Mat Cleaning Device Using Vacuum-Pump Hot Air for Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mat cleaning devices for vehicles only wash mats but do not dry them, leading to moisture evaporation issues and high energy costs when using heating devices for drying.
Innovation Solution
A mat cleaning device that uses hot air from a vacuum pump to dry mats, eliminating the need for a separate heating device and incorporating a first pressing roller with friction members to efficiently discharge the mat's end part during suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heating device is used to dry the mat, then the drying function is improved, but the energy consumption and operational cost increase
Solution Approach 1:
The vacuum pump serves dual functions: removing moisture from the mat surface and providing hot air for drying. By utilizing the vacuum pump's discharged air (which is naturally heated due to compression and friction) for drying purposes, the system eliminates the need for a separate heating device, thereby reducing energy consumption while maintaining effective drying capability
Solution Approach 2:
The system uses its own operational byproduct (hot air discharged from the vacuum pump) to perform the drying function. The vacuum pump's compression process naturally heats the air, and this heated air is redirected to dry the mat, making the system self-sufficient and eliminating external energy requirements
2Reliability
If the mat is suctioned by the vacuum suction means, then moisture removal is improved, but the end part of the mat becomes stuck and discharge efficiency decreases
Solution Approach 1:
Friction members are selectively attached only to specific portions of the pressing roller that contact the mat's end part. This localized application of friction material allows the roller to grip and discharge the mat end effectively without interfering with the vacuum suction's moisture removal function on the rest of the mat surface
Solution Approach 2:
The pressing roller is divided into different functional zones: portions with friction members for gripping and discharging the mat end, and portions without friction members that allow smooth passage and vacuum suction. This segmentation enables the roller to perform multiple functions at different locations along its surface

Implementation Method 1
a vacuum pump which forms vacuum pressure; a vacuum suction means which sucks moisture and foreign matter on a surface of a washed mat by using the vacuum pressure formed by the vacuum pump
Implementation Method 2
a centrifugation chamber which provides the vacuum pressure formed by the vacuum pump to the vacuum suction means and centrifuges the moisture and foreign matter sucked by the vacuum suction means
Implementation Method 3
dries a washed mat by using hot air discharged from a vacuum pump provided to remove moisture of the washed mat
