Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Examples:

as shown in fig. 1 to 9, the overflow assembly provided in this embodiment includes an overflow pipe 1 and a cap 2; one end of the overflow pipeline 1 is an overflow end, and the overflow end of the overflow pipeline 1 is provided with an overflow notch 10; the cap 2 is covered on the overflow end of the overflow pipe 1 and covers the overflow notch 10.

As shown in fig. 1, 7 and 9, the overflow assembly provided in this embodiment may be applied to an appliance such as a dishwasher having an inner container 3 and capable of injecting liquid in the inner container 3, and in order to prevent the appliance from accumulating liquid and overflowing to the outside due to abnormal conditions such as a malfunction of a water inlet valve, the appliance is generally used together with a foam float, a micro switch 7 and a drain pump. At this time, the overflow end of the overflow pipe 1 in the overflow assembly provided by the embodiment can be arranged in the inner container 3 of the appliance, the other end of the overflow pipe 1 can be communicated with the space where the foam float is located, when the appliance accumulates liquid due to abnormal conditions, the liquid can enter the space where the foam float is located through the overflow pipe 1, so that the foam float floats and touches the micro switch 7, and then the micro switch 7 can be linked with the main control board of the appliance to start the drainage pump, so that redundant liquid in the inner container 3 of the appliance is discharged to the outside, and the liquid cannot overflow out of the inner container 3.

Since the liquid entering the inner container 3 of the dish washer and other appliances is in a spray shape when the dish washer and other appliances perform normal washing operation, the liquid cannot be accumulated in the inner container 3 of the appliances, but the liquid can still contact the overflow end of the overflow pipeline 1. As shown in fig. 2, 3 and 4, in the overflow assembly provided in this embodiment, the overflow end cover of the overflow pipe 1 is provided with the cap 2, so that the cap 2 shields the overflow end, so that the liquid entering the liner 3 needs to bypass the edge of the cap 2 and then enter the gap between the cap 2 and the overflow pipe 1, then reaches the overflow notch 10 of the pipe wall of the overflow pipe 1 along the gap, and then enters the overflow pipe 1 through the overflow notch 10, so that the cap 2 can effectively prevent the liquid directly entering the overflow pipe 1, thereby effectively preventing the liquid sprayed above the overflow end from directly entering the overflow pipe 1, and preventing appliances such as a dish washer from being mistakenly used for water leakage abnormality and mistakenly starting the drain pump.

When the liquid is accumulated in the inner container 3 of the appliance due to an abnormal condition, the accumulated liquid can bypass the edge of the cap 2 and enter the gap between the cap 2 and the overflow pipe 1, and can enter the overflow pipe 1 through the gap and the overflow notch 10, so that the appliances such as a dish washer can automatically start the drain pump to automatically drain water, and at the moment, the water overflow preventing function of the appliances cannot be affected by the cap 2.

Compared with the prior art, the overflow assembly provided by the embodiment is characterized in that the cover cap 2 is arranged at the overflow end of the overflow pipeline 1, so that liquid in the dish washer needs to bypass the edge of the cover cap 2 and then enter a gap between the cover cap 2 and the overflow pipeline 1, then the liquid can enter the overflow pipeline 1 through the overflow notch 10, the cover cap 2 blocks the process that the liquid enters the overflow pipeline 1, and liquid splashed during normal washing operation of the dish washer can be effectively prevented from directly entering the overflow pipeline 1 through the overflow end, so that false alarm of water leakage of the dish washer is prevented.

In practical application, the cap 2 may be in a groove shape, and at this time, the cap 2 may be fixed outside the overflow end of the overflow pipe 1 in a fastening manner. Alternatively, the inner wall of the cap 2 may be provided with an internal thread, and the pipe wall of the overflow pipe 1 may be provided with an external thread at a position close to the overflow end, and at this time, the cap 2 may be screwed to the outside of the overflow end of the overflow pipe 1 by the internal thread and the external thread.

In the present embodiment, as shown in fig. 4, 5 and 6, a clamping structure 4 is provided between the cap 2 and the overflow pipe 1, and the clamping structure 4 includes a clamping protrusion 40 and a clamping hole 41; one of the clamping protrusion 40 and the clamping hole 41 is arranged on the cover cap 2, the other is arranged on the overflow pipe 1, and the clamping protrusion 40 is clamped in the clamping hole 41.

Compared with the connection mode that the cap 2 is directly buckled outside the overflow end, the clamping structure 4 can improve the connection stability between the cap 2 and the overflow pipeline 1, so that the cap 2 is prevented from automatically falling off at the overflow end of the overflow pipeline 1.

