In particular, the second opening 15 side in which the hand is put into the groove 12 is constituted by the opening slope 19 having a gentle slope, so that an effect of making the hand easier to obtain can be obtained.

  Further, as shown in FIG. 2, the air conditioner 100 according to the first embodiment is provided with the step portion 17 on the lower side of the portion where the handle portion 13 and the louver 16 are in contact with each other, so that the louver 16 is closed. There is an advantage that it becomes easier to grip when gripping the handle portion 13 in a state.

  Further, as shown in FIG. 9, the air conditioner 100 according to the first embodiment is easy to grip because the handle portion 13 appears when the louver 16 is opened, and can firmly grip the handle portion 13 from either direction.

  Next, the configuration of the air conditioner 100 according to the second embodiment will be described with reference to FIGS. 2, 8, and 9. In the air conditioner 100 shown in FIG. 2, an air passage 24 that connects the suction port 21 to the blowout port 22 is formed inside the housing 10.

  The blower 20 provided in the middle of the air passage 24 includes a fan motor 20a and a fan 20b such as a sirocco fan. When the fan motor 20a rotates the fan 20b, external air is sucked into the device from the suction port 21. (See white arrow A).

  The introduced air is dedusted while passing through the pre-filter 70 and the dust collection filter 71 used in the existing deodorizer. A deodorizing unit 40 is disposed on the leeward side of the dust collection filter 71. The deodorizing unit 40 performs a deodorizing process using the catalyst filter 41 and periodically heats the catalyst filter 41 by the heater unit 46, thereby promoting the decomposition of odorous components adhering to the catalyst, It can be played repeatedly. The deodorizing unit 40 is configured by arranging a pair of breathable plate-like heat insulating materials 42 so as to sandwich the catalyst filter 41 and the heater unit 46 from both sides.

  On the further leeward side of the deodorizing unit 40, a humidifying unit 30 including a vaporizing filter that gives humidity to the air passing through in a wet state by absorbing water is disposed. The air humidified by the humidification unit 30 is sent through the air passage 24 in the directions of the white arrows B and C by the fan 20b of the blower 20 (see FIGS. 8 and 9), and further the white arrows D, E, F, or As indicated by white arrows G and H, the air is discharged from the first opening 14 or the second opening 15 through the air outlet 22 and the low-concentration ozone air outlet 78.

  Moreover, the air conditioner 100 of Example 2 is provided with the ozone generation unit 73 as shown in FIG.2, FIG8 and FIG.9. The air flowing through the air passage 24 by the blower 20 branches from the white arrow B to the white arrow C and flows into the ozone generation unit 73. When the air taken into the ozone generating unit 73 is irradiated with a UV (ultraviolet) lamp 74 such as a mercury lamp, ozone is generated. In addition to the vaporization filter of the humidification unit 30, this ozone can be sterilized and deodorized in the air. Residual ozone generated in the ozone generation unit 73 is decomposed through an ozone decomposition catalyst 77 such as titanium oxide and discharged outside from the low-concentration ozone outlet 78 (see the white arrow E).

  Further, in the air conditioner 100 according to the second embodiment, as shown in FIGS. 2, 8, and 9, an ionizer 79 that generates negative ions is disposed in the air passage 24 here. The ionizer 79 includes a needle-like electrode. When a high voltage of, for example, several kV is applied to the electrode, corona discharge is generated at the tip of the electrode, and negative ions and ozone are generated. Negative ions generated from the ionizer 79 react with ozone generated from the ionizer 79 and the ozone generation unit 73 to generate OH radicals having a strong oxidizing power.

