Description

Softening device of dish washing machine, control method and dish washing machine

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 dish washer, i.e. the resin absorbs calcium and magnesium ions in water through 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 of the dish washer and exchanges the cations with the calcium and magnesium ions in the resin.

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 cavity and the resin cavity comprises two positions, namely, 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 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 be regenerated, and after the brine with set volume passes, the electromagnetic valve is closed.

And for the two cavities which are 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 saturated saline capacity entering the resin cavity is enough, the electromagnetic valve of the saline cavity and the electromagnetic valve on the water inlet waterway are closed. Pressure is established by upper water injection to force 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 simultaneously, the salt is inconvenient to add into the salt water cavity.

The present invention has been made in view of this situation.

More specifically:

flow direction of softened washing water:

tap water → a solenoid valve 9 → a flow meter 10 → an anti-siphon structure 42 → a resin chamber 3 → a water storage chamber 2 (softened water overflowing from the water storage chamber 2 overflows into the dishwasher through an air hole 43) → a first direction change control valve 7 → the inside of the dishwasher.

Or: running water → solenoid valve 9 → flowmeter 10 → anti-siphon structure 42 → resin chamber 3 → second directional control valve 17 → inside of dishwasher.

Flow direction of regenerated resin water:

the quantity of softened water retained in the water storage chamber 2 opens the first direction change control valve 7 → the brine chamber 6 → the resin chamber 3 → the inside of the dishwasher.

The water in the chamber of the respirator 4 remains during the washing and drying processes, which acts to condense the hot vapor coming out of the respirator 4 and reduces the impact on the environment. The water in the water storage chamber 2 absorbs heat from the surrounding environment through the side walls.
