Description

Technical Field

[0002] With the rapid development of washing machine technology, washing machines have become increasingly feature-rich, offering more and more functions in addition to the standard washing, rinsing, and spin-drying functions.

[0003] In existing washing machine drying duct designs, the fan is connected to the drying duct heating element. The workflow is as follows: the fan blows air into the drying duct, the air is heated by the heating element, and then enters the drum to dry the clothes. At this time, the air pressure inside the drum is higher than the outside air pressure. The hot and humid air after drying is discharged from the exhaust port at the bottom of the drum due to the pressure difference. However, this solution mainly relies on high-temperature hot air to force the evaporation of moisture, which can easily cause uneven temperature inside the washing drum, resulting in localized high temperature damage to the clothes, causing the clothing fibers to shrink, fade, or deform. In addition, the fan speed is high, the noise is loud, the energy consumption is high, and the drying efficiency is poor, affecting the user experience.

[0004] Therefore, it is necessary to provide a new approach to solve the aforementioned technical problems. Utility Model Content

[0040] Compared with the prior art, the beneficial effects of the embodiments of this utility model are as follows:

[0041] This invention provides a garment care device that uses a negative pressure generator to create a negative pressure environment by drawing air from inside the washing drum. This causes airflow within the drum to move outwards, while the air, heated by natural atmospheric pressure, passes through a drying tunnel assembly and enters the drum to dry the clothes. The negative pressure environment lowers the boiling point of water, enabling rapid evaporation even at lower temperatures. This makes it easier to remove moisture from the clothes, effectively improving drying efficiency and reducing heat damage. By placing the drying tunnel assembly at the front of the drum and the negative pressure generator at the rear, a high-speed airflow is created within the drum, flowing from front to back. Optimizing the airflow path accelerates moisture removal and effectively ensures uniform temperature inside the drum, preventing localized high temperatures from damaging clothes. This improves drying efficiency and energy saving, enhancing the user experience. By installing multiple negative pressure generators at different locations within the washing drum, humid and hot air is drawn from different directions, creating various drying airflows and stronger air movement. This provides multiple drying modes and diverse drying functions. Furthermore, the multiple negative pressure generators ensure that the drying airflow covers all parts of the clothes, optimizing drying uniformity, accelerating moisture evaporation, shortening drying time, and effectively improving drying efficiency.

[0062] Example 1

[0063] This utility model embodiment provides a garment care device 1, combined with... Figures 1-6 As shown, it includes:

[0064] 10 washing drums;

[0065] A drying structure is installed with the washing drum 10; the drying structure includes a drying tunnel assembly 20 for heating to form a drying airflow and a negative pressure generating device 30 for forming a negative pressure environment inside the washing drum 10.

[0066] The drying tunnel assembly 20 is connected to the front end of the washing drum 10, and the negative pressure generating device 30 is connected to the rear end of the washing drum 10;

[0067] The washing drum 10 is under negative pressure under the action of the negative pressure generating device 30, and the outside air enters the washing drum 10 after being heated by the drying tunnel assembly 20 to form a drying airflow.

[0068] Among them, at least two of the negative pressure generating devices 30 are configured to form multiple drying airflow paths within the washing drum 10 by adjusting them to achieve different working modes.

[0069] Combination Figure 1 The direction of the drying airflow indicated by the middle arrow is as follows: In this embodiment, the negative pressure generating device 30 draws air from the washing drum 10 to create a negative pressure environment, thereby causing the airflow inside the washing drum 10 to flow to the outside. At the same time, the air is heated by the drying tunnel assembly 20 under natural air pressure and enters the washing drum 10 to dry the clothes. The negative pressure environment inside the washing drum 10 lowers the boiling point of water, enabling rapid evaporation of moisture even at lower temperatures. The moisture on the clothes is more easily removed, effectively improving drying efficiency and reducing heat damage.

[0070] By placing the drying tunnel assembly 20 at the front end of the washing drum 10 and the negative pressure generating device 30 at the rear end of the washing drum 10, a high-speed airflow is formed inside the washing drum 10 from the front to the rear, optimizing the airflow path, accelerating the removal of moisture, further ensuring a uniform temperature inside the drum, avoiding local high temperature damage to clothes, and achieving the effect of improving drying efficiency and energy saving.

