Abstract
Description
Technical Field
[0001] This application relates to the field of steam bath equipment technology, and in particular to a steam generating device and a sauna room. Background Technology
[0002] To meet the needs of outdoor and home daily steam baths, a portable sauna device has been launched on the market. This sauna device uses electricity to drive a heating element, which evaporates water to produce high-temperature steam. The sauna typically uses a sauna steam boiler to generate steam. The usable time of the sauna depends on the duration the steam boiler can continuously provide steam, and the steam supply time is closely related to the boiler's capacity. Currently, commonly used sauna steam boilers on the market have capacities of 2.5–6L. Smaller capacity sauna steam boilers (2.5–3.5L) take approximately 8–15 minutes to heat to boiling and can continuously provide steam for 20–25 minutes; larger capacity sauna steam boilers (4–6L) take approximately 18–25 minutes to heat to boiling and can continuously provide steam for 40–50 minutes. Therefore, it is evident that small-capacity sauna equipment has a shorter time from startup to heating to boiling, but the duration of continuous steam supply is also short. While large-capacity sauna equipment provides steam for a longer period, the duration is still relatively short, failing to meet specific time requirements. Furthermore, the longer startup time of large-capacity sauna equipment results in longer waiting times for users. Additionally, large-capacity sauna equipment is approximately 2 to 2.5 times more expensive than small-capacity equipment, making it less economical, and its larger size also reduces portability. Summary of the Invention
[0003] Based on this, this application provides a steam generating device and a sauna room to improve at least one of the problems existing in the prior art, such as short steam supply time, high cost, and poor portability.
[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0030] Please see Figures 1 to 3 The sauna room in this embodiment includes a sauna tent 2, a steam generator 1, and a steam delivery pipe 14. Both ends of the steam delivery pipe 14 are connected to the inner cavity 111 of the sauna tent 2 and the steam generator 1, respectively. The steam delivery pipe 14 can be made of a soft material for easy storage. The sauna tent 2 can be, for example, an outdoor tent or other similar equipment.
[0031] like Figure 3 and Figure 4As shown, the steam generating device 1 includes a steam pot 11 and a connecting assembly 12. The steam pot 11 includes a heater (not shown) and an inner cavity 111. The inner cavity 111 is used to store water, and the heater is used to heat the water in the inner cavity 111 to generate steam for sauna use. The connecting assembly 12 is used to connect the inner cavity 111 and an external container 13, and the external container 13 is used to supply water to the inner cavity 111. A steam outlet pipe 112 is provided at the top of the inner cavity 111 of the steam pot 11. The steam outlet pipe 112 protrudes from the outer wall of the steam pot 11 and is connected to the top space of the inner cavity 111. One end of a steam delivery pipe 14 is sleeved on the steam outlet pipe 112, and the other end extends into the sauna shed 2, so that the steam generated by the steam pot 11 can be delivered to the sauna shed 2 through the steam delivery pipe 14 for sauna use.
[0032] In some embodiments, the steam generator 1 may further include an external container 13 for storing water, or for storing reserve water, to expand the capacity of the inner cavity 111 of the steam boiler 11. In some embodiments, the external container 13 is configured such that its maximum capacity does not exceed the maximum capacity of the inner cavity 111. This design aims to prevent the water supply from exceeding the maximum capacity of the inner cavity 111 when the external container 13 supplies all the water at once. The external container 13 can be equipped with the steam generator 1, for example, it can be integrally connected to the steam boiler 11, or it can be separately installed from the steam boiler 11 for easy storage and transportation. In other embodiments, the external container 13 may not be limited; for example, the external container 13 does not need to be specially equipped and can be a regular bucket, basin, etc. To prevent the water supply from exceeding the maximum capacity of the inner cavity 111, a water level detection device can be installed in the inner cavity 111. That is, when selling goods, the external container can be sold together with the goods, or the external container can be provided by the user. The setting of the external container 13 allows the capacity of the steam generator 1 to be adjusted arbitrarily. For example, when the steam demand is small, the external container 13 can be not used, and steam can be supplied only by the water stored inside the steam pot 11. When the steam demand is large, the external container 13 can be filled to supply water to the steam pot 11. If the steam demand is even greater, water can be added to the external container 13 so that the steam pot 11 can continuously supply steam to meet the greater steam demand, so that the sauna room can truly achieve small size, unlimited capacity, and low cost.
[0033] In some embodiments, such as Figure 3 and Figure 4As shown, the connecting component 12 includes a first connecting pipe 121, a water pumping device 123, and a second connecting pipe 122. The first connecting pipe 121 is inserted into the inner cavity 111, and the second connecting pipe 122 is inserted into the outer container 13. The two ends of the water pumping device 123 are connected to the first connecting pipe 121 and the second connecting pipe 122, respectively, and the water pumping device 123 pumps water from the outer container 13 into the inner cavity 111. The first connecting pipe 121 is preferably fixedly connected to the steam boiler 11, or the first connecting pipe 121 and the inner cavity 111 are sealed together to prevent leakage of liquid or steam at the connection point. The second connecting pipe 122 does not require any connection to the outer container 13; it simply needs to be inserted into the outer container 13.
