Problems solved by technology
The existing anti-pinch devices all use optical sensors to detect the motion state of the moving gear to determine whether it is in a hand-clamping state, and often when the sensor signal is transmitted to the controller, the air outlet panel may already be in a complete hand-clamping state ( That is, the air outlet panel has moved to the limit point), which poses a safety hazard and requires technical improvement
In particular, if the sensor signal is wrong during transmission, or the sensor is insensitive due to the end of its service life, it is often easy to sense wrongly or not sense at this time, and the danger at this time is greatly increased.

The invention relates to an anti-pinch device of an opening and closing structure and air conditioning equipment with the anti-pinch device. According to the main technical scheme, the opening and closing structure comprises a first component and a second component, and the first component and the second component relatively move to open or close the opening and closing structure; the anti-pinch device comprises a retreating element, a switch and a controller, the retreating element and the switch are mounted on the same one of the first component and the second component, and the retreating element is opposite to the other of the first component and the second component and is arranged to do retreating motion towards the switch when locally pressed; the controller is used for controlling the opening and closing structure to move after receiving a trigger signal of the switch, so that the opening and closing structure stops closing motion or does opening motion. The anti-pinch device is high in reliability and accuracy and low in cost.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an open-close structure anti-pinch device and an air conditioner equipped with the same. Background technique [0002] Taking the cylindrical air-conditioning cabinet as an example, the structure of the air outlet panel needs to be equipped with an anti-pinch device to prevent the air outlet panel from being caught or even pinched, such as the user's hand, during the closing process. The existing anti-pinch devices all use optical sensors to detect the motion state of the moving gear to determine whether it is in a hand-clamping state, and often when the sensor signal is transmitted to the controller, the air outlet panel may already be in a complete hand-clamping state ( That is, the air outlet panel has moved to the limit point), which has potential safety hazards and requires technical improvement. In particular, if the sensor signal is wrong during transmission, or ...
