Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and specifically to a multi-functional body dryer. Background Technology

[0002] With the improvement of living standards, body dryers, as a convenient alternative to towel drying, are increasingly used in home bathrooms, gyms, hotels, and other places. Their core function is to quickly dry the body surface with hot air, improving ease of use and hygiene. However, existing body dryers generally suffer from limited functionality, only providing basic drying and failing to meet users' additional needs for health data monitoring (such as weight monitoring). Furthermore, the drying parameters (temperature, airflow) of existing body dryers are mostly fixed or require manual adjustment, failing to provide personalized adaptation based on individual body weight and shape differences. This results in some users experiencing incomplete drying or discomfort (overheating, excessive airflow) during use.

[0003] In addition, traditional weighing scales are set up separately from dryers, so users need to dry their bodies after showering before measuring their weight. This is cumbersome and can easily cause safety hazards due to slippery floors. If the weighing scale is used directly on a wet and slippery floor, not only will the measurement accuracy be affected, but there is also a risk of slipping. Summary of the Invention

[0004] To address the aforementioned technical problems, enhance user experience, efficiently and quickly dry the body surface while safely measuring the user's weight data and accurately obtaining changes in their weight, this invention provides a multifunctional body dryer.

[0005] The technical solution adopted is as follows:

[0006] A multi-functional body dryer includes a housing and a control device. The housing contains a chamber with an air supply channel, a fan, and a heating element. The heating element is located within the air supply channel. The control device is electrically connected to the fan and the heating element. A standing area is located on the upper surface of the housing, with an air outlet connected to an air outlet hole in the air supply channel. A weighing device is located on the lower surface of the housing, comprising a weighing sensor, a weighing sensor bracket, and a top block. The top block is movably mounted on a through hole on the lower surface of the housing. The weighing sensor is fixed to the weighing sensor bracket and electrically connected to the control device. The weighing sensor bracket is fixed within the chamber. When the housing is under load, the upper end of the top block abuts against the weighing sensor. The control device receives the weighing signal and controls the airflow and temperature.

[0007] Preferably, the lower end face of the housing is provided with four through holes arranged in a rectangular array, and the weighing devices are respectively installed in the four through holes, and the signal output terminals of each weighing device are electrically connected to the control device.

[0008] More preferably, the control device includes a main control chip, a drive unit electrically connected to the main control chip, a data storage unit, and a communication unit. The drive unit is electrically connected to the fan and the heating component. The main control chip has a built-in weight association algorithm that can match preset drying parameters based on real-time weight data. The communication unit wirelessly transmits the obtained data to a mobile terminal.

[0009] Furthermore, the control device has a built-in data calibration unit for error correction and mean calculation of four sets of weighing data, with a weighing accuracy of ≤ ±0.1 kg.

[0010] Furthermore, the standing area on the housing is provided with multiple upper openings, each of which is provided with a spring and an electrode plate. The spring is located at the upper opening, with its upper end extending out of the upper opening and pressing against the lower end face of the electrode plate. The spring is electrically connected to the control device to measure the impedance signal during current conduction. The main control chip has a built-in body fat percentage algorithm, which combines the measured weight, impedance value, and input height, age, and gender data to obtain body fat percentage data.

[0011] More preferably, the standing area on the housing has four upper openings arranged in a rectangular array.

[0012] Furthermore, the housing is also equipped with a temperature sensor for detecting the outlet air temperature. The temperature sensor is connected to the control device and controls the heating power of the heating component based on the set outlet air temperature and the real-time monitored outlet air temperature.

[0013] Furthermore, the housing is also equipped with a human body sensor, which is electrically connected to the temperature controller in the control device, for detecting whether someone is standing in the standing area of ​​the housing, and controlling the air volume and air temperature of the air outlet according to the detected human body weight.

[0014] Preferably, the air supply channel includes a cold air channel and a hot air channel, the heating component is installed in the hot air channel, the fan is located at the converging air inlet of the cold air channel and the hot air channel, and a cold and heat conversion regulating plate is provided at the converging air inlet, the operating end of the cold and heat conversion regulating plate extends out of the outer side of the housing.

[0015] More preferably, the lower end of the top block is also provided with an anti-slip silicone pad.

