[Action]

By making the air conditioner thin (for example, 200 mm or less in depth), the presence in an air-conditioned room (living room) or the presence outside the room can be reduced. In addition, bring the front panel of the air-conditioning unit close to the entire area of the front of the unit, and coordinate the panel with the room, etc. (for example, apply the same wallpaper as the room, paint the same color as the room or exterior wall, etc.) Can be. The only place where the air-conditioning unit stands out is only the air inlet / outlet. By forming the air inlet / outlet into a slit at the lateral corner or at the top and bottom, the presence of the air-conditioning unit can be reduced.

In the air-conditioning unit structure as described above, in order to improve comfort, a plurality of air outlets may be provided, and the air flow may be controlled. For example, two outlets are provided on each side of the unit (left and right (horizontal direction), for a total of four locations). It will not cause any discomfort. In addition, since the suction port is also provided in the left and right direction of the unit, even if the person to be air-conditioned is right before the unit, the airflow from the unit does not directly hit the person to be air-conditioned. During the heating operation, warm air is blown out from the lower slit outlets on the left and right sides of the air conditioning unit, so that the warm air warms the entire room through the wall and reaches the upper part. In this case, a further effect can be obtained by providing a guide plate or the like in the unit blowing section so that the blowing airflow does not directly hit the person to be air-conditioned. In addition, by automatically swinging the guide plate, the blown air current swings, and the temperature distribution in the living room can be made uniform to further improve comfort.

〔Example〕

In order to make the unit structure easy to fit into the interior of the room to be air-conditioned, the unit should be thin (depth dimension), the unit front panel should be large, and the air inlet and outlet should be around the panel. In order to improve comfort, a plurality of air outlets are provided so that the person to be air-conditioned can select the air outlet direction. Further, the outlet is elongated in the vertical direction of the chamber. Thereby, the possibility that the airflow blown out from the air conditioner directly hits the person to be air-conditioned can be reduced, and the comfort is improved.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an external view of an indoor air conditioning unit of the present invention,
FIG. 2 is an internal structural view of the unit shown in FIG. 1 when the front cover 1 is removed, FIG. 3 is a cross-sectional view of the air conditioning unit shown in FIG. 1, and FIG. Heat exchanger 7 shown
FIG.

As shown in these figures, in the indoor air-conditioning unit, a square-shaped heat exchanger 7 as shown in FIG.
Is provided, and a dehumidification water (drain) receiver 8 is provided immediately below the water supply. The blowers 92 and 93 are installed above and below the heat exchanger 7. This blower casing 92
Numerals 1 and 931 each have a two-way blowing structure in which air is sucked in from the left and right directions (lateral directions) at the center in the vertical direction of the front cover 1 and blows out in the left and right directions at the upper and lower parts of the unit. A blower 9 is located below the unit upper outlet 3.
An operation panel 4 for controlling the units 2, 93 and the entire unit is provided, and a shielding plate 5 is disposed at the top and bottom of the unit, and between the air suction part and the air discharge part. The shielding plate 5 prevents the airflow blown out of the unit from being directly sucked from the suction portion, thereby preventing the efficiency of the air conditioner from decreasing.

With the air-conditioning unit structure described above, there is no air inlet / outlet in front of the air-conditioning unit, and as a result, the front panel can be coordinated with a color or wallpaper suitable for the living room. Therefore, even if the air conditioner of the present embodiment is installed in any room, an air conditioner having no strange feeling can be obtained. In addition, as shown in Fig. 5, if the air conditioner is more suitable for the room, it should be embedded in the wall, and the size of the air conditioner that protrudes from the wall should be about 0 to 50mm. Feeling can be further reduced. Further, by attaching another piece 13 to the upper part of the unit, its presence can be further reduced.

Next, the flow of air in the air conditioning unit will be described. The indoor air is drawn by the blowers 92 and 93 and enters the unit from the left and right suction ports 2 of the unit. Thereafter, the air passes through the heat exchanger 7 and exchanges heat with the refrigerant in the heat exchanger and is cooled (during cooling operation). The air is sucked into the blower and blown into the room from the left and right outlets 3. In this case, blower 9
The airflow of 2,93 can be changed by the fan speed. Table 1 shows an example of the air volume setting.

