Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a wood-burning heater that allows you to enjoy the atmosphere of a fireplace.

(Prior Art) As a conventional heater of this kind, one is known that is provided with a combustion chamber having a simulated firewood therein, and the flame of the simulated firewood is generated by the flame of a burner provided below the simulated firewood.

(Problem that the invention aims to solve) However, even if the flame of the burner is configured to make it look like firewood is burning, the flame of the burner is narrower than the flame when firewood is actually burning, and the overall flame is The volume of the fluctuation is lacking.

Therefore, a reflector was installed on the wall of the combustion chamber to reflect the burner flame, and the burner flame was reflected on the reflector in an attempt to obtain a sense of volume from the flickering flame. However, with this, the flame was reflected too clearly on the reflector, so the flame was simply seen further back, and the sense of volume from the flickering flame was not obtained. Also, although the flame was reflected and the interior was brighter, the brightness in the back of the combustion chamber was only partial, from the burner flame, and the soft, dim brightness of actual firewood burning was not obtained, so there was an inconvenience in that it was not possible to obtain the atmosphere of a fireplace.

(Means for Solving the Problems) The present invention aims to provide a wood-fired heater that eliminates the above-mentioned inconveniences, and is equipped with a combustion chamber containing simulated firewood inside, and uses the flame of the simulated firewood to simulate the flame of the firewood. In those consisting of the flame of a burner installed below the firewood,
The present invention is characterized in that a reflection plate for reflecting the flame is provided on the wall of the combustion chamber, and a reflectance reducing member is applied to the reflection plate.

(Function) The present invention has the above-mentioned configuration. According to this, the flame of the burner is blurred and reflected on the reflector, so that a sense of volume of flame fluctuation can be obtained, and the interior is relatively bright and warm.

(Example) Next, an example of the present invention will be described based on the drawings.

In the drawing, 1 indicates a firewood-type heater, and the heater 1 has a combustion chamber 3 equipped with a pseudo-firewood 2 inside, a heat exchange section 4 provided on the back side of the combustion chamber 3, and a heat exchange section 4 provided on the right side of the combustion chamber 3. A storage chamber 5 equipped with other electrical components 5a for combustion control, and a hot air fan 6 provided below the heat exchange section 4.
, a hot air outlet 7 provided on the front side, a gas burner 8 below the pseudo firewood 2 for forming a flame of the pseudo firewood 2, and a gas burner 9 for heating the pseudo firewood 2 to red heat. It is housed and installed in the recess provided.

The combustion chamber 3 has a glass plate 10 and a wire mesh 11 on the front side.
An opening 10a is provided in a part of the glass plate 10 to serve as a secondary air intake port for the gas burners 8 and 9, and a pseudo firewood 2 made of ceramic material or the like is provided at the bottom. . In addition, the pseudo firewood 2 is heated red-hot by the blue flame formed by sufficiently supplying primary air from the gas burner 9 provided below and in front of the pseudo firewood 2. The red flame formed by restricting the primary air of the gas burner 8 installed at the lower rear of the firewood makes it appear as if the pseudo firewood 2 is burning, giving a visual sense of heating. I made it.

Incidentally, the burner 8 is composed of four cylindrical burners, and the burner 9 is composed of a horizontally installed pipe burner.

The heat exchange section 4 is connected to the combustion chamber 3 at the upper front surface and is composed of three flat exhaust passages that communicate with each other, and the combustion exhaust gas that has passed through the heat exchange section 4 is passed through an exhaust duct that communicates with the back surface of the heat exchange section 4. 13 and is discharged outside the room. Note that 14 indicates a blower interposed in the exhaust duct 13.

Here, in the present invention, a reflection plate 15 for reflecting the flame of the burner 8 is provided in the combustion chamber 3, and a reflectance reducing member 16 is applied to the reflection plate 15. Specifically, the combustion chamber 3 A reflector plate 15 made of stainless steel or the like is attached to the rear chamber wall and side chamber wall of the reflector plate 1.
5 was coated with a black heat-resistant coating as a reflectance reducing member 16 to reduce the reflectance to about 20%.

When doing so, the combustion chamber 3 of the wood-fired heater 1
By reflecting the flame of the gas burner 8 on the reflective plate 15 provided in the frame, a sense of volume can be obtained from the fluctuation of the flame of the gas burner 8, and the interior can be made relatively bright and warm, and furthermore, as in this embodiment, glass Even when the plate 10 is provided, even if the flame of the burner 8 is reflected on the glass plate 10, the flame of the burner 8 that would be reflected when the reflectance reducing member 16 is not provided on the reflector plate 15 will not be reflected, so the flame will not be reflected several times. It is invisible and can eliminate unsightliness.

In the above embodiment, the reflectance reducing member 16 is formed by painting, but it may be formed by a thin film formed by physical means such as vacuum deposition, or by chemical means such as plating.

In the drawing, 17 is an intake port of the warm air fan 6 provided on the bottom surface of the wood-type heater 1, and 18 is the intake port 17.
The filter installed in the figure is shown.

(Effects of the invention) As described above, according to the present invention, since a reflectance plate with a reflectance reducing member is provided in the combustion chamber containing the pseudo firewood, a sense of volume can be obtained in the fluctuation of the flame of the burner, and the combustion chamber The interior of the fireplace is not only lit by the burner's flame, but by providing a gentle glow throughout, allowing you to enjoy the atmosphere of a real fireplace.
