Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. Below by reference to the attached drawings The described embodiments are illustrative and are not intended to limit the invention.

A temperature measuring assembly 10 for a microwave device 1 according to an embodiment of the present invention will be described in detail below with reference to Figs. Here, the microwave device 1 may be an electric appliance that heats an article (for example, food) using microwaves, such as a microwave oven or a microwave oven. In order to meet the user's use requirements, the temperature measuring component 10 can be used to detect the temperature of the food in the microwave device 1. Before the microwave device 1 heats the food, the end of the temperature measuring component 10 for detecting the temperature can be placed in the food or food. Nearby, when the microwave device 1 is heating the food, one end of the detection temperature of the detection assembly 10 can be closer to the food, so that the temperature detected by the detection assembly 10 can be closer to the true temperature of the food.

As shown in FIGS. 1 to 6, a temperature measuring assembly 10 for a microwave device 1 according to an embodiment of the present invention includes a wire 11, a first housing 12, a second housing 13, and a shielding layer for shielding interference signals. 14.

Specifically, the first housing 12 has a first receiving cavity 121. The first receiving cavity 121 is provided with a temperature sensing member 122. The first end 11a of the wire 11 extends into the first receiving cavity 121 and is associated with the temperature sensing component. The second housing 13 has a second receiving cavity 131, and the wire 11 is adapted to be electrically connected to the second housing 13. The temperature sensing member 122 is disposed in the first accommodating cavity 121, and is connected to the wire 11 of the first end 11a extending into the first accommodating cavity 121, and the second end 11b of the wire 11 is electrically connected to the second casing 13, thereby being The signal detected by the temperature sensing member 122 is derived, thereby realizing the transmission of the signal. Here, the connection form of the wire 11 and the second casing 13 is not limited, and the wire 11 may be directly connected to the second casing 13 or may be connected to the second casing 13 through the intermediate connection.

The wire 11 is wrapped with a shielding layer 14 on at least a portion between the first housing 12 and the second housing 13. That is, on the wire 11 between the first casing 12 and the second casing 13, the shielding layer 14 may be wrapped around a portion of the outer peripheral wall of the segment of the wire 11, or may be wrapped around the wire 11 On the outer peripheral wall. Thereby, the interference generated by the microwave field on the wire 11 can be shielded, and the stability and accuracy of the signal transmission of the wire 11 can be improved. At the same time, it should be noted that the shielding layer 14 can be grounded to facilitate the timely induction of the induced current generated by the microwave field, thereby avoiding the skin effect and the eddy current effect caused by the induced current, thereby increasing the temperature of the temperature measuring component 10 itself. The temperature measurement causes interference, so that the accurate temperature measurement of the temperature measuring component 10 in the microwave environment can be realized, and the purpose of detecting the temperature of the food under the microwave field can be achieved.

Under strong electromagnetic fields, when measured with conventional temperature sensors (such as thermocouples, thermal resistors, etc.), measuring probes and wires made of metal materials generate induced currents under high-frequency electromagnetic fields, and their own temperature due to skin effect and eddy current effect. Elevated, causing serious interference to temperature measurement, causing large errors in temperature indication or inability to perform stable temperature measurement, and also causing great harm to microwave equipment. Although the infrared sensor can be used in the microwave environment, it can only monitor the surface temperature of the food, and the measurement accuracy is greatly affected by the environment. Optical fiber sensors, such as semiconductor, fiber grating, and FP cavity, have not been widely used due to their high cost.

The temperature measuring assembly 10 for the microwave device 1 according to an embodiment of the present invention can shield the microwave by providing a shielding layer 14 on at least a portion of the wire 11 between the first housing 12 and the second housing 13. The interference signal generated by the field on the wire 11 improves the stability and accuracy of the signal transmission of the wire 11, so that the temperature detected by the temperature sensing member 122 can be detected. The degree is closer to the real temperature, thereby improving the anti-electromagnetic interference capability of the temperature measuring component 10.

