[0003] In order to ensure the cooking effect, the equipment usually needs to detect the temperature of the pot body in real time. At present, infrared sensors are generally used to measure the temperature of the pot body. Specifically, the infrared sensor usually collects infrared signals passing through the heating device to obtain the temperature data of the pot body.

For example, when the heating device is a heating coil, the spacing between the wires on the coil is small. Therefore, the heating coil can easily block the infrared sensor's viewing angle, thereby reducing the accuracy of the temperature measurement collected by the infrared sensor. Utility Model Content

Therefore, it should not be understood as limiting the scope of protection of this embodiment.
[0037] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a cooking device, including a pot body 1; a heating device 2, which is arranged on the outside of the pot body 1 and is used to generate an electromagnetic field to heat the pot body 1; a temperature measuring component 3, which includes an infrared sensor 31 and a guide part 32, the infrared sensor 31 is arranged on a side of the heating device 2 away from the pot body 1, one end of the guide part 32 is connected to the infrared sensor 31, and the other end of the guide part 32 is connected to the infrared wave radiated by the pot body 1.
[0038] The heating device 2 can be any device capable of generating an electromagnetic field to heat the pot body 1. Specifically, the heating device 2 can be a heating coil. There are various ways in which the heating device 2 can be disposed outside the pot body 1. For example, the heating device 2 can be disposed outside the pot body 1, or the heating device 2 and the pot body 1 can be integrally assembled so that the heating device 2 can heat the pot body 1 at any time. Alternatively, the heating device 2 and the pot body 1 can be disposed separately, so that the heating device 2 can only heat the pot body 1 when the pot body 1 is placed on the heating device 2.
[0039] In the cooking device provided by the embodiment of the present invention, the temperature measuring component 3 includes an infrared sensor 31 and a guide part 32, wherein one end of the guide part 32 is connected to the infrared sensor 31, and the other end of the guide part 32 is connected to the infrared wave radiated by the pot body 1, so that the guide part 32 can guide the infrared wave radiated by the pot body 1 to transmit it to the infrared sensor 31, thereby avoiding the problem of temperature measurement data attenuation caused by the window angle of the infrared sensor 31 being blocked, thereby improving the temperature measurement accuracy of the pot body 1 by the infrared sensor 31.
[0040] Moreover, the infrared sensor 31 is arranged on the side of the heating device 2 away from the pot body 1, so that the infrared sensor 31 can measure the temperature of the pot body 1 outside the electromagnetic field area of the heating device 2, and the infrared sensor 31 can be protected from electromagnetic interference, thereby further improving the accuracy of the infrared sensor 31 in measuring the temperature of the pot body 1.
[0041] There are various possible implementations for arranging the infrared sensor 31 on the side of the heating device 2 away from the pot body 1. For example, the infrared sensor 31 can be arranged on the heating device 2; or the cooking device can further include a housing, with the pot body 1, heating device 2, and temperature measuring component 3 all arranged inside the housing, and a mounting bracket can further be provided within the housing, with the infrared sensor 31 arranged on the mounting bracket.
[0042] In some embodiments, see Figure 1 and Figure 2 The heating device 2 may be provided with a through hole 21 facing the pot body 1 ; the detection end of the infrared sensor 31 is connected to the through hole through the guide portion 32 .
[0043] By opening a through hole 21 on the heating device 2, and the through hole 21 is set toward the pot body 1, the infrared waves radiated by the pot body 1 can directly enter the guide part 32 through the through hole 21, and finally be transmitted to the infrared sensor 31 through the guide part 32. This can make it easier for the guide part 32 to transmit the infrared waves to the infrared sensor 31, thereby better avoiding the attenuation of the temperature measurement data, better measuring the surface temperature of the pot body 1 at a distance, and further improving the temperature measurement accuracy of the pot body 1 by the infrared sensor 31.
[0044] In the above embodiment, the heating device 2 may include a bracket and a coil wound on the bracket, the through hole 21 may be opened on the bracket, and the through hole 21 corresponds to the position to be temperature measured on the pot body 1.
[0045] In some embodiments, see Figure 2 、 Figure 3 or Figure 5 The guide portion 32 may include a guide channel 321 , an input end of the guide channel 321 is communicated with the through hole 21 , and an output end of the guide channel 321 is connected to the infrared sensor 31 .
