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
A push-push latch mechanism (also known as a double push latch mechanism or push latch mechanism) is a mechanism in which, for example, an inward push 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, then the latch mechanism holds the closure member in its closed position, and then an inward push force can likewise be applied to the latched closure member to initially disengage or release the latch mechanism, and then the closure member can be moved to its open position. A push-push latch mechanism is described in the applicant's prior application (application number 201710536739.8), which is incorporated herein by reference in its entirety. It should be appreciated that the push-push door lock may be of any other configuration known to those skilled in the art.
The drum type washing machine includes a cabinet having an opening provided on a front panel thereof for laundry to be put in and taken out, 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 washing liquid does not flow out of the gap between the door and the opening of the washing machine when the washing machine is operated.
In the conventional drum type washing machine using the push-push type locking mechanism, an elastic member is generally provided to be clamped between the washing machine door and the front panel, for automatically opening the washing machine door by a certain angle against the force of the sealing member against the washing machine door by the elastic force of the elastic member after the locking mechanism is released by applying an inward pushing force to the washing machine door in the closed position when the door is opened.
However, the applicant has found that the provision of the resilient member in the prior art causes the resilient member to resist inward movement of the washing machine door when the door is pushed inwardly in the closed position, thereby requiring an operator to increase the force with which the door is pushed to effect the door opening operation.
Disclosure of Invention
In order to solve at least one of the above problems, it is at least one object of the present application to provide an auxiliary door opening and closing device that enables an operator to easily operate an apparatus using a push-push type door lock.
To achieve the above object, a first aspect of the present application provides an auxiliary door opening and closing device for an apparatus having a push-push type locking mechanism, comprising:
a hinge having at least one support arm, one end of each of the at least one support arm being fixed to a front panel of the apparatus, the other end being provided with a rotation shaft, wherein a door of the apparatus is mounted on the rotation shaft at one side thereof;
at least one elastic member having one end fixed to the door of the apparatus and the other end protruding outwardly from the door of the apparatus to form a free end, wherein the at least one elastic member is compressed by the free end being in contact with the hinge or the front panel of the apparatus;
wherein the rotating shaft has an axis, passes through the axis and is perpendicular to the front panel and has a reference line; and is also provided with
Wherein the at least one resilient member is configured such that during opening and closing of the door of the device, a contact of a free end of the at least one resilient member with the hinge or a front panel of the device is movable from one side of the reference line to the other side of the reference line to enable the door of the device to be acted upon on one side or the opposite side of the axis of the rotation shaft.
When the force application center line of the elastic component is positioned at the outer side of the door of the equipment relative to the rotating shaft reference line, the elastic component can provide auxiliary force when the door is opened, the door of the auxiliary equipment is automatically opened to a larger angle, and the automatic door opening of the equipment is realized. And when the force application center line of the elastic component is positioned at the inner side of the door of the equipment relative to the reference line of the rotating shaft, the elastic component is matched with the push-push type door lock to provide auxiliary force to assist the pressing operation of the push-push type door lock, so that the pressing hand feeling is improved.

Detailed Description
Various embodiments of the present application are described below with reference to the accompanying drawings, which form a part hereof. It is to be understood that, although directional terms, such as "front", "rear", "upper", "lower", "left", "right", etc., may be used in this application to describe various example structural portions and elements of the present application, these terms are used herein for convenience of description only and are determined based on the example orientations shown in the drawings. Because the embodiments disclosed herein may be arranged in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. Wherever possible, the same or similar reference numbers are used throughout this application to refer to the same parts.
Fig. 1 shows a schematic structure of a washing machine 100 using the auxiliary door opening and closing device of the present application, and the internal structure of the washing machine 100 is omitted for clarity of illustration. 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 or removed to or from the washing machine 100 through the door opening 128. The washing machine door 102 may open or close the door opening 128.
The washing machine door 102 includes a connecting side 132 and an opposite lock side 131. Wherein the washing machine door 102 is connected to the front panel 101 at the connection side 132 by means of a hinge 103 such that the washing machine door can be rotated 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 in phantom. The lock side 131 of the washing machine door 102 is provided with a door hook 108, the door hook 108 being capable of locking the washing machine door 102 to the front panel 101 in cooperation with a push-push latch mechanism (not shown) provided in the front panel 101.
The structure of the hinge is described in detail below in conjunction with fig. 5A, wherein fig. 5A illustrates one embodiment of the hinge.
