water dispenser

在众多品牌、型号饮水机产品中，归纳起来不外乎是温热、冰热、冰温热三种类型，冰热机又分半导体制冷饮水机和压缩机式制冷饮水机两种。决定买什么类型的饮水机，主要从饮水人数和制冷速度来考虑。就制冷速度而言，在制冷时间相同情况下，压缩机式制冷饮水同要比半导体制冷饮水机快得多，冰水供应量也比后者多。因此，压缩机式制冷饮水机适合饮水人数较多的场合，例如集团公司、事业单位、会议室、写字楼、办公室、酒吧、卡拉OK厅等。而人数不多的单位、宾馆客房和一般家庭等，选购半导体制冷饮水机就足够了。

从功能使用考虑选购饮水机，这一点颇为重要。如果不喜爱用饮水机调制冷饮的，日常只用于泡茶和冲咖啡，购买一台温热饮水机就可以了，既实用又经济，如果年轻人较多，加上地处南方热带地区，夏季使用率较高，

且又喜欢冷饮者，则应购买冷热饮水机。另外，还有冰温热三用机，可根据需要选择。

外观　饮水机喷塑件表面应光滑平整，色泽均匀，深层牢固，不应有裂痕、划伤、起泡等缺陷，各接缝处连接匀称。　通水试验检查　外观确定以后，下一步是通水试验检查后，方法和步骤如下： 　首先检查饮水机顶盖，若没有聪明座的，说明进水系统不具备预防二次污染，此类饮水机不宜选购。聪明座装入要牢固，拆卸应顺畅。导柱与聪明座螺纹结合要牢固；若有松动，不能拧紧，说明导柱与聪明座螺纹结合不良，日后使用，导柱根部容易脱出或折断。瓶装水注入水箱（一般注水2－3次）后，不按下水龙头，水龙头不应出现滴水现象（水龙头密封正常）；观察水桶水位，若水位急剧下降，说明机内有漏水（橡胶接管头脱出产生漏水的致），不宜选购；按下水龙头按手（制冷经过1.5－2秒，制热约经过2－2.5秒），水龙头应有水流出来，出水流畅，说明饮水器功能正常。倘若没有出水或出水慢，说明进水有阻塞或此机不正常。 　将水桶插到聪明座之后，水桶的水自动流入冷胆热罐，由于桶内压差作用，桶内应有气泡上升并出现间断性的响声；按下水龙头按手，气泡、响声随之消除，说明进水正常。检查冷胆、热罐排水管的胶塞是否牢固，有没有卡环卡牢胶塞。　电气性能检查　注水，接通电源，按动制冷、制热电源开关数次，开关接触应良好，相应指示灯随之显示，表示饮水机电路基本正常。按下制冷开关，用手靠近背板风口，有排风感，听不到噪声中噪声很弱，风机运转正常。通电2小时后，按下制冷水龙头，应有冷水流出。如半导体制冷，可使冰水温度降至5－15℃，压缩机式制冷可使冰水温度降至4－12℃。按下制热开关，加热15－20秒，水温应达到92－96℃。期间，加热指示灯会自动启亮、熄灭。带消毒功能的饮水机，按下消毒按钮，规定时间内消毒后，应能自动关断电源，指示灯熄灭。检查电源线绝缘胶层应无损伤，使用足够容量电源线及专用电源插头。　售后服务　选购时可事先索要保修卡，仔细阅读一下，如没有保修卡，最好不要购买。此外，最好购买当地有保修部门的厂家的饮水机。有的厂家（销售商）还提供清洗、消毒服务，消费者应综合考虑。

water Dispenser to power as a driving force, if leakage occurred fountains, bad insulation, are extremely dangerous. First of all, when consumers buy products to look for the brand and electrical safety certification through the Commission of China among the many brands, models dispenser products can be summed up in nothing more than hot, hot ice, three types of hot ice, ice and sub-semiconductor heat engine and compressor cooling water dispenser refrigeration of two drinking fountains. Decided to buy the types of drinking fountains, mainly from drinking water and cooling rate of the number to consider. On the cooling speed, in the same period of time under refrigeration, refrigeration compressor with water much faster than the semiconductor cooling water dispenser, water supply and more than the latter. Therefore, the refrigeration compressor suitable for drinking water fountains in a large number of occasions, such as group, institutions, conference rooms, office space, offices, bars, karaoke halls OK. The small number of units, hotel rooms and the general families, to buy semiconductor refrigeration enough drinking fountains.

