In the prior art, when the refrigerator is normally refrigerated, the heat generated by the heater and the lamp control system can be offset by the cold generated by the refrigeration of the refrigerator. However, when the refrigerator is abnormally cooled, the heat generated by the heater and the lamp control system cannot be offset, so that the temperature inside the refrigerator is rapidly increased, and the articles stored in the refrigerator may deteriorate or be damaged.
Therefore, a control method for a refrigerator is needed to timely handle the refrigerator when the refrigerator is abnormally cooled.

And then, when the temperature in the refrigerator at the second moment detected by the temperature detector is determined to be lower than the temperature in the refrigerator at the third moment detected by the temperature detector, controlling the compressor, the lamp control system and the heater to stop running. The second time and the third time are both later than the first time, the second time is earlier than the third time, and the time length between the second time and the third time is less than the preset time length.
The invention controls the operation of the refrigerator internal lamp control system, the heater and the compressor according to the internal temperature of the refrigerator. When the temperature in the refrigerator at the second moment is lower than the temperature in the refrigerator at the third moment, the fact that the internal temperature of the refrigerator is abnormal is shown, the control device timely turns off the lamp control system, the heater and the compressor in the refrigerator, and therefore the situation that the internal temperature of the refrigerator rapidly rises due to the fact that the lamp control system, the heater and the compressor do work to cause damage to articles in the refrigerator is avoided, and the problem that the refrigerator cannot be timely processed when refrigeration is abnormal is solved.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
Generally, a refrigeration system of a refrigerator is composed of four basic components, namely a compressor, a condenser, a throttle valve and an evaporator. The two are connected in sequence by a pipeline to form a closed system. The compressor draws in the lower pressure gaseous refrigerant from the evaporator, raising its pressure and sending it to the condenser. The liquid refrigerant is condensed into a liquid refrigerant with higher pressure in the condenser, the liquid refrigerant becomes the liquid refrigerant with lower pressure after being throttled by the throttle valve, the liquid refrigerant is sent into the evaporator, absorbs heat in the evaporator and evaporates to become a gaseous refrigerant with lower pressure, and then the gaseous refrigerant is sent into an inlet of the compressor, thereby completing the refrigeration cycle.
An embodiment of the present invention provides a refrigerator 01 as shown in fig. 1.
The refrigerator 01 includes a compressor 100, a lamp control system 200, and a heater 300 as shown in fig. 2 (a side view taken in the direction of 0-1 in fig. 1). In addition, the refrigerator 01 may further include a temperature detector 400 and a control device 500 as shown in fig. 3. The compressor 100, the lamp control system 200, the heater 300, and the temperature detector 400 are all connected to the control device 500.
The refrigerator provided by the embodiment of the invention is shown in figures 1, 2 and 3. Fig. 1 is a front view of the cooler, fig. 2 is a side view of the cooler, and fig. 3 shows the structure of the cooler. The refrigerator may include a compressor 100, a lamp control system 200, a heater 300, a temperature detector 400, and a control device 500 connected to the compressor 100, the lamp control system 200, the heater 300, and the temperature detector 400.
The refrigerator 01 may be a medicine refrigerator, a blood refrigerator, a medical low-temperature cabinet, a medicine refrigerator, a shady and cool box, a commercial display cabinet, or other devices or apparatuses having a low-temperature storage function, which is not limited in the embodiments of the present invention.
The compressor 100 is used to input cold air into the interior of the refrigerator in an operation state.
The light control system 200 is used to provide illumination to the interior of the cooler in the run state.
The heater 300 is used to remove condensation inside the refrigerator in an operating state.
The temperature detector 400 is used to detect the temperature inside the refrigerator.
The temperature detector 400 may be a thermocouple sensor, a thermistor sensor, a resistance temperature detector, an analog temperature sensor, a digital temperature sensor, or other types of temperature sensors, which is not limited in the embodiments of the present invention.
The control device 500 is configured to:
the lamp control system 200 and the heater 300 are controlled to start operation.
Alternatively, the control device 500 may directly turn on the lamp control system 200 and the heater 300, or may turn on the lamp control system 200 and the heater 300 by turning on other devices connected to the lamp control system 200 and the heater 300. For example: the control device 500 turns on the lamp control system 200 and the heater 300 by turning on the relays connected to the lamp control system 200 and the heater 300.
When it is determined that the first temperature detected by the temperature detector 400 is greater than the first threshold value, the compressor 100 is controlled to start operation.
Wherein the first temperature is a temperature inside the refrigerator at a first moment. The first threshold may be a set temperature of the refrigerator, for example: the temperature that needs to be maintained inside the freezer. Illustratively, the temperature to be maintained inside the refrigerator is preset to be 3 degrees.
For example, the control device 500 controls the compressor 100 to start operation when the temperature inside the refrigerator detected by the temperature detector 400 is 10 degrees at 12:00 on 1 st 2 nd 2020 and is greater than the first threshold value (3 degrees).
