Description

Technical Field

[0001] This application relates to the field of heating barrels, and more particularly to a towel heating barrel. Background Technology

[0002] A towel heating drum is a device that can heat towels continuously. Heated towels are convenient for users to use in winter, and can also be sterilized at high temperatures after being heated.

[0003] Currently available towel warmers consist of a lid, a body, and a heating element. In use, the lid is typically opened, towels or other fabrics are placed in the container, the lid is closed, and the control panel is manually operated to activate the heating element. After use, the control panel is also manually operated to turn off the heating element. This method of use results in a relatively low level of automation in current towel warmers, making them inconvenient to use. Therefore, it is necessary to improve existing towel warmers.

[0038] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] like Figure 1a , Figure 1b and Figure 2 As shown, this application provides a towel heating bucket 1, including a bucket lid 100, a bucket body 200 connected to the bucket lid 100, and a heating component 300 disposed on the bucket body 200.

[0040] The bucket body 200 has a receiving space 200a for receiving towels to be heated. The bucket lid 100 is closable and connectable to the bucket body 200. Specifically, the bucket lid 100 can be positioned in a first position or a second position. Figure 1a As shown, when the lid 100 is in the first position, the lid 100 closes to the barrel body 200, thereby sealing the opening of the receiving space 200a. Figure 1b As shown, when the lid 100 is in the second position, the lid 100 is open relative to the barrel body 200 to expose at least a portion of the opening of the receiving space 200a.

[0041] In this embodiment, the barrel body 200 includes a barrel outer shell 210 and an inner barrel 220. The receiving space 200a is located inside the inner barrel 220. The barrel outer shell 210 is disposed around the outer peripheral wall of the inner barrel 220 and is spaced apart from the outer peripheral wall of the inner barrel 220, that is, a barrel gap 220a is formed between the outer peripheral wall of the inner barrel 220 and the barrel outer shell 210. In this embodiment, the barrel outer shell 210 includes a first outer shell 211 and a second outer shell 212 connected to the first outer shell 211. The first outer shell 211 and the second outer shell 212 are symmetrically arranged with respect to each other. For example, the first outer shell 211 is disposed corresponding to the left half of the peripheral wall of the inner barrel 220, and the second outer shell 212 is disposed corresponding to the right half of the peripheral wall of the inner barrel 220.

[0042] The first outer shell 211 has a first edge parallel to the central axis of the barrel 200 and a first connector. The first connector is disposed on the first edge and / or on the inner wall of the first outer shell 211 facing the receiving space 200a, near the first edge. The second outer shell 212 has a second edge parallel to the central axis of the barrel 200 and a second connector. The second connector is disposed on the second edge and / or on the inner wall of the second outer shell 212 facing the receiving space 200a, near the second edge. The first connector can be interconnected with the second connector to connect the first outer shell 211 and the second outer shell 212.

[0043] In other embodiments, the outer shell 210 of the barrel may also be integrally formed.

[0044] In this embodiment, the heating component 300 is disposed in the bucket gap 220a and located on the outer peripheral wall of the inner bucket 220. The inner bucket 220 can be made of a material with high thermal conductivity, such as metal, more specifically, iron. Thus, when the heating component 300 heats up, it can heat the inner bucket 220 in a short time to raise the temperature of the receiving space 200a and quickly heat the towels contained within it. It is understood that the bucket gap 220a not only provides space for the heating component 300 but also isolates the inner bucket 220 from the outside air to achieve heat insulation, making it difficult for the inner bucket 220 and the receiving space 200a to dissipate heat.

[0045] like Figure 3 and Figure 4 As shown, Figure 3 This application provides a schematic diagram of the structure of a bucket lid 100 from one perspective according to an embodiment of the present application. Figure 4 This illustration shows a structural schematic diagram of a bucket lid 100 provided in an embodiment of this application from another perspective. The bucket lid 100 includes an upper lid 110 and a lower lid 120 connected to the upper lid 110. After the upper lid 110 and the lower lid 120 are connected, a bucket lid cavity 100a is formed between the upper lid 110 and the lower lid 120.

[0046] In this embodiment, when the lid 100 is in the first position, the lid 100 covers the edge of the inner tub 220 at the opening of the receiving space 200a and the edge of the outer tub 210 near the opening of the receiving space 200a. Thus, when the lid 100 is in the first position, it simultaneously closes the receiving space 200a and the tub gap 220a. At this time, the lid cavity 100a serves as an insulation cavity, cooperating with the outer tub 210 and the tub gap 220a to jointly isolate the heat inside the receiving space 200a of the tub 200 from the outside of the entire towel heating tub.

