Description

Drum washing machine

Technical Field

The application relates to the technical field of washing machines, in particular to a drum washing machine.

Background

The washing machine is a cleaning appliance for washing laundry using an electric power generating mechanical action, and in order to save labor, the washing machine may be used instead of a user to perform a washing operation. The washing machine may be classified into pulsator washing machine and drum washing machine. Wherein, the barrel body of the pulsator washing machine is perpendicular to the ground. In the process of washing clothes by using the pulsator washing machine, the pulsator arranged at the bottom of the barrel body can be used for driving water flow to move by forward or reverse rotation. In this way, the moving water flow drives the clothes to turn over, so that friction is carried out between the clothes and the barrel wall, and dirt is removed under the action of the detergent.

When the pulsator washing machine is used for washing clothes, the pulsator washing machine mainly uses water flow to lift the clothes, so that the water consumption of the pulsator washing machine is large. The drum washing machine has smaller water consumption, and can solve the problem of large water consumption of the pulsator washing machine. In the process of washing clothes by using a drum washing machine, the basic principle is that the physical property of water is utilized, and when the drum washing machine is used for washing the clothes, the surface tension of the water and the fluidity of the water can be utilized, and the clothes are continuously rolled in the water, so that stains on the clothes are dissolved or washed away.

However, since the drum washing machine has less operations such as rubbing during washing, for example, in the process of washing laundry using the drum washing machine, the laundry is merely tumbled back and forth in the washing machine, and stains on a portion of the laundry may be difficult to wash, and the stains on the laundry may not be cleaned by the tumbling motion alone. Thus, washing laundry by the drum washing machine may cause some laundry to be not washed cleanly, that is, the drum washing machine has poor cleaning effect.

Disclosure of Invention

Some embodiments of the present application provide a drum washing machine to solve the problem of poor cleaning effect of the drum washing machine.

Some embodiments of the present application provide a drum washing machine, including:

the central axis of the inner barrel is obliquely arranged along the horizontal direction, and the outer contour of the inner barrel is circular; therefore, when the drum washing machine rotates, the collision force of clothes on the inner wall of the drum along the vertical direction is larger, and when the clothes drop from the inner wall of one side or are beaten to the inner wall of the opposite side by the washing machine, the dropping height between the clothes and the drum washing machine is also increased, so that the friction force between the clothes and the drum washing machine can be further improved, and therefore, the inclined inner drum can improve the cleaning force of the drum washing machine for cleaning the clothes;

the inner barrel rear cover is buckled on the inner barrel, a plurality of water-shifting ribs are arranged on the inner barrel rear cover at intervals, each water-shifting rib comprises an upstream surface and a back surface, the upstream surface and the back surface are arc-shaped surfaces, and the upstream surface and the back surface are respectively arranged on two sides of each water-shifting rib; the connection mode of the inner barrel rear cover and the inner barrel is not limited to buckling, and can be connected in a bolt mode and the like, and the specific mode is not limited in the application. When the drum washing machine rotates, the water-shifting rib on the rear cover of the inner barrel also rotates along with the drum washing machine, and a part of water flow in the washing machine can upwards rush up through the upstream surface and the downstream surface of the water-shifting rib, so that the water flow intensity flowing in the washing machine can be enhanced, and the cleaning force is improved. Meanwhile, as the water-shifting ribs are of the convex structures, the friction force between the water-shifting ribs and clothes can be enhanced, and the cleaning force for cleaning the clothes can be further improved.

The lifting ribs are arranged on the inner wall of the inner barrel at intervals, and at least one lifting rib protrusion is arranged on each lifting rib. Therefore, the lifting rib bulges can further lift friction force among clothes, the inner barrel and the lifting rib, and achieve the effect of rubbing the clothes, so that the lifting rib bulges of the lifting rib can also promote the cleaning effect of the drum washing machine for washing the clothes. The quantity that promotes the muscle setting can be set according to actual demand. In the process of washing laundry using the drum washing machine, the drum washing machine may rotate the inner tub by the motor, which is not shown, to generate centrifugal force. Like this, set up the hoisting rib on the inner tub and can constantly take up clothes, in-process that the inner tub rolled, the clothes that is taken to the eminence can drop under the effect of gravity, produces the effect of beating clothes from this, can get rid of the spot on the clothing, promotes the cleaning performance when drum type washing machine washs the clothing.

