Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0062] The refrigeration device in the present application generally comprises a box body, a door body and a refrigeration system, wherein at least a refrigeration compartment is formed in the box body, and the refrigeration compartment is opened and closed through the door body to meet the requirements of storing and retrieving articles.

[0063] The refrigeration system uses a compressor, condenser, expansion valve and evaporator to perform the refrigeration cycle of the refrigeration equipment. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve cooling of the items in the box.

[0064] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0065] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can cool the items in the box by utilizing the latent heat of evaporation of the refrigerant.

[0066] Specifically, the present application proposes a refrigeration device, referring to Figure 1-Figure 3Specifically, a refrigerator is proposed, which includes a box body 100, and a refrigeration cavity is formed in the box body 100. The refrigeration cavity specifically includes a refrigerator chamber 101 and a freezer chamber 102, which are used for classified storage of items to be refrigerated or frozen.

[0067] Ports for introducing food are respectively provided at the front ends of the refrigerating chamber 101 and the freezing chamber 102. The refrigerating chamber 101 is used to insure food, and the freezing chamber 102 is used to freeze food. Doors are respectively hinged on the front sides of the refrigerating chamber 101 and the freezing chamber 102 for controlling the switch of the ports for introducing food.

[0068] The refrigerator is provided with an air flow channel 400 between the refrigerating chamber 101 and the freezing chamber 102. A fan component 200 is provided in the air flow channel 400 or in the freezing chamber 102. When the fan component 200 is turned on, the air flow in the freezing chamber 102 is driven to be transported to the refrigerating chamber 101 through the air flow channel 400.

[0069] A switch portion 430 is formed in the air flow channel 400 for controlling the opening and closing of the air flow channel 400 .

[0070] Since the freezer chamber 102 generates odor due to long-term storage of frozen food when in use, the odor is blown to the refrigerator chamber 101 along with the airflow under the action of the fan component 200 and diffuses in the refrigerator chamber 101, causing the user to have a bad experience when using the refrigerator chamber 101, and also causing pollution to other foods in the refrigerator chamber 101.

[0071] To solve the above problems, the present application provides an adsorption assembly and a sensor in the airflow channel 400 . The adsorption assembly includes at least two adsorption members 500 spaced apart in the airflow channel 400 along the flow direction of the airflow.

[0072] There are multiple sensors, which are respectively arranged at the input end and the output end of each adsorbent 500 , and are used to detect the components of the airflow before and after flowing through the corresponding adsorbent 500 .

[0073] That is, when the number of adsorbents 500 is n, the number of sensors is at least n+1.

[0074] The refrigeration device further includes a controller, which is connected inside the housing 100 and is connected to the sensor signals for determining the adsorption effect of each adsorption element 500 .

[0075] refer to Figure 3 , Figure 4Taking the example of two adsorbents 500 arranged at intervals in the airflow channel 400, the adsorbents 500 are sequentially arranged along the flow direction of the airflow, namely a first adsorbent 510 and a second adsorbent 520, a first sensor 610 is arranged upstream of the first adsorbent 510, a second sensor 620 is arranged between the first adsorbent 510 and the second adsorbent 520, and a third sensor 630 is arranged downstream of the second adsorbent 520.

[0076] The first sensor 610, the second sensor 620 and the third sensor 630 are respectively used to detect the airflow components at corresponding positions, specifically, to detect the odor in the airflow, and transmit the detection results to the controller.

[0077] The controller compares and analyzes the detection data of the first sensor 610 and the second sensor 620 and the detection data of the second sensor 620 and the third sensor 630 respectively.

[0078] When the difference in odor concentration between the first sensor 610 and the second sensor 620 is not less than the target difference, it indicates that the adsorption effect of the first adsorbent 510 is good. Otherwise, it indicates that the first adsorbent 510 needs to be replaced, and the controller sends a replacement signal to the user.

[0079] When the difference in odor concentration between the second sensor 620 and the third sensor 630 is not less than the target difference, it indicates that the adsorption effect of the second adsorbent 520 is good. Otherwise, it indicates that the second adsorbent 520 needs to be replaced, and the controller sends a replacement signal to the user.

[0080] For example, in some embodiments of the present application, a display screen may be provided on the door of the refrigerator, and the controller may prompt the user with a replacement signal of the corresponding adsorption component 500 through the display screen.

[0081] Specifically, the fan component 200 is disposed at the input end of the air flow channel 400 , and the fan component 200 is fixed on the rear wall of the freezing chamber 102 .

[0082] Specifically, a first inner liner 110 is formed in the refrigerating chamber 101 , a second inner liner 120 is formed in the freezing chamber 102 , and the fan component 200 is fixed on the rear wall of the second inner liner 120 .

[0083] refer to Figure 6 , Figure 7 In some embodiments of the present application, an air duct cover 300 is detachably connected to the rear wall of the first inner liner 110 , and the air flow channel 400 includes a connecting channel 410 and an air inlet channel 420 formed between the air duct cover 300 and the first inner liner 110 .

