Description

Technical Field

[0001] The invention belongs to the field of clothing processing equipment, and in particular, relates to a lifting rib for a clothes dryer and the clothes dryer. Background Art

[0002] Most current clothes dryers draw moisture from clothes by passing dry hot air into the dryer drum, and at the same time, the clothes are driven to move in the dryer drum as the dryer drum rotates, so as to increase the contact area between the clothes and the hot air and improve the drying efficiency. However, as the clothes rotate with the dryer drum, the clothes become entangled with each other, and the entangled clothes cannot fully contact the hot air, which affects the drying efficiency of the clothes. On the other hand, the entangled clothes will have wrinkles after being completely dried, which affects the appearance of the clothes and the user experience is poor.

[0003] In order to solve the problem of clothes entanglement during drying, in the prior art, stirring blades are arranged on the inner wall of the clothes drying drum to increase the stirring force of the clothes, and at the same time, the clothes drying drum is rotated alternately forward and reverse during the clothes drying process to reduce the entanglement of the clothes. However, the above method has limited effect on reducing the entanglement of clothes, and clothes entanglement still occurs from time to time. At the same time, the stirring blades directly rub against the clothes during the clothes drying process, which is easy to cause damage to the clothes. Therefore, how to effectively prevent clothes from getting entangled during the drying process has become a problem that needs to be solved urgently.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0051] Embodiment 1

[0052] like Figures 1 to 5 As shown, this embodiment provides a lifting rib 300 for a clothes dryer, including a shell 310 having a hollow chamber, and an air outlet 301 is provided on the shell 310. An air blowing pipeline assembly is arranged in the hollow chamber, and the air blowing pipeline assembly is connected to the shell 310, and air is blown to the outside of the shell 310 through the air outlet 301 on the shell 310.

[0053] In the above scheme, air can be blown to the outside of the lifting rib 300 through the air blowing pipe assembly inside the shell 310, which can blow away the clothes covering the lifting rib 300, thereby avoiding the clothes from getting tangled during the drying process to a certain extent, thereby improving the drying efficiency and reducing the occurrence of wrinkles on the clothes.

[0054] In a further embodiment of the present invention, the lifting rib 300 has a certain length, and a plurality of air outlets 301 are provided along the extension direction of the lifting rib 300. The air blowing pipeline 320 of the air blowing pipeline assembly is provided with a plurality of air outlets, and the plurality of air outlets are provided correspondingly to the plurality of air outlets 301 on the shell 310.

[0055] Preferably, the plurality of air outlet holes 301 are evenly distributed along the extension direction of the length of the lifting rib 300 .

[0056] In the above scheme, a plurality of air outlets 301 are arranged on the lifting rib 300 along the length direction, so that air can be blown in a larger range of the outer surface of the lifting rib 300, which has a better effect on blowing away the clothes. At the same time, a plurality of corresponding air outlets are arranged on the blowing pipeline 320, and one air outlet only provides blowing gas to one or several air outlets 301 around it, so that the intensity of the air blowing outward from each air outlet 301 can be more uniform.

[0057] In the preferred solution of this embodiment, the number of air outlets on the air blowing pipeline 320 is the same as the number of air outlet holes 301 on the housing 310, and the air outlets are arranged one by one with the air outlet holes 301. Each air outlet corresponds to an air outlet hole 301 to blow air outward, and the air flow intensity blown out by each air outlet hole 301 is more uniform.

[0058] In a further solution of this embodiment, a protruding air outlet portion 321 is provided on the side wall of the air blowing pipeline 320 , and the air outlet is arranged at the end of the air outlet portion 321 away from the side wall of the air blowing pipeline 320 , facing the air outlet hole 301 on the shell 310 .

[0059] Through the above-mentioned setting method, the blowing pipeline 320 maintains a certain distance from the inner wall of the shell 310, and at the same time, the air outlet can be closer to the air outlet hole 301, so as to avoid the gas blown out of the air outlet from being dispersed and weakened in strength during the process of flowing to the air outlet hole 301, thereby making the blown airflow stronger.

[0060] In this embodiment, the housing 310 includes a top wall 311 and a side wall 312 surrounding the top wall 311 to form a hollow chamber with one side open. The air outlet 301 is arranged on the top wall 311 to form an upwardly ejected airflow. When the lifting rib 300 of this embodiment is applied to a clothes dryer, it is installed on the wall of the clothes dryer drum, so that the air outlet 301 faces the central axis of the clothes dryer drum, and the effect of blowing the clothes is better and more obvious.