[0016] The technical solution of the present invention has the following advantages:

[0017] A. The dryer and weighing device provided by this invention are integrated into one structure. After showering, the user can stand directly on the standing area on the dryer housing to simultaneously monitor weight and dry the body. There is no need to use an additional scale, avoiding the cumbersome and safety hazards of wet body measurement and improving ease of use.

[0018] B. This invention personalizes drying parameters for greater comfort. The adaptive adjustment algorithm based on weight data can match the optimal drying parameters according to the user's body shape differences, avoiding incomplete drying or discomfort caused by fixed parameters. It also supports manual switching between multiple modes to meet the needs of different users.

[0019] C. This invention offers high weighing accuracy and data traceability: It employs an array of four weighing sensors and data calibration technology, achieving a weighing accuracy of ≤±0.1kg.

[0020] D. This invention offers comprehensive safety protection for greater peace of mind: It integrates multiple safety designs such as anti-slip pedals, overheat protection, and human body induction delayed shutdown, making it suitable for use in humid bathroom environments and eliminating problems such as burns, slips, and energy waste.

[0043] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figures 1 to 5As shown, this invention provides a multifunctional body dryer, including a housing 1 and a control device 2. The housing 1 includes an upper shell 11 and a lower shell 12, which are connected by a snap-fit ​​connection. A chamber a is provided inside the housing 1, containing an air supply channel 3, a fan 4, and a heating element 5. An air inlet 20 is also provided on the outer side of the housing 1, and an air inlet cover 10 is installed at the air inlet 20. The fan 4 is a high-speed fan. The heating element 5 is disposed in the air supply channel 3. The control device 2 is electrically connected to the fan 4 and the heating element 5, and can regulate the fan speed and the heating power of the heating element 5. A standing area b is provided on the upper surface of the housing 1, and an air outlet b1 is provided in the standing area b. The air outlet b1 is connected to the air outlet 3a on the air supply channel 3, and the air sprayed from the air outlet b1 can dry the body. A weighing device 6 is also provided on the lower surface of the housing 1, which can be combined with… Figure 4 and Figure 5 As shown, the system specifically includes a weighing sensor 61, a weighing sensor bracket 62, and a top block 63. The top block 63 is mounted vertically on the through hole 1a on the lower end face of the housing 1. The weighing sensor 61 is fixed on the weighing sensor bracket 62 and electrically connected to the control device 2. The weighing sensor bracket 62 is fixed in the chamber a. When someone stands in the standing area of ​​the housing 1, the lower end of the top block 63 is supported by the ground, and the housing 1 descends as a whole, causing the upper end of the top block 63 to abut against the lower end face of the weighing sensor 61. The control device 1 receives the weighing signal and displays the weight value.

[0045] The preferred top block 63 of this invention is cantilevered and can move up and down. It has sufficient vertical movement space with the through hole 1a on the lower shell 12. When a person stands in the standing area, the entire shell 1 is subjected to downward gravity, and the top block 63 is supported by the upward force of the ground. The top block 63 is in contact with the weighing sensor 61. At this time, the weight of the person is concentrated here. The weighing sensor transmits the signal to the display control panel, which can be clearly seen by the user.

[0046] To better adapt to use in humid environments, this invention includes an anti-slip silicone pad 64, which is attached to the top block 63 to provide anti-slip protection. The top block 63 is then fitted onto the lower shell 12, and the weighing sensor 61 is clipped onto the weighing sensor bracket 62. The weighing sensor bracket 62 is then secured to the lower shell 12 with screws.

[0047] Preferably, the present invention has four through holes 1a arranged in a rectangular array on the lower end face of the housing 1. Weighing devices 6 are respectively installed in the four through holes 1a. The signal output terminals of each high-precision weighing device 6 are electrically connected to the control device 2, thereby improving the accuracy of the measured weight. The control device 2 further incorporates a data calibration unit for error correction and mean calculation of the four sets of weighing data, achieving a weighing accuracy of ≤±0.1kg.

[0048] The control device 2 includes a main control chip, a drive unit electrically connected to the main control chip, a data storage unit, a communication unit, and a control panel. The control panel allows selection of drying modes and setting of relevant drying parameters. The drive unit is electrically connected to the fan and heating components. The main control chip has a built-in weight correlation algorithm that matches preset drying parameters based on real-time weight data. The communication unit wirelessly transmits the obtained data to a mobile terminal, and also supports wireless connection with the mobile terminal via Bluetooth communication unit to achieve data synchronization and remote parameter setting.

