According to the air conditioner, the front heating cavity in the air inlet assembly is arranged to heat air just entering the air conditioner for the first time, so that when the air is condensed and dried by a refrigerant in the condensation cavity, moisture in the air is more easily condensed into water drops, and finally the air is heated through the rear heating cavity; therefore, air entering the air pump is in a warm and dry state, and the phenomenon that a water film is formed on the surface of the evaporator in winter, and consequently the heat exchange effect of air and the evaporator is affected is avoided.

Heat exchange turbulence structure for avoiding fan and gas water heater

A heat exchange spoiler structure and a gas water heater for avoiding a fan belong to the technical field of household appliances. In the spoiler structure, the spoiler is arranged between the fan and the heat exchanger, and the spoiler includes a plurality of through smoke holes and a heat exchange flow channel arranged in the shell of the spoiler. The heat exchange flow channel is respectively provided with a water inlet and a water outlet, and the heat exchange flow channel is connected with the water flow channel of the heat exchanger. The spoiler also has a step portion that sinks toward the heat exchanger; a smoke collection channel is arranged between the air intake of the fan and the smoke outlet of the heat exchanger, and the smoke collection channel includes a first flow area located below the fan and a second flow area located in other parts, and the first flow area has a resistance reduction opening that the spoiler cannot cover. The heat exchange spoiler structure can make the heat exchange more sufficient on the basis of drainage balance, thereby improving the utilization rate of heat.
