电加热锅具中，为了防止锅具干烧，均增加了自动控温功能。如用来蒸米饭的电饭煲，则是在锅底附近增加热传感器，当锅内有水时，锅底温度一般在100-104摄氏度左右；而当锅底的没有水时，温度会急剧升高，当超过预定温度时，一般为105摄氏度时则停止加热。In electric heating cookware, in order to prevent the cookware from drying out, an automatic temperature control function is added. For example, a rice cooker used to steam rice adds a heat sensor near the bottom of the pot.

具体实施方式Detailed ways

下面结合附图和实施例对本发明做进一步的说明。The present invention will be further described below with reference to the accompanying drawings and embodiments.

本发明的实现是依据对蒸汽的监测实现的。The realization of the present invention is realized according to the monitoring of steam.

因此本发明中的蒸汽参数检测传感器是一个概念，即是对通过蒸汽参数能进行检测的传感器的总概念，其包括但不限于蒸汽温度传感器或蒸汽流量传感器。本发明现以蒸汽温度以及蒸汽的流量对本发明进行进一步的说明。Therefore, the steam parameter detection sensor in the present invention is a concept, that is, a general concept of sensors that can detect steam parameters, including but not limited to a steam temperature sensor or a steam flow sensor. The present invention will now be further described with reference to the steam temperature and the flow rate of the steam.

本发明中的锅具包括但不限于是电饭煲。为了说明方便，下述内容以电饭煲为例进行说明。The cookware in the present invention includes, but is not limited to, a rice cooker. For the convenience of description, the following content will be described by taking a rice cooker as an example.

实施例1Example 1

本实施例为以蒸汽温度进行检测，如图1所示，在锅体1上设置有和锅盖11，在锅盖11上设置有蒸汽导流通道12(蒸汽导流通道也可以根据需要设置在锅体内其它位置)，在所述的蒸汽导流通道内设置有一个蒸汽温度传感器13，当蒸汽温度传感器当监测的蒸汽温度低于预定值时，输出控制信号。In this embodiment, the temperature of the steam is detected. As shown in FIG. 1 , apot body 1 is provided with apot cover 11 , and asteam guide channel 12 is provided on the pot cover 11 (the steam guide channel can also be provided as required). In other positions in the pot body), asteam temperature sensor 13 is arranged in the steam guiding channel, and when the steam temperature sensor monitored is lower than a predetermined value, it outputs a control signal.

本实施例的原理是：当锅体内的水烧开后，在保持加热的状态下，蒸汽会始终保持一定的量，这时，蒸汽导流通道12蒸汽温度传感器也就能检测出蒸汽的温度。而随着锅体的持续的加热，当锅体内的水逐渐减少时，蒸汽的量会越来越小，而导致蒸汽导流通道12蒸汽温度传感器检测的温度也会逐渐降低。当低于预定值时，即可以判定锅已处于干烧状态，停止加热即可。The principle of this embodiment is: when the water in the pot is boiled, the steam will always keep a certain amount in the heating state, and at this time, the steam temperature sensor of thesteam guide channel 12 can also detect the temperature of the steam . With the continuous heating of the pot body, when the water in the pot body gradually decreases, the amount of steam will become smaller and smaller, and the temperature detected by the steam temperature sensor of thesteam guide channel 12 will also gradually decrease. When it is lower than the predetermined value, it can be determined that the pot has been in a dry burning state, and the heating can be stopped.

图7为测试结果图，其是在导流通道连续设置5个温度传感器，每两个相距10毫米进行测试的结果。从图中可以看出，当锅具处于干烧状态时，5个温度传感器所检测的温度均呈现断崖式下跌。由此可证明，本实施例的方法是有效的。FIG. 7 is a test result graph, which is the result of testing five temperature sensors continuously arranged in the diversion channel, and each two is 10 mm apart. It can be seen from the figure that when the pot is in a dry burning state, the temperatures detected by the five temperature sensors all show a cliff-like drop. Therefore, it can be proved that the method of this embodiment is effective.

