[0002] With the improvement of people's living standards and the acceleration of work pace, the technical development direction of the dryer industry is increasingly tending towards being smarter, more energy-efficient and more hygienic. The problem of lint blocking the dryer condenser is becoming more and more prominent. In the relevant technology, a filter is generally set at the front end of the condenser to filter the lint in the circulating air to reduce the lint blocking the condenser.

[0003] The solution of filtering lint through a filter still has defects: the filter does not filter the lint in the circulating air thoroughly. After long-term use, the lint will still clog the surface of the condenser. The user cannot determine whether the condenser is blocked and can only adopt regular cleaning methods. It is impossible to clean the condenser in time when it is blocked; and when the condenser is blocked by lint, the condensation efficiency is reduced, and more water vapor in the circulating air enters the inner drum again to contact the clothes being dried, prolonging the drying time; furthermore, the accumulation of lint will breed bacteria, posing a threat to human health.

[0059] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0060] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0061] In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0063] Refer to the following Figures 1 to 10 To describe the condenser blockage detection method, device, clothing processing equipment and computer-readable storage medium provided according to some embodiments of the present application.

[0064] An embodiment of the first aspect of the present application provides a condenser blockage detection method. Figure 1 A schematic diagram of an implementation flow of the condenser blockage detection method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes Figure 1 Steps S101 to S104 shown below are combined Figure 1 Each step is explained.

[0065] Step S101, obtaining the initial temperature of the gas in the clothes processing device and the weight of the load in the barrel of the clothes processing device.

[0066] The condenser blockage detection method of the embodiment of the present application is applied to a clothing processing device, which can be a washing and drying machine, a clothes dryer, or other equipment with a condensing function. In the embodiment of the present application, the clothing processing device is described by taking a clothes dryer as an example. Unless otherwise specified below, the clothing processing device refers to a clothes dryer.

[0067] When the dryer is in operation, the gas in the drying channel enters the barrel from the air inlet of the barrel and exchanges heat with the wet clothes in the barrel, which not only removes the moisture in the wet clothes, but also removes the lint and other blockages in the barrel that may cause the condenser to be blocked. In order to prevent the lint and other blockages from clogging the condenser, a filter is generally provided at the air outlet. The gas with blockages discharged from the barrel outlet passes through the filter, and most of the blockages in the gas are filtered out. A small part of the blockages passes through the mesh or assembly gap of the filter, or the blockages enter and accumulate in the condenser due to improper installation of the filter or during disassembly, resulting in reduced condensation efficiency of the condenser and prolonged drying time of the dryer.

[0068] Without adding a detection device, the related technology cannot automatically detect the degree of blockage of the condenser, and the user can only disassemble the dryer regularly to clean the blockage accumulated in the condenser. In view of this problem, the embodiment of the present application provides a solution for detecting the degree of blockage of the condenser. First, after determining that the dryer has entered the drying process, the initial temperature of the gas in the dryer and the weight of the load in the dryer barrel are obtained. When the drying process just begins, the heating device has not yet been turned on, and the initial temperature of the gas in the dryer is equal to the ambient temperature outside the barrel. Different ambient temperatures have different effects on the condensation capacity of the condenser. The load here includes not only clothes, but also the moisture in the clothes.

[0069] Step S102: determining a reference condensing efficiency of the condenser based on the initial temperature and the weight of the load.

[0070] In the case where there is no blockage in the condenser, after the temperature and load weight are determined, the condensation efficiency of the condenser is fixed, and this condensation efficiency is called the reference condensation efficiency. Since the main stage of the dryer drying clothes is after the drying process enters the drying stable stage, before the dryer gas temperature reaches the preset temperature range, the gas temperature is low, and the moisture carried away from the clothes to be dried is limited. The amount of water condensed by the condenser can be ignored. At this time, even if there is a blockage, the impact on the condensation efficiency is very small. Based on this, in the embodiment of the present application, the condensation efficiency of the condenser will be determined based on the initial temperature and the weight of the load, which is considered to be the reference condensation efficiency of the condenser in the absence of blockage.

[0071] In the embodiment of the present application, a correspondence table of each temperature value within the general ambient temperature range, each load weight within the load range and the reference condensing efficiency of the condenser can be determined in advance according to experiments, and the correspondence table is stored in the memory of the dryer. After the initial temperature and the load weight are obtained, the correspondence table is queried according to the initial temperature and the load weight to obtain the reference condensing efficiency of the condenser.

[0072] Step S103, obtaining the amount of condensed water of the condenser within a first period of time in the drying stabilization phase, and determining the actual condensation efficiency of the condenser based on the amount of condensed water.

[0073] In the embodiment of the present application, according to the temperature of the gas in the dryer during the drying process, the drying process can be divided into a preheating stage, a drying stabilization stage and a cooling stage, wherein the preheating stage is a stage in which the temperature in the barrel is lower than the lower limit of the preset temperature range, the drying stabilization stage is a stage in which the temperature in the barrel is maintained between the lower limit and the upper limit of the preset temperature range, and the cooling stage is a stage in which the temperature in the barrel drops from the lower limit of the preset temperature range to a safe temperature that will not harm the user. Among them, the preheating stage can be divided into a cold wind stage and a warming stage. The heating device is not turned on during the cold wind stage. After the cold wind stage ends, the heating device continues to operate at a constant power during the warming stage and the drying stabilization stage. During the warming stage, due to the short startup time of the entire drying system and the influence of the ambient temperature, the precipitation rate of condensed water is unstable. After running for a period of time, it enters the drying stabilization stage, the operation of the entire drying system tends to be stable, the temperature remains basically unchanged, and the precipitation rate of condensed water remains stable until the clothes are dried. When the clothes are dried, it is determined that the drying process enters the cooling stage, the heating device is turned off to stop heating, and the gas temperature in the dryer gradually decreases. It can be seen that in the entire drying process, the dryer can play the best drying effect in the stable drying stage. Therefore, the condensing efficiency of the condenser in the stable drying stage is taken as its actual working efficiency.

