Description

Technical Field

[0001] This invention relates to the field of mobile dishwasher technology, specifically to an anti-overflow, interconnected, safe mobile robotic dishwasher. Background Technology

[0002] Mobile robot dishwashers are a new type of home appliance that integrates functions such as autonomous movement, tableware storage, cleaning, and disinfection. Their core design concept is to use a mobile body to autonomously travel to the dining table and other scenarios to collect tableware after meals, and then work with a matching base station to complete water supply, power supply, drainage, and cleaning operations. Users do not need to manually move tableware, which greatly simplifies the post-meal housework process and meets the needs of modern families for convenient and automated housework. It has become one of the important development directions in the field of home service robots.

[0003] In the prior art, such as the novel dishwasher robot disclosed in Chinese Patent No. CN207024023U, a structure is adopted in which the robot body cooperates with a fixed base station. The body is equipped with an autonomous driving unit, a battery unit and a tableware storage container. The fixed base station can realize the charging and water supply and drainage functions of the body. In the split solution, the tableware storage container moves with the body to the base station and then connects to the cleaning device to complete the cleaning. In the integrated solution, the entire tableware cleaning unit is integrated into the body. After returning to the base station, water and electricity are connected and cleaning is performed, thus initially realizing the automation process of tableware collection, transportation and cleaning.

[0004] However, existing products still have significant shortcomings in terms of safety during use: on the one hand, the connection between the power supply and water supply of the device and the base station lacks a detection and linkage control mechanism, which may lead to the accidental activation of water and electricity supply when the connection is not fully in place, resulting in safety hazards such as water leakage and electric shock; on the other hand, the product does not have a dedicated anti-overflow protection structure. When water overflows due to abnormal water supply or equipment failure, the overflowing water lacks a dedicated collection and guidance path, which can easily cause indoor water accumulation. This can not only damage the floor, furniture and other home environment, but may also cause secondary electrical safety accidents as the accumulated water spreads to the base station power supply port or the electrical connection of the device, seriously affecting user safety and product reliability.

[0005] The above problems are worth solving. Summary of the Invention

[0006] To overcome the safety hazards of existing products lacking detection and linkage control for power and water supply connections and lacking anti-overflow protection structures, this invention provides an anti-overflow linkage safety mobile robotic dishwasher.

[0007] The technical solution of this invention is as follows:

[0008] An overflow-prevention, safety-linked mobile robotic dishwasher includes a mobile dishwasher and a multi-functional base station for power supply, water supply, and drainage. The mobile dishwasher is equipped with an electrical coupling female connector and a water receiving component. The multi-functional base station is equipped with an electrical coupling male connector and a water outlet component. The mobile dishwasher also includes an assembly-in-place trigger component and a drainage component. The multi-functional base station is also equipped with an assembly-in-place sensing component and a drainage collection box. When the mobile dishwasher moves to assemble with the multi-functional base station, the assembly-in-place trigger component, the assembly-in-place sensing component, the electrical coupling male and female connectors, the water receiving component and the water outlet component, the drainage component, and the drainage collection box simultaneously complete docking. The assembly-in-place trigger component and the assembly-in-place sensing component cooperate to issue a start command. The electrical coupling male connector starts and supplies power to the mobile dishwasher through the electrical coupling female connector. The water outlet component starts and supplies water to the mobile dishwasher through the water receiving component. The water receiving component is also equipped with an overflow-prevention drain outlet, and the multi-functional base station is equipped with an overflow-prevention collection box corresponding to the overflow-prevention drain outlet.

[0009] By adopting the above technical solutions, a synchronous linkage system integrating docking detection, power supply, water supply, and drainage was constructed. The coordinated assembly of the triggering and sensing components enabled accurate verification of the docking status. Power and water supply were only activated after all four components were fully docked, thus avoiding the risk of water leakage and electric shock caused by misalignment. The corresponding design of the overflow outlet and overflow collection box can quickly collect abnormally overflowing water, completely eliminating the risk of indoor water accumulation. At the same time, the entire docking and operation process can be completed without manual intervention, greatly improving the safety, automation, and reliability of the equipment.

