Description

Technical Field

[0001] This utility model relates to the field of sauna stoves, and in particular to a sauna stove with humidity control. Background Technology

[0002] Sauna heaters are typically placed inside sauna rooms. They generate high temperatures by heating sauna stones, creating a dry and warm environment inside the sauna room to meet users' needs for sauna use. They are widely used in homes, hotels, gyms, and other settings.

[0003] Commercially available sauna stoves typically only have a heating module, which heats the sauna stones. The sauna stones' heat storage and dissipation properties maintain a high-temperature environment within the sauna room. Humidity control within the sauna room is usually achieved in two ways: one is manual operation, where users directly pour water onto the hot sauna stones based on their own comfort level. The instantaneous vaporization reaction of water upon contact with the hot sauna stones generates steam, thus increasing the humidity inside the room. The other method involves installing a spray system above the sauna stove, which sprays a measured amount of water onto the surface of the sauna stones, using water vaporization to generate steam and regulate humidity.

[0004] However, manually sprinkling water relies entirely on user experience, making it difficult to precisely control the water volume and adjust the humidity to a comfortable range. Even with a metered spray system, the amount of steam generated from the instantaneous contact between water and the high-temperature sauna stones is greatly affected by factors such as the real-time temperature of the sauna stones and the amount of water sprayed, and the steam diffuses quickly, making it impossible to achieve a continuous and stable humidity supply. Ultimately, this results in large fluctuations in humidity within the sauna room, impacting the user's sauna experience and comfort.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

The first heating device is located inside the inner shell and is used to heat the sauna stones; A support plate, located inside the inner shell, is used to support the sauna stone. The support plate has a first through hole for avoiding the first heating device. A steam generator is located in the installation space. The steam generator is equipped with a steam exhaust pipe that extends into the inner shell after passing through the ventilation gap, and is used to introduce steam into the inner shell. A fan, located within the installation space, is used to blow air into the inner casing.

[0009] Furthermore, the inner shell is provided with a V-shaped reflector, which is located below the support plate.

[0010] Furthermore, the inner wall of the inner shell is provided with a baffle plate corresponding to the steam outlet end of the exhaust pipe, which is used to prevent the steam discharged from the exhaust pipe from being directly sprayed toward the first heating device.

[0011] Furthermore, the steam generator also includes a water tank, a second heating device, an inlet pipe, and a drain pipe; the water tank is provided with an orifice plate, and the inlet pipe and drain pipe are both connected to the water tank; the second heating device is located inside the water tank and above the orifice plate; the steam inlet end of the exhaust pipe is connected to the water tank and is located above the orifice plate.

[0017] Beneficial effects: This invention provides a sauna stove with humidity control. A first heating device evenly heats the sauna stones, and a fan introduces cold air to mix with the hot airflow, quickly creating a high-temperature, evenly stable environment in the sauna room. Simultaneously, a steam generator continuously produces steam as needed and discharges it into the inner shell through an exhaust pipe. Driven by the fan's airflow, the steam mixes with the hot airflow and diffuses evenly throughout the sauna room.

Detailed Implementation

[0020] This utility model provides a sauna stove with humidity control. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. 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.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0022] Please see Figures 1 to 6 As shown, this utility model provides a sauna stove with humidity control, including a stove body 1, a first heating device 5, a support plate 2, a steam generator 3, and a fan 4; wherein, the stove body 1 can be a rectangular, square, circular, or elliptical hollow and open three-dimensional structure, but is not limited to the aforementioned structures, and can also be other open three-dimensional structures with internal cavities, preferably an open three-dimensional structure with a rectangular or square cross-section and an internal cavity, and an example is an open three-dimensional structure with a square cross-section and an internal cavity. The furnace body 1 includes an inner shell 11 and an outer shell 12. A ventilation gap 13 is formed between the peripheral walls of the inner shell 11 and the peripheral walls of the outer shell 12. An installation space 14 is formed between the bottom of the inner shell 11 and the bottom of the outer shell 12. A first heating device 5 is disposed inside the inner shell 11 for heating sauna stones. A support plate 2 is disposed inside the inner shell 11 for supporting sauna stones. A first through hole 21 is provided on the support plate 2 to avoid the first heating device 5. A steam generator 3 is disposed inside the installation space 14. The steam generator 3 is provided with an exhaust pipe 31. The exhaust pipe 31 passes through the ventilation gap 13 and extends into the inner shell 11 for introducing steam into the inner shell 11. A fan 4 is disposed inside the installation space 14 for blowing air into the inner shell 11.

