AI Technical Summary
Current refrigerators generally have poor odor removal performance. How can we improve the odor removal effect without increasing costs?
The system employs a deodorizing module, which includes a filter, a UVC-PCBA board, and a photocatalyst block. Polluted gas first passes through the filter to remove large particles, then the UVC-PCBA board activates the photocatalyst block to generate hydroxyl radicals and superoxide radicals, which decompose odor molecules and bacteria, and finally the gas is discharged through the air outlet.
It achieves efficient decomposition of odor molecules and bacteria, purifies the air, has a compact structure and low cost, and has a good odor-removing effect.

Abstract
Claims
1. A taste-free module, characterized in that: The odor-eliminating module includes a hollow lower cover forming a cavity and an upper cover snapped together with the lower cover. A filter, a UVC-PCBA board, and a photocatalyst block are sequentially arranged in the cavity within the lower cover along the air outlet direction. An air inlet and an air outlet are respectively provided on two parallel sides of the lower cover. The polluted gas enters the cavity within the lower cover through the air inlet, passes through the filter and the photocatalyst block in sequence, and is then discharged through the air outlet. The UVC-PCBA board has a UV lamp bead on the side facing the photocatalyst block; the photocatalyst block is made of honeycomb ceramic surface loaded with nanoscale photocatalyst material.
2. The taste-free module according to claim 1, characterized in that: The upper cover of the outer shell is tightly fitted with the lower cover of the outer shell, the top surface of the UVC-PCBA board, and the top surface of the filter screen; the upper cover of the outer shell is provided with a hook that snaps onto the lower cover of the outer shell; the upper cover of the outer shell is fixedly connected to the top plate of the UVC-PCBA board on the UVC-PCBA board with screws. The upper cover of the outer shell is provided with a U-shaped protrusion located on the bottom surface of the upper cover of the outer shell. The U-shaped protrusion is arranged around the top surface of the photocatalyst block, and the photocatalyst block and the U-shaped protrusion are either transitionally fitted or interference-fitted. The upper cover of the outer shell is provided with a threaded hole that is threaded to the lower cover of the outer shell.
3. The taste-free module according to claim 1, wherein: The lower cover of the outer casing is provided with a filter support for fixing the filter screen; the lower cover of the outer casing is provided with a UVC-PCBA fixing groove for the lower part of the UVC-PCBA board to be embedded, the entrance of the UVC-PCBA fixing groove is provided with an oblique guide angle, and the UVC-PCBA board and the UVC-PCBA fixing groove are interference fit.
4. The taste-free module according to claim 3, characterized in that: The lower cover of the outer casing is provided with a U-shaped cable outlet located on the short side of the lower cover. The wires connected to the UVC-PCBA board pass through the U-shaped cable outlet. The wires are soldered to the UVC-PCBA board, and a cable tie is provided at the end of the wires connected to the UVC-PCBA board to bind the wires. A terminal block for connecting to the power supply is provided at the end of the wires away from the UVC-PCBA board. An L-shaped boss supporting the UVC--PCBA board is provided on the lower cover of the outer casing near the U-shaped cable outlet.
5. The taste-free module of claim 1, wherein: The lower cover of the outer shell is provided with a T-shaped partition located on the inner wall of the bottom of the receiving cavity. The T-shaped partition divides the receiving cavity into a first part and a second part. The filter and the UVC-PCBA board are located in the first part, and the photocatalyst block is located in the second part. The bottom surface of the second part is lower than the bottom surface of the first part and forms a step. The lower cover of the outer shell is provided with a U-shaped slot that snaps into the upper cover of the outer shell.
6. The taste-free module of claim 1, wherein: The filter screen is made of 304 / 316L food-grade stainless steel wire woven or polypropylene meltblown nonwoven fabric, and the cross-sectional area of the filter screen is equal to the cross-sectional area of the receiving cavity at the position where the filter screen mates with the lower cover of the outer shell.
7. The taste-free module of claim 1, wherein: The UVC-PCBA board is equipped with ultraviolet lamp beads facing the photocatalyst block.
8. The taste-free module of claim 1, wherein: The photocatalyst block is made of a honeycomb ceramic surface loaded with a nanoscale photocatalyst material, which is titanium dioxide (TiO2).
9. The taste-free module of claim 1, wherein: At least two photocatalyst blocks are arranged in the lower cover of the shell, and the photocatalyst blocks are discontinuous with adjacent photocatalyst blocks.
