Description

Technical Field

[0001] The utility model relates to the field of oil nets used in range hoods, in particular to an oil net for a range hood. Background Art

[0002] Currently, range hoods are equipped with an oil screen at the air intake to prevent larger debris (such as plastic bags) from entering the interior of the range hood. In addition, the oil smoke airflow can only enter the range hood through the oil screen. When the oil smoke airflow contacts the surface of the oil screen structure, a portion of the oil in the smoke will adhere to the oil screen, which can relatively reduce the amount of oil stains adhering to the inner wall and fan blades of the range hood. When the surface of the oil screen structure is adhered to oil stains, the friction effect of the oil screen structure on the airflow is enhanced, and at the same time, the ability to relatively adhere to the oil in the oil smoke airflow is also enhanced. In order to enhance the ability to relatively adhere to oil, some oil screens in the prior art adopt a fine mesh structure, such as the "oil guide groove of a double oil screen" with Chinese utility model patent publication number CN203286624U. Although this type of oil screen has a better effect on relatively adhering to oil, that is, a better oil filtering effect, it also has a large wind resistance. In addition, the fine mesh structure is accompanied by the problem of difficulty in cleaning, and replacing the oil screen also leads to increased cost of use. In order to facilitate cleaning, some oil screens in the prior art adopt a simple open groove structure or a punched and flanged groove structure, such as the "an oil screen assembly" with Chinese utility model patent publication number CN213480315U. This type of oil screen is in contact with the oil smoke airflow for too short a time and has too small a contact area, resulting in a poor effect on relatively adhering to oil. Therefore, it is necessary to make an oil screen that is easy to clean and has a good oil filtering effect. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide an oil screen for a range hood, which is easy to clean and has a better oil filtering effect.

[0004] The purpose of this utility model is achieved through the following technical solutions.

[0005] The oil net of the range hood disclosed by the utility model comprises a groove assembly and a frame, the groove assembly is formed with a groove bottom plate and a groove side plate, the left and right ends of the groove bottom plate are respectively connected to the lower ends of the corresponding groove side plates, and the front and rear ends of the groove bottom plate are respectively formed with a convex sliding plate portion, the frame comprises two rails and two frame bars, the groove side plates are adapted to be arranged between the front and rear two rails, the inner sides of the rails are formed with a transverse slide groove extending along the left and right directions, the convex sliding plate portion is arranged in the corresponding transverse slide groove, the groove assembly is arranged in the left and right directions, the groove assembly is all arranged between the left and right frame bars, the frame bar is detachably installed and connected to the rail, and an air inlet duct is formed between adjacent groove side plates, and the air inlet duct is gradually narrowed from bottom to top.

