[0024] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0025] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0027] Modern washing machines now feature a drying function, integrating efficient components such as a fan and electric heater. When drying mode is activated, hot air rapidly flows into the washing drum, rapidly drying clothes and significantly saving the user time and energy. However, current washing machines with drying functions still face several challenges: the drum and fan require separate motors, which not only increases manufacturing costs but also makes the washing machine bulkier and occupies more space.

[0028] In order to overcome the above technical problems, refer to Figure 1-5 This embodiment provides a washing machine with a drying function, including a dual-shaft motor 2, a washing drum 1 and a blower 3. The dual-shaft motor 2 includes a first output shaft 21 and a second output shaft 22; the washing drum 1 is transmission-connected to the first output shaft 21, and the washing drum 1 is driven to rotate by the first output shaft 21; the second output shaft 22 is provided with a clutch 4, and the clutch 4 can be switched between a disengaged state and an engaged state. In the disengaged state, the second output shaft 22 rotates independently relative to the blower 3. In the engaged state, the blower 3 is transmission-connected to the second output shaft 22 via the clutch 4, and the blower 3 is driven to rotate by the second output shaft 22.

[0029] The washing machine with a drying function of this embodiment is provided with a dual-shaft motor 2. The first output shaft 21 and the second output shaft 22 of the dual-shaft motor 2 are respectively connected to the washing drum 1 and the blower 3, thereby achieving the purpose of synchronously driving the washing drum 1 and the blower 3 using a single dual-shaft motor 2. Compared with conventional solutions that require two motors, this solution saves one motor, reducing manufacturing costs, space, and the overall size of the washing machine. In addition, this solution also provides a clutch 4 between the second output shaft 22 and the blower 3. When the drying function is not required, the clutch 4 can be switched to a disengaged state, and the second output shaft 22 will not drive the blower 3, thus avoiding unnecessary blowing and saving energy. When the drying function is required, the clutch 4 is switched to an engaged state, and the second output shaft 22 can drive the blower 3 normally.

[0030] I understand. Figure 1 The figure shows the internal structure of a washing machine with a drying function. Generally, a washing machine includes a washing machine housing, within which a washing drum 1, a dual-shaft motor 2, and a fan 31 are mounted. To provide hot, drying air, an electric heater is also provided. Air driven by a blower 3 is heated by the heater and then transported to the washing drum 1 to accelerate drying of clothes.

[0031] In one embodiment, the clutch 4 includes a clutch sleeve 41 and a clutch driving member 42. The clutch sleeve 41 is slidably mounted on the second output shaft 22. The clutch driving member 42 is used to drive the clutch sleeve 41 to move axially relative to the second output shaft 22, thereby driving the clutch sleeve 41 close to the blower 3 to enter the engaged state, or driving the clutch sleeve 41 away from the blower 3 to enter the disengaged state.

[0032] The clutch sleeve 41 is cleverly slidably mounted on the second output shaft 22. This design allows the clutch sleeve 41 to move axially along the second output shaft 22, and the second output shaft 22 drives the clutch sleeve 41 to rotate. The clutch drive member 42 is responsible for driving the clutch sleeve 41 to move. When the clutch sleeve 41 approaches the blower 3 and enters the engaged state, the rotating clutch sleeve 41 drives the blower 3 to rotate. When the clutch sleeve 41 moves away from the blower 3 and enters the disengaged state, the second output shaft 22 alone drives the clutch sleeve 41 to rotate, while the blower 3 remains stationary.

[0033] In one embodiment, the blower 3 includes a fan 31, and the fan 31 includes a fan shaft 311. The fan shaft 311 is provided with an engagement groove 3111 at one end close to the clutch 4, and the clutch sleeve 41 is provided with engagement teeth 411 corresponding to the engagement groove 3111. In the engaged state, the engagement teeth 411 are engaged with the engagement groove 3111; in the disengaged state, the engagement teeth 411 are disengaged from the engagement groove 3111.

[0034] When the clutch 4 is engaged, the engaging teeth 411 on the clutch sleeve 41 precisely engage with the engaging grooves 3111 on the fan shaft 311, forming a secure connection. Thus, when the second output shaft 22 rotates, its power is transmitted to the fan shaft 311 through the clutch sleeve 41 and the engaging teeth 411, thereby driving the fan 31 to rotate. When the clutch 4 is disengaged, the engaging teeth 411 on the clutch sleeve 41 disengage from the engaging grooves 3111 on the fan shaft 311, and there is no longer a connection between the clutch sleeve 41 and the fan shaft 311. Thus, even if the second output shaft 22 rotates, its power cannot be transmitted to the fan shaft 311, causing the fan 31 to stop, thereby avoiding unnecessary energy consumption.

