Definitions

  • the invention relates to a metering device for treatment agent for a washing machine, with at least two storage containers for receiving a respective treatment agent such as detergent or washing or rinsing additives, and a conveyor, with which the treatment agent can be promoted via a connecting hose to the washing machine.
  • a respective treatment agent such as detergent or washing or rinsing additives
  • the invention further relates to a washing machine, comprising a tub for receiving washing liquid and a control device, with a metering device, which can be arranged away from the washing machine, which is connected via two hose lines to the washing machine and is in operative connection with the control device of the washing machine.
  • the detergent In home washing machines, the detergent is usually added by hand to a chamber, which is rinsed with water into the tub after the start of the wash program.
  • the user must comply with the dosing instructions for the detergent used in each case and make sure that he fills the correct amount in the chamber.
  • automatic metering devices are used in which a larger amount of detergent is stored in a reservoir. When starting a washing program, the preset amount of detergent is then supplied to the washing liquid, so that the user does not have to pay attention to the amount of detergent to be filled in each wash cycle. Especially with commercially used washing machines such dosing devices are often used.
  • the metering device comprises a separate housing in which two storage containers for the adding means are permanently installed and a control device and the metering pump are accommodated.
  • water passes from the tub into the metering device, in which water the adding agent is added.
  • the added water with the admixing agent is pumped into the washing machine via a second line in the area of the flushing channel for the fresh water inlet.
  • the metering device disclosed here is designed as a separate Beistell réelle for which an additional fixed predetermined place must be provided laterally next to the washing machine.
  • a connection of the metering device to the washing machine via two hoses or pipes and a cable to power the Pump and for signal, - or data transmission.
  • the accessibility to the containers for filling or cleaning is hampered by the cramped arrangement.
  • Another metering device for liquid additives is from the DE 10 2005 050 083 A1 known.
  • a storage container for liquid detergent outside the washing machine is arranged and connected by means of a hose to the washing machine.
  • the metering pump is arranged, which promotes the liquid or viscous detergent via a hose into the lower region of the tub.
  • the metering pump is controlled by the control device of the washing machine, which determines the respective quantity of detergent to be metered on the basis of the switch-on time.
  • a metering device for powdered detergent known. From a reservoir, the washing powder is introduced into a mixing chamber and conveyed from there to the washing machine. An agitator comprising at least one rotating knife moves the powder within the container, the powder trickling through the movement through an opening into the mixing chamber. If the desired amount is present in the mixing chamber, the mixing chamber is rinsed with water, wherein the effluent, mixed with the washing powder water is passed through a line to the washing machine. In this metering device liquid detergent can not be used.
  • a metering device for liquid additives for a dishwasher known.
  • the liquid treatment agent is metered or admitted by means of a pump into the treatment room.
  • the metering device comprises a base part into which a plurality of storage containers are inserted.
  • another base part is provided which has an additional water supply, so that the powder can be mixed with the water and then pumped to the dishwasher.
  • This metering device has the disadvantage that it is suitable either only for liquid treatment agent or only powdered treatment agent.
  • a metering device for which a separate base part is provided for each storage container, which is in each case connected with a separate line to a distributor.
  • Several washing machines can be connected to the distributor, so that the selected adding agent is fed to the requesting washing machine.
  • the invention is thus based on the object of improving a metering device or a washing machine in such a way that it is suitable for a large number of types of detergents or treatment agents.
  • the advantages attainable with the invention are that the comfort is increased and the reliability for the washing results is improved.
  • the user no longer needs to estimate the amount of detergent at each wash and to fill by hand into a compartment of the Ein Albanykastens.
  • Another advantage is that the user can continue to use his preferred type of detergent and that the most suitable laundry detergent is used for the majority of laundry to be washed.
  • the metering device according to the invention is therefore designed so that both liquid treatment agent, such as colored laundry detergent or fabric softener and powdered detergent (powder, granules or beads) can be used, so that almost all washing cycles can be covered in a household.
  • it comprises a base unit, on which the reservoirs are removably mounted and fixed, wherein the conveyor is arranged in the base unit, which is provided for both powdered and liquid treatment agent.
  • the conveying device comprises a drain pump and a mixing chamber for receiving the treatment agent to be metered, wherein the treatment agent introduced into the mixing chamber can be flushed out by means of inflowing water and conveyed to the washing machine with the drain pump.
  • the metering device can be set up optionally. Also, a list next to the washing machine or below is possible because it is ensured by the drain pump that regardless of gravity, the treated with treatment agent water enters the washing machine.
  • the metering device has at least one reservoir for pulverulent treatment agent with an agitator, which is coupled to an electric motor and can be driven by this, wherein the powdery treatment agent can be introduced via an opening in the mixing chamber.
  • the powder is made free-flowing and thereby transported through the opening in the mixing chamber, so that the predetermined amount is dosed as accurately as possible.
  • the metering device has at least one reservoir for liquid treatment agent and a pump which is coupled to an electric motor and driven by this, wherein the liquid treatment agent is conveyed into the mixing chamber by the pump.
  • the pump such as a peristaltic pump
  • the predetermined amount is timed promoted from the container into the mixing chamber, the dosage can be met very accurately.
  • the pump is attached to the reservoir for liquid treatment agent.
  • the assignment of the pump to the associated container for liquid processing agent is ensured.
  • a gear motor for driving the pump or the agitator.
  • a gear is coupled to the electric motor or designed as a unit to provide a higher torque at the output of the transmission.
  • the engine can be made small in size with less power, and the necessary torque for crushing caked powder or for conveying viscous adding agent is still provided.
  • the geared motor for the agitator and the geared motor for the pump are arranged in the base unit.
  • the engines each have a clutch on the transmission output, which provides the detachable connection with the agitator or the pump. In this way, the containers can be easily removed from the base unit, for example, to clean them.
  • the container or container type can be freely selected with the treatment agent to be used.
  • the metering device comprises two storage containers, wherein in the base unit optionally a storage container for powdered treatment agent and a reservoir for liquid treatment agent or two reservoirs for powdered treatment agent or two reservoirs for liquid treatment agent are attached and attached. As a result, the user is provided with a multiplicity of possible combinations for equipping the metering device.
