[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] Dishwasher inner tubs typically require water intake via external pipes and need to connect to external components. There's a possibility of leaks at these connections, leading to potential leakage during use. Under gravity, the leaked liquid will drip onto the base, where electrical appliances are located. While some technologies aim to isolate these appliances from the dripping liquid, the water may still splash onto the base, potentially causing an electric shock.

[0036] To resolve the above technical issues, please refer to [link / reference]. Figure 1 This application provides a dishwasher for cleaning tableware. The dishwasher includes an inner tub 200, a base assembly 100, and a shell. The base assembly 100 is located below the inner tub 200 and connected to the inner tub 200 to support the inner tub 200.

[0037] The inner liner 200 may have a square structure, and the internal space of the inner liner 200 may be formed as a washing chamber 200a. The inner liner 200 may be made of metal, thereby giving it better strength; of course, the inner liner 200 may also be made of plastic, and this application does not limit this.

[0038] The washing chamber 200a serves as the main cleaning space of the dishwasher and has a spray arm inside. Water is supplied to the spray arm through a pipe outside the washing chamber 200a, so there is a possibility of leakage at the connection between the pipe and the inner tank 200.

[0039] The outer shell is the external protective layer of the dishwasher, which can protect the internal components of the dishwasher from damage by the external environment. In order to increase the stability of the overall structure, the inner tub 200 is connected to the outer shell. The specific connection method may be riveting. Therefore, there is a possibility of leakage at the riveting point.

[0040] The base assembly 100 is located below the inner tank 200 and connected to the inner tank 200 to support the inner tank 200. The base assembly 100 can be equipped with a high-efficiency water pump and filter to form a closed water circulation system and realize the reuse of water resources.

[0041] Water seeping from the inner liner 200 (i.e., leakage) will drip downwards along the inner liner 200 under the influence of gravity, forming a dripping point at the bottom of the inner liner 200. The leakage will then drip downwards through this dripping point. (See the implementation details in this application.) Figure 2 as well as Figure 3 The base 110 includes a base body 111 and a water-blocking structure 120.

[0042] The base body 111 is connected to the inner liner 200 and can support the entire inner liner 200.

[0043] The water-blocking structure 120 is located above and connected to the base 110. The water-blocking structure 120 has a water-receiving groove 120a. When the inner liner 200 is placed on the base 110, the water-receiving groove 120a is located below the dripping position. The water-receiving groove 120a receives the leaking liquid flowing out of the dripping position, and the side wall of the water-receiving groove 120a can reduce the probability of splashed water coming into contact with electrical appliances, thereby reducing the probability of electric shock accidents.

[0044] Please see Figure 3 In one embodiment of this application, the base 110 includes a base body 111 and a support structure 112.

[0045] The base body 111 is connected to the inner liner 200 and can support the entire inner liner 200.

[0046] The support structure 112 is located above the base body 111 and connected to the base body 111. Thus, the support structure 112 can increase the structural strength of the entire base 110. The support structure 112 can be integrally formed with the base body 111, or it can be a separate structure connected together. When the support structure 112 and the base body 111 are integrally formed, the structural strength of the entire base 110 can be further improved. When the support structure 112 and the base body 111 are separate structures, the support structure 112 can be flexibly installed according to the dripping level of the inner liner 200.

[0047] The water-blocking structure 120 is located above the base structure 112 and connected to the base structure 112. It is understood that since the base structure 112 is located above the base body 111 and has a height difference with the base body 111, when the water-blocking structure 120 is located above the base structure 112, that is, the water-blocking structure 120 is relatively closer to the dripping position of the inner tank 200. Therefore, the range of water droplets splashed by the leakage dripping from the dripping position is reduced, and it is easier to be blocked by the water-blocking structure 120, thereby reducing the possibility of leakage coming into contact with electrical appliances.

[0048] In some embodiments, the water-retaining structure 120 can be integrally formed with the pier structure 112, thereby improving the structural strength of the pier structure 112. In another embodiment, the water-retaining structure 120 and the pier structure 112 are separate structures connected to each other. The separate structure design allows the water-retaining structure 120 and the pier structure 112 to be manufactured and replaced independently. If one component is damaged or needs to be upgraded, only that component needs to be replaced, without replacing the entire structure, thereby reducing maintenance costs. In addition, the separate structure design allows the water-retaining structure 120 and the pier structure 112 to be customized and adjusted according to different needs and scenarios.

[0049] Based on the emphasis on the strength of the base 110 structure in this embodiment, the water-blocking structure 120, the support structure 112, and the base body 111 are designed as a single piece.

[0050] Please see Figure 2 as well as Figure 3 In one embodiment of this application, the support structure 112 is located on the side of the base body 111. In this way, the base body 111 has enough space to install structures such as motors, water pumps and filters, and it is also convenient to connect wires. On the other hand, the support structure 112 is located on the side of the base body 111, which can also play a certain role in preventing water overflow.

