Description
A DISHWASHER THAT IS PREVENTED FROM WASHING WITHOUT
DETERGENT
[0001] The present invention relates to a dishwasher which is prevented from washing without detergent.
[0002] In dishwashers the detergent dispenser in which the detergent is placed is situated on the side of the door facing the tub. In the detergent dispenser, a space wide enough for the detergent tablet to be fitted and a cover that closes the space are provided. The cover is a cover which opens towards the inside of the tub by rotating around an axis and the cover is closed after the tablet detergent is placed into the dispenser. When this cover will open during the washing program is determined by the control unit.
Generally, this cover is opened by the control unit 3-5 minutes after the washing program starts and the tablet detergent therein falls into the tub.
[0003] However, this cover cannot be opened completely from time to time
because of some obstructions that get in front of the cover. Generally, a utensil or cutlery that comes in front of the detergent dispenser causes this problem to occur. The cover hits these objects while opening and cannot be opened at all or cannot be opened completely. In this situation, the tablet detergent that is stuck between the detergent dispenser and the cover does not fall into the tub. As a consequence, the washing is performed without using detergent and the dishes washed are not cleaned as required thereby causing both unnecessary time and energy
consumption and also customer dissatisfaction. Moreover, there is the possibility of detergent particles remaining on the dishes when the washing program ends since the tablet detergent will not be entirely dissolved in the case the tablet detergent gets stuck between the detergent dispenser and the cover.
[0004] In the state of the art German Patent Application No DE10254089, a
dishwashing machine which comprises a sensor that detects whether or not the lid of the dispenser is completely closed is explained.
[0005] The aim of the present invention is the realization of a dishwasher which is prevented from performing washing without detergent that is caused when
the cover of the detergent dispenser is not able to open completely.
[0006] 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 sensor disposed on the cover of the detergent dispenser which detects the presence of an object that enters into the motion field of the cover. The control unit does not start the washing program if the sensor detects the presence of an object that enters into the motion field of the cover.
[0007] Thus, when an object in the motion field of the cover that will prevent the cover from opening completely is detected, washing without detergent is prevented by not starting the washing program.
[0008] In an embodiment of the present invention, the sensor is activated when the dishwasher is energized.
[0009] In another embodiment of the present invention, the sensor is activated when the start button is pressed and if an object entering the motion field of the cover is detected, the washing program is not started until the object entering the motion field of the cover is moved away from this field even though the start button is pressed.
[0010] In another embodiment of the present invention, the dishwasher comprises an alerter which gives the user audible or visual information about the presence of an object in the motion field of the cover. Consequently, the user can easily understand whether or not an object is present in front of the cover that prevents the cover from opening completely when the door is closed and, if there is an object in the motion field of the cover, the removal of this object is provided.
[001 1] By means of the present invention, the problem of the detergent dispenser cover not opening completely or the tablet detergent getting stuck between the dispenser and the cover is eliminated. Whether or not the cover will be opened completely is transmitted to the user by various warnings before the washing program is started thereby preventing the occurrence of a situation like the dishes not being washed without detergent.
[0012] A dishwasher realized in order to attain the aim of the present invention is illustrated in the attached figures, where:
[0013] Figure 1 - is the sideways view of a dishwasher when the door and the
cover are open.
[0014] Figure 2 - is the schematic view of a cover in the closed position.
[0015] Figure 3 - is the schematic view of the cover in the open position.
[0016] The elements illustrated in the figures are numbered as follows:
1. Dishwasher
2. Tub
3. Door
4. Detergent dispenser
5. Cover
6. Start button
7. Control unit
8. Sensor
9. Alerter
[0017] The dishwasher (1 ) of the present invention comprises a tub (2) wherein the items to be washed are placed, a door (3) providing access into the tub (2), a detergent dispenser (4) disposed on the surface of the door (3) facing the inside of the tub (2) when closed, wherein detergent in tablet form is placed, a cover (5) closing the detergent dispenser (4), providing the detergent to be transferred from the detergent dispenser (4) into the tub (2) when opened by rotating towards the inside of the tub (2) during washing and a control unit (5) that regulates the washing programs (Figure
1 ).
