Description

[Detailed Description of the Invention] The present invention has a compact hot air generator, which makes it easy to install on the ceiling even in an existing room, and quickly generates hot air at any temperature and air volume. At the same time, the generated hot air is distributed and distributed from the top to the bottom of the room by a forced-rotating hot air rotor, changing its position sequentially to quickly dry the items to be dried or to efficiently heat the room. The present invention relates to a hot air drying and heating device that can be used for drying and heating.

A hot air rotor is installed approximately in the center of the upper part of the room, and rotates in one direction due to the reaction of hot air blowing out.
In a hot air drying device that dries objects to be dried using hot air that is distributed and distributed in layers while changing its position sequentially from the top to the bottom of the room, or that effectively heats the room. In order to rotate the hot air rotor in one direction due to the reaction of hot air blowing out, the hot air rotor cannot easily rotate unless a considerable amount of hot air is generated, and the large volume of air can be raised to a predetermined temperature. Therefore, the hot air generator inevitably becomes large and cannot be installed indoors.

Therefore, there is a drawback that it is not possible to easily dry the items to be dried with hot air or heat the room to an appropriate temperature using warm air using an existing room, such as a small room, bathroom, or living room. This is something that was strongly desired to be resolved.

In view of the foregoing, the present invention is equipped with a warm air generator installed approximately in the center of the ceiling of the room, with an intake port opening around the periphery, a ventilation heater fitted on the bottom surface, and a blower housed inside with a shaft mounted downward. Directly below the hot air generator, a hot air rotor with a hot air supply port opened on the surface facing the permeable heater is directly connected to a drive shaft installed vertically from the hot air generator side so that it can rotate slowly in one direction. At the very least, by forcibly rotating the hot air rotor using a drive shaft instead of relying on the hot air blowing reaction, the amount of hot air generated is significantly reduced compared to conventional dry heating equipment. High-efficiency drying and heating operations can be easily carried out even when
The entire hot air generator is made smaller and can be easily installed indoors, making it possible to efficiently dry items to be dried stored in existing small rooms, bathrooms, or small-area boxes using hot air. The present invention provides a hot air drying/heating device that can efficiently heat indoor rooms such as living rooms to an appropriate temperature. Each preferred embodiment shown in FIG.

In the drawing, 1 dries the material to be dried,
Alternatively, it is a room for heating to an appropriate temperature state, and the room 1 refers to a small room, bathroom, or other box during drying, and refers to a living room, etc. during heating. be. Reference numeral 2 denotes a hot air generator for quickly generating hot air at an appropriate temperature, and as shown in FIG. A ventilated heater 5 is removably fitted into the lower surface of the tapered cylindrical main body 3 with a large number of vertically arranged ventilation holes 6, and the upper and lower surfaces are open. A blower 7 is housed in a downward direction for blowing the air sucked into the cylindrical body 3 from the opening 4 toward the breathable heater 5 and blowing out warm air at an appropriate temperature downward. An electric motor 8 that rotates the hot air generator 2 is installed on a support 9 mounted on the upper surface of the cylindrical body 3 in an open position. The warm air generator 2 described above is removably mounted on the ceiling 1' of the room 1 at a substantially central position. 10 is directly connected to a drive shaft 11 installed vertically from the hot air generator 2 side so as to be located directly below the hot air generator 2, and is forced to rotate in one direction at an appropriate rotation speed by the drive of the drive shaft 11. 12 is an electric motor for the drive shaft 11, and 13 is a support member for the drive shaft 11.

The hot air rotor 10 has a bottomed cylindrical boss tube 14 on the circumferential surface of which a hot air supply port 15 is opened on the surface facing the permeable heater 5. A plurality of hollow cylindrical hot air blowing tubes 16 each having a hot air blowing outlet 17 opened along the base end side thereof are installed radially so that the insides thereof communicate with each other. In the present invention, the hot air outlet 17 is opened at a position where it blows out hot air directly downward, but the opening position of the hot air outlet 17 is arbitrary on the circumferential surface of the majority part of the hot air outlet 16. It may be opened at a certain position to blow out hot air in a downward diagonal direction. In addition, the hot air blowing tube 1 mentioned above
It goes without saying that four pieces 6 may be arranged radially as shown by the chain lines in FIG.

In addition, an intake pipe 18 is connected to the intake port 4 opened on the circumferential surface of the hot air generator 2 to supply outdoor air to the hot air generator 2.
Air may be drawn inside. 19 is a lead wire of the breathable heater 5.

The hot air drying/heating device shown in Figures 1 and 2 is mainly installed in a small room or bathroom to dry items to be dried, or installed in a living room to heat the room. In this embodiment, the warm air drying and heating device is installed as it is in a box body 20 as shown in FIG. It is also possible to effectively dry the object to be dried.

