Description

TECHNICAL FIELD

[0001] The utility model relates to clothes washing technical field, especially a clothes treatment device. BACKGROUND

[0002] In recent years, in the field of washing machines, the traditional washing machine design usually focuses on cleaning effect, water saving and energy saving, etc., and ignores the problems of moisture, peculiar smell and air not circulating generated in the use process of washing machines. The washing machine is in a humid environment for a long time, which is easy to breed microorganisms such as mold and bacteria, thereby affecting the clothes washing quality and the service life of the washing machine.

[0003] The existing washing machine does not have a special air conditioning or moisture discharge system, and the internal air does not circulate, which aggravates the moisture retention. This not only leads to the generation of peculiar smell in the washing machine, but also may cause corrosion or damage to the electrical components and metal parts in the washing machine. For the washing machine installed with a fresh air system, since the fresh air system needs to blow air into the drum, the fresh air system needs to communicate with the barrel by using a pipeline. When the washing machine starts normal cleaning and the fresh air system is closed, the foam in the washing machine is easy to overflow to the fresh air system through the pipeline, causing damage to the fresh air system. When the washing machine stops cleaning and the fresh air system is turned on, in the prior art, when the fresh air blows into the drum, the gas in the drum directly flows out through the gap of the drum, and the user cannot intuitively perceive whether the fresh air is turned on, thereby causing the user to have doubts when using, and further unable to further improve the user's experience.

[0080] In the description of the present embodiment, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", "front", "back", etc. indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present utility model.

[0081] As a specific embodiment of the present utility model, such as Figure 1 and Figure 2As shown, the present embodiment also provides a clothes treatment device 100, which can include a drum 110, a fresh air assembly 130, a front panel, and an air return system 140. Specifically, the fresh air assembly 130 is in communication with the drum 110 and controlled to introduce fresh air into the interior of the drum 110. The front panel is located in front of the drum 110, and the front panel is provided with an air vent 114. The air return system 140 can include an air inlet pipe 141 and a first air outlet pipe 142, the air inlet pipe 141 is in communication with the drum 110 so that the gas in the drum 110 enters the air return system 140 through the air inlet pipe 141. The outlet end of the first air outlet pipe 142 is arranged at the air vent 114, so that the gas entering the air return system 140 flows to the air vent 114 through the first air outlet pipe 142 and then flows out.

[0082] Specifically, the clothes treatment device 100 of the present embodiment can be a washing machine. After the washing of clothes is completed, the inside of the washing machine is prone to mold and bacteria due to moisture, which in turn causes odor in the inside of the washing machine. The clothes treatment device 100 of the present embodiment is provided with a fresh air assembly 130, which can blow fresh air into the drum 110 when the washing machine is not in use, so that the inside of the drum 110 remains dry, reducing the growth of mold and bacteria, and thus improving the washing quality and service life of the clothes.

[0083] Specifically, the clothes treatment device 100 of the present embodiment can include a drum 110, a fresh air assembly 130, a front panel, and an air return system 140. When the fresh air assembly 130 circulates gas into the interior of the drum 110, the gas in the drum 110 is circulated to the air vent 114 of the front panel through the first air outlet pipe 142 of the air return system 140. On the one hand, the gas in the drum 110 is conveniently discharged, and on the other hand, at the front panel, the user can intuitively feel whether the fresh air assembly 130 is started, thereby dispelling the user's doubts and improving the use experience.

[0084] Specifically, when the front panel in front of the drum 110 includes a control panel 113 and a front door, the air vent 114 can be arranged at the control panel 113 or at the front door. For example, the air vent 114 in the present embodiment is arranged at the control panel 113. When the front panel in front of the drum 110 only includes the front door (that is, the control panel 113 and the front door are integrated), the air vent 114 is directly arranged at the front door, and the specific position of the air vent 114 can be freely selected according to actual conditions.

[0085] The following will be specifically described with the air vent 114 arranged at the control panel 113 as an example. In addition, the structure of the control panel and the front door in one piece is similar to the present embodiment, and thus will not be described in detail.

[0086] In this embodiment, a detergent dispenser 120 is provided on the outer side of the cylinder 110, and a return air system 140 is located behind the detergent dispenser 120. In this embodiment, a first air outlet duct 142 extends from the return air system 140 along the side of the detergent dispenser 120 to the inner side of the control panel 113, and then extends along the inner side of the control panel 113 to the vent 114. The cross-sectional shape of the first air outlet duct 142 can be designed according to the specific situation. For example, in this embodiment, the cross-section of the first air outlet duct 142 on the side of the detergent dispenser 120 is circular, while the cross-section on the rear side of the control panel 113 is square.

