1 to 9 are views showing a nanobubble device 1 for a dishwasher according to an embodiment of the present invention. The nanobubble device 1 for a dishwasher according to this embodiment is a general home and restaurant Supplying nano-bubble water to the dishwasher 300 designed to wash the tableware 10 through braking control is applied in facilities requiring washing of various tableware 10, such as the water pipe 100. It can be particularly suitably applied to the dishwasher 300 connected to and used to wash the dishes 10 using tap water.

The nano bubble device 1 for a dishwasher according to this embodiment has a washing chamber 311 inside and spray nozzles for spraying washing water to wash the dishes 10 accommodated in the washing chamber 311. In the dishwasher 300 having the washing body 310 provided with the 320, nanobubble water containing microbubbles is supplied to the supply pipe 200 connected to the spray nozzle 320 to supply washing water. there is.

That is, after forming water supplied from the outside into nanobubble water, the water is supplied as washing water through the supply pipe 200 that is spatially connected to the injection nozzle 320 to supply washing water.

In the above, the end of the supply pipe 200 is exposed to the outside of the washing body 310 and can be supplied with washing water from the outside of the washing body 310; The configuration and structure of the cleaning body 310 is preferably made of a configuration and structure that can be suitably applied according to a user's selection among conventionally known technologies.

The nanobubble device 1 for a dishwasher according to the present embodiment made as described above has a pump chamber having an inlet through which water flows in, an outlet through which water is discharged, and a pump chamber configured to form a pump pressure for water between the inlet and the outlet. It rotates by receiving rotational force of the pump motor 32 configured to generate rotational force by receiving controlled power from the housing 31 and the control means 51 provided in the pump chamber and configured to control power of the power supply unit 52. a pump means (3) having a pump impeller to form a pump pressure in the pump chamber; The mixed water, which is a mixture of water pumped through the pump means 3 and having a transfer pressure, and air supplied from the outside, is sealed against the outside between the supply port supplied and the drain discharged to the outside, and the supply port and the drain port are mixed. A dissolving means (4) provided with a dissolving space to form a dissolving pressure of air for water;

in other words. When the mixing water supplied to the dissolving space (A) of the dissolving means (4) through the pump means (3) is supplied through the transfer pressure of the raw water, through the dissolving pressure formed inside the dissolving space (A). Nanobubbles are generated, and the generated nanobubble water is sprayed into the washing chamber 311 via the spray nozzle 320 through the supply pipe 200 to wash the dishes 10 .

In the above, the pump means 3 is preferably applied suitably according to the user's selection in a structure to which a conventionally known technique is applied.

In the above, the dissolving space (A) of the dissolving means (4) may be formed in the 'interspace' in which the supply port and the drain port are each spatially connected.

That is, the dissolving space A, the pump chamber, and the supply pipe 200 are spatially connected through the supply port and the drain port.

Accordingly, after the mixed water is nano-bubbled through the supply port from the outside of the dissolving means 4, it is sprayed while being applied as washing water to the inside of the washing chamber 311 via the drain hole and the supply pipe 200, may be used.

At this time, when the control means 51 detects the open state of the supply opening/closing valve 330 and closes the recovery valve 61 according to the application of the supply pipe opening/closing data obtained, the nanobubbles formed in the dissolving means 4 While water is supplied to the supply pipe 200 via the water supply pipe 210, it is sprayed through the spray nozzle 320 of the washing chamber 311 to wash dishes.

In this way, while the dishes 10 are being washed in the washing chamber 311 of the dishwasher 300, the supply opening/closing valve 330 of the supply pipe 200 is closed according to the drive control of the dishwasher 300. In the state of being, the recovery valve 61 is opened according to the supply pipe opening/closing data according to the degree of the closed state of the supply opening/closing valve 330 transmitted to the control means 51, while forming the above-described circulation path continuously. It forms nanobubble water.

In addition, when the supply opening/closing valve 330 of the supply pipe 200 is opened and the supply of washing water to the washing chamber 311 is restarted according to the control operation of the dishwasher 300, the control unit 51 ) detects the open state of the supply opening/closing valve 330 again, the recovery valve 61 is re-closed, and the nanobubble water formed in the dissolving means 4 passes through the water supply pipe 210 to the supply pipe 200. ) and is sprayed through the spray nozzle 320 of the washing chamber 311 to re-wash the tableware 10.

While the above processes are continuously and sequentially applied, the washing operation of the tableware 10 is performed.

When the washing of the dishes 10 by the dishwasher 300 is completed, the operation of the nanobubble device 1 for the dishwasher according to the present embodiment may be stopped by manipulating the main drive switch 53. .

At this time, the water supply valve 62 has a state in which the connection pipe 240 is closed so that tap water does not flow through the water pipe 100; The supply opening/closing valve 330 provided in the supply pipe 200 is closed; Preferably, the recovery valve 61 is opened to form an initialization state having a state in which the circulation path of water is maintained.
