State, the second control switch 115 are in opening state.Outlet component 112 can drive crossover connection by being discharged conversion motor 117
112-2 is rotated, for example, crossover connection 112-2 is made to be rotated by 90 ° counterclockwise（Position can be limited by preset limited post）, so as to make
The apopore 112-4 obtained on outlet pipe 112-1 is overlapped with the through-hole 112-5 on crossover connection 112-2, and water can be through apopore 112-
4th, through-hole 112-5 is flowed out.During this period, third control switch 116 can be controlled to open outlet component according to user's operation
112 so that water discharges or close outlet component 112 from outlet component 112 so that water cannot be discharged from outlet component 112.
In embodiments of the present invention, when system is under whole courage heating mode, if starting transfiguration heating function at this time,
It needs to be converted to half courage heating mode by whole courage heating mode, is described in detail below and half courage is converted to by whole courage heating mode adds
The control method of heat pattern：
Optionally, when heating mode is converted to half courage heating mode by whole courage heating mode, 11 basis of water control unit is passed in and out
The control instruction of microcontroller 12, which automatically controls the inflow and outflow of liner 2, to be included：
Closing second controls switch 115, and detects water temperature in liner 2 using temperature sensor 14, when water temperature is less than in advance in liner 2
If during value, then first is controlled to control switch 114 in opening state, to make to arrange directly outside liner water by opening blowdown component 111
After reaching half courage water level to water level, the second control switch 115 is opened；When water temperature is higher than preset value in liner 2, then first is controlled
Control switch 114 is closed, and liner water is by opening third control switch 116, by being arranged outside outlet component 112 until water
After position reaches half courage water level, the second control switch 115 is opened.
In embodiments of the present invention, as shown in figure 3, when system is converted to half courage heating mode from whole courage heating mode,
Need liner water level being adjusted to the working condition of half courage；Wherein, in order to improve the utilization rate of hot water, it would be desirable to detect liner
Water temperature value, at this time system can open preset intelligent measurement judgment mechanism.When internal system water temperature is relatively low（Such as, it is less than
During preset value）, first controls switch 114 that can open, and opens blowdown component 111, extra cold water can be from row in liner 2
