Description

Self-Cleaning Filter Hood Assembly The present invention relates to a hood assembly, and more specifically, to a hood assembly that allows for clean use by enabling self-cleaning of the filter. Generally, kitchen hoods are installed above cooking appliances to expel odors and contaminated air produced during cooking. The hood is positioned low above the cooking appliance to quickly and effectively exhaust contaminated air generated from the appliance. The hood is connected to a duct to vent the contaminated air to the outside. Conventional range hoods are equipped with filters along the airflow path to purify contaminated air before exhausting it. However, in conventional hoods, contaminated air accumulates on the filter surface as it flows along the hood. Filters clogged with such accumulated contaminants fail to function properly, and in some cases, there were hygiene issues where the accumulated contaminants fell onto food on cooking utensils. FIG. 1 is a perspective view illustrating the front configuration of a hood assembly of the present invention. FIG. 2 is a perspective view illustrating the rear configuration of the hood assembly of the present invention. FIG. 3 is an exploded perspective view illustrating the assembly process of the hood assembly of the present invention. FIG. 4 is an exploded perspective view illustrating the configuration of the hood assembly of the present invention in disassembly. FIG. 5 is a cross-sectional example illustrating an example of use of the hood assembly of the present invention. FIGS. 6 to 8 are cross-sectional examples illustrating the use process of a hood assembly according to another embodiment of the present invention. Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the invention and the accompanying drawings, under the premise that identical reference numerals in the drawings refer to identical components. When a component is described as "comprising" another component in the detailed description of the invention or the claims, this shall not be interpreted as being limited to being composed solely of said component unless specifically stated otherwise, but shall be understood as potentially including additional components. FIGS. 1 and FIGS. 2 are perspective views showing the configuration of the hood assembly (100) of the present invention from different directions, FIG. 3 is an example diagram showing the assembly process of the hood assembly (100), and FIG. 4 is an exploded perspective view showing the configuration of the hood assembly (100) disassembled. As illustrated in FIGS. 1 to 4, the hood assembly (100) of the present invention comprises a casing (110) positioned between the upper part of a cooking appliance (A) and the ceiling, a filter frame (120) positioned at an angle inside the casing (110), a filter (130) detachably coupled to the filter frame (120), a filter connecting pipe (140) coupled to the back surface of the filter (130) to guide contaminated air (G) discharged from the filter (130), an internal connecting pipe fixing plate (150) that fixes the filter connecting pipe (140) to the casing (110), and a duct connecting plate (160) that connects a duct (200) to the back surface of the casing (110). The casing (110) is provided on the upper part of the cooking appliance (A) as shown in FIG. 5 and supports each component so that contaminated air (G) generated from the cooking appliance (A) is discharged through the interior to the duct (200). The casing (110) is provided in the form of a housing with the top and bottom open. The casing (110) is positioned so that the open bottom faces the cooking appliance (A). The casing (110) includes an opening frame (111), a front wall (112), a rear wall (113), and a pair of side walls (115) joined along the front, rear, left, and right directions of the opening frame (111). The opening frame (111) supports the front wall (112), the rear wall (113), and a pair of side walls (115) so that they remain joined together. The front wall (112) and the rear wall (113) each have an upper frame connecting ledge (113a) formed by bending at the top, so that the upper ends are joined to the opening frame (111). Here, the height of the front wall (112) is lower than the height of the rear wall (113), thereby ensuring sufficient front space for the user to be positioned in front of the cooking appliance (A), as shown in FIG. 5. A pair of side walls (115) are provided in a trapezoidal shape, the upper upper jaw (115a) is connected to the opening frame (111), and the lower lower jaw (115b) is connected to the duct connecting plate (160). The filter frame (120) is coupled at an angle inside the casing (110) to support the filter (130) in a detachable manner. As shown in FIG. 3, the filter frame (120) includes a frame plate (121) that fixes the filter (130), a lower fold support plate (125) that is folded over a certain area at the bottom of the frame plate (121)
