Multifunctional Electric Pot with Interchangeable Lids and Inner-Pot Temperature Sensing

The problem

Countertop space in home kitchens and small commercial prep areas is limited. Buyers who want to pressure cook, air fry, steam, and simmer traditionally need a separate appliance for each method, which increases equipment costs and storage requirements. Even when a single base unit offers multiple functions, routing electrical power safely to removable lids while maintaining accurate temperature feedback from inside the cooking vessel remains difficult. External sensors on the heating plate often lag behind the actual food temperature, and exposed contacts near the rim pose insulation challenges during cleaning or when liquids spill.

The solution

This multifunctional pot addresses those issues by combining a single heating base with a removable inner pot and a set of interchangeable lids.

1. The heating part includes a main body housing a heating body, a temperature measuring component, and a control board assembly capable of controlling the heating power.
2. An insulated main body connector is mounted on the base, carrying a conductive terminal that is electrically connected to the control board assembly.
3. The inner pot sits on the heating body. A temperature measuring device on one side of the inner pot detects its internal temperature and connects electrically to the conductive terminal on the main body when assembled.
4. Different lids convert the base and inner pot into specific appliances: a pressure cooker lid seals it for pressure cooking; an air fryer lid containing a fan and heat pipe draws power through the conductive terminals; a pot cover paired with a ceramic insert creates an electric cup pot; and a steamer tray stacks on top for steaming.

Who it is for

• Small appliance brands looking to offer a modular cooking system under their own label without developing the base architecture from scratch.
• Amazon private-label sellers seeking a multi-function kitchen product that reduces the number of SKUs a customer needs to buy for different cooking styles.
• Wholesalers and distributors supplying housewares retailers who want a single boxed product that replaces several countertop appliances.
• Corporate gifting and promotional buyers needing a versatile kitchen item that appeals to a wide range of recipients in compact living spaces.

How it works

The main parts

Operating steps

1. Seat the inner pot on the heating body of the main body. The temperature measuring device on the pot aligns with the conductive terminal on the insulated main body connector, establishing an electrical path to the control board assembly.
2. Select a lid based on the cooking method. For example, attach the pressure cooker lid to seal the pot, or place the air fryer lid so its fan and heat pipe connect through the conductive terminals.
3. Power on the unit. The control board assembly receives temperature signals from both the base temperature measuring component and the inner-pot temperature measuring device.
4. Cook. The control board adjusts the heating power accordingly. If using the air fryer lid, power is routed through the terminals to operate the fan and heat pipe inside the lid.
5. Swap lids after cooling to change the cooking function, using the same base and inner pot.

Applications

Home meal preparation

Home cooks with limited counter space can replace a standalone pressure cooker, air fryer, and steamer with one base unit. Swapping the lid changes the cooking method while keeping the same inner pot, reducing cleanup and storage needs.

Dormitories and studio apartments

Students and renters often lack full kitchens. A single multifunctional pot allows them to steam vegetables, pressure cook grains, or air fry snacks using one electrical outlet and minimal storage space.

Small catering and food stalls

Vendors preparing varied menus benefit from a single heating base that adapts to different tasks throughout the day. They can switch from steaming buns in the morning to pressure cooking stews in the afternoon without changing appliances.

RV and mobile living

Space and weight are restricted in recreational vehicles. Carrying one base, one inner pot, and a few lightweight lids takes up less room than packing multiple dedicated cooking devices, while the shared electrical connection simplifies wiring.

Where it is less suitable

• Heavy-duty commercial kitchens - continuous high-volume service requires dedicated, industrial-grade equipment built for constant operation rather than modular household bases.
• Outdoor camping without power - the unit relies on mains electricity for the heating body and control board, making it unsuitable for off-grid fire-based cooking.
• Specialized baking - the design focuses on stovetop-style methods like pressure cooking, steaming, and air frying rather than conventional oven baking with enclosed radiant heat.
