[0032] The utility model provides a range hood 100 .

[0033] See also Figures 1 to 6 In one embodiment of the present invention, the range hood 100 comprises:

[0034] The housing 1 is provided with an oil fume suction passage 11; and

[0035] The diversion structure 2 is arranged in the oil fume suction channel 11 and is used to divide the oil fume suction channel 11 into a left channel 111 and a right channel 112 . The housing 1 is provided with an inwardly protruding mounting boss 12 , and the diversion structure 2 is mounted on the mounting boss 12 .

[0036] Specifically, the range hood 100 mainly includes a fume hood, a chassis, a filter, a fume suction channel 11, a fan system and other components. The fan system is arranged in the chassis. When the range hood 100 is working, the fan rotates at a high speed inside the range hood 100, so that there is a certain pressure difference inside and outside the range hood 100, so that the air outside the range hood 100 flows into the range hood 100 through the fume suction channel 11, and the fume generated when cooking food is discharged. Therefore, the smoke hood is provided with an air inlet, and a smoke suction channel 11 is provided in the shell 1 of the range hood 100. The air inlet end of the smoke suction channel 11 is connected to the air inlet, and the air outlet end is connected to the fan system. In order to adapt to the layout of the left and right double stoves in the kitchen, the range hood 100 is usually configured as a double-duct range hood 100, that is, two air inlets are provided on the air guide plate of the smoke hood, temporarily set as the left air inlet and the right air inlet. The diversion structure 2 is usually arranged on the inner side of the air guide plate and between the left air inlet and the right air inlet. The diversion structure 2 divides the smoke suction channel 11 into a left channel 111 and a right channel 112, so the diversion structure 2 is usually arranged below the fan system.

[0037] In the prior art, the flow-dividing structure 2 is generally directly mounted on the housing 1 through fasteners, so a through hole is provided on the housing 1, and the fastener passes through the through hole and is fastened to the flow-dividing structure 2. When the range hood 100 is working, oil droplets will flow down along the outer shell 1 from the fan system, causing the oil droplets to seep out from the through holes, which is not only difficult to clean but also may contaminate the wall. Therefore, a mounting boss 12 is convexly provided inside the outer shell 1, that is, the height of the mounting boss 12 is greater than the height of the periphery of the mounting boss 12, that is, the mounting boss 12 and its periphery are not on the same plane, and the diverter structure 2 is installed on the mounting boss 12, that is, the diverter structure 2 is provided on the plane where the mounting boss 12 is parallel to the outer shell 1, which also makes the mounting plane of the diverter structure 2 and the mounting boss 12 not on the same plane as the plane where the oil droplets flow down, so that when the oil droplets flow down along the outer shell 1 from the fan system to the mounting boss 12, they will flow downward along the edge of the mounting boss 12, and will not flow to the plane where the mounting boss 12 is parallel to the outer shell 1, thereby reducing the possibility of oil droplets flowing to the mounting boss 12 and the installation place of the diverter structure 2, thereby reducing the possibility of accidental leakage of oil droplets and reducing the difficulty of cleaning.

[0038] At this time, the diverter structure 2 can be installed on the shell 1 in a detachable manner, such as the diverter structure 2 is installed on the shell 1 by snap-fitting or fastener connection, or it can be installed on the shell 1 in a non-detachable manner, such as the diverter structure 2 is installed on the shell 1 by bonding or welding.

[0039] In the embodiment of the utility model, the diverter structure 2 can be detachably mounted on the mounting boss 12. Specifically, the diverter structure 2 can be detachably mounted on the mounting boss 12, which can facilitate the user to clean the interior of the range hood 100 and facilitate subsequent maintenance. Among them, detachable means that when cleaning and subsequent maintenance are required, the structure of the range hood 100 itself will not be damaged, including disassembly without the help of any tools, and installation without the help of any tools, so as to facilitate the user to disassemble and clean, and keep the range hood 100 hygienic; it also includes disassembly that can be easily disassembled and assembled using common tools without the need for professional tools or professional guidance.

[0040] Furthermore, in order to facilitate the installation of the diverter structure 2, a pre-installation structure and a fixed structure are provided between the mounting boss 12 and the diverter structure 2. Specifically, the pre-installation structure is used to perform preliminary positioning and installation of the mounting boss 12 and the diverter structure 2, and then the diverter structure 2 is further installed on the mounting boss 12 through the fixed structure, so as to facilitate preliminary positioning of the diverter structure 2 and ensure the accuracy of the installation position. The pre-installation structure preliminarily fixes the diverter structure 2, and there is no need to use manpower or tools to position the diverter structure 2 during the fixing process of the fixed structure. In other embodiments, only a fixed structure may be provided between the mounting boss 12 and the diverter structure 2.

