Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
One of embodiment of the present invention temprature control method is applied and is needing to carry out in temperature controlled device.It is described

For heating element for heating to target object, temperature sensor is used to obtain the temperature of target object, so that device can be to
The temperature of user's displaying target object, and control effectively to the temperature of target object.
Specifically, described device is used to the temperature of target object being adjusted to preset target temperature by any temperature,
And the temperature of target object is maintained to the target temperature of setting in set period of time hereafter.By taking electric oven as an example, user
The target temperature and heating duration of settable electric oven heating, after user puts food into electric oven, start electric oven to food

System.
The embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.
Fig. 1 is flow diagram corresponding to a kind of temprature control method provided in an embodiment of the present invention, and this method can be by
It is above-mentioned to need to carry out temperature controlled device to execute.As shown in Figure 1, including the following steps 101 to step 103:
Step 101: obtaining the temperature value of the target object measured N heating cycle, N is positive integer；
Step 102: if it is determined that the temperature value of the target object is more than or equal to the first preset temperature, then according to the target
The temperature value of object, the temperature rate-of-rise of pre-set target temperature and the target object or temperature fall off rate, determine institute
State the heating duration of N heating cycle；The heating duration is less than the duration of the N heating cycle；
Step 103: the target object being heated according to the heating duration in the N heating cycle.
Since the heating duration in N heating cycle is the temperature value, pre-set target temperature and temperature according to target object
What degree climbing speed or temperature fall off rate determined, the temperature value of target object is different in the different heating period, it is also possible to cause
The heating duration of target object is different in each heating cycle, therefore, according to the temperature of target object, pre-set target temperature and
Temperature rate-of-rise or temperature fall off rate can targetedly the heating duration to target object in each heating cycle carry out
Adjustment makes the temperature of target object closer to pre-set target temperature to realize after N heating cycle, and by object
The temperature of body remains at the purpose of a small range near target temperature, to effectively reduce temperature fluctuation, improves temperature
The accuracy of control.
In the embodiment of the present invention, described device carries out temperature control to target object through the above steps 101 to step 103
Before system, the temperature of target object need to be adjusted near target temperature.Under normal conditions, the target temperature of setting is generally greater than
Multiple heating mode can be used by the temperature of target object by current temperature value in the current temperature value of target object, described device
It is increased to pre-set target temperature.Wherein, heating method can be by those skilled in the art's self-setting according to actual needs, for not
For the temperature control equipment of same type, the heating method can be identical, can not also be identical, herein with no restrictions.
By taking electric oven as an example, the temperature of food to be heated be can be less than or equal to environment temperature (such as frozen food
Temperature be lower than environment temperature), and the pre-set target temperature set in electric oven is generally much higher than the temperature of environment temperature and food
Degree, then, electric oven can be used heating with full power mode that the temperature of food is quickly risen to pre-set target temperature.
In turn, device can obtain the temperature of target object by the second preset temperature T2Rise to pre-set target temperature TTarget's
Time Δ tup, and calculate temperature rate-of-rise.Specifically, temperature rate-of-rise is equal to (TTarget-T2)/Δtup.Wherein, second is pre-
If temperature may be less than a certain temperature value of pre-set target temperature, specific size can be by those skilled in the art according to practical need
It sets, in the embodiment of the present invention, in order to improve temperature controlled precision, the second preset temperature can be set smaller than default mesh
A certain temperature value within the scope of 5 degree to 10 degree of temperature of mark.
When the temperature of target object is after reaching target temperature, device stops heating target object, however due to heat
The reasons such as the delay hysteresis characteristic of inertia and temperature sensor, the temperature of target object also will continue to increase a period of time.When
After temperature is increased to maximum temperature, since there is a degree of heat exchange, the temperature of target object for device and external environment
It is gradually reduced.
Then, during temperature is gradually reduced, device can obtain the temperature of target object by third preset temperature T3
Drop to the 4th preset temperature T4Required time tdown, and calculate temperature fall off rate.Specifically, temperature fall off rate is equal to
(T3-T4)/tdown。
Wherein, third preset temperature be the target object that arrives of temperature sensor actual measurement in device it is achieved most
High-temperature, size can because the difference of factors such as pre-set target temperature, the leakproofness of device, environment temperature locating for device and
It is different.
