Description
Technical field
The utility model belongs to experimental apparatus technical field, and in particular to a kind of logically true automatic heating drying oven of reciprocal of duty cycle.
Background technology
Vacuum drying chamber, for drying thermal sensitivity, easily decomposition and readily oxidizable substance, it is particularly the article of some complicated components
Can rapid draing.But the vacuum drying chamber used at present has following drawback：One is vavuum pump is constantly in prolonged work
Make state, while a large amount of electric energy are lost, service life can also shorten；The second is press computer heating control button after vacuumizing manually again
Case heating is dried, so can be cumbersome, often it is same with heat button to vacuumize button in order to save the time by operating personnel
When press, allow and drying box pumped vacuum systems and heating system while run, so operation can be very dangerous, because gas heat is swollen
Swollen, because the sealing of drying box is very good, immense pressure caused by expanding gas is there is a possibility that observation window safety glass is quick-fried
Split, it is dangerous larger；Third, when the gas of heating is gone by vacuum pumped, heat will necessarily be brought in vavuum pump, from
And cause vavuum pump temperature rise too high, decline the vacuum efficiency of pump.
Utility model content
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of reasonable in design, dry beneficial to improving
The service life of dry case and vavuum pump, the automatic heating drying oven of logically true reciprocal of duty cycle for ensureing processing safety.
To realize above-mentioned technical purpose, the utility model uses following technical scheme：
The logically true automatic heating drying oven of reciprocal of duty cycle, including oven main body, power switch is provided with the oven main body；It is described
Oven main body is internally provided with electric heater unit, and the oven main body is externally connected to vacuum extractor；On the oven main body
The pressure sensor of pressure in the temperature sensor and detection baking oven of detection oven temperature is provided with, is gone back on the oven main body
It is provided with the temperature, pressure control unit being connected with the temperature sensor, the pressure sensor signal, the temperature, pressure
The signal output part control connection heater switch and pressure switch of control unit, the heater switch are electrically connected with the electrical heating
Device, the pressure switch are electrically connected with the vacuum extractor.
Preferably, the vacuum extractor includes the vacuum tube connected with the oven main body inner chamber, the vacuum tube
It is connected with vavuum pump.
Due to there is at least following beneficial effect using above-mentioned technical proposal, the utility model：When vacuum pressure in baking oven
After reaching setting value, electric signal is sent into temperature, pressure control unit, temperature, pressure control unit output signal by pressure sensor
Control the switch of electric heater unit and vacuum extractor.The utility model is designed reasonably, improve making for drying box and vavuum pump
With the life-span, operational danger is avoided.
Brief description of the drawings
The following drawings is only intended to, in doing the utility model schematic illustration and explanation, not limit model of the present utility model
Enclose.Wherein：
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only pass through
Bright mode describes some one exemplary embodiments of the present utility model.Undoubtedly, one of ordinary skill in the art can be with
Recognize, can be with a variety of modes to described in the case of without departing from spirit and scope of the present utility model
Embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claim
Scope.
As shown in figure 1, the logically true automatic heating drying oven of reciprocal of duty cycle, including oven main body 1, it is provided with the oven main body 1
Power switch 2；The oven main body 1 is internally provided with electric heater unit (not shown), can use electrical heating wire etc. often
Realized with structure；The oven main body 1 is externally connected to vacuum extractor；The vacuum extractor includes and the oven main body
The vacuum tube 3 of 1 inner chamber connection, the vacuum tube 3 are connected with vavuum pump 4；Temperature in detection baking oven is provided with the oven main body 1
The pressure sensor 6 of pressure in the temperature sensor 5 of degree and detection baking oven, it is additionally provided with and the temperature on the oven main body 1
Sensor 5, the temperature, pressure control unit 7 of the signal of the pressure sensor 6 connection are spent, the temperature, pressure control unit 7
Signal output part control connection heater switch 8 and pressure switch 9, the heater switch 8 are electrically connected with the electric heater unit, institute
State pressure switch 9 and be electrically connected with the vacuum extractor, wherein temperature, pressure control unit 7 can use known in the prior art
General knowledge realizes its control function, is no longer repeated herein.
In the present embodiment, the oven main body 1 is made up of Steel material, is hinged on the oven main body 1 and is provided with oven door
10, door handle 11 and security window 12 are provided with the oven door 10.
After vacuum pressure reaches setting value in baking oven, electric signal is sent into temperature, pressure control unit by pressure sensor 6
7, the output signal of temperature, pressure control unit 7, heater switch 8 controls electric heater unit to open, while the control of pressure switch 9 is taken out very
Empty device stops, and the problem of avoiding pumped vacuum systems and heating system while run, improves making for drying box and vavuum pump
With the life-span, pumped vacuum systems and heating system while the danger of operation are avoided.
The schematical embodiment of the utility model is the foregoing is only, is not limited to model of the present utility model
Enclose.Any those skilled in the art, it is made on the premise of design of the present utility model and principle is not departed to be equal
