Problems solved by technology

[0004] However, in the design process of air conditioners in the prior art, the setting position and direction of the blower fan are greatly restricted. In addition, in order to obtain a larger air volume, the volume of the blower fan will be increased accordingly, which is not conducive to the air conditioner. Miniaturized and slim design
[0005] In addition, the air inlet and outlet of the air conditioner in the prior art are all arranged on the front of the casing, so the efficiency of cooling / heating is low, and the time required for cooling / heating is relatively long.
[0006] Furthermore, the air conditioner of the prior art is not provided with a separate device for reducing the noise inside the casing, so it will produce a lot of noise

Embodiment Construction

[0046] Hereinafter, the indoor unit of the air conditioner of the present invention will be described in detail with reference to the accompanying drawings.

[0047] As shown in Fig. 1 and Fig. 2, the indoor unit of the air conditioner of the present invention comprises: the casing 10 that constitutes appearance, the heat exchanger 90 that is arranged on the inside of casing, the blower that makes the air inside casing flow forcibly and A flow regulating part that allows the air in the blower to flow smoothly. In order to reduce the overall size of the cabinet 10, the cabinet 10 is formed longer in the longitudinal direction. Although the casing 10 shown in the figure has a quadrangular end surface, the shape of the end surface of the casing 10 is not limited thereto, and the end surface may also be polygonal or circular.

[0048] A suction port 11 is formed on the lower part of the casing 10 , through which air enters the interior of the casing 10 . In order to facilitate t...

Abstract

The invention discloses an air conditioner, which comprises an indoor unit and an outdoor unit. The indoor unit comprises a casing that is longer in longitudinal direction; suction ports for sucking external air that are located at the two sides of the lower part of the casing; an exhaust port that is located at the upper part of the casing and discharges the heat-exchanged air in one direction; a blower that forces the sucked external air to flow toward the exhaust port, and a heat exchanger that is arranged at the lower part of the casing and makes the sucked air to exchange heat with the refrigerant. The length of the heat exchanger along the longitudinal direction of the casing is bigger than the length along the thickness direction. The indoor unit in the invention not only allows installation of a heat exchanger with a bigger heat-exchanging area, but also can minimize the overall size of the indoor unit.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an indoor unit of the air conditioner. Background technique [0002] Generally speaking, an air conditioner is a device for cooling and / or heating an indoor space by making a refrigerant perform a process of compression, condensation, expansion, and evaporation. Air conditioners are generally divided into ordinary one-drag one-type air conditioners and one-drag multi-type air conditioners; according to the cooling / heating methods, they can be divided into cooling-only air conditioners and heating and cooling air conditioners. [0003] An air conditioner usually includes a refrigeration cycle system consisting of a compressor, a condenser, an expansion valve, and an evaporator. The gaseous refrigerant compressed in the compressor flows into the condenser and becomes a liquid refrigerant. The refrigerant releases heat to the outside while undergoing a phase change on the condenser. After that...
