Description

Technical Field

[0001] The present invention relates to the technical field of dry cleaning machine exhaust detection technology, and in particular to a dryer exhaust blockage sensing method, device, equipment and storage medium. Background Art

[0002] In a direct-exhaust clothes dryer, the outside air passes through the heater, heated to become high-temperature air, and the motor drives the fan to generate suction force, which is sucked into the drum. The motor rotates to drive the drum to rotate and stir. The high-temperature, low-humidity air absorbs the moisture contained in the wet clothes and becomes high-temperature, high-humidity air. It is sucked into the fan through the filter and directly discharged to the outside through the exhaust duct. Although there is a lint filter at the air outlet in the dryer barrel, the fine lint cannot be completely filtered. After long-term use, the lint accumulates in the exhaust duct and causes blockage, resulting in poor exhaust. Moreover, due to the installation method of the exhaust duct connecting to the outdoors, it is difficult for users to detect and check its blockage, which not only affects the drying efficiency, but also poses a safety hazard. Usually, the user is set to be reminded of exhaust blockage after using a fixed number of drying times, but because the number and type of clothes dried by the user are not fixed, this method often cannot accurately reflect the degree of blockage.

[0003] The commonly used method at present is to judge whether the air duct is blocked by the change of the heater temperature sensor within a fixed drying time. This can only judge the blockage of the filter, but cannot specifically judge whether the exhaust channel is blocked. And if the temperature changes abnormally when the drying clothes cover the filter, this method will misjudge.

[0004] It can be seen that how to improve the accuracy of judging the blockage of the exhaust duct of the dry cleaning machine is a problem to be solved in this field. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a method, device, equipment and storage medium for sensing exhaust blockage of a clothes dryer, which detects the temperature changes of the exhaust duct and the heating duct according to the working state of the heater, and then determines the blockage of the exhaust duct, thereby improving the accuracy of exhaust blockage judgment.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] See also Figure 1 As shown, an embodiment of the present invention discloses a method for sensing exhaust blockage of a clothes dryer, comprising:

[0052] Step S11, when the heater of the dry cleaning machine is in working state, recording a first time period used when the first temperature of the exhaust passage of the dry cleaning machine rises to a first preset temperature.

[0053] In the present application, the temperature change of the exhaust duct of the dry cleaning machine when the heater is working is first detected, and the first time period used for the process from the heater starting to work to the first temperature rising to the first preset temperature corresponding to the exhaust duct can be recorded. In a specific embodiment, when the heater of the dry cleaning machine is in working state, recording the first time period used for the first temperature of the exhaust duct of the dry cleaning machine to rise to the first preset temperature can include: when the heater of the dry cleaning machine is in working state, detecting the first temperature of the exhaust duct of the dry cleaning machine through the first temperature sensor; if the first temperature rises to the first preset temperature, storing the current first time point, and calculating the time difference according to the first time point and the start time point when the heater is started, so as to obtain the first time period. Specifically, when the heater of the dry cleaning machine is in working state, the first temperature of the exhaust duct is constantly detected by the first temperature sensor; it can be understood that as the heater works, the temperature of the exhaust duct will also rise accordingly, and the time difference from the start time point to the current first time point of the heater can be calculated according to the first time point when the first temperature of the exhaust duct rises to the first preset temperature, so as to obtain the first time period.

[0054] Step S12: If the first temperature of the exhaust channel rises to the first preset temperature, the heater is adjusted to a non-working state, and the second temperature of the heating channel of the current dry cleaning machine is detected.

[0055] Further, when the first temperature of the exhaust duct rises to the first preset temperature, the heater can be turned off, that is, the heater is adjusted to a non-working state; at this time, it is necessary to detect the second temperature of the heating channel of the dry cleaning machine; in a specific embodiment, the detection of the second temperature of the heating channel of the current dry cleaning machine may include: detecting the second temperature of the heating channel of the current dry cleaning machine through a second temperature sensor; correspondingly, the detection of the fourth temperature of the current heating channel may include: detecting the fourth temperature of the current heating channel through the second temperature sensor. Specifically, the second temperature sensor may be used to detect the temperature corresponding to the heating duct. It can be understood that when the first temperature of the exhaust duct rises to the first preset temperature, the temperature corresponding to the heating duct is the second temperature.

[0056] Step S13: when the heater is in the non-working state, record the second time period used when the third temperature of the exhaust channel drops to the second preset temperature, and detect the fourth temperature of the current heating channel.

