[0057] 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.

[0058] 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.

[0059] To solve the above technical problems, please refer to Figure 1. This application embodiment provides a dishwasher configured to clean tableware. The dishwasher includes an inner tub 1, a base assembly 20 and a shell. The base assembly 20 is located below the inner tub 1 and connected to the inner tub 1 to support the inner tub 1.

[0060] The inner liner 1 can be square in shape, and the internal space of the inner liner 1 can be formed as a washing chamber 100. The inner liner 1 can be made of metal, thereby giving it better strength; of course, the inner liner 1 can also be made of plastic, and this application does not limit it in this regard.

[0061] The washing chamber 100 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 100, so there is a possibility of leakage at the connection between the pipe and the inner tank 1.

[0062] 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 1 is connected to the outer shell. The specific connection method may be riveting. Therefore, there is a possibility of leakage at the riveting point.

[0063] The base assembly 20 is located below the inner liner 1 and is connected to the inner liner 1 to support the inner liner 1. The base assembly 20 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.

[0064] Water seeping out of the inner liner 1 (i.e. leakage) will drip down along the inner liner 1 under the action of gravity, forming a dripping position at the bottom of the inner liner 1. The leakage drips down through the dripping position. In this application, please refer to Figures 2 and 3. The base 2 includes a base body 21 and a water-blocking structure 202.

[0065] The base body 21 is connected to the inner liner 1 and can support the entire inner liner 1.

[0066] The water-blocking structure 202 is located above and connected to the base 2. The water-blocking structure 202 has a water-receiving groove 202A. When the inner liner 1 is placed on the base 2, the water-receiving groove 202A is located below the dripping position. The water-receiving groove 202A receives the leaking liquid flowing out of the dripping position, and the side wall of the water-receiving groove 202A can reduce the probability of splashed water coming into contact with electrical appliances, thereby reducing the probability of electric shock accidents.

[0067] Please refer to Figures 3 and 5. In one embodiment of this application, the base 2 includes a base body 21 and a side plate 22. The side plate 22 is connected to the periphery of the base body 21 and includes a support structure 221.

[0068] The base body 21 is connected to the inner liner 1 and can support the entire inner liner 1.

[0069] The support structure 221 is located above the base body 21 and connected to the base body 21. In this way, the support structure 221 can increase the structural strength of the entire base 2. The support structure 221 can be integrally formed with the base body 21, or it can be a separate structure connected together. When the support structure 221 and the base body 21 are integrally formed, the structural strength of the entire base 2 can be further improved. When the support structure 221 and the base body 21 are separate structures, the support structure 221 can be flexibly installed according to the dripping level of the inner liner 1.

[0070] The water-blocking structure 202 is located above the base structure 221 and connected to the base structure 221. It is understood that since the base structure 221 is located above the base body 21 and has a height difference with the base body 21, when the water-blocking structure 202 is located above the base structure 221, that is, the water-blocking structure 202 is relatively closer to the dripping position of the inner tank 1. 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 202, thereby reducing the possibility of leakage coming into contact with electrical appliances.

[0071] In some embodiments, the water-retaining structure 202 can be integrally formed with the pier structure 221, thereby improving the structural strength of the pier structure 221. In another embodiment, the water-retaining structure 202 and the pier structure 221 are separate structures connected to each other. The separate structure design allows the water-retaining structure 202 and the pier structure 221 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 202 and the pier structure 221 to be customized and adjusted according to different needs and scenarios.

[0072] Based on the emphasis on the strength of the base 2 structure in this embodiment, the water-blocking structure 202, the support structure 221 and the base body 21 are designed as a single piece.

[0073] Please refer to Figures 2 and 3. In one embodiment of this application, the support structure 221 is located on the side of the base body 21. In this way, the base body 21 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 221 is located on the side of the base body 21, which can also play a certain role in preventing water overflow.

[0074] It should be understood that the inner tank 1 may include a top plate 110, two side shells 120, a back plate 130, and a bottom plate 140. The top plate 110 and the bottom plate 140 are arranged opposite each other in the height direction of the machine body. The two side shells 120 and the back plate 130 are connected between the top plate 110 and the bottom plate 140. The two side shells 120 are arranged opposite each other in the width direction of the machine body. The back plate 130 is connected between the two side shells 120. Thus, the top plate 110, the two side shells 120, the back plate 130, and the bottom plate 140 can form a washing cavity 100 with an opening. The dishwasher also includes a door body, which is arranged opposite to the back plate 130 and located on the front side of the inner tank 1. The door body is rotatably mounted on the inner tank 1 to open and close the washing cavity 100.

