Compact refrigerator for cosmetics

A compact refrigerator having a chamber for storing virtually preservative-free cosmetic preparations, said chamber including a top portion, a sidewall portion, and a bottom portion, said compact refrigerator comprising:

• a cooling device provided in said sidewall portion;
• a cooling plate located inside said sidewall portion and contacting said cooling device;
• a heat dissipating plate located outside said cooling device said heat dissipating plate have a natural heat dissipation capacity of Q.sub.0 cal/sec;
• a fan for promoting dissipation of heat by said heat dissipating plate;
• a cover forming said top portion wherein when said cover is opened, a maximum heat quality of Q.sub.1 cal/sec enters said compact refrigerator, wherein Q.sub.1 =Q.sub.0 ;
• a temperature sensor for detecting a temperature of said chamber;
• and
• control means for controlling said cooling device and/or said fan in response to an output signal of said temperature sensor by driving said fan only when greater than 2Q.sub.0 cal/sec are required in order to keep the temperature of said chamber and a temperature of the virtually preservative-free cosmetic preparations at a specific temperature or within a specific temperature range to prevent microbial contamination of the virtually preservative-free cosmetic preparations.

A method of optimizing storage of virtually preservative-free cosmetic preparations in a chamber, the chamber including a cover forming a top portion, a sidewall portion, and a bottom portion, wherein when said cover is opened, a maximum heat quality of Q.sub.1 cal/sec enters said compact refrigerator, wherein Q.sub.1 =Q.sub.0 said method comprising the steps of:

• (a) providing a cooling device in the sidewall portion;
• (b) locating a cooling plate inside the sidewall portion and contacting the cooling device;
• (c) locating a heat dissipating plate outside the cooling device said heat dissipating plate have a natural heat dissipation capacity of Q.sub.0 cal/sec;
• (d) providing a fan for promoting dissipation of heat from the heat dissipating plate;
• (e) detecting a temperature of the chamber with a temperature sensor;
• and
• (f) controlling the cooling device and/or the fan in response to temperature detected in said step (e) by driving said fan only when greater than 2Q.sub.0 cal/sec are required in order to keep the temperature of the chamber and a temperature of the virtually preservative-free cosmetic preparations at a specific temperature or within a specific temperature range to prevent microbial contamination and optimize the storage of the virtually preservative-free cosmetic preparations.
