Description

Technical Field

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

[0002] With the development and progress of science and technology, clothing processing equipment can meet more and more clothing processing needs of people, including drying of clothes.

[0003] When the clothes processing device is drying clothes, some special clothes need to be taken out for ironing and wrinkle removal before they are completely dried. After the user takes out the clothes from the clothes processing device, he needs to take them to a separate ironing device for ironing and wrinkle removal, which is complicated and inconvenient to use. In order to solve the above problems, a clothes processing device is provided in the prior art, and the clothes processing device is connected to a care device, but the clothes processing device cannot ensure the effective ironing of the care device while ensuring the drying effect of the clothes.

[0004] Accordingly, the art requires a new clothing processing device and a control method thereof to solve the above problems. Summary of the invention

[0005] The present invention aims to solve the above technical problem, that is, to solve the problem that the clothing processing equipment in the prior art cannot ensure both effective ironing and drying effect of the clothing. In a first aspect, the present invention provides a clothing processing device, comprising: a drying duct, a condensing device and a heating device are provided in the drying duct, and a circulating duct is formed between the drying duct and a processing drum of the clothing processing device; an exhaust port, the exhaust port is connected to the circulating duct; an on-off valve, the on-off valve is used to open and close the exhaust port; a humidity sensor, the humidity sensor is used to detect the moisture content value in the processing drum or the drying duct; a care device, the inlet of the care device is connected to the exhaust port.

[0006] In the case of adopting the above technical solution, the opening and closing of the exhaust port is controlled by controlling the opening and closing of the on-off valve; when the clothing processing equipment dries clothes, the humid gas in the processing drum enters the drying duct and is processed by the condensing device and the heating device, wherein the condensation and dehumidification of the air by the condensing device can gradually reduce the moisture content; in the later stage of drying, some special clothes need to be taken out and ironed and wrinkle-removed before they are completely dried. According to the moisture content value detected by the humidity sensor, when the moisture content value in the processing drum or the drying duct reaches the set value, the on-off valve is controlled to open, and the gas with a certain temperature and humidity in the processing drum or the drying duct is discharged into the care device, and the processing drum or The gas discharged from the drying duct is directly used to care for and iron the clothes that need to be ironed and wrinkle-removed. Since the humidity of the gas at this time is more conducive to ironing, the ironing effect can be improved; after the humid and hot gas in the care barrel or the drying duct is discharged through the exhaust port, the drying efficiency of the clothes is improved and the drying and cooling time is shortened; in addition, the setting of the on-off valve avoids the exhaust port from being kept open all the time. In the early stage of clothes drying, when the humidity of the gas in the circulating duct is high, the gas is continuously discharged from the exhaust port to the external environment. The surrounding environment of the clothing processing equipment will become very hot and humid as the gas is continuously discharged, and even water mist will be generated, which not only reduces the drying efficiency, but also affects the user experience. Therefore, while this solution effectively utilizes the discharged humid and hot gas to iron and care for clothes, it also improves the drying efficiency of the clothing processing equipment and shortens the drying and cooling time.

[0007] In a specific embodiment of the above-mentioned clothes processing device, a plug is connected to the inlet, and the plug is detachably connected to the exhaust port.

[0008] When the above technical solution is adopted, when the clothes need to be ironed and cared for, the care device is connected to the exhaust port through a plug to effectively utilize the exhausted hot and humid gas. When the clothes do not need to be ironed and cared for, the hot and humid gas can be directly discharged into the external environment through the exhaust port.

[0009] In a specific embodiment of the above-mentioned clothes processing device, the clothes processing device further includes a first position detection structure, and the first position detection structure is configured to send a connection signal when the plug is connected to the exhaust port.

[0010] When the above technical solution is adopted, whether the plug is connected to the exhaust port can be detected by the first position detection structure, and a connection signal is sent when the plug is connected to the exhaust port.

[0011] In a specific embodiment of the above-mentioned clothing processing equipment, the condensing device and the heating device are arranged in sequence from the air inlet end to the air outlet end of the drying air duct, and the exhaust port is arranged on the drying air duct and located downstream of the heating device.

