Description

Micro bubble washing machine

The present invention relates to a microbubble type washing machine, and more particularly, to a washing machine of a microbubble type which improves washing time as well as washing power by adding a predetermined device to shorten the time for boiling and drying water in a fully automatic washing machine for boiling and drying laundry. It is about.

Referring to FIG. 2, in general, a washing machine has a main component such as a washing tank 12, a dewatering tank 13, and an outlet water pipe 18 connected to each other, and the motor 15 and the motor 15 are connected to each other. And a clutch motor composed of a gear clutch 14 driven by a belt as a power source.

When the user puts laundry into the washing tank 12 and operates a switch, washing water and detergent are added to the washing, and the gear clutch 14 and the motor 15 rotate the washing tank 12 to wash the water from the washing tank to dehydration. This is done sequentially.

On the other hand, in recent years, a variety of devices have appeared in accordance with the trend of increasing the size and high quality of home appliances, the bottom of the washing tank 12 may have a pulsator 16 device having a wing shape rotated, the washing tank 12 In some cases, a shower nozzle having a water spray nozzle function (not shown) may be installed in the upper portion and the washing water may be ejected through a separate shower water pipe.

The former mainly serves to increase the washing power, and the latter mainly serves to improve the rinsing power.

In addition, the recent air bubble generation washing machine to improve the washing power to accelerate the saponification of the water by intermittently introducing air bubbles during washing using a diaphragm pump (not shown).

Further, in the washing machine having the pulsator 16, the washing water flowing out through a myriad of holes formed in the wall surface of the washing tank 12 is washed along the dewatering channel formed between the washing tank 12 and the dewatering tank 13. In some cases, the circulator 16 may be circulated back to the washing tank 12 through the bottom or the pulsator 16, and is mainly used to prevent tangling of laundry in the washing process.

In addition, various means for increasing the washing power have been introduced, but rather than an effort to improve the saponification action between the laundry and the wash water has been a result of increasing the damage to the laundry by providing a direct physical force to the laundry.

For example, when installing a laundry rod (not shown) that moves up and down in the center of the washing tank 12, the washing force is slightly increased, but there is a fear that the laundry is damaged due to the impact caused by the laundry rod.

On the other hand, the heater 17 may be installed in the waterway between the washing tank 12 and the dehydration tank 13 in order to improve washing power without physically damaging the laundry. When the washing water is heated by the heater 17, the saponification effect is promoted, and the laundry is boiled to increase the cleanliness.

However, in the method of applying the heater 17, since it takes a relatively long time to increase the temperature of the washing water at room temperature to the boiling point, the washing time is increased and power consumption is also increased.

In addition, there is a problem that care must be taken when the hot wash water is drained to the discharge water pipe 18, and the heat resistance of the drain cutoff valve 19 is also taken into consideration.

Accordingly, the present invention provides a microcomputer that improves washing time as well as washing power by adding a predetermined device for shortening the time for boiling and drying water in a fully automatic washing machine for boiling and drying laundry in order to propose a means for solving the above problems. It is an object of the present invention to provide a bubble type washing machine.

EXAMPLE

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 shows a thermodynamic state diagram of water.

As the temperature and pressure conditions of water exist in the three states of liquid, gas and solid, the transition between such states occurs, and the line shown shows the point where the transition between liquid, gas and solid occurs.

For example, the point A on the ship is a boiling point that changes from a liquid state to a gaseous state and usually indicates a state of 100 ° C. under 1 atmosphere. If the pressure is lowered from 1 atmosphere to a predetermined pressure P ', the previous evaporation point A moves to a new evaporation point A' along the ship's line, and the temperature T 'becomes lower than 100 ° C. In other words, when the pressure is lowered, the water becomes steam even at a temperature lower than 100 ° C.

Therefore, using this principle, the washing machine according to the present invention adds a device for lowering the pressure inside the washing tank and the dehydration tank.

2 is a block diagram showing the arrangement of the main part of the washing machine according to the present invention.

The washing machine 12 having the pulsator 16 in the dehydration tank 13 having the heater 17 is rotated by the motor 15, and the washing machine performs washing operation. The main configuration is a pump 22, an air shutoff valve 23, a pressure switch 24, a control panel 26 and the like.

