Abstract
Description
Technical Field
[0001] The embodiments of the present invention relate to the technical field of household appliances, and in particular to a household appliance. Background Art
[0002] With the current market and customer needs, the user experience requirements for household appliances are constantly improving. For example, when the door of a household appliance is heavy, the user needs to apply a large force to the door handle to open the door, which is a very poor user experience. For household appliances with heat preservation requirements such as refrigerators, the box is usually in a negative pressure state when the door is closed. Some refrigerators also have magnetic strips in the door seal to further enhance the sealing. These factors will increase the force that the user needs to apply to the door handle when opening the door, further affecting the user experience. Summary of the invention
[0003] An object of embodiments of the present invention is to provide an improved household appliance.
[0004] Therefore, an embodiment of the present invention provides a household appliance, comprising a box body and a door, wherein the box body defines at least one storage chamber, and the door is movably connected to the front of the box body to open or close at least a part of the storage chamber, and the door comprises: a door body; a handle assembly, comprising: a handle seat fixed to the door body, the handle seat comprising a hinge shaft; a handle body hinged to the handle seat, the handle body comprising a sleeve portion sleeved on the hinge shaft; an ejection mechanism, comprising a first rod portion extending along the thickness direction of the door, and a second rod portion extending from the first rod portion toward the handle body; wherein the handle body can be rotated around the hinge shaft from a first position to a second position, during which time the sleeve portion rotates around the hinge shaft to push the second rod portion to move toward the box body, thereby causing the first rod portion to abut against the box body.
[0005] Compared with the existing door handle design on household appliances that cannot provide mechanical assistance to users, which makes it very laborious for users to open the door, the external handle structure design provided in this embodiment can provide mechanical assistance to users to open the door, making it easier for users to operate the door handle and optimizing the user experience. Specifically, the lever principle is used, and the lever fulcrum is located at the hinge axis, so as to maximize the length of the force arm on the handle body side, minimize the force required by the user to operate the handle body, and realize a more labor-saving lever structure.
[0006] Furthermore, the door opening system formed by the handle assembly is a rotating lever structure, and the door is pushed out of the box body during the rotation of the handle body, thereby achieving a labor-saving effect. Specifically, the direction of the force is transformed at the lever fulcrum. When the user opens the door, the handle body is lifted up and forward. With the cooperation of the sleeve part and the second rod part, the direction of the force of the handle body rotating around the hinge axis under the user's operation is transformed at the lever fulcrum into the direction of the force of the first rod part moving forward and backward. As a result, the force applied by the user is transmitted to the box body with almost no loss, so that the user can open the door with more labor saving in a more ergonomic operation mode.
[0007] Optionally, the sleeve portion includes an opening portion opened toward the ejection mechanism, and the end of the second rod portion extends into the opening portion. Thus, the sleeve portion rotating with the rotation of the handle body can reliably contact the second rod portion, thereby pushing the second rod portion to move synchronously.
[0008] Optionally, the household appliance further comprises: a retaining wall extending outward from the front edge of the opening, and the angle between the retaining wall and the sleeve portion at the edge is associated with the rotation angle of the handle body from the first position to the second position. Thus, the maximum rotation angle of the handle body can be reasonably designed as needed, so that the movement amplitude of the user's hand can be controlled within a reasonable range, further optimizing the user experience.
[0009] Optionally, the sleeve portion further comprises: a pair of limiting portions, which are arranged on both sides of the opening portion along the axial direction of the hinge shaft to limit the relative position of the second rod portion and the opening portion in the axial direction of the hinge shaft, thereby avoiding unexpected misalignment of the second rod portion and the sleeve portion during movement, and ensuring reliable transmission of power to the second rod portion.
[0010] Optionally, the handle body includes: a gripping portion; and a connecting arm for connecting the gripping portion and the sleeve portion. Thus, the gripping portion is convenient for the user to grip and apply force, the connecting arm serves as a power arm, the second rod portion serves as a resistance arm, and the sleeve portion and the axis of the hinge shaft coincide as a lever fulcrum, and the three cooperate to form a lever structure, transmitting the door opening force applied by the user to the box body to realize the door opening action.
[0011] Optionally, the length of the connecting arm is greater than the length of the second rod portion. With this embodiment, the force point is on the second rod portion, so the resistance arm is equivalent to the length of the second rod portion, and the force application point is on the handle body, so the power arm is equivalent to the length of the connecting arm. As a result, the power arm is longer than the resistance arm, so that the handle assembly can form a labor-saving lever, and the user can open the door by applying a small force.
[0012] Optionally, the sleeve portion further includes: a stopper, which is arranged near the hinge shaft, and the stopper is used to stop the handle body at the first position. Thus, the stopper plays a limiting role, limiting the maximum rotation angle of the handle body. For example, it is ensured that the rotation angle of the handle body is basically limited to between 0° and 90°. Furthermore, when the handle body is reset to the first position, the stopper prevents the handle body from excessive movement and collision with other parts of the door body, thereby preventing the handle body from being damaged. This is conducive to extending the service life of the parts.
[0013] Optionally, the sleeve portion is located between the stopper portion and the hinge shaft, so that the stopper portion and the sleeve portion can function independently without interfering with each other.