[0010] As a preferred embodiment of the present invention, the assembly positioning trigger component is located on the back of the base of the mobile dishwasher, and includes an electromagnetic chuck protruding from the back of the base; the assembly positioning sensing component includes a spring magnet assembly, a switch push rod and a sensor switch, the electromagnetic chuck is magnetically connected to the spring magnet assembly, and the switch push rod pushes the trigger end of the sensor switch, and the sensor switch is electrically connected to the electronic control system of the dishwasher.

[0011] By adopting the above technical solution, after the inductive switch is triggered, it sends an assembly confirmation signal to the electronic control system. The electronic control system controls the electrical coupling male connector to conduct power supply according to the signal, and controls the water inlet solenoid valve of the water outlet component to open water supply, so as to realize the linkage locking of power supply, water supply and docking status.

[0012] Preferably, the spring-magnet assembly includes a compression spring and a magnet. The assembled sensing assembly has a slot for mounting the spring-magnet assembly. The slot is provided with a push rod mounting seat. The switch push rod passes through the push rod mounting seat from the inside to the outside, with its outer end connected to the magnet and its inner end pointing to the trigger end of the inductive switch. The compression spring is sleeved on the switch push rod and located between the push rod mounting seat and the magnet.

[0013] By adopting the above technical solution, the mobile dishwasher uses an electromagnetic chuck to magnetically connect to the base station with a magnet, improving the accuracy of the connection. During the connection process, the switch push rod moves towards the induction switch and compresses the spring. The spring's buffering effect can prevent damage to components caused by the connection impact, ensuring that the switch push rod smoothly pushes the trigger end of the induction switch. When the connection is broken, the spring resets, causing the switch push rod and magnet to return to their original positions, and the induction switch resets synchronously. This achieves accurate identification of the connection status and repeated reliable triggering, ensuring the stability of the linkage control.

[0014] As a preferred embodiment of the present invention, the water receiving assembly includes a water receiving tank, the water receiving tank having an inlet chamber and a drain chamber inside, the water outlet pipe of the water outlet assembly passing through the water receiving tank and located above the inlet chamber, and the inlet chamber and the drain chamber communicating above each other, so that when the water in the inlet chamber overflows, it flows into the drain chamber, and the overflow prevention outlet is located at the bottom of the drain chamber.

[0015] By adopting the above technical solution, the water tank is divided into an independent inlet chamber and an outlet chamber. The design of the two chambers being connected at the top creates a dedicated overflow guide path. When the inlet chamber overflows due to abnormal water supply or malfunction, the overflowing water can quickly flow into the outlet chamber and be discharged through the bottom overflow outlet, preventing the overflow water from spreading into the inside of the portable dishwasher or the ground around the base station. The dual-chamber structure clearly defines the functional areas for water storage and overflow guidance, ensuring stable storage of cleaning water and accurately guiding the overflow water out, effectively protecting the internal electrical components from water corrosion.

[0016] Optionally, the water tank is installed on the back of the portable dishwasher.

[0017] Furthermore, a float valve is provided in the water inlet chamber, and an elastic valve switch is provided at the end of the water outlet pipe. The elastic valve switch includes an elastic lever and a water-blocking valve core. One end of the elastic lever is located on one side of the float valve, and the other end abuts against the water-blocking valve core. When the float valve rises with the water level to press one end of the elastic lever, the other end pushes the water-blocking valve core to block the opening of the water outlet pipe.

[0018] By adopting the above technical solution, automatic flow restriction protection for water inlet is achieved. When the water level in the inlet chamber rises abnormally, the float valve rises with the water level and presses the elastic lever, thereby pushing the water-blocking valve core to block the water outlet and actively cut off the water inlet. This forms a dual anti-overflow mechanism of active supply cut-off and passive flow diversion with the passive anti-overflow mechanism of the drain chamber, further reducing the risk of water overflow.

[0019] Optionally, a liquid level sensor is installed inside the water inlet chamber. The liquid level sensor can collect water level data of the water inlet chamber in real time and transmit it to the electronic control system. When the water level is detected to be close to the overflow threshold, it can trigger the electronic control system to close the water inlet solenoid valve in advance, forming a dual protection of electronic early warning and mechanical backup with the mechanical cut-off of the float valve. The liquid level sensor can also provide real-time feedback on the water level status required for normal operation, ensuring that the water volume in the water inlet chamber meets the cleaning requirements.

