Description

Technical Field

[0001] The present invention relates to the technical field of pool cleaning equipment, and particularly relates to a pool cleaning robot with a steering structure. Background Art

[0002] With the rapid development of the times, many families can install swimming pools (including underground and above-ground swimming pools) at home. The swimming pool is a place for people to have entertainment and play. However, whether it is an outdoor pool or an indoor pool, after being used for a period of time, there will be some garbage or bacteria at the bottom of the pool. Especially, dirt adheres to the bottom of the pool, and normal circulating water filtration cannot effectively clean it. Therefore, the pool needs to be cleaned regularly.

[0003] Pool cleaning robots (including underwater and surface robots) can perform pool cleaning work. Currently, the general pool cleaning robots generally rely on random walking to achieve covering cleaning of the pool, and the cleaning effect is not good. Summary of the Invention

[0004] Aiming at the technical problems in the prior art, the present invention provides a pool cleaning robot with a steering structure, which can control the movement trajectory of the robot and has a certain turning ability, so that the robot can effectively reach all areas that need to be cleaned, improve the movement coverage rate of the robot, and thus achieve the purpose of improving the cleaning effect.

[0005] The technical solution includes a main body. A garbage bin is arranged inside the main body. The garbage bin is communicated with the outside through a sewage suction port at the bottom. A water spray port is arranged on the side of the main body. The water spray port is communicated with the garbage bin. Four walking wheels are further arranged at the bottom of the main body. The walking wheels are detachably connected to the main body. The spoke of at least one of the walking wheels is in the shape of a fan blade.

[0006] Preferably, the spokes of all four walking wheels are in the shape of fan blades.

[0007] Preferably, the spokes of the four walking wheels are symmetrically arranged with respect to the main body, and the spokes of the two walking wheels on the same side are the same.

[0008] Preferably, the spokes of the two front walking wheels and the two rear walking wheels are all the same, and the spokes of the front walking wheels and the rear walking wheels are different.

[0009] Preferably, the fan-shaped spokes are centrosymmetrically arranged about their geometric centers.

[0010] Preferably, a plurality of weight reduction holes are arranged at intervals on the spokes.

[0011] Preferably, the included angle between the spoke and the edge surface of the wheel is m, and the range of m is between 30° and 40°.

[0012] Preferably, the wheelbase q of the front and rear traveling wheels is greater than or equal to 2 times the body width p.

[0013] Preferably, the traveling wheel is provided with a detachable wheel cover, and the number of the wheel covers matches the number of the fan-shaped spokes.

[0014] Advantageous effects:

[0015] 1. Through the arrangement of the fan-shaped spokes and the spoke directions, the present invention can adjust the forward running direction, has a simple structure, is convenient to adjust, and does not increase additional structures and costs. Specifically, the fan-shaped spokes make the traveling wheel itself an impeller. When the wheel moves forward, such a traveling wheel can provide a lateral thrust, so that the pool robot can be controlled to move in a certain direction by adjusting the traveling wheel, without additionally installing a baffle or other steering structures.

[0016] 2. Through the arrangement that the fan shape of the spokes is centrosymmetric about its geometric center, the present invention can make the reverse thrust generated by the traveling wheel the same whether it rotates forward or backward, which is convenient for adjustment and control; combined with the arrangement of the weight reduction holes, the weight of the traveling wheel can be reduced, thereby reducing the resistance of the traveling wheel and reducing energy consumption; through the arrangement that the range of the angle m is between 30° and 40°, the lateral thrust of the traveling wheel can be reasonably controlled, preventing too much resistance to the forward movement of the pool cleaning robot, and at the same time ensuring that the moving speed of the pool cleaning robot will not be greatly affected.

[0017] 3. Through the arrangement that the wheelbase q of the front and rear traveling wheels is greater than or equal to 2 times the body width p, the present invention can make it easier for the pool cleaning robot to turn rather than translate.

