Description

Technical Field

[0001] The present application relates to the technical field of refrigeration appliances, and in particular to a refrigeration appliance. Background Art

[0002] In existing refrigeration appliances, a push-pull drawer is usually provided in the storage chamber for users to store food or other items that need to be refrigerated or frozen in categories. In order to keep fresh, a cover is usually provided on the drawer to isolate the stored items in the drawer from the external environment. However, the drawers with cover in existing refrigeration appliances are either designed to be open at the front or to be pulled out together with the drawer. This design makes the cover always within the user's visible range during the use of the drawer, so it is necessary to specially consider the industrial aesthetics of the cover itself, thereby increasing the design and manufacturing costs. Utility Model Content

[0003] In view of this, the purpose of the embodiment of the present application is to provide an improved refrigeration appliance, comprising: an appliance body defining at least one storage chamber and a storage device arranged in the storage chamber, wherein the storage device comprises: a main structure arranged in the storage chamber in a push-pull manner, the main structure defining at least one storage space and having an opening that opens upward; a sealing member arranged at the opening; a cover plate structure, the cover plate structure being suitable for pressing the sealing member to hermetically seal the opening; and a linkage assembly, the linkage assembly being suitable for being triggered by a user to linkage unlock or lock the cover plate structure so that the cover plate structure remains in the storage chamber during the unlocking or locking process. Thus, it is ensured that the cover plate structure for hermetically sealing the main structure will not be pulled out of the storage chamber together with the main structure and exposed to the user's line of sight, so there is no need to overly consider the appearance design of the cover plate structure and the parts that may be located thereon, which particularly reduces the complexity of design and manufacturing, thereby saving costs.

[0004] According to an optional embodiment, the linkage assembly includes an operating mechanism suitable for a user to operate to trigger the unlocking or locking process of the cover structure and a locking mechanism that cooperates with the operating mechanism, and the locking mechanism acts on the cover structure. Thus, through the specially arranged operating mechanism and locking mechanism, the user can conveniently lock or unlock the cover structure according to his or her own needs, thereby improving the user experience.

[0005] According to an optional embodiment, the linkage assembly further comprises a force-applying mechanism directly or indirectly fixed to the device body, and the force-applying mechanism applies force to the locking mechanism so that it has a tendency to unlock the cover structure. Thus, the force-applying mechanism fixed to the device body can provide force assistance for unlocking the cover structure, making it easier for the user to perform the unlocking operation.

[0006] According to an optional embodiment, at least most of the locking mechanism is retained in the storage chamber. Here, the term "at least most of" should be understood as occupying more than 80%, preferably more than 90%, and particularly preferably more than 95% of the total volume. As a result, the number of components that can fall into the user's field of vision is further reduced, thereby saving technical costs in design and manufacturing.

[0007] According to an optional embodiment, the force-applying mechanism is a spring in a stretched state, one end of which is directly or indirectly fixed to the appliance body and the other end acts on the locking mechanism. Thus, the spring in a stretched state ensures that the locking mechanism always has a stable unlocking tendency, further reducing the difficulty of unlocking the cover structure.

[0008] According to an optional embodiment, the linkage assembly further comprises a mounting member for mounting the locking mechanism and / or the force applying mechanism, and the mounting member is fixed to the device body. Thus, the design of the mounting member makes the locking mechanism and the force applying mechanism easier to install, thereby improving the production and assembly efficiency of the overall product.

[0009] According to an optional embodiment, during use of the storage device, the locking mechanism is completely retained in the storage chamber, thereby further reducing the number of components that may fall into the user's field of vision, thereby saving technical costs in design and manufacturing.

[0010] According to an optional embodiment, the linkage assembly is configured to allow the main structure to be pulled out only after the cover structure is unlocked, thereby preventing the possibility of misoperation.

[0011] According to an optional embodiment, the linkage assembly is configured to make the unlocking movement direction of the cover structure different from the pulling-out movement direction of the main structure, wherein the unlocking movement direction of the cover structure is particularly upward or obliquely upward. Thus, not only is the space requirement for unlocking the cover structure reduced, but the cover structure is also prevented from falling into the user's field of vision during the unlocking process.

[0012] According to an optional embodiment, the linkage assembly includes two preferably symmetrical locking mechanisms located on both sides of the main structure, each locking mechanism including: a first motion mechanism connected to the cover structure; a second motion mechanism connected to the operating mechanism; and a transmission mechanism suitable for converting the motion of the second motion mechanism into the corresponding motion of the first motion mechanism. Thus, through the two preferably symmetrical left and right locking mechanisms, balanced control of the unlocking or locking motion process of the cover structure can be achieved, reducing the phenomenon of unsmooth motion caused by deflection, thereby ensuring that the unlocking and locking process is smoother and more stable.

