Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to an oil cup mounting structure of a range hood. Background Art

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It operates based on the principles of fluid dynamics. A centrifugal fan installed inside the range hood generates negative pressure suction, drawing fumes from beneath the range hood into the centrifugal fan. The fan accelerates the airflow and directs it outside, thus purifying the kitchen environment. As the range hood discharges fumes, much of the grease is separated. Therefore, a grease collection cup is often installed at the bottom of the range hood to collect the separated grease and dispose of it when it reaches a certain level.

[0003] Currently, most range hood oil cups on the market are installed using a plug-in system at the rear of the range hood, near the wall. The oil cup is elongated with legs along its length. The legs are inserted into hooks on the bottom of the range hood to secure the oil cup. This type of oil cup mounting structure is disclosed in Chinese Utility Model Patent Application No. CN201621027418.2 (Granted Publication No. CN206073197U).

[0004] However, the existing oil cup installation structure still has certain shortcomings. Since the oil cup hook is fixedly installed and cannot be adjusted forward and backward, the position of the oil cup is fixed after it is installed. If the wall of the user's home is uneven, the distance between the oil cup and the wall will be too close. When the range hood is running, vibration will be generated between the oil cup and the wall, which greatly reduces the user experience.

[0005] Therefore, the oil cup mounting structure of the existing range hood needs further improvement. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an oil cup installation structure for a range hood in view of the current status of the existing technology, in which the front and rear positions of the oil cup relative to the housing of the range hood are adjustable.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: an oil cup mounting structure for a range hood, comprising:

[0008] chassis;

[0009] The oil cup body is detachably connected to the bottom of the casing;

[0010] Also included is a mounting assembly disposed at the bottom of the housing, the mounting assembly comprising:

[0011] A fixing seat, provided at the bottom of the housing;

[0012] The sliding block is arranged on the fixing seat in a manner that it can move forward and backward relative to the fixing seat and its position is adjustable. The oil cup body is connected to the sliding block and can move forward and backward with the sliding block.

[0013] In order to achieve the front and rear sliding limit of the fixed seat and the sliding block, a movable groove for placing the sliding block is defined on the fixed seat, and one of the side walls of the sliding block and the side wall of the movable groove is provided with a limiting sliding groove extending forward and backward, and the other is provided with a corresponding limiting protrusion.

[0014] Generally, the user or operator can directly move the sliding block to adjust the front and rear position. However, considering that the range hood is in a fully assembled state, the sliding block will be hidden, that is, it will not be easily exposed and touched. Therefore, in order to facilitate the user to adjust the front and rear position of the sliding block, the fixing base is further provided with an axial hole extending front and rear and penetrating from the outside to the movable groove. The mounting assembly further includes:

[0015] an adjusting screw axially movably disposed in the axial hole of the fixing seat, the outer end of the adjusting screw having a first stopper extending radially outward for being positioned outside the peripheral edge of the axial hole, and the inner end of the adjusting screw being threadedly connected to the sliding block;

[0016] The first elastic member acts on the sliding block and enables the sliding block to always have a tendency to move along the front-back direction toward the side away from the shaft hole of the fixing seat.

[0017] The above-mentioned first 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 adjusting screw, the first elastic member is a first spring, which is sleeved on the adjusting screw and rests between the sliding block and the side wall of the movable groove.

[0018] Taking into account that the fixing seat and components such as the adjusting screw arranged thereon are generally hidden in the casing, in order to facilitate the operator to adjust the adjusting screw, the fixing seat is arranged in the casing, the outer end of the adjusting screw faces the rear side, and an operating hole is opened on the rear side wall of the casing in the area opposite to the outer end of the adjusting screw.

[0019] In order to facilitate the detachable connection of the oil cup body, a hook is further provided at the bottom of the sliding block. 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.

[0020] 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.

[0021] 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.

[0022] In order to ensure that the inserting piece of the oil cup body is securely inserted into the slot, the hook is further provided with a snap assembly that can extend into the slot and apply pressure to the inserting piece.

[0023] In order to simplify the structure of the snap assembly, the snap assembly includes:

[0024] The snap button body is movably arranged on the hook and can be inserted into the slot from top to bottom;

[0025] The second 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.

[0026] The above-mentioned second 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 second limiting stop portion extending radially outward to limit the position on the upper side of the circumference of the through hole. The second elastic member is a second spring. The upper end of the second spring is against the inner wall of the limiting slide, and the lower end is against the spring buckle body.

