Dual-Pipe Electric Heater Layout for Simultaneous Water and Steam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric heaters for preparing hot beverages require two separate units to heat water and steam simultaneously, leading to excessive dimensions and costs, and can only heat one fluid stream at a time, limiting their efficiency and versatility.
Innovation Solution
An electric heater with a metal body containing two distinct pipes and three heating stretches, where two heating stretches heat both pipes efficiently and the third stretch primarily heats one pipe, allowing simultaneous heating of hot water and steam with improved energy efficiency and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate electric heaters are used to heat water and steam simultaneously, then both functions can be performed, but the overall dimensions and costs become excessive
Solution Approach 1:
The patent combines two separate electric heaters into a single integrated unit with a common heating element that serves both the water heating function and the steam generation function. The heating element is positioned to transfer heat to both the water reservoir and the steam generation chamber simultaneously, thereby achieving dual functionality while reducing overall device volume and component count.
Solution Approach 2:
The single heating element is designed to perform multiple functions: it heats water for beverage preparation and simultaneously generates steam for frothing or steaming. This multi-functional approach allows one component to replace what would traditionally require two separate components, reducing device complexity and space requirements.
2Volume of moving object
If a single tube is used for heating fluid, then the device is compact, but only one fluid stream can be heated at a time
Solution Approach 1:
The internal structure of the single heater is segmented into distinct heating zones or pathways. The heating element creates separate thermal zones that can independently heat different fluid streams passing through different portions of the device, allowing simultaneous multi-stream heating while maintaining a compact external form factor.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement within the single heater body to accommodate multiple fluid pathways. By arranging heating zones in different spatial dimensions and orientations within the compact housing, the device can process multiple fluid streams simultaneously without increasing external dimensions.
3Device complexity
If sequential heating of two fluid streams is used, then a single tube suffices, but the heating efficiency and productivity are reduced
Solution Approach 1:
The heating element operates continuously and simultaneously on multiple fluid streams rather than switching between them sequentially. Both water heating and steam generation occur at the same time, maximizing the utilization of the heating element and eliminating idle time, thereby significantly improving productivity and energy efficiency.
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
Enables simultaneous heating of two fluid streams with reduced energy consumption and compact size, allowing for flexible heating management and efficient production of both hot water and steam.
Implementation Method 1
the first heating stretch and the second heating stretch are adapted to heat the first pipe and the second pipe by transferring heat through the metal body
Implementation Method 2
one or two resistors, which heat the tube and therefore the fluid flowing therein

AI summary
An electric heater including a metal body, in which a first pipe and a second pipe are provided in the metal body. The first pipe and second pipe are mutually distinct so as to be crossed by two distinct flows of fluid to be heated. A first heating stretch, a second heating stretch and a third heating stretch are arranged in the metal body. The first pipe and the second pipe are arranged between the first heating stretch and the second heating stretch. The third heating stretch is proximal to the second pipe and distal from the first pipe. The second pipe is arranged between the first pipe and the third heating stretch.
