Description

TECHNICAL FIELD

[0001] The present application belongs to the field of clothes dryers, and particularly relates to a clothes dryer lint collecting device, a clothes dryer and a control method of the clothes dryer. BACKGROUND

[0002] During the operation of the clothes dryer, lint and fluff on the clothes inevitably flow with the drying air and are blocked by the lint filter device and remain on the lint filter device. The lint and fluff accumulate on the lint filter device with the use of the clothes dryer, which blocks the flow of the drying air, reduces the drying efficiency of the clothes dryer and deteriorates the drying effect.

[0003] To solve this problem, the lint filter device is usually designed as a detachable structure in the prior art. The filter device needs to be disassembled and cleaned after the clothes dryer is used for a period of time, or the filter device is cleaned by spraying water through a cleaning device, so as to ensure the normal operation of the clothes dryer.

[0004] A lint filter device is disclosed in Chinese Patent Application No. CN201210575631.7, which comprises a first lint filter layer, a second lint filter layer and a third lint filter layer. The first lint filter layer and the second lint filter layer are installed below the door body of the front air duct at the air outlet end of the drum of the clothes dryer and are mutually clamped. The third lint filter layer is arranged in the internal air path of the clothes dryer. The lint is filtered and collected through the multiple filter layers, and the filter device is removed for cleaning. Although the above-mentioned scheme realizes the filtering and collecting of the lint, the user cannot know the accumulation of the lint in the lint filter device. The user experience is reduced due to the high cleaning frequency of the user, or the circulation efficiency of the circulating air is reduced due to the failure of the user to clean in time, which affects the drying performance of the clothes dryer.

[0005] Chinese Patent Application No. CN201910817825.5 discloses a filter device and a method for judging the degree of blockage of the filter device. Specifically, the static pressure at the inlet and outlet of the condensing end is detected before drying starts after washing is completed, and the inlet static pressure P1 and the outlet static pressure P2 are obtained. If P1-P2≥the preset static pressure difference threshold, it is judged that the filter device needs to be cleaned, and a warning is sent to the user. Although the above-mentioned scheme can judge the blockage of the filter device through the pressure difference, the filter device does not have a separate lint storage structure, and the user cannot clean the filter device completely. In addition, the above-mentioned scheme only detects before drying starts. Since the filter device does not have a separate component for collecting lint, if there is a large amount of lint in the clothes, the drying effect may be reduced due to the accumulation of the lint during the drying process. At this time, the user cannot know the accumulation of the lint in time, and the filter device cannot be disassembled for cleaning during the drying process.

[0006] Therefore, the present application is proposed. SUMMARY

[0007] One of the purposes of the present application is to provide a lint collecting device for the above-mentioned problems in the prior art, which is arranged in the air duct of a clothes dryer, comprising a first air duct and a second air duct for separating lint from circulating air, a collecting part for collecting lint, and a detection part for detecting the air resistance or humidity at the mesh structure, and judging the accumulation of lint in the collecting part through the detection result of the detection part.

[0008] Another purpose of the present application is to provide a control method of a clothes dryer with a lint collecting device, which compares the first parameter obtained by detecting the air resistance or humidity at the mesh structure with a preset parameter threshold, and prompts the user to clean the collecting part when the first parameter is greater than the parameter threshold, so as to avoid the influence of excessive accumulation of lint on the drying efficiency.

[0009] In order to achieve the above-mentioned purposes, the first aspect of the present application provides a lint collecting device arranged in the air duct of a clothes dryer, comprising,

[0010] A first air duct, which is internally provided with a filtering unit for filtering lint;

[0011] A second air duct arranged side by side with the first air duct, which is communicated with the first air duct at one side close to the first air duct, for receiving lint and discharging lint from the air outlet end of the second air duct;

[0012] A collecting part with a mesh structure, which is communicated with the air outlet end of the second air duct, for collecting lint;

[0013] A detection part arranged on the collecting part, for detecting the air resistance or humidity at the mesh structure.

[0014] In the above-mentioned scheme, the lint filtered out by the first air duct is collected in the collecting part through the second air duct, which does not affect the circulation efficiency of the circulating air in the air duct; as the accumulation of lint in the collecting part increases, the mesh structure is blocked by the lint, which causes the air resistance to increase, the circulating air carrying the lint into the collecting part cannot smoothly pass through the mesh structure to return to the air duct of the clothes dryer, and further causes the humidity at the mesh structure to significantly increase, so that the accumulation of lint in the collecting part can be more accurately judged by detecting the air resistance or humidity at the mesh structure.

