Description

Technical Field

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

[0002] A washing machine is designed as a device for washing clothes by using electricity, and generally, the washing machine includes: an outer tub for containing washing water; an inner tub rotatably installed inside the tub; a pulsator rotatably installed at the bottom of the inner tub; a motor and a clutch configured to rotate the inner tub and the pulsator. When clothes and detergent are introduced into the inner tub, the pulsator stirs the washing water together with the clothes introduced into the inner tub, thereby removing stains from the clothes.

[0003] However, with the development of technology, the existing washing machine structure has certain structural disadvantages. For example, the existing washing machine generally has an outer barrel, and the main function of the outer barrel is to collect and discharge the water thrown out of the inner barrel during the dehydration process. The existence of the inner barrel in other processes leads to the following problems:

[0004] 1. During washing or rinsing, the washing water between the inner and outer barrels cannot be used, resulting in a waste of water.

[0005] 2. During washing or rinsing, due to the accumulation of water between the inner and outer barrels, dirt is accumulated on the outer wall of the inner barrel and the inner wall of the outer barrel, and is difficult or impossible to clean. As the washing machine is used for a long time, the washing effect and user experience are affected.

[0006] 3. Washing machines with the same specifications of the outer shell have limited capacity of the inner barrel due to the structure of the outer barrel. Expanding the capacity of washing machines with the same specifications of the outer shell is of great significance to the majority of users.

[0007] Based on the above problems, the development of existing washing machines is gradually moving towards "removing the outer barrel". There is an existing "outer barrel-free washing machine" that includes a hole-free inner barrel and a water collecting device arranged at the bottom of the hole-free inner barrel. A dehydration port is arranged on the barrel wall of the hole-free inner barrel at the upper part of the highest water level, and a dehydration waterway is installed on the barrel wall of the hole-free inner barrel. The dehydration waterway connects the dehydration port and the water collecting device to guide the dehydration drainage to the water collecting device for discharge. This "outer barrel-free washing machine" uses a dehydration waterway to guide the dehydration into the water collecting device. If there is lint blocking the dehydration waterway during dehydration and drainage, it will affect the dehydration and is not easy to clean. Therefore, how to achieve lint filtration for dehydration drainage in the "outer barrel-free washing machine" is crucial to whether the washing machine can work normally.

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

[0017] Furthermore, the mounting portion includes a mounting plate and a mounting column arranged on the mounting plate, and the mounting plate is assembled and fixed on the inner wall of the inner barrel through a connecting piece, the mounting column, and the barrel wall of the inner barrel, and the mounting column enables the mounting plate and the inner wall of the inner barrel to be spaced apart to form a water channel connected to the dehydration outlet, and the filter portion is a filter grille / filter rib arranged on the mounting plate, and the filter grille / filter rib is arranged on the mounting plate on the lower side of the dehydration outlet and / or on the mounting plate on at least one side of both sides of the dehydration outlet and / or on the mounting plate in front of the dehydration outlet.

[0018] Furthermore, a plurality of columns are arranged on the edge of the mounting plate located below the dehydration outlet, and the columns are arranged at intervals to form a lower filtering grid;

[0019] And / or, columns are arranged on the mounting plate at the edges of both sides of the dehydration outlet, and filter grilles on both sides are formed by spacing between the columns on both sides or between the columns on both sides and the columns on the lower side;

[0020] Preferably, the columnar body and the mounting plate are integrally formed.

[0021] Furthermore, the mounting column is arranged in the middle of the mounting plate, and the mounting column includes at least two, which are arranged on both sides of the dehydration outlet respectively, and a plurality of columnar bodies are arranged on the lower side of the mounting column on the mounting plate; the length of the mounting column on the side of the mounting plate close to the dehydration outlet is greater than the length of the columnar body, so that there is a gap between the columnar body and the barrel wall of the inner barrel;

[0022] Preferably, a box-shaped reinforcement body is arranged on the upper side of the mounting column on the mounting plate, and the length of the mounting column on the side of the mounting plate close to the dehydration outlet is greater than the length of the box-shaped reinforcement body on the side of the mounting plate close to the dehydration outlet, so that there is a gap between the columnar body and the barrel wall of the inner barrel, and between the box-shaped reinforcement body and the barrel wall of the inner barrel.