[0027] In order to enable the insert of the oil cup body to be smoothly inserted into the slot from front to back and avoid interference between the spring buckle body and the insert, the lower end of the spring buckle body is constructed with a guide inclined surface that tilts downward from front to back or a conical surface with a gradually smaller outer diameter from top to bottom.

[0028] In order to achieve effective front and rear positioning of the insert by the snap button body, the insert is provided with a downwardly concave limiting recess for the lower end of the snap button body to be snapped into.

[0029] In order to make the oil cup body fit the bottom wall of the casing as closely as possible and ensure the refinement of the oil cup mounting structure, a clearance opening extending from top to bottom is opened on the bottom wall of the casing. The fixing seat is arranged in the casing and at the position of the clearance opening. The bottom of the movable groove on the fixing seat has an opening opposite to the clearance opening. A hook is also provided at the bottom of the sliding block. The hook has a slot extending forward and backward. At least the part of the hook where the slot is located is exposed through the clearance opening of the casing.

[0030] In order to adapt to the long strip-shaped oil cup and ensure the reliability of the oil cup installation, the installation component has two groups arranged at intervals on the left and right. The oil cup body as a whole is a long strip extending left and right, and its two ends in the length direction have plugs that can be inserted into the slots of the two groups of installation components.

[0031] Compared with the existing technology, the advantages of the present invention are as follows: the oil cup body is connected to the bottom of the casing through an installation component, wherein the installation component includes a fixed seat and a sliding block, wherein the sliding block can move forward and backward relative to the fixed seat to adjust the front and rear position. In this way, after the oil cup body is installed in place, its position is also adjustable front and back. If the wall of the user's home is uneven, the oil cup can be moved forward to avoid vibration between the oil cup and the wall when the range hood is running, thereby improving the user experience.

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.

[0042] Figures 1-8 A preferred embodiment of the oil cup mounting structure for a range hood according to the present invention is shown. The range hood comprises a housing 10 and a centrifugal fan mounted within the housing 10. The housing 10 generally comprises a fan frame and a fume hood mounted at the bottom of the fan frame. The interior of the fan frame communicates with the interior of the fume hood. An air inlet is defined on the front sidewall of the fume hood, through which external smoke enters the hood. The centrifugal fan is mounted within the fan frame. When in operation, the centrifugal fan generates negative pressure, drawing external oil smoke into the hood through the air inlet. The bottom of the fume hood is provided with an oil cup. This long, strip-shaped cup extends left and right, and is used to collect oily dirt that flows down from the fume hood. A smoke shield 13 is also provided at the front of the fume hood, which can pivot forward and backward relative to the hood. The shield 13 is connected to the main body of the fume hood via a hinged mechanism. Specifically, it can be pivoted forward to open the air inlet and backward to block and close it. The hinge motion mechanism for driving the smoke baffle 13 to deflect can adopt a conventional hinge motion mechanism in the prior art, which will not be described in detail here.

[0043] The oil cup body 20 is a long strip extending left and right, and is connected to the bottom of the housing 10 through a mounting assembly. Specifically, the mounting assembly includes a fixing seat 31, a sliding block 32, an adjusting screw 33, a first elastic member 34, a hook 35 and a snap assembly.

[0044] The bottom wall 11 of the housing 10 is provided with a clearance opening 110. The fixing seat 31 is provided in the housing 10 and is arranged at the location of the clearance opening 110. The fixing seat 31 has a movable groove 310 for accommodating the movable block. The bottom of the movable groove 310 is open and faces the clearance opening 110. Figure 4As shown, the left and right sides of the fixing base 31 have connecting parts, and the screws 39 can pass through the bottom wall 11 of the casing 10 from the outside of the casing 10 to connect with the connecting parts on the left and right sides of the fixing base 31, thereby firmly fixing the fixing base 31 above the clearance opening 110 of the bottom wall 11 of the casing 10.

[0045] The sliding block 32 is movably disposed in the movable groove 310 of the fixed base 31. Specifically, the left and right side walls of the movable groove 310 of the fixed base 31 have limiting grooves 311 extending forward and backward, and the left and right side walls of the movable block are correspondingly provided with limiting protrusions 321 adapted to the above-mentioned limiting grooves 311.

