Abstract

According to the present invention, when the water level of the purified water reaches the proper level for the purified water collected into the water tank of the water purifier, the oxygen is periodically supplied to increase the oxygen dissolved amount of the purified water and at the same time suppress the contamination to maintain the freshness of the water. As a technical description of the oxygen supply device and method of the water purifier, it is an oxygen supply means that is adopted to purify oxygen under certain conditions for the whole water stored in the water tank in the water purifier which is purified water and sterilization system is adopted. In addition, the water level sensor detects the set water level in the water tank during the process of supplying purified water into the water tank, and when the water level is reached, the oxygen supply means is set to the operation time (t) and the operation stop time ( It is characterized by a method of periodically supplying oxygen while controlling to t1).

The present invention relates to an oxygen supply apparatus and method for a water purifier capable of providing oxygen into a water tank of a water purifier, and more particularly, to supply oxygen to purified water stored in a water tank to increase oxygen dissolved amount and to prevent water deterioration. The present invention relates to an oxygen supply device and method for a water purifier that can supply hygienic and fresh water to consumers.

In general, with the development of the industrial society, natural environmental pollution such as water quality and soil pollution is more aggravated, and the raw water (tap water) is ingested and purified.In recent years, water purifiers are used to purify tap water in each household and use clean water as drinking water. It is a widespread trend.

The type of water purifier is a type that purifies by purifying foreign substances or various contaminants remaining in the tap water. The reverse osmosis water purification system is adopted and water purification takes place through sterilization by UV sterilization lamp. In this regard, a form in which heating is performed by heating means to take water in a state converted into hot water or cold water by cooling by a freezing cycle has been introduced.

On the other hand, a lot of research and development for the dissemination of water purifiers, such as a form that allows consumers to increase the convenience of the user or to take a cleaner clean water.

The water purification and sterilization system will be briefly described through the embodiment of the water purifier shown in FIG. 1. (To explain the water purification system, water (eg, tap water) supplied to the water purifier will be described as raw water) As shown in FIG. 1, the raw water supplied from the line 60 is a precipitating filter 11 corresponding to a reverse osmosis water purification and sterilization system 10, a pretreatment carbon filter 12, a membrane filter 13, and a post carbon filter. (14)-The sterilization lamp 15 is purified and sterilized, and the purified and sterilized water is once stored inside the water tank 20, and the water stored in the water tank is again refrigerated cycle (Fig. The water is supplied as cold water or hot water while being guided into a cold water tank (not shown) or a hot water tank (30) with a heater (not shown).

However, in the water purifier of the above-mentioned type, the purified water collected into the water tank 20 is almost circulated and stagnant, so if this condition is prolonged, it may be contaminated and the freshness of the water may be deteriorated. there was.

Therefore, the present invention has been made in order to solve the above problems, the present invention provides oxygen to the purified water by supplying the oxygen periodically when the water level of the purified water reaches the appropriate level for the purified water collected in the water tank of the water purifier It is an object of the present invention to provide an oxygen supply device and method for a water purifier capable of increasing the dissolved amount and at the same time suppressing contamination to maintain water freshness.

A characteristic technique of the present invention for achieving this object, the water purification and sterilization system is adopted to have an oxygen supply means to supply oxygen under constant conditions for the purified water stored in the water tank in the water purifier to supply the purified water In addition, when the water level sensor detects the set water level of the water tank in the process of supplying purified water into the water tank, and the water level is reached, the oxygen supply means is set to an operating time (t) and an operation stop time (t1). It is characterized by a method of periodically supplying oxygen while controlling with).

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary view showing a schematic configuration of a water purifier according to the present invention.

2 is a flowchart according to the present invention.

If the purified water passed through the water purification and sterilization system is supplied into the water tank 20, the purified water of the water tank reaches the proper level in the process of supplying the purified water tank 20, that is, the water level sensor of the water tank When it detects, the oxygen generating means 40 operates by the program input to the microcomputer for operation (operation time t) while supplying oxygen and then stops operation (operation stop time t1) for the input time. On the other hand, while the water level in the water tank is lowered to the proper level by the use of the purified water of the consumer while the oxygen generating means 40 is to stop the operation and perform the process of replenishing the water through the usual process.

Here, the operating time t of the oxygen generating means 40 is preferably about 3 minutes, and the operating stop time t1 is preferably about 12 minutes.

Referring to the process of obtaining the sterilization water by the normal water purification and sterilization system 10 of the water purifier having the oxygen generating means 40 as described above, the raw water supplied from the water pipe line 60 to settle filter 11 ) Firstly remove contaminants from the pre-treatment carbon filter 12 secondly remove chlorine, organic chemicals-membrane filter (13) thirdly remove bacteria, viruses, heavy metals and carcinogens-post carbon filter ( In 14) in the fourth step, the sterilization treatment in the gas, color and odor removal-ultraviolet sterilization lamp 15 is changed to sterilization water to obtain clean water.

This purified water is stored in the water tank 20 and is supplied to the cold water / hot water tank 30 to supply water as needed.

On the other hand, as described for the present invention is characterized in that the method of forcibly supplying oxygen for the water stored in the water tank 20 in the purification and sterilization process.

In other words, when looking at the oxygen supply method for the purified water stored in the water tank 20, when the water level in the water tank 20 reaches the appropriate level and the water level detection sensor detects this, the microcomputer sends a control signal according to the water tank ( 20 is output to the oxygen supply means 40 disposed in.

Accordingly, the oxygen supply means 40 in the water tank 20 executes driving for an operating time t (3 minutes) according to a pre-input signal and stops driving for an operating stop time t1 (about 12 minutes) while the water tank Oxygen is supplied to the purified water stored in (20).

On the other hand, when the purified water level in the water tank drops due to the consumer's use of water in the operation process as described above, the water is replenished by driving the normal purification and sterilization system.

As described above, in the present invention, when the amount of purified water in the water tank reaches the proper level in the water purifier, the oxygen supply means repeatedly supplies the oxygen to the purified water while repeatedly operating and stopping the water, thereby preventing water contamination. Since the water storage condition is hygienic and increases the oxygen dissolved amount, the freshness of the water can be maintained, so that healthy water can be supplied.
