Abstract
Description
- The present invention relates to a method for estimating the load of clothes in a household tumble dryer, such dryer being provided with a contact band or strip for moisture measuring circuit. With reference to
figure 1 a known tumble dryer is composed by the following components: a rotating drum actuated by an electric motor aimed at containing a certain amount of clothes inside; a heating element that heats the air to be blown inside the drum according to a predefined number of heating power levels; an air channel that conveys air either outside the appliance (vented dryer) or to a condenser (condensing dryer); two temperature sensors that measure the air temperature before entering the drum and the air temperature at the drum outlet; at least a contact strip normally used to measure the conductivity or resistivity of wet clothes; an optional spray nozzle used, in some dryer, to spray water and/or chemical substances on dry clothes in order to refresh them; a control unit that is able to read the actual value of the temperature sensors and of the other available sensors, including the conductivity value of the clothes and it is able to store the values in some memory registers, actuate the motor driving the rotation of the drum, the heating element according to predefined power levels, and the other actuators eventually available; and a digital regulator calculated by the control unit that keeps the clothes temperature close to a predefined temperature setpoint by modulating the heater input power. - In the above kind of dryer it is important not only to monitor the conductivity of clothes versus time in order to determine the appropriate duration of the drying cycle, but it is also important to assess such conductivity value depending on the total load of clothes. In most dryers the conductivity target value (and therefore humidity target value) is chosen for a predetermined or average load size. This target value may not accurately reflect different load sizes. A solution to this technical problem is disclosed by
US-A-2008/0052954 which shows a drying algorithm that sets its target conductivity value by taking into consideration the influences associated with load size. The algorithm disclosed by such document is based on the comparison, after a predetermined fixed drying time has elapsed, of the actual measured voltage (across contact strips or the like) and a predetermined voltage limit, in order to assess whether a small or large load signal has to be generated within the central process unit of the dryer. This known method has the drawback of not providing reliable signals on loads due to the determination of a single minimum value of conductivity. Moreover this method can only distinguish between a large or small load signals, giving therefore only a very rough possibility of adjusting the drying cycle on the basis of load size. Then, in order to increase the reliability of such rough assessment, the above document teaches to check the load estimation value by comparing it to a load signal generated by monitoring air flow temperature, therefore increasing the complexity and cost of the estimation system. - It is therefore an object of the present invention to provide a method for estimating the load of clothes in a tumble dryer which overcomes the above drawbacks and which is more reliable and more accurate if compared to prior art. Another object is to improve the automatic termination of the drying cycle based on conductivity values of the clothes.
- These objects are reached thanks to the features listed in the appended claims.
- By monitoring continuously during time an electrical parameter linked to the degree of clothes dryness, for instance the area under the curve conductivity/time, slope of such curve, time interval between two predetermined values of dryness or delay time for reaching a predetermined dryness, it is possible not only to discriminate among different values of load sizes, but also to carry out such estimation also near the end of the drying process.
- Another advantage of the method according to the present invention is to allow the designer building an experimental relationship between conductivity target values and actual loads of clothes on the basis of input humidity target values chosen by the user.
- The method according to the invention can be used also in the so called refresh cycle where the clothes are loaded dry in the dryer drum. During the refresh cycle it is necessary to spray water and/or chemical substances in order to reach a fixed value of humidity. If the spray flow is constant the voltage signal shape, read by the strip of the moisture measuring circuit, is strictly related to fabric mass. A big load needs more time than a smaller one to achieve the same value of humidity content. The method according to the invention allows to exactly evaluating the amount of water and/or chemical used in a refresh cycle for each type of load (small, medium, big). This allows a water/chemicals/time saving.
- The gist of the present invention is to use not only the voltage value but also the information related to its change vs. time, i.e. slope, derivatives, integral, time gap and all other voltage signal shape characteristics.
- Further features and advantages of a method and of a dryer according to the present invention will become clear from the following detailed description, given by way of non limiting example, with reference to the attached drawings in which:
-
figure 1 is a schematic view of an air vented tumble dryer; -
figure 2 is a diagram showing how the voltage signal changes with time when a big load is put in the dryer and a refresh cycle is started; -
figure 3 is a diagram similar tofigure 2 and relates to a small load; -
figure 4 is a diagram showing the relationship between load size and time for reaching a predetermined humidity content; -
figures 5-8 are diagrams showing the relationships between different dynamic parameters linked to voltage signal and time during a refresh cycle, particularly the area under the voltage signal curve, the changing slope of such curve, the time gap between two predetermined voltage values and a delay time before a certain voltage value is reached; -
figure 9 is a diagram showing how the voltage signal (strip values) changes vs. time, particularly at the end of a drying cycle, allowing an accurate discrimination on the load size based for instance on time elapsed between two fixed DC or voltage value, such time being proportional to the load value; -
figure 10 shows an experimental diagram on a commercial dryer in which the voltage signal (strip values) is linked to actual measured humidity content according to four different tests, two with load of 7 Kg and two with loads of 1 Kg; and -
figure 11 is a schematic algorithm flowchart according to the invention. - With reference to
figures 2 and 3 referring to a refresh cycle, when the nozzle in the drum starts to spray water the moisture measuring circuit doesn't work; only when the humidity content (called MR - moisture retention - in the following) is higher than a certain value, the moisture measuring circuit works well. As a consequence this "delay time" is strictly related to fabric mass. Infigure 2 the "shape" of the curve voltage vs. time is typical of a big load, i.e. for instance of a load higher than 3 kg, while the one offigure 3 is typical of a small load, i.e. for instance lower than 3 kg. According tofigures 2 and 3 , by analyzing the voltage signal shape is possible to estimate the fabric load accurately and choose the most appropriate value to end the drying cycle. -
Figures 5 to 8 describe different relationships between fabric mass and voltage signal shape during a refresh cycle where water is prayed onto the clothes. Of course the same considerations apply to drying cycle too. Also in this case the voltage signal shape is strictly related to fabric mass but of course it decreases instead of growing up. - With reference to
figures 9 and10 , the voltage value is decreasing but the behaviour of big loads is different from the behaviour of small ones. Infigure 9 the time A or B elapsed between two fixed voltage values is proportional to a certain load, the shorter the time, the smaller the load. The experimental diagram offigure 10 shows how the method according to the invention can discriminate not only among different load sizes (and therefore not only between "low" and "high"), but also among different final humidity values requested by the user, linking for instance the voltage curve vs. ideal values for interrupting the drying cycle, taking automatically into account the preference of the user and actual load of clothes in the dryer. Infigure 10 it is clear how the strip conductivity threshold value for a certain target humidity of the clothes is strictly related to the actual load. Without a precise load assessment according to the present invention, there is the risk that for a small load the drying process is interrupted too early, therefore giving unsatisfactory drying results. - With reference to
figure 11 , the algorithm inputs are: - DC Value (moisture measuring circuit data, expressed in terms of duty cycle values of a voltage related signal)
- Spray status (the algorithm computation starts when the spray nozzle is open)
- Delta time (the algorithm computation can be stopped by time)
- DC Fixed value (the algorithm computation can be stopped by reaching a particular DC Value)
- The output data, obtained by any known shape analysis, could be compared using a look up table or a regressor approach. The final output is the fabric load estimation.
- A possible way to carry out the shape analysis according to the slope-concept (
Fig. 6 ) could be the following: - The subsystem "spray_start_values" set some parameters when the spray cycle starts;
- After a certain "delta_time" the subsystem "delta_time_values" evaluates the slope angular coefficient "delta_time_alfa".
