BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifying device with a humidifier that can purify and humidify indoor air.

0002

2. Description of the Related Art An air cleaning device will be described with reference to FIGS. 6 to 8. FIG. 6 is a conceptual diagram of a conventional air cleaning device. In FIG. 6, the air purifying device includes a discharge electrode 21, a dust collection electrode 22, a deodorizing filter 23, and a sirocco fan 24. The discharge electrode 21 is connected to the (+) side of the power source, and the discharge electrode 21
A dust collection electrode 22 facing the and connected to the (-) ground side
is provided. A non-woven fabric (not shown) is formed around the dust collection electrode 22 .

Further, the dust collecting electrode 22 has a deodorizing filter 2 made of sponge-like activated carbon, as shown in FIG.
It is combined with 3. And sirocco fan 2
4 rotates, the indoor air is transferred to the discharge electrode 21.
and the dust collecting electrode 22. When the dust particles contained in the air pass through the discharge electrode 21, they are charged (+) and adsorbed to the dust collection electrode 22, which is the (-) side electrode. Furthermore, the odor contained in the air is removed when the air passes through the deodorizing filter 23.

FIG. 7 is a conceptual diagram of another conventional air cleaning device. The conventional example shown in FIG. 7 is different in the dust collecting electrode. That is, the dust collecting electrode 22' is made by packing activated carbon into a nonwoven fabric formed around the dust collecting electrode 22', and integrating the dust collecting electrode 22 and the deodorizing filter 23 shown in FIG. 6. However, a dust collecting electrode using nonwoven fabric or sponge-like activated carbon requires the use of a sirocco fan 24 in order to improve air circulation within the air purifier. Further, in order to obtain the same air volume using the sirocco fan 24, it becomes larger compared to using an axial fan or a cross flow fan.

FIG. 8 is a conceptual diagram of an air cleaning device that eliminates the drawbacks of the conventional example. The conventional example shown in FIG. 8 and the above-mentioned FIG. 6
Or, the difference from the conventional example shown in FIG.
It is located at the points placed on both sides of 7. By adopting such a honeycomb configuration, the sirocco fan 24 can be omitted.

[0006]

However, as shown in FIG. 8, since the dust collecting electrode 25 and the deodorizing filter 26 are formed into a honeycomb shape, air circulation is good and pressure loss is small. Therefore, although it is possible to use the axial fan 27, it is difficult to provide sufficient surface area to the activated carbon, and in order to obtain sufficient deodorizing ability, the length in the air flow direction must be increased. In addition, deodorizing filters using activated carbon require frequent replacement because the activated carbon changes significantly over time.

Furthermore, on the Pacific side of Japan, there is a lot of dust due to abnormally dry winters. During this period, car drivers, especially those driving long-distance trucks, may experience dry throat and eye strain and pain due to dryness. Additionally, the air inside a car is easily polluted by cigarette smoke. Therefore, there has been a demand for an air purifier that combines an air purifier and a humidifier, but since the dust collection electrode, water tank, and humidifying unit take up a lot of space, an air purifier with a humidifier has not been realized. There wasn't.

The present invention is intended to solve the above-mentioned problems, and is an air purifier with a humidifier that integrates an air purifier and a humidifier, and that has a devised arrangement of the humidifier within the air purifier. The purpose is to provide equipment.

[0009]

[Means for Solving the Problems] In order to achieve the above object, the air purifying device with a humidifier of the present invention has a dust collection section consisting of a dust collection electrode and a discharge electrode, and a dust collection section that cannot remove dust. A filter part that can remove dust and odors,
a humidifying section that generates steam and sends it to the outside through a steam delivery pipe; and a humidifying section that guides surrounding air from the dust collecting section to the outside through a filter section and sends water vapor in the humidification section to the outside through the steam delivery pipe. It consists of a blower section that can be used.

