In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0039] Reference below Figure 1-Figure 9 A dishwasher 100 according to an embodiment of the present application is described. The dishwasher 100 is an automatic cleaning device that can be used to clean tableware, such as bowls, chopsticks, plates and other tableware.

[0040] The dishwasher 100 according to the present application includes an inner tank 1, an overflow water receiving shell 3 and a bottom plate assembly 2. The inner tank 1 is used to form a cleaning chamber 10. Tableware to be cleaned can be arranged in the cleaning chamber 10, and an overflow port 111 is provided at the bottom plate 11 of the inner tank 1. When the water level in the cleaning chamber 10 reaches a preset height, the water in the inner tank 1 can be discharged through the overflow port 111.

[0041] Reference Figure 1 The chassis assembly 2 is arranged below the inner tank 1, and the chassis assembly 2 includes: a chassis 21 and a baffle 22. The overflow detection device 4 is mounted on the chassis 21, and the baffle 22 is mounted on the chassis 22. The baffle 22 is provided with a guide groove, one end of which is used to connect to the overflow water receiving shell 3, and the other end of which is connected to the chassis 21. The guide groove can guide water into the chassis 21.

[0042] It can be understood that the chassis assembly 2 includes two parts, the chassis 21 and the baffle 22. The chassis 21 is a mounting carrier for the overflow detection device 4. The baffle 22 is used to dock with the overflow water receiving shell 3 and further guide the water to the chassis 21. When the amount of water in the chassis 21 reaches a preset amount, the overflow detection device 4 can be triggered, thereby determining that the inner tank 1 in the dishwasher 100 is at a high water level.

[0043] The overflow detection device 4 is used to detect whether the dishwasher 100 overflows, so as to improve the safety of the dishwasher 100. It is understandable that when there is too much water in the inner tank 1, the dishwasher 100 will overflow. For example, when the dishwasher 100 has abnormal drainage, the water in the cleaning cavity 10 cannot be discharged in time, resulting in too high a water level in the cleaning cavity 10; when the dishwasher 100 has too much water inflow, the water level in the cleaning cavity 10 is high.

[0044] Reference Figure 1The overflow water collecting shell 3 is installed on the chassis assembly 2, and the overflow water collecting shell 3 can receive the water flowing out through the overflow port 111, and further guide the water to the side of the chassis 21 through the baffle 22, so as to guide the water overflowing from the inner tank 1 to the chassis 21, so as to detect the overflow problem of the dishwasher 100 through the overflow detection device 4.

[0045] It should be noted that, in the related art, dishwashers usually adopt a high water level alarm method, which is equipped with a high water level pressure switch. The high water level pressure switch converts the water pressure into an electrical signal for monitoring, so that when the water level in the inner cavity of the dishwasher reaches a preset height, it is determined that the water level in the dishwasher has reached a high water level and an alarm is issued to remind the user. As a result, the water level detection of the dishwasher is affected by the accuracy of the water level pressure switch, and the determination of the inner cavity water level has a large deviation.

[0046] In the present application, an overflow port 111 is provided at the inner tank 1, through which excess water in the inner tank 1 can be discharged, and further guided to the baffle 22 through the overflow water receiving shell 3, and the water is directed to the chassis 21 through the baffle 22, so as to be detected by the overflow detection device 4 at the chassis assembly 2. If the amount of water flowing into the chassis assembly 2 can trigger the overflow detection device 4, it means that the water level in the inner tank 1 reaches the preset high water level, thereby achieving the purpose of high water level protection. Compared with the prior art, there is no need to set a pressure switch, and there is no need to reserve a wiring structure on the inner tank 1 or the body.

