A first embodiment of the present invention provides a refrigerator control method based on the hardware configuration shown in fig. 1.
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. Specifically, the refrigerator control method of the embodiment includes:
it should be noted that the refrigerator control method provided by the present invention is applied to a direct frequency refrigerator, and specifically, the direct frequency refrigerator refers to a refrigerator whose compressor is controlled to perform start-stop control based on a temperature acquired by a sensor inside the refrigerator, for example, based on a refrigerator inside temperature acquired by a sensor inside the refrigerator, when it is detected that a refrigerator inside temperature t1 acquired by a sensor reaches a preset start-up temperature t', the compressor is controlled to perform start-up operation to perform refrigeration, and when it is detected that a refrigerator inside temperature t2 acquired by a sensor reaches a preset stop temperature t ", the compressor is controlled to perform stop operation.
In addition, it should be noted that, at present, there are some direct frequency refrigerators only having a refrigerating temperature sensor, an ambient temperature sensor, a defrosting temperature sensor, and the like, and there is no freezing temperature sensor, that is, at present, some direct frequency refrigerators perform start-stop control of the compressor through a temperature collected by the refrigerating temperature sensor or a temperature difference collected by the refrigerating temperature sensor and the ambient temperature sensor, however, since the influence on the temperature of the refrigerating chamber when a load is placed in the refrigerating chamber of the refrigerator is small, the start-stop of the compressor cannot be automatically adjusted by the refrigerating sensor when the load is placed in the freezing chamber of the refrigerator, that is, the start-stop rate of the compressor is basically unchanged, so that the load placed in the freezing chamber cannot be rapidly cooled by freezing, in this embodiment, a refrigerator control method is proposed to solve the above problem, which is specifically:
step S10: acquiring the temperature collected by a defrosting sensor of the refrigerator;
specifically, in the present embodiment, the defrosting sensor is disposed on the freezing chamber evaporator of the refrigerator for collecting the temperature of the evaporator cavity, and preferably, the evaporator of the refrigerator is located at the bottom wall of the freezing liner of the freezing chamber to improve the freezing effect of the freezing chamber of the refrigerator based on the temperature collected by the defrosting sensor.
In addition, in this embodiment, the temperature collected by the defrosting sensor of the refrigerator may be obtained in real time, or the temperature collected by the defrosting sensor of the refrigerator may be obtained at regular time, for example, the temperature collected by the defrosting sensor of the refrigerator may be obtained at 2 hours intervals every day, and in addition, the temperature collected by the defrosting sensor of the refrigerator may be obtained after a preset action is detected, for example, when the door opening and closing action of the refrigerator is detected, the temperature collected by the defrosting sensor of the refrigerator is obtained, or when the load parameter of the freezing chamber of the refrigerator reaches the preset load parameter, specifically, the load parameter refers to the load weight fluctuation range of the freezing chamber of the refrigerator, it should be noted that, in this embodiment, a corresponding weight sensor is arranged at a position of a clamping groove for receiving the partition board inside the refrigerator for detecting the load weight placed on the partition board, it is easy to understand that when the load weight fluctuation amplitude of the freezing chamber of the refrigerator is detected to exceed the preset amplitude, the action of taking out the load and/or putting in the load in the freezing chamber of the refrigerator is indicated, and the temperature collected by the defrosting sensor of the refrigerator is acquired at the moment, so that the freezing effect of the freezing chamber of the refrigerator is improved based on the temperature collected by the defrosting sensor.
In addition, in some embodiments, after the step of acquiring the temperature collected by the defrosting sensor of the refrigerator, the method further includes:
if the temperature does not exceed the preset temperature interval, acquiring the refrigerating temperature acquired by a refrigerating sensor of the refrigerator;
and adjusting a preset start-stop temperature point of a compressor of the refrigerator according to the refrigerating temperature, and controlling the compressor of the refrigerator to operate at the adjusted start-stop temperature point.
Specifically, when the temperature collected by a defrosting sensor of the refrigerator does not exceed a preset temperature interval, the temperature control in a freezing chamber of the refrigerator is in a normal state at present, and the refrigerating temperature collected by a refrigerating sensor of the refrigerator is obtained; the preset start-stop temperature point of the compressor of the refrigerator is adjusted according to the refrigeration temperature, and the compressor of the refrigerator is controlled to operate at the adjusted start-stop temperature point.
