Abstract

The utility model relates to a roller cleaning mechanism for a washing machine. A column-shaped swinging roller is installed on the inner wall of a fixed washing tank, and clothes to be washed are arranged in an annular flexible washing bag. The washing bag is sheathed on the swinging roller, (the external side of the washing bag corresponding to the swinging roller can be additionally provided with a squeezing roller), and the washing bag is driven to rotate by the swinging roller. Thus, the clothes are repeatedly dipped, pressed and rolled in a liquor drainage mode for washing, and the circular washing bag can also be supported to rotate at a high speed for drying the clothes through a radical telescoping mechanism of the swinging roller. The method of impacting the surfaces of clothes by water flow of a general driving wheel or a drum-type washing machine is changed, and detergent and water can fully wash the fiber of the clothes. Thus, the cleaning degree is obviously enhanced, and the detergent, the water and the time are saved.

Description

The roller type wiper mechanism of washing machine

This technology belongs to the manufacturing technology of a kind of novel washing machine wiper mechanism in the field of household appliances.

The washing machine of producing both at home and abroad is divided into thumb wheel and cylinder two major types at present, and washing principle mostly is: washing clothes is immersed in the water, driven the current rotation or driven the clothing rotation by cylinder by thumb wheel, mainly rely on the form of water impact that clothing is cleaned.This mode of washing is relatively more difficult to the Fouling Cleaning that immerses clothes fiber inside, and wash degree is not high enough, and the quantity of water and washing agent is all bigger, and wash time is also longer.

In order to improve wash degree, save washing agent simultaneously, water and time, we have designed a kind of novel roller type wiper mechanism of washing machine.

This wiper mechanism mainly by: fixing (with the oval column of long axis direction upper and lower settings) side has the cleaning cabin of hatch door, with be installed in the cabin, its axis is vertical swing roller with cleaning cabin sidewall, and can be enclosed within on the swing roller (interior ring diameter greater than roller diameter) annular flexible cleaning bag and constitute, during use washing clothes is contained in the annular cleaning bag, again cleaning bag is enclosed within on the swing roller, put into an amount of washing agent and water in cleaning bottom, cabin, start swing roller afterwards and drive the cleaning bag rotation, make washing clothes circulation immersion and (utilizing cleaning bag that clothes weight brings and the pressure between the roller) roll extrusion discharge opeing in washing agent or water, reach the purpose that clothing is cleaned.

Swing roller is designed to column at the cleaning state, the one end places the hatch door center, the other end is fixed in the bearing chamber of cabin sidewall by it, and roller shaft stretches out on out of my cabin the part belt pulley is housed, and the power of swing roller is obtained by motor by this belt pulley.

For strengthening the rolling squeeze function, in cleaning the cabin, the annular cleaning bag outside, the squeezing roller that has cursor has been installed, can change between the spacing of squeezing roller and column swing roller and two-wheeled pressure by cursor to washing clothes, this part structure and operation principle are: the other end of cursor is fixed on its power transmission shaft, power transmission shaft stretches out out of my cabin, and partial fixing has its transmission arm that its main transmission lever also is housed, be connected by the unidirectional strong point and extension spring between main transmission lever and the transmission arm, when duty changes, can leave cleaning bag by motor through drive squeezing rollers such as transmission arms by the main transmission lever that screw rod and nut slider drive, or rely on cleaning bag through drive squeezing rollers such as extension springs, determine roller work (position) state and pressure by the size of main transmission lever corner.(also can use the method that changes main swing roller operating position, change the duty and the pressure of roller).The column swing roller surface of this mechanism be provided with and cleaning bag between anti-skidding projection with segment or other non-sharp shape.

The annular flexible cleaning bag that this mechanism uses, desirable high strength (chemical fibre class) material soft again and that do not deposit color makes in the selection, similar ring-type tubular on the ring bag constructions, radical length after the tube diameter should be got it and is crushed is less than the axial length of roller working portion, ring diameter is greater than the diameter of column swing roller in the ring bag, should have closeable clothing filler on ring bag surface, gravitational equilibrium during ring bag rotation for the benefit of, can in the cross section of ring bag, make separation net at filler place and this mouthful to side position, to encircle the bag be divided into about two chambeies, clothing can be seated in the bag equably during use.Ring bag commonly used is little mesh-structured, when this ring bag cleans and dries in the rotation of loading clothing, helps the infiltration and the discharge of cleaning fluid.The smart soft clothing of part also can adopt fluid-tight ring bag splendid attire, needs to inject in bag an amount of water and washing agent during cleaning.