[0087] Furthermore, the shape of the vent 114 in this embodiment can also be designed according to actual needs. Generally, the shape of the vent 114 can be designed according to the style of the buttons and other components on the control panel 113. In this embodiment, the vent 114 is square.

[0088] More specifically, in this embodiment, the vent 114 is located on the side of the control buttons on the control panel 113. Generally, one or more control buttons are provided on the control panel 113. To avoid overlap with the control buttons, this embodiment places the vent 114 on the side of the control buttons, without affecting the use of the control buttons.

[0089] More specifically, in this embodiment, the vent 114 and the control buttons on the control panel 113 are on the same horizontal line.

[0090] In this embodiment, placing the vent 114 on the same horizontal line as the control buttons on the control panel 113 can enhance the aesthetics of the control panel 113 and avoid the problem of the control panel 113 being unattractive due to the vent 114 being randomly placed on the control panel 113.

[0091] Specifically, such as Figures 2-4 As shown, in this embodiment, the detergent dispenser 120 is connected to the drum body 110. The return air system 140 may include a second air outlet duct 143, which is connected to the detergent dispenser 120. The gas entering the return air system 140 from the air inlet 1364 is selectively discharged after flowing through the first air outlet duct 142 to the vent 114, or flows through the second air outlet duct 143 to the detergent dispenser 120.

[0092] Specifically, the air return system 140 of the embodiment can include a first air outlet pipe 142 and a second air outlet pipe 143, the first air outlet pipe 142 being in communication with the air hole 114 and in turn being in communication with the outside, and the second air outlet pipe 143 being in communication with the detergent box 120. When the laundry treatment device 100 stops working and the fresh air is turned on, the air in the drum can be discharged to the outside through the first air outlet pipe 142 at this time, and when the laundry treatment device 100 starts working and the fresh air is turned off, the air of the air return system 140 can be discharged to the detergent box 120 through the second air outlet pipe 143 at this time, so that the foam in the laundry treatment device 100 can also be directly discharged to the detergent box 120 and then flow back to the drum 110 from the detergent box 120, avoiding the foam from damaging the fresh air system or directly overflowing to the outside, and improving the use experience of the laundry treatment device 100.

[0093] As a specific embodiment of the utility model, as shown in Figure 5 and Figure 6 , the air return system 140 of the embodiment can include a reversing valve 144, which can include an air inlet 1441, a first air outlet 1442, a second air outlet 1443 and a first valve plate 1444. The air inlet 1441 is connected with the air inlet pipe 141. The first air outlet 1442 is connected with the first air outlet pipe 142. The second air outlet 1443 is connected with the second air outlet pipe 143. The first valve plate 1444 is controlled to selectively seal the first air outlet 1442 or the second air outlet 1443.

[0094] Specifically, the air return system 140 of the embodiment takes in air through the air inlet 1441 and selects the first air outlet 1442 or the second air outlet 1443 through the first valve plate 1444, so that the air can be selectively guided to the outside or the detergent box 120 as needed, thereby enhancing the transmission efficiency of the fresh air while avoiding the influence of foam overflow on the use experience.

[0095] As a specific embodiment of the utility model, as shown in Figure 5 and Figure 6 , the air return system 140 of the embodiment can further include a motor 145 and a first rotating shaft 146. The motor 145 can include an output shaft. One end of the first rotating shaft 146 is connected with the output shaft to rotate with the output shaft, and the other end is connected with the first valve plate 1444 to make the first valve plate 1444 rotate with the first rotating shaft 146. The first valve plate 1444 of the embodiment is driven to rotate by the motor 145, and the output shaft is further driven to rotate the first valve plate 1444, so that the valve plate can selectively seal the first air outlet 1442 or the second air outlet 1443, and the air flow in the drum 110 can flow out through the first air outlet 1442 or the second air outlet 1443, thereby enhancing the transmission efficiency of the fresh air and avoiding the overflow of the foam in the drum 110.

[0096] As a specific embodiment of the utility model, as shown in the figure, Figure 5 The return air system 140 of the embodiment can also include a first mounting seat 147 and a second mounting seat 148. The first mounting seat 147 is connected with the detergent box 120. The first mounting seat 147 has an air inlet 1441 and a first through hole 1471. The motor 145 is installed on one side of the first mounting seat 147 and extends to the other side through the first through hole 1471. The first air outlet 1442 and the second air outlet 1443 are located at the second mounting seat 148. The second mounting seat 148 is connected with the first mounting seat 147 to form a containing space to contain the first rotating shaft 146 and the first valve plate 1444.

