本発明は、夏季においては扇風機として使用し
冬季においては電気温風機として使用する扇風機
兼用温風器に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fan/air warmer that is used as an electric fan in summer and as an electric hot air fan in winter.
従来の扇風機兼用温風機器は、いずれも両者の
機能を十分満足することができず、しかも、構造
が複雑であり、しかも取扱性が悪く、実用的でな
かつた。これは扇風機と温風機とでは風速及び風
量においては本質的に相反する特性をもつてい
る。 None of the conventional electric fan/warm air appliances can fully satisfy both functions, and furthermore, they have complicated structures and are difficult to handle, making them impractical. This is because electric fans and hot air blowers have essentially contradictory characteristics in terms of wind speed and air volume.
まず扇風機として要求されるものはJIS規格に
よると口径20cmのフアンでは60cm前方で風速約２
m/sec以上、風量12.5m3/min以上の強風、大風
量が要求されるのに対し、温風機としての機能を
考えると、冷風を感じず、しかも適度の風速が必
要である。即ち、50〜100℃の温風で吐出口にお
ける風速は１〜２m/sec程度が経験的に適当であ
る。ところが一般家庭用温風機は1.5kW以下の熱
量が普通であるから、吐出風量は吐出口にてせい
ぜい１〜２m3/min、即ち扇風機の1/10以下に落
さないと冷風になつてしまう。しかし、これだけ
大きな風量調節はモーターの回転数の調節だけで
はかなり困難であるのみならず、温風機吐出口の
大きさも扇風機の場合と同一では吐出風速が低す
ぎて風を感じなくなつてしまうので、吐出口に開
閉自在のダンパーを設けて風を集める等の機械的
な操作も必要になる。 First of all, according to the JIS standard, a fan with a diameter of 20 cm is required to have a wind speed of approximately 2 at a distance of 60 cm in front of the fan.
Strong winds of m/sec or more and air volume of 12.5 m 3 /min or more and a large air volume are required, but considering the function as a hot air fan, it is necessary to not feel cold air and to have a moderate wind speed. That is, it is empirically appropriate that the wind speed at the discharge port is about 1 to 2 m/sec for hot air of 50 to 100°C. However, since the heat capacity of a general household hot air fan is usually less than 1.5kW, the air volume must be reduced to 1 to 2 m 3 /min at the outlet, or less than 1/10 of that of an electric fan, or the air will turn into cold air. . However, adjusting such a large air volume is not only difficult by simply adjusting the motor's rotation speed, but if the warm air outlet is the same size as a fan, the discharge speed will be too low and you will not feel the wind. , Mechanical operations such as installing a damper that can be opened and closed at the discharge port to collect the wind are also required.
例えば、従来例を示す実公昭48−23143号公報
及び実公昭48−36433号公報に記載の如く、従来
の実施例で説明すると、第１図に示すようにほぼ

出口２前面に可動自在に吐出口風量調節用のダン
パー６が設けてある。 For example, as described in Japanese Utility Model Publication No. 48-23143 and Japanese Utility Model Publication No. 48-36433, which show conventional examples, in the conventional example, as shown in FIG. air intake port 1
A fan motor 4 and a heat generating part 5 are provided in a case 3 having a discharge port 2 and a fan motor 4 on the front side of the discharge port 2, and a damper 6 for adjusting the air volume of the discharge port is movably provided in front of the discharge port 2.
扇風機として使うときは、発熱部５を通電せず
にダンパー６を開放し、温風機のときは発熱部５
を通電しダンパー６を調節して吐出口２を絞り適
度の風速を風量に低下させる。尚、フアンモータ
４の回転方向と回転数は固定式で常に一定のもの
である。 When used as an electric fan, the damper 6 is opened without energizing the heat generating part 5, and when the heat generating part 5 is used as a hot air fan, the heat generating part 5 is turned off.
Electricity is applied, the damper 6 is adjusted, the discharge port 2 is throttled, and the air velocity is reduced to an appropriate air volume. Note that the rotation direction and rotation speed of the fan motor 4 are fixed and always constant.
このような構成では、ダンパー６を調節すると

生が大きくなると共に、扇風のときたとえダンパ
ー６を開放してもダンパー６はフアンモータ４前
面に位置する為、風の抵抗となり、かなりの風力
低下が避けられない。さらに、ダンパー６はフア
ンモーター４の振動により振動音が発する可能性
がある。 In such a configuration, not only is it troublesome to adjust the damper 6, but also the damper 6 generates a large amount of noise due to air resistance when using a hot air fan. Even when opened, the damper 6 is located in front of the fan motor 4, creating wind resistance, and a considerable drop in wind force is unavoidable. Furthermore, the damper 6 may generate vibration noise due to the vibration of the fan motor 4.
また、発熱部５は熱交換を良くするため、フア
ンの前面や近くに置はなければならないので、移
動式でない限り、扇風機の時に風の抵抗を受け、
大きな風量低下を起すという欠点があつた。 In addition, in order to improve heat exchange, the heat generating part 5 must be placed in front of or near the fan, so unless it is mobile, it will experience wind resistance when used as a fan.
The drawback was that it caused a large decrease in air volume.