实施例2Example 2

本实施例为以蒸汽温度进行检测，如图2所示，在锅体1上设置有和锅盖11，在锅盖11上设置有蒸汽导流通道12，在所述的蒸汽导流通道内设置有三个蒸汽温度传感器13，这样当蒸汽导流通道内最后一个蒸汽温度传感器检测不到蒸汽、而蒸汽导流通道内前两个可以检测到蒸汽温度时，输出控制信号。或者，当蒸汽导流通道内后两个之一蒸汽温度传感器检测不到蒸汽，而蒸汽导流通道内第一个可以检测到蒸汽温度时，输出控制信号。In this embodiment, the temperature is detected by steam. As shown in FIG. 2 , apot body 1 is provided with apot cover 11 , and asteam guide channel 12 is provided on thepot cover 11 . In the steam guide channel Threesteam temperature sensors 13 are provided, so that when the last steam temperature sensor in the steam guide channel cannot detect steam, but the first two steam temperature sensors in the steam guide channel can detect the steam temperature, a control signal is output. Or, when one of the last two steam temperature sensors in the steam guiding channel cannot detect the steam, but the first one in the steam guiding channel can detect the steam temperature, a control signal is output.

本实施例的原理与实施例1类似：当锅体内的水烧开后，在保持加热的状态下，蒸汽会始终保持一定的量，这时，蒸汽导流通道12中的三个蒸汽温度传感器均能检测出蒸汽的温度。而随着锅体的持续的加热，当锅体内的水逐渐减少时，蒸汽的量会越来越小，而导致蒸汽导流通道12蒸汽温度传感器检测的温度也会逐渐降低。这样，当前边的一个或两个能检测出蒸汽温度而后边的一个或两个检测不出蒸汽温度时，则可以判断锅具已处于干烧状态，停止加热即可。The principle of this embodiment is similar to that of Embodiment 1: when the water in the pot is boiled, the steam will always maintain a certain amount in a heated state. At this time, the three steam temperature sensors in thesteam guide channel 12 The temperature of the steam can be detected. With the continuous heating of the pot body, when the water in the pot body gradually decreases, the amount of steam will become smaller and smaller, and the temperature detected by the steam temperature sensor of thesteam guide channel 12 will also gradually decrease. In this way, when one or two of the front side can detect the steam temperature and one or two of the rear side can not detect the steam temperature, it can be judged that the pot is in a dry burning state, and the heating can be stopped.

这种结构，可以防止锅具内的食物溢出而导致蒸汽导流通道堵塞而造成的误判。This structure can prevent misjudgment caused by the clogging of the steam guiding channel caused by the overflow of food in the pot.

当温度传感器为多个时，其间距可以按从小到达逐渐增加。例如，第一个与第二传感器的间距为10毫米；第二个与第三传感器的间距为20毫米；第三个与第四传感器的间距为40毫米；这样，可以防止较近的两个传感器检测的值较为接近，而导致误判。When there are multiple temperature sensors, the distance between them can be gradually increased from small to small. For example, the distance between the first and the second sensor is 10mm; the distance between the second and the third sensor is 20mm; the distance between the third and the fourth sensor is 40mm; The value detected by the sensor is relatively close, resulting in a misjudgment.

实施例3Example 3

本实施例为以蒸汽电阻进行检测，如图3所示，在锅体1上设置有和锅盖11，在锅盖11上设置有蒸汽导流通道12，在所述的蒸汽导流通道内设置有蒸汽电阻传感器14—其为间隔预定距离设置的两个金属探针。两个探针的间距为0.1-2毫米。In this embodiment, steam resistance is used for detection. As shown in FIG. 3 , apot body 1 is provided with apot cover 11 , and asteam guide channel 12 is provided on thepot cover 11 . In the steam guide channel Avapor resistance sensor 14 is provided, which are two metal probes arranged at a predetermined distance. The spacing between the two probes is 0.1-2 mm.

