Definitions

  • the present invention relates to a dishwasher with improved drying performance.
  • the dishes are dried with the drying step.
  • the drying step is very important in order to ensure that the dishes leave the dishwasher in a brighter and cleaner manner.
  • the water drops on the dishes are evaporated and removed from the dishes.
  • the evaporated water drops hit cold surfaces and moist air and condense thereon to be removed from the washing tub.
  • water vapor should be removed from the washing tub in a short time or condensed and then removed from the washing tub.
  • the vapor removed from the washing tub is quite dense and the temperature thereof is high. Therefore, discharging all the vapor from the washing tub at once may cause condensation and puddles in the external environment and may damage the external environment.
  • a dishwasher comprising the drying device includes a condensing duct.
  • a dishwasher comprising a storage container is a line section of the water supply which includes a water supply unit (16), which is fed from a water supply system and opens out in to a freely flowing stretch.
  • the aim of the present invention is the realization of a dishwasher with improved drying efficiency.
  • the dishwasher realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body; a washing tub which is disposed in the body and wherein the dishes to be washed are loaded; at least one lower rack and at least one upper rack which are disposed in the washing tub; at least one spraying member which sprays water onto the racks; a fan which enables the vapor in the washing tub to be sucked and discharged during the drying step; and a drying duct which receives the dense vapor sucked from the washing tub.
  • the drying duct opens into the washing tub through an opening. The process of removing dense vapor from the washing tub should be done in a short time, before the vapor hits the surface of the kitchen items. Thus, the washed kitchen items are dried in a short time.
  • the dishwasher of the present invention comprises an air guiding member which is connected to the drying duct through an opening from inside the washing tub and which enables the hot air coming from the drying duct to be guided.
  • the air guiding member By means of the air guiding member, the hot air drawn from the drying duct is guided to the bottom of the washing tub.
  • the dishwasher comprises a control unit which ensures that cold water is drawn from the mains to be accumulated on the bottom of the washing tub just before the drying step, and the air guiding member which provides that the hot air coming from the drying duct is delivered onto the cold water surface.
  • the air guiding member By means of the air guiding member, the hot air containing dense humidity evaporates by hitting the cold water surface. Thus, the temperature of the vapor in the washing tub is decreased.
  • the dishwasher comprises a tank which is disposed on the body, and the control unit which ensures that the water in the washing tub is delivered to the tank to be used in the new cycle after the drying step.
  • the drying performance is increased without changing the water consumption.
  • the dishwasher comprises the air guiding member having a first shell with a mouth portion connected to the opening and a second shell ensuring the formation of an air duct when joined with the first shell.
  • a duct is formed, thus providing the guiding of the air.
  • the dishwasher comprises a sealing member which is disposed on the mouth portion.
  • the air flow between the drying duct and the air guiding member is prevented from being uncontrollably delivered into the washing tub.
  • the pressurized water sprayed by the spraying members is prevented from entering the drying duct.
  • the dishwasher comprises the air guiding member having at least one slot and at least one claw disposed opposite to each other on the first shell and/or the second shell.
  • the dishwasher comprises the air guiding member having an end portion inclined towards the bottom of the washing tub.
  • the dishwasher comprises the air guiding member which is detachably attached onto the lower rack.
  • the air guiding member can be attached onto the lower rack.
  • the air guiding member can be easily removed and cleaned by the user.
  • the dishwasher comprises the air guiding member which can be attached and detached by sliding on the lower rack in a vertical plane by means of a guide provided on the side edges thereof.
  • the placement thereof is facilitated.
  • the dishwasher comprises the air guiding member having a stepped section arranged on the second shell.
  • the air guiding member can be used without preventing the upper rack from being brought to various positions.
  • a dishwasher comprising an air guiding member which enables the hot air coming from the drying duct to be delivered onto the cold surface formed in the washing tub.
  • the dishwasher (1) comprises a body (2); a washing tub (3) which is disposed in the body (2) and wherein the washing process is performed; at least one lower rack (4) and at least one upper rack (5) which are disposed in the washing tub (3) and whereon the kitchen items are placed; at least one spraying member (6) which sprays water onto the racks (4) to provide the performance of the washing process; a fan (7) which enables the moist air in the washing tub (3) to be sucked and discharged of the washing tub (3) during the drying process; a drying duct (8) which is disposed between the washing tub (3) and the body (2), which enables the moist air sucked from the washing tub (3) to condense, and one end of which opens into the washing tub (3); and an opening (9) which enables the air duct (8) to draw air from inside the washing tub (3).
  • the kitchen items are placed onto the racks (4).
  • the washing process is performed by spraying water by means of the spraying member (6).
  • the drying step is started to quickly remove water droplets from the kitchen items. Therefore, the vapor density in the washing tub (3) is enabled to reduced.
  • the fan (7) By means of the fan (7), the moist air is discharged from the washing tub (3), and the hot and humid air is guided through the drying duct (8).
  • the drying duct (8) opens into the washing tub (3) through the opening (9).
  • the dishwasher (1) of the present invention comprises an air guiding member (10) which is disposed in the washing tub (3), one end of which is connected to the drying duct (8) through the opening (9) and the other end extending towards the bottom of the washing tub (3).
  • the air guiding member (10) is disposed in the washing tub (3).
  • the hot air drawn from the washing tub (3) by means of the drying duct (8) is sent back into the washing tub (3) and delivered by means of the air guiding member (10).
  • the air is cooled and controlled.
  • the dishwasher (1) comprises a control unit (11) which ensures that the cold water taken from the mains is accumulated on the bottom of the washing tub (3) just before the drying step, and the air guiding member (10) which enables the hot air drawn from the washing tub (3) by means of the drying duct (8) to be delivered onto the cold water surface in the washing tub (3).
  • the air guiding member (10) which enables the hot air drawn from the washing tub (3) by means of the drying duct (8) to be delivered onto the cold water surface in the washing tub (3).
  • cold water is drawn from the mains into the washing tub (3) before the drying step begins.
  • a cold surface is formed on the bottom of the washing tub (3).
  • the hot air drawn from the washing tub (3) is sent back into the washing tub (3), the hot air is enabled to hit the cold surface to be condensed.
