[0071] In this embodiment of the invention, a drying device 2 is introduced. The drying device 2 is applied to clothing processing equipment such as washer-dryer combos or dryers, and is used to dry clothing.

[0072] The drying device 2 includes at least a drying module 2-1 and a fan module 2-2. The drying module 2-1 includes a drying air duct, a heater 2-12 and a drying filter device 2-11 installed in the drying air duct. The upper and lower walls of the drying air duct are provided with guide rails for installing the drying filter device 2-11. The drying filter device can be pulled back and forth along the guide rails. The air entering the drying module 2-1 passes through the drying filter device 2-11 and the heater 2-12 in sequence before entering the drum module for holding clothes to dry the clothes.

[0073] Although the drying filter device 2-11 can effectively filter lint, after prolonged use, lint will still accumulate in the heater 2-12. This requires the entire machine to be returned to the factory for repair, affecting the user experience and incurring high maintenance costs.

[0074] This embodiment mainly provides a drying device 2 that facilitates the cleaning of lint from the heater 2-12 of the drying device 2.

[0075] Example 1

[0076] like Figures 1 to 13 As shown in the embodiment of the present invention, a drying device 2 is introduced.

[0077] The drying device 2 includes a drying air duct and a heater 2-12 installed in the drying air duct. The heater 2-12 is used to heat the drying airflow to dry the clothes.

[0078] like Figure 8 and Figure 9 As shown, the side wall of the drying duct is provided with a maintenance opening 2-101 corresponding to the heater 2-12, and a cover 2-13 for opening / closing the maintenance opening 2-101. When there is lint accumulated inside the heater 2-12 of the drying device 2, the user or maintenance personnel can open the cover 2-13 and maintain the heater 2-12 through the maintenance opening 2-101. The lint can be cleaned from the heater 2-12 using a brush, hook, or water gun to ensure drying efficiency and safety, improve the convenience of inspecting and maintaining the heater 2-12, and enhance the user experience.

[0079] In some specific embodiments, a temperature sensor is provided on the cover 2-13. The temperature sensor is located on the side of the cover 2-13 facing away from the heater 2-12 and corresponds to the heater 2-12, and is used to detect the temperature of the cover 2-13.

[0080] Specifically, when wire shavings accumulate inside the heater 2-12, the temperature at the heater 2-12 will rise. By setting a temperature sensor on the cover 2-13, the temperature of the cover 2-13 can be obtained to determine the blockage of the heater 2-12. The control unit can then determine whether the heater 2-12 needs to be cleaned based on the temperature sensor's detection. When the temperature is too high, the control unit will stop the operation of the drying device 2 based on the temperature sensor's detection result to prevent the wire shavings from igniting and improve safety.

[0081] In this embodiment, a protective cover 2-14 is provided on the cover 2-13. The temperature sensor is fixed to the side of the cover 2-13 facing away from the heater 2-12 through the protective cover 2-14. At the same time, the protective cover 2-14 can protect the temperature sensor.

[0082] In some specific embodiments, a mounting groove 2-103 is provided on the side of the cover 2-13 facing away from the heater 2-12. The shape of the mounting groove 2-103 is adapted to the shape of the temperature sensor to accommodate the temperature sensor, which is disposed within the mounting groove 2-103. The protective cover 2-14 is fastened onto the mounting groove 2-103, and the protective cover 2-14 is fixedly connected to the cover 2-13, confining the temperature sensor within the mounting groove 2-103. Simultaneously, a relatively enclosed space is formed between the protective cover 2-14 and the mounting groove 2-103, which can prevent the temperature outside the drying air duct from affecting the detection results of the temperature sensor, enabling the temperature sensor to accurately detect the temperature of the cover 2-13.

[0083] Preferably, the cover is groove-shaped and at least partially fitted around the outer periphery of the mounting groove; the side of the cover and / or the mounting groove is provided with a lead-in port, from which the temperature sensor's wiring is led out.

[0084] In some specific embodiments, the cover 2-13 is provided with a first annular rib extending away from the heater 2-12 in the middle, and the first annular rib and the cover 2-13 form an installation groove 2-103; the cover 2-14 is provided with a second annular rib extending from the cover 2-14 towards the cover 2-13 and surrounding the first annular rib.

[0085] In this embodiment, the first annular rib extends outward from the cover 2-13 in a direction perpendicular to the cover 2-13, the inner wall shape of the second annular rib is adapted to the outer wall shape of the first annular rib, and the second annular rib is sleeved on the first annular rib, so that a relatively closed space is formed between the cover 2-13 and the cover 2-14 for accommodating the temperature sensor.

[0086] In this embodiment, the cover 2-13 and the protective cover 2-14 can be detachably connected by any possible installation method.

[0087] Preferably, in the embodiment, the cover 2-14 and the cap 2-13 are connected by screws.

[0088] In some specific embodiments, the cover 2-14 is provided with at least one ear plate on its side, and the cover 2-13 is provided with a screw post corresponding to the ear plate. A screw adapted to the screw post passes through the ear plate and is tightened on the screw post, thereby fixing the cover 2-14 to the cover 2-13.

[0089] Specifically, grooves are provided on the first and second annular ribs at their interlocking ends. These grooves interlock to form a lead-in port for the temperature sensor's wiring to pass through. The temperature sensor's wiring includes power lines and signal lines. The temperature sensor is electrically connected to the control computer board of the garment processing equipment.

[0090] like Figure 11 As shown, in some specific embodiments, the cover 2-13 is also provided with a wiring section for guiding and fixing the circuit of the temperature sensor.

[0091] Specifically, the wiring section includes a first wiring section 2-15 disposed on the cover 2-14, and / or a second wiring section 2-16 disposed on the cover 2-13.

[0092] In this embodiment, the first wiring portion 2-15 is located at the end of the cover 2-14 and is annular. The first wiring portion 2-15 and the lead-in port are located at the same end of the cover 2-14. The wire of the temperature sensor is led out from the lead-in port and fixed by the first wiring portion 2-15. Preferably, the first wiring portion 2-15 protrudes outward from the end of the cover 2-14, and the annular first wiring portion 2-15 has an opening on the side opposite to the wiring direction, through which the wire is inserted into the first wiring portion 2-15.

[0093] The second wiring portion 2-16 is disposed on the outer edge of the cover 2-13. The second wiring portion 2-16 includes a first limiting rib 2-161 disposed opposite to the outer edge of the cover 2-13, a second limiting rib 2-162 connected between the outer edge of the cover 2-13 and the first limiting rib 2-161, a third limiting rib 2-163 extending from the outer edge of the cover 2-13 toward the first limiting rib 2-161 and spaced apart from the first limiting rib 2-161, and a fourth limiting rib 2-164 extending from the first limiting rib 2-161 toward the cover 2-13 and spaced apart from the cover 2-13; the third limiting rib 2-163 and the fourth limiting rib 2-164 are parallel and spaced apart from the second limiting rib 2-162.