Since the maximum temperature that target object reaches generally is spent than pre-set target temperature height about 5 to 10, thus, the 4th
Preset temperature can be set to be more than or equal to pre-set target temperature, and be less than or equal within the scope of 5 degree to 10 degree of third preset temperature
A certain temperature value.In the embodiment of the present invention, the temperature difference between third preset temperature and the 4th preset temperature be can be set to
Temperature difference between pre-set target temperature and the second preset temperature is identical, can not also be identical, herein with no restrictions.
With the temperature difference and third preset temperature and the 4th default temperature between pre-set target temperature and the second preset temperature
Temperature difference between degree is for 5 degree, it can be seen that temperature rate-of-rise and temperature fall off rate are reflected in goal-selling
The rate temperature change within the scope of temperature near temperature, that is, temperature rate-of-rise is actually that the temperature of target object rises
Last 5 degree of rate temperature change during to pre-set target temperature, and temperature fall off rate is to be gradually reduced by maximum temperature
To last 5 degree of rate temperature change during target temperature.
In the embodiment of the present invention, the temperature of target object is adjusted near pre-set target temperature in described device, and counts
After calculation obtains temperature fall off rate, above-mentioned steps 101 can be performed to step 103.
Specifically, in step 101, the temperature for the target object that N is measured heating cycle can be N heating cycle
When beginning, the temperature for the target object that temperature sensor measurement arrives.Wherein, N is the integer more than or equal to 1.
By taking the N heating cycle in temperature controlled processes as an example, in step 102, described device gets N heating cycle
After the temperature value of middle target object, first determine whether the temperature value of target object is more than or equal to the first preset temperature, if greatly
In equal to the first preset temperature, it is determined that the temperature of current goal object is closer to pre-set target temperature, in turn, can basis
The temperature value of the target object, the temperature rate-of-rise of pre-set target temperature and the target object or at a temperature of reduction of speed
Rate determines the heating duration of the N heating cycle.
It is on the contrary, however, it is determined that the temperature of current goal object is less than the first preset temperature, it may be determined that the temperature of current goal object
Degree with pre-set target temperature differs larger, then, the heating duration of N heating cycle can be determined as N heating cycle when
It is long, so that the temperature of target object is increased near target temperature as early as possible.
For example, user uses electric oven baked food, and after electric oven has been raised to the target temperature of setting, electricity is roasting
Case can be in the heating in the certain period of time of the duration of any heating cycle, and remaining time does not heat.Since user may be
Open the door of electric oven during food baking, such as smear sauce for food, check food baking state etc., such case
Under, the temperature in electric oven will reduce rapidly.User closes baking machine behind the door, in order to make the temperature in electric oven fast as early as possible
To the target temperature of setting, electric oven can heat always quick-recovery in entire heating cycle.
Wherein, the first preset temperature is less than pre-set target temperature, and the size of the first preset temperature can be by art technology
Personnel's sets itself according to actual needs.By taking electric oven as an example, preset first temperature can be set to comparing pre-set target temperature
Small 10 degree of temperature, if 10 degree lower than pre-set target temperature of temperature or less in electric oven, it may be determined that the temperature of target object
Differ larger with pre-set target temperature, therefore, the mode that heating with full power can be used heats, and increases the temperature of electric oven as early as possible
To pre-set target temperature, to reach, so that the temperature in electric oven is remained at pre-set target temperature in setting heating duration attached
Close purpose.
After determining the heating duration of N heating cycle, described device can be according to determining heating duration to target object
It is heated.Target object is added if duration of the heating duration less than N heating cycle, in described device is long when heated
After the completion of heat, stop heating.
After the temperature value for determining target object to described device is more than or equal to the first preset temperature below, according to object
The temperature value of body, the temperature rate-of-rise of pre-set target temperature and the target object or temperature fall off rate, determine described in
The process of the heating duration of N heating cycle is described in detail.
If it is determined that the temperature value of target object is more than or equal to the first preset temperature, it is less than pre-set target temperature, the dress
Setting can be according to the temperature rate-of-rise of the temperature value of target object, pre-set target temperature and target object, using following formula
Determine the heating duration of N heating cycle:
Wherein, tHeatingFor the heating duration of the N heating cycle, tPeriodFor the duration of the N heating cycle, tupFor institute
State target object temperature pre-set target temperature is risen to as the second preset temperature needed for the time, tdownFor the target object
Temperature the 4th preset temperature is dropped to as third preset temperature needed for the time, T be the target object temperature value, TTarget
For the pre-set target temperature, vupFor the temperature rate-of-rise, K is temperature compensation coefficient.
