Low Depth Telescoping Downdraft Ventilator
First Claim
1. A downdraft ventilator comprising:
- a housing and an internal member sized to fit within the housing;
wherein the housing and the internal member combine to form a duct, the duct having an intake opening;
wherein the internal member is slidable within the housing so as to be telescoping with respect to the housing;
an actuator operatively connected to the internal member and the housing, wherein the actuator moves the internal member with respect to the housing;
a fan positioned at one end of the duct; and
an electronic control system that controls the actuator and the fan, the electronic control system having a user interface.

Abstract
A low depth telescoping downdraft ventilator controlled by an electronic controller providing a precisely controlled and efficient way of removing gases and fumes is disclosed. The low depth telescoping downdraft ventilator has the ability to fit behind a built-in oven placed below a cook top unit. The telescoping downdraft ventilator has an almost infinitely selectable range of heights above a cook top with a built in oven. The ventilator collects and draws in exhaust fumes and smoke, filters it and re-circulates or expels it either outdoors or indoors. The inner member of the telescoping ventilator may house the exhaust fans and may move up or down without the use of mechanical switches for elevation detection and stopping. The ventilator may have sensors to detect temperatures, filter change need, fan speeds, telescoping stop points, energy consumption, resistance and voltage, enabling programmable set point operation.

14. A downdraft ventilator comprising:
-
a housing having a top end and a bottom end;
an internal member sized to fit within the housing, the internal member having an intake opening;
wherein the housing and the internal member combine to form a duct, and wherein the internal member is telescoping with respect to the housing so as to allow for a portion of the intake opening to extend beyond the top end of the housing;
an actuator operatively connected to the internal member and the housing, the actuator being configured to move the internal member with respect to the housing;
a fan located at the bottom end of the housing; and
an electronic control system that controls the actuator and the fan. - View Dependent Claims (15, 16)

17. A downdraft ventilator comprising:
-
a housing and an internal member sized to fit within the housing, the housing and the internal member combining to form a duct;
wherein the internal member has an upper end with an intake opening, wherein the inner member is slidable within the housing so as to be telescoping with respect to the housing so as to allow for a portion of the intake opening to extend beyond an upper end of the housing, and a plurality of fans positioned at the upper end of the internal member;
an actuator operatively connected to the internal member and the housing, the actuator being configured to move the internal member to a desired position with respect to the housing; and
an electronic control system that controls the actuator and the fan, the electronic control system having a user interface. - View Dependent Claims (18, 19, 20)
