The present invention relates to a washing machine,

More specifically, a bubble generating unit and an ozone generating unit are installed in a washing machine to selectively generate bubbles during washing and rinsing of laundry to improve washing efficiency of the laundry or to generate ozone to a washing machine capable of sterilizing and bleaching laundry. It is about.

In general, a washing machine can program washing, rinsing, draining, and dehydration in the microcomputer in advance in the washing machine control unit, so that the user can selectively control the washing operation. .

Such a fully automatic washing machine is generally as shown in FIG. 1, and reference numeral 100 in the drawing denotes a washing machine body.

As shown in the figure, the main tank 100 is fixedly installed in the tank 200 for storing a certain amount of washing water required for washing.

In the water tank 200, a washing tank 300 having a pulsator 400 is provided, and a power driving unit 500 for transmitting power required for washing is provided at an outer lower portion of the water tank 200.

The power driving unit 500 is provided at the outer lower portion of the water tank 200 to the driving motor 510 for generating power, and the power source transmission unit 530 for controlling the power of the driving motor 510 through the belt 520. It is composed.

Therefore, when the washing machine is put in the washing tank 300 and the washing machine is operated during the washing operation, the driving motor 510 is operated by the control program or the user's setting data, and the driving motor 510 is driven by the belt 520. The transfer unit 530 is transmitted.

The power division transmission unit 530 transmits the power of the driving motor 510 transmitted through the pulley 520 according to washing or dehydration to the pulsator 400 or the washing tank 300.

That is, during washing, the power division transmitting unit 530 operates so that the power of the power driving unit 500 is transmitted to the pulsator 400, and the initial driving unit 500 rotates the pulsator 400 left and right at the beginning of washing. The washing amount is measured.

When the washing amount is measured, the washing water according to the washing amount is supplied by the operation of a water supply side (not shown), and when the washing water is supplied according to the washing amount, the power driving unit 500 rotates the pulsator 400 left and right, and the pulsator ( Washing is performed by the friction of the laundry and the washing water and the pulsator 400 and the washing tub 300 generated when the left and right rotation of the 400.

When dewatering, the power division transmission unit 530 transmits the power of the driving motor 510 to the washing tub 300 to rotate the washing tub 300 at high speed to perform the dehydrating stroke.

Of course, the drainage stroke is performed before the dehydration stroke.

Due to this operation principle, a general washing machine is repeatedly performed at least once or several times according to a control program or user's setting data and laundry for water supply, washing, draining, dehydration, and rinsing stroke.

However, the general washing machine having such a configuration is remarkable because the washing is performed only by the friction force between the laundry and the washing water and the pulsator 400 and the washing tub 300 generated when the pulsator 400 rotates left and right as described above. I did not expect the washing efficiency.

Therefore, a washing machine equipped with a bubble generating device capable of increasing the washing effect of the laundry by bubbles by dispersing bubbles in the water stream during the washing administration of the Applicant Announcement No. 90-11015, which was previously proposed by the applicant, and No. 92- In the washing administration of No. 8480, a washing machine equipped with an ozone generating device for washing laundry by disinfecting, disinfecting, bleaching and deodorizing laundry has been proposed.

That is, in the case of the former, the air inlet tube is integrally formed to protrude upward from the bottom plate at a predetermined position on the bottom of the washing tank, the air supply hose is connected to the cap nut at the lower part, and the cap having the air bubble hole is perforated at the upper part. Is covered with a screw and installed inside the shielding valve which is downwardly supported by a spring to open and close the air inlet pipe as the air is blocked, so that it is generated by the air supplied from the compressor provided in the lower side of the washing machine. By supplying air bubbles to the water flow inside the dehydration tank vortexed through the pulsator through the air holes, the pressure and pressure around the air bubbles are generated by the shock and vibration generated when the air bubbles are broken, and the contaminants adhered to the laundry are washed.

In the latter case, the water supply valve is mounted on the fixed cover inside the washing machine, and the water supply valve hose is connected to one side to connect the ozone generator combined with the screw through the packing between the upper case and the lower case. Voltage oscillator, power supply unit, ozone generator, water supply valve operation unit, power detection unit, control unit, water level detection unit, which connects one side and water supply hose to the water supply control unit so that ozone generator operates only when water supply and water level change. The ozone generation safety circuit of the display unit was configured to be a combination, which was an improvement of the applicant's another previously filed patent application No. 90-10581.

However, these bubble generators and ozone generators have different washing efficiencies such as washing, sterilizing, and bleaching the laundry, respectively, while having a separate cover for installing a separate compressor and ozone generator must be installed in the washing machine. Not only did it take up a lot of space, but it also led to other problems, such as reduced productivity due to the difficulty of the assembly process.

Therefore, it has become a factor contrary to the simplification of the lighter and slimmer parts of the product, which is a problem to be solved by the washing machine.

Therefore, the present invention brings about a lighter, slimmer, and simplified parts of the washing machine, and increases the washing power of the laundry, sterilizes the laundry, and rinses under the bleaching process by generating bubbles and ozone in the washing water selectively during the washing operation of the laundry. The purpose is to provide a washing machine that can be.