[0047] It should be noted that the water level in the cleaning chamber 10 is monitored by the overflow detection device 4 arranged in the chassis assembly 2. If the high water level is reached in the dishwasher 100, the water in the inner tank 1 can be discharged to the chassis assembly 2 through the overflow port 111 via the overflow water receiving shell 3. When the amount of water flowing into the chassis assembly 2 is able to trigger the overflow detection device 4, it can be determined that the water level in the dishwasher 100 has reached the high water level, and it is necessary to stop injecting water into the inner tank 1 or to drain the water in the inner tank 1 in time.

[0048] like Figure 6 and Figure 7 As shown, in some embodiments of the present application, the overflow water receiving shell 3 includes: a bottom wall 31 and a side wall 32 .

[0049] Further integration Figure 3 and Figure 4 The bottom wall 31 is arranged below the overflow port 111, and the bottom wall 31 is used to connect with the overflow port 111 in the vertical direction. The side wall 32 is connected to the bottom wall 31, and the side wall 32 extends from the bottom wall 31 to one side of the inner tank 1 to form a water receiving groove 301. The water flowing out through the overflow port 111 can flow into the water receiving groove 301 and be further guided to one side of the chassis assembly 2 through the bottom wall 31.

[0050] It can be understood that the water receiving groove 301 has a water receiving space, so that a buffer structure is formed at the overflow water receiving shell 3, and part of the overflow water can be accumulated through the overflow water receiving shell 3, and the water is guided to one side of the chassis assembly 2 under the action of the bottom wall 31. At the same time, the side wall 32 can prevent the water received by the overflow water receiving shell 3 from dripping from the side, and the water receiving effect of the overflow water receiving shell 3 can be ensured.

[0051] In some embodiments of the present application, the upper edge of at least part of the side wall 32 (such as the front side wall of the overflow water receiving shell 3) is not lower than the overflow port 111, so that part of the side wall 32 in the overflow water receiving shell 3 is arranged opposite to the overflow port 111 to prevent the water flow from being too large and unable to flow into the water receiving tank 301. When water overflows from the overflow port, the water has an inertia to flow outward. By arranging the side wall 32 and the overflow port 111 opposite to each other, the water at the overflow port 111 can be prevented from splashing, thereby ensuring the overflow water receiving shell 3 to receive the water flowing out of the overflow port 111.

[0052] Reference Figure 1 The overflow port 111 is formed on the front side of the dishwasher 100, and the corresponding overflow water receiving shell 3 can also be installed to the chassis assembly 2 from the front side of the dishwasher 100, and the side wall 32 located at the front of the overflow water receiving shell 3 is arranged opposite to the overflow port 111, and the side wall 32 on the front side of the overflow water receiving shell 3 is arranged higher than the overflow port 111, thereby improving the docking effect between the overflow water receiving shell 3 and the overflow port 111, and can fully receive the water flowing out through the overflow port 111.

[0053] like Figure 1 As shown, in some embodiments of the present application, the bottom plate 11 of the inner tank 1 is provided with two overflow ports 111 , and the two overflow ports 111 are respectively arranged near the two ends of the bottom plate 11 in the left and right directions, thereby ensuring the discharge effect of water in the inner tank 1 through the overflow ports 111 .

[0054] Reference Figure 1 The “left-right direction” is also the width direction of the dishwasher 100. When two overflow ports 111 are respectively provided on both sides of the bottom plate 11 in the width direction, the overflow effect at the overflow ports 111 can be ensured even if the dishwasher 100 tilts. For example, when the dishwasher 100 tilts to the left or right, the overflow port 111 located on the tilted side of the bottom plate 11 also has an overflow effect, so that the water in the inner tank 1 can be discharged to the overflow water receiving shell 3 through the overflow port 111.

[0055] In a further embodiment of the present application, when two overflow ports that are far apart are formed on the bottom plate 11, two overflow water receiving shells 3 may be provided, and the two overflow water receiving shells 3 correspond to the two overflow ports 111, respectively, so as to guide the water to the side of the chassis assembly 2 through two diversions, thereby eliminating the need to construct the overflow water receiving shell 3 as a larger diversion structure.

