It should be noted that prevent pressing from both sides the door plant on its moving path have with the door plant stretches out the position relatively and returns the position, wherein prevent pressing from both sides the distance that the door plant stretches out the door plant and be less than and prevent pressing from both sides the hand reservation clearance, prevent pressing from both sides the door plant and receive the effort after contacting the foreign matter, pressure sensor can feedback signal to corresponding the control unit, and the control unit makes the action and will prevent pressing from both sides the door plant and return to returning the position at once. In addition, in the opening process of the door panel, the anti-pinch door panel can be kept at the retreating position to avoid the influence of the extension of the anti-pinch door panel on the air outlet 2; during the closing process of the door panel, the door panel is firstly kept at the extending position and retreats after contacting foreign matters.
Example 2
In this embodiment, a control method applicable to the air conditioner in embodiment 1 is provided, and the control method can control the air conditioner door panel assembly 3 to achieve the anti-pinch function. The control method comprises the following steps: when the air conditioner receives a closing instruction or an air guide adjusting instruction to control the air guide assembly to close, the air conditioner controls the door panel to move from the opening limiting point to the closing limiting point; at the door plant by opening the restriction site to the direction removal in-process that closes the restriction site, whether anti-pinch device sensing air outlet 2 department has the foreign matter, stops at anti-pinch restriction site when the sensing has the foreign matter after the control door plant, or control the door plant and return to opening the restriction site. Preferably, when the anti-pinch device senses whether foreign matters exist at the air outlet 2, the anti-pinch door plate in the anti-pinch device is controlled to keep in a state of extending out of the door plate; after the sensing has the foreign matter, the control prevents that the tong door plant among the device returns the rear side to the door plant.
Specifically, the method comprises the following steps: as shown in fig. 6 to 7, the moving path of the door panel at the outlet 2 is shown. D1, D2, D3 and D4 are preset limit points at the positions of the door panel corresponding to the air outlet 2; d5 and D6 are the limiting points of the anti-pinch door panel relative to the door panel respectively. D1 is the closing limit point of the door panel, corresponding to the minimum closing position; d2 is the position when the door panel is at the extended position after moving to the anti-pinch limit point, which is the minimum position of the hand-pinch; d3 is the anti-pinch limit point of door plant, and D4 is the limit point of opening of door plant, corresponds and opens the maximum position. D5 corresponds to the extended position, which is the maximum position of the anti-pinch device relative to the door panel; d6 corresponds to the retreat position, which is the minimum position for the anti-pinch device to close relative to the door panel. Can set up D2 to D3 and D5 to D6 apart from the same, the door plant moves to be D3 promptly, prevents that tong device opens when D5, whole door plant subassembly 3 reachs D2 and corresponds prevents tong critical point, because prevent being provided with protector and relevant inspection device on the tong device, the tong is not painful and can close when detecting the tong and prevent tong door plant to D6 position, this moment: the door panel assembly 3 is retracted to the position D3 to allow the hand to be pulled out and avoid pinching the hand.
Referring to fig. 6-7, the present embodiment further provides a debugging and operating process of the door panel assembly 3 of the air conditioner using the control method.
Debugging: when the door panel is electrified for the first time, the door panel is reset by a closing distance L1 towards the direction D1 (L1 is larger than D1D4) to ensure that the door panel is closed in place (the lengths of L1, D1 to D4 and the like can be straight line lengths or arc line lengths, and the actual length is determined according to the shape and the width of the door panel)
After resetting, adjusting and positioning according to the on-off state:
if the door is in the open state, the door will close to the direction D3 by a distance L1;
if the door is closed, the door will close by a distance L1 in the direction D1.
The working process is as follows: the door plate is closed to a position D3 at a certain speed under the drive of the motor, and before the door plate reaches the position D3, the anti-pinch door plate of the anti-pinch device is moved to a position D5 under the drive of the motor; if door plant subassembly 3 just pressed from both sides the hand this moment, and the motor stop motion that corresponds with the door plant to the door plant keeps motionless, and anti-pinch device moves to D4 direction under the drive of its motor and returns, thereby makes the user who is touched the hand can take out the hand. When the above-mentioned tong condition of production, can predetermine the air conditioner and control first drive assembly and second drive assembly cooperation after dwell time t and drive the door plant earlier and move D2, before arriving D2, prevent that the tong device has accomplished the action of moving to D6 position under the drive of its motor, make door plant and prevent that the tong device is whole playback, then the door plant is closed to D1 position under the drive of motor and is realized that the air conditioner shuts down the door plant and close.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
