[0047] The detection unit 3 includes a mounting plate 4, a detection control module 5, a power module 6, a water inlet module 7, a vacuum module 8, a drainage module 9 and a water outlet detection module 10;

[0048] The power module 6 is electrically connected to the detection control module 5, the water inlet module 7, the evacuation module 8, the drainage module 9 and the water outlet detection module 10, and the power module 6 is used to supply power to each module;

[0049] The detection control module 5 is electrically connected to the water inlet module 7, the vacuum module 8, the drainage module 9 and the water outlet detection module 10; the water inlet module 7 is used to provide the required cold water to the heating module to be detected; the vacuum module 8 is used to disconnect the water inlet pipeline so that the heating module to be detected can perform a water-free current detection; the water outlet detection module 10 is used to detect the water outlet volume and water outlet temperature of the heating module to be detected; the drainage module 9 is used to discharge the water outlet from the heating module in the water outlet detection module 10.

[0050] The present invention can realize multi-station detection and improve detection efficiency by cooperating with the rotating conveying unit 2 and multiple detection units 3. At the same time, the rotating conveying unit 2 can reduce the workers' handling work and reduce the workers' work intensity. The detection of the heating module is realized by multiple detection units 3, which can greatly improve the work efficiency compared with the existing single-station manual operation.

No manual participation in debugging is required, and the automatic detection work of the heating module can be realized. The test results are displayed by the detection control module 5, and the displayed results are intuitive.

[0051] Preferably, the water inlet module 7 includes a cold water tank 71 and a water inlet pipe 72; the cold water tank 71 is arranged on the mounting plate 4, one end of the water inlet pipe 72 is connected to the water inlet end of the heating module to be detected, and the other end of the water inlet pipe 72 extends into the cold water tank 71.

[0052] The water inlet pipe 72 is connected to the water inlet end of the water pump of the heating module to be tested. The water pump of the heating module works after receiving the signal of the detection control module 5, draws cold water from the cold water tank 71 through the water inlet pipe 72, and delivers the cold water to the heating element of the heating module for heating. When replacing the heating module, the water inlet pipe 72 connected to the heating module is disassembled. The water inlet module 7 does not actively supply cold water to the module, but provides the required cold water to the module. The heating module pumps water through its own water pump to ensure that it is full of cold water before subsequent testing.

[0053] Specifically, the detection device further includes a water replenishment module 11, the water replenishment module 11 includes a water replenishment solenoid valve 111 and a water replenishment tap 112, one end of the water replenishment tap 112 faces the water inlet module 7, and the other end of the water replenishment tap 112 is connected to the water replenishment solenoid valve 111;

[0054] The water inlet module 7 also includes a water shortage detection switch 73 , a water replenishment switch 74 and a water replenishment funnel 75 . The water replenishment funnel 75 is arranged on the cold water tank 71 and communicated with the cold water tank 71 . The water shortage detection switch 73 and the water replenishment switch 74 are arranged in the cold water tank 71 .

[0055] The water inlet module 7 and the water replenishment module 11 cooperate to realize the water replenishment work of the cold water tank 71. When the water shortage detection switch 73 detects that there is a lack of water in the cold water tank 71, it sends a signal to the detection control module 5; then, the rotating conveying unit 2 rotates the water shortage detection unit 3 to the water replenishment station. At this time, the output end of the water replenishment tap 112 is located above the water replenishment funnel 75, and the water replenishment switch 74 and the water replenishment solenoid valve 111 cooperate to make the water replenishment tap 112 add water to the cold water tank 71 until the water level meets the requirements of the water shortage detection switch 73.

[0056] Preferably, the water inlet pipe 72 includes a first connecting pipe 721, a second connecting pipe 722 and a third connecting pipe 723, the first connecting pipe 721, the second connecting pipe 722 and the third connecting pipe 723 are connected in sequence, one end of the first connecting pipe 721 is connected to the water inlet end of the heating module to be detected, the upper end of the third connecting pipe 723 is fixed on the cold water tank 71, and the lower end of the third connecting pipe 723 extends into the cold water tank 71; the second connecting pipe 722 and the third connecting pipe 723 are detachably connected;

[0057] The evacuation module 8 includes a drive motor 81 and a connecting block 82 ; the drive motor 81 is disposed on the cold water tank 71 , the output end of the drive motor 81 is connected to one end of the connecting block 82 , and the other end of the connecting block 82 is connected to the second connecting pipe 722 .

[0058] A sealing rubber ring is provided between the second connecting pipe 722 and the third connecting pipe 723 to ensure the sealing of the connection between the second connecting pipe 722 and the third connecting pipe 723, thereby avoiding leakage at the connection between the second connecting pipe 722 and the third connecting pipe 723 during water intake, which affects the water intake effect and causes errors in equipment detection.

