Cleaning of inner pot 111. The inner pot 111 is generally made of metal material and has a circular opening on the upper surface, and is used to contain materials to be heated, such as rice and soup. As shown in FIG. 2 , the pot body 110 may include a heating device 112 for heating the inner pot 111 . The cover body 120 is also basically in the shape of a rounded cuboid, and basically corresponds to the shape of the pot body 110 . The cover body 120 may be disposed on the upper side of the pot body 110 for covering the pot body 110 in a closed state. The cover body 120 can be in a closed position and an open position respectively relative to the pot body 110 . Preferably, the cover body 120 can switch between an open position and a closed position in a pivotal manner.
如图2和图3所示，内锅111具有双层锅壁区，双层锅壁区包括外层锅壁1111和内层锅壁1112，外层锅壁1111与内层锅壁1112之间形成有封闭空腔1113，封闭空腔1113中容纳有可以通过相变传热的介质。内层锅壁1112用于直接接触食物。根据加热装置112与内锅的相对位置，内锅可以分为受热部和非受热部，受热部为内锅111的面对烹饪器具100的加热装置112的部分，非受热部为内锅的其余部分，双层锅壁区至少部分地位于非受热部。本实施方式中的加热装置112为发热盘，在其他未示出的实施方式中，可以选用IH或其他加热装置。加热装置对受热部进行直接加热，热量可以通过封闭空腔1113中的介质均匀地传递给内层锅壁1112。As shown in Figure 2 and Figure 3, the inner pot 111 has a double-layer pot wall area, the double-layer pot wall area includes an outer layer pot wall 1111 and an inner layer pot wall 1112, between the outer layer pot wall 1111 and the inner layer pot wall 1112 A closed cavity 1113 is formed, and the closed cavity 1113 contains a medium capable of transferring heat through phase change. The inner pot wall 1112 is for direct contact with food. According to the relative position of the heating device 112 and the inner pot, the inner pot can be divided into a heated part and a non-heated part, the heated part is the part of the inner pot 111 facing the heating device 112 of the cooking utensil 100, and the non-heated part is the rest of the inner pot. Partially, the wall area of the double boiler is at least partially located in the non-heated part. The heating device 112 in this embodiment is a heating plate, and in other unshown embodiments, IH or other heating devices can be selected. The heating device directly heats the heat receiving part, and the heat can be evenly transferred to the inner pot wall 1112 through the medium in the closed cavity 1113 .
如图2和图3所示，煲体110内还设置有感温元件130，感温元件130固定地设置在内锅111的外表面上，具体地，是用焊接的方式固定地设置在非受热部的外层锅壁1111的外表面上，用于感测该处的温度。当然，在其他未示出的实施方式中，可以采用其他方式将感温元件固定在内锅的外侧。本实施方式中，感温元件130设置有外壳，可以采用导热系数较高的材料制成该外壳，比如，铜、铝等材料，以提高感温元件130的灵敏度及温度感测的准确性。在受热条件下，因为内锅111具有封闭空腔1113，且封闭空腔1113里存在均匀介质，感温元件130紧贴内锅111非受热部的外层锅壁1111的外表面，可以保证对温度采样的一致性和稳定性。在其他未示出的实施方式中，可以在外层锅壁上设置凸出部或凹陷部，并将感温元件设置在此处，以更好地感测温度。As shown in Fig. 2 and Fig. 3, a temperature-sensing element 130 is also arranged in the pot body 110, and the temperature-sensing element 130 is fixedly arranged on the outer surface of the inner pot 111, specifically, it is fixedly arranged on a non- The outer surface of the outer pot wall 1111 of the heat receiving part is used to sense the temperature there. Of course, in other implementations not shown, other ways can be used to fix the temperature sensing element on the outside of the inner pot. In this embodiment, the temperature-sensing element 130 is provided with a casing, which can be made of materials with high thermal conductivity, such as copper, aluminum, etc., to improve the sensitivity of the temperature-sensing element 130 and the accuracy of temperature sensing. Under the condition of heating, because the inner pot 111 has a closed cavity 1113, and there is a uniform medium in the closed cavity 1113, the temperature sensing element 130 is close to the outer surface of the outer wall 1111 of the non-heated part of the inner pot 111, which can ensure the Consistency and stability of temperature sampling. In other embodiments not shown, a protrusion or a depression may be provided on the outer wall of the pot, and a temperature sensing element may be provided there for better temperature sensing.
