Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a snow melting device for melting snow on a roof, and more specifically to a snow melting stove used as a heat source for snow melting.

(Prior Art) Snow that accumulates on a roof has various negative effects on a house due to its weight and sliding off the roof. Particularly in regions with heavy snowfall, the amount of snowfall is extremely large, causing damage such as destruction or damage to houses. For this reason, in areas with heavy snowfall, it is necessary to remove snow to prevent it from accumulating on roofs above a certain level.
A great deal of effort and money is spent on removing this snow.

Therefore, in these snowy regions, various measures are taken to rationally remove the snow on roofs, and one method is to eliminate snow accumulation by melting the snow with heat. There are methods, devices, etc.

(Problems to be Solved by the Invention) However, conventional devices for removing snow using heat generally have problems in that they are complicated or large-scale, and are not easy to install.
In addition, with devices that melt snow by circulating hot air under the roof, if the temperature of the hot air is low, water droplets accumulate in the attic, increasing humidity and causing damage to the house.

Therefore, the present invention was devised to solve the above-mentioned problems, and its purpose is to effectively melt snow by using it suitably as a heat source for a device that melts snow on roofs. Our goal is to provide snow melting stoves that can be used to melt snow.

(Means for solving the problems) In order to achieve the above object, the present invention has the following configuration.

That is, a combustion section 12 that burns fuel such as petroleum to generate heat is provided so as to surround the side and top surfaces of the combustion section 12, and a through hole through which air heated by the combustion section 12 passes is provided on the top surface. an internal reflector 18 provided at the inner reflector 18; a high temperature chamber 16 provided surrounding the upper side of the internal reflector 18 into which the heated air is introduced; A blower fan 28 is installed in the high temperature chamber to introduce air and send the heated air to a duct 26 connected to and attached to the high temperature chamber; 16, and a cooling fan 36 that forcibly cools the motor 32 by air cooling.

(effect) Next, we will discuss the effect.

The air heated in the combustion section 12 is introduced from the internal reflector plate 18 into the high temperature chamber above it by the blowing action of the blower fan 28 driven by the motor 32. The air introduced into the high temperature room is turned into hot air and sent out from the duct 26 by the blower fan 28. The motor 32 located above the high temperature room 16 is cooled by a cooling fan 36 to maintain normal operation.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a sectional view showing an embodiment of a snow melting stove according to the present invention. In the figure, numeral 10 is the base of the snow melting stove, which houses a furnace core for burning fuel. Reference numeral 12 denotes a combustion section erected on the base section 10, in which a cylindrical combustion cylinder is installed concentrically. Note that the combustion section of the embodiment is of a type that gasifies oil and burns it. A through hole 14 is provided on the outer circumferential surface of the combustion section 12 to take in air for combustion.

A high temperature chamber 16 is provided above the combustion section 12 to collect the air heated in the combustion section 12. A through hole communicating with the combustion section 12 is bored in the bottom of the high temperature chamber 16, and the air heated in the combustion section 12 is introduced into the high temperature chamber 16 through the through hole. Further, the periphery of the combustion section 12 is surrounded by an internal reflector 18, and the outer periphery of the internal reflector 18 is further surrounded by an external reflector 20.
In the embodiment, an internal reflector 18 and an external reflector 20
surrounds the combustion section 12 in a rectangular shape.

The lower edges of the inner reflector 18 and the outer reflector 20 are provided at a slight distance from the upper surface of the base part 10 in order to supply air to the combustion section 12, and the upper ends of the inner reflector 18 and the outer reflector 20 are The space connected to the bottom of the high temperature chamber 16 and formed between the combustion section 12, the internal reflector 18, and the external reflector 20 communicates with the high temperature chamber 16. A plurality of communication holes 22 are formed on the side surface of the internal reflection plate 18.

Reference numeral 24 denotes a ventilation chamber provided in the upper part of the high temperature chamber 16, and an opening for circulating hot air is formed in the center of the partition plate between the high temperature chamber 16 and the ventilation chamber 24. The upper surface of the ventilation chamber 24 is a sealed plate, and the ventilation chamber 2
4 is provided with an outlet in one lateral direction. 26 is a duct connected to the outlet of the ventilation chamber 24.

Reference numeral 28 denotes a fan disposed in the ventilation chamber 24 corresponding to the opening, and sends air from inside the high temperature chamber 16 to the outlet side.

Reference numeral 28 denotes a motor storage chamber provided further above the ventilation chamber 24, and houses a motor 32 that rotationally drives the fan 28. A plurality of thin disc-shaped heat radiating plates 34 for heat radiation are fixed to the outer peripheral portion of the motor 32.

A cooling fan 36 is fixed to a side plate of the motor storage chamber 30 and blows air toward the motor 32 from the side. The motor storage chamber 30 is a sealed space, and an inlet 38 is provided on the side of the motor storage chamber 30 on the back side of the cooling fan 36 to allow air to flow in. An air outlet 40 is provided. Reference numeral 42 denotes a guide plate that surrounds the sides of the cooling fan 36 and the heat sink 34 so that the airflow caused by the cooling fan 36 does not escape to areas other than the heat sink 34.