Step S20: if the temperature exceeds a preset temperature interval, determining the temperature difference between the temperature and a target temperature;
step S30: and adjusting the preset start-stop temperature point of the compressor of the refrigerator according to the temperature difference, and controlling the compressor of the refrigerator to operate at the adjusted start-stop temperature point.
Specifically, the preset temperature interval refers to a temperature fluctuation interval during normal operation of the refrigerator after the refrigeration temperature control temperature of the refrigerating chamber of the refrigerator is preset, for example, the preset refrigeration temperature of the refrigerating chamber of the refrigerator is-15 degrees, the allowable fluctuation range of the refrigerator is two degrees from top to bottom, the preset temperature interval is-13 degrees to-17 degrees, the target temperature refers to the preset refrigeration temperature control temperature of the refrigerating chamber of the refrigerator, and the preset start-stop temperature point refers to a preset start-stop temperature point set by a user or a developer when the temperature fluctuation of the freezing chamber of the refrigerator is always within an ideal fluctuation interval range.
When the temperature that the sensor that changes frost gathered that detects the refrigerator surpassed preset temperature interval promptly, show that the inside cold air of the walk-in of refrigerator can't carry out rapid cooling to the inside load of refrigerator this moment, need regulate and control the predetermined start-stop temperature point of the compressor of refrigerator promptly to the start-stop rate of the compressor of increase refrigerator, thereby the refrigeration effect of reinforcing refrigerator.
In addition, for convenience of understanding, the start-stop temperature points of the compressor in this embodiment include a start-up temperature point of the compressor and a stop temperature point of the compressor, and the scheme for adjusting the preset start-stop temperature point of the compressor of the refrigerator according to the temperature difference is specifically described as follows:
determining a temperature compensation value of a start-stop temperature point of a compressor of the refrigerator according to the temperature difference;
and adjusting down a preset compressor stop temperature point based on the temperature compensation value and/or adjusting up a preset compressor start temperature point according to the temperature compensation value.
Specifically, in this embodiment, a temperature difference between a temperature collected by a defrosting sensor of the refrigerator and a target temperature is calculated, and then a temperature compensation value of a start/stop temperature point of a compressor of the refrigerator is calculated, where the temperature difference-start/stop temperature point compensation preset function is: t is tSupplement device＝αΔt，tSupplement deviceThe start-stop temperature point compensation temperature is referred to, delta t refers to the temperature difference between the temperature collected by a defrosting sensor of the refrigerator and the target temperature, and alpha is a conventional coefficient.
In this step, it should be noted that the start-stop temperature point of the compressor includes a compressor start-up temperature point and a compressor stop temperature point, that is, when it is detected that the temperature inside the refrigerator reaches the compressor start-up temperature point, the compressor is controlled to start up to operate to perform refrigeration, and when it is detected that the temperature inside the refrigerator reaches the compressor stop temperature point, the compressor is controlled to stop operating, so that the operation is cyclically repeated to perform refrigeration regulation and control of the refrigerator, where the compressor start-up temperature point is higher than the compressor stop temperature point.
Therefore, in this embodiment, when the temperature collected by the defrosting sensor of the refrigerator is too high, the preset on-off temperature point of the compressor needs to be adjusted to increase the on-off rate of the compressor of the refrigerator, that is, the preset on-off temperature point of the compressor is adjusted downward based on the temperature compensation value and/or the preset on-off temperature point of the compressor is adjusted upward based on the temperature compensation value. For example, if the preset compressor stop temperature point is-15 degrees, the preset compressor start-up temperature point is-12 degrees and the temperature compensation value is 2 degrees, the preset compressor stop temperature point is adjusted down to-17 degrees and the preset compressor stop temperature point is adjusted up to-13 degrees, so that the compressor on-time rate of the refrigerator is increased and the refrigerating effect of the refrigerating chamber of the refrigerator is improved.
In addition, in some embodiments, after the step of adjusting the preset start/stop temperature point of the compressor of the refrigerator according to the temperature difference and controlling the compressor of the refrigerator to operate at the adjusted start/stop temperature point, the method further includes:
recording the current adjustment time point of the start-stop temperature point, and accumulating the running time of the compressor of the refrigerator running at the adjusted start-stop temperature point through a timer of the refrigerator;
and when the operation time reaches the preset time, controlling the starting and stopping temperature point of the compressor of the refrigerator to be adjusted back to the preset starting and stopping temperature point.
