The present disclosure provides a control method of a refrigerator, wherein the refrigerator includes a refrigerating chamber, a freezing chamber, a compensation heater for heating the refrigerating chamber, and a compressor for synchronously refrigerating the refrigerating chamber and the freezing chamber. In general, when the compressor simultaneously cools the refrigerating chamber and the freezing chamber, the refrigerating efficiency of the refrigerating chamber is lower than that of the freezing chamber.

Fig. 1 illustrates a schematic structural diagram of a refrigerator according to an embodiment of the present disclosure.
Referring to fig. 1, in this embodiment, the refrigerator is a single-door refrigerator, and the compartments of the refrigerator include a refrigerating compartment and a freezing compartment. The refrigerator is an electronic refrigerator controlled electronically, a refrigerating system of the refrigerator is a single system, a refrigerating chamber evaporator and a freezing chamber evaporator are connected in series, and a compensating heater is arranged at the rear part of the refrigerating chamber. When the compressor is in an on state, the refrigerating chamber evaporator and the freezing chamber evaporator which are connected in series synchronously refrigerate the refrigerating chamber and the freezing chamber respectively, and the refrigerating efficiency of the refrigerating chamber is lower than that of the freezing chamber.
It should be noted that the embodiment is only an exemplary illustration, and should not limit the function and the scope of the disclosure.
Fig. 2 shows a flowchart of a control method of a refrigerator according to an embodiment of the present disclosure, which exemplarily takes a control board of the refrigerator as an execution main body, and with reference to fig. 2, the method includes:
step S110, monitoring the temperature of a refrigerating chamber of the refrigerating chamber;
step S120, monitoring the working state of the compressor and the working mode of the compressor, wherein the working state comprises an opening state and a closing state, and the working mode comprises a quick-freezing mode and a non-quick-freezing mode;
step S130, when it is detected that the compressor is in an on state and in a quick-freeze mode, if it is detected that the temperature of the refrigerating chamber is lower than or equal to a preset first temperature threshold, the compensation heater is controlled to be in an on state, and if it is detected that the temperature of the refrigerating chamber is lower than or equal to a preset second temperature threshold, the compressor is controlled to be in an off state and in the quick-freeze mode, wherein the first temperature threshold is higher than the second temperature threshold.
In the embodiment of the disclosure, in the process of powering on the refrigerator, the control board monitors the temperature of the refrigerating chamber, the working state of the compressor and the working mode of the compressor. The working state of the compressor comprises an opening state and a closing state, and the working mode of the compressor comprises a quick-freezing mode and a non-quick-freezing mode. There are four possible combinations between operating states and operating modes: the compressor is in an open state and in a quick-freezing mode, the compressor is in an open state and in a non-quick-freezing mode, the compressor is in a closed state and in a quick-freezing mode, and the compressor is in a closed state and in a non-quick-freezing mode. Compared with a non-quick-freezing mode, the refrigerating efficiency in the quick-freezing mode is higher, namely, the temperature drop speed of the refrigerating chamber and the freezing chamber in the quick-freezing mode is higher.
In the embodiment of the disclosure, when the compressor is detected to be in an on state and in a quick-freezing mode, the control board controls the compensation heater to be switched on or off according to the temperature of the refrigerating chamber and the height of the first temperature threshold value, and controls whether the compressor is switched off or not according to the temperature of the refrigerating chamber and the height of the second temperature threshold value. Specifically, the temperature of the refrigerating chamber is obtained and compared with a preset first temperature threshold and a preset second temperature threshold respectively, wherein the first temperature threshold is higher than the second temperature threshold. And controlling the compensating heater to be in a switch-on state if the temperature of the refrigerating chamber is detected to be lower than or equal to the first temperature threshold, and controlling the compressor to be in a switch-off state and be in a quick-freezing mode if the temperature of the refrigerating chamber is detected to be lower than or equal to the second temperature threshold.
