Solution Overview
Problem
Existing dual-cylinder washing machines face issues with excessive water vapor escaping during high-temperature steaming, which can damage household items and reduce visibility, and steam or foam can erode the fan due to improper channeling.
Innovation Solution
A dual-cylinder washing machine with a damper assembly in the air inflow pipe that blocks overflow during non-ventilation and allows airflow during ventilation, combined with a steam and foam overflow pipe, and a siphon pipe for water discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-temperature steaming is performed in dual-cylinder washing machine, then steaming and disinfection capability is improved, but excessive water vapor escapes causing damage to household items and reduced visibility
Solution Approach 1:
The patent introduces an intermediary substance (condensable vapor) and a condensation chamber that acts as a mediator between the steaming cylinder and the external environment. The vapor is condensed back to liquid water through heat exchange, preventing direct escape of steam while maintaining the steaming function. This resolves the contradiction by transforming the harmful vapor into a manageable liquid form.
Solution Approach 2:
The patent converts the harmful escaping vapor into a beneficial resource by condensing it back into liquid water that can be reused or safely discharged. The condensation process transforms the problematic steam into a useful byproduct, turning the harmful effect into a benefit while maintaining effective steaming and disinfection.
2Productivity
If steam is channeled through air duct assembly, then steam discharge is improved, but steam and foam erode the fan affecting service life
Solution Approach 1:
The patent segments the steam discharge path from the air duct assembly by introducing a separate condensation chamber and dedicated vapor discharge path. This segmentation prevents steam and foam from contacting the fan while maintaining effective steam discharge through the alternative path, resolving the contradiction between discharge efficiency and fan protection.
Solution Approach 2:
The patent extracts the harmful steam and foam components from the air duct system by routing them through a separate condensation chamber. This extraction removes the erosive elements before they can reach the fan, while the condensed liquid is discharged separately, maintaining steam discharge efficiency without compromising fan service life.
3Reliability
If heating temperature is increased for high-temperature steaming, then steaming effectiveness is improved, but water vapor generation increases causing more escape
Solution Approach 1:
The patent utilizes phase transition by condensing the high-temperature vapor back into liquid water through heat exchange in the condensation chamber. This phase change from gas to liquid reduces the volume and escape tendency of the vapor while maintaining the steaming effectiveness achieved through high-temperature heating, resolving the contradiction between steaming effectiveness and vapor generation quantity.

AI summary
A high-temperature boiling method, a computer-readable storage medium and a control device, which aim to solve the problem of excessive amounts of steam escaping when two washing tubes of an existing double-tube washing machine simultaneously perform high-temperature boiling for disinfection. By means of the high-temperature boiling method, when the temperature of washing water in a first washing tube (1) is extremely high and a large amount of steam is generated, a valve port corresponding to the first washing tube can be blocked by means of a three-way valve (3); and when the temperature of the washing water in the first washing tube (1) is reduced and an extremely small amount of steam or no steam is generated, a valve port corresponding to a second washing tube (2) in which the temperature of washing water continues to rise is blocked in time, thereby preventing, when the temperature of the washing water in the second washing tube (2) is extremely high and a large amount of steam is generated, the steam in the washing tube from escaping randomly. Therefore, the amount of escaping steam is effectively reduced when both washing tubes of a double-tube washing machine perform a high-temperature boiling procedure, thereby preventing adverse effects from occurring in a decorative environment and a visual environment of the house of a user caused by the amount of steam escaping from the double-tube washing machine.
