Description

Technical Field

[0001] The invention belongs to the technical field of washing equipment, and in particular relates to a washing machine. Background Art

[0002] Traditional fully automatic pulsator washing machines generally include an inner barrel, an outer barrel, a vibration reduction component and a power system. When washing and dehydrating, the inner barrel rotates relative to the outer barrel, so that the clothes react with the washing water to achieve the purpose of washing or dehydrating. Among them, the outer barrel is installed outside the inner barrel to provide support for the inner barrel. The outer barrel serves as a water storage barrel, and the side wall of the inner barrel is evenly distributed with drainage holes to connect the inner and outer barrels. During the washing process, the clothes are placed in the inner barrel, and the water levels of the two barrels are the same, but the outer barrel does not contact the clothes. The outer barrel of the existing washing machine is larger than the inner barrel, resulting in a large amount of washing water between the inner and outer barrels. The washing liquid between the two barrels cannot be fully utilized, which not only increases the amount of water used for washing, but also reduces the concentration of the washing liquid during washing, and also causes the overall volume of the washing machine to be larger. In addition, after a period of use, dirt will adhere to the inner wall of the outer barrel and the outer wall of the inner barrel, and even mold will grow, which will then contaminate the washed clothes, and the barrel wall is difficult to clean.

[0003] In response to this situation, some manufacturers have made improvements. In order to save water resources, more and more washing machines use a hole-free inner barrel, which separates the inner and outer barrels, and only stores water in the inner barrel, while the outer barrel is empty. A drainage hole is opened at the upper end of the inner barrel side wall. In this way, when the washing machine is dehydrating, the water is thrown onto the inner wall of the inner barrel due to the centrifugal force, and moves upward along the inner wall of the inner barrel and is discharged from the drainage hole at the upper end of the inner barrel, which improves the water-saving effect of the washing machine and saves the amount of detergent.

[0004] However, the above scheme has the following problems: since the washing machine rotates at high speed during dehydration, water in the clothes is thrown out through the drainage holes on the side wall of the inner tub and directly hits the side wall of the outer tub, which is easy to splash everywhere. If there is water on the inner wall of the outer tub for a long time, it is easy to breed bacteria, which is not conducive to environmental protection.

[0005] In addition, in order to increase the washing capacity of the washing machine, a larger inner barrel is required, that is, the height or diameter of the inner barrel needs to be increased. If the inner barrel has a larger size, the outer barrel and the housing that accommodate the inner barrel also need to be increased as the inner barrel increases.

[0006] The increase in the size of the washing machine casing is limited by the space in the area where the washing machine is installed. The space for placing a washing machine in an average user's home is limited, and it is not realistic to increase the capacity of the washing tub by adding a washing machine casing. How to increase the capacity of the inner tub without increasing the casing of the washing machine has become a major problem that has troubled designers.

[0007] Chinese patent application number CN99230455.5 discloses a single-barrel water-saving washing machine, in which a water collecting device is provided at the mouth of the washing barrel, and the water collecting port of the water collecting device is surrounded by the washing barrel at the mouth of the washing barrel. The water collecting cavity of the water collecting device at the mouth of the barrel is connected to a plurality of drainage pipes, which are symmetrically arranged from top to bottom along the outer wall of the washing barrel. When drying, the water collecting device collects the centrifugal water flow due to high-speed rotation and guides it downward for drainage. Although this structure omits the outer barrel, when the washing machine is dehydrated, since the washing water first enters the water collecting device, the water collecting device is a ring-shaped structure, and the washing water filled inside drains downward at different speeds, which destroys the balance of the high-speed rotation of the washing barrel; in addition, the washing water is guided to the washing machine after entering the water collecting device. The lower part of the barrel is collected and discharged toward the center, which is not conducive to drainage. Under the action of centrifugal force, the washing water is concentrated in the water collecting chamber and is difficult to discharge, causing the washing water to be concentrated at the upper end of the washing barrel, increasing the weight of the upper part of the washing barrel, and further destroying the balance. In particular, when there is a lot of residual water in the washing barrel, most of the washing water is concentrated in the water collecting chamber and is not discharged, which increases the overall center of gravity of the washing barrel and the outer barrel, generating great vibration and noise, and also increases the working load of the dehydration motor, which is easy to damage the motor; finally, the water collecting device is arranged on the upper part of the washing barrel, and when the washing barrel is dehydrated and rotated, the radial displacement of the upper eccentric is the largest. In order to avoid the water collecting device colliding with the washing machine case, the safety distance between the water collecting device and the case must be met, and the purpose of capacity expansion cannot be truly achieved.

