Electric hot air heater of high pressure

The present invention relates to an electric high pressure hot air blower, and more specifically, an electric high pressure that can increase the temperature of air quickly by ensuring a sufficient time for the air to be heated by making the structure of the hot air cooler slower. It is about a hot air fan.

In general, a hot air fan is used to maintain a constant temperature by supplying hot air to a limited space, and mainly consists of a structure that heats the heat medium using a heat source and then transfers it to where necessary.

However, conventionally, the heat medium is mainly made of water to make a high pressure and use a high temperature temperature. When water is used, excessive time and fuel are required to raise the water temperature to an appropriate temperature, and also maintained in relation to corrosion and scale. It was difficult to manage and also costly to maintain, and could not be used outside the limited temperature by steaming the water.

In addition, since the heat source is generally gas or oil, it is very difficult to control the exothermic temperature, and in some cases, the operating system temperature of the heat medium pipe is often exceeded, and the use of the heat source is avoided despite the high energy efficiency.

In addition, when air is used as a heat medium, the externally supplied air passes through the heat source within a relatively fast time, so the contact time with the heat source decreases, thereby reducing the thermal efficiency and consuming much fuel to raise the supplied air to an appropriate temperature. There has been a problem.

Accordingly, the present invention has been made to solve the above problems, by using air as a heat medium, safe and low environmental costs when using, and also increase the temperature of the introduced air to an appropriate temperature within a short time It is an object of the present invention to provide an electric high pressure hot air fan that can increase the thermal efficiency by the structure that can be.

And according to an embodiment of the present invention, the air heating member is characterized in that it further comprises an air diffusion plate of a predetermined height provided along the through groove.

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

First, Figure 1 is a view showing an overall perspective view of the electric high pressure hot air blower according to the present invention, as shown in the hot air blower 100 is a sealed cylindrical shape of the supply pipe 10 is connected to the compressor (not shown) on one side Is formed in, the discharge pipe 90 through which the air pressurized through the supply pipe 10 is discharged back to the outside is formed on the upper side of the hot air fan 100 of the present invention, respectively.

In addition, at least one electric heater 20 is disposed at the other side of the hot air fan 100 to heat the air introduced into the inside at an appropriate temperature, and the electric heater 20 receives a separate electricity from the outside. It is preferable that the number of the heaters to be heat-generated is appropriately variable according to the user's selection or use conditions, and is detachable from the hot air blower 100 for convenience in repair or maintenance.

As shown above, the hot air fan is made of a very compact configuration, so that the hot air fan can be easily installed and operated in a required place, thereby providing convenience in use.

On the other hand, Figure 2 is a perspective view characteristically showing the main part of the internal structure of the electric high pressure hot air according to the present invention, Figure 3 shows an internal cross-sectional view, respectively.

As shown, the hot air blower of the present invention is largely formed in the outer case 30 and the inner case 40, and the space between the air flow path 80 and the deceleration members 50, 50 ', 50 ", Air blocking members (60, 60 ', 60 ", 60"') and air heating members (70, 70 ', 70 ", 70"') formed in the inner case (40), and the air flowing from the compressor The supply pipe 10 and the discharge pipe 90 for discharging the air heated inside the outside to be configured.

Here, the hot air blower 100 is a double partition structure having an air flow path 80 between the outer case 30 and the inner case 40, the air flow path 80 is a plurality of air through holes 52 ) Is provided with a reduction member (50, 50 ', 50 "), wherein the reduction member (50, 50', 50") is provided through the supply pipe 10 as shown in the lower portion of the inner case (40) At least one is installed on the air flow path 80 between the air inlet 55 formed on the side.

And at least one of the reduction member (50, 50 ', 50 ") is formed so that the diameter of the air through-hole 52 is relatively small toward the air inlet 55 from the supply pipe 10, the pressurized air Is to be passed only through the air through 52 to flow to the lower side of the air flow path (80).

On the other hand, an air inlet 55 is formed at the lower side of the inner case 40 mounted inside the outer case 30, and air is introduced into the inner case 40 through the inlet 55.

In addition, the inner case 40 has air blocking members 60, 60 ', 60 ", 60"' having a diameter smaller than that of the inner case 40, and an inner diameter and a diameter of the inner case 40. The same air heating members 70, 70 ', 70 ", 70"' are alternately installed at least one or more in the vertical direction.

Here, the air heating member (70, 70 ', 70 ", 70"') is a through groove 74 of a predetermined size used as an air passage (space portion in which the electric heater in the drawing), and the through groove 74 The electric heater 20 is installed in each of the heaters to heat the air passing through, so that the air introduced into the inner case 40 through the air inlet 55 is heated through the electric heater 20 This is finally discharged to the outside through the discharge pipe 90 formed on the upper side.

Here, reference numeral 72 denotes an air diffusion plate 72 having a predetermined height installed along the through groove 74.

FIG. 4 is a sectional view taken on the basis of A-A 'in the drawing shown in FIG. 3 and mainly showing the air blocking member.

As shown, the air blocking member 60 "is fixed by the fixing stand 62 in a state spaced apart from the inner case 40 at a predetermined interval, and at this time, air passes from the lower side to the upper side only at the interval. The interval may be optimally selected in consideration of the efficiency of the entire hot air fan.

FIG. 5 is a sectional view taken on the basis of B-B 'in the drawing shown in FIG. 3 and mainly showing an air heating member.

