[0575] Compared with the prior art, the beneficial effects of the present invention are mainly:

[0576] The fan blade mechanism is provided with a first section and a second section of variable length. Since the fan blade is divided into two sections, the first section and the second section can introduce airflow in different directions during the rotation of the fan blade. As a result, the first section can introduce fresh air outside the air duct where the fan is located, so that when drying clothes, the air volume of the fresh air in the air duct where the fan is located can be increased or reduced by adjusting the position of the second fan blade partition. The fresh air flows along with the original circulating air in the air duct where the fan is located, reducing the load of the fan, while helping to increase the wind speed and improve the moisture carrying capacity of the load in the air duct, thereby improving the drying efficiency;

[0577] The double-suction centrifugal fan includes an impeller, which includes a first blade structure and a second blade structure, wherein the first blade structure is opposite to an opening on the volute wall, and the opening is connected to the external gas of the volute, so that the external fresh air can enter the volute based on the first blade structure. The fresh air in the volute follows the original air flow in the 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 air duct, and further improves the drying efficiency;

[0578] In the preset mode of the drying system, the ambient air parameters outside the clothes processing drum and the uncooled drying air flow parameters inside the drying system are obtained and compared to determine whether a large amount of condensation will be generated when the drying air flow is discharged to the outside and contacts the ambient air. Then, the discharge speed and / or discharge rhythm of the drying air flow are adjusted according to the comparison result, so that the drying air flow can be fully condensed and cooled in the drying system before being discharged. This can avoid that after the drying air flow is discharged from the drum, a large amount of condensation will be generated when it encounters the ambient air with a large temperature difference due to its high temperature and high humidity, thus affecting the user experience of the customer.

[0579] The top of the ventilation pipe is connected to the water inlet pipe and the exhaust pipe respectively. When the temperature of the gas in the ventilation pipe is high or the humidity is high, condensed water can be injected into the ventilation pipe through the water inlet pipe, so that the gas in the ventilation pipe can be condensed by the condensed water while being discharged through the exhaust pipe, so that the temperature and humidity of the gas discharged from the ventilation pipe can be controlled, and it is prevented that the gas with high temperature and high humidity is directly discharged from the ventilation pipe to form a large amount of water vapor, which affects the customer's use experience;

[0580] A filter assembly is provided in an embodiment of the present invention, which is provided with two filter elements. By driving one of the filter elements to rotate relative to the other filter element, on the one hand, the filtering effect of the filter assembly can be changed, and on the other hand, the air volume passing through the filter assembly per unit time can also be changed.

[0581] In the embodiment of the present invention, the existing fan system in the clothing processing device is changed into a double suction fan, the second air suction port of the double suction fan is outside the air duct system, used to introduce fresh air, and the first air suction port is inside the air duct system, used to inhale the airflow in the clothing processing drum. At the same time, an angle-adjustable window blade structure is installed at the fresh air inlet position of the double suction fan, which can ensure that the change of the fresh air volume introduced can be achieved while the original internal circulation air volume remains unchanged.

[0582] In the embodiment of the present invention, the volatile device is placed outside the clothing treatment drum and combined with the air intake principle of the double-suction fan. On the one hand, when the double-suction fan is running, the fresh air inlet of the double-suction fan can be used to introduce fresh air and at the same time suck in scented air to act on the surface of the clothes in the clothing treatment drum, thereby improving the fragrance retention effect of the clothes. On the other hand, when the double-suction fan is not running, the volatile device can also be used as an environmental fragrance through volatilization, thereby improving the utilization rate of the volatile device.

[0583] In the embodiment of the present invention, a fresh air inlet is provided on the fan, so that the drying efficiency of the clothing processing equipment can be improved. At the same time, a condensation box is provided, so that the hot and humid air of the clothing processing equipment can be discharged into the condensation box for condensation and then discharged to the outside, thereby achieving a balanced air pressure in the barrel while further improving the drying efficiency and avoiding condensation in the water box in the clothing processing equipment. Furthermore, since fresh air is introduced during drying, the temperature rise in the clothing processing drum of the clothing processing equipment in the early stage of drying becomes slower. In order to further improve the drying efficiency and achieve a water-saving effect, a temperature sensor for detecting the temperature in the clothing processing drum is provided in the embodiment of the present invention, and can control the water inlet or stop the water inlet of the condensation box according to the temperature value in the clothing processing drum, thereby achieving a water-saving effect while improving the drying efficiency.

[0585] The fan blade cavity is connected to the first air duct section and the second air duct section. An opening is formed on the side wall of the fan blade cavity. The opening connects the ventilation blade cavity and the external environment where the drying fan is located. The fresh air from the external environment can enter the fan blade cavity through the opening and mix with the drying airflow flowing through the fan blade cavity, thereby reducing the humidity of the drying airflow and improving the quality of the drying airflow; accelerating the evaporation of moisture in clothes, shortening the drying time, and improving the drying efficiency; reducing the load of the drying fan and saving energy;

[0693] It should be understood that the term "and / or" used 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 represent: A exists alone, A and B exist at the same time, and B exists alone.

[0694] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0695] In the prior art, the structural design of the drying system is unreasonable, resulting in insufficient contact between the drying airflow and the condensed water, small heat exchange area, low condensation efficiency and long drying time;

[0696] The present invention creatively provides a clothes processing device, comprising an outer drum and a drying system; the outer drum is formed with a drying air inlet and a drying air outlet; the drying system is connected between the drying air inlet and the drying air outlet and the drying system comprises a condensing air duct and a heating air duct and a drying fan connecting the condensing air duct and the heating air duct, the drying fan is a double-suction fan, and the drying fan is used to provide power to the drying airflow; the condensing air duct comprises an outer condensing air duct formed on the outer side of the rear wall of the outer drum and an inner condensing air duct formed on the inner side of the rear wall of the outer drum;

[0697] While ensuring that less condensed water is required, the drying effect is improved, the utilization rate of condensed water is increased, and water and energy are saved; the load of the drying fan 5 is reduced, and the accumulation of humidity in the drying airflow is avoided; the fresh air in the environment where the clothing processing equipment is located can enter the fan cavity and mix with the drying airflow, and the introduction of fresh air can improve the quality of the drying airflow; the drying airflow is in full contact with the condensed water, the heat exchange area is large, and the condensation efficiency is high.

[0698] Example 1

[0699] like Figure 1a-Figure 1e As shown, the embodiment of the present application discloses a double-suction centrifugal fan, including a volute 13, an impeller 3 rotatably disposed in the volute 13, and a driving motor 22 capable of driving the impeller 3 to rotate;

[0700] The impeller 3 includes a first fan blade structure 31 and a second fan blade structure 32; the first fan blade structure 31 and the second fan blade structure 32 are connected side by side along the axial direction of the impeller 3 and are synchronously driven by the driving motor 22;

[0701] The volute 13 is provided with an air inlet and an air outlet, the air inlet and the air outlet are used to communicate with the first fluid medium channel, the impeller 3 is located between the air inlet and the air outlet, and the first fan blade structure 31 and the second fan blade structure 32 are both in communication with the air inlet and the air outlet inside the volute 13;

[0702] The volute 13 is further provided with an opening 131 on the wall of the volute 13 axially opposite to the first fan blade structure 31. One end of the opening 131 is in communication with the external gas of the volute 13, and the other end is in communication with the internal gas of the volute 13.

[0703] The first fan blade structure 31 is disposed near the opening 131 and its fan blades have first blade parameters adapted to the air entering the opening 131 . The second fan blade structure 32 is disposed near the air inlet and its fan blades have second blade parameters adapted to the air entering the air inlet.

[0704] In one embodiment, the parameters of the wind blade refer to the length of the wind blade, the twist angle, the airfoil, the area of ​​the wind blade, and the chord length of the wind blade. The parameters of the wind blade include the length of the wind blade, the twist angle, the airfoil, the area of ​​the wind blade, and the chord length of the wind blade. These indices must be used in the operation and maintenance of the wind farm. The length of the wind blade refers to the length of the skeleton line of the wind blade. The chord length of the wind blade airfoil in each radial section of the wind blade is called the root chord, and the chord length of the airfoil in the tip section of the wind blade is called the tip chord. The twist angle refers to the blade angle. The blade angle (propellerbladeangle), also known as the twist angle of the blade, refers to the angle between the propeller chord line and the propeller rotation plane. It changes with the radius, and its change law is the most important factor affecting the working performance of the propeller.

[0705] The impeller 3 is disposed in the volute 13. In one embodiment, the impeller 3 is rotatably connected to the volute 13 via a bearing, that is, the impeller 3 and the volute 13 can move relative to each other, the impeller 3 rotates, but the volute 13 does not rotate. In another embodiment, the impeller 3 is not connected to the volute 13, but is only located inside the volute 13, and the impeller 3 rotates inside the volute 13 by connecting to a driving mechanism. This embodiment does not specifically limit whether the impeller 3 is connected to the volute 13 and how to connect, and it is intended that the impeller 3 is located inside the volute 13.

[0706] 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. In particular, since the volute 13 has an opening 131 on the wall relative to the first fan blade structure 31, when the first fan blade structure 31 rotates, the air outside the opening 131 will be introduced into the volute 13 to form fresh air.

[0707] Through the above steps, the double-suction centrifugal fan 1 includes an impeller 3, and the impeller 3 includes a first blade structure 31 and a second blade structure 32, wherein the first blade structure 31 is opposite to the opening 131 on the wall of the volute 13, and the opening 131 is connected to the external air of the volute 13, so that the external fresh air can enter the volute 13 based on the first blade structure 31. The fresh air in the volute 13 follows the original air flow in the air duct, which reduces the load of the fan, helps to increase the wind speed, improves the wet carrying capacity of the load in the air duct, and further improves the drying efficiency.

[0708] In another 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;

[0709] The first fan blade structure 31 includes a plurality of first blades; the second fan blade structure 32 includes a plurality of second blades;

[0710] A plurality of first blades are arranged in a ring shape and fixedly connected to the first surface of the fan blade partition 4 at equal intervals;

[0711] A plurality of second blades are arranged in a ring shape and fixedly connected to the second surface of the fan blade partition 4 at equal intervals;

[0712] The ring formed by the arrangement of the plurality of first blades is coaxial with the ring formed by the arrangement of the plurality of second blades;

[0713] The length of the first blade is smaller than the length of the second blade.

[0714] 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.

[0715] 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.

[0716] In one embodiment, the ring is a circular ring, that is, a ring with a cross section that is a prototype. In other embodiments, the ring is a rectangular or irregular shape, as long as it is a closed and hollow shape.

[0717] 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.

[0718] Through the above steps, there are multiple first blades and second blades, and they are evenly spaced on the fan blade partition 4, so that when the number of first blades or the number of second blades needs to be increased, the first blade to be added can be inserted between two adjacent first blades, and still maintain an equal distance. The same is true for adding second blades, so that the added fan blades are not likely to affect the formation of airflow by the double-suction centrifugal fan 1, nor to increase the noise generated by the double-suction centrifugal fan 1, thereby improving the convenience of adding fan blades.

[0719] In another embodiment of the present application, the bending angle of the first blade is different from the bending angle of the second blade; the airflow inlet direction and the airflow outlet direction of the first blade are different from those of the second blade.

[0720] The bending angle refers to the curvature of the blade, and different bending angles have different wind guiding capabilities. Specifically, in one embodiment, the bending angle of the first blade is greater than the bending angle of the second blade. The first blade and the second blade have different wind guiding capabilities, which facilitates controlling the difference between the amount of fresh air introduced and the amount of airflow in the air duct, thereby controlling the drying effect.

[0721] The air flow inlet direction and the air flow outlet direction can be adjusted by changing the orientation of the fan blades.

[0722] Through the above steps, by utilizing the different bending angles and directions, it is convenient to control the difference in the guided air volume between the first fan blade structure 31 and the second fan blade structure 32, thereby making the double-suction centrifugal fan 1 more in line with the use requirements.

[0723] In another embodiment of the present application, the difference between the twist angle in the first blade parameter and the twist angle in the second blade parameter is less than 30 degrees. Specifically, in one embodiment, the twist angle of the second blade is preferably 45 degrees, the twist angle of the first blade is less than the twist angle of the second blade, and the difference is less than 30 degrees.

[0724] Through the above content, the torsion angle affects the amount of introduced fluid, and by limiting the difference between the torsion angles of the first blade and the second blade, it is convenient to ensure that the fluid stably enters the volute 13.

[0725] In another embodiment of the present application, a drive mechanism cover 2 is provided on the wall of the volute 13 opposite to the first wind blade structure 31; the drive mechanism cover 2 is connected to the volute 13 through a plurality of connecting arms; a gap is formed between the plurality of connecting arms, and the opening 131 is connected to the outside of the volute 13 through the gap.

