Description
The present invention relates to a kind of micro-wave oven, especially use the micro-wave oven of the car special use of dc source.
Common microwave stove is as a kind of cooking appliance, is typically designed to by AC power to drive.But when taking car and go out, the field can not connect AC power whenever and wherever possible, therefore can not use micro-wave oven easily.And if adopt battery on the car as power supply because accumulator electric-quantity is limited, its discharge fully can make the work in micro-wave oven source interrupt, and also can influence normally travelling of car.
The purpose of this invention is to provide a kind of micro-wave oven that can use with car, do not having under the situation of AC power also cooking food easily; Simultaneously, can prevent that again battery from discharging fully.
The technical solution used in the present invention is as follows:
In the electric chamber of common microwave stove, install one additional dc source is transformed to the rectifier of AC power, the dc source of its input termination dolly, the elementary line chart of output termination high-tension transformer.
Commutator and 4 brushes that contact with the outer surface of commutator respectively that described rectifier comprises the micro machine that produces revolving force, driven by micro machine.This commutator comprises the cylinder of being made by insulating materials, and be formed on current-carrying part on this cylinder outer surface, the insulated part that this current-carrying part is had preset width separates into even number, and contact with two brushes adjacent one another are respectively, the width of described each insulated part is all more than or equal to the end width of brush.A pair of brush respect to one another is connected with the dc source of dolly, and respect to one another another links to each other with high-tension transformer to brush.Micro machine and wherein that a pair of brush parallel connection that is connected the dolly dc source.In addition, between each brush adjacent one another are, be connected with the diode that is used to prevent backward voltage respectively.
This micro-wave oven also is equipped with the device that detects and show remaining battery voltage, and it comprises voltage detector, microprocessor, display and power supply relay.When magnitude of voltage was lower than rated value, microprocessor promptly stopped the operation of micro-wave oven.
The input DC power of this micro-wave oven is pegged graft at dolly cigar lighter place.
The present invention can make common microwave stove especially use on car there not being AC power to have only cooking food under the situation of dc source owing to installed the rectifier that dc source is transformed to AC power additional, not only economy but also convenient; Owing to installed the device that detects and show remaining battery voltage additional, can prevent that battery from discharging fully, and influence normally travelling of car again.
Be described in further detail the present invention below in conjunction with drawings and Examples.
Fig. 1 is the circuit diagram of one embodiment of the present of invention;
Fig. 2 and Fig. 3 show the course of work that the present invention is transformed into dc source AC power;
Fig. 4 has installed the block diagram that detects and show the embodiment of remaining battery voltage device additional.
In Fig. 1.Rectifier 1 comprises micro machine 1-1,4 brush 1-21,1-22,1-23,1-24 and commutator 1-3, and each brush contacts with the outer surface of commutator 1-3, and commutator 1-3 is driven by micro machine 1-1.High-tension transformer 2 comprises a primary coil 2-1, one first secondary coil 2-21 and a second subprime coil 2-22, and primary coil 2-1 is around the importation, and the first and second secondary coil 2-21,2-22 are around output.The dc source of dolly is provided to rectifier 1 by power supply relay J, here, a pair of brush 1-21 respect to one another is connected with dc source DC with 1-23, another is connected with the primary coil 2-1 of high-tension transformer 2 with 1-24 brush 1-22 respect to one another, is used to prevent that 4 diode D1, D2, D3, D4 of backward voltage are connected between adjacent each brush 1-21,1-22,1-23, the 1-24.Micro machine 1-1 and that a pair of brush 1-21, the 1-23 parallel connection that are connected the dolly dc source.Therefore, when power supply relay J connected, dc source was provided to brush 1-21,1-23 and micro machine 1-1.Capacitor C is in parallel with power supply relay J.Commutator 1-3 comprises a cylinder 1-31 and is formed on current-carrying part 1-32 on the outer surface of cylinder 1-31, and the insulated part 1-33 that this current-carrying part 1-32 is had preset width is divided into even number, and is connected with adjacent two brushes respectively.High-voltage capacitor HVC, high-voltage diode HVD are connected with second subprime coil 2-22 with the first secondary coil 2-21 of high-tension transformer 2 with magnetron MGT, and its structure is identical with prior art with operating process.
The course of work that microwave oven for automobile dc source of the present invention is transformed into AC power as shown in Figures 2 and 3.
In Fig. 2, electric current is input to top brush 1-21 from the anode of dc source, and flow towards top from the bottom of primary coil 2-1 through the current-carrying part 1-32 of commutator 1-3 and left side brush 1-22, be input to the brush 1-24 on the right again and flow back into the negative terminal of dc source through current-carrying part 1-32 and bottom brush 1-23.
In Fig. 3, commutator 1-3 turns over 90 degree clockwise, electric current is input to top brush 1-21 from the anode of dc source, and flow towards the bottom from the top of primary coil 2-1 through the current-carrying part 1-32 of commutator 1-3 and the right brush 1-24, be input to the brush 1-22 on the left side again and flow back into the negative terminal of dc source through current-carrying part 1-32 and bottom brush 1-23.
Therefore, 12V dc source from the car battery is pegged graft at the cigar lighter place, offer micro machine 1-1 and top brush 1-21 through power supply relay J, capacitor C charge or discharge one voltage in parallel with power supply relay J, cause micro machine 1-1 in initial operation, to rotate smoothly, driving commutator 1-3 rotates, its current-carrying part 1-32 successively with each brush 1-21,1-22,1-23, the 1-24 contact, commutator 1-3 rotates a circle, the sense of current among the primary coil 2-1 of high-tension transformer 2 changes twice up and down successively, thereby dc source is become the AC power of required frequency.High-tension transformer 2 will be provided to the AC power of primary coil 2-1 and sense the first and second secondary coil 2-21,2-22.The first secondary coil 2-21 preheating magnetron MGT, the supply voltage that second subprime coil 2-22 will be input to primary coil 2-1 is elevated to about 2000V, arrive about 4000V through high-voltage capacitor HVC and kenetron HVD multiplication of voltage again, be provided to magnetron MGT then, from the microwave of magnetron generation 2450MHz, the food in furnace chamber is promptly by microwave cooking.
In Fig. 4, rectifier 1, high-tension transformer 2, the structure of magnetron MGT is identical with embodiment shown in Figure 1 with operation, increased and be used to the device 3 that detects the residual voltage of dc source and show its voltage, it comprises a voltage detector 3-1, a microprocessor 3-2, a display 3-3 and a power supply relay 3-4, voltage detector 3-1 is with detected magnitude of voltage input microprocessor 3-2, microprocessor 3-2 shows magnitude of voltage by display 3-3, if this magnitude of voltage is lower than rated value, then power supply relay 3-4 is disconnected by microprocessor 3-2, cause this microwave oven for automobile to quit work, keep the residual voltage of battery, prevent the discharge fully of battery, unlikelyly influence normally travelling of car.
Certainly, rectifier among the present invention and remaining battery voltage detecting display unit are also separable outside this micro-wave oven, and do not influence its use, should belong to protection scope of the present invention equally.
