Technical solution be clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Intelligent appliance in the application can be to scorch all-in-one machine, but be not limited to scorch all-in-one machine.It will scorch in all-in-one machine
Water level detecting temperature sensor delete, not only optimize interiors of products space, improve machine inner space utilization rate.And it is steaming
The first temperature sensor and second temperature sensor are respectively set on vapour generator, it is current by three kinds of different judgment method detections
It scorches whether all-in-one machine is in exsiccosis, and user is prompted to fill the water to sink, prevent steam deficiency from influencing food cooking effect,
To increase substantially the stability and reliability of product.
To be described in detail to the embodiment of the present invention below convenient for understanding the present embodiment.
Embodiment one:
Fig. 1 is the water shortage detection method flow chart for the intelligent appliance that the embodiment of the present invention one provides.
Referring to Fig.1, method includes the following steps:
Step S101 obtains selection operation of the user in the operation interface of intelligent appliance, and selection operation includes steaming mode；

Whether all-in-one machine is in exsiccosis；
Second situation: detect that second surface temperature is T at 2 milliseconds3, detect that second surface temperature is at 4 milliseconds
T4, T4-T3/ t is climbing speed Δ v2, judge climbing speed Δ v2Whether the first upper limit value is greater than, so that it is determined that scorching all-in-one machine
Whether exsiccosis is in；
The third situation: referring to the first situation and second situation, the upper raising speed of first surface temperature is calculated separately out
Rate Δ v1With the climbing speed Δ v of second surface temperature2If Δ v1With Δ v2Any one climbing speed is greater than first upper limit
Value, then scorch all-in-one machine and be in exsiccosis.
Step S203, judges whether corresponding temperature rate-of-rise is greater than the first upper limit value；If corresponding temperature rises
Rate is greater than the first upper limit value, thens follow the steps S204；If corresponding temperature rate-of-rise is not more than the first upper limit value, hold
Row step S205；
Step S204, intelligent appliance are in exsiccosis；
Step S205, intelligent appliance are in water abundance state.

Step S401 starts to work when steaming mode, and heating tube is heated, and heating tube is closed, and is further continued for opening heating tube
When, in the first surface temperature and second surface temperature of third preset time periodically detection steam generator；
Step S402 calculates temperature difference according to first surface temperature and second surface temperature；
Here, third preset time t can be the second, such as in the case where 2 seconds, and detection first surface temperature is Tin, the
Two surface temperatures are Tout, and Tout-Tin is temperature difference Δ T, scorch whether all-in-one machine is in water shortage according to temperature difference Δ T determination
State.
Step S403, judges whether temperature difference is greater than the second upper limit value；If temperature difference is greater than the second upper limit value, execute
Step S404；If temperature difference is less than second upper limit value, S405 is thened follow the steps；
