Cold and hot air fan using thermoelectric element {THE MACHINE FUNCTIONING BOTH HEATER AND AIR CONDITIONER}

The present invention relates to a cold and hot air fan using a thermoelectric element, to reduce the noise of the cold and hot air fan by using a pump for moving the cooling water, to install the absorption filter on the back to pass through the incoming air to efficiently lower the temperature of the outside air The present invention relates to a cold / hot air fan using a thermoelectric element that prevents leakage of electronic devices by preventing the coolant from easily leaking from the adiabatic cooling water tank even when the cold / hot air fan is down.

Generally, air conditioners used in summer include air conditioners, ice coolers, and fans.

Among the air conditioners, the air conditioner is divided into an indoor unit for supplying cold air and an outdoor unit for reducing the temperature of the refrigerant, and a compressor, a condenser, an evaporator, etc. must be installed for cooling, and thus there is a problem in that manufacturing and installation are complicated and impossible to move. .

At the same time, the fan was simple in structure and easy to move, but had no cooling capacity. The cold fan was simple in structure, cooling and easy to move, but had to constantly replenish ice.

In order to solve the problems of the conventional air conditioner as described above, Utility Model Registration No. 1989-3821 proposed a cold air blower using a cold air element.

As shown in the drawing, a cold / hot air fan using a conventional cold / hot element is formed by a driving wheel (4) from the front of a cold / hot air blower body (3) having an outlet grill (1) at the front and an inlet grill (2) formed at the rear. In the water tank (5) is equipped with a felt (6) which rotates in the state locked in the lower part and the air circulation fan (7) is mounted to the rear, the exhaust hose (9) to the rear while being connected to the duct (8) to the front ) Is connected to the lower heat sink (10) assembly and the upper heat dissipation plate (10 ') has a configuration that is installed in the center of the water tank (5) in the state of bolted fastening the thermoelectric element (11) having a Peltier effect.

The cold and hot air fan using the conventional cold and hot element configured as described above generates noise when driving the felt that the driving wheel is rotated and the upper part of the water tank is open and is discharged to the outside when the cold or hot air falls or moves. A breakdown occurred due to a short circuit of the surrounding electronics, and there was no insulation effect on the outside of the water tank, which lowered the cooling efficiency due to the outside air and lowered the effect of lowering the temperature of the inlet air because all the incoming air did not pass through the felt. There was this.

The present invention is made in view of the problems of the prior art as described above by using a pump to move the cooling water to reduce the noise of the cold and hot air fan, the absorption filter is installed on the back so that all the incoming air passes through the absorption filter. The purpose of the present invention is to provide a cold and hot air blower using a thermoelectric element to increase the cooling efficiency and prevent the leakage of the electronic device because the coolant is not easily leaked from the adiabatic cooling water tank during the fall or transportation of the cold and hot air blower.

In order to achieve the above object, the present invention provides a body portion having a front grill, a rear grill, and a display portion, an air circulation portion having an air circulation fan circulating air in the body portion, and a temperature of air circulated. In the cold and hot air fan using a thermoelectric element composed of a cooling unit for forming a heat-insulating cooling water tank with a built-in thermoelectric element and a temperature conversion unit for lowering the temperature of the inlet air by using the cooling water of the cooling unit, on the back of the body portion In the rear grille, a cover filter is formed to remove impurities from the inlet air introduced by the rotation of the air circulation fan, and the temperature is changed so that the temperature can be changed by passing the outside air introduced into the rear grill where the cover filter is formed. Form a portion but the temperature conversion portion forms a cooling water distribution pipe at an upper side of the cooling water distribution pipe. A plurality of outlet holes are formed on the lower side to form an absorption filter on the grid-shaped filter body to absorb the cooling water flowing down through the outlet holes, and the water reservoir to collect the remaining cooling water absorbed under the absorption filter. The water reservoir is in communication with the adiabatic cooling tank of the cooling unit, and forms a heat insulating material on the outside of the adiabatic cooling water tank, connects the connecting pipe to the circulation pump on the upper side of the adiabatic cooling water tank, and the cooling water of the temperature conversion part on the upper side of the circulation pump. It provides a hot and cold air fan using a thermoelectric element connected to the pipe and the transfer pipe and formed on the front and front grill of the adiabatic cooling water tank to form a transparent window and check the level of the cooling water.
