Description

Extrusion type washing machine

Technical Field

The invention relates to a washing machine, in particular to an extrusion type washing machine; the washing machine mainly washes clothes in a squeezing mode, can also wash clothes in a mode of spraying water flow to wash the clothes in a large area and in a mode of raking the water flow to wash specific parts of the clothes, and has a dewatering function.

Background

There are two types of existing washing machines: impeller type and drum type. Both of these washing machines have major drawbacks. The pulsator washing machine has low washing efficiency, high water consumption, high abrasion to clothes and difficulty in cleaning collars and cuffs. The impeller washing machine mainly washes clothes by friction, the clothes placed in a washing barrel are often in a ball shape, and only a cloth layer on the surface of the ball shape can be rubbed; although the laundry tumbles in the washing tub, it is difficult to turn the cloth layer of the middle of the glob-like laundry to the outside, and it is difficult to uniformly wash the laundry. For example, clothes are wrapped in the bed sheet, and the chance of friction with the washing barrel or the impeller is not obtained all the time. Another washing mode of the impeller washing machine is to drive water flow to tumble so as to generate relative motion with clothes, and to wash dirt on the clothes by the water flow. However, when the pulsator rotates, the pulsator contacts both the clothes and the water, so that the clothes and the water start to move almost simultaneously, and the relative movement speed of the clothes and the water is very low, so that the clothes are washed by the water flow. The drum washing machine mainly breaks and generates the relative motion between water and clothes and the relative motion between the water and the clothes by falling the clothes from a high place, but the relative motion between the water and the clothes and the relative motion between the clothes are not violent; the drum washing machine also heats the washing water to soak the laundry to enhance the washing effect, but the collar and cuffs are still difficult to wash. In short, the drum type washing machine has large power consumption, long washing time and poor washing effect; and the drum washing machine is expensive in selling price. In summary, the existing washing machine has the disadvantages of low washing efficiency, poor washing effect and large abrasion to clothes. The lower washing efficiency is reflected in the waste of water, electricity and time.

The principle of washing the laundry is: the washing water and the clothes are relatively moved, and the higher the speed of the relative movement is, the higher the washing efficiency is and the better the washing effect is. Some think to spray the washing water to the clothes and wash, but can only wash the cloth layer of the surface of the clothes in a ball shape, and the cloth layer of the clothes wrapped inside cannot be washed.

The best washing method is extrusion (otherwise known as compression). Before extrusion, the clothes wrap water, the mixture of the clothes and the water is rapidly extruded, the clothes fully absorb water and wrap the water, and then the water is rapidly extruded. When the clothes washing device is extruded, water wrapped in the clothes is extruded out, and the water is extruded out to wash the clothes, so that stains are washed clean. When the fabric is extruded, water not only can wash the surface of each layer of fabric at a high speed, but also can penetrate the fabric layer at a high speed to enter gaps among yarns so as to deeply wash clothes. Thus, the cloth layer at the middle of the lumpy clothes can be squeezed to obtain the washing of the washing water. The friction washing mode is difficult to wash dirt among yarns and damage clothes, but the extrusion washing mode is easy to wash the dirt among the yarns and does not damage the clothes. The rubbing washing mode and the jet washing mode cannot wash cloth layers wrapped inside the clustered clothes, and only the squeezing washing mode can completely wash all the cloth layers inside and outside the clustered clothes. The squeezing washing mode is similar to pressing and hitting with a rod when people wash clothes manually; but is softer than the impact with a stick and therefore does not cause much wear on the clothes as the impact with a stick. Therefore, a squeeze-type washing machine (or a so-called compression-type washing machine) has been invented by many people.