[0023] Furthermore, the filtering portion is a lint filter, and the mounting portion is a mounting frame for detachably mounting the lint filter.

[0038] A washing machine of the present invention is described in detail below with reference to the accompanying drawings:

[0039] like Figure 1-Figure 4 As shown, this embodiment provides a washing machine, comprising:

[0040] The inner barrel 5 is used to independently hold washing water when washing clothes;

[0041] The wire scrap filtering device 4 is arranged on the barrel wall of the inner barrel 5 and is used for filtering the wire scraps in the dehydrated drainage.

[0042] The inner barrel 5 of the washing machine of this embodiment can independently hold washing water when washing clothes to realize the water holding function, so the outer barrel design can be eliminated, which has the following beneficial effects:

[0043] 1. The capacity of the inner drum can be increased while the volume of the shell remains unchanged, thus achieving the capacity expansion effect of the washing machine.

[0044] 2. During the washing process, water only exists in the inner barrel, which avoids the problem of water accumulation between the inner and outer barrels of traditional washing machines causing the inner wall of the outer barrel and the outer wall of the washing barrel to "hide dirt and grime", and has a better washing effect.

[0045] 3. The outer barrel is eliminated, and the inner barrel is used as a water barrel. During the washing process, no water is stored between the inner and outer barrels, which reduces the amount of washing water and saves washing water.

[0046] While achieving "no outer drum", the washing machine of this embodiment is provided with a lint filtering device 4 on the inner drum 5 for filtering lint in the dehydration and drainage, thereby achieving lint filtering during the dehydration and drainage process, preventing the lint in the dehydration and drainage from blocking the dehydration and drainage channel, and ensuring the dehydration effect.

[0047] As an implementation method of this embodiment, in order to realize the function of the inner barrel 5 to hold water, the inner barrel of this embodiment adopts a "hole-free" design, that is, except for the dehydration outlet 3 set on the barrel wall and above the highest water level, the rest of the inner barrel is in a closed state. In this way, during washing and rinsing, the water inlet of the washing machine cannot reach the position of the dehydration outlet, realizing the water holding function of the inner barrel, and during dehydration, the high-speed rotation of the inner barrel can be controlled by the program to throw the dehydration to the dehydration outlet and discharge it. Therefore, the washing machine of this embodiment realizes the water holding washing and dehydration drainage of the inner barrel through the "hole-free" inner barrel and the corresponding dehydration outlet design.

[0048] At the same time, for the washing machine with the above-mentioned structural design, the lint filtering device 4 described in this embodiment is arranged on the dehydration outlet 3 and / or at the upstream position of the dehydration outlet 3 and / or at the downstream position of the dehydration outlet 3, thereby realizing the lint filtering on the dehydration drainage path during the dehydration process to prevent the lint from clogging and affecting the dehydration drainage.

[0049] The setting position of the wire scrap filtering device 4 of this embodiment can be set on the dehydration outlet 3, or can be set at the upstream position of the dehydration outlet 3, or can be set at the downstream position of the dehydration outlet 3, or can be set at any two positions or all three positions of the above three positions, as long as the wire scraps can be filtered during the dehydration and drainage process. The wire scrap filtering device has different setting methods and structural designs for different setting positions.

[0050] As an implementation mode of this embodiment, the wire scrap filtering device 4 described in this embodiment includes an installation part and a filtering part, the installation part is installed on the inner wall of the inner barrel 5, and the filtering part is arranged on the lower side of the dehydration outlet 3 and / or at least one side of the two sides of the dehydration outlet 3 and / or the front side of the dehydration outlet 3; the dehydrated drainage enters the dehydration outlet and is discharged after filtering the wire scraps through the filtering part.

