Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smart home appliances, and specifically provides a control method for a clothes drying device. BACKGROUND

[0002] With the improvement of people's living standards, people pay more attention to the quality of clothes. However, in the plum rain season, the rainy air humidity is large, so that the washed clothes are difficult to dry quickly, resulting in the generation of peculiar smell on the clothes, breeding of bacteria such as mold, staphylococcus aureus, candida albicans, etc., which greatly affects the user experience.

[0003] In order to solve the above problems, in the prior art, the air washing method is used to remove the peculiar smell of clothes. The existing air washing is to inject water into the outer cylinder, generate steam by heating the water at the bottom of the outer cylinder to steam wash the clothes in the inner cylinder, and generate hot air by the drying system and blow the hot air into the inner cylinder to care for the clothes in the inner cylinder. However, the steam washing method has too low a humidification efficiency for clothes, and if the moisture content of the clothes does not reach the preset moisture content, the deodorizing effect of the clothes will be affected, and even the clothes will be damaged, which is not conducive to the user experience.

[0012] In the preferred technical solution of the control method, the step of selectively stopping the operation of the clothes drying device according to the judgment result specifically comprises: if the current total concentration is less than the second preset concentration, the operation of the clothes drying device is stopped; and / or if the current total concentration is greater than or equal to the second preset concentration, the clothes drying device continues to perform the deodorization operation.

[0013] In the preferred technical solution of the control method, the operation parameter comprises a heating time and / or a heating power.

[0014] In the preferred technical solution of the control method, after the heating module is started, the control method further comprises: acquiring the temperature in the clothes drying drum; judging whether the temperature reaches a target deodorization temperature; if the temperature reaches the target deodorization temperature, controlling the heating module to stop heating; acquiring the temperature in the clothes drying drum again; judging whether the temperature acquired again is lower than a preset temperature; if the temperature acquired again is lower than the preset temperature, starting the heating module again.

Those skilled in the art can flexibly set the specific structure of the drying system in actual application, as long as the drying system can deodorize and dry clothes. The control method of the present application is further described below with the condensing structure as an example.

[0038] Preferably, the heating module of the present application can be the heater of the condensing structure described above, or the condenser of the heat pump structure described above. Further, the number of the heater or the condenser can be one, two or more.

[0039] Preferably, the water outlet is in communication with the front part (the part close to the window gasket of the dryer) of the outer cylinder through a pipeline, a spray head is arranged at the connection end of the pipeline and the outer cylinder, and the spray head faces the inside of the inner cylinder; the connection end of the pipeline and the water outlet is provided with a motor, a pump and a valve for controlling water supply and spraying to the spray head.

[0040] Further, the dryer is provided with a communication module such as a Bluetooth module, a WiFi module, an NFC module and a ZigBee module, and the dryer can be in communication connection with a server through the communication module.

[0041] Next, the control method of the present application is described. Figure 1 The control method of the present application is described. Figure 1 is the flow of the control method of the present application Figure 1 .

[0042] As shown in Figure 1 , the control method of the present application includes the following steps:

[0043] S100, making the dryer perform a spraying operation;

[0044] S200, acquiring the humidity of the clothes in the drying cylinder during the spraying operation of the dryer;

[0045] S300, judging whether the humidity reaches a preset humidity;

[0046] S400, in the case where the humidity reaches the preset humidity, obtaining components of odor gas in the drying drum;

[0047] S500, obtaining initial concentrations of different odor gases in the drying drum;

[0048] S600, obtaining initial total concentration of odor gas in the drying drum;

[0049] S700, according to the components, the initial concentrations and the initial total concentration, making the drying machine perform the drying and odor removal operation.

[0050] In step S100, the spraying operation is performed after the user puts the clothes into the inner drum and it is detected that the door body is locked. Further, the spraying operation is performed in the case of selecting the intelligent humidifying drying and odor removal program. Specifically, the motor and the pump are started, the valve is opened, and water is supplied to the spray head, so that the spray head sprays water into the inner drum.

[0051] In step S200, during the spraying operation of the drying machine, the humidity of the clothes in the drying drum is detected in real time by the humidity sensor, or the humidity of the clothes in the drying drum is detected at a first preset time interval, for example, 5s, 10s or 15s, etc. Those skilled in the art can flexibly adjust and set the first preset time interval according to the actual spraying effect in practical application, and the present application does not make any limitation thereto.

[0052] Further, during the spraying operation of the drying machine, the inner drum is rotated, for example, forward rotation, reverse rotation, forward and reverse rotation alternately, or rotation by a preset angle, so that the spraying water mist can fully cover the clothes, can fully wet the clothes, avoid the situation that part of the clothes is not wet, and is more conducive to making the clothes soft, thus being more conducive to removing the odor on the clothes as soon as possible.

