Abstract

Provided is a multi-purpose conservation apparatus. The multi-purpose conservation apparatus includes a storage case, a light source module disposed in the storage case and configured to selectively remove a harmful gas in the storage case, and a control unit configured to control intensity of radiation of the light source module according to internal environmental data of the storage case. Accordingly, the intensity of radiation of the light source module can be adjusted according to the internal environmental data of the storage case, efficiently adjusting a level of photocatalysis.

First claim

The invention claimed is:

1. A multi-purpose conservation apparatus comprising:
a storage case comprising an inner case having an accommodating unit formed in the inner case and including an open surface, and an outer case spaced apart from an outer circumferential surface of the inner case and surrounding the outer circumferential surface of the inner case;
a light source module disposed in the storage case and comprising a photocatalyst layer and configured to selectively remove a gas harmful to an article stored in the storage case and at least one light emitting diode configured to radiate light to a surface of the photocatalyst layer to activate the photocatalyst layer; and
a control unit communicatively linked with the light source module and configured to control intensity of radiation of the light source module based at least partly on internal environmental data of the storage case,
wherein the light emitting diode is disposed in a space section between the inner case and the outer case,
the photocatalyst layer is coated on at least one of an inner circumferential surface of the inner case,
the inner case includes a material that allows light from the light emitting diode to pass through the inner case, and
the accommodating unit and the space section are separated by the inner case so that the accommodating unit stores a product including a fluid.

2. The multi-purpose conservation apparatus according to claim 1 , wherein the storage case further comprises:
a cover unit coupled to the accommodating unit and having a space inside of the cover unit.

3. The multi-purpose conservation apparatus according to claim 2 , wherein the light emitting diode is disposed in the space of the cover unit, and
the photocatalyst layer is coated on one surface of the cover unit facing to the accommodating unit.

4. The multi-purpose conservation apparatus according to claim 1 , wherein the light emitting diode radiates light having a wavelength of 200 nm to 400 nm.

5. The multi-purpose conservation apparatus according to claim 1 , wherein the article includes fruits or vegetables, and the gas harmful to the fruits or vegetables is generated from fruits or vegetables.

6. The multi-purpose conservation apparatus according to claim 5 , wherein the gas harmful to the fruits or vegetables comprises ethylene gas.

7. The multi-purpose conservation apparatus according to claim 1 , wherein the internal environmental data comprises at least one of information on an amount of fruits or vegetables, information on opening or closing of the storage case, or information an amount of the gas harmful to the article.

8. The multi-purpose conservation apparatus according to claim 1 , further comprising a display unit configured to display data received from the control unit.

9. The multi-purpose conservation apparatus according to claim 1 , wherein the light source module includes two or more light emitting diodes arranged in a pattern to evenly irradiate the surface of the photocatalyst layer to activate the photocatalyst layer.

10. The multi-purpose conservation apparatus according to claim 1 , wherein, in addition to the at least one light emitting diode, the light source module further includes additional light emitting diodes arranged along with the at least one light emitting diode in a pattern, wherein the additional light emitting diodes and the at least one light emitting diode in the pattern are configured to radiate light on the surface of the photocatalyst layer to activate the photocatalyst layer and decompose the gas harmful to the article.

11. The multi-purpose conservation apparatus according to claim 1 , wherein a thickness of the photocatalyst layer is 10 μm to 30 μm.

12. The multi-purpose conservation apparatus according to claim 1 , wherein the photocatalyst layer is coated on entire inner circumferential surface of the inner case.

13. The multi-purpose conservation apparatus according to claim 1 , comprising:
an absorbent disposed on the photocatalyst layer to absorb a smell causing material.

14. The multi-purpose conservation apparatus according to claim 13 , wherein the absorbent includes activated carbon, supported metal activated carbon, potassium permanganate (KMnO 4 ), or Zeolite.

15. The multi-purpose conservation apparatus according to claim 1 , wherein the internal environmental data comprises information on a lighting quantity or on/off switching time of the light source module.

16. The multi-purpose conservation apparatus according to claim 1 , comprising:
at least one sensor unit disposed in the storage case.

17. The multi-purpose conservation apparatus according to claim 16 , wherein the sensor unit includes a gas sensor or a flow rate sensor to measure an amount of the gas harmful to the article.

18. The multi-purpose conservation apparatus according to claim 1 , wherein the control unit is physically separated from the storage case and is communicatively linked with the storage case using a wireless communication medium.

19. The multi-purpose conservation apparatus according to claim 16 , wherein the at least one sensor unit includes a height sensor and a pressure sensor to monitor a height and weight of the article stored in the storage case.