[0051] The lint filtering device 4 of the above embodiment is arranged on the inner wall of the inner barrel and is located upstream of the dehydration outlet. In this way, when dehydrating and draining water, it needs to be filtered by the lint filtering device 4 first, and then discharged through the dehydration outlet 3. From the beginning of dehydration, lint is prevented from entering the dehydration outlet 3, and it is also easier to clean the lint.

[0052] Since the dehydration outlet 3 of the present embodiment is arranged at the upper part of the inner barrel, during dehydration and drainage, the water inside the inner barrel moves from the lower part to the upper part and is discharged from the inner barrel through the dehydration outlet 3. From the drainage path, it can be seen that the filtering part of the lint filtering device 4 of the present embodiment is arranged on the lower side of the dehydration outlet 3 and / or at least one side of the two sides of the dehydration outlet 3 and / or in front of the dehydration outlet 3, so that the dehydration and drainage path must pass through the filtering action of the filtering part of the lint filtering device 4 before entering the dehydration outlet 3 for discharge.

[0053] Preferably, according to the dehydration drainage path, the filtering portion of the lint filtering device 4 of this embodiment is at least arranged on the lower side of the dehydration outlet 3 .

[0054] like Figure 3 and Figure 4 As shown, the mounting portion described in this embodiment includes a mounting plate 404 and a mounting column 402 arranged on the mounting plate 404, and the mounting plate 404 is assembled and fixed on the inner wall of the inner barrel 5 through a connecting piece, the mounting column 402, and the barrel wall of the inner barrel 5. The mounting column 402 allows the mounting plate 404 and the inner wall of the inner barrel 5 to be spaced apart to form a waterway connected to the dehydration outlet 3, and the filtering portion is a filtering grille / filter rib arranged on the mounting plate, and the filtering grille / filter rib is arranged on the mounting plate 404 on the lower side of the dehydration outlet 3 and / or on the mounting plate 404 on at least one side of both sides of the dehydration outlet 3 and / or on the mounting plate 404 in front of the dehydration outlet 3.

[0055] As an implementation mode of this embodiment, a plurality of columns 403 are arranged on the edge of the mounting plate 404 located at the lower side of the dehydration outlet 3, and the columns 403 are arranged at intervals to form a lower filtering grid.

[0056] And / or, columns 403 are arranged on the mounting plate 404 at the edges of both sides of the dehydration outlet 3, and filtering grilles on both sides are formed by spacing between the columns 403 on both sides or between the columns 403 on both sides and the columns 403 on the lower side.

[0057] Preferably, in this embodiment, columns 403 are respectively arranged on the mounting plate 404 at the lower side and both sides of the dehydration outlet 3, so that the lower side and both sides of the dehydration outlet 3 can be surrounded, thereby achieving comprehensive filtration of the wire scraps entering the dehydration outlet 3, and having a better wire scrap filtration effect.

[0058] Preferably, the columnar body 403 and the mounting plate 404 are integrally formed.

[0059] In addition, as another implementation of this embodiment, the filter portion of this embodiment may also adopt a horizontally arranged rib structure, and the rib structure needs to be spaced apart from the inner wall of the inner barrel to achieve the purpose of entry and wire scrap filtering. This embodiment may also adopt a rib structure combined with a filter grille, for example, a filter grille is provided on the lower side of the mounting plate 404, and rib structures are provided on both sides of the mounting plate 404.

[0060] Furthermore, the mounting column 402 is arranged in the middle of the mounting plate 404, and the mounting column 402 includes at least two, which are respectively arranged on both sides of the dehydration outlet 3, and a plurality of columnar bodies 403 are arranged on the mounting plate 3 at the lower side of the mounting column 402; the length of the mounting column 403 located on the side of the mounting plate 404 close to the dehydration outlet 3 is greater than the length of the columnar body 403, so that there is a gap between the columnar body 403 and the barrel wall of the inner barrel 5.