For example: the target temperature range of the refrigerating chamber is 1-3 ℃, and in the quick-freezing mode, if the temperature of the refrigerating chamber is detected to be lower than or equal to 1 ℃, the control panel must control the compressor to be in a closed state so as to prevent the temperature of the refrigerating chamber from being too low, and if the temperature of the refrigerating chamber is detected to be higher than 3 ℃, the control panel must control the compressor to be in an open state so as to enable the refrigerating chamber to refrigerate sufficiently. The first temperature threshold is set to 3 deg.c and the second temperature threshold is set to 1 deg.c. When the compressor is detected to be in an opening state and in a quick-freezing mode, if the temperature of the refrigerating chamber is lower than or equal to 3 ℃, the control panel controls the compensation heater to be in a switch-on state, so that the compensation heater heats the refrigerating chamber; after the compensation heater is controlled to be in a connection state, the control panel controls the compressor to be continuously kept in a starting state and in a quick-freezing mode under the condition that the temperature of the refrigerating chamber is still higher than 1 ℃; and turning off the compressor until the temperature of the refrigerating chamber is detected to be reduced to 1 ℃ or below 1 ℃, and controlling the compressor to be in a turn-off state and in a quick-freezing mode.
Therefore, in the embodiment of the disclosure, when the compressor is in an on state and in a quick-freezing mode, the compensation heater is turned on in advance before the temperature of the refrigerating chamber is reduced to a temperature threshold value capable of triggering the compressor to be turned off, so that the situation that the local area of the refrigerating chamber is cooled to an excessively low temperature by the compressor with high refrigerating efficiency in the quick-freezing mode is avoided (for example, the lowest target temperature of the refrigerating chamber is 1 ℃, and if the temperature of the refrigerating chamber is reduced to 1 ℃, the compensation heater is turned on, the compressor in the quick-freezing mode may be caused to refrigerate the bottom area of the refrigerating chamber to 0; in addition, the compensation heater is switched on in advance in the quick-freezing mode, so that the falling speed of the temperature of the refrigerating chamber is slowed down, the time for reducing the temperature of the refrigerating chamber to the temperature threshold value capable of triggering the compressor to be turned off is prolonged, the time for refrigerating the refrigerating chamber is prolonged, the refrigerating effect of the refrigerating chamber is improved, and the balance of the synchronous refrigerating chamber and the refrigerating chamber is comprehensively improved.
In an embodiment, the method further comprises: when the compressor is detected to be in an opening state and in a quick-freezing mode, if the temperature of the refrigerating chamber is detected to be higher than the first temperature threshold value, the compensating heater is controlled to be in a disconnection state.
In this embodiment, when the compressor is detected to be in the on state and in the quick-freezing mode, the control board controls the compensation heater to be in the off state if the temperature of the refrigerating chamber is detected to be higher than the first temperature threshold.
For example: the target temperature range of the refrigerating compartment is 1 ℃ to 3 ℃, and the first temperature threshold value is set to 3 ℃. When the control board detects that the compressor is in an opening state and in a quick-freezing mode, if the temperature of the refrigerating chamber is higher than 3 ℃, the compensation heater is controlled to be in a disconnection state, and the compensation heater cannot heat the refrigerating chamber.
The embodiment has the advantages that in the quick-freezing mode, the compensating heater is controlled to be in the off state when the temperature of the refrigerating chamber is still higher than the first temperature threshold value, the operation of the compensating heater under the condition that the refrigerating chamber does not need to be heated is avoided, and power resources are saved.
In an embodiment, the method further comprises: and when the compressor is detected to be in an opening state and in a non-quick-freezing mode, controlling the compensating heater to be in a disconnection state.
In this embodiment, the control board controls the compensation heater to be in the off state when the compressor is detected to be in the on state and in the non-quick-freezing mode. Specifically, in the non-shock freezing mode, the compensation heater is primarily used to trigger the compressor into an on state. Therefore, in the non-quick-freezing mode, if the compressor is already in the on state, the compensation heater does not need to be switched on again.