However, the existing squeezing type washing machine has a plurality of disadvantages: firstly, the structure is complicated, and is bulky, and manufacturing cost is too high, and the space that occupies is big. Secondly, the dehydration function is not available. Thirdly, the reliability is poor. The current extrusion mode is that the pressing plate is extruded from top to bottom and the tray is extruded from bottom to top. If the gap between the side surface of the pressure plate or the tray and the wall surface of the washing barrel is smaller, clothes can be clamped in the gap like a wedge, the clothes, the washing barrel and a transmission device can be damaged, and the washing machine cannot run; buttons, zippers, and the like on the laundry cause more trouble if they are caught in the gap between the platen and the washing tub. If the gap is too large, the platen or tray is too small, and although the clothes are difficult to be stuck in the gap, the clothes near the wall surface of the washing barrel cannot be squeezed; this causes a conflict between washing efficiency and safety performance, and smooth operation of the washing machine is absolutely guaranteed, so that only a small platen or tray can be selected, thereby causing low washing efficiency. When the clothes are pressed upwards, the clothes are unevenly distributed on the tray which applies force upwards, and when the tray applies force, the reaction force of the clothes to the tray is unevenly distributed, so that radial pressure is generated on the shaft of the tray; when the clothes are pressed downwards, the clothes are unevenly distributed in the washing barrel, and when the clothes at the east side of the center line of the pressure plate are many and the clothes at the west side are few, the stress of the pressure plate is uneven, and radial pressure is generated on the shaft of the pressure plate. Because the pressure plate or the tray shaft is longer, the pressure plate or the tray is far away from the shaft sleeve when being stressed, and a lever effect exists, the damage to the shaft by the radial pressure is larger, the abrasion between the shaft and the shaft sleeve of the tray or the pressure plate can be aggravated, and the service life of the pressure plate or the tray is influenced. Fourthly, the washing efficiency is not high, when the pressure plate or the tray is used for extrusion, the clothes are distributed in the washing barrel or on the tray unevenly, so that the pressure on the clothes everywhere is uneven when the clothes are extruded, the pressure on the thick part of the cloth layer is large, and the thin part of the cloth layer is not extruded or is low. Fifthly, the clothes are more and less sometimes, the stroke of the tray or the pressing plate should be short when the clothes are more, and the stroke of the tray or the pressing plate should be long when the clothes are less; otherwise, the given travel cannot be finished when more clothes are available, so that the related device is blocked and stops running even to cause accidents, and the clothes cannot be extruded due to short travel when less clothes are available. The adjustable stroke of the tray or platen can significantly increase the cost of the device. Because the technology is immature, no extrusion type washing machine is put on sale at present.

Description of the drawings: the fluid pumps described herein include unidirectional fluid pumps and bidirectional fluid pumps, each of which includes a water pump and an inflator or inflator. The one-way pump has a definite suction pipe and a definite discharge pipe; however, the fluid can flow in both the forward and reverse directions in the bidirectional pump, and thus the suction and discharge pipes thereof are varied. When the fluid pump is a bidirectional fluid pump, or when the fluid pump comprises a bidirectional fluid pump, for convenience of description, the two pipes of the fluid pump connected with the outside are named a suction pipe a and a suction pipe B.

a sealing element for preventing water in the water containing barrel from leaking downwards is arranged between the water containing bottom plate and the hollow shaft; the hollow shaft can rotate in the shaft hole of the water containing bottom plate and can drive the washing barrel to rotate;

when the hollow shaft is directly connected with the outlet pipe of the water pump, a sealing element is arranged between the hollow shaft and the outlet pipe of the water pump, and the rotation of the hollow shaft does not influence the connection relationship between the hollow shaft and the outlet pipe of the water pump; when the hollow shaft is connected with the outlet pipe of the water pump through the connecting pipe, a sealing element is arranged between the hollow shaft and the connecting pipe, and the rotation of the hollow shaft does not influence the connection relation between the hollow shaft and the connecting pipe;

