Water Purifier and Its Low Temperature Compensation System

Abstract

The invention discloses a water purifier and a low-temperature temperature compensation system thereof. The low-temperature temperature compensation system comprises an automatic control device, as well as a flow detector and a heating pipe mounted on a pipeline in sequence, wherein a water passage is arranged in the heating pipe, a water inlet end of the heating pipe is provided with an inlet water temperature sensor, and a water outlet end of the heating pipe is provided with an outlet water temperature sensor; the automatic control device controls the heating of the heating pipe according to temperature values detected by the inlet water temperature sensor and the outlet water temperature sensor, and a water flow rate detected by the flow detector. The low-temperature temperature compensation system of the water purifier is simple in structure, convenient to control, low in energy consumption, energy-saving and environment-friendly, the water purifier using the temperature compensation system can perform temperature compensation on the temperature of raw water under a low temperature environment, thus the yield of RO film purified water is increased, the optimal work state of an RO film is reached, and the service life of the RO film is prolonged; besides, the outlet purified water temperature is increased to a certain extent, and a user can conveniently drink.

Description

technical field [0001] The invention relates to a low-temperature temperature compensation system, in particular to a low-temperature temperature compensation system for a water purifier. The invention also relates to a water purifier using such a compensation system. Background technique [0002] Water purifiers have now become essential products for household appliances. From traditional water purifiers with water storage tanks to large-flow water purifiers without tanks and commercial water purifiers, the water quality and flow rate of their effluents can meet the requirements of laboratory conditions. Meet certain national standard requirements, but in fact, as far as reverse osmosis water purifier is concerned, reverse osmosis membrane is affected by its various characteristics, and one of the very close influences of its effluent water quality and effluent flow rate is temperature change. The flow of pure water filtered by the reverse osmosis membrane changes in direc...

AI Technical Summary

Problems solved by technology

Part of the reverse osmosis water purifier product solution is to add a constant temperature water tank, place the whole machine in the constant temperature water tank or place a constant temperature water tank at the front end of the reverse osmosis water purifier pipeline to increase the water temperature of the water purifier or prevent the whole machine from freezing in winter , this scheme cannot maximize the flow rate of pure water at low temperature during the operation of the whole machine, because in the low temperature environment, the temperature of the water in the filter element, filter bottle and pipeline of the water purifier is very low, and it takes a long time to heat up. Exchange and heat transfer can increase the temperature to the optimum temperature of the reverse osmosis membrane, so the water production rate of pure water cannot be improved very well

When the whole machine has not been used for a long time, the natural cooling of the water temperature will cause the heating to be repeated repeatedly, resulting in a waste of energy

The heating tube is placed at the front without any water filtration, and the large heating tube space will cause the heating tube to scale and bacteria for a long time, greatly shortening the service life of the product
