a detected temperature of a surface of the first evaporator.
And judging whether the temperature of the surface of the first evaporator is at the condensation temperature or not.
If so, circulating the air in the first storage room between the first storage room and the cooling room so as to enable the air in the first storage room to pass through the surface of the first evaporator. If not, starting a heating device to heat the first evaporator until the temperature of the surface of the first evaporator is at the condensation temperature.
Optionally, when the humidity of the first storage compartment is higher than or equal to a first preset humidity value and the first evaporator cools the first storage compartment, the first evaporator is stopped from cooling the first refrigeration compartment.
Optionally, the refrigerator further comprises a second storage chamber, a compressor, a valve and a second evaporator, wherein the second evaporator is used for refrigerating the second storage chamber. When the first evaporator needs to be stopped, the first evaporator is stopped by the valve and the second evaporator so as to enable the compressor to continue to work.
Optionally, the heating device is an electric heating device.
Optionally, the first storage compartment is a refrigerating compartment, and the second storage compartment is a freezing compartment. The target refrigerating temperature of the refrigerating chamber is 2-8 ℃, and the target refrigerating temperature of the freezing chamber is-16-22 ℃.
Optionally, the condensation temperature is 0 to 0.5 degrees celsius.
Optionally, when the first evaporator needs to be stopped, stopping the first evaporator by using the valve and the second evaporator, so that the compressor continues to operate specifically includes: when the first evaporator needs to be stopped and the second evaporator is in a working state, the first evaporator is stopped by the valve. And/or when the first evaporator needs to be stopped and the second evaporator is in a stop state, stopping the first evaporator by using the valve and starting the second evaporator.

According to the control method of the refrigerator and the refrigerator, the surface temperature of the first evaporator is always at the condensation temperature, the condensation temperature is greater than or equal to 0 ℃, the condensation temperature enables moisture in the air passing through the first evaporator to be condensed and not to frost, the air is circulated between the first storage room and the cooling room, so that water vapor in the air in the first storage room is condensed into water drops on the surface of the first evaporator, and the humidity of the air in the first storage room is further reduced. The arrangement can reduce or prevent the first evaporator of the refrigerator from frosting during working, prolongs the defrosting time interval, reduces the power consumption of the refrigerator and improves the refrigerating effect of the refrigerator. In particular, the manner of condensing water droplets on the surface of the first evaporator without frosting ensures that the first evaporator does not frost or has a small amount of frosting during the process of dehumidifying the air in the first storage compartment without defrosting the evaporator due to dehumidification.
Furthermore, according to the control method of the refrigerator and the refrigerator, the temperature of the surface of the first evaporator is always at the condensation temperature by heating the first evaporator, and compared with the arrangement that the temperature of the surface of the first evaporator is always at the condensation temperature by adopting a four-way valve reversing mode, the temperature of the first evaporator is more accurately and simply controlled by the refrigerator, and continuous defrosting can be realized.

Fig. 1 is a schematic view of a refrigerator according to an embodiment of the present invention, and as shown in fig. 1, an embodiment of the present invention provides a refrigerator 10 including a first storage compartment 11, a cooling compartment 13, and a first evaporator 134. The first storage compartment 11 and the cooling compartment 13 are independently arranged adjacent to each other, and a vent hole is formed between the first storage compartment 11 and the cooling compartment 13 in a penetrating manner, so that air in the first storage compartment 11 can circulate between the first storage compartment 11 and the cooling compartment 13. In other embodiments, the first storage compartment 11 and the cooling compartment 13 are independent and not adjacent to each other, and the first storage compartment 11 and the cooling compartment 13 are communicated through a circulating air duct. The first storage compartment 11 may store food items. The first evaporator 134 is disposed in the cooling chamber 13. The first evaporator 134 is used for exchanging heat with air, so as to refrigerate the first storage compartment 11. Referring to fig. 2, an embodiment of the present invention further provides a control method of a refrigerator, which may control the refrigerator 10 of the above embodiment, and the control method includes:
step S301 detects the humidity of the air in the first storage compartment 11.
Step S302, when the humidity of the air in the first storage compartment 11 is higher than or equal to a first preset humidity value, the temperature of the surface of the first evaporator 134 is at the condensation temperature. The condensation temperature is greater than or equal to 0 degrees celsius, and the condensation temperature is such that moisture in the air passing through the first evaporator 134 is condensed and does not frost.
Step S303, the air in the first storage compartment 11 is circulated between the first storage compartment 11 and the cooling chamber 13, so that the air in the first storage compartment 11 passes through the first evaporator 134 until the humidity of the air in the first storage compartment 11 is lower than or equal to a second preset humidity value.
In the control method of the refrigerator of the embodiment, the temperature of the surface of the first evaporator 134 is always at the condensation temperature, and the air in the first storage compartment 11 is circulated between the first storage compartment 11 and the cooling chamber 13, so that the water vapor in the air is condensed into water drops on the surface of the first evaporator 134, and the humidity of the air in the first storage compartment 11 is reduced. This arrangement prevents the first evaporator 134 of the refrigerator 10 from frosting during operation and enhances the cooling effect of the refrigerator 10. In particular, the use of water droplets condensed on the surface of first evaporator 134 without frost ensures that first evaporator 134 does not frost or frost in a small amount during dehumidification of the air in first compartment 11, without defrosting first evaporator 134 for dehumidification.
Referring to fig. 3, in some embodiments of the present invention, the control method of the refrigerator includes a step S402 of stopping the first evaporator 134 from cooling the first storage compartment 11 when the humidity of the first storage compartment 11 is higher than or equal to a first preset humidity value and when the first evaporator 134 cools the first storage compartment 11. That is, when the first evaporator 134 is operating, the first evaporator 134 can be stopped first, so that the first evaporator 134 does not continue to cool down or provide cooling energy, which helps to reduce the heat energy required for increasing the temperature of the first evaporator 134.
