[0039] The present application will be described below in conjunction with the drawings and specific embodiments:

[0040] The self-locking structure in the refrigeration equipment provided by the present application is at least partially located in the accommodating groove of the door body and is not exposed, so that the refrigeration equipment is more beautiful.

[0041] Please refer to Figure 1 and Figure 2 The refrigeration equipment 100 provided by the present application includes a box body 110, a door body 120, a first hinge member 130 and a second hinge member 140.

[0042] The box 110 is a basic component of the refrigeration device 100, please refer to Figure 3 The box 110 is provided with a storage cavity 111 and a taking and placing opening 112 communicated with the storage cavity 111. Food, medicine and cosmetics that need to be stored at low temperature can be placed in the storage cavity 111 through the taking and placing opening 112, so that the shelf life of the goods is extended.

[0043] The door body 120 can open or close the taking and placing opening 112. When the door body 120 is opened, the goods can be taken out through the taking and placing opening 112. When the door body 120 is closed, the storage cavity 111 can be kept warm, the heat exchange between the refrigeration device 100 and the outside is reduced, and the storage effect of the goods in the storage cavity 111 is improved.

[0044] The first hinge part 130 and the second hinge part 140 are provided to realize the hinging of the door body 120 and the box 110, and to realize the opening or closing of the taking and placing opening 112. The first hinge part 130 is installed on the box 110, please refer to Figure 3 The second hinge part 140 is installed on the door body 120, and the first hinge part 130 is hinged with the second hinge part 140. Therefore, the door body 120 can be rotatably arranged relative to the box 110, so as to realize the closing and opening of the box 110. The first hinge part 130 comprises a first self-locking part 133, and the second hinge part 140 comprises a second self-locking part 144. When the door body 120 is closed, the first self-locking part 133 and the second self-locking part 144 are locked and matched, so as to ensure that the door body 120 stably covers the taking and placing opening 112, and to avoid the problem of cold loss caused by accidental opening of the door body 120.

[0045] For the convenience of introduction, it is judged from the perspective of standing in front of the refrigeration device 100, please refer to Figure 1 The direction from front to back of the box 110 is defined as the thickness direction, which can also be called the depth direction. The direction from left to right of the box 110 is the width direction. The direction from top to bottom of the box 110 is the height direction. After understanding the thickness direction, the width direction and the height direction of the box 110, the door body 120, the first hinge part 130 and the second hinge part 140 of the refrigeration device are further introduced.

[0046] Please refer to Figure 4 and Figure 5 Since the door body 120 is provided with the accommodating groove 1231, and the second self-locking part 144 of the second hinge part 140 is located in the accommodating groove 1231, the second self-locking part 144 cannot be seen from the outside of the refrigeration device 100 when the door body 120 closes the box 110. The appearance is more simple and integrated, and a better visual effect is brought.

[0047] In some embodiments, the door body 120 can include a door seal 121, a main body 122, and a mounting portion 123. The door seal 121 is mounted to the main body 122 near one side of the cabinet 110. When the door body 120 closes the cabinet 110, the door seal 121 abuts and seals against the cabinet 110, thereby improving the heat preservation performance of the refrigeration device 100.

[0048] The mounting portion 123 is connected to the main body 122. The mounting portion 123 can be disposed above the main body 122 (if the door body 120 is a door body of a freezing chamber, the mounting portion 123 is disposed above the main body 122), or below the main body 122 (if the door body 120 is a door body of a refrigerating chamber, the mounting portion 123 is disposed below the main body 122). The position of the mounting portion 123 relative to the main body 122 is not limited.

[0049] Since the door seal 121 is disposed on the main body 122 and is used to seal the gap between the main body 122 and the cabinet 110, it indicates that the main body 122 is the part of the entire door body 120 that mainly closes or opens the access opening 112, and it also indicates that the mounting portion 123 is located outside the storage cavity 111.

