Description

Technical Field

[0001] This invention relates to the field of electrical technology, and more particularly to a kitchen appliance. Background Technology

[0002] A range hood, also known as a kitchen exhaust hood, is a kitchen appliance used to purify the kitchen environment. Installed above the gas stove, it can quickly remove the waste from the burner and the harmful fumes produced during cooking, expelling them outdoors, reducing pollution, and purifying the air.

[0003] With the improvement of automation, existing range hoods are beginning to incorporate temperature sensing modules to monitor the concentration of cooking fumes so that the range hood can make timely adjustments. Temperature sensing modules typically operate in environments with cooking fumes, oil droplets, water mist, and water droplets. Since temperature sensing modules include electrical components such as detection probes and circuit boards, cooking fumes, oil droplets, water mist, and water droplets can cover the outside of the temperature sensing module or enter its interior, affecting the detection accuracy of the temperature sensing module. In severe cases, it can even affect the normal operation of the temperature sensing module and reduce its service life.

[0004] Therefore, there is an urgent need for a kitchen appliance to solve the above-mentioned technical problems. Summary of the Invention

[0087] Example 1

[0088] This embodiment provides a kitchen appliance, which includes a temperature sensing module 2. The kitchen appliance can adjust its working mode according to the temperature detected at a target location by the temperature sensing module 2. Specifically, the kitchen appliance can be, but is not limited to, a range hood, an integrated stove, etc. In this embodiment, a range hood is used as an example, and the temperature sensing module 2 can detect the temperature of the stove or countertop below the range hood for detailed description.

[0089] like Figure 1 As shown, the range hood includes a frame 1, a fan, an air inlet duct, and an exhaust duct, with the fan supported on the frame 1. Both the air inlet and exhaust ducts are formed on the frame 1. When the fan is operating, cooking fumes enter through the air inlet duct, pass through the fan, and are exhausted outdoors through the exhaust duct. Figure 1As shown, in this embodiment, the range hood includes a panel 11, which is the outermost plate of the range hood. Optionally, the panel 11 can be a glass plate, which is aesthetically pleasing and easy to clean. In other embodiments, the panel 11 can also be sheet metal. It should be noted that in this embodiment, the descriptions of front, back, left, right, up, and down are all based on the position of the range hood relative to the user.

[0090] like Figure 1 and Figure 2 As shown, the panel 11 has an opening (not shown). The range hood also includes a control module and a temperature sensing module 2. The light emitted or received by the temperature sensing module 2 passes through the opening, thereby detecting the temperature of the cooktop or countertop below the range hood. Specifically, as... Figure 3 As shown, the temperature sensing module 2 includes a body 21, which includes a housing, a detection probe 213, and a circuit board 214. The housing has a receiving cavity, within which the detection probe 213 and the circuit board 214 are both disposed. The detection probe 213 is electrically connected to the circuit board 214. One end of the first wire assembly 23 is electrically connected to the circuit board 214, and the other end extends out of the housing and connects to the control module of the range hood. The temperature sensing module 2 forms an integral structure, facilitating independent maintenance and replacement. The housing protects the detection probe 213 and the circuit board 214, thereby extending the service life of the temperature sensing module 2. Figure 3 As shown, a light-transmitting opening 215 is provided on the housing. The light emitted or received by the detection probe 213 passes through the light-transmitting opening 215, thereby realizing the temperature detection of the outside of the housing. The detection probe 213 detects the temperature data and sends it to the circuit board 214. The circuit board 214 sends the corresponding control command to the control module according to the received temperature data. After receiving the control command from the detection probe 213, the control module of the range hood adjusts the working mode of the fan accordingly, thus realizing the automatic adjustment of the range hood's smoke extraction mode and improving the user experience.

[0091] Since both the detection probe 213 and the circuit board 214 are housed within the casing, the communication distance between them is short, allowing the circuit board 214 to quickly receive the temperature data detected by the probe 213. Furthermore, due to the short communication path, the temperature data is not distorted. Because the control commands issued by the circuit board 214 to the range hood's control module are in simple binary form, the control commands are less affected by longer communication paths, thus not affecting the precise control of the range hood. It should be noted that the detection probe 213 and the circuit board 214 are electrically connected via a second wiring assembly. Both the first wiring assembly 23 and the second wiring assembly include a power line, a ground line, and a communication line for signal transmission. This embodiment does not limit the type of detection probe 213; for example, it can be configured as an active infrared temperature sensor or a passive infrared temperature sensor. Active infrared temperature sensors emit infrared rays. These rays are reflected upon contact with the object being measured and then re-received by the active infrared temperature sensor, thus measuring the object's temperature. Passive infrared temperature sensors work by radiating infrared radiation when the object's temperature is above thermodynamic zero. The passive infrared temperature sensor detects this radiation energy to measure the object's temperature. Any infrared temperature sensor capable of non-contact temperature measurement of an object, other than the two types mentioned above, falls within the scope of this invention. When the detection probe 213 is an active infrared temperature sensor, the infrared rays emitted by the probe 213 pass through the light-transmitting port 215 and then through an opening to the outside of the range hood. The reflected light from the object passes through an opening on the panel 11 and then through the light-transmitting port 215 to be received by the detection probe 213. For the detection probe 213, which is an active infrared temperature sensor, the infrared rays radiated by the external stove or countertop are received by the detection probe 213 after passing through the opening on the panel 11 and the light-transmitting port 215, thereby enabling the detection probe 213 to detect the temperature.

[0092] like Figure 3 As shown, the main body 21 also includes a filter assembly, which is installed at the light-transmitting port 215. Specifically, the filter assembly includes a filter 217, which can be a silicon wafer. The silicon wafer can filter out stray light other than infrared light, ensuring that the radiation energy entering the detection probe 213 is only infrared radiation energy, thereby improving the measurement accuracy of the infrared temperature detection mechanism.

[0093] like Figure 3 and Figure 16As shown, the housing includes an outer shell 211 and a cover 212. The outer shell 211 includes a receiving cavity with a second opening 2119. The cover 212 covers the second opening 2119 to form the receiving cavity. The detection probe 213 and the circuit board 214 can be installed into the receiving cavity from the second opening. In this embodiment, the light-transmitting opening 215 is formed on the outer shell 211. The main body 21 also includes an inner support member 216, which is located within the receiving cavity. The detection probe 213 and the circuit board 214 are both mounted on the inner support member 216. Therefore, when installing the temperature sensing module 2, the detection probe 213 and the circuit board 214 can be first installed on the inner support member 216 outside the receiving cavity, and then the whole assembly can be installed into the receiving cavity, which improves the convenience of assembly. In addition, by positioning the detection probe 213 through the inner support member 216, it can be ensured that the receiving end or transmitting end of the detection probe 213 is aligned with the light-transmitting opening 215, thereby ensuring accurate reception / emission of light paths.