[0074] Here, the first duration may be a period of time when the drying process is in the drying stable stage. Exemplarily, when it is determined that the drying process enters the drying stable stage, timing is started, and when the timing duration reaches the first duration, the amount of condensed water in the condenser is obtained. In actual implementation, the amount of condensed water in the condenser can be obtained based on a water level detection device, which can be a water level sensor or other device capable of measuring water volume.

[0075] In one implementation, the first time length may be a unit time, and when the drying process is in the drying stable stage, the actual condensation efficiency is determined according to the amount of condensed water condensed in the unit time. In another implementation, the first time length may be any preset time length that is greater than the unit time and not greater than the total time length of the drying stable stage. Compared with the first implementation of determining the actual condensation efficiency according to the amount of condensed water in the unit time, the second implementation is adopted to obtain the amount of water condensed in the first time length that is longer than the unit time, and the detected water amount is more accurate, so that the determined actual condensation efficiency is more accurate.

[0076] Step S104, determining the blockage degree of the condenser according to the reference condensation efficiency and the actual condensation efficiency.

[0077] Since the blockage in the condenser affects the condensation efficiency of the condenser, the actual condensation efficiency of the condenser is less than or equal to the reference condensation efficiency. After determining the reference condensation efficiency and the actual condensation efficiency, the degree of blockage of the condenser can be determined according to the deviation between the actual condensation efficiency and the reference condensation efficiency. In this way, blockage detection can be achieved without adding other detection devices. Users can determine whether it is necessary to clean the blockage in the condenser according to the degree of blockage. After determining that the condenser is blocked, it can be cleaned in time to ensure that the condenser works in an unblocked state, thereby shortening the drying time and avoiding contamination of clothes by blockages, making the clothing processing equipment more energy-efficient and more hygienic.

[0078] The condenser blockage detection method provided in the embodiment of the present application is applied to a clothing processing device, and the method includes: obtaining the initial temperature of the gas in the clothing processing device and the weight of the load in the barrel of the clothing processing device; determining the reference condensation efficiency of the condenser based on the initial temperature and the weight of the load; obtaining the amount of condensed water in the condenser within the first time period of the drying stabilization phase, and determining the actual condensation efficiency of the condenser based on the amount of condensed water; determining the blockage degree of the condenser according to the reference condensation efficiency and the actual condensation efficiency. In this way, blockage detection can be achieved without adding other detection devices. The user can determine whether it is necessary to clean the blockage of the condenser according to the blockage degree. After determining that the condenser is blocked, it can be cleaned in time to ensure that the condenser works in an unblocked state, thereby shortening the drying time and avoiding the blockage from contaminating the clothes, making the clothing processing device more energy-efficient and more hygienic.

[0079] In some embodiments, the above Figure 1 In the embodiment shown, step S101 of "obtaining the initial temperature of the clothes processing device and the weight of the load in the barrel of the clothes processing device" can be performed as follows: Figure 2 Steps S201 to S204 are implemented as shown below. Figure 2 Explain each step:

[0080] Step S201, detecting the temperature of the gas in the clothes processing device to obtain an initial temperature.

[0081] In the embodiment of the present application, after entering the drying process, the temperature of the gas in the dryer can be immediately detected to obtain the initial temperature. Although this method can immediately obtain the initial temperature, the initial temperature may deviate from the actual ambient temperature. In order to obtain a more accurate ambient temperature, in the embodiment of the present application, after entering the drying process, the heating device is not turned on temporarily, the barrel body is controlled to rotate, and the fan is turned on first, so that the gas outside the barrel body and the gas inside the barrel body circulate, that is, when the drying process is in the cold air stage, the temperature of the gas inside the barrel body is detected to obtain the initial temperature. The initial temperature obtained at this time can be considered as the ambient temperature outside the barrel body, which is closer to the actual temperature of the clothes to be dried.

[0082] In practical applications, one implementation method for obtaining the initial temperature may be: determining that the drying process has begun, controlling the motor of the clothes processing device to start to drive the barrel to rotate without starting the heating device; determining that the barrel has rotated for a second time, detecting the temperature of the gas in the clothes processing device to obtain a first temperature, and determining the first temperature as the initial temperature. In this implementation method, after the barrel rotates for the second time, the temperature of the gas in the dryer only needs to be detected once to obtain the initial temperature. The advantage is that the number of detections is small, but one detection may not be accurate enough to ensure the accuracy of the initial temperature.

[0083] Another implementation method for obtaining the initial temperature may be: determining that the drying process has begun, controlling the motor of the clothing treatment device to start to drive the barrel to rotate without starting the heating device; detecting the temperature of the gas in the clothing treatment device multiple times within the second time period to obtain multiple temperature values; and determining the average of the multiple temperature values ​​as the initial temperature. In this implementation method, after the barrel rotates, the temperature of the gas in the barrel is detected multiple times within the second time period to obtain multiple temperature values, and the initial temperature is determined based on the multiple temperature values, for example, the average of the multiple temperature values ​​is used as the initial temperature. Although this implementation method requires multiple detections, it can ensure the accuracy of the initial temperature, thereby ensuring the accuracy of the reference condensation efficiency.

