Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

As shown in fig. 1, the present embodiment provides a cleaning apparatus 100, the cleaning apparatus 100 includes a main body 10, a tub 20 and a vacuum motor 30, and the sewage recovery efficiency can be improved and the residual sewage in the cleaned area can be reduced. Here, the washing device may be configured to be a washing apparatus in a corresponding form according to the functional requirements of different application scenarios to perform different cleaning functions, which is not limited in the embodiment of the present application. Here, the X direction, the Y direction, and the Z direction may be defined as follows. The X direction is a forward direction of the main body 10, the Y direction is a width direction of the main body 10, the X direction and the Y direction are orthogonal directions in a horizontal plane, and the Z direction is a vertical extension direction of the main body 10.

The main body 10 is provided with a suction port 11 and a fluid passage 12, the suction port 11, the fluid passage 12 and an air inlet end of the slop pail 20 are sequentially connected, an air outlet end 21 of the slop pail 20 and an air inlet end 31 of the vacuum motor 30 are adjacently arranged and connected with each other, and further, the air outlet end 21 of the slop pail 20 and the air inlet end 31 of the vacuum motor 30 are directly connected. Thus, the suction port 11, the fluid passage 12, the slop pail 20 and the air inlet end 31 of the vacuum motor 30 can be sequentially communicated, the vacuum motor 30 can enable the suction port 11 to form negative pressure, so that air on the surface of a cleaned area is communicated with sewage, the sewage is sucked from the suction port 11 under the negative pressure and enters the slop pail 20 through the fluid passage 12, the slop pail 20 can separate water from the sewage, the sewage is retained in the slop pail 20, and the air is discharged into the vacuum motor 30 through the air outlet end 21 of the slop pail 20 and the air inlet end 31 of the vacuum motor 30, so that the sewage suction process is realized.

In the related art, the air inlet end 31 of the vacuum motor 30 of the cleaning machine and the air outlet end 21 of the slop pail 20 need to be connected through a long hose, and the hose is easy to bend. Therefore, the air flow of the vacuum motor 30 and the sewage bucket 20 has larger pipeline resistance, and the phenomena of unsmooth air flow and even pipe blockage and flow cutoff are easy to occur; accordingly, the vacuum motor 30 cannot secure a negative pressure required for the suction port 11, so that the suction force of the suction port 11 is insufficient and the suction flow rate of the suction port 11 is reduced. Because the cleaning machine needs to recover sewage in the moving process, the sewage cannot be recovered in time easily due to the low sewage suction flow of the suction port 11, and more residues of the sewage are generated on the ground or a carpet.

According to the cleaning device 100 provided by the embodiment of the application, the air inlet end 31 of the vacuum motor 30 and the air outlet end 21 of the sewage bucket 20 can be adjacently arranged and connected with each other or directly connected with each other, and the air inlet end 31 and the air outlet end 21 are not required to be connected through a pipeline or only a pipe fitting with a short length, so that the air flow between the sewage bucket 20 and the vacuum motor 30 is smooth, unsmooth air inlet caused by the bent layout of the pipeline is avoided, and sufficient pressure difference between the suction port 11 and the external air environment and high dirt suction flow of the suction port 11 are ensured; thus, the suction port 11 can recover sewage in time during the moving process of the cleaning device 100, thereby improving the sewage recovery efficiency and reducing the sewage residue in the cleaned area.

As shown in fig. 1-2, in some embodiments, the axial direction of the vacuum motor 30 may be parallel to the advancing direction of the main body 10, the air inlet end 31 of the vacuum motor 30 is disposed on one side of the vacuum motor 30 in the advancing direction, the air inlet end 31 is opened upward and can be directly connected to the air outlet end 21 of the slop pail 20, that is, the air inlet end 31 of the vacuum motor 30 is disposed below the air outlet end 21, here, the air inlet end 31 of the vacuum motor 30 may have a bent pipe structure to be directly connected to the air outlet end 21 of the slop pail 20, the bent pipe structure of the air inlet end 31 connects the axial air inlet of the vacuum motor 30 and the air outlet end 21 of the slop pail 20, and the axial air inlet of the vacuum motor 30 is disposed on one side of the vacuum motor 30 facing the advancing direction along the axial direction. In another embodiment, an elbow structure may be disposed at the air outlet end 21 of the slop pail 20 to directly connect with the axial air inlet of the vacuum motor 30. Compared with the arrangement mode that the axial direction of the vacuum motor is perpendicular to the advancing direction of the main body in the related art, the arrangement mode can shorten the distance between the air outlet end 21 of the sewage bucket 20 and the axial air inlet of the vacuum motor 30, and the air outlet end 21 is directly connected with the air inlet end 31, so that the complex pipeline trend is avoided, the loss of air suction air pressure is small, and the sewage recovery rate is improved. In addition, the slop pail 20 can be disposed above the vacuum motor 30, improving space utilization efficiency on the main body 10.

