In this way, an error of temperature control is large, a large amount of energy is wasted, and the user may have poor experience and feels less comfortable.
In order to solve the technical problems, the present disclosure provides a fabric heating barrel with a graphene heater. In the present disclosure, a graphene composite heating film is attached to an outer wall of a heating cavity to serve as a heating structure. A controller and a temperature sensor are disposed between an outer shell and the heating cavity. The temperature sensor is mounted on the outer wall of the heating cavity to sense a temperature of the graphene composite heating film. The controller is electrically connected to the temperature sensor.

The temperature sensor is configured to sense a temperature of the graphene composite heating film, and the controller is electrically connected to the temperature sensor and the graphene composite heating film.
In some embodiments, the controller is configured as a controllable silicon controller. The controllable silicon controller may control the graphene composite heating film to heat.

In some embodiments, a protrusion is arranged at the bottom of the heating cavity. The graphene composite heating film is attached to a bottom outer surface of the protrusion. The graphene composite heating film is also electrically connected to the temperature sensor and the controller. By controlling heating of the graphene composite heating film, when the temperature inside the graphene composite heating film is about to reach the preset temperature, the controller may decrease the heating power of the graphene composite heating film or may control the graphene composite heating film to stop heating.
In some embodiments, the controller is respectively electrically connected to the graphene composite heating film attached to the outer wall of the heating cavity, the graphene composite heating film attached to the bottom of the heating cavity, and the graphene composite heating film attached to the bottom outer surface of the protrusion. The controller decrease heating powers of the graphene composite heating films disposed at the three locations or controls the graphene composite heating films disposed at the three locations to stop heating.
In some embodiments, a keypad is embedded into the outer shell. The temperature and a heating time length may be set by the keypad. A touch screen is disposed at a side of the keypad. The touch screen is configured to display temperatures of various locations of a wall of the barrel. The user may observe heating temperatures of the graphene composite heating films disposed at various locations. The touch screen is electrically connected to the controller.
According to the above technical solution, the towel or fabric is placed on the inner wall of the outer shell. The heating temperature and the heating time length may be set by the keypad. Subsequently, heating is performed. The heating is achieved by the graphene composite heating film. The heating temperature and the temperature of the graphene composite heating film can be detected in real time by the temperature sensor, and the detected temperatures are displayed on the touch screen.
In some embodiments, the controller and the temperature sensor are mounted on the outer wall or the bottom of the heating cavity.
In some embodiments, a sterilization lamp is embedded in the inner wall of the heating cavity. The sterilization lamp is a UV sterilization lamp and is configured to sterilize the towel that is being heated.
In some embodiments, a cover plate is arranged at a top of the outer shell. A support is arranged at a bottom of the outer shell. A handle is arranged on a top of the cover plate. A sealing gasket is arranged at a location where the outer shell is connected to the cover plate. By arranging the sealing gasket, the cover plate and the outer shell may be connected with each other tightly. The surface of the cover plate is arranged with the handle. The surface of the cover plate on which of the handle is arranged defines a ventilation hole. While heating, the ventilation hole defined in the cover plate may allow air ventilation, preventing the air pressure inside the barrel from being high, and the barrel may not be damaged.
According to the above technical solution, while heating, air ventilation is achieved through a ventilation hole defined in the cover plate, such that an air pressure inside the cover plate may not be high, and the device may not be damaged.

Alternatively, both the drain pipe and the water collection tray may be arranged for discharging the water.
Advantages of the present application are as follows:
The graphene composite heating film is attached to the outer wall of the heating cavity to serve as the heating structure. The controller and the temperature sensor are disposed between the outer shell and the heating cavity. The temperature sensor is configured to sense the temperature of the graphene composite heating film.

Due to the far-infrared and thermal radiation heating principle of the graphene, the temperature is more uniform. Compared to a traditional resistance heating member, the graphene composite heating film is more energy-efficient.
The controller may be a controllable silicon controller. When the temperature is about to reach the preset temperature, the controllable silicon controller may reduce a heating power of the graphene composite heating film, instead of directly shutting down heating of the graphene composite heating film.

