Description

Technical Field

[0001] This utility model relates to a clothes dryer. Background Technology

[0002] Existing dryers primarily manage the drying process through timer control. Once the user sets the drying time, the dryer operates according to the preset program and stops drying when the preset time is reached. This drying method has the following drawbacks:

[0003] Relying solely on a preset drying time to determine when drying is complete ignores differences in the initial moisture content of the garments and the type of fabric, which can easily lead to over-drying or under-drying. Over-drying not only wastes energy but also damages the fabric fibers, while under-drying leaves the garments feeling damp after removal from the dryer, affecting wearing comfort and potentially causing bacterial growth. Utility Model Content

[0004] The purpose of this invention is to provide a dryer that avoids over-drying or under-drying.

[0005] The purpose of this utility model is achieved as follows:

[0006] A clothes dryer includes a hook device, a housing, a drying device, a force sensor, a control panel, and a clothes hanging rod device. The housing has an opening communicating with the inner cavity of the housing, and the drying device is disposed in the inner cavity of the housing.

[0007] The hook device is movably connected to the housing, and the clothes rod device is located at the opening, with the clothes rod device and the housing being movably connected;

[0008] The force sensor is installed inside the housing. The force sensor and the drying device are electrically connected to the control panel. The hook device or clothes hanging rod device contacts the force sensor. The force on the hook device or the clothes hanging rod device is transmitted to the control panel through the force sensor.

[0009] By installing a force sensor inside the housing, this invention can monitor the weight changes of clothing in real time and transmit the information to the control panel for analysis. Compared with traditional dryers that rely solely on time, this invention can dynamically determine the actual drying status of clothing based on weight changes, thereby adjusting or terminating the drying program. This effectively avoids under-drying or over-drying of clothing, ensuring thorough drying while maximizing fiber protection from high-temperature damage.

[0010] The objective of this utility model can also be achieved by the following technical measures:

[0011] Furthermore, the top of the housing has a slot, the hook device includes a hook, a rotating shaft and a base, the side wall of the base has a notch, the base is fixed inside the housing and located at the bottom of the slot, and the notch and the inner wall of the housing form a shaft hole;

[0012] The tail of the hook passes through the slot and is placed inside the base. The rotating shaft passes through the tail of the hook, and the end of the rotating shaft extends into the corresponding shaft hole, so as to realize the rotatable connection between the hook and the housing. The hook rotates into or out of the slot.

[0013] The force sensor is installed inside the shaft hole and above the rotating shaft, and the force on the hook is transmitted to the force sensor.

[0014] By opening a slot at the top of the housing and adopting a movable hook structure consisting of a base, shaft hole, and rotating shaft, a reliable rotatable connection between the hook and the housing is achieved. When the hook bears the weight of the clothes, the force at the tail of the hook can be directly transmitted to the force sensor set in the shaft hole through the rotating shaft, ensuring the simplicity and accuracy of the force transmission path. This enables high-precision monitoring of the force change on the hook, providing a stable and reliable data source for detecting the weight of clothes during the drying process.

[0015] Furthermore, the clothes rack device includes a clothes rack, a bolt, and a base. The housing is provided with a lower receiving groove, the force sensor is placed in the lower receiving groove, the base is placed at the bottom of the lower receiving groove, and the bolt passes through the force sensor and the lower receiving groove to connect to the base.

[0016] The ends of the clothes rack are connected to corresponding bases, so that the clothes rack can be rotated and set at the opening. The force on the clothes rack is transmitted to the force sensor.

[0017] The clothes hanging rod device uses a combination of bolts, a base, a force sensor, and a lower receiving groove to directly transmit the force on the clothes hanging rod to the force sensor, thereby achieving accurate measurement of the weight the clothes hanging rod can bear. Furthermore, the clothes hanging rod can rotate around the base, making it convenient for users to hang and retrieve clothes. This design ensures both the sensitivity and repeatability of clothing weight detection and ease of use, enabling the entire machine to maintain accurate weight feedback under various types of clothing and different hanging methods.

