Abstract

The utility model relates to a front configured lamp top preventive window slitless machine body, which is one of the main spare parts of the exhaust hood. The slitless machine body comprises a cover plate A that is made by stamping the completely stainless steel plate and a smoke-collecting helmet B. A notching 1, a window 3 and a surrounding frame 2 with a front frame camber angle of smaller than or equal to 70 degrees are processed and arranged in the cover plate A; a base plate 4, a flange 5, a center hole 6, a front configured lamp hole 8 and a turning-over edge 7 with the same tilt angle as that of the frame 2 are processed and arranged in the smoke-collecting helmet B. The frame 2 and the turning-over edge 7 both are arranged at the height of lower than or equal to 200 mms. Through welding, grinding and polishing, the integrated slitless machine body is completed. The slitless machine body eliminates the gaps appearing after the assembling of the smoke-collecting cover and the cover plate these parts. Therefore, the machine body becomes more compact and beautiful and the maintenance and cleaning also become much faster and more convenient. And resulting from that the front frame is extroverting, when in absorbing, the upper cross section of the smoke-collecting cover B as a whole body with the machine body is smaller than that of the bottom part, and the flow rate of upper part of the oil fume is faster than that of the bottom, thereby improving the releasing strength of the configured machine body.

Description

The seamless fuselage in maintenance window uniclinal angle, preposition lamp top

One, technical field

The utility model relates to a kind of fuselage of range hood, and specifically illuminating lamp is arranged on the seamless fuselage in maintenance window uniclinal angle, preposition lamp top in the place ahead.

Two, background technology

At present, the critical piece exhaust fume collecting hood of range hood and lamina tecti, left and right sides cover plate are all with independence, split-type structural design, manufacturing, assembling both at home and abroad, therefore the junction exists either large or small slit, these slits have not only influenced the attractive in appearance of range hood appearance, the greasy place of sheltering evil people and countenance evil practices that provides more is provided, is made users bring great inconvenience to the cleaning maintenance of range hood at ordinary times.Simultaneously, this exhaust fume collecting hood is not very good for the congregational rate of the oil smoke that culinary art produces yet, and cardinal symptom shows as the extracting force of oil smoke not enough.

Three, summary of the invention

The technical scheme of the seamless fuselage technical issues that need to address in maintenance window uniclinal angle, the preposition lamp of the utility model top and proposition is: the fuselage of removing range hood makes complete machine more attractive in appearance because of the slit that assembling is occurred, and more firm, maintenance washes is also more convenient; And the increase range hood is to the extracting force of oil smoke.Specific embodiments is: get two metallic plates, a window is opened in the place ahead of processing one breach, breach on a metallic plate (has a window Gai Yuqi to be movably connected behind the one-tenth machine, can be convenient to maintenance to switch), four edge breaks have the frame of height≤200mm and the cover plate that its front bezel leans outward; On another metallic plate, strike out and comprise base plate, boss, the hole, center, preposition lamp hole, four limits turn edge, and turn edge before it to equate the exhaust fume collecting hood of (afterwards turn edge and can process with exhaust fume collecting hood integral body, also can load onto separately) with the front bezel flare angle of cover plate.Then exhaust fume collecting hood is connected the back with cover plate and makes it to become the integral body one non-dismountable, that the joint portion is seamless, remove uneven place with milling tools again with the method for welding, at last with its surface finish, polishing until eliminating the vestige that welds fully.The integral body of the range hood through being processed into like this is more solid more attractive in appearance than original fuselage, the also faster convenience of maintenance washes.And, promptly enlarged markedly the range hood that disposes this fuselage extracting force to oil smoke because the fuselage front bezel of this range hood leans outward, so its exhaust fume collecting hood top section ratio lower section is little, so the flow velocity top of oil smoke when being sucked is bigger than the bottom.

The technical scheme of the seamless fuselage in maintenance window uniclinal angle, the preposition lamp of the utility model top is: it comprises and has the cover plate A that breach 1 and four edge breaks have frame 2, by base plate 4, and boss 5, hole, center 6, four edge breaks turn edge 7, the exhaust fume collecting hood B of preposition lamp hole 8; The place ahead that it is characterized in that the breach 1 of cover plate A has a window 3 (having a window Gai Yuqi to be movably connected), all around front bezel inclination alpha≤70 of frame 2 °; Inclination alpha turns edge before the exhaust fume collecting hood B ₁Equate with the front bezel inclination alpha of cover plate A;

Frame

2 and 7 the height≤200mm of turning edge.Then exhaust fume collecting hood B is connected the back with cover plate A and makes it to become the integral body one non-dismountable, that the joint portion is seamless with the method for welding, at last with its surface finish, polishing until eliminating the vestige that welds fully.Because this product is to shape the back welding respectively by two blocks of bulk metal plates, therefore economy-combat grinding and polishing light be the integral body that a kind of nothing connects the scar weld seam again, and sump oil does not have the hiding-place; Again because the front bezel (preceding turning edge) of this fuselage leans outward, so its exhaust fume collecting hood B top section ratio lower section is little, so the flow velocity top of oil smoke when being sucked is bigger than the bottom, promptly enlarged markedly the range hood that disposes this fuselage extracting force to oil smoke.
