Description

Technical Field

[0002] With the improvement of living standards, the development of the washing machine industry has also shown a diversified trend, and with the improvement of people's living standards, the demand for washing machines has gradually increased. Drum washing and drying machines have also gradually entered people's daily lives to meet people's growing demand for fabric care.

[0003] Most drum washing and drying machines on the market use heat pump drying and condensation drying technology. During the drying stage, the above-mentioned drum washing and drying machines generally heat the air in a closed environment, condense and dry it, and then circulate it until the fabric is dried. However, the drying efficiency of existing drum washing and drying machines is low, resulting in a long drying time for the fabric.

[0004] In addition, when the fabric is dried, if the user forgets to take out the dried fabric in time, the fabric will accumulate in the drum for a long time, which is easy to breed bacteria or mold. In addition, most drum washing and drying machines do not have a separate deodorizing function when drying clothes. The deodorizing of fabrics still depends on the softener and the effect after washing, resulting in a poor user experience of drum washing and drying machines. Summary of the invention

[0064] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0065] like Figure 1 As shown, an exemplary embodiment of the present invention provides a fabric processing device 100. The fabric processing device 100 may include but is not limited to a washing machine, and the washing machine may include but is not limited to a washing and care machine, a washing and drying machine, etc. For example, the washing machine may be a drum washing machine or a pulsator washing machine with a drying function, etc. Of course, the washing machine may also be other types of fully automatic washing machines.

[0066] Alternatively, the fabric processing device 100 may also be a clothes dryer, which may include but is not limited to a direct-discharge clothes dryer, a condensing clothes dryer or a heat pump clothes dryer, etc. In this example and the following examples, the fabric processing device 100 is described as a drum clothes dryer with a drying function.

[0067] The fabric treatment device 100 includes a housing 110, a fabric treatment cylinder 120 and a pressure balance member 130. The housing 110 is configured as a housing space, which can provide a place for installation and operation of the fabric treatment cylinder 120, the air duct 111, the fan 112 and other related components (various functional modules such as a disinfection module, an ozone module, etc.). In addition, the housing space can also accommodate and protect all the components inside it, prevent external factors (such as dust, foreign matter, etc.) from interfering with the internal components of the housing space, and also help reduce the noise generated during the operation of the fabric treatment device 100 from propagating outward.

[0068] An air duct 111 is provided in the accommodating space. The air duct 111 may be a fresh air duct for cooling the fabric processing drum 120 , or may be a drying duct for drying the fabric in the fabric processing drum 120 .

[0069] It should be noted that the structure and shape of the air duct 111 can be flexibly designed according to its arrangement position, and its shape can be curved or straight, or can also have different cross-sectional shapes (such as circular, rectangular, etc.).

[0070] A fan 112 is provided in the air duct 111, and the fan 112 may include but is not limited to a centrifugal fan, an axial flow fan, etc. The fan 112 can allow fresh air to enter the fabric processing drum 120, and exchange air with the inside of the fabric processing drum 120. Alternatively, the fan 112 can also be used to circulate the drying airflow in the fabric processing drum 120, so as to dry the fabric in the fabric processing drum 120.

[0071] The fabric treatment cylinder 120 is rotatably disposed in the accommodating space, so that the fabric can be fully treated (such as dried, cleaned, etc.) in the fabric treatment cylinder 120. The air inlet and outlet ends of the air duct 111 are both connected to the interior of the fabric treatment cylinder 120, thereby forming a gas circulation loop that can dry the fabric or deodorize the fresh air.

[0072] Among them, the air duct 111 can be arranged around the outer wall of the fabric processing cylinder 120, and the air inlet end of the air duct 111 is connected to the interior of the fabric processing cylinder 120. The air inlet end of the air duct 111 can be arranged at the cylinder mouth position of the fabric processing cylinder 120 to realize the front air inlet structure of the fabric processing cylinder 120.

[0073] Alternatively, the air inlet end of the air duct 111 can be arranged at the bottom of the fabric processing drum 120, and multiple air inlet ends can be arranged in a divergent manner to achieve that the drying airflow or fresh air entering the fabric processing drum 120 can be blown directly from the bottom of the drum to the drum mouth, thereby ensuring and improving the drying efficiency or deodorizing effect of the fabric. Among them, the multiple air inlet ends can enter the drum in a clockwise or counterclockwise direction and in an oblique direction.