[0097] Specifically, the first mounting seat 147 of the embodiment is formed as a cavity structure with an opening, and the opening is connected with the second mounting seat 148. The motor 145 is arranged on the left side of the first mounting seat 147. The output shaft of the motor 145 extends into the cavity on the right side through the first through hole 1471 and is connected with the first rotating shaft 146. The first rotating shaft 146 drives the first valve plate 1444 to rotate. The second mounting seat 148 is connected on the right side of the first mounting seat 147, and the first air outlet 1442 and the second air outlet 1443 are arranged at the second mounting seat 148. The first valve plate 1444 can selectively block the first air outlet 1442 or the second air outlet 1443 when rotating.

[0098] The first mounting seat 147 is provided with an outwardly extending mounting portion. The rear of the detergent box 120 is provided with a mounting bracket 150. The mounting bracket 150 can support the suction pump 160 for sucking laundry liquid on one side and can be connected with the mounting portion 1472 of the first mounting seat 147 on the other side, thereby mounting and supporting the first mounting seat 147. Specifically, the mounting portion 1472 can include at least two mounting portions, which are installed on the mounting bracket 150 by screws.

[0099] As a specific embodiment of the utility model, as shown in the figure, Figure 6 The output shaft and the first through hole 1471 of the embodiment are provided with a sealing ring 1451 to avoid gas flowing into the containing space from the gap between the output shaft and the first through hole 1471. The sealing ring 1451 in the embodiment can be a rubber sealing ring 1451.

[0100] As a specific embodiment of the utility model, as shown in the figure, Figure 5 and Figure 6As shown, the second mounting seat 148 of the embodiment is provided with a second through hole 1481 and a third through hole 1482 at the side wall close to the accommodating space, the second through hole 1481 is communicated with the first gas outlet 1442, and the third through hole 1482 is communicated with the second gas outlet 1443. The first valve piece 1444 abuts at the side wall, and when the first valve piece 1444 is controlled to rotate, the second through hole 1481 or the third through hole 1482 is selectively blocked, so that the gas is selectively discharged from the first gas outlet 1442 or the second gas outlet 1443.

[0101] Specifically, the second through hole 1481 and the third through hole 1482 of the embodiment can be circular or any other shape, which only needs to meet the condition that the second through hole 1481 is communicated with the first gas outlet 1442 and the third through hole 1482 is communicated with the second gas outlet 1443. The shape of the second through hole 1481 of the embodiment is preferably the same as the cross-sectional shape of the first gas outlet 1442, which is circular. The shape of the third through hole 1482 is the same as the cross-sectional shape of the second gas outlet 1443, which is also circular.

[0102] The side wall of the embodiment is a planar structure, and the first valve piece 1444 abuts against the side wall, which is also a planar structure. The first valve piece 1444 can block the second through hole 1481 and the third through hole 1482 when rotating, and then can selectively open the second gas outlet 1443 or the first gas outlet 1442, so that the gas is selectively flowed out from the second gas outlet 1443 or the first gas outlet 1442.

[0103] As a specific embodiment of the utility model, the second mounting seat 148 of the embodiment can further include a fourth through hole 1483 located at the side of the second through hole 1481 and the third through hole 1482. The side of the first valve piece 1444 away from the first rotating shaft 146 can include a first protrusion, and the first protrusion is arranged at the fourth through hole 1483 to enable the first valve piece 1444 to rotate at the fourth through hole 1483.

[0104] Specifically, the fourth through hole 1483 is arranged at the second mounting seat 148, and a first protrusion (not shown in the figure) matched with the fourth through hole 1483 is arranged at the first valve piece 1444, the cross section of the fourth through hole 1483 is circular, the cross section of the first protrusion is also circular, and the outer side wall of the first protrusion is in contact with the inner side wall of the fourth through hole 1483, so that the first valve piece 1444 can rotate at the fourth through hole 1483, avoiding the first valve piece 1444 from translating relative to the second mounting seat 148 due to external force, and then avoiding component vibration and abnormal sound.

[0105] As a specific embodiment of the utility model, one side of the first valve piece 1444 close to the first rotating shaft 146 is provided with a second protrusion 1446, the cross section of the second protruous 1446 is annular, and the second protrusion 1446 has a notch 1447. The first rotating shaft 146 is provided with a limiting block 1461, the first rotating shaft 146 abuts in the second protrusion 1446, and the limiting block 1461 cooperates with the notch 1447 to make the first valve piece 1444 rotate with the first rotating shaft 146.

