Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an oil net installation structure and a range hood. Background Art

[0002] In the field of range hoods, the oil screen is a vital component of the range hood. Its main function is to filter and separate the oil smoke in the flue and reduce the amount of grease entering the exhaust system.

[0003] Existing range hoods have an air inlet on the hood, and the oil net is installed at the air inlet. The oil net is generally fixed and installed with screws or buckles, and the oil net needs to be aligned with the hood during installation; or a front installation port and a rear installation slot are set at the air inlet, and during installation, the rear end of the oil net is installed in the rear installation slot, and the front end of the oil net is installed in the front installation port. When installing the above two solutions, the user needs to look directly at the air inlet position to ensure that the oil net is installed in place, but in some cases, especially in dark environments or when the installation position is relatively hidden due to the obstruction of the smoke collection structure of the range hood, it is difficult for the user to correctly perform the above alignment and installation operations. Utility Model Content

[0004] The purpose of the utility model is to provide an oil net installation structure and a range hood, which solves the technical problem in the prior art that in a dark environment or due to the obstruction of the gathering structure of the range hood, the installation position is relatively hidden, making it difficult for the user to correctly perform the operations of aligning and installing the oil net.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides an oil screen installation structure, comprising an installation slot arranged on a smoke collecting hood, an air inlet communicating with a smoke collecting cavity formed inside the smoke collecting hood is arranged at the bottom of the installation slot, the width of the air inlet gradually decreases from front to back, and a limiting structure is arranged at the rear end of the air inlet;

[0007] An oil net is installed at the installation groove, and a limiting fold is provided at the rear end of the oil net body of the oil net. The limiting fold can extend into the air inlet, and the air inlet can guide the limiting fold to move from front to rear so that the limiting fold abuts against the limiting structure to guide the oil net into place.

[0008] The installation structure of the oil net is achieved by gradually reducing the width of the air inlet from front to back, and providing a limiting structure at the rear end of the air inlet. The limiting folded edge at the rear end of the oil net body can extend into the air inlet, and the air inlet can guide the limiting folded edge to move from front to back so that the limiting folded edge and the limiting structure are abutted against each other, thereby guiding the oil net to be installed in place, so that the oil net can be installed in the installation groove without additional alignment operations, thereby being suitable for dark environments or situations where the oil net is inconvenient to install due to its hidden installation position; in addition, since the width of the air inlet gradually decreases from front to back, the oil net is installed from the front end of the air inlet with a larger width, and moves along the air inlet from front to back, thereby realizing blind installation and positioning of the oil net.

[0009] As a preferred solution of the installation structure of the oil net, the limiting fold is supported and abutted against the limiting structure.

[0010] As a preferred solution of the installation structure of the oil net, the limiting fold includes a first fold, the first fold is connected to the oil net body, and the first fold is gradually inclined from one end connected to the oil net body to the other end in a direction away from the oil net body;

[0011] The limiting structure includes a first limiting surface, which is connected to the bottom wall of the air inlet. The first limiting surface is gradually inclined from one end connected to the bottom wall of the air inlet to the other end toward a direction away from the air inlet, and the first folded edge can be supported on the first limiting surface.

[0012] The above arrangement of the first folded edge and the first limiting surface can support and limit the first folded edge in the Z direction through the first limiting surface, thereby preventing the oil net body from falling along the Z direction.

[0013] As a preferred solution of the above-mentioned oil screen installation structure, the limiting folding edge also includes:

[0014] a second folded edge, wherein the first folded edge is connected to the oil net body through the second folded edge;

[0015] The limiting structure also includes:

[0016] A second limiting surface, wherein the first limiting surface is connected to the bottom wall of the air inlet through the second limiting surface, and the second folded edge can abut against the second limiting surface.

[0017] The above arrangement can limit the oil screen body in the front-rear direction of the range hood through the abutment cooperation between the second folded edge and the second limiting surface.

[0018] As a preferred solution of the installation structure of the above oil net, the second folded edge is vertically connected to the oil net body, and the second limiting surface is vertically connected to the bottom wall of the air inlet.

[0019] The above arrangement can achieve accurate positioning of the oil screen by abutting and fitting the second folded edge with the second limiting surface.

