Description

Technical Field

[0001] This invention relates to the field of washing equipment technology, and more particularly to an improvement in the structure of a washing machine. Background Technology

[0002] Existing pulsator washing machines are equipped with pulsators to improve the washing effect of clothes. These pulsators have raised ribs. During washing, the rotation of the pulsator drives the raised ribs to rotate, thus achieving a rubbing and washing effect on the clothes. However, because the raised ribs come into direct contact with and rub against the clothes when the pulsator rotates and rubs, especially when the motor is rotating at high speed, the friction between the raised ribs and the clothes is intensified. This not only causes wear and damage to the washed clothes, but also results in poor washing performance. Summary of the Invention

[0003] To address the problem that existing pulsator washing machines often cause severe wear and tear on clothes and have poor washing results, this invention provides a washing machine that uses a spiral water guide channel to swirl water in and then sprays it onto the clothes through a spray nozzle. This method avoids washing clothes through friction, thus solving the problem of severe wear and tear on clothes. Furthermore, this invention's washing machine can perform forward and reverse washing during the washing process, ensuring optimal washing results.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] The second spiral water guiding channel has a second spray section connected to it, and the spiral direction of the second spiral water guiding channel is opposite to that of the first spiral water guiding channel.

[0012] The spraying component cooperates with the rotating base and forms a first spraying channel and a second spraying channel that are respectively connected to the first spiral water guiding channel and the second spiral water guiding channel. A third spraying part that sprays into the inner cylinder is formed on both the first spraying channel and the second spraying channel.

[0013] A drive unit is connected to the rotary spray device to drive the rotary spray device to rotate.

[0014] In some embodiments of this application:

It includes a first spiral water-guiding rib and a second spiral water-guiding rib with opposite directions of rotation. The central water-guiding rib is located between the first spiral water-guiding rib and the second spiral water-guiding rib. A first spiral water-guiding channel is formed between the central water-guiding rib and the first spiral water-guiding rib, and a second spiral water-guiding channel is formed between the central water-guiding rib and the second spiral water-guiding rib.

[0054] Example 1

[0055] This invention provides an embodiment of a washing machine, comprising:

[0056] outer cylinder 100;

[0057] The inner cylinder 200 is disposed inside the outer cylinder 100, and a first water-containing space 300 is formed between the inner cylinder 200 and the outer cylinder 100.

[0058] During washing, external water flows into the first water-containing space 300 between the outer drum 100 and the inner drum 200 through the water inlet provided on the outer drum 100.

[0059] In order to allow the water in the first water-containing space 300 to enter the inner drum 200 for washing, multiple water inlets are provided on the inner drum 200. The water inlets are arranged in multiple rows, with multiple inlets in each row. Each row of water inlets is evenly spaced along the height of the inner drum 200.

[0060] Existing pulsator washing machines are equipped with pulsators to improve the washing effect of clothes. The pulsator has raised ribs, which rotate when the pulsator rotates, thus achieving the effect of rubbing and washing clothes. However, because the pulsator comes into direct contact with the clothes when it rotates, especially at high speeds, it can cause some wear and damage to the clothes being washed.

[0061] To address the problem that existing pulsator washing machines easily cause wear and damage to clothes during washing, this embodiment proposes a novel washing machine structure that directly eliminates the pulsator structure.

[0062] Specifically, the washing machine includes a rotating spray device 400, which is disposed inside the inner drum 200, and a second water-containing space 500 is formed between the device and the inner drum 200 and communicates with the first water-containing space 300.

[0063] In order to achieve the connection between the first water-containing space 300 and the second water-containing space 500, so that the water in the first water-containing space 300 can flow into the second water-containing space 500, in some embodiments of this application, a connecting portion 110 for connecting the first water-containing space 300 and the second water-containing space 500 is provided on the bottom wall and / or side wall of the inner cylinder 200.

[0064] In some embodiments, the connecting part 110 is a connecting hole opened on the bottom wall of the inner cylinder 200. Multiple connecting holes are provided and are equally spaced along the circumferential direction of the bottom wall of the inner cylinder 200.

[0065] Alternatively, multiple connecting holes can be provided and evenly distributed across the bottom wall of the inner cylinder 200 to guide the water flow in the first water-containing space 300 into the second water-containing space 500.

[0066] The shape of the connecting hole can be elliptical, rectangular, or square, etc., and there are no specific restrictions.

[0067] In some other embodiments, the connecting part 110 is a water flow connecting hole opened on the side wall of the inner cylinder 200. Multiple water flow connecting holes can be opened along the circumference of the side wall of the inner cylinder 200, and the connecting holes are opened on the side wall near the bottom wall of the inner cylinder 200.

[0068] The shape of the connecting hole can be arbitrary and is not specifically limited. Water in the first water-containing space 300 can be introduced into the second water-containing space 500 through the connecting part 110 opened on the side wall of the inner cylinder 200.

