It is related to the range hood. STATE OF THE ART 10 A range hood filters and ventilates cooking vapors and fumes in kitchens. It is used to discharge the contents into the system, the outside environment, or back into a closed area. A range hood contains a type of device that moves air; this is usually a fan or blower. Preferably a fan or blower, to expel the air from the enclosed space to the desired level or 15 The hood is selected to be large enough to provide the desired airflow rate for processing. In this case, the fan is usually housed inside the casing. This applies to ductless fans used in kitchens. The range hood filters the dirty air drawn from the environment and discharges it back into the room. It is ductless. In this type of range hood, called a "hood", the dirty air is drawn in by a fan and then processed through a metal... and is passed through a carbon filter and blown into a channel through an exhaust opening 20 From here, it is discharged back into the environment through the exhaust opening. EP2610556 relates to a filter configured for use in a range hood, and each of them It contains numerous housings adapted to accommodate its own filter element. These numerous The housings are positioned side-by-side, defining a filtering surface and placing 25 to be filtered into the filter. It has an air inlet to introduce air. This is why many enclosures have an air inlet. at least part of its circumference is placed around the filter, thus creating a side filtration surface. It consists of a pair of housings, each adapted to hold the respective filter element in place. It includes a longitudinal guide and an opening for placing this filter element into the double guide; The opening is located at the opposite end of the guide rails to the air intake. 30 A BRIEF DESCRIPTION OF THE INVENTION The invention is a lightweight range hood that directs the suction air outwards through its lateral outlets. is to ensure. 35 2 To achieve the aforementioned purpose, the invention involves, on the one hand, a suction device via a suction head. it draws in air and on the other hand, it is drawn in through an exhaust opening provided in its housing. an intake casing that blows air; an exhaust opening at the bottom of which is a chimney flue It refers to a range hood that includes a chimney that rises in a confining, coiled manner.

By forming an edge, it is fixed in the chimney duct at the top and draws air from the front edge. a single piece of sheet metal bent in such a way as to direct the current to the corresponding lateral outlets It includes a deflector plate. The deflector plate divides the suction airflow into lateral outlets. distributing and during the discharge of the suction air to the outside environment, due to air flow, 10 It reduces noise. Ideally, the deflector plate should be adjusted so that each one faces the corresponding lateral outlet, and It includes a first panel and a second panel, both of which form a flat edge where adjacent edges form the leading edge. Two integrated panels create resistance to airflow, dividing the front edge from the airflow by 15 It divides the chimney flue and, thanks to the slope, gradually narrows it, increasing the air velocity at a constant acceleration. increasing and creating noise inside the chimney as the suction airflow reaches the discharge point. It prevents. Ideally, the top edges of the first and second panels should be 20 inches from the top edge of the corresponding lateral exit. The adjacent setting is adjusted. In this way, the air velocity when the suction airflow reaches the lateral outlet is adjusted. This is maximized. Thus, the intake air is drawn in without creating turbulence at the lateral outlet. It can be evacuated. Ideally, the deflector plate should be a V-shaped 25-inch panel, with each extension forming the first and second panels. It is in this form. Thus, the suction airflow is equally divided in two directions through the middle of the pipe channel. accelerated in this way and without causing high noise in the corresponding lateral exits. It can be evacuated. Ideally, the leading edge is positioned perpendicular to the exhaust opening's intake airflow direction. This 30 In this way, the suction air stream is divided into lateral outlets without creating turbulence and vibration. Guidance is provided. Ideally, the deflector plate is positioned to close the flue duct transversely from above. This In this case, the deflector plate processes the entire suction airflow alone, 35 It can be guided and no additional parts are needed. 