Description

[Detailed Description of the Invention] The present invention relates to a hot water supply bath pot that includes a water heater and a bath pot.

BACKGROUND ART Conventionally, a hot water bath pot in which a bath pot and an instantaneous water heater are housed in one exterior is known, as shown in Japanese Utility Model Application Publication No. 49-115238.

However, this method of heating hot water in a hot water bath kettle uses instant water heating, so when the hot water is turned on again after a while after the hot water supply is stopped, the hot water that has been stagnant in the hot water heat exchanger becomes hot and comes out at a high temperature. This method has the disadvantage of causing an after-boiling phenomenon, and also has the problem of not being able to supply a large amount of hot water at once, which is inconvenient when supplying hot water to several locations at the same time or when inserting the water heater into a bathtub.

On the other hand, if a hot water storage type water heater with a hot water storage tank and a bath pot are installed side by side, there is no problem with the above-mentioned after-boiling when hot water is supplied, and a large amount of hot water can be supplied, but there is a problem that the installation area becomes large. In addition, in the case of a bathtub in which a hot water storage tank is arranged above the bathtub as disclosed in Japanese Patent Publication No. 41-11951, the height of the product is high and the structure is unstable, so a reinforcing structure is required. This resulted in the problem of increased product prices.

In view of these problems, the object of the present invention is to provide an inexpensive hot water bath pot that can supply a sufficient amount of hot water without any after-boiling, has a small installation area, and can be made low in height.

In order to achieve this objective, the present invention has the following structure.

In other words, a semi-hot water storage type water heater can is constructed, which consists of a water supply tank connected by a plurality of fin-added heating pipes and a single return pipe adjacent to the heating pipes, and a hot water tank placed above the water supply tank. The water supply tank and the hot water supply tank are extended on the return pipe side, a bath pot can body is provided below the space formed between the two tanks in the extension part, and a hot water supply burner is provided below the fin-added heat pipe. A bath burner is arranged below the bath pot can body.

Due to this configuration, the present invention allows the water heater can body and the bathtub can body to be installed side by side without increasing the installation area of the product, and the height of the product can be lowered, resulting in a more compact product. In addition to contributing to the
Moreover, the amount of hot water stored in the water tank and the extension on the return pipe side of the hot water tank is increased compared to a normal semi-hot water storage type can.
This makes it possible to realize a hot water bath pot that can supply a sufficient amount of hot water without overheating.

An embodiment of the present invention will be specifically described below based on the drawings.

1 is a main body of a hot water bath pot, and inside the main body 1 there is a water tank 4 connected to a plurality of fin-added heating pipes 2 and a single return pipe 3 adjacent to the heating pipes 2, and an upper part of the water tank 4. It has a semi-hot water storage type water heater can body 6 consisting of a hot water tank 5 and a hot water tank 5 arranged therein.
Further, the water supply tank 4 and the hot water supply tank 5 are extended from the return pipe 3 side to form a space 7 between the two tanks in the extended portion.

Below the return pipe 3 and the space 7 is provided a bathtub can body 10 having circulation pipes 8 and 9 for connection to a bathtub (not shown).

11 is a hot water supply burner 1 that heats the fin-added heat tube 2;
2 is a combustion chamber, and 13 is a combustion chamber of a bath burner 14 that heats the bath pot can body 10.

Reference numeral 15 denotes a collective exhaust stack whose lower end communicates with the reburning chamber 11.13. A partition plate 16 is provided between the heating pipe 2 and the return pipe 3 in the collective exhaust stack 15, and the partition plate 16 separates the combustion chamber 11 from the combustion chamber 11. An exhaust chamber 17 that communicates with the combustion chamber 13 and an exhaust chamber 18 that communicates with the combustion chamber 13.
It is divided into two parts.

19 is a water supply pipe, 20 is a hot water pipe, 21 is a heating coil for heating arranged in the hot water tank 5, 22 is a tank installed in parallel with the hot water tank 5, and 23 is a circulation pump installed outside the main body, which dissipates heat. The heating water returned from the vessel (not shown) first passes through the tongue 22,
Water is pressurized by the circulation pump 23, passed through the heating coil 21, heated within the coil 21, and supplied to the radiator.

24 is a heat shield cylinder having a U-shaped cross section that shields the return pipe 3 from the combustion heat of the bath burner 14;
It is installed on 6th.

25 is a thermostat provided in the hot water supply tank 5, and the thermostat 25 controls the combustion of the hot water supply burner 12.

The present invention has the above-mentioned configuration, and when hot water is not being supplied, a circulation circuit is formed consisting of the water supply tank 4 → fin additional heat pipe 2 → hot water supply tank 5 → return pipe 3 → water supply tank 4, and the inside of the hot water supply tank 5 is set by the thermostat 25 Hot water is stored at a constant temperature, and when hot water is supplied, the stored hot water is supplied from the hot water supply pipe 20.

Therefore, as described above, according to the present invention, one side of the water supply tank 4 and the hot water supply tank 5 is extended, and the can body 10 for the bathtub is disposed below the space between the two tanks in this extended part. Therefore, the water heater can body 6 and the bath boiler can body 10 can be installed side by side without expanding the installation area of the product, and the amount of hot water stored in the can body 6 can be reduced only by the extension of the water tank 4 and the hot water tank 5. It is possible to obtain a hot water supply bath pot with a large capacity for storing hot water.

Furthermore, as shown in this embodiment, by extending the water supply tank 4 and the hot water supply tank 5 toward the return pipe 3 side, and installing the bath pot body 10 below the space 7 and the return pipe 3, the product can be made smaller. can be expected to be even more effective.

In this case, the return pipe 3 does not receive the combustion heat of the bath burner 14 due to the heat shield cylinder 24, so the circulation effect is not inhibited and hot water can be stored effectively.
