The door opening and closing assisting apparatus includes at least one elastic member configured such that a contact portion of a free end of the at least one elastic member with the hinge or the front panel of the apparatus is movable from one side of the reference line to the other side of the reference line during opening and closing of the door of the apparatus, so that the door of the apparatus can be subjected to a force at one side or the opposite side of the axis of the rotating shaft, thereby assisting the opening or closing of the door of the apparatus.
Description
Technical Field
The present invention relates to an auxiliary door opening and closing apparatus, and more particularly, to an auxiliary door opening and closing apparatus suitable for a drum type washing machine using a push-push type locking mechanism.
Background
Push-push latching mechanisms (also known as double-push latching mechanisms or push-in latching mechanisms) are mechanisms in which, for example, an inward pushing force can be applied to an open closure member (e.g., a door) to move the closure member from its open position to its closed position, the latching mechanism then holds the closure member in its closed position, and an inward pushing force can likewise be subsequently applied to the latched closure member to initially disengage or release the latching mechanism, which can then be moved to its open position. A push-push latch mechanism is described in the applicant's prior application (application No. 201710536739.8), which is hereby incorporated by reference in its entirety. It should be appreciated that the push-push door latch may be any other configuration of push-push door latch known to those skilled in the art.
The drum type washing machine includes a cabinet, a front panel of which is provided with an opening for putting in and taking out laundry, and a washing machine door connected to the cabinet to open and close the opening. A sealing member is provided around the opening of the front panel for sealing a gap between the door and the opening when the door is closed, so that the washing liquid does not flow out from the gap between the door and the opening of the washing machine when the washing machine is in operation.
In a conventional drum type washing machine using a push-push type locking mechanism, an elastic member is generally provided between a door and a front panel of the washing machine, and the elastic member is used to automatically open the door at a certain angle against an urging force of a sealing member against the door after the locking mechanism is released by applying an inward pushing force to the door at a closed position when the door is opened.
However, the applicant has found that the elastic component in the prior art is arranged so that when the washing machine door in the closed position is pushed inwards, the elastic component generates resistance to the inward movement of the washing machine door, so that the operator needs to increase the force for pushing the door to realize the door opening operation.
Disclosure of Invention
In order to solve at least one of the above problems, at least one object of the present application is to provide an auxiliary opening and closing door apparatus which enables an operator to easily operate a device using a push-push type door lock.
In order to achieve the above object, a first aspect of the present application provides an auxiliary opening and closing door apparatus for a device having a push-push type latch mechanism, comprising:
a hinge having at least one support arm, each of the at least one support arm having one end fixed to a front panel of the appliance and the other end provided with a rotation shaft, wherein a door of the appliance is mounted on the rotation shaft at one side thereof;
at least one elastic member having one end fixed to a door of the device and the other end protruding outward from the door of the device to form a free end, wherein the at least one elastic member is compressed by the free end contacting the hinge or the front panel of the device;
wherein the rotating shaft has an axis, and a reference line passing through the axis and perpendicular to the front panel; and is
Wherein the at least one elastic member is configured such that a contact portion of a free end of the at least one elastic member with the hinge or the front panel of the apparatus is movable from one side of the reference line to the other side of the reference line during opening and closing of the door of the apparatus, so that the door of the apparatus can receive a force at one side or the opposite side of the axis of the rotation shaft.
When the force application center line of the elastic part is positioned at the outer side of the door of the device relative to the rotating shaft reference line, the elastic part can provide auxiliary force when the door is opened, the auxiliary device door is automatically opened to a larger angle, and the automatic door opening of the device is realized. When the center line of the elastic member is located inside the door of the device with respect to the reference line of the rotation axis, the elastic member cooperates with the push-push type door lock to provide an assisting force to assist the push operation of the push-push type door lock, thereby improving the push feeling.

Detailed Description
Various embodiments of the present application will now be described with reference to the accompanying drawings, which form a part hereof. It should be understood that although directional terms such as "front," "rear," "upper," "lower," "left," "right," and the like may be used herein to describe various example structural portions and elements of the application, these terms are used herein for convenience of description only and are to be determined based on the example orientations shown in the drawings. Because the embodiments disclosed herein can be arranged in a variety of orientations, these directional terms are used for purposes of illustration only and are not to be construed as limiting. Wherever possible, the same or similar reference numbers used in this application refer to the same or like parts.
