Benefits of technology

[0018] Another object of the present invention is to provide an air conditioner having a reduced thickness and thus occupying a small space.
[0019] A further another object of the present invention is to provide a slim-type air conditioner having a heat exchanger installed on its entire surface and thus increasing an installation area of the heat exchanger.
[0020] A still further another object of the present invention is to provide a slim-type air conditioner that discharges cooled or warmed air uniformly through the entire surface of its indoor unit into an indoor space, thereby providing a more-pleasant indoor environment.

Problems solved by technology

The related art indoor unit essentially has the built-in blowing fan and thus has a drawback in that its size and thickness are increased.
Also, the related art indoor unit discharges air only through the limited air outlet hole and thus does harm to a person near to a position to which the discharged air is directed.

first embodiment

[0047]FIG. 2 is a cut-away perspective view of a slim-type air conditioner according to a first embodiment of the present invention.

[0048] Referring to FIG. 2, a slim-type air conditioner 200 includes an indoor unit case 201, a heat exchanger 211 disposed at the inner front of the case 201, a blower 209 reciprocating in a straight line behind the heat exchanger 211 to thereby suck external air and discharge the sucked air through the heat exchanger 211, and an outlet grill 213 disposed on a front surface of the case 201.

[0049] An inlet grill 203 is formed on a side surface of the case 201 so as to communicate with a space in which the blower 209 is installed.

[0050] The blower 209 includes a plate 205 reciprocating in a straight line behind the heat exchanger 211, and a guide value 207 forming a closed space in association with the plate 205 having moved to the front side.

[0051]FIG. 3 is an exploded perspective view illustrating a blower and a heat exchanger and a drain pan of th...

second embodiment

[0079] A second embodiment is identical to the first embodiment with the exception of an installation structure of the piezoelectric device.

[0080]FIG. 10 is a view illustrating a relationship between a plate and a piezoelectric device according to the second embodiment of the present invention.

[0081] Referring to FIG. 10, the second embodiment is characterized in that two or more piezoelectric devices 231 reciprocate the plate 205 in a straight line.

[0082] In detail, an electrode 232 is installed at an end portion of the piezoelectric device 231. When power is supplied to the electrode 232, the piezoelectric device 232 vibrates. Here, one end portion of the piezoelectric device 232 is fixed to a specific portion (for example, the rear cover 202) in the slim-type air conditioner, and the other end portion thereof is fixed to an outer end portion of the plate 205. When power is applied to the piezoelectric device 231, the piezoelectric device 231 vibrates back and forth, whereby th...

third embodiment

[0085] A third embodiment is identical to the first embodiment with the exception of a vibration structure of the plate.

[0086]FIGS. 11 and 12 schematically illustrate a driving unit for the plate according to a third embodiment of the present invention. In detail, FIG. 11 illustrates a state where the plate is moved to the front side by the driving unit, and FIG. 12 illustrates a state where the plate is moved to the rear side by the driving unit.

[0087] Referring to FIGS. 11 and 12, the inventive driving unit for the plate 205 includes a short L-shaped link 331, a long L-shaped link 332, and a link axis 333.

[0088] The short link 331 is connected to a motor so as to be able to reciprocate in a circular line of a specific radius. Also, a crank axis may be further provided between the motor and the short link 331. In this case, the motor need not rotate clockwise and counterclockwise. That is, the crank axis reciprocates in a straight line by the unidirectional (clockwise or counter...

Abstract

A slim-type air conditioner is provided. The slim-type air conditioner blows air by a plate reciprocating back and forth. Accordingly, the air can be discharged through a wide outlet hole, and the size and thickness of the air conditioner can be reduced. Therefore, the convenience of users and installers can be improved.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an air conditioner, and more particularly, to a slim-type air conditioner having an improved structure by which its internal blower can be slimy installed therein and thus it can be installed on a narrow wall surface, thereby making it possible to provide a beautiful external environment. [0003] 2. Description of the Related Art [0004] An air conditioner is a device for maintaining indoor air at a pleasant state by circulating air in association with a cooling cycle. In general, the air conditioner includes an indoor unit and an outdoor unit, and is classified into a combination-type air conditioner in which the indoor and outdoor units are integrally formed and a separate-type air conditioner in which the indoor and outdoor units are separately formed. [0005] A typical example of the combination-type air conditioner is a window-type air conditioner, and typical examples of the separ...