As shown in this table, during the cooling operation, the air volume from the upper blower 92 is increased, and the air volume from the lower blower 93 is reduced. In addition, during the heating, contrary to the cooling, the airflow from the lower blower 93 is increased, and the airflow from the upper blower 92 is reduced.
Further, the blown airflow is adjusted by the vertical blades 31 and the horizontal blades 3 so that the person to be air-conditioned does not directly hit the cold and hot air, thereby causing discomfort. Here, by automatically swinging the vertical blades 31, the blown air current spreads throughout the room and comfort is increased. When the left and right heat loads of the air conditioning unit are different, the left and right air volumes can be adjusted by controlling the air flow direction plates 922 and 932 in the blower case. That is, if the right wind direction plate is formed as shown by the dotted line, the ventilation resistance of the wind direction plate increases, and the airflow to the right can be reduced.

As described above, according to the indoor air-conditioning unit structure, it is possible to freely change the air volume ratio in the upper, lower, left, and right directions, and at the same time,
The blowing airflow direction can also be freely changed. Therefore, air conditioning according to the situation of the room in which the air conditioner of this embodiment is installed can be performed, and comfortable living room conditions without discomfort can be obtained.

As described above, according to the present invention, the indoor air-conditioning unit can be coordinated with the living room, and the air intake and the air outlet are provided on the side of the air-conditioning unit. It has a thin shape and can be finished into an air-conditioning unit that matches the interior of the living room.

In addition, since a plurality of intakes and outlets are provided, it is possible to create an intake airflow and an airflow tailored to a person to be air-conditioned in the living room, and to blow the air to the side forward of the air conditioner. The heat exchanged air does not directly hit the person being air-conditioned,
Air flows from the wall side of the room so as to wrap around the center of the room, and air conditioning can be performed, thereby greatly improving comfort.

Note that the heat exchanger 7 in the indoor air-conditioning unit does not necessarily have to be <shaped, but may be shaped as ∧ or |.

6 and 7 show a part of the internal structure of the indoor air-conditioning unit shown in FIGS. 1 to 4. FIG. FIG. 6 is an internal structural view when the front cover of the unit is removed, and FIG. 7 is a cross sectional view of FIG. In this example, a heat exchanger 7 is provided at the center, and a one-way blower is provided above and below it. Air is sucked into the room air from the side of the unit as shown by an arrow 61, is sucked into upper and lower blowers in the unit, is discharged, and then cooled or heated through the heat exchanger 7, and is opposite to the suction side of the unit. It is blown into the room from the side of the side. During cooling, the guide blade 96 faces upward as shown by the solid line in the figure, and blows out cool air upward as shown by the arrow 62. Conversely, during heating, the air blows downward as shown by the broken line in the figure, and blows warm air downward. Further, the direction of air blowing is adjusted by the vertical blades 31 in the front-back direction.

In the example of FIG. 6, it is possible to make a unit in which the mounting direction and the mounting position of the blower 9 and the heat exchanger 7 are changed so that the air blowing direction is the opposite direction (left direction). As shown in (2), when two units having a symmetrical structure are combined and two units are installed with their suction ports close to each other, air can be blown out in both left and right directions, thereby improving comfort and capacity.

FIG. 9 shows still another example of the indoor air-conditioning unit 10 in which a reversible flow blower such as a once-through fan is provided above and below the unit, and a heat exchanger 7 is arranged beside the reversible flow blower. . Other configurations are almost the same as those of the above-described embodiment, and the same reference numerals are given and the description is omitted.

