DETAILED DESCRIPTION

[0026] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "fixed" should be understood broadly, for example, can be fixedly connected, can be detachably connected or integrated; can be mechanically connected, can be electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] In the present application, unless otherwise explicitly specified and limited, the "upper" or "lower" of the first feature to the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the "upper", "above" and "on" of the first feature to the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The "below", "under" and "under" of the first feature to the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0029] After the clothes are washed, the clothes are also subjected to dewatering treatment for the purpose of facilitating faster drying. In the related art, when the clothes are subjected to dewatering, the existing washing device (e.g., a washing machine or a dewatering machine) drives the clothes to perform centrifugal motion by high-speed rotating the inner drum, thereby realizing dewatering treatment of the clothes in a spin-drying manner. However, the dewatering manner of high-speed rotating the inner drum causes severe friction between the clothes and the drum wall during high-speed rotation, which leads to easy wear of the clothes.

[0030] Based on the above situation, the embodiment of the present application provides a clothes dewatering device, please refer to Figures 1-7 , the clothes dewatering device includes an outer drum 900, an inner drum 100, and a driving member 200. The inner drum 100 is rotationally arranged in the outer drum 900. The inner drum 100 has an inner cavity. A first passage 710 is arranged in the drum wall of the inner drum 100. The inner drum 100 is provided with a plurality of spray holes that communicate the outlet end of the first passage 710 with the inner cavity. The inlet end of the first passage 710 can pass in gas. The driving member 200 includes a main body part and an output part. The main body part is rotationally connected with the output part. The main body part is connected with the outer drum 900. The output part is connected with the inner drum 100. The driving member 200 can drive the inner drum 100 to rotate relative to the outer drum 900.

[0031] It should be noted that the spray holes are multiple. The multiple spray holes are uniformly distributed around the circumference of the inner drum 100. In the dewatering step, the multiple spray holes can spray gas to the clothes from different angular directions of the inner drum 100, which is conducive to improving the dewatering efficiency of the clothes. The bottom of the inner drum 100 is provided with a drain port. The drain port can discharge the moisture carried out of the clothes by the gas and the moisture spun out of the clothes by the inner drum 100 during rotation. The clothes dewatering device of the embodiment is not limited to a washing machine, a dewatering machine, but can also be a dryer or other device with dewatering function.

[0032] Taking an example that the inner drum 100 is driven by the driving member 200 to rotate at a low speed of 200 rpm-300 rpm, through the low-speed rotation of the inner drum 100 and the increase of the gas spraying, the following table of dewatering data is obtained:

[0033]

[0034] It is obvious that from the above table, with the increase of the dewatering time, the weight of the clothes after dewatering and the moisture content are continuously reduced. When the dewatering time of the clothes reaches 20 minutes, the moisture content of the clothes of the inner drum 100 with a rotation speed of 200 rpm is 101.2%, the moisture content of the clothes of the inner drum 100 with a rotation speed of 250 rpm is 87.5%, and the moisture content of the clothes of the inner drum 100 with a rotation speed of 300 rpm is 71.0%, all of which meet the requirement that the moisture content of the clothes after dewatering should be less than 115% according to the national standard.

[0035] It can be seen that the laundry dewatering device provided by the application can use gas to take out the moisture of the laundry by adding a jet mode to the inner cylinder 100, and the dewatering requirement of the laundry can be met without high-speed rotation of the inner cylinder 100 as in a common washing machine, so that the inner cylinder 100 can be allowed to rotate at a low speed. During dewatering, the inner cylinder 100 is driven to rotate at a low speed by the driving member 200, and gas is introduced into the first channel 710 so as to be sprayed into the inner cavity of the inner cylinder 100 through the spray holes. The sprayed gas can hit the laundry to squeeze out the moisture or take out the moisture through the laundry. In combination with the driving of the inner cylinder 100 by the driving member 200, the moisture in the laundry can be discharged from the inner cylinder 100. In addition, the inner cylinder 100 rotates at a low speed during the dewatering process, which can reduce the degree of friction between the laundry and the barrel wall during rotation, and is beneficial to avoiding the abrasion of the laundry during the dewatering process, and effectively solves the technical problem that the laundry is easily abraded when being dewatered by high-speed rotation in the existing cleaning device.

