Definitions
- Embodiments of the present disclosure relate to a dishwasher, more particularly, to a dishwasher which uses night-time electricity in performing a drying process which is the next step of the washing process, and a controlling method thereof.
- US2014/223761A concerns a method of controlling a dishwasher including driving a circulation fan and a heating unit in a circulation duct, which communicates with at least two portions of a tub, wherein water is condensed and removed by the circulation duct, and driving an exhaust fan to discharge the air in the tub to the outside.
- WO2015/119672A , JPH0819502A and EP0269917A each concern methods for drying dishes in a dishwasher.
- a dishwasher is the mechanism configured to wash and dry one or more dishes held therein by injecting wash water to the dishes at a high pressure. Specifically, wash water is injected in a washing tub where dishes are held at a high pressure and the injected wash water washes and clean out food scraps or contaminants from surfaces of dishes.
- Such a dishwasher is capable of filtering the food scraps contained in the wash water and reusing the used wash water. Also, the dishwasher has dishwashing detergent or liquid dissolved in the wash water to remove the food scraps smoothly and efficiently.
- Such the conventional dishwasher includes a case defining an exterior appearance; a washing tub provided in the case and defining a washing space for dishes; a driving unit provided in a lower portion of the washing tub and supplying, collecting, circulating and draining washing water for washing the dishes; lower/upper/top injecting nozzles injecting the washing water supplied by the driving unit to dishes; and lower/upper/top storage racks extractable between the lower/upper/top injection units within the washing tub and selectively accommodating dishes according to kinds and sizes of dishes.
- Each of the storage racks has a plurality of moving rollers installed in each lower surface and guide rails are provided in an inner wall of the washing tub.
- the guide rails guide the rollers for the storage racks to be retractable.
- a user opens a door of the dishwasher to start dishwashing and takes out one of the storage racks arranged in the washing tub. Then, the user puts one or more dishes in the taken-out storage rack and pushes the storage rack before closing the door, to put the dishwasher into operation so as to wash the dishes.
- the user puts the dishwasher into operation and the driving unit is implemented to supply wash water to the upper/lower/top injection nozzles independently or simultaneously, to start the washing process for the dishes put in the lower/upper/top storage racks.
- Such the dishwasher controls wash water to be heated to facilitate the solution of dishwashing detergent which is mixedly supplied together with the wash water and soak the food scraps stuck on the dishes for a long time, so that an overall dishwashing process can be performed smoothly.
- a conventional controlling method of such the dishwasher includes a preliminary washing step; a main washing step; a rinsing step; and a drying step.
- the preliminary washing step food scraps are soaked and a more reliable dishwashing process is able to be performed.
- a sterilizing step is further provided to irradiate ultraviolet rays to the dishes or heat the dishes at high temperatures the after the main washing step and the rinsing step, so as to restrain the propagation of germs or bacteria.
- the two methods include a circulation type drying method and an exhaustion type drying method.
- a circulation type drying method dishes are heated in the washing tub and moisture is evaporated from the dishes and changed into vapors and the vaporized air inside the washing tub is circulated and condensed in the dishwasher, so that the condensed water is drained outside.
- the exhaustion type drying method external dry air is sucked into the washing tub of the dishwasher and the dry air absorbs moisture from the vaporized air evaporated form the heated dishes and the moisture-containing humid air is exhausted outside so as to dry the dishes.
- the circulation type drying method out of the conventional controlling methods according to the related art has a disadvantage of a lower drying efficiency than the exhaustion type drying method in an aspect of drying efficiency.
- the exhaustion type drying method out of the conventional controlling methods according to the related art also has a disadvantage of high energy consumption, even though it is proper to the dishwasher as the drying method.
- the wash water inside the sump is heated to a preset temperature in the rinsing step for rinsing the washed dishes after the main washing step and the temperature inside the washing tub rises high enough to evaporate the moisture from the dishes, only to make the overall drying step longer.
- an object of the present invention is to address the above-noted and other problems.
- An object of the present disclosure is to provide a dishwasher which is capable of keeping a dried condition of dishes, even if a user leaves the dishes in the dishwasher after a drying process after a washing process, and a controlling method thereof.

