Description

[Detailed description of the invention] This invention relates to the improvement of hot air heaters, which conventionally heat the room by emitting warm air through the lever of the frame with a combustion mechanism inside. In this case, as shown in Fig. 1, since the outlet b for discharging hot air was formed in the entire louver a, the hot air radiating section, such as the heat exchange section or the hot air blowing section, from which the hot air was actually discharged was used. For example, mechanical parts d such as oil supply equipment, electrical components e, wiring f, etc. may be exposed to the outside from parts other than the part facing c, making them unsightly and detracting from the aesthetics, and dust etc. may be drawn into the frame from here. This could cause malfunctions or abnormal combustion.

This invention focuses on this point and attempts to provide a hot air heater that eliminates the above-mentioned drawbacks.

Next, an embodiment of this invention shown in the drawings will be described. 1 includes an inwardly pocket-shaped evaporative combustion burner 2 and a combustion fan 4 that supplies combustion air to the combustion burner 2 through a wind barrel 3. A frame housing a combustion mechanism 5 consisting of a supply device (not shown) for supplying fuel to the combustion burner 2, etc., and a front panel having a viewing window 6 for checking combustion, an oil level gauge window 7, etc. on the front. It is equipped with 8.

Reference numeral 9 denotes a louver consisting of a plurality of blades that support the upper end of the front panel 8 at its upper end, are exposed at the upper part of the front panel 8, and guide the release of hot air. A small rising wall 12 is left at the lower end of each central portion facing a hot air radiation section 11 consisting of an air path for discharging hot air generated by combustion forward by a hot air fan 10 at the rear of the frame 1. an electrical component 15 provided on the operating section 14 formed on the upper surface of the other frame 1, and the electrical component 15 and the fan motor 16.
A shielding plate 20 is provided at both side portions facing the wiring 18 connecting the control printed board 17, etc., and the oil supply device, etc., for shielding the inside of the rising frame 1, leaving a slight gap 19 smaller than the discharge port 13 above. ing.

Reference numeral 21 denotes a combustion cylinder which stands above the combustion burner 2, and has an opening 22 formed in its front surface and a plurality of small holes 23 for rectifying fuel air formed in its upper surface.

Reference numeral 24 denotes a shielding plate that covers the outer periphery of the combustion tube 21, and a see-through window 25 facing the viewing window 6 of the front panel 8 is provided on the front surface.

26 is a support stand that supports the combustion burner 2;

27 is a fixing plate for fixing the combustion fan 4, fan motor 16, and control printed board 17;

28 is an operation lid, and 29 is a lower plate.

This idea is constructed as described above,
Hot air generated by combustion in the combustion mechanism 5 operated by a well-known operation ascends the combustion tube 21 and is blown from the hot air fan 10 to the louver 9 from the hot air radiating section 11.
The hot air is discharged forward of the frame 1 through the discharge port 13, and the room is heated in the same manner as before.

In addition, since shielding plates 20 are formed on both sides of the louver 9 that do not face the hot air radiation part 11, the inner oil supply device, electrical components 15, wiring 18, etc. cannot be seen from these parts as in the conventional case. These are always shielded by the shielding plate 20 and are not exposed to the outside, so they do not spoil the aesthetics or cause discomfort to the user.Moreover, the shielding plate 20 prevents dust etc. Since the intrusion into the interior is also prevented, the parts can be used safely for a long period of time without worrying about malfunctions, abnormal combustion, cleaning, etc., and the life of the parts is also long.

Furthermore, since a small upright wall 12 is formed at the discharge port 13 of the louver 9, the strength is increased and the device is extremely convenient to use, since it does not become unsightly or its function deteriorates due to deformation or the like.

Also, since a gap 19 is formed above the shielding plate 20, the part of the louver 9 that does not face the hot air radiating part 11 is completely sealed by the shielding plate 20, and hot air accumulates in this part, causing electrical equipment, etc. There is no possibility that the frame 1 will malfunction or the frame body 1 will become hot, and as a result, no noise such as chattering noise will be generated.

As described above, this invention is designed to emit hot air through the louver 9 provided at a suitable position of the frame 1 housing the combustion mechanism 5 inside, and to use the heat exchange part of the louver 9 or the hot air blowout. At least a discharge port 13 is formed in a portion facing the hot air radiating portion 11, such as a portion, and at least a discharge port 13 is formed in another portion, and a smaller gap 19 is formed in the other portion by the discharge port 13. Since the louver is equipped with a shielding plate 20, hot air is discharged outside the frame through the outlet of the louver, heating the room. Since a shielding plate is provided, the inside of the frame facing this part is shielded by the shielding plate and is not exposed to the outside, so mechanical parts such as oil supply equipment, electrical components, wiring, etc. can be accessed from this part as in the past. The shielding plate prevents dust from entering the frame from this part, which prevents dirt from accumulating inside the frame. This part will not malfunction or cause abnormal combustion, and the life of the parts will be extended, so you can use it with confidence.Furthermore, there is a gap in the shielding plate, so the part that does not face the hot air radiating part is completely sealed by the shielding plate, preventing hot air from accumulating in this area and damaging electrical equipment, etc., and hot air being sucked in and the hot air that accumulated in this area being removed from the gap. The heating capacity is improved in the same way as in the past.

Furthermore, the structure is extremely simple, consisting of just adding a shielding plate to a conventional louver, and has various advantages such as being inexpensive and inexpensive.
