Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a wall-mounted or ceiling-mounted hot air heating device in which a warm air induction is attached downward from the hot air outlet. be.

[Conventional technology] Wall-mounted or ceiling-mounted warm air heating devices have become very popular in recent years because they do not occupy floor space. The structure is such that it blows out a strong stream of warm air. For this reason, when you feel the wind speed or move away a little, you feel a cold breeze, which tends to be uncomfortable.

Therefore, in accordance with the application for utility model registration dated April 4, 1985, the applicant installed a hot air induction body with an internal ventilation passage formed downward from the hot air outlet of the hot air generator, and once the hot air was inside this induction body. We have proposed a heating system that allows the air to flow down to the floor through the ventilation channels and then diffuse into the room, so that the air does not feel cold or windy.

[Problems with the Prior Art] However, in the case of this hot air induction, when the blower fan is rotated weakly, it is not so bad, but when the fan is rotated strongly, the wind flows through the center of the ventilation duct, and the air blows on the seat surface. There is a phenomenon of air retention (static film), which causes the problem that the radiation effect from the sheet surface does not increase commensurate with the air volume.

The purpose of the present invention is to attach a warm air inducer to a wall-mounted or ceiling-mounted warm air heating apparatus, so that the radiation effect from the inducer can be enhanced especially when the air volume is increased. It is.

[Means to solve the problem] The configuration of the present invention is as follows.

A wall-mounted hot-air heating device comprising a wall-mounted hot-air generator with a hot-air outlet facing downward and a flat hot-air induction body with an internal ventilation path extending from the hot-air outlet toward the floor. A wall-mounted hot air heating device comprising a front sheet and a rear sheet that form a hot air guide and are partially joined at appropriate locations.

[Function] The warm air blown from the hot air generator into the ventilation path inside the hot air induction body becomes an obstacle at the joint between the front sheet and the rear sheet while passing through this ventilation path, causing turbulence in various places. Wake up at. As a result, the formation of a static film on the sheet surface is prevented, the heat of the hot air is efficiently transmitted to the sheet surface, the radiation efficiency is increased, and finally it is blown out from the floor side. Furthermore, since the front sheet and rear sheet of the warm air induction sheet are partially joined together, there is no fear that the hot air induction sheet will swell due to wind pressure.

[Example] Fig. 1 shows a wall-mounted hot air heating device to which the present invention is applied. 1 is a hot air generator, and 2 is a warm air heater installed downward from the hot air outlet of the hot air generator 1. As shown in FIG. 2, this warm air guide 2 uses a front sheet 3 and a rear sheet 3' to form a ventilation passage 4 inside, and as shown in FIGS. 3 and 3' are partially connected by strings 5 at appropriate locations. Note that the front sheet 3 and the rear sheet 3' may be partially connected by directly sewing or gluing them together without using the strings 5.
Furthermore, in order to make the temperature distribution uniform, it is effective to make the upper joints denser and to make the joints rougher toward the bottom.

In the ventilation passage 4 of the hot air guide 2, the front seat 3
When the rear sheet 3' and the rear sheet 3' are partially connected as described above, the hot air blown out from the hot air outlet becomes turbulent because the string 5 becomes an obstacle when descending through the ventilation passage 4 in the hot air guide 2. or the flow direction changes. As a result, the static membrane is broken, heat conduction to the sheet surface is improved, and radiation efficiency is increased.

[Effects of the present invention] As described above, the present invention provides the ventilation passage 4 of the hot air guide 2.
The structure was designed in such a way that the partial joints become obstacles, causing turbulence in the hot air and breaking the static film on the sheet surface, which reduces the heat transfer efficiency to the sheet surface, especially when the air volume increases. Never.

As a result, the radiant heat from the warm air induction body 2 increases, and a comfortable heating effect can be obtained.

Furthermore, since the front and rear sheets of the warm air guide 2 are joined at various locations, the appearance will not be damaged by swelling due to the pressure of the wind passing through the ventilation passage 4.
