Abstract
Description
Technical Field
[0001] This utility model relates to the field of sauna equipment technology, specifically to a sauna stove with a steam generator. Background Technology
[0002] The origins of saunas are debated, but a common theory is that they originated in ancient Rome. The ancient Romans used charcoal and volcanic rocks to generate heat for health and fitness, which is considered the prototype of the modern sauna.
[0003] Modern sauna heaters heat stones with heating elements, then water is poured onto the heated stone surface to generate steam, causing the sauna room temperature to rise steadily. However, if the water is poured less frequently, the temperature inside the sauna room will be uneven and the humidity will decrease, significantly impacting the user experience.
[0004] If you water too frequently, the stone won't get hot enough to generate enough steam, and repeatedly watering it is also a tedious process. Utility Model Content
[0005] The purpose of this invention is to provide a sauna stove with a steam generator, which aims to solve the problem of high watering frequency and inability to ensure uniform humidity in the sauna room in the existing technology.

[0007] Furthermore, the first heating device includes an inner shell, a first heating element, and a bottom box. The inner shell is connected inside the mounting cavity, the bottom box is located at the bottom of the mounting cavity, and the upper end of the bottom box is provided with a pin interface. The first heating element is vertically arranged inside the inner shell, and the power terminal of the first heating element is plugged into and connected to the pin interface.
[0008] Furthermore, a baffle is provided at the upper end of the base box above the pin interface.
[0009] Furthermore, the inner shell is provided with a shelf, and the shelf is provided with a clearance hole for the first heating tube to pass through.
[0010] Furthermore, the opening at the top of the inner shell is provided with a furnace cap that is inclined toward its center.
[0011] Furthermore, the steam generator also includes a housing that covers the outside of the water tank and is connected to the sauna furnace body, and the top of the housing is provided with a ventilated cover.
[0012] Furthermore, the breathable cover is equipped with aromatherapy accessories.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] like Figure 1 and Figure 2 As shown, a sauna stove with a steam generator 20 includes a sauna stove body 10 and a steam generator 20.
[0026] The sauna stove body 10 has an upward-opening mounting cavity 11 inside, and a first heating device is installed inside the mounting cavity 11. The top of the sauna stove body 10 is equipped with a ventilated top cover 12. The sauna stove body 10 is used to heat the temperature inside the sauna room.
[0027] A steam generator 20 is installed on one side of the sauna stove body 10. The steam generator 20 includes a water tank 21 and a second heating device 22. The water tank 21 is fixedly connected to one side of the sauna stove body 10, and the second heating device 22 is located inside the water tank 21. A steam outlet 211 is provided on the top of the water tank 21. The steam generator 20 is attached to one side of the sauna stove body 10 and is used to heat and boil water, allowing steam to be released into the sauna room, maintaining the continuity of steam output, and ensuring uniform humidity in the sauna room.
[0028] In this embodiment, the first heating device includes an inner shell 13, a first heating tube 14, and a bottom box 15. The inner shell 13 is connected inside the mounting cavity 11, and the bottom box 15 is disposed at the bottom of the mounting cavity 11. The upper end of the bottom box 15 is provided with a pin interface 16. The first heating tube 14 is vertically disposed inside the inner shell 13, and the power terminal of the first heating tube 14 is plugged into and connected to the pin interface 16.
[0029] In specific implementation, the inner shell 13 has a through cavity inside. The inner shell 13 is connected to the inner wall of the mounting cavity 11 at intervals through a connector and is connected to the middle of the mounting cavity 11. The power terminal of the first heating tube 14 is vertically connected to the pin interface 16 on the bottom box 15. The bottom box 15 is provided with a circuit control board that is electrically connected to the first heating tube 14.
[0030] In this embodiment, a baffle 17 is provided at the upper end of the base box 15 above the pin interface 16. The baffle 17 has a V-shaped structure and is mainly used to block some of the water droplets flowing down when the sauna stove is spraying water. It also serves to reflect heat and reduce the temperature of the base box 15.
[0031] In this embodiment, the inner shell 13 has a shelf 131 inside, and the shelf 131 has a clearance hole for the first heating tube 14 to pass through. The two ends of the shelf 131 can be fixed at two-thirds of the height of the sauna stove body 10 by cooperating with the positioning piece of the inner shell 13, so as to support the volcanic rock placed at the sauna stove opening when in use.
[0032] In this embodiment, a furnace cap 132 inclined towards the center is provided at the opening at the top of the inner shell 13. This allows the hot steam generated by the sauna furnace body 10 to diffuse out at an inclined angle, rather than vertically upward.
[0033] In this embodiment, the steam generator 20 also includes a housing 23, which covers the outside of the water tank 21 and is connected to the sauna furnace body 10. The top of the housing 23 is provided with a vent cover 24.

[0034] In this embodiment, an aromatherapy accessory 241 is provided on the ventilated cover 24. This aromatherapy accessory 241 is an aromatherapy bowl made of synthetic low-density air stones, possessing high breathability. It is bowl-shaped and installed on the ventilated cover 24. During operation, aromatherapy sachets or spices can be placed in this bowl to enhance the comfort of the sauna.
[0035] In this embodiment, the water tank 21 is equipped with a water level probe 25, which is made of a circular silicone piece with three stainless steel strips of different lengths inserted in the middle. The top of the stainless steel strips is flat and has an organic wire hole.
[0036] In this embodiment, the bottom of the water tank 21 is provided with an inlet solenoid valve 26 and a drain solenoid valve 26, which are used to add water and drain water from the water tank 21.
[0037] In this embodiment, the second heating device 22 is a second heating tube. The power terminal of the second heating tube is installed at the bottom of the water tank 21. The power of each tube can be selected from 1KW to 3KW and is electrically connected to the circuit control board in the bottom box 15.
[0038] The sauna stove with a steam generator 20 provided by this utility model, compared with the prior art, realizes automatic and continuous steam generation by setting an independent steam generator 20, equipped with a water tank 21 and a second heating device 22, thereby ensuring the humidity in the sauna room and avoiding the tedious process of repeatedly adding water. Compared with the intermittent steam generation method of traditional manual watering, this utility model can maintain the continuity of steam output and effectively solves the problems of large temperature fluctuations and uneven humidity caused by frequent manual watering in traditional technology.
[0039] Where there is no conflict, the above embodiments and features can be combined with each other.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
