Description

Technical Field

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

[0002] Refrigerators are primarily used for refrigerating and freezing food to extend its freshness. They are an indispensable household appliance. As people's living standards improve, their demands for refrigerators are also increasing.

[0003] In related technologies, refrigerator drawers are installed in the compartments of the refrigerator body via guide rails, and the drawers are opened and closed by pushing and pulling them. However, opening the drawers is relatively difficult due to factors such as negative pressure, guide rail self-locking, door seal suction, and gravity, which affects the convenience of using the refrigerator. Utility Model Content

[0004] This application provides a refrigerator that makes opening the refrigerator door easier.

[0005] This application provides a refrigerator, which includes:

[0006] The enclosure is constructed to form a refrigeration compartment with an opening at the front.

[0007] A drawer, which can be pulled out and installed in the refrigeration compartment; the drawer includes:

[0008] The drawer body is slidably connected to the side of the refrigeration compartment; the drawer body is constructed to form an upward-opening storage cavity;

[0009] The drawer is fixed to the front side of the drawer body;

[0010] A handle assembly is installed in the drawer; the handle assembly includes:

[0011] Shaft;

[0012] A handle is rotatably mounted to the drawer via the pivot; the handle has an abutment end and a handle end opposite each other along its extension direction, the abutment end being used to abut against the front side of the cabinet;

[0013] The pivot is located between the abutment end and the handle end; the lever arm of the abutment end is smaller than the lever arm of the handle end.

[0014] The portion of the handle between the pivot and the handle end forms a pressure-bearing surface, which is configured to abut against the front side of the drawer so that the drawer can be pulled outward by the handle.

[0015] In this embodiment, a handle assembly is provided on the drawer door for opening the drawer. The handle assembly includes a handle and a pivot. The handle is rotatably connected to the drawer via the pivot, forming a lever structure that makes opening the drawer easier. Furthermore, the handle is also constructed to form a pressure-bearing surface that abuts against the front side of the drawer, allowing the drawer to be pulled outwards via the handle. When the pressure-bearing surface abuts against the front side of the drawer, it serves two purposes: firstly, it limits the outward rotation angle of the handle, i.e., it limits the rotational travel of the handle; secondly, after the drawer is pushed open by the top, the abutment between the pressure-bearing surface and the front side of the drawer allows the force applied by the handle to pull the drawer outwards to be transmitted through the pressure-bearing surface. This reduces the force exerted on the pivot, resulting in a longer service life for the pivot and eliminating the need for a thicker pivot, thus making the handle assembly structure more compact.

[0016] In some embodiments of this application, the handle includes:

[0017] A handle portion, one end of which is configured to form the handle end;

[0018] A pressure plate is connected to the other end of the handle portion; the pressure plate is located on the rear side of the handle portion, and the rear surface of the pressure plate forms the pressure-bearing surface;

[0019] The mounting part is located on the rear side of the pressure plate, and the mounting part is configured to form the abutment top away from the rear end of the pressure plate; the mounting part is rotatably connected to the drawer via the pivot.

[0020] In this embodiment, the handle is designed to facilitate user operation by providing a handle portion; a pivot is mounted by providing a mounting portion; and a pressure plate is provided to form a pressure-bearing surface, thereby abutting against the front side of the drawer. This allows the drawer-pulling force acting on the handle to be transmitted to the drawer through the pressure-bearing surface, reducing the drawer-pulling force acting on the pivot and extending the service life of the handle assembly.

[0021] In some embodiments of this application, the mounting part includes:

[0022] The upper plate is connected to the end of the pressure plate opposite to the handle portion; the end of the upper plate is configured to form the abutment tip.

[0023] The lower plate is connected to the handle, and the lower plate and the upper plate are opposite to each other along the height direction of the drawer and are spaced apart;

[0024] Both the upper plate and the lower plate are rotatably connected to the drawer via the pivot.

[0025] In this embodiment, the mounting part is provided with an upper plate and a lower plate arranged at intervals along the height of the drawer, which are rotatably connected to the drawer via pivots. This provides two rotatable connection points between the mounting part and the pivots, which helps to improve the reliability and stability of the connection between the handle and the pivots and ensures the rotation of the handle relative to the drawer.

[0026] In some embodiments of this application, the rotating shaft includes:

[0027] The first shaft portion, wherein the upper plate portion is rotatably connected to the drawer via the first shaft portion;

[0028] The second shaft portion is coaxially arranged with the first shaft portion; the lower plate portion is rotatably connected to the drawer via the second shaft portion.

[0029] The pivot in this embodiment is provided with two shafts, so that the upper plate is rotatably connected to the drawer through the first shaft and the lower plate is rotatably connected to the drawer through the second shaft. This can ensure sufficient axial fit length and avoid setting an excessively long pivot, which would affect the structural strength.

[0030] In some embodiments of this application, the pivot extends along the height direction of the drawer.

[0031] In this way, the handle rotates in the horizontal plane. When the handle end rotates outward, the top edge rotates inward and abuts against the front side of the drawer. This design ensures the handle's position remains constant along the drawer's height, improving user convenience. Furthermore, along the drawer's width, when the user is facing the drawer, the handle end is located to the right of the top edge, conforming to user operating habits and further enhancing ease of use.

[0032] In some embodiments of this application, the handle portion is configured to form a groove, and the groove extends along the extending direction of the handle portion;

[0033] The handle assembly also includes a pressure-bearing rod, one end of which is rotatably connected to the drawer; the other end of the pressure-bearing rod is provided with a first connecting shaft; the first connecting shaft is inserted into the slide groove;

[0034] When the handle rotates relative to the pivot, the first connecting shaft slides along the slide groove;

[0035] When the pressure-bearing surface abuts against the drawer, the handle also drives the drawer to pull outwards via the pressure-bearing rod.

[0036] The handle assembly of this application embodiment features a pressure-bearing rod. One end of the rod is rotatably connected to the drawer, and the other end has a first connecting shaft inserted into a slide groove. This allows the pressure-bearing rod to move with the handle, preventing it from affecting the handle's rotation. When the pressure-bearing surface abuts against the drawer, the pulling force applied by the user to the handle can be transmitted to the drawer through the pressure-bearing rod, thereby causing the drawer to move outward as a whole.

