A control method of the refrigerator 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 3.
As shown in fig. 1 and 2, a refrigerator 100 according to an embodiment of the present invention includes: the refrigerator includes a compressor 1, a condenser 2, a refrigerating flow path 3, a freezing flow path 4, a refrigerating fan 33, a freezing fan 43, a first temperature sensor 5, and a second temperature sensor 6.
Specifically, the compressor 1 has an exhaust port 11 and a return port 12, and one end of the condenser 2 is connected to the exhaust port 11 of the compressor 1. One end of the refrigerating flow path 3 and one end of the freezing flow path 4 are connected to the other end of the condenser 2 through an electromagnetic valve 7, a first throttle device 31 and a refrigerating evaporator 32 for refrigerating a refrigerating chamber 34 of the refrigerator 100 are connected in series to the refrigerating flow path 3, a second throttle device 41 and a freezing evaporator 42 for refrigerating a freezing chamber 44 of the refrigerator 100 are connected in series to the freezing flow path 4, the other end of the refrigerating flow path 3 is connected between the freezing evaporator 42 and the second throttle device 41, and the other end of the freezing flow path 4 is connected to the return air port 12. The refrigerating fan 33 is disposed adjacent to the refrigerating evaporator 32 to blow cold air generated by the refrigerating evaporator 32 to the refrigerating compartment 34, and the freezing fan 43 is disposed adjacent to the freezing evaporator 42 to blow cold air generated by the freezing evaporator 42 to the freezing compartment 44. The first temperature sensor 5 is provided in the refrigerating compartment 34, and the second temperature sensor 6 is provided in the freezing compartment 44.
The control method comprises the following steps: when the first temperature sensor 5 detects that the temperature of the refrigerating chamber 34 reaches the preset refrigerating temperature and the second temperature sensor 6 detects that the temperature of the freezing chamber 44 is lower than the first preset freezing temperature, namely when the refrigerating chamber 34 requests cooling and the freezing chamber 44 does not request cooling, one end of the refrigerating flow path 3 is communicated with the other end of the condenser 2, one end of the freezing flow path 4 is disconnected with the other end of the condenser 2, the refrigerating fan 33 is started, and the freezing fan 43 stops operating until the temperature of the refrigerating chamber 34 detected by the first temperature sensor 5 and the temperature of the freezing chamber 44 detected by the second temperature sensor 6 do not meet the above conditions. The refrigerant passes through the refrigerating evaporator 32 and the freezing evaporator 42, and only the refrigerating compartment 34 cools and the freezing compartment 44 does not cool because the freezing fan 43 is not turned on. Therefore, the simultaneous opening of the refrigerating fan 33 and the freezing fan 43, which causes the loss of fan energy and the loss of system operation energy due to the overhigh system evaporation temperature, can be avoided. In addition, the temperature of the freezing chamber 44 can be detected by the second temperature sensor 6, and the temperature of the freezing chamber 44 can be prevented from increasing.
When the first temperature sensor 5 detects that the temperature of the refrigerating chamber 34 reaches the preset refrigerating temperature and the second temperature sensor 6 detects that the temperature of the freezing chamber 44 reaches the first preset freezing temperature, namely when the refrigerating chamber 34 requests refrigeration and the freezing chamber 44 requests refrigeration, one end of the refrigerating flow path 3 is communicated with the other end of the condenser 2, one end of the freezing flow path 4 is disconnected with the other end of the condenser 2, the refrigerating fan 33 and the freezing fan 43 are both started, and both the refrigerating chamber 34 and the freezing chamber 44 refrigerate. When the second temperature sensor 6 detects that the temperature of the freezing compartment 44 is lower than the second preset freezing temperature, the operation of the freezing fan 43 is stopped, the freezing compartment 44 stops cooling, and the refrigerating compartment 34 continues cooling until the temperature of the refrigerating compartment 34 detected by the first temperature sensor 5 and the temperature of the freezing compartment 44 detected by the second temperature sensor 6 do not satisfy the above conditions. Wherein the second preset freezing temperature is lower than the first preset freezing temperature. Therefore, the loss of fan energy and the loss of system operation energy consumption caused by the fact that the refrigerating fan 33 and the freezing fan 43 are simultaneously started due to overhigh system evaporation temperature can be avoided, and the situation that the freezing chamber 44 is not refrigerated (namely, the freezing fan 43 is not started for a long time) caused by the long-time starting of the refrigerating chamber 34 when a large amount of food is placed in the refrigerating chamber 34 can be avoided.
