Description

{COOLING AND HEATING ELECTRIC FAN}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cold / hot electric fan, and more particularly to a cold / hot fan capable of discharging cold heat and heat generated through a thermoelectric element to the outside using an air circulating fan .

Generally, the air conditioner including the air conditioner, which is in the market, is produced as a separate product of the indoor unit and the outdoor unit. As described above, since the indoor unit and the outdoor unit are separated from each other in the conventional refrigerator or hot air fan, it is difficult to install the indoor unit and the outdoor unit.

In addition, since the refrigerant is circulated to the evaporator by compressing the refrigerant gas in the compressor, noise is generated when the compressor is driven, and the cooling device circulating the refrigerant to recover the heat around the evaporator and cool the refrigerant has a relatively large power consumption. There is a problem that it causes environmental destruction such as global warming due to consumption of refrigerant.

Particularly, since the Freon gas is an extremely harmful substance to the human body, special care is required when handling and disposing it, and there is a problem that the service life is limited and the cost is increased.

Prior Art 1: Open Patent Publication No. 2011-0075761, entitled "Four Direction Cold < RTI ID = 0.0 & Prior Art 2: Registration Practical Utility Model No. 371,260, entitled "Hot air blower using a wing configured with thermoelectric elements"

An object of the present invention is to provide an environment-friendly cold / hot fan which can save costs due to a simple structure, which does not require the use of a compressor, a refrigerant and an outdoor unit so as to solve the conventional problems.

In addition, it is intended to provide a cold / warm fan which can reduce the maintenance cost due to relatively low power consumption, emit cold and heat at the same time, and easily store and move.

A cold / hot air fan according to an embodiment of the present invention includes: a body part having at least one surface thereof opened to send air out; A thermoelectric module disposed inside the body and having at least one thermoelectric element for generating heat and heat; A heating unit mounted on the body and heating the heat generated by the thermoelectric element; And an air blowing unit installed in the body part and circulating the air to maintain the temperature.

In addition, a discharge port for discharging air to the outside is formed on one side of the body, a safety net is provided at the discharge port, and an air filter is installed in the safety net to filter dust and various particles in the air.

In addition, a knob capable of being held by a user is provided at one side of the body portion.

In addition, the thermoelectric elements may be arranged to be joined in the vertical direction, and when the thermoelectric element generates cold heat, cold heat is generated simultaneously in the thermoelectric elements in the up and down direction.

The heating unit may include at least a PTC heater, and the PTC heater heats the heat generated in the thermoelectric device and discharges the heated heat to the outside through the blower unit.

In addition, the air blowing unit is provided with at least an air circulating fan to circulate cold and hot.

In addition, the body includes an on-off button capable of on / off control of the power source, a mode selecting unit capable of selectively controlling the cold generating mode or the heat generating mode, and a controller .

According to the present invention, since a compressor and an outdoor unit are unnecessary and can be formed in a simple structure, the cost can be reduced, and installation or disassembly is easy.

Also, it is highly efficient as compared with air conditioner and hot air, and it is possible to prevent environmental pollution because refrigerant such as freon gas and oil is not used.

In addition, it is excellent in movement and storage, and is excellent in portability.

In addition, since the rotation controlling unit is provided, the temperature can be maintained to a user-desired space.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the spirit of the present invention is not limited to such embodiments, and the spirit of the present invention may be proposed differently by adding, modifying and deleting constituent elements constituting the embodiment, .

FIG. 1 is a perspective view of a hot / cold electric fan according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of a cold / hot electric fan according to an embodiment of the present invention.

1 and 2, a cold / hot electric fan 1 according to an embodiment of the present invention includes a body 10, a thermoelectric module 20, a heating unit 30, a blowing unit 40, . ≪ / RTI >

The body 10 can form the appearance of the cold / warm air fan 1.

The body 10 may be formed in a rectangular parallelepiped shape having a hollow portion formed therein, and at least one surface thereof may be detachably formed.

On one side of the body portion 10, a discharge port 13 through which air can be discharged to the outside can be formed. The delivery port 13 may be formed in a circular shape and may include a safety net 14 covering the delivery port 13. At this time, the safety net 14 may be equipped with an air filter (not shown) for filtering dust and various particles in the air.

A handle 11 that can be held by a user may be provided on one side of the body 10. The handle 11 can be pivotally coupled to the body 10 at a predetermined angle, and can be detachably coupled to the body 10 with a hinge (not shown). The user has an advantage in that the user can grip the grip 11 and move the cold / warm air fan 1 to a desired space, and the mobility can be improved, thereby saving power consumption. At this time, the body part 10 may be formed of a light material such as at least plastic to facilitate movement.

The body part 10 is provided with an on / off button 121 for controlling on / off of the power, a mode selecting part 122 for selectively controlling the cold generating mode or the heat generating mode, A controller 12 including an intensity controller 123 may be provided. In addition, the controller 12 is provided with a rotation control unit 124 for controlling the rotation of the cold / warm air fan 1, so that the user can maintain the temperature to a desired space.

