Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, and in particular to an electronic induction structure of a filter material for a range hood. Background Art

[0002] Currently, most range hoods on the market are designed to discharge the fumes generated by cooking in the kitchen directly to the outdoors through the range hoods. However, various gases and particulate matter still exist in the fumes after simple filtration by the range hoods, polluting the atmospheric environment. Later, range hoods with filter layers appeared, which further purify the fumes in the fume duct through the filter layer, thereby achieving the purpose of protecting the environment.

[0003] Although the filter layer can play a good purification effect, after a period of use, the oil smoke adheres to the filter layer, which will cause the purification effect to decrease. Therefore, the filter layer needs to be replaced regularly to ensure the purification capacity of the range hood. The filter layer is usually large and difficult to replace, which leads to poor user experience. In addition, if the filter layer is not installed in the designated position, the oil smoke will bypass the filter layer through the gap, resulting in a decrease in the purification effect.

[0004] Therefore, there is an urgent need for an electronic sensing structure for range hood filter material that is easy to install and can ensure that the filter element is properly installed. Utility Model Content

[0012] A further technical solution of this embodiment is that the first sensing part and the second sensing part are configured as electromagnetic coils; or the first sensing part is configured as a radio frequency reader, and the second sensing part is configured as a radio frequency tag.

[0013] A further technical solution of this embodiment is that a sealing strip is provided on the top of the inner wall of the installation groove, and the sealing strip abuts against the filter element.

[0014] A further technical solution of this embodiment is that the filter element is in the shape of a flat plate, and is one or more of an activated carbon cotton filter, an activated carbon filter and a glass fiber filter.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are 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 position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] See also Figures 1 to 4The utility model discloses an electronic sensing structure of a range hood filter material, which is applied to a shell 1, a fume channel is formed in the shell 1, at least one mounting groove 2 is provided in the fume channel, a positioning component 4 is provided in the mounting groove 2, a filter element 3 is slidably arranged in the mounting groove 2 through a sliding component, and the positioning component 4 is arranged on one side of the filter element 3 to detect the position of the filter element 3.

[0028] It is understandable that when the filter 3 is installed in the oil fume passage through the installation slot 2, although it can ensure that the largest cross section of the filter 3 is perpendicular to the oil fume passage to ensure the oil fume effect, improper installation will cause the filter 3 to form a gap with the inner wall of the oil fume passage, thereby causing the oil fume to bypass the filter 3, and the oil fume purification effect is poor. In this embodiment, the position of the filter 3 in the installation slot 2 is electronically positioned by setting a positioning component 4, ensuring that the filter 3 is in a suitable position, and the controller connected to the positioning component 4 can start working, avoiding the oil fume pollution problem caused by improper installation of the filter 3.

[0029] Specifically, if Figure 2 As shown, in this embodiment, the positioning assembly 4 includes a plurality of first sensing parts 41 and corresponding second sensing parts 42. The first sensing parts 41 are arranged at the top of the installation slot 2, and the second sensing parts 42 are correspondingly arranged on the filter element 3. The first sensing parts 41 and the second sensing parts 42 are arranged adjacent to each other. When the filter element 3 reaches the accurate position in the installation slot 2, the distance between the first sensing parts 41 and the second sensing parts 42 in the installation slot 2 becomes shorter, and electromagnetic induction occurs to generate micro-current, so that the controller determines whether the filter element 3 is installed in place. On the contrary, when the first sensing parts 41 and the second sensing parts 42 are not adjacent to each other, it is determined that the filter element 3 is not installed in place.

[0030] In this embodiment, the first sensing part 41 and the second sensing part 42 are configured as electromagnetic coils; when the electromagnetic coils are close, microcurrents are generated, thereby sending instructions to the controller. In another embodiment, the first sensing part 41 is configured as a radio frequency reader, and the second sensing part 42 is configured as a radio frequency tag.

[0031] Preferably, in this embodiment, the second sensing parts 42 are arranged at the four corners of the filter element 3 , so as to improve the accuracy of the positioning detection of the filter element 3 .

[0032] like Figure 1As shown, one or more mounting grooves 2 can be fixedly arranged in the oil fume channel to increase the number of filtering layers of the oil fume. A sealing door is arranged on the side of the housing 1 relative to the oil fume channel. The filter 3 in the oil fume channel can be directly replaced by opening the sealing door. The filter 3 is detachably mounted on the mounting groove 2 to facilitate replacement by the user. Specifically, in this embodiment, the filter 3 is fixed to the mounting groove 2 by a jacking screw 5 arranged at the bottom of the mounting groove 2. The filter 3 in the mounting groove 2 is lifted by adjusting the jacking screw 5 so that the filter 3 is pressed and fixed in the mounting groove 2. At the same time, since the oil fume in the oil fume channel rises from the bottom to the top, the filter 3 is lifted to completely cover the top opening of the mounting groove 2 to prevent the oil fume from bypassing the filter 3 through the gap. It should be known to those skilled in the art that the technical solution of detachably installing the filter 3 in the mounting groove 2 by means of interference fit, adhesive setting, etc. should also be within the protection scope of this application.

[0033] The mounting groove 2 in this embodiment includes at least two first groove bodies 21 arranged in parallel. The first groove bodies 21 are provided with U-shaped transverse grooves 22 , and the opening directions of the transverse grooves 22 are arranged opposite to each other.

[0034] Furthermore, the height of the opening is greater than the thickness of the filter element 3, so that the filter element 3 can be placed in the installation groove 2 more smoothly.

[0035] Furthermore, a sealing strip 6 is provided at the top of the inner wall of the mounting groove 2, and the sealing strip 6 abuts against the filter element 3. By providing the sealing strip 6, the airtightness between the filter element 3 and the inner wall of the oil fume passage is further improved, ensuring that the oil fume passes through the filter element 3 during the rising process, thereby improving the purification effect.

[0036] Furthermore, the filter element 3 is in the form of a flat plate, and includes one or more of an activated carbon cotton filter, an activated carbon filter, and a glass fiber filter. The activated carbon cotton of the activated carbon cotton filter has a rich pore structure inside, which can absorb volatile organic compounds in oil smoke, and the activated carbon cotton filter can also absorb water molecules in oil smoke. The activated carbon filter further absorbs volatile organic compounds in oil smoke, and absorbs smoke and smoke odor. The glass fiber filter can intercept tiny particles and harmful substances, and improve the quality of exhaust air, so that the filter structure can effectively remove volatile organic compounds in oil smoke and purify the air, so that the oil smoke can meet the direct emission standard, and the decomposed oil smoke can be directly discharged indoors, avoiding being discharged outdoors and affecting environmental health.

[0037] Furthermore, the screen is also included, the controller is electrically connected to the positioning assembly 4, and the screen is electrically connected to the controller. By setting the screen to intuitively display the installation result of the filter element 3, the user's experience is improved.

[0038] The utility model ensures that the user can accurately install the filter element at the corresponding position in the oil fume passage by arranging an installation groove in the oil fume passage, and by arranging a positioning component in the installation groove, the positioning component further guides the user to install the filter element at the specified position in the oil fume passage, thereby ensuring that the filter element completely covers the oil fume passage and ensuring the filtering and purification effect of the range hood.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
