Description

  The present invention relates to an apparatus for producing electrolytic reduced water for bath water that generates electrolytic reduced water having a reduced redox potential by electrolyzing the bath water.

  Conventionally, the utility of reduced water in which the redox potential (hereinafter referred to as ORP) is reduced by electrolyzing water has attracted attention in various fields. Reduced water with a low ORP value has high osmotic pressure and becomes tasty, and is a major cause of many diseases and aging such as cancer, diabetes, arteriosclerosis, hepatitis, atopic dermatitis, and brain dysfunction. It is known that it has the function of giving electrons to and reducing them. Therefore, Japanese Patent Application Laid-Open No. 2004-122108 (Patent Document 1) conventionally shows that water is electrolyzed to produce electrolytic reduced water and used for beverages.

  Furthermore, in recent years, it has been proposed to use reduced water having a reduced ORP value as bathtub water as well as drinking water. Since normal tap water is sterilized with chlorine as a safety measure, the ORP value is high, which has the adverse effect of oxidizing the skin. On the other hand, it has been empirically shown that reduced water having a reduced ORP value has a cleaning effect or a moisturizing effect on the skin.

  As a conventional example of such a reducing water generating apparatus for bath water, for example, one described in Japanese Patent Application Laid-Open No. 2004-202429 (Patent Document 2) is known. FIG. 6 is a flow diagram showing the configuration of the reducing water generator for bath water described in Patent Document 2. As shown in FIG. 6, the filter 107 is put in the bath water 111 stored in the bathtub 109. Further, the pump 103, the electrolytic cell 101, and the flow sensor 105 are connected to the filter 107 via a pipe, and the discharge side of the flow sensor 105 is introduced into the bathtub 109.

When the electrolytic bath 101 is energized and the pump 103 is driven to circulate the bath water 111, the bath water introduced into the electrolytic bath 101 is electrolyzed, and the reduced water obtained by electrolysis is obtained. Is returned into the bathtub 109 via the flow sensor 105. Therefore, the ORP value of the bath water 111 in the bathtub 109 can be reduced.

  Further, as shown in FIG. 2, a waterproof urethane material (floating means, waterproofing) is provided at a level (a level near the joint between the lid 3 and the body 2) at a predetermined height from the upper end in the housing. Member) 19 is filled so as to fill in the lateral direction, and a space is formed in the casing on the upper side of the urethane material 19. That is, it is configured such that water does not enter this space when the casing is floated in bath water. Further, exhaust holes 20 are formed at a plurality of locations near the upper end of the body portion 2.

  The pump 5 has a waterproof structure as a whole, pumps up bath water from an introduction pipe 8 disposed below the surface of the bath water, and supplies it to the electrolytic cell 6 through a connecting pipe 13 shown in FIG. .

  The electrolytic bath 6 has a waterproof structure as a whole, electrolyzes the bath water supplied from the pump 5 to generate electrolytic reduced water, and the generated electrolytic reduced water is bathed through the discharge pipe 9. Drain in.

  In addition, a small hole 10 is formed at the top of the lid 3, and an electric wire 11 connected to the pump 5 and an electric wire 12 connected to the electrolytic cell 6 are connected to the outside through the small hole 10. Has been derived. Therefore, the electric power for driving can be supplied to the pump 5 and the electrolytic cell 6 by connecting the electric wires 11 and 12 to a power supply device (not shown).

  FIG. 3 is an explanatory diagram showing a connection relationship between the electrolytic cell 6 and the pump 5 and a structure in which the electrolytic cell 6 is disassembled. As shown in the figure, the lower part of the pump 5 and the lower part of the peripheral frame 6a of the electrolytic cell 6 are connected by a cylindrical connecting pipe 13, and the bath water pumped up by the pump 5 is put into the electrolytic cell 6. Supply. In addition, an opening 6b is formed at the center of the upper surface of the peripheral frame 6a of the electrolytic cell 6.

  Further, inside the peripheral frame 6a, a plurality of (seven in the figure) electrodes 14 and a long bottom fixing that fixes the respective electrodes 14 substantially in parallel and equidistantly below the peripheral frame 6a. A member 15, an upper fixing member 16 for fixing each electrode 14 above the inside of the peripheral frame 6a, and a square-shaped spacer member 17 that provides a space between the upper fixing member 16 and the upper surface of the peripheral frame 6a. I have.

  Each of the seven electrodes 14 has a rectangular shape with protrusions 14a and 14b formed on the upper part, and each electrode 14 is spaced substantially parallel and equidistantly so that the protrusions 14a and 14b are alternately positioned on the left and right. Are lined up. The lower end portion of each electrode 14 is attached to a groove portion 15 a formed on the lower fixing member 15, and the protruding pieces 14 a and 14 b serving as the upper end portion are attached to the groove portion 16 a formed on the upper fixing member 16. . A DC voltage supplied from a power supply device (not shown) is applied between the left three protrusions 14a and the right four protrusions 14b.

