Problems solved by technology

However, in such a structure, the applicable air outlet area is small, resulting in a large pressure loss, and because it is a rotating structure, there is a gap between the rotating part and the housing, so the sealing performance is also poor

Embodiment approach 1

[0034] figure 1 It is an exploded perspective view showing the air blower 100 according to Embodiment 1 of the present invention, figure 2 It is a partially enlarged view of the air blower 100 .

[0035] Such as figure 1 , figure 2 As shown, the air blower 100 according to Embodiment 1 of the present invention includes a housing 10 and a fan 20 disposed in the housing 10 . The casing 10 includes a first support body 11 and a second support body 12 arranged opposite to each other, and has at least one air inlet 15 provided on the first support body 11 in a manner penetrating the first support body 11, and formed on the first support body 11. Between the support body 11 and the second support body 12, that is, a plurality of air outlets surrounded by the first support body 11 and the second support body 12 (such as the upper side air outlet 16 and the lower side air outlet described later) 17).

[0036] In addition, for example, the first support body 11 inside the housin...

Embodiment approach 2

[0057] Figure 8 It is a partial enlarged view showing the air blower according to Embodiment 2 of the present invention. The difference between the air blower of the second embodiment and the first embodiment is that the guide part 40 is not formed by a plurality of independent shaft parts, but is formed by two shafts located on the left and right sides of the upper shield part 31 and the lower shield part 32 . It consists of two plate members 45 and 46 .

[0058]The two plate-shaped members 45, 46 are arranged on the first support body 11 or the second support body 12 in a manner to stand upright with respect to the support surface of the first support body 11 or the second support body 12, and are positioned on the upper side to cover Between the ends of the portion 31 and the lower shielding portion 32 . The upper and lower end sides of the two plate-shaped members 45 and 46 are respectively engaged with both side end portions of the upper shielding portion 31 and the lo...

Abstract

The invention provides an air supply device and a refrigerator provided with the air supply device. The air supply device (100) comprises a shell (10), a fan (20), a plurality of shield parts (30) anda guide part (40), wherein the shell (10) is provided with at least one air inlet (15) and a plurality of air outlets (16 and 17), the fan (20) is arranged in the shell (10), sucks air through the air inlet (15), and exhausts air via the air outlets (16 and 17), shield parts (30) correspond to the air outlets (16 and 17) separately and are used for opening or closing the air outlets (16 and 17),the guide part (40) is fixed in the shell (10) and is used for supporting and guiding the shield parts (30), and the driving part (50) drives the shield parts (30) to move along the guide part (40) toopen and close the air outlets (16 and 17). According to the air supply device, the quantity of air supplied in each air supply channel can be properly adjusted.

Description

technical field [0001] The invention relates to an air supply device capable of adjusting the amount of air supplied to each air supply channel, and a refrigerator provided with the air supply device. Background technique [0002] In an existing refrigerator, a built-in evaporator generates cold air, and circulates the cold air through an air duct to each storage compartment of the refrigerator to realize cooling. However, if the air volume of the cold air is not adjusted and the cold air is allowed to flow randomly in the air duct, especially the freezer of many refrigerators is not provided with baffles for air volume adjustment, then when the refrigerator is cooled, the freezer will be cooled at the same time. The cooling makes the evaporating temperature lower, thereby reducing the efficiency of the refrigerator's cooling system. In addition, when defrosting is performed, heat may intrude into the compartment, and the temperature in the compartment may increase, leading...