Compared with the connection mode of the cap 2 outside the overflow end through the threaded connection, the clamping structure 4 can improve the mounting and dismounting convenience between the cap 2 and the overflow pipeline 1, and due to the existence of the overflow notch 10, the installation stability of the cap 2 is difficult to ensure by the threaded connection mode, so that the clamping structure 4 can effectively ensure the installation stability of the cap 2 outside the overflow end, and the clamping structure 4 is preferably arranged between the cap 2 and the overflow pipeline 1.

Further, as shown in fig. 4, 5 and 6, the locking protrusion 40 is provided on the inner wall of the cap 2, and the locking hole 41 is provided on the pipe wall of the overflow pipe 1.

The clamping structures 4 may be multiple groups, and the multiple groups of clamping structures 4 are distributed between the cap 2 and the overflow pipe 1 along the circumferential direction of the overflow pipe 1 at intervals.

The multiunit joint structure 4 that distributes along the circumference interval of overflow pipe 1 not only can effectively promote the connection stability between block 2 and the overflow pipe 1, and can promote the connection equilibrium between block 2 and the overflow pipe 1.

In the present embodiment, there is a space between the inner peripheral wall of the cap 2 and the outer tube wall of the overflow tube 1 in the radial direction of the overflow tube 1.

The interval enables the liquid stored in the inner container 3 of the dish washer and other appliances to smoothly enter the gap between the cover cap 2 and the overflow pipeline 1, so that the drainage pump equipped with the appliance is started in time to timely drain the stored liquid.

Further, as shown in fig. 8, along the circumferential direction of the overflow pipe 1, the pipe wall of the overflow pipe 1 adjacent to the overflow notch 10 is a supporting portion 11; as shown in fig. 4 and 6, the inner wall of the end surface of the cap 2 facing the overflow end is provided with a stopper 20, and the stopper 20 abuts against one side of the supporting portion 11.

The limiting piece 20 is used for being matched with the supporting part 11 of the overflow pipeline 1, so that the connection stability between the cap 2 and the overflow pipeline 1 is improved, and a guiding effect can be achieved on the process that the cap 2 is covered outside the overflow end.

It should be noted that, since the limiting member 20 abuts against one side of the supporting portion 11, the limiting member 20 does not block the overflow notch 10, and at this time, the liquid may pass through the edge of the cap 2 and then enter the space between the inner wall of the cap 2 and the limiting member 20, and enter the space between the inner wall of the cap 2 and the outer wall of the overflow pipe 1, and then may enter the overflow pipe 1 through the overflow notch 10 on one side of the limiting member 20.

When the pipe wall of the overflow pipe 1 adjacent to the overflow notch 10 is the supporting portion 11, the clamping hole 41 may be disposed at the supporting portion 11 of the overflow pipe 1.

Further, the limiting member 20 is an arc-shaped plate, and the arc-shaped plate extends along the circumferential direction of the overflow pipe 1.

When the limiting piece 20 is an arc-shaped plate, the fitting degree between the limiting piece 20 and the outer wall of the overflow pipeline 1 can be effectively improved, and therefore the installation stability between the limiting piece 20 and the overflow pipeline 1 is effectively improved.

As shown in fig. 8, the overflow notch 10 is a plurality of overflow notches 10, and the plurality of overflow notches 10 are distributed at intervals along the circumferential direction of the overflow pipe 1, so that the pipe wall of the overflow pipe 1 forms a plurality of supporting parts 11 distributed at intervals along the circumferential direction; alternatively, as shown in fig. 6, the number of stoppers 20 is plural, and the plurality of stoppers 20 are in contact with the plurality of support portions 11 in one-to-one correspondence. Or, the overflow notch 10 and the limiting piece 20 are multiple, the multiple overflow notches 10 are distributed at intervals along the circumferential direction of the overflow pipe 1, and the multiple limiting pieces 20 are in one-to-one corresponding abutting connection with the multiple supporting portions 11.

The overflow notches 10 enable liquid in the gap between the cap 2 and the overflow pipeline 1 to easily enter the overflow pipeline 1, so that the response speed of the overflow preventing function of the dish washer and other appliances can be improved, the liquid in the inner container 3 of the appliance can be discharged in time, and loss of the appliance caused by overflow to a user is avoided.

As shown in fig. 1, 3 and 5, the overflow assembly provided in this embodiment further includes a water softener 5, the overflow pipe 1 is disposed in the water softener 5, and two ends of the overflow pipe 1 are respectively communicated with the outside.

The water softener 5 is used for purifying tap water so that water entering the inner container 3 of a dish washer and the like is soft water. Because when appliances such as dish washer are equipped with water softener 5 and overflow structure, water softener 5 and overflow structure all set up in the foam float place space of utensil generally, consequently water softener 5 can occupy the usage space of utensil, locate water softener 5 with overflow pipe 1 in this moment, can integrate overflow pipe 1 in an organic whole with water softener 5 to effectively practice thrift the space of utensil that is equipped with the foam float, make the space of utensil that is equipped with the foam float obtain make full use of, need not increase the whole volume of utensil.