[0020] Furthermore, the elastic valve switch also includes a valve seat and a tension spring. The water-blocking valve core includes a rod body and a sealing plug. The rod body is inserted into the valve seat. One end of the tension spring is connected to the inner wall of the valve seat, and the other end is connected to the rod body. The sealing plug is directly opposite the outlet of the water pipe. The elastic lever is hinged to the bottom of the valve seat, and a torsion spring is provided at the hinge. The other end of the elastic lever abuts against the side of the sealing plug near the valve seat.

[0021] By adopting the above technical solutions, the lifting spring can pull the water-blocking valve core back to its initial position after the water inlet stops and the float valve resets, ensuring smooth water flow from the outlet pipe during the next water supply; the torsion spring can drive the elastic lever to quickly reset, avoiding lever jamming and affecting subsequent use; the sealing plug precisely corresponds to the outlet pipe opening, improving the sealing effect during plugging and effectively preventing water leakage.

[0022] Preferably, the water tank opening is provided with a flip-up dust cover, which is hinged to the tank opening by a torsion spring.

[0023] By adopting the above technical solution, the flip-up dust cover can seal the water tank opening when not docked, preventing dust and foreign objects from entering the water tank, contaminating the incoming water, or damaging internal components. When the mobile dishwasher docks with the base station, the insertion of the water outlet pipe will automatically push the cover to flip open. After docking or disconnection, the torsion spring drives the cover to close automatically, achieving cleaning and protection without manual operation, thus improving the hygiene and ease of use of the equipment.

[0024] As a preferred embodiment of the present invention, the water outlet pipe of the water outlet assembly is equipped with a water inlet solenoid valve, which is electrically connected to the electronic control system of the dishwasher to receive commands to control the opening and closing of the water outlet pipe.

[0025] By adopting the above technical solution, the water inlet solenoid valve can respond to the assembly signal to start the water supply synchronously, and can also receive the command of the electrical control system to quickly cut off the water supply when the equipment malfunctions (such as overflow triggering), so as to achieve precise and intelligent control of the water supply, avoid safety problems caused by ineffective or abnormal water supply, and improve the automation and intelligence level of the equipment.

[0026] As a preferred embodiment of the present invention, the overflow prevention and drainage collection box is located inside the upper part of the power supply, water supply and drainage multi-functional base station, and the overflow inlet of the overflow prevention and drainage collection box faces upward and is directly opposite the overflow prevention and drainage outlet; the bottom of the overflow prevention and drainage collection box is connected to the drainage collection box through a water pipe.

[0027] By adopting the above technical solution, the overflow inlet of the overflow collection box is directly opposite the overflow outlet, ensuring 100% collection of overflow water and preventing overflow from spilling onto the ground; its connection design with the drainage collection box allows overflow water to be discharged together with washing wastewater, simplifying the structure while eliminating home damage and safety hazards caused by overflow.

[0028] As a preferred embodiment of the present invention, the bottom plate of the drainage collection box is inclined, and the drainage collection box is provided with a main drainage outlet on the lower side of the bottom plate, and the main drainage outlet is connected to an external drainage pipe.

[0029] By adopting the above technical solution, the inclined base plate uses gravity to guide wastewater to flow to the main drainage outlet, avoiding wastewater residue and sludge accumulation in the drainage collection box, reducing odor generation and bacterial growth, and improving the hygiene of the equipment.

[0030] As a preferred embodiment of the present invention, the drainage assembly includes a drain pipe extending out of the base housing of the mobile dishwasher, and the drainage collection box is located at the bottom of the power supply, water supply and drainage multi-functional base station, which has a drainage interface on the front of the base station housing; the drain pipe and the drainage interface are located at the same height.

[0031] By adopting the above technical solution, the design of the drainage pipe and drainage interface set at the same height and the drainage pipe extending out of the base shell ensures that the two can be quickly and accurately connected when connected synchronously, reducing wastewater leakage caused by misalignment of drainage channels and ensuring smooth drainage.