[0006] Preferably, the front and rear ends of the groove side plates are respectively bent outward to form baffles, and the baffles are abutted and connected to the corresponding rails in the front-to-back direction, and adjacent baffles are abutted and connected to each other in the left-to-right direction.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] The oil net of the range hood of the utility model is as follows Figures 1 to 6 As shown, it includes a slot assembly 1 and a frame 2. Figure 7 and Figure 8 As shown, the slot assembly 1 is formed with a slot bottom plate 11 and a slot side plate 12. The left and right ends of the slot bottom plate 11 are respectively connected to the lower ends of the corresponding slot side plates 12. In other words, each slot assembly 1 includes two slot side plates 12. The slot bottom plate 11 and the slot side plates 12 can be integrally connected. The front and rear ends of the slot bottom plate 11 are respectively formed with a convex slide plate portion 111. The convex slide plate portion 111 and the slot bottom plate 11 can be an integrated structure. In other words, the convex slide plate portion 111 is the portion of the slot bottom plate 11 that protrudes outward. Figure 2 As shown, the frame 2 includes two rails 21 and two frame bars 22, and the groove side plate 12 is adapted to be arranged between the front and rear rails 21, so that the rails 21 position the groove assembly 1 in the front and rear directions to prevent the groove assembly 1 from loosening in the front and rear directions; Figure 7 and Figure 8 As shown, a transverse chute 211 extending in the left-right direction is formed on the inner side of the rail 21, that is, the transverse chute 211 passes through the rail 21 in the left-right direction. Specifically, a corresponding transverse chute 211 is formed behind the rail 21 located at the front position, and a corresponding transverse chute 211 is formed in front of the rail 21 located at the rear position. The convex slide portion 111 is arranged in the corresponding transverse chute 211. In the vertical direction, the width of the transverse chute 211 is adapted to the thickness of the convex slide portion 111. Figure 1 、 Figure 2 and Figure 5 As shown, the slot components 1 are arranged in the left-right direction, and are all located between the left and right frame bars 22. Thus, the arranged slot components 1 are all located within the range of the frame 2 (when viewed from above). The frame bars 22 are detachably connected to the rail bars 21. Specifically, the two rail bars 21 are parallel to each other, and the two frame bars 22 are parallel to each other. The left and right ends of the rail bar 21 located at the front are respectively connected to the front end of the corresponding frame bar 22, and the left and right ends of the rail bar 21 located at the rear are respectively connected to the rear end of the corresponding frame bar 22, thus making the frame 2 rectangular. Figure 1 、 Figure 2 and Figure 6 As shown, an air inlet duct 100 is formed between adjacent trough side plates 12, and the air inlet duct 100 is gradually narrowed from bottom to top. In other words, as shown in FIG. Figure 8 As shown, the two groove side plates 12 on the same groove assembly 1 are gradually arranged from top to bottom, so that the groove width of the groove assembly 1 (in the left-right direction) is greater than the groove bottom width of the groove assembly 1 (in the left-right direction), as shown in FIG. Figure 6As shown, the width of the air inlet duct 100 (i.e. Figure 6 The dimension "W" in the figure decreases from bottom to top. Figure 2 and Figure 6 As shown, a hanging pin 221 is provided on the outer side of the frame strip 22, and the hanging pin 221 can be inserted into the edge of the air intake of the range hood. For example, the hanging pin 221 located on the right is relatively fixed to the corresponding frame strip 22, and the hanging pin 221 located on the left is connected to a compression spring, so that the hanging pin 221 located on the left can be extended and retracted in the left and right directions. Therefore, the hanging pin 221 located on the right is first inserted into the right edge of the air intake of the range hood, and then the hanging pin 221 located on the left is retracted, and then the left end of the oil net is swung up, and then the hanging pin 221 located on the left is released so that the hanging pin 221 pops out and is inserted into the left edge of the air intake of the range hood.

