背景技术Background technique
随着科技的大力发展，目前加热方式也越来越多，例如微波加热、光波加热等等。但是，加热均匀性一直是加热行业中极为关注的特性，尤其是微波加热行业中，从出现微波加热到现在，加热均匀性的问题一直是困扰工程师的难题。With the vigorous development of science and technology, there are more and more heating methods, such as microwave heating, light wave heating and so on. However, heating uniformity has always been a feature of great concern in the heating industry, especially in the microwave heating industry. From the emergence of microwave heating to the present, the problem of heating uniformity has always been a difficult problem for engineers.
常见的情况是，当你加热一样食物(例如蛋糕)时，需要通过借助各种辅助件(例如搅拌片、转盘)进行相应的辅助动作，以使其仅可能地实现均匀加热。但同样状态下换上另一种食物(例如牛肉)，由于食物本身的特性，是无法复制之前的加热过程来实现相同的加热效果的。A common situation is that when you heat a food (such as a cake), you need to perform corresponding auxiliary actions with the help of various auxiliary parts (such as a stirring plate, a turntable), so that it can only achieve uniform heating as much as possible. However, another kind of food (such as beef) is replaced in the same state. Due to the characteristics of the food itself, it is impossible to copy the previous heating process to achieve the same heating effect.

具体实施方式detailed description
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是根据本发明提供的加热装置的结构示意图。如图1所示，本发明提供的加热装置可以包括：至少两个加热源11；控制器12，用于根据所述待加热物所需功率控制加热源以起始功率开始加热；以及温度检测装置13，检测所述待加热物的不同部位或所述多个待加热物中的不同待加热物的温度，其中，所述控制器12还用于在所检测的各温度之间的差值超过预设范围的情况下，控制所述加热源按照确定的温度最低的待加热物的部位或待加热物所对应的加热频率和加热相位进行加热。Fig. 1 is a schematic structural view of a heating device provided according to the present invention. As shown in Figure 1, the heating device provided by the present invention may include: at least two heating sources 11; a controller 12, which is used to control the heating source to start heating with the initial power according to the required power of the object to be heated; and temperature detection A device 13 for detecting the temperature of different parts of the object to be heated or the temperature of different objects to be heated among the plurality of objects to be heated, wherein the controller 12 is also used for the difference between the detected temperatures If it exceeds the preset range, the heating source is controlled to heat according to the determined part of the object to be heated with the lowest temperature or the heating frequency and heating phase corresponding to the object to be heated.
加热源的每一种频率、相位的组合能够在加热装置的加热室内形成对应的场分布，如果把加热室分成若干区域，每一个区域的电磁场强度是不一致的。当加热源的相位、频率变化时，各区域的电磁场强度也会发生变化。相应地，放置在场强强的地方的待加热物的温升速度会更快，因而同一时间内产生的温升最大；而放置在场强较弱的地方的待加热物的温升速度则较慢(对于同一种或相近的物质)，因而同一时间内产生的温升最小。因此只要能检测温度，并且能依据温度调节加热源的工作状态，以使得放置在加热室中的待加热物的各部分(或多个待加热物)能够在加热完成后控制在较小的温度差内(应该注意的是，不同待加热物温度差要求可以不同)，从而能够实现均匀加热。Each frequency and phase combination of the heating source can form a corresponding field distribution in the heating chamber of the heating device. If the heating chamber is divided into several regions, the electromagnetic field strength of each region is inconsistent. When the phase and frequency of the heating source change, the electromagnetic field strength in each area will also change. Correspondingly, the temperature rise rate of the object to be heated placed in a place with a strong field strength will be faster, so the temperature rise will be the largest at the same time; while the temperature rise rate of the object to be heated placed in a place with a weaker field strength will be Slower (for the same or similar substances), so the temperature rise produced in the same time is the smallest. Therefore, as long as the temperature can be detected and the working state of the heating source can be adjusted according to the temperature, each part of the object to be heated (or multiple objects to be heated) placed in the heating chamber can be controlled at a lower temperature after the heating is completed. (It should be noted that the temperature difference requirements of different objects to be heated can be different), so that uniform heating can be achieved.
