[0067] In this utility model, "front," "rear," "left," "right," "up," and "down" all refer to... Figure 1 , Figure 9 and Figure 13 The markings in the text shall prevail.

[0068] The following is based on Figures 1 to 13 This invention provides a detailed description of the clothing drying equipment.

[0069] In this embodiment, such as Figures 1 to 3 , Figure 9 and Figure 10 As shown, the clothes drying equipment 100 includes a drum 1, a fan hood 2, a drive shaft 31, and a housing 5. The housing 5 includes a base 52. The drum 1 includes a drum cavity 11 for accommodating clothes. The bottom 12 of the drum 1 is provided with an air inlet 121. The fan hood 2 is located behind the drum 1 and is used to introduce high-temperature dry air from the clothes drying equipment 100 into the drum cavity 11 through the air inlet 121 to dry the clothes in the drum cavity 11. The drive shaft 31 is used to drive the drum 1 to rotate and is mounted on the fan hood 2. The fan hood 2 includes a support body 21, which is supported on the base 52. The support body 21 includes a reinforcing structure 211 and an air inlet structure 212. The air inlet structure 212 is provided with an air inlet channel 2121. The high-temperature dry air generated in the clothes drying equipment 100 enters the fan hood 2 through the air inlet channel 2121. The reinforcing structure 211 is used to increase the contact area between the support body 21 and the base 52.

[0070] In the above technical solution, the wind cover 2 has the two functions of forming an air duct and supporting the rotation of the roller 1. Furthermore, by adding a reinforcing structure 211 to the support body 21, the structural strength of the wind cover 2 is improved, thereby increasing the load capacity of the wind cover 2 and extending its service life.

[0071] In one implementation, such as Figure 1 and Figure 9 As shown, the housing 5 includes a rear outer shell 51, which is a sheet metal structure. A fan hood 2 is located between the rear outer shell 51 and the bottom 12 of the drum 1. A first air duct 61 is formed between the fan hood 2 and the outer wall of the drum 1. The first air duct 61 communicates with the air inlet channel 2121. The first air duct 61 is used to guide the high-temperature drying air in the clothes drying equipment 100 into the drum cavity 11 through the air inlet 121. In this design, the fan hood 2 is positioned between the rear outer shell 51 and the bottom 12 of the drum to prevent the high-temperature drying air generated in the clothes drying equipment 100 from directly contacting the rear outer shell 51 during its entry into the drum cavity 11, thus avoiding heat loss and shortening the drying time. Furthermore, the rear outer shell 51 covers the fan hood 2, reducing heat loss in the first air duct 61 and lowering the noise generated during operation of the clothes drying equipment 100.

[0072] In one implementation, such as Figure 1 and Figure 9As shown, the shroud 2 also includes a cover structure 22, which is connected to the support body 21. A first air duct 61 is formed between the cover structure 22 and the outer wall of the roller 1. The drive shaft 31 is installed on the cover structure 22. By limiting the structural design of the cover structure 22, the structure, shape and size of the first air duct 61 can be limited.

[0073] Furthermore, such as Figure 1 As shown, the cover structure 22 is located directly above the support body 21, which helps the support body 21 to stably support the cover structure 22.

[0074] Furthermore, such as Figure 1 As shown, the supporting body 21 and the cover structure 22 are integrally formed, which simplifies the assembly process.

[0075] In one implementation, such as Figure 1 and Figure 9 As shown, the hood 2 is located behind the drum 1. The width of the hood 2 extends along the left-right direction of the clothes drying equipment 100, and the thickness of the hood 2 extends along the front-back direction of the clothes drying equipment 100. Since the space between the drum 1 and the rear outer shell 51 is limited, when there is only one reinforcing structure 211, the reinforcing structure 211 and the air inlet structure 212 are sequentially distributed along the width direction of the hood 2. When there are two reinforcing structures 211, the dimensions of the two reinforcing structures 211 can be equal or unequal, and their shapes can be the same or different. One reinforcing structure 211, the air inlet structure 212, and the other reinforcing structure 212 are sequentially distributed along the width direction of the hood 2, reducing the space occupied by the hood 2 in the front-back direction of the clothes drying equipment 100. Figures 1 to 3 As shown, the bottom surfaces of all the reinforcing structures 211 and the air inlet structure 212 form a first contact surface 213, and the top surface of the base 52 forms a second contact surface. The first contact surface 213 abuts downward against the second contact surface. That is, the bottom surface of the support body 21 abuts completely or as much as possible against the top surface of the base 52. By increasing the contact area between the support body 21 and the base 52, the stability of the support performance of the support body 21 is improved.

