Description

Nano Bubble Washing Machine

The present invention relates to a nanobubble washing machine equipped with a nanobubble generating device that generates microbubbles in cold water and hot water supplied from the outside and supplies them, thereby improving the washing efficiency in the washing machine body.

In general, nanobubbles are 'ultra-fine bubbles' that cannot be seen with the naked eye, and are fine air particles smaller than 25㎛ in size of skin pores and 1/2,000 the size of regular bubbles. When they disappear, 1) they generate ultrasonic waves of 40KHz, 2) generate high sound pressure of 140dB, and 3) generate instantaneous high heat of 4,000 to 6,000 degrees.

That is, while normal bubbles rise in the water and burst at the surface, nanobubbles shrink under pressure underwater, generate various energies, and then disappear.

These nanobubbles are ultra-small bubbles that are mainly formed when water and air are violently rotated.

Nanobubbles of this type are being utilized in various fields due to their physical and chemical properties such as “gas dissolution effect, self-pressurization effect, and electrification effect,” and recently, they are being used in various aquaculture and hydroponics especially in the fisheries and agriculture fields, and in the medical field for precision diagnosis, and in various fields for physical therapy, high-purity water treatment, and environmental devices.

That is, its fields of application are wide ranging from hot spring bathing to cancer diagnosis, and it is known to regenerate the skin and have excellent sterilization effects. Recently, devices applied to washing machines are being proposed to increase the washing efficiency of laundry.

Typically, washing machines are designed to automatically wash and rinse laundry by providing impact from the flow of water to the laundry.

These washing machines can be classified into a vortex type, an agitator type, and a drum type according to the washing method; the vortex type washing machine has a pulsator provided at the bottom of the washing tub, and can wash, rinse, and spin-dry the laundry in the washing tub using the rotational force of the pulsator. The agitator type washing machine has a similar appearance to the vortex type washing machine, includes an agitator bar provided in the washing tub, and is configured to reduce damage to the laundry due to entanglement; the drum type washing machine has a door installed at the front of the washing machine, and is configured to wash the laundry using a relatively small amount of washing water.

Meanwhile, recently, a washing machine including a bubble generating device that provides bubbles to the washing tub has been proposed to increase washing efficiency.

That is, when bubbles generated from the bubble generator are injected into the washing tub, the bubbles burst upon contact with the laundry and impact the laundry, so that contaminants on the laundry can be effectively removed.

Korean Patent Application No. 10-2011-0013168 (Title: Bubble generator and washing machine having the same/2011.02.15.), as announced in the official gazette, describes a washing machine including a tank containing wash water, a bubble generator that generates bubbles and supplies them to the tank, a pump that sucks wash water from the tank and supplies it to the bubble generator, and a connecting pipe having one end connected to the bubble generator and the other end positioned higher than the wash water level in the tank, wherein the bubble generator selectively forms either a bubble generating path for generating bubbles and supplying them to the tank, or a circulation path for guiding wash water to the tank through the connecting pipe.

Meanwhile, Korean Patent Application No. 10-2013-0161970 (Title: Washing machine including microbubble generating unit/2013.12.24.), as announced in the official gazette, describes a washing machine including a washing machine body including a washing unit capable of washing laundry; and a microbubble generating unit which generates microbubbles and supplies them to the washing unit, wherein the microbubble generating unit includes: a circulation driving unit which receives washing water from the washing unit and pressurizes the washing water at a high pressure; an air supply unit which supplies air; a mixing unit which is connected to the circulation driving unit and the air supply unit and mixes the washing water and the air; and a slit unit through which the washing water and the air mixed in the mixing unit pass and form the microbubbles.

The present embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer explanation. It should be noted that in each drawing, the same parts are sometimes drawn with the same reference numerals. Detailed descriptions of well-known functions and configurations that are judged to unnecessarily obscure the gist of the present invention are omitted.

FIGS. 1 to 9 are drawings showing a nanobubble washing machine (1) according to one embodiment of the present invention. The nanobubble washing machine (1) according to the present embodiment is suitably applied to wash laundry in a washing space (A) of a washing body (2) by receiving washing water (cold water and hot water) through a washing water supply pipe (31) comprising a cold water pipe through which tap water is directly supplied and a hot water pipe through which tap water is supplied via a heat exchanger (not shown) in general households and laundries.

The nanobubble washing machine (1) according to this embodiment comprises a washing body (2) having an opening that can be opened and closed internally and externally, a washing space (A) for receiving laundry is formed internally, and laundry is washed using supplied washing water; a supply pipe (33) connected to a washing water supply pipe (31) for supplying washing water from the outside to the washing space (A) and supplying the supplied washing water to the washing space (A); and an opening/closing valve (32) provided in the washing body (2) and provided in the washing water supply pipe (31) for selectively opening and closing the supply of washing water.

