As shown in FIGS. 1 to 10, the washing tub 1 of the washing machine of the present invention is installed on the main body of the washing tub 1 and the top of the wall of the washing tub 1 to draw out the washing water inside the washing tub 1. Includes a dehydration port 3 arranged as an opening structure. A water conducting structure 2 for leading the washing water in the washing tub 1 to a water receiving device 6 under the washing tub 1 is installed corresponding to the dehydration port 3, and the water conducting structure 2 is installed on the tub wall of the washing tub 1. It communicates with the dehydration port 3. In order to expand the capacity of the washing machine, the water in the dehydration stage is discharged from the waterway opening and enters the waterway. In the present invention, the dehydration port 3 of the washing tub 1 is located on the tub wall of the washing tub 1, and a water conducting structure 2 communicating with the dehydration port 3 is installed to effectively utilize the flow of water flow during dehydration of the washing tub 1. It guarantees the function and at the same time reduces the energy consumption.

As shown in FIGS. 1 and 2, in order to expand the volume of the washing tub 1 and further to accommodate more clothes in the washing operation process, the present invention was originally made outside the washing tub 1. Excludes the outer tank that was installed. When the outer tank is eliminated, the water discharged from the waterway enters the drainage tank at the bottom. Due to the demand for capacity expansion, the height of the drainage tank is limited. The water level in the drainage tank has a certain height, and the shape and structure of the water channel directly affect the degree of water scattering during dehydration due to high-speed rotation of the inner tank. Therefore, in the present invention, the water conducting structure 2 is installed on the outer wall of the washing tub 1, and the water conducting structure 2 is installed on the arc-shaped outer wall 201 mainly installed on the portion away from the washing tub 1 and on the portion close to the washing tub 1. The inner wall 202 is included, and the inner wall 202 is on the side closer to the washing tub 1.

The outer wall 201 of the water guide structure 2 is formed into a large arc shape to reduce the area in contact with water during dehydration, ensuring that the washing water can be discharged from the water guide structure 2 more rapidly. In order to prevent the washing water from overflowing from the gap between the dehydration port 3 and the water guide structure 2 during the washing and dehydration work of the washing tub 1, the present invention has a sealed structure between the tub wall of the washing tub 1 and the water conducting structure 2. installed. The sealed structure shown can effectively prevent the washing water from splashing from the gap between the tub wall of the washing tub 1 and the water conducting structure 2.

As shown in FIGS. 1 to 5, the washing tub 1 described in the present invention is arranged as a tub body structure for putting washing water in the washing process. The portion of the wall of the washing tub 1 below the dehydration port 3 is sealed, and the sealed structure guarantees that the washing tub 1 is in a state without holes. In such an installation, the structure of the outer tub is omitted, and the inner tub is mainly used for clothes and washing water. The capacity of the washing tub 1 was increased under the condition that the volume of the entire washing machine did not change or the change was small, and the effect of expanding the capacity of the washing machine was realized. In conventional washing machines, it is necessary to install an outer tub, and by using the outer tub and the inner tub in combination, the corresponding washing and dehydration operations can be performed, so that the outer tub and the inner tub become dirty. May remain, and long-term use is very unhealthy. In the washing tub 1 described in the present invention, water is present only in the washing tub 1 during the washing process. Water exists between the inner and outer tubs of the conventional washing machine, avoids the problem of "hidden dirt" on the outer tub inner wall 202 and the outer wall of the washing tub 1, and has a better washing effect. Further, the outer tub is abolished, and the washing tub 1 is a water receiving tub. There was no water between the inner and outer tubs during the washing process, which reduced the amount of water used for washing and saved the amount of water used for washing.

Further, in the present invention, the water conducting structure 2 is fitted into the outer wall of the washing tub 1. Such an installation extends the service life of the washing tub 1 and is also convenient for maintenance and replacement. Preferably, the outer walls of the water guide structure 2 and the washing tub 1 form a smoothly transitioning curved surface, and when the washing tub 1 rotates at high speed, the smoothly transitioning curved surface can effectively reduce the wind resistance. , Reduces energy consumption and increases washing efficiency.

Further, as shown in FIGS. 4 and 5, in order to guarantee the effect of drainage, the water conducting structure 2 of the present invention includes a first water conducting portion 4 that is closely bonded to the outside of the tub wall of the washing tub 1. The outer wall 201 of the first water conducting portion 4 is combined with the outer wall of the washing tub 1, that is, the inner wall 202 of the first water conducting portion 4, to form a water conducting cavity structure in which the washing water is led out from the washing tub 1. As an advantage of such an installation, when the washing tub 1 is rotating at a high speed during dehydration work of the washing machine, if the number of constituent parts of the washing tub 1 is excessively large, vibration may occur in the process of rotation, and further. Noise is generated and has a certain effect on the user's feeling and sensory organs. The water guide structure 2 and the outer wall of the washing tub 1 are combined to form a water guide cavity, the process of secondary processing is omitted, the service life of the washing tub 1 is extended, and the anti-vibration noise performance of the washing machine is improved.

As shown in FIG. 8, in order to prevent the washing water from overflowing from the gap between the dehydration port 3 and the water conducting structure 2 during the washing and dehydrating work of the washing tub 1, the present invention presents the tub wall and the water conducting of the washing tub 1. A sealed structure 9 was installed between the structures 2. The sealed structure 9 shown can effectively prevent the washing water from scattering from the gap between the tub wall of the washing tub 1 and the water conducting structure 2.

