Described tubular type heat radiating structure comprises water pipe and is located at the heating element heater in the water pipe outside; Described water pipe is aluminum pipe; The top port of described water pipe is higher than the water storage cavity water level; Also be communicated with a heat radiating structure intake antrum between the bottom port of described water pipe and the water injection pipe.
Described water flowing out structure comprises water chamber and is located at steam hole, outlet pipe on the water chamber; Also be provided with the steam isolating construction in the described water chamber.
Compared with prior art, the beneficial effects of the utility model are,
The utility model can accurately be controlled the water yield that enters the tubular type heat radiating structure by water inlet structure and level control structure for water are set, and reaches good heating effect, and that has improved water flowing out structure goes out the hot water effect.
Description of drawings
Fig. 1 is the structural representation of the Instant heating type kettle of the utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
As shown in Figure 1, the utility model discloses a kind of Instant heating type kettle, comprise water-supply structure 1, water inlet structure 2, return-flow structure 7, tubular type heat radiating structure 3 and water flowing out structure 5, water inlet structure 2 comprises water pump 21, water inlet pipe 22, water injection pipe 23 and water storage cavity 24, one end of water inlet pipe 22 is communicated with water storage cavity 24, the other end connects the water side of water pump 21, the water intake end of water pump 21 is connected with water-supply structure 1, one end of water injection pipe 23 is communicated with water storage cavity 24, the other end is connected to water flowing out structure 5 by tubular type heat radiating structure 3, return-flow structure 7 one ends are communicated with water storage cavity 24, the other end connects the water intake end of water pump 21, and described return-flow structure 7 is used for receiving the water that surpasses water storage cavity 24 1 predetermined water level.
Water-supply structure 1 provides the water source to water inlet structure 2, under the effect of water pump 21, water inlet pipe 22 is delivered to the water source in the water storage cavity 24, and by water injection pipe 23 with water extraction for to tubular type heat radiating structure 3,3 pairs of water of tubular type heat radiating structure heat, realize out hot water in the current Inlet and outlet water structure 5 after the heating, the water that return-flow structure 7 will exceed predetermined water level is back to the water intake end of water pump 21, thereby utilizes the water balance of water inlet structure and water-supply structure to control water level in the water storage cavity.
Particularly, described return-flow structure 7 is an overflow pipe, and the port that overflow pipe is communicated with water storage cavity 24 is higher than the port that water injection pipe 23 is communicated with water storage cavity 24.
Particularly, described water-supply structure 1 comprises water tank 11 and is located at the Cistern valve 12 of water tank 11 lower part outlets, and Cistern valve 12 is communicated with water pump 21 by water supply line 13.Described water supply line 13 also is provided with a valve 14 with the interface of water tank 11, is used for when water tank 11 places on the water supply line 13, and valve 14 is opened, and when water tank 11 was removed water supply line 13, valve 14 was closed the water that stops in the water supply line 13 and outwards flowed out.
Described tubular type heat radiating structure 3 comprises water pipe 31 and is located at the heating element heater 32 in water pipe 31 outsides, described water pipe 31 is aluminum pipe, the top port of described water pipe 31 is higher than water storage cavity 24 predetermined water level, also is communicated with a heat radiating structure intake antrum 33 between the bottom port of described water pipe 31 and the water injection pipe 23.In the utility model, under the control of return-flow structure 7, can guarantee effectively that the height of aspect ratio water storage cavity 24 water levels of top port of described water pipe 31 is high, be flowed out in the water flowing out structure 5 by tubular type heat radiating structure 3 delivery ports so that hot water can boil to boiling.
