The thermal radiation and convection processes are affected by a variety of factors. Among the main factors affecting thermal radiation are: temperature, blackness, angular coefficient (geometric position), area size, intermediate medium, etc.; the main factors affecting thermal convection are: fluid flow state, presence or absence of phase change of fluid, physical properties of fluid, structural characteristics of heated surface, etc. Therefore, the area of the heated medium has an important influence on the absorption of temperature. The inventor researches and discovers that the cooking utensil temperature measuring equipment in the traditional technology has the defect of inaccurate heating temperature detection data because the influence caused by the heating area is neglected by directly carrying out single-point temperature acquisition by adopting the thermocouple, and the large-area heating condition of food cannot be accurately evaluated. Based on this, the application provides cooking utensil temperature measurement equipment, test method, testing arrangement and cooking utensil, replaces food with the mica sheet and carries out the culinary art test to according to the heating temperature of mica sheet position, with the accuracy that improves cooking utensil test in-process heating temperature detection data.
In one embodiment, the present application provides a cooking appliance temperature measurement device comprising a mica sheet and a probe. The mica sheet is arranged on a vessel of a cooking appliance to be measured. The detector is used to detect the properties of the mica sheets during the cooking test. The properties of the mica sheets during the cooking test are used to determine the heating temperature of the corresponding location.
The specific type of the cooking appliance to be measured is not unique, and may be, for example, an oven, a steam box, an intelligent electric cooker, or the like. Correspondingly, the utensil of the cooking appliance to be measured can be a grill in an oven, a steaming tray in a steam box or a cooker body of an intelligent electric cooker. The mica is composed of multi-silicon white mica, quartz, garnet and rutile, has the functions of insulation and low-loss thermal resistance, and has high cost performance. The mica sheet is a sheet mica with the thickness and length and the ratio of the thickness to the width smaller than a set threshold value, so as to simulate the scene that food is heated in a large area in the cooking utensil as much as possible. The mica sheet can be natural mica sheet or synthetic mica sheet. The natural mica sheet is a mica part with a certain thickness and a certain shape, is a natural mineral product, and has the characteristics of no pollution, insulation and good voltage resistance. The synthetic mica sheet (also called synthetic fluorophlogopite) has the characteristics of purity, high transparency, high temperature resistance, strong acid and alkali resistance, high chemical stability and good electrical insulation performance. Further, a plurality of mica sheets can be used, and the mica sheets are respectively arranged at different positions of the vessel of the cooking appliance to be measured so as to obtain the heating temperatures of the plurality of positions.
In one embodiment, the cooking appliance under test is an oven; the mica sheets are arranged on a grill of the oven. Wherein the arrangement of the mica sheets on the grill is not exclusive. For example, when one mica sheet is used, the mica sheet may be disposed in the middle or both sides of the grill; when using a plurality of mica sheets, can arrange the certain clearance array in mica sheet interval on the gridion, also can be through the concatenation, with a plurality of mica sheet edge to edge, constitute a whole, arrange in the centre or both sides of gridion. In one embodiment, the number of mica sheets is two or more, each of which is layered over the grill. Wherein, the mica sheet is fully paved on the grill, which means that the mica sheet completely covers the whole grill. Specifically, the number and the arrangement mode of the mica sheets can be determined according to the size of a single mica sheet and the size of the grill, so that the mica sheets are fully paved on the whole grill, the attribute of the mica sheets of the whole grill in the cooking test process is obtained, the heating temperature information of the whole grill is further obtained, the cooking conditions of food on different positions of the grill are determined, and the scientific comprehensiveness of the cooking appliance test method is improved.
