Description

Inlet grille opening and closing structure of air conditioner

The present invention relates to an air conditioner such as a window type air conditioner, and more particularly, to an inlet grill opening and closing structure for attaching and detaching an air filter that collects dust contained in the air when indoor air is sucked into the body.

In general, an air conditioner is referred to as an "air conditioner," which is a cooling device that lowers a room temperature to a temperature below a predetermined temperature by inhaling hot air in a room and cooling and discharging it by a heat exchange action by a heat exchanger.

The air conditioner is classified into an upper type, a wall type, a window type and the like according to the installation place and the installation position.

The upper tooth type is installed on the floor of the room, the wall type is attached to the wall of the room, and the window type is attached to the window.

At this time, although the indoor unit and the outdoor unit are separated from each other, the window type is an indoor unit and an outdoor unit.

Referring to Figure 1 attached to the structure of a conventional general air conditioner as follows.

1 is a perspective view showing a general air conditioner, the main body 1 having a plurality of discharge holes (1a) formed on both sides and the upper side so as to be located on the outdoor side when installed in a window (not shown), and the front of the main body A fixed front grill (2), an air filter (3) detachably mounted to the front grill and collecting dust contained in the air when suctioning indoor air into the main body, and air mounted on the front grill An inlet grill 4 having a plurality of suction holes 4a, which are rotatably installed to take out the filter and has a long hole in the horizontal direction, and a horizontal which determines the discharge direction of the cool air discharged and installed on the right side of the front grill. And a vertical thermal bridge (5) and an indoor thermal bridge installed at the rear of the front grill to convert hot air sucked by a driving fan (not shown) into cold air by heat exchange. (Not shown), a scroll for guiding cool air passing through the indoor heat exchanger toward the horizontal and vertical louvers, and an outdoor unit installed on the base to be located at the outdoor side in the main body to exchange heat with external air. And a side heat exchanger (not shown), and a control unit 7 installed on one side of the front grill to set an operation mode.

If the user sets the cooling mode by operating the switch of the control unit 7 to cool the room while the air conditioner is configured as described above, the air conditioner is driven according to the set control signal, thereby cooling the room. .

That is, when the compressor is driven according to the selected control signal to form a refrigeration cycle, the temperature of the indoor heat exchanger drops.

In this state, when the blower fan located at the indoor side is rotated by the driving of the motor and the indoor hot air is sucked into the main body 1 through the suction hole 4a formed in the inlet grill 4, the hot air of the indoor After passing through the indoor heat exchanger, it is cooled by heat exchange with cold refrigerant flowing through the refrigerant pipe, and then scrolled and discharged along the path determined by the vertical and horizontal louvers (5) (6) on the discharge side. do.

Through the operation as described above, the refrigerant introduced through the refrigerant pipe of the indoor heat exchanger and the refrigerant heated by the heat exchange are re-introduced into the compressor through the outdoor heat exchanger through the refrigerant pipe and compressed to high temperature and high pressure. Since it is moved to the indoor heat exchanger to perform the heat exchange action as described above, it becomes possible to continuously cool the room.

The air conditioner is an air filter (3) detachably mounted on the inner surface of the front grill (2) in the air when the air in the room is sucked into the interior of the main body 1 by the suction force according to the driving of the blowing fan. The fine dust contained will be collected.

Accordingly, when a large amount of dust is collected in the air filter 3 detachably mounted on the inner side of the front grill 2 as the air conditioner is operated for a long time, the front grill is reduced because the suction efficiency of the indoor air is reduced. The inlet grille 4 is installed on the front grille 2 so as to be openable and detachable so that the air filter 3 can be removed from (2), cleaned, and then remounted.

2 is an exploded perspective view showing a hinge structure of a conventional inlet grill, Figure 3 is an exploded perspective view showing a conventional locking structure, looking at the opening and closing structure of a conventional inlet grill as follows.

In the conventional air conditioner, as shown in FIG. 2, fastening holes 8 are formed at both upper sides of the front grill 2, and upper and lower sides of the inlet grill 4 are fitted into fastening holes formed at the front grill. The rotating shaft 9 is formed.

And as shown in Figure 3 a pair of locking pieces (10) having elastic force on each of the lower sides of the front grill (2) are provided, respectively, and the locking projection (batch projection for holding the locking piece to hold the locking piece in the lower portion of the inlet grill (4) 11) is formed.

Therefore, when the inlet grille 4 is closed on the front grille 2, the locking protrusion 11 formed on the inlet grille 4 is interposed between the pair of locking pieces 10 to lock the inlet grille during operation of the air conditioner. 4) will remain locked from the front grill 2.

In this state, since the air conditioner is operated for a long time, when the dust is collected in the air filter 3 mounted on the front grill 2 and the air filter is to be cleaned, the air filter 3 is separated from the front grill 2. You must

To this end, if the locking piece 10 is pulled forward while the lower part of the inlet grille 4 is held, the locking projection 10 is opened to both sides while causing elastic deformation by the locking protrusion 11, so that the locking projections caught between the locking pieces are held. Since the inlet grille 4 is opened about the rotation shaft 9, the air filter 3 can be taken out from the front grille 2 as shown in FIG. 4.

However, since the inlet grille 4 opened and closed for cleaning the air filter 3 can only be opened and closed in one direction as shown in FIG. There was a problem that it was troublesome to take out the air filter 3 from the grill 2.

That is, in order to take out and clean the air filter 3 from the front grill 2, the operator can only take out the inlet grill 4 from the front grill 2 so that the air filter 3 can be removed from the front grill 2. do.

This problem has been a serious problem, especially in the case of export goods, because the Gumi region installs the window near the floor.

The present invention has been made to solve such a problem in the prior art, and an object thereof is to make it easy to remove the air filter from the front grill as needed irrespective of the installation position of the air conditioner.

According to an aspect of the present invention for achieving the above object, the inlet grille is hinged to the front grille so as to rotate about an upper portion of the front grille on which the air filter is mounted, and the locking means is provided at the lower portion of the front grille and the inlet grille. In the air conditioner, a front grille and an inlet grille are formed on the front and the bottom of the front symmetry with respect to a horizontal center line, and at least one of the inlet grille is installed on the upper side of the front grille. The locking protrusion is formed on the inlet grille as it is installed to open and close, and the locking piece locks the inlet grille to the front grille, and is formed on both sides of the lower portion of the front grille so as to be pivotally inserted into the rotating shaft or the fastening hole formed on the upper side of the inlet grille. Fastening hole for opening and closing the grille around the lower part of the front grille Is an inlet grill opening and closing structure of the air conditioner is provided, characterized in that consisting of a rotating shaft.
