Technical Field

[0001] This utility model relates to water recirculation devices, and more particularly, to an intelligent integrated household water recirculation device. Background Technology

[0002] Currently, in the field of domestic hot water circulation, the circulation of hot water in domestic hot water pipes is mainly achieved through the cooperation of pumps and temperature and flow sensors, so as to keep hot water available immediately. Most existing technologies use external temperature and flow sensors, which are connected to the pump through connectors or installed on the connecting pipes. This results in a complex structure, difficult assembly, and a large product size, which is not conducive to on-site installation in the limited space of existing homes. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an intelligent integrated household water recirculation device with a reasonable structural design.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A smart integrated household water recirculation device includes a water pump body, a flow detection module, and a control module. The water pump body is equipped with an inlet pipe and an outlet pipe. The flow detection module is a Hall effect flow sensor, including a magnetic rotor guide tube and a Hall effect sensing element. The magnetic rotor guide tube is disposed inside the inlet pipe. The Hall effect sensing element is disposed outside the inlet pipe and is used to sense whether the rotor inside the magnetic rotor guide tube is rotating and output a corresponding detection signal.

The pressure block enters the slot and presses the mounting ring into the slot.

[0013] Preferably, the mounting ring is provided with an annular groove, and a sealing ring is nested in the annular groove.

[0014] The main technical effects of this utility model are reflected in the following aspects:

[0015] The use of a Hall effect flow sensor built into the inlet pipe to detect flow, and the integration of a temperature sensor into the pump body, results in a simple structure and well-controlled volume for the entire water return device.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0024] Reference Figure 1 , Figure 2This embodiment aims to provide an intelligent integrated household water recirculation device, which includes a top cover 21, a base 1, a water pump body 43, a flow detection module, and a control module. The control module is electrically connected to the water pump body 43 and is used to control the start and stop of the water pump body 43.

[0025] The upper cover 21 and the base 1 are detachably connected to each other. Both have screw holes 12 inside. After the upper cover 21 and the base 1 are fastened together, the upper cover 21 and the base 1 can be fixed by inserting screws into the screw holes 12.

[0026] Reference Figure 3 , Figure 4 The water pump body 43 is equipped with an inlet pipe 41 and an outlet pipe 42, which are connected through the pump chamber of the water pump body 43.

[0027] The flow detection module is a Hall effect flow sensor, including a magnetic rotor guide tube and a Hall effect sensing element 52. The magnetic rotor guide tube is disposed inside the inlet pipe 41. An installation groove 47 is provided on the outside of the inlet pipe 41, and the Hall effect sensing element 52 is disposed within the installation groove 47. When fluid flows through the inlet pipe 41, the rotor inside the magnetic rotor guide tube 51 rotates, thereby triggering the Hall effect sensing element 52 to output a corresponding detection signal. The Hall effect sensing element 52 is electrically connected to the control module to transmit the detection signal to the control module. When fluid flows through the inlet pipe 41, the control module immediately controls the water pump body 43 to operate and begin pumping fluid.

[0028] The water pump body 43 is also provided with a first mounting hole 46 communicating with the pump chamber 431. A temperature sensor is provided in the first mounting hole 46. The temperature sensor can be used to detect the temperature of the water pump body 43 and transmit it to the control module. When used for HVAC water supply or return, it can be set to start or stop when the temperature is lower than a preset threshold, and stop or start when the temperature is higher than another preset threshold.

[0029] In addition, a check valve is installed in the outlet pipe 42 to effectively prevent fluid backflow, which could cause the impeller to reverse or cross-contamination.

[0030] A second mounting hole 48 is provided on the water outlet pipe 42, and the second mounting hole is located downstream of the check valve 48; a pressure sensor is provided in the second mounting hole 48, and the pressure sensor is electrically connected to the control module.

[0031] Reference Figure 2Both the inlet pipe 41 and the outlet pipe 42 are equipped with mounting rings 45 on their outer sides. The upper end of the base 1 has locking slots 11 on its front and rear sides that fit the mounting rings 45. The upper cover 21 has corresponding pressure blocks 211 that fit the mounting rings. The pressure blocks 211 enter the locking slots 11 and press the mounting rings 45 tightly within them. Additionally, the mounting ring has an annular groove 451, within which a sealing ring is nested. During installation, first, the sealing ring (not shown) is inserted into place. Then, the two mounting rings 45 are inserted into the locking slots 11. Finally, the upper cover 21 is fastened to the base 1, causing the pressure blocks 211 to also enter the locking slots 11 and press tightly against the mounting rings 45. The sealing ring prevents resonance between the pump and the housing, reducing noise during pump startup.

[0032] The control module includes a PCB board and components integrated on the PCB board. The PCB board is fixed inside the top cover 21, specifically by screws.

[0033] The top cover 21 is fixed to the base 1 with screws. The top cover 21 has several through holes. The control module also integrates a display unit and control buttons. The display unit can display parameters such as temperature, pressure, and flow rate. The operation buttons and display unit extend through the through holes in the top cover 21. A transparent cover 22 is positioned at the location of each through hole, sealing it off. The operation buttons are flush with the transparent cover 22. The operation buttons are capacitive buttons; the user can activate them simply by touching the surface of the transparent cover 22.

[0034] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
