Conventionally, there are various types of galleys used to ventilate indoor air. However, in most of these, the galley main body and register part are integrated, so it is necessary to prepare various sizes to accommodate changes in the thickness of the wall to which the galley is attached. However, it had the drawback of being extremely uneconomical from both production and sales perspectives. In addition, the noise generated outdoors has been increasing recently, but since this noise can enter the room through the galley and cause discomfort to the residents, there are strong demands from customers for soundproofing measures. The current situation is that there is no suitable solution available. Also, when the galley is attached to a wall, it is not possible to properly drain the water between the galley and the wall, and as time passes, accidents occur in which rainwater enters the interior through the gap and stains the wall. There were many things to do.

The present invention was developed to solve these problems, and has a structure in which the ventilation unit body corresponding to the galley body and the register are separated and detachable, making assembly extremely easy. It is easy to attach to walls, etc., and even if the thickness of the wall to which it is attached changes, it can be easily attached by simply changing the length of the shaft that fixes the register to the ventilation unit body. can be,
In addition, a soundproofing material is placed inside to form a soundproofing wall, which has a soundproofing function that attenuates the noise that enters the room from outside through the ventilation unit.

The knob 30 includes a knob main body 38 having an outer diameter and a hole 37 bored in the axial center so as to communicate with the through hole 31 so that the head 33 can move freely in the axial direction. Note that the pipe member 34 has a through hole 31
The shaft 35 holds the knob 30 by constantly pressing against the inner wall of the shaft 35.

A screw receiver 39 into which the shaft 35 can be screwed into the 4-axis position of the locking body of the fixed frame 10, and a shaft 35 which can be inserted through the register body 19 axis position of the support frame 23 with a diameter smaller than the outer diameter of the protrusion 32. A hole 40 is provided, and the shaft 3
5 is inserted into the hole 40, the screw 29 is screwed into the screw receiver 39, and tightened through the protrusion 32 to fix the locking body 4 and the register body 19, and to stably hold the shaft 35. let Next, after inserting the fixing part 36 into the through hole 28 of the cover 21, the nut 41 is screwed to fix the knob 30 to the bottom of the tightening recess 27, and the cover 21 is mounted so as to be movable in the axial direction. The register body 19 of the register 18, the support frame 23, the cover 21, the shaft 35,
and the knob 30 are made of the same material as the retaining shell 1. 42 is a ventilation unit.

The method of using the ventilation unit 42 will be explained below with reference to FIG. First, the shaft 35 is turned using the screw hole in the head 33 of the bolt 35 to detach it from the screw receiver 39, the ventilation unit body 2 and the register 18 are separated, and the holding shell 1 is pulled out from the ventilation unit body 2.

Next, the holding shell 1 is inserted into the ventilation hole 44 provided in the wall 43 to which the ventilation unit 42 is attached, and the holding shell 1 is inserted into the wall 43.
3 and the holding shell 1 is filled with a suitable filler 45 to fix the holding shell 1. Next, the locking body part 4
is inserted into the holding outer shell 1 from the outside to attach the ventilation unit main body 2, and then the register main body 19 is inserted into the holding outer shell 1 from the inside, and the shaft 35 is turned and screwed into the screw receiver 39 of the ventilation unit main body 2. After attaching the register 19 so as to bring the flange 26 into contact with the register outer flange 25 and shield the outside of the register main body 19, fill the gap between the wall 43 and the outer flange 13 of the flange portion 14 with appropriate filling. Ventilation unit 4 is filled with material 25.
Complete installation of step 2. When using the ventilation unit 42, grasp the knob 30 and pull it inward.
The cover 21 moves in the axial direction on the shaft 35 and is locked to the shaft 35 by the pipe member 34, the cover 21 stops, and the register outer flange 25 of the register body 19 is moved.
A gap is created between the cover 21 and the flange 26 of the cover 21, allowing air to freely enter and exit. Further, when the knob 30 is pushed in the opposite direction, the cover 21 moves and blocks the air flow path.

In this case, the ventilation unit 42 has a structure in which the ventilation unit main body 2 and the register 18 are separated and detachable.
The screw 2 of the shaft 35 is extremely easy to attach to the wall 43, etc., even if the wall 43 to which it is attached becomes thick.
It can be easily mounted by lengthening a certain portion of the shaft 9 or replacing the shaft 35 with a longer shaft. In addition, the airflow passage of the ventilation unit 42 is designed so that the air traveling straight once collides with the soundproof wall 15 of the cover 21, so that the effect of attenuating noise entering from the outside is very large. Furthermore, when the ventilation unit main body 2 is attached to the wall 43 etc. from the outside, a wide gap is formed between the wall 43 and the flange 14, so filling the filler 45 is extremely easy and prevents water from entering. It is possible to perform the closing process reliably. Furthermore, even if the diameter of the ventilation hole 44 provided in the wall 43 etc. changes considerably, the thickness of the holding outer shell 1 can be changed or the holding outer shell 1 can be removed if the ventilation hole 44 has a good finish. You can respond to this by doing something like this.

In the above embodiment, the ventilation unit body 2
Although the holding outer shell 1 is used on the outside of the register 18, if the finish of the ventilation opening 44 of the wall 43 or the like is good, the holding outer shell 1 may be directly attached without using it. Also, the collar 14 of the locking trunk 4 and the collar 17 of the hood 5
Although the hood 5 is fixed in place, the hood 5 may be removably fixed with screws or the like. In this case, there is an advantage that the insect screen 6 can be cleaned easily. Further, the shaft 35 of the shaft device 20 was fixed by tightening the fixed frame 10 and the support frame 23 using the screw receiver 39 and the protrusion 32, but instead of the screw receiver 39, it could be directly screwed into the fixed frame 10 or The nut may be fixed, or the shaft 35 itself may be thickened from that part instead of the protrusion 32, and the required ventilation unit main body 2 may be
If the shaft 35 can be firmly and stably fixed while the register 18 and the register 18 can be made detachable, the method is not limited to the above method. Also, the fixed frame 10 and the support frame 23
is the locking trunk 4 and the inner flange 8 of the register body 19.
Although both ends are fixed to the register inner flange 22 with rivets 9, welding or gluing may be used instead of the rivets 9.
Instead of providing a
It may be fixed to the peripheral walls 7 and 24 by any method such as riveting, welding, or adhesive. Also, the locking body part 4
and the register body 19 was formed into a cylindrical shape,
A rectangular tube shape may be used instead of a cylindrical shape. In this case, the shape of the hood 5 and the cover 21 is naturally selected to match this.

Since the present invention has the above configuration, it has the following effects.

(1) Since the ventilation unit body and the register are separable and removable, it is extremely easy to assemble and attach to a wall, etc., which improves work efficiency and contributes to reducing construction costs.

(2) It is versatile enough to be able to respond to changes in the thickness of the wall it is attached to and the diameter of the ventilation openings by simply replacing a few parts.

(3) Since the airflow passage is formed by receding the cover, the noise damping effect of the cover and the surrounding wall soundproofing is improved, which satisfies the demands of customers, contributing to sales expansion. .

(4) When the ventilation unit is installed, a wide gap is formed between it and the wall, etc., so water can be removed easily and reliably.
Conventional accidents can be completely prevented.
