Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing equipment, and in particular to a clothing processing equipment and a control method thereof. Background Art

[0002] With the continuous improvement of living standards, people's demand for laundry has been continuously refined, and the use of washing and drying machines or clothes dryers has become more and more widespread. However, there will be many problems in the drying process of clothing processing equipment, resulting in a poor user experience. For example, the accuracy of clothing processing equipment in drying dryness judgment (i.e. judging whether it is dry) is not high enough, resulting in the situation that the clothes may be partially damp when the user takes the clothes, and the clothes may need to be dried twice, or they may be over-dried. If the clothes are over-dried, the fabric fibers may be damaged.

[0003] Existing clothes processing equipment generally uses a temperature sensor to determine whether to dry clothes, that is, the dryness of clothes is determined by the wind temperature during drying. However, this judgment method still has certain defects. For example, this judgment method can only determine the wind temperature near the area where the temperature sensor is located. If there are too many clothes in the drying inner drum, or the clothes are not fully stretched out, the dryness judgment will be inaccurate, and the drying process will end when the clothes are not dried inside. Summary of the invention

[0046] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0047] See below Figure 1 The embodiment of the present invention provides a clothes processing device, including a drying inner drum 1, and the clothes processing device also includes:

[0048] The humidity sensing space 2 is communicated with the interior of the drying inner drum 1;

[0049] The moisture sensing material 3 is placed in the moisture sensing space 2 and is used to absorb moisture in the air and change different colors according to the content of the absorbed moisture;

[0050] An image detection device, used for collecting a color image of the hygroscopic substance 3;

[0051] The control module is connected to the image detection device, and is used to receive the color image sent by the image detection device, and judge the clothes drying state of the clothes processing device according to the color of the moisture-sensitive substance 3 in the color image.

[0052] In this embodiment, the clothes processing device includes a drying inner drum 1 and a humidity sensing space 2 connected to the drying inner drum 1. A humidity sensing material 3 is arranged in the humidity sensing space 2. The humidity sensing material 3 can absorb moisture in the air and change the corresponding color according to the amount of moisture absorbed, that is, different colors represent the humidity in the air and the moisture content of the clothes. At the same time, the clothes processing device also includes an image detection device for taking an image of the humidity sensing material 3, such as a camera or other devices, which not only improves the circulation and uniformity of the hot and humid air, but also allows the humidity sensing material 3 to fully contact the hot and humid air in the drying inner drum 1, thereby allowing the humidity sensing material 3 to change color after absorbing or desorbing moisture, and the image detection device can detect the color change of the humidity sensing material 3, and thereby determine the air humidity level of the drying inner drum 1 in the clothes processing device, and then determine the degree of dryness of the clothes in the drying inner drum 1.

[0053] In this embodiment, the image detection device 4 detects the color image of the moisture-sensitive material 3 in the drying inner drum 1 to obtain the air humidity level and the degree of dryness of the clothes in the drying inner drum 1, so that the dryness and drying process of the clothes can be effectively and accurately judged, thereby solving the problem of insufficient accuracy of the clothes processing equipment in judging the drying process and improving the drying control effect of the clothes processing equipment. In addition, after the clothes are washed and the washing machine is in an idle state, the moisture-sensitive material 3 can also absorb the moisture in the air of the drying inner drum 1 to keep the inner drum dry and reduce mold and odor.

[0054] In a specific embodiment, the composition of the hygroscopic material 3 includes cobalt chloride. Specifically, the hygroscopic material 3 can be a hygroscopic color-changing particle composed of color-changing silica gel. The initial color of the hygroscopic color-changing particle is blue. According to the shape of the particles, it can be divided into two types: spherical and blocky. Its main component is cobalt chloride. Cobalt chloride has a strong adsorption effect on water vapor in the air, and can also show different colors by changing the amount of cobalt chloride crystal water contained. As shown in Table 1 below, the initial color of the hygroscopic color-changing particles before moisture absorption is blue, and gradually changes from blue to light red with the increase of moisture absorption. At the same time, the hygroscopic color-changing particles adsorb water vapor or other organic substances in the medium during use, resulting in a decrease in adsorption capacity, so the moisture can be removed by thermal desorption for reuse. In other optional embodiments, there are other hygroscopic color-changing properties that can be used as the hygroscopic material 3 described in this embodiment, such as silicon dioxide, water-absorbing color-changing resin, etc.