Description of the drawings: 1. when the pressing cloth is large, the pressing cloth moves under the driving of the fluid to press the laundry, but does not necessarily elastically deform. The larger the squeeze cloth is, the smaller the area of the washing tub for the water holes to be formed, which is disadvantageous in washing and dewatering. Therefore, the size of the extrusion cloth is proper and the extrusion cloth is elastic, so that the extrusion cloth generally generates elastic deformation when extrusion washing is carried out; however, if the laundry is very small, the pressing cloth is not elastically deformed when the pressing washing is performed. 2. Explanation of "the washing side wall is provided with a plurality of water holes penetrating through the washing tub and the water tub": although the squeezing washing work can be carried out after the water holes are formed in the whole washing side wall, if the water holes are formed in the washing side wall in the installation area of the squeezing cloth, the moving speed and the average stroke of the squeezing cloth are influenced, so that the washing efficiency and the washing effect are influenced. Therefore, the technical proposal is implemented only by arranging the water holes on the washing side wall and outside the installation area of the squeezing cloth. The latter technical feature of this technical feature is that "the water pump can drive the fluid to enter the through hole of the hollow shaft to drive the squeeze cloth to move to squeeze the laundry in the washing tub", which is a basic technical feature and needs to be ensured simultaneously with the latter technical feature, so the water hole on the washing sidewall cannot be arranged in the installation area of the squeeze cloth, and the water hole on the washing sidewall cannot be arranged in the installation area of the squeeze cloth to meet the requirements of the above two technical features simultaneously. 3. Explanation of "the middle area of the washing bottom plate is provided with a shaft hole": the shaft hole should be located within the installation area of the squeeze cloth because the basic technical feature that the water pump can drive fluid into the through hole of the hollow shaft so as to drive the squeeze cloth to move to squeeze the clothes in the washing tub is satisfied, otherwise, the basic technical feature cannot be satisfied; that is, this basic technical feature negates "the shaft hole is located outside the installation area of the press cloth".

Explanation of all the technical solutions above: 1. explanation of "installation area of the press cloth": the "installation area of the squeeze cloth" is an area on the washing tub covered by the squeeze cloth, and the laundry cannot directly contact the wall surface of the washing tub in the area because the squeeze cloth is interposed between the wall surface of the washing tub and the laundry; the shaft hole is positioned in the mounting area of the extrusion cloth, and the clothes cannot be in direct contact with the shaft hole; the shaft hole can not be touched by the hand of a person, and only the shaft hole can be touched through the extrusion cloth.

2. The original volume of the pressing space is determined by the shape, size and specific location of the pressing cloth and the washing tub where the pressing cloth is installed. If all parts of the press cloth are in contact with the washing tub without a gap, the original volume of the press space is zero or close to zero. If the parts of the squeezing cloth with more parts have a certain distance with the inner surface of the washing tub of the installation area of the squeezing cloth, the original volume of the squeezing space is larger. The original volume of the extrusion space in fig. 1 and 25 is close to zero; the original volume of the extrusion space in fig. 10, 14-18 is relatively large.

After the fluid pump is started, the pressure intensity of the fluid in the fluid pipe, the hollow shaft and the extrusion space is rapidly increased and drives the extrusion cloth to move to a certain degree, and the space between the extrusion cloth and the inner surface of the washing barrel in the installation area of the extrusion cloth is larger and larger, namely the extrusion space is larger and larger. The volume of the pressing space is constantly changed during the pressing washing. If the fluid pump is a water pump, the fluid pipe is a water pipe, the driving fluid is water, and the water flows to the hollow shaft firstly after the water pump is started; due to the presence of air in the water tube prior to activation, the press cloth may already start moving before the water reaches the hollow shaft.

3. The washing tub must be capable of containing laundry and water, and if the wall of the washing tub is provided with water holes to contain only the laundry, the laundry cannot be washed, which is common knowledge. If the wall of the washing tub is provided with water holes so as not to accommodate water, the tub needs to be added to assist the washing tub in accommodating water. Meanwhile, no water holes can be formed in the installation area of the extruded cloth, otherwise, the fluid cannot drive the extruded cloth to move or the movement speed and the average stroke of the extruded cloth are influenced.

4. When the fluid pump is a fan or an air compressor or an inflator, the fluid source is air; when the fluid pump is a water pump, the fluid source is a sink or a tank or a tub of a washing machine.

