Description

Microbubble generator connecting the water pipe using water directly from the water pipe

The present invention relates to a microbubble generating device for directly adding a microbubble to the direct water supplied from the water pipe is directly connected to the general water pipe.

Micro bubbles are a few microns in size, much smaller than ordinary air bubbles. In addition, fine bubbles rise at a slower speed in the water than ordinary air bubbles, so that they stay in the water for a long time, and when broken, high sound pressure and instantaneous high temperature are generated.

As the fine bubbles proceed to growth and breakdown, thermal decomposition of the air is carried out by instantaneous high heat in the gas region in which the air stays, and radicals are greatly activated in the interfacial region where air and water are mixed to oxidize. According to these physical and chemical properties are widely used in the sterilization field, cleaning field and the like.

Micro-bubbles used in household goods are washing water, beauty water, and the like vegetables and fruits. In Patent Document 1 or Patent Document 2, microbubbles are generated by impact by a combination of mechanical components such as protruding pins and discharge holes on a flow path of a showerhead connected to a faucet.

This conventional technology is a degree capable of generating fine bubbles when the water pressure is large enough, there is a disadvantage in that sufficient fine bubbles are not obtained due to low water pressure when connected to a commercially available water. Therefore, there is a limit to the use of the product, such as it is not widely used in ordinary households, but is widely distributed in commercial facilities such as hotels.

Furthermore, by releasing large amounts of general bubbles generated together with the micro bubbles as they are, there is a disadvantage in that high quality micro bubbles cannot be obtained.

In another embodiment, including a water tank unit for storing water, a suction pipe connected to the water pipe and the valve and the water sucked from the water tank passes, and a discharge pipe for discharging the bubble water of the pressure tank to the water tank unit, The present invention provides a microbubble generating device using direct water from a water pipe that circulates water stored in a tank and supplies microbubbles. Here, the water tank unit is a tub, a dishwasher, a sink, and the like.

In addition, it is possible to supply the bubble water by circulating the stagnant water, such as the dishwasher of the bathtub or sink, it has the advantage of supplying the bubble water for a long time without consuming additional tap water.

In addition, since the bubble water can be additionally supplied to the shower or other faucet, there is an advantage that can be used in a variety of applications.

The regulator unit ensures smooth supply of bubbled water by preventing air from escaping from the tap. In addition, the microbubble generating device is operated stably by operating the regulator unit to be activated or deactivated according to the water level inside the pressure tank. This has the effect of improving the operational reliability.

In addition, the venturi pipe lowers the minimum pressure of the air injected into the water pipe, thereby enabling the use of a low capacity air pump, and reducing the operation of the air pump to secure economical efficiency.

The mixing unit divides bubbles of tap water introduced into the pump part in advance and helps to easily generate fine bubbles. A large amount of even fine bubbles can be generated by the mixing portion, thereby improving the quality of the bubble water containing the fine bubbles.

Hereinafter, with reference to the accompanying drawings will be described the configuration, function and operation of the microbubble generating device using the direct water of the water pipe according to an embodiment of the present invention.

However, the same reference numerals for similar or identical components are used uniformly. In addition, in the drawing, the flow of air is indicated by a block arrow, and the flow of tap water is indicated by a solid arrow.

1 schematically shows a configuration of a micro bubble generator using the direct water of the water pipe according to an embodiment of the present invention.

The microbubble generating device 100 of the present invention is directly connected to the water pipe to which the tap water is supplied. That is, the present invention can generate tap water (hereinafter referred to as 'bubble water') containing microbubbles in daily life by generating microbubbles using direct water supplied from a water pipe.

When one micro bubble generator 100 is connected to the main water pipe of the home it is possible to supply the bubble water in both the bathroom and the kitchen. Therefore, there is no need to provide a separate micro bubble shower or washing machine as in the prior art.

Microbubble generating device 100 according to an embodiment of the present invention is a general air generated during the air injection unit (1) for injecting compressed air into the water pipe, the pump unit (2) to increase the generation of fine bubbles and the generation of fine bubbles It includes a pressure tank (3) for removing bubbles and temporarily storing the bubble water (W).

The air injection unit 1 includes an air pump 11 for compressing external air to generate compressed air, an air tank 12 for temporarily storing the generated compressed air, and a compressed water of the air tank to be injected into the water pipe. It includes an air pipe 13 for connecting the air tank.

If it is configured to inject oxygen supplied from a separately stored compressed oxygen tank into the water pipe, the air pump can be omitted. In this case, a compression tank for concentrating and storing various types of gases such as a compressed carbon tank may be connected instead of the compressed oxygen tank.