  A circular opening 18 is formed at the center of the upper fixing member 16. Accordingly, the bath water supplied into the electrolytic cell 6 through the connection pipe 13 passes between the plurality of electrodes 14 and then is introduced into the discharge pipe 9 (see FIG. 1) through the opening 18 and the opening 6b. It is burned.

  Next, the operation of the electrolytically reduced water generator 1 of the present embodiment configured as described above will be described. As described above, when the electrolytically reduced water generating apparatus 1 is put into bath water, the bath water enters the housing from the opening 4a formed in the bottom plate 4. At this time, the air existing between the bottom plate 4 and the urethane material 19 is discharged to the outside from the exhaust hole 20 formed in the body portion 2. Further, bath water cannot enter above the urethane material 19, so that buoyancy is generated by the urethane material 19 and the space formed above the urethane material 19, and the entire apparatus is suspended in the bath water. Become.

  In this state, when the pump 5 is driven and a voltage is applied to the electrode 14 in the electrolytic cell 6, bath water is pumped from the bath and introduced into the electrolytic cell 6, so that the introduced bath water is It passes between the electrodes 14 to which a voltage is applied, and electrolysis is performed. As a result, electrolytic reduced water having a reduced ORP value can be generated, and the generated electrolytic reduced water is discharged into the bathtub through the discharge pipe 9.

  That is, the bath water stored in the bath is introduced into the electrolytic cell 6 at a predetermined flow rate, is electrolyzed and returned to the bath, and the ORP value of the entire bath water can be reduced.

  Next, a change in the ORP value (redox potential [mV]) when bath water is electrolyzed using the electrolytic reduced water generator 1 according to the present embodiment will be described. FIG. 4 is a characteristic diagram showing the relationship between the operating time and the change in the ORP value of the bath water when electrolysis is performed using the electrolytic reduced water generator 1 according to the present embodiment. This characteristic diagram is data when 200 [liter] of tap water accumulated in the bathtub is heated to 42 ° C. and electrolyzed at a treatment rate of 10 [liter / min].

  As shown in the figure, the ORP value of the bath water initially stored in the bathtub is about 460 [mV], whereas the ORP value decreases as the electrolysis time elapses. Is understood. For example, by operating for 40 minutes, the ORP value becomes a negative potential.

  Thus, the electrolytically reduced water generating apparatus 1 according to the present embodiment drives the pump 5 and applies a voltage to the electrode 14 of the electrolytic cell 6 while floating in the bath water stored in the bathtub. By passing the bath water through the electrolytic cell 6, it is possible to generate electrolytic reduced water having a gradually reduced ORP value. Thereby, since the ORP value of the bath water as a whole can be lowered, it is possible to obtain an effect such as a cleaning effect or moisture on the skin.

  In addition, since the entire device is driven while floating in the bath water, the installation space for the device is not required and the installation space is secured in the vicinity of the bathtub like a unit bath. Even if it is impossible, it can be used easily.

  Furthermore, since it is the structure used by making it float in bath water, it can carry, it can be used without being fixed to one bathtub, and a use purpose can be expanded. In addition, installation work for installing the device in a predetermined installation space is not required.

  In addition, the length of the intake pipe and drain pipe can be shortened as a whole compared to the installation-type electrolytic reduction water generator described in the conventional example, so the path from intake to drain is shortened. And the amount of heat radiation can be reduced. Moreover, the electric power required for driving the pump 5 can be reduced.

  Next, a modified example of the present invention will be described. FIG. 5 is an explanatory view schematically showing the configuration of the electrolytic reduced water generating apparatus 1 according to the modification. As shown in the figure, this electrolytic reduced water generator 1 is a movable nozzle capable of changing the inclination angle at the tip of a discharge pipe 9 for discharging reduced water electrolyzed in an electrolytic cell 6. 21 is provided. When the movable nozzle 21 is inclined at a predetermined angle with respect to the discharge pipe 9, the entire apparatus moves in a circular shape in the bathtub due to the flow of the reduced water discharged. Accordingly, the bath water can be taken in while stirring the entire bath water, and the entire bath water can be uniformly electrolyzed.

  As mentioned above, although the electrolytic-reduction-water production | generation apparatus for the water for baths of this invention was demonstrated based on embodiment of illustration, this invention is not limited to this, The structure of each part is the arbitrary which has the same function. It can be replaced with a configuration one.

  For example, in the above-described embodiment, the example using the waterproof urethane material 19 as the floating means has been described. However, the present invention is not limited to this, and the material can be floated in the bath water. I just need it.

  Moreover, although the structure used in the state which floated the whole apparatus which concerns on this embodiment in the bathtub was demonstrated, attaching the wire for fixation to an apparatus, connecting this wire to the hook attached around the bathtub etc., etc. It can also be set as the structure which fixes an apparatus to the predetermined position in a bathtub. With such a configuration, the apparatus does not move unnecessarily in the bathtub, and the apparatus can be operated during bathing.

  Even when there is no installation space, it is very useful for easily floating on the bath water in the bathtub and electrolyzing the bath water to produce electrolytic reduced water.