[0035] In specific applications, the blower 3 further includes a volute, and the fan 31 is installed in the volute. The volute can effectively gather and guide wind.

[0036] In one embodiment, one end of the engaging tooth 411 for inserting into the engaging groove 3111 is configured to be tapered.

[0037] The end of the engaging tooth 411 is configured to be tapered, which makes the engaging tooth 411 smoother when inserted into the engaging groove 3111 and improves the engaging efficiency.

[0038] In one embodiment, a plurality of protrusions 3112 are evenly arranged on the outer circumference of the fan shaft 311 , and a plurality of engagement grooves 3111 are formed between the protrusions 3112 ; and one end of the protrusion 3112 close to the clutch sleeve 41 is configured to be conical.

[0039] Similarly, the end of the protrusion 3112 is configured to be tapered, which makes the engagement tooth 411 smoother when inserting into the engagement groove 3111, thereby improving the engagement efficiency.

[0040] In one embodiment, the second output shaft 22 is provided with a guide groove 221 extending in the axial direction, the inner wall of the clutch sleeve 41 is provided with a guide key 412 corresponding to the guide groove 221, the clutch sleeve 41 is sleeved on the second output shaft 22, and the guide key 412 is embedded in the guide groove 221.

[0041] The coordinated arrangement of the guide key 412 and the guide slot 221 can satisfy the axial movement of the clutch sleeve 41 to realize the clutch process, and can also effectively connect the second output shaft 22 and the clutch sleeve 41, so that the second output shaft 22 can stably drive the clutch sleeve 41 to rotate.

[0042] In one embodiment, the clutch drive member 42 includes a return spring 422 and an elastic telescopic electromagnet 421. A shaft shoulder is provided in the middle of the second output shaft 22. The return spring 422 is sleeved on the second output shaft 22, and one end of the return spring 422 abuts against the shaft shoulder, and the other end abuts against the clutch sleeve 41. The clutch sleeve 41 is driven into the engaged state by the return spring 422; and the clutch sleeve 41 is driven into the disengaged state by the elastic telescopic electromagnet 421.

[0043] In the absence of external force, the return spring 422 can automatically push the clutch sleeve 41 toward the engaged state. The elastic telescopic electromagnet 421 has a telescopic drive. When it is extended, it can provide sufficient thrust to the clutch sleeve 41. This thrust is sufficient to overcome the elastic force of the return spring 422 and push the clutch sleeve 41 from the engaged state to the disengaged state.

[0044] The clutch driver 42 of this embodiment achieves rapid and precise control of the clutch sleeve 41, enabling the clutch 4 to switch between the engaged and disengaged states in a short period of time. Furthermore, this structure is simple and easy to control, requiring only the on / off control of the elastically retractable battery iron.

[0045] In one embodiment, referring to Figure 3 The elastic telescopic electromagnet 421 includes a telescopic iron core, and the end of the telescopic iron core is connected to a wedge-shaped push block 4211. When the elastic telescopic electromagnet 421 is powered on, the telescopic iron core retracts, the wedge-shaped push block 4211 moves away from the clutch sleeve 41, and the return spring 422 drives the clutch sleeve 41 into the engaged state; when the elastic telescopic electromagnet is powered off, the telescopic iron core extends, and the wedge-shaped push block 4211 approaches and pushes the clutch sleeve 41 away from the blower 3 and into the disengaged state.

[0046] Based on the arrangement of the wedge-shaped push block 4211 , the elastic telescopic electromagnet 421 is allowed to be arranged vertically on one side of the clutch sleeve 41 , thereby avoiding the problem of the elastic telescopic electromagnet 421 interfering with the axial sliding of the clutch sleeve 41 .

[0047] In one embodiment, the washing drum 1 includes an outer drum 11 and an inner drum 12 , and the first output shaft 21 passes through the outer drum 11 and is transmission-connected to the inner drum 12 to drive the inner drum 12 to rotate relative to the outer drum 11 .

[0048] The outer drum 11 serves as a fixed part, providing stable support and protection for the inner drum 12; while the inner drum 12 serves as a rotating part, which drives the clothes to roll and rub in the water through its rotation, thereby achieving the purpose of washing.

[0049] In one embodiment, an electric heater and an air supply duct are further included. The electric heater and the blower 3 are connected, and the electric heater and the outer cylinder 11 are connected respectively through the air supply duct.

[0050] Specifically, the electric heater is cleverly set at a certain position of the washing machine, and is connected to the blower 3 through an air supply duct. In this way, when the blower 3 is running, it can suck in air and transport it to the electric heater through the air supply duct for heating. The heated hot air is transported to the outer drum 11 area of ​​the washing drum 1 through the air supply duct, thereby providing the required drying function for the clothes.