[0094] like Figure 3 As shown, the temperature sensing module 2 includes at least two detection probes 213. The center lines of the light paths emitted or received by the at least two detection probes 213 are arranged at an angle, thereby enabling the detection of temperature conditions in different areas. Since the light paths emitted or received by the at least two detection probes 213 pass through the same filter assembly, the number of filter assemblies can be reduced, simplifying the structure of the temperature sensing module. In this embodiment, the temperature sensing module includes two detection probes 213. The intersection of the center lines of the light paths emitted or received by the two detection probes 213 is located on the side of the detection probe 213 near the light-transmitting opening 215. Therefore, the size of the light-transmitting opening 215 and the filter assembly can be reduced, making the overall structure of the temperature sensing module 2 more compact. Furthermore, the size of the openings on the panel 11 is reduced, thereby improving the aesthetics of the range hood. In this embodiment, both detection probes 213 are mounted on the inner support member 216, meaning the two detection probes 213 share the same limiting reference. This facilitates ensuring the relative positional accuracy between the two detection probes 213, thereby ensuring the detection accuracy of the entire temperature sensing module 2.

[0095] To enable the temperature sensing module 2 to be installed on the panel 11, such as Figure 2 As shown, the range hood includes a mounting bracket 5, which is connected to the inner side of the frame. Specifically, the mounting bracket 5 is installed on the inner side of the panel 11, and the temperature sensing module 2 is connected to the mounting bracket 5, thereby achieving connection with the panel 11. In this embodiment, as... Figure 2 As shown, the mounting bracket 5 is a sheet metal bending structure, which has high structural strength and light weight. Specifically, as... Figure 2 and Figure 4As shown, the mounting bracket 5 includes a connecting portion 51, a supporting portion 52, and two reinforcing portions 53. The connecting portion 51 is parallel to the panel 11 and is used for connection to the panel 11. The supporting portion 52 is connected to the connecting portion 51 and is perpendicular to the panel 11. In this embodiment, the reinforcing portions 53 are plate-shaped, and two reinforcing portions 53 are connected to the left and right ends of the connecting portion 51 and are perpendicular to the connecting portion 51. The reinforcing portions 53 are supported below the supporting portion 52. The connecting portion 51, the supporting portion 52, and the reinforcing portions 53 support each other, improving the structural strength of the mounting bracket 5 and thus ensuring the firmness of the connection of the temperature sensing module 2. In other embodiments, the mounting bracket 5 may also be provided with one or more reinforcing portions 53, and the shape of the reinforcing portions 53 is not limited to a plate shape; the reinforcing portions 53 may also be rib structures supporting the supporting portion 52 and the connecting portion 51.

[0096] In some cases, the panel 11 is supported by an aesthetically pleasing glass material, making it unsuitable for machining. In this embodiment, the mounting bracket 5 is connected to the panel 11 via adhesive bonding, thereby improving the ease of connection between the mounting bracket 5 and the panel 11 and ensuring a smooth and aesthetically pleasing outer surface of the panel 11. Figure 4 and Figure 5 As shown, the connecting part 51 has at least two protrusions 54 on the side facing the panel 11, and the at least two protrusions 54 are of equal height. The protrusions 54 abut against the panel 11 to form a gap 6 between the connecting part 51 and the panel 11. An adhesive layer is poured into the gap 6 to achieve the connection between the mounting bracket 5 and the panel 11. By providing multiple protrusions 54, the connecting part 51 and the panel 11 are kept parallel, ensuring the accuracy of the installation posture of the entire mounting bracket 5. The at least two protrusions 54 of equal height ensure that the thickness of the gap 6 formed between the connecting part 51 and the panel 11 is consistent, which not only ensures the accuracy of the installation position of the connecting part 51, but also ensures that the thickness of the adhesive poured into the gap 6 is uniform at all positions of the connecting part 51, making the connection of the mounting bracket 5 stable and reliable.

[0097] like Figure 4 As shown, the connecting part 51 is provided with an injection hole 511, which allows glue to be injected into the gap 6 between the connecting part 51 and the panel 11, improving the convenience of glue injection. Figure 4 As shown, the connecting part 51 is provided with a plurality of glue injection holes 511. The plurality of glue injection holes 511 are evenly distributed on the connecting part 51, so glue can be injected into the gap 6 from the plurality of glue injection holes 511 respectively, thereby improving the uniformity of the glue layer distribution in the gap 6.

[0098] Optionally, the temperature sensing module 2 is provided with a through hole 221, and the mounting bracket 5 is provided with a mounting hole 521. The range hood also includes a fixing member, which passes through the through hole 221 and the mounting hole 521 in sequence, thereby mounting the temperature sensing module 2 on the mounting bracket 5. Specifically, in this embodiment, the fixing member is a bolt, and the mounting hole 521 is a threaded hole. The fixing member passes through the through hole 221 and is threadedly connected to the threaded hole. In other embodiments, the mounting hole 521 can also be a smooth hole, and the fixing member includes a bolt and a nut. The bolt passes through the through hole 221 and the mounting hole 521 in sequence and is then connected to the nut. The axis of the through hole 221 is inclined relative to the axis of the mounting hole 521 so that the temperature sensing module 2 abuts against the inner side of the frame 1.

[0099] Specifically, the axis of the through hole 221 is inclined away from the panel 11 in a top-to-bottom direction. When the fastener is installed from top to bottom, a force is applied to the mounting plate 22, causing it to press against the panel 11, thus pressing the entire temperature sensing module 2 firmly onto the panel 11. Therefore, the gap between the temperature sensing module 2 and the panel 11 can be minimized. Even if some oil droplets enter the protective component 3, the oil droplets will not enter the space between the temperature sensing module 2 and the panel 11, preventing oil droplets from soaking into the silicon wafer and affecting the detection accuracy of the detection probe. In this embodiment, the temperature sensing module 2 also includes two mounting plates 22, which are disposed on the left and right sides of the body 21, with the through hole 221 disposed on the mounting plate 22. The range hood includes two mounting brackets 5, which are respectively disposed on the left and right sides of the body 21. The two mounting plates 22 of the temperature sensing module 2 are respectively attached to the support portion 52 on the mounting bracket 5, with the mounting hole 521 disposed on the support portion 52.

[0100] During the operation of the range hood, on the one hand, oil or water droplets will accumulate in the internal structure, such as the air intake duct, and these droplets may fall onto the temperature sensing module 2. On the other hand, oil fumes or water mist in the air intake duct may move to the temperature sensing module 2, causing excessive oil fumes to accumulate on the windward side of the temperature sensing module 2 (i.e., the side of the temperature sensing module 2 closest to the air intake duct). With prolonged use, the dripping oil droplets or accumulated oil fumes may enter the housing, thereby affecting the detection accuracy and lifespan of the temperature sensing module 2.

[0101] To address this, the range hood in this embodiment also includes a protective component 3. The protective component 3 is located inside the frame 1 and on the windward side of the temperature sensing module 2. The protective component and the frame 1 form a receiving space, within which at least a portion of the temperature sensing module 2 is located. This prevents oil fumes, oil droplets, water mist, and water droplets from covering the outside of the temperature sensing module or entering its interior, ensuring that even under prolonged use, the detection probe maintains good detection accuracy, and the electrical components function normally, thereby improving the detection accuracy and lifespan of the temperature sensing module.

