The present invention relates to a water-cooled cold fan that achieves a cooling effect by evaporation of water, and more particularly to a cold / hot air fan that uses high-frequency air to selectively generate cold and warm air at the same time as sterilizing air conditioning by attaching a stop generating high frequency .

In general, an air conditioner for obtaining a cooling effect is roughly classified into an air conditioner using a heat exchanger by evaporation of a refrigerant flowing through an inside of a cooler using a heat exchanger by evaporation of water and a heat exchanger.

As shown in FIG. 1, a water-cooled cold air blower using evaporation of water is a water tank in which a predetermined amount of cooling water is dehydrated below the main body 10 in which an air inlet 11 is formed on a rear surface and an air outlet 12 is formed on a front surface thereof. 20 is provided and comprised.

Inside the main body 10, a pair of rollers are installed to face up and down, the lower roller 31 is installed to be immersed in the fresh water in the water tank, and the upper roller 32 is installed at a predetermined interval therebetween. The pair of rollers are provided with a belt 40, which is composed of a nonwoven fabric through which air can pass by rotating by upper and lower rollers 31 and 32 to evaporate the water soaked. do. A blowing fan 50 is installed at the rear of the belt 40 to help evaporate water. Numeral 51 denotes a fan motor for driving the blowing fan, and numeral 33 denotes a drive motor for driving the pair of rollers. Reference numeral 13 denotes a filter for filtering the discharged cold air.

In the conventional cold air fan configured as described above, the belt 40 is rotated by a pair of rollers by the driving of the driving motor 33, and the blowing fan 50 is rotated by the operation of the fan motor 51. Accordingly, the belt 40 is rotated while the water in the tank is wet. The water of the belt 40 is evaporated by the blowing force of the blower fan 50 to absorb the heat of caution, thereby making the surrounding air cool. Make. The generated cold air passes through the air discharge port 12 to perform predetermined cooling.

However, such a conventional water-cooled cold fan has a problem that bacteria are discharged in the fresh water in the water tank to be adsorbed on the belt and bacteria are discharged together with the cold air during the discharge of the heat-exchanged cold air to harm the user's health. In addition, there was a problem of providing a place for breeding bacteria because it is difficult to exchange the water contained in the tank, there was a problem that can not be used except in summer by performing only the cooling function.

On the other hand, a technique for sterilizing discharged roughened air is disclosed in Japanese Laid-Open Patent Publication No. Hei 2-48720. This is an air conditioner 100 using a separate heat exchanger 110 to perform a refrigeration cycle, as shown in Figure 2, by installing a sterilization lamp 120 on one side of the ultraviolet rays to the air before heat exchange By irradiation, the air is sterilized and discharged.

However, such an air conditioner has a problem in that a separate heat exchanger for evaporating the refrigerant is performed by performing a refrigeration cycle using a refrigerant such as freon gas.

Therefore, the present invention is intended to solve this problem, and the main purpose of the present invention is to generate high frequency air in the air before being discharged into the harmonious space to perform sterilization and to replace the cooling water at the same time, thereby preventing bacterial propagation as much as possible. It is to provide a water-cooled cold and hot air fan using a high frequency.

Another object of the present invention is to provide a water-cooled cold air blower using high frequency that can selectively perform cooling and heating.

It is configured with an output control switch for adjusting the thrust of the generator.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

3 is a water-cooled cold and hot air fan using a high frequency in accordance with the present invention. As shown in the drawing, the water-cooled cold air blower of the present invention is provided with a water tank 20 in which a predetermined amount of cooling water is provided below the main body 10 in which an air inlet 11 is formed on a rear surface and an air outlet 12 is formed on a front surface thereof. It is composed.