As shown in FIG. 1 to FIG. 6, according to an embodiment of the present invention, the shielding layer 14 may be a conductive shielding layer made of an electrically conductive material. For example, the shielding layer 14 may be a metal shielding layer, thereby effectively shielding. The interference caused by the microwave field to the wire 11. Further, the temperature measuring assembly 10 may further include a protective cover 15 wrapped around the outer peripheral wall of the shielding layer 14, thereby effectively protecting the shielding layer 14 and preventing the shielding layer 14 from being ignited during use. Thereby, the safety of the temperature measuring assembly 10 can be improved, and the service life of the temperature measuring assembly 10 can be extended.

Alternatively, as shown in FIGS. 1 and 3, the inner wall of the protective cover 15 is in close contact with the outer wall of the shield layer 14. Optionally, the inner diameter of the protective sleeve 15 is the same as the outer diameter of the shielding layer 14. It should be noted that the protective cover 15 may be a silicone protective cover made of a silicone material. Here, the silicone material is commonly known as silicone rubber, which is non-toxic and tasteless, chemically stable, and has good insulation properties, and is widely used in electronic appliances. Thereby, the shielding layer 14 can be effectively protected from the microwaves from entering the gap between the protective cover 15 and the shielding layer 14, so that the sparking phenomenon of the shielding layer 14 during use can be avoided.

Alternatively, the length of the shielding layer 14 may be greater than the length of the protective cover 15. Therefore, the shielding layer 14 can effectively shield the interference signal generated by the microwave field on the wire 11 and improve the stability and accuracy of the signal transmission of the wire 11. The protective cover 15 can effectively protect the shielding layer 14 and prevent the shielding layer 14 from being used. The phenomenon of sparking occurs in the process, thereby effectively improving the safety and temperature measurement accuracy of the temperature measuring assembly 10. Further, both ends of the shielding layer 14 extend to the outside of the protective cover 15, whereby both ends of the shielding layer 14 can respectively protrude into the first housing 12 and the second housing 13, further shielding the generation of the wires 11. Interference signal.

As shown in FIG. 1 to FIG. 3, in order to facilitate the connection of the wire 11 to the temperature sensing member 122, the first receiving cavity 121 may have a first opening 1211, and the first end 11a of the wire 11 may extend from the first opening 1211 to the first The chamber 121 is accommodated. The temperature sensing member 122 is disposed away from the first opening 1211 for measuring a temperature signal. The shield layer 14 extends into the first housing 12, whereby the shield layer 14 can effectively protect the wires 11 at the first opening 1211, thereby effectively preventing the microwave field from interfering with temperature measurement. For example, as shown in FIG. 2, one end of the first receiving cavity 121 is open to form a first opening 1211, and the other end is closed. The temperature sensing member 122 is disposed at the closed end of the first receiving cavity 121, and the wire 11 can be from the first opening. The first receiving cavity 121 is inserted into the first receiving cavity 121 and connected to the temperature sensing member 122. One end of the shielding layer 14 can extend from the first opening 1211 into the first receiving cavity 121.

It should be noted that the temperature sensing member 122 can be a thermistor or a temperature sensing chip, and both ends of the temperature sensing member 122 are respectively connected to the wire 11 through the fixed terminal 123. As shown in FIG. 4, in order to prevent the temperature sensing member 122 from shaking in the first accommodating cavity 121, the first casing 12 is filled with the thermal grease 44, which not only improves the response time and sensitivity of the temperature sensing member 122, but also serves as insulation. And simplify the role of the processing technology. It should be noted that the thermal grease 44 is a high thermal conductive insulating silicone material, which has excellent electrical insulation and excellent thermal conductivity, and is widely applied to various electronic products and heating elements in electrical equipment ( The contact surface between the power tube, the thyristor, the electrothermal stack, and the heat dissipation device (heat sink, heat sink, housing, etc.) functions as a heat transfer medium and is resistant to moisture, dust, corrosion, and shock.

