Description
Technical Field
The invention belongs to the field of dish washing machines, and particularly relates to a softening device of a dish washing machine, a control method and the dish washing machine.
Background
At present, tap water is directly adopted by water used in a dish washing machine, the tap water contains a large amount of calcium and magnesium ions, namely, people commonly say 'hard water', and the calcium and magnesium ions are adsorbed in a water pipe or a containing cavity of the dish washing machine to form precipitates along with the lapse of the service time of the dish washing machine, so that the service performance of the dish washing machine is influenced. Therefore, people install a softening device in the dishwasher, i.e. the resin adsorbs calcium and magnesium ions in water by cations in the resin, and after the resin is used for a period of time, the resin needs to be regenerated, i.e. the resin is taken out from the dishwasher and exchanges the calcium and magnesium ions in the resin with the cations.
Softening installation mainly contains salt water cavity and resin chamber, and the two integration of traditional softening installation are integrative, and install in the dish washer bottom more. The position relation of the saline water cavity and the resin cavity comprises two positions, wherein two cavities are arranged at the left and right positions, and one cavity is arranged at the upper and lower positions (the upper part of the saline water cavity and the lower part of the resin cavity). The two softening devices work in the following modes:
for the softening device at the upper position and the lower position, when regeneration is needed, the electromagnetic valve of the brine cavity is opened, saturated brine automatically flows downwards into the resin cavity under the action of gravity to regenerate, and after the brine with set volume passes, the electromagnetic valve is closed.
And for the two cavities distributed left and right, the working mode between the saline cavity and the resin cavity is as follows: when regeneration is needed, the electromagnetic valve on the salt water cavity is opened, saturated salt water flows into the resin cavity along the set water path, the water inlet electromagnetic valve on the upper portion of the salt water cavity is opened at the moment, water is injected between the water inlet pipelines, and therefore water in the salt cavity is squeezed into the resin cavity. When the volume of the saturated brine entering the resin cavity is enough, the electromagnetic valve of the brine cavity and the electromagnetic valve on the water inlet waterway are closed. Water is injected through the upper part to form pressure to push the saturated brine in the brine chamber into the resin chamber. In order to prevent the incoming tap water from mixing into the salt water cavity to reduce the salt water concentration, the newly-entered water is mostly in the designed water inlet pipeline, and a small amount of water is controlled to enter the salt cavity as much as possible.
However, the softening device with the integrated salt water cavity and resin cavity occupies a large space in the dishwasher and has a limited installation mode, and the addition of salt into the salt water cavity is inconvenient.
