BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly to an air conditioner having a function of deodorizing blown air and adding aroma to the blown air.

[0002]

2. Description of the Related Art Examples of conventionally known air conditioners having functions of deodorizing blown air and adding fragrance to the blown air include those shown in FIGS. In any of these, a deodorizing agent and an aromatic agent are added to a dust filter 2 provided at an air inlet 1 of an air conditioner.
1 is disposed so that air that has been deodorized and / or fragrance added is drawn into the fan 3. Also, a layer of deodorant and fragrance is formed on the leeward side of the dust filter,
Some air is subjected to deodorization and / or fragrance addition to the dedusted air.

[0003]

However, in such a conventional technique, in order to improve the efficiency of deodorization and fragrance addition, it is necessary to increase the thickness of the deodorant and fragrance layers. Two conditions are needed to optimize the flow rate of the air passing through the (deodorizer, fragrance layer). However, thicker layers increase the load on the fan motor,
When the wind speed passing through the deodorant and fragrance layers is made slower than that at the suction port, it is necessary to increase the surface area of the deodorant and fragrance layers by making the layers corrugated and increasing the size of the air conditioner. there were. For this reason, it was not easy to optimize the flow rate of the air passing through the deodorant / fragrance, and it was difficult to improve the efficiency of deodorization and fragrance addition.

Further, in the case where the deodorizing agent and the fragrance are disposed in the dust removing filter, the life of the deodorizing agent and the fragrance is different from that of the dust removing filter. Since it is difficult to recover and regenerate the freshener / fragrance, the dust filter has been disposable together with the deodorant / fragrance disposed therein. In other words, the one in which the dust filter and the deodorant / fragrance are integrated,
Originally, the reusable dust-removing member was disposable if it was originally washed, or the dust-removing member was made to be a non-washable material for disposable use, resulting in an increase in maintenance costs.

An object of the present invention is to improve the efficiency of deodorization and fragrance addition of an air conditioner having a deodorization and fragrance addition function.
The purpose is to reduce the maintenance cost.

[0006]

Means for Solving the Problems A flow path for deodorizing / adding fragrance is formed between a high static pressure section and a low static pressure section in the air conditioner, and the flow path of the deodorizing / fragrance adding air is formed in the air flow path. Place the deodorizing and fragrance layer filled in the removable cartridge. A section having a high static pressure is preferably a section on the discharge side of the fan and upstream of the heat exchanger, and a section having a low static pressure is preferably a section on the suction side of the fan and downstream of the dust filter. is there.

[0007]

The air flows from the section having a high static pressure to the section having a low static pressure through the flow path of the deodorizing / fragrance adding air. While the air flowing through this air flow path passes through a layer of deodorant / fragrance filled in a cartridge arranged in the middle of the air flow path,
Deodorized and / or scented. Since the air flow path communicates the discharge side and the suction side of the fan, the wind speed of the air flow path can be set independently of the wind speed of the air passing through the dust filter or the heat exchanger.

The supply duct 12, the case 9, and the return duct 8 form an air flow path for deodorizing and adding fragrance.

The dust filter 2 is disposed without any gap over the entire horizontal cross section of the casing 20, and the section 20BL is composed of the upper section 20BLU and the lower section 20BLL of the dust filter 2.
Are divided into The fan motor base 5 is also arranged so as to cover the entire horizontal section of the casing 20 except for the opening 24. The section 20BU is also divided by the heat exchanger 6 into an upper section 20BUU and a lower section 20BUL.

The wall surface 25 which forms a part of the wall surface of the case 9
Is provided with a door (not shown) so that the cartridge 10 can be attached and detached by opening the door.
The cartridge 10 is a double cylinder having a bottom formed by a fine mesh and filled with a deodorant and / or a fragrance between the inner cylinder and the outer cylinder. The deodorant and / or the fragrance are filled so that air can sufficiently pass from the inside of the inner cylinder to the outside of the outer cylinder. The return duct 8 is connected to the upper surface of the case 9 and has its end protruding downward into the case. The cartridge 10 has its open end inner periphery fitted to the outer periphery of the protrusion of the return duct 8. It is configured to be fixed.

