Description

TECHNICAL FIELD

The present invention relates to an air conditioner. Although the present invention is suitable for a wide scope of applications, it is particularly suitable for performing efficient heat exchange of indoor air in a manner that a front panel covering a whole front side of a front frame by moving back and forth opens/closes a plurality of inlets passages, blowing the heat-exchanged air upward and downward by reducing passage resistance, and providing an elegant exterior of the air conditioner.

BACKGROUND ART

Generally, an air conditioner cools or heats an indoor room to provide a user with a more pleasant indoor environment using a refrigerant cooling cycle including a compressor, a 4-way valve, an outdoor heat exchanger, an expansion mechanism, and an indoor heat exchanger. And, the above-configured air conditioner can be classified into a separate type and a single body type.
The separate type air conditioner and the single body type air conditioner are functionally equal to each other. In particular, the separate type air conditioner includes an indoor unit having a cooling and radiating device, an indoor fan, and an indoor fan motor and an outdoor unit having a radiating/cooling device, an outdoor fan, and an outdoor fan motor. And, the indoor and outdoor units separate from each other are connected together via a refrigerant pipe. Yet, the single body type air conditioner integrates the cooling and radiating functions and is directly installed at a hole or window of a house wall.
FIG. 15 is an exploded perspective diagram of an air conditioner according to a related art. And, FIG. 16 is a cross-sectional diagram of an assembled air conditioner according to a related art.
Referring to FIG. 15 and FIG. 16, an air conditioner according to a related art consists of a case 102, a front grill 110 assembled to a front side of the case 102 to have an air inlet 104, a top inlet grill 106, and an air outlet 108 provided to a lower front side or bottom of the front grill 110, a side inlet grill 112 rotatably connected to a front side of the front grill 110, a motor 114 loaded in the case 102, a blowing fan 116 connected to the motor 114, and a heat exchanger 118 provided between the blowing fan 116, the air inlet 104, and the top inlet grill 106.
The front air inlet 104 is provided to the front side of the front grill 110. The top inlet grill 106 is built in one body of a topside of the front grill 110. And, a pre-filter 105 is provided to the front grill 110 to filter off particles from the air sucked into the front air inlet 104.
The side inlet grill 112 is provided to protect the front air inlet 104 and the pre-filter 105. And, an upper part of the side inlet grill 112 is rotatably connected to an upper part of the front grill 110.
An outlet grill 124, which is provided with a condensed water receiving part 119 receiving a condensed water failing from the indoor heat exchanger 118 and includes a louver 120 changing a right/left wind direction of an air blown out of the air outlet 108 and a vane 122 changing an up/down wind direction, is loaded in a lower part within the front grill 110.
In the above-configured air conditioner, if the blowing fan 116 is rotated by a drive of the motor 114, an indoor air in front of the side inlet grill 112 sequentially passes through the side inlet grill 112 and the front air inlet 104 to filter off particles by the filter 105 and is then sucked into a space between the front grill 110 and the case 102.
And, the indoor air above the front grill 110 passes through the top inlet grill 106 and is then sucked into the space between the front grill 110 and the case 102.
The indoor air sucked in the above manner passes through the indoor heat exchanger 118 to be cooled or heated by the refrigerant flowing though the indoor heat exchange 118, keeps passing through the blowing fan 116, and is then blown into an indoor space via the air outlet 108 by being guided by the louver 120 and the vane 122.
However, the related art air conditioner has the following problem.
First of all, air in an indoor space is sucked into the related art sir conditioner via the front and top sides of the air conditioner, cooled/heated by the heat exchanger 118, and then blown into the indoor space via a bottom side of the air conditioner. If an installation height of the air conditioner is low, it takes a considerably long time for the cool air to expand all over the indoor space in a cooling operation mode. If the installation height is high, the heated air is blown to a user's face in a heating operation mode to raise unpleasantness.

