As shown in FIGS. 3A, 3B, and 7, an opening 481 is provided at the front end of the nozzle storage section 480. The opening 481 is provided at the lower part of the front end of the casing 400. Nozzle cleaning section 478 is located behind opening 481 . The nozzle cleaning unit 478 cleans the outer circumferential surface (body) of the nozzle 473, for example, by jetting functional water or water from the water spouting unit 478a when the nozzle 473 moves back and forth (self-cleaning).

A nozzle lid 600 is provided in front of the nozzle 473. The nozzle lid 600 is provided so as to be openable and closable with respect to an opening 481 provided at the front end of the nozzle storage section 480. As shown in FIG. 3B, the nozzle lid 600 is in an open state in which the opening 481 is opened when the nozzle 473 is advanced, and as shown in FIG. When it is housed in the opening 481, it is in a closed state. For example, when the nozzle lid 600 is in a closed state, the front side of the opening 481 is blocked by the nozzle lid 600.

Nozzle lid 600 has a back surface 600a and a front surface 600b. The back surface 600a is a surface located on the nozzle 473 side in the closed state. The front surface 600b is a surface located on the opposite side 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 front surface 600b is a surface located on the front side in the closed state.

When the nozzle 473 is not in use, it is stored in the nozzle storage section 480, as shown in FIG. 3(a). When the nozzle 473 performs private cleaning, the nozzle 473 slides forward and downward with respect to the nozzle storage section 480. When the nozzle 473 slides forward and downward, the nozzle 473 contacts the nozzle cleaning section 478, and the water spouting section 478a of the nozzle cleaning section 478 and the nozzle lid 600 are pushed upward. For example, before the nozzle 473 reaches a predetermined position, the nozzle 473 is cleaned by water spouted from the water spouting section 478a.

As shown in FIG. 3(b), when the nozzle 473 reaches a predetermined position, water is discharged from the bidet cleaning spout 474a or the butt cleaning spout 474b toward the user's private parts to perform cleaning. When the private part cleaning is completed, the nozzle 473 slides rearward and upward toward the nozzle storage section 480. For example, before the nozzle 473 is stored in the nozzle storage section 480, the nozzle 473 is cleaned by water spouted from the water spouting section 478a. The nozzle 473 is retreated to a predetermined position and is housed in the nozzle housing section 480 as in the state shown in FIG. 3(a).

As shown in FIGS. 3A, 3B, 4, and 6, the sanitary cleaning device 100 includes a lighting section 700 that emits sterilization light that has a sterilization effect. The illumination unit 700 is provided inside the casing 400, for example. As shown in FIGS. 4 and 6, in this example, the illumination section 700 has two light emitting sections 710. The two light emitting parts 710 are provided on the left and right sides below the nozzle support part 482, respectively, and sterilization is performed toward the nozzle support part 482 and the nozzle 473 located above between the two light emitting parts 710. Irradiate light. Further, the two light emitting sections 710 are each provided on the front side of the nozzle storage section 480 (opening 481 side), and irradiate the front side of the nozzle storage section 480 with sterilization light.

The illumination unit 700 includes, for example, a light emitting element 720 (light emitter). 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, an LD (Laser Diode) or an OLED (Organic Light Emitting Diode). The light emitting element 720 may be, for example, a cold cathode tube or a hot cathode tube. The wavelength of the sterilization light emitted by 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, for example, a substrate, 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 extinguishing of the light emitting element 720. Further, the control unit 405 may control the radiation intensity of the light emitting element 720, for example, by adjusting the voltage applied to the light emitting element 720. The light emitting element 720 is provided in the light emitting section 710, for example.

The illumination section 700 irradiates the nozzle storage section 480 with sterilization light. For example, the illumination unit 700 irradiates the inside of the nozzle storage unit 480 with sterilization light. Thereby, the nozzle housing section 480 is sterilized by the sterilizing light. In this example, the illumination unit 700 also irradiates the back surface 600a of the nozzle lid 600 and the front surface 600b of the nozzle lid 600 with the sterilization light. Thereby, the back surface 600a of the nozzle lid 600 and the front surface 600b of the nozzle lid 600 are also sterilized by the sterilization light.

