Abstract

PURPOSE:To pour hot-water by the simultaneous heating of a tap-controlled water heater and a bath boiler in combination and realize a large capacity by a method wherein a hot-water pouring pipe is communicated with the inlet water tube boiler section of a bath heater through an upper circulating pipe and a pump and is communicated with a lower circulating pipe under the sequence of the inlet water tube boiler section, a heat transfer tube and an outlet water tube boiler section. CONSTITUTION:Hot-water, delivered from a tap-controlled water heater 1, is poured into a hopper through a hot-water delivery pipe 2, a hot-water pouring valve 4 and another hot-water delivery pipe 5, thereafter, is guided between a pump 9 and an inlet water tube boiler section 8 by a hot-water pouring pipe 7. The circulating direction of the pump 9 is from an upper circulating pipe 11 side to the inlet water tube boiler section 8 side, therefore, hot-water in the hot-water pouring pipe 7 is heated by the heat transfer tube 12 of a bath boiler and is poured into a bathtub 10 through a lower circulating pipe 14. When water is remaining in the bathtub 10, the pump 9 is operated to send the hot-water from the hot-water pouring pipe 7 and the water in the bathtub 10 into the heat transfer tube 12 whereby they are heated and circulated.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a combination of an instant water heater and a bath pot.The capacity of the bath pot is added to the capacity of the instant water heater to increase the capacity and provide hot water at an appropriate temperature. This relates to an automatic bath device that dispenses hot water into the bathtub (hereinafter referred to as pouring hot water), stirs the inside of the bath using a circulation pump, and automatically stops when the appropriate amount and temperature are reached.

Conventional technology Conventionally, when pouring hot water into a bathtub, the capacity of the bathtub was not added to the capacity of the bathtub; instead, water heated at a constant temperature in a water heater for 11 hours was sent into the bathtub via the bathtub, and then the circulation pump was turned on. The heater was used to stir the inside of the bathtub and reheat it at the same time, and automatically stopped reheating when the temperature reached the appropriate temperature.

That is, as shown in FIG. 2, the hot water outlet pipe 2 of the instantaneous water boiler 231 branches into the hot water outlet tap 3 side and the hot water pouring solenoid valve 15 side, and hot water flows through the hopper 6 and the hot water pouring pipe 7 on the Sumitomo side. Most of the hot water is poured into the bathtub 10 through the upper circulation pipe 11 and the remaining water is poured into the bathtub 10 through the heat exchanger 17 and the lower circulation pipe 14. Ta. Further, the circulation pump 18 is provided in parallel with the heat exchanger 17, and the suction port 19 is connected to the discharge port 20 in the lower circulation pipe 14.
was provided in the upper circulation pipe 11 in a double-port shape.

(Jettsu σ14 No. 10155) The problem that the invention attempts to solve In the old example, when pouring water into the bathtub, simultaneous heating by the boiler and the bath pot was not performed for one period. When this is done, the hot water discharged from the instantaneous water heater is simultaneously heated by the bath heater, and in order to increase the capacity, the hot water from the pouring pipe 7 flows to the upper circulation pipe 11 side and the heat exchanger 17 side. Therefore, there is a risk of empty heating of the bathtub, and the temperature of hot water poured into the bathtub is different depending on the hot water flowing out from the upper circulation pipe 11 and the hot water flowing out from the lower circulation pipe 14, which is higher in temperature only from the bath heater. Therefore, there was a problem that management was difficult.

The present invention solves such conventional problems, and the instant i7
! The hot water is poured by simultaneous heating of the 118 vessel and the bath pot, achieving a large capacity, and by accurately controlling the pouring temperature, it is possible to set the pouring temperature at a predetermined boiling temperature, reducing the minimum time required. The purpose is to boil it.

Means for Solving the Problems In order to solve the above problems, the hot water bath pot of the present invention communicates the hot water pouring pipe with the paddy field of the bath heater through the upper circulation pipe and the pump, and The daily water can section, the heat transfer tube, and the outlet water can section are connected in this order to the lower circulation pipe.

Effect With the above configuration, the pumped water dropped from the pouring pipe is
It flows through the bath heater's inlet tank, heat transfer pipe, outlet water tank, and lower circulation pipe, and is led to the bathtub. Further, when water accumulates in the bathtub and the pump is operated, the poured hot water and the water in the bathtub are guided in the same way as the above-mentioned path. Therefore, all of the pumped water passes through the bath pot, increasing capacity by simultaneously heating the instant water heater and bath pot, and shortening the time required for boiling.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In FIG. 1, the hot water outlet pipe 2 of the instantaneous water heater 1 is connected to the hot water outlet tap 3.
and an outlet pipe 5 having a pouring valve 4,
The outlet pipe 5 faces the hopper 6. The pouring pipe 7 has a hopper 6 on the upper side and communicates with a light blue inlet part 8 of the bath heater and a pump 9 on the lower side. In addition, the bath tfM1o includes an upper circulation pipe 11, a pump 9, an inlet light blue part 8, and a heat transfer tube 1.
2, the outlet water can part 13, and the lower circulation pipe 14 are connected in this order.

In the above configuration, the hot water discharged from the instantaneous water heater 1 is supplied to the hot water outlet pipe 2.
, the molten metal is poured into the hopper 6 through the molten metal pouring valve 4 and the molten metal outlet pipe 5. The poured hot water is guided between the pump 9 and the sunrise paddy field 8 by the pouring pipe 7. Since the circulation direction of the pump 9 is from the upper circulation pipe 11 side to the water tank section 8 side, the pouring pipe 7
There is almost no backflow of hot water in the direction of the upper circulation pipe 11, and the hot water is poured into the bathtub through the input paddy field 8, the heat transfer tube 12, the outlet water can 13, and the lower circulation pipe 14. All hot water can be heated in the bath pot, and by measuring the temperature with the outlet temperature sensor 15 and controlling the capacity of the instantaneous water heater 1, hot water at a predetermined desired temperature can be heated by the instantaneous water boiler capacity and the bath pot capacity. It is possible to pour hot water into the bathtub within the overall range of .

In addition, if there is residual water in the bath tJ110, by operating the pump 9, hot water from the pouring pipe 7 and water in the bathtub 10 can be sent into the heat transfer pipe 12, and the outlet temperature sensor 15 sets the hot water temperature. By comparing the temperature, the instantaneous water heater capacity can be controlled and hot water can be poured into the bathtub and circulated to the desired temperature. Due to the above effects, regardless of the presence or absence of residual water in the bathtub, instant G7 when pouring hot water! The capabilities of Ilf P+3 and the bath pot can be used in combination, and the time required from the start of pouring water to boiling can be shortened.

Effects of the Invention As described above, according to the present invention, in a hot water supply bath pot that combines a controlled NLD device and a bath pot, by specifying the configuration of the bath heater, hot water pouring pipe, and pump as in the present invention, Regardless of the presence or absence of residual water in the bathtub, the combined capacity of the instant water heater and bath pot can be used when pouring hot water, and by setting the hot water pouring temperature to the desired temperature, the required time from the start of hot water pouring to 1tJck is reduced. The time can be significantly reduced compared to conventional methods.
