Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a temperature sensing component and a range hood. Background Technology

[0002] With increasing automation, existing household appliances (such as range hoods) are incorporating temperature sensors to control their operation. In these technologies, temperature sensors are typically fixed directly to a mounting plate. This requires creating a compliant structure on the mounting plate, making manufacturing relatively complex. If a snap-fit ​​method is used, the plate thickness must be measured beforehand to determine the slot position. However, this requires re-determining the slot position based on varying plate thicknesses, resulting in poor applicability. If adhesive bonding is used, the sensor risks detaching, impacting the user experience. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a temperature sensing component and a range hood, which effectively solves the problem of poor applicability of temperature sensing components.

[0004] The above-mentioned technical problems are solved by the following technical solutions:

[0005] A temperature sensing component, comprising:

[0006] The box body includes a top plate and a side wall extending downward along the bottom of the top plate, and the outer wall surface of the side wall is provided with external threads;

[0007] A nut is fitted onto the side wall, and the nut has an internal thread that matches the external thread;

[0008] A temperature sensing module is installed inside the box. The temperature sensing module includes a temperature sensing probe. A first through hole is provided on the top plate of the box, and the temperature sensing probe is disposed in the first through hole.

[0009] A cover plate, which is detachably installed at the bottom of the box.

[0010] Compared with the prior art, the temperature sensing component of this utility model has the following advantages: By providing external threads on the outer wall of the side wall of the housing, and then fitting a nut onto the side wall of the housing, an internal thread matching the external threads is provided on the inner wall of the nut. Through the engagement of the internal threads on the nut and the external threads on the side wall of the housing, the mounting plate of the household appliance can be clamped between the nut and the top plate of the housing, thereby fixing the temperature sensing component to the household appliance. Within the range of the external threads on the side wall of the housing, the temperature sensing component can be installed on mounting plates of different thicknesses by adjusting the nut. Only one opening to accommodate the housing needs to be made on the mounting plate; no matching connection structure is required, effectively improving the applicability of the temperature sensing component and simplifying installation. Furthermore, a first through hole is provided on the top plate of the housing, and the temperature sensing probe is installed in the first through hole, allowing the temperature sensing probe to directly contact the external environment, thereby ensuring the accuracy of temperature detection.

[0011] Furthermore, a cover plate is detachably connected to the bottom of the box. The cover plate can close the opening at the bottom of the box, thus placing the temperature sensing module in the housing space in a relatively enclosed space. If it is necessary to maintain or replace the temperature sensing module in the housing space, the cover plate can be opened to maintain or replace the temperature sensing module, thereby ensuring the efficiency of maintenance or replacement of the temperature sensing module.

[0012] In one embodiment, on the outer wall surface of the sidewall, the distance between the starting point of the external thread and the top plate is 0-1 mm;

[0013] And / or, the external thread extends from the starting point to the bottom of the sidewall.

[0014] In one embodiment, the temperature sensing module further includes a circuit board, which is installed inside the housing, and the temperature sensing probe is installed on the circuit board; the cover plate is provided with a second through hole that is positioned opposite to the cable position on the circuit board;

[0015] And / or, the second through hole extends to the edge of the cover plate.

[0016] In one embodiment, when the second through hole extends to the edge of the cover plate, the box body is provided with a first protrusion extending from the bottom end of the box body in a direction away from the box body. When the cover plate covers the box body, the first protrusion is disposed in the second through hole.

[0017] In one embodiment, a sealing structure is further included, which is disposed within the housing and covers the circuit board for sealing the circuit board;

[0018] Alternatively, the sealing structure may be located at the second through hole of the cover plate.

[0019] In one embodiment, a sealing gasket is also included, which is fitted onto the side wall of the housing and located between the nut and the top plate of the housing.

[0020] In one embodiment, a limiting post is also included, disposed inside the housing and extending obliquely downward toward the side wall. The outer peripheral surface of the limiting post abuts against the temperature sensing module to restrict the movement of the temperature sensing module.