[0075] The applicant discovered that the leakage trend of the inner liner 1 is mainly along the side shell 120, that is, the dripping position 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 2 structure, some electrical components will be installed on the surface of the support structure 221. In order to further reduce costs, in this embodiment of the application, the water-blocking structure 202 is located near the electrical components on the surface of the support structure 221. In this way, the leakage dripping near the electrical components can fall into the water receiving tank 202A, 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.

[0076] Because the water-blocking structure 202 is close to the electrical installations on the surface of the base structure 221, the leaking liquid dripping from the dripping point may fall directly outside the water receiving tank 202A. Therefore, in this embodiment of the application, please refer to Figures 3 and 6. A drainage groove 300 is formed on the surface of the base structure 221. The drainage groove 300 includes a first drainage groove 302 and a third drainage groove 301. A water collecting tank 200 is formed on the base body 21. The first drainage groove 302 connects the water receiving tank 202A and the water collecting tank 200, and the first drainage groove 302 is located above the water collecting tank 200.

[0077] In this way, the leaking liquid dripping from the receiving level can fall into the water receiving tank 202A and the first drainage tank 302, and the water receiving tank 202A can be connected to the first drainage tank 302, and the first drainage tank 302 can also be connected to the water collection tank 200. Thus, the leaking liquid falling into the first drainage tank 302 and the water receiving tank 202A can eventually flow into the water collection tank 200 of the base body 21 under the action of gravity, which is convenient for centralized discharge and thus avoids the occurrence of water accumulation.

[0078] Based on the previous embodiment, please refer back to Figure 1. From the edge of the water collection tank 200 to the middle of the water collection tank 200, the depth of the water collection tank 200 gradually increases, and the middle of the water collection tank 200 is configured to place the leakage detection device 3.

[0079] The design of the water collection tank 200, 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 200 and gradually flow to the deeper middle area. The leakage in the first drainage groove 302 can quickly flow into the water collection tank 200, effectively utilizing the volume of the water collection tank 200 and thus improving drainage efficiency.

[0080] In addition, since the edge of the water collection tank 200 is a smooth transition, the leakage liquid can flow slowly when entering the water collection tank 200, avoiding water from splashing too fast and coming into contact with electrical components on the base plate 140, thereby reducing the occurrence of electric shock accidents.

[0081] Placing the leak detection device 3 in the middle of the water collection tank 200 ensures that the alarm is located in the core area where the water flow converges, thus enabling more accurate monitoring of water level changes. When the water level reaches the preset alarm threshold, the leak detection device 3 can promptly send a signal to the controller, which will then control the dishwasher to pause operation, allowing the user to easily check the cause of the leak.

[0082] In addition, an electronic valve is installed in the drainage pipe. The leakage detection device 3 can be connected to the electronic valve signal. If the leakage detection device 3 detects that the water level has reached the preset height, it can open the electronic valve to complete the automatic drainage.

[0083] Please refer to Figure 3. In some embodiments of this application, the support structure 221 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 2, and the support with the lowest height along the vertical direction forms a first drainage groove 302.

[0084] 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 221 can quickly flow through each support platform into the first drainage trough 302, and finally collect in the water collection trough 200 at the bottom.

[0085] 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 2212, the second support platform 1122, and the third support platform 2211. Therefore, electrical appliances can be set on the first support platform 2212, the second support platform 1122, or the third support platform 2211 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.

[0086] When the electrical appliance is installed on the first support 2212, the water-blocking structure 202 is installed on the upper surface of the first support 2212, and the first drainage channel 302 is installed on the upper surface of the first support 2212. When the electrical appliance is installed on the second support 1122, the water-blocking structure 202 is installed on the upper surface of the second support 1122, and the first drainage channel 302 is installed on the upper surface of the first support 2212. No specific restrictions are imposed on this.

[0087] With the electrical appliance mounted on the first support platform 2212, a water-blocking structure 202 is provided on the upper surface of the first support platform 2212, and the vertical plate connecting the first support platform 2212 and the second support platform 1122 forms the side wall of the water receiving tank 202A. 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 2212, it can also fall directly into the water receiving tank 202A, preventing the liquid leaking from the second support platform 1122 to the surface of the first support platform 2212 from splashing and contacting the electrical appliance, thereby improving the safety of the electrical appliance.

