Description

Technical Field

[0001] This invention belongs to the field of sauna room heating technology, specifically relating to a sauna room heating system with low electric field and low electromagnetic radiation. Background Technology

[0002] Saunas, also known as saunas, 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, on which water is poured to generate steam. Modern saunas utilize far-infrared radiation and negative ions to achieve their effects. Saunas have various benefits such as weight loss, detoxification, and relief from rheumatism. In far-infrared saunas, to reduce the impact of electric fields and electromagnetic radiation on the health of sauna users, the heating plates need to have low electric fields and low electromagnetic radiation. At the same time, to enhance the sauna's effect, alternating hot and cold baths are commonly used. Specifically, this involves alternating between hot sauna and cold outdoor environments. During the alternation of hot and cold temperatures, blood vessels dilate and contract, enhancing muscle elasticity, exercising blood vessels, improving blood circulation, increasing vascular elasticity and resilience, and improving cardiopulmonary function.

[0003] For example, Chinese patent CN110139407A discloses a far-infrared sauna room with low electric field and low electromagnetic radiation, including: a room body, low electric field and low electromagnetic radiation heating plates, and shielding wires. Multiple low electric field and low electromagnetic radiation heating plates are distributed within the room body, and each heating plate is connected to a corresponding shielding wire. Each heating plate includes: a first insulating layer, a second insulating layer, a third insulating layer, a fourth insulating layer, a fifth insulating layer, a first electric field shielding layer, a second electric field shielding layer, a first heating element, and a second heating element. The second and third insulating layers are respectively disposed on the upper and lower surfaces of the first heating element, and the first electric field shielding layer is disposed between the second and third insulating layers. Between an insulating layer, the second heating element is disposed on the lower surface of the third insulating layer, the fourth insulating layer is disposed on the lower surface of the second heating element, and the second electric field shielding layer is disposed between the fourth and fifth insulating layers. The first insulating layer has concave and / or convex dots. The shielding wire includes: a power supply stranded wire, an electric field absorbing shielding layer, and a wire insulation layer. The electric field absorbing shielding layer covers the outside of the power supply stranded wire, and the wire insulation layer covers the outer ring of the electric field absorbing shielding layer. Through the setting of the first and second electric field shielding layers, the electric field radiation of the heating plate is absorbed and then conducted to the ground through the ground wire. Since the sinusoidal alternating currents of the two heating elements are out of phase, the electromagnetic waves generated by each are out of phase. After the two are superimposed, the electromagnetic wave radiation is effectively canceled.

[0004] However, the above solution has the following shortcomings: The low electric field and low electromagnetic radiation heating plate, which is composed of low electric field and low electromagnetic radiation, is arranged in a ring inside the sauna room to realize the heating system inside the sauna room. When sauna users need to take a hot and cold bath, they can only go out of the sauna room to the cold environment outside for a cold bath. The existing heating system does not have a hot and cold alternation device, and most of the heat inside the sauna room is concentrated in the upper space. How to introduce the heat from the upper space inside the sauna room to the sauna users while also realizing the function of hot and cold alternation according to the needs of the sauna users is a problem that needs to be solved at present. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sauna heating system with low electric field and low electromagnetic radiation, comprising a sauna body and a heating plate with low electric field and low electromagnetic radiation arranged circumferentially inside it, the outer side of the heating plate being covered with an anti-scalding box, a circulating fan and a cold air fan being respectively arranged on the outer side of the sauna body, a transfer air box being slidably arranged on the rear wall inside the sauna body, and a temperature-conducting exhaust pipe being rotatably arranged on both sides of the transfer air box, and a lifting assembly being arranged between the top wall inside the sauna body and the transfer air box for lifting the temperature-conducting exhaust pipe;

[0007] The air intake end of the circulating fan draws in hot air from the upper part of the sauna room and discharges it through the exhaust end via the transfer air box and the temperature-conducting exhaust pipe.

A flow-adjusting block is provided at the outer end of the return spring sleeve rod and is used to adjust the opening and closing size of the outer opening.

