Abstract

The utility model relates to a deodorising and fresh-keeping device for miniature ice cabinets and iceboxes, which is a deodorising device used for the ice cabinets and the iceboxes. The utility model is mainly composed of a glow tube mixed with inert gas, a pulse transformer, a thyristor intermediate frequency inverter, a capacitor, a rectifier, etc. The utility model has low power consumption and the consumed power is about 1.2w. The 180 kilolitre icebox can be effectively deodorized in 10 minutes, and has the fresh-keeping function for the stored food. The utility model has the advantages of low material cost, simple and reasonable structure and high reliability.

Description

Miniature ice cabinet, freezer deodorising and fresh-keeping device

This utility model provides is a kind of miniature refrigerator, the deodorant for refregerator fresh-keeping device of distinguishing the flavor of.

Present existing deodorant for refregerator device, generally all adopt the 50HZ civil power, and operating frequency is at 50HZ, the generating capacity of its ozone is subjected to the influence of operating frequency and can not improves, and noise coefficient is greater than the refrigerator noise of placing, and other adopts the ozone deodoriser of dry cell power supply, because it is low that its energy content of battery is imitated, the deodorizing effect that ozone takes place also is restricted, and the cost height, and its structure is referring to CN89211041.4.

The purpose of this utility model is the problem that overcomes above-mentioned existence, propose a kind of simple in structure, deodorizing effect is good, cost is low, is suitable for the fresh-keeping device of deodorize---refrigerator, refrigerator odour removing and fresh keeping device that refrigerator, refrigerator use.

Technical solution of the present utility model: miniature refrigerator, deodorant for refregerator distinguish the flavor of the built-in mixed inert gas glow tube 1 of fresh-keeping device in, external electrode is to join with secondary coil two ends of pulse transformer 2 respectively, the anode tap of controllable silicon CT in the primary coil of pulse transformer and the controllable silicon if inverter 3 joins, commutator 4, capacitor 5 is serially connected in power input A ', between the B, the controllable silicon anode in the controllable silicon if inverter 3 and the primary coil of transformator 2, resistance R 1, commutator 4 serial connections, the resistance R 2 between the silicon controlled control utmost point and power input two ends and the dividing point C of resistance R 3 join, and electric fuse 6 is located at power input B end.Secondly the transformator in the controllable silicon if inverter also can be connected between silicon controlled negative electrode and power input B, and resistance R 3 is serially connected between the silicon controlled control utmost point and negative electrode.Have in the controllable silicon if inverter again, also resistance R 2 can be serially connected in controllable silicon anode and silicon controlled control interpolar, resistance R 3 is serially connected between the silicon controlled control utmost point and silicon controlled negative electrode.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is circuit theory diagrams of the present utility model.

Accompanying drawing the 3, the 4th, two kinds of circuit theory diagrams of if inverter of the present utility model.

Operation principle: alternating current power supply is through rectification, filtering obtains DC voltage later on and supplies with if inverter, see that Fig. 2 works as power supply and charges to capacitor C 1 through current-limiting resistance R1, this moment, controllable silicon CT turn-offed, the voltage of charging capacitor rises, voltage on the divider resistance R3 rises thereupon, the silicon controlled trigger voltage rises, when this trigger voltage rises to trigger value, the controllable silicon conducting, voltage on the electric capacity is through the pulse transformator, the controllable silicon discharge, the electric current of this electric current and current-limiting resistance lumps together, primary coil through the pulse transformator, obtain high-voltage pulse on secondary, supply with the work of oxygen atom glow tube, controllable silicon is turn-offed by the back-emf that primary inductance produced of pulse transformer.Repeat the high-voltage pulse that above-mentioned state obtains certain frequency.If inverter also has two kinds of connections, and divider resistance is in parallel with controllable silicon, triggers to be connected with dividing point C, and pulse transformer is serially connected in the silicon controlled anode.Another kind is that pulse transformer is serially connected in negative electrode, sees Fig. 3, Fig. 4.Glow tube forms oxygen molecule ionization single oxygen atom under the highly compressed effect of intermediate frequency, and itself has that kinetic energy is very fast to combine generation ozone O3 with oxygen molecule, but the strong oxidizing property energy deodorize of ozone, and make food fresh keeping.