[0037] In some embodiments of this application, the upper plate portion includes a plate body and a roller, the plate body being connected to the end of the pressure plate opposite to the handle portion; the roller is rotatably mounted on the plate body, and the wheel surface of the roller forms the abutment top.

[0038] In this embodiment, by rotating and installing rollers on the upper plate body, the roller surface abuts against the front side of the cabinet. This allows the rollers to contact the front side of the cabinet during the process of opening the drawer, reducing the friction between the top of the roller and the front side of the cabinet, thus preventing marks from forming on the front side of the cabinet and helping to maintain the appearance of the refrigerator.

[0039] In some embodiments of this application, the top of the drawer is configured to form a front groove wall and a rear groove wall, the front groove wall and the rear groove wall are opposite to each other and spaced apart along the thickness direction of the drawer, and a pull-out groove is formed between the front groove wall and the rear groove wall;

[0040] The front groove wall is provided with a notch to prevent the handle from rotating;

[0041] The rear groove wall is provided with a through-hole that extends through its thickness direction;

[0042] The top abutment abuts against the front side of the box body through the through-hole;

[0043] The pressure-bearing surface is configured to abut against the front side of the rear groove wall;

[0044] When the drawer is closed, the front surface of the handle does not protrude from the front surface of the front groove wall, and there is a gap between the part of the handle and the rear groove wall.

[0045] The above design allows the handle to retract into the drawer slot when the drawer is closed, resulting in a compact handle installation structure and minimal impact on the appearance of the front side of the drawer.

[0046] In some embodiments of this application, the handle structure is formed as follows:

[0047] The mounting cavity is provided with a mounting shaft;

[0048] The passageway is connected to the mounting cavity;

[0049] The handle assembly also includes a torsion spring, the spring body of which is sleeved on the mounting shaft, one torsion arm of which abuts against the cavity wall of the mounting cavity, and the other torsion arm of which extends out through the opening to the outside of the mounting cavity and abuts against the drawer.

[0050] The torsion spring is configured to elastically deform when the handle opens the drawer.

[0051] The handle assembly of this application embodiment uses a torsion spring installed inside the handle's mounting cavity. The two torsion arms of the torsion spring abut against the cavity wall and the drawer, respectively. Furthermore, the torsion spring elastically deforms when the drawer is opened. Thus, after the handle loses the user's operating force, the torsion spring causes the handle to rotate in the opposite direction, automatically returning the handle to the closed state without additional operation.

[0052] In some embodiments of this application, the handle includes an outer shell and an inner liner, the outer shell being configured to form the abutment top and the pressure-bearing surface, and the outer shell being rotatably connected to the drawer via the pivot.

[0053] The inner liner is fixed to the rear side of the outer shell, and the inner liner forms the handle end, and the end of the inner liner forms a protrusion that protrudes away from the outer shell.

[0054] The inner lining is a plastic inner lining, and the outer shell is a metal outer shell.

[0055] The inner lining is made of plastic, which provides a good feel for the user's hands and avoids the burrs and other structural features found in the metal outer casing. The outer casing is made of metal, which provides sufficient structural strength for the handle. Attached Figure Description

[0081] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0082] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0083] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0084] The door opening force of a refrigerator, that is, the force required to open the refrigerator door, is an important indicator of the refrigerator's ease of use and sealing performance. The refrigerator door is usually tightly sealed to the cabinet by a door seal (magnetic sealing strip) to ensure good sealing performance and prevent cold air leakage and the entry of outside hot air.

[0085] Some standards typically require that the opening force of a refrigerator door should not exceed 70N. This is especially true for drawers. Opening a drawer requires overcoming not only the resistance from negative pressure and door seal suction, but also the self-locking force of the guide rails and the weight of the load. Therefore, opening a refrigerator door is relatively difficult, affecting the convenience of use. For example, in French door and side-by-side refrigerators with larger freezer compartments, opening the freezer drawers is particularly strenuous.

[0086] In particular, as refrigerator storage space increases, the door size also increases, thus increasing the attractive force of the door seal and the negative pressure of the refrigerator. The weight of the drawers themselves, as well as the increased number of items stored inside the drawers, all contribute to making it more difficult to open the refrigerator door.

[0087] However, the negative pressure between the door and the cabinet, as well as the suction force of the door seal, are important factors in maintaining the airtightness of the storage space. Therefore, simply reducing the airtightness between the door and the cabinet cannot make opening the refrigerator door easier.

[0088] In related technologies, assisted handles are installed on the door to make opening the refrigerator door easier. Some assisted handles use transmission components to amplify the opening force acting on the door, but these transmission components are complex and have poor reliability.

[0089] In view of this, this application provides a refrigerator that utilizes the lever principle to install a handle assembly on the drawer, making it easier to open the drawer. Furthermore, the handle assembly forms a bearing surface, and after the handle assembly opens the drawer, it abuts against the drawer, allowing the user to pull the drawer outwards using the handle assembly. This enhances the contact surface between the handle assembly and the drawer, ensuring the structural strength of the handle assembly.

[0090] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0091] Combination Figure 1 Some embodiments of this application provide a refrigerator, which includes a cabinet 10, the cabinet 10 being configured to form a refrigeration compartment with a front opening for storing items.

[0092] Multiple refrigeration compartments can be provided to expand storage space. Depending on the storage temperature of the refrigeration compartments, they can include at least one cold storage compartment and at least one freezer compartment. The internal temperature of the cold storage compartment can be maintained between approximately 0°C and 5°C for storing items in refrigeration mode; the internal temperature of the freezer compartment can be maintained between approximately -30°C and 0°C for storing items in freezing mode.

[0093] In some possible implementations, at least one of the cooling chambers may also be configured as a vacuum chamber or a variable temperature chamber, etc., which will not be elaborated further in the embodiments of this application.

[0094] For example, there may be two refrigeration compartments, which may be stacked vertically or arranged side by side horizontally. One of them may be a refrigerator compartment and the other may be a freezer compartment.

