Description
技术领域technical field
本发明涉及微波技术领域，具体地，涉及一种微波加热控制系统、微波加热控制方法及微波炉。The invention relates to the field of microwave technology, in particular to a microwave heating control system, a microwave heating control method and a microwave oven.
背景技术Background technique
在传统的烹饪方式中，为了使食物较快变熟，烹饪食物的温度通常达到100度左右(如蒸、煮和微波加热等)，或者高于100℃(如高压蒸煮、煎、炒和炸等)，即，以固定温度对食物进行加热，在该过程中，食物本身的温度随着加热过程不断提升，无法对温度进行有效控制。而过高的食物烹饪温度不仅容易对食物中的一些营养成分造成破坏，甚至还会产生对人体健康有害的物质。例如，微波烹饪方式作为一种广泛使用的食物烹饪方式，具有加热速度快、加热均匀、使用方便等优点，然而，在使用微波炉对食物进行烹饪的过程中，通常也是直接单一地按照能使食物快速变熟的温度(如100℃以上的温度)对食物进行加热，同样不能对温度进行有效控制，进而会造成食物中大部分营养成分损失，并且口感也会变差。In the traditional cooking method, in order to make the food cook faster, the temperature of the cooking food is usually around 100 degrees (such as steaming, boiling and microwave heating, etc.), or higher than 100 degrees (such as high-pressure cooking, frying, frying and frying). etc.), that is, the food is heated at a fixed temperature. In this process, the temperature of the food itself is continuously raised along with the heating process, and the temperature cannot be effectively controlled. Excessive food cooking temperature not only easily destroys some nutrients in food, but also produces substances harmful to human health. For example, as a widely used food cooking method, microwave cooking has the advantages of fast heating speed, uniform heating, and convenient use. Rapidly ripening temperatures (such as temperatures above 100° C.) heat the food, and the temperature cannot be effectively controlled, which will cause most of the nutrients in the food to be lost, and the taste will also deteriorate.

具体实施方式Detailed ways
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
图1是根据本发明一种实施方式的微波加热控制系统的方框图。FIG. 1 is a block diagram of a microwave heating control system according to an embodiment of the present invention.
如图1所示，本发明提供的微波加热控制系统包括：一个或多个温度检测装置10，用于检测待烹饪食物的温度；以及控制装置20，与所述温度检测装置10连接，用于在所检测的温度大于或等于所述待烹饪食物所需维持的预定温度T时控制微波加热装置停止加热并控制所述微波加热装置执行恒温操作达预定时间t。As shown in FIG. 1 , the microwave heating control system provided by the present invention includes: one or more temperature detection devices 10 for detecting the temperature of the food to be cooked; and a control device 20 connected with the temperature detection devices 10 for When the detected temperature is greater than or equal to the predetermined temperature T required to be maintained by the food to be cooked, the microwave heating device is controlled to stop heating and the microwave heating device is controlled to perform a constant temperature operation for a predetermined time t.
通过温度检测装置10对烹饪过程中的食物的温度进行检测，而控制装置20在食物的所检测的温度大于食物所需维持的预定温度时控制微波加热装置停止加热并控制所述微波加热装置执行恒温操作达预定时间，使得食物温度保持在期望温度达预定时间，这样既能够保证食物变熟，又能够确保食物不会长时间在高温下加热，从而实现了烹饪过程中对温度的精确控制，进而减少了食品因高温而造成的营养成分损失，且能够确保食物口感。The temperature of the food in the cooking process is detected by the temperature detection device 10, and the control device 20 controls the microwave heating device to stop heating and controls the microwave heating device to perform The constant temperature operation lasts for a predetermined time, so that the temperature of the food is kept at the desired temperature for a predetermined time, which can not only ensure that the food is cooked, but also ensure that the food will not be heated at high temperature for a long time, thus realizing the precise control of the temperature during the cooking process. In turn, the loss of nutrients in the food due to high temperature is reduced, and the taste of the food can be ensured.
