Technical Field
[0001] This utility model belongs to the technical field of sauna equipment, specifically relating to a heating device for a sauna room. Background Technology
[0002] Saunas, also known as sauna rooms, originated in Finland. They include dry saunas and wet saunas, but the saunas people usually refer to are dry saunas, while steam rooms are wet saunas. Traditional saunas use heated mineral stones and water to generate steam, while modern saunas use far-infrared rays and negative ions to achieve the effects of sauna. Saunas have many benefits such as weight loss, detoxification, and rheumatism relief, and are very popular among consumers.
[0003] However, existing saunas only have one door. This allows cold air to enter the room when people outside open the door, causing a chilly feeling for those inside and greatly reducing their comfort. Adding two doors and a short passageway, along with a heating system in the passageway, would comprehensively upgrade the sauna's insulation, comfort, and energy efficiency. This would be especially suitable for commercial venues with high environmental requirements and families who value a healthy experience. Therefore, it is necessary to propose a sauna heating device to solve the above problems. Utility Model Content

[0006] Furthermore, a seat is fixedly connected to the bottom of the sauna room.
[0007] Furthermore, a support frame is fixedly connected to the bottom of the sauna room, and a storage box is snapped into the inside of the support frame. Volcanic rocks are placed inside the storage box, and handles are fixedly connected to both sides of the storage box. A water pipe is fixedly connected to the side of the inner wall of the sauna room and a fixed box. A valve is provided on the surface of the water pipe. An electric heating tube is fixedly installed inside the fixed box, and a dustproof plate is fixedly connected inside the fixed box.
[0008] Furthermore, the ventilation mechanism includes a drive motor fixedly installed outside the sauna room via a mounting bracket. The sauna room is fixedly connected to four inclined plates. Bearings are fixedly connected to the surfaces of the four inclined plates. A rotating shaft is rotatably connected inside the bearings. One end of the rotating shaft is fixedly connected to the output shaft of the drive motor. Six fan blades are fixedly connected to the surface of the rotating shaft.
[0009] Furthermore, a temperature sensor is installed on the inner wall side of the sauna room, and a controller is fixedly installed on the inner wall side of the sauna room.
[0010] Furthermore, the sauna room has ventilation windows on its inner wall side, and ventilation baffles are fixedly connected inside the ventilation windows. There are four ventilation baffles, and ventilation ducts are fixedly connected to the side of the ventilation windows.
[0011] Furthermore, an indoor light is fixedly installed on the inner wall side of the sauna room.
[0012] Furthermore, the bottom of the sauna room is provided with an anti-slip mat, and the surface of the valve is provided with anti-slip texture.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model provides a heating device for a sauna room. By setting a double-door air-proof mechanism, the first protective door can be opened and closed by hinges and sealed by two sets of magnets. The second protective door adopts a sliding groove design. The double protection greatly reduces heat loss, effectively maintains the temperature in the sauna room, and improves heating efficiency and energy saving. Two electric heating wires are installed in a closed box at the top of the passageway. The passageway is preheated before the user enters the sauna room to prevent cold air from entering at the moment the door is opened, reduce temperature fluctuations, and bring a more comfortable user experience. The top of the passageway is equipped with lighting to facilitate the user's entry and exit.
[0015] 2. This utility model provides a heating device for a sauna room. By incorporating a seat, it provides users with a fixed and stable resting position, avoiding fatigue from prolonged standing. Users can adjust their sitting posture according to their needs, more easily enjoying the sauna process in a high-temperature environment. A storage box is attached to the support frame, containing volcanic rocks. Utilizing the heat storage properties of the volcanic rocks, along with water pipes and valves, users can splash water as needed to quickly generate steam, achieving a traditional sauna experience. The storage box has a handle for easy replacement or cleaning of the volcanic rocks, making maintenance convenient. In addition to heating with volcanic rocks, an electric heating element inside the fixed box can directly heat the air. Complementing the volcanic rock heating, it can meet the temperature needs of different users and provide a stable heat source when the volcanic rock heating is insufficient, ensuring a constant temperature in the sauna. The fixed box is equipped with a dustproof plate to prevent dust, moisture and other contaminants from entering the electric heating tube, avoiding short circuits or equipment damage caused by impurities, extending the service life of the electric heating tube and improving safety. Six fan blades are installed on the rotating shaft and driven by the drive motor to rotate at high speed, which can quickly stir the air in the sauna room. Together with the ventilation window and ventilation duct, it can achieve efficient ventilation, timely expel moisture and stuffy air, and introduce fresh air to keep the indoor air fresh.
