AI Technical Summary

Benefits of technology

The patent text describes a tray for holding an HVAC controller that can be installed in an indoor unit. The tray has tabs that secure the controller to the indoor unit, a bracket for holding a screw, a drip wall to prevent water from entering, and a cover that protects the controller from impact. The tray can help prevent damage to the HVAC controller during installation and also provides a convenient way to secure it in place.

Problems solved by technology

When providing cooling duty to the air that is circulated through the enclosed space, conditions can exist within the indoor unit that result in the formation of condensate on or around components within the indoor unit.
The formation of condensate within the indoor unit can lead to a failure of the HVAC system due to electrical shorts.
For example, if condensate contacts the PCB of the HVAC controller, the HVAC controller may suffer damage from electrical shorts.

Embodiment Construction

[0013]Embodiment(s) of the invention will now be described more fully with reference to the accompanying Drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiment(s) set forth herein. The invention should only be considered limited by the claims as they now exist and the equivalents thereof.

[0014]FIG. 1 illustrates an HVAC system 100. HVAC system 100 is configured to condition air via, for example, heating, cooling, humidifying, or dehumidifying air within an enclosed space 101. In a typical embodiment, enclosed space 101 is, for example, a house, an office building, a warehouse, and the like. Thus, HVAC system 100 can be a residential system or a commercial system such as, for example, a rooftop system. HVAC system 100 includes various components; however, in other embodiments, HVAC system 100 may include additional components that are not illustrated but typically included within HVAC systems.

Abstract

A tray for an HVAC controller includes a tray base, a first mounting tab secured to the tray base and configured to interlock with a corresponding mount of a cabinet of an indoor unit of an HVAC system, a mounting bracket secured to the tray base and comprising an aperture for receiving a mounting screw therethrough, a drip wall that extends up from the tray base, and a cover extending up from the tray base that includes a wall and a top plate. The cover is positioned to protect a component of the HVAC controller from impact when the HVAC controller is installed in the tray.

Description

TECHNICAL FIELD[0001]The present invention relates generally to a heating, ventilation, and air conditioning (HVAC) system and more particularly, but not by way of limitation, to a tray for protecting an HVAC controller from condensate.BACKGROUND[0002]This section provides background information to facilitate a better understanding of the various aspects of the disclosure. It should be understood that the statements in this section of this document are to be read in this light, and not as admissions of prior art.[0003]HVAC systems typically include an indoor unit that provides heating and cooling duty to air that is circulated through an enclosed space. The indoor unit may include components such as a blower, an evaporator coil, a circuit breaker, and an HVAC controller. The HVAC controller controls the operation of the HVAC system and typically includes, for example, a printed circuit board (PCB) that comprises various components (e.g., capacitors, resisters, circuit traces, and th...
