Description

  The present invention relates to a heater for heating a room with combustion gas generated by combustion in a burner section.

Conventionally, in this type of apparatus, a burner portion is directly provided in the heat radiating portion, and the front surface of the flat box-shaped heat radiating portion is heated to dissipate heat, thereby trying to heat the room well. (For example, refer to Patent Document 1.)
Japanese Patent No. 3566887

  By the way, in this conventional one, since the combustion gas in the burner part flows directly to the heat radiating part, heating unevenness occurs in the heat radiating part, and uniform and efficient heat radiation cannot be obtained, and the heat is concentrated in the part. There was also a risk of burning.

This invention pays attention to this point and solves the above-mentioned problems. In particular, the structure is composed of a heat dissipating part that circulates the combustion gas generated by the combustion of the burner part and dissipates heat, and a front surface that becomes a heat dissipating surface in the heat dissipating part Provided with a partition plate that partitions the side and a rear side having an inflow port and an outflow port of combustion gas, the partition plate is provided with a ventilation means composed of a plurality of small holes, and the small holes are provided with the combustion gas. The central part facing the inflow port is made dense and the end facing the outflow port is formed to be rough, or the small hole in the central part facing the inflow port is made larger than the small hole facing the outflow port It is.

According to the first aspect of the present invention, the combustion gas is supplied by the partition plate over the entire front surface of the heat radiating portion and is uniformly dispersed, so that the front surface of the heat radiating portion is heated uniformly, resulting in local burnout. Without having to worry about it, you can always get comfortable heating with good heat dissipation.
Part of the combustion gas that flows in from the inlet flows into the front surface of the heat radiating section through these small holes, and the rest flows into the front surface of the heat radiating section from the gap at one end of the partition plate. And the entire front surface of the heat dissipating part can be reliably heated, and good heat dissipation can be obtained.
In addition, the formation of small and rough small holes prevents red heat caused by overheating of the front surface of the heat dissipation part so as not to give the user anxiety, and the central small hole is made larger than the small holes on both sides Then, the combustion gas efficiently flows over the entire front surface of the heat radiating portion, and good heat radiation can be obtained.

Next, a heater according to the present invention will be described based on an embodiment shown in the drawings.
Reference numeral 1 denotes a burner unit which receives combustion air supplied from the combustion fan 2 and fuel supplied from a fuel supply means (not shown) and burns to generate combustion gas.

Reference numeral 3 denotes a prismatic combustion cylinder located on the burner portion 1 and communicated with the burner portion 1, and a flat middle heat dissipating portion 4 communicates with the upper portion.
The rear side of the heat radiating part 4 has a shape protruding slightly outward, and has a combustion gas inlet 5 at the center of the rear side, and an outlet 6 on the right side.

7 is a partition plate provided in the center so as to divide the inside of the heat radiating part 4 back and forth, and a plurality of small holes 8 having a diameter of 3.5 mm are formed here almost 150 to form the ventilation means 9, and the upper end is formed at the upper end. A restraining plate 10 that covers the inflow port 5 is formed.
The attachment is made by three-point spot welding of the lower and upper two points for sound prevention.
On the other hand, a far red paint is applied to the front side of the heat radiating section 4 to radiate far infrared rays, and a plurality of beads 11 are formed for reinforcement.

  Reference numeral 12 denotes a heat exchanger through which the combustion gas after passing through the heat radiating portion 4 circulates. The heat exchanger 12 is arranged on the back surface of the heat radiating device 4 and has a plurality of pipes arranged in parallel. Thus, the air blown by driving a convection fan (not shown) is discharged into the room as hot air by heat exchange.

  Next, the operation of this embodiment will be described. The combustion gas generated by the combustion of the burner section 1 now flows from the combustion cylinder 3 through the inlet 5 into the heat radiating section 4 where the combustion gas is separated from the partition plate 7. However, since the ventilation means 9 is formed at a position facing the inlet 5, it passes through a plurality of small holes 8 that are the ventilation means 9, and a part thereof. The combustion gas circulates in the front surface in the heat radiating section 4 and heats the front surface, thereby radiating far infrared rays from the heat radiating section 4 to perform good heating.

  On the other hand, the combustion gas that has passed through the small hole 8 on one side of the partition plate 7 after heating the heat radiating part 4 and the combustion gas that has flowed in from the inlet 5 and has not passed through the ventilation means 9 are discharged from the side of the heat radiating part 4. 6 flows into the heat exchanger 12, and the indoor air from a convection fan (not shown) is warmed by heat exchange to heat the room warm.

  The partition plate 7 is for suppressing the flow of a large amount of combustion gas to the front surface in the heat radiating section 4 and adjusting it so as to emit far infrared rays while preventing red heat. As shown in FIG. 3, when the small holes 8 have the same size, as shown in FIG. 3, the small holes 8 in the central portion facing the inflow port 5 are formed densely and separated from them. In order to prevent the user from feeling uneasy by preventing red heat due to overheating of the front surface of the heat radiating portion 4.

  Further, when the size of the small hole 8 is changed, as shown in FIG. 4, the small hole 8 in the central portion facing the inflow port 5 is made larger than the small holes 8 on both sides, thereby burning from the central portion of the partition plate 7. By sending a large amount of gas to the front surface of the heat dissipating part 4 and reducing both sides, the combustion gas efficiently flows over the entire front surface of the heat dissipating part 4 and good far-infrared radiation can be obtained.