[0726] In one embodiment, a drive mechanism cover 2 is provided on the volute 13, and the drive mechanism cover 2 includes a plurality of connecting arms, which are connected to the volute 13 by snapping, so that the drive mechanism cover 2 is fixed to the volute 13. Gaps are formed between adjacent connecting arms, and the gaps are connected to the opening 131 of the volute 13 and are also connected to the outside of the air duct where the double-suction centrifugal fan 1 is located, so as not to affect the entry of fresh air into the air duct.

[0727] It should be noted that the number and shape of the connecting arms and the connection method with the volute 13 are not specifically limited in this embodiment.

[0728] In one embodiment, the side edge of the connecting arm is inclined relative to the surface of the volute 13 where the opening 131 is formed.

[0729] Through the above steps, the driving mechanism cover 2 is connected to the volute 13, which makes it easy to install the double-suction centrifugal fan 1 using the driving mechanism cover 2, so that the double-suction centrifugal fan 1 is easy to install and has high stability.

[0730] In another embodiment of the present application, a guide ring 21 connected to the volute 13 is provided at the opening 131 of the volute 13 .

[0731] In one embodiment, the guide ring 21 is annular, and the height of the end surface of the guide ring 21 away from the first fan blade structure 31 is higher than the height of the surface of the volute 13. That is, this embodiment does not limit the specific shape of the guide ring 21, and aims to use the guide ring 21 to guide the external air into the volute 13 to form fresh air.

[0732] Through the above steps, the guide ring 21 enables the first fan blade structure 31 to rotate, so that fresh air can be introduced into the volute 13, and the amount and efficiency of the introduced fresh air are improved.

[0733] In another embodiment of the present application, a damper is provided above the opening 131 of the volute 13 for opening and closing the opening 131 .

[0734] Through the above content, by opening and closing the damper, it is convenient to control the opening and closing of the opening 131, thereby controlling whether fresh air is introduced, so as to meet different fan usage requirements.

[0735] The embodiment of the present application also provides a drying system, as shown in Figure 5, comprising a clothing processing barrel and a drying duct connected to the clothing processing barrel, an internal circulation drying airflow flows between the drying duct and the clothing processing barrel; the drying duct is provided with a condensing device and a heating device, and the drying airflow flows through the condensing device after flowing out of the clothing processing barrel, and then flows into the heating device; the drying duct is provided with the above-mentioned double-suction centrifugal fan 1, and the double-suction centrifugal fan 1 is located between the condensing device and the heating device; when the driving motor drives the impeller 3 to rotate, the external ambient air of the clothing processing barrel can be introduced into the cavity of the volute 13 through the opening 131 and mixed with the internal circulation drying airflow entering the cavity of the volute 13 through the air inlet, and the mixed airflow is discharged from the air outlet to flow to the heating device.

[0736] In one embodiment, a condensing section and a heating section are provided in the drying air duct, the condensing section is provided with a condensing device, the heating section is provided with a heating device, and the double-suction centrifugal fan 1 is located between the condensing device and the heating device. When the driving motor 22 drives the impeller to rotate, the external ambient air of the clothes processing barrel can be introduced into the cavity of the volute 13 through the opening 131 and mixed with the internal circulation drying airflow entering the cavity of the volute 13 through the second air inlet, and the mixed airflow is discharged from the second air outlet to flow to the heating device.

[0737] In one embodiment, the drying system is provided with a fresh air mode. In the fresh air mode, the external fresh air introduced into the volute 13 from the opening 131 is blown out through the first fan blade structure 31 and mixed with the drying airflow that enters the volute 13 from the condensation section and is blown out through the second fan blade structure 32. The mixed airflow flows out from the air outlet and flows to the heating section.

[0738] In one embodiment, an openable and closable damper is provided above the opening 131 and / or a baffle capable of adjusting the flow area of ​​the drying air duct is provided on the air inlet side of the condensing device of the drying air duct.

[0739] In one embodiment, the double-suction centrifugal fan is located on the horizontal section of the drying air duct between the condensing device and the heating device; the axial direction of the impeller is perpendicular to the horizontal extension direction of the drying air duct.

[0740] In one embodiment, the condensation section is a condensation air duct 8, and an electric heating device 10 is provided in the heating section. When the clothing processing device dries the clothing, the clothing is located in the inner drum 7, and the flow process of the airflow in the air duct is the inner drum 7, the outer drum 6, the condensation air duct 8, the double suction centrifugal fan 11, the electric heating device 10, and the inner drum 7. When the airflow passes through the double suction centrifugal fan 11, the double suction centrifugal fan 11 introduces the air outside the air duct, so that fresh air enters the air duct. After the fresh air merges with the original airflow in the air duct, the airflow in the air duct increases, and the airflow temperature is not easy to be too high. On the one hand, the hot and humid gas in the inner drum 7 is not easy to gather above the inner drum 7, which reduces the fan load and increases the evaporation rate of clothing moisture. On the other hand, it is convenient to use the fresh air to control the temperature of the gas in the air duct, so as to facilitate the care of the clothing, and the clothing is not easy to be damaged.

[0741] An embodiment of the present application also provides a clothing processing device, which is provided with the above-mentioned drying system.

[0742] Example 2

[0743] like Figure 2a-2f As shown, the embodiment of the present application provides a drying system, including a clothes processing barrel and a drying air duct 13 connected between an air inlet and an air outlet of the clothes processing barrel, wherein a drying airflow flows between the drying air duct 13 and the clothes processing barrel when the drying system is working;

[0744] The drying air duct 13 includes a condensing section and a heating section, and a double suction fan 1 is provided between the condensing section and the heating section;

[0745] The double-suction fan 1 includes a volute, an impeller 3, and a driving motor for driving the impeller 3 to rotate. The volute is provided with a volute air inlet, a volute air outlet, and a vent, wherein the volute air inlet is used for allowing the drying airflow inside the drying air duct 13 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 13, and the vent is connected to the external environment of the clothes processing barrel;

[0746] When the driving motor drives the impeller 3 to rotate, the external ambient air of the clothing processing barrel 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.

[0747] 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.

[0748] After the double suction fan 1 is started, the drying airflow in the drying air duct 13 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.

[0749] Through the above steps, after the double suction fan 1 is installed in the drying air duct 13, the vent of the double suction fan 1 can be connected to the external environment of the clothes processing barrel, so that after the impeller 3 rotates, the air in the external environment is introduced into the drying air duct 13, so that the air volume in the drying air duct 13 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 13 is mixed with the original drying air flow in the drying air duct 13, 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 13, and further improves the drying efficiency.

[0750] In another embodiment of the present application, the drying duct 13 is provided with a ventilation port in the condensation section, and the ventilation port connects the drying duct 13 with the external environment of the clothing processing barrel, and the vent is connected to the ventilation port accordingly.

[0751] The shapes and sizes of the ventilation ports and vents are not specifically limited in this embodiment, and the ventilation ports are provided so that the air outside the drying duct 13, that is, the air outside the clothes treatment barrel, can enter the drying duct 13. In order to increase the amount of air entering the external environment, a vent connected to the ventilation port is provided on the double suction fan 1, so that during the rotation of the impeller 3 in the double suction fan 1, the air outside the ventilation port can be introduced into the volute and mixed with the drying airflow.

[0752] Through the above steps, the opening of the ventilation port is helpful for installing the double-suction fan 1, ensuring that the air outside the drying air duct 13 can enter the drying air duct 13.

[0753] In another embodiment of the present application, a baffle is provided on one side of the double suction fan 1 close to the condensing section, and the baffle is located in the drying air duct 13 and connected to the side wall of the drying air duct 13;

[0754] When the baffle moves to a preset first position, the drying air duct 13 between the condensing section and the double-suction fan 1 is blocked; when the baffle moves to a preset second position, the drying air duct 13 between the condensing section and the double-suction fan 1 is opened.

[0755] In one embodiment, the baffle has the function of blocking the drying air duct 13, so that when the baffle is in the first position, no drying airflow flows into the volute air inlet of the double-suction fan 1, and the impeller 3 completely introduces the air outside the drying air duct 13 into the drying air duct 13, so that the drying air duct 13 is full of fresh air.

[0756] In order to balance the air pressure in the drying duct 13 and the clothes processing tub, the airflow after passing through the clothes processing tub is discharged through other discharge paths, which is not specifically limited in this embodiment.

[0757] Through the above steps, by setting the baffle, it is convenient to control the fresh air that continuously enters the external environment through the drying air duct 13, and no longer use the circulating airflow, thereby meeting the use requirements of the drying system.

[0758] In another embodiment of the present application, the second position includes a plurality of sub-positions, and when the baffle is located at different sub-positions, the opening of the drying air duct 13 between the condensation section and the double-suction fan 1 is different.

[0759] In one embodiment, different opening degrees result in different amounts of air entering the external environment, which helps to adjust the amount of fresh air entering the drying air duct 13 .

[0760] In another embodiment of the present application, the double-suction blower 1 is provided with a damper for opening and closing the vent.

[0761] Specifically, the present embodiment does not specifically limit the installation method and structure of the damper, as long as the damper can open and close the vent. For example, the damper is rotatably connected to the volute, and when the vent needs to be closed, the damper is rotated so that the damper closes the vent.

[0762] Through the above steps, by setting the air door, when it is not necessary to introduce air from the external environment into the drying air duct 13, the double-suction fan 1 only stirs the original drying airflow in the drying air duct 13.

[0763] In another embodiment of the present application, the drying system is provided with a fresh air mode. In the fresh air mode, the vent introduces external fresh air into the double suction fan 1 and mixes it with the drying airflow entering the double suction fan 1 from the condensing section. The mixed airflow flows out from the volute air outlet and flows to the heating section.

[0764] In another embodiment of the present application, a condensate inlet pipe 9 is provided on the drying air duct 13 between the condensation section and the double-suction fan 1, an electric heating device 10 is installed in the heating section, and a dehumidification device 11 and a steam device 12 are installed in the drying air duct 13 in the direction of the heating section away from the double-suction fan 1.

[0765] In one embodiment, the condensate inlet pipe 9 is convenient for providing condensate to the condensation section to meet the condensation demand and reduce the moisture content of the drying airflow in the drying air duct 13. The temperature of the drying airflow increases after passing through the electric heating device 10, the dehumidification device 11 is convenient for reducing the humidity of the drying airflow, and the steam device 12 is convenient for increasing the humidity of the drying airflow.

[0766] Through the above steps, the structure is simple, and the dehumidification device 11 and the steam device 12 are used to meet different usage requirements, thereby improving the functionality and usage experience of the drying system.

[0767] In another embodiment of the present application, the double-suction fan 1 includes a volute, an impeller 3 rotatably arranged in the volute, and a driving motor capable of driving the impeller 3 to rotate; the impeller 3 includes a first blade structure 31 and a second blade structure 32, 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 driving motor; wherein the first blade structure 31 is arranged close to the air vent for introducing the fluid outside the drying air duct 13 into the double-suction fan 1, and the second blade structure 32 is arranged close to the air inlet for introducing the fluid inside the drying air duct 13 into the double-suction fan 1.

[0768] In another 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 to the first surface of the fan blade partition 4 at equal intervals; the plurality of second blades are arranged in a ring shape and are fixedly connected to the second surface of the fan blade partition 4 at equal intervals; the ring formed by the arrangement of the plurality of first blades is coaxial with the ring formed by the arrangement of the plurality of second blades; the length of the first blade is less than the length of the second blade; the first blade and the second blade are arranged at intervals in the circumferential direction of the rotating shaft of the impeller 3, and the first fan blade structure 31 is arranged close to the opening and its fan blades have first blade parameters adapted to the air intake of the opening, and the second fan blade structure 32 is arranged close to the air inlet and its fan blades have second blade parameters adapted to the air intake of the air inlet.

[0769] In one embodiment, the wind blade parameters refer to blade length, twist angle, airfoil, blade area, and blade chord length. The parameters of the blade include blade length, twist angle, airfoil, blade area, and blade chord length. These indices must be used in the operation and maintenance of wind farms. Blade length refers to the length of the blade's skeleton. Blade chord length: the chord length of the airfoil in each radial section of the blade. The chord length of the airfoil at the root section of the blade is called the root chord, and the chord length of the airfoil at the tip section of the blade is called the tip chord. The twist angle refers to the blade angle. The blade angle (propellerbladeangle), also known as the twist angle of the blade, refers to the angle between the propeller chord line and the propeller rotation plane. It changes with the radius, and its change pattern is the most important factor affecting the working performance of the propeller.

[0770] The impeller 3 is disposed in the volute. 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. 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 the purpose is that the impeller 3 is located inside the volute.

[0771] After the first fan blade structure 31 and the second fan blade structure 32 rotate, they guide the air, forming an airflow and driving the airflow to move in a fixed direction. Since a vent hole 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 hole is introduced into the volute to form fresh air.

[0772] 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.

[0773] 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.

[0774] In one embodiment, the ring is a circular ring, that is, a ring with a cross section that is a prototype. In other embodiments, the ring is a rectangular or irregular shape, as long as it is a closed and hollow shape.

[0775] 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.

[0776] In another embodiment of the present application, the bending angle of the first blade is different from the bending angle of the second blade; the airflow inlet direction and the airflow outlet direction of the first blade are different from those of the second blade.

