概述
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.

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 :飲水機是將桶裝純淨水（或礦泉水）升溫或降溫並方便人們飲用的裝置。
飲水機以電源為動力，若飲水機發生漏電、絕緣不良等，都極為危險。消費者在選購時首先要認準產
品的品牌和經過中國電工安全認證委員會CCEE產品認證標誌。
類型選擇
在眾多品牌、型號飲水機產品中，歸納起來不外乎是溫熱、冰熱、冰溫熱三種類型，冰熱機又分半導體製冷飲水機和壓縮機式製冷飲水機兩種。決定買什麼類型的飲水機，主要從飲水人數和製冷速度來考慮。就製冷速度而言，在製冷時間相同情況下，壓縮機式製冷飲水同要比半導體製冷飲水機快得多，冰水供應量也比後者多。因此，壓縮機式製冷飲水機適合飲水人數較多的場合，例如集團公司、事業單位、會議室、寫字樓、辦公室、酒吧、卡拉OK廳等。而人數不多的單位、賓館客房和一般家庭等，選購半導體製冷飲水機就足夠了。
價格比較
不同製冷類型的飲水機售價有很大差異。一般來說，壓縮機式製冷飲水機的成本要比半導體制冷機高得多，因而價格一般是半導體製冷飲水機的2－3倍。另外，同一類型功能相同的飲水機又分有台式（又稱座式）和立式（又稱落地式）機型。按習慣稱台式的為普及型飲水機，而立式的豪華型飲水機。一般來說，台式飲水機單台售價比立式飲機便宜1/3。
功能選擇
從功能使用考慮選購飲水機，這一點頗為重要。如果不喜愛用飲水機調製冷飲的，日常只用於泡茶和沖咖啡，購買一台溫熱飲水機就可以了，既實用又經濟，如果年輕人較多，加上地處南方熱帶地區，夏季使用率較高，
且又喜歡冷飲者，則應購買冷熱飲水機。另外，還有冰溫熱三用機，可根據需要選擇。
外觀 飲水機噴塑件表面應光滑平整，色澤均勻，深層牢固，不應有裂痕、劃傷、起泡等缺陷，各接縫處連線勻稱。 通水試驗檢查 外觀確定以後，下一步是通水試驗檢查後，方法和步驟如下： 首先檢查飲水機頂蓋，若沒有聰明座的，說明進水系統不具備預防二次污染，此類飲水機不宜選購。聰明座裝入要牢固，拆卸應順暢。導柱與聰明座螺紋結合要牢固；若有鬆動，不能擰緊，說明導柱與聰明座螺紋結合不良，日後使用，導柱根部容易脫出或折斷。瓶裝水注入水箱（一般注水2－3次）後，不按下水龍頭，水龍頭不應出現滴水現象（水龍頭密封正常）；觀察水桶水位，若水位急劇下降，說明機內有漏水（橡膠接管頭脫出產生漏水的致），不宜選購；按下水龍頭按手（製冷經過1.5－2秒，制熱約經過2－2.5秒），水龍頭應有水流出來，出水流暢，說明飲水器功能正常。倘若沒有出水或出水慢，說明進水有阻塞或此機不正常。 將水桶插到聰明座之後，水桶的水自動流入冷膽熱罐，由於桶內壓差作用，桶內應有氣泡上升並出現間斷性的響聲；按下水龍頭按手，氣泡、響聲隨之消除，說明進水正常。檢查冷膽、熱罐排水管的膠塞是否牢固，有沒有卡環卡牢膠塞。 電氣性能檢查 注水，接通電源，按動製冷、制熱電源開關數次，開關接觸應良好，相應指示燈隨之顯示，表示飲水機電路基本正常。按下製冷開關，用手靠近背板風口，有排風感，聽不到噪聲中噪聲很弱，風機運轉正常。通電2小時後，按下製冷水龍頭，應有冷水流出。如半導體製冷，可使冰水溫度降至5－15℃，壓縮機式製冷可使冰水溫度降至4－12℃。按下制熱開關，加熱15－20秒，水溫應達到92－96℃。期間，加熱指示燈會自動啟亮、熄滅。帶消毒功能的飲水機，按下消毒按鈕，規定時間內消毒後，應能自動關斷電源，指示燈熄滅。檢查電源線絕緣膠層應無損傷，使用足夠容量電源線及專用電源插頭。 售後服務 選購時可事先索要保修卡，仔細閱讀一下，如沒有保修卡，最好不要購買。此外，最好購買當地有保修部門的廠家的飲水機。有的廠家（銷售商）還提供清洗、消毒服務，消費者應綜合考慮。
