1 TARIFF A sliding hood with a front-mounted bolt lock. TECHNICAL AREA 5 The present invention relates to a sliding range hood with a pull-out screen. This is especially relevant for a lockable sliding range hood. STATE OF THE ART 10 Sliding range hoods (extractors) generally consist of smoke collection systems located within a housing. the area and suction inlet, the fan-motor assembly that feeds it and the outlet duct; oil on the lower side The retaining filters are in the form of a pullable sliding plate that can be extended towards the user at the front. front element; guide rails carrying the retractable front element from opposite sides; 15 It includes lighting and control units. The front element is retractable when the slider is pulled forward. By progressing, the suction area is increased and flow conditions are improved. The rails are linear. By providing guidance, it ensures the retractable front element moves forward without oscillating. It is doing so. The oil suspended in the suction air that is advancing towards two adjacent filter suction ports... It holds the particles. The cables required for a control panel and lighting are on the front panel 20 or it is transported within the interior space by passing through the casing. In sliding systems, the sliding mechanism is closed. Afterwards, keeping it securely closed provides both user convenience and product safety. This is critically important in terms of functionality. However, issues that may arise in existing systems over time... The slide may malfunction due to mechanical clearances, vibrations, or tolerance deviations from manufacturing. The mechanism can open or loosen spontaneously. In traditional solutions, 25 A plastic stopper is usually used to secure the slide, and this stopper is made of metal. is fitted onto the surface. However, plastic and sheet metal have different surface properties (especially surface its roughness (Ra value) and different mechanical strength levels over time This causes the plastic surface to deform and wear down. Such wear and tear... the bolt fails to perform its locking function, giving a loose feeling and at least 30 Ultimately, this can lead to malfunctions. The EP2796796 spring can optionally be fitted with a spring-driven retraction mechanism or a spring-driven mechanism. It describes a range hood with a modular unit for producing an exhaust extraction device. This unit switches the hood's vapor curtain from an open (pushed out) to a closed (pushed in) position. to manufacture a spring-driven retraction device for the purpose of bringing the device into a (retracted) state, or 2 Spring-driven ejection to move the steam curtain from the closed to the open position. It includes an optional spring assembly that can be used to produce its assembly. A BRIEF DESCRIPTION OF THE INVENTION The purpose of the invention is to provide a mechanism for locking the retractable front element and for locating the switch. The requirement is the provision of a sliding range hood. To achieve the aforementioned purposes, the invention consists of a housing with a suction port, a housing... a front panel that can move in a linear direction and a panel holder that supports the front panel 10 a retractable front element having a section; the retractable front element is linear on the housing. Guides are rails that run along a guide bearing arranged in a controlled manner; guides a switch adapted to the front face of the bed; a rear filter located at the suction port This relates to a sliding range hood that includes a filter assembly. The sliding range hood has a pull-out front panel. A stopper is provided on the element and it is fixed in the housing adjacent to the rail, creating a locking mechanism. 15 in a position where it can be locked into a stopper and in a housing where the switch is located It includes a bearing. The bearing engages with the stopper for locking the stopper. It also has a switch on it. In this case, it is a fairly compact sliding hood. The structure can be obtained. Ideally, a guide channel and closure parallel to the rail should be installed between the stopper and the bearing. during which the guide channel engages in a defined direction of progression toward the housing A guide lever is provided. When the retractable front element is closed towards the housing... The guide arm moves along the guide channel, pulling the front element through the first and second guides. If the bed deviates over time due to the weight of the front panel, 25 It corrects the movement, ensuring that the slider moves smoothly. Ideally, a closed end of the guide rod should be placed against the corresponding face in the guide channel. It is in the form of a snap-fit ​​tab that locks into place. In this way, the guide arm only slides through the bolt. It not only corrects its movement but also, for example, the closed 30 of the retractable front element In this position, the retractable front element, by providing a locking mechanism, resists unwanted linear movement. It provides security. In addition to the force applied for the sliding movement with the interlocking mechanism, simply... By applying additional force and pulling the front tension element, the claw is flexed and the connection is established. It is opened. In this way, the retractable front element of the nail is pulled with additional force, guiding it. It is possible to remove it from the surface in the channel. 