Description

  The present invention relates to a water purification device for purifying water and a water ozone mixing device for mixing ozone with water.

  Conventionally, there is a demand to use water and rain water drawn from water sources such as wells and rivers as washing water and bath water, or to spray water for plant cultivation.

  However, recently, the quality of well water has been remarkably deteriorated due to changes in the strata itself and the penetration of pollutants into groundwater veins, and it has become difficult to use the well as it is pumped. Similarly, river water often deteriorates in water quality. The deterioration of water quality here means, for example, that the turbidity and chromaticity of water become high, or that an odor is generated from water.

  As such water quality deterioration, as described in Patent Document 1, for example, well water may be so-called “red water”. “Red water” is water in which the well water extracted from the well is changed to red as time passes because iron and manganese components are contained as ions. Therefore, “red water” is not suitable for use as washing water or bath water, and also has a problem of adversely affecting plant cultivation.

  In order to improve the quality of contaminated water such as well water and river water as described above, the iron treatment in the water is oxidized and removed by ozone treatment. A water-receiving type well improvement device that can sterilize bacteria, E. coli, viruses, and the like has been proposed (see, for example, Patent Document 1).

  In addition, there is a desire to use ozone water mixed with tap water to generate ozone water, which can be used, for example, for sterilization cleaning of limbs, sterilization / deodorization / slimming of toro boxes containing fresh fish, etc. There is also.

In order to generate ozone water as described above, an ozone water generation system having excellent sterilization / deodorization performance has been proposed by mixing tap water and ozone (see, for example, Patent Document 2).
Japanese Patent No. 2715244 JP 2003-305348 A

  The water quality improvement device described in Patent Document 1 is a device in which a large water receiving tank, a first stage treatment machine, and a second stage treatment machine are combined in a complex manner.

  By the way, in Indonesia, for example, there are areas where water supply infrastructure is not in place. In such areas, well water or river water containing red water pumped out by dredging, accumulated rainwater, etc. Is used for domestic use. Therefore, there is a high demand for introducing a water quality improvement device in such an area, and it is desirable that the configuration of the water quality improvement device be as simple as possible. However, a device having a large and complicated configuration like the water quality improvement device described above. Then, it is difficult to introduce.

  Moreover, in the said water quality improvement apparatus, the ozone generator is arrange | positioned below the ozone addition part.

  In general, the ozone generator has a configuration that generates ozone by taking in the surrounding air and discharging at a high voltage, so that the ozone generator cannot be discharged if it is exposed to water. There is. Moreover, when the power source of the ozone generator exposed to water is turned on, there is a risk of electric leakage or electric shock, and there is a problem in handling. Of course, not only the ozone generator but also other electrical components such as a controller are the same. For this reason, it is desirable to prevent water from entering the ozone generator. However, in the configuration in which the ozone generator is disposed below the ozone addition unit as in the water quality improvement device, the water in the ozone addition unit is used. However, due to its own weight, it may enter the ozone generator through the ozone introduction pipe.

  Therefore, in order to improve these problems, the ozone water generation system described in Patent Document 2 can be used universally regardless of the flow path conditions, and the ozone generator can be used in the water supply line. It is proposed to introduce the configuration of a system provided above an injector that is an inlet for mixing ozone into water flowing through the water quality improvement apparatus. However, even when this system configuration is introduced, if the water supply line is filled with water when the system power is turned off, minute water leaks from the check valve provided in the injector. In some cases, water may enter the ozone generator.

As a result, it is possible to easily perform maintenance such as, for example, periodic parts replacement and repair of a failed part. Moreover, the water purifier can be made compact by integrating the ozone generator, the gas-liquid mixer, and the control device in a casing.

  According to the second aspect of the present invention, it is possible to provide an easy-to-handle water purification device, and to make the water pressure discharged to the user use side always properly maintained and to have a good operability. Can do.

  According to the invention described in claim 3, the operation, control, and operation of the water purification apparatus are performed at a location related to the casing (on the casing surface or inside the casing). As a result, it is possible to easily perform maintenance such as, for example, periodic parts replacement and repair of a failed part. The purified water is returned to the water storage source again. Therefore, the purified water can be stored in the water storage source, and the purified water can be used easily. Furthermore, when the device is operated with solar energy, water is made during daytime sunshine hours, and the device is prepared for use at night.

The height difference between the purification device and the water storage tank can be reduced, and the loss of the water head when the water stored in the water storage tank reaches the purification device can be suppressed. As a result, the pressure loss of the water flowing through the gas-liquid mixer of the purification device can be prevented, so that a decrease in the suction flow rate of ozone mixed with water in the gas-liquid mixer into the gas-liquid mixer can be suppressed. It is possible to prevent a decrease in gas-liquid mixing efficiency. Therefore, in this water purification apparatus, the water quality can be satisfactorily improved with a simple configuration.

  Moreover, since the pump which is a heavy article is generally arrange | positioned in the position lower than a purification apparatus, the attitude | position of a water purification apparatus can be stabilized.

  According to the sixth aspect of the present invention, since water in which foreign matter has been captured by the filter is introduced into the purification device, foreign matter is prevented from being clogged in a portion where water flows inside the purification device, such as a gas-liquid mixer. it can.

  And since this filter is provided in the middle of the introduction path, it is arrange | positioned upstream from the purification | cleaning apparatus seeing in the flow direction of water. In general, when water passes through the filter, the filter becomes a resistance, so that pressure loss occurs in water near the filter. Therefore, when the filter is disposed downstream of the purification device, the pressure loss described above occurs on the downstream side of the purification device, so that the gas-liquid mixer of ozone mixed with water in the gas-liquid mixer. There is concern about a decrease in the suction flow rate. However, in the present invention, since the filter is arranged on the upstream side of the purification device, the above-described decrease in the ozone suction flow rate into the gas-liquid mixer can be suppressed, and the decrease in the efficiency of gas-liquid mixing can be prevented. Can do. Thereby, in this water purification apparatus, water quality can be satisfactorily improved with a simple configuration.

  According to the seventh aspect of the present invention, when the filter is clogged, the flow of water in the introduction path and the purification device deteriorates. Therefore, the gas-liquid of ozone mixed with water in the gas-liquid mixer of the purification device There is concern about a decrease in the suction flow rate into the mixer. However, in the present invention, the clogged state of the filter can be managed by detecting the pressure of the water flowing between the pump and the filter. Then, the control means determines the filter clogging according to the pressure value detected by the pressure sensor, and the notification means notifies the filter clogging according to the determination, whereby the filter is accidentally clogged. Therefore, the above-described decrease in the ozone suction flow rate can be suppressed, and the decrease in the efficiency of gas-liquid mixing can be prevented.

  Further, as the water storage tank is arranged at a higher position, as described above, there is a concern that the ozone suction flow rate into the gas-liquid mixer decreases. If the filter is clogged there, there is a concern about further decrease in the ozone suction flow rate into the gas-liquid mixer. Therefore, in order to prevent a decrease in the suction flow rate of ozone due to filter clogging, it is desirable to detect filter clogging as soon as possible, but in a configuration where the pump is arranged at a position lower than the water storage tank, As the water storage tank is arranged at a higher position, the pressure sensor detects a higher pressure value, so that the filter clogging is determined earlier than the actual and is notified to the user. Thereby, the fall of the suction | inhalation flow rate of ozone to the gas-liquid mixer resulting from the clogging of a filter can be prevented.

  According to invention of Claim 8, since electrical components, such as an ozone generator and a control apparatus, are arrange | positioned in the electrical component area | region divided above the water channel, even if water leaked from the water channel, it leaked There is no risk of water reaching the ozone generator and the controller due to its own weight. Furthermore, since this electrical component area is cut off from the water channel by the blocking wall, for example, even if water scatters from the water channel during maintenance, the water is reliably prevented from entering the ozone generator and the control device. be able to.

  According to the ninth aspect of the present invention, there is no refracting portion in the water channel extending substantially horizontally in the left-right direction within the housing. If there is a refracted portion, it is necessary to separately provide a connecting part such as an elbow tube. In that case, not only the number of parts increases, but also there is a risk of water leakage from the connecting part between the connecting part and the water channel. These fears are eliminated by the water channel of the present invention, and the inundation of the ozone generator and the control device can be more reliably prevented.