0010

[Function] The steam delivery pipe provided in the humidifier of the present invention is designed such that a portion of the air from the ventilation section flows out toward the humidifier from the filter section so that the steam coming out of the humidifier can be easily sent out. A humidifier air guide can also be provided. In the filter section, dust not removed by the dust collection section is removed from the air after the dust collection electrode has collected the dust, and odor is also removed. Further, the steam generated in the humidifying section is sent out from the humidifying section through a steam delivery pipe. Furthermore, even if the length of the dust collecting section and the filter section becomes long, the space is convenient for arranging the water tank of the humidifier and the humidifying unit.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An air purifying device with a humidifier according to the present invention will be explained with reference to FIGS. 1 to 5. FIG. 1 is a perspective view of an air purifying device with a humidifier according to the present invention. FIG. 2 is a sectional view of FIG. 1 according to the present invention viewed from above. FIG. 3 is a sectional view taken along line AA' in FIG. Figure 4 shows C- in Figure 2.
FIG. 4 is a sectional view of another embodiment as seen from C'. FIG. 5 is a conceptual diagram of the air purifying device portion of the air purifying device with a humidifier according to the present invention.

Note that FIGS. 1 and 5, FIGS. 2 and 3
In order to make the diagram easier to draw, the direction of air flow is shown opposite to the left and right. In the figure, a pre-filter 1 is the first place through which dirty air passes after entering the air purifying device 10 with a humidifier, and removes large dust particles. As shown in FIG. 5, the discharge electrode 2 is connected to the (-)
It is connected to the side terminal, and generates a large amount of ozone by negative discharge, and when the dust particles contained in the air pass through the discharge electrode 2, they are charged (-). Then, the dust particles charged on the (-) side are adsorbed to the dust collection electrode 3, which is provided opposite the discharge electrode 2 and is grounded as the (+) side electrode. When the clean air from which dust has been removed is passed through a deodorizing filter 5 by a fan 4, for example, an axial fan 4' (see FIG. 5), odors are removed there.

[0013] Thereafter, the air from which dust and odors have been removed is
It is sent out to the outside of the air purifying device 10 with a humidifier. Further, in the discharge electrode 2, a large amount of ozone is generated when the discharge occurs. Ozone has strong oxidizing power, so it oxidizes odor molecules and turns them into odorless molecules. The remaining ozone can be decomposed by the ozone decomposition honeycomb 5' to which an ozone decomposition catalyst is attached. The ozone decomposition honeycomb 5' to which such an ozone decomposition catalyst is attached is stronger than a filter using activated carbon, and there is no deterioration in performance.

The humidifier includes a humidifying unit 8 that generates steam using heat or ultrasonic vibration, and a humidifying unit 8 that generates steam by using heat or ultrasonic vibration.
It consists of a water tank 11 (part of which is omitted in the perspective view of FIG. 1) connected to the humidifying unit 8, and a steam delivery pipe 9' for guiding the steam generated by the humidifying unit 8 to the outside. The humidifier air guide pipe 9 is connected from a part of the deodorizing filter 5 to a steam delivery pipe 9' of the humidifying unit 8. Since the air flow by the fan 4 is from right to left in FIGS. 2 and 3, this flow drives the steam generated in the humidifying unit 8 upwards and discharges it to the outside through the steam delivery pipe 9'.

Furthermore, as shown in FIG. 4, the steam delivery pipe 9' can be made double so that the air from the fan 4 is sent from the bottom to the top. Therefore, a special fan is not required as a humidifier. Furthermore, the control unit 7 not only controls the high-voltage power supply 6 and the fan 4, but also includes a humidity sensor that detects indoor humidity, and can control the steam generated in the humidification unit 8. In addition, although the axial fan was explained as an example, it is also possible to use a sirocco fan or a cross flow fan.

[0016]

According to the present invention, the steam generated in the humidifier is sent out, so the blower used in the air purifier can be used as a humidifier. Furthermore, since it is an air purifying device with a humidifier, it is effective in dry, narrow rooms where the air is easily contaminated.
