Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigerator. Background Technology

[0002] In existing technology, the water box uses a push-spring mechanism for horizontal locking and unlocking. On one hand, this push-spring locking mechanism is unstable, relying on elastic force and a latch to lock. When the refrigerator arrives at the user's home after shipping, the push-spring locking structure is easily damaged by transport vibrations, causing the water box to pop out immediately when the refrigerator door is opened. On the other hand, the push-spring unlocking mechanism causes the refrigerator door to move backward under the pushing force. When the refrigerator is embedded in a kitchen cabinet or placed against a wall, the door may be damaged by hitting the cabinet or wall. Furthermore, when switching from the locked to the unlocked state, the user needs to press the humidifier box first and then pull it out; this requires two actions, which is cumbersome. Summary of the Invention

[0003] This application provides a refrigerator in which the second locking part cooperates with the first locking part so that the unlocking direction is consistent with the direction of pulling out the humidifier box, so that the user can complete the two operations of unlocking and pulling out the humidifier box with one action.

[0004] In a first aspect, a refrigerator is provided, comprising: The container defines a storage compartment with an access opening; A door is rotatably connected to the housing to open or close the loading / unloading port; the door includes a rear wall near the housing when the door is closed. Humidification device, including: A support seat, which is installed on the rear wall of the door; The humidifier box is detachably mounted on the support base; Locking components, which include: A first locking part is located at one end of the support near the rear wall of the door; the first locking part includes: A connecting rod, which is connected to the support seat and extends away from the rear wall of the door; Two hook-on parts are located at the end of the connecting rod away from the rear wall of the door, and are situated on opposite sides of the connecting rod; A second locking part is located at one end of the humidifier box near the rear wall of the door; the second locking part includes: Two locking hooks are rotatably connected to the humidifier box; the locking hooks are used to engage with the hook-on part on the corresponding side; A reset component, one end of which is connected to one of the locking hooks and the other end of which is connected to the other locking hook; The unlocking component is simultaneously hooked and connected to one end of each of the two locking hooks away from the hooking part; When the first locking part and the second locking part transition from the locked state to the unlocked state, the unlocking member moves away from the hook part and drives the two locking hooks to rotate simultaneously, causing the locking hooks to separate from the hook parts on the corresponding sides, while simultaneously stretching the reset member.

[0005] The above technical solution, on the one hand, unlocks the first and second locking parts when the unlocking component moves away from the hooking part, facilitating user operation. On the other hand, after the unlocking action is completed, the two locking hooks rotate under the action of the reset component to reset them to the locked state. When the humidifier box is installed on the support, the hooking part of the first locking part and the two locking hooks work together to pull the reset component to open the two locking hooks; and when the hooking part moves to the side where the corresponding locking hook is away from the back wall of the door, the locking hook is reset under the action of the reset component, so that the hooking part and the corresponding locking hook are hooked together to complete the locking, thereby locking the humidifier box and the support. The above locking process is completed simultaneously when the humidifier box is installed on the support, reducing the user's extra locking action, making it convenient and quick.

[0006] In some embodiments, the unlocking element includes: The unlocking lever extends in the same direction as the connecting lever; Two hooks are provided at one end of the unlocking rod near the connecting rod, and are located on opposite sides of the unlocking rod; The hook portion is used to hook and connect with the end of the lock hook on the corresponding side away from the attachment portion.

[0007] The above technical solution, on the one hand, involves the hook portion of the unlocking component engaging with the end of the corresponding lock hook. When the unlocking component moves away from the rear wall of the door, the hook portion rotates the lock hook, causing it to separate from the corresponding engagement portion, thus unlocking the device. On the other hand, the resetting component, by resetting the lock hook, moves the hook portion closer to the rear wall of the door, resetting the second locking component to the locked state. The hook portion and lock hook are connected, allowing either the hook portion or the lock hook to move by moving the other, thus completing the locking and unlocking transition.

