Solution Overview
Problem
Existing water supply apparatuses face challenges in cleaning the cooling tank, as the evaporator is often integrated within, making maintenance inconvenient and the refrigeration effect suboptimal when a detachable cooling tank is used.
Innovation Solution
The water supply apparatus features a heat exchange device positioned outside the cooling tank, allowing water to perform heat exchange with the evaporator, facilitating easy cleaning and enhancing the cooling effect by separating the evaporator from the cooling tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the evaporator is arranged on the inner or exospore of the cooling tank, then the refrigeration effect is achieved, but cleaning the cooling tank becomes inconvenient
Solution Approach 1:
The patent divides the cooling system into separate components: the cooling tank and the heat exchange device (containing the evaporator). By segmenting the evaporator from the cooling tank and placing it in a separate heat exchange device, the patent enables easy cleaning of the cooling tank while maintaining refrigeration functionality through the external heat exchange device.
Solution Approach 2:
The evaporator is extracted from the cooling tank and placed in a separate heat exchange device. This extraction allows the cooling tank to be independently cleaned without the evaporator, solving the cleaning convenience problem while the heat exchange device continues to provide refrigeration effect through external heat exchange.
2Ease of operation
If the evaporator is arranged on the periphery of a detachable cooling tank, then cleaning becomes convenient, but the refrigeration effect is not distinct
Solution Approach 1:
The patent introduces a heat exchange device as an intermediary component between the cooling tank and the evaporator. This intermediary allows the evaporator to be positioned externally while still effectively cooling the water in the cooling tank through controlled heat exchange, thus maintaining distinct refrigeration effect while enabling convenient cleaning.
3Device complexity
If the evaporator is integrated within the cooling tank, then the structure is compact, but maintenance and cleaning become difficult
Solution Approach 1:
The patent segments the evaporator from the cooling tank by placing it in a separate heat exchange device. This segmentation maintains structural efficiency while significantly improving maintainability, as the evaporator can now be accessed, removed, and cleaned independently from the cooling tank without disassembling the entire system.
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
This configuration enables convenient cleaning of the cooling tank while improving the refrigeration performance by allowing for effective heat exchange outside the tank, resulting in a more efficient cooling process.
Implementation Method 1
the water in the cooling tank performs a heat exchange with the evaporator
Implementation Method 2
the water in the cooling tank performs a heat exchange with the evaporator