[0032] According to the above-described solution, the beneficial effects of this invention are as follows:

[0033] This invention constructs an integrated linkage mechanism for docking, triggering, power supply, and sewage discharge by adding an assembly-in-place trigger component and a drainage component to a mobile dishwasher, and an assembly-in-place sensing component and a drainage collection box to a multi-functional base station for power supply, water supply, and drainage. When the mobile dishwasher is assembled with the multi-functional base station, the assembly-in-place trigger component and sensing component, electrical coupling male and female connectors, water receiving component and water outlet component, and drainage component and drainage collection box are synchronously docked. The entire docking process can be completed without manual intervention, which significantly improves the automation level of equipment use and meets the core needs of convenient operation in home scenarios.

[0034] This invention forms a pre-locking safety mechanism for power and water supply by coordinating the assembled triggering component and the sensing component. This avoids safety hazards such as water leakage and electric shock caused by asynchronous power and water supply and docking due to the lack of docking status detection, and greatly improves the safety of equipment operation.

[0035] This invention achieves centralized collection and discharge of washing wastewater through direct connection between the drainage component and the drainage collection box, overcoming the leakage problem caused by the lack of a dedicated centralized design for wastewater discharge paths in existing products. The overflow prevention outlet added to the water receiving component works in conjunction with the overflow prevention collection box corresponding to the base station to form targeted overflow prevention protection. Even in the event of electrical system failure or water supply abnormality causing water to overflow, the overflowing water can be collected centrally through the overflow prevention channel, completely eliminating the risk of potential indoor water accumulation. It ensures safe use without on-site user supervision and further expands the applicability of the product in unattended scenarios. Attached Figure Description

[0056] Example 1

[0057] like Figures 1 to 4 As shown, a spill-proof, safety-linked mobile robotic dishwasher includes a mobile dishwasher 100 and a multi-functional base station 200 for power supply, water supply, and drainage. The mobile dishwasher 100 has a rectangular structure with a washing compartment on top. Its base 101 is equipped with an autonomous driving unit, which adopts a wheeled drive mechanism and is equipped with laser or infrared obstacle avoidance sensors. The internal components include an electronic control system and a battery unit. The electronic control system includes a PLC controller, which can integrate signal reception and command output functions. The battery unit is a rechargeable lithium battery that powers the autonomous driving unit.

[0058] The portable dishwasher 100 has an electrical coupling female connector 11 protruding from the lower back of the body. The electrical coupling female connector 11 has metal conductive contacts and is covered with an insulating protective sleeve. A water receiving component 2 is provided on the top back of the body, and a drain component 7 is provided on one side of the bottom back of the body. The vertical arrangement avoids mutual interference between the water receiving and drain components 7, and at the same time, it provides independent installation space for the electrical coupling female connector 11 in the middle. The drain component 7 includes at least a PVC drain pipe 71, which extends out of the body housing. An assembly-in-place trigger component 5 is provided at the center of the back of the base of the body. The assembly-in-place trigger component 5 includes at least an electromagnetic chuck.

[0059] The multi-functional power supply, water supply, and drainage base station 200 (hereinafter referred to as the base station) has a vertical structure and is fixedly installed in the corner of the kitchen wall. The lower front of the base station is equipped with an electrical coupling male connector 12 that is compatible with the electrical coupling female connector 11. The electrical coupling male connector 12 has a conductive probe or conductive spring block. The top front of the base station is equipped with a water outlet component 3 that corresponds to the dishwasher water inlet component 2. The water outlet component 3 includes at least a water outlet pipe 31. The end of the water outlet pipe 31 is equipped with a water inlet solenoid valve 33. The water inlet solenoid valve 33 and the dishwasher's electronic control system receive commands to control the opening and closing of the water outlet pipe 31. The end of the water outlet pipe 31 is connected to the household water supply pipe. The lower interior of the base station is equipped with a drainage collection box 8 that corresponds to the drainage component 7. The front of the base station housing is equipped with a drainage interface 81 that is compatible with the drainage pipe 71. The drainage interface 81 is connected to the drainage collection box 8. The drainage pipe 71 and the drainage interface 81 are located at the same height to ensure that they can be quickly and accurately connected when they are connected synchronously, reducing wastewater leakage caused by misalignment of the drainage channel and ensuring smooth drainage.

