Description of Invention

Washing devices such as washing machines used to perform the washing/rinsing/drying operations of items make use of washing fluids which can comprise cleaning agents such as detergents, softeners, etc.. to carry out these operations. Water and cleaning agents comprised in the washing fluid are supplied from their sources into the washing device and transferred to an inner chamber where items are present in order to carry out said operations. In order to perform said operations in an efficient manner, the washing fluid should contain an adequate amount of cleaning agents. Accordingly, the present invention provides a washer drawer providing a homogenous mixing of cleaning agents such as detergents, softeners etc. with mains water and the supply of the resulting mixture into the inner chamber where the items are present.
The washer drawer (C) according to the present invention, illustrated in Figures 1-4, is suitable for use in washing devices (not illustrated in Figures), which can be washing machines, comprising at least one inner chamber in which operations such as washing/rinsing/drying of items are performed, at least one door which provides access into the inner chamber, and at least one mains inlet line through which water from at least one water source is taken into the washing device, wherein said washer drawer (C) comprises at least one body (1) in which said cleaning agents are stored and which can preferably be moved to extend out of the washing device; preferably at least one handle so that the movement of the body (1) can be directed by a user; at least one water line (H) through which water from a source, e.g. municipal water system, is supplied into the body (1); at least one first compartment (1a) which is provided in the body (1) and in which a first liquid cleaning agent (e.g. detergent) is stored before a washing operation; at least one second compartment (1 b) which is provided in the body (1) and in which a second liquid cleaning agent (e.g. softener) used during a rinsing operation of items being washed is stored, and which preferably has a smaller volume than that of said first compartment (1a); at least one mixing compartment (1c) which is provided in the body (1), preferably between the first compartment (1a) and the second compartment (1b), and in which the first cleaning agent or the second cleaning agent is supplied and mixed with water from the water source; at least one mixing line (H3) of which at least one end is connected to the water line (H) and of which at least the other end is opened to the mixing compartment (1c); at least one first pump (P1) which is disposed on the body (1), preferably on an exterior side of the body (1), and allows to supply the first cleaning agent , preferably by dosing it (i.e. adjusting the amount), from the first compartment (1a) into the mixing line (H3); at least one second pump (P2) which is disposed on the body (1), preferably on an exterior side of the body (1), and allows to supply the second cleaning agent, preferably by dosing it (i.e. adjusting the amount), from the second compartment (1 b) into said mixing line (H3); and at least one first line (H1) situated between the first pump (P1) and the mixing line (H3), and at least one second line (H2) situated between the second pump (P2) and the mixing line (H3).
In an exemplary embodiment of the washer drawer (C) according to the present invention, the first cleaning agent is filled into the first compartment (1 a) and the second cleaning agent is filled into the second compartment (1b). While items in the inner chamber are washed, a determined amount of the first cleaning agent (detergent) is drawn from the first compartment (1 a) by means of the first pump (P1) into the first line (H1), and then transferred from here to the mixing line (H3). During the time the first cleaning agent is supplied to the mixing line (H3), water from the water source is also supplied to the mixing line (H3) through the water line (H). The first cleaning agent and water advanced through the mixing line (H3) and supplied to the mixing chamber (1c) are mixed into each other. Similarly, for example during the rinsing step of the items which were already washed, a determined amount of the second cleaning agent (softener) stored in the second compartment (1b) is drawn from the second compartment (1b) by means of the second pump (P2) into the second line (H2), and then transferred from here to the mixing line (H3). During the time the second cleaning agent is supplied to the mixing line (H3), water from the water source is also supplied to the mixing line (H3) through the water line (H). The second cleaning agent and water advanced through the mixing line (H3) and supplied to the mixing chamber (1c) are mixed into each other. By virtue of passing the cleaning agents (first cleaning agent and second cleaning agent) together with water through the mixing line (H3), it is ensured that the cleaning agents and water are homogeneously mixed and the mixture is passed through the mixing compartment (1 c) and then supplied into the inner chamber.
In an alternative embodiment as illustrated in Figure 2, the washer drawer (C) comprises at least one third compartment (1 d), which is provided in the body, preferably on the other side of the first compartment (1a) which is far from the second compartment (1 b), in which a third cleaning agent which may be a powder detergent is stored, and which comprises at least one opening (1 h) to let the third cleaning agent out of the washer drawer (C) (e.g. supply into the inner chamber). By virtue of the third compartment (1d), the washer drawer (C) can also be used in current washing devices using powder detergents.
