Embodiment 1

[0034] like figure 1 As shown, the DC high-voltage power supply of the present invention includes a high-voltage trigger module and a boost module I and a boost module II connected to the high-voltage trigger module. and the high pressure required for sterilization. That is, booster module I obtains high pressure for freshness preservation, and booster module II obtains high pressure for sterilization.

[0035] figure 2 is based on figure 1 Schematic diagram of the structure of the fresh-keeping and sterilization device designed by the electrical principle diagram. The fresh-keeping and sterilization device of the present invention is mainly composed of an electric control board, a DC high-voltage power supply, and positive and negative ion discharge electrodes. The positive and negative ion discharge electrodes are composed of metal needles with oxidation resistance. AC voltage, and provide an electrical signal to control the selection switch to determine whether the DC h...

Embodiment 2

[0039] In this embodiment, the DC high-voltage power supply includes a high-voltage trigger module I and a high-voltage trigger module II and a booster module connected to the two high-voltage trigger modules at the same time. The high-voltage trigger module I and the high-voltage trigger module II adopt different current oscillation frequencies. The booster module obtains the high pressure required for fresh-keeping and sterilization respectively.

[0040] Figure 4 is based on image 3 Schematic diagram of the structure of the fresh-keeping and sterilization device designed by the electrical schematic diagram.

[0041] The structure of the fresh-keeping and sterilization device of this embodiment is consistent with the structure of Embodiment 1 in principle. Embodiment 1 obtains different high voltages by selecting different booster circuits, and this embodiment obtains different high voltages by selecting different high-voltage trigger circuits. In this structure, when th...

Abstract

The invention relates to the technical field of refrigerating equipment, particularly to a fresh-keeping and sterilizing device for a refrigerator and a control method. The fresh-keeping and sterilizing device for the refrigerator comprises an electric control board, a DC high voltage supply and an ionizer which are connected sequentially, wherein the ionizer comprises a positive ion discharge electrode and a negative ion discharge electrode; the output DC high voltage of the ionizer can be adjusted when input voltage is constant, and high voltages required by fresh keeping and sterilizing respectively are obtained. According to the invention, by adjusting the designed circuit of the DC high voltage supply inside the ionizer, switching to the output voltage of the ionizer is achieved, and the problem that a traditional ionizer for a refrigerator can only output a fixed DC high voltage and only can achieve the fresh keeping function or the sterilizing function when the input voltage is constant, is solved, in the invention, through intelligent control of the refrigerator, the combination of the fresh-keeping function and the sterilizing function is achieved, and the effect that one device ensures the sterilizing function and the fresh-keeping function at the same time inside the reefer of the refrigerator is achieved.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment, and more specifically, to a fresh-keeping and sterilization device for a refrigerator and a control method. Background technique [0002] With the improvement of living standards, refrigerators have entered thousands of households and become a necessity for household life. People have higher and higher requirements for the performance of refrigerators. Health, hygiene and safety have become the eternal theme of refrigerator technology development. [0003] Early refrigerators only relied on low temperature to keep food fresh, without the functions of sterilization and freshness preservation. The food in this kind of refrigerator, especially the food in the cold room is still spoiled after a long time, because bacteria still exist in the low temperature environment, not to mention ensuring sufficient moisture and nutrients in the food. Most of the bacteria in the refrigera...
