Description

Technical Field

[0001] The present invention relates to the technical field of fabric treatment equipment, and in particular to an air induction module, a fabric treatment equipment and a fresh air control method thereof. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the functions and performances of household appliances. As one of the commonly used household appliances in the family, fabric treatment equipment such as washing machines is constantly upgraded and improved in its functions.

[0003] After the traditional washing machine completes the washing program, it usually stops running automatically, and the user needs to manually take out the fabric. However, if the user forgets to take out the fabric in time, especially in the hot and humid environment in summer, the fabric is prone to mildew and odor, which affects the user's wearing experience and health.

[0004] At present, some washing machines on the market adopt the design of automatically opening the door after washing the fabric, and reduce the odor of the fabric through natural ventilation. There are also some washing machines that reduce the odor accumulation by intermittently rotating the drum at a low speed. However, the above design methods all have certain limitations. Among them, the washing machines with automatically opening the door after washing the fabric have the following problems: First, the ventilation effect is limited. That is, although the automatically opening door design can improve the ventilation inside the washing machine to a certain extent, due to the limitations of natural ventilation, the actual effect is not ideal. Second, the air circulation in the drum is uneven. That is, the fabrics inside the washing machine are usually stacked at the bottom, and the air flow in the upper part is difficult to reach the bottom, resulting in the fabrics at the bottom still being wet and prone to odor. Third, it is highly dependent on the environment. That is, the effect of natural ventilation is greatly affected by external environments such as air humidity and temperature, and it cannot ensure effective ventilation in various environments. In addition, the method of intermittently rotating the drum at a low speed is only for the internal circulation of the washing machine, and such washing machines have no ventilation setting, and the generation of odor for a long time cannot be avoided either. Summary of the Invention

[0005] In view of this, the present invention provides an air induction module, a fabric treatment equipment and a fresh air control method thereof to solve the problem that the existing fabric treatment equipment cannot well improve the ventilation condition inside the fabric treatment drum, resulting in the fabrics after washing affecting the user's wearing experience and health.

[0084] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0085] As Figures 1 to 6 shown, an exemplary embodiment of the present invention provides an air induction module 100, which can be applied to a fabric processing device 10 to introduce fresh air into a fabric processing cylinder 11 in the fabric processing device 10, so as to improve the ventilation condition of the fabric after laundry and prevent the fabric from generating peculiar smell due to long-term accumulation.

[0086] Among them, the fabric processing device may include, but is not limited to, a washing machine, and the washing machine may include, but is not limited to, an integrated washing and care machine, a washing and drying integrated machine, etc. For example, the washing machine may be a drum washing machine or a pulsator washing machine with drying or washing and care functions. Of course, the washing machine may also be other types of fully automatic washing machines.

[0087] In this example and the following examples, the fabric processing device is described by taking a washing machine as an example.

[0088] Among them, the air induction module 100 includes: an air induction box 110, a damper assembly 120, and an air induction member 130.

[0089] A fresh air duct 111 is formed inside the air induction box 110. An air inlet 11a and an air outlet 11b are respectively formed at both ends of the fresh air duct 111. The air inlet 11a can be controlled to introduce air from the outside, that is, the air inlet 11a is used to introduce fresh air from the external environment, and the air outlet 11b conveys the fresh air passing through the fresh air duct 111 into the fabric processing cylinder 11.

[0090] The air induction box 110 can provide an installation and working space for the air induction member 130 and the damper assembly 120. So that the air induction member 130 can generate an air flow in a relatively enclosed and stable environment, and at the same time, the damper assembly 120 can also accurately play a role at the position of the air inlet 11a, thereby realizing the overall function of the air induction module 100.

[0091] In some embodiments, the damper assembly 120 includes a damper 121. The damper 121 is disposed at the air inlet 11a in an openable and closable manner for opening and closing the air inlet 11a.

[0092] The air induction member 130 is disposed inside the fresh air duct 111 and is used to provide power for introducing fresh air into the fresh air duct 111 after the fresh air program of the fabric processing device 10 is started. That is, the air induction member 130 can form a flowing fresh air flow in the fresh air duct 111. Among them, the air induction member 130 can adopt various ways to form the fresh air flow. For example, the air induction member 130 can be a rotating structure similar to a fan, and the high-speed rotation of the blades drives the air to flow. The air induction member 130 can also be a structure using the principle of air pressure difference, and different air pressure regions are created to cause the air to flow from the high-pressure region to the low-pressure region to form an air flow.

[0093] In addition, the air induction member 130 can also directly adopt a fan assembly, such as a centrifugal fan assembly or an axial flow fan assembly, etc. to form an air flow, so as to reduce the number of parts and improve the reliability of the operation of the fresh air program.

[0094] Among them, the damper 121 and the air induction member 130 are also configured to: when the air induction member 130 is in a non-working state, the damper 121 automatically closes the air inlet 11a and maintains the closed state to prevent fresh air from flowing into the fresh air duct 111.

[0095] Moreover, when the air guiding member 130 is in the working state, the air damper 121 can automatically open the air inlet 11a under the air guiding action of the air guiding member 130 and maintain the open state, so that fresh air can flow into the fresh air duct 111.

[0096] In this example, by the mutual cooperation of the air damper 121 in the air damper assembly 120 and the air guiding member 130, it is possible to realize automatic control and introduce fresh air when the fabric treatment cylinder 11 needs air guiding, and can automatically close the air inlet when fresh air is not required, so as to prevent external dust and sundries from entering the interior of the fabric treatment cylinder, effectively simplifying the control mechanism for introducing fresh air and improving the reliability and durability of the system.

