Definitions

  • the invention relates to a cleaning device, in particular a household vacuum cleaner, with a blower and a pressure sensor for determining a negative pressure generated by the blower, the pressure sensor being an absolute pressure sensor.
  • the invention relates to a method for operating such a cleaning device.
  • Cleaning devices of the aforementioned type are known in the prior art. These can also have a device for varying the blower output of the blower in order to free the area to be cleaned of suction as best as possible. It is also known here to vary the blower output as a function of a flow resistance of an attachment of the cleaning device, so that the best possible cleaning result requires the least possible pushing force for moving the cleaning device over the surface to be cleaned.
  • the pushing force to be used depends, among other things, on the floor covering, for example a hard floor or a carpet.
  • differential pressure sensors are used to measure the negative pressure generated by the blower.
  • the disadvantage here is that the absolute pressure, which also contributes to the flow resistance of the attachment, is not taken into account. This adversely affects the cleaning result.
  • a cleaning device is known in which filter cleaning can be triggered as a function of a measured differential pressure.
  • absolute pressure sensors can also be provided with regard to the pressure sensors.
  • the invention is concerned with the task of specifying a cleaning device which enables the most advantageous determination of the pressure loss.
  • This object is achieved in terms of the device in the subject matter of claim 1, the focus being on the fact that an evaluation and control device is provided which is designed to provide a resulting suction power of the cleaning device as a function of a negative pressure determined by means of the pressure sensor, a current blower power and a current one To regulate the fan speed.
  • the negative pressure determined from the absolute pressures and the corresponding volume flow of the blower which can be found in the blower characteristic curve of the blower, determine the flow resistance of the attachment and thus also the pushing force to be used to move the attachment.
  • This flow resistance is used by the evaluation and control device in order to regulate the resulting suction power of the cleaning device so that on the one hand the flow resistance is as low as possible and on the other hand the best possible cleaning result is achieved.
  • the evaluation and control device can in particular be set up to control a constant suction power.
  • the volume flow through the blower depends (among other things) on the current blower output, which can be determined from the current and voltage decrease of the blower. Current and voltage of the blower are measured, for example appropriate devices measured on a circuit board of the blower. The speed of the fan is also measured in the usual way using a tachometer.
  • the evaluation and control device can thus determine the flow resistance on the basis of the aforementioned measurement data and known characteristics of the blower, which is used to control the suction power of the cleaning device.
  • the absolute pressure sensor advantageously has a detection area which is assigned to a suction area of the blower arranged in a connection area for a front attachment, ie. H. an area which is acted upon by the suction force of the fan.
  • This suction area is usually located in the cleaning device where an attachment is connected to the cleaning device.
  • the absolute pressure sensor measures the ambient pressure when the fan is switched off, on the one hand during a first measurement. H. without applying the suction air flow generated by the blower to the detection area, and on the other hand, during a second measurement, the absolute pressure when the blower is switched on.
  • the pressure difference calculated from these two absolute pressures is corrected from the current ambient pressure, so that the cleaning result is optimal regardless of the current ambient pressure.
  • the detection area of the absolute pressure sensor is assigned to the suction area in that the absolute pressure sensor is arranged directly in the suction area of the connection area.
  • the pressure sensor is in a blow-out area of the blower, in particular in a blow-out area printed circuit board of the blower, a measuring channel is formed between the pressure sensor and the detection area, the first end area of which is assigned to the pressure sensor and the second end area of which opens into the suction area.
  • the location of the detection area and the location of the pressure sensor are different. This makes it possible to cool the pressure sensor in the blow-out area of the fan by means of the blow-out air of the fan. The absolute pressure in the suction area is measured via the measuring channel.
  • the measuring channel has a first and a second end area, the first end area being brought up to the pressure sensor and in particular making contact with the printed circuit board in such a way that the pressure sensor projects into the measuring channel, and the second end area projecting into the suction area, in particular into a flow path of the suction air flow generated by the blower from the header to the blower.
  • the measuring channel be a hose section.
  • This tube section can be glued to the printed circuit board with its first end region or connected to the printed circuit board in some other way.
  • the open end face of the measuring channel is particularly advantageously covered by a partial area of the printed circuit board, so that the measuring channel is connected to the printed circuit board as fluid-tight as possible.
  • the hose section in particular in the form of a flexible hose section, is guided into the suction area, the second end area there also advantageously being fluid-tightly connected to a suction channel of the connection area.
  • a partial area of the housing of the cleaning device as a measuring channel.
  • the measuring channel can, for example, be molded into the housing of the cleaning device, advantageously in an injection molding process. At the same time, this also makes it possible to form a receptacle for the printed circuit board carrying the pressure sensor, so that when the printed circuit board is arranged in the receptacle, one is also formed The first end area of the measuring channel can be contacted with the printed circuit board.
