As shown in fig. 1 to 6, an embodiment of the present invention provides a spraying structure of a dishwasher,

The shower calandria comprises a shower calandria 1, wherein a water inlet pipe 11 is arranged on the pipe wall on the same side of the shower calandria 1, and a plurality of shower branch pipes 3 are arranged at intervals.

In the invention, a water inlet pipe 11 is arranged on the side wall of one end part of the spray calandria 1, and the water inlet pipe 11 is arranged perpendicular to the length direction of the spray calandria 1. Preferably, the other end of the spray calandria 1 is in a closed arrangement, a plurality of spray branch pipes 3 are arranged on the pipe wall of the spray calandria 1 along the length direction at intervals, and a plurality of spray branch pipes 3 are also vertically arranged with the length direction of the spray calandria 1, wherein the spray branch pipes 3 are consistent with the pipe opening of the water inlet pipe 11.

Will spray calandria 1 sets up on dish washer inner bag wall or shelf, can set up on each turning or lateral wall of dish washer as required to can cooperate the spray arm of current dish washer bottom to carry out all-round spraying to each corner in the dish washer, thereby guarantee that the tableware that is in different positions in the dish washer can all be sprayed and washd, guarantee the washing effect.

In addition, the spray branch pipe 3 on the spray calandria 1 is consistent with the pipe mouth of the water inlet pipe 11. So that it can be ensured that when the spray calandria 1 is installed, the spray branch pipe 3 normally sprays to face tableware, and the water inlet pipe 11 is on the same side as the water inlet pipe, so that the water channel can be conveniently communicated with the water inlet pipe 11.

Specifically, be provided with a plurality of telescopic joints on the inner bag wall of dish washer, if through laying a plurality of ripple hoses on the lateral wall of inner bag, on the pump liquid mechanism of ripple hose's one end and dish washer bottom spray arm, also can set up pump liquid mechanism alone in the water catch bowl of below. Preferably, a plurality of corrugated hoses are arranged as each branch of the bottom spray arm, and the other end is connected with a joint with a valve. When the spraying structure is installed on the inner container wall of the dish washer, the joint position can be adjusted according to the retractility of the corrugated hose and then is in butt joint with the water inlet pipe 11, so that a spraying branch is additionally arranged in the dish washer.

Further, the nozzle of the spray branch pipe 3 is provided with a spray header 31, the end surface of the spray header 31 is provided with a plurality of water outlet holes 311, and the apertures of the water outlet holes 311 gradually increase along the extending direction of the spray branch pipe 3.