[0050] The accommodation groove 1231 is disposed on the mounting portion 123. In the thickness direction of the cabinet 110, the thickness of the main body 122 is less than the thickness of the mounting portion 123. In the refrigeration device 100, in order to achieve an ultra-thin door body as much as possible, the door body 120 is basically thin. The thickness of the mounting portion 123 is greater than the thickness of the main body 122, which can accommodate the second self-locking portion 144 on the mounting portion 123 without increasing the thickness of the main body 122.

[0051] At the same time, since the accommodation groove 1231 is disposed on the mounting portion 123, the strength of the mounting portion 123 is reduced to a certain extent. Therefore, the thickness of the mounting portion 123 is greater than the thickness of the main body 122, which can improve the strength of the mounting portion 123, thereby ensuring the strength of the door body 120.

[0052] In other embodiments, the thickness of the mounting portion 123 can be the same as or less than the thickness of the main body 122. The accommodation groove 1231 can still be disposed on the mounting portion 123 to accommodate the second self-locking portion 144.

[0053] In some embodiments, the thickness of the main body 122 can be 25-40 mm, for example 28 mm, 30 mm, 35 mm, 38 mm or 39 mm, etc. The thickness of the main body 122 is relatively small, so that the size of the refrigeration device 100 in the thickness direction can be reduced, which can be suitable for small space arrangement and large space arrangement, and has high versatility. In other embodiments, the thickness of the main body 122 can be greater than 40 mm, for example 42 mm or 45 mm, etc., and can be less than 25 mm, for example 24 mm or 23 mm, etc., which is not limited in the present application.

[0054] In some embodiments, the thickness of the refrigeration device 100 can be 450-600 mm, for example 460 mm, 480 mm, 500 mm, 510 mm, 530 mm, 550 mm or 570 mm, etc. The total thickness of the refrigeration device 100 is small, which can be suitable for small space arrangement and large space arrangement, and has high versatility. In other embodiments, the thickness of the refrigeration device 100 can be greater than 600 mm, for example 610 mm or 620 mm, etc., which can increase the volume of the storage cavity 111 and increase the storage capacity. Of course, the thickness of the refrigeration device 100 can also be less than 450 mm, for example 440 mm or 430 mm, etc., which is not limited in the present application.

[0055] In some embodiments, referring to Figure 6 , the surface of the main body 122 away from the cabinet 110 is flush with the surface of the mounting portion 123 away from the cabinet 110, and the surface of the mounting portion 123 close to the cabinet 110 protrudes from the surface of the main body 122 close to the cabinet 110. For ease of introduction, the part composed of the main body 122 and the mounting portion 123 is referred to as the door piece 125, the surface of the door piece 125 away from the cabinet 110 is referred to as the outer surface, and the surface of the door piece 125 close to the cabinet 110 is referred to as the inner surface. Among them, the surface of the main body 122 away from the cabinet 110 is flush with the surface of the mounting portion 123 away from the cabinet 110, that is, the outer surface of the door piece 125 is a plane, which improves the appearance effect of the refrigeration device.

[0056] The installation portion 123 protrudes from the surface of the main body 122 close to the cabinet 110, that is, the inner surface of the door piece 125 is not planar. The door seal 121 is mainly used to seal the main body 122 and the cabinet 110. The door seal 121 can be made of a material with a certain elasticity, and is generally annular, such as rectangular or square, etc. In order to improve the sealing effect of the door seal 121 and the cabinet 110, the door seal 121 generally has a certain thickness, so that the main body 122 and the cabinet 110 have a certain distance. The installation portion 123 is arranged above or below the main body 122, and the door seal 121 is arranged on the main body 122. Therefore, the installation portion 123 is arranged above or below the door seal 121. The installation portion 123 protrudes from the surface of the main body 122 close to the cabinet 110. The installation portion 123 is arranged by using the distance between the main body 122 and the cabinet 110 (using the space above or below the door seal 121). The installation portion 123 can be arranged with a receiving groove 1231 capable of accommodating the second self-locking portion 144 without increasing the thickness of the door body 120. Therefore, the structure of the entire door body 120 is more compact, and the space occupied is small.

[0057] In some embodiments, referring to Figure 4 and Figure 5 , the installation portion 123 is further provided with a handle groove 1233, which facilitates opening of the door body 120. The handle groove 1233 is arranged side by side with the receiving groove 1231 along the width direction of the cabinet 110.

