In the related art, the laundry treating apparatus adopting the water-up and water-down method needs to drain the contaminated water out of the washing machine through the drain pump after the washing operation is completed. However, the drainage pump is often installed parallel to the ground, which prolongs the duration of gas-liquid mixing at the end stage of drainage, causes larger noise, and after the drainage pump finishes drainage, more sewage remains in the water pump, so that bacteria are easy to breed in the drainage pump

To solve the above technical problems, according to an embodiment of the present disclosure, there is provided a pump including: the water inlet device comprises a shell, wherein the outer surface of the shell is provided with a mounting surface, the shell comprises a first surface, and water entering the pump flows out of the pump after flowing through the first surface; the first surface of the housing is inclined in a gravitational direction with respect to a perpendicular direction to the mounting surface.

It should be understood that the embodiments of the present disclosure are not limited to the specific techniques and specific apparatus configurations employed by the laundry treatment device.

Fig. 1 is a schematic diagram illustrating a pump according to an exemplary embodiment. Fig. 2 is a schematic cross-sectional structure of a pump according to an exemplary embodiment. Fig. 3 is a schematic diagram of a front view of a pump according to an exemplary embodiment.

In some embodiments, as shown in fig. 1-3, the pump may include: a housing 1.

The housing 1 may be an outer shell of the pump, and other components of the pump may be accommodated in the housing 1 and provide support and fixing for other components of the washing machine.

The outer surface of the casing 1 may be provided with a mounting surface 2, and the mounting surface 2 may be one of the surfaces of the casing 1 having a connection structure, and the pump may be fixed to other objects through the mounting surface 2, thereby realizing the mounting and fixing of the pump.

The housing 1 may include a bottom portion, which may be a bottom end portion of the pump in a gravitational direction when the pump performs a water discharge operation, and a first face 3, which may be an inner surface of the bottom portion of the housing 1. When the pump performs the water draining operation, the first surface 3 may be a bottom surface in contact with water flow, and the water entering the pump flows out of the pump after flowing through the first surface.

The first face 3 may be inclined to the direction of gravity with respect to the perpendicular to the mounting face 2, which may allow the first face 3 to be angled from the horizontal when the mounting face 2 is mounted to an external vertical plane. This may allow the liquid to collect under gravity at the lower end of the housing 1 along the obliquely arranged first face 3 when less liquid is in the housing 1. The housing 1 may, for example, comprise a first end 11 with a higher level and a second end 12 with a lower level, and the liquid in the pump may spontaneously flow from the first end 11 to the second end 12 under gravity without resting on the first face 3. This can prevent that more liquid stays on the first surface 3 and cannot be discharged out of the pump, thereby reducing the liquid residue in the pump and preventing the interior of the pump from mildewing due to long-term sewage.

In addition, when the residual liquid in the pump is less, the liquid can spontaneously collect at the lower end of the shell 1, and the lower end of the shell 1 can be the second end 12 of the shell 1, so that the liquid can be discharged by the pump as soon as possible, the gas-liquid mixing time in the pump is reduced, and the working noise of the pump is reduced.

By tilting the first face 3 towards gravity, this may allow the first face 3 to be angled from the horizontal when the mounting face 2 is mounted to an external vertical plane. This can make when the liquid in casing 1 is less, and liquid can be under the action of gravity, and the first face 3 that sets up along the slope gathers in the lower one end of casing 1 to prevent that more liquid from stopping on first face 3 can't discharge the pump, thereby reduced the liquid residue in the pump, prevent that the pump is inside to be moldy because of long-term sewage that remains.

In addition, when the residual liquid in the pump is less, the liquid can be preferentially gathered at the lower end of the shell 1, so that the liquid can be discharged by the pump as soon as possible, the gas-liquid mixing time in the pump is reduced, and the working noise of the pump is reduced.

In other embodiments, the first face 3 may also be inclined in any direction less than ninety degrees from the direction of gravity.

In some embodiments, as shown in fig. 1-3, the housing 1 may include a first end 11 and a second end 12 opposite the first end 11. The first end 11 and the second end 12 may be both ends of the housing 1 in the length direction.

The housing 1 may include a first housing 21, a first cavity 211 may be formed in the first housing 21, the first cavity 211 may be a drainage cavity when the pump performs a drainage operation, and a liquid during the drainage operation may enter or leave the first cavity 211.

The housing 1 may include a second housing 22 connected to the first housing 21 along a length direction of the housing 1, and a second cavity 221 may be formed in the second housing 22, and the second cavity 221 may be a drainage cavity when the pump performs a drainage operation, and liquid during the drainage operation may enter or leave the second cavity 221. Wherein the first cavity 211 and the second cavity 221 may communicate with each other, and illustratively, a liquid may flow from the first cavity 211 to the second cavity 221.

