DETAILED DESCRIPTION

[0031] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0032] Example 1

[0033] refer to Figure 1-4 The present embodiment provides a range hood, comprising a smoke hood 1, an oil cup 22 and a box assembly 7. The smoke hood 1 has an air inlet 111 opening forward, a top air outlet 112 opening upward and a mounting port opening forward (not shown in the figure), the mounting port being located below the air inlet 111 and arranged close to the air inlet 111. A accommodating cavity 13 connected to the mounting port is formed in the smoke hood 1, and an oil leakage hole 512 for connecting to the oil cup 22 is provided at the top of the accommodating cavity 13. The oil cup 22 can movably pass through the mounting port and can be detachably installed in the accommodating cavity 13, for receiving the fluid flowing down from the oil leakage hole 512, the fluid including oil or cleaning water. The box assembly 7 is fixedly mounted on the top of the smoke hood 1 and connected to the top air outlet 112.

[0034] The concealment methods of the oil cup 22 and the mounting opening include but are not limited to any of the following:

[0035] The first type, the range hood also includes a flap assembly 3 and a decorative panel 4, refer to Figure 1-4The decorative panel 4 can be detachably mounted on the smoke hood 1 and is used to open or close the mounting port, so as to hide the hidden oil cup 22 behind the decorative panel 4, thus satisfying the aesthetic requirements of the appearance. The flap assembly 3 can be movably connected to the smoke hood 1, so as to open or close the air inlet 111 and the decorative panel 4, so as to hide the decorative panel 4 behind the flap assembly 3. It can be seen that by placing the oil cup 22 in the smoke hood 1, and first covering the mounting port and the oil cup 22 with the decorative panel 4, and then opening or closing the decorative panel 4 and the air inlet 111 with the flap assembly 3, the oil cup 22 is always hidden behind the decorative panel 4 regardless of whether the air inlet 111 of the range hood is in the open or closed state, thus satisfying the overall aesthetic requirements of the appearance of the range hood when it is on or off, and effectively preventing the formation of oil stains on the front of the oil cup 22.

[0036] The second type, compared with the first type, omits the decorative panel 4, and the flap assembly 3 can be movably connected to the smoke hood 1, and is used to open or close the air inlet 111 and the installation port, so as to hide the oil cup 22 and the installation port on the rear side of the flap assembly 3, meeting the requirement of an overall beautiful appearance when the range hood is closed. In this case, oil stains are easily formed on the front of the oil cup 22 when the range hood is turned on to draw out smoke, making the front of the oil cup 22 difficult to clean.

[0037] The third type, compared with the first type, eliminates the flap assembly 3, and the decorative panel 4 can be detachably mounted on the smoke hood 1 to open or close the mounting opening so as to hide the hidden oil cup 22 on the rear side of the decorative panel 4, thereby meeting the requirement of an overall beautiful appearance when the range hood is in the on / off state.

[0038] In this embodiment, the first method of concealing the oil cup 22 and the mounting opening is used as an example. To facilitate viewing of the oil cup 22 on the rear side of the decorative panel 4, a visible area corresponding to the oil cup 22 can be provided on the decorative panel 4. This allows the user to check the amount of oil in the oil cup 22 through the visible area, allowing the user to promptly empty the oil.

[0039] refer to Figure 1-4The smoke hood includes a shell assembly 101 and a glass panel 102. The front end of the shell assembly 101 is open to form a front opening, and the shell assembly 101 has a top air outlet 112. The glass panel 102 is detachably mounted on the front of the shell assembly 101 and covers the front opening of the shell assembly 101. An opening (not shown in the figure) is formed at the upper end of the glass panel 102. The opening includes an air inlet 111 and a decorative panel mounting opening located below the air inlet 111 and connected to the air inlet. The decorative panel mounting opening is arranged corresponding to the installation opening and is connected to the installation opening. The decorative panel 4 is detachably mounted at the decorative panel mounting opening. An inner cavity is formed between the shell assembly 101 and the glass panel 102, and the inner cavity constitutes the internal space of the smoke hood 1. In this embodiment, the smoke hood has an ultra-thin structure, and the interior of the smoke hood 1 (i.e., the inner cavity) is V-shaped or U-shaped, gradually increasing from bottom to bottom. The flap assembly 3 is configured to open or close the opening, thereby simultaneously opening or closing the air inlet 111 and the decorative panel mounted at the decorative panel insertion opening. Furthermore, an upwardly extending vertical edge 113 is integrally formed at the rear edge of the top air outlet 112. This vertical edge 113 extends into the box assembly 7 and connects to or abuts the rear side wall of the box assembly 7.

