The shell 1 of the utility model is internally provided with a self-priming pump 5, a centrifugal booster pump 10 and an electric control system 11, the self-priming pump 5 is provided with a self-priming pump water inlet 501 and a self-priming pump water outlet 502, the self-priming pump 5 can adopt a direct current electric diaphragm pump in the prior art, namely, the self-priming pump 5 can be arranged at a position higher than the liquid level, and the self-priming pump 5 can still pump water under the condition that air is in a pipeline connected with the self-priming pump water inlet 501. The centrifugal booster pump 10 is provided with a booster pump water inlet 1001 and a booster pump water outlet 1002, the centrifugal booster pump 10 is in the prior art, and the centrifugal booster pump 10 belongs to a centrifugal pump, so that the centrifugal booster pump 10 can operate for a long time, and has the characteristics of relatively large flow and high efficiency, but before the centrifugal pump operates, a pump cavity and a water inlet pipeline of the centrifugal pump need to be filled with water.
As shown in fig. 1, heater water inlet 201 passes through heater inlet tube 4 with booster pump delivery port 1002 to be connected, booster pump water inlet 1001 passes through booster pump inlet tube 14 with water heater water inlet 8 and is connected, self priming pump water inlet 501 passes through self priming pump inlet tube 6 with water heater water inlet 8 and is connected, self priming pump delivery port 502 passes through self priming pump outlet pipe 7 with booster pump water inlet 1001 and is connected, booster pump inlet tube 14 is equipped with the check valve 13 that is used for preventing 5 rivers refluxes of self priming pump operation formation to water heater water inlet 8, heater inlet tube 4 is equipped with flow sensor 9, flow sensor 9 is prior art, flow sensor 9 specifically can be hall effect formula water flow sensor, this type of flow sensor mainly is equipped with rivers rotor subassembly and hall element, rivers drive rivers rotor rotates, the last permanent magnet of rivers rotor blade makes hall element produce the corresponding signal of electric signal with rivers rotor speed. Electric control system 11 is connected with flow sensor 9 electricity, and electric control system 11 control connection self priming pump 5, centrifugal booster pump 10 and heater 2, and water heater water inlet 8 is equipped with into water temperature sensor 15, and electric control system 11 electricity is connected into water temperature sensor 15.
The working principle of the utility model is explained below: the water heater inlet 8 is connected to an external water pipe, which is connected to the water heater inlet 8 and must be inserted below the bath level. The water outlet 12 of the water heater is connected with and provided with another external water pipe, the pipe orifice of the external water pipe connected with the water outlet 12 of the water heater can be arranged above the liquid level of the bathtub, and the water flowing out of the water outlet 12 of the water heater can flow back into the bathtub only by ensuring. When the electric water heater is started, the electric control system 11 firstly controls the self-priming pump 5 to operate, the self-priming pump 5 pumps water in a bathtub, and water flow fills the water inlet pipe 6 of the self-priming pump, the water outlet pipe 7 of the self-priming pump, the pump cavity of the centrifugal booster pump 10 and the water inlet pipe 4 of the heater, as shown in fig. 1, the check valve 13 prevents the water flow flowing from the water outlet pipe 7 of the self-priming pump to the centrifugal booster pump 10 from flowing back to the water inlet 8 of the water heater, when the water flow detected by the flow sensor 9 reaches the start-allowed flow value of the centrifugal booster pump 10, the electric control system 11 controls the centrifugal booster pump 10 to start to operate, the electric control system 11 immediately controls the self-priming pump 5 to stop operating and starts the heater 2, and the purpose that the electric control system 11 stops the self-priming pump 5 is to avoid damage caused by long-time use of the self-priming pump 5. In the working process of the centrifugal booster pump 10, water flow directly enters the booster pump water inlet 1001 from the water heater water inlet 8 through the heater water inlet pipe 4, and unnecessary resistance on the water flow generated by the operation of the centrifugal booster pump 10 due to the fact that the water flow must pass through the self-priming pump 5 is avoided. The centrifugal booster pump 10 then continuously pumps water from the bath into the heater 2. After the heater 2 heats the water flow, the water flow flows back to the bathtub from the water outlet 12 of the water heater. When flow sensor 9 senses that the water of inhaling up can not satisfy centrifugal booster pump 10 normal work, electrical system 11 can open self priming pump 5 automatically in order to reach the required flow of satisfying centrifugal booster pump 10 operation, and self priming pump 5 and centrifugal booster pump 10 so cooperate the circulation work. The centrifugal booster pump 10 with large flow and good durability is combined with the self-sucking pump 5 with the self-sucking function, so that active water inlet is realized, namely water can be actively pumped under the condition that the water inlet 8 of the water heater has no water inlet pressure, and the centrifugal booster pump can be arranged at a position higher than the liquid level, so that the centrifugal booster pump is convenient to arrange and install. The heating bathtub can heat water in the bathtub, and people can take a bath in winter, so that the temperature of the water in the bathtub is quickly reduced. When the inlet water temperature of the water inlet 8 of the water heater monitored by the inlet water temperature sensor 15 is lower than the set value of the electronic control system 11, the electronic control system 11 controls the heater 2 to start heating, and when the inlet water temperature of the water inlet 8 of the water heater monitored by the inlet water temperature sensor 15 is higher than or equal to the set value of the electronic control system 11, the electronic control system 11 does not start the heater 2, so that the water body in the bathtub achieves the effect of keeping the temperature constant.
When the water inlet 8 of the water heater is connected with a tap water pipe for use, namely the water heater needs to realize the functions of a common water heater, the self-sucking pump 5 and the centrifugal booster pump 10 can be kept in a stop state, and tap water flows through the self-sucking pump 5 and the centrifugal booster pump 10 from the water pressure of the tap water, then enters the heater 2 and flows out from the water outlet 12 of the water heater. The electric water heater is not limited to be applied to bathtub occasions, such as fish tanks, water pools and the like, and can also be used, so that the electric water heater has wider adaptability compared with the electric water heater in the prior art.
Further, as shown in fig. 1, an outlet water temperature sensor 16 is arranged at the water outlet 12 of the water heater, the electric control system 11 is electrically connected to the outlet water temperature sensor 16, and when the outlet water temperature sensor 16 senses that the temperature of the water flowing through the water outlet 12 of the water heater is too high, the electric control system 11 controls the heater 2 to stop heating according to the signal of the outlet water temperature sensor 16, so as to play a role in protection and avoid scalding.
Further, because centrifugal booster pump 10 compares with self priming pump 5 and has the advantage that flow is big, the internal diameter through setting up booster pump inlet tube 14 is greater than the internal diameter of self priming pump inlet tube 6 to even the rivers that centrifugal booster pump 10 was inhaled and is come up do not pass through self priming pump inlet tube 6, self priming pump 5 and self priming pump outlet pipe 7, also be favorable to booster pump inlet tube 14 can satisfy the demand of centrifugal booster pump 10's rated flow.
In conclusion, the electric water heater has a self-suction function, active water inlet can be achieved, the electric control system 11 coordinates the self-suction pump 5 and the centrifugal booster pump 10 to work alternately, the self-suction pump 5 and the centrifugal booster pump 10 are durable, and the electric water heater has a constant temperature function and excellent use experience.
