The fruit refrigerator has a cold plate which is cooled by a thermal electric unit secured underneath. Power is supplied to the thermal electric unit and to a cooling fan which blows air over the thermal electric unit. The cold plate has a depressed center, and liquid drains down through a wick. The cold plate has a transparent cover. A circulating fan on the cold plate prevents stratification within the domed cover and helps equalize cooling of fruit on the tray.

What is claimed is: 1. A fruit refrigerator comprising: a body, a cold plate supported on said body, said cold plate having a top surface and a bottom surface, a cooling device directly connected to said bottom surface of said cold plate; a removable cover over said cold plate; a cooling fan in said body for moving cooling air over said cooling device to remove heat from said cooling device, a power supply connected to energize said cooling fan and said cooling device; a circulating fan adjacent said top surface of said cold plate to circulate air under said cover and only over said cold plate, said circulating fan being connected to said power supply so that when said cooling device is active, said circulating fan is energized to circulate air only above said cold plate. 2. The fruit refrigerator of claim 1 wherein said cold plate is dished to be lower in the center than adjacent its edges and said cooling device is attached to the bottom surface of said cold plate under said depressed center portion. 3. The fruit refrigerator of claim 2 wherein there is at least one hole through said cold plate in its depressed portion beside said cooling device so that condensation at said depressed center of said cold plate is strained through said cold plate. 4. The fruit refrigerator of claim 3 wherein there is a wick through said opening in said cold plate so as to wick moisture down through said cold plate, said wick being positioned in the flow of cooling air from said cooling fan and said cooling device. 5. The fruit refrigerator of claim 2 wherein said cooling device is a thermal electric cooling device, said thermal electric device having fins and said cooling fan blowing air across said fins. 6. The fruit refrigerator of claim 2 wherein said body has air inlet and air outlet holes therein and a divider through said body between said inlet and said outlet holes, said divider having an opening and said cooling fan being mounted at said opening. 7. The fruit refrigerator of claim 1 wherein said cover is a transparent cover. 8. The fruit refrigerator of claim 5 wherein there is a temperature sensor mounted on said circulating fan, said temperature sensor being connected to control said cooling device. 9. The fruit refrigerator of claim 8 wherein said power supply includes a control system connected to said temperature sensor and to said cooling device to actuate said cooling device when sensed temperature is above a set temperature. 10. The fruit refrigerator of claim 1 wherein said cold plate has a depressed center and said cooling device is mounted under said depressed center and said cold plate has at least one drain hole at its depressed center and there is a wick extending downward from said drain hole to drain moisture on said cold plate down into said body. 11. A fruit refrigerator comprising: a body, a cold plate supported on said body, said cold plate having a depressed center portion, an electrically powered cooler mounted on the underside of said cold plate under said center portion, a drain through said depressed center section away from said electrically powered cooler to drain water down through said drain opening away from the top of said cold plate; a circulating fan mounted above said cold plate, a transparent domed cover configured to fit over the top of said cold plate and enclose said circulating fan; a power supply connected to said electrically powered cooler so that said electrically powered cooler is energized to cool the space under said domed cover to a selected temperature and to energize said circulating fan to circulate air enclosed by said cover. 12. The fruit refrigerator of claim 11 wherein said electric cooler is a thermal electric cooler, said thermal electric cooler having cooling fins positioned within said body, a wick extending downwardly through said opening in said cold plate, a cooling fan within said body to circulate air into said body across said cooling fins and across said wick and out of said body. 13. The fruit refrigerator of claim 12 wherein said wick extends downward into said body from said drain hole, said wick being positioned in the air stream of said cooling fan. 14. The fruit refrigerator of claim 11 wherein said electric cooler is a thermal electric cooler and said power supply is in said body and is connected to said thermal electric cooler, said power supply providing appropriate voltage and current for said thermal electric cooler, a control system powered by said power supply, a sensor being connected to said control system and said circulating fan being connected to said control system to energize said cooler, said cooling fan and said circulating fan. 15. The fruit refrigerator of claim 11 wherein there is a speed selector switch mounted on said body to be accessible from the outside of body, said speed selector switch being connected to said circulating fan so that the amount of circulating air can be selected. 16. The fruit refrigerator of claim 12 wherein both said circulating fan and said temperature sensor are mounted in the same housing and said housing is mounted on the top of said cold plate. 17. The fruit refrigerator of claim 12 wherein said drain hole through said cold plate adjacent said thermal electric unit and said wick in said drain hole are positioned so that moisture on said tray is drained through said wick adjacent said fins on said thermal electric unit so that said cooling fan blows air over said wick. 18. The fruit refrigerator of claim 11 further including a temperature sensor, said temperature sensor being positioned to sense the temperature of air being circulated by said circulating fan and wherein said power supply includes a control system connected to said temperature sensor and to said electrically powered cooler to actuate said electrically powered cooler when sensed temperature is above a set temperature.
