Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood. Background Art

[0002] Range hoods have become an indispensable kitchen appliance in modern homes. They typically come in two types: top-mounted and side-mounted. Side-mounted range hoods utilize the principle of vortex wind pressure to absorb most of the fumes closer to the stovetop in an arc, minimizing adverse health effects. Furthermore, since the power source is closer to the stovetop, the extraction efficiency is largely unaffected.

[0003] The more popular traditional close-suction range hoods on the market are those with a smoke shield that can be opened and closed freely with the motion mechanism. The lights of such range hoods are often placed on both sides. When the smoke shield is closed, it also covers the LED light. The light can only be displayed when the smoke shield is opened, so that the lighting device of the range hood cannot be used normally when the range hood is turned off. In order to solve this technical problem, the Chinese utility model patent application with application number 201821587055.7 discloses a range hood with a lighting lamp, which includes a range hood body and a glass panel arranged at the front of the range hood body, an air inlet is provided on the glass panel, and a light-transmitting area is provided on the glass panel. The light-transmitting area is arranged on the periphery of the air inlet, and the lighting lamp assembly is installed on the back side of the glass panel through a mounting bracket, and the lighting lamp assembly is located in the light-transmitting area. However, due to the influence of the glass panel, its lighting effect is not good, which reduces the user experience.

[0004] On the other hand, many existing close-suction oil cups are as long as the entire width of the machine, which is much longer than the oil cups of some European machines. This makes it inconvenient to install and remove the oil cup, especially when there is a lot of oil in the oil cup, as it is easy for the oil to spill due to unbalanced force on the left and right sides.

[0005] Therefore, existing range hoods also need further improvement. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a range hood which can ensure the lighting effect and facilitate the disassembly and assembly of the oil cup in view of the current status of the existing technology.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a range hood comprising:

[0008] chassis;

[0009] The oil cup body is detachably installed at the bottom of the casing;

[0010] The machine also includes a lighting lamp, which is arranged at the bottom of the housing. The rear side of the oil cup body is provided with a mounting recess which is recessed forward for receiving the lighting lamp.

[0011] To facilitate installation and removal of the oil cup in the front-to-back direction, the left-to-right dimensions of the lamp gradually increase from front to back, and the left-to-right dimensions of the mounting recess of the oil cup body also gradually increase from front to back. It is conceivable that the mounting recess of the oil cup body could also be a rectangular opening with equal distances from left to right in the front-to-back direction, and the lamp as a whole could also have a square structure with equal distances from left to right in the front-to-back direction.

[0012] The shape of the lighting lamp is designed to be trapezoidal, with the narrowest part of the two sides of the trapezoid located at the front and the widest part at the rear. The mounting recess of the oil cup body is also designed to be trapezoidal. In this way, the outer contours of the two sides of the lighting lamp can serve as guide blocks for the front and rear installation of the oil cup body. This provides a reference for guidance when installing the oil cup. When the oil cup is pushed flatly to contact the lamp, it can be automatically centered by pushing hard, thereby improving the assembly efficiency of the oil cup.

[0013] As an improvement, the oil cup body is in the shape of a long strip extending left and right, and the lighting lamp is also in the shape of a long strip extending left and right.

[0014] To ensure a good light output, the bottom wall of the lamp extends horizontally, and a light output area is arranged on it for projecting light downward. It is conceivable that the bottom wall of the lamp can also be arranged at an angle relative to the horizontal plane, or be configured with a structure in which multiple planes intersect to serve as the light output surface.

[0015] In order to ensure the aesthetics of the bottom of the range hood and the lighting effect, the bottom wall of the lighting lamp is flush with the bottom wall of the oil cup body.

[0016] As an improvement, the lighting lamp includes a fixing seat, a lampshade, a light source and a light-transmitting plate. The top of the fixing seat has an opening and is connected to the bottom wall of the casing to define an installation chamber. The lampshade is arranged in the installation chamber and together with the bottom wall of the installation chamber defines a lamp cavity for placing the light source. A light-emitting opening is also provided on the bottom wall of the fixing seat, and the light-transmitting plate is arranged at the light-emitting opening.

[0017] In order to simplify the connection structure between the lighting lamp and the bottom wall of the housing, the top edge of the fixing seat is further provided with a flange folded and extended outward, and the flange is connected to the bottom wall of the housing via a fastener.