When the first temperature sensor 5 detects that the temperature of the refrigerating chamber 34 is lower than the preset refrigerating temperature and the second temperature sensor 6 detects that the temperature of the freezing chamber 44 is lower than the first preset freezing temperature, namely when neither the refrigerating chamber 34 nor the freezing chamber 44 requests refrigeration, one end of the refrigerating flow path 3 is disconnected from the other end of the condenser 2, one end of the freezing flow path 4 is communicated with the other end of the condenser 2, the refrigerating fan 33 and the freezing fan 43 stop running, and neither the refrigerating chamber 34 nor the freezing chamber 44 refrigerates until the temperature of the refrigerating chamber 34 detected by the first temperature sensor 5 and the temperature of the freezing chamber 44 detected by the second temperature sensor 6 do not meet the above conditions.
When the first temperature sensor 5 detects that the temperature of the refrigerating chamber 34 is lower than the preset refrigerating temperature and the second temperature sensor 6 detects that the temperature of the freezing chamber 44 reaches the first preset freezing temperature, namely when the refrigerating chamber 34 does not request cooling and the freezing chamber 44 requests cooling, one end of the refrigerating flow path 3 is disconnected from the other end of the condenser 2, one end of the freezing flow path 4 is communicated with the other end of the condenser 2, the refrigerating fan 33 stops operating, the freezing fan 43 is started, the refrigerating chamber 34 does not cool, and the freezing chamber 44 cools until the temperature of the refrigerating chamber 34 detected by the first temperature sensor 5 and the temperature of the freezing chamber 44 detected by the second temperature sensor 6 do not meet the above conditions.
According to the control method of the refrigerator 100 of the embodiment of the invention, when the refrigerating chamber 34 requests refrigeration and the freezing chamber 44 does not request refrigeration, one end of the refrigerating flow path 3 is communicated with the other end of the condenser 2, one end of the freezing flow path 4 is disconnected with the other end of the condenser 2, the refrigerating fan 33 is started, and the freezing fan 43 stops running, so that the loss of fan energy and the loss of system running energy caused by the fact that the refrigerating fan 33 and the freezing fan 43 are started simultaneously due to overhigh system evaporation temperature can be avoided.
When the refrigerating chamber 34 requests cooling and the freezing chamber 44 requests cooling, one end of the refrigerating flow path 3 is communicated with the other end of the condenser 2, one end of the freezing flow path 4 is disconnected from the other end of the condenser 2, the refrigerating fan 33 and the freezing fan 43 are both turned on, both the refrigerating chamber 34 and the freezing chamber 44 cool, and when the second temperature sensor 6 detects that the temperature of the freezing chamber 44 is lower than the second preset freezing temperature, the freezing fan 43 stops operating, the freezing chamber 44 stops cooling, and the refrigerating chamber 34 continues cooling. Not only can the fan energy loss and the system operation energy loss caused by the overhigh system evaporation temperature when the refrigerating fan 33 and the freezing fan 43 are started at the same time be avoided, but also the condition that the freezing chamber 44 is not refrigerated caused by the long-time start of the refrigerating chamber 34 when a large amount of food is placed in the refrigerating chamber 34 can be avoided.
In addition, the control method can effectively ensure the temperature of the refrigerating chamber 34 and the freezing chamber 44, so as to achieve the purposes of energy conservation and accurate temperature control.
In some embodiments of the present invention, the difference between the second preset freezing temperature and the first preset freezing temperature is t, and t satisfies: t is more than or equal to 3 ℃ and less than or equal to 7 ℃. Therefore, the temperature of the freezing compartment 44 can be ensured to be below the first preset freezing temperature for a certain time, the freezing compartment 44 is prevented from being frequently switched between a refrigerating state and a non-refrigerating state, the freezing compartment 44 can be prevented from being in a refrigerating state for a long time, and the energy loss of a fan and the energy loss of system operation are favorably saved.
Further, t is 5 ℃. Therefore, the temperature of the freezing compartment 44 can be ensured to be below the first preset freezing temperature for a certain time, the freezing compartment 44 is prevented from being frequently switched between a refrigerating state and a non-refrigerating state, the freezing compartment 44 can be prevented from being in a refrigerating state for a long time, and the energy loss of a fan and the energy loss of system operation are favorably saved.
