Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, for example, to a method and device for controlling a refrigerator, and a refrigerator. Background Art

[0002] In order to meet people's diverse home needs, free-built-in refrigerators are gradually becoming popular. Free-built-in refrigerators can be installed both freely and built-in. When the refrigerator is placed in a closed wooden cabinet or an open wooden cabinet when in use, the refrigerator is in a built-in installation state. When the refrigerator is in use without any obstruction or restriction such as a wooden cabinet, the refrigerator is in a free-style installation state.

[0003] At present, when controlling a refrigerator in the related art, no matter the refrigerator is in an embedded installation state or a free installation state, it is controlled in the same operation mode. Compared with the free installation state, the ventilation and heat dissipation of the refrigerator in the embedded installation state is suppressed by the wooden cabinet, so the refrigerator in the embedded installation state needs to increase the heat dissipation. The refrigerator in the free installation state has better ventilation and heat dissipation, and needs to reduce the heat dissipation. Therefore, controlling the refrigerator in a fixed operation mode cannot accurately control the refrigerator.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0034] In the disclosed embodiments, the electronic device can be connected to the refrigerator as described above by connecting to the Internet, or can be directly connected to the refrigerator as described above by Bluetooth, WiFi, etc. In some embodiments, the electronic device is, for example, a mobile device, a computer, or a server, or any combination thereof. The mobile device may include, for example, a mobile phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, or any combination thereof, wherein the wearable device may include, for example, a smart watch, a smart bracelet, a pedometer, etc.

[0035] Embedded installation refers to the installation method where the refrigerator is embedded in a cabinet or wall. At this time, the side wall of the refrigerator is close to the cabinet or wall, and the gap between the two is very small. Free installation refers to the installation method where the refrigerator is open. At this time, the side wall of the refrigerator is far away from the cabinet or wall, and the gap between the two is large.

[0036] A first environment information acquisition device is provided at a first preset position of the refrigerator, and a second environment information acquisition device is provided at a second preset position. Both the first environment information acquisition device and the second environment information acquisition device are used to acquire environment information of the environment in which the refrigerator is located. In one embodiment, Figure 1 Schematic diagram of the structure of refrigerator 100. Figure 1 As shown, the first preset position is in the hinge box at the top of the refrigerator 100. The first environment information acquisition device 101 is set in the hinge box at the upper left corner of the refrigerator 100. The second preset position is the display screen on the refrigerator door. The second environment information acquisition device 102 is set on the refrigerator door display screen 103. In this way, the first environment information acquisition device and the second environment information acquisition device are set on the top and door of the refrigerator, so that the environment information acquisition device will not be affected by the wooden cabinet, and can effectively perceive the environment information, so that the current installation status of the refrigerator can be determined more accurately.

[0037] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling a refrigerator, comprising:

[0038] Step S201: The electronic device uses a first environment information acquisition device to acquire first environment information a first preset number of times, and uses a second environment information acquisition device to acquire second environment information a first preset number of times.

[0039] Step S202: The electronic device determines the installation status of the refrigerator according to the first environmental information and the second environmental information.

[0040] Step S203: the electronic device controls the operation of the refrigerator according to the installation status.

[0041] The method for controlling a refrigerator provided by the embodiment of the present disclosure is adopted, by respectively setting an environmental information acquisition device at a first preset position and a second preset position of the refrigerator, and determining the installation state of the refrigerator through environmental information acquired by the environmental information acquisition device of the refrigerator, and then controlling the operation of the refrigerator according to the current installation state of the refrigerator. Since the current installation state of the refrigerator is taken into account when controlling the operation of the refrigerator, the refrigerator can be controlled more accurately. Thus, the accuracy of controlling the refrigerator is improved.

[0042] Optionally, before the electronic device acquires the first environment information and the second environment information, it further includes: determining whether the first environment information acquisition device and the second environment information acquisition device of the refrigerator are faulty. If neither the first environment information acquisition device nor the second environment information acquisition device is faulty, the first environment information acquisition device is used to acquire the first environment information for a first preset number of times, and the second environment information acquisition device is used to acquire the second environment information for a first preset number of times. The first preset number is greater than or equal to any value in 1440.

