[0041] In order to solve problems of wrinkles, peculiar smell or the like generated when the laundry is washed and exposed in an external environment for a long time, the application proposes a laundry treatment device. With reference to FIG. 1, it is a schematic diagram of specific structures of a laundry treatment device, the laundry treatment device comprises an operation control apparatus 10, a steam generation structure 20, an air blowing structure 30, a heating structure 40, and a drum 60.

[0042] Specifically, the operation control apparatus 10 is configured to control the steam generation structure 20, the air blowing structure 30, the heating structure 40 and the drum 60, thus all these structures are electrically connected to the operation control apparatus 10.

[0043] The drum 60 is provided with an air inlet, and the air inlet is docked with the steam generation structure 20, so that the steam generation structure 20 generates steam and conveys the steam into the drum 60 through the air inlet under control of the operation control apparatus 10.

[0044] The drum 60 is further provided with an air intake, and the air intake is docked with the air blowing structure 30, so that the air blowing structure 30 blows cold air into the drum 60 through the air intake under control of the operation control apparatus 10. Furthermore, the air blowing structure 30 is further connected to the heating structure 40, so that the heating structure heats air sucked by the air blowing structure 30 under control of the operation control apparatus 10, to provide hot air to the drum 60.

[0045] That is, the air blowing structure 30 always operates when it needs to blow air into the drum 60, hot air is blown into the drum 60 during operation of the heating structure 40, and cold air is blown into the drum 60 during non-operation of the heating structure 40.

[0046] It should be noted that the drum 60 is further provided with a laundry input port.

[0047] Based on function descriptions of the above structures, a control principle of the operation control apparatus 10 is as follows.

[0048] When laundry is put into the drum 60, the steam generation structure 20 is first controlled to continuously provide steam to the drum 60, to remove wrinkles and peculiar smell on the laundry; then, the air blowing structure 30 is controlled to provide cold air to the drum 60 for a period of time, to reduce system temperature; and finally, the air blowing structure 30 and the heating structure 40 are controlled to provide hot air to the laundry in the drum 60, to dry the laundry.

[0049] Based on the above descriptions, achievable technical effects are: wrinkles and peculiar smell on the laundry in the drum are removed by introducing steam into the laundry, temperature of the drum is increased at this time, so that the system temperature of the laundry treatment device is also high, noise is large when other structures in the device are started and operate; according to the application, the system temperature is reduced by further introducing cold air into the drum for a period of time, so that starting and operation noise of other structures is reduced, and finally, hot air is introduced into the laundry in the drum, to achieve a purpose of drying the laundry.

[0050] In some embodiments, as shown in FIG. 1, the laundry treatment device may further comprise a filter 50 which is connected to an air outlet of the drum 60 and configured to filter attachments on the laundry carried by cold air and hot air.

[0051] In order for those skilled in the art to understand the solutions of the application better, the technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application.

First embodiment



[0052] FIG. 2 is a schematic flowchart of an embodiment of a laundry treatment method shown according to an exemplary embodiment of the application, the laundry treatment method is applied to the operation control apparatus 10 in the laundry treatment device as shown in FIG. 1. As shown in FIG. 2, the laundry treatment method comprises the following operations 201 to 203.

[0053] At 201, steam is provided to laundry in a drum of the laundry treatment device, to remove wrinkles and peculiar smell on the laundry.

[0054] In an optional embodiment, a material type of the laundry put by a user in the drum is obtained, and a steam duration and a first heating duration are determined according to the material type, and steam is continuously provided to the laundry in the drum for the steam duration.

[0055] In an optional embodiment, the laundry treatment device is usually provided with a display panel for the user to operate, and selection buttons of a variety of different processing programs and/or selection buttons of laundry material types are provided on the display panel, for example, selection buttons of laundry material types such as "shirt/silk/mink", "cashmere type", "school uniform type", "suit/wind clothes type", "cotton and linen/large piece", or the like are provided on the display panel.

[0056] Based on this, when the user opens an inlet of the drum to put the laundry in the drum, a signal that the laundry is put in the inlet of the drum may be detected, then reception of a selection signal that the user presses the selection button of the laundry material type on the display panel is triggered, and the material type of the laundry put by the user is obtained based on the received selection signal.

