The rotating body 105 is a fan or the like.

On the second discharge port 109 side of the integrated pump 65, a non-return valve 119 is installed so that the washing water does not flow back from the drain pipe 67 to the integrated pump 65 side.

When the integral pump 65 is rotated forward, the flow rate flowing into the micro-column channel 63 is increased, and when the integrated pump 65 is reversed, fine particles passed through the fine filter 59 are contained. A baffle plate 121 inclined upward in the reverse rotation direction of the integrated pump 65 is coupled to the outlet 115 so that the washing water flows back into the micro-column channel 63.

Hereinafter, the operation of the present invention configured as described above will be described.

First, when power is applied to a water supply valve (not shown) under the control of the microcomputer while the faucet (not shown) is open, the solenoid in the water supply valve is operated to open the water supply valve, and the washing water passing through the water supply valve is a product. It is supplied to the inside of the washing tank 41 along the water supply hose (not shown) installed therein.

When the water level in the washing tank 41 reaches an appropriate level, the water supply valve is also shut off under the control of the microcomputer, and the integrated pump 65 is operated by the power supplied by the pressure generated by the operation of the integrated pump 65. The washing water in the washing tank 41 is pumped. At this time, the rotating body 105 in the integrated pump 65 is rotated forward in the direction of the arrow F of the solid line as shown in Figs.

When the integrated pump 65 rotates in the direction of the arrow F, the washing water in the washing tank 41 passes through the general filter 57, and the large waste is caught by the catch support 85, and the relatively large waste is stored in the waste storage (91). Inflow).

The washing water passing through the general filter 57 flows into the pump housing 103 of the integrated pump 65 through the circulation pipe 61, and then discharges toward the injection pipe path 53, and at the same time, The washing water flows out through the micro-column channel (63).

As shown in FIG. 7, in the integrated pump 65, the washing water passing through the circulation conduit 61 flows into the pump housing 103 through the inlet 113 and rotates in the direction of the arrow F. As shown in FIG. It rotates along the whole 105 and discharges through the 1st discharge port 107, and it goes out toward the injection pipe path 53. As shown in FIG.

At this time, the lower flange of the flow path blocking member 111 blocks the second discharge port 109 under the influence of the rotating washing water, and the washing water does not flow into the drainage pipe 67. A portion of the washing water that rotates around the upper flange of the flow path blocking member 111 flows out through the outlet 115 through the outlet 115 along the arrow H to the micro galvanic channel 63. The baffle plate 121 inclined upward in the reverse rotation direction of the integrated pump 65 increases the amount of washing water flowing into the micro galvanic pipe 63.

The washing water introduced into the injection pipe line 53 branches along the pipe line and flows into the upper, middle, and lower nozzles 47 and 49 and 51, and the upper and middle nozzles 47 and 49 and 51 respectively. At the same time as to rotate and remove the food debris on the table (P) placed in the upper and lower baskets (43, 45) at a high speed through the injection hole.

The food waste falls with the washing water to the bottom of the washing tank 41 and at the same time is filtered while passing through the general filter 57 disposed of the sump (55). At this time, the relatively large food waste is not caught by the general filter 57 and is not introduced into the integrated pump 65, and only the washing water including the fine waste passes through the general filter 57 and is supplied back to the integrated pump 65. Continue.

On the other hand, a part of the washing water including the fine debris introduced into the pump housing 103 of the integrated pump 65 is discharged to the micro-galvanic passage 63 through the outlet 115, as described above, the sump 55 To reflux).

At this time, the washing water rising through the injection pipe portion 71 is passed through the waste discharge pipe 73 through the central hole 97 to the fine filter 59, while the fine waste is caught, while rising through the injection pipe portion 71 Part of the washing water to pass through the hole 99 so that the relatively large debris collected in the waste storage box 91 does not flow into the circulation pipe (61).

While repeating such an operation, relatively large food residues and fine food residues in the washing water are caught by the general filter 57 and the fine filter 59.

Next, when the cleaning is performed for a predetermined time, the integrated pump 65 rotates in the reverse direction of the dotted arrow G as shown in FIGS. 7 and 9 under the control of the microcomputer.

When the integrated pump 65 rotates in the direction indicated by the arrow G of the dotted line, the washing water in the washing tank 41 passes through the circulation conduit 61 and flows into the pump housing 103 of the integrated pump 65, and then the drainage pipe ( 67).

As shown in FIG. 7, in the integrated pump 65, the washing water passing through the circulation conduit 61 flows into the pump housing 103 through the inlet 113 and rotates in the direction of the arrow G of the dotted line. It rotates along the rotating body 105 to be discharged through the second discharge port 109 to go toward the drainage pipe 67.

At this time, the upper flange of the flow path blocking member 111 blocks the first discharge port 107 under the influence of the rotating washing water, and the washing water does not flow into the injection pipe line 53. The baffle plate 121 inclined upward in the reverse rotational direction of the integrated pump 65 so that the washing water is hardly introduced into the micro galvanic pipe 63.

Since the washing water hardly flows into the inside of the micro-column channel 63, the washing water at the bottom of the washing tank 41 passes through the microfilter 59 so that the fine debris from the microfilter during dish washing falls downward. As shown in FIG. 4, the washing water containing fine debris through the gap S formed at the upper end of the injection pipe part 71 is moved to the inlet side of the circulation pipe 61 as indicated by the dotted arrow. It flows into the pump housing 103 of the integrated pump 65 through the pipe line 61 and flows out through the drain pipe line 67.

In addition, the relatively large debris collected in the debris storage box 91 flows into the circulation conduit 61 through the hole 99 and flows out through the drain conduit 67 through the integrated pump 65.

On the other hand, since the non-return valve 91 is provided at the second discharge port 81 side of the integrated pump 65, the washing water flows back from the drainage pipe 67 to the integrated pump 65 at the time of washing and draining the washing water. I never do that.

As described above, according to the filter device of the dishwasher having an integrated pump according to the present invention, the structure of the dishwasher, which is limited by space, is simplified, and the space constraints in manufacturing the dishwasher are reduced, When draining, it is automatically discharged and it can effectively filter the residue.
