Description
Technical field
The present invention relates to range hood flip cover assembly, especially relate to a kind of range hood Cam-type electric flip structure.
Background technique
For overcome when range hood does not work due to public gas exhaust duct pressure large time oil smoke pour in down a chimney and pollute the defect in kitchen, the range hood of a lot of manufacturer adopts flip structure, renovates closedown, prevent oil smoke from pouring in down a chimney when range hood is not worked.The open and close of renovating of current known tilting lid type fume exhaust fan mostly adopt motor drive mode, application number as the applicant's earlier application is the three-arm ventilator flip transmission mechanism of 2013104208305, although it makes range hood have good lampblack suction exhausting effect, but it is when being in range hood working state, renovate and front panel of range hood upper cover plate between there is larger gap, when range hood is worked, part oil smoke is escaped out upward by existing larger gap, reduces smoke absorption effect; Although upper cover plate also can be reduced gap, strengthens and hold together cigarette effect with renovating to connect with hinge, because hinge always has outside part need expose, make range hood very unsightly.And because the element adopted is more, make its cost larger.
Mostly adopt rigid component due to adopted driving mechanism and renovate a Hard link, when range hood renovate closedown time, when operator or child clamp hand because of carelessness, closed limit switch is not touched owing to renovating not yet to close to put in place, therefore control gear does not make motor stalls, thus makes to renovate and to be held by hand tighter and make hand injuryies.The defect that tong hurts sb.'s feelings is renovated for overcoming range hood, the drive motor that the range hood of some manufacturer production is renovated adopts direct current generator, renovate when hand is clamped and make motor stalls because making by resistance circuital current increase to a certain degree trigger control device, reach the defect of avoiding renovating and hindering hand, but due to direct current generator stop operating before increase because electric current increases the dynamics making to renovate tong and cause the cusalgia of hand, moreover use direct current generator to renovate drive motor, can make to renovate noise when opening and closing very large.Adopt the flip cover assembly of the hardwired driving mechanism of rigid component in addition, it generally adopts limit switch to control the position of renovating open and close, therefore to make to renovate just to put in place in closed position, make it not only attractive in appearance but also reliable, meticulous adjustment will be carried out in the position of limit switch, thus add cost of labor.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art existence, there is provided a kind of structure simple, hold together cigarette better effects if when range hood is worked and can prevent from renovating the range hood Cam-type electric flip structure of hindering hand, the technological scheme that technical solution problem of the present invention adopts is, a kind of range hood Cam-type electric flip structure, comprise motor, motor cabinet, renovate, cam, mobile hinge, it is characterized in that, described motor cabinet is fixedly mounted on the housing being positioned at range hood and on the mounting plate be fixedly connected with described housing, described motor is fixedly mounted on described motor cabinet, described cam is fixedly connected with the output shaft of described motor, closed limit switch and unlatching limit switch are arranged on described housing or described mounting plate, described mobile hinge comprises connecting base A, by the intermediate plate that fulcrum A and described connecting base A are rotatably connected, by the connecting base B that fulcrum B and described intermediate plate are rotatably connected, described intermediate plate has a certain degree through bending shape
θ, described connecting base A is fixedly connected with the top plate lower end inner face of range hood front portion, and described connecting base B is fixedly connected with the described upper end inner face renovated.
Further, baffle plate is fixedly connected with described renovating.
Further, described cam is bending cam.
Further, 60 degree≤
θ≤ 120 degree.
Further,
θ=90 degree.
Working principle of the present invention is, as shown in Fig. 1 to 12, upon power-up, described in the control gear main control module instruction of range hood, the output shaft of motor is clockwise, at Fig. 1, 3, 5, 7, 9, be counterclockwise rotate in 11, described cam is driven to rotate counterclockwise, thus renovate described in making and rotate counterclockwise, when described renovate the position going to setting time, trigger motor stalls described in the instruction of range hood control gear main control module, namely described motor stops operating, described renovating stops operating, gap between the top plate lower end of the upper end of renovating now and described front panel is one thin-line-shaped, when making fume exhaust, upwards escape in gap between the upper end of renovating described in oil smoke no longer passes through and the top plate lower end of described front panel.
When range hood is closed, just in time contrary with above-mentioned situation, former each parts in rotating counterclockwise change in rotating clockwise above, thin-line-shaped gap between the top plate lower end of described upper end of renovating and described front panel is progressively broadening, to last due to the described Action of Gravity Field renovating self, described renovating is closed completely, and motor stalls described in the instruction of trigger control device main control module, the gap between the top plate lower end of the upper end of renovating now and described front panel is again in thin-line-shaped.
In various embodiments of the present invention, under normal circumstances, namely under accurate situation is debugged in the position of closed limit switch, describedly renovate in closing process, when described renovate contact with range hood shell edge time, closed limit switch work, and motor stalls described in the instruction of trigger control device main control module; The position of closed limit switch debugging and in coarse wherein a kind of situation, describedly renovate in closing process, when described renovate contact with range hood shell edge time, described closed limit switch does not work, described motor and driving mechanism still work, but because described cam is not connected with described renovating, therefore described cam does not have pulling force to described renovating, although described in renovate and stop operating, described motor and cam still rotate, until closed limit switch work, motor stalls described in the main control module instruction making control gear.Therefore this kind of structure and working method make to require to reduce to the adjustment accuracy of limit switch, thus improve manufacturing efficiency, alleviate cost of production.
Renovate in closing process described, when it turns to certain position, have hand to be sandwiched in renovate described in side or below and between range hood shell edge time, as shown in figure 15, described cam is not connected with described renovating, according to mechanics principle, therefore hand be only subject to described in renovate the effect of the left direction component of gravity, very little owing to now renovating with the angle of vertical curve, so the power that hand is subject to is very little, can not hand be damaged; Even and if when clamping hand, motor is running as usual, when the work of closed limit switch, motor just stops operating, when need by clamp hand-held go out time, renovate described in only need counterclockwise firmly rotating a little, just can by hand-held go out, renovate then under the effect of himself gravity, described in renovate and get back to vertical state, cover the mesh of web plate, reach the object that the present invention prevents from hindering hand.
The invention has the beneficial effects as follows, make that range hood flip structure is simple, debugging simplifies, hold together cigarette better effects if when range hood is worked, can prevent renovating tong and hurt sb.'s feelings, owing to adopting built-in mobile hinge structure, make the outward appearance of range hood more attractive in appearance.
