It is mainly composed of a heater for keeping the temperature at a desired temperature, and further has a hose for connecting the main body and the bath, a control panel for setting the temperature of bath water, a temperature sensor, etc. . With the above structure, the circulating hot bath machine is capable of purifying the bath water by circulating the bath water inside the main body and controlling the temperature of the bath water so as to obtain a desired temperature.

On the other hand, as a method for purifying the bath water, generally, activated carbon or ore is used, which is mixed with the bath water to remove pollutant particles, and biological purification using aerobic bacteria. A purification method that combines and is used. Here, biological purification uses a septic tank composed of porous ceramics in which aerobic bacteria are propagated, and by circulating bath water in the septic tank, bacteria decompose the pollutants dissolved in the bath water. It is a method of purifying by doing. In addition, as another method, rough stones that generate mineral components are used, organic substances are precipitated and aggregated by the eluted mineral components, and purified by filtering in a septic tank composed of a porous material such as ceramics. There is a way to do it. However, in this method, the amount of minerals extracted from a fixed amount of rough stones is very small, so that the device itself for extracting minerals requires a very large volume. In order to solve this point, there is a device configured by using a purification solution in which a mineral component is extracted from a natural mineral. This is a method of precipitating and aggregating organic substances by mixing a certain amount of the same mineral solution into bath water, and the device for eluting the mineral components described above can be downsized.

It was necessary to regularly clean the inside of the pipes such as the pipes that guide the water so that various bacteria do not propagate.

Further, a mineral group solution containing a high concentration of various kinds of metal ions is injected into bath water to precipitate organic substances.
Even in the conventional method of purifying by aggregating and filtering this in a septic tank made of a porous material such as ceramic, periodic cleaning or replacement of the septic tank and cleaning of the septic tank container are required as in the above-mentioned biological purification method. Met. Then, in order to save the user's trouble as much as possible, a device for performing backflow cleaning, in which the normal flow direction of the bath water is backflowed to clean the inside of the hose and the piping, is required.

As described above, both types require maintenance of piping and the like, which is very troublesome for the user. In addition, special control and equipment were required for backwashing.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a circulating hot bath which has a simple structure and does not require troublesome maintenance such as cleaning of piping.

Then, in the mixing section 9 to be described later, the cleaning solution added from the adding section 3 is configured to be supplied from the tank 5.

The tank 5 is constructed so that the cleaning solution transferred from a container for storing the cleaning solution (not shown) can be temporarily stored before use by removing the lid 24 provided on the upper portion thereof. There is. Further, a pipe 26, which is a path for mixing the cleaning solution into the bath water, is connected to the bottom of the tank 5. A pump 7 for pumping a predetermined amount of the cleaning solution from the tank 5 and supplying it to the adding unit 3 described later is installed below the pipe 26. The pump 7 is driven by a signal from a control device (not shown) for a certain period of time to pump out a predetermined amount of the purified solution from the tank 5 and supply it to the addition section 3. The purification solution pumped out from the pump 7 is added and mixed with the bath water in the addition section 3 via a pipe 27 connected between the lower portion of the pump 7 and the addition section 3. Further, the pipe 27 is configured such that the upper end thereof can be fitted into a through hole 80 formed in the middle of a pipe 25 connected to a heating device 8 described later and reach the suction port 10 through the inside of the pipe 25 and the inside of the pipe 18.

Since the coagulant for water treatment precipitation described in JP-A-2003-304 is applied to bath water, the description thereof will be omitted. However, the water treatment precipitation coagulant is an organic substance that is invisiblely dissolved in bath water. Has the action of precipitating and agglomerating to form flocs. And the flocked organic matter is
The size is easily removable. Therefore, by mixing the water treatment precipitation flocculant with the bath water, the organic matter dissolved in the bath water, which was conventionally impossible to remove with the ordinary filter agent, is flocculated, and the flocculated organic matter is filtered by the below-mentioned method. Part of the filtering agent allows the removal. Also,
Since the concentration of the purification solution in the bath water immediately after being added and mixed is higher than the concentration of the purification solution in the bath water in the bath 55, the flow passage pipes existing in the addition section 3 and thereafter, such as the pipe 25 and the pipe described later, are used. 23, the aforementioned water pipe 19