[0069] The rotary spray device 400 includes:

[0070] A rotating base 410 has a spiral water guiding channel formed on it, the spiral water guiding channel comprising:

[0071] The first spiral water guiding channel 411 is located inside and connected to the second water holding space 500. A first spray section 4111 connected to the first spiral channel is formed on the first spiral channel. A first water inlet section is also provided on the first spiral water guiding channel 411. The first water inlet section is a first water inlet located at the end of the first spiral water guiding channel 411.

[0072] Water in the second water-containing space 500 can enter the second spiral water guiding channel 412 through the first water inlet, and then be sprayed into the inner cylinder 200 through the first spray section 4111.

[0073] In some embodiments of this application: the first spray section 4111 is a first spray hole, and the first spray hole is disposed on the rotating base 410, and there are multiple first spray holes arranged along the radial direction of the rotating base 410.

[0074] When the first spray hole is set, its diameter decreases continuously from the inside to the outside along the radial direction of the rotating base 410. Because the first spiral water guide channel 411 draws water in through the spiral force generated by its rotation, water is drawn into the interior along the spiral direction during rotation. The internal water pressure is higher near the center of the rotating base 410, resulting in a higher spray height and a greater impact on clothing. Conversely, the water pressure is lower at the outer position of the first spray hole, further away from the center of the rotating base 410, resulting in a lower spray height and a less forceful impact on clothing. Since the impact force on the clothes is relatively small, in order to ensure that the multiple first spray holes arranged in the radial direction along the rotating base 410 have the same rinsing effect on the clothes, the outer hole diameter is set to be smaller, which is equivalent to reducing the diameter of the first spray hole. This can achieve a throttling effect. By reducing the hole diameter, the rinsing force of the water flow is increased. At the same time, since the water pressure of the inner first spray hole itself is larger, the hole diameter can be increased to reduce its impact force on the clothes. This ensures that the water flow at each spray point can apply a uniform rinsing force to the clothes being rinsed, thus ensuring the rinsing effect and cleanliness of the clothes.

[0075] The second spiral water guiding channel 412 has a second spray section 4121 connected to it, and the spiral direction of the second spiral water guiding channel 412 is opposite to that of the first spiral water guiding channel 411.

[0076] In order to allow water to flow from the second water-containing space 500 into the second spiral water-guiding channel 412, a second water inlet is provided on the second spiral water-guiding channel 412. The second water inlet is a second water inlet located at the end of the second spiral water-guiding channel 412 to facilitate water flow.

[0077] In some embodiments of this application: the second spray section 4121 is a second spray hole, and the second spray hole is disposed on the rotating base 410, and there are multiple second spray holes arranged along the radial direction of the rotating base 410.

[0078] The second spray hole can be circular, elliptical, or any other shape; there are no specific restrictions.

[0079] When setting the diameter of the second spray hole, it can also be gradually increased from the outside to the inside along the radial direction of the rotating base 410 to achieve a uniform spray rinsing effect.

[0080] In this embodiment, by setting a first spiral water guide channel 411 and a second spiral water guide channel 412 with opposite rotation directions, it can be ensured that during washing, water can be sprayed outward through the first spiral water guide channel 411 in one direction, such as counterclockwise, and then sprayed outward through the second spiral water guide channel 412 in the opposite direction. By rinsing and spraying the clothes in the washing machine from two opposite directions, the washing effect of the clothes is guaranteed.

[0081] The spraying component 420 cooperates with the rotating base 410 and forms a first spraying channel and a second spraying channel that are respectively connected to the first spiral water guiding channel 411 and the second spiral water guiding channel 412. A third spraying part 450 that sprays into the inner cylinder 200 is formed on both the first spraying channel and the second spraying channel.

[0082] A drive device 600 is connected to the rotary spray device 400 and is used to drive the rotary spray device 400 to rotate.

[0083] In some embodiments, the drive device 600 is a drive motor, which is directly connected to the rotating base 410 to drive the rotating base 410 and the spraying component 420 that cooperates with the rotating base 410 to rotate synchronously.

[0084] To facilitate the assembly of the motor, an insertion hole is provided at the middle position of the rotating base 410 during setup.

[0085] The drive motor includes a transmission shaft, and clearance holes are provided on the bottom walls of the outer cylinder 100 and the inner cylinder 200 to allow the drive motor to pass.

[0086] During assembly, the drive motor passes through the clearance hole and is then inserted and fixed inside the insertion hole. To ensure a tight fit between the two, a key connection structure can be installed between the drive shaft and the insertion hole during setup.

[0087] When the drive motor is inserted into the insertion hole, the rotation of the motor can drive the rotating base 410 to rotate.