As shown in fig. 2, in order to prevent the liquid in the overflow pipe 1 from entering the inside of the water softener 5 to damage the water softener 5, a sealing ring 50 is installed between the inner wall of the water softener 5 and the outer wall of the overflow pipe 1.

As shown in fig. 7, the overflow assembly provided in this embodiment further includes a support base 6 having an overflow cavity 60 formed therein; the end part of the overflow pipeline 1, which is far away from the overflow end, is arranged in the overflow cavity 60 of the supporting seat body 6, and the overflow end extends out of the top of the overflow cavity 60; alternatively, the water blocking member 30 is provided on the peripheral side of the top of the supporting base 6, and the overflow end is lower than the top of the water blocking member 30. Or, the end of the overflow pipe 1 far away from the overflow end is arranged in the overflow cavity 60 of the supporting seat body 6, the overflow end extends out of the top of the overflow cavity 60, the water retaining member 30 is arranged on the periphery of the top of the supporting seat body 6, and the overflow end is lower than the top of the water retaining member 30.

The overflow cavity 60 of the supporting seat 6 is used for accommodating an overflow structure equipped with a dish washer and other appliances, and correspondingly, the end of the overflow pipeline 1 far away from the overflow end is arranged in the overflow cavity 60 of the supporting seat 6.

In order to facilitate the smooth flow of the liquid in the inner container 3 of the appliance into the overflow cavity 60 through the overflow pipe 1, the supporting seat 6 is usually arranged below the inner container 3 of the appliance, and the water blocking member 30 on the top circumference side of the supporting seat 6 can be formed by the circumferential side wall of the inner container 3 assembly of the appliance.

The water blocking device 30 is used for blocking the liquid with the liquid level lower than that of the water blocking device 30 inside the liner 3 from flowing out to the outside. Since the drain pump equipped with the dish washer and other appliances can be started after a period of time when the appliances overflow, the water blocking device 30 is preferably arranged on the periphery of the top of the supporting seat body 6 and the overflow end is lower than the top of the water blocking device 30, at this time, the water blocking device 30 can block the liquid in the inner container 3 from overflowing to the outside before the drain pump is started, and when the liquid level in the inner container 3 reaches the top of the water blocking device 30, the drain pump is started, and the liquid in the inner container 3 is discharged.

It can be seen that the water blocking member 30 can prevent the liquid in the inner container 3 from overflowing to the outside before the drainage pump is started, so that the water blocking member can be matched with the drainage pump, and the liquid in the whole process of accumulating the liquid in the device can not overflow to the outside.

As shown in fig. 9, the overflow assembly provided in this embodiment further includes a micro switch 7 and a float structure 8, where the micro switch 7 and the float structure 8 are both disposed in the overflow cavity 60, and the float structure 8 is disposed below the micro switch 7 at intervals, and the float structure 8 is configured to float upward to trigger the micro switch 7 when liquid enters the overflow cavity 60.

The float structure 8 can be a foam float, and after the liquid enters the overflow cavity 60, the float structure 8 can rise under the action of the buoyancy of the liquid, so that the thrust is applied to the micro switch 7 above the float structure to trigger the micro switch 7.

The micro switch 7 is used for sending an alarm signal after being triggered to remind a user that the appliance is provided with a drain pump, and the drain pump and the micro switch 7 can also be linked through a main control board of the appliance to automatically start the drain pump to drain the liquid stored in the liner 3 when the micro switch 7 is triggered.

Wherein, the float bracket 9 covered outside the float structure 8 can also play a limiting role on the float structure 8 in the floating process, so that the float structure 8 after floating can accurately trigger the micro switch 7.

It should be noted that, to prevent the float support 9 from obstructing the process of triggering the micro switch 7 by the float structure 8, the micro switch 7 may be fixed to the side of the float support 9 facing the float structure 8. Alternatively, the float support 9 may be provided with a through hole, the micro switch 7 being fixed to the side of the float support 9 facing away from the float structure 8, but the triggered position of the micro switch 7 and the through hole in the float support 9 facing each other, in which case the float structure 8 may contact and trigger the micro switch 7 through the through hole.

As shown in fig. 9 and 10, the inner side of the bottom of the support base 6 is provided with a diversion trench 61, and the float structure 8 is located in the diversion trench 61.

The diversion trench 61 is used for guiding the liquid in the overflow cavity 60 to flow to the float structure 8, so that the float structure 8 can float up in time when the liquid enters the overflow cavity 60.

The embodiment also provides a dish-washing machine comprising the overflow assembly. Because dish washer includes above-mentioned overflow subassembly, consequently dish washer and above-mentioned overflow subassembly that this embodiment provided can solve the same technical problem, reach the same technical effect, and is not repeated here.
