Description

Technical Field

[0001] The present invention relates to the field of cleaning equipment, and in particular to a high-efficiency dust collection method of a cleaning robot and the cleaning robot. Background Art

[0002] A 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 garbage into its own host dust collection chamber, and then returns to the base station. The base station collects the garbage in the host dust collection chamber into the base station dust collection chamber.

[0003] Among them, after the cleaning host returns to the base station, the base station is connected to the host dust collection chamber through the base station dust collection port, and by turning on the built-in dust collection fan, the garbage in the cleaning host is sucked out through the base station dust collection port and stored in the base station dust collection chamber, thereby realizing the dust collection function. It is generally believed that the greater the air volume during dust collection, the better. The greater the air volume means the stronger the suction force, which can collect the garbage in the cleaning host into the base station dust collection chamber faster and more thoroughly. However, the garbage in daily life is relatively messy, including hair, melon seed shells, peanut shells, thread ends, etc. When the cleaning host sucks it into the host dust collection chamber, it is squeezed by the suction force and often shrinks into a ball. In this way, if there is more garbage in the host dust collection chamber, the volume of the garbage ball will be relatively large. During the dust collection process of the base station, the base station fan uses a large suction force, which will likely cause the garbage to block all the narrow channels such as the roller brush port and the dust box port at once, resulting in a low dust collection rate.

[0036] In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0037] An efficient dust collection method for a cleaning robot in one embodiment of the present invention is described in detail in Figure 1-4 The cleaning robot includes a base station 1 and a cleaning host 2 for cleaning. The cleaning host 2 is provided with a host fan and a host dust collecting chamber. The cleaning host 2 is provided with a host dust collecting port 20 connected to the host dust collecting chamber. The base station 1 is provided with a base station fan and a base station dust collecting chamber. The base station 1 is provided with a base station dust collecting port 10 connected to the base station dust collecting chamber. Figure 5 , the method comprises the following steps:

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

[0039] S2: Clean host 2 and return to base station 1;

[0040] S3: The base station dust collecting chamber is connected with the host dust collecting chamber through the base station dust collecting port 10, and the base station fan draws air from the host dust collecting chamber through the base station dust collecting port 10 and the host dust collecting port 20, generating base station wind force for the garbage in the host dust collecting chamber to suck away the garbage, the host fan is connected to the host dust collecting chamber and generates host wind force for the garbage in the host dust collecting chamber, the host fan draws air from the host dust collecting chamber, the host wind force is suction force and the direction of the base station wind force is opposite to the direction of the host wind force, when the host fan draws air from the host dust collecting chamber, the base station wind force is greater than the host wind force; the base station wind force and the host wind force together form a total suction force on the garbage in the host dust collecting chamber, and the garbage in the host dust collecting chamber enters the base station dust collecting chamber under the action of the total suction force; change the size of the base station wind force and / or the host wind force to change the size of the total suction force, and send garbage with different characteristics in the host dust collecting chamber to the base station dust collecting chamber.

[0041] The efficient dust collection method of the cleaning robot of the present invention utilizes the cooperation of the main machine fan and the dust collection fan of the base station 1. The wind force of the base station and the main machine wind force jointly form a total suction force for the garbage in the main machine dust collection chamber. The garbage in the main machine dust collection chamber enters the base station dust collection chamber under the action of the total suction force, that is, the dust is collected by the base station 1. During the dust collection process of the base station 1, the main machine fan and / or the base station fan are controlled according to the characteristics of the garbage (such as different characteristics such as garbage weight, size, density and type), and the size of the base station wind force and / or the main machine wind force is changed in turn to change the size of the total suction force, and the garbage with different characteristics in the main machine dust collection chamber is sent to the base station dust collection chamber in turn, so that the garbage with different characteristics in the main machine dust collection chamber is orderly queued and enters the base station dust collection chamber. In this way, the total suction force that changes in turn peels off the clumped garbage layer by layer and divides a clumped garbage into several parts, thereby avoiding too much garbage being sucked in at the same time, resulting in blocking the narrow position such as the base station dust collection port 10 or other connecting ports, thereby improving the dust collection rate of the garbage.

[0042] Specifically, in the process of collecting garbage in the dust collecting chamber of the host to the base station 1, the base station fan generates a suction force on the garbage in the dust collecting chamber of the host to suck away the garbage, and the host fan generates a reaction force on the garbage in the dust collecting chamber of the host to pull part of the garbage in the process. The forces generated by the base station fan and the host fan are opposite. The suction force of the base station fan is higher than the suction force of the cleaning host 2. Different characteristics (such as volume, weight, density and type of garbage) require different total suction forces. For example, large garbage will receive a greater total suction force, while heavier and denser garbage will require a greater total suction force to be sucked into the dust collecting chamber of the base station. By taking advantage of this feature, the base station wind force and / or host wind force can be changed, and the base station wind force and the host wind force will produce different suction combinations to change the total suction force.

