[0015] In one embodiment, the plurality of placing tables are independently arranged.

[0016] When the placing table bears the target object, the placing table is compressed and triggers the corresponding detection sensor.

[0021] In one embodiment, the bellows can be inserted and matched with the air outlet pipe joint, and the bellows and the air outlet pipe joint are fixed by a clamp.

[0038] The thawing device 100 claimed in the present application, particularly a thawing device applied to a refrigerator, is used for thawing a target object (not shown in the figure). Here, the target object is particularly food obtained after being frozen by the refrigerator. Of course, the thawing device 100 can also be used as an independent refrigeration chamber of the refrigerator in the refrigerator, which will not be described here.

[0039] As Figures 1 to 3As shown, the thawing device 100 provided by the present application comprises a drawer 10, a plurality of detection sensors (not shown in the figure) and a thawing module 20. The drawer 10 has a support plate 11 comprising a plurality of placement tables 111 for carrying target objects. The plurality of detection sensors are installed on the drawer 10 and correspond to the plurality of placement tables 111 one by one. The detection sensors can detect the target objects on the corresponding placement tables 111 and generate feedback signals. The thawing module 20 is arranged directly above the support plate 11. The thawing module 20 comprises an air outlet pipe joint 21 and a translation mechanism 22. The air outlet pipe joint 21 is installed on the translation mechanism 22. The translation mechanism 22 can control the translation of the air outlet pipe joint 21 relative to the support plate 11 according to the feedback signals, so that the air outlet 211 of the air outlet pipe joint 21 is arranged directly above the target object. Here, the thawing device 100 further comprises a controller (not shown in the figure). The controller is electrically connected to the translation mechanism 22 and the plurality of detection sensors, respectively. The controller receives and processes the feedback signals transmitted by the detection sensors, and then sends control signals to the translation mechanism 22 to control the movement of the air outlet pipe joint 21 driven by the translation mechanism 22.

[0040] As can be seen from the above, when the thawing device 100 works, the feedback signals generated by the detection sensors can be used to determine the placement table 111 on which the target object is placed in the drawer 10. The position of the air outlet 211 of the air outlet pipe joint 21 is adjusted accordingly, so that the air outlet pipe joint 21 can directly blow to the target object on the placement table 111. In this way, the air outlet distance is shortened, and the wind speed of the air directly blowing to the target object is increased, thereby improving the thawing efficiency of the thawing device 100 when it works.

[0041] It should be noted that when the user places the target object on the support plate 11 of the drawer 10, the drawer 10 can use one placement table 111 to carry the target object, or use a plurality of placement tables 111 to jointly carry the target object. The specific placement position of the target object on the support plate 11 can be determined according to the size of each placement table 111 in the drawer 10 and the size of the target object when it contacts the support plate 11.

[0042] When one placement table 111 carries the target object, only one detection sensor corresponding to the placement table 111 is triggered and generates a feedback signal in the thawing device 100. At this time, the controller in the thawing module 20 can control the translation mechanism 22 to drive the air outlet pipe joint 21 to translate to the position directly above the placement table 111 after receiving the feedback signal transmitted by the detection sensor. Here, the center of the air outlet 211 of the air outlet pipe joint 21 is arranged to align with the center of the placement table 111.

[0043] When the multiple placement tables 111 jointly bear the target object, the multiple detection sensors corresponding to the multiple placement tables 111 in the thawing device 100 can be triggered and generate feedback signals, at this time, the controller in the thawing device 100 can roughly judge the specific position of the target object on the support plate 11 by analyzing the multiple feedback signals after receiving the feedback signals transmitted by the multiple detection sensors, and then the controller can control the translation mechanism 22 to drive the air outlet pipe joint 21 to translate to the upper side of the placement table 111. Here, the center of the air outlet 211 of the air outlet pipe joint 21 is aligned with the center of the position of the target object calculated by the controller.

