In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is 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.

In the following description, references to the terms "first \ second \ third" are only to distinguish similar objects and do not denote a particular order or importance, but rather "first \ second \ third" may, where permissible, be interchanged in a particular order or sequence so that embodiments of the present application described herein can be practiced in other than the order shown or described herein.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

A condenser clogging detection method, apparatus, laundry treating device, and computer-readable storage medium provided according to some embodiments of the present application are described below with reference to fig. 1 to 10.

Embodiments of a first aspect of the present application provide a method of condenser clogging detection. Fig. 1 is a schematic flow chart of an implementation of a method for detecting condenser clogging according to an embodiment of the present application, and as shown in fig. 1, the method includes steps S101 to S104 shown in fig. 1, and the steps are described below with reference to fig. 1.

Step S101, acquiring an initial temperature of gas in the clothes treatment equipment and a weight of a load in a barrel of the clothes treatment equipment.

The method for detecting blockage of the condenser is applied to the clothes treatment equipment, and the clothes treatment equipment can be equipment with a condensation function, such as a washing and drying integrated machine, a clothes dryer and the like. In the embodiment of the present application, the clothes treating apparatus is described by taking a clothes dryer as an example, and in the case that the following description is not specific, the clothes treating apparatus is referred to as a clothes dryer.

In the working process of the clothes dryer, air in the drying channel enters the barrel body from the air inlet of the barrel body and exchanges heat with damp clothes in the barrel body, so that not only can moisture in the damp clothes be taken away, but also thread scraps and the like in the barrel body can be taken away to cause blockage of a condenser. In order to avoid clogging of the condenser by the clogging substances such as thread scraps, a filter is generally arranged at the air outlet, the air with the clogging substances discharged from the air outlet of the barrel body passes through the filter, most of the clogging substances in the air are filtered, and a small part of the clogging substances pass through meshes or assembly gaps of the filter, or the clogging substances enter and are accumulated in the condenser due to the fact that the filter is not installed in place or is disassembled and assembled, so that the condensing efficiency of the condenser is reduced, and the drying time of the clothes dryer is prolonged.

On the premise of not increasing a detection device, the blockage degree of the condenser cannot be automatically detected in the related technology, and a user can only disassemble the clothes dryer regularly to clean the blockage accumulated in the condenser. The embodiment of the application provides a scheme for detecting the blockage degree of the condenser, firstly, after the clothes dryer is determined to enter the drying process, the initial temperature of gas in the clothes dryer and the weight of the load in the barrel of the clothes dryer are obtained, when the clothes dryer just enters the drying process, the heating device is not started, the initial temperature of the gas in the clothes dryer is equal to the environment temperature outside the barrel, and the influences of different environment temperatures on the condensing capacity of the condenser are different. The load here includes not only laundry but also moisture in the laundry.

Step S102, determining reference condensing efficiency of the condenser based on the initial temperature and the weight of the load.

In the case of the condenser without a blockage, the condensing efficiency of the condenser is fixed after the temperature and the load weight are determined, and the condensing efficiency is referred to as reference condensing efficiency. Because the main stage of drying clothes by the clothes dryer is that after the drying process enters the drying stable stage and before the air temperature of the clothes dryer reaches the preset temperature range, the air temperature is lower, the moisture in the clothes to be dried is taken away and limited, the water quantity condensed out by the condenser can be ignored, and even if a blockage exists at the moment, the influence on the condensation efficiency is very small. Based on this, in the embodiment of the present application, the condensing efficiency of the condenser will be determined based on the initial temperature and the weight of the load, and considered as the reference condensing efficiency of the condenser in the case where no clogging is present.

In the embodiment of the application, a corresponding relation table of each temperature value in a general environment temperature range, each load weight in a load range and the reference condensing efficiency of the condenser can be determined in advance according to experiments, and the corresponding relation table is stored in a storage of the clothes dryer. After the initial temperature and the weight of the load are obtained, a corresponding relation table is inquired according to the initial temperature and the weight of the load, and the reference condensing efficiency of the condenser is obtained.

Step S103, acquiring the humidity of the clothes to be processed in the barrel body in a 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.