The illumination unit 700 kills or inactivates at least a portion of bacteria attached to the nozzle storage unit 480 and the like by, for example, irradiating with sterilization light. Thereby, the illumination unit 700 reduces live bacteria attached to the nozzle storage unit 480 and the like. In this way, the illumination unit 700 sterilizes the nozzle storage unit 480 and the like by irradiating the sterilization light.

FIG. 8 is a perspective view showing the vicinity of the nozzle lid of the sanitary cleaning device according to the embodiment.
FIG. 9 is a front view showing the vicinity of the nozzle lid of the sanitary cleaning device according to the embodiment.
In addition, in FIG. 9, the toilet lid 300 is omitted.
As shown in FIGS. 8 and 9, when the nozzle lid 600 and the illumination unit 700 are in the closed state, visible light VL is transmitted from the opening 481 or the nozzle lid 600 to the outside of the casing 400 when irradiating sterilization light. can be released. In this example, a nozzle lid 600 is provided that can transmit the sterilization light irradiated onto the nozzle storage section 480, and the sterilization light irradiated onto the nozzle storage section 480 from the illumination section 700 is transmitted through the nozzle lid 600. Then, it is released to the outside of the casing 400. Note that in this example, the sterilization light includes an ultraviolet light component and a visible light component.

Irradiation with sterilizing light is performed, for example, with the entire nozzle 473 housed in the nozzle storage section 480 and with the nozzle lid 600 closed (that is, the nozzle lid 600 is in a closed state). Therefore, it is usually difficult for the user to recognize that the nozzle housing section 480 is being sterilized with the sterilizing light.

In contrast, in the embodiment, visible light VL can be emitted from the opening 481 or the nozzle lid 600 to the outside of the casing 400, so that when the nozzle lid 600 is provided in the opening 481 of the nozzle storage section 480, Also, the user can be made aware that the nozzle housing section 480 is being sterilized with the sterilizing light. Thereby, it can be recognized that the nozzle 473 is stored in a clean place, so even a user who is highly conscious of cleanliness can use the nozzle 473 with peace of mind.

Hereinafter, a means for making it possible to emit visible light VL from the opening 481 or the nozzle lid 600 to the outside of the casing 400 when irradiating the sterilization light with the nozzle lid 600 in the closed state will be described.
FIG. 10 is a front view showing a modified example of the nozzle lid periphery of the sanitary cleaning device according to the embodiment.
Note that in FIG. 10, the toilet lid 300 is omitted.
When the nozzle lid 600 is in the closed state, the means for emitting visible light VL from the opening 481 or the nozzle lid 600 to the outside of the casing 400 when irradiating the sterilizing light is to emit the sterilizing light itself containing a visible light component to the opening 481. It is conceivable that the water be released (leaked) from the casing 400 to the outside of the casing 400. More specifically, for example, as shown in FIG. 10, by providing a gap (clearance) between the opening 481 of the nozzle housing part 480 and the nozzle lid 600, the sterilization light irradiated onto the nozzle housing part 480 can be removed. can be released to the outside of the casing 400 through the gap between the opening 481 and the nozzle lid 600.

In this way, in the embodiment, by providing a gap (clearance) between the opening 481 of the nozzle housing section 480 and the nozzle lid 600, the sterilization light irradiated onto the nozzle housing section 480 is transmitted between the opening 481 and the nozzle lid 600. It may be discharged to the outside of the casing 400 through the gap between the two. Note that in this case, for example, the nozzle lid 600 may not transmit sterilization light.

Further, in the embodiment, as described above, the nozzle lid 600 that can transmit the sterilization light irradiated onto the nozzle storage section 480 may be provided. By providing the nozzle lid 600 that can transmit the sterilizing light, the sterilizing light irradiated to the nozzle accommodating part 480 can be removed without having to provide a large clearance between the opening 481 of the nozzle accommodating part 480 and the nozzle lid 600, for example. Light can be transmitted through the nozzle lid 600 and emitted to the outside of the casing 400. This allows the user to recognize that the nozzle storage section 480 is being sterilized with the sterilization light while suppressing the intrusion of urine and the like into the nozzle storage section 480.