根据本发明一种实施方式，当仅检测到所述待烹饪食物的一个温度时将该一个温度作为所述待烹饪食物的所检测的温度，当检测到所述待烹饪食物的多个温度时将多个温度中的最小值作为所述待烹饪食物的所检测的温度。According to one embodiment of the present invention, when only one temperature of the food to be cooked is detected, this one temperature is taken as the detected temperature of the food to be cooked, and when multiple temperatures of the food to be cooked are detected The minimum value among the plurality of temperatures is taken as the detected temperature of the food to be cooked.
具体地，对于温度检测装置10的数量，本领域技术人员可以根据实际需要来选择。在采用一个温度检测装置10检测一次温度的情况下，直接将该检测的温度作为待烹饪食物的所检测的温度。可替换地，也可以采用一个温度检测装置10对食物温度进行多次检测得到多个检测的温度，然后将多个检测的温度中的最小值作为待烹饪食物的所检测的温度。在采用多个温度检测装置10检测温度的情况下，可以将多个温度检测装置10检测的温度中的最小值作为待烹饪食物的所检测的温度。Specifically, those skilled in the art can select the number of temperature detection devices 10 according to actual needs. In the case of using one temperature detection device 10 to detect the primary temperature, the detected temperature is directly used as the detected temperature of the food to be cooked. Alternatively, one temperature detection device 10 may also be used to detect the temperature of the food multiple times to obtain multiple detected temperatures, and then use the minimum value of the multiple detected temperatures as the detected temperature of the food to be cooked. In the case of using multiple temperature detection devices 10 to detect the temperature, the minimum value among the temperatures detected by the multiple temperature detection devices 10 may be used as the detected temperature of the food to be cooked.
此外，在执行恒温操作之前微波加热装置的加热过程为食物的升温操作过程(在该过程中，使食品整体被加热)，升温操作过程采用的微波输出功率可以大于或等于恒温操作过程中微波加热装置采用的微波输出功率。In addition, before performing the constant temperature operation, the heating process of the microwave heating device is the temperature rise operation process of the food (in this process, the food is heated as a whole), and the microwave output power used in the temperature rise operation process can be greater than or equal to the microwave heating during the constant temperature operation process. The microwave output power used by the device.
根据本发明一种实施方式，所述控制装置20控制所述微波加热装置执行恒温操作达预定时间t包括：在所述预定时间t内，当所检测的温度小于所述预定温度T时，所述控制装置20控制所述微波加热装置开始加热，直到所检测的温度大于或等于所述预定温度T，所述控制装置20控制所述微波加热装置停止加热。According to an embodiment of the present invention, the control device 20 controlling the microwave heating device to perform constant temperature operation for a predetermined time t includes: within the predetermined time t, when the detected temperature is lower than the predetermined temperature T, the The control device 20 controls the microwave heating device to start heating until the detected temperature is greater than or equal to the predetermined temperature T, and the control device 20 controls the microwave heating device to stop heating.
通过控制装置20执行上述的控制过程，只要在预定时间内食物的温度降低为小于预定温度，微波加热装置就开始加热，直到食物的温度上升为大于或等于预定温度时微波加热装置停止加热。这样，可以确保食物在预定时间内保持在恒定温度下，避免了食物因温度过低造成的不熟以及因温度过高造成的营养成分流失等问题。并且，在该过程中，即便微波加热装置停止微波功率输出，食品本身由于具有一定温度，因而可以进行自身区域内的热传导，一定程度上可以增加食品的受热均匀性。Through the control device 20 executing the above control process, as long as the temperature of the food decreases to less than the predetermined temperature within a predetermined time, the microwave heating device starts heating, until the temperature of the food rises to be greater than or equal to the predetermined temperature, the microwave heating device stops heating. In this way, it can be ensured that the food is kept at a constant temperature within a predetermined time, avoiding problems such as undercooking of the food due to too low temperature and loss of nutrients caused by too high temperature. Moreover, in this process, even if the microwave heating device stops the microwave power output, the food itself has a certain temperature, so it can conduct heat conduction in its own area, which can increase the heating uniformity of the food to a certain extent.
