Description

Water purifier Technical Field The utility model relates to the technical field of water supply, in particular to a water purifier. Background Along with popularization of healthy drinking concepts, the direct drinking water purifying equipment is widely applied in public places with dense personnel, such as markets, campuses, public communities and the like. Among various selectable drinking water types, cool white is a favored healthy drinking water choice due to compliance with the traditional drinking water habit of the masses and strict sterilization treatment. At present, the main stream water purifying equipment on the market mainly depends on the following two modes of 1. A flow proportion adjusting mode is to use a proportional valve or control the duty ratio of a water boiling pump for outputting hot water and a cold water pump for outputting cold purified water to adjust and control the flow proportion of the hot water and the cold purified water so as to ensure that the mixed output cool and white opening temperature meets the set requirement. However, this approach has significant drawbacks, and the proportional valve and associated components and control techniques involved in adjusting the pump duty cycle result in relatively high costs, which undoubtedly increase the economic burden of equipment production and maintenance, limiting the widespread use of such equipment in a wider range of scenarios. 2. The water storage tank is heated in such a way that a water storage tank which is specially used for storing cool and white water is arranged in the direct drinking water purifying equipment, and the water storage tank has a heating function. Firstly, pouring the cooled white water subjected to heat exchange and cooling into a water storage tank, wherein the temperature at the moment is always different from the set temperature, and then, enabling the cooled white water in the water storage tank to reach the set temperature through a heating means. However, the mode is also obviously insufficient, when a user has water taking demands, if the water temperature in the water storage tank does not reach a set value, the user often needs to go through a period of waiting time until the water storage tank finishes a heating process, so that the user experience is greatly influenced, and the convenience and the high efficiency of equipment use are reduced. In summary, the two existing ways for enabling the output of the direct drinking water purifying device to meet the set temperature for cool and white are difficult to neglect in terms of cost control and user experience, and an innovative technical scheme is needed to solve the problem, so as to promote the industry of the direct drinking water purifying device to develop towards a direction which is more economical, more convenient and more consistent with the user requirements.