[0036] It can be seen that Figure 2 In an embodiment, a negative pressure mechanism 300 is further included, and the negative pressure mechanism 300 is arranged on the outer cylinder 900. The suction part of the negative pressure mechanism 300 is in communication with the inner cavity. Taking an example of driving the inner cylinder 100 to rotate at a low speed of 250 rpm-300 rpm by the driving member 200, the dewatering data in the following table is obtained by increasing the jet or increasing the jet and the negative pressure at the same time.

[0037]

[0038] It is obvious that from the above table, when the dewatering time of the laundry reaches 20 minutes, the moisture content of the laundry is less than 115% whether the dewatering mode of low-speed rotation plus jet or the dewatering mode of low-speed rotation plus jet combined with negative pressure is used, that is, the moisture content of the laundry after dewatering meets the requirement of the national standard that the moisture content of the laundry after dewatering should be less than 115%, and the dewatering effect of the dewatering mode of low-speed rotation plus jet combined with negative pressure is obviously better than that of the dewatering mode of low-speed rotation plus jet.

[0039] It can be seen that by increasing the negative pressure mechanism 300, the dewatering effect and efficiency of the laundry dewatering device can be further improved, that is, on the basis of using the jet to take out the moisture of the laundry and cooperating with the rotation of the inner cylinder 100, the gas or moisture in the inner cavity can also be extracted by the negative pressure mechanism 300, which can accelerate the circulation speed of the gas and also accelerate the efficiency of extracting the moisture of the laundry, so as to achieve the effect of quickly dewatering the laundry.

[0040] It should be noted that Figure 2The negative pressure mechanism 300 comprises a negative pressure box 310 and a negative pressure pump 320 connected with the negative pressure box 310 through a pipeline. The negative pressure box 310 is arranged below the inner cylinder 100 and is provided with a suction part. The inner cylinder 100 is provided with water suction ports in a closed state. During rotation of the inner cylinder 100, part of the water suction ports is always in a position corresponding to the suction part. When the clothes are dehydrated, the suction part of the negative pressure box 310 cooperates with part of the water suction ports of the inner cylinder 100 to form a negative pressure effect at the water suction ports to realize opening of the water suction ports, so that the pressure difference between the negative pressure box 310 and the inner cylinder 100 is used to suck away air in the inner cavity or water on the clothes.

[0041] In an embodiment, a gas supply device is further included, which is in communication with the inlet end of the first channel 710. The gas supply device is used to supply high-pressure gas into the inner cavity. The high-pressure gas is gas with a gas pressure of 10 MPA or above. The high-pressure gas is sprayed into the inner cavity of the inner cylinder 100 through the first channel 710. The high-pressure gas can not only improve the striking effect of the gas on the clothes to make the sprayed gas better strike the clothes to squeeze out water or pass through the clothes to take out water, which is beneficial to improve the separation efficiency of water on the clothes, but also better cooperate with the negative pressure mechanism 300 to accelerate the air circulation speed in the inner cavity of the inner cylinder 100 so that the gas can take away the separated water from the clothes faster.

[0042] It should be noted that the gas supply device is an air compressor, a high-pressure gas tank, a high-pressure gas source device or other devices that can provide high-pressure gas.

[0043] Please refer to Figure 1 The inner cylinder 100 comprises a cylinder body 110 and a lifting rib 120 arranged on the inner wall of the cylinder body 110. The spray hole is arranged in the lifting rib 120, and the lifting rib 120 is provided with a spray cavity 121 in communication with the spray hole and the first channel 710. The lifting rib 120 can not only appropriately improve the kneading effect on the clothes by following the rotation of the inner cylinder 100 to achieve better washing effect, but also provide space for arrangement of the spray cavity 121 so that the first channel 710 can be in communication with multiple spray holes at the same time to ensure that each spray hole has a relatively uniform spraying effect in the inner cylinder 100. In addition, the lifting rib 120 can also reduce the distance between the spray hole and the clothes to some extent so that the gas or cleaning liquid sprayed from the spray hole can more easily contact the clothes to better spray and wash or dehydrate the clothes in the inner cylinder 100.

[0044] Please refer to Figures 1-2The lifting ribs 120 are arranged around the circumference of the cylinder body 110, the number of the first channels 710 is the same as the number of the lifting ribs 120, and the first channels 710 are arranged one by one corresponding to the lifting ribs 120. The arrangement of the plurality of lifting ribs 120 can provide the jet holes of the first channels 710 with the ability to communicate with the inner cavity of the inner cylinder 100 from different directions, so that in the dehydration process, each jet hole can hit or pass through the clothes from different directions to squeeze out the water, which is beneficial to improve the dehydration effect of the clothes. When the cleaning liquid is introduced into the first channels 710, that is, in the clothes washing process, each jet hole can spray or flush the clothes from different directions, which is also beneficial to improve the washing effect of the clothes.

