Description

Technical Field

[0001] The utility model relates to the technical field related to range hoods, in particular to a hinge cleaning structure and a range hood. Background Art

[0002] Close-suction range hoods have become the mainstream in the market due to their powerful exhaust effect.

[0003] However, most of the close-suction range hoods require the smoke baffle to be pushed open by a hinge. Therefore, when the smoke baffle is opened, the hinge is exposed. The hinge is in a relatively harsh oil fume environment during the operation of the range hood. After the range hood has been working for a long time, the grease in the oil fume will condense on the hinge. When the gathered grease accumulates to a certain extent, there is a possibility of dripping, thus affecting the consumer's experience. Utility Model Content

[0004] Based on this, it is necessary to provide a hinge cleaning structure and a range hood that can prevent grease from condensing on the hinges to address the problem that grease is easily condensed and dripped on the hinges of the current range hoods.

[0005] The present application first provides a hinge cleaning structure, comprising a shell, a hinge, a telescopic rod and a baffle, wherein the baffle is fixed to the hinge, the hinge is hinged to the shell, one end of the telescopic rod is hinged to the inside of the shell, and the other end passes through the shell to be hinged to the hinge.

[0006] The shell is provided with a cleaning hole corresponding to the hinge, and the shell is also fixed with a plurality of flexible cleaning members corresponding to the cleaning holes; when the baffle is closed, the hinge is at least partially inserted into the shell through the cleaning hole, and the flexible cleaning members abut against the hinge.

[0007] In one embodiment, a flexible cleaning plate covering the cleaning hole is fixed to the inner wall of the cleaning hole, and the flexible cleaning plate is provided with a first dividing slit extending along its own length direction, and a plurality of second dividing slits extending across the first dividing slit are provided parallel to its own length direction to form a plurality of flexible cleaning members.

[0008] In one embodiment, the first dividing slit is located at the center of the flexible cleaning plate along the width direction, and the hinge corresponds to the first dividing slit.

[0009] In one embodiment, the flexible cleaning member is made of a water-repellent and oil-repellent material, or the outer surface of the flexible cleaning member has a water-repellent and oil-repellent layer.

[0010] In one embodiment, the telescopic rod passes through the cleaning hole.

[0011] In one embodiment, the hinge cleaning structure also includes a controller and a detection resistor, wherein the detection resistor is fixed to the hinge and electrically connected to the controller so that the actual resistance value of the control resistor can be detected by the controller and compared with a preset resistance value; the controller is also electrically connected to the telescopic rod to control the extension and retraction of the telescopic rod.

[0012] In one of the embodiments, when the baffle is fully opened, the detection resistor is located at the bottom of the hinge.

[0013] In one embodiment, the detection resistor is in a strip shape, and the electrical connection positions of the detection resistor are located at two ends along the length direction of the detection resistor.

[0014] In one of the embodiments, the bottom of the hinge and the detection resistor are both arc-shaped, and when the baffle is fully opened, the lowest point of the detection resistor is located in the middle position along its own length direction.

[0015] A second aspect of the present application provides a range hood comprising the above-mentioned hinge cleaning structure.

[0026] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides a hinge cleaning structure, including a shell 10, a hinge 20, a telescopic rod 30 and a baffle 40, the baffle 40 is fixed to the hinge 20, the hinge 20 is hinged to the shell 10, one end of the telescopic rod 30 is hinged to the inside of the shell 10, and the other end passes through the shell 10 to be hinged to the hinge 20, the shell 10 is provided with a cleaning hole corresponding to the hinge 20, and the shell 10 is also fixed with a plurality of flexible cleaning members 113 corresponding to the cleaning holes; when the baffle 40 is closed, the hinge 20 is at least partially inserted into the shell 10 through the cleaning hole, and the flexible cleaning member 113 is against the hinge 20.

[0027] In the present application, a cleaning hole corresponding to the hinge 20 is opened on the shell 10, and a flexible cleaning member 113 corresponding to the cleaning hole is set, so that when the baffle 40 is opened or closed, the hinge 20 passes through the cleaning hole and can contact the flexible cleaning member 113, so that the grease and oil stains on the surface of the hinge 20 can be cleaned by the flexible cleaning member 113, thereby avoiding the accumulation and dripping of grease and improving the user experience.

[0028] Specifically, the flexible cleaning member 113 corresponds to the cleaning hole. The flexible cleaning member 113 can be fixed on the inner wall of the cleaning hole, or the flexible cleaning member 113 can be fixed at other positions of the shell 10 and extend into the cleaning hole. As long as the hinge 20 is inserted into the shell 10 through the cleaning hole, the flexible cleaning member 113 can be against the hinge 20 and complete the cleaning of the hinge 20.

[0029] Please refer to Figure 2 As shown, in some embodiments, a flexible cleaning plate 11 covering the cleaning hole is fixed to the inner wall of the cleaning hole, and the flexible cleaning plate 11 is provided with a first dividing slit 111 extending along its own length direction, and a plurality of second dividing slits 112 extending across the first dividing slit are provided parallel to its own length direction to form a plurality of flexible cleaning members 113.

