Description

Technical Field

[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 blockage in 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 blockage in 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] Step S102: determining a reference condensing efficiency of the condenser based on the initial temperature and the weight of the load.

[0071] 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.

[0072] 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.

[0073] Step S103, obtaining the humidity of the clothes to be processed in the barrel during the stable drying stage, and determining the actual condensing efficiency of the condenser based on the humidity of the clothes to be processed and the weight of the load.

[0074] 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.

[0075] In an embodiment of the present application, the humidity of the clothes to be processed in the barrel is obtained. One implementation method may be to obtain the humidity of the clothes to be processed at least twice when the drying process is in a stable drying stage. For example, the humidity of the clothes to be processed at the first moment and the second moment is obtained to obtain the first humidity value and the second humidity value respectively. When determining the actual condensation efficiency of the condenser according to the humidity of the clothes to be processed, the humidity change value may be determined according to the first humidity value and the second humidity value, the first time duration may be determined according to the first moment and the second moment, and the actual condensation efficiency of the condenser may be determined according to the humidity change value, the first time duration and the weight of the load.

[0076] In other embodiments, the amount of water dried by the laundry to be processed within the first time period can be obtained, and the amount of water dried is the amount of water reduced, that is, the amount of water condensed by the condenser. The actual condensation efficiency of the condenser is determined according to the amount of water dried and the first time period. When obtaining the amount of water dried by the laundry to be processed within the first time period, the amount of water dried can be determined according to the humidity change value of the laundry to be processed within the first time period and the weight of the load, and finally the actual condensation efficiency of the condenser is determined according to the amount of water dried and the first time period.

[0077] Step S104, determining the blockage degree of the condenser according to the reference condensation efficiency and the actual condensation efficiency.

[0078] 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.

[0079] 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 humidity of the clothes to be processed in the barrel during the stable drying stage, and determining the actual condensation efficiency of the condenser based on the humidity of the clothes to be processed and the weight of the load; 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 the blockage of the condenser needs to be cleaned 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 preventing the blockage from contaminating the clothes, making the clothing processing device more energy-efficient and more hygienic.

[0080] 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:

[0081] Step S201, detecting the temperature of the gas in the clothes processing device to obtain an initial temperature.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Step S202, controlling a heating device of the clothes processing equipment to start heating the gas.

[0087] 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.

[0088] Step S203, detecting whether the temperature of the gas reaches a preset temperature value.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] Step S204, obtaining the weight of the load in the barrel of the clothing processing device.

[0093] 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.

[0094] 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.

[0095] In some embodiments, the above Figure 1 In the embodiment shown, step S103 of "obtaining the humidity of the laundry to be processed in the barrel during the stable drying stage, and determining the actual condensing efficiency of the condenser based on the humidity of the laundry to be processed and the weight of the load" can be performed as follows: Figure 3 Steps S301 to S304 are implemented as shown below. Figure 3 Explain each step:

[0096] Step S301, determining that the temperature of the gas reaches a preset temperature range, and detecting the humidity of the clothes to be processed in the barrel at a first moment to obtain a first humidity value.

[0097] Here, the humidity value of the clothes to be processed in the barrel is detected at the first moment, and the moment when the temperature of the gas just reaches the lower limit of the preset temperature range (i.e., the preset temperature threshold), that is, the moment when the drying process just enters the drying stable stage, can be used as the first moment, or any other moment in the drying stable stage can be used as the first moment. In the embodiment of the present application, the clothes dryer can use a humidity detection device (such as a humidity sensor) to detect the humidity value of the clothes to be dried.

[0098] Step S302, detecting the humidity of the clothes to be processed in the barrel at a second moment to obtain a second humidity value.

[0099] Here, the humidity value of the clothes to be processed in the barrel is detected at the second moment, which can be any moment in the drying stable stage after the first moment. In some embodiments, the second moment can be determined according to the first moment and the preset time interval to obtain the second moment of the humidity value again. The preset time interval can be the first time length mentioned above, such as being set to any value between 15 minutes and 35 minutes, for example, being set to 25 minutes.

[0100] Since the moisture in the clothes to be dried is evaporated and condensed during the drying process, the humidity of the clothes to be dried becomes lower and lower, so the acquired second humidity value is lower than the first humidity value.

