Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of clothing processing, and in particular relates to a control method for clothing processing equipment. Background Art
[0002] As people's living standards continue to improve, people have higher and higher demands for the cleaning and care of clothes. Usually, a washing machine is used to clean the clothes to be processed. After cleaning, the clothes cannot be worn directly and need to be dried. At present, people usually use a dryer to quickly dry the clothes. In this way, the washed clothes can be worn after drying, which is convenient and fast. Usually, a clothing care machine uses a single heat source (such as a heating wire or a heat pump system, etc.) to heat and care for the clothes.
[0003] However, the above heating methods all have disadvantages. For example, the heating wire can quickly increase the temperature of the clothes in the inner drum, but the cooling process is very slow; for another example, the heat pump system increases the temperature of the clothes in the inner drum slowly. This will prolong the time for clothing care, which takes a long time and the user experience is poor.
[0004] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention
[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that it takes a long time for existing clothing care machines to complete clothing care, the present invention provides a control method for a clothing processing device on the one hand, the clothing processing device includes a clothing processing drum, and the clothing processing device is equipped with a first heating device and a second heating device capable of increasing the temperature in the clothing processing drum. The control method includes: obtaining the temperature and humidity in the clothing processing drum; and operating the first heating device and / or the second heating device according to the temperature and / or the humidity.
[0006] In a preferred technical solution of the above control method, the clothes processing device includes a first air duct and a second air duct arranged in parallel, and the first heating device and the second heating device are respectively arranged in the first air duct and the second air duct.
[0007] In the preferred technical solution of the above control method, the first heating device is a heating wire, and the step of "operating the first heating device and / or the second heating device according to the temperature and / or the humidity" specifically includes: when the humidity is greater than the first preset humidity, at least turning on the heating wire until the temperature of the clothing processing drum rises to the first preset temperature.
[0008] In the preferred technical solution of the above control method, the second heating device is a heat pump system, and the step of "operating the first heating device and / or the second heating device according to the temperature and / or the humidity" specifically includes: when the humidity is greater than the second preset humidity, turning on the heating wire and / or the heat pump system until the temperature of the clothing processing drum is raised to the second preset temperature; wherein the second preset humidity is lower than the first preset humidity, and the second preset temperature is higher than the first preset temperature.
[0009] In the preferred technical solution of the above control method, after the step of "when the humidity is greater than the second preset humidity, turning on the heating wire until the temperature of the clothing processing drum rises to the second preset temperature", the control method also includes: making the heating wire and / or the heat pump system run for a first preset time in an alternating manner of turning on and off.
[0010] In the preferred technical solution of the above control method, after the step of "making the heating wire run in an alternating on and off manner for a first preset time", the control method includes: only turning on the heat pump system until the humidity reaches a third preset humidity; wherein the third preset humidity is lower than the second preset humidity.
[0011] In the preferred technical solution of the above control method, the clothing processing equipment is equipped with a fan. After the step of "only turning on the heat pump system until the humidity reaches a third preset humidity", the control method also includes: turning off the heating wire, the heat pump system and the fan, and running the clothing processing drum for a second preset time.
[0012] In the preferred technical solution of the above control method, the control method also includes: detecting the temperature of the downstream side of the heating wire; turning off the heating wire when the temperature of the downstream side is higher than a third preset temperature; the third preset temperature is greater than the second preset temperature.
[0013] In a preferred technical solution of the above control method, the control method further includes: obtaining the continuous operation time of the heating wire; and turning off the heating wire when the continuous operation time is greater than a third preset time.
