Definitions
- the invention relates to a washing machine, in particular a household washing machine a program selection device for selecting washing programs, which different Types of laundry are assigned, with a tub, in which a drum is rotatable is stored, with a detergent dispenser with at least one compartment for receiving of detergent, with a device for determining the weight of those in the drum Laundry, and with a microprocessor control to calculate a weight of the laundry-dependent set amount of detergent for the respective washing program.
- detergents are added to washing machines according to the instructions of the manufacturer on the respective detergent package, possibly with the help of a measuring cup.
- the dosage is ultimately left to the discretion of the user and therefore inaccurate. According to statistical studies, overdoses usually occur.
- an adjusting device is known with which the receiving volume a dosing chamber for detergents or dishwashing detergents can be changed.
- This Actuator consists of an elastic membrane and a connecting rod connected to it. The rod is guided into the operating area of the household appliance so that the Users by inserting or pulling out the volume as they see fit the dosing chamber and thus the respective amount of detergent / detergent can. In the end, this device also leads to a dosing by the user was determined at its own discretion and may therefore be incorrect.
- an automatic one is particularly useful in dishwashers, but also in washing machines Dosage of constant amounts of detergent known.
- GB 2 087 438 B also proposes as an alternative, one of the weight of the To carry out laundry-dependent automatic dosing of the detergent.
- An automatic Dosage is satisfactory only possible with liquid detergents, which from But users are used relatively rarely. Also for automatic dosing expensive additional equipment necessary.
- the invention thus presents the problem in a washing machine of the type mentioned Type to facilitate the dosage of detergent for the respective wash cycle.
- a device for entering the type and / or specific density of the detergent used This will make the different densities of compact and normal detergents are taken into account.
- microprocessor control for a particular program stores the determined or entered value in a non-volatile memory and at Selection of the same program with the program selector again. hereby you only have to enter the type and / or specific density when using a new one Detergent can be entered.
- the washing machine (1) designed according to the invention has a tub (2), in which a drum (3) for receiving laundry (4) is rotatably mounted.
- the drive of the Drum (3) takes place via a motor, not shown in the drawings.
- the tub (2) is swingably suspended on springs (5) in the housing (6) and becomes Damping of these vibrations in the lower area by shock absorbers (7) compared to Supported base (8).
- the detergent / fabric softener required to carry out a washing program will be the Suds container (2) via a detergent dispenser (9) with connected connecting hose (10) fed. To do this, the user can select the desired substances Corresponding compartments (11) of a detergent drawer (12) can be filled. About an in the water supply, not shown, the entire subject at the beginning of of the respective program part in the tub (2).
- a microprocessor control is used to control the different washing programs (see Figure 2) provided, the signal lines (14) with various transducers and Controls is connected. It issues time and status-dependent commands via control lines (15) to various actuators (motors, valves, display elements ).
- a first weight sensor (16) with which the loading quantity of the drum (3) is determined can.
- a position sensor can be used in a known manner, with which the weight-dependent lowering of the tub is detected.
- Other weight sensors e.g. strain gauges or other methods to determine Art and / or load weight can also be used.
- Another weight sensor (17) is arranged on the detergent drawer (12) determines the weight of the actual amount of detergent filled by the user. This weight signal is also passed on to the microprocessor control (MC). Instead of this Weight sensor (17), a level sensor can be used.
- FIG. 2 shows the controls of the washing machine (1) in an enlarged form.
- Rotary selector switch (18) the program to be carried out for the washing process depending on Laundry type and temperature selected.
- Other additional functions are by push button switches (19) can be selected.
- You can use a "heavily soiled” button (not shown) Degree of soiling of the laundry can be entered.
- the microprocessor control (MC) stands via a control line (15) with a signal device in the form of an indicator lamp (20) in connection.
- Another input element is used to transmit the specific density of the used Detergent. Entry can either be done manually using a keypad (not shown) take place or via a barcode reader (21) via which the microprocessor control (MC) Reads information about the type of detergent from the packaging and depending on it retrieves value for the density from a first memory (SP 1).
- MC microprocessor control
- SP 2 first memory
- Sp 2 second non-volatile memory
- the user switches the device on by pressing the "On / Off" button (22). After that he fills the laundry (4) to be washed into the drum (3). Then use the rotary selector switch (18) the program to be carried out for the washing process depending on the type of laundry and Temperature selected. Additional functions can be set using the push button switch (19) become.
- the user Before the first program start in a type of laundry, the user must have a value for the Enter the specific density of the detergent used for this laundry (4). This value is stored in a non-volatile memory (SP 2) and the corresponding type of laundry assigned. In this way, the fact is taken into account that for different Textiles different detergents can be used. The specific gravity value will beyond the end of the program in the non-volatile memory (SP 2) registered, so that new entries are only necessary when changing the detergent.
- SP 2 non-volatile memory
- the microprocessor control now starts the washing program with a sequence Enter the detergent. Depending on the laundry weight and specific detergent density it calculates a target amount of detergent (in grams). Has the "Strong dirty "is pressed, the target amount for programs in which heavy detergents is used (cottons / colored clothes; mini) by 50% and in programs where Fine detergent is used (delicates ...) increased by 20%.
- the target quantity is now continuously compared with the weight of the actual amount of detergent filled in the compartment (11). If the actual detergent quantity reaches the calculated target quantity value, the indicator lamp will light up (20) activated and lights up. Overflowing can be indicated by a flashing signal become.
- an acknowledgment button (23) is arranged next to the indicator lamp (20).
- the sequence for entering the detergent must then follow the selected program be processed several times accordingly.
- the washing program can be carried out by pressing the "Start" button (24).
- Figure 3 shows a further embodiment of the invention.
- the microprocessor control (MC) provides this embodiment depending on the laundry weight and the selected laundry type the volume of the compartment (11) and thus limits the detergent input for the main wash.
- Devices in the other subjects (11b, 11c) with an analogous effect are possible.
- the detergent drawer is in at least one compartment (11) (12) arranged a scale (29), in which there is a next to each scale LED (30) is located.
- These LEDs (30) are in from the microprocessor control (MC) in Depending on the laundry weight and the selected laundry type controllable, so that User is given a filling aid.