[0051] It should be understood that the inner tank 200 may include a top plate 210, two side shells 220, a back plate 230, and a bottom plate 240. The top plate 210 and the bottom plate 240 are arranged opposite each other in the height direction of the machine body. The two side shells 220 and the back plate 230 are connected between the top plate 210 and the bottom plate 240. The two side shells 220 are arranged opposite each other in the width direction of the machine body. The back plate 230 is connected between the two side shells 220. Thus, a washing cavity 200a with an opening can be formed between the top plate 210, the two side shells 220, the back plate 230, and the bottom plate 240. The dishwasher also includes a door, which is arranged opposite to the back plate 230 and located on the front side of the inner tank 200. The door is rotatably mounted on the inner tank 200 to open and close the washing cavity 200a.

[0052] The applicant discovered that the leakage trend of the inner liner 200 is mainly due to the liquid dripping along the side shell 220. That is, the dripping point is not a single dripping point, but a collection of multiple dripping points. At the same time, in order to consider the miniaturization of the entire base 110 structure, some electrical components are installed on the surface of the support structure 112. In order to further reduce costs, in this embodiment of the application, the water-blocking structure 120 is located near the electrical components on the surface of the support structure 112. In this way, the leakage dripping near the electrical components can fall into the water receiving tank 120a, and the splashed water droplets can be blocked by the baffle structure, making it difficult for them to come into contact with the electrical components, thus reducing the occurrence of electric shock accidents.

[0053] Because the water-blocking structure 120 is located near electrical installations on the surface of the pier structure 112, leaking liquid from the dripping point may fall directly outside the water receiving tank 120a. Therefore, in this embodiment, please refer to... Figure 3 The surface of the pier structure 112 has a first drainage groove 112a, and the base body 111 has a water collection groove 111a. The first drainage groove 112a connects the water receiving groove 120a and the water collection groove 111a, and the first drainage groove 112a is located above the water collection groove 111a.

[0054] In this way, the leaking liquid dripping from the receiving position can fall into the water receiving tank 120a and the first drainage tank 112a, and the water receiving tank 120a can be connected to the first drainage tank 112a, and the first drainage tank 112a can also be connected to the water collection tank 111a. Thus, the leaking liquid that falls into the first drainage tank 112a and the water receiving tank 120a can eventually flow into the water collection tank 111a of the base body 111 under the action of gravity, which is convenient for centralized discharge and thus avoids the occurrence of water accumulation.

[0055] Based on the previous embodiment, please refer back to the previous document. Figure 1 From the edge of the water collection tank 111a to the middle of the water collection tank 111a, the depth of the water collection tank 111a gradually increases, and the middle of the water collection tank 111a is used to place the liquid level alarm.

[0056] The design of the water collection tank 111a, with shallow edge grooves and deep middle grooves, allows water to more easily collect from the edge when it flows into the water collection tank 111a and gradually flow to the deeper middle area. The leakage in the first drainage groove 112a can quickly flow into the water collection tank 111a, effectively utilizing the volume of the water collection tank 111a and thus improving drainage efficiency.

[0057] In addition, since the edge of the water collection tank 111a is a smooth transition, the leakage liquid can flow slowly when entering the water collection tank 111a, avoiding water from splashing too fast and coming into contact with electrical components on the base plate 240, thereby reducing the occurrence of electric shock accidents.

[0058] Placing a level alarm in the center of the water collection tank 111a ensures that the alarm is located in the core area where water converges, thus enabling more accurate monitoring of water level changes. When the water level reaches the preset alarm threshold, the level alarm can promptly send a signal to the controller, which can then control the dishwasher to pause operation, allowing the user to easily check the cause of the leak.

[0059] In addition, an electronic valve is installed in the drainage pipe, and the liquid level alarm can be connected to the electronic valve signal. For example, when the liquid level alarm detects that the water level has reached the preset height, it can open the electronic valve to complete the automatic drainage.

[0060] Please see Figure 3 In some embodiments of this application, the support structure 112 includes a plurality of supports arranged in a stepped manner. The support with the highest height along the vertical direction is close to the side of the base 110, and the support with the lowest height along the vertical direction forms a first drainage groove 112a.

[0061] Since the dripping point is a collection of multiple dripping locations, multiple support platforms are set up in a stepped manner, that is, there is a height difference between two adjacent support platforms. In this way, under the action of gravity, the leaking liquid dripping onto the support platform structure 112 can quickly flow through each support platform into the first drainage trough 112a, and finally collect in the water collection trough 111a at the bottom.

[0062] The number of support platforms is not limited. For example, only one support platform, two support platforms, three support platforms, or four support platforms can be set. The specific number can be set according to the actual situation. In this embodiment, three support platforms are set. Vertically, the heights from low to high are defined as the first support platform 1121, the second support platform 1122, and the third support platform 1123. Therefore, electrical appliances can be set on the first support platform 1121, the second support platform 1122, or the third support platform 1123 according to actual installation requirements. Electrical appliances can also be set on two or three support platforms at the same time. This embodiment of the application describes the example of an electrical appliance being set on one of the support platforms.

