[0076] Background

[0077] Currently available clothing processing equipment has a drying function, which brings great convenience to people and enables daily quick drying and wearing, and drying of clothes on damp days. However, if the clothes are dried for a long time, the hair that falls off the clothes will accumulate in the air duct along with the wind flow, causing the air duct to be dirty and blocked, affecting the circulation of heat and the original wind field, and thus affecting the drying effect of the clothes. The embodiment of the present application provides a drying system, a clothing processing device, and a method for processing dirty and blocked air ducts of a clothing processing device, which respectively sets temperature sensors on the air inlet side and the exhaust side of the first connecting section, and can judge whether the first connecting section is dirty and blocked according to the temperature difference between the airflow on the air inlet side and the airflow on the exhaust side of the first connecting section. At the same time, by setting a spray component, when it is judged that the first connecting section is dirty and blocked, the spray component can be used to spray the first connecting section in real time, thereby removing the dirty and blocked hair in the first connecting section.

[0078] Specifically, Figure 1-Figure 6 As shown, a first aspect of an embodiment of the present application provides a drying system, which is applied to a clothing processing device, wherein the clothing processing device comprises a clothing processing drum 100, a clothing loading port 101 is provided on the front side of the clothing processing drum 100, and the clothing processing drum 100 comprises an inner drum 100a and an outer drum 100b which are mutually nested, and the drying system comprises a heating air duct, a condensing air duct 200, and a fan air duct connected between the heating air duct and the condensing air duct 200, wherein the heating air duct is arranged close to the front drum of the outer drum 100b relative to the condensing air duct, and the condensing air duct 200 is arranged close to the rear drum of the outer drum 100b relative to the heating air duct;

[0079] The condensation air duct includes a condensation area formed on the outer side of the rear bottom of the outer cylinder 100b;

[0080] The rear bottom of the outer cylinder 100b is provided with a first vent and a second vent, and the first vent and the second vent are arranged at different heights along the rear bottom of the outer cylinder 100b, wherein the first vent is arranged at the upper part of the rear bottom of the outer cylinder 100b, and the second vent is arranged at the lower part of the rear bottom of the outer cylinder 100b, wherein a small part of the dry air flow in the outer cylinder 100b flows into the condensation area through the first vent to form a first fluid, and the first fluid flows from top to bottom, and most of the dry air flow in the outer cylinder 100b flows into the condensation area through the second vent to form a second fluid, and the second fluid flows from bottom to top;

[0081] An air outlet 204 is also provided at the upper part of the condensation zone. The air outlet 204 is located between the first air outlet and the second air outlet and close to the first air outlet. Under the action of the fan, the first fluid and the second fluid both flow from the air outlet 204 into the fan duct, and then flow from the fan duct into the heating duct, and finally return to the inner cylinder 100a.

[0082] The condensation air duct 200 includes a first connection section 201, a second connection section 202 and a main condensation section 203, wherein one end of the first connection section 201 is connected to the first vent, and the other end is connected to the top of the main condensation section 203, one end of the second connection section 202 is connected to the second vent, and the other end is connected to the main condensation section 203, and the main condensation section 203 extends between the upper and lower parts of the rear cylinder, and a condensation area extending up and down is formed inside the main condensation section 203;

[0083] Among them Figure 6 As shown, at least a portion of the length of the first connecting section 201 is formed as a corrugated section;

[0084] The drying system also includes a first temperature sensor 301 and a second temperature sensor 302;

[0085] The first temperature sensor 301 is arranged above the inner side of the rear bottom of the outer cylinder 100b and near the first vent, and is used to detect the first temperature of the airflow in the outer cylinder 100b before it flows into the first connecting section 201 from the first vent. The second temperature sensor 302 is arranged at the top of the main condensing section 203 and at the exhaust port side of the first connecting section 201, and is used to detect the second temperature of the airflow in the outer cylinder after it flows out of the first connecting section 201.

[0086] The drying system further includes a spray assembly 400, which is disposed above the condensation zone and between the first temperature sensor 301 and the second temperature sensor 302, and is used to flush the hair scraps in the first connecting section 201;

[0087] The drying system also includes a control device, which is designed to control the opening and closing of the spray assembly 400 according to the difference between a first temperature of the airflow in the outer drum 100b before flowing into the first connecting section 201 and a second temperature of the airflow in the outer drum 100b after flowing into the first connecting section 201.