That is, by controlling the opening/closing valve (32) provided in the washing water supply pipe (31), washing water is supplied to the washing space (A) of the washing body (2) to wash the laundry.

The nanobubble washing machine (1) according to the present embodiment, which is constructed in this manner, includes a bubble generating device (100) which is provided in the washing body (2) and is arranged between the washing water supply pipe (31) and the supply pipe (33), and which receives washing water by operating the opening/closing valve (32), mixes it with air, and forms a dissolution pressure to generate nanobubbles.

That is, air is dissolved in tap water supplied through the washing water supply pipe (31) via the bubble generator (100) to generate nanobubbles, which are then supplied to the washing space (A) via the supply pipe (33).

Accordingly, the washing efficiency of laundry using nanobubbles in the washing space (A) is maximized.

The washing machine body (2) as described above may include a support device (21) formed as a 'frame structure' in the shape of a 'frame' having a facility space inside, and a washing tub (23) formed inside the washing space, which receives rotational power generated by a washing motor (22) driven by the control of a control means (91) that is supported so as to be able to rotate inside the support device (21) and controls by receiving power from a power supply unit (92).

That is, the washing tub (23) can be fixedly supported so as to be able to rotate through the support equipment (21).

In addition, a washing housing (24) that is sealed to the outside is provided on the outside of the support equipment (21) to protect the support equipment (21) and the washing tub (23) inside, and can also form a decorative aesthetic.

In the nanobubble washing machine (1) according to the present embodiment, which is configured as described above, the bubble generating device (100) is arranged in a space inside the support equipment (21) on which the washing machine main body (2) is supported; the opening/closing valve (32) is opened/closed by the control of the control means (91); and the washing water supply pipe (31) is installed so as to penetrate the inside and outside of the washing housing (24) that is sealed to the outside on the outside of the support equipment (21).

That is, since the bubble generating device (100) is installed in the support equipment (21) in a closed state with respect to the outside by the washing housing (24), the decorative aesthetic is not impaired.

In addition, since the above-mentioned opening/closing valve (32) is opened/closed by the control of the above-mentioned control means (91) that controls and drives the above-mentioned washing motor (22), washing water is stably supplied during the set washing process, and thus the washing work is stably performed.

In addition, since the washing water supply pipe (31) is exposed to the outside through the washing housing (24), domestic water and hot water are stably supplied from the outside.

Additionally, usability is improved through structural simplification and miniaturization.

In the nanobubble washing machine (1) according to the present embodiment, which is constructed in this manner, the bubble generating device (100) may include a dissolution body (4) in which the inlet (41) connected to the washing water supply pipe (31) is arranged on the outer surface, the outlet of the inlet (41) is arranged on the upper surface so that washing water is supplied from the outside and discharged to the upper surface, and the inlet of the discharge port (42) is arranged on the upper surface, the outlet of the discharge port (42) is arranged on the outer surface so that the washing water is discharged; and a dissolution tank (5) which is assembled while the open lower part is fastened to the upper part of the dissolution body (4) and has a dissolution space (B) inside which a dissolution pressure is formed for washing water supplied through the outlet of the inlet (41).

That is, the washing water is supplied from the inlet (41) formed on the outer side of the dissolution body (4) and supplied to the dissolution space (B) arranged above it, then dissolved in the dissolution space (B) to form nanobubbles, and then discharged through the outlet (42) formed on the outer side of the dissolution body (4) to be supplied to the supply pipe (33).

At this time, the melting space (B) can be formed inside the melting tank (5) on the upper part of the melting body (4).

Accordingly, simplification and miniaturization of the overall structure can be easily achieved.

Meanwhile, the bubble generating device (100) above may include a spray pipe (6) which is provided at the outlet of the inlet (41) formed on the upper surface of the melting body (4) and has a vertical length and a conveying pipe inside which the washing water is conveyed, so as to spray the washing water toward the upper portion of the melting tank (5) and cause it to collide with the upper bottom surface of the melting tank (5), thereby applying a collision load and a collision pressure to the washing water.

That is, when the washing water supplied to the dissolution space (B) through the outlet of the inlet (41) passes through the injection pipe (6) and collides with the upper inner surface of the dissolution tank (5) forming the dissolution space (B), collision pressure is applied, thereby promoting nanobubble formation.