[0013] According to an optional embodiment, the first movement mechanism and the cover plate structure are fixedly connected to each other via a detachable locking structure, thereby facilitating the first movement mechanism and the cover plate structure to be manufactured separately, for example, using different materials, and facilitating the disassembly, maintenance or component replacement of the two after assembly.

[0014] According to an optional embodiment, the second movement mechanism and the operating mechanism are linked to each other via a releasable matching structure, thereby providing a more flexible operation experience for the user and facilitating the maintenance and replacement of various components.

[0015] According to an optional embodiment, the transmission mechanism has a first connecting rod and a second connecting rod, and the transmission mechanism changes the relative positions of the first connecting rod and the second connecting rod, especially the relative angle between the first connecting rod and the second connecting rod according to the motion path length of the second motion mechanism, thereby changing the corresponding motion path length of the first motion mechanism. Thus, the unlocking or locking movement of the cover structure is more stable and accurate.

[0016] According to an optional embodiment, the locking structure includes at least one groove provided on the first movement mechanism and at least one protrusion provided on the cover plate structure and suitable for fitting into, especially interference fitting into, the at least one groove. Thus, the locking structure composed of the groove and the protrusion is not only simple in structure and easy to manufacture, but also can provide a stable locking effect.

[0017] According to an optional embodiment, the matching structure includes a cam curve profile portion provided on the operating mechanism and a driven matching profile portion provided on the second motion mechanism, especially provided on the first end of the second motion mechanism and suitable for moving along the cam curve profile portion. Thus, the motion matching structure composed of the cam curve profile portion and the driven matching profile portion can effectively transmit the motion of the operating mechanism to the second motion mechanism, which is conducive to the user's accurate triggering of the unlocking or locking process.

[0018] According to an optional embodiment, the mounting member has a first channel defining a movement path of the second movement mechanism, whereby the first channel provides precise guidance for the movement of the second movement mechanism, thereby ensuring the accuracy and stability of the movement.

[0019] According to an optional embodiment, the first motion mechanism has a second groove defining a motion path of the second connecting rod, whereby the second groove provides precise guidance for the motion of the second connecting rod, thereby ensuring the accuracy and stability of the motion.

[0020] According to an optional embodiment, the first end and the second end of the first connecting rod are respectively coupled to the second motion mechanism and the first motion mechanism, thereby making the motion relationship between the first connecting rod and the first and second motion mechanisms more precise and stable, thereby improving the accuracy and stability of the operation.

[0021] According to an optional embodiment, the first end and the second end of the second connecting rod are respectively coupled to the mounting member and the first motion mechanism, thereby making the motion relationship between the second connecting rod, the mounting member and the first motion mechanism more precise and stable, and improving the accuracy and stability of the operation.

[0022] According to an optional embodiment, the effective transmission length between the first end and the second end of the first connecting rod is equal to the effective transmission length between the first end and the second end of the second connecting rod, thereby ensuring the transmission efficiency and avoiding the transmission error caused by the unequal effective transmission length.

[0023] According to an optional embodiment, the first connecting rod and the second connecting rod are hinged to each other in a central area, thereby making the transmission movement of the two connecting rods more coordinated and improving the stability and accuracy of the operation.

[0024] According to an optional embodiment, the second end of the second movement mechanism is hinged to the first end of the first connecting rod, the second end of the first connecting rod is hinged to the first movement mechanism, the first end of the second connecting rod is hinged to the device body or to a mounting member fixedly connected to the device body, and the second end of the second connecting rod has a roller suitable for rolling in the second channel. In this way, the stable and coordinated movement of each component is ensured, the smoothness of the unlocking and locking process of the cover structure is improved, and the user experience is further improved.

[0025] According to an optional embodiment, the second movement mechanism has at least one rib that cooperates with the first groove, thereby avoiding wear caused by excessive movement of the second movement mechanism in the first groove.

[0026] According to an optional embodiment, the locking structure further comprises at least one introduction groove connected to the at least one groove, thereby ensuring that the process of assembling the groove and the protrusion with each other is smoother and also convenient for disassembling the two.

[0027] According to an optional embodiment, the locking structure includes two grooves respectively provided in two end regions of the first movement mechanism, thereby making the locking relationship between the cover plate structure and the first movement mechanism more stable.

[0028] According to an optional embodiment, at least one protrusion is integrally formed on the cover plate structure, thereby reducing additional components, simplifying the structure, and reducing costs.

