Description

Technical Field

[0001] The present invention belongs to the field of washing machines, and in particular, relates to a washing tub and a washing machine having the washing tub. Background Art

[0002] With the continuous development of science and technology, consumers have an increasing demand for large-capacity washing machines. As the capacity of washing machines increases, the overall size of washing machines will inevitably increase. Therefore, it is necessary to provide a small-volume, large-capacity washing machine. At the same time, in the existing washing machines, water is distributed in the rotating barrel and the water tub during washing, that is, water is also distributed between the water tub and the rotating barrel, and the water consumption is large. However, this part of water does not participate in the washing of clothes, resulting in a waste of water resources. In the existing washing machines, dirt is easily retained between the water tub and the rotating barrel, thereby breeding bacteria. Moreover, because there is water distributed between the water tub and the rotating barrel, a large amount of detergent is required, resulting in a waste of detergent, which is not conducive to cost saving.

[0003] Based on the above problems, a washing machine is proposed which omits the water holding tub and retains only the rotating tub. The rotating tub can hold washing water, and the inner wall of the washing tub is provided with a drainage channel. During dehydration, the rotating tub rotates so that the washing water enters the drainage channel and is discharged from the water outlet of the drainage channel. However, since the rotating tub rotates at a high speed at this time, the washing water is not easy to drop in the drainage channel, and the rotation speed of the rotating tub needs to be reduced to achieve the discharge of the washing water. This method causes greater loss of the motor and the motor is easily damaged.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing tub and a washing machine having the washing tub.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0042] Embodiment 1

[0043] like Figure 1-4,9 shows a washing bucket, the washing bucket 100 can hold washing water, including a barrel body 105 and a drainage channel arranged on the side wall of the barrel body 105 for discharging the washing water in the barrel body 105 during dehydration, the drainage channel has a water inlet 102 connected to the inside of the barrel body 105, and the barrel body 105 has a guide portion for guiding the washing water in the barrel body 105 into the water inlet 102 during dehydration.

[0044] At present, the hole-free inner barrel is designed with equal diameter in the circumferential direction. During the dehydration stage, the water is basically evenly distributed on the barrel wall with equal thickness under the action of high-speed centrifugation, which is not conducive to quickly draining the water in the inner barrel. By setting a guide part, the washing water can quickly enter the drainage channel from the water inlet 102 under the guidance of the guide part, so that the washing water in the barrel body 105 can be quickly discharged during dehydration, thereby improving the dehydration efficiency and dehydration effect and shortening the dehydration time.

[0045] The washing tub 100 is a tub without holes, and has a function of containing water during washing.

[0046] In a further solution, the guide portion is a variable diameter section 133 formed by gradually increasing the radius of the barrel body 105 along the rotation direction when the barrel body 105 is dehydrated, and the drainage channel is arranged on the variable diameter section 133, so that the washing water guided by the variable diameter section 133 enters the drainage channel from the water inlet 102.

[0047] The radius of the side wall of the barrel body 105 gradually increases along the rotation direction of the barrel body 105 when it is dehydrated to form a variable diameter section 133. Since the radius of the variable diameter section 133 gradually increases along the rotation direction of the barrel body 105 when it is dehydrated, the washing water moves rapidly along the inner wall of the variable diameter section to the larger radius under the action of centrifugal force. The drainage channel is set on the variable diameter section 133 to discharge the washing water guided by the variable diameter section out of the barrel body 105.

[0048] In a further solution, at least a section of the side wall of the barrel body 105 in the axial direction gradually increases in radius along the rotation direction of the barrel body 105 during dehydration to form a diameter-changing section 133 in the circumferential direction.

[0049] The washing water in the barrel body 105 first climbs upward along the inner wall of the barrel body 105 under the action of centrifugal force to reach the variable diameter section 133, then quickly moves along the variable diameter section 133 in the direction of increasing radius to the drainage channel, enters the drainage channel through the water inlet 102 and is discharged.

[0050] Solution 1: The radius of the side wall of the barrel body 105 increases synchronously from top to bottom along the rotation direction of the barrel body 105 to form a circumferential variable diameter section 133.