[0063] When the electrical appliance is installed on the first support 1121, the water-blocking structure 120 is installed on the upper surface of the first support 1121, and the first drainage channel 112a is installed on the upper surface of the first support 1121. When the electrical appliance is installed on the second support 1122, the water-blocking structure 120 is installed on the upper surface of the second support 1122, and the first drainage channel 112a is installed on the upper surface of the first support 1121. No specific restrictions are imposed on this.

[0064] With the electrical appliance mounted on the first support platform 1121, a water-blocking structure 120 is provided on the upper surface of the first support platform 1121, and the vertical plate connecting the first support platform 1121 and the second support platform 1122 forms the side wall of the water receiving tank 120a. In this way, not only can material costs be saved, but when the liquid flows from the surface of the second support platform 1122 to the vicinity of the electrical appliance on the surface of the first support platform 1121, it can also fall directly into the water receiving tank 120a, preventing the liquid leaking from the second support platform 1122 to the surface of the first support platform 1121 from splashing and contacting the electrical appliance, thereby improving the safety of the electrical appliance.

[0065] Based on the previous embodiment, see [link / reference] Figure 3 The upper surface of the highest vertical support has an inner circumference plate 1123a and an outer circumference plate 1123b. Compared with the inner circumference plate 1123a, the outer circumference plate 1123b is closer to the side of the base 110. The inner circumference plate 1123a and the outer circumference plate 1123b form a third drainage groove 112b.

[0066] When the support structure 112 includes three supports, the support with the highest vertical height is the third support 1123. The projection of the dripping point on the base 110 is located on the side of the outer plate 1123b facing the inner plate 1123a. That is, the leaking liquid dripping from the dripping point can fall onto the first support 1121, the second support 1122, and the third support 1123. Under the obstruction of the outer plate 1123b, the leaking liquid dripping from the dripping point is difficult to drip outside the base 110, thereby reducing the probability of bacterial growth.

[0067] The inner circumference plate 1123a may have a notch so that water from the third drainage trough 112b can flow through the notch to the surface of the second support 1122. The number of notches may be multiple. The notches can guide the leakage liquid to flow along a preset trajectory, which can avoid contact with electrical appliances and optimize the layout of the entire base 110, making the electrical appliances on the base 110 more compact.

[0068] It is understandable that a notch is also provided on the first drainage trough 112a, so that the leakage in the first drainage trough 112a can also flow into the water collection trough 111a according to the preset trajectory. It should be understood that, considering that there are many components on the base 110, a drainage channel can also be provided between the first drainage trough 112a and the water collection trough 111a, so as to be staggered from the electrical appliances and facilitate a more compact layout of the components on the base 110.

[0069] Please see Figure 3 In some embodiments of this application, the water receiving trough 120a can be provided as one or more. When there is only one water receiving trough 120a, the water blocking structure 120 can include multiple plate-shaped members, which together form the water receiving trough 120a. This reduces material costs.

[0070] When there are multiple water receiving tanks 120a, the water blocking structure 120 includes multiple first baffles 121. The multiple first baffles 121 are distributed at intervals along the first direction XX. Two adjacent first baffles 121 form a water receiving tank 120a. By controlling the distance between two adjacent first baffles 121, the leakage liquid entering the water receiving tank 120a can be effectively blocked by the first baffles 121 when it splashes up, thereby reducing the possibility of splashed water droplets coming into contact with electrical appliances.

[0071] Furthermore, the multiple first baffles 121 can be integrally formed with the water-blocking structure 120, thereby increasing the stability of the water-blocking structure 120.

[0072] It should be understood that when multiple first baffles 121 are distributed at intervals along the first direction XX, the electrical appliances adjacent to the water-blocking structure 120 on the base 110 should be located at both ends of the water-blocking structure 120 along the first direction XX. In this way, when the leaking liquid splashes up in the water receiving tank 120a, it can be blocked by the first baffles 121 and is unlikely to come into contact with the electrical appliances. Furthermore, ribs should be provided around the electrical appliances to prevent the leaking liquid from directly contacting the electrical appliances.

[0073] Furthermore, based on the previous embodiment, the first baffle 121 extends along the second direction YY, and along the second direction YY, a second baffle 122 is provided on the side of the first baffle 121 near the middle of the base 110. The second baffle 122 extends along the first direction XX, wherein the first direction XX, the second direction YY, and the vertical direction are perpendicular to each other.

[0074] When the door is located in front of the inner liner 200, the first direction XX can be relative to the front and back direction of the inner liner 200, and the second direction YY is the left and right direction of the inner liner 200. That is, through the setting of the first baffle 121 and the second baffle 122, it can prevent the leak from splashing towards the middle of the base 110 when it drips into the water receiving tank 120a, and reduce the possibility of the leak coming into contact with the motor and other electrical components in the middle of the base 110.

[0075] The first baffle 121 and the second baffle 122 can also be integrated. When the water-blocking structure 120 is located on the support structure 112, each water receiving tank 120a can be connected to the first drainage tank 112a to drain the leaked liquid in the water receiving tank 120a into the water collection tank 111a of the base body 111.
