Example one
The embodiment provides a refrigerator control method based on ultrasonic waves, wherein a plurality of ultrasonic sensors facing to the front area of the refrigerator are arranged on the refrigerator, and as shown in fig. 3, the method comprises the following steps:
and S10, periodically detecting the existence of the object meeting the preset condition in the preset range through the ultrasonic sensor.
Specifically, a plurality of ultrasonic sensors facing to the front area of the refrigerator are arranged on the refrigerator, so that objects in the front area of the refrigerator can be detected through the plurality of ultrasonic sensors. In this embodiment, as shown in fig. 1, the number of the ultrasonic sensors is 5, the 5 ultrasonic sensors are respectively recorded as a first ultrasonic sensor 1, a second ultrasonic sensor 4, a third ultrasonic sensor 5, a fourth ultrasonic sensor 6 and a fifth ultrasonic sensor 7, wherein the first ultrasonic sensor 1 is arranged at the top of the refrigerator frame, the second ultrasonic sensor 4 is located at the upper left of the refrigerator cold storage door body, the third ultrasonic sensor 5 is located at the lower right of the refrigerator cold storage door body, the fourth ultrasonic sensor 6 is located at the left freezing chamber of the refrigerator, and the fifth ultrasonic sensor 7 is located at the bottom of the refrigerator frame. Therefore, the detection range of the ultrasonic sensor can be enlarged through the 5 ultrasonic sensors, and the detection accuracy is improved.
Further, each ultrasonic sensor may be configured to be an object in an area with a preset distance from the refrigerator, that is, each ultrasonic sensor corresponds to one detection range, and a union of the detection ranges corresponding to the ultrasonic sensors forms the monitoring range. In this embodiment, in order to improve the detection accuracy of each ultrasonic sensor, a monitoring range formed by the preset distance corresponding to each ultrasonic sensor may be greater than the preset range, that is, the preset distance corresponding to the monitoring range is greater than the preset distance corresponding to the preset range, for example, the monitoring range is 100cm for a large preset distance, and the preset distance corresponding to the preset range is 60 cm. Of course, the preset range is a union of detection ranges formed by the ultrasonic sensors at preset distances corresponding to the preset range. In the embodiment, the preset range is smaller than the monitoring range, so that forced cooling starting caused by objects passing through the refrigerator can be avoided, and the accuracy of forced cooling starting is improved. Of course, in other embodiments of this embodiment, the listening range may be equal to the preset range.
Exemplarily, as shown in fig. 4, the periodically detecting whether an object appears in the preset range by the ultrasonic sensor specifically includes:
s11, periodically detecting whether an object appears in a first preset time length in a preset range by using an ultrasonic sensor;
s12, when an object appears in the preset range, acquiring the appearance time length of the object, and judging whether the appearance time length reaches a second preset time length so as to judge whether the object meets the preset condition.
Specifically, the periodicity refers to that the ultrasonic sensor detects once every fixed time interval. The fixed time is a preset setting, for example, 3 s. That is, the ultrasonic sensor is restarted after being stopped for a fixed time, and whether an object satisfying a preset condition appears within a preset range is detected. In this embodiment, the ultrasonic sensor continues to operate for a first preset time after being started, stops operating after the first preset time, and starts again after stopping operating for a fixed time, and so on. Wherein the first preset time period may be 10 s.
Further, the second preset duration is a duration of continuously detecting the occurrence of the object, that is, the preset condition is that the duration of detecting the existence of the object in the preset range reaches the second preset duration. Correspondingly, when an object appears in the preset range, the appearance duration of the object is obtained, and whether the appearance duration reaches a second preset duration is judged, so as to judge whether the object meets the preset conditions specifically comprises the following steps:
when an object appears in a preset range, acquiring the appearance duration of the object continuously detected by each ultrasonic sensor;
and detecting whether the appearance time corresponding to the ultrasonic sensor reaches a second preset time so as to judge whether the object meets the preset condition.
Specifically, the fact that the detected object occurrence duration reaches a second preset duration means that any one of the plurality of ultrasonic sensors continuously detects that the object occurrence duration reaches the second preset duration. That is, the appearance duration of the object refers to the duration in which one ultrasonic sensor continuously detects the object, so that the starting of the refrigeration device due to the physical temporary stay can be reduced, and the starting accuracy of the refrigeration device is improved.
And S20, controlling a refrigeration device configured in the refrigerator to start and monitoring the temperature in the refrigerator when an object meeting a preset condition exists in the preset range.
In particular, the refrigeration device is a device 11 configured for refrigerating the refrigerator itself, as shown in fig. 2. In this embodiment, the refrigeration device is a compressor. That is to say, when the preset scope has the object that satisfies the preset condition, the control compressor starts, as long as the refrigerator presets the scope in the object that satisfies the preset condition, control compressor starts promptly, and can't monitor whether the refrigerator door is opened to can avoid the refrigerator door to open when leading to the refrigerator door to open by force, avoid the refrigerator door to open and cause the temperature in the refrigerator to be less than preset temperature, thereby improved the freshness preservation of refrigerator.
Further, in an embodiment of the present invention, as shown in fig. 5, when there is an object meeting a preset condition in the preset range, controlling a refrigeration device configured in the refrigerator to start and monitoring a temperature in the refrigerator specifically includes:
s21, when the object meeting the preset condition exists in the preset range, acquiring the working state of a refrigeration device configured in the refrigerator;
and S22, when the working state is in an idle state, controlling the refrigeration device to start, and setting the working efficiency of the refrigeration device to be a preset working efficiency.
Specifically, the preset working efficiency is preset so that the refrigeration device is lowered to a preset temperature within a preset time. That is, the cooling device may be lowered to a preset temperature for a preset time when the preset operation efficiency is operated. The preset time is, for example, 1 minute. The preset temperature is determined according to the configuration temperature of the refrigerating chamber of the refrigerator, and is lower than the configuration temperature of the refrigerating chamber by 2 degrees. For example, when the configured temperature of the refrigerating chamber of the refrigerator is 5 degrees, the preset temperature is 3 degrees, that is, the refrigerating device reduces the temperature of the refrigerator to 3 degrees at 1 minute after configuring the preset operation efficiency.
In addition, when detecting an object satisfying a preset condition, a refrigeration device of the refrigerator may be in an occupied state, and the refrigerator needs to determine a preset work efficiency for a current situation of the refrigerator. Correspondingly, when the object meeting the preset condition exists in the preset range, controlling the starting of the refrigeration device configured in the refrigerator and monitoring the temperature in the refrigerator further comprises:
when the working state is an occupied state, acquiring the current temperature of the refrigerator and preset refrigerating time;
and calculating the working efficiency of the refrigerating device according to the current temperature, the preset temperature and the preset refrigerating time, and setting the calculated working efficiency as the working efficiency.
Specifically, the occupied state refers to that the refrigeration device is in operation, in addition, the current temperature, the preset time length and the preset temperature of the refrigerating chamber of the refrigerator need to be obtained, the working efficiency required for reducing the temperature of the refrigerating chamber of the refrigerator by the degree of the difference between the current temperature and the preset temperature within the preset time can be determined according to the current temperature, the preset time length and the preset temperature, and the refrigeration device is controlled to work with the calculated working efficiency, so that the temperature of the refrigerating chamber of the refrigerator can be reduced by the preset temperature after the preset time length.
And S30, controlling the refrigeration device to stop when the monitored temperature reaches a preset temperature, wherein the preset temperature is lower than the working temperature of the refrigerator configured with the refrigerator to stop.