In order to generate the bubble water mainly containing a specific gas, a collecting device for collecting the gas component in the general atmosphere may be connected to the air pump. For example, in order to generate oxygen bubble water mainly containing oxygen, a collecting device for selectively passing oxygen such as a membrane may be connected to the inlet side of the air pump.

Alternatively, when the compressed air generated by the air pump is injected directly into the water pipe, the air tank may be omitted.

In the illustrated embodiment, the air pump 11 has a known configuration, and a description thereof will be omitted. The operation of the air pump 11 may be controlled according to the pressure conditions inside the air tank. For example, when the pressure inside the air tank 12 is lower than or equal to a pressure lower limit preset by the user, the air tank 12 may be The pressure operates the air pump 11 to the pressure upper limit set by the user. As a result, the pressure of the air tank retains the compressed air from the pressure lower limit set by the user to the pressure upper limit.

The air tank 12 is made of a pressure vessel to store compressed air.

The air pipe 13 is provided with a check valve 131. This prevents tap water from flowing back into the air tank 12 even if the pressure inside the air tank 12 is lower than the water supply pressure of the tap water passing through the water pipe, for example, such as a failure of the air pump or the interruption of air pump power. It is.

The air injection unit has an advantage of stably injecting air into the water flowing through the water pipe by injecting compressed air into the water pipe. The pressure of tap water supplied to the water pipe varies from home to home, but in a typical home, there is a pressure so that atmospheric air can not be directly injected into the tap water. In the present invention, by allowing compressed air to be injected into the water pipe, air bubbles may be formed by smoothly injecting air into the tap water.

In a configuration that can be omitted, the compressed air can be configured to be injected into the water pipe through the venturi pipe (4). 2 shows the structure of the venturi tube in a multi-sided view.

The inner flow path of the venturi tube 4 gradually narrows down according to the direction of the tap water, and then expands to its original size. An air hole 44 into which compressed air is injected is formed in the passage 43 whose diameter is narrowed between the inlet side 41 and the outlet side 42.

Tap water passing through the venturi tube 4 passes through the narrowed flow path 43, the flow rate increases and the pressure decreases. By configuring the compressed air to be injected in the section where the pressure is lowered, the pressure of the compressed air for injecting air into the flowing tap water can be lowered.

If the air pipe is directly connected to the water pipe without using the venturi pipe, the compressed air pressure must be higher than the tap water supply pressure so that the air can be injected into the tap water.

However, if the venturi tube (4) is used, the pressure of the tap water can be lowered than the water supply pressure in the section where the flow path is narrowed, and thus the minimum pressure value of the compressed air can be lowered. As a result, it is possible to use a low-capacity air pump or to lower the pressure lower limit, thereby excluding a high-capacity air pump and preventing frequent operation of the air pump.

In another omitted configuration, the pipe 5 through which the tap water injected with compressed air passes is provided with a mixing part 5 separating air. The mixing part 5 is installed along the longitudinal direction of the pipe to physically divide the air bubbles flowing through the inside of the pipe to divide the air bubbles finely.

3 is a detailed configuration of a mixing unit according to an embodiment of the present invention. The mixing part 5 includes a plurality of acute angle blocks 51 and a coupling part 52 fixing the acute angle blocks to the inner side surface of the pipe P while connecting the acute angle blocks. The coupling consists of a plurality of rib and frame frames.

The acute-angle block 51 is a wedge-shaped block body. A pair of inclined surfaces 511 are formed in the acute block 51 to meet at the front end, and both of the inclined surfaces 511 meet at an acute angle at the front end of the acute block to form a sharp acute part 512. The acute angle part 512 protrudes in the reverse direction with respect to the flow direction of tap water. Air bubbles are divided into two air bubbles along the inclined surface 511 by the acute angle 512. Both slopes are further away from the rear end to completely separate the air bubbles separated from the acute part.

In addition, the rear end of the acute angle block 51 is formed as a vertical plane cut almost perpendicularly to the flow direction of the tap water, the vortex is largely formed in the flow of tap water moving on the pipe (P) and the inclined surface. The vortex distorts the shape of the cut air bubbles and induces the air bubbles to collide with the acute parts 512 of the next acute block 51.

The acute-angle blocks 51 are spaced apart from each other along the longitudinal direction of the pipe P. Therefore, the air bubbles passing through the acute acute block 51 in the front are guided to be further divided by the acute acute block 51 after passing through the mixing time by the vortex.