In some examples, the suction port 11 may be provided at a front side region of the main body 10 in the advancing direction thereof, and the air intake end 31 of the vacuum motor 30 may be provided at a front end of the vacuum motor 30 in the advancing direction of the main body 10. In other examples, the suction port 11 may be provided at a rear side region of the main body 10 in the advancing direction thereof, and the air intake end 31 of the vacuum motor 30 may be provided at a rear end of the vacuum motor 30 in the advancing direction of the main body 10. On one hand, the arrangement mode can ensure that the air inlet end 31 of the vacuum motor 30 is closer to the suction port 11, the distance between the air inlet end 31 of the vacuum motor 30 and the suction port 11 is shortened, and the vacuum motor 30 can ensure that the suction port 11 and the external air environment have sufficient pressure difference, so that the suction port 11 has higher dirt suction flow; on the other hand, compared with the arrangement mode that the axial direction of the vacuum motor is perpendicular to the advancing direction of the main body in the related art, the arrangement mode can fully utilize the space on the main body 10 along the advancing direction to carry out structural layout, reduce the space occupation on the main body 10 along the two opposite sides of the width direction, compress the width dimension of the main body 10 or the height dimension on the two opposite sides of the width direction, and increase the passing capacity of the main body 10 under different environments.

As shown in FIGS. 1-5, in some embodiments, the cleaning device 100 may further include a heating blower assembly 40. The heating and air-out assembly 40 may include an air-out housing 41 and a heater 42 disposed on the air-out housing 41, one side of the air-out housing 41 is connected to the air outlet 32 of the vacuum motor 30, and the other side forms an air-out portion 411, and the heater 42 may be disposed between the air outlet 32 of the vacuum motor 30 and the air-out portion 411.

After the air is discharged into the vacuum motor 30 through the air outlet end 21 of the slop pail 20 and the air inlet end 31 of the vacuum motor 30, the air can further enter the air outlet housing 41 through the air outlet 32 of the vacuum motor 30. The heater 42 on the air outlet casing 41 can generate heat to heat the air to form hot air, and the hot air is blown to the surface of the cleaned area through the air outlet part 411 of the air outlet casing 41 to promote the accelerated volatilization of the moisture on the surface of the cleaned area, so that the cleaned area can be quickly dried, and the breeding of bacteria and peculiar smell caused by the long-time residual moisture is avoided.

In some examples, an air outlet 32 may be formed on an outer peripheral surface of an end of the vacuum motor 30 near the air inlet end 31, and an air outlet cover 33 may be disposed at the air outlet 32. The air outlet cover 33 is connected with the air outlet casing 41, the air outlet cover 33 can be used for exhausting air towards the bottom of the main body 10 along the height direction of the main body 10, and the circumferential air exhausted from the air outlet 32 is vertically and downwardly guided to the heating air outlet assembly 40. Here, the orthographic projection of the air outlet surface of the air outlet cover 33 on the plane of the air outlet shell 41 can cover the air outlet shell 41, so that a larger air exchange area is ensured between the air outlet cover 33 and the air outlet shell 41. Or, the orthographic projection of the air outlet surface of the air outlet cover 33 on the plane of the air outlet shell 41 covers the heater 42, so that the wind energy from the main motor flows through the heater 42 on the complete section of the heater 42.

Here, the installation position of the heating and air-out assembly 40 may be determined according to actual needs, and the embodiment of the present application does not limit this. In some examples, the air outlet 411 of the heating and air-out assembly 40 is located at a side of the main body 10 facing the cleaned area, that is, at the bottom of the main body 10, so that the air outlet 411 may be located between the main body 10 and the cleaned area, and blows hot air to the cleaned area rapidly and directly, so that the cleaned area can be dried rapidly. In some examples, the main body 10 may be provided with a roll brush mounting part 13, and the roll brush 50 may be provided to the roll brush mounting part 13. Here, the roller brush 50 may be used to scrub the surface of the floor or carpet to be cleaned using various types of roller type brush bodies suitable for rotation according to the application requirements of the cleaning apparatus 100.