[0018] The dishwasher (1 ) furthermore comprises a sensor (8) disposed on the cover (5) which detects, by scanning the motion field (A) followed by the cover (5) while changing from the closed position to the open position, whether or not an object that can prevent the cover (5) from opening is present in that field. The motion field (A) of the cover (5) is the field swept while opening and closing rotatably (Figure 2 and Figure 3). When the door (3) is closed, the sensor (8) scans the motion field (A) of the cover (5) and if an object that prevents the cover (5) from opening completely by entering this motion field (A) is detected, the washing program is not started by the control unit (7).
[0019] Consequently, the problem of washing without detergent that can arise as
a result of the cover (5) not opening completely due to items such as tall plates, pans or tall cutlery projecting towards the front of the cover (5) is solved.
[0020] In the preferred embodiment of the present invention, the sensor (8) is a type of presence or position sensor which functions with optical or magnetic or sound signals.
[0021] The user, after loading the dishes in the tub (2) of the dishwasher (1 ), places the tablet detergent into the detergent dispenser (4) on the door (3) in the open position and closes the cover (5) of the detergent dispenser (4) and then closes the door (3). When the door (3) is closed, the sensor (8) scans the motion field (A) of the cover (5) and if an object entering this motion field (A) that prevents the cover (5) from opening completely is detected, the washing program is not started by the control unit (7) and the operation of the dishwasher (1 ) is prevented.
[0022] In an embodiment of the present invention, the dishwasher (1 ) comprises a start button (6). In this embodiment of the present invention, the sensor (8) is activated when the start button (6) is pressed. The washing program is started after the start button (6) is pressed and if the sensor (8) detects an object in the motion field (A) of the cover (5), the washing program is not continued and is stopped by the control unit (7). In this situation, the user is required to open the door (3) and rearrange the position of the object so that opening of the cover (5) is not prevented by the object entering into the motion field (A) of the cover (5). After the position of the object is rearranged so as not to enter into the motion field (A) of the cover (5), the door (3) is closed and the start button (6) is pressed. After the start button (6) is pressed, if an object in the motion field (A) of the cover (5) is not detected by the sensor (8), the control unit (7) resumes the washing program.
[0023] In another version of this embodiment, the sensor (8) is activated
whenever the dishwasher (1) is connected to the mains. If the sensor (8) detects an object in the motion field (A) of the cover (5), then the washing program is not started by the control unit (7) even if the start button (6) of the dishwasher (1 ) is pressed. In this situation, the user is required to open
the door (3) and rearrange the position of the object so that opening of the cover (5) is not prevented by the object entering into the motion field (A) of the cover (5). The door (3) is closed after the position of the object is rearranged so as not to enter the motion field (A) of the cover (5). The control unit (7) starts the washing program if an object is not detected in the motion field (A) of the cover (5) by the sensor (8).
[0024] In another embodiment of the present invention, the dishwasher (1 )
comprises an alerter (9) which informs the user about the presence of an object in the motion field (A) of the cover (5). Consequently, if the presence of an object in the motion field (A) of the cover (5) is detected by the sensor (8), the control unit (7) gives the information about the presence of an object in the motion field (A) of the cover (5) to the user by the alerter (9) with visual and/or audible warning.
[0025] By means of the present invention, in dishwashers (1) wherein tablet
detergent is used, the washing process is prevented to be performed without detergent which results from the cover (5) of the detergent dispenser (4) not being able to open completely and the tablet detergent not falling into the tub (2). Consequently, the user is warned at the start of the washing program and the washing program is allowed to be started after removal of the obstructions preventing the cover (5) from opening completely.
[0026] It is to be understood that the present invention is not limited to the
embodiments disclosed above and a person skilled in the art can easily introduce different embodiments. These different embodiments should be considered within the scope of the claims of the present invention, too.
