Description

Technical Field

[0001] This utility model relates to the field of athlete rehabilitation technology, specifically to an ice bath machine. Background Technology

[0002] In sports training and competition, athletes often experience fatigue and muscle injuries after high-intensity training or matches. Ice baths, as an effective recovery method, can help athletes reduce inflammation, relieve muscle soreness, and promote physical recovery. Traditional ice baths typically involve directly using an ice water pool, but this method has some limitations.

[0003] On the one hand, maintaining the temperature of the ice water pool is quite difficult. As athletes enter the pool, the transfer of body heat causes the water temperature to gradually rise, leading to a continuous decrease in the effectiveness of the ice bath. Furthermore, it requires constantly adding ice to maintain the low temperature, which is inconvenient and costly. On the other hand, the hygiene of the ice water pool is difficult to guarantee; multiple users could lead to cross-infection, which is detrimental to the athletes' health.

[0004] To overcome these problems, ice bath machines have emerged. Existing ice bath machines cool the bath water through a refrigeration system, solving the issues of temperature maintenance and hygiene to some extent. However, current ice bath machines suffer from insufficient efficiency in the condensation stage. During the refrigeration cycle, the performance of the condenser is crucial to the overall system efficiency. Existing ice bath machine condensers often suffer from inefficient heat dissipation due to their structural design and heat dissipation methods. For example, some ice bath machine condensers have limited heat sink area and poor air circulation, causing heat accumulation and affecting the refrigerant's condensation effect. This not only reduces the ice bath machine's refrigeration efficiency and prolongs the time to reach the set low temperature but may also increase energy consumption, failing to meet the needs of athletes for rapid and efficient ice bath recovery after training and competition. Furthermore, inefficient condensation can lead to unstable internal temperatures within the ice bath machine, affecting the quality and effectiveness of the ice bath, which in turn hinders athletes' physical recovery and the smooth implementation of training programs. Therefore, improving the condensation efficiency of ice bath machines has become an important direction for technological improvement. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and 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 based on the specific circumstances.

[0032] This utility model discloses an ice bath machine. See [link to relevant documentation]. Figures 1 to 3 To facilitate the overall structure, the pipe and wiring connections between multiple components are omitted in the attached drawings. The ice bath machine includes an outer shell assembly 1, a cylinder 2 housed inside the outer shell assembly 1, a heat exchanger 3, and a refrigeration device. Specifically, the cylinder 2 is provided with a circulating water outlet 21 and a circulating water inlet 22. In order to reduce the stimulation of cold water, there are two circulating water inlets 22.

[0033] Specifically, the circulation outlet 21 of the cylinder 2 is connected to the first inlet pipe of the heat exchanger 3, and the first outlet of the heat exchanger 3 is connected to the circulation inlet 22 of the cylinder 2 via the pump body 6. By connecting the first outlet of the heat exchanger 3 to the pump body 6, and then connecting the pump body 6 to the circulation inlet pipe of the cylinder 2, a continuous flow of cold water is achieved, enabling dynamic cooling and rapidly cooling the water to 2-3 degrees Celsius. This ensures that during the athlete's use of the cold water bath, cold water is continuously drawn out, cooled, and returned, maintaining the low temperature of the cold water in the cylinder 2.

[0034] Specifically, the output end of the refrigeration device is connected to the second inlet pipe 31 of the heat exchanger 3, and the second outlet 32 ​​of the heat exchanger 3 is connected to the input end of the refrigeration device via a pipe. The refrigeration device includes a coil assembly 41, which is disposed below the cylinder 2. In this embodiment, by directly disposing of the coil assembly 41 below the cylinder 2, water can be cooled from 2-3 degrees Celsius to 0 degrees Celsius more efficiently, forming an ice-free state, thus significantly improving refrigeration efficiency and quickly reaching and maintaining the required low-temperature environment.

[0035] Specifically, the coil assembly 41 includes a first coil assembly 411 and at least one second coil assembly 412. The inner cavity of the second coil assembly 412 is connected to the inner cavity of the first coil assembly 411. The cylinder body 2 includes a bottom plate 23 and a side wall. The side wall is erected on the bottom plate 23 and connected to the edge of the bottom plate 23. The side wall includes a first side wall 24. The first coil assembly 411 is disposed below the bottom plate 23 of the cylinder body 2 and contacts the bottom plate 23. The second coil assembly 412 is disposed outside the first side wall 24 of the cylinder body 2 and contacts the first side wall 24.

[0036] In this embodiment, the first coil assembly 411 cools from the bottom and the second coil assembly 412 cools from the side. This multi-directional cooling layout can cool the liquid in the cylinder more comprehensively, effectively reduce the temperature gradient in the cylinder, and make the liquid temperature more uniform throughout the cylinder. For experiments or processes with extremely high requirements for temperature uniformity, it can significantly improve the reliability and repeatability of the results.

[0037] In this embodiment, the coil assembly 41 is respectively set on the bottom plate 23 and the side wall. Without significantly increasing the overall volume of the ice bath machine, the space around the cylinder is reasonably utilized, making the distribution of the coil assembly 41 more reasonable. This achieves efficient cooling and avoids the local overcooling or other structural inconveniences that may result from the coil assembly 41 being too concentrated. This optimizes the internal structure design of the ice bath machine and improves the overall performance and reliability of the equipment.

