  An object of this invention is to provide the toilet equipment on which the bactericidal effect by a metal ion and the effect | action by light irradiation were superimposed.

  The toilet equipment according to claim 1, wherein the toilet equipment includes a nozzle for discharging water and metal ion addition means for adding metal ions to water supplied to the nozzle. A light-emitting body for irradiating is provided.

  The toilet facility according to claim 2 is characterized in that, in claim 1, the light emitter is provided so as to irradiate light from a tip portion of the nozzle.

  The toilet equipment according to claim 3 is characterized in that, in claim 2, the light emitter is provided in the nozzle or upstream of the nozzle.

  A toilet facility according to a fourth aspect of the present invention is characterized in that, in any one of the first to third aspects, the nozzle is a nozzle for washing a human body.

  The toilet equipment according to claim 5 is characterized in that, in any one of claims 1 to 3, the nozzle is a nozzle for washing a toilet bowl, a toilet seat or a toilet lid.

  If water containing metal ions such as silver ions hits the buttocks of the human body, a bactericidal action can be obtained. This metal ion is activated by light. This activation action becomes stronger as the light has a shorter wavelength. Moreover, if this water hits a toilet bowl etc., the surface, a downstream trap, a drain pipe, etc. can be cleaned.

  In this invention, since light is irradiated, if this light is an ultraviolet-ray (UV), a bactericidal effect can be acquired by it. If a photocatalyst is provided in a toilet bowl or the like, an antifouling effect can be obtained by the photocatalytic action even if the light is not UV.

  When light is emitted from the nozzle, the shadow area is reduced. When the illuminant is provided in the nozzle or upstream of the nozzle, light can be guided to the water ejected from the nozzle, and the photocatalytic action and the sterilization action of the metal ions can be exerted on the contact area of the water.

  According to the present invention, the toilet bowl, toilet seat, and toilet lid can be efficiently and antifouling or sterilized by the above-described action.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall longitudinal sectional view showing a toilet facility according to the embodiment, and FIG. 2 is a sectional view showing a nozzle of a hot water cleaning apparatus.

  In FIG. 1, a trap 14 is provided at the bottom of the toilet bowl 12 of the Western-style toilet 10, and a drain port 16 is provided following the trap 14. Water in the raw tank 20 is supplied to the toilet bowl 12 through a water channel 18.

  A toilet seat box 22 is installed on the rear upper surface of the western-style toilet 10, and a toilet seat 24 and a toilet lid 26 are attached to the toilet seat box 22 so as to be rotatable in the vertical direction. A coating layer of a photocatalyst is provided on the inner surface of the toilet bowl 12, the lower surface, the upper surface, the inner peripheral surface and the outer peripheral surface of the toilet seat 24, and the lower surface of the toilet lid 26 and the toilet seat box 22, respectively.

  In the toilet seat box 22, in addition to the nozzle 30 for washing the toilet user's buttocks with warm water, a hot water tank for the nozzle 30 and a warm air fan for drying the buttocks are installed. In this embodiment, an electrolyzer for adding silver ions to the water supplied to the nozzle is also installed in the toilet seat box 22.

  The nozzle 30 includes a cylinder 32, a nozzle body 34 that can be advanced forward from the cylinder 32, a jet port 36 at the tip of the nozzle body 34, a UVLED 38 provided at the rear of the cylinder 32, and the nozzle body 34. A return spring or the like that biases in the backward direction is included. A reflection surface 34 a for reflecting the ultraviolet rays from the UVLED 38 toward the jet port 36 is provided at the tip portion in the nozzle body 34. A photocatalyst coating layer is provided on the outer and inner surfaces of the nozzle body 34 and the cylinder 32.

  The nozzle 30 is supported by a nozzle support device 50. The nozzle support device 50 can change the direction of the nozzle 30 up, down, left, and right, and rotates the nozzle 30 about its axis, so that the direction of water ejection from the ejection port 36a is not only upward but also laterally. , Diagonally upward, diagonally downward, and downward.

  In the toilet equipment configured as described above, when the human buttock is washed with warm water by the nozzle 30, the jet port 36 of the nozzle 30 is set in an upward state, hot water is supplied to the cylinder 32, and the nozzle body 34 as shown in FIG. The hot water is jetted upward from the jet nozzle 36. At this time, when the silver ion adding means is operated, the heel part is washed with warm water containing silver ions, and silver ion sterilization is performed. At the time of cleaning the buttock, the UVLED 38 may be turned on, and the ultraviolet rays reflected by the reflecting surface 34a may be applied to the buttock to be sterilized by ultraviolet rays. In addition, silver ion is activated by UV and a bactericidal action is strengthened.