[0076] Furthermore, the length of the first contact surface 213 in the width direction of the wind cover 2 is L1, the length of the second contact surface in the width direction of the wind cover 2 is L2, and the maximum width of the top surface of the base 52 is equal to L2, and L1 is equal to L2, so as to ensure that the support body 21 can stably support the rotation of the roller 1.

[0077] In one implementation, such as Figure 1 , Figure 4 and Figure 9As shown, the base 52 includes a cover plate 521 and a base 522. The cover plate 521 is sealed to the top of the base 522, and the two together form a second air duct 62. The width of the rear end of the cover plate 521 is smaller than the width of the rear end of the base 522. The rear end of the cover plate 521 has a first top surface 5211, and the rear end of the base 522 has a second top surface 5221. The first top surface 5211 and the second top surface 5221 are distributed sequentially in the width direction of the hood 2. The first top surface 5211 and the second top surface 5221 together form a second abutment surface to extend the dimension of the second abutment surface in the width direction of the hood 2, so that the length L2 of the second abutment surface is equal to the maximum width of the top surface of the base 52.

[0078] In one embodiment, the maximum dimension of the cover structure 22 in the width direction of the wind cover 2 is L3, and the length of the first contact surface 213 in the width direction of the wind cover 2 is L1, where L1 is greater than L3. Thus, the wind cover 2 generally presents a structure that is smaller at the top and larger at the bottom, which facilitates the improvement of the overall support strength and stability of the wind cover 2.

[0079] Furthermore, the circumferential outer wall of the cover structure 22 is in the shape of a superior arc, and the diameter R of the superior arc is equal to L3. In this way, the wind cover 2 roughly presents a stable triangular structure with a smaller top and a larger bottom, which further improves the overall support strength and stability of the wind cover 2.

[0080] In one embodiment, the support body 21 and the base 52 are connected by a positioning protrusion and a positioning groove to achieve pre-positioning. Specifically, as shown... Figure 4 and Figure 5 As shown, the bottom wall of the support body 21 is provided with a first positioning groove 214, and the top wall of the cover plate 521 is provided with a first positioning protrusion 5212. When the fan cover 2 is installed on the base 52, the first positioning groove 214 and the first positioning protrusion 5212 are aligned and inserted, making the operation convenient. Furthermore, a first sealing element 72 (such as a sealing sponge or rubber strip) is provided in the first positioning groove 214. The first sealing element 72 is sandwiched between the groove wall of the first positioning groove 214 and the first positioning protrusion 5212 to achieve a sealed connection. Of course, a positioning protrusion can also be provided on the support body 21, and a matching positioning groove can be provided on the base 52.

[0081] In one embodiment, the reinforcing structure 211 and the base 52 are interlocked via a limiting post and a limiting groove. This allows the shroud 2 to move relative to the base 52 in the insertion or removal direction, but restricts its movement in other directions, thus improving the stability of the assembly between the shroud 2 and the base 52. Specifically, the reinforcing structure 211 has a limiting groove 2113, and the top wall of the base 52 has a limiting post 5216. The size of the limiting post 5216 is larger than the size of the first positioning protrusion 5212. When the shroud 2 is installed on the base 52, the limiting post 5216 is inserted upwards into the limiting groove 2113 to restrict the horizontal movement of the shroud 2.

[0082] Furthermore, there are two reinforcing structures 211, located on the left and right sides of the air inlet structure 212 respectively. Each reinforcing structure 211 is provided with a limiting groove 2113 to be inserted into the base 52 to ensure the stability of the assembly between the shroud 2 and the base 52. Even further, if the contact area between one reinforcing structure 211 and the base 52 is larger than that between the other reinforcing structure 211 and the base 52, the reinforcing structure 211 with the larger contact area can be provided with multiple limiting grooves 2113 to be inserted into multiple limiting posts 5216 of the base 52.

[0083] In one embodiment, the support body 21 and the base 52 are connected by fasteners or snap-fits to further improve the assembly firmness of the fan cover 2 and the base 52. Specifically, as shown... Figure 6 As shown, the support body 21 has a first mounting hole 215, and the base 52 has a second mounting hole 5213. Screws (not shown) are used to engage with the first mounting hole 215 and the second mounting hole 5213 for fastening. Furthermore, the shroud 2 is also connected to the rear outer shell 51 to reinforce the shroud 2. It should be understood that if the support body 21 abuts against the cover plate 521 and the base 522 respectively, the support body 21 is connected to the cover plate 521 and the base 522 respectively to improve the assembly firmness of the shroud 2.