[0018] 4. Through the arrangement of the detachable wheel cover, the present invention can eliminate the function of the fan-shaped spokes, so that the pool cleaning robot can move straight forward or move in other directions. Description of the drawings

[0027] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The present invention provides a pool cleaning robot with a steering structure, as Figure 1 , Figure 2 shown, including a body 1. A dustbin 2 is provided inside the body 1. The dustbin 2 communicates with the outside through a suction port 3 at the bottom. A water spray port 4 is provided on the side of the body 1. The water spray port 4 communicates with the dustbin 2. Four traveling wheels 5 are further provided at the bottom of the body 1. The traveling wheels 5 are detachably connected to the body 1. When the water spray port 4 sprays water to the right, the body 1 moves leftward along with the traveling wheels 5, as Figure 1 shown by the large arrow in the figure. At least one of the wheel spokes 51 of the traveling wheels 5 is in the shape of a fan blade. Preferably, the wheel spokes 51 of all four traveling wheels 5 are in the shape of fan blades. Through the arrangement of the four fan-shaped wheel spokes 51, on the one hand, it can accelerate the adjustment of the movement direction, and on the other hand, it can also realize the adjustment of various working modes. Specifically, it includes a straight-line mode, a left-turn mode, and a right-turn mode. When in the straight-line mode, as Figure 3 shown, the wheel spokes 51 of the four traveling wheels 5 are symmetrically arranged with respect to the body 1, and the wheel spokes 51 of the two traveling wheels 5 on the same side are the same. At this time, for the water flow direction passing through the wheel spokes 51, if it flows outward away from the body 1, a deceleration effect can be achieved, thereby preventing incomplete cleaning caused by the pool cleaning robot moving too fast and further improving the cleaning effect; when in the left- and right-turn modes, the wheel spokes 51 of the two front traveling wheels and the two rear traveling wheels are the same, and the wheel spokes 51 of the front traveling wheels and the rear traveling wheels are different. When the water flow direction of the two front traveling wheels is from right to left and the water flow direction of the two rear traveling wheels is from left to right, it is the left-turn mode, as Figure 4 shown, and when the water flow direction of the two front traveling wheels is from left to right and the water flow direction of the two rear traveling wheels is from right to left, it is the right-turn mode, as Figure 5As shown, the moving direction of the cleaning robot is as indicated by the large arrow in the figure, and the water flow direction is as indicated by the small arrow in the figure.

[0029] In this embodiment, by setting the fan-shaped spokes 51 and the direction of the spokes 51, the adjustment of the forward running direction can be realized, and the structure is simple, the adjustment is convenient, and at the same time, no additional structure and cost are added. Specifically, the fan-shaped spokes 51 make the walking wheel 5 itself an impeller. When the wheel moves forward, such a walking wheel 5 can provide a lateral thrust, so that by adjusting the walking wheel 5, the pool robot can be controlled to move in a certain direction, and there is no need to additionally install a baffle or other steering structures.

[0030] Preferably, as Figure 2 , Figure 6 shown, the fan shape of the spokes 51 is centrosymmetrically arranged about its geometric center; a plurality of weight-reducing holes 52 are provided at intervals on the spokes 51; the included angle between the spokes 51 and the edge surface of the wheel is m, and the range of m is between 30° and 40°.

[0031] In this embodiment, by setting the fan shape of the spokes 51 to be centrosymmetrically arranged about its geometric center, the reverse thrust generated by the walking wheel 5 can be the same whether it rotates forward or backward, which is convenient for adjustment and control; combined with the setting of the weight-reducing holes 52, the weight of the walking wheel 5 can be reduced, thereby reducing the resistance of the walking wheel 5 and reducing energy loss; by setting the range of the included angle m between 30° and 40°, the lateral thrust of the walking wheel 5 can be reasonably controlled, preventing too much resistance to the forward movement of the pool cleaning robot, and at the same time ensuring that the moving speed of the pool cleaning robot will not be greatly affected.

[0032] Preferably, as Figure 4 , Figure 7 shown, the wheelbase q of the front and rear walking wheels is greater than or equal to 2 times the width p of the body 1 or the fuselage.

[0033] In this embodiment, by setting the wheelbase q of the front and rear walking wheels to be greater than or equal to 2 times the width p of the body 1 or the fuselage, the pool cleaning robot can more easily turn instead of translating, and the time taken to turn 90° is close to 15 s.

[0034] Preferably, as Figure 1 , Figure 2 shown, a detachable wheel cover (not shown in the figure) is provided on the walking wheel 5, and the number of the wheel covers (not shown in the figure) matches the number of the fan-shaped spokes 51.

[0035] In this embodiment, by setting the detachable wheel cover (not shown in the figure), the function of the fan-shaped spokes 51 can be eliminated, so that the pool cleaning robot can move straight forward or move in other directions.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
