Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a water path system for draining residual water and an up-taking water dispenser. Background Art

[0002] At present, the design of the up-taking water dispenser on the market is relatively simple, which consists of a main body, a kettle and a water-taking cover. The main body includes a water outlet and a water pump. The kettle has an open water storage cavity for users to directly add water. When in use, the user needs to cover the water-taking cover to close the water storage cavity. A water supply pipeline communicating with the water outlet and the water storage cavity is arranged inside the water-taking cover. After the water pump is started, water is delivered to the water outlet through this pipeline for the user to use.

[0003] However, such a water dispenser has potential safety hazards. When the water pump stops working, there may be residual water in the water supply pipeline. If the user removes the water-taking cover at this time, the residual water may flow out, posing a risk of scalding to the user. To enhance the use safety, a new water outlet system for the up-taking water dispenser needs to be developed to enable it to have a residual water reflux function, ensuring that the water in the water supply pipeline can flow back to the water storage cavity when it stops working, thus avoiding the risk of scalding. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the problem that the residual water of the existing up-taking water dispenser cannot be discharged, and provide a water path system for draining residual water and an up-taking water dispenser. By setting a water pumping device with a two-way driving function, not only can the water in the water storage cavity be guided to flow towards the water outlet, but also the residual water in the pipeline can be guided to flow back to the water storage cavity, avoiding the accumulation of residual water in the water supply pipeline and the leakage of residual water when the water-taking cover is opened.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: A water path system for draining residual water includes a kettle, a water inlet assembly, a water outlet assembly and a water pumping device.

The water outlet assembly includes a water outlet and a water outlet pipe section connecting the water pumping device and the water outlet. The water pumping device can be controllably driven to make the water body flow from the water storage cavity towards the water outlet, or drive the water body to flow from the water outlet towards the water storage cavity.

[0006] The utility model provides a water pumping device with a bidirectional driving function in the water supply pipeline to intervene in the water in the water supply pipeline. When taking water, it guides the water body to flow from the water storage cavity to the water outlet nozzle. After the water taking is completed, it guides the residual water in the water supply pipeline to flow back to the water storage cavity, avoiding the accumulation of residual water in the water supply pipeline. In the actual application scenario, the first water inlet pipe section can be arranged on the water taking cover. When the water taking cover is opened, since the residual water has flowed back to the water storage cavity, there will be no leakage of residual water. Compared with the prior art, the residual water drainage waterway system and the top water intake type water dispenser of the utility model solve the problem of the accumulation of residual water in the water supply pipeline, prevent the leakage of residual water when the water taking cover is opened, and thus avoid the risk of scalding.
