Definitions

  • the invention relates to a method as claimed in the preamble of claim 1 .
  • the energy consumption required for the various operations and the time required for these are important performance parameters, which are not independent but closely linked, to some extent even conversely in that one is minimized at the cost of the other.
  • the washed dishes are generally dried in the washing compartment in a drying operation. Various methods and principles are known for this.
  • a heating facility supplies heat to the interior space of the washing compartment but the moisture is not conducted away.
  • the temperature of the interior air of the washing compartment rises in this process, with the result that it can take on an increased relative air humidity.
  • a cold surface enhances the drying performance.
  • the moisture from the interior air can condense on it, thereby maintaining or increasing the capacity of the interior air to absorb moisture.
  • the object of the present invention is to optimize the drying operation in a dishwasher. It should be possible to achieve optimized drying economically and in a technically simple manner; in particular it should be possible without technically complex sensors and/or without apparatus that is required specifically for drying.
  • the invention is based on a method for regulating a drying period in a dishwasher having a washing compartment for receiving items to be washed, the items to be washed being heated to a predetermined initial temperature (T 0 ), which is above the temperature of a condensation surface communicating with the washing compartment.
  • the feature characteristic of achieving the complete drying of the items to be washed can be the reaching of or being above or below an appropriately selected critical value that is characteristic of complete drying, i.e. a threshold of the characteristic temperature (T).
  • Identification of the characteristic feature can include identification of the reaching of an end temperature or the start of an asymptotic behavior of the time dependency of the characteristic temperature. It is thus possible to identify that complete drying has been achieved and to terminate the drying operation prematurely, i.e. for example before the end of a programmed drying period, thereby saving time.
  • the temporal derivation of the temperature signals can be calculated and supplied for evaluation by software processed in a processor of a central control unit.
  • the detection of such characteristic features of the characteristic temperature allows automatic drying identification.
  • automatic drying identification By selecting the characteristic temperature and the characteristic features appropriately it is possible for automatic drying identification to be independent or largely independent of the (heat and noise) insulation of the washing compartment, ambient conditions such as the ambient temperature (e.g. in summer and winter) and the specific installation situation of the automatic dishwasher (e.g. freestanding or built into a kitchen unit between adjacent cabinets on the right and left).
  • the method has the advantage that the drying operation can be controlled as a function of load. With a small load it is therefore possible to save energy and with a larger load an adequate drying result can still be achieved. Optimization is generally a matter of terminating the drying operation when the drying result is adequate.
  • a temperature sensor with associated signal evaluation is required according to the invention.
  • Naturally two or more temperatures disposed in different positions can also be used, their temperature signals being linked to obtain the characteristic temperature, for example by forming a temperature difference.
  • the dishwasher has means for detecting the load or the load quantity.
  • the initial temperature for a drying operation with inherent heat is determined before the start of the drying operation as a function of the detected load.
  • a suitable initial temperature and/or a quantity of thermal energy to be supplied to heat the items to be washed can also be predetermined as a function of the load before the items to be washed are heated.
  • the load here can be expressed for example by the quantity, thermal capacity and/or total surface of the items to be washed.
  • the drying operation can thus be optimized as a function of the load, for example being shortened in the case of a smaller load.
  • the characteristic temperature can essentially be detected at different places in the dishwasher. It can be a temperature characteristic of the condensation surface for example. The characteristic temperature can also be a temperature that is characteristic of the temperature of the items to be washed.
  • a differential temperature can be formed for example from the temperature characteristic of the temperature of the items to be washed and the temperature characteristic of the temperature of the condensation surface.
  • the temperature of a thermal reservoir can optionally also serve as the temperature of the condensation surface. Evaluating the differential temperature reduces or eliminates the influence of the ambient temperature and/or the installation situation and/or the influence of the heat and sound insulation around the washing compartment, thereby allowing the characteristic feature to be identified even more reliably.
  • a dishwasher is also proposed that has a washing compartment for items to be washed and a condensation surface communicating with the washing compartment and also means for heating the items to be washed in the washing compartment.
