With the development of smart technology, refrigerators may have one, two or more compartments, such as: refrigerating chamber, freezing chamber, temperature changing chamber, soft freezing chamber, etc., and the temperature range corresponding to each chamber is different. The temperature of the freezer compartment is typically below 0 deg., and in some areas, the temperature of the refrigerator compartment may be at an extreme near or below 0 deg. in winter conditions. In this way, some electric devices in the refrigerator may have the risk of icing, in the embodiment of the present disclosure, one, two or more areas where the electric devices configured with the motors are located of the refrigerator are configured with corresponding electric devices, so when the electric devices are in a working state, the on-off operation of the corresponding electric devices can be controlled according to the current rotation speed of the corresponding motors, thereby effectively reducing the probability of icing of the electric devices in the refrigerator, further reducing the probability of poor operation of the electric devices, ensuring the normal operation of the air conditioner under the low temperature condition, and improving the safety of the refrigerator. In addition, the switching time of the electric heating devices can be accurately controlled, and the heating power of each electric heating device can be more accurately controlled, so that the electric heating power consumption is reduced on the premise of ensuring the deicing efficiency of the refrigerator.

Fig. 1 is a schematic view of an application scenario of a refrigerator according to an embodiment of the present disclosure, where, as shown in fig. 1, the refrigerator is provided with three doors, and the three compartments respectively correspond to a refrigerating chamber, a freezing chamber, and a temperature changing chamber. In the embodiment of the disclosure, corresponding electric heating devices can be configured in the area where one, two or more electric devices with motors are located. Taking the refrigerator shown in fig. 1 as an example, if electric devices such as a fan and a damper are arranged in the refrigerating chamber, corresponding heating wires can be added on the fan and the damper. Of course, for the layout of the different electric devices, the corresponding electric heating devices may be arranged beside or behind some electric devices, which is not exemplified in detail.

Taking an example of an electric device provided with a corresponding electric heating device, the electric device is the current electric device, as in fig. 1, the fan in the refrigerating chamber may be the current electric device, and of course, if the fan in the temperature changing chamber is also provided with a corresponding electric heating device, the fan in the temperature changing chamber may also be the current electric device. When the current electric device is in a working state, the rotating speed of the motor of the current electric device can be monitored, and the switching operation of the current electric device corresponding to the current electric device can be controlled according to the rotating speed. In some embodiments, when the monitored current rotation speed of the motor of the current electric device is smaller and is in the first rotation speed range, the possibility of icing of the current electric device is indicated, and then the current electric device corresponding to the current electric device can be turned on and operated. If the monitored current rotation speed of the motor of the current electric device is larger and is in the second rotation speed range, the current electric device corresponding to the current electric device can be turned off in time, and resources are saved.

The first rotation speed range and the second rotation speed range can be determined according to the performance of the refrigerator, the electric device and the motor, the geographical position, the season and the like. Can be a fixed value or can be changed according to the working state. In some embodiments, monitoring a rotational speed of the current electrical device when it is in start-up operation, determining an average of the monitored rotational speeds over a set time period as a base rotational speed; and determining a first rotating speed range and a second rotating speed range according to the basic rotating speed.

For example: the current electric device starts running this time, namely, the rotating speed of the current electric device is monitored, the monitored rotating speed within 0.5, 1 or 2 minutes can be recorded by taking the starting running time of this time as a starting point, the average value of the rotating speeds is determined to be a basic rotating speed a, and then 45%, 50% or 60% of the basic rotating speed is determined to be the upper limit value of the first rotating speed range. For example: the first rotation speed range may be (0, a×50%) or (0, a×60%) and so on. Likewise, 85%, 90% or 95% of the base rotational speed may be determined as the lower limit value of the second rotational speed range. In view of saturation performance of the motor, 105%, 110% or 115% of the basic rotation speed may be determined as the upper limit value of the second rotation speed range, and thus the second rotation speed range may be (a×85%, a×115%) or (a×90%, a×110%) or the like.

It can be seen that after the electric heating devices are disposed in the refrigerator, the electric heating devices can be controlled to be turned on or off according to the current rotation speed of the electric heating devices.

