Describe the preferred embodiments of the present invention in detail below with reference to accompanying drawing.With undefined object, for example concrete composition structure and element, just in order to assist those skilled in the art to fully understand apparatus of the present invention, but apparatus of the present invention are not so limited.
A kind of door switch unit of ice dispenser comprises a kind of mode of operation of the mechanical power for the preceding distributor door 7 that opens or closes ice dispenser automatically.When promoting the ice selector switch, rotate ON/OFF bar 6 by the automatic operation of microcomputer, the preceding distributor door 7 that is installed in then on the ON/OFF bar 6 is opened or closed.Door switch unit also comprises upper casing 10 and the following casing 11 that removably is engaged with each other, be installed in down the direct current generator 1 in the casing 11, but forward direction or reverse rotation, secondary master gear 3 is meshed with gear on worm 2 on being installed in power transmission shaft, and three grades of master gears 4 are meshed with secondary master gear 3.
Shown in Fig. 1 and Fig. 2 A, Fig. 2 B, the axis of rotation 5c of fan-shaped output gear 5 inserts the precalculated position of upper casing 10 and following casing 11, and the interconnection by motor 1 and gear 2,3,4 makes output gear 5 forward directions or reverse rotation.When output gear 5 forward directions rotated, shaft-like wheel hub 5a promoted, rotation connecting rod 6a, to push the helical spring 8 around ON/OFF bar 6, has so just opened door 7.When output gear 5 reverse rotations, helical spring 8 discharges from impaction state, and shaft-like wheel hub 5a is near connecting rod 6a, and door 7 has just been closed like this, can not produce the bump and the sound.
As shown in Fig. 3 A and Fig. 3 B, 5 one kinds of structures of the fan-shaped output gear of this device have several functions.The lever 9a that comes actuating doors and signal detection switch 9 from the outstanding shaft-like wheel hub 5a of output gear 5 and inclined-plane wheel hub 5b manipulation connecting rods 6a at first, upwards.Equally, the lower trapezoid wheel hub 5e of insertion gathering sill 10a and 11a moves or stops along gathering sill 10a and 11a, and gathering sill 10a and 11a form on upper casing 10 and following casing 11 respectively.When ON/OFF bar 6 rotates in predetermined angular, that is to say that 50 °, this angle is to open the door and close the door necessary, trapezoidal wheel hub serves as obturator, and like this, door just can excessively not rotate.
More specifically, according to the inclined-plane wheel hub 5b that is relatively arranged on shaft-like wheel hub 5a opposite, when 5 rotations of fan-shaped output gear, shown in Fig. 4 A and 4B, the lever 9a that is installed in down the signal detection switch 9 on the casing 11 moves upward with received signal along the inclined-plane of inclined-plane wheel hub 5b.When fan-shaped output gear 5 reverse rotations, the lever 9a of signal detection switch 9 moves downward to send signal along the inclined-plane of inclined-plane wheel hub 5b.Therefore, by signal, can detect that the door of ice dispenser is opened or close.
Shown in Fig. 5 A and 5B, shaft-like wheel hub 5a is arranged in the connecting rod 6a of ON/OFF bar 6, and the answer element of helical spring 8 is arranged on 6 li on ON/OFF bar.At ordinary times, door 7 is closed by the magnetic force around the helical spring 8 of ON/OFF bar 6.When user's operation commutator button, output gear 5 is by the rotation of microcomputer forward direction.In this case, as shaft-like wheel hub 5a during near connecting rod 6a, shaft-like wheel hub 5a utilizes the also big power of elastic force of the helical spring 8 that produces than the rotation by output gear 5 to promote connecting rod 6a consumingly.Therefore, shown in Fig. 5 A, ON/OFF bar 6 rotates so that door 7 is opened, and keeps door opening state.