  • the dishwasher also has means for detecting a time dependency (T(t)) of a characteristic temperature (T) and means for detecting a feature of the time dependency of the characteristic temperature that is characteristic of the degree of evaporation of water from the surface of the items to be washed.
  • T(t) time dependency of a characteristic temperature
  • T characteristic temperature
  • the loading door can serve as the condensation surface for example. Since in the case of conventional dishwashers the loading door already holds electronic components and elements of the sequence controller, a temperature sensor can be built in there economically with little additional technical outlay.
  • the condensation surface preferably communicates in a thermally conducting manner with an element of high thermal capacity, for example with a water or thermal reservoir regulated to a relatively low temperature.
  • the condensation surface can then be a surface of the thermal reservoir communicating with the washing compartment.
  • the temperature of the condensation surface only changes insignificantly as the items to be washed are heated, bringing about an effective condensation and therefore also drying effect.
  • the influence of the ambient temperature (e.g. summer, winter) or the installation situation (e.g. proximity to other heat-generating appliances) on the characteristic temperature is at least reduced due to the high thermal capacity of the water or thermal reservoir.
  • the detection means can be configured to detect the time dependency of a temperature characteristic of the temperature of the condensation surface and can for example be a temperature sensor coupled thermally to the condensation surface.
  • the detection means can be configured to detect the time dependency of a temperature characteristic of the temperature of the items to be washed and can for example be a temperature sensor coupled thermally to water circulated through the washing compartment.
  • An appropriate location for this can be the pump sump of the automatic machine for example.
  • the detection means can comprise one or more of the following means: (i) means for identifying that an end value is reached, (ii) means for identifying the start of an asymptotic behavior as the end value of the characteristic temperature is approached, (iii) means for identifying that a threshold of time dependency is reached and/or (iv) means for identifying a threshold of the derivation according to time or the temporal derivation of the time dependency of the characteristic temperature.
  • These means can be implemented in the form of software modules, which evaluate temperature measurement signals of the detection means.
  • a central controller can also be provided with a processor that can be programmed using software.
  • the dishwasher can also have means for supplying the first derivation according to time of the time dependency of the characteristic temperature and the detection means can have means for identifying that an end value is reached or the start of an asymptotic behavior as the end value of the temporal derivation of the characteristic temperature is approached. Alternatively it can have means for identifying that a threshold of time dependency or a threshold of the temporal derivation of the time dependency of the characteristic temperature has been reached. These means can also be provided in the form of software modules executed in the processor.
  • a first temperature sensor can be disposed in a circulation circuit of the water circulated through the washing compartment, for example in a circulation pump.
  • the temperature measurement can be carried out on a medium that exchanges heat with the items to be washed, for example the basket holding the items to be washed, or in the washing compartment, e.g. in proximity to the receiving site for the items to be washed.
  • a second temperature sensor in thermal contact with the condensation surface or the surface of the temperature reservoir.
  • one embodiment of such a detection and calculation facility can have a first temperature sensor in the reservoir.
  • a second sensor can be disposed in the washing compartment and a third in the detergent dispenser in the loading door.
  • the calculation facility in each instance forms a ratio value (quotient) from simultaneously detected values of the second and third sensors and subtracts this from a simultaneously measured temperature value of the first sensor.
  • a curve with a falling gradient which approximates asymptotically to a temperature as a threshold, results for a number of time points detected within a time interval. The threshold symbolizes complete drying. If the curve has approximated to this up to a certain approximation sum or even reaches the threshold, the control unit receives a corresponding signal, whereupon it terminates the drying operation.

  • FIG. 3 shows a schematic cross section (side view) of a dishwasher
  • FIG. 4 shows a schematic cross section (front view) of a dishwasher with a temperature reservoir.
  • FIG. 1 shows operations in a dishwasher with inherent heat drying according to the prior art. They comprise a prewash operation 2 , a first cleaning operation 4 , a second cleaning operation 6 , an intermediate rinse operation 8 , a final rinse operation 10 and a drying operation 12 that completes the operations.