[0023] During operation, the first heating device 5 is activated, and some of its heating components act directly on the sauna stones on the support plate 2. Heat conduction and heat radiation achieve uniform heating of the sauna stones. After heating, the sauna stones continuously release heat using their own heat storage characteristics, gradually creating a high-temperature environment inside the inner shell 11 and the entire sauna room. During the heating process, the fan 4 is activated simultaneously, drawing in cold air from the outside and blowing it into the inner shell 11. The air mixes fully with the heat released by the sauna stones to form a hot airflow, which diffuses to all parts of the sauna room to maintain a balanced temperature inside. When humidity control is required, the steam generator 3 starts, and the stable steam generated inside is discharged to the high-temperature environment of the inner shell 11 through the exhaust pipe 31. At the same time, the airflow generated by the fan 4 continuously acts on the inner shell 11, driving the steam to mix with the hot airflow inside the inner shell 11 and evenly diffuse it into the sauna room, avoiding local steam accumulation that would cause a sudden increase in humidity. Through the coordinated action of the on-demand continuous steam production of the steam generator 3 and the airflow diffusion of the fan 4, a stable supply and even distribution of humidity in the sauna room is achieved, eliminating the need for manual watering or reliance on the instantaneous vaporization of sauna stones to generate steam, effectively avoiding large fluctuations in humidity and greatly improving the user's sauna experience comfort. In addition, the first heating device 5, the fan 4, and the steam generator 3 are all integrated into the furnace body 1, with a compact structure; the highly integrated design saves installation space and facilitates user installation and operation.

[0024] It should be noted that temperature detection and control are common practices in the sauna stove industry, and the relevant technical solutions are already in the existing design. Similarly, humidity detection and control are mature and commonly used technologies in the field of temperature and humidity regulation. Applying the aforementioned temperature and humidity detection and control technologies to a sauna stove involves configuring a control panel with external or built-in temperature and humidity sensors. Users can preset target temperature and humidity values, and the control panel integrated with the temperature and humidity sensors, the first heating device 5, and the steam generator 3 establish signal connections. The sensors collect real-time temperature and humidity data within the sauna room and feed it back to the control panel. After comparing the real-time data with the preset values, the control panel controls the opening and closing of the first heating device 5 to adjust the temperature. Simultaneously, control logic is added to control the opening and closing of the steam generator 3 through humidity detection signals. The overall application and logic design described above are conventional technical applications that are easily implemented by those skilled in the art; therefore, their specific structure and working principle will not be elaborated here.

[0025] In a preferred embodiment, see [reference] Figure 4The first heating device 5 includes a positioning strip 51 and a plurality of spaced-apart first serpentine heating tubes 52. The positioning strip 51 is provided with a plurality of slots 511 corresponding to the positions of the first serpentine heating tubes 52, and one slot 511 is correspondingly engaged with one first serpentine heating tube 52. In this embodiment, there are six first serpentine heating tubes 52, and a positioning strip 51 is provided on both sides of the top of every three first serpentine heating tubes 52 to limit and fix the first serpentine heating tubes 52. This ensures that the spacing between adjacent first serpentine heating tubes 52 remains stable and uniform, guaranteeing full coverage and uniform heating of the heating range. It also effectively limits the displacement of the first serpentine heating tubes 52, preventing the first serpentine heating tubes 52 from tilting or shifting due to the squeezing or collision forces generated during the stacking of sauna stones, thereby ensuring the heating stability and safety of the first heating device 5.

[0026] Preferably, see Figure 4 The assembly also includes a locking block 53; the positioning strip 51 has an inverted V-shaped structure, and its opening 511 extends from one side of the positioning strip 51 to the other side, forming a through-type opening 511; the top of the locking block 53 has four symmetrically distributed clamping arms 531; when there are multiple locking blocks 53, one locking block 53 is installed below one corresponding opening 511; when there is only one locking block 53, one locking block 53 is installed below its own opening 511. During assembly, the four clamping arms 531 of the locking block 53 deform under the action of external force to fit against the two sides of the positioning strip 51, cooperating with the positioning strip 51 to lock the top of the first serpentine heating tube 52 in the opening 511. Through the above settings, the connection stability between the first serpentine heating tube 52 and the positioning strip 51 is improved.

[0027] Further, see Figure 2 , 3The inner shell 11 is equipped with a V-shaped reflector 6, which is located below the support plate 2. The V-shaped reflector 6 can concentrate and reflect the heat generated by the first heating device 5 upwards, so that the heat is more concentrated on the sauna stones on the support plate 2, which greatly improves the heating efficiency and heat uniformity of the sauna stones; at the same time, it can effectively block the downward transmission of heat, reduce the heat accumulation in the installation space 14 at the bottom of the furnace body 1, avoid the high temperature from affecting the steam generator 3, fan 4 and other components installed in the space, and extend the service life of the relevant components. Specifically, the reflector plate 6 has several second through holes 61 to avoid the end of the first serpentine heating tube 52. Since the upper part of the first serpentine heating tube 52 is serpentine to expand the heating coverage area, and the lower part is a straight terminal that leads downward, the second through holes 61 only need to be made to match the size of the end of the first serpentine heating tube 52, and its area is much smaller than the area of ​​the first through hole 21. On the one hand, this ensures the smooth installation of the first serpentine heating tube 52 and the normal lead-out of the terminal, and on the other hand, it can minimize the heat loss downward from the second through holes 61, ensuring that most of the heat is guided upward by the reflector plate 6.

