Problems solved by technology

However, this specific working method remains unchanged. Once it is set, it will not change according to the humidity of the environment outside the refrigerator. Therefore, there is a single program, which cannot effectively reduce the energy consumption of the refrigerator under the condition of anti-condensation.
[0003] In this way, people think of a method of controlling the working state of the refrigerator anti-condensation device by setting a device for detecting humidity on the refrigerator to achieve the above-mentioned purpose. For example, the patents disclosed in Japan are JP2002022342A and JP10339555A. A humidity sensor is installed to detect the humidity of the air so as to control the operation of the anti-condensation device on the refrigerator, but the above-mentioned document does not disclose what method is used in the device, and different working methods will inevitably bring different technical effects

Embodiment 1

[0023] In Embodiment 1, the entire humidity range is divided into 10 ranges in equal parts, that is, the entire humidity range is divided into a humidity range every 10%, and each humidity range in this division is defined as a humidity level G, and The working mode of the heating device under the corresponding grade G is stipulated. The working mode of the heating device here refers to the time ratio T of the heating device on and off, that is, the ratio of the heating device on and off time, which is specified in this embodiment The initial value of T is T0=1, and the on-off time ratio T of a grade G of the above-mentioned division and its corresponding heating device is, T=T0×(1+G), so when the humidity parameter in the air detected by the humidity sensor And after determining the humidity range in which the humidity parameter is located, the time ratio T of starting and stopping the heating device corresponding to the humidity parameter can be obtained. For example, when t...

Embodiment 2

[0024] In Example 2, the entire humidity range is divided into 5 humidity ranges in equal parts, that is, a humidity range is divided every 20%, each humidity range corresponds to a humidity level G, and the corresponding humidity is also specified. The working mode of the heating device under the level, which also refers to the time ratio T of the heating device on and off. In addition, the relational expression between the grade G and its corresponding time ratio T in this embodiment is the same as the relational expression in the first embodiment. In this way, although the number of divided humidity ranges in embodiment 2 is relatively small, in fact, it can more effectively ensure that the refrigerator does not produce condensation in each humidity range, because compared with the same humidity range in embodiment 1 This is due to the relatively high on-off ratio of the heating device used in the humidity range.

[0025] In the above two embodiments, the humidity range is...

Embodiment 3

[0026] In Embodiment 3, after the humidity range is divided according to the method in Embodiment 1, a buffer zone is set between adjacent humidity ranges to overcome the humidity error sensed by the humidity sensor itself. The humidity error of the humidity sensor mentioned here refers to the situation that the accuracy of the humidity sensor itself is not accurate or the ambient humidity is just on the dividing line of the humidity range. The working mode keeps changing, which seriously affects the heating effect of the anti-condensation heating device and the service life of the control module. However, after the buffer is set, the above situation can be effectively prevented from happening.

[0027] In Embodiment 1 of the present invention, the humidity of the air in the environment has been preliminarily divided into 10 humidity ranges. In Embodiment 3, there are The humidity area forms a buffer zone, and the buffer zone is equally divided in the adjacent humidity range....

Abstract

The invention relates to a working mode for heating anti-condensation cream on a refrigerator, in particular to a working mode for controlling the heating of anti-condensation cream by using a humidity sensor on a refrigerator. In the working mode, the humidity sensor arranged on the refrigerator senses the humidity of air at the outer side of the refrigerator to control the working mode of a heating device; and a continuous humidity range is preset in a refrigerator control module which judges a humidity range of an environmental humidity parameter detected by the humidity sensor to control the heating device to operate in the preset working mode. By the technical scheme of the invention, the energy consumption of the refrigerator can be flexibly, conveniently and effectively reduced while the anti-condensation cream is heated and an error interval of the humidity sensor on the service life of an anti-condensation cream device can be effectively avoided.

Description

technical field [0001] The invention relates to a working mode for anti-condensation heating on a refrigerator, in particular to a working mode for controlling anti-condensation heating on a refrigerator by using a humidity sensor. Background technique [0002] For refrigerators that control the anti-condensation heating to prevent condensation, the anti-condensation heating is often implemented by setting a fixed control program in the control module of the refrigerator. In the existing technology, this kind of setting usually directly sets the anti-condensation heating device at a higher start-stop ratio or keeps a longer working time to prevent condensation according to the ambient humidity, that is, only the anti-condensation The specific working mode of the condensation heating device ensures that the refrigerator does not condense under high humidity (for example, the humidity is above 85%), and at the same time, it can meet the requirement that the refrigerator also d...
