Further, the mounting base 215 and the first sensor 211, the second sensor 212 and the display screen 216 disposed on the mounting base 215 are disposed behind the glass on the front side of the refrigerator door 200, i.e. between the door 200 and the glass on the front side of the door 200, so as to protect the first sensor 211, the second sensor 212 and the display screen 216.
Preferably, both the first sensor 211 and the second sensor 212 are capacitive sensors. The capacitive sensor has the advantages of good temperature stability, simple structure, easy manufacture and the like, can ensure higher manufacturing precision, has very small required acting energy due to very small electrostatic attraction between charged polar plates, can be manufactured very thin, namely, has very light weight, and therefore, has very high natural frequency, short dynamic response time and higher sensitivity, and is suitable for being applied to a refrigerator.
Preferably, the user can adjust the threshold values of the first sensor 211 and the second sensor 212 through the singlechip 213, namely, adjust the sensitivity of the two capacitance sensors, so that when the hand or other parts of the body, such as the elbow, of the human body are contacted with or are very close to the sensors, the capacitance sensors can sense the change of the capacitance, and when the change value exceeds the threshold value set in advance, a trigger signal is sent to the singlechip 213.
Further, the sensor provided by the embodiment of the invention is not limited to only the first sensor 211 and the second sensor 212, but may be provided with a plurality of sensors, when the door is automatically opened and closed in the whole sliding triggering process, the plurality of sensors are sequentially triggered in sequence in a sliding manner, so that the situation of false touch can be better avoided, and the probability of the door body 200 being opened due to false touch is greatly reduced because the plurality of sensors are required to be continuously triggered.
In order to make the user more intuitively know whether the sensor is triggered, as shown in fig. 3, the embodiment of the present invention further includes an indicator lamp 214, where the indicator lamp 214 is connected to the singlechip 213. After the singlechip 213 receives the trigger signals sent by the first sensor 211 and the second sensor 212, the singlechip 213 controls the indicator lamp 214 to be lightened, and the user can know that the trigger is successful after seeing that the indicator lamp 214 is lightened.
The embodiment of the invention also provides a control method for automatically opening and closing the door of the refrigerator, as shown in fig. 2 and 4, comprising the following steps: detecting whether the first sensor 211 is triggered; when the first sensor 211 is triggered, judging whether the duration time for triggering the first sensor 211 exceeds a preset time; when the duration exceeds a preset time, the triggering is judged to be valid, the ejection actuator 110 is controlled to push the door body 200 to be separated from the box body 100, and when the duration does not exceed the preset time, the triggering is judged to be invalid.
According to the control method for the refrigerator with the automatic door opening and closing function, when the food needing to be stored and taken out is small, the first sensor 211 on the door body 200 is triggered, when the duration of triggering the first sensor 211 exceeds the preset time, the ejection actuator 110 pushes the door body 200 to be separated from the refrigerator body 100, and after the door body 200 is separated from the refrigerator body 100, the door body 200 is opened and closed only by small force, so that a user can manually perform the subsequent opening and closing actions of the door body 200, when the food needing to be stored and taken out is small, the time for opening the door body 200 is shortened, the outside hot and humid air is prevented from entering the refrigerator, and the fresh-keeping effect of the food is improved.
Preferably, the preset time for triggering the first sensor 211 is greater than or equal to 20ms. To prevent false touches, the duration of triggering the first sensor 211 may be set to be greater than 20ms, and the triggering is successful.
In addition, as shown in fig. 2 and 4, it is detected whether the first sensor 211 and the second sensor 212 are both triggered; when the first sensor 211 and the second sensor 212 are triggered, judging whether the triggering sequence of triggering the first sensor 211 and the second sensor 212 accords with a preset sequence; when the triggering sequence accords with the preset sequence, the triggering is judged to be effective, the ejection actuator 110 is controlled to push the door body 200 to be separated from the box body 100, and then the door opening and closing actuator 120 is used for controlling the door body 200 to be completely opened; and when the triggering sequence does not accord with the preset sequence, judging that the triggering is invalid. The user can select according to the use condition, only trigger the first sensor 211, or trigger the first sensor 211 and the second sensor 212 successively, so as to realize two different modes of opening the door body 200, namely, only separate the door body 200 from the box body 100 through the ejection actuator 110, then manually control the door body 200 to open, or separate the door body 200 from the box body 100 through the ejection actuator 110, then open the full-automatic door opening process of the door body 200 through the door opening actuator 120, so that the user can select different door opening modes according to the food material to be accessed, and the user experience is facilitated to be improved.
Preferably, the triggering sequence is to trigger the first sensor 211 first, trigger the second sensor 212 later, or trigger the second sensor 212 first, trigger the first sensor 211 later. The sequence is only required to be set in advance, and the automatic door opening can be triggered as long as the triggering sequence is the same as the preset sequence.
It should be noted that, when in use, a user can trigger successively by touching the two sensors successively, that is, touching the first sensor 211 first and then touching the second sensor 212, and the mode can trigger the automatic opening of the door 200 successfully on the premise of meeting the preset rule; the two sensors can also be triggered in a sliding manner, and the sequence of triggering the two sensors in the sliding direction is the same as the preset sequence.
Preferably, the time interval for triggering the first sensor 211 and the second sensor 212 ranges from 30ms to 1500ms. In order to avoid the situation of false touch, the time interval for triggering the two sensors needs to be within the time range, and the singlechip 213 can only receive the signal of successful triggering.
In addition, in the automatic door opening and closing refrigerator provided by the embodiment of the invention, in the door closing process, because the door closing is not needed to overcome the self-suction force of the door body 200, only a small force is needed to realize the door closing, so that a user can close the door in a manual control manner, and can also close the door in a manner of triggering the first sensor 211 and the second sensor 212 through the singlechip 213, for example, the door closing signal is set in the order opposite to the triggering order when the door is opened, and the time interval for triggering the two sensors also can meet the time range.
It should be noted that, in the ejection actuator 110 provided in the embodiment of the present invention, the existing technology disclosed in the market may be adopted, for example, a motor is used as a driving element, a driving gear is provided at an output end of the motor, a rack is meshed with the driving gear, the rack is fixedly connected with a push rod, the push rod is slidably connected with the box body 100, and the push rod corresponds to an end of a top surface of the door body 200 far away from the rotating shaft, and a movement direction of the rack is perpendicular to a surface of the box body 100 opposite to the door body 200, so that the driving gear drives the rack to move through rotation of the motor, and meanwhile, the push rod slides to contact with the door body 200 through the push rod, so that the door body 200 can be pushed to be separated from the box body 100.
For the pull-out door body 200, the ejection actuator 110 is only required to be arranged at the position corresponding to the middle part of the door body 200, so that the door body 200 is uniformly stressed when the door body 200 is pushed, and the door body 200 is opened easily.