[0016] 3. This utility model provides a heating device for a sauna room. A temperature sensor is installed on the inner wall of the sauna room, enabling real-time and accurate sensing of indoor temperature changes and rapid acquisition of temperature data. This provides a reliable basis for temperature control, preventing excessively high or low temperatures. The controller is linked to the temperature sensor and automatically adjusts the power of the heating wire and heating tube, as well as the speed of the drive motor in the ventilation mechanism, based on a preset temperature threshold. When the temperature is too high, the heating power is reduced and ventilation is enhanced; when the temperature is too low, the heating intensity is increased, achieving intelligent maintenance of a constant temperature environment. The ventilation baffle design prevents outdoor dust and debris from entering the sauna room. Ventilation ducts connect to the outside, guiding fresh air in a directed manner to avoid direct airflow onto the body while ensuring even airflow distribution. Given the high temperature and humidity inside the sauna, the indoor lights are made of special high-temperature resistant, waterproof, and moisture-proof materials with a sealed design, enabling stable operation in harsh environments and preventing damage or electrical leakage due to moisture or high temperatures, thus ensuring safe use. The sauna floor is also prone to water accumulation and slipperiness; the inner bottom anti-slip mat increases friction, effectively reducing the risk of slipping. The valve surface features an anti-slip texture design, allowing users to easily and stably operate the valves even with wet or sweaty hands, preventing water leakage due to slippage, providing double protection for user safety.

[0026] The following will provide a more detailed description in conjunction with the accompanying drawings of the embodiments of this utility model. Example 1
[0027] This utility model provides a heating device for a sauna room, including a sauna room 1, a double-door air-blocking mechanism 2, and a ventilation mechanism 12. The double-door air-blocking mechanism 2 includes a passageway 201 fixedly connected to the side of the sauna room 1. A first protective door 202 is movably connected to the side of the passageway 201 via a hinge. A handle 203 is fixedly connected to the side of the first protective door 202. Magnets 204 are provided on both the side of the passageway 201 and the side of the first protective door 202. There are two sets of magnets 204. A closed box 205 is fixedly connected to the top of the passageway 201. Two heating wires 207 are fixedly installed inside the closed box 205. A lighting lamp 206 is fixedly installed on the top of the passageway 201. A sliding groove 2010 is opened inside the sauna room 1. A second protective door 208 is slidably connected inside the sliding groove 2010. A handle 209 is fixedly connected to the side of the second protective door 208.
