The present invention relates to a flap fixing structure of a drain fan for an air conditioner, and more particularly, to a flap fastening portion of a drain fan, which includes a snap fit portion to prevent flap shaking caused by discharged air. It is about flap fastening structure.

An air conditioner is a device that controls air temperature, humidity, air flow, and cleanliness to create a comfortable indoor environment.In the indoor unit, it absorbs the heat inside the room to make it low temperature, and in the outdoor unit, the heat absorbed by the heat exchanger of the indoor unit. Emits to the outside. The air conditioner is divided into a wall-mounted air conditioner and a stand-type air conditioner according to an installation method, and is composed of an integrated air conditioner in which an indoor unit and an outdoor unit are provided integrally, and a separate air conditioner that separates the indoor unit and the outdoor unit separately.

1 is a schematic cross-sectional view showing a state in which a flap is fixed to a drain pan constituting a conventional indoor unit for an air conditioner.

As shown, the indoor unit 10 of the air conditioner includes a case 20 for fixing and supporting various components, and a suction unit provided at the front of the case 20 to form a front portion and suction of indoor air. A front frame 30 having a front panel 32 on which a 34 is formed, and a blower 50 disposed in a transverse direction in front of the case 20 to suck low-temperature indoor air passing through the heat exchanger 40. And a heat exchanger 40 positioned at the front and upper sides of the blower 50 to lower the temperature of the intake air by contacting the purified air through an air filter (not shown), and by the blower 50. An orifice 60 for guiding the air flow in a low temperature state, the discharge unit 70 through which air guided by the orifice 60 is discharged, and the discharge unit 70 are provided on the indoor unit of the air conditioner. Flap 80 for controlling the discharge direction during the discharge of air cooled by heat exchange in Consists of the ventilation (40) the lower side drain pan 90 is for collecting water in the air that is generated condenses on the outer walls of the room air and the heat exchanger when the heat exchanger 40 is provided in the.

However, according to the conventional drain fan structure for an air conditioner, when the air guided by the orifice is discharged through the discharge part constituting the base, the flap for adjusting the discharge direction of the air cooled by the discharge air due to the simple mounting state. There was a problem that this shaking phenomenon occurs.

In addition, since the assembly of the flap and the drain pan is a structure in which one of the left and right sides is selected and inserted, it is very inconvenient to assemble.

In addition, when the gap between the flap and the drain pan is too large, noise due to the flap tremors occurs, and when the gap between the flap and the drain pan is too small, there are serious problems such as malfunction of the flap when the rotation of the flap occurs. .

The present invention has been made to solve the above problems, has the following object.

First, a snap fit portion is provided at the flap fastening portion of the drain pan to prevent flap shaking due to discharged air.

Second, the assembly is improved by pressing the flap on the open flap fastening portion of the drain pan constituting the indoor unit of the air conditioner from the top, and after being fastened, the drain pan and the flap are mutually restored as the snap fit portion is restored to its original state. It is to prevent the departure and to prevent the occurrence of noise and failure.

According to the flap fixing structure of the drain fan for the air conditioner of the present invention devised to solve the above technical problem, the drain pan is provided on the lower side of the heat exchanger to collect the condensed water generated during heat exchange with the indoor air, the drain An air conditioner having a flap connected to a fan and adjusting a discharge direction of cold air, the air conditioner comprising: a flap fastening part of which a part provided at a predetermined position of a drain pan to which the flap is fixed is opened; And a snap fit portion provided around the flap fastening portion; Characterized in that it comprises a.

And, the snap-fit portion is preferably provided to have an elastic inward.

In addition, the snap-fit portion is formed at regular intervals in a slot shape around the flap fastening portion.

In addition, the protrusion of the flap is assembled by fitting to the flap fastening portion.

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

2 is a perspective view showing a state in which a flap is fixed to a drain pan of an indoor unit for an air conditioner according to the present invention, FIG. 3 is an enlarged perspective view showing an enlarged portion "A" of FIG. The front view which shows the state in which the flap was fixed to the drain pan of the indoor unit for air conditioners which concerns on this invention, FIG. 5 is sectional drawing "AA" of FIG. 4, FIG. 6 is the indoor unit for air conditioners which concerns on this invention. It is a schematic sectional drawing which shows the state in which the flap was fixed to the drain pan which comprises.

As shown, a drain pan 170 provided below the heat exchanger 130 to collect condensed water generated during heat exchange with indoor air, and connected to the drain pan 170 to adjust the discharge direction of cold air. An air conditioner provided with a flap (180), comprising: a flap fastening portion (176) having a portion open at a predetermined position of a drain pan (170) to which the flap (180) is fixed; And a snap fit portion 178 provided around the flap fastening portion 176; Characterized in that it comprises a.

First, the case 110 constituting the indoor unit 100 of the air conditioner is provided with various components such as a heat exchanger 130 and a blower 150 are fixed and supported therein.

In addition, the front frame 120 having a front panel 122 having a suction unit 124 which is coupled to the front surface of the case 110 and forms an exterior of the front surface and sucks indoor air is mounted.

In addition, impurities such as dust contained in the air sucked by the air filter (not shown) of the mesh disposed between the front panel 122 and the heat exchanger 130 are filtered to impurity on the surface of the heat exchanger 130. Do not stick to this.

In addition, a discharge unit 140 for discharging cold air is provided below the front frame 120.

In addition, a blower 150 provided in the front side of the case 110, that is, the rear side of the front frame 120 to suck hot air from the room to the heat exchanger 130 through the suction part is disposed in the horizontal direction. The blower 150 may be provided by varying the number according to the size or use of the indoor unit (100).

The orifice 160 is formed at the rear side of the blower 150 and guides the direction of the air sucked by the rotation of the blower 150.

In addition, the heat exchanger 130 is provided on the front upper side of the blower 150 to directly lower the temperature of the intake air by performing heat exchange by directly contacting the air sucked through the blower 150.

The heat exchanger 130 is disposed to have a predetermined inclination angle to increase the contact area with air, and the indoor air sucked in contact with the heat exchanger 130 due to the low pressure and temperature characteristics of the refrigerant flowing therein. As it loses heat, the temperature of the indoor air becomes a low temperature state.