[0014] Optionally, along the direction in which the handle body rotates toward the first position, the blocking portion is located in front of the handle body. Furthermore, the blocking portion is located in front of the connecting arm. After the user pulls the handle body to, for example, the second position and lets go, as the force applied to the handle body disappears, the handle body automatically resets to the first position under the action of gravity. When the handle body falls back to the first position, the connecting arm is blocked by the blocking portion located in the front, and the trend of the handle body continuing to rotate forward is stopped, thereby achieving automatic stopping of the handle body in the first position. Thus, the handle body can be automatically reset to the first position without the need for additional user operation, thereby simplifying the user's operating steps and further optimizing the user experience. Furthermore, when the handle body is in the first position, the connecting arm is located in front of the blocking portion in the thickness direction of the door and covers the blocking portion, making the front of the door more beautiful.
[0015] Optionally, the blocking portion includes a baffle plate extending from a position close to the hinge axis toward a direction away from the hinge axis, and when the handle body is in the first position, the handle body and the baffle plate are in surface contact. Further, the connecting arm and the baffle plate are in surface contact. Thus, the baffle plate can not only play a role of stopping, but also serve as a reinforcement to strengthen the structural strength of the connecting arm.
[0016] Optionally, a first avoidance portion is provided on a side of the hinge shaft facing the ejection mechanism, and the sleeve portion and the first avoidance portion together enclose a space for the second rod portion to move along the thickness direction of the door. Thus, the hinge shaft is designed with an adaptive structure to ensure that the second rod portion can move forward and backward smoothly, thereby transmitting the output force of the lever structure to the first rod portion as loss-free as possible.
[0017] Optionally, the sleeve portion is provided with a second avoidance portion connected to the opening portion, for avoiding the second rod portion moving toward the box body under the push of the sleeve portion. Thus, the sleeve portion is adaptively designed to give way to the second rod portion, and reserve sufficient movement space for the second rod portion to move backwards under the push of the rotating sleeve portion.
[0018] Optionally, the handle base includes: a guide mechanism, which is arranged on the side of the door and extends along the thickness direction of the door, and the guide mechanism is used to guide the movement direction of the first rod portion. Thus, the first rod portion is ensured to move along the front-back direction, and the force applied by the user is transmitted to the box body as loss-free as possible to push the door open.
[0019] Optionally, the household appliance further comprises: a reset mechanism, which is used to push the ejection mechanism in a direction away from the box body so that the handle body returns to the first position. Thus, when the user pulls the handle body to, for example, the second position and then lets go, as the force applied to the handle body disappears, the handle movement system automatically and quickly returns to the first position under the dual effects of gravity and the reset mechanism.
[0020] Optionally, the direction of the force generated by the reset mechanism is parallel to the thickness direction of the door. Thus, it can play a guiding and force balancing role. Specifically, the movement direction of the ejection mechanism under the action of the sleeve portion during the rotation of the handle body from the first position to the second position is parallel to but opposite to the movement direction of the ejection mechanism under the action of the reset mechanism during the rotation of the handle body from the second position back to the first position, which is conducive to the handle body quickly switching between the first position and the second position.
[0021] Optionally, the reset mechanism includes an elastic member, and the two ends of the elastic member along the elastic force direction are respectively connected to the handle seat and the second rod portion. Thus, the handle body is indirectly driven to return to the first position through the elastic member to assist in resetting the handle motion system.
[0022] Optionally, the door body has a groove open toward one side surface and the front surface of the door body, the handle assembly is installed in the groove, and the door further includes a cover plate for covering at least the ejection mechanism from the side surface. Thus, the groove is provided in the door body to accommodate the handle assembly so as to hide the door handle to a certain extent, so that the appearance of the door body provided with the handle assembly of this embodiment can still remain relatively flat, which is conducive to improving the appearance of the door.
[0023] Optionally, the cover plate is provided with a notch, and the notch exposes the portion of the handle body except the sleeve portion from the side, thereby improving the user's operating convenience and preventing the cover plate from hindering the user's operation on the handle body.
[0024] Optionally, the door body includes a front panel, a rear wall, and a frame arranged along the periphery of the door body, the front panel, the rear wall, and the frame together define a heat-insulating space, the heat-insulating space is filled with a heat-insulating material to form a heat-insulating layer, and the groove is formed in one of the frames. Therefore, for household appliances such as refrigeration appliances that require a high door-opening force, the more labor-saving handle assembly described in this embodiment has a particularly significant effect on improving the user experience.

DETAILED DESCRIPTION
[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, a specific embodiment of the present invention is described in detail below with reference to the accompanying drawings.
[0033] Figure 1 is a schematic diagram of a household appliance 1 according to an embodiment of the present invention, Figure 2 yes Figure 1 A partial enlarged view of area A in the middle.
[0034] The household appliance 1 may have a storage space defined by a box body 10, and the storage space may be opened or closed by a door 11 movably connected to the box body 10. The household appliance 1 may be a refrigeration appliance, a cabinet, etc., and the refrigeration appliance may be a refrigerator, a freezer, a wine cabinet, etc.
[0035] Next, the present embodiment is described in detail by taking the household appliance 1 as a refrigeration appliance as an example. The refrigeration appliance may be, for example, a single-door refrigerator, a double-door refrigerator, a multi-door refrigerator, a side-by-side refrigerator, etc. The door 11 described in the present embodiment may be applied to any door of the aforementioned various refrigerators. Figure 1 A double-door refrigerator is used as an example for exemplary display. In order to more clearly display the storage room 101, Figure 1 The upper door 11 is not shown.
[0036] For ease of description, in this embodiment, the width direction of the household appliance 1 is recorded as the x direction, the depth direction is recorded as the y direction, and the height direction is recorded as the z direction. In this embodiment, the front-to-back direction refers to the y direction and the opposite direction thereof, wherein the front or the front side refers to the direction facing the user when the household appliance 1 is in use, and the rear or the rear side refers to the direction away from the user when the household appliance 1 is in use.