As shown in fig. 5A, the hinge 103 includes a hinge base 104, and at least one support arm 105 extending outwardly from the hinge base 104 is provided on 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 coupling with the washing machine door 102. The rotational 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 a first arm 517 and a second arm 518 interconnected. Wherein the first arm 517 is connected to the hinge base 104, and the second arm 518 has one end connected to the first arm 517 and the other end provided with the rotation shaft 210. The first arm 517 is substantially perpendicular to the hinge base 104, while 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 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 each provided with a separate rotation shaft 210, which rotation shafts 210 are required to satisfy the coaxial condition, the common axis of which is indicated by the broken line 140 in fig. 1 and 5A.
The hinge base 104 also has a contact portion 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 as an example, the hinge base 104 and the front panel 101 can be fixed by caulking or the like. 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 see fig. 1. As shown in fig. 1, the washing machine 100 further includes at least one resilient member 106, the resilient member 106 being disposed on a connection side 132 of the washing machine door 102 (i.e., the side of the washing machine door facing the door opening 128). The elastic member 106 has elasticity and can be compressed to shorten or recover to lengthen. Although the example shown in fig. 1 shows only one elastic member 106, it is noted that the number of elastic members 106 may be more than one.
One end of the resilient member 106 is fixedly mounted to the washing machine door 102 and the other end of the resilient member 106 extends outwardly from the attachment side 132 of the washing machine door 102 to form a free end 156. The elastic member 106 can rotate around the rotation shaft 210 as the washing machine door 102 rotates around the rotation shaft 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 of a certain angle of the washing machine door 102 with the front panel 101, so that the elastic member 106 can be compressed, thereby applying an elastic pushing force to the hinge 103 and receiving 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 be subjected to 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 elastic 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 elastic member 106 can contact the contact portion 546 on 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 on the hinge base 104 such 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 on 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 function as intended. In this case, the corresponding portion of the front panel 101 is not caught by the contact portion 546 on 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 of fig. 1 in a door-closed state, and fig. 2B is a partially enlarged and partially cross-sectional view of a portion a of fig. 2A, in which a cross 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 rotary shaft 210 is one point in the perspective of fig. 2B. The free end 156 of the resilient member 106 has a central protrusion 158 and the free end 156 of the resilient member 106 has a contact portion 159 that contacts the hinge 103 or the front panel 101, which contact portion 159 can be considered as the point of action of the resilient 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 protruding portion 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 front panel 101.
As also shown in fig. 2B, there is a reference line 241 passing through the axis 140 and perpendicular to the front panel 101. The elastic member 106 is configured such that the contact portion 159 of the free end 156 of the elastic member 106 with the hinge 103 or the front panel 101 can be moved 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 be subjected to a force on 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. Wherein, 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 at a side of the reference line 241 away from the door hook 108 (i.e., a left side of the reference line 241 shown in fig. 2B).
Further, the distance H between the contact portion 159 of the free end 156 of the elastic member 106 and 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 one example of the invention, the free end 156 of the elastic member 106 is 3-5mm from the hinge 103 or the contact 159 of the front panel 101 from the reference line 241.
Thus, the above-described arrangement of the resilient member 106 allows the resilient member 106 to apply a force to the washing machine door 102 on a side of the axis 140 that is remote from the door hook 108 (i.e., the left side of the axis 140 shown in FIG. 2B) and to apply a force to the washing machine door 102 on a side of the axis of rotation 140 that is proximate to the door hook 108 (i.e., the right side of the axis 140 shown in FIG. 2B) during opening or closing of the washing machine door 102. As washing machine door 102 rotates about axis 140, when washing machine door 102 is subjected to a force on the side of axis 140 that is distal from door hook 108 (i.e., the left side of axis 140 shown in fig. 2B), the force can assist in closing washing machine door 102; and when the washer door 102 is subjected to a force 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. 2B), the force can assist in opening the washer door 102.
The following describes the process of opening and closing the door using the elastic member 106 by the washing machine door 102 of fig. 1 in conjunction with fig. 2A, 2B, 3A, 3B, 4A and 4B.
Fig. 3A and 4A respectively show top views of the washing machine shown in fig. 1 in two different open angle states of the washing machine door 102. Similar to fig. 2B, fig. 3B and 4B show a partial enlargement and a partial cross-sectional view of the portion a of fig. 3A and 4A, respectively, in which the elastic member 106 and the hinge 103 are shown in a cross 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. And, 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 door 102 of the washing machine.
