Abstract
The utility model relates to a directly driven washing machine which comprises a motor 1, a clutch 2, an impeller 3, a roller 4, an outer shell 5 and a control system. The utility model is characterized in that the motor 1 as a three-phase asynchronous squirrel cage type motor is used for directly driving the impeller 3 or the roller 4 by the clutch 2 for washing or dewatering and drying. The control system comprises a CPU motherboard 6, a switching power supply 7, an inverter 8, a motor 8, a CT control module 9 and a sensor 10. Due to the adoption of the three-phase asynchronous squirrel cage type motor having low cost, high efficiency and long service life and high precise intelligent frequency conversion servo technology, the washing machine has the advantages of super energy saving, super silence, low cost, high performance and no environmental protection problem.
Description
The utility model relates to the washing machine of a kind of washing machine, particularly a kind of direct driving.
At present, domestic and international various washing machines are divided into two classes, and a kind of is conventional washer, and it after pulley decelerates, drives impeller or cylinder do washing or spin-dry by clutch by single-phase asynchronous capacitor motor.Another kind is directly to drive variable-frequency washing machine, and it is by the outer rotor dc brushless motor or IPM alternating current asynchronous ferromagnetic motor directly drives impeller by clutch or cylinder is done washing or spin-dry.
When conventional washer was 50Hz or 60Hz at family's electrical network, in washing machine starting moment, because of no soft start function, motor jumped to rated speed from inactive state moment, and the electric current of motor, torque suddenly change, and caused to the influence of electrical network with to the impact of reductor.For the transient starting electric current that overcomes motor is too big, motor is designed to high resistance type more, to reduce starting current.Because the motor impedance is too big, though starting current has lowered, electric efficiency also descends greatly, on average only is 30%, and motor easily generate heat, fragile; Because characteristic is very soft, clothes descends once many rotating speeds that can make, or because of long-time stall burns motor, in addition, the mechanicalness noise electromagnetic noise is big, and vibration is big, and is fragile.This washing machine can not adapt to the needs of the modern life far away.
Realized energy-conservation, mute function though directly drive variable-frequency washing machine,, outer rotor dc brushless motor manufacturing technique complexity is difficult to realize producing in enormous quantities; IPM alternating current asynchronous ferromagnetic motor is except having with the same manufacturing technique complexity of outer rotor dc brushless motor, and its weight and volume all increases greatly; Two kinds of motors all have cost height, control system complicated problems; After these two kinds of motors were scrapped, the separation difficulty of permanent-magnet material (Nd-Fe-B), iron copper, aluminium did not meet international household electrical appliances environmental law.
The purpose of this utility model is to overcome the deficiencies in the prior art and defective, a kind of washing machine of direct driving is proposed, adopt low cost, high efficiency, long-life phase asynchronous MC and high-accuracy intelligent frequency conversion servo techniques, make super energy-conservation, super-silent, low-cost, the high-performance of the function of doing washing and do not have the environmental protection problem.
The purpose of this utility model is achieved through the following technical solutions.
A kind of washing machine of direct driving, it comprises motor, clutch, impeller, cylinder, shell and control system, it is characterized in that motor is phase asynchronous MC.
The invention has the advantages that it has adopted low cost, high efficiency, long-life phase asynchronous MC, the overall efficiency of this motor reaches more than 85%, and with its distinctive high-accuracy intelligent frequency conversion servo techniques, make super energy-conservation, super-silent, low-cost, the high-performance of laundry function and do not have the environmental protection problem, substantially overcome the shortcoming of prior art, and represented the developing direction of following household electrical appliances.

Fig. 2 is the schematic diagram of the washing machine of a kind of direct driving of the present invention;
Fig. 3 is a control system schematic diagram of the present invention.
Embodiment:
In conjunction with the accompanying drawings 2 and accompanying drawing 3 introduce embodiment.
A kind of washing machine of direct driving, with 4.5 kilograms of washing machines is example, it comprises motor 1, clutch 2, impeller 3, cylinder 4, shell 5 and control system, motor 1 is phase asynchronous MC, under the Based Intelligent Control of control system, it directly drives impeller 3 or cylinder 4 by clutch 2, washs or spin-dry.
The rotating speed of motor 1 can be by control system parameter setting between 10rpm～880rpm, and can set arbitrarily, thereby realize requirements such as " gentlely wash, generally wash, wash by force, big thing wash " by software programming.
Control system comprises cpu motherboard 6, Switching Power Supply 7, inverter 8, motor 1, CT control module 9 and sensor 10 (CT control can be chosen any one kind of them with the sensor feedback control mode).
The motor 1 of this washing machine after various sensor signals are handled, according to the user the various operating and settings on the guidance panel or by family outside after the internet reservation, under the control of control system, start and finish the laundry task.The speed setting of motor 1 for gentle wash 100rpm, generally wash 150rpm, wash 180rpm, spin-dry 800～880rpm by force, controls such as the difference laundry speed of washing machine, intensity can be carried out FEEDBACK CONTROL by sensor 10 or CT control module 9, thereby realize super-silent, super energy-conservation, high-precision intelligent control.Noise＜the 40dB of this washing machine, the motor overall efficiency reaches more than 85%, realized soft start function, reduce mechanical loss, more energy-conservation more than 30% than existing direct driving washing machine, and greatly reduce cost, be significantly less than the existing price that directly drives washing machine, and performance better, more perfect, loss is little, the life-span is long, and does not have the environmental protection problem.
