Abstract

PURPOSE:To reduce the temperature variation in the room even if the installation is made in the ceiling close to the wall surface by fixing the direction of air blown out of the room side outlet in the room and disposing a louver in the center side outlet to change the direction of air vertically. CONSTITUTION:When cross flow fans 4, 5 and an electric motor 22 are operated, the room air is taken in from an intake grill 12 in a cosmetic panel 11 and blown out of two outlets 13, 14 after being temperature-conditioned by heat exchangers 6, 7. In this process, the air delivered out of the outlet 13 near the wall is directed downward by a second guide plate 18, and the flow of the air delivered out of the outlet 14 near the center of the room is driven by the electric motor 22. The air is guided to the center of the room as it is vertically shifted by the oscillation of a louver 19. Therefore, even if an air conditioner 1 is installed in the ceiling near to the wall of the room, the temperature variation in the room can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a ceiling-mounted air conditioner that is installed on the ceiling of a room.

(b) Conventional technology An example of the structure of a ceiling-mounted air conditioner is
The one shown in Japanese Patent No. 125424 has been disclosed.

The air conditioner shown in this publication has a suction port in the center, and elongated air outlets on both sides of the suction port.

This machine has a built-in heat exchanger for temperature control and a blower, and as the blower rotates, indoor air is sucked in through the suction port, temperature-controlled by the heat exchanger, and then sent out from the two air outlets. This was done so that the air could be expelled.

(c) Problems to be solved by the invention When such an air conditioner is installed, for example, on the ceiling in the center of a room, the air discharged from the two outlets spreads throughout the room and the temperature inside the room increases. Unevenness is unlikely to occur. However, in ordinary homes, lighting equipment such as Jumpria is installed in the center of the indoor ceiling, so air conditioners are often installed on the ceiling close to the walls of the room. The air that was completely discharged from the machine was difficult to reach the center of the room, and there was a risk that the temperature in the room would become uneven.

An object of the present invention is to minimize temperature fluctuations in the room even when installed on a ceiling close to a wall in the room.

(d) Means for solving the problem In order to achieve this object, the air conditioner of the present invention is provided with a plurality of elongated outlets parallel to the wall of the room, and the air is blown from the outlet on the wall side of the room. The direction of the wind is fixed, and a louver is disposed at the outlet in the center of the chamber to automatically change the direction of the discharged wind in the vertical direction.

(e) The air discharged from the outlet on the working wall side is made to flow along this wall, and the direction of the air discharged from the outlet on the center side of the chamber is automatically changed to flow toward the center of the room. This is what I did.

(F) Embodiment In Fig. 1, 1 is an air conditioner embedded in the ceiling, and has an outer panel 2 bent into a substantially U-shape so that the opening is positioned downward, and a bent portion 3 of this outer panel. Two cross-flow fans 4.5 arranged along the two fans, and two plate-fin type heat exchangers 6.7 arranged between the two fans and combined in a substantially V-shape are built-in. This reheat exchanger 6゜7 is a combination of a cooler and a hot water coil, and during cooling, the refrigerant flows through the refrigerant vibes 8 installed on both the left and right sides of the heat exchanger as shown by the solid arrows, and during heating, the refrigerant flows through the refrigerant vibes 8 installed in the center. Hot water is made to flow through the hot water pipe 9 as shown by the dashed arrow.

10 is a drain pan disposed below this reheat exchanger;
Reference numeral 11 denotes a decorative panel for closing the opening of the outer panel 2, and a suction grill 12 is formed in the center, and elongated air outlets 13 and 14 are formed on both sides of the suction grill. The suction grill faces the space 15 between the two heat exchangers 6 and 7,
The air outlets 13 , 14 lead to air channels 16 in the skin 2 .

Reference numeral 17 is a first wind guide plate disposed along the longitudinal direction of one of the air outlets 13, which is supported so as to be movable by hand in any direction. Reference numeral 18 denotes a second wind guide plate disposed along the lateral direction of one of the Suita exits 13, and this wind guide plate is stepped up in a number of stages in the longitudinal direction.

Reference numeral 19 denotes a louver disposed in the longitudinal direction of the other outlet 14, and a notch 21 is formed in the center of the upper piece 20 of this louver.
is provided, and the eccentric shaft 23 of the electric motor 22 is inserted into this notch =3-. When the eccentric shaft 23 rotates due to the rotation of the electric motor 22, the louver 19 swings about the fulcrum 24 as shown by a chain line.

In many cases, lighting fixtures are installed at the center of the ceiling surface in the rooms of ordinary households, and for this reason, the above-mentioned air conditioner is installed at the center of the ceiling surface 25, as shown in FIGS. 2 and 3. It is often installed at a more remote location, that is, closer to the wall surface 26. In this case, the ceiling surface 25 is placed so that one Suita outlet 13 is on the wall side and the other outlet 14 is on the center side of the room.
Install this air conditioner 1 at In the air conditioner 1 installed in this way, when the cross flow fan 4.5 and the electric motor 22 are operated, indoor air is sucked in through the suction grill 12 of the decorative panel 11, and the heat exchanger 6,
The temperature is controlled at step 7 and it is discharged from the two air outlets 13 and 14 (
(See solid line arrow in Figure 1). At this time, the air discharged from one Suita outlet 13 is directed to this outlet 1 by the second guide plate 18.
3 in the downward longitudinal direction. Also, the other outlet 1-
4= The flow of air discharged from 4 is guided toward the center of the chamber while being changed in the vertical direction by the swinging of the louver (see solid line arrows in FIGS. 2 and 3).

Figure 4 shows the indoor temperature lf when heating a room with a height of 2.5 m and a length of 9.0 m using this air conditioner 1.
Allow the two cross flow fans 4 and 5 to rotate at 180 rpm, and the air volume discharged from each outlet is 400 m''
/h. As can be seen from this figure, the temperature of the living space near the indoor floor 27 is approximately 27°C to 30°C.
°C, and the unevenness of indoor temperature has been suppressed.

The temperature in the center of the room was higher than the temperature near the air outlet 13 and 14 of the air conditioner 1 because the air flow in this area was slower than the air flow near the air outlet. it is conceivable that. Figure 5 is an indoor temperature distribution diagram when heating operation is performed with the movement of the louver 19 of the air conditioner 1 stopped.
It was rotated at 0 rpm, and the air volume discharged from each outlet 13 and 14 was set to 400 m''/h.

As you can see from this figure, the temperature is around 24°C to the right of the center of the chamber, and 2600 to 30°C to the left.
The temperature was around C, and the temperature unevenness in the room was larger than in Fig. 4.

In the above embodiment, the air conditioner is mounted on the ceiling so that the first outlet 13 is also equipped with a louver that automatically changes the flow of air, and the second outlet 14 is on the indoor wall side. If the louver 19 of the second outlet 14
The movement of the louver of the first air outlet may be stopped so that the louver of the first air outlet does not move.

(G) Effects of the Invention As described above, the air conditioner of the present invention has a plurality of elongated air outlets parallel to the wall of the room, fixes the direction of the wind blown out from the air outlets on the wall, and Since the direction of the air blown out from the center side air outlet is automatically changed vertically, the air blown out from this center side air outlet can easily spread to the center of the room, and the indoor By reducing temperature unevenness, it is possible to reduce the difference in perceived temperature throughout the vicinity of the floor surface.