其中，所述温度检测装置13还用于在预定周期内扫描覆盖所述待加热物所占区域的热点的温度；所述控制器12还用于控制加热源的频率和相位改变，直至确定所述预定周期内使所述待加热物的一部位或所述多个待加热物中的一待加热物的温升最大的加热源的频率和相位，将该频率和相位确定为所述待加热物的该部位或所述多个待加热物中的该待加热物对应的加热频率和加热相位。所述温度扫描装置可以为多点温度传感器或热成像设备，其中，热成像设备可以很容易的检测并记录某一区域的温度，多点温度传感器，则需要加上一定的算法，使被采集的数据按照物理位置记录温度相近的点，关于热成像设备和多点温度传感器为现有器件，出于简洁的目的，于此不再赘述。Wherein, the temperature detection device 13 is also used to scan the temperature of the hot spot covering the area occupied by the object to be heated within a predetermined period; the controller 12 is also used to control the frequency and phase change of the heating source until the determined The frequency and phase of the heating source that maximizes the temperature rise of a part of the object to be heated or an object to be heated among the plurality of objects to be heated within the predetermined period are determined as the frequency and phase of the object to be heated The heating frequency and the heating phase corresponding to the part of the object or the object to be heated among the plurality of objects to be heated. The temperature scanning device can be a multi-point temperature sensor or a thermal imaging device, wherein the thermal imaging device can easily detect and record the temperature in a certain area, and a multi-point temperature sensor needs to add a certain algorithm to make the collected According to the physical location of the data, the points with similar temperatures are recorded. The thermal imaging equipment and the multi-point temperature sensor are existing devices. For the purpose of brevity, no more details are given here.
此外，为了实现加热源的相位改变，所述加热装置11还可以包括移相器。In addition, in order to change the phase of the heating source, the heating device 11 may further include a phase shifter.
所述控制器12还用于确定所述加热源开始加热时的频率和相位以使得加热源的入射功率最高且反射功率最小，以便能够实现快速加热。另外，在所述待加热物达到预设温度后，所述控制器12可以控制所述加热源停止加热。The controller 12 is also used to determine the frequency and phase when the heating source starts heating so that the incident power of the heating source is the highest and the reflected power is the smallest, so as to realize rapid heating. In addition, after the object to be heated reaches a preset temperature, the controller 12 may control the heating source to stop heating.
为了能够使加热源工作在相同频率下，至少两个加热源11可以由同一微波信号产生模块产生，加热源11可以是微波源。In order to enable the heating sources to work at the same frequency, at least two heating sources 11 can be generated by the same microwave signal generating module, and the heating sources 11 can be microwave sources.
加热装置11还可以包括用于所述加热源向加热装置馈入能量的馈入口，至少两个馈入口被设置在加热室的壁上，其数量可以与加热源的数量一致；馈入口之间需要保证良好的隔离度，例如，在加热装置为半导体微波加热设备的情况下，馈入口之间的隔离度可以小于-15dB。The heating device 11 may also include a feeding port for the heating source to feed energy to the heating device, at least two feeding ports are arranged on the wall of the heating chamber, and the number thereof may be consistent with the number of the heating source; between the feeding ports It is necessary to ensure good isolation. For example, if the heating device is a semiconductor microwave heating device, the isolation between feed ports may be less than -15dB.
在确定所述待加热物的不同部位或所述多个待加热物中的不同待加热物对应的加热频率和加热相位时，由于目的并不在于对待加热物进行加热，因此控制器12可以控制所述加热源以较低的预设加热功率(例如总功率小于100W)进行加热，以节约能源，当然，实际上可以依据被加热物的特性来设置加热功率，在温度高的情况下不会引起物质变性也可以适当的增加功率；在确定所述加热频率和所述加热相位之后，控制器12可以根据所述待加热物的种类及所需的加热程度控制所述加热源的加热功率，以使得待加热物能够以较合适的加热过程被加热。When determining the heating frequency and heating phase corresponding to different parts of the object to be heated or different objects to be heated among the plurality of objects to be heated, since the purpose is not to heat the object to be heated, the controller 12 can control The heating source is heated with a lower preset heating power (for example, the total power is less than 100W) to save energy. Of course, the heating power can actually be set according to the characteristics of the object to be heated. In the case of high temperature, it will not The power can also be appropriately increased to cause denaturation of the substance; after determining the heating frequency and the heating phase, the controller 12 can control the heating power of the heating source according to the type of the object to be heated and the required heating degree, So that the object to be heated can be heated with a more suitable heating process.
以下将通过具体实施方式来详细描述本发明，但是本发明并不限制于此。The present invention will be described in detail below through specific embodiments, but the present invention is not limited thereto.
图2是根据本发明一种实施方式的四份化学试剂的加热示意图。如图2所示，在加热装置的加热室内放入四份化学试剂1、2、3、和4。四份化学试剂1、2、3、和4放入加热室后，在该实施方式中，采集四份化学试剂1、2、3和4的温度的装置可以是无线温度传感器，也可以是直接插入四份试剂中能检测温度的探针。Figure 2 is a schematic diagram of the heating of four chemical reagents according to one embodiment of the present invention. As shown in Figure 2, four parts of chemical reagents 1, 2, 3, and 4 were placed in the heating chamber of the heating device. After the four chemical reagents 1, 2, 3, and 4 are put into the heating chamber, in this embodiment, the device for collecting the temperature of the four chemical reagents 1, 2, 3, and 4 can be a wireless temperature sensor, or a direct Insert temperature-detecting probes into the four reagents.