In addition, when the sterilization light does not include a visible light component, for example, the wavelength of the sterilization light that does not include a visible light component is converted into light that includes a visible light component, and the converted light is emitted from the nozzle lid 600 to the outside of the casing 400. You may. More specifically, nozzle lid 600 may include, for example, a wavelength converting material. A wavelength conversion material is, for example, a material that, when irradiated with light, emits light that has a peak wavelength different from that of the irradiated light (for example, light that has a peak wavelength on the longer wavelength side than the irradiated light). It is. The wavelength conversion material is, for example, a fluorescent material. The wavelength conversion material is, for example, 2,5-thiophenediylbis(5-tert-butyl-1,3-benzoxazole).

By including the wavelength conversion material in the nozzle lid 600, the wavelength of the sterilization light irradiated onto the nozzle housing section 480 can be converted by the nozzle lid 600. As a result, for example, the light emitted from the nozzle lid 600 to the outside of the casing 400 can have a longer wavelength than the sterilizing light, so that the nozzle housing section 480 can be sterilized more safely with the sterilizing light. The user can be made aware of this.

For example, even when the radiation intensity of the visible light component is low or when the nozzle housing section 480 is irradiated with sterilization light that does not contain the visible light component, the sterilization light can be converted into light containing the visible light component by the wavelength conversion material. It can be converted into and discharged to the outside of the casing 400. As a result, the sterilization effect can be further enhanced by the ultraviolet light component with high sterilization performance, and by emitting light that has been converted to include a visible light component to the outside of the casing 400, it is visible to the user. The effect can also be satisfied.

Further, in the embodiment, the nozzle lid 600 may include, for example, a luminescent material. A luminescent material is, for example, a material that absorbs the energy of irradiated light and emits it as light. The luminous material is, for example, strontium aluminate.

Since the sterilizing light has a sterilizing effect, it is basically preferable not to irradiate the user with the sterilizing light. Since the nozzle lid 600 includes a luminescent material, it appears that the inside of the nozzle housing part 480 is sterilized with the sterilizing light even when the inside of the nozzle housing part 480 is not actually irradiated with the sterilizing light. It becomes possible to show the This allows the user to more safely recognize that the inside of the nozzle housing section 480 is being sterilized with the sterilizing light.

Next, the sterilization light irradiated from the illumination unit 700 will be explained.
In the embodiment, the illumination unit 700 irradiates, for example, sterilization light containing an ultraviolet light component and a visible light component. In this way, by irradiating the nozzle housing section 480 with irradiation light that includes both the ultraviolet light component that has high sterilization performance and the visible light component that has lower sterilization performance than the ultraviolet light component but is visible, For example, when the sterilizing light itself is emitted (leaked) from the opening 481 to the outside of the casing 400, both the sterilizing effect of the sterilizing light and the visual effect for the user can be achieved.

It is sufficient that the visible light component has a radiation intensity that is visible to the user, and in order to enhance the sterilization effect, it is desirable to increase the radiation intensity of the ultraviolet light component. Therefore, in the embodiment, the illumination unit 700 irradiates, for example, sterilization light in which the radiation intensity of the ultraviolet light component is higher than the radiation intensity of the visible light component. Thereby, the sterilization effect can be further enhanced while satisfying the visual recognition effect for the user.

The peak wavelength of the sterilization light is, for example, 250 nm or more and 480 nm or less. The peak wavelength of the sterilizing light is preferably 350 nm or more and 480 nm or less. In this way, by setting the peak wavelength of the sterilization light to around 400 nm, which is the boundary between the visible light range and the ultraviolet light range (for example, 350 nm or more and 480 nm or less), the ultraviolet light component can be extracted from one light source (light emitting element 720). It is possible to irradiate sterilizing light containing a visible light component and a visible light component. Thereby, the number of light sources provided in the illumination section 700 can be further reduced, and the sanitary cleaning device 100 can be downsized.

