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 circulation device which can improve the sterilization efficiency by a single pump, even if the operating speed is constant, by slowing the flow velocity in the sterilizing pipe. .

[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 pipe in which bath water circulates in the circulation pump, and a sterilization pipe that passes through the sterilization device branched from the circulation pipe, and the cross section of the sterilization pipe is larger than the cross section of the circulation pipe. By making the bath water purifying and circulating device to be large, even if the operating speed is constant with one pump, the flow velocity can be slowed in the sterilization pipeline to improve the sterilization efficiency, This is a solution to the above problems.

[0005]

According to the present invention, even when bathing, in the sterilization mode, and while maintaining a constant flow rate by the circulation pump, the flow rate is slowed in the sterilization pipe line, and the sterilization action can be performed on the bath water. it can.

[0006]

Embodiments of the present invention will be described below with reference to FIGS.
1 will be described. As shown in FIG. 1, the bath water purifying and circulating apparatus mainly comprises a heating means 1 for heating the bath water, a filter 2 for filtering fine dust and impurities from the bath water. It is composed of a sterilizer A for sterilizing bath water, a circulation pump 8 for circulating the bath water, and the like.

The filter 2 is, as a kind, a precision filter or an ordinary filter, which is used as an adsorbent filter medium filter material filled with activated stone or activated carbon, or is made of a woven or non-woven fabric and made of a filter material. There is also something to configure. In any case, fine dust and dirt that are impurities are removed.

The circulation pump 8 is composed of one unit, and its operating speed is set to a predetermined rotation. Also,
The circulation line 9 is provided with a sterilization line 10 branched from the middle of the circulation line 9. The circulation line 9 is configured to communicate with at least the heating means 1, and the circulation pump 8 is provided at an intermediate position thereof.
A pre-filter 11 is provided on the suction side of the circulation line 9, and a jet portion 12 is provided at the discharge port thereof so as to be directly connected to the bath 13 and to generate a jet jet.

There are two types of embodiments of the sterilization pipeline 10, and the first embodiment thereof is shown in FIGS. 1, 2, 4, and 6.
As shown in FIG. 11, a bypass-shaped sterilization pipeline 10 is provided in the circulation pipeline 9. Specifically, the sterilization pipeline 10 is provided by branching from the middle of the circulation pipeline 9. Further, the rear end of the sterilization conduit 10 is connected to the circulation conduit 9 again and configured to return.

As shown in FIGS. 3 and 5, the second embodiment of the sterilization pipeline 10 has the same attachment point on the front end side as the first embodiment, but the rear end side is the same as the circulation pipeline 9. Are configured to face the bathtub 13 independently. In any case, the diameter of the sterilization pipeline 10 is larger than the diameter of the circulation pipeline 9. Since the increase of the flow rate is in inverse proportion to the increase of the cross-sectional area, the flow velocity to the sterilization pipeline 10 is configured to be slower than the flow velocity of the circulation pipeline 9.

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 includes an ozonizer section 3a and an ozone mixing section 3b for mixing ozone (see FIGS. 1 and 3). 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 in the sterilization pipeline 10 (see FIG. 6).
The ultraviolet ray sterilization means 5 is provided with an ultraviolet ray lamp 5a inside the case, and the bath water passes through while being irradiated with the ultraviolet ray lamp 5a (see FIGS. 2 and 7).
Further, the chlorine agent adding means 6 is composed of a chlorine agent adding section 6a and a tank 6b for adding a chlorine agent and mixing it with bath water (see FIG. 8). Further, the electrolysis means 7 includes an anode 7b and a cathode 7c in a tank 7a provided in the sterilization pipeline 10.
And a DC power supply 7d is applied to this (see FIG. 9). Such a sterilizing apparatus A always maintains an operating state regardless of whether or not it is during bathing.

In the sterilization apparatus A, the ozone generator 3 and the ozone water injection means 4 are sterilization means by ozone, and the ozone generator 3 has a high sterilization efficiency, but the problem of noise is also a problem. The water injection means 4 solves the noise problem. Further, the ultraviolet sterilization means 5 is silent, and the issue of sterilization efficiency is an issue. 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.

The filter 2 is provided in the middle of the circulation line 9 as shown in FIGS. 1 to 3, or the filter 2 is provided with the sterilizer A as shown in FIGS.
There is also one that is provided in series with the sterilization pipeline 10 in the middle thereof. In the case where the filter 2 is provided in the sterilization pipe line 10, since the flow rate is limited for sterilization, it is possible to particularly reduce the flow rate of the filter 2 and prevent clogging of the filter 2, or It is effective in 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. 3 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.

As shown in FIG. 10, 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. 11, 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.

According to the invention of claim 4, the ultraviolet light sterilizing means 5 is used as the sterilizing apparatus A.
In particular, in the sterilization mode 22b, there is an advantage that the flow velocity becomes low, the probability that the bath water is irradiated with ultraviolet rays increases, and the sterilization efficiency can be further improved.

In the invention of claim 5, the sterilizer A is the chlorine agent adding means 6, so that the effect of claim 1 can be obtained.
Although it is necessary to adjust the amount of the chlorine agent added, this is when the flow velocity is reduced, and the chlorine agent can be satisfactorily added to contribute to the increase in sterilization efficiency.

According to the sixth aspect of the invention, since the sterilizing apparatus A is the electrolyzing means 7, in addition to the effect of the first aspect, the solution to be sterilized is bath water, which is not in a stationary state and the flow velocity is low. In some cases, although not necessarily efficient, the direct or indirect action of the electrolysis action has a bactericidal effect.
