Description

Technical Field

[0001] This application relates to the technical field of washing machines, and more particularly to a washing machine with a washing function. Background Technology

[0002] A washing machine's drum structure includes an outer drum and an inner drum. The outer drum is fixed, and the inner drum is installed inside it. The motor's shaft passes through the bottom of the outer drum and connects to the inner drum. The motor drives the inner drum to rotate, causing it to move the clothes and perform the washing function. There is a certain gap between the inner and outer drums. The inner wall of the outer drum and the outer wall of the inner drum are surfaces that clothes cannot come into contact with. After long-term use, dirt and bacteria easily accumulate on the inner and outer walls of the outer and inner drums. Therefore, some washing machines integrate a self-cleaning system to achieve automatic cleaning. For example, Chinese patent CN217757999U discloses an outer drum structure for a drum washing machine, which has a spray element with several spray holes on the outer drum body. The spray element can spray water onto the outer wall of the inner drum for rinsing. However, to achieve rinsing of the entire outer wall of the inner drum, the spray element needs to be long enough and have a sufficient number of spray holes. The large number of spray holes leads to low water pressure, which obviously affects the rinsing effect. Therefore, the existing washing structure of drum washing machines has the problem of poor cleaning effect. Utility Model Content

[0028] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] A washing machine's drum structure includes an outer drum and an inner drum. The outer drum is fixed, and the inner drum is installed inside it. The motor's shaft passes through the bottom of the outer drum and connects to the inner drum. The motor drives the inner drum to rotate, causing it to move the clothes and perform the washing function. There is a certain gap between the inner and outer drums. The inner wall of the outer drum and the outer wall of the inner drum are surfaces that clothes cannot come into contact with. After long-term use, dirt and bacteria easily accumulate on the inner and outer walls of the outer and inner drums. Therefore, some washing machines integrate a self-cleaning system to achieve automatic cleaning. For example, Chinese patent CN217757999U discloses an outer drum structure for a drum washing machine, which has a spray element with several spray holes on the outer drum body. The spray element can spray water onto the outer wall of the inner drum for rinsing. However, to achieve rinsing of the entire outer wall of the inner drum, the spray element needs to be long enough and have a sufficient number of spray holes. The large number of spray holes leads to low water pressure, which obviously affects the rinsing effect. Therefore, the existing washing structure of drum washing machines has the problem of poor cleaning effect.

[0032] To overcome the above technical problems, refer to Figure 1-6 This embodiment provides a washing machine with a cleaning function, including a fixed outer drum 1, an inner drum 2, a drum motor 3, and a cleaning module 4. The inner drum 2 is disposed inside the fixed outer drum 1. The output shaft of the drum motor 3 passes through the bottom of the fixed outer drum 1 and connects to the inner drum 2, and the drum motor 3 can drive the inner drum 2 to rotate. The cleaning module 4 includes a mounting base 41, a translation drive mechanism 42, and a sprayer 43. The mounting base 41 is fixed to the fixed outer drum 1. The translation drive mechanism 42 is mounted on the mounting base 41. The sprayer 43 is mounted on the translation drive mechanism, and the sprayer 43 faces the outer wall of the inner drum 2. The translation drive mechanism 42 drives the sprayer 43 to reciprocate in a direction parallel to the axial direction, so that the sprayer 43 can reciprocate to rinse the outer wall of the inner drum 2.

[0033] Here, the axial direction refers to the direction of the central axis of the fixed outer cylinder 1 or inner drum 2. The sprayer 43 can move in a direction parallel to the axial direction. Combined with the rotational movement of the inner drum 2 itself, it can achieve comprehensive cleaning of the outer surface of the inner drum 2. The inner drum 2 includes drum side walls and drum bottom walls. To achieve cleaning of the drum bottom wall, the sprayer 43 can be set at an angle. Specifically, when the sprayer 43 moves to a position close to the bottom of the fixed outer cylinder 1, the sprayer 43 can be tilted towards the drum bottom wall, and the water sprayed by the sprayer 43 can rinse the drum bottom wall.

