The unloaded electricity consumption value of storage and the power consumption for cooking object before in one or more memories corresponding to individual power device
Value；Wherein, processor according to stored in one or more memories it is cumulative after unloaded electricity consumption value and for cooking object
Electricity consumption value calculates efficiency level.
" unloaded electricity consumption value " refers to not placing the electricity consumption value in the case of any cooking food in cooking apparatus；It is " real
Border electricity consumption value " refers to placed the electricity consumption value in the case of cooking food in cooking apparatus；" it is used for the power consumption for cooking object
Value " refers to the electricity consumption value for cooking the food being placed in cooking apparatus.Here " unloaded electricity consumption value ", " actual power consumption
Value ", the electricity consumption value of object " be used for cook " be the power consumption for a power device being directed in one or more power devices and
Speech." the unloaded power consumption " and " culinary art object power consumption " being described below is directed in one or more power devices
All power devices for.
One cooking apparatus potentially includes one or more power devices, for example, micro-wave oven potentially includes heat-generating pipe, steam
Generator, power fan motor etc., these power devices need to consume electric energy.Herein, it is each power device
Part is correspondingly arranged a memory, thus, one or more power devices are accomplished by being correspondingly arranged one or more memories.
Unit interval typically can be 1 second, but can be changed according to the size of the memory used, for example, can
Think 10 seconds, 1 minute etc., as a rule, memory is smaller, and the unit interval can be longer, the present invention was said exemplified by 1 second
It is bright.
Above technical scheme is described further with reference to Fig. 2, Fig. 2 is the calculating cooking apparatus that the present invention is provided
Energy consumption level method flow diagram, in fig. 2：
Step 201, cooking apparatus is started working.Generally cooking apparatus is started by user, and is set according to user
Time or setting temperature work, be stopped in the case where reaching set time or set temperature.
Step 202, timer starts timing, and timer here is based on carrying out timing to (1 second) unit interval
When device, in the case where timer timing time reaches the unit interval, continue to proceed by the timing of next unit interval,
Exactly circulate and timing is carried out to the unit interval.
Step 203, judge whether timing time reaches the unit interval, in case of arrival perform step 204, otherwise after
Continuous timing.Step 204 is performed namely in the case where timing time often reaches the unit interval.
Step 204, unloaded electricity consumption value, the actual power consumption value of one or more power devices in the nearest unit interval are calculated
And the difference between unloaded electricity consumption value and actual power consumption value.Here when the nearest unit interval refers to the unit just terminated

Difference between load electricity consumption value, actual power consumption value and unloaded electricity consumption value and actual power consumption value is added up.Do not have in step 205
Actual power consumption value is carried out it is cumulative be because being calculating efficiency level in the technical scheme purpose to be reached that the present invention is provided,
And the parameter needed for the calculating of efficiency level is the unloaded electricity consumption value and the cumulative electricity consumption value for being used to cook object added up, so
Here it have ignored the storage to actual power consumption value and cumulative.Also, power device one memory of correspondence, so one is deposited
The data of reservoir correspondence one power device of storage, including unloaded electricity consumption value, actual power consumption value and unloaded electricity consumption value consume with actual
Difference between electricity value.
Step 206, judge whether to receive query statement, step 208 is performed in the case where receiving query statement, it is no
Then perform step 207, the query statement for example can be in user it should be understood that being sent out by user terminal during current efficiency level
Send.
Step 207, judge whether cooking apparatus is stopped, step 208 is performed in the case where being stopped, is otherwise returned
Continue to carry out timing to the unit interval to step 202.
Step 208, according to stored in one or more memories it is cumulative after unloaded electricity consumption value and for cooking object
Electricity consumption value calculate efficiency level.As shown in Fig. 2 the step 208 can judge that cooking apparatus is stopped in step 207
Carry out, can also judge in step 206 in the case of receiving query statement in the case of (that is, cooking apparatus end of run)
Carry out.It can be shown for the efficiency level that calculating is obtained by the display panel of cooking apparatus, can also send whole to user
Hold to inform user.
It will be appreciated by those skilled in the art that can be set for the opportunity for calculating efficiency level according to actual conditions,
For example, query statement only can received (by user terminal in the case of wanting to know about current efficiency level in user
Send the query statement) in the case of calculate, can also only calculate, certainly, also may be used in the case where cooking apparatus is stopped
To receive query statement and cooking apparatus is stopped in the case of two kinds and calculated.
