Abstract

Disclosed is an electrical household appliance comprising a chamber that is at least partially filled with liquid during operation of the appliance, a motor (9)-driven pump (5) for sucking liquid from said chamber, and a monitoring device (31) for detecting the rotational speed and the power of the motor (9), comparing detected values for the rotational speed and power to a predefined characteristic, and signaling an exceptional state if the comparison indicates that the detected values deviate significantly from the characteristic.

Description

  • The present invention relates to a household electrical appliance having a chamber at least partially filled with liquid during operation of the apparatus and a pump driven by a motor for drawing liquid from the chamber. In particular, such a household appliance may be a dishwasher or washing machine, and the pump is a drain pump which draws cleaning liquor from a lower part of the chamber to spray it on to be cleaned in the chamber, or to pump it out of the chamber , Such a dishwasher is eg from JP 06 014862 A known.
  • If the amount of wash liquor in the chamber is too low, unsatisfactory cleaning results are achieved because the pump sucks in addition to the cleaning liquor and air sufficient for sufficient cleaning results Laaugruck the pressure outlet of the pump is not achieved. If, however, the amount of time in the chamber is greater than necessary, this leads to an uneconomical operation on the one hand because of unnecessarily high water costs, on the other hand, because together with the amount of alkali and the energy required to heat the liquor increases to a desired cleaning temperature. It is therefore important to adjust the amount of alkali exactly to the needs. This can for example be done by a flow meter is installed in an inlet line of the chamber, which monitors the amount of fresh water introduced and causes the blocking of a valve in the inlet line when a designated amount of water is reached. Such a flowmeter is not only costly, it is also not able to adjust the amount of water taken in each case to the degree of contamination of the machine to be cleaned with the goods. For example, if a dishwasher is loaded with heavily soiled dishes, so contained in the dirt proteins lead to a strong foam formation of the rinse liquor, with the result that not only rinsing liquor, but also foam is sucked by the pump. Just as with air drawn in too low a level of leach, the foam prevents the build-up of a sufficiently high pressure at the pump outlet and thus a satisfactory cleaning effect. Foaming may be counteracted by ingesting a larger amount of water, but this, when done during each cleaning operation, is uneconomical, as stated above. Conventional dishwashers therefore often have program buttons, the allow a user, depending on the degree of contamination of the invited dishes to select different washing programs with different water use. Since the assessment of the degree of contamination by the user to some extent is subjective and the use of the appropriate selection key is also easily forgotten, optimal profitability can not be guaranteed.
  • With a machine that is able to adjust the amount of water used in each case individually to the degree of contamination of the goods to be cleaned, not only an increase in comfort for the user, but also to achieve an improvement in efficiency.
  • If the cleaning solution is heavily soiled, it may cause blockage of the pump or its upstream or downstream lines blocking the movement of the pump and thus of the motor. Since in such a case, the engine does not perform any mechanical work, the entire - under such circumstances may even increased compared to the normal operation - absorbed by him electrical power is converted into heat, which may cause damage or even destruction of the engine. Although in principle it is possible to detect such a blockage by means of a flow meter connected in series with the pump of the type mentioned above, such a sensor is, as stated, expensive and blocks valuable space in the household appliance.
  • The object of the invention is to provide an electrical household appliance of the type defined, which allows the detection of disturbances of the liquid flow through the pump with simple, inexpensive and reliable means.
  • The object is achieved by an electrical household appliance having the features of claim 1.
  • The invention assumes that there is a fixed relationship between the speed and power of the engine, which is essentially determined by the design of the pump and the flow resistance of lines through which the pump pumps the fluid. Deviations from these up, or down, empirical ascertainable relationships for a given model of home appliance all indicate different types of disturbances. Therefore, the home appliance includes a monitor for detecting the speed and power of the motor, comparing detected values of speed and power with a predetermined characteristic, and for signaling a state of exception when the comparison reveals that the detected values deviate significantly from the characteristic.
  • If the engine power detected at a detected engine speed is significantly less than what is expected for the detected engine speed from the given characteristic, this is an indication that not only liquid but also foam or air is being pumped. Both problems can be remedied by adding additional water into the chamber of the household appliance. Therefore, the home appliance includes an inlet valve for introducing liquid into the chamber and a controller configured to open the inlet valve when the monitor signals a first exception in which the sensed speed is significantly less than one for that Speed based on the characteristic expected power value.
  • Similar to a sensed power that is less than expected for the sensed speed based on the characteristic, is the detection of a speed that is significantly higher for a given power than expected from the characteristic.
  • The household appliance may have a plurality of Umwälzwegen, over which the circulated by the pump liquid is selectively feasible, as described in Wegner, Household Appliances / Technology and Service, Publisher Hüthig & Pflaum, 2000, for a dishwasher. Since such different Umwälzwege usually have different flow resistance, the monitoring device is advantageously set up, depending on the selected Umwälzweg a specific for each selected Umwälzweg characteristic comparison.