Fig. 1 is a schematic view illustrating a structure of a washing machine 100 using an auxiliary door opening and closing device of the present application, and an internal structure of the washing machine 100 is omitted for clarity. As shown in fig. 1, the washing machine 100 includes a cabinet 110 and a washing machine door 102 coupled to the cabinet 110. The cabinet 110 includes a front panel 101 provided with a door opening 128, through which laundry can be added to or taken out of the washing machine 100. The washing machine door 102 can open or close the door opening 128.
The washing machine door 102 includes a connecting side 132 and an opposite locking side 131. The washing machine door 102 is connected to the front panel 101 at a connection side 132 via a hinge 103, such that the washing machine door can rotate about a rotation axis 210 (not shown in fig. 1, see fig. 5A) of the hinge 103, thereby opening or closing the door opening 128. Although the rotation shaft 210 of the hinge 103 is not shown in fig. 1, the axis 140 of the rotation shaft 210 is shown by a dotted line. The lock side 131 of the washing machine door 102 is provided with a door hook 108, and the door hook 108 is capable of locking the washing machine door 102 to the front panel 101 in cooperation with a push-push latch mechanism (not shown in the drawings) provided in the front panel 101.
The structure of the hinge will be described in detail below with reference to fig. 5A, where fig. 5A shows an embodiment of the hinge.
As shown in fig. 5A, the hinge 103 includes a hinge base 104, and the hinge base 104 is provided with at least one support arm 105 extending outward from the hinge base 104. One end of the support arm 105 is fixed to the hinge base 104 and the other end is provided with a rotation shaft 210 for connecting the washing machine door 102. The rotation axis 210 is disposed substantially parallel to the hinge base 104.
In the example shown in fig. 5A, the support arm 105 is made up of interconnecting a first arm 517 and a second arm 518. The first arm 517 is connected to the hinge base 104, one end of the second arm 518 is connected to the first arm 517, and the other end is provided with the rotating shaft 210. The first arm 517 is substantially perpendicular to the hinge base 104, and the second arm 518 is substantially parallel to the hinge base 104 and substantially perpendicular to the first arm 517, such that the support arm 105 is substantially L-shaped. The L-shaped support arm 105 allows the washing machine door 102 to have a large opening angle. The number of the support arms 105 may be one or more. In the example illustrated in fig. 1 and 5A, the hinge 103 has two support arms 105 arranged in parallel, the two support arms 105 being spaced apart by a distance. The two support arms 105 are provided with separate rotation shafts 210, respectively, and the two rotation shafts 210 are required to satisfy the condition of being coaxial, and the common axis thereof is indicated by a dotted line 140 in fig. 1 and 5A.
The hinge base 104 also has a contact 546. When the hinge 103 has two support arms 105, the contact 546 is located between the two support arms 105.
Further, the hinge base 104, the first arm 517, and the second arm 518 may be integrally formed. The hinge base 104 has mounting portions 545 at both ends thereof, and the hinge base 104 can be fixed to the front panel 101 by the mounting portions 545, and the hinge base 104 and the front panel 101 can be fixed by caulking or the like, as an example. In other examples, the mounting portions may not be provided at both ends of the hinge base 104 or on the hinge base 104 as long as the fixed connection of the hinge 103 and the front panel 101 can be ensured.
Still referring to fig. 1. As shown in fig. 1, the washing machine 100 further includes at least one elastic member 106, and the elastic member 106 is disposed on a connection side 132 of the washing machine door 102 (i.e., a side of the washing machine door facing the door opening 128). The elastic member 106 has elasticity and can be compressed to contract or restored to extend. Although the example shown in fig. 1 shows only one elastic member 106, it should be noted that the number of elastic members 106 may be more than one.
One end of the elastic member 106 is fixedly mounted on the washing machine door 102, and the other end of the elastic member 106 extends outward from the connecting side 132 of the washing machine door 102 to form a free end 156. The elastic member 106 can rotate about the rotation axis 210 as the washing machine door 102 rotates about the rotation axis 210. The elastic member 106 is configured such that, during rotation of the washing machine door 102, the free end 156 of the elastic member 106 can contact the contact portion 546 of the hinge 103 within a range where the washing machine door 102 is at an angle to the front panel 101, so that the elastic member 106 can be compressed to apply an elastic pushing force to the hinge 103 and receive a compression force corresponding to the elastic pushing force, and since the elastic member 106 is fixedly mounted on the washing machine door 102, the washing machine door 102 can receive a force corresponding to the compression force. When the hinge 103 has two support arms 105 (as shown in fig. 1 and 5A), the mounting position of the resilient member 106 on the washing machine door 102 is also located between the two support arms 105, so that the free end 156 of the resilient member 106 can contact the contact portion 546 of the hinge base 104 located between the two support arms 105.