In the above, the melting tank (5) may be provided with an air inlet one-way check valve (7) that opens when the water pressure in the melting space (B) is low and closes when it is high, so that an air inlet pipe (71) that selectively supplies external air may be provided.

That is, when the washing water is not filled in the above-mentioned dissolution space (B), external air is introduced through the air inlet pipe (71) and filled, and when the washing water is filled later, the air is dissolved and nanobubbles may be generated.

Accordingly, it is possible to supply air stably even without a separate air supply means.

In the nanobubble washing machine (1) according to the present embodiment, which is constructed in this manner, a drainage pipe (8) equipped with a drainage one-way check valve (81) that is positioned below the washing water supply pipe (31) and the supply pipe (33) and opens when the water pressure in the space where the washing water moves is low and closes when it is high can be connected to the outlet of the discharge port (42).

That is, when the washing water is not in use, the washing water remaining in the dissolution space (B) can be easily drained through the drain pipe (8) to lower the water pressure in the dissolution space (B), thereby allowing external air to be stably filled through the air inlet pipe (71).

In the above, the drainage section of the drainage pipe (8) is connected to the drainage pipe (25) spatially connected to the washing space (A) of the washing body (2), so that the drained washing water can be stably drained to the outside through the drainage pipe (25); this can be suitably applied according to the user's choice.

In the nanobubble washing machine (1) according to the present embodiment as described above, the supply pipe (33) may be configured such that the tip is connected to the discharge port (42) of the bubble generating device (100) and the end penetrates the washing body (2) to supply to the washing space (A).

That is, washing water containing nanobubbles can be supplied to the washing body (2) while being sprayed from the dissolution body (4) of the bubble generating device (100) through the end of the supply pipe (33) to perform the washing operation.

At the end of the supply pipe (33) above, a discharge head (34) equipped with a discharge nozzle for discharging and spraying washing water into the washing space (B) can be connected.

That is, the washing water supplied from the supply pipe (33) can be discharged by spraying it through the discharge head (34).

In the above, the discharge head (34) may be provided with a collision plate member (35) that is arranged in front of the discharge nozzle with a gap so that the sprayed washing water collides with it and spreads.

That is, when the washing water containing bubbles sprayed from the discharge nozzle collides with the collision plate member (35), collision pressure is applied, and air is dissolved and re-formed, which can improve the bubble quality.

Accordingly, washing efficiency can be increased.

The operation and effect of the nanobubble washing machine (1) according to this embodiment are described in detail as follows.

When washing laundry using the nanobubble washing machine (1) according to this embodiment, first, open the opening of the washing space (A) of the washing body (2) and put the laundry to be washed in, and close the opening of the washing space (A) to seal it from the outside.

And when the data set in the control means (91) is manipulated and driven through a separate operating means (not shown), the opening/closing valve (32) opens, and the washing water supplied through the washing water supply pipe (31) is transformed into nanobubbles while passing through the bubble generating device (100), and then is supplied to the washing space (A) through the discharge head (34) via the supply pipe (33) and filled.

When the washing water is filled to the level set in the washing space (A) in this way, the opening/closing valve (32) is closed according to the setting data set in the control means (91), the supply of washing water is stopped, and the washing motor (22) is driven and the washing tub (23) rotates, washing or rinsing the laundry, respectively, thereby performing the washing work of the laundry.

Meanwhile, when the above-mentioned opening/closing valve (32) is closed, the washing water remaining in the dissolution space (B) is drained through the drain pipe (8), thereby lowering the water pressure in the dissolution space (B), and external air is stably filled through the air inlet pipe (71).

Accordingly, when the opening/closing valve (32) is opened later, the air is stably dissolved in the dissolution space (B).

FIG. 10 is a drawing showing a nanobubble washing machine (1) according to one embodiment of the present invention. The nanobubble washing machine (1) according to the present embodiment may be equipped with two sets of bubble generating devices (100) each formed by a hot water pipe (31a) for supplying hot water and a cold water pipe (31b) for supplying cold water, respectively, in the washing water supply pipe (31).

That is, a pair of the above bubble generating devices (100) can selectively supply hot water, cold water, and hot-cold mixed water (a state in which hot water and cold water are mixed) to the above supply pipe (33).

Accordingly, customized washing operations can be performed for each type of laundry, thereby improving the quality of use.

As described above, the nanobubble washing machine (1) according to the present embodiment is characterized by a technical configuration in which, while supplying washing water to the washing space (A) of the washing body (2) by controlling the opening/closing valve (32) arranged between the washing water supply pipe (31) and the supply pipe (33), air is dissolved through the bubble generating device (100) to generate nanobubbles and supply them to the washing space (A).
