The upper, middle and lower injection nozzles 47, 49 and 51 are provided with a plurality of small injection holes so that the water guided through the injection pipe passage 53 is injected at a high speed. It is provided so that it may rotate by the spring cooler type | mold at the edge part of the 53.

The injection pipe passage 53 is branched such that the washing water discharged from the first discharge port of the integrated pump 65 is divided into the upper, middle and lower injection nozzles 47, 49 and 51.

The microfilter 59 is coupled to the central portion of the sump 55, and the general filter 57 is coupled to the periphery of the microfilter 59. In this case, the general filter 57 serves to hold the fine filter 59. In addition, an inlet of the circulation pipe 61 communicates with a lower side of the general filter 57, and a micro-galling pipe line 63 connected to a pump housing of the integrated pump 65 below the micro filter 59. The exit of is in communication.

In the reverse rotation of the integrated pump 65, the fine debris attached to the fine filter 59 flows into the pump housing through the circulation pipe 61 and is discharged through the drain pipe line 67. A predetermined interval S is formed between the outlet end of the 63 and the lower end of the fine filter 59.

As shown in FIG. 4, the integrated pump 65 is coupled to a rotating body 77 that generates a flow force in the washing water as the pump housing 75 rotates, and the rotation of the rotating body 77 is performed. A first discharge port 79 and a first discharge port 81 communicating with the injection pipe passage 53 and the drain pipe passage 67 are adjacent to one side of the pump housing 75 so as to selectively discharge the washing water according to the direction.

As shown in Fig. 5, the outlet opening 87 has a flow path opening and closing means 93 coupled to the outlet port 87 so as to open and close the flow path to the micro galvanic pipe 63 according to the forward and reverse rotation of the integrated pump.

The passage opening and closing means 93 includes a base portion 95 forcibly pressed into a groove formed in the pump housing 75 of the integrated pump, and two protruding ribs 97 and 98 protruding from the base portion 95. consist of. The base portion 95 is formed with a hole communicating with the outlet 87.

The two protruding ribs 97 and 98 have elasticity so as to be opened and closed according to the flow strength of the washing water, and protrude toward the micro-column channel so that the ends of both protruding ribs 97 and 98 abut.

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 rotary body 77 in the integrated pump 65 rotates forward in the direction of the arrow F of the solid line as shown in FIGS. 4 and 6.

When the rotary body 77 of the integrated pump 65 rotates in the direction of arrow F, the washing water in the washing tank 41 passes through the general filter 57, and the relatively large residue is caught by the general filter 57. . The washing water passing through the general filter 57 passes through the circulation pipe 61 and flows into the pump housing 75 of the integrated pump 65, and then discharges toward the injection pipe path 53. The washing water flows out through the micro-column channel (63).

As shown in FIG. 4, in the integrated pump 65, the washing water passing through the circulation conduit 61 flows into the pump housing 75 through the inlet 85 and rotates in the direction of the arrow F. FIG. It rotates along the whole 77 and discharges through the 1st discharge port 79, 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 83 blocks the second discharge port 81 under the influence of the rotating washing water, and the washing water does not flow into the drainage pipe 67.

A part of the washing water flowing toward the first discharge port 79 is introduced into the micro-galvanic channel 63 through the outlet 87 while opening the protruding ribs 97 and 98 to both sides by the pressure.

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 portion of the washing water including the fine debris introduced into the pump housing 75 of the integrated pump 65 is discharged to the micro galvanic pipe path 63 through the outlet 87, as described above, the fine filter 59 It passes through the fine debris. At this time, almost no washing water flows out from the upper side of the fine filter 59 by the injection force of the washing water sprayed into the fine filter 59 at a high speed in the micro-column flow passage 63.

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. 4 and 7 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 75 of the integrated pump 65, and then the drainage pipe ( 67).

As shown in FIG. 4, in the integrated pump 65, the washing water passing through the circulation conduit 61 flows into the pump housing 75 through the inlet 85 and rotates in the direction of the arrow G of the dotted line. It rotates along the rotating body 77 to discharge through the second discharge port 81 to exit toward the drainage pipe (67).

At this time, the upper flange of the flow path blocking member 83 blocks the first discharge port 79 under the influence of the rotating washing water, and the washing water does not flow into the injection pipe line 53.

In addition, since the flow path blocking member 83 prevents the flow to the first discharge port 79 side, the amount of washing water is reduced on the first discharge port 79 side. Therefore, the elastic ribs 97 and 98 have elastic ends so that the washing water does not flow into the outlet 87 so that the washing water does not flow 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. Thus, the fine water through the gap (S) formed between the outlet end and the lower end of the fine filter 59, the fine water pipes are washed water containing fine debris of the circulation pipe 61 as indicated by the dotted arrows It moves to the inlet side and enters the pump housing 75 of the integrated pump 65 through the circulation pipe 61 and flows out through the drainage pipe 67.

Therefore, fine waste is automatically discharged when the washing water is drained.

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 channel opening and closing device of the dish chuck with an integrated pump according to the present invention, according to the forward and reverse rotation of the integral pump, the amount of washing water flowing into the micro galvanic pipe can be adjusted to effectively filter and discharge the fine debris. Will be.
