[0037] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a door adjustment mechanism, including: a first adjustment module 1. The first adjustment module 1 includes: a first mounting base 11, a first adjustment component 12, a second adjustment component 13, and a third adjustment component 14. The first mounting base 11 is configured to be connected to a cabinet door 4. The first adjustment component 12 and the second adjustment component 13 are respectively disposed on the cabinet door 3, and the third adjustment component 14 is disposed on the first adjustment component 12. The first adjustment component 12 is used to adjust the position of the third adjustment component 14 relative to the cabinet door 3 along the height direction of the cabinet door 3. The second adjustment component 13 and the third adjustment component 14 are respectively connected to the first mounting base 11. The second adjustment component 13 is used to adjust the position of the first mounting base 11 relative to the cabinet door 3 along the width direction of the cabinet door 3. The second adjustment component 13 is used to adjust the position of the first mounting base 11 relative to the cabinet door 3 along the thickness direction of the cabinet door 3.

[0038] It should be noted that, in this invention, the height direction of the cabinet door 3 refers to the vertical direction when the cabinet door 3 is normally installed in a household appliance (e.g., Figure 1 The thickness direction of the door 3 (in the Z direction) refers to the direction perpendicular to the front of the door 3 (i.e., the side facing the user) (e.g., the direction of thickness of the door 3). Figure 1 (in the Y direction), the width direction of the door 3 is perpendicular to both the height and thickness directions (e.g., Figure 1 (in the X direction).

[0039] Understandably, in this embodiment, the first adjustment module 1 is positioned between the cabinet door 3 and the cabinet door 4 of the household appliance, and is used to adjust the relative position of the cabinet door 4 and the cabinet door 3 based on the cabinet door 3. Specifically, both the first adjustment component 12 and the second adjustment component 13 are directly connected to the cabinet door 3. The first adjustment component 12 is connected to the first mounting base 11 through the third adjustment component 14, and the second adjustment component 13 is directly connected to the first mounting base 11. The first mounting base 11 is used to directly connect to the cabinet door 4. The third adjustment component 14 can directly adjust the position of the first mounting base 11 relative to the cabinet door 3 along the thickness direction of the cabinet door 3, and drives the cabinet door 4 to move through the first mounting base 11, thereby adjusting the position of the cabinet door 4 in the thickness direction of the cabinet door 3. Simultaneously, the second adjustment component 13 can directly adjust the position of the first mounting base 11 relative to the cabinet door 3 along the width direction of the cabinet door 3, and drives the cabinet door 4 to move through the first mounting base 11, thereby adjusting the position of the cabinet door 4 in the width direction of the cabinet door 3. In addition, the third adjustment component 14 is disposed on the first adjustment component 12. The first adjustment component 12 can adjust the position of the third adjustment component 14 relative to the door 3 along the height direction of the door 3. The cabinet door 4 is moved by the third adjustment component 14 and the first mounting base 11 to adjust the position of the cabinet door 4 in the height direction of the door 3.

[0040] According to the door adjustment mechanism of the present invention, a first adjustment module 1 is provided between the cabinet door 3 and the box door 4. The first adjustment component 12 and the second adjustment component 13 of the first adjustment module 1 are respectively provided on the cabinet door 3. The first mounting base 11 is connected to the cabinet door 4. The first adjustment component 12 can drive the cabinet door 4 to move relative to the cabinet door 3 along the height direction of the cabinet door 3 through the third adjustment component 14 and the first mounting base 11 to adjust the position of the cabinet door 4 in the height direction of the cabinet door 3. The second adjustment component 13 can drive the cabinet door 4 to move relative to the cabinet door 3 along the width direction of the cabinet door 3 through the first mounting base 11 to adjust the position of the cabinet door 4 in the width direction of the cabinet door 3. The third adjustment component 14 can drive the cabinet door 4 to move relative to the cabinet door 3 along the thickness direction of the cabinet door 3 through the first mounting base 11 to adjust the position of the cabinet door 4 in the thickness direction of the cabinet door 3. Thus, the relative position of the cabinet door 4 and the box door 3 can be adjusted in three directions. During the adjustment process, the entire first adjustment module 1 can still maintain the connection and support of the cabinet door 4, making the adjustment operation more convenient and effortless.

[0041] In some embodiments, such as Figure 2 , Figure 3 and Figure 4As shown, the first adjustment assembly 12 includes a first sliding member 121, a second sliding member 122, and a first drive assembly 123. The first sliding member 121 is slidably disposed on the door 3 along the width direction of the door 3, and a guide slope 1211 is formed on the first sliding member 121, which is inclined relative to the horizontal plane. The second sliding member 122 is slidably disposed on the door 3 along the height direction of the door 3, and a portion of the structure of the second sliding member 122 is disposed on the guide slope 1211. The third adjustment assembly 14 is disposed on the second sliding member 122. The first drive assembly 123 is drively connected to the first sliding member 121 to drive the first sliding member 121 to slide along the width direction of the door 3.

