An oven hinge with a two-stage transmission mechanism

Abstract

The invention provides an oven hinge with a two-section type transmission mechanism. The oven hinge comprises a hinge base and a hinged arm, wherein the hinge base is arranged on an oven door body, the hinged arm is mounted on an oven cabinet body, a hinged shaft hinged to the hinge base is arranged at the lower end of the hinged arm, the hinged shaft is installed at the position close to the inner wall of the bottom end of the hinge base, and the hinge base is provided with a two-section type transmission device; the two-section type transmission device comprises a sliding frame, a transmission elastic component and a power-assisted elastic component, wherein the sliding frame is arranged on the hinge base in a sliding mode, the transmission elastic component has a buffer door weight anddoor hovering function, and the power-assisted elastic component has a door body opening and closing function, so that two-section type power transmission can be provided by the hinge base during opening and closing, the transmission elastic component provides the torque force for balancing the weight of an oven body, the function of turning on and hovering an oven door body at any angle is achieved, a large door closing force is provided by the power-assisted elastic component, and the automatic closing function of the oven door body is realized.

Description

technical field [0001] The invention relates to the technical field of oven hinges, in particular to an oven hinge with a two-stage transmission mechanism. Background technique [0002] The oven hinge generally includes a swing arm, a base, a spring, and a pull rod. The swing arm is installed on the oven door, the base is installed on the oven cabinet, the swing arm and the base are hinged, the spring is sleeved on the pull rod, and the pull rod is connected to the base and the swing arm. Then, relying on the pulling force or elastic force of the spring, using the way of twisting and pulling, when opening the door, the spring can be stretched or compressed by pulling the door open, so as to realize the opening of the oven door; when closing, just let go of the oven door, and the oven door will open Closed on the oven cabinet due to the return action of the spring. [0003] Yet there is following deficiency in the oven hinge of above-mentioned structure: [0004] 1. For the...

AI Technical Summary

Problems solved by technology

[0004] 1. For the sealing of the oven, springs with strong tension or elasticity are generally used, which makes it more laborious to open or close the oven door

[0005] 2. Using the transmission structure of spring and pull rod, it is easy to cause the pull rod to rub against the base during operation, resulting in high noise and reducing the stability of the oven rotation

[0006] 3. The use state of the oven door is limited, that is, it can only be fully opened or completely closed. It is difficult to stop the oven door arbitrarily according to the actual application, which affects the use effect

[0007] 4. During the rotation process of the oven door from closing to opening, the downward movement of the bottom edge of the oven door increases with the rotation of the swing arm of the oven hinge, so that the oven door sinks a lot during the door opening process, resulting in a gap between the oven door and the oven. Installed in furniture and cabinets to interfere and collide, affecting the normal opening and use of the oven door