[0037] Specifically, the household appliance 1 of this embodiment may include a housing 10 and a door 11. The housing 10 defines at least one storage chamber 101, and the door 11 is movably connected to the front of the housing 10 to open or close at least a portion of the storage chamber 101. For example, the storage chamber 101 may include a freezer, a refrigerator, or a temperature-changing chamber.
[0038] Furthermore, the door 11 may include an insulating space 111 filled with insulating material. When the door 11 closes the storage chamber 101, the insulating layer formed by the insulating space 111 has the effect of isolating heat to ensure that the storage chamber 101 has a better refrigeration / freezing effect.
[0039] Further, the door 11 may include a door body 110, and a handle assembly 2 disposed on the door body 110. The handle assembly 2 is suitable for forming a door opening system, and a user may open or close the door 11 by operating the handle assembly 2.
[0040] For example, the door body 110 may include a front panel 112, a rear wall facing the box body 10 when the door 11 is closed, and a door frame 113 arranged along the periphery of the door body 110. The door frame 113 is suitable for closing the side of the door body 110, and the front panel 112, the rear wall and the door frame 113 jointly define the heat-insulating space 111. In some embodiments, the front panel 112 forms at least a portion of the front boundary of the heat-insulating space 111 so that the heat-insulating material contacts the rear side of the front panel 112. In other embodiments, another layer of door panel may be further provided on the rear side of the front panel 112. The front panel 112 may be a glass plate or a ceramic plate.
[0041] The door frame 113 may include an upper side card and a lower side card located on opposite sides of the door body 110 along the z direction, and a left side card and a right side card located on opposite sides of the door body 110 along the x direction. The upper side card may also be referred to as a door end cover. In some embodiments, the door frame 113 may be an independent component and assembled to the upper side of the door body 110 during assembly.
[0042] Further, the handle assembly 2 may include a handle seat 21, such as Figure 3 The handle seat 21 may include a rear cover 21a facing the box body 10 when the door 11 is closed, and a pair of side walls 21b opposite to each other along the x direction, the rear cover 21a and the pair of side walls 21b jointly define a receiving space 211 open to the front and upward, and the receiving space 211 is suitable for receiving other components of the handle assembly 2.
[0043] Furthermore, the handle base 21 can be fixed to the door body 110. For example, a pair of side walls 21b can be provided with ribs 212 on the opposite sides, and the door body 110 can be provided with buckles (not shown) accordingly. During assembly, the ribs 212 are embedded in the corresponding buckles to fix the handle base 21 to the door body 110.
[0044] Further, the handle seat 21 may include a hinge shaft 213. For example, the hinge shaft 213 may be disposed on at least one of the pair of side walls 21b and extend toward the other of the pair of side walls 21b. In the example where the handle assembly 2 is disposed on the upper side card, the axial direction of the hinge shaft 213 may be parallel to the x direction.
[0045] Further, combined with Figures 1 to 5 The handle assembly 2 may further include a handle body 22, which is hinged to the handle seat 21. Specifically, the handle body 22 may include a sleeve portion 221 sleeved on the hinge shaft 213. The sleeve portion 221 may be cylindrical and sleeved on the hinge shaft 213, and the sleeve portion 221 may rotate around the hinge shaft 213 to drive the entire handle body 22 to rotate around the axis of the hinge shaft 213, such as Figure 1 , Figure 2 , Figure 7 and Figure 8Further, the axis of the sleeve portion 221 coincides with the axis of the hinge shaft 213 .
[0046] Further reference Figure 1 , Figure 2 and Figure 6 The handle assembly 2 may further include an ejection mechanism 23, which may specifically include a first rod portion 231 extending along the thickness direction (e.g., y direction) of the door 11, and a second rod portion 232 extending from the first rod portion 231 toward the handle body 22. For example, the second rod portion 232 may be perpendicular to the first rod portion 231, that is, the second rod portion 232 may extend along the z direction. In some embodiments, the connection between the second rod portion 232 and the first rod portion 231 may be an arc transition.
[0047] Further, the handle body 22 can be rotated around the hinge axis 213 from a first position (such as Figure 1 and Figure 7 ) to the second position (as shown) Figure 8 ). Among them, Figure 2 The schematic diagram exemplarily shows that the handle body 22 is rotated to an intermediate position between the first position and the second position.
[0048] For example, in a plane perpendicular to the x-direction, the handle body 22 can be Figure 7 and Figure 8 The viewing angle is shown rotating clockwise from the first position to the second position.
[0049] Furthermore, when the handle body 22 rotates from the first position to the second position, the sleeve portion 221 rotates around the hinge shaft 213 to push the second rod portion 232 to move toward the box body 10 , thereby causing the first rod portion 231 to abut against the box body 10 .
[0050] For example, the handle body 22, the hinge shaft 213 and the ejection mechanism 23 may constitute a lever structure, and the hinge shaft 213 forms a lever fulcrum under the cooperation of the sleeve portion 221, converting the rotational motion of the handle body 22 into the linear motion of the ejection mechanism 23. As the handle body 22 rotates to the second position, the first rod portion 231 moves backward to resist the box body 10. Further, under the resisting force of the first rod portion 231, the door 11 is ejected, and the user continues to pull the handle body 22 forward to further open the door 11 to expose more of the storage chamber 101.
