Description

The present invention relates to a technical field of a washing machine, and more specifically to a washing machine.

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 disturbs 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, it is necessary to increase the storage tank and the housing for accommodating the rotary tank as the rotary tank expands.

However, the expansion of the housing corresponding to the appearance of the washing machine is regulated by the space of the washing machine installation area. In a typical user's home, the location of the washing machine is limited, so it is not very realistic to achieve the purpose of expanding the housing of the washing machine to increase the capacity of the washing tub. Therefore, how to increase the capacity of the rotary tub without expanding the housing of the washing machine has become a big challenge for designers.

The washing machine of the present invention will be described in detail below by combining the drawings.

As shown in FIGS. 1 to 6, the washing machine of this embodiment includes a washing tank 200 that can be used for storing water in the washing process, and a water collecting device 500 for collecting wastewater from the washing tank. The water collecting device 500 includes a water collecting chamber 503.

The washing tub 200 of the washing machine in this embodiment is a water storage tub, and an outer tub is not installed outside the washing tub 200. Further, in this embodiment, the water collecting device 500 is installed only at the bottom of the cleaning tank 200. As a result, the washing water in the washing tank is discharged to the water collecting device 500 and then discharged. Therefore, the water collecting device 500 has a water collecting chamber 503 to realize a primary water storage function.

Since the washing tub of the washing machine in this embodiment is a water storage tub, a "holeless washing tub" design is adopted for the washing tub. Further, by omitting the outer tank, the water collecting device is changed to collect and discharge only the wastewater from the washing tank. As a result, the washing machine of this embodiment has the following technical effects.

1. 1. Since the capacity of the washing tub can be increased without changing the volume of the housing, the effect of increasing the capacity of the washing machine is realized.

2. In the washing process, since water exists only in the washing tub, water collects between the inner tub and the outer tub like a conventional washing machine, and "dirt and dirt" on the inner wall of the outer tub and the outer wall of the washing tub. The problem of "adhering" is avoided. Therefore, it has a better cleaning effect.

3. 3. By omitting the outer tank and using the washing tank as a water storage tank, there is no accumulated water between the inner tank and the outer tank in the washing process. As a result, the amount of washing water is reduced, so that the amount of washing water can be saved.

By increasing the capacity of the washing machine, the water in the dehydration stage is discharged from the water channel opening of the washing tub. In addition, since there is no outer tank, the water discharged from the water channel enters the water collecting chamber of the water collecting device. However, due to the need to increase the capacity, the height of the water collecting device is limited, and the water level in the water collecting chamber has a constant height. Further, when the washing tank rotates at high speed to dehydrate, the water level rises and the water flow comes into close contact with the inner wall of the water collecting chamber. Therefore, if the water is not discharged promptly, the water will overflow from the drainage ditch due to the scattering of water and the rise of the water level. Therefore, in this embodiment, the problems of water scattering and overflow from the water collecting device are solved by increasing the volume of the water collecting chamber as much as possible without changing the height of the water collecting device.

Therefore, the water collecting chamber 503 of this embodiment is provided with a capacity increasing structure for increasing the volume. The capacity-increasing structure realizes the purpose of increasing the volume by expanding the water collecting chamber 503 to the outside as much as possible without changing the height of the water collecting device. This avoids the problem of water splashing and overflowing from the water collector.

Further, the bottom wall of the water collecting chamber 503 of the present embodiment includes a bottom wall main body 505 located at the center and a water collecting tank 502 located on the outer periphery of the bottom wall main body 505 and recessed downward. Further, the water collecting device 500 includes a drain port 504 communicating with the water collecting tank. The capacity-increasing structure is located on the side wall of the water collecting tank 502 near the bottom wall main body 505, and is used to increase the volume of the water collecting tank 502.

In this embodiment, the depth of the water collecting chamber is partially increased by the water collecting tank 502, and the outlet end of the drainage path of the washing tank is extended into the water collecting tank 502 of the water collecting device 500. As a result, even if the washing tank is dehydrated by high-speed rotation, the discharged water directly enters the deeper water collecting tank 502, so that water scattering and overflow can be avoided.

As is clear from the above, the wastewater from the washing tank is discharged directly into the water collecting tank 502 of the water collecting device. Therefore, in the present invention, if the capacity increasing structure is provided in the water collecting tank 502 to increase the volume of the water collecting tank 502, it is possible to avoid water scattering and overflow. In this case, the height and strength of the water collecting device are guaranteed because it is not necessary to deepen the whole.

