Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an electrolyzed water generating device that electrolyzes water to produce alkaline ionized water and acidic water. The present invention relates to a water intake piping system for a pressure-type electrolyzed water generator that continuously generates electrolyzed water by converting the polarity of an applied voltage.

[Technical Background of the Invention] Normal operation of devices that electrolyze water to produce alkaline ionized water and acidic water is impaired due to calcium deposits in the cathode chamber of the electrolytic cell and in the alkaline water piping. For this reason, precipitated calcium is dissolved by periodically performing chemical cleaning and reverse electric cleaning.

However, chemical cleaning and reverse electric cleaning not only require a cleaning water circuit, but also require specialized skills for cleaning operations, making maintenance difficult. Also, during the cleaning process?
There is also the disadvantage that the generation of ice melt is stopped. Therefore, an electrolytic water conditioning device has been proposed that uses an electrode that can be used as both a cathode and an anode, and that can continuously generate electrolyzed water by changing the polarity of the applied voltage at predetermined intervals.

In this type of electrolyzed water generation device, the electrode chamber and the electrolyzed water pipeline are periodically switched from alkaline water to acidic water, so precipitated calcium is washed away, but water is supplied from one side of the electrolytic tank, Various inconveniences occur in so-called pressure-type electrolyzed water generators in which the water supply and the operation of the electrolyzer are controlled by a valve submerged in the other side of the electrolyzed water intake pipe.

First of all, what about this scale's pressure-type electrolyzed water generator? U To control the supply of water to the electrolytic cell on the electrolyzed water usage side, that is, on the water intake side, it is necessary to open and close the pair of intake channels of the electrolytic cell at the same time. If this is not done, the open intake channel will become a drip and the water supply will not be able to be stopped.

Therefore, in the past, the electrolyzer was turned on and off by detecting the flow rate of one pipe that was opened and closed by a faucet, etc.
” It is controlled by F and opens and closes in conjunction with this.

[Problem to be solved by the invention]

By the way, conventionally, a two-stage flow switch valve was installed downstream of the flow switching device of a pair of water intake pipes, so the water flowing through the pair of passages of the flow switch valve was specified to be alkaline water or acidic water. . Therefore, even if the electrical properties change, the calcium in the alkaline water passage of the flow switch valve is not dissolved, and in the end, the entire device has to be cleaned with a chemical solution in order to clean the flow switch valve.

In addition, even if you simply change the flow switch valve to the upstream side of the flow path switching device, the water intake faucet and the flow detection path of the flow switch valve will no longer correspond to each other due to the flow path switching device.
The water supply cannot be turned off (and the problem remains unsolved).

Therefore, the main object of the present invention is to provide an electrolyzed water generating device in which precipitated calcium in a flow switch valve is also removed at the same time, and a pair of intake channels are opened and closed in communication with each other by opening and closing the water intake snake [1]. The goal is to make it completely unnecessary.

Another object of the present invention is to drain water from the water intake pipe for a predetermined period of time when switching the polarity of the 7U electrolysis voltage, and to prevent water of the other nature from mixing with alkaline water or acidic water on the water intake side at the time of switching. The purpose of the present invention is to provide a water generating device.

[Means for Solving the Problems] The above-mentioned object of the present invention is to provide a pressure-type electrolytic cell that uses a cathode-anode electrode and continuously decomposes water by changing the polarity of the applied voltage. At the same time, in the electrolyzed water generation device, a flow path switching device is provided in the pair of electrolyzed water intake pipes of the electrolytic cell, so that the polarity conversion of the electrode and the flow path switching of the intake channel are operated in conjunction with each other. It has two systems of fluid passages, a flow rate detection passage and a flow passage opening/closing passage, and detects the current in the detection passage to control the electrolysis operation of the electrolyzer on and off, and in conjunction with this, controls the opening and closing of the opening/closing passage. One two-stage flow switch valve is disposed on the upstream side of the flow path switching device so as to be able to detect the flow of each water intake pipe,
At least one water intake pipe passing through the flow-nt detection passage of these flow switch valves passes through the flow opening/closing passage of the flow switch valve provided in the other water intake pipe, upstream or downstream of the flow switching device. This is achieved by plumbing the

Another object of the present invention is to provide the electrolyzed water generating device with a drainage switching valve for selectively switching the intake pipe to the drain side in at least one of the water intake pipes on the downstream side of the flow path switching device. This is achieved by

[Action of the invention]