Since the air heating members 70, 70 ', 70 ", 70"' have the same diameter as the inner diameter of the inner case 40 to block the inner flow, the through groove 74 having a predetermined size used only as an air passage. Only the lower side air can pass through the through hole, and the through-hole 74 is provided with an electric heater 20 for heating the air passing through.

The operation of the electric high pressure hot air fan according to the present invention configured as described above will be described in detail based on the bar shown in FIGS. 1 to 5.

First, when the compressed air is blown through the supply pipe 10 using a compressor (not shown) installed on the outside, the introduced pressurized air is formed between the outer case 30 and the inner case 40 at a very high speed. Pass through the air flow path (80).

At this time, the air flow path 80 is provided with at least one reduction member (50, 50 ', 50 "), the inflow of the air is blocked by the reduction member (50, 50', 50") speed is reduced And the introduced air is passed only through the plurality of air through holes 52 formed in the member, so that the air flow rate is reduced overall.

In particular, in the case of the present invention, the air through holes 52 formed in the deceleration members 50, 50 'and 50 "are formed so that the diameters of the air through holes 52 gradually decrease from the supply pipe 10 toward the air inlets 55. When the flow rate is suddenly reduced by the deceleration members 50, 50 ', 50 ", it serves to break up the large air masses more finely in sequence while mitigating the large pressure difference between the upper and lower ends, thereby gradually decreasing the flow rate. To lower it.

At this time, the number of the through holes 52 formed in each of the reduction members 50, 50 ', 50 "is the closing ratio (BR), that is, BR = 1-(sum of the area occupied by the air through / reduction member It is preferable that the value defined as the total area of N is selected to be slightly higher toward the air inlet 55 from the supply pipe 10 along the air flow path 80, that is, from the upper side to the lower side. It can be finally selected in consideration of the condition of the heated air coming out through the discharge pipe.

Therefore, the air pressurized through such a structure is guided to the lower side in a state where the flow rate is lowered gently, and is introduced into the inner case 40 through the air inlet 55 formed at the lower side of the inner case 40. .

On the other hand, the air introduced into the inner case 40 first hits the air blocking member 60 and is introduced into the upper side between the inner case 40 formed on the edge and through the space, the air introduced into the upper side is air The air introduced while hitting the heating member 70 passes only through the through-groove 74 formed on the air heating member 70.

At this time, the through-hole 74 is provided with an electric heater 20 according to the present invention, the air passing through the through-hole 74 is to be heated to an appropriate temperature by the electric heater (20).

In particular, in the present invention, as shown in FIG. 3, the air diffusion plate 72 is installed along the through groove 74, and the air diffusion plate 72 is formed at a predetermined height so that the air has a predetermined height. As it spreads through the diffusion plate 72 and spreads through the entirety of the through holes 74, the contact area with the electric heater 20 installed in the through holes 74 is widened, which is very useful for efficiently heating air. do.

In this way, the heated air is introduced into the upper side through the through-groove 74 and hits the air blocking member 60 'again, which slows down the process of advancing the air and further heats the electric heater (70) of the air heating member 70'. The temperature of air gradually rises in repeated contact with 20).

That is, in the case of the present invention, at least one air blocking member 60, 60 ', 60 ", 60"' and the air heating member 70, 70 ', 70 ", 70"' are alternately installed to be introduced. Air is impeded by the air blocking members 60, 60 ', 60 ", 60"' to spread the air to the edges, slowing the air flow, and subsequently installed air heating members 70, 70 ', 70 ", 70 "') collects the air spread through the through groove 74 again, and the air is gradually heated as the air is concentrated to repeat the process of intensive heating using the electric heater 20. It will proceed to the upper side.

Therefore, as the air progressing process is slowed down, the internal pressure can be increased, and sufficient time can be secured to heat the air, and due to the repetitive electric heater and the flow structure, the temperature rises to a proper temperature even with a relatively small amount of electricity supply. Not only is this possible, it is also possible to maintain a relatively high temperature of air continuously.

To this end, in the present invention, the heating temperature of the electric heater is sequentially controlled so as to become higher toward the upper side so that the air passing through the through groove is gradually heated to a high temperature, or it is linked with the temperature of the final discharged air. It is desirable that the amount of air blocking member and air heating member be adjusted so as to be installed and used under optimum conditions by sufficiently examining the amount of electricity supplied.

In this way, the heated air in the state heated to the appropriate temperature is finally discharged to the outside through the discharge pipe formed on the upper side.

On the other hand, when the air introduced by using the compressor as in the high pressure state as in the present invention, the temperature of the inlet air is increased by that much, and the air can be heated to an appropriate temperature within a faster time, and also the progress of the internal air Due to this slow structure, the relatively high pressure is advanced so that the heated air can be sufficiently discharged through the outlet.

As described above, in the case of the embodiment of the present invention, only the heated air is discharged to the outside. However, the person skilled in the art uses the heated air as a heating or the like according to the intended use, and then circulates it again. It is also possible to be modified in any way, and also to provide a control unit for controlling the heating temperature of the electric heater to efficiently operate the operation and temperature management of the hot air is also a range that can be sufficiently changed if the hot air structure made of the present application. can do.

In the case of using the electric pressurized hot air blower of the present invention as described above, the following effects are expected.

First, accurate heat generation temperature control is possible by using an electric heater, and also has a flow structure capable of sufficiently heating time of air, so that even a small amount of electricity supply can reach a proper temperature within a short time.

In addition, the use of air as a heat medium is less loss due to waste heat, there is no waste water and chemical use, environmentally friendly, low facility costs and maintenance costs, and most of all is very useful invention, such as maintenance is very convenient.