The second housing 22 may be offset in the gravity direction with respect to the first housing 21, so that the second chamber 221 may be offset in the gravity direction with respect to the first chamber 211. This may enable the first cavity 211 and the second cavity 221 to form a stepped structure cavity, and when there is less liquid remaining in the pump, the liquid may be more concentrated in the second cavity 221, so that the pump may better drain the liquid out of the pump.

In some embodiments, as shown in fig. 1-3, the mounting surface 2 may be disposed at the first end 11.

In some embodiments, as shown in fig. 1-3, the pump may include: a water inlet 31 and a water outlet 32.

The water entering from the water inlet 31 flows through the first surface 3 and then flows out from the water outlet 32. The water inlet 31 may be a liquid inlet portion of the pump, and the water outlet 32 may be a liquid outlet portion of the pump, and illustratively, sewage may enter the pump via the water inlet 31 and flow within the pump to the water outlet 32 before exiting the pump via the water outlet 32.

The water inlet 31 may be provided in the first housing 21 adjacent the first end 11 of the housing 1, wherein the first end 11 of the housing 1 may be the end of the housing 1 having a higher level, which results in a higher level of the water inlet 31, thereby facilitating the entry of liquid from the water inlet 31 into the pump, reducing the liquid pressure that the liquid needs to overcome when there is more liquid in the pump from the water inlet 31 into the pump.

The water outlet 32 may be disposed in the second housing 22 and adjacent to the second end 12 of the housing 1, wherein the second end 12 of the housing 1 may be the end of the housing 1 having a lower level, which results in the water outlet 32 having a lower level, which may allow a portion of the liquid to spontaneously flow under the force of gravity to the water outlet 32 disposed adjacent to the second end 12, thereby facilitating the liquid exiting the pump from the water outlet 32, reducing the amount of residual water in the pump.

In some embodiments, as shown in fig. 1-3, the water inlet 31 may be at a higher level than the water outlet 32, so that liquid enters the pump from the water inlet 31 at a higher level and flows to the water outlet 32 at a lower level under the action of gravity, reducing the amount of residual water in the pump.

In some embodiments, as shown in fig. 1, the water inlet 31 may be provided at the upper half of the first housing 21. This may raise the level of the water inlet 31, thereby further reducing the pressure of the liquid that needs to be overcome by the liquid entering the pump from the water inlet 31.

And the water inlet 31 is provided at the upper half of the first housing 21 to reduce the backflow of the liquid in the pump from the water inlet 31.

In some embodiments, as shown in fig. 1 and 2, the water outlet 32 may include a first bottom surface 41 at the bottom end of the water outlet 32, and the first surface 3 may include a third bottom surface 43 disposed at the bottom end of the first housing 21 and a second bottom surface 42 disposed at the bottom end of the second housing 22, wherein the first bottom surface 41 of the water outlet 32 may be flush with the second bottom surface 42 of the second housing 22. This can avoid forming the groove structure between the first bottom surface 41 of the water outlet 32 and the second bottom surface 42 of the second housing 22, prevent the liquid from remaining in the groove structure and being unable to be discharged, further reduce the liquid remaining amount in the pump, and prevent the interior of the pump from mildewing due to long-term sewage remaining.

In some embodiments, the first bottom surface 41 of the water outlet 32 is lower than the second bottom surface 42 of the second housing 22, the first bottom surface 41 of the water outlet 32 and the second bottom surface 42 of the second housing 22 may form a stepped structure, which reduces the backflow of the liquid from the water outlet 32 into the second housing 22, and the end of the first bottom surface 41 of the water outlet 32 away from the second housing 22 may be inclined toward the gravity direction, so that the liquid flowing into the water outlet 32 may flow out through the water outlet 32 under the action of gravity, which reduces the backflow or residue of the liquid in the water outlet 32, further reduces the residue of the liquid in the pump, and prevents the interior of the pump from mildewing due to long-term sewage.

In some embodiments, as shown in fig. 1-3, the pump may include: an impeller 5 and a drive 6.

The impeller 5 may be disposed in the second chamber 221, and the impeller 5 may rotate in the second chamber 221, thereby driving the liquid in the second chamber 221 to rotate together and form a vortex. By rotation of the impeller 5, the liquid in the second chamber 221 can be discharged out of the pump through the water discharge port 32 during rotation with the impeller 5, and rotation of the impeller 5 can cause a change in the gas pressure and the liquid pressure in the pump, so that the pump can suck the liquid from the water inlet 31 and discharge the liquid from the water outlet 32 by the pressure difference.

Because the second cavity 221 and the first cavity 211 form a step structure cavity, when the residual liquid in the pump is less, the liquid can be converged in the second cavity 221 instead of being uniformly distributed on the inner surface of the shell 1, so that the impeller 5 is arranged in the second cavity 221, the impeller 5 can stir the liquid converged in the second cavity 221, so that the residual liquid is discharged in a small amount, the residual liquid in the pump is further reduced, the mildewing of the interior of the pump due to long-term sewage is prevented, the gas-liquid mixing time in the pump is also reduced, and the working noise of the pump is reduced.

