Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation system for ventilating a room, and in particular, a fan casing with a blower outlet facing downward, and a fan casing with a blower outlet facing downward, and a fan casing with a blower outlet facing downward, and a fan casing with a blower outlet facing downward. This invention relates to a ventilation device equipped with a flapper suitable for changing the temperature.

An object of the present invention is to eliminate the harmful effects of indoor air and to effectively utilize indoor air.

That is, the gist of the present invention is to circulate indoor air by directing the outlet of the blower downward and blowing air toward the floor surface, thereby making the indoor temperature distribution uniform;
By interposing a rotatable flapper wind direction plate in this downward airflow, the wind blowing direction can be freely selected. For example, even if a chest of drawers is placed below the indoor air outlet, , it scatters the cotton dust etc. that has accumulated on the dresser, and prevents the harmful effects of wind such as blowing air directly onto the residents and disturbing their clothes and hair, and as mentioned above, makes it possible to make effective use of indoor air. It is characterized by the fact that

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a main body case, which has partition plates 5a to 5d inside thereof, and a funnel-shaped partition plate 5a is attached between the top and bottom surfaces of the main body case 1, and an exhaust passage is formed through both lower notches of the funnel shape. 6 and an intake passage γ.

Reference numeral 2 denotes a heat exchange element disposed between the side wall of the main body case 1 and the partition plates 5a to 5c, airtightly and removably between the exhaust passage 6 and the intake passage 7, by appropriate means. , made of a moisture-impermeable member having heat conductivity such as metal, nonferrous metal, or plastic, and having a plurality of, for example, wavy heat exchange surfaces 29, through a flat plate such that the wavy heat exchange surfaces are perpendicular to each other. They are stacked on the mounting frame at predetermined intervals, and intake and exhaust air is formed to pass through the stacked layers in alternating flow directions.

4 is a capillary material (for example, a gauze-like core material) which is pasted to cover a part or the entirety of the ventilation passage of the heat exchange element 2 and elastically supported by a separate locking member 30 on the mounting frame body. ), and if necessary, a part of this wick 4 is brought into a water receptacle 3 which is removably disposed below the wick 4 by appropriate means.

On the other hand, a biaxial motor 11 is screwed and fixed to the partition plate 5d in an airtight manner between the exhaust passage 6 and the intake passage 7 by interposing an elastic member (not shown). It is.

Further, the exhaust passage 6 and the intake passage 7 are provided with a fan casing 9 disposed by appropriate means, and in particular, the indoor fan casing 9 for intake has a discharge port 41 disposed on the side wall side of the main body case 1. It is what it is.

Inside the fan casing 9, a multi-blade fan 10 is attached to the shaft of the motor 11 to constitute an air intake/exhaust blower.

Further, a front cover 20 having an opening communicating with the exhaust passage 6 is provided on the indoor side of the main body case 1 (as described later, on the left side of the wall H), and the front cover 20 and the partition plate 5c are used to exhaust air. The space between the passage 6 and the intake passage 7 is maintained airtight and removably fixed by appropriate means, and on the other hand, the outdoor side (the right side of the wall H)
The back cover 18 has an outdoor suction port 27 that communicates with the intake passage 7, and an outdoor air outlet 28 that communicates with the exhaust duct 19 mounted on the fan casing 9, which is located inside the exhaust passage 6. The space between the exhaust passage 6 and the intake passage 7 is maintained airtight and fixed by appropriate means.

A weather cover 16 having a net 17 covering the outdoor suction port 27 and the outdoor air outlet 28 is fixed to the back cover 18 by appropriate means.

In addition, an indoor air outlet 13 is provided from the lower part of the front surface of the grille 23 to the bottom surface, and the indoor air outlet 13 is connected to a fan casing 9 located in the intake passage 7 with an air intake duct 12 interposed therebetween by appropriate means. One or more drainage holes 8 are bored in the bottom surface of the main body case 1 on the outdoor side.

On the other hand, a flapper 14 made of a rotatable translucent material and having a fulcrum 15 and a wind direction plate 40 is disposed below the indoor air outlet 13, and a flapper 14 made of a rotatable semi-transparent material is provided below the indoor air outlet 13.
A grill 23 having an indoor suction port 26 is removably attached above the indoor air outlet 13 so as to cover the indoor air outlet 13, and a filter 24 having a net 25 is interposed in the indoor suction port 26. It communicates with the exhaust passage 6 through the opening of the front lid 20.

Note that H is a wall, for example, and the left side of this wall in FIG. 1 is the indoor side, and the right side is the outdoor side.

Next, the operation of the present invention having the above configuration will be explained.
Dirty air inside the room is exhausted to the outdoors through a heat exchanger as shown in Figure 1 (A), and fresh air from the outdoors is directed downward to the indoor side through the heat exchanger as shown in Figure 1 (A). It is something that is blown out.

The air intake passage is made up of a funnel-shaped partition plate and a front cover on the indoor side of the main body, but since the outlet of the fan casing is arranged near the side wall of the main body case, the fan casing blocks the intake passage. Since the space shown in FIG. 2G can be secured without having to do this, ventilation resistance has the effect of being reduced.

By setting the flapper 40 provided at the indoor air outlet 13 at an arbitrary angle, the flow of air blown into the room can be selected.

This will be explained based on FIG. 4.

(1) When the flapper 40 is set as shown in Figure A, downward blowing air can be obtained.

This strong downward wind equalizes the indoor air temperature.

That is, the air discharged from the indoor air outlet 13 is heated by the heat exchanger.

This wind temperature diffuses the cold air near the indoor floor, raising the temperature of the floor and bringing the indoor temperature closer to uniformity.

FIG. 5 shows this.

(2) By setting the flapper 40 as shown in figure A', it is possible to equalize the indoor temperature in the same way as in the case of figure A.

(3) When the flapper 40 is set as shown in figure A,
It is possible to equalize the indoor temperature in the same way as in the case shown in the figure.

Since the speed of the wind is weaker than in the case of figure A, the degree of uniformity of the indoor temperature is less. (4) When the flapper 40 is set as shown in figure B, the wind is bent in the horizontal direction.

A chest of drawers can be placed directly below the air outlet 13.

However, it cannot be expected that the indoor temperature will become uniform.

(5) When the flapper 40 is set as shown in figure C,
It is almost the same as the case shown in the figure.

In the case of figures C and B, the chest of drawers can be attached to the wall, so the indoor space can be used effectively.

(6) When the flapper 40 is set as shown in Figure D, the blown air hits the wall once and is softened, so the resistance of the occupants due to strong winds can be reduced.

As described above, in the present invention, since the indoor air outlet is provided with a flapper whose angle can be set arbitrarily, it is possible to equalize the indoor air temperature, effectively utilize the indoor space, and take into consideration the air blowing to the occupants. The practical effect that can be achieved is that of a dog.
