Problems solved by technology

In response to the above requirements, the conventional dual-temperature zone solution is to make the freezer room smaller and the refrigerator room larger. The disadvantage of this is: if the freezing function of the refrigerator is needed, the volume of the freezer room is not enough to achieve both. Balance between refrigerator volume and freezer volume

Embodiment 1

[0054] Embodiment 1. A method for controlling the freezing-to-refrigerating transition of a double-fan refrigerator. Combine below figure 1The control method for freezing to cold storage provided in this embodiment will be described.

[0055] see figure 1 The refrigerating fan and the freezing fan of the double-fan refrigerator in this embodiment can be arranged in the respective compartments, that is, the refrigerating fan is arranged in the refrigerating chamber, and the freezing fan is arranged in the freezing chamber, and both the refrigerating fan and the freezing fan can be arranged in the freezing chamber. Among them, the refrigerating fan and the freezing fan share one evaporator, which can save costs. Wherein, when both the refrigerating fan and the refrigerating fan are arranged in the freezing room, the refrigerating fan is covered with a fan hood, and the fan hood is provided with an air outlet channel, and the air outlet channel communicates with the refrigerati...

Embodiment 2

[0068] Embodiment 2. A method for controlling the freezing-to-refrigerating transition of a double-fan refrigerator.

[0069] See figure 2 , using a specific example to illustrate the control method for freezing to cold storage provided in this embodiment.

[0070] When the refrigerator is started to run, it is detected whether the setting of the refrigerator is the setting of freezing to refrigeration, if yes, the control mode of freezing to refrigeration is implemented; if not, the conventional control mode is implemented.

[0071] Among them, the control method of freezing to cold storage is mainly divided into the following steps:

[0072] Step 11, start the refrigerating fan and the freezing fan at the same time;

[0073] Step S12, respectively judge whether the temperature of the refrigerating room reaches the refrigerating temperature, and judge whether the temperature of the freezing room reaches the refrigerating temperature, for example, judge whether the temperat...

Embodiment 3

[0080] see image 3 The difference between this embodiment and the above-mentioned embodiment 2 lies in the control mode from freezing to refrigeration, and the control mode from freezing to refrigeration in this embodiment is:

[0081] a. Simultaneously start the refrigeration fan and the freezing fan;

[0082] b. Determine whether the temperature of the refrigerating room reaches the refrigerating temperature and whether the temperature of the freezing room reaches the refrigerating temperature, for example, judge whether the temperature of the refrigerating room reaches 4°C, if it reaches, control the refrigerating fan to stop, otherwise, control the refrigerating fan to continue Run; Similarly, judge whether the temperature of the freezer reaches 4°C, if it reaches, control the refrigeration fan to stop, otherwise, control the refrigeration fan to continue to run;

[0083] c. Every 20 minutes, judge whether the temperature of the refrigerating room is higher than 8°C, tha...

Abstract

The invention discloses a refrigeration-to-freezing control method and control system for a double-fan refrigerator and the double-fan refrigerator. The method includes the steps that S1, the refrigerator runs, whether the refrigerator is set to be converted from refrigeration to freezing or not is detected, S2 is executed if the refrigerator is set to be converted from refrigeration to freezing, and S4 is executed if the refrigerator is not set to be converted from refrigeration to freezing; S2, a refrigeration fan and a freezing fan are controlled to run, and when a refrigeration chamber and a freezing chamber reach a refrigeration temperature, the refrigeration fan and the freezing fan are controlled to stop rotating; S3, whether the temperature of the refrigeration chamber and the temperature of the freezing chamber are higher than a temperature setting value or not is detected, the refrigeration fan is controlled to run or the refrigeration fan and the freezing fan are controlled to run if the temperature of the refrigeration chamber and the temperature of the freezing chamber are higher than the temperature setting value, the temperature of the refrigeration chamber and the temperature of the freezing chamber keep within a refrigeration temperature scope, and the process is finished; and S4, the refrigeration fan and the freezing fan are controlled to run according to conventional setting. When the refrigeration food amount is larger, the freezing function of the freezing chamber can be converted into the refrigeration function, the functions of the overall refrigerator are converted into the refrigeration function, and the problem of large refrigeration amount is solved.

Description

technical field [0001] The invention relates to the technical field of refrigerator control, in particular to a control method for a double-fan refrigerator from freezing to refrigeration, a control method and a double-fan refrigerator. Background technique [0002] At present, most of the refrigerators in the refrigerator market are dual-temperature zone or multi-temperature zone refrigerators. Some of them have a variable temperature zone with a certain volume, but the variable temperature zone is generally small in volume; for the needs of some groups with religious beliefs: less meat, occasional The freezing function of the refrigerator will be used, and the cold room of the refrigerator will be used a lot. In response to the above requirements, the conventional dual-temperature zone solution is to make the freezer room smaller and the refrigerator room larger. The disadvantage of this is: if the freezing function of the refrigerator is needed, the volume of the freezer ...