[0102] In this embodiment, as Figure 1 As shown, the air inlet is located above panel 11, which is also above the temperature sensing module 2. Since the upper part is the windward side of the temperature sensing module 2, oil droplets will move downwards towards it. To address this, a protective element 3 covers the upper and side of the temperature sensing module 2. Optionally, the side may only include the rear side of the temperature sensing module 2. Alternatively, the side may include at least one of the left and right sides of the temperature sensing module 2, as well as the rear side. By configuring the protective element 3 in this way, not only can oil droplets from the structure above the temperature sensing module 2 within the frame 1 be prevented from falling onto the temperature sensing module 2, but it can also block oil fumes from the air inlet, preventing oil fumes from accumulating on the temperature sensing module 2. In this embodiment, the protective element 3 simultaneously covers the upper, left, right, and rear sides of the temperature sensing module 2.

[0103] In other embodiments (not shown), the air inlet is located below the panel 11, that is, below the temperature sensing module 2. In this case, the area below is the windward side of the temperature sensing module 2, so the fumes from the air inlet will move upwards towards the temperature sensing module 2. In this embodiment, the protective component 3 covers the lower and side surfaces of the temperature sensing module 2. Optionally, the side surface may include one or more of the rear, left, and right sides of the temperature sensing module 2. Therefore, it can effectively block fumes from the air inlet, preventing fumes from accumulating on the temperature sensing module 2.

[0104] like Figure 2 , Figure 6 and Figure 7 As shown, the protective component 3 includes a cover portion 31, which includes a receiving cavity with a first opening. The cover portion 31 is fastened to the inner side of the frame 1. Specifically, the cover portion 31 is fastened to the inner side of the panel 11. In this embodiment, the cover portion 31 is provided with an opening 311, and the opening 311 is located on the leeward side of the temperature sensing module 2. The first wire assembly 23 extends from the opening 311 of the cover portion 31 to the outside of the protective component 3. By providing the opening 311, it is convenient for the first wire assembly 23 to be electrically connected to the control module of the range hood. Moreover, by placing the opening 311 on the leeward side of the temperature sensing module 2, the deposition of oil fumes or water mist in the air intake channel on the temperature sensing module 2 can be minimized. In addition, in this embodiment, the leeward side is below the temperature sensing module 2, so the cover portion 31 can block the top and sides of the temperature sensing module 2, thus also preventing oil droplets or water droplets from falling onto the temperature sensing module 2.

[0105] In this embodiment, the cover portion 31 has an upper wall 313 located above the temperature sensing module, a rear side wall 312 located behind the temperature sensing module, a left side wall 315 located to the left of the temperature sensing module, and a right side wall 316 located to the right of the temperature sensing module. The upper wall 313 is approximately perpendicular to the panel 11, the rear side wall 312 is opposite to and approximately parallel to the panel 11, and the left side wall 315 and right side wall 316 are respectively located on the left and right sides of the temperature sensing module 2. That is, after the cover portion 31 is installed on the panel 11, it forms a receiving space with an opening 311 at its lower end, and the body portion 21 of the temperature sensing module 2 is disposed within this receiving space. In this embodiment, the temperature sensing module 2 is located in the middle of the receiving space along the left-right direction. The first wire assembly 23 of the temperature sensing module 2 extends from the opening 311 to the outside of the protective member 3.

[0106] like Figure 6 As shown, the protective component 3 also includes a flanged portion 32, which extends outward from the first opening and abuts against the inner side of the frame 1. In this embodiment, the flanged portion 32 abuts against the inner side of the panel 11. The flanged portion 32 allows the protective component 3 to fit more fully against the inner wall of the panel 11, improving the sealing between the protective component 3 and the panel 11, thereby effectively preventing oil droplets from entering the interior of the protective component 3 from the position where the panel 11 abuts against the protective component 3 and falling onto the temperature sensing module 2. In this embodiment, the flanged portion 32 is located at the edges of the left side wall 315, right side wall 316, and upper wall 313 facing the panel 11.

[0107] like Figure 2 and Figure 6 As shown, the range hood also includes a cover seal 4, which is sandwiched between the protective member 3 and the frame 1. The cover seal 4 further improves the sealing effect between the protective member 3 and the frame 1, thereby further reducing the possibility of oil droplets entering the protective member 3 through the gap between the protective member 3 and the panel 11. Specifically, in this embodiment, the cover seal 4 is sandwiched between the flanged portion 32 of the protective member 3 and the panel 11. The cover seal 4 can be a rubber strip.

[0108] like Figure 6As shown, the upper wall 313 of the protective component 3 includes a first end and a second end. The first end is connected to the rear side wall 312, and the second end is directly opposite the frame 1. The upper wall 313 tends to slope downwards or bend from the first end to the second end. In this embodiment, an arc surface is formed between the upper wall 313 and the flange 32, which can guide oil droplets falling on the flange 32, preventing oil or water droplets from depositing between the flange 32 and the panel 11 and entering the protective component 3, thereby further improving the oil-blocking effect of the protective component 3. An arc surface is also formed between the upper wall 313 and the rear side wall 312, so oil or water droplets can be guided to the rear side wall 312 of the protective component 3 and eventually fall off the protective component 3, preventing excessive oil droplet deposition on the protective component 3. In other embodiments, the upper wall 313 may also be an inclined plane, and the end of the upper wall 313 connected to the flange 32 is higher than the end connected to the rear side wall 312, so as to smoothly guide the oil droplets or water flow that drips onto the flange 32 or the upper wall 313 to the side of the rear side wall 312 and finally fall off the protective member 3, so as to prevent the oil droplets or water droplets from depositing at the position between the flange 32 and the panel 11 and then entering the protective member 3.

[0109] like Figure 2 and Figure 6 As shown, the rear sidewall 312 of the protective member 3 is adjacent to the opening 311, and the rear sidewall 312 is approximately parallel to the panel 11, meaning that the rear sidewall 312 has a certain angle of inclination. Therefore, oil or water droplets falling on the rear sidewall 312, as well as oil or water droplets from the upper wall 313, will flow along the rear sidewall 312 and drip from its lower end. In this embodiment, an oil-blocking structure 34 is provided on the lower edge of the rear sidewall 312. The oil-blocking structure 34 can prevent oil droplets flowing down the back of the protective member 3 from entering the opening 311, thereby preventing oil or water droplets from falling onto the temperature sensing module. Specifically, in this embodiment, the oil-blocking structure 34 is provided on the rear sidewall 312.