[0057] Before operation 201 is executed, steam operation parameters and hot air operation parameters of laundry with different material types may be determined in advance by way of experimental calibration, and steam duration and first heating duration corresponding to each material type obtained by the experimental calibration are added to a control parameter library, to facilitate direct search and usage subsequently.

[0058] Based on this, in the control parameter library obtained in advance, the steam duration and first heating duration corresponding to the material type selected by the user are searched.

[0059] In the embodiment of the application, the steam duration represents a duration required for continuously introducing steam into the laundry in the drum. The first heating duration is a duration for providing hot air to the laundry in the drum.

[0060] Optionally, high-temperature steam may be provided to the drum, to achieve an effect of wetting the laundry, while the laundry is sterilized, ironed, heated, and roughness of fibers are smoothed.

[0061] It should be noted that steam durations required by the laundry with different material types are different. For example, the laundry with shirt/silk/mink, cashmere and school uniform types which belong to a small fiber hole material type are not suitable for long-time steam, and when the steam time is too long, it may damage the laundry; and the laundry with suit/wind clothes, cotton and linen/large piece types which belong to a large fiber hole material type require steam to be introduced for a long time, so that treatment effect may be ensured.

[0062] At 202, cold air is provided to the drum for a first preset duration, to reduce system temperature.

[0063] Based on the above descriptions of operation 201, after the laundry in the drum are fumigated by the high-temperature steam, temperature of the whole system is high, and when hot air is directly introduced for drying, operation noise of other structures in the laundry treatment device is high, especially for a compressor in the system. There are many mechanical structures arranged inside the closed system, and starting noise thereof may be high due to high temperature expansion. Therefore, temperature of the whole system is reduced by further introducing cold air into the drum for a period of time, so that starting and operation noise of other structures is reduced. Then, hot air is introduced to dry the laundry, and operation noise of the whole system is small.

[0064] Optionally, the time for providing cold air to the drum may be set according to practical experience, for example, the preset duration may be set to be 10 minutes.

[0065] At 203, hot air is provided to the laundry in the drum, to dry the laundry.

[0066] Specifically, based on the above descriptions of operation 201, hot air may be continuously provided to the laundry in the drum for the first heating duration, to dry the laundry.

[0067] With the above treatment solution, when oil stains exist on the laundry, a cleaning agent may also be applied to an area with the oil stains, the laundry is wetted by steam, then the laundry is blown and dried through hot air, so that mild oil stains of the laundry may be further removed, such manner is particularly suitable for furs which are not suitable for washing in water.

[0068] In an optional embodiment, after hot air is provided to the laundry in the drum, cold air may also be provided to the drum for a second preset duration, to reduce temperature of the laundry, so that the user is not scalded when the user takes the laundry out of the drum, and may directly try on the laundry.

[0069] Preferably, the second preset duration may be less than the above first preset duration required for reducing the system temperature.

[0070] It should be noted that in the whole treatment process of the laundry, the drum may be controlled to rotate in a forward direction and a reverse direction alternately, so that the laundry is always in a shaken and loose state in the whole treatment process, to ensure that laundry treatment application conditions (i.e., introducing steam, blowing cold air, blowing hot air) are in full contact with the laundry, and achieve an optimal treatment effect.

[0071] In a particular implementation, the drum may rotate in the reverse direction for a period of time, every a certain period.

[0072] For example, the drum rotates once in the reverse direction, every 5 minutes.

[0073] So far, the treatment process shown in FIG. 2 is completed. According to the treatment process shown in FIG. 2, wrinkles and peculiar smell on the laundry in the drum are removed by introducing steam into the laundry, temperature of the drum is increased at this time, so that the system temperature of the laundry treatment device is also high, noise is large when other structures in the device are started and operate; according to the application, the system temperature is reduced by further introducing cold air into the drum for a period of time, so that starting and operation noise of other structures is reduced, and finally, hot air is introduced into the laundry in the drum, to achieve a purpose of drying the laundry.

Second embodiment



[0074] FIG. 3 is a schematic flowchart of an embodiment of another laundry treatment method shown according to an exemplary embodiment of the application. Based on the embodiment shown in FIG. 2, as shown in FIG. 3, the laundry treatment method comprises the following operations 301 to 306.

[0075] At 301, a material type of the laundry in the drum is obtained.

