Description

[0001] Hot-air blower having humidification function [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifying type hot air fan installed in a structure having a large indoor space such as a vinyl house or a house.

Generally, vinyl house is a facility for cultivating various crops regardless of the season. When cultivating crops in winter season, it is necessary to keep the temperature of the vinyl house appropriately. Maintaining the inside of the vinyl house at a proper and constant temperature requires cultivation Is the most important factor.

Generally, when heating a greenhouse, briquette is used. However, it is heated by using electric hot wind or oil hot wind which is convenient.

As described above, the hot air blower using the electricity and the oil as the energy source heats the entire wide indoor space such as the vinyl house and the house by supplying the hot air in one direction. Since the heat is not uniformly distributed throughout the room, There is a difficulty.

Particularly, in the case of the vinyl house, the crops are well grown in the places where the heat is uniformly distributed, and the crops are cold-weathered in the places where the heat is not generated.

In order to solve such a problem, a long plastic bag or the like is provided at the hot air inlet of the hot air blower, and a certain amount of hot air is supplied in the longitudinal direction by supplying a hot air through a hole in the outer surface of the long plastic bag. There is a disadvantage that the temperature of the inlet where the hot air is supplied is relatively high and the effect at the end portion located at the opposite side of the inlet is low because the temperature is low.

Also, in the case of the conventional hot air fan, there is a problem that the economical burden of the farmer is increased due to excessive consumption of electricity and oil because the hot air fan must be operated continuously without resting to maintain the temperature of some room in the room.

On the other hand, there are various prior arts related to the conventional hot wind. Some of these prior arts are introduced.

Korean Patent No. 10-1462629 (Nov. 11, 2014) discloses a "regenerative-style fan heater ".

A heat exchanger in which a heating medium is circulated and a circulating heating medium is circulated with the circulating heating medium; and a heat exchanger which is connected to the heat exchanger so as to be connected to the heat exchanger, And a press-feeding section for discharging the heated air in the heat exchanging section to the inside of the structure while circulating, and for feeding the air inside the structure to the hot-air circulating and discharging section side.

This prior art, however, has a structure in which a long plastic bag is installed in a conventional hot air blower by circulating air using a blower of an exhaust port, and the uniformity of heat is realized by the same principle as the method of using a hole, And has a disadvantage of high heat loss.

Korean Patent No. 10-1107286 (2012.01.11) discloses "hot air heating apparatus for agricultural use ".

This is a method of supplying and circulating the air discharged from the heat exchanging unit to the inside of the vinyl house in the manner of using a heating medium and supplying the circulated air to the heat exchanging unit again. In order to uniformly supply heat to the inside, the size of the hot air discharge hole of the hot air discharge pipe is differently formed at the inlet and the end portion, and the size of the hot air discharge hole must be controlled by the designer differently, have.

On the other hand, the flowering house, the cultivation house, the barn house and other plastic houses can be supplied with hot air directly by using harmony, briquettes and oil, installing pipes on the indoor floor, supplying hot water to the pipes, It is common to heat by circulating hot water.

When piping is installed on the floor of the room and the hot water is circulated, it takes a long time to heat up, and since the room air stagnates, the air flow is not smooth and the room humidity gradually decreases There is a problem that a high installation cost is required.

When a radiator is used, heating is performed only in a region where the radiator is installed. If a plurality of radiators are installed for heating, there is a problem that space utilization is lowered and cost is increased.

It is to be understood that the foregoing description of the background art has been presented for the purpose of understanding the background of the present invention and is not to be taken as admission that the prior art is known to those skilled in the art.

The objects, particular advantages and novel features of the present invention will become more apparent from the following detailed description and examples taken in conjunction with the accompanying drawings. It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements are assigned the same number as much as possible even if they are displayed on different drawings. Also, the terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, a humidifying type hot air fan according to the present invention will be described with reference to the accompanying drawings.

1 and 2, the humidifying type air conditioner of the present invention includes an inner tube 10, an outer tube 20, a heating medium 30, a discharge blower 40, and a humidifying fluid supply unit 50.

The inner tube 10 can be formed in various shapes. In the present invention, the inner tube 10 is formed into a hollow cylindrical shape. The inner pipe 10 is formed long so that air can pass through it.

