US 2009/0013989 A1 · LINEAL SLOT VENTILATOR WITH INTERNAL CLEANING SYSTEM AND ADJUSTABLE BAFFLE

Abstract

In an exemplary embodiment, this system is found within a kitchen hood, such as those found in restaurants, used to remove excess cooking heat and grease. Building fire safety and sanitation codes mandate routine hood maintenance to maintain fire safety, operator comfort and workplace sanitation. Conventional maintenance can be very messy, time consuming and quite expensive. In an exemplary embodiment, the hood is fabricated to incorporate an integral heat exchanger which further creates a trough housing a grease extraction device. The exchanger and trough are located in such a manner that collected heat and/or grease may be removed from the exhaust air stream and further fabricated to permit automatic and/or semi automatic cleaning of both devices and trough. This invention improves fire safety and sanitation, saves time and reduces maintenance costs. Cleaning is achieved using less energy and keeps the heat exchanger at peak efficiency to further enhance energy savings.

Dependent claims

1) A system for cleaning kitchen hood grease removal and/or other devices by submersion and/or soaking without removal from the hood or position in which they are installed for normal operation, said system comprised of:

a. A linear air induction slot located above the grease removal devices.
b. A full length trough that creates a conduit for airflow from the induction slot to the grease removal devices.
c. A tapered bottom of the full length trough that enhances natural drainage of grease and cleaning agents by creating a pitch to a drain device.
d. A full length baffle that diverts exhaust airflow from the induction slot down into the trough and then up into the grease removal device.
e. A drain that communicates between the pitched bottom of the trough and a floor drain
f. A connection to a grease trap through the hood drain for removal of collected grease
g. A valve to close the hood drain
h. A fill trough fill line to set a level required for soak in place cleaning of all components and surfaces
i. The design of the interior components that permits installation beneath the fill line and maintains airflow and grease removal functions.
j. A method of introducing cleaning agents through the induction slot.
k. A method of using gravity and pressure of water head to drain grease deposits from a soaking chamber within a kitchen hood.
