Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a humidifier that is incorporated into a combustion device that has a vaporization section that evaporates and gasifies liquid fuel such as kerosene and light oil, and its purpose is to evaporate and gasify liquid fuel. Heat the heat pipe using the electric heater used in An object of the present invention is to provide a humidifier that can be taken out.

Next, a conventional example will be explained based on FIG. 2. This conventional example has a configuration in which a blowout grille 2 is provided on the front side of a hot air fan body 1 and an indoor air intake port 3 is placed on the back side. A heat exchanger 6 with stacked cylinders is arranged, connected to an exhaust pipe 7 at the rear, and a supply cylinder 8 communicating with an air supply/exhaust fan 4 is provided inside the exhaust pipe 7. Further, a hot air fan 9 is provided at the rear of the heat exchanger 6 to send hot air toward the blow-off grill 2. In addition, a hot water storage tank 1 is placed on the top surface of the heat exchanger 6.
9' is placed.

In this case, during combustion in the combustion section 5, the air supply/exhaust fan 4 is driven, fresh air from outside is introduced from the supply cylinder 8, is combusted in the heat exchanger 6 which also serves as a combustion cylinder, and is exhausted to the outside from the exhaust cylinder 7. Exhaust gas. Next, the warm air fan 9 provided at the rear of the heat exchanger 9 is driven, and indoor cold air is introduced from the indoor air intake port 3 on the back of the hot air fan body 1 to exchange heat as it passes through the heat exchanger 6. Warm air is blown out from the blow-off grill 2. Further, the liquid in the hot water storage tank 19' disposed in contact with the upper part of the heat exchanger 6 is heated by heat conduction accompanying combustion and evaporates into vapor, thereby humidifying the indoor atmosphere.

In this case, the hot water tank 1 is heated by exchanging heat with the combustion exhaust gas.
9', the heating temperature of the hot air tank 19' decreases and the amount of humidification decreases, making it impossible to obtain the desired amount of humidification if the heating temperature of the hot air tank 19' is set to a low value. . In addition, the combustor itself repeats ON-OFF control when the indoor temperature approaches the set temperature due to a room thermometer, etc.
There may be times when no heat conduction occurs in the hot water storage tank 19', and humidification may not be possible.

The present invention attempts to solve the above-mentioned conventional drawbacks by transmitting the heat of a liquid fuel vaporization section provided with an electric heater to a hot water storage tank via a heat transfer means such as a heat pipe.

An embodiment of the present invention will be described below with reference to FIG.

In this embodiment, a blowout grille 2 is provided on the front side of the hot air fan body 1, and an indoor air intake port 3 is placed on the back side, and a combustion section 5 connected to an air supply/exhaust fan 4 is provided, and the upper part of the hot air fan body 1 also serves as a combustion tube. A heat exchanger 6 is arranged, and an exhaust pipe 7 at the rear is connected to the heat exchanger 6. Furthermore, a supply cylinder 8 is connected to the supply and exhaust fan 4 in the exhaust pipe 7.
is provided. Furthermore, a hot air fan 9 is provided at the rear of the heat exchanger 6 to blow out hot air toward the blowing grill 2.

The combustion section 5 is provided with a vaporization cylinder 10, an annular electric heater 11 is embedded in the internal peripheral wall or bottom of the vaporization cylinder 10, and one end of an annular heat pipe 12 is embedded in the vicinity thereof. A burner head 13 is provided in the upper part of the vaporizer cylinder 10, and a combustion flame 14 is formed. A liquid atomizing nozzle 16 is arranged in the air supply passage 15 of the supply/exhaust fan 4, and a tank 18 is connected to this via a fuel pump 17.

Further, one end of the heat pipe 12 is immersed in a liquid (such as water) in a hot water storage tank 19 located near the hot air blowing grill 2. The hot water storage tank 19 has an evaporation port 20 on its upper surface, and is further connected to a water supply and drainage device consisting of a water supply passage 22 provided with a water supply pump 21 and a hot water supply port 24 provided with a valve 23.

The following operation will be explained.

After preheating the vaporizer cylinder 10 in the combustion section 5 with the electric heater 11 until the temperature of fuel such as kerosene or diesel oil can be maintained at a sufficiently high temperature compared to the boiling point, the fuel pump 17 is driven and the fuel in the tank 18 is heated. The liquid is guided to the liquid atomizing nozzle 16 and heated to the vaporizing cylinder 10.
Evaporate it inside. This hourly supply exhaust fan 4 is driven, fresh air is introduced from the supply cylinder 8, combustion air is introduced from the supply passage 15, and the air is discharged from the burner head 13 in a premixed state with the vaporized gas, and the igniter ( (not shown) to form a combustion flame 14 outside the burner head 13. The heat exchanger 6 is heated by the heat of the combustion flame 14 and the exhaust gas, and the exhaust gas is discharged from the exhaust pipe 7 at the rear.
At this time, the hot air fan 9 is driven to bring the cold air introduced from the indoor air intake port 3 into contact with the heated outer circumferential wall of the heat exchanger 6 for heat exchange, and hot air is blown into the room from the blow-off grill 2.

Here, one end (evaporation part) of the heat pipe 12 embedded in the vaporization cylinder 5 is heated by receiving the heat of the electric heater 11 and the heat of the combustion flame 14. Then, heat is transferred to the other end (condensation part) of the heat pipe 11 immersed in the liquid in the hot water storage tank 19 to heat the liquid, generate evaporated gas, and generate hot air from the evaporation port 20 and the blowout grill 2. Blow out. In addition, the water supply pump 21 constituting the water supply and drainage system is driven to introduce liquid from a liquid supply source (not shown) into the hot water storage tank 19 via the water supply passage 22, and the valve 23 is opened to supply warm water from the hot water supply port 24. You can also get it.

In order to heat one end of the heat pipe 12 embedded in the vaporizer cylinder 5 in this way, and immerse the other end in the liquid to transfer the heat from the vaporizer cylinder to humidify and supply hot water,
The electric heater 11 is always energized to maintain a constant temperature so that the vaporizer tube 5 always evaporates kerosene or light oil to generate vaporized gas. For this,
Heat can be received regardless of whether the combustor is controlled on or off by the room thermometer, and even if the combustion amount is set low, the temperature is still set above the boiling point to evaporate kerosene, so it is always constant. The heat of the vaporization tube can be conducted to the other end of the heat pipe 12.
Therefore, a sufficient amount of humidification can always be ensured. Furthermore, hot water can be stably secured according to the amount of water fed by the water supply pump 21.

Moreover, even when there is no combustion, by simply heating the vaporizer cylinder 5, it can be used as a humidifier or a water heater, allowing for a wide range of applications.
