Embodiment Construction

[0036] Below in conjunction with accompanying drawing, the implementation of the present invention is described as follows:

[0037] figure 1 The description has been described in detail in "Background Technology", so it is omitted here.

[0038] In Fig. 2, the housing forms the appearance of the indoor device, which is a flattened hexahedron. The front side of the housing has a front plate capable of closing the space inside the housing.

[0039] exist image 3 Among them, the front panel body is a quadrangular shape. A quadrangular suction through-hole is formed in the center thereof. The suction through-hole portion functions to suck the air that purifies the space into the inside of the housing. Form the through-hole frame (33 ') of the support filter effect that will be explained below with " 7 type " on such suction through-hole part.

[0040] Both ends of the front panel body are provided with decorative panels facing downward from the top. The decorative plate (...

Abstract

The invention discloses a driving device for the grid of an air conditioner, which uses the driving force of a motor to open and close the grid. In particular, the suction through-hole portion of the front panel can only be opened when the air conditioner is in operation. The present invention installs a motor on the back of the front plate, and is provided with a power transmission device that transmits the driving force of the motor to the grid. The power transmission device is composed of a driving gear, a flat rack, and several driven gears inside the gear housing. The drive gear is connected to the motor to transmit the obtained power to the flat rack. There are also several driven gears that get power from the flat rack to drive each grid. At this time, the driven gear is connected to the shaft, which is connected with the hinge shaft of the grid to transmit power. As a result, the grille is automatically opened and closed by the motor, especially when the air conditioner is in operation, the suction through hole is opened, thereby preventing external dirt from entering the interior of the indoor unit.

Description

technical field [0001] The invention belongs to the class of air conditioners, and in particular relates to a driving device for an internal grid of the air conditioner. Background technique [0002] At present, the composition of the separated type air conditioner indoor unit (see figure 1 shown), its shell (1) forms the appearance of the indoor device. Shell (1) is by the cuboid of flat formula, so the length of its up and down and left and right directions is relatively bigger than the width of front and back. A front plate (2) is arranged on the front of the casing (1). [0003] Such a front plate (2) is formed with a suction through-hole portion (2') for sucking clean space air. A filter (4) for purifying air is provided in the suction through hole (2'). The filter (4) is installed in the suction through hole (2'). There is also a suction grille (5) arranged in the suction through hole portion (2'). Suction grille (5) is that the inside of front plate (2) cannot b...