[0008] In view of this, the present invention is proposed. Summary of the invention

[0034] The washing tub of the washing machine of the present invention can be used to hold water during the washing process, so the washing tub adopts a "holeless inner tub" structure, while the design of the outer tub is eliminated, and a water receiving device is used instead of the outer tub to receive and drain water, which makes the present invention have the following technical effects:

[0035] 1. The capacity of the washing tub can be increased while the volume of the washing machine remains unchanged, thus achieving the effect of expanding the capacity of the washing machine;

[0036] 2.

[0038] 4. The water is discharged from the first drain port at the lower part of the washing tub wall by using the water guide channel from top to bottom inside the washing tub, which can avoid the water guide structure installed on the upper part of the outer wall of the washing tub in the prior art occupying the space between the washing tub and the box body, thereby achieving a real capacity expansion effect;

[0039] 5. The water inlet of the water guide channel is set on the radial side wall consistent with the dehydration rotation direction of the washing tub, and the reverse radial side wall is sealed. During dehydration, the washing water is easier to enter the water guide channel along the circumference of the washing tub, thereby improving the drainage rate;

[0040] 6. A drainage channel is installed at the lower part of the outer wall of the washing tub to guide the water out of the first drainage port downward, which can not only prevent the water receiving device from extending upward to achieve the expansion effect, but also guide the drainage to the water collecting chamber of the water receiving device to increase the drainage speed and obtain the effect of preventing splashing;

[0041] 7. The bottom wall of the water collecting chamber of the water receiving device is provided with an annular groove structure for guiding water to the drain outlet, so as to better guide and drain water and ensure that water splashes out of the drainage channel while better collecting and draining water to prevent water accumulation and overflow.

[0066] Furthermore, there are at least two first drainage ports 201 disposed at intervals along the circumference of the washing tub 200 , and there are at least two drainage channels 300 disposed at intervals along the circumference of the washing tub 200 .

[0067] Embodiment 2

[0068] like Figure 4 As shown, the drainage channel 300 of this embodiment is an independent structure, including a shell 303, a water inlet 301 provided at one end of the shell 303 and a water outlet 302 provided at the other end of the shell. The water inlet 301 is connected to the first drainage port 201. The shell 303 has a drainage chamber 304 from the water inlet 301 to the water outlet 302 (see Figure 2 , 3 ).

[0069] Preferably, the water inlet 301 is disposed on a side wall 3031 of the housing 303 adjacent to the outer peripheral wall of the washing tub 200 , and seals and covers the first drain port 201 of the washing tub.

[0070] Further preferably, the water outlet is arranged on the side wall of the housing away from the outer peripheral wall of the washing tub (not shown in the figure), or the water outlet 302 is arranged to discharge water downward (see Figure 2 , 3 ).

[0071] Embodiment 3

[0072] The difference between this embodiment and the above embodiment is that Figure 2 and Figure 3 As shown, the drainage channel 300 and the outer wall of the washing tub 200 cooperate to form a drainage chamber 304. The drainage channel 300 includes a cover body 305, which is arranged on the outer peripheral wall of the washing tub 200 and cooperates with the outer peripheral wall of the washing tub 200 to form a chamber 304 for downward drainage. The first drain port 201 constitutes a water inlet 301 of the chamber, and the lower part of the chamber 304 has a water outlet 302.

[0073] Furthermore, the water outlet is arranged on the cover body, or the downward opening between the cover body and the outer peripheral wall of the washing tub constitutes the water outlet (not shown in the figure).

[0074] Embodiment 4

[0075] like Figure 1 and Figure 5 As shown, a washing machine of the present embodiment includes a washing tub 200 that can be used to hold water during the washing process and a water receiving device 500 for collecting water discharged from the washing tub 200, the water receiving device 500 includes a water collecting chamber 501 and a second drain port 502 communicated with the water collecting chamber 501, and a water outlet 302 for downward drainage of the drainage channel 300 is located in the water collecting chamber 501.