In the embodiment of the application, according to the temperature of gas in a clothes dryer in the drying process, the drying process can be divided into a preheating stage, a drying stable stage and a cooling stage, wherein the preheating stage is a stage in which the temperature in a barrel body is lower than the lower limit value of a preset temperature range, the drying stable stage is a stage in which the temperature in the barrel body is maintained between the lower limit value and the upper limit value of the preset temperature range, and the cooling stage is a stage in which the temperature in the barrel body is reduced from the lower limit value of the preset temperature range to a safe temperature which can not damage a user. Wherein, the preheating stage can be divided into a cold air stage and a heating stage. The heating device is not started in the cold air stage, and after the cold air stage is finished, the heating device continuously operates at constant power in the temperature rising stage and the drying stabilizing stage. In the temperature rising stage, the precipitation rate of the condensed water is unstable due to the short starting time of the whole clothes drying system and the influence of the environmental temperature. And (4) entering a drying stabilization stage after the clothes drying system operates for a period of time, wherein the operation of the whole clothes drying system tends to be stable, the temperature is kept basically unchanged, and the precipitation rate of condensed water is kept stable until the clothes are dried. When the clothes are dried, the drying process is determined to enter a cooling stage, the heating device is turned off to stop heating, and the temperature of air in the clothes dryer is gradually reduced. Therefore, in the whole drying process, the clothes dryer can play the drying role most in the stable drying stage, and therefore the condensing efficiency of the condenser in the stable drying stage is taken as the actual working efficiency.

In the embodiment of the present application, the humidity of the laundry to be processed in the tub may be obtained, and one implementation manner may be that the laundry is in a stable drying stage during the drying process, and the humidity of the laundry to be processed is obtained at least twice, for example, the humidity of the laundry to be processed at the first time and the humidity of the laundry to be processed at the second time are obtained, and the first humidity value and the second humidity value are obtained respectively. When the actual condensing efficiency of the condenser is determined according to the humidity of the laundry to be treated, a humidity change value may be determined according to the first humidity value and the second humidity value, a first duration may be determined according to the first time and the second time, and the actual condensing efficiency of the condenser may be determined according to the humidity change value, the first duration, and the weight of the load.

In other embodiments, the amount of water dried, i.e. the reduced amount of water, i.e. the amount of water condensed by the condenser, may be obtained by taking the amount of water that the laundry to be treated is dried during the first time period. And determining the actual condensing efficiency of the condenser according to the amount of the dried water and the first time length. When the amount of water dried by the laundry for the first time period is obtained, the amount of water dried may be determined according to a humidity change value of the laundry for the first time period and a weight of the load, and finally, an actual condensing efficiency of the condenser may be determined according to the amount of water dried and the first time period.

And step S104, determining the blockage degree of the condenser according to the reference condensing efficiency and the actual condensing efficiency.

The actual condensing efficiency of the condenser is less than or equal to the reference condensing efficiency because the clogging in the condenser affects the condensing efficiency of the condenser. After the reference condensing efficiency and the actual condensing efficiency are determined, the blockage degree of the condenser can be determined according to the deviation between the actual condensing efficiency and the reference condensing efficiency. So need not to increase other detection device and can realize blockking up and detect, the user can confirm whether need clear up the jam of condenser according to the degree of blockking up, after confirming that the condenser blocks up, can in time clear up, ensures that the condenser is worked under the state of not blockking up to shorten when drying, and can avoid the jam to pollute the clothing, make clothing treatment facility more energy-conserving, more sanitary.

The embodiment of the application provides a method for detecting blockage of a condenser, which is applied to clothes treatment equipment and comprises the following steps: acquiring an initial temperature of gas in the clothes treatment equipment and a weight of a load in a barrel of the clothes treatment equipment; determining a reference condensing efficiency of the condenser based on the initial temperature and the weight of the load; acquiring the humidity of the clothes to be treated in the barrel body in a drying stable stage, and determining the actual condensing efficiency of the condenser based on the humidity of the clothes to be treated and the weight of the load; and determining the blockage degree of the condenser according to the reference condensing efficiency and the actual condensing efficiency. So, need not to increase other detection device and can realize blockking up and detect, the user can confirm whether need clear up the jam of condenser according to the jam degree, after confirming that the condenser blocks up, can in time clear up, ensures that the condenser is worked under the state of not blockking up to shorten when drying, and can avoid the jam to pollute the clothing, make clothing treatment facility more energy-conserving, more sanitary.

