Description

Technical Field

[0001] The present invention relates to the technical field of pool cleaning equipment, and particularly relates to a centrifugal pool cleaning robot for improving cleaning efficiency and coverage rate. 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. Swimming pools are places for people to have entertainment and play. However, whether it is an open-air 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 water surface and underwater robots) can perform pool cleaning work, and mainly carry cleaning mechanisms to move in the water. In order to ensure the cleaning effect, it is necessary to effectively improve the cleaning efficiency and coverage rate of the robot. Therefore, the cleaning ability and the stability of the machine speed of the robot are indispensable performances of the machine.

[0004] The characteristics of a centrifugal water pump are fast flow rate and small drainage volume. The suction force of the robot with the same drainage volume is the same. If a large drainage volume is required, the flow rate needs to be increased, and in this way, the machine speed will become very fast. Although a fast speed will increase the coverage rate, the cleaning efficiency will drop significantly. If the flow rate is adjusted slower, the drainage volume will be small, which will affect both the cleaning efficiency and the coverage rate. It is very difficult to achieve a regular relationship between the two. How to achieve a relatively balanced cleaning efficiency and speed, and synchronously improve both the cleaning rate and the coverage rate is an urgent problem to be solved. Summary of the Invention

[0005] Aiming at the technical problems in the prior art, the present invention provides a centrifugal pool cleaning robot for improving cleaning rate and coverage rate. By means of a cover plate at the water outlet, the sprayed water flow is dispersed upward, so as to reduce the concentration of the water flow in one place, which can reduce the speed of the cleaning robot and increase the downward pressure of the machine at the same time. In this way, the cleaning efficiency and speed can be relatively balanced, and both the cleaning rate and the coverage rate can be synchronously improved.

[0006] The technical solution includes a body. A filter chamber is provided inside the body, and a filter basket is provided in the filter chamber. At least one water inlet is provided at the bottom of the body, and the water inlet is communicated with the filter basket. At least one water outlet is provided at the side of the body, and the water outlets correspond to the water inlets one by one. The water outlets are communicated with the filter chamber. The solution further includes a cover plate, which is hinged to the body, and the hinged position is above the outside of the water outlet. The size of the cover plate is larger than the size of the water outlet. When there is no water flow spraying out, the cover plate covers the water outlet. When there is water flow spraying out, the cover plate is opened by the impact of the water flow to open the water outlet, and part of the water flow sprays out along the inner wall of the cover plate.

[0007] Preferably, the lifting angle when the cover plate is opened is 90° to 115°, and the lifting angle is used to adjust the spraying speed and spraying angle of the water flow.

[0008] Preferably, the length dimension of the cover plate in the opening direction is 45 mm, the width dimension is 70 mm, the distance from the hinge position to the top end of the water outlet is 20 mm, and the lifting angle when the cover plate is opened is 90°.

[0009] Preferably, the length dimension of the cover plate in the opening direction is 35 mm, the width dimension is 70 mm, the distance from the hinge position to the top end of the water outlet is 3 mm, and the lifting angle when the cover plate is opened is 115°.

[0010] Preferably, the length dimension of the cover plate in the opening direction is 45 mm, the width dimension is 70 mm, the distance from the hinge position to the top end of the water outlet is 3 mm, and the lifting angle when the cover plate is opened is 110°.

[0011] Preferably, the length dimension of the cover plate in the opening direction is 40 mm, the width dimension is 70 mm, the distance from the hinge position to the top end of the water outlet is 8 mm, and the lifting angle when the cover plate is opened is 100°.

[0012] Preferably, a handle is further installed on the body. The handle is located above the cover plate. The distance from the connection position of the handle and the body to the hinge position ranges from 10 mm to 15 mm. The handle is inclined, and the included angle between the handle and the end face of the water outlet ranges from 100° to 105°.

[0013] Preferably, a streamline-shaped backflow plate is provided on the side of the handle close to the cover plate, and the streamline-shaped backflow plate overlaps with the end of the cover plate.

[0014] Preferably, the side of the cover plate close to the water outlet is set to be arc-shaped, and the dimension of the height of the arc ranges from 2 mm to 8 mm.

[0015] Preferably, a filter channel is provided between the water outlet and the filter chamber.

[0016] Beneficial effects:

[0017] 1. Through the size settings of the cover plate at the water outlet and the cover plate, the present invention can disperse the sprayed water flow upward by using the cover plate, thereby reducing the concentration of the water flow in one place, so that the speed of the cleaning robot is reduced. At the same time, the downward pressure of the cleaning robot can be increased, and thus the cleaning ability can be improved, so that the cleaning efficiency and coverage rate can be well improved.

[0018] 2. Through the cooperative setting of the handle, the present invention can continuously trigger the "Coanda effect" to continue the upward water flow, enabling the cleaning robot to maintain a relatively average speed, reaching the ideal state defined by the product, with strong suction, neither too fast nor too slow speed, and greatly improving the cleaning efficiency and coverage rate. Combined with the setting of the streamlined backflow plate, the water flow ejected from the water outlet can be made smoother.

