Description

Hot Air Blower {HOT AIR BLOWER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot air fan, and more particularly to a hot air fan having a cross sectional area of an air inlet larger than that of an air outlet.

In a typical home or office, a heater is used for heating in winter. Since a considerable amount of harmful gas is discharged during the combustion process, a heater for burning a fuel such as oil or gas requires periodic ventilation and the efficiency of heating is lowered, so that a heater using electricity is widely used in recent years.

As one type of electric heating apparatus, there is a hot air type in which air is sucked and heated air is discharged through a heating element. For this purpose, it is necessary to design the cross-sectional area of the air intake port to be larger than the cross-sectional area of the air discharge port. However, in order to simplify the structure of the air intake port There is a disadvantage that the volume of the hot air fan becomes large when the sectional area of the intake port is designed to be wide.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. , ≪ / RTI > equivalents, and alternatives.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals are used to designate identical or similar elements, and redundant description thereof will be omitted.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is an illustration of a hot air fan in accordance with the present disclosure;

2 is an exemplary view showing an internal configuration of a fan according to the present invention;

Referring to FIGS. 1 and 2, a fan 100 according to the present invention may include a housing 110, a heat exchanger 120, and a fan 130.

The housing part 110 may include an upper case 111 and a lower case 112. An air outlet 113 may be formed on the upper surface of the upper case 111. An air inlet 114 may be formed on a lower surface of the lower case 112. The upper case 111 and the upper case 111 The lower case 112 is connected by an assembly. The assembly will be described in more detail below.

The heat exchanging unit 120 may be installed inside the upper case 111 and include a heat generating unit 121 and a heat dissipating plate 122.

According to one embodiment of the present invention, the heating body 121 includes a base substrate, electrodes formed on one side of the base substrate, a heating layer stacked on one side of the base substrate on which the electrodes are formed, Or a planar heating element including a protective layer.

The substrate may include at least one of Silica glass, Quartz glass, Glass-fiber sheet, heat-resistant glass, ceramic glass, and ceramic substrate.

The heating layer may be formed of at least one selected from the group consisting of ITO (Indium Tin Oxide), IZO (Indium Zinc Oxide), ZnO (Zinc Oxide), SnO 2 (Tin Oxide), ATO (Antimony Tin Oxide), AZO Oxide, and FTO (Fluorine Tin Oxide).

The heating element is described in detail in Korean Patent Laid-Open Publication No. 2014-0124107 (heat-generating glass), and a detailed description thereof will be omitted. Further, the above-mentioned heating elements are all incorporated in Korean Patent Laid-Open Publication No. 2014-0124107 (heat-generating glass).

The air supply unit 130 may include a motor 131 and a fan 132 mounted inside the lower case 112 to send the air introduced from the air inlet 114 toward the heat exchange unit 120 have.

In addition, the hot air fan 100 according to the present invention may further include a control unit (not shown) for receiving a user input and controlling power supply to the motor 131 and the heat emitting unit 121 and the like. The control unit can control a display unit (not shown) for user convenience as well as an operation control and a safety control of a general hot air fan. It should be noted, however, that the detailed control method is not described because it is not a key point in this specification.

Hereinafter, a schematic operation of the fan 100 according to the present invention will be described. Electric power is supplied to the motor 131 and the heating body 121 by a user's operation by the motor 131 and the fan 132. Air is introduced into the housing part 110 through the air inlet 114 by the motor 131 and the fan 132. [ The temperature of the sucked air is increased through the heat exchanging unit 120 and is discharged to the outside through the air outlet 113. [

Meanwhile, as described above, in order to obtain a high efficiency of the hot air fan, a hydrodynamic structure capable of sucking a large amount of air and supplying it to the heat exchanger 120 is required. However, when the sectional area of the air intake port is designed to be wide, the entire volume of the hot air fan is disadvantageously increased.

