Description

Technical Field

[0001] This invention relates to the field of dishwasher base technology, and more particularly to a corner bracket for a dishwasher and a dishwasher base frame. Background Technology

[0002] While modern household dishwashers prioritize high-efficiency cleaning and energy saving, their operational reliability and waterproof safety are increasingly important. Dishwashers have a water inlet valve to control water supply; if this component malfunctions, water will continuously flow into the inner tank, causing the internal water level to rise abnormally. Currently, most dishwasher base structures focus primarily on support and frame connection, lacking proactive drainage and emergency response mechanisms for such internal overflows. When an overflow occurs, if the water level exceeds the edge of the inner tank or seeps from component seams, it will spread directly to the outside of the dishwasher, soaking the kitchen floor and causing property damage and safety hazards.

[0003] The flaw in existing designs lies in the fact that corner brackets fail to utilize their lowest-positioned location. Even when water has reached the corner bracket, the emergency mechanism cannot be triggered, causing the water to continue rising and seep out of the machine through gaps. Therefore, there is an urgent need to develop a corner bracket and base frame for dishwashers to solve the problem of existing corner brackets failing to utilize their lowest-positioned location for overflow monitoring and drainage. Summary of the Invention

[0010] Furthermore, the drainage plate is detachably connected to the corner bracket.

[0011] Furthermore, the drain plate is provided with a plug-in portion, and the corner bracket is provided with a plugged-in portion that mates with the plug-in portion, the plug-in portion being inserted downward into the plugged-in portion.

[0012] Furthermore, the corner code is made of plastic.

[0013] A dishwasher base frame includes a dishwasher inner tub, a base frame, sheet metal parts, and corner brackets. The dishwasher inner tub is provided with an overflow drain hole, and the overflow drain hole, the flow channel of the guide plate, and the overflow hole are connected in sequence along the overflow water direction. The corner brackets are formed at the corners of the base frame.

[0014] Furthermore, the base frame of a dishwasher also includes a water collection tray and a water sensing mechanism; the water collection tray is located below the overflow hole; the water sensing mechanism includes a control system and a water sensing sensor located on the water collection tray; the dishwasher inner tub is equipped with an electric drain valve; the control system is electrically connected to the water sensing sensor and the electric drain valve.

[0015] Furthermore, there are multiple corner brackets with overflow holes, which are located at both ends of the same side of the annular frame.

[0016] Furthermore, the corner bracket is installed on the corresponding sheet metal part by injection molding.

[0017] Furthermore, the corner bracket is connected to the sheet metal part via a snap-fit ​​structure.

[0018] Furthermore, the snap-fit ​​structure includes a snap-fit ​​groove provided on the sheet metal part and a snap-fit ​​part provided on the corner bracket; the snap-fit ​​groove includes a slot and a locking groove, and the slot and the locking groove belonging to the same snap-fit ​​groove are interconnected; the snap-fit ​​part slides into the slot and then snaps into the locking groove.

[0019] Furthermore, both ends of the sheet metal part are connecting ends; the buckle structure includes multiple snap-fit ​​grooves and multiple snap-fit ​​parts; each connecting end is provided with at least two snap-fit ​​grooves, and multiple snap-fit ​​parts are provided on the corner brackets, and the snap-fit ​​parts on each corner bracket are snapped into the corresponding snap-fit ​​grooves on two adjacent sheet metal parts; the sheet metal part has an inner liner support part, which is used to connect the inner liner support piece.

[0020] Furthermore, the inner liner support is located between the two snap-fit ​​grooves at the same connecting end.

[0021] Furthermore, the inner liner support is located between two snap-fit ​​grooves that are spaced apart in the horizontal direction at the same connecting end.

[0023] Furthermore, the inner liner support plate, the sheet metal parts, and the corner brackets are arranged in a sequentially stacked manner from the outside of the dishwasher to the inside of the dishwasher.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. The corner bracket, integrated into the dishwasher base frame, serves as a fixed component, ensuring installation stability and structural integrity. The corner bracket features an overflow hole, with one end connecting to the dishwasher's inner tub and the other to a water sensor. This overflow hole creates a continuous flow path from the inner tub to the water sensor, enabling orderly water flow and monitoring. This structural design, through the integrated layout of the corner bracket and the connectivity of the overflow hole, enhances the compactness and reliability of the dishwasher water monitoring system.