[0777] Among them, the bending angle refers to the curvature of the blade. Different bending angles have different wind guiding capabilities. The wind guiding capabilities of the first blade and the second blade are different, which is convenient for controlling the difference between the amount of fresh air introduced and the flow of air in the air duct, thereby controlling the drying effect.

[0778] The airflow inlet direction and the airflow outlet direction can be adjusted by changing the orientation of the blades.

[0779] Through the above steps, by utilizing the different bending angles and directions, it is convenient to control the difference in the amount of air guided between the first fan blade structure 3131 and the second fan blade structure 32, thereby making the double-suction fan 1 more in line with usage requirements.

[0780] In another embodiment of the present application, the difference between the torsion angle in the first wind blade parameter and the torsion angle in the second wind blade parameter is less than 30 degrees.

[0781] Specifically, in one embodiment, the twist angle of the second blade is preferably 45 degrees, the twist angle of the first blade is smaller than the twist angle of the second blade, and the difference is less than 30 degrees.

[0782] Through the above content, the twist angle affects the amount of introduced fluid, and by limiting the difference between the twist angles of the first blade and the second blade, it is convenient to ensure that the fluid stably enters the volute.

[0783] In another embodiment of the present application, a driving mechanism cover 2 is provided on the wall of the volute opposite to the first fan blade structure 31;

[0784] The driving mechanism cover 2 is connected to the volute through a plurality of connecting arms;

[0785] Gaps are formed between the plurality of connecting arms, and the vent hole is communicated with the outside of the volute through the gaps.

[0786] In one embodiment, a drive mechanism cover 2 is provided on the volute, and the drive mechanism cover 2 includes a plurality of connecting arms, which are connected to the volute by snapping, so that the drive mechanism cover 2 is fixed to the volute. Gaps are formed between adjacent connecting arms, and the gaps are connected to the vent holes of the volute and to the outside of the air duct where the double suction fan 1 is located, so as not to affect the entry of fresh air into the air duct.

[0787] It should be noted that the number and shape of the connecting arms and the connection method with the volute are not specifically limited in this embodiment.

[0788] Through the above steps, the driving mechanism cover 2 is connected to the volute, which makes it easy to install the double-suction fan 1 using the driving mechanism cover 2, so that the double-suction fan 1 is easy to install and has high stability.

[0789] In another embodiment of the present application, a guide ring 21 connected to the volute is provided at the air vent of the volute.

[0790] In one embodiment, the guide ring 21 is annular, and the height of the end surface of the guide ring 21 away from the first fan blade structure 31 is higher than the height of the volute surface. That is, this embodiment does not limit the specific shape of the guide ring 21, and aims to use the guide ring 21 to guide the external air into the volute to form fresh air.

[0791] Through the above steps, the guide ring 21 enables the first fan blade structure 31 to rotate, so that fresh air can be introduced into the interior of the volute, and the amount and efficiency of the introduction of fresh air are improved.

[0792] An embodiment of the present application also provides a clothing processing device, including the drying system described above.

[0793] In one embodiment, the laundry processing device further comprises a controller;

[0794] The controller is configured to:

[0795] Get clothing processing parameters;

[0796] The amount of fluid entering the double suction blower from the vent is changed according to the laundry treatment parameters.

[0797] In one embodiment, the clothing treatment parameter is the clothing treatment stage. Specifically, when the clothing treatment stage is the drying stage, the fluid volume is gradually increased; when the clothing treatment stage is the care stage, the fluid volume is adjusted to the maximum. In another embodiment, the clothing treatment parameter is the temperature of the clothing, and when the temperature exceeds a preset temperature threshold, the fluid volume is increased.

[0798] Specifically, the way to change the fluid volume may be to change the opening of the vent, or to adjust the rotation speed of the double-suction fan, which is not specifically limited in this embodiment.

[0799] Example 3

[0800] like Figure 3a-3e As shown, the fan blade mechanism includes a plurality of fan blades, and a first fan blade partition plate 4 connected to the plurality of fan blades is disposed at the same end of the plurality of fan blades;

[0801] The fan mechanism further includes a second fan partition plate 5, on which a through hole corresponding to the plurality of fan blades is formed; after the plurality of fan blades pass through the through hole, the second fan partition plate 5 divides the plurality of fan blades into a first section 31 and a second section 32; the second fan partition plate 5 can move along the length direction of the fan blades to change the length of the first section 31 and the second section 32;

[0802] In one embodiment, the fan blades of the first section 31 are used to introduce fresh air outside the air duct where the fan is located, and the fan blades of the second section 32 are used to introduce circulating air into the air duct where the fan is located.

[0803] In one embodiment, a plurality of blades are arranged at intervals, and the first blade partition 4 connects the plurality of blades to form a whole. Specifically, the first blade partition 4 can be rotatably connected to each blade so that each blade can rotate and change direction; the first blade partition 4 can also be fixedly connected to each blade to ensure the stability of the blade.

[0804] In one embodiment, the number of the first fan blade partition plate 4 is one, which is connected to the same end of all the fan blades. The same end refers to the end located in the same direction. In another embodiment, the number of the first fan blade partition plates 4 is two, that is, both ends of the fan blade are connected to one first fan blade partition plate 4, which is not specifically limited in this embodiment.

[0805] In one embodiment, the fan uses the fan blade mechanism 3 to introduce and guide the airflow. When the fan is used, the fan needs to be installed in the air duct so that the airflow in the air duct can be encouraged to flow after the fan is started. Since the first section 31 and the second section 32 can guide the airflow at different positions, when the fan is used, the first section 31 of the fan is connected to the outside world outside the air duct where the fan is located, so that the first section 31 of the fan blade can guide the outside airflow outside the air duct where the fan is located into the air duct, thereby increasing the airflow in the air duct.

[0806] It should be noted that the position of the second fan blade partition 5 determines the length of the first section 31 and the second section 32, and when the length of the first section 31 increases, the length of the second section 32 will decrease, and vice versa, when the length of the first section 31 decreases, the length of the second section 32 will increase, because the total length of each fan blade is unchanged. When the length of the first section 31 increases, the amount of fresh air introduced will increase, and when the length of the first section 31 decreases, the amount of fresh air introduced will decrease.

[0807] According to the above content, the fan blade mechanism 3 of the fan is provided with a first section 31 and a second section 32 of variable length, and the first section 31 is used to introduce fresh air outside the air duct where the fan is located, so that when drying clothes, the air volume of the fresh air in the air duct where the fan is located can be increased or reduced by adjusting the position of the second fan blade partition 5. The fresh air flows together with the original circulating air in the air duct where the fan is located, reducing the load of the fan, while helping to increase the wind speed and improve the moisture carrying capacity of the load in the air duct, thereby improving the drying efficiency.

[0808] In another embodiment of the present application, the second air blade partition 5 is magnetic, and the movement of the second air blade partition 5 is controlled by utilizing the magnetism of the second air blade partition 5 .

[0809] In one embodiment, the second fan blade partition 5 is made of magnetic material, so that the second fan blade partition 5 has magnetism. In another embodiment, the second fan blade partition 5 generates magnetism through the principle of electromagnetism.

[0810] When the second fan blade partition 5 has magnetism, the magnetism can be used to control the second fan blade partition 5, so that the second fan blade partition 5 moves along the axial direction of the fan, and the length of the first section 31 and the second section 32 is changed. Specifically, in one application scenario, by installing a power-carrying coil inside or on the top of the fan mechanism, the power-carrying coil can be installed on the volute or the drive mechanism cover so that the power-carrying coil is located at the lower end or upper end of the second fan blade partition. When current is passed through the power-carrying coil, the coil generates suction, driving the second fan blade partition to move upward. If the second fan blade partition needs to move downward, reduce the current so that the gravity of the second fan blade partition is greater than the suction force. In addition, a power-carrying coil can be installed at the lower end and the upper end of the second fan blade partition to control the movement of the second fan blade partition.

[0811] Based on the above content, the magnetism of the second fan blade partition 5 makes it unnecessary to add other driving components in the fan to drive the second fan blade partition 5 to move, thereby reducing the number of parts, saving the space occupied by the fan mechanism 3, and helping to reduce the cost of the fan.

[0812] In another embodiment of the present application, the fan mechanism 3 further includes a driving component, and the driving component is connected to the second fan baffle 5 to drive the second fan baffle 5 to move.

[0813] The driving assembly can be any device or assembly that can drive the second fan blade partition 5 to move, such as an electric cylinder, a pneumatic cylinder, an electric telescopic rod, etc., and this embodiment does not specifically limit this. Since the second fan blade partition needs to rotate with the fan mechanism, the connection between the driving assembly and the second fan blade partition can be achieved by means of a bearing or a flange.

[0814] According to the above content, by setting a driving component in the fan mechanism 3, it is helpful to improve the control accuracy and position stability of the second fan blade partition 5.

[0815] In another embodiment of the present application, the number of the through holes is the same as the number of the plurality of fan blades, and each of the fan blades corresponds to one through hole.

[0816] In one embodiment, one fan blade corresponds to one through hole, that is, the second fan blade partition plate 5 is provided with a plurality of through holes, and the shape, position and number of the through holes correspond to the fan blades one by one. It should be noted that when the fan blades can rotate, the shape and position of the through holes can be determined according to the rotation trajectory and rotation angle of the fan blades, and this embodiment does not specifically limit this.

[0817] According to the above content, compared with opening one through hole for all the fan blades to pass through, opening multiple through holes helps to reduce the opening area of ​​the through holes, thereby improving the strength of the second fan blade partition 5.

[0818] The embodiment of the present application further provides a fan, comprising the above-mentioned fan blade mechanism 3 and a driving mechanism for driving the fan blade mechanism to rotate.

[0819] In another embodiment of the present application, the fan further comprises a volute 1, and the fan mechanism is rotatably disposed in a fan chamber of the volute 1;

[0820] An opening for connecting the fan chamber with the outside of the volute 1 is formed on a wall of the volute 1 opposite to the first section 31 .

[0821] In one embodiment, the volute 1 has a protective effect on the fan blades and a guiding effect on the airflow. The opening on the volute 1 provides conditions for the first section 31 to introduce fresh air, so that the airflow outside the air duct where the fan is located can be introduced into the air duct by the first section 31 through the opening.

[0822] According to the above content, the provision of the volute 1 helps to install and protect the fan mechanism 3, and also helps to control the flow direction of the fresh air.

[0823] In another embodiment of the present application, Figure 3c As shown, a driving mechanism cover 2 is provided on the wall of the volute 1 opposite to the first section 31;

[0824] The driving mechanism cover 2 is connected to the volute 1 through a plurality of connecting arms; gaps are formed between the plurality of connecting arms, and the opening is connected to the outside of the air duct where the fan is located through the gaps.

[0825] In one embodiment, a drive mechanism cover 2 is provided on the volute 1, and the drive mechanism cover 2 includes a plurality of connecting arms. The plurality of connecting arms are connected to the volute 1 by snapping, so that the drive mechanism cover 2 is fixed to the volute 1. Gaps are formed between adjacent connecting arms, and the gaps are connected to the opening of the volute 1 and are also connected to the outside of the air duct where the fan is located, so as not to affect the entry of fresh air into the air duct where the fan is located.

[0826] It should be noted that the present embodiment does not limit the shape and specific structure of the volute 1 and the drive mechanism cover 2.

[0827] Through the above content, the driving mechanism cover 2 is connected to the volute 1, and the fan can be installed using the driving mechanism cover 2, which is convenient, fast and highly stable.

[0828] In another embodiment of the present application, the driving mechanism includes a motor and a power-carrying coil, the output shaft of the motor is connected to the fan blade mechanism for driving the fan blade mechanism to rotate, and the power-carrying coil is located on one side of the second fan blade baffle 32 for driving the second fan blade baffle 32 to move.

[0829] An embodiment of the present application also provides a clothing processing device, comprising the fan described above.

[0830] In one embodiment, the laundry processing device comprises an inner drum and an outer drum;

[0831] The inner drum is rotatably arranged in the outer drum for processing clothes; the outer drum is provided with a loading port;

[0832] A circulating air duct is formed in the clothing processing device, the fan is arranged on the circulating air duct and the first section 31 of the fan is connected to the outside of the circulating air duct, and is used to introduce fresh air from the outside of the circulating air duct; the second section 32 of the fan is located in the circulating air duct, and is used to agitate the airflow in the circulating air duct.

[0833] Specifically, a condensation air duct is provided in the circulation air duct. The hot and humid air flow flowing out of the inner cylinder enters the condensation air duct and is condensed, and condensed water and low-temperature air are separated. Then the low-temperature air passes through the fan, is mixed with the fresh air, and passes through the heater to become high-temperature airflow, and re-enters the inner cylinder.