[0051] In some embodiments, the handle body 22 is located as follows Figure 1 and Figure 7In the first position shown, the end of the first rod portion 231 away from the second rod portion 232 (i.e., the end 231a of the first rod portion 231 facing the box body 10) can be adjacent to the box body 10. In this example, adjacent can mean that the two are in contact or have a non-zero gap, as long as the sealing performance of the door 11 to the box body 10 is not affected.
[0052] In some embodiments, after the handle body 22 leaves the first position, it reaches a position such as Figure 8 Before the second position shown, the end of the first rod portion 231 moving backward abuts against the box body 10. In other words, the door 11 is pushed out while the handle body 22 rotates toward the second position. Thus, before the handle body 22 reaches the second position, the door 11 has been pushed out a certain distance, and the user can save more effort when continuing to pull the handle body 22 in the second position to further open the door 11.
[0053] In the example where the household appliance 1 is a refrigeration appliance, the door 11 is pushed out to a degree that is at least sufficient to overcome the negative pressure in the storage chamber 101 and / or the magnetic attraction between the door seal and the box body 10 before the handle body 22 reaches the second position. For example, when the handle body 22 is in the second position, the door 11 is pushed out to a state where the storage chamber 101 is in communication with the outside.
[0054] In this example, the handle assembly 2 is directly exposed on the outer surface of the door 11 , so the handle assembly 2 can also be understood as an external handle.
[0055] Therefore, the external handle structure design provided in this embodiment can provide mechanical assistance for the user to open the door 11, making it easier for the user to operate the door handle and optimizing the user experience. Specifically, the lever principle is used, and the lever fulcrum is located at the hinge shaft 213, so as to maximize the length of the force arm on the handle body 22 side, minimize the force required by the user to operate the handle body 22, and realize a more labor-saving lever structure.
[0056] Furthermore, the door opening system formed by the handle assembly 2 is a rotating lever structure, and the door 11 is pushed out of the box body 10 during the rotation of the handle body 22, thereby achieving a labor-saving effect. Specifically, the direction of the force is transformed at the lever fulcrum. When the user opens the door 11, the handle body 22 is lifted upward and forward. With the cooperation of the sleeve portion 221 and the second rod portion 232, the direction of the force of the handle body 22 rotating around the hinge shaft 213 under the user's operation is transformed at the lever fulcrum into the direction of the force of the first rod portion 231 moving forward and backward. As a result, the force applied by the user is transmitted to the box body 10 with almost no loss, so that the user can open the door 11 with more labor-saving operation in a more ergonomic manner.
[0057] Furthermore, for household appliances 1 such as refrigeration appliances that require a relatively high door-opening force, the more labor-saving handle assembly 2 described in this embodiment has a particularly significant effect on improving the user experience.
[0058] In a specific implementation, continue to refer to Figure 2 , Figure 7 and Figure 8 The door body 110 may have a groove 114 open toward one side and the front surface of the door body 110 , and the groove 114 may be formed in one of the door frames 113 . Figure 1 and Figure 2 The example in which the groove 114 is open toward the upper side surface and the front surface is taken as an example for exemplary display. In other words, the groove 114 can be formed on the upper side card and open upward and forward.
[0059] In actual application, a groove 114 open to the left, right or bottom side can also be formed on the left side, right side or bottom side of the door 11, and accordingly, the handle assembly 2 is arranged on the left side, right side or bottom side of the door 11.
[0060] Furthermore, the groove wall of the groove 114 may be combined with a heat insulating material.
[0061] Further, the handle assembly 2 can be installed in the groove 114. Thus, the groove 114 is provided in the door body 110 to accommodate the handle assembly 2 to hide the door handle to a certain extent, so that the appearance of the door body 110 provided with the handle assembly 2 of this embodiment can still remain relatively flat, which is conducive to improving the appearance of the door 11.
[0062] In some embodiments, the rear cover 21a and the pair of side walls 21b together form the rear boundary and the left and right boundaries of the groove 114. That is, the groove wall of the groove 114 can reuse the rear cover 21a and the pair of side walls 21b.
[0063] In some embodiments, another layer of partition may be provided on the rear side of the rear cover 21a and / or the outer side of the pair of side walls 21b, and the partition is suitable for forming the groove wall of the groove 114. Further, a buckle for cooperating with the rib 212 may be provided on the partition. In this example, the handle assembly 2 is detachable for easy maintenance and replacement.
[0064] In a variation, the groove 114 may be eliminated, and the handle assembly 2 may be directly mounted on the front panel 112. In this example, the handle assembly 2 may protrude forward from the front surface of the door body 110.
[0065] In a specific implementation, continue to refer to Figure 5 , Figure 7 and Figure 8The sleeve portion 221 may include: an opening portion 222 opened toward the ejection mechanism 23 , and the end 232 a of the second rod portion 232 extends into the opening portion 222 .
[0066] Specifically, the opening portion 222 may extend along the axial direction (eg, x-direction) of the hinge shaft 231 .
[0067] Furthermore, the end 232 a of the second rod portion 232 may refer to an end of the second rod portion 232 away from the first rod portion 231 , that is, an end portion close to the handle body 22 .
[0068] For example, the ejection mechanism 23 may be located above the handle body 22 and the hinge shaft 213. Accordingly, the opening 222 is open upward, and the second rod 232 extends downward so that the end 232a extends into the opening 222.
[0069] Furthermore, when the handle body 22 rotates throughout the entire range between the first position and the second position, the end 232a of the second rod portion 232 remains in the state of extending into the opening 222. Figure 7 and Figure 8 From the perspective of FIG. 2 , the opening portion 222 rotates clockwise synchronously with the handle body 22, thereby pushing the end 232a of the second rod portion 232 extending thereinto backward.