[0094] Specifically, such as Figure 11 As shown, the second wiring portion 2-16 is disposed on the outer edge of the cover 2-13. The first limiting rib 2-161 is a flat plate opposite to the outer edge of the cover 2-13. The second limiting rib 2-162 is disposed between one side of the first limiting rib 2-161 and the outer edge of the cover 2-13. The third limiting rib 2-163 and the fourth limiting rib 2-164 are disposed on the side opposite to the side of the first limiting rib 2-161 where the second limiting rib 2-162 is disposed, and are disposed between the outer edge of the cover 2-13 and the second limiting rib 2-162. The second limiting rib 2-162, the third limiting rib 2-163, and the fourth limiting rib 2-164 are interleaved, and at least two of them are disposed. The temperature sensor's circuitry is inserted into the space enclosed by the first limiting rib 2-161, the second limiting rib 2-162, the third limiting rib 2-163, the fourth limiting rib 2-164, and the outer edge of the cover 2-13 at the interval between the fourth limiting rib 2-164 and the cover 2-13, and at the interval between the third limiting rib 2-163 and the first limiting rib 2-161, thereby limiting the circuitry.

[0095] Preferably, in this embodiment, the first wiring portion 2-15 and the second wiring portion 2-16 are arranged sequentially along the wiring direction of the temperature sensor's circuit.

[0096] like Figures 7 to 9 ,and Figure 12As shown, in some specific embodiments, the cover 2-13 is disposed on the outer wall of the drying air duct, and the side wall of the drying air duct is provided with an annular sealing groove 2-17 extending around the maintenance opening 2-101, and a sealing strip 2-102 is disposed in the annular sealing groove 2-17; the cover 2-13 is provided with an annular sealing rib 2-18 corresponding to the annular sealing groove 2-17, and the annular sealing rib 2-18 extends at least partially into the annular sealing groove 2-17 and elastically abuts against the sealing strip 2-102.

[0097] Preferably, the radial cross-section of the sealing strip 2-102 is circular, the diameter of the sealing strip 2-102 is greater than or equal to the groove width of the annular sealing groove 2-17, the distance between the annular sealing rib 2-18 and the bottom of the annular sealing groove 2-17 is less than the diameter of the sealing strip 2-102, and the annular sealing rib 2-18 compresses the sealing strip 2-102 to ensure sealing.

[0098] In this embodiment, the cover 2-13 can be detachably installed on the outer wall of the drying duct in any possible way. Preferably, the cover 2-13 is connected to the outer wall of the drying duct with screws.

[0099] Specifically, the cover 2-13 is provided with at least two ear plates arranged at intervals on its periphery, and the outer wall of the drying air duct is provided with screw posts corresponding to the ear plates on the periphery of the cover 2-13. The ends of the ear plates abut against the screw posts, and the cover 2-13 is fixed to the drying air duct by screws that pass through the ear plates and are tightened on the screw posts.

[0100] Preferably, in this embodiment, the middle part of the cover 2-13 is provided with a groove protruding into the drying air duct, the end face of the groove is coplanar with the inner sidewall of the drying air duct, and the circumferential surface of the groove fits against the inner wall of the maintenance opening 2-101.

[0101] Preferred, such as Figure 12 As shown in this embodiment, a wind baffle 2-131 is provided on the end face of the grooved molding. The wind baffle 2-131 is provided on the upstream side of the heater 2-12 along the airflow direction, extends along the length direction of the heater 2-12, and is spaced apart from the heater 2-12 to block the gap between the heater 2-12 and the end face of the grooved molding.

[0102] Specifically, the cover 2-13 is arranged parallel to the side of the heater 2-12, with a gap between them. The baffle rib 2-131 is located upstream of the heater 2-12, parallel to its length, and spaced apart from it. The baffle rib 2-131 reduces the amount of drying airflow passing between the heater 2-12 and the cover 2-13, lowering the flow velocity of the drying airflow passing through the gap between them. This improves the accuracy of the temperature measured at the cover 2-13, ensuring that the temperature of the cover 2-13 accurately reflects the condition of the heater 2-12, thus enhancing safety.

[0103] In some specific examples, a drying filter device 2-11 is provided in the drying air duct. The drying filter device 2-11 is located in the drying air duct upstream of the heater 2-12 along the airflow direction and is spaced apart from the heater 2-12. It is used to filter the drying airflow and reduce the accumulation of lint on the heater 2-12.

[0104] In this embodiment, the drying and filtering device 2-11 includes a support frame 2-111 and a drying filter screen disposed on the support frame 2-111. The support frame 2-111 has a hollow center, and the drying filter screen covers the hollow center of the support frame 2-111. The periphery of the support frame 2-111 is connected to the inner wall of the drying air duct, so that the airflow passes through the drying filter screen and ensures the filtration effect.

[0105] like Figure 13 As shown, in this embodiment, the support frame 2-111 has a certain width along the airflow direction, and the drying filter is disposed on the side of the support frame 2-111 near the heater 2-12. The drying filter and the support frame 2-111 form a groove with the opening facing upstream in the airflow direction. This allows the drying filter device 2-11 to accommodate more lint, reducing the cleaning frequency, and also facilitates the cleaning of lint from the drying filter device 2-11, improving cleaning efficiency.

[0106] Preferably, in this embodiment, a flow divider 2-107 is also provided in the drying air duct upstream of the drying filter device 2-11. The flow divider 2-107 is spaced in multiples and is used to divide the airflow upstream of the drying filter device 2-11 so that the drying airflow flows evenly through the drying filter device 2-11 and the heater 2-12.

[0107] In some specific embodiments, the drying device 2 includes a drying module 2-1, a fan module 2-2, and a condenser module 2-3. The fan module 2-2 is disposed between the drying module 2-1 and the condenser module 2-3. The air outlet of the drying module 2-1 is connected to the air inlet of the cylinder module, and the air inlet of the drying module 2-1 is connected to the air outlet of the fan module 2-2. The air inlet of the fan module 2-2 is connected to the air outlet of the condenser module 2-3, and the air inlet of the condenser module 2-3 is connected to the air outlet of the cylinder module. A heater 2-12 is installed inside the drying duct and is capable of heating the airflow passing through the heater 2-12.

[0108] In some specific examples, the main body of the heater 2-12 is a rectangular structure, and the heater 2-12 is inclined relative to the drying air duct along its length. Exemplarily, the heater 2-12 of the present invention is a PTC heater 2-12, with its rear end inclined to the left. It should be noted that the type of heater 2-12 is not limited to the aforementioned PTC heater 2-12; those skilled in the art can flexibly set the specific type of heater 2-12 according to specific circumstances.

[0109] Preferably, in this embodiment, the drying device 2 is disposed on the top side of the cylinder module, the drying air duct is configured to be flat and extends along the axial direction of the cylinder module, and the maintenance opening is disposed on the top of the drying air duct.

[0110] like Figure 10 As shown, in some specific embodiments, the drying duct of the present invention includes a first duct 2-104, a second duct 2-105, and a third duct 2-106 connected in sequence. The first duct 2-104 and the second duct 2-105 both extend horizontally and are perpendicular to each other. The third duct 2-106 extends downwards. The rear end of the first duct 2-104 forms the air inlet of the drying duct, and the bottom end of the third duct 2-106 forms the air outlet of the drying duct. A heater 2-12 is installed inside the second duct 2-105 and extends horizontally in the front-to-back direction. The front end of the heater 2-12 is located near the end of the second duct 2-105 connected to the first duct 2-104, and the rear end of the heater 2-12 is located near the end of the second duct 2-105 connected to the third duct 2-106.

