[0002] With its innovative live water cleaning technology, the floor washer has become a star product among modern household cleaning appliances, greatly reducing the manual labor intensity of users. However, the cleaning and drying problems of the rear roller brush and the base of the floor washer after use have always been key factors affecting the user experience. Traditional cleaning methods often cannot completely remove the residues on the roller brush, especially grease stains. In addition, the roller brush is in a humid environment for a long time, which is extremely easy to become a breeding ground for bacteria and produce unpleasant odors.

[0003] To address this challenge, technical solutions such as hot water cleaning and hot air drying have emerged on the market. Among them, hot water cleaning uses high-temperature water to dissolve stubborn dirt and enhance the cleaning effect; while hot air drying aims to quickly dry the roller brush to prevent bacteria growth and odor generation. Although these solutions effectively improve the cleaning and sanitation conditions, they usually require the integration of components such as boilers, PTC ceramic heating elements, and fans. This not only significantly increases the cost of the product, but also poses a challenge to the compact design of the floor washer, limiting its portability and aesthetics in the home environment.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

Therefore, it should not be construed as a limitation to the embodiments of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. It should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "set", "installed", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] The following will describe the specific embodiments of the heating device of the present utility model in conjunction with Figure 1 , Figure 2 , Figure 3 and Figure 4 . Among them, Figure 4 The arrows in are respectively used to indicate the water flowing in and out of the heat-conducting water pipe 20, and the air passing through the heat exchange air duct 11.

[0028] The present utility model provides a heating device, including: a heating body housing 10 provided with a heat exchange air duct 11; a heat-conducting water pipe 20 installed in the heating body housing 10 and communicating with the water pipeline of the floor washer; a ceramic heating element 30 integrally arranged in the heating body housing 10 and located between the heat-conducting water pipe 20 and the heat exchange air duct 11. The ceramic heating element 30 is connected to the power supply line to release heat in the energized state. The heating device of the present utility model integrates the heating body housing 10, the heat-conducting water pipe 20 and the ceramic heating element 30, realizing a double improvement in the functions of cleaning and drying the roller brush of the floor washer. Through the integrated design, only one ceramic heating element 30 can simultaneously realize water heating and air heating, greatly reducing the production cost and energy consumption.

[0029] Among them, the heat released by the ceramic heating element 30 when powered on can not only heat the water circuit system of the floor washer through the heat-conducting water pipe 20 to raise the water temperature, thereby enhancing the cleaning ability for stubborn stains (such as grease), but also heat the air through the heat exchange air duct 11 to form hot air, accelerating the drying of the roller brush and the ground, effectively avoiding the growth of bacteria and the generation of peculiar smell, and realizing the dual effects of cleaning and drying. The compact structural design of the heating device, especially the way of embedding the heat-conducting water pipe 20 and the ceramic heating element 30 in the heating element housing 10, greatly reduces the volume of the device, making the floor brush base of the floor washer lighter and easier to store.

[0030] The heating device uses a PTC ceramic heating element 30, which has a positive temperature coefficient characteristic, that is, as the temperature rises, the resistance increases and the heating power automatically decreases, thus realizing self-regulation. Due to its automatic temperature-limiting characteristic, even in abnormal situations, such as overheating, the PTC ceramic heating element 30 can automatically reduce the heating power to prevent the temperature from getting out of control, improving the safety of use. The heating element housing 10 can be a metal part with good heat-conducting performance, preferably the overall material is aluminum, so as to quickly distribute the heat generated by the ceramic heating element 30 evenly throughout the housing, and thus effectively transfer it to the heat-conducting water pipe 20 and the heat exchange air duct 11. The naturally formed oxide film on the surface of the aluminum heating element housing 10 has good corrosion resistance, which can extend the service life of the heating device.

