Drinking water machine

The utility model relates to a drinking water machine which can discharge boiled water and warm water. The utility model comprises an inner liner, a heat exchanger, a hot water outlet, a hot water valve, a warm water outlet, a warm water valve and a cold water pipe, wherein the cold water pipe is divided into multiple single-way cold water pipes through a multiple-way valve. The single-way cold water pipes respectively extend to the corresponding hot water valve and the warm water valve, the flow currency and the flow block of the single-way cold water pipes are respectively controlled by the corresponding hot water valve and warm water valve, and the flow currency and the flow block of the single-way cold water pipes are synchronous with the opening and the closing of the hot water outlet and the warm water outlet; the single-way cold water pipes which pass the hot water valve and the warm water valve are combined with the multiple-way valve, forming the single-way cold water pipe which is communicated with an outer pipe on the cold water inlet end of the heat exchanger. The utility model has the advantages of simple and reasonable structural design, energy saving, convenient use, low inner liner bearing pressure intensity and impact force, low cost on complete machines and long service life.
