[0001] The present invention relates to a nano-bubble water generator having one or more pressure tanks, and more particularly, to a compact, multi-purpose nano-bubble water generator capable of producing nano-bubble water in which an application gas such as air, oxygen, or hydrogen is dissolved at a certain pressure according to the intended use, and capable of automatically cleaning one or more pressure tanks on site to increase the operating efficiency of the system.

[0002] A representative prior art is disclosed in the inventor of the present application's registered patent No. 10-1999164 (July 5, 2019), titled "Nano bubble water generator containing applied gas", and in this registered invention, a nano bubble water generator (10) having two pressure tanks is provided, as shown in FIG. 1a, with a motor (1), a pump (2) coupled adjacent to the motor (1), a pump head (5) installed adjacent to the pump (2) to introduce water through a water inlet pipe (3) and a gas such as air and oxygen or hydrogen from a gas supply pipe (4) to have a certain pressure and mix them to generate raw water and oxygen water or hydrogen water, an induction pipe (6) through which the raw water and oxygen water or hydrogen water pass from the pump head (5), a first and second pressure tanks (7) and (8) that form a chamber with a certain pressure in a vacuum state inside from the induction pipe (6) and receive raw water and oxygen water or hydrogen water in sequence, and a second A bubble water discharge pipe (not shown) is installed at the bottom of the pressure tank (8), and it is composed of nano bubble water output units (20) that are connected to this bubble water discharge pipe and ultimately discharge fine nano bubble water generated as fine particles.

[0003] This nano bubble water output unit (20) is composed of a main body (21) having a screw portion formed on the body as shown in Fig. 1b, a first retainer (23) having a rim made of an elastic material such as silicone to surround a metal disc (23') having an orifice (22) formed as a micro-hole in the center to rapidly disperse bubble water, a second retainer (25) having a rim made of an elastic material such as silicone to hold a micro-mesh to finely crush the dispersed bubble water, a cylindrical ring (26) having a predetermined length to disperse the crushed bubble water in a cylindrical shape, and a sealing ring (27) inserted therein, which is sealed by being coupled to the screw portion of the main body (21) and has an end narrowly reduced to strongly output nano bubble water. Here, the first retainer (23), the second retainer (25), and the cylindrical ring (26) are positioned inside the main body (21) and the output tube (28) in the order in which they process water.

[0004] Therefore, the nano bubble water output unit (20) applied to the nano bubble water generator containing this application gas is intended to further finely atomize the nano bubble water discharged from the pressure tank, and tends to shorten the lifespan of the bubble water containing the application gas, making it unsuitable for producing drinking water.

[0005] In addition, the prior art was invented with the intention of manufacturing a large-scale nano-bubble water generator, and was not suitable for application to the generation of bubble water for household water purifiers or other special-purpose drinking water due to its structure not being suitable for miniaturization. In addition, it was not able to cope with cleaning to remove impurities such as water stains formed inside the first and second pressure tanks due to long-term use.

[0006] The main purpose of the present invention is to provide a compact, multi-purpose nano-bubble water generator capable of extending the drinking time of nano-bubble water in which an application gas such as air, oxygen, or hydrogen is dissolved at a certain pressure according to the intended use, and of increasing the operating efficiency of the system by enabling automatic cleaning of one or more pressure tanks on site.

[0007] Another object of the present invention is to provide a small multi-purpose nano-bubble water generator that produces nano-bubble water in a constant amount without fluctuation by making the quality of nano-bubble water containing a specific gas, such as air, oxygen, or hydrogen, dissolved in the pressure in one or more pressure tanks, uniform according to the purpose of use.

[0008] Another object of the present invention is to provide a small multipurpose nano-bubble water generator containing an applied gas that produces a constant amount of nano-bubble water applicable to a system of a small household water purifier for a specific purpose, or an applied gas bubble water such as air bubble water and oxygen or hydrogen bubble water, depending on the purpose of use of the system.

[0009] According to the present invention, a small multi-purpose nano-bubble water generator is configured with a first motor and a first pump for supplying air and an application gas such as oxygen or gas, a second motor for supplying water from a water supply section and a second pump integrally connected to the second motor, a pump head section installed adjacent to the second pump for simultaneously introducing water introduced through a water inlet pipe and an application gas such as air and oxygen or hydrogen from a gas supply pipe according to the purpose of use to generate a mixed water having a certain pressure, one or more pressure tanks connected to each other through a connection pipe to generate pressurized mixed water from the pump head section into fine bubble water, a power supply section for supplying power to the system, and an electronic control section for controlling the operation of the system by having a display section for displaying the operating status of the system.

