At this time, the water supply hose 122 is a first water supply hose 122a connected between the water supply valve 124 and an external water source, and a second water supply hose connected between the water supply valve 124 and the water supply passage 126. 122b).

Therefore, the water purifier 140 may be installed at both the front and the rear of the water supply valve 124 based on the flow direction of water, but is installed at a connection portion between the water supply valve 124 and the second water supply hose 122b. When the water purifier 140 is disposed inside the dishwasher 100 to prevent deterioration in appearance due to the water purifier 140, the water supply valve 124 and the first water supply hose 122a are connected to each other. When installed, it is disposed outside the dishwasher 100 to improve installation and maintainability.                     

Hereinafter, the present embodiment is limited to the case where the water purifier 140 is installed before the water supply valve 124, and the water purifier 140 is configured in the same manner as the first embodiment described above, and thus, the detailed description will be provided. It will be omitted.

That is, the water purifier 140 is installed at the connection portion of the water supply valve 124 and the first water supply hose 122a, one side is assembled to communicate with the water supply valve 124, and the other side the water supply hose 122 The hose connector 128 to which the) is detachably connected is assembled in communication.

The hose connector 128 is a connection member for smoothly connecting the water purifier 140 and the first water supply hose 122a. The hose connector 128 is easily detached from the first water supply hose 122a and the first water supply hose. The first water supply hose 122a is hermetically connected to the connection portion 122a so that water does not leak.

Looking at the operation and effect of the dishwasher according to the third embodiment of the present invention configured as described above are as follows.

First, when the dishwasher is operated, the water supply valve 124 of the water supply device 120 is opened so that water is sumped from an external water source along the water supply hose 122, the water supply valve 124, and the water supply passage 126. 112 is supplied to the washing pump 114, the water is pumped and sprayed to the shelf 108 through the injection hole (110a) of the nozzle 110 to wash the dishes stored in the shelf (108).

At this time, as water is supplied from the external water source to the water supply valve 124 through the first water supply hose 122a of the water supply hose 122, installed between the water supply valve 124 and the first water supply hose 122a. The pollutant contained in the water is filtered by the water purifier 140, and the water purified by the water purifier 140 flows into the water supply valve 124.

The clean water flowing into the water supply valve 124 flows through the second water supply hose 122b and the water supply passage 126, and the water flowing through the water supply passage 126 is an ion resin of the softening device 116. The soft water reacts with to remove the hard water.

Then, when the ion resin is depleted due to the continuous washing operation of the dishwasher 100, the brine is added to the ion resin at the time when the washing operation is completed to regenerate the ion resin.

When the ion resin is regenerated by brine, the water supply valve 124 is opened to supply water to the ion resin storage tank, and the hard water component generated when the water is regenerated by the supplied water and the supplied brine are externally supplied. To be discharged.

On the other hand, since the water purifier 140 of the dishwasher of the present embodiment is configured and operated in the same manner as the first embodiment described above, a detailed description thereof will be omitted.

As described above, the water purifying apparatus for the cleaning mechanism according to the present invention has been described with reference to the illustrated drawings. However, the present invention is not limited to the above embodiments and drawings, and various modifications are made by those skilled in the art within the scope of the technical idea of the present invention. Of course this is possible.

That is, the cleaning mechanism is not limited to the washing machine and the dishwasher, and the water purifying device may be installed on the water supply passages of various apparatuses that perform the cleaning action using water.

The water purifying apparatus of the washing apparatus according to the present invention is installed on the water supply flow path of the washing machine or the dishwasher, so that the water used for washing the laundry or washing the dishes is purified more cleanly. There is an advantage that the use of an unnecessary detergent due to the contaminants contained in the water being improved and fed is prevented.

In addition, since the water purifying device is composed of a filter casing, a filter and a filter guide, and the filter is fixed by the filter guide and an internal flow path of the water purifying device is formed, the water purifying device is not only formed in a simple structure, There is an advantage that compactization is realized.

In addition, since the filter casing of the water purifying device is composed of a casing body and a cap, and a handle portion is formed on an outer surface of the cap, the cap is easily fastened to the casing body by manual labor, and the assembly of the cap and the casing body is There is an advantage to be improved.

In addition, a first sealing is installed between the casing body and the cap, and a second sealing is installed between the outlet of the casing body and the water supply passage, thereby preventing leakage through the connection portion of the water purifying device.

In addition, the water purifier ensures the performance of the washing machine and the dishwasher regardless of the water quality of the region where the washing machine and the dishwasher are used, thereby improving the reliability and stability of the product.
