Electric food smoker
View Patent ↗An electric food smoker includes a heating element that provides a main source of heat and a separate smoke element that is controlled independently from the heating element and provides heat to a wood chip box. Separate control of the heating element and the smoke element allows providing a cold smoke cycle for the food smoker. A hot smoke cycle provides independent control of the heating element and the smoke element according to a hot smoke program. A fast smoke cycle allows adding more smoke during any existing cycle.
1. A food smoker comprising:
a first heating element;
a second heating element; and
a controller that independently controls the first heating element and the second heating element by turning the first heating element on and off independently of the state of the second heating element and by turning the second heating element on and off independently of the state of the first heating element according to a plurality of programs stored in a memory including:
a hot smoke program;
a cold smoke program; and
a fast smoke program that runs simultaneously with a currently-running hot smoke program or a currently-running cold smoke program.
2. The food smoker of claim 1 wherein as long as temperature of a cooking chamber in the food smoker is within a specified difference from a specified cold smoke temperature, the cold smoke program turns on the second heating element and does not turn on the first heating element to maintain the specified cold smoke temperature.
3. A food smoker comprising:
a first heating element;
a second heating element
a controller that independently controls the first heating element and the second heating element by turning the first heating element on and off independently of the state of the second heating element and by turning the second heating element on and off independently of the state of the first heating element according to a plurality of programs stored in a memory;
a water pan that substantially covers the first heating element and that includes a plurality of louvers positioned in proximity of the first heating element so heat generated by the first heating element can rise through the louvers to food being smoked in the food smoker; and
a water fill spout coupled to a water fill door on a side of the smoker, wherein opening the water fill door provides access to pour water into the water fill spout from outside the smoker, wherein the water fill spout directs the water to a reservoir in the water pan.
4. A food smoker comprising:
a cabinet including a left side panel, a back panel, a right side panel, and a door that define a cooking chamber;
a first heating element in the cooking chamber that has a first power rating;
a second heating element that has a second power rating less than a third of the first power rating of the first heating element;
a controller that independently controls the first heating element and the second heating element according to a plurality of programs stored in memory, wherein the plurality of programs includes:
a hot smoke program;
a cold smoke program; and
a fast smoke program that runs simultaneously with a currently-running hot smoke program or a currently-running cold smoke program; wherein the controller comprises:
a display and a plurality of keys that allow a user to specify time and temperature that apply to a selected one of the plurality of programs;
a wireless interface that allows a handheld device to control the controller; an adjustable vent in proximity to a wood chip box that allows a user to adjust the adjustable vent to increase or decrease airflow near the wood chip box;
a water pan that substantially covers the first heating element and includes a plurality of louvers positioned in proximity of the first heating element so heat generated by the first heating element can rise through the louvers to a cooking chamber in the food smoker;
a water fill spout coupled to a water fill door on one of the left side panel and the right side panel of the smoker, wherein opening the water fill door provides access to pour water into the water fill spout from outside the smoker, wherein the water fill spout directs the water to a reservoir in the water pan;
wherein the wood chip box comprises:
a bottom portion that has a recess dimensioned to receive the second heating element;
a plurality of side portions, wherein at least one of the plurality of side portions has a plurality of holes; and
a lid that has a plurality of openings, wherein the lid is pivotally attached to the wood chip box so the wood chip box may be emptied with one hand by turning the wood chip box upside down, which allows the lid to open by force of gravity and allows the contents of the wood chip box to be emptied by force of gravity;
a light source controlled by the controller that shines to a reflector in the door of the food smoker, wherein the reflector directs the light from the light source to a cooking chamber of the food smoker when the door is closed.