[0029] According to an optional embodiment, during the unlocking or locking process, the translational movement of the second motion mechanism drives the first connecting rod, and the driven first connecting rod drives the second connecting rod and the first motion mechanism, so that the first motion mechanism drives the cover plate structure to realize the unlocking or locking motion path. As a result, during the unlocking and locking process, the various motion mechanisms can work in coordination, thereby improving the efficiency and accuracy of unlocking and locking.

[0030] According to an optional embodiment, the storage space of the storage device is suitable for forming a negative pressure inside, thereby facilitating the preservation effect of the stored objects in the storage space.

[0031] According to an optional embodiment, the storage device includes a suction pump disposed on the cover structure. Therefore, since the suction pump is located on the cover structure that is not pulled out together with the main structure, there is no need to specifically consider the appearance of the suction pump, and since the suction pump is basically fixed in the storage chamber of the refrigeration appliance except for the unlocking and locking process, the complexity of its wiring is simplified, thereby saving design and manufacturing costs.

[0032] According to an optional embodiment, the storage device includes a pressure relief valve disposed on the main structure, and the pressure relief valve is particularly suitable for being triggered by the linkage assembly to relieve pressure in the storage space. Thus, for example, when the user triggers the unlocking of the cover structure, the pressure relief valve can be triggered to release pressure in the storage space at the same time, which greatly reduces the difficulty of unlocking the cover structure, especially when there is negative pressure in the storage space.

[0033] According to an optional embodiment, during the use of the storage device, the cover structure is completely kept in the storage chamber. This ensures that the user will not see the cover structure during the entire use of the storage device, so that there is no need to consider the appearance design of the cover structure and the components that may be located thereon, which reduces the complexity of design and manufacturing, thereby saving costs.

[0034] According to an optional embodiment, the refrigeration appliance further comprises a side wall defining the storage chamber and / or an adjustable partition located in the storage chamber, and the linkage assembly is partially fixed to the side wall and / or the adjustable partition. Thus, the storage device can be used as an independent module for different refrigeration appliance design platforms.

[0035] According to an optional embodiment, the refrigeration appliance is configured as a household refrigerator. Therefore, the household refrigerator as a refrigeration appliance particularly has the advantages mentioned in the above embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present application clearer, the present application will be further described in detail in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the scope of protection of the present application, and that the various embodiments may share the same view or multiple views for description, but all features appearing in the same view cannot be interpreted as features that must be possessed by an embodiment.

[0052] Before starting the description, it should be pointed out that, for the sake of convenience, this document may use directional terms or direction terms for description, which are relative to the conventional use state of the refrigeration appliance (especially refrigerator) or the storage device (especially drawer) for the refrigeration appliance. Those skilled in the art can clearly understand this from the description of this application without causing any confusion. In this case, the directional terms and direction terms should not be simply interpreted as the directional or direction in any state. In other words, the directional or positional relationship indicated by the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "longitudinal", "horizontal", "high", "positive", "back" and the like in the description of this application is based on the directional or positional relationship shown in the drawings, which is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0053] In addition, in the description of the present application, the expression "A and / or B" represents all possible combinations of A and B, such as only A, only B, or A and B. The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Here, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0054] For ease of understanding, the description in the background technology section of this application can be reviewed or recalled here. One of the purposes of this application is to provide an improved refrigeration appliance, comprising: an appliance body defining at least one storage chamber and a storage device arranged in the storage chamber, wherein the storage device comprises: a main structure that can be pushed and pulled in the storage chamber, the main structure defining at least one storage space and having an opening that opens upward; a sealing member arranged at the opening; a cover plate structure, the cover plate structure is suitable for pressing the sealing member to hermetically close the opening; and a linkage assembly, the linkage assembly is suitable for being triggered by a user to linkage unlock or lock the cover plate structure so that the cover plate structure remains in the storage chamber during the unlocking and locking process. In the scope of this application, locking of the cover plate structure should be understood in particular as the cover plate structure pressing the sealing member to hermetically close the opening of the main structure, and unlocking should be understood in particular as the cover plate structure causing the sealing member to at least partially relax, that is, no longer pressing the sealing member. The refrigeration appliance provided by the embodiment of the present application ensures that the cover structure used to airtightly seal the main structure will not be pulled out of the storage room together with the main structure and exposed to the user's field of vision. Therefore, there is no need to overly consider the appearance design of the cover structure and the components that may be located thereon, which especially reduces the complexity of design and manufacturing, thereby saving costs.

[0055] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings.

