For fixed-installed cabinet-type air conditioners, generally speaking, due to the influence of the swing angle and mutual position of the louver grilles, the effect is good in the front of the cabinet-type air conditioner, and the effect is poor in the direction deviated from the front. Using central air conditioners or high-power air conditioners, and using network technology or remote control technology to start up in advance can make the entire space more comfortable. However, in terms of energy saving and use costs, there are problems of high energy consumption and high cost. The mobile air conditioner can solve this problem, but it has the following disadvantages: the integrated mobile air conditioner is noisy and inconvenient to drain; the split type mobile air conditioner has a complex pipeline connection structure between the internal and external units and is easily damaged.

In addition, most of the existing room air conditioners adopt an open air outlet structure, and dust easily enters the air conditioner, so that the dust directly adheres to the fins of the evaporator, which affects the performance of the air conditioner to a certain extent and reduces the The performance of the whole machine. In addition, the space between the air panels of the air outlets is generally large, and foreign matter can easily enter the interior of the air conditioner, which will affect the normal use of the air conditioner. For some air conditioners with an air outlet switch structure, for example, the opening and closing of the air outlet is realized by adjusting the swing angle of the horizontal wind board or the vertical wind board, and the gap between the wind boards makes the overall appearance of the air conditioner less than perfect; another The second is to use a combined motion mechanism to realize the opening and closing of the air outlet. This motion mechanism needs a driving device to realize it, and the structure is complicated and the cost is high.

The Chinese patent "Samsung Electronics Co., Ltd." with application number 01109856 discloses an air outlet device for an air conditioner. The device includes a damper that selectively opens and closes the exhaust port. A pair of support pins installed next to the damper are used to guide the lift of the damper. The device also includes a lifter for selectively raising and lowering the damper. The lifting device includes a pair of lifting members sliding on the support plate, a drive motor for generating power to move the lifting members, and a power transmission device for converting the rotational motion of the motor into synchronous linear motion of the lifting members.

The Chinese patent "LG Electronics Co., Ltd." with application number 00103616 discloses a switch assembly for an air outlet of an air conditioner. There is an air outlet for exhausting air; a front panel, which is combined with the cabinet body at the lower side of the upper panel; and an air outlet door, which is arranged at the front of the air outlet and is opened and closed by moving up and down The air outlet; the anti-step drop panel, the anti-step drop panel is arranged at the lower part of the air outlet, so that it can move back and forth, when the air outlet covers the air outlet, the anti-step drop panel is used to prevent the There is a step difference between the front panel and the outlet valve; a door driver is arranged on the inner side and upper panel of the outlet valve so as to move the outlet door up and down; and a panel driver is arranged on the inner side of the anti-step drop panel and the upper panel, so as to make the anti-step drop panel move back and forth.

In the air outlet device of the above-mentioned air conditioner and the switch assembly of the air outlet of the air conditioner, the opening and closing of the air outlet can realize a complete one-sided appearance, but it adopts a relatively complicated transmission mechanism to convert the rotational motion of the motor into an outlet. The rectilinear movement of the air door, through the up and down linear movement of the air outlet door to open and close the air outlet, requires high manufacturability and reliability, is prone to failure, and increases the cost.

In view of this, the present invention is proposed.