[0044] As shown in the drawings, Figure 2 In an embodiment, the multiple placement tables 111 are connected as a whole, that is, the multiple placement tables 111 can be divided by the support plate 11; when the placement table 111 bears the target object, the placement table 111 is pressed and elastically deformed, and the detection sensor can detect the elastic deformation of the corresponding placement table 111 and generate a feedback signal. That is, the thawing device 100 of this embodiment can determine the position of the target object when placed in the drawer 10 by detecting whether the placement table 111 is elastically deformed, which can simplify the structure of the support plate 11, thereby facilitating the production of the drawer 10. Here, the support plate 11 can be configured as a spring or a plastic plate.

[0045] In this embodiment, the detection sensor is configured as a capacitive sensor, so that the thawing device 100 can use the capacitive sensor to detect the distance change caused by the deformation of the placement table 111, which can improve the detection sensitivity of the detection sensor when detecting the deformation of the placement table 111. Here, the capacitive sensor can be arranged at a position below the support plate 11.

[0046] As shown in the drawings, Figure 2 In an embodiment, the multiple placement tables 111 are independently arranged; when the placement table 111 bears the target object, the placement table 111 is pressed and triggers the corresponding detection sensor. Here, the detection sensor is configured as a pressure sensor.

[0047] As shown in the drawings, Figure 1 , Figure 3 In an embodiment, the translation mechanism 22 is configured as an XY-axis translation platform, which utilizes the structural characteristics of the XY-axis translation platform to enable the translation mechanism 22 to drive the air outlet pipe joint 21 to be adjusted arbitrarily in the plane direction when working, which can satisfy the air outlet pipe joint 21 being able to be translated to the upper side of the target object on the support plate 11 under the driving of the translation mechanism 22. Here, the XY-axis translation platform can realize two-dimensional positioning in the plane through two mutually perpendicular linear motion mechanisms (usually motor-driven screw-nut pairs), which will not be described here.

[0048] like Figure 4 As shown, in one embodiment, the defrosting module 20 further includes a corrugated pipe 23, which is connected to and communicates with the air outlet connector 21 to provide airflow to the air outlet connector 21. During the translation process of the translation mechanism 22 driving the air outlet connector 21, the corrugated pipe 23, utilizing its structural characteristics, deforms along with the movement of the air outlet connector 21, allowing it to continuously provide airflow to the air outlet connector 21 unaffected by the translation of the air outlet connector 21. It should be noted that when the defrosting device 100 is applied in a refrigerator, the end of the corrugated pipe 23 furthest from the air outlet connector 21 can be connected to the refrigerator's refrigeration air duct.

[0049] like Figure 4 As shown, in this embodiment, the corrugated pipe 23 can be inserted into the air outlet duct connector 21, and the corrugated pipe 23 and the air outlet duct connector 21 are fixed together by a clamp 231. That is, when assembling the corrugated pipe 23 with the air outlet duct connector 21, the corrugated pipe 23 can be inserted into the air outlet duct connector 21 first, and then the clamp 231 can be used to limit the assembly of the two. This facilitates the assembly and connection between the corrugated pipe 23 and the air outlet duct connector 21 and ensures the stability of the connection between the two.

[0050] like Figure 1 As shown, in one embodiment, the defrosting device 100 further includes a drawer cover 30, which closes onto the drawer 10; wherein, the defrosting module 20 is mounted on the drawer cover 30. That is, the defrosting device 100 uses the drawer cover 30 to support the defrosting module 20, so that the drawer cover 30 can also block the airflow blowing towards the target object, thus preventing airflow loss during defrosting and further improving the defrosting efficiency of the defrosting device 100. Here, the translation mechanism 22 in the defrosting module 20 can be fixed to the side of the drawer cover 30 facing the drawer 10 support plate 11 via a connecting bracket.

[0051] In addition, this application also provides a refrigerator, including the defrosting device 100 described above.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation to the present application, and as long as the above embodiments are made within the scope of the present application, the appropriate changes and variations of the above embodiments fall within the scope of the present application.