  In addition, one end of the water channel protrudes outwardly from one side of the housing and is connected to the introduction passage at the outside, and the other end protrudes outward from the other side of the housing and is connected to the lead-out passage at the outside. . At one end and the other end of the water channel that becomes the connection portion with the introduction channel and the outlet channel, there is a possibility that water leakage may occur, but these one end and the other end both protrude outward from the side surface of the housing, It is not located inside the housing. Therefore, even if water leakage occurs at one end and the other end of the water channel, it is possible to more reliably prevent the ozone generator and the controller inside the casing from being flooded.

  According to the invention described in claim 13, there is a coupling portion between the water channel and the component that can be removed at the time of maintenance, and there is a possibility that water leakage may occur at the coupling portion. Since it is arrange | positioned upwards, the inundation of an ozone generator and a control apparatus can be prevented more reliably.

  According to the fourteenth aspect of the present invention, it is desirable that the electrical components such as the ozone generator and the control device are disposed on the back side of the housing in order to take in electric power from the outside. On the other hand, the water channel can be easily maintained by being disposed on the near side. In addition, since such an arrangement relationship causes a gap between the ozone generating device and the control device arranged on the back side and the water channel arranged on the near side, even if water leaks from the water channel, Inundation of the generator and the controller can be reliably prevented.

  According to the fifteenth aspect of the present invention, when the ozone generator is disposed above the gas-liquid mixer, the distance between the ozone generator and the gas-liquid mixer is relatively narrow. In this case, the supply pipe cannot be connected between the ozone generator and the gas-liquid mixer with an appropriate curvature, and is bent unnaturally on the way, and ozone from the ozone generator is turned into the gas-liquid mixer. There is a possibility that it cannot be supplied smoothly. However, in the present invention, the control device is disposed above the gas-liquid mixer, and the ozone generator is disposed so as to line up with the control device in the crossing direction intersecting the vertical direction. Thereby, since the space | interval of an ozone generator and a gas-liquid mixer can be made comparatively wide, a supply pipe can connect between an ozone generator and a gas-liquid mixer with an appropriate curvature, and ozone Ozone from the generator can be smoothly supplied to the gas-liquid mixer.

  According to the invention described in claim 16, the ozone generator needs to take measures against flooding more than other electrical components. However, the ozone generator is disposed further above the water channel by being disposed above the control device. Therefore, it is possible to more reliably prevent the ozone generator from being flooded.

  According to the invention described in claim 17, since the electrical components such as the ozone generator and the control device are arranged in the electrical component area partitioned above the water channel, even if water leaks from the water channel, it leaked out. There is no risk of water reaching the ozone generator and the controller due to its own weight. Furthermore, since this electrical component area is cut off from the water channel by the blocking wall, for example, even if water scatters from the water channel during maintenance, the water is reliably prevented from entering the ozone generator and the control device. be able to.

  According to the eighteenth aspect of the invention, since the blocking wall is disposed above the portion where water leakage may occur, such as the coupling portion of the water channel and the gas-liquid mixer, the ozone generator and the control device are submerged. This can be prevented more reliably.

  According to the nineteenth aspect of the present invention, there is a coupling portion between the water channel and the component that can be removed at the time of maintenance, and there is a possibility that water leakage may occur at the coupling portion. Since it is arrange | positioned upwards, the inundation of an ozone generator and a control apparatus can be prevented more reliably.

  According to the twentieth aspect of the present invention, there is no refracting portion in the water channel extending substantially horizontally in the left-right direction within the housing. If there is a refracted portion, it is necessary to separately provide a connecting part such as an elbow tube. In that case, not only the number of parts increases, but also there is a risk of water leakage from the connecting part between the connecting part and the water channel. These fears are eliminated by the water channel of the present invention, and the inundation of the ozone generator and the control device can be more reliably prevented.

  In addition, one end of the water channel protrudes outwardly from one side surface of the housing, and the other end protrudes outwardly from the other side surface of the housing. There is a possibility that water leakage may occur at one end and the other end of the water channel that is a connection part with other parts. However, both the one end and the other end protrude outward from the side surface of the casing. It is not located inside. Therefore, even if water leakage occurs at one end and the other end of the water channel, it is possible to more reliably prevent the ozone generator and the controller inside the casing from being flooded.

  And since a water channel is supported by the 1st side and other side of a housing | casing, it can arrange | position stably in a housing | casing and the assembly | attachment to the housing | casing of a water channel becomes easy.

  According to the invention of claim 21, since the gas-liquid mixer is coupled to the water channel so as to constitute one end or the other end of the water channel, compared with the case where the gas-liquid mixer is coupled in the middle of the water channel. Thus, the coupling portion between the gas-liquid mixer and the water channel, that is, the portion where water leakage may occur can be reduced, and the ozone generator and the control device can be more reliably prevented from being flooded.

  According to the twenty-second aspect of the present invention, since the water flow path of the gas-liquid mixer constitutes the water channel, the portion where the gas-liquid mixer and the water channel are coupled, that is, the portion where water leakage may occur is eliminated. It is possible to prevent the inundation of the ozone generator and the controller more reliably.

  According to the twenty-third aspect of the present invention, it is desirable that the electrical components such as the ozone generator and the control device are arranged on the back side of the housing in order to take in electric power from the outside. On the other hand, the water channel can be easily maintained by being disposed on the near side. In addition, since such an arrangement relationship causes a gap between the ozone generating device and the control device arranged on the back side and the water channel arranged on the near side, even if water leaks from the water channel, Inundation of the generator and the controller can be reliably prevented.

  According to invention of Claim 24, when an ozone generator is arrange | positioned above a gas-liquid mixer, the space | interval of an ozone generator and a gas-liquid mixer becomes comparatively narrow. In this case, the supply pipe cannot be connected between the ozone generator and the gas-liquid mixer with an appropriate curvature, and is bent unnaturally on the way, and ozone from the ozone generator is turned into the gas-liquid mixer. There is a possibility that it cannot be supplied smoothly. However, in the present invention, the control device is disposed above the gas-liquid mixer, and the ozone generator is disposed so as to line up with the control device in the crossing direction intersecting the vertical direction. Thereby, since the space | interval of an ozone generator and a gas-liquid mixer can be made comparatively wide, a supply pipe can connect between an ozone generator and a gas-liquid mixer with an appropriate curvature, and ozone Ozone from the generator can be smoothly supplied to the gas-liquid mixer.

  According to the invention described in claim 25, the ozone generator needs to take measures against flooding more than other electrical components. However, the ozone generator is disposed further above the water channel by being disposed above the control device. Therefore, it is possible to more reliably prevent the ozone generator from being flooded.

The gas passage 16 has a check valve 17 in the middle thereof and a three-way branch 18 below the check valve 17. An inlet 19 as a gas inlet that opens to the side of the three-way branch 18 is an inlet into which ozone enters, and an outlet 20 as a gas outlet at the upper end from which ozone exits is T-shaped with respect to the throttle portion 15. Communicated in a shape.

  The flow rate of water flowing in from the inflow port 12 is increased in the throttle portion 15. Due to the flow of water with the increased flow velocity, the inside of the throttle portion 15 becomes a negative pressure. Due to this negative pressure, the ozone that has flowed into the gas passage 16 is sucked into the water flow path 14 from the outlet 20, and has a diameter, for example. Are mixed in water as ultrafine bubbles (so-called microbubbles) of 50 μm or less. Thus, when the throttle part 15 is provided in the water flow path 14 to form a venturi structure, for example, a device such as a blower is not provided, and the water flow path 14 is utilized by using the negative pressure generated by the flow of water in the throttle part 15. Ozone can be efficiently taken into the inside.

  In addition, in this embodiment, although the ozone mixer 7 was demonstrated as a venturi structure, as the ozone mixer 7, a T-tube etc. can be used, for example. If it is a T-shaped tube, there is no throttle part 15 and there is no portion with a small diameter in the water channel, so that the water channel can be prevented from being clogged with foreign substances.

