Description

Technical Field

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

[0002] Existing range hoods generally include a range hood body and an oil cup disposed below the range hood body. The oil cup is used to collect the oil in the range hood body, and the user needs to remove the oil cup to dump the oil. Specifically, the Chinese utility model patent "An oil cup installation structure for a range hood" with application number CN201821055443.0 (authorization announcement number CN208579370U) includes a housing and an oil cup. The oil cup is detachably disposed at the bottom of the housing through an installation assembly. The installation assembly includes a first positioning block, a second positioning block and an elastic member. The first positioning block is disposed at the bottom of the housing and has a first positioning portion at the lower end; the second positioning block is disposed on the inner wall of the oil cup and has a second positioning portion at the upper end; the elastic member enables the second positioning portion to always maintain a tendency to engage with the first positioning portion.

[0003] Another example is the Chinese utility model patent "A Range Hood" with application number CN201821529177.0 (authorization announcement is CN209026905U), which includes a shell and an oil cup. At least two slots extending in the front-to-back direction are arranged at intervals at the bottom of the shell. The oil cup is in the shape of a long strip and is installed at the bottom of the shell and extends in the left-to-right direction. The oil cup has a corresponding plug-in extending in the front-to-back direction and is plugged into the slot; the plug-in is located at a position with a certain distance from the left and right ends of the oil cup and is higher than the upper edge of the rear side of the oil cup.

[0004] Most of the current oil cups are in the shape of long strips, and when the oil cup is installed on the range hood, the vibration of the whole machine may cause the oil cup to shake or even move relative to the range hood. In serious cases, the oil cup will fall off the range hood, causing the oil in the oil cup to spill.

[0005] At the same time, when the oil cup is full of oil and needs to be removed to pour the oil, the oil in the oil cup may spill due to the user pushing and pulling the oil cup back and forth, affecting the user experience. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a mounting structure of an oil cup on a range hood in view of the current status of the prior art, so as to facilitate disassembly and assembly while preventing the oil cup from accidentally moving.

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

[0008] The range hood body, the side of the range hood body facing the user is the front side;

[0009] The oil cup is in the shape of a long strip as a whole, and has plug-in parts at both ends;

[0010] There are at least two mounting parts, which are respectively arranged at the left and right sides of the corresponding oil cup of the range hood body, and each mounting part is provided with a slot extending forward and backward for the plug-in part on the corresponding oil cup to be inserted therein from front to back;

[0011] Features:

[0012] The upper surface of at least one of the plug-in parts is provided with a first recess and a second recess, and the slot where the plug-in part is located is provided with:

[0013] A first stopper is located above the plug-in portion and is inserted into the first recessed portion in an inclined manner downward from the back to the front to limit the plug-in portion from moving backward; and under the action of the plug-in portion moving forward, the first stopper is arranged to move upward and disengage from the first recessed portion;

[0014] A second stopper is located above the plug-in portion and is inserted into the second recessed portion in an inclined manner from front to rear to limit the forward movement of the plug-in portion; and under the action of the plug-in portion moving backward, the second stopper is arranged to move upward and disengage from the second recessed portion;

[0015] The actuating member selectively acts on the first stopper or the second stopper to make the first stopper or the second stopper move upward to release the constraint on the plug-in portion.

[0016] In this way, when the oil cup needs to be installed, the plug-in portion on the oil cup is inserted into the slot of the corresponding mounting member, the actuating member acts on the first stopper to make the first stopper move upward, and then the oil cup is moved from front to back;

[0017] When the oil cup is installed in place, the actuating member releases the effect on the first stopper, and the first stopper and the second stopper are inserted into the corresponding first recess and the second recess to limit the forward and backward movement of the oil cup, thereby reducing the influence of the vibration of the range hood on the oil cup;

[0018] When the oil cup needs to be removed, the actuating member acts on the second stopper to make the second stopper move upward, and then the oil cup is moved forward, which is convenient for operation.

[0019] Preferably, the upper surface of the plug-in portion is in a wave shape with concave portions and convex portions arranged alternately in the front-to-back direction, wherein the two concave portions are the first concave portion and the second concave portion mentioned above;

[0020] And under the action of the plug-in part moving forward, the first stopper is arranged to be able to move up and down and enter and exit each recess one by one; under the action of the plug-in part moving backward, the second stopper is arranged to be able to move up and down and enter and exit each recess one by one.

[0021] In this way, when the oil cup needs to be removed and moved forward, the first stopper moves up and down under the action of the forward-moving plug-in part and enters and exits each recess one by one, and can prevent the oil cup from accidentally moving backward, thereby preventing the user from pushing and pulling the oil cup back and forth, causing the oil in the oil cup to spill and affecting the user experience.

