Description

Washing Machine

The present invention relates to a washing machine, and more particularly, by changing the rotational driving force of the driving means into a linear reciprocating motion using a rotating body and a link mechanism having a rotating protrusion, the laundry is stretched / relaxed when the reciprocating body moves in the tank. It relates to a washing machine capable of repeating the operation to produce a laundry effect close to hand washing.

The structure of the general washing machine and its operation will be briefly described with reference to FIGS. 1 and 2.

1 is a cross-sectional view showing a general configuration of a conventional washing machine. The conventional washing machine has a water tank 102 in the outer housing 101. On the inner bottom of the dewatering tank 103, a rotary blade 105 is provided to be rotatable. The dehydration shaft 109 is fixed to the dewatering tank 103, and the rotary blade shaft 107 is fixed to the rotary blade 105. The dehydration shaft 109 is provided on the outer circumference of the rotary blade shaft 107.

The rotary blade shaft 107 and the dehydration shaft 109 are provided with a switching mechanism 106, and the rotation of the motor 104, which is provided at the outer bottom of the water tank 102 by the switching mechanism 106, is a rotary blade. It is selectively transmitted to the shaft 107 and the dehydration shaft 109.

The switching mechanism portion 106 is operated by the clutch lever 117 and the solenoid 118. The motor 104 is provided with the motor rotating shaft 104a. The belt transmission mechanism 114 rotates the drive shaft pulley 113 fixed to the motor rotation shaft 104a, the driven side pulley 108 fixed to the rotary blade shaft 107, and the drive shaft pulley 113 to follow the rotation of the driven side pulley. It consists of a belt 116 to be transmitted to 108.

In the conventional washing machine having the above configuration, during washing, the rotation of the motor 104 is transmitted to the rotary blade shaft 107 by the action of the belt transmission mechanism 114 and the switching mechanism portion 106 to rotate the rotary blade shaft 107. Only by rotating, the washing process is performed.

At the time of dehydration, the rotation of the motor 104 is transmitted to the dehydration shaft 109 and the rotary blade shaft 107 so that the rotary blade shaft 107 and the dehydration shaft 109 are integrated to rotate at a high speed, thereby performing dehydration treatment.

In recent years, the bubble cleaning function has the above-mentioned configuration and simultaneously generates bubbles in the washing liquid during washing, so that the detergent is dissolved in the washing water and the washing liquid easily penetrates into the garment, thereby improving the washing effect. Added washing machines are attracting attention.

The invention disclosed in Japanese Patent Application Laid-open No. Hei 2-46233 as one conventional example of a washing machine having a bubble cleaning function will be described below with reference to the drawings.

2 is a cross-sectional view of the washing machine having the bubble cleaning function disclosed in the above publication. The washing machine includes an outer housing 151, a water tank 152 embedded in the outer housing 151, a dehydration tank 153 installed in the water tank 152, and a rotation transmission mechanism unit provided at an outer bottom of the water tank 152. 159 and the air supply unit 160. The dewatering tank 153 has a dewatering hole 154 and a rotary vane 155 is provided at its inner bottom.

The rotation transmission mechanism portion 159 is composed of a motor 158, a belt 157, and a switching mechanism portion 156. The washing machine having such a configuration works in the same manner as the basic example to rotate the rotary vane 155 and the dehydration tank 153. The air supply unit 160 includes an air pump 161, an air pipe 162, and an automatic time switch 163. The automatic time switch 163 is provided in the operation panel 165 provided on the upper part of the washing machine main body, and is connected to the air pump 161. The air pipe 162 is connected to the air discharge port 164 provided at the bottom of the air pump 161 and the water tank 152 in order to supply the air obtained by the air pump 161 into the water tank 152. In addition, a drain pipe 166 is provided at the bottom of the water tank 152.

In the washing machine having the above structure, by operating the automatic time switch 163 during washing, the air pump 161 is operated only for a predetermined time to supply a predetermined amount of air. The air is supplied into the water tank 152 at the air discharge port 164 through the air pipe 162. The air supplied into the water tank 152 is supplied to the washing liquid in the water tank 152 and the dewatering tank 153 through a gap between the rotary vane 155 and the dewatering tank 153 or the dewatering hole 154.

The air supplied in this way generates bubbles in the washing liquid, promotes the dissolution of the detergent into the washing water and the penetration of the washing liquid into the garment, thereby improving the washing effect.

