Description

Technical Field

[0001] The present invention relates to the technical field of clothes dryers, and in particular provides a clothes dryer and a control method thereof. Background Art

[0002] When clothes and quilts are dried in the sun, they will produce a special "sunshine smell". In recent years, scientific research has shown that the smell of sunshine is produced by the chemical reaction of aldehydes, ketones, carboxylic acids and other organic compounds when light shines on clothes or quilts.

[0003] Existing clothes dryers use artificially formulated fragrances to create the smell of sunshine, but the smell produced in this way is different from the real smell of sunshine, and is not the real natural smell of sunshine. The drying odor enhancement control method disclosed in the patent document "CN113445280A" includes: according to the instruction to enter the drying odor enhancement operation mode, controlling the motor to rotate and the heater to turn on, so as to perform a drying operation on the objects to be dried that are turned over in the drum; and turning on the ultraviolet lamp group to emit ultraviolet rays to irradiate the objects to be dried, and the wavelength of the ultraviolet rays is within the range of 265nm to 390nm; its control method is to turn on the ultraviolet lamp group to irradiate the clothes shortly after the drying work starts. Since the drying work has just started and the duration is not long, the clothes are still in a relatively wet state. In this case, turning on the ultraviolet lamp group will waste the use cost of the equipment; turning on the ultraviolet lamp group to irradiate the clothes after the drying work is completed will prolong the working time of the equipment, which brings a poor experience to the user.

[0004] In summary, the existing way of making clothes smell like sunshine in dryers will increase the cost of use and the long working time will give users a bad experience.

[0005] Accordingly, the art requires a new clothes dryer and a control method thereof to solve the above problems. Summary of the invention

[0089] The difference between the clothes dryers in the above four preferred embodiments is only the light emitted by the light source device 1. The rest of the structures and settings are the same and will not be described in detail here.

[0090] It should be noted that the present invention does not impose any restrictions on the specific location of the light source device 1 and the lens 2 on the clothes dryer and the connection method with the clothes dryer. Figure 1The direction shown is the reference direction. The light source device 1 can be embedded in the door body 52, or connected to the door body 52 by screws or bolts. The light source device 1 and the lens 2 can also be embedded in the inner wall of the rotating drum 51 and rotate with the rotating drum 51. When the rotating drum 51 stops, the rotation angle of the rotating drum 51 is adjusted so that the light source device 1 and the lens 2 are located above the clothes in the rotating drum 51 to illuminate the clothes and produce a sunshine smell. Those skilled in the art can set it according to actual conditions.

[0091] Furthermore, the clothes dryer comprises an adjusting component 3 , and the lens 2 is arranged inside the body of the clothes dryer through the adjusting component 3 . The adjusting component 3 is arranged so that the lens 2 can be movably adjusted relative to the light source device 1 .

[0092] See also Figure 2 ,like Figure 2 As shown, as a first preferred embodiment of the adjustment component 3, the adjustment component 3 includes a first sliding member 31, a second sliding member 32, a driving member 33 and a moving member 34, the light source device 1 includes a plurality of light source lamps 11 and a fixed plate 12, the plurality of light source lamps 11 are arranged on the fixed plate 12, a receiving cavity 121 is arranged on the fixed plate 12, the driving member 33 is arranged in the receiving cavity 121, the driving member 33 is connected to the moving member 34, the moving member 34 is connected to the first sliding member 31, the first sliding member 31 and the second sliding member 32 are slidably connected, the second sliding member 32 is fixedly connected to the lens 2, and the lens 2 is connected to the driving mechanism (Not shown in the figure), the driving mechanism can be a motor driving mechanism or a hydraulic driving mechanism, and the driving mechanism drives the lens 2 to move forward and backward; a plurality of lamp slots 21 are arranged on the lens 2, and the number of the lamp slots 21 and the light source lamp 11 are the same, and they are arranged one by one, and the driving member 33 can drive the moving member 34 to move up and down. In the initial state, the light source lamp 11 is placed in the lamp slot 21. When the moving member 34 moves upward, the lamp slot 21 and the light source lamp 11 are separated. After the moving member 34 moves a preset distance, the driving mechanism drives the lens 2 to move, and the first sliding member 31 and the second sliding member 32 are used to realize the forward and backward movement of the lens 2.

