Description
Technical field
This novel genus heating electromagnetic oven field relates in particular to the heating power Circuit tuning of electromagnetic oven.
Background technology
Electromagnetic oven applies on passenger train widely, to satisfy passenger and crew member's dietary requirements.But in use exist two shortcomings: the one, owing to can not realizing 360 degree adjustings, cause and can not directly be adjusted to maximum power, increased the complexity of operation, reduced operating efficiency; The 2nd, owing to being in for a long time under hot and humid environment for use, cause Power Conditioning Unit short useful life.
The utility model content
The utility model purpose be to provide a kind of can freely regulated train electromagnetic oven power conditioning circuitry.
This device is mainly used in electromagnetic oven, realizes the function that electromagnetic oven power is regulated.Formed by parts such as wiring board, band switches, wiring board and band switch are used in conjunction with, when at 0 grade, 0 contact conducting of band switch, output switching signal is to the electromagnetic oven main frame, when gear is adjusted to 1 ~ 7, and 1 ~ 7 contact conducting of band switch, the output potential signal is realized the adjusting of the power of electromagnetic oven.
The technical solution of the utility model is: a kind of train electromagnetic oven power conditioning circuitry, foregoing circuit comprises resistance and band switch, switching signal by resistance R 1 receive+the 5V power supply on, by band switch contact 1,2 ground connection; The resistor network that resistance R 2 ~ R8 is composed in series, the node between series resistance are connected with the contact 4 ~ 10 of band switch respectively, and the Power Regulation signal is connected with the contact 3 of band switch.Above-mentioned R2 ~ R8 can be substitutional resistance, also can select difference resistance.
The utlity model has dependable performance, with low cost, can realize 360 degree adjustings, the advantages such as handled easily adopt hermetic element, and wiring board is carried out insulation processing, guaranteed outside normal the use, to have extended useful life to greatest extent under hot and humid environment.Can realize linear regulation according to the demand of reality, also can realize Nonlinear Adjustment, satisfy the demand of various working.
Description of drawings
Fig. 1 is this novel system circuit diagram.
Embodiment
This Novel electric routing resistance and band switch form, switching signal by pull-up resistor R1 receive+the 5V power supply on, and by band switch contact 1,2 ground connection, when contact 1,2 conducting, electromagnetic oven be described just at holding state, the electromagnetic oven inactivity is exported.
The resistor network that is composed in series by resistance R 2 ~ R8, node between series resistance is connected with the contact 4 ~ 10 of band switch respectively, the Power Regulation signal is connected with the contact 3 of band switch, thereby realize that band switch collects different potential values at different gears, and then carry out the power adjustments of electromagnetic oven.In the resistance network of series connection, R2 ~ R8 can be substitutional resistance, can realize linear regulation, if R2 ~ R8 selects difference resistance, can realize Nonlinear Adjustment, thereby satisfy the demand of various working.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