Correspondingly, along the advancing direction, the air outlet portion 411 of the heating air outlet assembly 40 is located behind the rolling brush installation portion 13, so that the air outlet portion 411 of the heating air outlet assembly 40 directly dries the area cleaned by the rolling brush 50. In addition, the air outlet 411 of the heating air outlet assembly 40 may be located between the motor 30 and the roller brush, so as to more conveniently utilize the air outlet of the motor 30 to dry after cleaning in terms of structural arrangement. Here, the air outlet portion 411 of the heating air outlet assembly 40 can deflect in the direction away from the rolling brush mounting portion 13, on one hand, the amount of hot air blown to the rolling brush 50 in the air outlet portion 411 can be reduced, structural deformation and service life loss of the rolling brush 50 due to overheating are avoided, on the other hand, most of the hot air in the air outlet portion 411 can be blown to the area cleaned by the rolling brush 50, and the drying rate is improved.

In a preferred embodiment, referring to fig. 1 and 2, the projection of the air inlet end 31 of the motor 30 and the projection of the heating air outlet assembly 40 on the horizontal plane are at least partially overlapped, or the axis of the air inlet end 31 of the motor 30 and the axis of the heating air outlet assembly 40 are overlapped, and the axis direction is a direction perpendicular to the horizontal plane, so that the structure of the motor 30, the slop pail 20 and the heating air outlet assembly 40 is more compact, and the arrangement of the components is more reasonable and efficient. That is, the projection of the air outlet end 21 of the slop pail 20 and the heating air outlet assembly 40 on the horizontal plane at least partially coincides, or the axis of the air outlet end 21 of the slop pail 20 coincides with the axis of the heating air outlet assembly 40. In another embodiment, the length of the projection of the bent pipe connecting the axial air inlet of the motor 30 and the air inlet end 31 of the motor 30 on the horizontal plane is equal to the length of the air outlet end 21 of the slop pail, so that the arrangement of the slop pail and the motor can be made compact by the maximum limitation.

Here, as shown in fig. 5, an orthographic projection of the air outlet portion 411 of the heating and air-out assembly 40 in a first plane parallel to the advancing direction of the main body 10 and perpendicular to the extending direction of the rolling brush mounting portion 13 may be referred to as a first projection; when the roll brush 50 is mounted on the roll brush mounting part 13, the axial direction of the roll brush 50 coincides with the extending direction of the roll brush mounting part 13, and accordingly, the firstThe plane is also perpendicular to the axial direction of the roller brush 50. In some examples, an angle (hereinafter, referred to as a first angle) a between a top of the first projection or a tangent of the top and the advancing direction of the main body 10₁Can be set at 5 ° to 20 °, for example 5 °, 5.5 °, 6 °, 6.4 °, 6.7 °, 7 °, 7.3 °, 7.5 °, 8 °, 8.2 °, 8.6 °, 9 °, 9.5 °, 10 °, 10.5 °, 11 °, 11.5 °, 12 °, 12.5 °, 13 °, 13.5 °, 14 °, 14.5 °, 15 °, 15.5 °, 16 °, 16.5 °, 17 °, 17.5 °, 18 °, 18.5 °, 19 °, 19.5 °, 20 °, or the like. Within this angle range, on one hand, the air outlet portion 411 has a sufficient deflection angle with respect to the roller brush mounting portion 13, the amount of hot air blown to the roller brush 50 in the air outlet portion 411 is small, and heat loss of the roller brush 50 can be reduced better, and on the other hand, the main area of the air outlet portion 411 can be over against the area scrubbed by the roller brush 50, and most of the hot air in the air outlet portion 411 can be blown to the area scrubbed by the roller brush 50 relatively directly, so that insufficient amount of hot air blown to the area scrubbed by the roller brush 50 due to an excessively large deflection angle is avoided, and loss of hot air and drying heat energy is reduced. Illustratively, the first included angle may be 7 ° to 10 °, so that the above effect is significant, and preferably, the first included angle is 8 °.

According to the shape of the air outlet part 411, the shape of the first projection is correspondingly different; accordingly, the first included angle may be an included angle between the top of the first projection and the advancing direction of the main body 10, or an included angle between a tangent of the top of the first projection and the advancing direction of the main body 10. Illustratively, the first projection may have an arc configuration, and the first included angle is an included angle between a tangent line of the arc configuration at a top portion thereof and the advancing direction of the main body 10. As another example, the first projection may include a first arc segment, a straight segment, and a second arc segment that are connected in sequence and smoothly, and a top of the first projection is located on the straight segment, so that the first included angle is an included angle between the straight segment and the advancing direction of the main body 10.