FIG. 11 is a graph showing an example of the wavelength distribution of sterilization light of the sanitary cleaning device according to the embodiment.
As shown in FIG. 11, in this example, the sterilization light includes light with 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 near the boundary between the visible light region and the ultraviolet light region, for example, the UV-A component (315 nm or more and 400 nm or less), which is the ultraviolet light component, and the violet to blue light component can be Sterilization light containing a visible light component (400 nm or more and 480 nm or less) can be irradiated. Such sterilizing light can achieve both a sterilizing effect and a visual effect for the user.

Note that the light source of the sterilization light is not limited to one. For example, as sterilization light, one light source may emit light that contains an ultraviolet light component and no visible light component, and another light source may emit light that contains a visible light component and does not contain an ultraviolet light component. . In other words, the ultraviolet light component and the visible light component included in the sterilization light may be irradiated simultaneously from different light sources.

Furthermore, the sterilization light is not limited to light containing an ultraviolet light component and a visible light component. For example, when the nozzle lid 600 includes a wavelength conversion material, the sterilization light may be light that contains an ultraviolet light component and does not contain a visible light component.

FIG. 12 is a plan view showing a modification of the illumination part of the sanitary cleaning device according to the embodiment.
As shown in FIG. 12, the light emitting element 720 may be provided at a position away from the nozzle housing section 480. In this example, two light emitting elements 720 are provided at positions left and right away from the nozzle housing part 480, and the two light emitting elements 720 are connected to the left and right sides of the nozzle housing part 480 via optical fibers 730, respectively. It is connected to two light emitting sections 710 provided in the.

In the embodiment, as described above, sterilization light is guided from the light emitting element 720 to the light emitting unit 710 using the optical fiber 730 or the like, and sterilization is carried out from the light emitting unit 710 provided near the nozzle housing 480 to the nozzle housing 480. Light may be irradiated.

Next, a specific example of the operation of the sanitary cleaning device according to the embodiment will be described with reference to the drawings.
FIG. 13 is a timing chart illustrating a specific example of the operation of the sanitary cleaning device according to the embodiment.
As shown in FIG. 13, when the human body detection sensor 403 does not detect the user, the illumination unit 700 is not activated (timing t0). More specifically, the light emitting element 720 (for example, an LED) of the illumination unit 700 is turned off (OFF).

When the human body detection sensor 403 detects a user approaching the sanitary cleaning device 100, the control unit 405 activates the illumination unit 700 (timing t1). More specifically, the control unit 405 turns on the light emitting element 720 of the illumination unit 700 (ON). Note that, if the illumination unit 700 is operating without detecting the user, the control unit 405 causes the illumination unit 700 to continue operating even after the user is detected.

In this way, by activating the illumination unit 700 at the timing when it is detected that the user approaches the sanitary cleaning device 100, the nozzle storage unit 480 can be cleaned with sterilizing light before the user sits on the toilet seat 200. The user can be made aware of the presence of bacteria. Thereby, it can be recognized that the nozzle 473 is stored in a clean place, so even a user who is highly conscious of cleanliness can use the nozzle 473 with peace of mind.

For example, the illumination unit 700 continues to operate until the seating detection sensor 404 detects that the user is seated. In other words, the control unit 405 continues to operate the illumination unit 700 in a state where the human body detection sensor 403 detects the user and the seating detection sensor 404 does not detect seating.

When the seating detection sensor 404 detects that the user is seated, the control unit 405 stops the operation of the illumination unit 700 (timing t2). More specifically, the control unit 405 turns off the light emitting element 720 of the illumination unit 700 (OFF).

After the user sits on the toilet seat 200, the nozzle housing section 480 is no longer visible to the user. Furthermore, if the sterilizing light is leaking to the outside of the casing 400 from the opening 481, the user is likely to be partially irradiated with the sterilizing light. On the other hand, by stopping the operation of the illumination section 700 at the timing when the user sits on the toilet seat 200, the effect of making the user aware that the nozzle storage section 480 is being sterilized with the sterilization light is lost. The user can be prevented from being irradiated with sterilizing light, thereby further increasing the safety of the user.

For example, the illumination unit 700 continues to stop operating until the seating detection sensor 404 detects that the user leaves the seat. In other words, the control unit 405 continues to stop the operation of the illumination unit 700 while the seating detection sensor 404 detects seating.

