Description

Air conditioner having side discharge ports capable of front wind and side wind {Air Conditioner Having Side Discharge Ports Capable of Blowing both Front and Side Winds}

The present invention relates to an indoor unit of an air conditioner, and more specifically, to a side outlet for both front and side wind, which allows blowing both front and side winds without a front outlet or through a side outlet separately from the front outlet. It's about an air conditioner.

In general, an air conditioner is a device for comfortably adjusting indoor air conditions by performing a series of refrigerant cycles of compressing, condensing, expanding, and evaporating the refrigerant.

As an air conditioner, a separate type air conditioner is generally used in which a heat dissipating part with a condenser and a heat absorbing part with an evaporator are installed separately. At this time, the heat dissipating part is installed outdoors, so it is usually called an 'outdoor unit', and the heat absorbing part is installed in an air-conditioned space, that is, indoors, so it is called an 'indoor unit'.

Conventionally, as in Patent Documents 1 to 3, a form having a front discharge port on the front of the indoor unit and a side discharge port on the side has been known.

Indoor units of the type shown in Patent Documents 1 to 3 (hereinafter collectively referred to as 'air conditioners') are supplied to the front of the air conditioner through the front discharge port provided at the front of the air conditioner, depending on the user's operation or control settings. Air is discharged to the left and right sides of the air conditioner through the side discharge port provided on the side.

This type of air conditioner can evenly condition the room according to the user's needs by selecting or coordinating the discharge direction to the front and side.

However, this type of air conditioner must have a front outlet on the front of the air conditioner and a device to open and close the front outlet, which not only increases the production cost but also increases the freedom of design of the front of the air conditioner. There is a drawback that limits .

In addition, as in Patent Documents 4 to 5, a large discharge port is provided at the front center or both left and right sides of the air conditioner, and a wind direction control plate (or wind direction control flap) is installed at the discharge port to adjust the wind direction, or the discharge port itself A form of controlling the wind direction by controlling the direction of is also known.

However, this type of air conditioner must inevitably be equipped with a movement mechanism to move the discharge port or wind direction control plate, which not only increases production costs, but also requires that the movement mechanism be visually visible to the user from the outside of the air conditioner. It has the disadvantage of damaging the aesthetics of the air conditioner.
