Description
Technical Field
[0001] The utility model relates to the technical field of range hoods, in particular to a range hood with an oil overflow prevention and smoke exhaust structure. Background Art
[0002] Range hoods and integrated stoves are both widely used kitchen appliances. Usually, a range hood (or integrated stove) includes a range hood body, a volute, a fan, a check valve and a smoke exhaust pipe. The fan and the volute are arranged in the range hood body; the check valve is arranged above the range hood body, aligned with the air outlet of the volute, and is used to connect the smoke exhaust pipe. However, the existing check valve is usually installed flush with the upper panel of the range hood or slightly sunken below the upper panel of the range hood; when the oil smoke is continuously sucked and discharged through the smoke exhaust pipe, the oil will adhere to the inner wall of the check valve and the volute, and accumulate in the installation gap between the check valve and the upper panel. After further filling and accumulation, it is easy to overflow to the outside of the upper panel through installation analysis, making it difficult to keep the upper panel clean and tidy, and there is a safety risk of affecting the electronic components of the upper panel.

[0024] Example
[0025] Reference Figures 1 to 4 The utility model provides a range hood with an anti-oil overflow smoke exhaust structure, comprising a range hood body 10, a volute 20, a fan 30 and a check valve 40; the fan 30 and the volute 20 are arranged in the range hood body 10; the check valve 40 is arranged above the range hood body 10;
[0026] The upper panel 11 of the range hood body 10 is provided with a smoke exhaust port 12; the air outlet of the volute 20 is provided with a first mounting flange edge 21, which is aligned and installed below the smoke exhaust port 12; a second mounting flange edge 41 is provided below the air inlet of the check valve 40, which is aligned and installed above the smoke exhaust port 12; the first mounting flange edge 21, the upper panel 11 and the second mounting flange edge 41 are provided with corresponding mounting holes 50; the upper panel 11 is formed with a sealing boss 13 by stamping; the sealing boss 13 is arranged around the outer periphery of the smoke exhaust port 12, and can fit the outer side of the first mounting flange edge 21.
[0027] In the utility model, the first mounting flange edge 21, the upper panel 11 and the second mounting flange edge 41 are provided with corresponding mounting holes 50, and the check valve 40, the upper panel 11 and the volute 20 can be quickly locked and installed by bolts and welding nuts; and the sealing boss 13 formed by stamping the upper panel 11, the sealing boss 13 is arranged around the outer periphery of the smoke exhaust port 12, and can fit the outer side of the first mounting flange edge 21, so that the oil and dirt in the installation gap between the check valve 40 and the upper panel 11 accumulates on the inner side of the sealing boss 13. When a liquid oil and dirt layer of a certain thickness is accumulated, the oil and dirt cannot enter the installation gap and cannot overflow to other areas of the upper panel 11 over the sealing boss 13. The oil tank keeps the upper panel 11 clean and tidy, and protects the electronic components in other areas of the upper panel 11.
[0028] In this embodiment, in order to facilitate alignment of the smoke exhaust port 12 , the first mounting flange edge 21 and the mounting holes 50 of the second mounting flange edge 41 , the smoke exhaust port 12 is a square structure; the first mounting flange edge 21 and the second mounting flange edge 41 are square structures corresponding to the smoke exhaust port 12 .
[0029] In this embodiment, the check valve 40 is made of plastic material; the outer edge and the inner edge of the second mounting flange 41 extend downward with edge reinforcement rib walls 42; the edge reinforcement rib walls 42 on both sides of the inner and outer sides and the upper panel 11 are surrounded to form an oil collecting sealing chamber 60. The edge reinforcement rib walls 42 on both sides of the inner and outer sides can strengthen the strength of the second mounting flange 41, and at the same time can be attached to the upper panel 11 and surrounded to form the oil collecting sealing chamber 60, and oil can accumulate and fill in the oil sealing chamber to form a sealing oil film. When the oil film accumulates to a certain thickness, it can prevent the oil in the installation gap from further infiltrating.
[0030] Specifically, the second mounting flange 41 is further provided with a middle reinforcing rib wall 43; the middle reinforcing rib wall 43 is located between the two side edge reinforcing rib walls 42, and can separate the oil collecting sealing chamber 60 into two sealing chambers. The middle reinforcing rib wall 43 can further improve the strength of the second mounting flange 41, and at the same time separate the oil collecting sealing chamber 60 into two sealing chambers, thereby achieving a double sealing oil film sealing effect.
[0031] Furthermore, in order to better enhance the physical strength of the second mounting flange 41 and increase the fitting receiving area between the lower portion of the second mounting flange 41 and the upper panel 11 , the middle reinforcing rib wall 43 is connected with a mounting hole 50 or an annular support platform 44 .
[0032] In this embodiment, the height of the sealing boss 13 is higher than the height of the inner cavity of the oil collecting sealing chamber 60. When the inner cavity of the oil collecting sealing chamber 60 is completely filled with oil to form an oil film, the height of the oil film is lower than the height of the sealing boss 13, so that the oil film cannot cross the sealing boss 13 and overflow to other areas of the upper panel 11.
[0033] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
