Description

[Detailed description of the invention] This invention relates to an improved structure suitable for, for example, a ceiling-embedded air conditioner in which the unit body is buried within the wall of a house, and in particular facilitates cleaning of the condensation pan housed within the unit body. This is what I did.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. 1 and 2 are plan views and front views showing the internal structure, and FIG. 3 is a bottom view. Hereinafter, the same parts will be described with the same reference numerals.

1 is a T-shaped air conditioner body with a machine room 2 at the bottom of the main body and a wide heat exchange ventilation chamber 3 at the top.The machine room 2 has a compressor 4 and a water-cooled heat source side heat exchanger. An electrical equipment box 5 (not shown) is installed in the heat exchange ventilation chamber 3, and a pair of user-side heat exchangers 6a and 6b facing each other are placed on the left and right sides, and a dew pan 7 is fixed below the heat exchangers 6a and 6b. A pair of centrifugal blowers 8a, 8b facing each other and a pressure equalization chamber 9
It stores a and 9b.

The centrifugal blowers 8a and 8b have suction nozzles 10a and 10b and a two-way discharge casing 11, respectively.
a, 12a, 11b, 12b, Sirotskov fans 13a, 13b and electric motors 14a, 14b.
b, 12b are connected to pressure equalizing chambers 9a, 9b, respectively.

15 is a decorative panel provided at the center of the lower surface of the main body, 16 is a decorative frame, and an air intake port 1 is provided in a pair of opposing long side gaps formed by this panel and the frame.
7a and 17b, air outlets 18a and 18b are provided in a pair of opposing short side gaps.

19a and 19b are suction ducts that are detachably attached to the left and right outer sides of the machine room 2, and the lower ends are connected to the air suction ports 17a and 17b, and the upper ends are connected to the utilization side heat exchanger 6a,
The suction duct 19 is connected to the windward side of 6b.
1 divided by a, 19b and partition walls 20a, 20b
The pair of blow-off ducts 21a and 21b have their upper ends connected to the pressure equalization chamber 9.
a, 9b have their lower ends communicated with air outlets 18a, 18b.

Further, the dew catcher 7 is divided into a main catcher 22 which is tilted downward and is fixed within the main body, and an auxiliary catcher 23 which is detachably attached. A part of the air blowers 8a, 8b are Sirotskov fans 13a, 13b.
The remaining dew water that is scattered and drips onto the main saucer 22 and adheres to one of the user-side heat exchangers 6a and flows down without being scattered is directly dripped onto the main saucer 22, and is dropped directly onto the other user-side heat exchanger 6a. The remaining dew water that adheres to the container 6b and flows down without being scattered is dripped directly onto the auxiliary saucer 23. The dew water dripped onto the main tray 22 in this way descends along the main tray 22 and is collected in the auxiliary tray 23, together with the dew water dripped directly onto the auxiliary tray 23 from the user-side heat exchanger 6b. The water is discharged outdoors from the drain port 24 via a drain hose 25.

26a and 26b are air filters 27 which are detachably housed in the suction ducts 19a and 19b;
is the ceiling.

With such a configuration, indoor air from the suction ports 17a and 17b flows into the suction ducts 19a and 19 from the front and rear directions.
b branched into the air filters 26a, 26
Utilization side heat exchangers 6a, 6b after being filtered by b
They are cooled during cooling, heated during heating, and merge in the center of the heat exchange ventilation chamber 3, after which the suction nozzles 10a,
The distribution direction is changed in the front-rear direction by the suction action of the Sirotsukofans 13a and 13b into the interior of the 10b, and the distribution direction is changed and sucked. The sucked cold air or warm air is distributed and discharged from the two-way discharge casings 11a, 12a and 11b, 12b to the left and right sides, respectively, to the pressure equalization chambers 9a, 9.
They merge again at b, and the pressure is equalized, and the blowout duct 2
After descending from 1a and 21b, the left and right air outlets 18
It comes to be uniformly sent into the room from a and 18b.

The T-shaped air conditioner body 1 is first stored in the ceiling 27 space and fixed with mounting brackets (not shown), and then the suction ducts 19a, 19b and the blow-out duct 21 are connected to the ceiling 27 space.
The air filters 26a, 26b are attached to the decorative panel 15 and the decorative frame 16 and fixed with bolts 28a, 28b, so that the installation work can be easily performed. Also, when cleaning and replacing the air filters 26a, 26b, the set screws 29 are removed and the decorative panel 15 is fixed.
It can be easily attached and detached by rotating it downwards on the hinges 30, 30 to open it.

In particular, the entire dew pan 7, which is disposed inside the main body and straddles above the machine room 2, cannot be removed and cannot normally be cleaned, but according to the present invention, the decorative panel 15 can be opened to Filter 26b
After removing the suction duct 19b, the worker leans into the suction duct 19b from below, removes the auxiliary tray 23, and pulls it out from the suction duct 19b to the indoor side. You can easily remove moss etc.

When attaching or removing the auxiliary saucer 23, the drain port 24 should be positioned within the socket 31 of the fixed drain hose 25, and the upper edge 32 of the auxiliary saucer 23 should be brought into close contact with the lower edge 33 of the user-side heat exchanger 6b. Exposure water treatment and air seal treatment can be performed without any problems, and the bolt 28
a, 28b are removed and the suction and outlet ducts 19a,
If 19b, 21a, and 21b are removed together with the decorative panel 15 and decorative frame 16, a larger space for service can be obtained and cleaning work can be performed more easily.

In the above embodiment, the main saucer 2 where dew water flows down
2 is less likely to grow moss than the auxiliary saucer 23 where dew water temporarily accumulates, and you can occasionally clean the space from which the auxiliary saucer 23 is removed with a brush, but to make the work even easier, use the cleaning method shown in Figure 4. As in other embodiments shown in (additional notes with the same reference numerals), the dew pan 7 is composed of a fixed chevron-shaped main tray 22' and removable left-right symmetrical auxiliary trays 23a, 23b. The suction ducts 19a, 19 respectively
Main saucer 2 can be removed with a short brush by pulling it out individually from b.
2' can be easily cleaned.

In addition, in other embodiments, some of the dew water adhering to the user-side heat exchangers 6a, 6b is removed by the blowers 8a, 6b.
It is scattered by the Shirotsuko fans 13a, 13b of 8b and drips onto the main saucer 22', and this main saucer 2
The remaining dew water that descends along the auxiliary trays 2' and collects in the auxiliary trays 23a, 23b, and flows down the user-side heat exchangers 6a, 6b without being scattered is directly dripped onto the auxiliary trays 23a, 23b, respectively. Discharged outdoors.

As described above, the proposed air conditioner has a pair of suction ducts that communicate with the air suction port on the bottom of the main body, a machine room installed between the two ducts to house the compressor, and a dew pan installed above the machine room. and a pair of heat exchangers provided above both ends of the dew pan, and a blower that sends the intake air that has passed through both the heat exchangers from the air outlet into the air-conditioned room through a pair of air outlet ducts. , a main tray in which the dew tray is provided between a pair of heat exchangers so as to be inclined downwardly, and a space in the suction duct that spans a lower position of the lower edge of the main tray and a lower position of the heat exchanger. Since it is constructed with an auxiliary saucer that can be attached and removed more freely, the large dew saucer placed astride the pair of heat exchangers can be easily removed by removing the divided small auxiliary saucer. In addition to being easy to clean, this auxiliary tray can be removed and the suction duct can be used as a service space, allowing the air conditioner to have a compact and rational structure. It is extremely suitable for