[0088] Based on the previous embodiment, referring to Figure 3, the upper surface of the support platform with the highest vertical height has an inner circumference plate 2214 and an outer circumference plate 2213. Compared with the inner circumference plate 2214, the outer circumference plate 2213 is closer to the side of the base 2. The inner circumference plate 2214 and the outer circumference plate 2213 form a third drainage groove 301.

[0089] When the support structure 221 includes three supports, the support with the highest vertical height is the third support 2211. The projection of the dripping point on the base 2 is located on the side of the outer plate 2213 facing the inner plate 2214. That is, the leaking liquid dripping from the dripping point can fall onto the first support 2212, the second support 1122 and the third support 2211. Under the obstruction of the outer plate 2213, the leaking liquid dripping through the dripping point is difficult to drip outside the base 2, thereby reducing the probability of bacterial growth.

[0090] The inner circumference plate 2214 may have a notch so that water from the third drainage trough 301 can flow through the notch to the surface of the second base 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 also allows for the selection of the layout of the entire base 2, making the electrical appliance layout on the base 2 more compact.

[0091] It is understandable that a notch is also provided on the first drainage trough 302, so that the leakage in the first drainage trough 302 can also flow into the water collection trough 200 according to the preset trajectory. It should be understood that, considering that there are many components on the base 2, a diversion trough can also be set between the first drainage trough 302 and the water collection trough 200, so as to be staggered from the electrical appliances and make the component layout on the base 2 more compact.

[0092] Referring to Figure 3, in some embodiments of this application, there may be one or more water receiving channels 202A. When there is only one water receiving channel 202A, the water blocking structure 202 may include multiple plate-shaped members, which together form the water receiving channel 202A. This reduces material costs.

[0093] When there are multiple water receiving tanks 202A, the water blocking structure 202 includes multiple first baffles 2021. The multiple first baffles 2021 are distributed at intervals along the first direction XX. Two adjacent first baffles 2021 form a water receiving tank 202A. By controlling the distance between two adjacent first baffles 2021, the leakage liquid entering the water receiving tank 202A can be effectively blocked by the first baffles 2021 when it splashes up, thereby reducing the possibility of splashed water droplets coming into contact with electrical appliances.

[0094] In some embodiments, the plurality of first baffles 2021 can also be integrally formed with the water-blocking structure 202, thereby increasing the stability of the water-blocking structure 202.

[0095] It should be understood that when multiple first baffles 2021 are distributed at intervals along the first direction XX, the electrical appliances adjacent to the water-blocking structure 202 on the base 2 should be located at both ends of the water-blocking structure 202 along the first direction XX. In this way, when the leaking liquid splashes up in the water receiving tank 202A, it can be blocked by the first baffles 2021 and is unlikely to come into contact with the electrical appliances. Furthermore, ribs should be set around the electrical appliances to prevent the leaking liquid from directly contacting the electrical appliances.

[0096] In some embodiments, based on the previous embodiment, the first baffle 2021 extends along the second direction YY, and a second baffle 2022 is provided on the side of the first baffle 2021 near the middle of the base 2 along the second direction YY. The second baffle 2022 extends along the first direction XX, wherein the first direction XX, the second direction YY and the vertical direction are perpendicular to each other.

[0097] When the door is located in front of the inner liner 1, the first direction XX can be relative to the front and back direction of the inner liner 1, and the second direction YY is the left and right direction of the inner liner 1. That is, through the setting of the first baffle 2021 and the second baffle 2022, it can prevent the leak from splashing towards the middle of the base 2 when it drips into the water receiving tank 202A, and reduce the possibility of the leak coming into contact with the motor and other electrical components in the middle of the base 2.

[0098] The first baffle 2021 and the second baffle 2022 can also be set as one piece. When the water-blocking structure 202 is located on the support structure 221, each water receiving tank 202A can be connected to the first drainage tank 302 to drain the leakage liquid in the water receiving tank 202A into the water collection tank 200 of the base body 21.

[0099] Over long-term use, dishwashers are affected by various factors, such as frequent operation, prolonged temperature changes, and water flow impact within the inner tub. Over time, tiny gaps can develop at the joints, becoming channels for water leakage. Additionally, the inner tub wall contains connection holes for electrical components. During operation, the machine inevitably vibrates, which can alter the connections at these holes, causing them to loosen. Furthermore, the sealing material in these areas is constantly exposed to water, detergent, and temperature fluctuations, which can damage its sealing performance and lead to leakage.

