Based on the above structure, various embodiments of a refrigerator control method are provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a refrigerator control method according to the present invention.
Embodiments of the present invention provide an embodiment of a refrigerator control method, and it should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that here. The executing subject of each embodiment of the refrigerator control method of the present invention may be a smart phone, a personal computer, a server, and other devices, and for convenience of description, the refrigerator is taken as the executing subject in the following embodiments for explanation. In this embodiment, a refrigerator control method includes:
and step S10, if the ambient temperature is detected to be within the target temperature range and the refrigerator meets the preset low-energy consumption switching condition, controlling the refrigerator to enter a low-energy consumption mode corresponding to the target temperature range.
With the release of new standards of European household refrigerators, products under the old standards of the European household refrigerators need to meet the energy efficiency improvement of about 20% in order to reach the product grades under the new standards of Europe, most of domestic refrigerator manufacturers either redevelop or adjust the layout of old products, replace more efficient compressors or thicken heat insulation layers, use VIP vacuum insulation panels and other schemes, and the schemes have too high cost or too long development period, are not beneficial to market competition, and have low cost performance.
In order to solve the above problem, in this embodiment, a low energy consumption mode of the refrigerator is provided, and when the refrigerator enters a test temperature range of a new standard, the refrigerator is controlled to enter the low energy consumption mode, so as to reduce power consumption of the refrigerator at the test temperature, thereby meeting the requirement of the new standard on energy efficiency.
Specifically, during operation of the refrigerator after power-on, ambient temperature is collected by an ambient temperature sensor provided in the refrigerator. The ambient temperature sensor may collect ambient temperature in real time or at intervals to save refrigerator performance. And after the ambient temperature is collected, detecting whether the ambient temperature is in a target temperature range. The target temperature range may be a preset temperature range, and it should be noted that there may be a plurality of target temperature ranges if different low energy consumption modes are set for different temperature ranges. For example, the new standard where the test temperatures are 16 ℃ and 32 ℃, then the target temperature ranges may be at least two: a temperature range comprising 16 ℃ and a temperature range comprising 32 ℃; other temperature ranges may also be included, without limitation. Wherein a temperature range including 16 ℃ means that a temperature range including 16 ℃ is a temperature range, for example, a temperature range of 13 ℃ to 17 ℃. According to the preset, the values of the two endpoints may be included, or the values of the two endpoints may not be included. Wherein a temperature range including 32 ℃ means that a temperature range including 32 ℃ is a temperature range, for example, a temperature range of 29 ℃ to 33 ℃. According to the preset, the values of the two endpoints may be included, or the values of the two endpoints may not be included.
And if the ambient temperature is detected to be within the target temperature range, detecting whether the refrigerator meets a preset low energy consumption switching condition. The preset low-energy consumption switching condition may be set in advance according to needs, for example, the duration of the ambient temperature in the target temperature range must reach a certain duration, or the duration must last for a certain duration and the refrigerator is not opened during the duration.
If the refrigerator is detected to meet the low energy consumption switching condition, the refrigerator can be controlled to enter a low energy consumption mode corresponding to the target temperature range. When there are a plurality of target temperature ranges, the ambient temperature is in which temperature range, that is, the refrigerator is controlled to enter the low power consumption mode corresponding to the temperature range. The low energy consumption mode, namely, all parameters of the refrigerator are maintained at a value or a value range which enables the refrigerator to reach the basic refrigeration temperature and simultaneously consumes the lowest energy. For example, when the ambient temperature is 16 ℃, the rotation speed of the refrigerator compressor can achieve the refrigeration effect when 1200 revolutions per minute, and only the power consumption is increased when the rotation speed exceeds 1200 revolutions per minute, so that when the ambient temperature is 16 ℃ or a temperature range including 16 ℃, the rotation speed of the refrigerator compressor can be set at 1200 revolutions per minute; other parameters may be set similarly. Because the required refrigerating capacity of the refrigerator is different under different environmental temperatures, the low energy consumption modes corresponding to different temperature ranges are also different. Wherein, different low energy consumption modes refer to different settings of one or more parameter values.