When the seating detection sensor 404 detects that the user leaves the seat (when the seating detection sensor 404 changes from a state in which it detects seating to a state in which it does not detect seating), the control unit 405 activates the illumination unit 700 ( timing t3). More specifically, the control unit 405 turns on the light emitting element 720 of the illumination unit 700 (ON). Thereby, the user who has left the seat can be made aware that sterilization of the nozzle housing section 480 has been resumed.

The illumination unit 700 continues to operate until the predetermined time TM1 has elapsed. In other words, the control unit 405 continues to operate the illumination unit 700 until the predetermined time TM1 has elapsed (timing t4).

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

The illumination unit 700 is activated when a predetermined time TM2 has elapsed in an unused state. In other words, the control unit 405 activates the illumination unit 700 when the predetermined time TM2 has elapsed while the human body detection sensor 403 does not detect the user and the seating detection sensor 404 does not detect the seating. timing t6). More specifically, the control unit 405 turns on the light emitting element 720 of the illumination unit 700 (ON). In this manner, the control unit 405 may operate the illumination unit 700 in a state where the human body detection sensor 403 does not detect the user.

By irradiating the sterilizing light even when the human body detection sensor 403 does not detect a user, the irradiation time of the sterilizing light can be extended. Thereby, the sterilizing effect of the sterilizing light can be enhanced. Moreover, by increasing the irradiation time of the sterilizing light, even when irradiating the sterilizing light having a relatively long peak wavelength, it is possible to suppress the deterioration of the sterilizing effect. Therefore, it is possible to increase safety for the user while suppressing a decrease in the sterilization effect. Further, by irradiating sterilizing light with a relatively long peak wavelength, deterioration of the resin member inside the nozzle storage section 480 can be suppressed.

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

The predetermined times TM1 to TM3 may be arbitrary times. The predetermined times TM1 to TM3 are, for example, the operating time of the illumination unit 700 when the human body detection sensor 403 is not detecting the user, and the operation time of the illumination unit 700 when the human body detection sensor 403 is detecting the user. It is set so that it is longer than the time. In other words, the control unit 405 determines, for example, that the operating time of the illumination unit 700 in a state where the human body detection sensor 403 is not detecting a user is the same as the operating time of the illumination unit 700 in a state where the human body detection sensor 403 is detecting a user. The illumination unit 700 is controlled so that the operating time is longer than the operating time. In this way, by lengthening the operating time of the illumination unit 700 (the irradiation time of the sterilization light) when the human body detection sensor 403 is not detecting the user, the sterilization effect inside the nozzle storage unit 480 can be improved. It can be further increased.

FIG. 14 is a front view showing the vicinity of the nozzle lid of the sanitary cleaning device according to the embodiment.
As shown in FIG. 14, at least one of the nozzle lid 600 and the vicinity 650 of the nozzle lid 600 is illuminated with sterilization light from the illumination unit 700 into the nozzle storage unit 480 when the nozzle lid 600 is closed. At the same time, it lights up so that it can be seen by the user.

In FIG. 14, the nozzle lid 600 and the vicinity 650 of the nozzle lid 600 are shown by hatching. That is, in the embodiment, when the nozzle lid 600 is in the closed state and the inside of the nozzle housing section 480 is irradiated with sterilization light from the illumination section 700, at least a part of the area shown by hatching in FIG. 14 is used. Shines in a state that is visible to people. Note that when the nozzle lid 600 lights up, at least the surface 600b (outer surface) lights up. When the vicinity 650 of the nozzle lid 600 lights up, at least the surface (outer surface) on the surface 600b side of the nozzle lid 600 lights up.

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

In the specification of this application, "shining in a state that is visible to the user" means, for example, that at least one of the nozzle lid 600 and the vicinity 650 of the nozzle lid 600 The area that is 5 cm or more away from the nozzle lid 600) is brighter than the other area. Note that the state of "shining in a state that is visible to the user" is not limited to a state in which at least one of the nozzle lid 600 and the vicinity 650 of the nozzle lid 600 emits visible light. The state of "shining in a state that is visible to the user" means, for example, that the visible light emitted from the light source passes through at least one of the nozzle lid 600 and the vicinity 650 of the nozzle lid 600, so that the transmitted point is brightly illuminated. The visible light irradiated from the light source may be reflected on at least one of the nozzle lid 600 and the vicinity 650 of the nozzle lid 600, so that the reflected location is brightly illuminated.

