Abstract
The utility model relates to a novel efficient air-cooled electric refrigerator, which is provided with a refrigerating chamber, a freezing chamber, and an air duct device composed of a motor, a fan, and air duct volutes. The upper and the lower layers of air duct volutes are connected into one body; an air outlet of the upper layer of volute is communicated with the refrigerating chamber, and an air outlet of the lower layer of volute is communicated with the freezing chamber; the motor adopts a DC brushless motor. By the double-layer of the air duct volute, cold air can be reasonably distributed the refrigerating chamber and the freezing chamber; with adoption of the DC brushless motor, the regulation of changed wind speed and the optimization of cold quantity and noise are easy to realize, and the refrigerant effect of the electric refrigerator can be improved.
Description
The utility model relates to a kind of freezing equipment, particularly a kind of air-cooled refrigerator.
At present, air-cooled refrigerator generally adopts with axial flow blower and the air channel thereof of alternating current generator as drive unit, and the cooling air circulates between freezer compartment of refrigerator, refrigerating chamber in the air channel, effect lower edge of aerofoil fan.The running of the general only quota of axial flow blower, when the refrigerator load variations, its air quantity, cold can't be regulated, thereby are difficult to realize that refrigerator cools off fast, can't improve the effect of refrigerator.The air-duct apparatus of refrigerator only relies on the pressure reduction in the air channel to carry out Flow-rate adjustment, can't carry out assignment of traffic to refrigerating chamber and refrigerating chamber, and when bigger variation takes place the air channel internal resistance, easily departs from blower fan design conditions point, and electric efficiency is descended, and noise increases.
The purpose of this utility model is, overcomes the weak point that above-mentioned air-cooled refrigerator exists, and provides a kind of and can carry out the new and effective air-cooled refrigerator that air quantity is regulated and distributed automatically.
The purpose of this utility model is achieved through the following technical solutions: a kind of new and effective air-cooled refrigerator, the air-duct apparatus that has refrigerating chamber, refrigerating chamber and form by motor, fan, air-duct spiral case, it is characterized in that having the upper and lower two-layer air-duct spiral case that connects as one, upper strata spiral case air outlet is communicated with refrigerating chamber, lower floor's spiral case air outlet is communicated with refrigerating chamber, and motor adopts dc brushless motor.
The utility model is by specially designed double-deck air-duct spiral case, make a cold wind part that circulates through heat exchange in the refrigerator blow to refrigerating chamber through upper strata spiral case water conservancy diversion, another part blows to refrigerating chamber through lower floor's spiral case water conservancy diversion, the height of double-deck spiral case designs by a certain percentage, cold wind is obtained an equitable breakdown in required ratio between refrigerating chamber and refrigerating chamber, realize the refrigeration of refrigerating chamber and the cooling of refrigerating chamber.As long as change the height of upper and lower layer spiral case, just can realize the change that air quantity distributes.Simultaneously; owing to adopt dc brushless motor; be easy to it is carried out PID (PID adjusting) control; blower fan was run up in the refrigerator high load capacity phase; fast cooling, and through the normal or low-speed running of rear fan after a while is when becoming wind speed and regulating; also realize the optimization of cold and noise, improved the refrigeration effect of refrigerator.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is the utility model Air duct of refrigerator apparatus structure schematic diagram (cut open and show).
Fig. 2 is the vertical view (removing outlet grid 6 and motor 5 among Fig. 1) of Fig. 1.
As depicted in figs. 1 and 2, the utility model high-efficiency air cooling formula refrigerator, the air-duct apparatus that has refrigerating chamber (4 are the refrigerating chamber cover), refrigerating chamber (meaning not shown in the figures) and form by motor 5, fan 2, air-duct spiral case 1,3, upper and lower two-layer air-duct spiral case 1,3 connects as one, fixedly connected with refrigerating chamber cover 4, the air outlet of upper strata spiral case 1 is communicated with refrigerating chamber, the air outlet of lower floor's spiral case 3 is communicated with refrigerating chamber, motor 5 is a dc brushless motor, be fixedly mounted on the centre of outlet grid 6, fan 2 is contained on the motor 5, is arranged in double-deck spiral case.
Among the embodiment, fan 2 adopts centrifugal fan, cooperates with dc brushless motor 5 and double-deck spiral case 1,3, and air-out effect is good, is easier to realize becoming effective control that wind speed is regulated and air quantity distributes; The height of upper strata spiral case guarantees that greater than the height of lower floor's spiral case most of cold wind blows to refrigerating chamber, and fraction cold wind blows to refrigerating chamber.