Alternatively, the control device 500 may directly control the compressor 100 to start operation, or may control other devices connected to the compressor 100 to start operation of the compressor 100. For example: the control device 500 enables the compressor 100 to start operation by controlling a relay connected to the compressor 100.
After controlling the compressor 100 to start running, the control device 500 is further configured to: when it is determined that the second temperature detected by the temperature detector 400 is less than the third temperature detected by the temperature detector 400, the compressor 100, the lamp control system 200, and the heater 300 are controlled to stop operating.
The second temperature is the temperature in the refrigerator at the second moment, the third temperature is the temperature in the refrigerator at the third moment, the second moment and the third moment are both later than the first moment, the second moment is earlier than the third moment, and the duration between the second moment and the third moment is less than the preset duration. The embodiment of the invention does not limit the value of the preset duration.
In practical applications, the temperature inside the refrigerator changes with the change of the operation state of the compressor 100. If the second temperature is less than or equal to the third temperature, the temperature in the refrigerator cabinet gradually rises along with the change of time. At this time, the compressor 100 is in an operating state, and thus, the compressor 100 may malfunction and the temperature inside the refrigerator cabinet may be abnormal. In this case, the control device 500 controls the compressor 100, the lamp control system 200, and the heater 300 to stop operating.
For example, the control device 500 obtains that the temperature of the inside of the refrigerator is 9 degrees at 12:30 at 2/1/2020, the control device 500 obtains that the temperature of the inside of the refrigerator is 10 degrees at 13:00 at 2/1/2020, and the temperature of the inside of the refrigerator at 12:30 at 2/1/2020 is lower than the temperature of the inside of the refrigerator at 13:00 at 2/1/2020, and the control device 500 controls the compressor 100, the lamp control system 200, and the heater 300 to stop operating.
Alternatively, the control device 500 may directly control the compressor 100, the lamp control system 200, and the heater 300 to stop operating, or may control other devices connected to the compressor 100, the lamp control system 200, and the heater 300 to stop operating. For example: the control device 500 stops the operation of the compressor 100, the lamp control system 200, and the heater 300 by controlling relays connected to the compressor 100, the lamp control system 200, and the heater 300.
Optionally, the control device 500 is further configured to:
and if the second temperature is determined to be higher than the third temperature, judging whether the third temperature is higher than a second threshold value.
It should be noted that the second temperature is higher than the third temperature, which indicates that the refrigerator can refrigerate normally. Further, in a normal refrigeration scene, it is also necessary to determine whether the refrigeration speed of the refrigerator is normal.
Generally, in the case where the cooling speed is normal, the temperature inside the refrigerator cabinet may be lower than the second threshold value. The second threshold value can be obtained according to the set temperature of the refrigerator, the control return difference temperature and the thermal effect temperature, wherein the thermal effect temperature refers to a change value of the internal temperature of the refrigerator after the refrigerator stops refrigerating for a period of time (for example, 1 hour). For example: if the temperature to be maintained in the refrigerator is set to 3 degrees, the controlled return difference temperature is set to 2 degrees, and the thermal effect temperature is set to 2 degrees, the second threshold may be 7 degrees (3+2+2 is 7 degrees).
If it is determined that the third temperature is greater than the second threshold value, the compressor 100, the lamp control system 200, and the heater 300 are controlled to stop operating.
It should be noted that the third temperature is equal to or higher than the second threshold, which indicates that the cooling speed of the refrigerator is abnormal, and the compressor 100, the lamp control system 200, and the heater 300 need to be controlled to stop operating.
Illustratively, the second threshold is 7 degrees, the temperature of the interior of the refrigerator is 8 degrees at 2/1/2020, and the temperature of the interior of the refrigerator at 13/00/2/1/2020 is greater than the second threshold, and the compressor 100, the lamp control system 200, and the heater 300 are controlled to stop operating.
If it is determined that the first temperature is less than the first threshold value, the compressor 100 is controlled to stop operating.
For example, the control device 500 controls the compressor 100 to stop operating when the temperature inside the refrigerator detected by the temperature detector 400 is 2 degrees at 12:00 on 1 st 2 nd 2020 and is lower than the first threshold value (3 degrees).
If it is determined that the first temperature is greater than the third threshold value, the compressor 100 starts to operate.
In order to increase the switching interval of the compressor 100 in the refrigerator and to improve the service life of the compressor 100, the first threshold value may be set as: the set temperature of the refrigerator + the return difference control temperature. The return difference temperature is the difference between the compressor 100 start-up temperature and the compressor 100 shut-down temperature. For example: if the temperature to be maintained in the refrigerator is set to 3 degrees and the return difference temperature is controlled to 2 degrees, the first threshold may be 5(2+3 is 5) degrees. The first threshold set according to the set temperature of the refrigerator + the control return difference temperature may also be referred to as a third threshold.