In order to solve technical problems in the art, embodiments of the present disclosure provide a fabric heating barrel with a graphene heater. In the present disclosure, a graphene composite heating film is attached to an outer wall of a heating cavity to serve as a heating structure. A controller and a temperature sensor are disposed between an outer shell and the heating cavity. The temperature sensor is mounted on the outer wall of the heating cavity and senses a temperature of the graphene composite heating film. The controller is electrically connected to the temperature sensor. The controller may be configured as a controllable silicon controller. Due to the far-infrared and thermal radiation heating principle of the graphene of the graphene composite heating film, and due to the heating being controlled by the controller, when the temperature is about to reach the preset temperature, the controller may reduce a heating power of the graphene composite heating film, but may not directly shut down the heating of the graphene composite heating film. In this way, the temperature is more stable, an error of the temperature and the preset temperature is small, and the user experience is improved. In addition, the graphene composite heating film may be attached to the outer wall of the heating cavity and an inner wall of a protrusion, such that a heating efficiency and a drying efficiency are improved.
The present embodiment provides a specific structure of a fabric heating barrel with a graphene heater, as shown in
A controller 9 and a temperature sensor 10 are disposed between the outer shell 1 and the heating cavity 13. The controller 9 and the temperature sensor 10 are mounted on the outer wall or the bottom of the heating cavity 13 and sense a temperature of the graphene composite heating film 7. The controller 9 is electrically connected to the temperature sensor 10 and the graphene composite heating film 7.
The controller 9 may be configured as a controllable silicon controller. Specifically, the controller 9 is disposed at a bottom of the outer shell 1 and at an interior of the outer shell 1. Since graphene of the graphene composite heating film 7 has the far-infrared and thermal radiation heating principle, and since the controller 9 may control the heating, when the temperature inside the graphene composite heating film 7 is about to reach a preset temperature, the controller 9 decreases a heating power of the graphene composite heating film 7, instead of directly shutting down the heating of the graphene composite heating film 7. In this way, the temperature is more stable, and an error between the temperature and the preset temperature is small, such that a constant temperature may be reached, and the user experience may be improved.
In some embodiments, a protrusion 8 is arranged at the bottom of the heating cavity 13. The graphene composite heating film 7 is attached to a bottom outer surface of the protrusion 8. The graphene composite heating film 7 is also electrically connected to the temperature sensor 10 and the controller 9. Heating of the graphene composite heating film 7 is controlled by the controllable silicon controller. When the temperature inside the graphene composite heating film 7 is about to reach the preset temperature, the controllable silicon controller may decrease the heating power of the graphene composite heating film 7.
In some embodiments, the controller 9 is respectively electrically connected to the graphene composite heating film 7 attached to the outer wall of the heating cavity 13, the graphene composite heating film 7 attached to the bottom of the heating cavity 13, and the graphene composite heating film 7 attached to the bottom outer surface of the protrusion 8. The controller 9 decrease heating powers of the graphene composite heating films 7 disposed at the three locations or controls the graphene composite heating films 7 disposed at the three locations to stop heating.
Of course, the user may replace the controllable silicon controller with a relay. When the temperature of the graphene composite heating films 7 reaches the preset temperature or is about to reach the preset temperature, the relay is configured to directly shut down a heating function of the graphene composite heating film 7.
A keypad 12 is embedded into the outer shell 1. The temperature and a heating time length may be set by the keypad 12. A touch screen 3 is disposed at a side of the keypad 12. The touch screen 3 is configured to display temperatures of various locations of a wall of the barrel. The user may observe heating temperatures of the graphene composite heating films 7 disposed at various locations (including: the outer wall of the heating cavity 13, the bottom of the heating cavity 13, and the bottom outer surface of the protrusion 8). The graphene composite heating films 7 are electrically connected to the controller 9. A power cord 5 is disposed at a side of the outer shell 1. The controller 9 is electrically connected to the power cord 5.
In some embodiments, the temperature sensor may detect in real-time the heating temperatures of the graphene composite heating films disposed at various locations (including: the outer wall of the heating cavity 13, the bottom of the heating cavity 13, and the bottom outer surface of the protrusion 8) and transmit the heating temperatures to the touch screen to be displayed. Depending on situations, the user may operate the keypad 12 and takes the controller 9 to reduce the heating powers of the graphene composite heating films disposed at various locations or to control the graphene composite heating films to stop heating.
In some embodiments, a sterilization lamp 14 is embedded in an inner wall of the heating cavity 13. The sterilization lamp is a UV sterilization lamp to sterilize a towel that is being heated.
A support 4 is arranged at an end of the outer shell 1 away from the cover plate 2. In total, 4 supports are arranged. By arranging the four supports 4, the outer shell 1 is supported by the supports 4. A sealing gasket is arranged at a location where the outer shell 1 is connected to the cover plate 2. By arranging the sealing gasket, the cover plate 2 and the outer shell 1 may be connected with each other tightly. A handle is arranged on a surface of the cover plate 2. The surface of the cover plate 2 on which of the handle is arranged defines a ventilation hole 6. While heating, the ventilation hole 6 defined in the cover plate 2 may allow air ventilation, preventing the air pressure inside the barrel from being high, and the barrel may not be damaged.
In some embodiments, a water collection tray 17 is arranged below the heating cavity 13 and on the inner wall of the outer shell 1. A lower surface of the heating cavity 13 defines a water collection-outlet hole 16. A drain pipe 15 is arranged at and communicated with a bottom end of the water collection-outlet hole 16. Alternatively, the water collection tray 17 is disposed below the water collection-outlet hole 16. In this way, after the towel or the fabric is heated or dried, water inside the heating cavity 13 may flow through the water collection-outlet hole 16 to be received by water collection tray 17 or may flow through the water collection-outlet hole 16 to enter the drain pipe 15 to be discharged. The drain pipe 15 has a certain length and may be communicated with a downcomer 15.
The graphene composite heating film is attached to the outer wall of the heating cavity to serve as the heating structure. The controller and the temperature sensor are disposed between the outer shell and the heating cavity. The temperature sensor senses the temperature of the graphene composite heating film. The controller is electrically connected to the temperature sensor and the graphene composite heating film. Due to the far-infrared and heat radiation heating principle of the graphene, the temperature is more uniform. Compared to the traditional resistance heating member, the graphene composite heating film is more energy-efficient.
The controller may be configured as the controllable silicon controller. Due to the far-infrared and heat radiation heating principle of the graphene composite heating film, when the temperature is about to reach the preset temperature, the controllable silicon controller may reduce the heating power of the graphene composite heating film, instead of directly shutting down heating of the graphene composite heating film. In this way, the temperature is more stable, the error between the temperature and the preset temperature is small, such that the user experience is improved.
In addition, the graphene composite heating film may be disposed at various locations, such as being attached to the outer wall of the heating cavity, the bottom of the heating cavity, and the bottom outer surface of the protrusion.
