The opening 481 is provided at the lower part of the front end of the housing 400. The nozzle cleaning part 478 is located behind the opening 481. The nozzle cleaning part 478 cleans the outer peripheral surface (main body) of the nozzle 473 (self-cleaning) by spraying functional water or water from the water jetting part 478a when the nozzle 473 advances and retreats, for example.

A nozzle cover 600 is provided in front of the nozzle 473. The nozzle cover 600 is provided so as to be openable and closable with respect to the opening 481 provided at the tip of the nozzle storage portion 480. As shown in FIG. 3(b), in the state where the nozzle 473 is extended, the nozzle cover 600 is in an open state where the opening 481 is opened. As shown in FIG. 3(a), the entire nozzle 473 is housed in the nozzle In the state of the accommodating portion 480, the nozzle cover 600 is in a closed state to close the opening 481. For example, when the nozzle cover 600 is in the closed state, the front of the opening 481 is blocked by the nozzle cover 600.

The nozzle cover 600 has a back surface 600a and a surface 600b. The back surface 600a is a surface located on the side of the nozzle 473 in the closed state. The surface 600b is a surface located on the side opposite to the back surface 600a. In other words, the back surface 600a is a surface located on the rear side in the closed state, and the surface 600b is a surface located on the front side in the closed state.

As shown in (a) of FIG. 3, the nozzle 473 is accommodated in the nozzle accommodating part 480 in the unused state. In the case of partial washing by the nozzle 473, the nozzle 473 slides forward and downward with respect to the nozzle accommodating portion 480. When the nozzle 473 slides forward and downward, the nozzle 473 comes into contact with the nozzle washing part 478, and the water jetting part 478a of the nozzle washing part 478 and the nozzle cover 600 are pushed upward. For example, until the nozzle 473 reaches a predetermined position, the nozzle 473 is cleaned by the jetting water from the water jetting unit 478a.

As shown in FIG. 3(b), when the nozzle 473 reaches a predetermined position, water is discharged from the female washing spout 474a or the buttocks washing spout 474b toward the part of the user to perform washing. When the partial washing is completed, the nozzle 473 slides backward and upward toward the nozzle accommodating portion 480. For example, until the nozzle 473 is accommodated in the nozzle housing part 480, the nozzle 473 is washed by the jetting water from the water jetting part 478a. The nozzle 473 retreats to a predetermined position, and is housed in the nozzle accommodating portion 480 as in the state shown in (a) of FIG. 3.

As shown in FIG. 3(a), FIG. 3(b), FIG. 4, and FIG. 6, the toilet seat washing apparatus 100 is equipped with the illumination part 700 which irradiates the light which has a sterilization effect, ie, sterilization light. The illuminating part 700 is provided in the inside of the housing 400, for example. As shown in Figures 4 and 6, in this example, the illuminating section 700 has two light emitting sections 710. The two light emitting sections 710 are respectively provided on the left and right sides below the nozzle support section 482, facing the two light emitting sections. The upper nozzle support 482 and the nozzle 473 between 710 irradiate the sterilization light. In addition, the two light-emitting parts 710 are respectively provided on the front side (the opening 481 side) of the nozzle accommodating part 480 and irradiate the front side of the nozzle accommodating part 480 with sterilization light.

The light-emitting unit 700 has, for example, a light-emitting element 720 (light-emitting body). The light emitting element 720 is, for example, an LED (Light Emitting Diode). The light-emitting element 720 is not limited to an LED, and may be, for example, LD (Laser Diode), OLED (Organic Light Emitting Diode), or the like. The light emitting element 720 may be, for example, a cold cathode tube or a hot cathode tube. The wavelength of the sterilization light radiated from the light-emitting element 720 is, for example, 250 nm to 480 nm. The light-emitting element 720 is connected to the control unit 405 via a substrate, for example, and is turned on and off based on the control of the control unit 405. The control unit 405 controls the operation of the illumination unit 700 by controlling the lighting and extinction of the light-emitting element 720. In addition, the control unit 405 may also control the radiation intensity of the light-emitting element 720 by adjusting the voltage applied to the light-emitting element 720, for example. The light emitting element 720 is provided in the light emitting part 710, for example.

