Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a clothing processing device and a method for controlling the air intake of the clothing processing device. Background Technology

[0002] Current clothing drying devices, such as dryers and washer-dryer combos, mostly use condenser drying. The hot and humid air in the clothes processing drum is condensed by condenser water, then heated by a fan and heater, and then the dry and hot air is blown into the drum to complete the circulation.

[0003] However, the air inside the garment processing drum is sealed, which may lead to problems such as strong odor and excessive temperature. Summary of the Invention

[0004] To overcome the problems existing in related technologies, embodiments of the present invention propose a garment processing device and an air intake control method for the garment processing device.

[0005] The first aspect of this invention provides a garment processing device, comprising:

[0006] Clothing handling drum;

[0007] The drying air duct has an air inlet and an air outlet that are connected to the clothes handling drum.

[0008] The fan is connected to the drying duct and is used to provide airflow circulation power. The fan is a dual-inlet fan, which includes a first air inlet and a second air inlet. The first air inlet is used to draw airflow from the clothes handling drum into the drying duct, and the second air inlet is used to draw fresh air from outside the clothes handling drum into the drying duct.

[0009] An air vent control device is located at the second air intake. The air vent control device includes multiple window slats arranged around the center of the second air intake, and the multiple window slats can be controlled to rotate synchronously.

[0010] When multiple window blades are controlled to rotate synchronously, they can open or close the second air intake. When multiple window blades open the second air intake, an airflow channel connected to the second air intake can be defined between two adjacent window blades. The cross-sectional area and airflow direction of the airflow channel can change as the rotation angle of the window blades changes.

[0011] In the above technical solution, the clothing processing equipment also includes a heating device, which is located in the drying air duct and between the second air inlet and the air outlet of the drying air duct.

[0012] When the second air intake is opened, the air intake direction of the airflow channel formed between two adjacent window slats intersects with the axis of the second air intake.

[0013] In the above technical solution, the window leaf includes a head and a tail. When multiple window leaves are controlled to rotate synchronously, the multiple window leaves can be connected head to tail in the circumferential direction of the second air intake to close the second air intake.

[0014] In the above technical solution, the fan also includes a fan shroud surrounding the second air inlet, and the air inlet control device also includes a drive unit located at the center of the second air inlet, wherein the second air inlet is formed between the fan shroud and the drive unit.

[0015] The window blade includes an blade shaft and blades. One end of the blade shaft is rotatably mounted on the outer periphery of the drive unit, and the other end extends to the upper surface of the wind shield. The drive unit can drive the blade shaft to rotate, and the blades are fixed on the outer periphery of the blade shaft.

[0016] Multiple blade shafts can be controlled to rotate synchronously, thereby driving multiple blades to rotate synchronously. When multiple blades rotate synchronously, an airflow channel communicating with the second air inlet can be defined between two adjacent blades. When the blade rotation angle changes, the cross-sectional area of ​​the airflow channel and the air inlet direction can change.

[0017] In the above technical solution, the diameter of the blade shaft is greater than the thickness of the blade.

[0018] In the above technical solution, the fan includes a fan casing and fan blades disposed inside the fan casing.

[0019] The top of the fan casing forms a second air inlet, and the air inlet control device also includes a drive unit located at the center of the second air inlet, with multiple window blades arranged around the outer periphery of the drive unit.

[0020] The drive unit can drive multiple window leaf blades to rotate synchronously;

[0021] The fan also includes a shroud surrounding the second air inlet, wherein the second air inlet is formed between the shroud and the drive unit.

[0022] In the above technical solution, the garment processing equipment also includes:

[0023] Temperature sensor, used to detect the temperature value in the garment processing drum;

[0024] The controller can control the rotation angle of the window slats based on the temperature value.

[0025] In the above technical solution, the garment processing equipment also includes:

[0026] Humidity sensor, used to detect the humidity level of the external environment;

[0027] An air quality sensor is used to detect the quality of the outside air.

[0028] The controller can control the opening and closing of the air vent control device based on the ambient humidity and air quality values.

[0029] A second aspect of this invention provides an air intake control method for a garment processing device, applied to the aforementioned garment processing device. The air intake control method includes:

[0030] In drying mode, the temperature value inside the clothes processing drum is obtained, and the louvers are controlled to open at the target angle based on the temperature value inside the clothes processing drum.

[0031] In the above technical solution, the method of controlling the window slats to open at a target angle based on the temperature value in the garment processing drum includes:

[0032] When the temperature in the garment processing drum reaches the first preset threshold, the window leaf is controlled to rotate and open at the first angle.

[0033] When the temperature in the garment processing drum reaches the second preset threshold, the window leaf is controlled to rotate and open at the second angle.

[0034] The first preset threshold is greater than the second preset threshold, and the first angle is greater than the second angle.