[0060] At the center of the front of the base station, there is an assembly positioning sensor 6 corresponding to the assembly positioning trigger component 5. When the mobile dishwasher 100 moves to assemble with the base station, the assembly positioning trigger component 5, the assembly positioning sensor 6, the male and female electrical coupling connectors 12 and 11, the water receiving component 2 and the water outlet component 3, the drainage component 7 and the drainage collection box 8 are simultaneously connected. The assembly positioning trigger component 5 and the assembly positioning sensor 6 work together to issue a start command. The male electrical coupling connector 12 starts and supplies power to the mobile dishwasher 100 through the female electrical coupling connector 11. The water outlet component 3 starts and supplies water to the mobile dishwasher 100 through the water receiving component 2.

[0061] like Figure 7 As shown, in this embodiment, the assembly-in-place sensing component 6 includes at least a spring-magnet assembly 61, a switch push rod 62, and a sensing switch 63. The sensing switch 63 is electrically connected to the dishwasher's electronic control system. After the mobile dishwasher 100 is assembled with the power supply, water supply, and drainage multi-functional base station 200, the electromagnetic chuck is magnetically connected to the spring-magnet assembly 61, and the trigger end of the sensing switch 63 is pushed by the switch push rod 62. After the sensing switch 63 is triggered, it sends an assembly-in-place confirmation signal to the electronic control system. The electronic control system controls the electrical coupling male connector 12 to conduct power supply according to the signal and controls the water inlet solenoid valve 33 of the water outlet component 3 to open the water supply, realizing the linkage and locking of power supply, water supply, and docking status. The water inlet solenoid valve 33 can respond to the assembly-in-place signal to realize synchronous water supply start-up, and can also receive the electronic control system command to quickly cut off the water supply when the equipment malfunctions (such as anti-overflow triggering), realizing precise and intelligent control of water supply, avoiding safety problems caused by ineffective or abnormal water supply, and improving the automation and intelligence level of the equipment.

[0062] The spring-magnet assembly 61 includes a compression spring 611 and a magnet 612. The assembled sensing assembly 6 has a slot for mounting the spring-magnet assembly 61. This slot is equipped with a push rod mounting seat 64. The switch push rod 62 passes through the push rod mounting seat 64 from the inside to the outside, with its outer end connected to the magnet 612 and its inner end pointing towards the trigger end of the inductive switch 63. The compression spring 611 is sleeved on the switch push rod 62 and located between the push rod mounting seat 64 and the magnet 612. During the docking process of the assembled trigger assembly 5 and the assembled sensing assembly 6, the switch push rod 62 moves towards the inductive switch 63 and compresses the spring 611. The spring's buffering effect can avoid damage to the components caused by docking impact, ensuring that the switch push rod 62 smoothly pushes the trigger end of the inductive switch 63. When the docking is disengaged, the spring resets, causing the switch push rod 62 and the magnet 612 to return to their original positions, and the inductive switch 63 resets synchronously. This achieves accurate identification of the docking state and repeated reliable triggering, ensuring the stability of the linkage control.

[0063] The above technical solution constructs a synchronous linkage system integrating docking detection, power supply, water supply and drainage. The coordinated operation of the assembled trigger component 5 and the sensing component enables accurate verification of the docking status. Power supply and water supply are only activated after all four components are fully docked, thus avoiding the risk of water leakage and electric shock caused by docking misalignment from the source.

[0064] The water receiving component 2 of the portable dishwasher 100 is also equipped with an overflow prevention outlet 213; an overflow prevention collection box 4 corresponding to the overflow prevention outlet 213 is provided on the upper part of the base station, which can quickly collect abnormally overflowing water, completely eliminate the risk of indoor water accumulation, and complete the entire process docking and operation without manual intervention, which greatly improves the safety, automation and reliability of the equipment.