[0041] See also Figures 3 to 6 In the embodiment of the utility model, the pre-installation structure includes a hook 21 provided on the diverter structure 2 and a hole 121 provided on the mounting boss 12. The hook 21 passes through the hole 121 and is engaged with the edge of the hole 121. Specifically, the diverter structure 2 has a hook 21, and the mounting boss 12 is provided with a hole 121. The hook 21 passes through the hole 121 and is engaged with the edge of the hole 121, thereby realizing the preliminary positioning and installation of the diverter structure 2. The coordination of the hook 21 and the hole 121 can facilitate the installation of the diverter structure 2 and the mounting boss 12, thereby facilitating the assembly of the operator.

[0042] Among them, the hook 21 can be integrally formed with the diverter structure 2, thereby ensuring the installation stability of the diverter structure 2 and reducing the assembly process of the hook 21 and the diverter structure 2. Of course, in other embodiments, the hook 21 can also be bonded or clamped to the diverter structure 2.

[0043] In the embodiment of the present invention, the hook 21 is engaged with the upper edge of the hole 121, and the lower edge of the hole 121 is in contact with the lower side of the hook 21 to prevent the hook 21 from slipping out of the hole 121. Specifically, the hook 21 is engaged with the upper edge of the hole 121, that is, the flow-dividing structure 2 is assembled to the mounting boss 12 from bottom to top. Compared with the hook 21 being engaged with the lower edge of the hole 121, since the fan system is disposed above the mounting boss 12, the flow-dividing structure 2 is assembled from top to bottom, and the flow-dividing structure 2 may interfere with the fan system, which is not conducive to the installation and removal of the flow-dividing structure 2. When the hook 21 is engaged with the upper edge of the hole 121, in order to reduce the possibility that the hook 21 escapes from the hole 121 and causes the diverter structure 2 to fall accidentally, the lower edge of the hole 121 abuts against the lower side of the hook 21, thereby preventing the hook 21 from escaping from the hole 121 and ensuring the installation stability of the diverter structure 2. In other embodiments, the hook 21 is engaged with the upper edge, left edge, or right edge of the hole 121.

[0044] To further facilitate the installation of the diversion structure 2, in the embodiment of the present utility model, please refer to Figure 4 and Figure 6, a guide avoidance groove 122 connected to the clamping hole 121 is provided at the lower side of the clamping hole 121, and the guide avoidance groove 122 extends downward to guide the clamping hook 21. Specifically, the guide avoidance groove 122 extends downward, that is, the guide avoidance groove 122 extends along the installation direction of the diverter structure 2, so that during the installation process, the clamping hook 21 partially extends into the guide avoidance groove 122 and slides into the clamping hole 121 along the extension direction of the guide avoidance groove 122, thereby facilitating the installation of the diverter structure 2. And at this time, in order to ensure that the clamping hook 21 can not be separated from the clamping hole 121, the depth of the guide avoidance groove 122 is less than the thickness of the clamping portion of the upper edge of the clamping hook 21 and the clamping hole 121, so that the side of the guide avoidance groove 122 facing the clamping hole 121 abuts against the lower side of the clamping hook 21.

[0045] Please refer again Figures 3 to 6 In an embodiment of the utility model, the fixing structure includes a first mounting hole 22 provided on the diverter structure 2, and a second mounting hole 123 provided on the mounting boss 12, and the fastener passes through the first mounting hole 22 and is connected to the second mounting hole 123. Specifically, the diverter structure 2 is fixed to the mounting boss 12 by the fastener, so that the installation of the diverter structure 2 is convenient and the fixing stability of the diverter structure 2 is ensured. The diverter structure 2 is provided with a first mounting hole 22, and the mounting boss 12 is provided with a second mounting hole 123, and the fastener passes through the first mounting hole 22 and is connected to the second mounting hole 123, that is, the fastener is installed from one side of the diverter structure 2, that is, installed from the oil fume suction channel 11. Compared with the fastener installed from one side of the back side of the shell 1, when installing the diverter structure 2, this solution does not need to flip the range hood 100, thereby facilitating the installation of the diverter structure 2.

