[0088] By installing a water level detection sensor 11 inside the water storage component 1, the water level height inside the water storage component 1 can be detected. When the water level height inside the water storage component 1 drops to the first water level, the water filling valve 72 is opened and water is added to the water storage component 1 through the water filling pipe 71. When the water level height inside the water storage component 1 reaches the second water level (the second water level is higher than the first water level), the water filling valve 72 is closed, and the water filling is completed.

[0089] The following is combined with Figure 2 The working process of the drinking water equipment of this utility model is described in detail.

[0090] Scenario 1: Cold tank water replenishment mode

[0091] like Figure 3As shown, when the water level in the cold tank 2 is too low or exhausted, the cold water inlet valve 121 is opened, and the water in the water storage component 1 enters the cold tank 2 through the cold water inlet pipe 12. At the same time, the reversing valve 23 switches to the overflow port 21 and connects with the cold water outlet pipe 24. When the water level in the cold tank 2 reaches the preset water level, the water in the cold tank 2 flows into the cold water outlet pipe 24 through the overflow port 21 at the top. When the flow detection component 8 detects that there is water flow in the cold water outlet pipe 24, it transmits a signal to the cold water inlet valve 121, and the cold water inlet valve 121 closes, the water replenishment of the cold tank 2 ends, and at the same time, the reversing valve 23 switches to the outlet port 22 and connects with the cold water outlet pipe 24.

[0092] Scenario 2: Cold water output mode

[0093] like Figure 4 As shown, when the user takes cold water, the cold water inlet valve 121 is closed, and the cold water outlet valve 25 and the hot water outlet valve 34 are opened. The outlet 22 at the bottom of the cold tank 2 is switched to connect with the cold water outlet pipe 24. The water in the cold tank 2 flows into the cold water outlet pipe 24 through the outlet 22, then flows to the hot water outlet pipe 33 and flows out from the outlet component 4 for the user to take cold water. The cold water in the cold tank 2 is replenished after the cold water level is reached (or the water is used up) to avoid mixing of the water in the cold tank 2 with the water added to the cold tank 2 when taking cold water, thereby avoiding affecting the user's experience.

[0094] Scenario 3: Hot water mode

[0095] like Figure 5 As shown, when a user takes hot water, the cold water outlet valve 25 is closed and the hot water outlet valve 34 is opened. The first pump body 35 transports the water in the water storage component 1 to the heating component 31 and heats it. The heated hot water is then transported from the hot water outlet pipe 33 to the outlet component 4 for the user to take hot water.

[0096] Scenario 4: Sterilization Mode

[0097] like ​ As shown, when the water dispenser is in sterilization mode, the cold water inlet valve 121 and the cold water outlet valve 25 are opened, and the hot water outlet valve 34 is closed. The water in the water storage component 1 enters the heating component 31 through the hot water inlet pipe 32. The hot water heated by the heating component 31 then flows back to the cold tank 2 through the cold water outlet pipe 24. The water in the cold tank 2 then enters the water storage component 1 through the cold water inlet pipe 12. Under the action of the first pump body 35, the hot water circulates in the sterilization circuit, thereby sterilizing the water storage component 1, the cold tank 2, and the pipes and valves.

[0098] It should be noted that although the pipeline machine is taken as an example to introduce the water drinking equipment of the utility model, this is not restrictive, the water drinking equipment of the utility model is also applicable to any other possible form, etc., such flexible adjustment and change does not deviate from the principles and scope of the utility model, and should be included in the protection scope of the utility model.

[0099] So far, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Without deviating from the principles of the utility model, those skilled in the art can make equivalent changes or replacements to related technical features, and the technical scheme after these changes or replacements will fall within the protection scope of the utility model.
