Description

Technical Field

[0001] The present invention relates to the technical field of range hoods, and specifically provides a smoke sensor assembly for a range hood, a range hood, and an integrated stove. Background Art

[0002] A range hood is one of the essential kitchen appliances in modern families, which can suck away the oil fume generated during cooking and discharge it outdoors, thereby maintaining the indoor air quality.

[0003] Some range hoods are equipped with a fixed-frequency motor at the factory. Regardless of the size of the oil fume concentration, they always work in one working mode, and at most change the number of fan starts to cope with the change of the oil fume concentration, and the user needs to manually adjust it. The upgraded range hoods are mostly equipped with a variable-frequency motor, which can automatically adjust the fan speed according to the change of the oil fume concentration to achieve the purpose of reducing energy consumption. Such range hoods need to be equipped with a smoke sensor module. The smoke sensor module is a key module for detecting smoke and oil fume on the range hood, and it is installed at the smoke inlet of the air duct. However, the air duct structures and sizes of different models of range hoods may be different, and correspondingly, the smoke sensor modules also need to be designed with different sizes, resulting in poor installation versatility of the smoke sensor modules and unable to achieve modular installation.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above technical problems, that is, to solve at least the problem of poor installation versatility of the existing smoke sensor module.

[0006] In a first aspect, the present invention provides a smoke sensor assembly for a range hood, the smoke sensor assembly including: a smoke sensor module for detecting the smoke flowing through it; a connecting member, which includes a first connecting member and a second connecting member, the first connecting member and the second connecting member are pivotally connected through a pivot shaft, the smoke sensor module is connected to the first connecting member, a first connection point is provided at a position of the first connecting member away from the pivot shaft, a second connection point is provided at a position of the second connecting member away from the pivot shaft, and the smoke sensor assembly can be connected to the smoke sensor installation position of the range hood through the first connection point and the second connection point.

[0007] In some feasible embodiments of the above smoke sensor assembly for a range hood, in the installed state, the second connecting member is located below the first connecting member, the second connecting member includes a second base body, and further includes an oil receiving portion extending outward from the surface of the second base body.

[0008] In some feasible embodiments of the smoke sensing assembly for the range hood described above, the oil receiving part has a first diversion surface facing the smoke sensing module. The first diversion surface is a curved surface, and a convergence point is formed on the connection line between the oil receiving part and the second base.

[0009] In some feasible embodiments of the smoke sensing assembly for the range hood described above, through holes communicating with the upper and lower sides of the convergence point are formed on the second base, so that the oil liquid collected by the oil receiving part can flow downward through the through holes.

[0010] In some feasible embodiments of the smoke sensing assembly for the range hood described above, the oil receiving part has a second diversion surface facing away from the smoke sensing module. The second diversion surface faces the flowing direction of the smoke and is set as a streamlined curved surface capable of guiding the flow of the smoke.

[0011] In some feasible embodiments of the smoke sensing assembly for the range hood described above, the smoke sensing module includes a housing and components. The housing includes a base, the components are arranged on the base, and the base is detachably connected to the first connecting piece.

[0012] In some feasible embodiments of the smoke sensing assembly for the range hood described above, the base is snap - connected to the first connecting piece.

[0013] In some feasible embodiments of the smoke sensing assembly for the range hood described above, at least a part of the first connecting piece and / or the second connecting piece is set as a conformal structure of the smoke sensing installation position.

[0014] In a second aspect, the present invention further provides a range hood, which includes the smoke sensing assembly for the range hood according to any one of the foregoing technical solutions.

[0015] In a third aspect, the present invention further provides an integrated stove, which includes the range hood according to any one of the foregoing technical solutions.