[0026] 2. This structural design, through the integrated layout of the corner brackets and the interconnectivity of the overflow holes, achieves the integrated function of overflow guidance and water detection within a limited space, improving the structural compactness and reliability of the dishwasher water monitoring system. The addition of a flow channel-equipped guide plate based on the corner brackets enables the collection and guidance of overflow water; the guide groove between the guide plate and the corner brackets further optimizes the water flow path, ensuring a smooth water transition; and the detachable connection design between the guide plate and the corner brackets greatly facilitates component installation and daily maintenance and cleaning.

[0027] 3. Based on the fact that the corner code is formed at the corner of the base frame, the overflow monitoring function module is directly integrated into the structural component of the frame, realizing the integration of function and support structure, which greatly saves internal space; by setting the overflow drain hole of the dishwasher inner tub at the corner of the inner tub and directly connecting it with the water inlet of the diversion plate, the corner code set at the corner of the base frame corresponds to the water inlet of the diversion plate set at the corner of the inner tub, so that the water sensing mechanism in the corner code can detect and receive the overflow water in the first time; based on the layout of the overflow drain hole, the flow channel of the diversion plate, and the overflow hole connected in sequence along the overflow water direction, a complete and closed overflow path is constructed from the corner of the inner tub to the water sensing mechanism, ensuring that the overflow water can be reliably guided to the monitoring point.

Detailed Implementation

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] See Figures 1-4 A preferred embodiment of the present invention is described below:

[0037] An angle bracket for a dishwasher, angle bracket 100, is integrated into the dishwasher base frame 400. The angle bracket 100 has an overflow hole 1100, one end of which connects to the dishwasher inner tub 1000, and the other end connects to a water sensing mechanism. The core function of this angle bracket for a dishwasher is to provide an integrated component that combines structural connection and overflow guidance functions, thereby achieving orderly discharge and reliable monitoring of overflow water.

[0038] The corner bracket 100 is an integrated part of the dishwasher base frame 400, and its body has the structural characteristics of connection and support. The corner bracket 100 has a dedicated overflow hole 1100, which is spatially configured to have two communicating ports: one end is configured to communicate with the bottom or side wall area of ​​the dishwasher's inner tub, and the other end is configured to communicate with a separately set water sensing mechanism.

[0039] When the dishwasher inner tub 1000 overflows, excess water enters the overflow hole 1100 inlet of the corner bracket 100 through the opening on the inner tub. Subsequently, under the influence of gravity, the water flows through the overflow hole 1100 channel inside the corner bracket 100 and is finally discharged from the overflow hole 1100 outlet of the corner bracket 100, being guided to the connected water sensing mechanism. Upon receiving the water flow signal, the water sensing mechanism triggers the corresponding control logic of the dishwasher, thereby achieving real-time monitoring and safety protection against overflow.

[0040] It is understandable that the corner bracket 100, integrated into the dishwasher base frame 400, serves as a fixed integrated component of the dishwasher base frame 400, ensuring installation stability and structural integrity. The corner bracket 100 is equipped with an overflow hole 1100, with one end connecting to the dishwasher inner tub 1000 and the other end connecting to the water sensing mechanism. The overflow hole 1100 forms a continuous flow path from the inner tub to the water sensing mechanism, achieving orderly guidance and monitoring of overflow water. This structural design, through the integrated layout of the corner bracket 100 and the connectivity of the overflow hole 1100, improves the structural compactness and reliability of the dishwasher water monitoring system.

[0041] In practice, the corner bracket 100 can be fixedly installed at the corner of the dishwasher base frame 400 by welding, riveting, or bolting. The overflow hole 1100 can be directly cast or drilled on the body of the corner bracket 100. Its inlet end is connected to the overflow outlet of the inner tank through a pipe or directly, and its outlet end is connected to the sensing inlet of the water sensing mechanism through another pipe, thus forming a complete overflow detection path.