[0074] Alternatively, the air inlet end of the air duct 111 can also be arranged on the side wall of the fabric treatment cylinder 120, and arranged along the tangential position of the cylinder wall of the fabric treatment cylinder 120, so as to enter the interior of the fabric treatment cylinder 120 along the tangential direction of the cylinder wall, so that the airflow entering the fabric treatment cylinder 120 can rotate in the cylinder, thereby contacting more surfaces of the fabric, improving the drying efficiency of the fabric, or improving the deodorization effect of the fabric. For example, multiple air inlet ends correspond to multiple air duct branches, and multiple air duct branches are arranged on the fabric treatment cylinder 120 along the direction of the spiral line, so that multiple air inlet ends can enter the fabric treatment cylinder 120 along the arc direction of the inner wall of the fabric treatment cylinder 120.

[0075] The air outlet end of the air duct 111 may be disposed on the fabric processing cylinder 120 at a position opposite to the air inlet end of the air duct 111, which is not specifically limited herein.

[0076] When the fan 112 is working, air enters the fabric treatment drum 120 from the air inlet end of the air duct 111, exchanges heat and humidity with the fabric in the drum, and then returns to the air duct 111 from the air outlet end. This air circulation can help improve the efficiency of fabric treatment, for example, in the drying process, it can remove moisture from the fabric more quickly.

[0077] During the fabric treatment process, the connection between the air duct 111 and the fabric treatment drum 120 ensures the stability of the treatment environment. By continuously exchanging gas, the temperature, humidity and air pressure in the drum can be maintained within a suitable range. For example, in the fresh air program, fresh air can continuously enter the fabric treatment drum 120, improving the air quality in the drum and facilitating the fabric treatment effect.

[0078] The pressure balance member 130 is disposed on the air duct 111, one end of the pressure balance member 130 is in communication with the inside of the air duct 111, and the other end of the pressure balance member 130 is in communication with the accommodating space. Based on this, when there is a pressure difference between the fabric treatment drum 120 and the air duct 111, the pressure balance member 130 can perform a corresponding pressure balancing action in the air duct 111, so that the pressure in the fabric treatment drum 120 is maintained within a reasonable range, thereby ensuring the drying efficiency or deodorization effect of the fabric. For the specific improvement of the drying efficiency and the improvement of the deodorization effect, please refer to the description of the following embodiments.

[0079] The pressure balance member 130 has a plurality of preset pressure thresholds, which can be set according to the optimal air pressure state of the fabric treatment drum under different operating programs (such as a drying program, a fresh air program, etc.).

[0080] Among them, the multiple preset pressure thresholds may include a high temperature threshold P 高 , Normal temperature threshold P 常 and low temperature threshold P 低High temperature threshold P 高 The value is greater than the normal temperature threshold P 常 The value of the normal temperature threshold P 常 The value is greater than the low temperature threshold P 低 The value of the normal temperature threshold P 常 It is the atmospheric pressure value or the ambient pressure of the environment in which the fabric processing device 100 is located.

[0081] That is, when the fabric processing device 100 runs different programs, the corresponding preset pressure threshold of the pressure balance member 130 can be enabled. When the fabric processing device 100 runs the drying program or the fresh air program, the pressure balance member 130 dynamically balances the air pressure in the fabric processing cylinder 120 based on different preset pressure thresholds. When the air pressure in the fabric processing cylinder 120 is too high, the pressure balance member 130 will enable the corresponding preset pressure threshold, thereby opening the corresponding channel, so that the gas flows from the air duct 111 to the accommodating space or vice versa, so as to reduce or increase the air pressure in the fabric processing cylinder 120, maintain the balance and stability of the air pressure in the fabric processing cylinder 120, and in the drying program, the appropriate air pressure can ensure that the moisture evaporates evenly from the fabric, avoiding the situation of local over-dryness or moisture, thereby improving the drying efficiency or deodorization effect of the fabric.

[0082] For example, when the fabric processing device 100 runs a drying program, the drying process of the fabric includes heating, dehumidification and drying stages. The pressure in the fabric processing drum 120 will change in each stage. At this time, the high temperature threshold P of the pressure balance member 130 can be activated. 高 and normal temperature threshold P 常 .

