DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0031] like Figure 1 and Figure 2 As shown, the range hood includes an independently arranged main unit 1 and a smoke inlet assembly 2, and the smoke inlet assembly 2 is installed below the main unit 1. The main unit 1 is provided with an upper flue 11 and a fan module 13 located in the upper flue 11. The fan module 13 usually adopts a centrifugal fan, and when the fan module 13 is working, a negative pressure is generated in the upper flue 11 to suck the oil fume and perform oil fume separation treatment on the oil fume. A lower flue 21 is arranged in the smoke inlet assembly 2, and a smoking port of the lower flue 21 is provided at the lower end of the smoke inlet assembly 2, so that the smoke inlet assembly 2 is closer to the stove of industrial oil fume, and the oil fume is better sucked into the lower flue 21. After the smoke inlet assembly 2 is installed below the main unit 1, the lower flue 21 is connected to the upper flue 11.

[0032] By adopting independent split structures for the main unit 1 and the smoke inlet assembly 2, the main unit 1 and the smoke inlet assembly 2 can be manufactured, packaged and transported separately, thereby facilitating the production, manufacturing and transportation of the manufacturer.

[0033] A smoke exhaust interface 12 is provided at the top of the main unit 1, and the lower end of the smoke exhaust interface 12 is connected to the upper flue 11. When in use, the smoke exhaust interface 12 is connected to the smoke exhaust pipe of the installation environment, and the smoke after the smoke oil separation treatment is sent from the smoke exhaust interface 12 to the smoke exhaust pipe for discharge.

[0034] The present application mainly improves the split installation structure of the smoke oil machine, so that the smoke inlet component 2 can be installed under the main unit 1 more simply and conveniently, simplifying the installation operation to facilitate installation and subsequent disassembly and maintenance.

[0035] Further integration Figure 2-Figure 6 The split installation structure includes: a hanging rod 14 is horizontally arranged at the lower end of the main unit 1, and a hanging slot 141 is arranged on the hanging rod 14. Figure 1 and Figure 4 shown; see especially Figure 1 and Figure 5As shown, a hanging member 22 is longitudinally arranged at the upper end of the smoke inlet assembly 2, and a hook 221 is arranged at the upper end of the hanging member 22, and the hook 221 is hung and connected with the hanging slot 141 so that the smoke inlet assembly 2 is hung at the lower end of the host 1, so that the weight of the smoke inlet assembly 2 is supported on the hanging rod 14 through the hook 221, thereby avoiding the need for the installer to lift the smoke inlet assembly 2 with force during the installation process, thereby simplifying the installation operation; a locking assembly is arranged between the host 1 and the smoke inlet assembly 2, and the locking assembly limits the rotation of the hook 221 relative to the hanging slot 141 so that the lower flue 21 and the upper flue 11 are kept in communication, as shown in FIG. Figure 1 and Figure 2 described.

[0036] By configuring a horizontal hanging rod 14 at the lower end of the main unit 1 and a longitudinally arranged hook 221 at the upper end of the smoke inlet assembly 2, and using the hook 221 to hang on the hanging rod 14, the smoke inlet assembly can be quickly assembled and positioned with the main unit during assembly, and the overall weight of the smoke inlet assembly can be supported on the main unit through the hook, without the user having to perform cumbersome assembly alignment and lift the smoke inlet assembly with force during assembly.

[0037] After the smoke inlet assembly is installed in place relative to the main unit, that is, the lower flue 21 is in sealed communication with the upper flue 11, the main unit 1 and the smoke inlet assembly 2 are locked by a locking assembly, and the smoke inlet assembly 2 is installed below the main unit 1. The entire installation operation is simple, and the installation is convenient and quick.

[0038] Especially combined with Figure 4 As shown, the lower end surface of the main unit 1 is provided with a lower port 111 of the upper flue 11, and the hanging rod 14 is hidden in the lower port 111; Figure 5 As shown, the upper end surface of the smoke inlet assembly 2 is provided with an upper port 211 of the lower smoke duct 21 , the hanging member 22 is fixed in the upper port 211 , and the hook 221 extends out of the upper port 211 .

[0039] When the smoke inlet assembly 2 is installed below the main unit 1, the hook 221 is extended from the lower port 111 into the upper flue 11 of the main unit 1 and is hung on the hanging rod 14. This structure can reduce the distance between the upper end surface of the smoke inlet assembly 2 and the lower end surface of the main unit 1, ensuring that the lower flue 21 and the upper flue 11 form a sealed communication structure during installation.

[0040] In order to make the matching structure between the hook 221 and the hanging rod 14 more reliable, two hanging slots 141 are provided on the hanging rod 14. Correspondingly, there are also two hanging parts 22. A hook 221 is provided at the end of each hanging part 22, and each hook 221 is respectively matched with a hanging slot 141 for hanging.

