The invention relates to a household electric vacuum cleaners with suction, high serviceability and maintenance.

Known control system power cleaner [1] which includes a universal commutator motor, electronic speed controller, several permanent supletoria engines, working in vacuum cleaners at a considerable speed, due to the presence of brush-collector node, have low technical performance, which is the main factor determining the transition in the current and future systems for induction motors with squirrel-cage rotor.

Known control system cleaner [2] contains the asynchronous motor, the sensor resistance of the air tract and adjustable according to the signal of the frequency Converter. The engine speed in this case is set lower in comparison with existing vacuum cleaners, which does not allow the user to set favorable absorption and leads to waste of energy. This management system cleaner does not respond to gradual fill the bag or smooth overlap of the openings of the suction tube, because the scheme is built on the measurement of peak loads that effectively only when driving the intake tract.

The closest present invention is a control system cleaner [3], which contains serially connected frequency Converter, through the current sensor coupled with wypr the same speed sensor and the start button. It introduced successively United trigger, half-wave rectifier, and the power set the power, the elements of the comparison integrator and stromsoe link. Output estranho link is connected to the input of the regulation of the amplitude of the supply voltage of the frequency Converter. Connected in series functional Converter, an adder, and the scaling amplifier is connected to the input of the frequency control voltage of the frequency Converter. The system has a unit initial speed, two adder, three of the scaling amplifier and shaper reset trigger run.

A large number of different electronic controls creates the possibility of misalignment of the sensor signal feedback to the control system. This leads to the emergence of oscillatory processes in the management system, which reduces the reliability of the system. In addition, the use of electronic components increases the cost of the product. The presence of secondary power sources increases the energy consumption, resulting in reduced efficiency of the system.

The objective of the invention is to enhance reliability of operation of the control system due to isklucheniia the number of electronic elements, which depends on the level of the mains voltage; increasing the efficiency of the management system.

The problem is solved by a control system cleaner containing serially connected frequency Converter, the power input of which is through a smoothing filter connected to the outputs of the rectifier mains supply and the induction motor, the output shaft of which is mechanically interlocked with the fan of the vacuum cleaner, and startup. Moreover, the frequency Converter is made in the form of self inverter power input of which is connected to the rectifier through a smoothing filter. The windings of the inverter is connected to the outputs of the system startup, the inputs of which are connected to the outputs of the smoothing filter.

To explain the merits of the invention in Fig. 1 is a diagram of the control system.

The control system includes an adjustable rectifier 1, the output of which through a smoothing filter 2 is connected to the input of the power of self inverter 3. To the output of the smoothing filter 2 connected starting system 4, the output of which is connected with the windings of disturbing the inverter 3. Induction motor 5, the output shaft of which is mechanically interlocked with the fan is the PTOP 3 through the system run 4 served the starting pulse and the inverter starts to work: open the transistors and the primary and synchronizing windings of transformers begins to leak current. The cores of transformers turn out to be in saturation mode. The switching transistor is in saturation of transformers. The switching frequency of the transistors is determined by the number of turns of the primary winding and the voltage level of power.

When the load changes air suction device, for example, the clogging of the suction pipe of a vacuum cleaner, changing the dust of the workpiece and so on, changes the power consumption of a drive motor 5 and the current in the power circuit. In this regard, changes the voltage drop on the upstream circuits (controlled rectifier 1, a smoothing filter 2), which leads to a change in the constant voltage at the input of the self-excited inverter 3. The frequency of the inverter circuit is directly proportional to the level of DC voltage at its input. Thus, during the driving of the suction pipe reduces the load of the motor 5, decreases the current in the power circuit unit and decreases the voltage drop across the controlled rectifier 1. Increasing the voltage at the input of the self-excited inverter 3, and the frequency of the circuit. Increasing the rotational speed of the engine 5 and the suction power of the unit that allows list and capacity) are selected in such a way to provide sufficient amount of increase in the suction power of the unit. When smooth load changes at the inlet of the suction unit, the compensation process of its change proceeds similarly, and excessive energy consumption and noise level of the unit in this case is minimal. In the whole range of load change ratio of the magnitude of the voltage on the engine 1 to the generation frequency of the inverter 3 is constantly (U/f= const), the current and the torque on the motor shaft are almost unchanged. No special sensors and feedback circuit simplifies the structure of the device and eliminates the possibility of oscillatory processes in the control system of the frequency Converter, which increases the reliability of the device.

Management system cleaner containing serially connected frequency Converter, the power input of which is through a smoothing filter connected to the rectifier output, and induction motor, the shaft of which is mechanically interlocked with the fan of the vacuum cleaner, as well as system startup, characterized in that the frequency Converter is made in the form of self inverter windings of which are connected to the outputs of the system startup and inputs systems