[0083] For example, in the drying state, when the temperature of the fabric treatment drum 120 reaches a certain value, the high temperature threshold value P 高 At this time, if the air pressure in the fabric treatment drum 120 reaches the high temperature threshold value P 高 The pressure balance member 130 will automatically open and realize conduction from the fabric treatment cylinder 120 to the accommodating space, discharging a portion of the humid and hot air in the fabric treatment cylinder 120 into the accommodating space, thereby taking out some water vapor. This process helps to accelerate the drying speed of the fabric in the fabric treatment cylinder 120.

[0084] As the drying process proceeds, the temperature in the fabric treatment drum 120 gradually decreases, and the air pressure also decreases accordingly. 常When the pressure balance member 130 is in the state of being connected, that is, the connection from the accommodating space to the fabric treatment cylinder 120, fresh air from the outside will be sucked into the fabric treatment cylinder 120 under the action of the fan 112. This not only helps to balance the air pressure difference inside and outside the fabric treatment cylinder 120, but also brings fresh air from the outside into the fabric treatment cylinder 120, thereby accelerating the cooling rate and effectively improving the drying effect on the fabric.

[0085] For another example, when the fabric processing device 100 runs the fresh air program, that is, in the non-drying state, the air pressure in the fabric processing drum 120 is controlled by adjusting the speed of the fan 112. When the speed of the fan 112 is high, for example, higher than a preset value, the air flow rate in the air duct 111 increases, causing the air pressure in the fabric processing drum 120 to decrease until the low temperature threshold value P is reached. 低 At this time, the pressure balance member 130 will open and realize the conduction from the accommodating space to the fabric treatment cylinder 120. At this time, the fresh air from the outside will be sucked into the fabric treatment cylinder 120 under the action of the fan 112 to replenish the air volume in the fabric treatment cylinder 120. This not only helps to maintain the air circulation in the fabric treatment cylinder 120, but also prevents the air in the fabric treatment cylinder 120 from becoming dirty.

[0086] When the speed of the fan 112 decreases or stops, that is, it is lower than the preset value, the air pressure in the fabric processing drum 120 will gradually increase until it reaches the normal temperature threshold value P 常 At this time, the pressure balance member 130 will open again and realize the conduction from the fabric treatment drum 120 to the accommodating space, and discharge part of the air in the fabric treatment drum 120 to maintain the air pressure balance inside and outside the fabric treatment drum 120. In this way, the air inside and outside the fabric treatment drum 120 can be circulated, ensuring that the fabric treatment drum 120 always maintains a fresh air environment, thereby preventing the reproduction of bacteria in the fabric treatment drum 120 and reducing the mildew of the fabrics. It can also realize the deodorization function of the fresh air program in the drying mode, and reduce the bacteria generated in the fabric treatment drum 120 after the fabrics are placed in the fabric treatment drum 120 for a long time after washing and drying, thereby improving the deodorization effect of the fabrics.

[0087] There are at least a first passage and a second passage in the pressure balance member 130. When the pressure in the fabric treatment drum 120 is higher than the pressure in the accommodating space (i.e., the outside), the first passage is connected so that the fabric treatment drum 120 is connected to the accommodating space. At this time, part of the hot and humid air or air in the fabric treatment drum 120 can be directly discharged into the accommodating space to reduce the pressure in the fabric treatment drum 120.

[0088] Furthermore, when the pressure of the accommodating space is higher than the pressure inside the fabric treatment cylinder 120, the second passage is opened so that the accommodating space is connected to the fabric treatment cylinder 120. At this time, under the action of the fan 112, fresh air from the outside can be introduced into the fabric treatment cylinder 120, and the fabric treatment cylinder 120 can be cooled and / or deodorized.

[0089] like Figure 1 As shown, in some embodiments, the pressure balance member 130 is arranged near the fan 112. The pressure balance member 130 is arranged near the fan 112 to meet the compactness of the internal space layout of the fabric processing device 100. The pressure balance member 130 is arranged near the fan 112, which can effectively utilize the limited space. This layout can also reduce the design length of the air duct 111, thereby reducing the resistance of the gas flowing in the air duct 111, which helps to improve the efficiency of the entire gas circulation system.

