Description

Technical Field

[0001] This invention relates to the field of cleaning equipment, and in particular to a highly efficient dust collection method for a cleaning robot and the cleaning robot itself. Background Technology

[0002] The cleaning robot can automatically clean the environment. The current cleaning robot system consists of a cleaning host and a base station. When working, the cleaning host leaves the base station to sweep and / or mop the floor, collects the garbage into its own dust collection chamber, and then returns to the base station. The base station collects the garbage in the host's dust collection chamber into the base station's dust collection chamber.

[0003] After the cleaning unit returns to the base station, the base station connects to the cleaning unit's dust collection chamber via the base station's dust collection port. The base station then activates its built-in dust collection fan to suck up debris from the cleaning unit through the dust collection port and store it in the base station's dust collection chamber, thus achieving the dust collection function. It's generally believed that a larger airflow is better for dust collection, as a larger airflow means stronger suction, allowing for faster and more thorough collection of debris from the cleaning unit into the base station's dust collection chamber. However, everyday debris is often messy, including hair, sunflower seed shells, peanut shells, and thread ends. When sucked into the dust collection chamber by the cleaning unit, it is often compressed into a clump by the suction. Therefore, if there is a lot of debris in the dust collection chamber, the debris clump will be relatively large. During the base station's dust collection process, the base station fan, using strong suction, may cause the debris to completely block narrow channels such as the roller brush opening and dust box opening, resulting in a low dust collection rate. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a highly efficient dust collection method for a cleaning robot and a cleaning robot in view of the above-mentioned defects in the related technologies.

[0005] The technical solution adopted by this invention to solve its technical problem includes: providing a high-efficiency dust collection method for a cleaning robot, wherein the cleaning robot includes a base station and a cleaning host for cleaning, the cleaning host is provided with a host fan and a host dust collection chamber, the cleaning host is provided with a host dust collection port communicating with the host dust collection chamber, the base station is provided with a base station fan and a base station dust collection chamber, the base station is provided with a base station dust collection port communicating with the base station dust collection chamber, and the method includes the following steps:

[0006] S1: The cleaning host leaves the base station to perform cleaning, and the host fan absorbs the cleaned garbage into the host dust collection chamber;

[0007] S2: The cleaning host returns to the base station;

[0008] S3: The base station dust collection chamber is connected to the host dust collection chamber through the base station dust collection port. The base station fan draws air from the host dust collection chamber through the base station dust collection port and the host dust collection port, generating base station airflow on the debris in the host dust collection chamber. The host fan is connected to the host dust collection chamber and generates host airflow on the debris in the host dust collection chamber. The host fan draws air from the host dust collection chamber, and the host airflow is suction force. The direction of the base station airflow is opposite to the direction of the host airflow. When the host fan draws air from the host dust collection chamber, the base station airflow is greater than the host airflow. The base station airflow and the host airflow together form a total suction force on the debris in the host dust collection chamber. The debris in the host dust collection chamber enters the base station dust collection chamber under the action of the total suction force. Changing the magnitude of the base station airflow and / or the host airflow changes the magnitude of the total suction force, sending debris with different characteristics from the host dust collection chamber to the base station dust collection chamber.

[0009] Preferably, step S3 includes: the host fan blowing air into the host dust collection chamber, the host fan blowing air is a blowing force, and the direction of the base station fan is the same as the direction of the host fan.

[0010] Preferably, in step S3, when the host fan blows air into the host dust collection chamber, the host airflow is less than, equal to or greater than the base station airflow.

[0011] Preferably, in step S3, the main unit fan first draws air from the main unit dust collection chamber, and the main unit airflow gradually decreases. Then, the main unit fan blows air into the main unit dust collection chamber, and the main unit airflow gradually increases.

[0012] Preferably, during the process of the total suction force acting on the dust collection chamber of the main unit, the total suction force gradually increases.

[0013] Preferably, the main fan and / or the base station fan are provided with at least two wind speed settings.

