[0023] An embodiment of the present application provides a drinking water device, which is used to process water so as to provide users with various types of water on demand for convenient drinking. The drinking water device is suitable for various places with drinking water needs. Preferably, the drinking water device of the present application is a water dispenser for household use. Of course, in other embodiments, the drinking water device can also be other devices that can produce water.

[0024] refer to Figure 1 As shown, the drinking water device includes a housing 10 and a multifunctional water system 20. The housing 10 is used as the outer shell of the entire drinking water device to protect the internal water system 20 and other components; the housing 10 is provided with a water inlet 11 and a water outlet 12, the water inlet 11 is used to connect to an external water source (the external water source can be a faucet, a water dispenser, an external water tank 30 or other equipment that can supply water, and the external water tank 30 will be introduced below), the external water source enters the drinking water device through the water inlet 11, and the water outlet 12 can be connected to the external space under control, so that the user can take water at the water outlet 12. The multifunctional water system 20 integrates the normal temperature water function, the cold water function, the hot water function, and the bubble water function into one, thereby providing users with four types of water: normal temperature water, cold water, hot water, and bubble water. The functions are diversified, meeting people's needs for different types of drinking water, and realizing the function of a drinking water device to produce multiple types of water, which greatly satisfies the user experience.

[0025] The multifunctional waterway system 20 includes a first waterway 40, a second waterway 50 and a third waterway 60. Of course, in other embodiments, the multifunctional waterway system 20 may also include only the first waterway 40 and the second waterway 50. The first waterway 40, the second waterway 50 and the third waterway 60 are all arranged in the housing 10 and connected between the water inlet 11 and the water outlet 12. Specifically, after the external water source enters the housing 10 from the water inlet 11, it flows through the first waterway 40, the second waterway 50 and the third waterway 60, and can be discharged from the water outlet 12 after the components in the waterway are processed.

[0026] The first water channel 40 includes a first branch water channel 70 and a second branch water channel 80, and the first branch water channel 70 and the second branch water channel 80 are connected in parallel with each other; the first water channel 40, the second water channel 50, and the third water channel 60 are all connected between the water inlet 11 and the water outlet 12, the first water channel 40 and the second water channel 50 are connected in parallel with each other, and the third water channel 60 and the second water channel 50 are connected in parallel with each other; the first branch water channel 70 is used to provide bubble water to the water outlet 12, the second branch water channel 80 is used to provide water of a first preset temperature to the water outlet 12, the second water channel 50 is used to provide water of a second preset temperature to the water outlet 12, and the third water channel 60 is used to provide water of a third preset temperature to the water outlet 12, wherein the first preset temperature is lower than the second preset temperature, and the third preset temperature is higher than the first preset temperature and lower than the second preset temperature.

[0027] Exemplarily, the first preset temperature can be 10°, that is, the second water channel 80 can provide cold water to the water outlet 12, the second preset temperature can be 90°, that is, the second water channel 50 can provide hot water to the water outlet 12, and the third preset temperature can be 20°, that is, the third water channel 60 can provide normal temperature water to the water outlet 12. It can be understood that the cold, hot, and normal temperatures corresponding to the first preset temperature, the second preset temperature, and the third preset temperature are relative. For example, water at 10° is cold water relative to water at 20°, and water at 20° is normal temperature water relative to water at 90°. Of course, the temperature value is not fixed. The first preset temperature, the second preset temperature, and the third preset temperature can be adjusted according to actual needs, as long as the temperature can meet the aforementioned size relationship. Through the setting of the first water channel 40, the second water channel 50, and the third water channel 60, the drinking water equipment can realize the water outlet function of multiple types and multiple temperature sections.

[0028] The first water circuit 40 is provided with a water tank 41 and a refrigeration assembly 42. The refrigeration end of the refrigeration assembly 42 is provided in the water tank 41. The refrigeration assembly 42 is used to refrigerate the water in the water tank 41. The first branch water circuit 70 and the second branch water circuit 80 are both connected to the water tank 41. Specifically, the water tank 41 includes a first outlet 411. The first branch water circuit 70 and the second branch water circuit 80 are both connected to the water tank 41 through the first outlet 411. Thus, the cold water in the water tank 41 after being refrigerated by the refrigeration assembly 42 can flow to the first branch water circuit 70 and the second branch water circuit 80 through the first outlet 411, respectively.

[0029] The first water branch channel 70 is provided with a gas injection assembly 71 , which is used to inject gas into the cold water in the first water branch channel 70 , so that the first water branch channel 70 can provide bubble water to the water outlet 12 .

