Abstract

The present invention is a method for maintaining the temperature of the hot water in the tub, a sanitary device in the building equipment of general buildings, generally when the bath receives hot water in the bath, the temperature of the hot water is lowered for a sufficient time as the bath time passes Satisfactory bathing is impossible only when you cannot bathe or by replenishing hot water, and in this case, it is inconvenient to maintain the proper temperature. Therefore, this inconvenience is solved and the constant temperature can be maintained for a desired time. The hot water heated in the boiler passes the heating water supply pipe and heats the hot water in the bathtub in the heat exchanger installed at the bottom of the bathtub, returns to the boiler through the heating water return pipe, and installs a temperature sensor and a thermostat in the bathtub to match the desired temperature. As we can use, hot water in bathtub during bath It is possible to bathe for a sufficient time at a constant temperature without any inconvenience to go down and take a bath, and to install the facility simply because the existing boiler is used.

Description

Bath hot water heating method {omitted}

The present invention relates to a hot water heating method of the sanitary facilities of the building equipment of the general building as to ensure that the hot water of the bathtub does not cool during bathing and can be used according to the desired temperature and conventionally adds hot water when the hot water in the bathtub cools. Or a separate heater is used, but the present invention uses an already installed boiler, so no additional heating device is required and energy consumption is reduced.

According to the present invention, the hot water of the bathtub cools as time passes during the bath, so that the hot water maintains an appropriate temperature when the temperature decreases, and may further increase the temperature during the bath. As a heating method, a separate heating is performed by using a boiler that is already installed. There is no need to install equipment and the use of energy can be reasonably used by existing facilities.

During the bath ① When the temperature of the hot water in the bath drops, ⑤ detect the temperature of the hot water by the hot water temperature sensor, and ⑥ operate the boiler boiler switch ④ and the heating water circulation pump so that the temperature is adjusted to the temperature adjusted by the hot water temperature controller. The heated heating water is supplied to the heat exchanger (3) installed in the lower part of the bathtub through the heating water supply pipe (8), and the hot water in the bathtub is heated by the heat exchanger (9), passing through the heating water return pipe (9) and entering the boiler by pushing the heating water circulation pump. Heated and circulated again to heat the hot water in the bath through the heat exchanger to the proper temperature and to prevent backflow into the water supply pipe and the heating water return pipe when the water supply or heating water passes through the common water supply pipe and the heating water return pipe. It is configured to install a non-return valve on the water supply and heating water return lines.

The effect of the invention is that when the temperature of the hot water in the bath is lowered during the bath, it can be heated up to an appropriate temperature, and it can be raised to a desired temperature higher than that. By using an existing boiler, a separate heating device is unnecessary and energy waste can be reduced. have.

Claims (1)

① Install a heat exchanger at the bottom of the bathtub and install a hot water temperature sensor to detect the temperature of the hot water inside the bathtub. Connect the hot water temperature controller to the outside to match the desired temperature. ④ It is operated by connecting the heating water circulation pump and the boiler's ⑦ boiler switch. ② Boiler's high temperature heating water comes out. Bathtub hot water heating method characterized in that the hot water in the tub is maintained at an appropriate temperature through the heat exchanger to prevent the backflow by attaching a non-return valve to the pipe.
