The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.
[0015] See attached Figure 1-2 The present application provides a spray system for a dishwasher, which includes an inner tank 1, a water cup 2, a washing pump and a water diversion valve 3. The water cup 2 is arranged at the bottom of the inner tank and is used to collect water in the inner tank. The input end of the washing pump is connected to the water cup 2, and the output end is connected to the water inlet end of the water diversion valve 3. A first spray arm 4 is provided on the inner bottom wall of the inner tank 1, and a nozzle is provided on the upper end surface of the first spray arm. A second spray arm 5 and a third spray arm 6 are provided on the side wall of the inner tank. The second spray arm 5 is provided near the connection between the bottom wall and the side wall of the inner tank. The second spray arm can be set on the bowl basket for use, and the third spray arm The arm 6 is arranged above the middle part of the inner pot 1, and is used for spraying the tableware above and below it. The top wall of the inner pot 1 is provided with a fourth spray arm 7. The water diverter valve 3 is provided with a first water outlet connected to the first spray arm 4, a second water outlet connected to the second spray arm 5, and a third water outlet connected to the third spray arm 6 and the fourth spray arm 7.