[0056] like Figure 6 and Figure 7 As shown, in some embodiments of the present application, the overflow water receiving shell 3 is provided with a retaining rib 33, which is arranged on the bottom wall 31 and located on the inner side of the side wall 32, and the retaining rib 33 is used to guide the water in the water receiving trough 301 to one side of the chassis assembly 2 to ensure the water diversion effect of the overflow water receiving shell 3 on water.

[0057] Reference Figure 6 and Figure 7 There are two retaining ribs 33, and a water flow channel is defined between the two retaining ribs 33. The water in the water receiving trough 301 flows to the outlet side of the water receiving trough 301 under the action of the two retaining ribs 33. The retaining ribs 33 are raised upward from the bottom wall 31, which can improve the structural strength of the bottom wall 31 while guiding the water.

[0058] Combination Figure 3 and Figure 5 In some embodiments of the present application, the bottom wall 31 extends obliquely downward from the side docking with the overflow port 111 to the side docking with the chassis assembly 2, thereby improving the water guiding effect of the overflow water receiving shell 3. It can be understood that after the overflow water receiving shell 3 receives the water discharged from the overflow port 111, the water will flow toward the lower side (i.e., the end of the bottom wall 31 docking with the chassis assembly 2) along the extension direction of the bottom wall 31 under the action of gravity, so as to guide the water to the chassis assembly 2.

[0059] In some embodiments of the present application, the inner tank 1 is provided with a slot, and the side wall 32 is provided with a plug-in portion 35, and the plug-in portion 35 is used to plug and cooperate with the slot, so as to connect the overflow water collecting shell 3 with the inner tank 1, and the overflow water collecting shell 3 is installed by plugging, and the installation method is simple and reliable.

[0060] Reference Figure 5 , the plug-in portion 35 can be constructed as a guide structure 351 or a snap-in structure 352. When the plug-in portion 35 is constructed as a guide structure 351, it can play an auxiliary guiding role in the plug-in installation of the overflow water receiving shell 3, thereby reducing the difficulty of assembling the overflow water receiving shell 3 and the inner liner 1; when the plug-in portion 35 is constructed as a snap-in structure 352 (such as a hook, etc.), the overflow water receiving shell 3 and the inner liner 1 can be snap-fitted and fixed by the snap-in structure 352, thereby improving the connection reliability between the overflow water receiving shell 3 and the inner liner 1. Of course, a plurality of plug-in portions 35 can be formed on the side wall 32. For example, two plug-in portions 35 are formed on the side wall 32, one of which is constructed as a guide structure 351, and the other is constructed as a snap-in structure 352. The overflow water receiving shell 3 can be connected to the inner liner 1 through the guide structure 351 and the snap-in structure 352.

[0061] like Figure 8 and Fig. 9As shown, in some embodiments of the present application, the baffle 22 includes: a first plate body 221 and a second plate body 222. The first plate body 221 is disposed below the overflow water receiving shell 3 in the horizontal direction, and the first plate body 221 is used to dock with the overflow water receiving shell 3, so as to receive the water transported by the overflow water receiving shell 3 through the first plate body 221, and the second plate body 222 is disposed vertically and connected to the first plate body 221, and the second plate body 222 is used to dock with the bottom plate 21, so as to further guide the water to the bottom plate 21 side. The guide groove extends from the first plate body 221 to the second plate body 222.

[0062] It is understandable that the cooperation between the first plate 221 and the second plate 222 has a good guiding effect on the water flow, thereby preventing the water flow from splashing. Among them, the dishwasher 100 also includes an electric control box, which is usually arranged in the installation space formed between the chassis assembly 2 and the inner tank 1. If the water at the chassis assembly 2 splashes, there is a risk of water droplets splashing to the electrical connection port, which poses a safety hazard. In the present application, the water flow is guided by the baffle 22, and the water flow can be smoothly guided to the chassis 21 to prevent water droplets from splashing.