[0084] In the embodiment of the present application, the second time length can be set to any value between 30s (seconds) and 5min (minutes), for example, the second time length is set to 3min. The device for detecting the temperature of the gas can be a temperature detection device set in the barrel, and the temperature detection device can be a temperature sensor.

[0085] Step S202, controlling a heating device of the clothes processing equipment to start heating the gas.

[0086] After the initial temperature is obtained, the heating device of the dryer is controlled to start and heat the gas in the barrel, and the temperature of the gas in the barrel begins to gradually increase.

[0087] Step S203, detecting whether the temperature of the gas reaches a preset temperature value.

[0088] As the heating device is started, the temperature of the gas in the barrel shows an upward trend, and the temperature rise rate is related to the amount of clothes in the barrel. For example, if the amount of clothes in the barrel is large, the temperature rises slowly, and vice versa. In this way, the weight of the load can be indirectly obtained based on the temperature rise rate. When it is detected that the temperature of the gas reaches the preset temperature value, step S204 is entered; when it is detected that the temperature of the gas does not reach the preset temperature value, step S203 is continued.

[0089] In an embodiment of the present application, during the drying stabilization stage, the temperature inside the barrel is maintained within a preset temperature range, which can be set to any range between 50°C (degrees Celsius) and 80°C. For example, the preset temperature range is set to 55°C to 60°C. Generally, fabrics of different materials can withstand different drying temperatures. The preset temperature range can be set to multiple ranges according to the different materials of the clothes. When selecting the drying function, the user selects the material of the clothes to be dried and sets the corresponding preset temperature range.

[0090] The above-mentioned preset temperature value can be set to a value equal to the lower limit of the preset temperature range (i.e., the preset temperature threshold is 55° C.). In some alternative embodiments, the preset temperature value can also be set to a value lower than the preset temperature threshold, for example, 50° C., so that the weight of the load can be obtained within a certain range of temperature rise.

[0091] Step S204, obtaining the weight of the load in the barrel of the clothing processing device.

[0092] The weight of the load can be determined based on the initial temperature, the preset temperature value and the heating time. This can be achieved as follows: when it is detected that the temperature of the gas reaches the preset temperature value, the heating time of the heating device is obtained; and based on the heating time, the initial temperature and the preset temperature value, the weight of the load in the barrel is determined.

[0093] In the embodiment of the present application, the corresponding relationship table of each temperature value within the general ambient temperature range, each load weight within the load range, the preset temperature value and the heating time can be determined in advance according to experiments. For example, the experimental measurement is: the barrel carries a 5kg (kilogram) load, and it takes 20 minutes to heat the gas in the barrel from the ambient temperature of 25°C to 60°C; the barrel carries a 6kg (kilogram) load, and it takes 25 minutes to heat the gas in the barrel from the ambient temperature of 25°C to 60°C, etc., and these experimental measurement values ​​are stored in the memory of the dryer in the form of a corresponding relationship table. After obtaining the initial temperature, the preset temperature value and the heating time, the corresponding relationship table is queried according to the initial temperature, the preset temperature value and the heating time to obtain the weight of the load in the barrel.

[0094] In some embodiments, the above Figure 1 In the embodiment shown, step S103 of "obtaining the amount of condensed water of the condenser during the first time period of the drying stabilization phase, and determining the actual condensation efficiency of the condenser based on the amount of condensed water" can be performed as follows: Figure 3 Steps S301 to S303 shown in the figure are implemented, and the following is combined with Figure 3 Explain each step:

[0095] Step S301, determining whether the time for the gas temperature to reach a preset temperature range reaches a first time.

[0096] When the drying process is in the stable drying stage for a first time period, that is, when the temperature of the gas in the barrel reaches the preset temperature range for a first time period, enter step S302; when the drying process is in the stable drying stage for a first time period, that is, when the temperature of the gas in the barrel reaches the preset temperature range for a first time period, continue the drying process and return to step S301 to re-acquire the time for the gas temperature to reach the preset temperature range.

[0097] In the embodiment of the present application, the first duration can be set to any value between 15 minutes and 35 minutes, for example, set to 25 minutes.

[0098] Step S302, detecting the amount of condensed water in the condenser within a first period of time.

[0099] When the drying process is in the stable drying stage, the temperature of the gas is maintained within the preset temperature range. The hot dry gas within the preset temperature range exchanges heat with the clothes to be dried, takes the moisture in the clothes out of the barrel, forms wet and cold gas, and condenses the moisture in the wet and cold gas through the condenser, and re-enters the barrel, and the cycle continues. In the process of drying the clothes to be dried, the condenser condenses condensed water. When the duration of the drying process in the stable drying stage reaches the first duration, that is, when the duration of the gas temperature reaching the preset temperature range reaches the first duration, the amount of water condensed by the condenser within the first duration is detected by the water level sensor in the dryer to obtain the amount of condensed water.

[0100] Step S303: determining the actual condensation efficiency of the condenser according to the first time period and the amount of condensed water.

[0101] In the embodiment of the present application, a correspondence table between the preset temperature range, the weight of each load in the load range, the duration, the amount of condensed water and the actual condensing efficiency of the condenser can be determined in advance according to experiments, and the correspondence table is stored in the memory of the dryer. After the load weight, the first duration and the amount of condensed water are obtained according to the above step S204, the correspondence table is queried to obtain the actual condensing efficiency of the condenser.