[0088] In the embodiment of the present application, temperature sensors are respectively arranged on the air inlet side and the exhaust port side of the first connecting section 201. In this way, it is possible to determine whether the first connecting section 201 is dirty or clogged based on the temperature difference between the airflow on the air inlet side and the airflow on the exhaust port side of the first connecting section 201. At the same time, by setting up a spray component 400, when it is determined that the first connecting section 201 is dirty or clogged, the spray component 400 can be used to spray the first connecting section 201, thereby removing the dirty hair debris in the first connecting section 201.

[0089] Specifically, when the temperature difference between the airflow on the air inlet side and the airflow on the exhaust side of the first connecting section 201 exceeds the preset temperature difference, it means that dirt blockage has occurred in the first connecting section 201. At this time, the spray assembly 400 can be turned on to flush the inside of the first connecting section 201 to remove the hair debris inside the first connecting section 201. When the temperature difference between the airflow on the air inlet side and the airflow on the exhaust side of the first connecting section 201 does not exceed the preset temperature difference, it means that dirt blockage has not occurred in the first connecting section 201, and there is no need to flush the inside of the first connecting section 201.

[0090] It should be noted that if Figure 6 As shown, at least part of the length of the second connecting section 202 for connecting with the second vent is also formed as a corrugated section. Preferably, the first connecting section 201 and the second connecting section 202 are both corrugated tubes.

[0091] It should be noted that, since the first connecting section 201 and the second connecting section 202 for connecting with the first vent and the second vent in the embodiment of the present application adopt bellows, the airflow is easily accumulated in the bellows when passing through the bellows, thereby affecting the ventilation effect of the bellows. By setting a temperature sensor to respectively collect the temperature on the air inlet side and the exhaust side of the bellows, it is possible to reflect whether there is dirt and blockage inside the bellows through the change in temperature, thereby effectively monitoring the dirt and blockage inside the bellows and cleaning it in time.

[0092] It should also be noted that the reason why the temperature difference between the air inlet side and the air outlet side of the upper first connecting section 201 is obtained in the embodiment of the present application, but not the temperature difference between the air inlet side and the air outlet side of the lower first connecting section 201, is that if a temperature sensor is provided at the lower second connecting section 202, the condensed water flowing from top to bottom will contact the temperature sensor at the bottom and affect the detection accuracy. In addition, when the first connecting section 201 is rinsed by providing a spray assembly 400 at the top, the rinse water can also flow from top to bottom along the main condensation section 203, so that the main condensation section 203 and the second connecting section 202 can also be rinsed.

[0093] It should also be noted that the reason why bellows are arranged at the first air vent and the second air vent to connect the main condensation section in the embodiment of the present application is that, on the one hand, the bellows can facilitate the installation of the main condensation section, and on the other hand, when the main condensation section and the air vent are connected together through the bellows, the sealing effect during the connection can also be improved.

[0094] Furthermore, in some embodiments, the control device determines the degree of dirtiness and blockage of the first connecting section according to the difference between the first temperature and the second temperature, and controls the spray assembly 400 to clean the lint from the first connecting section 201 according to the preset rhythm and water flow intensity according to the degree of dirtiness and blockage.

[0095] That is, the spray assembly 400 in the embodiment of the present application can perform targeted flushing on the first connecting section 201 according to the degree of dirt and blockage of the first connecting section 201 , thereby improving the cleaning effect of the first connecting section 201 .

[0096] Further, in some embodiments, Figure 5 As shown, the spray assembly 400 has a first spray port and a second spray port. The first spray port is used for spraying toward the first connecting section 201 , and the second spray port is used for spraying toward the main condensation section 203 .

[0097] In this way, on the one hand, the flushing water sprayed through the first spray port can flush the inside of the first connecting section 201, and on the other hand, the flushing water sprayed through the second spray port can also flush the main condensation section 203 from top to bottom, thereby being able to perform all-round flushing of the condensation air duct on the rear side of the outer cylinder 100b.

[0098] It should be noted that if Figure 6 As shown, a condensation valve 205 is also provided in the condensation duct 200 in the embodiment of the present application, wherein the condensation valve 205 is used to inject condensation water into the main condensation section 203 when the clothing processing equipment executes a drying program, so as to condense the airflow entering the main condensation section 203.

[0099] It should also be noted that when it is determined that the air duct is clogged and the air duct is flushed by the spray assembly 400, the condensation valve 205 is controlled to be closed. That is, the flushing water sprayed by the spray assembly 400 not only plays the role of flushing the dirty blockage, but also replaces the condensed water for condensation.