[0076] Preferably, the upper edge of the peripheral wall 503 constituting the water collecting chamber is higher than the height of the water outlet 302 of the drainage channel 300 .

[0077] More preferably, the upper edge of the peripheral wall 503 of the water collecting chamber is not higher than the height of the first drain port 201 .

[0078] In this embodiment, the washing tub peripheral wall above the first drain port 201 is a sealing structure, and the interior of the washing tub 200 is connected to the outside through the first drain port 201 at the lower part of the peripheral wall, that is, the washing tub peripheral wall except the first drain port 201 is a sealing structure.

[0079] The washing tub 200 serves as the water storage tub of the washing machine. An outer tub is no longer provided outside the washing tub 200, and only a water receiving device 500 is provided at the bottom of the washing tub 200. In this way, the washing water of the washing tub is discharged into the water receiving device 500 and then discharged from the second drain port 502. Therefore, the water collecting chamber 501 of the water receiving device 500 has the function of receiving and collecting water. The height of the water receiving device 500 is less than the height of the washing tub 200. The bottom of the washing tub 200 is located in the water collecting chamber 501, and at least the upper part of the washing tub extends out of the upper opening of the water collecting chamber 501.

[0080] Embodiment 5

[0081] The washing tub 200 of the washing machine of the present embodiment is a "holeless inner tub". The washing tub 200 is a water storage tub during the washing process. A first drain port 201 is provided at the lower part of the barrel wall of the washing tub 200 to realize the dehydration function. At the same time, a drainage channel is provided on the barrel wall of the washing tub 200 to guide the water in the dehydration process of the washing machine to the water collecting chamber 501 of the water receiving device 500 through the drainage channel for collection and discharge, thereby preventing the dehydrated water from splashing into the washing machine body.

[0082] The bottom wall of the water collecting chamber 501 of this embodiment is provided with a water guiding structure for guiding water flow to the second drain port 502, which can ensure that the water flow is discharged in time and prevent the water receiving device 500 from overflowing due to excessive water accumulation too quickly. The entire bottom wall or part of the bottom wall of the water collecting chamber 501 is set in a transition from high to low to form the water guiding structure, and the second drain port 502 is set at a position below the highest water level on the bottom wall of the water collecting chamber 501. In this way, the drainage can be better discharged to the second drain port 502 along the water guiding structure of the water collecting chamber 501.

[0083] Embodiment 6

[0084] The bottom wall of the water collecting chamber 501 described in this embodiment is provided with a concave annular groove 504, and the annular groove 504 extends downward below the height of the bottom wall of the water collecting chamber 501. The depth of the annular groove 504 in the vertical direction is set in a transition from high to low to form the water guiding structure. The second drain port 502 is set in the annular groove 504 and is located at the lowest position. The water outlet 302 of the drainage channel 300 is set in the annular groove. In this embodiment, a concave annular groove 504 is set in the water collecting chamber 501, which can increase the volume of collected water on the one hand, and prevent water from splashing out on the other hand. Since the water level of the annular groove in the water collecting chamber 501 is the lowest, it is more conducive to drainage to set the second drain port 502 in the annular groove.

[0085] Specifically, the annular groove 504 described in this embodiment is circumferentially arranged along the bottom wall of the water collecting chamber 501, and the depth of the annular groove 504 in the vertical direction transitions from high to low in a clockwise or counterclockwise direction to form the water guiding structure.

[0086] Preferably, the depth of the annular groove 504 is set to change from high to low along the same direction as the washing tub 200 turns when dehydrating.

[0087] As a preferred implementation of this embodiment, the bottom of the annular groove 504 is a spiral structure or a step structure from high to low, and the second drain port 502 is arranged in the annular groove and is located at the lowest water level position of the spiral structure or the step structure. In this way, the drainage can be completely drained to avoid water retention in the water collection chamber 501.

[0088] Embodiment 7

[0089] The water receiving device 500 of this embodiment is located below the washing tub 200 and is arranged coaxially with the washing tub. The drainage channel 300 includes a partial structure extending from top to bottom into the annular groove 504 of the water receiving device 500; the depth of the annular groove 504 in the vertical direction gradually increases along the direction of rotation of the washing tub during dehydration. In this embodiment, the drainage channel 300 is extended into the annular groove 504 of the water receiving device 500, and the water in the dehydration process can be collected in the annular groove 504 and discharged. At the same time, the depth of the annular groove 504 is greater than the water collecting chamber 501, which can prevent the dehydration and drainage from splashing.