[0056] Table 1

[0057] In practical applications, combined with Figure 3In the initial stage of drying, due to the high moisture content of the clothes and the high humidity in the drum, the humidity-sensitive color-changing particles will change from the initial color to light red due to moisture absorption saturation. As the drying process continues, the humidity in the clothes and the air in the drum gradually decreases, and the humidity-sensitive color-changing particles will also change color due to the decrease in humidity. When entering the drying judgment stage, the image detection device will identify the color of the humidity-sensitive color-changing particles and judge whether the clothes are dried at this time according to the color of the humidity-sensitive color-changing particles. That is, if the image detection device recognizes that the humidity-sensitive color-changing particles change from light red to dark blue, it is determined that the clothes are dry, and then the drying and cooling command can be executed. When the temperature in the drum drops below 60°C, the machine door is unlocked and the program ends; if the image detection device recognizes that the color of the humidity-sensitive color-changing particles is still light red, it is determined that the clothes are not dry and the moisture content is high. Here, if the image detection device recognizes that the color of the humidity-sensitive color-changing particles changes from light red to purple or purple-red, it is determined that the clothes are not dry but the moisture content is low. Furthermore, if the color-changing particles that are sensitive to moisture are identified as light red, purple, or purplish red, the drying process will continue to run, and the dryness judgment will be performed again every N seconds, and the above operation will be repeated until the clothes are determined to be dry. Among them, N is a variable, which can be adjusted and optimized according to the dryness judgment result. For example, when the clothes are relatively damp, it is set to judge the dryness every 5 seconds, and take the results of the last 9 dryness judgments. If a color change is detected, such as from purplish red to purple, and the degree of color change is close to the set range, it is judged and calculated whether to shorten the drying time; when the clothes are close to the drying completion stage, it is set to judge the dryness every 2 seconds, and take the results of the last 9 dryness judgments. If the humidity-sensitive color-changing particles are detected to be dark blue 9 times and the number of times the dark blue is detected accounts for more than 2 / 3, it is determined that the clothes are dry, and then the drying and cooling command is executed.

[0058] In some preferred embodiments, the judgment of drying by the humidity-sensitive color-changing particles can be combined with the judgment of drying by the temperature-sensitive bag, so as to further improve the accuracy of the judgment of drying. The temperature-sensitive bag is fixed in position, and the judgment of the temperature and humidity of the local position of the drying inner drum 1 is more accurate. The humidity-sensitive color-changing particles are located in the humidity-sensitive space 2. When the airflow of the drying inner drum 1 is uniformly circulated by the circulating fan 4, the judgment of the flow humidity of the drying inner drum 1 is more accurate. Therefore, the two judgment results are combined as the basis for the final judgment of drying, which can make the final judgment of drying more accurate and reliable. Specifically, the humidity-sensitive color-changing particles are judged to be dry first, and the flow humidity in the drum is judged. When the color of the humidity-sensitive color-changing particles is identified to be purple or purple-red, the humidity in the drum drops by one stage, and the temperature-sensitive bag is started to judge the drying, and the judgment time interval of the humidity-sensitive color-changing particles and the temperature-sensitive bag is set to be the same. Subsequently, when the humidity-sensitive color-changing particles appear dark blue and the temperature-sensitive bag data reaches a preset value, it is judged that the clothes are completely dried and the drying and cooling command is executed.

[0059] In another practical application scenario, the moisture sensing space 2 is arranged in the glass door of the clothing processing device. For example, the glass door of the clothing processing device can be used as the moisture sensing space 2, that is, a moisture sensing material 3 is placed in the glass door, and an image detection device 4 is arranged below the moisture sensing material 3. The image detection device 4 identifies the change in the color of the moisture sensing material 3. The color presented can represent the humidity in the air and the moisture content of the clothing. Therefore, the moisture content of the clothing, that is, the degree of drying of the clothing, can be judged by identifying the color of the moisture sensing material 3. It can be understood that the glass door described in this embodiment refers to a transparent door installed on the clothing processing device. Since it is bowl-shaped, it can also be called a glass bowl. Of course, in some clothing processing devices, the material of the transparent door can also be plastic, that is, the moisture sensing space 2 is arranged in the plastic door of the clothing processing device.

[0060] In one embodiment, a circulation fan 4 is provided between the drying inner drum 1 and the moisture sensing space 2. The circulation fan 4 is located above the moisture sensing material 3. The circulation fan 4 is used to be turned on and rotate intermittently during the drying process of the clothing processing equipment.

