Abstract
One or more embodiments of an automatic switching device and a refrigeration device is provided. The automatic switching device includes an ejection structure including a transmission gear and a rack matching the transmission gear in transmission. The automatic switching device includes a driving device, connected to the transmission gear and used for driving the transmission gear to rotate, so as to drive the rack to extend forwards to open a door body or retract backwards to close the door body. The automatic switching device further includes an auxiliary control device including an inductor arranged on the rack, a first induction switch and a second induction switch.
Claims15
A refrigeration device, comprising:
- a cabinet body;
- a door body connected to the cabinet body;
- and
- an automatic switching system positioned on the cabinet body, and the automatic switching system including:
- an ejection structure including a transmission gear and a rack matching the transmission gear in transmission;
- a driving device, connected to the transmission gear and configured to drive the transmission gear to rotate, so as to drive the rack to protrude to open the door body or to retract to close the door body;
- and
- an auxiliary control device including an inductor, a first induction switch and a second induction switch, the inductor being arranged on the rack, the first induction switch and the second induction switch being connected to the driving device respectively;
- wherein, in operation, if the inductor moves to a position adjacent to the first induction switch, the first induction switch generates a first control signal configured to control the driving device to stop driving so as to cause the door body to remain in an opened state;
- and if the inductor moves to a position adjacent to the second induction switch, the second induction switch generates a second control signal configured to control the driving device to stop driving so as to cause the door body to reset to a closed state,
- the automatic switching system further including:
- a box body installed on the cabinet body, the box body including a first receiving portion and a second receiving portion;
- wherein when installed on the cabinet body:
- the rack, the first induction switch and the second induction switch are positioned in the first receiving portion, a sidewall of the first receiving portion opposite to the door body includes a notch, and the rack extends through the notch to eject the door body;
- the driving device is positioned in the second receiving portion;
- and
- the first induction switch is closer to the notch than the second induction switch.