This embodiment has an advantage in that in the non-rapid freezing mode, it is not necessary to switch on the compensating heater again if the compressor is already in the on state, and power resources are saved by controlling the compensating heater to be in the off state in this case.
In an embodiment, the method further comprises:
monitoring the ambient temperature of the environment where the refrigerator is located;
when the compressor is detected to be in a closed state, if the detected ambient temperature is lower than or equal to a preset third temperature threshold value, the compensation heater is controlled to be in an on state, or if the ambient temperature is higher than the third temperature threshold value, the compensation heater is controlled to be in an off state.
In this embodiment, during the power-on process of the refrigerator, the control board monitors the ambient temperature of the environment where the refrigerator is located, and when the compressor is detected to be in the off state, the compensation heater is controlled to be switched on or off according to the ambient temperature and the third temperature threshold. Specifically, when the compressor is detected to be in the off state, the control board controls the compensation heater to be in the on state if the detected ambient temperature is lower than or equal to a preset third temperature threshold, or controls the compensation heater to be in the off state if the detected ambient temperature is higher than the third temperature threshold.
For example: the preset third temperature threshold is 14 ℃. When the control board detects that the compressor is in a closed state, the compensating heater is controlled to be in a switch-on state if the ambient temperature is lower than or equal to 14 ℃, or the compensating heater is controlled to be in a switch-off state if the ambient temperature is higher than 14 ℃.
This embodiment has the advantage that when the ambient temperature is low, the temperature of the refrigerating chamber is relatively low, and the problem that the compressor cannot be automatically turned on or the turning-on time is insufficient may occur, so that the refrigerating chamber cannot be sufficiently cooled. In this way, the compensation heater is turned on at low ambient temperatures, so that the compressor can more fully refrigerate the freezer compartment.
In an embodiment, the method further comprises: and when an instruction for entering the quick-freezing mode is received, controlling the compressor to be in an opening state and in the quick-freezing mode.
In the embodiment, as long as the instruction of entering the quick-freezing mode is received, no matter whether the compressor is originally in the opening state or in the closing state, the control panel controls the compressor to be in the opening state and in the quick-freezing mode.
Specifically, the user can send a quick-freeze mode instruction to the control panel through a specific operation. For example: the mode switching knob in the refrigerator is rotated, so that the control panel receives an instruction of entering a quick-freezing mode; or, the mode switching button on the refrigerator remote controller is clicked, so that the control panel receives an instruction of entering the quick-freezing mode.
In an embodiment, the method further comprises:
when the compressor is detected to be in the closed state and in the quick-freezing mode, if the temperature of the refrigerating chamber is detected to be higher than or equal to a preset fourth temperature threshold value, the compressor is controlled to be in the open state and in the quick-freezing mode, or if the temperature of the refrigerating chamber is detected to be lower than the fourth temperature threshold value, the compressor is controlled to be in the closed state and in the quick-freezing mode continuously, wherein the fourth temperature threshold value is higher than the second temperature threshold value.
In this embodiment, when the control board detects that the compressor is in the off state and in the quick-freezing mode, whether the compressor is on or not is controlled according to the temperature of the refrigerating chamber and the level of a fourth temperature threshold, wherein the fourth temperature threshold is higher than a second temperature threshold for controlling whether the compressor is off or not when the compressor is in the on state and in the quick-freezing mode.
Specifically, when the compressor is detected to be in the off state and in the quick-freezing mode, if the temperature of the refrigerating chamber is detected to be higher than or equal to a fourth temperature threshold value, the control panel controls the compressor to be in the on state and in the quick-freezing mode, or if the temperature of the refrigerating chamber is detected to be lower than the fourth temperature threshold value, the control panel controls the compressor to be continuously in the off state and in the quick-freezing mode.
