Problems solved by technology

However, the multi-system refrigerators currently on the market are gradually unable to meet people's needs, because the multi-system refrigerators in the related art generally have the following problems: multi-system refrigerators on the market usually do not have variable temperature chambers, and cannot have both refrigeration and freezing functions. function; or even with variable temperature room, when the freezing function is changed to refrigeration function, it takes a long time, which is not conducive to food preservation; Low, unable to meet the needs of refrigerated storage temperature

specific Embodiment 1

[0081] Specific embodiment one, when ambient temperature ≥ setting ambient temperature (for example: 0~10 ℃), when the set temperature of variable room is adjusted from freezing (-6~-18 ℃) to refrigeration (1~10 ℃), at this time The temperature-changing room stops cooling, and the defrosting heating wire starts heating. When the temperature of the defrosting sensor is ≥ 0°C, the variable-temperature fan is ON.

[0082] Control 1: When the temperature Tm in the waiting room is greater than or equal to the set temperature TS-2 (that is, TS minus 2°C), the defrosting heating wire is turned off, and the variable temperature fan is turned off. At this time, the normal control of the greenhouse begins.

[0083] Control 2: When the temperature in the variable temperature chamber Tm ≥ the set temperature TS-2 (that is, TS minus 2°C), the defrosting heating wire is OFF, and the variable temperature fan temperature Tms ≥ the set temperature TS in the variable temperature room, the varia...

specific Embodiment 3

[0087] Specific embodiment three, the current ambient temperature is (0-10° C.), such as 9° C., and the user sets the set temperature of the variable room temperature as the refrigeration temperature, such as 7° C. It can be seen that the current ambient temperature is greater than the temperature set by the user; The current temperature of the greenhouse is a freezing temperature, such as -18°C. It can be seen that the user's demand is to change the variable temperature greenhouse from a freezer to a refrigerator. At this time, stop the cooling of the variable room, and turn on the heating function of the defrosting heating wire. When the defrosting temperature is determined to be greater than or equal to 0°C, turn on the variable temperature fan. By turning on the heating of the defrosting heating wire and the operation of the variable temperature fan, the temperature of the variable room is accelerated. Temperature return speed, when the temperature Tm of the variable room i...

specific Embodiment 4

[0088] Specific embodiment four, the user sets the set temperature of the variable room as the refrigeration temperature, such as 7°C, and the current ambient temperature is lower than the set temperature of the variable room, by determining that the temperature Tm of the variable room is lower than the set temperature TS of the variable room for more than a predetermined time , such as 2 hours, turn on the heating function of the variable temperature heating wire. When it is determined that the defrosting temperature is greater than or equal to 0°C, turn on the variable temperature fan to compensate the temperature Tm of the variable temperature chamber through the heat emitted by the defrosting heating wire. The temperature set by the user is reached. When the temperature Tm of the variable room is greater than or equal to the temperature lower than the set temperature TS of the variable room, for example, 2°C, stop the heating of the defrosting heating wire and turn off the...

Abstract

The invention provides a refrigerator control method. The refrigerator control method comprises the following steps: when a set temperature of a temperature change chamber is changed from a freezing temperature to a refrigerating temperature, the refrigeration of the temperature change chamber is stopped, and the heating of a defrosting heating wire in the temperature change chamber is started; and when the time of the temperature of the temperature change chamber being higher than or equal to the set temperature of the temperature change chamber reaches and exceeds a first set time, the heating of the defrosting heating wire is stopped. The invention further provides a refrigerator; and the refrigerator includes the temperature change chamber and the defrosting heating wire. Through the technical scheme, the refrigerator with the temperature change chamber stops the refrigeration of the temperature change chamber and opens the heating of the defrosting heating wire when the temperature change chamber is changed from a freezing chamber to a refrigerating chamber, so that the temperature return speed of the temperature change chamber is accelerated, the refrigerating temperature is quickly reached, the working efficiency of the refrigerator is improved, the problems of longer time, energy consumption and no facilitation of food preservation when converting the refrigerator with the temperature change function from the freezing function to the refrigerating function are prevented, and the user use comfort is improved.

Description

technical field [0001] The present invention relates to the technical field of refrigerators, in particular to a method for controlling a refrigerator and a refrigerator. Background technique [0002] Refrigerator is one of the essential household appliances in many families, which provides convenience for people's life. With the development of refrigerator technology and the continuous improvement of consumer demand, refrigerator technology gradually tends to be intelligent and multi-functional, so there are many System refrigerator. [0003] Such as Figure 5 Shown is a multi-system refrigerator proposed in the related art. Specifically, the multi-system refrigerator includes: a compressor 502, a condenser 504, a dry filter 506, an electric switching valve 508, a refrigeration capillary 510, a variable temperature capillary 512, a freezing capillary 514, a refrigeration evaporator 516, a variable temperature evaporator 518, Refrigerated evaporator 520. The basic working...