[0012] Preferably, the lifting assembly includes a drive motor mounted on the top of the sauna room, a lifting screw mounted on the output shaft of the drive motor, and the lower part of the lifting screw rotatably mounted on the bottom of the guide rail plate via a bearing seat. The upper and lower end faces of the transfer air box are respectively provided with an air inlet and a lifting screw hole. The lifting screw passes through the air inlet and the lifting screw hole. The upper end face of the transfer air box is provided with a corrugated telescopic air pipe covering the outside of the air inlet.

[0013] Preferably, the air conditioning assembly includes a connecting air pipe that connects to the upper side wall of the corrugated telescopic air duct.

The cooler discharges outside cooling air into the sauna room through the connecting air pipe, the corrugated telescopic air duct, the transfer air box, and the temperature-conducting exhaust pipe in sequence.

[0014] When the air cooler and the second electrically controlled air valve are closed, the circulating fan and the first electrically controlled air valve are open.

It can introduce the heat of the upper part of the sauna room into the sauna user, and can also realize the function of alternating hot and cold bath according to the needs of the sauna user.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Please see Figure 1-7 The present invention provides a technical solution:

[0027] Example 1:

[0028] A sauna heating system with low electric field and low electromagnetic radiation includes a sauna body 1 and a low electric field and low electromagnetic radiation heating plate 2 arranged circumferentially inside it. The outer side of the low electric field and low electromagnetic radiation heating plate 2 is covered with a heat-resistant box 3 made of wood, allowing sauna users to lean against it. The side wall of the heat-resistant box 3 has obliquely oriented hot air holes 203 facing the sauna user's body. The heat generated by the low electric field and low electromagnetic radiation heating plate 2 is transferred to the seated sauna user through the oblique hot air holes 203. A circulating fan 4 and a cold air fan 5 are respectively installed on the outer side of the sauna body 1. All units 5 can use the PY127 type heat-insulated centrifugal fan with compatible specifications produced by Dongguan Puyun Electromechanical Technology Co., Ltd. The model and specifications can be adapted to the usage environment of the circulating fan 4 and the air cooler 5 respectively. The air cooler 5 has a transfer air box 6 slidably installed on the rear wall inside the sauna room body 1. The inner wall of the transfer air box 6 is lined with heat insulation cotton for heat preservation of the transferred gas. Both sides of the transfer air box 6 are connected to the rotating heat conduction exhaust pipe 7. The heat conduction exhaust pipe 7 can rotate relative to the transfer air box 6. The heat conduction exhaust pipe 7 is located outside the anti-scalding plate box 3. A lifting component is installed between the inner top wall of the sauna room body 1 and the transfer air box 6 for lifting the heat conduction exhaust pipe 7.

[0029] The air intake of the circulating fan 4 draws in hot air from the upper inner side of the sauna room 1 and discharges it through the exhaust end via the transfer air box 6 and the temperature-conducting exhaust pipe 7, thereby dispersing the hot air inside the sauna room 1 evenly. An air regulating component is installed between the exhaust end of the cold fan 5 and the exhaust end of the circulating fan 4. The air regulating component controls the amount of hot and cold air discharged into the transfer air box 6. The air intake of the cold fan 5 draws in cold air from the outside environment or cold air generated by an external refrigeration unit, thereby injecting cold air into the sauna room to achieve an alternating hot and cold bath.

[0030] Example 2:

[0031] Based on Embodiment 1, the low electric field and low electromagnetic radiation heating plate 2 possesses the characteristics of low electric field and low electromagnetic radiation. The low electric field and low electromagnetic radiation heating plate 2 contains two heating core plates and two electric field shielding layers, namely a first electric field shielding layer and a second electric field shielding layer. Insulating layers are arranged on both ends of the heating core plates and the electric field shielding layers. The heating core plates are arranged side-by-side, with the two heating core plates located between the two parallel electric field shielding layers. Insulating layers are evenly distributed on the upper and lower surfaces of the heating core plates and the electric field shielding layers. The insulation layer and the sinusoidal alternating current between the heating core board are set in reverse phase. The electric field shielding layer can be made of either aluminum foil or copper foil. Since the far-infrared waves generated by the low electric field and low electromagnetic radiation heating plate 2 are low-to-medium frequency electromagnetic waves, and aluminum foil and copper foil are used to shield high-frequency electromagnetic waves, the use of aluminum foil or copper foil has little impact on the far-infrared waves. By setting the first electric field shielding layer and the second electric field shielding layer, the electric field radiation generated by the heating core board inside the low electric field and low electromagnetic radiation heating plate 2 is absorbed and then conducted to the ground through the ground wire to achieve a low electric field.

