Description

The freeze hot drinking water machine of diffusion absorbing refrigeration

The utility model relates to a kind of water dispenser that hot and cold drinking water can be provided, particularly a kind of freeze hot drinking water machine of application diffusion absorption pattern refrigeration.

At present, people improve constantly the requirement of drinking water, the freeze hot drinking water machine of hot and cold drinking water occurred providing at any time.The freeze hot drinking water machine of selling on the market is made up of several big parts such as housing, hot water liner and heat-producing machine thereof, cold water courage and refrigerators thereof usually.It heats and adopts common Electric heating, and the main freon that adopts of refrigeration adds the compressor mode, also has minority to adopt semiconductor refrigerating.The former is higher slightly than latter refrigerating efficiency, has contaminated environment, noise is big, cost is high shortcoming, and installation, maintenance, transportation difficulty, though latter's cost is lower, but has the refrigeration shortcoming that spended time is long, power consumption is big, noise is high.Because the refrigeration part of the two all is not suitable for directly inserting in the cold water courage, thereby refrigeration is all undesirable.

According to the knowledge of the applicant, a kind of diffusion absorption refrigeration technology is arranged, its refrigeration part comprises generator, condenser, absorber, evaporimeter, receiver and connects their gas, liquid pipe etc., it is to utilize thermosiphon principle, and the cold-producing medium ammonia in the receiver is promoted, after the condensation, spreads through hydrogen to evaporimeter through generator, form evaporation, produce refrigerating effect, absorb ammonia by the water in the absorber again and be back to receiver, so move in circles.The refrigerator that has at present just adopts this diffusion absorption pattern refrigeration, and its parts evaporimeter that produces refrigerating effect is the curved shape that spirals usually, is positioned on the inner container of electric refrigerator wall, and its liquid ammonia tube by condenser output is communicated with evaporimeter and is contained on the evaporimeter outer wall.So far not seeing has the freeze hot drinking water machine to adopt this diffusion absorption pattern refrigeration.

The purpose of this utility model is that a kind of freeze hot drinking water machine that adopts diffusion absorption pattern refrigeration is provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of freeze hot drinking water machine of diffusion absorbing refrigeration, its composition comprises housing, hot water liner and heat-producing machine thereof, cold water courage and refrigerating core thereof, refrigerating core is made up of generator, condenser, absorber, evaporimeter, receiver and the gas, the liquid pipe that connect them, the liquid ammonia tube front end that it is characterized in that the evaporimeter of refrigerating core and be communicated with it inserts in the cold water courage, on the cold water bladder wall of their insert divisions the hermetic seal device is housed.

The parts that the utility model will produce refrigerating effect directly insert in the cold water courage, and refrigeration fast, and is effective.To spread the absorption refrigeration technology and be applied to water dispenser, make that this water dispenser has that pollution-free, noiselessness, energy consumption are low, multipotency source, cost and advantages such as efficient is moderate, installation and maintenance convenient transportation, long service life, become the green product of sustainable development.

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.

Fig. 1 is the utility model cold water courage and refrigerating core structural representation thereof.

Fig. 2 is a hermetic seal device architecture schematic diagram among Fig. 1.

As shown in Figure 1, in the utility model freeze hot drinking water engine housing (not drawing among the figure), have hot water liner and heat-producing machine (all not drawing among the figure) and cold water courage 1 and refrigerating core thereof, refrigerating core is by generator 5, condenser 2, absorber 9, evaporimeter 13, receiver 7 and the gas that connects them, liquid pipe: thermal siphon 4, bead tube 3, liquid ammonia tube 11, gas mixing pipe 8, pipe 10 is formed in the evaporation, pipe 10 places evaporimeter 13 in the evaporation, liquid ammonia tube 11 by condenser 2 outputs is communicated with pipe 10 in the evaporimeter, the front end of evaporimeter 13 and liquid ammonia tube 11 inserts in the cold water courage 1, on the cold water bladder wall of their insert divisions hermetic seal device 12 is housed.

In embodiment as shown in Figure 1, the front end of liquid ammonia tube 11 is also inserted in the evaporimeter 13, makes the modular construction compactness of inserting the cold water courage like this, saves the sealing device, and simple installation; Evaporimeter 13 in the insertion cold water courage is type linearly, perhaps has the knuckle of certain angle, increases contact area, strengthens refrigeration; Because evaporimeter drinking water direct and in the cold water courage contacts, and should adopt stainless steel material to manufacture, or manufacture after specially treated with common iron, to meet the requirement of drinking water; The cross section is arranged is the PTC heater block 6 of semi-round ring shape to card on generator 5 outer walls, adopt the PTC heater block to replace original resistance-type heater block, thermal efficiency height heats up rapidly, long service life, thus the operating efficiency of the utility model water dispenser refrigerating core further improved.

The utility model water dispenser refrigeration work process is as follows: the refrigerating fluid in the receiver 7 enters generator 5 after preheating, in thermal siphon 4, be heated to boiling, overcome flow resistance, hoisting depth, wherein ammonia enters bead tube 3, ammoniacal liquor is then separated heating again, purer ammonia enters condenser 2 through bead tube, further cooling becomes liquid ammonia, enter the top of the evaporimeter 13 that is arranged in the cold water courage through liquid ammonia tube 11, ammonia hydrogen mixed gas in evaporimeter in the pipe 10 also enters the evaporimeter top, under the diffusion of hydrogen, the dividing potential drop of ammonia reduces, and liquefied ammonia is evaporated and constantly produces refrigerating effect, make the drinking water in the cold water courage constantly reduce temperature, become satisfactory frozen water below 10 ℃; Be back to receiver 7 after the ammonia solution that concentration is lower is absorbed by the water in the absorber 9, so move in circles.

As shown in Figure 2, hermetic seal device 12 is made up of sleeve pipe 121, pressure ring 123, clip 122, the trip bolt 124 of band flange among the embodiment, sleeve pipe 121 is enclosed within on the evaporimeter 13, pressure ring 123 is pressed on the flange of sleeve pipe, by trip bolt 124 pressure ring and sleeve pipe flange are fixed on the sealing mouth 125 of cold water courage 1 outer wall, clip 122 closely is stuck on the sleeve pipe.This sealing device is simple in structure, easy for installation, effectively sealing.
