LAUNDRY SHNTSHFUGA.

The utility model relates to a machine for spinning laundry and can be used in laundries.

A well-known laundry centrifuge comprising a frame closed by side panels / w and carrying an electric motor mounted on a / yrs, a perforated working drum, a shaft of which is located in the intermediate support, a smooth acceleration device and a drum closing mechanism, an electric motor control device, locking devices, a loading hatch, water collecting pan and drain pipe. Moreover, the assembly that includes the intermediate support bearing the shaft of the perforated working drum and the smooth acceleration and braking device of the drum are made in the form of a friction cam mechanism / see assembly drawing TSTRIFUGA LAUNDRY KP - 240 M 00.00.000 SB. /.

The frictional padding of the fricodon-cam mechanism is very unstable in an environment with high humidity, therefore, the load on the electric motor at the time of starting it is also unstable, i.e. the electric motor operates in very harsh conditions. In addition, the service life of the friction covers is short, and their solution requires partial disassembly of the centrifuge, i.e., the labor / maintenance and repair of the known centrifuge are significant.

Thus, the lack of a well-known laundry centrifuge can be attributed to its low reliability due to the presence of a mechanical friction mechanism, as well as high labor / maintenance and repair costs.

The proposed utility model allows you to increase the reliability of the centrifuge laundry service, and reduce the cost of its maintenance and repair.

The specified technical result is achieved by the fact that in the laundry centrifuge, it contains: a fixed frame, a closed side panel with panels and an electric motor mounted on shock absorbers, a working perforated drum, the shaft of which is located in the intermediate support, a device for smooth acceleration and braking of the drum, an electric motor control device, locking devices , a loading hatch, a water collection tray and a bypass tube, a part of the drum shaft facing the electric motor, a hole in which the electric shaft is rigidly fixed ktrodvigateli, and the motor control device is provided elektronnsh motor shaft speed controller.

The essence of the proposed utility model is illustrated by a schematic drawing, where in FIG. Shows a general view of the proposed centrifuge laundry.

The laundry centrifuge contains a frame I, closed by side panels 2 and carrying an electric motor 4 mounted on shock absorbers 3, a perforated working drum 5, a shaft 6 of which is located in the intermediate support 7, an electric motor control device 4, locking devices 9, a loading Like 10, pallet II for water collection, outlet pipe 12. Part of the shaft 6 facing the electric motor 4, mvieeT hole 13 in which the shaft 14 of the electric motor 4 is rigidly fixed. The control device 8 of the electric motor 4 is equipped with an electronic astota regulator rotation of the shaft 14 of the electric motor 4. The loading hatch 10 is closed from above by the rotary cover 16. If a DC collector motor is used in the centrifuge, the electronic speed controller, during start-up and shutdown, provides a smooth change in the amplitude of the voltage supplied to the electric motor. When using an asynchronous b / phase AC electric motor in a centrifuge, the electronic speed controller, when starting and stopping, provides a direct change in the frequency and amplitude of the voltage supplied to the electric motor.

Laundry centrifuge operates as follows.

Through the loading hatch Yu wet washed linen / Fig. not shown / evenly inserted into the working perforated drum 5. The loading door IQ is closed by a pivoting cover 16, which acts on the locking device 9. The signal from it is supplied to the electric motor control device 8, while the locking device 9 prevents the cover 16 from moving. With the motor starting 4, the electronic regulator 15 of the rotational speed of the electric motor of the control device 8 supplies a voltage to the electric motor with the required parameters. There is a gradual increase in the number of revolutions of the working drum, while the laundry is annealed. The duration of the spin is determined by the amount of processed laundry, scotch / cloth, etc. Water is collected in pan II and / is removed from the centrifuge through the outlet tube 12. With the end of the process, by the speed controller 15, a voltage with a reduced amplitude / frequency, dda of the asynchronous motor / is applied to the electric motor, which ensures smooth braking of the electric motor and drum 5. With a stop drum 5 and turning off the motor 4, the locking device 9 releases the cover 16, i.e., makes it possible to open the hatch 10. The pressed laundry is removed from the drum S through the hatch 10. The centrifuge is ready for repeated I cycle otzhshya linen.

The pilot operation of the centrifuge laundry of the proposed design using a three-phase asynchronous motor mod. AMP90L4 BYZOV S - 2.2 kW. p - 1500 rpm. and electronic speed controller mod. UMPT-3.0, has confirmed a significant increase in centrifuge reliability and a reduction in the cost of maintenance and repair in comparison with the analogue by 3–5 times over the entire life cycle.