[0071] By setting multiple negative pressure generating devices 30 at different positions in the washing drum 10, humid and hot air inside the washing drum 10 can be drawn from different directions, forming multiple drying airflows inside the washing drum 10 and creating stronger airflow, thereby providing multiple drying modes and realizing diversified drying functions. Furthermore, the multiple negative pressure generating devices 30 can make the drying airflow cover all parts of the clothes, optimize drying uniformity, accelerate the moisture evaporation rate, shorten the drying time, and effectively improve drying efficiency.

[0072] In some embodiments, the negative pressure generating device 30 is installed at the bottom 11 of the washing drum 10 to make full use of the rear space of the garment care device 1 housing and avoid affecting the volume and washing capacity of the washing drum 10.

[0073] In this embodiment, combined with Figure 1 and Figure 2 As shown, two negative pressure generating devices 30 are provided. In some embodiments, the two negative pressure generating devices 30 are symmetrically arranged on both sides of the rotating shaft, which can better cover all areas inside the washing drum 10, improve airflow uniformity, and achieve the effects of protecting clothes and efficient drying.

[0074] In some preferred embodiments, at least two of the negative pressure generating devices 30 are connected to the washing drum 10 at different heights in the vertical direction; further, each of the negative pressure generating devices 30 is connected to the washing drum 10 at different heights in the vertical direction; for example, during the drying process, negative pressure generating devices 30 at different positions can be activated according to the height of the clothes piled up, so as to achieve efficient and precise drying. Figure 3 As shown, the bottom 11 of the washing drum 10 is provided with several exhaust vents 13. The exhaust vents 13 are at different heights in the vertical direction to connect with different negative pressure generating devices 30. By cooperating with multiple negative pressure generating devices 30 and multiple exhaust vents 13, all-round airflow can be achieved to cover all areas inside the washing drum 10, improve drying efficiency and ensure drying uniformity.

[0075] In some preferred embodiments, at least one of the negative pressure generating devices 30 is connected to the lower part of the bottom 11 of the washing drum 10. Specifically, the negative pressure generating device 30 is connected to the washing drum 10 at a position closer to the position where the clothes are piled up. When the negative pressure generating device 30 is activated, the airflow can penetrate the layer of clothes piled up at the bottom of the washing drum 10 more evenly, so as to accelerate the diffusion of moisture between the clothing fibers and improve the drying efficiency.

[0076] In some preferred embodiments, combined with Figures 1-4 As shown, the negative pressure generating device 30 includes a fan 31 and an exhaust duct 32; wherein, the exhaust duct 32 is fixed to the bottom 11 of the washing tub 10 and communicates with the washing tub 10, and the fan 31 is installed at one end of the exhaust duct 32. The fan 31 installed at one end of the exhaust duct 32 can generate a strong unidirectional suction force, avoiding interference from multiple duct intersections or reverse flow, resulting in lower airflow path resistance and effectively accelerating moisture evaporation.

[0077] Furthermore, the bottom 11 of the washing tub 10 is provided with an exhaust port 13, and the exhaust duct 32 is provided with an air inlet 321 that matches the shape of the exhaust port 13. When the air inlet 321 is connected to the exhaust port 13, the exhaust duct 32 is connected to the internal environment of the washing tub 10.

[0078] When the drying process is executed, combined with Figure 1 As shown in the drying airflow direction, the fan 31 is started to draw air from the washing drum 10. After a negative pressure environment is formed inside the washing drum 10, the outside air enters the drying tunnel assembly 20 and is heated to form hot air, which then enters the washing drum 10 to dry the clothes. The hot and humid air is drawn by the fan 31 and passes through the exhaust port 13 and the air outlet in sequence into the exhaust duct 32, and is finally output to the outside of the clothing care device 1.

[0079] Furthermore, an air damper is provided between the exhaust duct 32 and the washing drum 10; specifically, an air damper is provided between the exhaust port 13 and the air inlet 321 to open or close the airflow channel. That is, in some preferred embodiments, the drying mode can be adjusted or optimized by adjusting the number of exhaust ports 13 during the drying process to meet different drying needs.

[0080] Furthermore, the fan 31 is located at the highest point of the exhaust duct 32 to prevent water from entering or splashing into the fan 31 and causing damage to the fan 31.

[0081] To further prevent foam from entering the exhaust duct 32 and causing overflow during the washing process, in some preferred embodiments, the height of the connection between the negative pressure generating device 30 and the washing tub 10 is less than or equal to the washing water level of the washing tub 10; specifically, the height of the exhaust vent 13 is less than or equal to the washing water level of the washing tub 10, that is, during the washing process, the washing water seals the exhaust vent 13, effectively preventing foam from entering the exhaust duct 32.

