Detailed ways

Hereinafter, preferred embodiments provided by the present invention will be described in detail with reference to the accompanying drawings.

According to the air conditioner provided by the preferred embodiment of the present invention, as shown in Figure 1, it includes a main body 10 forming an overall appearance, a front panel 11a arranged at the lower front part of the main body 10, and a front panel 11a arranged at the upper front part of the main body 10 and opened and closed by moving up and down. The up and down drive panel 11b of the front discharge port 15. Both sides of the lower part of the main body 10 are provided with suction grilles 12a for inhaling air, and both sides of the upper part of the main body 10 are provided with side outlets 13 for discharging air and automatic shutters 12b for opening and closing the side outlets 13 .

And, the lower part of the internal space of the main body 10 is provided with an exhaust fan (not shown), and the upper part of the internal space of the main body 10 is provided with a heat exchanger (not shown). The indoor air entering the main body 10 is subjected to heat exchange through the heat exchanger, and the heat-exchanged air is discharged into the room again through the outlets 13 and 15 .

A detachable pre-filter 16 is arranged inside the suction grille 12a to filter out large particles of dust in the air flowing in through the cracks 14 formed in the suction grille 12a, and a detachable electric dust collector is arranged in front of the exhaust fan 17, to filter out the fine dust in the air sucked by the exhaust fan.

When cleaning or replacing the pre-filter 16 and the electrostatic precipitator 17 arranged in the inside of the main body 10, in order to open and close the front panel 11a easily, and to make the front panel 11a and the main body 10 not interfere with each other when opening and closing the front panel 11a, A hinge 20 for hinge-connecting one side of the front panel 11a and one side of the main body 10 is provided.

The hinge 20 is composed of a lower hinge 20a provided on the lower part of the front panel 11a and an upper hinge 20b provided on the upper part of the front panel 11a. The lower hinge 20a and the upper hinge 20b are arranged vertically so that the front panel 11a opens and closes the main body 10 in the left-right direction. the front lower part.

Since the lower hinge 20a and the upper hinge 20b that hinge the front panel 11a to the main body 10 have basically the same structure, the lower hinge 20a will be described first, and the upper hinge 20b will only describe the structure different from the lower hinge 20a. In addition, the same reference numerals are assigned to the same components as those of the lower hinge 20a, and detailed description thereof will be omitted.

As shown in Figure 2, in order to hinge the front panel 11a to the main body 10, the lower hinge 20a combined with the lower part of the front panel 11a has an overall shape of "U" shape, and includes a coupling part 21 connected to the front panel 11a by screws, which can The rotating shaft 22a rotatably supported by the main body 10 and the hinge body 23 connecting the coupling portion 21 and the rotating shaft 22a in a curved shape.

The hinge body 23 includes a rear extension part 23a extended rearward from the rotating shaft 22a, an inner extension part 23b extended from one end of the rear extension part 23a toward the inside of the main body 10 by bending and extending from the inner extension part 23b. The front extension part 23c extended by bending one end toward the front. At this time, since the length of the front extension part 23c is greater than the length of the rear extension part 23a, the coupling part 21 is located diagonally ahead with respect to the rotating shaft 22a, and a part of the isolation part surrounded by the hinge body 23 is formed between the coupling part 21 and the rotating shaft 22a. Space 27.

As mentioned above, the reason why the hinge body 23 does not connect the coupling portion 21 and the shaft 22a in a straight line, but is bent multiple times to form the isolation space 27 is to prevent the front panel 11a or the lower hinge 20a from rotating when the front panel 11a rotates. Interference occurs with the main body 10, thereby increasing the opening range of the front panel 11a.

Moreover, the outer surface of the hinge body 23 is preferably treated as an arc, so as to prevent interference with the main body 10 when the lower hinge 20a rotates.

