Description

Technical Field

[0001] This utility model belongs to the technical field of drying and heating equipment, specifically a control system for a towel dryer that can store towels. Background Technology

[0002] In winter, washing up is necessary before going out early in the morning. To reduce skin irritation, towels are usually soaked in hot water before use. However, this involves many steps, such as fetching and boiling water, which is too difficult in winter. Even after going out, the process of fetching and boiling water again is inconvenient. Furthermore, towels are difficult to dry in winter, and damp towels are prone to bacterial growth and mold if left damp for extended periods. Therefore, towel racks with heating functions exist on the market, such as the published patent document "CN218247033U, A Smart Electric Heated Towel Rack Control System," which can both dry the towels and achieve relatively energy-saving effects. However, the above patent solution continuously heats the towels. Since hot towels are often only needed for specific periods at home, continuously maintaining the towel temperature consumes a lot of electricity. Moreover, current towel dryers are quite large and take up a lot of space. Utility Model Content

[0003] The purpose of this invention is to provide a control system for a retractable towel dryer to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A control system for a retractable towel dryer includes a base and an upper frame, as well as several support rods for supporting the upper frame. A soft fabric is provided between the base and the upper frame to form a placement space. A wiring channel is provided on the side of the soft fabric near the placement space, through which wires are threaded. The wires are used to electrically connect a control panel and a controller. The control panel is located on the upper frame, and the controller is mounted on the base. The controller is electrically connected to a heating module and a fan, with the fan facing the placement space from its output end. The upper frame has an opening and is connected to a cover plate, which is used to close the opening. The controller includes a microprocessor, which is electrically connected to a power management module, an adjustment module, and a timer.

[0005] In a further technical solution, the adjustment module includes a comparator and a storage unit that are electrically connected. The comparator is electrically connected to the microprocessor.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please refer to Figure 1-6 ; The drying and heating machine described in this utility model aims to achieve a storage function and has a more user-friendly operation and control system to meet people's daily needs. Specifically, it includes a base 1 and an upper frame 21, as well as several support rods 5 for supporting the upper frame 21. During use, the relative position of the base 1 and the upper frame 21 can be changed by changing the state of the support rods 5, thereby achieving storage and making the whole unit flat and reducing the space occupied. The specific method is described below. In this utility model, the shape and size of the base 1 and the upper frame 21 are not limited. For example, they can be circular, rectangular, etc., or the base 1 can be larger than the upper frame 21, etc. Of course, it is preferred that the base 1 and the upper frame 21 are the same size. The upper and lower sides of the soft fabric 3 are sealed and connected to the outer periphery of the base 1 and the outer periphery of the upper frame 21, respectively. Specifically, they can be glued or fastened by other fasteners. It should be noted that soft fabrics can be made of nylon, polyester, spandex, etc., which are elastic and breathable.

[0022] In this utility model, a control panel 6 is provided in the upper frame 21 for easy user operation, and a controller is installed in the base 1. A wire is needed to connect the control panel 6 and the controller together. However, since the soft fabric 3 cannot be used for wiring, in this embodiment, a wiring channel 31 is formed on the side of the soft fabric 3 near the placement space 4. Specifically, the other side of the fabric can be covered on the soft fabric 3 by sewing or gluing. When the dryer needs to be stored, the soft fabric 3 will also be folded. At this time, the wiring channel 31 and the wire can also be folded, and it will not be visible from the outside, which is very aesthetically pleasing. A heating module and a fan 11 are also installed in the base 1. Both are electrically connected to the controller. The fan 11 faces the placement space 4 with its output end facing the upper frame 21. An opening is formed in the upper frame 21 and is connected to a cover plate 22, which is used to close the opening. During use, the upper frame 21 is lifted and fixed by the support rod 5, so that the upper frame 21 is above the base 1, and together with the soft fabric 3, it is supported to form the placement space 4. The opening can be exposed by lifting the cover plate 22. Then, the user can put the towel into the placement space 4 through the opening and then close the cover plate 22 again to seal it. Finally, the control panel 6 sends a signal to the controller, so that the controller can start the heating module and the fan 11 to output hot airflow in the placement space 4, thereby heating and drying the towel. Because the soft fabric is breathable, under a certain wind pressure, the gas in the placement space 4 can be discharged from the fine pores of the soft fabric. The generated hot airflow evaporates the water in the towel and discharges to the outside through the fine pores of the soft fabric within a sufficiently long drying time. Moreover, the hot airflow also acts on the soft fabric, raising its temperature, so the soft fabric will not be wetted by water vapor and can be kept dry. In addition, the main function of the cover plate is to cover the opening. There is a gap between the cover plate and the edge of the upper frame, and airflow can also be discharged through these gaps, so there is no need to set up a separate exhaust port.

