Description

150262

The present invention relates to an automatic detergent dispensing means and to the nature of the claim 5 mentioned in the preamble of claim 5.

Detergents are very hygroscopic and have the property of forming clumps when moist. Large detergent chunks may cause clogging in the dispensing arrangement of the machine. The best way to avoid lumps is to keep the detergent dry, and if this can be done, it is possible to portion it by an automatic means containing a small detergent storage so that it is possible to repeat a program a number of times. without manually loading detergent each time 15. I., the die means the bearing must be kept clearly separate from the wet cabinet of the machine.

US Patent No. 1,466,192 discloses a means for portionwise application of detergent to the washing machine washroom. In this case, the discharge opening is disposed over the laundry room so that the cleaning agent from a portioning room, by gravity, falls into the laundry room via a duct. However, during washing and rinsing, water droplets and vapor may enter the duct, causing the detergent to eventually collect on the walls of the duct, which may cause the duct to become clogged.

However, from French Patent Specification No. 2,386,966, it is known to place a fluid supply tube in the discharge port. Liquid from this pipe, which is directed towards the washing machine's washroom, sprays the walls of the drainage duct, it can be cleaned to prevent clogging of the duct.

It is an object of the present invention to further improve a metering means of the type mentioned above, which includes a fluid supply tube in the discharge port, with the particular purpose of completely emptying a current portion storage and rinsing it and the emptying duct completely and cleanly. optionally, any residual water in the compartment, which must then be refilled with detergent, as well as prevent steam and hot liquid from the laundry room from entering the storage for the powdered detergent.

This object is met by the fact that the initially mentioned dosing means is peculiar to that of the characterizing part of claim 1.

An embodiment of the dosing means is described below with reference to the drawing, in which 1 shows a vertical cross-section through the metering means, and FIG. 2 is a cross-section perpendicular to that of FIG. 1.

The metering means is located in the wet enclosure of a machine of the kind mentioned above, preferably in the door of the machine, which makes it easy to fill the organ when the door is open. A storage of detergent powder for yask or dishwashing is enclosed in a container 10 with a removable lid 11 having a seal 12 which is moisture resistant. The container is recessed on the inside of the door and only 25 lid is visible. The latter is preferably made of a transparent material so that you can see the amount of powder in the storage. Thus, it is easy to unscrew the lid and fill the container when necessary. At the bottom of the member there is a portioning member 14 designed to transfer a portion of the powder from the storage to the wet cabinet.

It includes a star-shaped roller 15, housed in a housing 16 by means of a shaft 17 and rotatable in the housing by a motor 18. In the roller there are a plurality of compartments 19 which are filled in a regular order during rotation 35 powder from the storage when any of these are in a feeding station constituted by a hole 20 in a wall of the container. The roller is driven by the motor 18 which is controlled by a program control mechanism not shown. The propulsion corresponds, at a slow speed of rotation, to an angular rotation at least equal to the width of the room. Each compartment passes during one revolution once past a discharge station in the form of a barrel opening 21 in the bottom of the housing 16, so that the powder / transferred by such a passing space is discharged through the dry housing opening and into the wet cabinet. The roller 15 runs along the inside of the housing, thus keeping the storage separate from the wet cabinet. This characteristic of the roller is improved by producing the roller of an elastic material. To further ensure the seal, a room filled with powder is always kept between the filling station and the emptying station. The powder absorbs any moisture that passes past the room wall from the emptying station, 15 To prevent water from being trapped in a room and being transferred to the storage room, the space next to the filling station is drained through a channel 22 and through the bottom of the housing.

To ensure emptying of the space at the filling station, a pipe 23 is located in the opening 21 and connected to the machine's circulation system. so that water splashes into the room and flushes it clean. The container 10 can be cleaned in a similar manner if needed. This is easily accomplished by unscrewing the lid 11 so that the container is open in the direction of the wet cabinet while allowing the machine to operate for a while.

The electric motor 18 is started from the program control mechanism in s-menB which keeps the motor running until a switch controlled 30 by a cam disk 24 cuts off the current to the motor. The cam is intended to control the switch to cause it to interrupt when a compartment coincides with the opening 21, thus achieving the most efficient emptying.