[0021] In one embodiment, a protective cover is also included, detachably attached to the cover plate, for covering the box body.

[0022] In one embodiment, the protective cover includes a base plate with a buckle and a slot on the cover plate, the buckle and the slot cooperating to mount the protective cover on the cover plate.

[0023] In one embodiment, a clearance space is provided below the bottom plate of the protective cover for placing the cable of the temperature sensing module;

[0024] The protective cover is also provided with a cable outlet on its side for leading out the cable of the temperature sensing module.

[0025] On the other hand, this utility model also provides a range hood, comprising:

[0026] A smoke collection hood, wherein a mounting plate is provided on the smoke collection hood;

[0027] The temperature sensing component described above is detachably connected to the mounting plate.

[0028] Beneficial effects: By installing a mounting plate on the smoke hood and then engaging the internal thread of the nut with the external thread on the side wall of the housing, the mounting plate can be clamped between the nut and the top plate of the housing, thus fixing the temperature sensing component to the range hood. Within the range of the external thread on the side wall of the housing, the temperature sensing component can be installed on mounting plates of different thicknesses by adjusting the nut. Only one opening needs to be made on the mounting plate to accommodate the housing; no matching connection structure is required, effectively improving the applicability of the temperature sensing component and simplifying installation. Furthermore, a first through hole is provided on the top plate of the housing, and the temperature sensing probe is installed in the first through hole, allowing the temperature sensing probe to directly contact the external environment, thereby ensuring the accuracy of temperature detection.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] According to an embodiment of the present invention, in a first aspect, as follows: Figures 2 to 9 As shown, a temperature sensing component 10 is provided, including: a housing 11, including a top plate 115 and a side wall 114 extending downward along the bottom of the top plate 115, the outer wall surface of the side wall 114 is provided with external threads; a nut 12, sleeved on the side wall 114, the nut 12 is provided with internal threads that match the external threads; a temperature sensing module, installed in the housing 11, the temperature sensing module including a temperature sensing probe 151, the top plate 115 of the housing 11 is provided with a first through hole 111, the temperature sensing probe 151 is disposed in the first through hole 111; and a cover plate 13, the cover plate 13 being detachably installed at the bottom of the housing 11.

[0048] In this embodiment, the housing 11 serves as a support frame for the temperature sensing component 10, and a receiving space is formed within the housing 11. The housing 11 includes a top plate 115 and a side wall 114 extending downward along the bottom of the top plate 115. The receiving space is formed by the cooperation between the top plate 115 and the side wall 114. The outer wall surface of the side wall 114 of the housing 11 is provided with external threads, and a nut 12 is fitted onto the side wall 114 of the housing 11. The inner wall surface of the nut 12 is provided with internal threads that match the external threads. Through the cooperation between the internal threads on the nut 12 and the external threads on the side wall 114 of the housing 11, the nut 12 can move and be fixed on the housing 11, thereby clamping the mounting plate 20 of the household appliance between the nut 12 and the top plate 115 of the housing 11, and thus fixing the temperature sensing component 10 to the household appliance. Within the range of the external threads on the side wall 114 of the housing 11, the temperature sensing component 10 can be installed onto mounting plates 20 of different thicknesses by adjusting the nut 12. Only one opening needs to be made in the mounting plate to accommodate the housing 11; no matching connection structure is required, effectively improving the applicability of the temperature sensing component 10 and simplifying installation. The engagement of the external and internal threads allows the nut 12 to be tightened more thoroughly, reducing the gap between the nut 12 and the mounting plate 20, thus making the installation of the housing 11 more secure.

[0049] Furthermore, an opening is formed at the bottom of the housing 11, through which the temperature sensing module is installed into the housing 11. The temperature sensing module includes a temperature sensing probe 151, which detects the external ambient temperature to obtain a temperature signal, and then transmits the temperature signal to the control system of the household appliance to control the operation of the household appliance. A first through hole 111 is provided on the top plate 115 of the housing 11, and the temperature sensing probe 151 is installed in the first through hole 111, allowing the temperature sensing probe 151 to directly contact the external environment, thereby ensuring the accuracy of temperature detection.

