• the present invention relates to an indoor unit for an air conditioner and a method for assembling an indoor unit for an air conditioner. (Background technology)
• Some air conditioner indoor units are equipped with a heat exchanger and a blower fan, and perform indoor air conditioning by sending the heat-exchanged air into the room.
• a pipe through which the refrigerant flows is connected to the heat exchanger, and heat exchange is performed between the refrigerant flowing from the pipe to the heat exchanger and room air.
• the heat exchanger and the blower fan are often arranged on the support unit so that the heat exchanger covers the upper part of the blower fan.
• the indoor unit of the air conditioner has a support unit that supports the blower fan.
• the support unit bottom frame assembly
• the support unit bottom frame assembly
• the support unit bottom frame assembly
• the indoor unit of the air conditioner according to claim 1 includes a blower fan, a heat exchanger, and a support unit.
• the heat exchanger has a substantially inverted V-shaped cross-section, is connected to a pipe through which a refrigerant flows, and is arranged so as to cover the upper part of the blower fan.
• Support unit Supports the blower fan. Each part of the support unit is located at a level equal to or lower than the height of the top of the blower fan.
• each part of the support unit is located at a position equal to or lower than the height of the top of the blower fan.
• the heat exchanger is arranged so as to cover the upper part of the blower fan. For this reason, when mounting the heat exchanger, each part of the support unit is less likely to obstruct the pipes connected to the heat exchanger. As a result, in the indoor unit of the air conditioner, the installation of the heat exchanger can be facilitated.
• the heat exchanger is attached to the support unit with the blower fan attached, so before the heat exchanger was attached, the blower fan was attached to the support unit. It is in a state.
• each part of the support unit is lower than the height of the top of the blower fan. Therefore, the unit in which the blower fan and the support unit are combined is downsized, and the unit can be easily transported. For this reason, in this air conditioner indoor unit, the unit carrying the blower fan and the support unit is transported. The feedability can be improved.
• the blower fan, the driving device, and the high-power components are arranged in the axial direction. That is, the blower fan, the driving device, and the high-power components are arranged side by side in the horizontal direction. For this reason, the electrical component box is prevented from becoming large in the vertical direction. Thereby, in the indoor unit of the air conditioner, it is possible to easily realize a configuration in which the electrical box is equal to or less than the height of the top of the blower fan.
• the indoor unit of the air conditioner according to claim 6 is the indoor unit of the air conditioner according to claim 4, further comprising a driving device that rotationally drives the blower fan.
• each part of the support unit is located at a position equal to or lower than the height of the top of the blower fan, each part of the support unit is attached to the heat exchanger when the heat exchanger is mounted. There is little risk of obstructing the connected piping. Further, since the rear member is attached after the heat exchanger is attached first, there is little possibility that the rear member obstructs a pipe connected to the heat exchanger. For this reason, in the method of assembling the indoor unit of the air conditioner, the installation of the heat exchanger can be facilitated. (Brief description of drawings)