[0834] In one embodiment, if Figure 3d As shown, the clothing processing device also includes a controller, a mass sensor and a temperature and humidity sensor. Among them, the controller is connected to the mass sensor and the temperature and humidity sensor, and is used to receive signals collected by the mass sensor and the temperature and humidity sensor. Specifically, the mass sensor is installed in the inner drum or between the inner drum and the outer drum, and is used to collect the weight of the load in the inner drum. For example, the weight of the clothes, the mixed weight of the washing water and the clothes, etc.; the temperature and humidity sensor is installed at the air outlet, and is used to collect the temperature and humidity of the airflow at the air outlet. The controller controls the program of the clothing processing device according to the weight, temperature and humidity to wash, dry and care for the clothes.

[0835] The embodiment of the present application further provides a control method, which is applied to the above-mentioned clothes processing device, comprising:

[0836] During the process of drying the clothes, the temperature and / or humidity of the drying air is controlled by changing the length of the first section 31 and the second section 32 of the fan.

[0837] In another embodiment of the present application, the control method further includes:

[0838] S101, obtaining the weight difference between the clothes before and after washing.

[0839] S102, drying the clothes using corresponding drying parameters according to the weight difference.

[0840] In another embodiment of the present application, the controlling the temperature and / or humidity of the drying air by changing the length of the first section and the second section of the fan comprises:

[0841] In the process of drying the clothes by using the corresponding drying parameters according to the weight difference, the lengths of the first section and the second section of the fan are changed according to the temperature and / or humidity of the air outlet.

[0842] In one embodiment, before executing the washing program, the controller obtains the weight of the clothes before washing collected by the mass sensor; after the washing program is completed, the controller obtains the weight of the clothes after washing collected by the mass sensor; and the weight difference is obtained by subtracting the two weights.

[0843] After washing the clothes, enter the drying program. According to the pre-set drying parameter table, the controller searches the drying parameter table corresponding to the weight difference and uses it to dry the clothes. After drying for a period of time, the controller controls the second fan blade baffle 5 to move, increase the length of the first section 31, and reduce the length of the second section 32, so that fresh air enters the circulating air duct. Among them, the time node for controlling the fresh air to enter the circulating air duct can be determined according to the temperature and / or humidity of the air outlet. For example, a temperature threshold and a humidity threshold are preset. When the temperature of the airflow at the air outlet reaches the temperature threshold and the humidity reaches the humidity threshold, the fresh air is controlled to enter. The amount of fresh air entering can be preset, that is, the amount of fresh air entering is different at different positions of the second fan blade baffle 5. It can be set according to actual conditions, and this embodiment does not make specific limitations on this.

[0844] In another embodiment of the present application, after changing the lengths of the first section 31 and the second section 32 in the fan according to the temperature and / or humidity of the air outlet, the method further includes:

[0845] When the weight of the clothes reaches a preset weight threshold, the length of the first section 31 is increased and the length of the second section 32 is shortened.

[0846] Specifically, for ease of understanding, a washing machine with washing, drying and care functions is taken as an example for explanation.

[0847] After the weight difference is calculated, the double suction fan is started. The double suction fan refers to a fan that can introduce fresh air.

[0848] The initial drying time T of the fan is set, and the first drying program is executed. The first drying program and T are both determined according to the weight difference. Specifically, the drying parameters in the first drying program are retrieved from a preset drying parameter table according to the weight difference.

[0849] Determine whether the weight of the clothes in the washing chamber has reached the set weight.

[0850] If the set weight is reached, the second drying process is performed.

[0851] If the set weight is not reached, a matching drying program is executed according to other washing information, and then a second drying program is executed.

[0852] The difference between the second drying program and the first drying program at least includes increasing the fresh air volume, that is, increasing the length of the first section 31. Other parameters may be different or not, and this embodiment does not specifically limit this.

[0853] Among them, executing the matching drying program according to other washing information means that the drying program has not been completed or the drying program of the clothes has not reached the preset standard, so the weight of the clothes has not reached the set weight. At this time, the drying time can be extended, or the power of the heater can be increased according to the washing information such as the weight of the clothes / humidity of the air outlet to increase the air flow temperature. This embodiment does not limit the specific control process, and is intended to complete the drying of the clothes by executing the matching drying program.

[0854] After executing the second air-drying procedure, it is determined whether the humidity in the washing chamber reaches the set temperature, that is, the humidity at the air outlet is collected.

[0855] If the set temperature is not reached, the third sealing process is performed.

[0856] If the set temperature is reached, the fan is turned off and the drying ends.

[0857] Among them, the set temperature is not reached, which proves that the care of the clothes is not completed. The third air-drying program executed at this time is intended to care for the clothes. Therefore, compared with the second air-drying program, the length of the first section 31 is increased to further increase the amount of fresh air, thereby avoiding high air flow temperature in the circulating air duct and damaging the clothes.

[0858] Example 4

[0859] According to an embodiment of the present application, a laundry processing device embodiment is provided, such as Figure 4a-4e As shown, the clothes processing equipment includes a clothes processing barrel, a main drying air duct, a ventilation pipe air duct and a connecting air duct;

[0860] The clothes treatment barrel comprises an inner drum 3 and an outer drum 2 and an air inlet for taking air into the inner drum 3, the outer drum 2 is provided with a first air outlet, the main drying air duct is connected between the air inlet and the first air outlet, and the main drying air duct, the outer drum 2 and the inner drum 3 form a drying air path that can provide a drying airflow circulation flow;

[0861] The main drying air duct includes a first condensing air duct 4 arranged at the rear of the outer cylinder;

[0862] One end of the ventilation pipe duct 8 is connected to the outer drum 2 of the clothing processing device and communicates with the outer drum 2 of the clothing processing device, and the other end forms a port that communicates with the external air of the clothing processing device;

[0863] The first end of the connecting air duct 10 is in communication with the ventilation pipe air duct 8, and the second end of the connecting air duct 10 is in communication with the first condensation air duct 4 of the clothes processing device, so that the gas in the ventilation pipe air duct 8 can enter the first condensation air duct 4 through the connecting air duct 10;

[0864] A cooler is installed on the air duct 8, and the cooler is used to cool the gas in the air duct 8;

[0865] The connecting air duct 10 is provided with a second fan 11 to provide power for the gas in the connecting air duct 10 to flow toward the first condensing air duct 4;

[0866] The main drying air duct is provided with a first fan 6 to provide power for the drying air flow to flow in the drying air duct.

[0867] In one embodiment, the air inlet may be disposed at the door seal of the clothing processing device, or may be disposed on the inner drum 3, which is not specifically limited in this embodiment.

[0868] For ease of understanding, in order to balance the internal air pressure, the clothes processing device will be provided with an exhaust device for discharging the internal gas to the outside, so that when the clothes processing device is drying the clothes, the internal gas of the clothes processing device will also be frequently discharged to the outside through the exhaust device, thereby reducing the total amount of gas used to dry the clothes in the clothes processing device. In addition, even if the total amount of internal gas is constant, as the drying time increases, the gas in the clothes processing device is prone to produce odor, thereby affecting the odor of the clothes and reducing the drying effect of the clothes.

[0869] In order to improve the drying efficiency and drying effect, in one embodiment, a connecting air duct 10 is provided, wherein the first end of the connecting air duct 10 is connected to the ventilation duct 8. The ventilation duct 8 is an original exhaust structure of the clothes processing device, and is provided between the outer drum 2 and the fresh air outlet 12, wherein the fresh air outlet 12 is an outlet connecting the inside of the clothes processing device with the outside.

[0870] The second end of the connecting air duct 10 is connected to the first condensing air duct 4 of the clothes processing device. The first condensing air duct 4 is a passage for condensing hot and humid gas when the clothes processing device dries clothes, and is usually opened inside the clothes processing device.

[0871] Specifically, the communication position between the connecting air duct 10 and the ventilation pipe duct 8 is located between the cooler and the port where the ventilation pipe duct 8 communicates with the external air.

[0872] In one embodiment, if Figure 4b As shown, since the first end of the connecting air duct 10 is connected to the ventilation pipe duct 8, and the ventilation pipe duct 8 is connected to the fresh air outlet 12 of the clothes processing device, three vents are formed at the first end of the connecting air duct 10. Among them, the first vent is the fresh air outlet 12, and after the gas enters the first vent, it is discharged from the fresh air outlet 12 to the outside of the clothes processing device; the second vent is the first end of the connecting air duct 10, and after the gas enters the second vent, it enters the connecting air duct 10; the third vent is the ventilation pipe duct 8, and the gas usually moves from the third vent to the third vent.

[0873] A cooler is installed on the ventilation duct 8, so that the gas in the ventilation duct 8 is cooled by the cooler before reaching the three ventilation ports, and changes from humid hot gas to low temperature gas. If the low temperature gas is discharged to the outside from the fresh air outlet 12, it helps to reduce the pollution of the outside air, protect the environment, and reduce the emission of humid hot gas. If the low temperature gas is discharged from the connecting air duct 10 to the first condensation duct 4, the total amount of air in the first condensation duct 4 is increased, and it is not easy to affect the temperature of the original gas in the first condensation duct 4, which is convenient for drying clothes without affecting the drying effect.

[0874] In one embodiment, a second fan 11 is installed on the connecting air duct 10, so that when fresh air needs to be introduced into the first condensation air duct 4, the second fan 11 is turned on to increase the total amount of gas entering the connecting air duct 10, thereby increasing the total amount of gas entering the first condensation air duct 4, so that the total amount of gas used to dry clothes is sufficient, thereby improving the drying efficiency.

[0875] According to the above content, during the process of exhausting gas from the clothing processing equipment, a part of the exhausted gas will enter the connecting air duct 10, and then enter the first condensation air duct 4 of the clothing processing equipment through the connecting air duct 10, so that the gas in the first condensation air duct 4 can be replenished, so that the amount of gas is sufficient for clothing processing, thereby improving the drying efficiency when drying clothes.

[0876] In another embodiment of the present application, Figure 4c As shown, the cooler forms a cooling tower water box structure, which includes a box body, one side of the box body is provided with an air inlet 9.1, and the other side opposite to the position of the air inlet 9.1 is provided with an exhaust port 9.4; a condensate inlet pipe 9.2 is installed in the box body, and at least one water outlet 9.2.1 is provided on the condensate inlet pipe 9.2; at least one drain pipe is installed in the box body, and a drain pipe is provided with a drain port 9.3 opposite to the water outlet 9.2.1.

[0877] It should be noted that the cooling tower water box structure, i.e., the cooling tower water box 9, refers to a device that uses the water cooling principle to cool down the gas in the air duct 8. In this embodiment, the cooling tower water box 9 is preferred to help improve the cooling efficiency.

[0878] For ease of understanding, Figure 4c For example, the condensate inlet pipe 9.2 is located above the box body, and the outlet 9.2.1 is opened toward the bottom of the box body. All drain pipes are located below the condensate inlet pipe 9.2, so that after the outlet 9.2.1 discharges water, they receive the water discharged by the outlet 9.2.1. The drain outlet 9.3 on the drain pipe is opposite to the outlet 9.2.1, so that the water received by the drain pipe can be discharged. The gas in the air duct 8 passes through the box body, contacts the water flow, and exchanges heat, so that the temperature of the gas is reduced.

[0879] Through the above content, the cooling tower water box 9 has a simple structure, is easy to install, has high cooling efficiency, and is easy to ensure that the temperature of the gas discharged to the outside or returned to the cooling pipe is low. It is environmentally friendly and helps to improve the drying efficiency.

[0880] In another embodiment of the present application, the connecting air duct 10 is provided with a first control valve, and the ventilation pipe air duct 8 is provided with a second control valve.

[0881] In one embodiment, the first control valve has the function of blocking the connecting air duct 10. The specific structure of the first control valve is not limited in this embodiment, as long as the first control valve is in a closed state, the connecting air duct 10 can be blocked. Blocking the connecting air duct 10 means that the gas in the air duct 8 or the outside world cannot enter the first condensing air duct 4 from the connecting air duct 10.

[0882] Similarly, the second control valve can block the air duct of the ventilation pipe when closed.

[0883] Through the above content, when the first control valve is closed, it can block the connecting air duct 10, so that when the clothing processing equipment needs to discharge gas to the outside, the discharged gas will not re-enter the clothing processing equipment from the connecting air duct 10, thereby ensuring the efficiency of the clothing processing equipment in discharging gas to the outside.

[0884] In another embodiment of the present application, along the flow direction of the drying airflow of the main drying air duct, the connecting position of the connecting air duct 10 and the first condensing air duct 4 is downstream of the connecting position of the first air outlet of the outer cylinder 2 and the connecting air duct 10.

[0885] The first condensation air duct 4 has a certain length, and the first condensation air duct 4 is divided into two parts according to the length of the first condensation air duct 4, and then the first condensation air duct 4 can be divided into an upstream part and a downstream part according to the flow direction of the gas in the first condensation air duct 4. Specifically, the gas in the first condensation air duct 4 first passes through the upstream part and then passes through the downstream part.

[0886] Through the above content, the second end of the connecting air duct 10 is located downstream of the first condensation air duct 4, so that after the gas in the connecting air duct 10 enters the first condensation air duct 4, it is not easy to affect the condensation effect of the original gas in the first condensation air duct 4, thereby ensuring the condensation effect of the gas in the clothing processing equipment, thereby ensuring the drying effect.