And if the refrigerator is detected not to meet the low-energy-consumption switching condition, controlling the refrigerator to operate according to the basic program. It should be noted that, if the refrigerator is already in the low energy consumption mode corresponding to the target temperature range, the detection of whether the low energy consumption switching condition is met is not performed.
In this embodiment, by setting a low energy consumption mode in the refrigerator, if it is detected that the ambient temperature is within the target temperature range and the refrigerator meets the preset low energy consumption switching condition, the refrigerator is controlled to enter the low energy consumption mode corresponding to the target temperature range. The low-energy consumption mode corresponding to the target temperature range is set in the refrigerator, and the refrigerator enters the low-energy consumption mode when a certain condition is detected to be met, so that the power consumption of the refrigerator can be reduced through the low-energy consumption mode at the test temperature of the European new standard, and the requirements of improving the energy efficiency and reducing the power consumption at the test temperature of the new standard are met. Compared with the existing schemes of re-developing new products or adjusting the layout of old products, replacing a more efficient compressor or thickening a heat insulation layer, using a VIP vacuum insulation board and the like, the scheme in the embodiment can reach a higher energy consumption level under a new standard without increasing or slightly increasing the cost under the European energy consumption old standard, and simultaneously effectively reduces the overall energy consumption of the refrigerator, thereby ensuring the energy-saving effect and the resource waste of the products, and indirectly improving the competitive advantages of the products.
Further, based on the first embodiment, a second embodiment of the method for controlling a refrigerator according to the present invention is provided, and in this embodiment, before the step S10, the method further includes:
step S20, if the environment temperature is detected to be within the target temperature range, if the duration length of the state that the environment temperature is within the target temperature range is maintained for a first preset duration, and the refrigerator door is not opened and the refrigerator is not set with a quick-freezing function within the first preset duration, the refrigerator meets a preset low-energy-consumption switching condition.
In this embodiment, the preset low energy consumption switching condition may be that the state where the ambient temperature is in the target temperature range needs to last for a first preset time period, and the refrigerator does not pass through the door within the first preset time period, and the quick-freezing function is not set, where the first preset time period may be set as needed, for example, preferably 24 hours, and the quick-freezing function may also be referred to as a quick-cooling function.
If the refrigerator detects that the ambient temperature is within the target temperature range, whether the duration length of the state that the ambient temperature is within the target temperature range is maintained for a first preset time length or not can be detected, and the refrigerator door is not opened and the refrigerator is not set with a quick-freezing function within the first preset time length.
If the duration length of the state that the ambient temperature is within the target temperature range is detected to be maintained for a first preset time, and the refrigerator door is not opened in the first preset time, and the quick-freezing function of the refrigerator is not set, determining that the refrigerator meets a preset low-energy-consumption switching condition, otherwise, determining that the refrigerator does not meet the preset low-energy-consumption switching condition. Specifically, when the refrigerator is not in the low energy consumption mode corresponding to the target temperature range, if the ambient temperature is detected to be in the target temperature range, timing can be started, and if the ambient temperature is detected to be not in the target temperature range, the refrigerator is opened or a quick-freezing function is set to be started in the timing process, timing is restarted until the timing duration reaches a first preset duration, and it can be determined that the preset low energy consumption switching condition is met.
Further, in an embodiment, after the step S10, the method further includes:
and step S30, in the low energy consumption mode, if the refrigerator meets a preset low energy consumption exit condition, controlling the refrigerator to exit the low energy consumption mode.
And when the refrigerator is in the low energy consumption mode, detecting whether the refrigerator meets a preset low energy consumption exit condition. The preset low-energy-consumption exit condition may be set in advance according to needs, for example, a duration length of a state in which the ambient temperature is not in the target temperature range is set to be maintained for a first duration.
And if the refrigerator is detected to meet the low-energy-consumption exit condition, controlling the refrigerator to exit the low-energy-consumption mode, and operating according to the basic program after exiting the low-energy-consumption mode. If it is detected that the low power consumption exit condition is not satisfied, the refrigerator is maintained in the low power consumption mode.