The illuminating part 700 irradiates the sterilizing light to the nozzle storage part 480. The illuminating unit 700 irradiates the sterilization light to the inside of the nozzle storage unit 480, for example. As a result, the nozzle storage section 480 is sterilized by the sterilizing light. In addition, in this example, the illuminating unit 700 also irradiates the sterilization light to the back surface 600a of the nozzle cover 600 and the surface 600b of the nozzle cover 600. Thereby, the back 600a of the nozzle cover 600 and the surface 600b of the nozzle cover 600 are also sterilized by the sterilizing light.

The illuminating part 700 dies or inactivates at least a part of the bacteria adhering to the nozzle housing part 480 etc. by irradiation of a sterilization light, for example. Thereby, the illuminating unit 700 reduces the viable bacteria adhering to the nozzle storage unit 480 and the like. In this way, the illuminating unit 700 sterilizes the nozzle storage unit 480 and the like by irradiating the sterilizing light.

Fig. 8 is a perspective view showing the periphery of a nozzle cover of the toilet seat washing device according to the embodiment. Fig. 9 is a front view showing the periphery of the nozzle cover of the toilet seat washing device according to the embodiment. Among them, the toilet cover 300 is omitted in FIG. 9. As shown in FIGS. 8 and 9, when the sterilization light is irradiated with the nozzle cover 600 in the closed state, the nozzle cover 600 and the illuminating unit 700 can emit visible light VL from the opening 481 or the nozzle cover 600 to the outside of the housing 400. In this example, a nozzle cover 600 capable of transmitting the sterilization light irradiated to the nozzle housing portion 480 is provided, and the sterilization light irradiated from the illuminating portion 700 to the nozzle housing portion 480 is transmitted through the nozzle cover 600 and emitted to the outside of the housing 400 . Among them, in this example, the sterilization light includes ultraviolet light components and visible light components.

The sterilization light is irradiated, for example, in a state in which the entire nozzle 473 is housed in the nozzle accommodating portion 480 and the nozzle cover 600 is closed (that is, the nozzle cover 600 is closed). Therefore, it is generally difficult for a user to recognize that the nozzle accommodating portion 480 is being sterilized with the sterilizing light.

On the other hand, in the embodiment, visible light VL can be emitted from the opening 481 or the nozzle cover 600 to the outside of the housing 400, so that even when the nozzle cover 600 is provided in the opening 481 of the nozzle storage portion 480, it can be used. The person recognized that the nozzle accommodating portion 480 was sterilized by the sterilizing light. As a result, since it can be recognized that the nozzle 473 is stored in a clean place, even a user with a high sense of cleaning can use the nozzle 473 with peace of mind.

Hereinafter, when the sterilization light is irradiated with the nozzle cover 600 in the closed state, the visible light VL can be emitted from the opening 481 or the nozzle cover 600 to the outside of the housing 400 will be described. Fig. 10 is a front view showing a modified example around the nozzle cover of the toilet seat washing device of the embodiment. Among them, the toilet cover 300 is omitted in FIG. 10. As a solution to be able to emit visible light VL from the opening 481 or the nozzle cover 600 to the outside of the housing 400 when the sterilization light is irradiated with the nozzle cover 600 in the closed state, it is conceivable to transfer the sterilization light itself including visible light components to the housing 400 from the opening 481. Release (leakage) of the outside. More specifically, for example, as shown in FIG. 10, by providing a gap (gap) between the opening 481 of the nozzle housing portion 480 and the nozzle cover 600, the sterilization light irradiated to the nozzle housing portion 480 can be transmitted from the opening 481 to the nozzle cover 600. The gap of the nozzle cover 600 is released to the outside of the housing 400.

In this way, in the embodiment, by providing a gap (gap) between the opening 481 of the nozzle housing portion 480 and the nozzle cover 600, the sterilization light irradiated to the nozzle housing portion 480 can be directed from the gap between the opening 481 and the nozzle cover 600. The outer side of the housing 400 is discharged. In addition, in this case, for example, the nozzle cover 600 may have a structure that does not transmit sterilizing light.

In addition, in the embodiment, the nozzle cover 600 that can transmit the sterilization light irradiated to the nozzle housing portion 480 may be provided as described above. By providing the nozzle cover 600 that can transmit the sterilizing light, for example, even if a large gap is not provided between the opening 481 of the nozzle housing portion 480 and the nozzle cover 600, the sterilizing light irradiated to the nozzle housing portion 480 can be transmitted through the nozzle. The cover 600 is released to the outside of the housing 400. As a result, it is possible to suppress the intrusion of urine and the like into the nozzle housing portion 480, and it is possible to make the user recognize that the nozzle housing portion 480 is being sterilized by the sterilizing light.