[0047] Specifically, an upper protruding ring 111 is provided at the center of the upper cover 110, and the upper protruding ring 111 protrudes towards the lid cavity 100a. A lower protruding ring 121 is provided at the center of the lower cover 120, and the lower protruding ring 121 protrudes towards the lid cavity 100a. The upper protruding ring 111 and the lower protruding ring 121 are fitted together.

[0048] The lower cover 120 has a lower cover edge portion, which is a position where it can close with the outer shell 210 of the barrel. Multiple lower cover engaging portions 122 are provided on the inner wall of the lower cover edge portion facing the barrel cover cavity 100a. The upper cover 110 has an upper cover edge portion, which is a position where it can connect with the lower cover edge portion. Multiple upper cover engaging portions 112 are provided on the inner wall of the upper cover edge portion facing the barrel cover cavity 100a. The multiple lower cover engaging portions 122 and the multiple upper cover engaging portions 112 can be engaged and connected in a one-to-one correspondence. For example, one of the lower cover engaging portions 122 and the upper cover engaging portions 112 can be an engaging groove, and the other can be a buckle that mates with the engaging groove. Of course, in other embodiments, other engaging structures can also be used.

[0049] The lower cover 120 has multiple lower cover positioning structures 123 on its inner wall facing the lid cavity 100a at its lower cover edge; the upper cover 110 has multiple upper cover positioning structures 113 on its inner wall facing the lid cavity 100a at its upper cover edge. The lower cover positioning structures 123 and the upper cover positioning structures 113 can be connected to each other for positioning, so that the upper cover 110 and the lower cover 120 can be connected to each other in a preset position. For example, in some embodiments, the lower cover positioning structure 123 can be a positioning hole, and the upper cover positioning structure 113 can be a positioning post that can be inserted into the positioning hole. Of course, in other embodiments, other positioning structures can also be used.

[0050] Therefore, the connection between the upper convex ring 111 and the lower convex ring 121, the connection between the upper cover engaging part 112 and the lower cover engaging part 122, and the connection between the upper cover positioning structure 113 and the lower cover positioning structure 123 make the connection between the upper cover 110 and the lower cover 120 more stable.

[0051] In some embodiments, the lid 100 is also provided with a handle 130, which is located on the side of the lid 110 away from the bucket body 200, so as to facilitate the user to pick up or open and close the lid 100.

[0052] In some embodiments, the upper cover 110 is made of an antistatic material, such as wood, and the lower cover 120 is made of plastic.

[0053] Further reading Figure 2In this embodiment, the inner tub 220 specifically includes an inner tub side wall 221 and an inner tub base 222 connected to one end of the inner tub side wall 221. That is, the inner tub base 222 and the tub lid 100 are located at opposite ends of the inner tub side wall 221. The inner tub side wall 221 and the inner tub base 222 together form a receiving space 200a. The heating assembly 300 is specifically disposed on the inner tub side wall 221.

[0054] The towel heating tub 1 of this embodiment further includes a bottom cover 400, which is connected to one end of the outer casing 210 away from the opening of the receiving space 200a, to close the opening of the inner gap 220a away from the top cover 100. An installation space 400a is formed between the bottom cover 400 and the inner tub base 222 for accommodating electronic components, such as power cords.

[0055] Furthermore, such as Figures 5a-5e As shown, the towel heating bucket 1 provided in this embodiment of the application further includes a first detection component 510, used to detect whether the towel to be heated is contained within the receiving space 200a to obtain a first detection result. It should be understood that, in order to ensure the safety of the towel heating bucket and prevent dry burning due to the absence of any towels or other items to be heated in the bucket, this application provides a first detection component to determine whether any items to be heated are contained in the receiving space 200a. Thus, when no items to be heated are contained in the receiving space 200a, the heating component can be controlled to stop heating.