Alternatively, at least three front panels 400 can be vertically or horizontally provided. And, it is apparent that the air outlet 620 can be selectively provided to the topside or the bottom side of the case 200.
In the present invention, the inlet passage 700 means a passage via which an air of an indoor space in front of the air inlet 320 is introduced into the air conditioner in order for the front panel 400, which is moving forward, to introduce the air of the indoor space into the case 200 via the air inlet 320.
The inlet passage 700 is provided to a space between the front frame 300 and the front panel 400. Since the front panels 400 are plurally provided, the inlet passages 700 are plurally provided in correspondence to forward/backward movements of the front panels 400.
Specifically, according to one embodiment of the present invention, if a pair of the front panels 400 are provided to be vertically spaced from each other centering on the display unit 310 in-between, the inlet passages 700 are provided to a middle part, an upper part, and a lower part of the space between the case 200 and the front panels 400 in correspondence to the movements of the front panels 400, respectively.
In particular, the inlet passages 700 are configured in a manner of diverging from the middle part of the space between the case 200 and the front panels 400 toward the upper and lower parts of the space. So, it is able to introduce a sufficient quantity of the indoor air to a space between the front panels 400.
In more particular, the inlet passages 700 are configured to diverge upward and downward across the whole middle part (left end to right end) of the space between the case and the front panels 400 in correspondence to the movements of the front panels 400 and across the whole upper and lower parts (left end to right end) of the case 200.
In this case, both lateral sides of the space between the case 200 and the front panel 400 are preferably closed in case of a forward movement of the front panel 400.
According to another embodiment of the present invention, in case that a pair of the front panels 400 are provided to be horizontally spaced apart from each other, the inlet passage 700 can be provided to a middle part and a lateral part of the space between the case 200 and the front panel 400 in correspondence to a forward/backward movement of the front panel 400.
In the present invention, the heat exchange passage 800 means a passage that induces heat exchange of an indoor air, which has been introduced into the case 200 via the inlet passage 700 and then passes through the heat exchanger 210 provided within the case 200.
If the front panel 400 moves forward to open the inlet passage 700, the heat exchange passage 800 is configured by the front frame 300 in rear of the air inlet 320 and the case 200.
In particular, in the heat exchange passage 800, the heat exchanger 210 is vertically installed and the middle part of the heat exchanger 210 has the prescribed shape. So, the heat-exchanged air having been introduced from the front can be smoothly blown in upward and downward slant directions.
Meanwhile, in the present invention, the outlet passage 900 means a passage to blow the air, which has been air-conditioned via the heat exchange passage 800, into the indoor space again.
The outlet passage 900 is opened/closed by the outlet unit 600 provided to the upper and lower parts of the case 200. And, the outlet passage 900 is configured by the air outlet 620 constructed with the front frame 300 and the case 200 assembled together.
In the present invention, the board type reinforcing rib 1300 without the frame-removing space, as shown in FIG. 10 and FIG. 11, is molded in one body of the front panel 400 along the backside of the front panel 400. In particular, the reinforcing rib 1300 is molded using an injection mold having a cavity for providing a space corresponding to the reinforcing rib 1300 and an injector having the injection mold loaded therein to inject a resin into the cavity.
For this injection, a plastic based resin is melted and then injected into the cavity via a resin entrance provided to the injection mold. By the injection molding, the reinforcing rib 1300 is molded in one body of the front panel 400. Hence, it is able to obtain rigidity invulnerable to transformation after completion of a product such as a panel molded without providing a separate frame-removing space.
Preferably, the frame-removing space free reinforcing rib 1300 is attached horizontally long along an upper part, a middle part and a lower part of the front panel 400 to reinforce the rigidity of the front panel 400 sufficiently. Preferably, the reinforcing rib 1300 is attached to extend to both of the bent lateral sides of the front panel 400.
In addition to the reinforcing rib 1300, to reinforce the rigidity of the front panel 400, a plurality of reinforcing pieces 1310 vertically spaced apart from each other can be molded in one body of the front panel 400 to be projected from both of the bent lateral sides of the front panel 400.
In the present invention, the frame-removing space free reinforcing rib 1300 is attached to the air conditioner. Yet, it is a mater of course that the reinforcing rib 1300 is applicable to various electronic products having movable panels.
In the present invention, as shown in FIG. 12 and FIG. 13, in addition to a control box cover 1500 provided with a terminal block 1510 loaded in the case 200 to be connected to various cables C, a block cover 1520 covering the control box cover 1500 is provided for fire prevention to be detachably loaded in the control box cover 1500.
A lower side of the block cover 1520 is open to accommodate the terminal block 1510. And, a space corresponding to the terminal block 150 is formed within the block cover 1520.
A pair of perforated insertion holes 1530 are provided to one side of the control box cover 1500 to be vertically spaced apart from each other. And, a pair of locking projections 1540 are projected from one side of a rim of a lower surface of the block cover 1520 corresponding to the insertion holes 1530 to be inserted in the insertion holes 1530, respectively.
To enable both of the control box cover 1500 and the block cover 1520 to be strongly assembled together, a block hook part 1550 held by an end portion of the control box cover 1500 is provided to the other side of the rim of the lower surface of the block cover 1520.
And, locking holes 1560 and 1570 are formed at one sides of the control box cover 1500 and the block cover 1520 by cutting corresponding portions of the covers 1500 and 1520 to prevent the separation of the block cover 1520 by inserting a locking means such as a screw and the like into the locking holes 1560 and 1570.
An aligning hole 1580 is formed parallel with the locking hole 1560 by perforating the control box cover 1500. And, an aligning projection 1585 is projected from one side of the block cover 1520 to correspond to the aligning hole 1570. So, the aligning projection 1585 is inserted in the aligning hole 1580.
Preferably, metal covers 1590 and 1595 are further provided to surfaces of the control box cover 1550 and the block cover 1520, respectively to enhance the fire prevention.
The block cover 1520 is assembled to the control box cover 1500 in a manner of inserting the locking projection 1540 of the block cover 1520 in the insertion hole 1530 of the control box cover 1500 and then inserting the aligning projection 1585 of the block cover 1520 in the aligning hole 1580 of the control box cover 1500.
After the block cover 1520 has been correctly posed on the control box cover 1550, the block hook part 1550 of the block cover 1520 is hooked on one side end portion of the control box cover 1500. If so, it is difficult for the block cover 1520 to be separated from the control box cover 1500.
As mentioned in the above description, if the block cover 1520 is correctly posed on the control box cover 1550, the control box cover locking hole 1560 and the block cover locking hole 1570 are naturally aligned together. So, it is able to fix the block cover 1520 to the control box cover 1500 more securely using the locking means such as the screw and the like.
A cable aligning hole 1600, as shown in FIG. 14, is provided to one side of the control box cover 1500 to enable various cables C connected to the terminal block 1510 to pass through. The cable aligning hole 1600 is cut and open in a vertical direction. And, the cable aligning hole 1600 is fixed to penetrate the case 200.
For this, a cable insertion hole 285 is formed at the case 200 by perforating a portion of the case 200 corresponding to the cable aligning hole 1600. Preferably, the cable insertion hole 285 is preferably configured to have its rim projected to enable the cable aligning hole 1600 to be quickly loaded in a correct position.
The cable aligning hole 1600 is preferably molded in one body of the control box cover 1500 for manufacturing convenience and rigidity security.
An extended front end portion of the cable aligning hole 1600 is cut backward in a vertical direction to configure a cable hanging part 1610. So, various cables passing through the cable aligning hole 1600 or various cables extended from various parts loaded in the case 200 such as a motor and the like can be hung on the cable hanging part 1610.
A cable fitting part 1620 is extended from an outer circumference of the cable aligning hole 1600 and is then bent backward. So, an extra cable can be wound on the cable fitting part 1620 to be fitted therein.