[0023] It should be noted that the towels described in this embodiment are not limited to bath towels, face towels or other knitted products. Of course, since they do not have good drainage, it is not recommended to put in a wet towel that is still dripping water, as this may easily damage the hot air blower 11. Slightly damp towels can still be used.

[0024] Furthermore, referring to Figure 5 The controller includes a microprocessor, which is electrically connected to a power management module, an adjustment module, and a timer. The power management module is used to supply power to the load and adjust the output power according to the signal sent by the microprocessor. The adjustment module and the timer are used to send instructions to the microprocessor to control the fan 11 and the heating module. In one usage method, the running time and the required heating temperature are first set via the control panel 6, which are then converted into electrical signals and input to the microprocessor. The microprocessor rewrites the parameters of the adjustment module and timer one, and then the system is started. At this time, timer one will start timing, and the adjustment module will send the required temperature signal to the microprocessor. After receiving this signal, the microprocessor will send a signal to the power management module, which will adjust the power output according to the signal information, thus controlling the heat output of the heating module to reach the required temperature. When timer one reaches its time limit, it sends a signal to the microprocessor to stop the control system. This method is suitable for situations where the user is away for a short time and will use the towel upon returning. In this case, timer one can be set for a period of several hours. If the user does not return within the specified time, the entire system will stop running to avoid excessive energy waste.

[0025] Another usage method involves first setting the running time and the required heating temperature via control panel 6. This is converted into an electrical signal and input to the microprocessor. The microprocessor then rewrites the parameters of the adjustment module and timer 1, where timer 1 specifies the delay start time. After the system is started, timer 1 begins timing, while the system remains in standby mode. This method is suitable for using a hot towel at a specific time, such as the next morning. In this case, an 8-hour delay start can be set at night. When the timer 1 reaches its set time, it sends a signal to the microprocessor to start the system. The microprocessor receives the required temperature signal from the adjustment module and then sends a signal to the power management module. The power management module adjusts the power output based on the signal information, ultimately controlling the heat output of the heating module to achieve the desired temperature. In this embodiment, the system needs to be manually turned off.

[0026] After use, the towels in the storage space 4 are removed. By changing the relative position of the support rod 5 with the base 1 and the upper frame 21, the upper frame 21 loses its support and moves towards the base 1 to achieve folding. This reduces the height of the dryer, making it smaller and taking up less space, thus making it easier to store and place.

[0027] There are two ways in which the support rod 5 lifts the upper frame 21 in this utility model; Implementation method one, refer to Figure 1 and Figure 2 The two ends of the support rod 5 abut against the base 1 and the upper frame 21 respectively, and are detachably connected. Assuming that the upper frame 21 and the base 1 are both quadrilateral, there are four support rods 5, each located at a corner. In the initial state, the four support rods 5 are separated from the upper frame 21 and the base 1, and the support rods 5 can be placed in any position. Preferably, they can be placed horizontally between the upper frame 21 and the base 1 to avoid loss. The upper frame 21 and the base 1 are stacked, which occupies the least space. When needed, several support rods 5 are taken out and placed at each corner, so that the two ends of the support rods 5 abut against the base 1 and the upper frame 21 respectively, thereby supporting the upper frame 21 to form the placement space 4. Preferably, the length of the support rod 5 is slightly greater than the height of the soft fabric 3. The soft fabric 3 has some elasticity. The soft fabric 3 closes and applies a pulling force to the upper frame 21 and the base 1, making the overall support structure more stable. The support method in this embodiment does not require additional structure, making the whole more concise and the operation very convenient.

