Anti-condensation refrigerator and anti-condensation control method

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...

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 of the beam body is lower than the dew point temperature, the heating wire works. Due to the slow response of the mechanical contacts of the relay, the temperature of the beam body is often higher than the dew point temperature before the heating wire stops working, so it will inevitably cause waste of energy consumption.
