Abstract

PURPOSE:To provide uniform indoor temperature distribution and to enable execution of air conditioning with high amenity by a method wherein an indoor unit is provided at an indoor unit body, having suction ports and a discharge port, with a heat exchanger and a blower, and the suction ports are formed in the vicinity of the four side end parts of the body. CONSTITUTION:Indoor air sucked through a suction port 13 is cooled by a heat exchanger 12, and is distributed through a blower 18 into three directions of an upper draft air duct 20, a left draft air duct 22, and a right draft air duct 23, and cold air is discharged through each draft air duct. During heating operation, a damper 24 is driven so as to close the upper air draft duct 20, and through running of the blower 18, indoor air is sucked through the suction port 13 and heated by a heat exchanger 12. The indoor air is distributed through the blower 18 to three directions of a lower draft air duct 21, the left draft air duct 22, and the right draft air duct 23, and hot air is discharged through each draft air duct.

), the indoor air is removed from the air intake port (3).
It is sucked in by the heat exchanger (2) and cooled.

Cool air is blown out from the upper air outlet (5). On the other hand, during heating, as shown in FIG. ), heated by the heat exchanger (2), and hot air is blown out from the lower outlet (9).

[The problem that the invention attempts to solve]

Since the indoor unit of a conventional air conditioner is configured as described above, it is also more expensive in terms of cost than the upper and lower blowers, which require 141 + 612 pieces. In addition to giving an unpleasant feeling of airflow to the room, there are also problems in that the cold or warm air does not spread from side to side within the room, resulting in uneven temperature distribution.

This invention is the ninth incarnation to solve the above-mentioned problems.The optimal blowing direction can be selected depending on whether the air is cold or warm, creating a comfortable indoor environment with no sense of airflow and no temperature unevenness. Another object of the present invention is to obtain an indoor unit of an air conditioner that can reduce the number of blowers.

[Tth means to solve the problem]

An indoor unit of an air conditioner according to the present invention is:

It is equipped with an indoor unit body having an inlet and an outlet, a heat exchanger and a blower provided in this body.

The air outlet is provided near the ends of the four sides of the main body.

It is also effective to provide a damper at the outlet.

[Effect]

The indoor unit of the air conditioner in this invention is:

The heat exchanger heat-exchanges the ratio-conditioned air, which is then blown into the room by a blower from outlets provided near the four ends of the main body.

'1. Opening and closing of each outlet is controlled by nine dampers provided at each outlet.

〔Example〕

In Figures 1 and 2, αυ is a floor-standing indoor unit;
FIZ is a specific heat exchanger located approximately in the center of the indoor unit main body συ, (I3 is an indoor air intake port, (14 is an upper air outlet provided at the top of the indoor unit α9, and 05 is a specific heat exchanger located in the indoor unit main body συ. There are nine lower air outlets installed at the bottom of the
αG is a left air outlet provided on the left side of the indoor unit main body (lυ), αD is a right air outlet provided on the right side of the indoor unit main body Qll, and 11 is a right air outlet provided in the center of the indoor unit main body αB. A centrifugal blower, C9, is the tth fan motor that drives the blower for 0 seconds.f7t■ is an upper air passage connecting the blower αl and the upper air outlet, C0
i23 is a lower air passage connecting the blower 08 and the lower air outlet, and i23 is a left air passage connecting the air blower 08 and the left air outlet.

@ is a right air passage connecting the blower a1 and the right air outlet.

In the above configuration, by operating the blower (I8), indoor air is sucked in from the suction port 0, and the air is drawn into the heat exchanger t1.
3, the cooling tank is heated and passed through the blower OI.

It is divided into four directions: the upper air duct, the lower air duct t21+, the left air duct, and the right air duct (c), and passes through each air duct upward from the upper air outlet α, and from the lower air outlet o9. Downward, from left outlet 1 ae to left, right outlet Q7+

Indoor air is sucked in through intake port Q3.

It is cooled by the heat exchanger a3, passes through the blower 0 ladder, is distributed into three directions: the upper air passage ■, the left air passage, and the right air passage, passes through each of the above air passages, and then exits the upper air outlet a4. Cool air is blown upward, to the left from the left outlet αe, and to the right from the right outlet θ, and during heating operation, the damper l′! 4 is driven so as to block the upper air passage ■, and by operating the air blower 0, the indoor air is sucked into the suction port from 3, heated by the heat exchanger az, passed through the air blower ill, and is sent to the lower air blower.

Pass through each of the above air ducts and go downward from the lower air outlet a9.

Hot air is blown out to the right from the left outlet (from IG to the left, right outlet T1?).

In the above-mentioned embodiments, the indoor unit main bodies all are placed on the floor of the room, but the present invention is not limited to this, and it goes without saying that it can also be applied to, for example, a window-mounted or ceiling-mounted type.

〔Effect of the invention〕

As described above, the present invention includes an indoor unit main body having an inlet and an air outlet, a heat exchanger and a blower provided in this main body, and the air outlet is located near the four side ends of the main body. Since the system has nine configurations, it is possible to create a uniform temperature distribution in the room, and it is also possible to suppress the feeling of air currents, resulting in the effect of highly comfortable air conditioning.

By installing a damper at each outlet.

It is possible to select an appropriate outlet for each of cooling operation and heating operation.
