[0002] Saunas include dry steam rooms and wet steam rooms, but the saunas people usually refer to are dry steam rooms, which use electric heating equipment to directly heat with electricity, releasing heat to increase the temperature in the sauna room and make people sweat.

[0003] Sauna rooms are usually enclosed spaces. When in use, the oxygen inside will gradually be consumed, causing the oxygen concentration to decrease, leading to hypoxia for the user. Directly replacing the outside air into the sauna room will not only affect the comfort level, but also have adverse effects on the body.

[0004] In the prior art, a common method is to heat the air and then send it into the sauna room for ventilation. For example, a Chinese utility model patent document with authorization announcement number CN210568902U discloses a dehumidification ventilation device for a sauna room; another Chinese utility model patent document with authorization announcement number CN221548842U discloses a dehumidification ventilation device for a sauna room. After the air is heated, it is sent into the sauna room, the internal air pressure in the sauna room increases, and the air in the sauna room is pressed out from the gaps such as the door gap to realize the ventilation process. However, the pressed air will be directly discharged with heat, resulting in energy waste.

[0026] like Figures 1 to 5As shown, a control module for a sauna room includes a housing 2, wherein the interior of the housing 2 is divided into a first cavity 24 and a second cavity 25 by a partition 23; a control circuit 1 is arranged inside the first cavity 24, and a heat recovery ventilation component 3 is arranged inside the second cavity 25; the heat recovery ventilation component 3 has a ventilation pipe 31 that passes through the first cavity 24, one end of the ventilation pipe 31 is a ventilation inlet end 311, and the other end of the ventilation pipe 31 is a ventilation exhaust end 312, a heat exchange cavity 33 is arranged inside the ventilation pipe 31, and an air intake heater is arranged between the heat exchange cavity 33 and the ventilation exhaust end 312. 16, the ventilation exhaust end 312 is provided with an intake air temperature sensor 13 for detecting the exhaust temperature of the ventilation pipe 31, and the ventilation pipe 31 is provided with an intake fan 14; the two ends of the heat exchange chamber 33 are respectively connected to the return air intake pipe 36 and the return air exhaust pipe 35, and the air entering the ventilation intake end 311 exchanges heat with the gas discharged from the return air intake pipe 36 in the heat exchange chamber 33; the control circuit 1 has a controller 11, and the controller 11 is connected to an indoor heater 19, an indoor temperature sensor 17 and an oxygen concentration sensor 18, and the intake air temperature sensor 13 and The air intake heaters 16 are all connected to the controller 11; in this embodiment, the controller 11 controls the indoor heater 19 to heat the interior of the sauna room, and detects the real-time temperature inside the sauna room through the indoor temperature sensor 17, and performs feedback adjustment on the indoor heater 19 to keep the temperature inside the sauna room within the set temperature range; the air intake fan 14 drives the air flow through the ventilation pipe 31 into the sauna room, and the sauna room is positively pressurized. The gas inside the sauna room enters the heat recovery ventilation component 3 from the return air intake pipe 36, and the air entering the ventilation intake end 311 is heated in the heat exchange Heat is exchanged between the gas discharged from the cavity 33 and the return air intake pipe 36, and the heat in the gas entering the return air intake pipe 36 inside the sauna room is recovered to reduce heat waste. At the same time, the air entering the ventilation pipe 31 can be preheated to reduce the power consumption of the intake heater 16; the controller 11 can monitor the oxygen concentration inside the sauna room in real time through the oxygen concentration sensor 18. When the oxygen concentration inside the sauna room is lower than the set lower limit, the controller 11 controls the intake heater 16 to preheat, and after the preheating is completed, the intake fan 14 is started for ventilation.

[0027] In the above embodiment, when in use, the sauna room is connected to the return air intake pipe 36 and the ventilation exhaust end 312 through two insulation pipes; in addition, an air filter element can be provided at the ventilation intake end 311 to filter the interior of the ventilation pipe 31.

[0028] In some embodiments, two sealing plates 32 perpendicular to the axis of the ventilation pipe 31 are provided inside the ventilation pipe 31, and the sealing plates 32 are connected to the inner wall of the ventilation pipe 31 on all sides to form an integrated structure, and a heat exchange chamber 33 is formed between the two sealing plates 32; the interior of the heat exchange chamber 33 is evenly provided with heat exchange tubes 34 with bottom ends parallel to the axis of the ventilation pipe 31, and the ends of the heat exchange tubes 34 are connected to the sealing plates 32. External air enters the ventilation pipe 31 and passes through the inside of the heat exchange tubes 34. When the exhaust gas in the sauna room enters the heat exchange chamber 33, it contacts the outside of the heat exchange tubes 34. Heat exchange is performed between the external air and the exhaust gas in the sauna room through the heat exchange tubes 34, which can increase the heat exchange area and thereby improve the heat exchange efficiency. Specifically, the heat exchange tubes 34 can be made of metal materials with excellent thermal conductivity, such as copper or aluminum alloy.

