The washing is carried out in 2011, and the water softener includes a resin chamber and a salt chamber, and the water softener is connected to the washing chamber 2011.

Specifically, a salt solution is provided in the salt chamber, and a soft water resin is disposed in the resin chamber to adsorb calcium and magnesium ions flowing into the water in the resin chamber, and the water is softened and then discharged into the washing chamber 2011 to carry out the tableware. The washing is cleaned, whereby the formation of scale in the washing chamber 2011 can be prevented, causing clogging of the sink dishwasher 200, and the cleaning effect of the sink dishwasher 200 can be improved. During the working process of the water softener, it is necessary to periodically introduce regenerating water into the salt chamber, and regenerate water into the salt chamber to form a regenerating salt solution. When the softening property of the soft water resin in the resin chamber is lowered, it is necessary to reduce the soft water resin in the salt chamber. The formed regenerated salt solution enters the resin chamber to regenerate the soft water resin.

As shown in Figures 1-5, a respirator 100 for a sink dishwasher 200 in accordance with an embodiment of the first aspect of the present invention includes a housing. The inner cavity of the casing is provided with a drainage channel 1, a water inlet chamber 2 and an air chamber 3.

The drainage process of the sink dishwasher 200 is such that the washing sewage generated in the washing chamber 2011 enters the drainage channel 1 through the sewage inlet 11 and is discharged into the sewer through the sewage outlet 12, thereby realizing the drainage process of the sink dishwasher 200.

When the drainage process is stopped, a negative pressure is formed in the upstream section of the drainage channel 1, so that the water retained in the downstream section of the drainage channel 1 communicating with the sewer has a tendency to flow back due to siphoning, since the drainage vent 13 and the atmosphere are connected. The air in the atmosphere can enter the drainage channel 1 through the drainage vent 13 to balance the pressure difference in the drainage channel 1 to prevent the siphon phenomenon of the drainage channel 1, thereby preventing the water in the drainage channel 1 from flowing back to the sink after drainage In the washing chamber 2011 of the dishwasher 200, the water retained in the drain passage 1 is smoothly discharged.
