[0016]
Hereinafter, an embodiment of the present invention will be described in detail.
[0017]
FIG. 1 is an external perspective view when an indoor unit 9 of a separate type air conditioner is installed in a room. FIG. 2 is a plan external view as viewed from the direction A in FIG. 3 is a longitudinal sectional view taken along line BB of FIG. 2, and FIG. 4 is a longitudinal sectional view taken along line CC. It is attached closely to the ceiling in the room and the corner of the two walls, has a first suction grill 10 below, and has a first outlet 11 in the arc. Further, the second suction grille 12 is disposed on the back side of the first suction grille 10 so as to be shared in appearance, and further has a second outlet 13A on the back side. The first outlet 11 is provided with wind direction changing blades 14 along the arc. When the cross flow fan 15 is rotating and performing a blowing action, air is sucked in from the lower first suction grille 10, heat is exchanged via a heat exchanger 16 composed of two parts, and arc-shaped blowing is performed. The air flows to the mouth 11 and acts as a blower. Reference numeral 17 denotes a water tray for treating the condensed water of the heat exchanger, and reference numeral 18 denotes a toy for treating the condensed water of the heat exchanger on the inclined portion and guiding it to the water tray.
[0018]
The first outlet 11 composed of the stabilizer 19 and the rear guider 20 blows out substantially horizontally as shown in FIG. 3 in the cross-section at the center of the arc, and blows downward as shown in FIG. . The portion H in FIG. 3 is completely horizontal, and the portion H gradually recedes from the BB section of the first outlet 11 to the CC section. Further, the outlet is directed downward at a position close to the CC section, and the height of the outlet is kept horizontal by gradually changing three-dimensionally. In such a configuration, the air flowing along the vicinity of the wall faces downward, and the air flowing toward the center of the room faces in the horizontal direction, so that the air flow easily reaches the entire room evenly, and the comfort is improved. . When there is no horizontal portion of the outlet, the same three-dimensional outlet effect can be obtained by gradually changing the inclination of the outlet from the BB section to the CC section and directing the outlet downward.
[0019]
The second blower circuit draws air from the second suction grille 12 with respect to the first blower circuit, and distributes sufficiently dedusted and deodorized air to the rear through a high-performance HEPA filter 21 and a light regeneration adsorption filter 22. The air is blown into the room from the second blowout port 13A through the sirocco fan 23 provided.
[0020]
In the air conditioner according to FIG. 2, the second outlet 13A is arranged on the back side of the second suction grille 12, but the position is inconvenient depending on how the refrigerant pipe is routed from the heat exchanger 16 in the indoor unit main body. There is also. FIG. 5 shows an air conditioner in which the second outlet 13B is provided at another location. In this case, the second outlet 13 </ b> B is provided on the right corresponding to an intermediate position between the first suction grill 10 and the second suction grill 12.
[0021]
FIG. 6 is a longitudinal sectional view taken along line CC of FIG. At this time, the path from the sirocco fan 23 to the second outlet 13B was a flexible pipe 24. This air conditioner is a case where the refrigerant pipe is routed from the heat exchanger 16 to the back corner of the second suction grill 12 from the left side. When the refrigerant pipe is routed from the right side to the back corner of the second suction grille 12, the refrigerant pipe is naturally provided on the left, which is an intermediate position between the first suction grille 10 and the second suction grille 12. This makes it possible to respond to any change in the location where the second outlet 13B is provided. For reference, FIG. 7 is a longitudinal sectional view taken along the line BB of FIG. 2, and the path from the sirocco fan 23 to the second outlet 13B is a flexible pipe 24, which is shown in FIGS. It is possible to cope with such a case.
[0022]
Further, in the present invention, the second blower circuit can be made detachable by integrating it like a unit. As a result, the air conditioner provided in the corner of the room as in the present invention can be made an optional functional component. Furthermore, if the air conditioner provided in a corner of such a room is also installed in another room and has compatibility, the second air blower having an excellent air purifying function for the air conditioner in another room if necessary Only the circuit can be replaced and moved.
[0023]
The light regeneration adsorption filter can be regenerated by sunlight, an ultraviolet lamp or the like by highly dispersing fine particles of anatase-type titanium dioxide with zeolite having a high silica ratio as a main adsorption component. The cycle of the regeneration is not particularly limited, but may be appropriately performed at a level at which the user is not dissatisfied with the adsorption performance. Specifically, about six months is a guide, though it depends on the amount of the adsorbent carried. The high-performance HEPA filter is a general term for a filter having an ability to remove 99.97% of 0.3 μm particles at 25 mmAq or less.