[0042] In this embodiment, the first drive assembly 123 and the first slider 121 are connected by a transmission. The first drive assembly 123 is used to drive the first slider 121 to move along the width direction of the cabinet door 3. Part of the structure of the second slider 122 is disposed on the guide slope 1211 of the first slider 121, and the second slider 122 is configured to slide only along the height direction of the cabinet door 3. When the first slider 121 slides along the width of the cabinet door 3, the second slider 122 will move relative to the first slider 121 along the guide slope 1211, thereby sliding in the height direction of the cabinet door 3, and driving the third adjustment assembly 14, the first mounting base 11 and the cabinet door 4 as a whole to move along the height direction of the cabinet door 3, thereby adjusting the relative position of the cabinet door 4 and the cabinet door 3 along the height direction of the cabinet door 3.

[0043] Specifically, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the first adjustment module 1 also includes a first base 15, which is disposed on the door 3. A first mounting cavity is constructed within the first base 15, and the first adjustment component 12, the second adjustment component 13, and the third adjustment component 14 are all installed within the first mounting cavity. It can be understood that, in order to constrain and limit the movement direction of the first sliding member 121 and the second sliding member 122, the first mounting cavity is respectively provided with limiting structures or guiding structures adapted to the first sliding member 121 and the second sliding member 122.

[0044] For example, for the first sliding member 121, the first mounting cavity has guide protrusions extending along the width direction of the door 3 on the opposite sides of the cavity wall along the thickness direction of the door 3. The first sliding member 121 has a sliding groove at the position corresponding to the guide protrusion. The guide protrusion is slidably inserted into the sliding groove, so that the first sliding member 121 can only slide along the width direction of the door 3.

[0045] For the second sliding member 122, the four side walls of the first mounting cavity abut against the side walls of the second sliding member 122 respectively. There is a certain gap between the top and bottom walls of the first mounting cavity and the second sliding member 122, so that the second sliding member 122 can slide up and down relative to the first mounting cavity.

[0046] Specifically, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the second sliding member 122 is provided with two guide structures 1221. The guide structure 1221 has a contact surface parallel to the guide inclined surface 1211 and an end surface perpendicular to the horizontal plane. The contact surfaces of the two guide structures 1221 are arranged opposite to each other, and the end surfaces of the two guide structures 1221 are respectively oriented towards both sides along the width direction of the door 3. A guide channel is formed between the two contact surfaces.

[0047] The first sliding member 121 has a guide portion 1212 adapted to the guide channel and abutment portions 1213 disposed at both ends of the guide portion 1212. The guide portion 1212 is slidably disposed within the guide channel. The top and bottom of the guide portion 1212 are respectively formed with mutually parallel guide slopes 1211. The top guide slope 1211 contacts the contact surface of one of the guide structures 1221, and the bottom guide slope 1211 contacts the contact surface of the other guide structure 1221. One abutment portion 1213 is disposed opposite to the end face of one of the guide structures 1221, and the other abutment portion 1213 is disposed opposite to the end face of the other guide structure 1221. During the sliding process of the guide part 1212 along the guide channel, the two abutting parts 1213 can cooperate with the opposite end face. Specifically, when the guide part 1212 slides to the limit position along the guide channel to one side, one of the abutting parts 1213 abuts with the corresponding guide structure 1221, preventing the guide part 1212 from continuing to slide to that side. When the guide part 1212 slides to the limit position along the guide channel to the other side, the other abutting part 1213 abuts with the corresponding guide structure 1221, thereby limiting the relative sliding range of the second sliding member 122 and the first sliding member 121, and thus limiting the adjustment range of the second sliding member 122 along the height direction of the door 3.

[0048] Specifically, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the first drive assembly 123 includes a first limiting member and a first adjusting screw 1231. The first limiting member is configured to be disposed on the door 3. The first adjusting screw 1231 is disposed on the first limiting member, the screw of the first adjusting screw 1231 is threadedly connected to the first sliding member 121, and the first adjusting screw 1231 has a first screw head facing the side of the door 3, and the first limiting member abuts against both ends of the first screw head.