As described above, the present invention provides a two-stage flow switch valve on the upstream side of the flow switching device of a pair of electrolyzed water intake pipes, and the water intake pipe passing through the flow 1il detection device of one of the flow switch valves. Is it because it passes through the opening/closing passage of the other flow switch valve? Th M When the polarity of the voltage is switched, the electrolyzed water passing through the electrode chamber of the electrolytic cell, the water intake pipe from the electrolytic cell to the flow switching device, and the flow switch valve is switched from alkaline water to acidic water, and precipitated calcium is dissolved. Ru. In this case, when the faucet 1, etc. of the intake channel on the user side is opened and closed and the diversion detection device of one flow switch valve is activated, the other water intake pipe passing through the opening/closing passage of this flow switch valve is also opened and closed, and the pair of intake pipes are opened and closed. The water pipes are controlled to open and close in conjunction with each other.

If the flow switching device is configured with a pair of poppet valves installed in each water intake pipe, and a drainage switching valve is provided in the intake pipe downstream of this flow switching device, the poppet valve and the drainage switching valve It is possible to configure a water drain circuit that drains water from a pair of water intake pipes from a common drain separate from each water intake port at the timing of operation. If this water drain circuit is formed when the polarity of the voltage is switched, the water mixed with alkaline water and acidic water will flow to the drain, and water of the other nature will not mix into the water intake pipe.

[Embodiments of the invention]

Hereinafter, the present invention will be described in detail with reference to the drawings.

The electrolyzed water generating device of the present invention has an electrode 1 to which an electrolytic voltage is applied.
．． It has an electrolytic cell 4 which is partitioned into a pair of electrode chambers by an electrolytic diaphragm 3, and alkali ionized water and acidic water are taken out separately from one side of the electrolytic cell 4. This electrolyzed water generating device is a pressure-type device that pumps raw water from a water supply vibrator 5 and controls the water supply to the electrolytic cell 4 with an opening/closing means 8 such as a faucet provided on the electrolyzed water intake channel side.

In addition, the electrolytic cell 4 uses a cathode-anode dual-use electrode 1.2 that can perform electrolytic operation by changing the polarity of the applied voltage, and the control section 9 of the electric circuit for the applied voltage changes the polarity of the voltage at regular intervals. A converting function is provided so that the electrolyzed water discharged from the water intake pipes 6 and 7 is changed from alkaline water to acidic water or from acidic water to alkaline water at regular intervals.

This type of electrode conversion type electrolyzed water generation device has a pair of water intake pipes 6 and 7 so that alkaline water is always discharged from the alkaline water intake [1] and acidic water is always obtained from the acidic water intake. A flow path switching device 10 is provided.

The feature of the present invention is that in the pressure-type electrolyzed water generating device having the above configuration and capable of switching electrodes, it has two systems of fluid passages, the flow rate detection passage 12 and the flow passage opening/closing passage 13, and detects the flow rate of the detection passage. A two-stage flow switch valve 11 is connected to each water intake pipe 7.8 on the upstream side of the flow path switching device 10 to ON-OFF control the electrolysis operation of the electrolyzer and to control the opening and closing of the opening/closing passage in conjunction with this. These flow switch valves 11. are arranged so that the flow can be detected.
Upstream or downstream of at least one water intake pipe 7 or 8 passing through the 11 flow rate detection passages 12 and the flow switching device 9, the flow passage opening/closing passage 13 of the flow switch valve 11 provided in the other water intake pipe 8 or 7 is connected. The reason is that the piping was designed to pass through it.

In the embodiment shown in FIG. 1, one water intake pipe 6 or 7 passing through the flow rate detection passage 12 of the two-stage flow switch valve 11 is on the upstream side of the flow switching device 10, and the other water intake pipe 8 or 7
The water intake pipes 6 and 7 are arranged so that the water intake pipes 6 and 7 cross each other in each of the pair of flow switch valves 11 and 11, In addition, in the embodiment shown in FIG. 2, one water intake pipe 6 or 7 passing through the flow rate detection passage 12 of the flow switch valve 11 connects to the other water intake pipe via the switching valve 14 on the downstream side of the flow switching device 1o. The piping is arranged so as to pass through the channel opening/closing passage 13 of the flow switch valve II of No. 7 or No. 6.

The two-stage flow switch valve 11 is shown in FIGS. 3a and 3b.
As shown in the figure, two systems of fluid passages, a passage 12 for detecting flow rate and a passage 13 for opening and closing the passage, are provided in the valve casing 111 in upper and lower stages.
The valve seats 113A and 113B of both passages are opened and closed in conjunction with each other. Valve seat 113 of flow rate detection passage 12
A chamber 115 having a variable volume h1 is provided above the diaphragm 114, and the valve body 112 is supported by this diaphragm.

