Abstract

PROBLEM TO BE SOLVED: To reduce the cost, heat the inside of a bath room before entering the bath room, and facilitate the maintenance by disposing a ventilating fan and a waste heat exchanger outside the bath room, and heating exhaust air in the bath room with waste heat of a hot water supplier upon heating and circulating it into the bath room. SOLUTION: A ventilating fan 12 is provided together with a waste heat exchange unit 5 in a hot water supplier chamber 6 outside and adjoining the bath room 2. Exhaust air in the bath room 2 is taken in by a ventilating fan 12 as indicated by an arrow 31, and is heat exchanged and heated using waste heat from a hot water supplier 3 as a heat source in the waste heat exchange unit 5. The amount of circulation of exhaust air is adjusted by an exhaust air adjusting valve 10 disposed below the waste heat exchange unit 5, and the heated exhaust air is blown off as warm air in the bath room 2 as indicated by an arrow 33 from a gap between a grill plate and a ceiling surface. Thus, waste heat exhausted upon combustion in the hot water supplier 3 is used as a heat source to heat the inside of the bath room 2.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a heating device used for heating a bathroom.

[0002]

2. Description of the Related Art Although it is widely said that a bathroom is cold, conventionally, only a bath dryer is a specific technique for solving it.

[0003]

However, since the above-mentioned bath dryer is expensive, the installation rate is low, and even if it is actually installed, the amount of electricity used is large and the running cost is high. , The rate of use is low.

Further, as a problem in practical use, it is necessary to heat the room in advance because it is necessary to heat the room when entering the bathroom, and it is necessary to heat after entering the bathroom. However, in reality, since the heating switch is turned on when taking a bath, it takes time for the heating to start up, which does not eliminate the coldness when taking a bath.

Therefore, an object of the present invention is to provide a heating device for a bathroom, which can reduce the cost, can perform heating before entering a room, and can be easily maintained.

[0006]

According to the present invention, a part or all of ventilation exhaust gas from a bathroom is warmed by waste heat of a water heater during heating and is circulated in the bathroom. A heating device for a bathroom, wherein a fan is arranged outside the bathroom together with the waste heat exchange unit.

[0007]

According to the present invention, the temperature of the waste gas of the water heater becomes low through the waste heat exchange unit, while a part or all of the exhaust gas taken in from the ventilation fan heats the waste heat from the water heater. As a result, heat is exchanged and warmed in the waste heat exchange unit, and is circulated as heating air in the bathroom. In such a configuration, since the ventilation fan is provided outside the bathroom together with the waste heat exchange unit, maintenance can be performed only from outside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a system diagram for explaining a schematic configuration of a heating device (1) for a bathroom according to an embodiment of the present invention. A water heater (3) and a waste heat exchange unit (5) connected to the water heater (3) are installed outside the bathroom (2). In this waste heat exchange unit (5), the exhaust gas from the water heater (3) is used in the bathroom.
(2) Considering that it does not enter inside, it is desirable that the heat pipe type is airtightly finished, does not mix with contaminated air, has high efficiency, and is easy to handle.

Further, outside the bathroom (2), the bathroom is
In the water heater room (6) adjacent to (2), the ventilation fan (12) is provided together with the waste heat exchange unit (5). FIG.
FIG. 3 is a simplified cross-sectional view for explaining the ventilation fan (12) and its surroundings. For this ventilation fan (12), what is called a sirocco fan, for example, is used.
(12) is housed and supported in a fan case (15) having an exhaust pipe (14), and takes in exhaust gas from the axial direction and flows it in the outer peripheral direction. Ventilation fan in this fan case (15)
At the outer peripheral end portion forming the intake port (18) on the upstream side of (12),
The upper end of the intake pipe (19) is fixed, and the grill plate (20) is attached to the lower end of the intake pipe (19), and the mesh plate (21) provided on the grill plate (20) is connected to the intake pipe (19). It is fixed with the mouths aligned. At this time, the grill plate (20) and the ceiling surface
A gap is formed with (42). In addition, (24) is the bathroom
It is the ceiling wall of (2).

An exhaust gas regulating valve (10) is installed below the waste heat exchange unit (5), and the amount of circulated exhaust gas is regulated by adjusting the valve (10).

In the above structure, the heating operation is
For example, when the water heater (3) is operated, the circulation type ventilation device (40) is operated at the same time, and the exhaust gas discharged from the water heater (3) becomes low in temperature through the waste heat exchange unit (5), and the arrow mark It is discharged to the outside as shown in the (30) direction (see FIG. 1).

On the other hand, the exhaust gas in the bathroom (2) passes through the intake passage (22) formed by the intake pipe (19) from the net portion (21) which is the intake port, as shown by the arrow (31). The fan case (1) as shown by the arrow (32).
It is discharged from the exhaust pipe (14) of 5) and is a waste heat exchange unit.
In (5), the waste heat from the water heater (3) is used as a heat source for heat exchange and warming. And the valve under the waste heat exchange unit (5)
At (10), the circulated amount of the exhaust gas is adjusted, and the warmed exhaust gas is supplied to the air supply pipe (23) as indicated by an arrow (34).
As a result, hot air is blown from the gap between the grill plate (20) and the ceiling surface (42) into the bathroom (2) as indicated by the arrow (33).

As described above, since the interior of the bathroom (2) is heated by using the waste heat exhausted when the water heater (3) burns, the running cost can be reduced and the water heater can be used. (3) Bathroom to supply heat source during operation (2)
You can warm the bathroom (2) before entering. Further, in such a configuration, since the ventilation fan (12) is combined with the outdoor waste heat exchange unit (5) and both are provided outside the bathroom, the ventilation fan (12), the waste heat exchange unit (5) and Since the water heater (3) is located all over the room, maintenance inside the bathroom (2) is unnecessary and noise can be prevented.

[0014]

As described above, according to the present invention, since the waste heat discharged during combustion in the water heater is used as a heat source, it is possible to significantly reduce the cost, and moreover, while the water heater is operating. Since the heat source is supplied to the bathroom, the inside of the bathroom can be warmed before entering the bathroom, and since the ventilation fan, the waste heat exchange unit and the water heater are located outside the room, maintenance inside the bathroom becomes unnecessary. Also, it becomes possible to prevent noise in the bathroom.
