Problems solved by technology

[0003] However, in the conventional dish washer, since the tower nozzle 55 is arranged in the approximate center of the washing nozzle, the tower nozzle 55 is only sprayed by the jet reaction force of the washing water jetted out from the jet port of the tower nozzle 55. type nozzle 55 cannot rotate sufficiently
Specifically, since the jetting reaction force of the washing water jetted out from the jetting port of the tower nozzle 55 is generated at a very short distance from the center of rotation, the generated torque is also small, and the rotation of the nozzle is insufficient.

Abstract

The disclosed dishwasher has a washing tub, a washing pump, a washing nozzle, and a tower nozzle. Items to be washed are placed in the washing tub. The washing pump pressurizes washing water. The washing nozzle is rotatably provided inside the washing tub and sprays washing water pressurized by the washing pump on the items to be washed. The tower nozzle protrudes vertically upward from the center of the washing nozzle and sprays washing water pressurized by the washing pump on the items to be washed. The washing nozzle has a plurality of channels and a valve body. The plurality of channels are each provided with a spray opening. The valve body switches the supply of washing water between the plurality of channels and the tower nozzle depending on changes in the pressure of the washing water supplied from the washing pump. When washing water is sprayed from the tower nozzle, washing water is sprayed from at least one of the plurality of channels in the washing nozzle, causing the washing nozzle to rotate.

Description

technical field [0001] The present invention relates to a dishwasher for washing dishes and the like using washing water. Background technique [0002] In the past, this kind of dish washing machine was Figure 18 the structure shown. (For example, refer to Patent Document 1). Next, the structure of this type of dishwasher will be described. A conventional dishwasher 50 includes a dish basket 51 , a washing tank 52 , a washing pump 53 , a washing nozzle 54 , a tower nozzle 55 , and a water separation and reversing unit 56 . Tableware is stored in the tableware basket 51 . Dish basket 51 is placed in washing tub 52 . Washing pump 53 sends washing water to washing nozzle 54 . Washing nozzle 54 has a plurality of nozzle holes. The cleaning nozzle 54 sprays the cleaning water fed by pressure from a plurality of nozzle holes into the cleaning tank 52 while rotating. The tower nozzle 55 is formed to extend upward from the central portion of the cleaning nozzle 54 . The tow...