For increasing the drying function of this mechanism to clothing, can adopt many swing rollers to change the method for spacing, support annular cleaning bag and rotate the drying effect of playing clothing at a high speed; Also can on a swing roller, be provided with radial expansion mechanism, support annular cleaning bag rotation with its extension and dry.For example the column swing roller can be decomposed into: the front and back supporting disk, arcuation blade sections and axle four major parts, both the swing roller periphery was provided with gyroaxis along two ends one side that it vertically is decomposed into some arcuations, wherein an end opposite side is provided with the blade sections of power transmission shaft, the front and back supporting disk is provided with corresponding blade gyroaxis locating hole, the blade gyroaxis will be loaded in the locating hole of supporting disk, can establish than platter surface near the back supporting disk part of cleaning the cabin inwall, turning round the axle center with blade on card is the center of circle, get blade gyroaxis to the distance between the power transmission shaft and make radius, by the blade drive shaft position that constitutes the column swing roller is starting point, open one and hold the arc stopper slot that blade drive shaft slides, the line that the groove terminal point can be limited in blade its gyroaxis and power transmission shaft is the radial development state of swing roller, a bit locate to blade drive shaft, to be equipped with the blade retainer spring in (or near) on the extended line of the mid point of the supporting disk back side, back blade drive shaft arc stopper slot and the blade gyroaxis line of centres, when blade drive shaft is subjected to the moment loading of unrestricted direction, this blade will be that rotate at center (in the stopper slot scope of power transmission shaft) with its gyroaxis, constitute and be positioned (contraction) by spring and stopper slot to clean or (expansion) drying two states.Here make the controlling organization and the operation principle thereof of the arcuation blade rotation on the column swing roller be: on the cleaning cabin sidewall corresponding with supporting disk behind the swing roller, being equipped with can be along the slide-and-guide piece of roller radial displacement (to the arcuation blade drive shaft), when normal wash and drying duty, this guide pad is controlled by its transmission levers, be in outside the rotary track of (is the center with the swing roller axle) arcuation blade drive shaft, when becoming the drying state by cleaning, (under swing roller stall situation) transmission levers control guide pad (to the swing roller center) moves, enter fully to guide pad guide rail the inner in the rotary track of blade drive shaft (is the center with the swing roller axle), (be when roller rotates, guide blades power transmission shaft drive blade is that rotate at the center with its gyroaxis smoothly, the guide pad upper rail should be set as inclined-plane or cambered surface) at this moment can start swing roller (turning to) slow rotation along blade is deployable, the swing roller blade will be launched by the slide-and-guide piece one by one, when blade launches (the radially state that its gyroaxis and power transmission shaft line are swing roller) fully, blade drive shaft should break away from guide pad, and crosses guide pad guide rail outer end and continue to rotate the drying state of setting up.When changing cleaning (or clothing pack into taking-up) state by drying, the outer end that (under roller stops the rotation situation) moves to its guide rail outside with guide pad enters in the rotary track of (is the center with the swing roller axle) blade drive shaft (during deployed condition) fully, can start swing roller rotates at a slow speed round about, blade will rotate the roller state that is shrunk to along guide pad one by one, this moment, blade drive shaft and guide pad broke away from, and swing roller can be rotated further into the cleaning state.

The extruding of rolling is cleaned and the support drying work of swing roller is carried out with correlation timing, here adopt cover (sensor, motor, a screw rod) control and a drive system, this system drives the squeezing roller displacement by the nut slider that is connected with squeezing roller main transmission lever on the screw rod, have only when squeezing roller during away from the column swing roller, this nut slider could contact with the transmission levers of (the arcuation blade drive shaft) slide-and-guide piece, by this lever drives slide-and-guide piece displacement, to set up the duty that requires of swing roller.The duty of squeezing roller and swing roller is divided to systems control division by (being connected in squeezing roller main transmission lever) state sensor and is transmitted work state information, and the machine system control section is according to this information and panel instruction decision programme for machine.

The advantage of this technology is: it can allow washing agent or water wash between the fiber of washing clothes more fully, take dirt more up hill and dale out of, this washing methods is similar manually to be washed by rubbing with the hands, its good effect is: the wash degree that improves clothing, save the consumption of washing agent and water, (utilizing many annular cleaning bags) can realize reusing washing agent easily, cleans earlier many batches of clothings successively and dries successively.Can also reduce wash time.