[0084] The connecting channel 410 is specifically a pipeline structure. The lower end of the connecting channel 410 extends into the freezing chamber 102 , and the upper end of the connecting channel 410 is connected to the air inlet channel 420 . The adsorption component and the sensor are arranged in the air inlet channel 420 .

[0085] Specifically, the air inlet channel 420 includes a first channel 421 and a second channel 422 . The first channel 421 is located upstream of the second channel 422 . The first channel 421 is directly connected to the output end of the connecting channel 410 .

[0086] In order to achieve smooth airflow, the width of the first channel 421 is equal to the width of the connecting channel 410. In order to increase the cooling effect of the airflow input into the refrigerating chamber 101, the second channel 422 gradually expands from bottom to top along the flow direction of the airflow.

[0087] The air duct cover plate 300 is formed with air outlets 310 , which are respectively located in the diversion channels 4221 . The air outlets 310 are used to connect the air inlet channel 420 and the refrigerating chamber 101 .

[0088] A diverter portion 330 is formed in the second channel 422, and diverter channels 4221 are formed on both sides of the diverter portion 330. The airflow is diverted into two parts by the diverter portion 330 and output from the air outlet 310 in the diverter channel 4221 to the refrigerator compartment 101 to increase the air outlet range.

[0089] Specifically, an air duct recess is formed on the inner side of the air duct cover 300 , and the air duct recess is a pressed shape extending toward the refrigerating chamber 101 . The diverter portion 330 is formed on the air duct recess, and the diverter portion 330 extends toward the rear wall of the first inner liner 110 .

[0090] A tapered guide tip 331 is formed at one end of the diversion portion 330 close to the first channel 421. When the airflow flows from the first channel 421 to the second channel 422, it is diverted to the diversion channels 4221 on both sides by the guide effect of the guide tip 331 and finally output from the air outlet 310.

[0091] The air duct cover plate 300 is provided with a mounting opening 320 , the mounting opening 320 corresponds to the position of the first channel 421 , and the adsorption member 500 is mounted on the corresponding mounting opening 320 .

[0092] After the switch part 430 is turned on, the fan in the freezing chamber 102 blows the low-temperature gas from the freezing chamber 102 into the air flow channel 400 , and then enters the refrigerating chamber 101 after passing through the adsorption component 500 in the air flow channel 400 .

[0093] When the damper is open, each sensor monitors the odor concentration.

[0094] When the adsorbent 500 works well, the odor concentration detected by the upstream and downstream corresponding sensors should be greatly reduced, and the ratio is large. When the ratio is less than the preset value, the controller reminds the user to replace the corresponding adsorbent 500.

[0095] Specifically, the adsorbent 500 includes an adsorbing portion 502 and a fixing portion 501 , and the adsorbing portion 502 is provided with materials such as activated carbon for adsorbing odor.

[0096] The fixing portion 501 is vertically disposed at one end of the adsorption portion 502 . The width of the adsorption portion 502 matches the width of the first channel 421 , so that all the gas passing through the first channel 421 is adsorbed by the adsorption portion 502 .

[0097] The adsorption portion 502 extends from the installation opening 320 into the first channel 421 , and the fixing portion 501 is fixedly connected to the air duct cover plate 300 .

[0098] The adsorption portion 502 can be tightly connected in the installation opening 320, or the fixing portion 501 can be snap-fitted to the installation opening 320.

[0099] In some embodiments of the present application, the width of the fixing portion 501 matches the width of the air duct cover plate 300 at the corresponding installation position.

[0100] Buckle portions 503 extending toward the adsorption portion 502 are formed on both sides of the fixing portion 501, and a snap-fit ​​portion 340 is provided on the side wall of the air duct cover 300. During installation, as the adsorption portion 502 is inserted into the inner side of the installation port 320, the buckle portion 503 is snapped onto the snap-fit ​​portion 340 at the corresponding position.

[0101] An installation guide surface is formed on the front side of the snap-fit ​​portion 340, and a mating surface is formed at the corresponding position of the snap-fit ​​portion 503. During the installation process, under the action of the installation guide surface and the mating surface, the snap-fit ​​portion 503 expands outward, and after passing through the snap-fit ​​surface, it retracts inward under the action of its own restoring force. The snap-fit ​​portion 340 is connected to the rear side of the snap-fit ​​portion 340 to achieve installation and fixation of the fixing portion 501.

[0102] During disassembly, the user pushes the buckle parts 503 on both sides outwards to remove the buckle parts 503 from the clamping parts 340 , thereby removing the adsorption part 502 for easy replacement.

[0103] In addition to the above-mentioned snap-fit ​​connection method, the fixing portion 501 can also be fixed to the air duct cover plate 300 by means of screws or the like.

[0104] In addition, reference Figure 8-Figure 11 In some embodiments of the present application, a drawer 700 is further provided in the freezer chamber 102 , and the drawer 700 is movably connected to the second inner container 120 via a guide rail assembly 800 .