[0082] Furthermore, a sealing structure is provided between the exhaust port 13 and the exhaust duct 32; in this embodiment, a sealing ring 33 is provided between the exhaust port 13 and the air inlet 321 to achieve a sealing effect.

[0083] In some embodiments, a filter structure is provided between the exhaust port 13 and the exhaust duct 32 to effectively intercept lint; further, the filter structure is a filter screen, which is detachably installed in front of the fan 31, and is low in cost, simple in structure, and easy to disassemble and clean.

[0084] In some embodiments, such as Figure 2 As shown, the drying tunnel assembly 20 is located at the top of the washing drum 10, effectively utilizing the top space, optimizing the internal structure of the garment care device 1, and contributing to the compactness of the structure; and the drying tunnel assembly 20 is connected to the upper front end of the washing drum 10, and cooperates with the negative pressure generating device 30 to form an airflow path from top to bottom and from front to back inside the washing drum 10, thereby optimizing the drying effect.

[0085] Furthermore, such as Figure 5 As shown, the drying tunnel assembly 20 includes an air inlet duct 21 and an air inlet heating element 22; the air inlet duct 21 is fixedly installed with the washing drum 10, and the air inlet heating element 22 is disposed in the air inlet duct 21.

[0086] Furthermore, such as Figure 6 As shown, it also includes a heating element 40, which is installed at the bottom of the washing drum 10 to heat the air together with the air inlet heating element 22. During the drying program, the heating element 40 and the air inlet heating element 22 are controlled to work simultaneously, improving heating efficiency and making the air heating more uniform, thereby improving drying efficiency.

[0087] Example 2

[0088] This utility model embodiment also provides a garment care method using a garment care device, combined with Figure 7 As shown, the garment care device described in Example 1 is controlled to perform the following steps:

[0089] S1. When the garment care device enters the drying stage, the distribution of garments inside the washing drum is acquired; wherein, the garment distribution includes at least the weight of the garments, the weight distribution of the garments, and the height of the garment pile; specifically, when a drying command is received, the drying tunnel assembly and the negative pressure generating device are controlled to start to enter the drying stage. At this time, the washing drum is in a negative pressure state under the action of the negative pressure generating device, and the external air is heated by the drying tunnel assembly and enters the washing drum to form a drying airflow, thereby drying the garments inside the washing drum; in some optional embodiments, the garment distribution data inside the washing drum can be collected by an infrared sensor or an image sensor; furthermore, the weight and weight distribution information of the garments can be obtained by combining a weight sensor, thereby assessing the degree of garment pile-up in each area inside the washing drum.

[0090] S2. Control the working mode of the negative pressure generating device according to the distribution of the clothing; wherein, the working mode includes the number of operations, the operating power, and the operating cycle.

[0091] In some implementations, combined Figure 8 As shown, the steps for obtaining the distribution of clothes inside the washing drum include:

[0092] S111. Obtain the weight and / or weight distribution of the clothes in the washing drum; in some embodiments, the weight of the clothes can be obtained directly by a weight sensor; in other embodiments, the weight of the clothes can also be manually input by the user, for example, the user can directly input the estimated weight of the clothes, or input the type of clothes and the number of clothes to match the weight range of the clothes.

[0093] S112. Determine the distribution of the clothing based on the weight and / or weight distribution of the clothing; for example, the weight distribution of the clothing can be used to determine whether the clothing in the washing drum is concentrated on one side, evenly dispersed, or locally piled up.

[0094] In some alternative implementations, combined with Figure 9 As shown, the distribution of clothing includes the weight of the clothing, and the steps for controlling the operating mode of the negative pressure generating device based on the distribution of clothing include:

[0095] S211. Match the weight of the clothes with a preset weight value; wherein, each preset weight value matches a corresponding preset working mode; wherein, the weight of the clothes is the total weight of all clothes in the washing drum.

[0096] S212. If the weight of the clothing matches a preset weight value, then obtain the preset working mode corresponding to the preset weight value as the working mode.

[0097] For example, based on preset weight values, such as 1-3kg for light load, 3-5kg for medium load, and 5-8kg for heavy load, the corresponding working mode can be matched; when it is judged to be light load, control 2 negative pressure generating devices to operate at 50%-60% power and set to continuous airflow; when it is judged to be medium load, control 3 negative pressure generating devices to operate at 70%-80% power and set to intermittent airflow; when it is judged to be heavy load, control 4 negative pressure generating devices to operate at 90%-100% power and set to pulse airflow, such as alternating between strong wind for 20 seconds and weak wind for 40 seconds.