[0111] For example, the first air duct 2-104 extends horizontally in the front-back direction, the second air duct 2-105 extends horizontally in the left-right direction, and the third air duct 2-106 extends downward at an angle. The front end of the first air duct 2-104 is connected to the right end of the second air duct 2-105, the left end of the second air duct 2-105 is connected to the top end of the third air duct 2-106, the heater 2-12 is located inside the second air duct 2-105, extends horizontally in the front-back direction, and the rear end of the heater 2-12 is inclined to the left.

[0112] like Figure 9 As shown, the maintenance opening corresponds to the second air duct and is located at the top of the second air duct. Specifically, the maintenance opening corresponds to the heater inside the second air duct.

[0113] like Figure 10 In this embodiment, the diversion ribs 2-107 are disposed within the first air duct 2-104, and a plurality of them are arranged along the width direction of the first air duct 2-104. Each diversion rib 2-107 is parallel to each other, and the front end of each diversion rib 2-107 bends and extends toward the drying filter device 2-11.

[0114] Preferably, in this embodiment, a plurality of spaced auxiliary diversion ribs 2-107 are also provided at the angle between the drying and filtering device 2-11 and the heater 2-12.

[0115] Preferably, the drying filter device 2-11 is removable and installed inside the drying air duct.

[0116] Specifically, this invention features a first pull-out opening on the drying duct, through which a portion of the drying filter device 2-11 extends into the drying duct. In other words, the drying filter device 2-11 is connected to the drying duct via a plug-in connection. When the user needs to clean the drying filter device 2-11, they simply pull it out of the drying duct. After cleaning, the drying filter device 2-11 is reinserted into the drying duct through the first pull-out opening. This convenient operation provides a better user experience.

[0117] Preferably, the housing 1 of the garment processing device of the present invention is provided with a second pull-out port at a position corresponding to the first pull-out port, and a part of the drying filter device 2-11 extends into the drying air duct through the second pull-out port and the first pull-out port in sequence.

[0118] The present invention places the second pull-out opening on the control panel of the housing 1. Exemplarily, the second pull-out opening is located in the upper right corner of the control panel. Preferably, the drying system of the present invention further includes an annular sealing member installed within the first pull-out opening, and a portion of the drying filter device 2-11 extends through the annular sealing member into the drying air duct.

[0119] In some specific examples, the upper and lower walls of the drying duct are provided with guide rails for installing the drying filter device 2-11, and the drying filter device can be pulled back and forth along the guide rails.

[0120] In this embodiment, the guide rail includes a first guide groove disposed on the upper and lower walls of the drying duct. The width of the first guide groove is adapted to the width of the support frame 2-111. The upper and lower sides of the support frame 2-111 are respectively slidably disposed within the first guide grooves on the upper and lower walls of the drying duct. The upper and lower ends of the support frame 2-111 are also provided with a second guide groove 2-112 parallel to the extending direction of the first guide groove. A guide ridge is disposed within the first guide groove, extending into the second guide groove 2-112. By providing the first guide groove that limits the upper and lower sides of the support frame 2-111, and by providing the mutually cooperating guide ridge and second guide groove 2-112 between the first guide groove and the support frame 2-111, the smoothness of the drying filter device 2-11's retraction can be ensured. Simultaneously, the amount of drying airflow passing between the support frame 2-111 and the inner wall of the drying duct can be reduced, preventing lint from accumulating at the guide rail.

[0121] In some specific examples, the drying duct includes a first housing and a second housing that are interlocked. One of the first housing and the second housing is provided with a housing sealing groove, and a sealing ring is provided in the housing sealing groove. The other of the first housing and the second housing is provided with a housing sealing rib. When the first housing and the second housing are interlocked, the housing sealing rib is inserted into the housing sealing groove, and the housing sealing rib is squeezed to achieve a seal.

[0122] Preferably, in this embodiment, a control method for a garment processing device is also provided, wherein the garment processing device is equipped with the aforementioned drying device 2. The control method includes:

[0123] S1: Obtain the temperature of capping 2-13;

[0124] S2: If the temperature of the cover 2-13 is greater than or equal to the preset temperature, the drying device 2 will stop operating and trigger an alarm.

[0125] The above settings can prevent the shavings from igniting during the drying process due to excessive accumulation of shavings in heaters 2-12.

[0126] Preferably, in this embodiment, the control method of the clothing handling device further includes:

[0127] S3: After cleaning the drying and filtering device 2-11, calculate the drying efficiency of the drying device 2;

[0128] S4: If the drying efficiency drops to the preset value, remind the user to clean heaters 2-12.

[0129] In this embodiment, when the drying efficiency of the drying device 2 is detected to be reduced, it only reminds the user to clean the lint inside the heater 2-12, without interrupting the drying process.

[0130] When the temperature of the sealing cap 2-13 is detected to be greater than or equal to the preset temperature, the drying process is immediately interrupted, or the power supply to the heater 2-12 is stopped, and the airflow flowing through the condenser is used to cool the heater 2-12 to avoid danger.

[0131] In this embodiment, the drying efficiency can be calculated based on the drying time and the weight change of the load inside the garment processing equipment before and after drying.

[0132] Example 2

[0133] In this embodiment of the invention, a clothing processing device is described, including a housing 1, a cylindrical module installed inside the housing 1, and a drying device 2 disposed inside the housing 1 and communicating with the cylindrical module. The drying device 2 is used to dry the clothing inside the cylindrical module.

[0134] The drying device 2 includes at least a drying module 2-1 and a fan module 2-2. The drying module 2-1 includes a drying air duct, a heater 2-12 and a drying filter device 2-11 installed in the drying air duct. The upper and lower walls of the drying air duct are provided with guide rails for installing the drying filter device 2-11. The drying filter device can be pulled back and forth along the guide rails. The air entering the drying module 2-1 is filtered by the drying filter device 2-11 and heated by the heater 2-12 before entering the drum module for holding clothes to dry the clothes.

[0135] The front end of the drying and filtering device 2-11 is connected to an end plate, which is embedded in the front side wall of the housing 1 of the clothing processing equipment. The user can pull the drying and filtering device 2-11 through the end plate. The end plate can be equipped with a handle or other structure to facilitate pulling.

[0136] During assembly, if there is an error in the installation of the drying device 2, especially if there is an error in the installation position between the front end of the drying device 2 and the housing 1, the end plate may not be able to fit into the front side wall of the housing 1. In this case, the drying filter device 2-11 may not be able to be fully inserted into the drying air duct. Alternatively, even if the end plate can fit into the front side wall of the housing 1, the interference force between the end plate and the front side wall of the housing 1 will increase the assembly gap between the drying filter device 2-11 and the drying air duct, thereby causing problems such as poor appearance and low filtration effect.

[0137] This embodiment mainly provides an installation structure between the drying device 2 and the housing 1, which is used to solve the problem of poor fit accuracy between the end plate of the filter device in the drying device 2 and other external parts caused by installation errors in the prior art.

[0138] like Figures 1 to 7As shown in the embodiment of the present invention, a clothing processing device is introduced, including a box 1, a drum module installed in the box 1, and a drying device 2 installed in the box 1 and connected to the drum module. The drying device 2 is fixed in the box 1 and its two ends are connected to the drum module for drying the clothing in the drum module.

