Description

A DISHWASHER WITH IMPROVED DRYING EFFECTIVENESS
The present invention relates to a dishwasher with improved drying effectiveness.
In dishwashers, after the washing and rinsing steps are completed, the drying step is carried out to dry the dishes in the washing tub. The drying step is based on the effective drying of the dishes by dehumidifying the hot steamy air in the dishwasher. The drying process is preferably carried out by means of a drying duct provided on the side of the dishwasher, in other words, between the dishwasher body and the washing tub. The hot and humid air generated at the end of the rinsing step is preferably suck into the drying duct by means of a fan, and said air is cooled by the ambient air between the dishwasher body and the washing tub in the drying duct, and the dehumidified air is sent back into the washing tub through the drying duct. This process continues until all the dishes in the washing tub are completely dry. When the drying process is completed, said air is discharged from the dishwasher through the drying duct. In the drying step, if the hot and humid air in the drying duct cannot be sufficiently dehumidified, this situation causes inefficient drying, thus prolonging the drying time and increasing the energy consumed by the dishwasher. In the state of the art, a heater is used or the drying process is carried out for long periods at low temperature in order to improve the drying performance. However, while the drying performance is improved in each process, energy consumption increases or user satisfaction decreases since the program duration is prolonged.
In the state of the art United States Patent Document No. US4179821, a dishwasher is disclosed, wherein the drying performance is improved by mixing the air taken from the outside with the air in the washing tub.
The aim of the present invention is the realization of a dishwasher with improved drying performance.
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; at least one spraying member which sprays water onto the dishes placed into the washing tub; at least one heater which heats the water; and an outlet opening which enables the hot air rising from the washing tub in the drying step to be discharged from the washing tub. The water heated by the heater is delivered onto the dishes. When the drying step starts after the washing process, the humid air formed by the hot water is separated from the dishes and is discharged from the washing tub through the outlet opening.
The dishwasher of the present invention comprises an inlet opening which is arranged close to the base of the washing tub and an outlet opening which is arranged in the washing tub in the farthest region from the inlet opening. The air from the outer environment is taken into the washing tub in a controlled manner through the inlet opening. An air flow is formed between the inlet opening and the outlet opening. By positioning the inlet opening and the outlet opening on a diagonal in the washing tub volume, it is provided that all of the humid air in the washing volume is discharged from the outlet opening by means of the air flow. Thereby, the drying performance is increased.
In an embodiment of the present invention, the dishwasher comprises a first shutter which is provided on the inlet opening and a control unit which controls the first shutter. In the washing step, the inlet opening is closed by means of the first shutter. The first shutter provided on the inlet opening and the control unit provide the intake of air at the beginning of the drying step. Thus, the washing performance is not affected by the first opening while the drying performance is improved.
In an embodiment of the present invention, the dishwasher comprises a second shutter which is provided on the outlet opening and a control unit which controls the second shutter. In the washing step, the outlet opening is closed by means of the second shutter. Thus, the washing performance is not affected by the second opening, and the second shutter provided on the second opening and the control unit enable the air to be discharged at the beginning of the drying step.
In an embodiment of the present invention, the dishwasher comprises a humidity sensor which is disposed in the washing tub and the control unit which controls the first shutter and the second shutter depending on the data received from the humidity sensor. When the humidity level in the washing tub is above a value predetermined by the manufacturer and saved in the control unit, the control unit opens and/or closes only the first shutter, or only the second shutter, or both the first shutter and the second shutter. Thus, the drying and washing performance is increased.
In an embodiment of the present invention, the dishwasher comprises a lid which is provided on the inlet opening and a guiding member which is provided on the lid. By means of the lid, the air of the outer environment is gathered in the vicinity of the inlet opening. By means of the guiding member provided on the lid, the air gathered on the lid is guided towards the inlet opening. Thus, the flow rate of the air is increased and the drying efficiency is improved.
In an embodiment of the present invention, the dishwasher comprises a channel which is provided on the outlet opening. By means of the channel, the air leaving the washing tub is enabled to be discharged in a controlled manner.
In an embodiment of the present invention, the dishwasher comprises a grate which is disposed on the inlet opening, and a plurality of moving fins which open/close the gaps in the grate. Thus, the air is filtered through the inlet opening and taken into the washing tub.
In an embodiment of the present invention, the dishwasher comprises an additional heater which is disposed on the inlet opening. By means of the additional heater, the air of the outer environment is heated before being taken into the washing tub. Especially in very cold weather, the cold air is heated before being taken into the washing tub, thus preventing any condensation in the washing tub.
In an embodiment of the present invention, the dishwasher comprises an odor capsule which is disposed on the inlet opening. Thus, it is provided that air with a clean odor is taken into the washing tub.
In an embodiment of the present invention, the dishwasher comprises the inlet opening in the form of an orifice. By means of the orifice form, the flow rate of the air taken into the washing tub and discharged therefrom by means of the outlet opening is increased. In an embodiment of the present invention, the dishwasher comprises the inlet opening in the form of a nozzle. By means of the nozzle form, the flow rate of the air taken into the washing tub and discharged therefrom by means of the outlet opening is increased.
By means of the present invention, a dishwasher is realized, wherein the drying performance is increased thanks to the natural air convection.
