[0027] In this embodiment, by optimizing the specific configuration of the water system, the water system can directly provide users with (hot) tap water, (hot) filtered water, (hot) pure water or boiled water, thereby increasing the functionality of the kitchen integrated water system and avoiding the need for the traditional kitchen water system to be additionally configured with an independent water purification heating system and drinking water heating system to provide users with hot tap water (filtered water / pure water) or boiled water. This simplifies the structure of the kitchen integrated water system and reduces the occupied space. At the same time, it avoids the compatibility issues caused by the water volume requirements of different water systems and greatly reduces the production cost.

[0028] Specifically, the water system is configured as a composite component including at least a tap water pipe 100, a clean water pipe 200, a first filter element 10, a second filter element 20, a pure water pipe 300, a hot water pipe 400, a first heating element 30 and a second heating element 40. The tap water pipe 100 can be a metal pipe, which is connected between an external water source and a first inlet of the first filter element 10, and is used to introduce external tap water into the first filter element 10 for filtration. The first filter element 10 can be a PCB composite filter element, which at least includes a PP cotton filter element and a post-activated carbon filter element; wherein the PP filter element is also called a melt-blown filter element, which is a filter material made of non-toxic and odorless polypropylene as a raw material, and is heated, melted, sprayed, pulled, and received. The PP filter element has a uniform pore size, a deep filtration structure with a sparse outside and a dense inside, and has high filtration efficiency and excellent acid and alkali resistance. It can effectively remove impurities such as suspended matter, particles, and rust in the liquid; the post-activated carbon filter element can deeply purify water, thoroughly absorb the discoloration and odor in the clean water, and adjust the taste of the clean water. The rinse water pipeline 200 can be a metal hose, which is connected between the first outlet of the first filter element 10 and the rinse water faucet, and is used to lead the filtered water roughly filtered by the first filter element 10 out of the water system. The second filter element 20 can be an RO filter element, which is a reverse osmosis membrane filter element. The pore size of its permeable membrane is as small as nanometers, and can filter impurities such as inorganic salts, heavy metal ions, organic matter, colloids, bacteria and viruses in the water. The pure water pipeline 300 can be a metal hose, which is connected to the second outlet of the first filter element 10, and is used to lead the pure water filtered by the first filter element 10→the second filter element 20→the first filter element 10 out of the water system.

After the heat exchange, the temperature of the pure water increases and flows out from the first outlet of the heat exchanger 90, and then enters the first heating element 30 for heating. The heated pure water is divided into two paths: one path enters the second inlet of the heat exchanger 90 from the first heat exchange pipe 920 and exchanges heat with the low-temperature pure water. At this time, the temperature drops and the pure water is drawn out from the second outlet of the heat exchanger 90, and is drawn out from the second heat exchange pipe 930 and the hot water faucet to obtain boiled water; the other path is drawn out from the hot water pipe 400 and the hot water faucet to obtain drinking hot water.

When the user needs boiled water, the sixth valve body 66 opens and the seventh valve body 67 closes. At this time, the pure water drawn from the second outlet of the first filter element 10 flows through the hot water pipe 400 → the second pump body 80 → the hot water pipe 400 → the first inlet of the heat exchanger 90 → the first outlet of the heat exchanger 90 → the second heating element 40 → the first heat exchange pipe 920 → the second inlet of the heat exchanger 90 → the second outlet of the heat exchanger 90 → the second heat exchange pipe 930 → the sixth valve body 66 → the hot water pipe 400, and finally flows out of the hot water pipe 400. The hot water is drawn out from the hot water tap of the water pipe 400 to obtain boiled water; when the user needs to drink hot water, the sixth valve body 66 is closed and the seventh valve body 67 is opened. At this time, the pure water drawn out from the second outlet of the first filter element 10 flows through the hot water pipe 400 → the second pump body 80 → the hot water pipe 400 → the first inlet of the heat exchanger 90 → the first outlet of the heat exchanger 90 → the second heating element 40 → the seventh valve body 67 → the hot water pipe 400, and is finally drawn out from the hot water tap of the hot water pipe 400 to obtain hot drinking water.