[0100] When the inner tank leaks, the leaking water will flow down the outer wall of the inner tank. Since numerous electrical components are installed on the base, these water droplets, once in contact with these components, can cause a series of problems, such as short circuits or corrosion damage to the electrical components. These problems can seriously interfere with the normal operation of the dishwasher, reduce its lifespan, and may even lead to safety hazards, causing inconvenience and losses for the user.

[0101] Therefore, this application also provides a dishwasher that can quickly and effectively detect water leakage in the dishwasher's inner tank, thereby ensuring the normal operation of the dishwasher.

[0102] Specifically, referring to Figures 1, 4, and 5, the dishwasher in this embodiment includes a shell, an inner tub 1, a base 2, and a leakage detection device 3. The dishwasher shell is the external protective structure of the entire cleaning device, providing physical protection and support for the various components inside the dishwasher. The shell is typically made of materials with a certain strength and corrosion resistance, such as sheet metal or high-strength plastic. A door is connected to the front of the shell, and the door is connected to the shell by a suitable hinge or other connection method, allowing for easy opening and closing. Furthermore, the door may also be equipped with an operation panel for users to select washing programs, start or stop the dishwasher, etc.

[0103] The inner tank 1 is one of the core components of the dishwasher, installed inside the outer shell. The inner tank 1 has a washing chamber 100, the walls of which can be assembled by riveting the side walls to the top and bottom walls respectively. The opening of the washing chamber 100 faces the door. The shape and size of the washing chamber 100 can be determined according to the dishwasher's design capacity and the type of tableware. The inner tank 1 is generally made of materials with good high-temperature resistance and chemical stability, such as stainless steel. The washing chamber 100 is used to hold tableware and washing water. During the washing process, water within the chamber forms a high-pressure water jet through components such as spray arms, thoroughly rinsing the tableware. Electrical components, such as various sensors (water level sensor, temperature sensor, etc.), are generally installed inside the washing chamber 100.

[0104] Generally, due to frequent operation during daily use, long-term temperature changes, and the impact of water flow within the inner liner 1, tiny gaps can easily develop at the riveted joints of the inner liner 1 after prolonged exposure to the internal working environment. These gaps can become channels for water leakage. Simultaneously, the connection holes on the inner liner 1 wall used to connect various sensors may be altered by machine vibrations, leading to loose connections. Furthermore, the sealing material in these areas is easily damaged and rendered ineffective due to prolonged exposure to water, detergents, and temperature fluctuations, thus causing water leakage.

[0105] To address this, this embodiment includes a leakage detection device 3 on the base 2 to quickly and effectively detect water leakage in the inner tank 1. Specifically, the base 2 is connected to and located below the inner tank 1, serving as a crucial structure supporting the inner tank 1 and other internal components. As shown in Figures 4 and 5, the base 2 comprises a base body 21 and side plates 22 connected to the periphery of the base body 21. The base body 21 is a plate-like structure, the thickness and material of which can be selected based on the overall weight and structural strength requirements of the dishwasher. The side plates 22 are connected to the periphery of the base body 21. Exemplarily, the side plates 22 include a first side plate 2201, a second side plate 2202, and a third side plate 2203. The second side plate 2202 connects to both the first side plate 2201 and the third side plate 2203. The base 2 also includes a guide plate 23 opposite to the second side plate 2202, located on the front side of the base 2. It is understood that the front side of the base 2 referred to here is the side closest to the user during normal use of the dishwasher. The guide plate 23, the first side plate 2201, the second side plate 2202, and the third side plate 2203, together with the base body 21, form a relatively enclosed base space for mounting the inner liner 1 or electrical components. The side plates 22 can be connected by welding, riveting, or other reliable connection methods to ensure the overall stability of the base 2.

[0106] The side panel 22 includes a support structure 221, which is located on top of the side panel body. The support structure 221 at least partially overlaps with the outer wall of the inner liner 1 in the vertical direction. That is, in the vertical direction, because the support structure 221 at least partially overlaps with the outer wall of the inner liner 1, leakage from the outer wall of the inner liner 1 will drip onto the support structure 221 under the influence of gravity. The support structure 221 has an electrical mounting part 220, which is located inside the bottom of the inner liner 1, that is, in the internal space below the inner liner 1. The bottom of the inner liner 1 provides some shielding for the electrical mounting part 220. The electrical mounting part 220 is configured to mount electrical components, and its shape and size can be determined according to the type and number of electrical components to be mounted. For example, if multiple sensors and filters are to be mounted, the electrical mounting part 220 will have multiple mounting holes and slots of different sizes.

