Abstract

The utility model relates to a split-type gas water-heater, comprising a hot water body and a controller, wherein, the hot water body is connected with the controller by a pipeline, the hot water body is composed of an underframe, a hot water pipe with a water inlet port and a water outlet port, a combustor and a casing body, the combustor is arranged on the underframe, and the casing body is composed of an inner cover, a thermal insulating cover, and an outer cover. The water heater adopting a spiral heating pipe improves the structure of the existing hot water body of the water heater, and has the advantages of high thermal efficiency and convenient operation, and when installed, a heating body can be arranged out of doors for eliminating an existing hidden trouble produced by gas poisoning. The water heater can generally replace the existing gas water heaters of different forms.

Description

Split type gas heater

The utility model relates to a kind of gas heater, is home-use hot water facility, particularly a kind of split type gas heater.

Existing gas heater is not outer in following two kinds of versions: a kind of is the manual ignition water heater, in use, open burnt gas switch earlier, light a fire then, must open water inlet switch simultaneously, use trouble, the air inlet of Gas Pipe switch opens is to this process of manual ignition, once-existing difference, waste combustion gas easily causes the generation of gas explosion accident on the other hand easily on the one hand; Another kind of for having the gas heater of the fire control igniting and the defencive function of cutting off the water.The water temperature flow-control of the water heater of these two kinds of structures all is located at (promptly integrated) on the hot water, can't regulate water temperature and flow arbitrarily in use at all, for easy to use, mostly water heater is installed in the bathroom, produce a large amount of pernicious gases such as carbon monoxide between in use easily in less, have hidden danger such as anthracemia and gas explosion.

The utility model be a kind of water heater hot-water body and controller split design is provided at above-mentioned situation have new structure and a high split type gas heater of the thermal efficiency.

Gas heater of the present utility model is realized in the following manner: it includes hot water and controller two parts, and hot water links to each other with controller by pipeline; Described hot water is made up of underframe, the hot-water line of bringing delivery port into, burner and housing, and burner is positioned on the underframe, and housing is made up of inner cover, heat screen and outer cover; Inner cover and outer cover are tubular and are installed on the underframe; Insulating boot is a cup-shaped, tips upside down on the inner cover, and insulating boot is between inner cover and the outer cover and by the inner cover top braces and is connected; The junction of inner cover and insulating boot has the air-flow port, has air stream outlet around the top of outer cover, has the space between insulating boot and outer cover and the inner cover.

Gas heater of the present utility model has improved the structure of existing water heater hot-water body, adopts spiral helicine heating tube, and thermal efficiency height is easy to use; And because hot water and controller split design, can be installed in calandria outdoorly during installation, the pernicious gases such as carbon monoxide that the hot water combustion gas is produced can directly be emitted on outdoor, have eliminated the hidden danger of combustion gas poisoning; This water heater can generally replace existing multi-form gas heater.

Below in conjunction with accompanying drawing structure of the present utility model and technology contents thereof are further described:

Fig. 1 is a principle schematic of the present utility model;

Fig. 2 is the structural representation of hot water in the utility model.

Referring to Fig. 1 and Fig. 2, split type gas heater of the present utility model includes hot water 1 and controller 2 two parts, and hot water 1 links to each other with controller 2 by pipeline; Described hot water 1 is made up of underframe 11, the hot-water line 12 of bringing delivery port into, burner 13 and housing 14, and burner 13 is positioned on the underframe 11, and housing 14 is made up of inner cover 141, heat screen 142 and outer cover 143; Inner cover 141 and outer cover 143 are tubular and are installed on the underframe 11; Insulating boot 1412 is a cup-shaped, tips upside down on the inner cover 141, and insulating boot is between inner cover 141 and the outer cover 143 and by inner cover 141 top braces and is connected; Inner cover 141 has air-flow port 144 with the junction of insulating boot 142, has air stream outlet 145 around the top of outer cover 143, has space 146 between insulating boot 142 and outer cover 143 and the inner cover 141 and is used for the air communication mistake.The effect of above-mentioned inner cover is the recovery that improves heat, thereby improves the thermal efficiency; Insulating boot and outer cover adopt perfect heat-insulating material, reduce as far as possible so that heat scatters and disappears.

In order to guarantee that hot water is installed in the outdoor influence that is not subjected to external environment such as wind and rain etc., is equipped with a protective cover 147 at outer cover 143 tops.

Above-mentioned hot-water line 12 is interior outward corrugated tube; Hot-water line 12 is in hot water central authorities and is multi-layer helical around shape; Described multi-layer helical hot-water line is presented in wide narrow wide down around shape, to utilize the heat of gas flame fully, improves the thermal efficiency effectively.

Above-mentioned hot water shower nozzle adopts infrared burner.

Described controller mainly includes firepower control valve and discharge control valve; The firepower control valve can adopt existing general structures such as air valve, as the air valve on the existing gas heater etc., does not elaborate at this; Reach the purpose of control firepower size by the control gas flow, in order to guarantee opening and lighting a fire and carry out synchronously of control valve, link together by control valve and automatic starting impulse igniter, and straight-through burner igniting place, pulse igniter can adopt the existing general electric pulse ignitor that does not stop, in case igniting stops immediately, its mounting structure no longer elaborates at this for the technology that those skilled in the art know; Fuel gas inlet on the hot water links to each other by the outlet of Gas Pipe with the firepower control valve, and the import of firepower control valve connects gas source (as domestic gas jar etc.).The discharge control valve is used for controlling the discharge of hot water, according to circumstances can adopt two control valves, the cold water input control valve of instant heating water body and hot water hot water flow control valve, the cooling water inlet of hot water is by linking to each other with the outlet of cold water input control valve by water pipe, the import of cold water input control valve can directly link to each other with running water pipe, the hot water outlet of hot water links to each other by the import of hot-water line with the hot water flow control valve, the outlet of hot water flow control valve can directly connect the hot water use, as shower nozzle etc.Above-mentioned various valve all can adopt existing general valve mechanism, and they are installed on the control panel constitute water heater controller of the present utility model, for the sealing that guarantees controller and the security reliability when using, on controller, be that panel covers with a seal closure, on panel, be carved with various flow scales with the control valve opposite position, and have a pulse water indicator lamp and combustion gas water to refer to lamp etc., according to circumstances can be not in respect of modern times combustion fire, flame-out, missing of ignition verbal cue, the technology of relevant this respect sees also existing general electronic technology.

The utility model is installed in outdoor, its mounting structure can be installed on the wall by underframe, also can adopt similar existing installation of air conditioners version, this is not elaborated, pernicious gas is discharged effectively like this, can not produce and pollute, prevent from effectively to explode and hurt sb.'s feelings the home environment of resident family.
