Abstract

PURPOSE:To prevent cracks and damages of burner itself so as to improve its safety by disposing a pair of fore and aft heat receiving plates outside the burner. CONSTITUTION:A pair of fore heat receiving plate 10 and aft heat receiving plate 11 are disposed outside the burner 9 but inside the case 1 so as to distribute and guide the fluid from the fan 7 to four directions. According to this constitution, the fluid incoming from the air intake 2 is distributed and guided from the outlet 7a of the fan 7 to four directions by said pair of heat receiving plates 10, 11, and part of said fluid is discharged to the outside of the unit from the outlet 3 after exchanging heat with the burning chamber 9. As the rest of the fluid is blown along the inner wall of the case 1 out of said outlet 3, the case 1 will not be excessively heated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a heating device equipped with a combustor for high-load combustion.

(Technical backstory of the invention) Conventional heating devices used for home use and commercial use have a combustor installed in the upper part of a box-shaped case body equipped with an air inlet and an air outlet. 1 inside this combustor.
Heat transfer is improved by means such as arranging four 1AtJ units, and a blower is provided at the bottom of the case body.

Therefore, the fluid (air) flowing into the upper part of the case body from the inlet (to the top) exchanges heat in the combustor heated by the radiant heat from the radiant, and is discharged from the outlet to heat the room. It is supposed to be done.

[Problems with background technology]

However, when the above-mentioned warm ry 4 device is burnt under high load for a long time, the wall surface of the combustor becomes high temperature, metal materials have poor durability, and ceramic materials have poor durability. Since there is a large temperature difference between the inside and outside, there is a risk of cracking or damage due to the difference in thermal expansion.

On the other hand, in order to reduce the temperature difference between the inner and outer shells of a combustor made of ceramics, reducing wind radiation caused by fluid reduces the number of heat exchangers and reduces heat exchange efficiency.
Due to this, the cabinet 1 itself is heated by the radiant heat, which poses a safety problem.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and the present invention has been developed by disposing a heat receiving plate on the outside of the combustor to prevent cracks and damage to the combustor itself during high-load combustion over a long period of time. prevent,
In addition, the present invention provides an intravenous chamber device aimed at improving safety.

[Summary of the invention]

The present invention incorporates a radiator in a combustor of a case body equipped with an intake port and an air outlet, and arranges a pair of front heat receiving plates on the outside of the combustor to connect the radiator to the inside of the combustor. The structure is designed to reduce the temperature difference between the cabinet and the outside window to prevent cracks and the like, and also to prevent the temperature of the cabinet from rising.

[Embodiments of the invention] Hereinafter, the present invention will be described with reference to an illustrated embodiment.

In FIG. 1, reference numeral 1 denotes a box-shaped case body (cabinet), and an intake port 2 is formed at the lower front of the case body 1, and an intake port 2 is formed at the upper front of the case body 1. , a warm air outlet 3 is formed. or,
Inside the case body 1, there is a partition plate 6 that separates and forms an upper chamber 4 and a lower chamber 5. Inside this lower chamber 5, there is a blower 7 that blows hot air into the room. is installed so that its blowing lower a is communicated with the upper chamber 4. Further, a combustor 9 is provided in the middle of the upper chamber 4, and a radiator 8 made of a porous material is provided inside the combustor 9. Additionally, on the outside of the combustor 9 and on the inside of the case body 1, a pair of front heat receiving plates 10 and rear heat receiving plates 11 are provided from the air blower 817. The system is designed to divide the fluid into four directions and distribute the air. Note that both heat receiving plates io, i1
is made of a heat-resistant material with good radiation efficiency and its inner lining is coated with heat-resistant black paint.

Meanwhile, the above combustion! 59, an auxiliary heat exchanger 12 is provided via a communication pipe 13, and an exhaust pipe 14 is provided at one end of the auxiliary heat exchanger 12 through the back plate of the case body 1. It is attached.

Further, above the auxiliary heat exchanger 12, a flat heat shield plate 1 is provided.
5 is installed to prevent the top plate of the case body 1 from rising in temperature.

Therefore, during heating, after igniting the combustor 9, the
When f1l17 is driven, the fluid flowing in from the intake port 2 is transferred from the blowing lower a of the blower 1fi7 to both the heat receiving plates 10.
and 11, the air is distributed in four directions, and after exchanging heat with the combustor 9, a part of the fluid is blown out from the air outlet 3 to heat the room. Furthermore, since the remaining fluid is blown out from the outlet 3 along the inner wall surface of the case body 1, there is no risk that the temperature of the case body 1 itself will rise.

Next, another embodiment of the present invention shown in FIG. 2 has a window hole 10a and a transparent window 1a formed in the case body 1 and the front heat receiving plate 10, so that radiant heat can be utilized. It is.

Another embodiment of the present invention shown in FIG. 3 is a front heat receiving I! A diversion guide plate 16 is provided in the diversion section 17 located at the lower part of the heat receiving plate 110 and the rear heat receiving plate 11 to promote the diversion function of the fluid.

It should be noted that the design may be changed freely by attaching heat radiation fins to the inner sides of both heat receiving plates 10 and 11.

(Effects of the Invention) As described above, according to the present invention, a combustor 9 having a built-in radiator 8 is provided in the upper chamber 4 of the case body 1 provided with an inlet 2 and an outlet 3. A pair of front and rear heat receiving plates 10 and 11 are arranged on the outside of the combustor 9, which not only prevents cracks and damage caused by the heat of the combustor 9 itself, but also prevents the temperature of the cabinet from rising, improving safety. can be achieved.