[0056] Figure 1 A schematic diagram of a refrigeration appliance 1000 according to an exemplary embodiment of the present application is shown; Figure 2 1 shows a perspective view of a storage device 900 of a refrigeration appliance 1000 according to an exemplary embodiment of the present application, wherein installation walls 1, 2, and 3 of the refrigeration appliance 1000 on which the storage device 900 is installed are shown in a simplified form. Figure 1 and Figure 2 And the subsequent partial drawings show an xyz coordinate system, wherein x represents the width direction of the refrigeration appliance 1000 or the storage device 900, y represents the height direction of the refrigeration appliance 1000 or the storage device 900, and z represents the depth direction of the refrigeration appliance 1000 or the storage device 900 pointing from front to back.

[0057] like Figure 1 As shown, the refrigeration appliance 1000 is exemplarily configured as a household refrigerator, which includes an appliance body 800 (also referred to as a refrigerator body) defining at least one storage chamber 1001 and at least one storage device 900 disposed in the storage chamber 1001. Figure 1 The refrigerator door is hidden in the figure, from which it can be clearly seen that the refrigeration appliance 1000 includes two upper and lower storage chambers 1001 and the storage device 900 located therein. Figure 1 On the one hand, two storage devices 900 are shown as being arranged side by side in the horizontal direction (i.e., in the width direction x) in the upper storage room 1001, and the two storage devices 900 are shown as having different sizes; on the other hand, two storage devices 900 are shown as being stacked in the vertical direction (i.e., in the height direction y) in the lower storage room 1001, and the two storage devices 900 are shown as having the same size. However, it should be understood that except for Figure 1 In the layout shown, the storage device 900 as an independent module can have more other layout possibilities in the storage chamber 1001 of the refrigeration appliance 1000 .

[0058] from Figure 1It can be seen that the appliance body 800 of the refrigeration appliance 1000 includes a side wall 700 defining an upper and lower storage chamber 1001. Optionally, the appliance body 800 may further include an adjustable partition 600 located in the storage chamber 1001, such adjustable partition 600 may be arranged in the storage chamber 1001 in a manner that can be raised and lowered and / or detachably mounted, and may be provided with a mounting portion (such as a mounting hole, etc.) when necessary for mounting the slide rail of the storage device 900 or other components that need to be fixedly mounted with the appliance body 800. Thus, as will be described in detail below, the linkage assembly 940 of the storage device 900 may be directly fixed to the side wall 700 and / or the adjustable partition 600, for example, through the mounting member 400.

[0059] like Figure 2 As shown, the storage device 900 is installed on the installation walls 1, 2, and 3 of the refrigeration appliance 1000. Figure 1 , Figure 2 The schematically shown mounting walls 1, 2, 3 should be understood as part of the refrigerator liner. For example, the mounting wall 2 can be understood as Figure 1 One of the side walls 700 can be optionally understood as an adjustable partition 600, and the installation walls 1 and 3 can be understood as defining the upper wall or lower wall of the storage room 1001, or upper and lower shelves for dividing the storage room 1001 or placing stored items. As will be described in detail below, since the cover structure 930 of the storage device 900 needs to be unlocked, for example, upward or obliquely upward, there should be a certain gap between the installation wall 1 and the storage device 900.

[0060] from Figure 2 Combination Figure 1 It can be seen that the storage device 900 does not need to be provided with a large outer compartment outside the drawer as in the prior art. Such a large outer compartment in the prior art has various components such as the drawer body and the slide rails inside and must have a large gap. In addition, the volume occupied by such a large outer compartment itself greatly limits the storage space of the drawer itself in the storage room. Different from this, the storage device 900 does not need to be provided with such a large outer compartment, but can be used as an independent module in different refrigeration appliance design platforms, for example, it can be directly combined with the side wall 700 or the adjustable partition 600 for installation and use.

[0061] Figure 3 A perspective view of a storage device 900 of a refrigeration appliance 1000 according to an exemplary embodiment of the present application is shown; Figure 4 Shows Figure 3 A partial perspective view of the storage device 900 is shown; Figure 5 Shows Figure 3 Another partial perspective view of the storage device 900 is shown.

[0062] like Figure 3 Combination Figure 4As shown, the storage device 900 includes a main structure 910 that can be pushed and pulled in the storage room 1001. The main structure 910 is, for example, Figure 3 The slide rail 1002 shown can be pulled out and pushed into the storage chamber 1001 by the user in the depth direction z. Figure 4 As shown, the main structure 910 defines a storage space 911. In an embodiment not shown according to the present application, the main structure 910 may also define a plurality of storage spaces 911, for example, separated by a partition plate. Here, the main structure 910 has an opening 912 that opens upward, and a sealing member 920 is provided at the opening 912. Figure 4 The seal 920 formed on the main structure 910 and surrounding the opening 912 is exemplarily shown, but it should be understood that the seal 920, for example, configured as a sealing ring, can also be arranged (for example, bonded) at the lower part of the cover plate structure 930 described below (for example, Figure 5 Schematically shown).