[0110] like Figure 2As shown, the oil-blocking structure 34 includes a diverting section 341 and a draining section 342. The diverting section 341 is located on the back of the protective member 3 and above the opening 311. The diverting section 341 is directly opposite the temperature sensing module in the front-to-back direction. Draining sections 342 are connected to the left and right sides of the diverting section 341, and the draining sections 342 extend from the diverting section 341 to the outer side of the protective member 3 in the left and right directions. The extension paths of the diverting section 341 and the draining section 342 cover the lower end of the back of the protective member 3 in the left and right directions, thus effectively preventing oil or water droplets from falling from the back of the protective member 3 into the opening 311. Specifically, in this embodiment, the diversion section 341 is located at the middle position of the rear sidewall 312 in the left-right direction, and extends from the middle to both ends in the top-to-bottom direction, that is, the diversion section 341 is constructed in a "∧" shape. The two drainage sections 342 are respectively connected to the two ends of the lower end of the diversion section 341 and extend to the left and right ends of the rear sidewall 312. The drainage sections 342 can guide the oil droplets on the rear sidewall 312 from the middle position to both ends, thereby preventing the oil droplets from accumulating too much in the middle position of the rear sidewall 312 and dripping from the middle position, thus preventing the oil droplets from dripping onto the temperature sensing module 2. The drainage section 342 can further guide the oil droplets. On the one hand, it makes the oil droplets evenly distributed on the drainage section 342, reducing the possibility of oil droplets dripping over the oil-blocking structure 34. On the other hand, when there are too many oil droplets, the drainage section 342 can also make the oil droplets drip as far away from the middle part (corresponding to the temperature sensing module 2) as possible, that is, drip as far away from the temperature sensing module 2 as possible, further improving the oil-proof effect on the temperature sensing module 2.

[0111] like Figure 7 As shown, the inner wall of the protective component 3 is provided with a raised rib 38, which can press the temperature sensing module against the inner side of the frame 1. This minimizes the gap between the temperature sensing module 2 and the inner surface of the frame 1. Even if some oil droplets enter the interior of the protective component 3, the oil droplets will not enter the space between the temperature sensing module 2 and the inner surface of the frame 1, thus preventing oil droplets from soaking into the filter and affecting the detection accuracy of the detection probe. In this embodiment, the raised rib 38 is located on the side of the rear sidewall 312 facing the temperature sensing module 2. When the protective component 3 is installed on the mounting bracket 5, the raised rib 38 can press the temperature sensing module 2 tightly against the inner side of the panel 11. In addition, the raised rib 38 can also strengthen the structural strength of the protective component 3. In this embodiment, the raised rib 38 is cross-shaped. In other embodiments, the specific shape of the raised rib 38 is not limited, as long as it can press against the temperature sensing module 2.

[0112] like Figure 2 and Figure 7As shown, the protective component 3 also includes two connecting plates 35, which are respectively disposed on the left and right sides of the cover portion 31. The connecting plates 35 cover the mounting plate 22 and are connected to the mounting bracket 5. On the one hand, the connection between the connecting plates 35 and the mounting bracket 5 can fix the protective component 3, and the fixed connection between the protective component 3 and the temperature sensing module 2 shares a common support structure, simplifying the internal structure of the range hood. On the other hand, the connecting plates 35 can also play a role in blocking oil at the connection position between the mounting plate 22 and the mounting bracket 5. Furthermore, since the connecting plates 35 play a role in blocking oil at the mounting plate 22, the cover portion 31 does not need to cover the mounting plate 22 and the mounting bracket 5, which can correspondingly reduce the volume of the cover portion 31, thereby reducing the space occupied by the entire protective component 3 in the frame 1 and improving the structural compactness of the range hood. Specifically, in this embodiment, the connecting plates 35 of the protective component 3 are fixed to the bearing portion 52 of the mounting bracket 5 by fastening components such as screws. In other embodiments, the specific connection method between the connecting plates 35 and the bearing portion 52 is not limited here.

[0113] like Figure 7 As shown, the edge of the connecting plate 35 has an upward-facing retaining edge 36, which, together with the connecting plate 35 and the cover portion 31, forms a groove. On one hand, the retaining edge 36 increases the structural strength of the connecting plate 35; on the other hand, the groove can accommodate oil droplets dripping from the left side wall 315, right side wall 316 of the cover portion 31, and other structures above the protective member 3, preventing oil droplets from entering the interior of the protective member 3 through the gap between the connecting plate 35 and the panel 11. Figure 2 As shown, in this embodiment, the retaining edge 36 and the flange 32 meet and connect. The cover seal 4 extends between the retaining edge 36 and the panel 11.

[0114] Example 2

[0115] like Figures 8-10 As shown, this embodiment provides a kitchen appliance, specifically a range hood. The working principle of the range hood, the connection structure between the mounting bracket 5 and the panel 11, and the connection structure between the temperature sensing module 2 and the mounting bracket 5 are all the same as in Embodiment 1, and the similarities will not be repeated here. The difference between this embodiment and Embodiment 1 is that a novel protective component 3 is proposed. The structure of the protective component 3 itself and the method of fixing the protective component 3 within the frame 1 are different from those in Embodiment 1, as detailed below:

[0116] like Figure 8 and Figure 9As shown, in this embodiment, the protective component 3 includes a cover portion 31, which includes a receiving cavity with a first opening. The cover portion 31 is fastened to the inner side of the frame 1, and the cover portion 31 and the frame 1 completely cover the temperature sensing module 2, thereby better preventing oil droplets, water droplets, oil fumes, and water mist from covering the temperature sensing module 2. In this embodiment, the protective component 3 is fastened to the inner side of the panel 11, and the protective component 3 can achieve all-round coverage of the temperature sensing module 2 and the mounting bracket 5 above, to the sides (including the left, right, and rear sides), and below.

[0117] Specifically, such as Figure 9 As shown, the cover portion 31 includes an upper wall 313, a lower wall 314, a rear side wall 312, a left side wall 315, and a right side wall 316. The upper wall 313, lower wall 314, rear side wall 312, left side wall 315, and right side wall 316 together enclose a rectangular prism-shaped receiving space. The temperature sensing module 2 and the mounting bracket 5 are both disposed within the receiving space. In other embodiments, as long as the protective component 3 can cover the temperature sensing module 2 in all directions, its specific shape is not limited here.

[0118] In this embodiment, as Figure 8 and Figure 9 As shown, the protective component 3 is provided with a wire outlet 37, which is configured to allow the first wire assembly 23 (not shown in the figure) of the temperature sensing module 2 to extend out of the protective component 3. In this embodiment, the wire outlet 37 is located on the lower wall 314 of the protective component 3. This ensures that the first wire assembly 23 can be smoothly led out of the protective component 3, while also reducing the risk of oil droplets, water droplets, fumes, and water mist entering the interior of the protective component 3 through the wire outlet 37. The size of the wire outlet 37 is preferably just large enough to allow the first wire assembly 23 to pass through. In other embodiments, the wire outlet 37 may also be located on the left side wall 315, the right side wall 316, or the rear side wall 312, and no specific limitation is made here.

