Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a dishwasher. Background Art

[0002] Automatic door opening technology is the development trend of existing dishwasher technology. A dishwasher with automatic door opening function can use a door panel without handles. It realizes the door opening function through automatic door opening technology, which improves the appearance and intelligence of the dishwasher. In addition, the automatic door opening technology can also be applied to the dishwasher after the washing process is completed, automatically opening the door for drying to reduce the energy consumption of the dishwasher.

[0003] The automatic door opening technology in the prior art is usually implemented in the following two ways: 1. After the door is unlocked, it opens under the action of gravity, and a hovering module is set to control the opening angle of the door. However, in this implementation, the preset angle of the door opening controlled by the hovering module cannot be adjusted. Especially for doors of different weights, the opening angles vary greatly, which is inconvenient for users to open the door smoothly or the user may be easily injured if the opening angle is too large; 2. The ejector continuously ejects the door, and the angle of the door hovering is controlled by the ejection length of the ejector. However, this implementation requires the ejector to have a large thrust, and it is difficult to achieve a fast ejection speed of the ejector under the prior art, so it generally requires a relatively long waiting time.

[0033] See also Figure 1 , Figure 1 The structural schematic diagram of a dishwasher 100 in an embodiment of the present application is shown. An embodiment of the present application provides a dishwasher 100, which includes a main body 110, a door body 120 and a door lock 150. The door body 120 is rotatably connected to the main body 110, and the door body 120 includes an open state and a closed state. The door lock includes a clamping assembly 152 and a lock catch. The clamping assembly 152 is provided on the main body 110, and the lock catch 151 is fixedly connected to the door body 120. When the door body 120 is in the closed state, the door lock 150 can lock the door body 120 by locking the lock catch 151. The lock catch 151 is movably provided relative to the clamping assembly 152, and can be clamped or disengaged by the clamping assembly 152. In the process of the lock catch 151 disengaging from the clamping assembly 152, the clamping assembly 152 has a force to drive the lock catch 151 to disengage to drive the door body 120 to open.

[0034] like Figure 8 As shown, the lock buckle 151 is provided with inclined surfaces of two clamping jaws which are arranged back to back and respectively face the clamping assembly 152. During the process of the lock buckle being disengaged, the two clamping jaws respectively act on the two inclined surfaces and have a force to drive the lock buckle to be disengaged, thereby providing a thrust to drive the door body 120 to open.

[0035] like Figure 1 As shown, the main body 110 includes an inner liner 112 and a base 113 located below the inner liner 112 , wherein the inner liner 112 is provided with a cleaning chamber 111 with an open front end, and the door body 120 is rotatably connected to the bottom end of the side wall of the inner liner 112 and covers the cleaning chamber 111 .

[0036] like Figure 1 As shown, the dishwasher 100 further includes a suspension assembly 130, which includes a tensioning member 131, a positioning block 132 fixedly disposed on the tensioning member 131, and a limiting member 133 disposed on the main body 110. Specifically, the limiting member 133 is connected to the base 113. Figure 2 As shown, both ends of the tensioning member 131 are respectively connected to the main body 110 and the door body 120 , and the door body 120 includes a hanging portion 122 for connecting the tensioning member 131 , one end of the tensioning member 131 is connected to the hanging portion 122 , and the other end is connected to the base 113 .

[0037] like Figure 1 In the illustrated embodiment, the suspension assembly 130 further includes an elastic member 137, which is connected between the main body 110 and the tension member 131, that is, one end of the elastic member 137 is connected to the base 113, and the other end is connected to the tension member 131, and one end of the tension member 131 away from the elastic member 137 is connected to the hanging portion 122 of the door body 120. The tension member 131 is configured such that when the door body 120 is in an open state, the door body 120 drives the tension member 131 to be tightened, so that the elastic member 137 is stretched to provide a reaction force when the door body 120 is opened, thereby realizing the suspension of the door body 120.

[0038] like Figure 2 and Figure 3 As shown, in one embodiment, the limit member 133 is used to prevent the positioning block 132 from moving toward the elastic member 137 under the elastic force of the elastic member 137, and the tensioning member 131 includes a tightening section 1311 and a slack section 1312. The slack section 1312 is formed between the positioning block 132 and the end of the tensioning member 131 connected to the door body 120, and the tightening section 1311 is formed between the positioning block 132 and the end of the tensioning member 131 connected to the main body 110. When the door body 120 is in a closed state, the slack section 1312 is in a relaxed state and under the action of the positioning block 132 and the limit member 133, the tightening section 1311 is in a tensioned state. When the door body 120 is in an open state, the slack section 1312 is tightened, and at this time, the slack section 1312 and the tightening section 1311 are both in a tensioned state.