[0061] In a further solution of this embodiment, a nozzle 330 is sleeved on the air outlet portion 321 , and one end of the nozzle 330 away from the air blowing pipeline 320 is inserted into the air outlet hole 301 .

[0062] Specifically, the nozzle 330 includes a sleeve portion 331 sleeved on the gas outlet portion 321, and a first jet portion 332 and a second jet portion 333 extending from the sleeve portion 331 to the gas outlet hole 301. The second jet portion 333 is a conical structure extending toward the gas outlet hole 301 and having a gradually decreasing diameter. Jet holes are provided on both the first jet portion 332 and the second jet portion 333.

[0063] In the above scheme, by sleeve-fitting the nozzle 330 on the air outlet portion 321, the gas in the air blowing pipeline 320 is ejected through the nozzle 330, and a better air blowing effect can be achieved by designing the structure of the nozzle 330. The nozzle 330 is provided with a first air jet portion 332 and a second air jet portion 333 from bottom to top, and both are provided with air jet holes. The first air jet portion 332 can spray air toward the periphery of the nozzle 330, so that the gas fills the inside of the shell 310 and then blows out through the air outlet 301. The air jet hole on the second air jet portion 333 faces the air outlet 301, and directly sprays air toward the outside of the shell 310. The two airflows work together to achieve a better air blowing effect.

[0064] At the same time, the second jet part 333 is configured as a conical structure with a diameter gradually decreasing from bottom to top. The gas flowing from the first jet part 332 into the second jet part 333 has a higher pressure due to the reduction in the channel cross-sectional area, making the airflow intensity ejected from the second jet part 333 greater.

[0065] Preferably, in this embodiment, a first jet hole 335 is provided on the first jet part 332, and a second jet hole 336 is provided on the second jet part 333, and the diameter of the first jet hole 335 is greater than the diameter of the second jet hole 336. By limiting the diameters of the first jet hole 335 and the second jet hole 336, the strength of the airflow ejected through the second jet hole 336 is further increased, and the clothes covered on the lifting rib 300 can be blown away more effectively.

[0066] In a further solution of this embodiment, the air blowing pipeline assembly further includes a connecting plate 340 , on which a plurality of mounting holes are provided, and a plurality of nozzles 330 are inserted into the mounting holes in a one-to-one correspondence.

[0067] In this embodiment, the connecting plate 340 is connected to the housing 310 to achieve the connection between the blowing pipeline assembly and the housing 310. Figure 2 As shown, the connecting plate 340 is fixed inside the housing 310 by four screws 341 and connected to the top wall 311 of the housing 310 .

[0068] By setting the connecting plate 340, on the one hand, the relative positions of the nozzles 330 are fixed, reducing the possibility of deformation of the air outlet 321 on the air blowing pipeline 320, making the overall structure of the air blowing pipeline assembly more stable. On the other hand, by fixing the connecting plate 340 inside the shell 310, the air blowing pipeline 320 is indirectly connected to the shell 310, so that the air blowing pipeline 320 can be more stably fixed inside the lifting rib 300 without setting a complex installation structure on the air blowing pipeline 320. The structure inside the lifting rib 300 is simple and easy to implement.

[0069] In a preferred solution of this embodiment, a limiting portion 334 having an outer diameter larger than that of the sleeve portion 331 is provided between the sleeve portion 331 and the first jet portion 332 , and a surface of the limiting portion 334 facing the sleeve portion 331 abuts against a surface of one side of the connecting plate 340 .

[0070] More preferably, a fastener 337 is sleeved on the sleeve portion 331 , and the fastener 337 abuts against the surface of the other side of the connecting plate 340 .

[0071] In the above solution, the setting of the limiting portion 334 prevents the nozzle 330 from coming out of the mounting hole on the connecting plate 340, thereby preventing the connecting plate 340 from being separated from the air blowing pipeline 320, and failing to fix the air blowing pipeline 320. The fastener 337 is a fastening nut, and the fastener 337 and the limiting portion 334 and the two side surfaces of the connecting plate 340 are respectively abutted against each other, fixing the connecting plate 340 therebetween, making it less likely to loosen or move, and making the structure more stable.

[0072] In this embodiment, the right end of the blowing pipeline 320 is closed with a certain distance from the inner wall of the shell 310, and the left end passes through the shell 310, so as to be directly or indirectly connected to the gas source providing the blowing gas.

[0073] A through slot 313 for the air blowing pipeline 320 to extend out is formed on the side wall 312 at the right end of the housing 310 . The through slot 313 extends from the extending position of the air blowing pipeline 320 to the lower edge of the side wall 312 .