In some embodiments, the inner barrel has a diameter of 500 to 540 millimeters. In this way, the accommodating space formed by the inner tub and the rear cover of the inner tub is sufficient, and more clothes to be washed can be accommodated. Meanwhile, because the containing space is sufficient, when the drum washing machine rotates, the contact area of clothes and the detergent is larger, the contact is more uniform, and the cleaning effect of the clothes during washing can be further improved.

In some embodiments, the inner tub is uniformly distributed with a plurality of first through holes. Thus, after the washing of the laundry is completed, the moisture in the inner tub and the moisture in the laundry may be discharged through the first through hole.

In some embodiments, the first through hole is drop-shaped. Thus, the first through hole with the water drop shape can increase friction force between the clothes and the inner barrel, and the clothes can be cleaned more cleanly.

In some embodiments, the inner tub rear cover is provided with at least one rear cover protrusion. Therefore, the rear cover bulge can increase friction among clothes, between clothes and the inner barrel and between the clothes and the rear cover of the inner barrel, and increase friction force, so as to achieve the effect of rubbing the clothes, and therefore, the rear cover bulge of the rear cover of the inner barrel can improve the cleaning effect of the drum washing machine for washing the clothes.

In some embodiments, the inner tub rear cover is provided with a plurality of second through holes, and the second through holes are uniformly formed at both sides of the rear cover protrusion. Thus, after the washing of the laundry is completed, the moisture in the inner tub and the moisture in the laundry may be discharged through the second through hole.

In some embodiments, the outer contour of the inner tub rear cover is circular. The inner barrel and the inner barrel rear cover can form a containing space no matter the inner barrel rear cover is connected with the inner barrel in a buckling way or in a bolt way or in other ways. Thus, a user can place laundry to be washed in the accommodating space while washing the laundry with the drum washing machine.

In some embodiments, a plurality of third through holes are provided on the lifting rib. Like this, the third through-hole on the lifting rib can promote the washing effect of rivers to abluent clothing, through the high water permeability of third through-hole, and then promotes washing dynamics, promotion to abluent clothing cleaning effect.

In some embodiments, the lifting ribs snap onto the inner wall of the inner tub. Therefore, after the lifting ribs are buckled on the inner wall of the inner barrel, the lifting ribs can bring up clothes in the rotating process of the drum washing machine, so that the effects of stirring, rubbing and the like of the clothes are realized.

In some embodiments, the lifting rib is fixedly connected to the inner wall of the inner tub by a bolt. Therefore, after the lifting ribs are fixedly connected to the inner wall of the inner barrel through bolts, the lifting ribs can lift clothes in the rotating process of the drum washing machine, and the effects of stirring, rubbing and the like of the clothes are achieved.

According to the technical scheme, some embodiments of the present application provide a drum washing machine, which comprises an inner tub, an inner tub rear cover and at least one lifting rib. Wherein, the axis of interior bucket can be followed the horizontal direction slope and set up, and the outline of interior bucket is circular, and lid lock is on interior bucket behind the interior bucket, promotes the muscle interval setting and including the inner wall of bucket, is provided with at least one on the lifting rib and promotes the muscle arch. The inclined inner barrel can improve the friction force between clothes and the drum washing machine, so that the cleaning force of the drum washing machine for cleaning the clothes is improved, and the inner barrel and the rear cover of the inner barrel can form a containing space, so that a user can place the clothes to be cleaned in the containing space when the user uses the drum washing machine for cleaning the clothes.

Detailed Description

For purposes of clarity and implementation of the present application, the following description will make clear and complete descriptions of exemplary implementations of the present application with reference to the accompanying drawings in which exemplary implementations of the present application are illustrated, it being apparent that the exemplary implementations described are only some, but not all, of the examples of the present application.

It should be noted that the brief description of the terms in the present application is only for convenience in understanding the embodiments described below, and is not intended to limit the embodiments of the present application. Unless otherwise indicated, these terms should be construed in their ordinary and customary meaning.

The terms first, second, third and the like in the description and in the claims and in the above-described figures are used for distinguishing between similar or similar objects or entities and not necessarily for describing a particular sequential or chronological order, unless otherwise indicated. It is to be understood that the terms so used are interchangeable under appropriate circumstances.

The terms "comprises," "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a product or apparatus that comprises a list of elements is not necessarily limited to all elements explicitly listed, but may include other elements not expressly listed or inherent to such product or apparatus.