[0043] Among them, the host fan and the host dust collecting chamber are usually arranged inside the host, and the base station fan and the base station dust collecting chamber are usually arranged inside the base station. The host dust collecting chamber and the base station dust collecting chamber can be cavities in a dust box or a dust bag.

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

[0045] More preferably, see Figure 6 In step S3, the host blower first draws air from the host dust collecting chamber, and the host wind force gradually decreases. Then, the host blower blows air into the host dust collecting chamber, and the host wind force gradually increases.

[0046] Preferably, in each of the aforementioned embodiments, during the process in which the total suction force acts on the garbage in the dust collecting chamber of the main unit, the total suction force increases from small to large.

[0047] Furthermore, the host fan and / or the base station fan are provided with at least two wind speed gears. For example, the host fan is provided with at least two wind speed gears, and the wind speed of the base station fan is fixed; or, the wind speed of the host fan is fixed, and the base station fan is provided with at least two wind speed gears; or, both the host fan and the base station fan are provided with at least two wind speed gears. Specifically, for example, the host fan is provided with four wind speed gears, the first gear is the maximum gear, the fourth gear is the minimum gear, and the gears are switched from the first gear to the fourth gear one by one. When the cleaning host 2 is operated in the first gear in stages, a relatively large host wind force is generated for the garbage ball in the dust collecting chamber of the host, which will separate the garbage outside the garbage ball from the garbage ball, and those garbage with small size, light weight and low density will be sucked into the base station 1 first. After a period of time, the cleaning host 2 runs into the second gear, the pulling force is reduced, and the garbage with a larger volume, a heavier weight, a higher density, and located on the periphery will be sucked back into the base station 1 by the base station 1. Similarly, when the gears in the cleaning host 2 are gradually reduced, some garbage will break free from the pulling force and be sucked into the dust collection chamber of the base station until the dust collection of the base station 1 is completed and all the garbage is sucked into the dust collection chamber of the base station. The garbage is peeled off layer by layer, and a group of garbage is divided into several parts. This prevents too much garbage from being sucked in at the same time, resulting in blocking the narrow locations such as the base station dust collection port 10 or other connecting ports, thereby improving the dust collection rate of the garbage.

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

[0049] S31: Classify the garbage into at least two categories based on the characteristics of the garbage, set a garbage coefficient for each category of garbage, each garbage coefficient corresponds to a dust collection coefficient, and each dust collection coefficient includes the gear and operating time of the host fan and / or the base station fan;

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

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

[0052] S34: Start the host fan and at the same time start the roller brush motor of the cleaning host 2 to drive the roller brush 21 to rotate, start the base station fan, the host fan and / or the base station fan operate according to the dust collection coefficient, the base station fan generates base station wind force for the garbage in the host dust collection chamber to suck away the garbage, and the host fan generates host wind force for the garbage in the host dust collection chamber;

[0053] S35: After the host fan reaches the running time, the cleaning host 2 switches to another dust collection coefficient (for example, the second dust collection coefficient) according to the preset priority, 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 also Figure 8 The following is a specific description of an embodiment in which the main blower has four wind speed levels and the base blower has a fixed wind speed. In this embodiment, the efficient dust collection method of the cleaning robot includes the following steps:

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

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

[0058] S304: All garbage 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 gear and operating time of the main machine fan;

[0078] The cleaning robot of the present invention operates the aforementioned efficient dust collection method of the cleaning robot, utilizing the main unit fan and the base station 1 dust collection fan to cooperate, with the base station wind force and the main unit wind force jointly forming a total suction force on the garbage in the main unit dust collection chamber, and the garbage in the main unit dust collection chamber enters the base station dust collection chamber under the action of the total suction force, i.e., dust collection by base station 1.

The forces generated by the base station fan and the host fan are opposite. The suction force of the base station fan is higher than the suction force of the cleaning host 2. Different characteristics (such as volume, weight, density and type of garbage) require different total suction forces. For example, large garbage will receive a greater total suction force, while heavier and denser garbage will require a greater total suction force to be sucked into the dust collecting chamber of the base station. By taking advantage of this feature, the base station wind force and / or host wind force can be changed, and the base station wind force and the host wind force will produce different suction combinations to change the total suction force.