[0049] In this embodiment, the screw of the first adjusting screw 1231 and the first sliding member 121 are threaded together, and the first limiting member abuts against both ends of the first screw head of the first adjusting screw 1231, so as to limit the first adjusting screw 1231 in the width direction of the cabinet door 3. This allows the user to adjust the position of the first sliding member 121 in the width direction of the cabinet door 3 using the first adjusting screw 1231, thereby adjusting the position of the cabinet door 4 in the height direction of the cabinet door 3. Specifically, the first adjusting screw 1231 can only rotate and cannot move along the width direction of the cabinet door 3 under the limitation of the first limiting member, so that the user can tighten the first screw head with a screwdriver or other tools. The first sliding member 121 is configured to slide only along the width direction of the cabinet door 3 and will not rotate with the first adjusting screw 1231. Thus, the first sliding member 121 moves along the width direction of the cabinet door 3 under the drive of the threaded engagement, and then drives the second sliding member 122 to slide along the height direction of the cabinet door 3 through the guide slope 1211, thereby adjusting the position of the cabinet door 4 in the height direction of the cabinet door 3. Meanwhile, by placing the first screw head on the side of the cabinet door 3, the first screw head is not obstructed by the cabinet door 4, making it convenient for the user to screw it in. When the user screws in the first adjusting screw 1231, the first sliding member 121 and the second sliding member 122 have a small range of movement, which makes it convenient for the user to fine-tune the position of the cabinet door 4 relative to the cabinet door 3 in the height direction.

[0050] It is understandable that the first limiting member can be a clamping structure constructed on the first base 15 to clamp the two ends of the first screw head and limit the first adjusting screw 1231.

[0051] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the third adjustment assembly 14 includes a third slider 141, a fourth slider 142, and a second drive assembly 143. The third slider 141 is slidably disposed on the second slider 122 along the width direction of the door 3. A first guide groove 1411 is formed on the third slider 141, and the extension direction of the first guide groove 1411 is angled to the width direction of the door 3. The fourth slider 142 is slidably disposed on the second slider 122 along the thickness direction of the door 3. The fourth slider 142 has a first guide portion inserted into the first guide groove 1411 and is capable of sliding along the extension direction of the first guide groove 1411. The fourth slider 142 is connected to the first mounting base 11. The second drive assembly 143 is connected to the third slider 141 and is used to drive the third slider 141 to slide along the width direction of the door 3.

[0052] In this embodiment, the second drive assembly 143 and the third slider 141 are connected by a transmission. The second drive assembly 143 is used to drive the third slider 141 to move along the width direction of the door 3. The first guide portion of the fourth slider 142 is inserted into the first guide groove 1411 of the third slider 141, and the fourth slider 142 is configured to slide only along the thickness direction of the door 3. When the third slider 141 slides along the width of the door 3, the fourth slider 142 will move relative to the third slider 141 along the first guide groove 1411, thereby sliding relative to the door 3 along the thickness direction, and driving the first mounting base 11 and the cabinet door 4 as a whole to move along the thickness direction of the door 3, thereby adjusting the relative position of the cabinet door 4 and the door 3 along the thickness direction of the door 3.

[0053] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the second drive assembly 143 includes a second limiting member and a second adjusting screw 1431. The second limiting member is configured to be disposed on the door 3. The second adjusting screw 1431 is movably disposed on the second limiting member along the height direction of the door 3. The screw of the second adjusting screw 1431 is threadedly connected to a third sliding member 141, and the second adjusting screw 1431 has a second screw head facing the side of the door 3. The second limiting member abuts against both ends of the second screw head.

[0054] In this embodiment, by setting the second limiting member on the door 3, the second adjusting screw 1431 is movably set on the second limiting member along the height direction of the door 3, so that the second adjusting screw 1431 can move up and down on the second limiting member with the third sliding member 141 and the second sliding member 122 without affecting the movement of the second sliding member 122. By threading the screw of the second adjusting screw 1431 and the third sliding member 141, and by having the second limiting member abut against both ends of the second screw head of the second adjusting screw 1431, the second adjusting screw 1431 is limited in the width direction of the door 3, so that the user can adjust the position of the third sliding member 141 in the width direction of the door 3 by using the second adjusting screw 1431, thereby adjusting the position of the cabinet door 4 in the thickness direction of the door 3. Specifically, the second adjusting screw 1431, limited by the second limiting member, can only rotate and cannot move along the width direction of the cabinet door 3, allowing the user to tighten the second screw head using tools such as a screwdriver. The third sliding member 141 is configured to slide only along the width direction of the cabinet door 3 and will not rotate with the second adjusting screw 1431. This allows the third sliding member 141 to move along the width direction of the cabinet door 3 under the drive of the threaded engagement, and then drives the fourth sliding member 142 to slide along the thickness direction of the cabinet door 3 via the first guide groove 1411, thereby adjusting the position of the cabinet door 4 in the thickness direction of the cabinet door 3. Simultaneously, by placing the second screw head on the side of the cabinet door 3, it is not obstructed by the cabinet door 4, making it convenient for the user to tighten. When the user tightens the second adjusting screw 1431, the movement range of the third sliding member 141 and the fourth sliding member 142 is small, facilitating fine-tuning of the position of the cabinet door 4 relative to the thickness direction of the cabinet door 3.

