Abstract
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.

[0047] 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.
[0048] 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:
[0049] The moisture absorption space 2 is communicated with the interior of the drying inner drum 1;
[0050] A hygroscopic material 3 is placed in the hygroscopic space 2 and is used to absorb moisture in the air;
[0051] A weight detection device 4 is disposed in the hygroscopic space 2 and below the hygroscopic material 3, and is used to detect the weight of the hygroscopic material 3;
[0052] The control module is connected to the weight detection device 4, and is used to receive the weight detection result sent by the weight detection device 4, and judge the clothes drying state of the clothes processing device according to the weight detection result.
[0053] In this embodiment, the clothing processing device includes a drying inner drum 1 and a hygroscopic space 2 connected to the drying inner drum 1. The hygroscopic space 2 is provided with a hygroscopic material 3 and a weight detection device 4, such as a weight sensor. This not only improves the circulation and uniformity of the humid hot air, but also allows the hygroscopic material 3 to fully contact with the humid hot air in the drying inner drum 1, thereby achieving the effect of absorbing the humid hot air to increase the weight and desorbing the moisture to reduce the weight. The weight detection device 4 can detect the weight change of the hygroscopic material 3, and thereby determine the air humidity level of the drying inner drum 1 in the clothing processing device, and then determine the dryness of the clothes in the drying inner drum 1.
[0054] In this embodiment, the weight detection device 4 detects the hygroscopic weight of the hygroscopic material 3 in the drying inner drum 1, thereby obtaining 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 in judging the drying of the clothes processing equipment 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 hygroscopic material 3 can also absorb the moisture in the air of the drying inner drum 1, so that the inner drum remains dry and reduces mold and odor.
[0055] In actual application scenarios, the hygroscopic 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 hygroscopic space 2, that is, a hygroscopic substance 3 is placed in the glass door, and a weight detection device 4 is arranged below the hygroscopic substance 3. The weight detection device 4 senses the change in the weight of the hygroscopic substance 3. The increase in its weight 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 determined by calculating the corresponding parameter changes of the weight detection device 4. 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 hygroscopic space 2 is arranged in the plastic door of the clothing processing device.
[0056] like Figure 2 As shown, at the beginning of drying, the higher the moisture content of the clothing load, the higher the humidity in the drying inner drum 1, the higher the moisture absorption rate of the hygroscopic material 3, and the larger the weight value detected by the weight detection device 4. Therefore, the moisture content of the clothing load is positively correlated with the weight detected by the weight detection device 4, as shown in Table 1 below. The moisture content of the clothing load can be judged by the value detected in real time by the weight detection device 4, and the corresponding calculation formula can be obtained, and then the current drying process can be calculated and judged, and the remaining drying time can be adjusted in real time to make the drying more accurate.
[0057] Relative humidity (RH) Hygroscopic material 3 Moisture absorption rate 20% 11% 50% 25% 90% 36%
[0058] Table 1
[0059] As the drying process continues, the humidity of the clothes and the air in the drying inner drum 1 gradually decreases, and the moisture content of the hygroscopic material 3 will also decrease due to the decrease in air humidity. When entering the drying judgment stage, the weight detection device 4 detects the weight of the hygroscopic material 3, and calculates the moisture content of the clothes according to the weight of the hygroscopic material 3, and then determines whether the clothes are dried at this time. The moisture content of clothes refers to the percentage of the water mass of the clothes after drying to the total mass of the clothes. When the moisture content is a positive number, it means that the clothes are in a wet state at this time. The higher the moisture content, the heavier the moisture. When the moisture content is a negative number, it means that the clothes are in a dry state. When the moisture content is between 0% and -2%, the degree of dryness of the clothes is better and most suitable for wearing. Therefore, when it is judged that the moisture content of the clothes load is -2%, the clothes are in a dry state and suitable for wearing. Therefore, when the moisture content of the clothes load is -2%, the weight detected by the weight detection device 4 can be set to x, and this can be used as the threshold. If the weight value detected by the weight detection device 4 is lower than the threshold value x, it is determined that the clothes are dry. At this time, the drying time can be shortened, for example, to 30 minutes, and the drying and cooling command is executed. When the temperature of the drying inner drum 1 drops below 60°C, the machine door is unlocked and the program ends. If the weight value detected by the weight detection device 4 is higher than the threshold value x, it is determined that the clothes are not dry, and the drying will continue. Further, when the weight value detected by the weight detection device 4 is higher than the threshold value x, the dryness is judged again every Ns, and the above operation is 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 moisture content of the clothes is higher than 0%, the dryness is judged every 5s, and the nearly 9 dryness judgment results are taken until the moisture content of the clothes is detected to be lower than 0%, and then the dryness is judged every 2s, and the nearly 9 dryness judgment results are taken. If the value of the moisture content of the clothes detected in 9 times is lower than -2%, the proportion exceeds 2 / 3, it is determined that the clothes are dry. At this time, the drying time can be shortened, for example, to 30 minutes, and the drying and cooling command is executed.
