Abstract

PURPOSE:To relax a discomfort as otherwise experienced in cooling or heating a spot of room temperature, by constituting the titled device such that a simplified air intake device is provided at the outlet of cold/hot air for stirring a room air into a vortex by utilizing the flow velocity of outlet cold/hot air. CONSTITUTION:While an air intake plate 9 is provided around the periphery of cold/hot air outlet 6 for guiding to draw a room air by utilizing a static pressure difference between an outlet cold/hot air and the room air 3, an air vent 11 defined in the air intake plate 9 has guide plates 12, 13 inclinably attached around the periphery thereof, the guide plates 12, 13 being adapted to adjust the outlet directions of outlet cold/hot air. When these guide plates 12, 13 are pointed in the direction parallel to a current plate 2 and a cold air 3 is injected therefrom, a uncooled room air 3a is drawn through a clearance 8 due to a static pressure difference between the cold air 3 and the room air, and subsequently injected in mixture with the cold air 3. This mixture causes the cold air 3 to raise its temperature partially, whereas the drawing of room air mentioned above entails the fluctuation of room air around the outlet air, whereby facilitating more diffusion of outlet cold air 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air discharge device for a blower type air conditioner/heater used in homes, offices, etc.

As shown in Fig. 1, conventional blower-type air conditioners blow hot and cold air 6 strongly from the air discharge port 1 toward the rectifying plate 2, so that the interior of the room is locally strongly cooled or heated. It is well known that they can cause discomfort to residents and may even be harmful to their health. The above cold and warm air 6 is a vortex 4
However, the amount is small, and most of the air in the cooling/heating air filter is air that has passed through the cooler or warmer, and since this is blown strongly in one direction, it is possible to cool indoor air that deviates from the blown direction. There will be a delay in heating V. Therefore, it takes time for the entire room to reach the appropriate temperature, and continuing to use strong cooling during that time results in wasted power. To avoid such problems,
If you adjust the cooler or warmer weakly, not only will you not be able to quickly bring the entire room to the right temperature, but you will also have the disadvantage of not using the air conditioner to its full potential.

SUMMARY OF THE INVENTION An object of the present invention is to provide an air discharge device for a blower-type air-conditioning/heating machine that improves the above-mentioned conventional problems by providing a simple intake device at a cooling/heating air discharge port to draw in room air according to the flow velocity of the discharged air. be.

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

In the embodiments shown in FIGS. 2 and 3, on the front surface of the air-discharge device of the blower-type air conditioner or the air duct 5 that opens into the ceiling or wall surface, the outer surface of the air conditioner or the ceiling or wall surface 7 around the discharge port B is Then, opposing annular suction plates 9 with an appropriate ventilation gap 8 are bolted together via a spacer 10.
Around the ventilation port 11 provided on the suction plate 9 facing the entire surface of the discharge port B, there are vertical guide plates 12, left and right guide plates 1, and a full hinge 14.
It can be tilted up and down and left and right, respectively. Each guide plate 12,13 is held in substantially the same direction as the current plate 2 by the frictional force of the hinge 14. Suction plate 9 and guide plate i2. i
s is made of a metal plate or synthetic resin, but the latter is better in terms of noise, and reinforcing ribs 15 are provided as necessary.

The operation of the present invention will be explained with reference to FIG. Guide plate 12.
13 i When cold air 3 is discharged in the same direction as the current plate 2 as shown by the solid line, uncooled indoor air 6a flows from the gap 8 as shown by the broken line due to the static pressure difference between the discharged cold air 6 and the indoor air. The cold air 6 is inhaled and mixed with the cold air 6 before being discharged.

Due to this mixing, the temperature of the cold air 6 partially increases, and
The indoor air surrounding the discharged air flows due to the suction, and the diffusion of the discharged cold air is promoted. In other words, a part of the energy of the movement of the discharged cold air 6 is used to stir the indoor air, and the cold air 6 is
Spraying speed: Decrease and at the same time speed up the averaging of indoor temperature. As a result, the discomfort caused by the conventional direct blowing of cold air is eliminated or alleviated, and by actively averaging the room temperature, it is no longer necessary to perform excessively strong cooling to completely eliminate the lack of cooling in some parts of the room. This also helps save energy.

FIG. 4 shows an embodiment in which the device of the present invention is installed inside a blower type air conditioner. At the front of the discharge port B of the duct 5 that guides the cooled and warmed air 5 that has passed through the cooler or warmer, the air conditioner outer surface 7
Discharge port 6. ! : A ventilation opening 11 with a large area of 9 is provided, and a guide plate 12.1 is installed around the ventilation opening 11 in the same manner as in FIG.
3 (13 not shown) is attached with a hinge 14, and the area around the intake port 16 provided on the outer surface 7, the discharge port 6, and the ventilation port 1.
Annular suction plates 9a and 9bk are fixed between the periphery of 1 and the periphery of 1.

The suction plates 9a and 9b completely form an annular air passage bent in a trumpet shape, and the intake port 16 is provided with an intake air amount adjusting door 17 as required.

In this embodiment as well, the outside air is sucked in from the intake port 16 by the cold/hot air 3 discharged from the discharge port B and mixed with the cold/hot air, and the same effects as described above are achieved. If the door 17 is provided, all the above-mentioned effects can be adjusted depending on the degree of opening and closing.
It is possible to selectively use local rapid heating and cooling indoors and slow immersion heating and cooling throughout the room.

Figure 5 shows an example of installation in a duct type air outlet opening in the ceiling, wall, etc.
An outer panel 7a having a guide plate 12 around the outer panel 10 and an intake port 16 provided on the outside thereof, a duct 5a used for connection with the ventilation duct 5, and guide plates 9a and 9b are fixed to form a single air outlet. The present invention has the above configuration, and has the following effects: alleviating discomfort caused by local cooling or heating indoors, promoting averaging of indoor temperature, and efficiently regulating temperature; It is also effective in saving energy.