[0028] In this embodiment, in order to reduce the cold feeling caused by people opening the door and improve the user experience, reference is made to... Figure 1 , Figure 2 and Figure 3 The specific implementation method is as follows: Before entering sauna room 1, the user opens the first protective door 202 by pulling handle 203 (closed by magnet 204). After entering the passageway 201, the user closes the first protective door 202. At this time, the two heating wires 207 in the sealed box 205 are energized and heated to heat the air in the passageway 201, forming a buffer preheating space to reduce heat loss caused by the direct entry of cold outdoor air into sauna room 1. Inside sauna room 1, the second protective door 208 slides through the slide groove 2010 (operated by handle 209), forming a double-door windproof structure with the first protective door 202. When the two doors are closed, the magnet 204 enhances the sealing performance. Together with the lighting lamp 206 at the top of the passageway 201 (providing lighting), it effectively blocks the convection of indoor and outdoor air and improves the heat preservation effect. Then, the user opens the second protective door 208 by using handle 209 and enters sauna room 1. Example 2
[0029] Based on Embodiment 1, this utility model provides a technical solution: Preferably, a seat 4 is fixedly connected to the inner bottom of the sauna room 1, a support frame 5 is fixedly connected to the inner bottom of the sauna room 1, a storage box 6 is snapped into the inside of the support frame 5, volcanic rocks 7 are placed inside the storage box 6, and handles 8 are fixedly connected to both sides of the storage box 6. A water pipe 9 is fixedly connected to a fixed box 10 on the inner side of the sauna room 1, a valve 20 is provided on the surface of the water pipe 9, and an electric heating tube 19 is fixedly installed inside the fixed box 10. A dustproof plate 11 is fixedly connected. The ventilation mechanism 12 includes a drive motor 1201 fixedly installed on the outside of the sauna room 1 via a mounting bracket. An inclined plate 1202 is fixedly connected inside the sauna room 1. There are four inclined plates 1202. Bearings 1203 are fixedly connected to the surface of the four inclined plates 1202. A rotating shaft 1204 is rotatably connected inside the bearings 1203. One end of the rotating shaft 1204 is fixedly connected to the output shaft of the drive motor 1201. Fan blades 1205 are fixedly connected to the surface of the rotating shaft 1204. There are six fan blades 1205.
[0030] In this embodiment, in order to heat and replace the air in the sauna space, reference is made to... Figure 4 , Figure 5 , Figure 6 and Figure 7 The specific implementation method is as follows: After the electric heating tube 19 is powered on, it heats up and heats the surrounding air. The hot air rises and flows through the volcanic rock 7, allowing it to absorb and store heat. When water is poured onto the volcanic rock 7 (the water flow is controlled by the valve 20 of the water pipe 9), the high-temperature volcanic rock 7 comes into contact with the water to generate steam, which quickly increases the indoor humidity and temperature, creating a sauna environment. The dustproof plate 11 prevents volcanic rock 7 particles or dust from entering the area of the electric heating tube 19, avoiding the risk of short circuit. At the same time, it guides the airflow evenly through the heating tube, improving the thermal efficiency. In this way, the user can sit on the seat 4 to enjoy the sauna experience. When it is necessary to replace the air in the sauna room 1, the drive motor 1201 is operated to drive the rotating shaft 1204 to rotate, which in turn causes the six fan blades 1205 to rotate. Then, the stale air in the sauna room 1 is drawn out and discharged through the four ventilation baffles 16 of the ventilation window 15 and the ventilation duct 3, reducing the indoor humidity. Example 3
[0031] Based on Embodiment 2, this utility model provides a technical solution: Preferably, a temperature sensor 13 is provided on the inner wall side of sauna room 1, a controller 14 is fixedly installed on the inner wall side of sauna room 1, a ventilation window 15 is opened on the inner wall side of sauna room 1, a ventilation baffle 16 is fixedly connected inside the ventilation window 15, there are four ventilation baffles 16, a ventilation duct 3 is fixedly connected to the side of the ventilation window 15, an indoor light 17 is fixedly installed on the inner wall side of sauna room 1, an anti-slip pad 18 is provided on the inner bottom of sauna room 1, and an anti-slip texture 21 is provided on the surface of valve 20.
[0032] In this embodiment, for the purposes of temperature monitoring and adjustment, ventilation, and personnel protection, reference is made. Figure 1 , Figure 4 and Figure 7 The specific implementation method is as follows: When entering the sauna room 1, the indoor lights 17 can be turned on to illuminate the sauna room 1. After the sauna is finished, the air and temperature in the sauna room can be discharged through the four ventilation baffles 16 and ventilation ducts 3 of the ventilation window 15. The anti-slip mat 18 and anti-slip texture 21 are both designed to provide a rough adhesion effect for people with wet hands and feet.