  • It may also be expedient to base the comparison in the course of the operation of the household appliance changing characteristics. Thus, e.g. in an initial phase of the operation of a dishwasher, a first characteristic based on the assumption that at this time a deviation from the characteristic indicates that the pump sucks in air due to insufficient amount of liquor. In a later phase of the procedure, in particular if an adjustment of the amount of liquor has already taken place based on the above-mentioned first characteristic, a different characteristic of power and rotational speed can be used to detect the foaming.
  • If the monitoring device signals a second exception state in which the power detected together with a detected instantaneous rotational speed is significantly higher than expected on the basis of the given characteristic, then this is indicative of a malfunction in the movement of the engine. In this case, it may be provided that the control device stops the operation of the household appliance to protect the engine, or that it outputs a warning signal to prompt a user to take countermeasures to protect the engine.
  • It is known per se to precede the inlet of the pump with a filter for trapping impurities in the pumping liquid. An excessive power of the motor in relation to the rotational speed can also indicate a blockage of this filter, so that a suitable reaction of the control device to an excessive power detected by the monitoring device can also be to control a cleaning, in particular a purging of this filter or to induce.
  • Preferably, a synchronous motor is used as the engine in the household appliance according to the invention. Such a motor allows comparatively simple detection of its speed solely by monitoring the time course of the electromotive force in the windings of the motor, i. the currents or voltages occurring at the motor, so that costly and space-consuming sensors on the engine or the pump to determine the speed are not required.
  • Preferably, the rotor of the motor is arranged in a pump chamber of the pump. Such a runner, also referred to as a wet runner, makes it possible to dispense with a seal on the shaft between the rotor and the pump, at which friction losses in strength which can not be precisely controlled could occur. This design of the rotor therefore allows a particularly accurate inference of the electrical power absorbed by the engine to the mechanical power delivered by the pump.
  • Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures.
  • Show it:
  • Fig. 1 a schematic section through a dishwasher according to the invention;
  • Fig. 2 a block diagram of the motor of the circulation pump of the dishwasher Fig. 1 as well as its supply electronics;
  • Fig. 3 Examples of the engine governing speed-power characteristics; and
  • Fig. 4 a section through an assembly in which the pump, the engine and the Supply electronics are summarized.
  • Fig. 1 shows a schematic section through a dishwasher with a rinsing chamber 1, in the usual way baskets 2, 3 are guided out on rails pulled out arranged. In a recess at the bottom of the rinsing chamber 1 is a rinsing water filter 4 through the one later with respect to Fig. 2 More specifically, pump 5 sucks rinse water to feed rotatably mounted nozzle arms 6, 7, which are each mounted below the baskets 2, 3, to spray the items contained therein. A directional control valve 8, which is mounted between the outlet of the pump 5 and the nozzle arm 6 or 7, is controlled by a microcontroller 31 (see FIG. Fig. 2 ) between the position shown in the figure, in which the lower nozzle arm 7 is supplied via a line 13 with rinse water, and a position switchable periodically, in which the upper nozzle arm 6 is supplied via a line 12.
  • Of course, in a simpler embodiment, the valve 8 could also be omitted, so that both nozzle arms 6, 7 are supplied simultaneously. In this case, however, during operation of the nozzle arms 6, 7, both lines 12, 13 must be filled with water at the same time, so that the total amount of water required for rinsing is greater than during alternating operation of the spray arms 6, 7 with the aid of the valve 8.
  • An inlet valve 10, which is likewise controlled by the microcontroller 31, serves for the controlled admission of fresh water into the rinsing chamber via a fresh water line 11.
  • The pump 5 is driven by a brushless DC motor 9, which is powered by a supply electronics block 20 with electrical energy. The motor 9 and the supply electronics block 20 are in Fig. 2 shown in more detail in a block diagram. The motor 9 has three stator windings, designated U, V, W, which are interconnected here in a stem configuration. The supply electronics block 20 comprises a mains rectifier 21, which supplies an intermediate DC voltage. This intermediate DC voltage feeds three phases of an inverter 22, each comprising two series-connected switches SU1, SU2 and SV1, SV2 and SW1, SW2, each in the form of a power transistor with a parallel freewheeling diode. The point between two switches of each phase is connected to the associated winding U, V or W of the motor. The state, open or closed, of each switch is controlled by a switching pattern generator 23, which receives a signal representative of the instantaneous phase δ of the motor shaft from a phase detector 24 and, based on this phase signal, the energization of the stator windings U, V, W of the motor 9 so determines that the magnetic field generated by the stator windings U, V, W in the motor 9 has a certain projection before the phase of the rotor and this drives.
  • The phase detector 24 may be formed by one or more magnetic field sensors, such as Hall sensors, which are exposed to the magnetic field of the rotor or of magnets coupled to the rotor. Preferably, it is a purely electronic phase detector, such as in US-A-5859520 described, which evaluates a zero crossing of the induced in a temporarily de-energized winding U, V or W of the motor by the magnetic field of the rotor electromotive force to derive therefrom the phase ö of the rotor.
  • The phase signal supplied from the phase detector 24 is also received by a speed measuring circuit 25 which determines the rotational speed n of the motor 9 therefrom by taking a time derivative, measuring the period or the like.
