Detergent dispensing device and dish washer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergent dispensing devices in dishwashers occupy a large space and have limited storage capacity, which is inefficient in terms of space utilization and functionality.
Innovation Solution
A detergent dispensing device comprising a storage box with a discharge pump and a pipeline module, where the storage box is designed with a first half shell and a second half shell connected to form a storage cavity, and the discharge pump is configured to suck and dispense detergent, with a pipeline module including filling, inlet, and outlet channels for efficient detergent distribution, allowing for separate storage and dispensing of multiple detergents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the detergent dispensing device uses a traditional storage structure, then the storage space is sufficient, but the device occupies a large space and has poor space utilization
Solution Approach 1:
The discharge pump is nested within the storage cavity, with the pump body positioned inside the space defined by the first and second half shells. The pump accommodating space is formed by the second half shell, allowing the pump to occupy the same spatial envelope as the storage cavity, thereby reducing the overall device thickness while maintaining both storage capacity and pumping functionality.
Solution Approach 2:
The storage cavity and pump accommodating space are arranged in a layered configuration along the thickness direction. The first half shell forms the front wall, the second half shell forms the rear wall and defines the pump accommodating space, creating a three-dimensional arrangement that optimizes space utilization in the thickness dimension.
2Adaptability or versatility
If the detergent dispensing device stores multiple detergents separately, then the functionality is enhanced, but the device complexity increases
Solution Approach 1:
The storage cavity is divided into multiple storage spaces using partition walls, with each space dedicated to storing a specific type of detergent. Correspondingly, the pipeline module is segmented into multiple independent channels, with each channel connected to a specific storage space and equipped with its own discharge pump or pump control mechanism, enabling independent dispensing of different detergents.
Solution Approach 2:
The discharge pump is designed with multi-functionality to handle different types of detergents. The pump can be configured to draw from different storage spaces through the pipeline module, and the system can adaptively control the pump to dispense appropriate detergent types based on detected dishware dirtiness levels, making the system versatile for multiple detergent applications.
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
The solution reduces the thickness of the detergent dispensing device, improves space utilization, and enables accurate and efficient dispensing of multiple detergents, enhancing the overall efficiency and functionality of the dishwasher.
Implementation Method 1
The discharge pump is configured to suck the detergent from the storage cavity and to dispense the detergent to the outside of the detergent dispensing device
