Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a dishwasher. Background Technology

[0002] Dishwashers, as a widely used dishwashing appliance, provide great convenience to people. A dishwasher generally consists of an inner tub and a base that supports it. The inner tub is a key component, primarily used to hold dishes and washing water, playing a crucial role in the dishwashing process. The base typically houses electrical components (such as sensors and filters).

[0003] However, dishwasher inner tubs may pose a risk of leakage. Firstly, the inner tub wall is typically constructed by riveting side panels to the top and bottom panels; over time, tiny gaps can develop at these joints, leading to water seepage. Secondly, the inner tub wall has connection holes for electrical components; machine vibrations can loosen these connections, and the seals at these joints may fail due to water, detergent, and temperature, further contributing to leakage.

[0004] Leaking water may drip down the outer wall of the inner tank and come into contact with the electrical components mounted on the base, causing problems such as short circuits and corrosion, seriously affecting the normal operation of the dishwasher. Therefore, it is very important to quickly and effectively detect leaks in the dishwasher's inner tank. Utility Model Content

[0005] This application provides a dishwasher that can quickly and effectively detect leaks in the dishwasher's inner tank, thereby ensuring the normal operation of the dishwasher.

[0006] To achieve the above objectives, embodiments of this application provide a dishwasher, comprising:

[0007] Inner liner;

[0008] A base, connected to and located below the inner liner, includes a bottom plate and side plates connected to the periphery of the bottom plate. A detection cavity is provided on the bottom plate, and an installation platform is provided on the top of the side plates. The installation platform and the outer wall of the inner liner at least partially overlap in the vertical direction. The installation platform has an electrical mounting part and a drainage channel. The electrical mounting part is located inside the bottom of the inner liner, and the drainage channel communicates with the detection cavity. The drainage channel is used to guide leaked liquid from the inner liner, avoiding the electrical mounting part and directing it to the detection cavity.

[0009] A leakage detection device is installed in the detection chamber of the base plate.

[0010] In some embodiments, the mounting platform includes at least two steps, wherein the first step is located on the outermost side of the side panel and is higher than the second step, the first step and the outer side wall of the inner liner at least partially overlap in the vertical direction, the second step is located on the inner side of the bottom of the inner liner, and the electrical installation part is disposed on the second step.

[0011] In some embodiments, the guide channel includes a first guide section disposed on the first step and a second guide section disposed on the second step, the outlet of the first guide section being connected to the second guide section, and the outlet of the second guide section being connected to the detection cavity.

[0012] In some embodiments, the mounting platform is tilted, with the lower side of the tilted mounting platform closer to the detection cavity.

[0013] In some embodiments, the flow channel has a confluence port located on the lower side of the mounting platform and facing the detection cavity.

[0014] In some embodiments, the mounting platform has spaced-apart edging and baffles, the edging being located at the outer edge of the mounting platform, and the baffles and edging forming the flow channel.

[0015] In some embodiments, the mounting platform further has a water-retaining rib, and the electrical mounting part includes a first mounting cavity for mounting a first type of device, the water-retaining rib surrounding the first mounting cavity and being disposed above the bottom wall of the guide channel.

[0016] In some embodiments, the base plate is further provided with a second mounting cavity for mounting the second type of device. The second mounting cavity is in communication with the detection cavity. The second mounting cavity is provided with a mounting part for mounting the second type of device at a distance from the bottom wall of the second mounting cavity.

[0017] In some embodiments, the second mounting cavity is further provided with an overflow hole, the inlet of which is higher than the bottom wall of the second mounting cavity.

[0018] In some embodiments, the side plate includes a first side plate, a second side plate, and a third side plate, wherein the second side plate is connected to the first side plate and the third side plate respectively;

[0019] The base also includes a guide plate, which is connected to the edge of the base plate and is disposed opposite to the second side plate. The guide plate is used to guide the leakage liquid seeping from the inner liner to the detection chamber.

[0020] In some embodiments, the guide plate includes a connecting portion and a guide portion connected together, the connecting portion being connected to the edge of the base plate, and the guide portion being inclined, with the lower side of the inclined guide portion closer to the detection cavity.