In a preferred embodiment of the present invention illustrated in Figure 1, the washer drawer (C) comprises at least one top cover (1e) situated on an upper side of the body (1). In this embodiment, the top cover (1e) comprises, on an area corresponding to the top of the mixing compartment (1c) when it (1e) is placed on the body (1), at least one transfer area (1f) provided with a plurality of holes (1 g), wherein at least one end of said mixing line (H3) is connected to said transfer area (1f). Cleaning agent from the first line (H1) or the second line (H2) combines in the mixing line (H3) with water from the water line (H) and delivered together to the transfer area (1f). The mixture of cleaning agent and water is passed through the holes (1g) in the transfer area (1f) and poured into the mixing compartment (1c). Thus, a better mixing is ensured in the mixture as it is passed through the holes (1g). In an embodiment, the top cover (1e) comprises, on an area corresponding to the top of said third compartment (1d) when it (1e) is placed on the body (1), at least one transfer area (1f) provided with a plurality of holes (1g), wherein at least one third line (H4) in communication with a water source (e.g. municipal water system) is connected to said transfer area (1f). The third cleaning agent is filled into said third compartment (1 d) before a washing operation and water from the third line (H4) is poured through the holes (1g) provided in the transfer area (1f) over the cleaning agent present in the third compartment (1d). The mixture of the cleaning agent and water is let out of the washer drawer (C) through the opening (1h) provided in the third compartment (1d).
In a preferred embodiment, in order to prevent water or a mixture of water-cleaning liquid entering into the transfer area (1f) from leaking from the transfer area (1f) out of the body (1), the top cover (1e) comprises at least one lid (K) situated on the transfer area (1f). In case the lid (K) is placed on the transfer area (1f), sealing is ensured.
In another embodiment of the present invention, the body (1) comprises at least one first outlet (11a) providing communication between the first compartment (1a) and the first pump (P1). Similarly, in a further preferred embodiment, the body (1) comprises at least one second outlet (11b) between the second compartment (1b) and the second pump (P2), providing communication between the second compartment (1b) and the second pump (P2). In these embodiments, cleaning agents present in the first compartment (1a) and/or second compartment (1 b) are passed through the first outlet (11 a) and/or the second outlet (11 b) and delivered into the first pump (P1) and/or the second pump (P2). By virtue of the first outlet (11 a) and the second outlet (11 b), it is ensured to dispose the first pump (P1) and the second pump (P2) outside of the body (1). Thus, it is avoided that the electronic components generally present in the pump are placed within the body (1) which contains a liquid. Thus, a safe washer drawer (C) is obtained.
In another preferred embodiment of the present invention, the washer drawer (C) comprises at least one sensor (not illustrated in Figures) for measuring parameters like the amount, weight, amount of dirt etc. of items placed into the inner chamber, and at least one control element (not illustrated in Figures) for adjusting the amount of water and/or of the cleaning agent(s) (first cleaning agent, second cleaning agent) used in the washing and/or rinsing operation(s) according to the measured values. In a preferred embodiment, the control element is coupled to the first pump (P1) and/or to the second pump (P2) and/or to at least one main pump (not illustrated in Figures) feeding water into the body (1). In an embodiment in which the washer drawer (C) comprises a first outlet (11a) and a second outlet (11b) (in other words, in case the first pump (P1) and the second pump (P2) are disposed outside of the body (1)), the first cleaning agent and/or the second cleaning agent are filled into the first compartment (1a) and/or the second compartment (1b). Since the first pump (P1) and the second pump (P2) are disposed outside of the body (1), the body's (1) volume can store a greater amount of cleaning agent as compared to a drawer body comprised by known washing devices. Therefore, the cleaning agent filled into the body (1) can be used in more than one washing operations. In this embodiment, the first cleaning agent and the second cleaning agent are filled into the first compartment (1a) and the second compartment (1b), and the amount of water and/or of the first cleaning agent and/or the second cleaning agent fed into the mixing line (H3) in a washing and/or rinsing operation is adjusted according to the data received from said control element. Thus, although it is not required to add cleaning agent into the washer drawer (C) anytime a washing operations is started, any overuse of cleaning agent and water is avoided. Thus, an environmentally-friendly and economical washer drawer (C) is obtained.
The washer drawer (C) developed according to the present invention provides the storage of cleaning agents such as a detergent, a softener, etc. in washing devices, and further provides the mixing of the cleaning agents and water, which is supplied from a water source, in the washer drawer before washing/rinsing operations and then the supply of the resulting mixture into the inner chamber where said operations are performed. Additionally, the washer drawer (C) according to the present invention provides an automatic adjustment of the cleaning agents and/or water to be used according to the weight and/or the amount of dirty of items to be washed, and thus a washing device comprising said washer drawer (C) is rendered economical.