In some embodiments, the step S101 of acquiring the initial temperature of the laundry treatment apparatus and the weight of the load in the tub of the laundry treatment apparatus in the embodiment shown in fig. 1 may be implemented by steps S201 to S204 shown in fig. 2, and the steps are described below with reference to fig. 2:

in step S201, the temperature of the gas inside the laundry treating apparatus is detected to obtain an initial temperature.

In the embodiment of the present application, the temperature of the air in the dryer may be detected immediately after the drying process to obtain the initial temperature, which may deviate from the actual ambient temperature although the initial temperature may be obtained immediately. In order to obtain more accurate ambient temperature, in the embodiment of the application, after entering the drying process, the heating device is not started for the moment, the barrel body is controlled to rotate, the fan is started, so that the gas outside the barrel body and the gas inside the barrel body circulate, namely, the drying process is in a cold air stage, the temperature of the gas inside the barrel body is detected to obtain the initial temperature, the obtained initial temperature can be regarded as the ambient temperature outside the barrel body, and the initial temperature is closer to the real temperature of the clothes to be dried.

In practical applications, one way to obtain the initial temperature may be: determining to enter a drying process, and controlling a motor of the clothes treatment equipment to be started so as to drive the barrel body to rotate, wherein the heating device is not started; determining that a duration of rotation of the tub reaches a second duration, detecting a temperature of gas in the laundry treating apparatus to obtain a first temperature, and determining the first temperature as an initial temperature. In this kind of implementation, the staving rotates the back when the second is long, only needs to detect the temperature of gaseous in the clothes dryer once and can obtain initial temperature, and the advantage is that the number of times of detection is few, but probably once detects not accurate enough, can not ensure initial temperature's the degree of accuracy.

Another way to obtain the initial temperature may be: determining to enter a drying process, and controlling a motor of the clothes treatment equipment to be started so as to drive the barrel body to rotate, wherein the heating device is not started; detecting the temperature of the gas in the clothes treatment equipment for a plurality of times within a second time length to obtain a plurality of temperature values; an average value of the plurality of temperature values is determined as the initial temperature. In this implementation manner, after the barrel body rotates, the temperature of the gas in the barrel body is detected for multiple times within the second time period, multiple temperature values are obtained, and the initial temperature is determined according to the multiple temperature values, for example, an average value of the multiple temperature values is used as the initial temperature. This implementation, although requiring multiple detections, can ensure the accuracy of the initial temperature and thus the accuracy of the reference condensing efficiency.

In the embodiment of the present application, the second time period may be set to any value between 30s (seconds) and 5min (minutes), for example, the second time period is set to 3min. The means for detecting the temperature of the gas may be a temperature detecting means provided inside the tub, and the temperature detecting means may be a temperature sensor.

Step S202, controlling a heating device of the laundry treating apparatus to be activated to heat the gas.

After the initial temperature is obtained, the heating device of the clothes dryer is controlled to start, the gas in the barrel starts to be heated, and the temperature of the gas in the barrel starts to rise gradually.

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

The temperature of the gas in the barrel body tends to rise along with the starting of the heating device, and the temperature rising speed is related to the quantity of the clothes in the barrel body, if the quantity of the clothes in the barrel body is larger, the temperature rises slowly, and vice versa; thus, the weight of the load can be indirectly obtained according to the temperature rising rate; when the temperature of the gas is detected to reach the preset temperature value, the step S204 is executed; when the temperature of the gas is detected not to reach the preset temperature value, the step S203 is continuously executed.

In the embodiment of the application, in the stable stage of drying, the temperature is maintained in the staving and is predetermineeing the temperature range, this predetermineeing the temperature range can set up to arbitrary scope between 50 ℃ (degree centigrade) to 80 ℃, for example, predetermineeing the temperature range and setting up to 55 ℃ to 60 ℃, generally, the stoving temperature that the cloth of different materials can bear is different, predetermineeing the temperature range and can be according to the different materials of clothing, the corresponding a plurality of scopes that set up, the user is when selecting the stoving function, the material of the clothing of treating drying is selected, the corresponding temperature range of predetermineeing is set for.