[0090] At the same time, the pressure balance member 130 is arranged near the fan 112, which makes it more convenient for technicians to install or repair. When assembling the equipment, the air duct 111 between the two can be connected more conveniently, reducing the complexity of installation. At the same time, if a problem occurs during the operation of the equipment, the maintenance personnel can locate the pressure balance member 130 and the related parts of the fan 112 more quickly, reducing the maintenance time.

[0091] The fan 112 is the power source for the air flow in the air duct 111, and the air flow velocity, pressure and other parameters generated by the fan 112 have a key impact on the operation of the entire fabric processing device 100. The pressure balance member 130 is arranged near the fan 112, and can more timely and accurately sense the changes in the air pressure in the air duct 111 caused by the operation of the fan 112. For example, when the fan 112 is started or the speed is changed, the air pressure in the air duct 111 will change rapidly, and the pressure balance member 130 near the fan 112 can quickly respond to this change.

[0092] In the drying process, the fan 112 will adjust the rotation speed according to the set drying speed. The pressure balancing component 130 close to the fan 112 can dynamically balance the air pressure in the fabric processing drum 120 according to the preset pressure threshold in real time according to the air pressure fluctuation caused by the change in the rotation speed of the fan 112, thereby ensuring that the fabric is dried in a suitable air pressure environment, so as to ensure and improve the drying efficiency of the fabric.

[0093] In addition, when the speed of the fan 112 is unstable due to power supply voltage fluctuation, the air pressure in the air duct 111 will be unstable. At this time, the adjacent pressure balance member 130 can quickly balance the unstable air pressure, ensuring that the air pressure in the fabric treatment drum 120 is always maintained within a range that is beneficial to fabric treatment, thereby ensuring the stability of the fabric treatment process and preventing the fabric from being partially under-dried or over-dried due to unstable air pressure in the fabric treatment drum 120 during the drying process.

[0094] like Figure 1 As shown, in some embodiments, the pressure balance member 130 includes a first conductive state and a second conductive state.

[0095] When the pressure balance member 130 is in the first conducting state, fresh air in the accommodating space can enter the fabric processing cylinder 120 through the pressure balance member 130 .

[0096] The fresh air delivered to the fabric treatment drum 120 has different temperature and humidity characteristics. In some cases, the introduction of relatively dry fresh air helps to accelerate the drying of the fabric. Moreover, the entry of fresh air can promote the air flow in the fabric treatment drum 120, making the heat and humidity distribution more uniform. For example, when processing a large amount of fabric, there may be local uneven temperature and humidity in the drum, and the inflow of fresh air can break this unevenness and ensure that all parts of the fabric can be effectively treated.

[0097] When the pressure balance member 130 is in the second conducting state, the air in the fabric processing cylinder 120 can be discharged into the accommodating space through the pressure balance member 130 .

[0098] In the drying process, the synergistic effect of the first conduction state and the second conduction state is crucial. At the beginning, the first conduction state can be used more often to allow fresh air to enter the fabric treatment drum 120. The fresh air brings relatively dry air and heat, which helps to improve the drying efficiency. As the drying process proceeds, the moisture in the fabric continues to evaporate, and the air humidity in the fabric treatment drum 120 increases. At this time, the second conduction state begins to play an important role, discharging the air with higher humidity into the accommodating space. At the same time, it can be switched back to the first conduction state in time to introduce fresh air, maintain the dryness of the air in the fabric treatment drum 120 and the continuous supply of heat, thereby achieving an efficient drying process.

[0099] The reasonable switching of the two conduction states directly affects the quality of fabric processing. If the fresh air is not introduced enough in the first conduction state or the exhaust is not smooth in the second conduction state, the environment in the fabric processing cylinder 120 may be unfavorable for fabric processing. For example, the fabric may not be dried thoroughly, have residual odor, or have wrinkles. Only when the two conduction states are switched according to appropriate logic and frequency can the fabric be guaranteed to be in the best environment during the processing, thereby improving the quality of fabric processing.

[0100] like Figure 1 As shown, in some embodiments, the plurality of preset pressure thresholds may include a high temperature threshold P 高 , Normal temperature threshold P 常 and low temperature threshold P 低 High temperature threshold P 高 The value is greater than the normal temperature threshold P 常 The value of the normal temperature threshold P 常 The value is greater than the low temperature threshold P 低 The value of the normal temperature threshold P 常 It is the atmospheric pressure value or the ambient pressure of the environment in which the fabric processing device 100 is located.

