When viewed from below, the irradiation section 52 is exposed in front of the top surface of the rim section 23 (see FIG. 1) located at the rear of the toilet main body 2 (see FIG. 1). The irradiation port 52a of the irradiation unit 52 is arranged so that the illumination light L directed toward the rear area A1 (see FIG. 3) inside the bowl portion 21 (see FIG. 1).

Note that, for example, in the case where a flat shelf is formed between the bowl surface 21a and the rim part 23 in the bowl part 21, the irradiation port 52a of the irradiation part 52 is located between the shelf part and the rim part. It is arranged so that the boundary part with 23 is irradiated.

<Illumination mode by lighting means>
Next, the illumination mode by the illumination means 5 will be explained with reference to FIGS. 3 to 5. FIG. 3 is a schematic perspective view showing an example of an illumination mode by the illumination means 5. As shown in FIG. FIG. 4 is an explanatory diagram of the color temperature of the illumination light L. FIG. 5 is a schematic perspective view showing another example of the illumination mode by the illumination means 5.

The illumination means 5 emits illumination light L so as to illuminate the toilet bowl body 2 (or the periphery of the toilet bowl body 2 as described later).

As shown in FIG. 3, the illumination means 5 irradiates the illumination light L (see FIG. 2) so as to illuminate the rear area A1 inside the bowl portion 21. As shown in FIG. That is, the illumination means 5 illuminates the rear area A1 inside the bowl part 21.

Here, the illumination means 5 emits warm-colored illumination light L. The warm illumination light L is reddish (for example, orange) light with a low color temperature, and as shown in FIG. 4, it is light with a color temperature of 2000 to 3500 K (Kelvin). The color temperature of the illumination light L emitted by the illumination means 5 is preferably 2200K. Note that light with a high color temperature is bluish, and for example, light of 6200 to 6500K is cold-colored light.

In this way, in the flush toilet 1 according to the embodiment, since the illumination light L from the illumination means 5 is warm-colored light, it is possible to prevent the user from waking up by seeing the illumination light L when urinating at night, etc. Can be done. Specifically, it is possible to prevent the user from becoming dizzy after seeing the illumination light L and from being unable to sleep after using the toilet. That is, while realizing illumination of the toilet bowl main body 2, it is possible to suppress disturbing the user's sleep.

Furthermore, since the illumination light L from the illumination means 5 is a warm-colored light (with a color temperature of 2000 to 3500K), it is possible to prevent the user from being woken up by the illumination light L when urinating at night or the like. Thereby, it is possible to realize illumination of the toilet bowl main body 2 while preventing the user's sleep from being disturbed.

In addition, since the illumination means 5 illuminates the rear area A1 inside the bowl part 21, the bowl part 21 can be illuminated widely and clearly, so that the user can easily recognize the bowl part 21, Since the user is prevented from waking up by seeing the illumination light L when urinating at night, it is possible to prevent the user's sleep from being disturbed.

Also, here, the control unit 43 (see FIG. 1) changes the illumination light L (see FIG. 2) emitted from the illumination means 5 to a warm color according to the time. The control unit 43 controls the illumination means 5 to illuminate with warm-colored illumination light L at night. In this case, the control unit 43 uses, for example, the learning function of the toilet seat heating function in the sanitary washing device 4 to store a predetermined time period (for example, from 18:00 to 6:00 the next day) as night time, and stores this time period as night time. For the band, the illumination light L is changed to a warm color.

Furthermore, for example, the user may himself or herself set a predetermined time period during the night. In this case as well, the control unit 43 changes the illumination light L to a warm color during this time period.

In this way, by changing the illumination light L to a warm color according to the time, specifically, by changing the illumination light L that illuminates the toilet bowl body 2 to a warm color at the time when the user goes to bed (at night), It is possible to prevent the user from waking up by seeing the illumination light L when urinating or the like. Thereby, it is possible to realize illumination of the toilet bowl main body 2 while preventing the user's sleep from being disturbed.

