In the present invention, unless clear and definite regulation and restriction are arranged in addition, broad understanding should be done in the terms such as term " installation ", " linking to each other ", " connection ", " fixing ", for example, can be to be fixedly connected with, and also can be to removably connect, or connect integratedly; Can be directly to link to each other, also can indirectly link to each other by intermediary, can be the connection of two element internals.For the ordinary skill in the art, can understand as the case may be above-mentioned term concrete meaning in the present invention.
Below with reference to the axial-flow blower 20 of Fig. 2 description according to the embodiment of the invention.As shown in Figure 2, the axial-flow blower 20 according to the embodiment of the invention comprises rotating shaft 21 and a plurality of flabellum 22.A plurality of flabellums 22 asymmetricly are located in the rotating shaft 21.
Distance between two adjacent flabellums 22 and the end that rotating shaft 21 links to each other is the flabellum spacing.A plurality of flabellums 22 asymmetricly are located at least one the flabellum spacing that refers in the rotating shaft 21 according to the axial-flow blower 20 of the embodiment of the invention and are not equal to other flabellum spacing.
A plurality of flabellums of existing axial-flow blower are symmetrical arranged with respect to spindle central.In existing axial-flow blower rotation process, the vibration frequency that each flabellum and air friction produce is consistent, thereby the noise that each flabellum produces superposes mutually, so that the noise of existing axial-flow blower is very large.And according to the axial-flow blower 20 of the embodiment of the invention by a plurality of flabellums 22 asymmetricly are located in the rotating shaft 21, thereby when rotating, can make each flabellum 22 different with the vibration frequency of air friction generation.The noise that produces of each flabellum 22 will be distributed in different frequency bands thus, so the noise that each flabellum 22 produces can not superpose mutually, and the noise of axial-flow blower 20 generations is lower like this.Therefore, the axial-flow blower 20 according to the embodiment of the invention has advantages of that noise hangs down etc.
Advantageously, the spacing of adjacent two flabellums 22 of axial-flow blower 20 can be unequal each other.The spacing of adjacent two flabellums 22 refers to the distance (being the flabellum spacing) between adjacent two flabellums 22 and the end that rotating shaft 21 links to each other.Axial-flow blower 20 according to the embodiment of the invention has a plurality of flabellums 22, therefore has a plurality of flabellum spacings.Wherein, the spacing of adjacent two flabellums 22 each other unequal each flabellum spacing that refers to be not equal to other flabellum spacing.Can further reduce thus the noise that axial-flow blower 20 produces.
Below with reference to the refrigerator 1 of Fig. 1 description according to the embodiment of the invention.As shown in Figure 1, the refrigerator 1 according to the embodiment of the invention comprises casing 10, door body (not shown) and axial-flow blower.
Have chamber 11 between refrigeration in the casing 10, described door body is installed on the casing 10 in order to open and close chamber 11 between refrigeration.Described axial-flow blower is the axial-flow blower 20 according to above-described embodiment.Axial-flow blower 20 is located between refrigeration in the chamber 11.
According to the refrigerator 1 of the embodiment of the invention by the axial-flow blower 20 according to above-described embodiment is set, thereby have the advantages such as noise is low.According to the sealing of the casing of the refrigerator 1 of the embodiment of the invention preferably in the situation, even if night the user also can't hear the noise that cross flow fan 20 produces.
Alternatively, refrigerator 1 can also comprise the air duct cover board (not shown), and described air duct cover board can be located between refrigeration in the chamber 11, described air duct cover board can and refrigeration between limit the air channel between the wall of chamber 11.Can improve thus the refrigerating efficiency of refrigerator 1, not only can make the temperature in the chamber between refrigeration 11 more even, and can make that the temperature in the chamber 11 reach predetermined value more rapidly between refrigeration.
Particularly, described air duct cover board limits described air channel between the rear wall of chamber 11 between can and freeze.Refrigerator 1 has advantages of simple in structure thus.Refrigerator 1 can be wind cooling refrigerator.
In one embodiment of the invention, axial-flow blower 20 can be located at outside the described air channel and the intake grill in contiguous described air channel and exhaust outlet in one.Axial-flow blower 20 can also be located in the described air channel and in the intake grill in contiguous described air channel and the exhaust outlet.Not only can increase thus the storage space of chamber 11 between refrigeration, make the structure of chamber 11 between refrigeration more succinct, and can accelerate cold wind chamber 11 interior circulations between refrigeration.
Particularly, chamber 11 can be cold storage room between refrigeration.Axial-flow blower 20 can be close to the roof of chamber 11 between refrigeration and rear wall (as shown in Figure 1, roof refer to the to freeze upper wall of a chamber 11, above-below direction is shown in the arrow A among Fig. 1).
In an example of the present invention, chamber 11 can be a plurality of and axial-flow blower 20 also can be a plurality of between refrigeration, and a plurality of axial-flow blowers 20 are located at respectively between a plurality of refrigeration in the chamber 11 accordingly.In other words, axial-flow blower 20 is located between a refrigeration in the chamber 11.
In the description of this specification, the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or the example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiments or example.