[0053] In steps S400 to S700, in the case where the humidity reaches the preset humidity, for example, the preset humidity is 10%, and the detected humidity is 12%, which is greater than the preset humidity, it indicates that the current humidity of the clothes is large enough, and the drying and odor removal operation performed at this humidity will not cause damage to the clothes, then the components of odor gas in the drying drum, the initial concentrations of different odor gases in the drying drum and the initial total concentration of odor gas in the drying drum are obtained, and according to the components, the initial concentrations and the initial total concentration, the drying machine performs the drying and odor removal operation. It should be noted that when the humidity of the clothes reaches 6%, the clothes can be dried, in order to improve the odor removal effect, the preset humidity is set to be greater than 6%, and those skilled in the art can flexibly adjust and set the preset humidity on this basis and in combination with the actual concentration of odor gas and the odor removal demand, etc.

[0054] Further, the components of the odor gas in the drying cylinder, the initial concentrations of different odor gases in the drying cylinder, and the initial total concentration of the odor gas in the drying cylinder are detected by the odor sensor. For example, other sensors such as air quality sensors and odor sensors.

[0055] The components of the odor gas include, but are not limited to, methyl mercaptan, trimethylamine, and formaldehyde.

[0056] Alternatively, different sensors can be used to detect the initial concentrations of different odor gases, such as methyl mercaptan sensors, trimethylamine sensors, and formaldehyde sensors to detect the initial concentrations of odor gases such as methyl mercaptan, trimethylamine, and formaldehyde, i.e., c1, c2, and c3. The sum of the detected initial concentrations is calculated, and the calculated sum of the initial concentrations is taken as the initial total concentration Co of the odor gas.

[0057] Further, during the drying and deodorizing operation of the drying machine, the inner drum is rotated, for example, forward, reverse, alternating forward and reverse rotation, or rotated by a predetermined angle, so that the hot air can fully cover the clothes, avoiding the situation that some parts are not covered by the hot air, and more conducive to removing the odor from the clothes as soon as possible.

[0058] Further, in the case where the humidity does not reach the preset humidity, step S800 is performed;

[0059] S800, the drying machine continues to perform the spraying operation until the humidity of the clothes reaches the preset humidity, avoiding damage to the clothes during the drying and deodorizing process, and improving the user experience.

[0060] It should be noted that in the above process, the execution order of steps S400 to S600 is not limited to the order listed above. Steps S500 can be performed first, followed by steps S400 and S600, or steps S400 to S600 can be performed simultaneously. Those skilled in the art can flexibly adjust and set the execution order of steps S400 to S600. Steps S400 and S800 have no sequence and are parallel, and are only related to the judgment result of whether the humidity reaches the preset humidity. According to different judgment results, the corresponding steps can be executed.

[0061] It should be noted that although the above embodiment is described in combination with step S800, the above steps are not necessarily required. Those skilled in the art can understand that, under the premise of ensuring the normal operation of the control method, the above steps can be appropriately reduced to combine a new embodiment. For example, step S800 can be deleted based on the above embodiment to combine a new control method.

[0062] The following refers to Figures 2 to 4The control method for making the clothes dryer perform the drying and odor removal operation is described. Figure 2 is a flowchart of the control method for making the clothes dryer perform the drying and odor removal operation of the present application; Figure 3 is a flowchart of the control method for determining the operation parameters of the present application;

[0063] Figure 4 is a flowchart of the control method for determining the second target odor removal temperature of the present application.

[0064] As shown in Figure 2 , the step of "making the clothes dryer perform the drying and odor removal operation according to the component, the initial concentration and the initial total concentration" in step S700 specifically includes:

[0065] S711, determining whether the initial total concentration is greater than a first preset concentration;

[0066] S712, selectively determining the operation parameters of the heating module of the clothes dryer according to the component and the initial concentration or the material of the clothes according to the determination result;

[0067] S713, starting the heating module and controlling the heating module to operate according to the operation parameters to generate hot air;

[0068] S714, controlling the circulating fan of the clothes dryer to blow the hot air into the drying drum so as to dry and remove odor from the clothes in the drying drum.

[0069] The operation parameters include the heating time and the heating power. Of course, the operation parameters can only include the heating time or the heating power.

[0070] The above method can determine the operation parameters of the heating module for different kinds of odor gas with different components or clothes with different materials to generate different hot air, which can more effectively remove odor from the clothes and avoid damaging the clothes during the drying and odor removal process, further improving the care effect of the clothes.

