Dishwasher Booster Tank Layout for Heat Loss and Space Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Booster tanks for dishwashing machines lose energy by radiating heat to ambient air, leading to inefficiency and increased energy consumption, and require additional space for installation, complicating service access.
Innovation Solution
A booster tank design where the heating element is integrated within the housing and connected to the dishwashing machine's tub, allowing for efficient heat transfer to the wash water through conduction via fins and minimizing external installation space by placing the booster tank partially or fully inside the tub.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the booster tank is mounted outside the footprint or on top of the dishwashing machine, then the heat loss to ambient air is reduced, but the device occupies additional floor space and complicates service access
Solution Approach 1:
The booster tank is nested within the dishwashing machine's tub structure, utilizing the existing internal space. The tank is positioned inside the tub where it can heat water without occupying additional floor space, while still achieving reduced heat loss compared to external mounting configurations.
Solution Approach 2:
The booster tank is oriented vertically within the tub, utilizing the vertical dimension rather than horizontal floor space. This dimensional repositioning allows the tank to be integrated within the machine's footprint while maintaining effective heating functionality.
2Loss of energy
If the booster tank is mounted outside the footprint, then heat loss to ambient air is minimized, but service access becomes more difficult due to multiple locations
Solution Approach 1:
The booster tank is merged with the dishwashing machine's tub structure, consolidating what would be separate service locations into a single integrated unit. This integration maintains reduced heat loss while improving service accessibility by allowing technicians to access all components from one location.
3Area of stationary object
If the booster tank is placed inside the tub, then space requirements are minimized, but heat transfer efficiency to ambient air is reduced
Solution Approach 1:
The patent converts the potential harm of reduced heat loss (which could be seen as insufficient heating capability) into a benefit by utilizing the contained heat more efficiently for water heating. The insulated environment within the tub becomes advantageous for maintaining water temperature and improving overall 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
This design enhances energy transfer to the wash water, reducing energy consumption, minimizing space requirements, and simplifying service access by integrating the booster tank with the dishwashing machine's tub, thereby improving operational efficiency and reducing the footprint of the machine.
Implementation Method 1
The booster tank is connectable to an interior of a tub of a dishwashing machine to transfer heat from the booster tank to the liquid within the tub
Implementation Method 2
heat from the booster tank and water therein is radiated to ambient air and lost from the system

AI summary
A dishwashing machine includes a tub having an interior that holds a first liquid and a booster tank that includes a housing and at least one heater disposed within the housing. The booster tank is at least partially disposed within the interior of the tub such that at least a portion of the booster tank is at least partially submerged within the first liquid, whereby the first liquid is heated by the booster tank. A dishwashing machine includes a tub containing a liquid therein and a wash pump assembly that includes a pump housing; an inlet in the pump housing; an outlet in the pump housing; and a pump having a motor that pumps the liquid from the tub through the pump housing via the inlet to a device that sprays the liquid within a dishwasher via the outlet. The liquid is heated by means of a heater which is disposed either in proximity to the inlet, in proximity to the outlet, and/or in the spray device before the liquid is pumped out of the spray device.