35 3 Ideally, a side rail adjacent to and parallel to the bed, carrying the guide channel onto which it bends. A wall has been provided. The side wall achieves a compact stopper assembly adjacent to the rail. It ensures that it is done. Ideally, the front wall of the bed should be a frame that is adjustable so that the switch is accessible from the outside. 5 It includes a frame that allows access to the switch from the front wall of the bed and the bed itself. It strengthens it structurally. Preferably, the guide bearing should have a front wall forming a plug that covers the front face of the guide bearing. It is provided at the front end. In this way, by mounting the bed onto the guide bearing, the guide 10 It is possible to close the front of the bed. In addition, the switch can be easily opened from the front wall. It is accessible. Preferably, the guide channel should extend inwards from one front end along one side edge of the front wall. It is shaped in this way. In this way, access from the front wall to the front end of the guide channel is facilitated. Guide 15 Thanks to its accessibility from the side edge of the channel, it can be adapted to the retractable front element. The corresponding arm of a stopper, when pulled, closes only in the direction of the front element. It is easily inserted into the canal with a pushing motion. Ideally, the front end of the guide channel is positioned adjacent to the frame through which the switch is accessed. In this way, 20 The functional parts of the bed where force is applied are held together, making it a compact bed. is obtained. Ideally, the stopper and bearing are manufactured from a single piece of plastic injection molding. This way, both are... It is both easy to manufacture and has a flexible structure with a guide arm and channel. 25 It is possible. Ideally, a tab on the bed can be inserted into a hole in the guide bed wall. It has been passed in this manner. In this way, the bearing is strongly mounted to the guide bearing. Ideally, the switch is a rocker switch. This allows for easy front-mounting of the switch to the bed. This is ensured, and the functional elements of the range hood can be activated with multiple buttons. It is possible to obtain it.

The enclosure (10) is located at the bottom and comes out when open. In the closed position In the filter assembly (50), the pre-filter (52) and rear filter (54) of the same form and size are stacked on top of each other. It is aligned. In the open position, the pre-filter (52) extends outwards, so the total filtering area It doubles with the rear filter (54). Front face (15) of the first guide bearing (12) 5 It is flat and has an adjustment switch (60) on it. A rocket switch (60) controls the fan speed. It activates the step change and lighting element (30) switching functions. Figure 2 shows the retractable front element (20) in perspective before closing from the rear. It has been shown. Here, the term referred to as closing means that the retractable front element (20) is attached to the housing 10 (10) The filter assembly (50) consists of joining the front and rear filters (52, 54) on top of each other. The pullable front element (20) is made of a single sheet metal. Sheet metal punching and forming process It was obtained with. The front edge of the retractable front element (20) is in a J-like form along its entire length. The panel holder part (22) is formed by bending. The panel holder part (22) extends outwards. It has a planar form. A front panel (70) is attached to the retaining part with the help of connecting elements 15 (22) can be fixed to the front face (72). The pullable front element (20) on the housing (10) The rail (23) moves through the correct guide bearings (14, 16) without any jamming. It operates as a sliding, safe linear guide. The rail (23) has outwardly curved ends. It has a U-shaped cross-section. The front end of the rail (23) is mounted on a stopper (40). Stopper (40) It is made of one-piece plastic injection molding. The stopper (40) is inward from its circumferential edges (here inward 20 The expression is defined as a bracket structure extending to the housing (10). The stopper (40) The body (41) rests on the inner surface of the panel holder part (22) via a flange (48). Panel The retaining part (22) has holes (25) that access the front panel (70). Located on the flange (48) A hole is made in the area, axially aligned with the hole in the retaining part (22). A screw is inserted here. (not shown) is attached. In this way, the flange (48) is connected to the retaining part (22). 25 The circumferential edges of the rail (23) on the inward-facing part of the body (41) adjacent to the flange (48). There is a rail groove in the form of a channel where the track will sit. Adjacent to the rail groove and a guide arm (42) extending inwards on the side wall, flexible with a claw at its end It is an extended plastic strip. The guide arm (42) is adjacent to and parallel to the rail (23) of the body (41) It extends inwards on the lateral edge at the periphery. The guide arm (42) extends 30 from the lateral wall to the body. (41) A shoulder form is created on both sides of the part where it is attached. On the body (41) An assembly opening is located in the area enclosed by the lateral edges at the periphery. The assembly opening... It opens onto a wedge which is wrapped around the back of the front panel (70) (74) and is secured with a screw. It is fixed to the wedge. In this way, the stopper (40) is attached to both the body (41) and the flange (48) It is fixed to the front panel (70) at both ends. The front face of the front panel (70) (72) is flat. 35 and a glass panel (not shown) is mounted here. The bed (80) is a hollow prismatic It is in the form of a stopper and is made of plastic material. 