[0022] The water pump is designed in the waterway system to enable the water to flow through the water heating module stably and quickly, avoiding uneven heating or insufficient water temperature caused by insufficient water pressure or unstable water flow, and improving the stability of the outlet water temperature and the user experience.

[0023] The water heating module adopts a segmented heating design, which can realize step-by-step heating or full-segment heating according to actual needs, ensuring that the water temperature meets the preset requirements while reducing unnecessary power consumption. At the same time, the modular design can better realize temperature control, avoiding safety hazards caused by excessive temperature.

[0027] Further, the cooking utensil heating device is an electric ceramic stove, and the cooking utensil heating area of the base is provided with a notch, and the heating part of the electric ceramic stove is exposed outside the notch.

The exposed heating part of the electric ceramic stove ensures uniform temperature distribution in the heating area, avoiding local temperature difference problems that may occur in traditional heating methods, making the tea set, tableware, and other utensils in the cooking utensils heat more evenly, and improving the disinfection efficiency.

[0029] The exposed design of the heating part of the electric ceramic stove ensures that heat mainly acts on the cooking utensils themselves, reducing the risk of heat conduction to the interior of the base, which helps to prolong the service life of the internal components of the equipment. At the same time, this design reduces unnecessary heat loss, ensuring efficient heating and saving energy.

[0030] Through the design of the notch in the base, the electric ceramic stove can be more compactly embedded in the equipment, ensuring good contact between the heating part of the electric ceramic stove and the cooking utensils, and reducing the occupation of additional space, in line with the design concept of compact and multifunctional equipment, and suitable for various scenes.

[0038] Due to the introduction of the spiral body structure, the heating pipe body can be placed at any angle without affecting its heating performance. Users are no longer limited by the placement of the heating pipe body, increasing the convenience of installation and use.

[0039] The water channel formed by the spiral body in the heating pipe body ensures that even small flow of water can be quickly guided through, thereby avoiding the dry burning problem of traditional heating pipe bodies when the water flow supply is insufficient, and improving the use safety.

[0040] The spiral body design enables the water flow to flow along a specific path, improving the flow speed and heating efficiency of the water. In this way, not only the heating effect of the water heater is improved, but also hot water can be provided more quickly.

This design can quickly heat water to the required temperature without significantly increasing the power of individual modules, and the overall heating efficiency is greatly improved compared to traditional single-module systems.

This heating method uses the principle of eddy current, and the heat is generated more quickly and uniformly, improving the heating efficiency of the water heater.

[0056] Due to the high efficiency and low energy loss of the eddy current heating method, the electric energy can be better utilized, the heating process is more energy-saving and environmentally friendly, which helps to reduce energy consumption and environmental pollution.