The chamber 115 and the valve seat downstream of the flow rate detection passage 12 (output [
The diaphragm 114 moves up and down due to the pressure difference between the chamber 115 and the passage on the downstream side of the valve seat, and the valve body 112 integrated with the diaphragm 114 moves up and down. The two channels 12 and 13 are opened and closed in conjunction with each other.

Further, a magnet 117 is attached to the upper end of the valve body 112, and a transmitting device 118 such as a reed switch is provided on the wall of the housing opposite to this, and a flow rate detection signal is generated by vertical movement of the valve body 112. It is now being sent.

Therefore, as shown in the figure, the water intake circuit 6.7 is connected to the flow-41 detection passage 12 and the flow passage opening/closing passage 13 of this two-stage flow switch valve 11, and the flow switch valve 11
If the electric circuit is configured so that an electrolytic voltage is applied when the flow rate detection passage II is opened, by opening and closing the end of the water intake circuit 6 or 7 leading to the outlet side of the flow rate detection passage II with an opening/closing means 8 such as a faucet. The water intake passages 6 and 7 both open and close, and in response to the opening and closing of the flow rate detection passage 12 communicating with the opening and closing means 8, the electrolytic operation is controlled ON-OFF.

In addition, FIG. 3a shows a two-stage flow switch valve of the type in which the valve body 112 can be forcibly opened from the outside by means of an operation stick 119, and this valve has a pair of water intake pipes 6, 7 is used in an embodiment (for example, FIG. 1) in which the flow switch valves II and 11 cross each other on the upstream side of the flow switching device 10.

Furthermore, the flow switch valve shown in Fig. 3b is not equipped with an external operation stick, and this valve is not equipped with an operating rod from the outside.
This is used in embodiments (for example, the embodiment in FIG. 2) in which one of the intake channels on the downstream side of the flow switch valve 11.

Thus, in the embodiment shown in FIG. 1, the opening/closing means 8 is opened, and the flow opening/closing passage 13 of the water intake pipe (water intake pipe 6 in the figure) communicating with the opening/closing means 8 is opened from the outside using the operating rod 119. When this is done, the pair of water intake pipes 6 and 7 will both flow,
Moreover, the electric circuit for the electrolytic voltage is turned on, and alkaline water and acidic water are drained separately from the pair of water intake pipes 6 and 7. In this case, the operating rod 119 only needs to be operated at the beginning of opening the opening/closing means 8, and this operation is generally performed electrically by a motor 120, a cam 121, etc. in conjunction with the flow path switching valve 10, etc. as shown in the figure. Of course, it may be operated manually.

On the other hand, in the embodiment shown in FIG. 2, the water intake pipe (water intake pipe 6 in the case of Fig. 2) that feeds the opening/closing means 8 passes only through the flow rate detection passage 12 of one of the flow switch valves. Just by opening the opening/closing means 8, the pair of water intake pipes 6 and 7 both flow with water. Therefore, there is no need to forcibly open the other flow switch valve from the outside as in the embodiment of FIG.

Thus, in both the embodiments of FIGS. 1 and 2, the flow switch valves 11 and 11 are installed upstream of the flow path switching device IO, so that when the polarity of the seven electrolytic pressures is switched, the flow switch valves are activated. 11 two-way passage 12.13
The flowing water changes from alkaline water to acidic water, which dissolves precipitated calcium and removes calcium during the production of electrolyzed water.

In addition, since the pair of water intake pipes 6 and 7 pass through the flow rate detection passage 12 and the flow passage opening/closing passage 13 of the flow switch valve which is controlled to open and close by the opening/closing means 8, the closing operation of the opening/closing means 8 is performed. will be closed at the same time.

By the way, in a polarity switching type electrolyzed water generation device, immediately after the polarity of the electrode is changed, the water remaining in the pipe before the polarity switching is discharged from the opposite water intake.

The embodiments shown in FIGS. 4 and 5 attempt to solve this problem at the same time, and in the devices of each embodiment shown in FIGS. A drain switching valve 16 is provided in the water intake pipe to selectively switch the water intake pipe to the drain side 15, thereby draining residual water from the drain when switching the polarity, and draining the remaining water from the water intake (opening/closing means 8 and water intake tank 17 in the figure). The method is such that alkaline water or acidic water with predetermined properties can always be obtained.

Although FIGS. 4 and 5 illustrate the case where the drainage switching valve 16 is provided in only one intake channel, when both alkaline water and acidic water are used, it is provided in both intake channels.

