[0005] Furthermore, the manual mode monitors the operation through the water flow switch. When the hot water is turned on at any water tap for 2 seconds, it is turned off to trigger the circulation pump to work, and it automatically stops after reaching the preset temperature.

[0006] Furthermore, the automatic mode is to connect to WIFI and use the mobile phone APP to remotely control multiple timings or 7×24 hours automatic constant temperature operation.

[0007] The beneficial effects of the utility model are:

[0008] 1. Energy saving and environmental protection: Through intelligent control of hot water circulation, the original cold water in the hot water pipe is circulated to the cold water pipe through the return pipe, reducing water waste; the water pump automatically stops when the preset temperature is reached, effectively reducing energy consumption.

[0009] 2. Improve user experience: Hot water can be obtained without waiting, which significantly improves the user's daily experience and is especially suitable for mornings or peak water usage periods.

[0010] 3. Wide compatibility: It can be applied to various types of water heaters, especially traditional water heaters, greatly reducing the user's upgrade cost.

[0011] 4. High safety: It has an anti-dry burning function, which avoids the safety hazards caused by idling of the water pump and ensures the safe operation of the equipment.

[0012] 5. Intelligent Control: Supports two operating modes: "Automatic" and "Manual". Manual mode can be triggered by simply operating the tap, without additional intervention. In automatic mode, users can remotely control it through the mobile phone app to achieve various timing functions and automatic constant temperature operation.

[0013] 6. Silent operation: Adopt commercial-grade silent stainless steel water pump to ensure low noise when the system is running, keeping the home environment quiet and comfortable.

[0014] To sum up, the intelligent hot water circulation control system not only improves the functions of traditional water heaters, but also provides users with a convenient, safe and environmentally friendly hot water experience, and has broad market prospects and application value.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 The utility model provides a technical solution, an intelligent hot water circulation control system, including a circulation pump 5 and its control system. The water inlet of the circulation pump 5 is connected to the water heater 1 through a one-way valve 4, a temperature control probe 3 and a water flow switch 2 in sequence, and the water outlet is connected to the return pipe 6. The switch of the circulation pump 5 is controlled by the control system. The control system has two working modes: manual and automatic. In the manual mode, the power supply L line is connected to the thermostat 11 through the manual switch and then to the water flow switch 2, and then to the first intermediate relay 9 and the time relay 8, and then connected in parallel with the circulation pump 5; in the automatic mode, the power supply L line is connected to the thermostat 11 through the automatic switch and then to the mobile phone remote intelligent switch 7, and then to the second intermediate relay 10 and the time relay 8, and then connected in parallel with the circulation pump 5.

[0021] The manual mode is monitored by the water flow switch 2. When the hot water is turned on at any water tap for 2 seconds, the circulation pump 5 is turned off to start, and the circulation pump 5 stops automatically after reaching the preset temperature.

[0022] The automatic mode is to connect to WIFI and use the mobile phone APP to remotely control various timings or 7×24 hours automatic constant temperature operation.

[0023] The usage and working principle of this utility model are as follows:

[0024] 1. How to use manual mode: When the system is operating normally, press the control box switch to "manual". At this time, the operation is monitored by the water flow switch 2. Turn on the hot water at any water tap for 2 seconds and then close it to trigger the circulation pump to work. It will automatically stop when the preset temperature is reached.

[0025] 2. How to use automatic mode: Press the control box switch to "automatic". At this time, you can use the WIFI network mobile phone APP to remotely control the start directly or start within the set time period. If you do not set a specific start time, the default is 7×24 hours automatic constant temperature.

[0026] 3. Temperature Setting Method: Press the "Set" button to stop the temperature from flashing. Press the inverted triangle or equilateral triangle button to adjust the stop temperature. Press the "Set" button again to start the temperature from flashing. Press the inverted triangle or equilateral triangle button to adjust the start temperature. Select the start and stop temperatures as needed. The manual system will automatically operate according to the settings. If there is a large temperature deviation, you can perform temperature calibration: Press the "Calibrate" button. "ADJ" will be displayed in the upper right corner of the screen. Press the inverted triangle or equilateral triangle button to calibrate the temperature. The measured temperature can be calibrated to ±10°C.

[0027] 4. How to use the WIFI-connected mobile app for remote control: Download and install the Tuya Smart app, turn on Wi-Fi and Bluetooth on your phone, turn on the control box's switch to "Manual" to power on the device, open the Tuya Smart app to add the device, search for the device, click Add, and enter your Wi-Fi account and password. Click Next to configure the network. After successful network configuration, you can rename the device and click Finish to access the control page for related operations. You can remotely set the countdown, timer, loop timer, random timer, astronomical timer, or constant on / off via your phone. You can share with friends in various ways for multi-person control, or delete the primary account and give it to someone else.

[0028] 5. Working principle of anti-dry burning: When the circulation pump is started in "manual" and "automatic" modes, the time relay is energized and starts a 10-second countdown, which is equivalent to directly powering the circulation pump through the normally closed contacts of the time relay. If the water flow is normal after the countdown, the water flow switch is in the closed state, and the circulation pump can continue to work until it reaches the set temperature and stops automatically; if there is no water flow (i.e. water is stopped) through the water flow switch after the countdown, the water flow switch is in the open state, and the circulation pump stops immediately to prevent dry burning.