[0119] In this embodiment, as Figure 10 As shown, the frame 1 also includes a frame body 12, with the panel 11 fitted onto the outer side of the frame body 12. A protective member 3 is fixed to the inner side of the frame body 12. The frame body 12 has a clearance hole 13, allowing the temperature sensing module 2 and mounting bracket 5 located inside the panel 11 to extend into the receiving space formed by the protective member 3 through the clearance hole 13. The panel 11 and the frame body 12 are detachably connected. Therefore, when maintenance of the temperature sensing module 2 is required, the panel 11 can be removed from the outside of the frame 1, directly removing the temperature sensing module 2 without needing to remove the protective member 3 from inside the frame 1, making operation more convenient. Optionally, in this embodiment, the protective member 3 and the frame body 12 can be fixed by welding, fastening components, or other methods, which are not limited here. It should be noted that the specific structure for the detachable connection between the panel 11 and the frame body 12 can be any of the existing technologies, and is not limited here.

[0120] like Figure 9 As shown, a flange 32 is provided around the edge of the cover 31 facing the panel 11. The flange 32 abuts against the frame body 12 (since the frame body 12 and the panel 11 are in a fitted state, it is equivalent to the flange 32 abutting against the panel 11). By providing the flange 32, the protective component 3 fits more fully against the frame body 12, improving the sealing of the connection between the protective component 3 and the frame 1, thereby effectively preventing oil droplets from entering the interior of the protective component 3 from the connection between the protective component 3 and the frame 1.

[0121] Example 3

[0122] This embodiment provides a kitchen appliance, specifically a range hood. The working principle, connection structure between the mounting bracket and the panel, and connection structure between the temperature sensing module and the mounting bracket of this embodiment are the same as in Embodiment 1, and the similarities will not be repeated here. The main difference between this embodiment and Embodiment 1 is that a novel protective component is proposed. The structure of the protective component itself and the fixing method of the protective component differ from those in Embodiment 1, as detailed below:

[0123] In this embodiment, the protective component includes a cover portion, which includes an accommodating cavity with a first opening. The cover portion is fastened to the inner side of the frame, and the cover portion and the frame completely enclose the temperature sensing module, thereby better preventing oil droplets, water droplets, oil fumes, and water mist from covering the temperature sensing module. In this embodiment, the protective component is fastened to the inner side of the panel, and the protective component can achieve all-round coverage of the temperature sensing module and the mounting bracket above, to the sides (including the left, right, and rear sides), and below. Specifically, the protective component includes an upper wall located above the temperature sensing module, a lower wall located below the temperature sensing module, a left side wall located to the left of the temperature sensing module, a right side wall located to the right of the temperature sensing module, and a rear side wall located behind the temperature sensing module.

[0124] In this embodiment, the protective component has a wiring hole, which is configured to allow the first wire assembly (not shown in the figure) of the temperature sensing module to extend out of the protective component. In this embodiment, the wiring hole is located on the lower wall of the protective component, which, while ensuring the smooth extension of the first wire assembly to the protective component, also reduces the risk of water droplets, oil fumes, and water mist entering the interior of the protective component through the wiring hole. The size of the wiring hole is preferably just large enough to allow the first wire assembly to pass through. In other embodiments, the wiring hole may also be located on the left side wall, right side wall, or rear side wall; no specific limitation is made here.

[0125] It should be noted that in this embodiment, the connection method between the protective component and the frame is the same as in Embodiment 2, and will not be repeated here.

[0126] The edge of the cover facing the panel is provided with a flange, which abuts against the frame body (since the frame body and the panel are in a fitted state, it is equivalent to the flange abutting against the panel). By providing the flange, the protective component fits more fully against the frame body, improving the sealing at the connection between the protective component and the frame, thereby effectively preventing oil droplets from entering the interior of the protective component from the connection point between the protective component and the frame.

[0127] In this embodiment, the inner wall of the protective component is also provided with raised ribs, which can press the temperature sensing module against the inner side of the frame. This minimizes the gap between the temperature sensing module and the inner surface of the frame, and even if some oil droplets enter the interior of the protective component, the oil droplets will not enter the space between the temperature sensing module and the inner surface of the frame, preventing oil droplets from soaking into the filter and affecting the detection accuracy of the detection probe. In this embodiment, when the protective component is installed on the mounting bracket, the raised ribs can press the temperature sensing module tightly against the inner side of the panel. In addition, the raised ribs can also strengthen the structural strength of the protective component. In this embodiment, the raised ribs are cross-shaped; in other embodiments, the specific shape of the raised ribs is not limited, as long as they can press against the temperature sensing module.

[0128] In this embodiment, the upper wall of the protective component includes a first end and a second end. The first end is connected to the rear side wall, and the second end faces the frame. The upper wall tends to slope downwards or bend from the first end to the second end. In this embodiment, an arc surface is formed between the upper wall and the flange, which can guide oil droplets falling on the flange and prevent oil or water droplets from depositing between the flange and the panel and entering the protective component, thereby further improving the oil-blocking effect of the protective component. In other embodiments, the upper wall can also be an inclined plane, and the end of the upper wall connected to the flange is higher than the end connected to the rear side wall, so as to smoothly guide oil droplets or water droplets falling on the flange or the upper wall to the rear side wall and finally fall off the protective component, preventing oil or water droplets from depositing between the flange and the panel and entering the protective component.

[0129] Example 4

[0130] This embodiment provides a kitchen appliance, which is not limited to range hoods or integrated cooktops. This embodiment uses a range hood as an example. The working principle of the range hood in this embodiment is the same as in Embodiment 1, and the similarities will not be repeated here. This embodiment proposes a novel temperature sensing module 2 and mounting bracket 5, and the temperature sensing module 2 and mounting bracket 5 are connected in a completely different manner than in Embodiment 1, as detailed below:

[0131] like Figures 11-14As shown, the range hood includes two mounting brackets 5, which are spaced apart on the inner side of the panel 11. The temperature sensing module 2 includes a body 21 and elastic arms 24. The specific structure of the body 21 in this embodiment is the same as in Embodiment 1, and will not be described again here. Elastic arms 24 are provided on opposite sides of the body 21. The temperature sensing module 2 is located between the two mounting brackets 5, and the elastic arms 24 abut against the corresponding mounting brackets 5. When installing the temperature sensing module 2, the user presses the two elastic arms 24 of the temperature sensing module 2 to reduce the width dimension (the direction of the line connecting the two elastic arms 24), so that the temperature sensing module 2 can be placed between the two mounting brackets 5. Then, the user releases the two elastic arms 24, and the two elastic arms 24 move in the direction of restoring deformation under the action of their own elastic force, thereby pressing them tightly between the two mounting brackets 5. The process of installing the temperature sensing module 2 onto the mounting brackets 5 does not require the use of other tools, making installation convenient and efficient.

[0132] Specifically, such as Figure 11 and Figure 12 As shown, the mounting bracket 5 includes a vertically arranged connecting part 51 and a limiting plate 55. The connecting part 51 is arranged parallel to the panel 11 and is used to fix the mounting bracket 5 to the panel 11. The limiting plates 55 of the two mounting brackets 5 are arranged facing each other. After the two elastic arms 24 elastically deform in a direction closer to each other, the temperature sensing module 2 can be confined between the two limiting plates 55, thereby realizing the connection between the temperature sensing module 2 and the two mounting brackets 5.