[0021] In the dishwasher provided in this embodiment, the mounting platform and the outer wall of the inner tub at least partially overlap in the vertical direction, allowing the mounting platform to catch any leakage from the inner tub. A guide channel on the mounting platform quickly directs the leakage to the detection chamber. A leakage detection device located in the detection chamber detects the leakage and issues an alarm, thus quickly and effectively preventing water leakage from the dishwasher's inner tub and ensuring the dishwasher's normal operation. Simultaneously, the guide channel collects the leakage in a specific flow channel, avoiding the electrical mounting parts, thereby preventing the leakage from contacting electrical components and causing damage, and improving safety.

[0036] A dishwasher is a common dishwashing appliance, whose main structure includes an inner tub and a base that supports it. The inner tub, as a key component, is responsible for holding the dishes and washing water, ensuring the smooth operation of the dishwashing process. The base is an important location for installing various electrical components (such as sensors and filters), which are essential for the dishwasher's proper functioning.

[0037] However, current dishwashers face the problem of leaking inner tubs during use. Structurally, the inner tub's walls are typically assembled from side panels riveted to the top and bottom plates. Over time, due to various factors such as frequent operation, prolonged temperature changes, and water flow within the tub, tiny gaps can develop at the riveted joints, becoming channels for water leakage. Additionally, the inner tub wall contains connection holes for electrical components. During dishwasher operation, vibrations are inevitable, 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.

[0038] 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.

[0039] Therefore, this application 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.

[0040] Specifically, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a dishwasher provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of the base and leakage detection device provided in one embodiment of this application; Figure 3 This is a schematic diagram of the base and leakage detection device provided in another embodiment of this application.

[0041] The dishwasher in this embodiment includes a shell, an inner tub 1, a base 2, and a leakage detection device 3. The shell of the dishwasher 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 usually made of a material with a certain strength and corrosion resistance, such as thin metal sheet 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, which can be easily opened and closed. Furthermore, the door can also be equipped with an operation panel for users to select washing programs, start or stop the dishwasher, etc.

[0042] 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 in 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.

[0043] 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.

[0044] To address this, this embodiment incorporates a leakage detection device 3 in the base 2 to quickly and effectively detect water leakage in the inner liner 1. Specifically, the base 2 is connected to and located below the inner liner 1, and is a crucial structure supporting the inner liner 1 and other internal components. Figure 2 and Figure 3As shown, the base 2 includes a base plate 21 and side plates 22 connected to the periphery of the base plate 21. The base plate 21 is a plate-like structure, the thickness and material of which can be selected according to the overall weight and structural strength requirements of the dishwasher. The side plates 22 are connected to the periphery of the base plate 21. Exemplarily, the side plates 22 include a first side plate 10, a second side plate 20, and a third side plate 30. The second side plate 20 is connected to the first side plate 10 and the third side plate 30 respectively. The base 2 also includes a guide plate 23 opposite to the second side plate 20, 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 human body when the dishwasher is in normal use. The guide plate 23, the first side plate 10, the second side plate 20, and the third side plate 30, together with the base plate 21, constitute a relatively enclosed space of the base 2 for installing the inner tank 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.

[0045] A mounting platform 221 is provided on the top of the side panel 22, and the mounting platform 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 mounting platform 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 mounting platform 221 under the action of gravity. The mounting platform 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 a certain degree of shielding for the electrical mounting part 220. The electrical mounting part 220 is used to install electrical components, and its shape and size can be determined according to the type and number of electrical components to be installed. For example, if multiple sensors and filters are to be installed, the electrical mounting part 220 will have multiple mounting holes and slots of different sizes.

[0046] Since the mounting platform 221 has an electrical mounting section 220 for mounting electrical components and needs to collect leakage from the inner liner 1, the mounting platform 221 in this embodiment also has a guide channel 300. The guide channel 300 is another important structure on the mounting platform 221, mainly used to divert the leakage from the inner liner 1 to avoid the electrical mounting section 220 and guide the leakage to the detection chamber 200. The starting position of the guide channel 300 is located below or around the overlapping part of the mounting platform 221 and the inner liner 1, so as to collect the leakage from the inner liner 1 to the greatest extent. The shape of the guide channel 300 can be straight, arc-shaped, trapezoidal, or other shapes that are conducive to liquid flow.