[0101] Step S303: determining a humidity change value of the laundry to be processed within a first time period according to the first humidity value and the second humidity value.

[0102] The first duration here is the duration from the first moment to the second moment, that is, the time interval between the first moment and the second moment. The difference between the first humidity value H1 obtained at the first moment and the second humidity value H2 obtained at the second moment is determined as the humidity change value of the laundry to be processed in the time period.

[0103] Step S304: determining the actual condensing efficiency of the condenser according to the humidity change value, the first time period and the weight of the load.

[0104] 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 humidity change value 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. According to the above step S204, the weight of the load, the first duration, and the humidity change value are obtained, and the correspondence table is queried to obtain the actual condensing efficiency of the condenser.

[0105] In other embodiments, determining the actual condensation efficiency of the condenser based on the humidity of the clothes to be processed and the weight of the load can be implemented as follows: according to multiple humidity values, determining the amount of water reduced by the clothes to be processed in the first time period of the drying stabilization phase, and determining the actual condensation efficiency of the condenser according to the first time period and the reduced water amount. The amount of water reduced by the clothes to be processed in the first time period can be obtained by detecting the change in the humidity value of the clothes in the first time period, or by detecting the amount of water condensed by the condenser through a water level sensor. In the embodiment of the present application, a corresponding relationship table between the weight of each load in the preset temperature range, the load range, the time period, the amount of water reduced by the clothes and the actual condensation efficiency of the condenser can be determined in advance according to experiments, and the corresponding relationship table is stored in the memory of the dryer. According to the above step S204, the weight of the load, the first time period, and the amount of water reduced by the clothes to be processed in the first time period are obtained, and the corresponding relationship table is queried to obtain the actual condensation efficiency of the condenser.

[0106] In an embodiment of the present application, the actual condensation efficiency of the condenser is determined based on the humidity change value obtained by repeatedly detecting the humidity of the clothes to be processed within a first period of time during the drying process, preparing for the subsequent determination of the blockage degree of the condenser based on the actual condensation efficiency and the reference condensation efficiency.

[0107] 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:

[0108] Step S401, determining a condensation efficiency difference according to a reference condensation efficiency and an actual condensation efficiency.

[0109] 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.

[0110] Step S402, determining whether the condensation efficiency difference is greater than a preset efficiency threshold.

[0111] 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.

[0112] Step S403: determining the blockage degree of the condenser as severe blockage.

[0113] Step S404: determining the blockage degree of the condenser as slight blockage.

[0114] 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.

[0115] 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.

[0116] 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:

[0117] 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.

[0118] 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.

[0119] Step S502: determining a reference condensing efficiency of the condenser based on the initial temperature and the weight of the load.

[0120] Step S503, obtaining the humidity of the clothes to be processed in the barrel during the stable drying stage, and determining the actual condensing efficiency of the condenser based on the humidity of the clothes to be processed and the weight of the load.

[0121] Step S504: determining the blockage degree of the condenser according to the reference condensation efficiency and the actual condensation efficiency.

[0122] Step S505, detecting the humidity inside the barrel to obtain a first humidity value.

[0123] 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.

[0124] Step S506, determining whether the first humidity value is less than a drying humidity threshold.

[0125] 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.

[0126] Step S507, determining to end the drying process.

[0127] Step S508, determining whether the blockage degree of the condenser is severe.

[0128] 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.

[0129] Step S509, controlling the alarm device of the clothes processing equipment to output prompt information.

[0130] 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.

[0131] Step S510, end.

[0132] 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.

[0133] 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 also outputs 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.

[0134] 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, outputs a prompt message after the drying program ends, so that the user is promptly informed that the condenser is blocked, and 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.

[0135] 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:

[0136] 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.

[0137] 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.

[0138] 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.

[0139] During the second time period, the drying process is in the cold wind stage.

[0140] Step S603: determining an average value of the plurality of temperature values ​​as the initial temperature of the gas in the clothes treating device.

[0141] 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.

[0142] In some other embodiments, the above steps S602 and S603 may be replaced by steps S602' and S603':

[0143] Step S602', determining whether the duration of the barrel body rotation reaches a second duration.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] Step S604, controlling the heating device of the clothes processing equipment to start to heat the gas.