[0133] In this embodiment, the two mounting brackets 5 are symmetrically arranged, and the two limiting plates 55 are positioned opposite each other on the left and right, respectively, and the temperature sensing module 2 can be installed between the two limiting plates 55 from top to bottom. In other embodiments, the temperature sensing module 2 can also be installed between the two limiting plates 55 from bottom to top, or from back to front, and no specific limitation is made here.

[0134] Optionally, in this embodiment, the two mounting brackets 5 are two independent components, each connected to the panel 11. In other embodiments, the two mounting brackets 5 can also be constructed as a single unit, which is then integrally mounted onto the panel 11. In this embodiment, the specific connection method between the connecting portion 51 of the mounting bracket 5 and the panel 11 is the same as in Embodiment 1, and will not be repeated here.

[0135] like Figure 11 and Figure 12 As shown, each of the two limiting plates 55 is provided with a snap-fit ​​hole 551. Figure 11 and Figure 13As shown, the elastic arm 24 includes an extension 241 and a latch 242. One end of the extension 241 is connected to the side wall of the main body 21, and the other end is located on one side of the corresponding side wall and spaced apart from it. The extension 241 can elastically deform towards the corresponding side wall. The latch 242 is located on the side of the extension 241 away from the side wall. Therefore, when the user stops pressing the elastic arm 24, the extension 241 drives the latch 242 to move away from the corresponding side wall of the main body 21, thereby causing the latch 242 to engage in the latching hole 551. Through the cooperation between the latch 242 and the latching hole 551, the position of the temperature sensing module 2 on the two mounting brackets 5 is further defined, thereby preventing the temperature sensing module 2 from wobbling.

[0136] like Figure 11 and Figure 12 As shown, the mounting bracket 5 also includes a support portion 52, which is connected to the limiting plate 55 and located at the entrance end where the temperature sensing module 2 extends between the two limiting plates 55, i.e., the upper end of the limiting plate 55 in this embodiment. Figure 11 and Figure 13 As shown, the elastic arm 24 also includes a stop portion 243, which is connected to the end of the extension portion 241 away from the side wall. The stop portions 243 of the two elastic arms 24 respectively abut against the corresponding bearing portions 52. Through the cooperation of the stop portion 243 and the bearing portion 52, on the one hand, the temperature sensing module 2 can be supported in the direction of extending into the two limiting plates 55, further improving the reliability of the connection of the temperature sensing module 2; on the other hand, the depth of the temperature sensing module 2 extending into the two limiting plates 55 can also be limited, thereby ensuring that the buckle 242 can be smoothly engaged into the buckle hole 551, making the installation process of the temperature sensing module 2 smoother. In this embodiment, the bearing portion 52 is respectively arranged perpendicular to the limiting plate 55 and the connecting portion 51. In other embodiments, the bearing portion 52 may also be arranged at an obtuse angle with the limiting plate 55. In this solution, the extension direction of the stop portion 243 of the elastic arm 24 is consistent with that of the bearing portion 52, thereby ensuring the temperature support between the stop portion 243 and the bearing portion 52.

[0137] In this embodiment, both the outer shell 211 and the elastic arm 24 are made of plastic and are integrally injection molded, which facilitates molding and ensures that the elastic arm 24 has a certain elastic deformation capability. As shown in Figures 21 and 22, the end of the extension 241 that connects to the main body 21 has an arc-shaped portion. Therefore, when the elastic edge undergoes elastic deformation, it is less likely to cause stress concentration in the elastic arm 24, thereby preventing the elastic arm 24 from breaking. It should be noted that the arc-shaped portion can be constructed as a circular arc or an arc with other trajectories, which is not limited here.

[0138] like Figure 11As shown, the buckle 242 is provided with a first guide slope 2421. The first guide slope 2421 is used to abut against the end of the limiting plate 55 when the temperature sensing module 2 is inserted between the two limiting plates 55, so as to guide the extension 241 to extend between the two limiting plates 55. This makes the process of the temperature sensing module 2 extending between the two limiting plates 55 smoother. In addition, the abutment between the limiting plate 55 and the first guide slope 2421 can assist in pressing the elastic arm 24, so as to appropriately reduce the pressure of the user on the elastic arm 24, further improving the convenience of installing the temperature sensing module 2. In this embodiment, the first guide slope 2421 is provided on the downward side of the buckle 242. When the temperature sensing module 2 is installed from top to bottom between the two limiting plates 55, the first guide slope 2421 abuts against the upper end of the limiting plate 55 to ensure that the temperature sensing module 2 is smoothly installed between the two limiting plates 55. The specific tilt angle and length of the first guide slope 2421 can be selected and set according to actual needs, and are not specifically limited here.

[0139] like Figure 1 As shown, the buckle 242 is provided with a second guide slope 2422, which guides the buckle 242 into the latching hole 551. In this embodiment, the second guide slope 2422 is located on the upward-facing side of the buckle 242. The second guide slope 2422 makes the cross-section of the end of the buckle 242 gradually increase from near the latching hole 551 to away from the latching hole 551, thus making it easier for the end of the buckle 242 to extend into the latching hole 551 and gradually extend completely into the latching hole 551. The setting of the second guide slope 2422 allows the buckle 242 to smoothly extend into the corresponding latching hole 551, ensuring the accuracy of the installation position of the temperature sensing module 2. Specifically, the inclination angle and length of the second guide slope 2422 can be selected and set according to actual needs, and are not specifically limited here.

[0140] like Figure 12 and Figure 13 As shown, the mounting bracket 5 also includes a first reinforcing plate 56 and a second reinforcing plate 57. The first reinforcing plate 56 is arranged parallel to and opposite to the bearing portion 52, and the second reinforcing plate 57 is arranged parallel to and opposite to the limiting plate 55. The arrangement of the first reinforcing plate 56 and the second reinforcing plate 57 makes the entire mounting bracket 5 structure more stable, thereby ensuring the reliability of the support for the temperature sensing module 2. Figure 14 As shown, a reinforcing rib 58 is also provided between the supporting part 52 and the connecting part 51, thereby further improving the structural strength of the mounting bracket 5. In other embodiments, reinforcing ribs 58 can be provided between adjacent plates of the mounting bracket 5, which is not specifically limited here.

[0141] It should be noted that in this embodiment, the range hood also includes a protective component 3. The protective component 3 is disposed inside the panel 11 and covers the temperature sensing module 2, thereby preventing oil droplets from other structures inside the kitchen appliance from falling onto the temperature sensing module 2, or preventing oil fumes from accumulating on the temperature sensing module 2. This prevents oil droplets from entering the temperature sensing module 2, ensuring that the detection probe maintains good detection accuracy and the electrical components function normally under long-term use, thus improving the detection accuracy and service life of the temperature sensing module 2. It should be noted that the specific structure of the protective component 3 in this embodiment can be any one of the embodiments in Embodiment 1, Embodiment 2, and Embodiment 3, and is not limited here.

