Embodiment 2

[0038] Example 2, such as figure 2 , in some embodiments, the front end 1b of the cabinet 1 is also provided with a second air return port 42, the front end of the cabinet 1 is opposite to the front side of the suspended ceiling 8, and the second air return port 42 can be connected to the The first air port 81 communicates to suck air from the second return air port 42 into the casing 1 , and there is a preset distance between the heat exchanger 3 and the top of the casing 1 . The present invention can also effectively increase the return air area, increase the return air volume, and improve the heat exchange efficiency through the structure that the front end of the casing is provided with a return air port. In Embodiment 2 of the present invention, there is a preset interval between the upper end of the heat exchanger and the casing, so that the airflow entering the second air return port can pass through the interval to reach the heat exchanger for heat exchange, increasin...

Embodiment 1

[0039] Example 1, in some implementations, the heat exchanger 3 is connected to the upper end of the casing 1 , so that the front end of the casing 1 is not provided with the second return air outlet 42 . This is the preferred structural form of Embodiment 1 of the present invention, that is, the upper end of the heat exchanger is connected to the casing, and the air cannot be effectively returned to the heat exchanger from the front end of the casing at this time. The first air outlet enters the interior of the ceiling and only reaches the first air return outlet at the top and the third air return outlet at the rear end for return air.

[0040] In some embodiments, the rear end 1c of the cabinet 1 is also provided with a third air return port 43, the rear end of the cabinet 1 is opposite to the front side of the suspended ceiling 8, and the rear end of the cabinet 1 The end is opposite to the wall, and the third air return port 43 can also communicate with the first air port...

Embodiment 3

[0064] Example 3, such as Figure 8, in some embodiments, the distributed air supply device further includes a volute 10, a gap 15 is formed at the front end of the casing 1 opposite to the first air port 81, and the gap 15 extends to the The set position of the upper end of the volute 10, the set position is close to the heat exchanger 3 relative to the front side of the casing 1, so that part of the volute 10 is exposed outside, so that the casing A second air return port 42 is formed between the upper end of the volute 1 and the volute 10, and the second air return port 42 can communicate with the first air port 81 for return air. In Embodiment 3 of the present invention, by processing the front end of the casing in the form of a notch, the entire notch can be effectively used for return air, which can increase the return air area and increase the return air volume.

[0065] The present invention also provides an air conditioner, which includes the distributed air supply d...

Abstract

The invention provides a distributed air supply device and an air conditioner, the distributed air supply device comprises an air pipe machine and a suspended ceiling, the air pipe machine is arranged in the suspended ceiling, a first air opening is formed in the front side of the suspended ceiling, and the front side is opposite to a wall and is connected with the ceiling; the duct type air conditioner comprises a machine shell, a draught fan, a heat exchanger and a first air return opening, the first air return opening is formed in the top of the machine shell, and the first air return opening can communicate with a first air opening so that air can be sucked from the first air opening; and air flow is driven by the fan to enter the machine shell through the first air opening and the first air return opening in sequence and is subjected to heat exchange through the heat exchanger. According to the invention, the problem of inconvenience in maintenance of mounting and dismounting below the suspended ceiling is solved, so that maintenance is carried out on the front side of the suspended ceiling, a unit does not need to be provided with a lower maintenance port, front maintenance is realized, and the suspended ceiling is more convenient and more attractive in appearance.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a distributed air supply device and an air conditioner. Background technique [0002] In recent years, the domestic central air conditioner has the advantages of beautiful installation and small footprint because the internal unit is installed on the ceiling (also known as the air duct unit), and its market share has been increasing continuously. At present, the mainstream air duct machine only has one air outlet, which cannot realize horizontal air supply for cooling and downward air supply for heating, and the user comfort experience is poor. For example, CN 104697044B proposes a scheme of two air outlets, but the width of the unit needs to be increased, and the engineering installation is complicated, so the scheme has low cost performance. In addition, most of the existing mainstream air duct structures have air outlet and return air on two sides perpendicular to ea...