[0015] Further, the collecting part comprises,

[0016] A collecting box with a mesh structure, which is arranged at the air outlet end of the second air duct and communicated with the air outlet end of the second air duct, for collecting lint;

[0017] The detection part is arranged inside the collecting box.

[0018] The detection part is arranged in the collection box, which can more accurately detect the wind resistance and humidity change at the filter screen. If the detection part is arranged outside the collection box, the detection result may be low due to the influence of circulating air in the air duct of the clothes dryer, which affects the correct judgment of the accumulation of lint in the collection box.

[0019] Further, the mesh structure part replaces the box body structure of the collection box,

[0020] The detection part and the mesh structure are arranged on the same side of the collection box.

[0021] Further, the mesh structure is a filter screen, comprising,

[0022] The first filter screen is arranged on one side of the collection box close to the air outlet end of the first air duct;

[0023] The detection part is arranged on the first filter screen.

[0024] In the above scheme, the first filter screen is arranged on one side of the collection box close to the air outlet end of the first air duct. The covering area of the filter screen is increased to improve the efficiency of circulating air passing through the first filter screen. The wind resistance of the deposited lint to the filter screen gradually increases with the increase of the accumulated amount, so that the collection box can collect more lint, reduce the cleaning frequency of the user, and improve the user experience.

[0025] Alternatively, as an alternative to the above scheme, the detection part is arranged on the box body structure of the collection box on the same side of the first filter screen.

[0026] The above scheme avoids the influence of the detection part on the circulation efficiency of the circulating air, and also avoids the attachment of lint on the detection part to cause inaccurate detection results.

[0027] Further, the first filter screen is arranged on one side of the collection box close to the air outlet end of the second air duct.

[0028] In the above scheme, after the circulating air sends the lint into the bottom of the collection box, it needs to return to the first filter screen close to the air outlet end of the second air duct and return to the air duct of the clothes dryer. The above process generates a small vortex in the collection box, which can separate some lint attached to the first filter screen from the first filter screen, and further improves the amount of lint that can be collected in the collection box.

[0029] Further, the mesh structure is a filter screen, comprising,

[0030] The first filter screen is arranged on one side of the collection box close to the air outlet end of the first air duct;

[0031] The second filter screen is arranged on one side of the collection box close to the air outlet end of the first air duct and spaced from the first filter screen;

[0032] The detection part is arranged on the box body structure between the first filter screen and the second filter screen.

[0033] The above scheme sets the first filter screen and the second filter screen on the side of the collecting box close to the air outlet end of the first air duct, further expanding the coverage area of the filter screen; the detection part is arranged on the box body structure between the first filter screen and the second filter screen, which can detect the air resistance or humidity of the filter screen while avoiding affecting the exhaust of circulating air by arranging the detection part on the filter screen, reducing the influence of the collecting box on the circulating efficiency of the circulating air, and avoiding the influence of the line scraps attached to the detection part on the accuracy of the detection result.

[0034] Further, the first filter screen is arranged close to the air outlet end of the second air duct, and the second filter screen is arranged away from the air outlet end of the second air duct, and the detection part detects the air resistance or humidity of the first filter screen.

[0035] Further, the second filter screen is arranged to be inclined to the outside of the collecting box along the direction close to the bottom of the collecting box.

[0036] The above setting scheme further reduces the speed of the second filter screen being attached and blocked by the line scraps. Since the second filter screen is arranged to be inclined, part of the line scraps that are not firmly attached may fall off the filter screen under the blowing of the circulating air. When the stored line scraps do not overflow the second filter screen, the second filter screen can be completely blocked, reducing the blocking effect of the line scraps on the circulating air.

[0037] Further, the second filter screen is arranged to be inclined to the outside of the collecting box along the direction away from the air outlet end of the second air duct.

[0038] In the above scheme, part of the line scraps attached to the second filter screen can fall off the second filter screen under the influence of gravity and circulating air. Since the blocking effect of the line scraps on the second filter screen is reduced, the line scraps are less likely to be attached to the first filter screen, reducing the alarm frequency of the clothes dryer and increasing the amount of line scraps that can be collected in the collecting box when the alarm is triggered.

[0039] Further, the collecting part further comprises,

[0040] The supporting part is connected with the air outlet end of the second air duct and has a mounting port for mounting the collecting box;

[0041] The collecting box is detachably connected with the supporting part through the mounting port, and the collecting box is in communication with the air outlet end of the second air duct when the collecting box is mounted in place.

[0042] Further, the other side of the supporting part opposite to the mounting port has an opening, and the collecting box is in communication with the air duct of the clothes dryer through the mesh structure and the opening when the collecting box is mounted in place.