[0055] It is understandable that the second limiting member can be a clamping structure constructed on the first base 15 to clamp the two ends of the second screw head and limit the second adjusting screw 1431.

[0056] Specifically, in some embodiments, the first base 15 has a first limiting plate 151 and a second limiting plate 152 disposed opposite to each other. The first limiting plate 151 has a first through hole corresponding to the first adjusting screw 1231, and the second limiting plate 152 has a second through hole corresponding to the first adjusting screw 1231. The first adjusting screw 1231 passes through the first through hole, so that the first screw head of the first adjusting screw 1231 is limited between the first limiting plate 151 and the second limiting plate 152, and the first screw head is exposed in the second through hole so that the user can screw it.

[0057] The first limiting plate 151 is also provided with a first oblong hole extending along the height direction of the door 3, corresponding to the second adjusting screw 1431. The second limiting plate 152 is also provided with a second oblong hole extending along the height direction of the door 3, corresponding to the second adjusting screw 1431. The second adjusting screw 1431 passes through the first oblong hole, so that the second screw head of the second adjusting screw 1431 is limited between the first limiting plate 151 and the second limiting plate 152, and the second screw head is exposed in the second oblong hole.

[0058] Specifically, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the fourth sliding member 142 is provided with a first hooking part 1421, and the first mounting base 11 is provided with a second hooking part 111 that is adapted to the first hooking part 1421. The first hooking part 1421 and the second hooking part 111 are hooked together.

[0059] In this embodiment, by providing a first hooking part 1421 and a second hooking part 111 that are adapted to each other on the fourth sliding member 142 and the first mounting base 11, the fourth sliding member 142 and the first mounting base 11 can be hooked together, so that the user can easily install the cabinet door 4 onto the box door 3 through the first adjustment module 1. Specifically, the user can first install the structure of the first adjustment module 1 except for the first mounting base 11 onto the box door 3, then install the first mounting base 11 onto the cabinet door 4, and finally hook the first mounting base 11 onto the fourth sliding member 142.

[0060] It is understandable that, in order to constrain and limit the movement direction of the third slider 141 and the fourth slider 142, the second slider 122 is respectively constructed with a limiting structure or a guiding structure that is adapted to the third slider 141 and the fourth slider 142.

[0061] For example, the second slider 122 is provided with a first mounting groove extending along the width direction of the door 3, and the third slider 141 is slidably disposed in the first mounting groove. A portion of the structure of the fourth slider 142 is located in the first mounting groove and can move along the thickness direction of the door 3.

[0062] Specifically, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the fourth sliding member 142 includes a first limiting part 1422 and a first hooking part 1421 connected together.

[0063] The first limiting part 1422 has a T-shaped structure, including a transverse part along the width direction of the door 3 and a longitudinal part along the height direction of the door 3. A detachable first limiting block 1222 is provided in the first mounting groove. The first limiting block 1222 is located at the junction of the transverse part and the longitudinal part on one side and abuts against the transverse part and the longitudinal part respectively. A first limiting structure 1223 is formed on the groove wall of the first mounting groove. The first limiting structure 1223 is located at the junction of the transverse part and the longitudinal part on the other side and abuts against the transverse part and the longitudinal part respectively. The first limiting block 1222 is used to cooperate with the first limiting structure 1223 to constrain the fourth sliding member 142, so that the fourth sliding member 142 can only move relative to the second sliding member 122 along the thickness direction of the door 3.

[0064] The first hook part 1421 is in the shape of a hook, and the second hook part 111 on the first mounting base 11 is provided with a hook groove. The hook groove extends along the width direction of the door 3 and has openings on both sides of the first mounting base 11 along the width direction of the door 3. The hook can slide into the hook groove from both sides and hook with the hook groove.

[0065] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the second adjustment assembly 13 includes a third limiting member 132 and a third adjusting screw 131. The third limiting member 132 is configured to be movably disposed on the door 3 along the thickness direction of the door 3. The third adjusting screw 131 is movably disposed on the third limiting member 132 along the height direction of the door 3. The screw of the third adjusting screw 131 is threadedly connected to the first mounting base 11, and the third adjusting screw 131 has a third screw head facing the side of the door 3. The third limiting member 132 abuts against both ends of the third screw head.

