BACKGROUND OF THE INVENTION
The present invention provides a filter having a bulging portion that is formed in a bulging shape that filters the collected or drained washing water and protrudes downward for storing and holding the collected matter. The present invention relates to a dishwasher mounted so that it can be removed by moving it upward.
[0002]
[Prior art]
Such a dishwasher is used to filter the wash water circulated for washing the objects to be washed such as dishes and the wash water drained after washing with a filter, so that the dirt and residue removed. By removing the washed product from the washing water, the washing and drainage can be performed satisfactorily.
That is, a dishwasher generally includes a washing pump, a washing nozzle, a drain pump, etc., and the washing water supplied and stored in the washing tank is placed from the washing nozzle to the washing tank by the washing pump. The washing water is circulated in a form to be ejected to the object to be washed, and the washed water after washing is drained out of the washing tank by a drainage pump. During the circulation of the water and the drainage of the washing water, the filter acts to filter the washing water, and the washing material removed from the washing water by such filtration action is collected by the filter.
Then, the filter is removed by moving upward from the bottom surface of the cleaning tank at an appropriate time such as after cleaning, and the collected matter is removed and cleaning with hot water is performed.
[0003]
Conventionally, as shown in FIG. 6 (a), such a filter 4 has a bulging portion 14 formed in a bulging shape that protrudes downward for storing and holding the collected matter. And the depth on the other end side are the same depth, and the depth is large. In addition, 15 is a handle part in the figure.
[0004]
[Problems to be solved by the invention]
The conventional filter was formed so that the bulging part had the same depth on the one end side and the other end side, and a large depth, so the filter was moved upward from the bottom surface of the cleaning tank. When removing it, even if it is tilted to avoid contact with other objects such as a cleaning nozzle, it is difficult to spill the collected material, but even in such a tilted state, from above The projected area of the swell increases due to the bulging portion, and there is a problem that it is difficult to handle such as accidentally contacting with another object.
Incidentally, in general, a basket-like mounting body for storing and holding an object to be cleaned is provided in the cleaning tank so as to cover the upper side of the filter. If the projected area is large, it will not be possible to properly store and hold the object to be cleaned by providing an opening for inserting the filter up and down in the basket-like mounting body, and the filter is moved upward. When removing it, there is also the inconvenience that the cage-like mounting body must be removed in advance.
As shown in FIG. 6B, it is conceivable that the bulging portion 14 of the filter 4 is formed shallow, but in this case, the trapped material tends to spill out when the filter 4 is tilted, which is practical. It was difficult.