It is noted that although in the example shown in fig. 1, the free end 156 of the elastic member 106 is in contact with the contact portion 546 of the hinge base 104 so that the elastic member 106 is compressed, the free end 156 of the elastic member 106 may be compressed not by the contact portion 546 of the hinge base 104 but by a corresponding portion of the front panel 101, which also enables the elastic member 106 of the present application to operate as intended. In this case, the corresponding portion of the front panel 101 is not blocked by the contact portion 546 of the hinge base 104, or the contact portion 546 is not provided on the hinge 103.
Fig. 2A is a top view of the washing machine shown in fig. 1 in a door-closed state, and fig. 2B is a partially enlarged and partially sectional view of a portion a of fig. 2A, in which a section of the elastic member 106 and the hinge 103 in a direction perpendicular to the front panel 101 is shown. As shown in fig. 2B, the axis 140 of the rotating shaft 210 is a point in the perspective of fig. 2B. The free end 156 of the elastic member 106 has a central protrusion 158, and the free end 156 of the elastic member 106 has a contact portion 159 contacting the hinge 103 or the front panel 101, and the contact portion 159 can be regarded as a point of action of the elastic member 106 with the hinge 103 or the front panel 101. In the state shown in fig. 2A and 2B, the contact portion 159 is located on the center protrusion 158. The central protrusion 158 has a smooth surface to facilitate contact of the free end 156 of the resilient member 106 with the hinge 103 or the front panel 101.
As also shown in fig. 2B, there is a reference line 241 through the axis 140 and perpendicular to the front panel 101. The elastic member 106 is configured such that a contact portion 159 of the free end 156 of the elastic member 106 with the hinge 103 or the front panel 101 can move from one side of the reference line 241 to the other side of the reference line 241 during the opening and closing of the washing machine door 102, so that the washing machine door 102 can receive a force at one side or the opposite side of the axis 140 of the rotation shaft 210. This will be described in detail below in connection with 2A, 2B, 3A, 3B, 4A and 4B. When the washing machine door 102 is closed (i.e., the state shown in fig. 2B), the contact portion 159 of the free end 156 of the elastic member 106 and the hinge 103 or the front panel 101 is located on the side of the reference line 241 away from the door hook 108 (i.e., the left side of the reference line 241 shown in fig. 2B).
Further, the distance H between the free end 156 of the elastic member 106 and the contact portion 159 of the hinge 103 or the front panel 101 and the reference line 241 is set small so that the contact portion 159 of the free end 156 of the elastic member 106 and the hinge 103 or the front panel 101 can move from one side of the reference line 241 to the other side of the reference line 241. According to an example of the invention, the distance H of the free end 156 of the elastic member 106 from the hinge 103 or the contact portion 159 of the front panel 101 from the reference line 241 is 3-5 mm.
Thus, the above-described arrangement of the elastic member 106 enables the washing machine door 102 to be acted upon by the elastic member 106 on the side of the axis 140 away from the door hook 108 (i.e., the left side of the axis 140 shown in fig. 2B) and also enables the washing machine door 102 to be acted upon on the side of the rotation axis 140 close to the door hook 108 (i.e., the right side of the axis 140 shown in fig. 2B) during the opening or closing of the washing machine door 102. As the washer door 102 rotates about the axis 140, when the washer door 102 is subjected to a force on the side of the axis 140 away from the door hook 108 (i.e., to the left of the axis 140 as shown in fig. 2B), the force can assist the washer door 102 in closing; and when the washing machine door 102 is subjected to a force on the side of the axis 140 near the door hook 108 (i.e., to the right of the axis 140 as shown in fig. 2B), the force can assist the washing machine door 102 in opening.
The process of using the elastic member 106 to assist opening and closing the door of the washing machine door 102 in fig. 1 is described below with reference to fig. 2A, 2B, 3A, 3B, 4A and 4B.
Fig. 3A and 4A show top views of the washing machine shown in fig. 1 in two different open angle states of the washing machine door 102, respectively. Fig. 3B and 4B show a partial enlargement and a partial sectional view of the portion a of fig. 3A and 4A, respectively, similar to fig. 2B, in which the elastic member 106 and the hinge 103 are shown in section in a direction perpendicular to the front panel 101.
