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.
A method of detecting a weight of food, an apparatus for detecting a weight of food, and a cooking appliance having the same according to embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method of detecting a weight of food according to an embodiment of the present invention.
In an embodiment of the present invention, the cooking appliance may be a microwave oven.
As shown in fig. 1, the method for detecting the weight of food according to the embodiment of the present invention may include the following steps:
s1, a first weight of the food measured by the weight sensor is obtained.
And S2, acquiring the position of the food on the bearing part. Taking a microwave oven as an example, the bearing part can be a turntable. The weight sensor is generally disposed at the center of the turntable, so the first weight detected is generally the weight of the food at the center of the detection.
According to one embodiment of the invention, acquiring the position of the food on the carrier comprises: the position is obtained by an infrared sensor or by a camera. As shown in fig. 2, the infrared sensor or the camera may be disposed at any position of the inner wall of the microwave oven, and is generally disposed on the opposite side of the turntable or on the side of the microwave oven for the convenience of detection.
The principle of acquiring the position by the infrared sensor is as follows: the infrared sensor is a sensor for detecting infrared radiation by using a physical effect exhibited by interaction between the infrared radiation and a substance, and in most cases, an electrical effect exhibited by the interaction is used; the infrared sensor utilizes the radiation heat effect to cause the temperature of the detecting element to rise after receiving the radiation energy, thereby causing the performance of the detector depending on the temperature to change. Radiation is detected by detecting a change in one of the properties, in most cases by pyroelectric change. When the element receives radiation, causing a physical change in the non-electrical quantity, the corresponding electrical quantity change can be measured by appropriate transformation.
By utilizing the principle, when no food is put into the microwave oven, the temperature of the turntable is detected by the infrared sensor; when food is put into the microwave oven, the infrared sensor can detect the temperature of the food, and the position of the food on the turntable can be distinguished by comparing the temperature of the turntable with the temperature of the food.
The principle of acquiring the position through the camera is as follows: the camera is through gathering the image on the carousel in real time to carry out identification analysis to the image, when food put into microwave oven, the camera will gather the image that has food, through carrying out the analysis to the image, can distinguish the position that food was put at the carousel.
And S3, compensating the first weight according to the position to obtain a second weight of the food.
According to an embodiment of the present invention, compensating the first weight according to the position includes:
and S31, determining the area of the bearing part to which the position belongs.
According to one embodiment of the invention, the carrier member is divided into a plurality of areas according to the distance from the centre point of the carrier member. Wherein the plurality of regions includes at least one set of region pairs, two regions of the region pairs being symmetric about a center point.
Specifically, in order to determine the specific position of the food more accurately, the carrying component is divided into areas, and different weight compensation modes are performed according to the area where the position of the food is located. For example, as shown in fig. 3, the center of the load bearing member is used as an origin, the regions are divided by different radii and extend outwards from the center, the radii gradually increase by the same value, the load bearing member is divided into 8 regions, a1, b1, c1, d1, a2, b2, c2 and d2, wherein a1 and a2 are symmetrical about the center point, b1 and b2 are symmetrical about the center point, c1 and c2 are symmetrical about the center point, and d1 and d2 are symmetrical about the center point. It should be noted that the bearing component may be divided into not only 8 regions, but also 6, 10, 12, etc., and fig. 3 is only one specific example.
By taking 8 areas and acquiring positions through the infrared sensor as an example, the infrared sensor rotates through the stepping motor to detect the temperatures of the 8 areas, and when the temperature of one area changes compared with the recorded temperature of the turntable and is inconsistent with the temperatures of other areas, the food can be judged to be placed in the areas of the turntable. For example, before food is put, the infrared sensor detects the temperature of the turntable, which is recorded as T1, after the food is put, the infrared sensor detects the temperatures of 8 areas, which are respectively recorded as Ta1, Tb1, Tc1, Td1, Ta2, Tb2, Tc2 and Td2, when the infrared sensor detects that the temperatures Tb2 and T of the b2 area are different and are different from the temperatures Ta1, Tb1, Tc1, Td1, Ta2, Tc2 and Td2, the food is put in the b2 area; for another example, when the infrared sensors detect that the temperatures Ta2, Tb2 in the a2 and b2 areas are different from T, and the temperatures Ta1, Tb1, Tc1, Td1, Tc2 and Td2 are different from each other, it indicates that food is placed in the a2 and b2 areas.
It should be noted that the infrared sensor detects the temperature at each position in each area, and the average temperature of all detected temperatures in each area can be taken as the temperature value in the area, so that the area where the food is located can be detected even if the food occupies two or more areas.
And S32, compensating the first weight according to the area.
According to one embodiment of the invention, compensating the first weight according to the region comprises: determining a corresponding compensation coefficient and a corresponding compensation value according to the area; and compensating the first weight according to the corresponding compensation coefficient and compensation value.
That is, the compensation coefficients and compensation values of the food weights corresponding to different areas are different, the specific positions of the food are obtained by the method, the corresponding compensation coefficients and compensation values are inquired according to the positions, the first weight is compensated to obtain the compensated second weight, and the reasonable cooking time is calculated according to the compensated second weight, so that the good cooking effect is obtained. Wherein the compensation factors and compensation values for the different regions corresponding to the weight of the food can be obtained by referring to the following table 1.
TABLE 1
As shown in table 1, w is the weight measured by the weight sensor, i.e., the first weight, k 1-k 12 are compensation coefficients, b 1-b 12 are compensation values, the compensation coefficients are related to the area where the food is located, and the compensation values are related to the weight w measured by the weight sensor, wherein k 1-k 12 and b 1-b 12 are data obtained through a large number of experimental tests. The position area of the food placed on the turntable is judged through the infrared sensor, and then corresponding formula compensation is carried out, so that the accurate weight of the food can be obtained.
In summary, the invention can judge the specific position of the food placed on the turntable by combining the weight sensor and the infrared sensor (or the camera), and then carry out weight compensation according to the distance deviating from the central point to obtain a value which is not much different from the actual weight of the food, so that the accurate weight of the food can be calculated by a formula compensation mode no matter whether the food is placed at the center of the turntable or not.
In summary, according to the method for detecting the weight of the food in the embodiment of the invention, the first weight of the food detected by the weight sensor is obtained, the position of the food on the bearing component is obtained, and the first weight is compensated according to the position to obtain the second weight of the food. Therefore, the method obtains the accurate weight of the food by judging the specific position of the food on the bearing part and compensating the weight of the food according to the specific position of the food, and further calculates the reasonable cooking time, so that the cooking effect is better.