[0100] Further, in some embodiments, Figure 4 As shown, the spray assembly 400 is disposed on the exhaust port side of the first connecting section 201 , and the spray assembly 400 has a spray head facing one side of the first connecting section 201 , and the spray head is used to spray the interior of the first connecting section 201 .

[0101] In the embodiment of the present application, the spray assembly 400 is arranged on the exhaust port side of the first connecting section 201, and the spray head of the spray assembly 400 is arranged to face the first connecting section 201. On the one hand, the spray head located on the exhaust port side of the first connecting section 201 and facing the first connecting section 201 can more comprehensively rinse the inside of the first connecting section 201 when spraying water. On the other hand, by arranging the spray assembly 400 on the exhaust port side of the first connecting section 201, damage to the spray assembly caused by excessive air flow temperature can be avoided.

[0102] It should be noted that when the airflow in the outer cylinder 100b enters the first connecting section 201, the temperature of the airflow on the air inlet side of the first connecting section 201 is greater than the temperature on the exhaust side of the first connecting section 201. Therefore, by setting the spray assembly 400 on the exhaust side of the first connecting section 201, it is possible to ensure the flushing effect of the spray assembly 400 on the first connecting section 201 while avoiding damage to the spray assembly 400 due to high temperature.

[0103] Further, in some embodiments not shown in the figure, the inner peripheral wall of the first connecting section 201 is formed with a plurality of grooves distributed along the length direction of the first connecting section 201;

[0104] The spraying angle of the spray head facing the first connecting section 201 can be adjusted, and different grooves among the multiple grooves can be sprayed by changing the spraying angle of the spray head.

[0105] In the embodiment of the present application, the spray head of the spray assembly 400 is set to be adjustable. In this way, when the spray assembly 400 is started to flush the inside of the first connecting section 201, the multiple grooves inside the first connecting section 201 can be accurately flushed by adjusting the spray angle of the spray head, thereby flushing away the hair debris accumulated in the grooves, preventing the hair debris from accumulating in the grooves of the first connecting section for a long time and breeding bacteria.

[0106] Further, in some embodiments, Figure 4 As shown, the first connecting section 201 extends along the front-to-back direction of the laundry treatment tub 100;

[0107] The second connecting section 202 extends along the front-to-back direction of the laundry processing tub 100;

[0108] The main condensing section 203 extends along the up-down direction of the laundry processing tub 100 .

[0109] Further, in some embodiments not shown in the figure, the first connecting section 201 forms a downwardly inclined angle;

[0110] A water storage tank is formed at the bottom of the main condensing section 203, and a drain member with a filter screen that can be controlled to open and close is provided at the bottom of the water storage tank;

[0111] The left and right sides of the inner wall surface of the main condensing section 203 are formed with lint guide grooves, and the lint guide grooves are connected to the water storage tank.

[0112] It is worth mentioning that the "left and right sides" in the above-mentioned "litter guide grooves are formed on the left and right sides of the inner wall surface of the main condensation section 203" refers to the perspective of the user facing the clothing inlet 101, that is, from the perspective of the user facing the clothing inlet 101, litter guide grooves are formed on the left and right sides of the main condensation section 203, so that the flushing water mixed with litter can be easily guided into the water storage tank, and the litter in the flushing water can be filtered through the filter in the water storage tank.

[0113] In some embodiments not shown in the figure, the flushing water filtered through the filter can be pumped into the top of the condensation zone again by the water pumping device and flow from the top of the condensation zone to the bottom of the condensation zone again, so as to use the filtered condensed water to re-condense the hot and humid airflow in the condensation zone, thereby improving the utilization rate of the condensed water.

[0114] It should also be explained that the reason why the dandruff guide grooves are arranged on the left and right sides of the inner wall surface of the main condensation section 203 in the embodiment of the present application, but not on the front and rear sides of the inner wall surface of the main condensation section 203, is because the main condensation section 203 has condensation ribs on the two wall surfaces in the front and rear directions. By arranging the dandruff guide grooves on the left and right sides of the inner wall surface of the main condensation section 203, the condensation ribs arranged in the front and rear directions of the main condensation section 203 can be avoided.

[0115] Furthermore, a second aspect of an embodiment of the present application provides a clothing processing device, which includes the drying system provided by the first aspect of the embodiment.

[0116] Furthermore, a third aspect of the embodiment of the present application provides a method for treating dirty and blocked air ducts of a clothes processing device, the method being applied to the clothes processing device provided by the second aspect of the embodiment, the clothes processing device having a drying program;

[0117] Methods for dealing with dirty and blocked air ducts include:

[0118] Under the drying program, a first temperature collected by the first temperature sensor 301 and a second temperature collected by the second temperature sensor 302 are obtained;

[0119] calculating a difference between a first temperature and a second temperature;

[0120] The opening and closing of the spray assembly 400 is controlled according to the difference between the first temperature and the second temperature.