The above-mentioned preset temperature value may be set to a value equal to the lower limit value of the preset temperature range (i.e., the preset temperature threshold value is 55 ℃). In some alternative embodiments, the preset temperature value may also be set to a value lower than the preset temperature threshold, for example to 50 ℃, so that the weight of the load may be obtained during a certain interval of temperature rise.

Step S204, acquiring the weight of the load in the barrel of the clothes treatment equipment.

Determining the weight of the load according to the initial temperature, the preset temperature value and the heating time, which can be realized as follows: detecting that the temperature of the gas reaches a preset temperature value, and acquiring the heating time of the heating device; and determining the weight of the load in the barrel according to the heating time length, the initial temperature and the preset temperature value.

In the embodiment of the application, the corresponding relation table of each temperature value in the general environment temperature range, each load weight in the load range, the preset temperature value and the heating time can be determined in advance according to experiments, for example, the experiment measurement: the barrel body bears a load of 5kg (kilogram), and the gas in the barrel body is heated to 60 ℃ from the ambient temperature of 25 ℃ for 20min; the drum carries a load of 6kg (kilograms), the air in the drum is heated from ambient temperature 25 ℃ to 60 ℃, it takes 25min, etc., and these experimental measurements are stored in the memory of the dryer in the form of a correspondence table. After the initial temperature, the preset temperature value and the heating time are obtained, the corresponding relation table is inquired according to the initial temperature, the preset temperature value and the heating time, and the weight of the load in the barrel body is obtained.

In some embodiments, the step S103 "obtaining the humidity of the laundry to be processed in the drying stable stage in the tub 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" in the embodiment shown in fig. 1 can be implemented by steps S301 to S304 shown in fig. 3, and the following steps are described with reference to fig. 3:

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 body at a first moment to obtain a first humidity value.

Here, the humidity value of the laundry to be processed in the tub is detected at the first time, and a time when the temperature of the gas just reaches a lower limit value (i.e., a preset temperature threshold) of the preset temperature range, that is, a time when the drying process just enters the drying stable stage may be used as the first time, and any other time in the drying stable stage may also be used as the first time. In the embodiment of the present application, the clothes dryer may detect a humidity value of the laundry to be dried by using a humidity detecting device (e.g., a humidity sensor).

Step S302, detecting the humidity of the laundry to be treated in the tub at a second time to obtain a second humidity value.

Here, the humidity value of the laundry to be treated in the tub is detected at the second time, which may be any time of the drying stabilizing period after the first time. In some embodiments, the second time may determine the second time at which the humidity value is acquired again according to the first time and a preset time interval. The preset time interval may be the first time length, such as any value between 15min and 35min, for example, 25min.

Because the moisture in the clothes to be dried is evaporated and condensed in the drying process, the humidity of the clothes to be dried is smaller and smaller, and the obtained second humidity value is smaller than the first humidity value.

Step S303, determining a humidity change value of the clothes to be processed in a first time period according to the first humidity value and the second humidity value.

The first time period is a time period from the first time to the second time, i.e. a time interval between the first time and the second time. And determining the difference value of the first humidity value H1 acquired at the first moment and the second humidity value H2 acquired at the second moment as the humidity change value of the clothes to be treated in the time period.

And step S304, determining the actual condensing efficiency of the condenser according to the humidity change value, the first time length and the weight of the load.

In the embodiment of the application, a corresponding relation table between the preset temperature range, the load weight, the duration and the humidity change value in the load range and the actual condensing efficiency of the condenser can be determined in advance according to experiments, and the corresponding relation table is stored in a storage of the clothes dryer. And inquiring the corresponding relation table according to the weight of the load, the first duration and the humidity change value obtained in the step S204 to obtain the actual condensing efficiency of the condenser.