Price comparison

Feature selection

Consider buying from the functional use of water dispenser, which is important. If you do not like to use cold water dispenser modulation, and day-to-day is used only for tea and instant coffee, buy a hot water dispenser on the can, both functional and economic, if more young people, together with the South is located in tropical areas, the summer of heavy utilization,且又like cold, and should be the purchase of hot and cold water dispenser. In addition, there are three warm with ice machine, can be choose.

Appearance

Spray dispenser surface should be smooth, uniform color, deep sound, there should be no cracks, scratches, defects such as foaming, the seams connecting symmetry.

Test water

After determining the appearance, the next step is after the water test, methods and steps are as follows:

First check the water dispenser cap, if there is no smart-seater that does not have the water system to prevent secondary pollution, such fountains should not buy. Into a solid block to smart, demolition should be smooth. Block and the Smart Guides to strong thread binding; if loose, can not be tightened on Block I. threaded column and clever combination of bad, for future use, guide column or break off the roots easily. Bottled water into the tank (usually water 2-3 times), the do not press the tap, tap water should not be the phenomenon (the normal water seal); observation bucket water level, if water levels are falling sharply, and that there is water leakage machine (rubber to take over first extrusion to produce leakage), not to buy; press the tap by hand (1.5-2 seconds after cooling, after heating of about 2-2.5 seconds), tap water should be out of the water flow on the normal function of drinking water. If there is no water or water slowly, and that water blockage or abnormality of this machine.

Check the electrical performance

Water, access to power, rather than pressing the refrigeration, heating power switch several times, switching contacts should be good, then the corresponding indicator light shows that the normal drinking fountains circuit. Press the refrigeration switch, with his hands near the back air, and exhaust flu did not hear any noise in the weak noise, fan is operating normally. Electricity after two hours, press the cooling water, cold water outflow due. Such as semiconductor refrigeration, to enable the water temperature 5-15 ℃, refrigeration compressor to enable the water temperature 4-12 ℃. Press the heating switch, heating 15-20 seconds, the water temperature should reach 92-96 ℃. During the heating indicator light will automatically Qiliang, extinguished. Drinking fountains with disinfectant function, press the disinfect button and the time after disinfection should be able to automatically turn off power indicator goes out. Check the power cord insulation layer should be no damage, the use of sufficient capacity and a dedicated power cord plug.

After-sales service

May request in advance to buy the warranty card, read carefully, if there is no warranty card, it is best not to buy. In addition, it is best to buy local manufacturers warranty fountains sector. Some manufacturers (vendors) also provides cleaning and disinfection services, consumers should be considered.

water Dispenser :饮水机是将桶装纯净水（或矿泉水）升温或降温并方便人们饮用的装置。

饮水机以电源为动力，若饮水机发生漏电、绝缘不良等，都极为危险。消费者在选购时首先要认准产

品的品牌和经过中国电工安全认证委员会CCEE产品认证标志。

不同制冷类型的饮水机售价有很大差异。一般来说，压缩机式制冷饮水机的成本要比半导体制冷机高得多，因而价格一般是半导体制冷饮水机的2－3倍。另外，同一类型功能相同的饮水机又分有台式（又称座式）和立式（又称落地式）机型。按习惯称台式的为普及型饮水机，而立式的豪华型饮水机。一般来说，台式饮水机单台售价比立式饮机便宜1/3。