[0038] Furthermore, there are two second coil assemblies 412 and two first sidewalls 24. The two first sidewalls 24 are disposed on both sides of the base plate 23. The second coil assemblies 412 are respectively disposed outside the two first sidewalls 24 of the cylinder body 2 and in contact with the bottom of the first sidewalls 24.

[0039] In this embodiment, two second coil assemblies 412 are respectively disposed outside the two first sidewalls 24 of the cylinder and in contact with the bottom plate 23. Compared with the case where the coil is disposed on only one sidewall or does not contact the bottom, the contact area between the coil and the cylinder is greatly increased. During heat exchange (cooling the water in the cylinder), a larger contact area means that more heat can be transferred between the medium (refrigerant) in the coil and the substances in the cylinder, which can accelerate the heat exchange speed and achieve more efficient temperature regulation of the substances in the cylinder. 431

[0040] Furthermore, the refrigeration device also includes a compressor 42, an evaporator 43, and an electronic control unit 44. The electronic control unit 44 is located in the electrical box of the refrigeration device. The outlet 432 of the evaporator 43 and the inlet 421 of the compressor 42 are connected through a return gas pipe 46. The outlet pipe 422 of the compressor 42, the second inlet pipe 31 of the heat exchanger 3, and the inlet 413 (output end of the refrigeration device) of the coil assembly 41 are connected through pipes. The outlet pipe 422 of the compressor 42 is connected to the inlet pipe 431 of the evaporator 43. The outlet 414 (input end of the refrigeration device) of the coil assembly 41 is connected to the second outlet 32 ​​of the heat exchanger 3 and the inlet 433 of the evaporation chamber of the evaporator 43. The heat exchanger 3, the compressor 42, the evaporator 43, and the pump body 6 are electrically connected to the electronic control unit 44. The refrigerant used in the refrigeration device is R410. This embodiment establishes a more efficient refrigeration system through the cooperation of the coil assembly 41, compressor 42, evaporator 43, and electronic control unit 44. The compressor 42 compresses low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure refrigerant gas, which is then released into the coil assembly 41 for rapid expansion and cooling, thereby quickly reducing the temperature of the water in the cylinder 2. This efficient refrigeration system can more effectively reduce water temperature and provide better cooling performance.

[0041] Preferably, a filter 5 is also provided between the cylinder 2 and the heat exchanger 2. The circulation outlet 21 of the cylinder 2 is connected to the inlet pipe of the filter 5, and the outlet of the filter 5 is connected to the first inlet pipe of the heat exchanger 3. The introduction of the filter 5 can effectively filter out impurities and contaminants in the water. This means that the water quality for cold water immersion will remain clean and hygienic, which is beneficial to the athlete's skin health. Clean water can also reduce the need for equipment maintenance and extend the service life of the equipment. The filter 5 is located between the circulation outlet of the cylinder and the first inlet of the heat exchanger, which can effectively prevent impurities from entering the heat exchanger 3. This can reduce the risk of heat exchanger blockage and ensure that the efficiency of heat exchange is not affected. If the heat exchanger 3 is blocked, the effect of cold water immersion will be affected.

[0042] It will decrease significantly.

[0043] Preferably, the circulation outlet 21 of the cylinder 2 is located on the bottom plate 23 of the cylinder 2, and the side wall also includes a second side wall 25. The circulation inlet 22 of the cylinder 2 is located on the second side wall 25 of the cylinder 2. This design helps to reduce water temperature stratification. Normally, colder water accumulates at the bottom, while warmer water floats on top. This stratification leads to uneven water temperature and reduces the cooling effect. Placing the circulation outlet at the bottom can alleviate this problem and make the water temperature more uniform.

[0044] Specifically, evaporator 43 is a finned evaporator. A finned evaporator is a highly efficient refrigeration device with a large surface area, allowing it to absorb heat from the water and transfer it to the refrigerant more quickly. This means that finned evaporators can lower the water temperature more rapidly, providing a more powerful cooling effect. Furthermore, finned evaporators are generally more compact than other types of evaporators, occupying less space. This is advantageous for the design and layout of cold water immersion equipment, especially when deploying equipment in limited spaces, better meeting requirements.

[0045] Specifically, the outer casing assembly 1 includes an outer casing 11 and a bracket 12. A support plate 121 is mounted on the bracket 12, and the coil assembly 41 is mounted on the support plate 11. The support plate 11 provides a stable platform for the coil assembly 41, effectively supporting its weight and preventing it from sagging or shifting due to its own gravity. During equipment operation, especially when the medium inside the coil assembly 41 flows or when it expands or contracts due to temperature changes, the support plate 11 ensures that the coil assembly 41 remains in a fixed position, maintaining its structural integrity and stability, thereby guaranteeing the normal operation of the entire equipment.

[0046] During operation, the heat exchanger 3 is first turned on to achieve continuous water flow, thus enabling dynamic cooling and rapidly cooling the water to 2-3 degrees Celsius. Then, the refrigeration unit is turned on, and the compressor 42 compresses the low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure refrigerant gas. The high-temperature, high-pressure refrigerant gas is then released into the coil assembly 41, causing it to expand and cool rapidly, thereby quickly lowering the water to 0 degrees Celsius and forming an ice state. This efficient refrigeration system can more effectively reduce the water temperature and provide a better cooling effect.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
