Technical field

The present invention relates to a kind of automatic vending machine, refer to a kind of automatic vending machine with refrigeration system especially.

Background technology

Automatic vending machine generally includes for refrigerating plant for better preserving goods in it.Existing refrigerating plant is be in the bottom being installed on and safeguarding and need often to be positioned over separately automatic vending machine, by air-flow directly to above blowing to the goods cooling that need freeze.But in use, because shelf in automatic vending machine are by stratum's distribution, the air-flow of blowout is often rebounded by the shelf of lower-order layer, does not reach the refrigeration of expection, power consumption is comparatively large, and easily makes to drip bottom board and form the normal use that ponding affects automatic vending machine.

Summary of the invention

In view of above content, be necessary the automatic vending machine that a kind of good refrigeration effect is provided.

A kind of automatic vending machine, comprise cabinet and some shelf being positioned at cabinet, described shelf vertically press layer arrangement, described some shelf are parallel to each other, gap is provided with between described shelf distance cabinet, described automatic vending machine also comprises refrigerating plant and deep bead, described refrigerating plant is positioned at the bottom of described shelf, be provided with elastic space between the shelf of described refrigerating plant and bottom, the air-flow that described in described deep bead interval, elastic space makes described refrigerating plant blow out blows to the gap of described shelf side.

Preferably, the relatively described shelf of described deep bead are obliquely installed.

Preferably, the angle of inclination of described deep bead and described shelf is 45 degree.

Preferably, described deep bead connects the end of described bottom shelf.

Preferably, described refrigerating plant comprises evaporator, compressor and condenser.

Preferably, described evaporator comprises air outlet and heating radiator, and described heating radiator is positioned at described air outlet place.

Preferably, described evaporator is also provided with fan at described air outlet place, and the relatively described shelf of air-out direction of described fan tilt.

Preferably, the angle of inclination of the relatively described shelf of the air-out direction of described fan is 45 degree.

Preferably, described heating radiator comprises some radiating fins arranged in parallel, is spaced apart 3.8 millimeters between every two radiating fins.

Preferably, conflict described bottom shelf in described deep bead one end, the other end contacts at the side of described air outlet.

Compared with prior art, air-flow directly can be directed to shelf and prevent air-flow own elasticity space from refluxing by described deep bead, thus increases the refrigerating efficiency of refrigerating plant.

Embodiment

Refer to Fig. 1, in an embodiment, a kind of automatic vending machine comprises a rack 10, some shelf 70, refrigerating plant 30 and a deep bead 50.

Described rack 10 is for sealing cabinet is for fixed goods shelf 70.

Refer to Fig. 2, described shelf 70 are for placing some goods 100.Described some shelf 70 are spaced up and down by level and are parallel to each other.Space 80 is provided with between every two adjacent shelf 70.Gap 90 is separated with between described some shelf 70 both sides and rack 10.Described some shelf 70 comprise one first shelf 71,1 second shelf 73, the 3rd shelf 75 and one the 4th shelf 77 from bottom to top.

Described refrigerating plant 30 comprises evaporator 31, compressor 33 and a condenser 35.Described compressor 33 plays a part compression and refrigerant conveying gas, namely the low-pressure low-temperature gas produced in described evaporator 31 is sucked back, is again collapsed into high temperature and high pressure gas and sends into described condenser 35.Described condenser 35 is used for cooling and condensation the high temperature and high pressure gas of compressor press-in, under certain pressure and temperature, the gas liquefaction of High Temperature High Pressure is become normal temperature high voltage liquid.In described evaporator 31, low pressure refrigerant absorbs heat from the external world and is evaporated to gas, environment temperature is reduced, reaches the object of refrigeration.

Please continue to refer to Fig. 3, in an embodiment, described evaporator 31 is provided with an air outlet 311.Described evaporator 31 comprises heating radiator 313 and a fan 315.Described heating radiator 313 and described fan 315 are positioned at described air outlet 311 place.Described heating radiator 313 comprises some radiating fins 3131 arranged in parallel, is spaced apart 3.8 millimeters between every two radiating fins 3131.The bearing of trend of the relatively described radiating fin 3131 of described fan 315 is obliquely installed, and vergence direction can be 45 degree.

Described refrigerating plant 30 is positioned over the bottom of described rack 10, and is positioned at the bottom of described some shelf 70.Elastic space 60 is provided with between evaporator 31 and described first shelf 71.

Described deep bead 50 is tabular, elastic space described in described deep bead 50 interval.The relatively described shelf 70 of described deep bead 50 are obliquely installed.Described deep bead 50 can be 45 degree with the angle of inclination of described shelf 70.Described first shelf 71 of described deep bead 50 one end conflict, the other end contacts at the side of the air outlet 311 of described evaporator 31.Described deep bead 50 can connect the end of described first shelf 71.

Air-out direction relatively described some shelf 70 places plane of described evaporator 31 air outlet 311 tilts, and vergence direction can be 45 degree.

During use, air-flow in described heating radiator 313 blows out from described air outlet 311, under the guiding of deep bead 50, described refrigerating plant 30 is flowed back in the gap 90 between air-flow self-possessed dried food and nuts frame 70 and rack 10 and the space 80 between described shelf 70, makes the refrigeration of the goods on described shelf 70.

The deep bead can guiding described air-flow is not provided in prior art, major part air-flow can flow back to described refrigerating plant 30 from the elastic space 60 between refrigerating plant and described first shelf 71 thus reduce the refrigerating efficiency of described refrigerating plant 30, produces the problems such as ponding.

In above embodiment, the use of deep bead 50 adds the refrigerating efficiency of air current flow, solves ponding problem, prevents from being got rusty by water erosion bottom vending machine.Simultaneously also solve evaporator develops ice and compressor surface ponding problem, avoid evaporating device and fan inside damage, and also eliminate the cold liquid of compressor simultaneously and to reflux the risk that inner rotator may be caused to damage, improve quality and the serviceable life of product.

In addition, in original evaporator, radiating fin spacing is too narrow, easily forms water droplet and is deposited on radiating fin, now namely reduce the flow velocity of wind, also have impact on the heat transfer effect of hot-air and cold radiating fin when hot-air is met cold.Radiating fin spacing by traditional 2.5 millimeters change 3.8 millimeters into, thus increase in evaporator distinguished and admirable by area, prevent ponding on radiating fin and freeze, simultaneously, increase the spacing of radiating fin in same volume thus decrease the quantity of radiating fin, having saved cost.