[0051] In this solution, the barrel body 105 changes synchronously from the upper end to the lower end, forming a diameter-changing section 133 with a large side wall area, so that the washing water can be quickly collected and discharged along the diameter-changing section.

[0052] The position of the water inlet in this structure is not restricted, and the water inlet can be oriented toward the rotation direction of the barrel body when it is dehydrated, that is, circumferential water inlet or radial water inlet.

[0053] Solution 2: At least the side wall of the barrel body 105 between the upper edge and the lower edge of the water inlet 102 gradually increases in radius along the rotation direction of the barrel body 105 when it is dehydrated to form the variable diameter section 133.

[0054] In this structure, the washing water in the barrel body 105 first climbs upward along the inner wall of the barrel body 105 under the action of centrifugal force to reach the variable diameter section 133, and then quickly moves along the variable diameter section 133 in the direction of increasing radius to reach the drainage channel. Since the variable diameter section 133 is located on the barrel body 105 between the upper edge and the lower edge of the water inlet 102, the washing water directly enters the drainage channel from the water inlet 102 and is discharged from the barrel body 105 through the drainage channel.

[0055] In a further solution, the barrel body 105 further has at least one connecting section 134 on the circumference, and the connecting section 134 is arranged at intervals with the reducing section 133. The two ends of the connecting section 134 are respectively connected to the reducing section 133 adjacent thereto to close the circumference of the barrel body 105. Since the radius of the reducing section 133 gradually increases, the two adjacent reducing sections 133 or the head and tail of the same reducing section 133 cannot be directly closed, and the circumference of the barrel body 105 is closed by providing the connecting section 134. The drainage channel is provided on the reducing section 133.

[0056] Solution 1: The variable diameter section 133 and the connecting section 134 are both one section, and the two ends of the connecting section 134 are respectively connected to the head and tail of the same variable diameter section 133 to close the circumference of the barrel body 105.

[0057] Solution 2: There are multiple diameter-reducing sections 133 and connecting sections 134, which are arranged at intervals, and the two ends of each connecting section 134 are respectively connected to the ends of the two diameter-reducing sections 133 connected thereto to close the circumference of the barrel body 105. This structure makes the barrel body 105 easier to balance.

[0058] In a further embodiment, the barrel body 105 has a plurality of diameter-reducing sections 133 in the circumference, and the plurality of diameter-reducing sections 133 are evenly distributed in the circumference of the barrel body 105. This makes the barrel body 105 more symmetrical and easier to balance when rotating.

[0059] The barrel body 105 has a plurality of diameter-reducing sections 133 in the circumference, and the ends with the smallest radius of all the diameter-reducing sections 133 are located on the same circumference, and the ends with the largest radius of all the diameter-reducing sections 133 are located on another circumference, so that the barrel body as a whole can be more easily balanced.

[0060] The radius changing rate of each diameter-changing section 133 is the same, so that the barrel body has better symmetry and is easier to balance.

The drainage channel is arranged on the inner wall of the variable diameter section 133, and the washing water is quickly guided to the drainage channel and enters the drainage channel from the water inlet 102 and is discharged from the barrel body 105.

[0095] Embodiment 5

[0096] like Figure 7-8 As shown, a washing tub 100 is provided, which can hold washing water. The side wall of the washing tub 100 has a drainage channel for draining the washing water in the washing tub 100 during dehydration. The drainage channel has a water guide to guide the washing water in the drainage channel to be quickly discharged.

[0097] The washing tub 100 can hold washing water. During dehydration, the washing tub 100 rotates at a high speed. The washing water moves upward along the inner wall of the washing tub 100 under the action of centrifugal force, and then enters the drainage channel. Due to the large centrifugal force, the washing water entering the drainage channel is difficult to be discharged along the drainage channel. If the washing water is discharged under the action of gravity by deceleration, long-term deceleration and acceleration will reduce the service life of the washing machine. The present invention guides the washing water entering the drainage channel by setting a water guide part, so that the washing water can be quickly discharged without slowing down, which is more economical.