  • prewash operation 2 cold fresh water (approx. 3.4-3.9 l) is fed in and circulated through the washing compartment 14 (see FIGS. 3 and 4 ) for a preset period of approx. 15 mins by means of a circulation pump 20 disposed below the washing compartment 14 .
  • detergent is introduced into the washing compartment 14 and the fresh water fed in for the prewash is heated to an initial cleaning temperature of approx. 51° C. for a period of approx.
  • a heating apparatus (not shown) disposed in the hydraulic circuit heats the circulated water to the temperature desired in each instance in an operation.
  • the heated water now provided with detergent, is circulated.
  • the cleaning operation 6 represents the main cleaning operation for the dishes 28 disposed in the washing compartment 14 .
  • the washing water is pumped out of the washing compartment 14 and clean fresh water is fed in.
  • the fresh water is circulated for a period of approx. 5 mins during the intermediate rinse operation 8 and is heated in the process by contact with the elements in the washing compartment 14 that are still warm from the cleaning operation 6 , for example the items to be washed 28 , 28 a , 28 b , a basket 30 , a water spray rotating arm 24 and the walls of the washing compartment 14 as well as elements in a circulation circuit 22 a , 20 , 22 b .
  • the intermediate rinse water is pumped out of the washing compartment 14 and cold fresh water is fed in again.
  • the cold fresh water fed in is circulated for a predetermined fixed time, e.g. approx. 15 mins, in the final rinse operation 10 and in this process heated with a predetermined fixed heat output to the initial temperature T 0 for the final drying operation 12 , e.g. to approx. 65° C.
  • FIG. 2 shows the gradient of temperature over time or the time dependency of the temperature in the washing compartment for different loads during the final rinse operation 10 and the drying operation 12 .
  • the temperature shown in FIG. 2 can be the abovementioned characteristic temperature here. It can also be a temperature T 1 of the circulated water measured for the temperature of a part 28 a or 28 b of the load or measured by means of a first temperature sensor 32 .
  • FIG. 2 shows the gradient over time T n (t) for a load n defined as standard and comprising a specified quantity of dishes and cutlery as well as the gradient over time T n ⁇ (t) for a smaller load n ⁇ than the standard load and the gradient over time T n+ (t) for a larger load n+ than an accepted standard load.
  • the heat output supplied raises the temperature in the washing compartment 14 and therefore also the temperature of the items to be washed 28 a , 28 b during the final rinse operation 10 essentially in proportional to the time t.
  • the temperature rise shown in FIG. 2 which is less than proportional, is due to heat transfer loss, for example through the walls of the washing compartment 14 and through the loading door 16 to elements of the appliance outside the washing compartment 14 .
  • the temperature rises during the final rinse operation 10 according to the middle curve T n (t) up to a temperature T 0 , the initial temperature for the temporally subsequent drying operation 12 .
  • the drying operation 12 starts when the heat output is deactivated.
  • the temperature T n (t) changes its gradient essentially according to a falling exponential function.
  • the load dries increasingly, in other words a film of moisture on the items to be washed 28 a , 28 b evaporates and condenses on a cold surface, e.g. a cold wall or the inside of the loading door 16 in the washing compartment 14 .
  • the gradient of temperature over time T n (t) reaches a temperature T 12,n , which then only changes insignificantly and marks the reaching of an asymptotic state.
  • the film of moisture on the items to be washed 28 is then completely evaporated.
  • the drying operation 12 for the load n can be terminated at time t 12,n .
  • the temperature gradient T n (t) corresponds to the characteristic feature to be detected for the degree of evaporation.
  • the reaching of the asymptotic state is the characteristic feature of complete drying of the items to be washed 28 .
