The present invention relates to a blowout panel and an air conditioning indoor unit including the blowout panel.

BACKGROUND Conventionally, there is an air conditioning indoor unit having an indoor unit main body and a blowout panel. In the main body of the indoor unit, an axial fan is provided, the rotation axis of which extends along the vertical direction. The blowout panel is provided below the indoor unit body and has a blowout port. In the air outlet, a wind guide fin is provided.

In the above-described air conditioning indoor unit, in order to increase the blowout area of the air outlet and in consideration of the layout convenience, it is surrounded by a rectangular outer frame, a rectangular inner frame, an outer frame and an inner frame. It is conceivable to employ an outlet panel having a rectangular outlet formed.

However, in the case described above, since the air flow generated by the axial fan is difficult to go to the corner of the outlet, the blowing of the air from the outlet tends to be uneven.

In addition, there are also conventional air processing devices that send a spiral air flow sent out from the air blowing unit of the air processing device to the blowout panel via the air blow pipe by connecting the air blow pipe to the rectangular blowout panel. . Even in such a case, since the spiral air flow is less likely to go to the corners of the blowout panel, the blowout of the wind at the blowout port tends to be uneven.

In view of the above-mentioned problems, an object is to provide an air conditioning indoor unit including a blowout panel and a blowout panel which can realize blowout of wind over the entire 360 ° and make the blowout of the blowout air outlet uniform. .

In order to solve the above-mentioned technical problem, a blow-out panel has an outer frame, an inner frame, and a connecting rod. A multilateral outlet is formed by being surrounded by the outer frame and the inner frame. The connecting rod is provided at the corner of the outlet. The connecting rod connects the outer frame and the inner frame. The connecting rod has a connecting rod body and a connection. The connection portion is closer to the center of the blowout panel than the connection rod main body, and connects the connection rod main body to the inner frame. The connection portion and the connection rod body each have a first surface and a second surface. When viewed from the inner surface side to the outer surface side of the blowout panel, the first surface is located on the downstream side of the second surface in a direction around the center of the blowout panel clockwise. The second surface of the connection portion and the second surface of the connection rod body are combined to form a concave shape inward.

According to the blow-out panel of the above-mentioned structure, the blow-out panel utilizes a multilateral blowout port formed by being surrounded by the outer frame and the inner frame. Thereby, for example, when used for an air conditioning indoor unit including an indoor unit main body provided with an axial flow fan, wind can be blown out over the entire 360 ° circumference. Moreover, the blowing panel has a connection rod provided at the corner of the outlet. When viewed from the inner surface side to the outer surface side of the blowout panel, the second surface of the connection portion of the connection rod and the second surface of the connection rod main body are combined to form an inwardly recessed shape.

For convenience of explanation, three directions perpendicular to each other are defined as X direction, Y direction, and Z direction. Among them, the X direction and the Y direction correspond to the horizontal direction of the state in which the air conditioning indoor unit is actually attached. This corresponds to the vertical direction in the state where the air conditioning indoor unit is actually attached. The Y1 direction side, Y2 direction side, X1 direction side, X2 direction side, Z1 direction side, and Z2 direction side are the front side, rear side, left side, right side, lower side, with the air conditioning indoor unit actually attached. Correspond to the upper side.

As shown in FIG. 1, the air conditioning indoor unit 1 of the present embodiment has an indoor unit main body 10 and a blowout panel 20. An axial fan 30 is provided in the indoor unit body 10. The blowout panel 20 is provided below the indoor unit main body 10 (Z1 direction side).

Here, the indoor unit body 10 has a substantially rectangular parallelepiped shape as a whole, and has a top surface, a bottom surface, and four side surfaces. Intake ports JF are provided on all the side faces, and filter units 40 are provided on all the intake ports JF. Further, as shown in FIG. 1, a heat exchanger 50 is further provided in the indoor unit main body 10. The heat exchanger 50 is provided inside the air inlet JF and is surrounded by the filter unit 40. In addition, an axial fan 30 is provided inside the heat exchanger 50. The axial flow fan 30 is provided such that the rotation axis overlaps the central axis L of the blowout panel 20 (an axis extending through the center of the blowout panel 20 and extending in the thickness direction of the blowout panel 20). As shown in FIG. 2, at this time, the spiral air flow generated by the axial fan flows clockwise around the center of the blowout panel.

Further, as shown in FIGS. 1 and 2, the blowout panel 20 has an outer frame 21, an inner frame 22, and a connecting rod 24. A multilateral outlet CF is formed by being surrounded by the outer frame 21 and the inner frame 22. The connection rod 24 is provided at the corner of the blowout panel 20 and connects the outer frame 21 and the inner frame 22. As a result, it is not necessary to increase the number of other connecting members, and the disturbance that the other connecting members give to the air flow from the air outlet can be reduced, so that not only the structure is simple, but also the blowing area can be increased.