FIG. 10 shows an example in which the indoor air-conditioning unit 10 shown in FIG. 6 or 9 is used as an outdoor unit 10 '. The outdoor unit is mounted on the outer wall of the building at the veranda 15, and a compressor unit 14 is installed beside the outdoor unit 10 '. Since the air conditioner of the present invention can be made to have a thin structure, it does not become stuck even when installed on a veranda or the like, and since the front of the unit has a panel shape, the panel color is the same color as the wall or a color matching the surrounding color. And the presence or discomfort of the air conditioning unit can be eliminated. Further, in the outdoor unit, when strong wind blows from the direction of ejection from the unit, there are problems such as a decrease in the unit air volume and damage to an impeller of a blower. With respect to the wind 65 from the direction, there is no fear of a decrease in the air volume or damage to the impeller. The wind from the blow direction may cause a problem such as a decrease in the air volume.However, if the installation location is determined, the blow direction is also determined, so select the blow direction from the unit in consideration of the blow direction. do it. In the unit having the wind direction plates 922 and 932 like the unit shown in FIG. 2, the influence of the wind can be minimized by closing the wind direction plates in the direction in which the wind blows. Further, as shown in FIG. 11, if a guide plate 35 as shown is provided at the unit outlet in the direction in which the wind blows, the influence of the wind can be completely prevented. Since the unit shown in Fig. 9 can freely select the air blowing direction, it can be used by changing the blowing direction according to the direction of the wind. Even if there are houses, trees, pot plants, etc. near the unit, it can be used from the outdoor unit. The harmful effects of hot air can be prevented.

12 to 15 show another example in which the internal structure of the indoor air-conditioning unit 10 is changed. In this example, the air conditioning unit
Numeral 10 designates four vertical flow-through fans A1, A2, B1, and B2 on both sides of the vertical cabinet 16, and Juan A1, B1 and Juan A
Two fan driving motors 94 are provided between the motors 2 and B2. A <-shaped heat exchanger 7 is vertically installed corresponding to this fan. Heat exchangers 7 corresponding to each fan
On the opposite side, air inlets and outlets 50 and 51 are provided, and guide vanes 31 and 32 for controlling the air flow direction are installed at the air inlet and outlet. An operation panel 4 for controlling the air conditioning unit is mounted between the air inlets 50 and the air outlets 51. A partition plate 15 for separating the air flow from the heat exchanger to the fan inlet / outlet is provided at the middle between the upper and lower fans and at the upper and lower ends of the heat exchanger 7. In front of this air conditioning unit, there is a front cover 1 without air inlet / outlet.
Is installed. In FIG. 12, ducts 9 and 91 of another piece are installed above and below the main body of the air conditioning unit 10 for integration with the interior. In the air-conditioning unit structure of this embodiment, by coordinating the front panel with the interior of the living room, the presence of the air-conditioning unit is eliminated, which is effective for the interior of the living room. In this example, one fan motor 94 drives two flow-through fans A1 and A2, or two fans B1 and B2, but one motor may be attached to each fan. In this case, the direction of the air suction and the direction of the air blow can be selected more freely.

Next, the operation of the components of the air conditioning unit and the flow of air will be described. First, an example in which the flow direction of the air in the reversible flow once-through fan is switched will be described with reference to FIG. FIG.
2 shows a horizontal cross section of a fan section. Once-through fan 12 (A1, A
2, B1, B2) are always rotating in the direction of arrow 161. When the rotating case 173 attached to the rotating ring 172 is stationary at the position shown by the solid line in FIG.
0 is generated and the air flows in the direction of arrow 17 due to this flow. On the other hand, when the rotating case 173 is rotated by 180 ° by the rotating ring 172, the rotating case 173 moves to the position shown by the dotted line. As a result, a vortex in the fan is generated at 181 shown by a dotted line, and the airflow flows in the direction of arrow 17 shown by the dotted line. As described above, the direction of the air flow can be changed depending on the position of the rotary ring 172, and the air inlet / outlet 50 can be an air inlet or an outlet.

Next, the basic air flow during cooling operation
This will be described with reference to FIG. 13 and FIG. The rotating ring shown in FIG. 13 so that the air flow direction of the reversible once-through fans A2 and B2 on the lower side of the air conditioning unit is inside the unit, and the air flow direction of the upper reversible once-through fans A1 and B1 is outside (the living room side). Determine the position of 172. When the air-conditioning unit is operated in this state, the air in the living room is guided inside from both sides of the air-conditioning unit by two lower flow fans A2 and B2 as shown by arrows 17.