The external appearance of the hot air fan 100 may be deformed by the assembly connecting the upper case 111 and the lower case 112 according to the present invention. At this time, the outer surface of the deformed hot air fan may form an additional air inlet in addition to the air inlet 114 formed in the lower case 112. The fan 100 according to the present specification through the additional air inlet can achieve high efficiency.

3 is an exemplary view of a hot air fan according to an embodiment of the present invention.

Referring to FIG. 3, it can be seen that the upper case 111 is moved upward. The upper case 111 and the lower case 112 are connected to each other by an assembly 140. In this case, the upper case 111 and the lower case 112 are vertically extended It may have a structure that allows it to be. In one example, the assembly 140 may have a multi-tiered structure applied to a tripod for antenna or camera support. As another example, the assembly 140 may be formed with protrusions (or grooves). The upper case 111 or the lower case 112 may have grooves (or protrusions) formed at positions corresponding to the protrusions (or grooves) formed in the assembly. Therefore, when the upper case 111 is moved upward, the shape of the outer shape of the housing can be fixed by the protrusion and the groove.

4 is an exemplary view of a fan according to another embodiment of the present invention.

Referring to FIG. 4, it can be seen that the upper case 111 is slightly rotated clockwise. The upper case 111 and the lower case 112 are connected to each other by an assembly 140. In this case, the upper case 111 and the lower case 112 are rotated clockwise or counterclockwise And can be rotated in the clockwise direction. It is obvious that the structure of the assembly 140 can be variously implemented by a known technique applicable to the technical field of the present invention, and a detailed description thereof will be omitted.

According to the embodiment shown in FIG. 3 or FIG. 4, it can be confirmed that an additional air inlet is formed due to a change in the appearance of the housing part 110. It can be confirmed that the additional air intake port is formed above the air-blowing unit 130 and below the heat-exchanging unit 120. Accordingly, when the motor 131 and the fan 132 are operated, a flow of air flowing by the inside of the housing part 110 is generated, The air existing between the case 111 and the lower case 112 is sucked in. In general, the specifications of the motor 131 and the fan 132 are designed according to the area of the air inlet. However, even if the fan 100 according to the present invention selects a specification according to the area of the air inlet, it can exhibit performance corresponding to the area of the additional air inlet. Accordingly, It is possible to supply the hot air to the fan unit 120. Further, since the fan unit 100 is deformed at the time of operation, a minimized appearance can be maintained during storage and movement.

Meanwhile, the size of the upper case 111 may be adjusted to the size of the heat exchanging unit 120. In addition, the size of the lower case 112 can be made to be suitable for the size of the wind-up part 130. That is, the distance between the heat exchanger 120 and the airflow 130 can be obtained by the deformation of the assembly 140 during the operation of the hot air fan, It may be manufactured to have a minimum volume in accordance with the size of the light emitting unit 120 and the light emitting unit 130.

Meanwhile, in the hot air fan 100 according to the present invention, an air outlet 113 is formed on the upper surface of the upper case 111. Therefore, it is necessary to prevent the possibility that a fluid such as water can flow from the outside through the air outlet 113.

5 is a cross-sectional view of an air outlet according to an embodiment of the present invention.

5, the air outlet 113 according to the present invention includes a fluid inflow blocking surface 115 having a predetermined inclination with respect to a direction perpendicular to the paper surface, And a drain groove 116 formed at one end adjacent to the fluid inflow and blocking surface 115 in the transverse direction of the fluid inflow and blocking surface 115. At this time, one end of the drainage groove 116 is installed lower than the other end, so that the fluid introduced into the drainage groove 116 can flow in the one end direction. Preferably, the fluid inflow blocking surface 115 may have a length that can cover a drain groove (not a drain groove connected thereto) connected to another adjacent fluid inflow blocking surface. Therefore, when the air outlet 113 is viewed from above, the heat exchanger 120 is not visible. On the other hand, the heated air can escape through the fluid inlet / outlet faces 115.

It will be apparent to those skilled in the art that the present specification may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present specification should be determined by rational interpretation of the appended claims, and all changes within the equivalency range of the specification are included in the scope of the present invention.