[0102] In an embodiment of the present application, the actual condensation efficiency of the condenser can be determined based on parameters such as the amount of condensed water and the weight of the load within the first period of time during the drying process, thereby preparing for the subsequent determination of the degree of blockage of the condenser based on the actual condensation efficiency and the reference condensation efficiency.

[0103] In some embodiments, the above Figure 1 In the embodiment shown, step S104 "determining the blockage degree of the condenser according to the reference condensation efficiency and the actual condensation efficiency" can be performed as follows: Figure 4 Steps S401 to S404 are implemented as shown below. Figure 4 Explain each step:

[0104] Step S401, determining a condensation efficiency difference according to a reference condensation efficiency and an actual condensation efficiency.

[0105] Here, the reference condensation efficiency is recorded as E1, the actual condensation efficiency is recorded as E2, the condensation efficiency difference is recorded as ΔE, and the condensation efficiency difference is calculated according to ΔE=E1-E2.

[0106] Step S402, determining whether the condensation efficiency difference is greater than a preset efficiency threshold.

[0107] When the condensation efficiency difference is greater than the preset efficiency threshold, it indicates that the difference between the actual condensation efficiency and the reference condensation efficiency is large, and it is considered that there are many blockages, which have a great impact on the condensation efficiency of the condenser, and the process goes to step S403; when the condensation efficiency difference is less than or equal to the preset efficiency threshold, it indicates that the difference between the actual condensation efficiency and the reference condensation efficiency is small, and it is considered that there are few blockages, which have a small impact on the condensation efficiency of the condenser, and the process goes to step S404.

[0108] Step S403: determining the blockage degree of the condenser as severe blockage.

[0109] Step S404: determining the blockage degree of the condenser as slight blockage.

[0110] In an embodiment of the present application, the difference between the reference condensation efficiency and the actual condensation efficiency is compared with a preset efficiency threshold. When the difference between the reference condensation efficiency and the actual condensation efficiency is greater than the preset efficiency threshold, it is determined that the degree of blockage of the condenser is severe and needs to be cleaned; when the difference between the reference condensation efficiency and the actual condensation efficiency is less than or equal to the preset efficiency threshold, it is determined that the degree of blockage of the condenser is slight and no cleaning is required.

[0111] In other embodiments, the blockage degree of the condenser can also be determined according to the ratio of the difference between the actual condensation efficiency and the reference efficiency. In this case, the blockage degree of the condenser can be determined as follows: the condensation efficiency ratio is determined according to the actual condensation efficiency and the reference condensation efficiency; when the condensation efficiency ratio is less than the preset ratio threshold, the blockage degree of the condenser is determined as severe blockage; when the condensation efficiency ratio is greater than or equal to the preset ratio threshold, the blockage degree of the condenser is determined as slight blockage. For example, the preset ratio threshold is 0.7. When the condensation efficiency ratio is 0.8, it indicates that the actual condensation efficiency reaches 80% of the reference condensation efficiency. At this time, it is considered that there are few blockages, the blockage degree of the condenser is slight, and no cleaning is required; when the condensation efficiency ratio is 0.5, it indicates that the actual condensation efficiency is only 50% of the reference condensation efficiency. At this time, it is considered that there are many blockages, the blockage degree of the condenser is severe, and cleaning is required.

[0112] In the above Figure 1 On the basis of the embodiment shown, the embodiment of the present application further provides a condenser blockage detection method, which is applied to a clothes processing device. Figure 5 Another implementation flow diagram of the condenser blockage detection method provided in the embodiment of the present application is as follows: Figure 5 As shown, the condenser blockage detection method comprises the following steps:

[0113] Step S501, obtaining the initial temperature of the gas in the clothes processing device and the weight of the load in the barrel of the clothes processing device.

[0114] In the embodiment of the present application, steps S501 to S504 are Figure 1 In the embodiment shown, steps S101 to S104 correspond to each other. The implementation methods and effects of steps S501 to S504 can be found in the above Figure 1 A detailed description of the illustrated embodiments.

[0115] Step S502: determining a reference condensing efficiency of the condenser based on the initial temperature and the weight of the load.

[0116] Step S503, obtaining the amount of condensed water of the condenser within a first period of time in the drying stabilization phase, and determining the actual condensation efficiency of the condenser based on the amount of condensed water.

[0117] Step S504: determining the blockage degree of the condenser according to the reference condensation efficiency and the actual condensation efficiency.

[0118] Step S505, detecting the humidity inside the barrel to obtain a first humidity value.

[0119] After determining the blockage degree of the condenser, the dryer continues the drying process. During the drying process, the humidity in the barrel is detected by a humidity detection device in the dryer, that is, the humidity of the clothes in the barrel is detected to obtain a first humidity value. The humidity detection device may be a humidity sensor.

[0120] Step S506, determining whether the first humidity value is less than a drying humidity threshold.

[0121] When the first humidity value is less than the drying humidity threshold, it indicates that the clothes in the barrel have been dried, and step S507 is entered at this time; when the first humidity value is greater than or equal to the drying humidity threshold, it indicates that the humidity of the clothes in the barrel is still relatively high and has not been dried yet, and the drying process continues, and step S505 is returned to re-acquire the first humidity value.

[0122] Step S507, determining to end the drying process.

[0123] Step S508, determining whether the blockage degree of the condenser is severe.

[0124] When it is determined according to step S504 that the blockage degree of the condenser is severe, it is necessary to output a prompt message to prompt the user to clean the blockage in the condenser in time, and then enter step S509; when it is determined according to step S504 that the blockage degree of the condenser is slight, no cleaning is required, and enter step S510 to end the program.

[0125] Step S509, controlling the alarm device of the clothes processing equipment to output prompt information.