If it is determined that the first temperature is less than the first threshold, the compressor 100 is turned off after K seconds.
Wherein K is a positive integer.
It should be noted that, in order to avoid the compressor 100 in the refrigerator from being damaged due to frequent switching, when the detected first temperature is lower than the first threshold, the compressor 100 is turned off after K seconds (for example, 300 seconds) to continuously decrease the temperature in the refrigerator, so as to increase the time for the temperature in the refrigerator to rise back to the third threshold, reduce the switching frequency of the compressor 100, and avoid the compressor 100 from being damaged due to frequent switching. For example, when the first temperature is originally detected to be 2.9 degrees, the compressor 100 is turned off, and after 10 minutes, when the first temperature is detected to be 3.1 degrees, the compressor 100 is turned on. Now the first temperature is detected to be 2.9 degrees, the compressor 100 is switched off after 300 seconds and the compressor 100 is switched on when the first temperature is detected to be 3.1 degrees after 100 minutes. The switching interval of the compressor 100 is increased from 10 minutes to 100 minutes.
The control device 500 may be a control board, a single chip, a micro control unit, or other devices with control functions, which is not limited in the embodiments of the present invention. The control device 500 is used for controlling the refrigerator according to the control method of the refrigerator provided by the embodiment of the invention.
Optionally, as shown in fig. 3, the refrigerator in the embodiment of the present invention may further include an alarm device 600 connected to the control device 500. The alarm device 600 is used for sending out an alarm message when the refrigerator is abnormal, and the alarm message is used for indicating the refrigeration abnormality of the refrigerator.
It should be noted that, since the temperature inside the refrigerator is still increased after the compressor 100, the lamp control system 200 and the heater 300, it is necessary to notify a user or an operation and maintenance person to perform maintenance in time. Therefore, the control device 500 is also configured to: if it is determined that the second temperature is less than the third temperature or that the third temperature is greater than the second threshold, the alarm device 600 is activated.
The alarm device 600 may be a buzzer, an alarm lamp, a communication device, or other devices or apparatuses with an alarm function, which is not limited in the embodiments of the present invention. When the alarm device 600 is a communication device, the communication device may send an alarm message to other devices (e.g., a computer, a mobile phone, a tablet computer) after being activated, where the alarm message is used to indicate that the refrigerator is abnormally cooled.
Optionally, as shown in fig. 3, the refrigerator in the embodiment of the present invention may further include a display panel 700 connected to the control device 500.

The display panel 700 may be separate or integrated into the alarm device 600.

As shown in fig. 4, the circuit structure includes: the display panel 700, a control panel connected with the display panel 700, the compressor 100 connected with the relay of the control panel, the lamp control system 200, the heater 300, an external power grid 800 connected with the control panel, and the temperature detector 400 connected with the control panel.
The display panel 700 may be used to display the temperature detected by the temperature detector 400, and the control panel may be used to control the on and off of the relay according to the temperature detected by the temperature detector 400, and the compressor 100, the lamp control system 200, and the heater 300 connected thereto start to operate when the relay is turned on, whereas the compressor 100, the lamp control system 200, and the heater 300 connected thereto stop operating when the relay is turned off.
For example, when the control board determines that the temperature of the inside of the refrigerator detected by the temperature detector 400 is 8 degrees at 13:00 on 1 st/2/2020 and is greater than the second threshold (7 degrees), the control board controls the relay connected to the compressor 100, the relay connected to the lamp control system 200, and the relay connected to the heater 300 to be disconnected, and the compressor 100, the lamp control system 200, and the heater 300 are stopped.

The refrigerator is powered on for the first time, the internal temperature of the refrigerator is related to the environment where the refrigerator is located because the refrigerator does not start to refrigerate, and the internal temperature of the refrigerator is generally higher than the set temperature of the refrigerator, namely, is larger than the first threshold value. When the first temperature acquired by control device 500 is less than the first threshold value, control device 500 executes S310. When the first temperature acquired by control device 500 is greater than the first threshold value, control device 500 executes S304-S309.
Scene two: the freezer is not powered on for the first time.
When the refrigerator is not powered on for the first time, since the refrigerator starts to refrigerate, the temperature inside the refrigerator may be lower than the first threshold, and when the first temperature acquired by the control device 500 is smaller than the first threshold, the control device 500 performs S310. When the first temperature acquired by control device 500 is greater than the first threshold value, control device 500 executes S304-S309.
Optionally, in the second scenario, when the first temperature acquired by the control device 500 is greater than the first threshold, the control device 500 may further control the refrigerator according to the accumulated cooling time of the refrigerator and the second threshold, for example, when the first temperature acquired by the control device 500 is greater than both the first threshold and the second threshold and the accumulated cooling time of the refrigerator exceeds 60 minutes, the control device 500 turns off the lamp control system 200, the heater 300, and the compressor 100.