The temperature measuring assembly 10 can also include a first annular fastener 16 that is disposed within the first receiving cavity 121 and within the first annular fastener 16 as shown in FIGS. 2 and 5. The peripheral wall is in close contact with the outer peripheral wall of the shield layer 14, and the outer peripheral wall of the first annular fastener 16 is in close contact with the inner wall of the first accommodating chamber 121. In other words, the inner diameter of the first annular fastener 16 is smaller than or equal to the outer diameter of the shielding layer 14 , and the outer diameter of the first annular fastener 16 is greater than or equal to the inner diameter of the first receiving cavity 121 . Therefore, it is possible to effectively prevent a gap from occurring between the inner peripheral wall of the first annular fastener 16 and the shield layer 14 and prevent a gap between the outer peripheral wall of the first annular fastener 16 and the inner peripheral wall of the first receiving cavity 121. Thereby, the microwave can be effectively prevented from entering the first casing 12, thereby improving the accuracy and stability of the signal transmission of the temperature measuring component 10. Alternatively, the first loop fastener 16 may be made of a metallic material, ie the first loop fastener 16 may be formed as an annular metal fastener. Thereby, the structural strength of the first loop fastener 16 can be improved, and the shield layer 14 can be firmly attached to the wire 11.

Further, the edge of the first opening 1211 of the first accommodating cavity 121 is contracted toward the first opening 1211 to form a first venting portion 1212, as shown in FIGS. 2 and 5. In other words, from the closed end of the first accommodating chamber 121 to the open end direction of the first accommodating chamber 121, the cross-sectional area of the end portion of the first accommodating chamber 121 close to the first opening 1211 is gradually reduced. Thereby, the first loop fastener 16 can be prevented from slipping toward the open end during use, affecting the accuracy of the temperature measurement.

As shown in FIG. 1 , FIG. 3 and FIG. 6 , the second receiving cavity 131 may have a second opening 1311 , and the shielding layer 14 extends into the second housing 13 , whereby the shielding layer 14 can effectively protect the second opening 1311 . The wire 11 at the location can effectively prevent the microwave field from interfering with the temperature measurement. For example, as shown in FIG. 6, the other end of the shield layer 14 may extend from the second opening 1311 into the second receiving cavity 131.

The temperature measuring assembly 10 can also include a second annular fastener 17. The second annular fastener 17 is disposed in the second receiving cavity 131, and the inner peripheral wall of the second annular fastener 17 is in close contact with the outer peripheral wall of the shielding layer 14, and the outer peripheral wall of the second annular fastener 17 is The inner walls of the two receiving chambers 131 are in close contact. In other words, the second annular fastener 17 is placed in the second receiving cavity 131, the inner diameter of the second annular fastener 17 is smaller than or equal to the outer diameter of the shielding layer 14, and the outer diameter of the second annular fastener 17 is larger than It is equal to the inner diameter of the second accommodating cavity 131. Thereby, a gap can be effectively prevented from occurring between the inner peripheral wall of the second annular fastener 17 and the shield layer 14, and a gap between the outer peripheral wall of the second annular fastener 17 and the inner peripheral wall of the second receiving cavity 131 can be prevented. Thereby, the microwave can be effectively prevented from entering the second casing 13, thereby improving the accuracy and stability of the signal transmission of the temperature measuring component 10. Alternatively, the second loop fastener 17 may be made of a metallic material, ie the second loop fastener 17 may be formed as an annular metal fastener. Thereby, the structural strength of the second loop fastener 17 can be increased, and the shield layer 14 can be firmly attached to the wire 11.

In one example of the present invention, the wires 11 in the temperature measuring assembly 10 may be two, and the second ends 11b of the two wires 11 extend into the second receiving cavity 131 and are connected to the second housing 13 . Used to transmit signals. It can be understood that the two wires 11 of the temperature measuring component 10 can be used as signal wires for transmitting signals, one of the two wires 11 is connected to the high voltage end, and the other is connected to the low voltage end, and the shielding layer 14 Wrapped in the outer peripheral wall of the two wires 11 can be used At the grounding time, the induced current generated under the microwave field is guided away, and the induced current is prevented from interfering with the transmission of the temperature signal of the wire 11 to the temperature measuring component 10. It should be noted that the temperature sensing component converts the detected temperature signal into an electrical signal (such as voltage or current information) and transmits it to the controller of the microwave device through the wire, and the induced current generated under the microwave field is easy to be on the wire. The electrical signal corresponding to the temperature signal causes interference, which may easily cause the phenomenon that the temperature information detected by the temperature measuring component is inconsistent with the temperature information transmitted to the controller, thereby affecting the accuracy of the detection result of the temperature measuring component. By encapsulating the shielding layer 14 on the two wires 11, the induced current generated under the microwave field can be effectively guided away, and the induced current is prevented from interfering with the detection accuracy of the temperature of the temperature measuring component 10, so that the temperature measuring component 10 can be detected. The temperature is closer to the true temperature of the food.