[0139] In this embodiment, the drying device 2 is installed in the space between the housing 1 and the drum module, specifically, as follows: Figure 1 and Figure 4 As shown, the drying device 2 is installed on the top side inside the housing 1. The installation structure of the drying device 2 includes a pre-installation structure and a fastening structure. The pre-installation structure includes a plug-in structure 6 between the first end of the drying device 2 and the rear side of the housing 1, and a snap-fit ​​structure between the second end of the drying device 2 and the front side of the housing 1, for pre-installing and positioning the drying device 2. The fastening structure includes a screw structure for locking the relative position between the pre-installed and positioned drying device 2 and the housing 1.

[0140] In this embodiment, the drying device 2 is pre-installed using the plug-in structure 6 and the snap-fit ​​structure, and then the relative position between the drying device 2 and the housing 1 is locked using the fastening structure. This improves the installation accuracy of the drying device 2, thereby improving the fit accuracy between the end plate of the drying filter device 2-11 of the drying device 2 and other appearance parts. This avoids the problem of increased gap between the filter device and the drying channel and low appearance refinement of the clothing processing equipment caused by mutual interference between the end plate of the drying filter device 2-11 of the drying device 2 and other appearance parts. This improves the working stability and appearance effect of the clothing processing equipment.

[0141] Specifically, the pre-installed structure includes a plug-in structure 6 and a snap-fit ​​structure, wherein the snap-fit ​​direction of the snap-fit ​​structure is perpendicular to the plug-in direction of the plug-in structure 6.

[0142] The snap-fit ​​structure includes a first snap-fit ​​part disposed at the top of the second end of the drying device, and a second snap-fit ​​part disposed on the housing and snap-fitted with the first snap-fit ​​part.

[0143] Specifically, the first and second locking parts are respectively a locking claw and a locking slot corresponding to the locking claw, with the locking claw locking into the locking slot; preferably, the locking claw is set at the top of the second end of the drying device, and the locking slot is set on the mounting beam.

[0144] like Figure 1 , Figure 2 and Figure 4As shown, in some specific examples, the front top of the housing 1 is provided with a mounting beam 1-2 corresponding to the second end of the drying device 2. The snap-fit ​​structure includes a claw 3 set on the top of the second end of the drying device 2 and a slot set on the mounting beam 1-2. The claw 3 snaps into the slot to position the second end of the drying device 2.

[0145] During installation, first connect the first end of the drying device 2 to the plug-in structure 6 on the rear side of the box 1. Then, move the second end of the drying device 2 upward and engage the claw 3 in the slot on the mounting beam 1-2 at the top front end of the box 1 to pre-install and position the drying device 2.

[0146] In this embodiment, the claw 3 includes a neck extending vertically upward from the top of the second end of the drying device 2, and a claw portion located at the end of the neck and protruding to one side of the neck; after the claw 3 passes through the slot, it is fastened to the mounting beam 1-2 by the claw portion.

[0147] In some possible embodiments, to ensure that the plug-in structure 6 and the snap-fit ​​structure do not interfere with each other, the extension direction of the claw is set to be perpendicular to the plug-in direction of the plug-in structure 6. Specifically, the plug-in structure 6 between the first end of the drying device 2 and the rear side wall of the housing 1 is plugged in from a first direction, and the snap-fit ​​structure between the second end of the drying device 2 and the front crossbeam of the housing 1 is snapped in from a second direction. The first direction and the second direction are perpendicular, thereby preventing the plug-in structure 6 between the drying device 2 and the rear side wall of the housing 1 from becoming loose during the installation of the snap-fit ​​structure. At the same time, the snap-fit ​​structure can also limit the position of the drying device 2 along the first direction, improving the installation stability of the drying device 2.

[0148] In this embodiment, the second direction is the direction of movement of the claw 3 after it is inserted into the bayonet slot, that is, the direction of extension of the claw portion of the claw 3 relative to the neck.

[0149] Preferably, in this embodiment, the first direction is the front-to-back direction of the box 1, and the second direction is the left-to-right direction of the box 1. The first end of the drying device 2 is installed on the rear side wall of the box 1, and the second end of the drying device 2 corresponds to the front side of the box 1.

[0150] like Figure 2 and Figure 7As shown, in some other possible embodiments, a positioning structure is also provided between the second end of the drying device 2 and the mounting beam 1-2. The positioning structure includes a snap-fit ​​post extending vertically upward from the top of the second end of the drying device 2, and a first positioning port that engages with the snap-fit ​​post. During the process of the claw 3 snapping into the port, at least part of the upper end of the snap-fit ​​post is inserted into the first positioning port to prevent the claw 3 from disengaging from the port. That is, the drying device can be relatively stably maintained within the chamber through the insertion structure, snap-fit ​​structure, and positioning structure, and installation accuracy can be guaranteed.

[0151] Specifically, the positioning structure can be set separately or as part of the fastening structure.

[0152] In this embodiment, the fastening structure includes a first screw structure disposed between the second end of the drying device 2 and the mounting beam 1-2. This structure includes a first screw post 4 extending vertically upward from the top of the second end of the drying device 2, and a first positioning port disposed on the mounting beam 1-2 for engaging with the first screw post 4. During the process of the claw 3 engaging the positioning port, at least part of the upper end of the first screw post 4 is inserted into the first positioning port to prevent the claw 3 from disengaging from the positioning port. The engaging post is the first screw post 4.

[0153] Specifically, in this embodiment, after the first end of the drying device 2 is inserted into the insertion structure 6 between the first end and the rear side wall of the box 1, the second end of the drying device 2 is pushed upward so that the first screw post 4 is aligned with the first positioning port and inserted. At the same time, the claw 3 undergoes elastic deformation and then springs back to lock in the slot.

[0154] The claw 3 can limit the vertical displacement of the second end of the drying device 2. The first screw post 4 limits the horizontal position of the second end of the drying device 2 by limiting the first positioning port. The snap-fit ​​structure cooperates with the first screw structure to achieve precise positioning between the second end of the drying device 2 and the box 1. At the same time, the setting of the first screw structure can prevent the claw 3 from disengaging from the snap-fit ​​port, ensuring the stability of the positioning of the second end of the drying device 2.

[0155] Preferably, in this embodiment, the top of the claw 3 is provided with a slope that is inclined downward along the extension direction of the claw. During the process of the claw 3 engaging with the slot, the slope at the top of the claw 3 abuts and slides against the side of the slot, which can improve the smoothness of the claw 3 engaging.

[0156] The first screw structure also includes a first screw that mates with the first screw post 4. The first screw is tightened inside the first screw post 4 to reinforce the connection structure between the first screw post 4 and the mounting beam 1-2.

[0157] Preferably, in this embodiment, the first positioning port and the bayonet are spaced apart along the length of the mounting beam 1-2, and the first screw structure is preferably located on the side opposite to the direction of the claw portion of the claw 3.

[0158] In this embodiment, the housing 1 is rectangular in shape, the axis of the cylindrical module extends along the front-to-back direction, and the opening of the cylindrical module corresponds to the clothing loading port on the front side wall of the housing 1. The drying device 2 is installed on the top side of the cylindrical module. By setting the drying device 2 to extend along the front-to-back direction and to be located on the top side of the cylindrical module, the space occupied at the corner of the cylindrical module and the rectangular housing 1 can be utilized, thus improving the utilization rate of the internal space of the housing 1.

[0159] In some specific embodiments, the sidewalls of the housing 1 include a front sidewall, a rear sidewall, and left and right sidewalls. The mounting beam 1-2 is a long strip plate that extends along the left and right direction of the housing 1. The two ends of the mounting beam 1-2 overlap the top of the front end of the left and right sidewalls respectively and are fixedly connected to the left and right sidewalls of the housing 1.

