[0001] This application relates to the technical field of household appliances, and particularly to a refrigeration device. Background Art

[0002] Refrigeration devices usually have an air duct cover plate and an inner container. The air duct cover plate and the inner container define an air duct. A blower is arranged in the air duct. The air flow generated by the blower exchanges heat with the evaporator in the refrigeration device to form a cold air flow, and the cold air flow is discharged through the air outlet in the air duct to the storage compartment in the refrigeration device to achieve the refrigeration function.

[0003] There are many ways to connect the air duct cover plate and the inner container. The related art provides a connection method between the air duct cover plate and the inner container. The air duct cover plate is provided with a buckle, and the inner container is correspondingly provided with a groove. The buckle is inserted into the groove to fix the air duct cover plate to the inner container.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] When setting the groove in the inner container, at least part of the structure of the inner container needs to protrude in the direction away from the air duct cover plate to form a groove for inserting the buckle. When ensuring the optimal thickness of the foaming layer between the inner container and the outer shell, the protrusion of at least part of the structure of the inner container will occupy the storage space of the inner container and reduce the volume ratio of the refrigeration device.

These terms are mainly used to better describe the embodiments of the present disclosure and their embodiments, and are not used to limit that the indicated devices, elements or components must have a specific orientation, or be constructed and operated in a specific orientation. And, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0041] In addition, the terms "arranged", "connected", and "fixed" should be understood in a broad sense.

[0044] The term "and / or" is an associated relationship describing an object, indicating that there can be three relationships. For example, A and / or B means: A or B, or, the three relationships of A and B.

[0045] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0046] In a refrigeration device, usually a buckle is provided on the air duct cover plate, and a groove is correspondingly arranged on the inner liner. The buckle is clamped in the groove to connect the air duct cover plate and the inner liner. The groove is formed by at least part of the structure of the inner liner protruding in the direction away from the air duct cover plate. When ensuring the optimal thickness of the foam layer on the back of the box body of the refrigeration device, the groove will occupy the storage space of the inner liner, resulting in a loss of the volume of the refrigeration device.

[0047] Combined with Figures 1 to 9 As shown, the embodiments of the present disclosure provide a refrigeration device to avoid occupying the storage space of the inner liner 30 when the air duct cover plate is connected to the inner liner 30 and avoid reducing the volume ratio of the refrigeration device.

[0048] Refrigeration devices include refrigerators, freezers, etc. In the embodiments of the present disclosure, taking a refrigerator as an example, the refrigerator includes an inner liner 30 and an air duct cover plate.

[0049] Optionally, combined with Figure 1 and Figure 2 As shown, the refrigeration device includes: an inner liner 30, a first air duct cover plate 10, a second air duct cover plate 20, and a blower 40. The first air duct cover plate 10 covers the inner liner 30 and jointly encloses a first air duct 12 with the inner liner 30; the second air duct cover plate 20 covers the inner liner 30 and jointly encloses a second air duct 25 with the inner liner 30, and the second air duct 25 is communicated with the first air duct 12; the blower 40 is arranged in the second air duct 25; wherein, the first air duct cover plate 10 is connected to the inner liner 30 by screws 50.

[0050] Optionally, combined with Figure 3As shown, the air duct cover plate includes a front air duct cover plate and a rear air duct cover plate 28. The front air duct cover plate and the rear air duct cover plate 28 are connected to each other by snap connection to define a first air duct 12 and a second air duct 25. Among them, the front air duct cover plate includes a first air duct cover plate 10 and a second air duct cover plate 20. The first air duct cover plate 10 and the rear air duct cover plate 28 define the first air duct 12, the second air duct cover plate 20 and the rear air duct cover plate 28 define the second air duct 25, and the first air duct 12 is communicated with the second air duct 25. The fan 40 is arranged in the second air duct 25.