[0031] According to a heating device provided by the present utility model, the heating element housing 10 is provided with a sandwich cavity 12; the shape of the sandwich cavity 12 is adapted to the ceramic heating element 30, so as to be able to detachably install the ceramic heating element 30 in the sandwich cavity 12; the heat-conducting water pipe 20 and the heat exchange air duct 11 are respectively located on both sides of the sandwich cavity 12. Among them, the shape of the sandwich cavity 12 matches the ceramic heating element 30, enabling the heating element to be easily inserted or removed. This detachable design facilitates daily maintenance and replacement work. By respectively placing the heat-conducting water pipe 20 and the heat exchange air duct 11 on both sides of the sandwich cavity 12, the present utility model makes full use of the double-sided heat release characteristic of the ceramic heating element 30. On the one hand, one side of the heating element directly heats the water in the heat-conducting water pipe 20 to raise the water temperature and enhance the cleaning effect; on the other hand, the other side heats the air passing through the heat exchange air duct 11 to generate hot air. This layout not only improves the thermal energy utilization rate but also avoids the mutual interference between the water circuit and the air circuit, ensuring the high efficiency and stability of the heating process.

[0032] According to a heating device provided by the present utility model, the heating element housing 10 is provided with a mounting hole 13 adapted to the outer diameter of the heat-conducting water pipe 20, and the heat-conducting water pipe 20 is inserted into the mounting hole 13. By inserting the heat-conducting water pipe 20 into the mounting hole 13 with an accurately matching size, it can be ensured that the heat-conducting water pipe 20 is firmly fixed on the heating element housing 10. The tight fit between the heat-conducting water pipe 20 and the mounting hole 13 enhances the heat conduction efficiency between the ceramic heating element 30 and the heat-conducting water pipe 20.

[0033] According to a heating device provided by the present utility model, the heat-conducting water pipe 20 is U-shaped, and the two parallel pipe segments of the U-shaped heat-conducting water pipe 20 respectively pass through two parallel mounting holes 13. The design of the U-shaped heat-conducting water pipe 20, combined with the forming process of bending and stretching and the above-mentioned mounting method of tightly fitting with the mounting hole 13, not only optimizes the structural layout of the heating device, but also significantly improves the heat conduction efficiency and heating performance. Specifically, the water inlet and outlet of the heat-conducting water pipe 20 are located on the same side, simplifying the connection between the water pipe and the internal water circuit system of the floor washer. On the other hand, the U-shaped heat-conducting water pipe 20 increases the length of the heat-conducting pipe segment by the U-shaped design, thereby expanding the heat exchange area and improving the heat conduction efficiency.

[0034] According to a heating device provided by the present utility model, aluminum sheets 14 are arranged in the heat exchange air duct 11, and the aluminum sheets 14 divide the heat exchange air duct 11 into a plurality of heat exchange grids. Among them, since aluminum has good thermal conductivity, when the air flow passes through the heat exchange grids divided by the aluminum sheets 14, the heat can be quickly conducted from the heating element to the aluminum sheets 14 and then transferred from the aluminum sheets 14 to the air by the aluminum sheets 14, and this process significantly improves the heat exchange efficiency. Moreover, by dividing the heat exchange air duct 11 into a plurality of independent heat exchange grids, the air can be fully heated in each grid, avoiding the situation of local overheating or insufficient heating, and ensuring the uniformity of air heating. Preferably, the number and size of the heat exchange grids can be adjusted according to actual needs to adapt to different heating powers and air volume requirements.

[0035] According to a heating device provided by the present utility model, the aluminum sheet 14 is bent into a wavy shape and filled in the heat exchange air duct 11, and the peak structure and valley structure of the wavy aluminum sheet 14 are both in close contact with the inner wall of the heat exchange air duct 11. The peak and valley structures of the aluminum sheet 14 not only increase the heat exchange area, but also form a continuous heat conduction path through the close contact with the inner wall of the heat exchange air duct 11, ensuring the rapid and uniform distribution of heat.

