Description

Description
A WASHING MACHINE COMPRISING A WASHING AGENT DISPENSER
[0001] The present invention relates to a washing machine comprising a washing agent dispenser.
[0002] In washing machines, for example in laundry washing machines and dishwashers, the washing agent required for the cleaning process is placed in a washing agent dispenser. The water received from the water inlet is directed inside the washing agent dispenser. The dissolved - melted washing agent passes into the washing tub together with the water. The washing agent dispensers generally comprise partitions wherein powder and/or liquid washing agents are placed and at least one water inlet for delivering water into the partition.
[0003] Mold is formed in the partition and the interior of the water inlet by time since the said partition and water inlet stays wet after the washing. Since mold is a form of life with spores it can survive in environmental conditions except at high temperatures. This condition is unfavorable in terms of hygiene. Moreover, these parts staying wet causes the washing agent used in the next washing to become damp and lumped thereby making it difficult to be delivered into the tub with the wash water.
[0004] On the other hand, when low temperature (30-40 C) washing programs are selected for the washing process, the detergent cannot be dissolved entirely since the solubility of the washing agent depends on the heat and the washing performance becomes worse as compared with the high temperature programs.
[0005] Another problem encountered as a result of the washing agent dispenser and the water inlet staying wet is that when the weather is very cold, the water in these sections freezes thereby adversely affecting the effectiveness of the washing machine.
[0006] In state of the art washing agent dispensers, resistant heaters are disposed inside the washing agent dispenser for heating the washing agent dispenser thereby eliminating the above cited problems.
[0007] In the state of the art Japanese patent application no JP3247394 a detergent container is explained which is heated by resistant wires disposed on its rear wall.
[0008] In the state of the art Japanese patent application no JP6190187, in a washing machine, a detergent storage part is explained which stores the washing agent and forwards it out by a coil mechanism driven to rotate by a motor. In this implementation, the coil used in the mechanism is allowed to function also as a heater by delivering electric current there through.
[0009] In these implementations known in the technique, the resistant heaters necessitate making an electrical connection to the washing agent dispenser. This condition makes the use of the washing agent dispenser difficult for the user in implementations wherein the dispenser is slid able and/or dismountable for loading and cleaning. On the other hand, the resistant heater disposed on a surface of the washing agent dispenser, for example the rear wall, heats the near vicinity effectively whereas the other parts of the washing agent dispenser are heated less and the desired dryness cannot be maintained.
[0010] The aim of the present invention is the realization of a washing machine comprising a washing agent dispenser whereof the hygienic and utilization features are improved.
[0011] The washing machine realized in order to attain the aim of the present invention is explicated in the attached claims.
[0012] The washing machine of the present invention comprises at least one conductive member situated on the walls of at least one of the compartments of the washing agent dispenser wherein the washing agent is put and at least one induction means, disposed in the housing wherein the washing agent dispenser is disposed, for heating the washing agent dispenser by inducting the conductive member. When current is delivered to the induction means, the conductive members are heated by being inducted and thus the inside of the compartment is dried and the microorganisms, if any, are exterminated. A physical connection is not present between the conductive members and the induction means. Accordingly, the washing agent dispenser is not prevented from being moved or dislodged for loading washing agents.
[0013] The washing machine comprises conductive members arranged around the water inlet for delivering water to the compartment. Thus, the problems of molding, freezing etc. are prevented in the section containing the water inlet.
[0014] In an embodiment of the present invention, the induction means is configured of wires and wound to surround the walls of the housing. Consequently, the entire washing agent dispenser can be heated with equal effectiveness.
[0015] In an embodiment of the present invention, the conductive member is placed into the mould during the production of the washing agent dispenser by plastic injection method etc. Thus, the washing agent dispenser is produced with the conductive members directly integrated on the compartment walls. Accordingly, an additional operation for mounting the conductive members on the compartment walls is not required.
[0016] The washing machine furthermore comprises a control unit for controlling the energizing of the induction means.
[0017] In an embodiment of the present invention, the energizing of the induction means is controlled by the user. In this embodiment, the washing machine comprises a selector that sends a command to the control unit that the user wants the induction means to be energized when actuated by the user. Consequently, the induction means is enabled to be operated at the time desired by the user and within the knowledge of the user.
[0018] In another embodiment of the present invention, the control unit automatically performs the energizing of the induction means at certain time intervals. For example, when a number of washing processes predetermined by the producer are performed, the control unit energizes the induction means at the end of the washing process. Consequently, the washing agent dispenser is heated regularly and preserved in a hygienic condition.
[0019] In an embodiment of the present invention, the washing machine comprises an alerter. When energy is delivered to the induction means, the user is notified by the control unit activating the alerter.
[0020] In an embodiment of the present invention, the washing machine comprises at least one lock that prevents the washing agent dispenser from being opened or dislodged by the user. While energy is delivered to the induction means, the user is prevented from dislodging the heated washing agent dispenser by the control unit activating the lock. [0021] The washing machine realized in order to attain the aim of the present invention is illustrated in the attached figures, where: [0022] Figure 1 - is the perspective view of a washing machine. [0023] Figure 2 - is the schematic view of a washing agent dispenser in an embodiment of the present invention.

[0037] In an embodiment of the present invention, the induction means (8) is laid on the walls of the housing (6) such that the washing agent dispenser (3) is helically surrounded (Figure 4). Consequently, every region of the washing agent dispenser (3) can be kept dry effectively by inducting the conductive members (7) disposed in the walls of the washing agent dispenser (3).
[0038] In an embodiment of the present invention, the conductive members (7) are placed inside the mould during the production of the washing agent dispenser (3) and thus at the end of production, a washing agent dispenser (3) with the conductive members (7) embedded within the walls is acquired (Figure 2). Accordingly, the user does not have contact with the conductive members (7) while the washing agent dispenser (3) is being cleaned by taking out of the washing machine (1).
[0039] The washing machine (1) furthermore comprises a control unit (9) that controls the energizing of the induction means (8).
[0040] In an embodiment of the present invention, the washing machine (1) comprises a selector (10) which sends a command to the control unit (9) for energizing the induction means (8) when actuated by the user. When the selector (10) is actuated by the user, the conductive members (7) are heated and hence the washing agent dispenser (3) is dried by energizing the induction means (8).
[0041] In another embodiment of the present invention, the control unit (9) energizes the induction means (8) at the end of the washing process when a number of washing processes predetermined by the producer is performed. Accordingly, the washing agent dispenser (3) is heated at certain time intervals and the existing organisms like molds are exterminated as a result of the high temperature.
[0042] In an embodiment of the present invention, the washing machine (1) comprises at least one alerter (11) which is activated by the control unit (9) while energy is delivered to the induction means (8) and notifies the user that energy is being delivered to the induction means (8).