[0028] Implementation method two, refer to Figure 3 and Figure 4The support rod 5 is a folding rod, with one end rotatably connected to the upper frame 21 and the other end rotatably connected to the base 1. Assuming that both the upper frame 21 and the base 1 are quadrilaterals, there are four corresponding support rods 5, each located at a corner. Initially, the folding rods are folded, causing the upper frame 21 and the base 1 to be close to each other and stacked, thus minimizing space occupation. When needed, the folding rods are pushed straight from the folded state to a vertical state, with both ends rotating relative to the upper frame 21 and the base 1 respectively, and finally perpendicular, supporting the upper frame 21 to form the placement space 4. Preferably, the length of the support rod 5 is slightly greater than the height of the soft fabric 3. The soft fabric 3 has some elasticity, and the closed soft fabric 3 applies a pulling force to the upper frame 21 and the base 1 to make the overall support structure more stable. In this embodiment, the support rod 5 remains connected to the upper frame 21 and the base 1, which can prevent loss or improper fixing that could lead to loose support.

[0029] Furthermore, the folding rod can be folded in different directions. Preferably, the support rod 5 is placed with the folding direction facing downwards in the space 4 or along the side length, which can reduce space occupation.

[0030] Based on all the above embodiments, the soft fabric 3 is nylon fabric.

[0031] In addition, in this embodiment of the utility model, the support rod 5 is located within the placement space 4, making the overall appearance more aesthetically pleasing.

[0032] The adjustment module is further described in this embodiment of the utility model; Specifically, it includes an electrically connected comparator and a memory. The comparator is electrically connected to the microprocessor. The memory has preset temperature thresholds at various levels, where each temperature threshold refers to an electrical change in the corresponding temperature value. When a temperature value needs to be specified, the corresponding temperature value is input through the control panel 6. In addition to input buttons, the control panel 6 should also have a control circuit board and a control communication chip for communication with the microprocessor. The required temperature value is converted into an electrical signal and input to the microprocessor. The microprocessor resets the value in the comparator. At the same time, the comparator cyclically scans the temperature thresholds at various levels in the memory to match the value in the comparator at this time. After finding a matching value, it is sent to the microprocessor to proceed to the next step of the program. By constantly cyclically scanning, values ​​can be quickly assigned, resulting in a faster response. It should be noted that all thresholds or values ​​should be a range of values.

[0033] Further extensions based on this embodiment, refer to... Figure 6A communication switch is provided between the output of the comparator and the input of the microprocessor. The communication switch is electrically connected to Timer 2. The combination of the communication switch and Timer 2 achieves a delayed start effect. Under normal circumstances, the preset temperature will not exceed 100℃, because if the towel is taken out at 100℃, it will be too hot to handle and will not be comfortable for the user. The temperature will also drop rapidly after being exposed to the outside space, which will not meet the usage requirements. The best way is to be able to use it as soon as it is taken out. Therefore, the preset temperature is generally between 40℃ and 60℃. To ensure the towels are more hygienic, Timer 2 is electrically connected to the start switch, which in turn is electrically connected to the microprocessor. During use, the start switch sends a start signal to the microprocessor. At this time, the start switch simultaneously sends signals to both the microprocessor and Timer 2. Timer 1 can also be activated simultaneously without significant impact. The communication switch is closed, preventing the comparator from sending signals to the microprocessor. Instead, the microprocessor sends a signal to the power manager, causing the heating module to rise to 100°C or higher to disinfect and dry the towels. When Timer 2 reaches its set time, it sends a signal to the communication switch to open it. The microprocessor then receives the signal from the comparator and sends a power adjustment signal to the power manager, reducing the heat output of the heating module and ultimately reaching the desired insulation temperature.

[0034] Based on all the above embodiments, although the power management module is used to provide power to the heating module and the fan 11, the final control switch is located at the microprocessor.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
