[0029] The second water outlet pipe 4 is in fluid communication with the water outlet of the water storage tank 2. The second water outlet pipe 4 is provided with a refrigeration component, and the outlet of the second water outlet pipe 4 corresponds to the ice water outlet 1b. The refrigeration component in this embodiment includes a heat exchanger 5. The two inlets of the heat exchanger 5 are respectively connected to the cold air channel 60 and the second water outlet pipe 4. The outlet of the heat exchanger 5 is located upstream of the ice water outlet 1b of the second water outlet pipe 4. The heat exchanger 5 is also connected to a first exhaust pipe, and the outlet of the first exhaust pipe corresponds to the first hot air outlet 1d. In addition, the vortex tube 6 has an air inlet 6a, a cold end outlet 6b and a hot end outlet 6c. The cold end outlet 6b of the vortex tube 6 forms the above-mentioned cold air channel 60. The hot end outlet 6c is connected to a second exhaust pipe, and the outlet of the second exhaust pipe corresponds to the second hot air outlet 1e. Along the fluid flow path, the second water outlet pipe 4 is also provided with a second control valve 74 located downstream of the heat exchanger 5 and a self-priming booster pump 75 located upstream of the heat exchanger 5.

[0030] The air inlet 6a of the vortex tube 6 is also connected to the air inlet pipe 7, on which the first control valve 71 and the air pump 72 are provided; the drinking water equipment also includes a controller and a first temperature sensor 73 for detecting the temperature downstream of the heat exchanger 5 of the second water outlet pipe 4, the controller is electrically connected to the first temperature sensor 73 and the air pump 72, and the controller is configured to control the rotation speed of the air pump 72 accordingly according to the detection result of the first temperature sensor 73.

[0031] In addition, along the fluid flow path, the pipeline 1 is also provided with a heat tank 9 located downstream of the water storage tank 2, and a heating unit 91 is provided in the heat tank 9. The outlet of the pipeline 1 located downstream of the heat tank 9 corresponds to the hot water outlet 1c. In addition, the pipeline 1 is also provided with a fifth control valve 80 adjacent to the hot water outlet 1c and a sixth control valve 78 located upstream of the first pre-filter element 81. The heat tank 9 is also fluidically connected to a drain pipe 10, and a third control valve 77 is provided on the drain pipe 10.

[0032] The first control valve 71, the second control valve 74, the third control valve 77, the fourth control valve 79, the fifth control valve 80 and the sixth control valve 78 are all solenoid valves, and each solenoid valve is electrically connected to the controller for controlling the corresponding solenoid valve to operate through the controller to achieve different water outputs of the drinking water device.

[0033] The working process of the drinking water equipment in this embodiment is as follows:

[0034] 1. Water production mode:

[0035] Detect whether the liquid level in the water tank 2 is at a high water level (a liquid level float may be provided in the water tank 2 to detect the liquid level). If not, open the sixth control valve 78 and the booster pump 76, and the drinking water device starts to produce water; if yes, stop producing water;

[0036] 2. Heater heating mode:

[0037] When the liquid level in the water storage tank 2 is greater than both the low water level and the middle water level, the heating unit 91 in the heat tank 9 is started, and the heating unit 91 is turned off when the second temperature sensor provided in the heat tank 9 detects a preset temperature;

[0038] 3. Heat preservation mode:

[0039] When the temperature detected by the second temperature sensor in the heat bulb 9 is lower than the preset temperature, which is generally 5°C lower than the preset temperature for stopping heating, the controller first detects whether the above heat bulb heating mode is satisfied and then turns on the heating unit 91 until the temperature reaches the preset temperature;

[0040] 4. Overflow mode:

[0041] This mode will be entered when the heating unit 91 in the heat tank 9 fails or the liquid level float in the water tank 2 fails; for example: when the heating unit 91 in the heat tank 9 has heated the water in the heat tank 9 to the preset temperature, but the second temperature sensor set in the heat tank 9 fails, the heating unit 91 continues to heat until the water boils, and then the hot water in the heat tank 9 will flow back into the water tank 2 through the connection between the heat tank 9 and the water tank 2. If the water level in the water tank 2 is relatively high, the water level in the water tank 2 will continue to rise until it reaches the water level of the overflow float. At this time, the controller will turn off the heating unit 91 and stop heating. Another possibility is that the liquid level float in the water tank 2 fails and cannot give a signal to stop water production. The drinking water device continues to produce water. When the clean water level in the water tank 2 reaches the height of the overflow float, the overflow float detects the water level signal and gives a signal to stop water production. The whole machine stops producing water, and the whole machine enters the maintenance state, informing the user that the machine has a fault.

[0042] 5. Ice water mode:

[0043] When the second control valve 74 receives the opening signal, the second control valve 74 opens, and at the same time opens the first control valve 71, the air pump 72, and the self-priming booster pump 75; the first temperature sensor 73 detects the outlet water temperature in real time; when the preset ice water temperature is 18°C, the first temperature sensor 73 will feedback the temperature signal in real time, adjust the speed of the air pump 72 by the temperature change, and indirectly adjust the air flow of the vortex tube 6 by the speed of the air pump 72, so as to control the total amount of heat exchanged gas, so as to effectively control the outlet water temperature. This temperature can be set according to user needs, and in theory, it can be greater than 0°C;

[0044] 6. Normal temperature water mode:

[0045] When the fourth control valve 79 receives the opening signal, because the fourth control valve 79 is directly connected to the water tank 2, as long as the water level of the water tank 2 is higher than the low water level, normal temperature water can be discharged. If the water level of the water tank 2 is lower than the low water level, the control system needs to remind the user by voice that the water level is insufficient and asks the user to wait.

[0046] 7. Hot water mode:

[0047] When the fifth control valve 80 receives the opening signal, because the fifth control valve 80 is directly connected to the heat bulb 9, hot water can be discharged as long as the water level of the water tank 2 is higher than the low water level. If the water level of the water tank 2 is lower than the low water level, the control system needs to voice remind the user that the water level is insufficient and please wait. At the same time, the control also needs to detect whether the temperature measured by the second temperature sensor reaches the system preset temperature. If not, the user is also reminded by voice that the hot water temperature is low and please take water later.
