Benefits of technology

This patent describes a water heater appliance that includes a fan. The fan can rotate in a first direction and direct air in a direction that is substantially tangential to the first direction. This design can improve the efficiency of the water heater appliance and help to distribute the air evenly throughout the tank. The technical effect of this design is better heating performance and improved user experience.

Problems solved by technology

This diminishes the amount of usable space within a room or area in which a heat pump water heater is located, which is undesirable.
In addition, the spacing between a heat pump water heater and a wall makes it difficult to secure the heat pump water heater to the wall, which certain localities require to prevent inadvertent movement of the heat pump water heater during an earthquake.

Abstract

A water heater appliance defining a vertical direction includes a tank for holding water. The water heater appliance further includes a shroud and a fan. The shroud may be positioned at a top portion of the tank. In addition, the shroud may define a chamber positioned over the tank along the vertical direction, and the shroud may further define a vent assembly extending through the shroud from the chamber of the shroud. The fan may be positioned within the chamber. In addition, the fan may include a hub and a plurality of blades extending from the hub. The plurality of fan blades may be rotatable in a first direction. Further, each of the plurality of blades may be positioned and oriented on the hub such that the fan discharges air in a direction that is substantially tangential to the first direction.

Description

FIELD OF THE INVENTION[0001]The present subject matter relates generally to heat pump water heater appliances.BACKGROUND OF THE INVENTION[0002]Heat pump water heaters are gaining broader acceptance as a more economic and ecologically-friendly alternative to electric water heaters. These systems utilize a condenser configured in a heat exchange relationship with a water storage tank, for example wrapped around the tank in a series of coils. During operation of the vapor compression heat pump cycle, air flows across an evaporator and transfers energy to a refrigerant flowing through the evaporator. As such, the refrigerant exits the evaporator as a superheated vapor and / or high quality vapor mixture. Upon exiting the evaporator, the refrigerant enters a compressor where the pressure and temperature increase and the refrigerant becomes a superheated vapor. The superheated vapor from the compressor then enters the condenser, wherein the superheated vapor transfers energy to the water wi...
