Description

TECHNICAL FIELD

[0001] The utility model relates to range hood technical field especially, relates to a range hood's oil cup mounting structure and range hood. BACKGROUND

[0002] Range hood is a kind of kitchen appliance that purifies kitchen environment.The oil cup of existing range hood is generally arranged at the bottom of the casing for receiving oil stains flowing from the casing.Most of the oil cups of range hood are generally arranged exposedly, and the outer wall of the oil cup is easy to adhere oil, which affects the appearance.Therefore, some range hoods hide the oil cup in the casing, such as the Chinese utility model patent application No.CN201020535523.3 (authorized publication No.CN201795548U) discloses a range hood oil collecting structure capable of hiding the oil cup, which comprises an oil cup and an oil leakage opening arranged on the casing, and an oil cup bracket is fixed below the casing, the oil cup bracket has a chamber with an open front end, an opening corresponding to the oil leakage opening of the casing is formed on the top wall of the chamber, the oil leakage opening falls within the range of the opening, a decorative front plate is fixed to the lower part of the casing, and an inlet matching the shape and size of the oil cup is formed on the decorative front plate, the oil cup enters the chamber of the oil cup bracket after passing through the inlet of the decorative front plate and is placed in the chamber, and the opening completely falls within the range of the oil inlet on the upper part of the oil cup.

[0003] However, the above-mentioned oil cup mounting structure still has some deficiencies, since the oil cup is installed into the chamber in a front-rear mounting manner, it is difficult for the user to balance the forces applied to the left and right sides during the process of dismounting the oil cup, so that the oil cup is prone to jamming due to the deflection of the oil cup, which makes the process of taking out the oil cup relatively difficult, especially when the oil liquid in the oil cup is relatively large, the oil cup is relatively heavy, and it is more difficult to balance the forces applied to the left and right sides of the oil cup (forces applied in the front-rear direction) when the oil cup needs to be held upwards, which reduces the user experience.

[0004] Therefore, the existing range hood still needs to be further improved. UTILITY MODEL CONTENTS

[0005] The first technical problem to be solved by the utility model is to provide an oil cup mounting structure of a range hood, which facilitates the dismounting of the oil cup and avoids the problem of jamming.

[0006] The second technical problem to be solved by the utility model is to provide a range hood adopting the oil cup mounting structure.

[0007] The technical solution adopted by the utility model to solve the first technical problem is as follows:

[0008] An oil cup mounting structure of a range hood, comprising:

[0009] a casing;

[0010] The oil cup body has a connecting portion;

[0011] The bottom of the casing is provided with a mounting opening, the oil cup body can enter into the casing through the mounting opening, the casing is provided with a fixing seat, and the connecting portion of the oil cup body is connected with the fixing seat of the casing through the press-pull type buckle assembly.

[0012] The above-mentioned "the oil cup body can enter into the casing through the mounting opening" can be understood as that after the oil cup body is installed in place, it is completely embedded into the casing and invisible from the front, or can be understood as that after the oil cup body is installed in place, the oil cup body also has part of the outer exposure of the mounting opening of the casing, that is, the lower part of the oil cup body is visible in the horizontal direction view angle, but since the normal standing view angle of the user is higher than the position of the bottom wall of the casing, the user cannot see the oil cup in the natural standing state.

[0013] After the oil cup is installed in place, the oil cup is hidden in the casing, which ensures the overall aesthetics of the range hood. The connecting portion of the oil cup body and the fixing seat of the casing are connected through the press-pull type buckle assembly, wherein the oil cup is arranged at the bottom of the casing in an up-down dismounting manner. In the process of dismounting the oil cup, the user presses the oil cup upward, the oil cup is pulled downward, and the oil cup is naturally separated from the mounting opening of the bottom of the casing under the action of its own gravity. Since the oil cup is separated from the mounting opening by its own gravity, the dismounting process of the oil cup is not prone to jamming problems, is more convenient and easy to operate, and improves the user experience.

