Abstract
The utility model discloses a kind of electric dry oven preengaging control start and stop, comprise and be installed in the electric heating element in electric dry oven and the attemperating unit for controlling electric heating element work, attemperating unit comprises and connects power supply and the relay of electric heating element and the temperature controller for control relay start and stop, is connected in series with a microcomputer time-controlled switch in the circuit that temperature controller is connected with power supply.The utility model temporally can preengage start and stop, and with setting-up time section circulating start and outage, or can carry out the time reservation control start and stop of multi-period control start and stop.
Description
Technical field
The utility model relates to appliance field, is specifically related to a kind of electric dry oven preengaging control start and stop.
Background technology
At present, existing time control electric dry oven can only stop after the time of setting, can not accomplish that reservation starts, and more to circulate in sky or week and the start and stop of multi-period control circuit, can not can not meet the user's needs having this respect demand.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiency that prior art exists, and provides one temporally can preengage start and stop, and can with setting-up time section circulating start and outage, or carry out the electric dry oven of preengage control start and stop of multi-period control start and stop.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of electric dry oven preengaging control start and stop, comprise and be installed in the electric heating element in electric dry oven and the attemperating unit for controlling electric heating element work, described attemperating unit comprises and connects power supply and the relay of electric heating element and the temperature controller for control relay start and stop, is connected in series with a microcomputer time-controlled switch in the circuit that described temperature controller is connected with power supply.
As further improvement of the utility model:
The power input of described microcomputer time-controlled switch is connected with power supply, and the power output end of described microcomputer time-controlled switch is connected with the power input of temperature controller, and the power output end of described temperature controller is connected with the pull-in winding end points of relay.
Described electric heating element is heating wire.
Compared with prior art, the utility model has the advantage of: the utility model can be preengage the electric dry oven controlling start and stop and pass through to be connected in series with a microcomputer time-controlled switch in the circuit be connected with power supply at temperature controller, the opening and closing of temperature controller is controlled by microcomputer time-controlled switch, again by the start and stop of temperature controller control relay, finally reach and control the object of electric dry oven according to setting-up time start and stop, temporally can preengage start and stop, and can with setting-up time section circulating start and outage, or carry out multi-period control start and stop, use very convenient, the different needs of user can be met.The structure of this electric dry oven is simple, safe and reliable, be easy to improve and implement.

Fig. 1 is the circuit theory diagrams that the utility model can preengage the electric dry oven controlling start and stop.
Marginal data:
1, electric heating element; 2, power supply; 3, relay; 4, temperature controller; 5, microcomputer time-controlled switch.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model can preengage the electric dry oven controlling start and stop, comprise and be installed in the electric heating element 1 in electric dry oven and the attemperating unit for controlling electric heating element 1 work, attemperating unit comprises and connects power supply 2 and the relay 3 of electric heating element 1 and the temperature controller 4 for control relay 3 start and stop, a microcomputer time-controlled switch 5 is connected in series with in the circuit that temperature controller 4 is connected with power supply 2, this microcomputer time-controlled switch 5 is prior art, and buyable obtains.The power input of microcomputer time-controlled switch 5 is connected with power supply 2, and the power output end of microcomputer time-controlled switch 5 is connected with the power input of temperature controller 4, and the power output end of temperature controller 4 is connected with the pull-in winding end points of relay 3.
Control temperature controller 4 by microcomputer time-controlled switch 5 to be switched on or switched off with power supply 2, the start and stop of temperature controller 4 control relay 3 again, thus electric heating element 1 and power supply 2 are switched on or switched off, finally reach and control the object of electric dry oven according to the start and stop of microcomputer time-controlled switch 5 setting-up time.
In the present embodiment, electric heating element 1 is heating wire, and in other embodiments, electric heating element 1 also can be the electrical heating components and parts such as electric heating tube.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment.For those skilled in the art, do not departing from the improvement that obtains under the utility model technical conceive prerequisite and conversion also should be considered as protection domain of the present utility model.