[0018] Furthermore, it also includes a humidity sensor, which is disposed inside the housing and electrically connected to the control panel.

[0019] The humidity sensor can monitor the humidity of the hot and humid air in the dryer in real time and directly. This arrangement ensures that the humidity sensor responds sensitively to humid air and avoids the sensor being directly exposed to high temperature and high humidity environment, which improves the service life and detection accuracy of the sensor, thus providing reliable humidity data for intelligent drying control.

[0020] Furthermore, it also includes a clothes drying bag, which is detachably / fixedly mounted on the housing. The opening is connected to the clothes drying bag. The housing and / or the clothes drying bag are equipped with a humidity sensor, which is electrically connected to the control panel.

[0021] The combination of the detachable drying bag, hook device, and hanging rod device provided by this invention not only allows users to freely hang clothes according to the quantity and type of clothing, but also facilitates cleaning and maintenance.

[0022] By incorporating humidity and force sensors, this invention can monitor changes in the moisture content and weight of clothing in real time and transmit this information to the control panel for comprehensive analysis. Compared to traditional dryers that rely solely on time, this invention can dynamically adjust or terminate the drying process based on the actual drying status of the clothing, effectively preventing under-drying or over-drying. This ensures thorough drying of the clothing while maximizing the protection of fibers from high-temperature damage.

[0023] The beneficial effects of this utility model are as follows:

[0024] This invention, by setting a force sensor inside the housing, can monitor the weight changes of clothing in real time and transmit the information to the control panel for analysis. Compared with traditional dryers that rely solely on time, this invention can know the actual drying status of clothing based on weight changes, thereby adjusting or terminating the drying program, effectively avoiding under-drying or over-drying of clothing, ensuring thorough drying of clothing, and protecting fibers from high-temperature damage to the greatest extent.

[0025] This invention, by incorporating humidity and force sensors, can monitor changes in the moisture content and weight of clothing in real time and transmit this information to the control panel for comprehensive analysis. Compared to traditional dryers that rely solely on time, this invention can determine the actual drying status of clothing based on changes in moisture content and weight, thereby dynamically adjusting or terminating the drying process. This effectively avoids under-drying or over-drying, ensuring thorough drying while maximizing fiber protection from high-temperature damage. Attached Figure Description

[0039] The force sensor 4 is installed inside the housing 2. The force sensor 4 and the drying device 3 are electrically connected to the control panel 5 respectively. The hook device 1 contacts the force sensor 4. The force on the hook device 1 or the force on the clothes hanging rod device 6 is transmitted to the control panel 5 through the force sensor 4.

[0040] The clothes drying bag 8 is detachably or fixedly mounted on the housing 2, and the opening 21 is connected to the clothes drying bag 8;

The rotating shaft 12 passes through the tail of the hook 11 and the end of the rotating shaft 12 extends into the corresponding shaft hole 132, so as to realize the rotatable connection between the hook 11 and the housing 2. The hook 11 rotates into or out of the slot 28.

[0044] The force sensor 4 is disposed in the shaft hole 132 and located above the rotating shaft 12, and the force on the hook 11 is transmitted to the force sensor 4.

[0045] Furthermore, the clothes rack device 6 includes a clothes rack 61, a bolt 62 and a base 63. The housing 2 is provided with a lower receiving groove 22. The base 63 is placed at the bottom of the lower receiving groove 22. The bolt 62 passes through the lower receiving groove 22 and connects to the base 63.

[0046] The ends of the clothes hanging rod 61 are respectively connected to the corresponding seats 63, so that the clothes hanging rod 61 is rotatably set at the opening 21.

[0047] Furthermore, it also includes a bottom cover 9, which is rotatably mounted on the housing 2, and the bottom cover 9 rotates to open or close the opening 21.

[0048] Furthermore, the housing 2 includes an outer shell 23 and an inner shell 24. The inner shell 24 is provided with a groove 25 for clamping the dryer bag 8. Clamping parts 251 are provided at intervals in the groove 25. The inner shell 24 is provided with an installation cavity 241 that runs vertically through the interior and exterior.