[0107] Since the support structure 221 has an electrical mounting section 220 configured for installing electrical components and needs to collect leakage from the inner liner 1, the support structure 221 in this embodiment also has a drainage channel 300. The drainage channel 300 is another important structure on the support structure 221, mainly configured to divert leakage from the inner liner 1, avoiding the electrical mounting section 220, and directing the leakage to the collection tank 200. The starting position of the drainage channel 300 is located below or around the overlapping part of the support structure 221 and the inner liner 1, so as to collect leakage from the inner liner 1 to the greatest extent. The shape of the drainage channel 300 can be straight, arc-shaped, trapezoidal, or other shapes that facilitate liquid flow.

[0108] A water collection tank 200 is provided on the base body 21. The water collection tank 200 is a space formed on the base body 21 through a processing technology, and can be a groove or other shape with a certain slope. The bottom and surrounding walls of the water collection tank 200 have good sealing properties to prevent leakage from the water collection tank 200 without being detected. The water collection tank 200 is connected to the drainage channel 300 on the side plate 22 to form a complete leakage diversion and detection channel.

[0109] The leak detection device 3 is installed in the water collection tank 200 of the mounting base 21. The leak detection device 3 may include a liquid level sensor, which can be based on different principles, such as a float-type liquid level sensor or a capacitive liquid level sensor. Taking a float-type liquid level sensor as an example, the float-type sensor mainly consists of a float and a microswitch. When there is no leakage in the water collection tank 200, the float is at the bottom or lower position of the water collection tank 200. When water leaks from the inner tank 1, the leaked liquid flows into the water collection tank 200 and reaches a certain level, causing the float to rise under the action of buoyancy. As the float rises, when it contacts the microswitch, the state of the microswitch changes, thereby triggering an alarm signal. The float-type sensor has a simple and reliable structure and can quickly respond to leaks in the dishwasher, ensuring that the dishwasher can issue an alarm in a timely manner when a leak occurs.

[0110] In this embodiment, because the support structure 221 partially overlaps with the outer wall of the inner tank 1, when the inner tank 1 leaks, the leaking liquid drips onto the support structure 221. The drain groove 300 on the support structure 221 can quickly guide the leaking liquid to the water collection groove 200 of the base body 21. Whether it is a small leak or a large leak, the leak detection device 3 located in the water collection groove 200 can detect it in time and issue an alarm signal immediately. At the same time, the drain groove 300 collects the leaking liquid in a specific flow channel, so that the leaking liquid completely avoids the electrical mounting part 220 during the process of flowing to the water collection groove 200. In this way, even if the inner tank 1 leaks, the leaking liquid will not come into contact with the electrical components installed in the electrical mounting part 220, thereby avoiding damage such as short circuits and corrosion of electrical components due to contact with leaking liquid, improving the safety and reliability of the dishwasher, and extending the service life of electrical components.

[0111] Please refer to Figures 5 and 6. Figure 6 is an enlarged view of point A in Figure 5.

[0112] In some embodiments, the support structure 221 is inclined, with the lower side of the inclined support structure 221 closer to the water collection tank 200. The inclined shape of the support structure 221 is an important design feature of this embodiment. The portion of the support structure 221 overlapping with the outer wall of the inner liner 1 and the entire platform surface maintain a certain inclination angle. For example, the inclination angle can be between 3° and 15°. The inclination direction is towards the water collection tank 200, i.e., the lower side is closer to the water collection tank 200. When leakage occurs in the inner liner 1, due to gravity and the effect of the inclined surface, the leakage will quickly flow towards the lower side. Compared to a horizontal support structure 221, the inclined support structure 221 significantly accelerates the flow rate of the leakage, thereby guiding the leakage to the water collection tank 200 more promptly.

[0113] In some embodiments, the drainage trough 300 has a manifold 303 to further optimize the collection and diversion of leaked liquid. The manifold 303 is located on the lower side of the pier structure 221 and faces the collection tank 200. The shape of the manifold 303 can be rectangular, trumpet-shaped, etc. In the trumpet-shaped manifold 303, its larger opening faces most of the area of ​​the pier structure 221, and its smaller opening faces the collection tank 200. This allows leaked liquid from various locations on the pier structure 221 to be collected more efficiently. When the leaked liquid flows on the inclined pier structure 221, it will gather towards the manifold 303. The position and orientation of the manifold 303 ensure that the leaked liquid can be accurately guided into the collection tank 200. Moreover, the trumpet-shaped manifold 303 can reduce energy loss and splashing during the collection process, ensuring that the leaked liquid enters the diversion channel in a relatively stable state and then flows to the collection tank 200.