[0142] Example 5

[0143] like Figures 15-21 As shown, this embodiment provides a temperature sensing module 2, which includes a housing, a detection probe, a circuit board 214, an inner support 216, and a first wire assembly 23. The electrical connection method between the detection probe, the circuit board 214, and the first wire assembly 23, and the specific principle of temperature detection by the temperature sensing module 2 in this embodiment are the same as in Embodiment 1, and the similarities will not be repeated here. The main differences between this embodiment and Embodiment 1 lie in the detailed structure of the housing, the sealing of the housing, and the sealing between the housing and the first wire assembly 23, as detailed below:

[0144] like Figures 15-16 As shown, the housing includes an outer shell 211 and a cover 212. The outer shell 211 includes a receiving cavity with a second opening 2119. The detection probe 213 and the circuit board 214 can be installed into the receiving cavity through the second opening 2119. The cover 212 is placed on the outer shell 211 and covers the second opening 2119, thereby protecting the detection probe 213 and the circuit board 214. In this embodiment, the temperature sensing module 2 forms an integral structure, which facilitates independent maintenance and replacement. One end of the first wire assembly 23 is electrically connected to the circuit board 214, and the other end extends from the detection probe 213 to facilitate electrical connection to the control module of the range hood.

[0145] like Figure 16 and Figure 17 As shown, the temperature sensing module 2 also includes an annular seal 25, which surrounds the outer periphery of the second opening 2119. The cover 212 and the outer shell 211 together hold the annular seal 25. By setting the annular seal 25, the gap between the cover 212 and the outer shell 211 can be well sealed, thereby preventing oil fumes from entering the interior from the connection between the cover 212 and the outer shell 211. This ensures that the temperature sensing module 2 can maintain better detection accuracy and also improves the service life of the temperature sensing module 2.

[0146] like Figure 16As shown, the outer casing 211 includes a base plate 2116 and sidewalls. The sidewalls surround the base plate 2116 and form a columnar structure with a second opening 2119 on one side. In this embodiment, the outer casing 211 is a quadrangular prism structure. In other embodiments, the outer casing 211 can also be a cylinder, a triangular prism, etc., which is not limited here. Further, the sidewalls of the outer casing 211 include a side peripheral plate 2111 and an outward protrusion 2112. The outward protrusion 2112 is connected to one end of the side peripheral plate 2111 near the second opening 2119 (i.e., the end away from the base plate 2116), and an annular seal 25 is disposed between the casing 212 and the outward protrusion 2112. By providing the outward protrusion 2112, the annular seal 25 can be reliably clamped, thereby ensuring good sealing between the outer casings 211 and the outer casings 211. An annular groove 2113 is provided on one of the sides of the protruding portion 2112 and the cover 212 facing each other. An annular seal 25 is disposed in the annular groove 2113 and sandwiched between the cover 212 and the protruding portion 2112. The annular groove 2113 provides good positioning for the annular seal 25, improving the assembly efficiency between the annular seal 25, the outer shell 211, and the cover 212, and preventing misalignment of the annular seal 25, thus improving the reliability of the seal. In this embodiment, the annular groove 2113 is located on the side of the protruding portion 2112 facing the cover 212. In other embodiments, the annular groove 2113 may be located on the side of the cover 212 facing the protruding portion 2112.

[0147] like Figures 16-18 As shown, the cover 212 includes a cover body 2121 and a flange 2122. The flange 2122 surrounds the outer periphery of the cover body 2121 and extends towards the outer shell 211, covering the outer side of the protrusion 2112. The flange 2122 covering the protrusion 2112 increases the length and tortuosity of the path for oil fumes or oil droplets to enter the shell, thereby further improving the sealing performance between the cover 212 and the outer shell 211. In this embodiment, the cover body 2121 and the flange 2122 are integrally injection molded, which is convenient for molding and ensures that the cover 212 itself does not have gaps, thus guaranteeing the sealing performance of the temperature sensing module 2.

[0148] like Figure 16As shown, a first step 2123 is provided on the inner wall of the flange 2122, and a second step 2114 is provided on the side of the outward protrusion 2112 facing the flange 2122. The first step 2123 and the second step 2114 are in a concave-convex fit. The fit between the first step 2123 and the second step 2114 further increases the length and crankshaft of the path for oil fumes or oil droplets to enter the housing, thereby further improving the sealing effect between the outer shell 211 and the cover 212. In this embodiment, the extension trajectory of the first step 2123 is consistent with the enclosing trajectory of the flange 2122, and the extension trajectory of the second step 2114 is consistent with the extension trajectory of the first step 2123, thereby ensuring a good sealing effect. Optionally, in this embodiment, the number of steps of the first step 2123 and the second step 2114 can be one, two, three, four, etc., and is not limited here.

[0149] like Figure 16 and Figure 18 As shown, the cover 212 also includes an annular baffle 2125 disposed on the cover body 2121. The annular baffle 2125 is inserted into the second opening 2119 and abuts against the inner side of the side wall of the outer shell 211. On the one hand, the annular baffle 2125 further increases the length and tortuosity of the path for external oil droplets or fumes to enter the shell, preventing oil droplets or fumes from entering through the gap between the cover 212 and the outer shell 211. On the other hand, an annular groove is formed between the annular baffle 2125 and the flange 2122, and the protrusion 2112 of the outer shell 211 can be confined in the annular groove, thereby improving the ease of installation between the outer shell 211 and the cover 212. In this embodiment, the annular baffle 2125 is integrally formed with the cover body 2121 and the flange 2122.

[0150] In another embodiment, such as Figure 19 As shown, the cover 212 also includes a hook portion 2124 formed at the end of the flange 2122 away from the cover body 2121, and the hook portion 2124 hooks with the outward protrusion 2112. By providing the hook portion 2124, not only can the difficulty of oil droplets or fumes entering the housing be increased, improving the sealing between the cover 212 and the outer shell 211, but the cover 212 can also be prevented from falling off the outer shell 211, ensuring a stable connection between the cover 212 and the outer shell 211. Optionally, the hook portion 2124 can be annular extending circumferentially along the cover 212, and the extension path of the hook portion 2124 is consistent with the surrounding path of the flange 2122. In other embodiments, the hook portion 2124 may also include a plurality of hook-shaped structures spaced apart along the surrounding path of the flange 2122, which is not limited here.

[0151] like Figure 16As shown, the outer shell 211 has a first positioning part 2115 disposed within the receiving cavity, and the cover 212 has a second positioning part 2126 disposed on the side facing the second opening 2119. The end of the first positioning part 2115 and the end of the second positioning part 2126 are in a concave-convex fit. Through the cooperation of the first positioning part 2115 and the second positioning part 2126, the fitting accuracy between the outer shell 211 and the cover 212 can be ensured, thereby ensuring good sealing between them. In this embodiment, as... Figure 16 As shown, the end of the first positioning part 2115 is provided with a slot 21151, and the end of the second positioning part 2126 is inserted into the slot 21151. Of course, in other embodiments, the end of the second positioning part 2126 may also be provided with a slot 21151, and the end of the first positioning part 2115 may be inserted into the slot 21151. In this embodiment, the outer shell 211 is provided with two first positioning parts 2115, and the cover 212 is provided with two corresponding second positioning parts 2126. Each first positioning part 2115 and one second positioning part 2126 are in a concave-convex fit. In other embodiments, the number of sets of first positioning parts 2115 and second positioning parts 2126 is not limited.