[0034] The washing machine with a cleaning function according to this embodiment has a cleaning module 4 installed inside the fixed outer drum 1. The cleaning module 4 can rinse and clean the outer wall of the inner drum 2. The cleaning module 4 includes a mounting base 41, a translation drive mechanism 42, and a sprayer 43. The sprayer 43 is mounted on the translation drive mechanism 42. During the cleaning operation, the translation drive mechanism 42 drives the sprayer 43 to reciprocate in a direction parallel to the axial direction. Combined with the rotational motion of the drum itself, the sprayer 43 can clean the entire outer wall of the drum. The sprayer 43 in this design can achieve single-point water output, thus ensuring effective water pressure. Providing higher water pressure results in better cleaning effects, effectively removing dirt and bacteria from the outer wall of the inner drum 2.

[0035] In one embodiment, combined with Figure 4-6 The translation drive mechanism 42 includes a motor 421, a transmission assembly 422, and a mounting block 423. The motor 421 is connected to the transmission assembly 422, the mounting block 423 is mounted on the transmission assembly 422, and the sprayer 43 is mounted on the mounting block 423. The motor 421 drives the transmission assembly 422 to rotate, and the transmission assembly 422 drives the mounting block 423 to reciprocate in a direction parallel to the axial direction.

[0036] Motor 421 is the power source of translation drive mechanism 42, responsible for providing the energy required to drive the sprayer 43 to move; transmission assembly 422 is the key component connecting motor 421 and mounting block 423, responsible for converting the rotational motion of motor 421 into the translational motion of mounting block 423; mounting block 423 is the mounting platform for sprayer 43, responsible for fixing sprayer 43 on transmission assembly 422 and moving it together. When motor 421 starts, it drives transmission assembly 422 to operate, and transmission assembly 422 converts the rotational motion of motor 421 into the translational motion of mounting block 423, causing mounting block 423 to reciprocate in a direction parallel to the axial direction of inner roller 2. Sprayer 43 mounted on mounting block 423 moves accordingly, realizing comprehensive rinsing of the outer wall of inner roller 2.

[0037] In one embodiment, the transmission assembly 422 includes a timing belt 4222 and two timing pulleys 4221 rotatably mounted on the mounting base 41. The timing belt 4222 is sleeved on the two timing pulleys 4221. The output shaft of the motor 421 is connected to one of the timing pulleys 4221. The mounting block 423 is connected to the timing belt 4222.

[0038] The synchronous belt 4222 is a toothed transmission belt that works in conjunction with the synchronous pulley 4221 to achieve precise synchronous transmission. The synchronous pulley 4221 is a wheel-shaped component that works in conjunction with the synchronous belt 4222, and its surface has tooth grooves that match the tooth profile of the synchronous belt 4222. The output shaft of the motor 421 is directly or through a reducer connected to one of the synchronous pulleys 4221 to provide power to drive the synchronous belt 4222. When the motor 421 starts, it drives the synchronous pulley 4221 connected to it to rotate. The rotating synchronous pulley 4221 transmits motion to the other synchronous pulley 4221 through the synchronous belt 4222, causing the two synchronous pulleys 4221 to rotate at the same speed. The mounting block 423 mounted on the synchronous belt 4222 moves together with the synchronous belt 4222, thereby driving the sprayer 43 to reciprocate in a direction parallel to the axial direction of the inner roller 2.

[0039] The combination of synchronous belt 4222 and synchronous pulley 4221 can achieve precise synchronous transmission, ensuring the stability and accuracy of the sprayer 43 during movement; at the same time, synchronous transmission has the characteristics of high transmission efficiency and low power loss, which can ensure that the power provided by motor 421 can be efficiently transmitted to sprayer 43.