Specifically, the washing machine door 102 sequentially passes through the states shown in fig. 2A, 3A and 4A during the opening process, and the washing machine door 102 sequentially passes through the states shown in fig. 4A, 3A and 2A during the closing process. Also, during the state shown in fig. 2A to 4A or the state shown in fig. 4A to 2A, the free end 156 of the elastic member 106 always abuts against the contact portion 546 of the hinge base 104, so that the elastic member 106 is always in a compressed state, keeps applying a pushing force to the hinge base 104, and applies a corresponding force to the washing machine door 102.
As described above, in the closed state of the washing machine door 102 shown in fig. 2B, the contact portion 159 of the free end 156 of the elastic member 106 with the hinge 103 is located on the side of the reference line 241 away from the door hook 108 (i.e., on the left side of the reference line 241 shown in fig. 2B). At this time, the elastic member 106 receives a compressive force F from the contact portion 546 of the hinge 1030And subject the washer door 102 to a corresponding force. Compressive force F0Is substantially perpendicular to the contact portion 546 of the hinge 103. As can be seen in FIG. 2B, the washer door 102 is now subjected to a compressive force F on the side of the axis 140 remote from the door hook 108 (i.e., to the left of the axis 140 as viewed in FIG. 2B)0Corresponding force. As the washing machine door 102 rotates about the axis 140, the washing machine door 102 experiences a compressive force F on the side of the axis 140 away from the door hook 108 (i.e., to the left of the axis 140 as shown in FIG. 2B)0The corresponding force will tend to move the lock side 131 of the washing machine door where the door hook 108 is mounted toward the front panel 101.
As shown in fig. 3A and 3B, the washing machine door 102 is in an open state, and the washing machine door 102 and the front panel 101 are at a critical angle β, for example, about 2 °, at which the door hook 108 of the washing machine 100 is just about to be in contact with or separated from the push-push type latch mechanism, at which critical angle the contact portion 159 of the free end 156 of the elastic member 106 and the hinge 103 is just above the reference line 241, and the elastic member 106 receives a compressive force F from the contact portion 546 of the hinge 103 from the elastic member 1061Coincides with the reference line 241. Since the reference line 241 extends through the axis 140 of the rotating shaft 210 and the washing machine door 102 rotates about the axis 140, the compressive force F1The washing machine door 102 is not rotated.
As shown in FIGS. 4A and 4B, the washing machine door 102 is in an open state and the washing machine door 102 is at an angle greater than the critical angle β with respect to the front panel 101 at which time the contact portion 159 of the free end 156 of the resilient member 106 with the hinge 103 has crossed the reference line 241, rotating from the side of the reference line 241 remote from the door hook 108 (i.e., the left side of the reference line 241 shown in FIG. 4B) to the side of the reference line 241 proximate to the door hook 108 (i.e., the right side of the reference line 241 shown in FIG. 4B). at this time, the resilient member 106 is subjected to a compressive force F from the contact portion 546 of the hinge 103 at which the force F is applied2And subject the washer door 102 to a corresponding force. Compressive force F2Is substantially perpendicular to the contact portion 546 of the hinge 103. As can be seen in FIG. 4B, the washer door 102 is now compressed on the side of the axis 140 adjacent the door hook 108 (i.e., to the right of the axis 140 as viewed in FIG. 4B)Force F2Corresponding force. As the washing machine door 102 rotates about the axis 140, the washing machine door 102 is forced on the side of the axis 140 that is adjacent to the door hook 108 (i.e., the right side of the axis 140 as shown in fig. 4B), which tends to move the lock side 131 of the washing machine door on which the door hook 108 is mounted away from the front panel 101.
During opening of the washer door 102, the operator first applies an inward pushing force to the washer door 102 in the closed state (as shown in fig. 2A and 2B) at the lock side 131 of the washer door 102 to unlock the door hook 108 from the push-push latch mechanism, thereby unlocking the washer door 102. this process is also referred to as an unlocking process, in which, since the washer door 102 is subjected to a force on the side of the axis 140 remote from the door hook 108 (i.e., to the left of the axis 140 shown in fig. 2B), which force assists the action of the operator pushing the washer door inward, the operator is able to effect the unlocking process with less force. after the washer door 102 is unlocked, although the washer door 102 is still subjected to a force on the side of the axis 140 remote from the door hook 108 (i.e., to the left of the axis 140 shown in fig. 2B), the washer door 102 is able to open an angle due to greater inertial force-after the washer door 102 is unlocked, the angle is greater than the critical angle shown in fig. 3A and 3B, the washer door 102 is opened to an angle as shown by contacting the initial door 102B, which is no longer exposed to the hinge component 354, such as the hinge component α, which is exposed to the initial contact of the door 102, such as indicated by an expected angle α.
