Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a bath device, and more specifically, a high-temperature fluid ejector that ejects high-temperature fluid for heating bath water supplied from a high-temperature fluid generation source into bath water. It is placed below the standard bathtub water level and attached to the wall of the bathtub, and it blows high-temperature fluid such as steam, hot water, or a mixture of these into the bathtub water to directly heat the gas or liquid. The present invention relates to a bath device that efficiently boils bath water by replacing the bath water.

[Conventional technology]

Conventionally, in the above-mentioned bath equipment, the high-temperature fluid jet is disposed below the standard bath water level, that is, the high-temperature fluid is reliably jetted into the bath water, so that the high-temperature fluid is scattered into the air. precautions were taken to prevent direct contact with the human body.

[Problem that the invention attempts to solve]

However, it is conceivable that a user may mistakenly start supplying high-temperature fluid when there is no bath water in the bathtub or when the bathtub water has not reached the standard bathtub water level. Conventional methods do not have specifications to deal with such situations, and the high-temperature fluid may be splashed into the air or come into contact with the human body when it is not sufficiently mixed with the bath water, resulting in accidents such as burns. There was a risk of causing

The purpose of the present invention is to ensure high safety through rational improvements while avoiding complication of the structure around the bathtub as much as possible.

[Means for solving problems]

The characteristic configuration of the bath device according to the present invention is that a detection end of a water level detector for detecting the water level of the bathtub is attached to a high-temperature fluid ejector attached to the bathtub wall below the standard bathtub water level. A safety control mechanism is provided that automatically prevents the supply of high temperature fluid from the high temperature fluid source to the high temperature fluid ejector when the water level is lower than the standard bath water level,
Its effects are as follows.

[Effect]

In other words, even if the user mistakenly starts high-temperature fluid supply when there is no bath water or when the bath water is lower than the standard bath water level, or when the bath water is used during high-temperature fluid supply operation, Even if the bathtub water level falls below the standard bathtub water level, the safety control mechanism will automatically prevent high-temperature fluid supply based on the bathtub water level detection.
This reliably prevents the high-temperature fluid from flying into the air due to the low water level in the bathtub and from coming into contact with the human body when it is insufficiently mixed with the bathwater.

[Effect of idea]

As a result, a highly safe bathing device that can more reliably prevent accidents such as burns caused by jetting of high-temperature fluid has been created compared to conventional bathing devices.

By the way, in order to perform the above-mentioned safety control based on bathtub water level detection, it is possible to attach the detection end of the water level detector to the bathtub separately from the high-temperature fluid ejector. The structure around the bathtub becomes complicated.

In this regard, according to the configuration of the present invention, the detection end of the water level detector is attached to the high-temperature fluid ejector, so that the only attachment to the bathtub appears to be the same high-temperature fluid ejector as before, maintaining the simplicity of the area around the bathtub.Furthermore, the detection end of the water level detector and the high-temperature fluid ejector can be handled as a single item as assembly parts, which has the advantage of making on-site construction easier.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

In FIG. 1, 2 is a steam blower attached to the side wall 20 of the bathtub B, and its specific structure is as follows:
A substrate 3 is attached to the inner surface of the side wall around the hole 21 formed in the bathtub side wall 20, and a bathtub B is placed opposite the substrate 3.
The cover 4 is connected to a screw or the like using a fixture 5 to sandwich the cylindrical filtration member 1 made of sintered metal or the like between them, and the inside of the filtration member 1 is inserted through the side wall hole 21. A presser 7 connected to a steam jet pipe 8 facing the bathtub and the base plate 3 are connected with a fixture 9 such as a screw with a bathtub side wall 20 inserted between them.

Gaskets 6 are applied to both ends of the filter member 1. Further, a packing 10 having a U-shaped cross section is fitted onto the periphery of the side wall hole 21 to be clamped by the presser 7 and the substrate 3.

Holder 7 which is the outside part of the bathtub of the steam jetter 2
A water level detector 11 is installed above the top end of the filter member 1.

This water level detector 11 is constructed using a pressure switch, and its concrete structure includes a case 12.
A diaphragm 14 with a magnet 13 is stretched therein, and a contact portion 15 is attached to the case 12 which is closed when the magnet 13 approaches.

As shown in FIG. 2, the connecting cylinder part 12a of the case 12 communicating with the diaphragm chamber is attached to the protruding cylinder part 7a formed on the presser 7 with a seal ring 16.
A communication hole inside and outside the bathtub is fixed to the base plate 3 in a watertightly fitted state with screws 17, and the bathtub water is guided to the diaphragm 14, which is the pressure receiving end of the pressure switch, through the side wall hole 21 and the connecting cylindrical part 12a. 18 is formed to face the protruding cylindrical portion 7a of the presser 7, and when the bathtub water is higher than the standard bathtub water level set higher than the communication hole 18, the water pressure introduced from the communication hole 18 (i.e. , hydrostatic head pressure of bath water) to close the contact portion 15.

On the other hand, A is a steam generation source that supplies steam for heating bathtub water to the steam jetter 2 via a steam supply pipe 25, and is equipped with a burner 23 and a heat exchanger 24.

In the steam generation source A, 28 is a thermocouple that is heated by a pilot burner 27 to generate electric power, and 22 is a safety valve installed in the gas supply pipe 26.

The safety valve 22 is maintained in an open state by the electric power generated by the thermocouple 28 only when the pilot burner 27 is in a proper combustion state. That is, when blowout or incomplete combustion occurs, the safety valve 22 is closed due to a decrease in the power generated by the thermocouple 28, and the gas supply is automatically cut off.

29 is a water governor attached to the water supply system for the heat exchanger 24, and 30 is linked to the water governor 29 to allow gas supply to the burner 23 only when the water supply state to the heat exchanger 24 is appropriate. It is a water pressure responsive gas valve. That is, heat exchanger 2
Gas supply is also automatically cut off when the supply water pressure to 4 is abnormally reduced.

The pressure switch as the water level detector 11 mentioned above is
It is connected to the thermocouple safety valve mechanism as described above in the steam generation source A, and specifically, the contact part 15 of the pressure switch is connected to the thermocouple 28 for the safety valve 22.
It is interposed in the power supply circuit from.

In other words, when the steam supplied from the steam generation source A is blown into the bathtub water from the steam jet 2 to boil the bathtub water, when the bathtub water is above the standard bathtub water level, the pressure switch contact section 15 is closed to generate thermoelectric power. The safety valve 22 is held open by the generated electric power, thereby allowing the steam generation source A to operate to generate steam. However, when the bathtub water is less than the standard bathtub water level, the safety valve 22 is opened by opening the pressure switch contact 15. By shutting off the steam generator and disabling the steam generation operation, the steam jet from the steam jet device 2 is stopped, thereby preventing accidents such as burns caused by steam jets when the water level in the bathtub is insufficient. be.

[Another example]

In the above-mentioned embodiment, the steam generation source A is used as a safety control mechanism that automatically prevents the steam supply from the steam generation source A to the steam ejector 2 when the water level detected by the water level detector 11 is lower than the standard bathtub water level. Although a thermocouple safety valve mechanism was used in the present invention, as shown in FIG. A safety control mechanism may also be configured. In addition, in Figure 3,
Three types of electromagnetic safety valves 22' are installed at branch pipes for supplying hot water to showers, showers, etc.

As the water level detector 11, an electrode type sensor may be used instead of a pressure switch.

As the bathtub water heating fluid to be ejected into the bathtub water, fluids in various phase forms can be used, such as steam, hot water, and a mixed fluid of steam and hot water, which are collectively referred to as high-temperature fluids.