In other embodiments, determining the actual condensing efficiency of the condenser based on the humidity of the laundry to be treated and the weight of the load may be implemented as: determining a reduced amount of water in the first time period of the drying stable stage for the laundry to be treated according to the plurality of humidity values, and determining an actual condensing efficiency of the condenser according to the first time period and the reduced amount of water. The water amount reduced by the clothes to be treated in the first time period can be obtained by detecting the change of the humidity value of the clothes in the first time period, and can also be obtained by detecting the water amount condensed by the condenser through the water level sensor. In the embodiment of the application, a corresponding relation table among the preset temperature range, the load weight and time length in the load range, the amount of water reduced by the clothes and the actual condensing efficiency of the condenser can be determined in advance according to experiments, and the corresponding relation table is stored in a storage of the clothes dryer. And inquiring the corresponding relation table according to the weight of the load, the first time length and the water quantity reduced by the clothes to be processed in the first time length obtained in the step S204 to obtain the actual condensing efficiency of the condenser.

In the embodiment of the application, the actual condensation efficiency of the condenser is determined according to the humidity change value obtained by detecting the humidity of the clothes to be processed for multiple times in the first time length in the drying process, and preparation is made for determining the blockage degree of the condenser according to the actual condensation efficiency and the reference condensation efficiency.

In some embodiments, the step S104 "determining the clogging degree of the condenser according to the reference condensing efficiency and the actual condensing efficiency" in the embodiment shown in fig. 1 can be implemented by steps S401 to S404 shown in fig. 4, and the steps are explained below with reference to fig. 4:

in step S401, a condensing efficiency difference is determined according to the reference condensing efficiency and the actual condensing efficiency.

Here, the reference condensing efficiency is denoted as E1, the actual condensing efficiency is denoted as E2, and the condensing efficiency difference is denoted as Δ E, and the condensing efficiency difference is calculated according to Δ E = E1-E2.

Step S402, judging whether the condensing efficiency difference value is larger than a preset efficiency threshold value.

When the difference value of the condensing efficiencies is larger than the preset efficiency threshold value, the difference between the actual condensing efficiency and the reference condensing efficiency is larger, the number of the blocking objects is considered to be more, the influence on the condensing efficiency of the condenser is larger, and then the step S403 is executed; when the difference in condensing efficiency is less than or equal to the preset efficiency threshold, it indicates that the difference between the actual condensing efficiency and the reference condensing efficiency is small, and it is determined that the blockage is small and the influence on the condensing efficiency of the condenser is not large, and then the process proceeds to step S404.

In step S403, the clogging degree of the condenser is determined as a serious clogging.

In step S404, the clogging degree of the condenser is determined to be slight clogging.

In the embodiment of the application, the difference value between the reference condensing efficiency and the actual condensing efficiency is compared with a preset efficiency threshold value, and when the difference value between the reference condensing efficiency and the actual condensing efficiency is greater than the preset efficiency threshold value, the blockage degree of the condenser is determined to be serious blockage, and the blockage degree needs to be cleaned; when the difference value between the reference condensing efficiency and the actual condensing efficiency is smaller than or equal to the preset efficiency threshold value, the blockage degree of the condenser is determined to be slightly blocked, and the condenser does not need to be cleaned.

The prior art scheme has two drawbacks, one is that the filter screen filters the line bits in the circulating air incompletely, and after long-time use, the line bits can block up the condenser surface. Secondly, the condenser is not detected after being blocked, and a user is not reminded of the blockage, so that the user cannot clean the condenser in time. After the condenser is blocked by the thread scraps, the condensing efficiency is reduced, more water vapor of the circulating air enters the clothes to be dried again, the drying time is longer, and the accumulation of the thread scraps breeds bacteria to pollute the clothes.

In step S801, a drying process is started.

Step S802, the motor drive module is started.

The motor driving module is the motor 77. When the clothes drying program is started, the motor driving module starts to work, and air in the barrel body is driven by the fan to circulate in an accelerated mode.

In step S803, the temperature sensor module obtains a temperature value D from 0 to T1 _i 。

This temperature sensor module is the temperature detection device 75. Where i is the number of acquisitions, an integer greater than 0. The time period from time 0 to time T1 is the second time period in the above embodiment. In this embodiment of the application, the second duration may take any value between 30s and 5min, for example, the second duration takes 1min.

The control module is the condenser blockage detection device 71. Here, D may be ₀ To D _i Is determined as a ringAmbient temperature D1 (i.e., the initial temperature described above).

In step S805, the heater module starts heating.