[0008] In some embodiments, the unlocking element includes: An unlocking block is located at the end of the unlocking rod away from the hook; the unlocking block extends to the side away from the top of the humidifier box and protrudes from the humidifier box.

[0009] The above technical solution has two advantages: firstly, the unlocking block extends out of the humidifier box for easy user operation; secondly, the unlocking block is located at the bottom of the humidifier box, keeping it out of the user's sight and avoiding any reduction in the overall aesthetics of the humidifier box due to its placement.

[0010] In some embodiments, the humidifier box includes: Box body; A bottom cover, located on the bottom wall of the box body away from its top; The bottom cover and the bottom wall of the box together define a connected receiving portion and a guide portion; wherein, the guide portion is located on the side of the receiving portion away from the rear wall of the door; The two locking hooks and the two hook portions of the unlocking member are located within the receiving portion; The unlocking lever is installed inside the guide section and is movable relative to the guide section.

[0011] In the above technical solution, the bottom cover and the bottom wall of the box body together define a connected receiving part and a guiding part; the two locking hooks and two hooking parts of the second locking part are in the receiving part, and the unlocking rod is in the guiding part, so that the second locking part can be hidden and does not occupy the water storage space of the box body.

[0012] In some embodiments, baffles are provided on both oppositely arranged walls of the receiving portion; The stop on one of the walls is located on the side of the adjacent lock hook away from the other lock hook, and is used to cooperate with the hook part on the corresponding side to limit the limit position of the unlocking rod to move towards the rear wall of the door.

[0013] The above technical solution, on the one hand, limits the maximum position of the unlocking member's movement towards the rear wall of the door, preventing the unlocking rod from moving too far towards the door body, thus increasing the unlocking stroke during unlocking. On the other hand, the block limits the maximum position of the unlocking member's movement towards the rear wall of the door, thereby limiting the maximum rotation angle of the two locking hooks, and thus limiting the maximum position of the two locking hooks relative to the rear wall of the door, preventing the two locking hooks from extending out of the receiving part.

[0014] In some embodiments, when the unlocking lever moves away from the rear wall of the door to the unlocking position, the unlocking block abuts against the end wall of the guide portion away from the rear wall of the door.

[0015] In the above technical solution, when the unlocking lever moves to the unlocking position, the unlocking block, which is subjected to external force, abuts against the guide part, making the subsequent pull-out action of separating the humidifier box from the support seat by continuing to apply external force to the unlocking block more stable and smooth.

[0016] In some embodiments, When the unlocking lever moves away from the back wall of the door to the unlocking position, the distance between the unlocking block and the edge of the bottom wall of the humidifier box away from the back wall of the door is denoted as the moving distance S1; wherein, 10mm≤S1≤30mm.

[0017] In the above technical solution, when S1 < 10mm, the distance between the unlocking block in the unlocked position and the edge of the bottom wall of the humidifier box away from the back wall of the door is too small. When the user pulls the unlocking block and presses the side wall of the humidifier box away from the back wall of the door, the two forces are too close together, resulting in poor support for the humidifier box that has at least partially moved out of the support. Especially when the humidifier box is about to be completely moved out of the support, it is necessary to support the humidifier box with the other hand in time to remove the humidifier box from the support.

[0018] When S1 > 30mm, the distance between the unlocking block in the unlocked position and the edge of the bottom wall of the humidifier box away from the rear wall of the door is too large. When operating with one hand, the user cannot simultaneously pull the unlocking block and press the side wall of the humidifier box away from the rear wall of the door to continue removing the humidifier box from the support. To complete both the unlocking and detachment operations, the user needs to use both hands, increasing the required actions and making disassembly inconvenient.

[0019] When 10mm≤S1≤30mm, on the one hand, the user can disassemble the humidifier box by pressing the side wall away from the back wall of the door while pulling the unlocking block. On the other hand, the user can provide sufficient support for the humidifier box, which is at least partially removed from the support, while the humidifier box is being removed, thus stably removing the humidifier box from the support.