根据本发明一种实施方式，可替换地，所述控制装置控制所述微波加热装置执行恒温操作达预定时间t包括：在所述预定时间t内，当所检测的温度小于T-△T时，所述控制装置控制所述微波加热装置开始加热，直到所检测的温度大于或等于T+△T，所述控制装置控制所述微波加热装置停止加热，其中△T为温度变化量。According to an embodiment of the present invention, alternatively, the control device controlling the microwave heating device to perform a constant temperature operation for a predetermined time t includes: within the predetermined time t, when the detected temperature is less than T-ΔT, The control device controls the microwave heating device to start heating until the detected temperature is greater than or equal to T+ΔT, and the control device controls the microwave heating device to stop heating, where ΔT is the temperature change.
通过在恒温操作过程中进一步引入温度变化量△T来进行温度判断，可以避免食物的温度虽然低于预定温度但仍然非常接近预定温度的情况下或者是食物的温度虽然刚加热达到预定温度但很快降低至低于预定温度的情况下微波加热装置频繁执行加热操作引起的资源浪费，同时也可以避免加热装置频繁加热对装置本身的损害。By further introducing the temperature change ΔT in the constant temperature operation process to judge the temperature, it can avoid the situation that the temperature of the food is lower than the predetermined temperature but still very close to the predetermined temperature or the temperature of the food is just heated to the predetermined temperature but is very close to the predetermined temperature. The waste of resources caused by the frequent heating operation of the microwave heating device when the temperature is quickly lowered to below the predetermined temperature can also avoid the damage to the device itself caused by the frequent heating of the heating device.
根据本发明一种实施方式，该系统还包括计时器(未示出)，与控制装置20连接，用于对开始执行恒温操作到该恒温操作结束所持续的预定时间t进行计时。当对该预定时间t的计时结束，表示烹饪过程结束。According to one embodiment of the present invention, the system further includes a timer (not shown), connected to the control device 20, for timing the predetermined time t from the start of the constant temperature operation to the end of the constant temperature operation. When the counting of the predetermined time t ends, it means that the cooking process ends.
根据本发明一种实施方式，△T的范围可以为0.5℃≤△T≤5℃。本领域技术人员可以根据食物的种类以及温度检测装置10的检测精度来选取△T的值。According to an embodiment of the present invention, the range of ΔT may be 0.5°C≦ΔT≦5°C. Those skilled in the art can select the value of ΔT according to the type of food and the detection accuracy of the temperature detection device 10 .
根据本发明一种实施方式，所述预定温度T的范围可以为65℃≤T≤100℃，所述预定时间t的范围可以为0min＜t≤60min。According to an embodiment of the present invention, the range of the predetermined temperature T may be 65°C≤T≤100°C, and the range of the predetermined time t may be 0min<t≤60min.
不同的食物具有不同的烹饪特性，因此本领域技术人员可以根据食物的烹饪特性来设定该食物对应的预定温度范围以及预定时间范围。此外，由于在不同的烹饪时间和温度下烹饪，食物口感也是有差异的(例如，低温长时间烹饪的食物口感较硬，而高温短时间的烹饪食物的口感较软)，因此本领域技术人员可以根据实际需要来设定预定温度值以及预定时间值。Different foods have different cooking characteristics, so those skilled in the art can set a predetermined temperature range and a predetermined time range corresponding to the food according to the cooking characteristics of the food. In addition, due to cooking at different cooking times and temperatures, the taste of food is also different (for example, the taste of food cooked at low temperature for a long time is hard, while the taste of food cooked at high temperature for a short time is soft), so those skilled in the art The predetermined temperature value and the predetermined time value can be set according to actual needs.