[0020] As a preferred solution of the installation structure of the oil net, the length of the first folded edge is greater than the length of the first limiting surface.

[0021] The above arrangement can effectively support the first folded edge through the first limiting surface, thereby preventing the oil net from falling.

[0022] As a preferred solution of the installation structure of the oil net, the first folded edge and the plane where the oil net body is located are α, the first limiting surface and the plane where the oil net body is located are β, and α is equal to β.

[0023] The above arrangement enables the first folded edge to fit with the first limiting surface, thereby improving the support stability of the first limiting surface on the first folded edge.

[0024] As a preferred solution for the installation structure of the above-mentioned oil net, the width of the front end of the air inlet is greater than the width of the limiting folded edge and smaller than the width of the oil net body; the width of the limiting folded edge is equal to the size of the rear end of the air inlet.

[0025] The above arrangement can extend into the air inlet through the limiting folded edge and move from front to back along the air inlet, thereby guiding the oil net body so that the oil net body is installed in the installation groove and does not extend into the air inlet.

[0026] The width of the limiting fold is equal to the size of the rear end of the air inlet, and the limiting fold slides along the side wall of the air inlet to the limiting structure, so that the oil net can be automatically aligned with the installation groove during installation, ensuring that the oil net is installed in place, and realizing convenient installation and disassembly of the oil net.

[0027] As a preferred solution for the installation structure of the above-mentioned oil net, a panel is provided at the bottom of the smoke hood, and the panel covers the rear end of the air inlet. The limiting folded edge of the oil net can extend into the air inlet from the front end of the air inlet and move from front to back along the air inlet.

[0028] Since the panel blocks the rear end of the air inlet, the installation position of the oil net is relatively hidden. The limiting folded edge of the oil net can extend from the front end of the air inlet into the air inlet and move from front to back along the air inlet to be installed, thus realizing blind installation of the oil net.

[0029] As a preferred solution of the installation structure of the oil net, a magnetic attraction component is provided at the front end of the installation groove, and the front end of the oil net is magnetically connected to the magnetic attraction component.

[0030] The front end of the oil net is magnetically connected to the magnetic component, allowing users to easily install and replace the oil net without the need for additional tools. This design improves the convenience of operation. Users only need to move the front end of the oil net close to the magnetic component to firmly fix the front end of the oil net without the need for cumbersome screws or snap operations.

[0031] The utility model provides a range hood, comprising a range hood body and a smoke collecting hood arranged on the range hood body, such as the above-mentioned oil net mounting structure, wherein an oil net is mounted on the oil net mounting structure.

[0032] The range hood can realize blind installation and positioning of the oil net through the above-mentioned oil net installation structure.

[0033] Beneficial effects of the utility model:

[0034] The installation structure of the oil net proposed in the utility model gradually reduces the width of the air inlet from front to back and provides a limiting structure at the rear end of the air inlet. The limiting folded edge at the rear end of the oil net body can extend into the air inlet, and the air inlet can guide the limiting folded edge to move from front to back so that the limiting folded edge and the limiting structure are abutted against each other, thereby guiding the oil net to be installed in place, so that the oil net can be installed in the installation groove without additional alignment operation, thereby being suitable for dark environments or situations where the oil net is inconvenient to install due to its hidden installation position; in addition, since the width of the air inlet gradually decreases from front to back, the oil net is installed from the front end of the air inlet with a larger width, and moves along the air inlet from front to back, thereby realizing blind installation and positioning of the oil net.

[0035] The range hood provided by the utility model can realize blind installation and positioning of the oil net through the installation structure of the oil net. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0063] like Figure 1-Figure 6As shown, this embodiment provides a range hood, including a range hood body 100 and a chassis 200, the chassis 200 is arranged above the range hood body 100 and is connected with the range hood body 100, the range hood body 100 includes a smoke collecting hood 10, a smoke collecting chamber 101 is formed inside the smoke collecting hood 10, an air inlet 12 connected with the smoke collecting chamber 101 is opened on the smoke collecting hood 10, an oil net 2 is arranged at the air inlet 12, a fan system is arranged in the chassis 200, and an air outlet 201 is arranged on the top of the chassis 200, through the operation of the fan system, the oil smoke enters the smoke collecting chamber 101 through the oil net 2 at the air inlet 12, and is discharged from the air outlet 201.