[0010] A washing unit that supports a receptacle housing a second motor, a second pump, and a third motor for supplying washing water to wash one or more pressure tanks regularly or intermittently, which is installed on the upper surface of a bracket having one or more pressure tanks installed on the upper portion of the second motor, the second pump, and the pump head, and causes the third pump to supply washing water to one or more pressure tanks, a fine bubble water output control unit that controls the discharge amount of fine bubble water installed in the middle of a discharge pipe to adjust the internal pressure of the fine bubble water discharge pipe, and fine bubble water generating nozzles installed at the output terminal of the discharge pipe to further crush the fine bubble water and generate nano bubble water.

[0011] The washing section is composed of a support frame supported by four legs on the upper surface of the bracket, a column fixed to the center of the support frame and having a flap formed at the top, a receptacle housing a third pump coupled with a third motor in the flap installed at the top of the column, and pressurized washing water induction pipes that supply washing water supplied through a washing water supply pipe connected to a branch pipe to a pressurized washing water supply pipe pressurized to a certain pressure by the third pump.

[0012] The fine bubble water generating nozzle is composed of a main body formed with a lower body having a screw portion, a flange formed as a boundary between the lower body, and an upper body formed with an upper portion extending a predetermined distance from the flange and having a slit formed at the top, and a first retainer formed with an elastic material such as silicone to surround a metal disc having an orifice formed as a micro-hole in the center and diffusing nano-bubbles at a high speed, a second retainer formed with an elastic material such as silicone to hold a first fine mesh and pulverize the diffusion bubbles finely, and a cap-shaped pulverizing member formed with a cylinder having a second fine mesh installed on the upper edge and extending downward with a smaller diameter from the upper edge and having a plurality of slits formed around the circumference adjacent thereto, and an input portion formed with a screw portion formed inside so as to be coupled with the screw portion of the lower body, thereby simultaneously performing diffusion and pulverization of nano-bubbles from the end of the discharge pipe.

[0013] The electronic control unit first turns on the system and starts operation, determines whether the water supply operation mode is selected, and if the water supply operation mode is selected, performs the air bubble water operation mode, checks the adjusted bubble water discharge amount, and produces a certain amount of fine bubble water.

[0014] If it is not in the air bubble water operation mode, it determines whether the washing operation mode is authorized and if it is in the regular or intermittent operation mode, it performs the washing operation for a certain period of time.

[0015] When the operating mode is determined to be an application gas bubble water generation mode such as oxygen or hydrogen, application gas bubble water generation such as oxygen or hydrogen is performed, and the controlled bubble water discharge amount is confirmed to generate uniform bubble water of application gas fine particles.

[0016] The present invention can produce nano-bubble water in which an application gas such as air, oxygen, or hydrogen is dissolved at a certain pressure according to the purpose of use, and can automatically clean one or more pressure tanks on site to increase the operating efficiency of the system, thereby producing fine nano-bubble water with a uniform quality and controlled to ensure uniformity.

[0057] According to the present invention, as shown in FIGS. 2 and 3, a small multipurpose nano-bubble water generator (100) comprises a mixed water supply unit comprising a water supply unit (120) for supplying water or raw water, a raw water inlet pipe (101) for introducing water from the water supply unit (120), an application gas inlet pipe (113) connected to a first pump (112) coupled to a first motor (111) for supplying air and an application gas such as oxygen or hydrogen from an application gas supply unit (110), a mixing pipe (114) connected simultaneously to the raw water inlet pipe (101) and the application gas inlet pipes (113) for mixing the raw water and the application gas at a constant ratio and pressure, a branch pipe (115) connected to the outlet of the mixing pipe (114) for supplying only the raw water as washing water, and a mixed water supply pipe (116) connected to the branch pipe (115) for supplying mixed water in which the raw water and the application gas are mixed at a constant ratio.

[0058] The mixed water is supplied from the mixed water supply unit to the fine bubble water generation unit, and the fine bubble water generation unit is composed of a second pump (122) combined with a second motor (121) installed to pressurize the mixed water to a certain pressure, a pump head (130) installed adjacent to the second pump (122), an induction pipe (131) that guides the pressurized mixed water from the pump head (130) to a first pressure tank (123) that generates fine bubble water, a washing water supply pipe (132) that is connected to the induction pipe (131) and supplies washing water to the first pressure tank (123), and a first pressure tank (123) and a second pressure tank (124) that are connected to each other through a connection pipe (125) to generate the pressurized mixed water to be fine bubble water.