[0014] Generally, the press-pull type buckle assembly can adopt existing cantilever press buckle, ball head-slot press buckle, bilateral symmetric press buckle and the like. In order to be compatible with the installation of the oil cup, preferably, the connecting portion of the oil cup body is an extension column extending upward from the top of the oil cup body, the upper end of the extension column is provided with a ball head portion with a limiting step, the fixing seat is provided with a clasp main body capable of locking and unlocking the ball head portion of the extension column, and the extension column and the clasp main body jointly constitute the press-pull type buckle assembly. The press-pull type buckle assembly can fix the oil cup body and the casing when pressed for the first time, and pull the oil cup body downward from the mounting opening of the casing when pressed again.

[0015] In order to further ensure the firmness of the installation of the oil cup body, the oil cup body is in the shape of a long strip, the press-pull type buckle assembly has two groups, and the two ends of the oil cup body in the length direction are connected with the casing through the press-pull type buckle assembly.

[0016] In order to better guide the oil on the casing to the oil cup, the top of the oil cup body is open, and the position above the oil cup in the casing is provided with an oil receiving disc for receiving the oil flowing down from above, and the oil receiving disc is provided with oil leakage holes for allowing the oil to fall into the oil cup body.

[0017] As an improvement, a centrifugal fan is arranged in the casing and located above the oil receiving disc.

[0018] As an improvement, the front of the casing is further provided with a panel support which is inclined rearward from top to bottom as a whole, the top side edges and left and right side edges of the panel support are connected with the casing, and the bottom side edge of the panel support extends to the position of the oil receiving disc. When the range hood is in operation, the oil fume or water vapor will impact on the panel support, the generated oil stains will flow down along the surface of the panel support and enter the oil receiving disc below, and finally flow into the oil cup.

[0019] In order to smoothly guide the oil stains on the panel support (including the oil stains on the front side and rear side) to the oil receiving disc, the front side edge of the oil receiving disc is provided with a bent plate extending forward and upward, the bottom side edge of the panel support is located above the bent plate and is arranged in a spaced manner with the bent plate.

[0020] In order to avoid the oil stains on the front side of the panel support from contacting the lower panel when flowing downward and dripping on the cooking table along the lower panel, the lower part of the casing is provided with a lower panel, and the middle part and the lower part of the panel support are recessed towards the casing, so that there is an oil passing gap between the lower panel and the lower part of the panel support.

[0021] In order to facilitate the maintenance or replacement of the press-pull type buckle assembly and other components located at the rear side of the lower panel, the lower panel comprises a panel body and a mounting support arranged on the back of the panel body, and the mounting support is detachably connected to the casing.

[0022] In order to facilitate processing and reduce production cost, the mounting port of the bottom of the casing is provided with an upwardly extending flange as the fixing seat.

[0023] In order to increase the strength of the flange and avoid affecting the accuracy of the press installation of the oil cup body due to deformation, a reinforcing plate is further arranged between the flange and the bottom side wall of the casing.

[0024] In order to further improve the appearance of the range hood and facilitate wiping and cleaning, the bottom of the oil cup body is flush with or smoothly transitions with the bottom of the casing when the oil cup body enters the casing and is installed in place.

[0025] The utility model solves the technical scheme that the second technical problem adopts: a range hood, including the oil cup installation structure of above-mentioned range hood.

[0026] Compared with the prior art, the utility model has the advantages that: after the oil cup is installed in place, the oil cup is hidden in the shell, ensuring the overall appearance of the range hood. The connecting part of the oil cup body and the fixing seat of the shell are connected through a press-out type buckle assembly, wherein the oil cup is arranged at the bottom of the shell in an up-down disassembly manner. During disassembly of the oil cup, the user presses the oil cup upward, the oil cup is popped downward, and is naturally separated from the mounting opening at the bottom of the shell under the action of its own gravity. Since the oil cup is separated from the mounting opening by its own gravity, the disassembly process of the oil cup is not prone to jamming, is more convenient and easy to operate, and improves the user experience.

[0034] The utility model will be further described in detail below in combination with the embodiment of the drawings.

[0035] In the description and claims of the present application, terms are used to describe various example embodiments of the application. These terms are used only to facilitate description of the example embodiments of the application, and are in no way intended to limit or restrict the scope of the application. For example, the terms "front," "back," "upper," "lower," "left," "right," "side," "top," "bottom," "under," "over," and the like are used only to denote the orientation of elements on the drawings. The application can be in various orientations (for example, rotated 90 degrees or in a flipped orientation) and terms are used only to describe example embodiments and not to limit or restrict the present application.

