Abstract

PURPOSE:To reduce air resistance due to a heat exchanging unit and prevent the temperature rise of a heat source in a warm-air heating machine by a method wherein the heat exchanging unit is not provided along the whole surface of the warm-air blow-off port of the warm-air heating machine but the machine is constituted so that a part of the warm-air thereof is passed through the heat exchanging unit. CONSTITUTION:The titled heater is constituted so that hot-water is circulated between a heat exchanging unit 2 and a radiator 4 through a pump unit 3 to heat the inside of a room or the like through the radiator 4. In this case, the heat exchanging unit 2 is not arranged so that it covers the whole surface of a warm-air blow-off port 1a but is arranged at the central part thereof and both sides of the warm-air blow-off port 1a is being opened, therefore, the resistance of air, blown off to the outside of the heater, is reduced compared with the heater provided with the heat exchanging unit 2 so as to close the whole surface of the unit 2, therefore, the temperature rise of a heat source in a warm-air heating machine 1 may be restricted.

Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a heater, specifically a device that heats a room by blowing hot air to the outside (forced air exhaust (FF) type gas, oil hot air heater, electric hot air heater) , oil fan heater, air conditioner, etc.) or a kerosene stove is a type of heater that directly heats floors, walls, and ceilings using a device that blows out isothermal air. The basic concept of attaching a heat exchange unit to an air outlet, collecting heat from hot air, and distributing the heat by transferring the heat exchanged heat medium to a heat radiating member installed on the floor, wall, or ceiling is already known.

That is, FIGS. 6(a) and 6(b) show conventional examples of this type. Conventionally, the heat exchange unit 2 was installed over the entire surface of the hot air outlet provided in the hot air fan 1'. If the heat exchange unit 2 is installed in this way, the air volume will decrease due to the air resistance of the heat exchange unit 2', and the temperature of the heat source (combustion chamber for petroleum equipment, heater part for electric heaters) will rise, which is dangerous. There was a drawback.

As a countermeasure for this, the fin pitch of the hot air outlet 2d can be made rougher as shown in Fig. 7 in order to reduce the air resistance of the heat exchange unit i, but if you want to have the same heat exchange area, However, there is a drawback that the size of the heat exchange unit 2' is large and the cost is high.

(Objective of the Invention) The present invention has been proposed in view of the above points, and its object is to provide a safe heater that reduces air resistance due to the heat exchange unit and suppresses the temperature rise of the heat source. There is a particular thing.

(Disclosure of invention) The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a first embodiment of the present invention, and 1 in the figure shows F.
A hot air machine like an F-type stove, Ill is its hot air outlet,
2 is a heat exchange unit provided outside the front of the hot air outlet; 3 is a pump unit connected to the heat exchange unit 2;
4 is a panel-shaped radiator connected to the pump unit 3.

Figure 2 shows the principle of operation. The hot air fan 1 takes in outside air from its air supply port 1b, burns it together with fuel in the combustion part IC, and the combustion gas exits through the exhaust port 1d. be discharged. During this time, heating is performed by exchanging heat with the indoor air in the heat exchanger 1e, and the indoor air is taken into the hot air fan 1 by the convection fan 1f, and then heated through the heat exchanger 1e.
Then, heat is transferred from the combustion part IC to a high temperature, and the hot air is discharged into the room through the hot air outlet 1 and the inside. However,
By installing a heat exchange unit 2 at this hot air outlet 1a, heat from the hot air is generated to heat a heat medium such as hot water.
This heated hot water is used to perform heating. That is, hot water is passed through the pump unit 3 to the heat exchange unit 2.
The heat radiator 4 circulates between the heat radiator 4 and the heat radiator 4, and is configured to heat the room etc. via the radiator 4.

In this case, as shown in FIG. 1, the heat exchange unit 2 is not provided over the entire surface of the hot air outlet 1&, but is provided approximately at the center thereof, and both sides of the hot air outlet 1a are open, so that the heat exchange unit 2 is Compared to the case where the heat exchange unit 2 is provided in such a way as to block the heat exchange unit 2, there is less air resistance blowing out to the outside, so the temperature rise of the heat source inside the hot air fan 1 can be suppressed.

Fig. 3 shows the internal structure of the heat exchange unit 2, in which there are two box-shaped cases with an opening 2a formed on the rear surface, and rectangular plate-shaped fin-type heat exchange members 2b spaced apart and facing each other. A large number of heat exchange members 2b are provided with a /4' eve 2c which circulates hot water through the heat exchange members 2b. In addition,
2d is a front opening.

FIG. 4 shows a second embodiment of the present invention, and this embodiment is characterized in that the heat exchange unit 2 provided at 1 m of the hot air outlet is deviated to the right or left. .

In addition, FIGS. 5(a) and 5(b) show a third embodiment of the present invention. In this example, in the first embodiment, the heat exchange unit 2
The case is characterized in that an opening 2e is formed in the upper part of the two people, and that opening 2e also functions as a hot air outlet. That is, as shown in Figure (b), hot air from the hot air fan 1 passes through the heat exchange unit 2 and is blown out as hot air from the front opening 2d as shown by the arrow, but some of it is blown out from the upper part. The air is also blown out from the opening 2e.

Note that in each of the above embodiments, the heat medium is not limited to hot water.

(Effects of the Invention) As described above, according to the present invention, a part of the hot air passes through the hot air outlet of the hot air fan without providing a heat exchange unit over the entire surface of the hot air outlet. This has the effect of suppressing the temperature rise of the heat source inside the hot air fan and realizing a safe heater.