  Referring to FIG. 2, ozone supply device 8 has an ozone generator 21 that converts oxygen in the air into ozone by discharging the air.

  The ozone generator 21 has a discharge element circuit (not shown) and a discharge electrode plate (not shown) therein, and is electrically connected to a control unit 49 (described later).

  Further, the ozone supply device 8 is inserted into an intake pipe 22 for sucking air outside the casing 27 described later, a filter 23 inserted into the intake pipe 22, an ozone supply pipe 24 as a supply pipe, and an ozone supply pipe 24. The check valve 17 is included, the intake pipe 22 is connected to the intake port 25 of the ozone generator 21, and the ozone supply pipe 24 is connected to the exhaust port 26 of the ozone generator 21. When the ozone generator 21 is turned on by a control unit 49 (described later), the air taken into the ozone generator 21 from the intake port 25 is discharged by an electrode plate (not shown) (for example, creeping discharge, Ozone is generated by being silently discharged. Since dust contained in the air flowing from the air inlet 25 is captured by the filter 23, the dust is mixed into the ozone generator 21, and the discharge element (not shown) and the electrode plate (not shown) are damaged. This can be prevented.

  The generated ozone flows out from the exhaust port 26 and can be supplied to the inlet 19 of the three-way branch 18 through the check valve 17 and the ozone supply pipe 24 (see FIG. 3).

  Ozone is supplied by the ozone mixer 7, and the water purified by sterilization and sterilization by ozone flows through the purified water supply pipe 9, and the residual ozone is decomposed in the ozone deodorizing column 10 and supplied to the user side. The The ozone decomposition in the ozone deodorization column 10 will be specifically described. The ozone deodorization column 10 is filled with, for example, activated carbon, and this activated carbon and unreacted ozone remaining in the purified water undergo an oxidation reaction. Thus, unreacted ozone is decomposed. By being decomposed in this way, ozone does not exist in the water supplied to the user use side, and the user can use the purified water with peace of mind.

  Water is purified according to the flow described above, and the purified water is supplied to the user. In the water purification apparatus 1, such water purification is performed in a housing 27 in which the water ozone mixing apparatus 2 is accommodated (see FIG. 1).

  The casing 27 is disposed above the pump 5, and an operation display section 55 is formed on the surface of the casing 27 as an operation section that performs various operations and various displays related to the operation of the water purification device 1. The operation display unit 55 is electrically connected to a control unit 49 (described later). Therefore, the user can operate the water purification apparatus 1 by operating the operation display unit 55 to give an instruction to the control unit 49 (described later) and know the operation state.

  Further, as described above, the housing 27 accommodates the control unit 49 that is electrically connected to the pump 5 and the ozone generator 21. As described above, the operation display unit 55 is formed in the housing 27 as a purification device related to the operation / control / operation of water purification, and the ozone generator 21, the ozone mixer 7, and the control unit 49 are installed in the housing 27. Therefore, the user can easily perform maintenance such as periodic replacement of parts and repair of a failed part, for example. The electrical configuration of the control unit 49 will be described later in detail with reference to FIG.

  The ozone deodorizing column 10 is attached to the outer surface of the casing 27. Since the ozone deodorization column 10 is provided in the vicinity of the casing 27, maintenance of the ozone deodorization column 10, for example, replacement of activated carbon filled in the ozone deodorization column 10 or replacement of the ozone deodorization column 10 main body, etc. Can be easily performed. Furthermore, since it is provided not on the inside of the casing 27 but on the outside, it is not necessary to open the lid of the casing 27 when performing maintenance.

  Further, in the casing 27, the ozone generator 21 is disposed above the three-way branch 18. For this reason, even if water may enter the three-way branch 18, the water can be prevented from entering the ozone generator 21.

  1, for example, the raw water supply pipe 6 (downstream of the elbow pipe 28) and the purified water supply pipe 9 (upstream of the ozone deodorizing column 10) can be attached and detached, and the casing 27 needs to be purified of water. It can also be configured so that it can be carried to the place where it will be.

  Referring to FIG. 3 again, a check valve 17 is inserted in the gas passage 16 connected to the water flow path 14. The check valve 17 allows a flow (especially ozone flow) flowing from the bottom to the top in the gas passage 16 but prevents a flow flowing from top to bottom (especially water flow).

  Here, a configuration example of the check valve 17 will be described with reference to FIG. FIG. 4 is an illustrative view of the check valve 17. FIG. 4A shows a state when water is not flowing in the water flow path 14 (hereinafter, referred to as normal time), and FIG. The state when water is flowing in the water flow path 14 (hereinafter referred to as “at the time of suction”) is shown. In FIG. 4, broken line arrows indicate gas flow.

  The check valve 17 includes a valve chamber 29, a ball valve 30 that can move in the valve chamber 29, and an inlet 31 formed on one side (for example, the lower side) and the other side (for example, the upper side) of the valve chamber 29. And an outlet 32 and a spring 33 that urges the ball valve 30 to always block the inlet 31. The shape of the valve chamber 29 is a rocket shape that tapers upward in this example, but is not limited thereto. The point is that the ball valve 30 can move in the valve chamber 29 and the fluid can move between the inlet 31 and the outlet 32 when the inlet 31 is not blocked.

  The ball valve 30 is, for example, a known sphere such as rubber or resin, and has a diameter larger than that of the inlet 31.

  The spring 33 has a biasing force that allows the ball valve 30 to move upward due to negative pressure during suction. The spring 33 exemplifies a coil spring, but may be, for example, a bar spring or a plate spring.

  As shown in FIG. 4A, the check valve 17 is normally closed at the inlet 31 by the weight of the ball valve 30 and the biasing force of the spring 33. For this reason, even if water enters the valve chamber 29, the water is blocked in the valve chamber 29.

  On the other hand, at the time of suction, as shown in FIG. 4B, the ball valve 30 is sucked by negative pressure, and the blocked inlet 31 is in communication with the inside of the valve chamber 29. Therefore, the path connecting the ozone generator 21 → the ozone supply pipe 24 → the inlet 19 of the three-way branch 18 → the gas passage 16 is communicated, and ozone is supplied to the gas passage 16. At the time of suction, since water flows in the water flow path 14, the water does not leak from the outlet 20 to the gas passage 16.

  Further, if the check valve 17 is provided, for example, the water flow path 14 is switched from the suction state to the normal state and the water flow path 14 is caused by a water hammer phenomenon that occurs when the flow of water in the water flow path 14 is suddenly stopped. Even if water enters the gas passage 16 from the outlet 20, the inlet 31 of the valve chamber 29 is blocked by the ball valve 30, so that the water that has entered is blocked by the check valve 17. . Therefore, it is possible to prevent water from entering the downstream side of the check valve 17, that is, the ozone generator 21 side. Even if the check valve 17 inserted in the gas passage 16 is damaged and water passes through the check valve 17, the check valve 17 is further connected to the ozone supply pipe 24. Since 17 is inserted, water can be blocked by the check valve 17, and water can be prevented from entering the ozone generator 21.

  A plurality of check valves 17 in the gas passage 16 may be arranged in series if necessary.

  Referring to FIG. 3, the three-way branch 18 is provided with a drain port 34 opened downward in addition to the inlet 19 described above, and the drain port 34 entered the gas passage 16. A drain pipe 35 as a drain channel for draining water is connected (see FIG. 2).

  The drain pipe 35 extends downward from the three-way branch 18, and a drain valve 36 is provided in the middle of the drain pipe 35 for suppressing air from flowing through the drain pipe 35 during ozone supply. . Moreover, the outlet of the lower end of the drain pipe 35 is provided with a water tray 37 for receiving water flowing out from the outlet (see FIG. 2).

  The drain pipe 35 is for draining water that has entered the gas passage 16 to the outside. As described above, since the check valve 17 is inserted in the gas passage 16, normally, the infiltrated water is blocked by the ball valve 30. In some cases, water leaks from a slight gap with 31 and flows down to the drain pipe 35 via the three-way branch 18. Even in such a case, since the drain pipe 35 is provided, the water that could not be blocked by the check valve 17 can be drained to the outside.