[0088] In this embodiment, when the washing machine is in use, the drive device 600 can be controlled to move. For example, in the first use state, the drive device 600 can be controlled to rotate forward. When the drive device 600 rotates forward, it drives the rotating base 410 to rotate.

[0089] For ease of description, in this embodiment, the spiral method of the first spiral water guiding channel 411 is opposite to the forward rotation direction of the motor, and the spiral water guiding channel 412 is opposite to the reverse rotation direction of the motor. When the drive motor rotates, it drives the rotating base 410 connected to it to rotate. At this time, the rotation direction of the drive motor is opposite to that of the first spiral water guiding channel.

[0090] The channels rotate in opposite directions, which can drive the first spiral water guiding channel 411 to rotate. At the same time, water is swirled into the first spiral water guiding channel 411 through the first water inlet.

[0091] The water flow that is screwed into the first spiral water guiding channel 411 is sprayed into the inner drum 200 through the first spray hole on the rotating base 410, so as to spray the clothes in the inner drum 200 and achieve the effect of spray washing the clothes in the inner drum 200.

[0092] Meanwhile, as the drive motor rotates continuously, the first spiral water guiding channel 411 continuously spirals in new water flow to replenish the water flow sprayed from the first spray section 4111, so that the first spray section 4111 can spray outwards continuously during the washing process to ensure the washing effect on the clothes.

[0093] When the drive motor reverses, it will rotate in the opposite direction to the second spiral water guide channel 412. During the rotation, it will drive the second spiral water guide channel 412 to continuously draw water from the second water inlet and finally spray it out from the second spray section 4121 into the inner cylinder 200.

[0094] In this embodiment, the washing machine mainly sprays water onto the clothes through the first spray section 4111 and the second spray section 4121 to achieve the washing of the clothes. It does not directly contact or rub the clothes, thus effectively avoiding the problem of damage to the clothes caused by contact and friction.

[0095] In this embodiment, the washing machine can spray and clean clothes from two different directions, forward and reverse, by driving the motor to rotate forward and reverse. The combination of forward and reverse rotation ensures the washing effect of the clothes.

[0096] In some embodiments of this application, one implementation of the first spiral water guiding channel 411 and the second spiral water guiding channel 412 is as follows:

[0097] The first spiral water guiding channel 411 and the second spiral water guiding channel 412 are arranged along the radial direction of the rotating base 410 and are arranged alternately along the circumferential direction of the rotating base 410.

[0098] In the setup, multiple first spiral water guiding channels 411 and multiple second spiral water guiding channels 412 are provided. The multiple first spiral water guiding channels 411 and multiple second spiral water guiding channels 412 are arranged alternately along the radial direction of the rotating base 410.

[0099] When the drive device 600 rotates forward, it can drive multiple first spiral water guiding channels 411 arranged circumferentially along the rotating base 410 to draw water and spray water into the inner drum 200 through multiple first spray sections 4111 connected to the first spiral water guiding channels 411, thereby realizing the spraying and cleaning of clothes located inside the inner drum 200 in a clockwise circumferential direction.

[0100] Meanwhile, when the drive device 600 rotates forward, in addition to being sprayed out from the first spray section 4111, a portion of the water entering the first spiral water guiding channel 411 also enters the first spray channel connected to the first spiral water guiding channel 411, and is sprayed into the inner drum 200 through the third spray section 450 on the first spray channel. The cooperation between the first spray section 4111 and the third spray section 450 achieves a double-layer spraying effect on the water flow, which increases the washing effect on clothes.

[0101] When the drive device 600 reverses, it can drive multiple second spiral water guiding channels 412 to draw water and spray it into the clothes inside the inner drum 200 in a counterclockwise direction through multiple second spray sections 4121. At the same time, part of the water flow in the second spiral water guiding channel 412 enters the second spray channel and is sprayed into the inner drum 200 through the third spray section 450 in the second spray channel. Together with the second spray section 4121, it achieves the spray rinsing effect on the clothes.

[0102] As one embodiment of the first spiral water guiding channel 411 and the second spiral water guiding channel 412, the following structural implementation is provided: a central water guiding rib 413 and a spiral water guiding rib are formed on the rotating base 410, and the central water guiding rib 413 extends along the radial direction of the rotating base 410.

[0103] The spiral water-guiding ribs are arranged radially along the rotating base 410, and include a first spiral water-guiding rib 414 and a second spiral water-guiding rib 415 with opposite directions of rotation. The intermediate water-guiding rib 413 is located between the first spiral water-guiding rib 414 and the second spiral water-guiding rib 415. A first spiral water-guiding channel 411 is formed between the intermediate water-guiding rib 413 and the first spiral water-guiding rib 414, and a second spiral water-guiding channel 412 is formed between the intermediate water-guiding rib 413 and the second spiral water-guiding rib 415.

