Solution Overview

Problem

Pressurized ironing devices suffer from water accumulation in the evaporator, leading to safety hazards due to rapid heating and scalding water droplets when powered off.

Innovation Solution

An ironing device with a temperature sensor, control valve, and booster pump system that regulates water supply to the evaporator based on temperature, preventing water accumulation by stopping water flow when the evaporator is below a threshold temperature and using residual heat to evaporate remaining water.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the pressurized pipeline remains open continuously, then the device can operate随时, but water accumulates in the evaporator causing safety hazards

Engineering Contradiction:

Improvereadiness to operateVSAvoidwater accumulation and scalding risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary evaporation of residual water in the evaporator before allowing water supply to resume after power-off. The temperature sensor detects when the evaporator has been heated sufficiently to evaporate accumulated water, preventing scalding hazards when the device is restarted.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The temperature sensor continuously monitors the evaporator temperature and provides feedback to the control system. Based on this feedback, the control system automatically opens or closes the control valve to regulate water supply, ensuring water is only supplied when the evaporator temperature is above the threshold and no water accumulation will occur.

Inventive Principle:

Principle #23Feedback

2Productivity

If water is supplied continuously to the evaporator, then steam generation is sufficient, but water accumulates inside the evaporator

Engineering Contradiction:

Improvesteam generation capacityVSAvoidwater accumulation in evaporator

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The water supply to the evaporator is not continuous but periodic and conditional. The control valve opens only when the temperature sensor detects that the evaporator temperature is above the threshold value T, and closes when the temperature drops below T, creating a periodic supply pattern that matches the evaporation rate and prevents accumulation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system changes the operational parameters of water supply based on temperature conditions. When the evaporator temperature is below threshold T, water supply is stopped entirely. When temperature exceeds T, water supply is activated. This parameter-based control ensures water is supplied only when evaporation capacity is sufficient to handle the incoming water.

Inventive Principle:

Principle #35Parameter changes

3Speed

If the evaporator is heated rapidly after power-off, then the device can restart quickly, but accumulated water is heated and ejected as scalding droplets

Engineering Contradiction:

Improverestart speedVSAvoidscalding water droplets

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The system applies preliminary anti-action by heating the evaporator to a sufficient temperature before allowing water supply to resume. This preliminary heating action ensures that any water present in the evaporator will be immediately evaporated rather than accumulated and later ejected as scalding droplets, thus preventing the harmful effect before it can occur.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

The present invention discloses an ironing device, comprising: a water tank, an evaporator, a control valve and a booster pump. When a temperature sensor detects that a temperature of the evaporator is larger than or equal to a threshold value, the control valve opens, the booster pump starts to supply water from the water tank to the evaporator through a pipeline A, and the evaporator evaporates the liquid and sprays steam to iron clothing. When the temperature sensor detects that the temperature is less than the threshold value, the control valve shuts off the water supply from the water tank, the booster pump continues operating to supply the remaining water in a pipeline a to the evaporator, and then residual heat of the evaporator evaporates the remaining water in the pipeline a, thus to prevent the water from accumulating inside the evaporator.