In this case, when the front panels 400 are moved forward, a plurality of the inlet passages 700 provided to the space between the front panels 400 and the front frame 300 play a role as a passage for introducing the indoor air into the air inlet 320.
So, since a plurality of the inlet passages 700 are opened/closed by the movements of the separated front panels 400, it is able to air-condition a sufficient quantity of the indoor air. By moving a plurality of the front panels 400 back and forth selectively, it is able to efficiently control the passages in various modes including a heating mode, a cooling mode, and other modes (sleeping mode, leaving-house mode, etc.).
Specifically, since the driving unit 500 includes the pinion gear 521 and the rack rail 522 connected to the front panel 400, the front panel 40 can be stably moved back and forth without fluctuation despite the intake flowing of the air.
In case that the indoor air introduced via the inlet passage 700 in front of the case 200 is discharged via the air outlets 620 provided to the top and bottom of the case 200, even spreading of the blown air can be induced without limitation put on the installation height of the air conditioner in case of the cooling/heating operation.
Meanwhile, if the central part of the heat exchanger 210 provided within the case 200 configures a prescribed shape, the intake indoor air can be more smoothly blown out in upward and downward directions owing to the reduced flowing resistance within the heat exchange passage 800.
Moreover, the outlet panel 610 is rotationally moved toward a front/rear of the case 200 to open/close the outlet passage 900. So, the outlet panel 610 can remove the user's unpleasantness by indirectly blowing warm air without interrupting front air introduction in case of heating operation.
Besides, the frame-moving space free panel type reinforcing rib 1300 and the reinforcing pieces 1310 are attached to or molded in one body of the front panel 400. So, the front panel 400 can be conveniently manufactured. And, sufficient rigidity can be secured to prevent transformation due to contraction.
The control box cover 1550 and the block cover 1520 are conveniently assembled to the case 200 and the control box cover 1500, respectively. And, the block cover 1520 cuts off the terminal block 1510 from an external environment to prevent a fire being set by an overheating of the terminal block 1510.
Various cables pass through the cable aligning hole 1600 provided to the control box cover 1500 to be bound to the terminal block 1510. So, the arrangement of the cables are convenient. And, a pair of the cable aligning hole 1660 and the cable insertion hole 285, a pair of the position aligning projection 1585 and the position aligning hole 290, and a pair of the block hook part 1550 and the case hook part 295, which are correspondingly provided to the control box cover 1500 and the case 200, respectively, enable the control box cover 1500 to be correctly and quickly aligned and fixed to the case 200.