[0093] The first sliding member 31 is a slide groove, and the second sliding member 32 is a slider matching the slide groove. Of course, this is only a preferred setting method. The first sliding member 31 can also be a slide rail, and the second sliding member 32 can be a slider matching the slide rail. The first sliding member 31 and the second sliding member 32 can also be other matching structures. Those skilled in the art can set them according to actual conditions.

[0094] The driving member 33 is a driving motor, which is connected to a screw (not shown in the figure), and the moving member 34 is sleeved on the screw. The moving member 34 is provided with a thread matching the screw. The screw rotates to move the moving member 34 up and down, thereby realizing the up and down movement of the lens 2. Of course, this is only a preferred setting mode. Alternatively, the driving member 33 may be a hydraulic cylinder, and the moving member 34 may be a telescopic rod. The hydraulic cylinder drives the telescopic rod to move telescopically to realize the up and down movement of the lens 2. Those skilled in the art may set it according to actual conditions.

[0095] Multiple lamp grooves 21 correspond to multiple light source lamps 11 one by one, and the lamp grooves 21 are recessed toward the direction of the lens 2. The surface of the lamp grooves 21 is a plurality of diamond-shaped protrusions (not shown in the figure). The plurality of diamond-shaped protrusions are circumferentially arranged around the center of the lamp grooves 21 to form a refraction circle. There are multiple refraction circles, and the centers of the multiple refraction circles are the same. Based on this, the refraction of light is realized through the structure of the multiple lamp grooves 21, so that the angle of the light emitted by the light source lamp 11 is adjusted and then irradiated onto the clothes in the rotating drum 51.

[0096] It should be noted that the present invention does not impose any limitation on the specific structures of the lens 2 and the lamp trough 21. Any lens structure that can adjust the irradiation angle of light in the prior art can be used, and those skilled in the art can set it according to actual conditions.

[0097] The following example illustrates how the adjustment component 3 adjusts the movement of the lens 2 relative to the light source device 1. Figure 2 , 5 6, the driving member 33 drives the moving member 34 to move upward, so that the lens 2 moves upward, the light source lamp 11 and the lamp slot 21 are separated, and the state is as follows Figure 5 As shown in FIG. , the driving mechanism (not shown in the figure) then drives the lens 2 to move forward to Figure 6 As shown in the figure, the distance that the lens 2 moves forward is the distance between two adjacent lamp slots 21, and then the driving member 33 drives the moving member 34 to move downward to restore the original position, the light source lamp 11 is placed in the lamp slot 21, and the first sliding member 31 and the second sliding member 32 are placed in the accommodating cavity 121. Based on this adjustment, the correspondence between the light source lamp 11 and the lamp slot 21 and the translation of the lens 2 are changed to achieve the adjustment of the light irradiation angle and the translation of the irradiation area. During the adjustment process, it is sufficient to ensure that the distance that the lens 2 moves forward and backward is a multiple of the distance between the two adjacent lamp slots 21.

[0098] Furthermore, the light source lamp 11 includes a first lamp 111, a second lamp 112 and a third lamp 113. The first lamp 111 can emit visible light that makes clothes smell like sunshine, the second lamp 112 can emit infrared rays, and the third lamp 113 can emit UVC band ultraviolet rays. The first lamp 111, the second lamp 112 and the third lamp 113 are located in the middle of the plurality of light source lamps 11, so that no matter whether the lens 2 moves forward or backward, there is a lamp slot 21 corresponding to the first lamp 111, the second lamp 112 and the third lamp 113.

