Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a steam generator having a bathroom heating function.

2. Description of the Related Art A conventional steam generator of this type was constructed as shown in FIG.

That is, an evaporator 2 is disposed above the burner 1, a water supply means (not shown) is connected to a part of the evaporator 2, and a steam outlet 4 disposed in a part of the bathroom 3 is connected to the evaporator 2. The evaporator 2 was connected to the evaporator 2 through a steam pipe 5.

The evaporator 2 is heated by the heat generated by the burner 1, and the water supply means (
(not shown) is evaporated, and the generated steam is ejected into the bathroom 3 from the steam outlet 4 via the steam pipe 5, humidifying the bathroom 3.

Problems to be Solved by the Invention However, with the above configuration, scales such as silica and calcium contained in water precipitate inside the evaporator 2, clogging the evaporator 2 and impairing heat transfer. In order to heat the bathroom, holes must be made in the heat exchange wall, which requires installation of water softening treatment equipment and descaling means, which not only makes the equipment expensive and complicated, but also makes it difficult to heat the bathroom. It was necessary to heat the Tokibanko bathroom while wetting it with steam, and to increase the heating capacity, the evaporator 2 also had to be enlarged, making the equipment even more expensive and *N. It had

The present invention solves such conventional problems, and aims to generate steam and heat a bathroom by performing evaporation using an evaporator without providing a water softening treatment device or a scale removal means.

Means for Solving the Problems In order to solve the above problem Sa, the steam generator of the present invention includes an air heat exchanger, a water heat exchanger, a heating means for heating these heat exchangers, and a bathroom heat exchanger. An intake port provided at the top, a circulation fan that communicates with the intake port through an intake duct, a ventilation passage that communicates the outlet of the circulation fan with an air heat exchanger, and a part of the bathroom. the air outlet,
A cold air duct that communicates the outlet with the outlet of the air heat exchanger, and an atomization means that is connected to the outlet of the water heat exchanger and is arranged so as to face a part of the steam duct. A switching valve is provided between the atomization means and the water heat exchanger, a heating means is provided at the bottom of the bathroom, and a hot water pipe is provided to communicate the heating means and the switching valve. It has the following configuration.

According to the above-described structure, the air heat exchanger and the water external exchanger are heated by the operation of the heating means.

The air in the bathroom is sucked in from the air intake by the circulation fan S.
It reaches the air heat exchanger via the intake duct and ventilation passage,
Here, it is heated to become high-temperature air and supplied to the steam duct. - Water supplied from the power water supply means is heated by the water heat exchanger to become high-temperature water and reaches the atomization means, where it is atomized and discharged into the steam duct. The high-temperature mist comes into contact with the high-temperature air in the steam duct, and then emit the mist.
This high-temperature saturated warm air containing steam is ejected into the bathroom from the outlet. The high-temperature saturated humid air is cooled by the low-temperature air in the bathroom, resulting in a drop in saturated vapor pressure and the generation of condensed water mist, creating a steam sauna. Next, when operating the bathroom heating system, heating can be achieved by simply operating the air heat exchanger and circulation fan system, but if the water is not running, the water heat exchanger will heat up and the water inside will boil, which is dangerous. Therefore, the route of the switching valve is switched from the atomizing means side, and the heated water that has passed through the water heat exchanger is supplied to the heating means disposed at the bottom of the bathroom via the hot water pipe.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG. 1 of the accompanying drawings.

In FIG. 1, a water heat exchanger 7 and an air heat exchanger 8 are arranged above the burner 6, and a fuel supply means 9 supplies fuel for the burner 6, and a combustion means 9 supplies combustion air. The fan 10 forms a heat source section. On the other hand, an air intake port 12 is provided at the top of the bathroom 11.
2 and the intake duct 3 are connected to a circulation fan 14. The outlet of this circulation fan 14 is connected to the air heat exchanger 8 via a ventilation passage 15. An air outlet 16 disposed in a part of the bathroom 11 is connected to an outlet of an air heat exchanger 8 via a steam duct 17. An atomizing nozzle 18 is arranged on the outlet side of the water heat exchanger 7,
This atomizing nozzle 18 is arranged so as to face a part of the air intake duct 7. A pressure pump 19 is disposed on the inlet side of the water heat exchanger 7. A switching valve 20 is provided between the atomization nozzle 18 and the water heat exchanger 7, and the water heat exchanger 7
is connected to a floor heating panel 21 disposed at the bottom of the bathroom 11 through a hot water pipe 22.

In the above configuration, when the heat source section starts operating, combustion starts in the burner 6 by combustion air sent from the combustion fan 10 and fuel sent from the fuel supply means 9, and heat is generated, and the air heat exchanger 8 and the water Heat exchanger 7 is heated. The air in the bathroom 11 is passed through the air intake port 12 by the circulation fan 14.
The air is sucked in and delivered to the air heat exchanger 8 via the air intake duct 13 and the air blowing passage 15, where it is heated to become high-temperature air and supplied to the printing plate duct 17. On the other hand pressure pump 19
The water supplied is heated in the water heat exchanger 7 and heated to 50
The water becomes high-temperature water around °C and reaches the atomization nozzle 18, where it is atomized and discharged into the steam duct 7.

Here, the high-temperature mist evaporates while coming into contact with high-temperature air within the steam duct 17, and the high-temperature saturated humid air containing this steam is ejected into the bathroom 11 from the outlet 16. Since the high temperature saturated humid air is cooled by the low temperature air in the bathroom 11, a mist of condensed water is generated due to a decrease in saturated steam pressure, creating a steam sauna. Next, during bathroom heating operation, heating is possible by only operating the air heat exchanger 8 and circulation fan 14 system, but if water is not flowing, the water heat exchanger 7 will be heated and the water inside will boil. Therefore, the route of the switching valve 20 is switched from the atomizing nozzle 18 side, and the heated water that has passed through the water heat exchanger 7 is transferred to the hot water pipe 22.
Floor heating panel 21 installed at the bottom of bathroom 11 via
supply to By doing so, dry warm air comes out from the outlet 16 to heat and dry the inside of the bathroom 11, and the floor heating panel 21 further warms the feet.

Effects of the Invention As described above, according to the steam generator with bathroom heating of the present invention, the following effects can be obtained.

(1) Since steam is generated from high-temperature mist using high-temperature wind without using an evaporator, if the atomization means is stopped, the bathroom can be heated with dry warm air, so the bathroom can also be dried. Moreover, heating capacity can be increased simply by increasing the capacity of the air heat exchanger.

(2) During heating operation, the switching valve installed between the atomization means and the water heat exchanger is switched, and heated water is supplied to the heating means installed at the bottom of the bathroom, thereby heating the feet. It can be done efficiently.