[0063] like Figure 5 Combination Figure 3 As shown, the storage device 900 includes a cover plate structure 930, which is suitable for compressing the seal 920 to hermetically seal the opening 912 of the main structure 910. In order to unlock or lock the cover plate structure 930 to release or close the opening 912, the storage device 900 also includes a linkage assembly 940, which is triggered by the user to unlock or lock the cover plate structure 930 in a linkage manner. During the use of the storage device 900, for example, during the entire process of the user unlocking, pulling out, accessing stored items, pushing in, and locking the storage device 900, the cover plate structure 930 always remains in the storage chamber 1001, and does not move with the main structure 910, and in particular, will not be pulled out by the user and fall into the user's field of vision.

[0064] from Figure 3It can be seen that the linkage assembly 940 specifically includes an operating mechanism 100 and a locking mechanism 200. The operating mechanism 100 may include a handle portion 101 for direct manipulation by a user. The locking mechanism 200 cooperates with the operating mechanism 100 and acts on the cover structure 930. The locking mechanism 200 itself is fixed to the appliance body 800 of the refrigeration appliance 1000, for example, through a mounting member 400. Therefore, the user can trigger the locking mechanism 200 to unlock or lock the cover structure 930 by, for example, rotating the handle portion 101. In order to facilitate the unlocking process of the cover structure 930 by the user, the linkage assembly 940 may further include a force applying mechanism 300, which is, for example, a spring in a stretched state, one end of which is fixed to the appliance body 800 or to the mounting member 400 and the other end acts on the locking mechanism 200, so as to always apply a pulling force to the locking mechanism 200 (as shown in the figure, a backward pulling force in the depth direction z). When the operating mechanism 100 also applies a pulling force to the locking mechanism 200 (as shown in the figure, it is a pulling force forward in the depth direction z), that is, when the storage device 900 is in a closed or non-use state, the locking mechanism 200 itself maintains a force balance. When the user needs to use the storage device 900, he can first operate the operating mechanism 100 of the linkage assembly 940, such as its handle 101, so that the operating mechanism 100 no longer applies a pulling force to the locking mechanism 200. At this time, the locking mechanism 200 itself no longer maintains a force balance, but the backward pulling force of the force-applying mechanism 300 in the depth direction z is its main function, thereby automatically unlocking the cover structure 930. After the cover structure 930 is unlocked, the main structure 910 is allowed to be pulled out. The specific working principle of the locking mechanism 200 of the linkage assembly 940 will be described in detail in conjunction with the following drawings. It should be noted that in addition to the mechanical linkage method shown in the drawings of the present application, in an embodiment not shown in the present application, the linkage component 940 can also use, for example, an electric method to unlock or lock the cover structure 930 in a linkage manner.

[0065] from Figure 5It can be seen that the linkage assembly 940 may include two locking mechanisms 200 respectively located on both sides of the main structure 910 (i.e., opposite to each other in the width direction x), and the two locking mechanisms 200 are preferably mirror-symmetrical to each other, and each locking mechanism 200 may include a first motion mechanism 210, a second motion mechanism 220, and a transmission mechanism 230. Here, the second motion mechanism 220 is connected to the operating mechanism 100, more specifically, they are linked to each other through a releasable matching structure 80, and the first motion mechanism 210 is connected to the cover structure 930, more specifically, they are fixedly connected to each other through a detachable locking structure 90. When the operating mechanism 100 triggers the second motion mechanism 220, the movement of the second motion mechanism 220 is transmitted to the first motion mechanism 210 through the transmission mechanism 230, so that the first motion mechanism 210 drives the cover structure 930 to perform unlocking or locking movement along a predetermined direction.

[0066] from Figure 5 It can also be seen that the transmission mechanism 230 has a first link 10 and a second link 20. The working principle of the transmission mechanism 230 is, for example, to change the relative positions of the first link 10 and the second link 20 according to the movement path length ΔL of the second motion mechanism 220 (especially to change the relative angle Δα when the first link 10 and the second link 20 are hinged to each other as shown in the figure), and thereby change the corresponding movement path length ΔH of the first motion mechanism 210. Figure 5 The corresponding motion path length ΔH of the first motion mechanism 210 is shown as a vertical motion path in the height direction y, but in fact, it can also be slightly deviated from the height direction y and tilted or bent. But in general, the unlocking or locking motion direction of the cover structure 930 driven by the first motion mechanism 210 is different from the pulling out or pushing in motion direction of the main structure 910, thereby achieving mutual decoupling between the motion of the cover structure 930 itself and the motion of the main structure 910, thereby ensuring that the cover structure 930 will not be pulled out together with the main structure 910.