[0039] like Figure 2 and Figure 5 As shown, in one embodiment, the suspension assembly 130 further includes a tensioning wheel 136, and the tensioning wheel 136 acts on the tensioning section 1311 to keep the tensioning section 1311 in a tensioned state.

[0040] Combination Figure 3 As shown, the limit member 133 is locked to the main body 110 after being adjusted along the moving direction of the positioning block 132, so that the relative position of the limit member 133 and the main body 110 can be adjusted, that is, the movement of the positioning block 132 can be adjusted, thereby adjusting the length of the slack section 1312, and then adapting to door bodies 120 of different weights or different opening preset angles of the door bodies 120.

[0041] like Figure 3 and Figure 5As shown, in one embodiment, the suspension assembly 130 also includes a fastener 134, the limit member 133 is provided with a mounting groove 1333 extending along the moving direction of the positioning block 132, the fastener 134 passes through the mounting groove 1333 and is detachably connected to the main body 110, and the fastener 134 can be connected to the main body 110 at any position within the mounting groove 1333 to achieve the position adjustment of the limit block relative to the main body 110.

[0042] like Figure 5 As shown, in one embodiment, the stopper 133 includes a connecting surface 1331 and an abutting surface 1332 arranged at an angle, the positioning block 132 abuts against the abutting surface 1332, and the mounting groove 1333 is provided on the connecting surface 1331. In this embodiment, the abutting surface 1332 is arranged perpendicular to the connecting surface 1331. It can be understood that the abutting surface 1332 is provided with a through hole for the tensioning member 131 to pass through, so that the positioning block 132 can abut against the abutting surface 1332.

[0043] Combination Figure 5 As shown, when the door body 120 is in a closed state, the positioning block 132 abuts against the limiting member 133, and when the door body 120 is in an open state, combined with Figure 1 As shown, during the process of the door body 120 rotating from a closed state to an open state, the hanging portion rotates with the door body 120 and drives the tensioning member 131 connected to one end of the door body 120 to move synchronously. At this time, the tensioning member 131 is tightened and transmits the elastic force of the stretched elastic member 137 to the door body 120, so that the tensioning member 131 has a tendency to drive the positioning block 132 away from the limiting member 133.

[0044] like Figure 2 and Figure 5 As shown, in one embodiment, the hovering assembly 130 also includes a guide wheel 135, which is connected to the base 113 of the main body 110, and an abutment groove 1351 is recessed on the outer peripheral surface of the guide wheel 135. When the slack section 1312 is in a tensioned state, it partially abuts against the abutment groove 1351, so as to limit the guide wheel 135 through the abutment groove 1351 to prevent the tensioning member 131 from escaping from the position restriction of the guide wheel 135.

[0045] like Figure 2 refer to Figure 4 As shown, the main body 110 includes an anti-slip block 1131 protruding from the end surface provided with the guide wheel 135, and the protruding height of the anti-slip block 1131 is not less than the distance between the abutment groove 1351 and the end surface to prevent the loose section 1312 in a loose state from slipping out of the abutment groove 1351.

[0046] like Figure 3 and Figure 4As shown, in one embodiment, the anti-slip block 1131 is located below the guide wheel 135, and the distance between the end face of the anti-slip block 1131 facing the guide wheel 135 and the outer circumferential surface of the guide wheel 135 in the radial direction of the guide wheel 135 is L, and the diameter of the tensioning member 131 is d, L>d, which can facilitate the placement of the tensioning member 131 into the abutment groove 1351 for easy assembly. Exemplarily, in this embodiment, the tensioning member 131 is a soft steel wire rope, which can be slightly bent under the action of external force to be assembled into the abutment groove 1351. The distance between the end surface of the anti-drop block 1131 facing the guide wheel 135 and the outer circumference of the guide wheel 135 in the vertical direction is l, d>l, so as to prevent the slack section 1312 in a relaxed state from slipping out of the abutment groove 1351. The tensioning member 131 is restricted by the position of the anti-drop block 1131 in a relaxed state and does not bend too much, and is in a horizontal state or a large-angle bent state. When it is tightened again, it can still remain in the abutment groove 1351. Figure 4 As shown, in this embodiment, the number of the anti-dropping blocks 1131 is 2, and the two anti-dropping blocks 1131 are arranged at intervals.

[0047] In one embodiment, the tensioning member 131 is non-detachably connected to the door body 120 to prevent the tensioning member 131 from being separated from the door body 120 , thereby improving the reliability of the hovering assembly 130 .