[0097] In one example, the air damper assembly 120 includes an air damper 121 and an elastic member 122. Among them, the air damper 121 can be rotatably arranged at the position of the air inlet 11a. After the air guiding member 130 is started, a fresh air flow is formed in the fresh air duct 111. During the flow of the fresh air flow, the air pressure on the side of the air damper 121 facing the air guiding member 130 decreases, and the atmospheric pressure of the external environment pushes the air damper 121 to rotate. At this time, the air damper 121 rotates to open the air inlet 11a and changes the elastic potential energy of the elastic member 122. When the air guiding member 130 stops operating, the fresh air flow in the fresh air duct 111 stops flowing, and under the action of the elastic potential energy of the elastic member 122, the air damper 121 is driven to rotate in the reverse direction to close the air inlet 11a.

[0098] That is to say, the rotation action of the air damper 121 is closely related to the elastic potential energy of the elastic member 122. For example, when the air guiding member 130 starts to work and a fresh air flow is formed in the fresh air duct 111, the fresh air flow generates a force on the air damper 121, causing the air damper 121 to rotate to open the air inlet 11a. During the rotation of the air damper 121, the elastic potential energy of the elastic member 122 changes, that is, the elastic member 122 stores a certain amount of energy. When the air guiding member 130 stops working, that is, when the fresh air flow in the fresh air duct 111 stops flowing, the elastic potential energy of the elastic member 122 begins to play a role. Under the action of the elastic potential energy, the air damper 121 will rotate to close the air inlet 11a. Based on this, it is possible to effectively prevent external impurities, dust or unnecessary air from entering the air guiding module 100 and the fabric treatment cylinder 11. When the fabric treatment device stops working, closing the air inlet 11a can protect the internal environment of the device, avoid dust and other pollutants from contaminating the fabric or other components inside the device, and also helps to maintain the air pressure stability inside the device.

[0099] It should be noted that the number of air doors 121 can be multiple, and an elastic member 122 is provided in each air door 121. Among them, flexible sealing strips (not shown in the figure) are provided in the gaps between adjacent air doors 121 and between the air door 121 and the air inlet 11a to prevent air leakage from these gaps when the air door 121 closes the air inlet 11a.

[0100] In another example, the top of the air door 121 can be rotatably provided at the air inlet 11a. One end of the bottom of the air door 121 is connected to one end of the elastic member 122, and the other end of the elastic member 122 can be connected to the inside of the fresh air duct 111. Among them, the initial position of the air door 121 is to close the air inlet 11a. Based on this, when the air guiding member 130 is opened, the air pressure on the side of the air door 121 facing the air guiding member 130 decreases. Under the action of the atmospheric pressure of the external environment, the bottom of the air door 121 is pushed to deflect in the direction of the air guiding member 130, thereby opening the air inlet 11a. At this time, the elastic member 122 can be compressed to have a certain elastic potential energy. When the air guiding member 130 is controlled to stop operating, under the action of the self-gravity of the air door 121 and in cooperation with the elastic potential energy of the elastic member 122, the air inlet 11a is automatically closed.

[0101] It should be noted that in yet another example, the elastic member 122 can also be not provided. When the air guiding module 100 is installed in place, taking a drum washing machine as an example, the air inlet 11a of the air guiding module 100 can be horizontally arranged. When the air guiding member 130 is opened, the air pressure on the side of the air door 121 facing the air guiding member 130 decreases. Under the action of the atmospheric pressure of the external environment, the bottom of the air door 121 is pushed to deflect in the direction of the air guiding member 130, thereby opening the air inlet 11a. When the air guiding member 130 is controlled to stop operating, it returns to its original position under the action of the self-gravity of the air door 121, thereby automatically closing the air inlet 11a.

[0102] In some other embodiments, the air door assembly 120 is composed of an air door 121 and an elastic member 122. The air door 121 is disposed at the air outlet 11b in an openable and closable manner for opening and closing the air outlet 11b. One end of the elastic member 122 is connected to the air door 121, and the other end of the elastic member 122 is connected to the air guiding box 110.

[0103] The air guiding member 130 is disposed at the position of the air inlet 11a and is used to introduce fresh air into the fresh air duct 111 after the fresh air program of the fabric processing device 10 is started. That is, the air guiding member 130 can form a circulating fresh air flow in the fresh air duct 111. Among them, the air guiding member 130 can form a fresh air flow in various ways. For example, the air guiding member 130 can be a rotating structure similar to a fan, and the high-speed rotation of the blades drives the air to flow. The air guiding member 130 can also be a structure using the principle of air pressure difference, and the air is made to flow from the high-pressure area to the low-pressure area to form a flow by creating different air pressure areas.

[0104] In addition, the air guiding member 130 can also directly adopt a fan assembly, such as a centrifugal fan assembly or an axial flow fan assembly, etc. to form a flow, so as to reduce the number of parts and improve the reliability of the operation of the fresh air program.

[0105] Among them, the air door 121, the elastic member 122 and the air guiding member 130 are also configured such that: before the air guiding member 130 is started, or when it is closed after being started, the air door 121 can automatically close the air outlet 11b under the action of the elastic potential energy of the elastic member 122, or under the action of the gravity of the air door 121 itself, so as to prevent the fresh air from flowing out of the fresh air duct 111.

[0106] And, after the air guiding member 130 is started, the air door 121 can automatically open the air outlet 11b under the air guiding action of the air guiding member 130, so that the fresh air can flow out of the fresh air duct 111.

