Description
Technical field
The utility model relates to faucet, in particular to a kind of constant temperature of water heater valve.
Background technique
Family life mainly passes through electric heater with hot water and is heated to obtain to municipal water supply at present.Due to the specific heat of water
Appearance is higher, while the power of electric heater is limited by Electrical Safety, so general electric heater can all have a water storage cavity.
It needs to heat the water in water storage cavity before use, reaches higher temperature, remix certain proportion when then using
Cold water, be in leaving water temperature in the comfort zone of human body.For the adjustment of water temperature, either using double the dual control fire hose
Water temperature all once can not be adjusted to suitable temperature by combustion taps by head, or list, and is had to pass through continuous temperature and surveyed
Examination and adjustment, could obtain suitable temperature, so quite inconvenient and quite time-consuming.In addition, with the water discharging time of tap
And flow increases, the temperature of hot water can also be reduced with the injection of cold water, led to the water temperature drop of water outlet and be subcooled, then use
Person must adjust the ratio of hot water or cold water again, and being adjusted to the ratio of hot water or cold water repeatedly can make water temperature neglect cold neglect
Heat and cause using upper discomfort and inconvenience.Occur the Thermostatic water heaters of electric-controlled type accordingly.
If Chinese patent (patent No. 201110396052.1) provides a kind of thermostatic faucet of electric water heater, which passes through
Leaving water temperature is adjusted in thermostatic valve core, so that leaving water temperature is in temperature constant state, while by driving unit to thermostatic valve core
It is controlled, the leaving water temperature of regulating thermostatic spool, is realized for the automatically controlled of valve body.In actual water utilizing process, the head of a household is used
Use habit since long is more partial to directly control water flow using mechanical flow switch, so shower is general
Mechanical flow switch will be connected.When using this faucet in this way, after mechanical flow switch closes cutting water flow,
User also needs to control constant temperature driving unit by circuit board, it is made to stop working.In this way to completely close the electricity
Constant temperature of water heater faucet needs to be divided into two steps, is first switched off mechanical faucet, and it is single then to control constant temperature driving by circuit board
Member power-off stops working.Since the constant-temperature tap mixing water chamber is provided with temperature sense probe, temperature sense probe can be to mixed
The temperature for closing water chamber detect and water temperature signal is fed back to circuit board, and then circuit board is by constant temperature driving unit to perseverance
The set temperature of warm spool is adjusted.If not making constant temperature driving unit stop working in the case where turning off mechanical switch,
As the water temperature of mixing water outlet reduces, constant temperature driving unit can drive thermostatic valve core to rotate to the raised direction of temperature, work as perseverance
When warm valve core rotation is to extreme position, stuck phenomenon can occur for valve rod, and constant temperature driving unit can be permanent still in working condition at this time
Warm driving unit connection power supply but can not normal rotation, this will lead to the damage of constant temperature driving unit.
Utility model content