[0887] For ease of understanding, Figure 4d As shown, in the washing stage or the early stage of the drying stage of the clothes processing device, the gas in the inner drum 3 will circulate inside the clothes processing device through the first condensation duct 4. At the same time, part of the gas in the clothes processing device will be discharged to the outside through the outer drum 2 and the ventilation duct 8 to balance the air pressure inside the clothes processing device. At this time, the second fan 11 is in a closed state, so that the connecting duct 10 is blocked, and the gas cannot enter the first condensation duct 4 from the connecting duct 10. At the same time, the gas in the ventilation duct 8 will be cooled through the cooling tower water box 9 and then reach the outside.

[0888] like Figure 4e As shown, in the drying stage or the late stage of the drying stage of the clothes processing device, the second fan 11 is controlled to be turned on, so that the connecting air duct 10 is connected. The gas passing through the cooling tower water box 9 is reintroduced into the connecting air duct 10 by the second fan 11, enters the cooling air duct, and participates in the subsequent drying, so that the total amount of gas used to dry the clothes is increased, and the drying efficiency is improved.

[0889] In another embodiment of the present application, the main drying air duct further includes a heating air duct, and the clothing processing equipment further includes a heating device, which is arranged on the heating air duct and is used to heat the drying gas condensed by the first condensation air duct 4.

[0890] In another embodiment of the present application, the first fan 6 is a double-suction fan, and the first fan 6 includes a first air inlet connected to the outside of the clothing processing device and a second air inlet connected to the first condensation air duct 4.

[0891] In another embodiment of the present application, a second air outlet is further provided at the rear of the outer cylinder 2, which is arranged above the first air outlet at the height of the outer cylinder, and the clothing processing device is further provided with a second condensation air duct 7, the first condensation air duct 4 is connected to the first air outlet at a lower position, the second condensation air duct 7 is connected to the second air outlet at a higher position, the other end of the second condensation air duct 7 is connected to the first condensation air duct 4, and the connecting position of the connecting air duct and the first condensation air duct 4 is located downstream of the connecting position of the second condensation air duct and the first condensation air duct 4.

[0892] The present application also provides a clothing processing device, such as Figure 4b As shown, it includes a clothes processing barrel, a main drying air duct, a ventilation pipe air duct 8 and a connecting air duct 10; the clothes processing barrel includes an inner barrel 3 and an outer barrel 2 and an air inlet for air intake to the inner barrel 3, and the outer barrel 2 is provided with a first air outlet and a second air outlet;

[0893] The main drying air duct is connected between the air inlet and the first air outlet, and the main drying air duct, the outer drum 3 and the inner drum 2 form a drying air path that can provide a drying airflow circulation flow;

[0894] The main drying air duct includes a first condensation air duct 4 and a second condensation air duct 7;

[0895] The first condensation air duct 4 is connected to the first air outlet at a lower position, one end of the second condensation air duct 7 is connected to the second air outlet at a higher position, and the other end is connected to the first condensation air duct 4, and the connecting position of the connecting air duct 10 and the first condensation air duct 4 is located downstream of the connecting position of the second condensation air duct 7 and the first condensation air duct 4;

[0896] One end of the ventilation pipe duct 8 is connected to the outer drum 2 of the clothing processing device and communicates with the outer drum 2 of the clothing processing device, and the other end is communicated with the external air of the clothing processing device; a cooler is installed on the ventilation pipe duct 8, and the cooler is used to cool the gas in the ventilation pipe duct 8;

[0897] The first end of the connecting air duct 10 is in communication with the ventilation pipe air duct 8, and the second end of the connecting air duct 10 is in communication with the first condensation air duct 4 of the clothes processing device, so that the gas in the ventilation pipe air duct 8 can enter the first condensation air duct 4 through the connecting air duct 10;

[0898] The clothes processing device further includes a heating device, and the main drying air duct further includes a heating air duct, and the heating device is arranged on the heating air duct to heat the drying gas condensed by the first condensation air duct 4;

[0899] The clothes processing device further comprises a first fan 6, which is located on the main drying air duct and provides power for the drying air flow to flow in the drying air duct; the first fan 6 is a double-suction fan, which comprises a first air inlet connected to the outside of the clothes processing device and a second air inlet connected to the first condensing air duct 4;

[0900] The connecting air duct 10 is provided with a second fan 11 to provide power for the gas in the connecting air duct to flow toward the first condensing air duct 4 .

[0901] In one embodiment, a first control valve is provided on the connecting air duct 10 , and a second control valve is provided on the ventilation pipe air duct 8 .

[0902] The embodiment of the present application further provides a control method for a clothes processing device, wherein the clothes processing device is the clothes processing device described above, and the control method comprises:

[0903] Obtaining a processing stage of a laundry processing device;

[0904] When the processing stage is the washing water inlet stage, the first fan is turned on and the second fan is turned off, so that the drying airflow inside the clothes processing drum is directly discharged from the air duct of the ventilation pipe to the outside of the clothes processing drum;

[0905] When the processing stage is the drying stage, turn on the first fan and the second fan to make a part of the drying airflow circulate between the inner cylinder, the outer cylinder and the main drying air duct and the inner cylinder, and a part of the drying airflow circulates between the inner cylinder, the outer cylinder, the ventilation pipe air duct, the connecting air duct, the main drying air duct and the inner cylinder.

[0906] Specifically, obtaining a processing stage of a clothes processing device;

[0907] When the treatment stage is the washing water inlet stage, the second fan 11 is controlled to be closed to block the connecting air duct 10, and the gas inside the box 1 is discharged to the outside through the air duct 8;

[0908] When the processing stage is the drying stage, the second fan 11 is controlled to be turned on, and the gas entering the ventilation duct 8 is cooled by the cooling tower water box 9 and then sucked into the connecting duct 10 by the second fan 11, re-enters the first condensation duct, is heated by the heating device 5, and then enters the inner drum 3 to dry the clothes.

[0909] Example 5

[0910] like Figure 5a to Figure 5e As shown, the clothing processing device may be a washing and drying machine with a drying function, or a drying machine, etc.

[0911] On the one hand, the clothing processing device in the prior art first sucks external air into the air duct, then heats the sucked air through a heater, and then introduces it into the drying drum. Under the action of the hot air, the water on the clothes evaporates and forms humid hot air with the air, and then the humid hot air is discharged from the exhaust duct in the exhaust structure to achieve the purpose of drying the clothes. However, in actual use, if the temperature of the discharged humid hot air is higher than that of the external air and the temperature difference with the external air is large, it is easy to generate a large amount of water vapor. A large amount of water vapor gathers and rises, that is, steam occurs, which affects the customer's usage experience.

[0912] Based on this, a drying control method of a clothes processing device according to an embodiment of the present invention includes:

[0913] In the preset mode of the drying system, the ambient air parameters outside the laundry treatment tub 9 and the uncooled drying air flow parameters inside the drying system are obtained;

[0914] The external ambient air parameters of the laundry treatment tub 9 and the uncooled drying airflow parameters inside the drying system are compared, and the discharge speed and / or discharge rhythm of the drying airflow discharged from the discharge port to the outside of the laundry treatment tub 9 are controlled according to the comparison result.

[0915] Specifically, the ambient air parameters may be the air parameters surrounding the clothing processing barrel 9, the air parameters may be temperature and humidity, etc., the drying airflow parameters may be the temperature and humidity of the drying airflow, etc. By comparing the ambient air parameters and the drying airflow parameters, it can be determined whether a large amount of condensation will be formed when the drying airflow contacts the ambient air after being discharged from the clothing processing device, and then the temperature and humidity of the drying airflow in contact with the ambient air after being discharged from the drying system can be adjusted by controlling the discharge speed and / or discharge rhythm of the drying airflow. Condensation can be reduced or eliminated by lowering the temperature and / or humidity of the drying airflow.

[0916] Among them, the drying airflow channel 7 has a certain length, and the drying airflow can be cooled in the drying airflow channel, and then the temperature of the drying airflow will be reduced when it reaches the exhaust structure 6. The length of the drying airflow channel 7 can be determined according to the test. By changing the discharge speed and / or discharge rhythm of the drying airflow, the time of the drying airflow in the drying airflow channel can be increased or slowed down, thereby adjusting the temperature of the drying airflow when it is discharged.

[0917] In some embodiments, the exhaust structure 6 is disposed on the outer drum 11 of the laundry treatment drum or on the cooling section inlet side of the outer drying air flow channel 7;

[0918] The external ambient air parameters of the laundry treatment barrel 9 are the ambient air parameters outside the exhaust structure 6;

[0919] The parameters of the uncooled drying air flow inside the drying system are the parameters of the drying air flow inside the exhaust structure 6 .

[0920] Specifically, the exhaust structure 6 is the last component that the drying airflow passes through before being discharged from the clothing processing barrel 9. The air in the external environment where the exhaust structure 6 is located is the external environment air of the clothing processing barrel, and the drying airflow inside the exhaust structure 6 is the uncooled drying airflow inside the drying system.

[0921] In some embodiments, the external ambient air parameter includes external ambient air temperature;

[0922] The drying air flow parameters include drying air flow temperature;

[0923] The step of controlling the discharge speed and / or the discharge rhythm of the drying airflow discharged to the outside of the laundry treatment tub 9 through the discharge port according to the comparison result includes:

[0924] If the external ambient air temperature T2 is lower than or equal to the drying airflow T1, and ΔT=T1-T2≧ΔT 1设 When the discharge speed is reduced and / or the discharge rhythm is slowed down.

[0925] When comparing the drying airflow parameters and the ambient air parameters, the temperatures of the two can be compared. Since the drying airflow itself is a humid and hot gas and carries a large amount of water vapor, when the temperature difference between the two, that is, ΔT, is higher than a certain value, a large amount of condensation will be produced when the drying airflow meets the ambient air, affecting the user experience. At this time, the discharge speed of the drying airflow can be reduced, or the discharge rhythm can be slowed down so that the drying airflow can stay in the drying system longer and be fully condensed. By lowering the temperature to a certain extent, ΔT can be reduced, so that the drying airflow can reduce or no condensation when it comes into contact with the ambient air.

[0926] In some embodiments, during the drying process, if the external temperature T2 of the exhaust structure 6 is higher than the internal temperature T1 of the exhaust structure 6 or the external temperature T2 of the exhaust structure 6 is lower than the internal temperature T1 of the exhaust structure 6, but ΔT=T1-T2<ΔT 1设 , the discharge speed is controlled to increase and / or the discharge rhythm becomes faster.

[0927] Specifically, if the value of ΔT is less than a certain value ΔT 1设 , ΔT 1设 It can be obtained through calculation or set by the user according to usage. The temperature difference between the drying airflow and the ambient air is small, which can be 20°C. At this time, condensation is not easy to occur. The discharge speed and / or discharge rhythm can be appropriately increased to speed up the flow of the drying airflow and improve the drying efficiency.

[0928] In some embodiments, the external ambient air parameter includes external ambient air humidity;

[0929] The drying air flow parameters include drying air flow humidity;

[0930] The control of the discharge speed and / or the discharge rhythm of the drying airflow discharged to the outside of the laundry treatment tub 9 through the discharge port according to the comparison result includes:

[0931] If the humidity of the external ambient air d2 is greater than or equal to the humidity of the drying air d1, and Δd=d2-d1≧Δd 1设 When the discharge speed is reduced and / or the discharge rhythm is slowed down.

[0932] The drying airflow parameter and the external environment parameter can also be humidity. When Δd is greater than a preset parameter Δd 1设 When the drying air is in the drying system, a large amount of condensation is likely to occur. At this time, the exhaust speed and / or exhaust rhythm of the drying airflow can be controlled to increase the time the drying airflow stays in the drying system so that the drying airflow can be fully condensed. 1设 It can be obtained through calculation or set by the user according to usage conditions, and the relative humidity can be 30%.

[0933] In some embodiments, the external ambient air parameters further include external ambient air temperature and;

[0934] The drying air flow parameters also include drying air flow temperature;

[0935] The control of the discharge speed and / or the discharge rhythm of the drying airflow discharged to the outside of the laundry treatment tub 9 through the discharge port according to the comparison result includes:

[0936] If the humidity d2 of the external ambient air is less than the humidity d1 of the drying airflow, compare the temperature T2 of the external ambient air with the temperature T1 of the drying airflow;

[0937] If the external ambient air temperature T2 is lower than or equal to the drying air flow temperature T1, and also lower than or equal to the dew point temperature Tb of the drying air flow, the discharge speed is reduced and / or the discharge rhythm is slowed down.

[0938] Specifically, factors that affect the condensation phenomenon also include the dew point temperature Tb. When the external ambient air temperature T2 is lower than or equal to the drying airflow temperature T1, and lower than or equal to the dew point temperature Tb of the drying airflow, it can also be judged that a large amount of condensation will be generated when the drying airflow contacts the ambient air. At this time, the discharge speed is reduced and / or the discharge rhythm is slowed down to allow the drying airflow to be fully condensed and cooled in the drying system before being discharged.