[0084] In one implementation, such as Figure 7 and Figure 8As shown, the cover plate 521 and the base 522 are pre-installed by interlocking the positioning protrusion and positioning groove, and then connected by fasteners or snap-fits. Specifically, the cover plate 521 has a second positioning groove 5214 and a third mounting hole 5215, and the base 522 has a second positioning protrusion 5222 and a fourth mounting hole 5223. When assembling the cover plate 521 and the base 522, the second positioning groove 5214 and the second positioning protrusion 5222 are aligned and interlocked, and then screws (not shown in the figure) are passed through the third mounting hole 5215 and the fourth mounting hole 5223 to achieve fastening. Further, a third sealing element 74 (such as a sealing sponge or rubber strip) is provided in the second positioning groove 5214. The third sealing element 74 is sandwiched between the groove wall of the second positioning groove 5214 and the second positioning protrusion 5222 to achieve sealing.

[0085] In one implementation, such as Figures 1 to 3 As shown, the reinforcing structure 211 includes a plate 2111 and reinforcing ribs 2112. The reinforcing ribs 2112 are provided on the surface wall of the plate 2111 and are in a grid pattern. In this way, the reinforcing structure 211 can be reduced in weight while ensuring the structural strength of the reinforcing structure 211.

[0086] Furthermore, the circumferential outer wall of the shell structure 22 is circular or arc-shaped. The reinforcing ribs 2112 include multiple straight ribs 21121 and multiple arc-shaped ribs 21122. The straight ribs 21121 extend vertically, and the arc-shaped ribs 21122 extend along the circumferential outer wall of the shell structure 22. The multiple straight ribs 21121 and the multiple arc-shaped ribs 21122 intersect to form a grid-like reinforcing rib network 2112. In this design, by optimizing the rib shape of the reinforcing ribs 2112, the strength and support capacity of the reinforced structure 211 are further improved.

[0087] In one implementation, such as Figure 9 , Figure 11 and Figure 13 As shown, the clothes drying equipment 100 includes a fan 8, an evaporator 91, a condenser 92, and a compressor 93. The fan 8 includes a second motor 81 and an impeller 82. The evaporator 91, condenser 92, and compressor 93 are all located in a second air duct 62. The evaporator 91 and condenser 92 are arranged sequentially along the airflow direction. The second air duct 62 is used to form a hot airflow (high-temperature dry air). The second air duct 62, the air inlet channel 2121, and the first air duct 61 are connected sequentially. The support body 21 is supported by the cover plate 521. The base 52 is designed as a split structure to facilitate the assembly of the evaporator 91, condenser 92, and compressor 93 in the second air duct 62.

[0088] like Figure 9As shown, the housing 5 of the clothes drying equipment 100 also includes a front housing 53, which has a clothes inlet 531. When using the clothes drying equipment 100, the user puts clothes into the drum 1 through the clothes inlet 531. The front housing 53 and the rear housing 51 are respectively connected to the base 52 by fasteners. The front part of the drum 1 is rotatably connected to the front housing 53, and the rear part of the drum 1 is rotatably connected to the rear housing 51. The drum 1 is supported by the front housing 53 and the rear housing 51. Of course, the housing 5 also includes side plates and a top plate, the structure of which can refer to any existing clothes dryer and will not be described in detail here. A third air duct 63 is formed between the front wall of the drum 1 and the front housing 53. The second air duct 62, the first air duct 61, the drum cavity 11, the third air duct 63 and the second air duct 62 are connected in sequence to form a circulating airflow channel.

[0089] When the clothes dryer 100 turns on the drying mode, if Figures 9 to 13 As shown, when the fan 8 starts, the airflow in the second air duct 62 flows toward the first air duct 61. During this process, the compressor 93 operates, causing the condenser 92 to heat the air, forming high-temperature dry air. The high-temperature dry air flows into the first air duct 61 under the power of the fan 8, and then enters the drum cavity 11 of the drum 1 through the air inlet 121, absorbing the moisture in the clothes and forming humid and hot air. The humid and hot air flows through the third air duct 63 and the second air duct 62 in sequence. In the second air duct 62, the humid and hot air is first cooled by the evaporator 91 to form low-temperature dry air, and then heated by the condenser 92 to form high-temperature dry air. The high-temperature dry air then enters the drum cavity 11 of the drum 1 in sequence through the first air duct 61 and the air inlet 121. Through the circulation of airflow, the clothes are dried.

