Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
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.
Be affected currently, being painted due to food baking by direct heat radiation, and in an oven accommodating food when, often
Secondary placement location also will appear biggish difference, not ensure that when being accurately placed on design on preset location point, because
The constant temperature in this place for causing food to be roasted close from heating member is higher, and the constant temperature in the place remote from heating member
It is relatively low, it also allows for food colouring to be roasted and huge difference occurs.It is provided in an embodiment of the present invention a kind of roasting based on this
Case and its method for heating and controlling adjust heating power by difference of the heating device at a distance from baking food, can make to reach
The heat of baking food is more uniform, so that foodstuff surface colouring consistency is high, color difference is small.
To be carried out first to a kind of oven disclosed in the embodiment of the present invention detailed convenient for understanding the present embodiment
It introduces.
As shown in Figure 1-Figure 3, a kind of oven provided in an embodiment of the present invention, including shell 1 and setting are in shell 1
Liner 3, control panel 2 is provided between shell 1 and liner 3, top, bottom, left part and the right part of liner 3 are respectively arranged with
Upper heating device 4, lower heating device 7, left heating device 5 and the right heating device 6 being connect with control panel 2；Wherein, upper heating
Device 4 includes the upper inner heating device 41 and upper external heating device 42 to work independently of one another；The top of wall of inner container, bottom, left part
The upper range unit 91 connecting with control panel 2, lower range unit 94, left range unit 92 and right survey are respectively arranged with right part
Away from device 93；
Upper heating device 4, lower heating device 7, left heating device 5 and right heating device 6 respectively heat liner 3,
To carry out heated baking to baking food；The range unit of all directions is used to measure all directions of the wall of inner container and baking is eaten
The distance between object, i.e., upper range unit 91, lower range unit 94, left range unit 92 and right range unit 93 measure respectively
The top of wall of inner container, bottom, left part and the distance between right part and baking food；Specifically, range unit is fixed on wall of inner container
Inside.
Control panel 2 is used to adjust the heating power of corresponding heating device according to the distance of all directions, i.e., according to wall of inner container
Top, bottom, left part and the distance between right part and baking food adjust upper heating device 4, lower heating device 7, Zuo Jiare
The heating power of device 5 and right heating device 6.Specifically, heating power is adjusted by adjusting the duty ratio of heating device.
In practical work process, heating device eats baking food heated baking, range unit to wall of inner container and baking
The distance of object measures, and by measurement feedback to control panel 2, control panel 2 adds according to the adjustment of the distance of all directions is corresponding
The heating power of thermal, specific adjustment mode are as follows: the heating power apart from big direction is big, the heating apart from small direction
Power is small, adjusts small with the ratio of distance difference (unit is millimeter) to the power difference in any two direction (unit is watt)
In can be 3 equal to the first setting value, such as the first setting value, it can also be other values.
After above-mentioned adjusting, the heating of the remote heating device of high power and low-power short distance can be made to fill
It sets and is transmitted to the thermal energy of foodstuff surface and more tends to unanimously, keep food heated more evenly, and during being baked colouring, food
Surface coloring consistence effect is more obvious.
In order to keep baking food heated more evenly, 3 rear portion of liner is provided with the heated air circulation device 8 heated to liner 3,
Wherein thermocirculator 8 includes having the back plate 81 of inlet and outlet and the post-heater 82 that is heated to circulated air and following
Ring blower, back plate 81 it is removable be fixed on 3 rear portion of liner.
Further, the top, bottom of liner 3, left part and right part are respectively arranged with the upper temperature connecting with control panel 2
Sensor 31, lower temperature sensor 34, left temperature sensor 32 and right temperature sensor 33；

Temperature, bottom wall temperature, left part wall surface temperature and right part wall surface temperature；
Control panel adjusts the heating power of corresponding heating device according to the wall surface temperature of all directions.
Specifically, after adjusting power according to the distance of all directions, the temperature sensor real-time monitoring of 3 all directions of liner is each
The wall surface temperature in direction, control panel 2 further adjust the heating power of each heating device according to the wall surface temperature of all directions.With
On the basis of the power bracket of setting (i.e. between lowest power and peak power), heating power is adjusted, so that any two side
To temperature gap (unit be DEG C) and the ratio of distance difference (unit is millimeter) be less than or equal to the second setting value, such as the
Two setting values can be 0.2, can also be other values.
When the ratio of the temperature gap in two of them direction and distance difference is greater than the second setting value, illustrate the two
There is big deviation in the temperature of the foodstuff surface in direction, and being heated evenly property is weaker, at this time, it may be necessary to adjust adding for the two directions
Thermal power.The heating power apart from remote heating device can first be increased, after by maximum is transferred to apart from remote heating power,
Desired effect has not been reached yet, then reduces the heating power of the heating device apart from close direction；Furthermore it is also possible to first reduce
Heating power apart from close heating device, after by minimum is transferred to apart from the heating power of close heating device, there are no reach
To in expected situation, then increase the heating power apart from remote heating device.
Carry out dynamic regulation according to above-mentioned adjustment process, even if position and position when design that food is placed occur compared with
When large deviation, the radiation temperature difference that can also make all directions reach foodstuff surface be can control within smaller value, such as 1
DEG C or so.In baking food, foodstuff surface color consistency is good, and foodstuff surface colouring uniformly, facilitates user more easily to make
With.
Further, it is provided with glass-ceramic 10 between 3 cavity of upper heating device 4 and liner, upper range unit 91 and upper
Temperature sensor 31 is arranged on glass-ceramic 10.Here, second radiation after upper heating device 4 is heated by glass-ceramic 10
Can, so that more uniform temperature.
As an optional implementation manner, left range unit 92, right range unit 93 are separately positioned on 3 height of liner
1/3 to 2/3 height at；Upper range unit 91, lower range unit 94 are separately positioned on 1/3 from left to right of 3 width of liner
To at 2/3 position；Preferably, left range unit 92, right range unit 93 are separately positioned on the center position of 3 height of liner；
Upper range unit 91, lower range unit 94 are separately positioned on the center position of 3 width of liner.