5. The extruded cloth is a cloth-like object, and can be a textile or not. The pressing cloth may or may not be an elastic cloth. If the cloth is not elastic, a part or most of the pressing cloth can be driven by fluid to move after being installed in the washing barrel, and a certain moving distance is required for effectively pressing the clothes; the less the part of the squeeze cloth can move and the smaller the moving distance, the worse the squeeze washing ability. The half-tub-shaped press cloths of fig. 5-7 and the tub-shaped press cloths of fig. 3-4 have a better press washing function even though they have no elasticity. The press cloth is preferably made of a soft elastic material, for example, a rubber skin with a thickness of 1.5mm may be used as the press cloth. Latex has great elasticity and strength if the thickness is proper, and is very suitable for producing extruded cloth. The press cloth is preferably made of a water-impermeable and non-absorbent material because the water-absorbent press cloth is not easily dried and the pressing efficiency of the water-permeable press cloth is lowered.

6. Method of coupling the edge region of a press cloth with the inner surface of a washing tub or washing lid: a plurality of threaded holes are formed in the edge area of the area, where the squeezing cloth needs to be installed, on the wall of the washing barrel or the washing cover; and a pressing strip is arranged, a plurality of screw mounting holes are respectively arranged on the edge area of the extruded cloth and the pressing strip and correspond to the threaded holes, and the extruded cloth is mounted on the inner surface of the washing barrel by the pressing strip and screws. If the wall where the screw hole is provided is thin, the thickness of the wall should be increased; or the bolt and the nut are used for connection instead. The width of the pressing strip is generally 3-15 mm, and the optimal width is 8-12 mm. The area of the pressing cloth pressed by the pressing strip is a joint area, and the other area of the pressing cloth is a non-joint area. The non-coupling region of the pressing cloth is a region capable of moving under the driving of fluid driven by the fluid pump; if the pressing cloth is a soft, elastic cloth, this region can also be elastically deformed, which participates in the pressing work of the clothing. For example, if the squeeze cloth is a flat sheet and is mounted on the washing base, the non-coupling region of the squeeze cloth is in contact with the washing base, but the non-coupling region of the squeeze cloth is separated from the washing base, and can be elastically deformed by the pressure of the fluid. This coupling facilitates the replacement of the press cloth. The extrusion cloth is also installed in a gluing mode, but the extrusion cloth is not convenient to replace.

7. When the fluid-driven extruding cloth works, no fluid can leak from the connecting area of the extruding cloth, and no fluid can leak between the hollow shaft and the shaft hole. When air or water is used as the fluid, although the operation is possible with the leakage, the washing efficiency is lowered. The water in the washing tub submerges the laundry. For the embodiments of fig. 1, 10, 14-17, the volume of the mixture of water and laundry is preferably not more than 40% of the volume of the washing tub, because the fluid source is not the washing tub, and the water level of the water in the washing tub rises when the pressure washing is performed.

8. The extrusion cloth has various shapes, which are selected according to the shape, size and other factors of the washing barrel. The drawings in the specification list extrusion cloth in various shapes.