[0056] Specifically, in this embodiment, the first detection component 510 includes a signal transmitter 511 and a signal receiver 512. The transmitting end of the signal transmitter 511 is positioned facing the receiving end of the signal receiver 512. Figures 5a-5eThe positions of the signal transmitter 511 and the signal receiver 512 are shown. For example, both the signal transmitter 511 and the signal receiver 512 are located on the side wall of the inner tub side wall 221 facing the receiving space 200a; or both the signal transmitter 511 and the signal receiver 512 are located on the inner wall of the inner tub bottom tray 222 facing the receiving space 200a; or one of the signal transmitter 511 and the signal receiver 512 is located on the side wall of the inner tub side wall 221 facing the receiving space 200a, and the other of the signal transmitter 511 and the signal receiver 512 is located on the inner wall of the inner tub bottom tray 222 facing the receiving space 200a. Alternatively, one of the signal transmitter 511 and the signal receiver 512 may be disposed on the inner wall of the lower cover 120 facing the receiving space 200a, and the other of the signal transmitter 511 and the signal receiver 512 may be disposed on the inner wall of the inner tub bottom tray 222 facing the receiving space 200a; or one of the signal transmitter 511 and the signal receiver 512 may be disposed on the inner wall of the lower cover 120 facing the receiving space 200a, and the other of the signal transmitter 511 and the signal receiver 512 may be disposed on the side wall of the inner tub side wall 221 facing the receiving space 200a.

[0057] Understandably, to ensure the accuracy of the detection results, the number of the first detection components can be multiple, namely multiple sets of signal transmitters 511 and corresponding signal receivers 512. For example... Figures 5c-5e as well as Figure 6 As shown, one set of signal transmitters 511 and signal receivers 512 is disposed on the side wall of the inner tub side wall 221 facing the receiving space 200a; another set of signal transmitters 511 and signal receivers 512 is disposed on the inner wall of the inner tub bottom tray 222 facing the receiving space 200a. Alternatively, one set of signal transmitters 511 and signal receivers 512 is disposed on the side wall of the inner tub side wall 221 facing the receiving space 200a, and another set of signal transmitters 511 and signal receivers 512 is disposed on the lower cover 120 and the inner tub bottom tray 222. Alternatively, one set of signal transmitters 511 and signal receivers 512 is disposed on the inner wall of the inner tub bottom tray 222 facing the receiving space 200a, and another set of signal transmitters 511 and signal receivers 512 is disposed on the lower cover 120 and the inner tub bottom tray 222.

[0058] The transmitting end of the signal transmitter 511 is used to transmit a signal, and the receiving end of the signal receiver 512 is used to receive the signal. Due to the placement of the signal transmitter 511 and the signal receiver 512, and their relative arrangement, the signal receiver 512 can receive the signal emitted by the signal transmitter 511 and determine whether a towel to be heated exists within the receiving space 200a based on the received signal. The signal transmitter 511 and the signal receiver 512 can be a pair of photoelectric sensors, a pair of microwave sensors, or a pair of ultrasonic sensors.

[0059] To achieve intelligent control of the towel heating tub 1, the towel heating tub 1 provided in this embodiment of the application is also equipped with a control circuit board 600 (e.g., ...). Figure 2 As shown), the control circuit board is located inside the lid cavity 100a. The control circuit board 600 is equipped with a control circuit and multiple buttons connected to the control circuit, such as... Figure 7 As shown, the main body of the control circuit board 600 is housed in the lid cavity 100a, and multiple buttons are disposed on the outer surface of the upper cover 110. These control buttons are used to receive user input commands and transmit them to the control circuit. The control circuit includes a processor 610 and a heating circuit 310 connected to the processor 610. Simultaneously, a first detection component 510 is connected to the processor 610 and can send signals to the processor 610. The processor 610 controls the operation of the heating circuit 310 based on the signals sent by the first detection component 510 and / or user commands from the buttons. The heating circuit 310 is further connected to the heating assembly 300 for controlling the operation of the heating assembly 300.

[0060] Specifically, the processor 610 controls the heating circuit 310 to turn on to heat the heating component 300 when it receives at least one of a low-level signal and a start command input by the user. That is, the processor automatically controls the heating circuit 310 to turn on to heat the heating component 300 when it receives a low-level signal; or the processor controls the heating circuit 310 to turn on to heat the heating component 300 when it receives both a low-level signal and a start command input by the user; or the processor controls the heating circuit 310 to turn on to heat the heating component 300 when it receives a start command input by the user, but does not need to receive a low-level signal.

[0061] In one embodiment, when the first detection component 510 detects that a towel to be heated is contained in the receiving space 200a, the signal receiver 512 generates a first low-level signal and sends the first low-level signal to the processor 610. In response to receiving the first low-level signal, the processor 610 determines that the received signal is a low-level signal and automatically controls the heating circuit 310 to turn on, heating the heating component 300 to further heat the inner tub 220 to heat the towel to be heated.