[0047] A detection cavity 200 is provided on the base plate 21. The detection cavity 200 is a space formed on the base plate 21 through a processing technology, and can be a groove or other shape with a certain slope. The bottom and surrounding walls of the detection cavity 200 have good sealing properties to prevent leakage from the detection cavity 200 without being detected. The detection cavity 200 is connected to the guide groove 300 on the side plate 22 to form a complete leakage guide and detection channel.

[0048] The leak detection device 3 is installed in the detection chamber 200 of the base plate 21. The leak detection device 3 may include a liquid level sensor, which can be a sensor 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 detection chamber 200, the float is at the bottom or lower position of the detection chamber 200. When water leaks from the inner tank 1, the leaked liquid flows into the detection chamber 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.

[0049] In this embodiment, due to the partial overlap between the mounting platform 221 and the outer wall of the inner tank 1, when the inner tank 1 leaks, the leaking liquid drips onto the mounting platform 221. The guide channel 300 on the mounting platform 221 can quickly guide the leaking liquid to the detection chamber 200 of the base plate 21. Whether it is a small leak or a large-scale leak, the leak detection device 3 located in the detection chamber 200 can detect it in time and issue an alarm signal immediately. At the same time, the guide channel 300 collects the leaking liquid in a specific flow channel, so that the leaking liquid completely avoids the electrical mounting part 220 during its flow to the detection chamber 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 the electrical components due to contact with the leaking liquid, improving the safety and reliability of the dishwasher, and extending the service life of the electrical components.

[0050] Please see Figure 3 and Figure 4 , Figure 4 for Figure 3 Enlarged view of point A in the middle.

[0051] In some embodiments, the mounting platform 221 is inclined, with the lower side of the inclined mounting platform 221 closer to the detection cavity 200. The inclined shape of the mounting platform 221 is an important design feature of this embodiment. The portion of the mounting platform 221 overlapping with the outer wall of the inner liner 1, as well as the entire platform surface, maintains a certain inclination angle. For example, the inclination angle can be between 3° and 15°. The inclination direction is towards the detection cavity 200, i.e., the lower side is closer to the detection cavity 200. When the inner liner 1 leaks liquid, due to gravity and the effect of the inclined surface, the leaked liquid will quickly flow towards the lower side. Compared to a horizontal mounting platform 221, the inclined mounting platform 221 significantly accelerates the flow rate of the leaked liquid, thereby guiding the leaked liquid to the detection cavity 200 more promptly.

[0052] Furthermore, the guide channel 300 has a manifold 303, which further optimizes the collection and guidance functions of the leaking liquid. The manifold 303 is located on the lower side of the mounting platform 221 and faces the detection chamber 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 mounting platform 221, and its smaller opening faces the detection chamber 200. In this way, the leaking liquid collected from various positions on the mounting platform 221 can be collected more efficiently. When the leaking liquid flows on the inclined mounting platform 221, it will gather towards the manifold 303. The position and orientation of the manifold 303 ensure that the leaking liquid can be accurately guided into the detection chamber 200. Moreover, the trumpet-shaped manifold 303 can reduce energy loss and splashing during the collection process, ensuring that the leaking liquid enters the guide channel in a relatively stable state and then flows to the detection chamber 200.

[0053] like Figure 4 As shown, in some embodiments, the mounting platform 221 has spaced-apart perimeters 2213 and baffles 2214. The perimeters 2213 are located at the outer edge of the mounting platform 221, forming a continuous boundary around the perimeter of the mounting platform 221. The perimeters 2213 are used to prevent splashing of leaked liquid. For example, when the dishwasher is spraying at high speed, if the inner tank 1 leaks, the perimeters 2213 can effectively block splashing caused by the water flow. The baffles 2214 cooperate with the perimeters 2213 to jointly form a flow channel 300. The height of the baffles 2214 is generally slightly lower than that of the perimeters 2213, which ensures a reasonable liquid level difference within the flow channel 300, facilitating the flow of leaked liquid within the flow channel 300. The baffles 2214 can be an integrally formed structure with the mounting platform 221, or it can be fixed to the mounting platform 221 through a special installation process. Its shape can be straight or designed as an arc according to the shape of the flow channel 300, to better guide the flow of leaked liquid.

