Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, specifically to a clothes drying machine motor compartment. Background Technology

[0002] The clothes drying rack uses a motor to drive a steel wire rope for unwinding and rewinding, and the tension of the wire rope causes the drying device to rotate. Currently, there are two main structural installation methods for the internal motor: the first is to directly fix the motor inside the clothes drying rack's outer casing with multiple bolts, without the need for a separate motor housing; the second is to first install the motor in a separate housing, and then fix that housing as a whole to the inside of the clothes drying rack's outer casing. The latter has advantages in terms of motor protection and installation flexibility, allowing the installation position to be flexibly adjusted according to the internal layout of the outer casing.

[0003] The currently used independent motor housing structure typically consists of two parts: the main housing and the cover, which are connected and fixed by multiple bolts. However, due to the limitations of the housing thickness and the design of the bolt thread holes, this type of structure often requires special design of the motor housing and increased material usage to ensure connection strength. This also makes the assembly process more complex, and increases the assembly time and difficulty accordingly. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a clothes drying machine motor compartment that adopts a quick-release structure for the motor compartment body and the compartment cover, which can eliminate the need for bolt connections, make assembly faster and more precise, and reduce the design difficulty of the motor compartment body and the compartment.

[0005] The technical solution of this utility model is to provide a clothes drying rack motor compartment with the following structure, including a motor compartment body and a compartment cover for accommodating a motor. The motor compartment body has a first connecting end on its inner wall at the opening position, and the compartment cover has an axially downward extending end at its bottom. The extending end has a second connecting end. The first connecting end consists of multiple first arc-shaped protrusions on the inner wall of the motor compartment body, and the second connecting end consists of multiple arc-shaped grooves on the outer wall of the extending end. In the locked state, each first arc-shaped protrusion is embedded in one of the arc-shaped grooves to achieve axial positioning. Simultaneously, the motor compartment body and the compartment cover have a circumferential locking structure.

[0006] The arc-shaped groove is formed by a third arc-shaped protrusion and a fourth arc-shaped protrusion provided on the extended end.

[0007] The first arc-shaped protrusions are located within the same circumference and are spaced apart. When the engine compartment cover is axially inserted into the motor compartment body, the fourth arc-shaped protrusion passes through the space between the two adjacent first arc-shaped protrusions. Then, the engine compartment cover and the motor compartment body are rotated relative to each other in the circumferential direction by an angle, so that the fourth arc-shaped protrusion rotates to the bottom of the first arc-shaped protrusion, and the top of the first arc-shaped protrusion abuts against the bottom of the third arc-shaped protrusion.

[0008] The engine compartment cover and the motor compartment body are provided with an insertion alignment structure. The bottom extension end of the engine compartment cover is divided into two sections. Each end of the extension end of each section is provided with a fourth arc-shaped protrusion. The alignment structure means that one of the fourth arc-shaped protrusions at one end of each section is provided with a notch along the height direction. The space between the two adjacent first arc-shaped protrusions is provided with a protrusion. The protrusion is provided on the inner side wall of the motor compartment body. When the engine compartment cover is axially inserted into the motor compartment body, the position of the notch is aligned with the position of the protrusion, and the two are axially inserted and pass through.

[0009] The circumferential locking structure of the motor compartment body and the compartment cover means that the body of the compartment cover is provided with an elastic piece, one end of which is a fixed end and fixed in the hole of the body of the compartment cover, and the other end is a free end with a limiting block at the bottom. After the compartment cover and the motor compartment body rotate relative to each other in the circumferential direction by an angle, the limiting block abuts against the side of one of the first arc-shaped protrusions and is circumferentially locked.

[0010] The limiting block protrudes from the bottom surface of the engine compartment cover, and the free end of the elastic sheet is elastic, swinging upward under the action of external force and automatically returning to its original position when the external force disappears.

[0011] With the above structure, this utility model has the following advantages: 1. Because the axial limiting of the motor housing cover and the motor housing body is achieved by each of the first arc-shaped protrusions embedded in one of the arc-shaped grooves in the locked state, and the rotating fastening structure ensures the connection strength of the two, while also eliminating the need for bolts and mounting bolts. 2. Furthermore, because the motor housing body and the motor housing cover are equipped with a circumferential locking structure, they are positioned after rotation to prevent relative rotation, further increasing the connection strength of the two. 3. Through the interlocking of multiple sets of protrusions vertically and horizontally, the axial and circumferential limiting is very firm, effectively withstanding the vibration and gravity of the motor during operation.