In addition, when the sterilization light does not include visible light components, for example, the sterilization light that does not include visible light components may be wavelength-converted to light including visible light components and emitted from the nozzle cover 600 to the outside of the housing 400. More specifically, the nozzle cover 600 may include a wavelength conversion material, for example. The wavelength conversion material is, for example, a material that emits light having a peak wavelength different from the irradiated light (for example, light having a peak wavelength on the longer wavelength side than the irradiated light) when irradiated with light. The wavelength conversion material is, for example, a fluorescent material. The wavelength conversion material is, for example, 2,5-thiophenediyl bis(5-tert-butyl-1,3-benzoxazole) and the like.

Since the nozzle cover 600 contains the wavelength conversion material, the wavelength of the sterilization light irradiated to the nozzle housing portion 480 can be converted by the nozzle cover 600. As a result, since, for example, the light emitted from the nozzle cover 600 to the outside of the housing 400 can be made longer than the wavelength of the sterilization light, it is possible to more safely make the user recognize that the nozzle accommodating portion 480 is being sterilized by the sterilization light. bacteria.

In addition, for example, even when the radiation intensity of the visible light component is low or the nozzle housing portion 480 is irradiated with sterilizing light that does not include visible light components, the sterilizing light can be converted into light including visible light components by the wavelength conversion material and applied to the housing. The outside of the 400 is released. Thereby, the sterilization effect can be further improved by the ultraviolet light component with high sterilization performance, and the light converted into the visible light component can be emitted to the outside of the housing 400, so that the visual confirmation effect of the user can also be satisfied.

In addition, in the embodiment, the nozzle cover 600 may include, for example, a light-storing material. The light storage material is, for example, a material that absorbs the energy of the irradiated light and emits it as light. The light-storing material is, for example, strontium aluminate or the like.

Since the sterilizing light is light having a sterilizing effect, it is preferable not to irradiate the user substantially. Since the nozzle cover 600 contains the light-storing material, even when the sterilization light is not actually irradiated to the inside of the nozzle storage portion 480, it can be observed that the inside of the nozzle storage portion 480 is sterilized by the sterilization light. As a result, it is possible to more safely make the user recognize that the inside of the nozzle accommodating portion 480 is being sterilized with the sterilizing light.

Next, the sterilization light irradiated from the illumination unit 700 will be described. In the embodiment, the illuminating unit 700 irradiates sterilizing light including ultraviolet light components and visible light components, for example. In this way, by irradiating the nozzle accommodating portion 480 with both ultraviolet light components with high sterilization performance and visible light components whose sterilization performance is lower than the ultraviolet light components but can be visually confirmed, for example, the sterilization light itself is emitted from the opening 481. When emitting (leaking) to the outside of the housing 400, the sterilizing effect of the sterilizing light can be compatible with the visual confirmation effect of the user.

The visible light component only needs to have a radiation intensity that can be visually confirmed by the user. In order to improve the sterilization effect, it is preferable to increase the radiation intensity of the ultraviolet light component. In view of this, in the embodiment, the illuminating unit 700 irradiates, for example, sterilizing light whose radiation intensity of an ultraviolet light component is greater than that of a visible light component. As a result, it is possible to satisfy the user's visual confirmation effect and further improve the sterilization effect.

The peak wavelength of the sterilization light is 250 nm or more and 480 nm or less, for example. The peak wavelength of the sterilization light is preferably 350 nm or more and 480 nm or less. In this way, by setting the peak wavelength of the sterilizing light to the boundary between the visible light region and the ultraviolet light region, that is, near 400 nm (for example, 350 nm or more and 480 nm or less), it is possible to irradiate the ultraviolet light component and the visible light component from a single light source (light emitting element 720). Sterilizing light. Thereby, the number of light sources provided in the illumination part 700 can be reduced, and the toilet seat washing apparatus 100 can be reduced in size.

Fig. 11 is a graph showing an example of the wavelength distribution of sterilization light in the toilet seat washing device of the embodiment. As shown in FIG. 11, in this example, the sterilization light includes light having a wavelength of about 360 nm to about 420 nm, and the peak wavelength is about 385 nm. In this way, by setting the peak wavelength of the sterilization light to be near the boundary between the visible light region and the ultraviolet light region, it is possible to irradiate, for example, ultraviolet light components, namely UV-A components (315nm or more and 400nm or less) and violet to blue visible light components ( 400nm above 480nm) sterilizing light. With such a sterilizing light, it is possible to have both the sterilizing effect and the visual confirmation effect of the user.