[0057] In the present application, it can be understood that after the heater is adjusted to a non-working state, the temperature of the dry cleaning machine will gradually decrease; during this process, the second time period used for the temperature of the exhaust duct to drop from the first temperature to the second preset temperature can be recorded; and at this time, it is necessary to detect the fourth temperature corresponding to the heating channel; it can be understood that when the temperature of the exhaust duct drops to the second preset temperature, the temperature corresponding to the heating duct is the fourth temperature.

[0058] In a specific embodiment, when the heater is in the non-operating state, recording the second time period used when the third temperature of the exhaust duct drops to the second preset temperature may include: when the heater is in the non-operating state, detecting the third temperature of the exhaust duct by the first temperature sensor; if the third temperature drops to the second preset temperature, storing the current second time point, and calculating the time difference between the second time point and the first time point to obtain the second time period. Specifically, when the heater is in the non-operating state, the third temperature of the exhaust duct may be constantly detected by the first temperature sensor, and when the third temperature gradually drops to the second preset temperature, the current second time point is stored, and based on the aforementioned second time point, the time difference between the temperature of the exhaust duct dropping from the first temperature to the third temperature may be calculated to obtain the second time period.

[0059] Step S14: based on a preset dry cleaning machine exhaust blockage parameter threshold, and in combination with the first time period, the second time period, the second temperature and the fourth temperature, determine the blockage condition of the exhaust passage.

[0060] In the present application, the first time period, the second time period, the second temperature and the fourth temperature can be obtained through the above steps, and then the exhaust duct of the current dry cleaning machine can be judged whether there is a blockage according to the preset dry cleaning machine exhaust blockage parameter threshold. In a specific embodiment, the blockage of the exhaust passage is judged based on the preset dry cleaning machine exhaust blockage parameter threshold and in combination with the first time period, the second time period, the second temperature and the fourth temperature, and can include: if the first time period is greater than the first time threshold in the preset dry cleaning machine exhaust blockage parameter threshold, the exhaust passage is judged to be unblocked; if the first time period is not greater than the first time threshold in the preset dry cleaning machine exhaust blockage parameter threshold, then it is judged whether the second time period is greater than the second time threshold in the preset dry cleaning machine exhaust blockage parameter threshold; if the second time period is greater than the second time threshold in the preset dry cleaning machine exhaust blockage parameter threshold, then it is judged that the exhaust passage is unblocked; if the second time period is not greater than the second time threshold in the preset dry cleaning machine exhaust blockage parameter threshold, then the blockage of the exhaust passage is judged based on the preset parameter calculation formula and in combination with the first time period, the second temperature, the fourth temperature and the blockage parameter range in the preset dry cleaning machine exhaust blockage parameter threshold. Specifically, when the first time period is greater than the first time threshold in the preset dry-cleaner exhaust blockage parameter threshold, the exhaust duct can be determined to be unblocked; correspondingly, when the first time period is not greater than the first time threshold, it means that the exhaust duct can only be determined to be unblocked based on the first time period alone. Further, in order to improve the accuracy of the result, the second time period can be compared with the second time threshold in the preset dry-cleaner exhaust blockage parameter threshold. It can be understood that when the heater is not working, the temperature will gradually drop. If the exhaust is blocked, the temperature of the exhaust duct will drop faster. Therefore, when the second time period is greater than the second time threshold, the exhaust duct is determined to be unblocked. Correspondingly, when the second time period is not greater than the second time threshold, in order to improve the accuracy of the result, the present application can further determine whether the exhaust duct is blocked according to the preset parameter calculation formula.

[0061] In a specific embodiment, the method of judging the blockage of the exhaust passage based on the preset parameter calculation formula and in combination with the first time period, the second temperature, the fourth temperature and the preset dry cleaning machine exhaust blockage parameter threshold value may include: calculating the blockage parameter of the dry exhaust passage based on the preset parameter calculation formula and in combination with the first time period, the second temperature and the fourth temperature; if the blockage parameter is not greater than the lower limit of the blockage parameter range, it is determined that there is no blockage in the exhaust passage; if the blockage parameter is within the blockage parameter range, it is determined that the exhaust passage is slightly blocked; if the blockage parameter is not less than the upper limit of the blockage parameter range, it is determined that the exhaust passage is severely blocked. Specifically, according to the preset parameter calculation formula, the blockage parameter of the exhaust duct can be calculated using the first time period, the second temperature and the fourth temperature; further, if the blockage parameter is not greater than the lower limit of the blockage parameter range, it can be determined that there is no blockage in the exhaust duct; if the blockage parameter is within the blockage parameter range, it is determined that there is slight blockage in the exhaust duct; if the blockage parameter is greater than the upper limit of the blockage parameter range, it is determined that there is severe blockage in the exhaust duct.