6 Stopper (40) from the rear (74) to the front panel (70) and the panel holder part (22) that carries it transversely. It is fixed by extending. On the one hand, the rail (23) is passed through a rail housing from its front free end. It is mounted. The pullable front element (20) is mounted to the housing via the guide bearings (14, 16). (10) If mounted like a drawer with rail (23), the bed (80) is fixed inside the housing (10) 5 It remains and faces the back (74) from one of its front walls (86). The bed (80) is a single piece. It is a plastic cage-like piece. The front wall (86) is flat and level and parallel to the back face (74). The side wall (84) extends perpendicularly inward from the lateral edge of the front wall (86). A guide The canal (82) curves inwards parallel to the top of the lateral wall (84) from the edge. Both The side wall (84) and the guide channel (82) are parallel and adjacent to the rail (23). 10 The distance of the guide channel (82) from the rail (23) on the housing (10) is the guide arm (43) It is adjusted to take on progress. The guide channel (82) is a short-sided U-shaped It has the form and the width narrows while the depth of the inward guide channel (82) is constant. The inward end of the guide channel (82) lies straight. Thus, the guide channel (82) is in the form of a right trapezoid with its wide edge facing the retractable front element (20). 15 As the retractable front element (20) moves to the closing position, the guide arm (42) moves forward. It accesses the entrance part of the guide channel (82) which is aligned with its axis with its claw. Entrance Because the part is wide, the guide arm (42) from the end where the nail is located into the guide channel (82) It reaches. The guide arm (42) pushes inward 20 by applying contact and pressure to the guide channel (82). It slides. Passing through the guide channel (82), the arrow-shaped guide channel (82) at the bottom. It fits into the inner edge and provides locking. When locked, the bed (80) is flat. The flat front wall (86) is fitted with the front panel (70) from the rear (74) and in the closing direction. It stops the progress. During closing, the guide arm (42) in the narrowing guide channel (82) as it moves forward, it is pushed towards the axis of advancement in the middle of the guide channel (82), 25 The guide arm (42) is guided by correcting its axial position in the direction of advancement. It flexes horizontally only in the direction of the body (41) and, by its form, resists vertical flexing. It resists. Therefore, as the guide arm (42) moves through the guide channel (82), the guide The guide arm (42), stopper (40) narrows by forcing the channel (82) to flex vertically. The rail (23) on which the body (41) is rigidly fixed and the vertical positions of the front panel (70) 30 The guide channel (82) corrects on the central axis. The guide arm (42) is in strip form. because and its wide face lies on the stopper (40) parallel to the rail (23) lateral It has a flexible structure but resists stretching in the vertical direction. This allows for a retractable front panel. When element (20) is pulled out by vibration or other forces, the claw resists this 35 shows and blocks the outward movement of the retractable front element (20) on the rail (23). However, when pulled out with additional force by a user, the nail guide 7 By freeing itself from the straight edge of the channel (82) and the guide arm (42) flexing sideways, the guide It allows it to be taken out through the canal (82). Figure 3 shows the position of the switch (60) mounted on the bed (80) and the guide bearing (14). It is shown in close-up. Switch (60) is aligned in the middle of the front face (15). Switch (60) 5 It has two buttons located next to each other and in parallel. One of them controls the fan speed. While adjusting, the other activates the lighting element (30). rocker switch Alternatively, a short-course multi-button switch can also be used. The bed (80), guide bed (14) has holes (141, 142) in the upper wall and side wall. It has flexibly removable claws (811, 812). One of the claws (141) The other nail (812) is located in the middle of the flat upper wall (81) and at the bottom of the lateral wall (84). In this way, when the plug-like bed (80) is placed so that it covers the front face (15), the side The wall (84) and the adjacent upper wall (81) are fixed to the guide bearing (14). The upper edge of the inner side of the guide bed (14) is vertically flat and straight, like the housing (10) 15 It is adjacent to the lateral wall (11). In this way, the guide bearing (14) is simply attached to the side of the housing (10). It can be fixed to the wall (11) with weld seams under the guide bed (14) on the front face. (15) bed (80), with the front wall (86) placed on the front edges of the guide bed (14). It is fixed. In this case, the transverse extension from the inward-facing side edge of the front wall (86) The guide arm (42) of the stopper (40) fits into the guide channel (82) vertically as if it were placed in a slot 20 It is accessed by advancing. To facilitate access, an indentation (861) is made on the side edge of the front. It was applied to the wall (86). The guide channel (82) was obtained by bending it inwards through the recess (861). It has been done. Figures 4a and 4b show the bed (80) from the outside and inside, respectively. A single-piece cage 25 The plastic bed (80) in its structure has a space on its front wall (86) allocated to each button. A frame (83) is located.
