Abstract

The utility model provides a high-efficiency water heater utilizing waste heat, making full use of the radiant heat, the conductive heat and the convective heat produced by the burning gas. The utility model is characterized in that the inner wall of the combustion chamber is in a parabolic shape with a silver light reflecting surface to make the burning flame on the focus of the parabola. The outside of the combustion chamber is provided with a circular water chamber, and a heat radiator is installed in the water chamber to make the convective heat brought by the smoke transferred to the water to improve the waste heat utilization rate of gas.

Description

Water heater utilizing waste heat of gas stove

The invention relates to a kind of invention of gas range residue heat water heater.Liquefied petroleum gas stove when burning under the best circumstances the thermal efficiency have only about 55%, and use in the ordinary course of things, the thermal efficiency will also be significantly less than this standard.Therefore say gas range in use, will also have a large amount of waste heats to utilize.More existing gas range water heaters obtain sufficient quantity oxygen when making gas-fired and waste gas are discharged smoothly.Leave certain clearance between water heater and the cooker (that is: pot etc.), a large amount of waste heats scatters and disappears by convection current, therefore, a part of radiant heat that existing residue heat water heater has been produced when only having utilized gas-fired and conduct hotly, thereby the utilization rate of heat energy is not high.The purpose of this invention is to provide a kind of radiant heat that is produced when utilizing gas-fired more fully and conduction heat, also utilized the efficient residue heat water heater of advection heat fully.

Fig. 1 is the front view of residue heat water heater.

Fig. 2 is the vertical view of residue heat water heater.

Fig. 3 is the A-A profile in the vertical view of residue heat water heater.

Fig. 4 is the B-B profile in the front view of residue heat water heater.

Referring to Fig. 1 as can be seen, residue heat water heater mainly can be made up of lower part.Clean-burning combustion chamber 8 and upper wall 15, sidewall 13 and the lower wall 12 common circular water cavities of forming can give gas.Combustion chamber 8 inwalls are made into parabola shapedly, and the flame that produces when making gas-fired 9 burnings is on parabolic focus, and combustion chamber 8 usefulness aluminium alloys or galvanized steel plain sheet are made, and have the argenteous light face that returns.By the parabola optical property as can be known, the radiant heat that is produced in combustion chamber 8 can return in large quantities and be mapped to the bottom of a pan and get on, and heat energy is utilized fully.Obtain sufficient oxygen when making gas-fired, between combustion chamber 8 and gas-fired 9, leave certain clearance, and make 8 bottoms, combustion chamber have one section arc flange, not only help air and enter combustion chamber 8 smoothly, but also stoped dissipation of heat energy.On water heater top stove circle 1 is housed also, stove circle 1 has a crimp, can ride on the water heater, stove circle 1 is up big and down small circular cone bench-type, φ a size can change according to the size in the bottom of a pan, make the bottom of a pan apart from gas-fired 9 a maintenance optimum distance, stove circle 1 can be made into the bore specification that varies in size according to instructions for use, the middle exchange easy to use.A large amount of waste heats that waste gas discharges and utilize fully waste gas to take away smoothly when burning in order to make.A plurality of ventilation radiating tubes 16 are housed in water cavity, and ventilation radiating tube 16 is connected with the air admission hole 17 on 8 tops, combustion chamber and the steam vent 14 on the water cavity sidewall 13, and is welded with several fin 10 on ventilation radiating tube 16, and heat is transmitted in the water rapidly.

As can be seen from Figure 1 and Figure 4, water cavity lower wall 12 upper punches have strengthening groove 11 and strengthen nest 7, and water can flow to along strengthening groove 11 smoothly to be strengthened in the nest 7.Tap 4 also is housed on water cavity sidewall 13, and links to each other with bend pipe 6.Bend pipe 6 puts in to be strengthened having one section rubber tube 5 on the tap 4 in the nest 7, and its length should surpass strengthens 2-3 centimetre of the nest degree of depth, utilizes siphon principle, the water in the water cavity all can be drained.

From Fig. 2 and Fig. 3, it can also be seen that, on water cavity sidewall 13, have flame-observing hole 18, and sight fire tube 19 is housed, so that observe the combustion case of flame in the combustion chamber 8, and the size of regulating flame as required.Being equipped with on water cavity upper wall 15 pours water covers 3 and have water filling port 2, with the usefulness of pouring water.Irrigation pipe 21 also is housed and is connected with the rubber tube 22 of pouring water.Rubber tube 22 links to each other with water tap, can easily running water be irritated in the intake antrum.Water level display 20 also is housed on water cavity upper wall 15, utilizes law of buoyancy can watch the height of water level in the water cavity.

The use of this residue heat water heater will improve the utilization rate of waste heat of coal gas greatly, reaches the purpose of energy savings.The use of this residue heat water heater will bring benefit to each family, can obtain a large amount of hot water after cooking, and gives to do the wash to bring great convenience.