[0095] In some embodiments, combined with Figure 1 The cabinet 10 may include a liner and a shell. The liner may be configured to form a refrigeration compartment with a front opening, which serves as an access port. The shell may be attached to the outside of the liner to form the appearance of the refrigerator.

[0096] The cabinet 10 may also include a cabinet insulation layer, which can be disposed between the cabinet liner and the cabinet shell. The cabinet insulation layer can insulate the cooling compartment to minimize heat exchange between the cooling compartment and the outside of the refrigerator, thus helping to ensure the cooling effect of the refrigerator.

[0097] The refrigerator in this embodiment may further include a refrigeration system for reducing the air temperature in the refrigeration compartment. Exemplarily, the refrigeration system may be housed within the cabinet 10. The refrigeration system may include a compressor, condenser, expansion valve, and evaporator connected in a cycle.

[0098] During refrigeration system operation, the compressor compresses refrigerant vapor, generating high-temperature, high-pressure refrigerant vapor, and delivers it to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then delivered to the expansion valve. The expansion valve reduces the pressure of the refrigerant liquid, transforming it from a high-pressure, low-temperature liquid into a low-pressure, low-temperature liquid, which is then delivered to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside the refrigerated room.

[0099] Continue to refer to Figure 1 The refrigerator in this embodiment may further include a refrigerator door 20, which is rotatably connected to the cabinet 10 to open or close the opening on the front side of the cabinet 10. Exemplarily, the refrigerator door 20 is hinged to the cabinet 10.

[0100] Each refrigeration compartment can be equipped with one refrigeration door 20; or, each refrigeration compartment can be equipped with two refrigeration doors 20, which can rotate in opposite directions to open or close the refrigeration compartment.

[0101] Of course, in some possible implementations, a drawer 100 is provided in the refrigeration compartment, for example, a drawer 100 is provided in a refrigeration compartment for freezing. The drawer 100 is installed in the refrigeration compartment in a pull-out manner. Exemplarily, the drawer 100 is provided with first guide rails on both sides along the width direction of the cabinet 10, and the refrigeration compartment is provided with second guide rails on both sides along the width direction of the cabinet 10. The first guide rails and the second guide rails extend along the depth direction of the cabinet 10, and the second guide rails cooperate with the first guide rails so that the drawer 100 can be pulled out relative to the refrigeration compartment.

[0102] The drawer 100 includes a drawer body that is slidably connected to the side of the refrigeration compartment; the drawer body is constructed to form an upward-opening storage cavity.

[0103] Combination Figure 2 The drawer 100 also includes a drawer door 110, which is fixed to the front side of the drawer body. When the drawer 100 is pushed into the refrigeration compartment, the drawer door 110 abuts against the front side of the cabinet 10 to ensure the sealing of the storage compartment.

[0104] The front of the drawer body can also have an opening, which can be closed using the drawer door 110.

[0105] Drawer door 110 may include an inner liner facing the storage cavity. Drawer door 110 may include a door panel, which is spaced out in front of the inner liner, and a door insulation layer is provided between the door panel and the inner liner to minimize heat exchange between the cooling compartment and the outside of the refrigerator, thus ensuring the refrigerator's cooling effect. The door insulation layer may be a foam layer, a vacuum insulation panel, etc.

[0106] The drawer door 110 may also include an upper cover 111, which is fixed to the top of the inner door liner and the door panel. The drawer door 110 may also include a lower cover, which is fixed to the bottom of the inner door liner and the door panel.

[0107] An operating part is constructed on at least one of the upper end cover 111 and the lower end cover, allowing the user's hand to push and pull the drawer 100 via the operating part. In this embodiment, the operating part is provided on the upper end cover 111 as an example for description.

[0108] In this embodiment, a handle assembly 200 is installed on the drawer door 110, allowing the user to push and pull the drawer 100 using the handle assembly 200.

[0109] In this embodiment of the application, the handle assembly 200 is illustrated by taking the upper cover 111 of the drawer door 110 as an example. However, this is not a limitation on the installation position of the handle assembly 200. For example, the handle assembly 200 can also be installed on the lower cover.

[0110] It should be noted that, in this embodiment, the handle assembly 200 is used as an example of being applied to the drawer door 110, but this is not a limitation on the application scenarios of the handle assembly 200. For example, in a refrigerator with a single-sided rotating door, the handle assembly 200 can also be provided on the opening side of the rotating door.

[0111] Combination Figure 3 The handle assembly 200 includes a pivot 220 and a handle 210. The handle 210 is rotatably mounted to the drawer door 110 via the pivot 220. The pivot 220 can be fixed to the handle 210, and the upper cover 111 of the drawer door 110 has a pivot hole in which the pivot 220 is rotatably mounted, allowing the handle 210 to rotate relative to the drawer door 110. Alternatively, the pivot 220 can be fixed to the upper cover 111 of the drawer door 110, and the handle 210 can form a pivot hole, with the pivot hole rotatably engaging with the pivot 220, allowing the handle 210 to rotate relative to the drawer door 110.

[0112] In some embodiments of this application, the handle 210 is elongated, which facilitates the creation of a larger operating space and makes it convenient for operation. The handle 210 has a top end 211 and a handle end that are opposite each other along its extension direction. The top end 211 is used to abut against the front side of the housing 10 and to rotate the handle 210 by means of the handle end.

[0113] It should be noted here that, in combination Figure 4 The abutment 211 of the handle 210 is the end of the handle 210 that abuts against the front side of the housing 10; while the handle end is the part where the user rotates the handle 210, and the handle 210 end has a certain length. For example, in Figure 4 In the subsequent length calculation, we will take the example where the end of handle 210 is located approximately in the middle of handle 210. According to the lever principle, the farther the user's grip on handle 210 is from the pivot 220, the less effort is required. However, considering user habits, the structural strength of handle 210, and the available space, the length of handle 210 is subject to certain limitations.

