Description

The present invention belongs to the field of washing machines, and specifically relates to washing machines.

A washing machine is designed as a device that uses electricity to wash clothes. In general, a washing machine rotates a tub for storing washing water, a rotary tub rotatably mounted inside the tub, a pulsator rotatably mounted on the bottom of the rotary tub, and a rotary tub and a pulsator. Includes motors and clutches configured as such. When the rotary tank and the pulsator rotate with the clothes and detergent charged in the rotary tank, the pulsator agitates the washing water together with the clothes charged in the rotary tank, so that dirt is removed from the clothes.

Larger rotary tubs are needed to increase the washing capacity of the washing machine. That is, it is necessary to increase the height or diameter of the rotary tank. Further, when the rotary tank has a larger size, the tank for accommodating the rotary tank and the housing for accommodating the tank also need to be increased with the expansion of the rotary tank. However, the expansion of the housing corresponding to the appearance of the washing machine is greatly restricted by the installation space of the washing machine. In a typical user's house, the location of the washing machine is limited, so it is not very realistic to expand the housing of the washing machine to increase the capacity of the washing tub. Therefore, how to expand the capacity of the washing tub without expanding the housing of the washing machine has become a big challenge for designers.

Patent Document 1 discloses a washing machine having no hole in the inner tub, and refers to the technical field of the washing machine. On the premise of saving water, the washing machine solves the problem that water is scattered when draining from above the inner tub and bacteria easily grow in the outer tub, and it is possible to reduce the cost of the washing machine. It is an invention. A washing machine having no holes in the inner tub includes an inner tub and an outer tub, and a water collecting ring is provided at the tub mouth of the inner tub. The water collecting ring includes a water collecting chamber and a water collecting port and a drainage port communicating with the water collecting room. The water collecting port faces the inside of the inner tank, and the drain port faces the gap between the inner tank and the outer tank. A drainage pipe is connected to the drainage port, and the drainage pipe extends downward to the bottom of the outer tank. According to this structure, a water collecting effect is realized. However, since the eaves of the outer tank are longer than those of the inner tank, the inner tank collides with the outer tank and is easily damaged. Moreover, since the eaves are present, it is difficult to expand the volume of the inner tank. In addition, in the process of dehydrating the inner tank, the water drawn out by high-speed rotation enters the bottom of the outer tank and easily scatters from the outer tank. Further, if the period is long, the housing of the housing is likely to be corroded by the scattered washing water, and a short circuit of the circuit is likely to occur.

In view of the above, the present invention is proposed.

It does not explicitly or imply that it must be configured and manipulated in. Therefore, it should not be understood as limiting the present invention.

In the description of the present invention, the terms "attaching", "connecting", and "connecting" should be broadly interpreted unless otherwise explicitly specified and limited. For example, it may be a fixed connection, a removable connection, or an integrated connection. Further, it may be a mechanical connection or an electrical connection. Further, it may be a direct chain or an indirect chain via an intermediate medium. A person skilled in the art can interpret the specific meanings of the above terms in the present invention according to the specific circumstances.

As shown in FIGS. 1 to 5, in this embodiment, the housing 1, the inner tank 2 installed in the housing 1, the driving device 3 for rotationally driving the inner tank 2, and the bottom of the inner tank 2 Provided is a washing machine including a water collecting device 5 to be installed. At the time of washing / rinsing, the inner tank 2 becomes a water storage tank. The outer wall of the inner tank 2 is provided with a dehydration water channel 4 that communicates with the inner tank 2 and discharges the water drawn from the inner tank 2. The water collecting device 5 includes a water collecting chamber 501 having an upper opening. The bottom wall of the water collecting chamber 501 is provided with a recess 6, and the drain end 401 of the dehydration channel 4 extends downward into the recess 6.

The washing machine of this embodiment is not provided with an outer tub, and the inner tub 2 can be a water storage tub. That is, the dehydration holes are provided only in the upper part, and the inner tank 2 has no holes in the central part and the lower part. A water collecting device 5 is installed at the bottom of the inner tank 2, and when the water is discharged from the inner tank 2, the water discharged from the inner tank 2 can be collected to prevent the water from overflowing. It is said. Further, since the water collecting device 5 does not have an action of restricting the capacity expansion of the inner tank 2, a sufficient space is provided for the capacity expansion of the inner tank 2.

A recess 6 is installed in the bottom wall of the water collecting chamber 501, and the drain end 401 of the dehydration channel 4 is extended to the recess 6 and inserted, which is advantageous for collecting and discharging water. Further, since it is possible to prevent the water discharged during dehydration and drainage from scattering from the water collecting chamber 501, corrosion of the housing 1 due to the scattered water is prevented, and the circuit is short-circuited due to the scattered water. Be prevented. In particular, it is suitable for preventing water scattering when the side wall of the water collecting chamber 501 is low, and an optimum capacity expansion and water scattering prevention effect can be obtained.