[0065] In this embodiment, the water receiving assembly 2 includes a water receiving tank 21. The interior of the water receiving tank 21 is divided into an inlet chamber 211 and a drain chamber 212 by a longitudinal partition 210. The top of the longitudinal partition 210 is lower than the opening of the water receiving tank 21, allowing the two chambers to communicate from above. The outlet pipe 31 of the water outlet assembly 3 passes through the water receiving tank 21 and faces the top of the inlet chamber 211, ensuring a smooth water flow. Water is then supplied to the dishwasher through the inlet 2110 of the inlet chamber 211. The overflow drain outlet 213 is located at the bottom of the drain chamber 212, directly opposite the overflow inlet 41 of the overflow collection box 4, ensuring that overflow water falls directly into the overflow collection box 4, preventing overflow water from spilling onto the ground. The bottom of the overflow collection box 4 is connected to the drain collection box 8 via a PVC water pipe, allowing overflow water to flow into the drain collection box 8 for unified discharge. This simplifies the structure while eliminating home damage and safety hazards caused by overflow water.

[0066] The process of connecting the portable dishwasher 100 and the multi-functional base station 200 for power supply, water supply, and drainage in this embodiment is as follows:

[0067] S1. Docking preparation: After the user finishes their meal, the mobile dishwasher 100 starts up to receive the tableware and then moves to the base station, aligning the back of the machine with the front of the base station. During this time, the autonomous driving unit travels along a preset path under the guidance of the positioning module and calibrates its position using laser or infrared sensors.

[0068] S2. Synchronous docking: The mobile dishwasher 100 slowly approaches the base station. First, the electromagnetic chuck of the assembly-in-place trigger component 5 is energized, generating a magnetic attraction force with the spring magnet component 61 of the base station (the adsorption surface of the magnet 612 is parallel to the electromagnetic chuck), which drives the body to further precisely fit the base station. During this process, the female and male electrical coupling connectors 11 and 12 make synchronous contact, the opening of the water tank 21 of the water receiving component 2 is aligned with the water outlet pipe 31 (i.e., the water outlet pipe 31 is inserted into the opening of the water tank 21), and the drain pipe 71 of the drain component 7 is inserted into the drain interface 81, realizing the synchronous docking of the assembly-in-place trigger component 5 with the sensing component, the female and male electrical coupling connectors, the water receiving component 2 with the water outlet component 3, and the drain component 7 with the drain collection box 8.

[0069] S3, Linked Power Supply: After docking, the electromagnetic chuck pushes the spring magnet assembly 61 and the switch push rod 62 into the base station through magnetic attraction. The front end of the switch push rod 62 touches the trigger end of the induction switch 63, and the induction switch 63 transmits the "assembled in place" electrical signal to the electronic control system. After receiving the signal, the electronic control system outputs a command to control the electrical coupling male connector 12 to conduct (connect to the household 220V power supply to power the cleaning unit of the portable dishwasher 100), and at the same time controls the water inlet solenoid valve 33 to open (household tap water is injected into the water inlet chamber 211 through the water outlet pipe 31).

[0070] S4. Cleaning and Drainage: The cleaning unit of the portable dishwasher 100 is started, and the water in the water inlet chamber 211 is used to clean the dishes; the washing wastewater flows into the drain collection box 8 through the drain pipe 71, and then is discharged through the household drain pipe 71.

[0071] S5. Operation complete: After cleaning is completed, the electronic control system controls the water inlet solenoid valve 33 to close, the electrical coupling male connector 12 to be de-energized, the electromagnetic chuck to be de-energized and demagnetized, and the spring magnet assembly 61 to be reset under the action of the spring force, which drives the switch push rod 62 to separate from the induction switch 63; the mobile dishwasher 100 drives away from the base station through the autonomous driving unit, completing one operation cycle.

[0072] During steps S3 and S4 above, the overflow protection is activated: if the water inlet solenoid valve 33 fails to close, causing the water level in the water inlet chamber 211 to rise continuously, when the water level exceeds the top of the longitudinal partition 210, the overflow water will automatically flow into the drain chamber 212, and then fall into the overflow drain collection box 4 through the overflow drain outlet 213, and finally flow into the drainage collection box 8 for discharge, thus preventing overflow water from leaking to the machine body or the ground.

