2. Description of the Related Art In a general home tub, a water heater is connected to the tub,
Each time heating is required, hot water is supplied by operating a water heater by burning gas or the like. In recent years, there has been a case where a device for constantly maintaining the temperature of bath water at a constant level is used, but in any type of water heater, oil or gas or an electric heater is used to dispose the device outside the bathtub. It is configured to supply hot water from a hot water heater.

However, as described above, a system in which a water heater is disposed outside a bathtub and heated as necessary is relatively poor in thermal efficiency, and compared with the energy used. However, there is a disadvantage that the efficiency of heating the hot water is not good. Further, when a water heater is arranged outside the bathtub, the size of the bathtub may be limited because the area occupied by the water heater is large. On the other hand, when the water heater is disposed outside the bathroom, a long pipe is disposed between the water heater and the bathtub, so that the heat efficiency of the water heater is further reduced.

In order to solve the above problems,
It has been practiced to use a method in which a small heating device such as a 24-hour bath is arranged near a bathtub to constantly heat the bath. In addition, a device called a 24-hour bath, which is often used in recent years, does not have a bathtub, for example, while circulating hot water in a bathtub with a water heater, removing impurities contained in the hot water through a filter or the like. The hot water is kept clean. However, a water heater as described above,
Since a pump or the like is used to circulate the hot water in the bathtub between the water heater and the water heater, the energy use efficiency is not significantly improved as compared with the conventional water heater.

The present invention solves the above-mentioned problems of the conventional water heater, and heats the hot water while circulating the hot water in the heating device in a state where the heating device is placed in the bathtub. An object of the present invention is to provide a bath tub heating device capable of easily purifying and heating hot water while releasing an effective component such as a hot spring from contained ceramic components.

In the ceramics (D) produced as described above, an inorganic material such as zeolite or vermiculite is converted into a ceramic material while retaining its porous property, and after mixing other components, the calcareous material is mixed. Since the low-temperature sintering is performed at a temperature at which the properties do not change, each mixed component can be used effectively. In addition, before being manufactured into a lump, the calcium component is changed to a property dissolvable in water by mixing the hydrogen peroxide solution, so that the calcium component can be easily eluted, and a bath rich in calcium ions.

In addition to the components to be contained, in the present invention, zeolite and vermiculite are used as the inorganic porous material, and coral sand powder and shell fossil powder can be used as the porous material rich in the calcium component. .

In addition to the above-described structure, fine powder of a strontium ferrite magnet can be used as the magnetic material, and conditions such as the strength of a magnetic field applied to the magnetic material can be arbitrarily set. In addition, each component to be mixed with the ceramics can be used in place of another component having similar properties. Further, the ceramics for water treatment of the present invention can be configured as a pipe, a ball, a flat or medium-high circular mass, or any other shape. It is preferable that the maximum size is about half the diameter of the heating conduit. In addition, when considering the reduction of the ceramic mass to soil after use, the ceramic mass is configured as a relatively small mass, and the microorganisms and active ingredients and the component adsorbed on the ceramic mass are mixed directly into the ground. Thus, it can be reused as a growth substrate for microorganisms in a field or the like.