- a still further object of the present disclosure is to provide a dishwasher which is capable of performing the drying process for drying the dishes after a washing process, using the night-time electricity which is relatively cheap, and a controlling method thereof.
- a controlling method of a dishwasher comprises a water supply step for supplying wash water to the dishwasher; a washing step for washing one or more dishes by using the wash water; a rinsing step for rinsing the washed dishes; a drying step for drying the rinsed dishes, and a dry maintaining step for intermittently drying the dishes to maintain a dried state of the dishes.
- the washing step may comprise a preliminary washing step for soaking food scraps or contaminants stuck on the dishes; and a main washing step for separating the food scraps or contaminants from the dishes.
- the controlling method of the dishwasher comprises a dry maintaining step for determining selection of the dry maintaining step after the drying step.
- the dry maintaining step intermittently operates a drying module of the dishwasher for a preset time period.
- the operation time of the drying module may comprise a preset pause time and a preset duration time of the drying module which is shorter than the pause time.
- the dry maintaining step may end based on determination of the drying module operation ending condition.
- the drying module operation ending condition may comprise one of a user's operation ending input, opening of a door and staring of another washing course.
- a dishwasher comprises a washing tub defining a space in which one or more dishes are paced; a storage unit movable from the washing tub; a driving unit provided in a lower unit of the washing tub and injecting wash water to the storage unit; a door opening/closing the washing tub and comprising a drying module drying the dishes; and a controller intermittently operating the drying module for a preset time period to maintain a dried state of the dishes placed in the washing tub.
- the controller operates the drying module after washing, rinsing and drying steps for the dishes to maintain the dried state of the dishes.

Description
- Embodiments of the present disclosure relate to a dishwasher, more particularly, to a dishwasher which uses night-time electricity in performing a drying process which is the next step of the washing process, and a controlling method thereof.
-
US2014/223761A concerns a method of controlling a dishwasher including driving a circulation fan and a heating unit in a circulation duct, which communicates with at least two portions of a tub, wherein water is condensed and removed by the circulation duct, and driving an exhaust fan to discharge the air in the tub to the outside. -
- Generally, a dishwasher is the mechanism configured to wash and dry one or more dishes held therein by injecting wash water to the dishes at a high pressure. Specifically, wash water is injected in a washing tub where dishes are held at a high pressure and the injected wash water washes and clean out food scraps or contaminants from surfaces of dishes.
- Such a dishwasher is capable of filtering the food scraps contained in the wash water and reusing the used wash water. Also, the dishwasher has dishwashing detergent or liquid dissolved in the wash water to remove the food scraps smoothly and efficiently. The dishwashers capable of enhancing washing efficiency by raising the temperature of wash water or generating steam, using a heater, have been widely popular.
- Such the conventional dishwasher includes a case defining an exterior appearance; a washing tub provided in the case and defining a washing space for dishes; a driving unit provided in a lower portion of the washing tub and supplying, collecting, circulating and draining washing water for washing the dishes; lower/upper/top injecting nozzles injecting the washing water supplied by the driving unit to dishes; and lower/upper/top storage racks extractable between the lower/upper/top injection units within the washing tub and selectively accommodating dishes according to kinds and sizes of dishes.
- Each of the storage racks has a plurality of moving rollers installed in each lower surface and guide rails are provided in an inner wall of the washing tub. The guide rails guide the rollers for the storage racks to be retractable.
- Meanwhile, a user opens a door of the dishwasher to start dishwashing and takes out one of the storage racks arranged in the washing tub. Then, the user puts one or more dishes in the taken-out storage rack and pushes the storage rack before closing the door, to put the dishwasher into operation so as to wash the dishes.
- Hence, the user puts the dishwasher into operation and the driving unit is implemented to supply wash water to the upper/lower/top injection nozzles independently or simultaneously, to start the washing process for the dishes put in the lower/upper/top storage racks.
- Such the dishwasher controls wash water to be heated to facilitate the solution of dishwashing detergent which is mixedly supplied together with the wash water and soak the food scraps stuck on the dishes for a long time, so that an overall dishwashing process can be performed smoothly.