[0050] A cover plate 13 is detachably connected to the bottom of the box body 11. The shape of the cover plate 13 matches the shape of the opening at the bottom of the box body 11. The opening at the bottom of the box body 11 can be closed by the cover plate 13, so that the temperature sensing module in the housing space is in a relatively closed space. If it is necessary to maintain or replace the temperature sensing module in the housing space, the cover plate 13 can be opened to maintain or replace the temperature sensing module, thereby ensuring the efficiency of maintenance or replacement of the temperature sensing module.

[0051] In other possible implementations, a filter is also provided on the first through hole 111 to prevent the temperature sensor 151 from being contaminated.

[0052] In one embodiment, the distance between the starting point of the external thread and the top plate 115 on the outer wall surface of the side wall 114 is 0-1 mm.

[0053] In this embodiment, the distance between the starting point of the external thread and the top plate 115 can be 0, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc., and can be set according to actual usage requirements without specific limitations. By reasonably setting the distance between the starting point of the external thread and the top plate 115, even when the mounting plate 20 is relatively thin, the temperature sensing component 10 can be installed on the mounting plate 20 of the household appliance by the internal thread on the inner wall of the nut 12 engaging with the external thread on the outer wall of the side wall.

[0054] Furthermore, the external thread extends from the starting point to the bottom of the side wall 114. By providing external threads from the starting point to the bottom of the side wall 114, the temperature sensing component 10 can be adapted to mounting plates 20 of greater thickness within the limited dimensions of the housing 11. For example, when two or three mounting plates 20 are stacked, the temperature sensing component 10 can also be installed on household appliances through the engagement of the nut 12 with the top plate 115. It is understood that when the distance between the starting point of the external thread and the top plate 115 is 0, it indicates that the external thread is provided from the lower surface of the top plate 115 to the bottom of the side wall, so that the external thread covers the side wall of the housing 11; when the distance between the starting point of the external thread and the top plate 115 is 1 mm, it indicates that no external thread is provided in the 1 mm distance from the lower surface of the top plate 115 to the starting point.

[0055] like Figure 4 , Figures 7 to 9 As shown, in one embodiment, the temperature sensing module further includes a circuit board 15, which is installed inside the housing 11, and a temperature sensing probe 151 is installed on the circuit board 15; the cover plate 13 is provided with a second through hole 131 that is positioned opposite to the cable 152 on the circuit board 15.

[0056] In this embodiment, the temperature sensing module also includes a circuit board 15, which is installed in the housing space of the box 11. The temperature sensing probe 151 is installed on the circuit board 15. The temperature sensing probe 151 detects the external ambient temperature to obtain a temperature signal, and then transmits the temperature signal to the circuit board 15. The circuit board 15 processes the temperature signal and then transmits the processing result to the control system of the home appliance to control the operation of the home appliance.

[0057] like Figure 7 As shown, a second through hole 131 is provided on the cover plate 13, and the position of the second through hole 131 is set opposite to the position of the cable 152 on the circuit board 15. This is used to lead out the cable 152 on the circuit board 15, so that the cable 152 on the circuit board 15 can be led out from the second through hole 131, thereby reducing the pulling of the cable 152 and also reducing the risk of the cover plate 13 being pulled off by the cable 152.

[0058] Furthermore, the second through hole 131 extends to the edge of the cover plate 13. By extending the second through hole 131 to the edge of the cover plate 13, the second through hole 131 is connected to the external space; at this time, the cable 152 can be connected to the circuit board 15 first, and then the cover plate 13 can be installed on the housing 11, and the cable 152 can be passed through the edge of the cover plate 13 and placed in the second through hole 131. Compared with a through hole that is closed on the periphery, it is easier to process and assemble the temperature sensing component 10.

