[0039] Embodiment 1
[0040] See also Figures 1 to 5As shown, the door pull rope structure provided by the present application can be installed between the device body 101 and the door 102 of electrical equipment such as a dishwasher. The device body 101 and the door 102 are hinged, and the door 102 can be opened automatically or manually so that the user can place the tableware to be washed into the device body 101. After placing the tableware to be washed, close the door 102, and the dishwasher can execute the washing program. After the tableware is washed, without adding a driving device, in order to enable the door 102 to automatically open a certain gap to allow the hot and humid air in the device body 101 to be discharged, the present application sets a door pull rope structure between the device body 101 and the door 102.
[0041] Specifically, the door pull rope structure includes an elastic pull rope 103, a pulley 104 and a telescopic assembly 105. The pulley 104 is connected to the device body 101, one end of the elastic pull rope 103 is connected to the device body 101, the middle part of the elastic pull rope 103 is wound around the pulley 104, and the other end of the elastic pull rope 103 is connected to the door 102. The telescopic assembly 105 is arranged between the elastic pull rope 103 and the door 102. When the washing program of the dishwasher is finished, the device body 101 and the door 102 are unlocked, and the door 102 is subjected to the action of gravity so that the door 102 can swing relative to the device body 101, and the force of the door 102 swinging outward (the component of gravity) can pull the telescopic assembly 105 to extend. During the extension of the telescopic component 105, the elastic force of the elastic pull rope 103 does not take effect until the telescopic component 105 is extended to its longest length. At this time, the elastic force applied by the elastic pull rope 103 to the door 102, the supporting force of the hinge 108 on the door 102 and the gravity of the door 102 are in a balanced state, so that the door 102 can hover at a preset position, and a gap is formed between the door 102 and the device body 101.
[0042] The door pull rope structure provided in the present application can automatically open the door 102 of the dishwasher after the cleaning program of the dishwasher is completed, only through a simple mechanical structure, so that a gap is formed between the door 102 and the device body 101, so that moisture inside the dishwasher can escape, thereby reducing the cost of the dishwasher and the power consumption during operation of the dishwasher.
[0043] In an optional scheme of this embodiment, a hinge assembly 107 is arranged between the device body 101 and the box door 102, and the hinge assembly 107 includes a hinge 108 and a hinge fixing member 109, and the hinge 108 can swing relative to the hinge fixing member 109; the hinge fixing member 109 is connected to the device body 101, and the pulley 104 is installed on the hinge fixing member 109; the hinge 108 is connected to the box door 102, and the telescopic assembly 105 is connected to the hinge 108.
[0044] In this embodiment, the hinge fixing member 109 is installed on the device body 101 so that the hinge fixing member 109 remains fixed. The hinge 108 is installed on the box door 102, and the hinge 108 can swing relative to the hinge fixing member 109, so that the box door 102 can swing relative to the device body 101 to achieve the opening and closing of the box door 102. Compared with directly installing the pulley 104 on the device body 101, installing the pulley 104 on the hinge fixing member 109 only requires the modification of the hinge fixing member 109, which is smaller in size and easier to process. Compared with directly connecting the telescopic component 105 to the box door 102, connecting the telescopic component 105 to the hinge 108 only requires the modification of the hinge 108, which is smaller in size and easier to process, and can reduce the presence of the elastic pull rope 103 connected to the telescopic component 105, so that the appearance is more beautiful.
[0045] In an optional solution of this embodiment, the telescopic assembly 105 includes a first connecting member 124 and a second connecting member 125, wherein the first connecting member 124 is connected to the end of the elastic pull rope 103, and the second connecting member 125 is connected to the hinge 108. One of the first connecting member 124 and the second connecting member 125 is provided with a guide groove 126, and the other is provided with a guide member 127, and the guide member 127 can reciprocate in the guide groove 126. The guide groove 126 can limit the range of motion of the guide member 127, so that the telescopic assembly 105 can be extended or shortened within a preset range, and by controlling the size of the telescopic range of the telescopic assembly 105, the size of the gap formed between the box door 102 and the device body 101 can be controlled accordingly.
[0046] In the optional solution of this embodiment, Figure 3 As shown, the first connecting member 124 is provided with two guide grooves 126, and the notches of the two guide grooves 126 are oriented in opposite directions. The second connecting member 125 is correspondingly provided with two guide members 127 arranged at intervals, and the ends of the two guide members 127 are provided with a positioning protrusion 128, and the protruding directions of the two positioning protrusions 128 are oriented in opposite directions. The first connecting member 124 is provided with a plug interface, and the plug interface is connected with the two guide grooves 126. The guide member 127 has a slight elasticity. When the first connecting member 124 and the second connecting member 125 are assembled, the two guide members 127 can be slightly brought together so that the two guide members 127 can be inserted into the first connecting member 124 from the plug interface and extend into the corresponding guide groove 126. The positioning protrusion 128 can extend from the notch of the corresponding guide groove 126 and can slide back and forth along the length direction of the corresponding guide groove 126.
