Description

Technical Field

[0001] The utility model relates to an oil fume purification device, in particular to an installation structure of a gesture sensing module and an oil fume extractor applying the installation structure. Background Art

[0002] As an essential kitchen appliance in every household, the oil fume extractor works by sucking oil fume from the air inlet through an impeller rotating at high speed in the volute, filtering the oil fume by the impeller, and discharging the filtered oil fume from the air outlet to complete the purification of kitchen air. A reasonable air inlet setting is beneficial to improving the oil fume suction effect, reducing the escape of oil fume, and improving the kitchen air quality.

[0003] For a lifting oil fume extractor that needs to meet the requirement of fully enclosing the cabinet, the oil fume extractor is generally lowered by a gesture function module arranged at the bottom of the smoke collecting hood, so that the touch switch on the front side of the oil fume extractor is lowered to a state where it can be controlled by the user. For example, a hidden oil fume extractor disclosed in a Chinese patent with the application number 202321037545.0.

[0004] Considering the working requirements of the gesture module, an infrared window structure corresponding to the position of the gesture module emission window is provided, and the installation surface corresponding to the window is required to be made of a transparent material or hollowed out to ensure the normal use of the function. For a gesture module provided with an infrared window, currently, it is usually fixed detachably in a manner similar to that of a lighting lamp by a snap-in slot from bottom to top; or a bracket (welded or directly stretched out) is provided on the installation base surface to fix the gesture module from top to bottom. For example, a gesture sensing switch and an oil fume extractor applying the gesture sensing switch disclosed in a Chinese patent with the application number 202121836023.8 by the applicant.

[0005] For the scheme of detachably fixing the overall module from bottom to top, it will directly result in an obvious installation gap around the installation surface, and it is difficult to achieve complete color unity between the installation surface and the gesture module due to factors such as differences in assembly materials, which affects the delicacy of the bottom surface of the smoke collecting hood. At the same time, the increase in cleaning dead corners also increases the cleaning difficulty. For the welding or direct stretching scheme, it will also damage the delicacy of the bottom surface of the smoke collecting hood, and the cost of welding and other processes is relatively high.

[0006] In addition, for the existing integrated structure of the boss and the bracket, during the actual installation process: if a relatively small installation gap is retained, due to the assembly error between the parts of the gesture module itself, the installation error of the gesture module on the installation surface, and the error of the installation surface opening itself, it may cause a situation where installation is impossible; when the set gap is relatively large, it will lead to a relatively large installation gap and uneven installation gaps caused by the relative deviation of the infrared-transmitting boss and the installation hole position. Whether it is a relatively large gap or a skewed gap, on the one hand, it affects the delicacy of the product itself, and at the same time, the relatively large gap creates more sanitary dead corners at the gap, increasing the cleaning difficulty for users. Summary of the Invention

[0035] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions.

[0036] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the disclosed embodiments of the present utility model can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the gravity direction. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0037] See Figures 1 to 5 , an oil fume extractor, comprising an upper box body 1 and a lower box body 2. The lower box body 2 can move up and down relative to the upper box body 1. The lower box body 2 is at least partially located below the upper box body 1, and the lower box body 2 covers the outer periphery of the corresponding part of the upper box body 1. A fan system (not shown) can be arranged in the upper box body 1 to provide the power for sucking oil fumes. A smoke collecting hood 3 is arranged at the bottom of the lower box body 2. The smoke collecting hood 3 is in the shape of a flat rectangle. Thus, in the rising and shutdown state, the lower box body 2 and the smoke collecting hood 3 can be hidden in the cabinet.

[0038] An air inlet 31 is formed at the bottom of the smoke collecting hood 3. The oil fume extractor further comprises a gesture sensing module 4 arranged at the bottom of the smoke collecting hood 3. The gesture sensing module 4 is preferably located at the front side of the air inlet 31. The bottom surface of the smoke collecting hood 3 at the front side of the air inlet 31 constitutes an installation part 32 of the gesture sensing module installation structure. The installation part 32 is made of sheet metal and is provided with installation holes 33. The installation part 32 is not limited to the bottom surface of the smoke collecting hood of a lifting type range hood, and can also be an appropriate position of other types of range hoods, such as the front side surface of the smoke collecting hood, etc. The installation part 32 (including the installation holes 33) and the gesture sensing module 4 constitute the gesture sensing module installation structure.