[0022] When the oil screen of the present invention is in use, the oil fume airflow enters the air inlet duct 100 from bottom to top, that is, the oil fume airflow enters the air inlet duct 100 between two adjacent groove bottom plates 11, and then the oil fume airflow passes through the upper end of the air inlet duct 100 and enters the interior of the range hood. Since the air inlet duct 100 is gradually narrowed from bottom to top, the oil fume airflow will be slightly squeezed by the air inlet duct 100, so that the oil fume airflow has good contact with the inner wall of the air inlet duct 100, so that the oil in the oil fume airflow can better adhere to the inner wall of the air inlet duct 100. When the oil screen of the present invention needs to be cleaned, the oil screen is removed from the range hood. For example, the frame bar 22 located on the right side is removed. Since the cross-slide 211 passes through the rail 21 in the left-right direction, the groove assembly 1 moves to the right, and the convex slide plate 111 slides in the slide 211. Then, the groove assembly 1 passes the right end of the rail 21 and slides off the rail 21. Thus, the oil screen of the present invention is disassembled, so that the air inlet duct 100 is disassembled. Figure 8 As shown, the inner wall of the original air inlet duct 100 is transformed into an exposed state, so you can use a scouring pad (for washing dishes) combined with detergent to vigorously clean the inner wall of the air inlet duct 100 (i.e., the outer wall of the groove side plate 12). Because the groove width of the groove assembly 1 is greater than the groove bottom width of the groove assembly 1, the inner wall of the groove assembly 1 is easier to clean. Since the inner wall of the groove assembly 1 is not used for airflow, and the user cannot see the inner wall of the groove assembly 1 when it is installed and used, the outer wall of the groove assembly 1 is the main cleaning object; when cleaning is completed, as shown in FIG. Figure 7As shown, the groove assembly 1 is slid to the left into the frame 2, that is, the convex sliding plate portion 111 is slid from the right end of the rail 21 into the slide groove 211. When all the groove assembly pieces 1 are installed, the frame bar 22 located on the right is installed. Specifically, the end of the rail 21 can be formed with a threaded hole 212. A screw is passed through the frame bar 22 and screwed into the threaded hole 212 to firmly install and connect the rail 21 and the frame bar 22. As can be seen from the above, the oil screen of the utility model is easy to assemble and disassemble, which is beneficial to making the narrow and long (in Figure 6 The inner wall of the air inlet duct 100 (under visual observation) is easy to clean. In other words, the height of the air inlet duct 100 can be increased, thereby increasing the contact time between the airflow and the inner wall of the air inlet duct 100 and enhancing the oil adhesion to the oil screen. In other words, if the air inlet duct 100 is a non-detachable structure, the narrow and long air inlet duct 100 makes it difficult for cleaning tools to enter the air inlet duct 100. As can be seen from the above, the oil screen of the present invention is easy to clean and has a good oil filtering effect.

[0023] Further, if Figure 8 As shown, the front and rear ends of the groove side plate 12 are bent outward to form a baffle 13, and the baffle 13 is perpendicular to the groove side plate 12. Figure 2 、 Figure 3 and Figure 7 As shown, the baffle 13 is connected to the corresponding rail 21 in the front-to-back direction, so the rail 21 has a positioning effect on the baffle 13. During the installation and removal of the slot assembly 1, the baffle 13 slides against the corresponding rail 21, and the rail 21 also plays a guiding role on the baffle 13. Figure 3 As shown, adjacent baffles 13 are connected to each other in the left-right direction, thus making the structure of the air inlet duct 100 stable. During the oil screen assembly process, when the baffles 13 of the slot assembly 1 installed in the frame 2 at the end are attached to the baffles 13 of the slot assembly 1 installed in the frame 2 at the front, the size of the air inlet duct 100 is stabilized. Figure 3 As shown, the sides of adjacent baffles 13 that abut against each other are vertical sides. Figure 3 As shown, the baffle 13 can also prevent the oil smoke flow from overflowing from the front and rear ends of the air inlet duct 100 to the outside of the air inlet duct 100.

[0024] Furthermore, if Figure 3 and Figure 7 As shown, the frame strips 22 are connected to the corresponding baffles 13 in the left and right directions, so that the arranged slot assembly 1 will be blocked by the frame strips 22 located on the left when it moves to the left, and will be blocked by the frame strips 22 located on the right when it moves to the right, thereby preventing the slot assembly 1 from loosening left and right.

[0025] Furthermore, if Figure 8As shown, an inner folding edge 121 is formed at the upper end of the trough side panel 12. In other words, for the trough assembly 1, the inner folding edge 121 is bent inward, while for the air inlet duct 100, the inner folding edge 121 is bent outward. Therefore, the inner folding edge 121 will not have a significant impact on the oil fume airflow, but the inner folding edge 121 can increase the structural rigidity of the upper end of the air inlet duct 100, and prevent the upper end of the trough side panel 12 from being easily bent and deformed.

[0026] Furthermore, if Figure 8 As shown, the trough side plate 12 is a straight plate, which prevents the outer wall of the trough side plate 12 from forming a tortuous or concave-convex structure, so that the outer wall of the trough side plate 12 can be easily wiped clean.
