Description

A kind of rotary drum washing machine that is applicable to converter technique

Technical field

The utility model belongs to the washing machine technical field, more particularly relates to a kind of rotary drum washing machine that is applicable to converter technique.

Background technology

The rotating speed in washing machine when washing only be that per minute more than 100 changes, and when dewatering up to hundreds of even thousands of commentaries on classics, therefore, pulsator washing machine often adopts gear-box (speed-reducing clutch) to slow down, but its complex structure, cost height, noise greatly, efficient is lower; Present rotary drum washing machine nearly all is to use the single phase ac asynchronous motor as power source, though the single phase ac asynchronous motor is simple in structure, cost is low, its efficient is low and speed governing is inconvenient.

Because the speed governing of single phase ac asynchronous motor does not still have good solution so far, and adopt converter technique can realize the step-less adjustment of motor speed.

Along with progress of science and technology, converter technique can replace the speed change system (having only two kinds of rotating speeds) that existing impeller automatic washing machine had existed already eventually.But when implementing the variable-frequency washing machine technology,, influence the real efficacy of converter technique because the existence of speed-reducing clutch can make frequency conversion scope limit narrow (gearratio during the speed-reducing clutch washing is approximately 1: 5).

Studies show that, adopt converter technique control, can realize the infinitely variable speeds of motor, wash promptly that rotating speed is adjustable, dehydrating speed is adjustable, thereby make water level and the optimum Match of washing between the rotating speed become possibility.Broken through the conventional laundry apparatus motor speed uncontrollable, can only change laundry beat this traditional working mode.Because rotating speed, water level and washing beat can be realized optimum Match, so can wash the clothing of various quality, from the cashmere product to the jean, and can select washing procedure according to the booty degree of clothing, both washed totally, clothing does not does not wear and tear again.That is to say the rotary drum washing machine that uses converter technique control, its function can have more hommization, the selection space of various parameters is bigger, that the program for washing that adopts conventional laundry apparatus to realize of making over becomes is possible (for example water level and current, the optimum organization of rotating speed/beat/time etc.), can realize desirable multiple mode of washing.

Summary of the invention

The purpose of this utility model, just be to overcome the shortcoming and defect of using traditional speed-reducing clutch transmission system rotary drum washing machine to bring, provide a kind of rotary drum washing machine that is applicable to converter technique, to substitute traditional, rotary drum washing machine complicated, that manufacturing cost is higher.

The technical solution of the utility model is by the improvement to traditional automatic washing machine transmission system, concrete mainly is the improvement of using the rotary drum washing machine of speed-reducing clutch transmission system to existing, promptly use the timing clutch that does not possess deceleration, to realize and to realize good coupling with the motor of converter technique control, realize the slewing range of broad, and give full play to the usefulness of converter technique on rotary drum washing machine; The utility model makes full use of ripe friction plate technology, makes the friction disk type timing clutch to simplify transmission mechanism and manufacturing cost.By regulating frictional force, can realize " hand rubbing is washed (the bucket root changes in during washing) " function.

The utility model has specifically provides following solution: comprise outer bucket, interior bucket and interior impeller thereof, link to each other with impeller be inserted in the wash shaft in the dehydrating shaft, the dehydrating shaft that links to each other with interior bucket and the body of the washing machine of being with the clutch of water discharge dragging device, it is characterized in that it also comprises an adjustable frequency motor that links to each other with the lower end of wash shaft by shaft coupling, and above-mentioned clutch is a timing clutch, and above-mentioned wash shaft is that a upper end and bottom are square cylinder.

Therefore, as long as make above-mentioned adjustable frequency motor 20 be controlled by the electronic process controller of coded program, just can realize converter technique control.

Above-mentioned timing clutch is the upper shell that is covering mutually, in the lower house, the end is the dehydration friction plate assembly on the wash shaft of being fixed near the lower house bottom from bottom to top successively in the lower house, adopt the sliding sleeve upper and lower of splined to fix a movable friction plate respectively with dehydrating shaft, go up to support sliding sleeve and the empty stage clip on the dehydrating shaft and the adjustment nut of below and dehydrating shaft threaded engagement thereof of being enclosed within, be fixed on upper shell and lower house joint the washing friction plate assembly and on the washing friction plate corresponding with movable friction plate, and two rollers on the fork body of the pull-fork assembly that links to each other with water discharge dragging device are against the bottom of sliding sleeve inner flower-key external cylindrical surface, and washing friction plate, the shape of movable friction plate and dehydration friction plate is annular, their center line and wash shaft, the central lines of dehydrating shaft.

The utility model of constructing thus is owing to use timing clutch, therefore can good coupling be arranged with the motor of converter technique control, and realize the slewing range of broad, just can give full play to the usefulness of converter technique, realize that rotary drum washing machine can use the best of breed of multiple washing, rinsing, dehydration, reach power saving, water-saving, wash only, little, the high requirement of dehydration rate of wearing and tearing.Use the friction plate technology of maturation again owing to the utility model, thereby simplify the transmission mechanism and the higher manufacturing cost of the complexity of rotary drum washing machine greatly; And, also can realize " hand rubbing is washed (bucket and then changes in during washing) " function by regulating frictional force.