Since the mica sheets have good heat conduction performance, the temperature of different positions of the same mica sheet tends to be consistent. Based on the method, the smaller the length and width dimensions of the mica sheet are, the higher the detection precision is, but the larger the cutting difficulty is, and based on the method, the detection precision and the cutting difficulty can be comprehensively considered to determine the size of the mica sheet. In one embodiment, the mica sheets are sized in accordance with the testing requirements of the corresponding cooking appliance to be tested. The test requirement can be an enterprise test requirement or a national standard test requirement. Taking the cooking appliance to be tested as an oven as an example, if the enterprise mapping test requirement of a certain company specifies that the food used for the cooking test is a white bread slice, and the size of the white bread slice is 7cm by 7 cm. The mica sheets were also cut to a size of 7cm by 7cm, laid on a grill, and cooking tests were performed using the mica sheets instead of the white bread sheets. The size of the mica sheet is consistent with the test requirement of the corresponding cooking utensil to be tested, and the mica sheet can be as close as possible to the standard test requirement of the corresponding cooking utensil, thereby being beneficial to improving the accuracy of the cooking test result.
Further, the attribute of the mica sheet in the cooking test process can be color attribute, size attribute or temperature attribute, correspondingly, the detector can be an infrared detector for detecting color change of the mica sheet, can also be a size detector for detecting size change of the mica sheet, such as an inductance micrometer or a machine vision detection system, and can also be a temperature sensor for detecting temperature change of the mica sheet. In one embodiment, the attribute of the mica sheet during the cooking test is a color attribute and the detector is an infrared detector. Specifically, the mica sheet has good heat resistance, cannot be dissolved in a high-temperature environment, but can show different colors along with the rise of the temperature, so that the color of the mica sheet can be acquired by using an infrared detector, the temperature of the mica sheet is determined according to the preset corresponding relation between the color of the mica sheet and the temperature, and the heating temperature of the corresponding position is further determined. The color of the mica sheet is detected through the infrared detector, and then the temperature of the mica sheet is determined.
Above-mentioned cooking utensil temperature measuring equipment, the configuration mica sheet arranges on being used for placing on the household utensils of being cooked food, and the configuration detector surveys the attribute of mica sheet in the culinary art test procedure, confirm the heating temperature of mica sheet position according to the attribute of mica sheet, be equivalent to replace food with the mica sheet and cook the test, and according to the mica sheet attribute situation of change, confirm the heating temperature situation of change of mica sheet position, because the flaky attribute and the good heat conductivility of mica sheet, can simulate the large tracts of land process of being heated of cooking in-process food, be favorable to improving the accuracy of the temperature detection data that heats in the cooking utensil test procedure.
In one embodiment, as shown in fig. 1, there is provided a cooking appliance testing method including steps S200 to S600.
Step S200: and acquiring the attribute of the mica sheet in the testing process of the cooking appliance to be tested, and determining the temperature of the mica sheet according to the attribute.
Wherein, the mica sheet is arranged on a vessel of the cooking utensil to be measured. The specific type of cooking appliance to be tested is not exclusive and may be, for example, an oven, a steam box, an intelligent electric cooker or the like. Correspondingly, the utensil of the cooking appliance to be measured can be a grill in an oven, a steaming tray in a steam box or a cooker body of an intelligent electric cooker. The mica sheet is a sheet mica with the thickness and length and the ratio of the thickness to the width smaller than a set threshold value, so as to simulate the scene that food is heated in a large area in the cooking utensil as much as possible. The mica sheet can be natural mica sheet or synthetic mica sheet. Further, a plurality of mica sheets can be used, and the mica sheets are respectively arranged at different positions of the vessel of the cooking appliance to be measured so as to obtain the heating temperatures of the plurality of positions.
In one embodiment, the cooking appliance under test is an oven; the mica sheets are arranged on a grill of the oven. Wherein the arrangement of the mica sheets on the grill is not exclusive. For example, when one mica sheet is used, the mica sheet may be disposed in the middle or both sides of the grill; when using a plurality of mica sheets, can arrange the certain clearance array in mica sheet interval on the gridion, also can be through the concatenation, with a plurality of mica sheet edge to edge, constitute a whole, arrange in the centre or both sides of gridion. In one embodiment, the number of mica sheets is two or more, each of which is layered over the grill. Wherein, the mica sheet is fully paved on the grill, which means that the mica sheet completely covers the whole grill. Specifically, the number and the arrangement mode of the mica sheets can be determined according to the size of a single mica sheet and the size of the grill, so that the mica sheets are fully paved on the whole grill, the attribute of the mica sheets of the whole grill in the cooking test process is obtained, the heating temperature information of the whole grill is further obtained, the cooking conditions of food on different positions of the grill are determined, and the scientific comprehensiveness of the cooking appliance test method is improved.