When the washing machine door 102 rotates to less than the critical angle β with the front panel 101, the washing machine door 102 will be subjected to a force on the side of the axis 140 away from the door hook 108 (i.e., the left side of the axis 140 shown in FIG. 2B), which will cause resistance to the door closing operation at the lock side 131 of the washing machine door, but which will assist the door closing operation of the operator, so that the operator can still bring the washing machine door 102 to the closed state with less operating force and the washing machine door 102 will remain in the closed state.
Thus, the present application provides an auxiliary door opening and closing device suitable for an apparatus using a push-push type latching mechanism, which can assist the washing machine door 102 to be closed when the washing machine door 102 is opened, and can assist the washing machine door 102 to be opened when the washing machine door is closed, by the provision of the elastic member 106.
Fig. 5B and 5C show another embodiment of a hinge. As shown in fig. 5B, the hinge 103 further includes a hinge boss 511. The hinge bushing 511 is sleeved on the rotation shaft 210 and is maintained relatively fixed with respect to the washing machine door 102, so that the position of the washing machine door 102 with respect to the rotation shaft 210 can be restricted by restricting the relative movement of the hinge bushing 511 and the rotation shaft 210.
The hinge bushing 511 is specifically configured as shown in fig. 5C, the rotation shaft 210 is provided with a protrusion 512 extending outward from the outer surface of the rotation shaft 210, and the hinge bushing 511 is provided with a section of recess 513 engaged with the protrusion 512, when the washing machine door 102 rotates around the rotation shaft 210, the hinge bushing 511 also rotates around the rotation shaft 210, the hinge bushing 511 may be made of a material having a certain elasticity, such as plastic, at this time, when the washing machine door 102 rotates within a certain angle range, the hinge bushing 511 is in clearance fit with the rotation shaft 210, a small force can move the protrusion 512 on the rotation shaft within the recess 513 on the hinge bushing, and when the washing machine door 102 rotates beyond the certain angle range, the hinge bushing 511 is in interference fit with the rotation shaft 210, and a large external force is required to continue to rotate the hinge bushing 511 and the washing machine door 102, thereby, the automatic opening angle of the washing machine door 102 can be limited within a desired angle α, and cannot be completely opened due to inertia.
As shown in FIG. 6, the surface of the hinge base 104 of the hinge 103 further comprises a slope 615, the slope 615 is connected to the end of the contact portion 546 and is used for contacting the free end 156 of the elastic component 106 and blocking the free end of the elastic component 106, so that the free end 156 of the elastic component 106 is contacted with the slope 615, and an external force is needed to compress the elastic component 106 to enable the washing machine door 102 to continue rotating, therefore, the automatic opening angle of the washing machine door 102 can be limited within a desired angle α without being completely opened due to inertia.
The specific structure of the elastic member 106 may be an elastic object with one end fixed and the other end free, and has a certain stroke capable of being compressed and restored, such as a spring button or the like. The present application does not limit the specific structure of the elastic member 106, but for better explaining the inventive content of the present application, an example of the structure of the elastic member 106 is given in fig. 7.
As shown in fig. 7, the resilient member 106 includes a movable sleeve 722, the movable sleeve 722 having an open end 721 and a closed end 725 forming a pocket 727 therebetween. With the closed end forming the free end 156 of the resilient member 106. The open end 721 can engage the washer door 102 such that the movable sleeve 722 can move relative to the washer door 102, but does not fall out of the washer door 102.
Specifically, the washing machine door 102 is provided with a hole 765 on the surface thereof for the movable sleeve 722 to pass through, and the movable sleeve 722 extends into the washing machine door 102 through the hole 765. Wherein the open end of the movable sleeve 722 is provided with a flange 759, and the outer contour of the flange 759 is slightly larger than the outer contour of the hole 765, so that the moving stroke of the movable sleeve 722 can be limited, and the movable sleeve 722 can not be outwards removed from the hole 765 when moving relative to the washing machine door 102.