[0020] In some embodiments, when the first locking part and the second locking part are locked, the position of the unlocking block is recorded as the locking position; at this time, the distance between the unlocking block and the edge of the bottom wall of the humidifier box away from the rear wall of the door is recorded as the locking distance S2; wherein, 10mm≤S2≤50mm.

[0021] In the above technical solution, when S2 < 10mm, the distance between the unlocking block in the locked position and the edge of the bottom wall of the humidifier box away from the back wall of the door is too small. On the one hand, this results in a small travel distance for the unlocking lever during unlocking, easily causing unlocking failure. On the other hand, even if the unlocking action is completed, the small locking distance results in a small distance between the unlocking block in the unlocked position and the edge of the bottom wall of the humidifier box away from the back wall of the door. When the user pulls the unlocking block and presses the side wall of the humidifier box away from the back wall of the door, the two forces act too close together, resulting in poor support for the humidifier box, which has at least partially moved out of the support. Especially when the humidifier box is about to be completely removed from the support, it is necessary to support the humidifier box with the other hand in time to remove it from the support.

[0022] When S2 > 50mm, the distance between the unlocking block in the locked position and the edge of the bottom wall of the humidifier box away from the back wall of the door is too large. This can easily lead to an excessively large distance between the unlocking block in the unlocked position and the edge of the bottom wall of the humidifier box away from the back wall of the door when the user operates with one hand. This makes it impossible for the user to press the side wall of the humidifier box away from the back wall of the door while simultaneously pulling the unlocking block, in order to continue removing the humidifier box from the support. To complete both the unlocking and detachment operations, the user needs to operate with both hands, increasing the required actions and making disassembly inconvenient.

[0023] When 10mm ≤ S2 ≤ 50mm, on the one hand, the unlocking lever has sufficient travel to complete the unlocking action, ensuring effective unlocking. On the other hand, the user can operate with one hand to press the side wall of the humidifier box away from the back wall of the door while pulling the unlocking block, thus disassembling the humidifier box. Furthermore, the user's single-handed action on the humidifier box provides sufficient support for at least part of the humidifier box as it is removed from the support, stably detaching the humidifier box from the support.

[0024] In some embodiments, when the unlocking block abuts against the end wall of the guide portion away from the rear wall of the door, the position of the unlocking block is recorded as the unlocking position; When the first locking part and the second locking part are locked, the position of the unlocking block is recorded as the locked position; The displacement of the unlocking block from the locked position to the unlocked position is denoted as the unlocking distance J; where 4mm≤J≤10mm.

[0025] In the above technical solutions, when J < 4mm, the unlocking distance J is too small, resulting in insufficient travel of the unlocking lever during unlocking, which easily leads to unlocking failure. Furthermore, a small unlocking distance J results in insufficient travel of the unlocking lever, causing an excessive distance between the unlocking block (in the unlocked position) and the edge of the humidifier box's bottom wall away from the rear door wall. This makes it impossible for the user to simultaneously pull the unlocking block and press the side wall of the humidifier box away from the rear door wall while operating with one hand, in order to continue detaching the humidifier box from the support. To complete both the unlocking and detachment operations, the user needs both hands, increasing the required actions and making disassembly inconvenient.

[0026] When J > 10mm, the unlocking distance J is too large, resulting in an excessively large travel of the unlocking lever during unlocking. This causes the distance between the unlocking block in the unlocked position and the edge of the bottom wall of the humidifier box away from the back wall of the door to be too small. When the user pulls the unlocking block while pressing the side wall of the humidifier box away from the back wall of the door, the two forces are applied too close together, resulting in poor support for the humidifier box, which has at least partially moved out of the support. Especially when the humidifier box is about to be completely removed from the support, it is necessary to support the humidifier box with the other hand in time to remove it from the support.