首先，可以控制微波源以小功率(总功率小于100W)启动，然后进行热点扫描与分析。在这一过程中，需要通过改变微波源的频率、相位以确定处以下至少四个状态：在时间t内，1号化学试剂温升最大；在时间t内，2号化学试剂温升最大；在时间t内，3号化学试剂温升最大；在时间t内，4号化学试剂温升最大，分别将该四个状态下的微波源的频率和相位确定为四份化学试剂所对应的加热频率和加热相位。另外，可以根据寄存器容量的大小以及待加热物所要求的加热精度来选择是否记录在不同频率、相位组合下的各温升排列组合。First, the microwave source can be controlled to start with low power (total power less than 100W), and then the hot spot scanning and analysis can be performed. In this process, it is necessary to change the frequency and phase of the microwave source to determine at least the following four states: within the time t, the temperature rise of the chemical reagent No. 1 is the largest; within the time t, the temperature rise of the chemical reagent No. 2 is the largest; During the time t, the temperature rise of No. 3 chemical reagent is the largest; within the time t, the temperature rise of No. 4 chemical reagent is the largest, and the frequency and phase of the microwave source in the four states are respectively determined as the heating corresponding to the four chemical reagents frequency and heating phase. In addition, it can be selected according to the size of the register capacity and the heating accuracy required by the object to be heated whether to record the permutations and combinations of temperature rises under different frequency and phase combinations.
在本实施方式中，经过测试筛选，获得如图3所示的四份化学试剂分别对应的加热频率和加热相位，其中，在微波源频率为2420MHz，相位为0,0,0,0的A状态，1号化学试剂温升最大，则确定1号化学试剂所对应的加热频率和加热相位为2420MHz和0,0,0,0；在微波源频率为2470MHz，相位为0,60,180,0的B状态，2号化学试剂温升最大；在微波源频率为2450MHz，相位为-180,0,180,0的C状态，3号化学试剂温升最大；在微波源频率为2480MHz相位为-180,90,180,0的D状态，4号化学试剂温升最大。In this embodiment, after testing and screening, the heating frequencies and heating phases corresponding to the four chemical reagents as shown in Figure 3 are obtained, where the frequency of the microwave source is 2420MHz and the phase is 0,0,0,0 A state, the temperature rise of No. 1 chemical reagent is the largest, then determine the heating frequency and heating phase corresponding to No. 1 chemical reagent as 2420MHz and 0,0,0,0; when the microwave source frequency is 2470MHz, and the phase is 0,60,180,0 In state B, the temperature rise of chemical reagent No. 2 is the largest; in state C where the microwave source frequency is 2450MHz and the phase is -180,0,180,0, the temperature rise of chemical reagent No. 3 is the largest; when the microwave source frequency is 2480MHz, the phase is -180,90,180 , In the D state of 0, the temperature rise of chemical reagent No. 4 is the largest.
然后，按照待加热物需求的功率进行加热(通常为大功率)，为了快速加热，选择入射功率最高、反射功率最小的频率/相位点(通常为很多个)加热，当然也可以通过其它算法来获得合适的加热功率。在加热一段时间后，如果四份化学试剂之间的温差超过预设范围时，则将微波源的频率和相位切换为温度最低的化学试剂所对应的加热频率和加热相位。例如，1号试剂温度与其它三份化学试剂中某一个或多个的温度差超过预设范围，则将微波源的频率和相位切换为2420MHz和0,0,0,0，以此类推。等到四份化学试剂的温度达到预设温度后，可以控制微波源停止加热。Then, heat according to the power required by the object to be heated (usually high power). For rapid heating, select the frequency/phase point (usually many) with the highest incident power and the smallest reflected power for heating. Of course, other algorithms can also be used. Get the proper heating power. After heating for a period of time, if the temperature difference between the four chemical reagents exceeds a preset range, the frequency and phase of the microwave source are switched to the heating frequency and phase corresponding to the chemical reagent with the lowest temperature. For example, if the temperature difference between the No. 1 reagent and one or more of the other three chemical reagents exceeds the preset range, the frequency and phase of the microwave source are switched to 2420MHz and 0,0,0,0, and so on. After the temperatures of the four chemical reagents reach the preset temperature, the microwave source can be controlled to stop heating.