Fig. 2 is a flowchart illustrating an anti-icing control method for a refrigerator according to an embodiment of the present disclosure. The refrigerator is provided with corresponding electric heating devices in the area where one or more electric devices carrying a motor are located, as shown in fig. 2, and the process of ice protection control of the refrigerator comprises the following steps:

step 201: and under the condition that the current electric device is in the working state, acquiring the current rotating speed of the motor of the current electric device.

The current electric appliance is started to be in a working state, and the refrigerator can monitor the rotating speed of the motor of the current electric device from the starting time, wherein the current time corresponds to the current rotating speed.

Step 202: and controlling the switching operation of the current electric heating device corresponding to the current electric device according to the current rotating speed.

In some embodiments, controlling the current electric heating device to operate on, if the current rotational speed is determined to be in the first rotational speed range; and controlling the current electric heating device to be turned off under the condition that the current rotating speed is determined to be in a second rotating speed range, wherein the lower limit value of the second rotating speed range is larger than the upper limit value of the first rotating speed range.

The first rotation speed range and the second rotation speed range can be determined according to the performance of the refrigerator, the electric device and the motor, the geographical position, the season and the like. For example: the first and second rotational speed ranges may be determined according to historical usage data of the refrigerator. Or after the limit test is carried out when the refrigerator leaves the factory, the first rotating speed range and the second rotating speed range are determined.

In some embodiments, the rotational speed of the current electric device during the start-up operation can be monitored, and the average value of the rotational speeds in the monitored set time is determined as the basic rotational speed; and determining a first rotating speed range and a second rotating speed range according to the basic rotating speed.

The setting time may be 30s, 60s, or 90s, etc., so that from the current start-up running time of the current electric device, the rotation speed monitored in 30s, 60s, or 90s is averaged to obtain the basic rotation speed a, and then 40%, 50% or 60% of the basic rotation speed is determined as the upper limit value of the first rotation speed range. For example: the first rotation speed range may be (0, a×50%) or (0, a×60%) and so on. Likewise, 85%, 90% or 95% of the base rotational speed may be determined as the lower limit value of the second rotational speed range. In view of saturation performance of the motor, 103%, 110% or 115% of the basic rotation speed may be determined as the upper limit value of the second rotation speed range, and thus the second rotation speed range may be (a×87%, a×113%) or (a×90%, a×110%) or the like.

Thus, in some embodiments, determining the first and second rotational speed ranges includes: determining 50% of the basic rotation speed as an upper limit value of the first rotation speed range; determining 90% of the base rotational speed as a lower limit value of the second rotational speed range; 110% of the base rotational speed is determined as the upper limit value of the second rotational speed range.

Thus, if the current rotating speed b is less than the basic rotating speed a by 50%, the possibility of icing exists in the current electric device, and the current electric device corresponding to the current electric device can be turned on and operated. If a is 90 percent < b is 110 percent, the current electric heating device corresponding to the current electric device can be turned off in time, and resources are saved.

Therefore, when the electric devices are in a working state, the corresponding electric devices can be controlled to operate according to the current rotating speed of the corresponding motors, so that the probability of freezing of the electric devices in the refrigerator is effectively reduced, the probability of poor operation of the electric devices is further reduced, the normal operation of the air conditioner under the condition of low temperature is ensured, the safety of the refrigerator is improved, the switching time of the electric devices can be accurately controlled, and the heating power of each electric device can be accurately controlled, so that the electric heating power consumption is reduced on the premise of ensuring the deicing efficiency of the refrigerator.

When the current electric device is in a working state, the corresponding switch operation of the current electric device can be controlled according to the current rotating speed of the motor of the current electric device. In some embodiments, under the condition that the current electric device is in a non-working state, acquiring the current temperature of a chamber in which the current electric device is located; and controlling the switching operation of the current electric heating device corresponding to the current electric device according to the current temperature. I.e. controlling the switching operation of the electric heating device in dependence of the temperature.