[0042] Preferably, the corner bracket 100 is further provided with a guide plate 300, and a flow channel 500 is formed inside the guide plate 300. The flow channel 500 has a water inlet 501 and a water outlet 502. One end of the water inlet 501 is used to connect to the inner tank 1000 of the dishwasher, and the water outlet 502 is connected to the overflow hole 1100. The core function of this embodiment is to achieve active collection and directional guidance of overflow water by adding the guide plate 300 and its internal flow channel 500, so as to ensure that it can enter the overflow hole 1100 more reliably.

[0043] A flow guide plate 300 is additionally provided on the corner bracket 100, and a complete flow channel 500 is formed inside the flow guide plate 300. This flow channel 500 has two functionally defined ports: its inlet 501 is configured to receive overflow water from the dishwasher inner tank 1000; its outlet 502 is directly aligned with and connected to the overflow hole 1100 on the corner bracket 100 body, thereby integrating the flow channel 500 and the overflow hole 1100 into a continuous fluid channel.

[0044] When the dishwasher inner tub 1000 overflows, the water first flows into the inlet 501 of the guide plate 300 and enters its internal flow channel 500. Subsequently, under the constraint and guidance of the flow channel 500, the water flows directionally to the outlet 502 of the flow channel 500. Finally, the water is smoothly discharged from the outlet 502 and directly enters the overflow hole 1100 connected to it, completing the entire process from collection to guidance to the next stage.

[0045] Preferably, a guide channel 600 is provided between the diversion plate 300 and the corner bracket 100. The guide channel 600 extends from the outside of the corner bracket 100 to the inside of the corner bracket 100, and its two ends are respectively connected to the outlet 502 of the flow channel 500 and the overflow hole 1100. The core function of this embodiment is to construct a smooth transition channel between the diversion plate 300 and the corner bracket 100 by setting the guide channel 600, so as to optimize the water flow path, prevent liquid overflow, and ensure that the water flow can enter the overflow hole 1100 from the diversion plate 300 without obstruction.

[0046] A guide channel 600 is provided in the connection area between the outlet 502 of the diversion plate 300 and the inlet of the overflow hole 1100 of the corner bracket 100. The guide channel 600 starts from the outer surface of the corner bracket 100 body and extends inward, and its two ends are configured to be seamlessly connected to the outlet 502 of the flow channel 500 of the diversion plate 300 and the inlet of the overflow hole 1100 on the corner bracket 100, respectively.

[0047] The water flowing out from the outlet 502 of the flow channel 500 of the diversion plate 300 will directly enter the guide channel 600. Under the constraint and guidance of the channel of the guide channel 600, the water flows smoothly along a predetermined path from the outside to the inside of the corner bracket 100, completing the transition from the diversion plate 300 to the body of the corner bracket 100, and is finally accurately guided to the inlet of the overflow hole 1100 to enter the subsequent process.

[0048] Preferably, the flow guide 600 is located on the top of the corner bracket 100. The core function of this embodiment is that by arranging the flow guide 600 on the top of the corner bracket 100, it can be directly and integrally completed during the casting or machining of the corner bracket 100, which effectively simplifies the manufacturing process and reduces the processing difficulty and production cost.

[0049] The guide channel 600 is directly formed on the top surface of the corner bracket 100 body. The guide channel 600 starts from the outer edge of the top of the corner bracket 100 and extends inward, with its two ends connected to the outlet 502 of the flow channel 500 of the guide plate 300 and the inlet of the overflow hole 1100, respectively.

[0050] The water flowing out of the diversion plate 300 flows naturally into the guide channel 600 located at the top of the corner bracket 100 under the action of gravity, and then flows inward and lower along the channel, so as to be efficiently and without stagnation guided to the inlet of the overflow hole 1100 below.

[0051] Preferably, the drainage plate 300 is detachably connected to the corner bracket 100. The core function of this embodiment is that, through the detachable connection structure, the drainage plate 300 can be easily separated from the corner bracket 100, so as to facilitate thorough cleaning or replacement.

