Problems solved by technology

When there is a large gap with the actual ambient temperature and humidity, the energy consumption will be greatly increased
[0004] On the other hand, due to the lower limit of the switching frequency of the relay itself, the switching frequency of the heating wire controlled by it is also lower.
When the temperature ...

Embodiment Construction

[0038] First, the principle of the present invention is briefly explained. In the present invention, a non-contact switch device is set to control the start and stop of the heating device, so that the control speed is increased, and the temperature fluctuation is further reduced. And by arranging a temperature sensor at the beam body (the general designation for the body of the sealing beam and the dividing beam), the temperature obtained is compared with the first set temperature obtained in real time by ambient temperature and humidity to control the start and stop of the heating device , making the control more scientific and accurate, and reducing energy consumption.

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] refer to figure 1 , shows a schematic structural view of an embodiment of the anti-condensation refrigerator of the present invention. As shown in the figure, it includes a box body 10; ...

Abstract

The invention discloses an anti-condensation refrigerator. The anti-condensation refrigerator comprises a heating device which is arranged on a sealing beam and/or a separation beam to heat the sealing beam and/or the separation beam, a temperature sensor which is arranged on the sealing beam and/or the separation beam to detect the temperature of the sealing beam and/or the separation beam, and a control system which comprises a controller and a contactless switch device, wherein the controller controls the start-stop of the heating device through the contactless switch device under the monitoring of the temperature sensor to ensure that the temperature of the sealing beam and/or the separation beam is always higher than first set temperature. The heating device is controlled by the contactless switch device, so control rate is higher, temperature fluctuation is small, and energy consumption is reduced. The invention also discloses an anti-condensation control method.

Description

technical field [0001] The invention relates to the field of household equipment, in particular to an anti-condensation refrigerator and an anti-condensation control method. Background technique [0002] The heating wires in traditional sealing beams and partition beams are controlled by electromechanical relays, and the anti-condensation working method is mainly time-controlled. For example, the heating wires are turned on for 50 minutes and stopped for 10 minutes, which is relatively fixed. In the case of different ambient temperatures and different humidity, sometimes the heating temperature is not enough, and then the temperature of the sealing beam or the partition beam is lower than the dew point, resulting in condensation phenomenon. [0003] Therefore, in order to achieve the purpose of anti-condensation, the heating wire start-stop ratio can only be set according to the most unfavorable conditions. That is, if both the ambient temperature and the humidity are set t...
