Description

Technical Field

[0001] This utility model relates to the field of clothing processing technology, and in particular to a clothing drying device. Background Technology

[0002] Clothes drying equipment is a widely used household appliance that can quickly dry clothes. Existing clothes drying equipment uses a power unit consisting of a motor and belt to simultaneously drive the impeller of the drum and fan. Under the airflow provided by the fan, hot, dry air enters the drum from the rear. Since the drum's speed is set after the drying equipment starts, the impeller speed cannot be adjusted. Therefore, it's impossible to adjust the airflow to adapt to different load conditions and reduce damage to clothes. Furthermore, it's also impossible to ensure drying efficiency by adjusting the airflow to accommodate varying degrees of heat dissipation due to differences in ambient temperature.

[0051] The following is based on Figures 1 to 11 This invention provides a detailed description of the clothing drying equipment.

[0052] In this embodiment, such as Figures 1 to 8 As shown, the clothes drying equipment 100 includes a drum 1, a first motor 3, a fan 8, and a housing 5. The drum 1 is used to hold clothes, the first motor 3 is used to drive the drum 1 to rotate, the fan 8 includes a second motor 81 for generating rotational driving force, and the housing 5 includes a vertical mounting member 523, on which the fan 8 is mounted. In this design, the drum 1 and the fan 8 are driven by independent motors. By adjusting the speed of the second motor 81, the airflow of the fan 8 can be adjusted to adapt to different drum load conditions, reducing damage to clothes. Furthermore, to address differences in the degree of heat dissipation due to ambient temperature variations, the airflow can be adjusted to ensure drying efficiency. In addition, when there are fewer clothes, the airflow can be reduced to lower the noise generated by the fan.

[0053] It should be understood that "vertical mounting component 523" in this document refers to a mounting component extending along the vertical direction of the clothes drying equipment 100, wherein the vertical direction refers to the direction intersecting with the horizontal direction, including the vertical direction and the direction forming an angle with the vertical direction.

[0054] In one embodiment, the assembly method of the fan 8 and the vertical mounting component 523 includes fastener (such as screws) connection or snap-fit, which makes assembly quick.

[0055] In one implementation, such as Figure 1 , Figure 5 and Figure 7 As shown, the housing 5 includes a rear outer shell 51, a base 52, a front shell 53, a left side plate 54, a right side plate 55, and a top plate 56. The front shell 53 has a clothes loading port 531, which is opposite to the opening of the drum 1. The drum 1 is located in the housing 5, and the base 52 is located below the drum 1. The base 52 has a second air duct 62, and the heat exchange component 9 of the clothes drying equipment 100 is located in the second air duct 62. The rear side plate of the base 52 forms a vertical mounting member 523, on which the fan 8 is mounted for easy assembly. Specifically, as shown... Figure 7 and Figure 9 As shown, the heat exchange assembly 9 includes an evaporator 91, a condenser 92 and a compressor 93. The evaporator 91 and the condenser 92 are arranged sequentially along the airflow direction. The second air duct 62 is used to form high-temperature dry air.

[0056] Furthermore, such as Figure 1 and Figure 4As shown, the outer wall of the vertical mounting component 523 is provided with a first recess 5231 and an air inlet 5232. The fan 8 is embedded in the first recess 5231, preventing the fan 8 from protruding beyond the rear side plate of the base 52 or preventing the fan 8 from protruding excessively beyond the rear side plate of the base 52, thereby reducing the space occupied by the fan 8 behind the base 52. Figure 2 , Figure 4 and Figure 10 As shown, the air inlet 5232 is used to connect the second air duct 62 and the airflow inlet 83 of the fan 8. Under the airflow provided by the fan 8, the high-temperature dry air in the second air duct 62 enters the fan 8 through the airflow inlet 83.

[0057] Furthermore, such as Figure 4 As shown, the outer wall of the vertical mounting component 523 is provided with a second recess 5233, which is located in the first recess 5231. The depth of the second recess 5233 is greater than the depth of the first recess 5231, and the air inlet 5232 is located in the second recess 5233. Figure 2 and Figure 3 As shown, the fan 8 includes an impeller 82 and an impeller cover 84. The impeller cover 84 is connected to a vertical mounting member 523, and the impeller 82 is mounted on the impeller cover 84. A second motor 81 is connected to the impeller 82 and is used to drive the impeller 82 to rotate. Figure 2 and Figure 4 As shown, an air guide groove 85 is formed between the outer peripheral wall of the impeller 82 and the impeller cover 84. The air guide groove 85 and the second recess 5233 are positioned opposite each other and together form the fan duct. In this design, the groove wall of the air guide groove 85 and the surface of the second recess 5233 together form a volute structure. The arrangement of the air guide groove 85 helps to reduce the weight of the fan 8 and also helps to reduce the space required for the second recess 5233 to accommodate the fan 8, that is, it helps to reduce the depth of the second recess 5233, thereby reducing the space occupied by the second duct 62. Of course, the structure of the fan 8 is not limited to this. The fan 8 can also be configured with a volute structure to form the fan duct.

