Description

[Detailed description of the invention] The present invention relates to a combustion device used in a hot-air heater, which has a simpler configuration, and the combustion device part can be easily attached and detached from the main body of the hot-air heater. With,
The purpose is to bring the combustion device into a stable state only.

The combustion device referred to herein is a general term for a burner, a combustion tube, a heat exchanger, and a combination thereof, and these parts are generally heated to high temperatures.

Therefore, it is important to prevent heat from this part from being transferred to other parts of the hot air heater, such as the control section, oil tank, etc.

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

FIG. 1 is a front view of the warm air heater, and FIG. 2 is a side cross-sectional view thereof.

Also, FIG. 3 shows the combustion device section. In the figure 1.2.3
．． 4.5.6 is a case element constituting the outside of the warm air heater, 7 is a leg, 8 is a heating blower motor, and 9 is a fan.

There is an opening 10 in a part of the front case element 6, and the air sucked in by the rear blower fan 9 travels in the direction of the arrow, becomes warm air by the heat exchanger 11, and is directed into the room through the front opening 10. It is squirted.

In the outer shell constituted by the case elements 1 to 6, a ventilation passage 16 is formed surrounded by heat shield plates 12, 13, 14 and partition plates 15.

17 is a control and operation section, and 18 is an oil tank.

As shown in FIG. 3, the combustion device section includes a burner section 19, a combustion tube 20, and a rectangular connecting body 2 for coupling these together.
1, a connecting body 22 for connecting the heat exchanger 11 and the combustion tube 20, a lid body 23 of this part, an exhaust pipe 24, and the heat exchanger 1
1 and a connecting body 25 and 26.

Further, an air supply pipe 27 is fixedly installed in the burner section 19.

The connecting body 21 has a rectangular shape with a peripheral edge, and has a plurality of protrusions 28 on the upper and lower edges.

The connecting body 22 also has a rectangular shape, but has a fixing cut-out portion 29 at its lower part. A protrusion 30 and a plurality of ventilation holes 3 are provided at the lower edge.
1 is provided.

The combustion device section having the above-described structure can be placed independently and stably on the floor as shown in FIG.

Therefore, when assembling the hot air heater, the connecting bodies 22 and 21 can be placed on the heat shield plate 14 and inserted as they are, making assembly easy.

Furthermore, since the connecting bodies 22 and 21 are placed directly on the heat shield plate 14, there is no need to use a conventional mounting bracket between them, and the structure can be simplified accordingly.

That is, each of the connecting bodies 22 and 21 can be directly attached to the heat shield plate 14.

Moreover, the problem of heat conduction to the heat shield plate 14 in this case is extremely reduced due to the presence of the ventilation holes 31 and the protrusions 28, 30, and there is no possibility that the case temperature would rise excessively due to the installation.

The heat shield plate 14 is provided with fixing fittings 32 corresponding to the fixing cut-out portions 29 of the connecting body 22, and grooves 33 are provided corresponding to the connecting bodies 21.

With the above configuration, the present invention has the following effects.

1 The combustion part is designed so that one side of the connecting body is inserted into the groove of the heat shield plate and only the other is fixed to the heat shield plate, so it can be easily attached to the heat shield plate and also easily removed. .

2 The connecting bodies of the combustion section are arranged at both ends of the combustion tube and extend downward, so they also serve as legs when the combustion section is removed.
This is convenient because the combustion section itself can be placed independently and stably on the floor, etc.

3. Since a protrusion is formed on the lower end of the connecting body of the combustion part, the contact area with the heat shield plate is reduced, and therefore the heat conduction from the combustion part to the heat shield plate is reduced, and the temperature of the outer shell is maintained low. It is now safe.

4. Since one of the connecting bodies of the combustion section is fitted into the groove provided in the heat shield plate, reliable attachment is possible even when only the other connecting body is fixed.

[Brief explanation of the drawing]