[0114] The pivot 220 is located between the abutment 211 and the handle, forming the fulcrum in the lever structure. The handle 210 acts as the lever, the abutment 211 as the resistance end, and the handle as the power end, creating a force-saving lever structure. The lever arm of the abutment 211 is shorter than that of the handle. According to the lever principle, the force exerted by the abutment 211 is greater than that exerted by the handle. Therefore, the user can turn the handle with less force, using the abutment 211 to push the drawer door 110 open relative to the front of the box 10, making it easier to open the drawer 100.

[0115] For example, the lever arm of the abutment 211 is L1, and when the handle end is approximately in the middle position of the handle 210, the lever arm of the handle end is L2. If the force applied to the abutment 211 is F1, the force applied to the handle end is F2. According to the lever principle, F1*L1=F2*L2, F1=F2*L2 / L1. Since L1 is less than L2, then L2 / L1>1, therefore F1>F2. That is, the user can obtain a larger opening force by applying a smaller force to the abutment 211, achieving the purpose of saving effort.

[0116] In some embodiments of this application, the handle assembly 200 is installed on the top side of the drawer door 110, such that the top abutment 211 can abut against the front side of the box body 10.

[0117] In other embodiments of this application, the handle assembly 200 is mounted on the top of the front side of the drawer door 110, and the drawer door 110 is configured to form an opening such that the abutment top 211 passes through the opening and abuts against the front side of the box body 10.

[0118] The cabinet 10 includes a central crossbeam 11 located between the chamber containing the drawer 100 and the refrigerator compartment above it, which can increase the structural strength of the cabinet 10. When the handle assembly 200 is located at the top of the drawer 100, the abutment 211 is configured to abut against the front side of the central crossbeam 11.

[0119] Combination Figure 5 In some embodiments of this application, the top structure of the drawer door 110 forms a front groove wall 112 and a rear groove wall 113. The front groove wall 112 and the rear groove wall 113 are opposite to each other and spaced apart along the thickness direction of the drawer door 110, and a pull-out groove is formed between the front groove wall 112 and the rear groove wall 113.

[0120] The upper cover 111 of the drawer door 110 is configured to form a front groove wall 112 and a rear groove wall 113, and the upper cover 111 of the drawer door 110 is also configured to form a groove bottom wall 114, which is connected to the bottom of the front groove wall 112 and the rear groove wall 113.

[0121] The top of the front groove wall 112 is lower than the top of the rear groove wall 113, so that the height of the front groove wall 112 is less than the height of the rear groove wall 113. This makes it convenient for the user to insert their hand into the pull-out groove to pull out the drawer 100, and also allows for a larger space on the rear side of the rear groove wall 113, which is convenient for installing a door seal.

[0122] Among them, combined Figure 6 The front groove wall 112 is provided with a notch 1121 to prevent the handle 210 from rotating, so that the handle end of the handle 210 can rotate outward through the notch 1121.

[0123] Combination Figure 7 and Figure 8 When drawer 100 is closed, the front surface of handle 210 does not protrude from the front surface of front groove wall 112, making the installation structure of handle 210 compact and having little impact on the appearance of the front side of drawer door 110. In particular, when drawer 100 is closed, the front surface of handle 210 can be flush with the front surface of front groove wall 112.

[0124] There is a gap between the part of the handle 210 and the rear groove wall 113 to accommodate the user's hand, so that the hand can apply force to the handle 210.

[0125] The handle 210 also has a top surface located at the top of its front surface. When the drawer 100 is closed, the top surface of the handle 210 does not protrude from the top surface of the front groove wall 112, thus facilitating the user to apply force to the handle 210 by stepping over it. For example, when the drawer 100 is closed, the top surface of the handle 210 is flush with the top surface of the front groove wall 112.

[0126] Continue to refer to Figure 6 The rear groove wall 113 is provided with a through-hole 1131 that extends through its thickness direction, and the top end 211 abuts against the front side of the box body 10 through the through-hole 1131.

[0127] Continue to refer to Figure 2 In some embodiments, the pivot 220 is along the height direction of the drawer door 110 (corresponding to...). Figure 2 Extending along the Z-axis. Thus, handle 210 extends in the horizontal plane (corresponding to...). Figure 2 The handle 210 rotates within the XY plane. When the handle end of the handle 210 rotates outward, the top end 211 rotates inward and abuts against the front side of the cabinet 10. With this configuration, the handle 210 does not change position in the height direction of the drawer door 110, which improves the convenience of user operation.

[0128] Furthermore, along the width direction of drawer door 110 (corresponding to...) Figure 2 In the X-axis direction, when the user faces the drawer door 110, the handle end is located on the right side of the top 211, which conforms to the user's operating habits and helps to improve the convenience of use.

[0129] The pivot 220 includes a first pivot portion 221 and a second pivot portion 222 coaxially arranged, with the first pivot portion 221 and the second pivot portion 222 spaced apart along the height direction of the drawer door 110. The handle 210 is provided with a first pivot hole 212 and a second pivot hole 213 coaxially arranged, with the first pivot hole 212 rotatably engaging with the first pivot portion 221 and the second pivot hole 213 rotatably engaging with the first pivot portion 221, thereby realizing the rotatable connection between the handle 210 and the pivot 220.

[0130] By setting the pivot 220 as a two-section shaft, a longer pivot 220 can be achieved, ensuring the stability of the rotational fit, while avoiding the impact on structural strength caused by a long pivot 220 section. Furthermore, the two-section pivot 220 structure distributes the rotational force of the handle 210 to two points, facilitating force dispersion and improving the structural strength and service life of the handle 210 installation.

[0131] In some possible implementations, a reinforcing member 115 is fixed inside the upper cover 111. The reinforcing member 115 extends along the width direction of the drawer door 110, thereby improving the structural strength of the upper cover 111. A first shaft portion 221 is disposed on the reinforcing member 115.

[0132] In some possible implementations, the handle assembly 200 also includes a fastener 230, which is fixed to the bottom side of the upper cover 111, and the fastener 230 is provided with a second shaft portion 222.