[0939] In some embodiments, if the external ambient air temperature T2 is greater than or equal to the drying air flow temperature T1 and greater than the dew point temperature Tb of the drying air flow, the discharge speed is increased and / or the discharge rhythm is accelerated.

[0940] Factors that affect the condensation phenomenon also include the dew point temperature Tb. When the external ambient air temperature T2 is greater than or equal to the drying airflow temperature T1, and greater than the dew point temperature Tb of the drying airflow, it can also be judged that the contact between the drying airflow and the ambient air will not produce a large amount of condensation. At this time, the drying airflow is fully condensed and cooled in the drying system before being discharged by reducing the discharge speed and / or slowing down the discharge rhythm.

[0941] According to the drying control method of the clothing processing device of an embodiment of the present invention, in the preset mode of the drying system, the ambient air parameters outside the clothing processing barrel 9 and the uncooled drying airflow parameters inside the drying system are obtained and compared to determine whether a large amount of condensation will be generated when the drying airflow is discharged to the outside and contacts with the ambient air, and then the discharge speed and / or discharge rhythm of the drying airflow are adjusted according to the comparison result, so that the drying airflow can be fully condensed and cooled in the drying system before being discharged. This can avoid that after the drying airflow is discharged from the drum, a large amount of condensation will be generated when it encounters ambient air with a large temperature difference due to its high temperature and high humidity, thereby affecting the customer's usage experience.

[0942] Among them, when the moisture content in the air exceeds the saturation concentration, water will condense out, and the higher the temperature, the more moisture the air can contain; conversely, the lower the temperature, the less moisture the air can contain; after judging that a large amount of water vapor will be generated when the dry air flow is discharged from the drum, and after forming a steam phenomenon, the discharge speed of the dry air flow is immediately reduced. Specifically, a regulating valve can be set in the discharge channel of the dry air flow, and the discharge speed of the dry air flow can be adjusted by the regulating valve. An exhaust fan 3 can also be set, and the exhaust speed of the dry air flow can be adjusted by adjusting the rotation speed of the exhaust fan 3. When it is necessary to reduce the discharge speed of the dry air flow, the rotation speed of the exhaust fan 3 can be reduced, so that the dry air flow stays in the air duct inside the drum for a longer time, so that the dry air flow can be cooled more in the air duct and condensed more fully. Before the dry air flow is discharged from the drum, the temperature of the dry air flow is reduced to reduce the water vapor in the dry air flow, so as to avoid the dry air flow encountering cold air after being discharged from the drum to generate a large amount of water vapor, generate steam phenomenon, and affect the customer's use experience.

[0943] The present application also proposes a clothing processing device, which can achieve the technical effect of reducing condensation and avoiding affecting customer experience through the above-mentioned control method.

[0944] The present application further proposes a clothing processing device, comprising: the clothing processing device is provided with a drying system, the drying system comprises a clothing processing barrel 9, the clothing processing barrel 9 comprises an inner barrel 10 and an outer barrel 11, the inner barrel 10 is provided with an air inlet 101, the outer barrel 11 is provided with an air outlet 111, the drying system comprises an external drying air flow channel 7 connected between the air inlet 101 and the air outlet 111, the external drying air flow channel 7 is provided with an exhaust structure 6, the exhaust structure 6 is provided with a discharge port connected to the external air of the clothing processing barrel 9 and an exhaust fan 3 providing exhaust power for the drying air flow, the discharge port discharges the drying air flow of the drying system to the outside of the clothing processing barrel 9 in a preset drying mode of the drying system;

[0945] The control unit includes a controller, a first detection module 4 and a second detection module 5, wherein the first detection module 4 is used to detect the drying airflow parameters inside the exhaust structure 6, and the second detection module 5 is used to detect the ambient air parameters outside the exhaust structure 6; the controller controls the exhaust speed and / or exhaust rhythm of the exhaust fan 3 based on the drying airflow parameters fed back by the first detection module 4 and the ambient air parameters fed back by the second detection module 5.

[0946] Specifically, the air inlet 101 of the inner drum 10 can be directly realized at the tube mouth of the inner drum 10, and the drying system supplies air to the tube mouth of the inner drum 10 through the door seal of the laundry processing device, and sends the drying airflow into the drum. The first detection module 4 and the second detection module 5 can be temperature and humidity detection sensors, respectively, which can detect the temperature and humidity of the drying airflow and the ambient air, respectively, and feed back the signal to the controller. The controller can control the exhaust fan 3 according to the feedback signal, and adjust the exhaust wind speed and / or exhaust rhythm of the exhaust fan 3 to adjust the discharge speed of the drying airflow, thereby adjusting the residence time of the drying airflow in the drying system, and adjusting the condensation and cooling degree of the drying airflow, so that the drying airflow will not produce a large amount of condensation when it contacts the ambient air after being discharged, thereby affecting the user experience. Under this premise, the flow rate of the drying airflow can also be made as fast as possible to improve the drying efficiency.

[0947] In some embodiments, the discharge structure includes an air inlet channel 1 and an air vent 2, one end of the air inlet channel 1 is connected to the outer drum 11 of the laundry treatment drum or the outer drying air flow channel 7, and the other end of the air inlet channel 1 is connected to the air vent 2; the other end of the air vent 2 is the discharge port;

[0948] The flow area of ​​the air vent 2 is larger than the flow area of ​​the air inlet passage 1 , and the exhaust fan 3 is arranged on the air inlet passage 1 .

[0949] Specifically, the flow area of ​​the air holes 2 is larger than the flow area of ​​the air inlet channel 1, which can prevent a large amount of drying airflow from being retained in the discharge structure and affecting the normal exhaust function of the discharge structure.

[0950] In some embodiments, the first detection module 4 is disposed outside the discharge structure, and the second detection module 5 is disposed inside the air vent 2 .

[0951] The first detection module 4 and the second detection module 5 are specifically arranged outside the discharge structure and inside the air vent 2, and can detect the air parameters of the area closest to the contact between the drying airflow and the ambient air, so that the parameter comparison result obtained by the controller is more accurate.

[0952] In some embodiments, it also includes: a fresh air intake channel 1 and an air volume regulating unit 8 arranged on the fresh air intake channel 1, wherein the air volume regulating unit 8 is electrically connected to the controller, and the air volume regulating unit 8 is used to control the fresh air volume introduced by the fresh air intake channel 1.

[0953] Specifically, the air duct control device can be adjusted through the controller. When the exhaust speed of the drying airflow is faster, the controller can control the air duct control device to increase the air volume entering the drying air duct at the same time, that is, to increase the air inlet speed of the drying air duct at the same time. When the exhaust speed of the drying airflow is slower, the controller can control the air duct control device to reduce the air volume entering the drying air duct 7 at the same time, that is, to reduce the air inlet speed of the drying air duct at the same time. The air volume of the drying system can be maintained at a balanced total amount, avoiding the generation of negative pressure or high pressure in the drying air duct, affecting the normal flow of the drying airflow, and even affecting the service life of the drying air duct.

[0954] In some embodiments, the clothing processing device is provided with a drying system, the drying system comprising a clothing processing barrel 9, the clothing processing barrel 9 comprising an inner barrel 10 and an outer barrel 11, the inner barrel 10 being provided with an air inlet 101, the outer barrel 11 being provided with an air outlet 111, the drying system comprising an external drying air flow channel 7 connected between the air inlet 101 and the air outlet 111, the external drying air flow channel 7 being provided with an exhaust structure 6, a plurality of guide ducts of different lengths and / or inner diameters being selectively connected between the external drying air flow channel 7 and the exhaust structure 6, the exhaust structure 6 being provided with an exhaust port connected to the external air of the clothing processing barrel 9, the exhaust port exhausting the drying air flow of the drying system to the outside of the clothing processing barrel 9 under a preset drying mode of the drying system.

[0955] Specifically, a plurality of guide pipes of different lengths and / or different inner diameters may be provided between the external drying airflow channel 7 and the exhaust structure 6, and the exhaust speed of the drying airflow may be changed by selecting different pipes for exhaust.

[0956] A control valve is arranged in each of the diversion pipes.

[0957] The control valve can be a solenoid valve. Each flow guide pipe is controlled to open and close by a solenoid valve. When ΔT is reached, 1设 When the electromagnetic valve of the diversion pipe with a longer length or a larger inner diameter is controlled to open, the electromagnetic valves of the other diversion pipes are closed; conversely, the electromagnetic valve of the pipe with a shorter length and a smaller inner diameter is opened, and the electromagnetic valve of the long pipe is closed.

[0958] Example 6

[0959] like Figure 6a to Figure 6b As shown, the clothing processing device can be a dryer or a washing machine with a drying function. With the improvement of people's living standards, clothing processing devices have long become one of the indispensable household appliances in daily life. The existing clothing processing devices have two condensation systems. One is to connect the condensation duct to the inner drum so that the hot and humid gas in the inner drum is combined with the condensed water in the condensation duct to form dry air. The other is to set a condensation structure in the outer drum. The condensation structure is composed of one guide rib or multiple guide ribs. After the hot and humid air enters the outer drum, the hot and humid air is combined with the condensed water flowing on the condensation structure to form dry air.

[0960] On the one hand, although the hot and humid air is continuously condensed during the clothes drying process, some hot and humid gases will still be discharged from the air vents. When this part of the hot and humid gases comes into contact with the cooler air outside, it is easy to form a large amount of water vapor, affecting the customer's experience.

[0961] Based on this, as shown in FIG1 , a clothes processing device according to an embodiment of the present invention comprises: a clothes processing drum, the clothes processing drum comprising an outer drum 1 and an inner drum pivotably arranged in the outer drum 1, an inner drum air duct is formed between the outer drum 1 and the inner drum, and the inner drum air duct is used to circulate drying air;

[0962] A water inlet pipe 2, the water inlet pipe 2 is used to be connected to a water source in a switchable manner;

[0963] an exhaust pipe 3, the exhaust pipe 3 being used to communicate with the external atmosphere; and

[0964] The air pipe 4 has a smaller diameter than the exhaust pipe 3, the bottom end of the air pipe 4 is connected to the air duct in the cylinder and is located in the top area of ​​the outer cylinder 1, the top end of the air pipe 4 is connected to the water inlet pipe 2 and the exhaust pipe 3 respectively, and the top end of the air pipe 4 is lower than the air outlet of the exhaust pipe 3.

[0965] Specifically, the clothing processing drum of the clothing processing device includes an inner drum and an outer drum 1, the air vent 4 is connected to the top area of ​​the outer drum 1, and the air vent is connected to the air duct in the drum. When the drying air circulates in the air duct in the drum, the air vent can effectively discharge the gas in the clothing processing drum and stabilize the air pressure in the clothing processing drum. A three-way pipe can be set at the top of the air vent 4, and the top of the air vent 4 can be connected to the water inlet pipe 2 and the exhaust pipe 3 respectively through the three-way pipe. Moreover, the top of the air vent 4, that is, the highest point of the air vent 4, is lower than the air outlet of the exhaust pipe 3, so that the entire tube body of the exhaust pipe 3 is higher than the air vent 4, so that the condensate discharged from the water inlet pipe 2 can enter the air vent 4 under the action of gravity, thereby preventing the condensate from entering the exhaust pipe 3 and affecting the exhaust of the exhaust pipe 3. The diameter of the air vent 4 is smaller than that of the exhaust pipe 3, which can ensure that all the gas in the air vent 4 can be discharged from the exhaust pipe 3 smoothly. The clothes in the clothing treatment drum can go from the air vent 4 to the exhaust pipe 3 and finally be discharged to the external atmosphere. The water inlet pipe 2 is connected to the top of the air vent 4. When necessary, condensed water can be discharged to the inside of the air vent 4 through the water inlet pipe 2. The volume of the condensed water does not need to be too much, and the air vent 4 will not be blocked. The air in the air vent 4 can flow upward and contact with the condensed water before entering the exhaust pipe 3 to form dry air. This can prevent gases with excessive temperature and humidity from being directly discharged to the outside, and prevent the gases discharged from the clothing treatment device from contacting with the cold air outside to form a large amount of water vapor, affecting the customer's usage experience.

[0966] Among them, the top area is the area close to the top of the outer tube 1, which can be the upper half of the outer tube 1. After the air tube 4 is connected to this area, the condensed water at the top of the air tube 4 can flow downward, and the air at the bottom of the air tube 4 can be discharged upward, so that the air contacts the condensed water. Preferably, the air tube 4 can be connected to the top of the outer tube 1.

[0967] According to the clothing processing device of the embodiment of the present invention, the top of the air pipe 4 is connected to the water inlet pipe 2 and the exhaust pipe 3 respectively. When the temperature of the gas in the air pipe 4 is high or the humidity is high, condensation water can be injected into the air pipe 4 through the water inlet pipe 2, so that the gas in the air pipe 4 can be condensed by the condensation water while being discharged through the exhaust pipe 3, so that the temperature and humidity of the gas discharged from the air pipe 4 can be controlled, and it is avoided that the gas with high temperature and high humidity is directly discharged from the air pipe 4 to form a large amount of water vapor, which affects the customer's usage experience.

