Description
Technical Field
The invention belongs to the field of household appliances, and particularly relates to a temperature adjusting system, a refrigerator and a temperature adjusting method of the refrigerator.
Background
At present, with the economic development and the improvement of living standard, the demand of the user on the refrigerator is higher and higher when the food is preserved or stored, for example: in daily life, some users need to store special food materials such as red wine and tea leaves, for example, the optimal storage temperature of the red wine is 12 ℃, and a refrigerator is required to have a larger temperature regulation range.
At present, the refrigerator which has heating and refrigerating functions and can adjust the temperature in a large range is available in the market, and the control rule of a refrigerator storeroom is as follows:
the corresponding relation between the temperature of the starting and stopping point of the heating mode of the storage chamber of the refrigerator and the set temperature (preservation temperature set by a user) is as follows: the temperature of the starting point of the heating wire is less than the temperature of the set value and less than the temperature of the shutdown point of the heating wire; the corresponding relationship between the start-up and stop point temperature and the set point temperature in the refrigeration mode is as follows: the temperature of the air door at the shutdown point is less than the set value temperature and less than the temperature of the air door at the startup point.
As shown in figure 1As shown, in the case of the same set point temperature, the relationship between the respective open and stop point temperatures and the set point temperature is as follows: starting point temperature (t) of heating wireOpening device) < temperature at shutdown of damper (T)Closing device) Temperature < set value (t) < heater strip shutdown point temperature (t)Closing device) < temperature at starting point of air door (T)Opening device). After the refrigeration mode is finished, the temperature of the sensor is the temperature of a shutdown point of the air door, the temperature of the sensor is very close to the temperature of a startup point of the heating wire, if the temperature is influenced by the outside, the temperature of a storage chamber of the refrigerator can be continuously reduced, the temperature of the sensor is very easy to be lower than the temperature of the startup point of the heating wire, and therefore the heating mode is triggered to start heating after the refrigeration mode is finished. Similarly, after the heating mode is finished, the temperature of the sensor is the temperature of the heating wire shutdown point, the temperature is very close to the temperature of the air door startup point, if the temperature of the refrigerator storage room is influenced by the outside at the moment, the temperature can continue to rise, and the condition that the refrigeration mode is triggered to start refrigeration after the heating mode is finished also occurs.

In a specific implementation, the main control board obtains the current temperature in the storage chamber in real time through the temperature sensor arranged in the storage chamber.
Step S30: the main control board compares the current temperature with a refrigeration trigger temperature, starts the refrigeration device when the current temperature is not lower than the refrigeration trigger temperature, and reduces the heating trigger temperature from a first initial trigger temperature to a first target temperature;
it should be noted that, when the refrigeration trigger temperature is the starting temperature of the refrigeration device, that is, the current temperature in the storage room acquired by the main control board is not lower than the refrigeration trigger temperature, the main control board starts the refrigeration device to refrigerate the storage room; correspondingly, the heating trigger temperature is the starting temperature of the heating wire, that is, when the current temperature in the storage room acquired by the main control board is not higher than the heating trigger temperature, the main control board starts the heating wire to heat the storage room.
In a specific implementation, the main control board compares the current temperature with a refrigeration trigger temperature, and when the current temperature is not lower than the refrigeration trigger temperature, the refrigeration device is started, and the heating trigger temperature is reduced from a first initial trigger temperature to a first target temperature, for example: when the main control board detects that the current temperature is not lower than the refrigeration trigger temperature, the refrigeration device is started, in order to prevent the heating wire from being started to heat in a short time after the refrigeration device is closed and refrigeration is finished, the main control board can adjust the heating trigger temperature from a first initial trigger temperature (for example, 4 ℃) to a first target temperature (for example, 2 ℃), namely only when the current temperature of the storage chamber, which is acquired by the main control board through the temperature sensor, is not higher than the first target temperature (2 ℃), the main control board energizes the heating wire to start heating.
Step S40: and the main control board compares the current temperature with the heating trigger temperature, starts the heating wire when the current temperature is not higher than the heating trigger temperature, and increases the refrigeration trigger temperature from the second initial trigger temperature to a second target temperature.

Further, as shown in fig. 5, a second embodiment of the temperature adjusting method of the refrigerator according to the present invention is proposed based on the first embodiment of the temperature adjusting method of the refrigerator, and in this embodiment, after the step S30, the temperature adjusting method further includes:

For example: after the refrigeration cycle is completed, the main control board acquires the refrigeration trigger temperature of the refrigeration device at the moment, if the refrigeration trigger temperature is the second target temperature (10 ℃) after being increased, the refrigeration trigger temperature is restored to the preset second initial trigger temperature (8 ℃) so as to ensure the smooth opening of the subsequent refrigeration device, namely, in the subsequent process, when the main control board passes through the current temperature collected by the temperature sensor is not lower than the second initial trigger temperature (8 ℃), the refrigeration device can be started so as to reduce the temperature of the storeroom.
In this embodiment, after the main control board restores the refrigeration trigger temperature to the second initial trigger temperature, the main control board continues to acquire the current temperature in the refrigerator storage chamber detected by the temperature sensor, and starts the heating wire when the current temperature is not higher than the first target temperature.

It should be noted that, in this embodiment, the heating wire is a heating cycle from opening to closing, and when the main control board detects that after a heating cycle of the heating wire is completed, in order to ensure smooth opening of the heating wire in a subsequent heating process, the main control board may obtain a current corresponding heating trigger temperature of the heating wire, and if the current corresponding heating trigger temperature is the first target temperature after being reduced, the heating trigger temperature is restored to the first initial trigger temperature. For example: after the heating cycle is accomplished, the main control board acquires the heating trigger temperature of heater strip this moment, if this moment heating trigger temperature is first target temperature (2 ℃) after the turn-down, then with heating trigger temperature resumes to the first initial trigger temperature (4 ℃) of presetting in order to guarantee opening smoothly of follow-up heater strip, that is to say in the follow-up process, work as the main control board is passing through current temperature that temperature sensor gathered is not higher than when first initial trigger temperature (4 ℃), will start the heater strip, it is right promptly the heater strip circular telegram promotes the storeroom temperature.
In this embodiment, after the main control board restores the heating trigger temperature to the first initial trigger temperature, the main control board continues to acquire the current temperature in the refrigerator storage compartment detected by the temperature sensor, and starts the refrigeration device when the current temperature is not lower than the second target temperature.
