[0001] The present invention relates to a washer comprising a tablet detergent dosing unit.
[0002] A state of the art dishwasher comprises a washing tub wherein the dishes to be washed
are placed, a door which opens/closes the washing tub, and a detergent dispenser wherein
the detergent is placed. In the state of the art dishwasher, the detergent dispenser
is usually arranged on the inner surface of the door. The user generally fills the
detergent dispenser with gel detergent, powder detergent, or tablet detergent. The
detergent dispensers used to dispense a tablet detergent into the washing tub are
known in the state of the art. A state of the art detergent dispenser usually comprises
a main body which has a compartment wherein a tablet detergent is manually placed
and a pivotable lid which opens/closes the compartment. The lid is generally hinged
onto the main body. The state of the art detergent dispenser generally has a lock
mechanism which locks/unlocks the lid. The lock mechanism generally has a spring which
moves the lid from the closed position towards the open position such that the lid
opens when the lock mechanism is unlocked. In the state of the art dishwashers, the
control unit operates the lock mechanism so as to unlock the lid at a predetermined
stage of the washing process. Thus, the tablet detergent falls into the washing tub
with the effect of gravity . However, the user has to add a new tablet detergent in
each cycle. This causes problems such as storing tablet detergents outside or the
user forgetting to add detergent.
[0003] In the state of the United States Patent Document No.
US2022175212, a tablet detergent dosing unit is disclosed.
[0004] The aim of the present invention is the realization of a dishwasher wherein the tablet
dosing operation can be performed automatically.
[0005] 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 washing process is performed; a
door which is disposed on the body and which closes the washing tub; and a detergent
dosing unit which is disposed on the inner surface of the door and which has a storage
unit with a plurality of housings thereon, and a motor. The tablet detergent is placed
in the storage unit provided on the dosing unit. The storage unit is moved by means
of the motor such that the tablet detergent reaches the washing tub.
[0006] The dishwasher of the present invention comprises a lid which is disposed on the
detergent dosing unit. The lid has a filling opening and a discharge opening thereon.
The filling opening opens onto the housings. The discharge opening opens into the
washing tub. Thus, it becomes easier to fill the tablet detergent into the detergent
dosing unit to be delivered into the washing tub.
[0007] In an embodiment of the present invention, the dishwasher comprises the detergent
dosing unit which has a filling mode wherein the storage unit rotates continuously
at a certain angle and an operation mode wherein the tablet detergent is delivered
into the washing tub, and a control unit which enables the filling mode and the operation
mode to be controlled. When the detergent dosing unit is in the filling mode, the
user adds the tablet detergent through the filling opening and the housings on the
storage unit are filled step by step. In the operation mode, the tablet detergent
is enabled to be delivered into the washing tub during the washing process.
[0008] In an embodiment of the present invention, the dishwasher comprises a first sensor
which detects the presence of the tablet detergent in the filling opening and the
control unit which enables the detergent dosing unit to switch to the filling mode
when the first sensor is triggered. When the user adds the tablet detergent through
the filling opening, the detergent dosing unit automatically switches to the filling
mode and the storage unit starts to rotate at certain intervals.
[0009] In an embodiment of the present invention, the dishwasher comprises a movement mechanism
which is disposed between the lid and the storage unit and which enables the tablet
detergent to be delivered from the storage unit to the washing tub. By means of the
movement mechanism, the tablets in the storage unit are delivered into the washing
tub in order and used in the washing process.
[0010] In an embodiment of the present invention, the dishwasher comprises the movement
mechanism which has a first door to which the tablet detergent in the housing is delivered,
a chamber which receives the tablet after the first door, a second sensor which is
disposed on the chamber, and a second door which opens when the second sensor is triggered.
The chamber is positioned between the first door and the second door. The second sensor
disposed on the chamber is triggered by means of the tablet detergent such that the
second door is opened and the tablet detergent is delivered into the washing tub.
Since the tablet detergent passes through two different doors while being delivered
from the storage unit to the washing tub, uncontrolled dosing is prevented and the
tablet detergent is not damaged by water or heat.
[0011] In an embodiment of the present invention, the dishwasher comprises the control unit
which enables the storage unit to be rotated again when the tablet detergent is not
detected on the chamber in the operation mode. The storage unit is rotated again in
case there are empty housings on the storage unit. Thus, the washing process is prevented
from taking place without tablet detergent.
[0012] In an embodiment of the present invention, the dishwasher comprises the control unit
which enables the detergent dosing unit to switch from the operation mode to the filling
mode when the presence of a tablet is not detected in the chamber when the storage
unit is rotated as many times as the number of housings. Thus, it is determined that
the storage unit is empty. By switching to the filling mode, it is ensured that the
washing process is not performed without tablet detergent.
[0013] In an embodiment of the present invention, the dishwasher comprises a first movement
motor and a first rack mechanism which are connected to the first door, and a second
movement motor and a second rack mechanism which are connected to the second door.
When the storage unit completes its rotation, the first movement motor is energized
and the first door is opened by means of the first rack mechanism. When the tablet
passing through the first door reaches the chamber, the second sensor is triggered,
which in turn triggers the second movement motor. By means of the energy provided
by the second movement motor, the second rack mechanism transmits the movement to
the second door so as to open the second door. Thus, the tablet detergent is delivered
from the storage unit into the washing tub.
[0014] In an embodiment of the present invention, the dishwasher comprises an opening which
is provided on the door and a channel which extends from the opening to the filling
opening. This enables the user to deliver the tablet detergent directly to the detergent
dosing unit over the door.
[0015] By means of the present invention, a dishwasher is realized, comprising a detergent
dosing unit which automatically delivers the tablet detergent into the washing tub.