[0160] The claw 3 extends vertically upward from the top of the second end of the drying device 2. The claw portion of the claw 3 protrudes from the left or right side of the neck and is used to limit the movement of the mounting beam 1-2. Specifically, after the claw 3 passes through the bayonet, it is hung on the mounting beam 1-2 by the claw portion of the claw 3 to achieve the vertical positioning of the second end of the drying device 2. The neck of the claw 3 limits the front and rear sides of the bayonet to achieve the front and rear positioning of the second end of the drying device 2.

[0161] Preferably, in this embodiment, the front and rear sides of the claw 3 are provided with first reinforcing ribs, which are disposed between the front and rear sides of the neck of the claw 3 and the top of the second end of the drying device 2.

[0162] Preferably, in some possible embodiments, the vertical distance between the top of the first reinforcing rib and the claw of the claw 3 is equal to the thickness of the mounting beam 1-2 at the latch, and the mounting beam 1-2 at the latch is clamped between the claw and the first reinforcing rib to improve the positioning effect on the second end of the drying device 2.

[0163] like Figure 4 and Figure 5As shown, in this embodiment, the plug-in structure 6 includes a plug-in post 6-2 disposed at the first end of the drying device 2 and a bracket 6-1 mounted on the rear side wall of the housing 1. The bracket 6-1 includes a first side wall 6-11 connected to the rear side wall of the housing 1 and a second side wall 6-12 disposed opposite to the first side wall 6-11. The plug-in post 6-2 is disposed at the first end of the drying device 2 and extends from the first end of the drying device 2 toward the rear side of the housing 1. The second side wall 6-12 of the bracket 6-1 is provided with a plug-in hole, and the plug-in post 6-2 is inserted into the plug-in hole.

[0164] Specifically, the first sidewall 6-11 and the second sidewall 6-12 of the bracket 6-1 are spaced apart, and the first sidewall 6-11 is fixedly connected to the inner side of the rear sidewall of the housing 1 by screws. The first end of the drying device 2 is provided with at least two parallel insertion posts 6-2, and the second sidewall 6-12 of the bracket 6-1 is provided with insertion holes corresponding to the insertion posts 6-2.

[0165] Preferably, in this embodiment, the bracket 6-1 is U-shaped and further includes a third sidewall 6-13 connected between the first sidewall 6-11 and the second sidewall 6-12.

[0166] Preferably, in this embodiment, a buffer is provided inside the insertion hole. The buffer is made of an elastic material, preferably rubber. The insertion post 6-2 abuts against the bracket 6-1 through the buffer. The buffer is disposed inside the insertion hole and includes a first buffer portion that fits against the inner wall of the insertion hole, and a second buffer portion and a third buffer portion disposed at both ends of the first buffer portion and extending radially outward along the first buffer portion. The second buffer portion and the third buffer portion respectively limit and abut against the two sides of the second sidewall 6-12, thereby holding the buffer on the second sidewall 6-12 of the bracket 6-1.

[0167] Preferably, the first buffer part, the second buffer part, and the third buffer part are a single piece.

[0168] Preferably, the inner diameter of the first buffer part is the same as the diameter of the plug post 6-2.

[0169] In this embodiment, by setting a buffer, a buffer connection is achieved between the first end of the drying device 2 and the support 6-1. The buffer can reduce the impact of factors such as deformation of the box 1 or installation error on the positioning accuracy between the second end of the drying device 2 and the box 1.

[0170] Preferably, in some specific embodiments, a first mounting hole is provided on the first sidewall 6-11 of the bracket 6-1, and the first mounting hole protrudes from the side of the first sidewall 6-11 away from the second sidewall 6-12 to form a protruding end; a second mounting hole is provided on the rear sidewall of the housing 1 to mate with the protruding end, and the protruding end is inserted into the second mounting hole. By providing a protruding end on the first sidewall 6-11 of the bracket 6-1 and a second mounting hole on the rear sidewall of the housing 1, the protruding end of the bracket 6-1 is inserted into the second mounting hole during installation, thereby achieving pre-positioning of the bracket 6-1. Then, the bracket 6-1 is fixed to the rear sidewall of the housing 1 by a screw structure, which can ensure the positioning effect and installation accuracy of the bracket 6-1.

[0171] In some specific embodiments, such as Figure 5 As shown, a positioning post 6-3 is also provided on the first end of the drying device 2.

By providing the positioning post 6-3 and the positioning holes, a reference can be provided for the installation angle of the first end of the drying device 2, thereby improving the installation efficiency of the drying device 2.

[0172] In some possible embodiments, the insertion post 6-2 and the positioning post 6-3 are disposed on the top of the end face of the first end of the drying device 2. A second reinforcing rib extending radially along the insertion post 6-2 and the positioning post 6-3 is provided between the root periphery of the insertion post 6-2 and the end face of the first end of the drying device 2 to improve the strength of the insertion post 6-2 and the positioning post 6-3.

Screws adapted to the screw posts pass through the first and second mounting holes and are installed inside the screw posts. By setting the connecting plate 5, the installation of the middle part of the drying device 2 can be reinforced, improving the positioning effect of the middle part of the drying device 2. This prevents the connection structure between the drying module 2-1 and the fan module 2-2 from loosening due to vibration during use, thus reducing the assembly accuracy between the drying device 2 and the housing 1 and improving the working stability of the clothing processing equipment.

[0186] Preferred, such as Figure 6 As shown in this embodiment, a pressing form is provided between the first plate portion 5-1 and the third plate portion 5-3 and / or between the second plate portion 5-2 and the third plate portion 5-3 on the connecting plate 5 to enhance the overall strength of the connecting plate 5.

[0187] In some preferred embodiments, mounting longitudinal beams 1-3 extending along the front-rear direction of the box body 1 are provided on the top of the left and right side walls. Specifically, the top of the left and right side walls and the top of the rear side wall of the box body 1 are provided with folded edges extending horizontally inward towards the inside of the box body 1. The mounting longitudinal beams 1-3 are located on the top of the left and right side walls of the box body 1 and are attached to the folded edges on the top of the left and right side walls of the box body 1. The side of the mounting longitudinal beams 1-3 corresponding to the end of the folded edge away from the side wall of the box body 1 is bent vertically downward. The third plate portion 5-3 is attached to the side of the mounting longitudinal beams 1-3 that extends vertically downward.

[0188] Preferably, the front end of the mounting longitudinal beam 1-3 extends to be flush with the front ends of the left and right side walls of the housing 1, the left and right ends of the mounting crossbeam 1-2 rest on the front ends of the mounting longitudinal beam 1-3, and the rear end of the mounting longitudinal beam 1-3 extends to be flush with the rear ends of the left and right side walls of the housing 1, and extends towards the folded edge at the top of the rear side wall of the housing 1 to enhance the overall strength of the housing 1. The mounting longitudinal beam 1-3, the mounting crossbeam 1-2, and the folded edge are connected by screws.

[0189] The drying module 2-1 is equipped with a drying filter device 2-11, which is installed inside the drying module 2-1 via a guide rail. The drying airflow in the drying device 2-1 flows through the drying filter device 2-11 and the heater 2-12 in the drying module 2-1 before entering the cylindrical module. A main control board 1-1 is installed on the top front side of the housing 1. The drying filter device 2-11 is pulled out from the middle of the main control board 1-1, and an end plate connected to the drying filter device 2-11 and used for pulling out the drying filter device 2-11 is embedded in the main control board 1-1.