[0040] In one embodiment, the mounting base 41 includes a base plate 411 and a mounting groove 412 connected to one side of the base plate 411. The base plate 411 is fixed to the fixed outer cylinder 1, and the transmission assembly 422 is disposed in the mounting groove 412.

[0041] The design of the base plate 411 and the mounting groove 412 enhances the stability and load-bearing capacity of the mounting base 41, ensuring the stability of the transmission assembly 422 and the sprayer 43 during movement.

[0042] In one embodiment, the inner wall of the mounting groove 412 is provided with a guide rail 4121, and the mounting block 423 is slidably connected to the guide rail 4121, so that the translation of the mounting block 423 is guided by the guide rail 4121.

[0043] The guide rail 4121 is set on the inner wall of the mounting groove 412, which serves to guide and support the mounting block 423. The guide rail 4121 ensures that the mounting block 423 can move stably along the predetermined path during translation, preventing it from deviating from the track or shaking.

[0044] In one embodiment, the fixed outer cylinder 1 is provided with an installation port 11, the installation groove 412 extends into the fixed outer cylinder 1 through the installation port 11, and the bottom plate 411 is fixed to the installation port 11.

[0045] The mounting port 11 is a specific opening formed on the fixed outer cylinder 1. Its main function is to provide a channel so that the mounting slot 412 of the mounting base 41 can be smoothly installed into the fixed outer cylinder 1. The purpose of setting the mounting port 11 in this solution is to facilitate the disassembly, assembly, maintenance and cleaning of the cleaning module 4. When it is necessary to disassemble, the cleaning module 4 can be disassembled directly without removing the inner roller 2.

[0046] In one embodiment, the outer wall of the fixed outer cylinder 1 is provided with a mounting frame 12 arranged around the edge of the mounting opening 11, and the bottom plate 411 is fixed to the mounting frame 12.

[0047] The mounting frame 12 on the outer wall of the fixed outer cylinder 1 not only provides a more stable support for fixing the base plate 411, but also enhances the structural strength around the mounting port 11, ensuring the reliability of the cleaning module 4 installation. During installation, the base plate 411 can be fixed to the mounting frame 12 by bolts or clips.

[0048] In one embodiment, a sealing ring is provided between the mounting frame 12 and the base plate 411.

[0049] By fitting tightly between the mounting frame 12 and the base plate 411, the sealing ring ensures the washing machine's airtightness during operation, preventing leaks. The sealing ring also provides cushioning and shock absorption, absorbing vibrations and impacts generated during operation.

[0050] In one embodiment, the base plate 411 is provided with a coupling hole, the motor 421 is disposed outside the fixed outer cylinder 1, and the output shaft of the motor 421 passes through the coupling hole and is connected to the synchronous pulley 4221.

[0051] By placing the motor 421 outside the fixed outer drum 1, damage to the motor 421 due to water contact can be effectively prevented. This design not only improves the waterproof performance of the washing machine but also extends the service life of the motor 421. Furthermore, placing the motor 421 externally facilitates its maintenance and replacement.

[0052] Effective sealing measures are required at the coupling hole to prevent water leakage. Auxiliary materials such as sealing rings and sealant can be used to enhance the sealing performance of the coupling hole.

[0053] In one embodiment, the sprayer 43 includes a nozzle and a water pipe. The fixed outer cylinder 1 is provided with a pipe passage hole. The nozzle is fixed on the mounting block 423. The water pipe extends through the pipe passage hole into the mounting groove 412 and connects to the nozzle.

[0054] The sprayer 43 mainly consists of a nozzle and a water pipe. The nozzle is responsible for spraying water onto the parts of the washing machine that need to be cleaned, while the water pipe is responsible for delivering water to the nozzle. In specific settings, the water pipe needs to be reserved with sufficient length in the mounting groove 412, and the part of the water pipe in the mounting groove 412 is a flexible hose so that the moving nozzle can drag the water pipe.