[0107] In one example, the air door 121 can be rotatably disposed at the position of the air outlet 11b. After the air guiding member 130 is started, a fresh air flow is formed in the fresh air duct 111. During the flow of the fresh air flow, the air pressure on the side of the air door 121 facing the air guiding member 130 increases, thereby pushing the air door 121 to rotate. At this time, the air door 121 rotates to open the air outlet 11b and changes the elastic potential energy of the elastic member 122. When the air guiding member 130 stops operating, the fresh air flow in the fresh air duct 111 stops flowing, and the elastic potential energy of the elastic member 122 drives the air door 121 to rotate in the reverse direction to close the air outlet 11b.

[0108] That is to say, the rotation of the air damper 121 is closely related to the elastic potential energy of the elastic member 122. For example, when the air guiding member 130 starts to work and a fresh air flow is formed in the fresh air duct 111, the fresh air flow generates a force on the air damper 121, causing the air damper 121 to rotate and open the air outlet 11b. During the rotation of the air damper 121, the elastic potential energy of the elastic member 122 changes, that is, the elastic member 122 stores a certain amount of energy. When the air guiding member 130 stops working, that is, when the fresh air flow in the fresh air duct 111 stops flowing, the elastic potential energy of the elastic member 122 begins to take effect. Under the action of the elastic potential energy, the air damper 121 will rotate to close the air outlet 11b. Based on this, it is possible to prevent impurities, dust, or unnecessary air from the outside from entering the fabric treatment cylinder 11. When the fabric treatment device stops working, closing the air outlet 11b can protect the internal environment of the device, avoid dust and other pollutants from contaminating or damaging the fabric or other components inside the device, and also helps to maintain the air pressure stability inside the device.

[0109] It should be noted that the number of air dampers 121 can be multiple, and an elastic member 122 is provided in each air damper 121. Among them, flexible sealing strips (not shown in the figure) are provided at the gaps between adjacent air dampers 121 and at the gap between the air damper 121 and the air inlet 11a to prevent air leakage from these gaps when the air damper 121 is in the state of closing the air outlet 11b.

[0110] In another example, the top of the air damper 121 can be rotatably arranged at the air outlet 11b, one end of the bottom of the air damper 121 is connected to one end of the elastic member 122, and the other end of the elastic member 122 can be connected to the inside of the fresh air duct 111. Among them, the initial position of the air damper 121 is to close the air outlet 11b. Based on this, when the air guiding member 130 is turned on, the air pressure on the side of the air damper 121 facing the air guiding member 130 increases, thereby pushing the bottom of the air damper 121 to deflect away from the air outlet 11b, thus opening the air outlet 11b. At this time, the elastic member 122 can be stretched to have a certain amount of elastic potential energy. When the air guiding member 130 is controlled to stop operating, under the action of the self-gravity of the air damper 121 and in cooperation with the elastic potential energy of the elastic member 122, the air outlet 11b is automatically closed.

[0111] It should be noted that in another example, the elastic member 122 may not be provided. Taking the drum washing machine as an example, after the air guiding module 100 is installed in place, the air outlet 11b of the air guiding module 100 may be set horizontally. When the air guiding member 130 is turned on, the air pressure on the side of the air door 121 facing the air guiding member 130 increases, thereby pushing the bottom of the air door 121 to deflect away from the air guiding member 130, thus opening the air outlet 11b. When the air guiding member 130 is controlled to stop operating, it returns to its original position under the action of the self-gravity of the air door 121, thereby automatically closing the air outlet 11b.

[0112] It should be noted that the air guiding member 130 can convey fresh air from the outside to the fabric treatment cylinder 11. The air guiding module 100 can be used for the ventilation condition of the fabric after the fabric washing is completed. In some fabric treatment devices 10 with a high-temperature washing function (such as a drum washing machine) during the washing process, the washing water will be heated. Especially when certain special functions such as the ironing function are used, the temperature of the washing water can be as high as seventy or eighty degrees. At this time, due to the good heat conduction performance of the outer cylinder of the fabric treatment cylinder 11, the heat of the washing water will be conducted to the air guiding box 110 through the outer wall of the outer cylinder, so that the temperature of the air in the air guiding box 110 or the air flowing through the air guiding box 110 will be higher than the outside air temperature. That is to say, the above-mentioned fabric treatment device 10 with a high-temperature washing function can appropriately heat the fresh air through the air guiding module 100, thereby increasing the temperature of the fresh air entering the fabric treatment cylinder 11. When the temperature of the fresh air is relatively high, it is more conducive to the sterilization of the fabric after washing. That is, by using the heat generated by heating the washing water during the washing process of the drum washing machine, the sterilization effect of the fabric treatment device 10 can be further improved, the energy consumption can be effectively reduced, and the fabric treatment device 10 is more energy-saving.

[0113] At the same time, based on the structure of the above-mentioned air guiding module 100, it can avoid the problems of fabric dampness and peculiar smell caused by the limited natural ventilation effect. The continuous introduction of fresh air effectively controls the humidity inside the fabric treatment cylinder 11, thereby prolonging the service life of the fabric and improving the user experience.

[0114] In some embodiments, a plurality of automatic rubber air valve structures (not shown in the figure) may also be provided at the position of the air inlet 11a. When the air guiding member 130 (i.e., the fan 131) is turned on, under the action of negative pressure, that is, the flow of the air current, the automatic rubber air valve structure at the air inlet 11a opens toward the fan 131 side, realizing the purpose of introducing fresh air from the outside into the fresh air duct 111. When the air guiding member 130 stops operating, the automatic rubber air valve structure closes under the action of gravity to close the air inlet 11a, so as to ensure that dirty or humid air from the outside cannot enter the fabric treatment cylinder 11 through the air inlet 11a.