[0101] When the fabric processing device 100 runs a drying program, the high temperature threshold value P among the plurality of preset pressure threshold values ​​is enabled. 高 , Normal temperature threshold P 常 .

[0102] In the drying state, when the temperature of the fabric treatment drum 120 reaches a certain value, the high temperature threshold value P 高 At this time, if the first pressure value in the fabric treatment drum 120 reaches the high temperature threshold value P 高 The pressure balance member 130 is in the second conduction state to achieve conduction from the fabric treatment cylinder 120 to the accommodating space, and discharge a portion of the humid and hot air in the fabric treatment cylinder 120 into the accommodating space, thereby taking out part of the water vapor. This process helps to accelerate the drying speed of the fabric in the fabric treatment cylinder 120.

[0103] As the drying process proceeds, the temperature in the fabric treatment drum 120 gradually decreases, and the air pressure also decreases accordingly. When the first air pressure value P1 in the fabric treatment drum 120 drops to the normal temperature threshold value P 常 When the pressure balance member 130 is below, it will switch to the first conduction state, that is, the conduction from the accommodating space to the fabric treatment cylinder 120. At this time, fresh air from the outside will be sucked into the fabric treatment cylinder 120 under the action of the fan 112. This not only helps to balance the air pressure difference inside and outside the fabric treatment cylinder 120, but also can bring fresh air from the outside into the fabric treatment cylinder 120, accelerate the cooling rate, and effectively improve the drying effect on the fabric.

[0104] When the temperature in the fabric treatment drum 120 is lower than the set temperature, and the pressure in the fabric treatment drum 120 is equal to the normal temperature threshold value P 常 When the temperature is equal, the drying process is ended, wherein the set temperature is the temperature at which the fabric treatment drum 120 is allowed to be opened.

[0105] When the fabric treatment device 100 runs the fresh air program, the low temperature threshold value P among the plurality of preset pressure threshold values ​​is enabled. 低 , Normal temperature threshold P 常 .

[0106] When the fabric processing device 100 runs the fresh air program, that is, in the non-drying state, the air pressure in the fabric processing drum 120 is controlled by adjusting the speed of the fan 112. When the speed of the fan 112 is high, such as higher than a preset value, the air flow rate in the air duct 111 increases, causing the second air pressure value P2 in the fabric processing drum 120 to decrease until it reaches the low temperature threshold value P 低 At this time, the pressure balance member 130 is in the first conducting state to achieve conduction from the accommodating space to the fabric treatment drum 120. At this time, fresh air from the outside is sucked into the fabric treatment drum 120 under the action of the fan 112 to replenish the air volume in the fabric treatment drum 120. This not only helps to maintain the air circulation in the fabric treatment drum 120, but also prevents the air in the fabric treatment drum 120 from becoming dirty.

[0107] It should be noted that the preset value of the rotation speed of the fan 112 may be any value between 60% and 80% of the maximum rotation speed value allowed by the fan 112 .

[0108] When the speed of the fan 112 decreases or stops, that is, it is lower than the preset value, the air pressure in the fabric processing drum 120 will gradually increase until it reaches the normal temperature threshold value P 常 At this time, the pressure balance member 130 is in the second conduction state, and conduction from the fabric treatment drum 120 to the accommodating space is achieved, and part of the air in the fabric treatment drum 120 is discharged to maintain the air pressure balance inside and outside the fabric treatment drum 120. In this way, the air inside and outside the fabric treatment drum 120 can be circulated, ensuring that the fabric treatment drum 120 always maintains a fresh air environment, thereby preventing bacteria from breeding in the fabric treatment drum 120 and reducing the mildew of the fabrics. It can also realize the deodorization function of the fresh air program in the drying mode, and reduce the bacteria generated in the fabric treatment drum 120 after the fabrics are washed and dried for a long time, thereby improving the deodorization effect of the fabrics.

[0109] When the number of cycles of the pressure balance member 130 switching between the first conduction state and the second conduction state reaches a set number and the pressure in the fabric treatment drum is equal to the normal temperature threshold, the fresh air program is ended.