[0059] The water inlet pipeline can be connected or disconnected by the evacuation module 8. When the water inlet pipeline is connected, the heating module works with water, and when the water inlet pipeline is disconnected, the heating module works without water, which is used to calibrate the water-free current. The motor drive can stabilize the movement of the second connecting pipe 722 to avoid the misalignment of the second connecting pipe 722 and the third connecting pipe 723 when they are connected again, resulting in the inability to connect or the appearance of a gap.

[0060] Specifically, the water outlet detection module 10 includes a water outlet pipe 101, a flow detection volume tank 102 and a flow detection water level switch 103. One end of the water outlet pipe 101 is connected to the water outlet end of the heating module to be detected, and the other end of the water outlet pipe 101 is arranged above the flow detection volume tank 102. The flow detection water level switch 103 is arranged in the flow detection volume tank 102.

[0061] The flow detection volume tank 102 is used to receive the water output from the heating module, and detects the amount of water output from the heating module through the flow detection water level switch 103, and performs calibration so that the error between the actual water output of the heating module water pump and the target water output is within 5%. When replacing the heating module, the water outlet pipe 101 connected to the heating module is disassembled.

[0062] Preferably, the drainage module 9 includes a drainage pipe 91 and a drainage solenoid valve 92 , one end of the drainage pipe 91 is communicated with the flow detection volume tank 102 , and the other end of the drainage pipe 91 is connected to the drainage solenoid valve 92 .

[0063] The drain pipe 91 is connected to the bottom of the flow detection volume tank 102, and a signal is sent to the drain solenoid valve 92 through the detection control module 5. The drain solenoid valve 92 opens to drain the water in the flow detection volume tank 102 through the drain pipe 91. When drainage is not required, the drain solenoid valve 92 is closed.

[0064] Specifically, the power module 6 includes a control switch, a strong current terminal and a weak current terminal; the control switch is used to turn on or off the power supply of the corresponding detection unit 3;

[0065] The strong electric terminal is electrically connected to the heating module to be detected, and is used to supply power to the heating component of the heating module to be detected;

[0066] The weak current terminal is electrically connected to the heating module to be detected, and is used to supply power to the heating module to be detected, and transmit the signal of the heating module to be detected to the detection control module 5.

[0067] In the present invention, the control switch adopts a 2P switch, which can disconnect the live wire and the neutral wire at the same time, without plugging and unplugging the power plug, thereby improving the safety of the equipment. The strong current terminal and the weak current terminal use different quick plug terminals according to different heating modules, which can realize the quick connection between the detection control module 5 and the corresponding port on the heating module, thereby improving the installation efficiency.

[0068] Preferably, the detection unit 3 further includes a rotation limit plate 31 , and the rotation conveying unit 2 is provided with a limit switch 21 .

[0069] The limit plate 31 is rotated on the detection unit 3. When the detection unit 3 is rotated to a predetermined position, the limit switch 21 detects the rotation of the limit plate 31, and the rotary conveying unit 2 stops working, so that the corresponding detection unit 3 stays at the position.

[0070] A detection method is applied to the above-mentioned heating module detection device, and the specific steps include:

[0071] Install the heating module and connect the corresponding terminals and pipelines;

[0072] The heating module is filled with cold water, and the water pump of the heating module is made to work at the default voltage and current value through the detection control module 5, and output water volume A. When the water output detection module 10 detects that the water output reaches the water volume A, the detection control module 5 outputs a signal to stop the heating module from outputting water, and records the current actual voltage and current values, and modifies the default voltage and current values ​​to the actual voltage and current values;

[0073] The detection control module 5 enables the water pump of the heating module to work and discharge water at a gradually increasing voltage value from 0 to 12V. The detection control module 5 obtains the working current of the water pump of the heating module at different voltage values, and modifies the theoretical voltage and current value of the water pump of the heating module to the corresponding voltage and current value.

[0074] The evacuation module 8 disconnects the water inlet pipeline, and makes the water pump of the heating module work at a gradually increasing voltage value from 0 to 12V through the detection control module 5. The no-load current of the water pump of the heating module under different voltage values ​​is obtained through the detection control module 5, and the theoretical water-free voltage and current value of the water pump of the heating module is modified to the corresponding voltage and current value;

[0075] The heating module is filled with cold water, and the detection control module 5 is used to make the heating module work and output water at a fixed temperature. The time of temperature rise and the voltage power of the heating module are used to determine whether the heating element of the heating module is normal and whether the heating power of the heating element meets the standard;

[0076] When the heating module is working, the detection control module 5 detects whether the heating module has a fault. If there is no fault, the heating module is filled with cold water. The water inlet pipeline is disconnected by the vacuum module 8. After confirming that there is no water in the heating module, the corresponding wiring terminals and pipelines are removed, and the heating module is removed. If a fault occurs, the fault is recorded after the heating module is removed.