[0090] The water receiving device 500 of this embodiment is a basin-shaped structure with a cavity inside. The water receiving device 500 is suspended in the washing machine housing 100 through a suspension rod 700. A suspension rod mounting seat 505 for mounting the suspension rod 700 is provided on the outer peripheral wall of the water receiving device 500. Preferably, the suspension rod mounting seat includes four, which are evenly distributed along the circumference.

[0091] A driving device 600 is installed on the bottom wall of the water receiving device 500 of this embodiment. The driving device has a washing tub shaft and a pulsator shaft for driving the washing tub 200 and the pulsator 800 to rotate.

[0092] Embodiment 8

[0093] like Figure 1 and Figure 3 As shown, the inner wall of the washing tub 200 of the washing machine of the present invention is also provided with a water guide channel 400 for guiding water to be discharged from top to bottom, the lower part of the water guide channel 400 covers the first drain port 201, the upper part is provided with a water inlet 401 and defines a water guide chamber 402 connected with the water inlet 401 and the first drain port 201, and the water guide chamber 402 is connected with the interior of the washing tub 200 through the water inlet 401.

[0094] Furthermore, the water guide channel 400, the first drain port 201, and the drain channel 300 are sequentially connected to form a passage for draining water from the inside to the outside of the washing tub 200.

[0095] In this embodiment, there is at least one first drain port 201 , and there is at least one water guiding channel 400 . The lower part of each water guiding channel 400 is covered with at least one corresponding first drain port 201 .

[0096] Preferably, there are at least two first drain ports 201 disposed at intervals along the circumference of the washing tub 200 , and there are at least two water guide channels 400 disposed at intervals along the circumference of the washing tub 200 .

[0097] Furthermore, the water guide channel 400 is an independent structure, and a water guide chamber is provided in the water guide channel 400, or the water guide channel 400 and the inner peripheral wall of the washing tub 200 cooperate to form a water guide chamber (see Figure 7 and Figure 8 ), the installation structure of the water guide channel and the washing tub can refer to the design of the drainage channel.

[0098] like Figure 7 and Figure 8 As shown, the water inlet 401 is arranged on the radial side wall 403 of the water guide channel 400, preferably, it is arranged on the radial side wall consistent with the dehydration rotation direction of the washing tub 200, and the opening direction of the water inlet 401 is consistent with the dehydration rotation direction of the washing tub.

[0099] Preferably, a balance ring 900 is provided on the opening of the washing tub 200 of this embodiment, and a gap is provided between the radial side wall 403 of the water guide channel 400 and the washing tub 200 in the same direction of dehydration rotation and the balance ring 900, forming the water inlet 401 (see Figure 7 ), the reverse radial side wall 404 extends to the lower surface of the balance ring 900, and is preferably sealed with the lower surface of the balance ring 900.

[0100] Embodiment 9

[0101] Such as 1. Figures 9 to 15As shown, the washing tub 200 of the washing machine of this embodiment is used as a water storage tub, and no outer tub is set outside the washing tub 200. In this embodiment, only a water receiving device 500 is set at the bottom of the washing tub 200. In this way, the washing water of the washing tub is discharged to the water receiving device 500 and then discharged. Therefore, the water receiving device 500 has a water collecting chamber 501 to realize the function of temporarily storing water. Although the washing machine of this embodiment no longer has an outer tub, the bottom of the washing tub 200 is still set in the water collecting chamber of the water receiving device 500. Therefore, the washing tub 200 needs to be relatively fixed with the water collecting chamber of the water receiving device to prevent the washing tub from colliding with the water receiving device when dehydrating. In this embodiment, a reinforcing structure for increasing the strength of the water collecting chamber 501 is set on the peripheral wall 503 of the water collecting chamber 501, thereby increasing the overall strength of the water receiving device, preventing the deformation of the water receiving device from causing the distance between the inner and outer tubs to become smaller, thereby causing "collision with the tub" or even "grinding the tub" and other phenomena, thereby ensuring the stability of the washing and dehydration conditions of the washing tub.