  Further, the flow path diameter of the drain pipe 35 is designed so that a water amount equal to or larger than the water amount leaking from the outlet 20 to the gas passage 16 per certain time (for example, 10 minutes) can be drained. Therefore, for example, even when the check valve 17 is not provided or when the check valve 17 is damaged, the water leaked into the gas passage 16 does not stagnate in the drain pipe 35 and smoothly flows to the outside. Drained. That is, it is possible to prevent water from stagnating in the drain pipe 35 and flowing out from the inlet 19 of the three-way branch 18 to the ozone generator 21 side.

  The drain valve 36 is a valve for suppressing air from flowing in the direction opposite to the water flow direction of the drain pipe 35 during ozone supply.

  Here, with reference to FIG. 5, the structural examples, such as the drain valve 36 and the water tray 37, are demonstrated. FIG. 5 is an illustrative view showing an example of the drain valve 36. FIG. 5 (a) shows a normal state, and FIG. 5 (b) shows a suction state. In FIG. 5, a solid line arrow indicates a water flow, and a broken line arrow indicates a gas flow. Moreover, about FIG.5 (b), the figure which shows structures, such as the water tray 37 shown to Fig.5 (a), is abbreviate | omitted.

  Referring to FIG. 5, the drain valve 36 has a valve chamber 38 and a ball valve 39 accommodated in the valve chamber 38.

  An inlet 40 is formed on the upper surface of the valve chamber 38. A recess 41 in which the ball valve 39 is located under its own weight is formed on the lower surface of the valve chamber 38, and an outlet 42 is formed on the lower surface avoiding the recess 41. The drain valve 36 is inserted into the drain pipe 35 so that the flow path connecting the inlet 40 and the outlet 42 becomes a part of the flow path of the drain pipe 35.

  The ball valve 39 is, for example, a known sphere such as rubber or resin, and is formed larger than the diameter of the inlet 40.

  As shown in FIG. 5A, the ball valve 39 is normally positioned in the recess 41 in the valve chamber 38 due to its own weight. Therefore, the water falling through the drain pipe 35 is drained through the drain valve 36.

  On the other hand, at the time of suction, as shown in FIG. 5B, the ball valve 39 is sucked by negative pressure and the inlet 40 is closed. Therefore, the drain pipe 35 located upstream from the drain valve 36 is blocked from the outside through the drain valve 36.

  The interior of the water tray 37 is partitioned into two rooms by a partition wall 73 that is lower than the height of the peripheral wall of the water tray 37, and one of the two rooms is drained from the outlet of the drain pipe 35. The other chamber is an overflow chamber 75 into which the water that has overflowed beyond the partition wall 73 enters. A discharge pipe 76 that leads to the outside of the casing 27 is connected to the overflow chamber 75 (see FIG. 2). The water drained from the outlet of the drain pipe 35 is once received in the water receiving chamber 74, and when the water level is below the height of the partition wall 73, it does not overflow into the overflow chamber 75 and evaporates with time. . On the other hand, when the water level exceeds the height of the partition wall 73, the excess amount overflows into the overflow chamber 75 as shown by the solid line arrow in FIG. Is done.

  A water leak sensor 45 is provided at a position slightly lower than the upper end portion of the partition wall 73 on the peripheral wall of the water tray 37.

  The water leak sensor 45 turns on when it detects that the water level stored in the water receiving chamber 74 is equal to or higher than a predetermined water level (for example, the height of the broken line in FIG. 5A), and otherwise. It is a sensor that turns off. The ON / OFF signal of the water leak sensor 45 is given to the control unit 49. When the water leak sensor 45 is turned ON by the control signal and a predetermined time elapses, the pump 5 and the ozone generator 21 are turned off by the control unit 49. Is done. The flow of detection by the water leak sensor 45 will be described in detail later with reference to FIG.

  A second configuration example of the drain valve 36 will be described with reference to FIG.

  The drain valve 36 of the second configuration example has a valve chamber 38 and a disc valve 46 accommodated in the valve chamber 38. A stopper 47 that receives the disc valve 46 is provided in the valve chamber 38. The valve chamber 38 has an inlet 40 formed on the upper surface, and a large outlet 42 formed on the lower surface below the stopper 47.

  The disk valve 46 is, for example, a known disk-shaped valve such as rubber or resin, and has a diameter larger than the diameter of the inlet 40.

  The stopper 47 is disposed at such a height that a gap 48 is formed between the periphery of the disc valve 46 and the inner wall of the valve chamber 38 when the disc valve 46 is received.

  As shown in FIG. 6A, the disc valve 46 is normally received by a stopper 47 due to its own weight. Therefore, the drain pipe 35 on the inlet 40 side and the drain pipe 35 on the outlet 42 side communicate with each other through the drain valve 36, and the leaking water is drained through the drain pipe 35.

  On the other hand, at the time of suction, as shown in FIG. 6B, the disc valve 46 is sucked by negative pressure and the inlet 40 is closed. A drain pipe 35 located on the upstream side of the drain valve 36 is blocked from the outside through the drain valve 36.

  Thus, during suction, that is, during ozone supply to the inlet 19, the drain pipe 35 is shut off from the outside through the drain valve 36, and external air passes through the drain pipe 35 through the three-way branch 18, Since it does not flow into the gas passage 16, it is possible to prevent the concentration of supplied ozone from being lowered, and to supply ozone at a constant concentration stably. As a result, water can be efficiently purified. Further, since the drain pipe 35 can be shut off by using the negative pressure generated in the throttle portion 15, it is not necessary to perform a separate operation and the inflow of air from outside can be automatically prevented. .

  In this embodiment, the inflow of air during ozone supply is blocked by the drain valve 36. However, instead of the drain valve 36, for example, an electromagnetic valve is provided and controlled by the control unit 49 (described later). You can also. In this case, during operation of the water purification apparatus 1, the electromagnetic valve is closed so that air does not flow in. When the water purification apparatus 1 is stopped, the electromagnetic valve is opened so that water leaking from the outlet 20 can be drained.

  The water purification apparatus 1 includes, for example, an ozone supply control means for controlling the pump 5, the ozone generator 21, and the like, and a control unit 49 as a control device. It is housed inside and connected to an external power source 50 (see FIG. 2). Here, the controller 49 will be described with reference to FIG.

  FIG. 7 is a block diagram showing an electrical configuration of the water purification device 1 and shows a portion related to the present invention.

  The control unit 49 is constituted by, for example, a microcomputer, and includes a CPU 51, a ROM 52, a RAM 53, and a timer 54. The control unit 49 is electrically connected to the operation display unit 55, the ozone generator 21, the pump 5, the water leak sensor 45, and the pressure sensor 11, respectively.

  The operation display unit 55 includes a power switch 56 for turning on / off the control unit 49, an ozone switch 57 for turning on / off the ozone generator 21, and a power LED 58 for performing various displays to the user. In addition, an ozone LED 59 and an abnormal LED 60 are provided.

In the configuration of the water purification device 1 described above, the portion composed of the ozone mixer 7, the ozone supply device 8, the drain pipe 35, and the drain valve 36 is the water ozone mixing device 2 according to the present invention. In the water purification device 1, when the user operates the operation display unit 55, the water ozone mixing device 2 is controlled by the control unit 49, so that ozone is mixed with water and the water is purified. It is.
(Control of water purification device 1)
FIG. 8 is a flowchart showing the control operation of the control unit 49 related to the purified water supply of the water purification device 1. Hereinafter, with reference to FIG. 8, the control regarding the purification water supply of the water purification apparatus 1 is demonstrated.

  When the power switch 56 is turned on by the user (Yes in step S1), it is determined whether or not the ozone switch 57 is turned on (step S2). If the ozone switch 57 is not turned on (No in step S2), the pump 5 is controlled independently (step S9). That is, only the pump 5 is turned on, and ozone is not supplied to the water of the water source 3 but is supplied as it is to the user side. On the other hand, when the ozone switch 57 is turned on (Yes in step S2), the pump 5 and the ozone generator 21 are interlocked and controlled (step S3). That is, when the user opens the faucet or the like, the water pressure in the flow path drops and the pressure sensor 11 is turned on (Yes in step S4), both the pump 5 and the ozone generator 21 are turned on (step S5). Purified water supply is performed in which water from the water source 3 is purified by ozone and supplied.