[0019] 3. By setting the side of the cover plate close to the water outlet into an arc with the height of the arc ranging from 2 mm to 8 mm, the present invention can make the water flow more concentrated, ensuring the formation of a converging water flow while also facilitating the lifting of the cover plate without affecting the speed.

[0020] 4. Through the setting of the filtration channel, the present invention can improve the disinfection and filtration effect of the water flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention mainly solves the problem that the cleaning efficiency and speed of a centrifugal pump type pool cleaning robot can increase synchronously. As is well known, to improve the cleaning efficiency of the machine, its flow rate must increase. How to weaken the speed of the machine at the same flow rate to achieve a relatively balanced result between cleaning efficiency and speed is the focus of the present invention. Through a series of verifications, it can be proved that the continuous "Coanda effect" can solve the problems of the present invention.

[0030] Embodiment 1

[0031] The present invention provides a centrifugal pool cleaning robot for improving the cleaning rate and coverage rate. As Figures 1 to 6 shown, it includes a body 1. Four wheels are provided at the bottom of the body 1. Through the setting of the four wheels, it is convenient for the cleaning robot to move back and forth under the action of water flow. A filtering cavity is provided inside the body 1, and a filtering basket is provided in the filtering cavity. At least one water inlet is provided at the bottom of the body 1. Preferably, the water inlet includes two. The water inlet is communicated with the filtering basket. At least one water outlet 2 is provided at the side of the body 1, and the water outlet 2 corresponds to the water inlet one by one. The water outlet 2 is communicated with the filtering cavity or the filtering basket. Preferably, a filtering channel is provided between the water outlet 2 and the filtering cavity, which can improve the disinfection and filtering effect on the water flow. It further includes a cover plate 3. The cover plate 3 is hinged to the body 1, and the hinged position is above the outside of the water outlet 2. The size of the cover plate 3 is larger than the size of the water outlet 2. When there is no water flow spraying out, the cover plate 3 covers the water outlet 2. When there is water flow spraying out, the cover plate 3 is opened by the impact of the water flow to open the water outlet 2, and part of the water flow sprays out along the inner wall of the cover plate 3. The lifting angle when the cover plate 3 is opened is 90° to 115°, and the lifting angle is used to adjust the spraying speed and spraying angle of the water flow.

[0032] In this embodiment, through the setting of the cover plate 3 and the size of the cover plate 3 at the water outlet 2, the sprayed water flow can be dispersed upward by using the cover plate 3, so as to reduce the concentration of the water flow in one place, thereby reducing the speed of the cleaning robot. At the same time, the downward pressure of the cleaning robot can be increased, and then the cleaning ability can be improved, so that the cleaning efficiency and coverage rate can be well improved.

[0033] Embodiment 2

[0034] On the basis of Embodiment 1, preferably, as Figure 2 shown, the length dimension of the cover plate 3 along the opening direction is 45 mm, the width dimension is 70 mm, the distance from the hinged position to the top of the water outlet 2 is 20 mm, the lifting angle when the cover plate 3 is opened is 90°, and the maximum lifting angle of the cover plate 3 is 105°.

[0035] In this embodiment, through the above settings, the upper point of the water flow ejected from the water outlet 2 is slightly above, and the lower point is slightly in the middle, and the overall water flow is towards the middle. At this time, the speed of the cleaning robot is relatively fast, but it can achieve the effect of cleaning the swimming pool.

[0036] Preferably, as Figure 2 shown, one side of the cover plate 3 close to the water outlet 2 is set to be arc-shaped, and the size range of its arc height is 2 mm to 8 mm.

[0037] In this embodiment, by setting one side of the cover plate 3 close to the water outlet 2 to be arc-shaped with the size range of its arc height being 2 mm to 8 mm, it can make the water flow more concentrated. While ensuring that the water flow forms a converging flow, it can also easily lift the cover plate 3 and does not affect the speed.

[0038] Embodiment 3

[0039] On the basis of Embodiment 1, preferably, as Figure 3 shown, the length dimension of the cover plate 3 along the opening direction is 35 mm, the width dimension is 70 mm, the distance from the hinge position to the top of the water outlet 2 is 3 mm, the lifting angle when the cover plate 3 is opened is 115°, and the maximum lifting angle of the cover plate 3 is 135°.

[0040] In this embodiment, through the above settings, a part of the upper end of the water flow ejected from the water outlet 2 is all upward, and most of the lower end is in the middle, and the overall water flow is upward. At this time, due to the overly dispersed water flow, the downward pressure of the cleaning robot is too large and the speed is slow, but it can achieve the effect of cleaning the swimming pool.

[0041] Preferably, as Figure 3 shown, one side of the cover plate 3 close to the water outlet 2 is set to be arc-shaped, and the size range of its arc height is 2 mm to 8 mm.