[0034] In some embodiments, such as Figure 3 and Figure 5 As shown, the connecting component 12 includes a preheating pipe 124, a water pumping device 123, and a second connecting pipe 122. The preheating pipe 124 surrounds and is attached to the outer wall of the inner cavity 111. The water inlet end of the preheating pipe 124 is connected to the second connecting pipe 122, which is used to connect to the external container 13. The water outlet end of the preheating pipe 124 is connected to the inner cavity 111. Both ends of the water pumping device 123 are connected to the preheating pipe 124 and the second connecting pipe 122, respectively, and the water pumping device 123 is used to pump water from the external container 13 into the inner cavity 111. The preheating pipe 124 can be, for example, a copper pipe, which can be designed in a spiral shape and coiled on the outer wall of the inner cavity 111. The connection method between the preheating pipe 124 and the steam boiler 11 is the same as the connection method between the first connecting pipe 121 and the steam boiler 11, and will not be described again. Before entering the inner cavity 111, the water in the outer container 13 first passes through the preheating pipe 124 to absorb the heat dissipated from the inner liner of the steam pot 11, reducing the heat loss of the steam pot 11. At the same time, it reduces the heat absorbed by the cold water after entering the inner cavity 111, which is conducive to providing steam better.
[0035] like Figure 1 and Figure 4 As shown, the inlet of the second connecting pipe 122 can be as close as possible to the bottom of the external container 13 to maximize the water supply from the external container 13 to the steam boiler 11. The outlet of the first connecting pipe 121 or the preheating pipe 124 has no specific requirements and can be located at the upper or lower part of the inner cavity 111. For ease of storage, the second connecting pipe 122 can also be made of a soft material.
[0036] like Figure 4 , Figure 6 and Figure 7As shown, the water pumping device 123 includes a pumping device and a one-way valve 1232 connected together. The one-way valve 1232 is configured so that liquid can only flow from the second connecting pipe 122 to the inner cavity 111 to prevent backflow of water in the inner cavity 111.
[0037] In some embodiments, the pumping device can be a manual device, such as a pumping ball 1231 (e.g., Figure 4 As shown, the inlet end of the squeeze ball 1231 is connected to the second connecting pipe 122, and the outlet end of the squeeze ball 1231 is connected to the one-way valve 1232. By manually pressing the squeeze ball 1231, water in the external container 13 can be pumped into the inner cavity 111.
[0038] In some embodiments, the pumping device may also be an electric water pump, with the inlet end of the electric water pump connected to the second connecting pipe 122, and the outlet end of the electric water pump connected to the one-way valve 1232. After the electric water pump is turned on, it can automatically pump water from the external container 13 into the inner cavity 111.
[0039] Preferably, in some embodiments, a controller (not shown) and a water level detection device (not shown) may also be provided. The controller is used to control the start and stop of the pumping equipment. The water level detection device is located in the inner cavity 111 and is used to detect the water level in the inner cavity 111. The controller can be electrically connected to the water level detection device, and the controller is used to control the start and stop of the pumping equipment according to the detection result of the water level detection device. For example, when the water level detection device detects that the water level in the inner cavity 111 is lower than a first preset value, the controller controls the pumping equipment to start until the water level detection device detects that the water level in the inner cavity 111 reaches a second preset value, at which point the controller controls the pumping equipment to shut down. The second preset value is greater than the first preset value and is not greater than the highest liquid level value in the inner cavity 111. Alternatively, the start and stop of the pumping equipment can also be controlled by the water supply time. For example, when the water level detection device detects that the water level in the inner cavity 111 is lower than the first preset value, the controller controls the pumping equipment to start, and when the start time reaches a preset time, the pumping equipment is shut down.
[0040] In use, a certain amount of water can be filled into both the steam pot and the external container. The steam generated during the heating process in the steam pot is then delivered into the sauna through a steam pipe, allowing for sauna use. When the water level in the steam pot is insufficient, or when additional water is needed under other circumstances, the user can control a pressure ball or electric water pump to pump water from the external container into the steam pot, replenishing the inner cavity of the steam pot. Using the steam generating device of this application, by setting up an external container, the capacity of the steam pot itself can be reduced, while also extending the steam supply time and lowering production costs. Furthermore, during sauna use, if a long waiting time is desired, only a small amount of water can be added to the steam pot to quickly heat it and generate steam. Water is then continuously replenished to the inner cavity through the external container while heating, avoiding the problem of excessively long heating times caused by low power and large water volume in the steam pot. This reduces user waiting time and improves the user experience.
[0041] The steam generator and sauna provided in this application extend the steam supply time of the steam pot by setting an external container, without increasing the size of the inner cavity of the steam pot. This improves the portability of the steam generator and effectively reduces the cost compared to a large-capacity steam pot.
[0042] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