In addition, the light source of the sterilization light is not limited to one. For example, as the sterilization light, it is also possible to irradiate light including an ultraviolet light component and not including a visible light component from one light source, and irradiate light including a visible light component and not including an ultraviolet light component from another light source. In other words, the ultraviolet light component and the visible light component included in the sterilization light can be irradiated from different light sources at the same time.

In addition, the sterilization light is not limited to light including ultraviolet light components and visible light components. For example, in the case where the nozzle cover 600 includes a wavelength conversion material, the sterilizing light may be light including ultraviolet light components and not including visible light components.

Fig. 12 is a plan view showing a modified example of the illumination unit of the toilet seat washing device of the embodiment. As shown in FIG. 12, the light-emitting element 720 may be provided at a position away from the nozzle accommodating portion 480. In this example, two light-emitting elements 720 are provided at positions away from the nozzle accommodating part 480 to the left and right. The two light-emitting elements 720 are respectively provided with two light-emitting parts provided on the left and right sides of the nozzle accommodating part 480 via an optical fiber 730. 710 connection.

In the embodiment, the sterilizing light can be guided from the light emitting element 720 to the light emitting unit 710 using the optical fiber 730 or the like, and the sterilizing light can be irradiated to the nozzle storage unit 480 from the light emitting unit 710 provided in the vicinity of the nozzle storage unit 480.

Next, a specific example of the operation of the toilet seat washing device of the embodiment will be described with reference to the drawings. Fig. 13 is a time chart illustrating a specific example of the operation of the toilet seat washing device of the embodiment. As shown in FIG. 13, in a state where the human body sensor 403 does not detect the user, the illuminating unit 700 does not operate (time t0). More specifically, the light-emitting element 720 (for example, LED) of the light-emitting unit 700 is extinguished (turned off).

When the human body sensor 403 detects a user approaching the toilet seat washing device 100, the control unit 405 activates the illuminating unit 700 (time t1). More specifically, the control unit 405 turns on (turns on) the light-emitting element 720 of the illumination unit 700. However, when the illumination unit 700 is operating in a state where the user is not detected, the control unit 405 continues the operation of the illumination unit 700 even after detecting the user.

In this way, by operating the illuminating unit 700 at the time when it is detected that the user approaches the toilet seat washing device 100, it is possible to make the user recognize that the nozzle accommodating portion 480 is sterilized by the sterilizing light before the user sits on the toilet seat 200 . As a result, since it can be recognized that the nozzle 473 is stored in a clean place, even a user with a high sense of cleaning can use the nozzle 473 with peace of mind.

The lighting unit 700 continues to operate, for example, until the seating sensor 404 detects the seating of the user. In other words, the control unit 405 continues to operate the lighting unit 700 in a state where the human body sensor 403 detects the user and the seating sensor 404 does not detect seating.

If the seating sensor 404 detects the seating of the user, the control unit 405 stops the operation of the illumination unit 700 (time t2). More specifically, the control unit 405 turns off (turns off) the light emitting element 720 of the illumination unit 700.

After the user sits on the toilet seat 200, the user cannot visually confirm the nozzle storage portion 480. In addition, when the sterilization light leaks from the opening 481 to the outside of the housing 400, it becomes a state where it is easy to irradiate a part of the sterilization light to the user. In contrast, by stopping the operation of the illuminating section 700 when the user is seated on the toilet seat 200, it is possible to make the user recognize that the nozzle storage section 480 is being sterilized with the sterilizing light without causing damage to the nozzle housing portion 480. The user irradiates the sterilizing light, which can further improve the safety of the user.

The lighting unit 700 continues to stop working, for example, until the seating sensor 404 detects the user's departure from the seat. In other words, in a state where the seating sensor 404 detects the seating, the control unit 405 continuously stops the operation of the illuminating unit 700.

If the seating sensor 404 detects the departure of the user (if the seating sensor 404 changes from a state that detects seating to a state that does not detect seating), the control unit 405 activates the illumination unit 700 ( Time t3). More specifically, the control unit 405 turns on (turns on) the light-emitting element 720 of the illumination unit 700. Thereby, the user who has left the seat can recognize that the sterilization of the nozzle accommodating portion 480 has restarted.