[0043] The above scheme realizes the stable connection of the collecting box and the air outlet end of the second air duct through the supporting part, and the user can more easily disassemble and install the collecting box.

[0044] Further, the supporting part further comprises,

[0045] The positioning rib is arranged inside the supporting part and is used for positioning installation of the collection box.

[0046] The collection box abuts against the positioning rib when being installed in place.

[0047] The above scheme realizes positioning of installation of the collection box, and users can more easily install the collection box in place and more easily take out the collection box, thereby improving user experience.

[0048] The second aspect of the application provides a control method of the above clothes dryer, comprising the following steps:

[0049] S1, after the drying process starts, the detection part continuously detects the wind resistance or humidity at the net structure to obtain a first parameter, and the first parameter is sent to the computer board of the clothes dryer.

[0050] S2, the computer board compares the first parameter with a preset threshold value, and when the first parameter is greater than the preset threshold value, an alarm is sent to the user.

[0051] The first parameter includes a first wind resistance parameter and a first humidity parameter, the preset threshold value includes a wind resistance threshold value and a humidity threshold value, when the first parameter is the first wind resistance parameter, the preset threshold value is the wind resistance threshold value, and when the first parameter is the first humidity parameter, the preset threshold value is the humidity threshold value.

[0052] In the above scheme, the detection part continuously detects the wind resistance or humidity at the net structure, and as the lint accumulates, the net structure is gradually blocked by the lint, which reduces the speed of the circulating air passing through the net structure, and at this time, the wind resistance at the net structure increases, and when the first wind resistance parameter detected is greater than the wind resistance threshold value, it indicates that the degree of blockage of the net structure is high, and it can be judged that the lint accumulates more at this time and needs to be cleaned. At the same time, as the lint accumulates at the net structure, the circulating air cannot pass through the net structure smoothly, and the moisture in the circulating air will accumulate at the net structure, causing the humidity to increase, and when the first humidity parameter detected is greater than the humidity threshold value, it indicates that the degree of blockage of the net structure is high, and it can be judged that the lint accumulates more at this time and needs to be cleaned.

[0053] The application has the following beneficial effects:

[0054] The detection part is arranged on the collecting part to detect the wind resistance or humidity at the mesh structure, so that the clothes dryer can accurately judge the accumulation of lint according to the change of the wind resistance or humidity; the detection part is arranged inside the collecting box, so that the detection accuracy is improved, and the influence of the circulating air in the air duct of the clothes dryer on the accuracy of the detection result is avoided; the mesh structure is arranged on one side of the collecting box close to the air outlet end of the first air duct, so that the mesh structure has a large area, and the circulating air carrying the lint into the collecting box is not hindered; the mesh structure is a filter screen, which includes a first filter screen and a second filter screen, and the first filter screen and the second filter screen are arranged at intervals, so that the covering area of the filter screen is further expanded while the strength of the collecting box is ensured; the detection part is arranged on the box body structure between the first filter screen and the second filter screen, so that the discharge of the circulating air is not blocked, and the attachment of the lint on the detection part is also avoided, so that the detection accuracy is reduced; as the lint accumulates at the mesh structure, the wind resistance at the mesh structure increases, the circulating air cannot pass through the mesh structure smoothly, and the humidity at the mesh structure increases, so that the accumulation of the lint in the collecting part can be accurately judged by detecting the wind resistance or humidity at the mesh structure, and then an alarm is sent to the user, so that the lint does not affect the drying efficiency due to the untimely cleaning of the user.

[0064] Embodiment one

[0065] As an embodiment of the present application, the embodiment provides a lint collecting device arranged in the air duct 6 of the clothes dryer, as shown in the drawings, comprising, Figure 5

[0066] The first air duct 4 is internally provided with a filtering unit for filtering lint;

[0067] The second air duct 5 is arranged side by side with the first air duct 4, and the side close to the first air duct 4 is in communication with the first air duct 4, for receiving lint and discharging the lint from the air outlet end of the second air duct 5;

[0068] The collecting part 1 has a mesh structure 2 in communication with the air outlet end of the second air duct 5, for collecting lint;

[0069] The detection part 3 is arranged on the collecting part 1, for detecting the wind resistance or humidity at the mesh structure 2.

[0070] In the embodiment, as shown in the drawings, the collecting part 1 comprises, Figure 1

[0071] The collecting box 11 has a mesh structure 2, and is arranged at the air outlet end of the second air duct 5 in communication with the air outlet end of the second air duct 5, for collecting lint;

[0072] The detection part 3 is arranged on the mesh structure 2 inside the collecting box 11.