上述的预定温度T、预定时间t、温度变化量△T可以由用户通过人机交互界面输入至系统中，也可以预先存储在微波加热控制系统的存储装置中。由此，用户可以根据个人喜好设定期望的温度及保持该温度所持续的时间，也可以使用已经设定好的温度和保持该温度所持续的时间。The aforementioned predetermined temperature T, predetermined time t, and temperature change ΔT can be input into the system by the user through the man-machine interface, or can be pre-stored in the storage device of the microwave heating control system. Thus, the user can set the desired temperature and the duration of maintaining the temperature according to personal preferences, or use the temperature that has already been set and the duration of maintaining the temperature.
根据本发明一种实施方式，所述温度检测装置10为红外温度传感器。红外温度传感器具有较高的检测精度。通过在本发明中应用红外温度传感器检测待烹饪食物的温度，可以更准确地控制整个烹饪过程的温度。According to one embodiment of the present invention, the temperature detection device 10 is an infrared temperature sensor. Infrared temperature sensors have high detection accuracy. By using the infrared temperature sensor in the present invention to detect the temperature of the food to be cooked, the temperature of the whole cooking process can be controlled more accurately.
本领域技术人员应当理解，上述对预定温度T、预定时间t、温度变化量△T的范围的描述以及选用红外温度传感器作为温度检测装置10仅仅是示例性的，并非用于限定本发明。Those skilled in the art should understand that the above descriptions of the predetermined temperature T, the predetermined time t, the range of the temperature change ΔT and the selection of the infrared temperature sensor as the temperature detection device 10 are only exemplary and not intended to limit the present invention.
本发明还提供了一种微波炉，包括上述实施方式中的微波加热控制系统。The present invention also provides a microwave oven, including the microwave heating control system in the above embodiment.
本发明的微波加热控制系统适用于各种类型的微波炉(例如，变频微波炉、非变频微波炉)。The microwave heating control system of the present invention is applicable to various types of microwave ovens (for example, frequency conversion microwave ovens, non-frequency conversion microwave ovens).

通过对烹饪过程中的食物的温度进行检测，在食物的所检测的温度大于食物所需维持的预定温度时控制微波加热装置停止加热并控制所述微波加热装置执行恒温操作达预定时间，使得食物温度保持在期望温度达预定时间，这样既能够保证食物变熟，又能够确保食物不会长时间在高温下加热，从而实现了烹饪过程中对温度的精确控制，进而减少了食品因高温而造成的营养成分损失，且能够确保食物口感。By detecting the temperature of the food during the cooking process, when the detected temperature of the food is greater than the predetermined temperature that the food needs to maintain, the microwave heating device is controlled to stop heating and the microwave heating device is controlled to perform a constant temperature operation for a predetermined time, so that the food The temperature is kept at the desired temperature for a predetermined time, which can not only ensure that the food is cooked, but also ensure that the food will not be heated at high temperature for a long time, so as to realize the precise control of the temperature during the cooking process, thereby reducing the food caused by high temperature. Loss of nutrients, and can ensure the taste of food.
根据本发明一种实施方式，当仅检测到所述待烹饪食物的一个温度时将该一个温度作为所述待烹饪食物的所检测的温度，当检测到所述待烹饪食物的多个温度时将多个温度中的最小值作为所述待烹饪食物的所检测的温度。According to one embodiment of the present invention, when only one temperature of the food to be cooked is detected, this one temperature is taken as the detected temperature of the food to be cooked, and when multiple temperatures of the food to be cooked are detected The minimum value among the plurality of temperatures is taken as the detected temperature of the food to be cooked.
其中，在执行恒温操作之前微波加热装置的加热过程为食物的升温操作过程(在该过程中，使食品整体被加热)，升温操作过程采用的微波输出功率可以大于或等于恒温操作过程中微波加热装置采用的微波输出功率。Wherein, before performing the constant temperature operation, the heating process of the microwave heating device is the temperature rise operation process of the food (in this process, the food is heated as a whole), and the microwave output power used in the temperature rise operation process can be greater than or equal to the microwave heating during the constant temperature operation process. The microwave output power used by the device.