The washing machine is a cleaning appliance for washing laundry using an electric power generating mechanical action, and in order to save labor, the washing machine may be used instead of a user to perform a washing operation. In some embodiments, the washing machine may be classified into pulsator washing machine and drum washing machine. Wherein, the barrel body of the pulsator washing machine is perpendicular to the ground. In the process of washing clothes by using the pulsator washing machine, the pulsator arranged at the bottom of the barrel body can be used for driving water flow to move by forward or reverse rotation. In this way, the moving water flow drives the clothes to turn over, so that friction is carried out between the clothes and the barrel wall, and dirt is removed under the action of the detergent. However, when washing laundry using the pulsator washing machine, the pulsator washing machine mainly uses water current to lift the laundry, and thus the water consumption of the pulsator washing machine is large.

The drum washing machine has smaller water consumption, and can solve the problem of large water consumption of the pulsator washing machine. In some embodiments, the tub of the drum washing machine is parallel to the ground, and the motor rotates the tub to generate centrifugal force when washing clothes with the drum washing machine. In washing laundry using a drum washing machine, the basic principle thereof is to use the physical properties of water. When the drum washing machine washes clothes, the surface tension of water and the fluidity of water can be utilized, and the clothes continuously tumble in the water, so that stains on the clothes are dissolved or washed away.

However, since the drum washing machine has less operations such as rubbing during the washing process, a portion of the laundry may not be washed cleanly, that is, the drum washing machine has a poor cleaning effect. For example, in the process of washing laundry using a drum washing machine, the laundry tumbles back and forth only in the washing machine, and stains on part of the laundry may be difficult to wash, and the stains on the laundry cannot be cleaned only by the tumbling action.

Before the washing machine appears, the user adopts modes such as rubbing, beating, washing and the like to wash the clothes, so that the clothes can be washed cleanly. In some embodiments, the above-described washing manner may be emulated to the washing machine to enhance the cleaning degree and washing efficiency of the washing machine.

Based on the above-mentioned scene, some embodiments of the present application provide a drum washing machine, which can simulate operations such as rubbing and beating, so as to simulate the washing actions of users on the washing machine. Therefore, the drum washing machine can clean clothes more cleanly, so that manpower can be saved, and the cleaning efficiency of the drum washing machine is improved. Hereinafter, a drum washing machine in an embodiment of the present application will be described in detail with reference to the accompanying drawings and detailed description.

Fig. 1 is a schematic diagram of a split structure of each component of a drum washing machine according to some embodiments of the present application, and as shown in fig. 1, the drum washing machine may include an inner tub 01, an inner tub rear cover 02, and at least one lifting rib 03. The respective components are described in detail below.

The specific inclination angle can be set according to actual requirements, and specific numerical values are not limited in the application. The central axis of the inner tub 01 may be inclined at a predetermined angle in the horizontal direction, that is, the inner tub 01 is inclined, so that when the drum washing machine rotates, the collision force of laundry in the vertical direction on the inner wall of the tub is greater, and the falling height between the laundry is increased when the laundry falls from the inner wall of one side or is beaten to the inner wall of the opposite side by the washing machine, thereby further improving the friction between the laundry and the drum washing machine, and thus, the inclined inner tub 01 may improve the cleaning force of the drum washing machine for washing the laundry.

In order to accommodate laundry to be washed in the inner tub 01, in some embodiments, the drum washing machine inner tub is provided with a rear cover 02, and the rear cover 02 may be fastened to the inner tub 01, and an outer contour of the inner tub rear cover 02 may be circular. It should be understood that the connection manner of the inner tub rear cover 02 and the inner tub 01 is not limited to the fastening, and may be connected in the form of a bolt, etc., and the specific manner is not limited in this application. The inner barrel 01 and the inner barrel rear cover 02 can form a containing space no matter the inner barrel rear cover 02 and the inner barrel 01 are connected in a buckling manner or in a bolt manner or in other manners. Thus, a user can place laundry to be washed in the accommodating space while washing the laundry with the drum washing machine.

In order to enhance the cleaning effect of the drum washing machine when washing laundry, in some embodiments, the drum washing machine includes at least one lifting rib 03, the lifting rib 03 is disposed on an inner wall of the inner tub 01, and at least one lifting rib protrusion 031 is disposed on the lifting rib 03. Like this, lifting rib protrusion 031 can further promote the frictional force between clothing and clothing, clothing and interior bucket 01 and lifting rib 03, reaches the effect of rubbing the clothing, consequently, lifting rib protrusion 031 of lifting rib 03 can promote the cleaning performance of drum type washing machine washing clothing equally.

