Therefore, as the first positioning sleeve is arranged in one end of the spring in a penetrating manner, the second positioning sleeve is arranged in the other end of the spring in a penetrating manner, the positioning effect is achieved on the spring, and the stability of the plug in the pressing and moving process is better. In addition, when the water level exceeds standard, water enters the first positioning sleeve through the gap and the hollowed-out hole, and enters the third connecting part through the second positioning sleeve. In addition, the elastic piece is in direct connection with the connecting cover and in indirect connection with the overflow body.

In one embodiment, the bottom end of the plug is further provided with at least one guide post, the guide post is positioned outside the first positioning sleeve, the top surface of the connecting cover is further provided with a third positioning sleeve sleeved outside the second positioning sleeve, the third positioning sleeve is provided with a guide hole matched with the guide post in a guiding manner, and the guide post is movably arranged in the guide hole;

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

Referring to fig. 1 to 5, fig. 1 shows a schematic top view of a dishwasher base according to an embodiment of the present utility model. Fig. 2 shows an exploded view of the structure of fig. 1. Fig. 3 is a schematic diagram illustrating an operation state of the overflow protection device according to an embodiment of the utility model. Fig. 4 shows an enlarged schematic view of the structure of fig. 3 at a. Fig. 5 is a schematic view showing another operation state of the overflow protection assembly according to an embodiment of the present utility model. An embodiment of the present utility model provides an overflow protection assembly, including: the overflow body 10 and the closure assembly 20. The overflow body 10 is configured to be disposed on an inner wall of the liner, specifically, for example, on a liner bottom plate 30, the overflow body 10 is provided with a chamber 11, an overflow hole 12 communicating with the chamber 11 is disposed at a top of the overflow body 10, and a first connection portion 13 communicating with the chamber 11 is further disposed at a bottom of the overflow body 10. The first connection portion 13 is for connection with the overflow detection device 40. The plugging assembly 20 is disposed inside the chamber 11, and the plugging assembly 20 includes a plug 21 and an elastic member 22. The plug 21 is connected with the overflow body 10 through an elastic piece 22, the plug 21 is movably arranged in the overflow hole 12, and a gap is formed between the plug 21 and the wall of the overflow hole 12. The plug 21 is provided with a water receiving member 217, and the water receiving member 217 is configured to receive the liquid flowing in from the slit, and to overflow and discharge the liquid received by the water receiving member 217 to the first connecting portion 13 when the liquid reaches a predetermined amount.

In the above overflow protection assembly, when the water in the inner container of the dishwasher exceeds the set water level, as the gap is formed between the plug 21 and the wall of the overflow hole 12, the water flows into the chamber 11 through the gap and enters the water receiving member 217, the water receiving member 217 forces the plug 21 to compress the elastic member 22 under the gravity and the impact force of the water, so that the plug 21 descends (as shown in fig. 5), more water flows into the chamber 11 and enters the overflow detection device 40, after the float of the overflow detection device 40 floats, the micro switch is turned on, the signal is transmitted to the controller, and the controller correspondingly controls the drain pump to open for draining. When the water level of the liner is reduced below the overflow surface, the elastic member 22 is stressed to restore the position of the plug 21 (as shown in fig. 3 and 4). In addition, during normal washing of the dishwasher, the plug 21 is arranged in the overflow hole 12, so that water of the spray arm can be prevented from splashing into the chamber 11, dirt and foreign matters can be prevented from flowing into the chamber 11, and the false overflow phenomenon can be prevented.

Referring to fig. 2 to 5, in one embodiment, the distance between the top surface of the plug 21 and the bottom wall of the liner tends to decrease from the center position to the edge position, and the distance between the top surface of the overflow body 10 and the bottom wall of the liner tends to decrease from the center position to the edge position. When the elastic member 22 is in the stretched state, the top edge position 211 of the plug 21 is higher than or equal to the hole edge position 121 of the overflow hole 12 (as shown in fig. 3 and 4); when the elastic member 22 is in the contracted state, the top surface edge position 211 of the stopper 21 is lower than the hole edge position 121 of the overflow hole 12 (as shown in fig. 5). In this way, in the normal washing process of the dish washer, the elastic element 22 is in an extended state, the edge 211 of the top surface of the plug 21 is higher than or equal to the edge 121 of the overflow hole 12, the distance between the top surface of the plug 21 and the bottom wall of the liner is in a decreasing trend from the central position to the edge, and the distance between the top surface of the overflow body 10 and the bottom wall of the liner is in a decreasing trend from the central position to the edge, so that the liquid sputtered onto the top surface of the plug 21 can quickly flow back to the bottom of the liner along the top surface, and water can be better prevented from flowing into the water receiving element 217 through the gap. In addition, when the water in the inner container of the dishwasher exceeds the set water level, the gravity and the impact force of the water entering the water receiving member 217 force the plug 21 to compress the elastic member 22, so that the plug 21 descends, and the top edge position 211 of the plug 21 is lower than the hole edge position 121 of the overflow hole 12, so that more water flows into the water receiving member 217.

Referring to fig. 4, in some embodiments, the top surface of the plug 21 includes, but is not limited to, a conical surface, an arcuate surface, a beveled surface, a curved surface, etc., as long as the distance from the bottom wall of the liner is reduced from the center position to the edge position.

Referring to fig. 4, in some embodiments, the top surface of the overflow body 10 includes, but is not limited to, a conical surface, an arc surface, a straight surface, a curved surface, etc., as long as the distance from the bottom wall of the liner is reduced from the center position to the edge position.