[0016] The smoke sensor component provided by the present invention is configured by setting a connecting member, which includes a first connecting member and a second connecting member pivotally connected to each other. One of the two connection points between the connecting member and the smoke sensor installation position of the range hood is set on the first connecting member, and the other of the two connection points between the connecting member and the smoke sensor installation position is set on the second connecting member. In this way, when installing the smoke sensor module on the range hood, for range hood blowers of different sizes (the distances between the installation points of the smoke sensor installation positions are different for different sizes of range hood blowers), after fixing the first connection point to the blower housing, only the second connecting member needs to be swung relative to the first connecting member by a certain angle to align and fix the second connection point with the preset installation point on the blower housing. That is, the distance between the connection points can be adjusted by swinging the second connecting member relative to the first connecting member, so that the adjusted connecting member can adapt to the installation points of the smoke sensor installation position of the range hood, without setting different smoke sensor components or opening special installation holes for different sizes of blowers, improving the versatility of the smoke sensor component, facilitating modular installation, and having a simple and convenient installation method. The installed structure is stable and reliable, which can greatly reduce the development and manufacturing costs.

[0017] Further, an oil receiving part is provided on the second connecting member below the first connecting member, the surface of the oil receiving part facing the smoke sensor module is set as a curved surface, and a converging point is formed on the connection line between the oil receiving part and the second base, so that oil droplets can converge towards the converging point under the guidance of the diversion surface, realizing the functions of oil collection and splash prevention.

[0018] It can be understood that the first converging point should be located at the lowest and non-edge position of the oil receiving part. Therefore, to play a converging role, its edge should have a certain degree of warping.

[0019] Further, through holes communicating with the upper and lower sides of the converging point are formed on the second base, so that the oil liquid collected by the oil receiving part can flow down along the surface of the second base through the through holes and enter the oil collection area of the blower, thereby avoiding random dripping of oil droplets.

[0020] Further, by setting a second diversion surface on the oil receiving part and setting it as a streamline curved surface capable of guiding the flow of smoke, the direction of smoke flow can be better guided, avoiding the direct spraying of smoke on the components of the smoke sensor module, and achieving the purpose of protecting the smoke sensor module.

[0021] By detachably connecting the base of the outer shell of the smoke sensor module to the first connecting member, such as by snap connection, it is not only convenient for the assembly of the smoke sensor component, but also convenient for maintenance and replacement when the smoke sensor module fails. When replacing, only the smoke sensor module needs to be removed and a new one installed, without disassembling and assembling the entire smoke sensor component.

[0022] Further, by setting the first connecting member and / or the second connecting member into a conformal structure of the smoke detector installation position, the blockage of the smoke flow path by the smoke detector assembly can be minimized while ensuring the detection effect.

[0023] Those skilled in the art can understand that since the above-mentioned range hood or integrated range cooker is configured with the smoke detector assembly described in any one of the foregoing technical solutions, it has all the technical effects that can be obtained by the foregoing smoke detector assembly, which will not be elaborated herein.

[0049] The following describes the smoke sensor assembly provided by the present invention and the range hood equipped with the smoke sensor assembly with reference to the accompanying drawings. In the drawings, Figure 1 is a schematic structural diagram of a blower equipped with a smoke sensor assembly provided by an embodiment of the present invention; Figure 2 is an assembled structural diagram of the smoke sensor assembly provided by an embodiment of the present invention; Figure 3 is an exploded structural diagram of the smoke sensor assembly provided by an embodiment of the present invention from a first perspective; Figure 4 is an exploded structural diagram of the smoke sensor assembly provided by an embodiment of the present invention from a second perspective; Figure 5 is an oil receiving schematic diagram of the smoke sensor assembly provided by an embodiment of the present invention; Figure 6 is an assembled schematic diagram of the smoke sensor assembly when it is adapted to a blower of a first size provided by an embodiment of the present invention; Figure 7 is an assembled schematic diagram of the smoke sensor assembly when it is adapted to a blower of a second size provided by an embodiment of the present invention.

