Description

Technical Field

[0001] The present application relates to the field of clothing processing, and in particular, to a drying method, a control method and clothing processing equipment. Background Art

[0002] The functions of clothing treatment equipment have been increasing with the development of science and technology, from washing in the beginning to the current washing, drying and care and other processing functions, which have improved the user experience of clothing treatment equipment. When the current clothing treatment equipment is drying clothes, condensed water will be introduced. The humidity of the drying airflow increases after contacting with the clothes, and then decreases after contacting with the condensed water, thus achieving dehumidification of the drying airflow.

[0003] However, since the condition of the clothes that need to be dried each time is different, the evaporation rate of water in the clothes is also different, so when the current clothing processing equipment dries the clothes, it is easy for the evaporation rate to be lower than the condensation rate of the condensed water on the drying airflow, resulting in a decrease in drying efficiency. Summary of the invention

[0004] The embodiments of the present application provide a drying method, a control method and a clothing processing device to at least solve the technical problem of reduced drying efficiency.

[0005] According to a first aspect of an embodiment of the present application, a drying method is provided, which is applied to a clothes processing device with a drying function, wherein the clothes processing device comprises a processing drum and a drying air duct, wherein a heater and a double-suction fan are arranged in the drying air duct, and a drying air flow circulates between the processing drum and the drying air duct under the agitation of the double-suction fan, wherein the double-suction fan is further used to introduce fresh air into the drying air duct, and wherein the heater is used to heat the drying air flow, and the method comprises:

[0006] In the condensation stage, the double suction fan is controlled to start, the heater is kept in an on state, and the condensation function of the clothes processing device is started, wherein the condensation function can condense the drying airflow after being started;

[0007] After the condensation function is started, the on / off condition of the condensation function is adjusted according to the periodically acquired airflow temperature to balance the condensation rate and the evaporation rate, wherein the on / off condition includes the start time and / or the shut down time of the condensation function;

[0008] The step of adjusting the on / off state of the condensation function according to the periodically acquired airflow temperature includes:

[0009] As the air flow temperature increases, the start-up time is increased and / or the shut-down time is decreased.

[0010] According to this embodiment, the air flow temperature of the drying air flow in the processing cylinder is monitored and the opening and closing of the condensation function is adjusted so that the condensation rate and the evaporation rate are balanced, thereby improving the drying efficiency.

[0011] In combination with the first aspect, in an optional implementation of the embodiment of the present application, increasing the startup time and / or decreasing the shutdown time as the airflow temperature increases includes:

[0012] The proportion of the startup time increases as the temperature range of the airflow temperature increases, and / or the proportion of the shutdown time decreases as the airflow temperature increases, wherein the proportion of the startup time refers to the ratio of the startup time to the sum of the startup time and the shutdown time, and the proportion of the shutdown time refers to the ratio of the shutdown time to the sum of the startup time and the shutdown time.

[0013] With this implementation, when the airflow temperature increases, the evaporation rate increases. At this time, increasing the startup time helps to increase the condensation rate, thereby balancing the condensation rate and the evaporation rate and improving the drying efficiency. Similarly, the shutdown time can be reduced to balance the condensation rate and the evaporation rate and improve the drying efficiency.

[0014] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0015] If the airflow temperature obtained periodically exceeds a preset second temperature threshold, the start time is increased and the shutdown time is decreased, wherein, among the airflow temperatures obtained periodically, each time the airflow temperature exceeds the second temperature threshold, the start time is increased once and the shutdown time is decreased once;

[0016] If the periodically acquired airflow temperature is between the second temperature threshold and the first temperature threshold, the startup time is increased, wherein the startup time is increased once each time the airflow temperature is between the second temperature threshold and the first temperature threshold in the periodically acquired airflow temperature;

[0017] If the periodically acquired airflow temperature is lower than the first temperature threshold, the startup time is reduced, wherein the startup time is reduced once each time the airflow temperature is lower than the first temperature threshold among the periodically acquired airflow temperatures;

[0018] The first temperature threshold is lower than the second temperature threshold.