In Fig. 2 step 208 according to stored in one or more memories it is cumulative after unloaded electricity consumption value and be used for
The electricity consumption value of culinary art object comprises the following steps that to calculate efficiency level：To stored in one or more memories it is cumulative after
Unloaded electricity consumption value summation obtains the unloaded power consumption of cooking apparatus；To stored in one or more memories it is cumulative after be used for
The electricity consumption value summation of culinary art object obtains cooking object power consumption；Asking for cooking the ratio of object power consumption and unloaded power consumption is worth
To efficiency level.
It should be understood that to stored in one or more memories it is cumulative after the summation of unloaded electricity consumption value cooked
The unloaded power consumption of utensil refer to storing in all memories to one or more memories it is cumulative after unloaded power consumption
Value summation, i.e., the unloaded electricity consumption value sum that all power devices are consumed, to stored in one or more memories it is cumulative after
Be used for cook object electricity consumption value summation obtain culinary art object power consumption refer to depositing all of one or more memories
Stored in reservoir it is cumulative after the electricity consumption value summation for being used to cook object obtain cooking object power consumption, i.e., all power devices
The electricity consumption value sum for being used to cook object consumed.Certainly, in practical operation, main work(that can also only to cooking apparatus
The unloaded electricity consumption value and actual power consumption value that rate device is consumed are calculated and subsequent treatment.
Here, the unit of unloaded electricity consumption value can be selected as 0.1 kilowatt hour, because in a practical situation, power device is (such as
Heating element, steam generator etc.) power all there is certain deviation (such as -8%~+2%) mostly, if unit sets too
Small, then due to the presence of this deviation, several bit digitals behind shown result are actually to be difficult to what is tallied with the actual situation,
So unit Ding get Tai is small without much meanings, and if unit is fixed greatly, such as 1 degree (kilowatt hour), for culinary products this
Kind generally open half to one hour less than equipment, shown result again can be too coarse, so, using 0.1 kilowatt hour work
For the household appliances object (usual rated power is more than hundreds of to two thousand watts) designed by the present invention it is to compare for unit
Suitably.
Certainly, those skilled in the art can also according to actual conditions and actual demand come the appropriate unit of sets itself,
In the case that in the unit interval, selection is 1 second, the unit of the unloaded electricity consumption value of power device can be 100 watt-seconds, then cook
Prepare food utensil unloaded power consumption calculation formula it is as follows：
In the case that in the unit interval, selection is 1 second, the unit for being used to cook the electricity consumption value of object of power device can be with
For 10 watt-seconds, then the calculation formula of the unloaded power consumption of cooking apparatus is as follows：
0.01 kilowatt hour and 10 watt-seconds are why selected as unit, are because being calculated by above method
Power be all often tens to arrive several hectowatts, if selection unit is too big, is easily caused result of calculation and deviates with actual
It is too big, such as cross unit and select too small, then because power device (for example, heating element) generally has error, too small unit is used for
Computing is also meaningless.
On the basis of above formula (1) and formula (2), the calculation formula of efficiency level is as follows：
The equipment of the efficiency level for the calculating cooking apparatus that the present invention is provided also includes temperature setting device, temperature setting
Device is used for sets target heating-up temperature, and processor obtains one or more within the current one time according to target heating temperature
The unloaded make-to-break ratio of power device, and corresponding one or many was obtained within the current one time according to unloaded make-to-break ratio calculating
The unloaded electricity consumption value of individual power device.
" make-to-break ratio of power device " refers to the ratio of power device turn-on time and turn-off time, " power device
Unloaded make-to-break ratio " refer to not placing any cooking food in cooking apparatus in the case of power device make-to-break ratio, under
Power device in the case that " the actual make-to-break ratio of power device " refers to placed cooking food in cooking apparatus in text
Make-to-break ratio.
Because the power of power device is fixed, thus electricity consumption value of the power device within the unit interval is namely fixed
, in the case where knowing the unloaded make-to-break ratio in the unit interval, and the unit interval internal strength can be easily calculated
The electricity consumption value of rate device.
Processor obtains the unloaded make-to-break ratio of one or more power devices within the current one time according to design temperature
Including：The unloaded cavity temperature obtained in the current one time is calculated according to target heating temperature；According in the current one time
Unloaded cavity temperature obtain the unloaded make-to-break ratios of one or more power devices corresponding with the unloaded cavity temperature；Its is hollow
The corresponding relation carried between cavity temperature and the unloaded make-to-break ratio of one or more power devices is previously stored.