[0063] like Figure 8 and Fig. 9 In a further embodiment of the present application, the guide groove includes a first guide section 223 and a second guide section 224 that are connected, the first guide section 223 is formed on the first plate body 221, the second guide section 224 is formed on the second plate body 222, and the first guide section 223 can guide water to the side of the second guide section 224. Thus, the water flow path on the baffle 22 is defined by the guide groove.

[0064] Among them, the first guide section 223 is used to dock with the overflow water receiving shell 3, the water discharged through the overflow water receiving shell 3 can flow to the first guide section 223, and the water in the first guide section 223 can flow to the second guide section 224, and the second guide section 224 can further guide the water flow to the bottom plate 21.

[0065] Reference Figure 4 In the chassis assembly 2, the first plate 221 is arranged horizontally (also in the width direction of the dishwasher 100), so that the first guide section 223 opened upward is formed on the first plate 221 to ensure the docking effect between the first guide section 223 and the overflow water receiving shell 3; the second plate 222 is arranged vertically, and the second guide section 224 formed on the second plate 222 also extends vertically, and the water flowing into the second guide section 224 through the first guide section 223 can flow downward along the extension direction of the second guide section 224 to the chassis 21. In this way, the water flow can flow along the preset path, preventing the water flow from running wildly and flowing to other parts of the dishwasher 100, and ensuring the guiding effect of the baffle 22 on the water flow.

[0066] like Figure 8 As shown, in some embodiments of the present application, a first water retaining rib 225 is provided in the first guide section 223, and the first water retaining rib 225 is used to slow down the water flow speed to prevent the water flow from overflowing the outside of the guide groove due to excessive flow speed.

[0067] Reference Figure 5 The first water retaining rib 225 protrudes upward from the bottom wall 31 of the first guide section 223 to block the water flow through the first water retaining rib 225, thereby slowing down the water flow rate, preventing the water flow from splashing due to excessively fast water flow, and ensuring that the water flow can smoothly flow into the second guide section 224.

[0068] The first water retaining rib 225 is located downstream of the position where the first flow guide section 223 is connected to the overflow water receiving shell 3, and the first water retaining rib 225 is arranged perpendicular to the flow direction of the first flow guide section 223. For example, the extension direction of the first water retaining rib 225 in the first flow guide section 223 is arranged perpendicular to the flow direction of the water in the first flow guide section 223, and is also the normal angle of the flow direction of the water, so that the first water retaining rib 225 can ensure the blocking effect of the water flow to fully slow down the water flow speed. Figure 5 Preferably, the first water retaining rib 225 is arranged near the connection point between the first guide section 223 and the second guide section 224, so as to slow down the flow rate of water flowing to the connection point between the first guide section 223 and the second guide section 224 through the first water retaining rib 225, thereby preventing water from splashing from the first guide section 223 into the chassis 21.

[0069] like Figure 8 and Fig. 9 As shown, in some embodiments of the present application, a water baffle 226 is provided on the second plate body 222, and the water baffle 226 is arranged near the transition between the first guide section 223 and the second guide section 224, and the water baffle 226 is arranged in the downstream area of ​​the guide groove to prevent water splashing in the downstream area of ​​the guide groove.

[0070] In some embodiments of the present application, the water baffle 226 is connected to two oppositely disposed side walls of the second guide section 224, and the water baffle 226 at least partially covers the side of the second guide section 224 open to the bottom plate 21 to prevent water flow in the second guide section 224 from splashing.

[0071] The second guide section 224 extends on the second plate body 222 in the vertical direction and is open inwardly, and the water retaining plate 226 is disposed near the corner of the first plate body 221 and the second plate body 222 .

[0072] It can be understood that at the transition between the first guide section 223 and the second guide section 224, the flow direction of the water flow changes from lateral flow to vertical downward flow. The water baffle 226 can prevent the water flow from directly rushing out of the baffle 22 and splashing onto other devices in the chassis 21 when the flow rate is too fast, thereby improving the safety of the dishwasher 100.

