Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 5, the air outlet pipe connecting structure of the range hood comprises an air outlet seat 100, an air outlet pipe 200 and a fixing sleeve 300, wherein the upper section of the air outlet seat 100 is in a U shape and comprises an inner ring 110 and an outer ring 120, and four positioning protrusions 121 which are uniformly distributed in the circumferential direction are protruded out of the outer wall of the outer ring 120; the lower end of the air outlet pipe 200 is provided with a flange 210, and the flange 210 is embedded between the inner ring 110 and the outer ring 120; the fixing sleeve 300 has an inverted U-shaped cross section and includes an inner ring 310 and an outer ring 320, the inner ring 310 is embedded between the inner ring 110 and the outer ring 120 and is pressed against the flange 210 downward, an inverted L-shaped groove 321 matched with the positioning protrusion 121 is formed in the inner wall of the outer ring 320 in a concave manner, a vertical portion of the groove 321 penetrates through the outer ring 320 downward, a horizontal portion of the groove 321 is formed in a concave manner to form a limiting groove 321a, the shape of the limiting groove 321a corresponds to that of the positioning protrusion 121, the positioning protrusion 121 is rotatably clamped into the horizontal portion of the groove 321 and is embedded into the limiting groove 321a, and the limiting groove 321a is tightly attached to.
During the installation, establish fixed cover 300 in advance in the tuber pipe 200 top, aim at the protruding 121 and insert of location of air outlet seat 100 with the recess 321 of fixed cover 300 again, then with fixed cover 300 rotatory certain angle after, make protruding 121 imbed spacing groove 321a again in location, thereby accomplish the quick installation of tuber pipe 200, during the dismantlement, then press fixed cover 300 downwards, make protruding 121 in location deviate from spacing groove 321a, the fixed cover 300 of reversal rotation again, just can make fixed cover 300 and the separation of air outlet seat 100, just also say that the dismouting of tuber pipe 200 need not with the help of other mounting tools, the dismouting is very convenient. Wherein, spacing groove 321a can effectively avoid location arch 121 to deviate from recess 321 because of lampblack absorber work vibrations, and the connection of air-out pipe 200 is more reliable.
Wherein, the location arch 121 is the setting of circular cylindricality, and spacing groove 321a is arc setting and with the shape phase-match of location arch 121 for the spacing groove 321a is more smooth in the embedding of location arch 121 or deviate from, and it is more laborsaving to go out the dismouting of tuber pipe 200.
The bottom of the inner ring 110 of the air port seat is transversely provided with an oil leakage hole 111 in a penetrating manner, so that oil condensed in the flue and flowing back to a position between the outer ring 120 and the inner ring 110 can be discharged through the oil leakage hole 111, and the phenomena of oil accumulation and oil overflow are avoided. Four oil leakage holes 111 are uniformly distributed along the circumferential direction of the inner ring 110 so as to fully cover the oil accumulation area, the anti-overflow effect is better, and unnecessary potential safety hazards are avoided.
The groove 321 is formed in the fixing sleeve 300, which inevitably weakens the strength of the fixing sleeve 300, and in order to meet both the strength requirement and the thickness requirement of the fixing sleeve 300, the outer ring 320 is provided with a reinforcing part 322 protruding from the position corresponding to the groove 321, so as to improve the overall strength of the fixing sleeve 300 and reduce the manufacturing cost.
The outer ring 320 is provided with a through hole 323 corresponding to the horizontal portion of the groove 321. Through setting up through-hole 323 to make things convenient for the installer to observe the assembly condition, make things convenient for fixed cover 300 once only injection moulding recess 321 simultaneously, the drawing of patterns is simpler.
Have annular fender wall 324 along outer ring 320 upwards vertical extension, when partial oil smoke spills over from the outside of air-out pipe 200 promptly, also more easily keep off the inner wall liquefaction of wall 324 at annular, then flow back under the action of gravity to the user subsequently concentrates the clearance, and the lampblack absorber uses sanitation and hygiene more.
The lower end of the air outlet seat 100 is provided with a flange part 130, and the bottom surface of the flange part 130 is concavely provided with an annular groove 131 for embedding a sealing ring, so that the installation sealing property between the air outlet seat 100 and the range hood body is better.
The lower end of the air outlet pipe 200 extends horizontally inwards to form a horizontal step 220, an annular convex edge 230 vertically extends upwards along the inner edge of the horizontal step 220, and the annular convex edge 230 is sleeved outside the inner ring 110, so that the air outlet pipe 200 is positioned and installed, installation and matching are more accurate, and oil smoke is not easy to leak. Wherein, the upper part of the inner ring 110 is arranged in a taper shape to guide the annular convex edge 230 to be sleeved in the inner ring 110, thereby further improving the installation convenience.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
