Description

Technical Field

[0001] The utility model relates to the technical field of sauna rooms, in particular to a water tank assembly and a sauna steam engine. Background Art

[0002] Traditional sauna steam engines typically use probe or float detection methods for water level control. In the probe-based detection method, the water level probe is typically mounted on a heated water tank to measure the water level. However, since the water in the tank needs to be heated, the probe quickly accumulates scale, requiring frequent maintenance. Furthermore, due to the limited length of the water level probe, the water level is typically detected using a resistance method. This poses the risk of the probe shorting to the metal outer casing, potentially causing dry heating and damage to the heating element. Clearly, this technology still requires improvement and advancement. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a water tank assembly and a sauna steam engine, aiming to solve the defect in the prior art that the water level probe in the water tank is prone to fouling.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] In the water tank assembly, the auxiliary water tank includes a main body and a cover body arranged on the top of the main body; the main body is provided with an inner cavity extending in the vertical direction, and the upper and lower ends of the main body are respectively provided with a first connecting pipe head for connecting to the main water tank; one end of the water level probe is connected to the cover body, and the other end thereof extends into the inner cavity of the main body.

[0007] In the water tank assembly, the top of the main body is provided with an external rotating buckle, and the cover body is provided with an internal rotating buckle, and the cover body and the main body can be locked after being tightened.

[0008] In the water tank assembly, the cover body is provided with multiple inserts for inserting water level probes; a groove for accommodating a sealing ring is formed between the lower end of the insert and the water level probe, and the water level probe cover is provided with a sealing ring; two annular grooves are also provided at the position where the water level probe is flush with the upper and lower ends of the insert, and a retaining ring is provided at the position of the two annular grooves.

[0013] Beneficial effects:

[0014] The utility model provides a water tank assembly and a sauna steam engine. The water tank assembly comprises a secondary water tank connected to a main water tank, and a water level probe disposed in the secondary water tank.

This reduces the rate of scale accumulation on the water level probe, thereby reducing the difficulty and frequency of maintenance and cleaning. Furthermore, by locating the water level probe in the secondary water tank, the manufacturing process and difficulty of the main water tank are simplified, reducing production costs. Sauna steam engines employing this water tank assembly also experience a reduced rate of scale accumulation on the water level probe, resulting in less frequent maintenance and lower maintenance costs.

DETAILED DESCRIPTION

[0021] The present invention provides a water tank assembly and a sauna steam engine. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention.

[0022] See also Figure 2 、 Figure 3 The present invention provides a water tank assembly that can be used in equipment or devices that need to generate high-temperature steam, such as a sauna steam engine. The water tank assembly includes a main water tank 2, a secondary water tank 3 connected to the main water tank 2, and a control mainboard 4. Specifically:

[0023] The main water tank 2 is a box body 5 with a regular or irregular shape, such as a rectangular parallelepiped, a cube or a cylinder. This embodiment takes the box body 5 with a rectangular parallelepiped structure as an example. A cavity for accommodating water or other heating medium is provided inside the box body 5. A heating mechanism 6, such as an electric heating tube, is also provided in the cavity for heating water or a heating medium that can generate hot steam. The heating mechanism 6 is electrically connected to the control main board 4; the box body 5 is also connected to a water inlet pipe 7, a drain pipe 8, a steam output pipe 9 and a pressure relief pipe 10. Among them, the water inlet pipe 7 is connected to a water source or a heating medium source, and a solenoid valve 11 is provided on the water inlet pipe 7. The solenoid valve 11 is electrically connected to the control motherboard 4 and can be controlled by the control motherboard 4 to replenish water according to the water level inside the main water tank 2; the drain pipe 8 is provided near the bottom of the tank 5, which can be connected to a pipeline provided with an on-off valve, and is used to drain the water or heating medium in the tank 5 when cleaning or repairing the tank 5; the steam output pipe 9 is provided near the top of the tank 5, which is used to connect to the steam delivery pipe for outputting the high-temperature steam generated in the tank 5; the pressure relief pipe 10 is provided with a pressure relief valve 12. When the steam pressure inside the tank 5 is too high or exceeds the limit, the pressure relief valve 12 will open, allowing part of the steam to be discharged through the pressure relief pipe 10, so that the pressure inside the tank 5 is reduced, avoiding the situation where the pressure inside the tank 5 is too high and an explosion occurs, thereby having better safety. In addition, a temperature sensor 23 is also provided on the main water tank 2, and the temperature sensor 23 is electrically connected to the control motherboard 4

[0024] The auxiliary water tank 3 includes a hollow main body 13 and a cover 14 provided on the top of the main body 13. The main body 13 is a cylinder with an inner cavity extending in the vertical direction, but is not limited to a cylinder. It can also be other structures with an inner cavity extending in the vertical direction, preferably a cylinder. In addition, the height of the inner cavity of the main body 13 is the same as or higher than the height of the cavity of the main water tank 2. Two first connecting pipe heads 15 are provided at both ends of the main body 13 or near its two ends. The two first connecting pipe heads 15 are connected to the two second connecting pipe heads 16 provided on the box body 5 of the main water tank 2. The first connecting pipe head 15 is provided with an external thread, and the second connecting pipe head 16 is provided with a movable nut, which is threadedly connected to the first pipe joint through the movable nut, so that the inner cavity of the main body 13 is connected with the cavity of the main water tank 2, and the water level of the main water tank 2 is flush with the water level of the auxiliary water tank 3; in order to know the water level of the main water tank 2, a water level probe 17 is provided on the cover body 14, one end of the water level probe 17 passes through the cover body 14 and extends into the inner cavity of the main body 13, and the other end of the water level probe 17 is connected to the cover body 14 and is electrically connected to the control motherboard 4.

