Abstract

The utility model relates to a high efficiency gas water heater, in particular to a gas water heater whose body has an airproof gas entering space. A lower controlling space is provided with relative controlling components. Inside of the body is provided with a heat collector and a burning room which contains a burner. The heat collector and the burning room cooperate with an inner shell body and an exhausting inner cap so as to form an exhausting space and make the other gas spaces of the body to be gas entering spaces, so as to make a gas entering pipe which is communicated with the gas entering space can input the air to the gas to mix and burn, to discharge the exhaust gas after burning from an exhaust fan and the gas exhausting pipe. Besides, the heat preserving burning room can elevate the heat efficiency by more than 30 percent so as to save heat.

Description

The high thermal efficiency gas water heater

The relevant a kind of high thermal efficiency gas water heater of the utility model.

Gas water heater is obtained the main source of hot water for the modern, but can mix a large amount of fresh airs during gas-fired, and discharges large quantity of exhaust gas.General gas water heater adopts open combustion chamber, sucks the direct and surrounding air convection current of air and combustion gas when making gas-fired, the necessary condition when therefore good ventilated environment becomes this type of gas water heater use.But the space is narrow and small in the city now, and the installation place of this type of gas water heater there is no sufficient airspace in some cases, add the Heaven when cold door and window close, often leak or incomplete combustion causes the injures and deaths incident of anthracemia because of coal gas.

The purpose of this utility model is promptly providing a kind of high thermal efficiency gas water heater, and this water heater can suck the outdoor air convection current, and in coal gas mixed combustion after waste gas is discharged outdoor, and can be installed in indoor safely.

For achieving the above object, water heater main body of the present utility model can form an airtight air chamber space, and another control of its below is inserted related elements such as controller, igniter, magnetic valve in space, and other is positioned in this control space a jet for gas, and towards the combustion chamber of body interior; The combustion chamber of an inner predeterminable heat collector of aforementioned body and a structure combination burning device, these heat collectors and combustion chamber can cooperate that cap spare forms an airtight exhaust space in the exhaust with inner housing; And make other air chamber space of main body become admission space: an air inlet pipe can communicate with above-mentioned admission space, one escape pipe then can be located at tracheae inside, thereby extraneous air can be introduced and coal gas mixed combustion by air inlet pipe, and be made waste gas after burning force to discharge by escape pipe; Thereby whole mechanism Combination Design is rationally perfect, makes its combustion process not use room air, and the safety in utilization can improve its indoor installation the time, and the thermal-insulating type combustion chamber can improve the thermal efficiency more than 30%, saves heat energy.

Below conjunction with figs. be elaborated to the utility model embodiment and further specify characteristics of the present utility model and advantage; Wherein

Fig. 1 is the utility model preferred embodiment structure chart;

Fig. 2 is that upper semisection embodiment illustrated in fig. 1 is connected the view on metope; And

Fig. 3 is the schematic diagram of duty embodiment illustrated in fig. 1.

At first see also Fig. 1, the utility model water heater main body 10 can form a closed air chamber space 11 basically, thereunder then can control space 20 with another and connect a water inlet pipe 21, an outlet pipe 22 and a gas pipe 23 respectively; This space and predeterminable controller 24, igniter 25, first magnetic valve 26 and second magnetic valve 27 then can be provided with a water flow switch 28 on the above-mentioned water inlet pipe 21.29 at one jet for gas is installed on the closed bottom 12 of main body 1, and makes its combustion chamber towards main body 10 inside.

Aforementioned body 10 inner predeterminable heat collectors 30 and include the combustion chamber 40 of burner 50.These heat collectors 30, combustion chamber 40 can cooperate cap spare 62 in the exhaust with inner housing 61 with its internal-combustion device 50, and form an airtight exhaust space 60, thereby make other body interior air chamber space beyond this exhaust space 60 become admission space.The conduit 51 of said burner 50 bottom surfaces passes the closed bottom 67 of inner housing 61, and to aim at jet for gas 29, giving gas sprays into and introduce air.

Above-mentioned heat collector 30 can be every establishing a plurality of heat absorbing sheets 32 on circuitous coil pipe 31, and these circuitous coil pipe 31 1 ends connect water inlet pipe 21, and the other end then is connected to outlet pipe 22.Simultaneously, can wrap in 40 interior week in the combustion chamber and establish Nai Gaore insulation material 41 to promote the thermal efficiency more than 30%.

In illustrated preferred embodiment, cap spare 62 is installed in heat collector 30 tops in the exhaust, and side folding is set as the inclined-plane that upwards dwindles, and end then forms another little space 63 with continuous flanging in addition, supply to insert an exhaust blower 64, and a contiguous blast switch 65.Its top predeterminable one is positioned at the path adapter 66 of air inlet pipe 71 inside, big footpath simultaneously, for socket one escape pipe 71.Above-mentioned air inlet pipe 70 then energy is connected in the above-mentioned admission space with another adapter 72.

As shown in Figure 2, above-mentioned air inlet pipe 70 can be bent jointly together with the escape pipe 71 of its inside and is connected to a metope 73, with exhaust by the indoor guide chamber outside.

Now see also Fig. 1,3, according to the water heater of said structure after the user opens current, water flow switch 28 induction of promptly intaking, and via controller 24 makes exhaust blower 64 startings, controller 24 is then controlled female stove mouth 42 again and is lighted, and by the female fire gas of first magnetic valve, 26 supplies, makes female fire burns, inductive rod 43 then after induction via controller 24 make the main fire gas of second magnetic valve 27 supply, open main fire and form balance mode burning heating.In this heating flame process, outdoor air is sent in the admission space 11 of main body by air inlet pipe 70, further flow in the conduit 51 of burner 50, burn, take over 66 and outdoor by exhaust space 60 through path then by escape pipe 71 discharges and mixes with coal gas.This cyclic process makes waste gas and has the unlikely inflow of poisonous gas indoor, and needn't use room air, is particularly suitable for being installed in indoor use.

Large quantity of exhaust gas when the utility model high thermal efficiency gas water heater can burn coal gas with water heater is forced to discharge, and prevent that effectively coal gas from leaking or the caused carbon monoxide poisoning event of incomplete combustion, whole mechanism Combination Design is rationally perfect simultaneously, and heat preserving type combustion chamber and balanced type burner can more effective control water temperatures.
