Description

[Detailed description of the invention] The present invention relates to a hot air generating unit that is suspended inside a yagura kotatsu which has a rectangular planar shape, and is particularly located on the short side of the yagura kotatsu, far from the heat generating unit installed in the center. The purpose is to provide a hot air kotatsu that allows people to warm themselves to perform effective humidification.

If the heating unit of this kind of conventional kotatsu is equipped with an infrared lamp, a protective mesh is covered at a distance from the infrared lamp so that the person taking the heat does not come into contact with the heated infrared lamp. This was done to prevent the person taking the heat from coming into direct contact with the infrared lamp and getting burned. Of course, the protective mesh itself is heated to a high temperature, and contact with the mesh will cause burns, so the mesh is usually spaced a predetermined distance from the infrared lamp to prevent it from being heated more than necessary. It is provided. As a result, the height of the heat generating unit becomes large, and the effective internal volume within the tower kotatsu is reduced accordingly, which is not desirable as the feet of the person taking the heat come into contact with it. Furthermore, if the main body of the Yagura Kotatsu is rectangular in plan and the heating unit is suspended in the center, there is a drawback that the person sitting in the longitudinal direction of the Yagura Kotatsu body is away from the heat source and is difficult to warm up. Ta.

The present invention has been devised in view of this point, and one embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 designates the main body of the Yagura Kotatsu, which is rectangular in plan and consists of long sides 2, 2 and short sides 3, 3, with legs 4, 4, 4, 4 hanging down from the corners of these parts, respectively. There is. The ceiling part 5 of the main body of the tower kotatsu is constructed by combining a plurality of cross-linked crosspieces 6, 6, . . . vertically and horizontally.

Reference numeral 7 denotes a hot air generation unit that is suspended on the central ceiling of the Yagura Kotatsu body 1 and heats the inside of the Yagura Kotatsu body.The hot air generation unit is equipped with an electric blower fan 8 and two rod-shaped infrared rays. The lamps 9, 9 are installed in parallel on both sides of the electric blower fan 8, and the inside of the yagura kotatsu main body 1 is heated by the heat rays radiated from the rod-shaped infrared lamps 9, 9 and the circulation of air from the electric blower fan 8. That's what I do.

The warm air generating unit 7 has air guide plates 11 superimposed below the uppermost unit top plate 10 at a distance S, and a motor M of the electric blower fan 8 is disposed between these two plates. . The wind guide plate 11 has its substantially central portion bulged downward to form an inverted truncated cone-shaped inclined surface 12 on the lower surface, and a motor storage space 13 in which the electric motor M can be accommodated in a swingable manner on the upper surface. ing. The electric motor M is elastically supported by the wind guide plate 11 in the vertical direction via a spring 14. The drive shaft 15 of the electric motor M passes through the wind guide plate 11 and has an axial fan 16 supported at its tip and rotates, so that the wind is sent toward the wind guide plate 11 as shown in the arrow direction. The air is smoothly distributed radially along the wind guide plate 11 using the inclined surface 12 as a guide.

Outer peripheral frames 17, 17, 17, 1 are provided on the four sides of the unit top plate 10 and the wind guide plate 11, respectively.
7 are formed in a hanging manner, and through holes 18, 18, consisting of a plurality of horizontally long slits, are bored in the outer peripheral frame, and a net-like body 19, which is made by flocking a lath board, is formed in the lower opening formed by the outer peripheral frame. It is covered.

The rod-shaped infrared lamps 9, 9 are placed between the electric blower fan 8 and the outer peripheral frame 17 consisting of four sides, and are suspended along a pair of opposing outer peripheral frames. The heat rays directly irradiate and heat the feet of the person positioned below the net-like body 19 through the net-like body 19.
is irradiated and heated, and the wind guide plate 11 is further heated.The central side of the net-like body 19 corresponds to the suction port of the electric blower fan 8 that is driven, and the heated net-like body 19 Heat is sequentially radiated by the air flowing in the direction of the arrow. The wind guide plate 11 also radiates heat by air, and the heat is sequentially released from the through holes 18, 18, . Of course, since the hot air that has exchanged heat with the lamps is released from the outer frames 17, 17 on the two sides along which the rod-shaped infrared lamps 9, 9 lie, the temperature is higher than the hot air released from the outer frames 17, 17 on the remaining two sides. becomes.

Therefore, the surface of the net-like body 19 is always maintained at a relatively low temperature without being heated more than necessary, and the hot air emitted from the hot air generating unit 7 is connected to the opposite side where the high temperature hot air is emitted and the low temperature hot air is emitted. This forms the opposite sides. In addition, near both ends of the lamp, it is difficult for the lamp's own hot air to be received, and the temperature in that area becomes low, but it is affected by the heat from the other lamp, so heating is almost uniform on the opposite sides where low-temperature hot air is released. is obtained.

Since the present invention is as described above, the overall height of the unit can be reduced, the effective internal volume within the Yagura Kotatsu can be increased, making it easier to heat the kotatsu, and even if the kotatsu comes in contact with the net, it will not cause burns. Furthermore, there is no need to worry about the risk of injury, and a warm-warming person can comfortably warm himself at any position on the main body of the tower kotatsu, which has a rectangular planar shape, thereby providing a safe, easy-to-use, and practical warm-air kotatsu.
