Hot Air Steam Bath Device Localized Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hot air and steam bath devices require significant energy and time for preheating, often leading to uncomfortable and potentially overheating conditions, especially in the head and leg areas, and fail to efficiently distribute heat and steam for a relaxing experience.
Innovation Solution
A hot air and steam bath device design that minimizes the heating of air, directs steam-infused air primarily to the back and neck area through a permeable backrest, and uses a circulation system to temper and adjust the air temperature before re-circulating it, ensuring comfortable temperature levels are maintained without overheating the head or leg areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire room is preheated to comfortable temperature levels, then the thermal comfort is improved, but the energy consumption and preheating time increase significantly
Solution Approach 1:
The patent applies local quality by directing heated air and steam specifically to the backrest and seat areas where they are most needed for therapeutic effect, rather than heating the entire room. The backrest is designed with steam passages that deliver localized heat and moisture to the user's back and neck areas, reducing overall energy consumption while maintaining comfort in the treatment zone.
Solution Approach 2:
The patent segments the heating system into separate zones: a heating element for generating hot air, a steam generation system, and a distribution system that directs these to specific areas. The backrest is divided into multiple steam passages that can be independently controlled, allowing localized thermal treatment without heating the entire enclosure.
2Ease of operation
If the entire room is preheated to comfortable temperature levels, then the thermal comfort is improved, but the preheating time increases significantly
Solution Approach 1:
The patent applies local quality by directing heated air and steam specifically to the backrest and seat areas where they are most needed for therapeutic effect, rather than heating the entire room. The backrest is designed with steam passages that deliver localized heat and moisture to the user's back and neck areas, reducing overall energy consumption while maintaining comfort in the treatment zone.
Solution Approach 2:
The patent implements preliminary action by pre-heating the backrest and seat areas before the user enters, and by continuously circulating heated air and steam through the treatment zone during the session. This ensures immediate comfort upon entry without requiring prolonged preheating of the entire room.
3Power
If steam is generated at high temperature to ensure effective heating, then the heating efficiency is improved, but the risk of burns and overheating in head and leg areas increases
Solution Approach 1:
The patent applies local quality by directing heated air and steam specifically to the backrest and seat areas where they are most needed for therapeutic effect, rather than heating the entire room. The backrest is designed with steam passages that deliver localized heat and moisture to the user's back and neck areas, reducing overall energy consumption while maintaining comfort in the treatment zone.
Solution Approach 2:
The patent uses an intermediary circulation system that includes channels and ducts to control the distribution of hot air and steam. The heated air is circulated through controlled pathways that direct it to the backrest and seat areas, preventing direct contact with excessive heat in the head and leg areas. The system acts as a mediator between the high-temperature steam source and the user's body.
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 design reduces energy consumption, shortens preheating times, and provides a comfortable experience by ensuring mild overheating in the chest area and intensive heating in the back and shoulder areas while protecting the head and leg areas from excessive heat, enhancing the overall thermal relaxation effect.
Implementation Method 1
a device for generating warm air (hot air) is preferably provided on the floor
Implementation Method 2
The air can be intermittently mixed with steam through infusions
Implementation Method 3
The backrest or support area is not permeable to air or vapor

AI summary
The hot air or steam bath device has an air circulation channel (147) connected with a supply and distribution chamber (21) through a supply opening (47a). An air circulation unit (45) is provided for circulating the temperate air interspersed with steam generated from a primary temperature control unit (27,27a), and is designed such that the temperate air optionally interspersed with steam contained in the supply and distribution chamber is circulated in the air circulation channel through the supply opening and back into the supply and distribution chamber through an outlet opening (47b).
