Compared with the prior art, the grid plate driven by the driving device is arranged below the cabinet door or the cabinet body of the cabinet, and the driving device drives the grid plate to move according to the temperature change so as to shield the air outlet area of the vent hole on the cabinet door or the cabinet body, so that the opening degree of the vent hole of the cabinet can be increased when the temperature of the cabinet is higher, the cold air quantity is increased, the air outlet area of the vent hole is reduced when the temperature is lower, the air inlet quantity is reduced, the cabinet can maintain better working temperature, and energy is saved. The driving device selects the existing novel material thermal bimetallic strip, the thermal expansion coefficients of the driving device and the driven device are different, when the temperature changes, the deformation of the driving layer is larger than that of the driven layer, so that the whole bimetallic strip can realize the driving of the grating plate by bending one side of the driven layer, the thermal bimetallic strip is not required to be provided with a temperature sensing device, and the driving structure is simple. The cabinet door or the cabinet body is provided with the bearing mechanism for bearing the grid plate, so that the moving resistance of the grid plate can be effectively reduced, and the driving of the thermal bimetallic strip on the grid plate is ensured.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Embodiment 1, as shown in fig. 1 and 2, the improvement of the present invention may be a cabinet door or a cabinet body 1, in this example, a cabinet door is taken as an example, a plurality of vent holes 2 are uniformly formed on the cabinet door, the vent holes 2 are in a strip hole shape, a grid plate 4 is disposed on the inner side or the outer side of the cabinet door, the grid plate 4 is attached to one surface of the cabinet door (there is a gap and is not in contact with the surface), a driving device is installed on the cabinet door, the driving device is a thermal bimetallic strip 8 with different thermal expansion and contraction rates, the thermal bimetallic strip 8 is arranged perpendicular to the cabinet door or the cabinet body 1, one end of the thermal bimetallic strip is connected to the cabinet door through a fixing seat 5, the other end is connected to the grid plate 4 through a connecting seat 6, during installation, a partition strip of the grid plate 4 shields a half of the vent holes 2 or completely staggers the vent holes 2, when the temperature is higher, the thermal bimetallic strip 8 is bent, so that the grid plate 4 moves, further increases the air outlet area of the vent holes 2, on the contrary, the division bars of the grating plates 4 further cover the vent holes 2, and the area of the vent holes 2 is reduced. The thermal bimetallic strip is also called as a bimetallic strip, and because the thermal expansion coefficients of all component layers are different, when the temperature changes, the deformation of the active layer is larger than that of the passive layer, so that the whole bimetallic strip can bend towards one side of the passive layer, and the curvature of the composite material changes to generate deformation. Among them, the one with a higher expansion coefficient is called an active layer, and the one with a lower expansion coefficient is called a passive layer. However, as the application field of the bimetal expands and the bonding technology advances, three-layer, four-layer and five-layer bimetal materials are developed in recent times. In fact, any composite material that changes shape depending on temperature changes is still traditionally referred to as thermal bimetal.

Embodiment 2, as shown in fig. 3, 4 and 5, to further reduce the stress of the bimetal 8, a bearing mechanism is arranged on the periphery of the inner wall of the cabinet door, the bearing mechanism contacts with the side wall of the grid plate 4, and the bearing mechanism is a sliding groove or more than two rolling bearings arranged on the inner surface or the outer surface of the cabinet door or the cabinet body 1, preferably 8, 2 on each side. The one end of hot bimetallic strip 8 is passed through fixing base 5 and is connected on cabinet door or cabinet body 1, and the other end passes through connecting seat 6 to be connected at the grid board, all is equipped with the draw-in groove of the hot bimetallic strip 8 of joint on fixing base 5 and connecting seat 6, adopts the joint convenience to change hot bimetallic strip 8.

The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and the practical application, to thereby enable others skilled in the art to best utilize the invention.
