Description

Oxygen generator assembly and control method of oxygen generator assembly}

The present invention relates to an oxygen generator assembly and a method for controlling the oxygen generator assembly, and more particularly, an input unit for receiving the use of an oxygen generator or a nebulizer, a valve installed between the oxygen generator and the compressor, and from the input unit. An oxygen generator assembly and a method for controlling an oxygen generator assembly including a control unit for receiving a signal to control the valve.

Recently, the necessity of an oxygen generator for supplying fresh air having high oxygen concentration to the room is increasing due to the increase of air pollution such as automobile smoke. Applications of such oxygen generators are expanding include home water purifiers, air conditioners, vehicle oxygen generators, home indoor ventilation oxygen generators, and the like.

On the other hand, small and medium-sized oxygen production methods include a method using an adsorbent (Pressure Swing Adsorption (PSA)) and a gas separation membrane method using a gas diffusion and permeation rate difference.

Here, the PSA method using an adsorbent takes a method of obtaining oxygen by removing nitrogen by using an adsorbent such as zeolite by purifying air purified through a series of air purifiers. The disadvantage is the high price.

On the other hand, the gas separation membrane method uses a selective gas permeation principle for membranes, and when the air comes into contact with the membrane surface, oxygen can be separated by using a rate difference in dissolving and diffusing nitrogen and oxygen. have. This gas separation membrane method is widely used in places where the installation place is narrow or portable because of the relatively simple and compact structure of the device.

An example of an oxygen generator using the gas separation membrane method is well shown in Patent Publication No. 2001-0103091 and Utility Model Registration No. 20-0279934, and the oxygen generator separates oxygen and nitrogen from the air. And an air compressor for compressing or vacuuming the inside of the oxygen separation module so as to force the inflow of air into the oxygen separation module.

Accordingly, when a predetermined compressed or vacuum state is formed inside the oxygen separation module by the operation of the air compressor, the mixed air is forcibly introduced into the oxygen separation module to be separated into nitrogen and oxygen components. Nitrogen in nitrogen is discharged and only oxygen is used separately.

On the other hand, in recent years, according to the needs of consumers, which are gradually diversified, various additional devices that are beneficial to a person's physical health have been applied to the oxygen generator.

When the user presses the oxygen + nebulizer button of the input unit, the compressor 300 and the oxygen generator 100 operate to discharge oxygen through the oxygen discharge unit 101, and the valve 200 is opened by the controller. Oxygen and outside air are simultaneously introduced into the inlet 301 of the compressor 300 by the suction force of the compressor 300. The introduced oxygen and the outside air are discharged through the discharge port 302 of the compressor 300 and then transferred to the vent pipe 431 of the nebulizer 400 through the connection hose, and then hit the inductor 425 and the space 435. The solution in the space portion 435 is supplied to the solution in the form of fine particles, is transported between the support frame 424 is discharged to the discharge port 426 is transferred to the horizontal tube portion 412 of the nozzle unit 410. Subsequently, oxygen is contained, and the solution in particulate form is supplied to the mask 600 through the connector 500.

When the user presses the oxygen button of the input unit, the compressor 300 and the oxygen generator 100 operate to discharge oxygen through the oxygen discharge unit 101, and the valve 200 is closed by the control unit so that only oxygen is compressed. The suction force of the 300 is simultaneously introduced into the inlet 301 of the compressor 300. As such, when the user uses only oxygen, the nebulizer 400 may be removed and the discharge port 302 of the compressor 300 may be directly connected to the mask 600.

When the user presses the nebulizer button of the input unit, the compressor 300 is operated and the valve 200 is opened by the control unit so that outside air flows into the inlet 301 of the compressor 300 by the suction force of the compressor 300. do. The subsequent procedure works the same as when the user presses the oxygen + nebulizer button.

As such, when the nebulizer 400 is used, the valve 200 is opened by the controller so that the outside air flows into the inlet 301 of the compressor 300 by the suction force of the compressor 300, and the solution is injected at a sufficient injection pressure. There is this. In addition, since the nebulizer 400 and the oxygen generator 100 may be simultaneously used through one compressor 300, the device cost is reduced and the device is compact.

Hereinafter, the oxygen generator assembly control method of the present embodiment having the above-described configuration will be described.

The oxygen generator assembly control method includes an input step of receiving input of using the oxygen generator 100 or the nebulizer 400, and a compressor 300 connected to the oxygen generator 100 when receiving the use of the oxygen generator 100. To prevent the outside air from flowing into the compressor 300, the oxygen outlet is discharged to the discharge port 302, and when the use of the nebulizer 400 is input, the nebulizer 400 enters the outside air into the compressor 300. And an outside air control step of allowing outside air to be discharged to the discharge port 302 connected to the compressor 300.

The input step receives whether the oxygen generator 100 or the nebulizer 400 is used through the input unit such as the oxygen button, the nebulizer button, or the oxygen + nebulizer button.

The outside air control step is connected to the oxygen generating unit 100 by closing the valve 200 when the control unit receives a signal from the input unit, and receives the use of the oxygen generating unit 100 as the oxygen button is pressed by the user The outside air is prevented from flowing into the inlet 301 of the compressor 300 to allow oxygen to be discharged to the discharge port 302 of the compressor 300. In addition, when the user receives input of the nebulizer 400 such that the nebulizer button or the oxygen + nebulizer button is pressed by the user, the valve 200 is opened and the outside air is introduced into the inlet 301 of the compressor 300 to enable the nebble. The outside air is discharged to the discharge port 302 of the compressor 300 to which the riser 400 is connected.