Further, before the step S30, the method further includes:
step S40, in the low energy consumption mode, if the duration of the state in which the ambient temperature is outside the target temperature range is maintained for a second preset duration, and the refrigerator door is opened or the refrigerator is set to have a quick-freezing function, the refrigerator meets a preset low energy consumption exit condition.
In one embodiment, the low-energy-consumption exit condition may be that the duration of the state in which the ambient temperature is not in the target temperature range needs to last for a second preset duration, or the refrigerator opens the door or sets to turn on the quick-freezing function. The second preset time period may be set as required, and is preferably 20 minutes, for example.
Then, when the refrigerator is in the low energy consumption mode, whether the duration length of the state that the ambient temperature is not in the target temperature range is maintained for a second preset duration or not can be detected, and whether the refrigerator is opened or a quick-freezing function is set or not can be detected.
If the duration length of the state that the environment temperature is not in the target temperature range is detected to be maintained for a second preset duration, or the refrigerator is opened, or the quick-freezing function of the refrigerator is set to be started, determining that the refrigerator meets the preset low-energy-consumption exit condition, and otherwise, determining that the refrigerator does not meet the preset low-energy-consumption exit condition. Specifically, when the refrigerator is in the low energy consumption mode, if it is detected that the ambient temperature is not within the target temperature range, timing may be started, and if the timing duration reaches a second preset duration, it may be determined that the low energy consumption exit condition is met, or it is detected that the refrigerator is opened, or it is set that the quick-freezing function is started, and it may be determined that the low energy consumption exit condition is met.
Alternatively, in other embodiments, other low power exit conditions may be set.
Further, based on the first and/or second embodiments, a third embodiment of the refrigerator control method of the present invention is provided, in which the target temperature range is 13 ℃ to 17 ℃, and the low energy consumption mode corresponding to the target temperature range at least satisfies one or more of the following three conditions: the rotating speed of the compressor is 1150-1250 rpm, the frequency conversion board stops supplying power when the compressor stops running, and the defrosting time and the defrosting period are respectively 5-10 minutes and 6-12 hours.
When the refrigerator detects that the ambient temperature is in a temperature range of 13-17 ℃ and meets a low-energy-consumption switching mode, switching to a low-energy-consumption mode corresponding to the temperature range, wherein in the low-energy-consumption mode, the refrigerator at least performs one or more of the following three items: the rotating speed of the compressor is 1150-1250 rpm, the frequency conversion board stops supplying power when the compressor stops running, and the defrosting time and the defrosting period are respectively 5-10 minutes and 6-12 hours. Preferably, the refrigerator is set to perform the three settings in a low power consumption mode, and when the three settings are performed, the refrigerator has the lowest power consumption in the low power consumption mode; preferably, the compressor speed is maintained at 1200 revolutions per minute, i.e. the frequency is maintained at 40 hz; preferably, the defrosting time is 5 minutes, and the defrosting period is 10 hours.
Further, in an embodiment, the target temperature range is 29 ℃ to 33 ℃, and the low energy consumption mode corresponding to the target temperature range at least satisfies one or more of the following three items: the rotating speed of the compressor is 1450 and 1550 revolutions per minute, the frequency conversion board stops supplying power when the compressor stops running, and the defrosting time and the defrosting period are respectively 7-20 minutes and 50-96 hours.
When the refrigerator detects that the ambient temperature is in a temperature range of 29-33 ℃ and meets a low-energy-consumption switching mode, switching to a low-energy-consumption mode corresponding to the temperature range, wherein in the low-energy-consumption mode, the refrigerator at least performs one or more of the following three items: the rotating speed of the compressor is 1450 and 1550 revolutions per minute, the frequency conversion board stops supplying power when the compressor stops running, and the defrosting time and the defrosting period are respectively 7-20 minutes and 50-96 hours. Preferably, the refrigerator is set to perform the three settings in a low power consumption mode, and when the three settings are performed, the refrigerator has the lowest power consumption in the low power consumption mode; preferably, the compressor speed is maintained at 1500 rpm, i.e. the frequency is maintained at 50 hz; preferably, the defrosting time is 7 minutes, and the defrosting period is 56 hours.