[0049] The inner shell 24 is fixed to the inner cavity of the outer shell 23, and an air channel 26 is formed between the outer shell 23 and the inner shell 24. The air channel 26 is connected to the mounting cavity 241, and the outer shell 23 has an air inlet connected to the air channel 26.

[0050] The fan 31 and the heating element 32 are disposed inside the mounting cavity 241, and the control panel 5 is disposed on the side wall of the outer shell 23.

[0051] The drying bag 8 has an upper air vent 81 at the top and a clothing inlet / outlet 82 on the side. The top of the drying bag 8 forms a ring-shaped locking part around the upper opening 21. The ring-shaped locking part is inserted into the groove 25, and the locking part 251 and the ring-shaped locking part are locked together. The upper air vent 81 is connected to the opening 21.

[0052] Furthermore, the top of the inner shell 24 has an upper receiving groove 27, the bottom of the inner shell 24 has a lower receiving groove 22, the bottom of the upper receiving groove 27 has air holes 271 spaced apart, and the humidity sensor 7 is disposed in the upper receiving groove 27.

[0053] Working principle:

[0054] A force sensor 4 is integrated above the pivot 12 of the hook 11. When the housing 2 bears its own weight through the hook 11, the clothes are hung on the clothes rod 61. The weight of the clothes is transmitted to the force sensor 4 along the clothes rod 51 → hook 11 → pivot 12. The strain element in the force sensor 4 undergoes a slight deformation when subjected to force, which changes the balance of the bridge circuit and outputs a voltage signal proportional to the force. The control panel 5 calculates the magnitude of the force based on this signal. Since this force is the weight of the clothes in the Earth's gravitational field (F=mg), the force measured on the hook 11 represents the weight of the clothes. The force sensor 4 transmits the force change to the control panel 5 every preset time. The control panel 5 calculates the weight change of the clothes within the preset time.

[0055] Humidity sensor 7 is installed in the upper receiving groove 27 above the inner shell 24 and communicates with the inner cavity of the clothes drying bag 8. When hot air flows through the clothes drying bag 8 and takes away the moisture in the clothes, the humidity of the air inside the clothes drying bag 8 changes accordingly. The sensitive element (such as a capacitive or resistive humidity chip) in humidity sensor 7 responds to the water vapor content in the surrounding air and outputs an electrical signal that is proportional to the relative humidity. The control panel 5 judges the change in humidity of the air inside the clothes drying bag 8 based on this signal, thereby indirectly reflecting the moisture content on the surface and inside of the clothes. Humidity sensor 7 transmits the humidity information to control panel 5, and control panel 5 records it as the humidity of the clothes.

[0056] After the outside cold air is drawn in through the air inlet on the side wall of the outer shell 23, it first enters the air passage 26 between the outer shell 23 and the inner shell 24. When the fan 31 is started, it draws in the cold air in the air passage 26 and pushes it through the heating tube 32 that has been energized and heated in the mounting cavity 241, so that it can quickly absorb heat and heat up to form hot air. The hot air then flows along the opening 21 and through the upper air outlet 81 at the top of the drying bag 8 into the drying bag 8, and evenly acts on the wet clothes hanging on the clothes rack 61, thereby achieving efficient drying.

[0057] Combination Figure 9 As shown, in other embodiments, the clothes drying bag 8 is also provided with a humidity sensor 7.

[0058] Example 2, combined with Figures 6 to 8 As shown, a clothes dryer includes a hook 11 device 1, a housing 2, a drying device 3, a force sensor 4, a control panel 5, a clothes hanging rod device 6, a humidity sensor 7, and a drying bag 8.

[0073] Working principle:

[0074] When clothes are hung on the clothes rack 61, their weight is transmitted to the force sensor 4 along the clothes rack 61 → base 63 → bolt 62. The strain element in the force sensor 4 undergoes a slight deformation when subjected to force, which changes the balance of the bridge circuit and outputs a voltage signal proportional to the force. The control panel 5 calculates the magnitude of the force based on this signal. Since this force is the weight of the clothes in the gravitational field (F=mg), the force on the clothes rack is equal to the weight of the clothes. The force sensor 4 transmits the force change to the control panel 5 every preset time interval, and the control panel 5 calculates the weight change of the clothes within the preset time interval.

