The utility model can automatically identify direct current power supply and the dry battery power supply, and has the advantages of convenient installation and operation, without operation, and secure and reliable complete machine, etc.

Description

Gas kitchen ranges with AC and DC auto-conversion function
Technical field
The utility model relates to gas kitchen ranges, especially relates to a kind of being installed on the household gas utensils, can adopt two kinds of power supply modes of alternating current 220V civil power and dry cell, and can change the gas kitchen ranges of two kinds of power supplies automatically.
Background technology
Along with gas kitchen ranges constantly popularizing in family cooking, people are also increasing to the use amount of battery, and the frequent battery that renews, and bring inconvenience for people's life; And take still abandoning of used batteries in a large number and brought serious destruction to environment.The scope of application of electric main constantly expands to many fields, has wherein also entered the power supply field of our kitchen range, still, will cause the work of kitchen range complete machine in paralyzed state if having a power failure.At above-mentioned situation, this has the gas-cooker of AC and DC auto-conversion function to have designed the utility model, this utility model is as increased by one " have a power failure and protect " for gas kitchen ranges, allow people can use kitchen range at any time, the restriction that is not had a power failure and bring, but also greatly reduce the use amount of dry cell.
The utility model content
Whether the purpose of this utility model provides a kind of alternating current of can discerning and supplies with, thereby controls the break-make of dry cell automatically, and the gas kitchen ranges with Alternating Current Power Supply, powered battery two states auto-conversion function easy to use, safe.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of gas kitchen ranges with AC and DC auto-conversion function, kitchen range comprise panel, center distributor, outer shroud distributor, drain pan, battery case, the automatic switching controller of AC and DC is installed on kitchen range, the automatic switching controller of described AC and DC connects battery and kitchen range ignition in the battery case respectively by lead, also is provided with ac power plug by lead on the automatic switching controller of described AC and DC.The AC and DC automatic switch is installed on kitchen range, 220V alternating current and dry cell power supply are as the input of the automatic switching controller of AC and DC, by the needed supply voltage of inside identification control back output point firearm of automatic switching controller, thereby play the purpose that two kinds of power supply modes of gas kitchen ranges are controlled automatically.
The major control element of the automatic switching controller of described AC and DC is AC relay or DC relay.
The automatic switching controller of described AC and DC is made of discrete component.
Battery in the described battery case is dry cell or rechargeable battery.
Whether the automatic switching controller of the AC and DC in this programme is installed on the kitchen range, have a power failure in case plug just can judge behind the ac plug.If have a power failure, relay contact is in closure state, connects the dry cell power supply branch road, is the igniter normal power supply; If do not have a power failure, relay contact is in off-state, promptly disconnects the dry cell power supply branch road, and be exactly dc source 220V AC power process transformation, rectification, filtering, voltage stabilizing after for the igniter power supply this moment.
The utility model has the advantages that: the automatic switching controller of AC and DC can be installed on any position of gas kitchen ranges, realize the power supply of dual mode, and can discern the 220V alternating current automatically and whether have a power failure, also can not cause the interruption of kitchen range work even if having a power failure.During use, as long as plug in plug, do not need other any operations, the automatic switching controller of AC and DC just can judge automatically whether alternating current powers, if alternating current has power supply, thereby the electric weight of dry cell has been saved in the automatic disconnection of dry cell branch road; If AC outage, the dry cell branch road is connected automatically, has guaranteed that kitchen range work can't not work because of power failure.In addition, the utlity model has installation, easy to use, need not operation, complete machine safety, advantage such as reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a circuit diagram of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is further described:
The utility model is a kind of friendship, the structure of the gas kitchen ranges of the automatic switching controller of direct current is as shown in Figure 1: mainly by panel 1, center distributor 2, outer shroud distributor 3, pan bracket 4, drain pan 5, burner 6, hand over, the automatic switching controller 7 of direct current, inductive needle 8, spray point 9, magnetic valve 10, kitchen range ignition switch 11, kitchen range ignition 12, drip pan 13 and battery case 14 constitute, wherein on kitchen range drain pan 5, friendship can be installed, the automatic switching controller 7 of direct current, hand over, the automatic switching controller of direct current connects battery and kitchen range ignition 12 in the battery case 14 respectively by lead, hand over, also be provided with ac power plug by lead on the automatic switching controller of direct current, hand over, the automatic switching controller 7 of direct current has the power supply of dual mode, can change two kinds of power supplies of alternating current 220V mains-supplied and dry cell power supply automatically, can also discern the 220V alternating current automatically and whether have a power failure, also can not cause the interruption of kitchen range work even if having a power failure.The automatic switching controller 7 of this AC and DC can be AC relay or DC relay, also can be made of discrete component.Be that automatic conversion in the automatic switching controller 7 of AC and DC and automatic identification circuit can adopt relay control of the prior art, also can adopt discrete component to realize control.Battery in the described battery case is dry cell or rechargeable battery.During use, as long as plug in plug, do not need other any operations, the automatic switching controller of AC and DC just can judge automatically whether alternating current powers.If have a power failure, relay contact is in closure state, connects the dry cell power supply branch road, is the igniter normal power supply; If do not have a power failure, relay contact is in off-state, promptly disconnects the dry cell power supply branch road, thereby has saved the power consumption of dry cell, and be exactly dc source 220V AC power process transformation rectifying and wave-filtering voltage stabilizing after for the igniter power supply this moment.
As long as this utility model can be used for ion induction type or thermojunction type puts out the kitchen range that need the power supply power supply of protecting function.
In Fig. 2,220V alternating current and dry cell power supply are as the input of the automatic switching controller of AC and DC, by the needed supply voltage of inside identification control back output point firearm of automatic switch.As long as plug in plug, do not need other any operations, the automatic switching controller of AC and DC just can judge automatically whether alternating current powers.If have a power failure, the contact of relay K is in closure state, connects the dry cell power supply branch road, is the igniter normal power supply; If do not have a power failure, the contact of relay K is in off-state, promptly disconnect the dry cell power supply branch road, thereby saved the power consumption of dry cell, be exactly dc source 220V AC power pass through transformation (by T1 finished), rectifying and wave-filtering voltage stabilizing (by D1, D2, D3, D4, C1, C2, C3, C4, C5, C6, D7, U2 etc. finished) after for igniter power supply this moment.The automatic identification alternating current of circuit diagram 2 repeat circuits whether have with exchange, the direct current auto-conversion function also can be realized by discrete component.