[0077] The present invention detects the heating module through the detection unit 3. Before the heating module leaves the factory, 100% water flow detection is completed to ensure the stability of the product. By detecting whether the heating module is installed correctly and whether each electrical component is normal; calibrating the water pump flow to ensure that the water flow rate will not be uncontrollable due to the inconsistency of the water pump. The water pump's own flow error is ±10% or more. After the water pump flow rate is calibrated by this method, it can be controlled within the error range of ±5%; calibrating the water pump current, judging whether the heating module is short of water by the current when the water pump is working, and calibrating the water pump current before leaving the factory, grabbing the current curve of the water pump when working at full voltage and the current curve when full voltage is unloaded, ensuring that the heating module can quickly and accurately determine the actual water shortage when working, and avoiding the problem of dry burning; by detecting the temperature rise of the water temperature output by the heating module, it is determined whether each heating device is normal. The calibration step is performed by the detection control module 5. During the detection process, no manual control is required, which reduces the detection error caused by manual participation.

[0078] In the present invention, by controlling the heating element of the heating module, combined with the judgment of the water output and the water output temperature, the power of the heating element can be adjusted to make the next water output of the heating module more stable. The specific working principle is as follows: Figure 6 As shown. Among them, the water pump is controlled to discharge water. Since the flow rate of the water discharge is available, the water pump flow rate can be known through calibration. At different water discharge temperatures, the flow range is different. This range is calculated based on the power error of the heating element, the voltage fluctuation of the national power grid, the change in the inlet water temperature and other accumulated power errors. For example, at room temperature, the water discharge is not affected by power. Only one flow rate is used, a flow rate of 550m / min, and the water discharge temperature is 45℃. Affected by power, the water discharge flow rate is between 500-550ml / min; at a temperature of 85-98℃, the water discharge is most affected by power, and the water discharge flow rate is between 320-550ml / min. Control the heating element to output the corresponding power. Since the power of the heating element is unknown and the voltage is unknown, it can only be vaguely understood through the duty cycle.

[0079] The flow rate of the water pump has a flow curve by default, which can be obtained according to the specific water pump test. The curve is a line with a fixed curvature. If the corresponding flow rate is required, you only need to adjust the duty cycle to know the current flow value. However, because the curve positions of different water pumps are different, the specific curve position needs to be obtained through calibration. The actual power is unknown during the working process, but the heating element has a rated power. The default heating element is based on the rated power as the theoretical power, and then the temperature and flow rate during the water discharge process are used to see whether the power duty cycle should be adjusted.

[0080] Specifically, it is obtained through PID (proportional-differential-integral algorithm) through fuzzy algorithm. By detecting the outlet water temperature, the water pump flow rate is adjusted first, then the heating element power is adjusted, and then the water pump is adjusted in a cycle. The complex formula is adjusted by only adjusting one parameter within a certain period of time. Although the algorithm formula is very complex, there is only one variable, so it is more accurate and convenient.

[0081] The water pump flow is more accurate. Figure 7 As shown, the pump current is accurate as Figure 8 shown.

9. A detection method, characterized in that: A heating module detection device applied to any one of claims 1 to 8, the specific steps comprising: Install the heating module and connect the corresponding terminals and pipelines; The heating module is filled with cold water. The detection control module is used to make the water pump of the heating module work at the default voltage and current value and output water volume A. When the water output detection module detects that the water output reaches the water volume A, the detection control module outputs a signal to stop the heating module from outputting water, records the current actual voltage and current values, and modifies the default voltage and current values ​​to the actual voltage and current values; The detection control module enables the water pump of the heating module to work and discharge water at a gradually increasing voltage value from 0 to 12V, obtains the working current of the water pump of the heating module at different voltage values ​​through the detection control module, and modifies the theoretical voltage and current value of the water pump of the heating module to the corresponding voltage and current value; The evacuation module disconnects the water inlet pipeline, and the water pump of the heating module works at a gradually increasing voltage value from 0 to 12V through the detection control module. The no-load current of the water pump of the heating module under different voltage values ​​is obtained through the detection control module, and the theoretical water-free voltage and current values ​​of the water pump of the heating module are modified to corresponding voltage and current values; The heating module is filled with cold water. The detection control module makes the heating module work and outputs water at a fixed temperature. The temperature rise time and the voltage power of the heating module are used to determine whether the heating element of the heating module is normal and whether the heating power of the heating element meets the standard. When the heating module is working, the detection control module detects whether the heating module has a fault. If there is no fault, the heating module is full of cold water. The water inlet pipe is disconnected by the vacuum module. After confirming that there is no water in the heating module, the corresponding wiring terminals and pipes are removed, and the heating module is removed. If a fault occurs, the fault is recorded after the heating module is removed.