[0070] Therefore, the sleeve portion 221 that rotates as the handle body 22 rotates can reliably contact the second rod portion 232, thereby pushing the second rod portion 232 to move synchronously.
[0071] In some embodiments, the opening portion 222 and the portion of the handle body 22 other than the sleeve portion 221 (for example, Figure 4 The gripping portion 225 shown in the figure may be located on both sides of the axis of the hinge shaft 213 in the z direction and may be located in front of the axis in the y direction. Further, as the handle body 22 rotates, the extent to which the end 232a of the second rod portion 232 extends into the opening 222 may change.
[0072] As the handle body 22 rotates clockwise, the grip portion 223 rotates forward and upward, and the opening portion 222 rotates backward and upward synchronously. The upwardly moving opening portion 222 causes the end 232a of the second rod portion 232 to extend into the opening portion 222 to a greater extent. At the same time, the backwardly moving opening portion 222 pushes the end 232a of the second rod portion 232 to move backward.
[0073] In some embodiments, when the handle body 22 is in the first position, the end 232a of the second rod portion 232 may contact the front edge 222a of the opening portion 222. Thus, when the handle body 22 starts to rotate from the first position, the ejection mechanism 23 is pushed to move backward, which is conducive to making the most of the lever structure to achieve a more labor-saving door opening process.
[0074] In some embodiments, the opening portion 222 can be directly opened on the cylindrical sleeve portion 221. Therefore, the manufacturing process of the sleeve portion 221 is simple and the cost is low.
[0075] Furthermore, during the rotation of the handle body 22 around the hinge shaft 213, the movement trajectory of the contact position between the opening portion 222 and the second rod portion 232 (for example, the movement trajectory of the front edge 222a of the opening portion 222 in a plane perpendicular to the x-direction) may be a part of the circular trajectory formed by the rotation of the sleeve portion 221. Alternatively, the movement trajectory of the contact position between the opening portion 222 and the second rod portion 232 may be concentric with the sleeve portion 221.
[0076] In a specific implementation, continue to refer to Figure 5 , Figure 7 and Figure 8 The sleeve portion 221 may further include a retaining wall 223 extending outward from the front edge 222a of the opening portion 222, and the included angle between the retaining wall 223 and the sleeve portion 221 at the edge 222a may be associated with the rotation angle of the handle body 22 from the first position to the second position.
[0077] Specifically, the retaining wall 223 may extend from the edge 222 a toward a direction away from the ejection mechanism 23 .
[0078] Furthermore, the first position is recorded as the initial position of the handle body 22, and the second position is recorded as the end position of the handle body 22 that can rotate around the hinge axis 213. The angle between the retaining wall 223 and the sleeve portion 221 at the edge 222a can determine the maximum rotation angle of the handle body 22 that can rotate around the hinge axis 213.
[0079] For example, the smaller the included angle between the retaining wall 223 and the sleeve portion 221 at the edge 222a, the larger the maximum rotation angle, that is, the larger the rotation angle of the handle body 22 from the first position to the second position.
[0080] In some embodiments, the angle between the retaining wall 223 and the sleeve portion 221 at the edge 222a may be approximately 90°, and accordingly, the maximum rotation angle of the handle body 22 is approximately 90°. Figure 7When the handle body 22 is in the first position, the retaining wall 223 can be parallel to the horizontal plane. As the handle body 22 rotates, the retaining wall 223 flips backward around the axis of the hinge shaft 213 to be perpendicular to the y direction. At this time, the retaining wall 223 is parallel to the second rod portion 232 and the two are attached to each other. Figure 8 At this point, the handle body 22 is restricted from continuing to rotate clockwise, and the maximum rotation angle of the handle body 22 is about 90°.
[0081] Therefore, the maximum rotation angle of the handle body 22 can be reasonably designed as needed, so that the movement amplitude of the user's hand can be controlled within a reasonable range, further optimizing the user experience.
[0082] In a specific implementation, continue to refer to Figure 5 , Figure 7 and Figure 8 The sleeve portion 221 may further include: a pair of limiting portions 224, which are arranged on both sides of the opening portion 222 along the axial direction (for example, x direction) of the hinge shaft 213 to limit the relative position of the second rod portion 232 and the opening portion 222 in the axial direction of the hinge shaft 213.
[0083] Specifically, the pair of limiting portions 224 may be adapted to form left and right boundaries of the opening 222 along the x-direction.
[0084] Furthermore, the distance between the pair of limiting portions 224 may be substantially equal to the width of the second rod portion 232 along the x-direction.
[0085] Thus, unexpected misalignment between the second rod portion 232 and the sleeve portion 221 during movement is avoided, thereby ensuring reliable transmission of power to the second rod portion 232 .
[0086] In some embodiments, the limiting portion 224 may include walls extending from both sides of the opening 222 in a direction away from the sleeve portion 221, and further, the walls may extend forward to be flush with the retaining wall 223. Thus, a pair of limiting portions 224 can reliably limit the second rod portion 232 throughout the rotation of the handle body 22.
[0087] In a specific implementation, continue to refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The handle body 22 may include a grip portion 225 and a connecting arm 226 , wherein the grip portion 225 is convenient for the user to grip and apply force, and the connecting arm 226 is used to connect the grip portion 225 and the sleeve portion 221 .
[0088] Specifically, the grip portion 225 may be in the shape of an elliptical column extending along the x direction. For example, the front surface and the rear surface of the grip portion 225 may both be arc surfaces, so as to further optimize the hand feeling of the user when gripping.