For a power device, corresponding relation between unloaded cavity temperature and unloaded make-to-break ratio is one a pair
Answer, the corresponding relation can be previously stored, it is possible to pass through unloaded cavity temperature and the unloaded make-to-break ratio prestored
Between corresponding relation unloaded make-to-break ratio obtained according to unloaded cavity temperature.However, due in cooking process, cooking apparatus
In placed cooking food, so unloaded cavity temperature needs reckoning to obtain, can be heated by below equation according to target
Temperature computation obtains the unloaded cavity temperature in the current one time：
T=k1×k2×t+(1-k1)×T0 (4)
In formula (4), T is unloaded cavity temperature, T0For target heating temperature, k1For stage coefficient, k2For temperature-time system
Number, t is the run time of cooking apparatus；In the ascent stage of unloaded cavity temperature, k1For 1, mesh is reached in unloaded cavity temperature
In the case of marking heating-up temperature, k1For 0, k2For constant.Wherein, k2Can be that a fixed value or one increase with the time
Plus and constantly reduction value to cause operation result to more conform to actual conditions, for k2Specific value, people in the art
Member can determine according to actual conditions.
So that power device is heating element as an example, it is assumed that cooking apparatus is run in the case where being loaded with food, cavity temperature
Degree constantly rises, when operation was to the 180th second, according to formula (4), if situation its unloaded cavity temperature for calculating zero load is
150 DEG C, correspondingly, processor is obtained in this temperature spot (150 according to unloaded cavity temperature and the corresponding relation of unloaded make-to-break ratio
DEG C) under the unloaded break-make situation of heating element (if it is 1200 watts heat-generating pipe) led to for 16 seconds, 8 seconds disconnected, and (make-to-break ratio is 2:1),
The electricity consumption value being then converted under the unit interval (unit interval is 1 second) come is 800 watt-seconds.
The computational methods to the actual power consumption value of a unit interval are described below, and the invention provides two kinds of calculating
Method.
In the method for the actual power consumption value of the first one unit interval of calculating, the calculating cooking apparatus that the present invention is provided
Efficiency level equipment also include temperature-detecting device, the temperature-detecting device be used for circulation each unit interval pair
Temperature in the cavity of cooking apparatus is detected；Processor obtains working as according to the temperature in the current one time detected
The actual make-to-break ratio of one or more power devices in the preceding unit interval, and obtained according to actual make-to-break ratio calculating current single
The actual power consumption value of corresponding one or more power devices in the time of position；Wherein, the temperature in the current one time detected
Corresponding relation between degree and the actual make-to-break ratio of one or more power devices is previously stored.
" target heating temperature " is the cooking apparatus temperature finally to be reached, however, due to being arranged in cooking apparatus
Temperature-detecting device position it is different, detected temperature is also just different, thus can be to set in practical operation
Target heating temperature adjusted accordingly according to the position difference of temperature-detecting device, however, this is just for the sake of more
Accurately realize technical scheme." target heating temperature " in the present invention can be set value, or
Value after adjustment.
It should be noted that the unloaded break-make of the unloaded cavity temperature being described above and one or more power devices
Temperature and the actual break-make of one or more power devices in corresponding relation than between and the current one time detected
Corresponding relation than between can be to be stored or same corresponding relation, because unloaded cavity temperature and being examined
Temperature in the current one time of survey is all temperature value, and unloaded make-to-break ratio and actual make-to-break ratio are all make-to-break ratios, thus, they
Corresponding relation be essentially all the corresponding relation reflected between temperature and make-to-break ratio, thus show in being stored at one.
Fig. 3 is the temperature variation curve in the cooking apparatus that the present invention is provided, in figure 3, and abscissa t is the time, indulges and sits
Mark T is temperature, and curve 301 is does not place the temperature variation curve of cooking food in cooking apparatus, curve 302 is in cooking apparatus
It placed the temperature variation curve of cooking food.In the case of being placed with cooking food in cooking apparatus, when equal
Between the temperature that is detected of temperature-detecting device in point (the 180th second) cavity than it is unloaded when it is low, therefore obtain corresponding reality and lead to
The disconnected unloaded make-to-break ratio frequently with equi-time point will be grown, so that when the electricity consumption value spent by the power device being converted into is than zero load
It is high.Now, the electricity consumption value that we will be now converted into when next electricity consumption value subtracts correspondence time point zero load, just can obtain this unit
The electricity consumption value in food load is consumed under time.
