The booster pump 32 boosts the pressure of the raw water so that the raw water entering the dish washer can pass through the RO reverse osmosis membrane of the secondary filter element 33, thereby achieving the purpose of reverse osmosis filtration.

Existing dishwashers are usually equipped with ion exchange resin modules to soften hard water and prevent scale formation, but the ion exchange method is limited by the ion exchange capacity of the resin, requires frequent regeneration with salt, and is a cumbersome process to buy and add salt. By adopting the structure, the water softener can replace a resin type water softener, and a user only needs to replace the primary filter element 31 and the secondary filter element 33, so that the salt adding is more convenient than the original salt adding; moreover, the service life of the water softener is longer than that of a resin type water softener, even if a user does not replace the water softener for a long time, scale cannot be generated in the dish washer, and the reliability is higher; not only can prevent the water path of the dish washer from generating scale, but also can provide the user with the function of purified water.

The pure water filters out calcium ions and magnesium ions, prevents scale from being generated in the dishwasher by the washing water during the washing process, and enables the pure water to be used for high-temperature washing or low-temperature washing. When high-temperature washing is required or hard water in the water tank is insufficient for low-temperature rinsing, pure water flows into the dishwasher body 2 through the pure water line. And the hard water that second grade filter core 33 reverse osmosis filter produced flows into water tank 334, makes hard water temporary storage in water tank 334, when needs carry out the low temperature rinsing, hard water flows out from water tank 334, gets into dishwasher main body 2 through the hard water pipe for the low temperature washing. Because the water evaporation is less under the low temperature condition, the scale is hardly separated out; the low-temperature washing is carried out by using hard water, so that the water can be saved, and the waste of water resources is reduced.

The pure water switch valve 331 is used to connect or disconnect a pure water line so that pure water enters or stops entering the dishwasher main body 2. Hard water on-off valve 333 is used to connect and disconnect hard water lines to allow or stop hard water from entering tank 334. The water tank 334 is used to store hard water, and when the hard water is excessive, the water tank is discharged to the outside through a surplus water line 3341.

Referring to fig. 9, the dishwasher further includes a display panel, a communication device, a heating flow sensor, a heater, a temperature sensor, a tank flow sensor 22, a washing pump 24, a drain pump 26, a booster pump 32, a pure water switch valve 331, a switching valve 332, and a hard water switch valve 333, which are electrically connected to the controller.

The controller is used for controlling the dish washing machine, when a user takes out the purified water through the water taking device 1, the heating flow sensor detects the flow change and reflects the flow change to the controller; then, the controller controls the booster pump 32 to start, so that the water purifying assembly 3 filters out purified water, and the purified water is output to a user by the water taking device 1; meanwhile, the controller controls the hard water switch valve 333 to be opened, and hard water produced by filtering by the water purification assembly 3 enters the water tank 334. When the user needs hot water, the controller controls the heater to heat the water, and then outputs the heated water to the user.

The communication equipment is a WiFi module and is connected with the mobile terminal through WiFi, and a user can control the dish washing machine through the mobile terminal. The display panel is used for displaying the working state of the dishwasher. The controller detects the water temperature of the heater through the temperature sensor and controls the heating power of the heater to enable the purified water to reach the set temperature.

The dishwasher washing program comprises: pre-washing, hot washing, low-temperature rinsing and high-temperature rinsing. Pre-washing and cold rinsing, without heating hot water, hard water in the water tank can be used, if the hard water in the water tank is insufficient, pure water is filtered out by the water purification unit 3 and used as a pre-wash or a cold rinse. Hot washing and hot rinsing, water needs to be heated, and water is fed in a pure water mode. The heater directly heats the pure water to a temperature required for washing. The program may compensate the heating temperature for the ambient temperature. The tank flow sensor 22 is used to detect whether the water entering the dishwasher body 2 satisfies a washing requirement. The pure water switch valve 331 is used to control the water supply to the dishwasher body 2 or to cut off the water supply. The switching valve 332 has two states, in which hard water cannot enter the dishwasher body 2 and pure water can enter the dishwasher body 2 at one state. In a specific practical application, the water tank 334 is placed higher than the drain cup 23, and when the switching valve 332 is in the second state, hard water enters the dishwasher body 2 under the gravity, and pure water cannot enter the dishwasher body 2. The controller may control the switching valve 332 to introduce hard water or hot water as necessary to implement low temperature washing or high temperature washing. In addition, the controller controls the washing pump 24 to be turned on and the drain pump 26 to be turned off, so that the washing water is repeatedly transferred to the washing spray arm 25 for the purpose of washing the dishes. When it is necessary to drain the sewage, the controller controls the drain pump 26 to be turned on to drain the sewage.