[0029] In some embodiments, the return air inlet pipe 36 is arranged at one end of the heat exchange chamber 33 close to the ventilation exhaust end 312, and the return air exhaust pipe 35 is arranged at one end of the heat exchange chamber 33 close to the ventilation inlet end 311; when the gas in the sauna room enters the heat exchange chamber 33 through the return air inlet pipe 36, the temperature of the gas gradually decreases due to heat exchange, while the temperature of the air introduced from the outside in the ventilation pipe 31 gradually increases. The above-mentioned setting structure of the return air inlet pipe 36 and the return air exhaust pipe 35 can maintain a large temperature difference between the intake air and the return air, thereby ensuring the temperature exchange efficiency; the ends of the return air inlet pipe 36 and the return air exhaust pipe 35 that are away from the heat exchange chamber 33 both extend to the outside of the shell 2.

[0030] In some embodiments, Figure 4 and Figure 6 As shown, conical spoiler rings 341 are evenly arranged on the outer side of the heat exchange tube 34 along its axial direction. The end with a smaller outer diameter in the conical spoiler ring 341 is the air-facing end 3411, and the air-facing end 3411 is close to the return air inlet pipe 36. The conical spoiler rings 341 on adjacent heat exchange tubes 34 are staggered. The conical spoiler rings 341 can disturb the gas entering the heat exchange chamber 33, so that the airflow is evenly distributed on the surface perpendicular to the axial direction of the air exchange tube 31, thereby improving the heat exchange effect. At the same time, the setting of the conical spoiler ring 341 increases the surface area of ​​the heat exchange tube 34, that is, increases the heat exchange area, thereby improving the heat exchange efficiency.

[0031] In some embodiments, a drain pipe 37 is provided at the bottom of the heat exchange chamber 33, and a drain valve 12 is provided on the drain pipe 37. The drain valve 12 is connected to the controller 11. Since the gas exhausted from the sauna room is rich in water vapor, it is easy to produce condensed water during pre-cooling when entering the heat exchange chamber 33. The condensed water will occupy the internal space of the heat exchange chamber 33. After a period of use, the controller 11 can open the drain valve 12 to discharge the condensed water inside the heat exchange chamber 33 to the outside through the drain pipe 37.

[0032] In some embodiments, the controller 11 is connected to a first relay 141, a second relay 161 and a third relay 191; the air intake fan 14 is connected to the first relay 141, the air intake heater 16 is connected to the second relay 161, and the indoor heater 19 is connected to the third relay 191. The controller 11 indirectly controls the air intake fan 14, the air intake heater 16 and the indoor heater 19 by controlling the first relay 141, the second relay 161 and the third relay 191.

[0033] In some embodiments, the controller 11 is connected to an analog-to-digital converter 111, and the intake air temperature sensor 13, the indoor temperature sensor 17 and the oxygen concentration sensor 18 are all connected to the analog-to-digital converter 111, and the analog-to-digital converter 111 is used to complete the analog-to-digital conversion of the sensor; specifically, the analog-to-digital converter 111 is used to convert the intake air temperature analog signal, the indoor temperature analog signal, and the oxygen concentration analog signal of the intake air temperature sensor 13, the indoor temperature sensor 17 and the oxygen concentration sensor 18 into an intake air temperature digital signal, an indoor temperature digital signal, and an oxygen concentration digital signal.

[0034] In some embodiments, a hanging plate 22 is provided on one side of the shell 2, and a hanging hole 221 is opened on the hanging plate 22; a human-machine interface 15 is provided on the side of the shell 2 away from the hanging plate 22, and the human-machine interface 15 is connected to the controller 11; through the human-machine interface 15, the indoor temperature can be set and monitored, the intake air temperature can be set and monitored, and the indoor oxygen concentration can be monitored.

[0035] In some embodiments, a door panel 21 is provided on one side of the first cavity 24, one side of the door panel 21 is hinged to the shell 2, and the other side of the door panel 21 is connected to the shell 2 through a door lock. After unlocking the door lock, the door panel 21 can be opened to maintain the internal control circuit 1.

[0036] In some embodiments, the control circuit 1 has a power supply circuit 112 for supplying power thereto.

[0037] In some embodiments, the second cavity 25 outside the ventilation tube 31 is filled with heat insulating material, and the filling of the heat insulating material forms a heat insulating layer outside the ventilation tube 31, which can reduce the heat loss from the inside of the ventilation tube 31 to the outside.