Note that 44 is a cart on which the snow melting stove described above is placed, and 46 is a control unit that controls combustion of the snow melting stove.

Next, the operation of the above-described embodiment will be explained. The internal reflector 18 and the external reflector 20 act to reflect the heat generated in the combustion section 12, and the air heated within the combustion section 12 and by the radiant heat flows into the high temperature chamber 16 above. do. The fan 28 sends out the heated air flowing into the high temperature room 16 in the direction of the duct 26 as hot air.
The operation of the fan 28 creates a flow of air that constantly flows in the direction of the blower chamber 24, but by providing the internal reflector 18 and the external reflector 20, the heat of the combustion section 12 can be effectively utilized. Hot air can be suitably introduced into the high temperature chamber 16. Note that the communication holes 22 provided in the internal reflector 18 are connected to the combustion section 12.
It is designed to prevent the fire inside from being extinguished and to improve air circulation.

The hot air sent into the duct 26 by the fan 28 has an extremely high temperature, ranging from 300°C to 400°C in experiments.
It had a temperature of about Therefore, the temperature inside the ventilation chamber 24 inevitably becomes extremely high, and the motor 32 that drives the fan 28 cannot withstand the high temperature under normal conditions. Therefore, in this invention, the motor 3
A heat sink 34 is provided on the motor 32, and the heat sink 34 is further cooled by a cooling fan 36.
can be placed directly above the ventilation chamber 24 and used. External air is introduced into the motor housing chamber 30 from the inlet 38 by the cooling fan 36, passes through the heat sink 34, and flows out from the exhaust port 40.

Since the air flowing out from the exhaust port 40 is heated when passing through the heat sink 34 and exits as warm air, it can also be used for indoor heating.

The above-mentioned snow melting stove uses the heat of a room heating stove to generate hot air, and has the characteristic that extremely high temperature hot air can be easily obtained.

Note that FIG. 2 is an explanatory diagram showing a method of melting snow by guiding hot air from the above-mentioned snow melting stove to the roof. This installation method is characterized by forming a narrow layered space under the roof that allows hot air to flow, and blowing the warm air from the underside of the eaves toward the ridge. In the figure, 26 is the duct,
It is connected to the snow melting stove mentioned above. 50
is a blow-off duct which is horizontally suspended directly under the roof material under the eaves of the roof, communicates with the duct 26, and is provided with small holes for blowing out hot air at predetermined intervals in the longitudinal direction. Reference numeral 52 denotes a hot air flow path that sends hot air to the ridge side of the roof, and is formed in a layered space almost parallel to the roof. This warm air flow path 52 is provided with an opening 54 at the ridge portion so as to communicate with the outside of the roof. Reference numerals 56 and 57 are opening/closing plates for switching the direction of hot air flowing out from the opening 54.

In the embodiment, the temperature of the hot air at the blowout position of the blowoff duct 50 is about 100°C to 150°C, and about 60°C at the opening 54 on the ridge side. In this way, the hot air sent out from the snow melting stove maintains a fairly high temperature and flows through the hot air flow path 52, so that water droplets do not accumulate in the hot air flow path 52 during snow melting and the hot air does not become damp. This is a major effect of circulating high-temperature hot air. Furthermore, since the hot air passage 52 is formed in a narrow space, the hot air can be carried to the ridge without lowering the temperature. In this way, the warm air flows from the blow-off duct 50 to the entire roof in the direction of the opening 54 above, and the snow on the roof can be suitably melted. The opening/closing plate 5
Reference numerals 6 and 57 are for adjusting the blowing direction of hot air according to the wind direction, etc., and adjusting the blowing amount of hot air.

Note that the number of ducts connected to the hot air flow path 52 is not limited to one location, and the ducts may be installed in different rooms. This allows the snow melting stove to be moved as needed to heat the room and melt snow from the roof at the same time.

In some cases, the snow melting stove described above may be used without the duct 26, and in this case, it can be placed indoors to form a simple drying room. In some cases, hot air may also be directed directly at the snow to melt it. If the snow-melting stove is mounted on the cart 44 as shown in FIG. 1, it can be easily transported indoors, and the snow-melting stove can be easily moved to a predetermined position, making it easy to handle.

The present invention has been variously explained above using preferred embodiments, but the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That's true.

(Effects of the invention) As mentioned above, the snow melting stove of the invention has the following features:
It can be used to both heat a room and melt snow on the roof at the same time, and is characterized by being extremely easy to handle. In addition, this snow melting stove can obtain extremely high temperature hot air with a simple device, so it can effectively melt snow. Furthermore, since the hot air is at a high temperature, water droplets will not fall even when the hot air is passed under the roof, so there is no risk of damaging the roof. In addition, since it is similar in shape to a normal stove, it has great effects such as easy handling.
