Abstract

PURPOSE:To eliminate a hot water feed route for a hot floor mat use only and to heat a bath room through effective heating of a hot floor mat by means of hot water especially passed through a return route for additional heating, by a method wherein a hot water pass route for a hot floor mat is installed in a return route part to a heat exchanger for additional heating for a bath tub. CONSTITUTION:Hot water passing a hot water filling route 2 is fed to a bath tub 1, and an additional heating route 7 is adapted to reheat hot water in the bath tub. A hot floor mat 3 is connected to a return route 7a of the additional heating route 7, the hot floor mat is heated to a proper temperature by feeding a relatively low temperature hot water after additional heating to perform heating of a bath room. A heat exchanger and a fan 11 for blowing off hot air, adapted to blow off hot air, are situated in the additional heating route.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a bathroom heating device, and more particularly to a technique for effectively heating a bathroom with a simple configuration using a hotbed mat.

[Background technology] Conventionally, bathroom heating, especially floor heating, is carried out by using a hotbed mat and introducing hot water into a hot water passage formed in the hotbed mat. This is done using a separate system, and a separate route for supplying hot water to the hotbed mat must be constructed, which is costly and
The temperature of the hot bed mat must be controlled separately from the temperature of the hot water in the bathtub, and it is troublesome to control the temperature of the hot bed mat to an appropriate temperature, and the configuration for this purpose is also complicated. was there.

[Object of the invention] The present invention has been made in view of these problems,
Its purpose is to reheat hot water in the bathtub.
By incorporating a hotbed mat in the return route to the heat exchanger in the reheating route, it is possible to eliminate the construction work of constructing a hot water supply route exclusively for the hotbed mantle, reduce costs, and improve the return route especially for reheating. To provide a bathroom heating device capable of heating a bathroom by effectively heating a hot bed mat with passing hot water.

[Disclosure of the Invention] In the bathroom heating device of the present invention, in the reheating path 7 for reheating the hot water in the bathtub 1, a hot water passage path of the hot bed mat 3 is provided in the return path 78 to the reheating heat exchanger 9. 4, and by configuring it in this way, the above object is achieved. In other words, by incorporating the hot bed mat 3 into the return path 7a to the heat exchanger 9 of the hot water path 7 that reheats the hot water in the bathtub 1, it is possible to omit the construction of a dedicated hot water supply path to the hot bed mat 3. , while drastically reducing costs, especially hotbed mat 3.
Because heating is achieved using temperature-controlled hot water that passes through the return route 7a of the reheating route 7, the temperature does not exceed body temperature, making it possible to provide comfortable floor heating. Even when the person takes a bath later, not only the hotbed mat 3 but also the bathroom is appropriately heated, so that suitable heating can be performed at the time of taking a bath.

Embodiments of the present invention will be described in detail below based on the drawings.

As shown in FIG. 1, the hot water filling path 2 includes a water flow switch FS built into the heat source device 5, a water temperature detection thermistor TH, a heat exchanger 8 that uses steam fuel for hot water filling, and a water proportional pulp W.
C■, connected to the bathtub 1 via the bath solenoid valve BV, water flow sensor FSW, check valve AV, etc., so that hot water at an appropriate temperature can be supplied to the bathtub 1 to a substantially constant water level;
Also, the water level can be kept approximately constant depending on the use of hot water. In this way, pour hot water at an appropriate temperature into the bathtub 1.
As the structure for supplying hot water to a constant water level and the structure for maintaining the water level at a substantially constant level depending on the use of the hot water, well-known structures can be adopted.

Also, in the bathtub 1 there is a sutra that burns! r7 is connected, and a heat exchanger 9 for reheating uses fuel for reheating;
When the temperature of the water in the bathtub 1 drops below a certain level by the bathtub water temperature detection thermistor THb, pump P1 bath water flow switch FSWb, etc., the hot water in the bathtub 1 is led out from the return path 7a and passed through the heat exchanger 9. The hot water is automatically returned to the bathtub 1 to keep the water temperature approximately constant. Further, the reheating path 7 is provided with a hot air blowing device 10 having a grill G that opens into the bathroom, and by switching the switching valve (■) provided in the reheating path 7, the reheating state shown in FIG. The state shown in Figure 3 (a) that combines heating and hot air blowing, and the state shown in Figure 3 (a)
It is designed so that it can be switched to three states including a heating state exclusively for blowing hot air as shown in FIG. 3(b). The 7T ton 11 for blowing hot air can be operated in the summer without supplying hot water to the heat exchanger 9 and used for air conditioning, and can also be used for hot air drying, cold air drying, etc. when not bathing. It is something.

In the return route 7a of the reheating route 7, there is a hot water outlet 6 which has a hot water outlet and a hot water return outlet inside the bathroom.
A hot-bed mat 3 placed on the floor of the bathroom is connected to this hot-water outlet 6, and relatively low-temperature hot water for reheating is supplied to and passed through the hot-water passage path 4 of the hot-bed mat 3. By heating the hot bed mat 3, the hot bed mat 3 can of course also heat the bathroom.

In this way, by incorporating the hot bed mat 3 into the return path 7a to the heat exchanger 9 of the reheating path 7 that reheats the hot water in the bathtub 1, the construction of a dedicated hot water supply path to the hot bed mat 3 can be omitted and a large In order to reduce costs, especially the hotbed mat 3 is heated using temperature-controlled hot water that passes through the return path 7a of the reheating path 7. In addition, heating is always available when reheating the heat, and even when taking a bath later, not only the hotbed mat 3 but also the bathroom is appropriately heated, thus providing suitable heating when taking a bath.

(Effects of the Invention) In short, the present invention is advantageous because the hot water passage path of the hotbed mat is configured in the return route to the heating heat exchanger in the heating path for reheating hot water in the bathtub. Because the hotbed mat is built into the return route to the heat exchanger of the hot water heating route, it is possible to omit the construction of a dedicated hot water supply route to the hotbed mat, and while aiming to significantly reduce costs, it is possible to The mat can be heated with temperature-controlled hot water that passes through the return route of the reheating route, and the temperature is not higher than body temperature, making it possible to provide comfortable and safe floor heating. There is an advantage that heating can be done at all times, and even when taking a bath later, not only the hotbed mat but also the bathroom can be appropriately heated, so that suitable heating can be performed when taking a bath.
