The object 3 to be cleaned, such as tableware, is set in the tableware basket 4 and stored in the cleaning tank 2, and after the user puts in the detergent, the front opening 5 of the cleaning tank 2 is closed by the door 6 and the operation is started. To do.

  The door body 6 is in close contact with the main body and prevents leakage of cleaning water. When closing the door body 6, it is necessary to lift the front end of the door body 6 opened forward and to hold the door body 6 with a certain force in order to lock the door body 6 to the main body 1. At this time, in the configuration of the first embodiment, since there is one door body 6, the upper part of the door body 6, that is, the upper part of the dishwasher is pushed. That is, when the back surface of the main body 1 is not installed along the wall, the front portion of the main body 1 is lifted up and easily tilts backward. In particular, when the dishwasher has been downsized for a small number of people, not only the weight of the main body but also the amount of the object to be cleaned is reduced, the overall weight is reduced and the front part is easily lifted.

  In addition, this situation becomes remarkable when a pipe housing portion 16 for housing the water supply hose 12 and the drainage hose 13 is provided at the lower rear portion of the main body 1. In such a case, in the configuration of the first embodiment, since the substantially L-shaped tilt preventing member 14 is provided at the rear lower part of the main body 1, the main body 1 is supported behind the rear leg as shown in the conventional example. be able to. That is, even if the front upper portion of the door body 6 is pushed when the door body 6 is closed, it is possible to prevent the front portion of the main body 1 from floating and tilting backward, and consideration such as supporting the main body 1 by hand. Can be made unnecessary.

  The shape of the tilt preventing member is not particularly limited as long as it is a member configured to prevent tilting backward.