[0133] Continue to refer to Figure 2 In this embodiment of the application, the portion of the handle 210 between the pivot 220 and the handle end is configured to form a pressure-bearing surface 2151. The pressure-bearing surface 2151 is configured to abut against the front side of the drawer door 110 so that the drawer 100 can be pulled outward by the handle 210.

[0134] Among them, combined Figure 8 and Figure 9 The pressure-bearing surface 2151 is configured to abut against the front side of the rear groove wall 113. Figure 8 In the middle, the front surface of the handle 210 is flush with the front surface of the front groove wall 112, and the included angle between the bearing surface 2151 and the front side surface of the rear groove wall 113 is α; combined Figure 9 The handle 210 rotates outward through the notch 1121 of the front groove wall 112. When the bearing surface 2151 abuts against the front surface of the rear groove wall 113, the included angle between the front surface of the handle 210 and the front surface of the front groove wall 112 is α. Here, the included angle α is the rotation stroke of the handle 210.

[0135] When the pressure-bearing surface 2151 abuts against the front side of the drawer door 110, it can, on the one hand, limit the outward rotation angle of the handle 210, that is, limit the rotation stroke of the handle 210; on the other hand, after the drawer door 110 is opened by the top end 211, the abutment between the pressure-bearing surface 2151 and the front side of the drawer door 110, and the pull force of the drawer 100 applied by the handle 210, can be transmitted to the drawer door 110 through the pressure-bearing surface 2151, thereby driving the drawer 100 to be pulled outward. This can reduce the pull force of the drawer 100 acting on the pivot 220, so that the pivot 220 has a longer service life, and there is no need to set a thick pivot 220, making the structure of the handle assembly 200 compact.

[0136] Combination Figure 10 In some embodiments of this application, the handle 210 includes a handle portion 214, one end of which is configured as a handle end. The handle portion 214 is elongated and, combined with... Figure 8 When the drawer 100 is closed, the handle portion 214 extends along the width direction of the drawer door 110. The elongated handle portion 214 facilitates user operation and improves the user's grip flexibility.

[0137] Continue to refer to Figure 8 The handle 210 is located in the pull-out slot, and at this time the handle 210 is in the initial position. The front side of the handle portion 214 forms the front surface of the handle 210 and is flush with the front surface of the front slot wall 112. The top surface of the handle portion 214 forms the top surface of the handle 210 and is flush with the top surface of the front slot wall 112.

[0138] Continue to refer to Figure 10 The handle 210 may also include a pressure plate 215, which is connected to the other end of the handle portion 214. The pressure plate 215 is located on the rear side of the handle portion 214, and the rear surface of the pressure plate 215 forms a pressure-bearing surface 2151.

[0139] The pressure plate 215 is connected to the top surface of the handle portion 214. The pressure plate 215 has opposing front and rear surfaces, with the front surface facing the front groove wall 112 and the rear surface forming the pressure-bearing surface 2151. The front and rear surfaces of the pressure plate 215 are parallel, ensuring a consistent thickness across the plate surface. This results in a more stable structure for the pressure plate 215, preventing damage to certain areas due to inconsistent thickness. Furthermore, it simplifies the structure of the handle 210.

[0140] The handle 210 may also include a mounting part 216, which is located on the rear side of the pressure plate 215 and has a rear end structure opposite to the pressure plate 215 to form a top end 211; the mounting part 216 is rotatably connected to the drawer door 110 via a pivot 220.

[0141] In some embodiments, the mounting portion 216 has a rotatable roller 2164, the surface of which forms an abutment 211. Thus, when the roller surface abuts against the front side of the housing 10, the roller 2164 rolls relative to the front side of the housing 10 to reduce the friction between the abutment 211 and the front side of the housing 10, thereby reducing the possibility of friction marks forming on the front side of the housing 10.

[0142] In this embodiment, the mounting portion 216 is configured to form a shaft hole, which is rotatably connected to the rotating shaft 220. Of course, the mounting portion 216 can also be configured to form a rotating shaft 220, which is rotatably connected to the shaft hole provided on the drawer door 110.

[0143] In this embodiment, the handle 210 is designed with a handle portion 214 for easy user operation; a mounting portion 216 is provided for mounting the pivot 220; and a pressure plate 215 is provided to form a pressure-bearing surface 2151, which abuts against the front side of the drawer door 110. This allows the pulling force of the drawer 100 acting on the handle 210 to be transmitted to the drawer door 110 through the pressure-bearing surface 2151, reducing the pulling force acting on the pivot 220 and extending the service life of the handle assembly 200.

[0144] Combination Figure 10 and Figure 11 In some embodiments of this application, the mounting portion 216 may include an upper plate portion 2161, which is connected to one end of the pressure plate 215 away from the handle portion 214, wherein the upper plate portion 2161 is connected to the top end of the pressure plate 215. The end of the upper plate portion 2161 is configured to form an abutment 211.

[0145] The upper panel 2161 includes a panel body 2163 and a roller 2164. The panel body 2163 is connected to the end of the pressure plate 215 away from the handle portion 214. The roller 2164 is rotatably mounted on the panel body 2163, and the wheel surface of the roller 2164 forms an abutment 211. A hinge hole is provided on the panel body 2163, and a hinge shaft is fixed to the roller 2164. The hinge shaft is rotatably installed in the hinge hole, so that the roller 2164 is rotatably mounted on the panel body 2163. The axial direction of the hinge shaft is parallel to the axial direction of the rotating shaft 220, that is, the hinge shaft extends along the height direction of the drawer door 110.

[0146] The wheel surface of roller 2164 protrudes from the end face of plate body 2163, so that the wheel surface of roller 2164 can abut against the front side of box 10.

[0147] In this embodiment, by rotatably mounting a roller 2164 on the plate body 2163 of the upper plate 2161, the wheel surface of the roller 2164 abuts against the front side of the cabinet 10. This allows the roller 2164 to contact the front side of the cabinet 10 during the process of opening the drawer door 110, thereby reducing the friction between the top end 211 and the front side of the cabinet 10, thus avoiding the formation of marks on the front side of the cabinet 10 and helping to maintain the appearance of the refrigerator.