[0074] Through the above arrangement, the plurality of nozzles 330 can be first fixed on the connecting plate 340 in sequence, and then the connecting plate 340 can be fixed inside the housing 310 by means of screws 341. Afterwards, the air blowing pipeline 320 can be installed from the open opening of the housing 310 to the inside of the housing 310, so that each air outlet 321 is inserted into each nozzle 330 one by one. The air blowing pipeline 320 can have an opening of the through groove 313 and can be directly inserted into the through groove 313, without passing from the inside of the housing 310 to the outside, or being inserted from the outside of the housing 310 into the inside of the housing 310, so that the assembly steps are simple and easy to operate.

[0075] In this embodiment, by arranging an air blowing pipeline assembly inside the lifting rib 300, air can be blown from the inside of the lifting rib 300 to the outside, so as to blow away the clothes covered on the lifting rib 300. When the lifting rib 300 is installed in the clothes drying drum of the clothes dryer, air can be blown to the clothes during the clothes drying process to blow away the clothes, reduce the degree of entanglement of the clothes, thereby improving the drying efficiency, and at the same time, wrinkles on the surface of the clothes can be reduced, so that the clothes drying effect is better. The housing 310 is provided with a mounting portion 314 for connecting to the wall of the clothes drying drum to achieve the installation of the lifting rib 300, and the mounting portion 314 is preferably formed integrally with the housing 310.

[0076] By designing the structure of the air blowing pipeline assembly, a better air blowing effect can be achieved, and the air blowing pipeline assembly can be stably installed inside the housing 310, and is not easy to loosen and affect the air blowing effect. The assembly method of the lifting rib 300 is simple and easy to implement.

[0077] Embodiment 2

[0078] like Figures 6 to 10 As shown, this embodiment provides a dryer, including a dryer drum 100, and a rotating shaft 130 connected to the dryer drum 100 to drive the dryer drum 100 to rotate, and also includes an air blowing pipeline 320 with an air outlet located inside the dryer drum 100, and a fixed air supply pipeline (not shown in the figure).

[0079] The rotating shaft 130 is sleeved with a rotating joint 400, and the air supply pipeline is connected to the air blowing pipeline 320 through the rotating joint 400. One end of the rotating joint 400 is fixedly connected to the motor mounting device and connected to the air supply pipeline, and the other end is connected to the rotating shaft 130 and connected to the air blowing pipeline 320.

[0080] In this embodiment, the rotating shaft flange 131 at the left end of the rotating shaft 130 is fixedly connected to the bottom 110 of the clothes drying drum 100, and the motor mounting device includes a rear plate 200 fixedly arranged behind the bottom 110 of the clothes drying drum 100. The right end of the rotating shaft 130 passes through the rear plate 200 and is connected to the motor, and the clothes drying drum 100 is driven to rotate by the motor. The part of the rotating shaft 130 passing through the rear plate 200 is sleeved with a bearing 210, and the bearing 210 is fixed to the side of the rear plate 200 facing away from the clothes drying drum 100 through a bearing fixing cover 220 fixedly connected to the rear plate 200.

[0081] The rotary joint 400 is arranged between the rear plate 200 and the bottom 110 of the clothes drying drum 100, and includes a fixed end 410 and a rotating end 420 that are rotatably and sealedly connected, and the fixed end 410 is fixed to the rear plate 200 by screws. A gas inlet 411 for connecting to the gas supply pipeline is arranged on the side of the fixed end 410, and the rotating end 420 is connected to the rotating shaft 130 and rotates synchronously with the rotating shaft 130. A gas outlet 421 is arranged on the side of the rotating end 420, and the gas outlet 421 is connected to the blowing pipeline 320. The gas inlet 411 and the gas outlet 421 are connected through the gas channel inside the rotary joint 400, so as to realize the communication between the gas supply pipeline and the blowing pipeline 320.

[0082] In the above scheme, the air supply pipeline and the air blowing pipeline 320 are connected by setting a rotary joint 400. The fixed end 410 of the rotary joint 400 is fixedly set, and the rotating end 420 can rotate synchronously with the rotating shaft 130, thereby realizing the connection between the fixed air supply pipeline and the air blowing pipeline 320 that can rotate synchronously with the dryer 100, thereby realizing the purpose of transporting gas from the air supply pipeline to the air blowing pipeline 320 to blow air into the dryer 100. The structure is simple and easy to implement.