[0114] As shown in Figure 6, in some embodiments, the support structure 221 has an outer perimeter plate 2213 and an inner perimeter plate 2214 spaced apart. The outer perimeter plate 2213 is located at the outer edge of the support structure 221, forming a continuous boundary around the perimeter of the support structure 221. The outer perimeter plate 2213 is configured to prevent splashing of leaked liquid. For example, when the dishwasher is spraying at high speed, if the inner tank 1 leaks water, the outer perimeter plate 2213 can effectively block splashing caused by the water flow impact. The inner perimeter plate 2214 cooperates with the outer perimeter plate 2213 to jointly enclose and form a drainage channel 300. The height of the inner perimeter plate 2214 is generally slightly lower than that of the outer perimeter plate 2213, which can ensure a reasonable liquid level difference in the drainage channel 300, which is conducive to the flow of leaked liquid in the drainage channel 300. The inner perimeter plate 2214 can be an integrally formed structure with the support structure 221, or it can be fixed to the support structure 221 through a special installation process. Its shape can be straight or curved according to the shape of the drainage channel 300, so as to better guide the flow of the leaking liquid.

[0115] In this embodiment, by concentrating the leaked liquid within the drain trough 300, the leaked liquid can be accurately guided to the collection trough 200, enabling the leak detection device 3 to detect the leakage of the inner tank 1 more promptly and accurately, thereby ensuring the normal operation of the dishwasher and extending its service life. Simultaneously, the design of the drain trough 300 also prevents the leaked liquid from overflowing or flowing back to other unwanted areas during its flow, further improving the safety of the dishwasher.

[0116] Please refer to Figures 5 and 7. Figure 7 is a schematic diagram of the section broken along the dashed line in Figure 5.

[0117] In some embodiments, the support structure 221 includes at least two supports, with a third support 2211 located on the outermost side of the side plate 22 and having a higher height than the first support 2212. The third support 2211 at least partially overlaps with the outer wall of the inner liner 1 in the vertical direction. When leakage occurs in the inner liner 1, the leakage will drip onto the third support 2211 under the influence of gravity. The third support 2211 acts as a collection tray, catching the leakage and preventing it from flowing directly to the electrical mounting section 220. The connection between the third support 2211 and the side plate 22 can be integrally formed to ensure structural stability.

[0118] The first support platform 2212 is located on the inner side of the bottom of the inner liner 1, that is, in the internal space below the inner liner 1, and the electrical mounting part 220 is located on the first support platform 2212. In this way, the bottom of the inner liner 1 covers the electrical mounting part 220, and the leakage will not directly contact the electrical components.

[0119] Similarly, when the foundation structure 221 includes three foundations, the third foundation is located on the side of the first foundation 2212 that is close to the water collection tank 200 and is lower than the first foundation 2212, so as to guide the leakage to the water collection tank 200.

[0120] In some embodiments, the drainage channel 300 includes a third drainage channel 301 disposed on the third support 2211 and a first drainage channel 302 disposed on the first support 2212, which work together to achieve orderly drainage of leaked liquid.

[0121] The third drainage channel 301 is located on the third support 2211 and is configured to receive leakage liquid that seeps from the inner liner 1 and drips onto the third support 2211. The inlet of the third drainage channel 301 can be an opening along the edge of the third support 2211 and towards the outer wall of the inner liner 1. The channel shape of the third drainage channel 301 can be arc-shaped or a straight line with a certain inclination to facilitate rapid flow of leakage liquid. The outlet of the third drainage channel 301 connects to the first drainage channel 302, and the position of the outlet matches the inlet of the first drainage channel 302 to ensure that leakage liquid can smoothly transition from the third drainage channel 301 to the first drainage channel 302.

[0122] The first drainage channel 302 is located on the first support 2212 and is configured to guide the leaked liquid from the third drainage channel 301 to the collection tank 200. The inlet of the first drainage channel 302 is connected to the outlet of the third drainage channel 301. The channel of the first drainage channel 302 can be a straight line with a certain slope to ensure that the leaked liquid can flow quickly to the collection tank 200 under the action of gravity. The outlet of the first drainage channel 302 is directly connected to the collection tank 200, and the position of the outlet must ensure that the leaked liquid can flow into the collection tank 200 accurately.