[0148] The mounting part 216 may also include a lower plate part 2162, which is connected to the handle part 214, and the lower plate part 2162 and the upper plate part 2161 are opposite to each other and spaced apart along the height direction of the drawer door 110.

[0149] Both the upper plate 2161 and the lower plate 2162 are rotatably connected to the drawer door 110 via a pivot 220. Specifically, the upper plate 2161 is rotatably connected to the drawer door 110 via a first pivot 221, and the lower plate 2162 is rotatably connected to the drawer door 110 via a second pivot 222.

[0150] Continue to refer to Figure 5 The drawer door 110 has two through-holes 1131 on its upper cover 111. The two through-holes 1131 are opposite each other along the height direction and are both located on the rear groove wall 113. The upper plate 2161 extends from the front side to the rear side of the rear groove wall 113 through the upper through-hole 1131; the lower plate 2162 extends from the front side to the rear side of the rear groove wall 113 through the lower through-hole 1131.

[0151] The upper plate 2161 has a first shaft hole 212, which is located in the plate body 2163 of the upper plate 2161. The lower plate 2162 has a second shaft hole 213, which is coaxially arranged with the first shaft hole 212. Figure 12 The first shaft portion 221 of the rotating shaft 220 is rotatably engaged with the first shaft hole 212, and the second shaft portion 222 of the rotating shaft 220 is rotatably engaged with the second shaft hole 213, thereby allowing the handle 210 to rotate relative to the drawer door 110.

[0152] In this embodiment, the mounting part 216 is provided with an upper plate part 2161 and a lower plate part 2162 arranged at intervals along the height direction of the drawer door 110. They are rotatably connected to the drawer door 110 via a pivot 220, so that the mounting part 216 and the pivot 220 have two rotatable connection positions. This helps to improve the reliability and stability of the connection between the handle 210 and the pivot 220, and ensures the rotation of the handle 210 relative to the drawer door 110.

[0153] Furthermore, in this embodiment of the application, the pivot 220 is provided with two shafts, such that the upper plate 2161 is rotatably connected to the drawer door 110 through the first shaft 221, and the lower plate 2162 is rotatably connected to the drawer door 110 through the second shaft 222. This ensures sufficient axial fit length and avoids setting an excessively long pivot 220, which would affect the structural strength.

[0154] Combination Figure 12 In some embodiments of this application, the reinforcing member 115 and the fixing member 230 are arranged at intervals along the height direction of the drawer door 110. The reinforcing member 115 is fixedly connected to the first shaft portion 221, and the fixing member 230 is fixedly connected to the second shaft portion 222.

[0155] The first shaft portion 221 and the first shaft hole 212 are located in the upper through-hole 1131, which can shield and protect the rotating connection part, prevent foreign objects from entering the mating part of the first shaft portion 221 and the first shaft hole 212, and improve the reliability of the rotating fit.

[0156] In some embodiments, the top end of the rear groove wall 113 bends backward and then downward, forming a downward-opening U-shaped groove structure at the top end of the upper cover 111, and the reinforcing member 115 is fixed in the U-shaped groove. A portion of the top wall portion 1132 of the U-shaped groove protrudes upward to form a boss portion 1133, and the boss portion 1133 and the top wall portion 1132 of the U-shaped groove are spaced apart along the height direction to form a through opening 1131. The top wall portion 1132 of the U-shaped groove is provided with a clearance hole so that the lower first shaft portion 221 can pass through and thus cooperate with the first shaft hole 212.

[0157] Thus, a U-shaped groove structure is formed at the top of the rear groove wall 113 to fix the reinforcing member 115; and the engagement of the first shaft portion 221 and the first shaft hole 212 is shielded and protected by the top wall portion 1132 and the boss portion 1133.

[0158] Reference Figure 13 and Figure 14 In some embodiments of this application, the fastener 230 is located on the rear side of the upper cover 111, and a portion of the fastener 230 extends below the upper cover 111. The fastener 230 can cover the through-hole 1131 on the lower side, facilitating the formation of a closed drawer door 110 chamber and the foaming of the insulation layer of the drawer door 110. Furthermore, the fastener 230 also provides a second shaft portion 222, which rotatably engages with the rotating hole of the lower cover plate.

[0159] The bottom surface of the groove bottom wall 114 of the upper end cover 111 is provided with a positioning post 1141, and the fixing member 230 is provided with a positioning hole 231. The positioning hole 231 cooperates with the positioning post 1141 to realize the positioning and installation of the fixing member 230 and the positioning hole 231.

[0160] The fastener 230 has buckles 232 on both sides along its width; the bottom surface of the groove bottom wall 114 has two ribs 1142, which are arranged along the width direction of the upper end cover 111 (corresponding to...). Figure 14 The ribs 1142 are arranged at intervals along the X-axis direction. Each rib 1142 is provided with a snap 1143. The fastener 230 is fixed to the upper end cover 111 by engaging with the snap 232 through the snap 1143. The positioning post 1141 is located between two ribs 1142. The two ribs 1142 also play a role in improving the structural strength of the upper end cover 111.

[0161] The fastener 230 forms a second shaft portion 222 at a position corresponding to the through-hole 1131, so that the lower plate portion 2162 passing through the through-hole 1131 is rotatably connected to the second shaft portion 222.

[0162] Reference Figure 15 In some embodiments of this application, the fastener 230 includes a mounting box 233 and a mounting plate 234. The mounting box 233 forms a snap-fit ​​232 and a first hole 2311. When the mounting box 233 is fixed to the upper cover 111, a contact surface is formed between the mounting box 233 and the upper cover 111 to improve the sealing of the connection between the mounting box 233 and the upper cover 111 and avoid the problem of foam overflow at the through-hole 1131. The mounting box 233 is generally L-shaped and can match the shape of the upper cover 111.

[0163] Reference Figure 12 and Figure 15 The mounting box 233 protrudes rearward to form a mounting groove 2331 with a front opening, providing space for the lower plate 2162. The mounting box 233 also forms a mating groove 2332, located on the opening side of the mounting groove 2331, and surrounding a portion of the mounting groove 2331. The mounting plate 234 is accommodated within the mating groove 2332, and the mounting plate 234 has a second hole 2312 at a position opposite to the first hole 2311, so that the positioning pin 1141 mates with the first hole 2311 and the second hole 2312 respectively, serving a positioning function. The first hole 2311 and the second hole 2312 form the positioning hole 231.