Furthermore, neighboring acute block 51 is inclined obliquely along the central axis of the pipe (P), air bubbles collide with the acute part 512 of the next acute block 51 while passing sequentially through the acute block 51 Increased chances to do

As the acute block is provided with a plurality of at least two or more large air bubbles are separated into a plurality of small air bubbles, it is more easily separated into fine bubbles by the pump unit described later.

Referring back to FIG. 1, the pump unit 2 pumps tap water mixed with compressed air, and generates fine bubbles during the pumping process. Generation of fine bubbles by the pump unit 2 is caused by a collision with an impeller, a collision with a protruding protrusion during the pumping process. Such a pump unit 2 may have a configuration such as the non-patent document 1 described above, or may have a configuration of a micro bubble pump according to another known configuration.

Bubble water (W) discharged from the pump unit 2 flows into the pressure tank (3).

1 and 4 show the pressure tank.

Bubble water (W) flowing into the pressure tank 3 includes not only fine bubbles but also large bubbles (hereinafter, referred to as 'normal bubbles B').

In the pressure tank (3), the general bubble (B) quickly rises and rises to the surface, and is then destroyed. The fine bubbles not only rise very slowly, but also float in the bubble water for a long time due to the circulating flow formed inside the pressure tank 3 by the newly introduced bubble water.

Thereby, the pressure tank 3 can filter out the general bubble B from the bubble water W. FIG. After opening the outlet 31 of the pressure tank (3) it is possible to obtain a high-quality bubble water containing almost no ordinary bubbles.

The air of ordinary bubbles collects in the upper part of the pressure tank, and the volume and pressure gradually increase with the use of the micro bubble generator. In order to remove the air (A) of the upper portion of the pressure tank, the pressure tank (3) is provided with a regulator unit 33 for discharging the air inside.

The regulator part 33 may be a relief valve which is opened according to the pressure condition of the air collected in the pressure tank. By discharging the air inside the pressure tank by the regulator part 33, it is possible to prevent the air A inside the pressure tank 3 from escaping to the water outlet 31.

Furthermore, the regulator 33 is configured to be inactive when the level measured by the water level gauge 35 mounted inside the pressure tank is equal to or higher than a predetermined reference level.

Here, the water gauge 35 may be variously changed, such as a buoyancy device or an electronic sensor, according to a known configuration. In addition, the reference level is a level that is arbitrarily set by the user and is set at least higher than the outlet. For example, the reference level can be set at 70% of the pressure tank height.

If the bubble water level of the pressure tank (3) is more than the reference level there is no fear of air leaking into the outlet (31). In addition, when the pressure tank is filled with bubble water, there is a fear that the bubble water will leak to the regulator. Therefore, when the reference water level is higher, the operation of the regulator 33 is inactivated to prevent the air from the pressure tank from escaping.

The inactivation of the regulator unit 33 is provided with an electronic on-off valve 34 in the air discharge line 32, the on-off valve 34 so as to close the air discharge line 32 when measured above the reference level in the water gauge 35 By working.

As another example, the regulator unit may be configured as an electronic valve, and the regulator unit itself may be inactivated by directly receiving an electric signal of the water gauge.

The active or inactive operation of the regulator makes it possible to stably supply bubble water.

In addition, in the embodiment of the present invention, a control unit 7 for controlling the operation of the pump unit 2 and the air injection unit 1 is further included (see FIG. 5). The control unit receives the operation command from the user and controls the operation of the pump unit and the air injection unit 1. Since the water pressure of the water pipe is different for each place where the generator is installed, the pumping capacity of the pump unit and the compressed air injection amount are set differently for each installation site during the installation of the generator. The control unit is configured to change the pumping capacity of the pump unit and the operating pressure of the air injection unit according to the water pressure of the water pipe connected to the generator.

In addition, the control unit may control an additional operation of the air injection unit to remove the water remaining inside the generator as described below.

The microbubble generating device according to the present invention generates bubble water in the direct water supplied from the water pipe, and can stably generate a large amount of bubble water and supply it to various living waters. Therefore, it can be widely used in various applications such as washing water, beauty water.

5 is a view of the microbubble generating device according to another embodiment of the present invention.

Microbubble generating device according to another embodiment of the present invention includes an air injection unit 1, the pump unit 2, the pressure tank 3, the water tank unit 6, the suction pipe (P1) and the discharge pipe (P2). . Here, the configuration and operation of the air injection unit, the pump unit and the pressure tank is to include the technical features of the air injection unit, the pump unit and the pressure tank according to the above-described embodiment within the range not in conflict with the description below. , Duplicate descriptions are omitted.

