The automation of washing work, which was difficult to do with conventional machines, is an example, and many parts of daily life are improved through automated machine washing.

The cleaning device may be, for example, a combination of technologies such as an automatically operating nozzle, a vibrator, and a bubble generator. In particular, it is known that oily tableware or vegetables and fruits having complex surfaces can be effectively washed by using vibration induction by a vibrator and contact with bubbles (bubbles) in water by a bubble generator.

A bubble washer using a double bubble generator can be manufactured with a relatively simple structure, and its application range is also expanding. Since bubbles (bubbles) can be created by discharging air through holes in water, attempts have been made to increase the cleaning effect by bubbles by improving the structure (e.g., Korean Utility Model No. 20-2011-0000769). Etc).

However, for example, problems such as blind spots of bubbles generated in the washing machine and performance degradation of the bubble generator due to impurities are still insignificant. In particular, there was a problem in that it was difficult to provide bubbles without a blind spot inside a large washing container, and when the bubble generator was repeatedly used, there was a problem that the hole was clogged with debris and did not operate normally, but an appropriate alternative was not presented. there is.

However, the present embodiments are provided to support the present invention so that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, the present invention is only It is only defined by the claims. Like reference numerals designate like elements throughout the specification.

In this specification, a 'spiral shape' means a shape made by repeatedly winding one line from the outside to the inside, but does not mean only a shape in which all parts of the line are curved. For example, as illustrated in FIG. 2, the 'square spiral shape' may be a shape that winds inward while repeating a refracted section bent at a certain angle between straight sections.

Therefore, even if it has a partially straight section, it is included in the spiral shape of the present invention if the refracted section is repeated and the shape is wound as a whole.

Hereinafter, with reference to FIGS. 1 to 6, a bubble pipe for a bubble washer and a cleaning method thereof according to the present invention will be described in detail. However, after the bubble tube is first described in detail with reference to FIGS. 1 to 3 so that the description of the present invention is concise and clear, the cleaning method of the bubble tube will be described in detail with reference to FIGS. 4 to 6 based thereon. .

1 is a perspective view of a bubble tube for a bubble washer according to an embodiment of the present invention, and FIG. 2 is a plan view of the bubble tube of FIG. 1 .

1 and 2, the bubble pipe 1 (hereinafter referred to as bubble pipe) for a bubble washer according to the present invention has a body 10 in a planar spiral shape in which the body 10 is repeatedly wound from one end to the other end. is formed

This bubble pipe 1 has a structure in which it is repeatedly wound from the outside toward the center on a single plane (bottom surface (A) in FIG. 2).

Therefore, it is possible to fill a space on a flat surface (eg, a washing space on a floor surface) with bubbles without a substantial blind spot by a spiral structure in which bubbles (bubbles) are repeatedly wound when they are raised from the bubble pipe 1 . With the bubble tube 1 having a spiral structure, bubbles can be uniformly provided to every corner of the inner space of the washing tub.

In addition, a detachable stopper 13 is formed at the other end of the bubble pipe 1 located in the center of the spiral. When the detachable stopper 13 is separated, the other end is opened and air is discharged toward the center of the spiral. Therefore, if this process is performed in a drained state after washing, since dirt can be removed from the other end side only with air pressure, the cleaning of the bubble pipe 1 proceeds immediately after washing. In addition, since washing and the cleaning operation of the bubble pipe 1 are linked, the number of times of cleaning can be increased as much as desired, and the bubble pipe 1 can also be kept clean.

