Abstract

Disclosed are a detection method for a laundry treatment apparatus and a laundry treatment apparatus. An ambient temperature is obtained when a drying program is started, and a temperature reference of an air-out side of a lint filter is determined according to the ambient temperature. Then, after waiting for the drying program to run for a first set time, a first detected temperature on the air-out side of the lint filter is obtained, and the first detected temperature is compared to the determined temperature reference. If the first detected temperature is lower than the temperature reference, then the drying program continues to run; otherwise, a heater is turned off and a fan is kept running. The temperature is lowered by means of the running of the fan, and a second detected temperature on the air-out side of the lint filter is detected again. The difference between the first detected temperature and the second detected temperature is calculated. If the difference is greater than a set threshold, then a prompt that the lint filter is clogged is issued. In the present invention, the ambient temperature is introduced as the temperature reference during an initial stage of the drying program to improve the accuracy of temperature rise determination, thereby improving the determination accuracy of clogging conditions of the lint filter.

本发明旨在提出一种衣物处理装置的检测方法，针对烘干程序中线屑过滤器的堵塞情况，在不提高检测成本的情况下，提高对线屑过滤器堵塞程度的判断准确性。The purpose of the present invention is to provide a detection method for a clothes processing device, aiming at the clogging of the lint filter in the drying program, and improving the judgment accuracy of the clogging degree of the lint filter without increasing the detection cost.
具体的，如图1所示，本发明提出的衣物处理装置的检测方法，包括如下步骤：Specifically, as shown in Figure 1, the detection method of the clothes processing device proposed by the present invention includes the following steps:
步骤S1：启动烘干程序，获取环境温度。Step S1: Start the drying program to obtain the ambient temperature.
在干衣机、洗涤烘干一体机的衣物处理装置启动烘干程序后，首先获取其周围的环境温度。After the laundry processing device of the clothes dryer or the all-in-one washing and drying machine starts the drying program, the ambient temperature around it is first acquired.
环境温度的获取可以通过温度传感器、通过互联网等方式获取，本发明不予具体限定。The ambient temperature may be obtained through a temperature sensor, the Internet, etc., which is not specifically limited in the present invention.
步骤S2：根据环境温度确定线屑过滤器出风侧的温度基准。Step S2: Determine the temperature reference of the air outlet side of the lint filter according to the ambient temperature.
烘干程序中，加热温度T相同的情况下，理论上，在线屑过滤器不堵塞情况下，风道排出口或线屑过滤器的出风侧的热空气的温度也应该为T，但实际上，环境温度会影响风道排出口或线屑过滤器的出风侧的热空气的温度，导致风道排出口或线屑过滤器的出风侧的热空气温度略有不同，环境温度越高，风道排出口或线屑过滤器的出风侧的热空气温度越高。In the drying program, when the heating temperature T is the same, theoretically, if the lint filter is not blocked, the temperature of the hot air at the outlet of the air duct or the air outlet side of the lint filter should also be T, but in practice In general, the ambient temperature will affect the temperature of the hot air at the outlet of the air duct or the outlet side of the lint filter, resulting in slightly different temperatures of the hot air at the outlet of the air duct or the outlet side of the lint filter. The higher the temperature, the higher the temperature of the hot air at the outlet of the duct or on the outlet side of the lint filter.
以衣物处理装置在烘干程序中设定的加热温度均为70℃为例，线屑过滤器不堵塞情况下，不同环境温度，风道排出口或线屑过滤器的出风侧的热空气的温度如下表一所示：Taking the heating temperature set in the drying program of the clothes treatment device as an example, when the lint filter is not clogged, the temperature of the hot air at the outlet of the air duct or the air outlet side of the lint filter will vary depending on the ambient temperature. The temperature is shown in Table 1 below:
表一Table I
环境温度t（℃）Ambient temperature t (°C) t<15t<15 15≤t<2515≤t<25 25≤t<3525≤t<35 35≤t<4535≤t<45 t≥45t≥45
线屑过滤器出风侧温度（℃）Air outlet temperature of lint filter (°C) 7070 7272 7474 7676 7878
基于上述分析，本发明根据环境温度，为线屑过滤器的出风侧在其不堵塞情况下划分温度基准，不同环境温度下，采用不同的温度基准对线屑过滤器的堵塞情况进行判断，从而能够提高判断的精准度。Based on the above analysis, the present invention divides the temperature reference for the air outlet side of the lint filter according to the ambient temperature when it is not clogged. Under different ambient temperatures, different temperature references are used to judge the clogging of the lint filter. Thereby, the accuracy of judgment can be improved.
