Solution Overview
Problem
Existing vacuum cleaners face issues with heat management, where the heat from the steam generator can damage sensitive electronic components, cause overheating of the pump, and pose a risk of burns to the user, due to the lack of proper ventilation and placement of the heater and bucket within the main body.
Innovation Solution
A cleaner design featuring a cleaning module with an air inlet and air outlet configuration that directs airflow to cool internal components, including a mop motor and PCB, while a shielding member prevents steam from entering the suction port, and partition walls manage heat around the heater to enhance thermal efficiency and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the heater and bucket are installed in the main body to maximize portability and simplify structure, then the device complexity is reduced, but the heat from the heater damages sensitive electronic components and causes overheating of the pump
Solution Approach 1:
The device is divided into two separate modules: a main body housing electronic components and a cleaning module housing the heater and bucket. This segmentation isolates heat-generating components from sensitive electronics, resolving the contradiction between structural simplicity and heat damage prevention.
Solution Approach 2:
A heat dissipation structure with air inlet and outlet channels is introduced as an intermediary between the heater and the main body. This intermediary structure manages heat flow, allowing it to escape away from electronic components while maintaining the integrated module design.
2Length of moving object
If the heater is placed within the main body to reduce overall device size, then the length of the device is reduced, but the heat causes overheating of the pump and damage to electronic equipment
Solution Approach 1:
The device is divided into a main body and a detachable cleaning module. The heater is placed in the cleaning module, separating it from the pump and electronic equipment in the main body. This maintains a compact overall length while preventing heat transfer to sensitive components.
Solution Approach 2:
The heater and bucket are extracted from the main body and placed in a separate cleaning module. This extraction removes the heat source from proximity to the pump and electronics, solving the overheating problem while keeping the device compact through modular design.
3Ease of operation
If the cleaning module is designed as an integrated unit with the main body, then the ease of operation is improved, but the heat from the heater poses a risk of burns to the user
Solution Approach 1:
The cleaning module is segmented as a detachable unit from the main body. This allows the heater to be isolated in the cleaning module, preventing direct contact with users while maintaining ease of operation through simple attachment and detachment of the module.
Solution Approach 2:
A heat dissipation structure with air channels is introduced as an intermediary between the heater and the external environment. This intermediary guides heat away from user-contact surfaces, reducing burn risk while preserving the integrated operational design.
4Productivity
If the heater is positioned to maximize steam generation efficiency, then the productivity is improved, but the heat radiated from the heater damages sensitive electronic equipment
Solution Approach 1:
The device is segmented into a main body with electronics and a cleaning module with the heater. This segmentation allows the heater to be positioned optimally for steam generation within the cleaning module while physically isolating it from electronic equipment in the main body.
Solution Approach 2:
A heat dissipation structure with air inlet and outlet channels is introduced as an intermediary. This structure manages heat flow from the heater, directing it away from electronic components while maintaining the heater's optimal positioning for efficient steam generation.

AI summary
The present disclosure relates to a cleaner including a cleaning module which cleans a cleaning area by generating steam. The cleaning module includes: a cleaning module housing which is connected to the main body, forms an appearance, and forms a space therein; a heater which is disposed within the cleaning module housing and generates steam from water; an air inlet which is formed on one side of the cleaning module housing and into which external air is introduced; and an air outlet which is formed on the cleaning module housing, is disposed above the air inlet, and through which the air in an internal space of the cleaning module is discharged to the outside. As a result, electronic equipment disposed around the heater can be prevented from being damaged by the heat emitted from the heater.
