Description

Vibration Washing Machine {Vibration type Washing machine}

The present invention relates to a vibration washing machine, and more particularly, by vibrating the tub itself by using the driving principle of the linear motor, the vibration causes a resonance phenomenon between the washing water, detergent, and laundry. The present invention relates to a vibration washer that is smoothly washed with a positive amount of wash water.

In general, the pulsator washing machine used is to wash the laundry while the laundry (water) and washing water (washing water) and detergent are put together and the pulsator or inner tub is rotated according to the signal generated from the controller.

Referring to the configuration of the pulsator washing machine for reference as follows.

That is, as shown in FIG. 1, the pulsator washing machine includes an outer case 1, an outer tub 2 installed to be supported in the outer casing 1, and an inner rotatably installed in the outer tub 2. Tub 3 and a pulsator 4 rotatably installed on the inner bottom surface of the inner tub 3 to remove contaminants by applying mechanical agitation to the laundry, and necessary for rotating the pulsator 4. The motor 5 which generates a driving force is basically comprised.

In addition, a clutch (6) for receiving the driving force of the motor (5) by the V-belt (9) and selectively rotating the inner tub (3) and the pulsator (4), and the shaft on the clutch (6) Combined with a dehydration shaft 11 to transmit the rotational force to the inner tub (3), and the washing shaft to be installed concentrically in the dehydration shaft 11 to transmit the rotational force of the motor only to the pulsator (4) during washing, It is composed.

In addition, during dehydration, the washing shaft 10 is coupled to the dehydrating shaft 11 to rotate the inner tub 3 and the pulsator 4 at the same speed, and is fixed to the lower end of the washing shaft 10. A clutch pulley (8) which receives the rotational force of the motor (5) through the belt (9) and decelerates first, and is axially coupled to the motor (5) to the clutch pulley (8) through the V-belt (9). It is configured to include a motor pulley (7) for transmitting a rotational force.

In addition, the water supply valve 13 is installed on one side of the upper case of the outer case 1 and opened and closed to supply the washing water, and the lower portion of the outer tub 2 is washed and rinsed through the drain hose 15. It is configured to include a drain valve 14 for opening and closing to drain the wash water used in the outside of the outer case (1).

In addition, the upper portion of the inner tub (3) is installed on the balancer (12) of the hollow ring shape to reduce the vibration of the upper portion of the inner tub (3) due to the bias of the laundry, and the upper portion of the outer case (1) And a top cover 17 in which parts such as a controller 19 and a water supply valve 13 are embedded.

In addition, the door 20 is installed in the upper portion of the outer case 1 so as to be opened and closed, the base 18 is installed in the lower portion of the outer case 1 to support the components, and in the inner tub (3) It consists of a plurality of dampers (16) to prevent the vibration and noise generated because the inner tub (3) and the outer tub (2) eccentrically rotate due to the bias of the laundry contained therein.

The pulsator washing machine configured as described above puts laundry into the inner tub 3, closes the door 20, and selects and operates a mode provided on the controller 19. The washing water is supplied through the water supply valve 13. The water is supplied and the rotational force by the driving force of the motor 5 is transmitted to the clutch 6 by the pulley 7 and the V-belt 9.

At this time, as the clutch 6 transmits the driving force of the motor 5 only to the pulsator 4 in a decelerated state, the clutch 6 rotates the laundry in the inner tub 3 while rotating only the pulsator 4. Since the water flow is generated, the laundry is washed by the rotational force of the pulsator 4 and the frictional force between the inner wall of the inner tub 2 and the decomposition force of the detergent.

In addition, during dehydration, the clutch 6 receives the driving force of the motor 5 transmitted through the V-belt 9 in one direction while draining the washing water in the inner tub 3, and the inner tub 3 is rotated. In addition, the washing shaft 10 and the dehydration shaft 11 are coupled to each other while being delivered in a first decelerated state to the pulsator 4 and the inner tub 3 and the pulsator rotate at the same time at a high speed.

Accordingly, while the laundry in the inner tub 3 is pushed outward by the centrifugal force, the moisture contained in the laundry comes out. At this time, the drain valve 14 opens, so that the water discharged from the laundry drains the drain hose 15. Through the drainage to the outside of the case (1) through which the dehydration is completed.