  Then, when the pressure sensor 11 is turned OFF during purification water supply (Yes in Step S6), it is determined whether or not T1 seconds, for example, 1 second has elapsed since the pressure sensor 11 was turned OFF (Step S7). When T1 seconds have elapsed (Yes in step S7), the pump 5 and the ozone generator 21 are turned off (step S8), and the purified water supply is completed. The user can also end the purified water supply by turning off the power switch 56. In addition, when the user wants to use the purified water again after the water supply is completed, it is only necessary to open the faucet. That is, when the user opens the faucet, the pressure sensor 11 is turned on again (Yes in step S4), and the pump 5 and the ozone generator 21 are automatically turned on in conjunction with this, so the user uses clean water. can do.

  Thus, by controlling the pump 5 and the ozone generator 21 in conjunction with each other, it is possible to provide the water purification device 1 that is easy to operate and easy to handle. Moreover, since the water pressure in the flow path is controlled by the pressure sensor 11, the water pressure discharged to the user use side is always properly maintained, and the water purification device 1 with good operability can be obtained.

  FIG. 9 is a flowchart showing the control operation of the control unit 49 related to water leak abnormality detection of the water purification apparatus 1. Hereinafter, with reference to FIG. 9, the control regarding the water leak abnormality detection of the water purification apparatus 1 is demonstrated. Here, the detection of water leakage abnormality is to detect that water leaking from the gas passage 16 may enter the ozone generator 21.

  During the purified water supply to the user shown in FIG. 8, when water of a predetermined level or more is accumulated in the water receiving chamber 74 and the water leak sensor 45 is turned on (Yes in step S11), the water leak sensor 45 is turned on. It is determined whether T2 seconds, for example, 1 second has elapsed (step S12). When T2 seconds elapse (Yes in step S12), the pump 5 and the ozone generator 21 are turned off (step S13), the abnormal LED 60 is turned on, the ozone LED 59 blinks (step S14), and water supply to the user is performed. Stopped.

  When the user wants to use the purified water again after the water supply is stopped, the water purification apparatus 1 can be restarted by turning the power switch 56 ON again. At this time, the water leak sensor 45 is reset to the initial state. That is, even when the water supply is stopped while the water leak sensor 45 is ON, after the restart, it is reset to the OFF state. If water of a predetermined water level or more remains in the water receiving chamber 74 even after the water supply is stopped, the above processing and determination (steps S11 to 14) are performed again immediately after the restart, and the water supply is stopped.

  Thus, by stopping the pump 5 and the ozone generator 21 according to the detection of the water leak sensor 45, it is possible to prevent electric leakage and electric shock, and to operate the water purification apparatus 1 safely. Can do.

  At the same time, since the user is notified of the abnormality by turning on the abnormality LED 60 or blinking the ozone LED 59, the user can quickly cope with the water leakage abnormality detection. Further, if the water level in the water receiving chamber 74 is less than a predetermined water level (for example, the height of the broken line in FIG. 5A), the water leak sensor 45 does not detect that the water leak is abnormal, and further the water leak sensor. Even when 45 is turned on, if T2 seconds have not elapsed (No in step S12), the water leakage abnormality detection is not performed. Therefore, it is possible to prevent the user from being forced to deal with an unnecessary water leakage abnormality, and the water purification process can be performed efficiently.

  As described above, in this water purification device 1, even when the water in the water flow path 14 leaks from the inlet 19, the water flows from the inlet 19 to the ozone generator 21 side at the three-way branch 18. The water is drained from the drainage port 34 through the drainage pipe 35 without entering. As described above, since it is possible to prevent water from entering the ozone generator 21, it is possible to prevent the ozone generator 21 from being exposed to water and being unable to discharge, and to stably supply ozone. it can. That is, it is possible to prevent a reduction in water quality improvement efficiency (ozone mixing efficiency).

  Further, during the ozone supply to the inlet 19, the drain pipe 35 is shut off from the outside through the drain valve 36, and external air flows into the gas passage 16 from the drain pipe 35 through the three-way branch 18. Therefore, the concentration of the supplied ozone can be prevented from being lowered, and a constant concentration of ozone can be stably supplied. As a result, water can be efficiently purified.

Furthermore, since the pump 5 and the ozone generator 21 are stopped by detecting the water leakage abnormality by the water leakage sensor 45, it is possible to prevent electrical leakage and electric shock and to operate the water purification device 1 safely. .
<Modification 1>
(Configuration of water purification device 1)
FIG. 10 is a schematic perspective view of the water purification apparatus 1 according to the first modification of the present invention. FIG. 11 is a system diagram illustrating a configuration example of the water purification device 1 according to the first modification. In addition, about the part which overlaps with FIG. 1 and FIG. 2, the same code | symbol is attached | subjected and the description is abbreviate | omitted. In the system diagram of FIG. 11, the solid line arrows represent the flow of water, and the broken line arrows represent the flow of electricity.

  Referring mainly to FIG. 11, the water purification apparatus 1 according to the first modification is not provided with the pump 5 and the pressure sensor 11 as shown in FIG. 2, and the raw water supply pipe 6 is connected to the raw water supply pipe. An opening / closing valve 61 for opening / closing 6 is provided.

  The open / close valve 61 is, for example, a valve such as an electromagnetic valve that is electrically opened and closed, and is electrically connected to the control unit 49. Therefore, the user can use purified water by connecting the raw water supply pipe 6 to, for example, a faucet or the like and opening and closing the opening / closing valve 61 as appropriate. In addition, the purified water supplied to a user is produced | generated by the method similar to the said Example 1. FIG.

  FIG. 12 is a schematic plan view of the operation display unit 55 of the water purification device 1 according to the first modification. FIG. 13 is a block diagram illustrating an electrical configuration of the water purification apparatus 1 according to the first modification, and illustrates a portion related to the first modification. In addition, about the part which overlaps with FIG. 7, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  The control unit 49 of the water purification device 1 according to the first modification is configured with, for example, a microcomputer. The control unit 49 is electrically connected to the operation display unit 55, the ozone generator 21, the open / close valve 61, and the water leak sensor 45, respectively.

In addition to the power switch 56, the power LED 58, the ozone LED 59, and the abnormality LED 60, the operation display unit 55 opens and closes a course switch 62 for selecting whether ozone is mixed in the water to be supplied, and an opening / closing valve 61. A water supply switch 63 and a water supply LED 64 for displaying whether or not the water supply is in progress are provided. Therefore, the user can open and close the open / close valve 61 to supply water by operating the operation display unit 55, or can generate purified water by mixing ozone into the supplied water.
(Control of water purification device 1)
FIG. 14 is a flowchart showing a control operation of the control unit 49 related to the purified water supply of the water purification apparatus 1 according to the first modification. Hereinafter, with reference to FIG. 14, the control regarding the purification water supply of the water purification apparatus 1 which concerns on the modification 1 is demonstrated.

  When the power switch 56 is turned on by the user (step S21), the course setting is read from the ROM 52 (step S22). Here, the course setting is, for example, program contents in which the amount of ozone supplied to the water being supplied is set, and the user can change the course setting by appropriately changing the contents of the ROM 52. it can. When the course switch 62 is turned on (Yes in step S23), the ozone generator 21 is turned on (step S24).

  Then, when the water supply switch 63 is turned on (step S25) and water supply is started by opening the opening / closing valve 61 (step S26), ozone is supplied to the ozone mixer 7 by negative pressure. At this time, water supply is started even when the water supply switch 63 is turned on without the course switch 62 being turned on (No in step S23). At this time, water not mixed with ozone is sent to the user use side. Further, even when the user starts water supply without turning on the course switch 62, the user can supply ozone to the ozone mixer 7 by turning on the course switch 62 during water supply. Thereafter, when the power switch 56 is turned off (step S27), the purified water supply ends.