[0098] This structure can be designed as a washing bucket with a water guide part on the basis of the barrel body having a guide part in the first to fourth embodiments. The guide part of the barrel body guides the washing water into the drainage channel to improve the dehydration effect. Furthermore, the drainage channel has a water guide part, which guides the washing water entering the drainage channel so that the washing water entering the drainage channel is quickly discharged. Of course, the drainage channel with a water guide part can also be used alone on the barrel body.

[0099] Furthermore, the drainage channel has a water inlet 102, a water outlet 103 and an outer wall 104 away from the axis of the washing tub, and the outer wall 104 of the drainage channel at least partially extends from the water inlet 102 to the water outlet 103 away from the axis of the washing tub to form a water guide.

[0100] At least a portion of the outer wall 104 of the drainage channel extends from the water inlet 102 to the water outlet 103 in a direction away from the axis of the washing tub to form a water guide portion, so that the radius of the end of the outer wall 104 close to the water inlet 102 is small, and the radius of the end close to the water outlet 103 is large. When the washing tub 100 rotates to dehydrate, the washing water enters the drainage channel from the water inlet 102 with a smaller radius and moves along the water guide portion with an increasing radius. The centrifugal force exerted on the washing water has a component in the direction of the water outlet 103, which accelerates the flow speed of the washing water and reaches the water outlet 103 for discharge. The structure is simple and more economical.

[0101] Preferably, the water inlet 102 is arranged at the upper part of the drainage channel, the water outlet 103 is arranged at the lower part of the drainage channel, and the outer side wall 104 of the drainage channel is inclined from top to bottom in a direction away from the axis of the washing tub to form a water guide portion.

[0102] Generally, the interior of the washing tub 100 is connected to the drainage channel through the water inlet 102, and the drainage channel is connected to the outside of the washing tub 100 through the water outlet 103. No other holes are provided on the side wall of the washing tub 100 except the water inlet 102 and the water outlet 103, so that the washing tub 100 can hold water.

[0103] The drainage channel can be formed in a variety of ways.

[0104] Solution 1: The washing bucket 100 includes a bucket body 105 and a water channel, the water channel is arranged on the side wall of the bucket body 105, the water channel and the side wall of the bucket body 105 together form a drainage channel, and the outer side wall 104 of the drainage channel is inclined from top to bottom in a direction away from the axis of the washing bucket to form a water guide. This solution facilitates cleaning of the interior of the drainage channel and is safer and more hygienic.

[0105] Solution 2: The washing tub 100 includes a tub body 105 and a drainage pipe, the drainage pipe is arranged on the side wall of the tub body 105, the interior of the drainage pipe has a channel for washing water to flow through to form a drainage channel, and the outer side wall 104 of the drainage pipe is inclined from top to bottom toward the outside of the tub body 105 to form a water guide. The drainage pipe is an independent drainage channel, which is convenient for installation, replacement and use.

That is, the barrel wall of the barrel body 105 opposite to the water channel is the outer side wall 104 of the drainage channel, and the barrel wall of the barrel body 105 opposite to the water channel is inclined from top to bottom toward the outer side of the barrel body 105 to form a water guide portion.

During dehydration, the washing water is mainly distributed on the bottom wall of the receiving chamber 106 under the action of centrifugal force. Since the bottom wall of the receiving chamber 106 is inclined from top to bottom toward the outside of the barrel body 105, the washing water drops rapidly and is discharged from the water outlet 103 at the bottom.

[0112] Preferably, the mounting plate is an arc-shaped plate, and the arc line is cocircular with the inner wall of the barrel 105 to reduce the wear on the clothes.

The concave cavity 107 of the cover body 101 is opposite to the opening of the accommodating cavity 106, and the cover body 101 is connected to the inner wall of the barrel body 105. This structure can increase the flow rate of the drainage channel by relatively arranging the concave cavity 107 of the cover body 101 and the accommodating cavity 106 of the barrel body 105, so that the washing water can be quickly discharged from the barrel body 105.

[0114] Furthermore, the water inlet 102 is arranged toward the rotation direction of the barrel body 105 during dehydration, so that the washing water can enter the drainage channel more easily.