[0190] The fastening structure also includes a second screw structure between the two sides of the pull-out opening on the drying device 2 and the main control board 1-1.

[0191] In this embodiment, the main control board 1-1 is provided with an embedding groove for accommodating the end plate of the drying and filtering device 2-11. When the drying and filtering device 2-11 is pushed into the drying module 2-1, the end plate is embedded in the embedding groove, and the front end of the end plate is coplanar with the front end of the main control board 1-1 to ensure the appearance effect.

[0192] A second screw post is provided on the end face of the second end of the drying device 2. Preferably, a second positioning port is provided on the bottom of the mounting groove. A screw adapted to the second screw post passes through the second positioning port and is tightened on the second screw post to lock the relative position between the drying module 2-1 and the main control board 1-1, thereby preventing the pull-out port on the drying module 2-1 from shifting from the pull-out port on the main control board 1-1, so as to ensure the smoothness of pulling out the drying filter device 2-11 and the fitting effect between the end plate and the main control board 1-1.

[0193] Preferably, in this embodiment, the front sidewall of the housing 1 is formed by splicing a main control board 1-1 and a front panel. The main control board 1-1 is connected to the top of the front panel, the lower end of the main control board 1-1 is screwed to the front panel, and the upper end of the main control board 1-1 is screwed to the mounting beam 1-2.

[0194] Specifically, the main control board 1-1 has a rearwardly extending extension plate on its rear side. The extension plate is attached to the top of the mounting beam 1-2 and is connected to the mounting beam 1-2 by screws. The extension plate has multiple extension plates arranged at intervals along the length direction of the main control board 1-1.

[0195] Preferably, in this embodiment, the drying device 2 further includes a condenser module 2-3 disposed at the air inlet end of the fan module 2-2. The condenser module 2-3 is equipped with a condenser filter and a cleaning module for self-cleaning the condenser filter. By providing a condenser filter in the condenser module 2-3, dual filtration of the drying airflow can be achieved, improving the filtration effect of the drying airflow. At the same time, by providing a cleaning module for self-cleaning the condenser filter, automatic cleaning of the condenser filter can be achieved, and the cleaning frequency of the drying filter 2-11 can be reduced, improving the user experience.

[0196] Preferably, in this embodiment, the condensation filtration device includes a filter support 6-1 and a filter screen disposed on the filter support 6-1; the filter support 6-1 is arranged around the filter screen, and a spray water path is provided in at least one side of the filter screen, with a spray nozzle provided on the side of the spray water path closest to the filter screen; and / or, it also includes a cleaning brush and a drive module for driving the cleaning brush, the drive module driving the cleaning brush to clean the lint on the filter screen.

[0197] Example 3

[0198] like Figures 14 to 18 As shown in the figure, this embodiment introduces a drying device. This embodiment mainly describes the condensation module in the above embodiments one and two.

[0199] Specifically, the condensation module includes a condensation duct 2-31 and a condensation filter device 2-36 disposed within the condensation duct 2-31.

[0200] like Figures 15-16 As shown, in this embodiment, the condenser filter 2-36 covers the entire cross-section of the condenser duct 2-31, so that the circulating airflow in the condenser duct 2-31 completely flows through the filter screen 2-361, ensuring the filtration effect inside the condenser duct 2-31.

[0201] Specifically, a spray water path 2-363 is provided at the upper end of the condensation filter device 2-36. The two ends of the spray water path 2-363 in the length direction pass through the matching notches provided on the wall of the condensation air duct 2-31, so that the condensation filter device 2-36 is stably installed in the condensation air duct 2-31.

[0202] Preferably, in some specific embodiments, the condensation filter device 2-36 is generally rhomboid in shape, so that the spray water path 2-363 in the condensation filter device 2-36 has a certain tilt angle, which can guide the water flow, make the water flow speed faster, and improve the efficiency of cleaning the filter screen.

[0203] like Figure 16 As shown, in this embodiment, the condensation filter device 2-36 includes a filter support 2-362 and a filter 2-361 disposed on the filter support 2-362. The filter 2-361 is detachably installed in the air duct. The filter support 2-362 is arranged around the filter 2-361. A spray water path 2-363 is provided in the filter support 2-362 located above the filter 2-361. The spray water path 2-363 extends along the length direction of the condensation filter device 2-3601.

[0204] Specifically, the filter support 2-362 includes a support body and a spray water channel cover 2-366. The support body is used to support the filter screen 2-361. The top of the filter support 2-362 is provided with a groove, and the spray water channel cover 2-366 is fastened to the groove of the water channel, forming a spray water channel 2-363 between the cover and the support body.

[0205] Preferably, the spray water channel cover 2-366 and the filter screen bracket 2-362 are connected by fusion bonding to ensure the sealing of the spray water channel 2-363 and improve the cleaning efficiency of the filter screen 2-361.

[0206] like Figure 17 As shown in this embodiment, the spray water path 2-363 is provided with water-blocking ribs 2-3634. The water-blocking ribs 2-3634 are set at different positions to form water inlet water path 2-3631 and water outlet water path 2-3632, which are connected and arranged in parallel. Both water inlet water path 2-3631 and water outlet water path 2-3632 extend along the length direction of the condensation filter device 2-36.

[0207] Preferably, the length of the water outlet path 2-3632 extending along the length of the condensation filter device 2-36 is greater than or equal to the length of the filter screen 2-361, so that the water flow passes fully through the filter screen 2-361, thereby improving the cleaning efficiency of the filter screen 2-361.

[0208] In a further preferred embodiment, the different positions of the water-blocking ribs 2-3634 inside the spray water path 2-363 also form a drainage water path 2-3633 to prevent excessive water flow and pressure from damaging the spray water path 2-363; the inlet water path 2-3631 and the drainage water path 2-3633 are interconnected and arranged side by side through the outlet water path 2-3632; the drainage water path 2-3633 extends along the length of the condensation filter device 2-36, and the inlet water path 2-3631 and the drainage water path 2-3633 are on the same side of the outlet water path 2-3632.

[0209] Furthermore, in this embodiment, the spray water path 2-363 also includes a first connecting port 2-3635 and a second connecting port 2-3636. The inlet water path 2-3631 is connected to the outlet water path 2-3632 through the first connecting port 2-3635, and the outlet water path 2-3633 is connected to the outlet water path 2-3632 through the second connecting port 2-3636. The first connecting port 2-3635 and the second connecting port 2-3636 correspond to the middle part of the outlet water path 2-3632 respectively, and divide the outlet water path 2-3632 into three sections.

[0210] like Figures 16 to 18 As shown in this embodiment, the water inlet 2-364 is provided in the water inlet channel 2-3631. The water inlet 2-364 is located at the bottom of the spray water channel 2-363, bends downward and extends to connect with the water inlet end, so as to provide water flow for cleaning the filter screen.

[0211] Preferably, a drain outlet 2-365 is provided at the end of the water inlet channel 2-3631 away from the water inlet 2-364. The drain outlet 2-365 is located at the bottom of the drain channel 2-3633 and is connected to the drain channel 2-34 to drain excess water. The water flows into the drain channel 2-34 through the drain outlet 2-365 and is discharged through the drain channel 2-34.