[0027] When 4mm ≤ J ≤ 10mm, on the one hand, the unlocking lever has sufficient travel to complete the unlocking action, ensuring effective unlocking. On the other hand, the user can operate with one hand to press the side wall of the humidifier box away from the back wall of the door while pulling the unlocking block, thus disassembling the humidifier box. Furthermore, the user's single-handed operation provides sufficient support for at least part of the humidifier box as it is removed from the support, stably detaching the humidifier box from the support.

[0028] Secondly, a refrigerator is provided, comprising: The container defines a storage compartment with an access opening; A door is rotatably connected to the housing to open or close the loading / unloading port; the door includes a rear wall near the housing when the door is closed. Humidification device, including: A support seat, which is installed on the rear wall of the door; A humidifier box is detachably mounted on a support; the humidifier box can be removed from the support in a direction away from the rear wall of the door. Locking components, which include: A second locking part is located at one end of the humidifier box near the rear wall of the door; the second locking part includes: Two locking hooks are rotatably connected to the humidifier box; one of the two locking hooks has a guide surface at one end near the rear wall of the door; along the direction from the rear wall of the door to the humidifier box, the guide surface of one locking hook is inclined towards the other locking hook; A reset component, one end of which is connected to one of the locking hooks and the other end of which is connected to the other locking hook; The unlocking component is hooked to one end of two locking hooks away from the hook-up portion; The first locking unit includes: Two hooks are connected to the support base and are used to engage with the locking hooks on the corresponding sides; When the first locking part and the second locking part change from the locked state to the unlocked state, the unlocking member moves away from the hook part, and the unlocking member drives the two locking hooks to rotate simultaneously, so that the locking hooks are separated from the hook parts on the corresponding sides, and at the same time stretches the reset member.

[0029] The above technical solution, on the one hand, unlocks the first and second locking parts when the unlocking component moves away from the hanging part, making it convenient for the user to operate. The unlocking direction is consistent with the direction in which the humidifier box is removed from the support, allowing the user to complete both the unlocking and humidifier box removal from the support with a single directional movement.

[0030] On the other hand, after the unlocking action is completed, the reset component rotates the two locking hooks to reset them to the locked state. When the humidifier box is installed on the support, the hook part of the first locking part and the two locking hooks work together to pull the reset component to open the two locking hooks; and when the hook part moves to the side of the corresponding locking hook away from the back wall of the door, the locking hook is reset by the reset component, so that the hook part and the corresponding locking hook are hooked together to complete the locking, thereby locking the humidifier box and the support. The above locking process is completed simultaneously when the humidifier box is installed on the support, reducing the user's extra locking action and making it convenient and quick.

On the other hand, with the humidifying box 4 located on the door 102, the door 102 is open when the user is installing or removing the humidifying box 4, facilitating user operation for installation or removal.

[0043] In some embodiments of this application, a receiving cavity 30 is formed within the support 3 for installing the humidifier box 4. A disassembly port 31, communicating with the receiving cavity 30, is formed at the end of the support 3 away from the rear wall 1021 of the door. The humidifier box 4 is installed in or removed from the receiving cavity 30 through the disassembly port 31. This technical solution is convenient to install; the humidifier box 4, installed within the receiving cavity 30 of the support 3, provides shielding and protection for the humidifier box 4 installed on the door 102.

[0044] Please refer to some embodiments of this application. Figure 4 As shown, the support 3 includes a base 3a and a cover 3b, which are fixedly connected to form a receiving cavity 30 and a disassembly / removal opening 31. The base 3a has openings on its front and top sides, and the cover 3b is fixed to the top opening of the base 3a, thus forming the receiving cavity 30 and the disassembly / removal opening 31. This technical solution makes the installation of the base 3a and the cover 3b simple and reliable.

[0045] In some embodiments of this application, the humidifying device 200 includes a locking component for locking or unlocking the humidifying box 4 and the support 3.

[0046] Please refer to some embodiments of this application. Figures 4-11 As shown, the locking assembly includes a first locking part 5. The first locking part 5 is located at one end of the support 3 near the rear wall 1021 of the door. The first locking part 5 includes a connecting rod 51 connected to the support 3, and the connecting rod 51 extends away from the rear wall 1021 of the door. In addition, the first locking part 5 includes two hook parts 52, which are located at the end of the connecting rod 51 away from the rear wall 1021 of the door, and are situated on opposite sides of the connecting rod 51.