[0089] Furthermore, the connecting arm 226 may have a certain width along the x-direction to enhance the structural strength.
[0090] For example, the connecting arm 226 may be integrally formed with the sleeve portion 221 .
[0091] For another example, the connecting arm 226 and the gripping portion 225 may be fixed together by screws or the like. Figure 4 , receiving holes 225a may be provided at both ends of the grip portion 225 along the extension direction (e.g., the x direction) on one side facing the handle base 21. Correspondingly, a through hole 226a is provided at the end of the connecting arm 226 close to the grip portion 225. During assembly, a screw passes through the through hole 226a and is fixed to the receiving hole 225a to fix the connecting arm 226 and the grip portion 225 together.
[0092] Therefore, the connecting arm 226 serves as a power arm, the second rod portion 232 serves as a resistance arm, and the axis of the sleeve portion 221 and the hinge shaft 213 coincide as a lever fulcrum. The three cooperate to form a lever structure, which transmits the door opening force applied by the user to the box body 10 to realize the door opening action.
[0093] In a typical application scenario, the user pulls the grip portion 225, and the grip portion 225 rotates around the hinge shaft 213 through the connecting arm 226 and the sleeve portion 221, thereby pushing the ejection mechanism 23 to move toward the box body 10, and the door 11 is pushed open.
[0094] In some embodiments, the connecting arm 226 may include a flat plate perpendicular to the y direction. Further, one end of the connecting arm 226 fixed to the gripper 225 may be bent toward the gripper 225 to form a flange, and the flange may support the boss provided with the receiving hole 225a from below, which is beneficial for positioning during installation and preventing the gripper 225 from falling.
[0095] In some embodiments, continue to refer to Figure 5 , the connecting arm 226 can be located in front of the sleeve portion 221 and tangent to the wall of the sleeve portion 221. Further, the opening portion 222 can be opened in the sleeve portion 221 and extend forward to the connecting arm 226. Thus, the connecting arm 226 is suitable for forming the front boundary of the opening portion 222, that is, the front edge 222a. When the handle body 22 is located in the first position, the end 232a of the second rod portion 232 extending into the opening portion 222 and the rearward surface of the connecting arm 226 can maintain surface-to-surface contact.
[0096] In some embodiments, continue to refer to Figure 7 and Figure 8In the z direction, the connecting arm 226 and the ejection mechanism 23 may be on the same straight line, in other words, the projections of the connecting arm 226 and the ejection mechanism 23 in the y direction at least partially overlap. Thus, the force transmission loss is small.
[0097] Furthermore, the ejection mechanism 23 can be located above the handle body 22. Thus, when the width of the handle assembly 2 as a whole along the x-direction remains unchanged, the spacing between the sleeve portions 221 on both sides is larger, the spacing between the gripping portions 225 is larger, and the user has a better gripping feel. Among them, the top is a relative concept, specifically referring to the side closer to the door 11 relative to the handle body 22 (for example, the upper side). In actual applications, when the handle assembly 2 is located on the left or right side of the door 11, the top refers to the left / right side; when the handle assembly 2 is located on the lower side of the door 11, the top refers to the lower side.
[0098] In some embodiments, when the sleeve portion 221 rotates to push the second rod portion 232 , the two may be in line-surface contact, surface-surface contact, or point-surface contact.
[0099] For example, refer to Figure 7 and Figure 8 The sleeve portion 221 rotates to touch the second rod portion 232 through the edge 222a and then push the latter to move. During this period, the edge 222a and the second rod portion 232 can be in line contact. Therefore, the contact surface between the handle body 22 and the ejection mechanism 23 is larger, and the transmission is more stable.
[0100] In a specific implementation, the length of the connecting arm 226 may be greater than the length of the second rod portion 232. Specifically, the length of the connecting arm 226 may refer to the distance from the sleeve portion 221 to the grip portion 225. Further, the length of the second rod portion 232 may refer to the distance from the end 232a of the second rod portion 232 to the first rod portion 231.
[0101] In this embodiment, the force point (also called the resistance point) is on the second rod 232 (for example, the connection between the second rod 232 and the first rod 231), so the resistance arm is equivalent to the length of the second rod 232, and the force application point (also called the power point) is on the handle body 22 (for example, the grip portion 225), so the power arm is equivalent to the length of the connecting arm 226. Therefore, the power arm is longer than the resistance arm, so that the handle assembly 2 can form a labor-saving lever, and the user can open the door by applying a small force.
[0102] In a specific implementation, continue to refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 The household appliance 1 may further include a stopper 214 disposed close to the hinge shaft 213, and the stopper 214 is used to stop the handle body 22 at the first position.
[0103] Specifically, the blocking portion 214 may extend outward from the hinge shaft 213 to block the handle body 22 when the handle body 22 rotates to the first position.
[0104] Thus, the stopper 214 plays a role of limiting the maximum rotation angle of the handle body 22. For example, it is ensured that the rotation angle of the handle body 22 is basically limited to between 0° and 90°. Furthermore, when the handle body 22 is reset to the first position, the stopper 214 prevents the handle body 22 from excessively moving and colliding with other components of the door body 110 and thus being damaged, which is conducive to extending the service life of the components.
[0105] In some embodiments, the sleeve portion 221 may be located between the stopper 214 and the hinge shaft 213. Specifically, there may be a non-zero gap between the stopper 214 and the hinge shaft 213 to provide enough space for the sleeve portion 221 to be sleeved on the hinge shaft 213 and rotate around the hinge shaft 213. Thus, the stopper 214 and the sleeve portion 221 can function independently without interfering with each other.