The bubble pipe 1 of the present invention is configured as follows. The bubble tube (1) is a bubble tube for a bubble washer that is disposed at the bottom of the washing tub of the bubble washer to generate bubbles for washing objects to be washed, and has a plurality of bubble generating holes (10a) perforated on the outer surface of the tube with an empty inside. A body 10 made of, an air inlet 11 formed at one end of the body 10 and communicating with the inner space of the body 10, formed at the other end of the body 10 and the inner space of the body 10 It includes a waste outlet 12 communicating with the waste outlet 12, and a detachable stopper 13 detachably coupled to the waste outlet 12 to seal the waste outlet, and the body 10 is disposed on the bottom surface of the washing tub (FIG. 2 and FIG. 4, A) It is characterized in that the other end of the body 10 is disposed inside the bottom surface than the one end by being refracted in a planar spiral shape that is repeatedly wound from the circumference toward the center.

In particular, in this embodiment, the planar spiral shape formed by the body 10 includes a rectangular planar spiral shape including a straight section in at least a portion thereof. Also, due to such a spiral shape, the body 10 may be overlapped with the bottom surface of the washing tub in a shape corresponding to that of the bottom surface.

A planar spiral shape means a shape in which spirals are arranged on one plane rather than a three-dimensional shape, and a square planar spiral shape means a spiral shape in which a straight line section and a refraction section are repeated while winding because a straight line section is included among plane spiral shapes. . The square planar spiral shape conforms to the shape of the body 10 shown in FIG. 2 .

Hereinafter, the configuration and operational effects of the present invention will be described in more detail based on such an embodiment of the present invention.

Referring to FIG. 1, the body 10 of the bubble pipe 1 is made of a tubular body with both ends open. Although shown as a cylindrical tubular body on the drawing, there is no need to be limited thereto and may be formed of a tubular body having a polygonal cross section such as a square tube. The body 10 may be formed of various types of tubes or pipes in which a fluid flow path is formed.

An air inlet 11 communicating with the inner space of the body 10 is formed at one end of the body 10, and a waste outlet 12 communicating with the inner space of the body 10 is formed at the other end of the body 10. is formed As shown in FIG. 1, the waste outlet 12 is sealed with a detachable stopper 13, but can be opened by separating the detachable stopper 13. The air inlet 11 and the waste outlet 12 communicate with each other through the inner space of the body 10.

A plurality of bubble generating holes 10a are perforated on the outer surface of the body 10 . The hole 10a for bubble generation is not necessarily limited thereto, but may be formed as a fine hole having a diameter of about 1 mm or less (preferably 0.8 mm or less), for example. The hole 10a for bubble generation may be formed through laser processing, and a plurality (eg, at least 100 or more) may be perforated in the body 10 .

When air is injected into the body 10 while the bubble tube 1 is held in the water, the holes 10a for generating bubbles discharge air and generate bubbles (refer to the enlarged view of FIG. 4). In order to increase the synergistic effect of bubbles and thus the effect of collision with the object to be cleaned, the hole 10a for bubble generation may be opened upward by gravity. The spacing, number, etc. of the bubble generating holes 10a may be adjusted as needed.

A detachable stopper 13 is coupled to the waste outlet 12. As described above, the detachable stopper 13 is detachably coupled to the waste outlet 12. The detachable stopper 13 is detachably coupled and seals the waste outlet 12 when coupled. Accordingly, substantial air leakage does not occur to the other end of the body 10 in the state shown in FIG. 1 .

The detachable stopper 13 may be particularly screwed together. For example, the detachable stopper 13 may include an insertion protrusion 131 inserted into the waste outlet 12 and having a screw thread 131a formed thereon. Corresponding threads (see 121a in FIG. 3 (b)) may be formed inside the waste outlet 12, and thus, by screwing between the insertion protrusion 131 and the waste outlet 12, the waste outlet 12 can be effectively sealed.

Although not shown, a sealing member made of, for example, an O-ring may be disposed between the detachable stopper 13 and the waste outlet 12 to enhance the sealing effect. Since the detachable stopper 13 is not pushed out by internal pressure or the like by screwing, it can maintain a sealed state without any problem even when the air pressure injected into the body 10 increases.