[0110] Alternatively, after the operation time of the pressure balance member 130 switching back and forth between the first on state and the second on state ends, and the pressure in the fabric treatment drum is equal to the normal temperature threshold, the fresh air program ends.

[0111] like Figure 1 As shown, in some embodiments, the pressure balance member 130 may include, but is not limited to, an electronic two-way air pressure valve.

[0112] An electronic two-way air pressure valve is a device that can control the direction and pressure of gas flow. It usually consists of a valve body, a valve core and a control circuit. There are two ports on the valve body, one for gas inlet and one for gas outflow. The valve core can move in the valve body to change the flow path of the gas. The control circuit controls the position of the valve core according to the preset pressure threshold, thereby adjusting the gas pressure.

[0113] In the fabric processing device 100, the main function of the electronic two-way air pressure valve is to dynamically balance the air pressure in the fabric processing drum 120 based on different preset pressure thresholds when the fabric processing device 100 runs a drying program or a fresh air program.

[0114] Specifically, when the air pressure in the fabric processing cylinder 120 deviates from the normal pressure range, the electronic two-way air pressure valve will adjust the position of the valve core according to the instructions of the control circuit, so that the gas flows from the air duct 111 to the accommodating space or vice versa, so as to lower or increase the air pressure in the cylinder, thereby maintaining the stability of the air pressure in the fabric processing cylinder 120.

[0115] That is to say, there are at least a first passage and a second passage in the electronic two-way air pressure valve. When the pressure in the fabric treatment cylinder 120 is higher than the pressure in the accommodation space (i.e., the outside), the first passage is opened to connect the fabric treatment cylinder 120 to the accommodation space, and part of the hot and humid air or air in the fabric treatment cylinder 120 is directly discharged into the accommodation space to reduce the pressure in the fabric treatment cylinder 120.

[0116] Furthermore, when the pressure of the accommodating space is higher than the pressure inside the fabric treatment cylinder 120, the second passage is opened to allow conduction from the accommodating space to the fabric treatment cylinder 120. Under the action of the fan 112, fresh air from the outside is introduced into the fabric treatment cylinder 120, and the fabric treatment cylinder 120 is cooled and / or deodorized.

[0117] like Figure 2 and Figure 3 As shown, an exemplary embodiment of the present invention provides a control method for a fabric processing device, which is applied to the fabric processing device as in any of the above embodiments, and the control method comprises the following steps:

[0118] Step S100: determining the operating program type of the fabric processing device.

[0119] Step S200: Based on the type of the operating program, the pressure in the fabric treatment drum is dynamically balanced by controlling the conduction state of the pressure balance member in the air duct.

[0120] In step S100, the user can select the corresponding operating program type according to the processing requirements of the fabric, for example, when drying the fabric, choose to run the drying program; when deodorizing the fabric, choose to run the fresh air program.

[0121] In one example, when the fabric processing device 100 is not powered off, after the fabric drying is completed, if the user forgets to take out the dried fabric in time, in order to prevent the fabric from being left in the fabric processing drum 120 for a long time and becoming moldy or breeding bacteria, the control system of the fabric processing device 100 can autonomously start and run the fresh air program according to the placement time of the fabric in the fabric processing drum 120, and the fresh air program can be repeated multiple times.

[0122] In step S200, the pressure balance member 130 includes a first conduction state and a second conduction state. When the pressure in the fabric treatment drum 120 is greater than or equal to the first threshold, the pressure balance member 130 is controlled to be in the second conduction state, and when the pressure in the fabric treatment drum 120 is less than or equal to the second threshold, the pressure balance member 130 is controlled to be in the first conduction state, and the first threshold is greater than the second threshold.

[0123] Specifically, when the pressure balance member 130 is in the first conduction state, fresh air in the accommodating space can enter the fabric treatment drum 120 through the pressure balance member 130. Also, when the pressure balance member 130 is in the second conduction state, air in the fabric treatment drum 120 can be discharged into the accommodating space through the pressure balance member 130.

[0124] When the fabric processing device 100 runs a drying program, the high temperature threshold value P among the plurality of preset pressure threshold values ​​is enabled. 高 , Normal temperature threshold P 常 Among them, the high temperature threshold P 高 That is, the first threshold, the normal temperature threshold P 常 That is the second threshold.