[0060] In some optional embodiments, the weight sensing dryness judgment can also be combined with the temperature sensing bag dryness judgment to further improve the accuracy of the dryness judgment result. The temperature sensing 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 weight detection device 4 is located in the moisture absorption space 2. When the airflow of the drying inner drum 1 is uniformly circulated with the circulating fan 5, the judgment of the flow humidity of the drying inner drum 1 is more accurate. Therefore, the two dryness judgment results are combined as the basis for the final dryness judgment result, which can make the final dryness judgment result more accurate and reliable. Specifically, the weight sensing dryness judgment is first performed to judge the flow humidity of the drying inner drum 1. When the weight detection device 4 detects that the weight value is y and the moisture content of the clothing load corresponds to -10%, the air humidity in the drying inner drum 1 drops by one stage, and the temperature sensing bag dryness judgment is started, and the dryness judgment time interval of the weight sensing dryness judgment and the temperature sensing bag dryness judgment is set to be the same. Subsequently, when the weight value detected by the weight detection device 4 is lower than the threshold value x, that is, the moisture content of the clothing is -2%, and the temperature sensing bag data reaches the preset value, it is determined that the clothing is completely dried, and then the drying and cooling command is executed.
[0061] In one embodiment, a circulation fan 5 is provided between the drying inner drum 1 and the moisture absorbing space 2 , and the circulation fan 5 is located above the moisture absorbing material 3 .
[0062] In this embodiment, the drying inner drum 1 is connected to the hygroscopic space 2, so that air circulation between the drying inner drum 1 and the hygroscopic space 2 can be achieved. In order to ensure the intercommunication and uniformity of humid hot air, a circulating fan 5 is arranged at the junction of the drying inner drum 1 and the hygroscopic space 2, so that the air in the drying inner drum 1 can be pumped into the hygroscopic space 2 where the hygroscopic material 3 is placed through the circulating fan 5, and fully contact with the hygroscopic 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 representative.
[0063] In addition, when the clothing processing equipment dries multiple loads or heavy clothes, the wind circulation driven by the rotation of the circulating fan 5 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.
[0064] like Figure 3 As shown, during drying, the dry hot air is blown obliquely downward from the upper part of the junction between the moisture absorption 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, and then the humid hot air is driven into the moisture absorption space 2 by the circulation fan 5, and after fully contacting with the hygroscopic material 3, it flows upward along the moisture absorption space 2 and merges with the dry hot air at the air inlet. In this way, the circulation fan 5 can fully exchange the drying airflow of the drying inner drum 1, to a certain extent, accelerate the heat exchange rate, shorten the drying time, and improve the drying effect.
[0065] Specifically, the circulation fan 5 is turned on during the drying process of the clothes processing equipment and rotates intermittently.
[0066] The circulation fan 5 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 weight detection device 4 will perform a weight detection on the hygroscopic material 3 every Ns and judge it to be dry through calculation. Therefore, in the drying judgment stage, the circulation fan 5 and the drying inner drum 1 will stop rotating at the same time to ensure the detection accuracy of the weight detection device 4. For example, in the drying judgment stage, the circulation fan 5 stops rotating for 1s every Ns to ensure that the objects within the range detected by the weight 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 weight sensing, thereby further improving the accuracy of the dry judgment. When the weight of the hygroscopic material 3 detected by the weight detection device 4 is less than -2% of the moisture content of the clothes after calculation, the circulation fan 5 can stop running when it is determined that the clothes are dry.
