Abstract
The utility model discloses a ventilation cabinet control system comprising a door sensor, a controller, an air blower contact switch and an air blower which are connected in sequence. The controller comprises a control unit, a timing unit and an input unit. The time unit and the input unit are respectively connected with the control unit. The door sensor is arranged at a door frame. When a door is opened, signals are sent to the control unit, and the control unit receives the signals transmitted through the door sensor and controls the air blower contact switch to put through so that the air blower can start to run. The ventilation cabinet control system can start the air blower when the door is opened, pumps residual waste from a ventilation cabinet, ensures health of experimenters, can set operation time of the air blower, and is energy-saving and environment-protecting.
Description
Technical field
The utility model relates to the testing equipment field, particularly relates to a kind of vent cabinet and controls system.
Background technology
In occasions such as laboratories, need to guarantee the parameter stabilities such as temperature, air pressure, wind speed of indoor or test operation platform, and can in time get rid of test waste gas and used heat, need ventilating system for this reason.Usually ventilating system comprises blower fan and ventilation shaft, and said ventilation shaft has several suction opeings, and said suction opeing is above operating platform.The test that strictness is for ask for something, its operating platform is arranged in vent cabinet.Vent cabinet is one of indispensable device of ventilating system; Said vent cabinet is a kind of cabinet with the relative closure in certain cavity volume space; Be provided with movably cabinet door in cabinet the place ahead; Be provided with operating platform in the cabinet, utilize this platform to be engaged in various physico-chemical tests behind the door thereby can let the experimenter open cabinet.
Traditional main employing manually of vent cabinet control controlled, and needs personnel to look after, and be very inconvenient.
The utility model content
The technical problem that the utility model mainly solves provides a kind of vent cabinet and controls system, can realize automatic control.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: provide a kind of vent cabinet to control system; Comprise the door sensor, controller, blower fan contact-making switch and the blower fan that connect successively; Said controller comprises control module and the timing unit and the input block that are connected with said control module respectively;
Said door sensor is installed in the doorframe place, when door is opened, sends signal and gives control module;
Said control module is received the signal that door sensor transmits, and control blower fan contact-making switch is connected the blower fan entry into service.
In preferred embodiment of the utility model, said door sensor is the tongue tube sensor.
In preferred embodiment of the utility model, said controller also comprises display unit, is connected with control module, shows the operation conditions of blower fan.
The beneficial effect of the utility model is: the utility model vent cabinet control system, and can, open at door blower fan when opening, residual exhaust gases in the vent cabinet is extracted out, guarantee test personnel's health, the while can be set the running time of blower fan, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the structural representation of the utility model vent cabinet control system one preferred embodiment;
The mark of each parts is following in the accompanying drawing: 100-door sensor, 200-controller, 210-control module, 220-timing unit, 230-input block, 300-blower fan contact-making switch, 400-blower fan.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the utility model embodiment comprises:
A kind of vent cabinet is controlled system; Comprise the door sensor 100, controller 200, blower fan contact-making switch 300 and the blower fan 400 that connect successively; Said controller 200 comprises control module 210 and timing unit that is connected with said control module respectively 220 and input block 230;
Said door sensor 100 is installed in the doorframe place, when door is opened, sends signal and gives control module; Door sensor 100 is the tongue tube sensor.
Said control module 210 is received the signal that door sensor 100 transmits, and control blower fan contact-making switch 300 is connected blower fan 400 entrys into service;
Said input block 230 comprises startup/stop button, time set button etc.; Can directly send the signal that starts blower fan 400 or stop blower fan 400 to control module 210; Simultaneously can also reinstate timing mode, set the time that starts or stops blower fan, realize control automatically;
Said timing unit 220 is received the commencing signal that control module 210 sends, and picks up counting, and arrives setting-up time, sends the signal that finishes and gives control module 210.
Preferably, controller 200 comprises that also display unit is connected with control module 210, can show the operation conditions of blower fan.
The utility model vent cabinet control system can open blower fan when door is opened, residual exhaust gases in the vent cabinet extracted out, and guarantee test personnel's health, the while can be set the running time of blower fan,, realize time opening or regularly close blower fan, energy-conserving and environment-protective.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