[0046] The infrared waves radiated by the pot body 1 can enter the guide channel 321 through the through hole 21 and reach the infrared sensor 31 under the transmission of the guide channel 321, thereby conveniently realizing the transmission of the infrared waves radiated by the pot body 1 by the guide part 32, with a simple structure and reliable use.
[0047] The guide channel 321 may extend in a straight line, and the inner wall surface of the guide channel 321 may be a smooth surface, so that the infrared wave can be conveniently and quickly transmitted to the infrared sensor 31 along a straight line.
[0048] In some embodiments, see Figure 3 and Figure 4 The guide portion 32 may include a cylinder 322 with openings at both ends, one end of the cylinder 322 is connected to the through hole 21, and the other end of the cylinder 322 is connected to the detection end of the infrared sensor 31; the interior of the cylinder 322 defines a guide channel 321.
[0049] Infrared waves radiated from the pot body 1 can enter the cylinder 322 through the through hole 21 and reach the infrared sensor 31 under the transmission of the cylinder 322. The cylinder, heating device, and infrared sensor can all be detachably connected to facilitate replacement and maintenance of the temperature measurement components. Specifically, one end of the cylinder 322 can be connected to the heating device 2 via a fastener such as a screw, so that one end of the cylinder 322 is connected to the through hole 21. The other end of the cylinder 322 can also be connected to the infrared sensor 31 via a fastener such as a screw.
[0050] Furthermore, to facilitate the connection between the guide portion 32 and the heating device 2, a guide member can be provided on the outer wall of the cylinder 322, and a guide fitting can be provided on the heating device 2. The guide member and the guide fitting are slidably connected to each other, so that the cylinder 322 can be easily installed in place. At this time, the cylinder 322 and the heating device 2 are connected with fasteners to ensure that the cylinder 322 is connected to the through hole 21, making operation more convenient. Specifically, the guide member can be a guide rail extending along the length of the cylinder 322, and the guide fitting can be a slide groove.
[0051] In some embodiments, see Figure 2 、 Figure 3 and Figure 4 The guide portion 32 may further include a blocking member 323 , which is disposed in the guide channel 321 to block the guide channel 321 ; the blocking member 323 may be a light-transmitting member.
[0052] Because the blocking member 323 can block the guide channel 321, it can prevent foreign matter such as oil smoke and dust from entering the guide channel 321, thereby preventing foreign matter from affecting the temperature measurement of the infrared sensor 31 and further ensuring the temperature measurement accuracy of the infrared sensor 31. At the same time, because the blocking member 323 is a light-transmitting member, the infrared waves radiated by the pot body 1 can pass through the blocking member 323 and enter the guide channel 321, thereby ensuring the normal transmission function of the guide channel 321 for the infrared waves.
[0053] The infrared waves radiated by the pot body 1 are typically of wavelengths between 0.5 and 2.5 microns. The blocking member 323 can be any component that is transparent to infrared waves of wavelengths between 0.5 and 2.5 microns and capable of blocking foreign matter. Specifically, the blocking member 323 can be a glass sheet, such as quartz glass, borosilicate glass, or glass-ceramics.
[0054] In some embodiments, see Figure 3 The blocking member 323 can be positioned at the input end of the guide channel 321; its outer surface can protrude from the end face of the guide channel 321; or its outer surface can be flush with the end face of the guide channel 321. Compared to a configuration where the blocking member 323 is recessed from the input end of the guide channel 321, this configuration prevents foreign matter from accumulating on the blocking member 323 and facilitates timely cleaning of the blocking member 323, thereby ensuring reliable light transmission.
[0055] In some embodiments, the guide portion 32 may further include a first anti-reflection layer. The first anti-reflection layer is provided on at least the outer surface of the inner and outer surfaces of the blocking member 323. This increases the transmittance of infrared waves with a wavelength of 0.5-2.5 microns through the blocking member 323, thereby improving the transmission efficiency of the infrared waves radiated from the pot body 1 by the guide portion 32.