[0035] In the above technical solutions, the air intake control method also includes:

[0036] In drying mode, the ambient temperature and air quality values ​​are acquired, and the opening and closing of the air vent control device are controlled based on the ambient temperature and air quality values.

[0037] When the air vent control device is shut down, the second air intake is also shut down.

[0038] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0039] In this embodiment of the invention, the existing fan system in the garment processing equipment is replaced with a dual-intake fan. The second air inlet of the dual-intake fan is outside the duct system and is used to introduce fresh air, while the first air inlet is inside the duct system and is used to draw in the airflow from the garment processing drum. Simultaneously, an adjustable-angle window slat structure is installed at the fresh air inlet position of the dual-intake fan, ensuring that the amount of fresh air introduced can be varied while maintaining the original internal circulation airflow.

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0047] Current clothing drying devices, such as dryers and washer-dryer combos, mostly use condenser drying. Hot, humid air inside the clothes processing drum is condensed by condensate water, then heated by a fan and heater before being blown back into the drum to complete the circulation. However, the closed-loop airflow inside the clothes processing drum can lead to problems such as strong odors and overheating during drying. In this invention, the existing fan system in the clothes processing equipment is replaced with a dual-intake fan. Half of the air inlet of the dual-intake fan is outside the duct system for introducing fresh air, while the other half is inside the duct system. Simultaneously, an adjustable-angle louver structure is installed at the fresh air inlet of the dual-intake fan, ensuring that the amount of fresh air introduced can be varied without changing the original internal circulation airflow.

[0048] The following is in conjunction with the appendix Figure 1-3 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0049] Example

[0050] like Figures 2-3 As shown, a first aspect of the present invention provides a garment processing device, comprising:

[0051] Clothing handling drum (not shown in the picture);

[0052] The drying air duct has an air inlet and an air outlet that are connected to the clothes handling drum.

[0053] like Figure 2 and Figure 3 The fan 1 shown is connected to the drying duct and is used to provide airflow circulation power. The fan 1 is a dual-inlet fan, which includes a first air inlet and a second air inlet 11. The first air inlet is used to draw airflow from the clothes handling drum into the drying duct, and the second air inlet 11 is used to draw fresh air from outside the clothes handling drum into the drying duct.

[0054] An air vent control device is located at the second air intake 11. The air vent control device includes multiple window blades 2 arranged around the center of the second air intake 11, and the multiple window blades 2 can be controlled to rotate synchronously.

[0055] When multiple window blades 2 are controlled to rotate synchronously, they can open or close the second air intake 11. When multiple window blades 2 open the second air intake 11, an airflow channel connected to the second air intake 11 can be defined between two adjacent window blades 2. The cross-sectional area and air intake direction of the airflow channel can change with the rotation angle of the window blades 2.

[0056] In this embodiment of the invention, the existing fan system in the garment processing equipment is replaced with a dual-intake fan. Half of the air inlet of the dual-intake fan is outside the duct system for introducing fresh air, and the other half is inside the duct system. Meanwhile, as... Figure 1 As shown, in this embodiment of the invention, an adjustable-angle window blade 2 structure is installed at the fresh air inlet position of the existing dual-inlet fan 1', based on the existing dual-inlet fan 1', which can ensure that the fresh air volume can be changed while the original internal circulation air volume remains unchanged.

[0057] Specifically, when the garment processing equipment is performing the drying program, when the temperature inside the garment processing drum reaches a relatively high temperature, the required air volume inside the garment processing drum increases. By controlling the rotation of the window blades, an airflow channel is formed between two adjacent window blades 2 that is connected to the second air intake (i.e., the fresh air inlet) 11. Fresh air from the outside can enter the drying air duct through the second air intake 11 and flow into the garment processing drum to improve drying efficiency.

[0058] It should be noted that when the temperature inside the clothes processing drum reaches a relatively high temperature, the rotation of window slat 2 can be maximized when controlling its rotation. The larger the rotation angle of window slat 2, the greater the amount of fresh air entering. {Note: The rotation angle of window slat 2 is relative to when window slat 2 is closed, i.e., when...} Figure 2 As shown, when window leaf 2 is closed, its rotation angle is 0. When window leaf 2 is open, as... Figure 3 As shown, the angle of the window leaf 2 changes, and the larger the window leaf 2 opens, the greater the rotation angle, thereby maximizing drying efficiency when the temperature inside the clothes processing drum reaches a higher temperature.

[0059] More specifically, as drying time increases, the clothes in the clothes processing drum gradually become drier. Towards the end of the drying process, the louvers can be rotated to reduce their angle, decreasing the amount of fresh air and thus reducing heat exchange between the recirculated air and the fresh air. This lowers the temperature inside the clothes processing drum, reducing damage to the clothes caused by over-drying and reducing the energy consumption of the heating element in the drying unit. Furthermore, the relatively dry recirculated air results in less heat loss, which helps improve drying efficiency.