[0054] In this embodiment, by concentrating the leaked liquid within the guide channel 300, the leaked liquid can be accurately guided to the detection chamber 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 guide channel 300 also prevents the leaked liquid from overflowing or flowing back to other unwanted areas during the flow process, further improving the safety of the dishwasher.

[0055] Please see Figure 3 and Figure 5 , Figure 5 for Figure 3 A schematic diagram of the section broken along the dotted line.

[0056] In some embodiments, the mounting platform 221 includes at least two steps. The first step 2211 is located on the outermost side of the side panel 22 and its height is higher than that of the second step 2212. The first step 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 first step 2211 under the action of gravity. The first step 2211 acts as a collection tray, catching the leakage and preventing it from flowing directly to the electrical mounting part 220. The connection between the first step 2211 and the side panel 22 can be integrally formed to ensure structural stability.

[0057] The second step 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 second step 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.

[0058] Similarly, when the mounting platform 221 includes three steps, the third step is located on the side of the second step 2212 that is close to the detection chamber 200 and is lower than the second step 2212, so as to guide the leakage liquid to the detection chamber 200.

[0059] Furthermore, the guide channel 300 includes a first guide section 301 located on the first step 2211 and a second guide section 302 located on the second step 2212, which work together to achieve orderly guidance of the leaking liquid.

[0060] The first guide section 301 is located on the first step 2211 and is used to receive leakage liquid that seeps from the inner liner 1 and drips onto the first step 2211. The inlet of the first guide section 301 can be an opening along the edge of the first step 2211 and towards the outer wall of the inner liner 1. The channel shape of the first guide section 301 can be arc-shaped or a straight line with a certain inclination to facilitate rapid flow of leakage liquid. The outlet of the first guide section 301 connects to the second guide section 302, and the position of the outlet matches the inlet of the second guide section 302 to ensure that leakage liquid can smoothly transition from the first guide section 301 to the second guide section 302.

[0061] The second guide section 302 is located on the second step 2212 and is used to guide the leaked liquid from the first guide section 301 to the detection chamber 200. The inlet of the second guide section 302 is connected to the outlet of the first guide section 301. The channel of the second guide section 302 can be a straight line with a certain slope to ensure that the leaked liquid can flow quickly to the detection chamber 200 under the action of gravity. The outlet of the second guide section 302 is directly connected to the detection chamber 200, and the position of the outlet must ensure that the leaked liquid can flow into the detection chamber 200 accurately.

[0062] In this embodiment, the first guide section 301 can quickly collect the leaked liquid on the first step 2211 and guide it to the second guide section 302, which then smoothly delivers the leaked liquid to the detection chamber 200. The segmented design of the first guide section 301 and the second guide section 302 of the guide channel 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 detection chamber 200.

[0063] Please continue reading. Figure 5 In some embodiments, the electrical mounting section 220 plays a crucial role in mounting electrical components on the mounting platform 221. The electrical mounting section 220 includes a first mounting cavity 400 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 a sensor, filter, or other small electrical component). 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 for fixing the component.

[0064] The mounting platform 221 also features a water-retaining rib 2215, which further enhances 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 it will not corrode or be 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 guide 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, thus protecting the first type of device.

[0065] Please continue reading. Figure 3In some embodiments, the base plate 21 is further provided with a second mounting cavity 500 for mounting the 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 detection cavity 200, so that leakage can flow from the second mounting cavity 500 to the detection cavity 200 for leakage detection.

[0066] 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 used 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.

[0067] Furthermore, the second mounting cavity 500 is also 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.

[0068] Please see Figure 2 and Figure 6 , Figure 6 This is a schematic diagram of the structure of the guide plate 23 provided in the embodiment of this application.

[0069] In some embodiments, the deflector 23 is attached to the front edge of the base plate 21 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.

[0070] Furthermore, 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 plate 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 plate 21.

[0071] The guide section 232 is inclined, which allows for better use of gravity to guide the leaking liquid to the detection chamber 200. The lower side of the inclined guide section 232 is closer to the detection chamber 200, so that the leaking liquid will naturally flow along the inclined surface of the guide section 232 to the detection chamber 200 under the action of gravity.

[0072] 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 towards the detection chamber 200 along its inclined surface 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.
