An air conditioner indoor unit is provided. The indoor unit has a housing, a volute and a first heat exchanger. The housing is provided with an installation cavity. The volute is installed in the installation cavity. An air outlet of the volute is inclined towards a bottom of the installation cavity. The first heat exchanger is installed in the installation cavity corresponding to the air outlet. The first heat exchanger extends from a bottom of the volute to a top of the volute. An air inlet cavity is defined by the volute, the first heat exchanger and the bottom of the installation cavity.

A dehumidifier appliance may include a cabinet, a refrigeration assembly, an air handler, and a condensate collection tray. A controller is configured to initiate a dehumidification cycle, determine that the dehumidification cycle has failed, prompt a user to confirm that all external sources of humidity are blocked, receive user confirmation that all external sources of humidity are blocked, determine that the dehumidification cycle is still failing after receiving the user confirmation, and identify a fault with the dehumidifier appliance.

The present invention provides an air purifier. The air purifier is economical and reliable. The air purifier uses water to purify air. The air purifier provides a provision for killing bacteria, algae and prevents mosquitoes from breeding in the water of the air purifier. The purifier includes a housing, an air inlet, an air outlet, an air flow channel, an air driving means and an air exhaust means, a fluid reservoir, a heating module, at least one nozzle, a tray and a fluid drive means. More particularly, in the present invention an atmospheric air is sucked into the air flow channel by the air driving means, wherein the air stream passes under a fluid spray, whereupon a dust particles, pollutants and particulate matters are absorbed by the fluid coming in contact with it and the filtered air exits through the air outlet.