The heater module is the heating device 72. After the ambient temperature D1 is determined, the heater module is controlled to be started, namely, the air in the barrel body is heated from the moment T1.

Step S806, the temperature sensor module obtains temperature data D between the time T1 and the time T2 _j And the moment T2 reaches a preset temperature threshold value D2.

Wherein j is a positive integer, j =1,2,3, \8230;, when the temperature sensor module obtains the temperature D _j If "= D2", the drying process enters the stable stage (i.e., the above-mentioned drying stable stage), and then the process proceeds to step S807.

In step S807, the control module processes T2 to obtain the load weight W1.

And the control module inquires a pre-stored relation table according to the time length of the T1-T2 and the D1 and the D2 to obtain the load weight W1. The load weight W1 here includes not only laundry but also moisture to be dried in the laundry.

In step S808, the control module processes D1 and W1 and retrieves the theoretical condensation efficiency E1.

The control module inquires a pre-stored relation table according to the D1 and the W1 to obtain the theoretical condensation efficiency (namely the reference condensation efficiency) E1 of the condenser.

In step S809, the humidity sensor module acquires the laundry humidity value Mk from time T2 to time T3.

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

In step S810, the control module processes Mk to obtain the actual condensing efficiency E2.

And the control module inquires a prestored relation table according to the Mk to obtain the actual condensing efficiency E2 of the condenser.

Step S811, judge whether E1-E2 is greater than the preset efficiency threshold E.

The difference value between E1 and E2 is the above-mentioned difference value of condensing efficiency Δ E, judge whether Δ E is greater than E, when Δ E > E, enter step S812; when Δ E is equal to or less than E, the process proceeds to step S813.

Here, the control module reminds the cleaning of the condenser that the alarm mode can be the modes of alarm lamp flashing or voice and the like. The warning mode of reminding to clean the condenser can be used after the drying program is finished, and can also be used before the next drying program is started.

In step S813, the routine ends normally.

When the condenser is determined to have less blockage, prompt information does not need to be output after the drying program is finished.

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

The control module presets a time length, namely a second time length (equal to the time length from 0 to T1), and the heater module starts heating after the time T1. The temperature sensor module obtains a temperature value Di of 0-T1, and the control module processes the temperature value Di to obtain the environment temperature D1. The temperature sensor module obtains a temperature value Dj from T1 to T2, and the temperature D2 starts 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 a preset reference condensing efficiency E1 from the control module. The control module sets a duration, i.e., a first duration (equal to the duration of time T2-T3), that the temperature D2 between T2 and T3 is in a relatively steady state.

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

The control module compares E1 and E2, and when E1-E2 is larger than E, the control module gives an alarm to remind a user to clean the condenser module after the program is finished. Otherwise, the procedure ends normally.

The technical problem that this application embodiment will solve lies in improving among the prior art can't carry out the not enough that detects to the jam procedure of condenser under the prerequisite that does not increase detection device, provides a condenser jam detection method, through the real-time detection and remind the user in time to clear up the condenser module to whether the condenser module blocks up, can reduce the stoving time, avoids the thread scraps to pollute the clothes, and is more energy-conserving, more sanitary.

The basic scheme of the embodiment of the application is as follows: the control module collects temperature values Di and Dj detected by the clothes dryer temperature sensor modules 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 a clothes humidity value Mk in a period of time in a temperature stable state, and the control module processes the Mk to obtain actual condensation efficiency E2. And when E1-E2 is larger than E (preset efficiency threshold), the control module gives an alarm to remind a user to clean the condenser module after the program is finished. Otherwise, the procedure ends normally. According to the condenser blockage detection method provided by the embodiment of the application, the ambient temperature value and the load weight are judged and acquired through the opening and closing of the heater and the temperature sensor, the reference condensing efficiency E1 is obtained, and the actual condensing efficiency E2 is obtained through the humidity value. And when the condensing efficiency difference value is larger than a preset efficiency threshold value, alarming to remind a user of cleaning the condenser module after the program is finished.

The detection scheme that this application embodiment provided condenser blocks up need not increase extra detection device and realizes the real-time detection whether the condenser blocks up, reminds the user in time to clear up the condenser when blockking up, can reduce the stoving time, avoid the line bits to pollute the clothes, more energy-conserving, more sanitary.