[0076] The process of operation 301 may refer to relevant descriptions in the above embodiment, which are not elaborated here.

[0077] At 302, it is determined whether the drum needs to be preheated according to the material type. If yes, operation 303 is performed; if no, operation 304 is performed.

[0078] In an optional specific embodiment, the laundry belonging to the large fiber hole type has large fiber holes at a surface thereof, for example, suit/wind clothes, cotton and linen/large piece types belong to the large fiber hole type, when steam is directly introduced into the laundry at normal temperature, it is not easy for the steam to directly go deep into the laundry; the laundry belonging to the small fiber hole type has small fiber holes at a surface thereof, for example, shirt/silk/mink, cashmere and school uniform types belong to the small fiber hole type, even though steam is introduced into the laundry at normal temperature, it is easy for the steam to go deep into the laundry.

[0079] Based on this, when the material type belongs to the large fiber hole type, it is determined that the drum needs to be preheated; and when the material type belongs to the small fiber hole type, it is determined that the drum does not need to be preheated.

[0080] At 303, a second heating duration corresponding to the material type is obtained, and hot air is continuously provided to the drum for the second heating duration.

[0081] The second heating duration is a duration for supplying hot air into the drum, to preheat the drum.

[0082] In the embodiment, in order to further improve the treatment effect of the laundry, the drum may be preheated in advance, to improve an effect of introducing steam deep into the laundry subsequently, and thus promote an effect of drying the laundry with hot air.

[0083] In some embodiments, experimental calibration may also be used in a process of obtaining the second heating duration corresponding to the material type, and a corresponding second heating duration is preset for the material type belonging to the large fiber hole type, so that the second heating duration corresponding to the material type may be directly obtained.

[0084] Furthermore, preheating durations required for different material types are also different, for example, a preheating duration required for the material type of suit/wind clothes is shorter than a preheating duration required for the material type of cotton and linen/large piece.

[0085] At 304, a steam duration and a first heating duration are determined according to the material type, and steam is continuously provided to the drum for the steam duration, to remove wrinkles and peculiar smell on the laundry.

[0086] At 305, cold air is provided to the drum for a first preset duration, to reduce system temperature.

[0087] At 306, hot air is continuously provided to the laundry in the drum for the first heating duration, to dry the laundry.

[0088] Processes of operations 304 to 306 may refer to relevant descriptions in the above embodiment, which are not elaborated here.

[0089] So far, the treatment process shown in FIG. 3 is completed. According to the treatment process shown in FIG. 3, in order to further improve the treatment effect of the laundry, in order to further improve the treatment effect of the laundry, the drum may be preheated in advance for a period of time, to improve an effect of introducing steam deep into the laundry subsequently, and remove wrinkles and peculiar smell molecules on the laundry better.

Based on the embodiments shown in FIG. 2 and FIG. 3, as shown in FIG. 4, the laundry treatment method comprises the following operations 401 to 403.

[0091] At 401, steam is provided to laundry in the drum, to remove wrinkles and peculiar smell on the laundry.

[0092] At 402, cold air is provided to the drum for a first preset duration, to reduce system temperature.

[0093] Processes of operations 401 and 402 may refer to relevant descriptions in the above embodiments, which are not elaborated here.

[0094] At 403, the laundry in the drum is blown with alternate circulation of cold air and hot air, to remove attachments, peculiar smell and wrinkles on the laundry better while dry the laundry.

[0095] Under an action of blowing the laundry wetted by steam with alternate circulation of cold air and hot air, non-persistent and solidified dust mites, smoke odor, hot pot odor or other peculiar smell molecules, and attachments attached to the laundry may be carried away by alternate circulation of cold air and hot air. Meanwhile, under an action of blowing force of cold air and hot air, wrinkles and roughness of fibers on the laundry may be smoothed, so that the laundry is fluffier and softer, and ready to be used and worn immediately, thereby achieving light dry-cleaning treatment function of the laundry.

[0096] It should be noted that alternate manners of cold air and hot air may be that hot air is blown first, and then cold air is blown, or cold air is blown first, and then hot air is blown, which is not specifically limited in the application.

[0097] It should be further noted that in a process of blowing the laundry with alternation of cold air and hot air, time for blowing hot air may be different each time, and correspondingly, time for blowing cold air may also be different each time.