The air entering the unit from the left and right air inlets 50 passes through the heat exchanger 7 and exchanges heat with the refrigerant inside the heat exchanger and is cooled.
It reaches the upper part of the unit through the partition plate 15 in the center of the unit,
Then, the air flows into the living room as shown by arrow 17 from the entrance 51 through the upper reversible flow through fans A1 and B1 through the upper heat exchanger 7 while being separated in the left-right direction. The basic air flow during the heating operation is opposite to that for cooling, and
By adjusting the position of the rotating ring 172 in the direction in which the flow-through fans A2 and B2 blow out into the room, the air in the room is sucked in from the left and right sides of the upper part of the air-conditioning unit. Warm air can be blown from the left and right lateral directions at the bottom. In this way, it is possible to draw in the room air from the lower part of the air conditioning unit during the cooling operation and blow out the cool air from the upper part of the unit, and to draw in the room air from the upper part of the unit during the heating operation and to blow out the warm air from the lower part of the unit. In addition, since the outlet of the cold and hot air is in the vertical direction on both sides of the unit, the room is wrapped in the cold and hot air from the left and right sides.

The air flow direction is the basic type of cooling and heating, and it is possible to basically select eight types of suction and blowing modes as shown in Table 2 depending on the installation location of the equipment in the living room, the position of the person to be air-conditioned, and the like. it can. For example, regarding the form of V, FIG. 12 and FIG.
This will be described with reference to the drawings.

First, air suction ports are provided on both side surfaces of the separate piece ducts 9, 91 in FIG.

Adjust the rotating ring 172 in the direction in which the air-conditioning unit blows out all four reversible once-through fans 12 into the living room.
Accordingly, the air in the upper part of the room enters from both lateral directions of the duct of the upper separate piece 9 and is guided into the air conditioning unit 1, passes through the heat exchanger 7, and flows left and right from the lateral direction of the unit by the reversible flow through fans A 1 and B 1. It is blown out. The indoor air drawn by the lower reversible flow-through fans A2, B2 is sucked in from the lower separate duct 91, is guided into the air-conditioning unit, and is blown out from both lateral directions below the unit. By providing the passages to the heat exchanger 7 at the upper and lower portions of the air conditioning unit in this way, it is possible to form more suction and blow-out forms.

Although not shown in FIG. 14, only one fan out of the four fans blows out of the unit and the other three fans blow out of the unit. It is also possible to blow out the wind.

Thus, according to this example, since the outlet from the air conditioning unit has a vertically long shape on both sides of the unit,
The airflow that wraps the indoor space from both lateral directions can be generated by the cool and hot air, and the wide space can be air-conditioned by the cool and hot air flowing along the wall. In addition, since the most suitable form of suction and blow-off can be formed for the room depending on the room, the installation location of the equipment, the position of the person to be air-conditioned, etc., it is a comfortable space regardless of the room shape and layout. Can be obtained. In addition, since the front cover 1, the separate piece ducts 9 and 91 above and below the unit can be coordinated according to the living room, an effective air conditioner can be obtained even in the interior.

As described above, according to the present invention, the suction air outlet of the air-conditioning unit can be freely selected in accordance with the cooling operation or the heating operation and in consideration of the shape of the room to be air-conditioned, the installation location of the equipment, the position of the person to be air-conditioned, and the like. As a result, highly comfortable air conditioning can be achieved.

FIG. 16 is a view showing an example in which the air conditioning unit 10 shown in FIG. 12 is incorporated in a partition 80, and another piece 9 is inserted into the space from the air conditioning unit 10 to the ceiling 81. The lateral portion of the separate piece 9 forms an air port 52. Reference numeral 82 denotes a refrigerant pipe inlet / outlet, and reference numeral 83 denotes a drain pipe.

Next, an example of an air conditioner that can complete the installation work of the air conditioner, the interior work of the decorative board, and the decoration work at once will be described.

In order to obtain such an air conditioner, the decorative panel is divided into a decorative panel for the wall disposed at both ends and a decorative panel portion disposed at the center, and the decorative boards for the walls at both ends are divided into decorative panels on the wall. Attach and connect with the body of the air conditioner together with installation, while connecting the decorative panel in the center to the body of the air conditioner, and arrange the inlet and outlet of the air conditioner between the decorative board for walls and the decorative panel. Set up and configure.