[0062] In one embodiment, when the first detection component 510 detects that a towel to be heated is contained in the receiving space 200a, the signal receiver 512 generates a first low-level signal and sends the first low-level signal to the processor 610. The processor 610, in response to receiving the first low-level signal, determines that the received signal is a low-level signal. However, the processor 610 does not immediately control the heating circuit 310 to start working, but waits for a start command from the button. Only after the button receives the start command and sends it to the processor 610 does the processor control the heating circuit 310 to start heating the heating component 300, further heating the inner tub 220 to heat the towel to be heated. The button can be a "start" button 620 (e.g., a physical button or a virtual button on a touch panel). When the user triggers the "start" button, a start command is generated and transmitted to the processor 610.

[0063] In one embodiment, regardless of whether the first detection component 510 sends a low-level signal to the processor, as long as the button receives a start command and sends the start command to the processor 610, the processor can control the heating circuit 310 to turn on to heat the heating component 300, thereby further heating the inner barrel 220.

[0064] Accordingly, the processor controls the heating circuit 310 to stop working and stop heating the heating component 300 when it receives either a high-level signal or a stop command input by the user. In other words, the processor automatically controls the heating circuit 310 to stop heating the heating component 300 when it receives a high-level signal; or the processor controls the heating circuit 310 to stop heating the heating component 300 regardless of whether it receives a high-level signal when it receives a stop command input by the user.

[0065] Specifically, when the first detection component 510 detects that there is no towel to be heated in the receiving space 200a, the signal receiver 512 generates a first high-level signal and sends the first high-level signal to the processor 610. In response to receiving the first high-level signal, the processor 610 determines that the received signal is a high-level signal and automatically controls the heating circuit 310 to stop working, stopping the heating of the heating component 300, thereby further stopping the heating of the inner tub 220. In this way, when there are no towels or other items to be heated in the tub, the towel heating tub 1 will automatically stop heating, avoiding dry burning.

[0066] In one embodiment, when the button receives a stop command and sends it to the processor 610, regardless of whether the first detection component 510 sends a high-level signal to the processor, the processor will control the heating circuit 310 to stop working according to the stop command, thereby stopping the heating of the heating component 300. The button can be a "stop" button 630 (e.g., a physical button or a virtual button on a touch panel). When the user triggers the "stop" button, a stop command is generated and transmitted to the processor 610.

[0067] Furthermore, such as Figure 6 As shown in the embodiment of this application, the towel heating bucket 1 may further include a second detection component 520 for detecting the setting position of the bucket lid 100, that is, detecting whether the bucket lid 100 is closed with the bucket body 200 or whether the bucket lid 100 is open relative to the bucket body 200. It should be understood that, in order to ensure the safety of users when using the heating bucket and to prevent users from being burned by the high temperature of the inner bucket when opening the lid to take out towels during the high-temperature heating process, this application provides a second detection component 520 for determining whether the bucket lid 100 is closed with the bucket body 200, and providing the position information of the bucket lid 100 to the processor so that the processor controls the operation of the heating circuit 310 and the heating component 300.

[0068] Specifically, the second detection component 520 is disposed on the edge of the lid 100 and / or the edge of the body 200. For example, in this embodiment, the lid 100 and the body 200 are pivoted at the connection position so that the lid 100 can be closed or opened by flipping it onto the body 200. Therefore, the second detection component 520 can be disposed at the closed position opposite to the connection position. For example, the second detection component 520 includes a first sensor 521 and a second sensor 522. The first sensor 521 is disposed at the closed position of the lid 100, and the second sensor 522 is disposed at the closed position of the outer shell 210 of the body. The line connecting the connection position and the closed position passes through the central axis of the body. Thus, when the second detection component 520 determines that the lid 100 and the body 200 are closed together, it can accurately determine that the lid 100 completely covers the body 200. Of course, in other embodiments, the second detection component 520 can also adopt other settings, as long as it can correctly determine whether the barrel 200 and the barrel lid 100 are closed or open relative to each other.

[0069] The second detection component 520 generates a corresponding level signal based on the detected setting position (first position or second position) of the bucket lid 100, and transmits the generated level signal to the processor so that the processor 610 controls the operation of the heating circuit 310 according to the level signal.

