[0030] See Figures 1-3 The utility model provides a freezing chamber structure 100 is by box body 10 and air duct board 20 is composed, and the both sides are connected through the matching of positioning convex 23 and positioning groove 111, and the convenient assembly is not easy to cause the box body 10 breakage because of the existence of the hook structure.
[0031] The freezing chamber structure 100 includes a box body 10 and an air duct plate 20. The box body 10 has a cavity 13. The air duct plate 20 is located in the cavity 13 and connected with the box body 10. The box body 10 is provided with a positioning groove 111 on the inner wall of the cavity 13. The air duct plate 20 is provided with a positioning convex 23. The positioning convex 23 is in a circular arc structure. The top end of the positioning convex 23 away from the air duct plate 20 is provided with an abutting plane 231. The abutting plane 231 abuts with the groove bottom of the positioning groove 111. In this way, the positioning convex 23 and the positioning groove 111 can be connected and positioned, which can assist the assembly of the freezing chamber structure 100. Because the part of the positioning convex 23 abutting with the groove bottom of the positioning groove 111 is provided with the abutting plane 231, the abutting effect of the positioning convex 23 and the positioning groove 111 is more stable, which makes the structure of the freezing chamber structure 100 more stable.
[0032] Further, the height of the positioning convex 23 is the same as the depth of the positioning groove 111. The depth X of the positioning groove 111 satisfies 3.5mm≤X≤4.5mm. In this way, the matching depth of the positioning convex 23 and the positioning groove 111 is reasonably set. The height of the positioning convex 23 can ensure the connection strength, and can avoid the problem of difficult assembly caused by the positioning convex being too high.
[0033] Exemplarily, the depth of the positioning groove 111 is set to 3.5mm, 4mm or 4.5mm, which is not limited to the two end values mentioned above.
[0034] Because the positioning convex 23 is in a circular arc structure, the outer periphery side of the positioning convex 23 is provided with a round corner. The round corner of the outer periphery side of the positioning convex 23 is R, which satisfies 3mm≤R≤5mm. In this way, the matching and abutting limiting strength of the positioning convex 23 and the groove wall of the positioning groove 111 is enough for the stable connection of the box body 10 and the air duct plate 20. The round corner of the outer periphery side of the positioning convex 23 can smoothly guide the positioning convex 23 into the positioning groove 111 without interference.
[0035] Exemplarily, the round angle is set as 3mm, 3.5mm, 4mm, 4.5mm or 5mm, etc., without being limited to the two end values mentioned above.
[0036] The abutting plane 231 is set as a circular arc shape, and the radius r of the abutting plane 231 satisfies 1mm≤r≤3mm. In this way, the area of the abutting plane 231 can be ensured to be sufficient to provide the abutting support effect, and it will not be too large to affect the setting of the round angle mentioned above.
[0037] Exemplarily, the radius r of the abutting plane 231 is set as 1mm, 1.5mm, 2mm, 2.5mm or 3mm, etc., without being limited to the two end values mentioned above.
[0038] Further, the positioning protrusions 23 are provided in plurality and are respectively connected to the two sides in the width direction of the air duct plate 20, and the inner wall of the cabinet 10 forming the chamber 13 is provided with a plurality of positioning grooves 111, and the positioning grooves 111 are provided in one-to-one correspondence with the positioning protrusions 23. In this way, the cooperation of the plurality of positioning protrusions 23 and the positioning grooves 111 further improves the connection strength between the air duct plate 20 and the cabinet 10.
[0039] Further, along the length direction of the air duct plate 20, the positioning protrusions 23 located on the same side are uniformly arranged at intervals. In this way, the air duct plate 20 can be more balanced when it is pushed or pulled by wind when the freezing chamber structure 100 is in the air inlet state, so as to improve its durability.
[0040] Preferably, referring to Figures 4-6 , the air duct plate 20 comprises a main body part 21 and a mounting part 22, the mounting part 22 is connected to the two sides in the width direction of the main body part 21 and is arranged at an angle with the main body part 21, and the positioning protrusions 23 are connected to the mounting part 22. In this way, the processing of the positioning protrusions 23 is facilitated, and the mounting part 22 can also improve the torsional strength of the main body part 21.
[0041] In the present embodiment, the main body part 21 and the mounting part 22 are arranged perpendicularly.
[0042] The mounting part 22 is provided with at least two spaced apart grooves 221, the grooves 221 are arranged along the extension direction of the mounting part 22, and the positioning protrusions 23 are connected to the mounting part 22 between the two grooves 221, and at least one reinforcing rib 222 is arranged on the side of the mounting part 22 away from the positioning protrusions 23, and the reinforcing rib 222 is connected with the main body part 21. In this way, the elasticity of the mounting part 22 between the two grooves 221 will be strengthened due to the existence of the grooves 221, so that the positioning protrusions 23 can be displaced to avoid during assembly, so as to facilitate assembly into the cabinet 10.
[0043] Preferably, the reinforcing ribs 222 are two and are arranged at intervals to further improve the structural strength.
[0044] The box body 10 comprises side plates 11 and a back plate 12, the side plates 11 and the back plate 12 are connected and form a cavity 13, a positioning groove 111 is arranged on the side plate 11, and the air duct plate 20 is arranged at intervals with the back plate 12 and forms an air duct for air passing through.