[0212] In this embodiment, a plurality of guide ribs 2-341 are arranged in an alternating pattern on two opposite side walls inside the drainage channel. The guide ribs 2-341 extend downward at an angle from the inner wall of the drainage channel to increase the travel distance of the water flow within the drainage channel and to condense the drying airflow.

[0213] like Figure 16As shown, in this embodiment, a first spray port 2-367 is provided on the side of the water outlet 6031 in the spray water path 2-363 near the filter screen 2-361. The first spray port 2-367 is located at the corresponding position of the water outlet 6031 and the filter screen 2-361.

[0214] Specifically, multiple first spray nozzles 2-367 are provided and are located directly above the filter screen 2-361, corresponding to the upstream side of the filter screen 2-361 near the airflow direction; the opening area of ​​the water inlet side of the first spray nozzle 2-367 is larger than the opening area of ​​the water outlet side, which can increase the spraying force of the water flow on the filter screen 2-361 and avoid insufficient water pressure leading to poor rinsing effect on the filter screen 2-361, thus affecting the user experience.

[0215] Furthermore, multiple first spray nozzles 2-367 are arranged along the length of the condensation filter device 2-36. The arrangement density of the first spray nozzles 2-367 on the water outlet channels 2-3632 on both sides of the first connecting port 2-3635 and the second connecting port 2-3636 is greater than or equal to the arrangement density of the first spray nozzles 2-367 on the water outlet channel 2-3632 between the first connecting port 2-3635 and the second connecting port 2-3636. This can control the water pressure and flow rate of the water flow rinsing the filter screen 2-361, preventing the filter screen 2-361 from being washed away due to excessive water pressure on both sides of the first spray nozzles 2-367 on both sides of the first connecting port 2-3635 and the second connecting port 2-3636, thus improving the user experience.

[0216] Water flows into the inlet water passage 2-3631 from the inlet 2-364, passes through the first connecting port 2-3635, and reaches the outlet water passage 2-3632. The filter screen 2-361 is fully sprayed through the first spray port 2-367 of the outlet water passage 2-3632. When there is excess water, the excess water flows into the drain water passage 2-3633 through the second connecting port 2-3636, and flows out through the drain port 2-365 set on the drain water passage 2-3633. This can prevent excessive water pressure from damaging the water passage and increase the service life of the condensation filter device 2-36.

[0217] like Figures 16 to 18 As shown in this embodiment, the filter support 2-362 is also provided with a support rib 2-3621 to support the filter screen 2-361. One end of the support rib 2-3621 is connected to the bottom of the spray water channel 2-363, and the other end extends along the width direction of the condensation filter device 2-36 to the bottom of the condensation filter device 2-36.

[0218] Specifically, there are two support ribs 2-3621, which correspond to the connection points at the bottom of the spray water path 2-363 and the first connecting port 2-3635 and the second connecting port 2-3636, respectively. The support ribs 2-3621 divide the filter screen 2-361 into three groups, so that each group of filter screens 2-361 corresponds to a section of water outlet 2-3632 set above it, which strengthens the stability of the filter screen 601. At the same time, it allows the water flow to fully correspond to the filter screen 2-361, spray the filter screen 2-361 fully, and improve the self-cleaning effect of the condensation filter device 2-36.

[0219] In this embodiment, the spray water path 2-363 further includes a second spray port 2-3661. The second spray port 2-3661 is disposed on the spray water path cover 2-366 and faces the spray water path 2-363 towards the upstream side near the airflow direction. It is used to rinse the upper housing of the air duct and thoroughly clean the residual lint in the condensation air duct 2-31, making the condensation filter device 2-36 work more efficiently.

[0220] Specifically, the second spray nozzle 2-3661 is in the shape of a round hole and is located above the first spray nozzle 2-367. It has multiple nozzles arranged along the length of the condensation filter device 2-36.

[0221] Preferably, the second spray nozzles 2-3661 are arranged at the same intervals along the length of the condensation filter device 2-36.

[0222] Water flows into the inlet water passage 2-3631 through the inlet, then through the first connecting port 2-3635 to the outlet water passage 2-3632. The water first flows out from the first spray port 2-367. When the water in the outlet water passage 607 accumulates to a certain height, it then sprays the filter screen 2-361 near the upstream side of the airflow direction in the condenser duct 2-31 through the second spray port 2-3661. This can clean the lint carried in the circulating air on the upstream side of the filter screen 2-361 near the airflow direction in the condenser duct 2-31, as well as the lint accumulated on the side of the upper shell of the duct located inside the condenser duct 2-31. This avoids the filtration effect being affected by the accumulation of lint on the inner wall of the condenser duct 2-31, and improves the cleaning effect of the condenser filter device 2-36.

[0223] like Figure 15 As shown, in this embodiment, the bottom of the lower housing 2-311 of the air duct is provided with a lower outlet 2-35 that communicates with the condenser air duct 2-31, and the lower outlet 2-35 is located below the air inlet 2-321.

[0224] Specifically, the lower discharge port 2-35 is located at the bottom of the vertical air duct 2-32 to discharge clean wastewater and excess water.

[0225] Wastewater from the first spray nozzle 2-367 and the second spray nozzle 2-3661 on the spray water path 2-363, after rinsing and cleaning the filter screen 2-361 and the upper shell of the air duct, flows to the bottom of the vertical air duct 2-32 and is discharged through the lower drain 2-35; water in the drain water path 2-3633 flows into the drain channel 2-34 through the drain outlet 2-365, flows to the bottom of the vertical air duct 2-32 through the drain channel 2-34, and is discharged through the lower drain 2-35.

[0226] like Figures 14 to 15 As shown, in some specific embodiments, the air duct is composed of a lower air duct housing 2-311 and an upper air duct housing. Both the lower air duct housing 2-311 and the upper air duct housing are provided with grooves. The lower air duct housing 2-311 and the groove opening on the upper air duct housing are engaged to form an air duct.

[0227] Specifically, the lower housing 2-311 of the air duct is provided with a groove, which is a side opening, including a first groove 2-3111 and a second groove 2-3112; the first groove 2-3111 is located directly below the second groove 2-3112, and a lower discharge port 2-35 is provided on the side of the first groove 2-3111 away from the second groove 2-3112 for discharging sewage.

[0228] Furthermore, a baffle 2-3113 supporting the condenser filter device 2-36 is provided between the first groove 2-3111 and the second groove 2-3112. The baffle 2-3113 is located in the middle of the lower housing 2-311 of the air duct and is used to support and place the condenser filter device 2-36. The two ends of the baffle 2-3113 in the length direction are respectively connected to the lower housing 2-311 of the air duct. One side of the baffle 2-3113 in the width direction is connected to the lower housing 2-311 of the air duct, and the other side extends towards the opening of the air duct groove and is not connected to the upper housing of the air duct. The width direction of the baffle 2-3113 is perpendicular to the wall of the lower housing 2-3111 of the air duct connected to the width direction of the baffle 2-3113, which enables the circulating airflow to completely pass through the filter screen 2-361 on the condenser filter device 2-36 from the first groove 2-3111 to the second groove 2-3112.

[0229] Specifically, there are opposing notches on the walls of the condensing air duct 2-31 on both sides of the opening of the second groove 2-3112, for connecting with the condensing filter device 2-36.