[0048] like Figure 5 As shown, in the embodiment provided in the present application, the hanging portion 122 is provided with a hanging groove 123 with an opening, the tensioning member 131 is hung in the hanging groove 123, and the door body 120 also includes an anti-slipping member 124 provided on the hanging portion 122 and covering part of the opening, and the length of the opening not covered by the anti-slipping member 124 is not greater than the diameter of the tensioning member 131, so as to prevent the tensioning member 131 hung in the hanging groove 123 from slipping out of the opening. The anti-slipping member 124 is non-detachably connected to the hanging portion 122. In other embodiments, the tensioning member 131 and the hanging portion 122 can also be set as an integral structure. For example, the tensioning member 131 and the hanging portion 122 are integrally formed.

[0049] like Figure 6 As shown, in one embodiment, the dishwasher 100 includes a buffer assembly 140, which acts on the door body 120 and provides a force in the opposite direction to the moving direction of the door body 120 relative to the inner tank 112, slowing down the instantaneous speed of the ejector rod when the door lock 150 is unlocked, thereby improving the user experience. Moreover, when the door is not opened actively by the user, that is, the door lock 150 is unlocked automatically due to a fault, but the ejector rod of the door lock 150 is not ejected, the reverse force provided by the buffer assembly 140 can be used to keep the door body 120 in a closed but unlocked state, thereby preventing the door body 120 from opening and causing injuries to the user.

[0050] like Figure 6As shown, the inner tank 112 is provided with a cleaning chamber 111, combined with Figure 7 As shown, when the door body 120 is in a closed state, the door body 120 is at least partially embedded in the cleaning chamber 111, and the door body 120 includes at least one friction peripheral wall 121 embedded in the cleaning chamber 111 and opposite to the inner wall of the cleaning chamber 111, and the buffer component 140 is arranged on the friction peripheral wall 121 and / or the inner wall of the cleaning chamber 111 opposite to the friction peripheral wall 121. When the door body 120 is in a closed state, the buffer component 140 is squeezed between the friction peripheral wall 121 and the inner wall of the cleaning chamber 111 opposite to the friction peripheral wall 121 to increase the friction between the two, thereby providing a force in the opposite direction to the movement direction of the door body 120 relative to the inner tank 112.

[0051] In one embodiment, the buffer assembly 140 is protruded from the top wall and / or the side wall of the cleaning chamber 111. Figure 6 and Figure 7 FIG. 1 shows a schematic diagram of a buffer assembly 140 protruding from the top wall of the cleaning chamber 111, and as shown in FIG. Figure 7 As shown, when the door body 120 is in a closed state, the buffer assembly 140 is in interference fit with the door body 120 to increase the friction between the door body 120 and the top wall of the cleaning chamber 111, thereby providing a force in the opposite direction to the movement direction of the door body 120 relative to the inner tank 112. In other embodiments, the buffer assembly 140 may also be provided on the friction peripheral wall 121 of the door body 120, such as the top wall and / or the side wall. When the door body 120 is in a closed state, the buffer assembly 140 is in interference fit with the inner wall of the cleaning chamber 111 opposite to the friction peripheral wall 121, so as to increase the friction between the door body 120 and the top wall of the cleaning chamber 111, thereby providing a force in the opposite direction to the movement direction of the door body 120 relative to the inner tank 112.

[0052] In this embodiment, the buffer assembly 140 includes a flexible member 142 and a fastening screw 141. The flexible member 142 can be deformed when subjected to force. The fastening screw 141 is used to fix the flexible member 142 to the top wall of the cleaning chamber 111. In this embodiment, the flexible member 142 is soft rubber.

[0053] In the dishwasher 100 provided in the above scheme, during the process of opening the door body 120, the clamping assembly 152 of the door lock 150 drives the lock buckle 151 to disengage to apply a door-opening torque to the door body 120. In the initial stage of opening, the door body 120 needs to overcome the friction torque of the buffer assembly 140. After that, the door body 120 falls due to gravity, and the hovering assembly 130 positions the opening angle of the door body 120 and controls the door body 120 to hover at a preset angle.

[0054] The dishwasher 100 provided in the above scheme is configured with a limit member 133 in the suspension assembly 130 that can be adjusted along the moving direction of the positioning block 132 and then locked to the main body 110, so that the relative position of the limit member 133 and the main body 110 can be adjusted, that is, the position of the positioning block 132 can be adjusted, and then the length of the tension member 131 that can be switched to a relaxed state is adjusted. The length of the relaxed section 1312 in the tension member 131 is related to the idle stroke length in the suspension assembly 130 and is also related to the preset opening angle of the door body 120, so that the position of the limit member 133 is adjusted when assembling the limit member 133, thereby adjusting the preset opening angle of the door body 120, and then corresponding to different opening angles of the door body 120 of different weights, thereby achieving both the door opening efficiency provided by the lock body for automatic door opening and the adjustable and flexible door opening angle.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