[0060] It should also be noted that, Figure 1 The dual-suction fan shown is based on the original fan. An opening connecting to the outside is added to the axial position of the fan blades at the motor cover of the volute assembly. An additional fan blade is added to increase the efficiency of introducing fresh air and increase the airflow velocity within the duct system. When the fan is operating, in addition to the original internal circulation, fresh air can be introduced into the internal circulation, increasing the air volume, reducing the fan load, and further improving the drying efficiency of the duct assembly.

[0061] In the embodiments of the present invention Figure 2 and Figure 3 The dual suction fan shown is in Figure 1 An additional window louver structure was added to the medium-duty suction fan.

[0062] In any of the above embodiments, the garment processing equipment further includes a heating device, which is disposed in the drying air duct and located between the second air inlet 11 and the air outlet of the drying air duct.

[0063] When the second air intake 11 is opened, the air intake direction of the airflow channel formed between two adjacent window blades 2 intersects with the axis of the second air intake.

[0064] In this embodiment of the invention, by tilting the air intake angle of the airflow channel formed between two adjacent window blades 2 towards the second air inlet 11, when the airflow enters the second air inlet 11 from the airflow channel, the fresh air can mix with the circulating airflow in the clothes processing drum in the form of turbulence, thereby improving the mixing effect of the two airflows with different temperatures {the airflow in the clothes processing drum has a higher temperature, and the fresh air has a lower temperature}, thereby avoiding the uneven mixing of the two airflows from affecting the service life of the heating device {if the two airflows with different temperatures are not mixed evenly, then the mixed airflow of one cold and one hot will affect the service life of the heating device when it passes through the heating device}.

[0065] In any of the above embodiments, the window leaf 2 includes a head and a tail. When multiple window leaves 2 are controlled to rotate synchronously, the multiple window leaves 2 can sequentially engage head-to-tail in the circumferential direction of the second air intake 11 to close the second air intake 11, i.e., as shown... Figure 2 As shown.

[0066] In any of the above embodiments, the window leaf 2 includes a first leaf surface and a second leaf surface that are formed opposite to each other;

[0067] When an airflow channel is defined between two adjacent window blades 2, the first surface of one window blade 2 and the second surface of the other window blade 2 serve as the channel surface of the airflow channel.

[0068] In this embodiment of the invention, by using the surfaces of two adjacent window blades as the channel surfaces of the airflow channel, the cross-sectional area of ​​the airflow channel can be changed and the fresh air intake volume can be changed by rotating the window blades. On the other hand, the air intake direction of the airflow channel can be changed by rotating the window blades. Furthermore, by using the surfaces of the window blades as the channel surfaces, the generation of large noise when the airflow passes through the window blades can be avoided.

[0069] In any of the above embodiments, such as Figure 2 and Figure 3 As shown, the fan also includes a fan shroud 4 surrounding the second air inlet, and the air inlet control device also includes a drive unit 3 located at the center of the second air inlet 11, wherein the second air inlet 11 is formed between the fan shroud 4 and the drive unit 3.

[0070] The window blade 2 includes a blade shaft 21 and blades 22. One end of the blade shaft 21 is rotatably disposed on the outer periphery of the drive unit 3, and the other end extends to the upper end surface of the wind shield 4. The drive unit can drive the blade shaft 21 to rotate, and the blades 22 are fixed on the outer periphery of the blade shaft 21.

[0071] Multiple blade shafts 21 can be controlled to rotate synchronously, thereby driving multiple blades 22 to rotate synchronously. When multiple blades 22 rotate synchronously, an airflow channel communicating with the second air intake 11 can be defined between two adjacent blades 22. When the rotation angle of the blades 22 changes, the cross-sectional area of ​​the airflow channel and the air intake direction can change.

[0072] In this embodiment of the invention, by using the blade shaft 21 as the drive shaft, it is easy to connect multiple window blades 2 to the drive structure so that multiple window blades can be driven to rotate synchronously by a single drive mechanism.

[0073] Specifically, the drive unit 3 can be a gear meshing transmission structure or a chain transmission mechanism, but it is not limited to the above transmission mechanisms. Any transmission mechanism that can drive multiple window leaves 2 to rotate at the same time is acceptable. The specific structure of the transmission mechanism will not be described in detail in this embodiment of the invention.

