Of course, a solenoid valve 51 that determines whether water is supplied is connected to the front of the water filter 50. In addition, the water collecting pipe 10 is also directly connected to the direct pipe 60 is to supply the general tap water. Of course, the direct pipe 60 is also connected to a solenoid valve 61 for determining whether water is supplied.

By such a configuration, only the purified water may be supplied to the water collecting chamber 10, the purified water and the general tap water may be mixed, or the general tap water may be supplied through the direct pipe 60. Preferably, the water used in the rinsing course can collect and use only the water passing through the water filter 50, thereby further improving the hygiene state of the tableware.

The bidirectional pump 20 is coupled to one side of the collection chamber 10 as described above. The bidirectional pump 20 is connected to a lower pipe 23 connected to the lower rotor 30 so as to supply water only to the above-described lower rotor 30, and also to supply water only to the above-described back nozzle 40. A bagpipe 24 connected to 40 is connected.

Therefore, the present invention supplies water to the lower rotor 30 only by the bidirectional pump 20, or supplies water only to the back nozzle 40, or alternately to the lower rotor 30 and the back nozzle 40. By supplying water to the furnace, it is possible to minimize the amount of water used.

The lower rotor 30 is configured to spray high pressure water from the lower part of the washing tank 2 to the upper direction during the washing or rinsing course of dishes.

In addition, the bag nozzle 40 is configured to spray high pressure water from the rear of the washing tank 2 to the front during the washing or rinsing course of the dishes.

Since the drain pump 80 is connected to the collection chamber 10, after the washing or rinsing of the dishes is completed, all the dirty water in the collection chamber 10 can be discharged to the outside of the washing tank 2.

The blower 70 is installed at one side of the collecting chamber 10. When the drain pump 80 operates to discharge all the water in the washing tank 2, the heating unit 13 is operated to operate the inside of the washing tank. The blowing fan 71 of the blower 70 is operated while the temperature of the heat sink becomes relatively hot, so that drying of the dishes is completed more quickly. That is, the hot air in the washing tank 2 is circulated more quickly by the blower 70, so that the dishes are dried faster.

As shown in the drawing, the lower rotor 30 is installed at the lower part of the washing tank 2, and the bag nozzle 40 is installed at the rear of the washing tank 2. On the other hand, most of the components, such as the collection chamber 10, the two-way pump 20, the water filter 50, etc. described above are not visible to the outside by the bottom surface 4 installed in the lower portion of the washing tank (2). In the drawings, reference numeral 14 denotes a water collecting cover installed at an upper portion of the water collecting chamber 10, and reference numeral 72 denotes an air blowing cover installed at an upper portion of the air blowing unit 70.

On the other hand, the lower rotor 30 is installed to rotate in a predetermined direction by water pressure on the bottom surface 4 of the washing tank (2), and a plurality of injection holes 31 are formed on the surface in different directions. . The injection hole 31 is to rotate the lower rotor 30 in a predetermined direction by the direction of the water to be sprayed, and to allow the water to be sprayed in various directions, the washing or rinsing efficiency of the dish is improved. Of course, the lower rotor 30 is connected to a lower pipe 23, not shown.

In addition, the back nozzle 40 is formed with a plurality of injection holes 41 to inject water from the rear of the washing tank (2) to the front. However, since the bag nozzle 40 is fixed to the rear of the washing tank 2, it does not rotate or move in a predetermined direction. However, since the directions of the injection holes 41 formed in the bag nozzle 40 all face different directions, the water spraying directions are all different so that the washing or rinsing efficiency of the dishes is further improved.

Further, the bag nozzle 40 is composed of a first bag nozzle 42 disposed in a substantially straight direction at the top and a second bag nozzle 43 disposed in a substantially straight direction at the top thereof, for example, a washing tank 2. The water is sprayed to the upper portion of the dish basket and the lower portion of the dish basket mounted inside, but the shape of the back nozzle 40 is not limited to this form. Of course, this bag nozzle 40 is connected to a bag pipe 24 which is not shown.

Figure 4 is a partially exploded perspective view showing a two-way pump in the dishwasher according to the present invention.

Is installed. Accordingly, when the direction of rotation of the impeller 21 is adjusted, the water of the water collecting chamber 10 described above is supplied to the lower rotor 30 along the lower pipe 23 or the back nozzle 24 along the bag pipe 24. It is supplied toward 40.

5 is a flowchart illustrating a control method of a dish washing machine according to the present invention. A control method of the dish washing machine will be described with reference to FIGS. 1 to 4.

First, when the power is applied, the user selects a predetermined course (S1). For example, the user may artificially select one of washing, rinsing, and drying steps. Of course, the user may select the automatic course, so that the washing, rinsing and drying of the tableware may be automatically performed sequentially. In the following description, the operation will be described on the assumption that the user selects the automatic course.

