The seal ring 4 of the adjustment rod 3 is positioned below the overflow port 211 to close the overflow passage 2 from the overflow port 211 to the drain port 231, thereby ensuring the sealing of the saline chamber. As shown in fig. 4 to 6, when the user is in the state of salting, the salting cover 102 is in the open state, the pressure on the top of the adjustment lever 3 is removed, the spring returns to the natural state, and the adjustment lever 3 is bounced. At this time, the sealing ring 4 on the adjusting rod 3 is positioned at the upper part of the overflow port 211, the overflow channel 2 from the overflow port 211 to the water outlet 231 is opened, and at this time, when a user adds salt to the salt water cavity, once the water level is higher than the overflow port 211, water flows out through the overflow channel 2, so that the salt water is prevented from flowing out through the salt adding port 101.
According to the water softening device provided by the invention, the adjusting rod is abutted with the salt adding cover, so that the overflow channel from the overflow port to the water outlet is in an open state when salt is added, and the problem that a metal pipeline in a cabinet is corroded due to the fact that salt water flows out from the salt adding port when salt is added can be effectively avoided. When the salt adding cover closes the salt adding port, the dish washing machine is in a working state, the overflow port reaches the overflow channel of the water outlet, namely, the overflow channel is in a closed state, the sealing performance of the salt water cavity is ensured, and the salt water is prevented from overflowing from the overflow channel to cause resource waste. The overflow port can be opened and closed by linkage between the adjusting rod and the salt adding cover, and the salt adding device is simple in structure, convenient to operate and suitable for popularization and application.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention in any way, and any simple modifications, equivalent variations and modifications made by those skilled in the art without departing from the scope of the present invention will still fall within the scope of the present invention.