[0073] like Figure 8 and Fig. 9 As shown, in some embodiments of the present application, a second water retaining rib 227 is provided in the guide groove, the second water retaining rib 227 is arranged at the front edge of the baffle 22, and the second water retaining rib 227 is located below the connection between the overflow water receiving shell 3 and the baffle 22, and the second water retaining rib 227 can block at least part of the gap between the overflow water receiving shell 3 and the bottom wall of the first guide section 223 to prevent water in the first guide section 223 from overflowing outward through the gap between the overflow water receiving shell 3 and the first guide section 223.

[0074] When the second water retaining rib 227 completely blocks the gap between the overflow water receiving shell 3 and the bottom wall of the first guide section 223 , the second water retaining rib 227 can also abut against the lower surface of the overflow water receiving shell 3 to support the overflow water receiving shell 3 through the second water retaining rib 227 .

[0075] The second water retaining rib 227 protrudes upward from the bottom wall 31 of the first guide section 223 to prevent excessive water from flowing from the overflow water receiving shell 3 to the first guide section 223 and causing the overflow water to flow to the outside of the baffle 22 .

[0076] Reference Figure 8 and Fig. 9 The second water retaining ribs 227 are multiple in number, and the multiple second water retaining ribs 227 are arranged at intervals on the baffle plate 22, and can be arranged at an angle to the front edge of the baffle plate 22, thereby increasing the difficulty of water flowing out from the front side of the first guide section 223 to prevent water from overflowing. At the same time, it can also facilitate the backflow of water flowing to the second water retaining ribs 227.

[0077] Reference Figure 8 and Fig. 9 In a specific embodiment, there are three second water retaining ribs 227, wherein two second water retaining ribs 227 are arranged at intervals in the width direction of the first flow guide section 223 to increase the water retaining width of the second water retaining ribs 227 and improve the water retaining effect. A shielding structure extending in a gradually expanding shape toward the front side of the baffle 22 is formed between the two transversely arranged second water retaining ribs 227 to increase the difficulty of water in the first flow guide section 223 flowing out to the front side and facilitate the backflow of overflowed water.

[0083] It can be understood that by setting a third guide section 2232 in the first guide groove 201 that connects the first guide section 223 and the second guide section 224, the lateral position of the second guide section 224 in the baffle 22 can be adjusted so as to arrange the second guide section 224 in an area suitable for avoiding components in the installation space of the chassis assembly 2.

[0084] Furthermore, the second guide groove 202 includes a first guide section 223 and a second guide section 224 which are connected in sequence, the first guide section 223 is arranged along the width direction of the first plate body 221 , and the second guide section 224 is arranged along the width direction of the second plate body 22 .

[0085] like Figure 5 As shown, in some embodiments of the present application, the baffle 22 is provided with a limiting flange 228, which is formed at the front edge of the baffle 22 and folded upward. The overflow water receiving shell 3 is provided with a limiting protrusion 34, and the limiting flange 228 is used to cooperate with the limiting protrusion 34 to prevent the overflow water receiving shell 3 from falling out. The limiting protrusion 34 is set on the side wall 32 of the overflow water receiving shell 3.

[0086] Combination Figure 1 and Figure 5After the overflow water receiving shell 3 is installed from the outside to the inside of the inner tank 1 by plugging, the overflow water receiving shell 3 can be limited by the limiting protrusion 34 and the limiting flange 228 to prevent the overflow water receiving shell 3 from falling out of the installation area, thereby improving the assembly reliability of the overflow water receiving shell 3.

[0087] In some embodiments of the present application, a guide surface is formed on the chassis 21, and the guide surface is used to guide the water flow to one side of the overflow detection device 4, so that the water flow in the chassis 21 can quickly converge at the overflow detection device 4, thereby improving the detection effect of the overflow detection device 4.

[0088] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the claims and their equivalents.
