Detailed description of the invention
Fig. 1 is the schematic diagram of refrigerator according to an embodiment of the invention, and Fig. 2 is the schematic, exploded of refrigerator according to an embodiment of the invention.As depicted in figs. 1 and 2, embodiments provide a kind of refrigerator, it can comprise casing 500 and door body.Can be limited with room 510 between the storing for storing articles in casing 500, room 510 between this storing is opened or closed in the front side that door body can be used for room 510 between storing.Between this storing, room 510 also can be separated into multiple storage space by board putting things/rack 520.In embodiments of the present invention, multiple separate supply air duct 530 is also limited with in casing 500, multiple supply air duct 530 can be configured to respectively by multiple At The Heights of room 510 between pneumatic convey to storing, with multiple storage space in room 510 between this storing or multiple At The Height transporting cold-air stream.Further, when the cold of certain storage space or a certain At The Height is not enough in room 510 when between this storing, only can open the supply air duct 530 being sent to this At The Height, with to this At The Height transporting cold-air stream.
In embodiments of the present invention, at least part of supply air duct 530 can only to the horizontal side delivery air of a certain At The Height in room 510 between this storing, the reason producing this phenomenon is, if this supply air duct 530 can simultaneously to the both lateral sides delivery air of a certain At The Height in room 510 between storing time, this supply air duct 530 may intersect with other supply air duct 530 and be communicated with, make between multiple supply air duct 530 not separate, such as, in the perpendicular that multiple supply air duct 530 rear surface of being in room 510 between with storing is parallel.Therefore, in the present embodiment, inventor can only be called the first supply air duct 531 to the supply air duct 530 of horizontal side, room between storing 510 delivery air, that is, multiple supply air duct 530 comprises at least one first supply air duct 531, and each first supply air duct 531 is configured to the horizontal side of an At The Height of room 510 between pneumatic convey in it to storing.Because each first supply air duct 531 can only, by the horizontal side at the corresponding height place of room 510 between pneumatic convey to this storing, make the both sides of this At The Height of room 510 between storing catch a cold even not.In order to solve this kind of problem, inventors herein propose following technical scheme.
The refrigerator of the embodiment of the present invention also can comprise at least one bridge joint air channel 540, each bridge joint air channel 540 is communicated to first supply air duct 531, and be configured to by room 510 between the pneumatic convey in this first supply air duct 531 to storing, the horizontal opposite side of At The Height that pneumatic convey in it arrives by this first supply air duct 531.This refrigerator makes the air-flow of the first supply air duct 531 enter room 510 between this storing from the both lateral sides of room 510 between storing by bridge joint air channel 540 simultaneously, even as much as possible to make the both sides at corresponding height place, room 510 between storing catch a cold.
In addition, catch a cold as far as possible evenly to make the both sides at differing heights place, room 510 between storing, the quantity that inventor proposes towards the first supply air duct 531 of each At The Height is the technical scheme of two, be communicated to the both lateral sides of this At The Height respectively, but this kind is arranged relative to the scheme with bridge joint air channel 540, complex structure, and need to control two the first supply air ducts 531 towards this At The Height, control more complicated. simultaneouslyTherefore, bridge joint air channel 540 the makes both sides at differing heights place in room 510 between storing catch a cold as far as possible uniform scheme that what the present invention proposed utilize, the compact conformation of refrigerator can be made, control simple.
In some embodiments of the invention, also existing in multiple supply air duct 530 can simultaneously to the supply air duct 530 of the both lateral sides delivery air of refrigerator, be referred to as the second supply air duct 532, be configured to the both lateral sides of an At The Height of room 510 between the pneumatic convey in it to storing.Such as, as shown in Figure 1, the air inlet 21 of each supply air duct 530 is all lower than its air outlet 22.Second supply air duct 532 by pneumatic convey in it to At The Height above the At The Height that the pneumatic convey in it arrives by each first supply air duct 531, and the first supply air duct 531 is multiple, part first supply air duct 531 is positioned at the side of the second supply air duct 532, and all the other the first supply air ducts 531 are positioned at the opposite side of the second supply air duct 532.Such setting, when can make the second supply air duct 532 to the both lateral sides delivery air of room 510 between storing, all with other not there is the possibility of intersecting in arbitrary supply air duct 530 (i.e. each first supply air duct 531), like this, bridge joint air channel 540 can not be adopted directly to the both lateral sides delivery air of refrigerator, that is, the second supply air duct 532 can be configured to the both lateral sides of an At The Height of room 510 between the pneumatic convey in it to storing.
Further, in some embodiments, between the storing limited in casing 500, room 510 is refrigerating chamber.Between this storing, room 510 also can be separated into multiple storage space by board putting things/rack 520, and e.g., room 510 between this storing is divided into four storage spaces vertically arranged by three board putting things/racks 520.The quantity of the first supply air duct 531 can be two, and a side being arranged on the second supply air duct 532, another is arranged on the opposite side of the second supply air duct 532.Second supply air duct 532 can to delivery air in uppermost storage space, the first supply air duct 531 being positioned at the second supply air duct 532 side can be top to centre storage space delivery air, be positioned at the second supply air duct 532 opposite side the first supply air duct 531 can to centre storage space delivery air on the lower.Nethermost storage space can utilize the cold air in three storage spaces above.In Fig. 1, arrow can represent the flow direction of air-flow, now, air-flow all can be had in three supply air ducts 530 to flow through.
In embodiments of the present invention, between storing, an At The Height of room 510 can refer to one highly in interval.Such as, the second supply air duct 532 can have four air outlets, is symmetrical arranged about the vertical central plane of room 510 between this storing.Each first supply air duct 531 has an air outlet, lay respectively at the horizontal side at the corresponding height place of room 510 between storing, the air outlet in each bridge joint air channel 540 is positioned at the horizontal opposite side of corresponding At The Height, and the air outlet in each first supply air duct 531 and corresponding bridge joint air channel 540 can be symmetrical arranged about the vertical central plane of room 510 between this storing.
In some embodiments of the invention, in casing 500, be also limited with total air channel 550, be configured to receive cold airflow and carry in multiple supply air duct 530.Such as, also can be limited with distribution cavity 560 in casing 500, total air channel 550 can be communicated with multiple supply air duct 530 via distribution cavity 560.
For the ease of controlling the air quantity/break-make of each supply air duct 530, refrigerator also can comprise air-supply arrangement 600 along separate routes further, can be installed in distribution cavity 560, be configured to controllably regulate the air quantity in multiple supply air duct 530.When making the air quantity in a certain supply air duct 530 be 0, can be regarded as this supply air duct and being in off-state.Such as, in certain embodiments of the present invention, air-supply arrangement 600 can comprise the by-pass valve control be arranged in each supply air duct 530, to control each supply air duct 530 respectively along separate routes.