In some examples, the air outlet portion 411 of the heating and air-out assembly 40 may have a long strip configuration, and the extending direction of the air outlet portion 411 is the length direction. Here, the length direction of the air outlet portion 411 may be parallel to the extending direction of the rolling brush mounting portion 13, so that the air outlet portion 411 can better match the axial size of the rolling brush 50, increase the coverage area of the rolling brush 50 after being cleaned along the axial direction of the rolling brush 50, and improve the drying efficiency.

As shown in fig. 6, in some examples, the air outlet portion 411 has two side walls 411b oppositely disposed along a width direction of the main body 10, wherein at least one side wall 411b is configured to guide air in a direction away from the other side wall 411b, and the width direction of the main body 10 is perpendicular to an advancing direction of the main body 10. For example, of the two side walls 411b of the air outlet portion 411 disposed opposite to each other in the width direction of the main body 10, only one side wall 411b is configured to discharge air in a direction away from the other side wall 411b, and the other side wall 411b is not configured as such. Further exemplarily, fig. 6 is a projection of the two side walls 411b on the YZ plane, and in the two side walls 411b of the air outlet portion 411 disposed opposite to each other in the width direction of the main body 10, any one side wall 411b is configured to be discharged in a direction away from the other side wall 411 b.

In this way, in the vicinity of the side wall 411b configured as above, hot air can be blown in a direction away from the other side wall 411b by the air guiding function of the side wall 411b, and the coverage area of the hot air in the width direction of the main body 10 is increased, so that one or both sides of the cleaned area in the width direction of the main body 10 can be dried by the hot air, thereby improving the drying efficiency and enhancing the drying effect. In addition, on the premise that the axial length of the rolling brush 50 is not changed, since the air supply range of the air outlet portion 411 in the width direction of the main body 10 is large, the size of the air outlet portion 411 in the width direction of the main body 10 can be properly reduced, so that the structure is small and the material cost is low.

Here, an angle between the extending direction of the side wall 411b arranged as above and the width direction of the main body 10 may be referred to as an air guide angle of the side wall 411 b; the extending direction of the sidewall 411b refers to a direction from one end of the sidewall 411b near the heater 42 to the other end. The wind guiding angle can be determined according to actual needs, and the embodiment of the application is not limited to this. Illustratively, the extending direction of the side wall 411b and the main body 10 are configured as aboveThe angle (hereinafter referred to as the second angle) a between the width directions₂The acute angle is preferably 45 ° to 85 °, such as 45 °, 48 °, 51 °, 55 °, 57 °, 60 °, 62 °, 65 °, 70 °, 75 °, 80 °, or 85 °. In this angular range, the side wall 411b has a large air blowing angle in the width direction of the main body 10, so that the air outlet portion 411 has a large air blowing range of hot air.

Illustratively, an angle a between the extending direction of at least one side wall 411b and the width direction of the main body 10₂Is 55 to 65 degrees. In this angle range, this side lateral wall 411b except that having great air feed angle, on the other hand can be so that air-out portion 411 has better structural strength and reliability, and the third aspect can be so that air-out portion 411 easily carries out the mould shaping, reduces and makes the degree of difficulty and cost.

As shown in fig. 3, in some examples, the air outlet portion 411 may include a plurality of air outlet holes 411a arranged in an array to increase air outlet guiding effect on hot air and reduce air outlet noise. Here, the plurality of outlet holes 411a may be arranged in a regular array according to different arrays, and may be one or more of a linear array, an annular array, a square array, a circular array, and the like, which is not limited in this embodiment of the present application.

As shown in fig. 3 and 7, the air outlet portion 411 has two opposite ends along the width direction of the main body 10, and an area between the two opposite ends is a middle area of the air outlet portion 411, wherein the air outlet hole 411a at least at one end is configured to output air in a direction away from the other end, and the air outlet hole 411a in the middle area is configured to output air vertically downwards; of course, the air outlet 411 may not have the above-mentioned middle area. For example, of the opposite ends of the air outlet portion 411 in the width direction of the main body 10, only the air outlet hole 411a of one end is configured to discharge air in a direction away from the other end, and the air outlet hole 411a of the other end is not so configured. For another example, of the opposite ends of the air outlet portion 411 in the width direction of the main body 10, the air outlet hole 411a of either end is configured to discharge air in a direction away from the other end. Here, at one end configured as above, there may be one or more air outlet holes 411a configured to discharge air in a direction away from the other end. Specifically, the air outlet portion 411 has a left end and a right end along the width direction of the main body 10, the left air outlet hole 411a discharges air in a direction away from the right end, and the right air outlet hole 411a discharges air in a direction away from the left end. In this way, in the outlet holes 411a configured as above, hot air may be blown in a direction away from the other end, increasing a coverage area of the hot air in the width direction of the main body 10, so that one or both sides of the cleaned area in the width direction of the main body 10 can be dried by the hot air, improving drying efficiency, and enhancing drying effect. In addition, on the premise that the axial length of the rolling brush 50 is not changed, since the air supply range of the air outlet portion 411 in the width direction of the main body 10 is large, the size of the air outlet portion 411 in the width direction of the main body 10 can be properly reduced, so that the structure is small and the material cost is low. As described above, at least one side wall 411b of the two side walls 411b of the air outlet portion 411 that face each other in the width direction of the main body 10 may be arranged to guide air in a direction away from the other side wall 411 b.