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 and the hinge 103 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). At this time, the elastic member 106 receives a compressive force F from the contact portion 546 of the hinge 103 0 And subject the washing machine door 102 to a corresponding force. Compression force F 0 Is oriented substantially perpendicular to the contact portion 546 of the hinge 103. As can be seen in fig. 2B, the washing machine 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., the left side of the axis 140 shown in fig. 2B) 0 Corresponding acting force. As the washing machine door 102 rotates about the axis 140, the washing machine door 102 is subjected to a compressive force F on a side of the axis 140 that is remote from the door hook 108 (i.e., the left side of the axis 140 shown in fig. 2B) 0 The corresponding force will cause the lock side 131 of the washing machine door to which the door hook 108 is mounted to have a tendency to move 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 makes a critical angle β, for example, about 2 ° with the front panel 101. At this time, the door hook 108 of the washing machine 100 is just about to come into contact with or separate from the push-push type locking mechanism. At this critical angle, the elastic member 106 is freeThe contact 159 of the end 156 with the hinge 103 is located just above the reference line 241 and the elastic member 106 is subjected to the compressive force F from the contact 546 of the hinge 103 1 Is coincident with reference line 241. Since reference line 241 extends through axis 140 of rotary shaft 210 and washing machine door 102 rotates about axis 140, compression force F 1 No rotation of the washing machine door 102 occurs.
As shown in fig. 4A and 4B, the washing machine door 102 is in an open state, and the washing machine door 102 makes an angle greater than the critical angle β with the front panel 101. At this time, the contact portion 159 of the free end 156 of the elastic member 106 and the hinge 103 has passed over the reference line 241, and is rotated from 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. 4B) to the side of the reference line 241 near the door hook 108 (i.e., the right side of the reference line 241 shown in fig. 4B). At this time, the elastic member 106 receives the compressive force F from the contact portion 546 of the hinge 103 2 And subject the washing machine door 102 to a corresponding force. Compression force F 2 Is oriented substantially perpendicular to the contact portion 546 of the hinge 103. As can be seen in fig. 4B, the washing machine door 102 is now subjected to a compressive force F on the side of the axis 140 that is adjacent to the door hook 108 (i.e., the right side of the axis 140 shown in fig. 4B) 2 Corresponding acting force. As the washing machine door 102 rotates about the axis 140, the force exerted by the washing machine door 102 on the side of the axis 140 that is closer to the door hook 108 (i.e., the right side of the axis 140 shown in fig. 4B) tends to move the lock side 131 of the washing machine door that mounts the door hook 108 away from the front panel 101.
During the opening of the door 102, an operator first applies an inward pushing force on the door 102 (shown in fig. 2A and 2B) in a closed state at the lock side 131 of the door 102 to unlock the door hook 108 from the push-push latch mechanism, thereby unlocking the door 102. This process is also referred to as an unlocking process, in which, as the washing machine door 102 is subjected to a force on the side of the axis 140 that is remote from the door hook 108 (i.e., the left side of the axis 140 shown in fig. 2B), the force assists the operator in pushing the washing machine door inward, so that the operator can perform the unlocking process with less force. After the washing machine door 102 is unlocked, the washing machine door 102 can open at an angle due to the greater inertial force, although the washing machine door 102 will still be forced on the side of the axis 140 that is remote from the door hook 108 (i.e., the left side of the axis 140 shown in fig. 2B). When the door is opened at an angle greater than the critical angle shown in fig. 3A and 3B, the door 102 will be forced on the side of the axis 140 adjacent the hook 108 (i.e., the right side of the axis 140 shown in fig. 4B) as shown in fig. 4B until the resilient member 106 returns to its original length without abutting the contact portion 546 of the hinge 103. At this point, the washing machine door 102 will open to the desired angle α (e.g., 35 °).
During the closing of the washing machine door 102, an operator first applies an inward pushing force on the washing machine door 102 in an open state at the lock side 131 of the washing machine door 102. In the range of the desired angle alpha to the critical angle beta of the front panel 101, the washing machine door 102 will be exposed to a force on the side of the axis 140 near the door hook 108 (i.e., the right side of the axis 140 shown in fig. 4B) as shown in fig. 4B, which will not significantly affect the door closing force. When the washing machine door 102 is rotated to less than the critical angle β with the front panel 101, the washing machine door 102 will be forced on the side of the axis 140 that is remote from the door hook 108 (i.e., the left side of the axis 140 shown in fig. 2B). At this time, since the door hook 108 comes into contact with the push-push type locking mechanism, a resistance is generated to the door closing operation at the lock side 131 of the washing machine door, but the force acts as an assist to the operator's door closing operation, so that the operator can still bring the washing machine door 102 to the closed state with a small operation force. And this force then helps to maintain the washing machine door 102 in a closed condition.