[0073] The above scheme arranges the detection part 3 inside the collecting box 11, avoiding the influence of the circulating air in the air duct 6 of the clothes dryer on the detection result of the detection part 3, which may cause the wind resistance or humidity detected by the detection part 3 to decrease, affecting the correct judgment of the clothes dryer on the accumulation of lint. ​​

[0074] Further, the mesh structure 2 comprises,

[0075] The first filter screen 21 is arranged on the side of the collecting box 11 close to the air outlet end of the first air duct 4, and partially replaces the box body structure of the collecting box 11.

[0076] The detection part 3 is arranged on the first filter screen 21.

[0077] Alternatively, as an alternative to the above scheme, as shown in the figure, the detection part 3 is arranged on the same side of the mesh structure 2 and on the box body structure of the collecting box 11. Figure 2

[0078] The above alternative scheme arranges the detection part 3 on the same side of the mesh structure 2 and on the box body structure of the collecting box 11, which ensures accurate detection of the wind resistance and humidity at the mesh structure 2, avoids affecting the smooth passage of circulating air arranged on the mesh structure 2, and also avoids the attachment of lint on the detection part 3 affecting the detection accuracy.

[0079] Further, in the above scheme, the lint is driven into the collecting box 11 by part of the circulating air, in order to avoid affecting the collection effect, the circulating air will return to the air duct 6 of the clothes dryer from the mesh structure 2 after sending the lint into the collecting box 11, in order to improve the accumulation of the lint in the collecting box 11, the first filter screen 21 is arranged on the side of the collecting box 11 close to the air outlet end of the second air duct 5.

[0080] Embodiment Two

[0081] As another embodiment of the present application, the embodiment provides a lint collecting device, which is different from the first embodiment in that, in the embodiment, as shown in the figure, the mesh structure 2 comprises, Figure 3

[0082] The first filter screen 21 is arranged on the side of the collecting box 11 close to the air outlet end of the first air duct 4;

[0083] The second filter screen 22 is arranged on the side of the collecting box 11 close to the air outlet end of the first air duct 4 and is spaced apart from the first filter screen 21;

[0084] The detection part 3 is arranged on the first filter screen 21.

[0085] ​​The above scheme expands the coverage of the filter screen by providing the first filter screen 21 and the second filter screen 22 on the collecting box 11, so that the circulating air can pass through the mesh structure 2 more smoothly and return to the air duct 6 of the clothes dryer, the attachment surface of the lint is larger, and the influence of the attachment of the lint on the circulating efficiency of the circulating air is reduced. Meanwhile, the first filter screen 21 and the second filter screen 22 are arranged at intervals, and the box body structure is arranged between the first filter screen and the second filter screen 22, thereby improving the strength of the collecting box 11 and the filter screen. In the case of a large amount of accumulated lint, the filter screen is not easily damaged, and the stability is improved.

[0086] Alternatively, as an alternative to the above scheme, the detection part 3 is arranged on the box body structure between the first filter screen 21 and the second filter screen 22.

[0087] The above scheme arranges the detection part 3 on the box body structure, which avoids the blocking of the circulating air by the detection part 3 and also avoids the attachment of the lint on the detection part 3 affecting the detection result. Meanwhile, if the detection part 3 is arranged on the mesh structure 2, the flatness of the mesh structure 2 is affected, the lint is more easily attached to the detection part 3, and gradually attached to the entire mesh structure 2 centering on the detection part 3, which increases the attachment speed of the lint and further increases the frequency of user receiving alarms, thereby reducing the use experience.

[0088] Embodiment Three

[0089] As another embodiment of the present application, the present embodiment is a further improvement on the technical scheme in Embodiment Two. Specifically, in the present embodiment, as shown in Figure 4 the first filter screen 21 is arranged close to the air outlet end of the second air duct 5, the second filter screen 22 is arranged away from the air outlet end of the second air duct 5, and the detection part 3 detects the air resistance or humidity of the first filter screen 21.

[0090] The above scheme arranges the first filter screen 21 and the second filter screen 22 at positions close to and away from the air outlet end of the second air duct 5, respectively, so that the circulating air entering the collecting box 11 can be discharged more stably from the mesh structure 2. If the first filter screen 21 and the second filter screen 22 are both arranged at positions close to the air outlet end of the second air duct 5, the circulating air that carries the lint into the bottom of the collecting box 11 needs to be folded back and discharged from the mesh structure 2, which may generate vortex at the bottom of the collecting box 11 and affect the normal collection of the lint, the attachment speed of the lint at the mesh structure 2 is also faster, and the user needs to clean the collecting box 11 more frequently. If the first filter screen 21 and the second filter screen 22 are both arranged at positions away from the air outlet end of the second air duct 5, as the lint accumulates, the mesh structure 2 is quickly blocked or covered by the lint, which also increases the cleaning frequency of the user and reduces the use experience of the user.

