Dual Heat-Tube Grill Valve Control for Even Gas Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grill stoves with multiple gas tubes cannot supply a fixed amount of gas stably, leading to uneven burning of ingredients.
Innovation Solution
A grill stove design featuring a grilling body with parallel first and second heat tubes, a valve unit, and a control valve that operates in three modes to control gas flow through different orifices, allowing for precise control of heat distribution for grilling varying amounts of ingredients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple gas tubes are arranged in conventional grill stoves, then heating capacity is increased, but gas supply stability deteriorates leading to uneven burning
Solution Approach 1:
The gas supply system is segmented into multiple independent control channels. Each heat tube (first heat tube, second heat tube) has its own control valve (first control valve, second control valve) that can independently regulate gas flow. This segmentation allows stable and precise control of gas supply to each heating element, eliminating the uneven burning problem while maintaining high heating capacity through multiple tubes.
2Ease of operation
If conventional control knobs are used for each gas tube, then ease of operation is maintained, but manufacturing precision of gas supply control deteriorates
Solution Approach 1:
The control mechanism uses rotatable control valves with adjustable opening degrees to precisely regulate gas flow parameters. Each control valve can be rotated to different positions, changing the gas flow rate parameter to match the heating requirements. This provides both ease of operation through simple rotation and precise control of gas supply parameters, resolving the contradiction between operational simplicity and control precision.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables consistent and controlled heat generation for grilling different quantities of ingredients, ensuring even cooking by adjusting the heat output through distinct operational modes.
Implementation Method 1
The control valve is rotated to stop the gas supply tube, to communicate with the gas supply tube via the first through orifice or to communicate with the gas supply tube via the second through orifice
Implementation Method 2
each grilling device includes a first heat tube and a second heat tube parallelly connected with the first heat tube

AI summary
A grill stove contains a grilling body and plural heating devices. Each grilling device includes a first heat tube, a second heat tube, an accommodation seat, and a valve unit. The accommodation seat has a first conduit, a second conduit, a gas supply tube, and a dispersion tube. The valve unit has a driving shaft and a control valve, the driving shaft extends out of the accommodation seat and is in connection with a first end of the control valve, and a second end of the valve unit inserts into the first conduit. The control valve has a channel, a first through orifice, a second through orifice, and a third through orifice. The control valve is rotated to stop the gas supply tube, to communicate with the gas supply tube via the first through orifice or to communicate with the gas supply tube via the second through orifice.