The thermoelectric module 20 is provided inside the body 10 and may include at least one thermoelectric element 21 or 22 that generates heat and heat. The thermoelectric elements 21 and 22 may be arranged to be vertically joined to each other, and may be installed at a lower portion of the air circulation passage to receive power supply.

The thermoelectric elements 21 and 22 may be provided as cold devices 21 and 22 formed of a cryocooler and a thermal device that emit cold heat and heat when power is applied thereto. And cooling fins (not shown) and heat dissipation fins (not shown) for dissipating heat. The cooling / heating elements 21 and 22 are environmentally friendly and can simplify the structure because they can pollute the environment and replace refrigerant such as freon gas which is harmful to the human body.

The heat and cooling elements 21 and 22 may be connected to bridges (not shown) of a metal material having excellent thermal conductivity to radiate cold or hot heat. That is, the cold heat generated when power is supplied to the heat and cooling elements 21 and 22 can be diverted to the atmosphere through the cooling fin. More specifically, when a current is applied to the heat element, the heat element 21 or 22 recovers the heat of the cryocooler and discharges the heat to the atmosphere, thereby lowering the temperature of the cryocooler. In accordance with the heat exchange function of the cryocooler, The air temperature in the vicinity may be lowered.

Dust and various particles can be filtered and sucked by the air filter, and air passing through the cooling fins formed in the heat-generating elements 21 and 22 can be sucked into the inside of the body part 10 by cold air And the air passing through the radiating fins can be converted into hot air and circulated.

For example, when the thermoelectric elements 21 and 22 generate cold heat, the thermoelectric elements 21 and 22 arranged in the vertical direction can be controlled to generate cold heat at the same time. The thermoelectric elements 21 and 22 emit cold heat when power is applied, thereby discharging the cold heat generated through the blowing part 40 to lower the sensible temperature.

The heating section 30 can be mounted on the body section 10 and can heat the heat generated by the thermoelectric elements 21 and 22.

The heating unit 30 may be provided with at least a PTC heater and the PTC heater heats up the heat generated by the thermoelectric elements 21 and 22 to maximize the heat generated by the heating unit 30 It can be discharged to the outside.

The heating unit 30 may be installed on the upper portion of the air circulation passage and may discharge heated heat through the heating unit 30 through the blowing unit 40.

The PTC heater may be an electric heating element using a PTC thermistor, and the PTC thermistor may have an increased resistance as the temperature rises. That is, although it has a relatively small resistance value at a low temperature, when the temperature reaches a certain temperature, the resistance suddenly increases to suppress current. Therefore, since it can be used as a constant temperature heating element for automatic control in which current is suppressed when the temperature rises to a certain temperature, it is advantageous that it can be used for a heater in which the temperature rises when a current flows.

In other words, the weak heat generated in the thermoelectric elements 21 and 22 can be maximized through the PTC heater, and the heated heat can be discharged through the blowing part 40.

The blowing section 40 can be mounted on the body section 10, and the temperature can be maintained by circulating the air.

The blowing section 40 is provided at least as an air circulating fan, and can circulate the cold heat and the heat generated by the thermoelectric elements 21 and 22. The air circulating fan can discharge the cold heat and the heat generated from the thermoelectric elements 21 and 22 to the outside. Unlike the conventional fan, the air circulation fan can move the air to a long distance, .

The blowing section 40 may be constituted by at least two or more rotating blades, and the shape of the rotating blades may be the same. The speed of the air discharged through each of the rotating blades having the same shape can be constant and the air blowing area of the air can be formed to be the same so that the user can keep the air of almost constant intensity continuously.

Hereinafter, the operation of a cold / warm air fan according to an embodiment of the present invention will be described.

The cold / hot electric fan 1 according to the embodiment of the present invention first activates the on / off button 121 of the controller 12 by connecting the power supply line 60 to the user, Or a heat generating mode can be selected.

For example, when the cold heat generating mode is selected, cold heat may be generated simultaneously in the heat-generating elements 21 and 22 of the thermoelectric module 20, and the generated cold heat may be discharged to the outside through the rotating blow- . Further, when the user selects the heat generation mode, heat can be generated in the heat and cooling elements 21 and 22 of the thermoelectric module 20, and the generated heat is heated by the heating portion 30, 40 to the outside. In addition, the user has the advantage that the temperature of the desired space can be maintained by adjusting the rotation control unit 124. [

The cold / warm air fan 1 can be formed of a relatively light material and has an advantage that it can be easily moved to a desired space by having the handle 11 that the user can grasp. As a result, power consumption can be saved as compared with the conventional cooling apparatus, and cold heat and heat can be efficiently transmitted even to a space where the temperature is not maintained.

Therefore, it can be used as a multifunctional product which is more efficient than the conventional air conditioner and hot air device, can prevent environmental pollution because it does not use a refrigerant such as freon gas or oil, is easy to transport and store, There is an effect.
