Problems solved by technology

[0004] This common air-conditioning indoor unit has the following defects: First, the air inlet is always open. Although the air inlet is provided with a filter, the dust and particles in the air will still enter the indoor unit and be attached to the evaporator. Affect heat transfer efficiency
Second, since the panel cannot be moved during operation, it is necessary to reserve a large area of ​​air intake grille and surrounding curved surfaces, making the appearance look messy, rather than simple and generous
Compared with the traditional ordinary air-conditioning indoor unit, it makes up for the defects of the above-mentioned ordinary air-conditioning indoor unit, but it also has the following disadvantages: if the panel moves outwards too far, the moment will increase, and the support rod of the panel is relatively thin, which will cause long-term use. Easily deformed or broken, and affects the overall appearance of the air conditioner

Embodiment 1

[0028] Such as figure 2 As shown, the air conditioner indoor unit of the present invention includes a base body (4), a cover part (2) assembled on the base body, and a movable panel (3) installed on the cover part. When the air conditioner indoor unit is energized and running, the panel (3) is opened, and (1) is an air inlet, which is divided into a left air inlet, an upper air inlet, and a right air inlet, and also includes an outer cover part (2) placed on the base body (4). Motors, fans and heat exchangers inside.

[0029] image 3 and Figure 4Shown is the appearance principle diagram and partial enlarged diagram of the double bevel gear transmission mechanism of embodiment 1. A group of bevel gears are respectively arranged at the left and right ends of the panel (3) through the transmission shaft (15), the transmission shaft (15) is connected with the output shaft of the stepping motor (10), and the stepping motor (10) is installed on the outer cover The lower end o...

Embodiment 2

[0032] Compared with embodiment 1, embodiment 2 is only different in transmission mechanism. Figure 5 and Figure 6 Shown is the appearance principle diagram and partial enlarged diagram of the single bevel gear transmission mechanism of embodiment 2. A bevel gear (11L) is respectively established in the middle position of the left and right ends of the panel (3), and the bevel gear (11L) is connected with the output shaft of the stepper motor (10) respectively, and the stepper motor (10) is installed on the cover part ( 2) The left and right ends correspond to the positions. When starting up, the stepper motor (10) drives the bevel gear (11L) to rotate, and the bevel gear (11L) meshes with the bevel gear (12L) whose end is fixed on the panel (3). (12L) moves forward through the guide rail (16) to drive the panel (3) to open. By adjusting the pitch circle diameter of the bevel gear (11L), the desired panel inclination angle can be achieved.

Embodiment 3

[0035] Similarly, embodiment 3 also adopts different transmission mechanisms. Figure 7 and Figure 8 Shown are the transmission mechanism diagram and cross-sectional diagram of the double spur gear of embodiment 3. Spur gears (13S, 13M) are respectively set at the upper and lower ends of the panel through transmission shafts (15), and the spur gears (13S) and the spur gears (13M) are different in size. The driving device for the movement of the panel (3) is composed of a stepper motor (10) at the upper and lower ends, the transmission shaft (15) is connected with the output shaft of the stepper motor (10), and the stepper motor (10) is placed on the cover part The upper and lower positions of one end of (2), when the indoor unit is turned on, the stepper motor (10) drives the cylindrical gear (13S) to rotate, the cylindrical gear (13S) meshes with the cylindrical gear (14S), and one end of the cylindrical gear (14S) Fixed on the panel (3), the cylindrical gear (14S) drives ...

Abstract

An in-door air conditioning with its plate which can move to an angle comprising a base1 and enclosing component fitted with it, the plate installed on the enclosing component, the electric machine fan and heat exchanger installed in the enclosing component which is on the air conditioning, the driving motor fixed on the plate driven by it, which is connected to the powered mechanism fixed on the enclosing component. When the air conditioning works, the plate moves ahead to form an angle, the space of its upper opening is bigger than that of its lower opening, the space between the open plate and the enclosing component is air inlet when the air conditioning stops, the plate is closed and with the enclosing component. The plate's movement controls the air inlet of air conditioning to open or close, the air inlet is large and the amount of wind is large as well when it is open, the dust and particles can flow into when it is closed, and its appearance is clean and beautiful.

Description

technical field [0001] The invention relates to an air-conditioning indoor device, in particular to an air-conditioning indoor unit whose panels can move and form a certain inclination angle. Background technique [0002] Generally, an air conditioner is a device that transfers the heat in the indoor air to the outside through the continuous cycle of heat transfer, so as to achieve the desired indoor air condition. One type of air conditioner is a split wall-mounted type, consisting of an indoor unit and an outdoor unit, and the indoor unit is installed and fixed on the wall. [0003] Such as figure 1 Shown is the appearance of an ordinary split wall-mounted air conditioner indoor unit, which includes a base body (4), a heat exchanger, a motor and fan system, an outer cover part (2), a panel (3), and a display part (8). The outer cover part (2) is installed on the base body (4), the panel (3) is installed on the outer cover part (2), the air inlet is composed of the rear a...