The above described pulsator washing machine is the inner tub is eccentrically rotated, the eccentric rotation when the laundry is twisted at the time of washing, when the dewatering stroke is started when the drainage stroke is not released when draining stroke Noise is generated by the inner tub.

In addition, the strong water flow generated in the inner tub easily damages laundry made of delicate fibers such as underwear, and the laundry is dewatered by centrifugal rotation of the inner tub even at the time of dehydration. The laundry is also damaged by tangling and kinks between the laundry.

In addition, since the washing machine washes by using friction between the washing water and the laundry generated by the rotation, even when washing a small amount of laundry, a considerable amount of washing water is basically consumed, which wastes water.

In addition, the washing machine has a fundamental problem that the consumption of water is inevitably larger than washing by hand because the washing water is watered and drained several times in the process of performing a series of operations such as washing / rinsing / dehydration.

Therefore, it is not suitable for processing a small amount of laundry in a washing machine which is large in capacity as of the present.

In addition, the conventional washing machine has a problem in that the overall structure is complicated and not only the productivity is lowered, but also precision parts such as a clutch are used, so that the manufacturing cost of the washing machine is increased, and defects such as the clutch may cause inconvenience to the consumer.

The present invention has been made to solve the problems of the prior art, to prevent damage to the laundry occurs during washing, freely controlling the water level in proportion to the amount of the laundry and at the same time after draining without a separate dehydration process The aim is to protect the interests of consumers by developing a washing machine that immediately dries laundry to reduce the waste of excess water.

In addition, the objective of the present invention is to improve productivity and reduce manufacturing costs by developing a simple washing machine in which a precision component, such as a clutch, is removed.

In this case, the linear motor is installed on the outer circumferential surface of the tub 204 and an armature 205 made of a permanent magnet to vibrate the tub 204, and an armature to apply an electromagnetic force to the armature 205 to cause vibration. And a stator 206 provided on an inner surface of the outer case 200 facing the outside. The drive control unit for controlling vibration of the armature 205 is further provided, and the drive control unit has a tub 204 as shown in FIG. And a frequency command unit 300 for determining a frequency to be applied to the linear motor according to the level of the wash water being filled in the tub so that resonance occurs between the polyphase media in the multi-phase medium. And an amplifying command unit 301 for converting the generated frequency into an amplitude suitable for driving the linear motor, and a driving unit 306 for driving the linear motor at a frequency passing through the amplifying command unit. The unit 300 includes a frequency commander 302 for determining an appropriate frequency for the level of wash water received from the water level sensor, and a voltage controlled generator (VOC) for generating a frequency by the signal of the frequency commander. oscillator 303, and the amplification command unit includes an amplifier 304 and an amplification command unit 304 for controlling the amplifier, and the driving unit 306 includes an inverter.

In the vibration washing machine, a plurality of elastic bodies 213 are installed below the tub 204 to expand the vertical movement amplitude of the tub 204, and a plurality of dampers that hold the tub 204 from side to side during vibration. In addition, the vibration washing machine is installed on the inner surface of the outer case 200, the magnetron 208 for generating a microwave, and for cooling the high heat generated during the operation of the magnetron 208. Cooling fan 210, the fan motor 209 for rotating the cooling fan 210, the coaxial cable 211 to guide the microwave generated in the magnetron, and the microwave guided by the coaxial cable Drying means comprising a guide means for guiding into the tub 204 are installed.

The drying means further includes a reflecting plate 212 that diffuses the microwaves guided through the coaxial cable 211 in the tub 204.

In addition, the guide means is a tub cover 202 installed on the top of the tub so as to be opened and closed, a connecting portion 218 connected to the tub cover and the drying means to guide the microwaves into the tub, and the micro-entries into the connecting portion 218 It is configured to include a plurality of entrance holes 203 installed below the tub cover 202 so that the wave is incident to the entire inside of the tub.