The illuminating unit 700 continues to operate until the predetermined time TM1 elapses. In other words, even if the human sensor 403 changes from the state in which the user is detected to the state in which the user is not detected, the control unit 405 continues to operate the illumination unit 700 until the predetermined time TM1 has elapsed (time t4).

When the predetermined time TM1 has elapsed, the control unit 405 stops the operation of the illumination unit 700 (time t5). More specifically, the control unit 405 turns off (turns off) the light emitting element 720 of the illumination unit 700.

When the predetermined time TM2 has elapsed in the unused state, the illuminating unit 700 operates. In other words, if the predetermined time TM2 has elapsed in a state where the human sensor 403 cannot detect the user and the seating sensor 404 does not detect seating, the control unit 405 activates the illumination unit 700 (time t6). More specifically, the control unit 405 turns on (turns on) the light-emitting element 720 of the illumination unit 700. In this way, the control unit 405 can operate the lighting unit 700 in a state where the human body sensor 403 does not detect the user.

By irradiating the sterilization light even when the human body sensor 403 does not detect the user, the irradiation time of the sterilization light can be increased. Thereby, the sterilization effect of the sterilization light can be improved. In addition, by increasing the irradiation time of the sterilization light, even when the sterilization light having a relatively long peak wavelength is irradiated, it is possible to suppress the decrease in the sterilization effect. Therefore, it is possible to improve the safety of the user while suppressing the decrease in the sterilization effect. In addition, by irradiating the sterilizing light with a relatively long peak wavelength, it is also possible to suppress the deterioration of the resin member inside the nozzle housing portion 480.

When the predetermined time TM3 has elapsed, the control unit 405 stops the operation of the illumination unit 700 (time t7). More specifically, the control unit 405 turns off (turns off) the light emitting element 720 of the illumination unit 700.

The prescribed time TM1~TM3 can be any time. The predetermined time TM1 to TM3 are set, for example, so that the operating time of the illumination unit 700 in the state where the human sensor 403 does not detect the user is longer than the operating time of the illumination unit 700 in the state where the human sensor 403 detects the user. . In other words, the control unit 405 controls the illumination unit 700 so that the operating time of the illumination unit 700 in a state where the human sensor 403 does not detect the user is longer than that of the illumination unit 700 in a state where the human sensor 403 detects the user. Long work time. In this way, by making the operating time (irradiation time of the sterilization light) of the illumination unit 700 in a state where the human sensor 403 does not detect the user longer, the sterilization effect inside the nozzle storage unit 480 can be further improved.

Fig. 14 is a front view showing the periphery of the nozzle cover of the toilet seat washing device according to the embodiment. As shown in FIG. 14, when at least one of the nozzle cover 600 and the vicinity 650 of the nozzle cover 600 is irradiated with sterilizing light from the illumination unit 700 to the inside of the nozzle storage unit 480 when the nozzle cover 600 is closed, the user The status that can be confirmed visually lights up.

In FIG. 14, the nozzle cover 600 and the vicinity 650 of the nozzle cover 600 are indicated by hatching. That is, in the embodiment, when the sterilization light is irradiated from the illuminating portion 700 to the inside of the nozzle storage portion 480 with the nozzle cover 600 in the closed state, at least a part of the area indicated by the hatching in FIG. The visually confirmed state lights up. However, when the nozzle cover 600 is shiny, at least the surface 600b (outer surface) is shiny. When the vicinity 650 of the nozzle cover 600 shines, at least the surface (outer surface) on the surface 600b side of the nozzle cover 600 shines.

The vicinity 650 of the nozzle cover 600 includes, for example, a gap (a gap) between the opening 481 of the nozzle housing portion 480 and the nozzle cover 600 and a part of the front surface 400 a of the housing 400. More specifically, the vicinity 650 of the nozzle cover 600 is an area within 5 cm from the nozzle cover 600, for example.

In the specification of the present application, "lighting in a state that can be visually confirmed by the user" means, for example, that at least one of the nozzle cover 600 and the vicinity 650 of the nozzle cover 600 is larger than the other part (for example, the front surface of the housing 400). In 400a, the part 5 cm or more from the nozzle cover 600) is in a bright state. In addition, the state of “lighting up in a state that can be visually confirmed by the user” is not limited to a state in which at least one of the nozzle cover 600 and the vicinity 650 of the nozzle cover 600 emits visible light. The state of "lighting in a state that can be visually confirmed by the user" may be, for example, a state in which visible light irradiated from a light source passes through at least one of the nozzle cover 600 and the vicinity 650 of the nozzle cover 600 to illuminate the transmitted position brightly. The visible light irradiated from the light source may be reflected to at least one of the nozzle cover 600 and the vicinity 650 of the nozzle cover 600 to brighten the reflection position.