Since the mica sheets have good heat conduction performance, the temperature of different positions of the same mica sheet tends to be consistent. Based on the method, the smaller the length and width dimensions of the mica sheet are, the higher the detection precision is, but the larger the cutting difficulty is, and based on the method, the detection precision and the cutting difficulty can be comprehensively considered to determine the size of the mica sheet. In one embodiment, the mica sheets are sized in accordance with the testing requirements of the corresponding cooking appliance to be tested. The test requirement can be an enterprise test requirement or a national standard test requirement. Taking the cooking appliance to be tested as an oven as an example, if the enterprise mapping test requirement of a certain company specifies that the food used for the cooking test is a white bread slice, and the size of the white bread slice is 7cm by 7 cm. The mica sheets were also cut to a size of 7cm by 7cm, laid on a grill, and cooking tests were performed using the mica sheets instead of the white bread sheets. The size of the mica sheet is consistent with the test requirement of the corresponding cooking utensil to be tested, and the mica sheet can be as close as possible to the standard test requirement of the corresponding cooking utensil, thereby being beneficial to improving the accuracy of the cooking test result.
Further, the property of the mica sheet during the cooking test may be a color property, a size property or a temperature property. Specifically, the attribute of the mica sheet in the cooking test process can be obtained through detection by the corresponding detector and sent to the control unit, and then the temperature of the mica sheet is determined by the control unit according to the attribute and the corresponding relation between the pre-stored attribute of the mica sheet and the temperature. Take the case where the detected attribute is a size attribute as an example. The expansion and contraction phenomenon of an object can occur due to temperature change, specifically, expansion and contraction are realized, the change capability of the object is expressed by the change of a length value caused by unit temperature change under certain pressure, namely, the thermal expansion coefficient, and the mica sheet is not exceptional. Based on the method, the size of the mica sheet in the cooking test process can be collected by a size detector, and the temperature of the mica sheet is determined by combining the corresponding relation between the size of the mica sheet and the temperature. The corresponding relation between the size of the mica sheet and the temperature is determined according to the initial size, the initial temperature and the thermal expansion coefficient of the mica sheet.
Step S400: and determining the heating temperature of the position of the mica sheet according to the temperature of the mica sheet.
Specifically, the heating temperature mode for determining the position of the mica sheet is not unique according to the temperature of the mica sheet. For example, the temperature of the mica sheet can be simply equal to the heating temperature of the position of the mica sheet, so that the calculation process is simplified, and the working efficiency is improved; error coefficients can also be introduced according to the property difference of food for cooking test specified in the test requirements of the mica sheet and the enterprise/national standards, such as specific heat capacity, heat conductivity and the like, and the heating temperature of the mica sheet can be obtained by combining the temperature and the error coefficients of the mica sheet.
Step S600: and obtaining and outputting a cooking test result of the cooking appliance to be tested according to the heating temperature.
In the narrow sense of cooking, the food is cooked by heating the food. Based on this, taking food as the research object, the cooking process can be expressed as the temperature variation process of food caused by heating, and the temperature variation process of food is directly related to the heating temperature of the cooking process, which will also ultimately affect the cooking effect of food. Taking the case that the cooking appliance to be tested is an oven and the food for cooking test is a white bread slice as an example: if the heating temperature is too low, the white bread sheet may not be colored; if the heating temperature is too high, the white bread slices may be scorched; if the heating temperature rises too slowly, the white bread slices may lose too much water and affect the taste. In a word, according to the cooking requirement of the corresponding food, the relation between the heating temperature change condition and the cooking effect can be established.
