Note that the temperature at the burner 700 may include the temperature of the area covered by the burner 700; optionally, the temperature at the burner 700 may include a temperature within a predetermined distance (e.g., 10 centimeters) around the burner 700 in addition to the temperature of the area covered by the burner 700. One skilled in the art can select the temperature acquisition range of the pyroelectric module 300. Regardless, the temperature acquisition range of the heat releasing module 300 is generally preset at the time of manufacturing or installing the range hood 100, and is known to the heat releasing module 300. It will be appreciated that in the case of a pan above the burner 700, the temperature of the burner 700 is the temperature within the cooktop above it.

While the user is cooking, the heat release module 300 may detect temperature data at the burner 700 and transmit the temperature data to other mechanisms. For example, the temperature data may be communicated to a control device of the range hood 100, which may control the drive mechanism to turn on or off the air deflectors of the range hood 100 based on the temperature data. In addition, the control device can also transmit the temperature data to the communication module for transmission to other devices. For example, the temperature data is sent to the kitchen range, and the kitchen range can control the firepower of the kitchen range according to the temperature data; and also for example to a server for monitoring and storing temperature data, etc.

The pyroelectric mechanism 200 further includes a protective sheet 500 mounted on the fixing member 400 and covering at least the probing tip 310 from the outside.

With the cover 600 in the illustrated position, the probe head 310 is fully illustrated with respect to the exterior of the pyroelectric mechanism 200. At this time, the probe 310 may detect temperature data at the burner 700. When the cover 600 is in the covering position, the probing tip 310 is completely covered with respect to the exterior of the pyroelectric mechanism 200. At this time, the probing tip 310 is completely covered by the cover 600. Illustratively, the cover 600 may be switched between the illustrated position and the covering position by a sliding structure, a flip structure, or other structures. The switching of the cover 600 between the illustrated position and the covering position may be in a manual or automatic fashion.

Through this kind of setting, when the user when the culinary art, can make lid 600 be in and show the position, the temperature data that furnace end 700 was located can be surveyed to detecting head 310, after the culinary art was finished, can make lid 600 be in and hide the position, prevent that there is oil smoke, dust or other foreign matters from getting into to release the inside protection piece 500 that causes of mechanism 200 and polluting or destroying, played the effect of protection piece 500.

Illustratively, as shown in fig. 2 to 5, the cover 600 covers the probing tip 310 from the front end of the fixing assembly 400, and the side surface 470 of the fixing assembly 400 is provided with a first sliding groove 471 and a second sliding groove 472, and the first sliding groove 471 and the second sliding groove 472 extend along the front end surface 320 (shown in fig. 5) of the probing tip 310. That is, the first sliding groove 471 and the second sliding groove 472 are both parallel to the front end surface 320. In a plane parallel to the front end surface 320, the first sliding groove 471 and the second sliding groove 472 are communicated through the inclined groove 473 at the end portions close to each other, an included angle between the first sliding groove 471 and the inclined groove 473 and the second sliding groove 472 is an obtuse angle, and the first sliding groove 471 is closer to the detecting head 310 relative to the second sliding groove 472. The first sliding groove 471 is spaced farther from the front end of the fixing member 400 than the second sliding groove 472 is spaced from the front end of the fixing member 400 in a direction perpendicular to the front end surface 320 of the probing tip 310. Through the arrangement of the sliding groove structure, the functions of protecting the protection sheet 500 and reducing the sliding resistance can be realized by matching with the cover body 600.

Illustratively, as shown in fig. 6, the cover body 600 is provided with a slider 610, and the slider 610 slides within the first sliding groove 471, the second sliding groove 472, and the inclined groove 473 described above to slide reciprocally between the illustrated position and the covering position. Since the first sliding groove 471 is closer to the probe head 310 than the second sliding groove 472 in a plane parallel to the front end surface 320, the slider 610 is located in the first sliding groove 471 when the cover body 600 is in the covering position, and the slider 610 is located in the second sliding groove 472 when the cover body 600 is in the illustrated position. In addition, since the distance from the first chute 471 to the detecting head 310 is greater than the distance from the second chute 472 to the detecting head 310 in the direction perpendicular to the front end face 320, when the cover body 600 is at the covering position, the cover body is relatively close to the front end face 320 of the detecting head 310 in the direction perpendicular to the front end face 320, a gap between the cover body 600 and the fixing assembly 400 is small, oil smoke, dust or other foreign objects are difficult to enter the heat releasing mechanism 200 to cause pollution or damage to the protection sheet 500, and the protection sheet 500 is protected. When the cover 600 is in the illustrated position, it is relatively far from the probe head 310 in a direction perpendicular to the front face 320, and the gap between the cover 600 and the stationary assembly 400 is large. Thus, friction between the cover 600 and the fixing member 400 is prevented during sliding, which increases sliding resistance and thus damages the cover 600 and the fixing member 400. Therefore, the structure is reasonable in design and convenient to use.

Illustratively, as shown in fig. 2 and 6, the cover body 600 includes a front cover 620 and side walls 630, the front cover 620 is located in front of the fixing assembly 400 and is parallel to the front end surface 320, the side walls 630 extend from both sides of the front cover 620 toward the probing tips 310, and the slider 610 is disposed on the side walls 630. Thus, the cover 600 has a U-shape. The U-shaped cover 600 covers the probing tip 310 from the front of the fixing assembly 400. The slider 610 may be disposed inside the sidewall 630 as shown. The slider 610 may have a cylindrical shape. The cover 600 may be an integral structure, or may be formed by screwing, adhering, or otherwise combining after being formed separately. With this arrangement, when the cover body 600 is in the covering position, the front cover 620 and the side wall 630 can better protect the inside of the heat releasing mechanism 200. Moreover, the cover body 600 also has the advantages of simple structure, convenient processing and the like.

Illustratively, the guard plate 500 comprises a silicon wafer. Silicon is inactive at normal temperature, has no obvious effect on air, water, acid and the like, and has high mechanical strength. Silicon is one of the most abundant elements in the earth crust, and the price is relatively low. Silicon has a high transmittance for infrared rays. Therefore, the silicon chip is selected to meet the working requirements of the probe 310, and also has a good protection effect on the probe 310, and meanwhile, the silicon chip is low in price and low in cost.