[0047] The locking assembly includes a second locking part 6 for cooperating with the first locking part 5 to lock or unlock the humidifier box 4 and the support 3. The second locking part 6 is located at one end of the humidifier box 4 near the rear wall 1021 of the door.

[0048] The second locking part 6 includes two locking hooks 61. The two locking hooks 61 are rotatably connected to the humidifier box 4; the locking hooks 61 are used to cooperate with the hook part 52 on the corresponding side.

[0049] The second locking part 6 includes a reset member 62. One end of the reset member 62 is connected to one of the locking hooks 61, and the other end is connected to the other locking hook 61. Optionally, the reset member 62 can be configured as a tension spring.

[0050] The second locking part 6 includes an unlocking member 63, which is simultaneously hooked and connected to the ends of the two locking hooks 61 away from the hooking part 52.

[0051] like Figure 10 A schematic diagram of the structure when the first locking part and the second locking part are in the locked state; Figure 11 This is a schematic diagram showing the structure when the first locking part and the second locking part are unlocked. Figure 10 and Figure 11 In the middle, blue represents the support base, and red lines represent the unlocking components.

[0052] Reference Figures 10-11 When the first locking part 5 and the second locking part 6 transition from the locked state to the unlocked state, the unlocking member 63 moves away from the hook part 52, causing the two locking hooks 61 to rotate simultaneously, separating them from the corresponding hook parts 52. Simultaneously, the resetting member 62 is stretched. At this point, by continuing to move the second locking part 6, the hook part 52 can be moved out of the locking range of the two locking hooks 61. Therefore, the movement of the unlocking member 63 away from the hook part 52 unlocks the first locking part 5 and the second locking part 6, facilitating user operation.

[0053] After the force acting on the unlocking member 63 is released, the resetting member 62 releases its elastic potential energy and retracts its length to drive the two hooks 61 connected to it to rotate, so that the two hooks 61 switch to the closed state.

[0054] On the other hand, when the humidifier box 4 is installed on the support 3, the second locking part 6 approaches the first locking part 5. The hook part 52 of the first locking part 5 acts on the corresponding locking hook 61, causing the two locking hooks 61 to rotate and separate, and simultaneously stretching the reset member 62. As the second locking part 6 moves further closer to the first locking part 5, the two hook parts 52 enter the locking range of the two locking hooks 61. The reset member 62 releases its elastic potential energy and retracts its length, causing the two locking hooks 61 to rotate into a closed state, completing the locking of the two hook parts 52, that is, completing the locking of the first locking part 5 and the second locking part 6, and completing the locking of the humidifier box 4 and the support 3. The above locking process is completed simultaneously during the installation of the humidifier box 4 on the support 3, reducing the user's extra locking operation, making it convenient and quick.

[0055] In some embodiments of this application, the unlocking member 63 includes an unlocking rod 631, which extends in the same direction as the connecting rod 51. Two hook portions 632 are provided at one end of the unlocking rod 631 near the connecting rod 51; the two hook portions 632 are located on opposite sides of the unlocking rod 631. The hook portions 632 are used to hook and connect with the end of the corresponding locking hook 61 away from the hooking portion 52.

[0056] The above technical solution, on the one hand, involves the hook portion 632 of the unlocking member 63 hooking and connecting with the end of the corresponding lock hook 61. When the unlocking member 63 moves away from the rear wall 1021, the hook portion 632 can drive the lock hook 61 to rotate, causing the lock hook 61 to separate from the corresponding hooking portion 52, thus completing the unlocking. On the other hand, under the action of the reset member 62 driving the lock hook 61 to reset, the lock hook 61 drives the hook portion 632, causing the unlocking member 63 to move closer to the rear wall 1021, thus resetting the second locking portion 6 to the locked state. The hook portion 632 and the lock hook 61 are hooked and connected, so that either the hook portion 632 or the lock hook 61 drives the other to move, thereby completing the switching between locking and unlocking.