[0064] Specifically, the range hood body 100 also includes two left and right side panels 20, and the side panels 20 are respectively arranged on the left and right sides of the smoke hood 10. The front side of the smoke hood 10 is provided with an openable wind deflector 30, the rear side is provided with an oil cup assembly 40, and the bottom is attached with a panel 50, the panel 50 blocks the rear end of the air inlet 12, and the function of the panel 50 is to reduce the area of ​​the air inlet 12, increase the wind pressure, and help to exhaust smoke more quickly. The above components together form a smoke collection structure with a cavity structure inside. The oil net 2 is installed at the air inlet 12. Since the panel 50 blocks the installation position of the oil net 2, the oil net 2 must be blindly installed under obstructed vision, especially in a dark environment or because the installation position of the oil net 2 is hidden due to the obstruction of the smoke collection structure of the range hood, which makes the installation of the oil net 2 more difficult.

[0065] In order to solve the above problems, Figure 6-Figure 10 As shown, this embodiment provides an oil screen installation structure, including an installation groove 11 arranged on the smoke collecting hood 10 of the range hood body 100, the installation groove 11 is located at the upper end of the smoke collecting chamber 101, and the bottom of the installation groove 11 is provided with an air inlet 12 connected to the smoke collecting chamber 101, the width of the air inlet 12 gradually decreases from front to back (the side of the range hood body 100 facing the user is the front, and the side opposite to the front is the rear), and a limiting structure 13 is provided at the rear end of the air inlet 12; the installation groove 11 is provided at the upper end of the smoke collecting chamber 101, and the air inlet 12 is provided at the lower end of the smoke collecting chamber 101. An oil net 2 is installed, and the shape and size of the installation groove 11 are consistent with the shape and size of the oil net 2, and the depth of the installation groove 11 is consistent with the thickness of the oil net 2. When the oil net is installed in place, the surface is flush with the inner surface of the smoke collecting chamber 101, and a limiting folded edge 22 is provided at the rear end of the oil net body 21 of the oil net 2. The limiting folded edge 22 can extend into the air inlet 12, and the air inlet 12 can guide the limiting folded edge 22 to move from front to rear, so that the limiting folded edge 22 abuts against the limiting structure 13 to guide the oil net 2 into place.

[0066] The air inlet 12 can guide the limiting fold 22 to move from front to back so that the limiting fold 22 abuts against the limiting structure 13, thereby guiding the oil net 2 to be installed in place, so that the oil net 2 can be installed in the installation groove 11 without additional alignment operation, so that it can be suitable for dark environments or situations where the installation position of the oil net 2 is hidden and inconvenient to install; in addition, since the width of the air inlet 12 gradually decreases from front to back, the oil net 2 is installed from the front end of the air inlet 12 with a larger width, and moves from front to back along the air inlet 12, thereby realizing blind installation and positioning of the oil net 2.

[0067] In this embodiment, the air inlet 12 is a trapezoidal structure, and the side walls of the air inlet 12 form two trapezoidal bevels 121. The two trapezoidal bevels 121 play a guiding role when the oil net 2 is installed, ensuring that the oil net 2 can automatically return to align with the installation slot 11 and accurately position during the installation process. The width of the front end of the air inlet 12 is greater than the width of the limiting fold 22, and is smaller than the width of the oil net body 21. The above-mentioned setting can extend into the air inlet 12 through the limiting fold 22, and move from front to back along the air inlet 12, which plays a role in guiding the oil net body 21, so that the oil net body 21 is installed in the installation slot 11 and does not extend into the air inlet 12. The width of the limiting fold 22 is equal to the size of the rear end of the air inlet 12. The limiting fold 22 slides along the trapezoidal bevel 121 of the air inlet 12 to the limiting structure 13, so that the oil net 2 can automatically align with the installation groove 11 during installation, ensuring that the oil net 2 is installed in place and preventing the oil net 2 from being in the left and right directions ( Figure 8 The oil screen 2 can be moved in the X direction to realize convenient installation and removal.

