Embodiment 1

[0035] In this example, if figure 1 As shown, the pump body 1 of the AC washing electric pump is connected with the water cup 2 in the dishwasher. Specifically, the water inlet 11 of the pump body 1 is connected to the cylindrical flow channel 21 of the water cup 2, and the pump body 1 obtains water supply directly from the water cup 2, thereby reducing water flow loss and pressure loss without connecting pipes.

[0036] Such as figure 2 As shown, the stator winding of the motor in the AC washing electric pump includes the first main phase winding M1, the second main phase winding M2 and the auxiliary phase winding A, the first end of the first main phase winding M1 is connected to the second main phase winding M2 The first end of A and the first end of the auxiliary phase winding A are connected to the high-speed power supply switch K in the dishwasher H, the second end of the first main phase winding M1 is connected to the ground wire COM, and the second end of the second...

Embodiment 2

[0052] In this embodiment, with Embodiment 1 figure 1 As shown, the pump body 1 of the AC washing electric pump is connected with the water cup 2 in the dishwasher. Specifically, the water inlet 11 of the pump body 1 is connected to the cylindrical flow channel 21 of the water cup 2, and the pump body 1 obtains water supply directly from the water cup 2, thereby reducing water flow loss and pressure loss without connecting pipes.

[0053] Such as Figure 5 As shown, the stator winding of the motor in the AC washing electric pump includes the first main phase winding M1, the second main phase winding M2, the third main phase winding M3 and the auxiliary phase winding A, the first end of the first main phase winding M1 The high-speed power supply switch K in the dishwasher is commonly connected with the first end of the second main phase winding M2 and the first end of the auxiliary phase winding A H , the second end of the first main phase winding M1 is connected to the groun...

Abstract

The invention belongs to the technical field of dish washing machine control, and provides a dish washing machine, and a speed adjustment control method and system for an alternating current washing electric pump of the dish washing machine. A pump body of the alternating current washing electric pump in the disk washing machine is connected with a water cup; when a motor stator winding in the alternating current washing electric pump comprises two main-phase windings and an auxiliary-phase winding, a high-speed power supply switch and a low-speed power supply switch are controlled to be switched on alternatively, so that the alternating current washing electric pump runs alternatively at high revolving speed and low revolving speed; when the motor stator winding in the alternating current washing electric pump comprises three main-phase windings and an auxiliary-phase winding, the high-speed power supply switch, an intermediate-speed power supply switch and the low-speed power supply switch are circularly controlled to be sequentially switched on, so that the alternating current washing electric pump circularly runs sequentially at high revolving speed, intermediate revolving speed and low revolving speed; when the cost is reduced, the noise and the energy consumption of the alternating current washing electric pump are reduced through alternative running of the alternating current washing electric pump at high and low revolving speeds or circularly running in sequence in high, intermediate and low revolving speeds.

Description

technical field [0001] The invention belongs to the technical field of dishwasher control, and in particular relates to a dishwasher and an AC washing electric pump speed regulation control method and system thereof. Background technique [0002] At present, as a kind of tableware washing equipment, dishwashers are widely used in restaurants, restaurants, homes and other places that need to use various tableware to wash tableware in batches, improve the efficiency of tableware washing, and can also remove bacteria on tableware , beneficial to people's health. [0003] Existing dishwashers usually use AC single-speed electric pump technology, and the speed of the washing electric pump is designed to operate at a single high speed. More than 2800r / m (rotation / minute), and when the 60Hz AC power supply is used, the rotating speed of the washing electric pump is designed to be above 3200r / m. When the electric washing pump operates at high speed, its water flow pressure is high...
