Detailed ways

The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

A waterway system 100 in accordance with an embodiment of the present invention is described below with reference to FIG. As shown in FIG. 1, the waterway system 100 can generally include a water tank 10, a first waterway unit 20, a second waterway unit 30, and a hot tank 21.

The water tank 10 has a water inlet and at least two water outlets, wherein the water inlet can be in communication with a municipal natural water pipe. That is, the water tank 10 may include two or more water outlets so that water can be supplied to different waterway units.

In some embodiments, the waterway system 100 can include: a water tank 10 having two water outlets, a first waterway unit 20, and a second waterway unit 30, the first waterway unit 20 being in communication with one of the water outlets, the first waterway unit 20 A hot tank 21 is provided. As shown in FIG. 1, the hot tank 21 is provided with a hot tank water inlet 211, a hot tank water outlet 212, a hot tank drain 213, and a vapor outlet 214. Wherein, the vapor outlet 214 is in a normally open state, so that the steam generated during the hot water production of the hot tank 21 can be discharged through the vapor outlet 214 in time to prevent the pressure in the hot tank 21 from being excessively large. In other words, since the hot tank 21 is in communication with the outside, the water in the water tank 10 can flow into the hot tank 21 for heating by gravity or water pressure in the natural water pipe without additional pressurization.

The second waterway unit 30 is in communication with another water outlet, and the second waterway unit 30 is provided with a pressurizing device 33 and a soda water generating device 32, which causes the water pressure of the second waterway unit 30 to be higher than the first waterway unit 20 water pressure. It can be understood that when the soda water generating device 32 makes the soda water, the soda water generating device 32 has a large amount of carbon dioxide gas, and therefore, the water in the water tank 10 cannot be normally flowed into the soda water by gravity or pressure in the natural water pipe. Within the device 32, only the water in the water tank 10 is delivered to the soda water generating device 32 by the pressurization of the pressurizing device 33. Among them, the pressurizing device 33 may be a booster pump.

Thus, the waterway system 100 according to the embodiment of the present invention has the first waterway unit 20 that produces hot water and the second waterway unit 30 that makes soda water, and the second waterway unit 30 is provided with the pressurizing device 33 in the second waterway unit 30. The water pressure of the unit 30 is higher than the water pressure of the first waterway unit 20, and the waterway system 100 can select different water discharge modes according to the characteristics of the different waterway units to ensure the normal water production of the waterway system 100.

In still other embodiments of the present invention, the waterway system 100 further includes a cold tank 91 and a refrigeration unit. Refrigeration unit is cold The water in the tank 91 is cooled, and the soda water generating device 32 is built in the cold tank 91 as shown in FIG. In this way, the overall structure of the waterway system 100 can be made more compact and smaller, and the cold water in the cold tank 91 can be cooled to the soda water generating device 32, thereby preparing a soda water with better outlet feeling.

In other alternative embodiments, the refrigeration unit includes a compressor 41, a condenser 42 and an evaporator 43 that are sequentially connected, wherein the evaporator 43 is located in the cold tank 91. The evaporator 43 is directly exchanged with the water in the cold tank 91 in comparison with the indirect cooling water from the outside of the cold tank 91, and the cooling speed is faster.

Among them, a replenishing water passage unit 50 is provided between the water tank 10 and the cold tank 91, and the cold water tank 91 is replenished by the replenishing water passage unit 50. A drain port may be provided at the bottom of the cold tank 91. Thus, when the cold tank 91 is not used for a long period of time, the water can be drained through the drain port to prevent bacteria from growing in the cold tank 91.

In some alternative implementations, the second waterway unit 30 can include a main waterway that extends at least partially into the cold tank 91. That is, the water of the main water passage is cooled by the cold tank 91, so that the water of the second water passage unit 30 is cooled.

In an alternative embodiment, the main waterway includes a stainless steel tube section 34 and a stainless steel tube section 34 located within the cold tank 91. Stainless steel has good thermal conductivity, thereby speeding up the cooling of water in the main water passage.

In a further alternative example, the stainless steel tube section 34 is helically coiled within the cold tank 91. Thereby, the contact area of the stainless steel pipe and the cooling water in the cold tank 91 can be increased, thereby improving the heat exchange efficiency, so that the water in the main water path is rapidly cooled.

In other alternative embodiments, after the main waterway is cooled by the cold tank 91, it is divided into two branches, one of which delivers cold water to the soda water generating device 32, and the other branch directly delivers cold water. In other words, the second waterway unit 30 can directly deliver cold water to the outside, or cold water can be sent to the soda water generating device 32 to prepare low temperature soda water.

In still another embodiment of the present invention, as shown in FIG. 1, the waterway system 100 includes: a water tank 10, a first waterway unit 20, a second waterway unit 30, a normal temperature waterway unit 70, a carbon dioxide transport unit 60, a refrigeration unit, and purified water. Unit 80 and cold tank 91,

Specifically, the water purification unit 80 is connected to the municipal natural water pipe and the water tank 10, that is, the natural water is purified by the water purification unit 80 and then enters the water tank 10. The first waterway unit 20, the second waterway unit 30, and the normal temperature waterway unit 70 are respectively connected to the water outlet of the water tank 10, wherein the first waterway unit 20 is provided with a hot tank 21 to prepare hot water.

The refrigeration unit includes a compressor 41, a condenser 42, and an evaporator 43 that are sequentially connected, and the evaporator 43 is located in the cold tank 91. That is, the water in the cold tank 91 is directly cooled by the evaporator 43.

The second waterway unit 30 includes a main waterway and two branches connected to the main waterway. Specifically, the main waterway extends at least partially into the cold tank 91. After the main waterway is cooled by the cold tank 91, the main waterway is divided into two branches. Among them, one branch sends cold water to the soda water generating device 32, and the other branch directly transports cold water to the outside. That is to say, one of the branches of the second waterway unit 30 emits cold water, and the other branch leaves the soda.

The carbon dioxide delivery unit 60 communicates with the soda water generating device 32 to deliver carbon dioxide to the soda water generating device 32. The carbon dioxide delivery unit 60 may include a carbon dioxide gas cylinder that supplies carbon dioxide gas to the soda water generating device 32 through the carbon dioxide gas cylinder. Of course, the carbon dioxide delivery unit 60 may also include an external carbon dioxide canister that delivers gas to the soda water generating device 32 through the carbon dioxide canister.

The outlets of the normal temperature water passage unit 70, the first waterway unit 20, and the second waterway unit 30 are all in communication with the outlet pipe 92. In other words, the normal temperature waterway unit 70, the first waterway unit 20, and the second waterway unit 30 are discharged outward only through one of the outlet pipes 92, thereby further simplifying the structure of the waterway system 100.
