Preferably, a limiting portion 107 is provided at an end of the mounting hole 104 away from the driver 31, and the limiting portion 107 abuts against the sealing member 5, so that the mounting depth of the transmission shaft 32 can be limited by adding the limiting portion 107, and the sealing effect at the matching position of the matching section 32b and the mounting hole 104 can be further improved by designing the sealing member 5 to abut against the limiting portion 107.
As shown in fig. 8, in the present embodiment, the detecting unit 6 for detecting the position of the cam 321 is further included, and the detecting unit 6 is preferably a micro switch, which is disposed on the outer side wall of the valve body 1 and is close to the transmission shaft 32, and the micro switch is located below the lateral section 1081, so as to ensure that water leakage does not splash onto the micro switch. The micro-switch is provided with a touch part 601 facing the transmission shaft 32, so that when the driver 31 drives the transmission shaft 32 to rotate, the cam 321 can touch the touch part 601 to conduct the micro-switch, and the main controller of the dish washer can determine the position of the water distribution disc 2 according to the conducting signal and the transmission relation, thereby realizing the accurate control of the water outlet state of the water distribution valve.
Example two
As shown in fig. 9, the present embodiment is different from the first embodiment in the structure of the transmission mechanism. In this embodiment, the transmission mechanism includes a worm 43 and a worm wheel 44, the worm 43 forms the transmission shaft 32, or the worm 43 is fixedly connected to one end of the transmission shaft 32 far away from the driver 31, the worm wheel 44 may be a gear or a bevel gear, which is fixedly arranged on the outer surface of the lower rotating shaft 202 and is matched with the worm 43, and other parts are the same as those of the first embodiment.
What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