[0059] In one embodiment, when the second through hole 131 extends to the edge of the cover plate 13, the box body 11 is provided with a first protrusion 113 extending from the bottom end of the box body 11 in a direction away from the box body 11. When the cover plate 13 covers the box body 11, the first protrusion 113 is disposed in the second through hole 131.

[0060] In this embodiment, as Figure 9 As shown, when the second through hole 131 extends to the edge of the cover plate 13, a first protrusion 113 is provided on the box body 11 extending from the bottom end of the box body 11 in a direction away from the box body 11. The first protrusion 113 has a positioning function. When the second through hole 131 extends to the edge of the cover plate 13 and the cover plate 13 covers the box body 11, the second through hole 131 is aligned with the first protrusion 113, so that the first protrusion 113 is set in the second through hole 131. Thus, through the cooperation of the first protrusion 113 and the second through hole 131, the cover plate 13 is accurately installed on the box body 11. Moreover, after the cover plate 13 is installed on the box body 11, the first protrusion 113 also has a limiting function to prevent the cover plate 13 from rotating under the pull of the cable 152 after it is installed on the box body 11, so as to avoid the cover plate 13 from falling off the box body 11.

[0061] In one embodiment, the cover plate 13 is provided with a first flange extending from the surface of the cover plate 13 in a direction away from the cover plate 13, and the first flange 132 is provided with a first opening 1321, which matches the first protrusion 113.

[0062] In this embodiment, a first opening 1321 is provided on the first flange 132, the first opening 1321 penetrates the first flange 132 and communicates with the second through hole 131. When the cover plate 13 is installed on the box body 11, the first opening 1321 is aligned with the first protrusion 113, so that the cover plate 13 is accurately installed on the box body 11. After the cover plate 13 is installed on the box body 11, the first protrusion 113 can also prevent the cover plate 13 from rotating under the pull of the cable 152 after it is installed on the box body 11, so as to avoid the cover plate 13 from falling off the box body 11.

[0063] In one embodiment, such as Figure 4 , Figure 7 and Figure 8 As shown, the first flange 132 is also provided with multiple snap-fit ​​parts 1322, and the inner wall of the box body 11 is provided with multiple second protrusions 112. The snap-fit ​​parts 1322 correspond one-to-one with the second protrusions 112. The cover plate 13 is detachably connected to the box body 11 through the cooperation of the snap-fit ​​parts 1322 and the second protrusions 112.

[0064] In this embodiment, the first flange 132 is provided with a plurality of snap-fit ​​portions 1322, which are spaced apart along the outer periphery of the first flange 132. Each snap-fit ​​portion 1322 can be a protrusion extending from the sidewall 114 of the first flange 132 away from the first flange 132. A plurality of second protrusions 112 are provided on the inner wall of the box body 11, which are spaced apart along the inner wall of the box body 11 and correspond one-to-one with the snap-fit ​​portions 1322. When the cover plate 13 is installed on the box body 11, the first opening 1321 is aligned with the first protrusion 113, and then the first flange 132 of the cover plate 13 is forcefully pushed into the receiving space of the box body 11. This causes the protrusion on the first flange 132 to engage with the first protrusion 113 inside the box body 11, thereby snapping the cover plate 13 onto the box body 11. This eliminates the need for screws to fix the cover plate 13 to the box body 11, making installation simple and convenient.

[0065] In one embodiment, a sealing structure is also included, which is disposed inside the housing 11 and covers the circuit board 15 for sealing the circuit board 15; or, the sealing structure is disposed at the second through hole 131 of the cover plate 13.

[0066] In this embodiment, the sealing structure can be a sealant. After the circuit board 15 is installed into the receiving space of the housing 11, the sealant is poured into the receiving space and the sealant covers the circuit board 15, thereby preventing contaminants from entering the receiving space and avoiding contamination of the circuit board 15, so as to increase the service life of the temperature sensing component 10.

