Abstract

The utility model discloses a fuel-gas water heater with a built-in heating tube. The water heater includes a shell, a gas inlet, a heating tube, and a combustion chamber, etc. The heating tube is composed of a water inlet tube, a heated tube and a water outlet tube, the heated tube and the heat-absorbing sheets are arranged on upper end of the combustion chamber. The water heater is characterized in that the water inlet tube is attached on periphery of inner wall of the combustion chamber shell, rises spirally around inner wall of the combustion chamber shell, and then connects with the heated tube. A combustion cavity has a height of 5-8 cm. Since the water inlet tube of the utility model is arranged in the combustion chamber and attached on inner wall of the combustion chamber shell, the water inlet tube can fully absorb heat generated by fuel gas; height of the combustion cavity is reduced from 15 cm to 5-8 cm, so the heated tube may contact with flame head with highest temperature directly, thus the utility model has the advantages of capability to fully absorb heat generated by fuel gas, high heat efficiency, rapid water temperature rising, good energy saving effect, and large adjustable range of water temperature. The utility model is applicable to fuel-gas water heater of various types.

Description

The gas heater that heating tube is built-in

Technical field

The utility model relates to water heater, especially relates to the built-in gas heater of a kind of heating tube.

Background technology

Gas heater is higher with its thermal efficiency, water heats up very fast, cold and hot adjustable, convenient and practical advantage, huge numbers of families have been entered apace, bring great convenience for people's life, but because the heating tube of existing gas heater has only heat pipe part and heat absorbing sheet to be arranged in the combustion chamber, play then outer being attached on the outer wall of burning chamber shell of water inlet pipe of pre-heat effect, water inlet pipe just is difficult to fully directly absorb the heat that combustion gas produces like this, prolonged the heating-up time, and the bottom row's heat pipe in combustion chamber from the distance of duration and degree of heating be the height of combustion chamber up to 15cm about, distance is too big, it is reasonable inadequately to design, make heat pipe can't touch the maximum temperature that duration and degree of heating produces, heat can't fully be absorbed, heat has been wasted in vain, thereby existing gas heater exists, and to expend combustion gas many, oxygen demand is big, the shortcoming that waste gas is many.

Summary of the invention

The purpose of this utility model is to provide a kind of can fully absorb the gas heater that heat, the thermal efficiency are higher, the water intensification is faster, energy-saving effect better heating pipe is built-in that combustion gas produces.

The purpose of this utility model is achieved in that the utility model comprises shell, air inlet pipe, heating tube, duration and degree of heating, combustion chamber, heat absorbing sheet and igniter, heating tube is made up of water inlet pipe, heat pipe and outlet pipe, heat pipe and heat absorbing sheet are placed on the upper end in the combustion chamber, feature is to be attached in the water inlet pipe around the inwall of burning chamber shell, and, be connected with heat pipe again around the rising of burning chamber shell spiral inner wall.

The height of combustion chamber is 5-8cm.

The utility model is owing to water inlet pipe being built in the combustion chamber and being attached on the burning chamber shell inwall, and around the rising of spiraling of burning chamber shell inwall, the water inlet pipe that plays pre-heat effect can fully absorb the heat that combustion gas produces, be difficult to fully directly to absorb the shortcoming that heat that combustion gas produces has prolonged the heating-up time thereby the water inlet pipe that has overcome existing gas heater is placed on that the combustion chamber causes, and the height of combustion chamber drops to 5-8cm about by original 15cm, so just make heat pipe can directly touch the maximum temperature that duration and degree of heating produces, heat just can fully be absorbed, thereby the thermal efficiency is improved greatly, and energy-saving effect is highly significant also; Intake valve adopts stop valve to regulate air inflow, thereby realizes the air inflow step-less adjustment.Therefore the utlity model has the advantage that heat, the thermal efficiency that can fully absorb the combustion gas generation are higher, the water intensification is faster, energy-saving effect better, the water temperature adjustable range is big, be applicable to the gas heater of existing various models.

The specific embodiment

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

The utility model comprises shell 1, heat absorbing sheet 2, air inlet pipe 6, heating tube 7, combustion chamber 8, duration and degree of heating 11 and igniter, heating tube 7 is made up of water inlet pipe 5, heat pipe 3 and outlet pipe 9, heat absorbing sheet 2 and heat pipe 3 are placed on the upper end in the combustion chamber 8, be attached in the water inlet pipe 5 around the inwall of burning chamber shell 4, and, be connected with heat pipe 3 again around the rising of burning chamber shell 4 spiral inner walls.

The height h of combustion chamber 10 is 5-8cm.Intake valve adopts stop valve to regulate air inflow, thereby realizes the air inflow step-less adjustment.