[0123] In this embodiment, the third drainage trough 301 can quickly collect the leaked liquid on the third support 2211 and guide it to the first drainage trough 302, which then smoothly transports the leaked liquid to the collection tank 200. The segmented design of the third drainage trough 301 and the first drainage trough 302 of the drainage trough 300 allows the leaked liquid to flow in an orderly manner along a predetermined path, improving the speed and accuracy of the leaked liquid flowing to the collection tank 200.

[0124] Please refer to Figure 7. In some embodiments, the electrical mounting section 220 plays a crucial role in mounting electrical components on the support structure 221. The electrical mounting section 220 includes a first mounting cavity 400 configured for mounting a first type of device. The shape and size of the first mounting cavity 400 can be designed according to the external shape of the first type of device (such as sensors, filters, and other small electrical components). For example, for irregularly shaped components such as filters, the shape of the first mounting cavity 400 will be adapted accordingly, possibly being a cuboid or other special shape. Simultaneously, the first mounting cavity 400 is provided with structures such as slots and screw holes configured for fixing components.

[0125] The support structure 221 also features a water-retaining rib 2215, which is configured to further enhance the protection of electrical components. The water-retaining rib 2215 is made of a material with good water resistance and mechanical strength, such as high-quality plastic or metal, ensuring that it will not be corroded or damaged in long-term contact with leaking liquids. Specifically, the water-retaining rib 2215 surrounds the first mounting cavity 400 and is positioned higher than the bottom wall of the drainage channel 300. In this way, the water-retaining rib 2215 forms a protective barrier around the electrical component mounting area, effectively preventing leaking liquid from entering the first mounting cavity 400. During normal use, leaking liquid is blocked outside the first mounting cavity 400 by the water-retaining rib 2215, thereby protecting the first type of device.

[0126] Please refer to Figure 5. In some embodiments, the base body 21 is further provided with a second mounting cavity 500 configured to mount a second type of device. The shape of the second mounting cavity 500 can be set according to the shape of the second type of device (such as a motor, water pump, etc.). The size of the second mounting cavity 500 is sufficient to accommodate these large electrical components, and a certain amount of space is reserved around it to facilitate the installation, disassembly, and maintenance of the components. The second mounting cavity 500 is connected to the water collection tank 200, so that leakage can flow from the second mounting cavity 500 to the water collection tank 200 for leakage detection.

[0127] A mounting section 211 is provided within the second mounting cavity 500, playing a crucial role in protecting the second type of device. The mounting section 211 is configured to space the second type of device from the bottom wall of the second mounting cavity 500. The mounting section 211 can be a support structure with a certain height, such as a support block or support frame made of high-strength plastic or metal. The height of the mounting section 211 can be determined based on the expected leakage depth and the size of the second type of device, ensuring sufficient space between the bottom of the second type of device and the bottom wall of the second mounting cavity 500 to prevent leakage from accumulating at the bottom of the second mounting cavity 500 and contacting the second type of device. This spaced installation method ensures that even if leakage enters the second mounting cavity 500, the bottom of the second type of device remains dry, preventing damage such as short circuits and corrosion due to contact with the leakage.

[0128] In some embodiments, the second mounting cavity 500 is further provided with an overflow hole 501. The overflow hole 501 is an important structure to prevent leakage from accumulating excessively in the second mounting cavity 500 and threatening the safety of the second type of device. The inlet of the overflow hole 501 is higher than the bottom wall of the second mounting cavity 500, and its height can be determined according to the bottom height of the second type of device and the safety margin. At the same time, the bottom of the second type of device is higher than the inlet of the overflow hole 501. In this way, when leakage accumulates in the second mounting cavity 500 and the water level gradually rises, once the water level exceeds the height of the overflow hole 501, the leakage will flow out from the overflow hole 501 without contacting the second type of device, reducing the risk of damage to the second type of electrical components due to leakage and improving the service life and reliability of these components.

[0129] Please refer to Figures 4 and 8. Figure 8 is a schematic diagram of the structure of the guide plate 23 provided in the embodiment of this application.

[0130] In some embodiments, the deflector 23 is attached to the front edge of the base body 21 and configured to divert leakage that may seep from the poorly sealed opening between the door and the washing chamber 100. The deflector 23 is located on the front of the dishwasher, near the lower part of the door. This location allows for interception and diversion of leakage as soon as it begins to appear near the door. The length of the deflector 23 can be determined based on the width of the dishwasher door, typically covering the door width to ensure that leakage from any location near the door can be caught.