如图3所示，烹饪器具内还设置有印刷电路板132、第一线圈133(作为第一信号传输端的一种实施方式)和第二线圈134(作为第二信号传输端的一种实施方式)，其中，印刷电路板132上设置有信号处理装置。印刷电路板132上的信号处理装置通过导线135与感温元件130连接，以接收感温元件130测得的信号，并处理信号。第一线圈133通过导线135与印刷电路板132连接并获得印刷电路板132上的信号处理装置的信号，并通过无线的方式将信号传递给第二线圈134，第二线圈134再通过导线135将信号传递给烹饪器具100的控制部(未示出)。As shown in Figure 3, a printed circuit board 132, a first coil 133 (as an embodiment of the first signal transmission end) and a second coil 134 (as an embodiment of the second signal transmission end) are also arranged in the cooking appliance , wherein the printed circuit board 132 is provided with a signal processing device. The signal processing device on the printed circuit board 132 is connected to the temperature sensing element 130 through the wire 135 to receive the signal measured by the temperature sensing element 130 and process the signal. The first coil 133 is connected with the printed circuit board 132 by a wire 135 and obtains the signal of the signal processing device on the printed circuit board 132, and transmits the signal to the second coil 134 by a wireless mode, and the second coil 134 transmits the signal to the second coil 134 by a wire 135. The signal is transmitted to a control part (not shown) of the cooking appliance 100 .
需要说明的是，本文中，第一线圈133和第二线圈134中的至少一个可由导线缠绕而成，或者，第一线圈133和第二线圈134中的至少一个可以为印刷在印刷电路板上的印刷绕组。It should be noted that, herein, at least one of the first coil 133 and the second coil 134 can be formed by winding a wire, or at least one of the first coil 133 and the second coil 134 can be printed on a printed circuit board printed windings.
通过这种方式，感温元件130测得的信号通过无线的方式最终传递给控制部，较好地实现信号的采集和识别，也避免了复杂的连接关系，使得信号的传递更加简单有效。In this way, the signal measured by the temperature sensing element 130 is finally transmitted to the control unit in a wireless manner, which better realizes signal collection and identification, avoids complicated connection relationships, and makes signal transmission simpler and more effective.
本实施方式中，第一线圈133与第二线圈134形状大小相似，在竖直方向上彼此面对。现定义第一线圈133和第二线圈134中的一个在第一线圈133和第二线圈134中的另一个上的投影面积中，能够有效进行无线信号传输的那部分面积为有效投影面积，优选地，第一线圈133在第二线圈134上的有效投影面积或第二线圈134在第一线圈133上的有效投影面积小于800mm2，更优选为200-400mm2。第一线圈133与第二线圈134之间的距离D2最好小于30mm，优选为4-15mm。这样既可以保证无线信号的强度，又不占据太大空间。另外，考虑到印刷电路板132上的电子元件的耐温要求(一般不超过75℃)，因此在印刷电路板132与内锅111之间无隔热装置时，可以设置印刷电路板132与内锅111之间的距离D1为10-100mm，优选为15-40mm，当在印刷电路板132与内锅111之间设置隔热装置时，印刷电路板132与内锅111之间的距离可以设置为5-80mm，优选为10-30mm。In this embodiment, the first coil 133 and the second coil 134 are similar in shape and size, and face each other in the vertical direction. Now define the projected area of one of the first coil 133 and the second coil 134 on the other of the first coil 133 and the second coil 134, the area that can effectively carry out wireless signal transmission is the effective projected area, preferably Specifically, the effective projected area of the first coil 133 on the second coil 134 or the effective projected area of the second coil 134 on the first coil 133 is less than 800 mm2 , more preferably 200-400 mm2 . The distance D2 between the first coil 133 and the second coil 134 is preferably less than 30 mm, preferably 4-15 mm. This can not only ensure the strength of the wireless signal, but also does not occupy too much space. In addition, considering the temperature resistance requirements of the electronic components on the printed circuit board 132 (generally not more than 75 ° C), when there is no heat insulating device between the printed circuit board 132 and the inner pot 111, the printed circuit board 132 and the inner pot can be arranged. The distance D1 between the pots 111 is 10-100mm, preferably 15-40mm, when the heat insulation device is set between the printed circuit board 132 and the inner pot 111, the distance between the printed circuit board 132 and the inner pot 111 can be set 5-80mm, preferably 10-30mm.
如图3所示，本实施方式的烹饪器具100还包括固定盒150，固定盒150覆盖感温元件130、印刷电路板132和第一线圈133，固定盒150固定地与内锅111连接，不仅可以对感温元件130、印刷电路板132和第一线圈133起到固定和保护作用，同样可以作为用来移动内锅111的把手。As shown in Figure 3, the cooking utensil 100 of this embodiment also includes a fixed box 150, the fixed box 150 covers the temperature sensing element 130, the printed circuit board 132 and the first coil 133, the fixed box 150 is fixedly connected with the inner pot 111, not only It can fix and protect the temperature sensing element 130 , the printed circuit board 132 and the first coil 133 , and can also be used as a handle for moving the inner pot 111 .