In a section 20BLU between the fan motor base 5 and the dust filter 2 where the static pressure is the lowest, a discharge port of a supply duct 12 for discharging air after the deodorizing and aroma addition processing is arranged. In a section 20 BUL having the highest static pressure between the exchangers 6, an inlet of a return duct 8 for sucking air before the deodorization / fragrance addition processing is arranged.

Hereinafter, the operation of the apparatus having the above configuration will be described.
When the fan 3 is driven, room air is sucked into the casing 20 from the suction port 1 as return air. The return air sucked into the casing 20 is sucked into the fan 3 through the dust filter 2, and the opening 20BU through the opening 24.
It is sent to L. The air that has entered the section 20BUL is heated or cooled while passing through the heat exchanger 6, and is then blown into the room from the outlet 7. Therefore, the section 20 BLU between the dust filter 2 and the fan motor base 5 has the lowest static pressure, and the section 20 BUL between the fan motor base 5 and the heat exchanger 6 has the highest static pressure. As a result, while the air sucked from the suction port 1 is being sent to the heat exchanger 6 by the fan 3, a part of the air is generated by the pressure difference between the return duct 8 suction port and the supply duct 12 discharge port. Flows into the cartridge 11 filled with the deodorant / fragrance. The air which has passed through the deodorizing / fragrance layer of the cartridge 11 and has been subjected to the deodorizing / fragrance adding treatment is sucked by the fan 3 and flows out to the section 20 BLU, and is mixed with the return air flowing into the section 20 BLU via the dust filter 2. The heat is sent to the heat exchanger 6 while being passed through the heat exchanger 6, and then sent out of the room through the outlet 7.

The above operation is repeated, and the entire room air is subjected to deodorization and / or fragrance addition. When the life of the dust filter 2 or the life of the deodorant and / or the fragrance 11 has expired due to long-term use, replacement or cleaning / regeneration is individually performed at the end of the life.

Therefore, according to this embodiment, the cartridge for the deodorizing and fragrance and the dust filter are separately disposed, and a part of the return air in the room is bypassed from the fan outlet to the cartridge, so that the air passes through the deodorizing and fragrance. The wind speed of the air to be made and the thickness of the deodorant / air freshener layer can be optimized,
It has become possible to improve the performance of deodorization and fragrance addition. In addition, it is possible to replace the deodorizing / fragrance and dust filter according to their respective service lives, and the cartridge itself can be downsized with the improvement of the deodorizing / fragrance adding performance.
Because it can be stored inside the air conditioner, workability such as replacement is improved. Furthermore, since the introduction of air into the cartridge filled with deodorant and fragrance is performed using the differential pressure inside the air conditioner, no new power is required, and there is no movable part. There is nothing.

Next, a ceiling-embedded type air conditioner according to a second embodiment of the present invention will be described with reference to FIG. The illustrated air conditioner has a box-shaped outer casing 30 having an open lower end.
And a compartment 32 which is provided in the box-shaped casing 30 and forms an air discharge flow path between the box-shaped casing 30 and an inner wall surface thereof.

The cartridge 10 has the same structure as that of the first embodiment, and the return duct 8 is also provided in the first embodiment.
Similarly to the embodiment, the end on the case 9 side is
Of the cartridge 1
Numeral 0 is detachably fitted and fixed to the protruding portion. Also,
In the present embodiment, the bottom surface of the case 9 and the dust filter 2 below the case 9 are configured as doors that can be partially opened by hinges, and when these doors are opened, the cartridge 10 is taken out of the case 9. You can do it.

In this embodiment, the case 9 is a section 3 having the lowest static pressure between the dust filter 2 and the fan motor base 5.
Since it is arranged inside the 2BLU, there is no need to provide the supply duct 12 in the first embodiment. Cartridge 1 from section 32 BUL via return duct 8
After passing through the layer of the deodorant and fragrance of the cartridge 10, the air flowing into the cartridge 32 directly flows through the opening (case discharge port) 16 provided in the case 9 into the compartment 32 BLU, and the dust filter 2. , Is sent to the heat exchanger 6 while being mixed with the return air flowing into the section 20BLU through the section 20BLU. After passing through the heat exchanger 6, the air is sent out from the outlet 7 through the section 32BUU to the room.