The outer tube 20 may be formed in various shapes like the inner tube. In the present invention, the outer tube 20 is formed into a hollow cylindrical shape like the inner tube 10. The shape of the inner tube 10 and the outer tube 20 is preferably formed in the same shape so that the inflow of air and the flow of air can be smoothly performed.

The diameter of the inner tube 10 must be smaller than the diameter of the outer tube 20 so that the inner tube 10 is embedded in the outer tube 20 and the length thereof should be shorter than the length of the outer tube 20 as well. That is, in order for air to flow in from outside, a predetermined gap I must be formed between the inner circumferential surface of the outer tube 20 and the outer circumferential surface of the inner tube 10 so that the diameter of the inner tube 10 is smaller than the diameter of the outer tube In order for the air flowing in the gap I between the inner circumferential surface of the outer tube 20 and the outer circumferential surface of the inner tube 10 to flow into the heat medium 30, one end of the inner tube is inserted further into the outer side than the one end of the outer tube The length of the inner tube 10 should be shorter than the length of the outer tube 20. [ 1 and 2, a space may be formed between one end of the inner pipe 10 and one end of the outer pipe 20 to allow air to flow into the heating medium 30. In this case, 10 and the length of the outer tube 20 are not necessarily required.

One end of the outer tube 20 must be sealed so that the air flowing through the gap I formed between the inner circumferential surface of the outer tube 20 and the outer circumferential surface of the inner tube 10 flows and flows into the heating medium 30. [

The heating medium 30 is embedded in one end of the inner tube 10 to heat the air. The specific structure of the heating medium 30 will be described later.

A discharge blower (40) is installed inside the other end of the inner pipe (10).

The exhaust blower 40 is installed inside the other end of the inner pipe 10 and sucks the heated air existing in the inner pipe 10 through the heating medium 30 and is heated to the indoor space outside the inner pipe 10 Air is exhausted. As the heated air existing in the inner pipe 10 is discharged to the outer space of the outer space, the outer air flows into the space I formed between the inner circumferential surface of the outer pipe 20 and the outer circumferential surface of the inner pipe 10, Reaches one end of the outer tube (20) and the inner tube (10), and then flows into the heating medium (30). That is, when the discharge blower 40 is operated, the heated air passing through the heating medium 30 can be discharged to the outside, and the outside air is also flowed, so that the air can flow smoothly.

The humidifying type hot air fan of the present invention includes a humidifying fluid supplying part 50 for supplying a humidifying fluid to humidify the air flowing into the heating medium 30. The humidifying fluid supply part 50 is provided with a reservoir (not shown) for storing the humidifying fluid to the outside and connects the reservoir and the outer pipe 20 with the supply pipe 52, Time). That is, the humidifying fluid, which is once connected to the reservoir and flows into the outer tube through the supply pipe 52 connected to the other end to communicate with the outer tube 20, is injected into the air flowing into the heating medium 30, It is to be adjusted.

On the other hand, the outer tube 20 may include a first outer tube 22 and a second outer tube 24.

The first outer tube 22 and the second outer tube 24 are spaced apart from each other in the longitudinal direction, and the inner tube 10 may be exposed at a spaced distance. One end of the inner tube 10 may be embedded in the first outer tube 22 and the other end of the inner tube 10 may be embedded in the second outer tube 24. [

One end of the first outer tube 22 is sealed with the first cap C1 and a gap formed between one end of the second outer tube 24 and the inner tube 10 is sealed with the second cap C2.

One end of the inner tube 10 is inserted further into the first outer tube 22 than one end of the first outer tube 22 and air is introduced between one end of the first outer tube 22 and one end of the inner tube 10. [ A space is formed which can flow. That is, after the air flows into the space I formed between the inner peripheral surface of the other end of the first outer tube 22 and the outer peripheral surface of the inner tube 10, the introduced air flows in the direction of one end of the first outer tube 22, And reaches the space formed between one end of the inner pipe 22 and one end of the inner pipe 10, and then flows into the heating medium 30 provided inside the inner pipe 10.