[0106] Specifically, one end of the first rotating shaft 146 of the embodiment is arranged at the second protrusion 1446, and the one end of the first rotating shaft 146 can be limited by the second protrusion 1446. In addition, the limiting block 1461 of the first rotating shaft 146 cooperates with the notch 1447 of the second protrusion 1446, and when the first rotating shaft 146 rotates, the first rotating shaft 146 can drive the first valve piece 1444 to rotate through the cooperation of the limiting block 1461 and the notch 1447. Specifically, the axis of the first protrusion, the second protrusion 1446 and the fourth through hole 1483 of the embodiment coincide.

[0107] Specifically, the first rotating shaft 146 of the embodiment is further provided with a first step 1462. The air return system 140 can further include an elastic member 1463, which abuts between the first step 1462 and the first valve piece 1444.

[0108] Specifically, the elastic member 1463 of the embodiment can be any component that can have a rebounding ability, and can specifically include a spring, a resilient sponge and the like. Preferably, the elastic member 1463 of the embodiment is a spring, which is arranged outside the first rotating shaft 146 and abuts between the first step 1462 and the first valve piece 1444, thereby always abutting the first valve piece 1444 at the side wall of the second mounting portion 1365, avoiding the first valve piece 1444 from leaving the side wall of the second mounting portion 1365, so that the first valve piece 1444 cannot selectively block the second through hole 1481 and the third through hole 1482.

[0109] As a specific embodiment of the utility model, as shown in Figures 7-9 The fresh air assembly 130 of the embodiment can include a fan 131, an outlet piece 132 and an air pipe 133 connected in sequence, one end of the air pipe 133 is connected with the outlet piece 132, the other end is connected with the barrel 110, so that the fan 131 blows fresh air into the barrel 110 through the outlet piece 132 and the air pipe 133 when the fan 131 is turned on. The valve assembly 134 is arranged at the outlet piece 132 to open or close the outlet piece 132.

[0110] Here, it can be understood that the clothes can be placed inside the drum 110 of the clothes treatment device 100 for treatment. The front side of the clothes treatment device 100 is provided with a clothes feeding port for feeding the clothes, and the clothes feeding port is in communication with the internal space of the drum 110, and the clothes are put into the inside of the drum 110 through the clothes feeding port.

[0111] The drum 110 is used to contain washing water, and the clothes treatment device 100 uses the washing water to perform washing treatment on the clothes in the drum 110. The drum 110 can be any structure in the prior art, such as the outer drum of a conventional washing machine, and can also be a non-porous drum washing machine, a drum that constitutes a sealed water container when the washing machine performs a washing program. Of course, the above-mentioned clothes treatment device 100 can not only be a washing machine, but also a clothes dryer, a washer-dryer, a refreshment machine, and the like.

[0112] The fresh air assembly 130 can introduce fresh air into the drum 110, and the fresh air flow performs refreshment treatment on the gas in the drum 110 to avoid the breeding of bacteria, mold or odor caused by the humid gas remaining in the drum 110. In addition, the use of the fresh air assembly 130 to update the flow of the gas in the drum 110 can achieve the blowing treatment of the clothes contained in the drum 110, which can improve the clothes treatment effect of the clothes treatment device 100.

[0113] In some embodiments, the fan 131 is a conventional device that generates a constant flow of air from the air inlet to the air outlet, such as a centrifugal fan 131, a cross-flow fan 131 or an axial flow fan 131.

[0114] As a specific embodiment of the present application, the air pipe 133 is made of rubber material, which can reduce the flow resistance of the gas and increase the stability of the clothes treatment device 100 introducing fresh air. Specifically, the air pipe 133 is a bend pipe to guide the fresh air generated by the fan 131 into the drum 110.

[0115] The air inlet end of the outlet piece 132 is connected with the fan 131, and the air outlet end is connected with the air pipe 133. The fresh air generated by the fan 131 is guided to the air pipe 133 through the outlet piece 132, and the valve assembly 134 is arranged inside the outlet piece 132. When the valve assembly 134 opens the outlet piece 132, the valve assembly 134 does not block the fresh air at the outlet piece 132, and the fresh air can flow through the outlet piece 132 and the air pipe 133 into the drum 110. When the valve assembly 134 closes the outlet piece 132, the inside of the outlet piece 132 is completely closed, which can prevent the washing agent foam from flowing back into the fan 131 when the clothes treatment device 100 is running, and can effectively reduce the risk of overflow.