[0121] The method for handling air duct blockage provided in the embodiment of the present application can automatically and timely determine whether dirt blockage occurs inside the first connecting section 201 by acquiring the first temperature collected by the first temperature sensor 301 and the second temperature collected by the second temperature sensor 302 under the drying program, thereby avoiding the first connecting section 201 being blocked for too long and affecting the drying effect of the clothes.

[0122] That is, in the embodiment of the present application, by obtaining the temperature difference between the air inlet side and the air outlet side of the first connecting section 201, it is possible to timely determine whether dirt or blockage occurs inside the first connecting section 201, thereby avoiding the first connecting section 201 being blocked for too long and affecting the drying effect of the clothes.

[0123] It should be noted that the reason why the temperature difference between the air inlet side and the air outlet side of the first connecting section 201 is obtained under the drying program in the embodiment of the present invention is that dirt and blockage are most likely to occur inside the first connecting section 201, and the temperature values ​​obtained at the air inlet side and the air outlet side of the first connecting section 201 are relatively stable and are not easily affected by other components in the clothing processing equipment {other components such as fans, heaters, etc.}, so that when the temperature is obtained at this position, it can accurately reflect whether dirt and blockage occur in the first connecting section 21.

[0124] Further, in some embodiments, the opening and closing of the spray assembly 400 is controlled according to the difference between the first temperature and the second temperature, including:

[0125] If the difference between the first temperature and the second temperature is greater than the first preset temperature difference, the spray assembly 400 is controlled to open;

[0126] If the difference between the first temperature and the second temperature is less than or equal to the first preset temperature difference, the spray assembly 400 is controlled to be closed.

[0127] Further, in some embodiments, if the difference between the first temperature and the second temperature is greater than the first preset temperature difference, the spray assembly 400 is controlled to open, including:

[0128] Controlling the number of times and / or frequency of opening the spray assembly 400 according to the temperature difference between the first temperature and the second temperature;

[0129] The higher the temperature difference between the first temperature and the second temperature, the more serious the dirtiness and blockage of the first connecting section. The number of times the spray component is opened is positively correlated with the temperature difference level, and the frequency of opening the spray component is positively correlated with the temperature difference level.

[0130] That is, the more serious the dirt and blockage inside the first connecting section 201 is, the more times the spray assembly 400 is opened and / or the higher the opening frequency of the spray assembly is, so as to solve the problem of dirt and blockage in the air duct in time.

[0131] Further, in some embodiments, if the difference between the first temperature and the second temperature is greater than the first preset temperature difference and less than or equal to the second preset temperature difference, the temperature difference between the first temperature and the second temperature is at the first level;

[0132] If the difference between the first temperature and the second temperature is greater than the second preset temperature difference and less than or equal to the third preset temperature difference, the temperature difference between the first temperature and the second temperature is at the second level;

[0133] If the difference between the first temperature and the second temperature is greater than a third preset temperature difference, the temperature difference between the first temperature and the second temperature is at a third level;

[0134] Controlling the number of times and / or frequency of opening the spray assembly according to the temperature difference between the first temperature and the second temperature includes:

[0135] If the temperature difference between the first temperature and the second temperature is at the first level, controlling the spray assembly to be turned on m times at the first opening frequency;

[0136] If the temperature difference between the first temperature and the second temperature is at the second level, controlling the spray assembly to be turned on n times at the second opening frequency;

[0137] If the temperature difference between the first temperature and the second temperature is at the third level, the spray assembly is controlled to be turned on q times at the third opening frequency;

[0138] The third start-up frequency is higher than the second start-up frequency, the second start-up frequency is higher than the first start-up frequency, or the third start-up frequency, the second start-up frequency and the first start-up frequency are the same;

[0139] Where 2≤m<n<q.

[0140] Specific, combined Figure 3 As shown, when T0<△T≤T0+i, the number of flushing is a; when T0+i<△T≤T0+j, the number of flushing is b; when T0+j<△T, the number of flushing is c; wherein the single flushing time is 1min, the pause is 10s, and the flow rate is 8L / min; in this way, the hair debris blocked by the internal organs of the first connecting section 201 can be flushed away in time, and the hair debris and dirty blockage can be effectively prevented from agglomerating due to long-term drying, making it more difficult to flush, and thus causing poor drying effect. Among them, i<j, a<b<c, specifically i is 2℃, j is 5℃, a is 2, b is 5, c is 8, T0 is the maximum value of the normal error value, and T0 is 20℃.