[0019] By adopting this implementation method, the air flow temperature is monitored by setting the first temperature threshold and the second temperature threshold. As the number of air flow temperature detections increases, the number of adjustments to the on and off conditions of the condensation function will also increase accordingly, which is beneficial to improving the balance efficiency between the condensation rate and the evaporation rate, thereby improving the drying efficiency.

[0020] In combination with the first aspect, in an optional implementation of the embodiment of the present application, after the condensation function is started, the method further includes:

[0021] If the proportion of the startup time exceeds a preset ratio threshold or the shutdown time is zero, the heating power of the heater is reduced when the startup time needs to be increased, and the heating power of the heater is increased when the shutdown time needs to be reduced.

[0022] By adopting this implementation, in addition to adjusting the start and stop time of the condensation function, the heating power of the heater can also be adjusted, which helps to improve the balance efficiency between the condensation rate and the evaporation rate, thereby improving the drying efficiency.

[0023] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the drying air duct is provided with an exhaust port that can be controlled to be opened and closed, and the method further includes:

[0024] If the air flow temperature exceeds a preset first temperature threshold, the exhaust port is controlled to open.

[0025] With this implementation, the air outlet helps to balance the air pressure in the drying air duct.

[0026] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0027] During the temperature rising stage of the drying airflow, the fresh air inlet and the air outlet of the double-suction fan are controlled to be closed.

[0028] With this implementation, after the fresh air inlet and outlet are closed, air from the external environment is not easy to enter the drying duct, so that the heater can quickly heat the air in the drying duct, thereby improving the drying efficiency.

[0029] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the clothes processing device is provided with a condensed water inlet that can be controlled to be opened and closed, and the condensed water can condense the drying airflow discharged from the processing drum;

[0030] The method further comprises:

[0031] When the condensation function needs to be started, the condensation water inlet is controlled to be opened, and when the condensation function needs to be turned off, the condensation water inlet is controlled to be closed.

[0032] With this implementation method, the condensation function is realized by water condensation. The condensation function can be turned on and off by controlling the opening and closing of the condensation water inlet. The control method is simple and convenient.

[0036] The double-suction fan comprises a volute, an impeller and a driving motor driving the impeller to rotate, the volute is provided with a volute air inlet, a volute air outlet and an air vent, wherein the volute air inlet is used for allowing the drying air flow inside the drying air duct to enter, the volute air outlet is used for allowing the fluid in the double-suction fan to flow into the drying air duct, and the air vent is connected to the external environment of the clothes processing device, and is used to introduce fresh air into the drying air duct;

[0037] The vent can be controlled to open and close;

[0038] When the driving motor drives the impeller to rotate, the air from the external environment can be introduced into the cavity of the volute through the vent and mixed with the drying airflow entering the cavity through the volute air inlet, and the mixed airflow is discharged from the volute air outlet and flows to the heating section;

[0039] The heating section is provided with a heater for heating the drying airflow; the condensing section is provided with a condensing water inlet which can be controlled to be opened and closed.

[0040] By adopting this implementation mode, after the double-suction fan is installed in the drying air duct, the vent of the double-suction fan package can be connected to the external environment, so that after the impeller rotates, the air in the external environment is introduced into the drying air duct, so that the air volume in the drying air duct is increased, thereby increasing the air volume for drying clothes and improving the drying efficiency. In addition, the air introduced into the drying air duct is mixed with the original drying air flow in the drying air duct, which reduces the load of the fan, helps to increase the wind speed, improves the moisture carrying capacity of the load in the drying air duct, and further improves the drying efficiency.

[0041] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the impeller is rotatably disposed in the volute; the impeller includes a first blade structure and a second blade structure, the first blade structure and the second blade structure are connected side by side along the axial direction of the impeller and are synchronously driven by the drive motor; wherein the first blade structure is arranged close to the air vent for introducing air from the external environment into the double-suction fan, and the second blade structure is arranged close to the air inlet of the volute for introducing the drying airflow inside the drying air duct into the double-suction fan.