[0018] After the oil cup is installed, the several flanges of the lighting lamp and the corresponding fasteners are covered by the oil cup body. Looking from the bottom up, the flange structure of the lamp cannot be seen, ensuring the aesthetics of the range hood.

[0019] As an improvement, the light-transmitting plate is a glass plate. The glass plate has a heat-insulating effect and can prevent the light source and other plastic parts of the lighting lamp from being overheated, thereby shortening the life of the lamp.

[0020] Considering that the main cooking operation area of the stove is located in the front and lower part of the oil cup (where the lighting lamp is located), in order to adapt to this and ensure the lighting effect, in the preferred embodiment, the light source is a lamp board with lamp beads, and the side of the lamp board where the lamp beads are located faces front and lower.

[0021] In order to achieve a detachable connection between the oil cup body and the casing, a hook is further provided at the bottom of the casing. The hook has a slot extending forward and backward, and the oil cup body has an insert that can be inserted into and removed from the slot.

[0022] Generally, the hook part can be a one-piece part of an integral design, but in order to facilitate processing and assembly and reduce production costs, the hook includes an upper plate body and a lower plate body detachably connected to the bottom of the upper plate body, and a gap extending front to back is defined between the bottom of the upper plate body and the top of the upper plate body for the insert to be inserted into, and the gap has an opening at least on its front side and left or right side.

[0023] In order to limit the insert of the oil cup body at the rear side and prevent the insert of the oil cup body from falling out, the gap also has an opening on the rear side, and the bottom of the lower plate body is also connected to a reinforcing plate, which is attached to the bottom wall of the lower plate body and bent upward at the rear side to block the limit stop edge of the rear opening of the gap.

[0024] In order to ensure that the insert of the oil cup body is firmly inserted into the slot, the hook is also provided with a snap assembly, which includes:

[0025] The snap button body is movably arranged on the hook and can be inserted into the slot from top to bottom;

[0026] The elastic member acts on the spring buckle body and makes the spring buckle body always have a tendency to move downward and exert pressure on the inserting piece inserted into the slot.

[0027] The above-mentioned elastic member can adopt various existing technologies and may include various elastic elements such as compression springs, torsion springs, and spring leaves. However, in order to better cooperate with the above-mentioned spring buckle body, the hook is defined with a limiting slide for placing the spring buckle body. The lower end of the limiting slide has a through hole that is connected to the slot. The spring buckle body as a whole is a vertically extending rod, and its outer peripheral wall has a limiting stop portion that extends radially outward to limit the position on the upper side of the periphery of the through hole. The elastic member is a spring, and the upper end of the spring is against the inner wall of the limiting slide, and the lower end is against the spring buckle body.

[0028] In order to achieve effective front and rear positioning of the insert by the snap body and facilitate the insert to enter the slot backward and exit the slot forward, the insert has a downwardly concave limiting recess for the lower end of the snap body to be snapped into, and the front side of the lower end of the snap body is constructed with a leading guide slope sloping downward from the front to the rear, and the rear side of the lower end is constructed with a rear guide slope sloping downward from the rear to the front.

[0029] Compared with existing technologies, the present invention offers the following advantages: The lighting lamp and oil cup are both located at the bottom of the housing, arranged along the front and rear sides. This prevents the lighting lamp from being blocked by the smoke shield or other components, allowing it to be used even when the range hood is off, ensuring effective lighting. Furthermore, the rear side of the oil cup body has a recessed recess for accommodating the lighting lamp. When the oil cup body is removed, it engages the lighting lamp to provide a positional stop. This effectively reduces the problem of the oil cup body swaying or shaking, and prevents spillage of oil during removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0037] In the specification and claims of the present invention, directional terms such as "front," "back," "up," "down," "left," "right," "side," "top," and "bottom" are used to describe various exemplary structural parts and components of the present invention. However, these terms are used herein for convenience of description only and are based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different orientations, these directional terms are intended for illustrative purposes only and should not be construed as limiting. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0038] Figures 1-6 A preferred embodiment of the range hood of the present invention is shown. The range hood includes a casing 10 and a centrifugal fan disposed in the casing 10. The casing 10 generally includes a fan frame 11 and a smoke hood 12 disposed at the bottom of the fan frame 11. The inner cavity of the fan frame 11 is connected to the inner cavity of the smoke hood 12. An air inlet is provided on the front side wall of the smoke hood 12, and external smoke can enter the smoke hood 12 through the air inlet. The centrifugal fan is disposed in the fan frame 11. When the centrifugal fan is in operation, negative pressure is generated, and external oil smoke can be sucked into the smoke hood 12 through the air inlet. An oil cup is provided at the bottom of the smoke hood 12. The oil cup 20 is in the shape of a long strip extending left and right, and is used to receive oil stains flowing down from the smoke hood 12. The front portion of the smoke hood 12 is further provided with a smoke deflector 13 that can be pivoted forward and backward relative to the smoke hood 12. The smoke deflector 13 is connected to the main body of the smoke hood 12 via a hinge mechanism. Specifically, the smoke deflector 13 can be pivoted forward to open the aforementioned air inlet and pivoted backward to block and close the aforementioned air inlet. The hinge mechanism for pivoting the smoke deflector 13 can be a conventional hinge mechanism known in the art and will not be described further herein.

