Master these tips for repairing and disinfecting cupboards

For catering institutions, commercial disinfection cabinets are used very frequently, so they should pay attention to daily maintenance. If the disinfection cabinet is abnormal, the problem should be found early and solved. For example, Hong Kong Junhong Electrical Appliance Repair Center received a warranty call from a restaurant owner before, so it immediately dispatched technicians to repair the problem. Next, we will use the repair case as a reference to explain the repair skills of commercial disinfection cupboards.

1. What’s wrong with uneven heating of commercial sterilizing cupboards?

Previously, technicians dispatched by Hong Kong Junhong Electrical Maintenance Center encountered a problem of uneven heating of a Wanjiajie disinfection cupboard, so they immediately conducted a professional investigation on it, because the effect of heating and disinfection is far greater for disinfection cupboards. higher than ultraviolet disinfection, so technicians immediately conducted the following professional inspections:

(1) If there is a heating problem when repairing the disinfection cupboard, it is natural to check the heating pipe first. Hong Kong Junhong Electrical Repair Center technicians immediately disassembled the Wanjiajie disinfection cupboard and inspected the heating tube. They found that there were no cracks or scorch marks on the surface of the heating tube. They also used a multimeter to measure its resistance value and confirmed that there was no problem with the heating tube.

(2) After confirming that there is no problem with the heating pipe, look at the thermostat. The thermostat looks at the voltage first and then at the control circuit board. The voltage is still measured with a multimeter. After confirming that it is correct, the motherboard is checked. The measuring personnel found that there is an abnormality in the motherboard. , so the Wanjiajie original temperature control motherboard was replaced.

(3) According to the management technicians, the cooling system of the fan and air circulation fan, that is, the commercial disinfection cupboard, was tested and the heat dissipation effect was good.

2. UV and ozone disinfection are not effective

I just introduced the case of repairing and sterilizing cupboards, and explained how to correctly troubleshoot and solve the problem of uneven heating of commercial sterilizing cupboards. If the power is suddenly cut off after heating, there is a high probability that there is a problem with the cooling system, which causes overheating protection. Let’s talk about it next. A close solution for saying that UV and ozone disinfection in commercial disinfection cabinets is not effective.

(1) When repairing a disinfection cupboard and encountering poor ultraviolet disinfection, disassemble and check the ultraviolet lamp first to confirm that there are no problems such as aging and cracking of the lamp. Obvious dimming and flickering of the lamp indicate aging of the lamp. If If there is a problem, the lamp needs to be replaced.

(2) If the ozone disinfection effect is not good, check the ozone generator. You can start with the sound and circuit. If there is no sound, it means the ozone generator is not running. In terms of circuit, check the voltage and resistance, and use a multimeter to determine whether there is something inside. circuit break phenomenon.

(3) Hong Kong Junhong Electrical Appliance Repair Center encountered a sealing problem when repairing the disinfection cupboard before. Because an odor could be smelled after starting ozone disinfection, the sealing strip of the disinfection cupboard was inspected and found to be aged and cracked, so the entire set was replaced. A new seal then solved the problem.

The above are two cases of repairing disinfection cupboards. For the problem of poor disinfection effect of commercial disinfection cupboards, the main point is to look at the disinfection mode, and then find the problem according to the disinfection mode, and then complete the repair quickly.
