The detergent container 14 is also integrally formed on the inner surface of the door 3 or attached as a separate member.

[0005]

In the above-described dishwasher, the holding member 20 of the dish basket can be formed integrally with the washing tank 1 when the washing tank 1 is formed of a resin member. Depending on the molding conditions such as the mold of the cleaning tank 1, it is difficult to take a complicated shape and a free configuration (for example, disposing a large number of holding members 20 in the vertical direction). Also,
When the cleaning tank 1 is formed of a metal member such as stainless steel, it is necessary to attach the holding member 20 as separate members to two places on the left and right sides of the cleaning tank 1, which increases the number of parts and the assembly process. Although it is possible to configure the holding member 20 by performing a drawing process on a part of the metal member, in the case of a dishwasher having a configuration in which a plurality of tableware baskets are arranged vertically, a plurality of drawing processes are performed. Difficult to do,
Further, there is a problem that the strength itself of the cleaning tank 1 itself extending in the height direction is also reduced.

On the other hand, the detergent container 14 integrally formed on the inner surface of the door 3 is usually formed in a simple shape with a concave portion on the inner surface of the door, depending on molding conditions such as a mold of the door 3. In recent years, hot water supply type dishwashers characterized by being connected to a water heater have been increasing, but in a hot water type dishwasher, cold accumulated water in piping from the water heater to the dishwasher is supplied to the cleaning tank 1. After the supply, it is usual to perform a drainage operation of the accumulated water in the pipe for once draining. In such a dishwasher, since the detergent container 14 is formed by a simple concave portion, the detergent is spilled into the washing tank 1 when the door 3 is closed and is discharged out of the system when drainage water remaining in the pipe is drained. The discharge water sprayed from the cleaning nozzle when the accumulated water is drained falls on the detergent container 14, causing a problem that the detergent is washed away, and the detergent container needs to be attached as a separate member. Therefore, the present invention integrally forms a plurality of members formed inside the washing tank 1 of the dishwasher,
It is an object of the present invention to provide a dishwasher which not only reduces the number of parts but also secures the strength of a washing tank with only a single structural part and has the function of a plurality of members with a single structural part.
