Variable-water-volume pure-water waterway system

Abstract

The invention discloses a variable-water-volume pure-water waterway system. The variable-water-volume pure-water waterway system comprises a first water inlet valve, a front filter element, a water pump, a reverse-osmosis filter element, a controller, a first concentrated-water channel and a first pure-water channel. The first water inlet valve, the front filter element, the water pump and the reverse-osmosis filter element are communicated sequentially. The first concentrated-water channel is communicated with a concentrated-water end of the reverse-osmosis filter element, and the first pure-water channel is communicated with a pure-water end of the reverse-osmosis filter element. A fourth water inlet valve and a mass-flow concentrated-water valve are arranged on the first concentrated-water channel sequentially. A fifth water inlet valve and a high-pressure switch are arranged on the first pure-water channel sequentially. The variable-water-volume pure-water waterway system is characterized in that the variable-water-volume pure-water waterway system further comprises a backflow channel, a second concentrated-water channel and a second pure-water channel; the backflow channel is communicated with a water inlet end and a water outlet end of the water pump, the second concentrated-water channel is communicated with the concentrated-water end of the reverse-osmosis filter element, and the second pure-water channel is communicated with the pure-water end of the reverse-osmosis filter element; a second water inlet valve, facing the water inlet end of the water pump from the water outlet end of the water pump, is arranged on the backflow channel; a third water inlet valve and a small-flow concentrated-water valve are arranged on the second concentrated-water channel sequentially; a quick heating module is arranged on the second pure-water channel; all the electric elements are connected with the controller electrically.

Description

technical field [0001] The invention relates to a pure water machine, in particular to a pure water channel system with variable water volume. Background technique [0002] The flow of the water pump, reverse osmosis filter element, concentrated water valve and pure water output of the traditional pure water machine are all corresponding. To obtain fast heat and large flow of ordinary pure water, a set of small flow pure water equipment and another set of pure water equipment are required. A set of high-flow pure water equipment, or a pure water bucket and fast heating module on the large-flow pure water equipment, both solutions require high cost and occupy a large space. In order to overcome the above defects, we have developed an improved pure water waterway system with variable water volume.

Problems solved by technology

[0003] The purpose of the present invention is to provide a pure water waterway system with variable water volume, which can effectively solve the problem of traditional pure water machines whose water pumps, reverse osmosis filter elements, concentrated water valves and pure water output flow are all corresponding. Fast heating and large flow ordinary pure water requires a set of small flow pure water equipment and another set of large flow pure water equipment, or a pure water bucket and a fast heating module are installed on the large flow pure water equipment, which requires high cost and relatively large occupation. big location problem