[0057] In some embodiments of this application, the unlocking component 63 includes an unlocking block 633; ​​the unlocking block 633 is located at the end of the unlocking rod 631 away from the hook portion 632; the unlocking block 633 extends away from the top of the humidifier box 4 and protrudes from the humidifier box 4. With this technical solution, on the one hand, the unlocking block 633 protruding from the humidifier box 4 facilitates user operation; on the other hand, the unlocking block 633 is located at the bottom of the humidifier box 4, keeping it out of the user's sight; thus avoiding a reduction in the overall aesthetics of the humidifier box 4 due to the placement of the unlocking block 633.

[0058] In some embodiments of this application, the humidifier box 4 includes a box body 41 and a bottom cover 42 located on the side of the bottom wall of the box body 41 away from its top. The bottom cover 42 and the bottom wall of the box body 41 together define a communicating receiving portion and a guide portion; wherein, the guide portion is located on the side of the receiving portion away from the rear wall 1021 of the door; two locking hooks 61 and two hook portions 632 of the unlocking member 63 are located in the receiving portion; the unlocking rod 631 is installed in the guide portion and is movable relative to the guide portion.

[0059] In the above technical solution, the bottom cover 42 and the bottom wall of the box body 41 together define a connected receiving part and a guiding part; the two locking hooks 61 and the two hook parts 632 of the second locking part 6 are in the receiving part, and the unlocking rod 631 is in the guiding part, so that the second locking part 6 can be hidden and does not occupy the water storage space of the box body 41.

[0060] In some embodiments of this application, the bottom wall of the box body 41 is recessed in a direction away from the bottom cover 42 to form a first recess 411 and a second recess 412. The first recess 411 and the second recess 412 are connected; the second recess 412 is located on the side of the first recess 411 away from the rear wall 1021 of the door. The bottom cover 42 mates with the bottom wall of the box body 41, and the bottom cover 42 and the first recess 411 together define a receiving portion, and the bottom cover 42 and the second recess 412 together define a guiding portion. In the above technical solution, the first recess 411 and the second recess 412 are formed on the bottom wall of the box body 41, making the bottom surface of the box body 41 after mating with the bottom cover 42 flat, facilitating the installation of the humidifier box 4 into the receiving cavity 30 through the disassembly port 31, ensuring smooth and unobstructed installation.

[0061] In some embodiments of this application, a locking opening 410 is formed at one end of the box body 41 near the rear wall 1021 of the door. The locking opening 410 communicates with the receiving portion (first recess 411); when the humidifier box 4 is installed in the support 3, the first locking part 5 extends into the receiving portion (first recess 411) through the locking opening 410 and locks with the second locking part 6 located in the receiving portion (first recess 411), so that the humidifier box 4 is locked to the support 3. In the above technical solution, the second locking part 6 is completely received in the receiving portion. Through the locking opening 410, the first locking part 5 and the second locking part 6 can complete the locking, so that the second locking part 6 is hidden, which increases the consistency of the overall appearance of the humidifier box 4, increases the internal space of the humidifier box 4, and avoids the reduction of the internal space of the humidifier box 4 by occupying the space of the receiving cavity 30 due to the second locking part 6 being located outside the humidifier box 4.

[0062] In some embodiments of this application, a stop block 43 is provided on each of the two oppositely arranged wall surfaces of the first recess 411; wherein the stop block 43 on any one wall surface is located on the side of the adjacent lock hook 61 away from the other lock hook 61, and is used to cooperate with the hook part 632 on the corresponding side to limit the limit position of the unlocking rod 631 moving towards the rear wall 1021 of the door.