3 Ideally, a tray that secures the deflector plate at its edges and covers the top of the chimney. This is ensured. The tray is mounted by remaining suspended in the flue duct of the deflector plate. It allows air to escape while also preventing air from passing through the top of the chimney. Preferably, a column that is fixed to the housing at one end and extends to the tray at the other end. A carrier platform is provided. The carrier platform bridges the gap between the housing and the tray. It performs this function by ensuring the structural integrity of the range hood. Ideally, the tray should extend downwards from its outer edge, with one end of the column and the deflector attached to it. It includes a skirt section to which the plate is attached at the collar. The skirt section is both 10 by assembling both the deflector plate and the column and mounting them onto the tray. It provides. Preferably, the column is an L-shaped section adjusted so that its outer surface rests against the inner corner of the skirt. It is a profile in the form of a bracket. In this way, the column is mounted both as an angle bracket and as a shape connection 15 It creates a flow from end to end without disturbing the airflow in the chimney flue from the inside. It lies along the canal. Preferably, the collar is adjusted so that it sits on the inside of the hem, and the collar... It is provided at the edge and contains a recess through which the upper end of the column passes. The recess is 20 Thanks to this, the column is attached to the corner of the skirt section, and the deflector is attached to the inner edges. The plate is securely held in place. There is no need for a separate mounting part. Preferably, the carrier platform is positioned diagonally within the enclosure to allow exhaust air intake to be blown out. It contains at least one pair of columns extending parallel to the direction. Thus, it serves as both a load-bearing structure. the platform will prevent vibration during hood operation its strength is increased and it extends while occupying the least amount of space in the chimney flue. is provided. Ideally, the skirt section is fitted airtight to the top of the chimney. This ensures the chimney is 30... Without a separate outlet from the duct, the suction air is directed to a lateral outlet by the deflector plate. It is being redirected. Ideally, the front edge should be installed transversely through the chimney, dividing the flue pipe into two sections. It extends. In this case, the suction airflow is evenly distributed to different lateral outlets at the same 35°. By controlling the flow rate, quiet operation is ensured. 4 Ideally, the chimney flue should be inserted so that the leading edge is below the lower edge of the lateral outlets. It extends. In this case, the airflow begins to accelerate before the lateral exit. and air output efficiency is increased.

The vapor flows to the filter (not shown) located at the bottom of the vapor suction nozzle (1). To ensure fluid transmission, the suction head (1) has a suction head with a fan on top. It is mounted on the body (50). The suction body (50) has a cube-like housing (52). 35 A fan (6) that provides suction by means of a snail is mounted inside the housing (52). The suction body (50) creates negative pressure on the suction head (1) to draw in ambient air. It enables the suction. A control panel is placed on the suction head (1) and the suction body (50) It is connected in such a way as to provide signal transmission to the suction body (50) via the control panel. The fan's operating speed can be selected. The suction air is located in the upper part (53) of the housing (52). The air is blown upwards by means of an exhaust opening (54). The exhaust opening (54) is a The chimney (10) surrounds the lower part (18). The chimney (10) has an extended body and is above 5 It is a rising rectangular prism structure. The chimney (10) is made by bringing together the panels. It was formed and a chimney channel was confined within it. At the top of the chimney (10) (12) There are lateral exits (14) on opposite walls. The lateral exits (14) are at the top. (12) are patterned grid-shaped holes that run the length of the panel. The chimney (10) a square-shaped, leakproof tray of suitable size for the top surface that it leaves open (40) 10 It is placed. The top plate (42) of the tray (40) is made of flat and smooth metal and the chimney is in the center of it. A hole (44) was opened that accessed the canal. Figure 2 shows the hood from the front perspective with some of the outer panels of the chimney (10) removed. It is shown as follows. A column in the form of an L profile is placed at each corner of the cube-like casing (52). (22) are mounted from the lower ends. Thus, a support platform formed by the columns (22) 15 (20) supports the housing (52) and the suction head (1) to which it is attached from its lower end. The columns (22) are straight in form and are located at the corners of the rectangular cross-section chimney flue. The outer panels of the chimney (10) are attached to the carriers with the