[0047] In an optional solution of this embodiment, the door pull rope structure also includes a reset component; the reset component is configured to apply a reset force to the telescopic component 105 so that the telescopic component 105 has a tendency to shorten.
[0048] In this embodiment, when the door 102 is closed, the elastic cord 103 is retracted. If the telescopic assembly 105 is in an extended state, the elastic cord 103 will be loose and cannot be tightly wound around the pulley 104, which may easily cause the elastic cord 103 to be detached from the pulley 104. The present application provides a reset assembly, which can apply a reset force to the telescopic assembly 105 when the door 102 is closed, so that the telescopic assembly 105 is shortened to the shortest length.
[0049] Specifically, the reset component may include the following two solutions:
[0050] Option 1: See Figure 2 and Figure 3 As shown, the reset assembly includes a return spring 117 (return elastic member), a first connecting ear 118 and a second connecting ear 119. The first connecting ear 118 is connected to the first connecting member 124, and the second connecting ear 119 is connected to the second connecting member 125. One end of the return spring 117 is hooked on the first connecting ear 118, and the other end of the return spring 117 is hooked on the second connecting ear 119. When the door 102 is opened, the telescopic assembly 105 is stretched to stretch the return spring 117; when the door 102 is closed, under the pulling force of the return spring 117, the distance between the first connecting member 124 and the second connecting member 125 is close.
[0051] Option 2: See Figure 4 and Figure 5 As shown, the reset component includes a first magnetic member and a second magnetic member. The first magnetic member can be specifically a magnet 120. The first connecting member 124 is provided with a magnet fixing portion 121, and the magnet 120 can be installed on the magnet fixing portion 121 by a screw. The second magnetic member can be a metal member 122. In order to facilitate installation, the second magnetic member can be set as a screw, and the second connecting member 125 is provided with a screw fixing portion 123, and the screw is threadedly connected to the screw fixing portion 123. The positions of the magnet 120 and the screw can also be interchanged. When the box door 102 is opened, the telescopic component 105 is stretched to disengage the first magnetic member from the second magnetic member; when the box door 102 is closed, under the action of the magnetic attraction force of the first magnetic member and the second magnetic member, the distance between the first connecting member 124 and the second connecting member 125 is close.
[0052] Embodiment 2
[0053] The door pull rope structure in the second embodiment is an improvement on the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.
[0054] In an optional solution of this embodiment, the elastic pull rope 103 includes a pull rope 113 and a door elastic member 114. The pull rope 113 is wound around the pulley 104 to drive the pulley 104 to rotate. Specifically, the pulley 104 includes a rotating shaft 110 and a wheel body 111, the wheel body 111 is rotatably mounted on the rotating shaft 110, and the wheel body 111 is provided with a groove, and the pull rope 113 can be wound around the wheel body 111 and embedded in the groove, so that the pull rope 113 is not easy to be separated from the wheel body 111.
[0055] More specifically, one end of the pull rope 113 is connected to the telescopic assembly 105, and the other end of the pull rope 113 is connected to the door elastic member 114. The end of the door elastic member 114 away from the pull rope 113 is connected to the preset end of the hinge fixing member 109, and the preset end is the end of the hinge fixing member 109 away from the hinge point. Preferably, the preset end is provided with a plurality of hooking positions 116, and the end of the door elastic member 114 away from the pull rope 113 is hooked at any hooking position 116.
[0056] In this embodiment, the sliding door elastic member 114 is specifically a spring, and hooks are provided at both ends of the spring. The hook at one end of the spring is connected to the hinge fixing member 109 installed on the device body 101, and does not affect the structure of the device body 101. The hook at the other end of the spring is connected to the pull rope 113, and the surface of the pull rope 113 is smooth. It is wound in the groove of the pulley 104 to make the movement of the elastic pull rope 103 smoother.
[0057] Furthermore, the end of the spring away from the pull rope 113 is connected to the end of the hinge fixing member 109 away from the hinge point, so that a longer spring has enough space to accommodate it, and a longer spring can adapt to a larger swing angle of the door 102. A plurality of hooking positions 116 are provided at the preset end, and the spring can be hooked at any hooking position 116 according to the elasticity of the spring. By adjusting the hooking position 116, the angle between the door 102 and the device body 101 can be adjusted when it falls freely, and the pull rope 113 can be kept in a straightened state to prevent the pull rope 113 from being separated from the pulley 104.
