A water purifier rapid heating structure
The invention relates to a quick heating structure of a water purifier. The water purifier comprises multiple parallelly arrayed capillary water pipes arranged between a water inlet tank and a water outlet tank of the water purifier. All the capillary water pipes are located in a same plane to form a heating layer, at the outer circle of the pipe wall of each capillary water pipe, and carbon fiber infrared quartz electrical heating pipes are coiled from the capillary water pipe inlet to the capillary water pipe outlet in a spiraling mode. The inlet water tank and the outlet water tank are all in the structure that one end is big and the other end is small like the shape of a horn. The capillary pipe is a food level silica gel pipe. The inlet water cavity and the outlet water cavity are all food level silica gel cavities which are processed by a one-time forming method. The quick heating structure of the water purifier has the advantages of being fast in heating, short in heating time, and obvious in energy saving. Through the arrangement of a pressure release structure, the water steam impact is reduced, it is guaranteed that no water spray or splash occurs when the water temperature is too high, thus preventing users from being burned, and enhancing the use safety.
