Definitions
- the invention relates to a household machine, such as a dishwasher or a washing machine, according to the preamble of claim 1.
- two pumps have generally been used in dishwashers, one of the pumps being provided as a circulation pump during the washing operation and the other pump for pumping off the alkali after the end of a washing program or a program step. Both pumps are connected to the sump of the dishwasher on the suction side.
- the circulation pump supplies the spray arms of the dishwasher via the corresponding connection lines on the pressure side.
- circulation pumps are also known in washing machines, in order not only to wet the laundry with wash liquor via the drum movement, but also to spray it in order to reduce the water consumption.
- a synchronous motors are generally used for the liquid pumps, which are easy to implement in terms of structure and control.
- a disadvantage here is the poorer possibilities for speed control, which often results in a vibration and a related humming noise, which can ultimately be attributed to the ripple of the supply voltage.
- the object of the invention is to propose a household machine with a liquid circuit of the type mentioned in the introduction, in which the disadvantages mentioned above are reduced and which is also inexpensive to manufacture.
- a household machine is characterized in that at least one of the two pumps can be connected to a control unit for motor control and / or regulation.
- the invention takes advantage of the fact that the circulation pump and the drain pump or drain pump are generally not switched on simultaneously when such household machines are in operation. This makes it possible due to the time sequence in the operation of the two pumps, these with a common one Operate control unit for the motor control, which can be switched between the pumps via a corresponding switching element. With the help of the control unit according to the invention, the individual pumps can also be controlled much more flexibly.
- the pumps are connected in parallel, with a switchover of the control unit between the pumps being present in order to selectively enable the separate drive of each pump.
- At least one switching element in particular a relay or the like, arranged between the pumps is provided for motor control and / or regulation.
- at least one of the pumps can be switched off or on by means of the control unit.
- the control unit is advantageously designed to adapt the frequency increases per unit of time. This measure makes it possible that, especially when using synchronous motors as pump motors, the somewhat larger pump motor, for example, is not accelerated with a comparatively strong frequency increase per unit of time, ie with a so-called steep ramp, and thus does not perform a pumping function. In contrast, in this case the smaller one dimensioned pump motor follow the strong frequency increases per unit of time, so that it is accelerated and fulfills its pumping function. This means that in the case of a relatively steep ramp generated by the control unit, only the comparatively smaller pump motor rotates.
- both pump motors connected in series or in parallel can advantageously be accelerated and fulfill their pumping function.
- the pump motor which is smaller in comparison, can preferably be switched off by means of the advantageous switching element or relay, so that only the pump motor, which is larger in comparison, operates and fulfills its pumping function.
- the two pumps are driven by electronically commutated synchronous motors, with only one motor control coordinated with them having to be provided.
- the better speed control should be mentioned as an advantage, which on the one hand reduces the noise of the machine and on the other hand the energy consumption by more precisely adapting to the required power.
- a switchable motor control unit according to the invention is preferably implemented with the aid of a processor-controlled control unit. This only requires a processor and a driver stage, which can be single or multi-phase. Switching from one pump to another can be carried out under software control using a simple switching element, such as a relay or semiconductor switching elements.
- a DC voltage of 42 volts or less can be used in order to achieve the advantages mentioned above.
- control unit for the motor control other electrical or electronic components for additional functions can be integrated.
- a switching element for controlling and / or regulating a heater of the household machine via the control unit for the motor control.
- a regulation of the heating current and / or the time intervals of the switch-on come into question.
- the switching element itself is integrated into the control unit. This is particularly advantageous if the heating system for the liquid circuit is integrated in a liquid pump, since in this case the line routing for the heating runs parallel to the line routing for the pump drive.
- a switching element for current limitation is also provided.
- This switching element can in turn be operated via the control unit for the pump motors.
- the current limitation can cause an overload of the corresponding components, for example the pump motors or the liquid heating.
- one or more liquid circuits can additionally be switched over to the control unit for the pump motors.
- a switchover between the different spray arms is possible in that a corresponding liquid switch, switching valves or, generally speaking, a corresponding actuator is actuated via the control unit.
- one or more sensors are also used to control the operating states of the household machine and / or to protect against damage Overload or defects provided.
- Such a sensor can be designed, for example, as a pressure sensor that measures the liquid pressure in a liquid line.
- a load sensor that detects the current consumption of the pump motors is also conceivable as a sensor in such an application.
- Other sensors e.g. to measure temperature or liquid status, e.g. Foaming or contamination or clouding of the liquid can also be provided.
- the household machine according to the invention is developed so that the ripple of the rectified mains voltage is suppressed or at least significantly reduced in the control unit.
- software algorithms can be provided for the control processor, which are the rectified ones Adjust the supply voltage in such a way that the desired effect, eg the suppression of 100 Hz humming noises on the rotor of the pump motors, is achieved.
- Such a humming sound is often a problem after rectification of an alternating voltage customary in the network.
- a start-up algorithm is also provided in the control unit for the pump motors, which ensures the safe starting of the rotor.
- starting especially in the desired direction of rotation, can be a problem.
- a suitable start-up algorithm for example by alternating forward and backward rotation, the rotor can be rocked to a certain extent in resonance, thus ensuring that the motor starts reliably.
- an interface for data transmission to a suitable communication device is preferably formed in the control unit for the pump motors.
