Description
Technical Field
The invention belongs to the technical field of refrigerator air duct system control, and particularly relates to a refrigerator air multiplication air duct system and a control method.
Background
The air-cooled refrigerator is increasingly popular with consumers because of high refrigerating speed and uniform temperature and no need of manual defrosting by users. The air-cooled refrigerator mainly depends on a cooling fan and an air duct system to send cold air generated by an evaporator to each space of the refrigerator. The cooling fan used in the current air-cooled refrigerator is generally a radial fan or an axial fan. The air duct generally adopts a multi-branch scheme with a plurality of air outlets and a plurality of air inlets. The design mode has the defects of small air quantity, slow air flow in the refrigerator and uneven temperature, and is not beneficial to food preservation. On the other hand, if the fan is operated to increase the fan air volume in order to increase the air flow rate, the noise is increased.
The principle of air multiplication is that a negative pressure area is generated near a nozzle by utilizing high-speed moving air jet generated by a jet pump, so that surrounding air is driven to move. The moving air flow driven by the air multiplication principle can reach dozens of times of the sucked air flow.

A refrigeration program control method of a refrigerator air multiplication air duct system comprises the following steps:
s1: starting;

s12: turning off the compressor and turning off the gas rotation accelerator;

Further, the air flow direction when the refrigerating chamber is refrigerated is as follows: evaporator → cyclone accelerator → duct a section → duct B section → duct C section → refrigerator → duct D section → evaporator.
Further, the air flow direction when the freezing chamber is refrigerated is as follows: evaporator → cyclone accelerator → duct a section → freezer → evaporator.
The invention has the following beneficial effects:
1. the air channel system of the refrigerator, which is manufactured by utilizing the air multiplication principle, is provided with the evaporator, the cyclone accelerator and the like, and can quickly drive air in a space to flow due to the fact that the air channel system drives the air flow which is ten times of the air flow sucked by the air channel system, so that the effect of uniform temperature is achieved.
2. The air flow direction in the air duct is controlled by changing the position of the fan blades of the electric air door, so that the phenomenon that the fan is easy to resonate with peripheral refrigerator parts during operation is reduced, and the noise is reduced.
3. And one air power device is adopted to drive a plurality of compartments to refrigerate, so that the cost is low.