  As described above, when ultraviolet rays are applied to the human body, the wavelength of the ultraviolet rays is preferably about 340 to 380 nm. When the hot water supply is stopped, the nozzle body 34 moves backward by the urging force of the return spring. When the nozzle body 34 is in the retracted state, it is desirable that the UV LED 38 is turned off.

  In the case of irradiating UV light from the UVLED 38 to the inner surface of the toilet bowl 12, etc., first, the nozzle 30 is rotated so that the outlet of the nozzle 30 faces downward, and then hot water is supplied to the nozzle 30 to advance the nozzle body 34. In addition, the UVLED 38 is energized. Ultraviolet rays from the UV LED 38 are reflected by the reflecting surface 34 a and are irradiated to the outside from the ejection port 36. Thereby, ultraviolet rays are directly applied to the lower surface of the inner surface of the toilet bowl 12. In addition, the toilet bowl 26 and the toilet seat 24 are irradiated with ultraviolet rays reflected from the surface of the water reservoir and the inner surface of the toilet bowl 12. This ultraviolet irradiation provides a bactericidal action, excites the photocatalyst, and produces an organic matter decomposing action (antifouling action). Further, the sterilization effect is exerted by the silver ions, and the silver ions are activated by the UV to enhance the sterilization effect. Moreover, by pouring the nozzle jet water to which silver ions are added onto the inner surface of the toilet bowl 12, silver ions can be adhered to the inner surface of the toilet bowl 12 to give a sterilizing effect.

  When the inner surface of the toilet bowl 12 is irradiated with ultraviolet rays, the direction of the nozzle 36 of the nozzle 3 may be inclined downward. Further, the direction may be changed continuously so as to oscillate between diagonally downward left, downward, and diagonally downward right. If it does in this way, an ultraviolet-ray can be irradiated to the wide range of the toilet bowl inner surface. In addition, the ultraviolet rays reflected from the inner surface of the toilet bowl 12 and the reservoir surface are irradiated to a wide range of the toilet seat 24 and the toilet lid 26.

  The silver ion adding means and the light emitter are provided with ON and OFF control devices, respectively. As a result, in the case of only elution of silver ions, there may be a case of only light emission.

  The nozzle 30 may be a shower nozzle or a bidet nozzle.

  The nozzle 30 may be other than the forward drive method using water pressure. For example, an air pressure driving method, a motor driving method, a linear driving method, or a combination of these may be used. In the case of a system that does not depend on water pressure, only ultraviolet rays can be irradiated without ejecting hot water from the nozzle 30.

  In FIG. 1, the low tank 20 is installed in the toilet bowl. However, the present invention can be applied to a toilet bowl having a low tank cover and a toilet bowl having no low tank.

  1 and 2, the UVLED 38 is provided on the nozzle 30, but it may be provided on the upstream side. 3 and 4 are system diagrams each showing such an embodiment.

  3 and 4, the nozzle 30 </ b> A has the same configuration except that the UVLED is removed from the nozzle 30.

  In FIG. 3, water is introduced into the water supply port of the nozzle 30 </ b> A via the electrolysis unit 40, the pipe 42, the hot water tank 44 and the pipe 46. The electrolysis unit 40 is provided with an electrode 41 for dissolving silver ions in water. The warm water tank 44 is provided with a heater 44 a and a UVLED 38. The ultraviolet light from the UV LED 38 is guided by water and introduced into the nozzle 30 </ b> A, and is irradiated to the outside from the nozzle outlet of the nozzle body 34.

  In FIG. 4, the electrolysis unit 40 is omitted, and a silver ion addition electrode 41 is provided in the hot water tank 44A instead. Also in this case, the ultraviolet light from the UV LED 38 is guided by water and introduced into the nozzle 30 </ b> A, and is irradiated to the outside from the outlet of the nozzle body 34.

  Since the photocatalyst is used in the above embodiment, visible light may be emitted instead of ultraviolet light. However, by irradiating with ultraviolet rays, the photocatalytic reaction proceeds more sufficiently and silver ions are activated.

  In the present invention, water from the nozzle may be poured onto the toilet seat or toilet lid to wash them. In this case, by combining metal ions and light irradiation, in addition to the respective effects, an effect of activating the metal ions with light is also exhibited.
