To achieve wastewater recycling and improve environmental performance and efficiency, the wastewater collected by the cleaning robot is typically collected at a base station.

Detailed Implementation

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] Currently, the method used by cleaning equipment to achieve wastewater recycling involves: collecting wastewater from cleaning robots at a base station, heating and evaporating the collected wastewater to generate steam, condensing the steam in an evaporator of a compression system, and then pumping the condensate back into the base station's clean water system for reuse. The entire compressor system is complex, space-consuming, and costly. Due to its complexity, it is difficult to achieve a complete seal in the piping system, causing steam to directly connect with the outside air after passing through the evaporator, resulting in leakage of condensed gas. The amount of condensed water is far less than the amount of wastewater evaporated, leading to a low wastewater recycling rate. Furthermore, directly heating the wastewater container with a heating plate results in uneven steam flow and dead zones, leading to low condensation efficiency.

[0047] like Figure 1As shown in the figure, this application discloses a sewage recycling device, which includes a sewage holding device 1, a heating device 2, a condensation module 3, a recycling storage device, and a circulating fan 4; the sewage holding device 1 includes an air inlet 5 and a water vapor outlet 6, the condensation module 3 includes a water vapor inlet 7, a cooling device 8, and a condensate outlet 9, and the circulating fan 4 includes an air outlet 10.

[0048] The heating device 2 is located at the bottom of the sewage containing device 1;

[0049] The steam inlet 7 and the condensate outlet 9 are respectively located at both ends of the cooling device 8, and the end of the cooling device 8 near the condensate outlet 9 is lower than the end of the cooling device 8 near the steam inlet 7.

[0050] The air inlet 5 is connected to the air outlet 10, and the water vapor outlet 6 is connected to the water vapor inlet 7.

[0051] The condensate outlet 9 is connected to the recycling and storage device;

[0052] The circulating fan 4 is fixedly connected to the condensation module 3 and is internally interconnected.

[0053] Optionally, such as Figure 1 As shown, the sewage containing device 1 is a sewage tank used to store sewage. A heating device 2 is located at the bottom of the sewage tank; the heating device 2 can be a heating plate.

[0054] Optionally, such as Figure 1 As shown, the wastewater recycling device includes a wastewater holding device 1, a heating device 2, a condensation module 3, a recycling storage device, and a circulating fan 4 forming a closed space.

[0055] Optionally, such as Figure 1 As shown, the sewage containing device 1 has a heating device 2 at its bottom. The heating device 2 heats and evaporates the sewage in the sewage containing device 1, generating a large amount of water vapor. Under the action of the circulating fan 4, the water vapor circulates within the sealed space.

[0056] Optionally, such as Figure 1 As shown, when water vapor passes through the condensation module 3, the temperature drops rapidly, causing the water vapor to condense into water. Since the condensation module 3 is tilted downwards along the steam direction, the condensate collects under gravity and flows to the condensate outlet 9. The condensate outlet 9 is connected to the recycling and storage device, which pumps the condensate back into the storage device for storage. Specifically, the recycling and storage device is a base station clean water tank, where the condensate is pumped back for recycling.

[0057] Optionally, the wastewater containing device includes a wastewater container 11 and an air guiding structure 12.

[0058] The air guide structure 12 is disposed in the cavity of the sewage container 11 and is fixedly connected to the sewage container 11. The air guide structure 12 is used to realize the directional movement of water vapor in the sewage container 11.

[0059] Optionally, such as Figure 1 As shown, the air guide structure 12 is provided inside the sewage container 11. The air guide structure is used to make water vapor inside the sewage container 11 move in the guiding direction, and the movement trajectory covers all the space inside the sewage container 11.

[0060] Optionally, such as Figure 2 As shown, the air guide structure 12 is an air guide plate. After the water vapor passes through the condensation module 3, under the action of the circulating fan 4, the condensed air returns to the sewage container 11 through the pipeline to carry away the water vapor. At this time, under the action of the air guide plate, the air flows spirally and orderly from the center of the sewage container 11 along the direction of the air guide structure 12 to the outer edge of the sewage container 11.

