Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of an air conditioning outlet.

[Prior Art] Conventionally, a blow-off unit 6 has been provided which can control the air volume from the blow-off port 4 while sensing the indoor temperature and automatically moving the damper 7 according to the situation. As shown in Figs. 6 and 7, the blow-off unit 6 is composed of an inner cylinder 2 and an outer cylinder 1, and detects the indoor temperature and automatically operates a damper 7 according to the situation. A control section 9 containing a built-in control device 8 that can control the amount of air from the air outlet 4 while moving was provided in the outer cylinder 1, and the duct 5 was directly connected to the control section 9.

[Problem to be solved by the invention] However, in the conventional example as described above, since the control section 9 is provided so as to protrude from the outer surface of the outer cylinder 1, parts of the control section 9 must be replaced. In such a case, after removing the duct 5, lower the blow-off unit 6 itself from the ceiling, remove the control section 9, and remove the control section 9.
There was a problem that maintenance of the control section 9 could not be performed easily.

The present invention attempts to solve the above problems, and its purpose is to create an air conditioning outlet structure that allows easy installation and removal of the control unit and easy maintenance. It is on offer.

[Means for Solving the Problems] In order to achieve the above object, the structure of the air conditioning outlet in the present invention is formed by an outer cylinder 1 and an inner cylinder 2, and is formed between the inner cylinder 2 and the outer cylinder 1. In a blowout unit 6, a blowout port 4 is formed in the lower part of the space 3, and a duct 5 is connected to the outer cylinder 1 so as to communicate with the space 3. A control unit 9 is removably attached to the inner wall 2a, and has a built-in control device 8 that can detect the indoor temperature and control the air volume from the air outlet 4 while automatically moving the damper 7 according to the situation. It is something.

[Function] When attaching or removing the control section 9 from the blow-off unit 6 during maintenance of the control section 9,
Only the control section 9 can be easily removed without removing the duct 5 or the blow-off unit.

[Embodiment] FIG. 1 shows an embodiment of the present invention.
The blow-off unit 6 installed on the ceiling has a double structure with an outer cylinder 1 and an inner cylinder 2 formed in a cylindrical shape, and the lower part of the space 3 formed between the outer cylinder 1 and the inner cylinder 2. A blower outlet 4 is formed in the hole. A duct 5 is connected to the outer surface of the outer cylinder 1 so as to communicate with the space 3, and the inner wall 2a of the inner cylinder 2 corresponds to the position of the duct 5. A control unit 9 is installed which incorporates a control device 8 that can adjust the amount of air from the air outlet 4 while automatically moving the damper 7 according to the situation. This control section 9 is formed by installing a control device 8 such as a drive section 8a such as a motor and a power supply section 8b as shown in FIG. 3 in a box-shaped control box 9a. It is detachably attached to the inner wall 2a of 2. In other words, there is an inner cylinder 2 at the top of the control box 9a.
A locking piece 9b is provided for locking to a locking protrusion 10 protrudingly provided on the inner wall 2a of the holder, and a thumbscrew 11 provided at the bottom is provided to lock the locking piece 9b to the locking protrusion 10. It is attached by screwing into the inner wall 2, and can be easily removed by loosening the thumbscrew 11. As shown in FIG. 2, a damper 7 is disposed in the space 3 so as to be movable (in the left-right direction in FIG. 8a via a joint 13. This joint 1
3 is formed with a plurality of fitting grooves 13a that open toward the side, as shown in FIG. A drive transmission pin 12a provided at one end of the damper shaft 12 is fitted to the damper shaft 12, so that the damper shaft 12 is rotatably connected. A threaded groove 12b is threaded on the outer surface of the damper shaft 12, and the damper 7 is fixed to the damper shaft 12 via a threaded member 14 such as a nut, and as the damper shaft 12 rotates, It is designed to move. 15 is a stopper for preventing the damper 7 from rotating.

Therefore, as shown in FIG.
Detects the indoor temperature and drives the drive unit 8a such as a motor.
By operating the damper shaft 1 connected to the joint 13 provided in the drive section 8a.
2 to move the damper 7 and space 3
The flow rate of air from the duct 5 flowing through the air outlet 4 is adjusted to adjust the air volume from the outlet 4, and air adjustment is automatically performed.

When the blow-off unit 6 is used as a general blow-off outlet when repairing the control section 9, etc., an adapter 16 made of hard rubber or the like is attached to the tip of the damper shaft 12 as shown in FIG. The damper 7 can be opened and closed manually.

[Effects of the invention] As described above, this invention detects the indoor temperature on the inner wall of the inner cylinder so as to correspond to the position of the duct, and controls the air volume from the outlet while automatically moving the damper according to the situation. Since the control section with a built-in control device is detachably attached, it is not necessary to attach only the control section to the blow-off unit.
It is removable, so when installing or removing the control part during maintenance, you can remove only the control part from the blow-off unit without removing the duct or the blow-off unit itself as in the conventional case. This allows maintenance of the control unit to be easily performed without taking much time.