[0040] Furthermore, the mounting opening and the accommodating chamber 13 are both located in the middle of the height of the fume hood 1. This allows the oil cup 22 to be located in the middle of the interior of the fume hood 1, resolving the issue of the narrow bottom of the fume hood 1 being unsuitable for mounting the oil cup 22. In this embodiment, the range hood further comprises a water cup 21. The mounting opening comprises a water cup mounting opening 121 and an oil cup mounting opening 122, each of which communicates with the accommodating chamber 13. The water cup mounting openings 121 and the oil cup mounting openings 122 are spaced apart from each other. The water cup 21 can be movably mounted in the accommodating chamber 13 through the water cup mounting opening 121, and the oil cup 22 can be movably mounted in the accommodating chamber 13 through the oil cup mounting opening 122. The decorative panel 4 is detachably installed at the decorative panel installation port and covers the water cup installation port 121 and the oil cup installation port 122 at the same time, so that the water cup 21 and the oil cup 22 can be hidden at the back side of the decorative panel 4 at the same time, ensuring that the water cup 21 is not exposed. While satisfying the self-cleaning function of the product, it also eliminates the complicated operation of first removing the oil cup 22 and then installing the water cup 21.

[0041] refer to Figure 4In order to guide the oil stains dripping onto the top of the decorative plate 4 to the top of the accommodating chamber 13 so that the front of the water cup 21 and the oil cup 22 are not contaminated, a guide portion 41 extending toward the interior of the smoke hood 1 is integrally formed at the upper end of the decorative plate 4. The guide portion 41 extends into the smoke hood 1 through the air inlet 111 and is used to guide the oil stains flowing through it to the top of the accommodating chamber 13, and is also used to quickly guide the oil smoke into the smoke hood 1. Furthermore, the guide portion 41 includes a transverse connecting section, an upper guide section, and a lower guide section that are fixedly connected in sequence. The transverse connecting section connects the upper guide section and the upper end of the decorative plate 4 into a whole and constitutes the top of the decorative plate 4. The upper guide section and the lower guide section are both arranged from top to bottom and tilted inward. The lower guide section is used to guide the fluid flowing into it into the interior of the smoke hood and is located in the area above the water cup 22.

[0042] refer to Figure 4-7 The range hood further includes an inner cover 5 and a bracket 6. The inner cover 5 is disposed within the smoke hood 1 and is connected and fixed thereto. The inner cover 5 divides the interior of the smoke hood 1 into a smoke collection chamber 141 and a cavity 142, which are arranged vertically. The smoke collection chamber 141 corresponds to the air inlet 111 and the top air outlet 112, respectively. The bracket 6 is disposed in the cavity 142 and is connected and fixed to the smoke hood 1 and / or the inner cover 5. A receiving chamber 13 is formed between the bracket 6 and the inner cover 5. The upper end or the entire front surface of the bracket 6 corresponds to the decorative panel insertion opening. The bracket 6 is provided with an installation opening that communicates with the receiving chamber 13 and corresponds to the decorative panel insertion opening. Thus, by cooperating with the inner cover 5 and the bracket 6, a mounting space for the oil cup 22 and the water cup 21 is created in the middle of the height direction of the smoke hood 1. This allows for secure and reliable support of the oil cup and the water cup without the need for the bottom of the smoke hood 1. Furthermore, this effectively strengthens the overall strength of the smoke hood 1, making it more resistant to deformation in the event of a fall. The decorative panel 4, which covers the mounting opening, is removably connected to the bracket 6 and can be removably mounted on the front of the bracket 6 using a snap-fit ​​mechanism or a magnetic structure.