其中，针对不同的待加热物，温度差可以不同。对温度差要求相对严格的待加热物(如试剂)，通常将温度差的预设范围控制在2℃以内；对温度差要求不严格的待加热物(如牛奶)，可以将温度差的预设范围控制在5℃以内。Wherein, for different objects to be heated, the temperature difference may be different. For objects to be heated (such as reagents) that require relatively strict temperature differences, the preset range of temperature difference is usually controlled within 2°C; for objects to be heated that do not require strict temperature differences (such as milk), the preset temperature difference can be controlled Set the range to be controlled within 5°C.
图4是根据本发明提供的加热方法的流程图。如图4所示，在步骤S40处，根据待加热物所需功率控制加热源以起始功率开始加热；在步骤S41处，检测待加热物的不同部位或多个待加热物中的不同待加热物的温度；以及在步骤S42处，如果各温度之间的差值超过预设范围，则控制所述加热源按照确定的温度最低的待加热物的部位或待加热物所对应的加热频率和加热相位进行加热。上述加热方法能够在加热完成后将待加热物的各部分或不同待加热物的温度的差控制在较小范围内，从而能够实现均匀加热。Fig. 4 is a flow chart of the heating method provided by the present invention. As shown in Figure 4, at step S40, the heating source is controlled to start heating with the initial power according to the required power of the object to be heated; the temperature of the object to be heated; and at step S42, if the difference between the temperatures exceeds the preset range, then control the heating source according to the determined heating frequency corresponding to the part of the object to be heated with the lowest temperature or the object to be heated and heating phase for heating. The above heating method can control the temperature difference of each part of the object to be heated or different objects to be heated within a small range after the heating is completed, so as to realize uniform heating.
以下将参考图5详细描述本发明提供的加热方法，但是应该注意的是本发明并不限制于此。The heating method provided by the present invention will be described in detail below with reference to FIG. 5 , but it should be noted that the present invention is not limited thereto.
如图5所示，在步骤51处，可以控制微波源以小功率(总功率小于100W)启动，确定每个待加热物对应的加热频率和加热相位，例如，在预定周期内扫描覆盖所述待加热物所占区域的热点的温度；以及改变加热源的频率和相位，直至确定在所述预定周期内使所述待加热物的一部位或所述多个待加热物中的一待加热物的温升最大的加热源的频率和相位，将该频率和相位确定为所述待加热物的该部位或所述多个待加热物中的该待加热物对应的加热频率和加热相位。优选地，确定所述加热源开始加热时的频率和相位使得加热源的入射功率最高且反射功率最小As shown in Figure 5, at step 51, the microwave source can be controlled to start with a small power (total power less than 100W), and the corresponding heating frequency and heating phase of each object to be heated are determined, for example, scanning covers the the temperature of the hot spot in the area occupied by the object to be heated; and changing the frequency and phase of the heating source until it is determined that a portion of the object to be heated or one of the plurality of objects to be heated is heated within the predetermined period The frequency and phase of the heating source with the largest temperature rise of the object are determined as the heating frequency and phase corresponding to the part of the object to be heated or the object to be heated among the plurality of objects to be heated. Preferably, the frequency and phase at which the heating source starts heating are determined such that the incident power of the heating source is the highest and the reflected power is the smallest
在步骤52处，按照所需功率对待加热物进行加热；在步骤53处，检测待加热物的不同部位或多个待加热物中的不同待加热物的温度，判断各温度之间的插值超过预设范围。At step 52, the object to be heated is heated according to the required power; at step 53, the temperature of different parts of the object to be heated or different objects to be heated among multiple objects to be heated is detected, and it is judged that the interpolation value between the temperatures exceeds Default range.
在步骤54处，如果各温度之间的差值超过预设范围，则切换加热状态，例如控制所述加热源按照确定的温度最低的待加热物的部位或待加热物所对应的加热频率和加热相位进行加热。如果各温度之间的差值未超过预设范围，则转至步骤55处。At step 54, if the difference between the temperatures exceeds the preset range, then switch the heating state, for example, control the heating source according to the location of the object to be heated with the lowest temperature determined or the heating frequency corresponding to the object to be heated The heating phase is heated. If the difference between the temperatures does not exceed the preset range, go to step 55 .
在步骤55处，判断待加热物是否达到预设温度，如果达到预设温度则控制加热源停止加热；如果未达到预设温度，则继续对待加热物进行加热。At step 55, it is judged whether the object to be heated reaches the preset temperature, and if the preset temperature is reached, the heating source is controlled to stop heating; if the preset temperature is not reached, the object to be heated is continued to be heated.
有关加热方法的其它具体细节及益处与上述针对加热装置的细节及益处相同，于此不再赘述。Other specific details and benefits related to the heating method are the same as those described above for the heating device, and will not be repeated here.
