Description

Double fan and electric heater {Electric fan and heater formed two head set}

The present invention relates to a double head fan and an electric heater configured to allow several people to simultaneously satisfy the effects of the fan or the electric heater in the fan and the electric heater, and to send wind or heater heat in different directions to one body. The two-head fan and electric heater having a fan or a heater in pairs to be configured.

Looking at the type of conventional electric fan and electric heater, since the direction of the blade rotated by one motor in one body is directed only in one direction, only a person located in the direction of the blade for blowing air can get cool wind. have. However, in a space where several people are inevitably, the wind blades are forced to 'rotate' to allow multiple people to get the wind together, but most people are in a position above 90 degrees because the rotation angle is limited to within 90 degrees. Will not be affected. In order to obtain the wind again after being rotated once, a disadvantage occurs such that the wind can be obtained after 10 seconds by the cycle of the blowing direction by the repeating blade for blowing. This deepens the thirst for heat rather than feeling cool.

This drawback is the same drawback as described above not only in the fan of the rotary blow blade type, but also in the upright fan and the radial electric heater.

In order to compensate for this disadvantage, Utility Model Application No. 20-1996-032785 constitutes a motor at the upper center of one body and blows wings in the opposite direction on the same axis so that wind is blown outward on both ends of the rotating shaft of the motor. Were respectively constructed. In the conventional double fan configured as described above, since the wind direction is always configured to be blown in the opposite direction, the wind is drawn in only between the middles of the two wing blades in the wind blowing direction. That is, in tug of war, one string is pulled from both sides. In order to increase the intensity of the wind blown to a person by the blower wing, the wind flowing into the blower wing should be smoothly drawn in. However, in the conventional double fan, the wind blower always faces the other side, so It is divided into two sides and blows. Although the size and capacity of the blower motor may be increased even in this case, the greater the rotational force of the blower, the greater the force to divide the wind of one place in the same direction in the opposite direction, the resonance will eventually occur, The larger the value is, the greater the noise caused by the resonance phenomenon, which in turn causes stress to the user.

More specifically, as shown in FIG. 6, the directions of the winds generated by the fan-1 20-1 and the fan-2 20-2 are opposite to each other. When the wind is blown opposite to each other 180 degrees, the air at the ① position is divided into two sides, one side to the ② side, the rest of the air flows in the ⑦ direction, which is 180 degrees to the wind. The air moved in the ② direction is divided into ③ side and ⑪ side, and the ① side air is divided into 4 minutes by the fan-1 (20-1) and fan-2 (20-2) to flow through a certain space. The amount or intensity of the flow will decrease. In particular, since the wind directions of the fan-1 (20-1) and fan-2 (20-2) on both sides are 180 degrees from each other, the wind intensity may be increased in the ② and ⑦ by the division of air by ①. Due to the division of the amount of air, it is slightly weakened at ③⑥⑧⑪, and the air flow intensity is weakened even at ④⑤⑨⑩.

The wind, that is, the air flow, is caused by the movement of high atmospheric pressure air into the region of low atmospheric pressure, and the wind, that is, the air flow is generated by the difference in the density of air in a predetermined space. In the ⓐⓑⓒⓓ position, the magnitude of the force that the air flow is divided or combined is equally generated at both sides, so that the air flow is weakly generated, so that it is almost impossible to feel cool in this region. In order to compensate for this disadvantage, it is necessary to use a motor with a large capacity. However, the noise causes a disadvantage in that it cannot be used indoors such as an office.

In the conventional twin fan configured as described above, looking at the flow of the entire air in the predetermined space, the air is divided into two parts and blown around the motor of the double fan. Thus, it is not easy to make air feel good by dividing and blowing air in a certain space, and to overcome this, a disadvantage of having to use a motor with a very large capacity appears.

The present invention relates to a double head fan and an electric heater configured to overcome the above disadvantages, comprising a fan or a heat radiating unit for radiating heat in one body, two wind direction or heat radiating direction It is configured not to be opposite to each other, and is configured to supply warmer air to cooler air than one having a blower wing, and in a variety of directions in an electric heater. It is an object of the present invention to configure so that the overall wind or heat in a predetermined space is circulated and blown.

When described in detail with reference to the accompanying drawings, preferred embodiments to achieve the object of the present invention configured as described above are as follows.