[0058] Furthermore, such as Figures 2 to 5 As shown, the air guide slot 85 is provided with a first opening 851. The first opening 851 and the surface of the second recess 5233 together form the airflow outlet of the fan 8. The second recess 5233 is provided with a second opening 52331. The second opening 52331 is located directly above the first opening 851. The first opening 851 and the second opening 52331 are connected to guide the airflow in the second air duct 62.

[0059] In one embodiment, the fan 8 is provided with a sealing structure 86, which includes, but is not limited to, foam sponge or rubber parts. The sealing structure 86 is used to seal the fan duct to prevent airflow in the fan duct from leaking outward.

[0060] Furthermore, such as Figure 2 and Figure 3 As shown, the impeller cover 84 includes a cover body 841 and a sidewall 842 formed on the outer periphery of the cover body 841. An air guide slot 85 is formed between the sidewall 842 and the impeller 82. The end of the sidewall 842 extends away from the impeller 82 and forms a first abutment arm 843. Figures 2 to 6 As shown, the first abutting arm 843 is provided with a plurality of first mounting holes 8431, and the first recess 5231 is provided with a plurality of second mounting holes 52311. The first mounting holes 8431 and the second mounting holes 52311 are arranged in a one-to-one correspondence. The first abutting arm 843 abuts against the first recess 5231, and fasteners (such as screws) pass through the first mounting holes 8431 and the second mounting holes 52311 to fasten the impeller cover 84 to the vertical mounting member 523. In addition, as Figure 2 , Figure 3 and Figure 6 As shown, the first abutting arm 843 extends away from the vertical mounting member 523 at the second opening 52331 and forms the second abutting arm 844. This increases the size of the second opening 52331 and also increases the contact area between the impeller cover 84 and the first recess 5231.

[0061] like Figure 2 and Figure 3 As shown, the sealing structure 86 includes a first sealing element 861 and a second sealing element 862. The first sealing element 861 is installed on the inner wall of the side wall 842 and extends along the side wall 842. The second sealing element 862 is installed at the first opening 851 of the air guide groove 85. The first sealing element 861 and the second sealing element 862 cooperate to form a seal around the air guide groove 85. Further, the first sealing element 861 is located in the air guide groove 85 and partially extends to the outside of the air guide groove 85. The second sealing element 862 may be located in the first opening 851 and partially extends to the outside of the first opening 851, or the second sealing element 862 may be completely located outside the first opening 851. When the impeller cover 84 and the vertical mounting member 523 are assembled, the first sealing element 861 and the second sealing element 862 are compressed and deformed to form a sealing structure.

[0062] Furthermore, such as Figure 2 , Figure 4 and Figure 6As shown, the first abutting arm 843 is provided with a positioning hole 8432, and the first recess 5231 is provided with a positioning post 52312. When assembling the fan 8, the positioning hole 8432 is first aligned with the positioning post 52312, and then the impeller cover 84 is inserted into the first recess 5231. The positioning hole 8432 and the positioning post 52312 cooperate to provide positioning assistance for the installation position of the fan 8, thereby reducing the difficulty of operation. Furthermore, in order to improve the positioning accuracy, there are at least two positioning holes 8432, and the positioning post 52312 is set in a one-to-one correspondence with the positioning hole 8432.

[0063] In one implementation, such as Figure 4 and Figure 7 As 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 vertical mounting member 523 is formed by the rear end of the cover plate 521 and the rear side wall of the base 522. The second opening 52331 is provided on the cover plate 521.

[0064] In one implementation, such as Figure 1 , Figure 4 and Figure 7 As shown, the clothes drying equipment 100 also includes a fan hood 2, which is located behind the drum 1. The fan hood 2 is used to guide the high-temperature drying air in the clothes drying equipment 100 into the drum 1. The fan hood 2 is located above the vertical mounting member 523, and the air outlet of the fan 8 is connected to the air inlet channel 2121 of the fan hood 2. Specifically, as shown... Figure 7 , Figure 8 and Figure 10 As shown, the drum 1 includes a drum cavity 11 for holding clothes. The bottom 12 of the drum 1 is provided with an air inlet 121. The high-temperature dry air in the second air duct 62 is introduced into the air hood 2 by the fan 8, and then introduced into the drum cavity 11 through the air inlet 121 to dry the clothes.

