Abstract

The utility model relates to an electronic freshness-keeping sterilizer for refrigerator, comprising a gate-controlling switch, an intermission controller, a high-frequency circuit, a high-voltage circuit, an anion generator, a gate-alarming circuit, etc. The utility model has the obvious effect of freshness-keeping, and the concentration of the anions and the running period can be regulated according to the quantity of the food inside the refrigerator.

Description

Freshness-keeping device of refrigerator with electronic sterilizer

The utility model relates to the fresh-keeping device of a kind of electronic sterilizing, the fresh-keeping device of particularly a kind of refrigerator electronic sterilizing.

At present, the refrigerator of the being sold food storage time that exists that all degree is different one is long on the market, food can produce problems such as peculiar smell, fruits and vegetables rot in the refrigerator, people use various chemical deodorizing agent, cleaning agent etc. for this reason, but it exists problems such as the resistance to the action of a drug and residual hazard, and be disposable use, effect can not be lasting, and is also uneconomical.A kind of " strengthening the method and the equipment thereof of fruit, fresh-keeping of vegetables effect with ozone ion " this equipment that discloses among the patent document CN86101706 is applicable to that storage in enormous quantities such as the fruits and vegetables place of production, warehouse is fresh-keeping, and volume is big, cost is high, should not make the refrigerator food fresh-keeping and use.

For overcoming above-mentioned deficiency, the purpose of this utility model is a kind of good refreshing effect of design, and it is low consume energy, the fresh-keeping device of refrigerator electronic sterilizing that volume is little, dependable performance and life-span are grown.

For achieving the above object, the utility model has adopted following structure to form: gate controlled switch, intermittent controller, high-frequency circuit, high-tension circuit, anion generator and police guard at as entrance's telegraph circuit, wherein intermittent controller is to be hindered with the charge-discharge circuit that electric capacity constitutes by time base circuit and resistance; High-frequency circuit is made up of the peripheral circuit that time base circuit and resistance and electric capacity constitute; High-tension circuit is made up of high voltage package and triode, is connected with a switch on the primary coil of high voltage package, recently realizes control to high pressure to regulate the elementary and secondary number of turn, thereby realizes the control to negative ion concentration.

The utility model is through experiment, in refrigerator, put into rotten food, free from extraneous odour produces and rotten place generation atrophy, and fresh-keeping effect is obvious, and this project organization is simple, volume is little, power consumption low (≤4 watts) also can be according to the concentration of how much regulating anion and the service cycle of food in the refrigerator, and complete machine is furnished with close the door prompting warning and work control indication, safe and reliable, can use for a long time.

Below in conjunction with accompanying drawing the present invention is done to describe further:

Fig. 1 is the fresh-keeping device schematic block diagram of refrigerator electronic sterilizing.

Fig. 2 is the fresh-keeping device circuit structure diagram of refrigerator electronic sterilizing.

Fig. 3 is the fresh-keeping device assembly structure of a refrigerator electronic sterilizing schematic diagram.

As shown in Figure 1, the utility model is made up of gate controlled switch (1), intermittent controller (3), high-frequency circuit (4), high-tension circuit (5), anion generator (6) and police guard at as entrance's telegraph circuit (2), as shown in Figure 2, said intermittent controller is to be hindered with the charge-discharge circuit that electric capacity (15) constitutes by time base circuit (16) and resistance (12), (13), (14); Said high-frequency circuit is made up of with the peripheral circuit that electric capacity (20), (21) constitute time base circuit (17) and resistance (18), (19); Said high-tension circuit is to be made of high voltage package (23) and triode (22), is connected to a switch (24) on the primary coil of high voltage package (23).

During work, when refrigerator doors is opened (or Men Wei closes tight), gate controlled switch (1) is in the A position, this moment, charging made triode (9), (10) conducting to electric capacity (8) by resistance (7), voltage is added on police guard at as entrance's telegraph circuit (2), gives the alarm, and prompting is closed the door.After refrigerator doors was closed tight, switch (1) was in the B position, and police guard at as entrance's telegraph circuit is cut off automatically, and inserted the main body circuit.Intermittent controller (3) is after power supply is switched on, the input 6 of time base circuit (16) is a low level, output 3 is a high level, triode (11) conducting, electric current is by triode (11), resistance (12), (13) electric capacity (15) is charged, going up voltage when electric capacity (15) is charged to when enough high, the input 6 of time base circuit (16) also is in high level, time base circuit (16) counter-rotating, its output 3 is a low level, triode (11) ends, and electric capacity (15) is by resistance (14), (12), (13) discharge over the ground is when being put into certain value, time base circuit input 6 is in low level, time base circuit (16) counter-rotating, its output 3 becomes high level, then so repeats above-mentioned charge and discharge process.When phase inverter (16) output is high level, red led (25) is bright, time base circuit (17) work, time base circuit (17) constitutes high-frequency circuit with peripheral cell, output 3 by time base circuit (17) is added to high-tension circuit, at this moment, triode (22) conducting, high-tension circuit (5) is by anion generator (6) discharge generation ozone; When basic at that time circuit (16) output was low level, green indicating lamp (26) was bright, and time base circuit (17) quits work, and triode (22) is by the high-tension circuit no-output, and generator (6) stops discharge, and ozone free produces.

Resistance (12) can be made of potentiometer, regulates the resistance of resistance (12), can change the charging interval.

On the primary coil of high voltage package (23), be connected to a switch (24), in order to changing the elementary turn ratio with secondary coil of high voltage package, realize control, thereby realized control ozone concentration to high pressure with this.

During installation, as shown in Figure 3, circuit part is packed in the shell (27), can put into the refrigerator back bottom, packing in the shell (28) in the display part, can put into the preceding base angle of refrigerator, and anion generator (6) is placed on refrigerator inside, connects with lead between three parts.