Referring to fig. 4, in one embodiment, when the elastic member 22 is in the extended state, the top surface of the plug 21 and the top surface of the overflow body 10 are combined to form a conical surface, an arc surface or an inclined straight surface. In this way, during normal washing of the dishwasher, the liquid sprayed is guided such that most of the liquid flows back to the bottom of the inner container through the top surface, and less liquid enters the water receiving member 217 through the slit, so that the overflow detecting means 40 is not touched by mistake.

Referring to fig. 2 and 4, in one embodiment, the overflow protection device further includes a connection cover 50 disposed between the first connection portion 13 and the overflow detection device 40. The connection cover 50 is disposed outside the liner, and two opposite sides of the connection cover 50 are respectively provided with a second connection portion 51 and a third connection portion 52. The first connecting portion 13 is inserted into the mounting hole 31 of the bottom wall of the liner and connected to the second connecting portion 51, and the third connecting portion 52 is used for connecting to the overflow detecting device 40. In this way, in the assembly process, after the first connecting portion 13 is inserted into the mounting hole 31 of the bottom wall of the liner, the overflow protection assembly is quickly and firmly mounted on the liner by connecting the second connecting portion 51 with the first connecting portion 13.

Referring to fig. 2 and 4, in one embodiment, the second connecting portion 51 and/or the connecting cover 50 further abut against the bottom wall of the liner. In this way, the overflow body 10 is abutted against one side of the bottom wall of the liner, and the second connecting portion 51 and/or the connecting cover 50 are abutted against the other side of the inner wall of the liner, so that the overflow protection assembly is stably mounted on the liner.

The overflow body 10 is mutually abutted with the bottom wall of the inner container through the sealing ring 14, and the sealing ring 14 is arranged around the circumference of the mounting hole 31. Therefore, the sealing performance of the overflow protection assembly arranged on the bottom wall of the inner container can be improved.

In one embodiment, the third connection 52 is connected to the overflow detection device 40 by an overflow pipe 60.

In one embodiment, the first connection portion 13 is provided with a first thread and the second connection portion 51 is provided with a second thread adapted to the first thread. Thus, the disassembly and assembly operation of the overflow protection assembly can be conveniently realized.

Referring to fig. 2 and fig. 4, in one embodiment, the elastic member 22 is a spring, the bottom end of the plug 21 is provided with a first positioning sleeve 212, the plug 21 is further provided with a hollow hole 214 communicating the slit with the first positioning sleeve 212, and a water baffle 2172 circumferentially disposed around the hollow hole 214. Specifically, the height of the water deflector 2172 is lower than the notch of the water receiving groove 2171 such that the liquid received by the water receiving groove 2171 will overflow into the first positioning sleeve 212 through the water deflector 2172 and then enter into the third connecting portion 52 through the second positioning sleeve 54. The top surface of the connection cover 50 is provided with a second positioning sleeve 54 communicating with the third connection portion 52. The first positioning sleeve 212 is inserted into one end of the spring, and the second positioning sleeve 54 is inserted into the other end of the spring. Thus, since the first positioning sleeve 212 is inserted into one end of the spring, and the second positioning sleeve 54 is inserted into the other end of the spring, the positioning effect is achieved on the spring, and the stability of the plug 21 in the pressing and moving process is better. The elastic member 22 is in direct connection with the connection cover 50 and in indirect connection with the overflow body 10.

Referring to fig. 5, in one embodiment, the first positioning sleeve 212 is positioned opposite the second positioning sleeve 54. When the plug 21 is pushed down to the limit position, the bottom surface of the first positioning sleeve 212 and the top surface of the second positioning sleeve 54 are abutted against each other, the compression amount of the elastic member 22 is maximized, and the plug 21 is positioned at the lowest position.

Referring to fig. 2 and 4, in one embodiment, at least one guide post 215 is further disposed at the bottom end of the plug 21, the guide post 215 is located outside the first positioning sleeve 212, the top surface of the connection cover 50 is further provided with a third positioning sleeve 53 sleeved outside the second positioning sleeve 54, the third positioning sleeve 53 is provided with a guide hole 531 in guiding fit with the guide post 215, and the guide post 215 is movably disposed in the guide hole 531.

In one embodiment, the guide holes 531 are provided in two or more, the guide posts 215 are provided in two or more, and the two or more guide posts 215 are provided corresponding to the two or more guide holes 531.

Referring to fig. 2 and 4, in one embodiment, the plug 21 further includes a closure cap 216 coupled to the water receiving member 217. The overflow body 10 is provided with a flange 15 extending from the wall of the overflow hole 12 toward the inside of the chamber 11, and the water receiving member 217 is provided with a water receiving groove 2171. The flange 15 extends into the water receiving groove 2171. When the water in the inner container exceeds the liquid level and enters the chamber 11 through the gap, the water enters the water receiving groove 2171 along the flange 15, the flange 15 and the water receiving groove 2171 play a role in guiding and collecting the water, and the collected water finally enters the overflow detection device 40.

In one embodiment, the plugging cap 216 is coupled to the water receiving member 217, including but not limited to, by clamping, bonding, welding, riveting, or fastening using screws, pins, etc., and during the manufacturing process, care should be taken to ensure that a water leak hole or gap is maintained while the plugging cap 216 is coupled to the water receiving member 217. Thus, in the production process of the plug 21, the plug cap 216 and the water receiving member 217 are respectively manufactured and assembled together, so that the processing difficulty of the plug 21 can be reduced.

Referring to fig. 2 and fig. 4, in one embodiment, a buckle 2161 is provided at the bottom of the plugging cap 216, a hollow hole 214 corresponding to the buckle 2161 is provided on the water receiving member 217, and the buckle 2161 is clamped in the hollow hole 214.