根据本发明一种实施方式，在步骤S202中，控制所述微波加热装置执行恒温操作达预定时间t包括：在所述预定时间t内，当所检测的温度小于所述预定温度T时，控制所述微波加热装置开始加热，直到所检测的温度大于或等于所述预定温度T，控制所述微波加热装置停止加热。According to one embodiment of the present invention, in step S202, controlling the microwave heating device to perform a constant temperature operation for a predetermined time t includes: within the predetermined time t, when the detected temperature is lower than the predetermined temperature T, controlling the The microwave heating device starts heating until the detected temperature is greater than or equal to the predetermined temperature T, and the microwave heating device is controlled to stop heating.
通过执行上述步骤，可以确保食物在预定时间内保持在恒定温度下，避免了食物因温度过低造成的不熟以及因温度过高造成的营养成分流失等问题。并且，在该过程中，即便微波加热装置停止微波功率输出，食品本身由于具有一定温度，因而可以进行自身区域内的热传导，一定程度上可以增加食品的受热均匀性。By performing the above steps, it is possible to ensure that the food is kept at a constant temperature within a predetermined time, avoiding problems such as undercooking of the food due to too low temperature and loss of nutrients caused by too high temperature. Moreover, in this process, even if the microwave heating device stops the microwave power output, the food itself has a certain temperature, so it can conduct heat conduction in its own area, which can increase the heating uniformity of the food to a certain extent.
根据本发明一种实施方式，可替换地，在步骤S202中，控制所述微波加热装置执行恒温操作达预定时间t包括：在所述预定时间t内，当所检测的温度小于T-△T时，控制所述微波加热装置开始加热，直到所检测的温度大于或等于T+△T，控制所述微波加热装置停止加热，其中△T为温度变化量。According to one embodiment of the present invention, alternatively, in step S202, controlling the microwave heating device to perform a constant temperature operation for a predetermined time t includes: within the predetermined time t, when the detected temperature is less than T-ΔT , controlling the microwave heating device to start heating until the detected temperature is greater than or equal to T+ΔT, controlling the microwave heating device to stop heating, wherein ΔT is the temperature change amount.
通过在恒温操作过程中进一步引入温度变化量△T来进行温度判断，可以避免食物的温度虽然低于预定温度但仍然非常接近预定温度的情况下或者是食物的温度虽然刚加热达到预定温度但很快降低至低于预定温度的情况下微波加热装置频繁执行加热操作引起的资源浪费，同时也可以避免加热装置频繁加热对装置本身的损害。By further introducing the temperature change ΔT in the constant temperature operation process to judge the temperature, it can avoid the situation that the temperature of the food is lower than the predetermined temperature but still very close to the predetermined temperature or the temperature of the food is just heated to the predetermined temperature but is very close to the predetermined temperature. The waste of resources caused by the frequent heating operation of the microwave heating device when the temperature is quickly lowered to below the predetermined temperature can also avoid the damage to the device itself caused by the frequent heating of the heating device.
根据本发明一种实施方式，△T的范围为0.5℃≤△T≤5℃。本领域技术人员可以根据食物的种类以及温度检测装置10的检测精度来选取△T的值。According to an embodiment of the present invention, the range of ΔT is 0.5°C≦ΔT≦5°C. Those skilled in the art can select the value of ΔT according to the type of food and the detection accuracy of the temperature detection device 10 .
根据本发明一种实施方式，所述预定温度T的范围为65℃≤T≤100℃，所述预定时间t的范围为0min＜t≤60min。According to an embodiment of the present invention, the range of the predetermined temperature T is 65°C≤T≤100°C, and the range of the predetermined time t is 0min<t≤60min.
