Description

The invention relates to a water dispenser capable of washing and unloading cold chills and a cold biliary thereof. The application is submitted to the Chinese Patent Office on March 26, 2007, and the application number is 200710090074.9, and the invention name is "a washable cold water drinking fountain and its cold daring The priority of the Chinese Patent Application, the entire contents of which is incorporated herein by reference.

Technical field

The invention relates to the technical field of water dispensers, in particular to a water dispenser capable of washing and unloading cold bladders and a cold bladder thereof.

Background technique

Common hot and cold water dispensers include: the main body of the water dispenser, the cold bladder and the hot bladder. At present, the cold chill of the compressor for the municipal water supply is a water storage component of the water dispenser, or is also called a water storage bucket. As shown in Fig. 1, the cold bladder 5 is directly connected to the water trap 2 on the upper cover 1 of the water dispenser, and the purified water in the water purifier can directly flow into the cold bladder 5 through the water trap 2. Below the water trap 2 is a water barrier 3 for isolating normal temperature water and cold water in the cold bladder 5. A circular hole is formed in the center of the partitioning plate 3, and a normal temperature water outlet pipe 7 is connected to the circular hole. The normal temperature water outlet pipe 7 is connectable to the hot biliary inlet pipe 10 of the hot slab 9. At the same time, the outer tube wall of the room temperature water outlet pipe 7 is also integrally connected to the cold bladder 5. A cold water outlet pipe 6 is also provided on the cold bladder 5, and the cold water outlet pipe 6 is connected to the cold water tap. In addition, on the side wall of the cold bladder 5, an exhaust pipe 8 connected to the hot sulphur 9 is further disposed, and a cooling evaporator for preparing cold water is also wound on the outer wall of the lower portion of the cold chill 5 4.

However, the cold chill in the compressor refrigerating water dispenser is not washable, because: the normal temperature water outlet pipe 7 of the cold urethane 5 is usually directly fixed in the water dispenser by a fixing member such as a fixing cap. On the plate, a check valve is further provided on the normal temperature water outlet pipe 7, so that the room temperature water outlet pipe 7 cannot be completely pulled out. Further, since the exhaust pipe 8 on the side wall of the cold bladder 5 is a hard pipe and one end thereof is caught on the upper cover 1 of the water dispenser, the cold bladder 5 cannot be easily taken out. At the same time, since the cooling pipe of the refrigerating evaporator 4 of the cold bladder 5 is directly wound and fixed to the outer wall of the cold bladder 5, the cold bladder cannot be easily removed and washed.

Since the cold bladder 5 is a necessary component of the waterway and stores water all the time, the pollution is serious. Although it is generally rinsed with clean water or 3% citrate solution, it cannot be rinsed clean. Water can adversely affect the health of the human body.