Thus, according to the embodiment, when the entire nozzle 473 is housed inside the nozzle housing part 480, the opening 481 of the nozzle housing part 480 is closed by the nozzle lid 600, so that the nozzle housing part 480 It is possible to suppress the intrusion of urine, etc. into the inside of the body. Further, when the nozzle lid 600 is in a closed state and the sterilization light is irradiated into the nozzle housing section 480 from the illumination section 700, at least one of the nozzle lid 600 and the vicinity 650 of the nozzle lid 600 is visible to the user. By illuminating in the possible state, the user can visually feel that the inside of the nozzle housing section 480 is being sterilized with the sterilizing light even when the nozzle lid 600 is closed. This allows the user to recognize that the nozzle 473 is stored in a clean place, so even users who are highly conscious of cleanliness can use the nozzle 473 with peace of mind.

At least one of the nozzle lid 600 and the vicinity 650 of the nozzle lid 600 is illuminated using, for example, the sterilization light irradiated from the illumination section 700 into the nozzle storage section 480. In other words, the illumination unit 700 illuminates at least one of the nozzle lid 600 and the vicinity 650 of the nozzle lid 600, for example, using the sterilization light irradiated into the nozzle storage unit 480.

In this way, at least one of the nozzle lid 600 and the vicinity 650 of the nozzle lid 600 lights up using the sterilizing light irradiated into the nozzle storage section 480 from the illumination section 700, so that the nozzle storage section 480 is illuminated. The user can visually feel that the inside is being sterilized with the sterilizing light.

FIGS. 15(a) and 15(b) are explanatory diagrams schematically showing the vicinity of the illumination part of the sanitary cleaning device according to the embodiment.
As shown in FIGS. 15(a) and 15(b), the illumination unit 700 irradiates, for example, sterilization light containing an ultraviolet light component. Further, the illumination unit 700 is provided inside the casing 400 (inside the nozzle lid 600), for example. In this way, by irradiating the sterilization light containing the ultraviolet light component from the illumination unit 700 provided inside the casing 400, the inside of the nozzle storage section 480 is more reliably irradiated with the sterilization light containing the ultraviolet light component. be able to.

Further, as described above, when the nozzle lid 600 includes a wavelength conversion material (for example, a fluorescent material) capable of converting an ultraviolet light component into a visible light component, the illumination part 700 By converting the ultraviolet light component contained in the sterilization light into a visible light component in the nozzle lid 600, the nozzle lid 600 can be illuminated.

In this way, since the nozzle lid 600 includes the wavelength conversion material, the outside of the nozzle housing 480 can be easily removed without having to provide a large clearance for leaking light between the opening 481 of the nozzle housing 480 and the nozzle lid 600. The nozzle lid 600 located at the front can be illuminated. Thereby, the inside of the nozzle housing part 480 can be sterilized with the sterilizing light while more reliably preventing urine etc. from entering from between the opening 481 of the nozzle housing part 480 and the nozzle lid 600. The user can visually experience the

As shown in FIG. 15(b), the illumination unit 700 may irradiate sterilization light containing an ultraviolet light component and a visible light component. In this way, by irradiating sterilization light containing an ultraviolet light component and a visible light component from the illumination unit 700 provided inside the casing 400, another illumination unit 750 etc. that irradiates light containing a visible light component can be activated. Even if it is not provided, the user can be made aware that the nozzle housing section 480 is being sterilized with the sterilizing light.

In this case, the nozzle lid 600 preferably has a transmitting section 610 that can transmit visible light components. The transmittance of the visible light component of the transmitting portion 610 is higher than the transmittance of the visible light component of the front surface 400a of the casing 400, for example. The illumination section 700 can illuminate the nozzle lid 600 by transmitting visible light components in the transmission section 610.