A drive means 6 may be provided at the second end 12 of the housing 1, the drive means 6 being adapted to power the impeller 5 so as to drive the impeller 5 in rotation.

In some embodiments, as shown in fig. 1, the extending direction of the water outlet 32 may be in the tangential direction of the rotation track of the impeller 5, which may exemplarily make the liquid rotating with the impeller 5 be thrown into the water outlet 32 by the impeller 5 at a certain speed, so as to enhance the water draining effect of the impeller 5, further reduce the liquid residue in the pump, prevent the interior of the pump from mildewing due to long-term sewage, and further reduce the gas-liquid mixing time in the pump, thereby reducing the working noise of the pump.

In some embodiments, the axial direction of the rotation of the impeller 5 may be parallel to the horizontal plane, so that the liquid vortex is more stable and easy to control, the drainage effect of the impeller 5 is enhanced, the liquid residue in the pump can be further reduced, the pump is prevented from mildewing due to long-term sewage left in the pump, and the gas-liquid mixing time in the pump can be further reduced, so that the working noise of the pump is reduced.

In some embodiments, as shown in fig. 2, the length L of the first face 3 may be 58mm to 68mm. Illustratively, the length L of the inner surface of the housing 1 in the axial direction may be 63mm.

By shortening the length L of the first surface 3, the sum of the volumes of the first cavity 211 and the second cavity 221 can be reduced, so that the total internal water volume of the pump during the water discharge operation is reduced, and the residual internal water volume after the water discharge operation is completed can be reduced by reducing the total internal water volume.

And through shortening the length L of the first surface 3, the total area of the inner surface can be reduced, namely the area of the wall of liquid can be reduced, so that the residual water quantity adhered to the inner surface of the shell 1 is reduced, and the internal residual water quantity after the pump finishes the water discharge operation is further reduced.

By shortening the length L of the first face 3, the space required for installation of the pump can be reduced, and the installation space can be saved for installation of other components, thereby facilitating the internal design of the laundry treating apparatus.

In some embodiments, as shown in fig. 3, the first face 3 may have an angle of 4 ° to 5 ° with respect to the perpendicular to the mounting surface 2, which may allow the first face 3 to have an angle of 4 ° to 5 ° with respect to the horizontal plane when the housing 1 is mounted on a vertical plane through the mounting surface 2. If the included angle is smaller than 4 °, the inclination of the inner surface of the casing 1 is too small, and the residual water in the pump is more likely to stay on the inner surface of the casing 1 by its own tension and viscosity, so that the residual water in the pump cannot be significantly reduced. Therefore, the included angle is set to be 4-5 degrees, the size of the installation space required by the pump can not be obviously increased in the gravity direction, and when the liquid in the shell 1 is less, the liquid can be converged at the lower end of the shell 1 along the inclined first surface 3 under the action of gravity, so that more liquid is prevented from staying on the first surface 3 and can not be discharged out of the pump, the liquid residue in the pump is reduced, and the mildewing of the pump due to long-term sewage is prevented.

In other embodiments, the contained angle can be greater than 5, through making the angle of contained angle bigger to make the gradient of the internal surface of casing 1 increase, thereby make liquid can be better under the action of gravity, assemble in the lower one end of casing 1 along the first face 3 that the slope set up, prevent that more liquid from stopping and can't discharge the pump machine on first face 3, further reduced the liquid residue in the pump machine, prevent that the pump machine is inside to be moldy because of long-term sewage that remains.

The specific angle setting of the included angle can be determined according to the available installation space of the clothes treating apparatus, and the larger the available installation space is, the larger the included angle can be.

Based on the same conception, the embodiments of the present disclosure also provide a laundry treating apparatus.

The clothes treating apparatus may be clothes treating apparatus such as washing machine, clothes dryer or washing and drying machine, and may be any electric apparatus having a clothes treating function.

In other embodiments, the housing 7 may include an inclined surface, which may be inclined with respect to the direction of gravity. The mounting surface 2 of the pump can be arranged on the inclined surface of the housing 7, and by adjusting the included angle, the inner surface of the housing 1 can be inclined relative to the horizontal surface in the gravity direction after the pump is mounted on the inclined surface.

According to the embodiment of the disclosure, the first face 3 of the casing 1 is inclined relative to the mounting face 2, so that an included angle is formed between the first face 3 of the casing 1 and the horizontal plane, liquid in the pump can be converged in the lower second cavity 221 of the casing 1 under the action of gravity and is concentrated around the impeller 5, the impeller 5 can well discharge the participating water, liquid residues in the pump are reduced, gas-liquid mixing time of the pump is further reduced, and working noise of the pump is reduced.
