Definitions
- the present invention refers to a clothes washing machine, particularly of the household type, provided with improved means for automatically determining the weight of the load of items to be washed.
- the present invention refers specially to clothes washing machines of the front-loading type, and for the sake of convenient exemplification the following description is actually referred to such a front-loading type of clothes washing machine, it will be appreciated that it may advantageously apply to other types of clothes washing machines as well, particularly to top-loading machines or machines having their drum rotating about an oblique axis.
- Clothes washing machines provided with means adapted to automatically identify the load of items to be washed are known in the art, wherein the term load, or washload, is used here and in the following description to solely mean the overall mass of the items to be washed, and not their nature or characteristics.
- the ability of the washing machine to recognize in an automatic manner each washload that is introduced in its drum for processing is a pre-requisite in view of the self-programming ability of the same machine, which will then be able to automatically define all of the parameters to be used in the washing process, such as the amount of detergent, the amount of water to be filled in, the number and the type of washing and rinsing phases to be performed, etc., so as to each time optimize the operation of the machine, while sparing the user the trouble of having to select each time the most suitable programme and in this way avoiding his or her quite frequently introducing in the process programming errors that prevent the machine from operating in optimum conditions.
- the measurement of the dry washload is performed by successively driving the drum holding the washload at two distinct, pre-determined speeds of rotation, while measuring both the time and the torque needed to reach the first one of said two speeds of rotation, as well as both the time and the torque needed to increase the speed of rotation of the drum from said first speed to a second pre-determined speed with a different motor torque.
- water is used to equally mean washing liquor or rinsing water.
- Such a simplification should not, however, affect the clearness and intelligibility of what is set forth in said description, owing to the context in which such terms are used, as anyone skilled in the art will readily appreciate.
- the described clothes washing machine comprises a washing tub 1, a drum 2 rotatably arranged within said washing tub and adapted to accomodate the washload 3, an electric motor 4 associated with said drum and adapted to drive it at variable, pre-selectable speeds of rotation.
- the washing machine is provided with a variable-speed motor and an arrangement adapted to deliver the information relating to the instantaneous speed of rotation of the drum (typically this is a tachometer, but any other device capable of delivering such an information would do for the job).
- appropriate devices capable of acquiring and delivering an information equivalent or corresponding to the output torque of the motor shall be provided accordingly.
- Such devices are generally known in the art and may be appropriately selected by those skilled in the art among the variety of existing solutions, such as for instance a peak-voltage detector and a phase-delay type motor control, or a circuit capable of integrating a current equivalent to the motor current, etc.
- a processing element (not shown) is further provided, in which following data are stored:
- the inertia of the washing machine without washload is determined automatically by the machine by performing the procedure under no load conditions, ie. without any washload introduced in the drum.
- a kind of self-calibration of each machine can in this way be performed so as to eliminate any manufacturing variable from the calculation of the weight of the washload.

Description
- Figure 1 is an exploded view reflecting the assembly sequence of a number of component parts which are of a fundamental importance to the purpose of the present invention, such as for instance the rotating drum, the driving motor and other auxiliary parts;
- Figure 2 is a diagram of the initial operation sequence of a washing machine according to the present invention.
- the stabilization speed,
- the length of the period of time in which said speed remains in its stabilized condition,
- the lowest and the highest speed limits defining the interval of observation of the speed during the natural slowing-down of the system,
- In the phase 1, the motor is energized to step up the speed of rotation of the drum, which has been previously loaded with the sole items to be washed, ie. without any water admission, from its zero value (at P1) to a predetermined value Vs at P2.
- Upon reaching said speed, the motor,in the subsequent phase 2, is automatically controlled during a certain time T1 so as to maintain said speed, and during this phase the torque needed by the motor to maintain such a speed constant is measured.
- In the subsequent phase 3, the drum driving motor is de-energized so that it slows gradually down due to the opposing action of inertia, which would tend to maintain the initial speed of rotation, and friction forces braking the whole of the rotating mass, thereby causing it to slow down.
- C =
- Torque
- A =
- Coefficient of constant friction
- B =
- Coefficient of friction linearly variable with the speed
- J =
- overall inertia as measured on the driving shaft
- T =
- reading period (sec. ) of the speed values during phase 3
- Vs =
- holding speed in phase 2
- K =
- generic moment of reading of angular speed where P1 and P2 are calculed on the basis of the historical series of speed values through the use of the least squares method, and whose mathematical justification is known to the skilled in the art.
Claims (3)
