Problems solved by technology

Under working conditions, since the air valve is prone to frost condensation, the deposited ice particles will have a negative impact on the adjustment accuracy of the valve position, and the reliability of the air valve opening adjustment is relatively poor, and in severe cases, it will affect the opening and closing of the air valve Further, even if the above-mentioned structure eliminates the technical defect of frost stuck valve position, due to the influence of the different positions of goods in the refrigerating room and the location of the goods, even if the position of the fixed air valve remains unchanged, the refrigerating temperature in the refrigerating room will still be relatively high. Large fluctuations, if this temperature fluctuation cannot be adjusted in time, it will adversely affect the quality of the stored goods in serious cases

Embodiment 1

[0030] Without loss of generality, as figure 1 As shown, the present invention provides a smart damper, including: a damper frame 100, a damper baffle 200 and a stepping drive device 300; the damper baffle 200 is hinged in the damper frame 100 through a hinge shaft; The shaft is firmly connected with the damper baffle 200 ;

[0031] figure 2 In the present embodiment shown, the damper baffle 200 is hinged in the damper frame 100 through a rotating shaft, and one side of the damper frame 100 is provided with a stepping drive device 300, and the stepping motor 301 in the stepping drive device 300 is hinged with the gear 302. The shaft 303 is connected by transmission, and the stepping motor 301 and the transmission gear 302 are both arranged in the housing 304 on one side of the damper frame 100 , and the housing 304 is snapped and sealed by an end cover 305 . It should be noted that since the power source of the stepping drive device is not limited to the stepping motor, and...

Embodiment 2

[0037] Figure 5 As shown, on the basis of Embodiment 1, the present embodiment is provided with multiple damper baffles 200 , and each damper baffle 200 is provided with an independent stepping drive device 300 . In the present invention, by setting the number of damper baffles in the same damper frame to multiple pieces, it is helpful to achieve the technical effect of improving the control accuracy of the intelligent damper, and the stepwise regulation and control of ventilation can be achieved by sequentially opening the damper baffles arranged in the damper frame Quantitative technical effects.

[0038] Preferably, in a preferred technical solution of this embodiment, the damper frame is provided with a frame heating device. The present invention helps to achieve the technical effect of melting and condensing frost on the damper frame by providing a heating device on the damper frame. The closed smart damper will also cause the damper to fail to open automatically, whic...

Embodiment 3

[0040] Such as Image 6 As shown, in this embodiment, on the basis of Embodiment 1, one side of the damper frame 100 is provided with a V-shaped groove 110, and a temperature sensor 111 and a wind speed sensor 112 are arranged in the V-shaped groove 110, and the temperature sensor 111 and the wind speed sensor 112 are respectively connected with the controller signal of the stepping drive device. The present invention provides a strong structural support for setting a temperature sensor and a wind speed sensor in the V-shaped groove by setting a V-shaped groove on one side of the damper frame, and the temperature sensor installed in the V-shaped groove can realize real-time Monitoring, the controller of the stepping drive device can adjust the valve opening of the smart air valve in real time according to the feedback of the airflow temperature and the storage temperature in the refrigerating room, thereby achieving the technical effect of intelligently regulating the room tem...

Abstract

The invention discloses an intelligent air valve having the technical advantages that the structure is simple and the valve opening is adjusted flexibly. The intelligent air valve structurally comprises an air door frame, an air door damper and a step driving device; the air door damper is hinged to the inside of the air door frame via an articulated shaft; the articulated shaft is fixedly connected with the air door damper; and the step driving device is in transmission connection with the articulated shaft of the air door damper. According to the intelligent air valve having the structure, the technical effect of automatically adjusting the valve opening can be achieved. When the intelligent air valve is used, pulse signals are transmitted to a power device of the step driving device through a controller, the opening angle of the air valve can be accurately controlled, and strong structure support is provided for flexibly controlling cold air inlet volume in a refrigerating chamber.

Description

technical field [0001] The invention relates to the technical field of automatic control of air valves in refrigerating chambers, in particular to an intelligent air valve. Background technique [0002] In the prior art, an air duct with a damper is still used to establish an airflow connection between the refrigerator compartment and the freezer compartment of some large refrigerators or freezers, and the technical effect of controlling the storage temperature of the refrigerator compartment is achieved by adjusting the opening of the damper. The air valves arranged in the air ducts in the prior art generally need to use manual rotary control switches to control the opening of the valves. Under working conditions, since the air valve is prone to frost condensation, the deposited ice particles will have a negative impact on the adjustment accuracy of the valve position, and the reliability of the air valve opening adjustment is relatively poor, and in severe cases, it will a...