[0058] The handle groove 1233 and the receiving groove 1231 are located on the same side of the door body 120, which not only ensures the strength of the door body 120, but also facilitates processing. In another embodiment, the handle groove 1233 and the receiving groove 1231 are in communication with each other, that is, the handle groove 1233 is directly formed on the door body 120, and the second self-locking portion 144 is located in the handle groove 1233. Without additionally forming a groove structure, the arrangement of the second self-locking portion 144 can be realized. In still other embodiments, for a refrigeration equipment provided with two door bodies 120, the two door bodies 120 are arranged in an up-down manner. The handle groove 1233 can also be arranged on the side of the main body 122, that is, the handle groove 1233 and the receiving groove 1231 are located on different sides of the door body 120. The reasonable arrangement of the handle groove 1233 and the receiving groove 1231 can also be realized.

[0059] In some embodiments, the door body 120 has an opening 1232 close to one side of the cabinet 110. The opening 1232 is in communication with the receiving groove 1231, that is, the receiving groove 1231 has a groove opening 1234 and the opening 1232.

[0060] In some embodiments, the opening 1232 can be located on the side of the door body 120 close to the cabinet 110, and the slot 1234 can be located on the side of the door body 120. When the door body 120 closes the cabinet 110, the first self-locking part 133 can be arranged in the accommodating groove 1231 through the opening 1232, so as to avoid interference between the first self-locking part 133 and the door body 120 during rotation of the door body 120 relative to the cabinet 110.

[0061] In other embodiments, the slot 1234 can also be located on the side of the door body 120 close to the cabinet 110, and the opening 1232 can be located on the side of the door body 120. When the door body 120 closes the cabinet 110, the first self-locking part 133 can be arranged in the accommodating groove 1231 through the slot 1234. In still other embodiments, the opening 1232 can also be provided with two openings, one of which is located on the side of the main body 122 close to the cabinet 110, and the other opening 1232 and the slot 1234 are respectively located on the two adjacent sides of the main body 122, so as to not affect the appearance of the refrigeration equipment 100, and also facilitate maintenance of the first hinge part 130 and the second hinge part 140 through the opening 1232 located on the side of the main body 122.

[0062] When the opening 1232 is provided on the mounting part 123, the part of the mounting part 123 protruding relative to the main body 122 can extend around the edge of the opening 1232, and the extension length can be arranged only on part of the edge of the opening 1232, or can be arranged on all edges of the opening 1232, which is not limited in the present application.

[0063] In some embodiments, the shape of the accommodating groove 1231 can be a cuboid shape, or a semispherical shape, and the shape of the accommodating groove 1231 is not limited in the present application.

[0064] In some embodiments, when the door body 120 closes the cabinet 110, there is a gap between the mounting part 123 and the cabinet 110. During the entire process of switching the refrigeration equipment 100 from the open state of the taking and placing opening 112 to the state of covering the taking and placing opening 112 by the door body 120, the mounting part 123 is always arranged in a spaced manner with the cabinet 110, the door body 120 can be freely rotated without interference with the cabinet 110, the first self-locking part 133 and the second self-locking part 144 can be smoothly locked and matched, and the locking effect is guaranteed. In some embodiments, the size of the door seal 121 in the thickness direction of the cabinet 110 is greater than the size of the mounting part 123, so that when the door body 120 closes the cabinet 110, there is a gap between the mounting part 123 and the cabinet 110.

[0065] The first hinge part 130 is installed on the cabinet 110 and is a structure with fixed position, please refer toFigure 7 The first hinge piece 130 comprises a first hinge seat 131, a hinge shaft 132 and the aforementioned first self-locking part 133. The first hinge seat 131 is connected to the cabinet 110, for example, by a threaded connection, to achieve the installation and fixation of the first hinge piece 130. The hinge shaft 132 is installed in the first hinge seat 131 and is used to achieve the hinging with the second hinge seat 142. The first self-locking part 133 comprises a first connecting segment 1331 and a self-locking segment 1332. The first connecting segment 1331 is connected to the first hinge seat 131 and the self-locking segment 1332, respectively, to achieve the arrangement of the self-locking segment 1332 and facilitate the locking cooperation with the second self-locking part 144.

