Description

[Detailed description of the invention] [Field of application and overview of the invention] The present invention relates to a bath pot with a water heater, and is a water heater of a type in which a hot water supply heat exchanger and a bath heat exchanger are housed in the body. This invention relates to a bathtub with a bathtub, and by rationally arranging each heat exchanger, a control device, and a piping system, it is possible to flatten the body of the bathtub.

[Prior art and its problems] Recently, there has been a strong demand for smaller and thinner bathtubs with water heaters, and moreover, the combustion capacity of this type of appliances has become larger.

Therefore, in order to reduce the size of a bathtub with a water heater using an atmospheric pressure burner, we proposed a method disclosed in Japanese Utility Model Application Publication No. 104183/1983. As shown in FIG. 5, in this device, a hot water supply heat exchanger 1 and a bath heat exchanger 2 are arranged side by side at the lower part of a container body 3, and the hot water supply heat exchanger 1 and the bath heat exchanger 2 2 is collected above the hot water supply heat exchanger 1 by the exhaust collecting pipe 51, and the exhaust from the exhaust collecting pipe 51 is discharged to the outside by the exhaust pipe 5. The control parts group 8 is housed in a space surrounded by the exhaust pipe 51 and the exhaust pipe 51.

In this device, the control parts group 8 is centrally arranged, and the space accommodating the control parts group 8 is divided by the partition plate 6 to accommodate the bath heat exchanger 2 and the hot water supply heat exchanger 1. Since it is separated from the installation section, thermal protection of the control parts group 8 is sufficient.

However, with today's demand for increased combustion capacity, simply replacing each burner with a forced-combustion burner (a type of burner that forcibly supplies combustion air) in this conventional type of appliance is insufficient. becomes larger.

Since the hot water supply heat exchanger 1 and the bath heat exchanger 2 are installed side by side, the housing space for the fan for supplying the combustion air cannot be rationally arranged. 3 becomes larger.

In addition, space is required for a group of electrical control parts including the fan, and the conventional system described above requires
This is because these cannot be accommodated in the empty space surrounded by the partition plate 6.

The present invention is based on the above-mentioned "heat exchanger 1 for hot water supply combined with burner 11 for hot water supply and burner 21 for bath".
A bathtub with a water heater in which a heat exchanger 2 for a bath in which a heat exchanger 2 is combined is housed in a body 3, and exhaust gas from these combustion parts is discharged from an exhaust port.
An object of the present invention is to make the entire appliance thinner when the burners corresponding to the hot water supply heat exchanger 1 and the bath heat exchanger 2 are forced combustion type burners.

[Technical Means] The technical means of the present invention taken to solve the above-mentioned problems is ``a bath heat exchanger 2 combined with a bath burner 21 in the lower part of the vessel body 3 and close to one side wall.
A hot water supply heat exchanger 1 is arranged and combined with a hot water supply burner 11 in close proximity to the other side wall of the upper part of the vessel body 3.
A forced exhaust fan 22 is provided above the bath heat exchanger 2, and a forced exhaust fan 22 is provided above the bath heat exchanger 2.
An air supply fan 12 is provided below, and an exhaust port 52 extending in the width direction is provided at the upper end of the container body 3, and this exhaust port portion is opened to the front of the container body 3. The exhaust box 55 at the upper end of 1 is connected to the exhaust port section 5.
2, and a forced exhaust fan 22.
A discharge port is connected to the exhaust port portion 52 through a communication pipe 23 along the rear wall of the vessel body 3, and is formed below the hot water heat exchanger 1 on the side of the bath heat exchanger 2. The gas control parts group 81 is arranged centrally in the space above the bath heat exchanger 2 and on the side of the hot water supply heat exchanger 1. The water supply connection part 83 and the hot water supply connection part 8 are connected from the side wall adjacent to the arrangement part of the control parts group 82
4 and the gas connection part 85 are made to protrude, and the gas control parts group 81 is made to protrude from the gas connection part 85.
A gas communication pipe 86 is arranged between the bath heat exchanger 2 and the gas control parts group 81, and the control board 4 equipped with electric parts is connected to the hot water supply heat It was arranged below the hot water supply heat exchanger 1 near the side wall adjacent to the exchanger 1.

[Operation] The above technical means of the present invention operates as follows.

Since the combustion parts of the hot water supply heat exchanger 1 and the bath heat exchanger 2 both employ a forced combustion method, the thicknesses of the front and rear of the hot water supply heat exchanger 1 and the bath heat exchanger 2 are made thinner. Even if set, sufficient combustion performance and heat exchange function will be exhibited.

In addition, since the hot water supply heat exchanger 1 and the bath heat exchanger 2 are arranged at vertically shifted positions, the body 3
These heat exchangers can be accommodated even if the left and right widths are small. In other words, the width of the appliance housing the hot water supply heat exchanger 1 and the bath heat exchanger 2 becomes smaller.

Further, since a sufficient space is created below the hot water supply heat exchanger 1 and on the side of the bath heat exchanger 2, the control parts group can be accommodated in this space. Moreover, since this space is located below the hot water supply burner 11 combined with the hot water supply heat exchanger 1, its thermal influence is small. Furthermore, the water system control parts group 82, which has a relatively small volume, can be efficiently accommodated in the space formed in front of the communication pipe 23.

[Effects] Since the present invention has the above configuration, it has the following unique effects.

Since the hot water supply heat exchanger 1 and the bath heat exchanger 2 can be made flat, the appliances can be made thinner. Furthermore, these heat exchangers and the set of burners combined with the heat exchangers are arranged rationally, creating a sufficient space to accommodate the gas control parts group 81 and the water system control parts group 82, which makes it easier to use than the conventional one. The width is also relatively small. In other words, the device has a small width and a thin front and rear thickness, and can be installed in a small space.

Furthermore, since the control board 4 is disposed in a portion that is less affected by heat, its durability is improved.