[0115] In some embodiments, the air draft component 130 is controlled to be able to be turned on or off in the fresh air program. Among them, the air damper 121 is controlled to be linked with the air draft component 130, so that the air draft component 130 can be linked with the process of the fresh air program. Furthermore, in cooperation with the air damper assembly 120, it can achieve automatic control and introduction of fresh air when the fabric treatment cylinder 11 needs air draft, and can automatically close the air inlet when fresh air is not required, so as to prevent external dust and sundries from entering the interior of the fabric treatment cylinder, effectively simplifying the control mechanism for fresh air introduction and improving the reliability and durability of the system. It should be noted that the linkage between the air damper 121 and the air draft component 130 during the operation of the fresh air program can be referred to the description of the air draft module 100 above or below, and will not be elaborated here.

[0116] In addition, the air draft component 130 can also be controlled to be able to be turned on or off during any one process or all processes such as the fresh air program, the environmental parameters inside the fabric treatment cylinder, the environmental parameters outside the fabric treatment cylinder, and the operating parameters of the fabric treatment cylinder. Among them, the air damper 121 is controlled to be linked with the air draft component 130.

[0117] For example, the opening and closing process of the air draft component 130 in the fresh air program can be referred to any of the above embodiments. In addition, in the early stage of the drying program when the fabric treatment equipment 10 is running, because the humidity inside the fabric treatment cylinder 11 is relatively high, such as exceeding 75% or more, the air draft component 130 can be passively opened, and in cooperation with the air permeable pipe 13 provided on the fabric treatment cylinder 11, the air with relatively high humidity can be discharged through the air permeable pipe 13, thereby accelerating the process of the drying program and improving the drying efficiency.

[0118] Moreover, when the external environmental parameters of the fabric treatment cylinder 11, such as the air humidity, are relatively high, such as exceeding 75% or more, the air draft component 130 is passively closed to prevent the air with relatively high humidity in the external environment from entering the fabric treatment cylinder 11 after the washing program or drying program has been completed (at this time, the fabric has not been taken out).

[0119] Or, during the operation of the fabric treatment cylinder 11, when the temperature inside it is relatively high (such as during high-temperature washing) or the humidity is relatively high (such as in the early stage of the drying program), the air draft component 130 can be passively opened or closed, so that the temperature and humidity inside the fabric treatment cylinder 11 can quickly drop to an appropriate range, improving the processing efficiency of the fabric. On the other hand, when the operating load of the fabric treatment cylinder 11 is relatively large, which may cause relatively serious heating when other components inside the fabric treatment equipment 10 are running, at this time, the air draft component 130 can be passively opened to introduce fresh air into the fabric treatment cylinder 11, and then in cooperation with the drying channel, appropriately cool the above-mentioned components with serious heating, or cool the interior of the fabric treatment cylinder 11, and use the heat conduction effect to appropriately cool the above-mentioned components with serious heating, so as to ensure the normal operation of the fabric treatment equipment 10.

[0120] As Figures 1 to 6 shown, in some embodiments, in order to enable the air damper 121 to rotate under the action of air flow, a through hole 123 perpendicular to the height direction of the air draft box 110 may be formed in the air damper 121, and a rotating shaft 124 is arranged in the through hole 123. That is to say, when there is air flow in the air draft box 110, the rotation of the air damper 121 can be realized by using the rotating shaft 124, that is, the air damper 121 rotates around the rotating shaft 124, so that the air inlet 11a can be opened.

[0121] Among them, the through hole 123 may be arranged on the central axis of the air damper 121. Alternatively, the through hole 123 may also be arranged beside the air damper 121, that is, deviate from the central axis of the air damper 121. For example, according to the specific installation position and installation space of the air draft module 100, the through hole 123 may be arranged at a certain distance to the left or right of the central axis of the air damper 121, so that the air damper 121 and the air draft member 130 cooperate with each other, and under the action of the elastic potential energy of the elastic member 122, the air inlet 11a can be opened or closed.

[0122] The elastic member 122 is sleeved on the rotating shaft 124, and both ends of the elastic member 122 are respectively connected to the air damper 121 and the rotating shaft 124, so as to form elastic compression on the elastic member 122 when the air damper 121 rotates around the rotating shaft 124. It should be noted that the above elastic compression can store energy and play a buffering role to a certain extent. For example, when the air damper 121 rotates rapidly due to an external force, the compression of the elastic member 122 can absorb a part of the energy to prevent the air damper 121 from excessive displacement. At the same time, the elastic compression can also release energy at an appropriate time to assist the air damper 121 to return to its original position or reach a new equilibrium state.

[0123] As Figures 1 to 6 shown, in some embodiments, the center of the rotating shaft 124 is misaligned with the center of the air damper 121, so that under the relatively small air draft action of the air draft member 130, the longer side of the air damper 121 can be quickly opened to reduce the loss of air volume.

[0124] It should be noted that the center of the rotating shaft 124 does not coincide with the center of the air damper 121, that is, the rotation characteristics of the air damper 121 when rotating around the rotating shaft 124 are quite different from those when they are coaxial. When they are coaxial (that is, the center of the rotating shaft 124 coincides with the center of the air damper 121), the rotation of the air damper 121 is relatively stable, and the center of gravity coincides with or is close to the center of rotation. However, in the case of misalignment, the center of gravity of the air damper 121 deviates from the center of rotation, which will cause an imbalance of centrifugal force during the rotation process. This unbalanced centrifugal force enables the air damper 121 to rotate under a relatively small acting force, thereby reducing the rated rotation power of the air draft member 130 in the fresh air duct 111 and reducing energy consumption.