- A conventional controlling method of such the dishwasher includes a preliminary washing step; a main washing step; a rinsing step; and a drying step. In the preliminary washing step, food scraps are soaked and a more reliable dishwashing process is able to be performed. Recently, a sterilizing step is further provided to irradiate ultraviolet rays to the dishes or heat the dishes at high temperatures the after the main washing step and the rinsing step, so as to restrain the propagation of germs or bacteria.
- Two methods may be proposed for the drying step. The two methods include a circulation type drying method and an exhaustion type drying method. In the circulation type drying method, dishes are heated in the washing tub and moisture is evaporated from the dishes and changed into vapors and the vaporized air inside the washing tub is circulated and condensed in the dishwasher, so that the condensed water is drained outside. In the exhaustion type drying method, external dry air is sucked into the washing tub of the dishwasher and the dry air absorbs moisture from the vaporized air evaporated form the heated dishes and the moisture-containing humid air is exhausted outside so as to dry the dishes.
- However, the circulation type drying method out of the conventional controlling methods according to the related art has a disadvantage of a lower drying efficiency than the exhaustion type drying method in an aspect of drying efficiency.
- Meanwhile, the exhaustion type drying method out of the conventional controlling methods according to the related art also has a disadvantage of high energy consumption, even though it is proper to the dishwasher as the drying method. In the exhaustion type drying method, the wash water inside the sump is heated to a preset temperature in the rinsing step for rinsing the washed dishes after the main washing step and the temperature inside the washing tub rises high enough to evaporate the moisture from the dishes, only to make the overall drying step longer.
- In addition, users usually collect and put a relatively much amount of dishes in the dishwasher. In this instance, such a much amount of dishes are put in the dishwasher and the conventional dishwasher has a disadvantageously deteriorated drying condition for the dishes having being washed and dried/kept therein.
- Accordingly, an object of the present invention is to address the above-noted and other problems.
- An object of the present disclosure is to provide a dishwasher which is capable of keeping a dried condition of dishes, even if a user leaves the dishes in the dishwasher after a drying process after a washing process, and a controlling method thereof.
- Furthermore, another object of the present disclosure is to provide a dishwasher which is capable of performing a drying process for drying the dishes after a washing process at late nights when the dishwasher is not used, and a controlling method thereof.
- Still further, a still further object of the present disclosure is to provide a dishwasher which is capable of performing the drying process for drying the dishes after a washing process, using the night-time electricity which is relatively cheap, and a controlling method thereof.
- To achieve these objects and other advantages and in accordance with the purpose of the embodiments, as embodied and broadly described herein, a controlling method of a dishwasher comprises a water supply step for supplying wash water to the dishwasher; a washing step for washing one or more dishes by using the wash water; a rinsing step for rinsing the washed dishes; a drying step for drying the rinsed dishes, and a dry maintaining step for intermittently drying the dishes to maintain a dried state of the dishes.
- The washing step may comprise a preliminary washing step for soaking food scraps or contaminants stuck on the dishes; and a main washing step for separating the food scraps or contaminants from the dishes.
- The controlling method of the dishwasher comprises a dry maintaining step for determining selection of the dry maintaining step after the drying step.
- The dry maintaining step intermittently operates a drying module of the dishwasher for a preset time period.
- The operation time of the drying module may comprise a preset pause time and a preset duration time of the drying module which is shorter than the pause time.
- The dry maintaining step may end based on determination of the drying module operation ending condition.
- The drying module operation ending condition may comprise one of a user's operation ending input, opening of a door and staring of another washing course.
- In another aspect of the present disclosure, a dishwasher comprises a washing tub defining a space in which one or more dishes are paced; a storage unit movable from the washing tub; a driving unit provided in a lower unit of the washing tub and injecting wash water to the storage unit; a door opening/closing the washing tub and comprising a drying module drying the dishes; and a controller intermittently operating the drying module for a preset time period to maintain a dried state of the dishes placed in the washing tub.
- The controller operates the drying module after washing, rinsing and drying steps for the dishes to maintain the dried state of the dishes.
- The door may comprise a manipulation unit for controlling the dishwasher, and the manipulation unit may comprise a dry maintaining step for intermittently operating the drying module for a preset time period.