[0056] Alternatively, a first anti-reflection layer may be provided on both the outer and inner surfaces of the blocking member 323 to better improve the transmittance of infrared waves in the blocking member 323. The method may be selected according to actual needs. Specifically, the first anti-reflection layer may be an anti-reflection film.
[0057] The structure of the guide portion 32 is not limited to the above structure. In other embodiments, see Figure 3 and Figure 4 In addition to the cylindrical body 322 and the blocking member 323, the guide portion 32 may also include a lens 324. The lens 324 is disposed in the guide channel 321 and is located between the blocking member 323 and the detection end of the infrared sensor 31. The lens 324 is used to focus the infrared waves transmitted into the guide channel 321 onto the infrared sensor 31.
[0058] In the above embodiment, by arranging a lens in the guide channel 321, the lens can focus the infrared waves transmitted to the guide channel 321 on the infrared sensor 31, so that the infrared sensor can measure infrared waves with a greater distance and a smaller window from it, thereby better avoiding the attenuation of the temperature measurement data obtained by the infrared sensor, and further improving the temperature measurement accuracy of the pot body 1 by the infrared sensor 31.
[0059] The lens 324 can have various structural forms. For example, the lens 324 can be a glass convex lens, a Fresnel lens, etc., and its material can transmit infrared waves with a wavelength of 0.5-2.5 microns.
[0060] In order to facilitate the installation of the blocking member 323 and the lens 324, in some embodiments, see Figure 3 and Figure 4 The guide channel 321 may include a first channel 3211 and a second channel 3212 that are connected to each other. The free end of the first channel 3211 is the input end of the guide channel 321, and the free end of the second channel 3212 is the output end of the guide channel 321; the cylinder 322 may include a first cylinder 3221 and a second cylinder 3222, both of which are open at both ends. The interior of the first cylinder 3221 defines the first channel 3211, and the interior of the second cylinder 3222 defines the second channel 3212. The first cylinder 3221 and the second cylinder 3222 are detachably connected; the second cylinder 3222 is connected to the detection end of the infrared sensor 31; the blocking member 323 is arranged in the first channel 3211; and the lens 324 is arranged in the second channel 3212.
[0061] The blocking member 323 can be disposed at the free end of the first channel 3211 to seal the entire guide channel 321 formed by the first channel 3211 and the second channel 3212 to prevent foreign matter from entering. A lens 324 can be disposed on the end of the second channel 3212 opposite to the free end thereof to focus infrared waves on the infrared sensor 31.
[0062] When assembling the temperature measuring assembly 3, first install the blocking member 323 on the first barrel 3221 and the lens 324 on the second barrel 3222. Then, connect the second barrel 3222 to the infrared sensor 31. Finally, connect the second barrel 3222 to the first barrel 3221. This completes the assembly of the temperature measuring assembly 3. To disassemble the temperature measuring assembly 3, follow the reverse steps of the assembly process. The temperature measuring assembly 3 is easy to assemble and disassemble, making it convenient for maintenance and replacement.
[0063] Specifically, there may be various ways of detachably connecting the first cylinder 3221 and the second cylinder 3222 , such as bolt connection, snap connection, etc.
[0064] The guide channel 321 is not limited to the above-mentioned structure defined by the inner portion of the cylindrical structure. In other embodiments, see Figure 5 , the guide channel 321 can be an optical fiber.
[0065] In the above embodiment, optical fiber is used to transmit the infrared waves radiated by the pot body 1. After the infrared waves enter the optical fiber from the input end of the optical fiber, they are transmitted inside the optical fiber and finally output from the output end of the optical fiber, thereby transmitting the infrared waves to the infrared sensor 31.
[0066] Moreover, since optical fiber is a bendable material, light is used as the guide channel 321, so that the guide channel 321 can be bent, thereby making the position of the infrared sensor 31 adjustable, thereby effectively saving the space occupied by the temperature measuring component 3, and also enabling the temperature measuring component 3 to adapt to temperature detection in complex environments.
[0067] In order to improve the transmittance of the optical fiber to infrared waves with a wavelength of 0.5-2.5 microns, in some embodiments, the end face of the input end of the optical fiber can be provided with a second anti-reflection layer. Specifically, the second anti-reflection layer can be an anti-reflection film.
[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
