A control method 1 of a pulsator washing machine according to an embodiment of the present invention is described below with reference to the accompanying drawings.
In some embodiments of the present invention, as shown in fig. 1 to 2, a control method of a pulsator washing machine according to an embodiment of the present invention.
Specifically, the operation state of the pulsator washing machine 1 further includes a washing state in which the inter-tub cleaning device is controlled to flush at least one of the outer wall of the inner tub 300 and the inner wall of the outer tub 200 in at least two of the water supply state, the washing state, the water discharge state, and the dehydration state. Thus, the inter-tub cleaning device can clean the tub at least in the water inlet state and the washing state, and since a large amount of foam and contaminants are present between the inner tub 300 and the outer tub 200 in the washing state, the inter-tub cleaning device can timely wash the foam residue and contaminants of the inner tub 300 and the outer tub 200, and when the water level is low, the inner tub 300 starts to rotate, and water impact is generated by centrifugal force, thereby further improving the self-cleaning capability of the pulsator washing machine 1.
More specifically, the inter-tub cleaning device is controlled to flush at least one of the outer wall of the inner tub 300 and the inner wall of the outer tub 200 in at least two of the water inlet state, the water discharge state, and the dehydration state. Thus, the inter-tub cleaning device can clean the tub in the water inlet state, the washing state, and the dehydrating state, and since the inner tub 300 rotates at a high speed in the dehydrating state, the water current and the wall of the inner tub 300 generate a strong force, the self-cleaning effect of the high pulsator washing machine 1 is better.
Specifically, the user may select one state or two states or three states of the water inlet state, the washing state and the dewatering state to clean at least one of the outer wall of the inner tub 300 and the inner wall of the outer tub 200, or may select a self-cleaning process alone, which facilitates improving flexibility of self-cleaning of the pulsator washing machine 1 and improving comfort of the user.
Alternatively, the control driving device 400 drives the inner tub 300 to rotate while the inter-tub cleaning device flushes at least one of the outer wall of the inner tub 300 and the inner wall of the outer tub 200. Therefore, when the inner barrel 300 is washed, the water flow between the inner wall of the outer barrel 200 and the outer wall of the inner barrel 300 has stronger impact force through the rotation of the inner barrel 300, so that washing and washing can be carried out up and down back and forth, and the self-cleaning capability of the pulsator washing machine 1 can be improved.

One end of the water inlet assembly 520 is in communication with the cleaning ring 510 and the other end is in communication with an external water source. Specifically, the shower diameter of the flushing port 511 is small. This facilitates the water flow sprayed from the washing outlet 511 to impact the area between the outer tub 200 and the inner tub 300, improving the washing effect of the cleaning ring 510. Meanwhile, since one end of the water inlet assembly 520 is communicated with the cleaning ring 510 and the other end is communicated with an external water source, the cleaning ring 510 can also perform washing and rinsing on at least one of the inner wall of the outer tub 200 and the outer wall of the inner tub 300 when the inner tub 300 is stationary, for example, washing and rinsing can also be performed in the water inlet state, thereby further reducing the self-cleaning limitation condition of the pulsator washing machine 1.
More specifically, as shown in fig. 1, the cleaning ring 510 is provided at an upper end of the outer tub 200 and is located inside the outer tub 200 in a horizontal direction (the up-down direction is shown by an arrow a in fig. 1). Therefore, the washing of the cleaning ring 510 on at least one of the inner wall of the outer barrel 200 and the outer wall of the inner barrel 300 from the upper end is facilitated, the washing of the cleaning ring 510 is more sufficient and effective under the action of gravity, and the cleaning ring 510 is connected with the water inlet assembly 520 to facilitate the arrangement of the cleaning ring 510. Meanwhile, the cleaning ring 510 is disposed between the outer tub 200 and the inner tub 300, which further facilitates the cleaning ring 510 to wash at least one of the inner wall of the outer tub 200 and the outer wall of the inner tub 300, thereby preventing water from entering between the outer tub 200 and the cabinet 100.
