Description
Technical field
The present invention relates to automatic vending device, particularly instant heating cold-instantly type cold, hot two-purpose automatic vending device and supply of material method thereof.
Background technology
Along with the raising of people's living standard, the quickening of movement of population speed, this conveniently mode of selling goods of automatic vending machine receives the welcome of consumer and retailer, and demand constantly increases.Although single automatic vending machine energy consumption is not high, due to its substantial amounts, overall energy consumption is still more remarkable.In addition automatic vending machine in the past all only provides freezing commodity mostly, does not have heating function, can not meet crowd's demand widely.Therefore be necessary from energy-conservation and meet crowd demand's angle and make improvement to automatic vending machine.
Traditional automatic vending machine adopts the structure being similar to refrigerator.Namely all goods all exist in a thermal-insulating body, provide cold by refrigeration system, all goods are wherein remained on a lower temperature.When commodity selling, from casing, take out commodity.Because every day, all only some commodity can be sold, the most energy consumption of such system is the insulation of whole casing.Because casing is larger, overall need a large amount of high-quality insulation materials, have higher requirement to the refrigerating capacity of refrigeration cycle and refrigeration work consumption simultaneously.
Chinese patent literature CN203179154U gives a kind of, and to the device by beverage vending utensil heating or refrigeration, it only heats the beverage come near outlet or freezes, and can reduce the energy consumption to overall space heating or refrigeration like this.But this mode can not tackle the period of harvest yield change well, when the amount of selling goods is very large, this mode obviously cannot meet the demand providing cold drink; When the amount of selling goods is little, its insulation energy consumption is higher equally.In addition, owing to can not fully separate by import and export part and remainder, reduction of its insulation energy consumption is unsatisfactory.
Conventional dispensers with only the cold that refrigeration cycle vaporizer side produces, and the heat of condensation end is directly got rid of.This way is not only the waste to energy, also can cause adverse influence to environment simultaneously.In order to put forward high-octane utilization factor, Chinese patent literature CN101285034A provides a kind of method that simultaneously can to utilize in refrigeration cycle heat in cold and condenser in evaporator.But its general refrigerant adopted, condensation end temperature can only reach 20 ~ 35 DEG C, and such heating temperatures commodity are far from being enough, or the time of heating can be very long, can not meet the needs of consumer.
Also there is a common defect in above two patents, namely carries out heat to a large amount of food and preserve, be kept at for a long time in thermal environment by food, is easy to occur to go bad, is unfavorable for long-term preservation, is therefore necessary to carry out synthesis improvement to it.

Time customer selecting " hot drink ", beverage enters heat-producing machine from normal temperature storage unit; Between restricting element and fluid reservoir, between restricting element and evaporation element, between compressor outlet and refrigerator, flowrate control valve is all opened, compressor start.The high temperature and high pressure gas of compressor outlet enters heat-producing machine, and heat release in heat-producing machine, beverage then heating temperature raises.After having heated, hot drink is launched to client from hot drink outlet.Cold-producing medium is then exported by heat-producing machine and enters fluid reservoir storage.
For the device being provided with hot junction accumulator, partial heat during beverage heating is provided by hot junction accumulator, if the heat stored is enough, then directly adopt hot junction accumulator to heat; For the device being provided with cold junction accumulator, after throttling, gas-liquid two-phase cold-producing medium enters cold junction accumulator and releases cold.
Current without customer demand time, device is " standby " duty.Fluid reservoir outlet flow control valves, refrigerant inlet flowrate control valve, heat-producing machine inflow control valve, hot junction and cold junction accumulator inflow control valve are all closed, and compressor does not work, and now rating of set is minimum.
Described flow control valve is automatic valve, controls, to control the circulation of refrigerator and the heat exchange amount of each heat transmission equipment by control module is unified.
Beneficial effect of the present invention:
Automatic vending device of the present invention and method, cooling and warming cycling element compressor discontinuous operation, only immediately heat when customer demand hot drink, major part beverage then stores at normal temperatures, effectively prevent and repeatedly heat the quality that causes and decline and the problem such as shortened shelf life, beverage flavor is better, is more conducive to the healthy of people; Store the heat produced with the thermogenetic cold of system or refrigeration, and use in follow-up supply of material process, device discontinuous operation, effectively reduces energy consumption, saves energy; By means of only the cooling completed in a cooling and warming circulating device beverage or heating, reduce the complexity of system, make system cloud gray model more reliable.