Thus, the present application provides an auxiliary door opening and closing device suitable for an apparatus using a push-push type locking mechanism, which is capable of not only assisting the closing of the washing machine door 102 when the washing machine door 102 is opened, but also assisting the opening of the washing machine door 102 when the washing machine door is closed, by the provision of the elastic member 106.
Fig. 5B and 5C illustrate another embodiment of a hinge. As shown in fig. 5B, the hinge 103 further includes a hinge sleeve 511. The hinge sleeve 511 is sleeved on the rotation shaft 210 and is kept relatively fixed 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 sleeve 511 and the rotation shaft 210.
As shown in fig. 5C, the hinge sleeve 511 has a specific structure, in which a protrusion 512 extending outward from an outer surface of the rotation shaft 210 is provided on the rotation shaft 210, and a recess 513 matching the protrusion 512 is provided on an inner surface of the hinge sleeve 511 sleeved on the rotation shaft 210. When the washing machine door 102 rotates around the rotation shaft 210, the hinge shaft housing 511 also rotates around the rotation shaft 210. The hinge shaft housing 511 may be made of a material having a certain elasticity, such as plastic. At this time, when the door 102 of the washing machine is rotated within a certain angle range, the hinge sleeve 511 is in clearance fit with the rotation shaft 210, and the protrusion 512 on the rotation shaft can be moved in the recess 513 on the hinge sleeve with a small force. When the door 102 is rotated beyond this range, the hinge sleeve 511 is in interference fit with the rotation shaft 210, and a large external force is required to rotate the hinge sleeve 511 and the door 102. Thus, the angle at which the washing machine door 102 is automatically opened can be limited to the desired angle α without being completely opened due to inertia.
A schematic structural view of a third embodiment of the hinge is shown in fig. 6. As shown in fig. 6, the surface of the hinge base 104 of the hinge 103 also includes a ramp 615. A ramp 615 is connected to the end of the contact portion 546 for contacting the free end 156 of the resilient member 106 and blocking the free end of the resilient member 106. So that the free end 156 of the resilient member 106, when contacting the ramp 615, requires an external force to compress the resilient member 106 to allow the washing machine door 102 to continue to rotate. Thus, the angle at which the washing machine door 102 is automatically opened can also be limited within the desired angle α without being completely opened due to inertia.
The specific structure of the elastic member 106 may be an elastic body with either end fixed and the other end free, and having a certain stroke that can be 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 a clearer explanation of 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, thereby forming a cavity 727 therebetween. Wherein the closed end forms the free end 156 of the resilient member 106. The open end 721 can mate with the washing machine door 102 such that the movable sleeve 722 can move relative to the washing machine door 102, but cannot be disengaged from the washing machine door 102.
Specifically, the surface of the washing machine door 102 is provided with a hole 765 through which the movable sleeve 722 passes, the movable sleeve 722 extending into the washing machine door 102 through said hole 765. The opening 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 movement stroke of the movable sleeve 722 can be limited, and the movable sleeve 722 cannot be outwards separated from the hole 765 when moving relative to the door 102 of the washing machine.
The elastic member 106 further includes a spring 720, one end of the spring 720 is inserted into the cavity 727 of the movable sleeve 722 from the open end of the movable sleeve 722, and the other end is fixed in the washing machine door 102. Thus, the movable sleeve 722 can also be compressed or restored upon movement relative to the washing machine door 102.
In the example shown in fig. 7, a base 763 and a support post 762 are provided within the washing machine door 102. Wherein the spring 720 is sleeved on the support column 762 and abuts against the base 763 such that one end of the spring 720 is fixed inside the washing machine door 102 and the direction in which the spring 720 is compressed is defined by the support column 762.
Although the present application will be described with reference to the specific embodiments shown in the drawings, it should be understood that many variations of the anchoring components of the present application are possible without departing from the spirit and scope and the background of the teachings of the present application. Those of ordinary skill in the art will also recognize that there are different ways to alter the arrangement of the embodiments disclosed herein, and are within the spirit and scope of the present application and the claims.