help of suitable holes on the outer surface of the columns (22). It is mounted on the platform (20). The central exhaust (53) on the top of the housing (52) The opening (54) is circular in form and the flue channel is concentric. Columns (22) on top 20 It is mounted on the tray (40) from the end (23). As shown in Figure 3, the tray (40) rectangular flat top plate (42) with its outer periphery extended inwards, skirt part (46) It has been formed. Connection holes (47) have been made in the corner sections of the skirt part (46). Upper A hole (44) is made in the center of the plate (43). The deflector is on the outside of the hole (44). It is looking at the plate (30). As shown in Figure 4, the deflector plate (30) is one-piece and 25 It is obtained by cutting the metal sheet and then bending it into a V-shape. Thus, a deflector is formed. The plate (30) consists of a first panel (32) and a second panel (34) that are angled and joined together. It consists of two extensions. The angle of inflection between the first and second panels (32, 34) is an attack. The angle (a) is formed and selected as 90 degrees. The bending section with the angle of attack It forms the front edge (36) along its entire length. Apart from this, the first and second panels (32, 30 34) the outward-facing edges are folded upwards and parallel to each other to form a collar (33, 35) was obtained. Each collar (33, 35) had a groove (37) created by cutting the outer edges. It has. In addition, holes corresponding to the connecting holes (47) are made in the collars (33, 35). As shown in Figure 3, the collars (33, 35) correspond to the inner edge of the hem (46). They are positioned along the edges. In this way, the attachment holes on the collars (33, 35) are positioned on the skirt 35 It is aligned with some connection holes (47) in this part and a connecting element, for example 6 The tray (40) and the deflector plate (30) are connected to each other by riveting or screwing. Holes have also been drilled in the top plate (42) of the tray (40) for the purpose of mounting a range hood. As shown in Figure 2, the columns (22) are on the outside of the top (23) and on the inside of the skirt (46). It is placed on the tray (40) so that it faces the top of the columns (22). In this case, the top of the columns (22) Some holes in the part correspond to the connection holes (47) in the skirt part, connecting the tray (40) with 5 The carrier platform (20) is assembled with a detachable connection. The skirt of the tray (40) from the inner surface of part (46) to the outer surfaces of the collars (33, 35) of the deflector plate (30). because it sits on the column (22) tray (40) thanks to the recesses (37) in the corners It can be placed. After the assembly of the column (22) from the top end (23) to the tray (40) is completed Then the outer panels are fixed to the outside of the columns (22) to form the chimney (10). This 10 In this case, the lateral outlets (14) at the top (12) of the chimney (10) and the deflector plate (30) The boundaries of the false outlets (14) are aligned with the flue channel of the deflector plate (30). It is adjusted according to the distance inside. That is, the front edge (36) of the deflector plate (30) It lies in the chimney channel, below the lower edge of the lateral outlet (14). In addition, the far edges of the first and second panels (32, 34) are at the corner line of the skirt part (46) and 15 It is adjusted adjacent to the lateral outlet (14) from the upper edge. Thus, the deflector plate (30) is positioned in the chimney. It linearly narrows the cross-sectional area of ​​the upper part (12) of the channel up to the lateral exit (14). When the ambient air becomes polluted, the user activates the range hood via the control panel. [Extraction] The fan inside the housing (50) works by drawing the dirty air of the environment through the suction nozzle (1). It passes through the filter. The filtered air coming from the suction nozzle passes through the top 20 of the housing (52). It is discharged from the exhaust opening (53) in part (54) towards the chimney channel. Chimney (10) from the flue channel bounded between the inner surface of the panels and the inner part of the columns (22) The rising suction air ascends along the rectangular, fixed cross-section. Thus, the deflector... The intake airflow is divided by the angle of attack (a) of 45 degrees from the front edge (30) of the plate (36). The attack splits into two at an angle and is directed towards the lateral exits on the opposite sides. During this time, the attack 25 Due to the angle of 90 degrees, the first plate (32) and the second plate (34) are directed towards the lateral exit. (14) By narrowing the correct chimney cross-section, it accelerates the intake air and from the lateral outlet (14) outwards. It is receiving.
