Description

[Detailed description of the invention] The present invention relates to a bath device, and more specifically, a bath device that automatically controls the operation of an oil gasification type combustor that requires preheating, the supply of hot water to a bathtub, and the maintenance of an appropriate amount of hot water and an appropriate temperature. Regarding.

Conventionally, in bath equipment where a combustor vaporizes and burns liquid fuel such as kerosene, a person supplies water to a predetermined water level in the bathtub and stores it, and then a person ignites the combustor to open the heat exchanger. The water in the bathtub was heated to a predetermined temperature.

For bath equipment equipped with a combustor such as a gas burner, it is relatively easy to automate the operation from hot water supply to maintaining a specified temperature by simply turning on the pilot burner, and such equipment has not existed in the past. Various types are known.

However, for products that require preheating, such as oil gasification combustors, people must open and close the water tap and operate the combustor, especially when water is first supplied, making full automation difficult. It was thought that.

The combustor 1 is provided with a preheater 25 for vaporizing a certain amount of fuel such as kerosene supplied to the combustor from a supply nozzle 21 by the fuel supply device 19, and further preheats the combustor 1 to a predetermined temperature. Preheating detection element 2 that detects whether or not
6 is provided.

The reference numeral 11 indicates a flue surrounded by an upper tank 5 and a lower tank 9. The lower end of this flue 11 is opened into the combustion chamber of the combustor 1, and the upper end of the flue 11 near the upper tank 5 is An exhaust pipe 12 is connected, and this exhaust pipe 12 is opened to the atmosphere.

Reference numeral 18 denotes a fuel tank for kerosene or the like, which is communicated with the fuel supply device 19 through a fuel supply pipe 20; 22, a blower for supplying air to the combustion chamber; 23, one end is connected to the suction side of the blower 22; An intake duct whose end opens to the atmosphere, and reference numeral 24 indicate a blower duct whose one end is connected to the discharge side of the blower 22 and whose other end is connected to the combustion chamber.

By the way, the normally closed solenoid valve 14 arranged in the water supply pipe 3 is
It is electrically connected to the preheat detection element 26 and the water level detection element 17 of the combustor 1, and when the combustor 1 is preheated and reaches a predetermined temperature, the preheat detection element 26 detects this, and the water level in the bathtub reaches a predetermined temperature. When the water level becomes below, the water level detection element 17 detects this and sends a signal to each of the electromagnetic valves 14 for opening operation.

When the water level in the bathtub exceeds a predetermined level, the electromagnetic valve 14 is closed by a signal from the water level detection element 17 that detects this.

A flow switch 15 provided in the water supply pipe 3 is electrically connected to a fuel supply device 19 and a blower 22, and is connected to a solenoid valve 14.
When water begins to flow into the water supply pipe 3 due to the opening of the The fuel is ignited and burned.

Further, the fuel supply device 19 and the blower 22 are also electrically connected to the temperature detection element 16.
The combustor 1 operates even when the water temperature is detected to be below a predetermined value, causing the combustion operation of the combustor 1, and stops the combustion operation when the water temperature reaches a predetermined value or higher.

Next, the operation of the bath device configured as above will be explained.

When the water tap 13 installed in the middle of the water supply pipe 3 connected to the water source is opened, the combustor 1 is heated by the preheater 25 after being energized in advance, and when the predetermined temperature is reached, the preheat detection element 26 is activated. The solenoid valve 14 opens, and the flow switch 15 opens.
Water is supplied into the upper tank 5 through the water supply port 8 at the tip of the water supply pipe 3.

This water flows into the upper tank 5 in contact with the temperature detection element 16, is rectified in the water reservoir 7, passes through the heat exchanger 2 and the lower tank 9, and flows through the lower circulation pipe 10 while forming an approximately double-shaped waterway. and is supplied into the bathtub 4.

At this time, the flow switch 15 is turned on to operate the fuel supply device 19 and the blower 22, and the ignition device (not shown) is activated as appropriate, so that the fuel supplied to the combustor 1 is ignited and combusted.

Thereby, the water passing through the above-mentioned path is transferred to the upper tank 5,
It is heated in the heat exchanger 2 and the lower tank 9, and is supplied into the bathtub 4 as hot water.

Note that the temperature detection element 16 is set to a predetermined temperature,
When the water temperature is lower than a predetermined temperature, the combustor 1 is operated to burn,
The operation is stopped when the temperature exceeds a predetermined temperature.

In this way, hot water is stored sequentially from the bottom of the bathtub 4 upwards, and when the hot water in the bathtub 4 reaches a predetermined water level, the water level detection element 17 detects the water head difference H in the bathtub 4 and closes the solenoid valve 14 to automatically supply water. Stop.

In this state, if the temperature of the water in the bathtub 4 is low, the combustor 1 performs continuous combustion, and circulating heating returns from the bathtub 4 to the bathtub 4 via the lower tank 9, the heat exchanger 2, and the upper tank 5.

In this way, when the hot water in the bathtub 4 reaches a predetermined temperature, the temperature detection element 16 detects this and simultaneously stops the operation of the fuel supply device 19 and the blower 22, thereby stopping combustion by the combustor 1.

When the temperature of the water in the bathtub 4 becomes low, the temperature detection element 1
By the operation 6, the fuel supply device 19 and the blower 22 are operated, combustion is automatically performed in the combustor 1, and the temperature of the water in the bathtub 4 is always constant.

Further, when the water level in the bathtub 4 falls below a predetermined level, the water level detection element 17 operates to open the electromagnetic valve 14 to supply water, and the amount of hot water in the bathtub 4 is always maintained constant.

As mentioned above, according to the bath device of the present invention, even if the bath device is equipped with an oil gasification type combustor that requires preheating, the preheating detection element and the solenoid valve provided in the water supply pipe are provided in the combustor. By controlling the opening and closing by a water level detection element, and by controlling the combustion operation of the combustor by a flow switch and a temperature detection element provided in the water supply pipe,
Once the preheating heater of the combustor is energized, hot water at a predetermined temperature will accumulate in the bathtub at a predetermined water level, and the hot water that has accumulated at a predetermined water level will be maintained at a predetermined temperature at all times by automatic control of the water temperature detection element and the combustor. As a result, it is possible to provide a bathing device that is truly easy to operate, with no need to monitor the hole or operate the water supply valve or combustor each time.