[0012] When the above technical solution is adopted, since the gas used by the care device during ironing needs to have a certain humidity and temperature, the gas in the circulating air duct is dehumidified by the condensing device and heated by the heating device before being discharged from the exhaust port, which is more in line with the use requirements of the care device. Therefore, the exhaust port is arranged downstream of the heating device on the drying air duct, so that the exhaust port is close to the heating device, which helps to improve the ironing care effect.

[0013] In a second aspect, the present invention further provides a control method for a clothing processing device, the control method comprising: obtaining a moisture content value detected by the humidity sensor when a drying program is running; and controlling the opening and closing of the on-off valve based on the moisture content value.

[0014] In a specific implementation of the control method of the above-mentioned clothing processing equipment, the step of "controlling the opening and closing of the solenoid valve based on the moisture content value" further includes: when the moisture content value is greater than the second preset value, controlling the on-off valve to close; when the moisture content value is greater than or equal to the first preset value and less than or equal to the second preset value, controlling the on-off valve to open; when the moisture content value is less than the first preset value, controlling the on-off valve to close.

[0015] When the above technical solution is adopted, the present invention controls the on-off valve to open to discharge hot and humid gas when the moisture content value reaches a certain range, thereby improving the drying efficiency and shortening the drying time. When the moisture content value drops below the first preset value, the on-off valve is controlled to close.

[0016] In a specific implementation of the control method for the above-mentioned clothing processing equipment, a plug is connected to the inlet, and the plug is detachably connected to the exhaust port. The clothing processing equipment also includes a first position detection structure, and the first position detection structure is configured to send a connection signal when the plug is connected to the exhaust port; the step of "controlling the on-off valve to open when the moisture content value is greater than or equal to the first preset value and less than or equal to the second preset value" further includes: sending a reminder message when the moisture content value is greater than or equal to the first preset value and less than or equal to the second preset value; after receiving the connection signal, controlling the on-off valve to open.

[0017] When the above technical solution is adopted, when the moisture content value reaches a certain range, a reminder message is sent to inform the user that the ironing care operation can be performed. The user decides whether to perform the ironing care according to the needs. If necessary, the plug is inserted into the exhaust port. The first position detection structure detects that the plug is connected to the exhaust port and sends a connection signal. After the controller receives the connection signal, it controls the on-off valve to open, and the humid hot air is discharged into the care device for ironing care.

[0018] In a specific implementation of the control method for the above-mentioned clothing processing device, after the step of "sending a reminder message", the control method for the clothing processing device further includes: after the connection signal is not received within a preset time, controlling the on-off valve to open.

[0019] In a specific implementation of the control method for the above-mentioned clothing processing equipment, the clothing processing equipment also includes a second position detection structure, and the second position detection structure is configured to send a door closing signal when the door body of the clothing processing equipment is closed, and send a door opening signal when the door body is opened; at the same time or after the step of "after receiving the connection signal, controlling the on-off valve to open", the control method of the clothing processing equipment also includes: controlling the door lock of the clothing processing equipment to unlock, controlling the drying program in the drying stage to pause; after receiving the door opening signal, if the door closing signal is received, controlling the door lock to lock, and controlling the drying program to continue running.

[0020] When adopting the above technical solution, after receiving the connection signal, the on-off valve is controlled to open, and the door lock needs to be controlled to unlock and pause the drying program, waiting for the user to take out the clothes that need to be ironed and wrinkled in the processing drum, and close the door lock after taking them out. The controller locks the door lock and controls the drying program to continue running, ensuring the user's safety.

[0021] In a specific implementation of the control method of the above-mentioned clothing processing equipment, at the same time or after the step of "when the moisture content value is less than the first preset value, controlling the on-off valve to be closed", the control method of the clothing processing equipment also includes: controlling the drying program to end, controlling the door lock of the clothing processing equipment to be unlocked; and / or the step of "when the moisture content value is greater than the second preset value, controlling the on-off valve to be closed; when the moisture content value is greater than or equal to the first preset value and less than or equal to the second preset value, controlling the on-off valve to be opened; when the moisture content value is less than the first preset value, controlling the on-off valve to be closed" further includes: when the moisture content value is greater than 11%, controlling the on-off valve to be closed; when the moisture content value is greater than or equal to 3% and less than or equal to 11%, controlling the on-off valve to be opened; when the moisture content value is less than 3%, controlling the on-off valve to be closed.