The principle is that according to the requirements of the European energy efficiency new standard EN 62552-3:2020 on the power consumption of the refrigerator running at 16 ℃ and 32 ℃, the optimal compressor rotating speed is respectively determined by calculating the heat leakage load of the refrigerator at 16 ℃ and 32 ℃ respectively, and according to the heat load of the refrigerator and the actual performance parameters of the refrigerator running, the refrigerating capacity of the compressor of the refrigerator at different ambient temperatures and different rotating speeds (for example, the optimal rotating speed of 1200 rpm for a certain type of split variable frequency refrigerator is 1500 rpm for the heat load at 16 ℃ and 32 ℃ respectively).
When a refrigerator compressor normally works, a control panel supplies normal current to a compressor frequency conversion plate to enable the frequency conversion plate to be in a normal working state, when the temperature of a refrigerator compartment reaches a set required temperature, a compartment temperature sensor sends a compressor stop control signal to a main control panel, at the moment, the compressor stops working, and meanwhile, the main control panel cuts off the supply of the current to the compressor frequency conversion plate to enable the standby power consumption of the compressor frequency conversion plate to be zero or to reach a minimum state, so that the minimum energy consumption of a refrigerator carrier whole machine is met (for example, the standby power consumption of the refrigerator whole machine is reduced to about 0.5W from 1.3W through the optimization of the working mode of the compressor frequency conversion plate, and the energy efficiency is improved by about 61% in the aspect of refrigerator standby.
The defrosting time and the defrosting period of the freezing evaporator are optimized (because the power of a defrosting heater on the surface of the freezing evaporator is larger, the power of the heater is usually selected between 120W and 220W according to the volume of an air-cooled refrigerator, under the condition that the power of the heater and the power consumed by the heat load of the refrigerator are determined, the defrosting heating time and the defrosting period of the heater directly determine the energy consumption and the energy efficiency grade of the whole refrigerator, and in a standard specified energy consumption test, the maximum defrosting interval delta t at the environment temperature of 32 DEG Cd-maxLess than or equal to 96h, and delta t less than 6h of minimum defrosting intervald-minThe defrosting interval delta t is less than or equal to 12h and at the ambient temperature of 16 DEG Cdf16Is twice Δ tdf32. In view of the requirements of the energy consumption test standards, the defrosting time and the defrosting interval of the heater of the original refrigeration evaporator of the refrigerator are as follows: 28min and 92h at 32 ℃ and 16min and 12h at 16 ℃; in the embodiment of the invention, the defrosting time and the defrosting period of the refrigeration evaporator of the refrigerator are optimized and adjusted to 7min and 56h at the ambient temperature of 32 ℃ and 5min and 10h at the ambient temperature of 16 ℃. After optimization, the power consumption increment in defrosting and recovery periods is as follows: the 115wh before optimization is changed into 25wh after optimization at the ambient temperature of 32 ℃, and the 100wh before optimization is changed into 22wh after optimization at the ambient temperature of 16 ℃. The defrosting of the 175W heater of the refrigeration evaporator and the increase of the power consumption in the recovery period are realized by the improvement of the energy consumption of the whole machine: the ring temperature at 32 ℃ is improved by 78.2 percent, and the ring temperature at 16 ℃ is improved by 78 percent).