[0061] In this embodiment, the drying inner drum 1 is connected to the humidity sensing space 2, so that air circulation between the drying inner drum 1 and the humidity sensing space 2 can be achieved. In order to ensure the intercommunication and uniformity of humid hot air, a circulating fan 4 is arranged at the junction of the drying inner drum 1 and the humidity sensing space 2, so that the air in the drying inner drum 1 can be pumped into the humidity sensing space 2 where the humidity sensing material 3 is placed through the circulating fan 4, and fully contact with the humidity sensing material 3, thereby achieving effective exchange and uniformity of humidity in the drying inner drum 1, so that the final dryness judgment result is more accurate and more representative.

[0062] In addition, when the clothing processing equipment dries multiple loads or heavy clothes, the wind circulation driven by the rotation of the circulating fan 4 can also extract the hot and humid air inside the load to a certain extent, thereby effectively ensuring the exchange of hot and humid air inside and outside the load, making the drying more uniform and avoiding problems such as over-drying of the outside of the load while the inside is still wet.

[0063] like Figure 3As shown, during drying, the dry hot air is blown obliquely downward from the upper part of the junction between the humidity sensing space 2 and the drying inner drum 1 into the drying inner drum 1, and exchanges moisture with the wet clothes in the drying inner drum 1, becoming humid hot air. Then, the humid hot air is driven into the humidity sensing space 2 by the circulation fan 4, and after fully contacting the humidity sensing material 3, it flows upward along the humidity sensing space 2 and merges with the dry hot air at the air inlet. In this way, the circulation fan 4 can fully exchange the drying airflow of the drying inner drum 1, which can accelerate the heat exchange rate to a certain extent, shorten the drying time, and improve the drying effect. It should also be noted that when the hygroscopic material 3 is hygroscopic color-changing particles, since the hygroscopic color-changing particles are small in size and large in number, and will be piled at the bottom of the hygroscopic space 2, in order to avoid the situation where the top is fully hygroscopic and color-changing, while the bottom is not fully exposed to the humid hot air when exchanging humid and hot air, resulting in inconsistent colors between the top and the bottom, the wind direction of the circulating fan 4 is controlled to blow from top to bottom onto the hygroscopic color-changing particles, and through the gaps between the hygroscopic color-changing particles, the humid and hot air is evenly in contact with each hygroscopic color-changing particle, ensuring that the hygroscopic color-changing particles are evenly hygroscopic and have a uniform color, thereby achieving effective and accurate judgment.

[0064] Specifically, the circulation fan 4 is turned on during the drying process of the clothes processing equipment and rotates intermittently.

[0065] The circulation fan 4 is turned on and rotates intermittently when the drying program reaches the drying judgment stage. The so-called intermittent rotation means that the rotation time does not exceed Xs and the stop time does not exceed Ys, for example, the rotation time does not exceed 10s and the stop time does not exceed 5s. This is because in the drying judgment stage, the image detection device 4 will perform color recognition on the moisture-sensitive material 3 every Ns and judge it to be dry by calculation, so in the drying judgment stage, the circulation fan 4 and the drying inner drum 1 will stop rotating at the same time to ensure the detection accuracy of the image detection device 4. For example, in the drying judgment stage, the circulation fan 4 stops rotating for 1s every Ns to ensure that the objects within the range detected by the image detection device 4 are stationary within this 1s, and are not affected by the operation and wind speed of the drying inner drum 1 to affect the color judgment result, thereby further improving the accuracy of the judgment. When the color of the moisture-sensitive material 3 detected by the image detection device 4 is dark blue, when it is determined that the clothes are dry, the circulation fan 4 can stop running.

[0066] In one embodiment, a filter screen 5 is further provided between the drying inner drum 1 and the humidity sensing space 2 , and the filter screen 5 is located on a side of the humidity sensing material 3 close to the drying inner drum 1 and below the circulation fan 4 .

[0067] In order to ensure that impurities such as clothing lint generated during drying do not enter the humidity sensing space 2, a filter 5 can be placed at the junction of the humidity sensing space 2 and the drying inner drum 1 in this embodiment, so that air circulation can be ensured and impurities such as lint can be prevented from entering the humidity sensing space 2 and affecting the dryness judgment result. Specifically, when the circulation fan 4 and the filter 5 are both arranged between the drying inner drum 1 and the humidity sensing space 2, the filter 5 can be specifically arranged between the humidity sensing space 2 and the circulation fan 4.

[0068] like Figure 4 As shown, an embodiment of the present invention further provides a method for controlling a clothing processing device, and the method includes steps S101 to S102.