  Thus, if the open / close valve 61 is provided in the raw water supply pipe 6 and the user can appropriately supply purified water by operating it appropriately, for example, a water source (for example, a well, a river, etc.) and the user's Even if the place of use is remote, if the pump is driven near the water source and the opening / closing valve 61 is provided near the place of use of the user, there is no need to drive the pump, etc. every time it is used. The purified water can be used simply by operating the on-off valve 61 according to the time of use.

  Further, since the pump 5 is not driven by the pressure sensor 11 as in the first embodiment, there is no need to provide a flow opening / closing component such as a faucet on the user side. In other words, the water purification apparatus 1 according to the first modified example is used to purify the water regardless of the situation (for example, the presence or absence of a faucet) where the ends of the raw water supply pipe 6 and the purified water supply pipe 9 communicate. Can be used.

In addition, about the control of the water leak abnormality detection of the water purification apparatus 1 which concerns on this modification 1, since it is the same as that of Example 1, description is abbreviate | omitted here.
<Modification 2>
(Configuration of water purification device 1)
FIG. 15 is a system diagram illustrating a configuration example of the water purification device 1 according to the second modification. In addition, about the part which overlaps with FIG. 1 and FIG. 2, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the water purification apparatus 1 according to the second modification, the water source 3 shown in FIG. 2 is a tank 65 as a water storage tank for storing water.

  The tank 65 is installed on the same height as the roof of the house 77, for example, by building a dedicated steel tower. A water storage pipe 69 including a tank pump 66 for pumping water from a water source (for example, a well or a river) is connected to the tank 65, and water is supplied into the tank 65 by the driving force of the tank pump 66. Is accumulated.

  In addition, the pump 5 is installed at a position lower than the tank 65, more specifically, on the floor 78 of the house 77, and the casing 27 is installed on the inner wall 79 of the house 77. The pump 5 and the casing 27 (more specifically, Specifically, the ozone mixer 7 (see FIG. 1) is connected by a raw water supply pipe 6.

  A suction pipe 4 extending downward from the inside of the tank 65 is connected to the pump 5, and a purified water supply pipe 9 as a return path is connected to the casing 27 (more specifically, the ozone mixer 7 (see FIG. 1)). The other end of the purified water supply pipe 9 is connected to the inside of the tank 65 from above the tank 65.

  Therefore, the water in the tank 65 is a path (circulation flow path) of the tank 65 → the suction pipe 4 → the pump 5 → the raw water supply pipe 6 → the casing 27 → the purified water supply pipe 9 → the tank 65 by the driving force of the pump 5. ) Is circulated while being purified in the housing 27. Thus, since the water in the tank 65 is purified and circulated, the purified water can be stored in the tank 65. Moreover, since the pump 5 and the housing | casing 27 are each installed in the low position of the floor 78 and the inner wall 79, the user can perform operation operation and maintenance of the water purification apparatus 1 easily.

  The tank 65 is connected to one end of a user water supply pipe 67 that extends downward from the tank 65, bends in the middle, and extends into the house 77. A faucet 68 is provided at the other end of the user water supply pipe 67. It has been. Therefore, when the user uses water, for example, it is not necessary to provide a special device such as a pumping pump, and the user can use the water in the tank 65 only by a simple operation of opening the tap 68.

  Furthermore, when this water purification apparatus 1 is operated with solar energy, purified water is produced within daylight hours and is prepared for use at night.

In the second modification, the tank 65 is installed on a dedicated steel tower or the like, but may be installed on the roof of the house 77, for example. The water stored in the tank 65 is not limited to the water pumped up from the water source by the tank pump 66, and for example, rainwater can be stored in the tank 65. Furthermore, although the tank 65 is given as an example, if the water storage pipe 69 and the user water supply pipe 67 are omitted and the tank 65 is replaced with, for example, a pool or a bathtub, the tank 65 is stored in the pool or the bathtub. Since germs and the like contained in the water can be removed by purification circulation, clean water can be stored without periodically replacing the water.
<Modification 3>
FIG. 16 is a system diagram illustrating a configuration example of an ozone water generation apparatus 70 according to the third modification. In addition, about the part which overlaps with FIG. 1 and FIG. 2, the same code | symbol is attached | subjected and the description is abbreviate | omitted. In the system diagram of FIG. 16, solid arrows indicate the flow of water, and broken arrows indicate the flow of electricity.

  The ozone water generator 70 according to the third modification includes a tank 65 for storing tap water, a pump 5 for sucking water stored in the tank 65 through the suction pipe 4, and discharged from the pump 5 to produce raw water. A water ozone mixing device 2 for mixing ozone with water sent through the water supply pipe 6 and a purified water supply pipe 9 for releasing ozone water generated by the water ozone mixing device 2 are provided. In the present invention, the purified water supply pipe 9 corresponds to an ozone water output pipe.

  More specifically, the water source 3 of the water purification apparatus 1 shown in FIG. 2 is replaced with a tank 65, and the ozone deodorizing column 10 is omitted. The tank 65 stores, for example, tap water. Therefore, the tap water stored in the tank 65 is mixed with ozone in the water ozone mixing device 2 and discharged from the purified water supply pipe 9 as ozone water having an excellent sterilizing / deodorizing function.

  In the water purification apparatus 1 shown in FIG. 2, the pump 5 is installed outside the housing 27. However, in the ozone water generation apparatus 70, the parts including the tank 65 and the pump 5 include, for example, the tire 71. It is accommodated in the attached movable casing 72, and the ends of the purified water supply pipe 9 and the intake pipe 22 are exposed from the movable casing 72. Therefore, when the user wants to use ozone water, the user can wash hands and feet with ozone water or water the ozone water by attaching a faucet or a shower nozzle to the end of the purified water supply pipe 9, for example. Can do.

Furthermore, when the movable casing 72 is used as described above, it can be easily carried. For example, after placing fresh fish on a loading platform such as a truck for transporting fresh fish, and then sprinkling water on the toro box that contains the fresh fish, the toro box can be disinfected, deodorized, or stripped. it can. In addition, the ozone water which a user uses is produced | generated by the method similar to the said Example 1. FIG.
<Modification 4>
FIG. 17 is a front perspective view of the housing 27 in the water purification apparatus 1 according to Modification 4. FIG. 18 is a front perspective view of the inside of the housing 27. FIG. 19 is a plan view of the inside of the housing 2. FIG. 20 shows a mode in which the ozone generator 21 is arranged above the control unit 49 in FIG.

  In the water purification apparatus 1 according to the modified example 4, as shown in FIG. 17, the casing 27 is long in the left-right direction and thin in the front-rear direction (the direction connecting the front side and the back side of the casing 27). The operation display unit 55 described above is arranged on the upper right side of the front. In the housing 27, the back portion on the back side is fixed to a wall or the like as an installation surface. The inlet 12 of the ozone mixer 7 is provided so as to protrude outward from the right side surface of the casing 27, and the outlet 13 of the ozone mixer 7 (see FIG. 18) is provided on the left side surface of the casing 27. A connection-side outlet 84 of a connection pipe 83 (described later) coupled to is provided so as to protrude outward from the left side surface of the housing 27.

  As shown in FIG. 18, the inside of the housing 27 is partitioned into a substantially rectangular parallelepiped shape, and a blocking wall 80 extending in the horizontal direction is provided at a substantially central position in the vertical direction. The blocking wall 80 is formed in a rectangular thin plate having a size substantially equal to the planar shape of the housing 27 in plan view, and the inside of the housing 27 is divided into two regions arranged in the vertical direction by the blocking wall 80. It is divided into. Hereinafter, of the two areas partitioned inside the casing 27, the upper area is referred to as an electrical component area 81, and the lower area is referred to as a water channel area 82.

  In the water channel region 82, the ozone mixer 7 and the connecting pipe 83 (collectively referred to as a water channel 87) are located on the front side of the casing 27 (that is, the front side, the lower side in FIG. 19) as shown in FIG. 19. Is arranged. The connecting pipe 83 is a circular pipe extending substantially horizontally in the left-right direction, and the above-described connecting-side outlet 84 is provided at the left end, and the connecting-side inlet 85 is provided at the right end. In the connection pipe 83, the connection side outlet 84 is connected to the purified water supply pipe 9 (see FIG. 2) outside the housing 27, and the connection side inlet 85 is connected to the outlet 13 of the ozone mixer 7. . Further, the inlet 12 of the ozone mixer 7 is connected to the raw water supply pipe 6 (see FIG. 2) outside the housing 27, and in this water channel 87, water flows from the right side to the left side.