6a to 6C and 7a to 7C show the flow path switching device 10, the secondary switching valve 14, and the secondary switching valve 14 of the device shown in FIGS.
This is an example in which a poppet valve is used as the drain switching valve 16.

As shown in FIG. 8, this poppet valve 100 has one fluid manifold D l 01 and two upper and lower fluid outlets 102 and 103.
The fluid outlet 102 is located within a valve case 104 having a
, 103, a pair of upper and lower valve seats 105, 106 are provided, and the valve body 1 opens and closes the pair of valve seats 105, 106.
The valve rod 108 of No. 07 is slidably protruded to the outside of the valve case 104, and can be opened and closed from the outside.

Thus, in the embodiment shown in FIGS. 6a to 7c, the flow path switching device 10 includes two poppet valves 100a having the above structure,
100b, each water intake pipe 6゜7 is connected to the fluid inlet 101 of each poppet valve 100a, 100b, and the two fluid outlets 102, 103 of each poppet valve 100a, 100b are connected to two systems of electrolyzed water intakes. (In the figure, the opening/closing means 8 of one intake channel and the tank 17 of the other intake channel) are connected to each other through separate pipe lines. Therefore, each poppet valve can be reversely opened and closed with respect to the shared water intakes of the two systems with a desired timing or time difference.

In the embodiment shown in FIGS. 6a to 7C, similar poppet valves are used for the switching valve 14 and the drain switching valve 16. To explain this embodiment, the flow path switching device 10 is configured to include poppet valves 100a, 100b, 1o corresponding to the flow path switching device 10 and the secondary switching valve 14 in connection with polarity conversion of the electrodes.
The position of each valve body of the oc moves from Fig. 6a to Fig. 6C (or vice versa) and from Fig. 7a to Fig. 7C (or vice versa), and the flow path of the pair of intake pipes 6.7 A switch is made. In this case, by using a poppet valve, each valve can be opened and closed at desired timing, so when switching the polarity of the electrode, the water intake pipes 6 and 7 are connected to each other as shown in Figures 6b and 7b. It is possible to design such a drain drainage circuit (water drainage circuit) to be opened.

That is, in FIG. 6b, if the switching of the poppet valve 100b is delayed from the switching of the poppet valves 100a and 100d, both the water intake circuits 6 and 7 are connected to the drain 1 during the delay time.
It communicates only to the 5th side and drains water. Therefore, residual water from before electrode switching does not mix into the water intake. Further, if the water supply is stopped in this state, water will be drained from the pipe, and if the voltage application is stopped and only the water supply is continued, cleaning with raw water will be performed.

Similarly, in FIG. 7b, the poppet valve 1 of the drain switching valve 16
00d to the drain 15 side, and the flow path switching device 1
When the switching of the poppet valve 100a of 0 and the poppet valve 100C of the secondary switching valve 14 is delayed from the switching of the other poppet valve 100b of the flow path switching device 10, the water intake circuits 6 and 7 are closed during the delay time. Connects only to drain 15, No. 6
The same effect as in figure b is performed.

In both cases of Fig. 6b and Fig. 7b, the flow path switching valve IO
By using a poppet valve as the secondary switching valve 14, the drain circuit for both water pipes 6 and 7 can be opened by simply installing the drain switching valve 16 on either one of the water intake pipes 6 and 7. There are also advantages.

Preferably, these poppet valve groups have a cam 109 attached to the tip of the valve rod as shown in the figure, and a cam 109 corresponding to the valve rod of each poppet valve is provided on a common operating shaft 110 driven by a motor M. By appropriately adjusting the shape and angle of the cam surface, the series of valve operations described above can be performed. However, the driving means is not limited to a motor, a cam, etc., and can of course be controlled by a fluid pressure sequence.

Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to these embodiments only, and that various changes in shape can be made based on the same basic configuration and principle.

〔Effect of the invention〕

Since the present invention has the above configuration, the main passages of the device, including the passage of the flow switch valve, are switched from the alkaline water passage to acidic water at predetermined intervals, and calcium is dissolved. Therefore, chemical cleaning for removing precipitated calcium is completely unnecessary, and maintenance is significantly reduced. Moreover, the water supply can be stopped by the opening/closing means on the water intake side, eliminating the problem of overflow.

In addition, by using a poppet valve as a flow path switching device or a secondary switching valve, it is possible to time the opening and closing operations of each poppet valve, so the drain drainage circuit can be opened for a predetermined period of time when changing the flow path. Furthermore, it is possible to open and close the water drain circuit and the cleaning circuit at desired times, making it possible to simultaneously solve various problems of electrolyzed water generating devices that have been considered difficult in the past.