[0126] The prompt information here is used to prompt the user to clean the condenser so that the user can clear the blockage in the condenser in time.

[0127] Step S510, end.

[0128] In the embodiment of the present application, after the drying process is completed, when the blockage degree of the condenser is slightly blocked, the dryer enters a standby state without outputting a prompt message; when the blockage degree of the condenser is severely blocked, the dryer enters a standby state, and the alarm device of the dryer outputs a prompt message, which may be a display indication code, or the condenser blockage indicator light may be on, or the alarm device may emit an alarm sound, or when the dryer and the user terminal are able to transmit information, the prompt message may be a prompt message sent by the dryer to the user terminal.

[0129] In other embodiments, after the drying process is completed, when the blockage degree of the condenser is slightly blocked, the dryer enters a standby state, and the alarm device of the dryer can also output a prompt message to remind the user that the blockage degree is slightly blocked, so that the user can know the blockage degree of the condenser after each use of the dryer.

[0130] The condenser blockage detection method provided in the embodiment of the present application, after detecting the blockage degree of the condenser, when it is determined that the blockage degree of the condenser is severe, further outputs a prompt message after the drying program is completed, so that the user is promptly informed that the condenser is blocked, so that the blockage in the condenser can be cleaned in time, ensuring that the condenser works in an unblocked state, shortening the drying time and improving the drying effect.

[0131] On the basis of the above embodiments, the present application further provides a condenser blockage detection method, which is applied to a clothes processing device. Figure 6 A schematic diagram of another implementation flow of the condenser blockage detection method provided in the embodiment of the present application is as follows: Figure 6 As shown, the condenser blockage detection method comprises the following steps:

[0132] Step S601, determining to enter the drying process, controlling the motor of the clothing processing device to start to drive the barrel to rotate, and controlling the heating device of the clothing device to not work.

[0133] Here, the fan of the clothes processing device can also be started to promote the air in the barrel to circulate faster. At this time, the heating device of the clothes processing device is not started temporarily, and it is started again after the initial temperature is obtained.

[0134] Step S602: Detect the temperature of the gas in the clothes processing device multiple times within the second time period to obtain multiple temperature values.

[0135] During the second time period, the drying process is in the cold wind stage.

[0136] Step S603: determining an average value of the plurality of temperature values ​​as the initial temperature of the gas in the clothes treating device.

[0137] In an embodiment of the present application, after the barrel body rotates, the temperature of the gas in the barrel body is detected multiple times within the second time period to obtain multiple temperature values, and the initial temperature is determined based on the multiple temperature values. For example, the average value of the multiple temperature values ​​is used as the initial temperature. Although this implementation method requires multiple detections, it can ensure the accuracy of the initial temperature, thereby ensuring the accuracy of the reference condensation efficiency.

[0138] In some other embodiments, the above steps S602 and S603 may be replaced by steps S602' and S603':

[0139] Step S602', determining whether the duration of the barrel body rotation reaches a second duration.

[0140] When the barrel body rotates for a second time, it indicates that the temperature of the gas inside the barrel body is consistent with the ambient temperature outside the barrel body, and step S603' is entered at this time; when the barrel body rotates for a second time, step S602' is continued.

[0141] Step S603', detecting the temperature of the gas in the clothes processing device to obtain a first temperature, and determining the first temperature as the initial temperature of the gas.

[0142] In this embodiment, after the barrel rotates for the second time, the temperature of the gas in the clothing processing device only needs to be detected once to obtain the initial temperature. The advantage is that the number of detections is small, but one detection may not be accurate enough to ensure the accuracy of the initial temperature.

[0143] Step S604, controlling the heating device of the clothes processing equipment to start to heat the gas.

[0144] After obtaining the initial temperature, the heating device is controlled to start and begin to heat the gas in the barrel. The gas temperature in the barrel begins to gradually increase. At this time, the drying process is in the heating stage.

[0145] Step S605, determining whether the temperature of the gas reaches a preset temperature value.

[0146] When it is detected that the temperature of the gas reaches the preset temperature value, the process proceeds to step S606 ; when it is detected that the temperature of the gas does not reach the preset temperature value, the process continues to execute step S605 .

[0147] Step S606, obtaining the heating time of the heating device.

[0148] Step S607, determining the weight of the load in the barrel according to the heating time, the initial temperature and the preset temperature value.

[0149] In the embodiment of the present application, a corresponding relationship table of each temperature value within the general ambient temperature range, each load weight within the load range, a preset temperature value and a heating time can be determined in advance according to experiments, and these experimental measurement values ​​are stored in the memory of the clothing processing device in the form of a corresponding relationship table. After obtaining the initial temperature, the preset temperature value and the heating time, the corresponding relationship table is queried according to the initial temperature, the preset temperature value and the heating time to obtain the weight of the load in the barrel.

[0150] Step S608: determining a reference condensing efficiency of the condenser based on the initial temperature and the weight of the load.

[0151] In the above correspondence table, the correspondence between each temperature value within the general ambient temperature range, each load weight within the load range and the reference condensing efficiency of the condenser determined in advance according to experiments can also be stored. After obtaining the initial temperature and the load weight, the correspondence table is queried to obtain the reference condensing efficiency of the condenser.

[0152] Step S609, determining whether the temperature of the gas reaches a preset temperature range.

[0153] When it is detected that the temperature of the gas reaches the preset temperature threshold, it is determined that the temperature of the gas reaches the preset temperature range, and step S610 is entered; when the temperature of the gas does not reach the preset temperature, it is determined that the temperature of the gas does not reach the preset temperature range, and step S609 is continued. The preset temperature threshold here is the lower limit of the preset temperature range, and the above preset temperature value is less than or equal to the preset temperature threshold.