[0025] The control main board 4 is electrically connected to the heating mechanism 6, the solenoid valve 11, the pressure relief valve 12, the temperature sensor 23 and the water level probe 17. It can receive the water level information obtained by the water level probe 17 and the water temperature information obtained by the temperature sensor 23, and open or close the solenoid valve 11 according to the water level information. At the same time, it can also control the heating mechanism 6 to open or close according to the temperature. In addition, the pressure relief valve 12 can be opened or closed according to the size of the air pressure.

[0026] In this embodiment, by providing a secondary water tank 3 connected to the main water tank 2 and installing the water level probe 17 in the secondary water tank 3, since the secondary water tank 3 does not have a heating mechanism 6, the water temperature in the secondary water tank 3 is relatively low, making it less likely for scale to form on the water level probe 17. This can reduce the rate of scale accumulation on the water level probe 17, thereby reducing the difficulty and frequency of maintenance or cleaning. In addition, by installing the water level probe 17 in the secondary water tank 3, the manufacturing process and difficulty of the main water tank 2 can be simplified, thereby reducing the production cost of the main water tank 2.

[0027] Since the water level probe 17 is of a certain length and the water level is generally detected using the resistance method, if the auxiliary water tank 3 is made of metal, there is a possibility that the water level probe 17 will form a path with the metal main body 13. This will cause the water level probe 17 to be unable to obtain the actual water level of the main water tank 2, and ultimately cause dry burning and damage to the heating mechanism 6. In a preferred embodiment, the main body 13 and cover 14 of the auxiliary water tank 3 are both made of plastic. Plastic has good insulation properties. Therefore, the water level probe 17 installed in the auxiliary water tank 3 will not form a path with the main body 13 or cover 14, and the water level height of the main water tank 2 can be accurately measured.

[0028] More preferably, the main body 13 is made of a transparent plastic material, so that the internal situation of the main body 13 can be seen intuitively, which is convenient for observing the water level during production debugging and maintenance.

[0029] Since the internal pressure of the main water tank 2 and the auxiliary water tank 3 is relatively high during operation, the connection between the cover 14 and the main body 13 must be stable. Figure 4 As shown, the top of the main body 13 is provided with an external rotating buckle 18, and the cover 14 is provided with an internal rotating buckle. When the cover 14 and the main body 13 are tightened, they can be locked together, thus being able to withstand high pressure and not easily loosen. In addition, to prevent pressure release from the connection between the cover 14 and the main body 13, a sealing ring 19 is also provided at the connection between the cover 14 and the main body 13.

[0030] In addition, in order to make the fixation of the water level probe 17 more stable and to prevent the pressure from being released from the position where the water level probe 17 is installed, as a further improvement, Figure 4 As shown, the cover body 14 is provided with a plurality of cannulas 20 for inserting the water level probe 17. The inner diameter of the cannulas 20 is adapted to the outer diameter of the water level probe 17. The inner diameter of the lower end of the cannulas 20 is larger than the diameter of the water level probe 17. Therefore, a groove for accommodating a sealing ring 19 is formed between the water level probe 17 and the lower end of the cannulas 20. Therefore, when the water level probe 17 is inserted into the cannulas 20, one or more sealing rings 19 are sleeved on the corresponding grooves of the water level probe 17. In order to fix the water level probe 17 more stably, two annular grooves 21 are further provided at the positions where the water level probe 17 is flush with the upper and lower ends of the cannulas 20, and a snap ring 22 is provided at the positions of the two annular grooves 21. The snap ring 22 can prevent the water level probe 17 from moving up and down, making it more stably fixed. Figure 5 shown.

[0031] Since the temperature of the main box 5 is relatively high during operation, in order to prevent the main box 5 from scalding the user, in a preferred embodiment, Figure 1 As shown, the water tank assembly also includes a shell 1 arranged outside the main water tank 2, the auxiliary water tank 3 and the control main board 4. There is a gap between the shell 1 and the main water tank 2 and the auxiliary water tank 3. Therefore, the heat in the main water tank 2 and the auxiliary water tank 3 is difficult to be transferred to the shell 1, so that the temperature of the shell 1 is lower to avoid scalding the user.

[0032] A second aspect of the present invention further discloses a sauna steam engine for providing hot steam for a sauna room. The sauna steam engine uses the water tank assembly described above. Since the water level probe 17 of the water tank assembly is set at a lower temperature, the water level probe 17 accumulates scale more slowly, thereby reducing the maintenance frequency of the sauna steam engine and lowering the equipment maintenance cost.