[0968] In some embodiments, it further includes: a detergent box 5, the detergent box 5 is located above the outer tub 1;

[0969] The end of the water inlet pipe 2 facing away from the ventilation pipe 4 is communicated with the water inlet of the detergent box 5 .

[0970] Specifically, the water inlet pipe 2 is connected to an external water source, and the external water source may be an external water pipeline, that is, in addition to the water pipeline of the original clothing processing device, an additional water inlet pipeline is provided to communicate with the water inlet pipe 2 .

[0971] Furthermore, the water inlet pipe 2 can also be connected to the water inlet of the detergent box 5 of the clothing processing device. First, the air vent 4 is close to the detergent box 5, and there is no need to make large-scale changes to the internal pipes of the clothing processing device. Second, condensed water is provided to the water inlet pipe 2 through the water inlet of the detergent box 5, and there is no need to add additional external water pipes to the clothing processing device, which can make full use of existing resources and save costs.

[0972] In some embodiments, the outer tube 1 is provided with a condensation structure, which includes a condensation water inlet, and the connection between the water inlet pipe 2 and the outer tube 1 is directly opposite to the condensation water inlet, so that the liquid in the air permeable tube 4 can flow to the condensation structure through the condensation water inlet.

[0973] Specifically, the condensed water entering the air permeable pipe 4 from the water inlet pipe 2 may finally flow along the inner wall of the outer tube 1 to the drainage structure and be discharged from the drainage structure.

[0974] Furthermore, the present application can also set a condensation water inlet on the original condensation structure of the outer tube 1, so that the condensation water flowing into the outer tube 1 from top to bottom in the air permeable tube 4 flows to the condensation structure, providing additional condensation water for the condensation structure, thereby improving the condensation effect of the condensation structure on humid hot gas.

[0975] In some embodiments, further comprising: a control module; and

[0976] A control valve 6, which is arranged on the water inlet pipe 2 and is used to open or close the water inlet pipe 2;

[0977] Wherein, the control module controls the control valve 6 to open or close the water inlet pipe 2 according to the condensation demand parameter of the gas in the ventilation pipe 4;

[0978] The gas condensation requirement parameters include the gas temperature and / or the gas humidity.

[0979] Specifically, the control valve 6 can be a solenoid valve. The control module can open or close the control valve 6, and further open or close the water inlet pipe 2, so that the water inlet pipe 2 can discharge condensed water to the air pipe 4 or not discharge condensed water as needed. The condensation demand of the gas in the air pipe 4 refers to whether the gas in the air pipe 4 has a higher temperature or a higher humidity. If it has one of a higher temperature and a higher humidity, condensed water is required for condensation, and there is a condensation demand. The condensation demand parameter specifically refers to the temperature and / or gas that affects the condensation demand.

[0980] In some embodiments, the device further comprises: a humidity sensor, which is disposed on the air permeable tube 4 and is used to detect the humidity of the gas in the air permeable tube 4; and

[0981] A temperature sensor is disposed on the air permeable tube 4 and is used to detect the temperature of the gas in the air permeable tube 4;

[0982] The control module controls the control valve 6 to open or close the water inlet pipe 2 according to the condensation demand of the gas in the vent pipe 4, including:

[0983] The water inlet pipe 2 is opened or closed according to the temperature and humidity of the gas in the ventilation pipe 4.

[0984] Specifically, the temperature sensor and the humidity sensor are both fixed on the air pipe 4, and the sensing ends of the temperature sensor and the humidity sensor are both arranged in the air pipe 4. The temperature sensor and the humidity sensor can be used to detect the gas in the air pipe 4 to obtain a temperature signal and a humidity signal; the temperature sensor and the humidity sensor are electrically connected to the control module respectively, and the control module can judge the temperature and humidity in the air pipe 4 according to the temperature signal and the humidity signal sent by the temperature sensor and the humidity sensor, and judge whether the gas in the air pipe 4 needs to be condensed according to the temperature and humidity in the air pipe 4, and then open or close the water inlet pipe 2 to control the condensed water to enter the air pipe 4 or not.

[0985] In some embodiments, opening or closing the water inlet pipe 2 according to the temperature and humidity of the gas in the ventilation pipe 4 includes:

[0986] If the temperature and humidity of the gas in the ventilation pipe 4 are lower than the preset values, the water inlet pipe 2 is closed;

[0987] If either the temperature or the humidity of the gas in the ventilation tube 4 is equal to or higher than a preset value, the water inlet pipe 2 is opened.

[0988] Specifically, the preset value can be a temperature value and a humidity value obtained through calculation or experiment. When the gas temperature and humidity in the ventilation tube 4 are lower than the preset values, the control valve 6 is closed, and the water inlet pipe 2 is disconnected from the ventilation tube 4 to avoid wasting water resources; when either the gas temperature and humidity in the ventilation tube 4 is higher than or equal to the preset value, the control valve 6 is opened, the water inlet pipe 2 is connected to the ventilation tube 4, and condensed water is discharged into the ventilation tube 4, so that the gas in the ventilation tube 4 can combine with the condensed water and condense before entering the exhaust pipe 3 and being discharged into the atmosphere, thereby avoiding the high temperature and humidity of the gas discharged from the clothing processing device, which generates a large amount of water vapor after combining with the colder air outside, affecting the customer's usage experience.

[0989] The embodiment of the present application also provides a control method for a clothes processing device, comprising: an end of a vent pipe 4 away from an outer drum 1 is respectively connected to a water inlet pipe 2 and an exhaust pipe 3, and the control method comprises:

[0990] If the gas in the ventilation tube 4 does not meet the emission standard, the gas in the ventilation tube 4 is condensed.

[0991] Specifically, the emission standard can be a preset temperature and humidity emission standard. When either the temperature or humidity of the gas in the ventilation tube 4 exceeds the preset value, it is determined that the gas in the ventilation tube 4 does not meet the emission standard. As shown in FIG3 , when the gas in the ventilation tube 4 does not meet the emission standard, condensed water is discharged into the ventilation tube 4 through the water inlet pipe 2 to condense the gas in the ventilation tube 4, thereby preventing the temperature or humidity of the gas discharged from the ventilation tube 4 from being too high, thereby affecting the customer's usage experience.

[0992] In some embodiments, if the gas in the vent pipe 4 does not meet the emission standard, it includes:

[0993] The temperature and humidity of the gas in the ventilation tube 4 are obtained. If either the temperature or the humidity reaches a preset value, the gas in the ventilation tube 4 does not meet the emission standard.

[0994] Specifically, when judging whether the gas in the ventilation tube 4 has not reached the discharge surface, the temperature and humidity in the ventilation tube 4 can be obtained by the temperature sensor and the humidity sensor, and then the control module can make a judgment. If either the temperature or the humidity reaches a preset value, that is, equal to or higher than the preset value, it is judged that the gas in the ventilation tube 4 has not reached the discharge standard. The gas in the ventilation tube 4 can be quickly and accurately analyzed and judged so as to perform subsequent operations.

[0995] In some embodiments, obtaining the temperature and humidity of the gas in the ventilation tube 4 includes:

[0996] The temperature and humidity of the gas in the ventilation tube 4 are detected once at a preset time interval.

[0997] Specifically, in the operation step of obtaining the temperature and humidity of the gas in the ventilation tube 4, the gas in the ventilation tube 4 can be detected once every preset time by the temperature sensor and the humidity sensor. The preset time can be set in advance by the control module, which can be once a minute or once half a minute.

[0998] In some embodiments, condensing the gas in the air permeable tube 4 comprises:

[0999] Condensed water is injected into the air permeable tube 4 so that the gas in the air permeable tube 4 contacts the condensed water while flowing upward.

[1000] Specifically, the condensation of the gas in the air tube 4 can be achieved by discharging condensed water into the air tube 4. During the condensation process, the condensed water flows from the top to the bottom of the air tube 4. The volume of the condensed water is not large, and it can be a water flow flowing along the inner wall of the air tube 4. The gas in the air tube 4 flows from bottom to top in the air tube 4. The gas comes into contact with the condensed water during the flow, and relatively dry air can be formed.

[1001] Example 7

[1002] like Figure 7a to Figure 7b As shown, on the one hand, although the clothing processing device in the prior art can heat and increase the temperature of the drying air through the electric heating device and then quickly dry the clothes through the high-temperature drying air, when the drying process is about to end, the moisture content of the clothes in the clothing processing barrel 2 has been greatly reduced compared with before drying, and high-temperature drying air is no longer needed for drying. The subsequent drying effect can also be achieved through the residual heat in the clothing processing barrel 2. At this time, the drying air is still heated at a high temperature, which not only has the risk of damaging the clothes whose moisture content has been greatly reduced relative to before the start of the drying process, but also causes a waste of electricity resources.

[1003] Based on this, as shown in FIG1 , a clothes treating device according to an embodiment of the present invention includes:

[1004] A clothes treatment barrel, comprising an air inlet and an air outlet;

[1005] A drying air duct 1, connected between the air inlet and the air outlet of the laundry processing tub;

[1006] The electric heater 3 is arranged on the drying air duct and is used to provide drying heat for the drying air flow;

[1007] A semiconductor heater 4, which is arranged on the drying air duct and is located downstream of the electric heater and close to the air outlet of the clothes processing barrel;

[1008] A control module is provided, wherein the control module starts the semiconductor heater according to the needs of the drying process.

[1009] Specifically, the drying duct 1 is a high-temperature resistant air passage. The drying duct 1 has an air inlet and an air outlet according to the air flow direction. The air outlet of the drying duct 1 is connected to the air inlet of the clothes processing barrel 2 of the clothes processing device, and can convey drying air to the clothes processing barrel 2. The electric heater 3 and the semiconductor heater 4 are both arranged in the drying duct 1. The electric heater 3 and the semiconductor heater 4 can heat the air in the drying duct 1 to form drying air. The heating effect of the electric heater 3 is stronger than that of the semiconductor heater 4. The semiconductor heater 4 can be a semiconductor heater or other low-power heating equipment. The semiconductor heater 4 consumes less power resources than the electric heater 3, and saves more drying costs. Moreover, the semiconductor heater 4 is arranged between the air outlet of the drying duct 1 and the electric heater 3. At the beginning of the drying program, when low-temperature preheating is performed, the preheating effect of the drying air can be guaranteed. When the drying program is about to end and low-temperature drying is performed, the drying air about to enter the clothes processing barrel 2 can also be heated at a lower temperature, which can ensure that the drying air completes the drying operation of the clothes.

[1010] Among them, when the electric heater 3 reduces the power before the end of drying, although the power can be reduced, the resistance is still in a high temperature state, and it takes a certain amount of time to reduce the temperature to an appropriate range. The semiconductor heater 4 proposed in this application can add a temperature variable to adjust the temperature better and faster, thereby achieving the technical effect of avoiding heat overflow, saving electricity resources, reducing energy consumption, and reducing the risk of clothes being damaged by high temperature.

[1011] Among them, the front air duct of the drying air duct is the condensation air duct, and the rear air duct of the drying air duct is the air inlet duct.

[1012] According to the clothing processing device of the embodiment of the present invention, the semiconductor heater 4 can be used to heat the drying air in the drying air duct 1 at a low temperature. When the clothing processing device just starts the drying program, the semiconductor heater 4 can be used to heat the drying air at a low temperature to make the temperature of the drying air rise smoothly, thereby avoiding direct heating by the electric heater 3, which may cause the temperature of the drying air to rise too high and cause a safety hazard. When the clothing processing device is officially running in the drying program, the electric heater 3 and the semiconductor heater 4 can be turned on at the same time, or the electric heater 3 can be turned on alone to perform rapid drying. Before the drying program of the clothing processing device is about to end, the electric heater 3 is turned off, and the drying air is heated by the semiconductor heater 4, which can avoid heat overflow, save electricity resources, reduce energy consumption, and reduce the risk of clothes being damaged by high temperature.

[1013] In some embodiments, it also includes:

[1014] A front air duct, one end of which is connected to the air inlet of the drying air duct 1, and the other end of which is used to communicate with the air outlet of the clothes processing tub 2; and

[1015] The double-suction fan 5 is arranged in the drying air duct 1 and is located between the air inlet of the drying air duct 1 and the electric heater 3 .

[1016] Specifically, the two ends of the front air duct connect the air inlet of the drying air duct 1 and the clothes processing barrel 2 of the clothes processing device, and the double suction fan 5 can be set at the air inlet of the drying air duct 1 to provide power for air circulation. The front air duct allows the drying air to form a cycle in the clothes processing device. The air is heated in the drying air duct 1 to form drying air, which enters the clothes processing barrel 2, takes away the moisture on the clothes in the clothes processing barrel 2, and then enters the front air duct. Part of the moisture is condensed in the front air duct and then returns to the drying air duct 1. In this cycle, the clothes in the clothes processing barrel 2 can be quickly dried.

