Description
Technical Field
[0001] The utility model relates to the field of vehicle-mounted microwave ovens, in particular to a vehicle-mounted microwave oven with a tightly closable door. Background Art
[0002] In existing pull-down door microwave ovens, since the microwave oven door needs to maintain closing force to control microwave leakage, the hinge of the pull-down door needs to maintain closing force, control door opening damping and other functions, resulting in a complex structure and high cost. Utility Model Content
[0003] In order to solve the above problems, the present technical solution provides a vehicle-mounted microwave oven with a tightly closable door.
[0004] To achieve the above purpose, the technical solution is as follows:
[0005] A vehicle-mounted microwave oven with a tightly closable door comprises a microwave oven body, wherein the microwave oven body is provided with a door body, wherein hinges are provided below two sides of the microwave oven body, and ends of the hinges are hingedly connected to the door body;
[0006] A through hole is provided above the front door plate of the microwave oven body, a clamping portion is provided on the inner side of the through hole, and the door body is provided with a door hook which first passes through the through hole and then cooperates with the clamping portion, and the door hook can be elastically clamped.
[0007] In some embodiments, the door hook is rotatably arranged on the door body through a rotating seat, and a tension spring is provided in the frame of the door body, and the tension spring is also connected to the door hook.
[0008] In some embodiments, a first micro switch is provided on one side of the engaging portion for detecting whether the door hook is engaged in place.
[0009] In some embodiments, a second micro switch is provided on one side of the clamping portion, and a rotating portion is provided that is rotatably arranged inside the microwave oven body for cooperating with the door hook.
[0010] In some embodiments, a raised step is provided on the lower end surface of the door hook.
[0011] In some embodiments, the pulling force of the door hook is 0.2-1.5 times the weight of the front door panel of the microwave oven body.
[0012] The beneficial effects of this application are:
[0013] This application adopts a hinge structure to allow the door body to be flipped up. In addition, the door hook of the door body is engaged with the clamping part through elastic deformation, so that the door body can be tightly closed to prevent microwave leakage. In this way, this application replaces the structure of the damping switch door, making the product structure simpler and more reliable, reducing costs and improving product competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments.
[0015] Figure 1 This is a schematic diagram of the structure of the embodiment of the utility model Figure 1 ;
[0016] Figure 2 This is a schematic diagram of the structure of the embodiment of the utility model Figure 2 . DETAILED DESCRIPTION
[0017] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0018] Please refer to Figure 1-2 As shown, a vehicle-mounted microwave oven with a tightly closable door comprises a microwave oven body, wherein the microwave oven body is provided with a door body 1, wherein hinges 2 are provided below both sides of the microwave oven body, and the ends of the hinges 2 are hingedly connected to the door body 1;
[0019] A through hole 3 is provided above the front door panel of the microwave oven body, and a clamping portion 4 is provided on the inner side of the through hole 3. The door body 1 is provided with a door hook 5 that first passes through the through hole 3 and then cooperates with the clamping portion 4. The door hook 5 can be elastically clamped.
[0020] This application adopts a hinge structure to allow the door body to be flipped up. In addition, the door hook of the door body is engaged with the clamping part through elastic deformation, so that the door body can be tightly closed to prevent microwave leakage. In this way, this application replaces the structure of the damping switch door, making the product structure simpler and more reliable, reducing costs and improving product competitiveness.
[0021] In this embodiment, the door hook 5 is rotatably arranged on the door body 1 through a rotating seat 51. A tension spring 6 is provided in the frame of the door body 1. The tension spring 6 is also connected to the door hook 5. One end of the tension spring is fixed in the frame of the door body, and the other end passes through the door hook. Since the door hook is rotatably arranged on the door body, when the door is closed, the shape of the clamping part forces the door hook to flip over until the door hook is clamped in the clamping part. The tension spring resets and tightens the door hook to make the door hook tightly fit with the clamping part.
[0022] In this embodiment, a first micro switch 7 is provided on one side of the clamping portion 4 for detecting whether the door hook 5 is locked in place. When the door hook is fully engaged in the clamping portion, the door hook will trigger the first micro switch. If the door hook is not locked in place, the first micro switch will feed back to the main control board to stop the heating operation.
[0023] In this embodiment, a second microswitch 8 is provided on one side of the clamping portion 4, and a rotating portion 9 is rotatably arranged inside the microwave oven body for cooperating with the door hook 5. When the door hook is clamped in, the end of the door hook will push the rotating portion to flip so that the rotating portion triggers the second microswitch. If either of the two microswitches detects that the door hook fails to be clamped in place, the heating operation will be stopped, thereby playing a double protection role.
[0024] In this embodiment, the lower end surface of the door hook 5 is provided with a raised step 10, which has an abutting effect when engaged, ensuring that the door body is completely closed.
[0025] In this embodiment, the pulling force of the door hook 5 is 0.2-1.5 times the weight of the front door panel of the microwave oven body.
[0026] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other embodiments whose principles and basic structures are the same or similar to those of the present application are within the scope of protection of the present application.