[0043] Optionally, before the electronic device acquires the first environment information and the second environment information, it further includes: determining whether the cumulative operating time of the refrigerator is greater than or equal to a first preset time, and if the cumulative operating time is greater than or equal to the first preset time, acquiring the first environment information a first preset number of times using the first environment information acquisition device, and acquiring the second environment information a first preset number of times using the second environment information acquisition device. For example, the first preset time is 24 hours.

[0044] Optionally, before the electronic device acquires the first environment information and the second environment information, it further includes: determining whether the current operating state of the refrigerator is a set operating state. When the operating state is the set operating state, the first environment information is acquired a first preset number of times using the first environment information acquisition device, and the second environment information is acquired a first preset number of times using the second environment information acquisition device. For example, the operating state is set to a refrigeration state, etc.

[0045] In some embodiments, the electronic device uses the first environment information acquisition device to acquire the first environment information once every set time, and acquires the first environment information a total of a first preset number of times. The electronic device uses the second environment information acquisition device to acquire the second environment information once every set time, and acquires the second environment information a total of a first preset number of times. The set time is 30 seconds.

[0046] Optionally, the first environmental information includes a first environmental temperature. The second environmental information includes a second environmental temperature. The first environmental information acquisition device is a first temperature sensor, and the second environmental information acquisition device is a second temperature sensor. The first temperature sensor is set at the top of the refrigerator, and the second temperature sensor is set on the door of the refrigerator, so that the temperature sensor will not be affected by the wooden cabinet, can effectively sense the ambient temperature, and use multiple ambient temperatures collected by multiple temperature sensors to more accurately determine the current installation status of the refrigerator.

[0047] Determining the installation state of the refrigerator according to the first environmental information and the second environmental information includes: subtracting the first environmental temperature obtained each time from the second environmental temperature to obtain a plurality of first difference values. Determining the first difference value greater than or equal to the preset value as the environmental temperature target difference value. Determining the installation state of the refrigerator according to the number of environmental temperature target difference values. In this way, by using multiple temperature sensors to sense the difference in environmental temperature, the current installation state of the refrigerator can be determined more accurately.

[0048] Optionally, determining the installation status of the refrigerator according to the number of ambient temperature target differences includes: when a ratio of the number of ambient temperature target differences to a first preset number satisfies a first preset condition, determining that the installation status of the refrigerator is an embedded installation status.

[0049] The first preset condition is that the ratio of the number of ambient temperature target differences to the first preset number is greater than or equal to a fourth set value. For example, the fourth set value is 60%.

[0050] Optionally, the refrigerator includes a cooling fan, which is arranged at the bottom of the refrigerator. Controlling the operation of the refrigerator according to the installation state includes: when the installation state of the refrigerator is an embedded installation state, controlling the cooling fan of the refrigerator to operate at a first preset fan speed, and controlling the compressor of the refrigerator to operate at a first preset compressor speed.

[0051] The first preset fan speed = the current cooling fan speed + 10% of the current cooling fan speed. When the refrigerator is in an embedded installation state, the heat dissipation of the side plate condenser and the back condenser of the refrigerator is suppressed, which will make the refrigerator's cooling effect poor. By increasing the speed of the cooling fan to increase the heat dissipation effect, the refrigerator's cooling performance can be guaranteed.

[0052] The first preset compressor speed=the current compressor speed-5% of the current compressor speed. When the refrigerator is in an embedded installation state, the heat load of the refrigerator is reduced by reducing the speed of the refrigerator compressor.

[0053] By arranging multiple temperature sensors at different positions of the refrigerator and determining the installation status of the refrigerator through the temperature collected by each temperature sensor, it is possible to automatically judge the usage environment of the refrigerator, thereby accurately controlling the operation of the refrigerator and improving the efficiency and performance of the refrigerator.