[0039] The gesture sensing module 4 comprises a main body 41, a mounting bracket 42 and a base 43. The main body 41 refers to the module including a gesture sensing sensor. The mounting bracket 42 is used to mount the main body 41 on the inner side of the installation part 32. Here, the "inner side of the installation part 32" refers to the side of the installation part 32 that is not exposed, such as the inside of the smoke collecting hood 3 in this embodiment. An infrared window 411 is arranged on one side of the main body 41 facing the mounting bracket 42 for the emission and reception of infrared rays by the sensor in the main body 41. There are two infrared windows 411, which are usually arranged at intervals left and right in the installation state.

[0040] The mounting bracket 42 is provided with an opening 421, and the position of the opening 421 corresponds to that of the infrared window 411. There are also two bases 43, and one base 43 can be arranged at each opening 421. Each base 43 includes a convex platform 431 which protrudes in a direction away from the main body 41. The position of the mounting hole 33 on the mounting part 32 of the above smoke collecting hood 3 corresponds to that of the convex platform 431, and the shape and size of the mounting hole 33 also correspond to those of the convex platform 431 respectively. The convex platform 431 penetrates into or passes through the mounting hole 33 at least partially from the inner side of the mounting part 32, so as to be exposed outside the mounting part 32, flush with the outer surface of the mounting part 32 or partially embedded in the mounting hole 33. In this embodiment, it is preferably flush. The base 43 is at least transparent at the convex platform 431. The size of the convex platform 431 is larger than that of the infrared window 411, and the projection of the infrared window 411 on the outer surface of the convex platform 431 is within the contour range of the outer surface of the convex platform 431. The outer surface of the convex platform 431 refers to the surface away from the main body 41, that is, the surface exposed through the mounting hole 33, and this outer surface is a plane. The inner surface 432 of the base 43 facing the inner side of the mounting part 32 of the smoke collecting hood 3 is a plane, and the surface of the base 43 located on the outer periphery of the convex platform 431 can be fixed to the inner side of the mounting part 32 in the form of glue or the like.

[0041] The mounting bracket 42 can be fixed to the inner side of the mounting part 32 in the form of glue. The inner surface 432 of the base 43 is closer to the main body 41 than the side of the mounting bracket 42 facing the main body 41. The inner surface 432 of the base 43 is in close contact with the main body 41. Considering the sealing performance of the installation fit between the main body 41 and the base 43, an elastic component 412, such as a foam strip, etc., is pasted corresponding to the outer periphery of the infrared window 411. The elastic component 412 protrudes from the infrared window 411, and the size of the base 43 is larger than that of the elastic component 412. The projection of the elastic component 412 on the inner surface of the base 43 is within the contour range of the inner surface of the base 43, so as to ensure the effective fit of the elastic component 412.

[0042] The mounting bracket 42 is also provided with a fixing hole 422, and thus the mounting bracket 42 can be fixed to the main body 41 by a fastener, such as a screw 45, etc., passing through the fixing hole 422.

[0043] Thus, by separating the infrared-transmitting convex platform 431 of the gesture sensing module 4 from the mounting bracket 42 and the main body 41, first installing the base 43 on the mounting part 32, and then fixing the main body 41, the installation gap can be ensured. The mounting hole 33 of the mounting part 32 cooperates with the convex platform 431, reducing the opening area, further ensuring the installation gap, and reducing the damage to the mounting surface of the mounting part 32. Moreover, the way of fixing the base 43 and the mounting part 32 with glue will not damage the surface of the mounting part 32.

[0044] Embodiment Two

[0045] See Figures 6 to 9, in this embodiment, the difference from the above-mentioned first embodiment is that two independent mounting brackets 42 are provided and arranged symmetrically left and right. Instead of providing a separate base 43, a boss 431 is formed on the mounting bracket 42, and the rest of the lower surface of the mounting bracket 42 except the boss 431 is a plane. The mounting brackets 42 are symmetrically bonded and fixed to the inner side of the mounting portion 32.

[0046] The above-mentioned overall parts can be used interchangeably left and right, which improves the generalization rate of materials and reduces the production and manufacturing costs (no anti-fooling treatment is required during production and processing, and only two sets of molds are needed, etc., which reduces the comprehensive cost of materials).

[0047] The gesture sensing module 4 further includes nuts 44. Each mounting bracket 42 is formed with a mounting groove 423, which can be used to fix the nuts 44 so that the nuts 44 are embedded and fixed. A positioning notch 424 is formed on the opposite side of the mounting bracket 42 (corresponding positioning structures can be provided on the inner side of the mounting portion 32 of the smoke collecting hood 3 or on the main body 41 for positioning during installation).

[0048] During installation and fixation, the left and right mounting brackets 42 are respectively fixed to the inner side of the mounting portion 32 of the smoke collecting hood 3 by means of adhesives, etc. Then, the main body 41 is placed on the mounting brackets 42 and reliably fixed by the cooperation of screws 45 and nuts 44.
