Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 2, it is a preferred embodiment of the present invention. In the present embodiment, the exhaust system for a water purifier includes a water tank 1 and a hot tank 2, wherein the water tank 1 has a tank body 11, an overflow tank 12, and a cover 15. The above-mentioned container 11 is hollow to form the cavity 10 for holding the normal temperature water, the water inlet end of the hot container 2 is connected with the water outlet end of the cavity 10 in fluid, and there is a heater in the hot container 2, the overflow tank 12 and the container 11 can be different layout forms, the overflow tank 12 in this embodiment is arranged beside the container 11, and the container 11 and the overflow tank 12 are left open on their respective tops, and they are connected and connected with each other near the upper edge of the open, the overflow tank 12 in this embodiment is arranged beside the container 11 and near its front side, and the above-mentioned overflow tank 12 has a steam inlet 14, the steam outlet end of the hot container 2 is connected with the steam inlet 14 in fluid, the steam inlet 14 is arranged on the bottom wall of the overflow tank 12.

Further, in order to ensure that the water tank does not leak water, it is preferable that the water tank 1 further includes a cover 15, and the cover 15 is disposed on the top of the water tank 1 and covers the openings of the tank body 11 and the overflow tank 12. In order to ensure that the condensate impinging on the tank cover can be accurately returned to the overflow tank, the cover 15 has a downwardly extending baffle 16, and the lower end of the baffle 16 is disposed toward the opening of the overflow tank 12. In order to prevent the condensed water with residual temperature from flowing into the tank and causing the temperature of the raw water tank to be too high, it is preferable that the baffle 16 is disposed at the front side of the cover 15, and the lower end of the baffle 16 is protruded into the open mouth of the overflow tank 12 in a state that the cover 15 is covered on the top of the tank 11.