The water tank unit 6 is any one of a tub, a dishwasher, and a sink, which are widely used in daily life, in which water is stored. The water tank can be a place or an object for storing water for the purpose of being used as daily water for washing and washing in daily life.

The discharge pipe P2 is connected to the pressure tank 3 and forms the outlet port in the above-described embodiment. The bubble water stored in the pressure tank 3 is discharged to the water tank unit 6 through the discharge pipe P2.

Water pipe (L) may be divided into the original water pipe (hereinafter referred to as 'cold water pipe (L1)') is supplied with water at room temperature and the hot water pipe (L2) is supplied with water heated by a boiler (not shown). . Water supplied from a general household is divided into a cold water pipe (L1) and a hot water pipe (L2), and each user is required to mix and use it properly.

Direct water supplied from the water pipe (L) in the drawing is a mixture of the water supplied from the cold water pipe (L1) and hot water pipe (L2) at an appropriate temperature. The mixing of cold water and hot water is done via a valve V1 of known construction.

Unlike illustrated, only the cold water pipe is used to generate the bubble water, and the discharge pipe may be connected to the hot water pipe through a well-known valve so that water of an appropriate temperature may be discharged.

Meanwhile, one end of the suction pipe P1 is connected to the water tank 6, and the other end thereof is connected to the water pipe L through the first valve V2. Here, the first valve V2 connects water mixed with hot water and cold water to the pump unit 2, or selectively connects the suction pipe P1 to the pump unit 2.

Furthermore, the first valve V2 may supply the water supplied from the water pipe and the water supplied from the suction pipe at a constant ratio to the pump unit.

In order to fill the empty water tank part 6 with bubble water, the 1st valve V2 is operated so that the water of the water pipe L may be supplied to the pump part 2. As described above, the compressed air is injected into the water, and the bubble water formed in the pump unit 2 is filled in the water tank unit 6 through the discharge pipe P2.

After the bubble water is filled to the water tank 6 at an appropriate level, the first valve V2 is switched to block the hot water or cold water supply and to supply water from the suction pipe P1. The negative pressure generated by the pump unit 2 causes the water in the suction pipe P1 to be re-introduced into the pump unit 2, whereby the bubble water is newly generated.

Thus, the continuous bubble water can be obtained while circulating the water filled in the water tank 6 through the suction pipe (P1) and the discharge pipe (P2). This circulation method can generate the bubble water for a long time with a certain quantity, thereby saving the amount of water required for bathing or washing.

Although not shown in Figure 5, the suction pipe is further provided with a filter means for filtering foreign substances contained in the water moving the suction pipe, the discharge pipe may be further provided with a heating means for heating the water. Here, the filter means may include a known adsorption filter such as a net or activated carbon, and the heating means may include a heating wire or a heat exchanger for instantaneously heating the discharge pipe.

In an additional configuration, the auxiliary discharge pipe (P3) is further connected to the discharge pipe (P2) that the bubble water is discharged from the pressure tank (3). This auxiliary discharge pipe (P3) is one end is connected through the discharge pipe (P2) and the second valve (V3), the other end is connected to the discharge portion (8) for discharging the bubble water.

Here, the second valve V3 selectively discharges the bubble water of the pressure tank to the water tank part or the discharge part 8. In addition, the discharge unit 8 is any one of the final discharge mechanism of the tap water in a general living environment, such as a faucet, a shower, a bidet, such as a bathroom or a kitchen. The discharge unit 8 may be composed of a plurality of discharge mechanisms in the shower of the bathroom, the faucet of the kitchen.

In another embodiment of the present invention, in the microbubble generating device, the control unit 7 is configured to further operate the air injection unit 1 for a predetermined time from the time when the operation of the pump unit 2 ends.

The microbubble generating device 100 may be installed inside the sink or under the bathtub. In this case, since the generator 100 is positioned lower than the water level of the water tank unit (washing tub or bathtub), water accumulated in the generator 100 may not be easily discharged. When the air injection unit 1 is operated for a predetermined time after the operation of the pump unit 2 is terminated, excess air injected into the water inside the pump unit 2 is pushed out and remains in the pump unit 2. It can drain water. Furthermore, when the compressed air is sufficiently injected, water accumulated in the pressure tank 3 can be completely discharged to the discharge pipe P2. As a result, the problem of decay of water accumulated in the generator 100 can be solved.