[0039] See also Figure 5 and Figure 6 , hooks 35 are provided on both the left and right sides of the bottom wall of the smoke hood 12. The hook 35 in this embodiment includes an upper plate 351, a lower plate 352 detachably connected to the bottom of the upper plate 351, and a reinforcing plate 353 provided at the bottom of the lower plate 352. The left or right part of the bottom of the upper plate 351 has a downwardly protruding boss. After the lower plate 352 and the upper plate 351 are connected in place, the top of the lower plate 352 abuts against the boss. A gap extending forward and backward is defined between the bottom of the upper plate 351 and the top of the upper plate 351 (on the other side corresponding to the above-mentioned boss) into which the insert 21 of the oil cup body 20 is inserted. This gap constitutes the slot 350 of the hook 35.

[0040] The inserts 21 of the oil cup body 20 are typically located at both ends of the body 20 along its length, specifically, extending from the top edge of the body 20 toward the center of the cup. To accommodate the inserts 21 of the oil cup body 20, the slot 350 of the hook 35 is typically open on its front, left, or right sides, while the gap defined by the upper plate 351 and lower plate 352 is open at the rear. To retain the inserts 21 of the oil cup body 20 at the rear and prevent them from falling out, a reinforcing plate 353 is attached to the bottom of the lower plate 352. This reinforcing plate 353 is attached to the bottom wall 11 of the lower plate 352 and folds upward at the rear to correspond with the rearwardly exposed stop edge 3531 that closes the gap. The upper plate 351 , the lower plate 352 and the reinforcing plate 353 can be connected to the bottom of the sliding block 32 via vertically arranged fasteners 38 such as screws, so as to achieve relative sliding installation and fixation of the hook 35 .

[0041] The side opening of the slot 350 of the hook 35 of the mounting assembly located on the left side of the housing 10 is toward the left, while the side opening of the slot 350 of the hook 35 of the mounting assembly located on the right side of the housing 10 is toward the right.

[0042] Combine Figure 4The snap assembly includes a snap body 36 and an elastic member 37. The upper plate 351 of the hook 35 defines a limiting slide 3510 for accommodating the snap body 36. The lower end of the limiting slide 3510 has a through hole 3511 that is in communication with the slot 350. Specifically, the top of the upper plate 351 has an upwardly extending protrusion 3513, and the protrusion 3513 defines the above-mentioned limiting slide 3510. The bottom wall of the smoke hood 12 is provided with an opening for the above-mentioned protrusion 3513 to extend into the smoke hood 12, thereby ensuring that the top surface of the main body of the upper plate 351 is firmly fitted with the bottom wall of the smoke hood 12. The snap body 36 is in the shape of a vertically extending rod as a whole, and its outer peripheral wall has a limiting stop 361 that extends radially outward to be limited to the upper side of the circumference of the through hole 3511. The elastic member 37 is a second spring, also located within the aforementioned limiting slideway 3510. Its upper end abuts against the inner wall of the limiting slideway 3510, while its lower end abuts against the latch body 36. Specifically, a downwardly extending spring positioning hole is defined at the top of the latch body 36. The lower end of the latch body 36 extends through the aforementioned through-hole 35112 and into the slot 350. Under the action of the second spring, the latch body 36 tends to move downward. After the insert 21 of the oil cup body 20 is inserted into the slot 350, the lower end of the latch body 36 applies downward pressure to the insert 21, preventing it from easily slipping forward from the slot 350. More specifically, the insert 21 of the oil cup body 20 has a downwardly recessed retaining recess 210 into which the lower end of the latch body 36 engages. This retaining recess 210 can be a through-and-through opening or a downwardly recessed pit. In a preferred embodiment, the retaining recess 210 is a through-and-through opening. The lower end of the latch body 36 is configured with a guide ramp that slopes downward from front to back or a tapered surface with a gradually decreasing outer diameter from top to bottom. In some embodiments, the lower end of the latch body 36 utilizes a wedge structure with guide ramps at both front and back. The front guide ramp 362 of the wedge structure slopes downward from front to back, while the rear guide ramp 363 slopes downward from back to front. This wedge structure allows the insert 21 of the oil cup body 20 to smoothly insert and exit the slot 350 from front to back, preventing interference between the latch body 36 and the insert 21.