In the above conventional example, there is a problem described below. Since the air pipe 162 is connected to the bottom face of the water tank 152, it has a part provided in the position lower than the bottom face of the water tank 152. FIG. Thus, the washing liquid containing dirt such as fat, dirt, sand, seams, etc. remains in such a part even after washing, and the dirt is easily deposited in the air pipe 162. Therefore, it causes a problem in supplying air into the water tank 152. In the above-described conventional example, bubbles are generated in the washing liquid in a presoak step, and then the usual washing treatment is performed. That is, during the washing process, the washing process is performed by the rotational force of the main rotary blade 155. Therefore, damage was easily caused to the laundry, especially the fabric of silk and wool garments.

The problem with the washing machine described so far is merely an example, and there are many improvements in addition to this.

However, the problem described below is a problem related to the basic washing method in the washing machine, the solution of this problem will be more important than others.

In the conventional washing machine, the washing blade is rotated by a so-called motor, and the washing method is a method in which a vortex generated by the rotating blade causes friction with the laundry to wash away the dirt remaining in the laundry.

This is fundamentally limited in its laundering effect compared to artificial methods (traditional laundry methods). The traditional method of washing, ie, hand-hand washing, is to rub the laundry directly and brush off any foreign matter or dirt on the laundry, so that the laundry is cleaned without damaging the laundry.

The washing method is used in combination with the friction method to remove the laundry time very efficiently. Basically, the last technology of the washing machine is to come up with products that are close to hand washing.

Therefore, the present invention is different from the conventional rotary washing method by the washing wing, by stretching the laundry linearly reciprocating a predetermined shape of the washing actuator (reciprocating body) to the left and right in a state in which the laundry is freely placed in the flowing wash water / stretching / It is an object of the present invention to provide a washing machine that allows the laundry to have a light washing effect by repeating the relaxation operation.

A feature of the washing machine of the present invention is that the reciprocating body 10 having a predetermined shape is adopted as a driving ear element. The reciprocating member 10 is moved back and forth or left and right by a normal driving means and a predetermined link mechanism mechanism.

The reciprocating body 10 is disposed in the water tank 20 shown in FIG. 5 and the shape thereof is shown as a semi-circle in the figure, but is not necessarily limited to such a shape, and if it can impart the shaking to the wash water Of course, it may be configured in a form such as 1/3 or 1/4 circle or quadrangular or similar shape.

In the middle of the reciprocating body 10, a rotating body 30 for imparting a reciprocating force to the reciprocating body 10 is provided. The rotating body 30 is constituted by a pair of rotating plates 31 and 32 and an upper member 33 covering the rotating plates 31 and 32. In addition, the rotating body 30 is connected to a pair of operation link 40 for transmitting a driving force to the reciprocating body (10). That is, when the rotary plates 31 and 32 are assembled, the rotary protrusions 31a and 32a are formed in opposite directions, respectively. Therefore, the rotation protrusions 31a and 32a have a motion displacement relationship of repeating the 'maximum width-minimum width' with each other as the rotation body 30 rotates.

In the lower portion of the rotating plate 32 disposed on the lower side of the rotating body 30, there is provided a V-belt pulley 34 having a V-belt groove for transmitting power from a drive motor (not shown). .

Connection holes 42 are formed at both ends of the operation link 40. The two connection holes 42 receive the rotary projections 31a and 32a and the link pins 52 of the slider 50 to be described later to transfer the power from the driving means to the reciprocating body 10. will be.

The slider 50 will be described in more detail. The slider 50 is provided with a flat plate 54 arranged horizontally, i.e., horizontally with respect to the ground, a vertical plate 55 standing up on both ends of the flat plate 54, and an upper end of the vertical plate 55. The connecting plate 56 is formed, and the guide hole 58 formed in the lower portion of the vertical plate 55.

The flat plate 54 is fixedly assembled with the reciprocating body 10 through the vertical plate 55 and the connecting plate 56, and at the same time, the link pin 52 and the rotary protrusions 31a and 32a. It is assembled to enable the link movement to the operation link 40 and the rotating body 30 through. Reference numeral 12 is a lower plate of the reciprocating member 10, 14 is a bolt hole for connecting the connecting plate 56 drilled in a suitable portion of the lower plate 12, 35 is a V-belt spanning the V-belt pulley 34 to be.