[0116] The valve assembly 134 is used to open or close the outlet piece 132. When the laundry treatment device 100 is running the laundry treatment process, the valve assembly 134 closes the outlet piece 132, which can prevent the detergent foam in the drum 110 from flowing back to the fan 131 through the air duct 133, effectively reduces the risk of overflow, has a simple structure and good blocking effect. When the laundry treatment device 100 completes the laundry treatment and needs to introduce fresh air into the drum 110, the valve assembly 134 opens the outlet piece 132, which does not affect the circulation of the gas, and the fresh air at the fan 131 can smoothly pass through the air duct 133 into the drum 110 to discharge the humid gas in the drum 110, avoiding odor and bacterial growth. Compared with the prior art scheme of setting multiple blocking plates inclined and interlaced in the ventilation passage 1322, the valve assembly 134 in the above technical scheme does not affect the circulation of the gas, and has a good blocking effect on the foam.

[0117] The laundry treatment device 100 of the embodiment has a simple structure, the valve assembly 134 occupies a small space, is easy to install and has high practicability, and is also beneficial to cleaning and maintenance.

[0118] In some embodiments, the opening or closing of the valve assembly 134 can be manually or electrically controlled.

[0119] As a specific embodiment of the utility model, as shown in Figures 10-12 The outlet piece 132 can include a housing 1321 that defines a passage 1322 for gas circulation. The valve assembly 134 can include a second valve plate 1341 that is movably connected to the housing 1321 such that when the fan 131 is turned on, the second valve plate 1341 is opened under the push of the gas, and when the fan 131 is turned off, the second valve plate 1341 closes the passage 1322.

[0120] It can be understood that the fresh air generated by the fan 131 is guided to the air duct 133 through the passage 1322 of the outlet piece 132. When the fan 131 is turned off, the second valve plate 1341 completely blocks the cross section of the passage 1322, which can prevent the detergent foam from flowing back to the fan 131 through the outlet piece 132. When the fan 131 is turned on, the fresh air generated by the fan 131 can push the second valve plate 1341 to move or rotate, the second valve plate 1341 opens the passage 1322, and the gas can smoothly pass through the outlet piece 132 and the air duct 133 into the drum 110.

[0121] Specifically, the second valve piece 1341 is made of single thin PC material. When the fan 131 is turned on, the second valve piece 1341 is blown up under the pushing force of the fresh air, the channel 1322 is opened, and the fresh air flow path is smooth. When the fan 131 is turned off, the second valve piece 1341 naturally falls down under the action of no pushing force, the channel 1322 is closed, and backflow of the foam can be prevented.

[0122] In this way, the valve assembly 134 is opened when the fan 131 is turned on and closed when the fan 131 is turned off, the second valve piece 1341 is synchronized with the fan 131, so that the substances in the fresh air assembly 130 can only flow from the fan 131 to the outlet piece 132, but cannot flow from the outlet piece 132 to the fan 131, backflow of the detergent foam in the barrel 110 is prevented, and the risk of overflow of the foam can be effectively reduced. Moreover, compared with the structure using the traditional electronic one-way valve, the structure design of the second valve piece 1341 is simpler and more effective, the space occupation and the complexity of the wiring of the valve assembly 134 can be reduced, and the structure of the clothes treatment device 100 can be simplified.

[0123] As a specific embodiment of the utility model, as shown in Figures 11-12 The second step 1323 is formed in the channel 1322, the second valve piece 1341 is arranged at the second step 1323, the cross-sectional area of the second valve piece 1341 is greater than the cross-sectional area of the channel 1322 at the second step 1323, so that when the fan 131 is turned on, the gas pushes the second valve piece 1341 away from the second step 1323 to open the channel 1322, and when the fan 131 is turned off, the second valve piece 1341 contacts the second step 1323 to close the channel 1322.

[0124] Specifically, the second step 1323 is arranged at the front end of the gas flow in the channel 1322, the second valve piece 1341 is arranged at the side of the second step 1323 away from the fan 131, and the cross-sectional area of the channel 1322 at the second step 1323 is smaller than the cross-sectional area of the second valve piece 1341. In this way, the second valve piece 1341 is not blocked by the second step 1323 when it is blown up by the fresh air generated by the fan 131, which is conducive to smooth flow of the gas. When the second valve piece 1341 is pushed by the pushing force from the air outlet end to the air inlet end of the outlet piece 132, the second step 1323 can also block the second valve piece 1341, the second step 1323 contacts the second valve piece 1341, which can prevent the second valve piece 1341 from being pushed by the reverse force, and can avoid the foam flowing reversely from the gap between the second valve piece 1341 and the second step 1323 into the outlet piece 132, and then to the fan, and then damaging the fan.