Further, the second water conducting unit 5 includes a second water conducting unit 5 that communicates with the water outlet end of the first water conducting unit 4, and the second water conducting unit 5 guides the washing water to the water receiving device 6 at the lower part of the washing tub 1. Since the washing tub 1 is in a high-speed rotating state during the dehydration operation, the present invention prevents the washing water from flowing back from the water conducting structure 2 into the washing tub 1 while the washing water is in the high-speed rotating washing tub 1. Installes the outer wall 201 of the first water guide portion 4 so as to face from the top to the bottom of the washing tub 1, and the distance from the axis of the washing tub 1 tends to gradually change. Further, the outer wall 201 of the second water guiding portion 5 is installed so as to face from the top to the bottom of the washing tub 1, and the distance from the axis of the washing tub 1 tends to gradually change. More preferably, the distance from the first headrace 4 to the axis of the washing tub 1 tends to increase; the distance from the second headrace 5 to the axis of the washing tub 1 tends to decrease. To do. In the present invention, a water conveyance structure composed of a plurality of parts is installed, and the backflow of the water flow in the drainage process is prevented by utilizing the water flow in the washing tub 1 rotating at high speed, and the water flow is intensively discharged in the drainage process. Guarantee.

A part of the water-conducting structure 2 that goes deep into the washing tub 1 is designed to have a single wall structure. In this way, the water in the water guide structure 2 can be made to enter the larger space in the water receiving device 6 under the washing tub 1 from the water guide cavity as soon as possible, and the amount of water in the water guide structure 2 at the time of dehydration is excessively large. Avoid risks such as increased noise and vibration. This single wall structure leaves the outer part, and water sticks to the outer wall 201 under the action of centrifugal force. The single wall could be blocked, reducing the possibility of scattering from the headrace structure 2. The arcuate shape of the single wall structure coincides with the dehydration direction, reducing shear and stress areas against water, thereby reducing the risk of water splashing. It maximizes the volume of the inner tank and, during dehydration, allows water to stick to the outer wall of the channel under the action of centrifugal force, ensuring that more water can flow out more rapidly and accumulates. In order to reduce the vibration and noise caused by water, the outer wall of the channel exhibits a large arc shape and migrates, and does not migrate with a clear angle.

As shown in FIGS. 1 to 5, the washing tub 1 of the washing machine described in this embodiment includes a washing tub 1 main body arranged as a main body for putting clothes and washing water. A dehydration port 3 is installed at the top of the wall of the washing tub 1, and when the washing machine performs the dehydration work, the washing water in the washing tub 1 is discharged through the dehydration port 3. A water conducting structure 2 for leading the washing water in the washing tub 1 to a water receiving device 6 under the washing tub 1 is installed corresponding to the dehydration port 3, and the water conducting structure 2 is installed on the tub wall of the washing tub 1. It communicates with the dehydration port 3. In order to expand the capacity of the washing machine, the water in the dehydration stage is discharged from the waterway opening and enters the waterway. In the present invention, the dehydration port 3 of the washing tub 1 is located on the tub wall of the washing tub 1, and a water conducting structure 2 communicating with the dehydration port 3 is installed to effectively utilize the flow of water flow during dehydration of the washing tub 1. It guarantees the function and at the same time reduces the energy consumption. The water-conducting structure 2 of the present embodiment forms a water-conducting cavity structure that leads the outer wall of the washing tub 1 and the washing water to the lower part of the washing tub 1. During the dehydration work of the washing machine, the washing water inside the washing tub 1 flows to the dehydration port 3, passes through the water conducting structure 2, is introduced into the water receiving device 6 at the bottom of the washing tub 1, and is discharged by the drainage device.

As shown in FIGS. 1 to 5, this embodiment is a further limitation to the above-mentioned Example 1.

Is hermetically sealed, and the hermetically sealed structure ensures that the washing tub 1 is in a perforated state. In such an installation, the structure of the outer tub is omitted, and the inner tub is mainly used for clothes and washing water. The capacity of the washing tub 1 was increased in a situation where the volume of the entire washing machine did not change or the change was small, and the effect of expanding the capacity of the washing machine was realized. In a conventional washing machine, it is necessary to install an outer tub, and by using the outer tub and the inner tub in combination, the corresponding washing and dehydrating operations can be performed, so that dirt is formed between the outer tub and the inner tub. It may remain and long-term use is very unhealthy. In the washing tub 1 described in the present invention, water is present only in the washing tub 1 during the washing process. Water exists between the inner and outer tubs of the conventional washing machine, avoids the problem of "hidden dirt" on the outer tub inner wall 202 and the outer wall of the washing tub 1, and has a better washing effect. Further, the outer tub is abolished, and the washing tub 1 is a water receiving tub. There was no water between the inner and outer tubs during the washing process, which reduced the amount of water used for washing and saved the amount of water used for washing.

As shown in FIGS. 1 to 5, this embodiment is a further limitation to the above-mentioned Example 1 or Example 2. In this embodiment, except for the outer tub originally located outside the washing tub 1, the volume of the washing tub 1 can be expanded under the condition that the size and volume of the washing machine body do not change or the change is small, and further, washing is performed. More clothing can be accommodated in the process of work. When the outer tank is eliminated, the water discharged from the waterway enters the drainage tank at the bottom. Due to the demand for capacity expansion, the height of the drainage tank is limited. The water level in the drainage tank has a certain height, and the shape and structure of the water channel directly affect the degree of water scattering during dehydration due to high-speed rotation of the inner tank. Therefore, in the present invention, the water conducting structure 2 is installed on the outer wall of the washing tub 1, and the water conducting structure 2 is installed mainly on the arcuate outer wall 201 installed on the portion away from the washing tub 1 and on the portion close to the washing tub 1.
