Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
An oven temperature control method, an oven temperature control apparatus, and an oven according to embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an oven temperature control method according to an embodiment of the present invention.
It should be noted that the oven in this embodiment has functions of microwave, barbecue, and hot air.
As shown in fig. 1, the oven temperature control method may include the steps of:
s1, detecting a current temperature at the first position by the first temperature sensor.
Referring to fig. 4, the first temperature sensor described in this embodiment may be an NTC (negative temperature Coefficient) temperature sensor, and the first position may be a corner position (oven angle) of the oven cavity top cover.
And S2, according to the current temperature, inquiring the mapping relation between the temperature at the first position and the temperature at the second position to obtain the reference temperature at the second position.
Referring to fig. 4, the second position described in this embodiment may be a center position (core) of the base of the oven case. Specifically, the mapping relationship between the temperature at the first position and the temperature at the second position may be established in advance through experiments and stored in the oven.
And S3, detecting the actual temperature at the second position by the second temperature sensor.
Referring to fig. 4, the second temperature sensor in this embodiment may be a thermocouple, which has high temperature measurement accuracy, a large measurement range, and can endure high temperature, so that the oven can be applied when it operates with different fire types (such as microwave, barbecue, hot air, etc.).
And S4, performing temperature control adjustment on the second position according to the reference temperature and the actual temperature.
According to one embodiment of the present invention, the temperature-controlled adjustment of the second position according to the reference temperature and the actual temperature comprises: acquiring a difference value between the reference temperature and the actual temperature; according to the difference, acquiring the on-off time ratio of the heating element corresponding to the second position; and controlling the on-off of the heating element according to the on-off time ratio so as to adjust the actual temperature at the second position.
Specifically, a first temperature sensor (such as an NTC temperature sensor) detects a current temperature at a first location (a furnace corner) in real time, and a reference temperature at a second location corresponding to the current temperature at the first location is obtained by querying a mapping relationship between the temperature at the first location and the temperature at the second location. At the same time, the actual temperature at the second location (e.g., the core) is detected in real time by a second temperature sensor (e.g., a thermocouple). After the reference temperature and the actual temperature at the second position are obtained, the difference between the reference temperature and the actual temperature is calculated, the on-off time ratio (duty ratio) of the heating element corresponding to the second position is obtained according to the difference, and then the on-off of the heating element is controlled according to the obtained on-off time ratio of the heating element so as to adjust the actual temperature at the second position.
For example, when the difference between the reference temperature and the actual temperature at the second position is greater than a first preset temperature threshold (e.g., 1 ℃), increasing the on-off time ratio of the heating element corresponding to the second position, and controlling the on-off of the heating element according to the increased on-off time ratio to increase the actual temperature at the second position; and when the difference between the reference temperature and the actual temperature at the second position is smaller than a second preset temperature threshold (such as minus 1 ℃), reducing the on-off time of the heating element corresponding to the second position, and controlling the on-off of the heating element according to the reduced on-off time ratio so as to reduce the actual temperature at the second position.
Therefore, the temperature of the second position of the oven can be accurately controlled through the mapping relation between the temperature of the first position and the temperature of the second position, so that delicious food can be cooked.
The following describes how to establish a mapping relationship between the temperature at the first location and the temperature at the second location, in conjunction with a specific embodiment of the present invention.
In an embodiment of the present invention, before detecting the current temperature at the first location by the first temperature sensor, the method further includes: receiving a preset instruction of the oven power, and setting the target power of the oven according to the preset instruction; and acquiring a mapping relation matched with the target power.
In an embodiment of the present invention, before detecting the current temperature at the first location by the first temperature sensor, the method further includes: acquiring a first sample temperature at a first location via a first temperature sensor and simultaneously acquiring a second sample temperature at a second location via a second temperature sensor; and constructing a mapping relation according to the first sample temperature and the second sample temperature.
It should be noted that, in the embodiment, the first position is an oven corner, the second position is an oven core, the first temperature sensor is an NTC temperature sensor, and the second temperature sensor is a thermocouple.
Referring to fig. 2-4, a mapping relationship development system of an embodiment of the present invention may include an oven, a PC, and a thermocouple thermometer. In the system, a computer board of the oven is communicated with LabVIEW software of a PC (personal computer) through a serial port, so that the on-line real-time adjustment of microwave and barbecue tube or hot air output power and the automatic acquisition and recording of the temperature of an NTC (negative temperature coefficient) temperature sensor at the corner of the oven are realized.
The thermocouple temperature measuring instrument in the embodiment is connected with a thermocouple of the oven core through a connecting wire, and is used for measuring the temperature of the oven core in the development process of the mapping relation in real time and realizing online temperature detection. The setting button of the thermocouple thermometer communicates with LabVIEW software of a PC (personal computer) through a USB (Universal Serial Bus) interface.
The functions of the LabVIEW software are shown in fig. 3 and may include table format input, graphical display, real-time on-line control of fire, automatic data storage, sensor acquisition, and the like.