[0014] It can be understood by those skilled in the art that in the technical solution of the present invention, the clothing treatment device includes a clothing treatment drum, and the clothing treatment device is equipped with a first heating device and a second heating device, and the first heating device and the second heating device can increase the temperature in the clothing treatment drum. The control method of the present invention includes obtaining the temperature and humidity in the clothing treatment drum, and operating the first heating device and / or the second heating device according to the temperature and / or humidity, that is, the temperature in the clothing treatment drum can be increased by operating only one of the first heating device or the second heating device, or by operating the first heating device and the second heating device together. The specific operating time, operating mode and operating-related temperature can be determined by referring to factors such as the fabric and type of the clothing to be processed and the needs of the user. In addition, under the premise of ensuring that the first heating device and the second heating device can operate separately and together, the respective positions of the two and the positional relationship between the two can be flexibly set according to the specific application scenario to adapt to different heating needs.
[0015] In the preferred technical solution of the present invention, the clothing processing equipment includes a first air duct and a second air duct arranged in parallel, and the first heating device and the second heating device are respectively arranged in the first air duct and the second air duct. In this way, the first heating device and the second heating device can increase the temperature in the clothing processing drum without interfering with each other.
[0016] Furthermore, the first heating device is a heating wire. Since the power of the heating wire is usually large, it can quickly increase the temperature in the clothing treatment drum. Therefore, when the humidity obtained is large (such as greater than the first preset humidity), at least the heating wire is turned on until the temperature in the clothing treatment drum rises to the first preset temperature. This is because: at this time, it is in the early stage of care, the temperature is low and the humidity is high, so it is necessary to quickly increase the temperature in the clothing treatment drum to dehumidify. At the same time, since the overall humidity is high, the integrity of the clothes can be guaranteed even if the temperature is quickly increased and the humidity is reduced, that is, the clothes to be cared for will not be damaged due to rapid heating and dehumidification. For example, at least the heating wire can be turned on, and the heating wire and the second heating device can also be operated at the same time to raise the temperature in the clothing treatment drum to the first preset temperature.
[0017] Furthermore, the second heating device is a heat pump system. When the acquired humidity is greater than the second preset humidity and less than the first preset humidity, the heating wire and / or the heat pump system is turned on until the temperature in the clothing treatment drum rises to the second preset temperature, the second preset temperature is greater than the first preset temperature, and the second preset humidity is less than the preset humidity, and the clothing is further cared for by adjusting the temperature and humidity in the clothing treatment drum; thereafter, the heating wire and / or the heat pump system is operated for a first preset time in an alternating manner of turning on and off, so as to perform cyclic care for the clothing. Obviously, the on and off time of the heating wire and / or the heat pump system can be determined according to the fabric and type of the clothing to be treated.
[0018] Furthermore, after the circulation care, only the heat pump system is turned on until the acquired humidity reaches a third preset humidity, wherein the third preset humidity is lower than the second preset humidity, that is, after the clothes drying care, the moisture in the air flowing through the heat pump system is removed by the heat pump system, thereby reducing the humidity in the clothes processing drum to the third preset humidity, thereby achieving the purpose of clothes care; thereafter, the heating wire, the heat pump system and the fan are all turned off, and the clothes processing drum is run for the second preset time, so as to shake out the clothes in the clothes processing drum, that is, the clothes are no longer tangled together, so as to improve the user experience.
[0019] Furthermore, the control method further includes detecting the temperature of the downstream side of the heating wire, and turning off the heating wire when the temperature of the downstream side is higher than a third preset temperature, wherein the third preset temperature is greater than the second preset temperature; or the control method further includes obtaining the continuous operation time of the heating wire, and turning off the heating wire when the continuous operation time is greater than the third preset time. Through such a setting, it is ensured that the temperature of the air flowing through the heating wire is not too high, that is, it is ensured that the temperature in the clothes processing drum is not too high, so as to avoid damage to the clothes due to excessive temperature.
[0020] Another aspect of the present invention provides a clothes processing device, the clothes processing device comprising a controller, and the controller is used to execute the control method of the clothes processing device described in any of the above schemes.