[0014] Preferably, the main fan has at least two wind speed settings, and the wind speed of the base station fan is fixed; or, the wind speed of the main fan is fixed, and the base station fan has at least two wind speed settings; or, both the main fan and the base station fan have at least two wind speed settings.

[0015] Preferably, step S3 includes the following steps:

[0016] S31: Based on the characteristics of the waste, the waste is divided into at least two categories. Each category of waste is assigned a waste coefficient, and each waste coefficient corresponds to a dust collection coefficient. Each dust collection coefficient includes the operating speed and operating time of the host fan and / or the base station fan.

[0017] S32: The cleaning host selects one of the dust collection coefficients according to a preset priority order;

[0018] S33: The cleaning host determines the corresponding speed and running time of the host fan and / or the base station fan according to the selected dust collection coefficient;

[0019] S34: Start the main unit fan and start the base station fan. The main unit fan and / or the base station fan operate according to the dust collection coefficient. The base station fan generates the base station wind force on the garbage in the main unit dust collection chamber, and the main unit fan generates the main unit wind force on the garbage in the main unit dust collection chamber.

[0020] S35: After the main fan reaches its operating time, the cleaning host switches to another dust collection coefficient according to the preset priority order, and then repeats steps S33, S34 and S35 in sequence until the base station finishes collecting the garbage in the cleaning host.

[0021] Preferably, the characteristics of the waste include volume, weight, density, and / or type.

[0022] The technical solution adopted by the present invention to solve its technical problem also includes: providing a cleaning robot, including a memory and a processor;

[0023] The memory is used to store computer programs;

[0024] The processor is used to execute the computer program to implement the above-described efficient dust collection method for the cleaning robot.

[0025] Implementing the technical solution of this invention has at least the following beneficial effects: The efficient dust collection method and cleaning robot of this invention utilize the cooperation of the main unit fan and the base station dust collection fan. The base station fan and the main unit fan together form a total suction force on the debris in the main unit dust collection chamber. Under the action of the total suction force, the debris in the main unit dust collection chamber enters the base station dust collection chamber, i.e., base station dust collection. During the base station dust collection process, the main unit fan and / or the base station fan are controlled according to the characteristics of the debris (such as different characteristics of debris weight, size, density, and type). The magnitude of the base station fan and / or the main unit fan is changed sequentially to change the magnitude of the total suction force. Debris with different characteristics in the main unit dust collection chamber is sent to the base station dust collection chamber in sequence, allowing the debris with different characteristics in the main unit dust collection chamber to enter the base station dust collection chamber in an orderly manner. In this way, the sequentially changed total suction force peels off the clumps of debris layer by layer, dividing a clump of debris into several parts, avoiding the situation where too much debris is sucked in at the same time, which could cause blockage of the base station dust collection port or other narrow locations such as connecting ports, thus improving the dust collection rate.

[0036] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention.

[0037] An efficient dust collection method for a cleaning robot according to one embodiment of the present invention, see [link to relevant documentation]. Figure 1-4 The cleaning robot includes a base station 1 and a cleaning host 2 for cleaning. The cleaning host 2 is equipped with a host fan and a host dust collection chamber, and the cleaning host 2 has a host dust collection port 20 that connects to the host dust collection chamber. The base station 1 is equipped with a base station fan and a base station dust collection chamber, and the base station 1 has a base station dust collection port 10 that connects to the base station dust collection chamber. See [link to details]. Figure 5 The method includes the following steps:

[0038] S1: The cleaning host 2 leaves the base station 1 to perform cleaning, such as sweeping and mopping. The host fan absorbs the cleaned garbage into the host dust collection chamber.

