Description

[Detailed description of the invention] The present invention relates to a hot air heating device.

In recent years, the so-called intake/exhaust type has been introduced, which supplies combustion air from outside and exhausts it outside, supplies hot air indoors using a hot air circulation fan, and exhausts fuel such as gas or oil from the combustion chamber via a heat exchanger. Although the number of hot air heating devices is rapidly increasing, these types of hot air heating devices have a large number of parts, including electrical parts, and are complex in structure, making it difficult to repair or replace parts such as combustion chambers.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to facilitate the repair and replacement of each component by making it easy to disassemble the device.

The present invention will be explained below with reference to the drawings. Hot air heating device main body 1

The combustion section 6 includes a flame viewing window 28, a combustion chamber 30 equipped with an ignition spark and a flame monitoring device 29, and a vaporization burner section 36 connected to the combustion chamber 30 and having a combustion motor chamber 38.
It is becoming more and more.

The burner section 36 communicates with the leveler 10 and includes an oil supply pipe 32 and an overflow pipe 33 in which an electromagnetic pump 31 is installed.
Fuel is supplied from a solenoid valve 35 via an oil amount control device 34 communicating with the combustion motor chamber 38, and a combustion motor chamber 38 communicates with a feed cylinder 37 to supply combustion air to a burner section 36.

Further, the combustion chamber 30 is connected to the exhaust manifold 3 via a heat exchanger 7.
9 and is guided to the exhaust pipe 10.

The electromagnetic pump 31 is connected to the oil supply pipe 32 through a joint 41 having a substantially hexagonal cross section, and a hexagonal insertion hole 4 with a slightly larger cross section formed in the heat shield plate 27 is formed by the joint 41.
2, prevent the rotation of the electromagnetic pump 31, and then tighten the screw 43.
．． At 43, the locking metal fitting 44 and the heat shield plate 27 are fixedly attached.

Further, on the front surface of the combustion section 6 and the heat exchanger 7, a heat insulating plate 46 equipped with a temperature fuse 45, etc. is detachably fixed to the frame material 5, and between the partition plate 23 and the side wall of the frame 4. A metal fitting 48 equipped with an operation switch 47 and the like is attached to the holder.

The door 2 has an opening 49 at the top and a peephole 50 for the vibration sensing device 20 at the bottom.
a louver installation plate 53 having a hot air outlet 51 fixed to the front side wall of the louver and a peephole 52 for the operation switch 47;
The folding piece 5 provided at the upper end of the door 2
4 and a U-shaped receiver integrally formed on the front surface of the upper wall of the frame 4 can be detachably engaged with the edge 55, and the lower part of the door 2 and both side walls of the frame 4 are fixed with screws or the like. .

The electromagnetic valve 35 has an inlet 56 connected to the fuel supply pipe 32 and an outlet 5 connected to the supply pipe for supplying fuel to the burner section 36.
An operating section 63 having a coil 62 and the like for pulling up the plunger 61 against the return force of a spring 60 is connected to the base body 59 which communicates with the plunger 61 and the spring 7 through a communication hole 58. Guide tube 6 with 60 installed inside
A core 66 provided with an O-ring 65 is disposed in the upper part of the flow hole 58, and an orifice 68 having a thickness of about 1 mm and having a through hole 67 about 1 mm thick is disposed at the bottom of the inflow hole 56 of the communication hole 58. A resilient valve body 71 having a hole 69 with a larger diameter than the through hole 67 and a protruding edge 70 on the upper part is further provided in the upper part of the valve body 71 excluding the protruding edge 70. A retaining ring 72 is provided so that when the plunger 61 is lowered, the lower end of the plunger 61 and the protruding edge 70 come into contact with each other to cut off the flow of fuel.

The combustion section 6, heat exchanger 7, collection tube 39, etc. are integrally molded, and fittings 73 are installed in the combustion section 6 and the like at appropriate locations.
74 and the receiver are attached to the stand 22, and the partition plates 23 and 1 are attached with screws or the like.

The partition plate 23 is provided with a cutout 23 toward the front opening of the frame 4, and the combustion motor chamber 3 is provided in the cutout 23'.

5, 26, heat insulating plates 16 and 1 The mounting plate 17 inserted into the rail 18.18 can be removed.

Further, by removing one fitting 73 from the support 22 and the other fitting 74 from the partition plate 23, the combustion section 6, heat exchanger 7, and collecting pipe 39 can be removed as one unit.

Further, in the present invention, the electrical equipment control box 25 is housed in a chamber separated from the combustion chamber and the heat exchanger by the partition plate 23. Therefore, the heat of the combustion chamber 30 and the heat exchanger 7 is cut off by the partition plate 23, and the electrical equipment is separated from the combustion chamber and the heat exchanger. Heating of the control box 25 is suppressed.

Moreover, the partition plate has a notch facing toward the frame opening, and the combustion motor chamber of the burner unit connected to the combustion chamber is removably fitted into the notch, so that heat from the combustion chamber etc. can pass through the partition plate. There is no heat transmitted to the frame through the heat source, which heats the frame, or heat dissipated from the partition plate, which heats the control box.

That is, since the motor chamber, which does not heat up, is fitted into the notch of the partition plate, there is no heat influence from the combustion chamber or the like.

The above configuration has the advantage that the heat-sintering section, the heat exchanger, and the collecting tube can be assembled and removed within the frame extremely easily.