  • The speed measuring circuit 25 supplies a signal representative of the detected speed n to a monitoring circuit 26.
  • A current measuring circuit 27 has two inputs, which are connected to the two terminals of a measuring resistor 28 which is connected in series with the inverter 22 between the output terminals of the mains rectifier 21. The current flowing through the measuring resistor 28 is therefore the sum of the currents flowing through the three phases of the inverter 22 and is thus - assuming a constant intermediate circuit voltage at the output of the rectifier 21 - proportional to the electrical power absorbed by the motor 9. Accordingly, the voltage difference between the two input terminals of the current measuring circuit 27 is proportional to the received electric power. The current measuring circuit 27 supplies a digital signal representative of this power to the monitoring circuit 26.
  • In a read-only memory 29 connected to the monitoring circuit 26, a plurality of speed-power characteristics are stored, each describing a relationship between speed n and absorbed electric power P corresponding to normal operation. These characteristics, which depend in particular on the shape and passage cross-section of the paths over which the rinse water is pumped, have been determined in advance on a prototype of the dishwasher. Fig. 3 shows two such characteristics, denoted by C1 and C2, where C2 corresponds to a higher flow resistance than C1, as occurs approximately in the operation of the upper spray arm 6, because the head to be overcome is greater than in the case of the lower spray arm 7. The monitoring circuit 26 selects each one of the current position of the directional control valve 8 associated characteristic, for. B. at the in Fig. 1 shown position of the directional control valve 8, the characteristic C1, reads the according to this characteristic C1 corresponding to a current speed supplied by the speed measurement circuit 25 theoretical power value from the read-only memory 29 and compares this with a calculated using a simultaneously supplied by the current measuring circuit current value 27 current performance. If the current power value deviates by more than an allowable amount from the theoretical power value, the monitoring circuit 26 generates a fault message, which is output to a programmer 30 and which specifies the direction of the deviation.
  • If the measured power is significantly lower than the theoretical, ie if the value pair of current speed and power in the increasingly hatched area of the graph Fig. 3 is located, it means that the pump 5 sucks not only water, but also foam or air. If this condition is detected at the first start of the pump 5 after the introduction of water at the beginning of a rinse, this is due to the fact that the amount of water in the rinsing chamber 1 is not evasive. The programmer 30 then opens the inlet valve 10 to admit fresh water into the wash chamber 1 until the monitor circuit 26 stops reporting the disturbance or until a predetermined amount of time has elapsed. If, after the lapse of this time, the trouble message has not yet disappeared, the programmer 30 locks the inlet valve 10 and stops the flushing operation to preclude the flushing chamber 1 from being overfilled with water due to a detection error. At the same time, the programmer 30 activates an indicator light (not shown) on the housing of the dishwasher to alert a user of the failure.
  • If a too low in relation to the speed of the engine performance at a later time of the washing program, after the dosing of detergent, is detected, the disturbance is usually not due to a priori too low water level, but on a strong foaming, which causes foam to be sucked into the pump. To reduce the foam, the programmer 30 also opens the inlet valve 10, but only for a predetermined short time. Thereafter, the purging operation may continue, with the programmer 30 then ignoring the fault message for a predetermined period of time to allow the foam in operation to dissipate, or the operation of the machine is interrupted for a few minutes to allow the foam to dissolve.
  • If the fault signal of the monitoring circuit 26 indicates that the power of the motor 9 for the measured speed is too high, then in most cases a clogging of the filter 4 is the cause. In this case, the programmer 30 aborts the flushing process and indicates by means of a signal light on the device housing on the unscheduled termination of the wash program. If the filter 4 is of the self-cleaning type, pumping out the rinse water after the program termination may already be sufficient to clean the filter 4, so that a user only needs to restart the machine. Otherwise, it must clean the filter 4 itself before restarting the machine.
  • In principle, it is possible to implement all the above-mentioned components 23 to 30, possibly with the exception of the measuring resistor 28, in a common microcontroller. In the presentation of the Fig. 2 a symbolized as a dashed frame microcontroller 31, the components 23 to 27 and 29; the programmer 30, which controls not only the pump 5 but also components removed therefrom, such as the directional control valve 8, heaters (not shown), intake and exhaust valves, and processes user's commands, is spatially separated from the microcontroller 31.
  • A preferred embodiment of an assembly, in which the microcontroller 31, the motor 9 and the pump 5 are combined, is in Fig. 4 shown in section.
  • The pump 5 is a vane pump with a housing of a front housing shell 41 and a pot-shaped plate 42 which define a one-piece pump chamber. In the pump chamber, an impeller 43 and, engaging in the cup-shaped indentation of the shield 42, a rotor 44 of the brushless DC motor 9 accommodated. The rotor 44 is immersed in and cooled by the liquid pumped by the pump. The stator 45 of the motor 9 is mounted on a housing shell 46, in which a circuit board 47 is anchored, which carries the microcontroller 31 and the measuring resistor 28. The assembly of housing shell 46 and stand 45 is slipped outside over the plate 42 in the manner of a cup.
