Description

Technical field:

[0001] The invention relates to a rotary waterfall pulsator washing machine, which belongs to the technical field of household appliances. Background technology:

[0002] The existing pulsator washing machine that realizes the cyclone washing function drives the drain valve through dual motors. One motor is used to switch between the washing and dehydration states, and the other motor is used to switch between dehydration and drainage. In other words, in order to realize the cyclone washing function, a driving motor is added to the original traditional pulsator washing machine. The structure becomes complicated, and the cost of an additional motor is increased. In addition, the more electrical components there are, the greater the probability of error.

[0003] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Summary of the invention:

[0004] The present invention is to solve the problems existing in the above-mentioned prior art and provide a pulsator washing machine with a cyclone and waterfall washing, which replaces the existing double-motor control by controlling double strokes with a single motor.

[0005] The technical solutions adopted in the present invention include: a rotary waterfall pulsator washing machine, comprising a drain valve body, a first drain valve core, a second drain valve core, a bellows, a compression spring, a tension spring, a valve cover, a connecting arm and a drain valve pull rod, the drain valve body and the valve cover are installed together, the bellows are installed in the drain valve body, the compression spring is installed on the first drain valve core to press the bellows in the drain valve body through the compression spring, the drain valve pull rod is installed in the first drain valve core, the second drain valve core is integrally formed on the outer surface of the end of the drain valve pull rod away from the valve cover installation position, the second drain valve core moves inside the first drain valve core, the tension spring is installed in the drain valve pull rod, one end of the tension spring is clamped together with the drain valve pull rod, and the other end of the tension spring extends out of the drain valve body and is clamped together with the connecting arm.

[0006] Furthermore, a boss portion is formed on the end protrusion of the inner surface of the bellows away from the valve cover installation position.

[0007] Furthermore, a flange portion abutting against the boss portion is formed on the terminal protrusion of the first drain valve core away from the valve cover installation position, and the flange portion abuts against the surface of the boss portion facing away from the valve cover installation position.

[0008] Furthermore, the first drain valve core includes an integrally formed outer ring portion and an inner ring portion spaced apart from the outer ring portion, and the compression spring is installed between the outer ring portion and the inner ring portion on the first drain valve core.

[0009] Furthermore, an internal thread is formed on the valve cover, and an external thread is formed on the drain valve body at a position opposite to the valve cover, and the valve cover and the drain valve body are installed together through the cooperation of the internal thread and the external thread.

[0010] Furthermore, the second drain valve core is assembled concentrically with the first drain valve core.

[0011] The present invention has the following beneficial effects: the pulsator washing machine of the present invention uses one motor to drive two strokes instead of two existing motors to independently control two strokes. The single motor structure is simpler and easier to manufacture. In addition, one motor is reduced, which greatly reduces the product cost. Description of the drawings:

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] The pulsator washing machine with a whirlpool washing machine of the present invention comprises a drain valve body 1, a first drain valve core 2, a second drain valve core 3, a bellows 4, a compression spring 5, a tension spring 6, a valve cover 7, a connecting arm 8 and a drain valve pull rod 9.

[0019] An internal thread is formed on the valve cover 7, and an external thread is formed on the drain valve body 1 at a position opposite to the valve cover 7. The valve cover 7 and the drain valve body 1 are installed together through the cooperation of the internal thread and the external thread.

[0020] The bellows 4 is installed in the drain valve body 1 , and a boss portion 40 is formed on the inner surface of the bellows 4 at the end thereof away from the installation position of the valve cover 7 .

[0021] The first drain valve core 2 includes an integrally formed outer ring portion 20 and an inner ring portion 21 spaced apart from the outer ring portion 20. The end protrusion of the first drain valve core 2 away from the installation position of the valve cover 7 is formed with a flange portion 22 abutting against the boss portion 40. The flange portion 22 abuts against the surface of the boss portion 40 facing away from the installation position of the valve cover 7.

[0022] The compression spring 5 is installed between the outer ring portion 20 and the inner ring portion 21 of the first drain valve core 2. The compression spring 5 presses the bellows 4 against the drain valve body 1.

[0023] The drain valve pull rod 9 is installed in the first drain valve core 2, and the second drain valve core 3 is integrally formed on the outer surface of the end of the drain valve pull rod 9 away from the installation position of the valve cover 7. The second drain valve core 3 is concentrically assembled with the first drain valve core 2, and the second drain valve core 3 moves inside the first drain valve core 2.

[0024] The tension spring 6 is installed in the drain valve pull rod 9, and the end of the tension spring 6 close to the flange portion 22 is clamped together with the drain valve pull rod 9, and the other end of the tension spring 6 extends out of the outside of the drain valve body 1 and is clamped together with the connecting arm 8.

[0025] The working principle of the pulsator washing machine with a waterfall wash function of the present invention is as follows: a motor (not shown) is connected to the outer side of the connecting arm 8. Under normal conditions, the motor does not work, the clutch is in a disconnected state, the pulsator rotates, and the inner drum does not rotate. This is a normal washing state. After the motor works, the motor drives the drain valve pull rod 9 to have two strokes. The drain valve pull rod 9 is pulled by the connecting arm 8 to perform the first stroke. In this stage, the drain valve pull rod 9 drives the second drain valve core 3 to move to the left. The second drain valve core 3 does not drive the first drain valve core 2. At this time, the first drain valve core 2 is not opened and does not drain water. However, this stroke opens the clutch ratchet structure, so that the clutch is in a connected state, and the inner drum rotates at high speed together with the pulsator. The water that escapes will not be discharged. Under the action of centrifugation, it spirals up and finally sprays out through the top, realizing the waterfall wash function. After the whirlpool washing is completed, the drain valve rod 9 is pulled by the connecting arm 8 to perform the second stroke, and the second drain valve core 3 is continuously pulled to the left, driving the first drain valve core 2, thereby driving the bellows 4 to move to the left, and the drain valve is opened. The water in the tub will no longer spiral up, but will be directly discharged to realize the drainage function. At this point, the whirlpool washing function driven by a single motor with a double stroke is completed.

[0026] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