[0053] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0054] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0055] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0056] The electric heating clothes washing and drying device is mainly to open an air outlet at the rear drum position, connect the condenser, and directly or indirectly contact the hot and humid air with the low-temperature water entering the condenser to exchange heat and moisture, and separate the condensed water and low-temperature dry air. The low-temperature dry air is sucked by the fan through the heating device to dry the clothes, achieving the effect of drying and dehumidification. This setting method has a large fan load, and after the hot and humid air accumulates, the drying efficiency is low.

[0057] In order to reduce the fan load, a double-suction fan is used to introduce fresh air. However, in actual applications, excessive fresh air introduction will lower the temperature inside the barrel. If condensed water continues to enter, the evaporation rate will be lower than the condensation rate, resulting in a decrease in drying efficiency.

[0058] Based on this problem, the technical solution is to combine a double-suction fan structure and add a control method in the drying stage. By adjusting the opening and closing of the fresh air inlet and exhaust outlet in the heating stage, and adjusting the start and stop rhythm of the condensation water in the drying stage, the evaporation rate and the condensation rate are balanced, thereby further shortening the drying time.

[0059] Specifically, the embodiments of the present application solve at least the following problem:

[0060] 1. Adjust the start and stop rhythm of condensing water, increase the temperature in the barrel, and balance the evaporation rate and condensation rate.

[0061] 2. Realize the exchange of fresh air and hot and humid air to improve the drying efficiency of the air duct.

[0062] 3. Reduce the start and stop of electric heating and water consumption to save energy and electricity.

[0063] The embodiments of the present application include the following beneficial effects:

[0064] A control method is added during the drying stage to balance the evaporation rate and condensation rate by adjusting the opening and closing of the fresh air inlet and exhaust vents during the heating stage, and adjusting the start and stop rhythm of the condensation water during the drying stage, thereby further shortening the drying time.

[0065] The embodiments of the present application include the following features:

[0066] This technical solution is combined with a control method for a double-suction fan design, wherein the double-suction fan can be a double-suction fan, that is, a fan that can inhale both drying airflow and external ambient air. It can further increase the temperature in the barrel during the drying stage to prevent the problem of a reduced evaporation rate due to the inability to increase the temperature in the barrel after the introduction of fresh air. The start and stop rhythm of the condensed water is controlled to stabilize the inlet air temperature within a certain range. This can further reduce water and electricity consumption while improving the drying efficiency, thereby saving energy and being environmentally friendly.

[0067] Based on this, an embodiment of the present application provides a drying method, which is applied to a clothes processing device with a drying function, wherein the clothes processing device includes a processing drum and a drying air duct, wherein a heater and a double-suction fan are arranged in the drying air duct, and a drying air flow circulates between the processing drum and the drying air duct under the agitation of the double-suction fan, wherein the double-suction fan is further used for introducing fresh air into the drying air duct, and the heater is used for heating the drying air flow, Figure 1The schematic flow chart of the drying method shown in FIG. 1 includes the following processing steps.

[0068] S100. In the condensation stage, the dual-suction fan is controlled to start, the heater is kept in an on state, and the condensation function of the clothes processing equipment is started.

[0069] The condensation function can condense the drying airflow after it is activated. Specifically, the condensation means can be water condensation, that is, by providing a condensation water inlet, condensation water is transported into the clothing processing device, and the drying airflow can contact with the condensation water during the flow process to be condensed.

[0070] In one embodiment, when the airflow temperature of the drying airflow entering the processing drum exceeds a preset first temperature threshold, it is determined to be in the condensation stage.

[0071] Wherein, a temperature sensing bag is arranged at the air inlet of the processing tube, and the temperature detected by the temperature sensing bag is the air flow temperature.

[0072] It should be noted that the airflow temperature needs to be detected periodically on a continuous basis, and the airflow temperature can be continuously obtained by setting a detection period.

[0073] In one embodiment, the first temperature threshold is set according to the temperature at which the drying airflow can dry the clothes. That is to say, during drying, the drying airflow will be heated up first. When the temperature is raised to the first temperature threshold, it is determined that the clothes can be dried. Therefore, this embodiment does not limit the specific value of the first temperature threshold.

