Hot merit energy, thus washing when water will be heated, but heat during power consumption be it is very big, roller washing machine
Power consumption about 80% carrys out self-heating.With growth in the living standard and the change of awareness of saving energy, increasing user is installed additional too
It is positive can water heater, also some users washing machine is directly connected to intake pipe of washing machine on water heater pipeline, can so use
Hot water is done washing, and saves the energy, improves clean, but is because that the temperature fluctuation of solar water heater is very big, when some
Wait and be even up to close to 100 degree, if such water is proceeded directly in washing machine, it may appear that in many problems, such as washing machine
Many parts hold and can't stand so high temperature, it may appear that the problems such as deformation leak, can also greatly accelerate it is aging, in addition this
The water of high-temperature is applied directly on clothes, and many clothes will sustain damage, and cause damage.
The washing machine of washing-machine market has the product with cold and hot pair of water intaking valve on a small quantity at present, has cold on existing product panel
Water valve, hot water valve water inlet are selected, and user selects which type of water intaking valve is just selected with user so in program operation process by hand
The water intake mode water inlet selected, no inflow temperature auto-adjustment control in system, so if user is in the feelings for not knowing water temperature
Hot water water inlet is have selected under condition, will be gone wrong.Formerly the double inlet washing machines of patent CN03259135.7, disclose one kind
Double water inflow type washing machines, including motor, interior bucket, outer barrel, electronic process controller and control panel, it is characterised in that water inlet is provided with