Reference numeral 22 denotes an injection port for injecting water into the tank. Inside the main body 10, a pair of rollers are installed to face up and down, the lower roller 31 is installed to be immersed in the fresh water in the water tank, and the upper roller 32 is installed at a predetermined interval therebetween. The pair of rollers are provided with a belt 40, which is composed of a nonwoven fabric through which air can pass by rotating by upper and lower rollers 31 and 32 to evaporate the water soaked. do. A blowing fan 50 is installed at the rear of the belt 40 to help evaporate water. Numeral 51 denotes a fan motor for driving the blower fan and numeral 33 denotes a drive motor for driving the pair of rollers. Reference numeral 13 denotes a filter for filtering the discharged cold air.

On the upper side of the belt 40 is mounted a high frequency generator 60 for generating a high frequency in accordance with the features of the present invention. A magnetron is generally used as the high frequency generator 60, but it is preferable that the high frequency generator 60 is installed to generate a high frequency downwardly. In addition, a waveguide 61 opened forward and backward is installed below the high frequency generator 60 to guide the high frequency oscillated from the high frequency generator 60 to flow into the front and rear of the belt 40.

On the other hand, as shown in FIG. 4, the output control switch 62 is electrically connected to the high frequency generator 60. The output control switch 62 has three selection modes of sterilization, cold air, and warm air, so that high power and low power are selectively oscillated from the high-frequency generator according to the adjustment of the output control switch to perform sterilization, cold air, and warm air. 63 is a time adjustment switch.

In addition, as shown in Figure 5, the bottom plate of the water tank 20 is formed with a drain port 21, the drain port 21 is provided with a valve 70 for opening and closing it, the upper end of the valve 70 is a water tank ( 20 is located inside and the lower end is located outside the water tank to open and close the drain 21. At this time, the bottom plate of the tank is preferably configured to be inclined downward toward the drain port so that the drainage is made easier. A spring 71 is installed between the bottom plate of the water tank 20 and the lower end of the valve 70 to elastically support the valve 70 downward. Therefore, in order to replace the cooling water contained in the water tank 20, the valve 70 is raised to allow the valve 70 to automatically block the drain port 21 by the elastic restoring force of the drain surface spring 71.

Hereinafter will be described the operation of the embodiment of the present invention configured as described above.

First, when the cooling air is to be generated to perform the cooling function, the output control switch 62 is adjusted to the cold air position, and when the time control switch 63 is adjusted, the fan motor 51 and the driving motor 33 operate simultaneously. Done.

The belt 40 is rotated by operating the upper and lower rollers 32 and 31 according to the operation of the driving motor 33. The belt 40 rotates while the coolant in the water tank 20 is wet. At this time, the blowing fan 50 rotates to inhale and discharge the air. Since the sucked air is discharged through the belt 40, the cooling water soaked in the belt 40 evaporates and thus absorbs the surrounding heat. The temperature of the sucked air is lowered by about 2 to 3 degrees Celsius to be discharged through the filter 13 and the discharge port 12.

And if you want to perform the sterilization function while ventilating the cold wind, when the high frequency generator 60 is controlled by the low power state using the output control switch 62, the low frequency high frequency wave generated from the high frequency generator 60 is a waveguide ( The bacteria adsorbed on the belt 40 are sterilized by irradiating the front and rear surfaces of the belt 40 through both side paths of the head 61.

On the other hand, if you want to generate the warm air for heating in winter, when the output control switch 62 is adjusted to the warm air, a high frequency of high power is generated from the high frequency generator 60 and irradiated toward the belt 40 through the waveguide 61. As a result, the moisture absorbed by the belt is heated to rapidly increase the ambient temperature. The heating function is performed by discharging the generated warm air to the outside, that is, the harmonious space.

In addition, when water is to be drained or replaced in order to generate natural air instead of cold or warm air, the valve 70 of the drain port 21 installed at the center of the bottom of the water tank 20 is raised as shown in FIG. When joined, the drain port 21 is opened and the water contained in the tank is easily discharged.

As described in detail above, according to the water-cooled cold and hot air fan using the high frequency according to the present invention, sterilization can be performed by low power high frequency and hot air can be generated by high power high frequency, which allows the heating function to be performed in winter. There is this. In addition, it is easy to replace the fresh water in the tank prevents the growth of bacteria and at the same time has the effect of generating a natural wind.