Under the European old energy consumption standard, control logics such as variable rotating speed of a compressor, frequency hopping control, frost change of a freezing chamber and the like are adopted. Under the new standard, the compressor only needs to operate at a fixed rotating speed, and only provides the refrigerating capacity needed by balancing the heat leakage load of the foaming layer and the power consumption increment during defrosting and recovery periods. According to the European old energy efficiency standard EN62552-2013, the energy consumption test is carried out at the ambient temperature of 25 ℃ in a freezing chamber with a load bag, and in order to quickly cool an experiment bag to the required experiment temperature and quickly recover and balance the defrosting heat brought in the defrosting process after a freezing evaporator is defrosted in the experiment process, control logics such as the rotating speed of a compressor, frequency hopping control, defrosting of a freezing chamber and the like are generally adopted. The new European energy efficiency standard EN 62552-3:2020, energy consumption test is carried out under the conditions of ambient temperature of 16 ℃ and ambient temperature of 32 ℃ and no-load condition of a freezing chamber, refrigeration capacity provided by the working of a compressor only needs to balance heat leakage load of a foaming layer of a refrigerator, so that the operation of the compressor is not required to adopt logics of variable rotating speed, process frequency hopping and the like to provide refrigeration capacity required by balancing heat leakage load of the foaming layer and power consumption increment in defrosting and recovery periods in the operation and test process and the defrosting and recovery period of a freezing evaporator, excessive cold waste is avoided, and the energy consumption of the whole machine is reduced. The following table 1 shows comparison before and after optimization of control logic parameters under the new and old European energy efficiency standards.

Further, in an embodiment, as shown in fig. 3, a refrigerator performance improvement control module diagram is shown, and as shown in fig. 4, a refrigerator performance improvement control logic diagram under the european new energy efficiency standard is shown. In the present embodiment, a split variable frequency air-cooled refrigerator is taken as an example for explanation.
Specifically, (1) the split variable-frequency air-cooled refrigerator comprises an information acquisition module (a compartment temperature sensor and an environment temperature sensor), a control module and a judgment module;
(2) the refrigerator is preset to run in a low-energy-consumption mode at a specific required ambient temperature of 16 ℃. Namely: the environment temperature is kept between 13 ℃ and 17 ℃ for 24h, and the process is not provided with a door and a quick cooling/quick freezing function.
(3) The refrigerator is preset to run in a low power consumption mode at a specific required ambient temperature of 32 degrees. Namely: the environment temperature is kept between 29 ℃ and 33 ℃ for 24h, and the process is not provided with a door and a quick cooling/quick freezing function.
(4) The low-energy-consumption operation exit mode of the refrigerator at the specific required 16-degree ambient temperature is preset. Namely: when the environment temperature is less than 13 ℃ or more than 17 ℃, the environment temperature exceeds 20min, or the door is opened or a quick cooling/quick freezing/intelligent function is set.
(5) The preset refrigerator is in a low-energy-consumption operation exit mode at the specific required 32-degree ambient temperature. Namely: when the environment temperature is less than 29 ℃ or more than 33 ℃, the environment temperature exceeds 20min, or the door is opened or a quick cooling/quick freezing/intelligent function is set.
After the refrigerator is powered on, the refrigerator is powered on to operate, firstly, the refrigerator environment temperature sensor detects and collects environment temperature information, the compartment temperature sensor collects compartment temperature, and the control system gives a working mode and operation parameters which enable the refrigerator to enter and exit corresponding environment temperature sections and enable the whole refrigerator to have the minimum energy consumption. The refrigerator judges whether to test the power consumption at the ambient temperature of 16 ℃ or 32 ℃ according to the collected ambient temperature information. After the specific environment temperature is selected, the refrigerator continues to operate, whether the refrigerator door is opened in the operation process or not is judged, whether the operation state of the refrigerator is in a quick-freezing or quick-cooling state or not is judged, whether the refrigerator is kept in the state for 24 hours at the selected test environment temperature or not is judged, and if the refrigerator is kept in the state for 24 hours, the control module controls the refrigerator to enter a low-energy-consumption operation mode at the environment temperature. If the environmental temperature changes to 20min in the running process of the refrigerator, the environmental temperature is lower than the lowest temperature of the selected corresponding temperature section or higher than the highest temperature, or the door is opened in the process, the control module controls the refrigerator to exit the power consumption testing mode, judges and updates other environmental temperatures again, the lowest power consumption tested by the refrigerator at the environmental temperature required by the European region and the standard is met, and the energy consumption of the whole refrigerator is also minimum.
