Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a range hood with an upper opening and closing panel structure. Background Art

[0002] A range hood, also known as an exhaust hood, is a kitchen appliance that purifies the kitchen environment. Existing range hoods include top-suction and side-suction types. The side-suction type is also called a close-suction range hood. The range hood uses the principle of vortex wind pressure to absorb most of the oil smoke close to the stove in an arc form. For example, patent number CN202122563753.1 discloses a range hood with an oil smoke suction structure on the top, and patent number CN202121305172.1 discloses a range hood with a negative pressure chamber.

[0003] This type of side-suction range hood generally has a chassis in the shape of an inverted triangle or a 7-shaped structure, and provides an oil fume adsorption chamber and an oil fume adsorption port at an angle above the stove area. However, this side-suction range hood usually needs to occupy a certain layout space above the gas stove, which is not convenient for users to use higher cooking utensils. If a top-suction range hood such as that provided by patent number CN201420862340.0 is used, although it can increase the cooking activity height, the risk of oil dripping needs to be considered, and the oil fume adsorption port is far away from the cooking utensils, and the oil fume adsorption effect is poor. Therefore, it is necessary to design a range hood with a larger cooking activity height and that can effectively block oil dripping. Utility Model Content

[0028] Example

[0029] Reference Figures 1 to 3 The utility model provides a range hood with an upper opening and closing panel structure, comprising: a chassis 10, a wind cabinet 20, a fan assembly 30, a movable panel 40 and a flip assembly 50;

[0030] The fan assembly 30 is arranged on the wind cabinet 20; the wind cabinet 20 is located above the chassis 10; the chassis 10 is provided with an oil fume adsorption chamber 11 and an oil discharge chamber 12; the oil discharge chamber 12 is arranged at the rear end of the chassis 10, and an oil cup 13 is detachably arranged below; an inclined panel 14 is arranged below the oil fume adsorption chamber 11, and the rear end of the inclined panel 14 is inclined downward and connected to the oil discharge chamber 12;

[0031] A first air inlet structure 15 is provided at the rear end of the inclined panel 14 ; a main air inlet 16 is provided in the middle of the inclined panel 14 ; and the flip assembly 50 allows the movable panel 40 to move relative to the chassis 10 to cover or open the main air inlet 16 .

[0032] In the utility model, an oil fume adsorption chamber 11 and an oil discharge chamber 12 are arranged in the chassis 10; the oil fume adsorption chamber 11 is an overall structure of a top-mounted top-suction type hood chassis 10, and an inclined panel 14 is arranged below it, and the rear end of the inclined panel 14 is inclined downward and connected to the oil discharge chamber 12; so that the rear end of the inclined panel 14 and the oil discharge chamber 12 form an extended structure with a short height span that partially extends downward, and a first air inlet structure 15 is arranged at the extension structure with a short height span, which can provide a side suction port locally close to the cooking pot and the wall to maintain a certain side suction effect; while maintaining a larger cooking height space, the main air inlet 16 of the inclined panel 14 can be used as the main oil fume suction port to absorb oil fume. In addition, the main air inlet 16 can be covered or opened by the flip assembly 50 and the movable panel 40. When in use, the movable panel 40 can also be used to prevent oil from dripping directly to the bottom of the main air inlet 16, effectively guiding the oil in the oil fume adsorption chamber 11 to the oil discharge chamber 12, while preventing the oil from dripping into the cooking space.

[0033] In this embodiment, after testing, in order to maintain a certain side suction effect and avoid the oil fume exhaust chamber from being too high, and to retain a relatively high cooking activity height above the gas stove, the height span of the oil exhaust chamber 12 is between 0.3 and 1 times the height span of the oil fume adsorption chamber 11. For example, the height span of the oil exhaust chamber 12 is 0.3, 0.4, 0.5, 0.7, 0.9 or 1 times the height span of the oil fume adsorption chamber 11.

[0034] In this embodiment, after testing, in order to maintain the oil-contamination diversion effect of the inclined panel 14, the overall height span of the oil fume adsorption chamber 11 is small, and the effect of retaining the higher cooking activity height above the gas stove is retained, and the angle K1 between the inclined panel 14 and the horizontal plane is between 15 degrees and 30 degrees. For example, K1 is a design value of 15 degrees, 18 degrees, 20 degrees, 23 degrees, 25 degrees, 28 degrees or 30 degrees.

[0035] Preferably, after testing, the angle K1 between the inclined panel 14 and the horizontal plane is preferably designed to be between 20.5 and 23.5 degrees, for example, K1 is designed to be 20.5, 21, 21.5, 22, 22.5, 23 or 23.5 degrees.

[0036] In this embodiment, the upper part of the front baffle of the oil discharge chamber 12 is tilted backward and connected to the rear of the tilted panel 14; the front baffle and the tilted panel 14 form a triangular smoke cage cavity 17 that is recessed toward the inside of the chassis 10; the first air inlet structure 15 is located above the smoke cage cavity 17. Under the action of negative pressure, the oil smoke gathers in the smoke cage cavity 17 and is then sucked into the first air inlet structure 15, forming a smoke cage transition effect, which can effectively prevent the oil smoke from escaping at the first air inlet structure 15.

[0037] In some embodiments, the first air inlet structure 15 is an elongated air inlet slot extending laterally along the chassis 10 .

[0038] In other embodiments, the first air inlet structure 15 is an air inlet grid structure composed of a plurality of air inlets arranged at intervals.

[0039] In this embodiment, cage smoke baffles 18 are provided on both lateral sides of the chassis 10; the cage smoke baffles 18 are located at both ends of the inclined panel 14. The cage smoke baffles 18 are provided at both ends of the chassis 10, and are located at both ends of the inclined panel 14. When the main air inlet 16 performs adsorption work, it can effectively block the oil smoke from escaping from both sides of the inclined panel 14.

[0040] In this embodiment, the wind cabinet 20 is provided with a volute 60, and the fan assembly 30 is arranged in the volute 60; the volute 60 is arranged near the front side of the wind cabinet 20; the air inlet of the volute 60 is arranged backward and is located above the oil discharge chamber 12. The air inlet of the volute 60 is located above the oil discharge chamber 12, so that the negative pressure chamber of the fan volute 60 is connected to the top of the oil discharge chamber 12. Compared with the conventional volute 60 air inlet front structure, the overall height and space of the negative pressure chamber are larger, which can form a more stable and smooth negative pressure adsorption space, while maintaining a relatively stable negative pressure adsorption airflow, and reducing the noise of the airflow in the negative pressure chamber.

[0041] Furthermore, an oil drain block 61 is provided below the volute 60; the rear end of the oil drain block 61 is tilted downward and extends to the top of the oil drain chamber 12. The oil drain block 61 can guide the oil accumulated in the volute 60 to drip toward the top of the oil drain chamber 12, and then be diverted to the oil cup 13 for collection.

[0042] 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.
