Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pellet grills have limited functionality, with inefficient heat distribution and complex ash removal processes, making them unsuitable for diverse cooking needs and inconvenient to use.
Innovation Solution
A pellet grill design featuring a fire-proof partition plate with a fire-pervious window and an ash removal mechanism, allowing for independent temperature control and easy ash removal without external tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the internal space of the grill body is made large to distribute heat uniformly, then heat distribution is improved, but the cooking efficiency deteriorates and the temperature cannot be effectively increased
Solution Approach 1:
The grill body is divided into two independent cavities (upper and lower) by a fire-proof partition plate. The lower cavity contains the burning chamber for heat generation, while the upper cavity contains the wire grid for cooking. This segmentation allows independent temperature control in each cavity, enabling both uniform heat distribution and high-temperature cooking capabilities.
Solution Approach 2:
A fire-pervious window with opening and closing device is arranged on the fire-proof partition plate. By dynamically opening or closing this window, the system can switch between different operating modes: opening for high-temperature roasting (improving cooking efficiency) and closing for low-temperature smoking (maintaining uniform heat distribution).
2Ease of operation
If the wire grid is made detachable to allow ash removal, then ash removal becomes possible, but the operation complexity increases and time is consumed
Solution Approach 1:
The ash removal mechanism is extracted as a separate functional component from the wire grid assembly. An ash falling port is formed in the bottom of the lower cavity, and an ash collection box can be detached from the grill body. This allows ash to be removed directly from the burning chamber without needing to disassemble the wire grid, simplifying the operation while maintaining ash removal capability.
Solution Approach 2:
The ash collection box is designed to be detachably mounted below the grill body, allowing users to easily remove and empty the collected ash without requiring additional tools or complex procedures. The system serves itself by collecting ash in a readily accessible location.
Applied Scientific Principles
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 both high-temperature roasting and low-temperature smoking functions, improving cooking efficiency and simplifying ash removal, thus enhancing user convenience and versatility.
Implementation Method 1
a fire-pervious window is arranged on the fire-proof partition plate and is located above the burning chamber
Implementation Method 2
pellets to be burnt are fed into the burning chamber via the feed inlet and are burnt in the burning chamber to generate heat
Implementation Method 3
an ash removal mechanism for removing ash accumulated in the burning chamber is arranged on the grill body

AI summary
A pellet grill includes a grill body, a burning chamber and a wire grid arranged in the grill body. The wire grid is arranged above the burning chamber. A pellet inlet is formed in a lateral portion of the grill body. A fire-proof partition plate is arranged between the wire grid and the burning chamber and partitions the grill body into an upper cavity and a lower cavity. The burning chamber is arranged in the lower cavity. The wire grid is arranged above the upper cavity. A fire-pervious window is arranged on the fire-proof partition plate and is located above the burning chamber. An opening and closing device for controlling the fire-pervious window to be opened to realize higher temperature or closed to realize lower temperature is arranged on the fire-pervious window. An ash removal mechanism for removing ash accumulated in the burning chamber is arranged on the grill body.
