Abstract
The invention relates to a secure gas water heater adopting a direct-current power source. The water heater at least comprises a direct-current fan or further comprises a water pump, wherein a power adapter 2 is connected between a gas water heater 1 and an external power source 3, the power adapter 2 is used for converting alternating current of the external power source into direct current; a water pump motor is a direct-current motor; and the gas water heater electrically controls required voltage so as to be adapted to the direct-current voltage provided by the power adapter. The secure gas water heater has the following benefits: first, the adoption of the direct-current power source not only can realize secure power utilization, but also can simplify the structure of the gas water heater, including the structure of an electric control system, and can remarkably lower design, production, test and detection expenses; second, the secure gas water heater can be adapted to the requirement of frequency conversion of fans and water pump motors, so as to form a serial energy-saving environment-friendly variable-frequency gas water heater, and the market prospect is wide; and third, the secure gas water heater is applicable to not only domestic quick gas water heaters, but also other types of gas water heaters including a fan or a water pump, thus being wide in use.
Description
Technical field
The present invention relates to gas heater, especially with the gas heater of external power supply.
Background technology
Equipped with blower fan or the gas heater that is also equipped with water pump, external power supply need to be used to power；Existing forced exhaust formula gas heater, being forced to exhaust fuel gas water heater, be typically all and use electrical network to power, according to national, regional difference, the rated voltage that electrical network is powered is usually 220V, 110V, is alternating current.Owing to using non-security voltage, the Electrical Safety problem of gas heater is seemed particularly significant, for this, in internal structure design, including the design of electric part, it is both needed to Electrical Safety is carried out particular design, and the electrical safety need to being correlated with gas heater is tested, tests, verified.Using non-security voltage, it is not only possible to cause Electrical Safety problem, and make the design cost of the electric part of gas heater, manufacturing cost all can increase accordingly, the test of gas heater, test, manufacturing cost are also the biggest.
In existing gas heater, having and use DC frequency-changing blower fan technology, use this technology, alternating current must be converted to unidirectional current, cost can increase accordingly undoubtedly.For the gas heater equipped with water pump, pump motor uses alternating current, be allowed to realize energy-saving and frequency-variable, it is clear that more difficulty.
Should ensure gas heater safety in electricity consumption, can substantially reduce the design of gas heater, manufacturing cost again, and adapt to fan of gas water heater, the needs of pump motor frequency conversion, this is to use external power supply gas heater development problem encountered.
Summary of the invention
The safety gas water heater using DC source puts forward for the problems referred to above just, pass through the present invention, the external power supply voltage being possible not only to make gas heater is down to DC voltage safe to the human body by alternating voltage, and the design of gas heater, manufacturing cost can be significantly reduced, and adapt to the needs of motor, fan frequency conversion.
According to the difference of gas heater purposes, the present invention can be realized respectively by following two technical scheme:
First technical scheme: use the safety gas water heater of DC source, it at least includes DC fan, connects the wire of external power supply, particularly, between gas heater and external power supply, being also associated with power supply adaptor, the alternating current of external power supply is converted to unidirectional current by power supply adaptor.
Second technical scheme: use the safety gas water heater of DC source, it at least includes DC fan, the water pump of translator, the wire of connection external power supply, particularly, between gas heater and external power supply, being also associated with power supply adaptor, the alternating current of external power supply is converted to unidirectional current by power supply adaptor；Described water pump, its motor is direct current generator.
More specifically, in above-mentioned two technical scheme, the voltage of described power supply adaptor output is unidirectional current, and its voltage sets according to the voltage needed for blower fan or pump motor, or select in 12～36V scopes, its electric current sets according to the electric power of gas heater；The DC voltage that voltage needed for gas heater electric control system and power supply adaptor are provided adapts；Described gas heater is provided with the power connection structure adapted with power supply adaptor；Described power connection structure, at least includes that USB plug, socket connecting structure, described USB socket are arranged in gas heater main body.
There is advantages that
First, use DC source, be possible not only to realize Electrical Safety, and gas heater structure can be simplified, including electric control system structure, significantly reduce design, manufacture, test, testing cost；
Second, it is adapted to blower fan and the needs of pump motor frequency conversion, forms series energy-saving, environment-friendly type frequency conversion type gas heater, wide market；
3rd, not only it is adapted to domestic fast gas heater, is also applied for containing blower fan or possibly together with the other types gas heater of water pump, of many uses.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the present invention.