[0106] In some embodiments, along the direction in which the handle body 22 rotates toward the first position (by pressing Figure 7 and Figure 8 The blocking portion 214 may be located in front of the connecting arm 226 (viewing angle is counterclockwise rotation).
[0107] Specifically, after the user pulls the handle body 22 to the second position, for example, and then lets go, the handle body 22 automatically returns to the first position under the action of gravity as the force applied to the handle body 22 disappears. When the handle body 22 falls back to the first position, the connecting arm 226 is blocked by the stopper 214 located in the front, and the tendency of the handle body 22 to continue to rotate forward is stopped, so that the handle body 22 is automatically stopped at the first position.
[0108] Thus, the handle body 22 can automatically return to the first position without additional user operation, simplifying the user operation steps and further optimizing the user experience. Furthermore, when the handle body 22 is in the first position, the connecting arm 226 is located in front of the blocking portion 214 in the thickness direction of the door 11 and covers the blocking portion 214, making the front of the door 11 more beautiful.
[0109] In some embodiments, the blocking portion 214 may include a blocking plate 215 extending from a position close to the hinge shaft 213 toward a direction away from the hinge shaft 213 .
[0110] Specifically, along the thickness direction (eg, y direction) of the door 11 , the baffle 215 may be located between the connecting arm 226 and the handle base 21 .
[0111] Furthermore, the baffle 215 may be perpendicular to the y direction. When the handle body 22 is located at the first position, the connecting arm 226 and the baffle 215 may be in surface contact.
[0112] Therefore, the baffle 215 can not only play a stopping role but also serve as a reinforcement to enhance the structural strength of the connecting arm 226 .
[0113] In some embodiments, the blocking portion 214 may further include a connecting portion 216 for connecting the blocking plate 215 and the hinge shaft 213 .
[0114] Specifically, the connecting portion 216 may be arc-shaped, and the curvature of the arc-shaped connecting portion 216 may fit the outer circumferential surface of the hinge shaft 213 .
[0115] For example, the connection portion 216 may be fixed to the side of the hinge shaft 213 facing the rear cover 21a by bonding, welding, etc. The connection portion 216 may be integrally formed with the baffle 215 and extend downward from the lower end of the connection portion 216 .
[0116] Furthermore, the connecting portion 216 can avoid the sleeve portion 221 which is also sleeved on the hinge shaft 213 to avoid interference between the two.
[0117] In a variation, the stopper 214 may include a stopper extending upward from the upper surface of the hinge shaft 2123, and the sleeve portion 221 (eg, the second avoidance portion 227) may be provided at the hinge shaft 2123. Figure 7 and Figure 8 The maximum travel of the counterclockwise rotation of the viewing angle is limited by the block, which can also achieve the stop position of the handle body 22.
[0118] In a specific implementation, the number of the hinge shafts 213 can be two and they are symmetrically arranged on both sides of the handle base 21 along the x direction. Figure 3 A pair of side walls 21b may be symmetrically provided with hinge shafts 213.
[0119] Accordingly, the number of sleeve portions 221 may be two and they are respectively mounted on the hinge shafts 213 on the left and right sides. Similarly, the number of connecting arms 226 may be two, one of which is used to connect the sleeve portion 221 mounted on the left hinge shaft 213 and the left end of the grip portion 225, and the other is used to connect the sleeve portion 221 mounted on the right hinge shaft 213 and the right end of the grip portion 225.
[0120] In a variation, the number of the hinge shaft 213 may also be one, which is disposed at the middle or end of the handle base 21 along the x-direction.
[0121] In practical applications, the number of hinge shafts 213 can be three or even more to further disperse the force, so that the force applied by the ejection mechanism 23 to the box body 10 is more dispersed and uniform, and the door 11 can be ejected smoothly (for example, basically parallel to the x-direction).
[0122] In some embodiments, the length of the grip portion 225 between the pair of connecting arms 226 may be no less than the width of an adult's palm.
[0123] In a specific implementation, continue to refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 A first avoidance portion 217 may be provided on the side of the hinge shaft 213 facing the ejection mechanism 23 , and the sleeve portion 221 and the first avoidance portion 217 together enclose a space for the second rod portion 232 to move along the thickness direction (eg, y direction) of the door 11 .
[0124] Specifically, the upper side of the hinge shaft 213 can be flattened into a platform, and the cavity between the platform and the sleeve portion 221 is suitable for forming the first escape portion 217. The second rod portion 232 pushed by the rotating sleeve portion 221 moves backward above the platform.
[0125] Furthermore, there is a non-zero gap between the end 232a of the second rod 232 extending into the opening 222 and the platform. Therefore, the second rod 232 will not rub against the platform during the forward and backward movement, and the ejection mechanism 23 will be subjected to less friction when moving forward and backward, so that the movement is smoother and the user can open the door with less effort.
[0126] Therefore, the hinge shaft 213 is designed with an adaptive structure to ensure that the second rod portion 232 can move forward and backward smoothly, thereby transmitting the output force of the lever structure to the first rod portion 231 as loss-free as possible.
[0127] In a specific implementation, continue to refer to Figure 5 , Figure 7 and Figure 8 The sleeve portion 221 may be provided with a second avoidance portion 227 communicating with the opening portion 222 , for avoiding the second rod portion 232 moving toward the box body 10 under the push of the sleeve portion 221 .
[0128] Specifically, the second avoidance portion 227 may include an avoidance groove opened along the circumference of the sleeve portion 221 , and the avoidance groove is located behind the opening portion 222 and communicates with the opening portion 222 .
