Definitions
- the present invention refers to a method to determine the quantity of clothes and the type of fabric introduced in a laundry washer, and a laundry washer implementing such a method.
- Said information may be transmitted to the laundry washer control-system directly by the user, through appropriate means (such as keyboards with display, indexed knobs, keys, etc.), or can be automatically obtained by the control system itself, when the latter is technologically appropriate to this purpose (e.g. including an electronic microprocessor control system).
- the measure of the quantity of clothes and the type of fabric can be performed either directly or indirectly.
- a direct measurement method appears stricter but difficult to implement, as some sophisticated and expensive sensors are required, whereas an indirect measurement method better complies with the low-cost and moderate accuracy requirements as demanded by a commercial laundry washer.
- Said methods are based on the physical capacity of fabrics to absorb water, according to a procedure based on their quantity and fibre type.
- German patent application DE-A-4.122.307 discloses an indirect measurement method as mentioned above.
- the control system of a laundry washer elaborates the data information supplied by an electromechanical level sensor (pressure switch) during the initial phases of a washing cycle; such data information relate to the water level restoring process in the washing tub of the laundry washer.
- an electromechanical level sensor pressure switch
- FIG. 1 shows the main figure of said application DE-A4.122.307; said Fig. 1 shows a diagram indicating the water level in a laundry washer tub as a function of time.
- the axis of ordinates show some phases of water inlet into the machine tub, indicated by t1 and tk , and some phases of water absorbion by the laundry, indicated by ts .
- a quantity of water preset by the manufacturer is introduced through a proper solenoid valve into the machine tub, while the drum is at standstill; upon reaching the preset working level NA (i.e. the full level), the pressure switch trips causing said water inlet solenoid valve to close.
- NA preset working level
- This second phase occurs during a time interval ts1 , whose duration provides a measurement of the water absorption capacity by the laundry and consequently by the type of laundry.
- the pressure switch Upon reaching the level NE , the pressure switch reacts, so causing the water inlet solenoid valve to open; therefore, during the subsequent time interval tk , water will be topped up in the washing tub to reach the working level NA ; upon reaching it the pressure-switch will react again, causing said solenoid valve to close.
- the number of top-ups, or the sum of top-up times tk represents a measurement of the quantity of clothes introduced into the laundry washer.
- the method described above has two main problems :
- the method according to the present invention allows to overcome the two problems related to the cited known art, due to the fact that it is independen from the characteristics of the level sensor being used and is based on the concept of a "forced restoration" of the water level, as it will be better explained later.
- the method according to the present invention develops through the following five phases shown in Fig. 2 by their time intervals indicated with T1 , T2 , T3 , T4 and T5 respectively.
- water is supplied into the laundry washer tub for a fixed time T1 as imposed by the machine control system.
- said time T1 allows the introduction in the tub of an appropriate water quantity, which is below the one related to the final working level ( full level); in particular, said water quantity indicated with " a " in Fig. 2, equals a fraction (eg. 1/2 or 2/3) of the quantity related to the final level and, in any case, is such to allow the laundry to be wetted, without however that the same is fully immersed in the water.
- the level sensor of the laundry washer is "by-passed" by the electronic control system of the machine.
- Said water inlet takes place while the laundry-washer drum is at standstill.
- the laundry-washer drum is constantly rotated at a fixed speed for a preset time T2 .
- the water level in the tub gradually decreases due to the water absorption by the clothes.
- Time T2 is conveniently selected as a function of the machine geometry, i.e. as a function of the tub and drum characteristics, so as to warrant the required contact between the water supplied in the tub and the fabric contained in the drum.
- the level sensor of the laundry-washer according to the present invention is in fact "by-passed" by the control system.
- the drum is at standstill and the water inlet in the tub is completed up to the fixed level (indicated with “ c " in Fig. 2) related to the full condition of the level sensor in the laundry-washer (therefore the full level will be detected by the level sensor, which is enabled during this phase).
- the machine control system will then execute the counting of time T3 , as required for this purpose.
- the value of the ratio T3 / T1 (multiplied by an appropriate experimental coefficient K , which takes the machine geometry into account) is in relation with the water absorption speed by the fabric inside the laundry-washer drum, thus allowing the machine control system to identify the type of such fabric, on the basis of experimental reference data previously stored in permanent memory means contained in the control circuit itself.
- the control system will cause the drum to rotate again at a constant speed for a preset time T4 long enough ( T4 > T2 ) to warrant that the water absorption is proportional to both the quantity of clothes and type of fabric (this latter data information being already obtained by the control system at the end of previous Phase 3).
- time T4 is adequately selected as a function of the machine geometry without taking into account the characteristics of the level sensor.
- the only condition being required is that at the end of the fourth phase the level sensor have left the full level and is in the socalled empty level condition, which is required for completion of the fifth phase.
- the hystheresis of the level sensor is equal to a water quantity being not over about a liter of water, a condition which can be easily obtained for any type of level sensor available in trade.
- the fourth phase is a phase with a preset time.
- the water inlet is completed up to the fixed level related to the appropriate sensor ( full level) with the drum at standstill and the relevant time T5 required to this purpose is measured.
- T5 jointly with the ratio T3 / T1 (indicating the fabric type) provides a good evaluation of the quantity of clothes contained in the laundry-washer.
- the water inlet process Upon completion of the fifth phase, i.e. after the control system of the machine has determined both the quantity of clothes and the type of fabric, the water inlet process goes on in the usual manner (i.e. normally using the level sensor) till it reaches saturation, according to the inlet procedure which is typical for the type of level sensor being used. Said procedures, as mentioned, are apart from this invention.
- both the restoration and water absorption phases are always started by the response of the pressure-switch, when crossing preset thresholds (called NA and NE ), but the start instant is considerably affected by the sensor physical and manufacturing characteristics (specifically the hystheresis), so that the measurements are often unreliable.
- the time required to complete the measurement phase may be considerably long, due to the progressive extension of the absorption times tS , as the clothes become gradually saturated with water, and to the non-determinability of the required number of top-up/absorption cycles.
- the method being the object of the present invention is fully independent from the characteristics of the level sensorand the total time required is restricted and exclusively a function of the values T3 and T5 .
- the method of an indirect measurement of the quantity of clothes and of the fabric type in a laundry washer being the object of the present invention is based on the following conditions, which can be easily complied with:
- the first condition is warranted by the flowrate self-setting characteristics being typical of the solenoid valves presently used for household laundry washers.
- the second condition is always verified, being required for the water level control inside the laundry washer. It is independent from the type of the adopted level sensor, which may then be a conventional pressure-switch or an optical sensor (i.e. based on liquid refraction) or still a conductivity sensor or a solid state pressure sensor, etc.
- the third condition fully agrees with the control system evolution in the field of household appliances, favoured by the increasing availability of low-cost microcontrollers.
- control technology based on fuzzy logic, widely used by now in the consumers' application field, in particular in the household appliances field.
- the evaluation of the quantity and type of clothes will then be executed using experimental data adequately codified in a permanent memory being comprised in the control system, since the latter, as previously mentioned, will be based on a microcontroller.