The number of the lifting ribs 03 can be set according to actual requirements, for example, the lifting ribs 03 can be set to 3, other numbers can be set, and the like. In the process of washing laundry using the drum washing machine, the drum washing machine rotates the inner tub 01 by a motor, which is not shown, to generate centrifugal force. Like this, set up in the lifting rib 03 on barrel 01 can take up the clothes constantly, in the in-process that barrel 01 rolled, the clothes that is taken to the eminence can drop under the effect of gravity, produces the effect of beating the clothes from this, can get rid of the spot on the clothing, promotes the cleaning performance when drum type washing machine washs the clothing.

In some embodiments, the lifting rib 03 may be fastened to the inner wall of the inner barrel 01, or may be fixedly connected to the inner wall of the inner barrel 01 through a bolt, which is not specifically limited in this application. No matter which way the lifting rib 03 is connected with the inner barrel 01, the lifting rib 03 can carry the clothes in the rotating process of the drum washing machine, so that the effects of stirring, rubbing and the like of the clothes are realized.

Fig. 2 is a schematic view of an inner tub structure of a drum washing machine according to some embodiments of the present application, as shown in fig. 2, in some embodiments, the inner tub 01 has a diameter of 500-540 mm, and may be 530 mm, for example. In this way, the accommodating space formed by the inner tub 01 and the inner tub rear cover 02 is sufficient, and more clothes to be washed can be accommodated. Meanwhile, because the containing space is sufficient, when the drum washing machine rotates, the contact area of clothes and the detergent is larger, the contact is more uniform, and the cleaning effect of the clothes during washing can be further improved.

With continued reference to fig. 2, in some embodiments, the inner tub 01 has a plurality of first through holes 011 uniformly distributed thereon. In this way, after the laundry washing is completed, the moisture in the inner tub 01 and the moisture in the clothes may be discharged through the first through-hole 011.

In order to enhance friction between laundry and the inner tub 01 in the drum washing machine, the first through-hole 011 may have a drop shape as shown in fig. 2 in some embodiments. Thus, the drop-shaped first through holes 011 can increase friction between laundry and the inner tub 01, and thus can clean the laundry more cleanly.

Fig. 3 is a schematic view of an inner tub rear cover structure of a drum washing machine according to some embodiments of the present application, as shown in fig. 3, in some embodiments, at least one rear cover protrusion 022 is provided on the inner tub rear cover 02. The number of the rear cover protrusions 022 is not limited in this application, and the number of the rear cover protrusions 022 may be 3 as shown in fig. 3 or may be other numbers. Thus, the rear cover protrusion 022 can increase friction between clothes and the clothes, friction between the clothes and the inner tub 01 and friction between the clothes and the inner tub rear cover 02, and friction force can be increased, so that the effect of rubbing the clothes can be achieved, and the rear cover protrusion 022 of the inner tub rear cover 02 can improve the cleaning effect of the drum washing machine for washing the clothes.

With continued reference to fig. 3, in some embodiments, the inner tub rear cover 02 is provided with a plurality of second through holes 023, and the second through holes 023 are uniformly disposed at both sides of the rear cover protrusion 022. In this way, after the washing of the laundry is completed, the moisture in the inner tub 01 and the moisture in the laundry may be discharged through the second through hole 023.

Fig. 4 is a schematic view of a water-drawing rib structure of a drum washing machine according to some embodiments of the present application, and in combination with fig. 3 and fig. 4, in some embodiments, a plurality of water-drawing ribs 021 may be disposed on a rear cover 02 of an inner tub at intervals, and the water-drawing ribs 021 may include an upstream surface 0211 and a downstream surface 0212. Wherein, the upstream face 0211 and the downstream face 0212 are both arc-shaped, and the upstream face 0211 and the downstream face 0212 are respectively arranged at two sides of the water-shifting rib 021. Thus, when the drum washing machine rotates, the water-shifting rib 021 on the inner barrel rear cover 02 also rotates, and a part of water flow in the washing machine can upwards rush up through the upstream surface 0211 and the downstream surface 0212 of the water-shifting rib 021, so that the water flow intensity of the water flowing in the washing machine can be enhanced, and the cleaning force is improved. Meanwhile, as the water-shifting ribs 021 are of the convex structure, the friction force between the water-shifting ribs and clothes can be enhanced, and the cleaning force for cleaning the clothes can be further improved.