The lower hinge 20a is preferably made into one by an injection mold so that it has a certain strength, and the upper part and the lower part are symmetrical to each other centered on the parting line (Parting Line) 24 produced by the joint of the upper and lower molds, and the upper part and the lower part A plurality of ribs 25 intersecting each other are respectively formed so as to minimize deformation caused by shrinkage and deflection that may occur during molding.

As shown in FIG. 3 , a hinge coupling portion 30 is formed at the rear of the front panel 11 a coupled with the lower hinge 20 a.

A plurality of blocks 31 are formed on the hinge joint part 30, and a plurality of fixing grooves 21a are formed on the coupling part 21 of the lower hinge 20a corresponding to the blocks 31, so that the blocks 31 can be fixed by insertion.

In addition, a plurality of sleeves 32 having threaded holes 32 a are formed on the hinge joint portion 30 , and insertion slots 21 b corresponding to the sleeves 32 are provided on the connecting portion 21 of the lower hinge 20 a for inserting the sleeves 32 . And, in order to couple a screw to the sleeve 32 inserted into the insertion groove 21b, a screw hole 22 is formed at one side of the insertion groove 21b.

As described above, when the plurality of blocks 31 formed at the hinge coupling portion 30 are inserted into the plurality of fixing grooves 21a formed at the coupling portion 21 of the lower hinge 20a corresponding to the blocks 31, the lower hinge 20a is temporarily fixed to the hinge. Combining part 30, and the position of the screw hole 22 formed in the coupling part 21 and the threaded hole 32a formed in the sleeve 32 of the hinge joint part 30 are consistent. In this state, if a screw is coupled through the screw hole 22 of the coupling portion 21, the lower hinge 20a is firmly coupled to the hinge coupling portion 30 of the front panel 11a. Also, as the contact area where the block 31 is inserted into the fixing groove 21a increases, it is possible to reduce the cutting force on the screw due to the dead weight of the front panel 11a.

As described above, the structure in which a plurality of blocks 31 are formed on the hinge coupling portion 30 and a corresponding plurality of fixing grooves 21a are formed on the coupling portion 21 of the corresponding lower hinge 20a is nothing more than coupling the lower hinge to the front panel 11a. In addition, the lower hinge can be formed in various ways such as forming a plurality of blocks 31 on the lower hinge 20a, and forming fixing slots 21a for inserting the plurality of blocks 31 on the hinge joint 30. 20a is combined on the front panel 11a.

As shown in FIG. 4, the upper hinge 20b fixed to the upper portion of the front panel 11a is substantially the same as the lower hinge 20a in terms of its structure. Only, the rotating shaft 22a of the lower hinge 20a only protrudes downward, but the rotating shaft 22b of the upper hinge 20b is divided into a lower rotating shaft 22b' protruding downward and an upper rotating shaft 22b" protruding upward. In this way, only an upward hinge is formed on the upper hinge 20b. The reason for the protruding upper shaft 22b" is to guide the upper shaft 22b" according to the hinge cover 42 described below.

FIG. 5 shows a combined body 35 in which the lower hinge 20a and the upper hinge 20b are combined with the front panel 11a. When the hinge 20 is combined with the front panel 11a, preferably the hinge is combined with the rear inner side of the front panel 11a to prevent the hinge 20 from being exposed outside when the front lower part of the main body 10 is closed by the front panel 11a.

In this way, in order to rotatably combine the combination body 35 combined with the hinge 20 on the front panel 11a to the front lower part of the main body 10, the lower and upper sides of the main body 10 form a lower hinge groove 40a and an upper hinge groove 40b respectively for insertion and formation. It is rotatably supported by respective rotation shafts 22a, 22b of the lower hinge 20a and the upper hinge 20b, as shown in FIGS. 6a and 6b. In addition, a hinge receiving space 41 is provided for easy installation of the combined body 35 on the upper side of the upper hinge groove 40 b on the main body 10 .