As can be seen that can choose when the temperature of target object is within the scope of the temperature near pre-set target temperature
Target object is heated in the partial time period of a certain heating cycle, and other time does not heat, so that the temperature of target object
Degree maintains near pre-set target temperature.Then, N heating week can be determined according to the temperature change near pre-set target temperature
The heating duty ratio of phase, that is, the ratio of interior heating duration and duration N heating cycle N heating cycle.
Specifically, can the temperature of target object by the second preset temperature rise to pre-set target temperature rise to it is default
Time t needed for target temperatureup, account for the second preset temperature and rise to pre-set target temperature tupDrop to third preset temperature
T the time required to 4th preset temperaturedownThe sum of ratioInitial heating duty ratio as N heating cycle.
Further, when the temperature value of target object is less than pre-set target temperature, in order to quickly make target object
Temperature value is increased to pre-set target temperature, suitably can increase by one in the molecule of the initial heating duty ratio of N heating cycle
A heating duty is than offset K (TTarget-T)/vup, to increase the heating duration in N heating cycle.
Due to heating duty than offset be according to the gap of target object current temperature value and pre-set target temperature, with
And the temperature rate-of-rise rate near goal-selling of target object jointly determine, so, the temperature of target object with
Pre-set target temperature difference is bigger, and heating compensation value is also bigger, and heating duration is also correspondingly bigger in N heating cycle, will
The temperature of target object adjusts faster to pre-set target temperature.
As the gap between the temperature and pre-set target temperature of target object is gradually reduced, heating compensation value also gradually becomes
Small, the heating duration in N heating cycle is gradually shortened, and this improves the accuracy in temperature controlled processes, reduce mesh
Mark fluctuation of the temperature of object near pre-set target temperature.
It should be noted that temperature compensation coefficient K is the real number greater than 0.Since K value is bigger, heating duty compares offset
Bigger, the temperature adjusting of target object is faster to pre-set target temperature, and correspondingly, the temperature fluctuation of target object becomes
Greatly, temperature control precision reduces, thus, those skilled in the art can according to actual needs and type of device self-setting temperature
Spend the size of penalty coefficient.
In the embodiment of the present invention, any value that temperature compensation coefficient K can be set as in [0.7,1.3] range.When
So, in order to obtain better temperature control effect, those skilled in the art can also be in temperature controlled processes, to temperature-compensating
Coefficient suitably adjusts, herein with no restrictions.
, whereas if determining that the temperature value of target object is greater than pre-set target temperature, described device can be according to target object
Temperature value, pre-set target temperature and target object temperature fall off rate, N heating cycle is determined using following formula
Heat duration:
Wherein, tHeatingFor the heating duration of the N heating cycle, tPeriodFor the duration of the N heating cycle, tupFor institute
State target object temperature pre-set target temperature is risen to as the second preset temperature needed for the time, tdownFor the target object
Temperature the 4th preset temperature is dropped to as third preset temperature needed for the time, T be the target object temperature value, TTarget
For the pre-set target temperature, vdownFor the temperature fall off rate, K is temperature compensation coefficient.
Specifically, when the temperature value of target object is greater than pre-set target temperature, in order to quickly make target object
Temperature value is reduced to pre-set target temperature, suitably can increase by one in the denominator of the initial heating duty ratio of N heating cycle
A heating duty is than offset K (T-TTarget)/vdown, to reduce the heating duration in N heating cycle.
Likewise, since heating duty than offset is the temperature value and pre-set target temperature current according to target object
What gap and the temperature rate-of-rise rate near goal-selling of target object determined jointly, so, target object
Temperature differs bigger with pre-set target temperature, and heating compensation value is also bigger, and denominator is bigger in heating duty ratio, N heating
It heats duration in period also correspondingly to become smaller, it is faster that the temperature of target object is reduced to pre-set target temperature.
As the gap between the temperature and pre-set target temperature of target object is gradually reduced, heating compensation value also gradually becomes
Small, the heating duration in N heating cycle becomes larger, and therefore, can effectively improve the accuracy in temperature controlled processes,
Reduce fluctuation of the temperature of target object near pre-set target temperature.