[0022] Preferably, a first elastic member and a second elastic member are further included, which act on the first stopper and the second stopper respectively, so that the first stopper and the second stopper always have a tendency to move downward and be inserted into their respective corresponding recesses. In addition, each stopper can also use its own gravity to always have a tendency to move downward and be inserted into the corresponding recess. The addition of the elastic member in the utility model makes the overall installation structure more stable.

[0023] Preferably, the first stopper is in the shape of a plate and is arranged to be rotatable up and down around its rear side extending left and right or around an axis adjacent to the rear side, the front side of the first stopper is a free edge that matches the recessed portion, and is suspended on the plug-in portion through the first elastic member;

[0024] The second stopper is plate-shaped and is rotatable up and down around its front side extending left and right or an axis adjacent to the front side. The rear side of the second stopper is a free edge that cooperates with the recess and is suspended on the plug-in portion through the second elastic member.

[0025] Preferably, the first elastic member and the second elastic member are springs extending up and down.

[0026] Further, the first stopper is located in front of the second stopper, and the actuating member is located between the first and second stoppers.

[0027] Furthermore, the actuator includes a lever that can rotate forward and backward and a power member that drives the lever to rotate. Driven by the power member, the lever can rotate forward to the lower side of the first stopper to drive the free edge of the first stopper to rotate upward, and can rotate backward to the lower side of the second stopper to drive the free edge of the second stopper to rotate upward.

[0028] Further preferably, a detection member for detecting the number of times the second stopper enters and exits the recess, and a controller electrically connected to the detection member are further included, and the output end of the controller is electrically connected to the power member. In this way, when installing the oil cup, it can be judged whether the oil cup is installed in place according to the number of times the second stopper enters and exits the recess. When the oil cup is installed in place, the controller controls the power member to work and drive the lever to move, so that the lever releases the effect on the first stopper.

[0029] In the above schemes, preferably, the convex portion is in the shape of a triangle with its tip pointing upward, and the above-mentioned concave portion in the shape of a triangle with its tip pointing downward is formed between two adjacent convex portions.

[0030] The triangular structure is conducive to the cooperation between the stopper and the recess, and does not affect the entry and exit of the stopper into the recess.

[0031] Preferably, the angle between the hypotenuse of the triangle and the horizontal plane is 40-50°.

[0032] Compared with the prior art, the utility model has the advantages that: when the oil cup needs to be installed, the plug-in portion on the oil cup is inserted into the slot of the corresponding mounting member, the actuating member acts on the first stopper to make the first stopper move upward, and then the oil cup is moved from front to back;

[0033] When the oil cup is installed in place, the actuating member releases the effect on the first stopper, and the first stopper and the second stopper are inserted into the corresponding first recess and the second recess to limit the forward and backward movement of the oil cup, thereby reducing the influence of the vibration of the range hood on the oil cup;

[0034] When the oil cup needs to be removed, the actuating member acts on the second stopper to make the second stopper move upward, and then the oil cup is moved forward, which is convenient for operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] like Figures 1 to 4 As shown in FIG. 1 , a preferred embodiment of a mounting structure of an oil cup on a range hood of the utility model is shown. The mounting structure comprises a range hood body 1 , an oil cup 2 and a mounting member 3 .

[0041] The range hood body 1 is of the prior art, and the side of the range hood body 1 facing the user is referred to as the front side.

[0042] The oil cup 2 is in the shape of an elongated strip as a whole, and a plug-in portion 21 is provided at its left and right ends. In this embodiment, the upper edge of the left side wall of the oil cup extends to the right to form a folded edge, which is the plug-in portion on the left end of the oil cup. Similarly, the upper edge of the right side wall of the oil cup extends to the left to form a plug-in portion on the right end of the oil cup. The upper surface of the plug-in portion 21 is in the form of a wave in which recesses 211 and protrusions 212 are alternately arranged in the front-to-back direction, and the protrusions 212 are in the form of an isosceles triangle with the tip pointing upward, and the angle between the hypotenuse of the triangle and the horizontal plane is 40 to 50° (the angle can be any value between 40 and 50°, such as 40°, 43°, 45°, 46°, 50°, etc.), and the above-mentioned recess 211 with the tip pointing downward is formed between two adjacent protrusions 212. For details, please refer to Figure 2 , 3 .

