Abstract: A cylindrical heating unit of an exhaust gas processing device is installed in a reactor. The cylindrical heating unit is provided with an exhaust gas introduction port provided in an insertion base part and a heated exhaust gas outlet provided at insertion end. The cylindrical heating unit includes a hollow cylinder, insulators, electric heaters, and holding members. The hollow cylinder has a double structure with an inner cylinder and an outer cylinder made of metal. A plurality of the insulators surround the inner cylinder and are provided at intervals from each other in a heater installation space between the inner cylinder and the outer cylinder. Electric heaters are mounted to the insulators. The holding members are attached to one of the inner cylinder and the outer cylinder or both and hold the insulators in the heater installation space.

Abstract: An air conditioner is disposed with a casing, a filter, an indoor heat exchanger, a blower, and a blowout passage. The casing includes a suction opening and a blowout opening. The filter is disposed downstream of the suction opening and transmits air. The indoor heat exchanger is disposed facing the filter downstream of the filter and performs heat exchange with air that passes through the indoor heat exchanger. The blower is disposed downstream of the indoor heat exchanger and generates a flow of air that is sucked in from the suction opening and is blown out from the blowout opening. The blowout passage includes an air introduction opening disposed facing and downstream of the indoor heat exchanger and guides air from the air introduction opening to the blowout opening. Additionally, the filter has an outer shape that is slanted with respect to the indoor heat exchanger.

Abstract: An indoor unit of an air conditioner includes an indoor heat exchanger, a body, a centrifugal fan, and a shutter. A plurality of discharge passages for discharging air that has passed through the indoor heat exchanger is formed in the body. The centrifugal fan generates a flow of air that passes through the indoor heat exchanger and is blown out of the discharge passages. The shutter is provided to at least one discharge passage of the plurality of discharge passages. The shutter is kept in a closed state by the pressure of the air flow.

Abstract: The indoor unit comprises a body and a cover member. The body has a rear ledge. The rear ledge can be embedded in a wall. The cover member has a plurality of cover elements. The plurality of cover elements is aligned along the direction in which the rear ledge is embedded in a wall. The plurality of cover elements can be partitioned. The cover member covers at least part of the rear ledge.