[0039] S2: Cleaning host 2 returns to base station 1;

[0040] S3: The base station dust collection chamber is connected to the host dust collection chamber through the base station dust collection port 10. The base station fan draws air from the host dust collection chamber through the base station dust collection port 10 and the host dust collection port 20, generating base station airflow to remove the debris in the host dust collection chamber. The host fan is connected to the host dust collection chamber and generates host airflow to remove the debris in the host dust collection chamber. The host fan draws air from the host dust collection chamber, and the host airflow is the suction force. The direction of the base station airflow is opposite to the direction of the host airflow. When the host fan draws air from the host dust collection chamber, the base station airflow is greater than the host airflow. The base station airflow and the host airflow together form a total suction force on the debris in the host dust collection chamber. The debris in the host dust collection chamber enters the base station dust collection chamber under the action of the total suction force. By changing the magnitude of the base station airflow and / or the host airflow, the magnitude of the total suction force can be changed, and debris with different characteristics in the host dust collection chamber can be sent to the base station dust collection chamber.

[0041] The efficient dust collection method of the cleaning robot of this invention utilizes the cooperation of the main unit fan and the dust collection fan of base station 1. The combined airflow from the base station and the main unit creates a total suction force on the debris in the main unit's dust collection chamber. Under the action of this total suction force, the debris in the main unit's dust collection chamber enters the base station's dust collection chamber, i.e., dust collection occurs at base station 1. During the dust collection process at base station 1, the main unit fan and / or the base station fan are controlled according to the characteristics of the debris (e.g., different characteristics such as weight, size, density, and type). The airflow from the base station and / or the main unit is changed sequentially to alter the total suction force, thus sequentially sending debris with different characteristics from the main unit's dust collection chamber into the base station's dust collection chamber. This allows the debris with different characteristics in the main unit's dust collection chamber to enter the base station's dust collection chamber in an orderly manner. In this way, the sequentially changing total suction force peels away clumps of debris layer by layer, dividing a clump of debris into several parts. This avoids the situation where too much debris is sucked in at the same time, causing blockage of narrow locations such as the base station's dust collection port 10 or other connecting ports, thereby improving the dust collection rate.

[0042] Specifically, during the process of collecting waste from the main unit's dust collection chamber to base station 1, the base station fan generates a suction force to remove the waste from the main unit's dust collection chamber, while the main unit fan generates a reaction force to pull some of the waste in place. The forces generated by the base station fan and the main unit fan are opposite. The suction force of the base station fan is higher than that of the main unit 2. Different characteristics (such as volume, weight, density, and type of waste) require different total suction forces. For example, larger waste requires more total suction, while heavier and denser waste requires even greater total suction to be drawn into the base station's dust collection chamber. Utilizing this characteristic, changing the base station fan force and / or the main unit fan force will create different suction combinations, thereby altering the total suction force.

[0043] The main unit fan and the main unit dust collection chamber are usually located inside the main unit, and the base station fan and the base station dust collection chamber are usually located inside the base station. The main unit dust collection chamber and the base station dust collection chamber can be cavities in a dust collection box or dust collection bag.

[0044] Further, step S3 includes: the main unit fan blowing air into the main unit dust collection chamber, the main unit fan's airflow being a blowing force, and the base station fan's airflow direction being the same as the main unit fan's airflow direction. Preferably, in step S3, when the main unit fan blows air into the main unit dust collection chamber, the main unit fan's airflow is less than, equal to, or greater than the base station fan's airflow. The main unit fan's blowing air, combined with the base station fan's suction airflow, can further improve the total suction power and increase the dust collection rate of base station 1.

[0045] More preferably, see Figure 6 In step S3, the main unit fan first draws air from the main unit dust collection chamber, and the main unit air force gradually decreases. Then, the main unit fan blows air into the main unit dust collection chamber, and the main unit air force gradually increases.

[0046] Preferably, in the foregoing embodiments, the total suction force gradually increases as the total suction force acts on the dust collection chamber of the main unit.

