Description

In-water discharging apparatus

The present invention relates to an underwater discharge device.

Entering the recent hydroxyl group (OH) as active oxygen _{^{(O -, O 2, O}} 3) and hydrogen peroxide by sterilizing contains a strong base in water, such as (H ₂ O ₂₎ and sterile water as a primary, and thus sterilization Many sterilization methods and sterilizers for disinfecting and supplying purified water to specific spaces or objects have been released. Such disinfectant sterilized water is usefully used in places where sterilization treatment is required, such as food processing, food industry, animal husbandry or hospital.

In recent years, efforts have been made to keep indoor air clean by incorporating underwater discharge technology into household appliances such as air conditioners, air cleaners, and humidifiers to remove bacteria and viruses contained in water.

The method of generating bubbles of active oxygen and ozone through the underwater discharge is based on the bubble mechanism theory, and includes a discharge cell having an electrode in water, and forms an instant strong electric field in the discharge cell. Discharge heat is generated at. Then, bubbles are formed while water is vaporized by the heat of discharge. Such bubbles are easily discharged even by a weak electric field, which leads to rapid destruction of the water dielectric. In this process, radicals, that is, hydroxyl groups, active oxygen and hydrogen peroxide, are generated.

The radicals generated during the underwater discharge process oxidize heavy metals contained in the water, and also sterilize bacteria and viruses contained in the fire and at the same time remove spores of bacteria and viruses.

In addition, when the discharge continues through the discharge cell in the state that the various harmful substances contained in the water is removed, the radicals are accumulated in the water. Eventually, the water itself contains the sterilizing power, and this sterilizing water is used for various sterilization washing operations as sterilizing sterilizing water.

However, the conventional underwater discharge device has the following problems.

* In conventional underwater discharge, fine bubbles must be injected from the outside in order to facilitate discharge in water. That is, fine bubbles are injected from outside to make the surroundings of the discharge electrode into an oxygen atmosphere, and then a high voltage is applied to cause a discharge phenomenon.

In addition, the conventional underwater discharge is oxygen bubbles inside the dielectric tube through electrolysis first by using a needle electrode surrounded by a dielectric tube such as a glass tube inside the tank as a high voltage electrode, and water in the tank as a ground electrode. Generates. Then, when the bubble is filled inside the tube and becomes an oxygen atmosphere, the water discharge takes place. As such, the high voltage electrode having a single needle electrode has a disadvantage in that it is difficult to generate a large amount of fine bubbles by electrolysis without oxygen injection from the outside.

In addition, the conventional underwater discharge method that generates discharge in water using a mechanical high-speed rotary spark gap without generating oxygen bubbles through injection of oxygen or electrolysis is difficult to miniaturize for industrialization and difficult to apply to home appliances. have.

In addition, the conventional underwater discharging technique using electrolysis requires a high voltage electrode and a corresponding electrode (ground electrode) to be separated, and requires a separate electric field strength reinforcing device to use bubbles generated by the high voltage electrode. In addition, a problem of oxidation of the high voltage electrode due to electrolysis occurs, and thus the durability of the electrode is inferior.

On the other hand, conventional humidifiers are mainly used in the ultrasonic method or steam method, and recently, a natural evaporative humidification device using a nonwoven fabric or a paper material has been commercialized.

However, the conventional humidifier using the above method has the following problems.

First, in the case of the ultrasonic humidification method, there is a disadvantage that whitening occurs around the vibrator when used for a long time.

In addition, if the water in the water tank is left without being consumed for a long time, air pollutants enter the water tank and contaminate the water in the storage tank, thereby causing hygiene problems.

In addition, in the case of the steam system, as well as the whitening and hygiene problems, there is a disadvantage that excessive power consumption for steam generation.

In addition, the ultrasonic humidification method or the steam method and the natural evaporative humidifier has a disadvantage that there is only a local humidification effect. That is, the humidifier is not effectively performed on the side away from the space where the humidifier is located, and the indoor humidity is not maintained uniformly.

Particularly, in the case of the ultrasonic humidification method, when the size of the water particles to be sprayed is large, the bottom surface of the humidifier is wetly wet, and there is a risk of mold or slipping on the floor or wall.

In addition, in the case of the conventional humidifier there is no device for sterilizing the water stored in the water tank, there is a disadvantage that a separate sterilization solution must be added in the process of filling the water tank.

In addition, in the case of the conventional natural evaporative humidification apparatus using a non-woven fabric or a paper humidification element, there is a disadvantage that the life of the humidification element is short.

Is an enlarged perspective view showing.

8 to 10, the embodiment is characterized in that the underwater discharge device and the humidifier are provided inside the air conditioner 30 in the form of a module.

In detail, the air conditioner 30 includes a main body 31 forming an outer shape, a front panel 32 provided on the front surface of the main body 31 so as to be rotatable, and an upper portion inside the main body 31. A heat exchanger 31 to be mounted, a drain pan 38 supporting a lower end of the heat exchanger 31, and a fan assembly provided below the heat exchanger 33 to suck indoor air ( 34 and a filter assembly 35 provided in front of the fan assembly 34. The filter assembly 35 may be the same as the filter assembly provided to the humidification device 20.

In addition, an inner cover 36 and a shielding cover 37 are provided between the main body 31 and the front panel 32 to prevent the internal parts from being exposed while the front panel 32 is open. In addition, an inlet 312 through which indoor air is sucked is formed at both lower sides of the main body 31, and an outlet 311 is formed at an upper portion thereof. In addition, a discharge port 311 may be further formed on the upper surface of the front portion of the main body 31.

On the other hand, the inner cover 36 is provided to be rotatable on one side, the water tank 60 for the humidification is mounted on the back of the inner cover 36. In addition, the same humidifying element 62 as the humidifying element provided in the humidifying device 20 is seated on the front surface of the heat exchanger 33. The lower end of the humidifying element 62 is kept submerged in water accumulated in the drain pan 38. In addition, a tube 61 extends at the lower end of the water tank 60, and extends to the bottom surface of the drain pan 38. The discharge cell 10 is mounted on one side of the drain pan 38, and the water level sensor 32 is mounted on the other side. In addition, a solenoid valve (not shown) may be mounted at an inlet of the tube 61 to selectively open and close the valve according to a sensing value detected by the water level sensor 32. That is, when only the condensate flowing down from the surface of the heat exchanger 33 reaches the set level of the drain pan 38, water does not need to be supplied from the water tank 60, otherwise the solenoid valve May be opened to allow water to be supplied from the water tank 60.

In order for this function to be performed, a drain pump for draining the water of the drain pan 38 will need to be mounted on one side of the air conditioner 30. Of course, any method for natural drainage without using a drain pump is applicable.