[0061] In this implementation, by designing an air guiding structure inside the sewage container, water vapor inside the sewage container moves in a certain direction, and the movement trajectory covers all the space inside the sewage container, so that the heated water vapor is carried out by the wind without dead angles, thereby improving the sewage recovery rate.

[0062] Optionally, the air guiding structure 12 includes air guiding ribs 13, which are spiral structures.

[0063] The starting end of the air guide rib 13 is located close to the center of the cavity, and the end of the air guide rib 13 is fixedly connected to the side of the cavity.

[0064] The air guide ribs 13 are fixedly connected to the first surface and the second surface of the cavity, respectively, and the first surface and the second surface are arranged opposite each other in the vertical direction.

[0065] Optionally, the space between the air guide rib 13 and the cavity forms an air guide groove 14;

[0066] The air guide trough 14 includes a first slot 15 and a second slot 16. The first slot 15 is located at the starting end of the air guide rib 13 and is fixedly connected to and communicates with the air inlet 5 of the sewage containing device 1. The second slot 16 is located at the end of the air guide rib 13 and is fixedly connected to and communicates with the water vapor outlet 6.

[0067] The air guide groove 14 is used to guide the water vapor in the cavity to the water vapor outlet 6.

[0068] Optionally, such as Figure 2 As shown, the air guide rib 13 has a spiral structure. Under the action of the air guide rib 13, the air flows spirally and orderly from the center of the sewage container 11 along the direction of the air guide rib 13 to the outer edge of the sewage container 11. During the entire flow process, the water vapor is also carried away, so that the heated water vapor is carried out by the air without dead angles.

[0069] Optionally, such as Figure 1 and Figure 2 As shown, under the action of the circulating fan 4, the condensed air flows from the outlet 11 of the circulating fan 4 through the pipe to the inlet 5, flows into the first slot 15 from the inlet 5, and carries the water vapor in the sewage container 11. It spirals and flows orderly along the direction of the guide rib 13 towards the outer edge of the sewage container 11, passes through the second slot 16 to the water vapor outlet 6, and the air carrying water vapor flows through the water vapor outlet 6 into the water vapor inlet 7, and reaches the cooling device 8. After being cooled by the cooling device 8, condensate is obtained, and it is drawn back from the condensate outlet 9 to the recovery and storage device.

[0070] In this implementation, an air guide structure is designed inside the sewage container to make the steam inside the sewage container move in a certain direction. Since the air inside the sewage container can flow through, it can efficiently remove the steam inside the sewage container, improve the sewage recycling efficiency, and under the guidance of the air guide channel, the internal airflow flows outward in an orderly manner, avoiding the problem of poor flow caused by disordered turbulence inside.

[0071] Optionally, such as Figure 3 As shown, the cooling device 8 includes a support structure 17, an air inlet plate 18, and steam guide holes 19.

[0072] The condensate outlet 9 is located on the outer shell of the support structure 17;

[0073] The steam guide hole 19 is disposed through the interior of the support structure 17. One end of the steam guide hole 19 is fixedly connected to and communicates with the steam inlet 7, and the other end of the steam guide hole 19 is close to the condensate outlet 9. The steam guide hole 19 is set at a preset angle to the horizontal direction so that the condensate flows into the recovery storage device through the condensate outlet 9.

[0074] The air inlet plate 18 is disposed on the surface of the support structure 17, and the air inlet plate 18 is used to dissipate heat from the steam guide hole 19.

[0075] Optionally, the cooling device 8 further includes a cooling fan 20.

[0076] The cooling fan 20 is positioned at a preset fan location on the surface of the support structure 17. The airflow direction of the cooling fan 20 is perpendicular to the airflow direction of the water vapor in the steam guide hole 19. The cooling fan 20 is used to cool the water vapor in the steam guide hole 19.

[0077] Optionally, the air inlet plate 18 is provided with a plurality of heat sinks 21, which are used to dissipate the heat of the air inlet plate 18.

[0078] Optionally, such as Figure 3 As shown, the support structure 17 has multiple steam guide holes 19 extending through it. These steam guide holes 19 are set at a predetermined angle to the horizontal direction and are inclined towards the condensate outlet 9. Under the operation of the circulating fan 4, water vapor passes through the steam guide holes 19.