9. The fluid pump comprises a fan, an air compressor, an inflator pump and a water pump, and also comprises a gear pump for conveying hydraulic oil and the like; the fluids for which the present invention is applicable are preferably air and water, and it is obviously uneconomical to use other fluids to drive the press cloth. However, pumps such as gear pumps for conveying other fluids can be used in the solution according to the invention for driving the press cloth by means of air or water, as long as the technical requirements are met. If the fluid pump is a fan, the fan conveys air with certain pressure to drive the extrusion cloth to move and even generate elastic deformation to extrude the clothes in the washing barrel, and when the movement and even the elastic deformation of the extrusion cloth reach a preset degree, the fan stops working and the extrusion cloth does not extrude the clothes any more; the squeezing cloth utilizes the elasticity of the squeezing cloth (if the squeezing cloth is elastic and generates elastic deformation), the pressure of the water and clothes in the washing tub on the squeezing cloth presses the air in the squeezing space out and restores the original shape of the squeezing cloth; the clothes in the washing barrel absorb water and disperse by the elasticity of the clothes; this is a wash cycle. And then starting the fan to enter the next cycle. This is a squeeze-type washing process when the fluid pump is a fan. If the fluid pump is a water pump, the water pump absorbs water from a water source and then conveys water with certain pressure to drive the squeezing cloth to move and even generate elastic deformation to squeeze clothes in the washing barrel, and when the movement and even the elastic deformation of the squeezing cloth reach a preset degree, the water pump stops working and the squeezing cloth does not squeeze the clothes any more; the pressing cloth will use its own elasticity (if it is elastic pressing cloth and elastic deformation is generated), the water in the washing tub and the pressure of the laundry to the pressing cloth will discharge the water pressure in the pressing space and restore the original shape of the pressing cloth, which is a washing cycle. And then starting the water pump to enter the next circulation. If the water level of the water source is lower than the water level in the washing barrel before the water pump is started, the water in the squeezing space can flow into the water source more easily after the water pump stops working. The fluid pump may be either a unidirectional fluid pump or a bidirectional fluid pump. Current water pumps and fans are essentially one-way pumps, i.e. they can only deliver water or air in one direction and not in the opposite direction. If the fluid pump is a bidirectional fluid pump, the fluid pump can drive the fluid to flow in the forward direction by forward rotation and can drive the fluid to flow in the reverse direction by reverse rotation; the cycle speed of the squeeze washing is faster. If the fluid pump is a bidirectional water pump, water at a water source can be driven to enter the extrusion space in a forward rotation mode to drive the extrusion cloth to move, and then the water in the extrusion space is conveyed to the water source in a reverse rotation mode. In the prior art, an axial flow water pump can be used as a bidirectional pump, but the pressures of forward rotation and reverse rotation are different to a certain extent. If the axial flow type bidirectional water pump is designed for the washing machine, the technical requirement can be met. The water pump is adopted to convey water to extrude and wash, air is arranged in a pipeline before the motor is started, but the water pump can normally work as long as water is introduced into the water pump, and the air can also participate in the work of driving the extrusion cloth to move and is always positioned above the water surface.

Conditions under which the fluid in the extrusion space automatically flows back to the fluid source: 1. elastic deformation of the extruded cloth during extrusion; 2. the clothes and water in the washing barrel have pressure on the extrusion cloth; 3. the fluid is water and the level of water in the expression space is higher than the level of the fluid source. The fluid in the extrusion space is returned to the fluid source and must have one of the following conditions: 1. the fluid in the extrusion space can automatically flow back to the fluid source, which is automatic flow back; 2. the bidirectional fluid pump can suck out and convey the fluid in the extrusion space to the fluid source, which is forced backflow; 3. the one-way fluid pump is matched with a control device such as a solenoid valve and the like for use, and can suck out and convey fluid in the extrusion space to a fluid source, which is forced backflow. In order to save the washing time, the washing apparatus should have a function of forced backflow.

10. The drive relationship can be established in a number of ways, such as by using pulleys and belts.

11. In the technical solutions 3.1, 4, 5 and 6, the axis of the hollow shaft should coincide with the central line of the washing tub to reduce the vibration during dewatering.

In summary, the technical solutions can perform the squeezing-loosening action of the clothes in a reciprocating manner, so that the clothes can be washed clean. No matter what shape and placement of the washing tub, no matter what shape and placement and elasticity of the squeezing cloth, as long as the washing motor drives the fluid pump to drive the fluid to drive the squeezing cloth to move, the motion of the squeezing cloth can squeeze the clothes in the washing tub; and the fluid entering the extruding space can flow back to the fluid source, a washing cycle can be completed, namely, the clothes can be washed. However, the rated output pressure of the fluid pump, the shape and size of the washing tub, the shape, size, elasticity and arrangement position of the extruded cloth, and the arrangement position of the hollow shaft all have certain influence on the washing effect, the washing efficiency and the production cost of the washing machine. The common specific technical features of these solutions are: the washing machine is provided with a washing motor, a fluid pump, a fluid pipe, a hollow shaft, squeezing cloth and a washing barrel, wherein the squeezing cloth can squeeze clothes in the washing barrel, and fluid can flow back to a fluid source to realize washing circulation.

