Abstract

The utility model provides a multifunctional cooking and heating furnace, which comprises a hearth, an inner water cover, an outer water cover, a fire return opening, a ring flue and a chimney; the hearth is surrounded by the inner water cover, the outer water cover covers the inner water cover stably; the ring flue is communicated with the chimney between the inner water cover and the outer water cover. The furnace is characterized in that: the fire return opening is arranged towards the chimney and respectively connected with the hearth and the ring flue. That the fire return opening communicated with the ring flue is arranged towards to the chimney enables furnace fire full entry into the ring flue, rather than directly discharging from the chimney, full use of the furnace fire and high heat efficiency.

Description

Multifunctional cooking and warming stove

The utility model provides a kind of multifunctional cooking and warming stove, especially relates to a kind of multifunctional water radiator of fire coal.

At present, the hot-water heating stove that adopts inside and outside water jacket and inside and outside water jacket to form annular flue has a lot, with regard to its technical scheme, mostly be in order fully to improve the thermal efficiency, around fire door, be provided with and return burner, through returning the stove fire that burner enters annular flue, its heat is discharged through chimney after fully being absorbed by the water in the inside and outside water jacket again.Defective is: since fire door around be to return burner, stove fire is just directly got shortcut and is entered chimney and drained from returning burner, its heat can't fully be absorbed by the water in the inside and outside water jacket, the stove fire utilization rate is low, the thermal efficiency needs further improvement.

The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, the stove fire utilization is abundant, the thermal efficiency is high multifunctional cooking and warming stove.

The purpose of this utility model is achieved in that

Comprise burner hearth, inner water sleeve, outer water jacket, return burner, annular flue and chimney, wherein burner hearth is surrounded by inner water sleeve, outer water jacket fixed cover is on inner water sleeve, be that annular flue is communicated with chimney between the inside and outside water jacket, it is characterized in that: return the opposite that burner is arranged on chimney, be communicated with stockhole and annular flue respectively.

Described multifunctional cooking and warming stove is provided with fire-sealing ring around the fire door, is set with the plate washer sealing below the part of fire-sealing ring to return burner.

The utility model compared with prior art, what be communicated with annular flue returns the opposite that burner only is arranged on chimney, make stove fire all enter annular flue like this, after its heat is fully absorbed by the water in the inside and outside water jacket, discharge through chimney again, rather than get shortcut and directly discharge from chimney, the stove fire utilization is abundant, thermal efficiency height;

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of fire-sealing ring embodiment illustrated in fig. 1;

Among the figure: 1, burner hearth 2, inner water sleeve 3, outer water jacket 4, return burner 5, annular flue 6, chimney 7, stockhole 8, fire door 9, fire-sealing ring 10, plate washer 11, ash bucket

Below in conjunction with accompanying drawing the utility model is described further:

Burner hearth 1 is surrounded by inner water sleeve 2, the bottom of burner hearth 1 is an ash bucket 11, outer water jacket 3 fixed covers are on inner water sleeve 2, be that annular flue 5 is communicated with chimney 6 between the inside and outside water jacket, returning the opposite that burner 4 is arranged on chimney 6 is communicated with stockhole 7 and annular flue 5 respectively, fire-sealing ring 9 is shelved on the fire door 8, is set with plate washer 10 below the part fire-sealing ring 9 and is used to seal, change the size of returning burner 4.Owing to return the opposite that burner 4 is arranged on chimney 6, so just prevented that stove fire from getting shortcut and enter chimney 6 and drain from returning burner 4, but all entered annular flue 5, after its heat is fully absorbed by the water in the inside and outside water jacket, discharge through chimney 6 again, energy-conservation, thermal efficiency height.

Claims (2)

1, a kind of multifunctional cooking and warming stove, comprise burner hearth (1), inner water sleeve (2), outer water jacket (3), return burner (4), annular flue (5) and chimney (6), wherein burner hearth (1) is surrounded by inner water sleeve (2), outer water jacket (3) fixed cover is on inner water sleeve (2), be that annular flue (5) is communicated with chimney (6) between the inside and outside water jacket, it is characterized in that: return the opposite that burner (4) is arranged on chimney (6), be communicated with stockhole (7) and annular flue (5) respectively.

2, multifunctional cooking and warming stove as claimed in claim 1 is characterized in that: be provided with fire-sealing ring (9) around the fire door (8), be set with plate washer (10) sealing below the part fire-sealing ring (9) to return burner (4).