[0099] In the first preferred embodiment of the adjustment component 3, as Figure 2 As shown, the number of the first sliding member 31, the second sliding member 32, the driving member 33 and the moving member 34 are all two, and they are symmetrically distributed. In the adjustment component 3 of the second preferred embodiment, as shown in FIG. Figure 3 As shown, the number of the driving member 33 and the moving member 34 are both one, the left and right ends of the moving member 34 extend upward to connect to the left and right first sliding components 31 respectively, and the middle part of the moving member 34 extends downward to connect to the driving member 33. Based on this, the left and right ends of the moving member 34 maintain synchronous movement to prevent the lens 2 from tilting.

[0100] See also Figure 4 The adjustment assembly 3 of the third preferred embodiment only includes a first sliding member 31 and a second sliding member 32 . In this case, only the front-rear movement of the lens 2 relative to the light source device 1 is realized.

[0101] See also Figure 7 The adjustment component 3 of the fourth preferred embodiment includes a driving member 33, a moving member 34, a ball head 35 and a connecting column 36. The driving member 33 and the moving member 34 are connected, and there are two of them, which are symmetrically distributed on the left and right sides. The moving member 34 is movably connected to the lens 2, the driving member 33 is connected to the fixed plate 12, the connecting column 36 is connected to the lens 2, and the connecting column 36 is movably connected to the fixed plate 12 through the ball head 35; one of the driving members 33 on the left and right sides drives the moving member 34 to move downward, and the other of the driving members 33 on the left and right sides drives the moving member 34 to move upward, so as to realize the rotation adjustment of the lens 2 around the ball head 35, and then realize the angle adjustment of the light emitted by the light source lamp 11.

[0102] Furthermore, in the present invention, the clothes dryer also includes a seal 4, a gap is formed between the lens 2 and the light source device 1, the seal 4 seals the gap, and the seal 4 is configured to be retractable or deformable; the seal 4 surrounds the light source device 1 and the lens 2 to seal the gap between the light source device 1 and the lens 2, to prevent water vapor or water droplets from entering the light source device 1, and to prevent malfunctions from occurring.

[0103] exist Figures 2 to 7 In the preferred embodiment, the seal 4 is included. Figures 2 to 6 Not shown in Figure 7 The third preferred embodiment is used as an example to illustrate the seal 4. Figure 7 As shown, the fixing plate 12 is provided with a first connecting portion 122 surrounding the fixing plate 12, and a first fixing portion 41 is provided below the sealing member 4. The first fixing portion 41 is sleeved onto the first connecting portion 122, and a first clamping block 1221 is provided on the first connecting portion 122. The first clamping block 1221 is provided on the first fixing portion 41, and a first clamping hole matching the first clamping block 1221 is provided on the first fixing portion 41. The first connecting portion 122 and the first fixing portion 41 are fixed by the first clamping block 1221 and the first clamping hole, thereby fixing the sealing member 4 to the light source device 1. A second connecting portion 22 surrounding the lens 2 is provided on the mirror 2, a second fixing portion 42 is provided above the sealing member 4, the second fixing portion 42 is sleeved onto the second connecting portion 22, a second clamping block 221 is provided on the second connecting portion 22, a second clamping hole matching the second clamping block 221 is provided on the second fixing portion 42, the second connecting portion 22 and the second fixing portion 42 are fixed by the second clamping block 221 and the second clamping hole, and then the sealing member 4 and the lens are fixed; based on this, the sealing member 4 seals the light source device 1 and the lens 2.

[0104] It should be noted that the present invention does not show any connection method between the seal 4 and the light source device 1 and the lens 2. The seal 4 and the fixing plate 12 may be connected by screws, and the seal 4 and the lens 2 may be connected by screws or by bonding. The technicians in this field may set it according to the actual situation.

[0105] Furthermore, the seal 4 is a retractable elastic sealing structure and a cylindrical structure. Of course, this is not restrictive. The seal 4 can also be a waterproof cloth. When the lens 2 and the light source device 1 are not moving relative to each other and are in the original state, the waterproof cloth is in a loose or folded state so as not to hinder the movement of the lens 2.