The first cap C1 is coupled to one end of the outer tube 20 to prevent air from the outside from reaching one end of the first outer tube 22 and one end of the inner tube 10 and flowing out to the outside, The cap C2 is a structure for preventing the outside air from flowing in a direction other than the direction in which the heating medium 30 is installed.

The other end of the inner tube 10 is protruded from the other end of the second outer tube 24 in the longitudinal direction by a predetermined length and the outer surface of one end of the first outer tube 22 is provided with a temperature control panel The sensor pipe P may include a temperature sensor 70 and a temperature sensor 70. The temperature sensor 70 may be installed on the outer surface of the outer tube 20, One end of the second outer tube 24 may protrude further in the longitudinal direction than the other end of the inner tube 10 protruded from the other end of the second outer tube 24. [

The temperature control panel 60 controls the temperature of the heating medium 30 so as to adjust the temperature of the room temperature To meet the set temperature. At this time, the temperature sensor 70 measures the temperature of the heated air discharged from the inner pipe 10 by the discharge blower 40 in real time and transmits the information to the temperature control panel 60. That is, the temperature sensor 70 is further protruded from the second outer tube 24 than the inner tube 10 so that the temperature sensor 70 can more accurately measure the temperature of the heated air discharged from the inner tube 10 .

The temperature control panel 60 controls the internal temperature of the heating housing 32 by adjusting the amount of heat generated by the heating heater 34 by adjusting the electric power applied to the heating heater 34 And if the temperature measured by the temperature sensor 70 does not reach the set temperature, the amount of heat generated by the heater 34 or the amount of air blown by the discharge blower 40 can be adjusted. If necessary, The amount of humidifying fluid introduced from the supply unit 50 may be adjusted.

3 is a view showing another embodiment of the humidifying type air conditioner of the present invention.

3, another embodiment of the humidifying type air conditioner of the present invention includes an outer tube 20 including an inner tube 10, a first outer tube 22 and a second outer tube 24, a heating medium 30, An exhaust blower 40, and a humidifying fluid supply unit 50.

The inner tube 10, the outer tube 20, the heating medium 30 and the humidifying fluid supply unit 50 of the other embodiment of the present invention are similar to those of the above-described embodiment of the present invention. The description will be centered on the installation structure of the exhaust blower 40, which is different from the embodiment of the present invention.

According to another embodiment of the humidifying type hot air fan of the present invention, the discharge blower 40 is installed on the outer circumferential surface of the outer tube 20, and a plurality of the discharge blower 40 are spaced apart from each other by a predetermined distance.

3, there is shown a humidifying type hot air fan equipped with three discharge blowers 40, but the number of the discharge blowers 40 may be variously set according to the designer's intention.

When the exhaust blower 40 is operated, an air flow is generated inside the first outer pipe 22, the second outer pipe 24, and the inner pipe 10.

The air between the inner circumferential surface of the second outer tube 24 adjacent to the discharge blower 40 and the outer circumferential surface of the inner tube 10 is discharged to the outside through the discharge blower 40 according to the operation of the discharge blower 40. [ At the same time, the air existing inside the inner tube 10 built in the second outer tube 24 flows to the other end of the inner tube 10 and again flows into the space between the inner peripheral surface of the second outer tube 24 and the outer peripheral surface of the inner tube 10 .

The air heated and passed through the heating medium 30 moves to the other end of the inner tube 10 and the outside air flows into the space I formed between the inner circumference of the first outer tube 22 and the inner tube 10 And then flows into the heating medium 30.

The air heated while passing through the heating medium 30 flows inside the inner tube 10 and the heat loss is generated as the flow distance becomes longer. As the distance from the heating medium 30 increases, the temperature further decreases. The air discharged from the other end of the inner pipe 10 and flowing between the inner circumferential surface of the second outer pipe 24 and the outer circumferential surface of the inner pipe 10 is discharged to the discharge blower 40. In the discharge blower 40, The temperature of the air discharged from the exhaust blower 40 located farthest from the heating medium 30 is relatively highest and the temperature of the air discharged from the exhaust blower 40 located closest to the heating medium 30 is the lowest , And the temperature of the air discharged from the discharge blower 40 located in the middle thereof is discharged to a medium temperature.

