Embodiment 1

[0034] A ceiling air conditioner internal unit, such as Figure 1-3 As shown, it includes a housing, a heat exchanger 6, and a wind generating device.

[0035] The casing includes a top cover 1 and a cylinder body. The cylinder body includes an inner cylinder 2 and an outer cylinder 3 arranged in sequence from the inside to the outside. 1 welding fixed.

[0036] The cylinder wall of the inner cylinder 2 is provided with an air return port 201 , so that indoor air enters between the inner cylinder 2 and the outer cylinder 3 through the air return port 201 . Multiple air return ports 201 are provided, and the plurality of return air ports 201 are evenly distributed on the cylinder wall of the inner cylinder 2, so as to improve the air intake effect of indoor air.

[0037] The lower part of the tube wall of the outer tube 3 is a curved surface structure, and the lower part of the tube wall of the outer tube 3 is provided with an air outlet 301, and there are multiple air outlet...

Embodiment 2

[0046] The second embodiment is the same as the first embodiment, the difference is that, as Figure 4 As shown, in the indoor unit of the ceiling air conditioner in the second embodiment, the outer cylinder 3 is rotatably connected with the top cover 1 through a rotating device.

[0047] The rotating device comprises a rotating motor 7, a driving wheel 8, a driven shaft 9, a driven wheel 10, and a support rod 11.

[0048]Rotating motor 7 is installed and fixed on the upper end surface of top cover 1 by fasteners, and the output shaft of rotating motor 7 passes through the rotating hole that is located on the top cover 1, and the output shaft of rotating motor 7 fits with the rotating hole clearance. The lower end of the output shaft of driving wheel 8 and rotating motor 7 is welded and fixed. The driven shaft 9 is a cylindrical structure with both upper and lower ends open. The shaftless motor 4 is arranged in the driven shaft 9. The upper end of the driven shaft 9 is welded...

Embodiment 3

[0053] The third embodiment is the same as the second embodiment, the difference is that, as Figure 5 As shown, in the ceiling air-conditioning indoor unit of the third embodiment, the air outlet 301 of the outer cylinder 3 is provided with a bar 14, and the bar 14 is connected with the outer tube 3 through an adjustment device.

[0054] The adjusting device includes an adjusting motor 15, which is fixed with the outer cylinder 3 through fasteners, and the output shaft of the adjusting motor 15 is welded and fixed to the lower end of the bar 14.

[0055] When it is necessary to reduce the air volume at the air outlet 301, start the regulating motor 15, and the output shaft of the regulating motor 15 drives the bar 14 to rotate together, so that the bar 14 covers part of the air outlet 301, thereby reducing the passing area of ​​the air. Further, the air volume at the air outlet 301 is reduced.

[0056] When it is necessary to increase the air volume at the air outlet 301, st...

Abstract

The invention discloses a ceiling air conditioner indoor unit and an air conditioner. The air conditioner indoor unit comprises a shell, a heat exchanger and an air generating device, wherein the shell comprises a top cover and a cylinder body, an upper end of the cylinder body is connected with the top cover, the cylinder body comprises an inner cylinder body and an outer cylinder body which aresequentially arranged from inside to outside, a lower end of the inner cylinder body is connected with a lower end of the outer cylinder body, an air return port is formed on a wall of the inner cylinder body, an air outlet is formed on a wall of the outer cylinder body, and the heat exchanger and the air generating device are sequentially arranged between the outer cylinder body and the inner cylinder body and connected with the shell. The air conditioner comprises the air conditioner indoor unit, and the air conditioner indoor unit is the ceiling air conditioner indoor unit. The air conditioner indoor unit is advantaged in that the indoor air subjected to heat exchange through the heat exchanger can be blown out horizontally or obliquely, and downward direct blowing is avoided; the air conditioner improves the heat exchange effect and improves the comfort level.

Description

technical field [0001] The invention relates to the technical field of ceiling air conditioners, in particular to an inner unit of a ceiling air conditioner and an air conditioner. Background technique [0002] With the rapid development of the air-conditioning industry, air-conditioning must not only meet the needs of cooling and heating, but also match the size of the indoor space. The space is more crowded, so ceiling air conditioners are becoming more and more popular, because the internal unit of the ceiling air conditioner is embedded in the indoor ceiling, which reduces the occupied indoor space. [0003] However, since the ceiling air-conditioning internal unit of the ceiling air conditioner is embedded on the indoor ceiling, the wind coming out of the air outlet of the ceiling air-conditioning internal unit blows straight down, especially in summer when the air conditioner is cooling, the wind directly blows down to the top of the user's head. , thus causing the us...