[0148] 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.

[0149] Step S605, determining whether the temperature of the gas reaches a preset temperature value.

[0150] 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 .

[0151] Step S606, obtaining the heating time of the heating device.

[0152] Step S607, determining the weight of the load in the barrel according to the heating time, the initial temperature and the preset temperature value.

[0153] 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.

[0154] Step S608: determining a reference condensing efficiency of the condenser based on the initial temperature and the weight of the load.

[0155] 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.

[0156] Step S609, detecting the humidity of the clothes to be processed in the barrel multiple times within the first time period of the drying stabilization phase to obtain multiple humidity values.

[0157] Here, multiple detections are performed within the first time period, and the detection may start from when the temperature of the gas reaches a preset temperature range, or may start from the start of any other time period in the drying stabilization phase whose duration is equal to the first time period. Exemplarily, the humidity of the clothes to be processed is detected at a first moment to obtain a first humidity value, and the humidity of the clothes to be processed is detected at a second moment to obtain a second humidity value, wherein the duration between the first moment and the second moment is the first duration. In the embodiment of the present application, the clothes dryer may use a humidity sensor to detect the humidity value of the clothes to be dried.

[0158] Step S610, determining the amount of water reduced by the laundry to be processed within a first time period according to the plurality of humidity values ​​and the weight of the load.

[0159] The amount of water reduced in the clothes to be treated within the first time period can be obtained by detecting the change in the humidity value of the clothes within the first time period, such as determining a humidity change value according to the first humidity value and the second humidity value, and determining the amount of water reduced in the clothes to be treated within the first time period according to the humidity change value and the weight of the load. In another implementation, the amount of water reduced in the clothes to be treated within the first time period can also be obtained by detecting the amount of water condensed by the condenser through a water level sensor.

[0160] Step S611, determining the actual condensing efficiency of the condenser according to the first time period and the amount of water reduced by the laundry to be processed within the first time period.

[0161] In the above correspondence table, the correspondence between the preset temperature range, the weight of each load in the load range, the duration, the amount of water reduced by the clothes and the actual condensation efficiency of the condenser determined in advance according to experiments can also be stored. After obtaining the first duration and the amount of water reduced by the clothes to be processed within the first duration, the correspondence table is queried to obtain the actual condensation efficiency of the condenser.

[0162] In some other embodiments, the above step S610 and step S611 may be replaced by:

[0163] Step S610': determining the humidity change value of the laundry to be processed within a first time period according to the multiple humidity values.

[0164] The difference between the first humidity value H1 obtained at the first moment and the second humidity value H2 obtained at the second moment is determined as the humidity change value of the clothes to be processed in the time period. The first time period here is the time period from the first moment to the second moment, that is, the time interval between the first moment and the second moment.

[0165] Step S611', determining the actual condensing efficiency of the condenser according to the humidity change value, the first time period and the weight of the load.

[0166] At this time, in the above correspondence table, a correspondence table between the preset temperature range, the load weight, the first time length, the humidity change value 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 time length and the humidity change value are obtained, the correspondence table is queried to obtain the actual condensing efficiency of the condenser.

[0167] Step S612: determining a condensation efficiency difference according to the reference condensation efficiency and the actual condensation efficiency.

[0168] 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.

[0169] Step S613, determining whether the condensation efficiency difference is greater than a preset efficiency threshold.

[0170] 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 S614; 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 S615.

[0171] Step S614: determining the blockage degree of the condenser as severe blockage.

[0172] After determining the blockage degree of the condenser, proceed to step S616 to continue the drying process.

[0173] Step S615, determining the blockage degree of the condenser as slight blockage.

[0174] Step S616, detecting the humidity inside the barrel to obtain a first humidity value.

[0175] 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.

[0176] Step S617, determining whether the first humidity value is less than a drying humidity threshold.

[0177] 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 S618 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 S616 is returned to re-acquire the first humidity value.

[0178] Step S618, determining to end the drying process.

[0179] Step S619, determining whether the blockage degree of the condenser is severe.

[0180] When it is determined according to step S614 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 S620; when it is determined according to step S615 that the blockage degree of the condenser is slight, no cleaning is required and enter step S621.