[0028] In a preferred embodiment, see [reference] Figure 3 , 6 The inner wall of the inner shell 11 is provided with a baffle 7 corresponding to the steam outlet end of the exhaust pipe 31 to prevent the steam discharged from the exhaust pipe 31 from being directly sprayed toward the first heating device 5. Since the surface temperature of the first serpentine heating tube 52 is as high as 500°C when it is working, while the steam temperature generated by the steam generator 3 is about 110°C, there is a significant temperature difference between the two. If the high-temperature first serpentine heating tube 52 comes into direct contact with the low-temperature steam, it will cause a sudden drop in local temperature, resulting in stress damage to the heating tube material due to uneven thermal expansion and contraction. Long-term use is prone to cracking, aging and other problems, which seriously affect its service life.

[0029] In a preferred embodiment, see [reference] Figure 6The steam generator 3 further includes a water tank 38, a second heating device 32, a water inlet pipe 33, and a drain pipe 34. The water tank 38 is equipped with an orifice plate 35, and both the water inlet pipe 33 and the drain pipe 34 are connected to the water tank 38. The water inlet pipe 33 is connected to an external water source or heating medium source, and a first switch valve 331 is installed on its pipeline. When water or heating medium needs to be replenished, the first switch valve 331 is opened to quantitatively replenish the water tank 38. The drain pipe 34 is located near the bottom of the water tank 38, and a second switch valve 341 is installed on its pipeline. This valve is used to drain any residual water or heating medium from the water tank 38 during cleaning, maintenance, or shutdown, ensuring convenient maintenance operations and equipment cleanliness. The second heating device 32 is located inside the water tank 38 and below the orifice plate 35. Specifically, the second heating device 32 consists of several second serpentine heating tubes. The steam inlet end of the exhaust pipe 31 is connected to the water tank 38 and is located above the orifice plate 35. Preferably, the steam generator 3 further includes an isolation pipe 36 and a liquid level sensor 37. The isolation pipe 36 is vertically installed inside the water tank 38. A third through hole is provided at the bottom and top of the peripheral wall of the isolation pipe 36, allowing communication between the inside of the isolation pipe 36 and the inside of the water tank 38. This ensures that the water level in the isolation pipe 36 remains consistent with the water level in the water tank 38, providing a reference for liquid level detection. The liquid level sensor 37 is vertically installed inside the isolation pipe 36 to detect the liquid level in the isolation pipe 36 in real time, avoiding the impact of water flow disturbances and steam bubbles on detection accuracy when placed directly in the water tank 38. The liquid level sensor 37 feeds back the real-time detected liquid level data to the control panel of the sauna stove. The control panel compares the feedback data with a preset minimum liquid level threshold. When the detected liquid level is below the threshold, it automatically controls the first switch valve 331 on the water inlet pipe 33 to open, promptly replenishing water or heating medium into the water tank 38. When the liquid level reaches the preset normal range, it controls the first switch valve 331 to close, stopping the replenishment.

[0030] In a preferred embodiment, see [reference] Figure 2 , 3The inner shell 11 includes a frame 111, several metal plates 112 arranged around the frame 111, and a first base plate 113 connecting the bottoms of the metal plates 112. The first base plate 113 has several first ventilation holes 1131, and the air outlet of the fan 4 corresponds to one of the first ventilation holes 1131. The frame 111 provides stable support for the overall structure. The multiple metal plates 112 and the first base plate 113 enclose a space for accommodating the sauna stones and the first heating device 5. Combined with the structural design of the first ventilation holes 1131, the cold air introduced by the fan 4 can quickly and evenly enter the interior of the inner shell 11, fully mixing with the heat released by the sauna stones to form a hot airflow; simultaneously promoting the rapid diffusion of steam into the sauna room. Preferably, the air outlet of the fan 4 is provided with an inclined guide plate 41, which extends through the first ventilation hole 1131 into the inner shell 11 to achieve directional airflow. The fan 4 can be a crossflow fan of model 33160.

[0031] Preferably, thermal protectors are provided at the bottom of the first base plate 113 and on the outer wall of the water tank 38. The thermal protectors can be temperature control switches of model KSD301. When the temperature reaches the set value, the bimetallic strip inside the temperature control switch is heated and deformed, triggering the contact to act, cutting off or connecting the circuit. After cooling to the reset temperature, it automatically returns to the initial state to avoid the heating temperature of the first heating device 5 and the second heating device 32 being too high.