[0067] In one embodiment, a filter screen 6 is further provided between the drying inner drum 1 and the moisture absorption space 2 , and the filter screen 6 is located on a side of the moisture absorption material 3 close to the drying inner drum 1 and below the circulation fan 5 .
[0068] In order to ensure that impurities such as clothing lint generated during drying do not enter the moisture absorption space 2, a filter 6 can be placed at the junction of the moisture absorption 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 moisture absorption space 2 and affecting the dryness judgment result. Specifically, when the circulation fan 5 and the filter 6 are both arranged between the drying inner drum 1 and the moisture absorption space 2, the filter 6 can be specifically arranged between the moisture absorption space 2 and the circulation fan 5.
[0069] In one embodiment, the hygroscopic material 3 includes any one or more of silicon dioxide and water-absorbing resin.
[0070] In this embodiment, the composition of the hygroscopic material 3 can be silica gel, the main component of which is silicon dioxide, and silicon dioxide is a highly active adsorption material, which is in the shape of a rectangular transparent fine mesh and has a strong adsorption effect on water vapor in the air. In a high humidity environment, the hygroscopic material 3 will absorb the surrounding moisture, increasing its own weight. Its moisture absorption rate is usually between 30% and 40%. At the same time, the hygroscopic material 3 absorbs water vapor or other organic substances in the medium during use, and its adsorption capacity decreases. The moisture can be removed by thermal desorption for reuse. That is to say, after the clothes are washed, the humidity of the drying inner drum 1 is high, and the hygroscopic material 3 will absorb the moisture of the drying inner drum 1, thereby increasing the weight. As the drying process proceeds, the high temperature will evaporate the moisture in the hygroscopic material 3, causing it to lose moisture, thereby reducing the weight and restoring its hygroscopic capacity. Of course, in practical applications, other substances with hygroscopic properties such as absorbent resins can also be used as the hygroscopic material 3.
[0071] 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.
[0072] Step S101, during the clothes drying process of the clothes processing device, the weight of the hygroscopic material 3 is detected by the weight detection device 4 to obtain a weight detection result;
[0073] Step S102: determining the clothes drying state of the clothes processing device according to the weight detection result.
[0074] In this embodiment, the weight detection device 4 detects the hygroscopic weight of the hygroscopic material 3 in the drying inner drum 1, thereby obtaining 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 in judging the drying of the clothes processing equipment 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 hygroscopic material 3 can also absorb the moisture in the air of the drying inner drum 1, so that the inner drum remains dry and reduces mold and odor.
[0075] In one embodiment, if Figure 5 As shown, the step S102 includes: steps S201 to S202.
[0076] Step S201, obtaining the moisture content of the clothes according to the weight detection result;
[0077] Step S202: determining whether the clothes are dried according to the moisture content of the clothes.
[0078] At the beginning of drying, the higher the moisture content of the clothing load, the higher the humidity in the drying inner drum 1, the higher the moisture absorption rate of the hygroscopic material 3, and the larger the weight value detected by the weight detection device 4. Therefore, the moisture content of the clothing load is positively correlated with the weight detected by the weight detection device 4. The moisture content of the clothing load can be judged by the value detected in real time by the weight detection device 4, and the corresponding calculation formula can be obtained, and then the current drying process can be calculated and judged, and the remaining drying time can be adjusted in real time to make drying more accurate.
[0079] As the drying process continues, the humidity of the clothes and the air in the drying inner drum 1 gradually decreases, and the moisture content of the hygroscopic material 3 will also decrease due to the decrease in air humidity. When entering the drying dryness judgment stage, the weight detection device 4 detects the weight of the hygroscopic material 3, and calculates the moisture content of the clothes based on the weight of the hygroscopic material 3, and then determines whether the clothes are dry at this time.
[0080] Specifically, Figure 6 As shown, the step S202 includes: steps S301 to S302.
[0081] Step S301: when the moisture content of the clothes is a positive value, it is determined that the clothes are not dried;
[0082] Step S302: When the moisture content of the clothes is a negative value, it is determined that the clothes are dried.
[0083] The moisture content of clothes refers to the percentage of the moisture mass of clothes after drying to the total mass of clothes. When the moisture content is a positive number, it means that the clothes are in a damp state. The higher the moisture content, the more damp it is. When the moisture content is a negative number, it means that the clothes are in a dry state. When the moisture content is between 0% and -2%, the clothes are dry and most suitable for wearing. Therefore, when it is judged that the moisture content of the clothes load is -2%, the clothes are in a dry state and suitable for wearing.