[0125] According to Bernoulli's theorem, the larger the cross-sectional area of the channel 1322 is, the smaller the flow rate of the gas is; the smaller the cross-sectional area of the channel 1322 is, the larger the flow rate of the gas is. The cross-sectional area of the channel 1322 at the second step 1323 is small, which can increase the wind speed of blowing the second valve plate 1341, so that the second valve plate 1341 is fully opened, at this time, the flow resistance of the gas is reduced, which can make the gas flow smoothly.

[0126] As a specific embodiment of the utility model, the valve assembly 134 can further include an ear 1342, the ear 1322 is arranged at the second step 1323, the second valve plate 1341 is arranged with a second rotating shaft 1343, the second valve plate 1341 is arranged at the ear 1342 through the second rotating shaft 1343, and the second valve plate 1341 can rotate around the second rotating shaft 1343 under the push of the gas.

[0127] Specifically, the number of ears 1342 is two, the number of second rotating shafts 1343 is two, the ears 1342 are arranged at both sides of the second step 1323 on the upper side inside the outlet piece 132, the second rotating shafts 1343 are arranged at both sides of the top of the second valve plate 1341, and the second rotating shafts 1343 are matched with the ears 1342 to rotatably connect the second valve plate 1341 with the outlet piece 132.

[0128] As a specific embodiment of the utility model, when the number of ears 1342 and second rotating shafts 1343 is one, the ear 1342 is located at the middle position of the top of the outlet piece 132, and the second rotating shaft 1343 is located at the middle position of the top of the second valve plate 1341. In other embodiments, the number of ears 1342 can also be multiple, for example, it can be 3, 4, 5 or 6, and the second rotating shaft 1343 can be matched with the ear 1342.

[0129] As a specific embodiment of the utility model, the ear 1342 can be arranged below a supporting rib 1344 to increase the strength of the ear 1342. Specifically, the supporting rib 1344 is located at the bottom outside of the ear 1342 and is connected with the ear 1342. The supporting rib 1344 is arranged vertically below the ear 1342, which can effectively disperse the stress of the ear 1342, thereby improving the structural strength of the ear 1342.

[0130] As a specific embodiment of the utility model, the outlet piece 132 can further include a first connecting part 1324 connected with the air pipe 133 through the first connecting part 1324. The first connecting part 1324 is located at the air outlet side of the outlet piece 132, the first connecting part 1324 is formed in a cylindrical shape and extends towards the direction of the cylinder body 110, one end of the air pipe 133 is connected with the first connecting part 1324, and the other end extends to the cylinder body 110 and communicates with the inside of the cylinder body 110. Specifically, the first connecting part 1324 is in a cylindrical shape and extends downward from the bottom of the outlet piece 132, when the air pipe 133 is connected with the first connecting part 1324, the air pipe 133 is sleeved on the cylinder in an interference fit, which can stabilize the connection between the air pipe 133 and the outlet piece 132 and improve the structural stability of the clothes treatment device 100.

[0131] As a specific embodiment of the utility model, as shown in Figures 13-16 The clothes treatment device 100 can further include a support assembly 136, and the support assembly 136 is formed with a first mounting part 1361 for mounting the air fan 131. The first mounting part 1361 includes a bottom plate 1362 and a side wall 1363, and the bottom plate 1362 is provided with an air inlet 1364, and the air fan 131 is mounted above the bottom plate 1362 and inside the side wall 1363. When the air fan 131 is started, the gas enters the air fan 131 from the bottom of the air fan 131 through the air inlet 1364.

[0132] Specifically, the outlet piece 132 is fixed on the support piece by screws, and then the rubber air pipe 133 or the corrugated air pipe 133 is connected to the first connecting part 1324 of the outlet piece, and is connected to the inside of the cylinder body 110 through the door seal to achieve the effect of removing the odor in the clothes treatment device 100 and drying the cylinder body 110 and the door seal. The air fan 131 is fixedly installed on the bottom plate 1362 by screws, and the air fan 131 is also connected with the outlet piece 132 and is fixed again through the outlet piece 132 to ensure the stability of the installation of the air fan 131 and improve the structural stability of the fresh air assembly 130.

[0133] The air inlet 1364 of the support assembly 136 is arranged at the bottom plate 1362, the air suction port of the air fan 131 faces downward and is aligned with the air inlet 1364 at the bottom plate 1362, which can have more space to suck fresh air, so that the air volume is moderate but the air pressure is large, which can effectively exhaust the humid gas and odor in the cylinder body 110.

