Definitions
- the present invention relates to a dishwasher that comprises a detergent dispenser.
- detergent dispensers are used that are generally mounted on the inside of the door.
- reservoirs are provided for emplacing the detergent and the rinse agent chemicals.
- the detergent emplaced in the reservoirs enables the dirt on the dishes to be dissolved and the rinse agent lowers the surface tension of water thus improving drying.
- the chemical substances used in the cleaning process can only be effective if activated at the right step.
- the detergent has to be added to water in the main washing step whereas the rinse agent and glass protection agent in the hot rinsing (second rinsing) step.
- each chemical is put in its container enabling these containers to be opened in the proper step for using the right chemical at the right time.
- the tablet shaped combined detergents named as “2 in 1" or “3 in 1”, containing more than one chemical, dissolving at different temperatures such as detergent, water softener, and rinse agent together pressed in layers dissolve with the mechanical effect of water jets during circulation when directly put in the washing environment.
- the rinse agent chemical contained in the tablet that melts at only high temperatures also dissolves and is discharged with the waste water at the end of the main washing step, thus no rinse agent is left to be used in the hot rinsing step.
- the aim of the present invention is the realization of a dishwasher comprising a detergent dispenser wherein a detergent tablet is emplaced and enabling the tablet to be dissolved controllably until the end of the washing process.
- a rectangular prism shaped tablet including detergent and rinse agent substances is emplaced in the detergent dispenser for cleaning the dishes and the tablet is dissolved controllably in the detergent dispenser enabling it to be used until the end of the washing.
- the chemical substances contained in the tablet that have to be used in certain washing steps are prevented from being discharged by dissolving before due time.
- the detergent dispenser used in the dishwasher comprises a reservoir inside which water circulating in the tub enters during washing, forming a detergent-water solution as the water contacts the tablet, and enabling the said solution to be delivered to the washing environment inside the tub, and a tablet holder holding the tablet suspended in the horizontal position from the ceiling of the reservoir and the lower portion of which is inside the reservoir with a bottom wall shaped like a grate or sieve allowing the water entering the reservoir to contact the lower surface of the tablet.
- the detergent dispenser furthermore comprises a lid that is mounted to the ceiling of the reservoir, covering the tablet in the tablet holder, preventing the water circulating in the tub and moving downwards by the effect of gravity from directly reaching the tablet and an inlet hole opening to the lower side of the reservoir, allowing the water circulating in the tub to enter the reservoir from the lower side and move upwards inside the reservoir acting on the lower surface of the tablet suspended from the ceiling of the reservoir.
- the inlet hole under the detergent dispenser opens to the lower side of the reservoir to correspond opposite to the nozzle during the rotational motion of the spray arm.
- the inlet hole enables the water jet sent upwards from the nozzle to enter the reservoir in every turn or half turn of the spray arm and thus to contact the lower surface of the tablet intermittently and to dissolve the tablet gradually during washing.
- the detergent dispenser comprises a slot situated on the ceiling of the reservoir, surrounding partially or entirely the lid on the reservoir, enabling the water circulating in the tub to enter the reservoir from the top, washing the inner walls of the reservoir with water.
- the side walls of the detergent dispenser are shaped frustoconically and the water flowing into the reservoir from the slot washes down the inner surfaces of the inclined side walls, cleaning the detergent residues.
- the detergent dispenser comprises a barrier extending from the ceiling of the reservoir downwards, surrounding the tablet and preventing the water entering into the reservoir to reach the tablet from the side thereof.
- Figure 1 - is the schematic view of a dishwasher.
- Figure 2 - is the schematic view of a tablet detergent.
- Figure 3 - is the cross sectional view of a detergent dispenser.
- Figure 4 - is the perspective view of a detergent dispenser.
- Figure 5 - is the top view of a detergent dispenser.
- Figure 6 - is the top view of a detergent dispenser in another embodiment of the present invention.
- the dishwasher (1) comprises a tub (2) wherein the washing process is performed, a door for accessing into the tub (2), more than one basket (3) whereon items to be washed are emplaced, one or more spray arms (4) for delivering water onto the items in the baskets (3), more than one nozzle (5) disposed on the spray arm (4) for spraying water on the items by generating a water jet and a detergent dispenser (6) wherein a tablet (T) is emplaced.
- the tablet (T) used for cleaning the dishes is comprised of pressed layers containing the chemical substances of detergent, softener and rinsing agent and is preferably shaped as a rectangular prism.
- the dishwasher (1) of the present invention comprises a detergent dispenser (6) having
- a tablet holder (8) holding the tablet (T) suspended in the horizontal position from the ceiling (R) of the reservoir (7) and the lower portion inside the reservoir (7) with a lower wall shaped like a grate or sieve allowing the water entering the reservoir (7) to contact the lower surface (Y) of the tablet (T),
- a lid (9) that is installed to the ceiling (R) of the reservoir (7), covering the tablet (T) in the tablet holder (8), preventing the water circulating in the tub (2) and moving downwards by the effect of gravity from directly reaching the tablet (T) and
- the inlet hole (10) opens to the lower side of the reservoir (7) such as to correspond opposite the nozzle (5) during the rotational motion of the spray arm (4).
- the inlet hole (10) enables the water jet sent upwards from the nozzle (5) to enter the reservoir (7) in every turn or half turn of the spray arm (4) and thereby to contact the lower surface (Y) of the tablet (T) intermittently and to dissolve the tablet (T) gradually starting from the lower surface (Y) thereof during the course of washing.
- the washing program is started after the user emplaces the tablet (T) in the detergent dispenser (6), the spray arms (4) rotate and water is sprayed to the baskets (3) by means of the nozzles (5).
- the water jet entering into the reservoir (7) through the inlet hole (10) impacts on the lower surface (Y) of the tablet (T) and dissolves the tablet (T).
- the nozzle (5) comes opposite to the inlet hole (10) at every turn or half turn of the spray arm (4) and enables water to be sprayed into the reservoir (7).
- the mechanical effect of water is provided inside the reservoir (7) intermittently.
- the tablet (T) cannot dissolve "rapidly", instead dissolves gradually. Accordingly, the tablet (T) is dissolved controllably until the completion of the washing program.
- the detergent dispenser (6) is mounted to be suspended at the front side of the upper basket (3) and thus the user is enabled to easily reach the detergent dispenser (6) without bending too much ( Figure 1).
- the detergent dispenser (6) comprises a slot (11) situated on the ceiling (R) of the reservoir (7), surrounding partially or entirely the lid (9), and enabling the water circulating in the tub (2) to enter the reservoir (7) from the top, washing the inner walls of the reservoir (7) with water and dissolving the detergent residues to be added to the solution inside the reservoir (7) ( Figures 3, 5 and 6).
- the detergent dispenser (6) comprises a reservoir (7) having side walls shaped frustoconically that get narrower from the top downwards.
- the water flowing into the reservoir (7) from the slot (11) washes down the inner surfaces of the inclined side walls, cleaning the detergent residues ( Figures 3, 4).
- the detergent dispenser (6) comprises a reservoir (7) having side walls shaped frustoconically that get narrower from the top downwards.
- (6) comprises a barrier (12) extending from the ceiling (R) of the reservoir