[0073] As can be seen, this invention, by adding an assembly-in-place trigger component 5 and a drainage component 7 to the mobile dishwasher 100, and adding an assembly-in-place sensing component 6 and a drainage collection box 8 to the power supply, water supply, and drainage multi-functional base station 200, constructs an integrated linkage mechanism for docking, triggering, power supply, and sewage discharge. When the mobile dishwasher 100 is assembled with the multi-functional base station, the assembly-in-place trigger component 5 and the sensing component, the electrical coupling male and female connectors, the water receiving component 2 and the water outlet component 3, and the drainage component 7 and the drainage collection box 8 are simultaneously docked, completing the entire docking process without manual intervention. This significantly improves the automation level of equipment use and meets the core need for convenient operation in home scenarios. Furthermore, this invention, through the coordinated triggering of the assembly-in-place trigger component 5 and the sensing component, forms a pre-locking safety mechanism for power and water supply, avoiding the need for docking due to lack of connection. The invention significantly improves the safety of equipment operation by eliminating potential safety hazards such as water leakage and electric shock caused by asynchronous power and water supply and connection. The invention achieves centralized collection and discharge of washing wastewater through direct connection between the drainage component 7 and the drainage collection box 8, overcoming the leakage problem caused by the lack of a dedicated centralized design for wastewater discharge path in existing products. The overflow prevention outlet 213 added to the water receiving component 2 works in conjunction with the overflow prevention collection box 4 corresponding to the base station to form targeted overflow prevention protection. Even in the event of electrical system failure or water supply abnormality causing water to overflow, the overflowing water can be collected centrally through the overflow prevention channel, completely eliminating the risk of indoor water accumulation. It can ensure safe use without on-site user supervision, further expanding the applicability of the product in unattended scenarios.

[0074] Example 2

[0075] like Figure 5 and Figure 6 As shown, an anti-overflow linkage safety mobile robotic dishwasher, based on Embodiment 1, optimizes the anti-overflow mechanism by adding a float valve and a flexible valve switch, forming a dual anti-overflow protection of active supply cut-off and passive flow diversion, further reducing the risk of overflow. Its technical solution, based on Embodiment 1, is supplemented as follows:

[0076] A float valve 22 is provided in the water inlet chamber 211, and an elastic valve switch 32 is provided at the end of the water outlet pipe 31. Specifically, it is fixed by a mounting base 310. The elastic valve switch 32 includes a valve seat 320, an elastic lever 321, a water-blocking valve core 322, a tension spring 323, and a torsion spring. The valve seat 320 has a cylindrical structure and is fixedly sleeved on the outside of the end of the water outlet pipe 31. A hinge seat is provided at the bottom of the valve seat 320. The middle part of the elastic lever 321 is installed on the hinge seat through a hinge shaft. A torsion spring is sleeved on the hinge shaft. One end of the torsion spring is fixed to the hinge seat, and the other end is fixed to the elastic lever 321. In the natural state, one end of the elastic lever 321 tilts downward.

[0077] In this embodiment, the water-blocking valve core 322 includes a rod body 3221 and a sealing plug 3222. The rod body 3221 is inserted into the valve seat 320. A tension spring 323 is sleeved on the outside of the rod body 3221, with one end fixed to the inner wall of the valve seat 320 and the other end fixed to the middle of the rod body 3221. The sealing plug 3222 is directly opposite the outlet of the water pipe 31. In its natural state, the tension spring 323 pulls the sealing plug 3222 away from the outlet of the water pipe 31 to ensure smooth water flow. The elastic lever 321 with one end tilted downward is located directly above the float valve 22, and the other end abuts against the side of the sealing plug 3222 near the valve seat 320.

[0078] The action procedure for triggering the mechanical water supply interruption protection in this embodiment is as follows:

[0079] During the water filling process of the inlet chamber 211, the float valve 22 rises synchronously with the water level. When an abnormal situation occurs, the water level approaches the top of the inlet chamber 211 and reaches the overflow threshold, and water supply continues. Excess water flows from the inlet chamber 211 to the drain chamber 212 for discharge. At this time, the top of the float valve 22 contacts one end of the elastic lever 321. The float valve 22 presses one end of the elastic lever 321, and the elastic lever 321 rotates around the hinge axis. The other end pushes the water-blocking valve core 322 to move along the guide hole to the outlet pipe 31 until the sealing plug 322 completely fits the outlet pipe 31, thereby sealing the pipe and actively cutting off the water supply. After the abnormal situation is resolved and the normal state is restored, the float valve 22 sinks with the water level, and the pressure on the elastic lever 321 disappears; the elastic lever 321 resets under the elastic force of the torsion spring, the water-blocking valve core 322 resets under the tension of the lifting spring 323, and the sealing plug 3222 separates from the outlet pipe 31, preparing for the next water supply.