In this embodiment, as in the first embodiment, the dust filter 2 and the deodorant and / or fragrance 11 are also used.
Are separated and separately removable, so that they can be replaced or washed and regenerated according to their life, and can be used until their life is over. The increase in maintenance cost is suppressed, and the same effects as obtained in the first embodiment can be obtained.

FIG. 5 shows a third embodiment of the present invention in which the present invention is applied to a ceiling-suspended air conditioner. The illustrated air conditioner has a rectangular box-shaped casing 50 having an opening serving as an outlet 7 on one of the surfaces that are vertical when installed, and the outlet 7 on a wall surface 51 serving as a bottom when the casing 50 is installed.
Suction port 1 formed on the side far from
Is divided into a section provided with the outlet 7 and a section 50C provided with the suction port 1, and a section 5 provided in the section provided with the outlet 7 and provided in the section provided with the outlet 7.
A heat exchanger 6 that divides the air into a section 50B that is in contact with the fan motor base 5 and a section 50B that is in contact with the fan motor base 5; 50
B, a case 9 having a cartridge 10 therein and arranged in a section 50C, a supply duct 8 communicating the inside of the case 9 with the section 50B, and a dust removal removably mounted on the suction port 1. The filter 2 is included.

In this embodiment, the cartridge 10 has the same construction as that of the cartridge of the first embodiment, and the case 9 has a case outlet communicating between the inside of the case 9 and the inside of the section 50C as in the second embodiment. An outlet 16 is provided.
In addition, the bottom surface of the case 9 and the dust filter 2 below the case 9 are configured as doors that can be partially opened by hinges.
Can be taken out of or attached to the case 9.

The section 50C has the lowest static pressure because the internal air is sucked into the fan 3 and has a resistance to the air sucked by the dust filter 2, and the section 50B has the lowest static pressure.
Since the air is sent from the fan 3 and the heat exchanger 6 has resistance, the static pressure is highest. The air sucked from the room through the dust filter 2 by the fan 3 is sent to the section 50B through the opening 54, and is heated or cooled by the heat exchanger 6 and then returned to the room again through the outlet 7.
As described above, since the section 50B has a higher static pressure than the section 50C, a part of the air sent to the section 50B flows into the cartridge 10 housed in the case 9 via the return duct 8, The deodorant and / or fragrance filled in the cartridge 10 while passing through the cartridge 10 undergoes deodorization and / or fragrance addition processing.
The air subjected to these processes is sucked at a low static pressure and flows out of the case 9 via the case discharge port 16 to the section 50C. The treated air that has flowed out to the section 50C is sent to the heat exchanger 6 while being mixed with the return air flowing into the section 50C via the dust filter 2, and after passing through the heat exchanger 6, passes through the section 50A and is blown out. It is sent out from 7 to the room.

In this embodiment, the same effects as those of the first and second embodiments can be obtained.

In the second and third embodiments, the case 9 is provided with a door so that the cartridge can be directly removed from the case 9.
The cartridge 9 can be taken out of the case 9 after the case 9 is once taken out of the inner casing 32 or the casing 50. By doing so, the work of opening and closing the door of the case 9 in a narrow place can be eliminated, and the maintenance work can be facilitated.

[0024]

As described above, according to the present invention, an air flow path is formed between a high static pressure section and a low pressure suppression section in an air conditioner, and the air flow path is removed from the air flow path. Since the deodorizing and fragrance layer filled in the possible cartridge is arranged, the thickness of the deodorizing and fragrance layer is independent of the wind speed passing through the air inlet of the air conditioner and the speed of the air passing through the heat exchanger. And the speed of air passing through the deodorizing and fragrance layer can be set, improving the efficiency of deodorizing and adding fragrance, and enabling the dust filter and deodorizing and fragrance to be used until their life has expired. As a result, maintenance costs (operating costs) have been reduced.