[0065] Furthermore, such as Figure 7 and Figure 8As shown, the rear outer shell 51 is a sheet metal structure. The air hood 2 is located between the rear outer shell 51 and the bottom 12 of the drum 1. The air hood 2 and the outer wall of the bottom 12 form a first air duct 61, which is connected to the air inlet channel 2121. A third air duct 63 is formed between the front wall of the drum 1 and the front shell 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. The first air duct 61 is used to introduce the high-temperature dry air in the second air duct 62 into the drum cavity 11 through the air inlet 121. In this solution, the air hood 2 is placed between the rear outer shell 51 and the bottom 12 of the drum to prevent the high-temperature dry air generated in the clothes drying equipment 100 from directly contacting the rear outer shell 51 during the process of entering the drum cavity 11, thus avoiding heat loss and shortening the drying time. Furthermore, the rear outer casing 51 covers the fan shroud 2, which reduces heat loss in the first air duct 61 and lowers the noise generated when the clothes drying equipment 100 is operating. The rear outer casing 51 covers the outside of the fan 8 and serves as the rear surface contour of the clothes drying equipment 100, improving its aesthetic appearance.

[0066] When the clothes dryer 100 turns on the drying mode, if Figures 5 to 10 As shown, the second motor 81 drives the impeller 82 to rotate. The airflow in the second air duct 62 enters the fan 8 and then flows into the first air duct 61. During this process, the compressor 93 works, causing the condenser 92 to heat the air to form high-temperature dry air. The high-temperature dry air flows into the first air duct 61 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.

[0067] 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.

[0068] In one implementation, such as Figure 4 and Figure 7 As shown, the hood 2 includes a supporting body 21 and a housing structure 22. The supporting body 21 is supported on the base 52, and the housing structure 22 is connected to the supporting body 21. A first air duct 61 is formed between the housing structure 22 and the outer wall of the roller 1. The supporting body 21 includes a reinforcing structure 211 and an air inlet structure 212. The air inlet channel 2121 is provided on the air inlet structure 212. The reinforcing structure 211 is used to increase the contact area between the supporting body 21 and the base 52, thereby improving the load capacity of the hood 2 and extending its service life.

[0069] Furthermore, such as Figure 4 and Figure 7 As shown, since 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. The space between the drum 1 and the rear outer shell 51 is limited. Therefore, the reinforcing structure 211 and the air inlet structure 212 are sequentially distributed along the width direction of the hood 2 to reduce the space occupied by the hood 2 in the front-back direction of the clothes drying equipment 100. The bottom surfaces of the reinforcing structure 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 completely or as much as possible abuts 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.

[0070] Furthermore, such as Figure 4 As shown, 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.

[0071] Furthermore, such as Figure 4 As shown, 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 abutting surface to extend the dimension of the second abutting surface in the width direction of the hood 2, so that the length L2 of the second abutting surface is equal to the maximum width of the top surface of the base 52.

[0072] In one embodiment, the support body 21 and the base 52 are connected by a first positioning protrusion and a first positioning groove (not shown in the figure) to achieve positioning pre-assembly. Furthermore, the support body 21 and the base 52 are connected by fasteners or buckles to further improve the assembly firmness of the fan cover 2 and the base 52.

[0073] In one embodiment, the reinforcing structure 211 and the base 52 are connected to the limiting post through a limiting groove to restrict the movement of the wind shield 2.

[0074] In one embodiment, the cover plate 521 and the base 522 are connected by a second positioning protrusion and a second positioning groove (not shown in the figure) to achieve positioning pre-installation, and then connected by fasteners or buckles.

[0075] In one implementation, such as Figure 7 and Figure 8 As shown, the first motor 3 includes a drive shaft 31, which is coaxially connected to the roller 1. The drive shaft 31 and the roller 1 can be directly coaxially connected, or they can be coaxially connected using an adapter (such as an adapter block). Directly driving the roller 1 with the first motor 3 eliminates the need for a belt structure, reduces space occupation, saves energy and reduces noise, and provides a more stable, efficient, and longer service life.

[0076] Furthermore, such as Figure 8 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 high-temperature drying air 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 conducive to transmission stability.

[0077] In one implementation, such as Figure 10 and Figure 11As 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 (not shown in the figure) 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.

[0078] 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.

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.