[0067] Figure 6 A partial exploded view of a storage device 900 according to an exemplary embodiment of the present application is shown, wherein a front panel 970 of the storage device 900 is shown in a separated form; Figure 7 Shows Figure 6 A is a partial enlarged view shown, in which, for comparison, Figure 7 The detail view shown is at a slightly different angle than Figure 6 And the front panel 970 is not shown in a separated form.

[0068] like Figure 6 Combination Figure 3As shown, the storage device 900 may further include a front panel 970 , which together with the handle portion 101 of the operating mechanism 100 forms the front side of the storage device 900 to cover unnecessary components, thereby enhancing the industrial aesthetics.

[0069] from Figure 6 It can be seen that the storage device 900 is closed as a whole, and the storage space 911 of such storage device 900 is particularly suitable for forming negative pressure inside, that is, the storage device 900 is configured as a vacuum drawer or a negative pressure drawer. To this end, the storage device 900 includes a suction pump 950, and the suction pump 950 itself and its related wiring components are preferably arranged on the cover structure 930 that is not pulled out together with the main structure 910. In the case where the storage device 900 is configured as a vacuum drawer or a negative pressure drawer, since the storage device 900 as a whole (especially its main structure 910 and the cover structure 930) need to withstand a large pressure and are easily deformed, the storage device 900 (especially its main structure 910 and the cover structure 930) is preferably made of hard plastic or metal, and further preferably includes a plurality of reinforcing ribs as shown in the figure, which can especially prevent the storage device 900 from being deformed and damaged. The vacuum drawer or negative pressure drawer should be understood as having an internal pressure less than atmospheric pressure, thereby slowing down the oxidation rate of the stored items or reducing the chance of microbial contamination, thereby reducing the possibility of the stored items spoiling. The suction pump 950, for example, has a sensing element, and the suction pump 950 starts working when the sensing element detects that the storage device 900 is completely closed, which is achieved, for example, by program control.

[0070] from Figure 6 It can also be seen that the storage device 900 may include a pressure relief valve 960 on the main structure 910, which is configured so that when the handle portion 101 is turned, a blocking head made of hard plastic is simultaneously pulled out from the orifice made of silicone of the main structure 910. The pressure relief valve 960 is particularly suitable for relieving pressure in the storage space 911 under the triggering of the operating mechanism 100 of the linkage assembly 940. For example, when the user directly operates the operating mechanism 100, especially when the handle portion 101 of the operating mechanism 100 is directly turned outward, the connecting rod mechanism 102 of the operating mechanism 100 will drive the pressure relief valve 960 that originally hermetically closes the pressure relief hole on the front side of the main structure 910 to open, thereby achieving pressure relief. This is beneficial to first relieve pressure before the cover plate structure 930 moves relative to the appliance body 800 of the refrigeration appliance 1000, or before the cover plate structure 930 performs an unlocking movement toward the opening 912 away from the main structure 910, so as to facilitate the subsequent operation process. On the other hand, since the sealed storage space 911 is suddenly depressurized, a sound is emitted, which in particular reminds the user that the depressurization effect has been achieved, thereby proving that the vacuum chamber is working.

[0071] Figure 6 Combination Figure 7 The second movement mechanism 220 of the locking mechanism 200 and the operating mechanism 100 are shown to be releasably connected to each other in a linked manner. Specifically, the releasable matching structure 80 may include a cam curve profile portion 81 (also referred to in Figure 4 ) and a driven matching contour portion 82 provided on the second motion mechanism 220, the driven matching contour portion 82 is adapted to move along the cam curve contour portion 81, which is similar to the working principle of the cam mechanism. Figure 7 As shown, the driven matching contour portion 82 can be specifically configured as a circular protrusion and is preferably provided on the first end 221 of the second motion mechanism 220. Figure 6 and Figure 7 As shown, when the storage device 900 is in a closed or non-used state, the cam curve profile portion 81 and the driven matching profile portion 82 resist each other. In the process of unlocking the cover structure 930 of the storage device 900, the user first triggers the linkage assembly 940, for example, operates the operating mechanism 100, that is, rotates the handle portion 101 around the x-axis along the first rotation direction as shown in the figure, thereby driving the cam curve profile portion 81 downward to disengage from the driven matching profile portion 82 on the second motion mechanism 220. As described above, at this time, the second motion mechanism 220 itself no longer maintains force balance, but is pulled backward in the depth direction z by the force-applying mechanism 300. Therefore, this backward movement of the second motion mechanism 220 is converted into the unlocking movement of the cover structure 930 driven by the first motion mechanism 210 through the transmission mechanism 230. Correspondingly, after the user has finished using the storage device 900 and pushed the main structure 910 back into the storage chamber 1001, the locking process of the cover structure 930 is implemented as follows: the user also triggers the linkage assembly 940, for example, operates the operating mechanism 100, that is, as shown in the figure, the handle portion 101 is rotated around the x-axis in a second rotation direction opposite to the first rotation direction, thereby driving the cam curve contour portion 81 to re-engage with the driven mating contour portion 82 on the second motion mechanism 220 upward, for example, hooking it from bottom to top to apply a forward pulling force in the depth direction z to it. At this time, the second motion mechanism 220 moves forward in the depth direction z. Therefore, this forward movement of the second motion mechanism 220 is again converted into the locking movement of the cover structure 930 by the first motion mechanism 210 through the transmission mechanism 230, and at the same time, the locking mechanism 200 itself maintains force balance again.