[0036] Figures 1-7 An oil cup mounting structure of a range hood and a preferred embodiment of the range hood of the present application are shown. The range hood comprises a casing 1 and a centrifugal fan 20 arranged in the casing 1. An air inlet is formed in a front side wall (i.e. a panel support 30) of the casing 1, and external smoke can enter the casing 1 through the air inlet. The centrifugal fan 20 is arranged in the casing 1, and generates negative pressure when operating, so that external oil fume can be sucked into the casing 1 through the air inlet. An oil screen is arranged at the air inlet of the casing 1 for filtering oil fume. An oil cup is arranged at the bottom of the casing 1, and is in the form of a long strip extending leftward and rightward, and is used for receiving oil stains flowing down from the casing 1. A smoke baffle 14 capable of deflecting forward and backward relative to the casing 1 is further arranged at the upper portion of the front side of the casing 1, and is connected to the main body of the casing 1 through a hinge movement mechanism, and can specifically deflect forward to open the air inlet and deflect backward to block the air inlet. The hinge movement mechanism for driving the smoke baffle 14 to deflect can adopt a conventional hinge movement mechanism in the prior art, and will not be described herein.

[0037] Referring to Figure 2 , the bottom of the casing 1 is provided with a mounting opening 10 extending along the left-right direction. The casing 1 is provided with a fixing seat 11 at the left and right sides corresponding to the mounting opening 10, and the left and right sides of the main body 5 of the oil cup are provided with upwardly extending connecting portions. The main body 5 of the oil cup can enter the casing 1 through the mounting opening 10, and the connecting portions of the left and right sides of the main body 5 of the oil cup are connected to the fixing seats 11 of the left and right sides of the bottom of the casing 1 through press-pull type buckle assemblies.

[0038] Referring to Figure 4 , the left and right side edges of the mounting opening 10 of the bottom of the casing 1 are each provided with an upwardly extending flange, and the flange is the fixing seat 11. A reinforcing plate 12 is further arranged between the flange and the side wall of the bottom of the casing 1, and is arranged obliquely and abuts between the flange and the bottom wall of the casing 1, so as to increase the strength of the flange and avoid affecting the accuracy of the press-fitting of the main body 5 of the oil cup due to deformation.

[0039] Referring to Figure 4 and Figure 7The connecting part of the oil cup body 5 is an extension post 51 extending upward from the top of the oil cup body 5. The upper end of the extension post 51 is set as a ball head 510 with a limiting step. The fixing base 11 is provided with a snap-fit ​​body 13 that can lock and unlock with the ball head 510 of the extension post 51. The extension post 51 and the snap-fit ​​body 13 together constitute a press-to-pop type snap-fit ​​assembly. The press-to-pop type snap-fit ​​assembly can fix the oil cup body 5 and the housing 1 when pressed for the first time, and push the oil cup body 5 downward from the mounting port 10 of the housing 1 when pushed again. The structure and specific working process of the press-to-pop type snap-fit ​​assembly are existing technologies and will not be described in detail here.

[0040] See Figure 3 and Figure 4 Inside the housing 1, above the oil cup, is an oil receiving tray 21 for collecting the oil flowing down from above. The oil receiving tray 21 has a disc structure that is high around the edges and low in the middle. Specifically, the centrifugal fan 20 inside the housing 1 is located above the oil receiving tray 21, and the oil accumulated on the outer wall or inside the volute of the centrifugal fan 20 will also fall into the oil receiving tray 21 below. A drain hole 210 is provided in the middle (i.e., the lowest position) of the oil receiving tray 21 for the oil to fall into the oil cup body 5. The top of the oil cup body 5 is open, generally collecting the oil falling from the drain hole 210.

[0041] The smoke baffle 14 on the upper front side of the housing 1 is inclined when closed, specifically from top to bottom and backward. The lower front side of the housing 1 is provided with a lower panel 4, which is also inclined from top to bottom and backward. That is, when the range hood is turned off, the lower edge of the smoke baffle 14 and the upper edge of the lower panel 4 are joined together to form a complete panel structure.