[0043] In this embodiment, the inner cover 5 covers the bottom, rear cavity wall and left and right cavity walls of the smoke collecting cavity 141, and the inner cover 5 has a smoke collecting cavity 50 that opens forward and upward, and the smoke collecting cavity 50 is used to collect oil and receive oil dripping from the top of the smoke collecting hood 1 and the top air outlet 112, and the smoke collecting cavity 50 is connected to the oil cup 22 through the oil leakage hole 512, and the air inlet 111 is connected to the top air outlet 112 through the smoke collecting cavity 50. Therefore, by arranging an inner cover 5 with a smoke collecting chamber 50 in the smoke collecting chamber 141, the strength of the smoke collecting chamber 141 can be effectively enhanced and the fall resistance of the smoke collecting hood 1 can be improved. Secondly, the oil in the smoke collecting chamber 141 and the oil discharged from the box assembly 7 and the wind cabinet assembly of the range hood can be collected to the bottom of the smoke collecting chamber 50, and then discharged into the oil cup 22 through the oil leakage hole 512, so that all the oil can be collected by the inner cover 5 and introduced into the oil cup 22, ensuring that the cavity 142 below the oil cup 22 is not contaminated by oil, and solving the problem that the existing oil cup is built-in, resulting in oil leakage in most of the inner cavities of the smoke collecting hood, or the oil cup is arranged in the middle part of the smoke collecting hood, making it difficult to collect oil.

[0044] refer to Figure 5-7 The inner cover 5 includes a bottom plate 51, which is arranged in the smoke hood 1. Its left and right ends are respectively abutted or connected to the left and right side walls of the smoke hood 1, and the rear end is abutted or connected to the rear side wall of the smoke hood 1. The bottom plate 51 divides the interior of the smoke hood 1 into a smoke collecting chamber 141 and a cavity 142 arranged up and down. An accommodating cavity 13 is formed between the bottom plate 51 and the bracket 6. Figure 4 . Furthermore, an oil collecting groove 511 that is concave downward and open upward is provided on the bottom plate 51. The oil collecting groove 511 is connected to the smoke collecting chamber 50. An oil leakage hole 512 for connecting to the oil cup 22 and a through hole (not shown in the figure) for connecting to the water cup 21 are provided at the bottom of the oil collecting groove 511. The through hole can be configured to allow a water suction nozzle to pass through. In addition, in order to better prevent the fluid from being trapped and flowing forward and downward into the cavity 142 or the accommodating cavity 13, and to make it easier for the bracket 6 to be firmly and reliably connected to the inner cover 5, the front end of the bottom plate 51 is integrally bent upward to form a flange 513. The flange 513 is located at the rear side of the upper end of the bracket 6 and is fixedly connected to the bracket 6.

[0045] The inner cover 5 also includes a back panel 52 and two side panels 53. The back panel 52 is arranged on the rear side of the bottom panel 51 and covers the entire rear cavity wall surface of the smoke collecting chamber 141. The two side panels 53 are respectively arranged on the left and right sides of the bottom panel 51 and cover the entire left cavity wall surface and the entire right cavity wall surface of the smoke collecting chamber 141. The bottom panel 51 is integrally formed with the two side panels 53 and the back panel 52, and the bottom panel 51, the back panel 52 and the two side panels 53 are enclosed to form a smoke collecting chamber 50. Furthermore, an upward extending convex edge 521 is integrally formed on the upper end of the back panel 52. The convex edge is passed through the top air outlet 112 from bottom to top and is connected and fixed to the vertical edge 113 to strengthen the strength of the top air outlet 112, thereby facilitating strengthening the reliability of the connection between the smoke collecting hood 1 and the box assembly 7, and further improving the anti-fall performance of the smoke collecting hood 1. A transverse fold 531 extending toward the interior of the smoke collecting chamber 50 is integrally formed on the upper end of each side panel 53 , and the transverse fold 531 abuts against the top of the smoke collecting hood 1 .

[0046] refer to Figure 4-7 The left and right ends of the bracket 6 are respectively connected to or abut the left and right side walls of the smoke hood 1, the rear end is connected to or abuts the rear side wall of the smoke hood 1, and the upper side of the front end is connected to the flange 513 of the inner cover 5, which is used to strengthen the strength of the smoke hood 1 and the lower end of the inner cover 1, and is also used to stably and reliably support the oil cup and water cup.