For above mentioned example, if the temperature that now (the 180th second) temperature-detecting device is detected is 140
DEG C, processor is according between the temperature and the actual make-to-break ratio of one or more power devices in the current one time detected
Corresponding relation obtain the corresponding actual break-make situation of the temperature spot and led to for 18 seconds, 6 seconds disconnected, and (make-to-break ratio is 3:1), then it is converted into
Electricity consumption value under the unit interval (unit interval is 1 second) come is 900 watt-seconds.So that is, in this of the 180th second
In one second, the electricity consumption value for cooking object is 100 watt-seconds (watt-second of 900 watt-second -800).
In the method for the actual power consumption value of second of one unit interval of calculating, processor calculates the nearest unit interval
The actual power consumption value of interior one or more power devices includes：By in one or more power devices for one of on-state or
The actual power consumption value of multiple power devices is set as a fixed value；To be the one of its unaccessed state in one or more power devices
The actual power consumption value of individual or multiple power devices is set as zero.
Within each unit interval (for example, 1 second), the processor progress detection that whether is powered to each power device is sentenced
Disconnected, for a power device, if the power device is is powered and (run), the power device is within the unit interval
Actual power consumption value be fixed value (in example mentioned above be 1200 watt-seconds), if the power device for power-off (i.e.
Do not run), actual power consumption value of the power device within the unit interval is zero (0 watt-second).Those skilled in the art should
Understand, the power can be judged by the control signal for the switching device (such as relay, triode) for controlling power device
Device is switched on also being powered off.
It will be appreciated by those skilled in the art that in the case where calculating actual power consumption value using second method, should note
Meaning subtracts unloaded electricity consumption value with actual power consumption value to obtain the electricity consumption value for cooking object, it is readily appreciated that, in a unit
If interior actual power consumption value is zero, the electricity consumption value for being used to cook object in the unit interval is negative value.
We can obtain the calculation formula Q=Cm △ T of heat according to material to understand the thinking of the present invention：In unloaded feelings
Under condition, because cooking apparatus and environment are kept substantially and stablize constant, so, under normal no-load operation, the chamber of cooking apparatus
Temperature lifting will necessarily be run along similar temperature rise curve.After cooking food is placed into culinary art cavity, food is in quilt
A part of heat can be consumed in heating process, is caused in whole cooking process, the temperature in the cavity of cooking apparatus is placed on
The temperature that is detected of degree detection means than it is unloaded when it is low.Now, because the temperature signal of feedback is low, so processor can increase
Plus the make-to-break ratio of the major power device such as heating element, to attempt culinary art cavity temperature being returned to and identical mesh under no-load condition
Mark temperature.Certainly, in the case where there is this control mode of loading condition, when the temperature of culinary art cavity can unlikely be returned to zero load
Temperature because like this, as when the make-to-break ratio of heating element will be such as zero load, it is clear that extra food can not be supported to add
Heat, cavity temperature will necessarily drop once again, unless no longer absorbed heat (in theory, only in food in itself as the food of extra load
Thing carbonization is possible to such case occur, and actual conditions are, the detection error in sensor in itself, by foot
Enough under long run time, the end of load temperature rise curve (curve 302 in Fig. 3) is possible to unloaded temperature rise curve (in Fig. 3
Curve 301) end overlap).
Ten thousand) or even can memory above be all at least that (16bit may store the maximum of numerical value for 6.5 to double byte
To be that (hundred million) 32bit may store the maximum of numerical value for 43, recorded to provide enough capacity ensuing nybble
Power consumption accumulated value.
Correspondingly, present invention also offers a kind of horizontal caution system of efficiency, the system includes：The calculating that the present invention is provided
The equipment of the efficiency level of cooking apparatus；Display device, for showing calculated efficiency level；And warning device, in institute
The efficiency level of calculating not within the predefined range in the case of, alarmed.The mode that warning device is alarmed can be sound
Light alarm or by display device display alarm information, can also be alarmed by user terminal, i.e., whole to user
End sends warning message.
When efficiency level is less than zone of reasonableness (if less than 35%), then warning device is to being alarmed, if efficiency water
When flat at a fairly low or at a relatively high (if less than 30% or more than 60%), then processor can directly terminate the fortune of cooking apparatus
OK, and point out to look for after-sale service to carry out related detection and maintenance.Why so set, be because when energy consumption is at a fairly low,
It is probably that input voltage is too low or heating element (one of power device) performance itself has deviated from normal level, reruns down
Go, irreversible damage may be caused to occur, or even can crisis user life or property safety；If efficiency level is too high,
Be likely to heating element shorted to earth, it is serious in the case of (such as no ground line in user family), the then metal watch of product
Face may be powered, it may occur that Danger Electric shock risk.