[0080] This embodiment implements automatic flow limiting protection for water inlet. When the water level in the inlet chamber 211 rises abnormally, the float valve 22 rises with the water level and presses against the elastic lever 321, thereby pushing the water-blocking valve core 322 to block the outlet pipe 31. The sealing plug 3222 precisely aligns with the outlet pipe 31, improving the sealing effect during blocking and actively cutting off the water inlet. This, together with the passive overflow prevention of the drain chamber 212, forms a dual overflow prevention mechanism of active supply cut-off and passive flow diversion. The tension spring 323 can pull the water-blocking valve core 322 back to its initial position after the water inlet stops and the float valve 22 resets, ensuring smooth water flow from the outlet pipe 31 during the next water supply. This effectively prevents water leakage.

[0081] Example 3

[0082] An anti-overflow safety mobile robotic dishwasher, based on Embodiment 2, adds a liquid level sensor to achieve precise water level control. Its technical solution, based on Embodiment 2, is supplemented as follows:

[0083] The inlet chamber 211 is equipped with a liquid level sensor, which can collect water level data in the inlet chamber 211 in real time and transmit it to the electronic control system. It can provide real-time feedback on the water level status required for normal operation, ensuring that the water volume in the inlet chamber 211 meets the cleaning requirements. In addition, when the water level is detected to be close to the overflow threshold, the electronic control system can be triggered in advance to close the inlet solenoid valve 33, forming a dual protection of electronic early warning and mechanical backup with the mechanical cut-off of the float valve 22.

[0084] Example 4

[0085] like Figure 4 As shown, an anti-overflow linkage safety mobile robotic dishwasher, based on embodiments one to three, features structural optimization of the drain collection box 8. Specifically, the bottom plate of the drain collection box 8 is inclined, and a main drain outlet 82 is provided on the lower side of the bottom plate. The main drain outlet 82 is connected to an external drain pipe 71 (i.e., household drain pipe 71). The inclined bottom plate uses gravity to guide wastewater to flow towards the main drain outlet 82, preventing wastewater from remaining and accumulating in the drain collection box 8, reducing odor generation and bacterial growth, and improving the hygiene of the equipment.

[0086] Example 5

[0087] like Figure 3 As shown, an anti-overflow linkage safety mobile robot dishwasher, based on embodiments one to four, optimizes the position and structure of the water tank 21. Specifically, the water tank 21 is installed on the back of the mobile dishwasher 100, without occupying the core tableware storage area or washing unit space inside the machine, ensuring that the tableware loading capacity and washing function are not affected. At the same time, the back installation makes the weight of the water tank 21 evenly distributed with the center of gravity of the machine, ensuring stability during movement. Moreover, the back position precisely corresponds to the front docking area of ​​the power supply, water outlet and drainage multi-functional base station 200, shortening the alignment path of the water receiving component 2 and the water outlet component 3, reducing docking errors, and improving the sealing and stability of the water supply docking.

[0088] The water tank 21 has a flip-up dust cover 214 at its opening, which is hinged to the opening by a torsion spring. In the non-connected state, the torsion spring drives the dust cover to tightly close the opening of the water tank 21, effectively preventing kitchen fumes, dust, food scraps, and other contaminants from entering the inlet chamber 211 and outlet chamber 212, thus avoiding contamination of the cleaning water and ensuring smooth water flow and hygienic cleaning. During connection, the outlet pipe 31 naturally pushes the dust cover to flip open along the hinge axis during insertion, requiring no additional operation. After disconnection, the torsion spring immediately drives the dust cover to automatically close, conforming to the overall automation logic of the solution and requiring no manual intervention.

[0089] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