本实施例的原理与实施例1类似：当锅体内的水烧开后，在保持加热的状态下，蒸汽会始终保持一定的量，这时，蒸汽导流通道12中湿度足够大，这时两个探针之间的电阻会比较低。而随着锅体的持续的加热，当锅体内的水逐渐减少时，蒸汽的量会越来越小，这时两个探针之间的电阻会越来越高，当电阻高到一定值时则可以判断锅具已处于干烧状态，停止加热即可。The principle of this embodiment is similar to that of Embodiment 1: when the water in the pot is boiled, the steam will always maintain a certain amount in a heated state. At this time, the humidity in thesteam guide channel 12 is large enough. The resistance between the two probes will be lower. With the continuous heating of the pot body, when the water in the pot body gradually decreases, the amount of steam will become smaller and smaller. At this time, the resistance between the two probes will become higher and higher. When the resistance reaches a certain value At this time, it can be judged that the pot is in a dry burning state, and the heating can be stopped.

实施例4Example 4

本实施例为对蒸汽流量的检测This embodiment is for the detection of steam flow

本实施例为以蒸汽温度进行检测，如图4和图5所示，在锅盖11上设置有蒸汽导流通道12，在所述的蒸汽导流通道内设置有一个蒸汽流量传感器15，若蒸汽流量当监测的蒸汽流量低于预定值时，输出控制信号。In this embodiment, the temperature of the steam is detected. As shown in FIG. 4 and FIG. 5 , asteam guide channel 12 is provided on thelid 11, and asteam flow sensor 15 is arranged in the steam guide channel. Steam flow When the monitored steam flow is lower than a predetermined value, a control signal is output.

如图5所示，蒸汽流量传感器15设置有锅盖上方，与蒸汽导流通道12对应设置。蒸汽流量传感器15包括上盖151和下盖152，上、下盖相互扣合，在下盖向上设置有下导流通道153；在上盖上对应下导流通道153设置有叶轮室；叶轮室向下设置有上导流通道154；当上下盖扣合后，下导流通道153、上导流通道154两个导流通道连通。在上导流通道154上段设置有导流通孔156，使蒸汽从导流通道12通过下导流通道15、上导流通道154，然后从导流通孔156中喷出；在上导流通道154旋转设置有一个叶轮155，叶轮的叶片与导流通孔156对应设置。在叶轮室下部设置有出气孔157以及在上盖一侧设置有出气孔158；As shown in FIG. 5 , thesteam flow sensor 15 is disposed above the pot cover, and is disposed corresponding to thesteam guiding channel 12 . Thesteam flow sensor 15 includes anupper cover 151 and alower cover 152, the upper and lower covers are fastened to each other, and alower guide channel 153 is arranged upward on the lower cover; an impeller chamber is arranged on the upper cover corresponding to thelower guide channel 153; Anupper guide channel 154 is provided at the bottom; when the upper and lower covers are fastened together, thelower guide channel 153 and theupper guide channel 154 are communicated with each other. Aguide flow hole 156 is provided in the upper section of theupper guide channel 154, so that the steam from theguide channel 12 passes through thelower guide channel 15 and theupper guide channel 154, and then is ejected from theguide flow hole 156; in theupper guide channel 154 Animpeller 155 is rotatably arranged, and the blades of the impeller are arranged corresponding to the guide flow holes 156 . Avent hole 157 is provided at the lower part of the impeller chamber and avent hole 158 is provided on one side of the upper cover;

这样，当有蒸汽时，叶轮在蒸汽的作用下，会旋转，而当蒸汽减少时，叶轮的转速就会下降，这样只需通过转速监测装置即可以对其进行判定。即当转速降至预定值时则可以判断锅具已处于干烧状态，停止加热即可。In this way, when there is steam, the impeller will rotate under the action of the steam, and when the steam decreases, the speed of the impeller will decrease, so that it can be judged only by the speed monitoring device. That is, when the rotation speed drops to a predetermined value, it can be judged that the cookware is in a dry-burning state, and the heating can be stopped.