[0059] What is noteworthy here is that the first and second pressure tanks (123, 124) are formed as vacuum chambers inside and are equipped with spray nozzles that spray pressurized mixed water inside, thereby controlling the size of fine particles of the fine mixed water flowing inside and enabling discharge.

[0060] Meanwhile, in the present invention, a washing unit (140) for regularly or intermittently washing the first and second pressure tanks (123, 124) is installed on the upper surface of a bracket (135) in which the first and second pressure tanks (123, 124) are installed on the upper portion of the second motor (121), the second pump (121) and the pump head (130).

[0061] The washing unit (140) is composed of a support frame (141) supported by four legs (142) on the upper surface of a bracket (135), a column (143) fixed to the center of the support frame (141) and having a flap (not shown) formed at the top, a receptacle (144) housing a third pump (137) coupled to a third motor (136) in the flap of the column (143), and pressurized washing water induction pipes (147) that supply washing water supplied through a washing water supply pipe (145) connected to a branch pipe (115) to a pressurized washing water supply pipe (132) pressurized by a constant pressure of the third pump (137).

[0062] In the second pressure tank (124), a discharge pipe (126) is installed at the bottom thereof to discharge fine bubble water. In accordance with the principle of the present invention, a fine bubble water output amount control unit (150) is installed to control the discharge amount of fine bubble water by adjusting the internal pressure of the fine bubble water discharge pipe (126) to increase the application expandability of the system, and a fine bubble water generating nozzle (160) is installed at the output terminal to further crush the fine bubble water and generate nano bubble water.

[0063] The fine bubble water output amount control unit (150) is commercially available and has a brushless motor (151), and can be applied with the pressure regulator of the corresponding registered patent of Fig. 6 to control the cross-section of the fluid passage, and a solenoid valve or lift check valve can be applied.

[0064] As shown in Fig. 4, the fine bubble water generating nozzle (160) is composed of a first main body (165) formed by a lower body (161) formed with a screw, a flange (162) formed as a boundary with the lower body (161), and an upper body (163) formed with a slit (164) at the upper end and extending a predetermined distance from the flange (162).

[0065] The lower body (161) is provided with a first retainer (166) that rapidly diffuses nano-bubble water, which has a border formed with an elastic material such as silicone to surround a metal disc (172) having an orifice (171) formed as a micro-hole in the center, a second retainer (167) that finely crushes the diffused bubble water, which has a border formed with an elastic material such as silicone to hold a first fine mesh (173), and a cylindrical portion (168) that has a fine mesh (178) installed on the upper edge (177) and extends downward with a smaller diameter from the upper edge (177) and has a plurality of slits (179) formed around the circumference adjacent thereto, and cap-shaped crushing members (178) that perform diffusion and crushing of nano-bubble water at the same time are sequentially positioned, and an input portion having a screw portion formed inside so as to be coupled with a screw portion of the lower body is provided, so that diffusion and crushing of nano-bubble water are performed at the same time from the end of the discharge pipe.

[0066] The electronic control unit (200) is provided with a power supply unit (108) that supplies power to the system and a display unit (109) that displays the operating status of the system, thereby controlling the operation of the system and confirming the operating status.

[0067] This electronic control unit (200) controls the operation of the system as follows. First, when the system is powered on and operation begins, it is determined in step (201) whether the water supply operation mode is selected, and if the water supply operation mode is selected, it moves to step (202) to determine whether the air bubble water operation mode is selected. If the air bubble water operation mode is selected, it moves to step (203) to perform the air bubble water operation mode, and in step (204), the controlled bubble water discharge amount is confirmed and it moves to step (205) to produce a uniform amount of fine nano bubble water of uniform quality.

[0068] If it is not in the air bubble water operation mode, it moves to step (206) to determine whether the washing operation mode is approved. If it is in the washing mode, the washing operation is performed regularly or intermittently in step (207), and then the operation is temporarily stopped and put into a standby state.

[0069] If it is not a cleaning mode, it moves to step (208) and determines whether it is an applied gas bubble water generation mode such as oxygen or hydrogen. If it is not an applied gas bubble water generation mode, it returns to step (201), and if it is an applied gas bubble water generation mode such as oxygen or hydrogen, it moves to step (209) to perform applied gas bubble water generation, and then in step (204), the controlled bubble water discharge amount is confirmed and it moves to step (205) to produce a constant amount of nano applied gas fine bubble water with uniform quality.

[0070] As described above, the electronic control unit system according to the present invention produces cleaning water or specific application water depending on the intended use.