步骤S3：烘干程序运行第一设定时间后，获取线屑过滤器出风侧的第一检测温度。Step S3: After the drying program runs for the first set time, obtain the first detected temperature of the air outlet side of the lint filter.
烘干程序持续运行第一设定时间t1后，衣物处理装置获取线屑过滤器出风侧的温度：第一检测温度T1。After the drying program continues to run for the first set time t1, the clothes processing device obtains the temperature of the air outlet side of the lint filter: the first detected temperature T1.
步骤S4：比较第一检测温度与确定的温度基准，在第一检测温度高于温度基准时，关闭加热器并维持风机运转。Step S4: Comparing the first detected temperature with the determined temperature reference, when the first detected temperature is higher than the temperature reference, turn off the heater and keep the fan running.
比较第一检测温度T1和步骤S2中确定的温度基准T0，若T1≤T0，则说明线屑过滤器没有达到堵塞出风口的状况，可以继续执行烘干程序运行。Comparing the first detected temperature T1 with the temperature reference T0 determined in step S2, if T1≤T0, it means that the lint filter has not reached the condition of blocking the air outlet, and the drying program can continue to be executed.
若T1>T0，则线屑过滤器存在堵塞的可能性，需要进一步进行判断，进一步判断的手段是：关闭加热器停止加热，维持风机运转，通过风机运转实施降温。If T1>T0, the lint filter may be clogged, and further judgment is required. The method for further judgment is: turn off the heater to stop heating, keep the fan running, and implement cooling through the fan operation.
步骤S5：获取线屑过滤器出风侧的第二检测温度，计算第一检测温度与第二检测温度的差值。Step S5: Obtain the second detected temperature on the air outlet side of the lint filter, and calculate the difference between the first detected temperature and the second detected temperature.
关闭加热器维持风机运转期间，风道温度逐渐下降，衣物处理装置获取线屑过滤器出风侧的第二检测温度T2，并计算第一检测温度T1与第二检测温度T2的差值ΔT=T1-T2。During the period when the heater is turned off and the fan is running, the temperature of the air duct gradually drops, and the clothes processing device obtains the second detected temperature T2 on the air outlet side of the lint filter, and calculates the difference between the first detected temperature T1 and the second detected temperature T2 ΔT= T1-T2.
设定一个阈值T3，若差值ΔT=T1-T2≤T3，说明在关闭加热器后，T2下降明显，说明风道循环基本正常，线屑过滤器堵塞的可能性不大。Set a threshold T3, if the difference ΔT=T1-T2≤T3, it means that after the heater is turned off, T2 drops significantly, indicating that the air duct circulation is basically normal, and the lint filter is unlikely to be clogged.
步骤6、在差值大于设定阈值时，发出线屑过滤器堵塞提示。Step 6. When the difference is greater than the set threshold, a clogging prompt of the lint filter is issued.
若差值ΔT=T1-T2>T3，说明在关闭加热器后，T2下降不够明显，说明风道循环存在异常，导致T2下降不正常，而不正常原因为线屑过滤器堵塞引起，此时发出线屑过滤器堵塞提示，提醒用户及时清理线屑过滤器。If the difference ΔT=T1-T2>T3, it means that after the heater is turned off, the drop of T2 is not obvious enough, indicating that there is an abnormality in the air duct circulation, resulting in an abnormal drop of T2, which is caused by the clogging of the lint filter. A clogging reminder of the lint filter is issued to remind the user to clean the lint filter in time.
下面以一个具体的实施例，对本发明提出的衣物处理装置的检测方法进行详细说明。The detection method of the laundry treatment device proposed by the present invention will be described in detail below with a specific embodiment.
如图2所示，本实施例包括以下步骤：As shown in Figure 2, this embodiment includes the following steps:
步骤S21：启动烘干程序，获取环境温度t。Step S21: start the drying program, and acquire the ambient temperature t.
在干衣机、洗涤烘干一体机的衣物处理装置启动烘干程序后，首先获取其周围的环境温度t。After the laundry processing device of the clothes dryer or the integrated washing and drying machine starts the drying program, the ambient temperature t around it is first obtained.
步骤S22：检测线屑过滤器的安装开关是否有断开一次再闭合的记录。Step S22: Detect whether the installation switch of the lint filter has a record of being disconnected once and then closed again.