[0071] As shown in Figure 3 , the step of "selectively determining the operation parameters of the heating module of the clothes dryer according to the component and the initial concentration or the material of the clothes according to the determination result" in step S712 specifically includes:

[0072] S721, if the initial total concentration is less than or equal to the first preset concentration, sending the material to the server to make the server determine the first target odor removal temperature according to the material;

[0073] S722, receiving the first target odor removal temperature from the server;

[0074] S723, determine the operation parameter according to the first target odor removal temperature.

[0075] In step S721, if the initial total concentration is less than or equal to the first preset concentration, for example, the first preset concentration is 0.5 g / L, and the initial total concentration of the detected odor gas is 0.2 g / L, which is less than the first preset concentration, it indicates that the initial total concentration of the odor gas is low, and only the normal odor removal operation needs to be performed on the clothes. Therefore, the material of the clothes is sent to the server, so that the server can more accurately determine the first target odor removal temperature according to the material.

[0076] Further, the material of the clothes can be detected by a clothes sensor, or an image of the clothes can be captured to determine the material of the clothes according to the image, or an RFID tag of the clothes can be scanned to determine the material of the clothes according to the scanning result. The RFID tag includes the material, color, type, and washing method of the clothes. As long as the material of the clothes can be determined, any method can be used.

[0077] For example, the material of the clothes is cotton, the maximum drying temperature of cotton is 50°C, and 50°C is determined as the first target odor removal temperature, which ensures that all the small amount of odor gas is removed, and avoids damage to the clothes during the drying and odor removal process, further improves the care effect of the clothes, and improves the user experience.

[0078] For example, there are two clothes, and the materials of the clothes are silk and cashmere respectively. The maximum drying temperature of silk is 45°C, and the maximum drying temperature of cashmere is 35°C. Comparing 45°C and 35°C, it can be known that 35°C is the lowest temperature. Therefore, 35°C is determined as the first target odor removal temperature, which ensures that all the small amount of odor gas is removed, and avoids damage to the clothes during the drying and odor removal process, further improves the care effect of the clothes, and improves the user experience.

[0079] In step S723, the clothes dryer determines the heating time and heating power of the heating module according to the first target odor removal temperature (for example, 35°C) received from the server, for example, heating for 40 minutes, starting a heater to generate hot air for removing odor on the material, so that the odor on the clothes can be more effectively removed.

[0080] Further, the heating power of the heating module can be changed by changing the number of started heaters.

[0081] Referring back to Figure 3 , in step S712, the step of "determining the operation parameter of the heating module of the clothes dryer selectively according to the components and the initial concentration or the material of the clothes according to the judgment result" further includes:

[0082] S724, if the initial total concentration is greater than the first preset concentration, sending the component and the initial concentration to the server to make the server determine the second target odor removal temperature according to the component and the initial concentration;

[0083] S725, receiving the second target odor removal temperature from the server;

[0084] S726, determining the operation parameter according to the second target odor removal temperature;

[0085] In step S724, if the initial total concentration is greater than the first preset concentration, for example, the first preset concentration is 0.5 g / L, and the initial total concentration of the odor gas detected is 0.6 g / L, which is greater than the first preset concentration, it indicates that the initial total concentration of the odor gas is high, and special odor removal operation needs to be performed according to the component of the odor gas. Therefore, the component and the initial concentration are sent to the server to make the server more accurately determine the second target odor removal temperature according to the component and the initial concentration.

[0086] In step S726, the clothes dryer determines the heating time and the heating power of the heating module according to the second target odor removal temperature received from the server to generate hot air for removing the odor gas of the component, so that the odor on the clothes can be more effectively removed.

[0087] Further, the heating power of the heating module can be changed by changing the number of started heaters.

[0088] Preferably, as shown in the figure, the step of "sending the component and the initial concentration to the server to make the server determine the second target odor removal temperature according to the component and the initial concentration" in step S721 specifically includes: Figure 4

[0089] S731, sending the material to the server;

[0090] S732, to make the server determine the highest odor removal temperature according to the component and the initial concentration;

[0091] S733, to make the server determine the highest drying temperature of the clothes according to the material;

[0092] S734, to make the server compare the highest odor removal temperature and the highest drying temperature;

[0093] S735, to make the server determine the minimum value according to the comparison result;

[0094] S736, to make the server determine the minimum value as the second target odor removal temperature.