[0051] Because the fan 40 is arranged in the second air duct 25, at least part of the structure of the second air duct cover plate 20 needs to protrude towards the middle of the inner container 30, so that the second air duct cover plate 20 and the rear air duct cover plate 28 can form a fan 40 accommodation cavity with sufficient volume. Due to the arrangement of the fan 40, the storage space of the inner container 30 will inevitably be occupied. At the first air duct cover plate 10, since it is not affected by the fan 40, the volume of the storage compartment corresponding to the first air duct cover plate 10 is not affected. In the embodiment of the present disclosure, when the first air duct cover plate 10 is fixedly connected to the inner container 30, the volume of the storage compartment corresponding to the first air duct cover plate 10 is not reduced. Thus, when the first air duct cover plate 10 is connected to the inner container 30, the volume ratio of the refrigeration device is not reduced.

[0052] The first air duct cover plate 10 and the inner container 30 are connected by screws 50, which simplifies the connection method, does not require changing the structure of the inner container 30, and does not require at least part of the inner container 30 to protrude in the direction away from the first air duct cover plate 10 to form a groove, avoiding occupying the storage space of the inner container 30, and thus avoiding reducing the volume ratio of the refrigeration device.

[0053] In the above embodiment, the first air duct cover plate 10 and the second air duct cover plate 20 are arranged corresponding to the rear wall of the inner container 30, the fan 40 is arranged at the rear back of the inner container 30, and the first air duct cover plate 10 and the inner container 30 are connected by screws 50, avoiding reducing the size of the storage space in the depth direction of the inner container 30. When the first air duct cover plate 10 and the second air duct cover plate 20 are arranged corresponding to the side wall of the inner container 30 and the fan 40 is arranged at the side of the inner container 30, the first air duct cover plate 10 and the inner container 30 are connected by screws 50, avoiding reducing the size of the storage space in the width direction of the inner container 30.

[0054] Optionally, as shown in combination with Figure 6 The first air duct cover plate 10 is provided with a plurality of first screw holes 14, the inner container 30 is provided with a plurality of second screw holes 34, and the screw 50 passes through a corresponding first screw hole 14 and a second screw hole 34 to connect the first air duct cover plate 10 and the inner container 30 by screws 50; among them, the plurality of first screw holes 14 are respectively arranged on both sides in the width direction of the first air duct cover plate 10.

[0055] The number of screws 50 can be multiple. Exemplarily, the number of screws 50 is two, and the two screws 50 are respectively arranged on both sides of the first air duct cover 10 in the width direction, so as to make the fixation of the first air duct cover 10 and the inner container 30 more stable.

[0056] Optionally, a plurality of first screw holes 14 are respectively arranged on both sides of the first air duct cover 10 in the width direction, and along the width direction of the first air duct cover 10, the screws 50 are symmetrically arranged. This can make the forces on both sides of the first air duct cover 10 in the width direction more uniform and prevent the screws 50 from fatigue fracture.

[0057] It can be understood that the setting position of the screw 50 can be set according to the force condition of the first air duct cover 10. When the blower 40 is arranged at a position biased to the left along the width direction of the first air duct cover 10, the number of screws 50 can be increased on the left side of the first air duct cover 10.

[0058] Optionally, as shown in Figure 6 at least a part of the first air duct cover 10 protrudes towards the rear wall surface of the inner container 30 to form a screw groove 11, the first screw hole is arranged in the screw groove 11, the rear air duct cover 28 is provided with a limiting ring groove 24, the limiting ring groove 24 is sleeved on the screw groove 11, and the limiting ring groove 24 abuts against the screw groove 11.

[0059] In this way, when the screw 50 passes through the first screw hole 14 and the second screw hole 34, due to the blockage of the screw groove 11, the screw 50 can be prevented from contacting the air flow in the air duct, thereby avoiding the screw 50 from rusting.

[0060] Optionally, as shown in Figure 2 and Figure 3 the first air duct cover 10 is provided with a first limiting portion 13, the inner container 30 is provided with a first limiting and cooperating portion 31, and the first limiting portion 13 cooperates with the first limiting and cooperating portion 31 to limit the movement of the first air duct cover 10 relative to the inner container 30 along its own width direction.

[0061] The accuracy of the installation position of the air duct cover is crucial for the airtightness of the air duct. Therefore, when the first air duct cover 10 is fixedly connected to the inner container 30 by using the screw 50, positioning needs to be carried out first to ensure the accuracy of the installation position.