Alternatively, as shown in fig. 1, the flushing port 511 is provided toward the outer wall of the inner tub 300. This is convenient for the outer wall of the inner barrel 300 to be washed and flushed more efficiently by the cleaning ring 510, and is convenient for ensuring the washing effect of the outer wall of the inner barrel 300. Therefore, the cleaning between the inner barrel 300 and the outer barrel 200 is convenient, the bacteria and dirt residue are avoided, the foam and the detergent on the inner barrel 300 can be removed in time, the resistance received when the inner barrel 300 rotates is reduced, and the running efficiency of the inner barrel 300 is improved.
Specifically, as shown in fig. 1, the one end of the water inlet assembly 520 is directly connected to the cleaning ring 510 and the other end is exposed from the outer surface of the case 100 to be connected to an external water source. This facilitates the connection of the water inlet assembly 520 with an external water source, further facilitating the wash washing of the cleaning ring 510 with at least one of the inner wall of the outer tub 200 and the outer wall of the inner tub 300 while the inner tub 300 is stationary.
More specifically, as shown in fig. 1, the water inlet assembly 520 includes a water inlet pipe 521 and an on-off valve 522, one end of the water inlet pipe 521 is exposed to the outer surface of the tank 100 and the other end is directly connected to the cleaning ring 510. An on-off valve 522 is connected to the inlet pipe 521 to open or close the inlet pipe 521, and the on-off valve 522 is electrically connected to the controller. The operation of the water inlet assembly can be controlled by the on-off valve 522 to control the water inlet condition of the cleaning ring 510.
Further, the water inlet assembly 520 further comprises a detergent box connected to the water inlet pipe 521 and adapted to contain detergent of the washing machine therein. Therefore, a user can put the washing machine cleaning agent into the cleaning agent box, and the washing machine cleaning agent can flush and wash at least one of the inner wall of the outer barrel 200 and the outer wall of the inner barrel 300 through the cleaning ring 510 and water flow when water enters, so that the washing effect of the cleaning ring 510 on at least one of the inner wall of the outer barrel 200 and the outer wall of the inner barrel 300 is further improved.
Alternatively, as shown in fig. 2, the flushing port 511 is plural, and the plural flushing ports 511 are provided at intervals along the circumferential direction of the cleaning ring 510. Specifically, the shower diameter of the flushing port 511 is small. Therefore, water flow can be uniformly sprayed from the plurality of washing openings 510 to impact the area between the outer barrel 200 and the inner barrel 300, the washing effect of the cleaning ring 510 is further improved, meanwhile, the stress of the cleaning ring 510 is more uniform, and the structural stability of the cleaning ring 510 is improved.
Further, a washing button is provided on the control panel, and when the washing button is operated, the controller controls the on-off valve 522 to be opened and controls the driving device 400 to rotate the inner tub 300. Therefore, when the inner barrel 300 is washed, the water flow between the inner wall of the outer barrel 200 and the outer wall of the inner barrel 300 has stronger impact force through the rotation of the inner barrel 300, so that washing and washing can be carried out up and down back and forth, and the self-cleaning capability of the pulsator washing machine 1 can be improved.
Alternatively, the spin-off state on-off valve 522 of the pulsator washing machine 1 is opened. Thus, when the pulsator washing machine 1 performs a dehydration operation, the cleaning ring 510 may wash at least one of the inner wall of the outer tub 200 and the outer wall of the inner tub 300 to remove foam and detergent remaining on the tub, thereby improving the operation efficiency of the inner tub 300 and further improving the self-cleaning capability and the dehydration capability of the pulsator washing machine 1.
Specifically, in the water inlet process, the water flow is controlled to enter the space between the inner barrel and the outer barrel through the computer board, the inner barrel and the outer barrel are washed, the last washing residue is reduced, and foreign matters and breeding bacteria influence the clothes to be washed. In the drainage process, a large amount of foam and pollutants are arranged between the inner barrel and the outer barrel, the water inlet valve is controlled by the computer board to feed water, and foam residues and pollutants of the inner barrel and the outer barrel are washed, so that the effect of cleaning the inner barrel is achieved, and the rinsing performance and the dewatering performance are improved. When the computer board controls the drainage to a low water level, the inner barrel starts to rotate, water flow from bottom to top generated by centrifugal force impacts the water inlet valve to feed water to generate water flow impact from top to bottom, so that the inner barrel rotates at a high speed in the dehydration process of the cleaning barrel, the water inlet valve is controlled to feed water at the moment, the water flow and the wall of the inner barrel generate strong acting force, and the cleaning force is stronger.