  The water flow path 14 of the ozone mixer 7 is also formed so as to extend substantially horizontally in the left-right direction, like the connecting pipe 83. Therefore, the water channel 87 is formed so as to extend substantially horizontally in the left-right direction as a whole.

  In the ozone mixer 7, the check valve 17 and the drain valve 36 shown in FIG. 18 can be removed during maintenance.

  The electrical component region 81 is blocked from the water channel 87 by the blocking wall 80, and the ozone generator 21 and the control unit 49 described above are arranged on the back side (that is, the back side, FIG. 19) of the casing 27 as shown in FIG. On the upper side). Specifically, as shown in FIG. 18, in front view, the ozone generator 21 is disposed on the left side of the electrical component region 81, and the control unit 49 is arranged on the right side of the ozone generator 21, And it is arrange | positioned above the ozone mixer 7 on both sides of the shielding wall 80. FIG.

  The above-described ozone supply pipe 24 of the ozone generator 21 is made of a flexible material, specifically, Teflon (registered trademark) or silicon rubber having excellent durability against ozone degradation, The ozone generator 21 extends downward, passes through a through hole 91 formed in the blocking wall 80, and then extends obliquely downward to the right and is connected to the inlet 19 of the ozone mixer 7.

  As described above, in the fourth modification, the electrical components such as the ozone generator 21 and the control unit 49 are arranged in the electrical component region 81 defined above the water channel 87, so that even if water leaks from the water channel 87. There is no possibility that the leaked water reaches the ozone generator 21 and the control unit 49 by its own weight. Further, since the electrical component region 81 is blocked from the water channel 87 by the blocking wall 80, for example, even if water scatters from the water channel 87 during maintenance, the water is immersed in the ozone generator 21 and the control unit 49. This can be surely prevented.

  In particular, the blocking wall 80 is disposed above a portion where water leakage may occur, such as a coupling portion between the water channel 87 and the ozone mixer 7 (that is, the vicinity of the outlet 13 and the connection-side inlet 85). Inundation of the ozone generator 21 and the control unit 49 can be prevented more reliably. Further, as described above, in the ozone mixer 7, the check valve 17 and the drain valve 36 can be removed at the time of maintenance. Therefore, there is a coupling portion between these removable parts and the water channel 87. Exists. Although there is a possibility that water leakage may occur at these connecting portions, the blocking wall 80 is disposed above the check valve 17 and the drain valve 36, so that the ozone generator 21 and the controller 49 are more reliably submerged. Can be prevented. In addition, since the through hole 91 through which the ozone supply pipe 24 described above penetrates in the blocking wall 80 is located at a position away from the coupling portion described above, even if water leaks, water is electrically connected through the through hole 91. There is no risk of entering the product area 81.

  The water channel 87 extending substantially horizontally in the left-right direction in the housing 27 has no refracting portion. If there is a refracting portion, it is necessary to separately provide a connecting part such as an elbow tube. In this case, not only the number of parts increases, but also there is a risk of water leakage from the connecting part between the connecting part and the water channel 87. However, these fears are eliminated by the water channel 87 of the present invention, and the inundation of the ozone generator 21 and the control unit 49 can be more reliably prevented.

  In addition, the inlet 12 of the ozone mixer 7 forming one end of the water channel 87 protrudes outward from the right side surface of the housing 27, and is connected to the raw water supply pipe 6 (see FIG. 2) outside the housing 27. A connection-side outlet 84 of the connection pipe 83 that forms the other end of 87 protrudes outward from the left side surface of the housing 27, and is connected to the purified water supply pipe 9 (see FIG. 2) outside the housing 27. In this way, water leakage may occur at the inlet 12 and the connection-side outlet 84 that are connected to the raw water supply pipe 6 and the purified water supply pipe 9, but the inlet 12 and the connection-side outlet 84 are These are provided so as to protrude outward from the side surface of the casing 27, and are not located inside the casing 27. Therefore, even if water leakage occurs at the inlet 12 and the connection-side outlet 84, it is possible to more reliably prevent the ozone generator 21 and the controller 49 inside the casing 27 from being flooded.

  Further, the inlet 12 of the ozone mixer 7 is provided on the right side surface of the casing 27, and the connection side outlet 84 of the connecting pipe 83 is provided on the left side surface of the casing 27. 27 is supported on both left and right side surfaces, so that it can be stably placed in the casing 27, and the water channel 87 can be easily and assembled to the casing 27. The ozone mixer 7 has a boss portion 92 extending upward. The boss portion 92 is fixed to the blocking wall 80 with a screw or the like, so that the ozone mixer 7 is also attached to the blocking wall 80. It is supported (see FIG. 18).

  Further, since the inlet 12 of the ozone mixer 7 is coupled to the water channel 87 so as to constitute one end of the water channel 87, compared with the case where the ozone mixer 7 is coupled in the middle of the water channel 87, the ozone mixing is performed. The joint portion between the vessel 7 and the water channel 87, that is, the portion where water leakage may occur can be reduced, and the ozone generator 21 and the controller 49 can be more reliably prevented from being flooded. In order to achieve the same effect, the outlet 13 of the ozone mixer 7 may constitute the other end of the water channel 87 (that is, the connection side outlet 84 in FIG. 18). In this case, the water pipe 14 of the ozone mixer 7 is extended so that the connecting pipe 83 is omitted and the outlet 13 protrudes outward from the left side surface of the casing 27. Of course, if the water channel 14 of the ozone mixer 7 constitutes the water channel 87 itself, the above-described connecting portion can be eliminated, and the ozone generator 21 and the controller 49 can be more reliably prevented from being flooded. .

  Further, the electrical components such as the ozone generator 21 and the control unit 49 are arranged on the back side (that is, the back side, the upper side in FIG. 19) of the casing 27 as shown in FIG. It is desirable. On the other hand, the water channel 87 is arranged on the front side (that is, the front side, the lower side in FIG. 19), so that maintenance can be easily performed. In addition, due to such an arrangement relationship, there is a gap between the ozone generator 21 and the control unit 49 arranged on the back side and the water channel 87 arranged on the near side, so that water leaked from the water channel 87. However, it is possible to reliably prevent the ozone generator 21 and the controller 49 from being flooded.

  Moreover, when the ozone generator 21 is arrange | positioned above the ozone mixer 7, the space | interval of the ozone generator 21 and the ozone mixer 7 becomes comparatively narrow. In this case, the ozone supply pipe 24 cannot be connected between the ozone generator 21 and the ozone mixer 7 with an appropriate curvature, and is bent unnaturally on the way. There is a risk that the mixer 7 cannot be supplied smoothly. However, in the present invention, as shown in FIG. 18, the control unit 49 is arranged above the ozone mixer 7, and the ozone generator 21 is arranged on the left side of the control unit 49. . Thereby, since the space | interval of the ozone generator 21 and the ozone mixer 7 can be made comparatively wide, the ozone supply pipe 24 connects between the ozone generator 21 and the ozone mixer 7 with an appropriate curvature. The ozone from the ozone generator 21 can be smoothly supplied to the ozone mixer 7.

  Further, the water in the water channel 87 (specifically, the water channel 14) that has entered the gas passage 16 from the outlet 20 of the ozone mixer 7 shown in FIG. 3 reaches the inlet 19 located below the outlet 20 by its own weight. As shown in FIG. 18, the inlet 19 is connected to the ozone supply pipe 24 obliquely upward. Therefore, there is no possibility that water that has entered the gas passage 16 reaches the ozone generator 21 via the inlet 19 and the ozone supply pipe 24. Therefore, the ozone generator 21 can be reliably prevented from entering the water, and the water that has entered the gas passage 16 can be reliably drained by the drain pipe 35 shown in FIG.