[0032] The heating core board inside the low electric field and low electromagnetic radiation heating plate 2 has an insulating layer made of epoxy resin board arranged on both the upper and lower surfaces. The heating core board inside the low electric field and low electromagnetic radiation heating plate 2 can be made of conductive heating graphene or conductive heating carbon. The sinusoidal alternating current between the two heating core boards inside the low electric field and low electromagnetic radiation heating plate 2 is set in opposite phase. Due to the inverse phase of the sinusoidal alternating current between the two heating core boards, the electromagnetic waves generated by each are in opposite phase. After the two are superimposed, and with the reduction of the electric field shielding layer, the electromagnetic wave radiation is effectively reduced.

[0033] A guide rail plate 8 is vertically installed on the inner rear wall of the sauna room body 1, between the adjacent low electric field and low electromagnetic radiation heating plate 2. The guide rail plate 8 has a double ear-shaped cross section. The transfer air box 6 is slidably fitted on the guide rail plate 8 and can slide vertically along the guide rail plate 8.

[0034] Example 3:

[0035] Based on Embodiment 1, a bearing ring connector 9 is further provided on both sides of the transfer gas box 6. The bearing ring connector 9 is composed of a connector pipe connected to both sides of the transfer gas box 6, and a bearing ring is provided on the outer surface of the connector pipe. Both sides of the temperature-conducting exhaust pipe 7 are provided with an opening 10. The temperature-conducting exhaust pipe 7 is fixed to the bearing ring connector 9 by fitting the inner opening 10 to the outside of the bearing ring. A temperature-conducting ring plate 11 is embedded in the temperature-conducting exhaust pipe 7. The temperature-conducting ring plate 11 is made of ceramic material and has heat conduction function. A speed-reducing temperature-conducting mesh plate 12 is provided on the inner ring surface of the temperature-conducting ring plate 11. The deceleration and heat conduction mesh plate 12 is composed of 50 mesh heat-conducting aluminum wires in a cross-shaped pattern. The deceleration and heat conduction mesh plate 12 is set in the gas flow section inside the heat conduction exhaust pipe 7 and reduces the flow velocity of the air and conducts temperature. The hot or cold air flowing into the heat conduction exhaust pipe 7 through the transfer air box 6 is decelerated under the resistance of the deceleration and heat conduction mesh plate 12. At the same time, the airflow is more evenly dispersed. The aluminum deceleration and heat conduction mesh plate 12 transfers the heat or cold of the air to the heat conduction ring plate 11. The heat conduction ring plate 11 contacts the back of the sauna user to achieve the function of hot or cold compress.

[0036] A massage tourmaline stone 13 is circumferentially arranged on the outer surface of the temperature-conducting exhaust pipe 7. As the temperature-conducting exhaust pipe 7 rotates, the tourmaline massage tourmaline stone 13 massages the back of the sauna user. When hot air flows through the temperature-conducting exhaust pipe 7, the massage tourmaline stone 13 generates electrical properties upon heating, providing a therapeutic effect to the sauna user. The outer end face of the massage tourmaline stone 13 is flush with the outer ring face of the temperature-conducting ring plate 11, facilitating simultaneous contact between the sauna user's back and both the massage tourmaline stone 13 and the temperature-conducting ring plate 11. A fixing bracket 14 is provided inside the outer opening 10 of the temperature-conducting exhaust pipe 7. A return spring sleeve 15 is movably inserted through the side wall of the fixing bracket 14. A flow-adjusting block 16 is provided at the outer end of the return spring sleeve 15, used to adjust the opening and closing size of the outer opening 10. The flow-adjusting block 16 is a frustum-shaped structure, and the return spring sleeve 15 generates an inward spring pull on the flow-adjusting block 16. As the airflow velocity inside the temperature-conducting exhaust pipe 7 increases, the airflow will push the flow-adjusting block 16 outward and overcome the reverse spring force generated by the return spring sleeve 15, so that the gap between the opening 10 of the temperature-conducting exhaust pipe 7 and the flow-adjusting block 16 gradually increases, which facilitates the adjustment of the gas discharge volume of the temperature-conducting exhaust pipe 7. At the same time, the frustum-shaped flow-adjusting block 16 makes the exhaust airflow diffuse more widely along its inclined surface. The air discharged through the opening 10 will not blow onto the sauna personnel. The opening 10 faces the inner side walls of the sauna room 1. The temperature changes on the temperature-conducting exhaust pipe 7 are conducted to the sauna personnel through the temperature-conducting ring plate 11.