[0106] See next Figure 1 ,like Figure 1 As shown, the clothes dryer further includes a heat dissipation device 6, which is connected to the light source device 1 and is used to dissipate heat from the light source device 1. The heat dissipation device 6 can be a fan, a heat dissipation plate, or other types of radiators, and those skilled in the art can set it according to actual conditions.

[0107] In addition, in the present invention, the lens 2 is configured to make the irradiation angle of the light source device 1 less than 180 degrees, thereby avoiding waste of light emitted by the light source device 1, making it easier for clothes to produce a sunshine smell, and having a gain effect on the clothes producing a sunshine smell.

[0108] Further, in the present invention, the wavelength of the visible light emitted by the light source device 1 is preferably 400nm-780nm. The use of visible light in this wavelength can make clothes smell like sunshine, and the effect of making clothes smell like sunshine is significant. Of course, this is not restrictive. The specific value of the wavelength of the visible light emitted by the light source device 1 can be set by those skilled in the art according to actual conditions.

[0109] Furthermore, the light source device 1 is configured to have an adjustable illumination intensity. Specifically, the illumination intensity of the light source device 1 can be adjusted by adjusting the power of the light source device 1. When the power of the light source device 1 increases, the illumination intensity of the light source device 1 increases, and when the power of the light source device 1 decreases, the illumination intensity of the light source device 1 decreases.

[0110] In addition, in the present invention, the light source device 1, the lens 2 and the heat dissipation device 6 are all embedded in the door body 52. ​​When the lens 2 and the light source device 1 do not move relative to each other and are in the original state, the outer surface of the lens 2 is flush with the surface of the door body 52, thereby improving the aesthetics of the equipment.

[0111] In another preferred embodiment, the clothes dryer does not include the adjustment component 3, the lens 2 is fixedly connected to the light source device 1, and the light emitted by the light source device 1 is fixedly adjusted to a certain area in the rotating drum 51, such as Figure 1 As shown in , the irradiation area of ​​the light source device 1 can be adjusted to the irradiation area Q by the lens 2, Figure 1 The shaded part in the middle is clothing; regarding the adjustment angle of the irradiation direction of the light source device 1, those skilled in the art can set it according to actual conditions.

[0112] In another preferred embodiment, the light source device 1 is connected to the door body 52, and the lens 2 is connected to the door body 52 through the adjustment component 3, that is, the fixed plate 12 is a part of the door body 52; the light source device 1 can be the fixed plate 12 and the light source lamp 11, or it can be just the light source lamp 11. The specific conductive circuit of the light source device 1 is not shown in the present invention, and those skilled in the art can set it according to actual conditions.

[0113] In summary, the present invention can make clothes smell like sunshine without damaging the clothes, and through the setting of the lens 2, the light emitted by the light source device 1 can be adjusted to a fixed area to improve the lighting effect.

[0114] The light source device 1 of the present invention can emit light that makes clothes smell like sunshine, which is visible light or a combination of visible light and infrared light or a combination of visible light and ultraviolet light in the UVC band or a combination of visible light, infrared light and ultraviolet light in the UVC band.

[0115] Furthermore, the clothes dryer of the present invention further comprises a controller, wherein the controller is configured to control all operations of the clothes dryer.

[0116] Those skilled in the art will appreciate that the present invention does not impose any limitation on the specific structure and model of the controller, and the controller may be either an original controller of the dryer or a separate controller configured to execute the control method of the present invention. Technicians may set the structure and model of the controller according to actual usage requirements.

[0117] See next Figure 8 ,like Figure 8 As shown, the control method of the clothes dryer of the present invention mainly includes the following steps:

[0118] Step S1: when the clothes dryer is performing drying work, obtaining the remaining time of the drying work;

[0119] Step S2: comparing the remaining duration of the drying operation with the first preset duration;

[0120] Step S3: Based on the comparison result, selectively control the light source device to turn on.