[0054] In some embodiments, the refrigerator further comprises a side plate condenser, a back condenser and a solenoid valve. The side plate condenser is arranged on the side plate of the refrigerator. The back condenser is arranged on the back plate of the refrigerator. One end of the refrigerator compressor is connected to one end of the microchannel condenser, and the other end of the microchannel condenser is connected to the first end of the solenoid valve. The second end of the solenoid valve is connected to one end of the side plate condenser, the third end is connected to one end of the back condenser, and the fourth end is connected to the de-condensation pipe. The other end of the side plate condenser and the other end of the back condenser are both connected to the de-condensation pipe. The de-condensation pipe is sequentially connected to the capillary tube, the evaporator, the return air pipe and the compressor.

[0055] Optionally, controlling the operation of the refrigerator according to the installation state further includes: when the installation state of the refrigerator is an embedded installation state, controlling the solenoid valve to allow the refrigerant to flow directly to the dew removal pipe, so that the refrigerant does not flow to the side plate condenser and the back condenser. The fan heat of the side plate and the back plate is reduced. The refrigerator is converted from natural convection heat dissipation to bottom fan forced heat dissipation. Thereby, the heat dissipation effect is increased and the refrigeration performance of the refrigerator in the embedded installation state is improved.

[0056] Optionally, after controlling the operation of the refrigerator according to the installation state, the method further includes: determining whether the first environment information acquisition device and the second environment information acquisition device of the refrigerator fail. If both the first environment information acquisition device and the second environment information acquisition device fail, the refrigerator is determined to be in a free installation state.

[0057] Optionally, after controlling the operation of the refrigerator according to the installation status, it also includes: when the cumulative operating time of the refrigerator is greater than or equal to a second preset time, and when the ratio of the number of ambient temperature target differences to the first preset number meets the second preset condition, determining that the installation status of the refrigerator is a free-style installation status.

[0058] The second preset condition is that the ratio of the number of ambient temperature target differences to the first preset number is less than a fifth set value. For example, the fifth set value is 30%.

[0059] Optionally, after determining that the installation state of the refrigerator is the free-style installation state, the method further includes controlling a cooling fan of the refrigerator to operate at a second preset fan speed, and controlling a compressor of the refrigerator to operate at a second preset compressor speed. The second preset fan speed is less than the first preset fan speed. The second preset compressor speed is greater than the first preset compressor speed.

[0060] When the refrigerator is installed in a free-style state, the heat dissipation is good, and the cooling fan runs at a lower speed. This can save electricity. When the refrigerator is installed in an embedded state, the heat dissipation of the side plate condenser and the back condenser is suppressed, the refrigeration effect is poor, and the cooling fan runs at a higher speed. This increases the heat dissipation effect, thereby ensuring the refrigeration performance of the refrigerator. In this way, when controlling the operation of the refrigerator, the installation state of the refrigerator is taken into consideration, and the use environment of the refrigerator is distinguished. In different use environments, the refrigerator adopts differentiated control solutions. This can control the operation of the refrigerator more accurately and effectively.

[0061] Combination Figure 3 As shown, another method for controlling a refrigerator provided by an embodiment of the present disclosure includes:

[0062] Step S301: The electronic device detects whether a first temperature sensor and a second temperature sensor fail.

[0063] Step S302: When both the first temperature sensor and the second temperature sensor are not faulty, the electronic device obtains the accumulated operating time of the refrigerator.

[0064] Step S303: When the accumulated operation time of the refrigerator is greater than or equal to the first preset time, the electronic device determines the current operation state of the refrigerator.

[0065] Step S304, when the refrigerator is in a set operating state, the electronic device uses the first temperature sensor to obtain the first ambient temperature once every set time period, and uses the second temperature sensor to obtain the second ambient temperature once every set time period, and obtains a first preset number of first ambient temperatures and a first preset number of second ambient temperatures.

[0066] Step S305 , the electronic device subtracts the first ambient temperature obtained each time from the second ambient temperature to obtain a plurality of first difference values; and determines the first difference value that is greater than or equal to a preset value as the ambient temperature target difference value.

[0067] Step S306: When the ratio of the number of ambient temperature target differences to the first preset number is greater than or equal to a fourth set value, the electronic device determines that the installation state of the refrigerator is an embedded installation state.

