Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Figure label：1 first temperature sensor, 2 second temperature sensors, 3 third temperature sensors, 4 the 4th temperature pass
Sensor, 5 return air inlets, 6 fans, 7 thermal baffles, 8 air outlets, 9 air duct at top, 10 rear side air ducts, 11 bottom air ducts, 12 evaporations
Device.
Specific implementation mode
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
Referring to Fig. 1, present embodiment discloses a kind of air curtain regulating device of refrigerated display case, which includes cabinet
Body, cabinet front side middle and upper part opening, cabinet inner wall are provided with cooling air duct, evaporator 12 and fan 6, cabinet are equipped in cooling air duct
Body front openings top is equipped with air outlet 8, and cabinet front openings bottom end is equipped with return air inlet 5, and cold wind is blown into outlet air from cooling air duct
Mouth 8, and flowed downward from air outlet 8 to form refrigeration air curtain at cabinet front openings, and pass through the return air inlet of lower section 5
It is back to cooling air duct bottom and forms circulated air, there are one horizontal exhausted being set at return air inlet 5 on the front side liner of cabinet
Hot partition board 7,7 top and bottom of thermal baffle are respectively arranged with the first temperature sensor 1, second temperature sensor 2, before cabinet
Third temperature sensor 3 is being provided at return air inlet 5 outside side, cabinet top outer is provided at air outlet 8
4th temperature sensor 4, the first temperature sensor 1, second temperature sensor 2, third temperature sensor 3 and the 4th temperature sensing
Device 4 is electrically connected with controller, and controller controls the rotating speed size of fan 6 by the temperature signal of four temperature sensors.
Cooling air duct includes sequentially connected air duct at top 9, rear side air duct 10, bottom air duct 11, and fan 6 is arranged in bottom
