[0024] The pump integrated assembly 1 in the present invention includes an electric three-way valve 14, a pump body 10, a heating component 11, a return pipe 16, a clean water pipe 15, a water inlet pipe 12 and a water outlet pipe 13, which are integrated into a module as a whole. The pump body 10 is used to provide flow power to the liquid flowing to the cleaning component 6. The pump body 10 can be a centrifugal pump or a DC pump. The inner cavity is mainly used to set the active parts for pumping liquid. The active parts can be rotating parts such as blades or impellers, and of course, other parts such as plungers. The heating component 11 is used to heat the fluid flowing to the cleaning component 6.

[0025] The electric three-way valve 14 is provided with a first inlet 141, a second inlet 142 and a valve outlet 143. One end of the return pipe 16 is connected to the first inlet 141, and the other end is connected to the outlet of the return tank 3. One end of the clean water pipe 15 is connected to the second inlet 142, and the other end is connected to the outlet of the clean water tank 2.

[0027] In the present invention, one end of the water inlet pipe 12 is connected to the valve outlet part 143, and the other end is connected to the pump inlet part 104. The first end of the water outlet pipe 13 is connected to the pump outlet part 102, and the other end can be connected to the cleaning component 6 in the inner tank 5.

[0028] Through the above settings, a pump integrated component is provided, which includes an electric three-way valve 14, a pump body 10 and a heating component 11. The heating component 11 is integrally arranged on the pump body 10, and is connected between the electric three-way valve 14 and the pump body 10 through the water inlet pipe 12 respectively. The product has a high function integration degree and a relatively compact structure.

[0029] When the electric three-way valve 14 is in the first working position, the water in the return water tank 3 enters the electric three-way valve 14 through the first inlet part 141, enters the pump inlet part 101 through the valve outlet part 143, is heated by the heating component 11 limited to the pump body 10, and flows out from the pump outlet part 102 to the cleaning component 6 to clean the inner tank 5; in this state, the water tank 2 is disconnected from the pump inlet part 101 of the pump body 10 through the electric three-way valve 14;

[0030] When the electric three-way valve 14 is in the second working position, the water in the water tank 2 enters the electric three-way valve 14 through the second inlet part 142, enters the pump inlet part 101 from the valve outlet part 143, is heated by the heating component 11 limited to the pump body 10, and flows out from the pump outlet part 102 to the cleaning component 6 to perform secondary cleaning on the inner tank 5. In this state, the return water tank 2 is disconnected from the pump inlet part 101 of the pump body 10 through the electric three-way valve 14; Through this design, the pump integrated component 1 with a high function integration degree and a relatively compact structure can be applied to the cleaning pipeline system of the steam baking equipment, and the heating efficiency can be relatively improved.

[0031] In a specific embodiment, the pump body 10 is provided with an inner cavity, and the heating component 11 is integrated on the outer surface of the cavity wall surrounding the inner cavity, which is convenient for the installation and maintenance of the heating component 11. Of course, the heating component 11 can also be integrated inside the cavity wall of the pump body 10.

[0032] In the embodiment of the present invention, the heating component 11 is located on the cavity wall between the water inlet pipe 12 and the water outlet pipe 13. This arrangement is conducive to better heating the liquid and improving the efficiency of cleaning the inner tank 5.

[0033] In the embodiment of the present invention, the heating component 11 may include a heating tube, and the heating tube is wound around the outer wall of the cavity. The heating tube has a simple structure and is relatively easy to install.

[0034] In a specific embodiment, one end of the return pipe 16 is connected to the first inlet 141 through a clamp, and one end of the clean water pipe 15 is connected to the second inlet 142 through a clamp.

The second end of the water outlet pipe 13 can also be connected to the cleaning component 6 through a clamp or threaded connection.

[0036] In the present invention, when the electric three-way valve is in the first working position or the second working position, the electric three-way valve is in a power-off state. In this way, the electric three-way valve 14 is automatically powered off after being switched into position, thereby reducing power consumption.

[0037] In addition, the positions of the first inlet 141, the second inlet 142 and the valve outlet 143 of the electric three-way valve 14 can be determined according to the specific application environment. Similarly, the positions of the clean water pipe 15 and the return water pipe 16 can be reasonably set according to the specific application environment. Figures 2 to 4 Specific implementations of different postures of the clean water pipe 15 and the return water pipe 16 are given.

[0038] In a specific embodiment, the cleaning pipeline control system further includes a filter screen 4 for filtering the liquid entering the return water tank 3.