[0125] As Figures 1 to 6 shown, in some embodiments, the rotating shaft 124 includes a first section 1241, a connecting section 1242, and a second section 1243 connected in sequence. Among them, the top end of the first section 1241 and the lower end of the second section 1243 are fixedly connected to the corresponding positions of the air inlet 11a respectively.

[0126] A sleeve (not shown in the figure) is provided at the position of the connecting section 1242 of the rotating shaft 124. The elastic member 122 is disposed within the sleeve, and both ends of the elastic member 122 extend out of the sleeve and are respectively connected to the air damper 121 and the first section 1241 or the second section 1243.

[0127] The sleeve provides a specific accommodation space for the elastic member 122, enabling the elastic member 122 to have a relatively stable installation position inside the through hole 123, which helps to protect the elastic member 122 from being interfered by external factors (such as dust, impurities, or accidental collisions with other components). At the same time, the sleeve can also play a certain guiding role for the elastic member 122 to ensure that the elastic member 122 deforms along a specific direction when being compressed and stretched, thereby ensuring the stability of the mechanical properties of the entire air damper assembly 120.

[0128] Among them, after both ends of the elastic member 122 extend out of the sleeve, one end can be connected to the corresponding position of the air damper 121, and the other end can be connected to the first section 1241 or the second section 1243. Thus, when the air damper 121 rotates around the rotating shaft 124 under the action of air flow, the elastic potential energy of the elastic member 122 can be changed. For example, a certain elastic compression can be formed; then, when the air flow stops, the elastic compression of the elastic member 122 is utilized to enable the air damper 121 to rotate reversely around the rotating shaft 124, thereby closing the air inlet 11a.

[0129] As Figures 1 to 6 shown, in some embodiments, a limiting stop 1244 is provided on the first section 1241, and one end of the elastic member 122 abuts against the limiting stop 1244 to form a restriction on this end of the elastic member 122, preventing relative movement of this end of the elastic member 122 when the air damper 121 rotates.

[0130] The other end of the elastic member 122 is connected to the air damper 121.

[0131] Alternatively, in another example, the above-mentioned limiting stop 1244 can also be provided on the second section 1243.

[0132] Among them, in order to achieve the fixed connection between the limiting stop 1244 and the elastic member 122, a jack can be provided on the limiting stop 1244, and one end of the elastic member 122 can be directly inserted into the above-mentioned jack, thereby forming a restriction on this end of the elastic member 122.

[0133] As Figures 1 to 6 shown, in some embodiments, the elastic member 122 includes at least, but is not limited to, a helical compression spring. When the helical compression spring is subjected to an external force, such as when one end of the elastic member 122 is rotated by the rotation of the air damper 121, it stores energy and can quickly return to its original shape after the external force is removed. Moreover, the above-mentioned helical compression spring can also be flexibly designed according to the specific requirements of the air damper assembly 120, so that the elastic member 122 can effectively adapt to different air guiding members 130, rotating shafts 124, etc. Alternatively, the parameters of the helical compression spring can also be customized according to the size of the internal space of the sleeve and the required elastic coefficient.

[0134] As Figures 1 to 6 shown, in some embodiments, the air guiding member 130 includes a fan 131. The fan 131 can generate an air flow through the rotation of its impeller, thereby realizing the function of air guiding. The impeller of the fan 131 enables air to be effectively sucked into the air inlet 11a and discharged along a specific direction.

[0135] The number of the fans 131 can be multiple, and the multiple fans 131 are arranged at intervals along the width direction of the air guiding box 110. The arrangement of the multiple fans 131 can increase the total air guiding volume and meet a greater air guiding demand. Arranging at intervals along the width direction helps to make the air guiding effect more uniform within the width range of the entire air guiding box 110.

[0136] The multiple fans 131 form an efficient transmission method through the linkage of the transmission belt 132. The driving motor 133 drives the transmission belt 132 to rotate. Since the transmission belt 132 is connected to the multiple fans 131, the multiple fans 131 can be rotated synchronously to ensure that the working states of the respective fans 131 are coordinated.

[0137] The above-mentioned linkage method can effectively improve the coordination and stability of the entire air guiding module 100. Compared with the method of separately equipping each fan 131 with a driving motor 133, linking the multiple fans 131 through the transmission belt 132 can reduce costs and reduce the complexity of the system. The rotation speeds of all the fans 131 are controlled by the same driving motor 133 through the transmission belt 132, so it is easier to adjust and maintain the entire air guiding module 100. At the same time, due to the synchronous rotation of the respective fans 131, the vibration and noise of the entire air guiding module 100 will be relatively small, improving the reliability and service life of the air guiding module 100.

[0138] It should be noted that multiple fans 131 can be fixed by the same mounting rod 134. The mounting rod 134 can extend along the width direction of the air induction box 110, and both ends of the mounting rod 134 can be fixedly connected to the inner wall of the fresh air duct 111 respectively, so as to complete the fixation of multiple fans 131 on the same mounting rod 134 at the same time.

[0139] Among them, the above-mentioned mounting rod 134 can also pass through the air guiding members 140 on both sides of any fan 131 in sequence. In one example, the mounting rod 134 can be integrally formed with multiple air guiding members 140 to reduce the design and manufacturing difficulty of the air door assembly 120.

