Further, the slope gradient of the front wall portion of the frame portion that extends from the front edge of the display window to the front edge of the opening portion is such that the rear edge of the display window extends to the rear edge of the opening portion. It is made smaller than the inclination gradient of the wall part on the back side of the frame part extending to the side.

  According to said structure, the front-back space | interval of the front edge of an opening part and the front edge of a display window can be enlarged in the front side of a display part. Therefore, when the user stands at the front side of the washing machine and looks at the display unit, the front end portion of the display unit can be prevented from being hidden by the front edge portion of the display window. In addition, since the front-rear distance between the rear edge of the opening and the rear edge of the display window can be reduced, the size of the display window does not increase more than necessary.

  According to the present invention, it is possible to provide a washing machine that can be operated by a user with an operation button provided on an upper lid while suppressing a complicated structure of the upper lid and a decrease in operability of the upper lid. Can do.

Since the 1st drain hole 263 is formed in the front-end | tip of the front wall part 261a of the frame part 261, it is hard to see the 1st drain hole 263 from the user who stood in front of the fully automatic washing machine 1. FIG.

  FIG. 7A is a diagram showing a state when the second power button 240 is pressed with the upper lid 15 closed, and FIG. 7B is a second start button with the upper lid 15 closed. It is a figure which shows a mode when 250 is pressed down.

  As shown in FIGS. 7A and 7B, in the state where the upper lid 15 is closed, the first power button 301 is located immediately below the second power button 240, and the first start is directly below the second start button 250. Button 302 is located.

  As shown in FIG. 7A, when the second power button 240 is pushed down, the pressing body 242 protrudes downward from the bottom surface of the upper lid 15, and the lower surface 242 b of the pressing body 242 contacts the pressing pad 301 a of the first power button 301. The pressing button 301b of the first power button 301 is pressed down by touching. The power switch element 402 is pushed by the lowered push button 301b. Thereby, the power is turned on when the fully automatic washing machine 1 is not turned on, and the power is turned off when the power is turned on.

  On the other hand, as shown in FIG. 7B, when the second start button 250 is pushed down, the pressing body 252 protrudes downward from the bottom surface of the upper lid 15, and the lower surface 252 b of the pressing body 252 is the pressing pad of the first start button 302. The press button 302b of the first start button 302 is pressed down in contact with 302a. The start switch element 403 is pushed by the lowered push button 302b. Thereby, when the washing operation is not performed, the washing operation is started, and when the washing operation is performed, the washing operation is interrupted.

  Since the power supply is often shut off before the washing operation is performed, the first power button 301 is often operated every time the washing operation is performed. The first start button 302 is operated every time a washing operation is performed. Therefore, the operation frequency of the first power button 301 and the first start button 302 is higher than the operation frequency of the course button 303, the bath water button 304, and the dehydration button 305.

  In the present embodiment, the second power button 240 and the second start button 250 provided on the upper lid 15 can be used to perform power on / off operation and start / pause operation with the upper lid 15 closed. Moreover, since the operation unit 16 including the power switch element 402 and the star switch element 403 is provided on the upper surface plate 12 side, it is not necessary to perform an electrical wiring process inside the upper lid 15, and the weight of the upper lid 15 is increased. Is also suppressed. Therefore, it can suppress that the structure of the upper cover 15 becomes complicated, and that the operativity of the upper cover 15 falls.

  Moreover, in the said embodiment, the 2nd power button 240 and the 2nd start button 250 corresponding to the 1st power button 301 and the 1st start button 302 with high operation frequency are provided in the upper cover 15, and the operation button with low operation frequency is provided. Since the operation button corresponding to is not provided on the upper lid 15, it is possible to prevent the structure of the upper lid 15 from being complicated and the weight of the upper lid 15 from being increased by providing many operation buttons.

  Further, in the present embodiment, the second power button 240 and the second start button 250 have the pressing bodies 242 and 252 formed as separate members from the button body 241 and 251. The area of the lower surfaces 242b and 252b can be increased by increasing the diameter, and the load on the first power button 301 and the second power button 302 can be reduced.

  In addition, when the pressing bodies 242 and 252 are not separate members but are formed integrally with the button bodies 241 and 251 by resin molding, it is difficult to increase the outer diameter of the pressing bodies 242 and 252. If the pressing bodies 242 and 252 have a hollow structure, holes extending to the pressing bodies 242 and 252 are formed on the surfaces of the button bodies 241 and 251, and if the pressing bodies 242 and 252 have a solid structure, the button bodies 241 and 251 This is because sink marks are likely to occur on the surface, and in any case, the appearance quality of the second power button 240 and the second start button 250 is likely to deteriorate.

  Furthermore, in the present embodiment, the second power button 240 and the second start button 250 have the pressing bodies 242, 252 formed of a softer material than the button bodies 241, 251. It is possible to suppress the first power button 301 and the first start button 302 from being damaged by the pressing bodies 242 and 252 that are in contact with each other while suppressing the damage of the H.251.

  Further, in the present embodiment, the second power button 240 and the second start button 250 have the lower surfaces 242b and 252b of the pressing bodies 242 and 252 formed in a convex curved surface shape. It is possible to further suppress the button 302 from being damaged by the pressing bodies 242 and 252 that are in contact with each other.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications other than those described above can be made to the embodiments of the present invention. .

  For example, in the above embodiment, the upper lid operation unit 200 is provided with the second power button 240 and the second start button 250. However, only one of the second power button 240 and the second start button 250 may be provided on the upper lid operation unit 200. In addition, at least one of the second power button 240 and the second start button 250 and the operation buttons of the operation unit 16 other than the first power button 301 and the first start button 302, for example, the first power button 301 and the first start button. An operation button may be provided on the upper lid operation unit 200 in order to operate the course button 303 that is considered to have the highest operation frequency next to 302.

  In the above embodiment, the operation unit 16 is provided to the right of the insertion port 14 in the top plate 12. However, the operation unit 16 may be provided in front or left of the insertion port 14 in the top plate 12.

  Furthermore, in the above embodiment, the second power button 240 and the second start button 250 are made of a material whose pressing bodies 242 and 252 are softer than the button bodies 241 and 251. However, the pressing bodies 242 and 252 may be formed of the same material as the button bodies 241 and 251.

  Furthermore, in the above embodiment, the lower surfaces 242b and 252b of the pressing bodies 242 and 252 are formed in a convex curve shape, but the lower surfaces 242b and 252b of the pressing bodies 242 and 252 do not have to be formed in a convex curve shape. For example, the lower surfaces 242b and 252b of the pressing bodies 242 and 252 may be flat. However, in this case, in order to suppress damage to the first power button 301 and the first start button 302, it is desirable that the peripheral portions of the lower surfaces 242b and 252b are chamfered into an R surface or a C surface.

  Further, in the above embodiment, the frame portion 261 is formed such that the front wall portion 261a has a smaller slope than the rear wall portion 261b, and the left wall portion 261c has a smaller slope than the right wall portion 261d. . However, the left wall portion 261c may be formed to have the same inclination gradient as the right wall portion 261d as long as at least the front wall portion 261a has an inclination gradient smaller than that of the rear wall portion 261b.

  Further, in the above embodiment, the display window 260 is provided in the upper lid operation unit 200. However, the display window 260 may not be provided in the upper lid operation unit 200.

  Furthermore, in the said embodiment, although the outer tank 20 and the washing | cleaning dehydration tank 21 incline ahead, these do not need to incline.

  Furthermore, although the fully automatic washing machine 1 of the said embodiment is not provided with the drying function, this invention can also be applied to the fully automatic washing machine provided with the drying function.