- electronic systems for home management or online diagnostics and maintenance will play an increasingly important role. Therefore, it makes sense if appropriate household machines are provided with the relevant interfaces.
- a so-called bus interface can be used to connect to a modern data bus.
- the power line network for the energy supply of the household machine is used as the medium for the data transmission.
- the desired information can be transmitted via the line network of the mains voltage.
- a wireless data transmission for example by means of radio or infrared or ultrasound transmission and reception units.
- the so-called “blue tooth” modules are particularly suitable for such data transmission.
- FIG. 1 shows a schematic block diagram to illustrate the electrical and electronic components of a household machine according to the invention
- Figure 2 another, schematic
- Figure 3 a third, schematic
- Block diagram for illustrating the electrical and electronic components of a household machine according to the invention.
- FIG. 1 shows a control unit 1 for controlling and / or regulating a household machine according to the invention.
- a central component of the control unit 1 is a computer 2 with a processor 3.
- Computer 2 has all the necessary components, not shown, such as data or program memory, a bus system, digital and / or analog Inputs and / or outputs, etc.
- a driver stage 4 which can be single-phase or multi-phase, can be controlled, which is provided for driving two pumps 5, 6.
- a pump 5 is provided as a circulation pump, while the other pump 6 serves as a drain pump of a dishwasher.
- the control unit 1 is switched between the two pumps 5, 6 with the aid of a switching element 7, which in the simplest case is designed as a relay.
- the switching element 7 is also actuated by the control unit 1 or the computer 2.
- control unit 1 is also capable of performing a large number of further functions.
- a plurality of sensors 8 are indicated on one side of the computer 2, which are intended to illustrate the detection of one or more machine parameters.
- One of these sensors 9 can be, for example, a load sensor for detecting the pump load or the pump current drawn, as indicated by the dashed line to the output line of the driver unit 4.
- a number of actuators 10 can also be actuated by the control unit 1. Via such actuators it is possible, for example, to actuate valves, as is illustrated with the aid of the actuator 11 and the schematically illustrated valve 12 , Such a valve can be used, for example, to trigger a spray arm switchover in a dishwasher or also a regeneration process for an ion exchanger.
- Such an actuator can, as with the actuator 13 indicated, a metering device 14, for example, for detergents or rinse aids can be actuated. In principle, all necessary machine functions can be performed by the control unit 1 via such actuators.
- a wireless interface 15 is indicated, which can be a "blue tooth” module, for example.
- the interface 15 is used for communication with an external computer, for example for household management or for external online monitoring and possibly - maintenance of the household machine.
- control unit 1 can display information to an operator and can receive information from the operator.
- FIG. 2 shows a variant according to the invention, wherein the control unit 1 can also include the peripheral components according to FIG. 1 without a more detailed illustration.
- the household machine according to FIG. 2 has two pumps 5, 6 connected in series.
- the switching element 7 or relay 7 is arranged between these.
- the smaller pump 6 is generally switched off with the relay 7 in the case in which only the larger pump 5 is to be operated.
- the control unit 1 switches on the pump 5 with a comparatively flat ramp, ie with a relatively small increase in frequency per unit of time, so that the pump 5 is accelerated.
- the slope of the switch-on ramp essentially depends on the dimensioning or the acceleration properties of the pump 5.
- the control unit drives both pumps 5, 6 with a comparatively steep switch-on ramp, ie with a relatively large increase in frequency per unit of time or high acceleration.
- the ramp must be chosen so steep that the larger pump 5 is not accelerated due to its dimensions or acceleration properties or does not start to rotate.
- At least four different operating states of the pumps 5, 6 can be implemented in an elegant manner by means of a control unit 1, which can change or adapt the switch-on ramps, and a switching element 7:
- control unit 1 can be used as a central control and regulating unit of the corresponding household machine. What is essential in the invention is the function as a control unit for two pumps 5, 6, i.e. in the exemplary embodiment shown for the circulation pump 5 and the drain pump 6. As a result, motors can be used for the pumps 5, 6, which require more complex control than conventional machines, the resulting costs being offset by the fact that only one control electronics or only one control computer 2 and only one driver unit 4 is provided for both pumps 5, 6.
- FIG. 3 shows a further variant of the invention, the pump 5 and the pump 6 or their coils being supplied with electrical energy by means of two phases P1 and P2 and a star point S.
- FIG. 1 or 2 further components or details (cf. FIG. 1 or 2) are not shown in detail, but these are accordingly provided in a household machine according to the invention.
- a series connection of the two pumps 5, 6 is realized.
- the individual pumps 5, 6 are controlled with a relatively steep or flat ramp, comparable to the exemplary embodiment according to FIG. 2.
- pump 5 is a smaller pump and pump 6 is a larger pump.
- the larger pump 5 is not accelerated or stops and does not pump with a relatively steep switch-on ramp.
- the smaller pump 6 is accelerated and pumps the corresponding medium according to its function.
- both pumps 5, 6 are accelerated in the position shown and pump the respective medium according to their functions. If, in contrast, the relay 7 is closed, the pump 6 is put out of operation or decoupled and only the larger pump 5 can be operated or controlled.
- a correspondingly flat switch-on ramp (cf. above) is generally selected so that the pump 5 advantageously accelerates and can be operated without losses in an almost optimal state.