[0052] The drain plate 300 and the corner bracket 100 are fixed to each other by a detachable connection. The contact interface between the drain plate 300 and the corner bracket 100 is configured to allow them to be separated and reassembled when needed without damaging the main structure of the corner bracket 100.

[0053] When cleaning or maintenance is required, the operator can directly remove the drain plate 300 from the corner bracket 100 to clean its internal flow channel 500 and outer surface without obstruction. After cleaning, the drain plate 300 can be reinstalled back onto the corner bracket 100 to restore the function of the entire overflow guide channel.

[0054] Preferably, the drainage plate 300 is provided with a plug-in portion, and the corner bracket 100 is provided with a plugged-in portion that mates with the plug-in portion, with the plug-in portion inserted downward into the plugged-in portion. The core function of this embodiment is to provide an intuitive, fast, and reliable connection and separation method through the downward insertion plug-in structure, thereby achieving the positioning and installation of the drainage plate 300.

[0055] A connector is formed at the bottom of the drain plate 300, and a connector is provided at the corresponding position on the corner bracket 100. The connector and the connector are matched in shape and size, so that the drain plate 300 can move vertically downward through its connector and finally insert into and engage with the connector of the corner bracket 100.

[0056] During installation, align the insertion part of the drain plate 300 with the insertion part of the corner bracket 100, and then press the drain plate 300 downward until the insertion part is fully inserted into the insertion part and reaches the predetermined position, thereby achieving the connection and fixation of the two; during disassembly, simply pull the drain plate 300 upward with force to disengage the insertion part from the insertion part.

[0057] Preferably, the corner bracket 100 is made of plastic. The core function of this embodiment is that by using plastic to manufacture the corner bracket 100, the component is made of lightweight material and mass-produced at low cost while ensuring structural strength.

[0058] The corner bracket 100 is integrally molded from plastic using an injection molding process. The properties of this material give it sufficient mechanical strength to be integrated into the base frame 400. At the same time, its internal overflow hole 1100, as well as the guide groove 600 that cooperates with the flow guide plate 300 and the connecting structure, can all be directly formed in this process.

[0059] The plastic material of the corner bracket 100 does not affect its overflow guidance function; the water still flows along the predetermined path through the overflow hole 1100 and related channels. Furthermore, this material has good corrosion resistance, effectively resisting the long-term erosion of the humid environment and detergent inside the dishwasher. Besides plastic, in specific implementations, the corner bracket 100 can also be made of composite materials or engineering alloys with similar mechanical and chemical properties.

[0060] It is understandable that this structural design, through the integrated layout of the corner bracket 100 and the connectivity of the overflow hole 1100, achieves the integrated function of overflow guidance and water detection within a limited space, improving the structural compactness and reliability of the dishwasher water monitoring system. The addition of a guide plate 300 with a flow channel 500 based on the corner bracket 100 enables the collection and guidance of overflow water; the guide channel 600 between the guide plate 300 and the corner bracket 100 further optimizes the water flow path, ensuring a smooth water transition; and the detachable connection design between the guide plate 300 and the corner bracket 100 greatly facilitates the installation of components and daily maintenance and cleaning.

[0061] A dishwasher base frame includes a dishwasher inner tub 1000, a base frame 400, and corner brackets 100. The dishwasher inner tub 1000 is provided with an overflow drain hole 700. The overflow drain hole 700, the flow channel 500 of the guide plate 300, and the overflow hole are sequentially connected along the overflow direction. The corner brackets 100 are formed at the corners of the base frame 400. The core function of this embodiment is that by integrating the corner brackets 100 as core functional components into the corners of the base frame 400, a compact, complete flow path, and reliable whole-machine-level overflow monitoring and management system is constructed.

[0062] Corner bracket 100, as a structural component, is fixedly formed at the corner of the base frame 400; the bottom or side wall of the dishwasher inner tub 1000 is provided with an overflow drain hole 700, the outlet of which corresponds in spatial position to the water inlet 501 of the guide plate 300 installed on the corner bracket 100, so that the overflow drain hole 700, the flow channel 500 inside the guide plate 300, and the overflow hole 1100 of the corner bracket 100 body are connected in sequence to form a closed guide path that starts from the inner tub and ends at the water sensing mechanism.