[0043] There are two mounting members 3, which are respectively arranged at the left and right sides of the range hood body 1 corresponding to the oil cup 2. Each mounting member 3 is provided with a slot 30 extending forward and backward for the corresponding plug-in portion 21 on the oil cup 2 to be inserted therein from front to rear, and each slot 30 is provided with a first stopper 31, a second stopper 32, an actuating member 33, a first elastic member 34 and a second elastic member 35.

[0044] Among them, the first stopper 31 is in the shape of a plate, and is arranged above the plug-in part 21 so as to be able to rotate up and down around its rear side extending left and right or an axis adjacent to the rear side, and the front side of the first stopper 31 is a free edge cooperating with the recess 211, and is suspended on the plug-in part 21 by a first elastic member 34, and the first elastic member 34 is a spring extending up and down, which acts on the first stopper 31 and makes the first stopper 31 always rotate downward so that the free edge of the first stopper 31 is tilted downward from back to front and inserted into one of the recesses 211 (referred to as the first recess) to limit the backward movement of the plug-in part 21; and under the action of the plug-in part 21 moving forward, the first stopper 31 is arranged to be able to rotate up and down and enter and exit each recess 211 one by one.

[0045] The second stopper 32 is plate-shaped and is arranged above the plug-in portion 21 so as to be able to rotate up and down around the front side edge or the axis adjacent to the front side edge extending left and right, and is located at the rear side of the first stopper 31. The rear side edge of the second stopper 32 is a free edge that matches the recess 211, and is suspended on the plug-in portion 21 through the second elastic member 35. The second elastic member 35 is a spring extending up and down, which acts on the second stopper 32 and makes the second stopper 32 always rotate downward so that the free edge of the second stopper 32 is inserted downwardly in another recess 211 (referred to as the second recess, which is located at the rear side of the first recess) from front to back to limit the plug-in portion 21 from moving forward; and under the action of the plug-in portion 21 moving backward, the second stopper 32 is arranged to be able to rotate up and down and enter and exit each recess 211 one by one.

[0046] In this embodiment, during the forward and backward movement of the plug-in portion 21, the first and second stoppers can rotate around their respective axes within a certain angle range (an angle of 40 to 50° with the horizontal plane).

[0047] The actuating member 33 is located between the first and second stoppers, and can selectively act on the first stopper 31 or the second stopper 32, so that the first stopper 31 or the second stopper 32 rotates upward to release the constraint on the plug-in portion 21. Specifically, the actuating member 33 includes a lever 331 that can rotate forward and backward, and a power member 332 that drives the lever 331 to rotate. The lever 331 can rotate forward to the lower side of the first stopper 31 under the drive of the power member 332 to drive the free edge of the first stopper 31 to rotate upward, and can rotate backward to the lower side of the second stopper 32 to drive the free edge of the second stopper 32 to rotate upward. At the same time, the lever 331 can rotate to the central position extending downward under the drive of the power member 332. At this time, the lever 331 releases the constraints on the first and second stoppers at the same time, and the lever 331 does not affect the forward and backward movement of the oil cup.

[0048] When the oil cup 2 needs to be installed, the plug-in portion 21 on the oil cup 2 is inserted into the slot 30 of the corresponding mounting member 3, and the actuating member 33 acts on the first stopper 31 to make the first stopper 31 rotate upward, and then the oil cup 2 is moved from front to back;

[0049] When the oil cup is installed in place, the actuating member 33 releases the effect on the first stopper 31. At this time, the first stopper 31 and the second stopper 32 are inserted into the corresponding first recess and the second recess to limit the forward and backward movement of the oil cup 2, thereby reducing the influence of the vibration of the range hood on the oil cup 2.

[0050] When the oil cup 2 needs to be removed, the actuating member 33 acts on the second stopper 32 to move the second stopper 32 upward, and then the oil cup 2 is moved forward, which is convenient for operation.

[0051] In order to determine whether the oil cup 2 is installed in place, the present embodiment further includes a detection member for detecting the number of times the second stopper 32 enters and exits the recess 211, and a controller electrically connected to the detection member, and the output end of the controller is electrically connected to the power member 332. In this way, when the oil cup is installed, it can be determined whether the oil cup is installed in place according to the number of times the second stopper 32 enters and exits the recess. When the oil cup is installed in place, the controller controls the power member 332 to work and drives the lever 331 to move, so that the lever 331 releases the effect on the first stopper 31.

[0052] The detection member of this embodiment can directly detect the number of times the second stopper 32 enters and exits the recess 211 , and can also indirectly detect the number of times the second stopper 32 enters and exits the recess 211 by detecting the number of times the second elastic member 35 extends and retracts up and down.

[0053] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