The refrigerator may have one, two or more compartments, for example: refrigerating chamber, freezing chamber, temperature changing chamber, soft freezing chamber, etc., and the temperature range corresponding to each chamber is different. For example: the freezing chamber is at-3-21 ℃, the refrigerating chamber is at 2-6 ℃, and the temperature changing chamber is at-7-0 ℃, so that the current temperature of the chamber where the current electric device is can be obtained because the chamber where the current electric device is different.

In some embodiments, controlling the switching operation of the current electrical device corresponding to the current electrical device includes: determining a current turn-on rate of the current electric heating device according to the current temperature; and controlling the switching operation of the current electric heating device according to the current turn-on rate.

The correspondence between the temperature range and the opening rate of the electric heating device may be maintained in the refrigerator in advance, and of course, the lower the temperature, the higher the opening rate. Thus, the current temperature of the compartment where the current electric device is located is obtained, and the current opening rate corresponding to the current temperature can be determined according to the corresponding relation; then, the switching operation of the current electric heating device is controlled according to the current turn-on rate.

Therefore, the switching time of the electric heating devices can be accurately controlled according to the room temperature, and the heating power of each electric heating device can be further accurately controlled, so that the electric heating power consumption is reduced on the premise of ensuring the deicing efficiency of the refrigerator.

The following integrates the operation flow into a specific embodiment, and illustrates the anti-icing control process for the refrigerator provided by the embodiment of the invention.

Step 302: the refrigerator monitors the rotational speed of a motor of a blower in a refrigerating compartment.

Step 303: is it determined that the refrigerator compartment blower has been running for 1 minute? If yes, go to step 304, otherwise, return to step 302.

Step 304: the refrigerator averages the detected rotation speed within 1 minute to obtain a basic rotation speed a, determines (0, a×50%) as a first rotation speed range, and determines (a×90%, a×110%) as a second rotation speed range.

Step 305: the refrigerator obtains the current rotation speed b of the motor of the blower in the refrigerating chamber.

Step 306: whether or not the refrigerator determines that b is within (0, 50%) a? If yes, go to step 307, otherwise, go to step 308.

Step 307: the refrigerator turns on the heating wire on the fan in the refrigerating chamber, and performs step 310.

Step 308: is the refrigerator determining b is within (a x 90%, a x 110%? If yes, go to step 309, otherwise, go to step 310.

Step 309: the refrigerator turns off the heating wire on the fan in the refrigerating compartment, and performs step 310.

Step 310: is the air blower in the refrigerator compartment in operation? If yes, go back to step 305, otherwise, go to step 311.

Step 311: the refrigerator obtains the current temperature of the refrigerating chamber, and determines the current opening rate corresponding to the current temperature according to the stored corresponding relation.

Step 312: the refrigerator controls the switch operation of the heating wire on the fan according to the current turn-on rate, and the process goes to step 301.

It can be seen that in this embodiment, the refrigerator can control the switch operation of the heater strip above the fan of different states according to the rotational speed of the fan and the temperature of the refrigerating chamber respectively, thereby effectively reducing the probability of freezing of electric devices in the refrigerator, further reducing the probability of poor operation of the electric devices, guaranteeing the normal operation of the air conditioner under the low temperature condition, improving the safety of the refrigerator, and accurately controlling the switch time of the electric heater devices, further accurately controlling the heating power of each electric heater device, thereby reducing the electrothermal power consumption on the premise of guaranteeing the deicing efficiency of the refrigerator.

The anti-icing control procedure for the anti-icing control means of the refrigerator is further described below in connection with the embodiments.

In an embodiment of the disclosure, as shown in fig. 1, a refrigerator may have electrical devices such as a fan and a damper in the temperature changing chamber, and corresponding heating wires may be added above the fan and the damper. The fan in the temperature changing chamber is used as the current electric device. And, the correspondence between the temperature range and the opening rate of the heating wire is preserved in the refrigerator.

If b is 60%, the first control unit 421 in the first control module 420 may turn on the heating wire on the fan in the temperature changing chamber; and if a is 80% < b is 120%, the second control unit 422 in the first control module 420 can turn off the heating wire above the fan in the temperature changing chamber.
