DETAILED DESCRIPTION

[0026] To further illustrate the technical means and effects taken by the present application to achieve the predetermined purposes, the specific embodiments, structures, features and effects thereof according to the present application are described in detail below in combination with the drawings and preferred embodiments. In the following description, different "an embodiment" or "embodiments" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0027] In combination with Figures 1-4As shown, this utility model discloses a range hood, including a smoke collection hood 2 and a main unit 1 with a turbine fan 12. A separate assembly is provided between the main unit 1 and the smoke collection hood 2. When the range hood is installed and in use, the smoke collection hood 2 is fixedly connected to the bottom of the main unit 1 through the separate assembly. When the range hood is packaged, the smoke collection hood 2 is separately set relative to the main unit 1 through the separate assembly, and the main unit 1 is laid horizontally on the back side of the smoke collection hood 2, so that the smoke collection hood 2 and the main unit 1 are integrated and fixed in the packaging box.

[0028] This utility model provides a separate assembly component between the main unit 1 and the smoke collection hood 2, allowing the range hood to be assembled as a whole in the installation and use state using the separate assembly component, and also allowing the main unit 1 and the smoke collection hood 2 to be separated for convenient packaging.

[0029] By placing the main unit 1 horizontally on the back of the smoke collection hood 2 in the packaged state, the size of the range hood is greatly reduced compared to the size of the range hood in the installed and used state. This allows the range hood to be packaged in a smaller box, making it easy to transport and preventing situations such as the main unit 1 and the smoke collection hood 2 being missing or incompatible during the final sale.

[0030] Meanwhile, since the main unit 1 and the smoke collection hood 2 are in a separate state when packaged, it can avoid damage to the separate assembly components when the main unit 1 moves relative to the smoke collection hood 2 due to external force collisions or other factors during transportation. Therefore, packaging and transporting the range hood in a separate state is beneficial to protecting the range hood.

[0031] For example, the packaging box includes a packaging frame 9 with multiple support parts 93 on its periphery and a packaging cover 8 that can be fixed on the packaging frame 9. A first fixing position 91 and a second fixing position 92 are arranged side by side in the packaging frame 9. The main unit 1 is horizontally placed in the first fixing position 91, and the smoke hood 2 is placed in the second fixing position 92. Then, the main unit 1 and the smoke hood 2 are limited and fixed from the top by the packaging cover 8, thus realizing the integrated packaging of the smoke hood 2 and the main unit 1 in a separate state.

[0032] The encapsulation cover 8 has a limiting part 81 located on the front side of the smoke collection hood 2, so as to provide limiting protection for the smoke collection hood 2 from the front side, making the smoke collection hood 2 more securely fixed in the packaging box, and preventing it from shaking or shifting during transportation, thus protecting the range hood.

[0033] A first receiving groove 82 is provided on the packaging cover plate 8. The oil cup 29, which is detachably mounted on the smoke collection hood 2, is set in the first receiving groove 82 in the packaged state to prevent the oil cup 29 from falling off the smoke collection hood 2 and causing damage during transportation.

[0034] The range hood also includes accessories, which typically include an exhaust pipe 41 connected to the exhaust port of the turbine fan 12 of the main unit 1 and an air outlet 42 connected to the exhaust pipe 41. The air outlet 42 is connected to the flue gas pipeline laid in the installation environment of the range hood, so that the gas discharged by the range hood in the installation and use state is discharged from the flue gas pipeline after passing through the exhaust pipe 41 and the air outlet 42.

[0035] A second receiving groove 83 is provided within the limiting portion 81 of the encapsulation cover 8, and the accessories of the range hood are limited within the second receiving groove 83. By placing the second receiving groove 83 within the limiting portion 81, the accessories of the range hood are confined within the space in front of the smoke collection hood 2 by the limiting portion 81, thereby improving the integration efficiency when the range hood is packaged as a single unit in a single packaging box, which is beneficial for further reducing the packaging volume and lowering packaging and transportation costs.

[0036] In addition, this utility model sets a separate assembly component between the main unit 1 and the smoke collection hood 2, so that the main unit 1 and the smoke collection hood 2 adopt a separate structure design. This is beneficial for manufacturers to use the same main unit 1 to quickly combine and design multiple range hood products with different shapes or functions when developing and designing range hood products, which helps to save development costs.