[0067] In another embodiment, a sealing structure can also be provided at the second through hole 131 of the cover plate 13. By sealing the second through hole 131 with the sealing structure, contaminants can also be prevented from entering the housing space of the box 11, thereby avoiding contamination of the circuit board 15.

[0068] In other possible implementations, the sealing structure can also be a flexible sealing material such as foamed rubber, thereby ensuring that the circuit board 15 can be effectively sealed to prevent the circuit board 15 from being contaminated.

[0069] like Figure 3 As shown, in one embodiment, a sealing gasket 14 is also included, which is fitted onto the side wall 114 of the housing 11 and located between the nut 12 and the top plate 115 of the housing 11.

[0070] In this embodiment, the sealing gasket 14 is sleeved on the side wall 114 of the box body 11 and located between the nut 12 and the top plate 115 of the box body 11. When the box body 11 is installed on the mounting plate 20, one side of the sealing gasket 14 abuts against the nut 12 and the other side abuts against the mounting plate 20. This allows the sealing gasket 14 to seal the connection between the box body 11 and the mounting plate 20, preventing oil from flowing to the outside through the connection between the box body 11 and the mounting plate 20.

[0071] like Figure 8 As shown, in one embodiment, a limiting structure is also included, which is disposed inside the housing 11 and extends obliquely from top to bottom toward the side wall 114. The outer peripheral surface of the limiting post 16 abuts against the temperature sensing module to limit the movement of the temperature sensing module.

[0072] In this embodiment, multiple limiting posts 16 can be provided, all of which are disposed on the top plate 115 of the housing 11. These limiting posts 16 are inclined downwards towards the side wall 114. It is understood that in this embodiment, along the vertical direction, one end of each limiting post 16 is fixed to the top plate 115, and the other end is positioned near or abuts against the inner wall surface of the side wall 114. The diameter of the opening formed by the multiple limiting posts 16 gradually increases from the top plate 115 away from it. When the circuit board 15 is installed into the receiving space of the housing 11, pressing the circuit board 15 causes it to gradually move from the larger diameter opening towards the top plate 115 until it abuts against the top plate 115. At this point, the outer peripheral surfaces of the multiple limiting posts 16 abut against the circuit board 15, thereby restricting the movement of the circuit board 15 within the receiving space and preventing displacement during use.

[0073] In other possible implementations, the limiting structure can be a limiting buckle or a limiting protrusion. When the circuit board 15 is installed into the receiving space of the box 11, the limiting buckle or the limiting protrusion abuts against one side of the circuit board 15, so that the other side of the circuit board 15 is in close contact with the top plate 115 of the box 11, thereby preventing the circuit board 15 from moving within the receiving space of the box 11.

[0074] In other possible implementations, the side wall 114 is provided with a straight edge, that is, a straight structure extending axially on the side wall 114, making a local area of ​​the side wall 114 planar. This straight edge extends from the bottom to the top of the side wall 114. When a straight edge is provided on the side wall 114 of the box body 11, the shapes of the sealing gasket 14, the circuit board 15, and the cover plate 13 are all set to match the side wall 114 of the box body 11, so that the box body 11, the sealing gasket 14, the circuit board 15, and the cover plate 13 can be better connected together. At this time, the limiting structure can be set on the straight edge, so that the limiting structure can better realize the limiting function and facilitate the installation of the limiting structure.

[0075] like Figures 10 to 13 As shown, in one embodiment, a protective cover 30 is also included, which is detachably connected to the cover plate 13 for covering the box body 11.

