Description

Gas cooker with automatic conversion function of AC and DC

technical field

The utility model relates to a gas cooker, in particular to a gas cooker installed on a household gas cooker, which can adopt two power supply modes of AC 220V commercial power and a dry battery, and can automatically switch between the two power supply sources.

Background technique

With the continuous popularization of gas cookers in home cooking, people use more and more batteries, and frequently replace new batteries, which brings a lot of inconvenience to people's lives; and a lot of old batteries are still discarded to the environment. caused serious damage. The scope of use of AC mains power has continuously expanded to many fields, and it has also entered the power supply field of our cooker. However, if there is a power failure, the work of the cooker will be paralyzed. In view of the above situation, this utility model has been designed with the function of automatic conversion of AC and DC gas cooker. This utility model is like adding a "power failure protection" to the gas cooker, so that people can use the cooker at any time without being affected by power failure. To the constraints, but also greatly reduce the use of dry batteries.

Utility model content

The purpose of the utility model is to provide a gas cooker that can identify whether the AC power is supplied, thereby automatically controlling the on-off of the dry battery, and is easy to use and safe, and has the function of automatic switching between AC power supply and battery power supply.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a gas cooker with AC and DC automatic conversion functions, the cooker includes a panel, a central fire distribution device, an outer ring fire distribution device, a bottom case, and a battery box, and a gas cooker is installed on the cooker AC and DC automatic conversion controllers, the AC and DC automatic conversion controllers are respectively connected to the battery in the battery box and the electronic igniter of the cooker through wires, and the AC and DC automatic conversion controllers are also provided with AC power plugs through wires . Install AC and DC automatic converters on the cooker, 220V AC and dry batteries are used as the input of AC and DC automatic conversion controllers, and output the power supply voltage required by the igniter after the internal identification and control of the automatic conversion controllers, so as to play a role in The purpose of automatic control of the two power supply modes of the gas cooker.

The main control element of the AC-DC automatic conversion controller is an AC relay or a DC relay.

The AC and DC automatic conversion controller is composed of discrete components.

The batteries in the battery box are dry batteries or rechargeable batteries.

The AC and DC automatic conversion controller in this scheme is installed on the cooker, once the AC plug is plugged in, it can be judged whether there is a power failure. If there is a power failure, the relay contacts are in the closed state, and the dry battery power supply branch is connected to supply power to the igniter normally; It is the DC power supply after the 220V AC power supply has been transformed, rectified, filtered, and stabilized.

The utility model has the advantages that the AC and DC automatic conversion controller can be installed on any position of the gas cooker to realize two ways of power supply, and can automatically identify whether the 220V AC power is cut off, even if there is a power cut, it will not cause the cooker to work interruption. When using, just plug in the power plug without any other operation, the AC and DC automatic conversion controller can automatically judge whether the AC power is supplied, if the AC power is supplied, the dry battery branch is automatically disconnected to save the power of the dry battery; if In case of AC power failure, the branch circuit of the dry battery is automatically connected, which ensures that the cooking range does not fail to work due to power failure. In addition, the utility model has the advantages of convenient installation and use, no operation, safety and reliability of the whole machine.

Detailed ways

The utility model will be further described below in conjunction with implementation examples:

The utility model is a gas cooker with an AC and DC automatic conversion controller. 6. AC and DC automatic conversion controller 7, induction needle 8, discharge needle 9, solenoid valve 10, cooker ignition switch 11, cooker electronic igniter 12, liquid storage tray 13 and battery box 14, wherein the cooker bottom shell 5 AC and DC automatic conversion controllers 7 can be installed on the top, and the AC and DC automatic conversion controllers are respectively connected to the battery in the battery box 14 and the electronic igniter 12 of the cooker by wires, and the AC and DC automatic conversion controllers are also provided with AC Power plug, AC and DC automatic switching controller 7 has two power supply modes, which can automatically switch between AC 220V mains power supply and dry battery power supply, and can also automatically identify whether the 220V AC power is out of power, even if there is a power outage, it will not cause damage. Interruption of hob operation. The AC-DC automatic conversion controller 7 can be an AC relay or a DC relay, and can also be composed of discrete components. That is, the automatic switching and automatic identification circuits in the AC and DC automatic switching controller 7 can be controlled by relays in the prior art, or can be controlled by discrete components. The batteries in the battery box are dry batteries or rechargeable batteries. When in use, as long as the power plug is plugged in, the AC and DC automatic conversion controller can automatically judge whether the AC power is supplied without any other operations. If there is a power failure, the relay contacts are in the closed state, and the dry battery power supply branch is connected to supply power to the igniter normally; if there is no power failure, the relay contacts are in the open state, that is, the dry battery power supply branch is disconnected, thereby saving the power consumption of the dry battery At this time, the power supply for the igniter is the DC power supply after the 220V AC power supply has been transformed, rectified, filtered and stabilized.

The utility model can be used for cooking ranges with an ion induction type or a thermocouple type extinguishing protection function as long as they need power supply.

In Figure 2, 220V AC and dry battery power supply are used as the input of the AC and DC automatic conversion controller, and the power supply voltage required by the igniter is output after the internal identification and control of the automatic converter. As long as the power plug is plugged in, without any other operation, the AC and DC automatic conversion controller can automatically judge whether the AC power is supplied. If there is a power failure, the contacts of relay K are in the closed state, and the dry battery power supply branch is connected to supply power to the igniter normally; if there is no power failure, the contacts of relay K are in the open state, that is, the dry battery power supply branch is disconnected, thereby saving The power consumption of the dry battery, at this time, the 220V AC power supply for the igniter is transformed (by T1), rectified and filtered (by D1, D2, D3, D4, C1, C2, C3, C4, C5, C6, D7, U2, etc. completed) DC power supply. In the circuit diagram 2, the relay's automatic recognition of whether there is alternating current and the automatic conversion function of alternating current and direct current can also be realized by discrete components.
