Description
Technical field
The present invention relates to a kind of kitchen appliance, be specifically related to a kind of range hood.
Background technology
At present, the island formula that relatively is suitable for installing in open kitchen begins to become a part of consumer and likes the kitchen appliance selected for use, but this type of range hood complex structure and the service behaviour that exist in the market are poor.Publication number is the mounting structure that the Chinese utility model patent of CN2913901Y and CN101349466A discloses a kind of island formula range hood, this mounting structure comprises four bracing frames, the upper end of each bracing frame is connected with the fixed mount that is installed on ceiling, the lower end of each bracing frame is connected with the motor case of this range hood respectively, the side of bracing frame is provided with elongated groove, is stuck in the groove and by fourth end flanging towards user's decorative panel to be hung on the screw of fixed mount.On this range hood, being used for supporting the fixed mount of whole range hood, only be four plate-like pieces, and the whole erection constitutional detail is various, has brought very big trouble for the installation of machine.Need a kind of structure optimization, island formula range hood easy to install and use on the market.
Summary of the invention
The technical problem to be solved in the present invention provides the range hood that a kind of fuselage height can be regulated.
The present invention with the technical scheme that solves above technical problem is: a kind of range hood, comprise upper hanger, be supported in the blower fan system on the described upper hanger, the exhaust fume collecting hood housing parts, be connected in the smoke pipe of leading between described blower fan system and the described exhaust fume collecting hood housing parts, it is characterized in that, also comprise connecting frame in the middle of following that connecting frame in the middle of the going up that a side being connected with described upper hanger opens wide and front side that is connected with described exhaust fume collecting hood housing parts by the lower end open wide, described down in the middle of the top of connecting frame insert described going up in the middle connecting frame bottom.The range hood of the technical program, high flexible is adjustable, and simultaneously, the design of related part makes things convenient for the factory process manufacturing.Design such as connecting frame in the middle of upper and lower because the two all is that three bread enclose, the structure of recording quantity, like this, has just made things convenient for their bending techniques when processing and manufacturing.
The concrete embodiment according to the present invention, range hood of the present invention, it is characterized in that, described down in the middle of connecting frame top and described in the middle of the bottom of connecting frame be provided with the screw hole of consistent size along short transverse, described down in the middle of the top of connecting frame insert in the middle of described the going up the length in the connecting frame bottom and can pass screw hole overlapping on the two by screw and determined.This kind design can be carried out connecting frame in the middle of upper and lower fixedly connected with the cheap relatively connected mode of cost on the basis of above technical scheme.
Further, cause whole syndeton lax unable for fear of the structure of opening wide owing to a side of down middle connecting frame, the banding structure that further improvement connects effect need be set, range hood of the present invention, it is characterized in that, be provided with at least one linking arm between two edges of the bottom of the front side of opening wide of described down middle connecting frame.
Further, more easy for the assembling that makes range hood of the present invention, range hood of the present invention is characterized in that, it further comprises a following link, and this time link is provided with hangs control, and described down middle connecting frame is provided with hook.During assembling, can be by the exhaust fume collecting hood housing parts be connected to down on the link, and the assembled part integral body after connecting be suspended to be connected in the middle of in the middle of following on the connecting frame on the hook on the connecting frame, pass through connector afterwards again, carry out further fastening as screw.
According to the embodiment of the present invention, range hood of the present invention is characterized in that, connecting frame (20a) all is the one frame-type part of making by metal plate punching, bending in the middle of described down middle connecting frame (20b) and described the going up.In the range hood of the technical program, because connecting frame all adopts metal plate punching to carry out the one frame-type part of the fabrication process of bending again in the middle of upper and lower, comparing has relevant numerous and diverse Element Design structure of range hood now, has reduced the manufacturing cost of complete machine widely.
Further, according to the embodiment of the present invention, range hood of the present invention is characterized in that, described upper hanger roughly is the U type.Such upper hanger structure, simple in structure, in the use of carrying range hood distortion little, simultaneously, more help strengthening and the structure relevant with the support of blower fan system carried out the even more ideal setting of effect in the structure of hanger.
Range hood according to claim 5, it is characterized in that, preferably, in order to save the numerous and diverse manufacturing cost of bringing of manufacturing process and the structure of upper hanger to be simplified, increase its support strength simultaneously, range hood of the present invention is characterized in that, is provided with stiffener on the diapire of described U type upper hanger.