[0061] Preferably, a box-shaped reinforcement body 401 is arranged on the mounting plate 404 on the upper side of the mounting column 402, and the length of the mounting column 402 on the side of the mounting plate 404 close to the dehydration outlet 3 is greater than the length of the box-shaped reinforcement body 401 on the side of the mounting plate 404 close to the dehydration outlet 3, so that there is a gap between the columnar body 403 and the barrel wall of the inner barrel 5, and between the box-shaped reinforcement body 401 and the barrel wall of the inner barrel 5.

[0062] In summary, in this embodiment, filter grilles are added on the lower side and left and right sides of the dehydration outlet 3 to prevent larger pieces of wire scraps from entering the dehydration outlet 3 and causing blockage. The wire scraps attached to the filter grilles can fall off the filter grilles by themselves due to gravity and water scouring, without hindering drainage.

[0063] In order to discharge the dehydrated water in the inner tub 5 out of the inner tub 5, the washing machine of this embodiment further comprises a drainage channel 2 arranged on the barrel wall of the inner tub 5 and connected to the dehydration outlet 3, and the drainage channel 2 and the lint filter 4 are fixedly connected to the inner tub 5 through the same connecting piece. The drainage channel 2 and the lint filter 4 of this embodiment are fixedly connected to the inner tub 5 by the same connecting piece, which simplifies the installation structure and installation process.

[0064] Preferably, the connecting piece passes through the upper part of the drainage channel 2, the barrel wall of the inner barrel 5 and the mounting column 402 of the lint filter 4 in sequence for assembly.

[0065] The washing machine of this embodiment further comprises a water collecting device 6 for collecting the water drained from the inner tub 5. The water collecting device 6 has a water collecting cavity inside, and the drainage channel 2 is connected to the water collecting cavity of the water collecting device 6. Specifically, the water collecting device 6 of this embodiment is arranged at the bottom of the inner tub 5.

[0066] Furthermore, a plurality of dehydration outlets 3 are arranged at the barrel opening of the inner barrel 5 of the present embodiment, and the drainage waterway includes a plurality of waterways, which correspond to the dehydration outlets 3 one by one, and the upper end of the drainage waterway is connected to the dehydration outlet 3, and the lower end extends to the water collection chamber of the water collection device 6. A lint filter 4 is arranged in the inner barrel of the present embodiment corresponding to each dehydration outlet 3.

[0067] As an implementation mode of this embodiment, the washing machine of this embodiment also includes a balancing ring 9 installed on the barrel mouth of the inner barrel 5, and the lint filter device 4 is an independent component. The mounting portion of the lint filter device 4 is spaced apart from or in contact with the bottom of the balancing ring 9; or, the lint filter device 4 is integrally formed with the balancing ring 9.

[0068] In this embodiment, a balancing ring 9 is arranged on the barrel mouth of the inner barrel 5, and the dehydration outlet 3 of the inner barrel 5 is arranged at the barrel mouth and is blocked by the balancing ring 9, so that the inner barrel 5 can achieve a visual "hole-free" effect, thereby improving the integrity of the inner barrel.

[0069] Regarding the structure of the wire scrap filtering device of this embodiment, as another implementation mode of this embodiment, the filtering part described in this embodiment is a wire scrap filter, and the mounting part is an installation frame for detachably mounting the wire scrap filter, and the installation frame is arranged on the dehydration outlet, so that the wire scrap filter can be disassembled for wire scrap cleaning.

[0070] Specifically, the lint filter of this embodiment includes a filter mesh bag and a filter mesh frame, and the filter mesh frame is detachably mounted on the mounting frame. Alternatively, the lint filter is a box-type lint filter, and the box-type lint filter is detachably mounted on the mounting frame.

[0071] Regarding the installation position of the lint filter device of this embodiment, as an implementation method of this embodiment, the washing machine of this embodiment also includes a drainage channel 2 arranged on the barrel wall of the inner barrel 5 and connected to the dehydration outlet 3, and the lint filter device is detachably arranged in the drainage channel 2, which can be disassembled and cleaned while realizing lint filtering. A driving device is installed on the bottom wall of the water collection device of this embodiment, and the driving device has an inner barrel shaft and a pulsator shaft for driving the inner barrel and the pulsator 8 to rotate.

[0072] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