The main components of the washing tank 12, the dewatering tank 13, the pulsator 16, the discharge water pipe 18, and the like are driven by the motor 15 and the gear clutch 14 in the same manner as before.

At this time, the door 11 according to the present invention is mounted on the washing tank 12 and the dewatering tank 13 through the packing 25 to be hermetically, and includes a fixing part and an opening part.

Conventional doors are required to have a degree of airtightness to prevent the outflow of the wash water, but in the present invention to block the inflow of air into the washing tank 12 in which a predetermined vacuum pressure is formed. Half of the door 11 is a fixed portion that can not be opened by the user and the other half is an opening that can be opened by hinged to the fixed portion, the packing 25 is installed over the entire portion where airtightness is required. The user can put or take the laundry into the opening.

In addition, one end of the air pipe 21 of the present invention is connected to the fixed portion of the door 11 is guided to the lower part of the washing machine, the other end of the air pipe 21 by connecting a vacuum pump 22 to a predetermined To form pneumatics.

There are many types of vacuum pumps 22, such as a reciprocating piston type and an eccentric vane type, depending on the principle of operation. The vacuum pump 22 is selected in consideration of the required degree of vacuum pressure or the airtightness of the door 11, and the like.

In addition, the air shutoff valve 23 of the present invention is connected to the airtight pipe on the air pipe 21, and opens and closes the air flow path by electrical pressure.

The air shutoff valve 23 is a kind of solenoid-driven opening / closing valve, which normally closes the flow path and opens the flow path only when the air in the washing tank 12 and the dehydration tank 13 is discharged.

In addition, the pressure switch 24 of the present invention is mounted to the fixed portion of the door 11, and generates a signal when the washing tank 12 and the dehydration tank 13 inside have a predetermined vacuum pressure.

The pressure switch 24 may use a method using heat conduction or a method using ions. The pressure switch 24 may be a type in which an internal contact is closed at a pressure slightly lower than a vacuum pressure that is actually achievable on a system of a washing machine.

In addition, according to the present invention, a function of operating the heater 17 while opening the air shutoff valve 23 and operating the vacuum pump 22 until there is a predetermined input from the pressure switch 24 is added. Use the control panel 26 provided with.

Although not shown in the drawing, the control panel 26 is provided with a display for displaying a switch and an operation state for a normal external input, and in particular a vacuum pressure is formed inside the washing machine of the present invention. Equipped.

Accordingly, the control panel 26 indicates the state while the vacuum pressure is applied to the interior of the washing tank 12 and the dehydration tank 13, and when the washing is completed, briefly turn off the air shutoff valve 23. To release the vacuum pressure inside the washing tank 12 and the dehydrating tank 13.

The release of the vacuum pressure takes into account that it is difficult to open the door 11 while the vacuum pressure is applied to the washing tank 12 and the dehydrating tank 13.

The indicator of the operation panel 20 continues to light while the predetermined vacuum pressure is formed in the washing tank 12 and the dehydrating tank 13. The operation of the vacuum pressure is detected by the operation panel 20 periodically received from the pressure switch 24.

With such a configuration, the washing water during washing is boiled at 100 ° C. or lower, and finer bubbles (aka micro bubbles) are formed by the interlocking operation with the pulsator 16, so that the washing power is improved.

In addition, since the wash water boils below 100 ° C., not only can it perform a quick washing operation and a drying operation with low power consumption, but also easily drains through the discharge water pipe 18.

On the other hand, the higher the vacuum inside the dehydration tank 13, the lower the boiling point of the wash water, the greater the effect according to the present invention, but the pressure difference between the inner and outer surfaces of the dehydration tank 13 is disadvantageous in terms of strength.

As described above, the microbubble washing machine of the present invention adds a decompression device to form a predetermined vacuum pressure in a fully automatic washing machine for boiling and drying laundry, thereby shortening the time for boiling and drying water, and of course, washing power by the microbubble. There is an effect to improve.

While the invention has been shown and described with reference to certain preferred embodiments, it will be understood that the invention can be variously modified and modified without departing from the spirit or scope of the invention as set forth in the claims below Those skilled in the art can easily know that.