在本实施例中，为衣物处理装置的线屑过滤器配置安装开关，该安装开关安装于线屑过滤器上和/或衣物处理装置安装线屑过滤器的结构件上，在线屑过滤器安装上时，该安装开关闭合，在线屑过滤器卸下时，该安装开关断开。In this embodiment, the installation switch is configured for the lint filter of the laundry treatment device, and the installation switch is installed on the lint filter and/or on the structural member on which the lint filter is installed in the laundry treatment device, and the lint filter is installed When on, the installation switch is closed, when the lint filter is removed, the installation switch is off.
也即，用户在卸下线屑过滤器对其实施清理，清理后再安装上的过程，存在安装开关断开后再闭合的状态改变，在本实施例中，衣物处理装置对安装开关的这种状态改变实施记录。That is to say, when the user removes the lint filter and cleans it, and then installs it after cleaning, there is a state change in which the installation switch is turned off and then closed. A status change implementation record.
在烘干程序启动初，本实施例启动检测进程，对记录进行查询，判断判断线屑过滤器近期是否存在断开并再次闭合的状态改变记录，若存在该记录，说明用户近期刚清理过线屑过滤器，基本不存在堵塞的可能性，则可以直接转入步骤S31，无需执行以下步骤，但若近期不存在断开并再次闭合的状态改变记录，则说明线屑过滤器在规定期限内没有被清理过，则进入步骤S23。At the beginning of the drying program, this embodiment starts the detection process, queries the records, and judges whether there is a state change record that the lint filter has been disconnected and closed again recently. If there is such a record, it means that the user has just cleaned the line recently. If there is basically no possibility of clogging in the lint filter, you can directly go to step S31 without performing the following steps, but if there is no record of state change of disconnection and re-closing in the near future, it means that the lint filter is within the specified time limit If it has not been cleaned, go to step S23.
在本实施例中，还针对线屑过滤器的安装开关断开再闭合一次的状态改变，再提出一个容忍区间，在该容忍区间内，也无需启动后续的检测，直接执行烘干程序，例如：In this embodiment, a tolerance interval is also proposed for the state change of the installation switch of the lint filter when it is turned off and then closed again. In this tolerance interval, there is no need to start subsequent detection, and the drying program is directly executed, for example :
1、预设次数：在线屑过滤器的安装开关断开一次再闭合之后，累计烘干次数，在检测线屑过滤器的安装开关存在断开一次再闭合的记录时，判断累计烘干次数是否在预设次数之内，若是，则跳过下述步骤执行烘干程序；若否，则执行下述步骤，并将累计烘干次数清零。1. Preset times: After the installation switch of the lint filter is disconnected once and then closed again, the accumulated drying times will be determined. Within the preset number of times, if yes, skip the following steps to execute the drying program; if not, execute the following steps, and clear the accumulated drying times.
或者，2、预设重量：在线屑过滤器的安装开关断开一次再闭合之后，累计烘干衣物总量，在检测线屑过滤器的安装开关存在断开一次再闭合的记录时，判断累计的烘干衣物总量是否在预设重量之内，若是，则跳过下述步骤执行烘干程序；若否，则执行下述步骤，并将累计烘干衣物总量清零。Or, 2. Preset weight: After the installation switch of the lint filter is disconnected once and then closed again, the total amount of dried clothes will be accumulated. When the installation switch of the lint filter is detected to be disconnected once and then closed again, the accumulated weight will be judged. Whether the total amount of dried clothes is within the preset weight, if yes, skip the following steps and execute the drying program; if not, perform the following steps, and reset the accumulated total amount of dried clothes to zero.
步骤S23：根据环境温度确定线屑过滤器出风侧的温度基准T0。Step S23: Determine the temperature reference T0 of the air outlet side of the lint filter according to the ambient temperature.
本实施例以环境温度为20℃为例，则参考表一内容，可确定温度基准为72℃。In this embodiment, the ambient temperature is 20° C. as an example, and referring to the content in Table 1, it can be determined that the temperature reference is 72° C.
步骤S24：烘干程序运行10分钟后，获取线屑过滤器出风侧的第一检测温度T1。Step S24: After the drying program runs for 10 minutes, obtain the first detected temperature T1 of the air outlet side of the lint filter.
烘干程序持续运行10分钟后，衣物处理装置获取线屑过滤器出风侧的温度：第一检测温度T1，假设其为74℃。After the drying program continues to run for 10 minutes, the clothes processing device acquires the temperature of the air outlet side of the lint filter: the first detected temperature T1, which is assumed to be 74°C.
步骤S25：比较第一检测温度与确定的温度基准。Step S25: comparing the first detected temperature with the determined temperature reference.
