Definitions

  • the object of the invention is a household appliance with circulating water, such as a washing machine or a dishwasher, having a dosing container for a manual system of laundry detergent metering and an integrated system for automatic laundry detergent metering.
  • the technical problem is how to conceive a household appliance with circulating water, such as a washing machine or a dishwasher, with a system for both manual and automatic laundry detergent metering that will allow for receiving the laundry detergent and/or laundry aids in one place regardless of the mode of laundry detergent metering and regardless of the type of the laundry detergent, wherein laundry detergent metering must be user-friendly and the manufacturing of such a household appliance must be economically justified.
  • Household appliances with circulating water, particularly washing machines for washing and laundry care, are nowadays often provided with systems that provide for automatic metering of a laundry detergent.
  • the automatic metering should supply an optimal quantity of a laundry detergent to the process of laundry washing and/or care depending on the parameters such as laundry detergent type, quantity and dirtiness of the laundry, water hardness, and selected washing programme. This type of metering is therefore ecologically more acceptable since a smaller quantity of a laundry detergent is consumed on average.
  • automated metering of a laundry detergent manual metering is still requested, in a conventional way through a dosing container, since many a user wants to have control over the operation of the washing machine and has specific needs, wishes and habits relating to laundry washing and care.
  • a dosing container that comprises a housing fixed within the washing machine, an extractable drawer arranged in the housing, and a cover/rinsing part that covers the drawer with the housing.
  • a dosing container is usually arranged on the front side of a machine to be easily accessible to the user.
  • the extractable drawer can be divided into several chambers intended to receive for instance a laundry detergent for the main washing cycle, pre-washing and care of the laundry.
  • the drawer with the chambers is configured to receive a laundry detergent either in a powder or liquid form.
  • These types of dosing containers are generally known.
  • the user puts/pours a laundry detergent manually into a chamber depending on the selected programme for laundry treatment. Dosing of a laundry detergent is left to the user who fills the dosing drawer with a laundry detergent before each washing.
  • Laundry detergent dosing in modern washing machines is carried out automatically through an automatic dosing system.
  • a liquid laundry detergent which is available in at least one special container is used in the automatic dosing system.
  • the container has a volume that can receive a considerable amount of a laundry detergent for several washing cycles.
  • the container is arranged within or outside a washing machine, such that the user can fill it or replace it with a new, full container.
  • When the container is arranged in the machine its shape is predetermined and only the prescribed shape can be used. Regardless of whether the container is filled or replaced, it is important that the container is arranged in an area easily accessible to the user and simple to handle.
  • EP 2478145 Al shows an automatic dosing system having only a dosing container for receiving two types of liquid laundry detergents that are dosed into the washing machine tub through an automatic dosing system. The user neither has a possibility to manually dose the laundry detergent nor a possibility to use a powder laundry detergent.
  • Washing machines with an automatic dosing system have a dosing container for manual laundry detergent dosing and an extra dosing container which stores a liquid laundry detergent in two containers of a certain shape and size.
  • the containers are arranged in the front, bottom part of the machine.
  • the containers must be large enough to be able to receive a sufficient amount of a laundry detergent for multiple automatic dosing, they can only be arranged closely to the bottom of the machine since there is no room for them elsewhere due to the shortage of space.
  • the user has access to the containers through a door arranged on the front side of the washing machine. If the user wants to replace the container or refill it, he must bend almost to the ground.
  • a solution from EP 2053154 Al is known, in which automatic dosing of a liquid laundry detergent is carried out in a way that an extra container with a liquid laundry detergent is inserted in one of the chambers, said container, by means of a special actuating system, then dispensing a certain quantity of the liquid laundry detergent into the dosing drawer and further into the machine tub.
  • a drawback of such an embodiment is elimination of one chamber of the dosing drawer because the extra container is inserted into the dosing drawer.
  • the laundry detergent quantity is also very limited.
  • EP2340326 Al discloses a dosing container with two compartments, wherein the first compartment comprises one chamber for receiving a powder laundry detergent for manual dosing, while the second compartment comprises two chambers, each receiving a different type of a liquid laundry detergent for the automatic dosing system.