The V-belt is not necessarily limited to such power transmission means, and for example, a timing belt or the like can also be used.

The guide hole 58 is fitted with a rod-shaped guide body 60 which is firmly fixed to the washing machine main body, thereby preventing rocking during the left and right (or front and rear) reciprocating movements of the slider 50 and the reciprocating body 10. It works smoothly.

Referring to FIG. 5, the water tank 20 includes a main space part 22 in which the reciprocating body 10 is disposed, and a part for isolating the rotor 30 and the link mechanisms from laundry. Iii) A vertical plate guide hole 26 for receiving the vertical plate 55 is formed in the partition wall 25 formed of the space portion 24 and separating the main space portion 22 and the sub space portion 24. .

Due to the formation of the vertical plate guide hole 26, parts such as the reciprocating plate 10 can be smoothly left and right reciprocated, and together with the guide hole 58 and the guide body 60, It also serves as an operational guide.

The tank 20 of such a configuration can be changed in any way according to the shape of the reciprocating plate 10 and the application of the driving mechanism, and other components, for example, the rotating body 30. It is a matter of course that the parts such as the slider 50 are appropriately changed in correspondence with the change of the driving means or the shape change of the reciprocating plate 10.

The special washing operation of the washing machine of the present invention configured as described above will be described.

5 and 7, when the driving motor (not shown) is driven, the driving force is transmitted to the V-belt pulley 34 along the V-belt 35 and the pulley is coaxially integrally with the rotating body 30. Since it is provided, the rotating body 30 rotates. As the rotor 30 rotates, the rotary protrusions 31a, 32a formed on the respective rotor plates 31, 32 of the rotor 30 rotate, and the rotational force is transmitted to the link mechanism mechanism to reciprocate. Changes to That is, the rotational driving force is changed into a linear reciprocating motion by the operation link 40, the link pin 52 and the rotary projections 31a, 32a, and the reciprocating force is reciprocated through the slider 50 (10). Is delivered).

As a result, the rotation by the drive motor is changed into a linear reciprocating motion while passing through the mechanisms, causing the reciprocating body 10 to swing left and right as shown by the arrow shown in FIG.

FIG. 7 shows the distance X of the two rotation protrusions 31a and 32a separated from each other with maximum distance, and the positions of the rotation protrusions 31a and 32a are mutually inverted. It is the minimum distance from each other.

Therefore, in the water tank 20, the washing water and the detergent for washing, including the feeling of laundry is put into the state as the reciprocating body 10 moves to the left and right, and the contents fluctuate.

The swinging state is very fast and instantaneously, so that washing water and detergents infiltrate the laundry and change the volume of the fabric, and in a moment, it repeats the process of vacuuming and releasing a part of the laundry. The washing effect is excellent.

8 is an explanatory view for explaining the flow state of the washing water during the operation of the reciprocating body of the present invention, Figures 9a and 9b is an explanatory view for explaining the operating state of the laundry departure prevention piece of the present invention.

In these figures, the laundry separation prevention piece 16 provided in the reciprocating body 10 of this invention is shown. First, referring to FIG. 8, when the reciprocating member 10 reciprocates to wash, the washing water and the laundry in the water tank 20 move in the direction of the arrow. Therefore, as shown in FIGS. 9A and 9B to prevent the laundry from escaping from the space between the two reciprocating bodies 10 by the oscillating motion of the reciprocating member 10, The laundry separation prevention piece 16 is installed at left and right ends to reciprocate with the swing of the reciprocating body 10.

As a result, the space between the reciprocating bodies 10 by the laundry departure prevention piece 16 forms a closed space to prevent the laundry from being randomly separated to the external space.

The reciprocating means of the reciprocating body of the present invention takes a predetermined link mechanism method, but is not necessarily limited to such a method, and if the reciprocating motion is possible, for example, a stationary motor and two racks are disposed on both sides of one pinion for rotational motion. It is possible to adopt a movement switching means for converting the motor into a linear motion, or in the case of a large-scale washing machine for the operator, a linear motion mechanism (linear reciprocating device) may be adopted by using a pneumatic or hydraulic cylinder.

As described above, the present invention is surprisingly excellent invention despite the washing using the reciprocating body of a very simple structure.

As described above, the washing machine of the present invention uses the rotating body and the reciprocating body to wash the laundry by causing the washing water to shake in the tank, and thus the washing effect is a useful invention superior to the simple structure.