[0042] In this embodiment, by setting one side of the cover plate 3 close to the water outlet 2 to be arc-shaped with the size range of its arc height being 2 mm to 8 mm, it can make the water flow more concentrated. While ensuring that the water flow forms a converging flow, it can also easily lift the cover plate 3 and does not affect the speed.

[0043] Embodiment 4

[0044] On the basis of Embodiment 1, preferably, as Figure 4 shown, the length dimension of the cover plate 3 along the opening direction is 45 mm, the width dimension is 70 mm, the distance from the hinge position to the top of the water outlet 2 is 3 mm, the lifting angle when the cover plate 3 is opened is 110°, and the maximum lifting angle of the cover plate 3 is 135°. At this time, due to the relatively long length of the cover plate 3 and its closeness to the water outlet 2, the cover plate 3 cannot completely close the water outlet 2.

[0045] In this embodiment, through the above settings, all the upper ends of the water flow ejected from the water outlet 2 face upward, a small part of the lower end is centered, and the overall water flow faces upward. The water flow is more concentrated than that in Embodiment 3. At this time, the cleaning robot starts at a slower speed but can move normally, and the cleaning effect is very good.

[0046] Preferably, as Figure 4 shown, the side of the cover plate 3 close to the water outlet 2 is set to be arc-shaped, and the size range of its arc height is 2 mm to 8 mm.

[0047] In this embodiment, by setting the side of the cover plate 3 close to the water outlet 2 to be arc-shaped with the size range of its arc height being 2 mm to 8 mm, the water flow can be made more concentrated. While ensuring that the water flow forms a converging flow, it can also easily lift the cover plate 3 without affecting the speed.

[0048] Embodiment 5

[0049] On the basis of Embodiment 1, preferably, as Figure 5 shown, the length dimension of the cover plate 3 along the opening direction is 40 mm, the width dimension is 70 mm, the distance from the hinge position to the top end of the water outlet 2 is 8 mm, the lifting angle when the cover plate 3 is opened is 100°, and the maximum lifting angle of the cover plate 3 is 130°.

[0050] In this embodiment, through the above settings, the overall water flow ejected from the water outlet 2 is biased upward, the spraying distance is shorter than that in Embodiment 4, and the water flow is more concentrated. At this time, the cleaning robot starts faster than in Embodiment 4, and the cleaning effect is very good.

[0051] Preferably, as Figure 5 shown, the side of the cover plate 3 close to the water outlet 2 is set to be arc-shaped, and the size range of its arc height is 2 mm to 8 mm.

[0052] In this embodiment, by setting the side of the cover plate 3 close to the water outlet 2 to be arc-shaped with the size range of its arc height being 2 mm to 8 mm, the water flow can be made more concentrated. While ensuring that the water flow forms a converging flow, it can also easily lift the cover plate 3 without affecting the speed.

[0053] Embodiment 6

[0054] On the basis of this Embodiment 5, preferably, as Figure 6 shown, a handle 4 is further installed on the body 1. The handle 4 is located above the cover plate 3. The distance range from the connection position of the handle 4 and the body 1 to the hinge position is 10 mm to 15 mm. The handle 4 is inclined, and the included angle range between it and the end face of the water outlet 2 is 100° to 105°.

[0055] In this embodiment, through the cooperative setting of the handle 4, the "Coanda effect" can be continuously triggered to continue the upward water flow, enabling the cleaning robot to maintain a relatively average speed, so that the cleaning robot reaches the ideal state defined by the product, with strong suction, neither too fast nor too slow speed, and greatly improving the cleaning efficiency and coverage rate.

[0056] Preferably, as Figure 6 shown, a streamline-shaped backflow plate 5 is provided on the side of the handle 4 close to the cover plate 3. The streamline-shaped backflow plate 5 is lapped with the end of the cover plate 3. With the setting of the streamline-shaped backflow plate 5, the water flow ejected from the water outlet 2 can be made smoother.

[0057] Preferably, as Figure 6 shown, the side of the cover plate 3 close to the water outlet 2 is set to be curved, and the dimension range of its camber height is 2 mm to 8 mm.

[0058] In this embodiment, through the setting that the side of the cover plate 3 close to the water outlet 2 is set to be curved and the dimension range of its camber height is 2 mm to 8 mm, the water flow can be made more concentrated, ensuring that the water flow forms a converging flow while also facilitating the lifting of the cover plate 3 without affecting the speed.

[0059] To sum up, as Figures 2 to 6 shown, the technical solutions of Embodiment 2 and Embodiment 3 can achieve the cleaning effect; Embodiment 4 can achieve a good cleaning effect, but the starting speed is slow; the starting speed of Embodiment 5 is faster than that of Embodiment 4, and the cleaning effect is very good, but the speed may slow down after uniform motion, which will affect the cleaning rate and coverage rate to a certain extent; Embodiment 6 can increase the jet distance of the water flow and improve the persistence of power compared with Embodiment 5, and can greatly improve the cleaning rate and coverage rate.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended 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 shall 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.