[0154] Step S610, determining whether the time for the gas temperature to reach the preset temperature range reaches a first time.

[0155] When the drying process is in the stable drying stage for a first time period, that is, when the temperature of the gas in the barrel reaches the preset temperature range for a first time period, enter step S611; when the drying process is in the stable drying stage for a first time period, that is, when the temperature of the gas in the barrel reaches the preset temperature range for a first time period, the drying process is continued, and the process returns to step S609 to re-acquire the time for the temperature of the gas to reach the preset temperature range.

[0156] Step S611, obtaining the amount of condensed water in the condenser within a first time period.

[0157] Here, after determining that the duration of the drying process in the drying stable stage reaches the first duration, the amount of water condensed by the condenser within the first duration can be detected by a water level sensor to obtain the amount of condensed water.

[0158] Step S612: determining the actual condensation efficiency of the condenser according to the first time period and the amount of condensed water.

[0159] In the above correspondence table, the correspondence between the preset temperature range, the load weights within the load range, the duration, the condensed water volume and the actual condensing efficiency of the condenser determined in advance according to experiments can also be stored. After obtaining the first duration and the condensed water volume, the correspondence table is queried to obtain the actual condensing efficiency of the condenser.

[0160] Step S613: determining a condensation efficiency difference according to the reference condensation efficiency and the actual condensation efficiency.

[0161] Here, the reference condensation efficiency is recorded as E1, the actual condensation efficiency is recorded as E2, the condensation efficiency difference is recorded as ΔE, and the condensation efficiency difference is calculated according to ΔE=E1-E2.

[0162] Step S614, determining whether the condensation efficiency difference is greater than a preset efficiency threshold.

[0163] When the condensation efficiency difference is greater than the preset efficiency threshold, it indicates that the difference between the actual condensation efficiency and the reference condensation efficiency is large, and it is considered that there are many blockages, which have a great impact on the condensation efficiency of the condenser, and the process goes to step S615; when the condensation efficiency difference is less than or equal to the preset efficiency threshold, it indicates that the difference between the actual condensation efficiency and the reference condensation efficiency is small, and it is considered that there are few blockages, which have a small impact on the condensation efficiency of the condenser, and the process goes to step S616.

[0164] Step S615, determining the blockage degree of the condenser as severe blockage.

[0165] After determining the blockage degree of the condenser, proceed to step S617 to continue the drying process.

[0166] Step S616, determining the blockage degree of the condenser as slight blockage.

[0167] Step S617, detecting the humidity inside the barrel to obtain a first humidity value.

[0168] After determining the blockage degree of the condenser, the clothes processing device continues the drying process. During the drying process, the humidity in the barrel is detected by the humidity detection device in the clothes processing device, that is, the humidity of the clothes in the barrel is detected to obtain a first humidity value.

[0169] Step S618, determining whether the first humidity value is less than a drying humidity threshold.

[0170] When the first humidity value is less than the drying humidity threshold, it indicates that the clothes in the barrel have been dried, and step S619 is entered at this time; when the first humidity value is greater than or equal to the drying humidity threshold, it indicates that the humidity of the clothes in the barrel is still relatively high and has not been dried yet, and the drying process continues, and returns to step S617 to re-acquire the first humidity value.

[0171] Step S619, determining to end the drying process.

[0172] Step S620, determining whether the blockage degree of the condenser is severe.

[0173] When it is determined according to step S615 that the blockage degree of the condenser is severe, it is necessary to output a prompt message to prompt the user to clean the blockage in the condenser in time and enter step S621; when it is determined according to step S616 that the blockage degree of the condenser is slight, no cleaning is required and enter step S622.

[0174] Step S621, controlling the alarm device of the clothes processing equipment to output prompt information.

[0175] The prompt information here is used to prompt the user to clean the condenser so that the user can clear the blockage in the condenser in time.

[0176] Step S622, end.

[0177] The condenser blockage detection method provided in the embodiment of the present application determines the reference condensation efficiency of the condenser according to the ambient temperature and the weight of the load in the barrel of the clothing processing equipment after the clothing processing equipment determines that it has entered the drying process; after entering the drying stabilization stage, the actual condensation efficiency of the condenser is determined according to the amount of water condensed by the condenser within the first time period, and the blockage degree of the condenser is determined by comparing the reference condensation efficiency and the actual condensation efficiency. When the blockage degree is severe, a prompt message is output. In this way, blockage detection can be achieved without adding other detection devices. The user can determine whether the blockage of the condenser needs to be cleaned according to the blockage degree. When the condenser is blocked, the blockage can be cleaned in time to ensure that the condenser works in an unblocked state, thereby shortening the drying time and avoiding contamination of clothes by blockage, making the clothing processing equipment more energy-efficient and more hygienic.

[0178] The embodiment of the present application further provides a condenser blockage detection method, which is applied to a household appliance with a steam generator. The household appliance in the embodiment of the present application is described by taking a clothes dryer as an example.

[0179] With the improvement of people's living standards and the acceleration of the pace of work, the technical development direction of the dryer industry is increasingly tending towards being smarter, more energy-efficient and more hygienic. The problem of detecting the lint blockage of the dryer condenser is becoming more and more prominent. The current existing technical solutions generally reduce the lint blockage of the condenser by setting a filter at the front end of the condenser to filter the lint in the circulating air and inform the user to clean the condenser regularly. There are two disadvantages in the existing technical solutions. One is that the filter does not filter the lint in the circulating air thoroughly. After long-term use, the lint will block the surface of the condenser. The second is that there is no detection and no reminder to the user after the condenser is blocked, resulting in the user not being able to clean it in time. After the condenser is blocked by lint, the condensation efficiency is reduced, and more water vapor in the circulating air enters the clothes that need to be dried again, resulting in a longer drying time, and the accumulation of lint breeds bacteria and contaminates the clothes.

