Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a bathroom heating device installed in a bathroom.

[Background Art] There is a bathroom heating device that uses hot water. This device is formed by housing a water jet motor 3 and a heat exchanger 4 in a main body case as shown in FIG. An advection pipe 6 is connected to the exchanger 4, and a hot water return pipe 11 is connected to the heat exchanger 4.
are connected to each other, and the hot water supplied through the hot water supply pipe 5 operates the water flow motor 3, and then this hot water is passed from the water flow motor 3 through the heat exchanger 4 through the advection pipe 6, and is returned through the hot water return pipe 11. be done. Then, air is sent to the heat exchanger 4 by the fan 2 which is rotationally driven by the operation of the water jet motor 2, and the hot air that has been heat exchanged and heated is discharged from the inside of the main body case, thereby generating hot air in the bathroom. It can provide heating.

When attaching the mirror 7 to the outer surface of the main body case in such a heating device, the mirror 7 is attached to prevent the mirror 7 from fogging up due to steam in the bathroom.
Attempts have been made to place a heat exchanger 4 on the back side of the mirror 7 and heat the mirror 7 with the heat exchanger 4. However, in this case, when hot water is passed through the heat exchanger 4 to prevent fogging of the mirror 7, the water flow motor 3 is also operated because the hot water is supplied to the heat exchanger 4 after passing through the water flow motor 3. However, since hot air heating is always required, there is an inconvenience in that it is not possible to only prevent the mirror 7 from fogging.

[Purpose of the invention] The present invention has been made in view of the above-mentioned points, and provides a heating device for a bathroom that can perform warm air heating and anti-fogging of mirrors, as well as only anti-fogging of mirrors. The purpose is to

[Disclosure of the Invention] The bathroom heating device according to the present invention includes a water jet motor 3 provided with a fan 2 and a heat exchanger 4 in a main body case 1, and hot water is supplied to the water jet motor through a hot water supply pipe 5. 3 to rotate the fan 2, and the hot water is transferred from the water jet motor 3 to the heat exchanger 4 through the advection pipe 6.
In the bathroom heating device, the heated air is exchanged through the fan 2 and discharged from the main body case 1.The heat exchanger is installed behind the mirror provided on the front side of the main body case 1. 4, and a bypass pipe 9 is connected between the three-way valve 8 provided in the hot water supply pipe 5 and the advection pipe 6, and the hot water is transferred from the water flow motor 3 to the heat exchanger. In addition to flowing the water to the heat exchanger 4 through the bypass 9 without passing through the water jet motor 3, it is possible to only prevent the mirror 7 from fogging. do.

The main body case 1 is formed into a substantially right triangular planar shape so that it can be installed in a corner of a bathroom 12 as shown in FIG. 3a. A drive chamber 13 is formed in the center of the main body case 1, a suction chamber 14 is formed in the upper end of the main body case 1, and a discharge chamber 15 is formed in the lower end of the main body case 1.
As shown in FIG. 1, there is a suction passage 16 between the drive chamber 13 and the suction chamber 14,
and are communicated with each other through a discharge passage 17. The suction chamber 14 is provided with a suction port 18, and the discharge port 15 is provided with a discharge port 19. Further, a water jet motor 3 and a heat exchanger 4 are installed in the drive section chamber 13, and the heat exchanger 4 is brought into contact with a heat sink 20 formed of a metal plate or the like stretched on the inner surface of the wall of the drive section chamber 13. be. A mirror 7 is attached to the outer surface of the wall of this drive section chamber 13. As shown in FIG. 3b, a storage section 21 is formed on the upper side of the drive section chamber 13 and a shelf 22 whose position can be adjusted up and down is provided, and a storage section 23 is also provided on the lower side of the drive section chamber 13. , storage section 23
A faucet 25 is provided on the front side of the discharge chamber 15 on the lower side.

A hot water supply pipe 5 connected to a boiler (not shown) etc. is installed inside the main body case 1.
This hot water supply pipe 5 is connected to the water motor 3. Further, an advection pipe 6 is connected between the water flow motor 3 and the heat exchanger 4, and an operation valve 24 is connected to the hot water return pipe 11 led out from the heat exchanger 4. 24 can be operated from the front of the discharge chamber 15, as shown in FIG. 3b.
The hot water return pipe 11 is connected to a boiler or the like.
Further, as shown in FIG. 2, the hot water supply pipe 5 is provided with a three-way valve 8, and a bypass pipe 9 is connected between the three-way valve 8 and the advection pipe 6. The switching operation of the three-way valve 8 can be performed, for example, by a switch provided near the mirror 7.

Then, the three-way valve 8 is switched to close the bypass pipe 9 and the operation valve 24 is operated to allow hot water to flow, and the hot water is caused to flow from the hot water supply pipe 5 to the water flow motor 3 and from the water flow motor 3 via the advection pipe 6. By flowing hot water through the heat exchanger 4 and returning the hot water through the hot water return pipe 11, the flow of hot water operates the water flow motor 3 to rotate the fan 2.
Air in the bathroom is sucked into the main body case 1 through the inlet 18 and blown against the heat exchanger 4, and heat is exchanged with the internal hot water on the surface of the heat exchanger 4 to generate warm air.
This warm air is discharged into the bathroom from the discharge port 19 by the force of the fan 2, thereby heating the bathroom with warm air. At this time, heat generated in the heat exchanger 4 due to the circulation of hot water is transferred to the mirror 7 via the heat sink 20.
The temperature is transmitted to the mirror 7, and the mirror 7 is heated to prevent the mirror 7 from fogging at the same time. Next, when only defogging the mirror 7 without performing hot air heating, switch the three-way valve 8 to close the flow of the hot water supply pipe 5 to the water jet motor 3 and open the bypass pipe 9. The hot water is made to flow directly from the hot water supply pipe 5 to the heat exchanger 4 through the bypass pipe 9 without being passed through the heat exchanger 3. That is, at this time, the water flow motor 3 is not operated because hot water does not flow, and instead of performing hot air heating, the mirror 7 is heated with the hot water flowing through the heat exchanger 4 to only prevent the mirror 7 from fogging. This is possible.

[Effects of the invention] As described above, in the present invention, hot water is passed through a hot water supply pipe to a water flow motor to rotate the fan, and hot water from the water flow motor is passed through a heat exchanger through a convection pipe to exchange heat. In a bathroom heating device that discharges hot air that has been heat-exchanged by a fan from the main body case, a heat exchanger is installed behind the mirror installed on the front side of the main body case, and a hot water supply pipe is connected to the heat exchanger. Since a bypass pipe is connected between the three-way valve and the advection pipe, hot water can be passed through the water motor and heat exchanger to simultaneously perform hot air heating and defogging the mirror using the heat exchanger. Of course, by switching with a three-way valve to flow hot water directly to the heat exchanger without passing it through the water jet motor, it is possible to only prevent the mirror from fogging without heating the hot air.
