Description
Technical field
It the utility model is related to a kind of steam box microwave oven all-in-one machine.
Background technology
With the raising of people's quality of the life, kitchen appliance is increasingly abundanter, micro-wave oven, baking box, steam box etc. all gradually into
For kitchen appliance product necessary to family life.In order to save kitchen space, there is now will steam the steam box of function and microwave function combination
Microwave oven all-in-one machine.
Existing steam box microwave oven all-in-one machine, steam generating system, microwave generation system are arranged under cooking chamber furnace chamber
Portion, this topology layout are not quite reasonable, can make steam box microwave oven all-in-one machine overall volume larger first, and steam generation system
System includes water route and steam, and microwave generating apparatus then needs to work under high-tension electricity, therefore easily produces mutual shadow between the two
Ring and disturb, be unfavorable for complete machine use.

All have higher requirements, i.e., can not use pure water or high hardness water, this causes the use of steam box by a definite limitation, to user with
Inconvenience is carried out.With the embedded cooking equipment for steaming function, the principle of its generation steam is：The water of water tank passes sequentially through two-way
Pump, magnetic valve, steam is produced into heater, caused steam is cooked into cooking space.Culinary art terminates post-heater
Unnecessary water back through magnetic valve, two-way pump, is recovered to water tank again, the difficult point of this system be how low cost, it is accurate reliable
Control heater water level.Water level control is bad to occur following two situations：First, when heater water is very few not
It can add water that heater dry combustion method phenomenon occurs in time, niff occurs in dry combustion method, while influences heater life, heater
Easy burn-out；Second, when adding water excess, water spills into cooking space, or even water flows out immersion user man cabinet etc. from cooking space.
In the existing cooking equipment with steaming function, the water level of heater is controlled mainly by following two modes：
First way：Control heater water level is simulated by program, when the method is according to pump capacity control plus water
Between, a temperature sensor is arranged in heater base in addition, obtains adding coolant-temperature gage by experiment test, when sensor temperature height
Just add water when coolant-temperature gage is added, avoid the occurrence of dry combustion method phenomenon, but because hysteresis quality occurs in the feedback of temperature sensor signal,
Therefore dry combustion method phenomenon occurs in heater in the same old way；The change of other pump capacity, the individual difference fluctuation of heater power, also has
The high easy scaling of local heater of water hardness, there is incrustation scale that heater heat transfer can be caused abnormal, can equally cause such a
Method is not very reliable, and dry combustion method phenomenon is not avoided that, dry combustion method smell occurs, and have considerable influence to heater life.
The second way：The water box connected with heater are designed, pass through water box and heater both sides water surface elevation one
Cause principle controlling water level；Then buoy is provided with water box, it is (logical that the position signalling that liquid level is fluctuated is converted into electric signal
It is often to utilize magnet tongue tube principle), so as to control the height of water level in heater；This mode is also easily by water quality shadow
Ring, when the water hardness is high, the easy scaling of heater base, the water level in such water box and heater, be substantially it is inconsistent,
Also heater is easily made dry combustion method phenomenon occur.
