第一步：拔去电源插头，取下水桶，打开饮水开关，放去饮水机腔内的剩余水。

The first step: Unplug the power plug, remove the bucket, open the water switch, put the remaining water in the water dispenser cavity.

专家评析：对饮水机消毒的第一步是放出饮水机腔内所有的剩余水。但是，我们平时打开饮水机的笼头，只能放出一小部分水，所以，这种方法存在很大的欠缺。正确做法：先打开饮水机后面的排污管，排净余水。因为排污管里的剩余水才是导致饮水机二次污染的关键，然后，再打开所有饮水开关放水。

Expert evaluation: the first step to disinfect the water dispenser is to release all the remaining water in the dispenser chamber. However, we usually open the dispenser faucet, only a small part of the water release, so this method is very short. The right approach: first open the fountain behind the sewage pipe net water discharge. Because the remaining water in the sewage pipe is the key to the two pollution of the water dispenser, and then turn on all the water switch to drain water.

第二步：用镊子夹住酒精棉花，仔细擦洗饮水机内胆和盖子的内外侧。

Second step: clamp the alcohol and cotton, carefully clean the inner side and the inner side of the lining of the water dispenser and the cover.

专家评析：饮水机的这些部位由于直接与空气接触，很容易积聚细菌。用酒精擦洗，可以去除上面的污垢，为下一步消毒做准备。

Expert comments: these parts of the water dispenser because of direct contact with the air, it is easy to accumulate bacteria. Scrub with alcohol to remove the dirt and prepare for the next step of disinfection.

第三步：往饮水机内胆里倒入300 毫升多功能消毒剂，浸泡10～15分钟。

The third step: to the water pump into the tank 300 ml of multi-function disinfectant, soak for 10~15 minutes.

专家评析：饮水机腔体的容量为2 升左右，区区300 毫升消毒剂，只能消毒极其有限的饮水机内腔空间，这样的消毒是无效的。正确做法：将300 毫升消毒剂溶解到2 升左右的水里，再充盈整个腔体，留置10～15分钟。

Expert evaluation: water dispenser cavity capacity of about 2 liters, a mere 300 ml disinfectant, can only disinfect the very limited water dispenser cavity space, such disinfection is invalid. The correct way: dissolve 300 ml disinfectant into the water of about 2 liters, and then fill the whole cavity for 10~15 minutes.

第四步：打开饮水开关，排净消毒液。

Fourth step: turn on the water switch and clean the disinfectant.

专家评析；如上所述，饮水开关只能放出一部分消毒液，大部分仍滞留在腔体内，如不排尽，会成为新的水质污染源。正确做法：打开饮水机的所有开关，包括排污管和饮水开关，排净消毒液。

Expert comments: as mentioned above, the drinking water switch can only release part of the disinfectant, most remain in the cavity, if not discharged, it will become a new source of water pollution. The correct way: turn on all the switches of the water dispenser, including the drain pipe and the water switch, and clean the disinfectant.

第五步：用1000毫升清水冲洗整个饮水机腔体，然后打开饮水机的所有开关放水。

The fifth step: use 1000 ml of water rinse the entire water chamber, and then turn on all the water dispenser switch, drain water.

评析：用1000毫升清水冲洗是远远不够的，会导致消毒液残留在饮水机内。

Comment: rinsing with 1000 ml of water is far from enough and will result in residual disinfectant in the water dispenser.

正确做法：用7～8升的清水连续冲洗饮水机整个腔体，打开所有开关排净冲洗液体。

Correct method: use 7~8 litres of water to wash the whole cavity of the water dispenser continuously, open all the switches and clean the liquid.