比较第一检测温度T1和基准T0，74℃>72℃，第一检测温度高于温度基准，则进入步骤S25。Comparing the first detected temperature T1 with the reference T0, if 74°C>72°C, if the first detected temperature is higher than the temperature reference, then go to step S25.
若第一检测温度与温度基准T0相同或基本相同，则转入步骤S31。If the first detected temperature is the same or substantially the same as the temperature reference T0, go to step S31.
步骤S26：关闭加热器并维持风机运转。Step S26: Turn off the heater and keep the blower running.
通过风机维持运转实施降温。The cooling is implemented by maintaining the operation of the fan.
步骤S27：获取线屑过滤器出风侧的第二检测温度T2，计算第一检测温度T1与第二检测温度T2的差值。Step S27: Obtain the second detected temperature T2 on the air outlet side of the lint filter, and calculate the difference between the first detected temperature T1 and the second detected temperature T2.
关闭加热器维持风机运转期间，风道温度逐渐下降，可按照设定频率，例如1分钟1次，获取线屑过滤器出风侧的温度，作为第二检测温度T2，并比较第一检测温度T1和第二检测温度T2，得到差值ΔT=T1-T2。When the heater is turned off and the fan is running, the temperature of the air duct decreases gradually. The temperature of the air outlet side of the lint filter can be obtained according to the set frequency, such as once a minute, as the second detection temperature T2, and compared with the first detection temperature T1 and the second detected temperature T2, the difference ΔT=T1-T2 is obtained.
设定一个阈值T3，该设定阈值T3旨在表征在设定时间内，若风道畅通，也即线屑过滤器没有堵塞的情况下，温度正常下降的范围；可通过经验统计得到，或通过温降与时间关系得到，本实施例不予具体限定。Set a threshold T3, the set threshold T3 is intended to characterize the normal temperature drop range within the set time, if the air duct is unblocked, that is, the lint filter is not blocked; it can be obtained through empirical statistics, or It is obtained through the relationship between temperature drop and time, and is not specifically limited in this embodiment.
步骤S28：判断差值ΔT是否小于设定阈值T3。Step S28: Judging whether the difference ΔT is smaller than the set threshold T3.
若差值ΔT=T1-T2≤T3，说明在关闭加热器后，T2下降明显，说明风道循环基本正常，线屑过滤器堵塞的可能性不大，转入步骤S31，否则，说明在关闭加热器后，T2下降不够明显，说明风道循环存在异常，导致T2下降不正常，而不正常原因为线屑过滤器堵塞引起转入步骤S29。If the difference ΔT=T1-T2≤T3, it means that after turning off the heater, T2 drops significantly, indicating that the air duct circulation is basically normal, and it is unlikely that the lint filter is clogged. Go to step S31; After the heater, the T2 drop is not obvious enough, indicating that the air duct circulation is abnormal, resulting in an abnormal drop of T2, and the reason for the abnormality is that the lint filter is blocked and the process goes to step S29.
步骤S29：判断关闭加热器后是否到达设定时间。Step S29: judging whether the set time is reached after turning off the heater.
本实施例在关闭加热器并维持风机运转后，在一个设定时间内去按照设定频率获取线屑过滤器出风侧的第二检测温度，计算第一检测温度与第二检测温度的差值，通过设定时间的限定，给降温一个检测过程，若超出该设定时间，第一检测温度与降温后的第二检测温度的差值仍旧大于设定阈值，则能够非常肯定线屑过滤器发生了堵塞，从而提高对线屑过滤器堵塞情况判断的准确性。In this embodiment, after the heater is turned off and the fan is kept running, the second detection temperature of the air outlet side of the lint filter is obtained within a set time according to the set frequency, and the difference between the first detection temperature and the second detection temperature is calculated Value, through the limit of the set time, a detection process is given for the cooling. If the set time is exceeded, the difference between the first detection temperature and the second detection temperature after cooling is still greater than the set threshold, and the lint filter can be very sure. The clogging of the filter occurs, thereby improving the accuracy of judging the clogging of the lint filter.
步骤S30：发出线屑过滤器堵塞提示。Step S30: Issue a clogging prompt of the lint filter.
在达到设定时间后，差值仍旧大于设定阈值T3，则发出线屑过滤器堵塞的提示，该提示包括但不限定于蜂鸣提示、控制面板显示提示、语音提示、和向用户终端发送提示等。After the set time is reached, if the difference is still greater than the set threshold T3, a prompt that the lint filter is blocked will be issued, which includes but is not limited to buzzer prompts, control panel display prompts, voice prompts, and sending to the user terminal Tips etc.
