Problems solved by technology

However, in some cases, the function of the appliance's primary water heater is limited to producing hot water at a temperature high enough to effectively clean and sanitize dishes
For example, rinsing at a lower temperature than expected (eg, 140°F) may not be sufficient to kill microbes and / or melted grease and waxy grime

Embodiment Construction

[0016] Some booster water heaters increase water temperature by converting electrical energy into heat, which is then added to the water by the booster heater. However, the booster water heater does not fully begin to operate until after the initial lag time that can occur with activation. The "response time" of a booster water heater after it is activated refers to the period of this initial lag that is necessary for the booster water heater's heating element to warm up to operating temperature. A container with enough hot water can temporarily supplement the dishwasher's hot water needs during response time. The booster water heater shall be capable of producing a continuous stream of hot sanitizing rinse water as the response time elapses.

[0017] Embodiments provided by the present invention can reduce the response time of a booster water heater. In one embodiment, an immersion heating element can reach operating temperature in seconds; without the technology, the respo...

Abstract

An exemplary embodiment includes a booster water heater for fluids, e.g., water, that has a reservoir for the fluids, at least one electrical heating element extending into the reservoir and a control system for applying an overload voltage to the heating element. In a more preferred embodiment, the booster water heater is used to preheat water in commercial dishwashing applications.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from US Application No. 12 / 346,533, filed December 30, 2008, which is incorporated herein by reference in its entirety. Background technique [0003] The subject of the present application relates to the field of booster water heaters. Booster water heaters can be used, for example, to raise the temperature of water supplied to dishwashers. In particular, the subject matter of this application relates to the operating response time of pressurized water heaters having electric immersion heating elements. [0004] Dirty utensils may contain undesirable microorganisms (such as bacteria, mold, protozoa, etc.) and dirt (such as wax, dried and baked foods, lipstick marks, thin crust, stains, etc.). Systems are therefore designed for use in the commercial food service industry to clean and sanitize soiled tableware such as plates, bowls, saucers, cutlery, glasses, cups, and the like. In some ...