[0121] Furthermore, in step S1, when the user selects the dryer to perform the drying work, the remaining time of the drying work can be read through the display on the dryer, or the humidity of the clothes can be obtained through the sensor, and the remaining time of the drying work can be determined according to the humidity of the clothes. In step S2, the calculation module compares the remaining time of the drying work with the first preset time. If the remaining time of the drying work is less than or equal to the first preset time, the first comparison result is output to the controller. If the remaining time of the drying work is greater than the first preset time, the second comparison result is output to the controller. Then in step S3, if it is the first comparison result, the light source device 1 is controlled to turn on, and if it is the second comparison result, the light source device 1 is controlled to remain turned off.

[0122] Based on the above control method, after the drying work has been carried out for a period of time, the humidity of the clothes becomes low. At this time, turning on the light source device 1 to irradiate the clothes can produce a sunlight smell on the clothes, which has a gain effect. On the premise of ensuring that the clothes are fully irradiated, it is possible to avoid turning on the light source in advance to irradiate the clothes and increase the use cost. At the same time, the working time of the dryer can be controlled within a reasonable range, thereby improving the user experience.

[0123] Preferably, the first preset time length is 30 minutes. Of course, this is not restrictive. The first preset time length can also be 20 minutes or other values. Those skilled in the art can set it according to actual conditions.

[0124] In another preferred embodiment, the first preset duration is less than or equal to half of the total drying operation duration.

[0125] See next Fig. 9 ,like Fig. 9 As shown, a control method of a preferred embodiment of the present invention includes the following steps:

[0126] Step S101: when the clothes dryer is performing drying work, obtaining the remaining time of the drying work;

[0127] Step S102: comparing the remaining duration of the drying operation with the first preset duration;

[0128] Step S103: If the remaining time of the drying operation is less than or equal to the first preset time, the light source device is controlled to turn on;

[0129] Step S104: if the remaining time of the drying operation is greater than the first preset time, controlling the light source device to remain turned off;

[0130] Step S105: if the light source device is in the on state, then after a second preset time period, the light source device is controlled to be turned off;

[0131] Step S106: when the light source device is in the on state, controlling the rotating drum of the clothes dryer to rotate intermittently;

[0132] Step S1061: Controlling the rotating drum to rotate by a first preset angle at intervals of a third preset time length;

[0133] Step S1062: After the rotating drum has intermittently rotated for a fourth preset time period, the rotating drum stops rotating.

[0134] Further, in step S101, when the user selects the dryer to perform the drying work, the remaining time of the drying work can be read through the display on the dryer, or the humidity of the clothes can be obtained through the sensor, and the remaining time of the drying work can be determined according to the humidity of the clothes. In step S2, the calculation module compares the remaining time of the drying work with the first preset time. If the remaining time of the drying work is less than or equal to the first preset time, the first comparison result is output to the controller. If the remaining time of the drying work is greater than the first preset time, the second comparison result is output to the controller.

[0135] If the controller receives the first comparison result, the remaining time of the drying work is less than or equal to the first preset time, which proves that the drying work has been carried out for a period of time and the humidity of the clothes has been greatly reduced, then the process enters step S103 and the light source device 1 is controlled to be turned on. If the controller receives the second comparison result, the remaining time of the drying work is greater than the first preset time, which proves that the drying work has not been completed and the humidity of the clothes is still in a relatively wet state. If the light source device 1 is controlled to be turned on at this time, not only will there be no gain in sunlight to the clothes, but the cost of use will also be increased. Therefore, the process enters step S104 and the light source device 1 is controlled to remain in the off state.

[0136] Further, in step S105, after the light source device 1 is turned on, it continues to work for a second preset time period and then controls the light source device to turn off, wherein the second preset time period is greater than the first preset time period to ensure that after the drying work is completed, the light source device 1 still illuminates the clothes to enhance the sunlight gain effect of the clothes.

[0137] Furthermore, in step S106, when the light source device 1 is in the on state, the rotating drum 51 is controlled to rotate intermittently, so that the clothes are tumbled in the rotating drum 51, so as to change the light source device 1 to illuminate different areas of the clothes, so that the clothes can be fully and comprehensively illuminated, which is beneficial to enhance the sunshine smell of the clothes.