[0066] In this embodiment, by movably setting the third limiting member 132 along the thickness direction of the door 3 to the door 3, and movably setting the third adjusting screw 131 along the height direction of the door 3 to the second limiting member, when the first mounting base 11 moves along the height direction of the door 3 under the adjustment of the first adjusting component 12, the third adjusting screw 131 can move with the first mounting base 11. When the first mounting base 11 moves along the thickness direction of the door 3 under the adjustment of the third adjusting component 14, the third adjusting screw 131 and the third limiting member 132 can move together with the first mounting base 11 without affecting the movement of the first mounting base 11. By threading the screw of the third adjusting screw 131 to the first mounting base 11, and by having the third limiting member 132 abut against both ends of the third screw head of the third adjusting screw 131, the third adjusting screw 131 is limited in the width direction of the cabinet door 3. This allows the user to adjust the position of the first mounting base 11 in the width direction of the cabinet door 3 using the third adjusting screw 131, thereby adjusting the position of the cabinet door 4 in the width direction of the cabinet door 3. Specifically, the third adjusting screw 131 can only rotate and cannot move along the width direction of the cabinet door 3 under the limitation of the third limiting member 132, allowing the user to tighten the third screw head with a screwdriver or other tools. When the first adjusting assembly 12 and the second adjusting assembly 13 are not adjusted, the first mounting base 11 can only slide along the width direction of the cabinet door 3 and will not rotate with the second adjusting screw 1431. Thus, the first mounting base 11 moves along the width direction of the cabinet door 3 under the drive of the threaded engagement, thereby adjusting the position of the cabinet door 4 in the width direction of the cabinet door 3. Meanwhile, by placing the third screw head on the side of the cabinet door 3, the third screw head is not obstructed by the cabinet door 4, making it convenient for the user to screw it in. When the user screws in the third adjusting screw 131, the first mounting base 11 has a small range of motion, which makes it convenient for the user to fine-tune the position of the cabinet door 4 relative to the width direction of the cabinet door 3.

[0067] Specifically, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, a fixed seat 133 is installed on the first base 15. The third limiting member 132 is movably disposed on the fixed seat 133 along the thickness direction of the door 3. A limiting cavity is constructed inside the third limiting member 132. A third oblong hole and a fourth oblong hole extending along the height direction of the door 3 are respectively provided on both sides of the limiting cavity corresponding to the third adjusting screw 131. The third adjusting screw 131 passes through the third oblong hole, so that the third screw head is limited in the limiting cavity and exposed in the fourth oblong hole.

[0068] Optionally, the first, second, and third screw heads can be configured to face the same side of the cabinet door 3 to facilitate user adjustment of the positions of the cabinet door 4 and the cabinet door 3. Preferably, the first, second, and third screw heads can be configured to face the side of the cabinet door 3 away from the connection structure between the cabinet door 3 and the cabinet body.

[0069] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, there are two first adjustment modules 1, which are arranged at intervals along the width direction of the door 3.

[0070] In this embodiment, two first adjustment modules 1 are connected to the left and right parts of the cabinet door 4 along the width direction of the cabinet door 3. These two modules work together to adjust the relative position of the cabinet door 4 and the cabinet door 3, ensuring that the cabinet door 4 remains parallel to the cabinet door 3 when its position is adjusted, preventing it from tilting relative to the cabinet door 3. Specifically, when one of the first adjustment modules 1 adjusts the position of the cabinet door 4, since that module 1 is connected to the left or right half of the cabinet door 4, it may cause the left or right half of the cabinet door 4 to tilt. In this case, the user can adjust the other first adjustment module 1 to readjust the cabinet door 4. Simultaneously, the two first adjustment modules 1 provide support for the cabinet door 4, making it more stable and reliable.

[0071] Specifically, in some embodiments, the door 3 and the cabinet of the household appliance are connected by a hinge or other connecting structure. Two first adjustment modules 1 are arranged at intervals along the width direction of the door 3. One first adjustment module 1 is close to the connecting structure between the door 3 and the cabinet (for ease of explanation, it will be abbreviated as "proximal first adjustment module 1" below), and the other first adjustment module 1 is far away from the connecting structure (for ease of explanation, it will be abbreviated as "far-end first adjustment module 1" below).

[0072] Among them, such as Figure 2 , Figure 3 and Figure 4 As shown, the proximal first adjustment module 1 can share the first limiting plate 151 and the second limiting plate 152 with the distal first adjustment module 1. Specifically, the distal first adjustment module 1 has through holes corresponding to the first adjusting screw 1231 and the second adjusting screw 1431 of the proximal first adjustment module 1, so that the first adjusting screw 1231 and the second adjusting screw 1431 of the proximal first adjustment module 1 can pass through the first sliding member 121 and the second sliding member 122 of the distal first adjustment module 1 in sequence, and extend into the first base 15 of the distal first adjustment module 1, so that the first screw head and the second screw head of the two first adjustment modules 1 are both located between the first limiting plate 151 and the second limiting plate 152 of the distal first adjustment module 1, and exposed on the second limiting plate 152, so that the user can adjust the two first adjustment modules 1.