In some embodiments of the present invention, the specific working process of bringing the temperature of the surface of the first evaporator for refrigerating the first storage compartment to the condensation temperature is as follows:
in step S403, the temperature of the surface of the first evaporator 134 is detected.
In step S404, it is determined whether the temperature of the surface of the first evaporator 134 is at the condensation temperature. Otherwise, step S405 is executed, and if so, step S303 is executed.
In step S405, the heating device is turned on to heat the first evaporator 134, and the process returns to step S403. That is, the heating device is turned on to heat the first evaporator 134 until the temperature of the surface of the first evaporator 134 is at the condensation temperature, and then step S303 is performed.
In some embodiments of the present invention, the method for controlling a refrigerator further includes, after the humidity in the first storage compartment is lower than or equal to a second preset humidity value: the first evaporator 134 is activated to cool the first compartment 11 and the air in the first compartment 11 is circulated between the first compartment 11 and the cooling chamber 13 such that the air in the first compartment passes through the first evaporator. In this embodiment, if the heating device is in operation, the heating device may be stopped while the first evaporator 134 is enabled to start cooling. Under the general condition, when the article just are put into the storing room, humidity is bigger, and the standing horse refrigerates article after accomplishing the dehumidification, has fine fresh-keeping effect. Referring to fig. 1 and 4, in some embodiments of the present invention, the refrigerator 10 further includes a second storage compartment 12, another cooling compartment 14, a compressor 131, a condenser 132, a valve 133, and a second evaporator 135. The second storage compartment 12 is independently arranged from the first storage compartment 11, the second storage compartment 12 is independently arranged adjacent to the other cooling compartment 14, and a vent hole is arranged between the second storage compartment 12 and the other cooling compartment 14 in a penetrating manner, so that air in the second storage compartment 12 can circulate between the second storage compartment 12 and the other cooling compartment 14. The second evaporator 135 is disposed in the other cooling chamber 14. Of course, the second storage compartment 12 can be communicated with the other cooling compartment 14 at a longer distance through an air duct, or the second evaporator 135 can cool the second storage compartment 12 by direct cooling. The second storage compartment 12 may store food items.
One end of the compressor 131 is connected to one end of the condenser 132, and the other end of the compressor 131 is connected to the first evaporator 134 and the second evaporator 135. The other end of the condenser 132 is connected to one end of a valve 133. The other end of the valve 133 is connected to the first evaporator 134 and the second evaporator 135, and the valve 133 may be a three-way valve, which can change the flow direction of the refrigerant. The above and the like constitute the refrigerating system of the refrigerator 10 such that the second evaporator 135 is connected in parallel with the first evaporator 134.
When it is necessary to stop the operation of the first evaporator 134 and when the second evaporator 135 is in an operating state, the operation of the first evaporator 134 is stopped by the valve 133. When it is necessary to stop the operation of the first evaporator 134 and when the second evaporator 135 is in a stop state, the first evaporator 134 is stopped by the valve 133 and the second evaporator 135 is started. This arrangement allows the compressor 131 to continue to operate, preventing frequent turning on and off of the compressor 131. Further, when the first evaporator 134 needs to be started and operated and the second evaporator 135 is in a stop state, the compressor 131 of the refrigerator 10 is started, the first evaporator 134 is started and operated by the valve 133, and the second evaporator 135 can be started or stopped as required. When it is necessary to start up the first evaporator 134, and when the second evaporator 135 is in an operating state, the first evaporator 134 is started up by the valve 133.
Referring to fig. 4, in some embodiments of the present invention, other forms of refrigeration systems may be used, as long as the first evaporator 134 and the compressor 131 continue to operate. That is, when it is necessary to stop the operation of the first evaporator 134, the operation of the first evaporator 134 is stopped by the valve 133 and the second evaporator 135 to continue the operation of the compressor 131.
In some embodiments of the present invention, the heating device is an electric heating device, such as an electric heating wire, which is disposed on the first evaporator 134, so that the surface temperature of the first evaporator 134 can be increased. In an alternative embodiment of the present invention, the heating means is an electric heating rod disposed at the lower side of the first evaporator 134. The temperature of the surface of the first evaporator 134 is always at the condensation temperature by electrically heating the first evaporator 134, and compared with the arrangement that the temperature of the surface of the first evaporator 134 is always at the condensation temperature by adopting a four-way valve reversing mode, the refrigerator 10 of the invention can control the temperature of the first evaporator 134 more accurately and simply, and can defrost continuously. If the scheme of four-way valve reversing is adopted to heat the first evaporator 134, the control is complex, and the four-way valve needs to be frequently reversed, so that the service life is short, and the dehumidification continuity is poor.
Referring to fig. 1, in some embodiments of the present invention, the first storage compartment 11 is a refrigerator compartment and the second storage compartment 12 is a freezer compartment. The target refrigerating temperature of the refrigerating chamber 11 is 2-8 ℃, so that foods stored in the first storage compartment 11 can be kept fresh. The target refrigeration temperature of freezing chamber 12 is-16 degrees celsius to-22 degrees celsius, which allows for freezing of food items stored in second storage compartment 12.
In some embodiments of the invention, the condensation temperature is 0 to 0.5 degrees celsius. This arrangement reduces the power consumption of the electric heating wire for heating the first evaporator 134, and reduces the influence on the food stored in the first storage compartment 11 due to the excessive surface temperature of the first evaporator 134.
In an embodiment of the refrigerator 10, the refrigerator 10 further comprises a control device; the control device includes a processor and a memory, wherein the memory stores a control program and is used for realizing the control method of the refrigerator of any one of the above when the control program is executed by the processor.