[0095] The following further illustrates the case where the components of the odor gas include methyl mercaptan, trimethylamine and formaldehyde. ​

[0096] For example, the initial concentration of methyl mercaptan is 0.3 g / L, and the first minimum odor-removing temperature of methyl mercaptan is determined based on the initial concentration of methyl mercaptan, which is 35°C; the initial concentration of trimethylamine is 0.1 g / L, and the second minimum odor-removing temperature of trimethylamine is determined based on the initial concentration of trimethylamine, which is 40°C; the initial concentration of formaldehyde is 0.2 g / L, and the third minimum odor-removing temperature of formaldehyde is determined based on the initial concentration of formaldehyde, which is 45°C; 35°C, 40°C and 45°C are compared, and it can be known from the comparison that 45°C is the highest temperature, so 45°C is determined as the highest odor-removing temperature, ensuring that the three odor gases of methyl mercaptan, trimethylamine and formaldehyde can all be removed.

[0097] Further, the server determines the highest drying temperature of the clothes according to the material, for example, the material of the clothes is cotton, and the highest drying temperature of the cotton is 50°C; 50°C (i.e. the highest drying temperature) and 45°C (i.e. the highest odor-removing temperature) are compared, and it can be known from the comparison that 45°C is the minimum value, so 45°C is determined as the second target odor-removing temperature, ensuring that the three odor gases of methyl mercaptan, trimethylamine and formaldehyde can all be removed, and damage to the clothes in the drying and deodorizing process is avoided, further improving the care effect of the clothes and enhancing the user experience.

[0098] For example, in step S726, the heating time determined according to 45°C is 50 min, and two heaters are started.

[0099] Alternatively, the material of the clothes is cashmere, and the highest drying temperature of the cashmere is 35°C; 35°C (i.e. the highest drying temperature) and 45°C (i.e. the highest odor-removing temperature) are compared, and it can be known from the comparison that 35°C is the minimum value, so 35°C is determined as the second target odor-removing temperature, avoiding damage to the clothes in the drying and deodorizing process. Since the second target odor-removing temperature is reduced, in order to ensure that the three odor gases of methyl mercaptan, trimethylamine and formaldehyde can all be removed, the heating time needs to be extended, for example, the heating time is extended to 65 min, and only one heater needs to be started.

[0100] It should be noted that the initial concentration, the first preset concentration, the minimum odor-removing temperature, the highest odor-removing temperature and the highest drying temperature of the odor gas listed above are only exemplary and are not limited, and those skilled in the art can flexibly adjust and set the first preset concentration, the minimum odor-removing temperature, the highest odor-removing temperature and the highest drying temperature according to the initial concentration of the odor gas actually detected, the actual odor-removing process of the odor gas and the material of the clothes, etc.

[0101] It should be further noted that in the above process, the execution order of steps S732 and S733 is not limited to the order listed above, and step S733 can be executed first and then step S732 can be executed, or steps S732 and S733 can be executed simultaneously. Those skilled in the art can flexibly adjust and set the execution order of steps S732 and S733. Steps S721 and S724 have no sequence and are parallel, and are only related to the judgment result of whether the initial total concentration is greater than the first preset concentration. According to different judgment results, the corresponding steps can be executed.

[0102] In addition, although the above process is executed by the server to execute the steps of "determining the first target odor removal temperature according to the material" and "determining the second target odor removal temperature according to the component and the initial concentration", in actual application, the above two steps can also be executed by the clothes dryer. Those skilled in the art can flexibly adjust and set the execution subject of the above steps according to actual use requirements.

[0103] The control method of the present application will be further described below with reference to Figure 5 and Figure 6 . Among them, Figure 5 is the flowchart of the control method of the present application Figure 2 ; Figure 6 is the flowchart of the control method of selectively stopping the operation of the clothes dryer of the present application.

[0104] As Figure 5 shown, in the case where the initial total concentration is greater than the first preset concentration, during the execution of the drying and deodorizing operation of the clothes dryer, the control method further comprises:

[0105] S741, acquiring the current total concentration of odor gas in the drying drum;

[0106] S742, judging whether the current total concentration is less than the second preset concentration;

[0107] S743, selectively stopping the operation of the clothes dryer according to the judgment result.

[0108] In step S741, the current total concentration of odor gas in the drying drum is detected in real time by the above-mentioned odor sensor, or the current total concentration of odor gas in the drying drum is detected at a second preset time interval, for example, 4s, 8s or 12s, etc. Those skilled in the art can flexibly adjust and set the second preset time interval according to the actual deodorizing effect in actual application, and the present application does not make any limitation thereon.

[0109] As Figure 6 shown, in step S743, the step of "selectively stopping the operation of the clothes dryer according to the judgment result" specifically comprises:

[0110] S751, if the current total concentration is less than the second preset concentration, the drying machine is stopped running;

[0111] S752, if the current total concentration is greater than or equal to the second preset concentration, the drying machine continues to perform the drying and deodorizing operation.

