Detailed Description
The present invention first provides a control method of a refrigerator including a human body sensing device for sensing human body information. Fig. 1 is a schematic flowchart of a refrigerator control method according to a first embodiment of the present invention. Referring to fig. 1, the control method of the present invention includes:
step S20, determining the target time interval of the current time when the refrigerator is in the power-on state;
step S30, determining a target sensing area of the human body sensing device according to the target time interval;
step S40, controlling the human body induction device to induce whether a human body exists in the target induction area;
and step S50, lighting the display screen of the refrigerator when a human body exists in the target sensing area.
The applicant realizes that the light state in different time periods is different, the activity state of the human body in different time periods is different, and the use requirement of the refrigerator is different. For example, in the daytime, the human body frequently moves indoors, and the refrigerator is intentionally opened only when the human body is very close to the refrigerator; in the evening, the brightness state is not good, and if a user needs to turn on the refrigerator, the user needs to turn on the lamp first and can turn on the refrigerator after approaching the refrigerator; at night, the activity of human body in the room is rare, and the refrigerator is hardly required to be opened. The need for light is greater for the active person during both the evening and the late night hours.
Therefore, according to the refrigerator control method, different sensing areas of the human body sensing device are designed according to different time intervals, the target sensing area of the human body sensing device is automatically determined according to the target time interval of the current time, so that the human body sensing device is controlled to sense whether a human body exists in the determined target sensing area, and the display screen of the refrigerator is lightened only when the human body exists in the target sensing area. Therefore, different human body induction areas corresponding to different time intervals can be automatically matched, so that the display screen is lightened at different occasions, manual setting or adjustment of a user is not needed, and the intelligent degree of the refrigerator is improved.
Meanwhile, the display screen lighting purpose in different time intervals is different, for example, the display screen lighting in the daytime is convenient for a user to operate the refrigerator, and the display screen lighting in the evening and the night can provide illumination for the user, so that different using requirements of the user on the display screen of the refrigerator in different time intervals are met, and the functions of the refrigerator are enriched.
In particular, the human body sensing device is preferably a radar human body sensing device, the sensing distance of the radar human body sensing device can be adjusted, and therefore the sensing area of the radar human body sensing device can also be adjusted. In some alternative embodiments, the human body sensing device may also be other sensing devices capable of adjusting the sensing area.
Fig. 2 is a schematic flowchart of a refrigerator control method according to a second embodiment of the present invention. In some embodiments, the step of determining the target time interval at which the current time is located may specifically include:
step S211, acquiring the current time; and
in step S212, the obtained current time is matched with a plurality of preset time intervals to determine a target time interval where the current time is located.
Specifically, a clock unit for recording time in real time may be set on the refrigerator, and the current time recorded by the clock unit is obtained, and the current time is in which time interval, which time interval is the target time interval.
Fig. 3 is a schematic flowchart of a refrigerator control method according to a third embodiment of the present invention. In other embodiments, the step of determining the target time interval at which the current time is located may specifically include:
step S221, acquiring a light intensity signal of the environment where the refrigerator is located; and
step S222, determining a target time interval of the current time according to the matching relationship between the light intensity signal and the time interval.
Specifically, a light sensor may be disposed on the refrigerator, and the light sensor is used to detect a light intensity signal of an environment where the refrigerator is located. Different light intensity signals correspond to different time intervals, for example, when the light intensity signals are stronger, the light intensity signals correspond to the daytime; when the light intensity signal is weaker, the night corresponds to. The target time interval at which the current time is located can thus be determined from the current light intensity signal.
Fig. 4 is a schematic flowchart of a refrigerator control method according to a fourth embodiment of the present invention. In some embodiments, the step S30 of determining the target sensing area of the human body sensing device according to the target time interval may specifically include:
step S310, determining a target sensing distance of the human body sensing device according to the target time interval; and
in step S320, a sector area with the human body sensing device as a center and the target sensing distance as a radius is determined as a target sensing area.
Specifically, when the position of the human body sensing device is fixed, the target sensing region may be located at the front side of the human body sensing device, and the central angle of the sector region may be any angle value between 60 ° and 180 °. When the human body induction device is movable, the target induction area can be all ranges scanned by the human body induction device within the target induction distance, at the moment, the central angle of the fan-shaped area can be close to 360 degrees, and when the central angle is equal to 360 degrees, the target induction area is a circular area.
In some embodiments, a plurality of time intervals divided according to the activity frequency of the human body in the room are preset in the refrigerator. Namely, the human body activities corresponding to different time intervals have different frequency degrees. Furthermore, the target sensing distance corresponding to the time interval is in inverse correlation with the activity frequency of the human body in the time interval. That is to say, the higher the frequency of human activities, the smaller the target sensing distance corresponding to the time interval, and only when the human body is very close to the refrigerator, the human body sensing device can sense the human body, so as to light the display screen. Correspondingly, the target sensing distance corresponding to the time interval with the lower human activity frequency degree is larger, and when the human body is far away from the refrigerator, the human body sensing device can sense the human body so as to light the display screen.