を提供するものである。 In order to solve the above-mentioned drawbacks, the present invention provides a fan and a heat generating part inside the case so as to face each other, has an air intake port and cool air discharge port in front of the fan, and has an air intake port and cool air discharge port on the opposite side. An air inlet/warm air outlet with an opening area smaller than the opening area of the cool air outlet is opened, and a heat generating part is interposed between the air intake/warm air outlet and the fan, so that the fan An electric fan equipped with a fan motor such that when the fan rotates, it emits a large amount of cool air from the air intake port and cool air outlet, and when the fan rotates in reverse, it releases a small amount of warm air from the air intake port and hot air outlet. It also provides hot air equipment.

である。 With the above-mentioned configuration, the functions of both an electric fan and a hot air fan can be fully satisfied by using a fan motor that can rotate forward or reverse simply by switching a switch without mechanical operation of a damper or the like. be.
以下、本発明の一実施例を図により説明する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

が電気的な切替スイツチ（図示していない）で切
替可能になつている。 The configuration of the embodiment is as shown in FIG. 2, in which a fan motor 7 is provided in the case 3 that can change the wind direction by forward or reverse rotation, etc. An air inlet/cool air outlet 8 and an air inlet/warm air outlet 9 having an opening area smaller than the opening area of the air inlet/cool air outlet 8 are provided, and a heat generating portion 5 is provided within the case 3. The air inlet and hot air outlet 9
and the fan 10.
The fan 10 uses a propeller fan such as that commonly used in electric fans, and the motor 7 uses, for example, a capacitor motor, and can be switched between forward rotation and reverse rotation with an electrical switch (not shown). There is.
前述の構成に於ける動作は、まず、扇風機とし

転方向にフアン１０が回転し、同時に発熱部５に
通電し、温風として適量が通過して、該温風吐出
口９から温風が出る。 The operation in the above-mentioned configuration is that first, when used as an electric fan, the fan 10 rotates in the forward rotation direction;
Air is sucked through the air inlet/warm air outlet 9, and cool air is emitted from the cool air outlet 8. In this case, the heat generating part 5
is not energized. On the other hand, when used as a hot air fan, the fan 10 rotates in the opposite rotation direction, and at the same time, the heat generating section 5 is energized, an appropriate amount of hot air passes through it, and hot air is output from the hot air outlet 9.
次に、第３図は他の実施例である。第２図と異
なる点は、ケースの温風、涼風吐出口８，９以外
に、フアンモーター外周部に通気孔１１を設けた
ことである。 Next, FIG. 3 shows another embodiment. The difference from FIG. 2 is that in addition to the hot air and cool air outlets 8 and 9 of the case, a ventilation hole 11 is provided on the outer periphery of the fan motor.
このようにすると、第３図ａのように、扇風機

強い風を出すことができる。一方では、温風機の
時は第３図ｂのように、フアンによる風は直進す

た実用上不快を感じない程度に押えることは設計
上可能である。 In this way, as shown in FIG. 3a, when using an electric fan, air can also be sucked in through the ventilation hole 11, and even stronger wind can be emitted. On the other hand, when using a hot air fan, as shown in Figure 3b, the air from the fan travels in a straight line, so the amount of air leaking from the ventilation holes 11 is small, and it is possible in design to suppress it to a level that does not cause discomfort. It is.
更に、第４図はさらに他の実施例である。第３
図と異なる点は、さらに外周部の通気孔１１に風
向板１２を設けた。このようにすると温風機の
時、直接に風向板１２に風が当り、ケース３外に
冷風の漏れる量をさらに減ずることができる。 Furthermore, FIG. 4 shows still another embodiment. Third
The difference from the figure is that a wind direction plate 12 is further provided in the ventilation hole 11 on the outer periphery. In this way, when the hot air fan is used, the wind directly hits the wind direction plate 12, and the amount of cold air leaking out of the case 3 can be further reduced.
従つてつぎのような作用効果がある。 Therefore, it has the following effects.
一般に使われてるプロペラフアンは正回転を逆

た、一方では該温風吐出口９を適度に絞つて開口
状態にしてあるので、温風機として使う時は適当
な風速、及び風量が得られる。 The blowing efficiency of commonly used propeller fans is quite different between forward rotation and reverse rotation, and simply rotating the propeller in the opposite direction significantly reduces the amount of warm air blown. Also,
Since the cool air outlet 8 is left wide open, when a fan is used, there is no wind resistance at the front cool air outlet 8, so a strong cool breeze can be obtained. At the same time, since the heat generating part 5 can be provided near the hot air outlet 9 away from the fan motor 7, the resistance of the wind against the fan 10 can be reduced, so that a strong enough wind can be obtained as an electric fan. On the other hand, since the warm air discharge port 9 is opened by appropriately constricting it, an appropriate wind speed and volume can be obtained when used as a hot air fan.

等有益なものである。 As described above, the present invention provides a fan and a heat generating part facing each other inside the case, has an air intake port and cool air outlet at the front of the fan, and has an air intake port and cool air outlet at the opposite side. An air inlet/cool air outlet having an opening smaller than the opening area is provided, a heat generating part is interposed between the air inlet/warm air outlet and the fan, and when the fan rotates forward, the air inlet/cool air outlet is opened. Equipped with a fan motor that discharges a large amount of cool air from the cooling air outlet and a small amount of hot air from the air intake and hot air outlet when the fan rotates in reverse, By using a reversible fan motor, a fully functional electric fan and warm air fan can be obtained by simply changing the blowing direction, and there is no need for mechanical mechanisms such as dampers that can cause failures. The present invention is advantageous in that it is possible to obtain a warm air fan that also functions as a fan and is easy to handle.