[0112] In step S751, if the current total concentration is less than the second preset concentration, for example, the second preset concentration is 0.03 g / L, and the current total concentration of the detected odor gas is 0.01 g / L, which is less than the second preset concentration, it indicates that the odor gas has been basically removed, and there is no need to continue to perform the drying and deodorizing operation. Therefore, the heating module and the circulating fan are stopped running, and the drying machine is stopped running.

[0113] In step S752, if the current total concentration is greater than or equal to the second preset concentration, for example, the second preset concentration is 0.03 g / L, and the current total concentration of the detected odor gas is 0.05 g / L, which is greater than the second preset concentration, it indicates that the odor gas has not been removed. Therefore, the drying machine continues to perform the drying and deodorizing operation until the current total concentration detected again is less than the second preset concentration.

[0114] It should be noted that the above-mentioned current total concentration and second preset concentration are only exemplary and are not limited. Those skilled in the art can flexibly adjust and set the second preset concentration according to the actual detected current total concentration of the odor gas, the actual odor gas removal process, and the like in actual application.

[0115] It should be further noted that in the above process, step S751 and step S752 have no sequence and are parallel, and are only related to the judgment result of whether the current total concentration is less than the second preset concentration. According to different judgment results, the corresponding steps can be performed.

[0116] The control method of the present application will be further described below with reference to Figure 7 The control method of the present application will be further described below with reference to Figure 7 is the flow of the control method of the present application Figure 3 .

[0117] As shown in Figure 7 , after the heating module is started, the control method further comprises:

[0118] S761, obtaining the temperature in the drying drum;

[0119] S762, judging whether the temperature reaches a target deodorizing temperature; if yes, step S763 is performed; if no, step S768 is performed;

[0120] S763, controlling the heating module to stop heating;

[0121] S764, acquiring the temperature in the drying drum again;

[0122] S765, determining whether the acquired temperature is lower than the preset temperature; if yes, executing step S766; if no, executing step S767;

[0123] S766, starting the heating module again;

[0124] S767, not starting the heating module;

[0125] S768, continuing to run the heating module.

[0126] The target odor removal temperature is the first target odor removal temperature or the second target odor removal temperature determined in the above process. Specifically, the target odor removal temperature can be determined as the first target odor removal temperature or the second target odor removal temperature according to the determination result of whether the initial total concentration is greater than the first preset concentration.

[0127] The preset temperature is less than the target odor removal temperature.

[0128] In steps S761 and S764, the temperature in the drying drum is detected by a temperature sensor. Preferably, the temperature in the inner drum is detected. That is, when the temperature in the inner drum reaches the target odor removal temperature, the heating module stops running; when the temperature in the inner drum is lower than the preset temperature, the heating module starts running, and the cycle is repeated until the total running time of the heating module reaches the heating time.

[0129] Further, the total running time of the heating module can be the total time of starting and running the heating module, or can be the time counted from the first start of the heating module.

[0130] Hereinafter, the target odor removal temperature is taken as the first target odor removal temperature, i.e. 50℃, and the preset temperature is taken as 48℃ for further illustration. Of course, the preset temperature can also be other temperatures, such as 47℃, 45℃, etc., as long as the preset temperature is less than the target odor removal temperature.

[0131] If the detected temperature inside the inner drum is 45°C, the first target odor removal temperature is not reached, the heating module is allowed to continue to run to send hot air into the inner drum to increase the temperature inside the inner drum, and the temperature inside the inner drum is continuously detected. If the detected temperature inside the inner drum increases to 50°C, the first target odor removal temperature is reached, and in order to avoid the temperature being too high, the heating module is controlled to stop heating, and the temperature inside the inner drum is detected again. If the detected temperature inside the inner drum decreases to 47°C, which is lower than the preset temperature, it indicates that the temperature inside the inner drum is slightly low, and the heating module is started again to continue to send hot air into the inner drum to increase the temperature inside the inner drum. However, if the detected temperature inside the inner drum is 49°C, which is higher than the preset temperature, the heating module does not need to be started. In this way, the temperature inside the inner drum can be maintained between the target odor removal temperature and the preset temperature, so that the odor on the clothes can be effectively removed, and the care effect of the clothes is further improved.

[0132] It should be noted that in the above process, steps S763 and S768 have no sequence and are parallel, and are only related to the judgment result of whether the temperature reaches the target odor removal temperature, and the corresponding steps can be executed according to different judgment results. Steps S766 and S767 have no sequence and are parallel, and are only related to the judgment result of whether the temperature obtained again is lower than the preset temperature, and the corresponding steps can be executed according to different judgment results.
