The invention discloses a direct water dispenser based on infrared distance measurement sensors. The direct water dispenser comprises a water receiving bin, a water outlet pipe and an electromagnetic valve, wherein the electromagnetic valve is arranged on the water outlet pipe. The first height h1 of the water receiving bin and the second height h2 from the lower end of the water outlet pipe to the bottom of the water receiving bin are recorded in a data processing module in advance. The data processing module controls the first infrared distance measurement sensor to detect the first distance d1 front the top of the water receiving bin to the top wall of a water receiving container and subject the first distance from the first height to obtain the third height h3 of the water receiving container. The data processing module controls the electromagnetic valve to be switched on; in the process of keeping the electromagnetic valve to be switched on, the data processing module controls the second infrared distance measurement sensor to detect the second distance d2 front the lower end to the inner water level of the water receiving container continuously, and when the result obtained by subjecting d2 from h2 is equal to h3, the data processing module controls the electromagnetic valve to be switched off. The water level in the water receiving container is detected automatically, and the use convenience degree of the water receiving container is improved.
