Abstract

The utility model relates to a high-efficiency ozone disinfection cabinet, which is composed of a cabinet body, a control circuit and an ozone generating device. The ozone is generated by a low temperature plasma generator, which saves energy; when the high-efficiency ozone disinfection cabinet works, the temperature in the cabinet is not rose, and most of materials and articles are optimized to adopt. The utility model is provided with a spare control circuit, and when the self-control circuit is damaged in case, the high-efficiency ozone disinfection cabinet still can continue to work.

Description

A kind of efficient ozone disinfection cabinet

This utility model relates to a kind of material or object disinfectant device, especially can be used for food and food material or article sterilization and disinfectant device in addition.

Commercially available disinfection cabinet is broadly divided into two classes at present: a class is the disinfection cabinet of electric heating, and its principle is to convert heat energy to electric energy (passing through electrothermal tube), and the rising in-cabinet temperature is sterilized, sterilized.Its shortcoming is that power consumption is big, and is sterilized thing and must be able to stands high temperature and do not damaged.Another kind of is the disinfection cabinet that produces ozone sterilization with the discharge tube interpolar discharge, newer technology has ZL93203751.8 ozone cotton-wadded quilt disinfection cabinet in this class disinfection cabinet, this cabinet does not have harsh requirement to being sterilized thing, the scope that is sterilized thing is wider, but because discharge tube generation ozone efficient is lower, do not reach ideal Disinfection Effect, and the life-span of discharge tube is also shorter.

The purpose of this utility model be to provide a kind of consume energy low, efficient is high, the disinfection cabinet of long service life.

Its technical scheme is: a kind of efficient ozone disinfection cabinet, constitute by cabinet, control circuit and ozone generating apparatus, it is characterized in that ozone generating apparatus is made of oscillating circuit, high-frequency impulse assembly and low-temperature plasma generator, the input of the output termination high-frequency impulse assembly of oscillating circuit, the two poles of the earth lead-in wire of the output termination low-temperature plasma generator of high-frequency impulse assembly.

Used low-temperature plasma generator is that one two surperficial coating electrode, and the insulation board of two lead-in wires of ining succession (pottery or glass), can excite low temperature plasma in the surface of sheet with high-frequency impulse, thereby produces a large amount of ozone in its surrounding air.

The disinfection cabinet power consumption of electric heating is in a kilowatt magnitude, and this utility model is the magnitude work at ten watts; Produce per hour 0.5～6 milligram of ozone amount with ozone generating pipe, and this utility model produces ozone amount per hour more than 600 milligrams with low-temperature plasma generator.So this utility model consumes energy less by comparison, the efficient height, and bactericidal effect is good.From service life, low-temperature plasma generator is also much longer than discharge tube.

To contrast accompanying drawing below and further describe by embodiment.

The drawing explanation:

Fig. 1 is the structure chart of embodiment;

Fig. 2 is the control circuit figure of embodiment;

Fig. 3 is the oblique view of low-temperature plasma generator.

Embodiment is to be the disinfection cabinet of object with tableware, kitchenware and fruit and vegerable.

As shown in Figure 1, its cabinet is divided into body 6 and cabinet door 15 two parts, establish upper, middle and lower-ranking thing frame 3,4,5 in the body, control chamber 7 is arranged at the bottom, built-in control circuit, electrical part exposed parts have gate controlled switch 1, relay indicating light 8, power supply indicator 9, intervalometer 10, fuse 11, on and off switch 12.Its control circuit (see figure 2) comprises automatic control circuit and the parallel control circuit of (standby) timing circuit two-way, the 220V civil power is a power supply, receive power supply indicator 9 by on and off switch 12 and fuse 11, the head end of automatic control circuit and timing circuit, automatic control circuit is by gate controlled switch 1, delay circuit 17 and its relay J constitute, the gate controlled switch set A intraoral illumination lamp of receiving at the counter, set B connects delay circuit, and connect the parallel circuit of relay indicating light and oscillating circuit by relay contact j, the winding of relay J is connected on the delay circuit, for the negative half-cycle current relay winding of releasing diode in parallel; Timer circuit as standby manual control circuit is made of intervalometer 10, the K point of a termination gate controlled switch, termination oscillating circuit, parallel with automatic control circuit in addition; Ozone generating apparatus is made of low-temperature plasma generator 2, high-frequency impulse assembly 19 and oscillating circuit 18, and the output termination high-frequency impulse assembly input of oscillating circuit, high-frequency impulse assembly outfan are received on the two poles of the earth lead-in wire of low-temperature plasma generator.Low-temperature plasma generator places the upper middle position of cabinet, puts a porous outer housing.

As shown in Figure 3, the substrate of the used low-temperature plasma generator of present embodiment is to be coated with on 20, two surfaces of sheet glass to be coated with electrode 21, two ends leaded 22.When adding high-frequency impulse, the two poles of the earth produce low temperature plasma along glass surface.

Present embodiment under normal circumstances, automatic control circuit work, timer circuit open circuit, power supply indicator is bright when adding power supply; When the cabinet door is in opening, gate controlled switch 1 places the A position, and cabinet intraoral illumination lamp is bright, puts B position open circuit; Switch 1 is put disconnection A position, B position when the cabinet door is closed, lighting-off, delay circuit and relay thereof start, contact j closure, and ozone generating apparatus is started working, relay indicating light is simultaneously bright, at this moment produce ozone in the low-temperature plasma generator surrounding air, to the cabinet internal diffusion, cut off automatically to scheduled time delay circuit by foraminous shield, separate J and open a way again, ozone generating apparatus quits work.Can not work and should not in time repair the time, can manually boot timer circuit and make its work when automatic control circuit breaks down to the ozone generating apparatus power supply.