[0037] The lifting assembly includes a drive motor 17 mounted on the top of the sauna room body 1. The drive motor 17 is a servo motor. A lifting screw 18 is mounted on the output shaft of the drive motor 17 via a coupling. The lower part of the lifting screw 18 is rotatably mounted on the bottom of the guide rail plate 8 via a bearing seat, so as to realize the rotation of the lifting screw 18 in a fixed state. The upper and lower end faces of the transfer air box 6 are respectively provided with an air inlet 19 and a lifting screw hole 20. The lifting screw 18 is fitted through the air inlet 19 and the lifting screw hole 20. The forward and reverse rotation of the output shaft of the drive motor 17 can adjust the forward and reverse rotation of the lifting screw 18, thereby adjusting the raising and lowering of the transfer air box 6. A corrugated telescopic air pipe 21 is provided on the upper end face of the transfer air box 6, which covers the outside of the air inlet 19. The top of the corrugated telescopic air pipe 21 is fixed to the top wall of the sauna room body 1. The corrugated telescopic air pipe 21 has telescopic performance.

[0038] The air conditioning assembly includes a connecting air pipe 22 connected to the upper side wall of the corrugated telescopic air duct 21. An air purification box 23 is installed between the exhaust end of the circulating fan 4 and the air inlet side of the connecting air pipe 22. A first electrically controlled air valve 24 is installed on the side of the air inlet section of the connecting air pipe 22. The exhaust side of the air cooler 5 is connected to the exhaust section side of the connecting air pipe 22 via a second electrically controlled air valve 25. Both the first electrically controlled air valve 24 and the second electrically controlled air valve 25 can be PU225-06 solenoid valves manufactured by Ningbo Senya Solenoid Valve Manufacturing Co., Ltd. The specifications and models of the above solenoid valves are adjusted according to the needs of the usage environment. The first electrically controlled air valve 24, the second electrically controlled air valve 25, and the air cooler 5 are all equipped with air purification boxes 23. The control terminals of the fan 5 and the circulating fan 4 are electrically connected to the controller terminal on the sauna room body 1. The power terminals of the circulating fan 4 and the cooling fan 5 are connected to the external power socket. When the first electrically controlled air valve 24 is closed, the circulating fan 4 is turned off. At this time, the air inside the sauna room body 1 stops circulating. At the same time, the second electrically controlled air valve 25 and the cooling fan 5 are in the open state. The cooling fan 5 discharges the outside cooling air into the sauna room body 1 through the connecting air pipe 22, the corrugated telescopic air guide pipe 21, the transfer air box 6 and the temperature-conducting exhaust pipe 7 in sequence. With the use of the lifting component, the temperature-conducting exhaust pipe 7 rotates along the back of the sauna user. At the same time, the temperature-conducting ring plate 11 transmits the cold sensation to the sauna user.

[0039] When the air cooler 5 and the second electrically controlled air valve 25 are closed, the circulating fan 4 and the first electrically controlled air valve 24 are open. The air intake of the circulating fan 4 draws the hot air from the upper part of the sauna room 1 through the air purification box 23, the connecting air pipe 22, the corrugated telescopic air guide pipe 21, the transfer air box 6, and the temperature-conducting exhaust pipe 7 into the lower space of the sauna room 1. At the same time, the temperature-conducting ring plate 11 transmits the coolness to the back of the sauna user under the conduction of the speed-reducing temperature-conducting mesh plate 12.