Illustratively, an angle a between the air outlet direction of the air outlet 411a at least at one end and the width direction of the main body 10₃Is 45 degrees to 85 degrees (namely the air outlet angle of the air outlet hole 411 a), such as 45 degrees, 48 degrees, 51 degrees, 55 degrees, 57 degrees, 60 degrees, 62 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees or 85 degrees, and the like. In this angle range, the air outlet 411a has a large air supply angle in the width direction of the main body 10, so that the air outlet 411 has a large hot air supply range. Illustratively, for the air outlet 411a located at the end in the width direction of the main body 10, the second included angle a₂May be an included angle a between the air outlet direction of the air outlet 411a at least one end and the width direction of the main body 10₃。

Illustratively, an angle a between the air outlet direction of the air outlet 411a at least at one end and the width direction of the main body 10₃Is 55-65 degrees. In this angle range, the air outlet 411a has a larger air supply angle, on the other hand, the air outlet 411 has better structural strength and reliability, and the third aspect can make the air outlet 411 easily perform die forming, reduce the manufacturing difficulty and formThe method is as follows.

Illustratively, the ratio of the sum of the flow areas of the air outlet holes 411a at the one end configured as above to the flow area of the air outlet portion 411 in the width direction of the main body 10 is a predetermined value, which can be determined according to actual needs, and this is not limited in the embodiments of the present application, and preferably, the predetermined value is not less than 1/4 to ensure a sufficient air supply area, and the predetermined value is not more than 1/2. For example, of opposite ends of the air outlet portion 411 in the width direction of the main body 10, the air outlet hole 411a of either end is configured to outlet air in a direction away from the other end; the sum of the flow areas of the outlet holes 411a at either end accounts for 1/3 of the flow area of the outlet portion 411, and the sum of the flow areas of the outlet holes 411a in the middle region between the opposite ends accounts for 1/3 of the flow area of the outlet portion 411. For another example, the sum of the flow areas of the outlet holes 411a at either end accounts for 1/4 of the flow area of the outlet portion 411, and the sum of the flow areas of the outlet holes 411a in the middle region between the opposite ends accounts for 1/2 of the flow area of the outlet portion 411. For example, when the air outlet portion 411 has no middle region, the sum of the flow areas of the air outlet holes 411a at either end accounts for 1/2 of the flow area of the air outlet portion 411, the air outlet portion 411 is located at the left side in the middle as the air outlet hole at one end, the air outlet portion 411 is located at the right side in the middle as the air outlet hole at the other end, and the flow areas of the air outlet holes at both ends account for 1/2.

Exemplarily, the air outlet angle a of the air outlet 411a at one end₃Is a first value, and the air outlet angle a of the air outlet 411a at the other end₃The first value and the second value may be equal or unequal, and the first value and the second value may be a constant value or at least one of the first value and the second value may be gradually decreased in a direction away from the other end. For example, at one end configured as above, an angle a between the air outlet direction of the air outlet 411a and the width direction of the main body 10₃The air outlet angle of the air outlet hole 411a can be gradually increased along the direction of the middle area close to the air outlet portion 411. For example, of opposite ends of the air-out portion 411 in the width direction of the main body 10, an air-out hole 411a of either end is formedIs configured to wind in a direction away from the other end; the air outlet part 411 is located in the middle area along the width direction of the main body 10, and the included angle between the air outlet direction of the air outlet hole 411a and the width direction of the main body 10 can be 90 degrees; an included angle a between the air outlet direction of the air outlet 411a and the width direction of the main body 10 from the middle region to any one of the opposite ends₃May be tapered within the above-mentioned angular range.

For example, the air outlet hole 411a for discharging air in a direction away from the other end of the air outlet portion 411 may be formed as follows: the air outlet 411a has two side walls parallel to the air outlet direction, and the two side walls are disposed in an inclined manner, so that the air outlet direction of the air outlet 411a is far away from the other end of the air outlet 411, that is, an included angle between the two side walls and the width direction of the main body 10 is the same as the air outlet angle of the air outlet.