As a first embodiment, as shown in Figures 1 and 2, relates to a two-head fan constituting a general fan, the upper plate (top) on the upper side of the column (11) configured to stand upright on one side of the body (10) supported on the floor ( 12, and the shaft-1 (22-1) and the shaft-2 (22-2) which become the pillars of the rotating shaft of the fan 20-1, 20-2 rotated to both sides of the upper plate 12. It was configured to stand upright. A driving motor-1 21-1 and a motor for driving the fans 20-1 and 20-2 above the two shafts 22-1 and 22-2. 2 (21-2) are configured, respectively, fan-1 (20-1) and fan-2 (20-2) so as to be interlocked with the axes of each motor-1 (21-1) and motor (21-2). Were respectively constructed. And drive each fan 20-1, 20-2, rotate each fan 20-1, 20-2 with respect to the top plate 12, and the top plate 12 also has a body. The operation plate 13 for operating so as to rotate with respect to (10) is configured on one side of the body (10).

At this time, the angle of the direction of the wind caused by both the fan-1 (20-1), fan-2 (20-2) is configured to be larger than 0 degrees and smaller than 180 degrees.

As illustrated in FIG. 5, the air located at ⑥ by the fan-1 (20-1) has a flow circulating back from ⑦-①-② to ⑥ and the fan-2. By (20-2), the air located at ⑧ has a flow that circulates from ⑨-⑩-④ back to ⑧. In particular, the direction of the wind flowing by both fans-1 (20-1) and fans-2 (20-2) is greater than 0 degrees and less than 180 degrees, so that the air located between ⑥ and ⑧ Because of the instantaneous low pressure generated by the flow, the air at the ③⑤ position, which was relatively high, is moved to the positions ⑥ and ⑧, respectively. The air in the position also flows from ⓔ to ⓕ, and eventually almost all air in a certain space flows.

An example of this is that if the mouth of the rubber pack (specifically, the balloon) has no elasticity and the mouth is closed and the wind is blown into the mouth, only air limited to the individual lung capacity will be introduced. If you take your mouth and blow air to maintain a certain distance (about 5 to 10 cm) from the inlet, the air around the flowing air as well as the air due to the user's lung capacity flows into the rubber pack together due to the physical properties of the fluid flow. As a result, much more air is introduced. In general, when the air inflow by the spirometry of about 20 times blows the wind while maintaining a constant gap from the inlet, the air may be filled only once or twice.

As another example, if the fan is installed in accordance with the wall to configure the air to be discharged only into the frame formed in the fan, only a limited amount of air is discharged, but a predetermined distance from the holed wall to match the fan size When the fan is driven after the fan is installed inward to the inside of the room, the fan flows not only the amount of air by the fan but also the surrounding air of the flowing air by the flow of the fluid, and thus a lot of air is discharged in a faster time. You can see the phenomenon.

In view of the properties of such a fluid, the preferred angle of the wind direction by both fans is about 45 degrees. This is because the initial strong wind by both fans has the overall flow direction flowing from ⓔ to ⓕ. At this time, the wind direction by the fan is 22.5 degrees, which is 45/2, with respect to the center consisting of ⓕ in ⓔ. In other words, the initial force of the wind acts the initial force of the air flow in the direction of 22.5 degrees with respect to the overall air flow direction.

In the present invention configured at this time, each of the fan-1 (20-1) and the fan-2 (20-) using the shaft-1 (22-1) and the shaft-2 (22-2) on both sides of the upper plate as the rotating pillars. 2) is rotated, and also the top plate 12 is configured to rotate with the center of rotation of the column 11 configured in the body 10, so that even in any position in a certain space is configured to feel the coolness by the wind evenly. .

As a second embodiment of the present invention, as shown in Figures 3 and 4, in the air-conditioning fan, the upper plate 12 to the upper side of the column 11 configured to stand upright on one side of the base body 10 Air conditioner fan-1 (20-3) and fan- on top of shaft-1 (22-1) and shaft-2 (22-2) each configured to be erected at both ends of the upper plate 12, respectively. 2 (20-4), respectively, and the air conditioner type fan-1 (20-3) and the fan-2 (20-4) are shaft-1 (22-), respectively, as in the first embodiment. 1), it was configured to rotate around the axis-2 (22-2), and also the top plate 12 was also configured to rotate about the column 11 is formed upright on one side of the tum body (10).

In another embodiment, in the first embodiment, an electric heater is formed in a double head type radial heat radiating unit that generates warm heat by using a blowing fan. Radiating heat radiating unit for radiating heat was rotated about each axis configured on both sides of the top plate, and also the top plate is rotated about the body, so that more people feel warm warmth in the cold season.

The present invention relates to a twin head fan and an electric heater, comprising two thermal radiators for generating a fan or heat radiating wind in one body, so that the wind direction or heat radiating direction is not opposite to each other, one It is configured to supply warmer air in a variety of different directions in the electric heater, especially in the electric heater, so that the wind direction or the heat radiation direction is not opposite to each other. The heat is circulated and blown to provide the effect that more people can feel cool wind or warm warmth.
