In order to better understand the water supply device of the present application, it will be further explained and illustrated below. As shown in fig. 1 to 4, the water supply device may include: a first water storage unit 1, a functional water generation unit 2 and a first pressurizing device 4. Wherein, functional water generation unit 2 can be through first water route 3 and first water storage unit 1 intercommunication, and first supercharging device 4 sets up on first water route 3, and the import of first supercharging device 4 can be linked together with first water storage unit 1, and the export of first supercharging device 4 can be linked together with functional water generation unit 2. The first pressurizing means 4 is at least for supplying water from the first water storage unit 1 to the functional water generation unit 2. The first water storage unit 1 is used for storing water with certain capacity, and the water can be water with different temperatures, so that when the functional water generation unit 2 needs to be replenished with water, the first pressurizing device 4 can be directly started to replenish the water stored in the first water storage unit 1 to the functional water generation unit 2. For example, the water supply device may include: a refrigerating unit 15, the refrigerating unit 15 is used for refrigerating the water stored in the first water storage unit 1, so that the water can be cooled to a lower temperature, such as a preferred cold water temperature set by a user, to be cold water, which is always stored in the first water storage unit 1. When the functional water generating unit 2 needs to add water, cold water or uncooled water stored in the first water storing unit 1 may be directly input into the functional water generating unit 2 through the first pressurizing means 4. The functional water generation unit 2 is used to generate functional water, which may receive cold water or uncooled water supplied from the first water storage unit 1, thereby generating functional water, which may be stored in the functional water generation unit 2. When the user needs the functional water, the functional water that has been generated in the functional water generation unit 2 can be output at any time to the user. As a practical matter, the functional water may be cold water or normal temperature water.

As a possibility, the refrigerating unit 15 may comprise an evaporator for introducing a low-temperature refrigerant, which is directly or indirectly heat-exchanged with the water in the first water storage unit 1, thereby lowering the temperature of the water in the first water storage unit 1 to the user-set preferred cold water temperature. The refrigeration unit 15 may also include a compressor, a condenser, and an expander connected in sequence, with the evaporator being connected between the inlet of the compressor and the outlet of the expander. The components are connected together and operated by a compressor to form a refrigeration cycle line, which is filled with refrigerant. Further, an evaporator may be provided on the first water storage unit 1 to enable cooling of the water stored in the first water storage unit 1. In particular, the evaporator may be disposed in a space inside the first water storage unit 1 such that water stored in the first water storage unit 1 can directly contact the evaporator for heat exchange, thereby helping to promote heat exchange effects. In other alternative embodiments, the evaporator may be disposed around the outside of the first water storage unit 1, and heat transfer between the evaporator and the first water storage unit 1 may be enabled.

As a possibility, as shown in fig. 1, the water supply device may include: and a water drainage channel 5, wherein the water drainage channel 5 can be communicated with the outlet of the first supercharging device 4. The water supply device may have at least a first state in which the outlet of the first pressurizing device 4 is communicated with the drain water path 5, the outlet of the first pressurizing device 4 is disconnected from the inlet of the functional water generating unit 2, and the first pressurizing device 4 is in an open state. In the second state, the outlet of the first pressurizing device 4 is disconnected from the water discharge path 5, the outlet of the first pressurizing device 4 is communicated with the inlet of the functional water generating unit 2, and the first pressurizing device 4 is in an open state. The drain waterway 5 is for discharging the inputted water to the outside to drain the water supply device.

That is, when the waterway switching unit includes the first valve 16 and the second valve 17, the second valve 17 may be a pilot valve. When the first supercharging device 4 is not operating, there is no water pressure on the drain waterway 5, and when the pilot valve is closed, it may leak due to its characteristic properties. Thus, when the pilot valve is closed, after the first check valve 50 is positioned upstream of the pilot valve, a length of water having a pressure is formed and maintained between the first check valve 50 and the pilot valve, which pressure ensures that no leakage occurs when the pilot valve is closed.

When the first pressurizing device 4 is not operated for a long time, the water stored in the first pressurizing device 4 is stored for a long time, and the quality of the water is reduced, at this time, before the first pressurizing device 4 supplies water to the functional water generating unit 2, the water supplying device can be switched to the first state, and the water stored in the first pressurizing device 4 for a long time is discharged by the water discharging waterway 5. After that, the water supply device is switched to the second state, and the water in the first water storage unit 1 is input to the functional water generation unit 2 through the first pressurizing device 4. Through the process, stored water with reduced quality for a long time can be prevented from entering the functional water generation unit 2, so that the quality of the functional water output by the functional water generation unit is ensured, and the experience of a user when drinking the functional water is improved.

As a possibility, as shown in fig. 2, the water supply device may include: a first filter element 6 and a first connecting waterway 7. The outlet of the first filter member 6 can be in communication with the first water storage unit 1.

The inlet of the first filter member 6 may be adapted to be connected to a water source, and the water supplied to the water supply means is filtered by the first filter member 6 and then supplied to the first water storage unit 1. Thus, the first filter element 6 is located upstream of the first water storage unit 1. The first filter member 6 may be a filter unit capable of filtering water to improve the quality of the water.

In this embodiment, the water supply device may have at least a first state and a second state.

In the second state, the outlet of the first pressurizing device 4 is disconnected from the inlet of the first filter 6, the outlet of the first pressurizing device 4 is communicated with the inlet of the functional water generating unit 2, and the first pressurizing device 4 is in an open state.

In order to achieve the above object, the outlet of the first pressurizing means 4 may be connected to and disconnected from the inlet of the first filter 6 and the functional water generating unit 2, and the water supplying means may include a waterway switching unit. For example, the waterway switching unit includes a three-way valve at the junction of the first waterway 3 and the first connection waterway 7. As another example, as shown in fig. 2, the waterway switching unit includes a first valve 16 and a second valve 17, the first valve 16 is located in a waterway between an outlet of the first pressurizing device 4 and an inlet of the functional water generating unit 2, and the second valve 17 is located in the first connection waterway 7. The first connecting waterway 7 may further be provided with a second check valve 12, and the second check valve 12 enables the outlet of the first supercharging device 4 to be conducted to the inlet direction of the first filtering member 6. Of course, the waterway switching unit may also adopt other structures or devices capable of achieving the same functions, and the waterway switching unit is not limited in any way.

Similarly, before the first pressurizing device 4 supplies water to the functional water generating unit 2, the water supplying device may be switched to the first state, and the stored water stored in the first pressurizing device 4 for a long time is input to the inlet of the first filtering member 6 for filtering by using the first connecting waterway 7, so as to improve the quality of the stored water, and then flows back to the first water storing unit 1. The waste of water can be reduced through the process. After that, the water supply device is switched to the second state, and the water in the first water storage unit 1 is input to the functional water generation unit 2 through the first pressurizing device 4. Through the structure, the quality of water input to the functional water generation unit 2 through the first supercharging device 4 can be improved, the phenomenon that the functional water generation unit is influenced by stored water with reduced quality in the first supercharging device 4 is avoided, the quality of the functional water output by the functional water generation unit 2 is guaranteed, and the user experience is improved when drinking the functional water.