[0068] Step S307, when the installation state of the refrigerator is the embedded installation state, the electronic device controls the cooling fan of the refrigerator to run at a first preset fan speed, and controls the compressor of the refrigerator to run at a first preset compressor speed.

[0069] In step S308, the electronic device determines whether the accumulated operating time of the refrigerator is greater than or equal to the second preset time, and whether the ratio of the number of target ambient temperature differences to the first preset number is less than the fifth set value; if so, execute step S309; ​​if not, return to execute step S307.

[0070] Step S309, the electronic device determines that the installation state of the refrigerator is a free-style control state, and controls the cooling fan of the refrigerator to operate at a second preset fan speed, and controls the compressor of the refrigerator to operate at a second preset compressor speed. The second preset fan speed is less than the first preset fan speed. The second preset compressor speed is greater than the first preset compressor speed.

[0071] When the refrigerator is installed in a free-style state, the heat dissipation is good, and the cooling fan runs at a lower speed. This can save electricity. When the refrigerator is installed in an embedded state, the heat dissipation of the side plate condenser and the back condenser is suppressed, the refrigeration effect is poor, and the cooling fan runs at a higher speed. This increases the heat dissipation effect, thereby ensuring the refrigeration performance of the refrigerator. In this way, when controlling the operation of the refrigerator, the installation state of the refrigerator is taken into consideration, and the use environment of the refrigerator is distinguished. In different use environments, the refrigerator adopts differentiated control solutions. This can control the operation of the refrigerator more accurately and effectively.

[0072] Optionally, the refrigerator is provided with a temperature detection device, and the temperature detection device is used to detect the temperature of the side plate of the refrigerator. The method further includes: using the temperature detection device to detect the temperature of the side plate a first preset number of times.

[0073] In some embodiments, in combination Figure 4 As shown, a first environment information acquisition device 101 is arranged in the hinge box at the upper left corner of the refrigerator 100. A second environment information acquisition device 102 is arranged on the door display screen 103 of the refrigerator 100. A temperature detection device 104 is arranged on the side panel of the refrigerator and close to the side panel condenser.

[0074] Determine the installation status of the refrigerator according to the number of target ambient temperature differences, including: when the ratio of the number of target ambient temperature differences to the first preset number meets the first preset condition, obtain the ambient temperature categories corresponding to each second ambient temperature, and obtain the ambient temperature reference value corresponding to each ambient temperature category; subtract the temperature of each side panel from the corresponding ambient temperature reference value to obtain a number of second differences. Determine the installation status of the refrigerator according to each second difference and the number of ambient temperature categories. When the refrigerator is in the embedded installation state, the side panels of the refrigerator have poor heat dissipation, and the temperature around the side panels of the refrigerator is higher than that in the free installation state. In this way, the difference in the temperature of the refrigerator side panels can be used to more accurately determine the current installation status of the refrigerator.

[0075] Further, obtaining the ambient temperature categories corresponding to the second ambient temperatures and obtaining the ambient temperature reference values ​​corresponding to the ambient temperature categories includes: performing a search operation in a preset data table according to the second ambient temperature to find the ambient temperature categories and ambient temperature reference values ​​corresponding to the second ambient temperature. The preset data table stores the correspondence between the ambient temperatures, ambient temperature categories, and ambient temperature reference values.

[0076] In some embodiments, the ambient temperature categories include: less than or equal to 10°C category, greater than 10°C and less than or equal to 20°C category, greater than 20°C and less than or equal to 30°C category, greater than 30°C and less than or equal to 40°C category. Among them, the ambient temperature reference value corresponding to the category less than or equal to 10°C is 15°C, the ambient temperature reference value corresponding to the category greater than 10°C and less than or equal to 20°C is 23°C, the ambient temperature reference value corresponding to the category greater than 20°C and less than or equal to 30°C is 38°C, and the ambient temperature reference value corresponding to the category greater than 30°C and less than or equal to 40°C is 44°C. For example, the second ambient temperature obtained is 9.5°C, and the corresponding ambient temperature category is less than or equal to 10°C category found from the preset data table, and the corresponding ambient temperature reference value is 15°C. For another example, the second ambient temperature obtained is 14°C, and the corresponding ambient temperature category is greater than 10°C and less than or equal to 20°C category found from the preset data table, and the corresponding ambient temperature reference value is 23°C.

