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 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 regenerate, 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 waterway, the water inlet electromagnetic valve on the upper portion of the salt water cavity is opened at the moment, water is injected into the water inlet pipeline, 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.

Preferably, the liquid inlet is positioned at the top of the water storage cavity 2, and the liquid outlet is positioned at the bottom of the water storage cavity 2. Under the scheme, all water in the water storage cavity 2 can flow out of the liquid outlet, so that residue is avoided; the pressure born by the liquid outlet also reaches the maximum, which is favorable for the water flow to enter the brine cavity 6.
In a further scheme, the brine cavity 6 is provided with an inlet and an outlet, the resin cavity 3 is provided with a water inlet and a water outlet, the inlet of the brine cavity 6 is communicated with the liquid outlet of the water storage cavity 2, the outlet of the brine cavity 6 is communicated with the water inlet of the resin cavity 3, and the water outlet of the resin cavity 3 is communicated with the inside of the dish washing machine. Therefore, the brine cavity 6 can receive water with stable pressure and stable speed in the water storage cavity 2, and the brine in the brine cavity 6 enters the resin cavity 3 to complete regeneration.
Further scheme, the liquid outlet of water storage chamber 2 be linked together through first pipeline 14 with the import in salt solution chamber 6, be provided with first control valve 8 on the first pipeline 14, first control valve 8 is opened, switches on first pipeline 14, forms salt solution after the water in the water storage chamber 2 gets into salt solution chamber 6, salt solution gets into resin chamber 3 and carries out resin regeneration.
In this scheme, the liquid outlet of water storage chamber 2 is in the bottommost, and the liquid outlet passes through the import intercommunication in first pipeline 14 and salt water chamber 6. The first control valve 8 is used for controlling the on-off of the first pipeline 14. In a normal state where resin regeneration is not required, the first control valve 8 is closed, and water in the water inlet pipe 5 is stored in the water storage chamber 2 to a predetermined amount after entering the water storage chamber 2. When resin regeneration needs to be carried out, the first control valve 8 is opened, the first pipeline 14 is conducted, water in the water storage cavity 2 enters the saline water cavity 6, the impact caused by the water is small, rated saline water enters the resin cavity 3, the using amount is small, and the regeneration effect is good.

The water inlet pipe 5 is the water inlet pipe, and tap water enters the softening device through the water inlet pipe 5, enters the resin cavity 3 for softening, or enters the water storage cavity 2 for temporary storage, so that the saline water cavity 6 can be used conveniently. In order to control the direction of the incoming water flow, the water inlet pipeline 5 may be specifically configured as the following scheme, but is not limited to the following scheme:
scheme 1, the inlet pipe 5 on be provided with switching-over control valve 7, switching-over control valve 7 includes two at least play water ends, two play water ends be linked together through the inlet of pipeline with water storage chamber 2 and the water inlet of resin chamber 3 respectively.
In this scheme, switching-over control valve 7 can be the three-way valve, and the end of intaking of three-way valve is connected with water intake pipe 5, and the play water end of three-way valve, one is linked together through the inlet of pipeline with water storage chamber 2, and one is linked together through the water inlet of pipeline with resin chamber 3. So, through controlling this three-way valve, alright in order to control the rivers trend, the running water directly gets into resin chamber 3, and inside the running water got into dish washer after softening, perhaps the running water got into temporary storage in water storage chamber 2, when needs carry out resin regeneration, the control valve on the first pipeline 14 was opened, and the rivers steadily get into salt water chamber 6, promote salt water and get into resin chamber 3 in, reduce the quantity of rated salt water.
In this scheme, water intake pipe 5 is the main line with water sources such as water taps intercommunication, and water intake pipe 5 sets up the control valve respectively on two branches through the inlet of two branch road pipelines and water storage chamber 2 and the water inlet intercommunication of resin chamber 3. If softening is required, the control valve on the branch pipeline communicated with the resin cavity 3 is opened, and if regeneration is required, the control valve on the branch pipeline communicated with the water storage cavity 2 is opened.
