Abstract
The present disclosure provides an automatic switching device and a refrigeration device. The automatic switching device comprises: an ejection structure, comprising a transmission gear and a rack matching the transmission gear in transmission; 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; and an auxiliary control device comprising an inductor arranged on the rack, a first induction switch and a second induction switch.
Claims18
An refrigeration device, comprising:
- a cabinet body;
- a door body connected to the cabinet body through a connection mechanism;
- 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, in a case that the inductor moves to a position adjacent to the first induction switch, the first induction switch generates a first control signal, which controls the driving device to stop driving so as to cause the door body to remain in an opened state;
- and in a case that the inductor moves to a position adjacent to the second induction switch, the second induction switch generates a second control signal, which controls the driving device to stop driving so as to cause the door body to reset to a closed state.
An refrigeration device, comprising:
- a cabinet body;
- a door body connected to the cabinet body through a connection mechanism;
- and
- an automatic switching system positioned on the door 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 or retract;
- 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, in a case that the inductor moves to a position adjacent to the first induction switch, the first induction switch generates a first control signal, which controls the driving device to stop driving so as to cause the door body to remain in an opened state;
- and in a case that the inductor moves to a position adjacent to the second induction switch, the second induction switch generates a second control signal, which controls the driving device to stop driving so as to cause the door body to reset to a closed state.
An automatic switching system configured to be installed on one of a cabinet body or a door body of a refrigeration device, the automatic switching system including:
- an ejection mechanism, including a gear and a rack matching the gear;
- a driving mechanism connected to drive the 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 mechanism including an inductor on the rack, a first induction switch and a second induction switch, the first induction switch and the second induction switch being communicatively connected to the driving mechanism;
- wherein, in operation, in a case that the inductor moves with the rack to a position adjacent to the first induction switch, the first induction switch generates a first control signal, which controls the driving mechanism to stop driving so as to cause the door body to remain in an opened state;
- and in a case that the inductor moves to a position adjacent to the second induction switch, the second induction switch generates a second control signal, which controls the driving mechanism to stop driving so as to cause the door body to reset to a closed state.