[0063] When the overflow water in the inner tank is discharged through its overflow drain hole 700, it flows sequentially through the flow channel 500 of the guide plate 300 for collection and primary guidance, and then enters the overflow hole 1100 of the corner code 100 for final delivery, finally reaching the selectively set water body sensing mechanism to trigger a response. This process utilizes the gravity flow characteristics of water, and the entire system requires no additional power, realizing automatic response from overflow occurrence to signal detection. The corner code 100 can be made of materials with sufficient structural strength and corrosion resistance, such as plastic, composite materials, or metal.

[0064] Preferably, the base frame of a dishwasher further includes a water collection tray and a water sensing mechanism; the water collection tray is located below the overflow hole 1100; the water sensing mechanism includes a control system and a water sensing sensor located on the water collection tray; the control system is electrically connected to the water sensing sensor and an electric drain valve.

[0065] The core function of this implementation method is to automatically detect and respond to overflowing water by adding a water sensing mechanism, so as to cut off the water source in time when an overflow occurs.

[0066] The water sensing mechanism consists of a water sensing sensor and a control system. The water sensing sensor is located in the flow path of the overflow hole of the corner code, and its signal output terminal is electrically connected to the control system through a wire. The control output terminal of the control system is connected to the electric drain valve on the water inlet passage of the dishwasher through a line, so as to open or close the inner tub of the dishwasher to drain water.

[0067] When overflowing water flows through the overflow hole and passes the water sensor, the water sensor is triggered and generates a detection signal. This signal is immediately sent to the control system. Upon receiving this signal, the control system generates a control command and sends it to the drain valve, which drives the drain valve to close, thereby cutting off the water supply to the dishwasher's inner tub and opening the electric valve to drain water properly.

[0068] In addition, the water sensing mechanism can also be implemented using a float-type liquid level switch, an infrared photoelectric sensor, or a capacitive proximity switch, which can detect the presence or flow of water.

[0069] It is understood that, based on the corner code 100 being formed at the corner of the base frame 400, the overflow monitoring function module is directly integrated into the structural component of the frame, realizing the integration of function and support structure, and greatly saving internal space; by setting the overflow drain hole 700 of the dishwasher inner tub 1000 at the corner of the inner tub and directly connecting it with the water inlet 501 of the diversion plate 300, the corner code 100 located at the corner of the base frame 400 corresponds to the water inlet 501 of the diversion plate 300 located at the corner of the inner tub, so that the water sensing mechanism inside the corner code 100 can sense and receive the overflow water in the first time; based on the layout of the overflow drain hole 700, the flow channel 500 of the diversion plate 300, and the overflow hole 1100 being connected sequentially along the overflow water direction, a complete and closed overflow path is constructed from the corner of the inner tub to the water sensing mechanism, ensuring that the overflow water can be reliably guided to the monitoring point.

[0070] Preferably, there are multiple corner brackets 100 with overflow holes 1100, located at both ends of the same side of the base frame 400. The core function of this embodiment is that by setting double corner brackets 100 overflow monitoring points on the same side, a redundant or partitioned monitoring layout is constructed, which significantly improves the reliability of overflow capture and the system fault tolerance.

[0071] On the same side of the base frame 400, multiple corner brackets 100 with overflow holes 1100 are integrated, with the multiple corner brackets 100 located at both ends of the side. Each corner bracket 100 is independently equipped with a complete guide plate 300, flow channel 500 and overflow hole 1100, and is connected to the overflow drain hole 700 in the corresponding area of ​​the dishwasher inner tub 1000, forming two sets of parallel overflow guidance and monitoring paths.

[0072] When the dishwasher inner tub 1000 overflows, the water flows into the overflow drainage system connected to either corner bracket 100, depending on its location. This design ensures that the overflow is quickly and effectively captured and guided, regardless of whether it occurs on the left, right, or center of the inner tub, avoiding blind spots or response delays that may exist with single-point monitoring. The corner bracket 100 can be made of materials with sufficient structural strength and corrosion resistance, such as plastic, composite materials, or metal.

