly arranged at the arc-shaped sliding groove 11. The fourth end 52 and the sixth end 62 are arranged at intervals, so that the fourth end 52 avoids the second sliding block 63.
[0048] Preferably, the door control assembly further comprises a first sheet metal part 7 and a second sheet metal part 8. The first sheet metal part 7 is fixed on the base 1 to increase the strength of the base 1, and the second sheet metal part 8 is rotatably arranged on the first sheet metal part 7, and the second sheet metal part 8 is fixed with the top edge of the cabinet door 200. Correspondingly, the cabinet door 200 can be rotatably arranged on the cabinet body 100 through the second sheet metal part 8, the first sheet metal part 7 and the base 1.
[0049] The second sliding block 63 is fixed with the second sheet metal part 8, and the third connecting rod 6 can control the rotation of the cabinet door 200 through the second sliding block 63 and the second sheet metal part 8.
[0050] With reference to Figure 3 and Figure 4 , the first sheet metal part 7 is at least partially located at the end of the arc-shaped sliding groove 11. When the door control assembly is in the open door state, the second sliding block 63 abuts against the first sheet metal part 7, and the first sheet metal part 7 limits the second sliding block 63, preventing the second sliding block 63 from being separated from the arc-shaped sliding groove 11.
[0051] With reference to Figure 2 , the door control assembly further comprises a fourth connecting rod 9, and the two ends of the fourth connecting rod 9 are respectively fixed on the second sliding block 63 and the second sheet metal part 8. The second sliding block 63 increases the distance from the second sheet metal part 8 through the fourth connecting rod 9. When the door control assembly is in the open door state, the fourth connecting rod 9 is at least partially located outside the arc-shaped sliding groove 11, so as to allow the cabinet door 200 to be in a fully open state.
[0052] With reference to Figures 6-8 , when the door control assembly is in the closed door state, the fourth connecting rod 9 is at least partially located inside the arc-shaped sliding groove 11. In order to enable the fourth connecting rod 9 to smoothly enter and exit the arc-shaped sliding groove 11, the fourth connecting rod 9 is an arc-shaped rod in this embodiment, and the fourth connecting rod 9 extends along the circumference of the arc-shaped sliding groove 11. In addition, with reference to Figure 3The first sheet metal part 7 is provided with a clearance hole 71, and the fourth connecting rod 9 is arranged in the clearance hole 71, so that the fourth connecting rod 9 can enter and exit the arc-shaped sliding groove 11 through the clearance hole 71, and meanwhile, the first sheet metal part 7 can limit the second sliding block 63.
[0053] Referring to Figure 5 and Figure 6 Notably, when the door control assembly is in the door closing state, the cabinet door 200 abuts against the cabinet body 100, so that the cabinet door 200 can limit the rotation angle of the third connecting rod 6 through the second sheet metal part 8, the fourth connecting rod 9 and the second sliding block 63, and the second sliding block 63 is also ensured not to be separated from the arc-shaped sliding groove 11.
[0054] The technical features of the above-described embodiments can be combined in any manner, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.
[0055] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, however, it should not be understood as the limitation of the scope of the present application. It should be pointed out that, for the ordinary skilled in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