The body 10 of the bubble tube 1 is formed by bending in a planar spiral shape as shown in FIGS. 1 and 2 . As a result, one end where the air inlet 11 is formed is disposed on the outside, and the other end where the waste discharge port 12 is formed is disposed on the inside. Since the bubble tube 1 is used by being disposed at the bottom of the washing tub, the body 10 of the bubble tube 1 has a flat spiral shape that is repeatedly wound from the circumference to the center of the bottom surface of the washing tub (shown as A in FIG. 2). can be refracted into

In particular, as shown in each drawing, the body 10 may be formed in a rectangular planar spiral shape including a straight section in at least a portion thereof. As shown in FIG. 2, the body 10 of the bubble pipe 1 is bent in a square flat spiral shape that is repeatedly wound from the circumference to the center of the bottom surface A of the washing tub, and by such a shape, It may be disposed overlapping the bottom surface (A) in the shape.

Since the shape of the square planar spiral illustrated in FIG. 2 is exemplary, the interval between the spirals and the number of windings thereof can be adjusted as desired. It is also possible to increase the number of windings of the spiral to reduce the distance between the bodies 10 and to form a more dense spiral structure. The flat spiral shape of the body 10 corresponds to the shape of the bottom surface (A) of the washing bucket, and for example, the bottom surface (A) is filled while repeatedly winding along each side of the washing bucket bottom surface (A). can

Even if the body 10 is spaced apart at a certain interval, the bubbles generated in the hole 10a for bubble generation rise and merge or expand to act in a wider space. Therefore, the area of the bubble is substantially expanded to the space between the bodies 10, and the upper space can be filled with the bubble.

Since the body 10 is wound in a planar spiral shape, the bubble generating holes 10a are also arranged along the body 10 in a planar spiral shape formed by the body 10 as shown in FIG. 2 . Since a plurality of bubbles rise upward in a spiral shape from the bubble generating hole 10a arranged in a spiral shape, bubbles can be provided inside the washing space without substantial blind spots due to the spiral structure that is repeatedly wound.

In this embodiment, the body 10 is shown in a square planar spiral shape, but in other embodiments, the body 10 may be deformed into a non-rectangular circular planar spiral shape or the like. That is, when the washing tub (see 21 in FIG. 4 ) does not have a square tubular shape as in the present embodiment, the planar spiral shape of the body 10 may also be changed to correspond to the shape of the bottom surface of the tub. Through this, the present invention can be applied to various washing tubs.

Since the body 10 is bent in a planar spiral shape and the air inlet 11 is formed at one end of the outer side of the spiral, air is injected from the outside of the spiral toward the center toward the other end of the center. The fluid flowing inside the body 10 may show a pressure drop due to friction or viscosity, but since the body 10 has a spiral shape that is repeatedly wound, the pressure drop inside the body 10 is also a spiral formed by the body 10. may appear sequentially from the periphery toward the center.

Therefore, even if the intensity of the bubble (bubble) fluctuates, it changes step by step from the outside to the center of the spiral. For example, when creating a bubble with a straight pipe, a strong bubble is provided at the beginning of the pipe and the intensity of the bubble gradually increases. It can also solve the problem of separating strong and weak areas of bubbles by weakening them.

FIG. 3 is an operational diagram showing the action and effect of the detachable stopper separation and coupling of the bubble tube of FIG. 1 .

As shown in FIG. 3, such a bubble tube 1 is used in a state where the detachable stopper 13 is coupled to the body 10 and the waste outlet 12 is sealed [FIG. 3 (a)], At least two methods of opening the waste outlet 12 by separating the detachable stopper 13 may be used. When the detachable stopper 13 is coupled, the air injected through the air inlet (see 11 in FIG. 1 ) is discharged through the bubble generating hole 10a as shown in FIG. 3 (a), so bubbles (air bubbles) are generated underwater. do.

On the other hand, when the detachable stopper 13 is separated as shown in (b) of FIG. 3, since the air (B) passes through the dirt outlet 12 and comes out, dirt (C) and other accumulated dirt (C) in the body (10) with air pressure The debris can be easily removed. The state as shown in (b) of FIG. 3 may be a state in which the washing tub is drained after the washing is finished and air is injected through the air inlet (see 11 in FIG. 1 ).