In this embodiment, the intake port 4 is not opened on the circumferential surface of the cylindrical body 3 of the hot air generator 2, and the cylindrical body 3
An intake window 2 is opened at approximately the center of the ceiling 20' of the box body 20, with the opening provided on the top surface serving as an intake port 4'.
2 to allow outside air to be drawn into the hot air generator 2. A suitable number of exhaust windows 23 are opened at the lower side of the box body 20 to perform an exhaust action.

The hot air blowing tube 16 used in the hot air rotor 10 described above has a circular cross section as shown in FIG. It may be formed into a downward flat shape like the wind blowing tube 16', and the hot air blowing port 17' may be opened directly below it. In addition, as shown in FIG.
The end edge of the hot air outlet 7'' located at the rear with respect to the rotational direction of the hot air outlet 6'' is extended downward to serve as a stirring blade 24, and the hot air blown out from the hot air outlet 17'' is quickly stirred. It is also possible to make the distribution flow while maintaining the flow.

Moreover, when hot air drying work or heating work is not being performed, the hot air rotor 10 can be removed and the exposed side of the air permeable heater 5 of the hot air generator 2 can be freely inserted into and removed from the cylindrical main body 3, as shown in FIG. It is possible to prevent moisture, dust, etc. from adhering to the breathable heater 5 by covering it with a cover plate 25 fitted into the heater 5.

Next, the operation of the present invention will be explained.

Now, when you want to use room 1 such as a small room or bathroom to dry items to be dried, or when you want to heat the inside of room 1 such as a living room to an appropriate temperature, turn on the electric motors 8 and 12 in the state shown in Fig. 1. When the air blower 7 and the drive shaft 11 are started and the blower 7 and the drive shaft 11 are started, electricity is simultaneously applied to the ventilation heater 5 to bring it into a heated state. Then, as the air blower 7 rotates, the air sucked into the cylindrical body 3 from the intake port 4 is heated, and while it passes through the ventilation hole 6 of the permeable heater 5, heat is exchanged and the temperature is maintained at the appropriate temperature. Hot air blows out from the surface of the drive shaft 1
The hot air flows into the boss tube 14 of the hot air rotor 10, which is forcibly rotated in one direction by the hot air rotor 1, through the hot air supply port 15. The hot air flowing into the boss tube 14 is then transferred to a plurality of hot air blowing tubes 16 arranged radially.
...After the air is evenly distributed and filled, the hot air outlet 1
The air is blown directly downward from 7, forming a layered structure while changing its position one after another. Therefore, the layered warm air is blown as it moves directly downwards in the chamber 1, and the items to be dried are swayed from side to side along the hot air on both sides, allowing them to be dried quickly. Even at times, the room is heated under good conditions by receiving warm air at an appropriate temperature from directly above.

In addition, the rotational speed of the hot air rotor 10 can be freely adjusted by the drive shaft 11, and the amount of hot air can be increased or decreased depending on the rotation speed of the blower 7. More efficient drying or heating operations can be easily achieved by adjusting the rotational speed and volume of hot air to appropriate conditions.

In addition, when it is desired to dry a small volume of drying material using the box body 20 which has both doors 21, 21 pivotably attached to the front surface which can be opened and closed, the hot air generator 2 and the hot air rotor 10 are installed as shown in FIG. If the device is placed approximately at the center of the ceiling 20' of the box body 20 and operated in the same manner as described above, the hot air distributed and distributed from the top to the bottom will dry the air efficiently. The exhaust gas is exhausted to the outside more quickly through the exhaust window 23,
The object to be dried can be dried within a short time.

In short, the present invention provides a heating system in which an intake port 4 is opened around the ceiling 1' approximately in the center of the room 1, a ventilation heater 5 is fitted on the lower surface, and a blower 7 is housed inside with a shaft mounted downward. A hot air rotor 10 is equipped with a wind generator 2, and directly below the hot air generator 2, a hot air rotor 10 having a hot air supply port 15 opened on the surface facing the breathable heater 5 generates hot air so that it can rotate slowly in one direction. Since it is directly connected to the drive shaft 11 installed vertically from the machine 2 side, the hot air generator 2 that generates hot air at an appropriate temperature can be formed into a very small and compact size, making it possible to install it inside the room 1. 1 itself can be used in an existing small room, bathroom, living room, etc., and the hot air generated in an arbitrary amount can be used to easily dry or heat the items to be dried. Rotating rotor 1
Since the air is distributed in a layered manner from the top to the bottom by changing its position, more efficient drying or heating can be easily achieved, and the equipment itself can be made very inexpensive. play.