[0140] Such as Figures 1 to 6 As shown, in some embodiments, the air induction module 100 further includes an air guiding member 140, and the air guiding member 140 is located beside the fan 131. Among them, a wind guiding surface 141 is formed on the side wall of the air guiding member 140 facing the fan 131, and the wind guiding surface 141 is configured to: increase the flow velocity of the fresh air flow.

[0141] The fan 131 is mainly responsible for generating air flow, while the air guiding member 140 beside the fan 131 can timely guide and optimize the fresh air flow generated by the fan 131, that is, increase the flow velocity of the fresh air flow. When the fresh air flow passes through the wind guiding surface 141, the wind guiding surface 141 will exert a certain constraining and guiding effect on the fresh air flow, similar to concentrating the fresh air flow in a specific air duct, making the flow of the fresh air flow smoother, thereby increasing the flow velocity. For example, the wind guiding surface 141 can adopt a design similar to a streamline shape to reduce the resistance of the fresh air flow during the flowing process, and further increase the flow velocity of the fresh air flow.

[0142] Alternatively, the flow velocity of the fresh air flow can also be increased by changing the cross-sectional area of the air guiding path. Among them, an air guiding member 140 can be provided on both sides of the fan 131. In this way, a wind guiding surface 141 is formed on both sides of the fan 131, and then through the cooperation among the three, a flow path for the fresh air flow to flow through is formed within the area enclosed by the top wall and the bottom wall of the fresh air duct 111. Among them, the cross-sectional area of the front side of the flow path can be larger than that of the rear side, and at the same time, in cooperation with the design of the wind guiding surface 141 similar to a streamline shape, the flow velocity of the fresh air flow can be effectively increased.

[0143] Such as Figure 7 And refer to Figures 1 to 6As shown, in some embodiments, when the number of fans 131 is multiple, a wind guiding member 140 is disposed between adjacent fans 131. There may be slight differences in the air flow characteristics generated by each fan 131. By disposing the wind guiding member 140 between adjacent fans 131, it can be ensured that the fresh air flow generated by each fan 131 can be guided in the expected manner, avoiding interference between the air flows generated by different fans 131.

[0144] Wind guiding surfaces 141 are formed on both side walls (the side walls opposite to the fans 131) of the wind guiding member 140. This enables the wind guiding member 140 to guide the fresh air flow from two directions. Regardless of the direction of the fresh air flow, it can be effectively guided and optimized by the wind guiding member 140. This design of the double-sided wind guiding surface 141 increases the versatility and adaptability of the wind guiding member 140. In the actual air intake module 100, the flow direction of the fresh air flow may be relatively complex, and the double-sided wind guiding surface 141 can handle the fresh air flow from different angles, ensuring that the fresh air flow can be reasonably guided when passing through the wind guiding member 140, and improving the adaptability of the entire air intake module 100 to different working conditions.

[0145] Specifically, the wind guiding surface 141 has a recessed portion 141a that recesses in a direction away from the fan 131, so as to better control the flow path and flow rate of the fresh air flow. Among them, the shape of the recessed portion 141a can change the curvature of the wind guiding surface 141, and when the fresh air flow passes through the recessed portion 141a, it will be affected by the shape of the recessed portion 141a. For example, the recessed portion 141a can be designed to be a fresh air duct similar to a tapered shape, so that the fresh air flow will be accelerated when passing through.

[0146] The influence of the recessed portion 141a on the fresh air flow is not only acceleration, but also includes the adjustment of the pressure and direction of the fresh air flow. According to the principle of fluid mechanics, the presence of the recessed portion 141a will change the pressure distribution around the fresh air flow, causing the pressure inside the recessed portion 141a to decrease, thereby further increasing the flow rate. At the same time, the shape of the recessed portion 141a will also guide the fresh air flow to flow in a specific direction, reducing the scattering of the fresh air flow and improving the air intake efficiency of the air intake module 100.

[0147] Along the flow direction of the fresh air flow, the air intake cross-sectional area of the air guiding region formed in front of the two wind guiding surfaces 141 on both sides of the same fan 131 is larger than the air intake cross-sectional area of the air guiding region formed behind the two wind guiding surfaces 141 on both sides of the fan 131.

[0148] Specifically, along the flow direction of the fresh air current, the deepest position point of the recess 141a at the front end of the air guiding surface 141 is A1, and the perpendicular distance between the deepest position point A1 and the axis of the blower 131 is the first distance L1. The deepest position point of the recess 141a at the rear end of the air guiding surface 141 is A2, and the perpendicular distance between the deepest position point A2 and the axis of the blower 131 is the second distance L2. Among them, along the inner wall of the recess 141a, the connecting line between the deepest position point A1 and the deepest position point A2 is an arc line, and the first distance L1 is greater than the second distance L2.

[0149] This design of the difference in the air inlet and outlet cross-sectional areas helps to improve the air guiding efficiency of the air guiding module 100. That is, by increasing the air inlet cross-sectional area, it is ensured that sufficient fresh air current can enter the air guiding area, and then by reducing the air outlet cross-sectional area, the flow rate of the fresh air current is increased. That is to say, when the air inlet cross-sectional area is large, more fresh air current can be allowed to enter the air guiding area. Along with the guidance of the air guiding surface 141, the fresh air current is gradually compressed, and the air outlet cross-sectional area becomes smaller, so that the fresh air current can be effectively accelerated.

[0150] As Figures 1 to 7 shown, in some embodiments, the air guiding box 110 includes a first air guiding section and a second air guiding section. The first air guiding section and the second air guiding section are communicated with each other, but the fresh air flow directions inside the two are different.