[0068] like Fig.10 , Figure 12-16 As shown, the limiting fold 22 includes a first fold 221, which is connected to the oil net body 21, and the first fold 221 gradually tilts from one end connected to the oil net body 21 to the other end in a direction away from the oil net body 21; the limiting structure 13 includes a first limiting surface 131, which is connected to the bottom wall of the air inlet 12, and the first limiting surface 131 gradually tilts from one end connected to the bottom wall of the air inlet 12 to the other end in a direction away from the air inlet 12, and the first fold 221 can be supported by the first limiting surface 131. The first limiting surface 131 supports and limits the first fold 221 in the Z direction, so as to prevent the oil net body 21 from moving along the Z direction ( Fig.10 Z direction) falls.

[0069] Furthermore, the limiting fold 22 further includes a second fold 222, and the first fold 221 is connected to the oil net body 21 through the second fold 222; the limiting structure 13 further includes a second limiting surface 132, and the first limiting surface 131 is connected to the bottom wall of the air inlet 12 through the second limiting surface 132, and the second fold 222 can abut against the second limiting surface 132. Through the abutment and cooperation between the second fold 222 and the second limiting surface 132, the oil net body 21 can be adjusted in the front and rear directions of the range hood ( Fig.10 Limit the position in the Y direction.

[0070] Preferably, the second folded edge 222 is vertically connected to the oil net body 21 ; the second limiting surface 132 is vertically connected to the bottom wall of the air inlet 12 , and the second folded edge 222 and the second limiting surface 132 can abut and fit together to achieve precise positioning of the oil net 2 .

[0071] In this embodiment, the first folded edge 221 forms an acute angle with the plane where the oil net body 21 is located, and the first limiting surface 131 forms an acute angle with the plane where the oil net body 21 is located, so that the first folded edge 221 is better supported on the first limiting surface 131. Preferably, the first folded edge 221 forms an angle α with the plane where the oil net body 21 is located, and the first limiting surface 131 forms an angle β with the plane where the oil net body 21 is located. In this embodiment, the value range of α is 45° to 60°, and the specific α can be 45°, 50°, 60°, etc. The value range of β is 45° to 60°, and the specific β can be 45°, 50°, 60°, etc. The above setting can enable the first limiting surface 131 to support and limit the second limiting surface 132 in the Z direction, so as to prevent the oil net body 21 from falling; and the structure is simple and easy to prepare, and the above value range will not affect the cooperation between the limiting folded edge 22 extending into the air inlet 12 and the limiting structure 13.

[0072] In this embodiment, α and β are equal, so that the first folded edge 221 can fit the first limiting surface 131, thereby improving the support stability of the first limiting surface 131 on the first folded edge 221. The length of the first folded edge 221 is greater than the length of the first limiting surface 131, thereby increasing the contact area between the two, improving the support effect of the first limiting surface 131 on the first folded edge 221, and preventing the oil net 2 from falling.

[0073] Preferably, the two side walls of the first fold edge 221 gradually narrow from one end connected to the second fold edge 222 to the other end. In this embodiment, the first fold edge 221 is also a trapezoidal structure, and the two side walls of the first fold edge 221 can cooperate with the side wall guide of the air inlet 12.

[0074] The existing oil screen is generally fixed and installed by screws or buckles. This traditional installation method has the problem of low efficiency. In order to achieve the rapid installation of the front end of the oil screen 2, such as Figure 8 , Fig. 9 and Fig.11 As shown, a magnetic component 14 is provided at the front end of the mounting slot 11, and the front end of the oil net 2 is magnetically connected to the magnetic component 14. The front end of the oil net 2 is magnetically connected to the magnetic component 14, so that the user can easily complete the installation and replacement of the oil net 2 without additional tools. This design improves the convenience of operation. The user only needs to bring the front end of the oil net 2 close to the magnetic component 14 to achieve a firm fixation of the front end of the oil net 2 without complicated screw or buckle operations.