Since the dirt (C) in the body 10 easily blocks the fine bubble generating hole 10a while flowing by air, it causes deterioration of the performance of the bubble pipe 1. Since the present invention can remove the dirt (C) immediately after washing by separating the detachable stopper (13) and opening the dirt outlet (12), the inside of the bubble pipe (1) is kept clean and the bubble pipe (1) Performance can also be maintained at its best. Hereinafter, with reference to FIGS. 5 and 6, the bubble tube cleaning method according to the present invention will be described in more detail.

4 is a use state diagram illustrating a state of washing with the bubble washer equipped with the bubble pipe of FIG. 1, and FIG. 5 is a use state diagram illustrating an operation of discharging dirt into the bubble pipe after washing in FIG. 4, and FIG. 6 is It is a flow chart showing a cleaning method of a bubble pipe for a bubble washer according to an embodiment of the present invention.

Hereinafter, the bubble pipe 1 of the cleaning method is substantially the same as the bubble pipe 1 described above, and therefore, repetition of the above-described parts will be omitted. The description of the cleaning method is based on the flow chart of FIG. 6, but proceeds in a manner in which the remaining drawings including FIGS. 4 and 5 are referred together as necessary.

The cleaning method of the bubble pipe according to the present invention is specifically configured as follows. Referring to FIG. 6, the cleaning method of the bubble pipe is the method of cleaning the bubble pipe (1) for the bubble washer described above, in which the washing tub of the bubble washer is filled with water and the object to be washed is accommodated in the bubble pipe (1). ) washing the object to be washed with the bubbles generated in [S100-step (a)], terminating the washing and draining the water filled in the washing bucket [S200-step (b)], Separating the detachable stopper to open the filth outlet [S300-step (c)], passing air from the air inlet of the bubble pipe 1 to the filth outlet and removing the filth from the inside of the body with air pressure [S400-step ( d)], and a step [S500-step (e)] of collecting and treating the filth coming out from the filth outlet side.

Hereinafter, each step will be described in more detail.

First, referring to FIG. 4, the washing step (S100) using bubbles E will be described. In FIG. 4, the bubble pipe 1 is applied to the bubble washer 2, and is disposed on the bottom surface A of the washing tub 21 of the bubble washer 2. The bubble washer 2 includes a bubble pipe 1, a washing tub 21, a drainage hole 22 formed in the washing tub 21, an ultrasonic vibrator 23 disposed in the washing tub 21, and a housing accommodating them therein. (24).

The shape or configuration of the bubble washer 2 is exemplary and therefore does not need to be limited to drawings or the like. Therefore, only the approximate shape of the housing 24 is shown with a dotted line, and the remaining parts other than necessary for description are omitted. The washing tub 21 is partially cut away to show the arrangement of the bubble tube 1. Although the ultrasonic vibrator 23 is disposed, the ultrasonic vibrator 23 does not necessarily need to be included in the bubble washer 2 . However, when the vibration of the ultrasonic vibrator 23 is added, the cleaning effect can be increased according to the vibration of the ultrasonic vibrator 23 .

The bubble washer 2 need not be limited to a specific type. There are various objects to be washed (not shown) that can be washed by the bubble washer 2. The bubble washer 2 is, for example, a dishwasher, a food washer capable of washing fruits, vegetables, or other agricultural and marine products, or another variety of different types of washing objects that can be washed with other bubbles. It can be a dishwasher. All of the bubble washers 2 may include a washing container 21, and the above-described bubble pipe 1 may be disposed in the washing container 21.

The bubble pipe 1 is disposed at the bottom of the washing bucket 21 and may be formed so that the air inlet 11 passes through the washing bucket 21 and communicates with the outside of the washing bucket 21 . Although not shown, the air inlet 11 may be connected to an air injection pump formed in the bubble washer 2 (not shown - for example, may be disposed in the lower part of the housing), etc. to receive air (compressed air, etc.) there is.

