Deng.As shown in Fig. 2, this method may comprise steps of：
In step S210, the water supply pressure of the dish-washing machine is obtained.
In step S220, judge whether water supply pressure reaches hydraulic pressure threshold value.
In step S230, when the water supply pressure reaches hydraulic pressure threshold value, the main heater circuit is allowed to be in work
State.When water supply pressure reaches hydraulic pressure threshold value, show there can be enough water to be fed into the liner of dish-washing machine at this time, this
When main heater circuit can will not be caused to overheat and damage each component or initiation in main heater circuit shower water normal heating
The safety problems such as on fire, therefore main heater circuit can be allowed in running order, if necessary to be heated to shower water, can connect
Other controls switch of main heater circuit makes heater circuit in running order.Or it may be designed in without using other controls
Switch, and make heater circuit in running order when water supply pressure reaches hydraulic pressure threshold value, but be unfavorable for main heater circuit in this way
Flexible control.
In step S240, when the water supply pressure reaches hydraulic pressure threshold value, the secondary heater circuit is not allowed to be in work
Make state.Secondary heater circuit is commonly used in except other miscellaneous functions heated to shower water, these miscellaneous functions are usually washing the dishes
In machine liner it is anhydrous in the state of work, such as when carrying out high-temperature steam sterilization, if water spray will influence Disinfection Effect, when
When drying the dish in internal cavity of bowl washer, there can not be water ejection with heated-air drying.Therefore, if water supply pressure reaches hydraulic pressure
Threshold value then shows may there is water ejection in internal cavity of bowl washer at this time, and secondary heater circuit is not allowed to work at this time, on the one hand can be prevented
The only unnecessary waste of electricity, the interference being on the other hand also avoided that between main heating function and miscellaneous function improve dish-washing machine
Working efficiency.
In step s 250, when the water supply pressure is less than the hydraulic pressure threshold value, do not allow at the main heater circuit
In working condition.When water supply pressure is less than hydraulic pressure threshold value, show water shortage in internal cavity of bowl washer, at this time if at main heater circuit
In work clothes state, it will main heater circuit is caused to overheat.When not allowing main heater circuit in running order, even if connecting main add
Other controls switch of heater circuit, main heater circuit can not also be heated.
In step S260, when the water supply pressure is less than the hydraulic pressure threshold value, the secondary heater circuit is allowed to be in
Working condition.Show do not spray water in internal cavity of bowl washer water or only minimal amount of water ejection, other auxiliary for not needing to water at this time
Function can enter working condition.When allowing secondary heater circuit in running order, if necessary to use corresponding auxiliary work(
Corresponding secondary heater circuit can be connected, when not needing to using miscellaneous function, corresponding secondary heater circuit can also be disconnected.