Has the advantages that: compared with the prior impeller type and drum type washing machines, the technical scheme of the invention has the advantages of high washing efficiency, good washing effect, time saving, water and electricity saving and very small abrasion to clothes. Compared with the existing extrusion type washing machine, the washing machine has the advantages of simple structure, low production cost, high washing efficiency and dewatering function. The invention mainly adopts the water pump to deliver water to directly drive the squeezing cloth to squeeze the clothes, and has simple structure, low production and operation cost and small volume; when the squeezing cloth is used for squeezing the clothes, the difference of squeezing force on the clothes at each position is small, the squeezing cloth is squeezed to the weak position, the squeezing washing effect of the inner layer cloth and the outer layer cloth of the bulk clothes is basically consistent, the problem that the clothes are clamped or excessively squeezed to cause damage does not exist, and the cloth layers of the bulk clothes can be uniformly washed with the same strength; the squeezing cloth squeezes the mixture of the clothes and the water in the washing barrel, so that the washing water and the clothes can generate violent relative motion, the maximization of the relative motion speed of the washing water and the clothes is realized, and a good washing effect and high washing efficiency can be generated; and the laundry is subjected to little abrasion when pressed. This washing pattern is similar to a hand press, a foot step, or a bar stroke as used when people wash laundry manually. The area of the moving area of the pressing cloth is many times larger than the area of the hands or feet of a person, so that the washing machine is many times more efficient than manual washing. Under the condition that the concentrations of the detergents in the washing water are the same, the consumption of the detergents can be reduced by reducing the washing water, so that the cost is saved and the environment is protected.

The present invention also washes the laundry by spraying the washing water to wash the laundry. The washing water is used for squeezing the clothes when flowing in the positive direction; when the water flows reversely, the water is sprayed into the washing barrel from the water holes of the washing barrel to wash the clothes, or a part of the water flows into the washing barrel from the top of the washing barrel to wash the clothes. Therefore, the laundry is washed regardless of the flow of the washing water, saving power and time, improving washing efficiency and extending the life span of the washing machine. Aiming at the problem that stains on the neckline and cuffs of clothes are difficult to wash, the harrowing jet washing device is specially arranged, washing water with higher pressure is conveyed by a water pump to wash the neckline and cuffs of the clothes, clothes are not damaged, the washing efficiency is high, and the washing effect is good.

The squeeze type washing machine shown in fig. 80 is one of preferred embodiments of the present application. A pressure sensor is additionally arranged in a water path, and a lead of the pressure sensor is connected with a program controller. The pressure sensor has the following functions: if the water pressure does not reach the rated pressure within a reasonable time, it is not normal, because the washing water is not enough, or the washing cover is not closed, or the leakage exists in the water path.

In the schematic views shown in fig. 81 and 82, the water pump pumps the water from the tub into the pressing space to drive the pressing cloth to move upward, and the mixture of the laundry and the water is pressed together with the washing lid. Before the pressing, the wash lid should be close to or even in contact with the water surface in the wash tub, otherwise the pressing stroke may be insufficient, which is also related to the distance between the wash tub and the tub. When squeezing, the washing water flows into the water bucket from the washing side wall and the water holes of the washing cover and then flows into the squeezing space; when the washing water flows back, the washing water flows into the washing barrel from the water holes of the washing side wall and the washing cover and then is mixed with the clothes; and then entering the next cycle.

The laundry amount is measured before the washing machine is started and then the water level in the washing tub is determined. The bottom of the auxiliary squeezing cloth is contacted with water in the washing barrel, the program controller can determine the movement distance of the bottom of the auxiliary squeezing cloth according to the water level, so that the movement distance is converted into the pressure of fluid in the auxiliary squeezing space, the fluid is stopped being conveyed into the auxiliary squeezing space when the pressure of the fluid reaches the requirement, and the electromagnetic valve on the butt joint hollow shaft pipeline is closed.