[0141] It is worth mentioning that the reason why there is a 10-second interval between two adjacent flushings is to prevent the temperature in the clothes treatment drum from dropping too quickly due to the continuous flushing of the spray component, and to prevent the temperature in the clothes treatment drum from being too low, resulting in a slow temperature rise in the later stage.

[0142] Further, in some embodiments, controlling the opening and closing of the spray assembly according to the difference between the first temperature and the second temperature includes:

[0143] If the difference between the first temperature and the second temperature obtained for w consecutive times is greater than the first preset temperature difference, or if the difference between the first temperature and the second temperature does not meet the requirement within the target time, the spray component is controlled to open;

[0144] Otherwise, the spray assembly is controlled to be closed;

[0145] Where w≥2.

[0146] In the embodiment of the present application, the reason for obtaining multiple temperature difference values ​​when judging whether the first connecting section 201 is dirty or blocked is to make the data more comprehensive and to facilitate the analysis of whether the temperature on the air inlet side and the exhaust port side of the first connecting section 201 has reached a stable state, thereby improving the accuracy of the judgment result.

[0147] Furthermore, in some embodiments, in the drying process, the temperature difference between the air inlet side and the air outlet side of the first connecting section 201 is obtained once every first preset time interval.

[0148] Preferably, in the embodiment of the present invention, the temperature difference between the air inlet side and the air outlet side of the first connection section 201 is obtained once per second. That is, the temperature sensor installed at the front and rear positions of the connection between the rear cylinder of the outer cylinder and the rear air duct {i.e., the condensing air duct} collects the temperature value once per second. If the temperature difference △T between the air inlet side and the air outlet side of the first connection section 201 obtained each time exceeds the first preset temperature difference value T0, and the temperature difference △T detected for five consecutive cycles exceeds the first preset temperature difference value T0 {to eliminate the influence of temperature instability as much as possible and reduce the probability of misjudgment}, it is determined that there is dirt and blockage inside the first connection section 201, wherein the above-mentioned one cycle is 1 minute.

[0149] Preferably, if the temperature difference △T=T1-T2 is greater than T0{T1 is the temperature value collected by the first temperature sensor, T2 is the temperature value collected by the second temperature sensor}, and the temperature difference values ​​collected for five consecutive cycles are all greater than T0, it is determined that there is dirt blockage inside the first connecting section 201, wherein one cycle is 1min; T0 is the maximum value of the normal error value, and T0 is 20°C. That is, the temperature difference values ​​calculated after 300 consecutive collections are all greater than T0, and then it is determined that there is dirt blockage inside the first connecting section 201, so as to ensure that the stability of the temperature value is not accidental, thereby helping to reduce the misjudgment rate.

[0150] Further, in some embodiments, the drying program includes a drying and dehydration stage, a drying weighing stage, a drying heating stage, a drying dryness determination stage, and a drying cooling stage, which are performed in sequence;

[0151] Under the drying program, a first temperature collected by a first temperature sensor and a second temperature collected by a second temperature sensor are obtained; and a difference between the first temperature and the second temperature is calculated;

[0152] Controlling the opening and closing of the spray assembly according to the difference between the first temperature and the second temperature includes:

[0153] In the drying determination stage of the drying program, the first temperature and the second temperature are obtained and the difference between the two is calculated, and the opening and closing of the spray component is controlled according to the difference between the first temperature and the second temperature.

[0154] The reason why the temperature difference between the air inlet side and the air outlet side of the first connecting section 201 is obtained in the drying judgment stage in the embodiment of the present invention is that the water inlet and temperature conditions in this stage are relatively stable, which can greatly reduce the probability of temperature detection misjudging dirt and blockage.

[0155] It should be noted that the heating stage is the process of turning on the electric heating and the fan to achieve rapid accumulation of heat; the drying dryness judgment stage {may include an additional drying dryness judgment stage} is the process of turning on the electric heating and the fan, and introducing condensed water, and is a process of balancing the evaporation and condensation amounts; the drying and cooling stage is the process of turning off the electric heating, turning on the fan, and introducing condensed water, and is a process of rapidly lowering the temperature inside the drum.

[0156] Furthermore, in some embodiments, the above-mentioned clothes processing device is a drum-type clothes processing device. Preferably, the drum-type clothes processing device is a drum-type washer-dryer or a drum-type clothes dryer.