The applicant realizes that when human activities are frequent, the human activities are easy to get close to the refrigerator, but the refrigerator does not need to be operated, and the problem that the energy consumption is increased and the user experience is poor due to frequent lighting of the display screen can be avoided by setting the sensing distance of the human body sensing device to be smaller. When human activity is not frequent, evening usually, the user is less to the user demand of refrigerator this moment, can just detect the human body and light the display screen in the department far away with the great of human induction system's response distance setting this moment, provides the illumination for the user through the display screen, saves the trouble of turning on the light.
In other embodiments, the time interval may also be subdivided according to the time period itself. For example, a daytime activity time interval, a nighttime activity time interval and a sleeping time interval can be preset in the refrigerator. The target sensing distances corresponding to the daytime activity interval, the nighttime activity interval and the sleeping time interval are increased in sequence. That is to say, the target sensing distance in the activity time interval in the daytime is the smallest, and the target sensing distance corresponding to the sleep time interval is the largest. As mentioned above, in the activity time interval in daytime, the human body is frequently moved and is easy to get close to the refrigerator, but the refrigerator is not necessarily required to be operated, and the problem of increased energy consumption and poor user experience caused by frequent lighting of the display screen can be avoided by setting the sensing distance of the human body sensing device to be smaller. In the sleep time interval, the activity of the human body is only limited to the operation of needing illumination such as going up the toilet, drinking water, and at this moment, the human body induction system just can respond to the human body far away and light the display screen automatically, can provide light for the user, does not need the user to turn on the light. For activity time interval at night, the activity of the human body near the refrigerator is relatively frequent, however, the refrigerator is usually in a kitchen, a corner and other dark places, when the user is near the refrigerator, the display screen is lighted to illuminate the area near the refrigerator for the user, the intelligent sense is strong, and the use experience of the user is improved.
In a specific embodiment, the daytime active time interval may be from 7 am to 7 pm, the evening active time interval may be from 7 pm to 10 pm, and the sleep time interval may be from 10 pm to 7 next day. In other embodiments, the daytime active time interval, the nighttime active time interval, and the sleeping time interval may also be set or adjusted according to the actual work and rest habits of the user.
Fig. 5 is a schematic flowchart of a refrigerator control method according to a fifth embodiment of the present invention. In some embodiments, the human body sensing device is movably disposed at a front side of the refrigerator. In these embodiments, the control method of the present invention further includes:
and step S10, after the refrigerator is powered on, controlling the human body induction device to rotate back and forth within a preset angle range in a preset direction according to a preset time period.
Therefore, whether a human body exists in the target induction area can be sensed more comprehensively, dead angles which cannot be sensed are avoided, and the accuracy of the refrigerator for sensing the human body is improved.
Specifically, the preset time period may be set to be small enough to correspond to the human body sensing device continuously rotating in real time when the time period is small enough. The preset direction may be a horizontal direction, i.e. from left to right and then from right to left. The preset angle range may be specifically set according to a location where the refrigerator is located, for example, when the refrigerator is embedded in a wall, the rear side and the lateral sides of the refrigerator may not be present, and in this case, the preset angle range may be in a range of 180 °. For another example, when the refrigerator is placed against a wall with both lateral sides open. Only the rear side of the refrigerator is impossible to exist, and at this time, the preset angle range is greater than 180 °.
It is understood that the above step S10 may occur before step S20, or between step S30 and step S40, in order to more fully sense the human body.
Fig. 6 is a schematic flowchart of a refrigerator control method according to a sixth embodiment of the present invention. In some embodiments, the control method of the present invention further comprises:
step S60, when the human body induction device induces the existence of the human body in the target induction area, the human body induction device is controlled to track the human body; and
and step S70, when the human body sensing device senses that the position of the human body does not change within the first preset time, the display screen is turned off, and the display screen continues to rotate within the preset angle range in the preset direction according to the preset time period.
Specifically, the first preset duration may be any duration value within 3-10 min. That is, when the position of the human body is not moved for a long time, the human body may be in a sleeping state or other states that do not require the refrigerator to perform any operation, and at this time, the turning-off of the display screen can reduce energy consumption, and the human body sensing device continues to rotate so as to detect the activities of other human bodies in time.
Fig. 7 is a schematic flowchart of a refrigerator control method according to a seventh embodiment of the present invention. In some embodiments, the control method of the present invention further comprises:
and step S80, stopping rotating when the human body sensing device does not detect the human body continuously within a second preset time period.
Specifically, the second preset duration may be any duration value within 0.5 to 2 hours. That is, after the human body is not detected for a long time, the user is not at home or has fallen asleep by default, and the energy consumption can be saved by stopping the rotation of the human body sensing device.
In some embodiments, the refrigerator may include a cabinet and a door, and the human body sensing device may be telescopically disposed at a front side of the cabinet or the door. The control method of the present invention further includes:
after the refrigerator is powered on, the human body induction device is controlled to extend out of the refrigerator body or the door body;
and after the refrigerator is powered off, the human body sensing device is controlled to retract into the refrigerator body or the door body.
Therefore, the normal use of the human body induction device can be ensured, and the beauty of the refrigerator can be kept.
It is understood that, in some embodiments, the control method of the present invention may include step S10, step S221, step S222, step S310, step S320, step S40, step S50, step S60, step S70, and step S80 at the same time. In other embodiments, the control method of the present invention may include step S10, step S211, step S212, step S310, step S320, step S40, step S50, step S60, step S70, and step S80.