[0083] In a further solution of this embodiment, the blowing pipeline 320 includes a gas delivery section 510 extending from the rotary joint 400 to the periphery of the bottom 110 of the drying drum 100, and a blowing section 520 extending parallel to the central axis of the drying drum 100, and the blowing section 520 is arranged to pass through the bottom 110 of the drying drum 100.

[0084] In the above scheme, the blowing section 520 of the blowing pipeline 320 directly extends from the bottom 110 into the drying drum 100 to blow air into the drying drum 100, avoiding occupying the space around the drying drum 100 and effectively saving the internal space of the dryer.

[0085] Furthermore, the gas delivery section 510 includes a first delivery section 511 , a transition section 513 and a second delivery section 512 which are connected in sequence. The first delivery section 511 is connected to the rotary joint 400 , and the second delivery section 512 is connected to the blowing section 520 .

[0086] The first conveying section 511 and the second conveying section 512 are located behind the bottom 110 of the drying drum 100 and extend in the radial direction of the drying drum 100. The distance between the first conveying section 511 and the bottom 110 of the drying drum 100 is greater than the distance between the second conveying section 512 and the bottom 110 of the drying drum 100. The transition section 513 is arranged parallel to the central axis of the drying drum 100 and is connected to the first conveying section 511 and the second conveying section 512, respectively.

[0087] In the above scheme, the gas delivery section 510 includes a first delivery section 511, a transition section 513, and a second delivery section 512 which are arranged in sequence. Through the structural design of the gas delivery section 510, a certain distance is maintained between the portion close to the rotary joint 400 and the bottom 110 of the drying drum 100, and the portion away from the rotary joint 400 is closer to the bottom 110 of the drying drum 100. The first delivery section 511 has a larger interval with the bottom 110 of the drying drum 100, which can avoid the screws located near the center of the bottom 110 for connecting the rotating shaft flange 131. The second delivery section 512 is arranged close to the bottom 110 of the drying drum 100, so that the length of the blowing section 520 extending out of the bottom 110 of the drying drum 100 is as short as possible, avoiding the instability of the structure caused by the excessively long pipeline hanging outside the drying drum 100.

[0088] In a further solution of this embodiment, the clothes dryer further comprises the lifting rib 300 as described in the first embodiment, and the housing 310 of the lifting rib 300 is connected to the wall 120 of the clothes drying drum 100. The air blowing pipeline 320 of the air blowing pipeline assembly is partially disposed inside the housing 310, and partially located outside the clothes drying drum 100 to connect with the rotary joint 400.

[0089] In this embodiment, the screws 315 penetrate the wall 120 of the clothes drying drum 100 and are inserted into the mounting portion 314 , thereby achieving connection between the shell 310 and the wall 120 and fixing the lifting ribs 300 on the wall 120 .

[0090] Preferably, the lifting ribs 300 extend parallel to the central axis of the drying drum 100, and the blowing pipeline 320 includes a blowing section 520 extending in the same direction as the lifting ribs 300, and a gas delivery section 510 connecting the blowing section 520 and the rotary joint 400. The blowing section 520 passes through one end of the housing 310 close to the bottom 110 of the drying drum 100 and passes through the bottom 110 of the drying drum 100.

[0091] In the above scheme, the lifting rib 300 installed in the dryer 100 has a hollow chamber, and an air outlet 301 is opened on the shell 310 of the lifting rib 300. The blowing section 520 of the blowing pipeline 320 extends into the interior of the hollow chamber, and blows air into the dryer 100 through the air outlet 301 on the shell 310.

[0092] On the one hand, the above arrangement can play a role in blowing away the clothes covered on the lifting ribs 300, and to a certain extent eliminate the phenomenon of clothes being entangled in the rotating clothes drying drum 100 when drying. On the other hand, the shell 310 of the lifting ribs 300 can also protect the air blowing pipeline 320 inside it. The clothes in the clothes drying drum 100 only contact the outer surface of the shell 310, and will not directly collide with the air blowing pipeline 320 and the nozzle 330 sleeved on the air outlet 321 during the process of being thrown inside the clothes drying drum 100 as the clothes drying drum 100 rotates, causing damage to the air blowing pipeline 320 or the nozzle 330.

