[0002] A wall-mounted drinking water machine is a household device for drinking water, and its characteristics mainly include small size, energy saving, health, durability, intelligence, etc.

[0003] Through the combination of water purification technology and refrigeration technology, the wall-mounted drinking water machine realizes efficient filtration, cooling, and filtered drinking water supply. The water purification technology mainly includes RO (reverse osmosis) technology, UF (ultrafiltration) technology, and activated carbon filtration technology, while the refrigeration technology includes electronic refrigeration, compression refrigeration, and semiconductor refrigeration, etc. When the machine is working for drinking water, it first filters and purifies the water through the water purification technology, and then hands the purified water to the refrigeration system for refrigeration, cold storage, and filtration, and then supplies it to the water outlet faucet for the user.

[0004] Currently, there is only one hot water tank in the wall-mounted drinking water machine, resulting in users being unable to drink cooled boiled water after high-temperature disinfection. At the same time, the remaining water will be repeatedly heated in the hot water tank, leading to mineral deposition and increased hardness, and also resulting in a decrease in minerals, which is not conducive to human health.