[0024]
Since the circuit that emphasizes the air purifying function is provided as the second blower circuit, it can be operated alone in the air purifying mode even when cooling and heating are not performed.
[0025]
FIG. 12 and FIG. 8 show the temperature distribution in the plane of the room when the conventional air conditioner and the air conditioner of the present invention are arranged at the corners of the room and the heating operation is performed.
[0026]
FIG. 12 shows a temperature distribution of the conventional air conditioner, and the temperature is low near two walls where the air conditioner is in close contact. On the other hand, FIG. 8 shows the temperature distribution when the quarter-arc air conditioner of the present invention is installed. It can be seen that is improved.
[0027]
Although the light regeneration adsorption filter is used in the embodiment, a heat regeneration filter can be used in the present invention. In the heat regeneration, a high-silica adsorbent such as zeolite and a catalytic metal such as Pt and Pd are dispersed and supported, and heated to about 300 ° C., whereby combustion oxidative decomposition is performed without desorbing odor. In terms of shape, a corrugated honeycomb type is desirable in order to obtain sufficient adsorption performance.
[0028]
In the embodiment, a high-performance HEPA filter is used. However, a filter that can be used in the present invention is a high-performance dust collecting filter. It is desirable to have a separate blower circuit.
[0029]
In the embodiment, the sirocco fan is used as the second blower fan, but the present invention is not limited to this as long as the fan has a high static pressure. However, there is no other device capable of exerting the capability without any problem even if the current pressure loss is 5 mmAq or more.
[0030]
In the embodiment, the first air blowing circuit has no air purifying function. However, if the pressure loss is small, the air blowing device has almost no influence on the cooling / heating performance. is there.
[0031]
FIG. 9 is a vertical sectional view taken along line BB of the indoor unit shown in FIG. 3 for the air conditioner configured by dividing the heat exchanger into three parts. Since the components are almost the same as those in the first embodiment, the description will not be repeated.
[0032]
【The invention's effect】
As is apparent from the above embodiment, according to the first aspect of the present invention, it is quite difficult to provide a device having a sufficient air cleaning function in one blower circuit with a low pressure drop (about 1 mmAq or less). However, by using two air blowing circuits, a sufficiently high cooling and heating effect can be achieved in the first air blowing circuit, and a sufficient air cleaning function can be provided in the second air blowing circuit.
[0033]
Furthermore, by arranging the second blower circuit, which is smaller than the first blower circuit, on the back side, it was possible to effectively use the space that was a dead space in the indoor unit shape of a quarter-arc fan. . Also, the relationship between the second suction grille and the second outlet can be effectively utilized by setting the second outlet on the farther side.
[0034]
According to the invention as set forth in claim 2 , the path leading to the second outlet through the second blower fan is constituted by a flexible pipe, so that the second outlet can be set in accordance with the state of routing of the refrigerant pipe performed during construction. It can be installed at the optimum position, and the installation workability has been improved.
[0035]
According to the third aspect of the present invention, the second blower circuit can be integrated as a unit and can be detachably attached to be an optional function of the air conditioner, and may be provided in another room in some cases. It can be installed and moved to another air conditioner having a compatible function. As a result, the range of application of the air conditioner according to the present invention is expanded.
[0036]
According to the fourth aspect of the present invention, the deodorizing performance can be improved by arranging the device dedicated to deodorizing.
[0037]
According to the fifth aspect of the present invention, the dust collection performance can be improved by arranging the device dedicated to dust collection.
[0038]
According to the invention of claim 6, in order to obtain sufficient deodorizing performance in one pass, a filter type adsorbent is preferable even if the pressure loss is somewhat large. In order to regenerate this adsorption filter instead of disposable, it can be used semi-permanently by performing maintenance using a method such as light regeneration or heat regeneration.
[0039]
According to the invention of claim 7, in order to obtain sufficient dust collecting performance in one pass, a filter type filter is preferable even if the pressure loss is somewhat large. Although it is disposable, the pleated type makes maintenance-free for a long time possible. At present, there is a five-year level, and in the future a ten-year level is possible, and although maintenance is required, it is not annoying.
[0040]
According to the invention as set forth in claim 8 , although the first blower fan is a cross flow fan as in the related art, the second blower fan is a sirocco fan, so that a high pressure loss is arranged in the wind circuit. Since the static pressure is high, there is no problem as a real machine.