[0072] Figure 8 Shows Figure 5 Exploded perspective view of the structure.

[0073] from Figure 8 It can be seen that the detachable locking structure 90 that fixedly connects the first movement mechanism 210 of the locking mechanism 200 and the cover structure 930 to each other may specifically include at least one groove 91 ( Figure 8 The two protrusions 92 respectively provided in the two end regions of the first movement mechanism 210 and at least one protrusion 92 provided on the cover plate structure 930 (preferably integrally formed thereon) are shown as an example. Figure 8 Two corresponding protrusions 92 are shown as an example, and the protrusions 92 are suitable for fitting into (especially interference fitting into) the corresponding grooves 91, so that the first movement mechanism 210 and the cover plate structure 930 are in a fixed state where they cannot move relative to each other. Figure 8 It can also be seen that the locking structure 90 may further include at least one introduction groove 93 connected to the groove 91, so that the protrusion 92 first enters the introduction groove 93 from top to bottom and then translates in the depth direction z to fit into the corresponding groove 91. Figure 8 The locking structure 90 in the figure only shows an introduction groove 93 by way of example. The design of this single introduction groove 93 reduces the structural complexity of the first motion mechanism 210. In particular, when the first motion mechanism 210 is made of aluminum material, it can be manufactured by simple stamping.

[0074] Fig. 9 Shows Figure 8 A partial enlarged view of the lower left structure shown; Fig.10 Shows Figure 8 A partial enlarged view of the lower right structure shown.

[0075] from Fig. 9 It can be seen that the mounting member 400 has a first groove 401 defining the movement path of the second movement mechanism 220, specifically, an opposing double-sided edge rail. Correspondingly, the second movement mechanism 220 has at least one rib 223 that cooperates with the first groove 401. Fig. 9 and Fig.10 Two ribs 223 located on opposite sides of the second motion mechanism 220 are shown (see also Figure 7 (partial enlarged view).

[0076] from Fig.10 It can be seen that the first motion mechanism 210 has a second groove 212 that limits the motion path of the second connecting rod 20, which is specifically a rectangular structure with one side closed and one side open. The closure of one side of the second groove 212 is beneficial to prevent the second connecting rod 20 from accidentally slipping, while the opening on the other side makes the movement of the second connecting rod 20 smoother.

[0077] from Fig.10 It can also be seen that the second end 22 of the second connecting rod 20 has a roller 23 suitable for rolling in the second groove 212 , which is similar to the movement of a roller push rod, so it is not easy to get stuck in the second groove 212 .

[0078] like Fig. 9 and Fig.10As shown, the first connecting rod 10 and the second connecting rod 20 are hinged to each other in the central area, wherein the first connecting rod 10 is connected between the second motion mechanism 220 and the first motion mechanism 210 and forms a motion coupling relationship with them respectively, specifically: the first end 11 of the first connecting rod 10 is hinged to the second motion mechanism 220 (for example, the second end 222 of the second motion mechanism 220), and the second end 12 of the first connecting rod 10 is hinged to the first motion mechanism 210. The second connecting rod 20 is connected between the appliance body 800 of the refrigeration appliance 1000 (or the mounting member 400 fixedly connected to the appliance body 800) and the first motion mechanism 210 and forms a motion coupling relationship with them respectively, specifically: the first end 21 of the second connecting rod 20 is hinged to the appliance body 800 of the refrigeration appliance 1000 (or the mounting member 400 fixedly connected to the appliance body 800), and the second end 22 of the second connecting rod 20 has a roller 23 suitable for rolling in the second channel 212 of the first motion mechanism 210. Here, the effective transmission length between the first end 11 and the second end 12 of the first connecting rod 10 is preferably equal to the effective transmission length between the first end 21 and the second end 22 of the second connecting rod 20. In the scope of the present application, the kinematic coupling of one component with another component should be understood in particular as the possibility of relative movement of the two components only in certain degrees of freedom and not in the remaining degrees of freedom, so that the movement of one component can cause the corresponding movement of the other component.

