Mattress Microwave Drying to Eliminate Interior Residual Moisture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for drying mattresses, particularly in hotels and hospitals, are inefficient as they primarily rely on external warm air flow, which does not effectively dry the interior of the mattresses.
Innovation Solution
The use of electromagnetic waves, specifically microwaves with wavelengths of a few millimeters to a few decimeters, to dry mattresses from the inside out, focusing energy density on the mattress core and allowing for continuous, homogeneous drying, while also disinfecting by converting radiation energy into thermal energy that evaporates treatment liquids and kills germs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electromagnetic waves are used to dry mattresses from the inside, then drying effectiveness and speed are improved, but device complexity increases
Solution Approach 1:
The patent replaces the conventional mechanical drying system (external air circulation and heating) with an electromagnetic field-based system. Microwave generators or electromagnetic radiation sources directly penetrate the mattress material to heat and evaporate moisture from the interior, eliminating the need for complex air flow channels and external heating mechanisms while dramatically improving drying speed and effectiveness.
2Manufacturing precision
If electromagnetic waves are focused to achieve maximum energy density inside the mattress, then drying homogeneity is improved, but energy consumption increases
Solution Approach 1:
The patent applies electromagnetic radiation with varying intensity distributions across different regions of the mattress. By focusing energy density locally where moisture content is highest and adjusting the electromagnetic field parameters, the system achieves homogeneous drying throughout the mattress interior while optimizing energy utilization and avoiding excessive overall energy consumption.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method enables rapid and thorough drying of both the surface and interior of mattresses, ensuring effective disinfection by vaporizing treatment liquids and removing residual moisture, thus improving hygiene and efficiency in mattress treatment processes.
Implementation Method 1
The electromagnetic waves also reach the inside of the mattresses, which allows them to be completely dried in a relatively short time. The drying takes place by heating a treatment liquid or water inside the mattress and preferably evaporating it.
Implementation Method 2
The energy of the electromagnetic radiation is thus converted into thermal energy. The hot water vapor generated in this way escapes through the mattress to the outside.

AI summary
The invention relates to a method and a device for treating mattresses (11) or the like. Mattresses (11) or similar items such as pillows, cushions, or textile covers, which are used, for example, in hotels or hospitals, must be washed regularly. Particularly after use in hospital beds, the mattresses (11) can be heavily soiled and must be thoroughly cleaned and, if necessary, disinfected. Since mattresses (11) are relatively thick, it sometimes happens that the interior of the mattresses (11) still retains some residual moisture after the drying process. This residual moisture is an ideal environment for the formation of harmful germs or bacteria. The invention therefore provides that the washed mattresses (11) are dried thoroughly, including the interior, by irradiation with microwaves (25).
