JPH0626701A - Method of blowing-off conditioning air from ceiling - Google Patents

Abstract

PURPOSE:To ensure an optimum blow-off speed by causing a downward blow-off flow and a horizontal blow-off flow to collide with each other to produce a turbulent flow. CONSTITUTION:A ceiling blow-off slot 10 comprises an outer cone 1, a middle cone 2 disposed inside the outer cone 1, and an inner cone 3 disposed inside the middle cone 2. The middle cone 2 is mounted so that conditioning air flowing between the middle cone 2 and the outer cone 1 is blown off downwardly of the outer cone 1. Further, the inner cone 3 is mounted so that conditioning air flowing between the inner cone 3 and the middle cone 2 is blown off horizontally toward the middle cone 2. The downward conditioning air flowing between the middle cone 2 and the outer cone 1 collides with the horizontal conditioning air flowing between the inner cone 3 and the middle cone 2 into an extended turbulent flow to promote the reduction of the speed of blow-off air and increase the amount of the blow-off air per unit.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling blowing method for introducing conditioned air conditioned by an air conditioner into a living room.

[0002]

2. Description of the Related Art Generally, conditioned air conditioned by an air conditioner is introduced into a living room through a ceiling blowing slot. Known as the ceiling blowing slot are an anmostat type and a plaque type.

[0003]

However, the former has the advantage that the conditioned air can be diffused into the living room, but has the disadvantage that the blowing speed is too high, while the latter has a small blowing speed because it blows horizontally. In addition, there is a drawback that it is less inductive and pollutes the ceiling.

The present invention has been made to solve such conventional problems, and an object thereof is to provide a ceiling air blowing method capable of obtaining an optimum blowing speed.

[0005]

SUMMARY OF THE INVENTION The present invention comprises an outer cone,
An inner cone installed inside the outer cone and an inner cone installed inside the inner cone, wherein the inner cone is in a state in which conditioned air flowing between the outer cone and the outer cone blows downward. The ceiling cone is attached to the inner cone so that the conditioned air flowing between the inner cone and the inner cone is horizontally blown out, and the downward flow and the horizontal flow are made to collide with each other. It causes turbulence.

[0006]

In the present invention, the downward conditioned air flowing between the middle cone and the outer cone collides with the horizontally oriented conditioned air flowing between the inner cone and the middle cone to diffuse into a turbulent flow. It is possible to accelerate deceleration of blown air and increase the blown air volume per unit.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a ceiling outlet slot 10 used in one embodiment of the present invention.

This ceiling outlet slot 10 is provided with an outer cone 1
And an inner cone 2 installed inside the outer cone 1 and an inner cone 3 installed inside the inner cone 2.

The inner cone 2 is attached to the outer cone 1 so that the conditioned air flowing between them is blown downward, and the inner cone 3 is attached to the inner cone 2 between them. The flowing conditioned air is installed so as to blow out horizontally.

In this embodiment, the inner cone 3 is mounted so as to be vertically movable, and the cross-sectional area of the needle can be changed according to the size of the living room.
The cross-sectional area is set when it is installed in the living room, but it may be automatically set by conditioned air heat or the like. At this time, the heat-sensitive member 5 such as bimetal or shape memory alloy
Is used. This heat-sensitive member 5 is deformed by conditioned air heat, the mounting position of the inner cone 3 is automatically displaced in the vertical direction, and the cross-sectional area of the passage 4 formed by the inner cone 3 and the middle cone 2 can be adjusted. Is attached to the outer cone 1.

Next, the operation of this embodiment will be described.
The ceiling outlet slot 1 of the embodiment configured in this way
When the conditioned air passes through 0, the conditioned air is divided into one that flows between the outer cone 1 and the middle cone 2 and one that flows between the middle cone 2 and the inner cone 3.

During cooling in which the conditioned air heat is low, the heat sensitive member 5 bends and moves the inner cone 3 upward as shown in FIG. 1, depending on the temperature, and the passage between the middle cone 2 and the inner cone 3 is moved. Make 4 wide. Then, the former conditioned air a blows downward into the living room, and the latter conditioned air a ′ blows horizontally. Therefore, the conditioned air a, a ′ collides with each other in the living room as shown in the figure, consumes kinetic energy, and diffuses as a turbulent flow. Therefore, the deceleration of the blown air can be accelerated, and the blown air volume per unit area can be increased.

On the other hand, at the time of heating in which the conditioned air heat is high, the heat-sensitive member 5 moves horizontally by moving the inner cone 3 downward as shown in FIG.
The passage 4 between the inner cone 3 and the inner cone 3 is narrowed. Therefore, the conditioned air a ′ flowing between the middle cone 2 and the inner cone 3 is made to flow downward. Therefore, it does not collide with the downward conditioned air a passing through between the outer cone 1 and the middle cone 2.

In summary, in this embodiment, the outer cone 1
And the inner cone 2 installed inside the outer cone 1,
With the inner cone 3 installed inside the inner cone 2,
The inner cone 2 is attached to the outer cone 1 so that the conditioned air flowing between them blows downward, and the inner cone 3 blows the conditioned air flowing between them to the inner cone 2 horizontally. When the conditioned air is blown into the living room, it blows downward because the downward blowing flow and the horizontal blowing flow collide with each other to generate a turbulent flow by using the ceiling blowing slot 10 attached in a state. There is an advantage that a turbulent flow is generated due to the collision of the air blown with the horizontally blown air, the deceleration is accelerated thereby, and a large blown air amount per unit area can be secured.

In the above embodiment, the case where the heat sensitive member 5 such as a plate-shaped bimetal or shape memory alloy is used has been described, but the heat sensitive member 5 such as a coiled bimetal or shape memory alloy is used for the inner cone 3. It may be attached to the upper part.

[0016]

As described above, the present invention includes an outer cone, a middle cone installed inside the outer cone, and an inner cone installed inside the middle cone, and the middle cone is an outer cone. Ceiling where the conditioned air flowing between the cones is blown downward, and the inner cone is attached so that the conditioned air flowing between the cones is blown horizontally to the middle cone. Using the blowout slot,
Since turbulence is generated by colliding the downward and horizontal blowout flows, when conditioned air blows out into the living room, the downward and horizontal blowouts collide with each other to create turbulence. This has the advantages that the deceleration is accelerated and the amount of blown air per unit area is large.