[0045] It should be noted that the number of the lifting ribs 120 can be two, three, four or other numbers, and the specific number of the lifting ribs 120 can be selected as needed.

[0046] In an embodiment, please continue to refer to Figures 1-2 The driving member 200 is a motor, and the output portion is an output shaft 210. The inside of the output shaft 210 is provided with a second channel 720 corresponding to the first channel 710 one by one, and the inlet end of the first channel 710 communicates with the corresponding second channel 720. The output shaft 210 with the second channel 720 inside can provide a path for the first channel 710 to connect external equipment, so as to realize the spraying of gas or the spraying of cleaning liquid into the inner cavity along the first channel 710. Since the output shaft 210 is connected with the inner cylinder 100, the inner cylinder 100 will rotate with the output shaft 210, so that the second channel 720 in the output shaft 210 can always communicate with the corresponding first channel 710 during the rotation of the inner cylinder 100, meeting the dehydration treatment of the clothes by rotating and spraying gas.

[0047] It should be noted that each second channel 720 in the output shaft 210 is not communicated and isolated from each other, so that the second channel 720 and the corresponding first channel 710 can be accurately connected, avoiding the occurrence of gas or water leakage in the output shaft 210. In an embodiment, the inner cylinder 100 is further provided with a multi-leg support 130, the multi-leg support 130 is provided with a plurality of legs, the legs are provided with a communication channel 131, and one end of the output shaft 210 can be arranged in the multi-leg support 130, so that the communication channel 131 in each leg can communicate the second channel 720 in the output shaft 210 with the corresponding first channel 710 in the cylinder wall of the inner cylinder 100, thereby meeting the needs of spraying gas or spraying cleaning liquid into the inner cavity of the inner cylinder 100. The number of legs of the multi-leg support 130 is the same as the number of the lifting ribs 120, for example, when the number of the lifting ribs 120 is three, the multi-leg support 130 is a three-leg support.

[0048] Please refer to Figures 3-4The rotating joint 400 comprises an outer housing 410 and a rotating shaft 420 which is rotatably installed in the outer housing 410, and the rotating shaft 420 is connected with the output shaft 210. The outer housing 410 and the rotating shaft 420 are provided with third channels 730 corresponding to the second channels 720. The inlet end of the second channel 720 is communicated with the corresponding third channel 730. The rotating shaft 420 of the rotating joint 400 is connected with the output shaft 210 of the motor, and the outer housing 410 of the rotating joint 400 can be connected with the external structure, so that the rotating shaft 420 can rotate with the output shaft 210 of the motor, and the outer housing 410 and the external pipeline of the outer housing 410 cannot rotate with the inner cylinder 100, so that the external pipeline cannot be wound. At the same time, the third channel 730 in the rotating joint 400 can be communicated with the corresponding second channel 720 in the output shaft 210, so that the gas or cleaning liquid can be sprayed into the inner cavity of the inner cylinder 100 through the third channel 730 and along the second channel 720 and the first channel 710.

[0049] It should be noted that please continue to refer to Figures 3-4 The outer housing 410 is provided with a first circumferential hole 411 in the circumferential direction. The rotating shaft 420 is rotatably installed in the outer housing 410. The rotating shaft 420 is provided with an axial hole 421 in the axial direction. The rotating shaft 420 is provided with a second circumferential hole 422 in the circumferential direction, which can communicate the axial hole 421 and the first circumferential hole 411. The first circumferential hole 411, the second circumferential hole 422 and the corresponding axial hole 421 are sequentially communicated to form the third channel 730. The outer housing 410 and the rotating shaft 420 are provided with a sealing structure, which can ensure that the outer housing 410 can rotate relative to the rotating shaft 420, and the third channel 730 in the rotating joint 400 can be communicated with the second channel 720 in the output shaft 210. When the lifting ribs 120 are provided with a plurality of lifting ribs, the number of the second channels 720 and the third channels 730 is also a plurality. The first circumferential holes 411 which form different third channels 730 are located on different circumferences of the outer housing 410, so as to ensure that the third channels 730 do not interfere with each other, and the third channels 730 can be communicated with the corresponding second channels 720, so that the sequentially communicated third channels 730, the second channels 720 and the first channels 710 can provide gas for the nozzles of different lifting ribs 120, so as to realize the gas spraying to the clothes in the inner cavity of the inner cylinder 100 from different directions, so as to assist the low-speed rotation of the inner cylinder 100 by the negative pressure mechanism 300 and the driving member 200 to complete the dehydration treatment of the clothes.

