The invention content is as follows:
the present invention provides an automatic door opening and closing device for a refrigerator and a working method thereof, which can automatically close a refrigerator door.
The invention adopts the following technical scheme: the utility model provides a refrigerator automatic switch door gear, is including installing step motor, hydraulic cylinder on the box, with step motor fixed connection's guide arm and with the connecting pin of step motor fixed connection in the same place guide arm and hydraulic cylinder connection, a hydraulic cylinder's end-to-end connection has rubber propelling movement piece, and rubber propelling movement piece is installed on the door body, installs infrared inductor in the dead ahead of box.
Further, the door body comprises a left door body and a right door body.
Furthermore, the rubber propelling movement piece is including two altogether, and it sets up respectively on the left door body and the right door body.
Furthermore, the hydraulic oil cylinders comprise two hydraulic oil cylinders which are respectively connected with the rubber pushing blocks in a one-to-one correspondence manner.
Furthermore, the step motor includes two altogether, and it sets up on the box respectively at the interval.
The invention also adopts the following technical scheme: a working method of an automatic door opening and closing device of a refrigerator comprises the following steps:
the method comprises the following steps: the biological identification is input into a refrigerator large-screen system through APP software in a mobile phone, a refrigerator door opening key is clicked, or the mobile phone stands in front of a door body screen, the door body is controlled to be closed through an infrared sensor on a box body, and the door body is controlled to be opened and closed through the refrigerator large-screen biological identification;
step two: the step motor on the upper part of the refrigerator body is operated, and the step motor starts to work to drive the guide rod to move as the guide rod mechanism;
step three: after the guide rod reaches the designated position, the hydraulic oil cylinder starts to push the refrigerator door body away through the rubber pushing block, and the refrigerator door body is completely opened;
step four: after the user takes out the required object, the refrigerator is left for 10 seconds or 30 seconds, and when the infrared sensor on the refrigerator body cannot sense the temperature of the human body, the temperature is transmitted to the stepping motor through program setting, so that the stepping motor rotates reversely, and the door body is closed.
The invention has the following beneficial effects: the automatic door opening and closing device for the refrigerator can realize the automatic closing of the refrigerator door.
Description of the drawings:
fig. 1 is a schematic view of a refrigerator according to the present invention when a door is closed.
Fig. 2 is a schematic view of the refrigerator door of the present invention when opened.
Fig. 3 is a partial schematic view of a refrigerator according to the present invention.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
The invention discloses an automatic door opening and closing device for a refrigerator, which comprises a stepping motor 1 arranged on a box body 7, a guide rod 2 fixedly connected with the stepping motor 1, a hydraulic oil cylinder 4, a connecting pin 8 for connecting the guide rod 2 and the hydraulic oil cylinder 4 together, wherein one tail end of the hydraulic oil cylinder 4 is connected with a rubber pushing block 3, the rubber pushing block 3 is arranged on a door body 6, and an infrared inductor 5 is arranged right in front of the box body 7.
The working method of the automatic door opening and closing device of the refrigerator comprises the following steps:
the method comprises the following steps: the biological identification is input into a refrigerator large-screen system through APP software in a mobile phone, a refrigerator door opening key is clicked, or the mobile phone stands in front of a screen of a door body 6, the door body 6 is controlled to be closed through an infrared sensor 5 on a box body, and the door body 6 is controlled to be opened and closed through the refrigerator large-screen biological identification;
step two: the step motor 1 at the upper part of the refrigerator body 7 is operated, the step motor 1 starts to work, and the guide rod 2 is driven to move as a guide rod mechanism;
step three: after the guide rod 2 reaches a designated position, the hydraulic oil cylinder 4 starts to push the refrigerator door body 6 away through the rubber pushing block 3, and the refrigerator door body is completely opened;
step four: after the user takes out the article of will, leave refrigerator 10 seconds or 30 seconds (the time can have user oneself to set up), when can not the human body temperature through infrared inductor 5 sensing on the refrigerator box 7, set for through the procedure, transmit to step motor 1, make step motor 1 reversal, close door body 6, make housewife can not be for needing oneself switch door vexation again, or child is when opening the refrigerator, the door does not close, also can be in the suggestion, with the automatic closure of the refrigerator door body, it is more humanized.