[0075] Humidity sensor 7 is installed in the upper receiving groove 27 above the inner shell 24 and communicates with the inner cavity of the clothes drying bag 8. When hot air flows through the clothes drying bag 8 and takes away the moisture in the clothes, the humidity of the air inside the clothes drying bag 8 changes accordingly. The sensitive element in humidity sensor 7 (such as a capacitive or resistive humidity chip) responds to the water vapor content in the surrounding air and outputs an electrical signal that is proportional to the relative humidity. The control panel 5 judges the change in humidity of the air inside the clothes drying bag 8 based on this signal, thereby indirectly reflecting the moisture content on the surface and inside of the clothes, which represents the humidity of the clothes. Humidity sensor 7 transmits the humidity information to the control panel 5, and the control panel 5 records it as the humidity of the clothes.

[0076] After the outside cold air is drawn in through the air inlet on the side wall of the outer shell 23, it first enters the air passage 26 between the outer shell 23 and the inner shell 24. When the fan 31 is started, it draws in the cold air in the air passage 26 and pushes it through the heating tube 32 that has been energized and heated in the mounting cavity 241, so that it can quickly absorb heat and heat up to form hot air. The hot air then flows along the opening 21 and through the upper air outlet 81 at the top of the drying bag 8 into the drying bag 8, and evenly acts on the wet clothes hanging on the clothes rack 61, thereby achieving efficient drying.

[0077] Combination Figure 9 As shown, in other embodiments, the clothes drying bag 8 is also provided with a humidity sensor 7.

[0078] Combination Figure 10 The intelligent clothes drying control method used in Examples 1, 2, and other examples includes the following steps:

[0079] Step 1: The user hangs the clothes on the clothes rack device 6. The user starts the intelligent drying mode through the control panel 5. The drying device 3, force sensor 4 and humidity sensor 7 are activated. The drying device 3 generates hot air and blows it through the opening 21 to the drying bag 8 to dry the clothes.

[0080] Step 2: When the force sensor 4 reaches the preset time, the force sensor 4 transmits the force situation at the preset time to the control panel 5. The control panel 5 calculates the difference between the force at the previous preset time and the force at the current preset time, thereby obtaining the weight change value of the clothing. At the same time, the control panel 5 compares the weight change value with the preset change value.

[0081] The humidity sensor 7 transmits the humidity information to the control panel 5, which records the humidity of the clothing and compares it with the preset humidity.

[0082] Step 3: If the weight change value is greater than the preset change value, proceed to Step 2;

[0083] If the humidity of the clothing is higher than the preset humidity, proceed to step two;

[0084] When the weight change value is less than or equal to the preset change value and the clothing humidity is less than or equal to the preset humidity, the heating element of the drying device stops working. At the same time, the fan 31 of the drying device 3 continues to work to generate cold air. The cold air is blown through the opening 21 to the drying bag 8 to cool the clothes until the preset cooling time ends.

[0085] Step 4: After the preset cooling time is completed, the dryer is turned off, and the power to the drying device 3, force sensor 4 and humidity sensor 7 is cut off.

[0086] Furthermore, the preset time is 10 minutes, the preset change value is 1 g, the preset humidity is 10%RH, and the preset cooling time is 15 seconds.

[0087] For example: If the dryer is started at 12:00, the control panel will know that at 12:00, the force sensor 4 is subjected to force A, which is the weight of the clothes. After 10 minutes, the control panel will know that at 12:10, the force sensor 4 is subjected to force B, which is the weight of the clothes. BA = weight change value.

[0088] Furthermore, it also includes a buzzer and a network module, which are disposed inside the housing 2. The buzzer and the network module are electrically connected to the control panel 5 respectively. After the dryer reaches the preset cooling time, the control panel 5 activates the buzzer, which emits a prompt sound. At the same time, the control panel 5 activates the network module, and the network sends a drying end message to the user's mobile phone.
