The second component and the third component are removably attached to the first component. The second component includes a first plate portion to which a conduit is connected. The third component includes a second plate portion. Any one of a plurality of side portions of the conduit attachment component is a first side portion, and a side portion of the plurality of side portions, adjacent to the first side portion, is a second side portion. In a first state, the first plate portion is the first side portion, and the second plate portion is the second side portion. In a second state, the first plate portion is the second side portion, and the second plate portion is the first side portion.

Indoor unit of air-conditioning apparatus

An indoor unit of an air-conditioning apparatus includes a wind direction vane, a vane motor, an air passage wall, and a shaft joint member. Between a vane shaft and the air passage wall, an annular gap is provided. The shaft joint member includes a flange portion between the air passage wall and the vane motor. The flange portion radially extends outward from a center, thereby causing air that flows toward the vane motor through the annular gap to be diffused outward relative to a direction toward the vane motor.

An indoor unit of an air-conditioning apparatus includes a heat-medium heat exchanger, an air vent valve, a drain pan, and a hose. The heat-medium heat exchanger is provided in a housing to cause heat exchange to be performed between a heat medium and indoor air. The air vent valve allows air to escape from a heat medium passage that allows the heat medium to flow in the heat-medium heat exchanger. The drain pan is provided below the heat-medium heat exchanger to receive condensation water generated at a surface of the heat-medium heat exchanger. The hose has flexibility, and is attached to the air vent valve, and provided to let out the air along with the heat medium from the heat medium passage to the inner space in the drain pan. The hose has a double-wall structure and an upper end portion of the hose is fixed to the air vent valve.

Indoor unit of air-conditioning apparatus and air-conditioning apparatus

An indoor unit of an air-conditioning apparatus includes: a heat exchanger which generates conditioned air by carrying out heat exchange between refrigerant and indoor air; and a drain pan disposed below a lower end of the heat exchanger to correct dew condensation water. The drain pan includes at a side portion thereof: a side dew receiving portion which receives dew condensation water; and a recessed portion disposed below the side dew receiving portion, the recessed portion being recessed toward an other side portion opposite to the side portion. A side face of the drain pan is provided with a heat insulating sheet covering an entire opening of the recessed portion.

Provided is an indoor unit for an air-conditioning apparatus capable of preventing crazing, which occurs in a fixing claw or a claw receiver due to intrusion of oil or solvent. The indoor unit for an air-conditioning apparatus includes a rear casing and a front casing. An upper wall is formed, and an overlap portion is formed. The fixing claw is provided, and the claw receiver is provided. The upper wall has a front portion on a front side with respect to the fixing claw, and the claw receiver protrudes rearward from the overlap portion. A recessed portion which is opened upward is formed on a front side of the claw receiver of the overlap portion.

Indoor unit for an air-conditioning apparatus

An indoor unit of an air-conditioning apparatus includes: an air purifying filter including a filter body for air purification, a pair of bearing units, and a pair of protrusions that extend outward from the filter body; and an air filter for dust collection including a pair of shaft units coupled with the respective bearing units, and a pair of supports accommodating the respective protrusions. The protrusions are placed into the respective supports from the direction of the respective shaft units.

A communication-adapter mounting device is used for mounting a communication adapter that relays communication between an air-conditioning apparatus and another apparatus. The communication-adapter mounting device includes a body into which the communication adapter is to be accommodated and from which the communication adapter is allowed to be removed, and a clip to mount the body to a housing of the air-conditioning apparatus. A mounting plate of the body includes a mounting hole for securing the communication-adapter mounting device to an installation location in which to install the communication adapter. Further, the body has a clip holding mechanism to hold the clip and to allow the clip to be removed.

Communication-adapter mounting device

A communication device constitutes part of an apparatus and communicates with other apparatuses. The communication device includes a case having an opening; a plurality of indicator lamps accommodated in the case, at a position corresponding to the opening; and an indicator lamp cover that is provided so as to be slidable in a direction in which the plurality of indicator lamps are arranged and that is used to adjust an opening degree of the opening.

Communication device and air-conditioning apparatus

An indoor unit of an air conditioning device which is installed on a wall surface of a room includes an air sending fan which sends room air from an air inlet disposed at an upper part to an air outlet disposed at a lower part of a front side; heat exchangers disposed at the upstream side of the air sending fan; and a back case which is located close to the wall surface with respect to the air sending fan and supports the heat exchangers, wherein the back case is composed of an air outlet passage wall member which forms an air outlet passage for air blown out from the air sending fan and an installation member which is located on a back side of the air outlet passage wall member and is mounted on an installation plate which is fixed on the wall surface with the air outlet passage wall member and the installation member being arranged in parallel in the front and back direction, and a first space is formed between a back surface of an air outlet passage wall of the air outlet passage wall member and the installation member.

Provided is a thermistor fixing structure capable of facilitating insertion of a thermistor into a temperature sensitive cylinder, and preventing the thermistor from easily dropping off the temperature sensitive cylinder. In a thermistor fixing structure (), a fixture () for pressing a thermistor () against an inner surface of a temperature sensitive cylinder () includes an inner bending section () formed at one end portion () of a longitudinal section () so as to function as a stopper for the thermistor () inserted into the temperature sensitive cylinder () from a cylinder insertion end (), an outer bending section () formed at the one end portion () of the longitudinal section () so as to be opposed to a cylinder stop end (), and an inner folding section () and an outer folding section () formed at another end portion () of the longitudinal section () so as to sandwich a cylinder top surface of the temperature sensitive cylinder (). A side surface of the thermistor () is pressed at two points corresponding to an apex of a projecting portion () formed on the inner folding section () and a distal end () of a pressing section () formed continuously with the inner folding section (), and a contact angle (&#x3b1;) formed between the pressing section () and the side surface of the thermistor () on the cylinder insertion end () side is an acute angle.

Thermistor fixing structure, thermistor removing method, and air-conditioning apparatus

An indoor unit of an air-conditioning apparatus includes a housing having a wall extending in a horizontal direction, and a front panel covering at least a part of a front side of the wall. On a region of the wall covered by the front panel, an opening leading to a front end of a space in which a network repeater for wirelessly communicating with a network is to be contained is formed. The opening is configured to be exposed in a state in which a whole or a part of the front panel is removed or opened.
