Further, the water purifier includes a steam return line 8 for returning the steam in the hot tub 9 to the water tank 6. One end of the steam return pipeline 8 is communicated with the upper part of the hot liner 9, and the other end is communicated with the upper part of the water tank 6. When hot courage 9 heats, the high temperature steam in the hot courage 9 can flow back to water tank 6 through steam return line 8, and water tank 6, hot courage 9, steam return line, delivery pump 12 form a closed loop, can avoid the blasting risk that high temperature steam gathers and leads to in the hot courage 9, and the backward flow steam also has the supply and preheats the effect to the cold water of water tank 6. Furthermore, in order to shorten the heating time of the hot liner 9 in the initial heating stage, the safety valve 3 for opening and cutting off the steam return pipeline 8 is further arranged on the steam return pipeline 8, in the initial heating stage, the safety valve 3 is closed, the hot liner 9 is in the closed heating stage, heat is accumulated in the hot liner 9, the water temperature can be quickly heated to a set temperature, the pressure in the hot liner 9 exceeds a safety range, the safety valve 3 can be opened, the hot liner 9 and the water tank 6 are communicated, high-pressure steam in the hot liner 9 is released, and the explosion risk of the hot liner 9 is reduced. The safety valve 3 can be a damping valve, when the difference value between the pressure of the safety valve 3 close to the hot liner 9 and the pressure of the safety valve close to the water tank 6 exceeds a preset threshold value, the safety valve 3 is automatically opened, so that the steam return pipeline 8 is communicated, the upper space of the hot liner 9 and the upper space of the water tank 6 are communicated, the pressure in the hot liner 9 is released to the water tank 6, and the pressure in the hot liner 9 is reduced.

In another embodiment, the safety valve 3 may be an electric control valve, and the water purifier further includes a control board for electrically controlling the on/off of the safety valve 3. After the water outlet structure 1 stops discharging hot water for a preset time, the control panel controls the safety valve 3 to be opened so that the hot liner 9 is communicated with the water tank 6 through the steam return pipeline 8, and therefore the air pressure in the hot liner 9 is released quickly. Further, the water purifier can automatically control the reversing valve 30 to be communicated with the second outlet end, the water outlet structure 1 is communicated with the hot liner 9, and water in a pipeline between the water outlet structure 1 and the hot liner 9 can flow back to the hot liner 9 by means of self gravity. The water in the pipeline between the hot liner 9 and the water outlet structure 1 can be enabled to completely flow back to the hot liner 9, and the problem that the temperature of the first cup of hot water taken at certain intervals can not meet the requirement due to the fact that the water in the water outlet structure 1 cannot completely flow back to the hot liner 9 can be solved. The on-off of the safety valve 3 is controlled through the control panel, water in the water purifier which stops discharging hot water within the preset time is totally returned to the hot container 9 from the hot container 9 to the water discharging structure 1, and the requirement for water temperature can be met by a first cup of hot water which is taken after the preset time is guaranteed.
The control board is also used to control the operations of the booster pump 14 and the transfer pump 12, and the water level in the water tank 6 can be adjusted by controlling the operations of the booster pump 14 and the transfer pump 12. It will be appreciated that the depth to which the heat exchange line 5 is immersed in the cold water determines the amount of heat exchange and thus the outlet water temperature, in order to provide a greater choice of outlet water temperature. Further, the first hot water mode further comprises a plurality of outlet water temperature gears, the control board prestores the water levels of the water tanks 6 corresponding to the different outlet water temperature gears, that is, the different water tank water levels basically determine the water temperatures output by the heat exchange pipeline 5, and the control board controls the operation of the booster pumps 14 and the delivery pumps 12 according to the selected outlet water temperature gears to adjust the water tanks 6 to the water levels matched with the water tanks.