[0050] The range hood provided by the embodiment of the present invention is a side-inlet and top-outlet range hood, which includes a housing (not shown), a blower arranged in the housing, an oil net (not shown), etc. The blower is arranged in the air duct constructed by the housing. As Figure 1 shown in, the blower 1 includes a housing 11 and an impeller 12 arranged in the housing 11. The impeller 12 is connected to a motor (not shown). The middle part of the housing 11 has an opening with a circular contour, and this opening is the smoke inlet 111 of the blower 1. A smoke exhaust port 112 is formed at the top of the housing 11. A smoke sensor installation position 113 is arranged at a position of the housing 11 close to its smoke inlet 111. The smoke sensor installation position 113 is used to install the smoke sensor assembly 2, and it has two installation points to connect with the connection points of the smoke sensor assembly 2. It should be noted that in order to avoid damaging the blower 1 due to opening the smoke sensor installation holes, the installation points for installing the smoke sensor assembly 2 are all reuses of existing points. Therefore, the distance between these points depends on the size of the blower 1. For blowers 1 of different sizes, the linear distance between the two installation points on the smoke sensor installation position 113 is different.

[0051] Based on this, the embodiment of the present invention provides a smoke sensor assembly 2 that can adjust its own structure according to the existing installation points to improve the installation versatility of the smoke sensor assembly 2.

[0052] The smoke sensor component 2 provided by the embodiment of the present invention includes a smoke sensor module 22 and a connecting member 21. The smoke sensor module 22 is used to detect the smoke flowing through it, such as detecting the oil fume concentration, smoke concentration, etc. In this embodiment, the smoke sensor module 22 is an infrared smoke sensor module 22, and the infrared smoke sensor module 22 includes an infrared transmitting unit and an infrared receiving unit. In this embodiment, the infrared transmitting unit and the infrared receiving unit are located on the same side of the detection area. The infrared transmitting unit is used to emit infrared light to the area corresponding to the smoke inlet 111. When the smoke with oil fume particles passes through the infrared detection area, the oil fume particles will refract and reflect part of the infrared light, causing the infrared signal received by the infrared receiving unit to change, so as to sense the passing oil fume or steam; the more smoke passes through, the greater the amount of infrared light reflected back, and the greater the change in the infrared signal, so as to judge the amount and change of the oil fume. It should be noted that the smoke sensor module 22 is not limited to the infrared smoke sensor module 22, and there can be various implementation manners, as long as it can detect and sense the amount of oil fume passing through the smoke inlet 111.

[0053] In the embodiment of the present invention, the smoke sensor module 22 is connected to the smoke sensor installation position 113 through the connecting member 21.

[0054] Specifically, as Figures 2 to 4 shown, the connecting member provided by the embodiment of the present invention includes a first connecting member 211 and a second connecting member 212, and the first connecting member 211 and the second connecting member 212 are pivotally connected through a pivot shaft 213. As Figure 3 and Figure 4 shown, the first connecting member 211 includes a first base body 2111. The first base body 2111 has an arc-shaped swing arm structure, and an installation platform (not marked) is formed thereon for adapting to the smoke sensor module 22. One end of the first base body 2111 is constructed with a pivot connection point 21112 through which the pivot shaft 213 can pass. The pivot connection point 21112 is suitable for installing the pivot shaft 213. A fastener installation hole is provided at a position of the first connecting member 211 away from the pivot shaft 213, and the fastener installation hole serves as the first connection point 21111 of the first connecting member 211. Two buckles 2112 are further provided on the surface of the installation platform of the first base body 2111, and the buckles 2112 are used for snap connection with the smoke sensor module 22.

[0055] As Figure 2 and Figure 4As shown, the smoke sensor module 22 is connected to the first connecting member 211. The smoke sensor module 22 includes a shell 221 and components 222. The shell 221 includes a base 2211. The base 2211 is configured with a square groove 2212. The square groove 2212 is suitable for installing the components 222. The components 222 are arranged on the base 2211. The square groove 2212 corresponds to the through signal transmitting / receiving tube 2213. The components 222 can excite infrared light. The infrared light is emitted from the signal transmitting / receiving tube 2213, and after being reflected and refracted by the oil smoke particles, it enters the signal transmitting / receiving tube 2213 for further processing by the components 222. In this embodiment, the base 2211 of the shell 221 is snap-fitted to the first connecting member 211. Figure 4 As shown in , a card interface 22111 is formed on the base 2211, and a buckle 2112 is provided on the mounting platform. The buckle 2112 can directly pass through the card interface 22111 and be engaged with the upper surface of the base 2211 to fix the base 2211.