[0033] In addition, it should be noted that in the description of the present invention, although the various steps of the control method of the present invention are described in this application in a specific order, these orders are not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in a different order.

[0034] Based on the problem pointed out in the background art that the clothes processing equipment in the prior art cannot ensure both effective ironing and drying effect of clothes, the present invention provides a clothes processing equipment and a control method thereof.

[0035] See first Figure 1 , which shows the overall structure of the laundry processing device of the present invention. Figure 1 As shown, the clothing processing device of the present invention comprises: a drying air duct 1, in which a condensing device 11 and a heating device 12 are arranged, and a circulating air duct is formed between the drying air duct 1 and the processing drum of the clothing processing device; an exhaust port 2, which is connected to the circulating air duct; an on-off valve 3, which is used to open and close the exhaust port 2; a humidity sensor, which is used to detect the humidity in the processing drum or the drying air duct 1; a care device 4, the inlet of the care device 4 is connected to the exhaust port 2. The clothing processing device can be a washing machine, a dryer, a washing and drying machine, a dryer, etc. that can dry clothes, and no specific limitation is made here. The hot and humid gas in the processing drum enters the drying air duct 1, passes through the condensing device 11 and the heating device 12, and the condensing device 11 condenses the water vapor in the gas to achieve the purpose of dehumidification. The heating device 12 is used to heat the dehumidified gas, and the dehumidified and heated gas returns to the processing drum to continue drying the clothes; the moisture content value of the gas in the circulating air duct is detected by the humidity sensor.

[0036] When the humidity of the gas in the circulating air duct is high, the on-off valve 3 can be controlled to be closed, and the condensing device 11 can be used to condense and dehumidify the gas, which can improve the dehumidification efficiency of the gas and thus ensure the drying effect. When the humidity of the gas in the circulating air duct is low, the on-off valve 3 is controlled to be opened so that the exhaust port 2 is opened, and the hot and humid gas in the circulating air duct can be discharged to the care device 4 through the exhaust port 2. The applicant has found through research that when the gas is within the preset humidity range in the late stage of drying, the ironing effect of the care device 4 can be improved, and the drying effect of the clothes can be ensured because the moisture in the circulating air duct is discharged. In addition, since the circulating air duct is sealed, when the moisture content value is low, that is, the clothing processing equipment is in the late stage of drying, the dehumidification effect of the condensing device 11 is limited. Therefore, the on-off valve 3 is controlled to be opened so that the moisture is discharged to the outside of the circulating air duct, which can ensure the drying effect in the late stage of drying. In summary, the clothing processing equipment of the present invention can not only improve the ironing effect of the care device 4, but also ensure the drying effect of the clothing processing equipment.

[0037] Among them, when the moisture content value reaches the set range, the on-off valve 3 is controlled to open, and the gas with a certain temperature and humidity in the circulating air duct is discharged, thereby improving the drying efficiency of the clothes, accelerating the reduction rate of the gas temperature in the circulating air duct, shortening the drying and cooling time, and the humid and hot gas is discharged into the care device 4, and the care device 4 uses the humid and hot gas to directly care for and iron the clothes that need to be ironed and wrinkle-removed.

[0038] When the moisture content value reaches the set range, the on-off valve 3 is controlled to open. Specifically, when the moisture content value is greater than or equal to 3% and less than or equal to 11%, the drying stage enters the late drying stage with low moisture content. At this time, the drying efficiency is reduced, and the gas temperature in the circulating air duct decreases slowly. Since the drying stage can only be ended when the gas temperature and humidity in the circulating air duct drop to a certain set range, the heat and water vapor in the circulating air duct need to be quickly discharged through the exhaust port 2 in the late drying stage to shorten the drying and cooling time and improve the drying efficiency. Compared with the exhaust port 2 being open during the entire drying stage, the humidity of the clothes in the early stage of drying is high, and the humidity and temperature of the gas in the circulating air duct are relatively high. The exhaust port 2 is always kept open, and the gas is continuously discharged from the exhaust port 2 to the external environment. The surrounding environment of the clothing processing equipment will become very hot and humid as the gas is continuously discharged, and even water mist may be generated, affecting the user experience. In addition, in the early stage of drying, there is no need to cool the gas in the circulating air duct, and the moisture of the clothes needs to be evaporated by high-temperature gas. However, the gas discharge not only discharges moisture but also lowers the temperature in the circulating air duct, resulting in reduced drying efficiency.