In some embodiments of the invention, the first predetermined freezing temperature is-15 ℃. When the temperature in the freezing compartment 44 is below-15 ℃, the quality of the articles stored in the freezing compartment 44 can be ensured, and the articles stored in the freezing compartment 44 are prevented from being damaged, and when the temperature in the freezing compartment 44 is higher than-15 ℃, the freezing compartment 44 requests refrigeration, and the articles in the freezing compartment 44 are prevented from being damaged due to overhigh temperature.
In some embodiments of the present invention, at least one of the first throttling means 31 and the second throttling means 41 is a capillary tube. For example, in the example shown in fig. 1, the first throttle device 31 and the second throttle device 41 are both capillary tubes. Of course, the present invention is not limited thereto, and at least one of the first throttle device 31 and the second throttle device 41 is an electronic expansion valve. Thereby increasing the variety of the structure of the refrigerator 100.
In some embodiments of the present invention, as shown in fig. 1, a dryer 8 is disposed between the other end of the condenser 2 and the solenoid valve 7, so as to improve the heat exchange effect of the refrigerating evaporator 32 or the freezing evaporator 42, and thus improve the cooling effect of the refrigerating compartment 34 or the freezing compartment 44.
In some embodiments of the present invention, as shown in fig. 1, a dew prevention pipe 9 is disposed between the other end of the condenser 2 and the solenoid valve 7, and the dew prevention pipe 9 is disposed at an edge of the door body of the refrigerator 100. Because the edge of the door body of the refrigerator 100 can generate water drops in wet weather, the anti-dew pipe 9 is designed on the edge of the door body of the refrigerator 100 and is connected with the condenser 2, and in the refrigerating process of the refrigerator 100, high-pressure gas refrigerant can flow through the pipe and generate heat so as to prevent the water drops from generating and play a role in preventing dew.
In some embodiments of the present invention, as shown in FIG. 2, the refrigerated compartment 34 and the freezer compartment 44 are arranged side-by-side in a horizontal direction. The refrigerator 100 may be a side-by-side refrigerator 100. Of course, the present invention is not limited thereto, and the refrigerating compartment 34 and the freezing compartment 44 may be disposed side by side in a vertical direction.

The refrigerating compartment 34 is provided with a refrigerating air port, the freezing compartment 44 is provided with a freezing air port, when the refrigerating compartment 34 requests refrigeration, the refrigerating fan 33 operates, and cold air enters the refrigerating compartment 34 through the refrigerating air port to circulate and then returns to the refrigerating evaporator 32 through the refrigerating air port. When the freezing compartment 44 requests cooling, the refrigerating fan 33 is operated, and cold air enters the freezing compartment 44 through the freezing air opening to circulate and then returns to the refrigerating evaporator 32 through the refrigerating air opening.
The refrigerator 100 according to the embodiment of the present invention is controlled by the above control method.
According to the refrigerator 100 of the embodiment of the invention, when the refrigerating chamber 34 requests refrigeration and the freezing chamber 44 does not request refrigeration, one end of the refrigerating flow path 3 is communicated with the other end of the condenser 2, one end of the freezing flow path 4 is disconnected with the other end of the condenser 2, the refrigerating fan 33 is started, and the freezing fan 43 stops running, so that the loss of fan energy and the loss of system running energy caused by the fact that the refrigerating fan 33 and the freezing fan 43 are started simultaneously due to overhigh system evaporation temperature can be avoided.
When the refrigerating chamber 34 requests cooling and the freezing chamber 44 requests cooling, one end of the refrigerating flow path 3 is communicated with the other end of the condenser 2, one end of the freezing flow path 4 is disconnected from the other end of the condenser 2, the refrigerating fan 33 and the freezing fan 43 are both turned on, both the refrigerating chamber 34 and the freezing chamber 44 cool, and when the second temperature sensor 6 detects that the temperature of the freezing chamber 44 is lower than the second preset freezing temperature, the freezing fan 43 stops operating, the freezing chamber 44 stops cooling, and the refrigerating chamber 34 continues cooling. Not only can the fan energy loss and the system operation energy loss caused by the overhigh system evaporation temperature when the refrigerating fan 33 and the freezing fan 43 are started at the same time be avoided, but also the condition that the freezing chamber 44 is not refrigerated caused by the long-time start of the refrigerating chamber 34 when a large amount of food is placed in the refrigerating chamber 34 can be avoided. In addition, the temperature of the refrigerating chamber 34 and the freezing chamber 44 can be effectively ensured, so that the purposes of energy conservation and accurate temperature control are achieved.