[0021] It should be noted that the clothing processing device has all the technical effects of the control method of the aforementioned clothing processing device, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS
[0022] The control method of the clothing treatment device of the present invention is described below with reference to the accompanying drawings and in combination with a clothing care machine. In the accompanying drawings:
[0023] Figure 1 A control method for a clothing care machine according to an embodiment of the present invention is shown in FIG. Figure 1 ;
[0024] Figure 2 A control method for a clothing care machine according to an embodiment of the present invention is shown in FIG. Figure 2 . DETAILED DESCRIPTION
[0025] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although this embodiment is described by taking a clothing care machine as an example, it can also be applied to other clothing processing equipment such as a dryer, a washer-dryer, etc.
[0026] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0027] The clothing care machine mainly includes a housing, an inner drum arranged in the housing, a driving motor for driving the inner drum to rotate, a first heating device, a second heating device, a humidifying device and a fan. During the clothing care process, the driving motor drives the inner drum to rotate, and the fan makes the air in the inner drum circulate between the heating wire and / or the heat pump system and the inner drum, thereby achieving the purpose of clothing care. The humidifying device includes a water inlet pipeline and a nozzle. The nozzle is an atomizing nozzle, which is arranged above the inner drum and is used to increase the humidity in the inner drum.
[0028] The clothing care machine includes a first air duct and a second air duct arranged in parallel, the first heating device is a heating wire, and the second heating device is a heat pump system, wherein the heat pump system includes a condenser and an evaporator, the evaporator is used to reduce the temperature of the air flowing through the evaporator, and the condenser is used to increase the temperature of the air flowing through the condenser. The heating wire and the heat pump system are respectively arranged in the first air duct and the second air duct, the air outlet of the inner drum is connected to the first air duct main pipe, and the air inlet is connected to the second air duct main pipe, and the first air duct and the second air duct are arranged between the first air duct main pipe and the second air duct main pipe. Obviously, the heating wire and the heat pump system can also be arranged in series in the air duct between the air inlet and the air outlet of the inner drum, and those skilled in the art can flexibly select the setting method of the heating wire and the heat pump system according to the specific application scenario, so as to adapt to more specific application occasions.
[0029] It is understandable that the first heating device and the second heating device may also be arranged in other ways, such as the first heating device and the second heating device are both heating wires, etc. Technical personnel in this field can flexibly select the arrangement of the first heating device and the second heating device according to the specific application scenario so as to adapt to more specific application scenarios.
[0030] The clothing care machine is also equipped with a humidity detection component capable of detecting humidity and a temperature detection component capable of detecting temperature. For example, the humidity detection component is a humidity detector and the temperature detection component is a temperature detector, which can be arranged in the inner drum or in the air duct main pipe (close to the air outlet or air inlet of the inner drum). For example, the temperature detection component is a temperature sensor, which is arranged in the second air duct, downstream of the heating wire, etc. The controller can control the operation control method of the clothes dryer of the present invention according to the detection result of the detection component.
[0031] In addition, in the present invention, the heating wire or the heat pump system can be used alone to increase the temperature in the inner cylinder, and the heating wire and the heat pump system can also be used simultaneously to increase the temperature in the inner cylinder.
[0032] The control method of the clothing care machine of the present invention is explained below by taking an example in which both the humidity detector and the temperature detector are arranged in the inner drum and the temperature sensor is arranged in the second air duct.
[0033] Reference Figure 1 , Figure 1 A control method for a clothing care machine according to an embodiment of the present invention is shown in FIG. Figure 1 .like Figure 1 As shown, the control method of the clothing care machine mainly includes the following steps:
[0034] S100: Obtain the temperature and humidity in the inner drum.
[0035] S200: According to the temperature and / or humidity, the heating wire and / or the heat pump system are operated by a controller.
[0036] Through such a setting, the temperature and / or humidity in the inner drum can be set at different stages according to the fabric, type and user needs of the clothes. According to the corresponding temperature and / or humidity, the heating wire and / or heat pump system can be selectively turned on by the controller to increase the temperature in the inner drum. For example, when the clothes are light and thin, the temperature and / or humidity in the inner drum can be set lower.