  • the dosing container is preferably intended to receive a liquid laundry detergent in the automatic dosing system. If the user would like to use manual dosing, he can only use one type of a powder laundry detergent, the user cannot chose a washing cycle with prewashing and/or laundry softening and cannot use liquid laundry detergents since only one chamber is available. Because the space available in the dosing drawer is very limited, the chambers for receiving the liquid laundry detergent for automatic dosing are relatively small and need to be frequently re-filled.
  • the household appliance with circulating water of the invention includes a system for automatic laundry detergent dosing with a dosing container for receiving a laundry detergent in manual dosing, said dosing container comprising a housing, an extractable drawer arranged in the housing, and a cover part covering both the drawer and the housing, wherein the extractable drawer has more than one compartment for receiving a laundry detergent in a powder and/or liquid form and includes a chamber mounted on the external side of its bottom, and at least one compartment, preferably two compartments, that are in fluid communication through said mounted chamber with the automatic dosing system of the household appliance.
  • a fluid communication in the form of a tube is established from the container to the dosing container/dosing drawer.
  • the household appliance with circulating water such as a washing machine or a dishwasher, has an extractable drawer of a dosing container provided with at least one compartment for a liquid laundry detergent and/or laundry aids.
  • the compartment has a discharge opening in its bottom and at least one channel-like chamber mounted on the external side of its bottom and extending along same, said channel forming a fluid communication between an extra compartment and the automatic dosing system arranged within the household appliance.
  • the extractable drawer has two extra compartments arranged within the extractable drawer along its front side.
  • the compartments are closed by a swing door and have a discharge opening in their bottoms.
  • Each extra compartment is in fluid communication with one channel.
  • Each channel has an inner width that is proximal to the front side of the drawer and coincides with each discharge opening of the extra compartment, and an inner width which is distant from the front side of the drawer and leads into the discharge opening.
  • the bottom of the extractable drawer is inclined downwards towards the interior of the appliance.
  • the housing of the dosing container is provided at its front end with two discharge orifices with a tube connection for receiving a filling tube that connects the housing of the dosing container and the container for the liquid laundry detergent of the automatic dosing system.
  • the household appliance comprises a fluid communication of the liquid laundry detergent between the dosing container and its extractable drawer on the one hand and the container for the liquid laundry detergent of the automatic dosing system on the other.
  • the household appliance with circulating water of the invention allows for dosing the laundry detergent in one place regardless of the selected mode of dosing, i. e. manual or automatic dosing. Such mode of dosing is more user-friendly and simpler.
  • the user inserts all necessary laundry detergents into the appliance in one standard place of the appliance and the user does not have to bend.
  • the household appliance has a built-in automatic dosing system, the user can also use the laundry detergent manual dosing system without limitations for all washing cycles and with various laundry detergents and/or laundry aids in a powder and/or liquid form.
  • the user has a possibility of carrying out various methods of laundry washing/caring, which is made possible by the simple mode of laundry detergent manual dosing or by the automatic dosing method.
  • the dosing container and its extractable drawer are not formed as a container for the laundry detergent but merely as a component part of the fluid communication established between the dosing container and each laundry detergent container in the automatic dosing system.
  • the household appliance of the invention includes at least one laundry detergent container for automatic dosing, preferably two containers; it might include a plurality of them.
  • the two containers for the liquid washing detergent automatic dosing system can be arranged anywhere within the household appliance, preferably in a location with available space, and can be of any shape adapted to the available space. Since the containers are filled directly through the dosing container, the containers need not be directly accessed from the outside. This further means that the external front side of the appliance is not provided with any additional recesses that would call for additional technological operations and would have a negative impact on the aesthetics of the appliance.
  • the household appliance of the invention simplifies the manufacturing method.
  • the dosing container built in the household appliance of the invention allows single production regardless of the dosing system type. If only the system for manual dosing of the laundry detergent is used, practically the same method and minimal changes in the tools can be used to manufacture a dosing container for manual dosing of the laundry detergent only, in fact, this is yet additional economical issue which is in favour of the production of the household appliance of the invention.
  • the household appliance can be arranged at a wall and does not need any additional space for manipulation.
  • FIG. 1 Schematic view of a washing machine in cross-section
  • a household appliance 1 with circulating water such as a washing machine or a dishwasher, preferably a washing machine, has a tub 3 arranged in a housing 2 and a concentrically rotating drum 4 arranged within said tub for receiving laundry.