[0062] By providing the first limiting portion 13 on the first air duct cover 10 and the first limiting and cooperating portion 31 on the inner container 30, and the first limiting portion 13 cooperating with the first limiting and cooperating portion 31 to limit the movement of the first air duct cover 10 relative to the inner container 30 along its own width direction, so as to realize the limitation of the first air duct cover 10 along its own width direction. That is, the left and right limitation of the first air duct cover 10. Refer to the left and right directions indicated by the arrows in Figure 1 as shown.

[0063] Optionally, the first limiting portion 13 or the first limiting and mating portion 31 may include a limiting post, that is, a relatively small limiting post is provided on the inner wall surface of the inner tank 30 facing the first air duct cover plate 10. Without affecting the volume of the inner tank 30, the limiting post is used to limit the first air duct cover plate 10 in its own width direction.

[0064] Optionally, one of the first limiting portion 13 and the first limiting and mating portion 31 is a limiting protrusion 131, and the other is a limiting groove 311, and the limiting protrusion 131 is inserted into the limiting groove 311.

[0065] Optionally, at least part of the structure of the inner tank 30 protrudes in a direction away from the first air duct cover plate 10 to form a limiting groove 311, and at least part of the structure of the rear air duct cover plate 28 protrudes in a direction away from the first air duct cover plate 10 to form a limiting protrusion 131. The limiting protrusion 131 is inserted into the limiting groove 311 to limit the first air duct cover plate 10 in its own width direction.

[0066] When at least part of the structure of the inner tank 30 protrudes in a direction away from the first air duct cover plate 10 to form a limiting groove 311, the protruding dimension should be as small as possible and only be able to play a preliminary limiting role. Because if the protruding dimension is large, it will affect the filling of the foaming material or occupy the storage space in the depth direction of the inner tank 30.

[0067] Optionally, the first limiting portion 13 is located in the middle of the first air duct cover plate 10 in the width direction.

[0068] In this way, the first air duct cover plate 10 is symmetric about the first limiting portion 13 left and right, preventing the first air duct cover plate 10 from being skewed during installation.

[0069] Optionally, as shown in combination with Figure 7 and Figure 8 , the second air duct cover plate 20 is provided with a second limiting portion 26, and the inner tank 30 is provided with a second limiting and mating portion 32. The second limiting portion 26 and the second limiting and mating portion 32 cooperate to connect the second air duct cover plate 20 to the inner tank 30.

[0070] Optionally, one of the second limiting portion 26 and the second limiting and mating portion 32 is a buckle 261, and the other is a card slot 321 adapted to the buckle 261. The buckle 261 is inserted into the card slot 321 to snap the second air duct cover plate 20 to the inner tank 30.

[0071] Optionally, at least part of the structure of the second air duct cover plate 20 protrudes towards the inner tank 30 to form a buckle 261, and at least part of the structure of the inner tank 30 protrudes in a direction away from the first air duct cover plate 10 to form a card slot 321. The buckle 261 is inserted into the card slot 321 to pre-assemble the second air duct cover plate 20.

[0072] The second limiting part 26 and the second limiting and cooperating part 32 limit the second air duct cover plate 20 in such a way that the buckle 261 is inserted into the clamping groove 321. When the second air duct cover plate 20 is assembled and connected to the inner container 30, by inserting the buckle 261 into the clamping groove 321, pre-assembly of the second air duct cover plate 20 is achieved, and then left and right limiting is realized by the cooperation of the first limiting part 13 and the first limiting and cooperating part 31. Since the second air duct cover plate 20 is connected to the first air duct cover plate 10, the second limiting part 26 and the second limiting and cooperating part 32 can achieve pre-assembly of the whole air duct cover plate.

[0073] Optionally, the second air duct cover plate 20 includes a cover plate main body 21, a side wall 22 and an extension wall 23. The cover plate main body 21 is disposed opposite to the inner container 30; the side wall 22 is disposed between the cover plate main body 21 and the inner container 30, and the cover plate main body 21, the side wall 22 and the inner container 30 jointly define the second air duct 25; the extension wall 23 is connected to the side wall 22 and is located outside the second air duct 25, and the second limiting part 26 is disposed on the extension wall 23.