The principle of the mapping relationship development method of the embodiment of the invention is as follows: the user presses a setting button to start a thermocouple thermometer, the thermocouple thermometer detects the temperature of the furnace core in real time through a thermocouple arranged in the oven furnace core, and LabVIEW software collects and records furnace core temperature data (second sample temperature data) collected by the thermocouple of the oven furnace core monitored by the thermocouple thermometer in real time and furnace corner temperature data (first sample temperature data) collected by an NTC temperature sensor of an oven furnace corner. Therefore, automatic acquisition and recording of temperature data of the oven core and the oven corner can be realized, and efficient product development is realized.
The development method of the mapping relation can comprise the following steps:
step 1, setting microwave, a barbecue tube or hot air on the oven to be started through LabVIEW software, and enabling the LabVIEW software to collect and record oven corner temperature Tb at the oven corner collected by an NTC temperature sensor in real time and collect and record oven core temperature Tc at the oven core collected by a thermocouple.
And 2, analyzing the acquired furnace corner temperature Tb and furnace core temperature Tc, and constructing a mapping relation f1 corresponding to the furnace corner temperature Tb and the furnace core temperature Tc.
And 3, continuously changing the starting state of the microwave, the barbecue tube or the hot air, namely controlling the target power of the microwave, the barbecue tube or the hot air to be continuously changed, and repeating the step 1 and the step 2 to obtain different mapping relations fn, namely obtaining the mapping relation matched with the target power.
During actual use, the oven can obtain the reference temperature of the furnace core through conversion by the furnace angle temperature acquired by the NTC sensor at the furnace angle through the constructed mapping relation, so that the temperature control adjustment of the oven furnace core can be accurately realized.
It should be noted that the second position is not limited to the position of the core in the embodiment of the present invention, and may be any position in the oven, so that the temperature in any position in the oven can be precisely controlled.
How to construct the mapping relationship according to the first sample temperature and the second sample temperature is described in detail below with reference to fig. 5a and 5 b.
In one embodiment of the present invention, constructing a mapping relationship based on the first sample temperature and the second sample temperature comprises: performing polynomial fitting on the first sample temperature and the second sample temperature to form a mapping relation; or, the first sample temperature and the second sample temperature are linearly mapped to form a mapping relation.
Specifically, referring to fig. 5a, the first sample temperature (furnace corner temperature Tb) and the second sample temperature (core temperature Tc) are linearly mapped, and the following formula (1) may be obtained:
Tc＝0.9978*Tb+4.8047 (1)
alternatively, referring to fig. 5b, the following formula (2) can be obtained by performing polynomial fitting processing on the first sample temperature (furnace corner temperature Tb) and the second sample temperature (furnace core temperature Tc):
Tc＝0.0009*Tb2+1.1591*Tb+0.2153 (2)
the coefficient R of the formula (1) obtained by linear mapping in fig. 5a is the coefficient R of the coefficient20.9953, the coefficient R of formula (2) above obtained by polynomial mapping in fig. 5b20.9971, it is found that the coefficient of the equation (2) is larger than the coefficient of the equation (1). Preferably, the polynomial mapping is selected to linearly map the first sample temperature and the second sample temperature, which can improve the accuracy of the temperature control of the second position of the oven.
Therefore, the temperature mapping relation between the oven furnace core and the oven furnace angle can be accurately reduced by adopting the technology such as polynomial fitting, linear mapping and the like.
It should be noted that, by using the above method for developing a mapping relationship, development of a mapping relationship at any position inside the oven can be realized, so that accurate temperature control at any position inside the oven can be realized. In addition, the method for developing the mapping relation can also be applied to products such as microwave ovens and the like.
According to an embodiment of the present invention, the oven temperature control method further includes: storing the temperature collected by the first temperature sensor and the temperature collected by the second temperature sensor; and forming a table according to a preset format by using the cached temperature acquired by the first temperature sensor and the cached temperature acquired by the second temperature sensor.
Further, according to an embodiment of the present invention, the oven temperature control method further includes: and drawing and displaying a temperature curve through the stored temperature acquired by the first temperature sensor and the stored temperature acquired by the second temperature sensor.
Specifically, after the current temperature at the first position is detected by the first temperature sensor and the actual temperature at the second position is detected by the second temperature sensor, the temperature collected by the first temperature sensor and the temperature collected by the second temperature sensor are stored, a table is formed by the cached temperature collected by the first temperature sensor and the cached temperature collected by the second temperature sensor according to a preset format, or the stored temperature collected by the first temperature sensor and the stored temperature collected by the second temperature sensor are drawn into a temperature curve, and the temperature table or the temperature curve is displayed to a user through a display screen, so that visual operation and information display are realized, and the temperature data and the image of the temperature curve are stored in real time.
It should be noted that, in other embodiments of the present invention, other sensors (such as NTC temperature sensors, etc.) may be used instead of the thermocouple thermometers to achieve online temperature collection of the oven key components, and in addition, tools such as VB, C + +, C # and the like may be used instead of LabVIEW to develop the upper computer software.
In summary, according to the oven temperature control method of the embodiment of the present invention, the first temperature sensor detects the current temperature at the first location, and the mapping relationship between the temperature at the first location and the temperature at the second location is queried according to the current temperature to obtain the reference temperature at the second location, and the second temperature sensor detects the actual temperature at the second location, so that after the reference temperature and the actual temperature at the second location are obtained, the temperature control adjustment is performed on the second location according to the reference temperature and the actual temperature, thereby implementing the accurate control of the temperature at the second location of the oven, so as to cook delicious food.