[0069] Step S101, during the clothes drying process of the clothes processing equipment, a color image of the moisture-sensitive material 3 is collected by an image detection device;

[0070] Step S102: judging the clothes drying state of the clothes processing device according to the color of the moisture-sensitive substance 3 in the color image.

[0071] In this embodiment, the image detection device 4 detects the color image of the moisture-sensitive material 3 in the drying inner drum 1 to obtain the air humidity level and the degree of dryness of the clothes in the drying inner drum 1, so that the dryness and drying process of the clothes can be effectively and accurately judged, thereby solving the problem of insufficient accuracy of the clothes processing equipment in judging the drying process and improving the drying control effect of the clothes processing equipment. In addition, after the clothes are washed and the washing machine is in an idle state, the moisture-sensitive material 3 can also absorb the moisture in the air of the drying inner drum 1 to keep the inner drum dry and reduce mold and odor.

[0072] In one embodiment, if Figure 5 As shown, the step S102 includes: steps S201 to S202.

[0073] Step S201: when the color of the moisture-sensitive material 3 changes from the initial color to the first preset reference color, it is determined that the drying state of the clothes is not dried;

[0074] Step S202: When the color of the moisture-sensitive material 3 changes from the first preset reference color to the second preset reference color, it is determined that the clothes are in a drying state.

[0075] Since the moisture sensing material 3 described in this embodiment can absorb moisture in the air and change the corresponding color according to the amount of moisture absorbed, that is, different colors represent the humidity in the air, the drying state of the clothes can be judged according to the color change of the moisture sensing material 3. For example, when the moisture sensing material 3 changes from the initial color for the first time, it can represent that the clothes are in the beginning stage of drying, and when the color of the moisture sensing material 3 changes for the second time, it can represent that the clothes are in the end stage of drying.

[0076] In a specific embodiment, when the color of the moisture sensing material 3 changes from the initial color to the first preset reference color, determining that the drying state of the clothes is not dried includes:

[0077] When the color of the moisture sensing material 3 changes from blue to purple or red, it is determined that the clothes are not dried;

[0078] When the color of the moisture-sensitive material 3 changes from the first preset reference color to the second preset reference color, determining that the clothes are in a dried state includes:

[0079] When the color of the moisture sensing material 3 changes from purple or red to blue, it is determined that the clothes are in the drying state as dried.

[0080] In the initial stage of drying, due to the high moisture content of the clothes and the high humidity in the drum, the humidity-sensitive color-changing particles will change from the initial color to light red due to moisture absorption saturation. As the drying process continues, the humidity in the clothes and the air in the drum gradually decreases, and the humidity-sensitive color-changing particles will also change color due to the decrease in humidity. When entering the drying judgment stage, the image detection device will identify the color of the humidity-sensitive color-changing particles and judge whether the clothes are dried at this time according to the color of the humidity-sensitive color-changing particles. That is, if the image detection device recognizes that the humidity-sensitive color-changing particles change from light red to dark blue, it is determined that the clothes are dry, and then the drying and cooling command can be executed. When the temperature in the drum drops below 60°C, the machine door is unlocked and the program ends; if the image detection device recognizes that the color of the humidity-sensitive color-changing particles is still light red, it is determined that the clothes are not dry and the moisture content is high. Here, if the image detection device recognizes that the color of the humidity-sensitive color-changing particles changes from light red to purple or purple-red, it is determined that the clothes are not dry but the moisture content is low. In the initial stage of drying, due to the high moisture content of the clothes and the high humidity in the drum, the humidity-sensitive color-changing particles will change from the initial color to light red due to moisture absorption saturation. As the drying process continues, the humidity in the clothes and the air in the drum gradually decreases, and the humidity-sensitive color-changing particles will also change color due to the decrease in humidity. When entering the drying judgment stage, the image detection device will identify the color of the humidity-sensitive color-changing particles and judge whether the clothes are dried at this time according to the color of the humidity-sensitive color-changing particles. That is, if the image detection device recognizes that the humidity-sensitive color-changing particles change from light red to dark blue, it is determined that the clothes are dry, and then the drying and cooling command can be executed. When the temperature in the drum drops below 60°C, the machine door is unlocked and the program ends; if the image detection device recognizes that the color of the humidity-sensitive color-changing particles is still light red, it is determined that the clothes are not dry and the moisture content is high. Here, if the image detection device recognizes that the color of the humidity-sensitive color-changing particles changes from light red to purple or purple-red, it is determined that the clothes are not dry but the moisture content is low. Furthermore, if the color-changing particles that are sensitive to moisture are identified as light red, purple, or purplish red, the drying process will continue to run, and the dryness judgment will be performed again every N seconds, and the above operation will be repeated until the clothes are determined to be dry. Among them, N is a variable, which can be adjusted and optimized according to the dryness judgment result. For example, when the clothes are relatively damp, it is set to judge the dryness every 5 seconds, and take the results of the last 9 dryness judgments. If a color change is detected, such as from purplish red to purple, and the degree of color change is close to the set range, it is judged and calculated whether to shorten the drying time; when the clothes are close to the drying completion stage, it is set to judge the dryness every 2 seconds, and take the results of the last 9 dryness judgments. If the humidity-sensitive color-changing particles are detected to be dark blue 9 times and the number of times the dark blue is detected accounts for more than 2 / 3, it is determined that the clothes are dry, and then the drying and cooling command is executed.