[0077] Optionally, determining the installation state of the refrigerator according to each second difference and the number of ambient temperature categories includes: calculating the average of each second difference to obtain an average difference. When the average difference is greater than or equal to the first set value and the number of ambient temperature categories is less than or equal to the second set value, determining that the installation state of the refrigerator is an embedded installation state. The first set value is 2. The second set value is 6.

[0078] In some embodiments, the second ambient temperature obtained for the first time is 9.5°C, and the side panel temperature is 12°C. From the preset data table, it is found that the ambient temperature category corresponding to 9.5°C is less than or equal to the 10°C category, and the corresponding ambient temperature reference value is 15°C. Then the first second difference is 15°C-12°C=3°C. After an interval of 30s, the second ambient temperature is 11°C and the side panel temperature is 14°C. From the preset data table, it is found that the ambient temperature category corresponding to 11°C is greater than 10°C and less than or equal to 20°C, and the corresponding ambient temperature reference value is 23°C. Then the second second difference is 23°C-14°C=9°C. Among them, the first preset number is 1440. 1440 data collections are performed on the environmental information and the side panel temperature of the refrigerator. 1440 second ambient temperature data and 1440 side panel temperature data are obtained. Then 1440 second differences are obtained. The average value of the 1440 second differences is calculated. When the average difference is greater than or equal to 2 and the number of ambient temperature categories is less than or equal to 6, it is determined that the installation state of the refrigerator is an embedded installation state.

[0079] Combination Figure 5 As shown, another method for controlling a refrigerator provided by an embodiment of the present disclosure includes:

[0080] Step S501: The electronic device detects whether a first temperature sensor and a second temperature sensor fail.

[0081] Step S502: When neither the first temperature sensor nor the second temperature sensor fails, the electronic device obtains the accumulated operating time of the refrigerator.

[0082] Step S503: When the accumulated operation time of the refrigerator is greater than or equal to the first preset time, the electronic device determines the current operation state of the refrigerator.

[0083] Step S504, when the refrigerator is in a set operating state, the electronic device uses the first temperature sensor to obtain the first ambient temperature once at a set time interval, uses the second temperature sensor to obtain the second ambient temperature once at a set time interval, and uses the temperature detection device to obtain the side panel temperature of the refrigerator once at a set time interval, and obtains the first ambient temperature a first preset number of times, the second ambient temperature a first preset number of times, and the side panel temperature a first preset number of times.

[0084] Step S505, the electronic device subtracts the first ambient temperature obtained each time from the second ambient temperature to obtain a plurality of first difference values; and determines the first difference value that is greater than or equal to a preset value as the ambient temperature target difference value.

[0085] Step S506, when the ratio of the number of ambient temperature target differences to the first preset number is greater than or equal to a fourth set value, obtaining ambient temperature categories corresponding to each second ambient temperature, and obtaining ambient temperature reference values ​​corresponding to each ambient temperature category.

[0086] Step S507, subtracting the temperature of each side plate from the corresponding ambient temperature reference value to obtain a plurality of second difference values;

[0087] Step S508, calculate the average value of each second difference to obtain the average difference; when the average difference is greater than or equal to the first set value and the number of ambient temperature categories is less than or equal to the second set value, determine that the installation state of the refrigerator is an embedded installation state.

[0088] Step S509, when the installation state of the refrigerator is the embedded installation state, the electronic device controls the cooling fan of the refrigerator to run at a first preset fan speed, and controls the compressor of the refrigerator to run at a first preset compressor speed.

[0089] In step S510, the electronic device determines whether the accumulated operating time of the refrigerator is greater than or equal to the second preset time, and whether the ratio of the number of target ambient temperature differences to the first preset number is less than the fifth set value; if so, execute step S511; if not, return to execute step S509.

[0090] Step S511, the electronic device determines that the installation state of the refrigerator is a free-style control state, and controls the cooling fan of the refrigerator to operate at a second preset fan speed, and controls the compressor of the refrigerator to operate at a second preset compressor speed. The second preset fan speed is less than the first preset fan speed. The second preset compressor speed is greater than the first preset compressor speed.