[0062] In a specific embodiment, it may also include: displaying the blockage of the dry cleaning machine through a preset human-machine interaction panel so that the user can take corresponding countermeasures according to the blockage. Specifically, in the process of detecting whether the exhaust duct is blocked, the blockage of the dry cleaning machine can be displayed through the preset human-machine interaction panel, and the temperature change of the exhaust duct and the heating duct, the working state of the heater and the working time can be displayed; this is convenient for users or staff to check the condition of the dry cleaning machine and take corresponding countermeasures in time.

[0063] It can be seen that the present application can detect the changes in the temperature of the exhaust duct of the dry cleaning machine when the heater is working and not working, as well as the change time period, and can detect the temperature changes of the heating duct in the corresponding time period; then the blockage condition of the exhaust duct is judged according to the temperature of the exhaust duct and the temperature changes of the heating duct, and the accurate exhaust blockage result can be determined according to the preset dry cleaning machine exhaust blockage parameter threshold, which can avoid the influence of clothing covering on the judgment result, and improve the accuracy of the exhaust blockage judgment result.

[0064] like Figure 2 As shown, the embodiment of the present application discloses a method for sensing exhaust blockage of a clothes dryer, comprising:

[0065] In the present application embodiment, Figure 3As shown, temperature sensor 1 can detect the temperature of the exhaust duct, and temperature sensor 2 can detect the temperature of the heating duct. When the heater of the dry cleaning machine starts working, turn on the timer (starting from zero); then when temperature sensor 1 (first temperature sensor) detects that the current temperature (first temperature) of the exhaust duct is greater than the heating target temperature Ta (first preset temperature), the current moment is recorded as ti (representing the first time period) according to the timer, and the current temperature (second temperature) of the heating duct detected by temperature sensor 2 (second temperature sensor) is recorded as Ti, and the heater is turned off. It can be understood that after the heater is turned off, the temperatures of the exhaust duct and the heating duct of the dry cleaning machine will gradually decrease. When temperature sensor 1 detects that the current temperature (third temperature) of the exhaust duct is less than the heating restart temperature Tb (second preset temperature), the current moment is recorded as te (te-ti represents the second time period), and the current temperature (fourth temperature) of the heating duct is detected as Te by temperature sensor 2, and the heater is restarted at the same time. As shown Figure 4 The figure shows the curve of the temperature change of the heating pipe of the dry cleaning machine over time. It should be pointed out that if the exhaust pipe is blocked, after the drying process heating is turned on, the high-temperature and high-humidity air gathers quickly to the temperature sensor 1, and the heater reaches the target temperature quickly, that is, ti is small. Due to the poor air supply, the drum inlet temperature is relatively high, that is, Ti is large, and the temperature changes less with the start and stop of the heater after reaching the target temperature, that is, te-ti is small. After the heater is turned off, the low-temperature and high-humidity gas in the exhaust channel flows back to the temperature sensor 1, and the heater is repeatedly turned off (closed) and on (opened) more frequently, that is, Te-Ti is small. Afterwards, the blockage condition of the exhaust duct of the dry cleaning machine can be judged according to the temperature and time parameters obtained in the above steps. Specifically, if the time ti is greater than the first time threshold t in the preset dry cleaning machine exhaust blockage parameter threshold, the exhaust blockage degree Level is judged to be 0 (not blocked); correspondingly, if ti is less than t, it can be further judged whether te-ti is less than the second time threshold t (the first time threshold and the second time threshold are set according to actual conditions, and can be the same or different). If te-ti is less than the second time threshold t, it is judged that the exhaust duct is not blocked; if te-ti is not less than the second time threshold t, it can be further judged whether the exhaust duct is blocked according to the preset parameter calculation formula. Specifically, the parameter Y can be calculated according to the formula Y=Ti / ti / (Ti-Te), and then the size relationship between Y and the preset parameter threshold range (L1, L2) can be determined. If Y is less than the lower limit L1 of the parameter threshold range, it is determined that the exhaust duct is not blocked. If Y is greater than L1 and less than L2, the blockage level of the exhaust duct is determined to be Level 1 (mild blockage). Furthermore, when Y is not less than L2, the blockage level of the exhaust duct is determined to be Level 2 (severe blockage). At this time, the drying can be suspended, and the user can start the heater of the dry cleaning machine after handling the blockage.

[0066] It can be seen that the present application can simultaneously consider the temperature changes of the exhaust duct and the heating duct. When the temperature of the exhaust duct reaches the corresponding target temperature, the temperature of the heating duct is detected. According to the working state of the heater, each temperature and time parameter is judged separately, so as to accurately judge the blockage condition of the exhaust duct and improve the reliability of the blockage perception result.
