• a detergent drawer that provides the transfer of said washing agents to the washing tub after being mixed with washing water, is used.
• the object of the present invention is to provide and realize a washing machine comprising a detergent drawer that allows effective transfer of the washing agents contained in the drawer to the tub in such manner that all residual washing agentsare removed from the compartments containing them.

• Fig. 10 is the schematic view of the drawer recess. The components shown in the figures have individually been enumerated as shown below:
• the washing machine comprises a front panel (9); a washing agent drawer (2) which contains washing agents wherein said washing agent is mixed with the washing water; a drawer recess (1) into which said washmg agent drawer is placed and a water distributor (8) that directs the water entrained towards said washing agent drawer (2).
• the washing agent drawer (2) comprises one or more washing agent compartments (3) that receive the washing agent which contribute the washing performance, and one or more water ducts (4) that transfers water required for entraining the washing agent so that it mixes before reaching the tub.
• the washing agent compartment (3) has a width of which decreases downwards on the vertical axis with regard to the ground, such as a reverse conical or pyramidal structure.
• the bottom of the compartment (3) has a geometry that is narrower when compared to its inlet.. Therefore, when washing agent is introduced into washing agent compartment (3) said washing agent spreads by its own weight in said compartment (3) and the user is no more required to spread it manually and furthermore by virtue of this structure, only a small portion of the washing agent, not all of the agents, can be mixed with water and transferred to the tub.
• a certain number of compartments (3) are provided for the purpose of using different washing agents in the same machine.
• the water duct (4) is preferably situated at the rear wall of the said detergent compartment (3).
• the water duct (4) which is equipped with an inlet (5) and an outlet (6), has preferably a curved structure that prevents the washing agent from passing from the compartment (3) to the washing tub before being mixed with water and supports the mass of the washing material from below.
• Its inlet (5) is preferably connected to the water distributor (8).
• its outlet (6) is provided at bottom of the washmg agent compartment (3), opening to a point higher than its bottom.
• a passage (7) is formed by leaving a gap between the outlet (6) of the water duct and the bottom of the washing agent compartment (3).
• the washing agent particles that are mixed with water at the bottom of the washing agent compartment pass through said passage (7) to be transferred to the washing tub.
• the water distributor (8) is mounted to the drawer recess (1) in such a manner that water may be transferred both to the water duct inlet (5) and over the washing agent compartment (3). Said water distributor (8) is connected to the hoses that provide the hot and/or cold water circulation.
• the water distributor (8) itself is also equipped with channels (15) of various shapes and dimensions for the circulation of hot and cold water separately and for its transfer to the compartment (3) and/or water duct (4).
• one or more recesses (11) and pins (10) are provided on the drawer recess (1) and one or more projections (12) are formed so that they fit into said recesses (11) and one or more curved openings (13) for receiving the pins (10) and facilitating their movements are provided on both lateral sides of the drawer (2).
• the washing agent drawer (2) rotates around the axis which is assumed to be the line connecting the projections (12) and the pins (10) move inside the openings (13) formed on the washing agent drawer (2) while opening or closing said drawer (2).
• the rotational movement of the drawer (2) is limited by the dimensions of the opening (13) and the drawer (2) is in an inclined position when it is opened.
• This movement of the drawer (2) provides both a facility for its opening or closing and avoids the washing agent introduced into the drawer (2) to be poured out when it is in an inclined position, through the passage (7).
• Water first gets into contact with the small amount of washing agent present at the bottom of the compartment (3), then splashes against the surface opposing the said outlet (6), which is preferably curved and create a turbulence, passes through the passage (7) after mixing with the washing agent and is transferred into the washing tub. Meanwhile, as the water and washing agent mixture is transferred to the tub by passing through the passage (7) without reaching the upper sections of the washing agent compartment (3), residual washing agent particle accumulation at the inner walls of the washing agent compartment (3) is avoided. At the same time, the washing agent particles on the top of the stack of washing agent take the place of the particles transferred to the tub under the influence of the gravitational force, are transferred to the washing tub after mixing with the water from the water duct (4).
• the washmg agent contained in the washing agent compartment (3) only partially contacts with water, and the portion that has first contacted with water is directed towards the washing tub, thus avoiding the solidifying of the replacing washing agent due to wetting.
• This process continues as long as water, coming from the water duct (4) is directed towards the bottom of the washing agent compartment (3).
• the residual washing agent built up on the walls of the washing agent compartment (3) are removed and added to the washing liquid, in other words the most efficient mode of utilizing the washing agent is provided.
• Water may be directed to the washing agent compartment both from the bottom and the top either simultaneously or with a certain phase difference.
• water is supplied only from the top.
• the height of the side of the water duct (4) that forms the back wall of the washing agent compartment (3) that is adjacent to the said compartment is decreased.
• overflowing from the compartment (3) passes over said low side into the water duct (4) and is directed towards the bottom of the washing agent compartment (3).
• the water distributor (8) above the washing gent drawer (2) is provided with a directing member (16) in the shape of an umbrella with dimensions in conformity with the inlet mouth width of the said compartment (3) below the part above it. Water from the hole flows over the walls of the washing agent compartment (3) as a thin film of water from the surface of the directing member (16) in order to remove the residual washing agent particles.
• a propeller (14) with blades is placed in the water distributor (8) and the water, which is transferred to the washing agent compartment (3) by rotating the propeller by means of water pressure, cleans the walls.
• the propeller (14) provides the contact of all wall of the washing agent compartment (13) with water by the water coming out of the holes at different angles, formed on its periphery.
• two propellers with different angles, sections and dimensions of the blades are superimposed.
• Water passing through the blades of the upper propeller (14) splashes against the blades of the lower propeller and is directed in an irregular way, towards the walls of the washing agent compartment (3).
• perforations of various widths and angles are formed on the part of the water distributor (8) that is located above the washing agent compartment (3), so that water is transferred inside and to the walls of the washing agentcompartment (3) by a sprinkling method.
• water duct (4) is placed at the lower part of the washing agent compartment (3).
• the bottom of the washing agent compartment (3) opens to the water duct (4) and there remains no need to form a passage (7) between the rear wall and the bottom surface.
• the washing agent contained in the washing agent compartment (3) mixes directly with the water in the water duct (4) and is entrained into the tub.
• the washing agent drawer (2) is made of a transparent material so that the user may control whether the washing agent is taken in or not, without opening the drawer.
• main washing and pre-washing procedures are performed in one compartment (3) by controlling the level and duration of the water flow into the washmg agent drawer (2). In this case a decrease in such requirements as space and the number of values is attained.