[0047] The bracket 6 includes a vertical plate 61 and a support plate 62. The support plate 62 is disposed below the bottom plate 51 of the inner cover 5. The left and right ends of the support plate 62 are respectively connected to or abut the left and right side walls of the smoke hood 1, used to support the oil cup 22 and the water cup 21. The vertical plate 61 is disposed at the lower end between the support plate 62 and the front of the inner cover 5. Its upper end is connected and fixed to the flange 513 of the inner cover 5, and its lower end is integrally formed with the support plate 62. The left and right ends of the vertical plate 61 are respectively connected to or abut the left and right side walls of the smoke hood 1. A accommodating cavity 13 is formed between the vertical plate 61, the support plate 62, and the inner cover 5. The vertical plate 61 is provided with a mounting port located below the inner cover 5 and connected to the accommodating cavity 13.

[0048] Furthermore, an oil baffle 611 extending toward the interior of the smoke hood 1 is integrally formed at the upper end of the vertical plate 61 of the bracket 6. The oil baffle 611 extends into the inner hood 5 through the air inlet 111 and is located between the top of the flange 513 and the guide portion 41. The oil baffle 611 and the guide portion 41 are respectively used to guide the oil and dirt flowing through them into the inner hood 5, so that the oil cup 22, the water cup 21, and the accommodating chamber 13 are not contaminated by the oil and dirt. A downwardly opening concave cavity is formed between the oil baffle 611 and the vertical plate 61, and the upper end of the flange 513 is inserted into the concave cavity and is in close contact with the back of the vertical plate 61. In other embodiments, the oil baffle 611 can be changed to be integrally formed and arranged at the upper end of the flange 513.

[0049] The oil baffle 611 comprises an upper and lower oil baffle section connected at an obtuse angle. Both sections are arranged from top to bottom and tilted inward, with the upper section having a greater inclination than the lower section. Of course, the lower section can also be omitted. Furthermore, positioning portions 612 are provided at the left and right ends of the vertical plate 61 of the bracket 6, each of which is configured to removably connect to the decorative panel 4.

[0050] Furthermore, the support plate 62 of the bracket 6 is integrally formed with a plurality of upwardly extending protrusions 621. All protrusions 621 are spaced apart in the left-right direction. Each protrusion 621 is used to support the oil cup 22 or the water cup 21, and is also used to strengthen the strength of the support plate 62 itself, thereby increasing the overall strength of the bracket 6. In addition, the rear end of the support plate 62 is integrally bent downward to form a vertical fold 622, which abuts or connects to the rear wall of the cavity 142. Figure 7 Thus, the bracket 6 is firmly and reliably connected to the middle of the smoke hood 1 by the vertical fold 622 abutting or connecting to the rear wall of the cavity 142 and the upper end of the vertical plate 61 connecting to the flange 513 of the inner cover 5.

[0051] Example 2

[0052] The difference between this embodiment and embodiment 1 is that the mounting port only includes the oil cup mounting port 122, or the water cup mounting port 121 and the oil cup mounting port 122 are opened to form a universal mounting port with a larger diameter, and the universal mounting port is connected to the accommodating cavity to adapt to the oil cup with a larger size. In this way, the oil cup 22 is placed inside the smoke hood 1 and supported by the bracket 6. The external cover is provided with a decorative panel 4 connected to the smoke hood 1 to form a hidden oil cup, which meets the appearance requirements and avoids the formation of oil stains on the front of the oil cup. The user does not need to clean the front of the oil cup, and the user experience is better.

[0053] The water cup 21 is configured to be removably installed in the accommodating cavity 13 by movably passing through the oil cup mounting opening 122. When the range hood's air cabinet assembly needs to be cleaned, the flap assembly 3 and the decorative panel 4 are first opened in sequence to expose the front of the oil cup 22. The oil cup is then removed, and the water cup is finally installed to clean the range hood. Because the interior of the fume hood 1 is provided with a bracket 6 for reliably supporting the oil cup 22 and water cup 21, the water cup is hidden, improving the overall aesthetics while ensuring a more secure and reliable installation. This effectively solves the problem of the water cup 21 failing to collect oil stains from the oil cup mounting feet, which can easily drip directly onto the stovetop.

[0054] Example 3

[0055] This embodiment differs from Embodiment 1 in the structure of the inner cover 5. In this embodiment, the back panel 52 or the two side panels 53 of the inner cover 5 can be omitted. Of course, the height of the back panel 52 and / or the side panels 5 can also be shortened so that the back panel 52 and / or the side panels 5 cover part of the rear wall surface and / or part of the left / right wall surface of the smoke collection chamber.

[0056] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
