より放出される。An example of the above-mentioned conventional technology will be described below with reference to the drawings. 6 and 6 show a conventional hot air fan. In FIG. 5, 1 is a burner that burns fuel. Reference numeral 2 denotes a cylindrical combustion tube which covers the burner 1 and is open at the top, the lower end of which is connected to the seven rungs of the burner 1 and the duct lower plate 3. The duct lower plate 3 forms a box with the duct upper plate 4 placed thereon, and is connected to an air outlet 5 and a blower 6. Further, the combustion tube 2 opened into the duct faces the blower 6 and the air outlet 5. In the hot air fan configured as described above, high-temperature combustion gas burned in the burner 1 is released into the duct from the upper opening of the combustion tube 2, mixed with the air sent from the blower 6, and becomes hot air. Air outlet 5
released.

うに構成された温風機に於いては吹出口5の上部に設け
た冷風吹出口8から温風と同時に冷風が吹き出される。However, in the above configuration, since the hot air discharged into the room is at a high temperature, upward air currents work and the warm air does not reach the corners of the room, resulting in large temperature unevenness between the top and bottom of the room. Therefore, recently the 6th
As shown in the figure, a partition plate 7 is provided between the duct upper plate 4 and the combustion tube 2, and a cold air outlet 8 is provided above the air outlet 5, and this cold air outlet 8 is made vertically movable. 56-16856) has been proposed. In the hot air fan configured as described above, cold air is blown out from the cold air outlet 8 provided above the air outlet 5 at the same time as hot air.
すなわち室内に温風が吹き出された後もその上部に比重
の重い冷風が同時に吹き出される為、温風の上昇気流を
押えて室の隅まで温風を導く事ができ、室内の上下温度
差を少なくし快適で経済的な暖房が可能となる。In other words, even after warm air is blown into the room, cold air with a heavy specific gravity is blown out at the same time, suppressing the rising airflow of hot air and guiding the warm air to the corners of the room, reducing the temperature difference between the top and bottom of the room. Comfortable and economical heating is possible with less heating.

13をふさぐべく位置している。The operation of the warm air fan configured as above will be described below. First, when the switch 17 of the appliance is turned on, the burner motor 2 and pump 3 operate to supply fuel and air to the burr section 1. The burner section 1 is ignited and burned by an igniter 4 provided nearby. At the same time, the motor 11 installed at the rear of the outer box
rotates and air is sent into the wind cylinder 9 and the cold air passage 13. The combustion gas in the burner section 1 passes through the combustion tube 5 and the duct middle plate 1

ちダンパー14は閉成状態になるよう設定されている。After a while after the appliance ignites and burns, the temperature of the combustion tube 5, the duct middle plate 12, and the lower plate 6 becomes high, and the temperature of the warm air blown out from the hot air outlet 13b of the front plate becomes high. When this hot air reaches a certain temperature or higher, the thermistor 19 senses this, the comparator 20 turns ON, and at the same time the transistor 21 turns ON. As a result, current flows through the relay 22, turning on the relay contact, rotating the step motor 15, rotating the damper 14 directly connected to the step motor 15, and opening the cold air outlet 13a. When the cold air outlet 13a is opened, a part of the air sent from the 7-ring 10 reaches the duct middle plate 12.
The cold air is blown into the room through a cold air passage 13 formed by the duct top plate 9. When the appliance is switched off, the step motor 15 reverses to its original position and closes the damper 14. That is, the damper 14 is set to be in the closed state.

する。FIG. 4 is a circuit diagram showing a second embodiment of the present invention. A timer 27 is provided in place of the temperature detection method of the first embodiment, and when a certain period of time elapses after the appliance is turned on, a timer contact 28 connected in series to the step motor 15 turns the step motor 15. The damper 14 directly connected to the step motor 15 is rotated to open the cold air passage 13, thereby eliminating the feeling of cold air at the time of startup.
