Abstract
A range hood riser, characterized by: the planetary gear transmission mechanism is composed of a first sun gear, a second sun gear, an internal gear, a first planet gear and a second planet gear, wherein the first sun gear, the internal gear and the first planet gear form the first planetary gear transmission mechanism, the second sun gear, the internal gear and the second planet gear form the second planetary gear transmission mechanism, the first sun gear is installed on a motor rotating shaft, the rotating shaft of the second sun gear is connected with a rotating disc of the first planet gear into a whole and is positioned on the axis of the rotating disc of the first planet gear, and the screw is installed at the central position of the rotating disc of the second planet gear. Compared with the prior art, the scheme has the advantages that: the transmission mechanism has even stress, low transmission noise and stable lifting of the range hood, and prolongs the service life of the lifting frame of the range hood.
Description
Technical field:
The present invention relates to a kind of device of getting rid of cooking fume gas, particularly a kind of range hood lifter.
Background technology:
After traditional range hood was installed, this machine lower edge and kitchen range identity distance be 70-80 centimetre, and the exhaust gas volumn of distributing in the cooking operation process altered a great deal from fixing, and during fried food, flue gas sharply increases especially.Be not difficult to find that this moment, flue gas had only part outdoor from the range hood discharge, it is indoor to still have a considerable amount of flue gases to spread in, and produces to pollute.Chinese patent CN02218035.4 provides a kind of range hood lifter, and its transmission mechanism is that motor directly drives screw rod after by a pair of gear graduation and rotates, and its defective is that the transmission noise is bigger, and service life is shorter.
Summary of the invention:
The objective of the invention is to regulate the residing height of range hood, make flue gas fully drain into outdoor by range hood and smoke exhaust pipe thereof for providing a kind of and the matching used lifter of range hood.
A kind of range hood lifter, comprise crane 1, guide rail 2, bracket 3, bottom bracket 4, circuit board 5, motor 6, screw rod 8, wherein crane 1, guide rail 2 and screw rod 8 lay respectively between bracket 3 and the bottom bracket 4, crane 1 is done elevating movement along guide rail 2, motor 6 drives screw rod 8 by planetary gear mechanism and rotates, screw rod 8 drives crane 1 and range hood lifting, it is characterized in that: planetary gear mechanism is by the first sun gear 7a, the second sun gear 7a ', internal gear 7b, the first planetary gear 7c, second planetary gear 7c ' formation, the first sun gear 7a wherein, internal gear 7b, the first planetary gear 7c constitutes first planetary gear mechanism, the second sun gear 7a ', internal gear 7b, second planetary gear 7c ' formation, second planetary gear mechanism, the first sun gear 7a is installed in motor 6 rotating shafts, the rotating disk of the rotating shaft of the second sun gear 7a ' and the first planetary gear 7c is connected as a single entity, and be positioned on the axis of rotating disk of this first planetary gear 7c, screw rod 8 is installed on the center of rotating disk of the second planetary gear 7c '.Planetary gear mechanism adopts three planet gear drives, perhaps four lines star gear drive; The circuit board 5 that is used to control motor 6 work is arranged in bracket 3.
Press " just changeing ", " counter-rotating ", " location " switch of being connected with circuit board, the forward or reverse of control motor 6, and crane 1 lifting puts in place, motor drives cranes 1 and range hood lifting to suitable height through planetary gear mechanism 7, screw rod 8, for producing the few cooking of flue gas, range hood is in a high position; Produce the special many fried class cookings for flue gas, then make range hood be in low level, outdoor to guarantee that flue gas fully drains into.
With prior art relatively, advantage of the present invention be transmission mechanism stressed evenly the transmission noise is low, the range hood lifting is steady, has prolonged range hood crane service life.

The specific embodiment:
Embodiment 1
A kind of range hood lifter, as shown in Figure 1 and Figure 2, power of motor is 60 watts, voltage is 12 volts, rotating speed is that per minute 5000 changes, and adopts three planet gear drives, and the first sun gear 7a and second sun gear 7a ' number of teeth are 6 teeth, the internal gear 7b number of teeth is 48 teeth, the first planetary gear 7c and second planetary gear 7c ' number of teeth are 19 teeth, and screw rod 8 screw threads are M16 * 2, and the lifter width is 30 centimetres, highly be 48 centimetres, the lifting distance of range hood is 36 centimetres.
A kind of range hood lifter, as Fig. 1, shown in Figure 4, power of motor is 60 watts, and voltage is 12 volts, and rotating speed is that per minute 5000 changes, adopt four lines star gear drive, screw rod 8 screw threads are M16 * 2, and the lifter width is 30 centimetres, highly are 48 centimetres, the lifting distance of range hood is 36 centimetres, and all the other structures are identical with embodiment 1.