[0073] Furthermore, such as Figure 2 , Figure 3and Figure 4 As shown, the first adjustment module 1 at the proximal end may not have a second adjustment component 13.

[0074] In some embodiments, such as Figure 1 As shown, the door adjustment mechanism also includes a second adjustment module 2. The second adjustment module 2 is disposed between the cabinet door 4 and the box door 3, and is used to adjust the position of the cabinet door 4 relative to the box door 3 along the thickness direction of the box door 3. The first adjustment module 1 is disposed at the top of the box door 3, and the second adjustment module 2 is disposed at the bottom of the box door 3.

[0075] In this embodiment, a first adjustment module 1 is provided at the top of the cabinet door 3, and a second adjustment module 2 is provided at the bottom of the cabinet door 3. The first adjustment module 1 and the second adjustment module 2 can cooperate with each other to adjust the relative position of the cabinet door 4 and the cabinet door 3, so that when adjusting the position of the cabinet door 4 along the thickness direction of the cabinet door 3, the cabinet door 4 can remain parallel to the cabinet door 3, avoiding the cabinet door 4 from tilting forward or backward relative to the cabinet door 3. Specifically, when the first adjustment module 1 adjusts the position of the cabinet door 4 along the thickness direction of the cabinet door 3, since the first adjustment module 1 is located at the top of the cabinet door 3, the upper part of the cabinet door 4 may tilt forward or backward. At this time, the user can adjust the second adjustment module 2 to adjust the position of the lower part of the cabinet door 4 along the thickness direction of the cabinet door 3, and readjust the cabinet door 4.

[0076] It is understandable that when the first adjustment module 1 adjusts the position of the cabinet door 4 along the width or height direction of the cabinet door 3, the cabinet door 4 can move relative to the second adjustment module 2 with the first adjustment module 1, and the second adjustment module 2 will not restrict the movement of the cabinet door 4 along the width or height direction of the cabinet door 3.

[0077] It is understood that the first adjustment module 1 can also be set at the bottom of the door 3, and correspondingly, the second adjustment module 2 can be set at the top of the door 3. The technical effect is similar to that of the above embodiment, and will not be described again here.

[0078] In some embodiments, such as Figure 5 and Figure 6 As shown, the second adjustment module 2 includes a second mounting base 21 and a fourth adjustment component 22. The second mounting base 21 is configured to connect to the cabinet door 4. The fourth adjustment component 22 is configured to be disposed on the cabinet door 3 and connected to the second mounting base 21. The fourth adjustment component 22 is used to adjust the position of the second mounting base 21 relative to the cabinet door 3 along the thickness direction of the cabinet door 3.

[0079] In this embodiment, by connecting the fourth adjustment component 22 to the cabinet door 3, and installing the second mounting base 21 on the fourth adjustment component 22, which is connected to the cabinet door 4, the fourth adjustment component 22 can directly adjust the position of the second mounting base 21 relative to the cabinet door 3 along the thickness direction of the cabinet door 3. The cabinet door 4 is moved by the second mounting base 21 to adjust the position of the cabinet door 4 in the thickness direction of the cabinet door 3.

[0080] Specifically, in some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the fourth adjustment assembly 22 includes a fifth slider 221, a sixth slider 222, and a third drive assembly 223. The fifth slider 221 is slidably disposed on the door 3 along its width direction. A second guide groove 2211 is formed on the fifth slider 221, and the extension direction of the second guide groove 2211 is angled to the width direction of the door 3. The sixth slider 222 is slidably disposed on the door 3 along its thickness direction. The sixth slider 222 has a second guide portion inserted into the second guide groove 2211 and is capable of sliding along the extension direction of the second guide groove 2211. The sixth slider 222 is connected to the second mounting base 21. The third drive assembly 223 is connected to the fifth slider 221 and is used to drive the fifth slider 221 to slide along the width direction of the door 3.

[0081] In this embodiment, the third drive assembly 223 and the fifth slider 221 are connected by a transmission. The third drive assembly 223 is used to drive the fifth slider 221 to move along the width direction of the door 3. The second guide portion of the sixth slider 222 is inserted into the second guide groove 2211 of the fifth slider 221. The sixth slider 222 is configured to slide only along the thickness direction of the door 3. When the fifth slider 221 slides along the width of the door 3, the sixth slider 222 will move relative to the fifth slider 221 along the second guide groove 2211, thereby sliding relative to the door 3 along the thickness direction, and driving the second mounting base 21 and the cabinet door 4 as a whole to move along the thickness direction of the door 3, thereby adjusting the relative position of the cabinet door 4 and the door 3 along the thickness direction of the door 3.

