Description
Technical field
The utility model relates to drying plant technical field, specifically refers to that a kind of preventing opens by mistake the baking oven opened.
Background technology
Baking oven is requisite drying plant in LED lamp bead production process, baking oven conventional in prior art is generally a conventional oven on sale on the market, this kind of baking oven can set drying time, auto-breaking is understood after drying the corresponding time, but, when drying time does not reach setting-up time also can people for opening baking oven.
In the workshop of carrying out LED lamp bead production, because employee is numerous, the equipment that different employee uses according to oneself and the difference of carrying out operation and need to carry out different product the oven dry of different time, if use, above-mentioned not reach setting-up time can people be also the baking oven opened, just very easily there is baking oven and open by mistake situation about opening, so not only certain danger is caused to the safety of whole workshop, and the cold air in the external world can pour in baking oven when baking oven is opened, bulk temperature in baking oven is declined to some extent, the utilization of impact heat, especially, this LED lamp bead repeatedly opens oven door in drying course, the product carrying out drying can be caused to be had a strong impact on, and then affect the luminous mass of LED lamp bead finished product.
Therefore, for the baking oven be applied at present in LED lamp bead workshop, await doing further improvement.
Utility model content
Technical problem to be solved in the utility model is the present situation for prior art, provides a kind of easy to use and can prevent from opening by mistake the baking oven opened.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of preventing opens by mistake the baking oven opened, comprise heating, temperature controller, rectifier, there is the door-plate that the casing of opening and rotation are arranged at box opening, described heating to be arranged on casing and to be controlled by temperature controller, the power input of described temperature controller is connected with rectifier, it is characterized in that: be provided with electromagnet and the suction block of the adhesive that matches with electromagnet at the opposite site of described door-plate and casing, be configured with the time relay simultaneously, be connected on the power output end of rectifier after the normally-closed contact of this time relay is connected in series with magnet spool.
As further improvement of the utility model, the top of described casing is provided with end face support triangular in shape near opening part, and the top of this support is opened wide and arranged and have an installation cavity, and described magnet spool is arranged in the installation cavity of above-mentioned support.Leg-of-mutton support has good steadiness, is arranged on by magnet spool in above-mentioned support and ensure that its fastness connected, to avoid because causing magnet spool to come off because of firmly excessive when staff opens by mistake and opens.
In such scheme, the top of described door-plate is provided with an installation portion positioned opposite with support, and described suction block is arranged on the sidewall of close support of installation portion.Adopt this structure, with make suction block can with magnet spool close contact, guarantee that the mistake open function of baking oven normally uses; Suction block in the utility model is iron block.
As preferably, the sidewall of described casing being provided with the ventilation mouth for connecting ventilating air pipe, this ventilation mouth being covered with one and can controlling the cover plate that ventilation mouth opens or closes, so that select as required whether to be connected with the external world by ventilating air pipe by baking oven.
For the ease of user's operation, the bottom of described casing is provided with control panel, and the described time relay and temperature controller are arranged on this control panel.
Compared with prior art, because the utility model is provided with electromagnet and the suction block of the adhesive that can match with electromagnet on the basis of a conventional oven, be provided with the time relay simultaneously, and be connected on the power output end of rectifier after the normally-closed contact of the time relay is connected in series with magnet spool, when using baking oven, set drying time, before this time terminates, the normally-closed contact of the time relay remains closed, the circuit connecting electromagnet coil keeps connected state, magnet spool sucks mutually with suction block, thus the door-plate of baking oven cannot be opened, open by mistake to prevent staff and open, after the drying time of setting terminates, the normally-closed contact of the time relay disconnects, and connects the circuit breaker of electromagnet coil, and the magnetic force on electromagnet coil disappears and loses suction to suction block, thus normally can open the door-plate of baking oven, the setting of said structure serves the effect preventing from baking oven from opening by mistake opening, and meanwhile, structure is simple, easy to use.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figures 1 to 3, the present embodiment prevent open by mistake the baking oven opened comprise heating (not shown), temperature controller TC, rectifier RECT, the time relay, electromagnet, have opening casing 1 and rotate and be arranged at the door-plate 2 of casing 1 opening part.Heating to be arranged on casing 1 and to be controlled by temperature controller TC, and after switching on power, heating can heat casing 1.The top of casing 1 is provided with end face support triangular in shape 12 near opening part, and the top of this support 12 is opened wide and arranged and have an installation cavity 121, and magnet spool L is arranged in the installation cavity 121 of support 12.The power input of temperature controller TC is connected with rectifier RECT; The power input of rectifier RECT is connected with the output of AC power, is connected on the power output end of rectifier RECT after the normally-closed contact SJ of the time relay is connected in series with magnet spool L.Above-mentioned rectifier RECT the alternating current of 220V is converted to the direct current of 24V and supply company is connected to the circuit of electromagnet coil L.Door-plate 2 is provided with the suction block 3 relative with electromagnet coil L position, the suction block 3 in the present embodiment is iron block.When using the baking oven of the present embodiment, set drying time, before this time terminates, the normally-closed contact SJ of the time relay remains closed, the circuit connecting electromagnet coil L keeps connected state, magnet spool L sucks mutually with suction block 3, thus the door-plate 2 of baking oven cannot be opened, and opens by mistake open to prevent staff; After the drying time of setting terminates, the normally-closed contact SJ of the time relay disconnects, and connects the circuit breaker of electromagnet coil L, and the magnetic force on electromagnet coil L disappears and loses suction to suction block 3, thus normally can open the door-plate 2 of baking oven; The baking oven of the present embodiment has and prevents from opening by mistake the effect of opening, and meanwhile, structure is simple, easy to use.
In the present embodiment, the top of door-plate 2 is provided with an installation portion 21 positioned opposite with support 12, suction block 3 is arranged on the sidewall of close support 12 of installation portion 21, with make suction block 3 can with magnet spool L close contact, guarantee that the mistake open function of baking oven normally uses.The sidewall of casing 1 being provided with the ventilation mouth 13 for connecting ventilating air pipe, this ventilation mouth 13 being covered with one and can controlling the cover plate that ventilation mouth 13 opens or closes, so that select as required whether to be connected with the external world by ventilating air pipe by baking oven.For the ease of user's operation, the bottom of casing 1 is provided with control panel 4, and the time relay and temperature controller TC are arranged on this control panel.