[0180] The embodiment of the present application provides a solution for detecting condenser blockage, which can detect whether the condenser is blocked in real time and remind the user to clean the condenser in time, thereby shortening the drying time, avoiding lint contamination of clothes, and being more energy-saving and hygienic.

[0181] Figure 7 A schematic diagram of the composition structure of a clothes dryer provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the dryer 70 includes a condenser blockage detection device 71, a heating device 72, a barrel 73, a humidity detection device 74, a temperature detection device 75, a condenser 76, a motor 77 and a water level detection device 78.

[0182] Among them, the heating device 72 is arranged in the drying tunnel for heating the gas in the dryer 70; the barrel 73 is provided with an air outlet 731 and an air inlet 732 for accommodating the clothes to be dried; the humidity detection device 74 is arranged in the barrel 73 for detecting the humidity of the clothes to be dried; the temperature detection device 75 is arranged in the drying tunnel for detecting the temperature of the gas in the dryer; the condenser 76 is arranged at the lower end of the barrel 73 for condensing the gas in the dryer; the motor 77 is arranged at the lower end of the barrel 73 for driving the barrel 73 to rotate; the water level detection device 78 is arranged at the water outlet of the condenser 76 (not shown in the figure) for detecting the amount of water condensed by the condenser 76; the condenser blockage detection device 71 is used to control the heating device 72, the barrel 73, the humidity detection device 74, the temperature detection device 75, the condenser 76, the motor 77 and the water level detection device 78 to detect the degree of blockage of the condenser.

[0183] In the embodiment of the present application, the humidity detection device 74, the temperature detection device 75 and the water level detection device 78 can be sensors, such as humidity sensors, temperature sensors and water level sensors, respectively. The water level sensor can be a sensor that continuously acquires data, or a water level switch that sets an on / off threshold.

[0184] In the present application embodiment, Figure 7 As shown, the dryer 70 further includes a filter 79, which is disposed between the air outlet 731 of the barrel 73 and the condenser 76, and filters the gas discharged from the air outlet 731 that contains lint and the like that may clog the condenser, thereby reducing the amount of clogs that enter the condenser.

[0185] When the clothes dryer is working, the circulating air is heated by the heater module and then exchanges heat with the wet clothes inside the inner drum module (i.e., the barrel body 73). After the circulating air exchanges heat with the clothes, it will carry some lint. The lint filter module (i.e., the filter 79) can filter out most of the lint in the air, but some lint passes through the mesh of the lint filter module or the assembly gap and continues to enter the condenser module and accumulates on it. The temperature sensor module detects the temperature of the circulating air in real time. The circulating air condenses some condensed water in the condenser module, and the water level sensor module detects the amount of condensed water.

[0186] Figure 8 A schematic diagram of another implementation flow of the condenser blockage detection method provided in an embodiment of the present application is shown in FIG. Fig. 9 The curve diagram of the corresponding relationship between the working time of the clothes dryer during the drying process and the gas temperature in the barrel provided in the embodiment of the present application is shown below in combination with Figure 8 and Fig. 9 The condenser blockage detection method provided in the embodiment of the present application is described.

[0187] Step S801, the clothes drying process starts.

[0188] Step S802: the motor drive module is started.

[0189] The motor drive module is the above-mentioned motor 77. When the clothes drying program starts, the motor drive module starts to work, and the air in the barrel is accelerated to circulate under the drive of the fan.

[0190] Step S803: The temperature sensor module obtains the temperature value D from 0 to T1. i .

[0191] The temperature sensor module is the temperature detection device 75. Here, i is the number of acquisitions, which is an integer greater than 0. The duration from 0 to time T1 is the second duration in the above embodiment. In the embodiment of the present application, the second duration can be any value between 30s and 5min, such as 1min.

[0192] Step S804: The control module processes the temperature data D i Get the ambient temperature D1.

[0193] The control module is the above-mentioned condenser blockage detection device 71. Here, D0 to Di The average value is determined as the ambient temperature D1 (i.e. the initial temperature mentioned above).

[0194] Step S805: the heater module starts heating.

[0195] The heater module is the above-mentioned heating device 72. After the ambient temperature D1 is determined, the heater module is controlled to start, that is, the air in the barrel is heated from the time T1.

[0196] Step S806: The temperature sensor module obtains temperature data D between time T1 and time T2. j , the preset temperature threshold D2 is reached at time T2.

[0197] Wherein, j is a positive integer, j = 1, 2, 3, ..., when the temperature sensor module obtains the temperature D j =D2, the drying process enters a stable stage (ie, the above-mentioned drying stable stage), and enters step S807.

[0198] Step S807, the control module processes T2 to obtain the load weight W1.

[0199] The control module searches the pre-stored relationship table according to the duration of time T1-T2, D1 and D2 to obtain the load weight W1. The load weight W1 here includes not only the clothes but also the water in the clothes to be dried.

[0200] Step S808: The control module processes D1 and W1 to retrieve the theoretical condensation efficiency E1.

[0201] The control module searches the pre-stored relationship table according to D1 and W1 to obtain the theoretical condensing efficiency of the condenser (ie, the above-mentioned reference condensing efficiency) E1.