[0070] Specifically, when the second detection component 520 detects that the lid 100 is in the first position, that is, when the lid 100 is closed with the barrel body 200 to seal the opening of the receiving space 200a, the second detection component 520 (which may be the first sensor 521 and / or the second sensor 522) generates a second low-level signal and transmits the second low-level signal to the processor 610. When the second detection component 520 detects that the lid 100 is in the second position, that is, when the lid 100 is open relative to the barrel body 200 to expose at least a portion of the opening of the receiving space 200a, the second detection component 520 (which may be the first sensor 521 and / or the second sensor 522) generates a second high-level signal and transmits the second high-level signal to the processor 610.

[0071] In other words, in this embodiment, the processor receives both the level signal sent by the first detection component 510 and the level signal sent by the second detection component 520. When the processor receives a first low-level signal sent by the first detection component 510 and a second low-level signal sent by the second detection component 520, it determines that the received signal is a low-level signal; and when the processor receives at least one of the first high-level signal and the second high-level signal, it determines that the received signal is a high-level signal. Similar to the above embodiment, when the processor receives at least one of a low-level signal and a start command input by the user, it controls the heating circuit 310 to turn on to heat the heating component 300.

[0072] In one embodiment, the processor 610 is also used to control the heating circuit 310 to heat the heating component 300 at different power levels, so that the heating component 300 reaches different temperatures. Specifically, the processor 610 is used to control the heating circuit 610 to enter one of a heating stage, a heat preservation stage, or a dehumidification stage.

[0073] During the heating phase, when the temperature reaches the first temperature, heating is applied at the dehumidification power; when the temperature drops to the second temperature, heating is applied again at the heating power to the first temperature. During the heat preservation phase, when the temperature reaches the fourth temperature, heating is applied at the dehumidification power; when the temperature drops to the third temperature, heat is applied again at the heat preservation power to the fourth temperature. During the dehumidification phase, heating is continuously applied at the dehumidification power. In other words, the heating element 300 is continuously heated at a certain power, at least maintaining dehumidification power, to ensure that the inner cylinder does not easily absorb moisture from the air, thus achieving a moisture-proof effect.

[0074] Generally, after the heating stage ends, it automatically enters the heat preservation stage, and after the heat preservation stage ends, it automatically enters the dehumidification stage. Alternatively, corresponding control buttons can be set on the towel heating drum 1, allowing users to selectively enter the heating, heat preservation, or dehumidification stages by manually operating the control buttons.

[0075] It is understood that in some embodiments, the heat preservation stage is omitted, and only the heating stage and the dehumidification stage are retained.

[0076] In one embodiment, when the towel heating tub 1 starts working or the temperature of the towel to be heated is lower than a threshold temperature, the processor 610 controls the heating circuit 310 to enter the heating stage. During the heating stage, the processor 610 controls the heating circuit 310 to heat the heating component 300 with a first heating power to reach a first temperature; then, it heats the heating component 300 with a dehumidification power. Since the dehumidification power is significantly lower than the first heating power, after a certain period of time, the heating component 300 decreases to a second temperature; next, it heats the heating component 300 with a second heating power to reach the first temperature again; and the above-mentioned heating operation with the first heating power, dehumidification power, and second heating power is repeated for a preset time. The cooling power is significantly lower than the first heating power, ranging from 3% to 18% of the first heating power; the second heating power is higher than the cooling power but lower than the first heating power, ranging from 40% to 60% of the first heating power; and the second temperature is lower than the first temperature. For example, the first temperature is 100°C, the second temperature is 95°C, and the preset time is 25 minutes. For example, the first heating power can be 280W-320W, such as 280W, 290W, 300W, 310W, 320W, etc.; the cooling power can be 10W-50W, which is 3%-18% of the first heating power, such as 10W, 11W, 12W, 13W, 14W, 15W, 20W, 25W, 30W, 35W, 40W, 45W, 50W, etc.; the second heating power is 130W-160W, such as 130W, 135W, 140W, 145W, 150W, 155W, 160W, etc. It can be understood that the aforementioned first temperature, second temperature, first heating power, dehumidification power, second heating power, and preset time can also be adjusted to other values ​​within the corresponding numerical range. That is to say, during the heating stage, as long as the heating component 300 is heated to the first temperature range between the first and second temperatures and maintained for the preset time... Once the towel to be heated is within the first temperature range and maintained for a certain period of time, the processor controls the heating circuit to enter the heat preservation stage. During the heat preservation stage, the processor 610 controls the heating circuit 310 to heat the heating component 300 with a cooling power. Since the cooling power is significantly lower than the first heating power, after a certain period of time, the heating component 300 decreases to the third temperature. Then, the heating component 300 is heated with the heat preservation power to reach the fourth temperature (heat preservation threshold). This process is then repeated a preset number of times or for a preset time. The heat preservation power is 12%-30% of the first heating power, and the fourth temperature is higher than the third temperature but lower than the second temperature. In other words, during the heat preservation stage, the temperature of the heating component 300 is controlled within the second temperature range, between the third and fourth temperatures.For example, the insulation power can be 60W, or any value between 40-80W, such as 40W, 45W, 50W, 55W, 60W, 65W, 70W, 75W, 80W, etc.; the third temperature can be 55℃, and the fourth temperature can be 59℃. It can be understood that the insulation power, the third temperature, and the fourth temperature can also be other values; the second temperature range can be: 50℃ to 53℃; 54℃ to 56℃; 57℃ to 59℃; 55℃ to 59℃; 60℃ to 62℃; 60℃ to 64℃; 63℃ to 65℃; 66℃ to 68℃; 65℃ to 69℃; 69℃ to 71℃; 72℃ to 74℃; 75℃ to 77℃; 78℃ to 80℃, etc.