[0074] When the double suction fan is started, it can introduce fresh air and promote the flow of dry air in the drying duct. When the heater is turned on, it can heat the air in the drying duct. When the condensation function is started, it can condense the dry air, thereby reducing the humidity of the dry air.

[0075] S102: After the condensation function is started, the on / off state of the condensation function is adjusted according to the periodically acquired air flow temperature to balance the condensation rate and the evaporation rate.

[0076] Wherein, the start and close conditions include the start time and / or the shut down time of the condensing function;

[0077] The step of adjusting the on / off state of the condensation function according to the periodically acquired airflow temperature includes:

[0078] As the air flow temperature increases, the start-up time is increased and / or the shut-down time is decreased.

[0079] That is to say, after the condensation function is started, the airflow temperature of the drying airflow entering the processing cylinder will be continuously obtained, and the opening and closing of the condensation function will be adjusted according to the currently obtained airflow temperature.

[0080] The start and close conditions include start and close conditions, preferably the length of the start time and the length of the close time.

[0081] It should be noted that the double-suction fan can also be replaced by two independent fans, one of which is used to actuate the drying airflow, and the other is used to introduce fresh air.

[0082] According to this embodiment, the air flow temperature of the drying air flow in the processing cylinder is monitored and the opening and closing of the condensation function is adjusted so that the condensation rate and the evaporation rate are balanced, thereby improving the drying efficiency.

[0083] In a possible embodiment of the present application, after the condensing function is started, the start time and / or the shut down time of the condensing function is adjusted according to the size of the air flow temperature obtained periodically.

[0084] The on time refers to the length of time the condensing function is on, and the off time refers to the length of time the condensing function is off.

[0085] For ease of understanding, in one embodiment, the condensing function has a start-and-stop rhythm, that is, the condensing function repeatedly switches between a start state and a stop state, and when the start time and / or the stop time changes, the start-and-stop rhythm of the condensing function changes accordingly.

[0086] By adopting this implementation method, when balancing the condensation rate and the evaporation rate, only the on / off status of the condensation function is controlled, which helps to reduce the control amount and the calculation amount.

[0087] Optionally, in an implementation of this embodiment, increasing the startup time and / or decreasing the shutdown time as the airflow temperature increases includes:

[0088] The proportion of the startup time increases as the temperature range of the airflow temperature increases, and / or the proportion of the shutdown time decreases as the airflow temperature increases, wherein the proportion of the startup time refers to the ratio of the startup time to the sum of the startup time and the shutdown time, and the proportion of the shutdown time refers to the ratio of the shutdown time to the sum of the startup time and the shutdown time.

[0089] In one embodiment, the start time may also be increased as the air flow temperature increases, and the shut down time may be decreased as the air flow temperature increases. Since the air flow temperature is obtained periodically, when determining whether to increase the start time or decrease the shut down time, the air flow temperature is determined to be increased or decreased based on the comparison between the air flow temperature obtained at the current moment and the air flow temperature obtained at the previous moment, thereby adjusting the start time and / or shut down time.

[0090] For ease of understanding, for example, when the time reaches 1 o'clock, the air flow temperature obtained is 40 degrees Celsius, and at 1:01, the air flow temperature obtained is 42 degrees Celsius. Since 42 is greater than 40, the air flow temperature increases, and the start time is increased and / or the shutdown time is reduced.

[0091] In another embodiment, as long as the airflow temperature exceeds a certain set value, it is determined that the change direction of the airflow temperature is increasing, and the start time is increased and / or the shutdown time is decreased.

[0092] Accordingly, the start-up time decreases as the periodically acquired airflow temperature decreases, and / or the shut-down time increases as the periodically acquired airflow temperature increases.

[0093] With this implementation, when the airflow temperature increases, the evaporation rate increases. At this time, increasing the startup time helps to increase the condensation rate, thereby balancing the condensation rate and the evaporation rate and improving the drying efficiency. Similarly, the shutdown time can be reduced to balance the condensation rate and the evaporation rate and improve the drying efficiency.