[0063] The above technical solution, on the one hand, limits the extreme position of the unlocking member 63 in the direction closer to the rear wall 1021, preventing the unlocking rod 631 from moving too far towards the door body 102, thus increasing the unlocking stroke during unlocking. On the other hand, the stop block 43 limits the extreme position of the unlocking member 63 in the direction closer to the rear wall 1021, thereby limiting the extreme rotation angle of the two locking hooks 61, and thus limiting the extreme position of the two locking hooks 61 relative to the rear wall 1021, preventing the two locking hooks 61 from extending out of the receiving part.

[0064] In some embodiments of this application, when the unlocking lever 631 moves away from the rear wall 1021 of the door to the unlocking position, the unlocking block 633 abuts against the end wall of the guide portion away from the rear wall 1021. In the above technical solution, when the unlocking lever 631 moves to the unlocking position, the unlocking block 633, under external force, abuts against the guide portion, making the subsequent pull-out action of separating the humidifier box 4 from the support 3 by continuing to apply external force to the unlocking block 633 more stable and smooth.

[0065] In some embodiments of this application, when the unlocking lever 631 moves to the unlocking position away from the rear wall 1021 of the door, the distance between the unlocking block 633 and the edge of the bottom wall of the humidifier box 4 away from the rear wall 1021 is called the moving distance S1; wherein, 10mm≤S1≤30mm.

[0066] In the above technical solution, when S1 < 10mm, the distance between the unlocking block 633 and the edge of the bottom wall of the humidifier box 4 away from the back wall 1021 when in the unlocked position is too small. When the user pulls the unlocking block 633 and presses the side wall of the humidifier box 4 away from the back wall 1021 at the same time, the two forces are too close to each other, resulting in poor support for the humidifier box 4 that has at least partially moved out of the support 3. Especially when the humidifier box 4 is close to being completely moved out of the support 3, it is necessary to support the humidifier box 4 with the other hand in time to remove the humidifier box 4 from the support 3.

[0067] When S1 > 30mm, the distance between the unlocking block 633 in the unlocked position and the edge of the bottom wall of the humidifier box 4 away from the back wall 1021 is too large. When operating with one hand, the user cannot simultaneously pull the unlocking block 633 and press the side wall of the humidifier box 4 away from the back wall 1021 to continue removing the humidifier box 4 from the support 3. To complete both the unlocking and detachment operations, the user needs to use both hands, increasing the required actions and making disassembly inconvenient.

[0068] When 10mm≤S1≤30mm, on the one hand, the user can disassemble the humidifier box 4 by pressing the side wall of the humidifier box 4 away from the rear wall 1021 while pulling the unlocking block 633 with one hand. On the other hand, the user can provide sufficient support for the humidifier box 4, which is at least partially removed from the support 3, while the humidifier box 4 is being removed with one hand, so as to stably remove the humidifier box 4 from the support 3.

[0069] In some embodiments of this application, when the first locking part 5 and the second locking part 6 are locked, the position of the unlocking block 633 is recorded as the locked position; at this time, the distance between the unlocking block 633 and the edge of the bottom wall of the humidifier box 4 away from the door rear wall 1021 is recorded as the locking distance S2; wherein, 10mm≤S2≤50mm.

[0070] In the above technical solution, when S2 < 10mm, the distance between the unlocking block 633 in the locked position and the edge of the bottom wall of the humidifier box 4 away from the back wall 1021 is too small. On the one hand, this results in the unlocking lever 631 having too little travel during unlocking, which can easily lead to unlocking failure. On the other hand, even if the unlocking action is completed, the small locking distance makes the distance between the unlocking block 633 in the unlocked position and the edge of the bottom wall of the humidifier box 4 away from the back wall 1021 too small. When the user pulls the unlocking block 633 and presses the side wall of the humidifier box 4 away from the back wall 1021, the two forces are too close together, resulting in poor support for the humidifier box 4, which has at least partially moved out of the support 3. Especially when the humidifier box 4 is close to being completely removed from the support 3, it is necessary to support the humidifier box 4 with the other hand in time to remove it from the support 3.