[0049] This invention offers the advantages of personalized drying parameters and enhanced user comfort. Its adaptive adjustment algorithm, based on weight data, matches optimal drying parameters to individual user body types, avoiding incomplete drying or discomfort caused by fixed parameters. It also supports manual switching between multiple modes to meet diverse user needs. The data storage unit can record weight data for the past 90 days, allowing users to view weight change curves on a display screen or mobile device, thus aiding in health management.

[0050] Because the weighing device is electrically connected to the control device, the control device can automatically control the start / stop or operating mode of the fan and heating components based on the signal changes detected by the weighing device.

[0051] like Figure 7 As shown, the air supply channels include a cold air channel 31 and a hot air channel 32. The heating element is preferably a circular heating wire heating element, which is installed in the hot air channel 32. The fan 4 is located at the converging air inlet c of the cold air channel 31 and the hot air channel 32, and a heat exchange regulating plate 9 is provided at the converging air inlet c. The operating end of the heat exchange regulating plate 9 extends out of the outer side of the housing 1, and its structure is visible. Figure 7 As shown, the heating / cooling conversion adjustment plate 9 is integrated from multiple structures. The air supply channel 3 includes an upper and lower shell, with the hot and cold air channels forming a "3" shape. The upper shell 11 has three air outlets b1, with the central outlet being the cold air outlet and the two side outlets being the hot air outlets. The small size of the air outlets allows for air pressure, enabling the air to travel further. When the fan is working, external air is drawn into the chamber through the air inlet. After being processed by the fan, it blows out high-speed air with a certain air pressure, quickly drying water droplets on the body surface. By rotating the heating / cooling conversion adjustment plate 9, the system switches to the hot air channel and simultaneously closes the cold air channel. The heating element activates, allowing the airflow to pass through the hot air channel and be heated before being blown out as warm air for drying. Adjustments can be made according to actual needs.

[0052] Ideally, the airflow path within the air supply duct should be close to the size of the drive motor; if the size is too large or too small, it will affect the overall performance of the machine.

[0053] As a further preferred embodiment of the present invention, a temperature sensor (not shown in the figure) for detecting the outlet air temperature can also be provided on the housing 1. The temperature sensor is connected to the control device 2. The control device 2 controls the heating power of the heating component 5 according to the set outlet air temperature and the real-time monitored outlet air temperature, thereby realizing the control of the outlet air temperature and achieving safer use.

[0054] In addition, the housing 1 is equipped with a human body sensor, which is electrically connected to the temperature controller in the control device 2. It is used to detect whether someone is standing in the standing area of ​​the housing, and to control the air volume and air temperature of the air outlet according to the detected human body weight or body fat percentage.

[0055] As a further preferred embodiment of the present invention, such as Figures 6 to 7 As shown, multiple upper openings b2 are provided in the standing area b on the upper shell 11. Each upper opening b2 is also provided with a spring 7 and an electrode plate 8. The spring 7 is located at the upper opening b2, with its upper end extending out of the upper opening b2 and pressing against the lower end face of the electrode plate 8. The spring 7 is electrically connected to the control device 2 to measure the impedance signal during current conduction. The main control chip in the control device has a built-in body fat percentage algorithm, which combines the measured weight, impedance value, and input height, age, and gender data to obtain body fat percentage data. Preferably, four upper openings b2 arranged in a rectangular array are provided in the standing area b on the upper shell 11.

[0056] Based on the weighing device installed on the shell, electrode plates 8 and springs 7 are installed on the upper shell 11. The core of electrode plate 8 is based on bioelectrical impedance analysis. When a person stands barefoot on the electrode plate 8 on the shell 1, it emits a weak and safe alternating current to the body, forming a current closed loop. Because non-fat tissues such as muscle have high water content and low resistance, while fat tissue has low water content and high resistance, the electrode plate captures the impedance signal during current conduction. Finally, by combining this signal with user-inputted data such as height and age, a built-in algorithm can calculate body composition data such as body fat percentage and muscle mass.

[0057] In summary, the dryer of this invention has a compact overall structure and a high degree of functional integration. It not only solves the problem of the single function of existing dryers, but also improves the user experience through personalized adaptation and safety protection design, and has broad market application prospects.

[0058] Any aspects not covered in this invention are applicable to existing technologies.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
