Accompanying drawing explanation
Figure 1 shows that the schematic diagram of the utility model ice temperature refrigerator;
Figure 2 shows that the schematic diagram of cabinet part;
Figure 3 shows that A-A profile.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of the utility model ice temperature refrigerator as shown in Figure 1, comprises pedestal 6, cabinet 9, housing 4, cabinet door 1 and refrigeration system, is installed on described pedestal 6, described pedestal is provided with multiple thermovent 7 after described housing 4 and cabinet 9 combine.The parts of described refrigeration system except evaporation coil 10 are installed in described pedestal 6.Described housing 4 inwall is provided with heat-insulation layer 2, closed chuck layer 3 is formed between described cabinet 9 and heat-insulation layer 2, described cabinet 9 is provided with air outlet 8 in top below, described cabinet front upper is provided with return air inlet 5, the described chuck layer 3 one side top corresponding with described air outlet 8 is separated out plenum chamber 12 by dividing plate 13, described plenum chamber 12 is communicated with described chuck layer 3 by frequency conversion axial flow fan 11, described air outlet 8 is communicated with described plenum chamber 12, and described return air inlet 5 is communicated with described chuck layer 3.Cabinet door 1 place is provided with cabinet door opening and closing sensing element, the output of described cabinet door opening and closing sensing element is connected with the cabinet door open and close controlling signal input part of air curtain starting controller, and the air curtain opening and closing output of described air curtain starting controller is connected with the control end of described frequency conversion axial flow fan 11.Frequency conversion axial flow fan 11 can regulate the air velocity of air curtain according to the unlatching situation of cabinet door 1, reduces refrigerator and exchanges with extraneous caloic, maintains in-cabinet temperature and stablizes.
Described evaporation coil 10 is close to the four sides around described cabinet 9, and the top of described evaporation coil 10 is positioned at the lower end of described air outlet 8 and return air inlet 5.
Described cabinet door 1 is that double glazing is cotton.Cabinet door opening and closing sensing element is pressure inductor.
When cabinet door is in closed condition, frequency conversion axial flow fan 11 is in stopped status.When client open cabinet door select goods time, after cabinet door opening and closing sensing element detects the unlatching of cabinet door, current signal is passed to air curtain starting controller, now air curtain starting controller starts frequency conversion axial flow fan, and the cold airflow of suction is first assembled in plenum chamber, then forms isolation air curtain by air outlet air-supply, by cabinet environment and external environment separated, the caloic reduced inside and outside cabinet exchanges, and maintains the low temperature environment in cabinet, reduces its temperature fluctuation.Fluid enters chuck layer by return air inlet again, under the effect of frequency conversion axial flow fan, then enters plenum chamber from chuck layer, and according to refrigerator different length, the quantity of its frequency conversion axial flow fan can be two or multiple stage.
If the goods putting into cabinet is more, when thermic load is larger, frequency conversion axial flow fan can be manually booted, now frequency conversion axial flow fan works at low frequency, the initial velocity of air curtain is less, initial velocity is 0.2m/s, cold airflow gravitate be bent downwardly very soon with cargo contacts, accelerate the cooling velocity of goods.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
