Description

The automatic deodorization and disinfection device of refrigerator

The utility model relates to the automatic deodorization and disinfection device of a kind of refrigerator.

Along with growth in the living standard, refrigerator has entered into huge numbers of families.It is fresh that refrigerator is preserved food as family, do not make in a short time rotten and indispensable household electrical appliance.Yet, present refrigerator is to adopt the reduction temperature to come food is carried out anti-corrosive fresh-keeping, the function that does not have sterilization, existence of bacterium and continuous breeding are multiplied, and with refrigerator in all cpds in the food, organic acid substance volatilizees and forms in a kind of refrigerator " off-odor ", makes food spoilage in the refrigerator.And existing refrigerator does not possess the deodorization and disinfection function is arranged, and existing de-odorised method generally is use the boxlike bad-smell adsorber, relies on suction flavor material of its inner dress, adopts the method for " adsorbing naturally " to come work, uses these methods, and effect is relatively poor.

The purpose of this utility model provides a kind of refrigerator efficiently automatic deodorization and disinfection device just at the problems referred to above.

Technical solutions of the utility model are finished like this.It is made up of ozonizer, ozonizer open circuit, be characterized in that the ozonizer open circuit is made up of current limliting voltage stabilizing, time-base circuit and instantaneous triggering circuit and high-pressure generating circuit, the power supply of ozonizer open circuit is imported an end and directly is connected with the 220V AC power, and the other end is to be connected with the 220V AC power by the temperature controller normal opened contact in the refrigerator circuit.

The utility model embodiment is described further in conjunction with the accompanying drawings.

Fig. 1 is the junction circuit figure of ozonizer open circuit and refrigerator circuit.

By shown in Figure 1, left side dotted line institute frame partly is a refrigerator circuit, the right side is the ozonizer open circuit, and ozonizer open circuit power input B directly is connected with the 220V AC power, and the other end is that the normal opened contact by the temperature controller Wk in the refrigerator circuit is connected with the 220V AC power.The ozonizer open circuit is made up of current limliting voltage stabilizing, time-base circuit, instantaneous triggering circuit and high-pressure generating circuit, and by shown in Figure 1, the current limliting mu balanced circuit is by capacitor C ₁, resistance R ₇Current-limiting circuit, diode D ₁～D ₄Bridge is put in order circuit, voltage stabilizing tube WD1, triode BG ₁The dilatation mu balanced circuit connect form.Time-base circuit is the integrated circuit (IC) of NE555 and the resistance R that is connected with its respective end pin by model ₁, R ₂,, capacitor C ₄, C ₅Form.By triode BG ₂, resistance R ₃, R ₄, R ₅, R ₆, capacitor C ₆, voltage stabilizing tube WD ₂And controllable silicon SCR ₁Form instantaneous triggering circuit.High-pressure generating circuit is by silicon controlled toggle SCR ₂And the diode D of the coupled reverse withstand voltage protection of do ₆, D ₇And divider resistance R ₈, R ₉, capacitor C ₇And step-up transformer B composition, transformer makes low pressure rise to the 3500V high pressure, and the two ends, limit of boosting are connected with ozonizer CH.

The principle of work of ozonizer open circuit is as follows: the alternating-current of 220V passes through C ₁And R ₇Current-limiting circuit is through D ₁～D ₄Rectification converts direct current to by alternating-current, by WD ₁, BG ₁The dilatation mu balanced circuit output of forming is for time-base circuit and instantaneous triggering circuit.

During each the energising, when promptly the temperature controller normal opened contact was closed, 3 pin of the NE555 of time-base circuit were in high level, and BG2 is in conducting state, and its collector electrode place is a lower level, makes controllable silicon SCR ₁End relay J ₁Not adhesive, its normally closed contact J ₁₁Still closed, high-pressure generating circuit is through relay J ₁Normally closed contact J ₁₁Be connected with the 220V AC power, the output high pressure makes ozonizer work, produces ozone O ₃Gas, time-base circuit make the upset of 3 pin be lower level, BG after the RC time-delay ₂Current collection is high level very, through C ₆Reach WD after the time-delay ₂Go out to wear voltage, trigger SCR ₁Conducting, J at this moment ₁Adhesive, its normally closed contact J ₁₁Disconnect, high-pressure generating circuit quits work because of outage, and ozonizer promptly stops to emit ozone, and the need of task are through the outage repetition of energising more again.

Because the power input A of ozonizer open circuit is connected with the normal opened contact of temperature controller Wk, thereby do not surpassing under the situation of refrigerator design temperature, the normal opened contact of Wk disconnects, thereby the ozonizer open circuit is not worked, when temperature is higher than design temperature in the refrigerator, the normal opened contact of thermo-relay RJ and Wk temperature controller is connected in the refrigerator circuit, freezer compressor running this moment, meanwhile, the work of ozonizer open circuit, high-pressure generating circuit work in it, ozonizer produces ozone refrigerator is carried out deodorization and disinfection, disconnects high-pressure generating circuit through the time-base circuit time-delay after several minutes, and ozonizer quits work, freezer compressor stops when arriving design temperature still in operation.Wk temperature controller normal opened contact restores and disconnects.Thereby whenever compressor during according to the design temperature starting operation, ozone is promptly emitted the ozonization deodorizing, quits work through time-delay then, and the break-make cycle operation reaches refrigerator disinfecting, deodorizing, sterilization, fresh-keeping purpose so repeatedly.

In addition, in circuit of the present utility model, as long as A, the B end of ozonizer open circuit is connected attaching plug, be exactly an independent product deodorant for refregerator sterilizer, during use, this deodorant for refregerator sterilizer is positioned over lattice on the refrigerator, pull out supply lead, the door that turns a refrigerator off inserts supply socket, start shooting after 3 minutes, take out then deodorizing end of power supply.This deodorant for refregerator sterilizer still can be to the deodorizing that carries out disinfection of ground such as toilet, dressing cubicle, lavatory, and is of many uses.