[0050] Please refer to Figure 5Also included is a multi-way valve 500 connected with the outer housing 410, the multi-way valve 500 having a first inlet 510 and a plurality of first outlets 520, the first outlets 520 corresponding one-to-one with the third channels 730, the inlet end of the third channels 730 being in communication with the corresponding first outlets 520. The plurality of first outlets 520 of the multi-way valve 500 can be respectively in communication with the third channels 730 of the rotary joint 400, the valve 530 of the first outlet 520 can be controlled to be closed or opened according to needs, so as to realize fine control of the spray washing path formed by the third channels 730, the second channels 720 and the first channels 710, and to meet the needs of the user to control the spray holes on the lifting ribs 120 to not spray air or water, which is beneficial to expand the application range of the equipment.

[0051] It should be noted that each first outlet 520 is provided with a valve 530 capable of controlling the opening or closing of the first outlet 520, and in the normal state, each first outlet 520 is in communication with the first inlet 510. As an embodiment, the lifting ribs 120 are three, and the multi-way valve 500 is a three-position four-way valve, that is, the first outlets 520 of the multi-way valve 500 are three, and the three first outlets 520 are respectively provided with independent valves 530. According to the number of the lifting ribs 120, the multi-way valve 500 can also be a five-way valve, a six-way valve, etc., which will not be described one by one in this embodiment.

[0052] Please refer to Figure 7The inner cylinder 100 is provided with inductive switches 820 corresponding to the lifting ribs 120 one by one, the multi-way valve 500 includes several valves 530 respectively used for controlling the opening and closing of the first outlets 520, each inductive switch 820 is in communication connection with the valve 530 corresponding to the lifting rib 120, the outer cylinder 900 is provided with a switch trigger 810 located directly below the lowest point of the inner cylinder 100, when the lifting rib 120 moves to the lowest point of the inner cylinder 100, the switch trigger 810 triggers the inductive switch 820 corresponding to the lifting rib 120, and the inductive switch 820 triggers the valve 530 corresponding to the inductive switch 820 to close the first outlet 520. When a certain inductive switch 820 senses the switch trigger 810, at this time, the inductive switch 820 is directly below the inner cylinder 100, at this time, the switch trigger 810 triggers the inductive switch 820, and then the inductive switch 820 sends a signal to the valve 530 of the first outlet 520 to close the first outlet 520 in time. During dehydration, the path where the lifting rib 120 located at the lowest point is in a gas supply interruption state, that is, the jet hole where the lifting rib 120 located at the lowest point of the inner cylinder 100 does not spray gas to the clothes in the inner cavity of the inner cylinder 100, only the jet hole where the lifting rib 120 located above the clothes can spray gas to the clothes in the inner cavity of the inner cylinder 100. Since during the rotation, the lifting rib 120 located at the lowest point is relatively close to the suction part of the negative pressure mechanism 300 when spraying gas to the inner cavity of the inner cylinder 100, the gas sprayed by the lifting rib 120 is directly sucked away by the negative pressure mechanism 300, so that the water content of the gas is very low, and the normal suction of the negative pressure mechanism 300 is also disturbed. The embodiment can stop the lifting rib 120 located at the lowest point from spraying gas in time through the inductive switch 820, so as to avoid the influence of the lifting rib 120 located at the lowest point on the negative pressure of the negative pressure mechanism 300 on the clothes, and to ensure the dehydration efficiency of the clothes.

[0053] It should be noted that in an optional embodiment, the switch trigger 810 is a permanent magnet, and the inductive switch 820 is a magnetic inductive switch. The permanent magnet as the switch trigger 810 has good magnetic stability, which can ensure that the switch trigger 810 can stably trigger the corresponding inductive switch 820 during rotation. Of course, the inductive switch 820 can also use a proximity switch. The proximity switch identifies the distance between the inductive switch 820 and the switch trigger 810 through a proximity sensor. When the inductive switch 820 moves to a distance of a preset distance from the switch trigger 810, the inductive switch 820 is triggered, and then the valve 530 corresponding to the inductive switch 820 is closed.