Further, as shown in FIG. 18, in the electrical component region 81, the ozone generator 21 and the control unit 49 are arranged in the left-right direction, but instead of this, as shown in FIG. The device 21 may be disposed above the control unit 49. The ozone generator 21 needs to take measures against flooding more than other electrical components. However, the ozone generator 21 is arranged above the control unit 49 so as to be further separated from the water channel 87. Infiltration of water can be prevented more reliably. Furthermore, since the casing 27 can be made smaller (narrower) in the left-right direction than the configuration in FIG. 18, the water channel 87 can be configured only by the ozone mixer 7.
<Modification 5>
FIG. 21 is a front perspective view of the water purification device 1 according to the fifth modification.

  As shown in FIG. 21, in the water purification apparatus 1 according to the modified example 5, the above-described purification apparatus (housing 27) is arranged inside a lattice-shaped frame 90 that is a rectangular parallelepiped that is long in the vertical direction. The operation display unit 55, the ozone generator 21, the ozone mixer 7 and the control unit 49), the suction pipe 4, the pump 5, and the raw water supply pipe 6 arranged in the casing 27 are assembled. Note that the housing 27 and the internal structure of the housing 27 according to Modification 5 are the same as those shown in Modification 4. And in FIG. 21, the ozone generator 21, the ozone mixer 7, and the control part 49 are not illustrated (refer FIG. 18).

  The casing 27 is disposed at the upper end on the front side of the frame 90. The pump 5 is disposed at a lower position than the casing 27, specifically, at the lower right end of the frame 90. In addition, the pressure sensor 11 described above is disposed adjacent to the upper left side of the pump 5.

  The raw water supply pipe 6 extends leftward from the pump 5 while winding a clockwise spiral three times in the right side view. Each spiral portion of the raw water supply pipe 6 is formed in a substantially rectangular shape that is long in the vertical direction when viewed from the right side, and a cylindrical filter 89 that is long in the vertical direction is provided at the back side of each spiral portion. It is inserted one by one. That is, in the raw water supply pipe 6, the three filters 89 are arranged in series. Here, the pressure sensor 11 described above detects the pressure of water flowing from the pump 5 to the filter 89 located at the right end in the frame 90. And the pressure value which the pressure sensor 11 detects is given to the control part 49 mentioned above.

  The raw water supply pipe 6 extends downward from the filter 89 located at the left end in the frame 90, refracts and extends upward, and is connected to the water channel 87 of the housing 27. A manual valve 88 is inserted in the vicinity of the portion connected to the water channel 87 of the raw water supply pipe 6. By manually opening and closing the manual valve 88, the raw water supply pipe 6 can be opened or shut off. The manual valve 88 is also inserted in the vicinity of the pressure sensor 11 of the raw water supply pipe 6.

  Although not shown, the tank 65 shown in the modified examples 2 and 3 is disposed above the frame 90, and the suction pipe 4 extends downward from the tank 65 and is connected to the pump 5. . The casing 27 described above is adjacent to the tank 65 below.

  In the water purification apparatus 1, the water stored in the tank 65 flows downward in the suction pipe 4 and is then sucked into the pump 5 and discharged to the raw water supply pipe 6. Thereafter, the water flows spirally in the raw water supply pipe 6 along the shape of the raw water supply pipe 6 and further flows to the left side while removing foreign matters (iron, manganese components, etc.) by the filter 89, and the casing 27 The waterway 87 is reached. As shown in FIG. 18, the water that has reached the water channel 87 is purified by being mixed with ozone by the ozone mixer 7, and then the purified water supply pipe 9 connected to the water channel 87 (see FIGS. 2, 15, and 16). ) And supplied to the user use side as described above.

  Thus, in the water purification apparatus 1 according to the modified example 5, as shown in FIG. 21, the purification apparatus (the casing 27, the operation display unit 55 arranged in the casing 27, the ozone generator 21, the ozone mixer). 7 and the control unit 49) are disposed as close as possible to the tank 65 as described above, so that the height difference between the purification device and the tank 65 can be reduced, and the water stored in the tank 65 is supplied to the purification device. The loss of the head when it reaches can be suppressed. Thereby, since the pressure loss of the water which flows through the ozone mixer 7 of a purification apparatus can be prevented, the fall of the suction | inhalation flow rate of ozone to the ozone mixer 7 is suppressed, and the fall of the efficiency of gas-liquid mixing is prevented. be able to. Therefore, the water purification device 1 can improve the water quality satisfactorily with a simple configuration.

  Moreover, generally the pump 5 which is a heavy article is arrange | positioned in the position lower than a purification apparatus, Therefore The attitude | position of the water purification apparatus 1 can be stabilized.

  Further, since the water in which the foreign matter is captured by the filter 89 is introduced into the purification device, it is possible to prevent the foreign matter from being clogged in a portion where water flows inside the purification device, such as the ozone mixer 7.

  And since this filter 89 is provided in the middle of the raw | natural water feed pipe 6, it is arrange | positioned upstream from the purification | cleaning apparatus seeing in the flow direction of water. In general, when water passes through the filter 89, the filter 89 becomes a resistance, so that pressure loss occurs in water near the filter 89. Therefore, when the filter 89 is disposed downstream of the purification device, the pressure loss described above occurs on the downstream side of the purification device, and there is a concern that the ozone suction flow rate to the ozone mixer 7 may be reduced. . However, in the present invention, since the filter 89 is disposed on the upstream side of the purification device, a decrease in the ozone suction flow rate to the ozone mixer 7 is suppressed, and the above-described decrease in the efficiency of gas-liquid mixing is prevented. be able to. Thereby, in this water purification apparatus 1, water quality can be satisfactorily improved with a simple configuration.

  Further, as described above, the pressure sensor 11 detects the pressure of water flowing from the pump 5 to the filter 89 located at the right end in the frame 90, and this pressure value is determined by the control unit 49 described above. Given to. Since the pressure value increases when the filter 89 is clogged, the control unit 49 determines that the filter 89 is clogged when the pressure value detected by the pressure sensor 11 rises to a predetermined value. When the control unit 49 determines that the filter 89 is clogged, a filter clogging LED (not shown) provided in the control display unit 55 is turned on to notify the user of the clogging of the filter 89. Here, the control display unit 55 functions as a notification unit. In addition, it may replace with filter clogging LED (not shown) and may alert | report with a sound with a buzzer etc.

  That is, when the filter 89 is clogged, the flow of water in the raw water supply pipe 6 and the purification device is deteriorated, so that the flow rate of the ozone mixed into the water in the ozone mixer 7 is reduced to the ozone mixer 7. Is concerned. However, in the present invention, the pressure sensor 11 can manage the clogged state of the filter 89 by detecting the pressure of the water flowing between the pump 5 and the filter 89. And the control part 49 judges clogging of the filter 89 according to the value of the pressure detected by the pressure sensor 11, and the control display part 55 notifies clogging of the filter 89 according to the judgment, Since the filter 89 can be prevented from being accidentally clogged, the above-described decrease in the ozone suction flow rate can be suppressed, and the decrease in gas-liquid mixing efficiency can be prevented.

  Further, as the tank 65 is arranged at a higher position, as described above, there is a concern that the ozone suction flow rate into the ozone mixer 7 is reduced. If the filter 89 is clogged there, there is a concern that the ozone suction flow rate into the ozone mixer 7 may further decrease. Therefore, in order to prevent a decrease in the suction flow rate of ozone due to clogging of the filter 89, it is desirable to detect clogging of the filter 89 as soon as possible, but the pump 5 is disposed at a position lower than the tank 65. In the configuration, the higher the tank 65 is arranged, the higher the pressure value is detected by the pressure sensor 11. Therefore, the clogging of the filter 89 is determined earlier than the actual and is notified to the user. Thereby, it is possible to prevent a decrease in the suction flow rate of ozone into the ozone mixer 7 due to the filter 89 being clogged.

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims. For example, the configuration of the water ozone mixing device 2, the water purification device 1, or the ozone water generating device 70 according to the present invention may be used for a bath water purification process in a washing machine that performs washing using bath water. it can.
