The probe assembly 62 includes a probe 621, a circuit board 622 electrically connected to the probe 621, and a wire 623 electrically connected to the circuit board 622. The wire 623 is wound by the winding structure 63 and extends out of the shell 61 and is electrically connected to the control module of the range hood. By arranging a winding structure 63 in the accommodating cavity of the shell 611, the wire 623 can be organized and protected, and when the shell cover 612 is assembled to the shell 611, the wire 623 wound on the winding structure 63 will not become loose. On the one hand, it is convenient for the assembly of the shell cover 612 and the shell 611, and on the other hand, the shell cover 612 can also fix the wire 623 wound on the winding structure 63.

[0041] The wire 623 includes an internal wire and an external wire, one end of the internal wire is electrically connected to the circuit board 622, the internal wire is wound around the winding structure 63, the other end of the internal wire is electrically connected to one end of the external wire through a connector, the connector is located in the accommodating cavity, and the other end of the external wire passes through the housing 61. By placing the connector in the accommodating cavity, the connector can be prevented from being contaminated by oil smoke.

[0042] The temperature sensing detection device 60 also includes a partition plate 64, which is arranged in the accommodating cavity of the shell 611.

When installing the temperature sensing detection device 60, first insert the housing 61 of the temperature sensing detection device 60 from the outer side of the lining plate 51 into the mounting hole 511 and detachably connect to the lining plate 51, and make the first light-transmitting hole of the temperature sensing detection device 60 face the outer side of the lining plate 51; then connect the lower panel 52 to the outer side of the lining plate 51, and ensure that the second light-transmitting hole 521 is directly opposite to the first light-transmitting hole. On the one hand, the shell 61 of the temperature sensing detection device 60 blocks the mounting hole 511, thereby preventing oil smoke, water mist or impurities from entering the interior of the range hood through the mounting hole 511; on the other hand, the temperature sensing detection device 60 and the lining plate 51 are detachably connected, so when the temperature sensing detection device 60 needs to be maintained / replaced, the temperature sensing detection device 60 can be conveniently disassembled from the outside of the range hood without disassembling the range hood, which greatly improves the convenience of maintenance / replacement of the temperature sensing detection device 60.

[0046] The housing 61 also includes an end plate portion 6112, which abuts against the outer side of the lining plate 51. The abutment between the end plate portion 6112 and the lining plate 51 can not only play a limiting role when the temperature sensing detection device 60 is inserted into the installation hole 511, preventing the user from using excessive force when installing the temperature sensing detection device 60 and completely pushing the temperature sensing detection device 60 into the range hood, but also ensure the accuracy of the installation position of the temperature sensing detection device 60. In addition, the abutment between the end plate portion 6112 and the lining plate 51 can also play a sealing role at the installation hole 511, further improving the effect of blocking external oil smoke, impurities, etc. from entering the interior of the range hood. In this embodiment, the end plate portion 6112 is arranged around the end of the housing 611 away from the opening. In this embodiment, a receiving groove is provided on the outer side of the lining plate 51, and the end plate portion 6112 is arranged in the receiving groove and abuts against the bottom of the receiving groove. By providing the receiving groove, the end surface of the end plate portion 6112 does not protrude from the outer side surface of the lining plate 51, so as to facilitate the fitting installation of the lower panel 52 and the lining plate 51.

[0047] An anti-foolproof structure is provided between the lining plate 51 and the housing 61 of the temperature sensing detection device 60 to improve the convenience and accuracy of the temperature sensing detection device 60 when it is installed on the lining plate 51. Specifically, the anti-foolproof structure includes an anti-foolproof protrusion 66 and an anti-foolproof notch 5111. The anti-foolproof protrusion 66 is provided on one of the outer wall of the housing 61 and the inner wall of the mounting hole 511, and the anti-foolproof notch 5111 is provided on the other, and the anti-foolproof protrusion 66 is located in the anti-foolproof notch 5111. When the housing 61 is inserted into the mounting hole 511, the anti-foolproof protrusion 66 must be aligned with the anti-foolproof notch 5111 to correctly complete the assembly of the housing 61 and the lining plate 51, thereby making the installation more convenient and accurate. This embodiment shows a situation where the anti-foolproof protrusion 66 is arranged on the outer wall of the shell 61, and the anti-foolproof notch 5111 is arranged on the inner wall of the mounting hole 511. It can also be that the anti-foolproof protrusion 66 is arranged on the inner wall of the mounting hole 511, and the anti-foolproof notch 5111 is arranged on the outer wall of the shell 61. The specific arrangement can be made according to needs.
