Dishwasher Condensing Duct With Ridge for Internal Vapor Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashers expel hot, moist vapor during the drying cycle, causing burns, discomfort, corrosion, and slipping hazards, as they directly vent vapor into the room.
Innovation Solution
A condensing apparatus with a blower, air duct, and condenser fan that suctions vapor from the tub, circulates it through a vapor passage with a ridge to condense water, and returns de-moisturized air inside the dishwasher, preventing external expulsion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hot, moist vapor is directly vented outward from the dish washer through a steam vent, then the drying function is achieved, but burns and discomfort to persons near the dish washer occur
Solution Approach 1:
An air duct is introduced as an intermediary component between the vapor source and the external environment. The air duct channels the hot, moist vapor away from direct contact with persons near the dish washer, thereby maintaining the drying function while eliminating the harmful effect of burns and discomfort.
2Productivity
If hot, moist vapor is expelled outward from the dish washer, then the drying function is achieved, but corrosion and deformation of wallpaper and wood inside the room occur
Solution Approach 1:
The air duct serves as a mediator that redirects the vapor flow path. Instead of allowing vapor to contact and damage wallpaper and wood surfaces, the air duct channels the vapor through a controlled pathway that prevents direct interaction with vulnerable materials, thus preserving the drying effectiveness while preventing corrosion and deformation.
3Productivity
If hot, moist vapor is expelled outward from the dish washer, then the drying function is achieved, but condensed water collects on the floor causing slipping hazards
Solution Approach 1:
The air duct acts as an intermediary that controls the condensation process. By channeling the vapor through the air duct, the system manages where and how condensation occurs, preventing condensed water from directly reaching the floor and creating slipping hazards, while still achieving the drying function.
4Productivity
If a separate condenser fan is installed to blow air towards the air duct, then vapor condensation speed increases, but device complexity increases
Solution Approach 1:
The motor is designed to perform multiple functions: it drives both the dryer fan for vapor suction and the condenser fan for air blowing towards the air duct. This multi-functionality approach increases condensation speed while avoiding the need for separate motors, thereby limiting the increase in device complexity.
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
Effectively condenses vapor within the dishwasher, preventing external burns, damage to objects, and slipping hazards, while increasing operational efficiency with a common motor driving the fans.
Implementation Method 1
a condenser fan for blowing air at the air duct to exchange heat with the vapor circulating inside the vapor passage
Implementation Method 2
a vapor passage formed in the air duct for circulating the vapor suctioned from inside the tub and generating condensed water

AI summary
A condensing apparatus of a dish washer is provided. The condensing apparatus includes a blower and an air duct. The blower suctions vapor from inside a tub of the dish washer. The air duct is connected to the blower, and has a vapor passage formed therein through which the vapor flows and in which condensed water is formed. The vapor passage has a ridge formed thereon to stop the condensed water.