In this way, according to the embodiment, since the opening 481 of the nozzle accommodating section 480 is closed by the nozzle cover 600 in a state where the entire nozzle 473 is housed in the nozzle accommodating section 480, it is possible to suppress the intrusion of urine and the like into the nozzle accommodating section 480. In addition, when the sterilization light is irradiated from the illuminating portion 700 to the inside of the nozzle housing portion 480 while the nozzle cover 600 is in the closed state, it can be visually confirmed by the user through at least one of the nozzle cover 600 and the vicinity 650 of the nozzle cover 600 The state is illuminated, so that even when the nozzle cover 600 is closed, the user can actually feel that the inside of the nozzle housing portion 480 is being sterilized by the sterilization light. Thereby, since the user can recognize that the nozzle 473 is stored in a clean place, even a user with a high sense of cleaning can use the nozzle 473 with peace of mind.

At least one of the nozzle cover 600 and the vicinity 650 of the nozzle cover 600 is illuminated by, for example, the sterilization light irradiated from the illumination unit 700 to the inside of the nozzle storage unit 480. In other words, the illuminating part 700 uses the sterilization light irradiated to the inside of the nozzle housing part 480 to illuminate at least one of the nozzle cover 600 and the vicinity 650 of the nozzle cover 600, for example.

In this way, at least one of the nozzle cover 600 and the vicinity 650 of the nozzle cover 600 is illuminated by the sterilization light irradiated from the illuminating part 700 to the inside of the nozzle housing part 480, which enables the user to visually feel the actual use. The sterilization light sterilizes the inside of the nozzle storage section 480.

Fig. 15(a) and Fig. 15(b) are explanatory diagrams schematically showing the periphery of the illuminating part of the toilet seat washing device of the embodiment. As shown in FIG. 15(a) and FIG. 15(b), the illuminating part 700 irradiates the sterilization light containing an ultraviolet light component, for example. In addition, the illuminating part 700 is provided in the inside of the housing 400 (inside the nozzle cover 600), for example. In this way, by irradiating the sterilization light including the ultraviolet light component from the illumination unit 700 provided inside the housing 400, it is possible to more reliably irradiate the sterilization light including the ultraviolet light component to the inside of the nozzle storage unit 480.

In addition, in the case where the nozzle cover 600 contains a wavelength conversion material (such as a fluorescent material) capable of converting ultraviolet light components into visible light components as described above, as shown in FIG. 15(a), the illuminating portion 700 passes through the nozzle The cover 600 converts the ultraviolet light components included in the sterilization light into visible light components, so that the nozzle cover 600 can be brightened.

In this way, since the nozzle cover 600 contains the wavelength conversion material, even if a large gap for leaking light is not provided between the opening 481 of the nozzle housing portion 480 and the nozzle cover 600, the nozzle cover located outside the nozzle housing portion 480 can be used. 600 shines. As a result, it is possible to more reliably prevent urine from entering between the opening 481 of the nozzle accommodating portion 480 and the nozzle cover 600, and it is also possible for the user to visually feel that the inside of the nozzle accommodating portion 480 is being treated with the sterilizing light. Sterilization.

As shown in (b) of FIG. 15, the illuminating part 700 may irradiate sterilizing light including ultraviolet light components and visible light components. By irradiating the sterilizing light including ultraviolet light components and visible light components from the illuminating unit 700 provided inside the housing 400 in this way, even if no other illuminating unit 750 or the like that irradiates light including visible light components is provided, the user can be recognized The nozzle accommodating part 480 is sterilized by the sterilizing light.

In this case, it is preferable that the nozzle cover 600 has a transmission portion 610 capable of transmitting visible light components. The transmittance of the visible light component of the transmission portion 610 is higher than the transmittance of the visible light component of the front surface 400 a of the housing 400, for example. The illuminating section 700 transmits visible light components through the transmission section 610, so that the nozzle cover 600 can be illuminated.

In this way, the nozzle cover 600 has the transparent portion 610, which can improve the performance of sterilizing the inside of the nozzle storage portion 480 by the ultraviolet light component included in the sterilizing light irradiated from the illuminating portion 700, and can also pass through the illuminating portion 700.