  • the invention further proposes that a temperature sensor is additionally arranged in the connection area.
  • the temperature sensor is used to measure the current temperature in the connection area, which can be used to calculate the current air density.
  • the air density in turn serves to calculate the volume flow of the blower, which in combination with the negative pressure generated by the blower enables the current flow resistance of the attachment to be determined.
  • the evaluation and control device is designed to additionally regulate the suction power as a function of a temperature measured by means of the temperature sensor.
  • the evaluation is also adjusted for the temperature-dependent air density, which contributes to optimal control of the suction power of the fan. This is particularly true because the air density and thus also the negative pressure generated by the fan change depending on the temperature.
  • a first absolute pressure measurement is now carried out before the blower is switched on and then a second absolute pressure measurement after the blower is switched on.
  • the first absolute pressure measurement takes place in such a short period of time, for example 300 milliseconds, that the user of the cleaning device registers no delay in switching on the fan.
  • further absolute pressure measurements can be carried out, preferably at regular successive intervals be carried out, for example 10 to 20 times per second.
  • the negative pressure generated by the fan is determined from the respective absolute pressure determined when the fan is running and the first absolute pressure measured when the fan is switched off.
  • the electrical power consumed by the blower is determined, which is done regularly with the aid of a measurement of the current and the voltage required by the blower.
  • the speed of the fan is also measured. All measured values, ie both the vacuum, the blower power and the speed of the blower are included in the determination of the flow resistance of the front attachment.
  • the flow resistance of the attachment device is noticeable to the user of the cleaning device as a pushing force that has to be used to move the cleaning device or the attachment device over the surface to be cleaned. With a very high flow resistance, it is only possible for the user to guide the cleaning device or the front device over the surface to be cleaned with great effort. This goes hand in hand with a low volume flow through the fan and thus also a low suction power.
  • the measurement data are then compared with known fan characteristics of the fan, from which the volume flow occurring with the respective flow resistance and the pressure difference can be derived.
  • the currently measured suction power is regulated so that the best possible cleaning result is achieved.
  • the speed of the fan and / or the fan power can be varied to regulate the suction power.
  • the suction power is preferably regulated to a constant amount.
  • blower output cannot be increased further when a defined maximum flow resistance of the attachment is reached. This ensures maximum power consumption in view of the flow resistance that arises. About one corresponding maximum flow resistance, the performance of the blower cannot be increased to increase the volume flow.
  • the maximum permissible flow resistance and thus also the pushing force to be used to move the front attachment can be provided, for example, at 20 N. This serves to protect the fan from overloading.
  • the flow resistance of the attachment device currently used is additionally determined as a function of a temperature currently measured in the connection area.
  • the inclusion of the currently measured temperature enables an optimal cleaning result to be achieved with the lowest possible flow resistance.
  • a fill level of a filter arranged in a suction area of a blower be determined by comparing the determined flow resistance of the attachment with reference values which are each assigned to a certain fill level of the filter.
  • empirical characteristic curves or characteristic values for different operating modes or suction power levels are stored, which are each assigned to a specific fill level of the filter. Irrespective of the current fill level of the filter, the suction power should preferably also be kept constant.
  • the cleaning device can be operated by the user using a selection device, for example a slide switch.
  • a first position of the slide switch is assigned, for example, to an automatic operation of the cleaning device.
  • the evaluation and control device automatically controls the vacuum in view of the determined required fan power to achieve a certain suction power or a certain volume flow.
  • power levels with a constant blower power can be provided, for example a power level with a constant blower power of 50 W and a further power level with a higher blower power of 300 W.
  • an additional power level can be provided as the maximum power level.
  • the blower power can be controlled as a function of a detected floor covering, for example hard floor or carpet, for example 700 W for cleaning carpets and 450 W for cleaning hard floors.

  • the control element 16 has a slide switch 17 and a button 18. In detail, the slide switch 17 enables four different positions, to which four different operating modes are assigned.
  • an automatic mode of the cleaning device 1 can be set.
  • the cleaning device 1 regulates an output of the blower 2 automatically as a function of the negative pressure generated by the blower 2 in order to achieve a specific suction power, ie a specific volume flow through the front unit 7.
  • a maximum value for the blower power required is provided in order to protect the blower 2 against an overload.
  • the performance of the blower 2 cannot be increased further beyond this maximum value.
  • the maximum value of the blower power can, for example, be designed for a maximum flow resistance of the front attachment 7 of 20 N. This flow resistance corresponds to the maximum pushing force that must be applied in order to guide the attachment 7 over the surface to be cleaned.
  • the relationship between the negative pressure generated by the blower 2, the volume flow through the front attachment 7 and the pushing force or the flow resistance of the front attachment 7 can be seen from the characteristics of the blower 2 for the attachment 7 currently in use.
