Description

[Detailed description of the invention] The present invention relates to the improvement of gas or oil-fired hot air heaters, and includes various methods for generating hot air in a combined body consisting of a pair of supporting plates and a connecting plate that are connected so as to be self-supporting. The hot air generating unit is constructed by assembling the components, and this unit is housed in an exterior casing, with the aim of facilitating assembly and improving maintenance.

Conventionally, the various components that make up the hot air generation unit, such as the combustion tube, burner section, and blower, have been appropriately assembled inside the exterior casing of the heater, making assembly work in a narrow space complicated, and also in the back. Maintenance, inspection, replacement, and repair of the built-in components were troublesome.

The present invention has been developed in view of this point, and the invention shown in the drawings will be explained below. Reference numeral 1 denotes an exterior casing having a front panel 2 at its front opening, in which a storage chamber 3 for a fuel supply section is formed in the right side when viewed from the front, and a storage chamber 4 for a hot air generation unit is formed in the left side. Reference numeral 5 denotes a fuel supply section, which is comprised of an oil receiver 6, a fuel tank 7 that is removably placed on the oil receiver and supplies the oil to the oil receiver, and an electromagnetic pump 8 that is attached to the oil receiver 6 to pump up fuel. 9 is a warm air outlet provided on the front panel 2, and 10 is an intake port provided on the rear panel 1' of the exterior casing.The air sucked in from the intake port 10 by a blower, which will be described later, is exchanged with the combustion tube and released as warm air. It is designed to be discharged from an outlet 9. 11 is a hot air generation unit and the third
It is assembled as shown in Figure 5 from the figure, and then the exterior casing 1
It is inserted inside and fixed. The hot air generating unit 11 will be described in detail below. 12 is both storage chambers 3,
A collar piece is formed around almost the entire circumference of one of the support plates that serves as a partition wall that divides the four rooms. Reference numeral 13 denotes the other support plate disposed opposite to the lower half of the support plate 12 with a gap therebetween, and has the function of a heat shield plate for preventing heating of one side plate of the exterior casing 1. And both support plates 12,1
The lower end of 3 serves as a supporting leg surface that allows it to be placed on a mounting surface so that it can stand on its own. 14 is one support plate 1
This plate is installed and fixed between the center part of the support plate 2 and the upper end of the other support plate 13, and is provided with an air outlet 15 toward the rear. 16 is the pair of support plates 12 and 13;
A horizontal combustion tube 18 is located between the two and is suspended from the connecting plate 14 by a hanging bracket 17, and 18 is a burner portion with a burner head 18' looking into the combustion tube 16, which is fixed to one support plate 12. and are connected to the combustion cylinder 16 by screws 19. The burner part 1
8 is a gasification combustion system equipped with a rotary atomizer rotated by a burner motor 20 attached to the outer surface of one support plate 12, and has a supply pipe 22 with a joint 21 extending from one end. 23 is connecting plate 1
The blower applies an accelerated flow to the combustion tube 16 through the air outlet 15 provided in the 4, and includes a motor 23a fixed on the connecting plate 14 via a support fitting 24 and a fan attached to one rotating shaft 23b of the motor. 23c
and a fan case 23d that covers the fan 23c and communicates with the air outlet 15. 25 is an intake fan that sends combustion air to the burner section 18;
It is attached to the other rotating shaft of the blower motor 23a and is located outside of one of the support plates 12.
26 covers the intake fan 25, and one support plate 12
A flange piece 26' on the outer periphery of the intake cover which forms an intake passage is fixed to the outer surface of one support plate 12 with screws 27. 28, 28 are a pair of support plates 12, 13
The protrusions are curved in a crescent shape at the lower portions of the support plates and are opposed to each other, and press the support plates themselves so that they protrude inwardly from each other. Reference numeral 29 denotes a guide plate for bringing the air blown from the blower fan 23c into contact with the combustion tube 16 to exchange heat and discharge it from the discharge port 9 of the exterior housing 1. It consists of a band-shaped plate having the same width, and the rear end claw piece 2
9a is screwed to the connecting plate 14, and the inner surfaces of both side edges thereof are curved so as to contact the lower part of the pair of protrusions 28, 28 while leaving a gap in the center part from the combustion tube 16, and the front end mounting ears 29b are supported by a pair. Fix the screws 30 to the front ends of the plates 12 and 13. Therefore, the guide plate 29 is curved along the pair of protrusions 28, 28, and is easily mounted so that the air can be smoothly guided.

Hot air generation unit 1 assembled as above
1 is stored in the exterior casing 1 from the front, and screws 31
The rear ends of the pair of support plates 12 and 13 are fixed to the back plate 1a of the exterior case 1, and the front end of the left board 13 is fixed to the periphery of the front opening of the exterior case with screws 32. Then, it is connected by a joint 21 to an electromagnetic pump 8 which has been assembled in advance in the storage chamber 3 of the fuel supply section of the exterior casing 1, and finally the front panel 2 is attached to form a hot air heater.

As described above, the present invention constitutes a self-supporting assembly consisting of a pair of upright support plates facing each other with a gap and a connecting plate connecting the pair of support plates, and this assembly includes a combustion tube and a blower. , the burner part, the blower guide plate, and the components for generating isothermal air are organically assembled, so assembly is easy, and the load of the parts is not applied strongly to the exterior casing. do not have. With the conventional method of directly fixing components to the exterior casing, a strong load is applied to the fixed part, but with this proposal, the bottom plate of the exterior casing is particularly strong because it can be stored inside the exterior casing using a pair of support plates that can stand on its own. If it is made strong, the outer casing will not be deformed even if it is dropped. Furthermore, one support plate also serves as a partition wall that divides the inside of the exterior casing into two storage chambers, and can also be used as a part of the intake path together with the intake cover.With the number of parts omitted, a compact hot air generation unit is constructed. can. Furthermore, since the entire unit can be taken out from the exterior casing by simply removing a few mounting members (screws), maintenance inspection is easy and maintenance is improved.