[0082] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the third drive assembly 223 includes a fourth limiting member and a fourth adjusting screw 2231. The fourth limiting member is configured to be disposed on the door 3. The fourth adjusting screw 2231 is disposed on the fourth limiting member, and the screw of the fourth adjusting screw 2231 is threadedly connected to a fifth sliding member 221. The fourth adjusting screw 2231 has a fourth screw head facing the side of the door 3. The fourth limiting member abuts against both ends of the fourth screw head.

[0083] In this embodiment, by setting the fourth limiting member on the cabinet door 3, the screw of the fourth adjusting screw 2231 and the fifth sliding member 221 are threadedly connected, and the fourth limiting member abuts against both ends of the fourth screw head of the fourth adjusting screw 2231, so as to limit the fourth adjusting screw 2231 in the width direction of the cabinet door 3, so that the user can adjust the position of the fifth sliding member 221 in the width direction of the cabinet door 3 by using the fourth adjusting screw 2231, so as to adjust the position of the cabinet door 4 in the thickness direction of the cabinet door 3. Specifically, the fourth adjusting screw 2231, limited by the fourth limiting member, can only rotate and cannot move along the width direction of the cabinet door 3, allowing the user to tighten the second screw head using tools such as a screwdriver. The fifth sliding member 221 is configured to slide only along the width direction of the cabinet door 3 and will not rotate with the fourth adjusting screw 2231. This allows the fifth sliding member 221 to move along the width direction of the cabinet door 3 under the drive of the threaded engagement, and then drives the sixth sliding member 222 to slide along the thickness direction of the cabinet door 3 via the second guide groove 2211, thereby adjusting the position of the cabinet door 4 in the thickness direction of the cabinet door 3. Simultaneously, by placing the fourth screw head on the side of the cabinet door 3, the second screw head is not obstructed by the cabinet door 4, facilitating tightening by the user. When the user tightens the fourth adjusting screw 2231, the movement range of the fifth sliding member 221 and the sixth sliding member 222 is small, allowing the user to fine-tune the position of the cabinet door 4 relative to the thickness direction of the cabinet door 3.

[0084] In some embodiments, the second adjustment module 2 further includes a second base 23, and the fourth limiting member can be a clamping structure constructed on the second base 23 to clamp the two ends of the fourth screw head and limit the fourth adjusting screw 2231.

[0085] Specifically, in some embodiments, the second base 23 has a third limiting plate 231 and a fourth limiting plate 232 disposed opposite to each other. The first limiting plate 151 has a third through hole corresponding to the fourth adjusting screw 2231, and the fourth limiting plate 232 has a fourth through hole corresponding to the fourth adjusting screw 2231. The fourth adjusting screw 2231 passes through the third through hole, so that the fourth screw head is limited between the third limiting plate 231 and the fourth limiting plate 232, and the fourth screw head is exposed in the fourth through hole so that the user can screw it.

[0086] Specifically, in some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the sixth sliding member 222 is provided with a third hooking part 2221, and the second mounting base 21 is provided with a fourth hooking part 211 adapted to the third hooking part 2221. The fourth hooking part 211 abuts against the opposite sides of the third hooking part 2221 along the thickness direction of the door 3, and there is a movable gap between the fourth hooking part 211 and the third hooking part 2221 along the width direction and the height direction of the door 3.

[0087] In this embodiment, by providing a compatible third hooking part 2221 and a fourth hooking part 211 to the sixth sliding member 222 and the second mounting base 21 respectively, the sixth sliding member 222 and the second mounting base 21 can be hooked together, making it convenient for the user to install the cabinet door 4 onto the box door 3 via the second adjustment module 2. Specifically, the user can first install the structure of the second adjustment module 2, excluding the second mounting base 21, onto the box door 3, then install the second mounting base 21 onto the cabinet door 4, and finally hook the second mounting base 21 onto the sixth sliding member 222.

[0088] Meanwhile, the fourth connecting part 211 abuts against the opposite sides of the third connecting part 2221 along the thickness direction of the cabinet door 3, allowing the second adjustment module 2 to move the second mounting base 21 and the cabinet door 4 along the thickness direction of the cabinet door 3 by sliding the sixth sliding member 222 along the thickness direction of the cabinet door 3. By leaving a movable gap between the fourth connecting part 211 and the third connecting part 2221 along the width and height directions of the cabinet door 3, the second mounting base 21 can slide relative to the sixth sliding member 222 when the first adjustment module 1 adjusts the position of the cabinet door 4 along the width or height direction of the cabinet door 3, without affecting the movement of the cabinet door 4.

[0089] It is understandable that, in order to constrain and limit the movement direction of the fifth slider 221 and the sixth slider 222, the second base 23 is respectively constructed with a limiting structure or a guiding structure adapted to the fifth slider 221 and the sixth slider 222.

