JPH11316032A - Grill hinge device of window type air conditioner - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate the connection level difference between a front panel and a suction grill member as seen from a front face of an air conditioner by mounting guide shafts and support shafts in a vertically spaced apart manner with a given distance at both sides of an upper end of a front surface of the front panel and mounting guide levers which can change an angle at the support shafts. SOLUTION: From both sides of an upper end of a front surface of an suction opening of a front panel 200, guide shafts 205 are protruded. Support shafts 206 are protruded from both sides below the guide shafts 205 with a given distance. Furthermore, from both sides of an upper end of a suction grill member 210, guide levers 212 which have the center thereof formed in a convex shape in a downward direction are integrally protruded. Rail grooves 213 having rear ends thereof opened are formed in these guide levers 212 such that they are slidably fitted along the outsides of the guide shafts 205 in a rotating manner. In the grill hinge device of a window type air conditioner having the above- mentioned constitution, since the connection level difference between the front panel 200 and the suction grill member 210 is disposed on the upper surface, such a difference cannot be seen from the front surface.

2. Description of the Related Art In a conventional window type air conditioner, as shown in FIG. 1, an evaporator 20 is provided in front of an upper surface of a base panel 10 so as to exchange heat of drawn indoor air with cold air. At the upper end of one side (right side) of the evaporator 20, a blade frame 30 for dividing a discharge area so as to discharge cold and heat-exchanged indoor air passing through the evaporator 20 to the front of the device is installed. On the lower side of the blade frame 30, a control casing 40 is provided so as to accommodate electrical components for controlling the operation of the device.

At this time, the evaporator 20 and the blade frame 30 are simultaneously connected by an indoor casing 50 seated on their upper surfaces, and the control casing 40 is connected to the side of the evaporator 20 and the blade frame 30.
A plurality of vertical blades 6 are screwed to the lower surface of the blade frame 30 so as to adjust the flow of room air discharged through the area of the blade frame 30 in the left-right direction.
0 is set.

Further, an upper portion of the base panel 10 covers the remaining portion except the front of the device to form an external appearance, and has a plurality of ventilation holes 71 on both sides so that air is circulated inside and outside the device. A front panel 80 is connected to the front of the out panel 70 so as to cover the front of the device and form an external appearance, and to suck and discharge indoor air.

Further, a compressor 100 is installed at one side of the center of the upper surface of the base panel 10 so as to compress the circulated refrigerant to a high temperature and a high pressure and supply a cold refrigerant into the evaporator 20. An outdoor casing 110 that supports a condenser (not shown) is provided behind the upper surface of the base panel 10 and is located between the outdoor casing 110 and the indoor casing 50. At the center of the upper surface, a plurality of interval holding brackets 120 are connected at predetermined intervals on the left and right sides so as to support the mutual interval at a predetermined interval.

At this time, a suction port 81 is formed in the front panel 80 at a position corresponding to the area of the evaporator 20 so that room air is sucked. A discharge port 82 is formed at a position corresponding to the area of 30 so that heat-exchanged indoor air is discharged.

In other words, an intake grill member 130 is detachably connected to the area of the intake port 81 so that an air filter (not shown) installed on the front face thereof can be disassembled and cleaned with upper ends on both sides as hinge points.

A plurality of hinge shafts 83 are integrally provided in the horizontal direction so as to be higher than the height of the upper end of the suction grille member 130 on both inner sides of the upper end of the front surface of the inlet 81 of the front panel 80, respectively. A plurality of hinges are fitted to the peripheral surface of the plurality of hinge shafts 83 at both upper and lower ends of the rear surface of the suction grill member 130 so that the suction grill member 130 can be freely attached and detached and rotated vertically. A lever 131 is integrally provided.

At this time, the plurality of hinge levers 131
Is extended in the horizontal direction from the rear surface of the suction grill member 130, and is again bent vertically so that the height of the upper end thereof is higher than the height of the upper end of the suction grill member 130, The hinge shaft 8 at the upper end
A coupling groove 132 having an opening on one side is formed so as to be elastically fitted through the peripheral surface of the third.

When the air conditioner thus constructed is operated, a blower fan (not shown) installed on the rear side of the evaporator 20 is rotated and the air blown by the blower fan causes the suction formed on one side of the front panel 80. The indoor air is sucked through the grill member 130 and the suction grill member 13
Various foreign substances and the like floating in the air while passing through an air filter (not shown) provided on the rear side of the filter 0 are filtered.

Further, the filtered air is sent to the evaporator 20 through the suction port 81 of the front panel 80, passes through the evaporator 20, contacts the surface thereof, and exchanges heat with cold air, and exchanges heat. The discharged air is guided by the indoor casing 50 installed on the rear side of the evaporator 20 and discharged to the blade frame 30, and is discharged to the front of the device through a discharge port 82 formed on the other side of the front panel 80. As a result, the room temperature is cooled to a low temperature.

At this time, the plurality of vertical blades 60 connected to the blade frame 30 are adjusted in the left and right direction by a predetermined angle, or the plurality of horizontal blades 90 connected to the discharge port 82 of the front panel 80 are moved in the vertical direction. When adjusting by a predetermined angle, the blade frame 30 and the discharge port 8
2 flows through a plurality of vertical blades 6.
0 and the changed adjustment angle of the horizontal blade 90 to be sent to a desired place in the room.

[0013]

According to the conventional grill hinge device for a window type air conditioner, the suction grill member 130 can be easily opened and closed in the vertical direction without interference from the front panel 80. In order to be opened and closed, a plurality of hinge shafts 83 projecting from both inner side surfaces at the upper end of the front panel 80 so as to face each other.
The hinge center point at which the plurality of hinge levers 131 protruding from the upper ends of the rear surface of the suction grill member 130 are connected to each other should be installed at a position higher than the height of the upper end of the suction grill member 130. Therefore, as shown in FIG. 2, when the intake grill member 130 is connected to the front panel 80 and the front surface of the air conditioner is viewed from the front, the step surfaces P that are connected to each other become visible. Alternatively, there is a problem that the width of the upper and lower areas of the plurality of suction holes 133 formed on the front surface of the suction grill member 130 is narrowed in accordance with the hinge connection structure, thereby lowering suction efficiency.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned various problems, and an object of the present invention is to provide a structure in which a connecting step surface between a front panel and a suction grill member is visible when viewed from the front of an air conditioner. In addition to improving the external appearance of the appliance, the window hinge of the window type air conditioner is designed to increase the width of the upper and lower areas of a plurality of suction holes formed on the front surface of the suction grille member, thereby increasing the suction efficiency. To provide.