  • By detecting the gradient T(t) of the characteristic temperature T over time it is possible to identify the end of the drying operation 12 and terminate the drying operation 12 . It is possible for example to generate a visual or acoustic signal for “Drying terminated” or even a control signal internal to the appliance, whereupon the drying operation 12 is terminated and the automatic dishwasher is turned off and/or switched to a ready state for opening the loading door 16 and emptying the washing compartment 14 .
  • the temperature T n+ (t) for the larger load n+ drops less steeply at the start of the drying operation than for the standard load n and the asymptotic state is reached later at the temperature T 12,n+ at time t 12,n+ .
  • the complete drying of the items to be washed 28 as a function of the load is identified by detecting the reaching of the asymptotic state of the temperature gradient. This can be used to terminate the drying operation 12 when complete drying has been achieved and thus always to achieve an adequate drying result (complete drying) as a function of the load.
  • the drying operation is therefore optimized compared with a drying operation with permanently programmed sequence parameters (fixed initial temperature, fixed drying time), as the drying operation 12 can be terminated earlier for a smaller load than it can with conventional automatic dishwashers with a permanently set drying period.
  • the characteristic temperature is a temperature in the washing compartment 14 , e.g. the temperature of the items to be washed 28 a , 28 b .
  • the characteristic temperature can however also be another measured temperature variable, as in the embodiments of the invention illustrated in FIGS. 3 and 4 .
  • a dishwasher according to FIG. 3 comprises a washing compartment 14 , in which the items to be washed 28 , specifically plates and cups, are placed in a basket 30 , a loading door 16 hinged to the washing compartment 14 , which is closed during the operations shown in FIG.
  • a water spray rotating arm 24 with a number of spray nozzles 26 which is disposed in a rotatable manner in the washing compartment 14
  • a circulation pump 20 disposed below a base wall 19 of the washing compartment 14
  • an inlet 22 a of the circulation line which connects a pressure output side of the circulation pump 20 to the water spray rotating arm 24
  • an outlet 22 b of the circulation line which is connected to an intake side of the circulation pump 20
  • a first temperature sensor 32 and a second temperature sensor 34 each connected by way of electrical or optical lines to corresponding temperature readout apparatuses for evaluating the temperature measurement signals generated by the temperature sensors 34 , 36 .
  • the first temperature sensor 32 is disposed in the circulation pump 20 . It serves to measure a temperature T 1 or to detect the time dependency T 1 ( t ) of the washing liquor in the circulation circuit. It can however also be disposed at different positions in the circulation circuit, for example in the inlet 22 a , outlet 22 b or in a depression in the base wall of the washing compartment 14 in proximity to the opening of the outlet 22 b.
  • the second temperature sensor 34 is disposed in contact with the inner wall, i.e. the wall of the loading door 16 facing the washing compartment 14 . It serves to measure a reference temperature T 2 or to detect the time dependency of the reference temperature T 2 ( t ), which is characteristic of the temperature of a cold surface in the washing compartment 14 . It can however also be disposed in different positions, for example in a control panel 18 in the loading temperature 16 , where it can easily be connected to the associated temperature readout apparatus by means of electric cables that are present there anyway.
  • the temperature T 1 of the water measured by the first temperature sensor 32 in the circulation circuit will drop after the heat output is deactivated at the end of the final rinse operation from the start of the drying operation.
  • the gradient over time T 1 ( t ) can be illustrated by a curve that drops over the course of time with a form similar to the form shown in FIG. 2 .
  • the temperature T 2 measured by the second temperature sensor 34 at the condensation surface rises during the final rinse operation due to heat transfer into and through the walls of the washing compartment, but more slowly than the temperature T 1 .
  • the feature characteristic of the achievement of complete drying of the items to be washed is the falling below an approximately selected critical value characteristic of complete drying, i.e. a threshold for ⁇ T 12 .
  • the dishwasher in FIG. 4 also has a thermal reservoir 38 as a temperature reservoir, which is located on a side wall of the washing compartment 14 .
  • the thermal reservoir 38 is configured in the form of a vessel disposed parallel to the side wall of the washing compartment 14 .
