Abstract

The utility model discloses a gas stove hearth capable of recovering heat energy; a hearth body is externally provided with an external wind baffle ring; the part of an opening of the hearth is provided with a plurality of guide exhaust holes, and hot fume generated by combustion enters into a channel formed by the external wind baffle ring and the hearth body through the guide exhaust holes; a coil pipe is arranged at one side of the external wind baffle ring towards the interior of the channel; the coil pipe is provided with a heat absorption fin; and the coil pipe and the heat absorption fin are used for absorbing the heat of the hot fume entering into the channel, and heating the circulating water in the coil pipe. A heat insulating layer is arranged outside the external wind baffle ring, so that the heat of the hot fume can be absorbed in the channel. After the heat of the fume is absorbed by the channel, the fume is discharged into the specific location along a chimney flue. The heated circulating water can be connected with a kitchen hot water system so as to be used as hot water for production and life of a kitchen, or can be connected with a kitchen water carrying fume hood system so as to absorb the oil and fume by the hot water and ensure the oil and fume discharge of the kitchen to be more environment-friendly.

Description

Can reclaim the gas-cooker burner hearth of heat energy

Technical field

The utility model relates to a kind of gas-cooker burner hearth, relates to a kind of gas-cooker burner hearth that can reclaim heat especially.

Prior art

The general gas kitchen range burner hearth that generally uses is open at present, the heat that burning produces is except that a part of heating object bulk absorption, remaining heat all directly is transmitted to the ambient air from burner hearth, like this with regard to loss a lot of heat energy, and the temperature in the kitchen is significantly risen, brought arduous working environment for the kitchen staff.

Summary of the invention

The purpose of this utility model is to have overcome deficiency of the prior art, and a kind of gas-cooker burner hearth that can reclaim heat energy is provided.In order to realize this purpose, mainly taked following technical scheme:

The burner hearth body is provided with an outer wind loop outward, at the burner hearth oral area some directing exhaust gas hole is set, hot flue gas wind loop and the formed passage of burner hearth body outside the directing exhaust gas hole enters that burning is produced.And on the side of wind loop in this passage coil pipe is arranged outside, and the heat absorption fin is housed on the coil pipe, coil pipe and heat absorption fin absorb the heat of the hot flue gas of admission passage and the recirculated water in the heat(ing) coil.For the heat that makes hot flue gas is absorbed in passage, wind loop is provided with thermal insulation layer outward outside.The flue gas that has been absorbed heat through passage is discharged into assigned address along flue.

Heated recirculated water can insert the kitchen hot-water heating system, supplies with the kitchen and produces with hot water and domestic hot-water.Also can insert kitchen hydro-vent system, utilize hot water absorption oil smoke, make the oil smoke discharge environmental protection more in kitchen.

Description of drawings

Fig. 1 is a structure chart of the present utility model.

Wherein, 1-burner hearth body, the outer wind loop of 2-, 3-coil pipe, 4-heat absorption fin, 5-thermal insulation layer, 6-burner, 7-flue.

In addition, A is a steam vent, and B is the recirculated water inlet, and C is a circulating water outlet.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

Gas-cooker burner hearth described in the utility model is by burner hearth body 1, outer wind loop 2, coil pipe 3, heat absorption fin 4, thermal insulation layer 5, burner 6, flue 7, steam vent A, and recirculated water inlet B and outlet C form.The hot flue gas of discharging that is produced by burner (6) burning through several directing exhaust gas holes of burner hearth body 1 oral area A introduce by burner hearth body 1 and outside the passage formed of wind loop 2, on the side of wind loop 2 in this passage coil pipe 3 is arranged outside, heat absorption fin 4 is housed on the coil pipe 3, flow through the heat of discharging flue gas of the passage that burner hearth body 1 and outer wind loop 2 formed in passage by 4 absorptions of the heat absorption fin on coil pipe 3 and the coil pipe, be connected with recirculated water in the coil pipe, recirculated water after will absorbing heat by water pump is delivered to water tank through coil pipe 3 recirculated water delivery ports, again the water of water tank is introduced coil pipe 3 recirculated water water inlets.Water tank inserts the kitchen hot-water heating system, supplying with the kitchen produces with hot water and life hot water, perhaps water tank inserts kitchen hydro-vent system, utilize hot water absorption oil smoke, make the oil smoke discharge environmental protection more in kitchen, the discharging flue gas of the passage that burner hearth body 1 and outer wind loop 2 formed of flowing through is fully absorbed heat after exhaust uptake 7 is disposed to assigned address by the heat absorption fin on coil pipe 3 and the coil pipe 4 in by passage, and outer wind loop 2 outsides are provided with thermal insulation layer 5.

This device heat recovery efficiency height is making full use of on the basis of heat energy, has reduced the noise of kitchen range, and the thermal efficiency in the burner hearth also is improved simultaneously.The recuperation of heat that the next gas burner of normal condition per hour uses can produce the hot water (more than 60 degree) greater than 0.5 ton, has reduced the temperature in kitchen simultaneously, has reduced the discharging of heat in the waste gas, protects the environment to benefit the people.

Claims

1. gas-cooker burner hearth that can reclaim heat energy, it is by burner hearth body, outer wind loop, coil pipe, heat absorption fin, thermal insulation layer, burner, flue, steam vent, recirculated water inlet and circulating water outlet are formed; It is characterized in that: the burner hearth body is provided with steam vent, described steam vent will be guided to by the hot flue gas that the burner burning produces in the passage of being made up of burner hearth body and outer wind loop, the side of outer wind loop in passage is equipped with coil pipe, the heat absorption wing is housed on the coil pipe, recirculated water is arranged in the coil pipe, thereby coil pipe and heat absorption wing absorb the recirculated water in the heat heat(ing) coil of hot flue gas, discharge along flue through the flue gas of endothermic process, and wind loop is provided with thermal insulation layer outward outside.

2. the described gas-cooker burner hearth that can reclaim heat energy of claim 1 is characterized in that described recirculated water inlet and circulating water outlet link to each other with water tank for kitchen use.
