Next, the operation part 20 of the dishwasher 10 of this embodiment will be described. FIG. 2 is a front view of dishwasher 10 with door 12 closed. As shown in FIG. 2, the operation unit 20 is provided above the window 12a outside the door 12 (on the +Z direction side). 2 also shows an enlarged view of the operation unit 20. As shown in FIG.

The operation unit 20 has, for example, various buttons 21-25 and display units 26-27.
A button 21 is a power button for turning on and off the power. The button 22 is a selection button for selecting an operation mode of the dishwasher 10. In this embodiment, a selection button 22a for selecting the standard mode and a selection button 22b for selecting the UV mode are selected. can include The operating modes of the dishwasher 10 are described below. The button 23a is a reservation button for setting an operation reservation for the dishwasher 10, and the button 23b is a dry keep button for keeping the dishes dry after washing. The button 24 is a selection button for selecting a dish washing course, and in the case of the present embodiment, one of four courses can be selected. The button 25 is a start button for causing the dishwasher 10 to start the operation (mode, course) selected and set by the user. Button 25 may function as a button for pausing operation of dishwasher 10 .

The display unit 26 is a display for displaying information to the user. For example, the scheduled start and/or end time of the operation of the dishwasher 10, the scheduled end time of the operation, and the time required until the end of the operation. etc. can be displayed. The display unit 26 may display functions set by the user (for example, child lock function, dry keeping function, interior cleaning, etc.) and/or requests to the user (for example, water supply). The display unit 27 is a lamp indicating whether or not the various buttons 21-25 have been selected by the user, and is provided for each of the various buttons 21-25.

As described above, the dishwasher 10 of this embodiment has the standard mode and the UV mode as operation modes. The standard mode (second mode) is a mode in which cleaning is performed by the nozzle members 14 (the first nozzle member 14a and the second nozzle member 14b) and ultraviolet irradiation is performed by the lamp 15 (ultraviolet lamp). Irradiation of ultraviolet rays by the lamp 15 can be performed after cleaning by the nozzle member 14 . The standard mode can be selected by pressing the button 22a of the operation unit 20. FIG. On the other hand, the UV mode (first mode) is a mode in which only ultraviolet irradiation is performed by the lamp 15 (ultraviolet lamp) without washing by the nozzle member 14 . The UV mode can be selected by pressing the button 22b of the operation unit 20. FIG. By providing such a UV mode, not only tableware, but also various items such as items that should not be wet with water and/or items that should not be wet with water can be sterilized (removed) by irradiating ultraviolet rays. bacteria treatment, sterilization treatment) can be performed, so the convenience of the dishwasher 10 can be improved.

FIG. 3 shows an example in which articles to be sterilized in the UV mode (hereinafter sometimes referred to as “target articles”) are arranged inside the container 13 . The target article is placed on the placing table 30 arranged inside the container 13 of the dishwasher 10 . The mounting table 30 is, for example, a mesh member. Further, the container 13 is configured such that the mounting table 30 can be placed at each of a plurality of positions with different distances from the ramp 15 (that is, height positions inside the container 13).

FIG. 3A shows an example in which a mounting table 30 on which a relatively thin target article is mounted is arranged inside the container 13 . FIG. 3A exemplifies a mask as the target article. In this case, the mounting table 30 is arranged inside the container 13 while being supported by a support member 13 a (see FIG. 1A ) provided on the inner surface of the container 13 . The support member 13a is configured by, for example, a projection that protrudes from the inner surface of the container 13 and extends toward the inner side (+Y direction side) of the container 13 . By sliding the mounting table 30 along the support member 13 a and inserting it into the container 13 , the mounting table 30 (that is, the target article) can be arranged close to the lamp 15 .

FIG. 3B shows an example in which a mounting table 30 on which a relatively tall target article is mounted is arranged inside the container 13 . In FIG. 3B, a cup is exemplified as the target article. In this case, the mounting table 30 is placed on a basket member 31 for placing tableware, and is arranged inside the container 13 together with the basket member 31 . By arranging the mounting table 30 inside the container 13 in this way, it becomes possible to arrange even relatively tall target articles inside the container 13 .

Here, in the UV mode, the lamp 15 (ultraviolet lamp) may be configured to irradiate the target article with ultraviolet rays for a variable period of time. For example, when the target article is arranged away from the lamp 15 as shown in FIG. 3B, the target article is arranged closer to the lamp 15 as shown in FIG. The intensity of the ultraviolet rays irradiated to the article is low, and it is necessary to lengthen the irradiation time of the ultraviolet rays in order to obtain the same sterilization effect. Therefore, the dishwasher 10 of this embodiment is configured so that the user can set the irradiation time of ultraviolet rays through the operation unit 20 . Thereby, the user can set the irradiation time of the ultraviolet rays so as to obtain the desired sterilization effect. As an example, the dishwasher 10 of the present embodiment is configured such that the UV irradiation time can be switched (selectable) depending on the number of times the user presses the button 22b of the operation unit 20 . Note that the ultraviolet irradiation time can be displayed on the display section 26 of the operation section 20 .

As described above, the dishwasher 10 of the present embodiment has the UV mode in which only the lamp 15 (ultraviolet lamp) irradiates ultraviolet rays without washing with the nozzle member 14 . As a result, it is possible to perform only sterilization treatment (sterilization treatment, sterilization treatment) by irradiating ultraviolet rays to various articles, not limited to tableware, so that the convenience of the dishwasher 10 can be improved. can.

The invention is not limited to the embodiments described above, and various modifications and variations are possible without departing from the spirit and scope of the invention.