[0079] exist Fig. 9The thick arrow schematically shows the unlocking process triggered by the operating mechanism 100: in combination with the above, the user can trigger the second motion mechanism 220 to first perform a backward translation movement L0 by operating the operating mechanism 100, and then drive the first end 11 of the first link 10 to rotate counterclockwise by an angle α1 relative to the second motion mechanism 220 as shown in the figure, and then drive the second end 12 of the first link 10 to rotate counterclockwise by an angle α2 relative to the first motion mechanism 210 as shown in the figure. At the same time, since the second link 20 is hinged to the first link 10 in the central area, the second link 20 itself is also relative to the first link 10 as shown in the figure. As shown, the first end 21 of the second link 20 is hinged to the device body 800 (or hinged to the mounting member 400 fixedly connected to the device body 800), so the second end 22 of the second link 20 is rotated clockwise by an angle α4 relative to the first motion mechanism 210 and translated backward L1 in the second slot 212, thereby mainly through the second end 12 of the first link 10 rotating by an angle α2 and the second end 22 of the second link 20 rotating by an angle α4, so that the first motion mechanism 210 drives the cover plate structure 930 to perform an unlocking movement upward or obliquely upward, which is exemplarily represented by a vertical upward arrow H0. In this unlocking process, the first link 10 and the second link 20 are close to each other, so that the first motion mechanism 210 is moved away from the second motion mechanism 220 and the device body 800 (or hinged to the mounting member 400 fixedly connected to the device body 800) in the height direction y to achieve the unlocking movement.

[0080] Correspondingly, in Fig.1010. The locking process triggered by the operating mechanism 100 is schematically shown by a thick arrow in the figure: in combination with the above, the user can operate the operating mechanism 100 to trigger the second motion mechanism 220 to first perform a forward translation movement L0, and then drive the first end 11 of the first link 10 to rotate clockwise by an angle α1 relative to the second motion mechanism 220 as shown in the figure, and then drive the second end 12 of the first link 10 to rotate clockwise by an angle α2 relative to the first motion mechanism 210 as shown in the figure. At the same time, since the second link 20 is hinged to the first link 10 in the central area, the second link 20 itself is also relative to the first link 10 as shown in the figure. As shown in the figure, the cover plate structure 930 rotates counterclockwise by an angle α3, and since the first end 21 of the second connecting rod 20 is hinged to the device body 800 (or hinged to the mounting member 400 fixedly connected to the device body 800), the second end 22 of the second connecting rod 20 rotates counterclockwise by an angle α4 relative to the first motion mechanism 210 and translates forward L1 in the second groove 212, thereby mainly through the second end 12 of the first connecting rod 10 rotating by an angle α2 and the second end 22 of the second connecting rod 20 rotating by an angle α4, so that the first motion mechanism 210 drives the cover plate structure 930 to perform a locking movement downward or obliquely downward, which is exemplarily represented by a vertical downward arrow H0. In this locking process, the first connecting rod 10 and the second connecting rod 20 move away from each other, thereby causing the first motion mechanism 210 to approach the second motion mechanism 220 and the device body 800 (or hinged to the mounting member 400 fixedly connected to the device body 800) in the height direction y to achieve the locking movement.

[0081] Fig.11 FIG. 8 shows an exemplary perspective view of the storage device 900 when it is unlocked. Fig.11 As shown, the storage device 900 is in an unlocked state after being operated, for example, by a user acting on the handle portion 101 of the operating mechanism 100. At this time, the operating mechanism 100 and the second movement mechanism 220 of the locking mechanism 200 are disengaged as described above, that is, they are no longer Figure 7 The structures 910 and 911 are shown as resisting each other but moving away from each other to allow the cover structure 930 to release the opening 912 of the main structure 910 .

[0082] Fig.12 Shown based on Figure 2 A perspective view of a storage device 900 with the main structure 910 partially pulled out. Fig.12 As shown, after unlocking, the main structure 910 of the storage device 900 can be pulled out. At this time, the handle portion 101 of the operating mechanism 100 can be reset to a state in the same plane as the front panel 970 by, for example, an internal spring to improve the overall appearance of the storage device 900.