[0091] When the refrigerator is in a free-style installation state, the heat dissipation is good and the cooling fan runs at a lower speed. It can save electricity. When the refrigerator is in an embedded installation state, the heat dissipation of the side panel condenser and the back condenser is suppressed, the refrigeration effect is poor, and the cooling fan runs at a higher speed. Increase the heat dissipation effect, thereby ensuring the refrigeration performance of the refrigerator. In this way, when controlling the operation of the refrigerator, the installation state of the refrigerator is taken into consideration, and the use environment of the refrigerator is distinguished. Under different use environments, the refrigerator adopts differentiated control schemes. It can control the operation of the refrigerator more accurately and effectively. In addition, when determining the installation state of the refrigerator, the temperature of the side panel of the refrigerator is taken into consideration, so that the current installation state of the refrigerator can be determined more accurately, and the control can be more accurately controlled.

The first humidity sensor is arranged at the top of the refrigerator, and the second humidity sensor is arranged on the door of the refrigerator, so that the humidity sensor will not be affected by the wooden cabinet, and can effectively sense the environmental humidity, and the environmental humidity of multiple places collected by multiple humidity sensors can more accurately determine the current installation status of the refrigerator.

[0093] Determining the installation state of the refrigerator according to the first environmental information and the second environmental information includes: calculating the average value of the first environmental humidity for a first preset number of times to obtain the first humidity average value; and calculating the average value of the second environmental humidity for a first preset number of times to obtain the second humidity average value. Determining the installation state of the refrigerator according to the first humidity average value and the second humidity average value. In this way, using multiple humidity sensors to sense the difference in environmental humidity, the current installation state of the refrigerator can be determined more accurately.

[0094] Optionally, determining the installation state of the refrigerator according to the first average humidity value and the second average humidity value includes: determining that the installation state of the refrigerator is an embedded installation state when the difference between the first average humidity value and the second average humidity value is greater than or equal to a third set value, wherein the third set value is 6%.

[0095] Optionally, after controlling the operation of the refrigerator according to the installation state, the method further includes: determining that the installation state of the refrigerator is a free-style installation state when the cumulative operation time of the refrigerator is greater than or equal to a second preset time and the difference between the first humidity average value and the second humidity average value is less than or equal to a sixth setting value. The sixth setting value is 3%.

[0096] Combination Figure 6 As shown, the method for controlling a refrigerator provided by the embodiment of the present disclosure includes:

[0097] Step S601: The electronic device detects whether the first humidity sensor and the second humidity sensor fail.

[0098] Step S602: When neither the first humidity sensor nor the second humidity sensor fails, the electronic device obtains the accumulated operating time of the refrigerator.

[0099] Step S603: When the accumulated operation time of the refrigerator is greater than or equal to the first preset time, the electronic device determines the current operation state of the refrigerator.

[0100] Step S604, when the refrigerator is in a set operating state, the electronic device uses the first humidity sensor to obtain the first ambient humidity once every set time period, and uses the second humidity sensor to obtain the second ambient humidity once every set time period, and obtains a first preset number of first ambient humidity and a first preset number of second ambient humidity.

[0101] Step S605, the electronic device calculates an average value of the first ambient humidity for a first preset number of times to obtain a first humidity average value; and calculates an average value of the second ambient humidity for a first preset number of times to obtain a second humidity average value.

[0102] Step S606: When the difference between the first humidity average value and the second humidity average value is greater than or equal to the third set value, the electronic device determines that the installation state of the refrigerator is the embedded installation state.

[0103] Step S607, when the installation state of the refrigerator is the embedded installation state, the electronic device controls the cooling fan of the refrigerator to run at a first preset fan speed, and controls the compressor of the refrigerator to run at a first preset compressor speed.

[0104] In step S608, the electronic device determines whether the accumulated operating time of the refrigerator is greater than or equal to the second preset time, and whether the difference between the first humidity average value and the second humidity average value is less than the sixth set value; if so, execute step S609; if not, return to execute step S607.