[0077] After the heating and / or heat preservation stages are completed, the processor 610 controls the heating circuit 310 to heat at dehumidification power to enter the dehumidification stage. This is because after heating, the temperature of the inner tub rises, making it easier to absorb moisture from the air. Since the inner tub is made of metal, excessive moisture absorption may cause rusting, thereby damaging the metal or circuitry and other structures, making the towels stored inside the tub prone to dampness and deterioration.

[0078] During the heating and heat preservation process, the high-temperature indicator light will illuminate when the temperature exceeds the set high-temperature threshold. This serves as a reminder to the user not to remove the towel to prevent burns.

[0079] Specifically, the dehumidification stage can begin after at least one of the heating and / or heat preservation stages has ended. The dehumidification stage can begin regardless of whether towels are contained in the receiving space 200a. During the dehumidification stage, the processor controls the heating circuit to heat the heating element 300 at a dehumidification power of less than 50W. That is, during the dehumidification stage, the heating element and inner tub are heated with a lower power; specifically, the heating power of this dehumidification stage is significantly lower than the first power. This prevents moisture accumulation in the metal inner tub, avoiding rusting. Simultaneously, the lower heating power ensures that the temperature of the inner tub 220 does not become excessively high, thus preventing scalding of the user. Specifically, the heating power of this dehumidification stage is 5-50W, which is 1.5%-18% of the first heating power, such as 5W, 10W, 15W, 20W, 25W, 30W, 35W, 40W, 45W, 50W, etc., with a preferred range of 5-15W.

[0080] Furthermore, such as Figure 2As shown, the towel heating tub 1 also includes a power circuit board 700. The power circuit board 700 includes: a power port for connecting to a power supply, such as a power source located outside the towel heating tub 1, to supply power to all electronic components within the towel heating tub; and a converter for converting AC signals into AC zero-crossing signals.

[0081] In this embodiment, the power circuit board 700 is installed in the mounting space 400a between the inner bucket bottom support 222 and the bottom cover 400; while the control circuit board 600 is located in the bucket lid cavity 100a. Thus, the circuit for controlling the heating and stopping of the heating component and controlling the heating power of the heating component (i.e., the control circuit), and the power circuit for managing the power supply, are respectively located in the bucket lid cavity 100a of the bucket lid and the mounting cavity 400a of the bucket bottom. This avoids the two circuits occupying space in the middle of the bucket body, increasing the volume utilization rate of the storage space.

[0082] It is understood that the processor 610 in this application may be an integrated circuit chip with signal processing capabilities. The aforementioned processor 610 may be a general-purpose processor, a DSP, or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor or any conventional processor, etc.

[0083] The towel heating bucket provided in this application includes: a bucket body with a receiving space for storing towels to be heated; a bucket lid connected to the bucket body, the bucket lid being disposed in a first position or a second position; the first position refers to the bucket lid being closed to the bucket body to seal the opening of the receiving space; the second position refers to the bucket lid being open relative to the bucket body to expose at least a portion of the receiving space; a first detection component for detecting whether the towels to be heated are contained in the receiving space to obtain a first detection result; and a heating component disposed on the bucket body for being heated to heat the bucket body to further heat the towels to be heated contained in the receiving space, and for stopping heating according to the first detection result. In this way, the towel heating bucket can automatically control the stopping of heating based on whether there are towels or other items to be heated contained in the receiving space. This prevents dry burning when there are no items to be heated in the bucket and enables automatic stopping of heating, making the towel heating bucket more intelligent and safer.
