Description

Technical Field

[0001] The utility model relates to the field of pipeline water dispensers, in particular to a pipeline water dispenser with refrigeration function. Background Art

[0002] Pipeline water dispensers are generally used in homes, offices, schools, etc., and are used in conjunction with water purification equipment. They have a built-in PE water tank for water storage. Clean water is placed in the PE water tank in advance, and then heated by a heating tank to make hot water for drinking. Pipeline water dispensers on the market are mainly divided into mechanical water outlets and solenoid valve-controlled water outlets. Mechanical water outlet refers to water outlet control through a mechanical button. Pressing the button will cause water to flow, and stopping the button will stop the water flow. Mechanical water outlet is easy to use, but a complex mechanical structure needs to be set near the water outlet, making the pipeline water dispenser larger in size and not suitable for desktop or wall-mounted pipeline water dispensers. Solenoid valve control controls the water outlet by controlling the on and off of the solenoid valve, and the solenoid valve can be set inside the pipeline water dispenser, making the structure more centralized and flat, making it easier to place on a desktop or hang on a wall. However, the existing hot and cold pipeline water dispensers usually have hot and cold water outlets, so multiple solenoid valves need to be set to control the cold water pipeline and the hot water pipeline respectively, which is costly and occupies a large space. In addition, the direct cooling effect of the existing pipeline water dispensers is not ideal. Therefore, the utility model proposes a pipeline water dispenser with refrigeration.