[0037] Reference Figure 2 , Figure 2 A control method for a clothing care machine according to an embodiment of the present invention is shown in FIG. Figure 2 .like Figure 2As shown, in a preferred embodiment, the control method of "operating the heating wire and / or the heat pump system according to the temperature and / or humidity" may include:
[0038] S21: Obtaining the humidity and / or temperature in the inner cylinder;
[0039] S22: When the humidity is greater than a first preset humidity, at least the heating wire is turned on until the temperature in the inner cylinder rises to a first preset temperature.
[0040] In this embodiment, since the power of the heating wire is relatively large, in step 22, by at least turning on the heating wire, the temperature in the inner drum can be quickly increased, so that the temperature of the clothes can be increased to a first preset temperature, such as 55°C-65°C, as soon as possible. This stage is essentially a preheating care stage, and the main purpose of the preheating care stage is to quickly reduce the humidity in the inner drum. Since the overall temperature is relatively low, rapid dehumidification will not cause damage to the clothes. Obviously, when heating, the temperature in the inner drum can be increased by operating only the heating wire through the controller, or the heating wire and the heat pump system can work together to increase the temperature in the inner drum. Those skilled in the art can flexibly choose according to the specific application scenario, as long as the temperature in the clothing treatment drum can be quickly increased.
[0041] S23: When the humidity is greater than the second preset humidity and less than the first preset humidity, the heating wire and / or the heat pump system are turned on until the temperature in the inner drum rises to the second preset temperature; wherein the second preset humidity is lower than the first preset humidity, and the second preset temperature is higher than the first preset temperature.
[0042] In this embodiment, in order to prevent the humidity in the inner drum from being too low, resulting in poor hand feel (insufficient softness) of the clothes after care, a humidifier can be used to increase the humidity in the inner drum so that the humidity in the inner drum can be maintained between the second preset humidity and the first preset humidity. This stage is essentially a spray care stage. On the one hand, the controller allows the heating wire and / or the heat pump system to freely select the temperature in the inner drum to be raised to the second preset temperature, such as 85°C-95°C, etc., and preferably the heating wire and the heat pump system are operated at the same time. At the same time, due to the assistance of the humidifier, the clothes as a whole are at a reasonable humidity level, that is, the clothes will be kept in a high temperature and reasonable humidity environment for a certain period of time. Through such a setting, the softness of the clothes can be ensured while drying the clothes.
[0043] S24: The heating wire and / or the heat pump system are operated for a first preset time in an alternating manner of turning on and off.
[0044] In this embodiment, in order to better care for the clothes, after the spray care stage, the controller makes the heating wire and / or the heat pump system run for the first preset time in an alternating manner of turning on and off, so this stage is essentially a cyclic heat care stage. Taking the heating wire as the heat source as an example, the heating wire can be controlled to turn on for 3 minutes and stop for 1 minute for 2-5 times (the specific number of times is determined according to the fabric and type of the clothes). In the cyclic heat care process, by adjusting the length of the first preset time, the temperature in the inner drum is controlled within a certain temperature range (such as 70-80°C, etc.), so as to better care for the clothes.
[0045] S25: Only the heat pump system is turned on until the humidity reaches a third preset humidity, wherein the third preset humidity is lower than the second preset humidity.
[0046] In this embodiment, since one of the purposes of clothing care is to dry clothes, the humidity reaching the standard is an indicator that must be completed. At the same time, the humidity at this time is already at a relatively low level, so the rapid heating method may damage the clothes. In view of this, the controller only turns on the heat pump system, and the air in the inner drum flows through the evaporator through the air outlet, the first air duct main pipe, and the second air duct in turn. The moisture in the air condenses on the surface of the evaporator, thereby reducing the humidity in the air, and then reducing the humidity in the inner drum to the third preset humidity that meets the standard. This process is essentially a dehumidification care stage, and the heat source used in the entire process is the heat pump system, so the temperature in the inner drum is maintained within a reasonable temperature range, such as 45-55°C, etc., to better perform clothing care.
