Referring to fig. 1 and 2, the air-out controllable refrigeration cabinet according to the present invention includes a cabinet 11 and a door 12 disposed at a front side of the cabinet 11 for opening or closing the cabinet 11. An accommodating chamber 110 for accommodating articles is formed in the case 11. The refrigeration cabinet of the present invention further includes a shelf 400 transversely disposed in the accommodating cavity 110 for dividing the accommodating cavity 110, and specifically, in this embodiment, three shelves 400 are disposed at intervals from top to bottom, and four layers of divided spaces are formed in the accommodating cavity 110.
Further, the box 12 of the present invention further has an air outlet duct 200 extending from bottom to top for allowing the air cooled by the evaporator 500 to enter the accommodating cavity 110. In the present embodiment, the air outlet duct 200 extends from the bottom to the top and is located at the rear side of the accommodating cavity 110, and is formed by an air duct cover plate 112 located at the rear side of the accommodating cavity 110 and a first back plate 111 located at the rear side of the air duct cover plate 112.
In the present invention, at least one shelf 400 is located within the height range of the air outlet duct 200, and as shown in fig. 2, in this embodiment, two upper three shelves 400 are located within the height range of the air outlet duct 200, and one lower shelf 400 is located below the air outlet duct 200. As shown in fig. 2, 4 and 5, a first channel 41 communicated with a lower space of each shelf 400 located within the height range of the air outlet duct 200 is formed in each shelf 400, and as shown in fig. 11, the air outlet duct 200 has a first air outlet 21 butted with the first channel 41. Specifically, in the present embodiment, the first air outlet 21 includes a top shelf air outlet 211 and a middle shelf air outlet 212 respectively connected to the first channels 41 in the two shelves 400 at the upper side.
As a preferred embodiment, the refrigerator according to the present invention further comprises a first damper 411 having an opening degree adjusted to control the amount of cooling air entering the first channel 41 from the outlet duct 200, a sensing unit (not shown) for sensing the storage amount of the articles in the space under the corresponding shelf 400, and a first control unit (not shown) for controlling the opening degree of the damper according to the sensing signal of the sensing unit; wherein, when the sensing unit senses that the storage amount of the goods in the space under the corresponding shelf 400 is increased, the opening degree of the first damper 411 is increased.
Based on the design of first air door 411, during the freezer work, the cold tolerance that gets into in the partition space by air-out wind channel 200 can be adjusted according to the article storage capacity in the corresponding partition space, so make the distribution of air conditioning more reasonable, improve the refrigeration efficiency of refrigeration cabinet.
In an implementation process, the sensing unit is a pressure sensor disposed at the bottom of the space under the corresponding shelf 400 for sensing the weight of the stored goods in the space.
In this embodiment, the air duct cover plate 112 forms a rear wall of the accommodating cavity 110, the first air outlet 21 is formed on the air duct cover plate 112, the first channel 41 extends in the front-rear direction, and the rear end of the first channel is connected to the first air outlet 21, and a plurality of first through holes 410 for communicating the first channel 41 with the space below the shelf 400 are formed on the lower surface of the shelf 400; the opening area ratio of the plurality of first through holes 41 on the lower surface of the shelf 400 is gradually increased in a direction in which the rear end of the first passage 41 is directed toward the front end.
When the refrigerator is operated, the air outlet duct 200 can discharge cold air to the positive pressure of the accommodating cavity 110, after the first air door 411 is opened, the positive pressure intensity in the first through hole 410 close to the first air outlet 21 is greater than the positive pressure intensity in the first through hole 410 far away from the first air outlet 21, based on the arrangement mode of the first through hole 410 on the lower surface of the partition board 400 in the embodiment, the cold air supply speed in the lower space of the partition board 400 at different positions can be consistent as far as possible, so that the refrigerating effect can be more uniform at different positions in the lower space of the partition board 400.
As shown in fig. 1 and 3, the cabinet 11 of the refrigeration cabinet of the present invention further includes a return air duct 300 for returning air inside the accommodating cavity 110 to the evaporator 500 for cooling. Specifically, in the present embodiment, the return air duct 300 extends from top to bottom and is located in the middle of the rear side of the accommodating cavity 110, and is formed by the duct cover plate 112 located at the rear side of the accommodating cavity 110 and the second back plate 113 located at the rear side of the duct cover plate 112.

Referring to fig. 9, the refrigeration cabinet of the present invention further includes a second damper 421 which is opened or closed to control whether the return air duct 300 is communicated with the second duct 42, a freshness degree sensing unit 422 for sensing freshness degree data of the articles in the space above the corresponding shelf 400, a determining unit (not shown) for determining whether the articles in the space above the corresponding shelf 400 are fresh or not according to a sensing signal of the freshness degree sensing unit 422, and a second control unit (not shown) for controlling the second damper 421 to be opened or closed according to a determination result of the determining unit. Wherein, when the judging unit judges that the articles in the upper space of the corresponding shelf 400 are fresh, the second air door 421 is opened.
Based on the specific structure of the controllable air-out refrigeration cabinet, when the articles on a certain shelf 400 are not fresh, the fluidity of the air in the space above the shelf 421 can be reduced by closing the second air door 421 corresponding to the shelf 400, so that the cross contamination among a plurality of partitioned spaces in the accommodating cavity 110 can be avoided, and the refrigeration effect of the refrigeration cabinet is improved.