[0043] See also Figure 3 The bottom wall of the fume hood 12 is also equipped with a lighting lamp 3, located behind the oil cup body 20. The oil cup body 20 is a long, strip-shaped structure extending from side to side, and the lighting lamp 3 is also a long, strip-shaped structure extending from side to side. Specifically, the rear side of the oil cup body 20 has a forward-facing mounting recess 22. The shape and size of the mounting recess 22 are substantially the same as those of the lighting lamp 3. When the oil cup body 20 is installed on the fume hood 12 from front to back, the lighting lamp 3 can be correspondingly inserted and stored in the mounting recess 22.

[0044] The left-right dimensions of the lamp 3 gradually increase from front to back, and so do the left-right dimensions of the mounting recess 22 of the oil cup body 20. Specifically, the left sidewall of the lamp 3 slopes leftward from front to back, while the right sidewall slopes rightward from front to back. When viewed from the small upward, the lamp 3 has a trapezoidal structure, and the left and right sidewalls of the mounting recess 22 of the oil cup body 20 are similarly designed. The lamp 3 is designed to be trapezoidal, with the narrowest points of its two sides located at the front and the widest points at the rear. The mounting recess 22 of the oil cup body 20 is also designed to be trapezoidal. This allows the outer contours of the lamp 3 to serve as guide blocks for the front and rear installation of the oil cup body 20. This provides a reference point for the oil cup during installation. When the oil cup is pushed flat against the lamp, a firm push automatically aligns it, improving assembly efficiency.

[0045] The lighting lamp 3 includes a fixing base 31, a lampshade 32, a light source 33 and a light-transmitting plate 34. The top of the fixing base is open and connected to the bottom wall of the housing 10 to define an installation chamber 301. The lampshade 32 is arranged in the installation chamber 301 and together with the bottom wall of the installation chamber 301 define a lamp cavity 302 for placing the light source 33. A light outlet opening 310 is also provided on the bottom wall of the fixing base 31, and a light-transmitting plate 34 is arranged at the light outlet opening 310. The light-transmitting plate 34 can be made of a glass plate. The glass plate has a heat-insulating effect and can prevent the light source 33 and other plastic parts of the lighting lamp 3 from overheating and affecting the life of the lamp. The above-mentioned glass plate also serves as the bottom wall of the lighting lamp 3 and provides a light-emitting area for light to be projected downward. The glass plate extends horizontally and is flush with the bottom wall of the oil cup body 20 to ensure the beauty and refinement of the bottom of the smoke hood 12.

[0046] Taking into account that the main cooking operation area of the stove is located in the front and lower part of the oil cup (where the lighting lamp is located), in order to adapt to this and ensure the lighting effect, in a preferred embodiment, the above-mentioned light source 33 is a lamp board with lamp beads, and the side of the lamp board where the lamp beads are located faces the front and bottom, that is, the lamp board as a whole is tilted downward from front to back.

[0047] The top edge of the mounting base 31 also features an outwardly folded, extending flange 311, which is connected to the bottom wall of the housing 10 via fasteners, such as screws. Once the oil cup is installed, the several flanges 311 of the lamp 3 and the corresponding fasteners are completely covered by the oil cup body 20. When viewed from below, the flanges 311 are invisible, preserving the range hood's aesthetics.

[0048] The lamp 3 and the oil cup are both located at the bottom of the housing 10, arranged along the front and back. This prevents the lamp 3 from being obstructed by the smoke deflector 13 or other components, allowing it to be used even when the range hood is off, ensuring effective lighting. The rear side of the oil cup body 20 features a mounting recess 22 for accommodating the lamp 3. When the oil cup body 20 is removed, it engages the lamp 3 to retain its position. This effectively prevents the oil cup body 20 from swaying or shaking, and avoids spilling oil during removal.