For example: the target temperature range of the refrigerating compartment is 1 to 3 deg.c, the fourth temperature threshold value is set to 3 deg.c, and the second temperature threshold value is set to 1 deg.c. When the compressor is detected to be in a closed state and in a quick-freezing mode, if the temperature of the refrigerating chamber is detected to be higher than or equal to 3 ℃, the control panel controls the compressor to be started, so that the compressor is in a starting state and in the quick-freezing mode; or if the temperature of the refrigerating chamber is detected to be lower than 3 ℃, the control panel controls the compressor to be in the closed state continuously and in the quick-freezing mode.
An advantage of this embodiment is that in this way the temperature in the refrigerating compartment is neither reduced too low, while at the same time the temperature in the freezer compartment is also sufficiently refrigerated.
In an embodiment, the first temperature threshold is less than the fourth temperature threshold.
In this embodiment, in the quick-freeze mode, the first temperature threshold for controlling the on/off of the compensation heater is between the fourth temperature threshold for controlling the on/off of the compressor and the second temperature threshold.
For example: the target temperature range of the refrigerating compartment is 1 to 3 deg.c, the fourth temperature threshold value is set to 3 deg.c, the first temperature threshold value is set to 2 deg.c, and the second temperature threshold value is set to 1 deg.c. When the compressor is detected to be in an opening state and in a quick-freezing mode, if the temperature of the refrigerating chamber is lower than or equal to 2 ℃, the control panel controls the compensation heater to be in a switch-on state, so that the compensation heater heats the refrigerating chamber; after the compensation heater is controlled to be in a connection state, the control panel controls the compressor to be continuously kept in a starting state and in a quick-freezing mode under the condition that the temperature of the refrigerating chamber is still higher than 1 ℃; until the temperature of the refrigerating chamber is detected to be reduced to 1 ℃ or below 1 ℃, the control panel closes the compressor, and controls the compressor to be in a closed state and in a quick-freezing mode; when the compressor is detected to be in the closed state and in the quick-freezing mode, if the temperature of the refrigerating chamber is detected to be lower than 3 ℃, the compressor is controlled to be in the closed state and in the quick-freezing mode continuously; and starting the compressor by the control panel until the temperature of the refrigerating chamber is detected to be higher than 3 ℃ or higher than 3 ℃, and controlling the compressor to be in an opening state and in a quick-freezing mode.
This embodiment has an advantage in that by setting the first temperature threshold value to be intermediate between the fourth temperature threshold value and the second temperature threshold value, the refrigerating chamber temperature is not lowered to the second temperature threshold value too quickly to some extent, and the refrigerating effect of the freezing chamber is improved to some extent.
In an embodiment, the first temperature threshold is equal to the fourth temperature threshold.
In this embodiment, in the quick-freeze mode, the first temperature threshold for controlling the switching on and off of the compensation heater is equal to the fourth temperature threshold for controlling the switching on of the compressor.
For example: the target temperature range of the refrigerating chamber is 1 ℃ to 3 ℃, the first temperature threshold value and the fourth temperature threshold value are both set to 3 ℃, and the second temperature threshold value is set to 1 ℃. When the compressor is detected to be in an opening state and in a quick-freezing mode, if the temperature of the refrigerating chamber is lower than or equal to 3 ℃, the control panel controls the compensation heater to be in a switch-on state, so that the compensation heater heats the refrigerating chamber; after the compensation heater is controlled to be in a connection state, the control panel controls the compressor to be continuously kept in a starting state and in a quick-freezing mode under the condition that the temperature of the refrigerating chamber is still higher than 1 ℃; until the temperature of the refrigerating chamber is detected to be reduced to 1 ℃ or below 1 ℃, the control panel closes the compressor, and controls the compressor to be in a closed state and in a quick-freezing mode; when the compressor is detected to be in the closed state and in the quick-freezing mode, if the temperature of the refrigerating chamber is detected to be lower than 3 ℃, the compressor is controlled to be in the closed state and in the quick-freezing mode continuously; and starting the compressor by the control panel until the temperature of the refrigerating chamber is detected to be increased to 3 ℃ or above 3 ℃, and controlling the compressor to be in an opening state and in a quick-freezing mode.