The other end located at the center of the spiral of the bubble tube 1 may overlap the drain hole 22 in the center of the washing tub 21 as shown in FIGS. 4 and 5 . Therefore, the treatment of the soil (C) described later can be performed more easily.

In this way, when water (D) is filled in the washing container (21) in which the bubble tube (1) is disposed and air (B) is injected through the air inlet (11), bubbles formed in the body (10) as shown in the enlarged view of FIG. Bubbles E are generated from the hole 10a for generation. The bubbles E rise from the hole 10a for bubble generation, and as described above, the internal space of the washing container 21 is filled without a substantial blind spot by the spiral structure formed by the body 10 .

As a result, as shown in FIG. 4 , the water D filled in the washing tub 21 is vibrated by the bubbles E. At this time, by accommodating the object to be washed (not shown) in the washing tub 21, the object to be washed may be washed with the bubbles E. As described above, the object to be washed may be dishes, fruits, vegetables, or other agricultural and marine products, or various other objects that can be washed with the bubble E.

During such washing, the ultrasonic vibrator 23 disposed in the washing bucket 21 may vibrate the water D of the washing bucket 21 to provide vibration F to the object to be washed (not shown). The cleaning effect on the object to be cleaned can be further increased by the synergistic effect of the bubble E and ultrasonic vibration. The washing process proceeds in this way.

Thereafter, the washing ends as shown in FIG. 5, and the water D filled in the washing container 21 is drained (S200). Water (D) may be drained through the drain hole 22 formed in the washing container 21 .

Thereafter, the detachable stopper 13 of the bubble tube 1 is separated to open the waste outlet 12 (S300). This can be done by rotating the detachable stopper 13 screwed together as shown in FIG. 3 to separate it from the waste outlet 12.

Thereafter, the air (B) is passed from the air inlet 11 to the waste discharge port 12, and the dirt (C) inside the body 10 is removed by air pressure (S400). That is, as shown in the enlarged view of FIG. 5, the air injected into the air inlet 11 is discharged through the waste discharge port 12 formed at the other end of the body 10, and by the pressure of the injected air, the body ( 10) Dirt (C) and other debris inside are also discharged.

At this time, it is also possible to perform control to increase the air pressure differentially from when washing. That is, as described above, in the cleaning step (S100), bubbles (see E in FIG. 4) are generated while discharging the air (B) injected through the air inlet 11 through the bubble generating hole 10a, but removing dirt (S400). The injection pressure of the air (B) provided to the air inlet 11 of ) can be controlled to be greater than the injection pressure of the air (B) provided to the air inlet 11 in the washing step (S100).

The injection pressure of the air B may be performed by adjusting the load of an air injection pump (not shown) connected to the air inlet 11 described above. Through these steps, dirt (C) or other debris in the body 10 can be removed very conveniently and effectively.

Thereafter, the waste (C) coming out of the waste outlet 12 is collected and treated (S500). The spiral structure of the body 10 is also useful when processing dirt (C). As shown in FIG. 5, the other end at which the waste outlet 12 is formed is located at the center of the bottom surface A of the washing tub 21 due to the spiral structure, so it easily overlaps with the drain hole 22 disposed in the center. Therefore, the filth C discharged through the filth outlet 12 can be directly removed through the drain 22 without a separate transfer process.

In this way, the inside of the bubble tube 1 can be cleaned immediately after bubble washing. Since the drainage process after washing and the cleaning operation of the bubble pipe 1 are directly linked, the performance of the bubble pipe 1 can be maintained at its best by cleaning the bubble pipe 1 every time it is washed. In this way, the bubble pipe 1 can be used.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art can understand that the present invention is possible in other specific forms without changing the technical spirit or essential features. There will be. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting.
