Abstract
A dish washer includes a cabinet, a tub positioned inside the cabinet, a sump provided in a lower portion of the tub, a case brake provided on a side wall of the tub connected to the sump, and a filter device positioned below the tub inside the cabinet, to selectively filter or unfilter water received from a water supply source, and to supply the filtered water or the unfiltered water to the case brake, the water passed through the case brake is collected in the sump, the case brake is located higher than the sump to prevent a backflow of the water collected in the sump to the case brake.
Claims12
A method of controlling a dish washer, the dish washer including a filter device to selectively filter or unfilter water, a case brake through which the filtered water or unfiltered water pass, a sump to which the water passed through the case brake is supplied, the method comprising:
- detecting an operation of filtering water received from a water supply source through a filter included in the filter device from among operations of the dish washer;
- in response to the detecting of an operation of filtering:
- opening a filtering flow path formed in the filter device so that the received water is filtered by the filter;
- supplying the filtered water to the case brake which is located higher than the filter device;
- and
- supplying the water passed through the case brake to the sump, the case brake located higher than the sump to prevent a backflow of the water collected in the sump to the case brake;
- and
- in response to not detecting of an operation of filtering:
- opening a bypass flow path formed in the filter device so that the received water bypasses the filter;
- supplying the unfiltered water to the case brake;
- and
- supplying the water passed through the case brake to the sump.
A method of controlling a dish washer, the dish washer including a filter device including a filter configured to filter a water, a filtering flow path configured the water to be filtered by the filter and a bypass flow path configured the water to bypassing the filter, and configured to selectively filter or unfilter water, a case brake through which the filtered water or unfiltered water pass, a sump to which the water passed through the case brake is supplied, a user interface through which an input signal from a user is received, a controller configured to receive the input signal from the user interface and to selectively open or close one of the filtering flow path or the bypass flow path based on the input signal, the method comprising:
- in response to the input signal being a signal for causing the water to pass through the filter:
- opening the filtering flow path by the controller so that the received water is filtered by the filter;
- supplying the filtered water to the case brake by the filter device, the case brake being located higher than the filter device;
- and
- supplying the water passed through the case brake to the sump by the case brake located higher than the sump to prevent a backflow of the water collected in the sump to the case brake;
- and
- in response to the input signal being a signal for causing the water to bypass the filter:
- opening a bypass flow path by the controller so that the received water bypasses the filter;
- supplying the unfiltered water to the case brake by the filter device;
- and
- supplying the water passed through the case brake to the sump by the case brake.
A dish washer comprising:
- a cabinet;
- a tub disposed in the cabinet;
- a sump provided in a lower portion of the tub;
- a case brake provided on a side wall of the tub and connected to the sump;
- a filter device disposed below the tub in the cabinet, to selectively filter or unfilter water received from a water supply source, and to supply the filtered water or the unfiltered water to the case brake and including:
- a filter configured to filter a water, a filtering flow path configured the water to be filtered by the filter, and a bypass flow path configured the water to bypassing the filter;
- a user interface configured to receive an input signal from a user;
- and
- a controller configured to receive the input signal from the user interface and to selectively open or close one of the filtering flow path or the bypass flow path based on the input signal,
- wherein the water passed through the case brake is collected in the sump, the case brake is located higher than the sump to prevent a backflow of the water collected in the sump to the case brake,
- when the input signal being a signal for causing the water to pass through the filter:
- the controller opens the filtering flow path so that the received water is filtered by the filter;
- the filter device supplies the filtered water to the case brake which is located higher than the filter device;
- and
- the case brake supplies the water passed through the case brake to the sump;
- and
- when the input signal being a signal for causing the water to bypass the filter:
- the controller opens a bypass flow path so that the received water bypasses the filter;
- the filter device supplies the unfiltered water to the case brake;
- and
- the case brake supplies the water passed through the case brake to the sump.