[0202] Step S809: the water level sensor module obtains the condensed water amount W2.

[0203] The water level sensor module is the water level detection device 78. The water level sensor module detects the amount of water condensed by the condenser at time T3 to obtain W2.

[0204] Step S810: The control module processes and obtains the actual condensation efficiency E2.

[0205] The control module queries the pre-stored relationship table according to W2 and obtains the actual condensing efficiency of the condenser as E2.

[0206] Step S811, determining whether E1-E2 is greater than a preset efficiency threshold e.

[0207] The difference between E1 and E2 is the above-mentioned condensation efficiency difference △E. It is determined whether △E is greater than e. When △E>e, go to step S812; when △E≤e, go to step S813.

[0208] Step S812, after the program ends, the control module alarms to remind the user to clean the condenser module.

[0209] The condenser module is the above-mentioned condenser 76. After the drying process is finished, that is, after the clothes are dried, the control module outputs a prompt message to remind the user to clean the blockage in the condenser.

[0210] Here, the control module can remind the cleaning of the condenser in the form of flashing alarm lights or voice, etc. The reminder to clean the condenser can be after the current drying program is finished, or before the next drying program starts.

[0211] Step S813, the program ends normally.

[0212] When it is determined that there is less blockage in the condenser, there is no need to output a prompt message after the drying program is completed.

[0213] like Fig. 9 As shown, the detection method provided in the embodiment of the present application divides the drying process into a cold air stage 0-T1, a heating stage T1-T2, a temperature stabilization stage T2-T3 and subsequent stages.

[0214] The control module presets a duration, namely the second duration (equal to the duration of the moment 0-T1), and the heater module starts heating after the moment T1. The temperature sensor module obtains the 0-T1 temperature value Di, and the control module processes the temperature value Di to obtain the ambient temperature D1. The temperature sensor module obtains the T1-T2 temperature value Dj, and the temperature D2 begins to be in a relatively stable state at T2. The control module processes T2 to obtain the load weight W1. The control module processes the ambient temperature D1 and the load weight W1, and retrieves the preset reference condensation efficiency E1 from the control module. The control module sets a duration, namely the first duration (equal to the duration of the moment T2-T3), and the temperature D2 between T2 and T3 is in a relatively stable state.

[0215] The circulating air condenses part of the condensed water in the condenser module, the water level sensor module obtains the amount of condensed water W2 between T2 and T3, and the control module processes W2 to obtain the actual condensation efficiency E2.

[0216] The control module compares E1 and E2. When E1-E2>e, after the program ends, the control module alarms to remind the user to clean the condenser module. Otherwise, the program ends normally.

[0217] The technical problem to be solved by the embodiments of the present application is to improve the deficiency in the prior art that the blockage process of the condenser cannot be detected without adding a detection device, and to provide a condenser blockage detection method. By real-time detection of whether the condenser module is blocked and reminding the user to clean the condenser module in time, the drying time can be reduced, and the clothes can be prevented from being contaminated by lint, which is more energy-saving and hygienic.

[0218] The basic scheme of the embodiment of the present application is: the control module collects the temperature values ​​Di and Dj detected by the temperature sensor module of the dryer in different time periods of 0-T1 and T1-T2, calculates the ambient temperature D1 and the load weight W1, the water level sensor module obtains the condensed water volume W2, and the control module processes W2 to obtain the actual condensation efficiency E2. When E1-E2>e (preset efficiency threshold), after the program ends, the control module alarms to remind the user to clean the condenser module. Otherwise, the program ends normally. The condenser blockage detection method provided in the embodiment of the present application, through the opening and closing of the heater and the temperature sensor, determines the acquisition of the ambient temperature value and the load weight to retrieve the reference condensation efficiency E1, and obtains the actual condensation efficiency E2 through the water level sensor. When the condensation efficiency difference is greater than the preset efficiency threshold, an alarm is triggered after the program ends to remind the user to clean the condenser module.

[0219] The condenser blockage detection solution provided in the embodiment of the present application does not require the addition of additional detection devices to achieve real-time detection of whether the condenser is blocked. When blocked, the user is reminded to clean the condenser in time, which can reduce drying time, avoid lint contamination of clothes, and is more energy-saving and hygienic.

[0220] An embodiment of a second aspect of the present application provides a clothing processing device. Fig.10 A schematic diagram of a composition structure of a clothes processing device provided in an embodiment of the present application, according to Fig.10 The exemplary structure of the clothing processing device 1000 shown in the figure can foresee other exemplary structures of the clothing processing device 1000, so the structure described here should not be regarded as limiting.

The processor 1001 is configured to execute the program of the condenser blockage detection method stored in the memory to implement the steps in the condenser blockage detection method provided in the above embodiment.

[0222] The embodiment of the third aspect of the present application provides a computer-readable storage medium. In the embodiment of the present application, if the above-mentioned condenser blockage detection method is implemented in the form of a software function module and sold or used as an independent product, it can also be stored in a computer-readable storage medium. Based on such an understanding, the technical solution of the embodiment of the present application can be essentially or partly embodied in the form of a software product that contributes to the prior art. The computer software product is stored in a storage medium, including several instructions to enable a computer device (which can be a personal computer, a server, or a network device, etc.) to execute all or part of the methods described in each embodiment of the present application. The aforementioned storage medium includes: various media that can store program codes, such as a U disk, a mobile hard disk, a read-only memory (ROM, Read Only Memory), a magnetic disk or an optical disk. In this way, the embodiment of the present application is not limited to any specific combination of hardware and software.