[0056] like Figure 2 and Figure 5 As shown, in the assembled state, the second connecting member 212 of this embodiment is located below the first connecting member 211, in order to further provide an oil receiving portion 2122 to receive and guide the oil droplets 3 dripping from the smoke sensor module 22 to prevent the oil droplets 3 from dripping randomly. Figure 2 As shown in , the second connecting member 212 includes a second base 2121 and an oil receiving portion 2122 extending outward from the surface of the second base 2121. The second base 2121 has a swing arm structure with a certain curvature. One end of the second base 2121 is provided with a pivot point adapted to the pivot connection point 21112 of the first connecting member 211, suitable for mounting the pivot shaft 213. A second connection point 21212 is provided on the second base 2121 at a position away from the pivot shaft 213. The smoke sensor assembly 2 can be connected to the smoke sensor mounting position 113 of the range hood via the first connection point 21111 and the second connection point 21212.

[0057] The oil receiving portion 2122 is formed by extending outward from the surface of the second base 2121. The oil receiving portion 2122 has a first guide surface facing the smoke sensor module 22 and a second guide surface facing away from the smoke sensor module 22. The first guide surface and the second guide surface are both curved surfaces. In this embodiment, the first guide surface and the second guide surface have the same shape, so that the oil receiving portion 2122 has a thin plate structure with uniform thickness. Figure 5As shown in the figure, the first diversion surface is used to receive the oil droplets 3 dripping from the signal transmitting / receiving tube 2213 of the smoke sensor module 22, and then guide the oil droplets 3 to flow downward and converge at the convergence point (not marked) of the first diversion surface. The convergence point is on the connection line between the oil receiving part 2122 and the second base 2121, and is located at the lowest point. The edge of the oil receiving part 2122 near the convergence point is warped upward to form a warped part 21221 for gathering the splashing oil droplets 3. As Figure 2 and Figure 5 shown, through holes 21211 communicating with the upper and lower sides of the convergence point are formed on the second base 2121, so that the oil liquid collected by the oil receiving part 2122 can be discharged downward through the through holes 21211 and finally enter the oil collecting area of the air duct. The flow path of the oil droplets 3 is as shown by the arrow in Figure 5 . By setting it in this way, the random splashing of the oil droplets 3 can be effectively prevented.

[0058] Continue to refer to Figure 5 . The second diversion surface faces the flowing direction of the smoke. Through simulation calculation, the second diversion surface is set as a streamline-shaped surface capable of guiding the flow of the smoke, so that the flowing smoke can avoid the components 222 of the smoke sensor module 22 as much as possible, which is beneficial to extending the service life of the smoke sensor module 22.

[0059] It should be noted that the second connecting member 212 can also be arranged above the first connecting member 211. In this case, the oil receiving part 2122 can be not configured. In addition, the shapes of the first diversion surface and the second diversion surface can also be different because their functions are different. For example, when the thickness of the oil receiving part 2122 is different and non-uniformly gradually changes, the shapes of the first diversion surface and the second diversion surface are different.

[0060] It can be understood that the number of the buckles 2112 on the installation platform of the first base 2111 is not limited to two, and can also be any appropriate number such as three, four, etc. In addition, in order to improve the installation stability, positioning or limiting structures can also be arranged on the installation platform.

[0061] Next, the installation principle of the smoke sensor assembly 2 provided by the embodiment of the present invention will be described in detail with reference to Figure 6 and Figure 7 .