Open simultaneously when door 7, the ice batch operation is finished, and output gear 5 reverse rotations are to fastening position.In this case, connecting rod 6a utilizes helical spring elastic-restoring force automatic reverse rotation.Simultaneously, shown in Fig. 5 B, 6 reverse rotations of ON/OFF bar and keep closed condition so that door 7 is closed.
In the time of in off position, owing to connecting rod 6a is not meshed with output gear 5, and close by the elastic-restoring force of helical spring 8, if user's manual unlocking door 7, door can be opened easily, and does not produce restraint forces or catch phenomenon.When user's hand leaves the door opened 7, utilize the restoring force of helical spring 8, door 7 returns back to the home position, i.e. closed condition.
In this embodiment, fan-shaped output gear 5 direct and upper casing 10 and 11 assemblings of following casing, but preferably, stainless axle is inserted into axis of rotation 5c to strengthen the strength of rotating back shaft.
Reason is that fan-shaped output gear 5 promotes annular connecting rod 6a, thereby fan-shaped output gear 5 has tangible active force and moment of torsion.In order to stand load, axis of rotation 5c must have big outer dia.
Yet, because not being narrow space at ice dispenser, the axis of rotation 5c with big outer dia do not form, each stainless axle is inserted into axis of rotation 5c reinforcing axis of rotation, thereby stands tangible active force and moment of torsion.As shown in Figure 6, three grades of master gears 4 are used to stop element to be damaged, and this damage is owing to the user is that issuable excessive abnormal load causes when opening distributor door 7 and pulling.
More specifically, stainless packing ring 22 is installed between pinion 20 and the gear 21, between gear 21 and the following fixed bar 21a stainless packing ring 23 is installed, from preventing only to produce excessive rotary load, this excessive rotary load is when excessive revolving force produces, and stainless packing ring 22 and 23 slides rotation and produces.
As shown in Figure 7, cables under power input 14,15,16,17 and the utilization of signal detection power cable in the casing 11 and constitute overall structure, and be arranged in parallel with each other.Four CP lines are arranged in parallel with each other in casing, and the profile of casing is corresponding with the shape of relative casing.
Article two, the CP electric wire is connected with the power supply of motor 1, and so that electric energy to be provided, two other CP electric wire is connected with detection signal with signal detection switch 9 by cable.
In the past, the signal detection part setting separated from one another of the input power of motor 1 and signal detection switch 9 so just need be connected to each other by two or more relative housings and connecting line.Yet, in apparatus of the present invention, the CP line is pressed into the housing similar shapes with following casing 11 forcibly, and power input 14,15,16,17 and signal detection power cable utilize cable and constitute overall structure, and be arranged in parallel with each other, thereby they are assembled into a housing.Therefore, help reducing cost, improve assemble ability, shorten working hours.
In apparatus of the present invention, the axis of rotation 5c of fan-shaped output gear 5 is designed to have 50 ° angle, with this ON/OFF angle as distributor door 7, thereby promotes the connecting rod 6a of ON/OFF bar 6 with identical phase difference on same axis, and opens door 7.The center gathering 12.5mm of the center of fan-shaped output gear 5 and shaft-like wheel hub 5a like this, produces enough big power and spurs connecting rod 6a, ON/OFF bar 6 and door 7.Design is disturbed other elements to stop like this, as ON/OFF bar 6, upper casing 10 and following casing 11 etc.
As mentioned above, as the replacement of the conventional solenoid that opens or closes ice eliminator door in electric power motor performance mode, direct current generator, spur gear and fan-shaped output gear are assembled with formation electric power rotation mode, thereby stop impact sound or buzzer when camber line exchanges.Distribute the door open-close operation peace and quiet of borneol to carry out swimmingly.And, to avoid the electroshock that high pressure produces, and compare to realize the conventional apparatus that cost reduces with utilizing alternating current generator, the quantity of element has reduced in a large number.Therefore, refrigerator specious, and space that can the maximum using refrigerator.Further, be comfortable because ice dispenser operates in when distributing ice cube, can be comfortable when the user uses, can not get a fright yet.
