Embodiment 1

[0040] Such as figure 1 and figure 2 Shown is the first preferred embodiment of the disinfection cabinet adopting the method of monitoring pulse lamp leakage flash phenomenon in the present invention.

[0041] Such as figure 1 As shown, the disinfection cabinet includes a cabinet body 1 with a disinfection chamber 11, a pulse lamp 2 and a sensor 3 installed in the disinfection chamber 11, the disinfection cabinet has a controller, and the controller is connected to the pulse lamp 2 and the sensor 3 , with a timer.

[0042] Wherein, the pulsed lamp tube 2 can generate pulsed flashes with a wavelength of 200-1100 nm to efficiently sterilize the disinfection chamber 11 . The mechanism of pulse flash sterilization is the synergistic effect of each band in the spectral range, which is mainly reflected in three aspects:

[0043] (1) Photochemical reaction in the ultraviolet band: when the ultraviolet light part of the pulsed strong light spectrum irradiates microorganisms, a ph...

Embodiment 2

[0095] Such as image 3 As shown, it is the second preferred embodiment of the disinfection cabinet adopting the method of monitoring pulse lamp leakage phenomenon in the present invention. The difference with Example 1 is:

[0096] In this embodiment, the sensor 3 is a spectrum collector, which is used to collect the wavelength when the pulse discharge emits light.

[0097] The method for the above-mentioned disinfection cabinet to monitor the phenomenon of leakage of the pulse lamp includes the following steps:

[0098] Step 1. Start: set the disinfection time t 0 , turn on the pulse lamp, sensor and controller, and go to step 2;

[0099] Step 2, the sensor collects light wavelength λ, and enters step 3;

[0100] Step 3. Determine whether λ satisfies: λ min ≤λ≤λ max , if yes (indicating that the sensor has collected the pulsed flash), go to step 4, if not (indicating that the sensor has not collected the pulsed flash), return to step 2;

[0101] lambda min and lambda...

Abstract

The invention discloses a method for monitoring a flash leakage phenomenon of a pulse lamp tube. The method is characterized by comprising the following steps of: step 1, monitoring pulse flash of a pulse lamp tube through a sensor, and calculating a time interval delta t between two adjacent times of discharge of the pulse lamp tube; step 2, judging whether delta t meets the condition that deltat is larger than or equal to T-ti and smaller than or equal to T + ti, if so, returning to the step 1, and if not, enabling n to be equal to delta t / T-1, and rounding off n to obtain the number N of times of flash leakage in a delta t interval; and step 3, judging whether N meets the condition that N is less than Nmax, if so, prompting that the pulse lamp tube has an accidental flash leakage phenomenon, and if not, prompting that the pulse lamp tube works abnormally. The invention also discloses a disinfection cabinet adopting the method. Compared with the prior art, the method provided by theinvention can more accurately monitor the flash leakage frequency of the pulse lamp tube and take grading treatment measures.

Description

technical field [0001] The invention relates to the technical field of kitchen equipment, in particular to a method for monitoring the leakage and flashing phenomenon of a pulse lamp and a disinfection cabinet adopting the method. Background technique [0002] Pulse light disinfection technology is a new type of sterilization technology, which belongs to high-pressure gas discharge. When working, the trigger circuit first applies high voltage to the xenon gas to trigger the ionization of the xenon gas; then the energy storage capacitor charged for a long time discharges instantaneously, causing an avalanche ionization of the xenon gas in the lamp tube, and the xenon gas converts the charged energy in the form of high-intensity light radiation and release, this is a light pulse of pulsed light. After the pulsed lamp has been discharged for a long time (millions of discharges), or there is a fault in the circuit, when the pulsed lamp is discharged, there will be a phenomenon ...
