Detailed Implementation

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] This embodiment provides a towel machine with internal and external water channels, such as... Figure 1-5As shown, the device includes a body 100, a towel-making device, a hot water system, a towel receiving box 200, and a computer system motherboard 300, all housed within the body 100. The body 100 contains a built-in water tank 400 and a three-way valve 500. An external water inlet 110 is also provided on the body 100. The built-in water tank 400 and the external water inlet 110 are connected to the hot water system via the three-way valve 500, allowing either the external water inlet 110 or the built-in water tank 400 to supply water to the hot water system. When an external water source is connected through the external water inlet 110, the three-way valve 500 can redirect the water flow to the external water channel. In this case, the external water source directly supplies water to the hot water system, enabling the towel machine to operate continuously without relying on the water volume in the built-in water tank 400. If the external water source is unavailable or the demand for towels is low, the three-way valve 500 will switch to the water supply channel of the built-in water tank 400, allowing the water stored in the built-in water tank 400 to flow into the hot water system, ensuring the normal operation of the towel machine.

[0022] This towel machine features dual water supply capabilities, allowing users to choose between external water or the built-in 400 water tank depending on their needs. In restaurants, hotels, and other locations with high towel demand and a stable external water source, direct connection to the external water supply ensures uninterrupted towel production over extended periods. The external water source can be tap water or bottled water. In situations where external water is unavailable, such as temporary events or mobile locations, the built-in 400 water tank provides sufficient water for basic needs. Direct water supply via the external water interface 110 overcomes the limitations of traditional towel machines restricted by the built-in 400 water tank capacity. In high-demand scenarios, it can continuously produce warm, damp towels, meeting the needs of a large number of users simultaneously. This direct external water supply eliminates the tedious process of frequently refilling the built-in 400 water tank, saving labor and time costs and significantly improving the machine's efficiency. For example, in large banquets, traditional towel dispensers may require multiple refills due to insufficient water tank capacity, while this improved towel dispenser can continuously produce towels by relying on external water supply, ensuring that guests can always access warm, moist towels.

[0023] There is no need to excessively increase the size of the equipment to increase the built-in water tank capacity by 400. While ensuring the towel making capacity, the overall size of the towel machine is effectively controlled, making it more flexible in placement and adaptable to different space sizes, thus improving the space adaptability and aesthetics of the equipment.

[0024] like Figure 5As shown, the hot water system includes a heating tank 610, and a water replenishment pump 510 is installed between the heating tank 610 and the three-way valve 500. The three-way valve 500 is a solenoid valve. The computer system motherboard 300 is connected to the three-way valve 500 and the water replenishment pump 510 to control the water path switching of the three-way valve 500 and the operation of the water replenishment pump 510. Relying on the precise control of the solenoid valve and the water replenishment pump 510 by the computer system motherboard 300, the towel machine can accurately adjust the water flow and delivery timing according to the water source status and hot water demand. Whether it is stable water replenishment when supplied by an external water source or on-demand water extraction when supplied by the built-in water tank 400, the hot water system can ensure continuous and stable operation, providing reliable water source support for high-quality towel making. The intelligent monitoring and control of the computer system motherboard 300 enables the solenoid valve to automatically switch according to the water source situation without manual intervention, greatly improving the convenience and reliability of use. Whether the external water source is unexpectedly interrupted or the water level in the built-in water tank is insufficient (400), the towel machine can quickly adjust the water supply method to ensure the continuity of towel production.

[0025] like Figure 5 As shown, the upper end of the heating element 610 is equipped with a vent 611 and a water level sensor 612, while the bottom of the heating element 610 is equipped with a heating plate 613, a temperature sensor 614, and a thermal circuit breaker 615. Relying on the coordinated control of the solenoid valve, the water pump 510, and the water level sensor 612 by the computer system motherboard 300, the towel machine can precisely adjust the water flow and delivery timing according to the water source status, the water level in the heating element 610, and the hot water demand. Whether it is stable water replenishment when supplied by an external water source or on-demand water extraction when supplied by the built-in water tank 400, the hot water system can be guaranteed to operate continuously and stably, providing reliable water source support for high-quality towel making and avoiding excessively low or high water levels in the heating element 610. The temperature sensor 614 and the thermal circuit breaker 615 can prevent the heating element 610 from dry-burning.

[0026] like Figure 5 As shown, the bottom of the heating tank 610 is equipped with a drain pipe 616, and the drain pipe 616 is equipped with a drain valve 617 and a drain interface 618. The drain pipe 616, drain valve 617, and drain interface 618 at the bottom of the heating tank 610 allow the drain interface 618 to be connected to a wastewater tank, providing a convenient maintenance channel for the equipment. When needed, users can open the drain valve 617 to drain the water inside the heating tank 610 through the drain interface 618, facilitating cleaning, disinfection, or troubleshooting maintenance operations. This effectively reduces problems such as bacterial growth and equipment corrosion caused by residual water inside, lowering maintenance difficulty and costs.