[0047] Furthermore, the main unit fan and / or base station fan have at least two wind speed settings. For example, the main unit fan has at least two wind speed settings, while the base station fan has a fixed wind speed; or, the main unit fan has a fixed wind speed, while the base station fan has at least two wind speed settings; or, both the main unit fan and the base station fan have at least two wind speed settings. Specifically, for example, the main unit fan has four wind speed settings, with the first setting being the highest and the fourth setting being the lowest, switching sequentially from the first to the fourth setting. When the cleaning main unit 2 operates at the first setting, a relatively strong airflow is generated for the debris clumps in the main unit's dust collection chamber, separating the debris surrounding the debris clumps from the clumps. Smaller, lighter, and less dense debris is preferentially sucked into the base station 1. After a period of time, the cleaning host 2 operates at the second speed, reducing the pulling force. Larger, heavier, and denser debris located on the periphery will then be sucked back into base station 1. This process continues as the speed of the cleaning host 2 decreases, causing some debris to break free from the pulling force and be sucked into the base station's dust collection chamber. This continues until base station 1 finishes dust collection, at which point all debris has been sucked into the dust collection chamber. This layered separation of debris breaks down a clump into several parts, preventing too much debris from being sucked in at the same time and clogging the base station's dust collection port 10 or other narrow openings, thus improving the dust collection rate.

[0048] Specifically, preferably, see Figure 7 Step S3 includes the following steps:

[0049] S31: Based on the characteristics of the waste, the waste is divided into at least two categories. Each category of waste is assigned a waste coefficient, and each waste coefficient corresponds to a dust collection coefficient. Each dust collection coefficient includes the operating speed and operating time of the main unit fan and / or base station fan.

[0050] S32: The cleaning host 2 selects one of the dust collection coefficients (e.g., the first dust collection coefficient) according to the preset priority order;

[0051] S33: The cleaning host 2 determines the corresponding host fan and / or base station fan speed and running time according to the selected dust collection coefficient;

[0052] S34: When the main fan is started, the cleaning host 2 roller brush motor can also be started to drive the roller brush 21 to rotate, and the base station fan can be started to run. The main fan and / or the base station fan run according to the dust collection coefficient. The base station fan generates base station wind force to suck away the garbage in the dust collection chamber of the main host, and the main fan generates main host wind force to suck away the garbage in the dust collection chamber of the main host.

[0053] S35: After the main fan reaches the running time, the cleaning host 2 switches to another dust collection coefficient (e.g., the second dust collection coefficient) according to the preset priority order, and then repeats steps S33, S34 and S35 in sequence until the base station 1 finishes collecting the garbage in the cleaning host 2.

[0054] See Figure 8 The following example illustrates the efficient dust collection method of the cleaning robot, which uses a main unit fan with four wind speed settings and a base station fan with a fixed wind speed.

[0055] S311: The cleaning host 2 leaves the base station 1 to perform cleaning, such as sweeping and mopping. The host fan absorbs the cleaned garbage into the host dust collection chamber.

[0056] S312: Cleaning host 2 returns to the base station after cleaning;

[0057] S303: All waste is divided into four categories according to weight, size and type, and a waste coefficient is set for each category;

[0058] S304: All waste is divided into four categories according to weight, size and type. Each category corresponds to a dust collection coefficient. Each dust collection coefficient includes the operating speed and running time of the main fan.

[0059] S305: The cleaning host 2 selects one of the dust collection coefficients according to the preset priority order, namely the first dust collection coefficient;

[0060] S306: The cleaning host 2 determines the corresponding host fan speed and running time based on the selected first dust collection coefficient;

[0061] S307: When the main fan is started, the cleaning host 2 roller brush motor can also be started to drive the roller brush 21 to rotate, and the base station fan can be started to run. The main fan runs according to the first dust collection coefficient. The base station fan generates base station wind force on the garbage in the main dust collection chamber to suck away the garbage. The main fan generates main fan wind force on the garbage in the main dust collection chamber.