The recess 6 may be formed by recessing the bottom wall of the water collecting chamber 501 downward, or an independent member may be separately provided on the bottom wall. For example, a dammed rib 502 is provided on the bottom wall of the water collecting chamber 501, and a recess 6 is formed by the dammed rib 502 and the bottom wall of the water collecting chamber 501.

As a preferred method, the upper end of the side wall of the water collecting chamber 501 is lower than the bottom of the inner tank 2.

Since the upper end of the side wall of the water collecting chamber 501 is lower than the bottom of the inner tank 200, the entire water collecting chamber 501 can be positioned below the bottom of the inner tank 2. As a result, the side wall of the water collecting chamber 501 does not have a structure located between the inner tank 2 and the housing 1, so that even if a certain safety distance is not provided between the inner tank 2 and the water collecting device 5, it is inside. The situation where the tank 2 collides with the water collecting device 5 and is damaged is prevented. Moreover, it is not necessary to provide a safe distance between the water collecting device 5 and the housing 1. Therefore, it is only necessary to design the safe distance between the inner tank 2 and the housing 1, and the diameter of the inner tank 2 can be significantly increased, so that the capacity of the inner tank 2 can be expanded more satisfactorily.

As a preferred method, the water collecting device 5 includes a mounting bottom plate 503 and a dammed rib 502 installed on the mounting bottom plate 503. By surrounding the mounting bottom plate 503 and the dammed rib 502, a water collecting chamber 501 having an upper opening is formed. The upper end of the dammed rib 502 is lower than the bottom of the inner tank 2. Further, the recess 6 is formed by recessing the mounting bottom plate 503 downward.

A water collecting chamber 501 is formed by providing a mounting bottom plate 503 and a dammed rib 502 and surrounding them. The mounting bottom plate 503 and the dammed rib 502 may be integrally molded or may be fixed in a sealed shape. The recess 6 may be formed by providing the recess 6 directly on the mounting bottom plate 503 and recessing it. The structure is simple and easy to process and mold.

As a further measure, when the horizontal projection of the inner tank 2 is located inside the horizontal projection of the water collection chamber 501, the drain end 401 of the dehydration channel 4 extends or bends vertically downward. It may be stretched and inserted into the recess 6, but it is preferably stretched vertically downward. In this case, since it is not necessary to calculate the bending angle, machining becomes easy. Moreover, since the water flow is not obstructed by bending, it becomes smoother and more advantageous for drainage.

When the horizontal projection of the inner tank 2 covers the horizontal projection of the water collecting chamber 501, the drain end 401 of the dehydration channel 4 bends inward and extends to the recess 6. In such a plan, the outer diameter of the water collecting chamber 501 is smaller than the outer diameter of the inner tank 2, whereas the dehydration channel 4 is installed on the outer peripheral wall of the inner tank 2, so that it bends inward. It is necessary to enter. The dehydration channel 4 may be bent a plurality of times and inserted into the recess 6.

The recess 6 may communicate with the drain pipe 8 of the washing machine via the pipe line 11 and quickly and directly discharge the water in the recess 6 from the drain pipe 8 to prevent the water from scattering from the upper part. .. Further, the bottom wall of the water collecting chamber 501 may be fully utilized, and the drain port 7 may be provided at the bottom of the water collecting chamber 501. In this case, the bottom wall of a part of the water collecting chamber 501 is made lower than the bottom of the recess 6. The water in the recess 6 is collected directly in the water collecting chamber 501 and then can be discharged from the drain port 7. With this method, it is not necessary to separately install the pipeline 11.

As shown in FIGS. 1 to 3, the first embodiment is further limited in this embodiment. The recess 6 of this embodiment is formed by recessing the bottom wall of the water collecting chamber 501 downward. The recess 6 is an annular recess 601 formed by recessing the bottom wall of the water collecting chamber 501 downward along the circumferential direction. The drainage end 401 of the dehydration channel 4 extends downward into the opening of the annular recess 601.

In the water collecting chamber 501, an annular groove 601 is formed by recessing the bottom wall downward in the manufacturing process, so that the manufacturing is simple and convenient, and the cost is low. Alternatively, an annular dammed rib is provided on the inner bottom wall of the water collecting chamber 501, and the dammed rib is surrounded by the bottom wall and the side wall of the water collecting chamber 501 to form an annular concave groove 601. Alternatively, an annular groove 601 is formed by surrounding the water collection chamber 501 with a plurality of annular dammed ribs. Regardless of the method, it is sufficient that the recess 6 can be formed and the water can be prevented from scattering in cooperation with the drainage end 401 of the dehydration channel 4.