[0066] In some embodiments, please continue to refer to Figure 7 Along the height direction of the cabinet 110, the self-locking segment 1332 is arranged in a spaced manner with the first hinge seat 131, so that the self-locking segment 1332 extends into the accommodating groove 1231 to lock with the second self-locking part 144 when the door body 120 closes the cabinet 110, and the first hinge seat 131 is located outside the door body 120, facilitating the maintenance of the first hinge seat 131. In addition, the spaced arrangement of the self-locking segment 1332 and the first hinge seat 131 along the height direction of the cabinet 110 can also prevent the door body 120 from interfering with the first hinge seat 131 when the door body 120 rotates relative to the cabinet 110, and smoothly achieve the opening or closing of the cabinet 110.

[0067] In other embodiments, the first hinge seat 131 and the first self-locking part 133 can also have the same height. In this scheme, the opening 1232 of the door body 120 needs to be enlarged, so that the first hinge seat 131 and the first self-locking part 133 can be arranged in the accommodating groove 1231 through the opening 1232 when the door body 120 closes the cabinet 110.

[0068] In some embodiments, please continue to refer to Figure 7 Along the width direction of the cabinet 110, the self-locking segment 1332 is arranged in a spaced manner with the first hinge seat 131, so that the self-locking segment 1332 is spaced from the first hinge seat 131, increasing the size of the first hinge piece 130 in the width direction of the cabinet 110, facilitating the arrangement of the first hinge seat 131 and the hinge shaft 132 on the first hinge seat 131. At the same time, the spaced arrangement of the self-locking segment 1332 and the first hinge seat 131 can also adaptively shorten the size of the second self-locking part 144 in the width direction of the cabinet 110, to a certain extent, so that the elasticity of the second self-locking part 144 is not too large, and the locking effect of the second self-locking part 144 and the rigid self-locking segment 1332 is improved. In other embodiments, along the width direction of the cabinet 110, the self-locking segment 1332 is arranged close to the first hinge seat 131, and the self-locking can still be achieved.

[0069] In some embodiments, please continue to refer to Figure 7, the first connecting section 1331 is arranged obliquely relative to the first hinge seat 131, so that the self-locking section 1332 is arranged spaced apart from the first hinge seat 131 in the height direction of the cabinet 110 and is arranged staggered in the width direction of the cabinet 110. The spaced apart arrangement of the self-locking section 1332 from the first hinge seat 131 in the height direction of the cabinet 110 not only enables the self-locking section 1332 to lock with the second self-locking portion 144 when the door body 120 closes the cabinet 110, but also enables the door body 120 to rotate relative to the cabinet 110 without interfering with the first hinge seat 131, so that the cabinet 110 can be opened or closed smoothly. The staggered arrangement of the self-locking section 1332 from the first hinge seat 131 in the width direction of the cabinet 110 not only enables the first hinge seat 131 to be arranged with the hinge shaft 132, but also improves the locking effect of the second self-locking portion 144 and the rigid self-locking section 1332.

[0070] In other embodiments, the first connecting section 1331 is arranged in the height direction, so that the self-locking section 1332 is arranged spaced apart from the first hinge seat 131 in the height direction of the cabinet 110 and is arranged at least partially staggered in the width direction of the cabinet 110.

[0071] The second hinge piece 140 is installed on the door body 120 and changes position with the rotation of the door body 120, please refer to Figure 8 The second hinge piece 140 includes a second hinge seat 142 and a positioning portion 141, the second hinge seat 142 is installed on the door body 120, for example, by a threaded member, the positioning portion 141 and the second self-locking portion 144 are both installed on the second hinge seat 142, please refer to Figure 5 The hinge shaft 132 of the first hinge piece 130 has a limiting surface 1321, the hinge shaft 132 cooperates with the positioning portion 141, and the positioning portion 141 abuts against the limiting surface 1321 to realize the positioning of the second hinge piece 140 in the axial direction of the hinge shaft 132.