[0012] As an improvement, the arc-shaped groove is formed by a third arc-shaped protrusion and a fourth arc-shaped protrusion on the extension end, and is connected to the motor compartment body through the extension end that extends into the motor compartment body, without affecting the structure of the compartment cover itself.

[0013] As an improvement, the first arc-shaped protrusions are located within the same circumference and are spaced apart. When the engine compartment cover is axially inserted into the motor compartment body, the fourth arc-shaped protrusion passes through the space between the two adjacent first arc-shaped protrusions. Then, the engine compartment cover and the motor compartment body are rotated relative to each other by an angle in the circumference, so that the fourth arc-shaped protrusion rotates to the bottom of the first arc-shaped protrusion, and the top of the first arc-shaped protrusion abuts against the bottom of the third arc-shaped protrusion. This rotation locking structure is simple to operate and has good reliability.

[0014] As an improvement, the engine compartment cover and the motor compartment body are provided with an insertion alignment structure. The bottom extension end of the engine compartment cover is divided into two sections, and each end of the extension end of each section is provided with a fourth arc-shaped protrusion. The alignment structure means that one of the fourth arc-shaped protrusions at one end of the extension end of each section is provided with a notch along the height direction, and the space between the two adjacent first arc-shaped protrusions is provided with a protrusion. The protrusion is located on the inner side wall of the motor compartment body. When the engine compartment cover is axially inserted into the motor compartment body, the position of the notch is aligned with the position of the protrusion, and the two are axially inserted and pass through, which facilitates the operator's equipment and plays a role in preventing errors.

[0015] As an improvement, the motor housing body and the housing cover are provided with a circumferential locking structure, which means that the housing cover body is provided with an elastic sheet, one end of which is a fixed end and fixed in the hole of the housing cover body, and the other end is a free end with a limiting block at the bottom. After the housing cover and the motor housing body rotate relative to each other in the circumferential direction by an angle, the limiting block abuts against the side of one of the first arc-shaped protrusions and locks in the circumferential direction. This locking can be directly locked by external force in the assembly type, without the need for a switch light structure, and the operation is simple. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-8 As shown, the motor compartment of the clothes drying rack of this utility model includes a motor compartment body 1 for accommodating the motor and a compartment cover 2. The motor compartment body 1 has a first connecting end on its inner wall at the opening position, and the compartment cover 2 has an axially downward extending end 3 at its bottom. The extending end 3 has a second connecting end. The first connecting end consists of multiple first arc-shaped protrusions 4 on the inner wall of the motor compartment body 1, and the second connecting end consists of multiple arc-shaped grooves 5 on the outer wall of the extending end 3. In the locked state, the compartment cover 2 and the motor compartment body 1 are axially limited by each first arc-shaped protrusion 4 embedded in one of the arc-shaped grooves 5. Simultaneously, the motor compartment body 1 and the compartment cover 2 have a circumferential locking structure.

[0027] like Figure 2 As shown, the arc-shaped groove 5 is formed by a third arc-shaped protrusion 6 and a fourth arc-shaped protrusion 7 located on the extension end 3. The length of the fourth arc-shaped protrusion 7 is shorter than that of the third arc-shaped protrusion 6. The third arc-shaped protrusion 6 has a notch, which corresponds vertically to the position of the fourth arc-shaped protrusion 7.

[0028] The first arc-shaped protrusions 4 are located within the same circumference and are spaced apart. When the machine compartment cover 2 is axially inserted into the motor compartment body 1, the fourth arc-shaped protrusion 7 passes through the space between the two adjacent first arc-shaped protrusions 4. Then, the machine compartment cover 2 and the motor compartment body 1 are rotated relative to each other in the circumferential direction by an angle, so that the fourth arc-shaped protrusion 7 rotates to the bottom of the first arc-shaped protrusion 4, and the top of the first arc-shaped protrusion 4 abuts against the bottom of the third arc-shaped protrusion 6.