[0062] As Figure 6 shown in the figure, Figure 6The straight-line distance between the installation points of the housing 11 of the fan 1 is 152 mm. When the first connection point 21111 of the connecting member is aligned with the first installation point 1131 on the smoke detector installation position 113 and fixed by fasteners, such as by screws, rivets, etc., and then the second connection point 21212 of the second connecting member 212 is aligned with the second installation point 1132 on the smoke detector installation position 113 and fixed by fasteners, the installation of the smoke detector assembly 2 on the fan 1 of the first size can be achieved. During this process, the second connecting member 212 swings relative to the first connecting member 211 to adapt the connecting member to the installation point. In the installed state, the angle between the emission direction of the infrared ray emitted by the smoke detector module 22 and the horizontal plane is 14°, which can cover most of the smoke flow path of the smoke inlet 111, so the reliability of the detection effect can be ensured.

[0063] As Figure 7 shown in Figure 7 the straight-line distance between the installation points of the housing 11 of the fan 1 is 144.5 mm. When the first connection point 21111 of the connecting member is aligned with the first installation point 1131 on the smoke detector installation position 113 and fixed by fasteners, such as by screws, rivets, etc., and then the second connection point 21212 of the second connecting member 212 is aligned with the second installation point 1132 on the smoke detector installation position 113 and fixed by fasteners, the installation of the smoke detector assembly 2 on the fan 1 of the second size can be achieved. During this process, the second connecting member 212 swings relative to the first connecting member 211 to adapt the connecting member to the installation point, and the swing angle is different from that during the installation on the fan 1 of the first size. In the installed state, the angle between the emission direction of the infrared ray emitted by the smoke detector module 22 and the horizontal plane is 20°, which can cover most of the smoke flow path of the smoke inlet 111, so the reliability of the detection effect can also be ensured.

[0064] When the smoke detector assembly 2 is installed on a third-size fan (not shown) with a straight-line distance of 137 mm between the installation points, in the installed state, the angle between the emission direction of the infrared ray emitted by the smoke detector module 22 and the horizontal plane is 25°.

[0065] In the embodiment of the present invention, the base parts of the first connecting member 211 and the second connecting member 212 are arranged in a shape following the shape of the smoke sensor installation position 113. Specifically, in the embodiment of the present invention, the smoke sensor assembly 2 is installed on the housing 11 of the fan 1 and near the smoke inlet 111 of the fan 1. Since the smoke sensor assembly 2 has a certain volume after assembly, installing it at the smoke inlet 111 will have a certain impact on the smoke flow path. By arranging the first connecting member 211 and the second connecting member 212 in a shape following the shape of the housing 11 at the smoke inlet 111, that is, the contour of the smoke inlet 111 is circular, the smoke sensor installation position 113 for installing the smoke sensor assembly 2 has the same radian. In the embodiment of the present invention, by designing the first connecting member 211 and the second connecting member 212 into a shape following the shape of the smoke sensor installation position 113, that is, as consistent with the radian of the smoke sensor installation position 113 as possible, after installation, the connecting member can well follow the contour of the smoke inlet 111, minimizing the blockage of the air inlet path as much as possible, ensuring effective detection while reducing the impact on the oil fume suction effect.

[0066] The smoke sensor assembly provided by the embodiment of the present invention can be well applied to fans of different sizes, can realize the adaptive adjustment of the smoke sensor assembly, so that the adjusted connecting member can be adapted to the installation point position of the smoke sensor installation position of the range hood, without setting different smoke sensor assemblies or opening special installation holes for fans of different sizes, improving the versatility of the smoke sensor assembly, facilitating modular installation, and the installation method is simple and convenient. The installed structure is stable and reliable, which can greatly reduce the development and manufacturing costs.

[0067] It should be noted that the size of the installation point position, the included angle degree between the infrared ray and the horizontal line, etc. in the above embodiments are only exemplary, for better explaining the technical solution of the present invention, and should not be construed as a limitation on the protection scope of the present invention. The above values can also be other reasonable values.

[0068] In order to further improve the installation stability of the smoke sensor assembly, installation point positions can also be added to the first connecting member.

[0069] So far, the technical solution of the present invention has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