[0230] like Figure 15 As shown, in this embodiment, the condensation duct 2-31 is L-shaped and consists of a vertical duct 2-32 and a horizontal duct 2-33. The bend where the horizontal duct 2-33 connects to the vertical duct 2-32 is located in the second groove 2-3112. The horizontal duct 2-33 extends along the side opposite to the opening of the second groove 2-3112 and is perpendicular to the vertical duct 2-32.

[0231] Preferably, the cross-section of the condenser duct 2-31 at the bend between the horizontal duct 2-33 and the vertical duct 2-32 is an inverted triangle, which is used to guide the circulating airflow.

[0232] Specifically, an air outlet communicating with the second groove 2-3112 is provided above the horizontal air duct 2-33 in the second groove 2-3112. The air outlet 2-331 is circular, and the axis of the air outlet 2-331 is perpendicular to the extension direction of the opening of the second groove 2-3112. The air inlet 2-321 is located inside the first groove 2-3111 and on the side wall opposite to the opening of the first groove 2-3111.

[0233] Preferably, the air inlet 2-321 is elliptical, and the opening size is half the side wall area of ​​the opposite side of the opening of the first groove 2-3111, thereby improving the circulation efficiency of the circulating air in the condenser duct 2-31.

[0234] Preferably, the groove in the lower housing 2-311 of the air duct also includes a drainage groove for draining excess water; the drainage groove is provided with water-blocking ribs, and the water-blocking ribs 2-3634 are arranged opposite each other on the walls on both sides of the drainage groove to control the water flow rate and guide the water flow.

[0235] Specifically, the drainage groove is located on one side of the first groove 2-3111 and the second groove 2-3112. The end of the drainage groove near the air outlet 2-331 is connected to the second groove 2-3112, and the end of the drainage groove away from the air outlet 2-331 is connected to the first groove 2-3111.

[0236] The structure of the upper shell of the air duct is matched with the structure of the lower shell 2-311 of the air duct, and is fastened to the lower shell 2-311 of the air duct, so that the drain trough forms a drain channel 2-34, and the first groove 2-3111 and the second groove 2-3112 form a vertical air duct 2-32, which is connected to the horizontal air duct 2-33 in the second groove 2-3112.

[0237] The circulating airflow of the drying device enters the vertical air duct 2-32 from the air inlet 2-321, passes through the condenser filter 2-36, then passes through the horizontal air duct 2-33, and flows out from the air outlet 2-331. The circulating airflow continuously repeats the above steps to carry out the drying work.

[0238] In this embodiment, a clothing processing device is also disclosed, which is equipped with the aforementioned drying device.

[0239] like Figures 14 to 18 As shown in this embodiment, a drying device is introduced. The condensation module of the drying device includes a condensation air duct 2-31 and a condensation filter device 2-36 disposed in the air duct.

[0240] like Figures 15-16 As shown, in this embodiment, the condensation filter device 2-36 is installed in the vertical air duct 2-32, covering the entire cross section of the condensation air duct 2-31, including the cross section of the condensation air duct 2-31 at the bend where the horizontal air duct 2-33 connects to the vertical air duct 2-32.

[0241] Specifically, in this embodiment, the condensation filter device 2-36 includes a filter support 2-362 and a filter 2-361 disposed on the filter support 2-362. The filter 2-361 is disposed on the side of the condensation duct 2-31 cross-section away from the bend of the condensation duct 2-31 in the condensation filter device 2-36, facing upstream of the airflow, so that impurities such as lint carried in the circulating airflow can be attached to the filter 2-361, thereby achieving filtration of the circulating airflow. The filter support 2-362 is arranged around the filter 2-361. Spray water channels 2-363 are provided in the filter support 2-362 located above, below, and on both sides of the filter 2-361. The spray water channels 2-363 located above and below the filter 2-361 extend along the length direction of the condensation filter device 2-36. The spray water channels 2-363 located on both sides of the filter 2-361 extend along the width direction of the condensation filter device 2-36.

[0242] Furthermore, the filter screen 2-361 is a metal filter screen, and it is in-mold injection molded with the filter screen support 2-362 to ensure integration and prevent dirt from adhering to the assembly connection, which would affect the cleaning effect on the circulating airflow and improve the user experience.

[0243] like Figures 16 to 18 As shown, in this embodiment, the filter support 2-362 includes a support body and a spray water channel cover 2-366. The support body is used to support the filter screen 2-361. A groove is provided on the top of the filter support 2-362, and the spray water channel cover 2-366 is fastened to the groove of the water channel, forming a spray water channel 2-363 between the cover and the support body. The spray water channel cover 2-366 and the filter support 2-362 are connected by fusion bonding to ensure the sealing of the spray water channel 2-363 and improve the efficiency of filter cleaning.

[0244] like Figure 17As shown, in this embodiment, the spray water path is provided with water-blocking ribs 2-3634 inside. The water-blocking ribs 2-3634 are set at different positions to form spray water paths 2-363 with different functions. The filter screen supports 2-362 located above, below and on both sides of the filter screen 2-361 are provided with interconnected spray water paths 2-363, each including an inlet water path 2-3631, an outlet water path 2-3632 and a drain water path 2-3633. The inlet water path 2-3631 and the drain water path 2-3633 are interconnected and arranged side by side through the outlet water path 2-3632. The outlet water path 2-3632 is located on the side of the spray water path 2-363 close to the filter screen 6. The inlet water path 2-3631 and the drain water path 2-3633 are respectively located on the same side of the outlet water path 2-3632.

[0245] Specifically, the spray water path 2-363 located above the filter screen 2-361 is the upper spray water path. The inlet and outlet water paths of the upper spray water path are connected through the outlet water path. The inlet water path is connected to the right spray water path located to the right of the filter screen 2-361 through its first inlet. The outlet water path is connected to the left spray water path located to the left of the filter screen through its first outlet. The first outlet is equivalent to the inlet of the left spray water path. The left and right spray water paths are connected to the lower spray water path located below the filter screen through the left and right outlet water paths, respectively. The outlet water path of the lower spray water path is connected to the left outlet water path. Excess water in the left and lower spray water paths is discharged through the outlet water path in the outlet water path to prevent excessive water pressure from damaging the water path and to extend the service life of the condensation filter device 2-36.

[0246] Specifically, the spray water path 2-363 has multiple spray nozzles on the side near the filter screen 6. The spray nozzles are located on the side of the spray water path 2-363 near the upstream side of the airflow direction, and the multiple spray nozzles extend along the length of the condensation filter device 2-36. The spray nozzles include a first spray nozzle 2-367 and a second spray nozzle 2-3661. The first spray nozzle 2-367 is correspondingly arranged with the filter screen 2-361 and extends partially to the downstream side of the airflow direction for thoroughly cleaning the filter screen 2-361. The second spray nozzle 2-3661 is located on the spray water path cover 2-366 and faces the filter screen 2-361 near the upstream side of the airflow direction, so as to spray the filter screen 2-361 near the upstream side of the airflow direction and thoroughly clean the lint.

[0247] like Figures 14 to 15 As shown, in some specific embodiments, the air duct is composed of a lower air duct housing 2-311 and an upper air duct housing. Both the lower air duct housing 2-311 and the upper air duct housing are provided with grooves. The lower air duct housing 2-311 and the groove opening on the upper air duct housing are engaged to form an air duct.

[0248] Specifically, the condenser duct 2-31 is L-shaped and consists of a vertical duct 2-32 and a horizontal duct 2-33.