First, the control unit 90 operates the solenoid valve 51 installed at the front end of the water filter 50 or the solenoid valve 61 installed in the direct pipe 60 so that a predetermined amount of water is collected in the collection chamber 10. (S2)

For example, the control unit 90 may operate only the solenoid valve 51 of the water filter 50 to collect only the purified water in the collection chamber 10. In addition, the control unit 90 operates all the solenoid valves 51 and 61 installed in the water filter 50 and the water pipe 60, respectively, and the water and the water purified in the water collection chamber 10 are mixed and collected. You can also In addition, the control unit 90 may operate only the solenoid valve 61 installed in the direct pipe 60 so that only the direct water is collected in the collection chamber 10. Preferably, the control unit 90 operates only the solenoid valve 51 connected to the water filter 50 in the rinsing course, so that only the purified water is collected in the collection chamber 10, and the solenoid valve in the general cleaning course. By operating only (1), only the direct water is collected in the water collecting chamber 10, so as to increase the life of the water purification filter 50 as much as possible and use water efficiently. However, the present invention does not limit the collecting method only to this method.

In addition, the control unit 90 allows power to be applied to the heating unit 13 installed in the collection chamber 10 during the collection, thereby increasing the temperature of the collected water. As such, when the temperature of the water collected in the collection chamber 10 rises, the efficiency of washing or rinsing the dishes becomes better. In addition, the control unit 90 controls the temperature of the water by using the temperature sensor 11 installed in the water collecting chamber 10, and further adjusts the amount of water collection using the water level sensor 12.

Subsequently, the control unit 90 applies power to the bidirectional pump 20 to operate the lower rotor 30 or the back nozzle 40. (S3, S4)

For example, the controller 90 adjusts the rotational direction of the impeller 21 installed in the bidirectional pump 20 in one direction so that high pressure water is injected from the lower rotor 30 first. Then, the lower rotor 30 sprays water in the upper direction while rotating in a predetermined direction by water pressure, thus mainly washing and rinsing the lower part of the tableware. Since the inside of the tableware is washed and rinsed by the action of the lower rotor 30, it is usually preferable to control the operation time of the lower rotor 30 longer. Subsequently, the controller 90 reversely sets the rotation direction of the impeller 21 so that high pressure water is injected from the bag nozzle 40. Of course, water is hardly sprayed from the lower rotor 30 at this time. The back nozzle 40 then sprays water from the rear to the front, thereby washing or rinsing the outer surface of the dish. Since the water sprayed from the bag nozzle 40 as described above mainly wash the outer surface of the tableware, the time is preferably controlled relatively shorter than the operating time of the lower rotor (30).

Subsequently, after several operations of the lower rotor 30 and the back nozzle 40 as described above, since the contamination state of the water collected in the collection chamber 10 is severe, the controller 90 applies power to the drain pump 80. (S5) That is, the contaminated water in the water collecting chamber 10 by the drain pump 80 to be all discharged to the outside.

Subsequently, the controller 90 determines whether the above-described series of steps has exceeded a certain number of times. For example, it is determined whether the above-described series of steps has been repeated about three to four times. Of course, if the determination result is less than or equal to a predetermined number of times, the steps S2 to S5 are repeatedly performed.

On the other hand, if it is determined that the series of steps have been repeated three to four times, the control unit 90 to allow more power to be applied to the heating unit 13 installed in the collecting chamber 10 to the temperature inside the washing tank (2) Is relatively hotter, and also operates the blower fan 71 of the blower 70 so that the air in the washing tank 2 is rapidly circulated. (S7) In this way, the dishes in the washing tank 2 It dries quickly and the operation of the dishwasher is complete.

As described above, the dishwasher according to the present invention by using a bi-directional pump, water is sprayed through only the lower rotor, or only through the back nozzle, or the lower rotor and the back nozzle is operated sequentially during the dish washing or rinsing course By spraying water, the amount of water used can be greatly reduced.

In addition, the present invention by adopting a water filter, it is possible to improve the hygiene state of the dishes by washing or rinsing the dishes with clean water than normal tap water.

In addition, the present invention by using the heating unit during the drying course to relatively heat the temperature inside the washing tank at the same time circulating the wind through the blower, the drying of the tableware is performed quickly.

What has been described above is just one embodiment for implementing a dishwasher according to the present invention, the present invention is not limited to the above embodiment, the subject matter of the present invention as claimed in the utility model registration claims below Without departing, anyone with ordinary knowledge in the field to which the present invention belongs will have a technical spirit of the present invention to the extent that various modifications can be made.