[0129] Furthermore, the avoidance groove penetrates the cylindrical wall of the sleeve portion 221 in the radial direction.
[0130] Furthermore, the length of the escape groove extending in the axial direction is not less than the width of the second rod portion 232. For example, the escape groove extends to the end of the sleeve portion 221 in the axial direction.
[0131] Therefore, the sleeve portion 221 is adaptively designed to give way to the second rod portion 232 , and to reserve sufficient movement space for the second rod portion 232 to move backwards pushed by the rotated sleeve portion 221 .
[0132] In some embodiments, the opposing surfaces of the sleeve portion 221 and the hinge shaft 213 may be relatively smooth to reduce friction when the sleeve portion 221 rotates around the hinge shaft 213 .
[0133] In a specific implementation, continue to refer to Figure 3 , Figure 7 and Figure 8 The handle base 21 may include a guide mechanism 218 disposed on a side of the door 11 and extending along a thickness direction (eg, y direction) of the door 11 , and the guide mechanism 218 is used to guide a movement direction of the first rod portion 231 .
[0134] Specifically, the guide mechanism 218 may include a guide rail 219 extending backward from the upper edge of the rear cover 21 a . The guide rail 219 has a limiting groove that is recessed downward and extends along the y direction to accommodate the first rod portion 231 .
[0135] For example, the width of the limiting groove along the x-direction may be substantially equal to the width of the first rod portion 231 , so as to prevent the first rod portion 231 from shaking during the forward and backward movement along the guide rail 219 .
[0136] Thus, it is ensured that the first rod portion 231 moves along the front-rear direction, and the force applied by the user is transmitted to the box body 10 as loss-free as possible to push open the door 11 .
[0137] In a specific implementation, continue to refer to Figure 2 and Figure 7 The household appliance 1 may further include a reset mechanism 24 for pushing the ejection mechanism 23 in a direction away from the box body 10 so as to return the handle body 22 to the first position. Thus, when the user pulls the handle body 22 to, for example, the second position and then lets go, as the force applied to the handle body 22 disappears, the handle motion system automatically and quickly returns to the first position under the dual effects of gravity and the reset mechanism 24.
[0138] Furthermore, by providing a reset mechanism 24, when the door 11 is in the position of opening the storage chamber 101, the handle body 22 is restored to the first position. Figure 7In the position shown, the end 231a of the first rod portion 231 toward the box body 10 extends out of the door 11 to the minimum extent, and the user is not likely to touch the first rod portion 231 when putting items into the storage chamber 101 or taking items out of the storage chamber 101.
[0139] In some embodiments, the direction of the force generated by the reset mechanism 24 can be parallel to the thickness direction of the door 11 to play a guiding and force balancing role.
[0140] Specifically, when the handle body 22 moves from the first position to the second position, the ejection mechanism 23 is pushed by the rotating sleeve portion 221 to move backward.
[0141] Further, after the handle body 22 leaves the first position, the ejection mechanism 23 begins to be acted upon by the reset mechanism 24. After the user releases the grip portion 225, the ejection mechanism 23 moves forward under the action of the reset mechanism 24, which in turn pushes the sleeve portion 221 to rotate to accelerate the handle body 22 to return to the first position.
[0142] Therefore, the movement direction of the ejection mechanism 23 under the action of the sleeve portion 221 during the rotation of the handle body 22 from the first position to the second position is parallel to but opposite to the movement direction of the ejection mechanism 23 under the action of the reset mechanism 24 during the rotation of the handle body 22 from the second position back to the first position, which is conducive to the rapid switching of the handle body 22 between the first position and the second position.
[0143] In some embodiments, the reset mechanism 24 may include an elastic member 241 , and two ends of the elastic member 241 along the elastic force direction are respectively connected to the handle seat 21 and the second rod portion 232 .
[0144] Specifically, refer to Figure 7 The elastic member 241 may be disposed behind the second rod portion 232 , and the two ends along the elastic force direction may be connected to the rear cover 21 a and the second rod portion 232 , respectively.
[0145] For example, the second rod portion 232 may be provided with a protrusion 243 (eg, Figure 6 As shown), used to fix the end of the elastic member 241.
[0146] For another example, the rear cover 21a may be provided with a receiving groove 242 that is recessed toward the rear (eg, Figure 2 As shown), for receiving the end of the elastic member 241.
[0147] Furthermore, the elastic member 241 may be, for example, a spring.
[0148] Thus, the handle body 22 is indirectly driven to return to the first position through the elastic member 241 to assist in resetting the handle motion system. Specifically, the spring is supported between the handle base 21 and the ejection mechanism 23. When the door 11 is opened, the action force is directly transmitted from the handle body 22 to the ejection mechanism 23, and the reaction force is applied by the spring to the ejection mechanism 23, and then fed back to the handle body 22 through the ejection mechanism 23.
[0149] In a specific implementation, continue to refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 The door 11 may further include a cover plate 115 for covering at least the ejection mechanism 23 from the side. In the example where the handle assembly 2 is disposed on the upper side of the door 11, the cover plate 115 may cover at least a portion of the structure of the handle assembly 2 from above.
[0150] Furthermore, the cover plate 115 may be provided with a notch 116, and the notch 116 may expose the portion of the handle body 110 other than the sleeve portion 221 from the side. For example, in the z direction, the notch 116 at least exposes the portion of the grip portion 225 located between the left and right connecting arms 226. Thus, the user's operating convenience can be improved, and the cover plate 115 is prevented from hindering the user's operation on the handle body 22.