[0151] The air inlet 11a is arranged at the air inlet end, i.e., the front end, of the first air guiding section. The rear end of the first air guiding section is communicated with the front end of the second air guiding section. The air outlet b11 is arranged at the air outlet end, i.e., the rear end, of the second air guiding section. Among them, the air guiding member 130 is arranged at one end of the first air guiding section close to the second air guiding section.

[0152] The fresh air flow direction in the first air guiding section intersects with the fresh air flow direction in the second air guiding section. That is to say, a bent portion with a predetermined angle is formed at the connection position between the first air guiding section and the second air guiding section. That is, the front end of the second air guiding section can be bent towards the side wall end of the fabric treatment cylinder 11, so that the rear end of the second air guiding section is bent and extended along the side wall of the fabric treatment cylinder, so that the rear end of the second air guiding section can be communicated with the inside of the fabric treatment cylinder 11 through other structures such as a connecting pipe, etc., and further the air guiding box 110 can better adapt to the installation space inside the fabric treatment cylinder. Based on this, an included angle is formed between the first air guiding section and the second air guiding section, and this included angle is the included angle of the bent portion. Among them, the angle range of the included angle is 100° to 150°. In a specific example, the included angle between the first air guiding section and the second air guiding section is 120°.

[0153] In one example, the longitudinal cross-sectional shapes of the first air guiding section and the second air guiding section include oblong rectangles, where the longitudinal cross-section is used to represent a cross-section parallel to the thickness direction of the first air guiding section or the second air guiding section.

[0154] It should be noted that when the longitudinal cross-sectional shapes of the first air guiding section and the second air guiding section are oblong rectangles, a plurality of air guiding members 130 and a plurality of air deflecting members 140 can be uniformly arranged along the length direction of the rectangle. Thus, through the cooperation of the air guiding members 130 and the air deflecting members 140, fresh air can be uniformly delivered into the second air guiding section, and further, the fresh air can be uniformly delivered into the fabric treatment cylinder 11 to improve the uniformity of the effect of fresh air on fabric treatment.

[0155] In addition, in one example, the tail end of the air deflecting member 140 (i.e., the end far from the air inlet 11a) can also extend into the second air guiding section along with the included angle between the first air guiding section and the second air guiding section to improve the air guiding effect of the air deflecting member 140. Wherein, the length of the tail end of the air deflecting member 140 extending into the second air guiding section is not specifically limited.

[0156] As Figures 8 to 9 and referring to the Figures 1 to 7 accompanying drawings, an exemplary embodiment of the present invention provides a fabric treatment device 10, which includes a fabric treatment cylinder 11 and the air guiding module 100 of any of the above embodiments.

[0157] Among them, the air outlet 11b in the air guiding module 100 is connected to the door seal 12 so that the air outlet 11b is communicated with the inside of the fabric treatment cylinder 11 through the door seal 12.

[0158] A breathable tube 13 is provided on the fabric treatment cylinder 11. The air inlet 11a, the fresh air duct 111, the air outlet 11b, the fabric treatment cylinder 11 and the breathable tube 13 in the air guiding module 100 constitute a fresh air circulation channel for fresh air flow.

[0159] In this example, an air outlet structure may not be provided, and the air outlet is directly realized by the breathable tube 13. The breathable tube 13 can be directly communicated with a water box connected to the outer cylinder of the fabric treatment cylinder 11, so that there is no need to additionally provide an exhaust structure. Such a design not only simplifies the overall structure of the machine, reduces the number of components, but also can further reduce the production cost, improve the reliability of the product, the convenience of maintenance and the overall system stability of the fabric treatment device 10.

[0160] Moreover, through the above structural design, that is, directly connecting the door seal 12 with the air outlet 11b, fabric treatment devices 10 such as washing machines and washer-dryers can share a door seal structure, that is, solving the problem of non-universal door seals of existing fabric treatment devices 10.

[0161] In one example, a drying channel (not shown in the figure) may also be provided in the fabric treatment device 10 so that the fabric treatment device 10 has a drying effect. Among them, the second air induction section of the air induction box 110 may also be directly connected to the drying channel so that the fresh air introduced from the air induction module 100 cooperates with the drying air flow in the drying channel, thereby effectively improving the drying efficiency and drying effect of the fabric care device 10.

[0162] In addition, the fabric treatment device 10 may further include a housing 14, and an accommodation space is provided inside the housing 14. Among them, the fabric treatment cylinder 11 is accommodated in the accommodation space, and there is a certain gap between the fabric treatment cylinder 11 and the inner wall of the housing 14. This gap can be used to place the air induction module 100 of any of the above embodiments. Therefore, when the air inlet 11a of the air induction box 110 in the air induction module 100 is in the open state, it can be directly connected to the gap, and the air outlet 11b of the air induction box 110 can be connected to the outer cylinder in the fabric treatment cylinder 11 through the door seal 12. Based on this, when fresh air needs to be introduced into the fabric treatment cylinder 11, there is no need to open holes on the housing 14 of the fabric treatment device 10, thus maintaining the aesthetics of the whole machine and enhancing the appearance design sense of the product. Based on using a large number of existing structural components of the fabric treatment device 10, the structure is further simplified, the use of additional components is reduced, the production cost is lowered, and the overall performance of the product is improved.