[0079] Optionally, such as Figure 3 and Figure 4 As shown, the surface of the support structure 17 is provided with the air inlet plate 18, which is used to dissipate heat from the water vapor inside the steam guide hole 19.

[0080] Optionally, such as Figure 4 As shown, the condensate outlet 9 is located on the outer shell of the support structure 17.

[0081] Optionally, such as Figure 3 and Figure 4 As shown, the air inlet plate 18 is provided with a plurality of heat sinks 21. The heat sinks 21 can be heat dissipation fins. The heat sinks 21 are used to enhance heat transfer. The heat sinks 21 have good and stable heat transfer performance and low air resistance. Water vapor passes through the steam guide hole 19. Heat is transferred through the plurality of heat sinks 21 provided on the air inlet plate 18 to the air around the heat sinks 21, thereby achieving the effect of heat dissipation.

[0082] In this implementation, the condensation module draws external air to rapidly cool the steam passing through the steam inlet, enabling the recycling of condensed wastewater. Since the steam inlet and heat sink form the condensation structure, and an external cooling fan drives airflow for cooling, no external gas piping is required. The entire structure is easily sealed, ensuring smooth operation of the circulation system and preventing water vapor leakage. Furthermore, production and assembly are simple and inexpensive. This simple structure, replacing the condensation system of a compressor, significantly improves efficiency, reduces costs, and saves space.

[0083] Optionally, such as Figure 4As shown, the wastewater recycling device also includes a humidity detection device 22.

[0084] The steam outlet 6 and the steam inlet 7 are connected by a pipe;

[0085] The humidity detection device 22 is installed in the pipe between the water vapor outlet 6 and the water vapor inlet 7, and the humidity detection device 22 is used to detect the humidity of the internal environment of the wastewater recycling device.

[0086] Optionally, such as Figure 4 As shown, the humidity detection device 22 is installed in the pipe between the water vapor outlet 6 and the water vapor inlet 7. The humidity detection device 22 is used to detect the humidity of the internal environment of the wastewater recycling device and determine whether the internal wastewater has been completely evaporated based on the humidity detection result.

[0087] Optionally, if the humidity detection result indicates that the humidity of the internal environment of the wastewater recovery device is less than a preset humidity threshold, it is determined that the wastewater inside the wastewater recovery device has been completely evaporated, condensed, and recovered.

[0088] In this implementation, the entire pipeline module is connected using a sealed structure, and the circulating fan is installed inside the pipeline, preventing internal gas leakage. Therefore, the amount of condensate produced is directly proportional to the amount of wastewater evaporated. By placing a humidity sensor inside the pipeline, it is possible to accurately determine whether the internal wastewater has completely evaporated. Once the wastewater has completely evaporated, the heating device is turned off to avoid energy waste and improve the efficiency of wastewater recycling.

[0089] Optionally, such as Figure 5 As shown, a blade 23 is provided at a preset position on the outer edge of the air guide structure 12. Since sludge will exist at the bottom of the cavity of the sewage container 11 after the sewage in the sewage container 11 has evaporated, the blade 23 is used to clean the sludge.

[0090] Optionally, such as Figure 5 As shown, after the sewage in the sewage container 11 has evaporated, the air guide structure 12 is rotated, causing the blade 23 to rotate on the lower surface of the cavity of the sewage container 11, thus crushing the sludge on the lower surface of the cavity into dry waste. The dust collection fan is then activated to recycle the dry waste. Specifically, the dust collection fan is connected to the cavity of the sewage container 11.

[0092] S101, in response to the object's start command for the wastewater recycling device, the wastewater holding device 1 is heated based on the heating device 2 so that the water in the wastewater holding device 1 is converted into water vapor.

[0093] S103, the circulating fan 4 guides the water vapor in the sewage containing device 1 to the condensation module 3 so that the condensation module 3 cools the water vapor to obtain condensate.

[0094] S105, the condensate is stored in a recycling storage device to achieve wastewater recycling.

[0097] The cooling module 702 is used to guide water vapor in the sewage containing device 1 to the condensation module 3 based on the circulating fan 4, so that the condensation module 3 cools the water vapor to obtain condensate.