[0075] Specifically, the magnetic suction component 14 includes a magnetic suction component 141 and a cover 142. The cover 142 is installed on the mounting platform of the smoke hood 10, and the magnetic suction component 141 is arranged inside the cover 142. In this embodiment, the cover 142 is fixed by screws. In other embodiments, the connection method between the cover 142 and the mounting platform can also be other methods, as long as the cover 142 can be connected to the mounting platform.

[0076] like Fig.12 and Fig.13 As shown, the oil net 2 is provided with a disassembly hole 211. In this embodiment, two disassembly holes 211 are provided on the oil net 2. The disassembly holes 211 provide the user with a gripping point of the oil net 2. The user can pass through the disassembly holes 211 with a finger to facilitate the disassembly and assembly of the oil net 2. The shape of the disassembly hole 211 is similar to the hole shape of the oil net 2 or the spliced ​​shape of the holes, so that the appearance of the oil net 2 is unified and beautiful, and the oil net 2 is convenient to be taken out of the installation slot 11. In other embodiments, the number of disassembly holes 211 is not limited to two, and can also be one, three, four or more, which can be set according to needs.

[0077] Continue to see Fig.12 and Fig.13 , an indicator mark 212 is provided at the front end of the front face of the oil net 2. The indicator mark 212 provided at the front end of the front face of the oil net 2 can prevent the user from being unable to distinguish the front and rear ends and the front and back sides of the oil net 2 when installing the oil net 2. The design of the indicator mark 212 can help the user to quickly install the oil net 2. In this embodiment, the indicator mark 212 is in the shape of an arrow, which can serve as a guide for installation. The indicator mark 212 is located in the middle of the front end of the front face of the oil net 2, and the two disassembly holes 211 are located on both sides of the indicator mark 212.

[0078] When installing the oil screen 2, Figure 5 , Figure 8As shown, first, the limiting folded edge 22 is facing upwards, and the arrow in the indicator mark 212 is aligned with the user, and the oil net 2 is placed parallel to the air inlet 12 along the direction A. Since the width of the oil net 2 is greater than the trapezoidal width of the air inlet 12, and the width of the limiting folded edge 22 is less than the width of the front end of the air inlet 12, the limiting folded edge 22 of the oil net 2 will slide along the trapezoidal oblique edge 121 of the air inlet 12 to the bottom of the installation slot 11, and the trapezoidal oblique edge 121 of the air inlet 12 will The first folded edge 221 acting as the guide edge and the limiting folded edge 22 cooperates. Since the width of the limiting folded edge 22 is equal to the width of the rear end of the air inlet 12, the freedom of the oil net 2 in the X direction is limited. When the oil net 2 is pushed to the bottom of the installation groove 11 along the trapezoidal oblique edge 121 and contacts the inner surface of the installation groove 11, the second folded edge 222 of the limiting folded edge 22 cooperates with the second limiting surface 132 of the limiting structure 13, thereby limiting the freedom of the oil net 2 in the Y direction. Figure 5 and Fig. 9 As shown, at this time, the user flips the oil net 2 along the B direction until the oil net 2 falls into the installation groove 11, and the front end of the oil net 2 is adsorbed and fixed by the magnetic suction component 14. At this time, the first folded edge 221 of the limiting folded edge 22 and the first limiting surface 131 of the limiting structure 13 form an inclined plane to limit the freedom of the oil net 2 in the Z direction.

[0079] It should be noted that: since the rear end of the air inlet 12 is blocked by the panel 50, when the oil screen 2 is installed, the limiting folded edge 22 extends from the front end of the air inlet 12 into the air inlet 12 and moves from front to back along the air inlet 12 to achieve blind installation and positioning of the oil screen.

[0080] The range hood solves the problem of obstructed vision that a user may face when installing the oil net 2, especially in a dark environment or when the installation position of the oil net 2 is concealed due to the obstruction of the smoke collecting structure of the range hood.

[0081] It should be noted that the installation structure of the oil net is not limited to range hoods, but can also be applied to integrated stoves, etc., to solve the technical problem that it is difficult for users to correctly perform the operations of aligning and installing the oil net in dark environments or because the installation location is relatively hidden due to the gathering structure of the integrated stove.

[0082] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