[0039] Specifically, the on-off valve 3 can be a pneumatic valve, a hydraulic valve, an electric valve, etc., as long as it can be controlled to open and close by a controller. Preferably, the on-off valve 3 is an electromagnetic valve. Regarding the position of the on-off valve 3, the on-off valve 3 can be set in the exhaust port 2 or at both ends of the exhaust port 2, as long as the exhaust port 2 can be controlled to open and close. Those skilled in the art can make adjustments as needed, all within the protection scope of the present invention.

[0040] Regarding the position of the exhaust port 2, the condensing device 11 and the heating device 12 are sequentially arranged in the direction from the air inlet end to the air outlet end of the drying air duct 1, and the exhaust port 2 is arranged on the drying air duct 1 and is located downstream of the heating device 12; since the gas used by the care device 4 during ironing needs to have a certain humidity and temperature, and the gas in the circulating air duct is discharged from the exhaust port 2 after being dehumidified by the condensing device 11 and heated by the heating device 12, it is more in line with the use requirements of the care device 4, so the exhaust port 2 is arranged downstream of the heating device 12 on the drying air duct 1, which helps to improve the effect of ironing care. However, this is not restrictive, and those skilled in the art can also make adjustments as needed.

[0041] Regarding the position of the humidity sensor, the humidity sensor is arranged in the circulating air duct. Specifically, the humidity sensor can be arranged in the drying air duct or in the processing barrel, as long as the moisture content value in the circulating air duct can be detected.

[0042] Preferably, the clothing processing device also includes a heat pump system, the condensing device 11 is an evaporator of the heat pump system, and the heating device 12 is a condenser of the heat pump system. Of course, this is not restrictive. As long as the condensing device 11 can realize condensation and dehumidification of the air, and the heating device 12 can realize heating of the air, it does not deviate from the principle of the present invention and is within the protection scope of the present invention. Possibly, a fan is also provided in the drying duct 1. The fan drives the gas of the treatment drum to enter the drying duct 1 from the air inlet end of the drying duct 1, and passes through the condensing device 11 and the heating device 12 in turn. The gas is cooled and dehumidified by the condensing device 11, heated by the heating device 12, and then returns to the treatment drum from the air outlet end to dry the clothes.

[0043] Continue reading Figure 1 A plug 41 is connected to the inlet of the care device 4, and the plug 41 is detachably connected to the exhaust port 2. When the clothes need to be ironed and cared for, the care device 4 is connected to the exhaust port 2 through the plug 41 to effectively utilize the exhausted hot and humid gas. When the clothes do not need to be ironed and cared for, the hot and humid gas can be directly discharged to the external environment through the exhaust port 2. Specifically, the plug 41 is connected to the care device 4 through a hose, which is convenient for users to operate and use.

[0044] Continue reading Figure 1 The clothing processing device also includes a first position detection structure, and the first position detection structure is configured to send a connection signal when the plug 41 is connected to the exhaust port 2. There are many specific settings for the first position detection structure. For example, the first position detection structure includes a first signal switch and a first signal contact. The first signal switch is provided on the plug / exhaust port, and the first signal contact is provided on the exhaust port / plug. When the plug is connected to the exhaust port, the first signal switch contacts the first signal contact, thereby sending a signal, which is recorded as a connection signal. Of course, the above settings are only exemplary. As long as the first position detection structure can send a signal when the plug is connected to the exhaust port, the specific settings of the first position detection structure can be adjusted. These adjustments do not deviate from the principles of the present invention and are within the protection scope of the present invention.