[0054] Please refer to Figure 6The three-way valve 600 is connected with the multi-way valve 500, and has a second outlet 620 and two second inlets 610, which can be used to introduce gas or cleaning liquid respectively, and the second outlet 620 is communicated with the first inlet 510. The three-way valve 600 is internally provided with a movable switching valve 630, which can switch the second outlet 620 to communicate with any one of the second inlets 610. Through the arrangement of the three-way valve 600, gas or cleaning liquid can be introduced according to the corresponding requirements of the clothes. When the clothes need to be cleaned, the cleaning liquid can be introduced through one of the second inlets 610. When the clothes need to be dehydrated, the switching valve 630 in the three-way valve 600 is switched to another second inlet 610 to communicate with the second outlet 620, so that gas can be introduced through the corresponding second inlet 610.

[0055] It should be noted that in the washing step, the cleaning liquid is introduced through the second inlet 610 of the three-way valve 600, and the plurality of spray holes can spray water from different angle directions of the inner drum 100 to wash the clothes, which is beneficial to improve the cleaning effect of the clothes. In the dehydration step, gas is introduced through the second inlet 610 of the three-way valve 600, and the plurality of spray holes can spray gas to the clothes from different angle directions of the inner drum 100, which is beneficial to improve the dehydration efficiency of the clothes.

[0056] In an alternative embodiment, the number of lifting ribs 120, the number of first channels 710, the number of second channels 720, the number of third channels 730, the number of first outlets 520 and the number of valves 530 are all three, that is, the inner drum 100 is provided with at least three direction spray holes. In this way, by arranging a relatively small number of lifting ribs 120, the cleaning effect and dehydration effect of the clothes can be ensured, and the problem of high processing cost of the clothes dehydration equipment caused by too many lifting ribs 120 can be avoided.

[0057] The embodiment of the present application also provides a clothes dehydration method applied to the clothes dehydration equipment described above, and the clothes dehydration method comprises the following steps: starting the driving member 200 to drive the inner drum 100 to rotate at a speed lower than or equal to 300 rpm, introducing gas into the first channel 710, and spraying the gas into the inner cavity of the inner drum 100 through the spray hole. By using the gas spraying method, the water in the clothes can be taken out by the gas, and the dehydration requirement of the clothes can be met without high-speed rotation of the inner drum 100, so that the inner drum 100 can be allowed to rotate at a low speed, which is beneficial to avoid the abrasion of the clothes in the dehydration process, and effectively solves the technical problem that the clothes are easily abraded when the clothes are dehydrated by high-speed rotation of the existing cleaning equipment.

[0058] In an embodiment, the clothes dehydration method further comprises: starting the negative pressure mechanism 300 to extract the gas and moisture in the inner cavity, and through the gas injection and the negative pressure extraction of the moisture of the clothes by the negative pressure mechanism 300, the circulation of the gas injection and the gas extraction in the inner cavity of the inner drum 100 is realized, which is beneficial to reduce the moisture content of the clothes, especially the high-pressure gas injection can better reduce the moisture content of the clothes, and in combination with the driving of the driving member 200 to the inner drum 100, the dehydration effect of the clothes is better, and the dehydration time of the clothes is shortened. In the dehydration process, the inner drum 100 rotates at a low speed, which can reduce the friction between the clothes and the barrel wall in the rotation process, and is beneficial to avoid the abrasion of the clothes in the dehydration process.

[0059] It should be noted that the gas introduced into the first channel 710 can be high-pressure gas, the driving member 200 drives the inner drum 100 to rotate at a low speed, and the low speed is lower than or equal to 300 rpm. In an embodiment, the driving member 200 drives the inner drum 100 to rotate at a speed of 200 rpm-300 rpm, so as to ensure that the inner drum 100 rotates at a relatively appropriate speed in the low speed.

[0060] In addition, under the premise of being provided with the three-way valve 600, the clothes dehydration method further comprises: before the clothes are dehydrated, the clothes are also washed, the three-way valve 600 is controlled to switch to the communication between one of the second inlets 610 and the second outlet 620, so that the cleaning liquid is injected into the inner cavity of the inner drum 100 through the second inlet 610, so as to achieve the effect of washing the clothes; when the clothes are dehydrated, the three-way valve 600 is controlled to switch to the communication between the other second inlet 610 and the second outlet 620, so that the gas is introduced into the inner cavity of the inner drum 100 through the other second inlet 610; after the clothes are dehydrated, the clothes are also dried. Through drying, the dehydration efficiency of the clothes can be accelerated, and the subsequent drying efficiency of the clothes can be improved.
