Description

Indoor Unit Exhaust Holl Opening And Closing Apparatus Of Air Conditioner}

The present invention relates to an indoor unit discharge opening and closing device of the air conditioner, and more particularly, the discharge opening provided in the upper part of the indoor unit of the air conditioner to automatically open and close the discharge opening in accordance with the operation of the air conditioner to prevent the inflow of foreign matter to the discharge opening side In addition, the present invention relates to an indoor air outlet opening / closing device of an air conditioner that guides it when discharging cold air so that cold air is discharged more smoothly.

As is well known, the air conditioner (hereinafter referred to as "air conditioner") is a cooling effect by absorbing the surrounding heat when the liquid evaporates, and in addition to the cooling operation is also performed dehumidification.

An air conditioner having such a function is composed of a pressurizer for compressing a refrigerant into a high temperature and high pressure gas form, a condenser for liquefying the high temperature and high pressure refrigerant compressed by the compressor, and a heat exchanger for evaporating the refrigerant expanded by an expansion valve. The cooling air heat-exchanged while passing through the heat exchanger is forcedly blown into the room where cooling is required by a blower (blower).

Among air conditioners, packaged air conditioners, which are mainly installed and used in a small cooling space such as a home or a restaurant, are divided into outdoor units and indoor units. The outdoor unit includes a compressor for compressing a refrigerant and a condenser for condensing the refrigerant. The outdoor unit is installed outside the roof or the veranda of the building due to noise and heat emission during the operation of the outdoor unit, and the indoor unit compresses the refrigerant with the compressor for compressing the refrigerant. The condenser is equipped inside it.

1 is a perspective view showing an indoor unit of the conventional air conditioner described above.

As shown in the indoor unit 10 of the air conditioner, the front panel 12 is coupled to the front surface of the body 11 made of a rectangular parallelepiped, and the middle portion of the front panel 12 can operate an operation operation of the air conditioner. The driving operation unit 13 is provided.

In addition, the discharge port 14 and the suction port 15 are respectively provided in the upper and lower parts of the body 11 of the indoor unit 10 so as to discharge and suck air in the room.

The suction port 15 is provided with a suction grill 16 for supporting a filter (not shown) while providing a beautiful appearance, and the discharge port 14 controls a direction of the air discharged to the room through the suction port 16. A plurality of up and down wind direction control plates 17 and left and right wind direction control plates 18 arranged at intervals are provided.

At this time, the discharge port 14 is provided with an opening and closing device 19 for preventing the inflow of foreign matter, as shown in Figure 2 and 3, this opening and closing device 19 is the body 11 of the indoor unit (10) The plate-shaped support member 20 to be coupled is provided, and guide members 21 having guide grooves 21a are fixed to both ends of the support member 20, respectively.

In addition, the support member 21 is formed with an insertion hole 23 for inserting the shaft 22a of the motor 22 which is driven forward / backward by receiving power according to the control signal of the driving operation unit 13, The pinion gear 24 is rotatably fixed to the shaft 22a of the motor 22 inserted through the insertion hole 23.

In addition, each end is inserted into the guide groove (21a) of the guide member 21 is provided with a plate-shaped blocking plate 25 for opening and closing the discharge port (14).

At this time, in order to enable the blocking plate 25 to be moved up and down, one end is fixed to the blocking plate 25 and one side of the movable member is provided with a rack gear (26a) to be engaged with the pinion gear 24 ( 26).

When the operation of the driving operation unit 13 provided in the front of the indoor unit 10 of the air conditioner is configured in such a state that the discharge port of the indoor unit is blocked, the motor 22 receives power as shown in FIG. 4. The pinion gear 24 is rotated forward by the driving of the motor 22.

Due to the rack gear 26a engaged with the pinion gear 24 by the forward rotation of the pinion gear 24, the movable member 26 is a guide of the guide member 21 in which the blocking plate 25 is fixed to both ends of the support member 20. The discharge port 14 is opened while being guided downward along the groove 21a.

As described above, the indoor unit discharge port of the air conditioner can be opened and closed by the opening and closing device to prevent the inflow of foreign substances.

However, the opening and closing device provided in the indoor unit of the air conditioner is simply composed of a plurality of members, such as a moving member, a supporting member, a guide member, a rack gear pinion gear, and the like, to simply open and close the discharge port. There was a problem to raise.

Accordingly, the present invention has been made in order to solve the above problems, it is configured to automatically open and close the discharge port of the indoor unit with a simpler structure, and at the same time to open and close the door to the rear of the air conditioning body during operation is discharged to the discharge port side The purpose is to provide an indoor unit discharge opening and closing device of the air conditioner to guide the cold air.

The present invention for achieving the above object consists of a panel forming the rear and both sides and a front panel coupled to the front of the panel, the outer panel is formed, the upper and lower portions of the front panel to discharge and suck the air in the room And an indoor air outlet opening / closing device of an air conditioner configured to open and close the discharge port by using an opening / closing door rotated by driving of a motor in an indoor unit of an air conditioner each equipped with a suction port, wherein the opening door is formed of a curved surface of a plate, The first and second connection portions each having an integrally extended coupling hole for coupling the shaft of the motor and an insertion hole for joining the protrusion formed on one side of the indoor unit are provided to the rear panel side of the indoor unit by forward / reverse driving of the motor. Characterized in that it can be rotated.