[0062] S308: After the main fan reaches the running time, the cleaning host 2 switches to another dust collection coefficient, namely the second dust collection coefficient, according to the preset priority order;

[0063] S309: The cleaning host 2 sets the corresponding host fan speed and running time according to the selected second dust collection coefficient;

[0064] S310: The main unit fan operates according to the second dust collection coefficient, the main unit 2 roller brush motor continues to run, and the base station fan continues to run;

[0065] S311: After the main fan reaches the running time, the cleaning host 2 switches to the next dust collection coefficient, i.e. the third dust collection coefficient, according to the preset priority order;

[0066] S312: The cleaning host 2 sets the corresponding host fan speed and running time according to the selected third dust collection coefficient;

[0067] S313: The main unit fan operates according to the third dust collection coefficient, the main unit 2 roller brush motor continues to run, and the base station fan continues to run;

[0068] S314: After the main fan reaches the running time, the cleaning host 2 switches to the next dust collection coefficient, i.e. the fourth dust collection coefficient, according to the preset priority order;

[0069] S315: The cleaning host 2 sets the corresponding host fan speed and running time according to the selected fourth dust collection coefficient;

[0070] S316: The main unit fan operates according to the fourth dust collection coefficient, the cleaning main unit 2 roller brush motor continues to run, and the base station fan continues to run;

[0071] S317: After the main fan reaches its operating time, the main fan stops running, the cleaning main fan 2 roller brush stops running, and the base station fan stops running;

[0072] S318: Base station 1 ends the collection of garbage in the dust collection chamber of the main unit of cleaning host 2.

[0073] Preferably, in the foregoing embodiments, the characteristics of the waste include volume, weight, density, and / or type.

[0074] See Figure 1-4 A cleaning robot according to one embodiment of the present invention includes a memory and a processor;

[0075] Memory is used to store computer programs;

[0076] The processor is used to execute computer programs to implement the efficient dust collection method of the cleaning robot described above.

[0077] Specifically, according to embodiments of the present invention, the process of the efficient dust collection method for the cleaning robot described above can be implemented as a computer software program. For example, embodiments of the present invention include a computer program product comprising a computer program carried on a computer-readable medium, the computer program containing program code for performing the method shown in the flowchart. In such embodiments, when the computer program is downloaded and installed by an electronic device and executed, it performs the functions defined in the method of the embodiments of the present invention.

[0078] The cleaning robot of this invention utilizes the aforementioned efficient dust collection method, employing a combination of the main unit's fan and the dust collection fan of base station 1. The combined airflow from the base station and the main unit creates a total suction force on the debris in the main unit's dust collection chamber. Under this total suction, the debris enters the base station's dust collection chamber, thus achieving dust collection at base station 1. During dust collection at base station 1, the main unit's fan and / or the base station's fan are controlled according to the characteristics of the debris (e.g., weight, size, density, and type). The airflow from the base station and / or the main unit is sequentially changed to alter the total suction force, sequentially sending debris with different characteristics from the main unit's dust collection chamber into the base station's dust collection chamber. This orderly arrangement of debris from the main unit's dust collection chamber into the base station's dust collection chamber, through the sequentially changing total suction force, peels away clumps of debris layer by layer, dividing a clump into several parts. This prevents too much debris from being sucked in simultaneously, which could clog the base station's dust collection port 10 or other narrow openings, thereby improving the dust collection rate.

[0079] Specifically, during the process of collecting waste from the main unit's dust collection chamber to base station 1, the base station fan generates a suction force to remove the waste from the main unit's dust collection chamber, while the main unit fan generates a reaction force to pull some of the waste in place. The forces generated by the base station fan and the main unit fan are opposite. The suction force of the base station fan is higher than that of the main unit 2. Different characteristics (such as volume, weight, density, and type of waste) require different total suction forces. For example, larger waste requires more total suction, while heavier and denser waste requires even greater total suction to be drawn into the base station's dust collection chamber. Utilizing this characteristic, changing the base station fan force and / or the main unit fan force will create different suction combinations, thereby altering the total suction force.

[0080] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
