The washing assembly 200 is mounted on the cabinet 110 or the cover plate 120. The washing assembly 200 includes a mode switch 210 and a program controller 220 which are connected to each other. The program controller 220 has at least two switching positions, each of which corresponds to a working mode, and different rotation orientations of the mode switch 210 correspond to different working modes of the stirring impeller type washing machine.
The water level assembly 300 is mounted on the cabinet 110 or the cover plate 120. The water level assembly 300 includes a water level switch 310, a water injection controller 320, an encoder 330 and a water level sensor 340. Both the water level switch 310 and the water injection controller 320 are connected to the encoder 330, the encoder 330 is connected to the water level sensor 340, and the water level sensor 340 faces towards the inner region of the washing tub 130. The encoder 330 is capable of directly or indirectly controlling the water injection controller 320 to stop water injection after the water level sensor 340 detects that the water level in the washing tub 130 reaches a preset water level, wherein the water level switch 310 can adjust the preset water level through different rotation orientations.
According to the above embodiments of the present application, the above-mentioned configurations can combine the fully automatic characteristics of the impeller washing machine with the convenience of mechanical operation, that is to say, the washing mode of the washing machine is controlled by the washing assembly 200, and the water level is controlled by the water level assembly 300. Specifically, the water level can be adjusted through the water level switch 310, and with the cooperation of the encoder 330 and the water level sensor 340, the water level can be controlled more accurately, and the program controller 220 can better control the washing program and time, which greatly improves the operability and the accuracy of water volume, and makes the operation clear at a glance to the user. The above-mentioned configurations not only solve the semi-automatic operation problem of the double tubs, but also are simple and clear in the program selection. The design of a stirring seat 134 of this stirring washing machine can make the clothes less entangled and have a higher degree of cleanliness through certain control(s). The embodiments of the present application have the beneficial effects of making the operation of the washing machine more convenient, the water level control more sensitive, and the cleanliness degree higher.
It should be noted that the program controller 220 may be set with three gears, that is to say, the program controller 220 is configured with three programs, each program may be subdivided into more segments, and the working mode, i.e., the washing mode, may be changed via the mode switch 210. The change of the water level gear, that is, the change of the stirring frequency, may be changed according to the encoder 330. The encoder 330 may be set with seven gears, wherein gears 1-4 have fast stirring frequencies, and gears 5-7 have slow stirring frequencies. The water level may be adjusted manually according to the amount of clothes. The program controller 220 may be a mechanical program controller 220 or other types of program controller 220.
Further, the washing water levels indicated on the water level switch 310 are MIN, MID, and MAX clockwise from left to right, and a corresponding water level may be selected by turning the switch to the corresponding gear. Program selection: there are 3 programs on a control panel for selection, which are HEAVY, NORMAL, and GENTLE. Each program consists of three segments: wash, rinse, and spin, and in different programs, the repetition times of the “rinse” and the “spin” are different. With the switch being turned to a functional position of a corresponding program, a corresponding function corresponding to the program is selected. For example, if the switch is turned to the area of the “wash” of the HEAVY program, the washing program of the HEAVY program is selected. After the program selection is completed, the program is started when the switch is pulled up, and is paused when the switch is pressed.

Based on the above embodiments of the present application, the above-mentioned configuration may make the washing process smoother, ensure that only the washing process is to be performed after the water level reaches the preset water level, and improve the washing efficiency.
It should be noted that the water injection controller 320 may be a water injection pump or a water injection valve, and water injection may be performed or stopped by activation or deactivation of the water injection pump or the water injection valve. At the same time, the following drainage pump 113 may be combined to discharge excess water, so as to discharge part of the water in time in case that the water level in the washing tub 130 is higher than the preset water level. Meanwhile, a threshold may be set, for example, if the water level is higher than 0.5 L, it is no need to perform the discharge process, and may directly perform the washing process. When the water level in the washing tub 130 is much lower than the preset water level, the water injection pump may be controlled to inject water so as to ensure there are sufficient water.