[0098] In some alternative embodiments, the clothing distribution includes clothing weight distribution, combined with... Figure 10 As shown, the steps for controlling the operating mode of the negative pressure generating device according to the distribution of clothing include:

[0099] S221. Determine whether there is local accumulation of clothing based on the weight distribution of the clothing. In some embodiments, multiple weight sensors can be installed in the washing drum. For example, the washing drum can be divided into at least three detection areas, and the weight data of clothing in each detection area can be collected to compare the weight ratio of each detection area. For example, if the weight ratio of a certain detection area is greater than or equal to 30%, it is determined that there is local accumulation of clothing in that detection area.

[0100] S222. If present, turn off the negative pressure generating device corresponding to the local accumulation of clothes, and control the adjacent negative pressure generating device to adjust its working mode to compensate for airflow. Specifically, when there is local accumulation of clothes, turn off the negative pressure generating device in the vertical direction of the local accumulation of clothes, and control the negative pressure generating device in the horizontally adjacent position to increase its power or adjust its operating rhythm to compensate for the drying air volume in the washing drum. For example, its power can be increased to 2-3 times the normal power.

[0101] S223. If not, control the negative pressure generating device to maintain the current working mode.

[0102] This embodiment can effectively prevent the air inlet of the negative pressure generating device from being blocked by clothes while ensuring drying power, thereby preventing the hot and humid air from carrying a large number of water droplets into the exhaust duct in the early stage of the drying process, which could cause short circuits or mold growth.

[0103] In some other implementations, combined with Figure 11 As shown, the steps for obtaining the distribution of clothes inside the washing drum include:

[0104] S121. Acquire image information inside the washing drum; in some embodiments, image information inside the washing drum can be acquired by an infrared sensor or an image sensor.

[0105] S122. Determine the distribution of clothing based on the image information; specifically, the distribution of clothing inside the washing drum can be obtained more accurately based on the image information, such as the location of clothing accumulation inside the washing drum, the degree of tangling of clothing, and whether there is clothing stuck to the wall.

[0106] In some alternative implementations, combined with Figure 12 As shown, the steps for controlling the operating mode of the negative pressure generating device according to the distribution of clothing include:

[0107] S231. Determine whether the connection between the negative pressure generating device and the washing drum is covered by clothing based on the image information;

[0108] S232. If so, control the corresponding negative pressure generating device to shut down, and control the remaining negative pressure generating devices to adjust their working mode for airflow compensation.

[0109] S233. If not, control the negative pressure generating device to maintain the current working mode.

[0110] This implementation method enables more accurate garment status recognition and dynamic air duct control, effectively improving drying efficiency and drying effect.

[0111] Since clothes may shift during the drying process due to factors such as thermal expansion and contraction and airflow, some embodiments also include the following steps:

[0112] Obtain the real-time distribution of the clothing in the washing tub;

[0113] The operating mode of the negative pressure generator is adjusted according to the real-time distribution.

[0114] The system can reanalyze the real-time distribution data of clothes in the washing drum every 3-5 minutes. When a change in the posture of the clothes is detected, the operating mode of each negative pressure generating device is adjusted in a timely manner to ensure that the airflow inside the washing drum is always efficient, thus achieving efficient drying. For example, when clothes that were originally concentrated on the left side of the washing drum are moved due to drying or drum rotation, such as when they move to the bottom of the washing drum, the negative pressure generating device on the left side can be quickly activated, and the negative pressure generating device connected to the bottom can be controlled to reduce its power or be turned off, achieving precise and efficient drying control.

[0115] In some preferred embodiments, the step of:

[0116] After each preset time of operation of the drying duct assembly of the garment care device, the operating power of at least two of the negative pressure generating devices is adjusted or started / stopped to intermittently change the drying airflow inside the washing drum.

[0117] This embodiment adjusts the operating power or starts / stops of some negative pressure generating devices to change the direction and intensity of airflow, creating a varied airflow that acts more evenly on the clothes. This helps to break up tangled and piled-up clothes, allowing them to stretch naturally and improving the drying effect. It can effectively avoid uneven drying caused by unreasonable airflow distribution.

[0118] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
