Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

In the description of the present invention, it is to be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in a generic and descriptive sense only and not for purposes of limitation, as the disclosed embodiments of the invention may be oriented in different directions and the directional terms are intended to be illustrative and should not be construed as limiting, such as "upper" and "lower" are not necessarily limited to directions opposite to or coincident with the direction of gravity. Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1 to 2, a range hood includes a fume collecting hood 1, a fan frame 2 disposed above the fume collecting hood 1, and a fan housing disposed outside the fan frame 2.

The front side of the smoke collecting cover 1 is formed with a first receding groove 11 which is depressed inwards from the surface and is used for installing a switch. A fixing plate 4 which is sunken towards the direction of the fan frame 2 from the fan outer cover 3 and is used for installing a display device is arranged between the fan outer cover 3 and the front side of the fan frame 2. Because of being provided with first groove 11 of stepping down, cause fan frame 2 and collection petticoat pipe 1's front end unable connection for range hood's complete machine intensity is not enough, consequently will set up the lower extreme of fixed plate 4 on fan dustcoat 3 and extend to first groove 11 of stepping down, fixed plate 4 is dismantled with collection petticoat pipe 1, fan frame 2 and fan dustcoat 3 respectively and is connected. Because set up first groove of stepping down 11, cause collection petticoat pipe 1 and fan frame 2's front end to be unable to be connected, cause the intensity of complete machine not enough, consequently connect into a whole through fixed plate 4 with collection petticoat pipe 1, fan frame 2 and fan dustcoat 3 to the rigidity of range hood's complete machine has been strengthened.

The second groove of stepping down 31 that caves in to the top is formed to the front side lower extreme of fan dustcoat 3, and first groove of stepping down 11 and the second groove of stepping down 31 position correspond and communicate to in installation fixed plate 4. The shape of fixed plate 4 and the adaptation of second groove 31 of stepping down, fixed plate 4 all have first hem 41 on left side, right side and top, and fixed plate 4 can dismantle with fan dustcoat 3 through first hem 41 and be connected. Fan housing 3 and fixed plate 4 can be dismantled and be connected for fan housing 3 need not whole stretch forming, only need use the bender bend alright, thereby reduced fan housing 3's the manufacturing degree of difficulty, promoted fan housing 3's manufacturability.

The fixed plate 4 is provided with a first sinking platform 42 which is sunken towards the fan frame 2, and the fixed plate 4 is connected with the fan frame 2 at the first sinking platform 42 through screws. The fixing plate 4 is connected with the smoke collecting cover 1 through screws by extending to the lower end of the first abdicating groove 11.

A first accommodating space for accommodating the switch is formed on the first receding groove 11, a second accommodating space for accommodating the display device is formed on one side of the fixing plate 4 away from the fan frame 2, the first accommodating space and the second accommodating space are communicated, and the switch can be arranged in the first accommodating space, and the display device can be arranged in the second accommodating space. A display device integrated with a switch function can be arranged in the total accommodating space of the first accommodating space and the second accommodating space, so that a larger display size can be obtained, and better use experience is achieved.

Referring to fig. 3 to 4, the top of the smoke collecting cover 1 is formed with second sinkers 12 corresponding to the left and right sides of the fan housing 3 for placing the left and right sides of the fan housing 3 and preventing the left and right sides of the fan housing 3 from moving in the left and right directions, respectively. The top of the smoke collecting cover 1 is provided with a flange 13 which extends downwards from the top of the smoke collecting cover 1 and prevents the fan outer cover 3 from displacing towards the front side, corresponding to the front part of the fan outer cover 3. The second sinking platform 12 and the flange 13 are arranged, so that the number of fixing screws can be effectively reduced, and the assembly efficiency is improved.

The rear side of the fan housing 3 is open, and the fan housing 3 includes second flanges 32 bent and extended from the rear sides of the left and right sides to the middle, respectively. First through-hole 321 and second through-hole 322 that the interval was arranged about the top of second hem 32 was seted up, the rear side of fan frame 2 corresponds first through-hole 321 department and has seted up by the draw-in groove 21 of top undercut, corresponds second through-hole 322 department and has seted up third through-hole 22, and first through-hole 321 can pass through screw fixed connection with draw-in groove 21, second through-hole 322 and third through-hole 22 with the draw-in groove 21.

Referring to fig. 5 to 9, since the overall size of the fan housing 3 is relatively large and deformation is likely to occur during transportation, in order to better protect the fan housing 3, the second through hole 322 of the fan housing 3 and the third through hole 22 of the fan frame 2 are fixed by screws, so that the fan housing 3 and the fan frame 2 are fixed together, when the whole range hood is transported to a user's home for installation, the screws for the second through hole 322 and the third through hole 22 are removed, and then the screws are screwed into the first through holes 321 to be clamped with the clamping grooves 21, thereby well solving the contradiction between transportation deformation and the requirement of the user for easy disassembly and assembly of the whole range hood. The screw can restrict the movement of the upper end of the fan housing 3 in the front-back left-right direction after being clamped with the clamping groove 21, and the lower end of the fan housing 3 is in limit fit with the second sinking platform 12 and the flange 13, so that the movement of the whole fan housing 3 in the front-back left-right direction is restricted.

Along with the technical development of trade, range hood weight on the market is more and more heavy, expects range hood can not take off under the condition of complete machine at user's family, can clean spiral case, impeller etc. in order to ensure that the range hood complete machine just can accomplish the cleaning under the on-hook state to fan housing 3 will satisfy display device's installation demand, the utility model discloses the problem of taking out of fan housing 3 under the on-hook state has been solved well, only needs to lift fixed plate 4 and fan frame, the connecting screw of first groove 11 of stepping down, upwards lifts fan housing 3 again, makes the screw break away from draw-in groove 21, just can take off fan housing 3, and the protecgulum of dismantling fan frame 2 at last can begin cleaning.