[0163] Among them, after the fabric treatment device 10 starts the fresh air program, the drive motor 133 drives a plurality of (such as four) fans 131 to rotate through the drive belt 132, and sucks the outside fresh air into the fresh air duct 111 through the air inlet 11a. A damper assembly 120 is installed on the air inlet 11a. Under the action of the air flow, the damper 121 rotates and the elastic member 122 is compressed, and the air inlet 11a is opened. When the fan 131 stops rotating, the elastic potential energy of the elastic member 122 causes the damper 121 to rotate in the reverse direction and close the air inlet 11a, preventing the risk of overflowing foam at the air inlet 11a during the cleaning and washing stages in the fresh air duct 111 and the fabric treatment cylinder 11. After the fresh air enters the fresh air duct 111, it enters the fabric treatment cylinder 11 in the fresh air duct after being guided by the air guiding member 140. While drying components such as the door seal 12, it blows the wet load (such as fabric) inside the fabric treatment cylinder 11 to avoid the generation of peculiar smell due to the long-term accumulation of the wet load.

[0164] The air guiding member 140 can not only improve the uniformity of air intake, but also support the fresh air duct 111, enhancing the overall strength.

[0165] As Figures 10 to 11 shown, an exemplary embodiment of the present invention provides a fresh air control method, which is used to control the fabric treatment device 10 of any of the above embodiments.

[0166] The fresh air control method includes the following processes: controlling the air extraction component in the air extraction module of the fabric treatment device based on the fresh air program and / or the environmental parameters inside the fabric treatment cylinder and / or the environmental parameters outside the fabric treatment cylinder and / or the operating parameters of the fabric treatment cylinder, wherein the air damper in the air extraction module is linked with the air extraction component.

[0167] Specifically, the process of controlling the air extraction component in the air extraction module of the fabric treatment device based on the fresh air program, wherein the process that the air damper in the air extraction module is linked with the air extraction component includes the following steps:

[0168] Step S100: After the fabric treatment device finishes running the washing program, when the door of the fabric treatment cylinder in the fabric treatment device is not opened within a predetermined time, determine whether the external environment meets the introduction requirements for running the fresh air program.

[0169] Step S200: If it meets the requirements, run the fresh air program, and the fresh air program is used to control the running rhythm of the fan in the air extraction module and the rotation rhythm of the fabric treatment cylinder, and the running rhythm of the fan includes intermittent operation.

[0170] In this step S200, during the running of the fresh air program, control the fan in the air extraction module 100 to run, and the intermittent operation of the fan is: after the fan runs for a first time, control the fan to stop running for a second time, and during the running of the fan, control the fabric treatment cylinder to rotate forward and backward at a low speed.

[0171] Step S300: If the running time of the fresh air program reaches the first preset time and the door is not opened, stop running the fresh air program.

[0172] Step S400: If the fresh air program stops running for the second preset time and the door is still not opened, then run the fresh air program when the external environment meets the introduction requirements for running the fresh air program.

[0173] Step S500: If the door is opened, stop running the fresh air program.

[0174] Wherein, in any of the above steps, at any stage of the running of the fresh air program, taking the opening of the door as the judgment end point for the end of the running of the fresh air program. In addition, the first preset time can be the same as the second preset time, or the first preset time can also be different from the second preset time.

[0175] Specifically, after the washing program of the fabric treatment device 10 ends, during the running of the fresh air program, if the user still does not open the door of the fabric treatment cylinder 11 after a predetermined time, such as 30 minutes, the fabric treatment device 10 will automatically detect whether the external temperature and humidity meet the introduction requirements for running the fresh air program.

[0176] If the temperature and humidity of the air in the external environment are appropriate, for example, the relative humidity of the external environment ≤ 70%, the fabric treatment device 10 will start the fresh air program. The fan 131 will start and continuously run for the first period of time such as 3 minutes. During this period, the fan 131 will introduce external fresh air to help discharge the moisture and odor inside the fabric treatment cylinder 11. At the same time, it will cooperate with the low-speed rotation of the inner cylinder of the fabric treatment cylinder 11 (such as alternating forward and reverse rotation for 15 s each), and the fan inside the cylinder will run synchronously during the forward and reverse rotation of the inner cylinder. This operation mode helps the air to be evenly distributed on the load inside the washing machine, improves the ventilation effect, and further reduces the dampness and odor of the clothes. Among them, in this stage, if the door body is opened, the fresh air program will stop running.

[0177] After the fan 131 runs for 3 minutes, the fabric treatment device 10 will enter a pause stage for the second period of time such as 15 minutes. During this period, the fan 131 stops running, but the fabric treatment device 10 will continue to monitor the temperature and humidity of the air in the external environment and prepare for the introduction of fresh air in the next stage.

[0178] During the entire fresh air program process, the user can open the door body at any time. Once the door body is opened, the fresh air program will immediately terminate.

[0179] When the running time of the fresh air program reaches the first preset time T0, for example, 2 hours, and the user still has not opened the door body, the fabric treatment device 10 will automatically give a warning to remind the user to temporarily exit the fresh air program. Ensure that the system will not run indefinitely without the user's long-term intervention, thereby saving energy and protecting the device. At the end of the fresh air program, the fabric treatment device 10 will close all relevant components and return to the standby state.

[0180] During the pause operation of the fresh air program, if the stop running time of the fan 131 reaches the second preset time T1, such as 2 hours, and the user still has not opened the door body, then when the external environment meets the introduction requirements of the fresh air program, that is, when the external temperature and humidity are appropriate, the fresh air program will be restarted in a cycle, and the operation mode is the same as described above, cycling until the user opens the door body. That is to say, before the user opens the door body, the fresh air program runs for the first preset time T0, pauses for the second preset time T1, runs for the first preset time T0, pauses for the second preset time T1, etc., cycling until the user opens the door body.

[0181] If the user has opened the door body before the end of the laundry program and the fresh air program, the fabric treatment device 10 will also automatically terminate the fresh air program.