[0040] Example 4:

[0041] Based on Embodiment 1, the sauna room 1 has an air vent 101 on its top wall for ventilation, which helps to maintain a constant air pressure inside the sauna room 1. The air purification box 23 is equipped with a dust filter plate 201 and a photocatalytic filter plate 202. The dust filter plate 201 is composed of a 40-mesh dust filter screen, which can filter dust in the air. The dust filter plate 201 and the photocatalytic filter plate 202 are detachable for easy cleaning and maintenance. The photocatalytic filter plate 202 is equipped with an ultraviolet lamp at its lower part. The power supply of the ultraviolet lamp is connected to an external power source. With the help of the ultraviolet lamp, the photocatalytic filter plate 202 can purify harmful gases in the air.

[0042] The working principle is as follows: During the use of sauna room 1, the circulating fan 4, the air cooler 5, the drive motor 17, the first electrically controlled air valve 24, the second electrically controlled air valve 25, and the power supply terminal of the ultraviolet lamp on the photocatalytic filter plate 202 are connected to an external power source in sequence. At the same time, the control terminal is electrically connected to the controller on sauna room 1. During the hot bath process in sauna room 1, the circulating fan 4 and the first electrically controlled air valve 24 are in the open state, resulting in a low electric field and low electromagnetic radiation. The heat generated when the low electromagnetic radiation heating plate 2 is working rises to the upper space of the sauna room 1. The air intake of the circulating fan 4 draws in the hot air from the upper space of the sauna room 1 and filters it through the dust filter 201 and photocatalytic filter 202 inside the air purification box 23. Finally, the air is discharged through the opening 10 at the end of the connecting air pipe 22, the corrugated telescopic air guide pipe 21, the transfer air box 6, and the temperature-conducting exhaust pipe 7. The gap between the opening 10 and the flow regulating block 16 opens and closes. The size is adjusted according to the gas discharge pressure. As the suction power of the circulating fan 4 gradually increases, the gas thrust discharged into the inner surface of the flow regulating block 16 is greater. After overcoming the reverse spring force generated by the reset spring sleeve 15, the opening and closing of the above-mentioned gap is adjusted. At the same time, the frustum-shaped design of the flow regulating block 16 causes the gas to be discharged towards both sides of the lower space of the sauna room 1, which improves the heat distribution of the lower space of the sauna room 1. The output shaft of the drive motor 17 drives the lifting screw 18 to rotate back and forth, so that the transfer air box 6 can perform a cyclical movement of rising and falling under the action of the lifting screw hole 20 on it. The corrugated telescopic air guide pipe 21 ensures that the connecting air pipe 22 introduces hot air into the transfer air box 6 for diffusion. The temperature-conducting exhaust pipe 7 rolls in contact with the back of the sauna user to achieve a massage function. At the same time, the temperature-conducting ring plate 11 warms the back of the sauna user through the heat absorbed by the deceleration temperature-conducting mesh plate 12, which is conducive to the introduction of heat from the lower space to the sauna user.

[0043] When a cold bath is needed through sauna room 1, the circulating fan 4 and the first electrically controlled air valve 24 are closed by the preset control button inside sauna room 1. A dust filter is installed on the air intake side of the cold air blower 5 to filter dust at the air intake end. The cold air blower 5 and the second electrically controlled valve body 25 are opened. The air intake end of the cold air blower 5 draws in cold air from the outside environment or external cooling gas. The cold air is discharged sequentially through the connecting air pipe 22, the corrugated telescopic air guide pipe 21, the transfer air box 6, and the open part 10 at the end of the temperature-conducting exhaust pipe 7. The speed-reducing temperature-conducting mesh plate 12 transmits the cold sensation to the body contact parts of the sauna user through the temperature-conducting ring plate 11. At the same time, the forward and reverse rotation of the lifting screw 18 causes the temperature-conducting exhaust pipe 7 to move up and down, thereby realizing the function of alternating hot and cold baths for the body contact parts of the sauna user according to the needs of use.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