[0131] In some embodiments, the guide plate 23 includes a connecting portion 231 and a guide portion 232 connected together, with the connecting portion 231 connected to the front edge of the base body 21. The connection can be achieved by snap-fitting, riveting, or bonding with sealant. The shape and size of the connecting portion 231 match the front edge of the base body 21.

[0132] The guide section 232 is inclined, which allows gravity to be used more effectively to guide the leaked liquid to the collection tank 200. The lower side of the inclined guide section 232 is closer to the collection tank 200, so that the leaked liquid will naturally flow along the inclined surface of the guide section 232 to the collection tank 200 under the action of gravity.

[0133] When the seal between the door and the open washing chamber 100 is poor, washing water may leak out. The deflector plate 23, located on the front side of the base 2 and near the lower part of the door, is positioned along the potential path of leakage, thus catching any leakage flowing from near the door and inner tub 1. The inclined design of the deflector plate 232 utilizes gravity, causing leakage to flow quickly along its inclined surface towards the collection tank 200 after contact with the deflector plate 23. This reduces the possibility of leakage corroding and damaging electrical components installed on the front side of the base 2. Simultaneously, it prevents leakage from accumulating at the front of the dishwasher, keeping the surrounding environment dry and clean, and improving user safety and comfort.

[0134] In some embodiments, please refer to Figures 1 to 5. This application embodiment further provides a dishwasher, which includes an inner tank 1, a base assembly 20, and a leakage detection device 3, which can realize the collection, diversion and detection of leakage, thereby improving the operating safety of the dishwasher.

[0135] The bottom or side wall of the inner liner 1 is provided with a dripping position for leaking liquid to drip down. When the inner liner 1 experiences sealing aging, loosening of the interface, or other issues, the leaking liquid will drip from this position. The base assembly 20 is connected to the inner liner 1 and located below the inner liner 1. The base assembly 20 includes a base 2 and a water-blocking structure 202. The base 2 includes a base body 21 and a side plate 22 connected to the periphery of the base body 21. A water collection groove 200 is provided on the base body 21 to collect leaking liquid. The side plate 22 includes a support structure 221, which may be integrally formed on the top of the side plate 22. The support structure 221 at least partially overlaps with the outer side wall of the inner liner 1 in the vertical direction. The support structure 221 has an electrical mounting part 220 and a drain trough 300. The electrical mounting part 220 is located on the inner side of the bottom of the inner tank 1 and is configured to install electrical components of the dishwasher. The drain trough 300 is connected to the water collection tank 200 and can divert the leaked liquid to the water collection tank 200 while avoiding the electrical mounting part 220 to prevent the leaked liquid from contacting the electrical components.

[0136] A water-blocking structure 202 is connected above the support structure 221. The water-blocking structure 202 has an upward-facing water-receiving groove 202A, which is connected to the drainage groove 300. When the inner liner 1 is installed on the base 2, the water-receiving groove 202A is located below the dripping position of the inner liner 1 to receive the leaking liquid and guide it to the drainage groove 300. A leakage detection device 3 is installed in the water collection groove 200 of the base body 21 and is configured to monitor leakage in the water collection groove 200 in real time.

[0137] When the inner tub 1 of the dishwasher leaks during operation, the leaking liquid drips from the dripping point and is first caught by the water receiving tank 202A of the water-blocking structure 202 below, preventing the liquid from splashing. The leaking liquid in the water receiving tank 202A flows along the tank body into the drain tank 300. Under the guidance of the drain tank 300, the leaking liquid bypasses the area where the electrical installation part 220 is located and flows to the water collection tank 200 of the base body 21. As the leaking liquid accumulates in the water collection tank 200, the leak detection device 3 detects the leak and immediately issues an alarm signal.

[0138] In this embodiment, the guide design of the water receiving tank 202A and the drain tank 300 avoids the electrical installation part 220, thereby avoiding safety hazards such as short circuits and component damage caused by leakage. At the same time, the design of the water receiving tank 202A being opposite to the dripping position and the drain tank 300 being connected to the water collection tank 200 ensures that the leaked liquid will not splash during the dripping and collection process, improving the efficiency of leakage collection. In addition, the leaked liquid flows directly into the detection area in the water collection tank 200, and the detection device can quickly detect the leakage, reducing the risk of dishwasher malfunction.