The reason is that, as described above, the longer the distance of air flow, the more heat loss is generated.

According to the present invention, however, thermal radiation is generated from the inner pipe 10 by the heated air passing through the inner pipe 10, and air flowing between the inner peripheral surface of the second outer pipe 24 and the outer peripheral surface of the inner pipe 10 The temperature can be raised. That is, although the air existing in the vicinity of the discharge blower 40 located closest to the heating medium 30 has the largest flow distance from the heating medium 30 to the discharge blower 40, the temperature decrease is the largest, And is heated by the heat emitted from the corresponding inner pipe 10 to generate a temperature increase. The temperature increase due to the heat emitted from the inner tube 10 at this time is due to the heat released from the air having the shortest flow distance from the heating medium 30 and is therefore relatively larger than the temperature increase at other positions of the inner tube 10, It is a temperature increase to the extent that it can fully compensate for one temperature decrease.

Likewise, the air existing in the vicinity of the discharge blower 40 located farthest from the heating medium 30 is relatively shorter in distance from the heating medium 30 than the other discharge blower 40, The temperature increase due to the heat emitted from the inner pipe 10 is relatively smaller than the position of the other inner pipe 10, so that a temperature increase corresponding to the temperature decrease is accurately generated.

The air present in the vicinity of the exhaust blower 40 located in the middle also has a temperature decrease and a temperature increase due to the above-described principle.

When the temperature of the air discharged to the discharge blower 40 is compensated by using the heat radiated from the heated air passing through the inner pipe 10 as described above, The temperature can be uniformly maintained so that the appearance 20 can be adiabatically treated in order to ideally realize the uniformity of the temperature discharged from each of the discharge blowers 40. [

Another embodiment of the humidifying type air conditioner of the present invention may further include a temperature control panel 60 and a temperature sensor 70. Since the description of these configurations is very similar to the embodiment of the present invention, The above description is replaced.

As shown in Figs. 2, 3 and 4 (a) to 4 (c), the heating medium 30 serving as a base of the humidifying type hot air fan of the present invention has a long The heating heater 34 includes a heating housing 32 formed in a hollow shape and a heating heater 34 installed in the heating housing 32. The heating heater 34 may be installed in various shapes.

The heating housing 32 described above may be replaced by an inner tube 10 and a heater 34 directly installed inside the inner tube 10 when the inner tube 10 is replaced.

The heating heater shown in Figs. 2 and 3 is a fin-type heating heater.

The heating heater 34 is provided along the heating housing 32 in a long fin shape on the inner circumferential surface of the heating housing 32. The pin heater heater 34 may be formed in a shape that is long in the flow direction of the air and may be formed in the shape of ". When the heater heater 34 is formed in the shape of", The heating efficiency can be improved since the air can flow while being continuously heated in the horizontal direction. A plurality of the heating heaters 34 may be provided at the center of the heating housing 32, and a plurality of the heating heaters 34 may be provided radially close to the inner wall of the heating housing 32.

The heating heater 34 shown in Fig. 4 (a) is a plate-type or band-type heating heater 34. Fig.

The plate-type or band-type heating heater 34 is closely attached to the inner wall of the heating housing 32, and is installed on the entire inner wall of the heating housing 32. The heating area is the largest, , There is an advantage that the flowing air is not interfered with by the heating heater 34.

The heating heater 34 shown in Fig. 4 (b) has a merit of being a coil type heating heater 34, and the coil type heating heater 34 can smoothly flow the air, The spring-type heating heater 34 shown in FIG. 3 (c) is formed to protrude from the inner wall of the heating housing 32 in a direction perpendicular to the air flow direction, and is formed in a coil shape whose diameter is expanded in the circumferential direction from one end thereof , A plurality of them may be installed at a predetermined interval in the air flow direction.

As described above, according to the humidifying type hot air fan of the present invention, the temperature reduction reduced by the heat loss amount of the air flowing through the inner pipe 10 is transferred to the air discharged from the discharge blower 40, Air having a uniform temperature can be discharged into the indoor space regardless of the installation position of the indoor unit 40.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be apparent that modifications and improvements can be made by those skilled in the art.
