Fastened with (screw) 80.

  The operation and action of the drum type washing machine configured as described above will be described below.

  First, when the user pulls out the detergent charging case 53 to put the detergent, the detergent charging case 53 is located at the upper front of the washing machine body 50. This is a natural motion, and an inclined portion 67 formed in a gentle slope is formed on the extended line of the motion, and the box 68 opened upward is naturally caught by hands, resulting in a natural motion and detergent. The charging case 53 can be pulled out.

  Further, for example, when the user stores the detergent charging case 53 halfway in the storage portion 65 and starts operation with the detergent protruding case 53 protruding from the front frame 51, the detergent is poured into the water supply valve 63. Although there is an increased risk of water leaking out of the washing machine main body 50 from the charging case 53 and abnormal noise occurring during the high speed rotation of the rotary drum 57, according to the present embodiment, the front surface of the detergent charging case 53 is Since it is configured so as to be flush with the front surface of the front frame 51 in the stored state, it can be easily recognized visually if the front surface of the detergent charging case 53 is displaced, and can be reinserted correctly. Water leakage and abnormal noise due to incomplete storage of the charging case 53 can be prevented in advance.

  The front surface on which the detergent charging case 53 is arranged is an inclined surface that recedes upward together with a door 59 that opens and closes an opening 58 provided on the upward inclined surface.

  The inclined portion 67 on which the finger is hung is disposed in a region that forms the top surface of the front upper portion of the washing machine main body 50, and is not conspicuous from the front surface of the washing machine main body 50. Therefore, there is no need to provide a handle for pulling out the detergent charging case 53 on the front surface of the main body, so that the dividing lines on the front surface of the main body can be reduced, and the design can be improved.

Here, the fact that the inclined portion 67 is in an inconspicuous position from the front surface of the washing machine main body 50 means that the inclined portion 67 is used for a wheelchair user whose line of sight is low or a user who is used in a dark place. Will be directly invisible. However, by providing the box body 68 that opens upward at a position corresponding to the inclined portion 67, the user should be able to recognize and easily use the range to be handled.

  The detergent charging case 53 is mainly composed of a decorative plate 69 that forms a part of the front side of the washing machine body 50 in an inclined surface, and a box 68 for engaging the detergent charging portion 64 and the user's finger. Each member is made of a plastic resin molded product, and each member can be processed in a simplified manner.

By taking this, a strong bond that can withstand repeated use can be obtained.

  Here, if the boss 73 is formed on the box 68, the box 68 is separated from the front surface of the washing machine main body 50, and the size of the box 68 is small, so that the boss 73 can be easily configured by sliding it downward. Further, the fastening portion 72 of the decorative plate 69 can be easily configured with a small slide removal range.

  That is, the detergent case 53 is divided into three members, a decorative plate 69, a detergent charging part 64, and a box 68, and a boss 73 formed by a mold slide having a large structure on the box 68 which is a relatively small member. The decorative plate 69, which is a member having a slightly larger shape, is formed with a fastening portion 72 that is an undercut on the resin-molded mold, so that the sliding range is small and the processing of the member is very simple. .

  Further, when the detergent charging case 53 is stored, if a finger is placed outside the range of the inclined portion 67 that secures a clearance for the finger, the finger is naturally sandwiched between the storage portion 65. become. However, the range in which the user should reach his / her hand is limited by the rear wall 74 and the side wall 75 of the box body 68, and even if the hand is reached into the box body 68 in a groping state, a finger is sandwiched between the storage unit 65. It is also possible to prevent the unexpected situation.

  That is, in the state in which the detergent charging case 53 is stored, a box 68 opened upward corresponding to the inclined portion 67 is provided on the back surface side of the decorative plate 69, so that the detergent charging case 53 can be connected to the storage unit 65 when stored. It is possible to prevent unforeseen situations such as pinching your fingers between them.

  Further, in the storage state of the detergent charging case 53, a gap must be provided between the box body 68 and the inclined portion 67 so that the decorative plate 69 is easily flush with the front frame body 51. If the upper end surface 83 of the rear wall 74 protrudes from the surface of the inclined portion 67, the user's nails may not only hit the upper end surface of the rear wall, but the user's nails may enter this gap and feel painful. There is also. However, the upper end surface 83 of the rear wall 74 of the box body 68 into which the finger is inserted is covered by the inclined portion 67 so as to be continuous with the inclined portion 67 of the top plate portion 54 and not to protrude above the inclined portion 67. Therefore, even when the user inserts his / her finger into the box body 68 along the inclined portion 67, the finger slides inward of the rear wall 74 without being caught by the upper end surface 83 of the rear wall 74. The detergent charging case can be pulled out without a sense of incongruity by hanging on the front wall 84 of the box 68.