Specifically, the preset time length refers to a time length for limiting the refrigerator to operate at the adjusted start-stop temperature point, and it is easy to understand that when the compressor of the refrigerator operates at the adjusted start-stop temperature point for a long time, the temperature inside the refrigerator is lower than the temperature set by the user and the power consumption of the refrigerator is increased.
It should be understood that the above is only an example, and the technical solution of the present invention is not limited in any way, and those skilled in the art can make settings based on needs in practical applications, and the settings are not listed here.
According to the scheme, the temperature acquired by the defrosting sensor of the refrigerator is acquired; if the temperature exceeds a preset temperature interval, determining the temperature difference between the temperature and a target temperature; according to the invention, the start-stop temperature point of the compressor of the refrigerator is adjusted according to the temperature acquired by the defrosting sensor of the refrigerator, so that the load cooling speed of the freezing chamber of the refrigerator is increased, the technical problem of slow load cooling of the freezing chamber of the refrigerator caused by controlling the start-stop of the compressor by using the refrigeration sensor in the prior art is solved, and the refrigeration effect of the refrigerator is further improved.
Further, based on the first embodiment of the refrigerator control method of the present invention, a second embodiment of the refrigerator control method of the present invention is proposed.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a refrigerator control method according to the present invention;
the second embodiment of the refrigerator control method is different from the first embodiment of the refrigerator control method in that the step of adjusting the preset on-off temperature point of the compressor of the refrigerator according to the temperature difference and controlling the compressor of the refrigerator to operate at the adjusted on-off temperature point further comprises:
step S301: judging whether a defrosting heater of the refrigerator is in a working cycle or not;
step S302: and if the defrosting heater of the refrigerator is not in the working period, adjusting the preset start-stop temperature point of the compressor of the refrigerator according to the temperature difference, and controlling the compressor of the refrigerator to operate at the adjusted start-stop temperature point.
Specifically, the defrosting heater of the refrigerator is arranged at the lower part of the evaporator of the refrigerator, and it should be noted that the defrosting heater of the direct frequency refrigerator is operated periodically at present to avoid the refrigerator from frosting seriously, so that the defrosting heater of the refrigerator is arranged at the lower part of the evaporator of the refrigerator, and the defrosting sensor is arranged on the freezing chamber evaporator of the refrigerator and is used for collecting the temperature of the cavity of the evaporator, therefore, when the defrosting heater works, the temperature collected by the defrosting sensor of the refrigerator is greatly increased.
Therefore, in this embodiment, in order to avoid erroneous judgment of the control system of the refrigerator due to operation of the defrosting heater, after the temperature is detected to exceed the preset temperature range, it is first determined whether the defrosting heater of the current refrigerator is in the working period, if the defrosting heater of the current refrigerator is not in the working period, the preset start-stop temperature point of the compressor of the refrigerator is adjusted based on the temperature difference, and if the defrosting heater of the current refrigerator is in the working period, it is indicated that the current temperature rise is caused by operation of the defrosting heater, the refrigerator is controlled to operate according to the preset start-stop temperature point, so that the temperature control accuracy of the refrigerator is improved.
It should be understood that the above is only an example, and the technical solution of the present invention is not limited in any way, and those skilled in the art can make settings based on needs in practical applications, and the settings are not listed here.
According to the scheme, whether the defrosting heater of the refrigerator is in the working cycle or not is judged; if the defrosting heater of the refrigerator is not in the working period, the preset start-stop temperature point of the compressor of the refrigerator is adjusted according to the temperature difference, and the compressor of the refrigerator is controlled to operate at the adjusted start-stop temperature point, so that the temperature control accuracy of the refrigerator is improved.
Further, based on the first embodiment of the refrigerator control method of the present invention, a third embodiment of the refrigerator control method of the present invention is proposed.
Referring to fig. 4, fig. 4 is a flowchart illustrating a third embodiment of a refrigerator control method according to the present invention;
the third embodiment of the refrigerator control method is different from the first embodiment of the refrigerator control method in that the step of adjusting the preset on-off temperature point of the compressor of the refrigerator according to the temperature difference and controlling the compressor of the refrigerator to operate at the adjusted on-off temperature point further comprises:
step S303: acquiring the last adjustment time point of the starting and stopping temperature point of a compressor of the refrigerator;
step S304: determining a time difference between a current time point and the last adjustment time point;
step S305: and if the time difference is larger than the preset time difference, adjusting the preset start-stop temperature point of the compressor of the refrigerator according to the temperature difference, and controlling the compressor of the refrigerator to operate at the adjusted start-stop temperature point.
