Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a hot air blowing unit in which hot air generated from the unit body is guided to a desired position by a hot air guide pipe.

Recently, devices that dry futons or dry clothes using hot air discharged from the main body of the unit have become popular, and when drying futons, a cloth bag member is interposed between the upper and lower futons, and hot air is pumped into the cloth bag member. The futon is forcibly dried by the hot air released from the grains of the cloth, and when drying clothes, the hot air generated from the unit body is guided into the box where wet clothes are hung using the same hot air guide pipe. I put it in and force it to dry.

That is, a suitable hot air guide pipe is connected between the main body of the unit that generates hot air and the object to be dried.

Such a hot air guide pipe is connected to a hot air outlet of a unit body that generates hot air by fitting a fitting cylinder portion formed at one end thereof. Therefore, if the connection fitting is loose, there is a drawback that if stress is applied to the hot air guide tube in the pulling direction during work, it will easily fall off, and the hot air guide tube is in a separated state when not in use. There was a time when I transferred a tube and lost it.

The present invention has been devised in view of this point and provides a warm air blowing unit that is easy to handle. An example of this will be explained below with reference to figures.
1 is a hot air blower unit body, and inside the box-shaped body 2,
Hot air generator 5 having a blower fan 3 and a heater 4
An air outlet 7 formed at the rear end of the hot air discharge pipe 6 of the hot air generator is positioned opposite to a through hole 9 formed in the wall surface 8 of the box-shaped main body 2.

Reference numeral 10 denotes a hot air guide pipe that is slidable on the hot air discharge pipe 6 and can be freely extended and retracted from the through hole 9. The hot air guide pipe is made into a bellows pipe 11 at both ends so as to be stretchable and bendable. A rear end ring 12 and a front end ring 13 are attached to the rear end ring 12 and front end ring 13, respectively.

When the hot air guide tube 10 is housed in the box-shaped main body 2, the bellows tube 11 is compressed by holding the front end ring 13 of the hot air guide tube and pushing it into the through hole 9. The hot air discharge pipe 6 of the hot air generator 5 is located and stored on the outer periphery of the hot air discharge pipe 6, and a locking protrusion 14 formed on the outer periphery of the front end ring 13 is engaged with the rear edge 15 of the opening of the through hole 9. Store and hold.

Next, when the warm air guide pipe 10 is led out from the box-shaped main body 2, the front end ring 13 of the warm air guide pipe 10 is held and the bellows pipe 11 is expanded, and the rear end ring 13 is pulled out. 12
slides on the outer periphery of the hot air discharge pipe 6 to open the through hole 9.
The hot air guide tube 10 is brought into contact with the rear end edge 15 of the opening to lead out the hot air guide tube 10 to a desired position.

Reference numeral 16 denotes a filter attached to the rear end surface 17 of the box-shaped main body 2, and is attached to an intake port 18 through which outside air is drawn in when the hot air generator 5 is driven. Reference numeral 19 denotes a power cord for supplying electricity to the blower fan 3 and the heater 4 of the warm air generator 5.

As mentioned above, the hot air blowing unit of the present invention has a slidable and expandable warm air guide pipe externally installed on the hot air discharge pipe of the hot air generator disposed inside the box-shaped main body, and Since the tube is made to be able to come out and go out through the through hole drilled in the wall of the box-like body, when hot air is being drawn out, the necessary length of the hot air guide tube can be directly drawn out, so that the hot air guide tube does not get in the way. In addition, the hot air guide tube is formed with a locking protrusion whose front surface engages with the opening edge of the through hole when the hot air guide tube is housed in the box-shaped main body. Therefore, it will not fall out unnecessarily. Furthermore, when not in use, the hot air guide tube can be stored inside the box-like main body, so there is no need to worry about losing it. Since the expandable hot air guide tube is slidable along the outer peripheral wall of the hot air discharge tube, hot air can still be discharged from the hot air guide tube even when the hot air guide tube is stored. For example, it can also be used as a hot air fan.