[0138] Further, step S106 includes step S1061 and step S1062. In step S1061, the rotating drum 51 is rotated to a first preset angle every 5 minutes. After the rotating drum 51 completes its rotation, the rotating drum 51 is rotated to the first preset angle every 5 minutes. In step S1062, after the rotating drum 51 has worked intermittently for 15 minutes, the rotating drum 51 is controlled to stop rotating.

[0139] Those skilled in the art can understand that the third preset time length of 5 minutes and the fourth preset time length of 15 minutes are merely preferred settings. The third preset time length can also be 3 minutes, 4 minutes or other values. The fourth preset time length only needs to be less than the second preset time length to ensure that after the rotating drum 51 stops rotating, the light source device 1 can still illuminate the clothes for a period of time to promote the clothes to produce a sunny smell.

[0140] In a preferred embodiment, the first preset angle is 180°. Of course, this is not restrictive. The first preset angle can also be 90°, 120°, 180° or other values, as long as the first preset angle is between 0°-360°. Technical personnel in this field can set it according to actual conditions. The first preset angle is between 0°-360°, and the first preset angle is not greater than 360°. This saves usage costs while ensuring that the clothes are turned over.

[0141] In another preferred embodiment, the first preset angle is greater than 360°.

[0142] See next Fig.10 ,like Fig.10 As shown, the detailed steps of how to control the illumination intensity of the light source device 1 are as follows:

[0143] Step S201: obtaining the material of the clothes inside the dryer;

[0144] Step S202: controlling the illumination intensity of the light source device according to the material of the clothing;

[0145] Step S2021: if the material of the clothing is cotton, controlling the illumination intensity of the light source device to be a first illumination intensity;

[0146] Step S2022: If the material of the clothing is silk or fur, the illumination intensity of the light source device is controlled to be a second illumination intensity.

[0147] In step S201, the user can manually select or input the material of the clothes through the controller or control panel of the dryer, and the controller receives and obtains the material of the clothes inside the dryer, or the material of the clothes can be obtained through a clothing material recognition device in the prior art.

[0148] In step S202, the illumination intensity of the light source device 1 is controlled accordingly according to the material of different clothes. If the material of the clothes is not easily exposed to strong light, the illumination intensity of the light source device 1 is reduced, and the power of the light source device 1 is controlled to be reduced. If the material of the clothes is easily exposed to strong light, the illumination intensity of the light source device 1 is increased, and the power of the light source device 1 is controlled to be increased.

[0149] Further, step S202 includes step S2021 and step S2022. In step S2021, if the material of the clothes is cotton, the illumination intensity of the light source device 1 is controlled to be a first illumination intensity. In step S2022, if the material of the clothes is silk or fur, the illumination intensity of the light source device 1 is controlled to be a second illumination intensity, wherein the first illumination intensity is an illumination intensity at which cotton clothes will not fade or be damaged after long-term exposure, and the second illumination intensity is less than the first illumination intensity.

[0150] In another preferred embodiment, step S202 includes only one of step S2021 and step S2022.

[0151] In another preferred embodiment, when the light source device 1 is turned on, the rotating drum 51 of the clothes dryer is controlled to rotate back and forth at a second preset angle. Specifically, after the light source device 1 is turned on, the rotating drum 51 is controlled to rotate clockwise at the second preset angle first, and then the rotating drum 51 is controlled to rotate counterclockwise at the second preset angle, and then rotate back and forth in sequence, so that the clothes are constantly tumbled back and forth, and different areas of the clothes are irradiated to produce a sunshine smell, thereby enhancing the sunshine smell effect of the clothes.

[0152] It should be noted that the present invention does not impose any limitation on the specific numerical value of the second preset angle. The value range of the second preset angle is between 0° and 360°, and those skilled in the art can set it according to actual conditions.

[0153] In a second aspect, the present invention further claims a clothes dryer, the clothes dryer comprising a controller, wherein the controller is configured to execute the control method according to any one of the above preferred embodiments.

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.