[0030] Normally, both normal temperature water and cold water can be pressurized and mixed with gas to form bubble water, that is, the first water channel 70 can be either normal temperature water or cold water. However, bubble water prepared with cold water tastes better than bubble water prepared with normal temperature water because the solubility of gas is greater under cold water conditions, so the degree of gas release after the bubble water is released from the water outlet 12 will be smaller, while the gas will be released faster under normal temperature water conditions. Therefore, the present application connects the first water channel 70 to the water storage tank 41, so that the water on the first water channel 70 for mixing with gas is cold water that has been cooled by the refrigeration component 42, which can improve the taste of the bubble water.

[0031] The refrigeration assembly 42 includes a compressor 421, an evaporator 422, a capillary tube 423, a filter dryer 424, and a condenser 425. The evaporator 422 is arranged inside the water storage tank 41, and the compressor 421, the capillary tube 423, the filter dryer 424, and the condenser 425 are arranged outside the water storage tank 41. Further, the compressor 421 is connected to the evaporator 422, the evaporator 422 is connected to the capillary tube 423, the capillary tube 423 is connected to the filter dryer 424, the filter dryer 424 is connected to the condenser 425, and the condenser 425 is connected to the compressor 421. Specifically, the evaporator 422, as the refrigeration end of the refrigeration assembly 42, can absorb the surrounding heat, so that the refrigerant and the water in the water storage tank 41 are heat-exchanged, thereby achieving the effect of cooling water in the water storage tank 41.

[0032] Furthermore, a first detection member is provided in the water tank 41, and the first detection member is used to detect the temperature of the water in the water tank 41 to assist the refrigeration component 42 in refrigerating the water. In the embodiment disclosed in the present application, the first detection member can be a temperature sensing element such as a temperature sensor. Exemplarily, when the first detection member detects that the temperature of the water in the water tank 41 is higher than the first preset temperature, the refrigeration component 42 can be controlled by the control system to refrigerate the water until the water in the water tank 41 reaches the first preset temperature, and the refrigeration component 42 can stop refrigeration.

[0033] In other embodiments, a UV lamp and a float are further provided in the water tank 41. The UV lamp is used to sterilize and disinfect the water in the water tank 41, and the float is used to detect the liquid level of the water.

[0034] Furthermore, the water system 20 further includes a circulation loop 91, both ends of which are connected to the water tank 41, and the circulation loop 91 is used to circulate the water in the water tank 41.

Under the action of the first pump body 911, the water in the water tank 41 can circulate on the circulation loop 91 through the first inlet 412 and the second outlet 413, so that the water can be in a flowing state, thereby preventing the water from freezing in the water tank 41. In the embodiment disclosed in the present application, the first pump body 911 can be a circulation pump.

[0035] The first water channel 40 is also provided with a first solenoid valve 43. The water storage tank 41 further includes a second inlet 414. The first solenoid valve 43 is connected between the water inlet 11 and the second inlet 414. The first solenoid valve 43 is used to control the on and off of water in the first water channel 40.

[0036] A mixing tank 72 is provided on the first water channel 70. The mixing tank 72 includes a first inlet end 721, a second inlet end 722 and an outlet end 723. The first inlet end 721 is connected to the first outlet 411 of the water storage tank 41, and the gas injection component 71 is connected to the second inlet end 722. The gas injection component 71 is used to inject gas into the mixing tank 72 so that the liquid water on the first water channel 70 forms bubble water. The outlet end 723 is connected to the water outlet 12. A liquid level probe is provided in the mixing tank 72, and the liquid level probe is used to detect the liquid level height of the water in the mixing tank 72.

In the embodiment disclosed in the present application, the second pump body 73 can be a self-priming pump.

[0038] The gas injection assembly 71 includes a gas injection component 711 , a first valve component 712 , a second valve component 713 and a second detection component 714 . The gas injection component 711 is used to provide carbon dioxide gas to the mixing tank 72; the first valve component 712 is connected between the gas injection component 711 and the second valve component 713, and the first valve component 712 is used to adjust the pressure of the carbon dioxide gas, so as to avoid safety hazards caused by excessive gas pressure; the second valve component 713 is connected to the second inlet end 722 of the mixing tank 72, and the second valve component 713 is used to prevent the carbon dioxide gas from flowing back to the gas injection component 711; the second detection component 714 is arranged between the first valve component 712 and the second valve component 713, and the second detection component 714 is used to prompt the outside of the gas volume in the gas injection component 711.