The drainage end 401 of the dehydration channel 4 is inserted into the annular recess 601. When the inner tank 2 is rotated, the drain end 401 of the dehydration channel 4 rotates in the annular recess 601 so that it does not get in the way. The annular recess 601 is lower than the bottom wall of the water collection chamber 501, and the drainage end 401 extends downward into the opening of the annular recess 601. In this way, the water discharged into the dehydration channel 4 directly enters the annular recessed groove 601. However, since the space of the recessed groove 601 is relatively small, the water does not scatter from above the water collecting chamber 501.

Preferably, the outer wall of the drainage end 401 of the dehydration channel 4 and the inner wall of the annular recess 601 are close to each other and are separated by a certain gap. As a result, the dehydration water channel 4 can rotate smoothly without colliding with the inner tank 2, and the gap can be made as small as possible, so that water scattering from the upper part can be avoided.

As a further measure, the annular recess 601 is located below the dehydration channel 4. The drainage end 401 of the dehydration channel 4 extends vertically downward and is inserted into the annular recess 601.

The positions of the drainage end 401 of the dehydration channel 4 and the annular recess 601 need to be installed so as to be combined with each other. By installing the annular concave groove 601 coaxially with the inner tank 2 and making the diameter closer to the inner tank 2, the upper opening of the annular concave groove 601 can just face the drainage end 401 at the lower part of the dehydration channel 4. Become. Since the drainage end 401 of the dehydration channel 4 is inserted vertically into the annular recessed groove 601, processing is easy. Moreover, since the water flow is not obstructed by bending, it becomes smoother, which is more advantageous for drainage.

As a preferred method, the edge of the drainage end 401 of the dehydration channel 4 is provided so as to be inclined. By lowering the outside of the edge of the drainage end 401 and raising the inside, it is possible to direct the flow direction of the water flow inward during the rotation process. As a result, the scattering of water from the water collecting chamber 501 is avoided.

As a further measure, a horizontal retaining rib is provided in the opening of the annular recessed groove 601. The horizontal retaining rib extends from the edge of the opening toward the center of the opening, and prevents water from scattering at a certain distance from the outer wall of the drain end 401 of the dehydration channel 4.

A horizontal retaining rib is provided in the opening of the annular groove 601. After the drain end 401 of the dehydration channel 4 is inserted into the annular recess 601 the horizontal retaining rib acts as a lid by blocking the annular recess 601. This makes it possible to avoid the water in the groove from scattering from the upper part. Moreover, since the horizontal retaining rib separates a certain gap from the outer wall of the drainage end 401, the rotation of the dehydration water channel 4 accompanying the inner tank 2 is not hindered.

As a further alternative, the washing machine includes a drain pipe 8. The annular concave groove 601 communicates with the drain pipe 8 via the pipe line 11, and the water in the annular concave groove 601 is directly discharged to the drain pipe 8.

Since the bottom of the annular recess 601 in the present plan is lower than the bottom wall of the water collection chamber 501, it is impossible to directly discharge water from the bottom of the annular recess 601 to the water collection chamber 501. .. Therefore, by providing the pipeline 11 and directly communicating the annular concave groove 601 with the drain pipe 8, the water in the annular concave groove 601 can be discharged. As a result, the water does not become excessive and overflow from the upper part of the annular concave groove 601, and the scattering of water is avoided.

Preferably, the height of one end of the conduit 11 near the annular groove 601 is made higher than the height of one end near the drainage pipe 8. This makes it easier for the water in the water collecting chamber 501 to smoothly flow into the drain pipe 8.

As a further measure, the drain pipe 8 of the washing machine is located inside the inner circumference of the annular recessed groove 601 and is connected to the bottom wall of the water collecting chamber 501. One end of the annular groove 601 is close to the drain pipe 8 and the other end is separated from the drain pipe 8. The height of the bottom wall of the annular groove 601 is provided so as to incline downward from the outside to the inside in the radial direction. And / or, the height of the bottom wall of the annular recess 601 at one end close to the drain pipe 8 is lower than the height of the bottom wall of the annular recess 601 at one end away from the drain pipe 8.

Preferably, the annular groove 601 has a pipe line 11 connected to the bottom wall at the lowest height, and communicates with the drain pipe 8 via the pipe line 11.

Since the bottom wall of the annular groove 601 is provided so as to be inclined, the water flow can be guided from the high side to the low side. As a result, the speed of the water flow is accelerated and the puddle can be avoided. Further, since the pipe line 11 is provided on the side closer to the drainage pipe 8 and the annular recessed groove 601 communicates with the drainage pipe 8 to drain the water, the distance of the pipe line 11 is shortened and the installation is easy. Therefore, the height of the bottom wall of the annular recessed groove 601 in the present plan becomes lower toward the side where the drain pipe 8 exists in each direction.

