Description

The pump type heat automatic vending machine that a kind of goods storage is separated with refrigeration heating function

Technical field

The present invention relates to automatic vending machine technical field, what more particularly to a kind of goods storage was separated with refrigeration heating function Pump type heat automatic vending machine.

Background technology

In recent years, with the economic fast development in domestic market, various types of automatic vending machines are quietly emerging in various regions Rise, as the new fashion of modern times shopping.Automatic vending machine for saling commodity are more for beverage and food, and beverage and food are according to using Demand modeling at one compared with stationary temperature scope, therefore the automatic vending machine must load refrigeration or heating system.The country is existing There are automatic vending mechanism cold and heating system typically similar with commercial display cases or refrigerator, all freeze in casing, refrigerator vendors Commodity are taken out out of cabinet by people at random during product, but are by gear machine according to certain sequence during automatic vending machine for saling commodity Discharge commodity, people can only buy when using vending purchasing commodity and sell the commodity of sequence foremost, typically sell Sequence foremost with least significant end commodity commercially sell the time difference in a few hours to ten a few hours, if to selling end commodity Also freezed (heating) unnecessary energy loss can be caused.All commodity are required for cooling during full storehouse refrigeration, thermic load compared with Greatly, refrigeration system needs to match relatively high power, and environmental pollution is more serious, and full storehouse refrigeration is tight for cabinet insulation requirement Lattice, whole casings will use the preferable material of heat insulation effect, and cost resource input is larger.

According to incompletely statistics, at present only on Beijing, Shanghai, Guangzhou, Tianjin, Shenyang, Xi'an, Hangzhou, Kunming, Shenzhen and other places Various automatic vending machines 30.2 ten thousand in 2013 were increased to by more than 30,000 in 2004.Automatic vending machine is due to needing 24 Hour work, so as to cause a large amount of energy consumptions.According to statistics, Japanese automatic vending machine consumes substantial amounts of energy, and its summation is equal to 2 cores The energy of power generation stack output.Therefore, the energy resource consumption for reducing automatic vending machine is extremely important.

In order to realize the purpose of energy-conservation, there is researcher to be improved existing automatic vending machine, Authorization Notice No. is CN203179154U Chinese patent literature discloses a kind of device to beverage vending utensil is heated or freezed, including case Body, door, vertical storage and discharge commodity cargo path, air channel, chute board, heat exchanger and wind-tunnel, the casing and door termination it is closed Space built with vertical storage and discharge commodity cargo path, commodity inside vertical storage and discharge commodity cargo path by gravity fall in Skidded off on chute board, connection wind path adjusting cylinder below the box house back side, air channel, the connection of wind path adjusting cylinder front end are fixed in air channel Heat exchanger, heat exchanger is fixed on box house lower surface, and heat exchanger outlet air surface connects wind-tunnel, and wind turbine apparatus center is provided with wind Fan, wind-tunnel front end is installed by wind angle adjustment plate.Said apparatus is only heated or freezed to the beverage come close to outlet, this Sample can reduce the energy consumption for heating or freezing to overall space.

But it is due to that the change that can not tackle sales volume exactly is adjusted, when the amount of selling goods is very big, this mode is bright It is aobvious to meet the demand that cold drink is provided;And when the amount of selling goods is small, it is equally higher that it is incubated energy consumption.Further, since leaning on Importing and exporting part and remainder can not be sufficiently spaced from, and the reduction that it is incubated energy consumption is unsatisfactory.

The content of the invention

, can basis the invention provides the pump type heat automatic vending machine that a kind of storage of goods is separated with refrigeration heating function The kinds of goods for needing refrigeration heating quantitative, the temperature remains within the normal range for the memory block of separation, effectively the operation energy consumption of reduction automatic vending machine, obtains More preferable economic benefit.