[0074] The second limiting part 26 is a buckle 261, and the second limiting and cooperating part 32 is a clamping groove 321. Along the width direction of the second air duct cover plate 20, the extension walls 23 are arranged on the opposite sides of the second air duct cover plate 20, and the buckles 261 are disposed on the extension walls 23 and are located outside the second air duct 25 to ensure that the airtightness of the second air duct 25 is not affected when the buckles 261 are matched with the clamping grooves 321.

[0075] Optionally, as shown in Figure 8 and Figure 9 , the second air duct cover plate 20 is provided with a third limiting part 27, and the inner container 30 is provided with a third limiting and cooperating part 33. The third limiting part 27 and the third limiting and cooperating part 33 cooperate to connect the second air duct cover plate 20 to the inner container 30.

[0076] Optionally, one of the third limiting part 27 and the third limiting and cooperating part 33 is a limiting bump 271, and the other is a limiting groove 331. The limiting bump 271 is inserted into the limiting groove 331 to limit the second air duct cover plate 20 in its own height direction. That is, up and down limiting of the second air duct cover plate 20 is achieved. Among them, the up and down direction is the direction indicated by the arrow in Figure 1 .

[0077] When assembling and connecting the first air duct cover plate 10 and the second air duct cover plate 20 to the inner container 30, first, the second limiting portion 26 is engaged with the second limiting mating portion 32, so that the buckle 261 is inserted into the card slot 321 to pre-assemble the first air duct cover plate 10 and the second air duct cover plate 20. Then, the first limiting portion 13 is engaged with the first limiting mating portion 31, so that the limiting protrusion 131 is inserted into the limiting groove 311 to limit the first air duct cover plate 10 and the second air duct cover plate 20 in the width direction of the first air duct cover plate 10 itself, that is, to limit the left and right directions. Finally, the third limiting portion 27 is engaged with the third limiting mating portion 33, so that the limiting bump 271 is inserted into the limiting slot 331 to limit the first air duct cover plate 10 and the second air duct cover plate 20 in the height direction of the second air duct cover plate 20 itself, that is, to limit the up and down directions, thereby accurately fixing the first air duct cover plate 10 and the second air duct cover plate 20 to the inner container 30. At the position of the inner container 30 corresponding to the first air duct cover plate 10, by providing the second screw hole 34 to replace the groove in the prior art, the storage space in the depth direction of the inner container 30 is not occupied, thereby ensuring the volume ratio of the refrigeration equipment.

[0078] Optionally, in combination with Figure 1 and Figure 2 as shown, the depth of the second air duct 25 is greater than the depth of the first air duct 12. Wherein, the depth direction here is Figure 1 the up and down direction in

[0079] In the direction from top to bottom, the first air duct cover plate 10 and the second air duct cover plate 20 are arranged in sequence, the second air duct cover plate 20 is connected to the first air duct cover plate 10, and the second air duct cover plate 20 is arranged below the first air duct cover plate 10. The fan 40 is arranged at the second air duct cover plate 20. So that when the first air duct cover plate 10 is connected to the inner container 30, the volume ratio of the refrigeration equipment is not reduced.

[0080] Optionally, the second air duct cover plate 20 protrudes towards the middle of the inner container 30.

[0081] In this way, a fan accommodation cavity is defined between the second air duct cover plate 20 and the inner container 30, and the fan 40 is arranged between the second air duct cover plate 20 and the inner container 30.

[0082] The refrigeration device provided by the embodiments of the present disclosure can achieve the following technical effects: The refrigeration device includes an inner container 30, a first air duct cover plate 10, a second air duct cover plate 20, and a fan 40. The first air duct cover plate 10 is disposed on the inner container 30 and together with the inner container 30 defines a first air duct 12. The second air duct cover plate 20 is disposed on the inner container 30 and together with the inner container 30 defines a second air duct 25. The first air duct cover plate 10 is connected to the second air duct cover plate 20, and the second air duct 25 is communicated with the first air duct 12. The fan 40 is disposed in the second air duct 25. Wherein, the first air duct cover plate 10 is connected to the inner container 30 by screws 50, so that when the first air duct cover plate 10 is connected to the inner container 30, the connection structure does not occupy the storage space of the inner container 30, thereby avoiding reducing the volume ratio of the refrigeration device.