Usually, the annular concave groove 601 is provided on the outer periphery of the bottom wall of the water collecting chamber 501, and the drain pipe 8 is provided corresponding to the inside of the inner circumference of the annular concave groove 601. In this case, if the height of the bottom wall is provided so as to incline downward from the outside to the inside in the radial direction, the water flow tends to gather in the center. Further, by raising one end of the annular recessed groove 601 that is close to the drain pipe 8 in the horizontal direction and lowering one end that is separated from the drain pipe 8, the water flow tends to collect at one end on the lower side. This makes it easier for water to be discharged to the drain pipe 8 through the pipeline 11.

As shown in FIG. 4, the present embodiment further limits the first embodiment and is another embodiment relating to the recess 6. In this embodiment, the recess 6 is formed by gradually lowering the height of the bottom wall of the water collecting chamber 501 from all sides toward the center. Further, the drainage end 401 of the dehydration channel 4 extends into the recess 6.

The bottom wall of the water collecting chamber 501 of this embodiment is provided so as to incline downward from the outside to the inside. Therefore, the formed recess 6 resembles a funnel type and can accelerate the speed of water flow. When the drainage end 401 of the dehydration channel 4 is extended to the recess 6, the discharged water can rapidly flow to the lowest point of the water collection chamber 501 without collecting at a high position. Therefore, it is safer because water does not scatter from the water collecting chamber 501 or the housing 1 during rotation and dehydration.

Preferably, a drain port 7 is provided in the center of the bottom wall of the water collecting chamber 501, and the drain port 7 communicates with the drain pipe 8 of the washing machine. When the water in the recess 6 collects in the center of the water collecting chamber 501, it is discharged from the drain port 7.

The center of the water collection chamber 501 is the lowest part of the bottom wall, and all the water discharged from the dehydration channel 4 is concentrated here. Therefore, by providing the drainage port 7 in the center of the bottom wall, the collected water can be discharged to the maximum extent possible, and the accumulation of dirt and bacteria can be avoided. Further, unlike the case where the pipeline 11 is installed, it is easy and convenient.

As shown in FIG. 5, the present embodiment further limits the first embodiment and is another embodiment relating to the recess 6. In this embodiment, the height of the bottom wall of the water collecting chamber 501 of the water collecting device 5 is lowered stepwise from the outer circumference toward the center to form the stepped recess 6. The drainage end 401 of the dehydration channel 4 extends downward and is inserted into the stepped recess 6.

The stepped recess 6 is installed in combination with the drainage end 401 of the dehydration channel 4. As a result, the drainage end 401 of the dehydration channel 4 is inserted by extending exactly to the stepped recess 6, so that the discharged water can rapidly flow out through the downstairs. In addition, the step at the top prevents water from splashing from the top. Moreover, the rotation of the dehydration water channel 4 accompanying the inner tank 2 is not hindered.

Preferably, the stepped recess 6 includes a vertical bend 9 and a horizontal bend 10. The drainage end 401 of the dehydration channel 4 is just opposed to the horizontal bent portion 10, and the side wall of the drainage end 401 is close to the vertical bent portion 9.

The stepped recess 6 may include one vertical bending portion 9 and one horizontal bending portion 10 connected to the bottom portion, or may include a plurality of vertically bending portions 9 and a plurality of horizontal bending portions 10 to be connected. The side wall of the drainage end 401 is close to the vertical bending portion 9 and can prevent the water flow from scattering upward. Further, since the drainage end 401 of the dehydration water channel 4 just faces the horizontal bending portion 10, the water flow quickly flows downward without collecting water, so that the water flow is further prevented from scattering to the outside.

Preferably, the lower edge of the stepped recess 6 is inclined downward from the outside to the inside and extends to the center to form an inclined plane. Further, a drainage port 7 is provided in the center of the bottom wall of the water collecting chamber 501. The water in the recess 6 is collected by the inclined flat surface, enters the drain port 7, and is discharged.

As shown in FIG. 5, the stepped recess 6 includes a vertical bend 9 and a horizontal bend 10 corresponding to the drainage end 401 of the dehydration channel 4. The inner edge of the horizontal bent portion 10 extends to the center while inclining downward from the outside to the inside. At this time, since the bottom wall of the water collecting chamber 501 connected to the stepped recess 6 resembles a funnel shape, the speed of the water flow is accelerated. As a result, the discharged water can rapidly flow to the lowest point of the water collecting chamber 501 without collecting at a high position. Therefore, it is safer because water does not scatter from the water collecting chamber 501 or the housing 1 during rotation and dehydration. Further, by providing the drainage port 7 in the center of the bottom wall, the collected water can be discharged to the maximum extent, and the accumulation of dirt and bacteria can be avoided. Moreover, unlike the case where the pipeline 11 is installed, it is easy and convenient.
