Example 1

Referring to fig. 1 and 2, the anti-siphon respirator of a dishwasher of the present embodiment includes a first housing 1 and a second housing 2, wherein the first housing 1 and the second housing 2 are engaged with each other, and a cavity is formed inside the first housing 1 and the second housing 2. The first shell 1 on set up outlet duct 5, the second shell 2 on set up inlet tube 3 and outlet pipe 4, inlet tube 3, outlet pipe 4 and outlet duct 5 all are linked together with the inside cavity of first shell 1, second shell 2. The water inlet pipe 3 and the water outlet pipe 4 are arranged side by side, the water inlet pipe 3 is connected with the electromagnetic valve through a hose, and the water outlet pipe 4 is connected with the boiler through a hose.

The sealing ring 7 and the ball body 8 are arranged in the inner cavities of the first shell 1 and the second shell 2, the sealing ring 7 is fixed at the lower part of the air outlet pipe 5, the sealing ring 7 is a rubber sealing ring, and the ball body 8 is a plastic ball. The second casing 2 is inside to set up support column 10, and support column 10 top is provided with the step, and the lateral wall of second casing 2 also is provided with the step, and baffle 9 is supported by support column 10 and step to welded fastening. The support column 10 is arranged in the middle of the second shell 2, and the baffle 9 is arranged below the air outlet pipe 5; the baffle 9 cooperates with the first housing 1 to limit movement of the ball 8 over a large area between the outlet duct 5 and the baffle 9. The baffle plate is used for blocking water flow when water just rushes into the inner cavity, so that the influence on the ball body is reduced.

The air outlet pipe 5 is connected with a threaded pipe 6, the threaded pipe 6 is perpendicular to the air outlet pipe 5, the inside of the threaded pipe 6 is communicated with the air outlet pipe 5, and threads are arranged on the outer side wall of the threaded pipe 6.