[0125] In the drying state, when the temperature of the fabric treatment drum 120 reaches a certain value, the high temperature threshold value P 高 At this time, if the first pressure value in the fabric treatment drum 120 reaches the high temperature threshold value P 高, control the pressure balance member 130 to be in the second conduction state to achieve conduction in the direction from the fabric treatment cylinder 120 to the accommodating space, discharge a part of the humid and hot air in the fabric treatment cylinder 120 into the accommodating space, thereby taking out part of the water vapor. This process helps to accelerate the drying speed of the fabric in the fabric treatment cylinder 120.

[0126] When the pressure balance member 130 is in the second on state, the air pressure in the fabric treating cylinder 120 can be dynamically balanced.

[0127] As the drying process proceeds, the temperature in the fabric treatment drum 120 gradually decreases, and the air pressure also decreases accordingly. When the first air pressure value P1 in the fabric treatment drum 120 drops to the normal temperature threshold value P 常 When the pressure balance member 130 is controlled to be switched to the first conduction state, that is, the conduction from the accommodating space to the fabric treatment cylinder 120. At this time, fresh air from the outside will be sucked into the fabric treatment cylinder 120 under the action of the fan 112. This not only helps to balance the air pressure difference inside and outside the fabric treatment cylinder 120, but also brings fresh air from the outside into the fabric treatment cylinder 120, thereby accelerating the cooling rate and effectively improving the drying effect on the fabric.

[0128] When the temperature in the fabric treatment drum 120 is lower than the set temperature, and the pressure in the fabric treatment drum 120 is equal to the normal temperature threshold value P 常 When the temperature is equal, the drying process is ended, wherein the set temperature is the temperature at which the fabric treatment drum 120 is allowed to be opened.

[0129] When the fabric treatment device 100 runs the fresh air program, the low temperature threshold value P among the plurality of preset pressure threshold values ​​is enabled. 低 , Normal temperature threshold P 常 Among them, the normal temperature threshold P 常 That is, the first threshold, the low temperature threshold P 低 That is the second threshold.

[0130] When the fabric treatment device 100 runs the fresh air program, that is, in the non-drying state, the air pressure in the fabric treatment drum 120 is controlled by adjusting the speed of the fan 112. When the speed of the fan 112 is high, the air flow rate in the air duct 111 increases, causing the second air pressure value P2 in the fabric treatment drum 120 to decrease until it reaches the low temperature threshold value P 低 At this time, the pressure balance member 130 is controlled to be in the first conducting state to achieve conduction from the accommodating space to the fabric treatment drum 120. At this time, fresh air from the outside is sucked into the fabric treatment drum 120 under the action of the fan 112 to replenish the air volume in the fabric treatment drum 120. This not only helps to maintain the air circulation in the fabric treatment drum 120, but also prevents the air in the fabric treatment drum 120 from becoming dirty.

[0131] When the speed of the fan 112 decreases or stops, the air pressure in the fabric processing drum 120 gradually increases until it reaches the normal temperature threshold value P 常 At this time, the pressure balance member 130 is controlled to be in the second conduction state, and conduction is achieved in the direction from the fabric treatment drum 120 to the accommodating space, so that part of the air in the fabric treatment drum 120 is discharged to maintain the air pressure balance inside and outside the fabric treatment drum 120. In this way, the air inside and outside the fabric treatment drum 120 can be circulated, ensuring that the fabric treatment drum 120 always maintains a fresh air environment, thereby preventing bacteria from breeding in the fabric treatment drum 120 and reducing the mildew of the fabrics. It can also realize the deodorization function of the fresh air program in the drying mode, and reduce the bacteria generated in the fabric treatment drum 120 after the fabrics are placed in the fabric treatment drum 120 for a long time after washing and drying, thereby improving the deodorization effect of the fabrics.

[0132] When the number of cycles of the pressure balance member 130 switching between the first conduction state and the second conduction state reaches a set number and the pressure in the fabric treatment drum is equal to the normal temperature threshold, the fresh air program is ended.

[0133] Alternatively, after the operation time of the pressure balance member 130 switching back and forth between the first on state and the second on state ends, and the pressure in the fabric treatment drum is equal to the normal temperature threshold, the fresh air program ends.
