PURPOSE:To reduce a hot-water temperature in a bathtub without pouring water to save a charge for city water. CONSTITUTION:The device is provided with a heat exchanger, provided with a heat transfer tube 14 for bath boiler for heating water in a bathtub 12, which is circulated by a circulating pump 11 to effect additional heating, a burner 13 for heating the heat exchanger 10, a fan 19 for sending air necessary for combustion, and a controller 21 for controlling the burner 13 and the circulating pump 11 in accordance with an operating signal from a remote controller 24. When the hot-water temperature in the bathtub 12 is to be reduced, the controller operates only the circulating pump 11 and the fan 19 to cool the hot-water in the bathtub 12, circulated by the circulating pump 11, by air sent from the fan 19.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reheating device for boiling water in a bath.

[0002]

2. Description of the Related Art A conventional reheating device has a structure shown in FIG. In FIG. 2, a burner 2 for heating the heat exchanger 1 and a circulation pump 5 for circulating the water in the bathtub 4 are provided in the bath heat transfer pipe 3, and a water pipe (not shown) is provided above the bathtub 4. ) Was provided with a faucet 6 connected by a pipe.

In this conventional reheating device, the bathtub 4
When boiling the water inside, the water in the bathtub 4 is circulated to the heat exchanger 1 by the circulation pump 5, and is heated by the burner 2 through the bath heat transfer tube 3 in the heat exchanger 1 and is heated in the bathtub. It was returned to 4. Further, when it is desired to lower the hot water temperature in the bathtub 4 according to individual taste, tap water is poured from a faucet 6 provided above the bathtub 4 to lower the hot water temperature in the bathtub 4.

[0004]

However, in the conventional structure as described above, the temperature of the hot water in the bathtub 4 is lowered by pouring tap water from the faucet 6 provided above the bathtub 4 as desired. However, since tap water is poured from the faucet 6, there is a problem that the amount of water in the bathtub increases and the tap water is wasted.

The present invention is intended to solve the above-mentioned conventional problems, and an object thereof is to prevent tap water from being wasted when tap water is not poured when lowering the bath temperature. is there.

[0006]

In order to achieve the above object, the reheating device of the present invention heats the water in the bathtub circulated by the circulation pump for circulating the water in the bathtub. A heat exchanger having a bath heat transfer tube for heating, a burner for heating the heat exchanger, a fan for feeding air for burning the burner, a fan, the burner and the circulation pump from a remote control device. A control device for controlling according to the operation signal is provided, and the control device operates only the circulation pump and the fan that sends air to the heat exchanger when cooling the hot water in the bathtub.

[0007]

According to the present invention, the hot water in the bathtub is circulated to the heat exchanger by the circulation pump and the temperature of the hot water in the bathtub is lowered by the air blown from the fan to the heat exchanger.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the reheating apparatus of the present invention will be described below with reference to the drawings. FIG. 1 is a system diagram of a reheating device according to an embodiment of the present invention. In FIG. 1, a heat exchanger 10 is provided with a bath heat transfer tube 14 for heating water in a bathtub 12 circulated by a circulation pump 11 with a burner 13. The burner 13 has a heater 17 for evaporating the fuel blown by the nozzle 16 from the pulse pump 15, and a fan 19 driven by a motor 18 for feeding the air necessary for burning the vaporized fuel. Is provided with a blower port 20. 21
Is a control device for reheating switch 22 and cooling switch 2
The fan 19, the burner 13, and the circulation pump 11 are controlled in response to a signal from the remote control device 24 including the control unit 3.

Next, the operation will be described. When reheating the water in the bathtub 12, the reheating switch 22 provided in the remote control device 24 is pressed, so that the water in the bathtub 12 is transferred from the bathtub 12 to the bath water in the heat exchanger 10 by the circulation pump 11. It is heated by the heat pipe 14 and circulated to the bath 12. On the other hand, when the temperature of the hot water in the bathtub 12 is lowered, the cooling switch 23 provided in the remote control device 24 is pressed,
The hot water in the inside is circulated from the bathtub 12 by the circulation pump 11, cooled by the air blown from the fan 19 in the bath heat transfer tube 14 in the heat exchanger 10, and circulated to the bathtub 12.

A temperature detector 25 for detecting the temperature of the hot water in the bathtub 12 is provided in a bath return pipe 26 connected to the heat exchanger 10 via the bathtub 12 and the circulation pump 11, and the bathtub 1
By providing a temperature control knob 27 for controlling the temperature of the hot water in 2 in the remote device 24, the temperature control knob 27
The hot water temperature can be automatically lowered until the temperature detector 25 detects the temperature set in step 2.

As a result, there is no need to inject water for cooling the hot water in the bathtub 12, and the hot water in the bathtub 12 can be lowered without wasting the tap water and further circulating the hot water in the bathtub 12 to lower the hot water temperature. You can bathe comfortably without uneven temperature.

A temperature detector 25 and a temperature control knob 27 are also provided.
In the case where the above is provided, the temperature can be automatically lowered to the temperature of the hot water in the bathtub 12 set by the temperature control knob 27, and the bath can be comfortably bathed without the trouble of manually opening and closing the faucet.

[0013]

As is apparent from the above-described embodiments, the reheating apparatus of the present invention is such that when the hot water temperature in the bathtub is lowered, the hot water in the bathtub is circulated by the circulation pump to circulate the hot water in the heat exchanger. Since the temperature is lowered by the air blown from the fan, there is no need to inject water to lower the temperature of the hot water in the bathtub, and the water bill can be saved without wasting tap water. Furthermore, since the temperature of the hot water is lowered while circulating the hot water in the bathtub, there is no unevenness in the temperature of the hot water so that you can take a comfortable bath.

Further, in the case where the temperature detector and the temperature control knob are provided, it is possible to automatically lower the temperature of the hot water in the bathtub set by the temperature control knob, and the trouble of manually opening and closing the faucet is required. You can comfortably take a bath.