Specifically, the preset time difference refers to a time interval between two adjacent adjustment actions for limiting the adjustment of the preset start-stop temperature point of the compressor of the refrigerator, and if the preset time difference is 48 hours, the preset start-stop temperature point of the compressor of the refrigerator can be adjusted again only after the shortest interval of 48 hours after the preset start-stop temperature point of the compressor of the refrigerator is currently adjusted, and preferably, in the present embodiment, the preset time difference is 24 hours.
In this step, it should be noted that, in order to reduce power consumption of the refrigerator, in this embodiment, the start-up rate of the compressor of the refrigerator is controlled, specifically, when it is detected that a preset start-stop temperature point of the compressor of the refrigerator needs to be adjusted currently, a last adjustment time point of the start-stop temperature point of the compressor of the refrigerator is obtained first, and it is easy to understand that, in this embodiment, the refrigerator is provided with a clock module, and the clock module is used for recording time information of each operation of internal components of the refrigerator, such as start-up time point information and stop time point information of the compressor of the refrigerator, so that a last adjustment time point of the start-stop temperature point of the compressor of the refrigerator is obtained by the clock module of the refrigerator to determine a time difference from the last adjustment time point currently, for example, the last adjustment time point is 2020/05/18; 18: 00, current time point 2020/05/19; 16: and 00, the time difference is 22 hours, namely the preset starting and stopping temperature point of the compressor of the refrigerator is adjusted before 22 hours, after the time difference is obtained, if the time difference is greater than the preset time difference, the preset starting and stopping temperature point of the compressor of the refrigerator can be adjusted currently, if the time difference is not greater than the preset time difference, the current interval time from the last adjustment is too short, if the time difference is adjusted again, the power consumption of the refrigerator is increased, and the compressor of the refrigerator is continuously controlled to operate at the preset starting and stopping temperature point.
It should be understood that the above is only an example, and the technical solution of the present invention is not limited in any way, and those skilled in the art can make settings based on needs in practical applications, and the settings are not listed here.

step S307: and if the current refrigerator does not have door opening and closing actions, adjusting the preset starting and stopping temperature point of the compressor of the refrigerator according to the temperature difference, and controlling the compressor of the refrigerator to operate at the adjusted starting and stopping temperature point.
In this step, it is easy to understand that, since the temperature in the refrigerating chamber of the refrigerator is generally lower than the ambient temperature of the environment where the refrigerator is located, when the door of the freezing chamber of the refrigerator is in an open state, the temperature collected by the defrosting sensor of the refrigerator may also be greatly increased due to the influence of the ambient temperature of the environment where the refrigerator is located.
Therefore, in this embodiment, in order to avoid erroneous determination of the control system of the refrigerator, after detecting that the temperature exceeds the preset temperature range, it is first determined whether a door opening and closing action exists in the current refrigerator, if the door opening and closing action does not exist in the current refrigerator, the preset opening and closing temperature point of the compressor of the refrigerator is adjusted according to the temperature difference, if the door opening and closing action exists in the current refrigerator, it is determined whether the time interval between the door opening action and the door closing action of the refrigerator exceeds the preset time interval, if the preset time interval is not exceeded, the preset opening and closing temperature point of the compressor of the refrigerator is adjusted according to the temperature difference, furthermore, in order to further improve the temperature control accuracy of the refrigerator, when the preset time interval is not exceeded, the ambient temperature collected by the ambient sensor of the refrigerator is obtained, and when it is detected that the ambient temperature is increased due to an excessive external ambient temperature, if the ambient temperature is not higher than the temperature threshold, the preset starting and stopping temperature point of the compressor of the refrigerator is adjusted according to the temperature difference, and therefore the temperature control accuracy of the refrigerator is improved.
It should be understood that the above is only an example, and the technical solution of the present invention is not limited in any way, and those skilled in the art can make settings based on needs in practical applications, and the settings are not listed here.
According to the scheme, whether door opening and closing actions exist in the refrigerator at present is judged; if the current refrigerator does not have door opening and closing actions, the preset starting and stopping temperature point of the compressor of the refrigerator is adjusted according to the temperature difference, and the compressor of the refrigerator is controlled to operate at the adjusted starting and stopping temperature point, so that the temperature control accuracy of the refrigerator is improved.