[0152] The temperature sensing module 2 also includes a locking member (not shown), which passes through the cover 212 and connects to the outer shell 211, thereby locking the outer shell 211 and the cover 212 together and ensuring the reliability of the connection between the cover 212 and the outer shell 211. Specifically, as shown... Figure 16 As shown, the cover 212 is provided with a locking hole 2127, and the outer shell 211 is provided with a countersunk hole 21152, which is a threaded hole. The locking element is a screw, which passes through the locking hole 2127 and is threadedly connected to the countersunk hole 21152 on the outer shell 211, making disassembly and assembly convenient. Optionally, the temperature sensing module 2 in this embodiment includes two locking elements. In other embodiments, the temperature sensing module 2 may also include three or more locking elements. The specific number can be flexibly set and is not limited here.

[0153] In this embodiment, the countersunk hole 21152 is disposed on the end face of the first positioning part 2115 (i.e., the bottom of the slot 21151), and the locking hole 2127 is disposed on the second positioning part 2126 and penetrates the cover 212. By disposing the locking hole 2127 and the countersunk hole 21152 on the first positioning part 2115 and the second positioning part 2126 respectively, the concave-convex fit structure between the first positioning part 2115 and the second positioning part 2126 effectively increases the tortuousness of the path through which external fumes enter the outer casing 211 from the locking hole 2127. In other words, the concave-convex fit of the first positioning part 2115 and the second positioning part 2126 not only positions the outer casing 211 and the cover 212 but also seals the mounting position of the locking component, further ensuring good sealing performance.

[0154] like Figure 16and Figure 17 As shown, a lead wire hole is formed between the outer casing 211 and the cover 212. The temperature sensing module 2 also includes a lead wire seal 26, which is sealed to the lead wire hole. The first wire assembly 23 passes through the lead wire seal 26. By setting the lead wire seal 26, the sealing effect between the first wire assembly 23 and the outer casing 211 can be improved, thereby preventing oil fumes from entering the interior of the outer casing 211 from the gap between the first wire assembly 23 and the outer casing 211. The lead wire seal 26 is made of rubber material, and its compressed position between the lead wire hole and the first wire assembly 23 ensures good sealing performance.

[0155] In one embodiment, such as Figure 16 and Figure 17 As shown, the side wall of the outer casing 211 has a first notch 2117 at the second opening 2119 end. The lead-out seal 26 is installed in the first notch 2117. When the casing cover 212 is placed on the outer casing 211, the lead-out seal 26 is pressed tightly within the first notch 2117. This improves the sealing performance of the lead-out position of the first wire assembly 23. The casing cover 212 has a first pressing boss 2129 on the side facing the second opening 2119. The first pressing boss 2129 cooperates with the first notch 2117 to form a lead-out hole. The first pressing boss 2129 presses the lead-out seal 26 tightly, thereby improving the sealing performance at the installation position of the lead-out seal 26. It should be noted that in this embodiment, due to the setting of the first notch 2117, the outward protrusion 2112 on the side wall of the outer casing 211 is not a closed ring, but a non-closed ring that is interrupted by the first notch 2117. Similarly, the flange 2122 and the annular retaining rib 2125 on the outer shell 211 are not closed rings, but non-closed rings that are broken by the first pressing boss 2129.

[0156] Specifically, such as Figure 16 and Figure 17As shown, the outlet seal 26 includes a first main body 261, which is a columnar structure. The first wire assembly 23 passes through the first main body 261, and the first main body 261 has a lead hole and is clamped in the lead hole, thereby ensuring the sealing of the first wire assembly 23. The outlet seal 26 also includes a first sealing part 262 and a second sealing part 263, which are constructed on the outer periphery of the first main body 261 and are spaced apart along the axial direction of the first main body 261. The first main body 261, the first sealing part 262, and the second sealing part 263 form a insertion groove, and the portion of the side wall of the outer shell 211 around the lead hole is inserted into the insertion groove. This further improves the sealing of the outlet position of the first wire assembly 23. Optionally, the outlet seal 26 and the first wire assembly 23 can be a separate structure. In other embodiments, the lead-out seal 26 may also be integrally formed with the outer insulation of the first wire assembly 23, which is not limited here. The first notch 2117 may be U-shaped, so that after the first notch 2117 and the first pressing boss 2129 are engaged, an approximately circular structure can be formed, which can then be tightly engaged with the columnar first main body 261. In other embodiments, the first notch 2117 may also be semi-circular, rectangular, etc., which is not limited here.

[0157] In another embodiment, such as Figure 20 and Figure 21 As shown, the edge of the cover 212 has a second notch 2128. The lead-out seal 26 is installed within the second notch 2128. When the cover 212 is placed on the outer casing 211, the lead-out seal 26 is pressed tightly within the second notch 2128, thereby ensuring the sealing at the lead-out position of the first wire assembly 23. The outer casing 211 has a second pressing boss 2118 on the end face of the side wall. The second pressing boss 2118 cooperates with the second notch 2128 to form a lead hole. The second pressing boss 2118 presses the lead-out seal 26 tightly, thereby improving the sealing at the installation position of the lead-out seal 26. It should be noted that in this embodiment, due to the setting of the second notch 2128, the flange 2122 and the annular retaining rib 2125 on the outer casing 211 are not closed rings, but non-closed rings interrupted by the second pressing boss 2118.

[0158] Specifically, such as Figure 20 and Figure 21As shown, the outlet seal 26 includes a second main body 264, which is a columnar structure. The first wire assembly 23 passes through the second main body 264, and the second main body 264 passes through a lead hole and is clamped in the lead hole, thereby ensuring the sealing of the first wire assembly 23. The outlet seal 26 also includes a third sealing part 265 and a fourth sealing part 266, which are constructed on the outer periphery of the second main body 264 and are spaced apart along the axial direction of the second main body 264. The second main body 264, the third sealing part 265, and the fourth sealing part 266 form a insertion groove, and the portion of the cover body 2121 of the cover 212 around the lead hole is inserted into the insertion groove. This further improves the sealing of the outlet position of the first wire assembly 23. Optionally, the outlet seal 26 and the first wire assembly 23 can be a separate structure. In other embodiments, the lead-out seal 26 may also be integrally formed with the outer insulation of the first wire assembly 23, which is not limited here. The second notch 2128 may be U-shaped, so that after the second notch 2128 and the second pressing boss 2118 are engaged, an approximately circular structure can be formed, which can then be tightly engaged with the columnar second main body 264. In other embodiments, the first notch 2117 may also be semi-circular, rectangular, etc., which is not limited here.