[0164] Mounting plate 234 also includes a rearwardly extending extension plate 2341, which extends into mounting groove 2331, and a second shaft portion 222 is provided on the extension plate 2341, as detailed in the following reference. Figure 12 .

[0165] The fastener 230 in this embodiment of the application has a simple structure and is easy to process and form by setting two parts: the mounting box 233 and the mounting plate 234.

[0166] Combination Figure 11 In some embodiments of this application, the handle portion 214 is configured to form a groove 2141, which extends along the extending direction of the handle portion 214. The opening of the groove 2141 faces downwards.

[0167] The handle assembly 200 also includes a pressure-bearing rod 240, one end of which is rotatably connected to the drawer door 110. Figure 5 and Figure 11 The drawer door 110 has a mounting hole 1144 on the bottom wall 114 of the groove of the upper cover 111. One end of the pressure rod 240 is provided with a second connecting shaft 242, which is rotatably connected to the mounting hole 1144, so that one end of the pressure rod 240 is rotatably connected relative to the drawer door 110.

[0168] The other end of the pressure rod 240 is provided with a first connecting shaft 241, which is inserted into the slide groove 2141.

[0169] When the handle 210 rotates relative to the rotating shaft 220, the first connecting shaft 241 slides along the slide groove 2141, thereby causing the pressure-bearing rod 240 to move with the handle 210, thus preventing the setting of the pressure-bearing rod 240 from affecting the rotation of the handle 210.

[0170] Furthermore, when the pressure-bearing surface 2151 abuts against the drawer door 110, the handle 210 also drives the drawer 100 to be pulled outward via the pressure-bearing rod 240. The slide 2141 has a first end and a second end, with the first end located near the handle portion 214 relative to the second end. When the handle 210 is housed in the pull-out groove of the upper cover 111, the first connecting shaft 241 abuts against the first end of the slide 2141; when the handle 210 rotates relative to the pivot 220 and the pressure-bearing surface 2151 abuts against the drawer door 110, the first connecting shaft 241 slides along the slide 2141 to the second end and abuts against it. Thus, the pulling force applied by the user to the handle 210 can be transmitted to the drawer door 110 via the pressure-bearing rod 240, thereby causing the drawer 100 to move outward as a whole.

[0171] The handle assembly 200 of this application embodiment features a pressure-bearing rod 240, one end of which is rotatably connected to the drawer door 110, and the other end is provided with a first connecting shaft 241, inserted into a slide groove 2141. This allows the pressure-bearing rod 240 to move with the handle 210, preventing the pressure-bearing rod 240 from affecting the rotation of the handle 210. When the pressure-bearing surface 2151 abuts against the drawer door 110, the pulling force applied by the user to the handle 210 can be transmitted to the drawer door 110 through the pressure-bearing rod 240, thereby causing the drawer 100 to move outward as a whole.

[0172] Therefore, the pulling force applied by the user to the handle 210 can be transmitted to the drawer door 110 through the pressure-bearing rod 240 and the pressure-bearing surface 2151, thus dispersing the pulling force on the handle 210 and avoiding concentrated force that could easily damage it. The pressure-bearing rod 240 and the pressure-bearing surface 2151 are located at opposite ends of the handle portion 214 along its length, which better disperses the pulling force, making it easier to open the drawer 100.

[0173] In some embodiments of this application, when closing drawer 100, the handle 210 can be reset by rotating it in the opposite direction. In this embodiment, viewed from above, rotating the handle assembly 200 clockwise causes the abutment 211 to abut against the front side of the housing 10, thereby opening the drawer door 110. Therefore, when closing drawer 100, rotating the handle 210 counterclockwise allows it to be received within the drawer slot, enabling the drawer 100 to close smoothly and preventing the abutment 211 from protruding and affecting the closing of the drawer 100.

[0174] In other embodiments of this application, the handle assembly 200 is provided with a resetting elastic element. When the handle 210 is rotated clockwise to open the drawer door 110, the elastic element deforms elastically; when the user releases the handle 210, the elastic element returns to its original deformation, causing the handle 210 to rotate counterclockwise, thereby resetting the handle 210.

[0175] Reference Figure 16 The handle 210 is constructed with a mounting cavity 217, within which a mounting shaft 2171 is disposed. The mounting cavity 217 can be located below the pressure plate 215 to prevent it from interfering with the contact between the pressure surface 2151 and the drawer door 110. The mounting shaft 2171 can extend along the height of the drawer door 110, facilitating the installation of the torsion spring 250, which will be described later.

[0176] The handle 210 is also configured to form an opening 2172, which is connected to the mounting cavity 217, providing an opening for part of the torsion spring 250 to pass through the mounting cavity 217.

[0177] The handle assembly 200 of this embodiment further includes a torsion spring 250, which includes a spring body and two torsion arms, which are respectively connected to the two ends of the spring body in the axial direction. The spring body of the torsion spring 250 is sleeved on the mounting shaft 2171, and one of the torsion arms of the torsion spring 250 abuts against the cavity wall of the mounting cavity 217, thereby fixing the torsion spring 250.

[0178] Combination Figure 11The other torsion arm of the torsion spring 250 extends through the through-hole 2172 to the outside of the mounting cavity 217 and abuts against the drawer door 110. The mounting cavity 217 is located on the front side of the rear groove wall 113, and the other torsion arm of the torsion spring 250 extends through the through-hole 2172 to the outside of the mounting cavity 217 and abuts against the front side of the rear groove wall 113.

[0179] The torsion spring 250 is configured to elastically deform when the handle 210 opens the drawer 100, generating a torsional torque between the two torsion arms. When the user releases the handle 210, the torsion spring 250 returns to its original deformation, and the torsional torque causes the handle 210 to rotate toward the rear groove wall 113, so that the handle 210 returns to its initial position, preventing the handle 210 from extending outside the drawer groove.

