FIG. 5 is a front view showing a fixing plate of the indoor unit for an air conditioner according to the present invention, and FIG. 6 is an 'A-A' line according to FIG. 5. 7 is a rear view showing a fixing plate of an indoor unit for an air conditioner according to the present invention, FIG. 8 is a sectional view taken along the line 'B-B' according to FIG. 7, and FIG. 9 is according to the present invention. It is a use state diagram which shows the state in which the fixed plate of the indoor unit for air conditioners was mounted on the upper side of a drain pan.

As shown, according to the motor support structure of the indoor unit for the air conditioner according to the present invention, a plurality of blowers 110 accommodated in the fan housing 100; A plurality of motors 120 provided on one side of the plurality of blowers 110 with a partition wall therebetween; A fixing plate 130 of an indoor unit for an air conditioner, to which the plurality of motors 120 are sandwiched from above; And a drain pan 140 provided below the fan housing 100. Characterized in that it comprises a.

First, a case of an indoor unit for an air conditioner is fixed and supported therein with various components such as a heat exchanger and a plurality of blowers 110.

Then, the front panel having the front suction grille and the upper suction grille coupled to the front and upper sides of the case to form a plurality of suction holes to form the front and upper side appearances is coupled. This front panel is fastened so that it can be fixed to the front frame.

In addition, impurities such as dust contained in the air sucked by the air filter of the mesh disposed between the front suction grill and the heat exchanger are filtered to prevent impurities from adhering to the surface of the heat exchanger.

In addition, a discharge part for discharging the cooled air is formed on the front frame and the lower side.

And, the inner side of the case, that is, the rear side of the front frame is provided with a blower 110 for sucking the hot air in the room to the heat exchanger side through the front suction grill and the upper suction grill is disposed in the transverse direction, the blower ( 110 is provided by varying the number depending on the size of the indoor unit or the method of use.

Thus, when a plurality of blowers 110 are provided inside the indoor unit for the air conditioner (for example, in a pair), the blowers 110 correspond to the number of blowers 110 provided to drive the blowers 110. A plurality of motors 120 which are driving means are provided.

In addition, the plurality of motors 120 are fixed and supported by a fixing plate 130 that is fitted from the upper side.

The fixing plate 130 for fixing and supporting the plurality of motors 120 includes a plurality of accommodation portions 132 into which the plurality of motors 120 are fitted; An accommodating part 134 recessed inwardly provided above the plurality of accommodating parts 132 to accommodate the plurality of blowers 110; A support part 136 provided between the plurality of accommodating parts 132 so that the fixed plate 130 supports the plurality of motors 120 from the drain pan 140; It consists of.

Among these, the plurality of receiving portions 132 may be partially opened to be formed in the same shape as the appearance of the plurality of motors 120. That is, the plurality of accommodating parts 132 may be formed to have an inner diameter that is substantially the same as or slightly larger than the outer diameter of the plurality of motors 120 so that the plurality of motors 120 may be assembled to each other, thereby fixing and supporting the plurality of motors 120. It is fastened so that it can be prevented from being separated by external shock or shaking.

In addition, a plurality of cutout vibration absorbing portions 132a for cooling the plurality of motors 120 are formed in the plurality of receiving portions 132. Accordingly, the vibration of the motor 120 is eliminated by the plurality of vibration absorbing parts 132a when the air conditioner is driven, thereby absorbing vibrations of the motors 120. The plurality of vibration absorbing units 132a may also serve to cool the plurality of motors 120.

The accommodating part 134 provided on the plurality of accommodating parts 132 is recessed inward to accommodate one end of the plurality of blowers 110.

In addition, the support plate 136 provided between the plurality of receiving portions 132 maintains a proper distance from the drain pan 140, so that the fixing plate 130 can fix and support the plurality of motors 120. .

In addition, a pipe-shaped discharge part 136a for discharging the condensate at a predetermined position of the support part 136 is provided. The discharge part 136a collects condensed water (that is, moisture in the air) generated when the indoor air sucked into the indoor unit of the air conditioner is exchanged by the heat exchanger, and is provided below the fan housing 100. It is discharged to the drain pan 140 side.

An orifice (not shown) is formed on the rear side of the plurality of blowers 110 and guides the direction of the air sucked by the rotation of the blowers 110. After the orifice is sucked by the blower 110, the orifice guides the flow of air cooled at low temperature through heat exchange in the indoor unit to be discharged by the discharge unit.

In addition, the heat exchanger is provided on the front upper side of the plurality of blowers 110, and is in direct contact with the air sucked through the blower 140 to heat exchange to lower the temperature of the sucked air.

The heat exchanger is arranged to have a predetermined inclination angle to increase the contact area with air. Due to the low pressure and temperature characteristics of the refrigerant flowing inside, the heat exchanger loses heat as it comes into contact with the heat exchanger. The temperature of becomes low temperature.

In addition, the drain pan 140 provided below the fan housing 100 prevents condensate from leaking or scattering to the outside.

As described above, the indoor unit for the air conditioner according to the present invention can improve the work efficiency by allowing the plurality of motors 120 driving the plurality of blowers 110 to be assembled at a time through one fixing plate 130. In addition, manufacturing costs can be reduced by dramatically reducing the number of installation parts.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

According to the motor support structure of the indoor unit for an air conditioner according to the present invention as described above, it is possible to assemble a plurality of motors for driving a plurality of blowers at once to create an effect that can improve the work efficiency.

Another effect of the present invention, by assembling a plurality of motors for driving a plurality of blowers through one fixing plate, it is possible to significantly reduce the number of installation parts to reduce the manufacturing cost.
