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 is coupled to the lower side of the general filter 57, and a micro-column pipe line 63 connected to the 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.

A secondary drain pipe line 71 is connected to the water collecting tank 55 side of the micro-column pipe path 63 so as to communicate with the drain pipe path 67 through which the washing water discharged from the integrated pump 65 flows.

In addition, the guide portion 73 protrudes inside the pipe where the auxiliary drain pipe line 71 meets the drain pipe line 67 so that the washing water discharged from the integrated pump 65 does not flow into the auxiliary drain pipe line 71. It is formed.

Inside the pipe at the portion where the auxiliary drainage pipe 71 meets the micro-column pipe 63, the washing water from the integrated pump 65 flows easily to the microfilter side during washing, and at the microfilter side when draining. The baffle plate 74 is coupled so that the washing water introduced into the micro-column channel 63 does not flow to the integrated pump side.

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 second 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. And a flow path blocking having an L-shaped cross section so as to selectively block the first discharge port 79 or the second discharge port 81 by the flow force of the washing water generated according to the rotational direction of the rotor 77. The member 83 is hinged to the inside of the pump housing 75, the other side of the pump housing 75 is formed with an inlet 85 communicated with the circulation conduit 61 so that the wash water flows, and also the pump One side of the housing 75 to guide the washing water to the fine filter 59 An outlet 87 is formed in communication with the rum pipe 63, and a guide portion 89 is provided between the rotary body 77 and the flow path blocking member 83 to guide the flow path blocking member 83. It is structured.

The rotating body 77 is a fan or the like.

On the second discharge port 81 side of the integrated pump 65, a non-return valve 91 is provided 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 pipe line 65 is increased, and when the integrated pump 65 is rotated in reverse, fine particles passed through the fine filter 59 are contained. A baffle plate 93 inclined upward in the reverse rotation direction of the integrated pump 65 is coupled to the outlet 87 so that one 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 rotary body 77 in the integrated pump 65 rotates forward in the arrow F direction of the solid line as shown in FIGS. 4 and 5.

When the integrated pump 65 rotates in the direction indicated by the arrow F, the washing water in the washing tank 41 passes through the general filter 57, and the relatively large debris 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 portion of the washing water that rotates around the upper flange of the flow path blocking member 83 flows out through the outlet 87 along the arrow H to the micro galvanic channel 63. The baffle plate 93 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 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, the washing water hardly flows into the auxiliary drainage pipe line 71 by the inclined baffle plate 74.

In addition, the washing water is hardly discharged from the upper side to the lower side of the micro filter 59 by the injection force of the washing water sprayed into the micro 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 is rotated in the direction of the arrow G shown in FIG. 4 and FIG. 6 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. The baffle plate 93 inclined upward in the reverse rotational direction of the integrated pump 65 so that the washing water hardly flows 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 is formed by a dotted arrow through the gap S formed between the micro duct line 63 between the outlet end and the lower end of the micro filter 59. As it moves to the inlet side of the circulation pipe 61 and enters the pump housing 75 of the integrated pump 65 through the circulation pipe 61 and flows out through the drain pipe (67).

On the other hand, a part of the washing water containing fine debris flows into the auxiliary drainage pipe (71) through the micro-column pipe (63) is combined with the drainage pipe (67) and drained. At this time, since the washing water introduced into the micro-column channel 63 is blocked by the baffle plate 74, it does not flow to the integrated pump 65 side, and the guide portion 73 flows out along the drain line 67. The washing water does not affect the washing water flowing out along the auxiliary drainage pipe 71.

By this action, fine debris trapped in the fine filter 59 is automatically discharged at the time of drainage.

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 present invention, the dishwasher having an integrated pump can automatically discharge the fine waste caught in the fine filter upon draining, and since the washing water containing the fine waste is drained through the auxiliary drainage pipe, the waste water is drained. It takes less time.