[0071] When S2 > 50mm, the distance between the unlocking block 633 in the locked position and the edge of the bottom wall of the humidifier box 4 away from the rear door wall 1021 is too large. This can easily lead to an excessively large distance between the unlocking block 633 in the unlocked position and the edge of the bottom wall of the humidifier box 4 away from the rear door wall 1021 when the user operates with one hand. This makes it impossible for the user to simultaneously pull the unlocking block 633 and press the side wall of the humidifier box 4 away from the rear door wall 1021 to continue removing the humidifier box 4 from the support 3. To complete both the unlocking and detachment operations, the user needs to operate with both hands, increasing the required actions and making detachment inconvenient.

[0072] When 10mm≤S2≤50mm, on the one hand, the unlocking lever 631 has sufficient travel to complete the unlocking action, ensuring effective unlocking. On the other hand, the user can operate with one hand to press the side wall of the humidifier box 4 away from the rear wall 1021 while pulling the unlocking block 633, thus disassembling the humidifier box 4. Furthermore, the user's single-handed action on the humidifier box 4 can provide sufficient support for at least part of the humidifier box 4 as it is removed from the support 3, stably removing the humidifier box 4 from the support 3.

[0073] In some embodiments of this application, when the unlocking block 633 abuts against the end wall of the guide portion away from the rear wall 1021 of the door, the position of the unlocking block 633 is recorded as the unlocking position; When the first locking part 5 and the second locking part 6 are locked, the position of the unlocking block 633 is recorded as the locked position. The displacement of the unlocking block 633 from the locked position to the unlocked position is denoted as the unlocking distance J; where 4mm≤J≤10mm.

[0074] In the above technical solutions, when J < 4mm, the unlocking distance J is too small, resulting in a limited travel distance for the unlocking lever 631 during unlocking, which easily leads to unlocking failure. Furthermore, a small unlocking distance J results in a limited travel distance for the unlocking lever 631, causing an excessive distance between the unlocking block 633 (in the unlocked position) and the edge of the bottom wall of the humidifier box 4 away from the door rear wall 1021. This makes it impossible for the user to simultaneously pull the unlocking block 633 and press the side wall of the humidifier box 4 away from the door rear wall 1021 while operating with one hand, thus preventing the user from detaching the humidifier box 4 from the support 3. Completing both the unlocking and detachment operations requires the user to use both hands, increasing the required actions and making detachment inconvenient.

[0075] When J > 10mm, the unlocking distance J is too large, resulting in an excessively large travel of the unlocking lever 631 during unlocking. This causes the distance between the unlocking block 633 in the unlocked position and the edge of the bottom wall of the humidifier box 4 away from the back wall 1021 to be too small. When the user pulls the unlocking block 633 and presses the side wall of the humidifier box 4 away from the back wall 1021, the two forces are too close together, resulting in poor support for the humidifier box 4, which has at least partially moved out of the support 3. Especially when the humidifier box 4 is close to being completely removed from the support 3, it is necessary to support the humidifier box 4 with the other hand in time to remove it from the support 3.

[0076] When 4mm≤J≤10mm, on the one hand, the unlocking lever 631 has sufficient travel to complete the unlocking action, ensuring effective unlocking. On the other hand, the user can operate with one hand to press the side wall of the humidifier box 4 away from the rear wall 1021 while pulling the unlocking block 633, in order to disassemble the humidifier box 4. Furthermore, the user's single-handed action on the humidifier box 4 can provide sufficient support for at least part of the humidifier box 4 as it is removed from the support 3, stably removing the humidifier box 4 from the support 3.

[0077] In some embodiments of this application, one of the two locking hooks 61 has a guide surface at one end near the rear wall 1021 of the door; along the direction from the rear wall 1021 of the door towards the humidifier box 4, the guide surface of one locking hook 61 is inclined towards the other locking hook 61. This technical solution guides the first locking part 5 between the two locking hooks 61 when the humidifier box 4 is installed on the support 3, making the alignment of the first locking part 5 and the second locking part 6 more precise.