[0094] Optionally, in an implementation of this embodiment, the method further includes:

[0095] If the airflow temperature obtained periodically exceeds a preset second temperature threshold, the start time is increased and the shutdown time is decreased, wherein, among the airflow temperatures obtained periodically, each time one of the airflow temperatures exceeds the second temperature threshold, the start time is increased once and the shutdown time is decreased once;

[0096] If the periodically acquired airflow temperature is between the second temperature threshold and the first temperature threshold, the startup time is increased, wherein, among the periodically acquired airflow temperatures, each time there is an airflow temperature between the second temperature threshold and the first temperature threshold, the startup time is increased once;

[0097] If the airflow temperature obtained periodically is lower than the first temperature threshold, the startup time is reduced, wherein, among the airflow temperatures obtained periodically, each time one of the airflow temperatures is lower than the first temperature threshold, the startup time is reduced once;

[0098] The first temperature threshold is lower than the second temperature threshold.

[0099] In one embodiment, the start time changes by 5 seconds each time, and the close time changes by 5 seconds each time. When the close time is 0 seconds, the condensing function is in a normally open state.

[0100] By adopting this implementation method, the air flow temperature is monitored by setting the first temperature threshold and the second temperature threshold. As the number of air flow temperature detections increases, the number of adjustments to the on and off conditions of the condensation function will also increase accordingly, which is beneficial to improving the balance efficiency between the condensation rate and the evaporation rate, thereby improving the drying efficiency.

[0101] Optionally, in an implementation of this embodiment, after the condensation function is started, the method further includes:

[0102] If the proportion of the startup time exceeds a preset ratio threshold or the shutdown time is zero, the heating power of the heater is reduced when the startup time needs to be increased, and the heating power of the heater is increased when the shutdown time needs to be reduced.

[0103] By adopting this implementation, in addition to adjusting the start and stop time of the condensation function, the heating power of the heater can also be adjusted, which helps to improve the balance efficiency between the condensation rate and the evaporation rate, thereby improving the drying efficiency.

[0104] Optionally, in an implementation of this embodiment, the drying air duct is provided with an exhaust port that can be controlled to be opened and closed, and the method further includes:

[0105] If the air flow temperature exceeds a preset first temperature threshold, the exhaust port is controlled to open.

[0106] In one embodiment, the air outlet can discharge the airflow in the drying air duct out of the drying air duct.

[0107] With this implementation, the air outlet helps to balance the air pressure in the drying air duct.

[0108] Optionally, in an implementation of this embodiment, the method further includes:

[0109] During the temperature rising stage of the drying airflow, the fresh air inlet and the air outlet of the double-suction fan are controlled to be closed.

[0110] In one embodiment, when the temperature of the drying airflow reaches a first temperature threshold, it is proved that the heating stage ends and enters the condensation stage, so as to execute control to start the double suction fan, keep the heater in the on state, and start the condensation function of the clothes processing device, and after the condensation function is started, adjust the opening and closing of at least one of the condensation function, the heater and the double suction fan according to the periodically obtained airflow temperature to balance the condensation rate and the evaporation rate. The heating stage refers to the stage of heating the drying airflow to the first temperature threshold.

[0111] With this implementation, after the fresh air inlet and outlet are closed, air from the external environment is not easy to enter the drying duct, so that the heater can quickly heat the air in the drying duct, thereby improving the drying efficiency.

[0112] Optionally, in an implementation of this embodiment, the clothes processing device is provided with a condensed water inlet which can be controlled to be opened and closed, and the condensed water can condense the drying airflow discharged from the processing drum;

[0113] The method further comprises:

[0114] When the condensation function needs to be started, the condensation water inlet is controlled to be opened, and when the condensation function needs to be turned off, the condensation water inlet is controlled to be closed.

[0115] With this implementation method, the condensation function is realized by water condensation. The condensation function can be turned on and off by controlling the opening and closing of the condensation water inlet. The control method is simple and convenient.

[0116] An embodiment of the present application also provides a control method for a clothing processing device, and the control method includes the drying method described above.

[0117] An embodiment of the present application also provides a clothing processing device, which adopts the above-mentioned drying method or the above-mentioned control method.