  In the air conditioner 100 of the second embodiment, as in the first embodiment, when the air deodorized by the deodorizing unit 40 is blown out from the outlet 22 through the air passage 24, the louver 16 shown in FIG. Is in the fully closed state, flows toward the second opening 15 along the louver 16, and is once pushed down by the stepped portion 17, and then a series of air blown out from the second opening 15 through the groove 12. A flow is formed. Since the ionizer 79 is disposed in the air passage 24, this air becomes deodorized air containing negative ions. Further, when the ozone generated in the ozone generation unit 73 is discharged from the low-concentration ozone outlet 78 (see the white arrow E), the flow of the deodorized air (see the white arrow D) described above. The second opening 15 is blown out in the horizontal direction. Here, the low-concentration ozone outlet 78 has a width from the position adjacent to the outlet 22 to the vicinity of the second opening 15 as shown in FIG. For this reason, the ozone discharged from the low-concentration ozone outlet 78 closer to the outlet 22 than the position of the handle portion 13 in FIG. 8 is taken into the flow of deodorized air blown out from the outlet 22 (outlined). Sent to the second opening 15. Further, since ozone released from the low-concentration ozone outlet 78 provided near the second opening 15 from the bottom of the handle 13 in FIG. 8 is close to the second opening 15, it can be released upward as it is. There is sex. However, the ozone discharged from the low-concentration ozone outlet 78 has a flow of deodorized air that is blown out from the outlet 22 and is thus taken in and is taken in horizontally from the second opening 15. Blown out (see white arrows D, E, F).

  As described above, when the louver 16 is fully closed, the air conditioner 100 according to the second embodiment can blow out deodorized air containing negative ions and low-concentration ozone to the front side (horizontal direction) of the air conditioner. Therefore, the ion concentration and ozone concentration near the floor surface can be increased, and mites, pollen, pet-derived allergens and the like that settle on the floor can be effectively inactivated.

  Moreover, in the air conditioner 100 of Example 2, when the louver 16 shown in FIG. 9 is in a fully open state, the air deodorized by the deodorizing unit 40 passes through the air passage 24 and passes through the air outlet 22 to the first opening 14. And the air containing ozone generated by the ozone generation unit 73 passes through the low-concentration ozone outlet 78 and passes through the first opening 14 and the second opening 15. Therefore, the deodorized air containing negative ions or ozone can be blown upward as well.

  Next, in the air conditioner 100 according to the third embodiment, as illustrated in FIG. 10 as viewed from the direction of the arrow X in FIG. Tapered portions 13a and 13b are formed so as to straddle the top and gradually reduce the thickness of the handle portion 13 from both sides of the groove portion 12 toward the center portion. The taper portions 13a and 13b can be formed by changing the inclination of the taper and the shape of the taper, whereby the length of the width I of the handle portion of the handle portion 13 can be changed. The length I of the handle portion is assumed to be held by a human hand. In the third embodiment, the width I of the handle portion of the handle portion 13 is 140 mm, but this is an example and the present invention is not limited to this.

  Moreover, the taper parts 13a and 13b of the handle part 13 can be adjusted to narrow or widen the opening area of the second opening part 15 shown in FIG. 2 by changing the shape thereof. When the opening area of the second opening 15 is narrowed, the wind speed blown from the outlet 22 increases, and when the opening area is widened, the wind speed blown from the outlet 22 can be lowered. In particular, in the above embodiment, as shown in FIGS. 8 and 9, the opening degree of the first opening 14 can be changed by changing the opening angle of the louver 16, and how the tapered portions 13 a and 13 b are changed. The opening area of the second opening 15 can be changed depending on the shape. Thus, since the ratio of the opening area of the 1st opening part 14 and the 2nd opening part 15 can be adjusted suitably, it is optimal according to the capability etc. of the fan motor 20a, the power-saving, the object which cleans air, etc. Design can be performed. Furthermore, it is very convenient for the user to change the blowing direction of deodorized air containing negative ions or ozone by the louver 16.

  In the above embodiment, as shown in FIG. 1, the louver 16 has been described as an example of a single plate. However, the present invention is not limited to this, and a plurality of parallel plates that can rotate in conjunction with each other are used. The louver may be configured so that the wind direction can be varied not only in the vertical direction but also in the horizontal direction. Thereby, the unevenness of the blown wind direction can be reduced, and a more preferable effect can be obtained in terms of wind direction control.

  In addition, in the said Examples 1-3, although demonstrated as the general air conditioner 100, specifically, it can apply suitably to an air cleaner, a deodorizing machine, a humidifier, a dehumidifier, etc. .

  As described above, the air conditioner according to the present invention is useful for an air conditioner that can be stably carried with one hand without increasing the size of the main body, and in particular, from the air outlet provided on the upper surface of the main body. It is suitable for an air conditioner that can change the blowing direction of the blown air.