[0046] See also Figure 5 The hook 35 is provided at the bottom of the sliding block 32 and is capable of moving forward and backward along with the sliding block 32. The hook 35 in this embodiment comprises 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 portion of the bottom of the upper plate 351 has a downwardly projecting boss. When the lower plate 352 is coupled to the upper plate 351, 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 side opposite the boss) into which the insert 21 of the oil supply cup body 20 is inserted. This gap constitutes the slot 350 for the hook 35.

[0047] 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 .

[0048] like Figure 3As shown, in order to facilitate the insertion of the insert 21 of the oil cup body 20 into the slot 350 of the hook 35 and to ensure that the oil cup body 20 fits as closely as possible with the bottom wall 11 of the casing 10 after being installed, thereby improving the refinement of the product, the fixing seat 31 and the sliding block 32 provided on the fixing seat 31 are basically located inside the casing 10, that is, above the plane where the clearance opening 110 of the bottom wall 11 of the casing 10 is located, and the hook 35 provided at the bottom of the sliding block 32 or at least a part of the hook 35 (the part where the slot 350 is located) is exposed downward through the clearance opening 110 of the casing 10.

[0049] 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.

[0050] The snap assembly includes a snap body 36 and a second elastic member 37. The upper plate 351 of the hook 35 defines a retaining slide 3510 for accommodating the snap body 36. The lower end of the retaining slide 3510 has a through hole 3511 that intersects the slot 350. Specifically, the top of the upper plate 351 has an upwardly extending protrusion that defines the retaining slide 3510. Correspondingly, the sliding block 32 has an opening 320 for inserting the protrusion, thereby ensuring a secure fit between the top surface of the upper plate 351 and the bottom surface of the sliding block 32. The snap body 36 is generally in the shape of a vertically extending rod. Its outer peripheral wall includes a second retaining stop 361 that extends radially outward and is retained on the upper side of the circumference of the through hole 3511. The second 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 3511 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 out of 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 a preferred embodiment, the lower end of the latch body 36 utilizes a wedge structure with guide ramps at both front and back. The front guide ramp 360a of the wedge structure slopes downward from front to back, while the rear guide ramp 360b 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.

[0051] Considering the fully assembled state of the range hood, the aforementioned fixed base 31 and sliding block 32 are concealed, that is, not easily exposed and accessible. Therefore, to facilitate user adjustment of the fore-and-aft position of the sliding block 32, the fixed base 31 further includes an axial hole 312 extending forward and backward and extending from the outside to the movable groove 310. An adjusting screw 33 extends forward and backward and is axially movable through the axial hole 312 of the fixed base 31. The outer end of the adjusting screw 33 includes a first stop 331 extending radially outward to be retained outside the peripheral edge of the axial hole 312. The inner end of the adjusting screw 33 is threadedly connected to the sliding block 32. A first elastic member 34, a first spring, is sleeved on the adjusting screw 33 and abuts between the sliding block 32 and the sidewall of the movable groove 310. Under the elastic force of the first spring, the sliding block 32 always tends to move in the fore-and-aft direction toward the side away from the axial hole 312 of the fixed base 31. In the preferred embodiment, the outer end of the adjustment screw 33 faces rearward, and the sliding block 32, under the action of the first spring, always tends to move forward. Rotating the adjustment screw 33 causes the sliding block 32 to move forward and backward, thereby changing the forward and backward position of the sliding block 32 relative to the fixed base 31 and simultaneously changing the compression of the first spring.

[0052] Considering that the fixing base 31 and the adjusting screw 33 mounted thereon are generally concealed within the housing 10, an operating hole 120 is defined on the rear side wall 12 of the housing 10 in an area opposite the outer end of the adjusting screw 33 to facilitate adjustment by the operator. The operator can insert a tool through the operating hole 120 to rotate and adjust the adjusting screw 33.

[0053] The oil cup body 20 of this embodiment is connected to the bottom of the casing 10 through an installation component, wherein the installation component includes a fixed seat 31 and a sliding block 32, wherein the sliding block 32 can move forward and backward relative to the fixed seat 31 to adjust the front and rear position. In this way, after the oil cup body 20 is installed in place, its position is also adjustable front and rear. If the wall of the user's home is uneven, the oil cup can be moved forward to avoid vibration between the oil cup and the wall when the range hood is running, thereby improving the user experience.
