Implementation

[0031] refer to Figures 1 to 13 As shown, a household range hood is shown, comprising a housing 1 , at least two fans 2 are arranged on the top of the housing 1 .

[0032] Common household range hoods are equipped with only one fan on the top or back of the housing, and the fan is installed in the middle. A household stove has at least two burners on the left and right. Regardless of whether one or both burners are used, the generated fumes need to be sucked toward the center by the fan, rather than being collected and absorbed directly above the burners, and the suction power of the fan is discounted. In this embodiment, there are at least two fans 2, which are arranged horizontally along the housing 1. For this purpose, the overall size of the housing 1 can be increased, and the coverage of the stove is larger. In addition, the two fans cover the two burners respectively, and the fumes generated by the two burners are sucked more directly, which greatly improves the suction power of the entire range hood.

[0033] Furthermore, there are three fans 2 , which are arranged along the width direction of the box body 1 .

[0034] As shown in the attached drawings, when there are two fans 2, the optimal width dimension of the range hood housing 1 is 90CM, and the depth is 600CM. For stoves with a larger coverage area, the width dimension of the housing 1 needs to be increased, for example, the optimal dimensions can be 1200CM and 1500CM, and the depth is 600CM. For the widened housing 1, it is preferred to arrange three fans 2 along the width direction of the housing 1.

[0035] Furthermore, the box body 1 includes a front cover plate 11 , and control keys 21 for independently controlling the three fans 2 are respectively arranged on the front cover plate 11 .

[0036] As shown in the attached drawings, three independently controlled control keys 21 allow the user to freely select one or more fans to work according to the usage of the stove head, so as to achieve efficient and energy-saving ventilation. Since the fans 2 are covered in the box body 1 and cannot be seen, the control keys 21 for independently controlling the three fans 2 are installed on the front cover plate 11 and correspond to the positions of the three fans 2 one by one, so that the user can select which fan to work more simply and intuitively. The control key 21 is preferably a simple and intuitive piano-key switch, which has a simple structure and is more convenient for maintenance and replacement, and has higher performance reliability.

[0037] Furthermore, the box body 1 includes a front cover plate 11, a left side plate 12, a right side plate 13 and a back plate 14 which are spliced ​​to each other and fixedly connected by connecting pieces.

[0038] Since the box body 1 is relatively large, it is not convenient to perform overall bending processing. This piece structure is more convenient for independent bending processing, has low requirements for bending equipment, and is conducive to mass production. And the overall strength after splicing is better. As shown in the attached figure, the splicing of each plate is bent into a folding edge to facilitate alignment and splicing, and the connecting parts can be rivets, bolts, etc.

[0039] Furthermore, the upper parts of the front cover plate 11, the left side plate 12 and the right side plate 13 are bent and contracted inward, and together with the rear back plate 14, form a guide cavity 15, the top of the guide cavity 15 is covered with a top plate 16, the fan 2 is fixed to the bottom surface of the top plate 16, and the top plate 16 is provided with a through hole for installing the air outlet of the fan 2.

[0040] As shown in the accompanying drawings, the front cover plate 11, the left side plate 12 and the right side plate 13 are divided into two parts, the lower part is straight-cylindrical, and the upper part is bent and contracted inward, and its inner wall can guide and concentrate the oil smoke entering the guide cavity 15 to the fan 2.

[0041] Furthermore, reinforcing brackets 3 are fixed to the inner sides of the upper parts of the front cover plate 11, the left side plate 12 and the right side plate 13 respectively, and the lower edges of the front cover plate 11, the left side plate 12 and the right side plate 13 are bent inward to form flanges 17, and the reinforcing bracket 3 and the flanges 17 of the corresponding front cover plate 11, the left side plate 12 and the right side plate 13 are detachably connected via a reinforcing lining plate 4.

[0042] As shown in the accompanying drawings, three reinforcing brackets 3 are respectively pasted and fixed along their respective width directions to the inner sides of the upper parts of the front cover plate 11, the left side plate 12 and the right side plate 13 that are bent and contracted inwardly. The flanges 17 at the lower edges of the front cover plate 11, the left side plate 12 and the right side plate 13 are U-shaped in cross-section, so that the lower open edge of the spliced ​​box body 1 has a certain thickness, making the range hood more textured as a whole, and a cavity is formed after being connected with the three reinforcing lining plates 4, which can be used to hide corresponding wires, accessories, etc., while maintaining a certain inward bending angle of the front cover plate 11, the left side plate 12 and the right side plate 13, further ensuring the overall opening and closing of the box body 1 while also making the overall strength of the box body better.

[0043] Furthermore, a slot 18 is provided on the flange 17, a slide buckle 41 which can be inserted into the slot 18 is protruded from the bottom of the reinforcing lining plate 4, and the top of the reinforcing lining plate 4 is fastened to the reinforcing bracket via a fastener.

[0044] As shown in the attached drawings, the slide buckles 41 under the two side reinforcement linings form an L shape along the width direction of the left side plate 12 and the right side plate 13, so that they can be inserted into the slots 18 of the left side plate 12 and the right side plate 13, slide inwards to position, and then be connected to the reinforcement lining 4 by bolts. The slide buckle 41 under the middle reinforcement lining extends in a direction perpendicular to the front cover plate 11, so that the middle reinforcement lining can be pushed in horizontally and then inserted into the slots 18 of the front cover plate 11, and then connected to the reinforcement lining 4 by bolts. When installing, the three reinforcement linings 4 slide in the same direction, which is very convenient for disassembly and assembly.

[0045] Furthermore, the reinforcing lining plate 4 includes a front lining plate 42, and a front-high and rear-low oil-conducting and exhaust steel mesh 5 is detachably connected between the front lining plate 42 and the rear back plate 14, and a laterally extending oil cup bracket 6 is fixed to the lower inner edge of the rear back plate 14 below the oil-conducting and exhaust steel mesh 5, and an oil cup 7 is movably arranged in the oil cup bracket 6.

[0046] As shown in the attached drawings, a large-sized oil-conducting and exhausting steel mesh 5 that matches the large-sized box 1 covers the bottom of the box 1, making the range hood simple and elegant as a whole. The oil-conducting and exhausting steel mesh 5, which is high in the front and low in the back, is preferably tilted at an angle of 12°, which is more conducive to the oil stains being introduced into the oil cup 7 along the oil-conducting and exhausting steel mesh 5. The oil cup bracket 6 is arranged close to the rear back panel 14, and the oil cup 7 is placed in the oil cup bracket 6, which can partially block the user's line of sight, and the oil stains in the oil cup 7 will not be seen too easily, which plays a role in hiding the oil cup and improving the cleanliness of the range hood.

[0047] Furthermore, a step notch 61 is provided in front of the oil cup bracket 6 for the oil cup 7 to enter and exit.

[0048] As shown in the accompanying drawings, the two sides of the oil cup bracket 6 are limited by the flanges of the left plate 12 and the right plate 13, the back is limited by the back plate 14, and a small baffle is bent on the front side to prevent the oil cup 7 from slipping out. A step groove 61 is formed between this small baffle and the oil guide and exhaust steel mesh 5 to facilitate the removal or installation of the oil cup 7.

[0049] Furthermore, the front edge of the oil cup 7 is folded outward and extends laterally out of the handle plate 71 .

[0050] As shown in the accompanying drawings, the hand-held plate 71 extends toward the operator for easy gripping. Further, the outer edge of the hand-held plate 71 is folded upward to form a thickened anti-slip edge to prevent the oil cup 7 from being easily removed due to oil stains.