For example, as shown in FIG. 1 , FIG. 5 and FIG. 6 , the first ends 11 a of the two wires 11 extend into the first receiving cavity 121 of the first housing 12 and are connected to the temperature sensing member 122 . The second end 11b of the second housing 13 extends into the second receiving cavity 131 of the second housing 13 and is connected to the inner wall of the second receiving cavity 131, and the two wires 11 are externally wrapped with the shielding layer 14. It extends to the inside of the first housing 12 and the second housing 13. A portion of the shielding layer 14 located in the first housing 12 is fixed in the first receiving cavity 121 by the first annular fastener 16, and a portion of the shielding layer 14 located in the second housing 13 is fixed by the second annular fastener 17. In the second accommodating chamber 131. At the same time, the shield layer 14 is grounded. Here, the shielding layer 14, the first annular fastener 16, the second annular fastener 17, the first housing 12, and the second housing 13 may each be made of a metal material when an induced current is generated under the microwave field. The shielding layer 14 can not only guide the induced current generated on the wire 11, but also can guide the induced current generated on the first casing 12 and the second casing 13 to prevent the induced current from causing the first casing 12, The temperature of the second casing 13 rises to interfere with the temperature measurement, effectively reducing the interference of the induced current generated under the microwave field to the transmission of the temperature signal, and ensuring the accuracy of the signal transmitted by the wire 11.

In another example of the present invention, the wires 11 are two, and the second end 11b of one of the wires 11 extends into the second receiving cavity 131, and the second end 11b of the other wire 11 and the shielding layer 14 One end is electrically connected, and the other end of the shielding layer 14 is connected to the second housing 13. At this time, the shielding layer 14 can be used as a wire to conduct a signal with temperature information. Thereby, the length of the wire 11 can be reduced, the production material can be saved, and the production cost can be reduced. Further, as shown in FIG. 6, the other end of the shielding layer 14 extends into the second receiving cavity 131 and is connected to the inner wall of the second receiving cavity 131, thereby facilitating the second end 11b of the wire 11 and the second receiving cavity. The inner wall of 131 is connected. Thereby, the shield layer 14 can effectively protect the wires 11 located at the second opening 1311, so that the microwave field can be effectively prevented from interfering with the temperature measurement.

As shown in FIG. 1 and FIG. 3, in order to facilitate the user to take the temperature measuring component 10, the temperature measuring component 10 can be provided with a handle 18, and the handle 18 can be two, one of the handles 18 is disposed on the first housing 12. The end of the first housing 12 adjacent to the first opening 1211 extends into the interior of the handle 18. The shielding layer 14 and one end of the protective layer 15 pass through the handle 18 and extend into the first receiving cavity 121 through the first opening 1211. Another handle 18 is disposed on the second housing 13, and an end of the second housing 13 adjacent to the second opening 1311 projects into the interior of the handle 18, and the shielding layer 14 and the other end of the protective layer 15 are worn. After the handle 18 is passed, the second opening 1311 extends into the second receiving cavity 131. Alternatively, the handle 18 can be a silicone handle made of an insulating silicone material, whereby the handle 18 can have better insulation and thermal insulation properties, thereby preventing heat in the cooking chamber 22 from affecting the temperature measuring assembly 10. The detection of the temperature of the food allows the temperature detected by the temperature measuring assembly 10 to be closer to the temperature of the food.
