It is the perspective view which illustrated 2nd Embodiment of the flush toilet bowl of this invention.

  FIG. 1 is a longitudinal sectional view illustrating a first embodiment of a flush toilet according to the present invention. In FIG. 1, an ozone generator, a water supply unit, an ozone water supply path, and the like are shown in a simplified manner.

The flush toilet 1 includes a bowl 2, a toilet seat 3, a toilet seat cover 4, a supply unit 5, an ozone water generator 6, and an ozone water supply path 8.

  Examples of the material of the bowl 2 include pottery and resin. The bowl 2 has a trap 2b that bends and extends rearward from the opening 2a, and water for forming an air trap can be retained in the opening 2a by the trap 2b. Further, a rim 2c is formed at the upper end edge of the opening 2a of the bowl 2, and a placement surface 2d on which the water storage tank 51 can be placed is formed behind the opening 2a of the bowl 2.

  The toilet seat 3 can be opened and closed up and down above the opening 2a of the bowl 2. When the toilet seat 3 is closed, the toilet seat 3 and the rim 2c of the bowl 2 come into contact with each other. The toilet seat cover 4 is openable and closable on the toilet seat 3.

  The supply unit 5 includes a water supply unit 7, a water storage tank 51, and a supply pipe 52.

  The water storage tank 51 is mounted on the mounting surface 2d of the bowl 2 and can store a predetermined amount of water therein.

  The supply pipe 52 is connected to the water storage tank 51 and supplies bowl wash water to the bowl 2. Specifically, the supply pipe 52 is attached to the bowl 2 with the intake port 52a at the upstream end thereof disposed at the bottom of the water storage tank 51, and the discharge port 52b at the downstream end of the supply pipe 52 is connected to the bowl 2 It is directed in the direction of the rim 2c. Therefore, the water in the water storage tank 51 is discharged along the rim 2c from the discharge port 52b of the supply pipe 52 as the bowl cleaning water (in the direction of arrow F in FIG. 1) and supplied into the bowl 2.

  The water supply unit 7 includes a water supply pipe 7a, an electromagnetic valve 7b, a check valve 7c, a vacuum breaker 7d, and the like. Further, the water supply pipe 7 a is branched downstream into a first flow path 7 e connected to the water storage tank 51 and a second flow path 7 f connected to the ozone generator 6 in the water storage tank 51. Water (tap water) passing through the water supply unit 7 is supplied to the water storage tank 51 through the first flow path 7e, and water (tap water) is supplied to the ozone water generator 6 through the second flow path 7f.

  The ozone water generator 6 is disposed in the water storage tank 51 of the supply unit 5. Specifically, for example, as illustrated in the schematic cross-sectional view of FIG. 2, the ozone water generating device 6 has a configuration having an inlet 61, an outlet 62, an ozone generator 63, a melting portion 64, and a heat transfer member 65. It can be illustrated. In the ozone water generating device 6 of FIG. 2, the water (tap water) supplied from the water supply unit 7 flows into the ozone water generating device 6 through the inlet 61 and is electrolyzed by the ozone generator 63 to generate ozone gas. generate. The ozone gas is dissolved in water in the dissolving part 64 to generate ozone water, and is stored in the dissolving part 64. The ozone water stored in the dissolving part 64 flows out from the outlet 62 to the ozone water supply path 8.

  The specific configuration of the ozone generator 63 is not particularly limited, and an electrolytic system that generates ozone gas by electrolyzing water via the electrode 63a (anode, cathode) can be appropriately employed. More specifically, for example, the ozone generator 63 may be one having a structure in which an electrode 63a (anode and cathode) connected to the power source E is partitioned by an ion exchange membrane M. As such an ion exchange membrane M, a well-known material having ozone resistance can be appropriately adopted. Specifically, for example, a material based on polytetrafluoroethylene or the like can be exemplified. . The anode and the cathode can be used in combination with appropriate materials suitable for the generation of ozone water. Specifically, examples of the anode material include diamond, gold, and platinum, and examples of the cathode material include diamond, stainless steel, gold, silver, platinum, and titanium. Among these, a diamond electrode is particularly preferable because it can suppress generation of hydrogen and oxygen generated by electrolysis and can efficiently generate ozone water.

  Further, the heat transfer member 65 is capable of transferring the heat of the electrode 63 a to the bowl washing water stored in the water storage tank 51. The material of the heat transfer member 65 is not particularly limited as long as the heat from the electrode 63a can be transferred to the bowl washing water in the supply unit. For example, the surface is filled with metal or metal powder. The resin molded product etc. which were done can be illustrated. The arrangement position of the heat transfer member 65 is preferably a position in contact with the electrode 63a, and can be disposed, for example, between the wall surface 6a of the ozone water generating device 6 and the electrode 63a. Thereby, the heat of the electrode 63a can be efficiently transmitted to the bowl washing water in the water storage tank 51.

  The ozone water supply channel 8 is a channel for supplying the ozone water stored in the ozone water generator 6 to the bowl 2. Specifically, the ozone water supply path 8 is connected to the outlet 62 of the ozone water generator 6 and the outlet 52 b of the supply pipe 52. Accordingly, the ozone water stored in the dissolving part 64 of the ozone water generating device 6 flows to the discharge port 52b of the supply pipe 52 through the ozone water supply path 8, merges with the water from the water storage tank 51, and has a predetermined ozone concentration. Of ozone water can be supplied to the bowl 2 as bowl washing water. The ozone water from the ozone water generator 6 can be directly supplied to the bowl 2 from the supply pipe 52 without joining the water from the water storage tank 51.

