Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling fan mounted on a ceiling for circulating indoor air, and more particularly to a ceiling fan with an air purifier.

[0002]

2. Description of the Related Art A ceiling fan is used alone or in combination with a lighting device to circulate indoor air while maintaining a decorative function, so that cool air for cooling or warm air for heating can be supplied to a room. And contribute to increase the cooling efficiency and heating efficiency. Since this type of ceiling fan has a strong interior element, it is often mounted on a relatively prominent place in a room, for example, on a central ceiling.

[0003]

However, since the above-described conventional ceiling fan merely circulates indoor air, if dust, dust, smoke of cigarettes, etc. are floating in the air, these are removed. Since it is diffused in the room, and there is no ventilation function, there is a problem that it causes sore throat, cough, sputum and the like.

The present invention has been made in view of the above points, and effectively removes dust, dust, smoke of cigarettes, etc. while maintaining the original function of a ceiling fan capable of improving cooling efficiency and heating efficiency. It is an object of the present invention to provide a ceiling fan with an air purifier that can perform the above operation.

[0005]

SUMMARY OF THE INVENTION The present invention provides a rotating drive means mounted on a ceiling for rotating a plurality of blades,
It is characterized by comprising a plurality of blades attached to the rotation driving means, and an air purifier attached to the rotation driving means to generate negative ions.

According to the present invention, since an air purifier for generating negative ions is attached to the rotary driving means of the blade constituting the ceiling fan, the negative ions are diffused into the room by the ceiling fan, and the negative ions are diffused into the room. It effectively captures dust, dust, smoke, pollen, smell and the like in the room and moves to the floor. As a result,
Cooling and heating efficiency improvement function by ceiling fan,
The air purifying function can be satisfied at the same time, and an extremely comfortable living space can be provided.

[0007] The air purifier includes a conductive cylindrical electrode having one as an air inlet and the other as an air outlet, and a needle electrode facing the air inlet of the cylindrical electrode. And a high voltage generating means for applying a high voltage to both electrodes so that the cylindrical electrode is positive and the needle electrode is negative, and corona discharge generated by application of a high voltage to both electrodes. It is possible to use an electrode that generates an air flow containing negative ions from the air inlet to the outlet of the cylindrical electrode by Coulomb force.

The use of such an air purifier has the advantage that no noise is generated because a motor fan or the like is not used to generate an air flow containing negative ions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a ceiling fan with an air purifier according to one embodiment of the present invention. An arm 3 is suspended from the ceiling 1 via a flange 2, and a ceiling fan body 4 serving as a rotation driving means is attached to a tip of the arm 3. The ceiling fan body 4 accommodates a rotation drive unit (not shown) therein, and the base ends of the four blade frames 5 are coupled to the rotation drive unit. The front end side of the blade frame 5 radially protrudes outward from the lower end opening of the ceiling fan main body 4, and the blades 6 are attached to the front end portions, respectively.

An air purifying unit 7 is attached to a lower end of the ceiling fan body 4. As shown in FIG. 2, the air purifying unit 7 houses one or more air purifier main bodies 11 therein, and generates a negative ion air flow generated by the air purifying main body 11 into an ion discharge port 13 on a lower side of the cover 12. From the outside. Cover 1
In addition to the above, the ceiling fan body 4 at the top of 2,
A wind direction changeover switch 14, an air volume adjustment switch 15, and a main switch 16 are provided, and a neon lamp 17 and the like are attached to the cover 12.

As shown in a cross section in FIG. 2, the air purifier main body 11 has a cylindrical electrode 21 having a central axis extending vertically.
And a needle-like electrode 22 arranged so as to face the upper end opening of the cylindrical electrode 21, and a high-voltage generator 23 for applying a high voltage between these two electrodes. Both the cylindrical electrode 21 and the needle electrode 22 are formed of a titanium alloy such as titanium oxide, thereby ensuring a semi-permanent life. Although only one air purifier main body 11 is shown here, actually, about four air purifier main bodies 11 are attached to the air purifying unit 7 so as to correspond to the respective ion emission ports 13. Have been.

Now, DC 7,000-8.0 between both electrodes.
When a high voltage of about 00 V is applied, the cylindrical electrode 21
Corona discharge occurs between the upper edge of the (+) and the tip of the needle-shaped electrode 22 (−), and a collision between electrons generates a wind pressure of about 2.0 m / sec. At the same time, negative ions are generated (approximately 2 million / cc) by the photocatalytic phenomenon caused by the titanium oxide of the electrode material, and the negative ions are emitted to the outside through the ion emission port 13.

Outside, since the ceiling fan is activated, the negative ion flow discharged to the outside is evenly diffused to every corner of the room. The diffused negative ions effectively collect pollen, mite dust, cigarette smoke, etc. up to 2.0-0.001 μm, which are harmful to the human body.
It is also effective in deodorizing garbage and new building materials. Since the air purifier body 11 does not use a filter, maintenance such as replacement is not required.

FIG. 3 is a perspective view showing an example in which a globe lamp 8 is added as a lighting device to the ceiling fan with an air purifier described above. As in this example, by combining a ceiling fan and a lighting device, it is possible to further enhance interior characteristics and functionality.

FIG. 4 is a diagram for explaining the flow of air during cooling and heating of the ceiling fan of the present invention.
At the time of cooling, as shown in FIG. 11A, the air is blown from top to bottom so that the cold air accumulated below does not directly hit the person under the ceiling fan. At the same time, the negative ions come into direct contact with the dust accumulated under the room, thereby realizing an effective dust collecting function. In addition, during heating, as shown in FIG. 11B, the air is sent from below to above so that the warm air accumulated above does not directly hit a person under the ceiling fan. At the same time, the negative ions come into direct contact with the dust and smoke accumulated on the room, thus realizing an effective dust collecting function.

[0016]

As described above, according to the present invention, since the air purifier for generating negative ions is attached to the rotary driving means of the blade constituting the ceiling fan, the negative ions are introduced into the room by the ceiling fan. Is diffused, and this negative ion becomes dust, dust,
By effectively capturing smoke, pollen, smell, etc., it is possible to simultaneously satisfy the cooling and heating efficiency improving function of the ceiling fan and the air purifying function, thereby providing an extremely comfortable living space. This has the effect.
