Abstract

The invention provides a wall hanging type air conditioner indoor unit, which solves the problems of the prior art, such as limited temperature conditioning speed and capacity due to less air intake quantity arising from limited air intake area. The wall hanging type air conditioner indoor unit comprises a movable face plate, and a switching device for opening / closing the movable face plate. The switching device comprises a drive motor, a transmission mechanism, a cover component and a link rod running mechanism, wherein the link rod running mechanism is connected with the movable face plate, when the drive motor drives the transmission mechanism, the transmission mechanism drives the link rod running mechanism to open / close the movable face plate. During starting up, the motor drives gears to drive a transmission shaft, and the transmission shaft drives a four bar linkage mechanism, so as to open the movable face plate along the diagonal line of a quadrangle, thereby increasing effective air intake area, increasing air intake quantity, and improving the refrigeration / heating capacity and overall performance of an air conditioner.

Description

technical field

[0001] The invention relates to the technical field of air-conditioning and refrigeration engineering, in particular to a wall-mounted air-conditioning indoor unit in a split-type air-conditioning machine. Background technique

[0002] The panels of the existing wall-mounted household air conditioner indoor units are basically closed and fixed during the operation of the air conditioner. This structure has been used for many years and is still in use today, but there are the following deficiencies: ①. The air intake of the indoor unit can only rely on the grille holes on the top side of the outer cover, and the area of ​​the grille holes is fixed. The wind area remains unchanged, so the air intake is limited, resulting in a small amount of air intake, which in turn leads to a limitation in temperature adjustment speed and capacity, and there is little room for improvement in the overall performance of the air conditioner; ②. The structure is relatively simple...

Examples

Embodiment

[0025] see figure 1 , figure 2 and image 3 , in order to start the machine, the movable panel 1 can be switched, and a movable panel switch device is provided. Drive motor 4, gear a5-1 and gear b5-2 are all installed on the motor seat of a plastic product (not shown in the figure). The motor seat and the left cover 8-1 are fixed by hooks and screws, and the cover assembly 8 is fixed by screws on the top screw holes and the panel seat 2-1. In addition, there is also a motor shield of plastics to seal the drive motor 4, gears, etc., and the motor shield and the motor seat are fixed on the panel seat 2-1 with screws.

[0026] The transmission mechanism includes a gear set and a transmission shaft 6, the gear set includes a gear a5-1, a gear b5-2 and a synchronous gear 5-3, the driving motor 4 is connected with the gear a5-1, and the synchronous The gear 5-3 is sleeved on the transmission shaft 6, the gear a5-1 meshes with the gear b5-2, and the gear b5-2 meshes with the syn...
