Definitions
- the invention relates to an improved type, particularly for domestic use, of a laundering or dishwashing machine provided with particular electric circuitry which, in association with timer of a specific type, permits various temperatures and various durations to be selected for individual operating phases without necessitating respective thermostats.
- thermogradual system for regulating the temperature of the laundering liquid bath, and operable to attain one or several temperatures by energizing the heater element over one or several defined periods of time, by a suitable construction and arrangement of the electric circuitry and the program control unit.
- this solution does not permit to accurately attain the optimum temperatures for a determined cycle, inasmuch as the final temperature of the bath depends not only on the time the heater element is energized and the rated output of the heater element, but also on the initial temperature of the laundering liquid, which is unknown and may vary within rather wide limits.
- thermogradual operation it would therefore be desirable, and is in fact the object of the present invention, to provide a washing machine in which the advantages of the thermogradual operation are enhanced by the possibility of selecting, amongst a number of predetermined durations, the desired duration of certain phases of the cycle, and amongst a number of predetermined temperatures, the optimum temperature for any particular type of laundry.
- this object should be attained without the necessity of a nearly totally new construction of the machine, so as to keep the production cost low and to not aggravate the complexity of the circuitry of the laundry washer as a whole.
- Appliances of this kind employ a single program control unit provided with two selector controls in the form of rotatable discs, a first disc acting directly on the control unit for the selection in the conventional manner of the desired laundering cycle, and a second disc acting on determined mechanic components contained in the program control unit and operable to vary in a continuous manner the rotary speed of the cam disc stack during certain phases of the operating cycle.
- control unit uses the same cams as employed for controlling the various phases of the laundering cycle, with the difference that these same cams now control the opening and closing of associated contacts at a different and regul-atable rhythm, permitting them to be employed for controlling the phases of the drying cycle known to require a different timing.
- the invention is thus characterized by the use of these types of program control units provided with two selector controls, with the difference that the second selector control, rather than being employed for selecting the functions of the drying cycle, is used in the laundering mode, specifically for the purpose of varying in a discrete manner, i.e. in determined steps, the rotary speed of the cam disc stack for certain phases of the cycle, and thus the duration of the respective phases.
- the disc 1 of the main selector control 2 of the program control unit and the disc 3 of the auxiliary selector control 4 operable to vary the duration of the various phases of the selected program.
- the selector controls each comprise a rotatable shaft acting on a respective gear 5, 6, the two gears being interconnected by a third gear 7 meshing with both of them.
- the temperature of 90° may be assigned to a so-called “regular” cycle, to a "long” cycle, or to a “short” cycle.
- the temperature T 2 may assume different values, for instance the value of 60° or 90°, depending on the position to which the auxiliary temperature selector control 4 has been brought, the temperture T in specie indicating the temperature of the liquid in the tub during the various phases.
- the complete laundering cycle is composed of four distinct phases designated by A, B, C and D on the time scale, the phase A representing the interval during which a detergent is mixed with cold water, B representing the phase during which the laundering bath is heated, C representing the laundering phase at substantially constant temperature, and the phase D representing a succession of rinsing steps.
- the individual phases are each composed of a number of time elements corresponding to the intervals during which the cam disc stack dwells at corresponding incremental positions.
- phase A comprises only one time increment 1
- phase B is composed of increments 2 to 7
- phase C is composed of increments 8 to 10.
- the rinsing phase D is not illustrated in detail, since it is not relevant in the context of the present invention.
- the invention provides that the various time increments are of variable duration, the attached Table A showing the complete succession of time increments for each cycle of a selected length, for each temperature, and for each phase.
- Table B shows the overall duration of the individual phases A, B and C as determined from Table A in accordance with the type (length) of the selected cycle.
- the corresponding time intervals for a cycle at a selected temperature of 60° may be similarly derived from Table A.
- Any laundry washing machine or dishwasher may of course be designed with circuitry outlays and arrangements different from what has been described without thereby going beyond the scope of protection of the present invention.