[0037] Further integration Figures 3-9 As shown, in some preferred embodiments, the split assembly specifically includes: a first latch 141 disposed on two opposite sides of the bottom of the main unit 1, with the opening of the first latch 141 facing a first direction; and a second latch 24 disposed on the top of the smoke hood 2, with the opening of the second latch 24 facing downwards in a second direction; the first direction and the second direction are arranged opposite to each other, so that the first latch 141 is at least partially inserted into the second latch 24 to fix the smoke hood 2 to the bottom of the main unit 1.

[0038] The second direction is from the front of the fume hood 2 towards the back of the fume hood 2. When installing the range hood, first fix the main unit 1 to the wall, then align the second latch 24 on the top of the fume hood 2 with the first latch 141 on the bottom of the main unit 1, and push the fume hood 2 towards the wall in the second direction so that the first latch 141 is at least partially inserted into the second latch 24. By using the insertion of the first latch 141 into the second latch 24, the fume hood 2 is connected to the bottom of the main unit 1.

[0039] The separate assembly also includes: buckle holes 142 on two opposite sides of the bottom of the main unit 1, and locking pieces 25 on the top of the smoke hood 2. During the process of the first buckle 141 being inserted into the second buckle 24, the locking pieces 25 are inserted into the buckle holes 142 to achieve fastening, further improving the connection reliability of the smoke hood 2 to the bottom of the main unit 1.

[0040] To facilitate processing and manufacturing, the bottom of the main unit 1 is provided with a detachable and fixed assembly base frame 14, wherein the first latch 141 and the latch hole 142 are respectively provided on the assembly base frame 14.

[0041] Furthermore, in order to improve the connection between the main unit 1 and the smoke hood 2 in the installation and use state, in some embodiments, an installation groove 23 is provided on the top of the smoke hood 2, and the second latch 24 and the locking piece 25 are both provided on the groove wall of the installation groove 23. In the installation and use state, the bottom of the main unit 1 is inserted into the installation groove 23.

[0042] The main unit 1 includes a housing 10 and a main unit panel 13 installed on one side of the housing 10, with the turbine fan 12 disposed inside the housing. Alternatively, an oil separator 11 is also provided inside the housing 10, with the turbine fan 12 located between the oil separator 11 and the main unit panel 13, so that the turbine fan 12 can be easily cleaned and maintained by removing the main unit panel 13.

[0043] Meanwhile, the oil separator 11 divides the interior of the main unit 1 into two chambers: one chamber is used to connect with the fume hood 2 to provide oily fumes to enter the turbine fan 12; the other chamber is used to install the turbine fan 12 and to isolate the oily fumes in the chamber where the turbine fan 12 is located through the oil separator 11.

[0044] A condenser plate 21 is provided on the front side of the smoke hood 2 and is connected by a hook 22.

[0045] Furthermore, to ensure electrical connection between the main unit 1 and the smoke collection hood 2 during installation and use, in some embodiments, a first electrical interface 15 is provided at the bottom of the main unit 1, and a corresponding second electrical interface 28 is provided at the top of the smoke collection hood 2. When the smoke collection hood 2 is mounted below the main unit 1, the second electrical interface 28 is connected to the first electrical interface 15. Therefore, after the external power supply is routed to the main unit 1, the electrical signal can be routed to the smoke collection hood 2 by connecting the second electrical interface 28 to the first electrical interface 15. This facilitates the arrangement of electrical components such as light panels and sensors within the smoke collection hood 2 without the need for separate wiring.

[0046] In some embodiments, the first electrical interface 15 and the second electrical interface 28 are both magnetic connectors. The first electrical interface 15 is fixed to the bottom of the main unit 1 by a spring 16. When the smoke hood 2 is assembled under the main unit 1, the second electrical interface 28 and the first electrical interface 15 automatically engage with each other using magnetic following. The elastic force generated by the spring 16 ensures that the engagement between the second electrical interface 28 and the first electrical interface 15 is more reliable and less likely to fall off.

[0047] Of course, the first electrical interface 15 and the second electrical interface 28 can also use non-magnetic cable connectors, such as M12 cable connectors. After the smoke hood 2 is assembled under the main unit 1, the first electrical interface 15 and the second electrical interface 28 are manually plugged in and connected. Under the action of the spring 16, it can be ensured that the second electrical interface 28 and the first electrical interface 15 maintain a reliable electrical connection.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