[0134] In other embodiments, the air fan 131 is arranged to suck air from the upper side, and the air suction port of the air fan 131 faces upward. However, due to the presence of the top cover in the clothes treatment device 100, the space above the support assembly 136 is small, and the space for sucking fresh air is small. Therefore, preferably, the air suction port of the air fan 131 is arranged to face downward.

[0135] As a specific embodiment of the utility model, the outlet piece 132 can further include a second connecting part 1325, which is located at the outer periphery of the air inlet side of the outlet piece 132. The side wall 1363 of the support assembly 136 is provided with a second mounting part 1365, which is located on both sides of the outlet side of the fan 131. The second connecting part 1325 is connected with the second mounting part 1365 through fasteners, thereby connecting the outlet piece 132 with the support assembly 136.

[0136] Specifically, as shown in Figure 14 and Figure 16 , the second connecting part 1325 is formed by extending the housing 1321 of the air inlet side of the outlet piece 132 to the outside of the channel 1322, and the second mounting part 1365 is generally square. The second connecting part 1325 is connected with the second mounting part 1365 through fasteners such as screws, so that the outlet piece 132 can be stably connected with the support assembly 136, thereby improving the structural stability of the clothes treatment device 100.

[0137] As a specific embodiment of the utility model, as shown in Figure 15 and Figure 16 , the fresh air assembly 130 can further include a negative ion generating piece 135, which includes a mounting groove 1351 and an ion generating end 1352. The support assembly 136 further includes a third mounting part 1366 for mounting the negative ion generating piece 135, which is located below the bottom plate 1362. The third mounting part 1366 further includes a mounting protrusion 1367, which cooperates with the mounting groove 1351 and is connected with each other through fasteners to mount the negative ion generating piece 135 at the third mounting part 1366. The third mounting part 1366 is provided with a through hole 1368 for the ion generating end 1352 to pass through, and the ion generating end 1352 is directed towards the air inlet 1364 of the bottom plate 1362.

[0138] Specifically, the mounting groove 1351 of the negative ion generating piece 135 is located outside the side wall 1363 of the first mounting part 1361, and the two ion generating ends 1352 respectively pass through the through hole 1368 on one third mounting part 1366, so that the negative oxygen ions generated by the ion generating end 1352 of the negative ion generating piece 135 can enter the drum 110 through the outlet piece 132 and the air duct 133 together with the fresh air, which can effectively remove the odor in the drum 110, freshen the air, and also remove static electricity on the clothes.

[0139] More specifically, the negative ion generating component 135 is located on the side of the fan 131 away from the outlet component 132 and on the lower side of the support assembly 136, so that the gas just entering the outlet component 132 is full of negative ions, which purifies the gas just entering the air duct 133.

[0140] In this embodiment, the negative ion generating component 135 not only sterilizes the air just entering the fresh air assembly 130, but also makes the gas in the fresh air assembly 130 carry negative ions to have the effect of sterilization and odor removal. When the gas carrying negative ions flows into the barrel 110 through the air outlet end of the air duct 133, the negative ions combine with the clothes to sterilize and remove odor, thereby improving the practicality of the clothes treatment device 100.

[0141] The matching application of the negative ion generating component 135 and the fresh air can not only improve the effect of the fresh air, but also can make the negative ions quickly enter the barrel, achieve the effect of removing static electricity and reducing wrinkles of the clothes, and improve the effect of the fresh air.

[0142] In this embodiment, the negative ion generating component 135 is arranged at the air inlet 1364 close to the bottom plate 1362, so that the negative ion component is close to the air suction port of the fan 131. When the valve assembly 134 closes the outlet component 132, the inside of the outlet component 132 is completely closed, which can prevent the detergent foam from flowing back into the fan 131 and the negative ion generating component 135 when the clothes treatment device 100 is running, thereby effectively reducing the risk of overflow. It can also effectively prevent the high-humidity environment in the barrel 110 from causing the negative ion generating component 135 to fail.

[0143] The conventional clothes treatment device 100 places the negative ion component at the air outlet of the fresh air structure or directly inserts the brush into the barrel 110, which has the risk of water entering and causing failure and electric shock. In contrast, the design of this embodiment can make the negative ions generated by the ion generating end 1352 enter the barrel 110 along with the fresh air flow generated by the fan 131, and can also avoid the risk of water entering and causing failure and electric shock of the negative ion generating component 135.