[0118] Optionally, in an implementation of this embodiment, as Figure 2-5 As shown, the clothes processing device includes a processing drum and a drying air duct 8, the drying air duct 8 includes a condensing section and a heating section, and a double suction fan is provided between the condensing section and the heating section;

[0119] The double-suction fan comprises a volute, an impeller 3 and a driving motor driving the impeller 3 to rotate, the volute is provided with a volute air inlet, a volute air outlet and an air vent, wherein the volute air inlet is used for allowing the drying airflow inside the drying air duct 8 to enter, the volute air outlet is used for allowing the fluid in the double-suction fan 1 to flow into the drying air duct 8, and the air vent is connected to the external environment of the clothing processing device, and is used to introduce fresh air into the drying air duct 8;

[0120] The vent can be controlled to open and close;

[0121] When the driving motor drives the impeller 3 to rotate, the air from the external environment can be introduced into the cavity of the volute through the vent and mixed with the drying airflow entering the cavity through the volute air inlet, and the mixed airflow is discharged from the volute air outlet and flows to the heating section;

[0122] The heating section is provided with a heater for heating the drying airflow; the condensing section is provided with a condensing water inlet which can be controlled to be opened and closed.

[0123] In one embodiment, the impeller 3 is rotatably connected to the volute via a bearing, that is, the impeller 3 and the volute can move relative to each other, the impeller 3 rotates, but the volute does not rotate. In another embodiment, the impeller 3 is not connected to the volute, but is only located inside the volute, and the impeller 3 rotates inside the volute by connecting to a driving mechanism. This embodiment does not specifically limit whether the impeller 3 is connected to the volute and how it is connected, and it is intended that the impeller 3 is located inside the volute.

[0124] The driving mechanism is arranged in the driving mechanism cover 2 .

[0125] After the double suction fan is started, the drying airflow in the drying air duct 8 flows from the condensing section to the heating section, and then moves into the clothes processing barrel. After contacting the clothes in the clothes processing barrel, it moves to the condensing section again, and the cycle repeats.

[0126] By adopting this implementation mode, after the double suction fan is installed in the drying air duct 8, the vent of the double suction fan package can be connected with the external environment, so that after the impeller 3 rotates, the air in the external environment is introduced into the drying air duct 8, so that the air volume in the drying air duct 8 is increased, thereby increasing the air volume for drying clothes and improving the drying efficiency. In addition, the air introduced into the drying air duct 8 is mixed with the original drying air flow in the drying air duct 8, which reduces the load of the fan, helps to increase the wind speed, improves the moisture carrying capacity of the load in the drying air duct 8, and further improves the drying efficiency.

[0127] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the impeller 3 is rotatably arranged in the volute; the impeller 3 includes a first blade structure 31 and a second blade structure 32, and the first blade structure 31 and the second blade structure 32 are connected side by side along the axial direction of the impeller 3 and are synchronously driven by the drive motor; wherein the first blade structure 31 is arranged close to the air vent for introducing air from the external environment into the double-suction fan 1, and the second blade structure 32 is arranged close to the volute air inlet for introducing the drying airflow inside the drying air duct 8 into the double-suction fan 1.

[0128] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the impeller 3 is provided with an annular fan blade partition 4, and the first fan blade structure 31 and the second fan blade structure 32 are fixed on both sides of the fan blade partition 4; the first fan blade structure 31 includes a plurality of first blades; the second fan blade structure 32 includes a plurality of second blades; the plurality of first blades are arranged in a ring shape and are fixedly connected at equal intervals on the first surface of the fan blade partition 4; the plurality of second blades are arranged in a ring shape and are fixedly connected at equal intervals on the second surface of the fan blade partition 4; the ring formed by the plurality of first blades is coaxial with the ring formed by the plurality of second blades; the length of the first blade is less than the length of the second blade.

[0129] In one embodiment, after the first fan blade structure 31 and the second fan blade structure 32 rotate, they guide the air, form airflow and encourage the airflow to move in a fixed direction. Since a vent is provided on the wall of the volute relative to the first fan blade structure 31, when the first fan blade structure 31 rotates, the air outside the vent is introduced into the volute to form fresh air.