[1017] in, Figure 7a The arrows in the diagram represent the direction of air flow.

[1018] In some embodiments, further comprising: a controller;

[1019] A first temperature sensor is disposed in the drying air duct 1 and between the double suction fan 5 and the air inlet of the drying air duct 1. The first temperature sensor is used to detect the return air temperature in the drying air duct 1; and

[1020] A second temperature sensor, which is arranged on the inner side of the outer drum and is used to detect the water temperature in the laundry treatment tub 2;

[1021] The controller controls the start and stop of the electric heater 3 and the semiconductor heater 4 respectively based on the temperature signals fed back by the first temperature sensor and the second temperature sensor.

[1022] Specifically, the controller includes a control unit that can process information and operate other components. The controller can be integrated into the overall control system of the clothing processing device. The first temperature sensor and the second temperature sensor can detect the temperature. The first temperature sensor is arranged in the drying duct 1, between the double suction fan 5 and the drying duct 1, and can detect the return air temperature here. The second temperature sensor is arranged on the inner side of the outer drum, and can detect the water temperature of the clothing processing barrel 2 located in the outer drum; the controller is electrically connected to the first temperature sensor, the second temperature sensor, the electric heater 3 and the semiconductor heater 4 respectively. The controller can control the electric heater 3 and the semiconductor heater 4 based on the temperature signal of the return air temperature fed back by the first temperature sensor and the temperature signal of the inner barrel water temperature fed back by the second temperature sensor, so that the electric heater 3 and the semiconductor heater 4 are turned on or stopped respectively.

[1023] Among them, a small gap is set at the bottom of the inner barrel, and the second temperature sensor is set in the gap. During the drying process, water droplets will fall into the small gap. The second temperature sensor measures the temperature of the small water droplets, which is equivalent to detecting the water temperature of the inner barrel.

[1024] In some embodiments, the semiconductor heating device 4 is a semiconductor heater.

[1025] Specifically, the semiconductor heater 4 can be a semiconductor heater. Compared with the traditional heat energy conversion method, the semiconductor heating technology is more effective. In the semiconductor material, an electric heating metal (such as iron, copper, etc.) is used to be heated under the action of electric current to generate high temperature, which is converted into useful heat energy. The advantage of the semiconductor heater is that it can quickly complete heating and constant temperature in a short time, and can adjust the heat energy within a precise temperature range, thereby improving the utilization rate of heat energy, saving power resources, and saving drying costs.

[1026] The embodiment of the present application also provides a control method of a clothes processing device, comprising: heating the drying air at a high temperature to dry the clothes in the clothes processing barrel 2;

[1027] If the clothes in the clothes processing tub 2 reach a preset drying degree, the drying air is heated at a low temperature instead.

[1028] Specifically, when drying clothes, the air in the drying duct 1 can be heated at high temperature by the electric heater 3 in the clothes processing device to form high-temperature drying wind, and the high-temperature drying wind enters the clothes processing barrel 2 to take away the moisture of the clothes in the clothes processing barrel 2, thereby realizing rapid drying of the clothes; after the drying wind is heated at high temperature for a period of time, the high-temperature drying wind has taken away most of the moisture in the clothes, and when there is not much moisture left to be dried, the temperature in the clothes processing barrel 2 is sufficient to complete the remaining drying work, and the drying wind at this time no longer needs to be heated at high temperature, and as long as it continues to circulate, the remaining moisture to be dried can be taken away, the electric heater 3 is stopped, the drying wind is no longer heated at high temperature, and the semiconductor heater 4 is started to heat the drying wind at a lower temperature, which can effectively utilize thermal energy, save electricity resources, and reduce the cost of drying clothes.

[1029] Compared with heating and drying by using the semiconductor heater 4 alone, the control method proposed in the present application will not significantly reduce the drying efficiency, increase the drying time, and affect the customer's experience. Compared with heating and drying by using the electric heater 3 alone, the drying air will not be kept at a high temperature all the time, causing damage to the clothes after a large amount of moisture has been reduced. It can also save electricity appropriately and reduce drying costs.

[1030] In some embodiments, the drying air is heated at a high temperature, including:

[1031] The electric heater 3 is turned on, or the electric heater 3 and the semiconductor heater 4 are turned on.

[1032] Specifically, when the drying air is heated at high temperature, the electric heater 3 can be turned on alone to quickly heat up the air in the drying air duct 1, or the electric heater 3 and the semiconductor heater 4 can be turned on together to increase the heating effect, reduce the time required for drying, and improve the customer's experience.

[1033] In some embodiments, if the clothes in the clothes processing barrel 2 reach a preset drying degree, the drying air is heated at a low temperature, including:

[1034] If the difference between the return air temperature and the water temperature of the laundry processing tub 2 reaches a first preset value, the electric heater 3 is turned off and the semiconductor heater 4 is turned on to slowly reduce the temperature of the drying air.

[1035] Specifically, the difference between the return air temperature and the water temperature of the clothes treatment barrel 2 can be used to determine whether the temperature of the clothes treatment barrel 2 is sufficient to complete the remaining drying work. Specifically, after the drying air enters the front air duct from the air outlet of the clothes treatment barrel 2, it will become humid hot air. The humid hot air passes through the front air duct, condenses water and hot air, and the heat is taken away. At this time, the air flows back to the double suction fan 5. The return air temperature is the temperature of the air flowing back here. When the moisture content of the clothes in the clothes treatment barrel 2 gradually decreases, the difference between the return air temperature and the water temperature will gradually increase. When a certain value is reached, the clothes are dried. A first preset value can be obtained in advance through calculation and experiment. The first preset value is input into the controller during drying. When the difference between the return air temperature and the water temperature of the inner barrel gradually increases and reaches the first preset value, it is determined that the temperature in the clothes treatment barrel 2 is sufficient to complete the remaining drying work. At this time, the electric heater 3 is turned off, and the semiconductor heater 4 is turned on to start low-temperature heating to save electricity, so that the temperature of the drying air is slowly reduced, so that the drying air with a certain amount of residual heat continues to circulate while being able to dry the clothes in the inner barrel.

[1036] In some embodiments, the drying air is heated at a high temperature to dry the clothes in the clothes processing tub 2, and the method also includes:

[1037] The drying air is preheated at a low temperature so that the temperature of the drying air rises smoothly.

[1038] Specifically, before the drying air is heated at high temperature and the clothes are dried, the drying air can be preheated at low temperature by the semiconductor heater 4. The semiconductor heater 4 can make the temperature of the drying air rise smoothly and will not make the temperature of the drying air too high. Since the clothes in the clothes processing barrel 2 are in a relatively moist state before being dried, turning on the semiconductor heater 4 at this time to preheat the clothes in the barrel can avoid the temperature being too high when the electric heater 3 is turned on, causing damage to the clothes. In addition, the instantaneous opening of the electric heating device and the instantaneous increase in temperature can easily cause the first temperature sensor and the second temperature sensor to misjudge, thereby affecting the original drying program.

[1039] In some embodiments, low-temperature preheating to increase the temperature of the drying air smoothly includes:

[1040] Only the semiconductor heater 4 is turned on to slowly increase the temperature of the drying air until the difference between the return air temperature and the water temperature of the clothes processing tub 2 reaches a second preset value.

[1041] Specifically, a second preset value can be pre-entered in the controller. During the low-temperature preheating process, only the semiconductor heater 4 is turned on for heating, and the controller can obtain the return air temperature and the water temperature of the clothing processing tub 2 through the first temperature sensor and the second temperature sensor. When the difference between the return air temperature and the water temperature of the clothing processing tub 2 reaches the second preset value, it means that the preheating has been roughly completed and the drying air has taken away a certain amount of water vapor. At this time, the controller automatically controls the electric heater 3 to start, heat the drying air at high temperature, and enter the formal heating and drying state.

[1042] In some embodiments, if the temperature in the laundry processing tub 2 is sufficient to complete the remaining drying work, the drying air is heated at a low temperature, and then the following steps are further included:

[1043] If the difference between the return air temperature and the water temperature of the laundry processing tub 2 reaches a third preset value, the drying is stopped.

[1044] Specifically, a third preset value can be pre-input into the controller. When the difference between the return air temperature obtained by the controller and the water temperature of the clothing processing barrel 2 reaches the third preset value, it means that the drying operation of the clothes in the clothing processing barrel 2 has been completed. At this time, the controller controls the semiconductor heater 4 to stop working to avoid wasting electricity and to avoid damage to clothes by the continuous flow of drying air. The controller can also turn on the warning light and / or sound an alarm at this time to remind the user that the drying has been completed and to take timely measures.

[1045] When the controller determines the difference between the return air temperature and the inner barrel temperature, it may perform detection and determination once a minute.

[1046] Example 8

[1047] The following is combined with Figure 8a-8i The technical solution of this embodiment is elaborated in detail. In the absence of conflict, the following implementation methods and embodiments can be combined with each other.

[1050] A first filter element 1 and a second filter element 2 are stacked, the first filter element 1 is provided with a plurality of adjacent first pore channels 11, the second filter element 2 is provided with a plurality of adjacent second pore channels 21, and a plurality of airflow channels 3 are formed between the plurality of adjacent first pore channels 11 and the plurality of adjacent second pore channels 11;

[1051] One of the first filter element 1 and the second filter element 2 can be driven to rotate relative to the other to change the number of airflow channels 3 and the total flow area of ​​multiple airflow channels 3, wherein the number of airflow channels 3 and the total flow area of ​​multiple airflow channels 3 are negatively correlated.

[1052] That is, in the embodiment of the present invention, by moving one of the first filter element 1 and the second filter element 2 relative to the other, the number of multiple airflow channels 3 formed between the multiple first pore channels 11 and the multiple second pore channels 21 can be changed, and when the number of multiple airflow channels 3 changes, the corresponding total flow area of ​​the multiple airflow channels 3 will also change, thereby changing the ventilation volume of the filter component per unit time, thereby realizing the adjustment of the air volume by the filter component.

[1053] For ease of understanding, the stacked first filter element 1 and the second filter element 2 can be regarded as an integral filter component, wherein the airflow channel 3 can serve as the airflow channel of the integral filter component. When the total flow area of ​​the airflow channel 3 on the integral filter component changes, the ventilation volume of the integral filter component per unit time can be changed, thereby realizing the adjustment of the air volume by the filter assembly.

[1054] Further, such as Figure 8a-8d As shown, a first channel wall 12 is provided between two adjacent first pore channels 11, and a second channel wall 22 is provided between two adjacent second pore channels 21;

[1055] When one of the first filter element 1 and the second filter element 2 is driven to rotate relative to the other, in the airflow direction of the airflow channel 3, the first channel wall 12 and the second channel wall 22 can overlap each other or form a certain angle between the two.

[1056] Among them, when the first channel wall 12 and the second channel wall 22 overlap each other, the total air intake area of ​​the multiple air flow channels 3 is the largest, and when the first channel wall 12 and the second channel wall 22 are vertically arranged at an angle of 90 degrees, the total air intake area of ​​the multiple air flow channels 3 is the smallest.

[1057] Specifically, Figure 8c , Figure 8c A first top view structural schematic diagram is shown when the first filter element 1 and the second filter element 2 are stacked together. Since the first channel wall 12 on the first filter element 1 and the second channel wall 22 on the second filter element 2 overlap with each other in the flow direction of the airflow at this time, the number of airflow channels 3 at this time is the least. Correspondingly, since the first channel wall 12 on the first filter element 1 does not block the second pore channel 21 on the second filter element 2 and the second channel wall 22 on the second filter element 2 does not block the first pore channel 11 on the first filter element 1, the total flow area of ​​the multiple airflow channels 3 at this time is the largest, that is, the air intake of the filter assembly per unit time is the largest at this time.

[1058] More specifically, Figure 8d As shown, Figure 8d A second top view schematic diagram showing a structure in which the first filter element 1 and the second filter element 2 are stacked together { Figure 8d The status is Figure 8c In the state, one of the filter elements is rotated 90° clockwise or 90° counterclockwise relative to the other filter element. Since the first channel wall 12 on the first filter element 1 and the second channel wall 22 on the second filter element 2 are perpendicular to each other at this time, the number of airflow channels 3 is the largest at this time. Correspondingly, since the first channel wall 12 on the first filter element 1 blocks the second pore channel 21 on the second filter element 2 and the second channel wall 22 on the second filter element 2 blocks the first pore channel 11 on the first filter element 1, the total flow area of ​​the multiple airflow channels 3 at this time is the smallest, that is, the air intake of the filter assembly per unit time is the smallest at this time.

[1059] It is worth noting that if Figure 8c and Figure 8d As shown, the filter component consists of Figure 8c The state changes to Figure 8d In the state, the number of air flow channels 3 of the filter assembly gradually increases, and the total flow area of ​​the multiple air flow channels 3 on the filter assembly gradually decreases.

[1060] In this way, when the filter assembly is used, the air intake volume per un...