[0144] In other embodiments, the negative ion generating component 135 can also be arranged on the upper side of the support assembly 136, but due to the presence of the top cover in the clothes treatment device 100, the space above the support assembly 136 is small. Therefore, preferably, the negative ion generating component 135 is arranged on the lower side of the support assembly 136.

[0145] As a specific embodiment of the utility model, the laundry treatment device 100 can further include a crossbeam 1373, which can be arranged at the rear side of the control panel 113. The crossbeam 1373 includes a first recess 1374. The support assembly 136 further includes a fourth mounting portion 1369, which is structured to cooperate with the first recess 1374 and is connected with the crossbeam 1373 by fasteners.

[0146] Specifically, the crossbeam 1373 extends in the horizontal direction, and the first recess 1374 is located at the upper side of the crossbeam 1373. The fourth mounting portion 1369 overlaps the first recess 1374 from above and is fixedly connected with the first recess 1374 by screws or other fasteners. The crossbeam 1373 can connect various parts of the laundry treatment device 100, such as the front and rear side plates or the upper and lower parts, to form a more compact whole and enhance the overall rigidity and stability of the laundry treatment device 100, so that it can better withstand centrifugal force and other forces generated by the rotation of the drum 110 and reduce the vibration and displacement of the entire machine. In this embodiment, the support assembly 136 is mounted on the crossbeam 1373, which can improve the structural stability of the laundry treatment device 100.

[0147] As a specific embodiment of the utility model, the detergent box 120 of this embodiment includes a protrusion 121. The support assembly 136 further includes a fifth mounting portion 137, which forms a second recess 1371 that cooperates with the protrusion 121, and the protrusion 121 is connected with the second recess 1371 by fasteners, thereby connecting the support assembly 136 with the detergent box 120.

[0148] Specifically, the detergent box 120 of the laundry treatment device 100 is located behind the crossbeam 1373, and the protrusion 121 is located on the outer side of the detergent box 120. The size of the protrusion 121 matches the second recess 1371, and after the protrusion 121 extends into the second recess 1371, the protrusion 121 is fixedly connected with the second recess 1371 by screws or other fasteners, so that the support assembly 136 is stably mounted on the detergent box 120.

[0149] As a specific embodiment of the utility model, the support assembly 136 can be fixed on the crossbeam 1373 alone, or on the detergent box 120 alone, or on both the crossbeam 1373 and the detergent box 120.

[0150] As a specific embodiment of the utility model, the support assembly 136 is stably connected with the crossbeam 1373 and the detergent box 120 by fasteners, and is convenient to install. In other embodiments, the support assembly 136 is provided with fixing holes and positioning holes, which can improve the stability and convenience of the installation of the support assembly 136 with the crossbeam 1373 and the detergent box 120.

[0151] The structure design that the support assembly 136 is fixed on the cross beam 1373 and the detergent box 120 at the same time can make the fan 131 closer to the air outlet end of the fresh air assembly 130, the pipeline is shorter, the bending is less, the flow resistance can be effectively reduced, and the air outlet amount is increased compared with the traditional design.

[0152] The support assembly 136 is fixed on the cross beam 1373 and the detergent box 120 respectively, can fix the outlet piece 132, the fan 131 and the negative ion module at the same time, realize the integrated design, and be convenient for installation and production.

[0153] As a specific embodiment of the utility model, as shown in Figure 15 and Figure 16 As shown in the drawings, the support assembly 136 can also include a reinforcing rib 1372, which is arranged at the third mounting portion 1366, the fourth mounting portion 1369 and the fifth mounting portion 137 to increase the strength of the third mounting portion 1366, the fourth mounting portion 1369 and the fifth mounting portion 137, thereby improving the connection stability between the support assembly 136 and the negative ion generating piece 135, the support assembly 136 and the cross beam 1373, and the support assembly 136 and the detergent box 120.

[0154] During the operation of the clothes treatment device 100, some parts may bear relatively concentrated stress, for example, the connection between the support assembly 136 and the cross beam 1373. The reinforcing rib 1372 can disperse these concentrated stresses to a larger area, reduce the local stress level, avoid fatigue damage or cracks of the components at the stress concentration, and improve the reliability and stability of the clothes treatment device 100.

[0155] As a specific embodiment of the utility model, the cylinder body 110 can include an inlet 111 and a cylinder wall 112, the air pipe 133 is connected with the cylinder wall 112, and the connection is close to the inlet 111. It can be understood that the cylinder wall 112 is the shell of the cylinder body 110, the inlet 111 is a clothes feeding port for feeding clothes, the inlet 111 is located on the front side of the cylinder body 110 and communicates with the internal space formed by the cylinder wall 112.