本实施方式中，通过第二线圈134与第一线圈133之间的电磁感应对印刷电路板132进行供电，而在其他未示出的实施方式中，也可以在固定盒150内安装电池来对印刷电路板132供电。需要说明的是，当通过第二线圈134与第一线圈133之间的电磁感应对印刷电路板132供电时，从供电角度看，固定在煲体110内的作为第二信号传输端的第二线圈134为电功率发射装置，而与内锅111相连接(第一线圈133与感温元件130电连接，而感温元件130与内锅111固定连接)的作为第一信号传输端的第一线圈133则为电功率接收装置，印刷电路板132又通过导线135与电功率接收装置连接，这样，便实现了通过第二线圈134与第一线圈133之间的电磁感应对印刷电路板132供电，并且，印刷电路板132可以将电功率供应至感温元件130，从而使得感温元件130和印刷电路板132能够正常工作。可以看出，当采用电磁感应来对印刷电路板132供电时，测得的内锅的温度的信号的传递方向与对印刷电路板132的供电方向正好相反。In this embodiment, the printed circuit board 132 is powered by the electromagnetic induction between the second coil 134 and the first coil 133, and in other not-shown embodiments, a battery can also be installed in the fixed box 150 to power the printed circuit board 132. The printed circuit board 132 supplies power.

As an electric power receiving device, the printed circuit board 132 is connected to the electric power receiving device through a wire 135, so that the printed circuit board 132 is powered by the electromagnetic induction between the second coil 134 and the first coil 133, and the printed circuit board 132 The board 132 can supply electric power to the temperature sensing element 130 so that the temperature sensing element 130 and the printed circuit board 132 can work normally. It can be seen that when electromagnetic induction is used to supply power to the printed circuit board 132 , the transmission direction of the signal of the measured temperature of the inner pot is just opposite to the direction of power supply to the printed circuit board 132 .
通过将感温元件130直接固定在内锅111的非受热部的外层锅壁1111的外表面，可方便快捷地实现对温度的采集，且保证了采样的一致性和稳定性，另外，第一线圈133和第二线圈134采用无线的方式进行信号传输，避免了复杂结构，保证了信号传输的有效性。同时，设置了固定盒150等装置，使得温度感测装置能够更好地实现测温的作用。By directly fixing the temperature sensing element 130 on the outer surface of the outer wall 1111 of the non-heated part of the inner pot 111, the temperature can be collected conveniently and quickly, and the consistency and stability of the sampling can be guaranteed.

第七实施方式Seventh Embodiment
以下参照图10对本发明的第七实施方式进行说明。为了简化的目的，在描述第七实施方式时省去了与第一实施方式相同部分的描述。A seventh embodiment of the present invention will be described below with reference to FIG. 10 . For the purpose of simplification, description of the same parts as those of the first embodiment is omitted in describing the seventh embodiment.
在本实施方式中，烹饪器具包括第一线圈733(作为第一信号传输端的一种实施方式)和第二线圈734(作为第二信号传输端的一种实施方式)。其中，第二线圈734设置在盖体720内，并与第一线圈733间隔开。感温元件730紧贴外层锅壁，测得内锅的温度。当盖体盖合时，第一线圈733与第二线圈734之间的距离可以保证无线信号的顺利传输，实现对内锅温度的测量与传递。并且，由于当盖体720盖合煲体时，第二线圈734与第一线圈733之间的距离才能使得第二线圈734顺利接收无线信号，而当盖体打开时，由于第一线圈733和第二线圈734之间的距离太大，因此会使无线信号强度降低，第二线圈734无法顺利接收无线信号。因此本实施方式的温度感测装置还可以用于检测盖体720是否盖合。In this embodiment, the cooking appliance includes a first coil 733 (as an embodiment of the first signal transmission end) and a second coil 734 (as an embodiment of the second signal transmission end).

And, because when the cover body 720 closes the pot body, the distance between the second coil 734 and the first coil 733 can make the second coil 734 receive the wireless signal smoothly, and when the cover body is opened, due to the first coil 733 and the first coil 733 The distance between the second coils 734 is too large, so the strength of the wireless signal will be reduced, and the second coil 734 cannot receive the wireless signal smoothly. Therefore, the temperature sensing device in this embodiment can also be used to detect whether the cover 720 is closed.
第八实施方式Eighth embodiment
图11示出了本发明的第八实施方式。为了简化的目的，在描述第八实施方式时省去了与第一实施方式相同部分的描述。Fig. 11 shows an eighth embodiment of the present invention. For the purpose of simplification, description of the same parts as those of the first embodiment is omitted in describing the eighth embodiment.

The temperature sensing element 830 is arranged on the outer surface of the outer pot wall 8111 at the upper part of the side wall, and senses the temperature there sensitively and accurately. At the same time, because the temperature measuring place is a double-layer pot wall structure with a small gap, the volume of the closed cavity between the outer pot wall 8111 and the inner pot wall 8112 of the inner pot is small, so the temperature sensing element 830 is used to sense the temperature here. The temperature of the inner pot can make the control part more effectively control the heating of the heating part, and can timely eliminate the danger caused by the excessive pressure of the closed cavity.