[0181] Step S620, controlling the alarm device of the clothes processing equipment to output prompt information.

[0182] 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.

[0183] Step S621, end.

[0184] 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 stable drying stage, the actual condensation efficiency of the condenser is determined according to the detected humidity of the clothing to be processed in the barrel, 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 in 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 clothing by blockage, making the clothing processing equipment more energy-efficient and more hygienic.

[0185] 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.

[0186] 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.

[0187] 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.

[0188] 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 and a motor 77.

[0189] Among them, the heating device 72 is arranged in the drying tunnel for heating the gas in the dryer 70; the barrel body 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 body 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 body 73 for condensing the gas in the dryer; the motor 77 is arranged at the lower end of the barrel body 73 for driving the barrel body 73 to rotate; the water level detection device 78 and the condenser blockage detection device 71 are used to control the heating device 72, the barrel body 73, the humidity detection device 74, the temperature detection device 75, the condenser 76 and the motor 77 to detect the degree of condenser blockage.

[0190] 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.

[0191] In the present application embodiment, Figure 7 As shown, the clothes dryer 70 may further include a water level detection device 78 and a filter 79. The water level detection device 78 is disposed at the water outlet of the condenser 76 (not shown in the figure) to detect the amount of water condensed by the condenser 76; the filter 79 is disposed between the air outlet 731 of the barrel 73 and the condenser 76 to filter the gas discharged from the air outlet 731 with lint and the like that may clog the condenser, thereby reducing the amount of clogged matter that enters the condenser.

[0192] 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 above-mentioned barrel body 73). After the heat exchange between the circulating air and the clothes, some lint will be carried with it. The lint filter module (i.e., the above-mentioned 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 accumulate on it. The humidity sensor module detects the humidity of the clothes in real time, and 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.

[0193] 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.

[0194] Step S801, the clothes drying process starts.

[0195] Step S802: the motor drive module is started.

[0196] 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.

[0197] Step S803: The temperature sensor module obtains the temperature value D from 0 to T1. i .

[0198] 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.

[0199] Step S804: The control module processes the temperature data D i Get the ambient temperature D1.

[0200] The control module is the above-mentioned condenser blockage detection device 71. Here, D0 to D i The average value is determined as the ambient temperature D1 (i.e. the initial temperature mentioned above).

[0201] Step S805: the heater module starts heating.

[0202] 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.

[0203] 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.

[0204] 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.

[0205] Step S807, the control module processes T2 to obtain the load weight W1.

[0206] 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.

[0207] Step S808: The control module processes D1 and W1 to retrieve the theoretical condensation efficiency E1.

[0208] 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.

[0209] Step S809: the humidity sensor module obtains the clothing humidity value Mk from time T2 to time T3.

[0210] The humidity sensor module is the humidity detection device 74. The humidity sensor module detects the humidity value of the clothes from time T2 to T3 to obtain Mk.

[0211] Step S810: The control module processes Mk to obtain the actual condensation efficiency E2.

[0212] The control module queries the pre-stored relationship table according to Mk and obtains the actual condensing efficiency of the condenser as E2.

[0213] Step S811, determining whether E1-E2 is greater than a preset efficiency threshold e.

[0214] 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.

[0215] Step S812, after the program ends, the control module alarms to remind the user to clean the condenser module.

[0216] 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.

[0217] 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.

[0218] Step S813, the program ends normally.

[0219] 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.

[0220] 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.

[0221] 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.

[0222] During the temperature stabilization stage from T2 to T3, the humidity sensor module detects the humidity Mk of the clothes in real time, and the control module processes Mk to obtain the actual condensation efficiency E2.

[0223] 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.

[0224] 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.

[0225] 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, and obtains the theoretical condensation efficiency E1. The humidity sensor module obtains the humidity value Mk of the clothes for a period of time when the temperature is stable, and the control module processes Mk 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 judges and obtains the ambient temperature value and the load weight to retrieve the reference condensation efficiency E1 through the opening and closing of the heater and the temperature sensor, and obtains the actual condensation efficiency E2 through the humidity value. 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.

[0226] 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.

[0227] 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. For example, some components described below can be omitted, or components not described below can be added to meet the special needs of certain applications.
