Description

Plasma electric refrigerator

The utility model relates to a kind of refrigerator, especially relates to a kind of refrigerator with refrigerating chamber.

Under the underdeveloped situation in market, people wish to buy the refrigerator of the big capacity refrigerating chamber with deep layer freezing function, be used for the food that granting of long time stored unit or market are purchased, the refrigerating chamber of refrigerator, refrigerating chamber volume are mostly at the 100-200 liter, and cryogenic temperature reaches-18 ℃ to-24 ℃.Under this holding conditions,, also destroyed the freshness and the nutritional labeling of food widely though the food storage life has prolonged.Abundant and flourishing along with market, people's quality of life idea changes, because the implementation of two-day weekend, people are going market purchasing also as a kind of interesting stress-relieving activity, market no longer needs in the past, and the sort of big volume, deep cooling freeze, the refrigerator of long term storage food, and a kind of storage life of demand is long but can keep the refrigerator of the freshness and the nutritional labeling of food urgently.

The purpose of this utility model be according to market demand, a kind of plasma electric refrigerator that has only refrigerating chamber not have refrigerating chamber is provided, it can make food under the condition of not freezing, and preserves freshly, can keep the freshness and the nutrition of food to greatest extent.

The utility model is to realize its goal of the invention by following technical solution.Design a kind of plasma electric refrigerator, have refrigerating chamber, it also comprises the plasma generator that can import plasma in refrigerating chamber; Plasma generator is installed in the outside or inner of refrigerator.

In the such scheme, refrigerating chamber is divided into multilayer, and every layer is sealant.

In the such scheme, refrigerating chamber top is provided with the long wavelength ultraviolet fluorescent tube.

In the such scheme, external plasma electric refrigerator ionic medium body generator is made up of housing, plasma generation power supply, automatic control circuit board, plasma generation chamber, by-pass cock and air pump.

In the such scheme, built-in plasma electric refrigerator ionic medium body generator comprises: shell, plasma generation sheet and the printed board and the inner box that are provided with time, generating capacity control circuit; Printed board is sealed in the inner box; The output of described control circuit is connected with plasma generation sheet through inner box.

Plasma electric refrigerator of the present utility model has the following advantages:

1, turns cold to freeze and be refrigeration, keep the freshness and the nutritional labeling of food; This device has only refrigerating chamber, does not have refrigerating chamber, can make fresh fish, fresh meat under the condition of not freezing, and preserves 10 days freshly, and prepared food was preserved 10 days, and vegetables preserved 14 days, and fruit was preserved 20 to 90 days.

2, energy-conservation, power saving; Because plasma can improve the storage temperature of food, under-10 ℃ of conditions, can preserve one month as the flesh of fish, under-3 ℃ to 1 ℃ conditions, fresh fish meat can be preserved 10 days, and the fruits and vegetables storage temperature is 6 to 10 ℃, the prepared food storage temperature is 4 to 8 ℃, can make the power consumption of refrigerator save more than 50%.

3, leftover is not perishable; Plasma has obvious sterilization, disinfective action, can make leftover not perishable.

4, the refrigerator cost reduces; The deep cooling that plasma electric refrigerator has replaced original refrigerator freezes, and does not need overcritical storage temperature very low, can reduce the refrigeration requirement of the thickness requirement and the compressor of refrigerator heat-insulation layer, thereby can reduce the cost of refrigerator.

Below in conjunction with drawings and Examples, further specify the technical solution of the utility model.