Based on the above embodiments of the present application, with the above-mentioned configuration, the relative rotation between the inner tub 131 and the outer tub 132 drive the clothes in the washing tub 130 to move, thereby ensuring the washing effect. The outer tub 132 suspended within the cabinet 110 can improve the connection stability between the outer tub 132 and the cabinet 110. Four suspension rods 137 may be provided as required to further improve the connection stability.
In some embodiments, a connecting pipe 135 and a tractor 136 are provided at the bottom of the outer tub 132, wherein the connecting pipe 135 is connected with the drainage pump 113 arranged on the cabinet 110, and the tractor 136 is respectively connected to the drainage pump 113, the washing assembly 200 and the water level assembly 300. An outer ring 133 is provided at the top portion of the outer tub 132, and the outer ring 133 at least partially covers the upper region of the inner tub 131.
Based on the above embodiments of the present application, the connecting pipe 135 may be connected with the drainage pump 113 to improve the drainage efficiency of the washing machine (referring to a stirring impeller type washing machine, similar reference exists in the other parts of the description). The outer ring 133 may cover the upper region of the inner tub 131 so as to avoid direct contact of human hands with the rotating inner tub 131, thereby improving the safety of the washing machine.
It should be noted that the tractor 136 has three functions of traction, holding, and releasing. The working principle of the cooperation between the tractor 136 and each program of the washing machine may be as follows: when a control circuit board issues a draining (or drying) command, a traction motor and an anti-reverse electromagnet in the tractor 136 are simultaneously energized to work, wherein the motor draws a steel wire (or rack) into the tractor 136 through a gear set, and the steel wire thus pulls the drain valve to drain water, and, with a mechanical linkage mechanism, makes the ratchet and the pawl of a clutch 170, which having both washing and drying functions, be separated (at the same time, a locker of the spin-drying tub is released), to prepare for the synchronous rotation of the impeller and the inner bucket 131 during the next drying process (a square wire spring in the ratchet tightly hugs the impeller shaft and the shaft of the inner tub 131 together); the anti-reverse electromagnet is energized to attract its linkage mechanism to bounce up, so as to ensure that the motor rotates in one direction to draw the steel wire, and when these have been properly performed, the motor is deenergized via a limit switch in the tractor 136, and thus the rotation of the motor is stopped, while the electromagnet is continuously energized, attracting its linkage mechanism to tightly lock the steel wire so as to overcome the reverse tension of the return spring of the drain valve, maintaining the original working state. When the draining (drying) program is completed, a command from the control circuit board 111 causes the power off of the tractor 136, and the anti-reversal mechanism inside it is released, and the traction steel wire is pulled out under the action of the return spring of the drain valve, so that the drain valve is closed, and the linkage mechanism synchronously allows the pawl to mesh with the ratchet of the clutch 170 (the impeller shaft is disengaged from the shaft of the spin-drying tub, so that the clutch 170 returns to the washing state).
In some embodiments, a control circuit board 111 and a capacitor 112 are arranged inside the cabinet 110, wherein the control circuit board 111 is connected to the capacitor 112, and the control circuit board 111 is electrically connected to both the washing assembly 200 and the water level assembly 300 to control the washing assembly 200 and the water level assembly 300 to work.

The work of the washing assembly 200 and the water level assembly 300 may be controlled by the control circuit board 111, and the control of the control circuit board 111 may be assisted by the mode switch 210 and the water level switch 310.
It should be noted that the capacitor 112 may be connected to a driving member 150 described below, which may reduce the difficulty of activating the driving member 150, and the driving member 150 may be a motor.
In some embodiments, the washing machine body 100 further includes a driving member 150, a transmission assembly 160, and a clutch 170. The driving member 150 is mounted in the cabinet 110, under the outer tub 132; the transmission assembly 160 has an input end connected with the driving member 150 and an output end; the clutch 170 is connected with the inner tub 131, and can drive the inner tub 131 to rotate relative to the outer tub 132, and one side of the clutch 170 away from the inner tub 131 is connected with the output end.
The clutch 170 has a first connecting member and a second connecting member that can be connected or separated, and the clutch 170 has a connected state and a separated state. In the connected state, the first connecting member and the second connecting member are connected as a whole, and the clutch 170 can transmit the torque of the output end to the inner tub 131; in the separated state, the first connecting member and the second connecting member are separated from each other and are movably connected, the torque of the output end can only be transmitted to the first connecting member or the second connecting member, and the inner tub 131 is stationary.

Specifically, the driving member 150 may be a torque motor. The transmission assembly 160 may be a belt transmission assembly, a gear transmission assembly, a rack and pinion transmission assembly, a worm gear transmission assembly, and the like.
In some embodiments, the washing machine body 100 further includes a base 140 fixedly connected at the bottom of the cabinet 110.
Based on the above embodiments of the present application, the base 140 may better support the washing machine body 100, and the whole washing machine can be placed more stably through the base 140. An adjustment mechanism may be provided on the base 140 as required, and the adjustment structure may adjust the support height of the base 140.
