Embodiment
The utility model embodiment ventilation fan is on the basis of the prior art domestic heating ventilation fan of similar Chinese invention patent application CN102213238A, connecting motor to its wind path switch boards drives the supporting structure of side to improve, and mainly introduces a fixed hinge bearing to this side.
This ventilation fan structure, as shown in Fig. 1 ~ Fig. 8, comprising:
---the framework 3 that sheetmetal is made;
---plastic face mask 13, is covered in the opening of framework 3;
---the volute 4 of centrifugal-fan-type, is installed in framework 3 with screw;
---centrifugal impeller 5, its center hole is placed on (main motor is installed in framework 3, because being covered by impeller 5, fails to illustrate in figure) on main motor axle 55, for volute 4 institute is around encirclement;
---heater 11, is installed on the inner side surface of volute 4 exhaust outlet place face shield 13;
---wind path switch boards 6, is positioned at volute 4 exhaust outlet, in order to switch the air-out direction of volute 4: the radial direction along volute 4 is blown toward leading to outdoor exhaust port 2, or blows toward heater 11, then loops back indoor through the warm wind port 11 that face shield 13 is offered.The terminal of exhaust port 2 has the baffle plate 1 stopping outdoor contrary wind.
Wind path switch boards 6 by being positioned at left side wall 42 that the cylinder of volute 4 exhaust outlet from volute extend, right side wall 41 supports by following way:
---be provided with left rocker bar bearing fixed block 10, it is working of plastics, insert the perforate of being fixed on left side wall 42 in self-clinching mode from left to right, it extends to the cylindrical body with this rocker bar bearing coaxial line to the right, wind path switch boards is shaped along left end with the cylindrical hole 61 of this rocker bar bearing coaxial line for 6 times, and the cylindrical body feel extended to the right by aforementioned left rocker bar bearing fixed block 10 is tightly not loose rotatably entangles;
---be provided with right rocker bar bearing fixed block 9, it is also working of plastics, turn left from the right side and to insert and self-clinching is fixed on the perforate of right side wall 41, its internal shaping is with the cylindrical hole 91 of left rocker bar bearing coaxial line, wind path switch boards 6 times along right-hand member be shaped with this rocker bar bearing coaxial line stretch out to the right external cylindrical surface 62, external cylindrical surface 62 not loosely rotatably to be entangled by cylindrical hole 91 feel is tight;
---be provided with joining shaft 8, it is positioned within the cylindrical hole 91 of right rocker bar bearing fixed block 9, and right-hand member opens rectangle groove 81 vertically, is placed on the rotating shaft 71 that stepper motor 7 stretches out left, and should be processed as corresponding flat in the two junction; Its left end is configured as flat end 82 vertically, inserts in the rectangle groove 63 of wind path switch boards 6.
According to said structure, stepper motor gets final product the clockwise and anticlockwise that transmission wind path switch boards 6 carries out several angle, switch the air-out direction of volute 4, the air-out of volute 4 is radially blown and loops back indoor toward leading to outdoor exhaust port 2 or blowing the warm wind port 11 offered through face shield 13 again toward heater 11.
In said structure, following Change In Design can be had:
---do not stretch out from exhaust outlet place during the cylinder partial plastics forming of volute 4, the left side wall 42 of the plastics of former support wind path switch boards 6 and right side wall 41 can change the sheet metal supporting element vertically upward fixed by the spot welding of framework 3 inner bottom part into and replace; Stepper motor 7 also changes into and is fixed on the fixing mounting plate of framework 3 inner bottom part spot welding;
---the standing part of former left rocker bar bearing is axle, and motion parts is hole, can change that standing part is hole into and motion parts is axle; The standing part of right rocker bar bearing is hole, and motion parts is axle, can change that standing part is axle into and motion parts is hole.
---the junction of joining shaft 8 two end and motor shaft or wind path switch boards also can be processed as other non-circular shape.
In addition, because stepper motor can stall, the current"on"time of control step motor action should be designed to complete a direction action needed time longer time than its transmission wind path switch boards, and preferably the former is 1.2 ~ 2 times of the latter, can guarantee action put in place and without the need to location and closed loop control.