As one embodiment of the present embodiment, the capacity increase structure includes a first capacity increase unit 512. The first capacity increasing portion 512 is formed by extending the side wall of the water collecting tank 502 near the bottom wall main body while inclining toward the bottom wall main body. As a result, the volume of the water collecting tank 502 increases.

The installation method and inclination angle of the first capacity increasing portion 512 in this embodiment must all guarantee the height and strength of the entire water collecting device. Specifically, the side wall of the water collecting tank 502 near the bottom wall main body 505 is extended while being inclined toward the bottom wall main body 505 in the entire circumferential direction to form the first capacity increasing portion 512 over the entire circumference. Alternatively, the side wall of the water collecting tank 502 near the bottom wall main body 505 is extended while being partially inclined toward the bottom wall main body 505 to increase a plurality of first capacities distributed along the outer periphery of the bottom wall main body. Part 512 is formed.

In the first capacitance increasing portion of the present embodiment, the inclination angle of each position in the entire circumferential direction of the bottom wall main body is the same. By doing so, the volume of the water collecting tank 502 can be increased as much as possible.

Alternatively, in the first capacitance increasing portion, the inclination angle of each position in the entire circumferential direction of the bottom wall main body is gradually increased. By doing so, a transition structure is formed between the side wall of the water collecting tank and the bottom wall main body 505, and a certain water guiding action is provided, so that water is guided into the water collecting tank 502 by the bottom wall main body.

As one embodiment of the present embodiment, the capacity increasing unit includes a second capacity increasing unit 513. The second capacity increasing portion 513 is formed by recessing the side wall of the water collecting tank 502 near the bottom wall main body 505 toward the bottom wall main body 505.

Further, the second capacity increasing portion 513 is formed by denting a part of the side wall near the bottom wall main body in the water collecting tank toward the bottom wall main body, and is distributed on the outer periphery of the bottom wall main body. including. Of these, at least one inner recess is provided corresponding to the position of the drainage port.

Further, the inner recessed portion corresponding to the drainage port is larger than the other inner recessed portions.

Further, a dehydration hole is provided in a portion of the tank wall of the cleaning tank 200 located above the maximum water level, and the cleaning tank 200 can be drained from the dehydration hole in the dehydration process. Further, a dehydration drainage device 300 is provided on the outer wall of the washing tank 200. The water inlet end of the dehydration drainage device 300 communicates with the dehydration hole, and the water discharge end of the dehydration drainage device 300 extends into the water collection chamber 503 of the water collector 500.

Since the washing tub 200 of the washing machine in this embodiment is a "washing tub without holes", the washing tub 200 becomes a water storage tub during the washing process. Further, since the dehydration hole is provided in the portion of the tank wall of the cleaning tank 200 above the maximum water level, the dehydration function is realized. Moreover, a dehydration drainage device is provided on the tank wall of the washing tank 200. As a result, the water in the dehydration process of the washing machine is guided into the water collecting chamber 503 of the water collecting device 500 through the dehydrating drainage device, collected and discharged, so that the dehydrated water flow is scattered in the housing of the washing machine. Is prevented.

Further, the dehydration drainage device 300 includes a drainage path extending from top to bottom into the water collection tank 502 of the water collection device 500. The vertical depth of the water collecting tank 502 gradually increases along the rotation direction of the washing tank during dehydration. In this embodiment, since the dehydration drainage device 300 is extended into the water collection tank 502 of the water collection device 500, it is possible to collect and discharge the water in the dehydration process into the water collection tank 502. Moreover, since the depth of the water collecting tank 502 is larger than that of the water collecting chamber 503, it is possible to prevent the drainage from scattering during dehydration.

Further, a plurality of dehydration holes are provided at the tank mouth position of the washing tank 200 of this embodiment. In addition, there are a plurality of drainage routes, and each dehydration hole has a one-to-one correspondence. The upper end of the drainage path communicates with the dehydration hole, and the lower end extends into the water collecting tank 502 of the water collecting device.

The spout ends of the multiple drainage channels all communicate with the inside of the annular water collection tank.

Further, the drain port 504 in this embodiment is provided at the lowest water level in the annular water collecting tank 502. The drain port 504 extends toward the bottom wall main body 505 so as to satisfy the demand for the amount of drainage. As a result, the diameter of the drainage port 504 can be expanded, so that the discharge water flow rate is increased and the drainage requirement is satisfied, and as a result, the accumulated water and the overflow in the water collecting device 500 are avoided.