转速检测装置，可以根据需要选择。图5中，是在叶轮155的其中一个叶片上设置铁磁物质159；而在其一侧设置磁感应检测元件160，如霍尔元件即可，这样叶轮每旋转一圈，就会被磁感应检测元件检测到一次，这样，记录旋转一圈所需的时间即可计算其转速。而比较每次的转速，即可以得知现在锅具的蒸汽量。在下盖一侧设置有触点161，用于与锅盖上对应位置的触点接触，以传递转速信号。The rotational speed detection device can be selected according to the needs. In Fig. 5, aferromagnetic substance 159 is arranged on one of the blades of theimpeller 155; and a magneticinduction detection element 160 is arranged on one side of the impeller, such as a Hall element, so that every time the impeller rotates, it will be detected by the magnetic induction detection element. It is detected once so that its rotational speed can be calculated by recording the time it takes to make one revolution. By comparing the speed of each time, you can know the current steam volume of the pot. Acontact 161 is provided on one side of the lower cover, which is used for contacting with a contact at a corresponding position on the pot cover to transmit a rotational speed signal.

实施例5Example 5

对于实施例4的变形，还可以制备专门的防干烧检测装置，如图6所示。在锅盖11上设置有蒸汽导流通道12，在蒸汽导流通道12的出口处设置有防干烧报警装置，防干烧报警装置包括一底座，底座可以放在锅盖上，底座上设置有竖起设置有旋转叶轮；这样，蒸汽导流通道12上的叶轮在蒸汽作用下会旋转，而在底座内设置有转速检测装置。与实施例类似的，只需监测叶轮的转速即可防止干烧。For the modification of Example 4, a special anti-dry-burn detection device can also be prepared, as shown in FIG. 6 . Asteam diversion channel 12 is provided on thelid 11, and an anti-dry burning alarm device is provided at the outlet of thesteam diversion channel 12. The anti-dry burning alarm device includes a base, the base can be placed on the lid, and the base is provided with A rotating impeller is erected; in this way, the impeller on thesteam guiding channel 12 will rotate under the action of steam, and a rotational speed detection device is arranged in the base. Similar to the embodiment, dry burning can be prevented by simply monitoring the rotational speed of the impeller.

实施例6Example 6

本实施例为实施例1的变形。如图8所示，在锅体1上设置有和锅盖11，在锅盖11上设置有蒸汽导流通道12，在所述的蒸汽导流通道内设置有一个蒸汽温度传感器13，与实施例1不同的是，所述的当蒸汽温度传感器设置在蒸汽出口一侧0.5-5厘米左右。This embodiment is a modification ofEmbodiment 1. As shown in FIG. 8 , apot body 1 is provided with apot cover 11, asteam guide channel 12 is provided on thepot cover 11, and asteam temperature sensor 13 is arranged in the steam guide channel. The difference of Example 1 is that the steam temperature sensor is set at about 0.5-5 cm on the side of the steam outlet.

这样，当蒸汽量较足时，蒸汽温度传感器13虽然偏离蒸汽一段距离，但也能感受到其温度，并不影响其对温度的检测。而当锅内的水快要即将烧完时，其蒸汽量会明显下降，由于蒸汽温度传感器13偏离蒸汽一段距离，因此其会较早的检测到温度的降低，以便较早的对“烧干锅”现象进行及时干预。In this way, when the amount of steam is sufficient, although thesteam temperature sensor 13 deviates from the steam for a certain distance, it can still sense its temperature and does not affect its detection of the temperature. When the water in the pot is about to burn out, the amount of steam will drop significantly. Since thesteam temperature sensor 13 deviates from the steam for a certain distance, it will detect the decrease in temperature earlier, so that the “dry pot” can be detected earlier. ” to intervene in a timely manner.