In the flush toilet 1, when the ozone water is generated by the ozone water generator 6, the electrode 63 a is heated by the current supplied from the power source E, and thus the temperature of the electrode 63 a is temporarily increased. However, since heat can be discharged to the water in the water storage tank 51 through the heat transfer member 65 provided in contact with the electrode 63a, the temperature of the ozone water in the dissolution part 64 is suppressed from becoming high. Is done. Accordingly, since the decrease in the solubility of ozone in ozone water is suppressed and ozone is difficult to vaporize, ozone water with a high concentration (for example, about 0.5 mg / L to 1.5 mg / L) can be reliably supplied to the bowl 2. it can. Thereby, the growth of microorganisms and the generation of malodor on the surface of the bowl 2 can be effectively suppressed.
When the bowl 2 is washed with the bowl washing water, for example, after the water in the water storage tank 51 is supplied to the bowl 2 and washed, the bowl washing water in the supply pipe 52 is supplied to the bowl washing water from the ozone water generator 6. Washing and sterilization can be performed by supplying ozone water to the bowl 2 after joining the ozone water.

Further, the flush toilet 1 includes a local washing water tank (not shown) that supplies the local washing water to the local washing nozzle 9 as the supply unit 5. The local cleaning nozzle 9 is connected to the local cleaning water tank of the supply unit 5 and can eject water upward from the vicinity of the tip. Further, the local washing water tank is provided in contact with the ozone water generating device 6 and is formed so that heat can be exchanged between the local washing water tank and the ozone water generating device 6. The specific configuration of the local cleaning nozzle 9 is not limited, and a nozzle having a conventionally known structure can be appropriately employed. The local cleaning nozzle 9 detects, for example, a state in which the user is seated on the toilet seat 3, slides forward (to the center side of the bowl 2), and ejects local cleaning water toward the local area of the user. It may be. Further, the local cleaning nozzle 9 can be connected to the ozone water generating device 6.

  In the flush toilet 1, when the ozone water is generated by the ozone water generator 6, the electrode 63 a is heated by the current supplied from the power source E, and thus the temperature of the electrode 63 a is temporarily increased. However, since the heat of the electrode 63a is discharged to the water in the local washing water tank (local washing water) through the heat transfer member 65, the temperature of the ozone water in the dissolving part 64 of the ozone water generating device 6 is increased. High temperature is suppressed. Accordingly, a decrease in the solubility of ozone in ozone water is suppressed, and ozone is difficult to vaporize, so ozone water having a high concentration (for example, about 0.5 mg / L to 1.5 mg / L) is stored in the dissolving portion 64. The high-concentration ozone water stored in the dissolving part 64 can be supplied to the bowl 2 via the supply pipe 52 of the supply part 5. Further, when the local cleaning nozzle 9 and the ozone water generating device 6 are connected, high-concentration ozone water stored in the dissolving unit 64 can be supplied to the local cleaning nozzle 9.

Thereby, the growth of microorganisms and the generation of malodor on the surface of the bowl 2 can be effectively suppressed. Furthermore, when the ozone water of the ozone water production | generation apparatus 6 is supplied to the local washing nozzle 9, the proliferation of microorganisms and generation | occurrence | production of a bad smell in the surface etc. of the local washing nozzle 9 can be suppressed effectively.

  Thus, in the flush toilet 1 of 2nd Embodiment, the heat | fever from the electrode 63a can be discharged | emitted by the water in the supply part 5 (local washing water tank) utilized as local washing water.

  The flush toilet of the present invention is not limited to the above embodiment. For example, a sudden pressure changing portion, a circulation flow path, and the like can be provided inside the supply portion and the water storage tank. For example, an electromagnetic valve can be provided in the supply portion. Further, in the first embodiment, the bowl cleaning using the water in the water storage tank has been described. However, the present invention can be applied to a so-called tankless flush toilet connected directly to a water pipe. In this case, for example, an ozone water generator is provided so as to be in contact with the supply unit (supply pipe) directly connected to the water pipe, and the heat generated at the electrode is transferred to the bowl washing water in the supply unit (supply pipe) and discharged. By doing, it can suppress that the temperature of the ozone water in a melt | dissolution part becomes high temperature. Also, an ozone water generator is provided so as to be in contact with a supply part (supply pipe) that supplies tap water to the local wash water tank, and heat generated at the electrode is transferred to the local wash water in the supply part (supply pipe). You may make it discharge | emit. In addition, an ozone water generator is installed to contact both the supply part (supply pipe) for supplying bowl wash water to the bowl and the supply part (supply pipe) for supplying tap water to the local wash water tank, and is generated at the electrodes. The heated heat may be transferred to both the bowl washing water and the local washing water and discharged.

  Moreover, in the flush toilet of this invention, the heat-transfer member of an ozone water production | generation apparatus is not necessarily required, and the heat | fever of an electrode can also be discharged | emitted via the water stored in the ozone water production | generation apparatus. In this case, the water from which the heat of the electrode has been discharged can be supplied to the bowl through, for example, a supply unit.