[0045] Participate below Figure 1 and Figure 2 , Figure 2This is a diagram of the use state of the clothing treatment device of the present invention. The clothing treatment device also includes a wrinkle removal platform. When the user irons and cares for the clothing, the user places the clothing on the wrinkle removal platform and operates the care device 4 to perform the ironing and care operation on the clothing. There is no need to take the clothing to a separate ironing device, which simplifies the operation and is more convenient for the user.

[0046] See below Figure 3 , which shows the main steps of the control method of the clothes processing device of the present invention, which specifically includes the following steps:

[0047] Step S100: When the drying program is running, the moisture content value detected by the humidity sensor is obtained.

[0048] Step S101: Based on the water content value, control the opening and closing of the on-off valve.

[0049] The opening and closing of the on-off valve 3 is controlled by the controller of the clothing processing device. By controlling the opening and closing of the on-off valve 3, the opening and closing of the exhaust port 2 is controlled. When the exhaust port 2 is closed, the circulating air duct is sealed. When the humidity is high, the condensation and dehumidification of the condensation device 11 are performed to achieve a better drying effect. When the exhaust port 2 is opened, the hot and humid gas in the circulating air duct can be discharged through the exhaust port 2, so that when the humidity is relatively low, it is conducive to steam ironing and the drying effect is better. By controlling the opening and closing of the on-off valve 3, the drying effect of the clothing processing device is fully improved.

[0050] See below Figure 4 , which shows the detailed step flow of the first embodiment of the control method of the laundry processing device of the present invention, specifically comprising the following steps:

[0051] Step S200: when the drying program is running, the moisture content value detected by the humidity sensor is obtained.

[0052] Step S201: When the water content value is greater than a second preset value, the on-off valve is controlled to be closed.

[0053] Step S202: When the water content value is greater than or equal to the first preset value and less than or equal to the second preset value, the on-off valve is controlled to open.

[0054] Step S203: When the water content value is less than the first preset value, the on-off valve is controlled to be closed.

[0055] When the moisture content value is greater than the second preset value, the air humidity is high at this time. By controlling the on-off valve 3 to be closed, the condensation device 11 is used to condense and dehumidify the air, which can improve the dehumidification efficiency and thus ensure the drying effect. When the moisture content value is greater than or equal to the first preset value and less than or equal to the second preset value, when the humidity is low, the on-off valve 3 is controlled to be opened, so that the exhaust port 2 is opened, and the hot and humid gas in the circulating air duct can be discharged to the care device 4 through the exhaust port 2. The applicant has found through research that the ironing effect of the care device 4 can be improved in the non-high humidity range in the late drying period, and the drying effect can also be ensured because the moisture in the circulating air duct is discharged. In addition, since the circulating air duct is sealed, when the moisture content value is greater than or equal to the first preset value and less than or equal to the second preset value, the clothing processing equipment is in the late drying period. At this stage, the humidity in the drying air duct is low, resulting in limited dehumidification effect of the condensation device 11. Therefore, the on-off valve 3 is controlled to be opened so that the moisture is discharged to the outside of the circulating air duct, which can ensure the drying effect in the late drying period. In summary, the control method of the clothing processing device of the present invention can not only improve the ironing effect of the care device 4, but also ensure the drying effect of the clothing processing device.

[0056] It should be noted that when the drying program starts, the on-off valve 3 is in a closed state. When the moisture content is greater than the second preset value, the on-off valve 3 is kept closed. As the moisture content drops to a value greater than or equal to the first preset value and less than or equal to the second preset value, the on-off valve 3 is controlled to open, and the humid and hot gas in the circulating air duct is discharged through the exhaust port 2. Under the combined effect of the clothing processing device drying the clothing and the exhaust port 2 being open, the moisture content decreases faster. When the moisture content drops to less than the first preset value, the on-off valve 3 is controlled to close to complete the drying of the clothing. When the plug 41 is not inserted into the exhaust port 2, the exhaust port 2 can be directly connected to the external environment. When the plug 41 is inserted into the exhaust port 2, the exhaust port 2 is connected to the care device 4 to utilize the humid and hot gas for ironing and care of the clothing. Exemplarily, the first preset value can be set to 3%, and the second preset value can be set to 11%. When the moisture content of the gas in the circulating air duct is within the range of greater than or equal to 3% and less than or equal to 11%, the drying efficiency is reduced, and the dehumidification and cooling rates are both reduced. At this time, the on-off valve 3 is controlled to open to discharge the hot and humid air, which can effectively increase the dehumidification and cooling rates and shorten the drying stage time.

