[0003] Further, the drain pipe of the water receiving box is connected with the total exhaust pipe in the water purifier through the exhaust pipe, and the total exhaust pipe is also connected with the hot water tank to realize overall exhaust. When the drain pipe is blocked for a long time, the residues of the kitchen waste will ferment in the drain pipe to produce peculiar smell. These peculiar smells may enter the total exhaust pipe through the exhaust pipe and then backflow into the hot water tank to affect the taste of the hot water. SUMMARY
[0004] The utility model wants to solve the technical problem that the hot water tank of the prior art water purifier is affected by the peculiar smell of the drain pipe, and provides a water purifier.
[0005] The utility model solves the above technical problem by the following technical scheme:
[0006] A water purifier comprises a hot water tank, a water receiving box, a total drain pipe communicated with the hot water tank and the water receiving box, and a total exhaust pipe communicated with the hot water tank and the water receiving box.
