detailed description

A first object of the present invention is to provide an indoor unit, the structural design of the indoor unit can effectively solve the problem of thicker indoor unit, and a second object of the present invention is to provide an air conditioner including the indoor unit. Device.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Referring to FIG. 1 to FIG. 4, the indoor unit provided by the embodiment of the present invention has an air inlet opening, and a grille is arranged at the air inlet, the grille covers the air inlet, and the wind enters the indoor unit through the grille, and the focus is on the air inlet. The upper edge is located at the top of the indoor unit, and the lower edge of the air inlet is located at the front side of the indoor unit. That is, the upper edge of the air inlet is higher than the lower edge, and the projected area of the air inlet on the vertical plane parallel to the rear panel of the indoor unit is greater than zero. The indoor unit rear panel refers to the panel that is attached to the wall. In this way, part of the air inlet is located at the top of the indoor unit, and the other part is located at the front side of the indoor unit. The wind can enter the indoor unit from the top of the indoor unit, or enter the indoor unit from the front side of the indoor unit to ensure the indoor unit. The wind area further avoids the case where the thickness of the indoor unit is thicker to increase the air inlet area.

In order to further optimize the above technical solution, the grille may be a curved grille 3, that is, the outermost sides of the grille ribs are all located on the same arc surface. The concave side of the curved grille 3 faces the interior of the indoor unit and extends along the arc from the upper edge to the lower edge of the grille. The upper edge of the grille is connected to the upper edge of the air inlet, and the lower edge of the grille is connected to the lower edge of the air inlet, that is, the upper edge of the curved grille 3 can be connected to the top plate 4, and the lower edge of the curved grille 3 can be Connected to the front panel 1. This makes the indoor unit look more beautiful. Of course, the grille may also be a straight-plate type grille, which is not limited herein.

Further, the grille may include a plurality of arcuate ribs 3a arranged along the left and right direction of the indoor unit, and a partition air inlet is formed between the adjacent two arcuate ribs 3a. The left-right direction of the indoor unit is a horizontal direction from the left side to the right side of the indoor unit. This makes it easier to connect the plurality of curved ribs 3a, and the plurality of curved ribs 3a are arranged in parallel with each other. Of course, the grid may also include a plurality of straight ribs arranged along the arc from top to bottom, which are not limited herein.

In order to prevent large objects from falling into the interior of the indoor unit, the ventilation area of the divided air inlets can be gradually reduced along the air inlet direction. In this way, the ventilation area on the air inlet side of the air inlet is larger to facilitate the air intake, and the ventilation area on the air outlet side is smaller, which can prevent large objects from entering. Further, the curved rib 3a has a trapezoidal cross section, that is, the curved rib 3a is cut along a plane parallel to the air inlet direction to obtain a trapezoidal cross section. Of course, the cross-section of the curved ribs 3a may also be a triangle or the like, which is not limited herein.

Similarly, when the grille has other shapes, the grille includes a plurality of ribs, and the adjacent two ribs form a split air inlet, and the ventilation area of the split air inlet gradually decreases along the air inlet direction. In this way, the ventilation area on the air inlet side of the air inlet is larger to facilitate the air intake, and the ventilation area on the air outlet side is smaller, which can prevent large objects from entering.

In addition, the grid may also be an L-shaped grid comprising a first side and a second side that are perpendicular and fixedly connected to each other. The first branch side is connected to the upper edge of the air inlet, and the second side is connected to the lower edge of the air inlet.

In order to further increase the air inlet area, a secondary air inlet can be opened on the lower side of the air inlet, and the secondary air inlet is opposite to the heat exchanger 5U type tube of the indoor unit, thus ensuring that the windward side of the heat exchanger 5 is not Occlusion. A secondary grille 2 is also provided at the secondary air inlet.

Based on the indoor unit provided in the above embodiment, the present invention also provides an air conditioner comprising any of the above-described embodiments. Since the air conditioner employs the indoor unit in the above embodiment, the advantageous effects of the air conditioner refer to the above embodiment.

The various embodiments in the present specification are described in a progressive manner, and each embodiment focuses on differences from other embodiments, and the same similar parts between the various embodiments may be referred to each other.

The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments are obvious to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but the scope of the invention is to be accorded