[0130] In one embodiment, the first fan blade structure 31 and the second fan blade structure 32 are both fixedly connected to the fan blade partition 4. In one embodiment, the fixed connection is achieved by welding; in other embodiments, the fixed connection is achieved by gluing or interference fit, etc., which is not specifically limited in this embodiment.

[0131] In one embodiment, the number of the first blades may be the same as the number of the second blades, or may be different from the number of the second blades, and this embodiment does not specifically limit this. Since the number of blades affects the amount of air guided, if a large amount of fresh air is actually required, the number of the first blades is greater than the number of the second blades, and if a small amount of fresh air is actually required, the number of the first blades is less than the number of the second blades.

[0132] In one embodiment, the ring is a circular ring, that is, a ring with a circular cross section. In other embodiments, the ring is a rectangular or irregular shape, as long as it is a closed and hollow shape.

[0133] Specifically, in one embodiment, the length of the first blade is between one half and one tenth of the length of the second blade, and preferably the length of the first blade is one quarter of the length of the second blade.

[0134] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the drying air duct 8 is connected to a ventilation pipe 11, the ventilation pipe 11 is connected to an exhaust duct 12, and the exhaust duct 12 is connected to the external environment.

[0135] By adopting this implementation method, pressure relief is easy.

[0136] Optionally, in an implementation of this embodiment, the clothing processing device includes at least one of a dryer and a washer-dryer.

[0137] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0138] In a specific implementation of the embodiment of the present application, the drying method includes the following processing steps:

[0139] like Figure 6 As shown, in the heating stage, the electric heater 9 is turned on. At this stage, the electric heater 9 device will start to quickly increase the temperature in the barrel. At the same time, in order to ensure that the temperature can rise quickly, the condensation water switch will be turned off, and the fresh air inlet and exhaust port 13 will also be closed. This closed environment can effectively reduce the interference of the outside air and quickly increase the temperature in the barrel. The main purpose of this process is to evaporate the moisture in the barrel and prepare for the subsequent condensation process.

[0140] When the temperature in the barrel gradually rises and reaches the preset standard temperature T1, it enters the condensation stage, the condensing water is turned on, and the initial opening time t0 is less than or equal to the closing time t1, that is, t0≤t1. At this time, the inlet air temperature continues to rise and condensation begins. When the inlet air temperature rises to T2, the opening time t0 of the condensing water is gradually extended, the closing time t1 is gradually reduced, and the inlet air temperature is continuously monitored. If the inlet air temperature exceeds the standard temperature T1, the opening time of the condensing water will continue to be extended to ensure that the moisture can be fully condensed and discharged. Conversely, if the inlet air temperature drops below the standard temperature T1, the opening time of the condensing water will be reduced to avoid energy waste and other adverse effects caused by excessive condensation. Through this dynamic adjustment, the equipment can maintain the best operating state under different temperature conditions, ensuring the effective treatment of moisture and the stable operation of the equipment.

[0141] During the cooling stage, the fresh air inlet and exhaust vents are all opened at the same time to quickly cool down and allow water vapor to evaporate quickly.

[0142] The double-blade fan introduces fresh air to improve drying efficiency. Under the condition of ensuring a small water flow, a good drying effect is obtained, and the utilization rate of low-temperature water is improved. At the same time, by controlling the start and stop of condensed water, the temperature of the incoming air and the barrel can be maintained within a suitable range, and the electric heating is kept on 9 times to save water and energy.

[0143] This technical solution connects the vent pipe to an exhaust duct to introduce fresh air and exhausts the air when the pressure is too high. Figure 5 One end of the exhaust pipe 12 is connected to the air vent pipe 11, and the other end is connected to the box body 5, and the position of the connection with the box body 5 is not limited.

[0144] In this technical solution, the condensing water opening time t0 is extended by +5s each time, and t1 is reduced by -5s each time. When the temperature continues to rise, the condensing water opening time continues to extend, and t1 continues to decrease to 0s, then it is the condensing water normally open mode.