[0057] Last read Figure 5 , which shows a detailed step flow of a second embodiment of the control method of the laundry processing device of the present invention, specifically comprising the following steps:

[0058] Step S300: when the drying program is running, the moisture content value detected by the humidity sensor is obtained.

[0059] Step S301: When the water content value is greater than a second preset value, the on-off valve is controlled to be closed.

[0060] Step S302: When the moisture content value is greater than or equal to the first preset value and less than or equal to the second preset value, a reminder message is sent.

[0061] Step S303: Determine whether a connection signal is received within a preset time; if yes, proceed to step S305; if not, proceed to step S304.

[0062] Step S304: Control the on-off valve to open.

[0063] Step S305: controlling the on-off valve to open, controlling the door lock of the clothes processing device to unlock, and controlling the drying program in the drying stage to pause.

[0064] Step S306: After receiving the door opening signal, when receiving the door closing signal, the door lock is controlled to be locked, and the drying program is controlled to continue running.

[0065] Step S307: When the moisture content value is less than the first preset value, the on-off valve is controlled to be closed, the drying program is controlled to end, and the door lock of the clothes processing device is controlled to be unlocked.

[0066] In step S301, a reminder message is sent to remind the user that the care device 4 can be connected to the clothes that need to be ironed. The user decides whether to connect the care device 4 according to the actual situation. It should be noted that the clothes that need to be ironed can be special clothes that are not completely dried in the clothes processing device, or clothes that need to be ironed from other sources. In addition, special clothes refer to clothes that are easy to wrinkle, such as shirts.

[0067] If the user decides to connect the care device 4, the plug 41 of the care device 4 is connected to the exhaust port 2, and the first position detection structure sends a connection signal. After receiving the connection signal, the controller controls the on-off valve 3 to open, controls the door lock of the clothing processing device to unlock, and controls the drying program in the drying stage to pause, so that the user can open the door to take out the clothes that need ironing and care in the clothing processing device; when the user opens the door to take out the clothes and closes the door again, the controller receives the door opening signal sent by the second position detection structure when the door is opened, and receives the door closing signal sent by the second position detection structure when the door is closed again. After receiving the door closing signal, the controller controls the door lock to lock and controls the drying program to continue running. Since the processing drum usually rotates all the time during the drying stage, the user is likely to be injured when opening the door to take out the clothes during the rotation of the processing drum. By controlling the door lock and the drying program of the device, it is ensured that the drying program will not be executed when the user takes out the clothes, and the processing drum stops rotating, avoiding the rotation of the processing drum causing harm to the user, thereby improving the safety of the use of the clothing processing device. In addition, the present invention controls the door lock of the clothing processing device to be unlocked only in the late drying stage under the condition that the moisture content value is greater than or equal to the first preset value and less than or equal to the second preset value, thereby preventing users from being scalded.

[0068] Possibly, the specific setting methods of the second position detection structure include multiple ones, for example, the second position detection structure includes a second signal switch and a second signal contact, the second signal switch is arranged at the clothing delivery port of the casing / on the door body, and the second signal contact is arranged on the door body / at the clothing delivery port of the casing, when the door body is closed, the second signal switch contacts the second signal contact, thereby triggering a door closing signal, and when the door body is opened, the second signal switch separates from the second signal contact, thereby triggering a door opening signal. Of course, the above setting methods are only exemplary, as long as it is possible to send a door closing signal when the door body is closed and send a door opening signal when the door body is opened, the specific setting methods of the second position detection structure can be adjusted, and these adjustments do not deviate from the principles of the present invention and are within the protection scope of the present invention.

[0069] If the user does not need to connect the care device 4, no operation is required.