[0074] In any of the above embodiments, such as Figure 2 and Figure 3 As shown, the diameter of the blade shaft 21 is greater than the thickness of the blade 22. In this embodiment of the invention, the advantage of setting the diameter of the blade shaft 21 to be greater than the thickness of the blade 22 is that it can block and intercept dust and impurities mixed in with the fresh air during the introduction of fresh air. Specifically, for example… Figure 2 and Figure 3 As shown, when fresh air enters the fan through two adjacent window blades 2, it flows from one side of the blade 22 to the side of the blade shaft 21. In this embodiment of the invention, by setting the diameter of the blade shaft 21 to be relatively large, a barrier rib can be formed at the end of the airflow channel to intercept impurities mixed in the fresh air and prevent impurities from entering the fan.

[0075] In any of the above embodiments, the garment processing device further includes:

[0076] Temperature sensor, used to monitor the temperature value in the garment processing drum;

[0077] The controller can control the rotation angle of the window leaf 2 according to the temperature value.

[0078] Specifically, when the clothing processing equipment is performing the drying program, when the temperature inside the clothing processing drum is detected to have reached a high temperature, the window blades can be rotated to form an airflow channel between two adjacent window blades 2 that is connected to the second air intake (i.e., the fresh air inlet) 11. Fresh air from the outside can enter the drying air duct through the second air intake 11 and flow into the clothing processing drum to improve drying efficiency.

[0079] More specifically, as the drying time increases, the clothes in the clothes processing drum gradually become drier. When a temperature drop is detected in the drum, indicating the drying process is in its later stages, the louvers can be rotated to reduce their angle. This decreases the amount of fresh air, reducing heat exchange between the recirculated air and the fresh air, thus lowering the temperature inside the drum. This reduces damage to the clothes caused by over-drying and also reduces the energy consumption of the heating element in the drying unit. Furthermore, the relatively dry recirculated air results in less heat loss, which helps improve drying efficiency.

[0080] Furthermore, the garment processing equipment also includes:

[0081] Humidity sensor, used to detect the humidity level of the external environment;

[0082] An air quality sensor is used to detect the quality of the outside air.

[0083] The controller can control the opening and closing of the air vent control device based on the ambient humidity and air quality values.

[0084] Specifically, when the ambient humidity or pollution level is high (exceeding the set threshold), the air vent control device will close, essentially functioning as a basic fan circulating air within the clothes processing drum. This avoids increasing the burden on the heating element in the drying duct due to the introduction of high-humidity fresh air, prevents waste of condensate, and avoids damage to clothes in the processing drum from highly polluted fresh air. When the ambient environment is stable, other opening / closing options can be selected to introduce fresh air.

[0085] A second aspect of this invention also provides an air intake control method for a garment processing device, applied to the aforementioned garment processing device. The air intake control method includes:

[0086] In drying mode, the temperature value in the clothes processing drum is obtained, and the window leaf 2 is controlled to open at the target angle based on the temperature value in the clothes processing drum.

[0087] Specifically, when the temperature in the clothing processing drum reaches the first preset threshold, the control window leaf 2 is rotated to open the window leaf 2 at the first angle;

[0088] When the temperature in the clothing processing drum reaches the second preset threshold, control the window leaf 2 to rotate so that the window leaf 2 opens at the second angle;

[0089] The first preset threshold is greater than the second preset threshold, and the first angle is greater than the second angle.

[0090] Specifically, when the clothing processing equipment executes the drying program, when the temperature inside the clothing processing drum is detected to reach the first preset threshold, the window blades are controlled to rotate, so that an airflow channel is formed between two adjacent window blades 2 that is connected to the second air intake (i.e., fresh air inlet) 11. Fresh air from the outside can enter the drying air duct through the second air intake 11 and flow into the clothing processing drum to improve drying efficiency.

[0091] More specifically, as the drying time increases, the clothes in the clothes processing drum gradually become drier. When the temperature inside the drum reaches the second preset threshold, indicating the drying process is in its later stages, the louvers are rotated to reduce their angle. This decreases the amount of fresh air, thereby reducing heat exchange between the recirculated air and the fresh air, thus lowering the temperature inside the drum. This reduces damage to the clothes caused by over-drying and also reduces the energy consumption of the heating element in the drying unit. Furthermore, the relatively dry recirculated air results in less heat loss, which helps improve drying efficiency.

[0092] It should be noted that the above-mentioned air intake control method also includes: in drying mode, acquiring the ambient temperature value and the ambient air quality value, and controlling the opening and closing of the air outlet control device based on the ambient temperature value and the ambient air quality value.

[0093] When the air vent control device is shut down, the second air intake is also shut down.

[0094] When drying clothes, if high humidity or high pollution levels are detected in the external environment, the air vent control device will close, essentially functioning as a basic fan circulating air within the clothes drying drum. This avoids increasing the burden on the heating element in the drying duct by introducing high-humidity fresh air, prevents waste of condensate, and avoids damage to the clothes in the drum from highly polluted fresh air. When the external environment is stable, other opening / closing options can be selected to introduce fresh air.
