Description

[Detailed Description of the Invention] [Industrial field of application] The present invention connects a bathtub and a heat exchanger for reheating through a circulation reheating circuit, and circulates the hot water in the bathtub to reheat it. The present invention relates to a bathtub hot water temperature detection device for a bath device, which is to be reheated by a heat exchanger for use in a bathtub.

[Conventional technology]

The simplest bath apparatus as described above is constructed as shown in FIG. 4, and is constructed so as to reheat the set temperature as shown in FIG. That is, in FIG. 4, 1 is a bathtub, 1a is a bathtub circulation fitting,
A heat exchanger 3 for additional heating arranged in the circulation fitting 1a and the device 2.
Is connected via a circulation heating circuit composed of a return pipeline 4a and a forward pipeline 4b, and a pump 5 is connected to the circulation heating circuit in the device.
And a thermistor 6 for detecting the hot water temperature are provided, and when the hot water heating switch is turned on after the boiling water temperature is set on the remote controller (not shown), the pump 5 is driven to circulate the hot water in the bathtub. The thermistor 6 detects the hot water temperature, and when the detected hot water temperature does not reach the set temperature, the burner (not shown) of the additional heat exchanger 3 is ignited to perform the additional heating.
When the set temperature is reached, the reheating operation is stopped and the pump 5
I'm trying to stop. Incidentally, FIG. 4 and FIG.
Although the figure shows the simplest example, in fact, in a bath device with a water heater, set the water level and boiling water temperature to the bathtub on the remote control, and turn on the automatic operation switch, Hot water at a temperature close to the set hot water is discharged from the water heater and dropped into the bathtub, and when the water level in the bathtub reaches the set water level, pouring is automatically stopped, and then the pump is driven to start additional heating operation. It is configured to carry out a warming operation as necessary.

[Problems to be solved by the device]

According to the method shown in FIGS. 4 and 5, the hot and cold water in the bathtub can be reheated even if the bathtub 1 and the appliance 2 are separated, and the hot and cold water is circulated in the bathtub by the pump. Since it is reheated, the hot and cold water in the bathtub can be stirred and boiled to the set temperature.

However, as shown in FIG. 4, when the bath 1 and the appliance 2 are installed at a distance from each other and the thermistor 6 is arranged in the appliance 2, the circulation heating circuit acts as a heat radiating portion. , The hot water temperature T ₁ in the bathtub reaches the set hot water temperature, but the hot water temperature T ₂ detected by the thermistor 6 detects a hot water temperature lower than the heat radiation amount T ₃ minutes, and as a result, the hot water bath temperature is set. There is a problem that it will boil higher.

In order to eliminate such a temperature error, the thermistor 6 is arranged in the return pipe 4a of the circulation heating circuit close to the bathtub 1, and the signal detected by the thermistor 6 is remote-controlled by the lead wire (or the control part in the instrument). It is possible to tell

In this way, the temperature of the hot water in the bathtub can be accurately detected, but electric wiring in the bathroom is required, and this electric wiring in the bathroom is not preferable because there is a risk of leakage.

The present invention solves the problems of the prior art as described above, does not require electrical wiring work in the bathroom, and provides accurate bathtub temperature control even when the bathtub is made of metal such as stainless steel. It is an object of the present invention to provide a hot water temperature detecting device capable of detecting and transmitting and detecting the temperature and heating the set temperature.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention connects a bathtub and a heat exchanger for reheating through a circulation reheating circuit, and circulates the hot water in the bathtub by a heat exchanger for reheating. In a bath device to be reheated, a hot water temperature sensor for detecting the return hot water temperature is arranged at a position close to the bathtub of the return pipe of the circulation heating circuit, and the circulation heating circuit generates electricity by running water to generate the hot water. A power generator capable of storing electric power and a charger are provided, and the temperature signal obtained by the hot water temperature sensor is used as an electric power source by using the electric power obtained by the power generator and the charger to wirelessly install an antenna at a chain attachment portion of a bathtub drain plug. It is characterized in that the information is transmitted to the control unit.

[Action]

According to the present invention, as described above, the hot water temperature sensor for detecting the return hot water temperature is arranged at a position near the bath of the return pipe of the circulation heating circuit, and the power is stored in the circulation heating circuit by running water. A power generator and a charger are installed, and the electric power generated by the generator and the charger is used as a power source to wirelessly transmit the signal obtained by the hot water temperature sensor to the control unit, which requires electrical wiring work in the bathroom. It is possible to control the reheating by accurately detecting the bath water temperature without using the above. Furthermore, since the above-mentioned transmission is performed by providing an antenna at the chain attachment part of the bathtub drain plug, the bathtub is made of stainless steel or the like. Even if it is a metal, it is possible to reliably control the reheating without hindering the transmission.