This embodiment has an advantage in that by setting the first temperature threshold equal to the fourth temperature threshold, the refrigerating compartment temperature is maximally prevented from being lowered to the second temperature threshold too quickly, and the refrigerating effect of the freezing compartment is maximally improved, while ensuring the refrigerating efficiency of the refrigerating compartment.
In an embodiment, the method further comprises:
determining a current refrigeration gear of the refrigerator;
and according to the refrigerating chamber temperature intervals which are respectively configured for each refrigerating gear in advance, determining a second temperature threshold corresponding to the current refrigerating gear and a fourth temperature threshold corresponding to the current refrigerating gear.
In this embodiment, the refrigerator has a plurality of refrigeration gears, and different refrigeration gears are respectively configured with corresponding refrigerating chamber temperature intervals. And the control panel determines a second temperature threshold corresponding to the current refrigeration gear and a fourth temperature threshold corresponding to the current refrigeration gear according to the refrigerating chamber temperature interval corresponding to the current refrigeration gear. Specifically, the user can adjust the refrigeration gear by rotating a knob on the refrigerator or clicking a button on the remote controller.
For example: the refrigerator has 3 refrigeration gears, 2 grades, 3 grades and 4 grades respectively. The refrigerating chamber temperature interval configured in the 2 nd gear is [3,5], the refrigerating chamber temperature interval configured in the 3 rd gear is [2,4], and the refrigerating chamber temperature interval configured in the 4 th gear is [1,3 ]. When the current refrigeration gear is the 2 gear, determining the second temperature threshold as 3 ℃, and determining the fourth temperature threshold as 5 ℃; when the current refrigeration gear is 3, determining the second temperature threshold value as 2 ℃, and determining the fourth temperature threshold value as 4 ℃; and when the current refrigeration gear is 4 gears, determining the second temperature threshold value as 1 ℃, and determining the fourth temperature threshold value as 3 ℃.
The embodiment has the advantage that the refrigerator can flexibly meet the requirements of users by setting a plurality of refrigeration gears.
In an embodiment, the method further comprises:
monitoring the duration of the compressor in the quick-freeze mode;
and when the duration is detected to be higher than a preset duration threshold value, controlling the compressor to be in a non-quick-freezing mode.
In the embodiment, the control panel detects the duration of the compressor in the quick-freezing mode, and when the duration is higher than a preset duration threshold value, the compressor is quitted from the quick-freezing mode and is controlled to be in the non-quick-freezing mode.
For example: the preset duration is 52h, when the duration that the compressor is in the quick-freezing mode is detected to be longer than 52h, the quick-freezing mode is exited, and the compressor is controlled to be in the non-quick-freezing mode.
The embodiment has the advantages that the quick-freezing mode is automatically exited according to the duration of the quick-freezing mode, so that a large amount of power consumption is avoided, and power resources are saved.
Fig. 3 illustrates a flowchart of controlling a compensating heater in a control method of a refrigerator according to an embodiment of the present disclosure.
In this embodiment, the preset first temperature threshold for controlling the on/off of the compensation heater when the compressor is in the on state and in the quick-freeze mode is 3 ℃, and the preset third temperature threshold for controlling the on/off of the compensation heater when the compressor is in the off state is 14 ℃. The temperature of the refrigerating chamber is denoted as Tr and the ambient temperature is denoted as Te.
The control board determines whether the compressor is on. If so, determining whether the compressor is in a quick-freezing mode. If the quick-freezing mode is started, determining whether Tr is less than or equal to 3 ℃. If the device is started and is in a quick-freezing mode and Tr is less than or equal to 3 ℃, the compensating heater is switched on; if the device is started and is in a quick-freezing mode and Tr is more than 3 ℃, the compensating heater is switched off; if the mode is turned on and not the quick-freeze mode, the compensation heater is turned off.