[0104] The water-guiding rib 413 is a straight rib that extends outward from the center of the rotating base 410 along the radial direction of the rotating base 410 to the outer end face of the rotating base 410.

[0105] The first spiral water guide rib 414 and the second spiral water guide rib 415 are respectively arranged on both sides of the central water guide rib 413 and rotate in opposite directions, so as to form an adjacent first spiral water guide channel 411 and second spiral water guide channel 412 after cooperating with the central water guide rib 413.

[0106] During installation, multiple sets of the central water guide rib 413, the second spiral water guide rib 415, and the second spiral water guide rib 415 are arranged circumferentially along the rotating base 410 to form multiple first spiral water guide channels 411 and second spiral water guide channels 412.

[0107] By setting the central water-guiding rib 413 in conjunction with the first spiral water-guiding rib 414 and the second spiral water-guiding rib 415 on both sides, material can be saved and it is convenient to directly form a single piece through a mold.

[0108] In other embodiments of this application, multiple sets of opposing first spiral water-guiding ribs 414 and multiple sets of opposing second spiral water-guiding ribs 415 can be directly protruded on the rotating base 410. A first spiral water-guiding channel 411 is formed between two opposing and adjacent first spiral water-guiding ribs 414, and a second spiral water-guiding channel 412 is formed between adjacent and opposing second spiral water-guiding ribs 415. The first spiral water-guiding channel 411 and the second spiral water-guiding channel 412 can be arranged alternately.

[0109] Another embodiment of the first spiral water guiding channel 411 and the second spiral water guiding channel 412 in this embodiment is as follows: multiple sets of the first spiral water guiding channel 411 are provided, multiple sets of the second spiral water guiding channel 412 are provided, a first spiral channel group is formed between at least two adjacent sets of the first spiral water guiding channel 411, and a second spiral channel group is formed between at least two adjacent sets of the second spiral water guiding channel 412. The first spiral channel group and the second spiral channel group are arranged alternately along the circumference of the rotating base.

[0110] That is, when setting up, the first spiral water guiding channel 411 can be set up in at least 2 adjacent groups, such as 2 groups, 3 groups, etc.

[0111] For example, the first spiral channel group can be configured as consisting of two groups of first spiral water guiding channels 411, or it can be configured as three adjacent groups of first spiral water guiding channels 411.

[0112] Similarly, the second spiral channel group can also be configured to consist of two groups of second spiral water guiding channels 412, or three adjacent groups of first spiral water guiding channels 411.

[0113] During the arrangement, the first spiral channel group and the second spiral channel group are arranged alternately along the circumference of the rotating base 410.

[0114] By arranging the first spiral channel group and the second spiral channel group alternately along the rotating base 410, it is also possible to spray and rinse the clothes located inside the inner drum 200 from the circumferential direction in a clockwise or counterclockwise direction during spraying.

[0115] When the system rotates in the forward direction, multiple sets of first spiral channels spray water outwards simultaneously; when the system rotates in the reverse direction, multiple sets of second spiral channels spray water outwards.

[0116] In one embodiment of the first spiral water guiding channel 411 of the first spiral channel group and the second spiral water guiding channel 412 of the second spiral channel group in this embodiment, a plurality of third spiral water guiding ribs and a plurality of fourth spiral water guiding ribs are formed on the rotating base 410, a first spiral water guiding channel 411 is formed between adjacent third spiral water guiding ribs, and a second spiral water guiding channel 412 is formed between adjacent fourth spiral water guiding ribs.

[0117] That is, the first spiral water guiding channel 411 is formed by two adjacent third spiral water guiding ribs with the same direction of rotation;

[0118] The second spiral water guiding channel 412 is also formed by two adjacent fourth spiral water guiding ribs with the same direction of rotation.

[0119] The first spiral channel group consists of multiple adjacent third spiral water guide ribs, while the second spiral channel group consists of multiple adjacent third spiral water guide ribs.

[0120] The second spray section 4121 and the first spray section 4111 have the same structure.

[0121] In some embodiments of this application: the first spray section 4111 and the second spray section 4121 are symmetrically arranged on both sides of the spray component 420.

[0122] The first spray section 4111 and the second spray section 4121 are arranged on both sides of the spray component 420 to cooperate with the spray component 420 to achieve a better spraying effect.

[0123] In some embodiments of this application: the first spray channel includes interconnected:

[0124] The guide channel is formed by the rotating base 410 and the spraying component 420 and is arranged radially along the rotating base 410.

[0125] In some embodiments of this application: the spray component 420 includes a spray body 421 and a spray arm 422, and a guide groove 418 is formed on the rotating base 410. The spray body 421 is embedded in the guide groove 418 and forms the guide channel between the spray body 421 and the guide groove 418.

[0126] The spray body 421 is a spray plate, which is assembled on the rotating base 410.