[0046] Among them, in this scheme, the preliminary positioning and installation are achieved by the cooperation of the hook 21 and the hole 121, and then the fastener is matched to further ensure the fixing stability of the diverter structure 2. In other embodiments, the pre-installation structure includes a snap-on structure, and the installation structure includes a first installation hole 22 provided on the diverter structure 2 and a second installation hole 123 provided on the mounting boss 12, and the fastener passes through the first installation hole 22 and is connected to the second installation hole 123. Alternatively, the pre-installation structure includes a hook 21 provided on the diverter structure 2 and a hole 121 provided on the mounting boss 12, the hook 21 passes through the hole 121 and is snap-on to the edge of the hole 121, and the installation structure is configured as a snap-on structure. Alternatively, the pre-installation structure is configured as an adhesive such as a tape, and the diverter structure 2 is initially positioned and installed on the mounting boss 12 by the adhesive, and then fixedly installed by the fastener, and the tape is torn off after the fastener is fixedly installed. The fastener can be configured as a fastening screw or a fastening bolt, and the fastener is connected to the second mounting hole 123 by a thread.

[0047] To facilitate the installation of fasteners, in the embodiments of the present invention, please refer to Figure 1 to Figure 2 The edge of the diverter structure 2 is provided with a mounting foot 23, and the first mounting hole 22 passes through the mounting foot 23. Specifically, the mounting foot 23 protrudes from the edge of the diverter structure 2, and the thickness of the mounting foot 23 is less than or equal to the thickness of the diverter structure 2, so that the first mounting hole 22 is conveniently set.

[0048] Among them, the mounting foot 23 can be integrally formed with the diverter structure 2, thereby ensuring the installation stability of the diverter structure 2 and reducing the assembly process of the mounting foot 23 and the diverter structure 2. Of course, in other embodiments, the mounting foot 23 can also be bonded or clamped to the diverter structure 2.

[0049] In the embodiment of the utility model, the shell 1 is partially raised inward to form the mounting boss 12, and the mounting boss 12 is partially raised toward the outside of the shell 1 to form the guide avoidance groove 122. Specifically, the shell 1 is partially raised inward to form the mounting boss 12, that is, the mounting boss 12 is partially formed by stamping the shell 1, and an avoidance groove 124 is formed on the back of the mounting boss 12, so that the hook 21 passes through the clamping hole 121 and extends into the avoidance groove 124, thereby reducing the possibility of the hook 21 protruding from the outside of the shell 1, ensuring the installation stability of the range hood 100, and facilitating the processing of the clamping hole 121. The mounting boss 12 is partially raised toward the outside of the shell 1 to form the guide avoidance groove 122, that is, the guide avoidance groove 122 is partially formed by stamping the mounting boss 12, thereby facilitating the processing of the guide avoidance groove 122.

[0050] Furthermore, the inner edge of the second mounting hole 123 is provided with a mounting flange 125 extending into the avoidance groove 124. When the mounting boss 12 is formed by partial stamping of the housing 1, the thickness of the mounting boss 12 is relatively thin, and the depth of the second mounting hole 123 is relatively small, so it is difficult to ensure the mounting strength of the mounting boss 12 and the fastener. For example, when the fastener is connected to the second mounting hole 123 by threading, it is easy to slip. Therefore, the inner edge of the second mounting hole 123 is provided with a mounting flange 125 extending into the avoidance groove 124, thereby increasing the depth of the second mounting hole 123, increasing the contact area between the second mounting hole 123 and the mounting boss 12, and ensuring the mounting strength of the mounting boss 12 and the fastener. However, in order to ensure the smoothness of the installation of the range hood 100, the mounting flange 125 is located in the avoidance groove 124.

[0051] In the embodiment of the present invention, the diversion structure 2 includes a fixed portion and a rotating portion rotatably connected to the fixed portion. The fixed portion is mounted on the mounting boss 12 , and the rotating portion can adjust the size of the left channel 111 and the right channel 112 . The fixed part and the rotating part together separate the oil fume suction channel 11 into a left channel 111 and a right channel 112. In some cases, the user may only work with a single stove. At this time, only the left air inlet or the right air inlet needs to be opened. At this time, if the flow areas of the left channel 111 and the right channel 112 are the same, it will inevitably cause a waste of energy and wind power. Therefore, the rotating part can rotate relative to the fixed part to adjust the size of the left channel 111 and the right channel 112. When only the left air inlet needs to be opened, the rotating part rotates to the right, thereby increasing the flow area of ​​the left channel 111 and reducing the flow area of ​​the side air duct, thereby improving the oil fume suction rate; when only the right air inlet needs to be opened, the rotating part rotates to the left, thereby increasing the flow area of ​​the right channel 112 and reducing the flow area of ​​the left air duct, thereby improving the oil fume suction rate. The fixed part is installed on the mounting boss 12, so as to ensure the stable installation of the diversion structure 2 without affecting the rotation of the rotating part.

[0052] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
