Abstract

The utility model relates to a fast heating kettle, which is mainly composed of a casing, a heat exchanger and a flame pipe group. The heat exchanger thereof, which is composed of a heat-exchanging water pipe group and a heat-absorbing piece group, is sheathed in a casing of a heat absorber; the flame pipe group is composed of a middle flame pipe and a valve flame pipe; heat is exchanged with water through heat-exchanging water pipes, the middle flame pipe and the outer wall of the valve flame pipe. The utility model, which has the advantages of high thermal efficiency, quick temperature rise and convenient use, can provide boiling water and shower water.

Description

Fast heating kettle

The utility model belongs to a kind of cooking stove rapid hot water utensil.

Along with The development in society and economy, people's living condition is constantly improved, and urban family uses hot water and boiling water just progressively to move towards electrified and combustion gas automation.But the actual state that is limited to present China, because most of regional power shortages and combustion gas and Gas appliance cost an arm and a leg, China belongs to world coal production consumption big country in addition, make greatly middle and low income family can not take leave of still that traditional cooking stove is to boil water, the history of bathtub hip bath, the modernization of this and economic society is very disproportionate.

The purpose of this utility model is the actual state at current China, designs a kind ofly can extensively be adapted to boiling water being provided fast and supplying with hot water automatically of the kitchen ranges of cooking a meal such as various coal kitchen ranges, gas-cooker and oil oven energy-and time-economizing, the convenient Fast heating kettle that adapts to.

Major technique measure of the present utility model is as follows:

A kind of Fast heating kettle, has housing, establish water inlet pipe and outlet pipe on the housing, the fire tube group is established on top, central area in housing, and heat exchanger is established in the bottom, and its heat exchanger is made up of heat exchanging water pipe's group and heat absorbing sheet group, the outer cover outer cover of heat exchanger, it is uprightly plate shaped that heat absorbing sheet in the heat absorbing sheet group all is, and has the hole that stretches through for the heat exchanging water pipe on it, and heat exchanging water pipe's two ends all communicate with the storage area of enclosure interior; The fire tube group is made up of middle fire tube and lobe fire tube, and fire tube group top is established fire tube and put on the shelf, and the fire tube base is established in the bottom.

The utility model is owing to take by direct heat transfer among the heat exchanging water pipe of water in heat exchanger, and heat exchanging water pipe and heat absorbing sheet directly are subjected to fire grilled, thereby heat exchange area is big, heat energy utilization rate height, and the waste heat in middle fire tube and lobe fire tube again can be by the water heat-shift in fire tube wall and the storage area, and the heat energy utilization rate is higher, by send constantly into cold water in kettle, can export hot water continuously for shower usefulness, thereby reach the purpose of this utility model.

Below in conjunction with accompanying drawing and the embodiment that provides the utility model is further described.

Fig. 1 is the Fast heating kettle structural representation;

Fig. 2 is a water temperature control valve structural representation;

Fig. 3 is a water temperature control valve schematic appearance;

Fig. 4 is the fire tube cross sectional representation;

Fig. 5 is the heat exchanger stereogram.

See also shown in Figure 1ly, this Fast heating kettle mainly is made up of housing, heat exchanger and fire tube group.Wherein:

Housing is made up of shell body 9, inner housing 7 and middle heat-insulation layer 8, establishes water inlet pipe 11 and outlet pipe 12 at the top of housing, and water inlet pipe 11 is inserted to bottom side in the housing; Establish boiling water outlet 10 on the housing wall, establish a valve in this boiling water outlet 10, case top is established a handle 13, also establishes safety valve 15 and thermometer 16 at the end face of housing.

Heat exchanger: by the heat exchanging water pipe organize 3 and heat absorbing sheet group 2 form, be enclosed within the outer cover of heat exchanger 1, it is uprightly plate shaped that the heat absorbing sheet in the heat absorbing sheet group 2 all is, and has the hole that stretches through for the heat exchanging water pipe on it, as shown in Figure 5.Heat exchanging water pipe's two ends all communicate with the storage area of enclosure interior.

The fire tube group: be made up of middle fire tube 5 and the lobe fire tube 6 that is enclosed in middle fire tube 5 peripheries, fire tube support 14 is established at fire tube group top, and fire tube base 4 is established in the bottom.For increasing heat exchange area, the cross section of middle fire tube 5 and each lobe fire tube 6 all is designed to ω shape, as shown in Figure 4.And each fire tube is axially all made up-small and down-big taper, is subjected to resistance after hot gas enters like this, and pressure raises thereby flow velocity reduces, and has accelerated the programming rate of heat-absorbent surface; When hot gas flows out from the osculum end of Taper Pipe, present jet phenomenon, thereby strengthened the suction force in the cooking stove, make that oxygen supply increases in the burner hearth, the intensity of a fire is more prosperous.

The utility model also is furnished with a special-purpose heat control valve 17, shown in Fig. 2 and 3, it is made up of valve body 172 and spool 173, establish 4 intake-outlet A, B, E, F on this valve, wherein A is a cooling water inlet, and B is that the water inlet pipe 11 on cooling water outlet and the housing joins, and E is that the outlet pipe 12 on hot water inlet and the housing joins, F is a hot water outlet, and establishes a regulating spool 173 and distribute the regulating handle 171 of cool water quantity with regulating pondage and water temperature to adjust to B and F two delivery ports on heat control valve.

After tested, manufacture a diameter 220mm, high 320mm, capacity is 9.5 liters a Fast heating kettle, is placed on when using on the common honeycomb briquette kitchen range, and its firing rate can reach 43 ℃/minL, is 48.36 ℃/minL on liquefied gas cooker, and the thermal efficiency is up to 93%.
