Abstract

The utility model discloses an energy-saving kettle for heating water, which is composed of a handle 1, a kettle lid 2, a kettle body 4, a reheater 5, an inner concave kettle bottom 6, and a fume exhaust pipe 7. When the utility model is used, an air gap is not reserved between the circumference of the kettle bottom 6 and the plane surface of a cooker; a flame can carry out the combustion and the heating of the inner concave space of the kettle bottom 6, the heat radiation is partitioned, and the heat convection can be eliminated; fume gas and partial flames can be led into the reheater 5 from a fire inlet hole 8 and can be exhausted from the fume exhaust pipe after reheating water. The heat of the fume gas and the flame can be utilized more, the heat loss can be reduced, and the heat efficiency can be increased.

Description

A kind of energy saving water boiling kettle

The utility model belongs to a kind of life appliance.

Before the utility model is made, do not see the report and the use of similar kettle as yet.

For a long time, the boiled water pipe that people habitually practise is platybasic type, this kettle is in heating up water, leave certain space at the bottom of the kettle and between the kitchen range, so that flame burns at the bottom of kettle preferably, the flue gas of burning discharges around at the bottom of the kettle, and inevitable like this some heat is arranged to the space and loss in vain by heat radiation and fume afterheat, thereby has reduced the thermal efficiency and energy utilization rate.

The purpose of this utility model provides a kind of minimizing thermal losses, improves the kettle of the thermal efficiency and energy utilization rate.

The purpose of this utility model is to be realized by following technical proposals: this energy saving water boiling kettle is by the kettle body, pot lid, handgrip, Hu Zui, form at the bottom of the kettle, the middle part is inwardly recessed at the bottom of the said kettle, form the burning heating space, the diameter of recess accounts for 3/4ths to 6/7ths of the straight end at the bottom of the kettle, the recessed degree of depth can normal combustion be advisable with flame, advance fire hole at the uniform 1-8 in the appropriate location of recess, this energy saving water boiling kettle also has an after-heater that is arranged in the kettle, after-heater is made by vacant duct in the T font, the heater bottom is connected with the fire hole that advances at the bottom of the kettle, after-heater one end is as the slightly upward pass-out kettle of smoke exhaust pipe body, and perhaps connect a smoke exhaust pipe in the after-heater appropriate location slightly upward to pass-out kettle body.

Adopt the technical program, compare with original technology, have the following advantages: the one, reduced thermal losses, because the kettle bottom perimeter directly is placed on the kitchen range plane when using, fuel is indent space combustion at the bottom of kettle only, cut off heat radiation, eliminated thermal convection current, thereby reduced the thermal losses that causes because of heat radiation and thermal convection current; The 2nd, flame is after concave space heats for the first time to Hu Shui at the bottom of the kettle, combustion product gases and a small amount of flame are introduced after-heater from advancing fire hole, fume afterheat and a small amount of flame carry out the heating second time to water, can more utilize the heat energy and the fume afterheat of burning, reduce the heat that flue gas is discharged, so have the thermal efficiency and the high advantage of energy utilization rate.

Further the utility model is made detailed description below in conjunction with drawings and Examples;

Fig. 1 is the structural representation of the utility model energy saving water boiling kettle.

In the embodiment in figure 1, at the bottom of the handgrip 1 of energy saving water boiling kettle, pot lid 2, kettle body 3, kettle mouth 4, the kettle 6, after-heater 5 and smoke exhaust pipe 7 are made by aluminum material; At the bottom of the kettle 6 recess diameters be at the bottom of the kettle diameter 4/5ths, the recessed degree of depth is 5-10cm; On 6 recessed circumferential edge at the bottom of the kettle 2 diameters of cloth be 3-6cm advance fire hole 8; After-heater adopts vacant duct in the T font, and caliber is with to advance fire hole 8 identical, and with advance fire hole 8 and be tightly connected; Smoke exhaust pipe 7 diameters are 3-5cm, the port of export deflection 4-7cm that makes progress, and smoke exhaust pipe 7 is made one with after-heater 5, and the port of export seals with water-impervious with kettle body 3.The kettle that adopts technique scheme to make, under identical water temperature condition with identical burning with class A fuel A, the time that water flask boils, save 30-50% than common kettle, can improve thermal efficiency 30-50%, reach energy-conservation purpose.

Vacant duct structure in the round pie structure of sky or the elbow-shaped can also adopt vacant duct structure in cross or the spirality in post bake 5 also can adopt, and can both obtain desirable effect.
