Embodiment
As shown in Figure 1, first embodiment of the present utility model, a kind of solar water heater hot water supercharging drain pump, comprise water pump, have water intake 1-1 and water outlet 1-2 on the pump housing 1 of water pump, the described pump housing 1 is provided with installing stopper 2, described water intake 1-1 is positioned at installing stopper 2 or is positioned on the installing stopper 2, be connected with up outlet pipe 3 on the described water outlet 1-2, up outlet pipe 3 stretches out from installing stopper 2, the top of described up outlet pipe 3 is communicated with descending outlet pipe 5, and the top of described up outlet pipe 3 also is communicated with inlet hole 4.
Described descending outlet pipe 5 passes installing stopper 2 and stretch out outside the pump housing 1 lower end.
The top of described up outlet pipe 3 is communicated with descending outlet pipe 5 by connecting head 6.
Described inlet hole 4 is located at the top of connecting head 6.
Described water pump is wing pump.
Described installing stopper 2 is that periphery is columniform seal.
As shown in Figure 2, second embodiment of the present utility model, a kind of solar water heater hot water supercharging drain pump, comprise water pump, have water intake 1-1 and water outlet 1-2 on the pump housing 1 of water pump, the described pump housing 1 is provided with installing stopper 2, described water intake 1-1 is positioned at installing stopper 2 or is positioned on the installing stopper 2, be connected with up outlet pipe 3 on the described water outlet 1-2, up outlet pipe 3 stretches out from installing stopper 2, the top of described up outlet pipe 3 is communicated with descending outlet pipe 5, and the top of described up outlet pipe 3 also is communicated with inlet hole 4.
Described up outlet pipe 3 is communicated with descending outlet pipe 5 by connecting tube 7.
Described inlet hole 4 is located at the top of up outlet pipe 3.
As shown in Figure 3, the 3rd embodiment of the present utility model, wherein, described inlet hole 4 is located at the top of connecting tube 7.All the other structures are identical with second embodiment of the present utility model.
As shown in Figure 4, the 4th embodiment of the present utility model, wherein, described inlet hole 4 is located at the top of descending outlet pipe 5.All the other structures are identical with second embodiment of the present utility model.
As shown in Figure 5, the 5th embodiment of the present utility model, wherein, described inlet hole 4 is located at the top of connecting tube 7, and one-way valve 9 also is housed on the inlet hole 4.All the other structures are identical with second embodiment of the present utility model.
As shown in Figure 1, be that example illustrates installation of the present utility model and course of action with first embodiment of the utility model, during installation, installing stopper 2 of the present utility model is filled in the water tank 8 corresponding mounting holes of solar water heater, made inlet hole 4 be positioned at water tank 8 highest water levels and communicate with the upper part and with water tank 8 air.The function of hot water supercharging drain pump of the present utility model is: pump and pressurized hot water and can close hot water.When water pump is switched on, current suck from the water intake 1-1 of the pump housing 1, up send through up outlet pipe 3, to water tank 8 metal lines that are higher than solar water heater or the relative eminence of overflow layer, current are descending under the double action of water self gravitation and water-aspirator pressure then, use water spot from descending outlet pipe 5 to the user.After water pump quits work, because top or up outlet pipe 3 tops of connecting head 6 have the inlet hole 4 that communicates with the metal line upper air of water tank 8, remaining water can rely on the water self gravitation to flow out in the descending outlet pipe 5, thereby realize pipeline emptying surplus hot water purpose, and realize that next water is once opening out hot water.