[0029] like Figure 4 and Figure 5As shown, the engine compartment cover 2 and the motor compartment body 1 are provided with an insertion alignment structure. The bottom extension end 3 of the engine compartment cover 2 is divided into two sections. Each end of the extension end 3 of each section is provided with a fourth arc-shaped protrusion 7. The alignment structure means that one of the fourth arc-shaped protrusions 7 at one end of each section is provided with a notch 8 along the height direction. The space between the two adjacent first arc-shaped protrusions 4 is provided with a protrusion 9. The protrusion 9 is provided on the inner side wall of the motor compartment body 1. When the engine compartment cover 2 is axially inserted into the motor compartment body 1, the position of the notch 8 is aligned with the position of the protrusion 9, and the two are axially inserted and pass through.

[0030] like Figure 3 and Figure 8 As shown, the circumferential locking structure provided by the motor housing body 1 and the housing cover 2 means that the body of the housing cover 2 is provided with an elastic piece 10. One end of the elastic piece 10 is a fixed end and is fixed in the hole of the body of the housing cover 2, and the other end is a free end and a limiting block 11 is provided at the bottom. After the housing cover 2 and the motor housing body 1 rotate relative to each other in the circumferential direction by an angle, the limiting block 11 abuts against the side of one of the first arc-shaped protrusions 4 and is circumferentially locked.

[0031] like Figure 3 As shown, the limiting block 11 protrudes from the bottom surface of the engine compartment cover 2, and the free end of the elastic sheet 10 is elastic, swinging upward under the action of external force and resetting itself when the external force disappears.

[0032] The assembly process of the motor compartment of this utility model is simple and quick, requiring only three steps: "alignment-insertion-rotation".

[0033] Step 1: Axial Alignment and Insertion: Align the extension end 3 of the housing cover 2 with the opening of the motor housing body 1. The extension end 3 is designed as two incomplete rings with a break in the middle, and one end of the fourth arc-shaped protrusion 7 has a notch 8 along the height direction. Simultaneously, a protrusion 9 is provided on the inner wall of the motor housing body 1 in the space between two adjacent first arc-shaped protrusions 4. During assembly, the fourth arc-shaped protrusion 7 with the notch 8 must be aligned with the position of the protrusion 9. Only after alignment can the protrusion 9 pass through the notch 8, allowing the extension end 3 to be smoothly inserted into the motor housing body 1. This is a design to prevent misassembly, ensuring the unique correctness of the assembly direction. After alignment, apply axial force to push the housing cover 2 into the motor housing body 1. At this time, the lower fourth arc-shaped protrusion 7 passes through the gap between the two adjacent first arc-shaped protrusions 4 until the top of the housing cover 2 is close to contact the end face of the motor housing body 1.

[0034] Step 2: Rotate circumferentially to the locking position: After the hood cover 2 is pushed to the top, hold the hood cover 2 and rotate it in one direction, usually clockwise, by a small angle, such as 15° to 30°. During rotation, the fourth arc-shaped protrusion 7 will rotate to the underside of the first arc-shaped protrusion 4, thereby creating an axial constraint and preventing the hood cover 2 from falling off. At the same time, the top of the first arc-shaped protrusion 4 will abut against the bottom of the higher third arc-shaped protrusion 6, completely restraining axial vertical movement and making the structure very stable.

[0035] Step 3: Circumferential Self-Locking: To ensure that the hood cover 2 will not automatically reverse or loosen under vibration or other conditions, this invention features a circumferential locking structure. This structure includes an elastic piece 10 mounted on the body of the hood cover 2. One end of the elastic piece 10 is fixed inside a hole in the hood cover 2, while the other end is free, with a limiting block 11 at its bottom. When the hood cover 2 rotates to a predetermined position, the limiting block 11 at the bottom of the elastic piece 10 will precisely abut against the side of a first arc-shaped protrusion 4. This lateral friction and resistance create a circumferential lock, preventing reverse rotation. For disassembly, simply use a tool such as a screwdriver to gently pry upwards the free end of the elastic piece 10, lifting the limiting block 11 and disengaging it from the first arc-shaped protrusion 4. The hood cover 2 can then be easily rotated in the reverse direction and removed. The elastic piece 10 is made of a material with good elasticity, such as spring steel or nylon, and can automatically reset itself after the external force is removed.
