Refrigeration air duct assembly capable of regulating air quantity and refrigerator

Abstract

The invention provides a refrigeration air duct assembly capable of regulating the air quantity and a refrigerator. The refrigeration air duct assembly comprises a rotary knob support, a refrigerationair duct cover plate, refrigeration air duct foam and a threaded rod air door. The rotary knob support is connected with the threaded rod air door. The refrigeration air duct foam is arranged betweenthe rotary knob support and the threaded rod air door. An external thread is arranged on the threaded rod air duct. An internal thread is arranged on the refrigeration air duct cover plate. The threaded rod air door is connected with the refrigeration air duct cover plate in a rotating manner through the internal thread and external thread structure so that the threaded rod air duct can move in the axial direction of the threads while rotating along the threads relative to the refrigeration air duct cover plate. Front-back axial movement of the threaded rod air duct is achieved by making a rotary knob rotate through optimized application of the thread structure so that the size of an air opening can be regulated and the function of regulating the air quantity can be achieved. The regulation process is reasonable in stress and is smoother and more stable, the user experience is better, appearance is attractive, the assembly process is simple and reasonable, production operation and maintenance are convenient, and achievement is easy. The air duct volume is small, and the material cost is reduced.

[0002] With the improvement of living standards and the advancement of science and technology, people put forward higher requirements for refrigeration products such as refrigerators. Air-cooled frost-free refrigerators have become a trend for users to choose. Air-cooled refrigerators have various air duct structures and air volume adjustment functions. The methods are also different. The existing refrigerator refrigeration air duct adjustment air volume structure mainly has the following technical problems: no air volume adjustment function; relying on electric devices such as dampers to adjust the air volume, the implementation cost is high, and there is a greater risk of subsequent market problems; relying on ordinary paddles And other mechanical structures to adjust the air volume, the overall material cost of the air duct is high, and the user experience is poor, and the aesthetics are poor, etc.

[0003] Therefore, most of the existing adjustment methods are damper to adjust the air volume, and some adjustment methods such as the mechanical structure of the paddle, which still need to be further optimized in terms of production assembly, material cost, adjustment range, and user experience during the adjustment process.