[0093] In this embodiment, the drying of clothes is achieved by passing high-temperature dry air into the drying drum 100. Specifically, a drying air duct is fixedly arranged inside the dryer, in which a fan is arranged. The air inlet end of the drying air duct is arranged at one side of the tube mouth of the drying drum 100, and moist air is drawn into the drying air duct from the tube mouth of the drying drum 100 by the fan. The air outlet end of the drying air duct is arranged at one side of the bottom 110 of the drying drum 100, and a plurality of drying air inlet holes 111 are provided on the bottom 110 of the drying drum 100. The moist air entering the drying air duct from the air inlet end is transported from front to back, and after being dehumidified and heated inside the drying air duct, it enters the drying drum 100 from the air outlet end through the drying air inlet holes 111, contacts the clothes in the drying drum 100, takes out the moisture in the clothes, and becomes moist air and enters the drying air duct again.

[0094] In the above scheme, the clothes are dried by the air circulation in the drying duct and the drying drum 100. During the drying process, air is blown through the blowing pipe 320 so that the gas is blown out through the air outlet 301 on the shell 310 of the lifting rib 300, which has a certain blowing effect on the clothes being dried and prevents the clothes from being seriously entangled during the drying process.

[0095] In this embodiment, the air supply pipeline is connected to the air source to deliver air to the air blowing pipeline 320, so as to achieve the purpose of blowing air into the clothes drying drum 100. Specifically, the outlet end of the air supply pipeline is connected to the gas inlet 411 on the rotary joint 400, and the air inlet end of the air supply pipeline is connected to the air generator disposed inside the clothes dryer, or the air inlet end of the air supply pipeline extends out of the clothes dryer for connecting to an external air source.

[0096] An air generator is set inside the dryer as an air source, and the dryer can operate independently. It is more suitable for small and medium-sized household dryers and is easy to use. For large commercial dryers, it is not necessary to set an additional air source inside the dryer. Instead, the air inlet end of the air supply pipeline is set outside the dryer and directly connected to the industrial air source for air supply. The above method does not occupy the internal space of the dryer, so that the capacity of the dryer drum 100 can be set larger. At the same time, the industrial air source can more easily provide a larger air pressure. For large-capacity dryers 100, it can also provide sufficient airflow intensity to ensure the blowing effect of clothes.

[0097] In a further solution of this embodiment, a sensor is provided on the housing 310 and a control valve is provided on the air blowing pipeline 320. The control valve opens when the sensor detects that the housing 310 is covered by clothes, so as to blow air to the clothes covered on the housing 310.

[0098] In this embodiment, the sensor may be a pressure sensor or a proximity switch disposed on the housing 310. When the pressure detected by the pressure sensor increases significantly, or when the proximity switch detects an object approaching, a feedback signal is sent to control the control valve to open, so that the gas in the blowing pipeline 320 is blown out through the air outlet 301 on the housing 310, blowing away the clothes covering the housing 310, and preventing the clothes from further entanglement and affecting the drying effect.

[0099] In the above scheme, by setting sensors and control valves, the timing of the air blowing pipeline 320 to blow air to the outside of the shell 310 of the lifting ribs 300 during the clothes drying process can be controlled. When the clothes are covered on the shell 310, air is blown to the outside of the shell 310 to ensure that the blown gas effectively acts on the clothes, thereby improving the blowing effect on the clothes.

[0100] In this embodiment, two lifting ribs 300 are symmetrically arranged in the clothes drying drum 100, and correspondingly, two blowing pipes 320 are symmetrically arranged, respectively connected to two gas outlets 421 on the rotating end 420 of the rotary joint 400. The number of lifting ribs 300 can be further increased, so that multiple positions along the circumference of the wall 120 of the clothes drying drum 100 can blow air into the clothes drying drum 100, further improving the effect of blowing away the clothes and better reducing the effect of clothes entanglement.

[0101] The clothes dryer of this embodiment is provided with a fixed air supply pipeline and an air blowing pipeline 320 that can rotate synchronously with the clothes drying drum 100. The fixed air supply pipeline and the rotatable air blowing pipeline 320 are connected by a rotary joint 400, so as to achieve the purpose of blowing air into the clothes drying drum 100. The structure is simple and easy to implement. Air is blown into the clothes drying drum 100 through the air blowing pipeline 320 to disperse the clothes and prevent the clothes from being seriously entangled during the drying process.

[0102] The air blowing pipeline extends into the drying drum 100 and is partially disposed in the housing 310 of the lifting rib 300, so as to prevent the air blowing pipeline 320 from directly contacting the clothes, and in particular, to prevent the clothes from colliding with the air outlet 321 and the nozzle 330 on the air blowing pipeline 320, thereby preventing the structure of the air blowing pipeline 320 from being damaged. At the same time, it also prevents the air blowing pipeline 320 from scratching against the clothes, thereby preventing the clothes from being damaged.

[0103] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
