Abstract

PURPOSE:To prevent the sound generated by a float that floats by the pressure of flowing water by providing a sound proofing member between the inner surface of the float and the outer surface of a guide part. CONSTITUTION:A guide part 40 extended toward above the inflow port 21 of a tank and a switch member 41 for generating flowing water detection signals are provided at a main body 37 installed in the tank for reserving flowing water. A tubular float 44 that floats by the pressure of the flowing water from the inflow port and generates flowing water detection signals is fitted at the guide part 40 in the vertically movable state. A sound proofing member 46 is interposed between the inner surface of the float 44 and the outer surface of the guide part 40. Accordingly, the contact sound between the float 44 and the guide part 40 can be efficiently prevented by means of the sound proofing member 46.

By the way, warm water (1
The flow in step 9) is detected by a water flow detector (20) installed in the cistern tank (17). That is, as shown in FIG.
When warm water (19) flows into the interior, the warm water (19)
Flows 1 to (44) are floated along the guide cylinder (40) by the jet pressure of
In step 5), the reed switch (41) in the guide tube (40) is turned on to generate a flowing water detection signal. Then, in response to this flowing water detection signal, the combustion tube (6) of the combustor (5) is activated, and the heating operation described above is continued.

When the float (44) floats to turn on the reed switch (41), the float (44) vibrates above the guide portion (40) due to pulsation of the hot water (19) or the like. However, since the tube-shaped soundproofing member (46) made of a flexible material is attached to the outer surface of the guide part (40), a "con-con" contact sound between the float (44> and the guide part (40)) is generated. can be prevented from occurring.

On the other hand, if the circulation pump (22) stops abnormally due to a malfunction, etc.
Alternatively, if the flow of the hot water (19) is blocked in the middle of the piping for some reason and the pressure of the hot water (19) at the inlet (21) of the distillation tank (17) decreases, the specific gravity may become less than 1. The large float (44) sinks onto the lower stopper (43) due to its own weight, and the reed switch (41)
is turned off, and the operation of the combustion tube (6) is stopped. Therefore, it is possible to prevent abnormal heating of various devices due to abnormal stoppage of the circulation pump (22) or the like.

Therefore, according to the above embodiment, the running water detector (20)
can be installed inside the cistern tank (17), simplifying the piping connection configuration of the hot water hot air heater, and eliminating the need for storage space for the flowing water detector (20) in the piping space. It can contribute to the miniaturization of the product shape of water hot air heaters. Moreover, although the structure is such that the flow of warm water (19) is detected by movement of the hot water (19) to flow 1 (44) in the distern tank (17), the soundproofing member (4)
6), the contact sound between the float (44) and the guide part (40);
And the resonance sound of the distern tank (17) caused by this can be efficiently prevented.

By the way, in the above embodiment, a reed switch (41) was used as the switch member, but when implementing the present invention, the present invention is not limited to this, and a float (44) such as a limit switch or a proximity switch may be used. Various switches can be used that have the function of generating a flowing water detection signal when the robot ascends to the surface.

[Effects of the Invention] As described above, the running water detection device of the present invention includes a main body installed in a tank that stores running water, a guide section that extends vertically above the inlet of the tank, and a running water detection signal that generates a running water detection signal. a switch member is provided, and a cylindrical float having a specific gravity greater than 1 is vertically movably fitted on the guide portion and floats under the pressure of the flowing water from the inlet to generate a flowing water detection signal from the switch member; Since it is necessary to install a soundproofing material between the inner surface of the float and the outer surface of the guide part to prevent contact noise from both sides, a flowing water detector is installed inside the tank to simplify the piping connection configuration. In addition to eliminating the need for a storage space for a flowing water detector in the piping space, it contributes to a more compact product, and the soundproofing material effectively prevents contact noise between the float and the guide section. .
