Safety cabinet with simplified operability
The invention pertains to a safety cabinet with an interior that is enclosed by a housing and a housing front side with a work opening that can be closed with a height-adjustable window. The safety cabinet contains an operating unit for controlling device functions which is integrated into the housing. The operating unit comprises at least one rocker button, the button assignment of which changes depending on the operating state of the safety cabinet in such a way that a certain device function can be controlled in the respective operating state by actuating a button of the rocker button.
1. A safety cabinet comprising:
an interior enclosed by a housing, the interior comprising a housing front side
a work opening disposed on the housing front side;
a height-adjustable front window, that is configured to permit access to the work opening; and
an operating unit integrated into the housing for controlling the safety cabinet functions, wherein the operating unit comprises a rocker button, wherein an operability function of the rocker button dynamically adjusts to control safety cabinet functions in response to a specific operating state, wherein the operability function for the operating state is predetermined.
2. The safety cabinet according to claim 1 , wherein the rocker button, comprises a one-way rocker or a two-way rocker.
3. The safety cabinet according to claim 1 , further comprising a control program that is integrated into a control software of the safety cabinet in order to adjust the button assignment.
4. The safety cabinet according to claim 1 , wherein the button assignment of the rocker button in the operating state safety cabinet switched off is chosen such that an actuation of the rocker button switches on the safety cabinet and changes the safety cabinet over into a different operating state.
5. The safety cabinet according to claim 1 , wherein one of the following processes is activated in response to the activation of the safety cabinet:
switching on the ventilation
switching on the lights
connecting the integrated power outlets to the supply voltage displacing the height-adjustable front window into the working position.
6. The safety cabinet according to claim 1 , wherein, after switching on the safety cabinet, the button assignment is changed such that at least one of the following processes can be carried out in an arbitrary sequence by actuating the rocker button:
switching on the ventilation
switching on the lights
connecting the integrated power outlets to the supply voltage
displacing the height-adjustable front window into the working.
7. The safety cabinet according to claim 1 , wherein the button assignment in the operative state of the safety cabinet is chosen such that the displacement of the height-adjustable front window is controlled by actuating the rocker button.
8. The safety cabinet according to claim 7 , wherein the button assignment in the operative state of the safety cabinet is chosen such that the safety cabinet is switched off if the operator continues to actuate the rocker button after the front window has been displaced into a completely opened or completely closed position.
9. The safety cabinet according to claim 1 , wherein when a defect is detected and/or an alarm is triggered, the button assignment is changed in such a way that the defect message or the alarm is acknowledged when the rocker button is actuated.
10. The safety cabinet according to claim 1 , wherein the rocker button needs to be actuated for a predetermined duration in order to switch the safety cabinet on and/or off.
11. The safety cabinet according to claim 1 , wherein the rocker button is integrated into the front side of the housing and/or into the interior.
12. The safety cabinet according to claim 1 , wherein the safety cabinet contains a display element that displays the current operating state of the safety cabinet and/or the respective button assignment of the rocker.
13. The safety cabinet according to claim 1 , further comprising a remote-control for controlling the device functions.