[0076] In this embodiment, by installing a protective cover 30 on the cover plate 13, when the box body 11 is installed on the mounting plate 20 of the household appliance, one end of the protective cover 30 abuts against the mounting plate 20, thereby covering the box body 11 and preventing the external threads on the outer wall surface 114 of the box body 11 from being contaminated. Taking the range hood 1 as an example, when the temperature sensing component 10 is installed on the mounting plate 20 of the range hood 1, oil fumes and moisture will form oil droplets on the external threads of the box body 11. After prolonged use, the oil droplets may flow along the gap between the external and internal threads to the installation opening of the box body 11 and drip from the opening on the mounting plate 20 onto the stove, resulting in oil dripping and affecting the user experience. By covering the outside of the box body 11 with a protective cover 30, the condensation of oil fumes and moisture on the external threads can be effectively prevented, thereby avoiding oil dripping and improving the user experience of the range hood 1.

[0077] like Figure 11 and Figure 13 As shown, in one embodiment, the protective cover 30 includes a base plate 31, on which a buckle 311 is provided, and on the cover plate 13, a slot 133 is provided. The buckle 311 and the slot 133 cooperate to allow the protective cover 30 to be installed on the cover plate 13.

[0078] In this embodiment, the base plate 31 of the protective cover 30 is provided with a buckle 311, which is located inside the protective cover 30; the cover plate 13 is provided with a slot 133, and the buckle 311 corresponds to the slot 133. When the protective cover 30 needs to be installed on the cover plate 13, the buckle 311 on the protective cover 30 is aligned with the slot 133 on the cover plate 13, so that the buckle 311 extends into the receiving space of the housing 11 and is engaged with the cover plate 13, thereby realizing the engagement of the buckle 311 and the slot 133, so that the protective cover 30 can be securely and conveniently connected to the cover plate 13 and will not easily separate during normal use. Moreover, by providing a buckle 311 on the base plate 31 instead of a slot 133 on the base plate 31, contaminants can be prevented from entering the interior of the protective cover 30 from the slot 133, thereby avoiding contamination of the external threads by contaminants.

[0079] In one embodiment, a clearance space 33 is provided below the bottom plate 31 of the protective cover 30 for placing the cable 152 of the temperature sensing module; a wire outlet hole 32 is also provided on the side of the protective cover 30 for leading out the cable 152 of the temperature sensing module.

[0080] To ensure a secure installation of the protective cover 30, the distance between the installed top plate 115 and bottom plate 31 is typically small, making it difficult for the cable 152 to pass through. Therefore, in this embodiment, a clearance 33 is provided below the bottom plate 31 of the protective cover 30, corresponding to the second through hole 131. When the cable 152 of the circuit board 15 is led out from the second through hole 131, it can be placed in the clearance 33, overcoming the problem of the cable 152 being difficult to pass through. Simultaneously, a cable exit hole 32 is provided on the side of the protective cover 30, allowing the cable 152 at the clearance 33 to be led out from the cable exit hole 32 on the protective cover 30, thereby ensuring that the cable 152 of the circuit board 15 can be normally connected to other components.

[0081] Secondly, such as Figure 1 As shown, this utility model also provides a range hood 1, including: a smoke collection hood 100, on which an installation plate 20 is provided; and a temperature sensing component 10, which is detachably connected to the installation plate 20.

[0082] In this embodiment, by setting a mounting plate 20 on the smoke hood 100, and by engaging the internal thread of the nut 12 with the external thread on the side wall of the box 11, the mounting plate 20 on the smoke hood 100 can be clamped between the nut 12 and the top plate 115 of the box 11, thereby fixing the temperature sensing component 10 to the range hood 1. Within the range of the external thread on the side wall of the box, the temperature sensing component 10 can be installed on mounting plates 20 of different thicknesses by adjusting the nut 12. Moreover, only an opening for accommodating the box 11 needs to be made in the mounting plate 20, without the need for a matching connection structure for the box 11, which effectively improves the applicability of the temperature sensing component 10 and simplifies installation. Furthermore, a first through hole 111 is provided in the top plate 115 of the box 11, and the temperature sensing probe 151 is installed in the first through hole 111, so that the temperature sensing probe 151 can directly contact the external environment, thereby ensuring the accuracy of temperature detection.

[0083] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0084] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