[0042] The front of the housing 1 is also provided with a panel support 30 that is inclined from top to bottom and backward. The panel support 30 is located inside the smoke baffle 14 and the lower panel 4. The top side 31 and the left and right side 32 of the panel support 30 are connected and fixed to the housing 1, while the bottom side of the panel support 30 extends to the location of the oil receiving tray 21. Specifically, the front edge of the oil receiving tray 21 has a bent plate 211 extending forward and upward. The bottom side 33 of the panel support 30 is located above the bent plate 211 and is spaced apart from the bent plate 211. The inclination direction of the bottom side 33 of the panel support 30 is basically the same as the inclination direction of the bent plate 211 of the oil receiving tray 21. The gap between the two does not need to be too large in order to avoid smoke from entering the housing 1 through the gap between the two.

[0043] When the range hood is running, oil fumes or water vapor impact the panel support 30, and the resulting oil flows down the surface of the panel support 30 into the oil collection tray 21 below, eventually converging into the oil cup. In this embodiment, the middle and lower parts of the panel support 30 are recessed towards the housing 1, thereby forming an oil guiding path that facilitates the flow of oil to the bottom of the panel support 30. The pressed structure of the panel support 30 recessed towards the housing 1 ensures the strength of the panel support 30 and also forms a smoke-collecting recessed area with a smoke-collecting space, reducing the escape of oil fumes to the left and right sides. The middle of the lower plate 4 corresponds to the formation of an air inlet 300, and an oil filter 301 is installed at the air inlet 300.

[0044] The recessed structure design of the lower part of the panel support 30 creates a corresponding oil passage gap 43 between the lower panel 4 and the lower part of the panel support 30. This prevents oil stains on the front side of the panel support 30 from contacting the lower panel 4 when flowing downwards and dripping onto the stovetop along the lower panel 4.

[0045] See Figure 6 The lower panel 4 includes a panel body 41 and a mounting bracket 42 located on the back of the panel body 41. The panel body 41 is a glass plate, and the mounting bracket 42 can be glued to the back of the panel body 41. The mounting bracket 42 is detachably connected to the housing 1, which facilitates the inspection or replacement of components such as the press-to-pop buckle assembly located on the rear side of the lower panel 4.

[0046] The top left and right sides of the mounting bracket 42 have limiting hooks 421, and the left and right sides of the front of the housing 1 have corresponding slots 101 for engaging with the limiting hooks. The bottom of the mounting bracket 42 also has a support flange 422 extending to the right, and the support flange 422 has screw holes. When installing the lower panel 4, the limiting hooks 421 of the mounting bracket 42 can be engaged with the slots 101 of the housing 1 first, and then the support flange 422 of the mounting bracket 42 can be placed against the bottom front side of the housing 1, and the two can be fixed with screws.

[0047] After the oil cup body 5 is installed in place, it can be completely embedded inside the housing 1 and not visible from the front. Alternatively, it can be understood that after the oil cup body 5 is installed in place, a portion of it protrudes from the mounting opening 10 of the housing 1. That is, from a horizontal perspective, the lower part of the oil cup body 5 is visible, but since the user's normal standing perspective is higher than the bottom wall of the housing 1, the oil cup is not visible when the user is standing naturally. In a preferred embodiment, to further improve the aesthetics of the range hood and facilitate cleaning, when the oil cup body 5 is installed in the housing 1, the bottom of the oil cup body 5 is flush with or smoothly transitions to the bottom of the housing 1.

[0048] After the oil cup is installed, it is hidden inside the housing 1, ensuring the overall aesthetics of the range hood. The connecting part of the oil cup body 5 is connected to the fixing seat 11 of the housing 1 by a press-and-pop buckle assembly. The oil cup is installed at the bottom of the housing 1 in a top-and-bottom detachable manner. During the process of removing the oil cup, the user presses the oil cup upward, and the oil cup pops downward and naturally detaches from the mounting port 10 at the bottom of the housing 1 under its own weight. Since the oil cup is ejected from the mounting port 10 by its own weight, the removal process of the oil cup is less prone to jamming, making it more convenient and easier to operate, and improving the user experience.