[0041] Furthermore, the two hanging slots 141 are respectively located on the two opposite sides of the lower port 111 on the hanging rod 14, and the two hooks 221 are respectively located on the two opposite ends of the upper port 211. Such a structure makes it easier to position and hang the hook 221 during installation, so that the hook 221 can be quickly hung in the hanging slot 141 by extending from the lower port 111 into the upper flue 11 of the main unit 1.

[0042] In addition, the hanging rod 14 is arranged obliquely above the lower port 111 so that the orthographic projection of the hanging rod 14 is not located at the lower port 111. The advantage of such arrangement is that the hanging rod 14 will not block the lower port 111 and reduce the efficiency of oil fume absorption.

[0043] Furthermore, there is a gap between the hanging rod 14 and the lower end surface of the main machine 1 to provide the hook 221 with the required rotation, so as to facilitate the hook 221 to be hung in the hanging slot 141 of the hanging rod 14 .

[0044] Especially combined with Figure 6 As shown, the opening of the hook 221 is set downward, and the inner walls on both sides of the opening are set as guide arc surfaces 2211. The guide arc surfaces 2211 and the outer side surfaces of the hanging rod 14 are used for guidance, which is conducive to quickly positioning the hook 221 to the hanging slot 141 to achieve positioning and hanging.

[0045] There are many ways to implement the locking assembly. The main function of the locking assembly is to lock the smoke inlet assembly 2 with the main unit 1 after the smoke inlet assembly 2 is accurately installed under the main unit 1, so that the lower flue 21 and the upper flue 11 are kept in a sealed communication arrangement.

[0046] In one embodiment, the locking assembly includes: a first magnetic portion 15 arranged on the lower end surface of the main unit 1, and a second magnetic portion 23 arranged on the upper end surface of the smoke inlet assembly 2, the first magnetic portion 15 and the second magnetic portion 23 are magnetically attracted and connected to lock the smoke inlet assembly 2 and the main unit 1.

[0047] The first magnetic part 15 is a permanent magnetic block or a magnetic connector, and correspondingly, the second magnetic part 23 is also a permanent magnetic block or a magnetic connector.

[0048] In another embodiment, the locking assembly includes a first assembly portion disposed at the lower end of the main unit 1 and a second assembly portion disposed at the upper end of the smoke inlet assembly 2, and the first assembly portion and the second assembly portion are detachably fixedly connected. For example, the first assembly portion and the second assembly portion are both locking plates with screw holes, and the two locking plates are locked together by screws to lock the smoke inlet assembly 2 and the main unit 1.

[0049] In another embodiment, the locking assembly includes a flexible shaft assembly 16 arranged at the lower end of the main unit 1 and a locking hole 24 arranged on the upper end surface of the smoke inlet assembly 2, and the locking stud 161 at the lower end of the flexible shaft assembly 16 extends downward from the lower end surface of the main unit 1, and when the smoke inlet assembly 2 is assembled under the main unit 1, the locking stud 161 is screwed and locked with the locking hole 24.

[0050] Among them, a locking nut 162 for driving the flexible shaft assembly to rotate is provided at the upper end of the flexible shaft assembly 16. The locking nut 162 is exposed on the side panel of the outer shell of the main unit 1 or hidden inside the outer shell of the main unit 1, so as to facilitate the installation operator to drive the flexible shaft assembly 16 to rotate by rotating the locking nut 162, thereby allowing the locking stud 161 to be screwed and locked with the locking hole 24 of the air inlet assembly 2.

[0051] Among them, a flexible shaft assembly 16 is respectively provided on the two end sides of the lower port 111 of the upper flue 11; a locking hole 24 is also respectively provided on the two end sides of the upper port 211 of the lower flue 21, and each locking stud 161 of the flexible shaft assembly 16 is screwed into the locking hole 24 at the corresponding position, so that the air inlet assembly 2 and the main unit 1 have a structurally reliable locking relationship through multi-position locking.

[0052] The working principle of the range hood is as follows: the main unit 1 is fixed to the wall above the stove, and the air inlet assembly 2 is assembled under the main unit 1 using a split mounting structure, so that the suction port at the lower end of the air inlet assembly 2 is close to the stove to absorb the oil fume generated by the stove during cooking; the fan module 13 in the main unit 1 generates a negative pressure in the upper flue 11, so that the oil fume generated by the stove is sucked into the lower flue 21 from the suction port of the air inlet assembly 2 and enters the upper flue 11. The fan module 1 separates the oil fume during the flow of the oil fume through the fan module 1, and finally the smoke is discharged from the exhaust interface into the exhaust duct.

[0053] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