[0036] According to a heating device provided by the present utility model, a temperature sensor 31 is arranged on the surface of the heating element housing 10 to be used for real-time detection of the surface temperature of the heating element housing 10. By monitoring the temperature of the heating element housing 10 in real time, the temperature sensor 31 can issue an alarm in time when the temperature rises abnormally, trigger the corresponding protection mechanism, and avoid overheating damage or other safety hazards.

[0037] Preferably, the heating element housing 10 can be provided with a sensor placement groove, which not only realizes the stable installation of the temperature sensor 31, but also ensures the close contact between the sensor and the surface of the housing, making the overall layout of the heating device more compact. The sensor placement groove is preferably located between the two parallel mounting holes 13 described above. This position is closer to the sandwich cavity 12 for setting the ceramic heating element 30, and can more directly reflect the actual working temperature of the heating element, improving the sensitivity and response speed of temperature monitoring.

[0038] According to a heating device provided by the present utility model, the temperature sensor 31 and the ceramic heating element 30 are preferably connected in series in the power supply circuit, which not only simplifies the circuit structure of the heating device, realizes precise temperature control and high energy efficiency, but also enhances the safety and reliability of the device. By connecting the temperature sensor 31 in series with the ceramic heating element 30 to form a closed-loop control system, the temperature sensor 31 can monitor the temperature change of the heating element in real time and feedback the signal to the control circuit. When the temperature reaches the preset value, the circuit can automatically adjust or cut off the power supply to achieve precise temperature control.

[0039] According to a heating device provided by the present utility model, a fuse 32 is provided on the power supply circuit between the temperature sensor 31 and the ceramic heating element 30. As an overload protection device, the fuse 32 can melt when the current in the circuit exceeds the preset threshold, cutting off the power supply. In the heating device, if the ceramic heating element 30 overheats due to some reason, resulting in an abnormal increase in current, the fuse 32 will quickly melt to prevent the temperature from continuing to rise and avoid possible equipment damage or fire risk. The fuse 32 is located in the circuit between the temperature sensor 31 and the ceramic heating element 30. Once an overheating situation occurs, it melts first, which can effectively protect these two key components from damage by high current.

[0040] The following combines Figure 5 and Figure 6 to describe the floor washer provided by the present utility model. The floor washer described below can be correspondingly referred to the heating device described above. Among them, Figure 5 and Figure 6 The arrows in are used to indicate that air enters the air duct of the floor brush base of the floor washer under the action of the fan and flows along the air duct to the position to be dried.

[0041] The present utility model also provides a floor washer configured with the heating device of any of the above embodiments, improving the cleaning and drying performance of the device.

[0042] Specifically, the heating device is arranged in the air duct of the floor scrubber brush base. Among them, the heat exchange air duct 11 is located in the middle section of the air duct, which can efficiently heat the flowing air. The generated hot air is accurately delivered to the roller brush or the ground through the cooperation of the fan and the air duct, accelerating the evaporation of moisture, achieving a fast and thorough drying effect, and avoiding the problems of slippery ground or bacteria breeding on the roller brush after traditional cleaning.

[0043] The temperature sensor 31 is connected in series with the ceramic heating element 30. Combined with the safety protection of the fuse 32, it ensures the intelligent control and safe operation of the heating process, avoids the overheating risk, optimizes the energy utilization at the same time, and achieves the dual goals of efficient cleaning and energy conservation and environmental protection.

[0044] The heat conduction water pipe 20 is connected to the water system of the floor scrubber. It can not only provide preheated water for cleaning, enhance the decontamination ability, especially with remarkable effect when dealing with stubborn stains such as grease, but also be combined with the hot air drying function to provide a comprehensive cleaning and drying solution to meet the cleaning needs of different scenarios.

[0045] The compact layout and efficient heat conduction design of the heating device enable the floor scrubber to achieve miniaturization of volume while maintaining high performance, which is convenient for users to operate and store in a narrow space, improving the portability and usability of the device.
