Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water purifying and circulating apparatus which can automatically improve high-speed operation and low-speed operation by selecting a mode with a single pump and remarkably improve sterilization efficiency.

[0002]

2. Description of the Related Art Conventionally, in a bath water purifying and circulating apparatus for bathing for 24 hours, hot water (bath water) is always ready for bathing at an appropriate temperature. In addition, it should be bath water from which scales have been removed. Further, the bath water needs to be sanitized from the viewpoint of hygiene. In addition, in the bath water purifying circulation device, in general, a jet jet or the like is generally provided at the circulating outlet or the like so as to stimulate the body.

[0003]

In the case of a circulation pipe provided with a jet jet, the flow velocity is too high and it is not suitable for giving a sterilizing action to bath water. That is, it is necessary that the sterilizing action of the sterilizing device with respect to the bath water sufficiently functions, and therefore, it is demanded that the sterilizing action with respect to the bath water sufficiently functions with a simple device. .

[0004]

Therefore, as a result of intensive studies, the inventor of the present invention has found that the present invention can be applied to a heating means for heating bath water and a bath for removing impurities that become fine dust and dirt. A filter for filtering from water, a sterilizer for sterilizing bath water, a circulation pump for circulating the bath water,
A circulation pipeline through which bath water circulates with the circulation pump, and a sterilization pipeline that passes through the sterilization device branched from the circulation pipeline,
Pump control means for controlling the operating speed for at least the high speed operation and the low speed operation of the flow rate of the circulation pump; and a mode selecting means for switching the operating speed with the high speed operation as a bathing mode and the low speed operation as a sterilization mode. A pump is constituted by a mode display means for displaying the mode, and a bath water purifying circulation device in which bath water having a flow velocity corresponding to the mode is divided into a circulation pipe and a sterilization pipe. Thus, the high-speed operation and the low-speed operation can be performed, and the sterilization efficiency can be remarkably improved, and the above-mentioned problems are solved.

[0005]

According to the present invention, when bathing, the bathing mode is set as a bathing mode, the flow velocity of the bath water purifying circulation device can be increased, and the jet jet effect can be obtained. In this case, the flow velocity becomes slow, and the bactericidal action on the bath water can be sufficiently made to function.

Next, description will be made with reference to the flowchart shown in FIG. First, it is determined whether or not the bathing mode 22a is selected (see S1). When the bathing mode 22a is selected, the bathing mode 22a is set (see S2), and the mode display means 23 displays the bathing mode 22a. (See S3). Then, the circulation pump 8 operates at high speed S

As the sterilization device A, there are an ozone generator 3, ozone water injection means 4, ultraviolet sterilization means 5, chlorine agent addition means 6, electrolysis means 7 and the like. The ozone generator 3 is composed of an ozonizer section 3a and an ozone mixing section 3b for mixing ozone (see FIGS. 1 and 5). The ozone water injecting means 4 is composed of an ozone water generating section 4a and a tank section 4b for injecting and storing ozone water into the sterilization pipeline 10 (see FIG. 8).

In addition, the chlorine agent adding means 6 needs to be sterilized by chlorine, and the amount must be limited because it does not affect the human body in addition to the required amount.

The electrolyzing means 7 also has a bactericidal action. During electrolysis, the bacterial cells are damaged by the direct or indirect action of the electrodes, leading to fatal cell destruction. The lethal damage of bacteria due to the direct action of the electrode occurs when bacterial cells are oxidized or reduced on the surface of the electrode, but the frequency of contact with the electrode is low, and therefore the contribution of sterilization is small. In addition, lethal damage of bacteria due to the indirect action of electrodes occurs through the redox reaction of components other than bacterial cells such as ions, solvents and dissolved gases in the electrolytic solution,
In the sterilization by the electrolysis means 7, the indirect action is generally larger than the direct action.

There is also one that is provided in series with the device A and in the middle of the sterilization line 10. In the case where the filter 2 is provided in the sterilization pipe line 10, the flow rate is limited for sterilization.
In particular, reducing the flow velocity of the filter 2 is effective in preventing clogging of the filter 2 or increasing the filtration efficiency of the filter 2.

An ultraviolet ray sterilizing means 5 may be provided in the middle of the sterilizing line 10 of the ozone generator 3 of FIG. 5 or the ozone water injecting means 4 of FIG. This figure is indicated by a chain double-dashed line in FIGS. By providing the ultraviolet sterilization means 5 in this way, it is possible to further increase the types of cells that cause lethal damage and improve the sterilization efficiency.

Further, as shown in FIG. 12, any one of the ozone generator 3, ozone water injection means 4, and ultraviolet sterilization means 5 is used.
In a configuration in which one is provided in the sterilization pipeline 10, the sterilization pipeline 10 may be provided with the chlorine agent adding means 6. As described above, by increasing the chlorine sterilization efficiency in addition to ozone and ultraviolet sterilization, it is possible to further increase the types of cells that cause lethal damage and improve the sterilization efficiency.

Further, as shown in FIG. 13, any one of the ozone generator 3, ozone water injection means 4, and ultraviolet sterilization means 5 is used.
In a configuration in which one is provided in the sterilization pipeline 10, the sterilization pipeline 10 may be provided with the electrolyzing means 7. In this way, by increasing the sterilization efficiency by the electrolysis action in addition to ozone and ultraviolet sterilization, it is possible to further increase the types of cells that cause lethal damage and improve the sterilization efficiency.