[0073] Preferably, the corner bracket 100 is installed on the corresponding sheet metal part 200 by injection molding. The core function of this embodiment is to integrate the corner bracket 100 and the sheet metal part 200 into one unit through injection molding, achieving a firm physical connection and reliable sealing between the two, and simplifying the assembly process.

[0074] The corner bracket 100 is directly wrapped or embedded into the corresponding sheet metal part 200 by injection molding. During the injection molding process, the molten corner bracket 100 material flows and fills the pre-set holes or structural gaps on the sheet metal part 200. After cooling, a mechanical interlock is formed, so that the corner bracket 100 and the sheet metal part 200 are tightly combined into a whole component.

[0075] This injection-molded connection structure effectively resists vibration and impact during dishwasher operation, maintaining the stability of the connection between corner bracket 100 and sheet metal part 200, and ensuring that the structural integrity of the overflow channel is not affected. Besides injection molding, corner bracket 100 and sheet metal part 200 can also be fixed using other methods such as insert injection molding, snap-fit ​​connection, or screw fastening. Corner bracket 100 can be made of materials with sufficient structural strength and corrosion resistance, such as plastic, composite materials, or metal.

[0076] Preferably, the corner bracket 100 and the sheet metal part 200 are connected by a snap-fit ​​structure 800. The core function of this embodiment is to achieve quick connection and fixation between the corner bracket 100 and the sheet metal part 200 through the snap-fit ​​structure 800, without the need for additional fasteners, thus significantly improving assembly efficiency.

[0077] The corner bracket 100 is provided with a snap-fit ​​structure 800, and the corresponding position of the sheet metal part 200 is provided with a slot or edge that cooperates with the snap-fit ​​structure 800. The corner bracket 100 is elastically snapped into the slot of the sheet metal part 200 through its snap-fit ​​structure 800, so as to achieve a tight connection and relative fixation between the two.

[0078] The snap-fit ​​structure 800 can take various forms, such as cantilever snap-fit, ring snap-fit, or mushroom-head snap-fit. Besides snap-fit ​​connections, the corner bracket 100 and sheet metal part 200 can also be fixed using other methods such as screw fastening, riveting, or welding. The corner bracket 100 can be made of materials with sufficient structural strength and corrosion resistance, such as plastic, composite materials, or metal.

[0079] Preferably, the snap-fit ​​structure 800 includes a snap-fit ​​groove 801 on the sheet metal part 200 and a snap-fit ​​part 802 on the corner bracket 100; the snap-fit ​​groove 801 includes a slot 803 and a locking groove 804, and the slot 803 and the locking groove 804 belonging to the same snap-fit ​​groove 801 are interconnected; the snap-fit ​​part 802 slides into the slot 803 and then snaps into the locking groove 804. The core function of this embodiment is that, through the cooperation of the slot 803 sliding in and the locking groove 804 locking, a reliable connection with clear guidance, firm connection and anti-detachment function is achieved between the corner bracket 100 and the sheet metal part 200.

[0080] The snap-fit ​​structure 800 consists of two parts: one part is a snap-fit ​​groove 801 provided on the sheet metal part 200, which further includes a slot 803 for insertion and a locking groove 804 for final locking, and the slot 803 and the locking groove 804 belonging to the same snap-fit ​​groove 801 are interconnected; the other part is a snap-fit ​​part 802 provided on the corner bracket 100, which is designed in shape and size to slide into the slot 803 and finally snap into the locking groove 804.

[0081] During assembly, the snap-fit ​​part 802 of the corner bracket 100 is aligned with the slot 803 in the snap-fit ​​groove 801 of the sheet metal part 200 and slid horizontally into place. After moving to the predetermined position, the snap-fit ​​part 802 is moved from the slot 803 and locked in the locking groove 804 by vertical movement or rotation, thus completing the connection. Besides this sliding snap connection, the corner bracket 100 and the sheet metal part 200 can also be fixed using cantilever snaps, screw fastening, or other methods. The corner bracket 100 can be made of materials with sufficient structural strength and corrosion resistance, such as plastic, composite materials, or metal.