Fig. 5 is a schematic structural diagram of a lifting rib of a drum washing machine according to some embodiments of the present application, as shown in fig. 5, in order to improve the washing effect of water flow on clothes when the drum washing machine washes the clothes, in some embodiments, a plurality of third through holes 032 may be provided on the lifting rib 03. The third through-hole 032 may be provided in a plurality, and the specific shape is not limited herein, and may be, for example, a circular shape. Like this, the third through-hole 032 on the lifting rib 03 can promote the washing effect of rivers to abluent clothing, through the high water permeability of third through-hole 032, and then promote the washing dynamics to abluent clothing, promote the cleaning effect to the clothing. The number of the third through holes 032 can be set according to actual requirements, for example, the number of the third through holes 032 can be adaptively increased or decreased, and the specific number is not limited in this application.

As can be seen from the above discussion, in the process of washing clothes by using the drum washing machine, clothes can be continuously carried up by the lifting ribs 03, and in the process of rolling the inner tub 01, the clothes carried to a high position by the lifting ribs 03 can fall under the action of gravity, so that the effect of beating the clothes is achieved, friction force between the clothes can be improved, stains on the clothes can be removed, and the cleaning effect of the drum washing machine when the clothes are washed is improved. In addition, the washing of the laundry can be realized through the high water permeability of the third through hole 032, thereby improving the washing effect of the laundry.

That is, in some embodiments of the present application, the action of manually washing laundry by a user may be simulated into the drum washing machine, and the inner tub 01 adopts a size of, for example, 530 mm while adopting an inclined design so that the laundry has a maximally defined drop height while rotating within the tub. The inner barrel rear cover 02 is provided with at least one rear cover bulge 022, the lifting rib 03 is provided with at least one lifting rib bulge 031, and the bulge parts of the rear cover bulge 022 and the lifting rib bulge 031 can increase friction force between clothes and between the clothes and the barrel body, so that the effect of rubbing the clothes is achieved. Meanwhile, the third through hole 032 on the lifting rib 03 can increase the effect of washing clothes by water flow, and the cooperation among the above components can enable the drum washing machine to simulate the mode of manually washing clothes by a user, so that the effect of integrating a whole set of processes of rubbing, beating, washing and the like into the drum washing machine is realized.

The diameter of the inner tub 01 is 500-540 mm, for example, a mode of combining a large tub diameter of 530 mm with an inclined tub is adopted, so that when the drum washing machine rotates, the collision force of clothes on the inner wall of the tub along the vertical direction is larger, and when the clothes fall from the inner wall of one side or are beaten to the inner wall of the opposite side by the washing machine, the falling height between the clothes and the inner wall of the opposite side is increased, thereby further improving the friction force between the clothes and the drum washing machine, and further improving the cleaning force of the drum washing machine for cleaning the clothes.

For another example, the first through hole of the inner tub 01 is in a drop shape, and the drop-shaped first through hole can increase friction between clothes and the inner tub, so that the clothes can be cleaned more cleanly. The inner barrel rear cover is provided with at least one rear cover bulge. Therefore, the rear cover bulge can increase friction among clothes, between clothes and the inner barrel and between the clothes and the rear cover of the inner barrel, and increase friction force, so as to achieve the effect of rubbing the clothes, and therefore, the rear cover bulge of the rear cover of the inner barrel can improve the cleaning effect of the drum washing machine for washing the clothes.

For another example, at least one lifting rib protrusion is arranged on the lifting rib. Therefore, the lifting rib bulges can further lift friction force among clothes, the inner barrel and the lifting rib, and achieve the effect of rubbing the clothes, so that the lifting rib bulges of the lifting rib can also promote the cleaning effect of the drum washing machine for washing the clothes.

Wherein, the upstream face 0211 and the downstream face 0212 are both arc-shaped, and the upstream face 0211 and the downstream face 0212 are respectively arranged at two sides of the water-shifting rib 021. The lifting rib 03 is arranged on the inner wall of the inner barrel 01. The inclined inner tub can raise the cleaning force of the drum washing machine to clean clothing, and the inner tub and the back cover may form one holding space for the clothing to be cleaned to be set inside.