[0081] Further, such as Figure 6 As shown, the step S201 includes: steps S301 to S302.

[0082] Step S301, collecting a color image of the humidity sensing material 3 once at a first preset time interval, and judging whether the color of the humidity sensing material 3 begins to change from a first preset reference color to a second preset reference color according to the color image;

[0083] Step S302: when it is determined that the color of the hygroscopic substance 3 begins to change from the first preset reference color to the second preset reference color, a color image of the hygroscopic substance 3 is collected once every second preset time interval; wherein the first preset time interval is greater than the second preset time interval.

[0084] In this embodiment, the drying process is regulated according to the color change of the moisture-sensitive material 3 to improve the overall drying efficiency. For example, if the moisture-sensitive color-changing particles are identified as light red, purple, or purple-red, the drying process continues to run, and the dryness is judged again every Ns, and the above operation is repeated until the clothes are judged to be dry. Wherein, N is a variable, which can be adjusted and optimized according to the dryness judgment result. For example, when the clothes are relatively damp, it is set to judge dryness every 5s, and take the results of nearly 9 dryness judgments. If a color change is detected, such as from purple-red to purple, and the degree of color change is close to the set range, it is judged and calculated whether to shorten the drying time; when the clothes are close to the drying completion stage, it is set to judge dryness every 2s, and take the results of nearly 9 dryness judgments. If the moisture-sensitive color-changing particles are detected to be dark blue 9 times, and the number of times the dark blue is detected accounts for more than 2 / 3, it is judged that the clothes are dry, and then the drying and cooling command is executed.

[0085] In one embodiment, if Figure 7 As shown, the step S102 includes: steps S401 to S404.

[0086] Step S401, determining whether the color of the humidity sensing material 3 changes from the initial color to the first preset reference color;

[0087] Step S402: when it is determined that the color of the moisture-sensitive material 3 changes from the initial color to the first preset reference color, the temperature-sensitive bag data is collected; wherein the temperature-sensitive bag data is collected by the temperature-sensitive bag arranged on the drying inner drum 1;

[0088] Step S403, determining whether the color of the humidity sensing material 3 changes from the first preset reference color to the second preset reference color, and determining whether the temperature sensing bag data reaches a preset temperature threshold;

[0089] Step S404: when the color of the moisture sensing material 3 changes from the first preset reference color to the second preset reference color and the temperature sensing bag data reaches the preset temperature threshold, it is determined that the clothes drying state is the dried state.

[0090] This embodiment combines the judgment of dryness by humidity-sensitive color-changing particles with the judgment of dryness by temperature-sensitive bag, so as to further improve the accuracy of the judgment result. The temperature-sensitive bag is fixed in position, and the judgment of the temperature and humidity of the local position of the drying inner drum 1 is more accurate. The humidity-sensitive color-changing particles are located in the humidity-sensitive space 2. When the airflow of the drying inner drum 1 is uniformly circulated with the circulating fan 4, the judgment of the flow humidity of the drying inner drum 1 is more accurate. Therefore, the two judgment results are combined as the basis for the final judgment result, which can make the final judgment result more accurate and reliable. Specifically, the humidity-sensitive color-changing particles are judged to be dry first, and the flow humidity in the drum is judged. When the color of the humidity-sensitive color-changing particles is identified to be purple or purple-red, the humidity in the drum drops by one stage, and the temperature-sensitive bag is started to judge dryness, and the judgment time interval of the humidity-sensitive color-changing particles and the temperature-sensitive bag is set to be the same. Subsequently, when the humidity-sensitive color-changing particles appear dark blue and the temperature-sensitive bag data reaches the preset value, it is judged that the clothes are completely dried and the drying and cooling command is executed.