As shown in FIG. 5, the illumination means 5 may further emit illumination light L (see FIG. 2) so as to illuminate the left and right side areas of the toilet bowl body 2. That is, the illumination means 5 may further illuminate the left and right side areas A2 of the toilet bowl main body 2.

In this case, for example, the illumination means 5 is housed in the space formed between the deodorizing unit 44 and the bottom wall 453 in the compartment 45 with the irradiation part 52 facing forward, as described above, and is placed inside the toilet main body 2. Illumination light L is irradiated to the left and right side areas A2 of the toilet bowl main body 2 from holes formed in the side surfaces through which the illumination light L can pass. Note that the illumination means 5 is not limited to this, and the illumination means 5 may be one in which the irradiation parts 52 are arranged on the left and right sides of the toilet main body 2, for example.

Even in such a lighting mode, since the illumination light L from the illumination means 5 is warm-colored light, it is possible to prevent the user from waking up by the illumination light L when urinating at night, etc. It is possible to prevent the user from being unable to sleep after using the toilet because the user's eyes are distracted when they see the toilet. That is, it is possible to realize illumination around the toilet bowl main body 2 while preventing the user's sleep from being disturbed.

Furthermore, by illuminating the left and right side areas A2 of the toilet bowl main body 2, the illumination means 5 can make the user easily recognize the toilet bowl main body 2, and the user can use the illumination light L when urinating at night. This prevents the user from waking up, thereby preventing the user's sleep from being disturbed.

<Modified example of flush toilet>
Next, a modification of the flush toilet 1 will be described with reference to FIG. 6. FIG. 6 is a schematic side view showing a flush toilet 1A according to a modified example.

As shown in FIG. 6, the flush toilet 1A according to the modification is a so-called wall-mounted flush toilet that is attached to the wall surface WS of the toilet room TR.

The lighting means 5 is arranged, for example, below the drain trap section (drain trap pipe), and illuminates the bottom of the toilet main body 2, that is, the floor surface FS in a warm color (with a color temperature of 2000 to 3500K, preferably 2200K). Illuminate with light. Also, in the flush toilet 1A according to the modified example, similarly to the above, the control unit 43 (see FIG. 1) changes the illumination light L (see FIG. 2) emitted from the illumination means 5 to a warm color according to the time. do.

Also in the flush toilet 1A according to such a modification, since the illumination light L from the illumination means 5 is warm-colored light, it is possible to prevent the user from waking up by seeing the illumination light L when urinating at night, etc. Can be done. Specifically, it is possible to prevent the user from becoming dizzy after seeing the illumination light L and from being unable to sleep after using the toilet. That is, while realizing illumination of the toilet bowl main body 2, it is possible to suppress disturbing the user's sleep.

Furthermore, since the illumination light L from the illumination means 5 is a warm-colored light (with a color temperature of 2000 to 3500K), it is possible to prevent the user from being woken up by the illumination light L when urinating at night or the like. Thereby, it is possible to realize illumination of the toilet bowl main body 2 while preventing the user's sleep from being disturbed.

Furthermore, by illuminating the lower region A3 of the toilet bowl main body 2, the illumination means 5 can illuminate the user's feet. Since the user is prevented from waking up upon seeing L, the user's sleep can be prevented from being disturbed.

In addition, by changing the illumination light L to a warm color according to the time, specifically, by changing the illumination light L that illuminates the toilet bowl body 2 to a warm color at the time when the user goes to bed (at night), it is possible to change the illumination light L to a warm color when urinating at night. It is possible to prevent the user from waking up upon seeing the illumination light L. Thereby, it is possible to realize illumination of the toilet bowl main body 2 while preventing the user's sleep from being disturbed.

Further advantages and modifications can be easily deduced by those skilled in the art. Therefore, the broader aspects of the invention are not limited to the specific details and representative embodiments shown and described above. Accordingly, various changes may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