[0047] S26: The heating wire, the heat pump system and the fan are all turned off, and the inner drum is operated for a second preset time.
[0048] In this embodiment, after the dehumidification care stage, the temperature and humidity have reached the standard, and the clothes have been basically cared for, but there may be a problem of clothes tangling. At this time, the heating wire, heat pump system and fan can be turned off by the controller, and the inner drum can only rotate for the second preset time. The dried clothes will be scattered as the inner drum rotates, so that the dried clothes can be shaken out, improving the user experience. For example, the inner drum is rotated at the speed of the dehumidification care stage for 5-8 minutes to ensure that the clothes can be fully shaken out.
[0049] In a possible embodiment, the control method of the present invention also includes an overheating protection mechanism for the heating wire. For example, it can be: detecting the temperature of the downstream side of the heating wire, and turning off the heating wire when the temperature of the downstream side is higher than the third preset temperature, wherein the third preset temperature is greater than the second preset temperature. The third preset temperature can more intuitively reflect the temperature of the heating wire. If the temperature is too high (such as 100°C, etc.), the heating wire is turned off. This is to ensure that the temperature of the air flowing through the heating wire is not too high, thereby avoiding damage to the clothes in the inner drum due to excessive temperature. It can also be: obtaining the continuous operation time of the heating wire, and turning off the heating wire when the continuous operation time is greater than the third preset time. Such as 10 minutes, etc. Of course, the overheating protection mechanism may also include the above two methods, such as using the first method in the cyclic thermal care stage and the second method in other stages.
[0050] For example, in a specific embodiment, the working time of the heating wire in the preheating care stage is about 3 minutes, and the temperature of the clothes is increased to the above-mentioned first preset temperature (such as 60°C, etc.); in the spray care stage, the humidifier is turned on for about 30 seconds, and the humidity in the inner drum is between the second preset humidity and the first preset humidity. In this stage, the operation time of the heating wire is about 11 minutes, and the temperature of the clothes is increased to the above-mentioned second preset temperature (such as 90°C, etc.); in the circulating heat care stage, the heating wire is turned on for 1 minute and turned off for 2 minutes to reciprocate twice; in the dehumidification care stage, the heat pump is operated for about 4 minutes, and the humidity in the inner drum is reduced to the above-mentioned third preset humidity that meets the standard. After the temperature and humidity in the inner drum meet the standard, the heating wire, the heat pump system and the fan are turned off, and the inner drum is rotated for 6 minutes at the speed of the initial care stage to fully shake the clothes.
[0051] To sum up, in the preferred technical scheme of the present invention, the heating wire and / or the heat pump system are operated according to the acquired temperature and / or humidity so as to quickly increase the temperature in the inner drum; when the humidity is greater than the first preset humidity, the temperature in the inner drum is increased to the first preset temperature at least by the heating wire, so as to perform preheating care on the clothes in the inner drum; the temperature in the inner drum is increased to the second preset temperature by the heating wire and / or the heat pump system, and the humidity is controlled between the second preset humidity and the first preset humidity with the assistance of the humidifying device, so as to perform spray care on the clothes in the inner drum; after the spray care stage, the clothes in the inner drum are subjected to cyclic heat care by alternating operation of the heating wire and / or the heat pump system; after the cyclic heat care, only the heat pump system is turned on, and the moisture in the air is removed by the evaporator, so that the temperature in the inner drum is reduced within a certain range and the humidity in the inner drum is reduced, so as to perform dehumidification care; on the basis of dehumidification care, the heating wire, the heat pump system and the fan are turned off, and only the inner drum rotates for the second preset time, so as to shake the clothes.
[0052] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