In addition, the water supply valve 215 is installed on the upper side of the outer case 200, such as a conventional washing machine, and opened and closed to supply necessary washing water according to a user's selection through a water supply hose (not shown), and the tub. It is configured to include a drain valve 216 is installed in the lower portion of the 204 is opened and closed to drain the wash water used for washing through the drain hose 217 to the outside of the outer case 200.

Referring to the operation of the present invention according to the embodiment configured as described above are as follows.

First, the laundry is put into the tub 204, and the washing water to the extent that the laundry is locked is supplied to the tub 204 through the water supply valve 215, and then the water supply valve is closed. The water level sensor (not shown) is installed so that the washing water is appropriately supplied according to the amount of the laundry, and also transmits information about the washing water level to the frequency command unit 300 of the drive control unit. In 300, the resonance frequency is determined according to the data on the wash water level, and the driving unit 306 drives the linear motor at the frequency amplified by the amplifying command unit 301 according to the determined frequency.

Thus, the vibration control signal from the control unit 214 is sent to the stator 206, the electromagnetic force is generated in the stator 206 by the vibration control signal transmitted to the coil, the armature (the electromagnetic force is a permanent magnet) When applied to 205, the armature 205 moves up and down by the driving principle of a linear motor that directly converts electromagnetic force into linear mechanical energy.

That is, since the direction of the electromagnetic force is quickly converted in accordance with the vibration control signal from the drive controller 214, the tub 204 provided with the armature 205 driven by the electromagnetic force also has a high frequency by the conversion. .

When the vibration force generated by vibrating the tub 204 is applied to the wash water in the tub 204, the micro air generated at this time is caused by a resonance phenomenon in the polyphase medium including the wash water, detergent, laundry, and air layer. The mechanical action of the droplet cavitation or nonlinear vibration and the chemical action of the detergent combine to perform the washing.

When the washing and rinsing action is completed by the vibration, the drain valve 216 is opened to drain the wash water contained in the tub 204 to the outside of the outer case 200.

After the drain, the microwave is oscillated from the magnetron 208 installed on the upper inner circumferential surface of the outer case 200 and is sent to the tub cover 202 through the coaxial cable 211 used as the waveguide.

And, the microwaves sent to the tub cover 202 is spread into the tub 204 by the entrance hole 203 formed in the tub cover 202, the microwave is a reflection plate installed in the tub (204) 212) once again spread through the laundry.

In addition, when the reflected microwaves enter the laundry with moisture, moisture inside the laundry serves as a heating element by the microwave, and the laundry is dried by the heat generated at this time, and the sterilization action is also performed. .

On the other hand, instead of the drying means using the microwave may be provided a separate drying means for drying the laundry using far infrared rays.

That is, an electric heater that emits far infrared rays is installed in place of the magnetron that generates the microwaves, and the laundry is dried by inducing the far infrared rays into the tub. At this time, the water discharged from the laundry produces a moisture discharge duct (not shown). As it is understood by those skilled in the art that the discharge through the water discharge structure will be omitted. Of course, the drain valve may be opened to discharge moisture through the drain hose.

As described above, the present invention requires only one tub, and does not use a clutch, which is a precision component used in a conventional washing machine, because washing is performed by applying vibration directly to the tub containing laundry.

Therefore, the structure of the washing machine can be simplified, thereby improving productivity and reducing the cost of the product.

In addition, the present invention is because the vibration generated by the tub is applied to the wash water only the amount of water that can cause a resonance phenomenon between the wash water and the laundry and detergent is reduced, compared to the conventional washing machine, the amount of water consumed is reduced, the laundry Since the water level of the washing water can be properly adjusted in proportion to the amount, it is possible to reduce the waste of water consumed more than necessary when washing a small amount of laundry.

In addition, since washing is performed by the vibration, the laundry is twisted and entangled like a conventional washing machine, and friction with the inner wall of the tub does not occur, thereby causing the laundry to be damaged.

In addition, since the present invention uses a microwave as a drying means, it is possible to immediately dry the laundry in the tub after draining without a separate dehydration process.

Through this, it is possible to eliminate the labor and time waste of the customer to dry the laundry separately, and because the nature of the microwave laundry is sterilized naturally can give additional benefits to the consumer.
