Description

Air conditioner with outlet door

The present invention relates to an air conditioner, and more particularly, to an air conditioner having a discharge port door to prevent foreign substances from flowing through the discharge port when the air conditioner is not used.

In general, an air conditioner includes a compressor, a condenser, an evaporator, and the like to cool or heat the supplied air to supply the room.

6 is a perspective view of a conventional window air conditioner, which is a kind of air conditioner. As shown in this figure, the window air conditioner has a rectangular cylindrical outer casing 170, the compressor, condenser, evaporator, etc. constituting the refrigeration system is built in the outer casing 170. The front cover 200 having the inlet 140 and the outlet 120 of the air to be treated are attached to the front of the outer casing 170. When the compressor is operated by power supply, the indoor air introduced through the suction port 140 is cooled by the evaporator and is supplied to the room through the discharge port 150.

However, in such an air conditioner such as a window air conditioner, since the discharge port is always open, dust or foreign matter in the indoor air may be introduced into the interior through the discharge port when the operation of the device is stopped. Such dust and the like may accumulate on the surface of the evaporator or condenser inside the air conditioner and may reduce heat exchange efficiency and other functions of the operating unit.

In addition, in general, since the inlet and the outlet are adjacent to each other, part of the treated air from the outlet can be directly returned to the inlet, thereby lowering the overall efficiency of the air conditioner.

Accordingly, it is an object of the present invention to provide an air conditioner that can prevent dust and other foreign matter from entering through a discharge port and maintain the performance and reliability of a product.

Another object of the present invention is to provide an air conditioner capable of preventing the air discharged through the discharge port from being returned to the inside through the adjacent suction port.

According to the present invention, in the air conditioner having the discharge port of the treated air, a pair of discharge ports which are rotatably installed on the hinge portions provided opposite to both sides of the discharge port to rotate and open and close the front surface of the discharge port. It is achieved by an air conditioner comprising a door.

Here, the hinge portion may be simply configured as a hinge projection protruding up and down along the hinge axis on one side of the discharge port door, and a projection accommodation portion formed in the discharge port region to rotatably receive the hinge projection. In addition, the protrusion receiving portion may be formed so that the guide groove for allowing the front and rear movement of the hinge protrusion to communicate with each other so that the discharge port door can slide in and out of the discharge hole. In addition, the hinge protrusion preferably has a hinge head for preventing the departure from the guide groove. Here, the hinge portion of any one of the plurality of discharge ports is preferably formed between the suction port for sucking indoor air and the discharge port.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is an exploded perspective view of a window air conditioner according to the present invention. As shown in this figure, the window air conditioner has a rectangular cylindrical outer casing 70, and inside the outer casing 70, a compressor 60, a condenser 61 and an evaporator 62 constituting a refrigeration system. Is built in. In addition, the front cover 100 is attached to the front of the outer casing (70). An inlet 40 is formed at the left side of the front cover 100 to allow the air to be treated to be sucked into the air conditioner, and a discharge port having a plurality of horizontal blades 30 fastened to the upper right side of the front cover 100. 20) is formed so that the treated air is discharged in a constant direction. When the power is supplied, the refrigerant passes through the compressor 60, the condenser 61, the evaporator 62, and the like to generate cold air, and the generated cold air is supplied to the room through the discharge port 20 by the blower fan. In addition, the first discharge port door 10 and the second discharge port door 11 are formed on the left and right sides of the discharge port 20, so that the discharge port 20 can be opened and closed.

2 is a perspective view of the first discharge port door 10, and FIG. 3 is a perspective view of the discharge port 20. As shown in these figures, a hinge projection 12 is formed at one side of the upper and lower ends of the first discharge door 10, and the body 12a of the hinge protrusion 12 is formed at the free end of the hinge protrusion 12. As shown in FIG. It has a hinge head 12b having a larger wide cross section. In addition, a door handle 15 recessed in the right edge of the first discharge door 10 is formed to facilitate manual rotation. The second discharge door 11 has a shape similar to the first discharge door 10, the left and right width is narrower than the first discharge door (10).

The discharge port 20 has a rectangular cylinder shape, and a plurality of horizontal blades 30 are installed in parallel in the vertical direction so as to adjust the vertical direction of the discharged air. In addition, on the left and right sides of the upper and lower surfaces of the discharge port 20, the projection receiving portion 21, which can receive and rotate the hinge protrusions 12 of the respective discharge port doors 10 and 11, and the respective discharge port doors 10 and 11, are inside. Guide grooves 22 are formed in the front-rear direction so as to guide them. In addition, partition walls 24 are provided inside the left and right surfaces of the discharge ports 20 to form receiving slots 26 for accommodating the respective discharge port doors 10 and 11, Prevent random left and right rotation.

4 and 5 are perspective views showing the operation of the first and second discharge port doors 10 and 11 installed in the discharge port 20. As shown in these figures, the hinge protrusions 12 formed in the respective discharge port doors 10 and 11 are accommodated in the protrusion receiving portion 21, so that the first and second discharge doors 10 and 11 are rotated left and right. The discharge port 20 may be opened or closed and may be inserted rearward after being opened. The second discharge door 11 has a narrower left and right width than the first discharge door 10 and may be inserted rearward after being opened. The first discharge door 10 may be completely rearward after opening according to a user's selection. The thermal efficiency can be improved by preventing the air, which is inserted or properly projected toward the front, from being discharged through the discharge port 20 back to the suction port.

As such, when the air conditioner is not used, each of the discharge port doors 10 and 11 is closed by the operation described above to prevent dust or other foreign matter from being introduced into the air conditioner through the discharge port 20. Can be.

On the other hand, the hinge protrusion 12 and the guide groove 22 described above may be formed of another type of hinge protrusion or guide groove that can perform the hinge area, and in addition to the guide groove to form an auxiliary groove and discharge port A plurality of auxiliary protrusions may be formed at upper and lower ends of the door at a predetermined distance along the longitudinal direction so that the discharge port doors can be inserted in multiple stages. In addition, a latch device may be provided so that the discharge doors may be locked and rotated, and the handles may be protruded so that the discharge doors may be easily inserted and pulled out.

As described above, according to the present invention, the performance and reliability of the product can be maintained by preventing the inflow of dust and other foreign substances through the discharge port, and additionally, the air discharged through the discharge port is adjacent to the inlet port. There is provided an air conditioner which can increase the thermal efficiency by preventing the return to the inside.
