Description

[Detailed Description of the Invention] This invention relates to a wall-mounted indoor unit for air-conditioning and heating equipment, which has a small dimension in the height direction and has low internal air passage resistance.

FIG. 1 is a sectional view showing a conventional wall-mounted indoor unit for heating and cooling equipment. The unit body 1 includes an impeller 2, a blower A disposed in a fan casing 3 housing the impeller 2, and a heat exchanger 4. Indoor air is sucked in through an air suction port 5 opened in front of the lower heat exchanger 4, and the heat-exchanged air is sent indoors through a discharge port 6 opened in front of the upper blower A. has been done.

However, in the conventional indoor unit with the above configuration, the heat exchanger 4 is arranged vertically below the internal blower A, so the height dimension of this type of commercially available indoor unit is usually 350 mm.
m" is about 480 mm, which has caused the problem that it cannot be installed on a wall, especially in the current housing situation where ceilings are getting lower.

Taking this point into consideration, this idea was designed by configuring the indoor unit in a lateral shape, placing the blower approximately in the center of the horizontal part along the ceiling, and facing the blower to connect the heat exchanger and the air discharge into the room. By providing an outlet, the length of the vertical portion, that is, the dimension in the height direction of the unit body is reduced.An embodiment of the wall-mounted indoor unit of this invention will be described below.

That is, in FIG. 2, reference numeral 1 denotes a unit main body, which has a side profile as shown in the figure, and is composed of a horizontal portion 7 along the ceiling surface 13 and a vertical portion 8 along the mounting wall surface 12.

2 is an impeller similar to the above, and 3 is a fan casing that houses this impeller 2. These constitute a blower A arranged at the center of the horizontal section 7.

4 is a heat exchanger provided diagonally at the corner where the horizontal part 7 and the vertical part 8 meet; 5 is an air inlet 6 provided at the bottom of the vertical part 8; air outlet to, 9
is a drain receiver provided directly below the heat exchanger 4, and is provided inside the vertical portion 8 of the unit main body 1.

10 is a refrigerant pipe provided below this drain receiver, 11 is a drain pipe provided below this refrigerant pipe 10, and 12 is a wall surface on which the unit main body 1 is attached.

In the above configuration, when the blower A is driven, the indoor air taken in from the air suction port 5 of the unit body 1 enters the fan casing 3 where heat is exchanged with the heat exchanger 4, and the impeller 2 causes the indoor air to enter the fan casing 3 on the discharge side of the blower A. The air is discharged from the air discharge port 6 into the room located at.

Also, the dehumidified water adhering to the heat exchanger 4 during cooling operation is collected in the drain receiver 9 provided directly below it, and then passes through the drain pipe 11 provided below it provided inside the vertical portion 8 of the unit main body 1. It is discharged outside.

That is, in the case of this idea, it is located on the blower A in the center of the horizontal portion 7 of the unit 1, and the heat exchanger 4 on the inhalation side is performed, and the discharge side is also exhaled indoors. The outlets 6 are arranged so that they are all lined up in the horizontal direction, and the vertical part 8 is further provided with the refrigerant pipe 10, the drain pipe 11, and the air suction port 5, so the wall-mounted type has the same capacity as the conventional one. The height dimension of the indoor unit can be reduced to 173 to 1/2, and therefore it can be installed on a wall near the ceiling that has only a small height dimension.

Since the indoor unit of this invention is constructed as described above, the height dimension of the product can be significantly reduced, and therefore it is extremely suitable as a wall-mounted unit in modern rooms with low ceilings. Moreover, it also has the advantage that the resistance of the ventilation passage within the unit main body can be greatly reduced by forming the above-mentioned ventilation passage.