[0091] Further, the second filter screen 22 is arranged obliquely outward of the collecting box 11 in a direction away from the air outlet end of the second air duct 5.

[0092] In the above scheme, due to the oblique arrangement of the second filter screen 22, part of the line debris that is not firmly attached may fall off from the second filter screen 22 under the action of gravity and circulating air, and the second filter screen 22 can be completely blocked only when the stored line debris reaches the second filter screen 22, which reduces the blocking effect of the collecting box 11 on the circulating air. At the same time, due to the reduced blocking effect of the line debris on the second filter screen 22, the line debris is less likely to be attached to the first filter screen 21, which reduces the alarm frequency of the clothes dryer and increases the amount of line debris that can be collected in the collecting box 11 when the alarm is triggered.

[0093] Embodiment Four

[0094] As another embodiment of the present application, the present embodiment provides a line debris collecting device having the same structure as that of Embodiment One, except that in the present embodiment, the line debris collecting device further comprises,

[0095] The supporting portion is connected to the air outlet end of the second air duct and has a mounting opening for mounting the collecting box;

[0096] The collecting box is detachably connected to the supporting portion through the mounting opening, and the collecting box is in communication with the air outlet end of the second air duct when the collecting box is mounted in place.

[0097] The above scheme realizes stable connection of the collecting box and the air outlet end of the second air duct through the supporting portion, and the user can more easily disassemble and mount the collecting box.

[0098] Further, the supporting portion comprises,

[0099] The positioning rib is arranged inside the supporting portion and is used for positioning the mounting of the collecting box in place;

[0100] The collecting box is in abutment with the positioning rib when the collecting box is mounted in place.

[0101] The above scheme realizes positioning of the mounting of the collecting box in place, and the user can more easily mount the collecting box in place and more easily take out the collecting box, thereby improving the user experience.

[0102] The present application also provides a control method of a clothes dryer having the above line debris collecting device, specifically comprising:

[0103] Embodiment Five

[0104] As another embodiment of the present application, the present embodiment provides a control method of a clothes dryer having the line debris collecting device of Embodiment One, comprising the following steps:

[0105] S1, after the drying process starts, the detection part continuously detects the wind resistance or humidity at the mesh structure, obtains a first parameter, and sends the first parameter to the computer board of the clothes dryer;

[0106] S2, the computer board compares the first parameter with a preset threshold value, and if the first parameter is greater than the preset threshold value, an alarm is sent to the user.

[0107] In the embodiment, the first parameter includes a first wind resistance parameter and a first humidity parameter, the preset threshold value includes a wind resistance threshold value and a humidity threshold value, when the first parameter is the first wind resistance parameter, the preset threshold value is the wind resistance threshold value, and when the first parameter is the first humidity parameter, the preset threshold value is the humidity threshold value.

[0108] In the above scheme, the detection part continuously detects the wind resistance or humidity at the mesh structure, as the lint accumulates, the mesh structure is gradually blocked by the lint, causing the speed of the circulating air passing through the mesh structure to decrease, at this time, the wind resistance at the mesh structure increases, and when the first wind resistance parameter detected is greater than the wind resistance threshold value, it indicates that the degree of blockage of the mesh structure is high, and it can be judged that the lint accumulates more at this time and needs to be cleaned; at the same time, as the lint accumulates at the mesh structure, the circulating air cannot pass through the mesh structure smoothly, and the moisture in the circulating air will accumulate at the mesh structure, causing the humidity to increase, and when the first humidity parameter detected is greater than the humidity threshold value, it indicates that the degree of blockage of the mesh structure is high, and it can be judged that the lint accumulates more at this time and needs to be cleaned, through the above scheme, an alarm is sent to the user in time when the lint collection is affected by the circulating air circulation, prompting the user to clean, the user can clean the collection box in time after receiving the alarm, and is not affected by the running state of the clothes dryer, improving the user's experience.

[0109] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in any form, although the present application has been disclosed as above with a preferred embodiment, however, it is not intended to limit the present application, any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, the implementation scheme in the above embodiment can be further combined or replaced, as long as it does not deviate from the content of the technical solution of the present application, any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application, all still belong to the scope of the present application.

When the first parameter is the first wind resistance parameter, the preset threshold is the wind resistance threshold. When the first parameter is the first humidity parameter, the preset threshold is the humidity threshold.