[0027] like Figure 4 , 5As shown, the hot water system also includes a spray nozzle 620, and a towel-making water pump 621 is provided between the spray nozzle 620 and the heating tank 610. Precise water volume control and uniform spraying ensure consistent towel moisture, avoiding localized over-wetting or under-drying conditions.

[0028] like Figure 1 As shown, the machine body 100 contains a communication board 310 connected to the computer system motherboard 300. This allows for real-time collection of towel machine operating data recorded by the computer system motherboard 300, such as working time, towel production quantity, water tank level, and heating element 610 temperature. This data is then transmitted to external devices or cloud servers via wired or wireless communication methods, such as Wi-Fi, Bluetooth, 4G / 5G, etc. Simultaneously, the communication board 310 can also receive control commands from external devices, such as mobile apps or remote management platforms, and transmit them to the computer system motherboard 300, enabling remote control and management of the towel machine.

[0029] like Figure 1 , 4 As shown, the towel-making device includes a towel-guiding mechanism 710, a towel-cutting mechanism 720, and a towel-rolling mechanism 730, arranged sequentially according to the towel output sequence and controlled by a computer system motherboard 300. The towel-guiding mechanism 710 quantitatively discharges a complete, continuous roll of towels 800 from the hopper. The towel-cutting mechanism 720 cuts the discharged towels. The towel-rolling mechanism 730 rolls the cut towels. In practice, the towel-guiding mechanism 710 and the towel-cutting mechanism 720 are linked as a single unit via a mechanical mechanism.

[0030] When an external water source is needed, the computer system motherboard 300 sends a command to the three-way valve 500 to switch it to the external water channel. The external water connector is connected to the heating tank 610, and then the water supply pump 510 starts to draw water from the external source to the heating tank 610. When the water source of the built-in water tank 400 is needed, the computer system motherboard 300 controls the three-way valve 500 to switch to the water supply channel of the built-in water tank 400, and the water supply pump 510 draws water stored in the built-in water tank 400 to the heating tank 610.

[0031] The heating plate 613 at the bottom of the heating tank 610 heats the cold water. A temperature sensor 614 at the bottom monitors the water temperature in real time and feeds the data back to the computer system motherboard 300. The computer system motherboard 300 controls the working state of the heating plate 613 according to the preset temperature value to ensure the water temperature reaches a suitable level. During heating, the vent 611 at the top of the heating tank 610 balances the internal air pressure to prevent excessive pressure from affecting equipment safety and operation. The water level sensor 612 monitors the water level in the heating tank 610 in real time. When the water level falls below a set threshold, regardless of whether it is currently supplied by an external water source or the internal water tank 400, the computer system motherboard 300 will control the water pump 510 to start replenishing water. Furthermore, a thermal circuit breaker 615 near the heating plate 613 serves as a safety device. When an abnormally high temperature is detected, it automatically cuts off the power to the heating plate 613 to prevent dangerous situations such as dry burning.

[0032] After the hot water is prepared, the towel-making process begins. The computer system motherboard 300 controls the towel-making water pump 621 to start, drawing hot water from the heating tank 610 and delivering it to the spray nozzle 620. The spray nozzle 620 then evenly sprays the hot water onto the towels being processed by the towel-making device. The towel-making device includes a towel-guiding mechanism 710, a towel-cutting mechanism 720, and a towel-rolling mechanism 730. These three mechanisms are controlled and operate in coordination by the computer system motherboard 300, and the towel-guiding mechanism 710 and the towel-cutting mechanism 720 are linked through a mechanical mechanism. The towel guiding mechanism 710 quantitatively discharges the complete and continuous large roll of towels 800 from the hopper, pulling the large roll of towels 800 out of the hopper at a uniform speed according to a preset length or time interval. When the discharged towel reaches the set length, the computer system motherboard 300 issues an instruction to control the towel cutting mechanism 720 to cut the discharged towel. The cut towel then enters the towel rolling mechanism 730, which rolls the cut towel into small rolls of damp, hot towels, which finally fall into the towel receiving box 200 for the user to take.

[0033] Throughout the operation, the communication board 310 inside the machine body 100 is connected to the computer system motherboard 300, collecting real-time operating data of the towel machine, such as working time, towel production quantity, water tank level, and heating element 610 temperature. This data is then transmitted to external devices or a cloud server via wired or wireless communication. Simultaneously, the communication board 310 can also receive control commands from external devices and transmit them to the computer system motherboard 300, enabling remote control and management of the towel machine, such as remotely setting towel production parameters and starting or stopping the equipment.

[0034] When cleaning or maintenance of the heating element 610 is required, or when a malfunction necessitates draining the internal water, this can be done through the drain pipe 616 at the bottom of the heating element 610. The drain valve 617 on the drain pipe 616 controls the opening and closing of the drain, and the drain interface 618 is used to connect to external drainage equipment to facilitate the drainage of water from the heating element 610, thereby ensuring the normal operation and service life of the equipment.