[0180] Therefore, in this embodiment of the application, the handle assembly 200 has a torsion spring 250 installed in the mounting cavity 217 of the handle 210. The two torsion arms of the torsion spring 250 abut against the cavity wall of the mounting cavity 217 and the drawer door 110, respectively. Furthermore, the torsion spring 250 elastically deforms when the handle 210 opens the drawer 100. Thus, after the handle 210 loses the user's operating force, the torsion spring 250 drives the handle 210 to rotate in the opposite direction, so that the handle 210 automatically returns to the closed state of the drawer 100 without any additional operation.

[0181] Combination Figure 11 A protrusion 2191 is provided on the inner side of the handle 210, and the protrusion 2191 is located at the end of the handle 210 opposite to the pivot 220. By providing the protrusion 2191, the possibility of the user's hand slipping off the end of the handle 210 can be reduced, thereby improving the reliability of user operation.

[0182] Continue to refer to Figure 16 In some possible implementations of this application, the handle 210 includes an outer shell 218 and an inner liner 219. The outer shell 218 is configured to form a top abutment 211 and a pressure-bearing surface 2151. The outer shell 218 is rotatably connected to the drawer door 110 via a pivot 220.

[0183] The outer casing 218 may include a front side panel that forms the front side of the handle portion 214. The outer casing 218 also includes an upward flange, with the top end of the front side panel bent backward to form an upward flange; the outer casing 218 also includes a downward flange, with the bottom end of the front side panel bent backward to form a downward flange. One end of the downward flange has an opening for a groove 2141, which, together with the inner liner 219, forms the groove 2141; the other end of the downward flange extends backward to form a lower plate portion 2162. The end of the upward flange facing away from the groove 2141 is connected to a pressure plate 215. The top end of the pressure plate 215 bends backward to form an upper plate portion 2161.

[0184] The inner liner 219 is fixed to the rear side of the outer shell 218, and the inner liner 219 forms a handle end, and the end of the inner liner 219 forms a protrusion 2191 that protrudes away from the outer shell 218.

[0185] The inner liner 219 and the outer shell 218 can be connected by a snap-fit, a simple and reliable method. The end of the inner liner 219 opposite to the protrusion 2191 forms an upward-opening groove 2192, within which the mounting shaft 2171 is positioned. After the inner liner 219 and the outer shell 218 are fixedly connected, the groove 2192 and the upper flange of the connection portion with the pressure plate 215 form a mounting cavity 217.

[0186] In this embodiment, the inner liner 219 is a plastic liner, which provides a good feel for the user's hand and avoids burrs and other structural defects found in the metal outer shell. The outer shell 218 is a metal outer shell, which provides sufficient structural strength for the handle 210.

[0187] The following is combined with Figure 4 This describes exemplary settings of various parameters in some possible embodiments of this application.

[0188] The lever arm of the top end 211 is L1, and when the handle end is approximately in the middle position of the handle 210, the lever arm of the handle end is L2. If the force applied to the top end 211 is F1, the force applied to the handle end is F2.

[0189] Along the direction of drawer 100's pull-out, the distance by which drawer door 110 is pushed open is d. The center of pivot 220 is O, the center of roller 2164 is O1 when closed, and the center of roller 2164 is O2 when drawer door 110 is pushed open. The distance along the direction of drawer 100's pull-out (corresponding to...) Figure 4 (In the Y-axis direction), the distance between O1 and O2 is d. When the bearing surface 2151 abuts against the front side of the drawer 100, the rotation angle of the handle 210 is α. The angle between the line connecting O and O1 and the horizontal direction is β. Along the horizontal direction (corresponding to...) Figure 4 (in the X-axis direction), the distance a1 between O and O1, and the distance b between O and the handle end; along the pull-out direction of drawer 100 (corresponding to...) Figure 4 (Y-axis direction in the diagram), the distance a2 between O and O1.

[0190] When drawer door 110 is closed, due to the pressure difference between the inside and outside and the suction force of the door seal, the opening force needs to reach 60N, i.e., F1 = 60N. Assuming L2 / L1 ≥ 2, then F2 = 30N. When drawer door 110 is opened by about 5mm, it can be ensured that at least part of drawer door 110 is detached from the front side of the box body 10, balancing the pressure difference between the inside and outside and eliminating the suction force between the door seal and the box body 10. Assuming d = 6mm.

[0191] After drawer door 110 is pushed open, the user continues to open the door using handle 210. Therefore, the smaller the rotation angle α of handle 210, the better the user experience. Generally, α ≤ 15°.

[0192] The average adult's palm width is around 100mm, and the grip length at the handle end, that is, the length of the user's grip on the handle part 214, is 120mm. The longer the grip length, the less effort is required; however, the higher the requirements for the rigidity and structural strength of the handle 210, the higher the cost will be.

[0193] Assuming a² = 13 mm, α = 15°, β ∈ (0°, 90°), then:

[0194] a1*tanβ=a2 ①

[0195] L1*sinβ=a2 ②

[0196] L1*sin(α+β)=L1 ③

[0197] According to formulas ① to ③ above, a1, β, and L1 have unique solutions within their respective ranges. Using the constraints satisfied by the dashed and dotted triangles, we can measure a1≈24.9mm, and take a1=25mm.

[0198] Since L2 / L1≥2, then b / a2≥2, therefore b≥50mm.

[0199] To meet the 120mm grip length requirement, assuming b = 50mm, the angle θ between the inner side of the handle portion 214 and the side of the upper flange is acute. This location is a stress concentration point for the handle 210, and an acute angle is detrimental to stress dispersion, posing a risk of tearing. To disperse stress, θ is an obtuse angle. Therefore, b should be at least 65mm. Assuming b = 70mm, then a1 ≤ 35mm. The smaller a1 is, the larger the rotation angle α of the handle 210, so a1 = 35mm and b = 70mm can be chosen.

[0200] It is understood that the above parameters are only illustrative and do not constitute a limitation on the range of parameters of the handle 210 in the embodiments of this application.
