Description

A kind of goods stores the pump type heat automatic vending machine be separated with refrigeration heating function

Technical field

The present invention relates to automatic vending machine technical field, particularly a kind of goods stores the pump type heat automatic vending machine be separated with refrigeration heating function.

Background technology

In recent years, along with the economic fast development in home market, various types of automatic vending machine quietly rose in various places, became the new fashion of modern shopping.What automatic vending machine for saling commodity were more is beverage and food, and beverage and food control a comparatively stationary temperature scope according to user demand, and therefore this automatic vending machine must load refrigeration or heating system.General and the commercial display cases of domestic existing automatic vending mechanism cold and heating system or refrigerator similar, all freeze in casing, refrigerator takes out commodity at random by people when selling commodity in cabinet, but be to be spued commodity by gear machine according to a fixed sequence during automatic vending machine for saling commodity, people only can buy when using vending purchasing commodity and sell sequence commodity foremost, generally sell sequence foremost with least significant end commodity commercially sell the time difference in a few hours to ten a few hours, if to sell end commodity also freeze (heating) unnecessary energy loss can be caused.During full storehouse refrigeration, all commodity all need cooling, and thermal load is comparatively large, and refrigeration system needs to mate relatively high power, environmental pollution is more serious, and full storehouse refrigeration requires strict for cabinet insulation, whole casing is all with the good material of heat insulation effect, and cost resource input is larger.

According to incompletely statistics, at present only in Beijing, Shanghai, Guangzhou, Tianjin, Shenyang, Xi'an, Hangzhou, Kunming, the ground such as Shenzhen various automatic vending machines be increased to 30.2 ten thousand in 2013 by 30,000 multiple stage of 2004.Automatic vending machine due to needs work in 24 hours, thus causes a large amount of energy consumption.According to statistics, the energy that Japanese automatic vending machine consumption is a large amount of, its summation equals the energy that 2 nuclear power generation heaps export.Therefore, the energy resource consumption reducing automatic vending machine is extremely important.

In order to realize energy-conservation object, researchist is had to improve existing automatic vending machine, Authorization Notice No. be the Chinese patent literature of CN203179154U disclose a kind of to by beverage vending utensil heating or refrigeration device, comprise casing, door, vertical storage and the commodity goods road that spues, air channel, chute board, heat interchanger and wind-tunnel, the confined space of described casing and door termination is built with vertically storing and spue commodity goods road, the commodity of vertical storage and the inside, commodity goods road that spues skid off on chute board by gravity fall, the box house back side is fixed in air channel, wind path adjustment cylinder is connected below air channel, wind path adjustment cylinder front end connects heat interchanger, heat interchanger is fixed on box house lower surface, heat interchanger outlet air surface connects wind-tunnel, wind turbine apparatus central authorities are provided with fan, wind angular setting plate is installed in wind-tunnel front end.Said apparatus only heats the beverage come near outlet or freezes, and can reduce the energy consumption to overall space heating or refrigeration like this.