[0032] Further, see Figure 2 , 3 The outer shell 12 includes several decorative panels 121 suspended on the frame 111 and a second base plate 122 located at the bottom of the frame 111. The decorative panels 121 may be made of glass and decorated using screen printing or other methods to enhance the appearance of the sauna stove. The second base plate 122 has several second ventilation holes 1221, allowing cold air from the environment to smoothly enter the installation space 14 at the bottom of the stove body 1, forming an efficient air exchange channel with the ventilation gap 13 between the inner shell 11 and the outer shell 12, effectively improving overall airflow. The second base plate 122 has a mounting box 8 for installing the wiring terminals of the first heating device 5. The steam generator 3 is located on the first base plate 113. Specifically, the mounting box 8 is composed of multiple perforated plates 35 spliced ​​together, with its top extending to abut against the first base plate 113, providing auxiliary support for the first base plate 113. The mounting box 8 is equipped with a wiring board 81. The wiring terminals of the first heating device 5 extend through the first base plate 113 into the mounting box 8 and are neatly connected to the wiring board 81 via wires. This facilitates the centralized organization, introduction, and exit of the wires, and also provides protection for the exposed wiring terminals, thereby improving the safety of using the sauna stove.

[0033] Specifically, the back of the decorative panel 121 is provided with a plurality of hook blocks 1211, and the frame 111 is provided with a plurality of hook holes 1111 corresponding to the positions of the hook blocks 1211. The hook blocks 1211 partially pass through the hook holes 1111 and hook onto the hook holes 1111, so that the decorative panel 121 is installed on the frame 111 and a certain distance is maintained between the decorative panel 121 and the metal plate 112, forming a ventilation gap 13. The ventilation gap 13 plays a role in heat insulation, preventing excessive heat from being directly transferred to the decorative panel 121, and also preventing users from accidentally touching the furnace body 1 and getting burned during use.

[0034] In a preferred embodiment, see [reference] Figure 1 The bottom of the second base plate 122 is provided with several support feet 10. The support feet 10 can increase the distance between the second base plate 122 and the ground, so that air can enter the installation space 14, the ventilation gap 13 and the installation box 8 from the second ventilation hole 1221 of the second base plate 122, which promotes heat dissipation and rapid diffusion of steam into the sauna room.

[0035] In a preferred embodiment, see [reference] Figure 5 The system also includes a wire mesh cover 9; a cover plate 15 is provided between the top of the inner shell 11 and the top of the outer shell 12, and the cover plate 15 has several third ventilation holes 151; specifically, the cover plate 15 has a U-shaped structure, and the third ventilation holes 151 are provided on the four sides of the cover plate 15. The cover plate 15 can block the ventilation gap 13 between the inner shell 11 and the outer shell 12 to prevent objects from falling into the ventilation gap 13. At the same time, the third ventilation holes 151 facilitate the ventilation gap 13 to communicate with the outside, promoting the circulation of air and steam. The wire mesh cover 9 is detachably installed on the cover plate 15, and its coverage area corresponds to the opening at the top of the inner shell 11. Through the protective function of the wire mesh cover 9, sauna stones that may roll off due to excessive stacking height or airflow disturbance can be effectively blocked, preventing sauna stones from falling outside the furnace body 1 and causing safety hazards; at the same time, the detachable design also makes it easy for users to disassemble and install the cover according to their needs, facilitating the addition and replacement of sauna stones and the cleaning and maintenance of the inside of the furnace body 1.

[0036] Further, see Figure 5The bottom side of the basket cover 9 is provided with several U-shaped hooks 91 that hook onto the corresponding third ventilation holes 151. On the opposite side, a positioning block 92 is provided, which is engaged with the corresponding third ventilation hole 151. The positioning block 92 has an integrally formed locking foot 921 that can be engaged into the third ventilation hole 151. Specifically, the side of the basket cover 9 away from the U-shaped hooks 91 has a straight section 93, which is slidably connected to the positioning block 92. The positioning block 92 has a threaded hole 922, into which a locking screw is screwed. The end of the locking screw abuts against the straight section 93 to lock the relative position of the straight section 93 and the positioning block 92. The locking screw is not shown in the accompanying drawings. During installation, first align and hook the U-shaped hook 91 on one side of the basket cover 9 to the third ventilation hole 151 on the corresponding side of the cover plate 15. Then adjust the relative position of the positioning block 92 and the straight section 93 of the basket cover 9 so that the locking feet 921 of the positioning block 92 simultaneously engage with the third ventilation hole 151 on the corresponding side of the cover plate 15, achieving initial positioning on both sides. Finally, tighten the locking screws on the positioning block 92 to fix the basket cover 9 to the cover plate 15.

[0037] It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of this utility model, and all such substitutions or modifications should fall within the protection scope of the appended claims.