[0084] In one embodiment, if Figure 7 As shown, the step S102 also includes: steps S401 to S403.
[0085] Step S401, determining whether the weight detection result is lower than a first preset weight threshold;
[0086] Step S402: if the weight detection result is not lower than the first preset weight threshold, the clothes drying state is determined to be an undried state;
[0087] Step S403: If the weight detection result is lower than the first preset weight threshold, the clothes drying state is determined to be a dried state.
[0088] In this embodiment, when the moisture content is a positive number, it means that the clothes are in a wet state at this time. The higher the moisture content, the heavier the moisture level. When the moisture content is a negative number, it means that the clothes are in a dry state. Therefore, a weight threshold can be set according to the moisture content of the clothes load. When the weight detection result detected by the weight detection device 4 reaches the weight threshold, it is considered that the moisture content of the corresponding clothes load is in a dry state at this time. For example, when the moisture content of the clothes load is -2%, the weight detected by the weight detection device 4 can be set to x, and this can be used as the threshold. If the weight value detected by the weight detection device 4 is lower than the threshold x, it is determined that the clothes are dry. At this time, the drying time can be shortened, for example, to 30 minutes, and the drying and cooling command is executed. When the temperature of the drying inner drum 1 drops below 60°C, the machine door is unlocked and the program ends. If the weight value detected by the weight detection device 4 is higher than the threshold x, it is determined that the clothes are not dry, and the drying will continue.
[0089] Furthermore, when the weight value detected by the weight detection device 4 is higher than the threshold value x, 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 moisture content of the clothes is higher than 0%, the dryness is judged every 5s, and the results of the last 9 dryness judgments are taken, until the moisture content of the clothes is detected to be lower than 0%, the dryness is judged every 2s, and the results of the last 9 dryness judgments are taken. If the proportion of the values of the moisture content of the clothes detected to be lower than -2% in the 9 times exceeds 2 / 3, the clothes are judged to be dry. At this time, the drying time can be shortened, for example, to 30 minutes, and the drying and cooling command is executed.
[0090] Further, in one embodiment, if Figure 8 As shown, the step S102 also includes: steps S501 to S504.
[0091] Step S501, determining whether the weight detection result reaches a second preset weight threshold; wherein the second preset weight threshold is greater than the first preset weight threshold;
[0092] Step S502: when it is determined that the weight detection result reaches a second preset weight threshold, collecting temperature sensing bag data; wherein the temperature sensing bag data is collected by a temperature sensing bag arranged on the drying inner drum 1;
[0093] Step S503, determining whether the weight detection result is lower than a first preset weight threshold, and determining whether the temperature sensing package data reaches a preset temperature threshold;
[0094] Step S504: when the weight detection result is lower than the first preset weight threshold and the temperature sensing bag data reaches the preset temperature threshold, it is determined that the clothes drying state is the dried state.
[0095] This embodiment combines weight sensing dryness judgment with temperature sensing bag dryness judgment to further improve the accuracy of dryness judgment result. The temperature sensing 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 weight detection device 4 is located in the moisture absorption space 2. When the airflow of the drying inner drum 1 is uniformly circulated with the circulating fan 5, the judgment of the flow humidity of the drying inner drum 1 is more accurate. Therefore, the two dryness judgment results are combined as the basis for the final dryness judgment result, which can make the final dryness judgment result more accurate and reliable. Specifically, firstly, weight sensing dryness judgment is performed to judge the flow humidity of the drying inner drum 1. When the weight detection device 4 detects that the weight value is y and the moisture content of the clothes load corresponds to -10%, the air humidity in the drying inner drum 1 drops by one stage, and the temperature sensing bag dryness judgment is started, and the dryness judgment time interval of the weight sensing dryness judgment and the temperature sensing bag dryness judgment is set to be the same. Subsequently, when the weight value detected by the weight detection device 4 is lower than the threshold value x, that is, the moisture content of the clothes is -2%, and the temperature sensing bag data reaches the preset value, it is determined that the clothes are completely dried, and then the drying and cooling command is executed.
[0096] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments.
