Description

Technical Field

[0001] This invention relates to the technical fields of daily drinking water appliances, maternal and infant feeding appliances, and food temperature control appliances, specifically to a dual-cavity high-temperature sterilization active rapid cooling multi-scenario constant temperature device, system, and method of use. Background Technology

[0002] Traditional heating appliances can only heat and keep warm, without active and rapid cooling functions. Boiling water takes a long time to cool down naturally, and cannot reach the appropriate temperature for drinking, brewing, or eating immediately.

[0003] Commercially available constant temperature products only heat at low temperatures and cannot achieve 100℃ for complete sterilization, resulting in substandard hygiene for drinking water and complementary foods.

[0004] Ordinary cooling products rely on natural heat dissipation and phase change cooling, which result in slow cooling speed and poor temperature control accuracy, making them unsuitable for specific scenarios such as tea brewing, baby formula preparation, and cooling of complementary foods.

[0005] Existing products have limited functionality and cannot switch between multiple temperature control modes such as maternal and infant care, tea drinking, outdoor use, and daily drinking water on a single device, resulting in extremely poor versatility.

[0006] Existing dual-cavity devices mostly use a shared cavity for both heating and cooling, without an independent flow guiding structure. The residual heat from heating will continuously interfere with the cooling process, resulting in serious heat crosstalk and making it impossible to achieve both high-precision constant temperature and rapid cooling.

[0007] The mainstream rapid cooling equipment on the market all adopt a single-cavity integrated heating and cooling structure, which cannot realize a segmented closed-loop workflow of independent high-temperature sterilization in one cavity and independent semiconductor cooling in another cavity. Sterilization and cooling speed cannot be achieved at the same time, and it is not compatible with dual cooling scenarios for liquid drinking water and solid complementary food ingredients. Summary of the Invention

[0008] The purpose of this invention is to provide a dual-cavity high-temperature sterilization active rapid cooling multi-scenario constant temperature device, system, and usage method, which solves the problems of existing dual-cavity equipment, which mostly use a shared hot and cold cavity without an independent flow guiding structure. The residual heat from heating will continuously interfere with the cooling process, resulting in serious heat crosstalk, making it impossible to achieve both high-precision constant temperature and rapid cooling, and making it impossible to realize segmented closed-loop process.

Ventilation holes are provided on the housing on the right side of the silent cooling fan.

[0013] The transmission isolation layer includes a heat insulation layer, a main control microcontroller, a water pump, and an electrically controlled flow guide valve.

The upper part of the electrically controlled flow guide valve is connected to the interior of the upper liquid storage container through a pipeline. The two connection ports on the right side of the electrically controlled flow guide valve are respectively connected to the two water outlets outside the shell through pipelines.

[0014] Furthermore, the control panel 2 is electrically connected to the main control microcontroller. The main control microcontroller is electrically connected to the lower temperature sensor, thick film heating assembly, ultrasonic liquid level sensor, upper temperature sensor, cooling module, silent cooling fan, water pump, and electrically controlled flow guide valve. A power supply is provided on the left side of the lower liquid storage container. The power supply is electrically connected to the main control microcontroller. The power supply is equipped with a rectifier bridge, active PFC, and DC-DC conversion module to stabilize the output voltage and current, effectively filter current noise, avoid voltage surges, and maintain stable power supply during high-load operation.

[0015] Furthermore, a display screen is embedded in the upper left side of the control panel, a number of control buttons are provided on the lower side of the display screen, a number of status indicator lights are provided on the right side of the display screen, and a power button is provided to the right of the status indicator lights.

[0016] Furthermore, the left side of the electrically controlled flow guide valve is connected to the water inlet on the left wall of the housing via a pipeline.

[0017] Furthermore, the lower temperature sensor and the upper temperature sensor are NTC high-precision temperature acquisition modules, and the cooling module is a TEC semiconductor cooling component.

The control panel has preset temperature control programs for various scenarios: mother and baby mode, tea mode, daily drinking water mode, and complementary food mode. The main control microcontroller adjusts according to these preset temperature control programs, which include:

[0023] Mother and baby mode: 100℃ boiling and heat preservation for 30 seconds for sterilization → automatic diversion → rapid cooling to 45℃ constant temperature;