[0090] For example, the second base 23 is provided with a second mounting groove extending along the width direction of the door 3, and the fifth slider 221 is slidably disposed in the second mounting groove. A portion of the structure of the sixth slider 222 is located in the second mounting groove and can move along the thickness direction of the door 3.

[0091] Specifically, in some embodiments, such as Figure 6 and Figure 7 As shown, the sixth sliding member 222 includes a second limiting part 2222 and a third hooking part 2221 connected together.

[0092] The second limiting part 2222 has a T-shaped structure, including a transverse part along the width direction of the door 3 and a longitudinal part along the height direction of the door 3. A detachable second limiting block 233 is provided in the second mounting groove. The second limiting block 233 is located at the junction of one side of the transverse part and the longitudinal part, and abuts against the transverse part and the longitudinal part respectively. A second limiting structure 234 is formed on the groove wall of the second mounting groove. The second limiting structure 234 is located at the junction of the other side of the transverse part and the longitudinal part, and abuts against the transverse part and the longitudinal part respectively. The second limiting block 233 is used to cooperate with the second limiting structure 234 to constrain the sixth sliding member 222, so that the sixth sliding member 222 can only move relative to the second base 23 along the thickness direction of the door 3.

[0093] The third hook part 2221 is in the shape of a hook, and the fourth hook part 211 on the second mounting base 21 is provided with a hook groove. The hook groove extends along the width direction of the door 3 and has openings on both sides of the second mounting base 21 along the width direction of the door 3. The hook can slide into the hook groove from both sides and hook with the hook groove.

[0094] In some embodiments, such as Figure 5 and Figure 6 As shown, there are two second adjustment modules 2, which are arranged at intervals along the width direction of the door 3.

[0095] Specifically, in some embodiments, a first adjustment module 1 is close to the connection structure between the door 3 and the box body (for ease of explanation, it will be abbreviated as "the second adjustment module 2 at the proximal end" below), and another second adjustment module 2 is far away from the connection structure (for ease of explanation, it will be abbreviated as "the second adjustment module 2 at the distal end" below).

[0096] Among them, such as Figure 5 , Figure 6 and Figure 7 As shown, the proximal second adjustment module 2 can share the third limiting plate 231 and the fourth limiting plate 232 with the distal second adjustment module 2. Specifically, the distal second adjustment module 2 has a through hole corresponding to the fourth adjusting screw 2231 of the proximal second adjustment module 2, so that the fourth adjusting screw 2231 of the proximal second adjustment module 2 can pass through the distal second adjustment module 2 and extend into the second base 23 of the distal second adjustment module 2, so that the fourth screw heads of the two first adjustment modules 1 are located between the third limiting plate 231 and the fourth limiting plate 232 of the distal second adjustment module 2 and exposed on the fourth limiting plate 232, so that the user can adjust the two first adjustment modules 1.

[0097] On the other hand, such as Figure 1As shown, this embodiment of the invention also provides a door assembly, including: a box door 3, a cabinet door 4, and a door adjustment mechanism as provided in any of the above embodiments. The cabinet door 4 is disposed on the outside of the box door 3. The box door 3 and the cabinet door 4 are connected by the door adjustment mechanism.

[0098] In this embodiment, after the cabinet door 4 is installed on the box door 3 through the door adjustment mechanism, the relative positions of the cabinet door 4 and the box door 3 can be adjusted in three directions—height, width, and thickness—by the first adjustment component 12, the second adjustment component 13, and the third adjustment component 14 of the door adjustment mechanism, respectively, so that the relative positions of the cabinet door 4 and the box door 3 can meet the final installation requirements.

[0099] According to the door assembly of the present invention, a door adjustment mechanism is provided on the cabinet door 3. The door adjustment mechanism is connected to the cabinet door 4. The door adjustment mechanism can adjust the relative position of the cabinet door 4 and the cabinet door 3 in three directions of height, width and thickness without disassembling the cabinet door 4, which is more convenient and labor-saving.

[0100] It is understood that since the door adjustment mechanism has the beneficial effects of the above embodiments, the door assembly will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and will not be repeated here.

[0101] In another aspect, embodiments of the present invention also provide a refrigeration device, including: a cabinet and a door assembly as provided in any of the above embodiments. The cabinet is configured to be fitted into a cabinet. The door 3 is rotatably connected to the cabinet.

[0102] In this embodiment, the cabinet has an inner cavity for storing items. The door assembly includes a cabinet door 3, a cabinet door 4, and a door adjustment mechanism. The cabinet door 3 and the cabinet are rotatably connected to allow opening and closing of the inner cavity. The cabinet door 4 is installed on the cabinet door 3.
