Embodiment 1

[0027] see figure 1 As shown, the present invention is a control method for a refrigerator with ice temperature preservation function, comprising at least a refrigerator provided with a refrigerator compartment 1 and a refrigeration system 2, the refrigerator compartment 1 is provided with an independent sealed area as an ice temperature preservation area 3, and the ice temperature The fresh-keeping area 3 is provided with an air inlet 6 and a return air outlet 7 communicating with the refrigeration system 2, while an infrared temperature sensor 11 electrically connected to the control panel 10 is installed in the ice-temperature fresh-keeping area 3, and an infrared temperature sensor 11 electrically connected to the control panel 10 is also installed. The connected heater 13, the control panel 10 is electrically connected with the display panel 15 installed on the refrigerator box, and the side wall of the ice temperature preservation area 3 is equipped with thermal insulatio...

Embodiment 2

[0029] see figure 2 Shown, the present invention is a kind of control method of the refrigerator with ice temperature preservation function, and the control steps are as follows:

[0030] Step 1, open the refrigerator, put the ingredients 14 to be kept fresh in the ice-warm fresh-keeping zone 3;

[0031] Step 2, input the name of the food material 14 through the display panel 15 installed on the refrigerator, the control panel 10 receives the input data of the display panel 15, and obtains the freezing point temperature data of the material 14 in the cloud database through the built-in WiFi module;

[0032] Step 3, the infrared temperature sensor 11 installed in the ice temperature preservation area 3 detects the temperature in the ice temperature preservation area 3 and feeds it back to the control panel 10;

[0033] If the detected temperature is higher than the freezing point temperature of the food material, the control panel 10 controls the opening of the air outlet dam...

Abstract

The invention discloses a control method of a refrigerator with an ice-temperature fresh-keeping function, and relates to the technical field of intelligent refrigerators. The method comprises the following steps of S1, opening the refrigerator, and putting the food material to be preserved into an ice-temperature fresh-keeping area; S2, inputting the name of the food material through a display panel installed on the refrigerator, controlling the panel 0 to receive input data of the display panel, and acquiring freezing point temperature data of the food material in the cloud database througha built-in WIFI module; and S3, detecting the temperature in the ice-temperature fresh-keeping area to be fed back to the control panel through an infrared temperature sensor installed in the ice-temperature fresh-keeping area. According to the method, the fruits and vegetables are stored under the condition of near freezing point temperature, the reduction of metabolic strength and killing of microorganisms are realized, and the extension of the preservation period is finally realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent refrigerators, and in particular relates to a control method for a refrigerator with the function of ice temperature preservation. Background technique [0002] Fruits and vegetables will continue to undergo metabolic activities of nutrient consumption after picking, resulting in continuous loss of nutrients. At present, fruits and vegetables are mostly stored in cold storage or refrigerators (2-8°C) after picking. Low temperature will inhibit microbial activity, reduce the metabolic activity of fruits and vegetables, and prolong the freshness period of fruits and vegetables. However, there is a limit to the improvement of the fresh-keeping period, and the refrigerated temperature cannot kill bacteria. [0003] Preliminary studies have found that, compared with temperature fluctuations in refrigerated storage (±2°C), when fruits and vegetables are stored near the freezing point (below 0°C) an...