To mount the front panel 11a incorporating the hinge 20 on the main body 10, the shaft 22a of the lower hinge 20a is inserted into the lower hinge groove 40a, and the shaft 22b' of the upper hinge 20b is inserted into the upper hinge groove 40b. At this time, by making the height of the hinge receiving space 41 higher than the shaft 22b of the upper hinge 20b, the shaft 22b protruding in the vertical direction is prevented from being caught on the main body 10 when the upper hinge 20b is accommodated.

However, due to the hinge receiving space 41, when the combined body 35 combining the hinge 20 and the front panel 11a is lifted upwards, the shafts 22a, 22b are separated from the hinge grooves 40a, 40b, and the combined body 35 may be separated from the main body 10. In order to prevent the front panel 11a rotatably mounted on the main body 10 from being separated from the main body 10, a hinge cover 42 is provided for pressing the upper hinge while supporting the upper shaft 22b″ of the upper hinge 20b by being coupled to the hinge receiving space 41. 20b.

As shown in Figure 7, the hinge cover 42 is provided with a curved surface 42a contacting the inner surface 41a of the hinge accommodation space 41 and a supporting part 42b for supporting the upper shaft 20b" of the upper hinge 20b. And, the bottom of the hinge cover 42 is provided with The protrusion 43 is used to limit the rotation range of the upper hinge 20b when the front panel 11a is rotated to prevent the front panel 11a from opening beyond a predetermined range. The front of the hinge cover 42 is provided with an insertion space 44 for inserting a screw 45. Used to combine the hinge cover 42 on the inner surface 41 a of the hinge receiving space 41 .

FIG. 8 is a front view showing that the hinge cover 42 is combined with the hinge receiving space 41 to prevent the upper hinge 20 b from coming out of the hinge receiving space 41 .

As mentioned above, one side is hinged to the front panel 11a of the main body 10 and the other side is provided with a fixing device 50 for maintaining the closed state of the front panel 11a, as shown in FIG. 1 . The fixing device 50 includes a magnet 50a arranged on the bottom plate 10a of the main body 10 and the upper side of the front panel 11a, and a metal plate 50b arranged on the lower side of the front panel 11a and the upper side of the main body 10 corresponding to the position of the magnet 50a. The structure described above is only an example of the fixing device 50, and the magnet 50a and the metal plate 50b may be exchanged.

The structure of the air conditioner provided according to the preferred embodiment of the present invention has been described above, and the working process of the suction panel 11a of the air conditioner will be described below.

As shown in FIGS. 9 a and 9 b , when the front panel 11 a is rotated counterclockwise around the hinge 20 to open the lower front portion of the main body 10 , the hinge 20 rotates around the rotating shaft 22 .

If the front panel 11a is directly connected to the rotating shaft 22, when the front panel 11a rotates around the rotating shaft 22, one side of the front panel 11a interferes with parts such as the suction grill 12a arranged on the side of the main body 10, causing the parts to phenomenon of being damaged. However, since the front panel 11a is hinged to the main body 10 through the "U"-shaped hinge 20 having the isolation space 27, even if the front panel 11a is rotated in order to open the front panel 11a, the front panel 11a is closed by the "U"-shaped hinge 20. Rotates while being pushed forward, and thus rotates with a predetermined distance from the main body 10 . This eliminates the problem of interference between the front panel 11 a and the main body 10 .

And, since the front panel 11a can be opened more than 90 degrees, the front lower part of the main body 10 can be fully opened, thereby widening the working space for cleaning the filter or repairing the inside of the air conditioner.

In addition, since the front panel 11a is hinged to rotate in the left and right direction to open and close the front lower portion of the main body 10, the front panel 11a can be easily opened and closed.

In summary, according to the air conditioner provided by the present invention, the front panel can be easily opened and closed with relatively small force.

In addition, since the front of the main body can be fully opened to ensure a sufficient work space, it is relatively easy to clean the filter or maintain the inside of the air conditioner.

Also, since the hinges are not exposed outside the main body when the front panel is closed, the appearance of the air conditioner can be improved.
