Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to a heating device that heats a floor surface, etc., using exhaust heat from a combustor.

<Prior Art> As seen in Japanese Utility Model Application Publication No. 51-126052, a heat exchange unit is placed above a combustor to produce hot water for floor heating, which is then circulated to a radiator.

<Problems that the invention aims to solve> However, the conventional system simply places a heat exchange unit above the combustor, and therefore there is a risk that it will easily fall off during earthquakes or other vibrations or shocks. Yes, it was dangerous.

Further, the heat exchange unit was inconvenient because it could only be mounted on a combustor with a specific size and top plate width.

<Means for solving the problem> This invention focused on this point and developed an almost inverted L-shaped heat exchanger consisting of a heat exchanger, a heat medium tank, a circulation pump, etc. on the top and back of the combustion chamber of the indoor exhaust type. In a heating device in which the unit is detachably carried on the back, a stopper is screwed to the side of the heat exchanger placed on the top plate of the combustor so that it can move forward and backward, and the stopper is used as a guide to move the heat exchanger back and forth. A locking fitting that can be slid in any direction and has a bent piece whose tip locks the front of the top plate, securely fixes the replacement unit, and can be installed even if the width of the top plate of the combustor is different. It is.

<Function> Next, when the heating device is used, exhaust gas or exhaust heat passes through the top plate 4 due to combustion in the burner 2, heats the heat exchanger 8, and exchanges heat.

As a result, the temperature of the heat medium in the heat exchanger 8 is raised, and the heat medium tank 10 → circulation pump 9 →
The heat is circulated in the order of the radiator 12 and the heat exchanger 8, and the radiator 12 radiates heat for heating.

At this time, the combustor 1 may vibrate for some reason,
Or, when it receives an impact, the heat exchange unit 5 itself is fixed by the bent piece 17 of the locking metal fitting 14 and the wall surface of the rear part b of the heat exchange unit 5, and therefore, the heat exchange unit 5 is accidentally dropped from the combustor 1. There is no chance of escape and it is safe.

Of course, depending on the size of the combustor 1 (the width of the top plate), it can be securely attached by adjusting the locking fitting 14, which is very convenient.

<Embodiment> Next, an embodiment of this invention will be described with reference to the drawings. 1 is a combustor such as an indoor exhaust type portable stove having a burner 2, a reflector 3 is provided behind the burner 2, and a reflector 3 is provided above the burner 2. It is composed of a top plate 4 etc. that transmits exhaust gas or exhaust heat.

5 is a heat exchange unit that can be detachably attached to the top and back of the combustor 1, and is attached to the outer frame 6.
is formed into a substantially inverted L-shape, with flow ports 7 opened above and below the front part a of the upper part, and a coil-shaped heat exchanger 8 installed inside, and furthermore, a heat exchanger 8 is installed inside the rear part b. One unit houses a heat medium tank 10 which communicates with one end and is connected to a circulation pump 9.
The other end of the heat exchanger 8 extends as a return pipe 11 and is connected to a radiator 12 that supplies a heat medium, and an outgoing pipe 13 extending from the circulation pump 9 is also connected to the radiator 12.

Reference numeral 14 denotes a locking metal fitting having a plate-like or L-shaped cross section, which can be slid freely on the left and right sides of the front part a of the heat exchange unit 5, and is fixed with a stopper 15 such as a screw as necessary. Although it has a short shape, it can be slid by opening a guide groove 16 using a stopper 15 as a guide in the longitudinal direction and loosening a stopper 15 such as a screw screwed onto the outer frame 6 of the heat exchange unit 5. It is fixed by tightening the stopper 15, and thereby the bent piece 17 provided at the tip is moved back and forth.

That is, when attaching the combustor 1 and the heat exchange unit 5, the heat exchanger 8, which is the front part a, is placed on the top plate 4, and the rear part b is brought close to or in contact with the rear wall surface of the outer frame 6.

After that, loosen the stopper 15 on the front part a and the locking metal fitting 14
is slid to lock the bent piece 17 in front of the top plate 4, and at this position the stopper 15 is screwed and tightened.
Also, if the width of the top plate 4 of the combustor 1 is narrow, the locking metal fitting 14 can be slid backward, and if the width of the top plate 4 is wide, the locking metal fitting 14 can be adjusted by sliding it forward. However, the entire heat exchange unit 5 is fixed between the bent piece 17 and the rear part b of the heat exchange unit 5.

<Effects of the invention> As described above, according to this invention, the heat exchange unit can be easily and securely fixed to the combustor with a simple configuration, and even if vibrations or impact are applied to the combustor, the heat exchange unit can be easily and reliably fixed to the combustor. The exchange unit is safe without falling off, and even if the front and back widths of the combustor or the top plate of the combustor are different, the heat exchange unit can be freely adjusted and reliably installed.