[0090] It should be understood that the working principles of compressor 93, evaporator 91, and condenser 92 can be referenced from the working principles of corresponding structures in any existing clothes drying equipment. Here, the corresponding heat release and heat absorption principles are briefly explained. Specifically, compressor 93 compresses low-temperature, low-pressure gas into high-temperature, high-pressure gas. The high-temperature, high-pressure gas is transformed into a high-temperature, medium-pressure gas-liquid mixture (working fluid) through a throttling device. The working fluid flows between compressor 93, evaporator 91, and condenser 92. The working fluid first flows through condenser 92, where it changes from gas to liquid and releases heat to the surroundings, so that condenser 92 heats the low-temperature dry air into high-temperature dry air. Then, the working fluid flows through evaporator 91, where it changes from liquid to gas and absorbs heat from the surroundings, so that evaporator 91 cools the humid, hot air into low-temperature dry air.

[0091] In one implementation, such as Figure 10As shown, the clothes drying equipment 100 also includes a first motor 3. The rotor 32 of the first motor 3 is coaxially connected to the drive shaft 31. The drive shaft 31 and the drum 1 can be directly coaxially connected, or they can be coaxially connected by means of an adapter (such as an adapter block). By directly driving the drum 1 to rotate through the first motor 3, the belt structure is eliminated, reducing space occupation and achieving energy saving and noise reduction. The drive is more stable, more efficient, and has a longer service life.

[0092] In one implementation, such as Figure 3 and Figure 10 As shown, the clothes drying equipment 100 also includes a bearing assembly 4, which includes a bearing 41 and a bearing housing 42. The bearing housing 42 is a sheet metal structure, and the fan shroud 2 is a plastic structure. The fan shroud 2 has a mounting hole 221, and the bearing housing 42 is installed in the mounting hole 221. The drive shaft 31 is installed in the bearing housing 42 via the bearing 41. In this design, the fan shroud 2 is a plastic structure, which has good heat insulation performance. During the process of the fan shroud 2 introducing hot airflow into the drum cavity 11, it can reduce heat loss and improve drying efficiency. The bearing housing 42 is a sheet metal structure with high structural strength. The load is directly borne by the bearing housing 42, which avoids deformation of the mounting hole 221 of the fan shroud 2 due to long-term concentrated force, thus preventing a decrease in the stability of the transmission between the first motor 3 and the drum 1, and is beneficial to transmission stability.

[0093] In one implementation, such as Figure 11 and Figure 12 As shown, the casing structure 22 has a first recess 223 and a second recess 224 on the side facing the roller 1. The first recess 223 surrounds the second recess 224, and the depth of the first recess 223 is greater than the depth of the second recess 224. The first recess 223 and the outer wall of the roller 1 form a first air guide channel 611, and the second recess 224 and the outer wall of the roller 1 form a second air guide channel 612. The first air guide channel 611 and the second air guide channel 612 are connected to form a first air duct 61. The first recess 223 has an opening on the side facing the air inlet channel 2121, and the first air guide channel 611 is connected to the air inlet channel 2121 through the opening.

[0094] During the drying process, the high-temperature dry air in the second air duct 62 enters the first air guide duct 611 through the air inlet duct 2121. Part of the airflow in the first air guide duct 611 flows along the first air guide duct 611 first, then flows to the second air guide duct 612 and enters the drum 1. Another part of the airflow enters the first air guide duct 611 and then directly enters the second air guide duct 612 before entering the drum 1. In this design, by improving the structure of the cover structure 22, it is beneficial for the airflow in the first air duct 61 to flow evenly into the drum 1, thus improving the drying effect.

[0095] In one implementation, such as Figure 9 and Figure 12 As shown, since the roller 1 rotates relative to the shroud 2, there needs to be a gap between the roller 1 and the shroud 2 to avoid friction between them. However, the existence of this gap will cause the first air duct 61 to connect with the external space of the shroud 2. In this solution, in order to prevent the high-temperature dry air in the first air duct 61 from leaking out from the gap between the shroud 2 and the bottom of the cylinder 12, a second sealing element 73 is provided between the shroud 2 and the bottom of the cylinder 12. The second sealing element 73 is connected to the front side wall of the shroud 2. The second sealing element 73 and the shroud 2 are both fixed. The second sealing element 73 is used to seal the gap between the shroud 2 and the bottom of the cylinder 12 to avoid heat loss.

[0096] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this utility model that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this utility model and do not limit the scope of protection of this utility model patent.