It is understood that, in the implementation process, a certain gap may exist between the front end of each shelf 400 and the door body 12, that is, during the operation of the refrigerator, a certain exchange may exist between the air in the spaces above and below each shelf 400. However, relatively speaking, most of the air in the space above each shelf 400 mainly flows back to the return air duct 300 through the second channel 42 of the corresponding partition 400, and further flows to the evaporator 500 to realize cooling; when a certain second damper 421 is closed, the air fluidity in the space above the corresponding shelf 400 is greatly reduced.
In this embodiment, the freshness sensing unit is an odor sensor, which can be used to detect the gas generated after the articles are spoiled. In the specific implementation process, a reference threshold value is preset in the judgment unit, when the gas concentration detected by the odor sensor does not exceed the reference threshold value, the second air door 421 keeps an open state, and air in the upper space of the corresponding shelf 400 can flow back to the return air duct 300 through the second channel 42; when the gas concentration detected by the odor sensor exceeds the threshold value, the second control unit controls the second damper 421 to close the first air return opening 31, and the air in the space above the corresponding shelf 400 cannot flow back to the air return duct 300 through the second channel 42.
As a preferred embodiment of the present invention, the refrigeration cabinet further comprises an alarm unit (not shown in the figure) for automatically alarming when the judging unit judges that the articles in the space above the corresponding shelf 400 are not fresh, wherein the alarm unit may be a buzzer, an indicator light, a display screen, or other components capable of providing sound signals or visual signals to the user. Referring to fig. 3, in the embodiment, the air duct cover plate 112 forms a rear wall of the accommodating cavity 110, and the first air return opening 31 is formed on the air duct cover plate 112. Referring to fig. 4 and 9, in the present embodiment, the second channel 42 extends in the front-rear direction and the rear end of the second channel is connected to the first air return opening 31, and a plurality of second through holes 420 communicating the second channel 42 with the space on the shelf 400 are formed on the upper surface of the shelf 400.
As a preferred embodiment of the present embodiment, in a direction in which the rear end of the second channel 42 is directed to the front end, the ratio of the opening area of the plurality of second through holes 420 on the upper surface of the shelf 400 gradually increases. When the refrigerator runs, negative pressure can be generated in the return air duct 300, after the second air door 421 is opened, the negative pressure intensity in the second through hole 420 close to the first return air opening 31 is greater than the negative pressure intensity in the second through hole 420 far away from the first return air opening 31, based on the arrangement mode of the second through hole 420 on the upper surface of the partition board 400 in the embodiment, the air return speed in different positions in the front and at the back in the space on the upper side of the partition board 400 can be consistent as much as possible, so that a more uniform refrigeration effect can be realized in different positions in the front and at the back in the space on the upper side of the partition board 400.
In the present invention, the arrangement of the second through holes 420 on the upper surface of the partition 400 may be implemented by various specific implementation structures. It is understood that the specific design of the first through hole 410 may refer to the design of the second through hole 410.
Referring to fig. 4, which shows a first specific implementation of the arrangement of the second through holes 420 on the upper surface of the partition 400, in the present embodiment, the opening area of a single second through hole 420 is gradually increased in a direction from the rear end to the front end of the second channel 42. More specifically, the plurality of second through holes 420 are arranged at equal intervals, and the opening area of a single second through hole 420 far away from the first air return opening 31 is larger than the opening area of a single second through hole 420 near the first air return opening 31.
Referring to fig. 10, a second specific implementation of the arrangement of the second through holes 420 on the upper surface of the partition board 400 is shown, in this embodiment, the opening area of each second through hole 420 on the upper surface of the partition board 400 is the same, but the density of the second through holes 420 is gradually increased in the extending direction of the second channel 42. In this embodiment, the second through holes 420 are preferably formed as fine holes, and the maximum dimension in the front-rear and left-right directions is controlled to be within 3mm, for example, so that particles on the upper surface of the separator 400 can be prevented from falling into the second channel 42.

However, as a preferred embodiment of the present invention, referring to fig. 6, the shelf 400 of the present embodiment has a lower region formed with the second through holes 420 and having a level not higher than the peripheral region thereof on the upper surface thereof, and the height of the peripheral region of the lower region is gradually decreased in a direction approaching the lower region. In the embodiment shown in fig. 6, the lower area is a middle area of the upper surface of the partition board 400, and the accumulated water on the upper surface of the partition board 400 can be guided into the second passage 42 through the second through hole 420 based on the design manner of the peripheral area of the lower area. In the specific implementation process, the accumulated water entering the second channel 42 can be further guided into the water receiving tank through the return air duct 300 or directly guided out of the box body 11.
As some preferred embodiments of the present invention, the height of the bottom surface of the inner wall surrounding the second channel 42 is gradually decreased in the direction close to the first air return opening 31, that is, the bottom surface of the inner wall surrounding the second channel 42 forms a slope for the water to automatically flow toward the first air return opening 31. Referring to fig. 7 and 8, two different cross-sectional views of the partition 400 in the extending direction of the second channel 42 are shown, wherein the lower surface of the partition 400 is parallel to the horizontal plane in the implementation structure shown in fig. 7, and the lower surface of the partition 400 is parallel to the bottom surface of the inner wall surrounding the second channel 42 in the implementation structure shown in fig. 8.