[0030] Please refer to Figure 2As shown, in some embodiments, the first dividing seam 111 is located at the center of the flexible cleaning plate 11 along the width direction, and the hinge 20 corresponds to the first dividing seam 111, so that the flexible cleaning members 113 located on both sides of the first dividing seam 111 can fully and evenly clean the hinge 20.

[0031] In some embodiments, the flexible cleaning member 113 is made of a water-repellent and oil-repellent material, or the outer surface of the flexible cleaning member 113 has a water-repellent and oil-repellent layer.

[0032] Please refer to Figure 2 As shown, in some embodiments, the telescopic rod 30 passes through a cleaning hole, so that the flexible cleaning member 113 can also clean the telescopic rod 30 to prevent oil from condensing and adhering to the telescopic rod 30 .

[0033] Please refer to Figure 2 As shown, in some embodiments, the hinge cleaning structure also includes a controller and a detection resistor 21. The detection resistor 21 is fixed to the hinge 20 and electrically connected to the controller so that the actual resistance value of the detection resistor 21 can be detected by the controller and compared with the preset resistance value; the controller is also electrically connected to the telescopic rod 30 to control the extension and retraction of the telescopic rod 30.

[0034] Since the oil droplets formed by the condensation of oil smoke absorbed by the range hood are essentially a mixture of grease, water, salt and other substances, and have a certain conductivity, when oil droplets adhere to the surface of the detection resistor 21, the resistance value of the detection resistor 21 will change, that is, the amount of oil attached to the detection resistor 21 can be judged by the actual resistance value of the detection resistor 21.

[0035] Specifically, the more grease mixture there is on the surface of the detection resistor 21, the stronger the conductivity is, and the smaller the actual resistance value is; conversely, the less grease mixture there is, the greater the actual resistance value of the detection resistor 21 is; and the preset resistance value is a preset value calibrated according to actual needs. When the actual resistance value is less than or equal to the preset resistance value, it means that oil is condensed and gathered on the hinge 20 at this time, and the hinge 20 needs to be cleaned;

[0036] In the present application, when the controller detects that the actual resistance value is less than or equal to the preset resistance value, the controller controls the telescopic rod 30 to start, thereby driving the baffle 40 to close and then open, and the hinge 20 is cleaned through the flexible cleaning member 113 in the cleaning hole to achieve the effect of automatically cleaning the hinge 20.

[0037] More specifically, assuming that the resistance value of the detection resistor 21 is R when the oil drops, the preset resistance value can be set to R. When the controller detects that the actual resistance value is greater than or equal to R, the controller controls the telescopic rod 30 to retract and clean the hinge 20. After the controller detects that the actual resistance value of the detection resistor 21 is greater than or equal to 2R, it means that the cleaning is completed. The controller controls the telescopic rod 30 to extend until the baffle 40 is fully opened.

[0038] Of course, the resistance value representing the completion of cleaning can also be adjusted according to actual needs, and this application does not make any further limitations here.

[0039] In some other embodiments, the amount of oil attached to the detection resistor 21 may also be determined based on the output voltage of the detection resistor 21 , and the controller is used to detect the actual output voltage of the detection resistor 21 and compare it with a preset voltage.

[0040] In some embodiments, the sense resistor 21 is a sensing pad with exposed copper traces.

[0041] Please refer to Figure 2 As shown, in some embodiments, when the baffle 40 is fully opened, the detection resistor 21 is located at the bottom of the hinge 20, and the oil condensed on the hinge 20 will gather to the bottom of the hinge 20 under the action of its own weight. Therefore, setting the detection resistor 21 at the bottom of the hinge 20 can directly detect the amount of oil gathered.

[0042] Please refer to Figure 2 As shown, in some embodiments, the detection resistor 21 is in a bar shape, and the electrical connection positions of the detection resistor 21 are located at both ends along its own length direction, so that when the oil condenses on the detection resistor 21, the resistance change of the detection resistor 21 is more obvious, thereby being able to more accurately detect the resistance change of the detection resistor 21.

[0043] Please refer to Figure 2 As shown, in some embodiments, the bottom of the hinge 20 and the detection resistor 21 are both arc-shaped. When the baffle 40 is fully opened, the lowest point of the detection resistor 21 is located in the middle position along its own length direction; so that the grease at both ends of the detection resistor 21 can converge to the lowest point, the resistance value of the detection resistor 21 changes more obviously, and the detection sensitivity to grease adhesion is higher, avoiding the occurrence of oil dripping due to uncleaned oil stains.

[0044] In some other embodiments, the detection resistor 21 may also be in other shapes, such as two inclined planes with the apex in the middle, etc., as long as its lowest point is located in the middle position along its own length direction. This application does not give examples one by one here.

[0045] A second aspect of the present application provides a range hood comprising the above-mentioned hinge cleaning structure.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
