Description

[Detailed explanation of the idea] The present invention relates to a hot air circulation type heater.

BACKGROUND ART Hitherto, as a heater of this kind, a type having a circulation blower, a gas burner, or other heat source in a housing having an inlet and an outlet for indoor air is known.

The present invention does not directly release the hot air obtained from the outlet of the heater into the room, but rather guides it separately to heat an adjacent separate room, or to perform localized heating. The purpose is to obtain a versatile heater that can be freely used for drying bedding or for drying futons. , which is equipped with a circulation blower 4 and a gas burner or other heat source 5, is a hood-shaped container 9 having an open surface 6 shaped to approximately match the outlet 2, and has a hot air duct 10 on the outer surface. A device having a connecting lower and a blower 8 inside which sucks and blows air to the connecting lower from the open surface 6,
At the periphery of the open surface 6, it overlaps the outer surface of the periphery of the outlet 90 and is detachably attached thereto.

The main body of the heater is not limited to a type in which the indoor air inlet 1 is provided on the lower side and the outlet 2 is provided on the upper side as shown in the first diagram, for example, but it may be reversed as shown in the second diagram, for example. The means for overlapping and removably attaching the container casing 9 to the outer surface of the peripheral edge of the outlet 2 at the peripheral edge of the open surface 6 may include protrusions formed on the peripheral edge. A type in which the grooves are engaged with each other or a type in which a suction cup is used may be used as desired.

In the drawing, 8a indicates the drive motor of the blower 8.

The housing 9 is made horizontally expandable and retractable, as shown in FIGS. 3 and 4, for example, so that it can freely accommodate outlet ports 2 of different sizes depending on the type of heater. It is possible that

In this case, the housing 9 is a central fixed frame 9 that houses the blower 8.
a, and movable frames 9b on both sides that can be freely pulled out laterally.
, 9b, and each movable frame 9b can be fixed with a screw 11 at an appropriate drawer length.

In addition, the connecting lower is a fixed type as shown in Figure 1 or 2,
Alternatively, it may be freely rotatable in any direction as shown in FIGS. 3 and 4.

Further, the heat source 5 is not limited to a gas burner, and may be any other suitable heat source such as an oil burner or an electric heater.

To explain its operation, it is normally used as a normal heater by removing the housing 9 and leaving the outlet 2 open, but when separate warm air is required, the housing 9 is attached as shown. When the blower 8 is operated in this way, the hot air obtained at the outlet 2 is sucked by the blower 8, discharged from the connecting lower, and guided into the duct 10 connected thereto.

Thus, this warm air can be freely used, for example, for heating an adjacent room, central heating, or drying bedding.

In this way, when the present invention is used, the heater can be used not only as a warm air circulating type, but also for separate purposes such as heating an adjacent room, central heating, or drying futons, and thus can be used in a wide range of areas. It has the advantage of being convenient and economical.
