Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner in an indoor unit of a general residential air conditioner.

Conventional technology Conventionally, separate air conditioners for residential use have an outdoor unit and
The indoor unit is installed in a position as shown in FIG. That is, a wall-mounted indoor unit 3 or a floor-standing indoor unit 4 connected to an outdoor unit (not shown) is provided in the indoor unit 2 of the house 1, and the indoor unit 2 is cooled and heated from the wall surface, or the indoor unit 2 is cooled and heated from the floor side. It was hot.

Problems to be Solved by the Invention In such conventional configurations, both wall-mounted and floor-standing types perform air conditioning and heating from the corners of the room 2 toward the center, so a sufficient temperature distribution cannot be obtained. The temperature distribution in the central area, which is the actual living space, is poor. Particularly in severe cold weather, heating starts slowly, and it takes a considerable amount of time to warm up the living space.

The present invention solves these problems,
The purpose is to improve the temperature distribution in the living space and to speed up the start-up, especially during heating.

Means for Solving the Problem In order to solve this problem, the present invention provides a main body of the indoor unit such as a beam or girder in the attic, and provides an indoor light fixture in the center of the outlet of the blower in the main body. A blow-off duct is provided around the indoor light fixture and extending to near the position of the light.

Effect With this configuration, indoor air that flows in from the indoor return air duct passes through the air intake port of the main unit, passes through the indoor heat exchanger, becomes cold air and warm air, and then flows into the living space through the blow-off duct connected to the blower outlet. Cold and hot air will be blown into the vicinity.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. House 7 as shown in Figure 3
The main body 1 of the thin ceiling-mounted air conditioner is attached to the ceiling beam 8 and the hanging bolt 9 in the ceiling 30 under the second floor floor
0 is suspended, and an indoor electric light 12 for indoor lighting is installed in the center of the air duct 11 of this main body 10 so as to be located below the ceiling surface 16, and a low table in the substantial living space 13 is installed. Light up the area near people 15 who are using 14 or kotatsu, etc.
Moreover, cold/warm air is blown out from the blow-off duct 11. An indoor suction port 18 is provided on the ceiling of the house in order to return air from the indoor 17 side to the main body 10, and the indoor suction port 18 is connected to the indoor return air duct 19.
is connected to one side of the main body 10 by.

The main body 10 will be explained with reference to FIG. The main body 10 has an intake port 20 connected to the indoor return air duct 19 on one side thereof, and an indoor heat exchanger 21 connected to an outdoor unit (not shown) through refrigerant (or cold/hot water), A blower 22 for indoor air circulation is provided in correspondence with the exchanger 21. A discharge port 23 of the blower 22 is provided on the lower surface side of the main body 10.
A bottom plate 25 with a socket 24 to which a household electric wire (not shown) is connected is fixed, a cord 26 is provided at an appropriate length downward from the socket 24, and an indoor light 12 is connected to the bottom plate 25. A light fixture 28 is provided. The indoor light fixture 28 has a round shape around the periphery, extends to almost the same position as the lower end of the indoor light 12, and is fixed and connected to the bottom plate 25 with screws 29 at the upper end. The blower duct 11 is connected to the outlet 23 of the blower 22. The blow-off duct 12 has a shape that is curved outward at its lower part 11a to match the shape of the umbrella part 12a of the indoor light 12. In this embodiment, since the indoor light 12 is round, this round shape is formed. Although the lower part 11a is rounded in accordance with the shape, the umbrella part 1 of the indoor light 12
If 2a has a rectangular shape, the lower portion 11a will also have a rectangular shape. Further, the air outlet 31 of the air outlet duct 11 is provided with a circular louver 32 so as to blow air slightly outward as shown in FIG.
The entire circumference is divided into four parts so that the blowing direction can be changed to a certain extent, and interlocking plates 34 are provided between the partition plates 33 to interlock with each other.

In the above configuration, by operating the blower 22 of the main body 10, air near the ceiling flows in from the indoor suction port 18 of the indoor room 17, and the air near the ceiling flows into the indoor return air duct 19.
The air then passes through the indoor heat exchanger 21 from the intake port 20, and becomes cold air for cooling and warm air for heating, and is sent to the blower 22.
Passes through the inside of the blow-off duct 11 from the discharge port 23 through the
The air is rectified by the louver 32 of the air outlet 31 and blown out toward the living space 13 (FIG. 2) while being directed. Since the indoor light fixture 28 is installed almost in the center of the room, the air is blown out from around the indoor light fixture 28, thereby cooling and heating the room 17 from the living space 13. , and the main body 10.

As a result, compared to the case where the indoor unit is installed on the wall or floor of the room, it does not require any indoor space at all, and like a wall-mounted indoor unit, it can be installed with furniture and other furnishings. is also no longer necessary.

In this embodiment, the indoor suction port 18 is provided on one side of the room, but the main body 10, that is, the indoor electric light fixture 28 is the central core, and the indoor inlet 18 is provided on the ceiling surface on both sides.
The air intake port 2 of the main body 10 is provided with a plurality of indoor air intake ports.
0, in which case the air will be circulated throughout the room, further improving the temperature distribution. Furthermore, although the blow-off duct 11 is round, it can easily be formed into a semicircle or square shape, divided into two parts, or provided only on one side.

Effects of the Invention As is clear from the description of the above embodiments, the present invention provides an indoor light fixture on the outlet side of the blower in the main body, and provides the following features around the indoor light fixture:
In addition, the air duct was installed to extend downward and toward the living space, so that the living space was effectively cooled or heated first, so that when cooling or heating, the air flow started from the living space. While heating and cooling, a temperature distribution is obtained from the central part toward the indoor suction port, and the overall temperature distribution in the room is improved. Particularly when heating, it takes a considerable amount of time to warm up the entire room, but since warm air is blown into the living space first, the heating effect can be felt as a practical experience even in the coldest weather, and the heating effect can be experienced in a short period of time. This has the effect that the following can be obtained.
