Solution Overview
Problem
Conventional microwave treatment devices face challenges in achieving desired heating performance for objects of various shapes and sizes due to conflicting limitations in heater installation and microwave radiation regions, leading to inefficient or uneven heating.
Innovation Solution
The microwave treatment device incorporates a heater positioned separately from the heating chamber wall with a predetermined distance, allowing the space between the heater and the wall to act as a waveguide for microwave propagation, enabling a larger heater installation area with a smaller antenna and expanding the microwave radiation region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heater installation region is enlarged to improve heater heating performance, then the microwave radiation region is reduced, but this leads to decreased heating efficiency and uneven heating for objects placed in a wide range
Solution Approach 1:
The patent utilizes the space dimension between the heater and heating chamber wall to enable microwave propagation. By positioning the heater at a predetermined distance from the wall surface, a waveguide path is created that allows microwaves to reach areas behind and around the heater, effectively expanding the radiation region without reducing heater installation space.
2Reliability
If the microwave radiation region is enlarged to improve microwave heating performance, then the heater installation region is reduced, but this results in insufficient heating performance by the heater
Solution Approach 1:
The patent creates a three-dimensional microwave propagation path by utilizing the space between the heater and wall. This allows the microwave radiation region to extend beyond the two-dimensional plane occupied by the heater, enabling wide-area heating while maintaining adequate heater installation space for reliable heating performance.
3Area of stationary object
If a small antenna is used to secure heater installation space, then the microwave radiation capability is limited, but this reduces the ability to heat objects of various shapes and sizes
Solution Approach 1:
The patent employs the spatial dimension between the heater and wall to create waveguide paths that extend microwave radiation throughout the heating chamber. This three-dimensional propagation approach enables a compact antenna configuration to achieve comprehensive heating coverage for objects of various shapes, sizes, and positions.

AI summary
A microwave treatment device includes a heating chamber for accommodating a heating target object, an oscillation unit for generating a microwave, a radiation unit, and a heater. The heater is disposed in the heating chamber separately from a wall surface of the heating chamber by a predetermined distance so as to include a flat surface facing the wall surface. The radiation unit is disposed in the heating chamber, and radiates a microwave to the space between the heater and the wall surface so that the microwave propagates through the space. In the present aspect, using a small antenna, the installation region of the heater can be set large, and the radiation region of the microwave can be extended. As a result, the heating performance by the heater and the heating performance by the microwave can be reconciled.
