Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a wall-mounted hot air heating device (including a ceiling-mounted type). The present invention relates to a wall-mounted hot air heating device that increases the heating effect by guiding the air to the room, and provides heating comfort.

[Prior art] Wall-mounted and ceiling-mounted hot air heating devices have become very popular in recent years because they do not occupy floor space. Because the structure blows out strong wind, if you feel the wind speed or move away a little, the warm air will start to feel cold, making it less comfortable.

From this point of view, an idea has been published in Japanese Utility Model Application Publication No. 181648/1983 in which a duct is used to guide warm air toward the floor.

[Problems with the Prior Art] However, in this known example, the duct from the hot air fan is extended close to the floor, which is not only unsightly, but also has only one outlet on the floor.
The disadvantage is that it is cold in the middle of the room and you can feel the wind at your feet.

The present invention is proposed in view of these points.
A feature of wall-mounted and ceiling-mounted warm air heating devices is that they allow you to feel the warmth not only on the floor side of the room, but also in the middle of the room.

[Means for Solving the Problems] As a means for achieving the above object, the present invention has a hot air generator with a hot air outlet facing downward, and also radiates air from this hot air outlet toward the floor side. Its feature is that it is equipped with a warm air guide curtain.

When a hot air guide screen is installed from the hot air outlet toward the floor in this way, the hot air will naturally descend along the surface of the hot air guide screen due to the Coanda effect, turn around at the floor, and spread into the room. .

As a result, in the room, warm air rises from the floor, that is, from the feet, and part of the warm air flows into the room in the middle of the curtain, further warming the curtain and emitting radiant heat, which warms the entire room and provides comfortable heating. At the same time, the warm air is slowed down while passing through the curtain, so there is no feeling of cold air.

[Embodiment] Fig. 1 shows an embodiment of the present invention, in which 1 is a wall-mounted hot air generator, 2 is a fan, 3 is a hot air outlet,
Reference numeral 4 denotes a hot air induction curtain that also serves as radiation and is hung from the rear of the hot air outlet 3 along the wall surface 5 to near the floor surface 6. When the hot air induction curtain 4 is hung in this way,
The hot air blown out from the hot air outlet 3 descends along the surface of the hot air guide curtain 4 due to the Coanda effect, and if it hits the floor 6 or loses its flow speed on the way, it reverses and diffuses into the room. .

FIG. 2 shows another embodiment of the hot air guide curtain 4. In this embodiment, the warm air guide curtain 4 is used to forcibly lower the hot air toward the floor surface 6, rather than using the Coanda effect. A hot air passage 4a is formed inside, and a hot air outlet 3
The warm air blown out from the floor 6 is blown into the room from the vicinity of the floor 6 via this hot air path 4a. In the case of this embodiment, a small hole passing from the hot air path 4a to the front may be provided so that a portion of the hot air flows out from the front of the hot air guide curtain 4 into the room.

4 and 5 show an embodiment in which a hot air guide curtain 4 that can be freely stored inside the hot air generator 1 is provided, with FIG. 4 showing the pulled-out state and FIG. 5 showing the rolled-up and stored state.

[Effects of the present invention] As described above, the present invention is configured to perform hot air heating by providing a hot air guiding curtain below the hot air outlet in a wall-mounted or ceiling-suspended hot air heating device. You can expect the following effects.

a. The hot air blown out from the hot air outlet descends to near the floor along the hot air guide curtain, and then some of it diffuses into the room during the process. As a result, the entire room can be warmed even though it is wall-mounted or ceiling-mounted, so comfortable heating is possible.

b. Since the system does not increase the speed of the hot air and diffuse it into the room, the hot air does not hit the body directly, so you do not feel the wind speed or feel the cold air.

c) Since the surface of the hot air guide curtain is heated, a mild radiant heating effect can also be expected.

d) A high recirculation effect can be expected because the hot air guide curtain directs the hot air downward toward the floor.

e By drawing patterns or colors on the surface of the hot air guide curtain, it can also be used as an interior decoration.

f If the hot air guide curtain is made to be freely retractable, it will not get in the way.

g. Because the hot air does not hit the wall directly, the wall will not discolor, peel, or curve due to the heat of the hot air.
