In winter, the present invention relates to a fan having a cooling and heating function that can be used as a substitute for a hot fan.

A general fan is designed to generate wind by rotating a blower fan connected to a motor. The use of the fan is extremely limited in summer, and the wind is generated by accelerating the air maintained at the outside temperature with a fan. It is not cool, and when used for a long time, there was a disadvantage such as hot wind coming out by the heat of the motor.

Due to this problem, various types of fans have been proposed, including a fan having a heat generating device and a fan having a structure to be used at the same time as a fan and a warm fan, and having a fan that provides an air conditioner function to the fan.

However, the fan as described above has a disadvantage in that the function as the air conditioner and the function as the hot air fan cannot be selected according to the season.

The present invention allows the use of the function as a fan and air conditioner fan and the function as a warmer fan can be used without regard to the season, cold air and hot air by using the circulating water heat exchanged by the cooling device and hot wire cold air And it is intended to present a fan having a cooling and heating function of the structure that can prevent the decrease of the indoor humidity during the hot air generation, and can reduce the power consumption during the cold wind generation.

By installing the structure to circulate the heat exchanged circulating water in the tank with a heat radiation pipe, by selectively operating any one of the cooling device or heating wire to present a fan having a cooling and heating function of the structure to generate cold and hot air. .

In addition, the present invention proposes a fan having a cooling and heating function of the arrangement in which the evaporator constituting the cooling device on the rear of the fan motor and the heat radiating fan is installed on the opposite side of the fan shaft.

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

1 shows a basic configuration of the present invention, the present invention is a support (2) is formed on the stand (1), the motor case 3 is installed on the upper support, the motor 4 is installed inside the motor case The motor shaft 4a protrudes forward so that the blower fan 5 is coupled thereto, and the outer periphery of the fan is covered with a fan grill 6 by the cooling device 7 and the hot air device 8. ) Consists of a combined structure.

The cooling device and the hot air device according to the present invention are heat-exchanged by cooling water or heat by circulating water and then supplied by a heat dissipation pipe installed in a structure wrapped around the outer periphery of the fan. It has a structure to be carried on the release.

To this end, a water tank (9) is provided inside the stand, and a condenser (7a) constituting the cooling device (7) and a heating wire (8a) constituting the hot air device (8) are installed therein to cool / warm the tank. Heat exchange pipe 10 is installed in the fan grill surrounding the blower fan 5 to surround the outer periphery of the blower fan, and the inlet / outlet ports 10a and 10b of the heat sinker pipe are held in the support column. The connecting pipe 11 is used to connect to the respective tanks, and one side of the connecting pipe is provided with a circulation pump 12 so as to circulate the heat-exchanged circulating water into the heat dissipation pipe.

The water tank (9) is constructed in a sealed type using a metal or plastic material that withstands heat and has a pressure resistance, and is installed in the stand, and supplemented separately to prevent the circulating water from being lost in the heat exchange process. The water supply container 13 is installed, and an escape valve 14 is installed to automatically release the pressure when the pressure is increased above the allowable pressure.

The replenishment water supply container coupled to the water tank is made of a removable type, and is coupled to the valve opening and closing structure 13a so that water in the replenishment water supply flows into the water tank when combined.

The cooling device is composed of a compressor 7b, a condenser 7a and an evaporator 7c. The condenser is installed in the water tank, and the compressor and the evaporator are installed insulated from the water tank.

In particular, the evaporator 7c is installed at the rear of the motor case and extends the motor shaft to the rear to couple the heat radiating fan 7d onto the extension shaft 4b. By working together, the chiller is configured to run without a separate fan for evaporation.

The warm air device consists of the heating wire 8a installed in the tank.

The heat dissipation pipe 10 is for discharging the cooled or heated circulating water heat-exchanged by a hot wire or a condenser to the blower fan. The heat-dissipating pipe 10 is installed in a form to surround the blower fan by spirally winding the pipe inside the fan grill as shown in FIG. And, the inlet and outlet of the heat dissipation pipe has a structure connected to each tank.

The circulation of water in the heat dissipation pipe is made by a small circulation pump installed on the connection pipe of the inlet and outlet.

In the above configuration, the fan and the cold and hot air are each selected and driven by independent switches, for example, a cold fan / hot fan / fan selection switch, so that the temperature sensor 15 is installed in the water tank so as to be linked thereto. It can be configured to control the temperature by installing the cold air temperature and hot air temperature control switch.

Referring to the specific operating state of the present invention by the above configuration as follows.

① Fan operation

The fan is operated by a motor and a blower fan, and is selected to generate only wind when the outside temperature is appropriate, and operates independently regardless of cold and hot air selection, and allows the fan to be controlled in multiple stages. When configuring the wind strength can also be adjusted regardless of cold and hot air selection.

② Cooling fan operation

When the cold air switch is selected and operated, the cooling device is operated according to the set temperature range, and the circulating water in contact with the condenser is cooled. It is circulated and discharged by carrying cold heat to the blowing fan wind while passing through the heat radiating pipe.

The hot heat is sent to the evaporator when the cooling system is started and the evaporator is released to the rear of the motor case by the action of the heat radiating fan.

When the cooler is in operation, the blower fan also rotates according to the selected wind intensity to generate cool winds such as air conditioners, thereby generating cool winds in hot summer days.

③ Heater operation

When the hot air switch is selected and operated, the heating wire heats the circulating water in the tank according to the set temperature range, and the circulation pump operates to discharge the heated circulating water into the circulation line consisting of the water tank, the heat radiation pipe, and the water tank.

Hot heat is emitted from the heat radiation pipe by the rotation of the blower fan.

When the circulating water is heated for a certain time and the pressure in the tank rises, the escape valve releases the pressure and simultaneously sprays water vapor to compensate for the lack of humidity due to the heating of the indoor air, and the loss of the circulating water is supplied from the refill water supply tank. .

According to each operation described above, the present invention can be freely used as a fan, a cold fan, and a hot air heater, thereby enabling use without regard to seasons.

The present invention can selectively use the function as a fan and an air conditioner and the function as a hot fan, can be used without regard to the season, cold and warm air by using the circulation water heat exchanged by the cooling device and hot air When it occurs, it is possible to prevent the deterioration of indoor humidity, and by driving the heat radiating fan by the driving motor of the blowing fan, the power consumption can be reduced.
