Description

Technical Field

[0001] The present invention relates to the technical field of ice bath tubs, and in particular to an ice bath rehabilitation intelligent constant temperature bath tub. Background Art

[0002] An ice bathtub is a smart, temperature-controlled bathtub that provides a professional ice bath experience. It can be used for muscle recovery and relaxation after exercise. When immersed in ice water, the low temperature causes blood vessels to constrict, effectively reducing swelling and lowering muscle temperature. This in turn slows metabolic reactions that damage cells, significantly alleviating muscle soreness and inflammation. Furthermore, ice baths slow nerve transmission, allowing tense muscles to relax. Studies have shown that ice baths can significantly reduce muscle soreness and cell damage after sustained exercise, and aid in the recovery of explosive power, significantly benefiting subsequent athletic performance.

[0003] Existing ice bathtub machines, such as hot spring bathtub machines, have two main structures: one is that the cooling and hot water system main unit and the hot spring bathtub are two separate parts. When in use, the customer connects the two parts with a hose, allowing water to circulate to cool and heat the hot spring bathtub water; the other is that the manufacturer directly embeds the cooling and hot water system main unit on the outside of the hot spring bathtub and connects the water channel with PVC pipes, realizing a nominally all-in-one machine.

[0004] In actual use, existing ice bathtubs need to connect the unit and the bathtub through pipes such as hoses. At the same time, the pipes in the unit need to pass through multiple components such as the purifier, evaporator (or titanium cannon), and ozone tube. This results in excessively long pipes and complex connection structures, which in turn leads to large water flow resistance, reduced water flow, low system heat exchange efficiency, easy frost on the evaporator (or titanium cannon) and inability to reach lower temperatures such as zero degrees, a high water pump failure rate, high noise, easy air in the pipes that can damage the water pump, and a complex structure that is inconvenient to disassemble and repair. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent constant-temperature bathtub for ice bath rehabilitation, which solves the technical problems of existing ice bathtubs, such as large water flow resistance, low heat exchange efficiency, easy frost on the evaporator and difficulty in reaching zero temperature, high water pump failure rate, loud noise, air accumulation in the pipes, and difficulty in disassembly and maintenance, caused by the long and complex pipe connection between the unit and the bathtub.

[0006] In order to solve the above technical problems, the technical solutions of the present invention are as follows: The present invention provides an ice bath rehabilitation intelligent constant temperature bathtub, comprising a water circulation system, an air conditioning system and a controller; the water circulation system comprises a bathtub and a water pump; a partition is provided on one side of the bathtub and is connected thereto; the water pump is arranged on one side of the bathtub and is connected to the partition, and is used to drive water circulation inside and outside the partition; the air conditioning system comprises a temperature control pipeline, a heat exchange device and a compressor; the temperature control pipeline is installed in the partition and is connected to the heat exchange device; the compressor is connected to the heat exchange device and the temperature control pipeline via a circulation reversing valve, and is used to directly cool or heat the water in the partition via the temperature control pipeline; the controller is at least electrically connected to the air conditioning system.

[0007] Furthermore, the temperature regulating pipeline is arranged vertically, the output end of the water pump is arranged at the bottom of the partition, and the water flow direction in the partition is water inlet at the bottom and water outlet at the top, so that the water flow fully disturbs the temperature regulating pipeline to suppress frost and improve heat exchange efficiency.

[0008] Furthermore, the temperature regulating pipeline adopts a titanium tube.

[0009] Furthermore, the heat exchange device includes a heat exchanger and a fan that are arranged relatively to each other.

[0010] Furthermore, the air conditioning system also includes a temperature sensor, which is arranged at the outlet of the partition and is used to measure the water temperature and feed back to the controller.

[0011] Furthermore, the air conditioning system also includes a sterilization device, which is arranged in the partition.

[0012] Furthermore, the sterilization device is an ozone sterilization device, and the air-conditioning system also includes an ozone generator connected to the ozone device.

[0013] Furthermore, the water circulation system also includes a filtering device, which is installed at the water inlet of the water pump.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention arranges the water pump and the temperature-regulating pipe (titanium tube) on one side of the bathtub and simplifies the pipe connection structure of the air-conditioning system, thereby reducing the operation, length and structure of the pipe connection, thereby reducing water flow resistance, increasing the water circulation flow and the system heat exchange efficiency (increased by more than 30%), thereby making the temperature-regulating pipe (titanium tube) less likely to frost and reach a lower temperature such as zero degrees, reducing the failure rate and noise of the water pump, reducing the presence of air in the pipe, and not easily damaging the water pump. The simplified structure facilitates later disassembly and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0019] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0020] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0021] This embodiment provides an ice bath rehabilitation intelligent constant temperature bathtub, please refer to Figure 1-5 As shown, it includes a water circulation system, an air-conditioning system and a controller; the water circulation system includes a bathtub 10 and a water pump 20; a partition 11 is provided on one side of the bathtub 10 and is connected thereto, and the water pump 20 is arranged on one side of the bathtub 10 and is connected to the partition 11, for driving the water circulation inside and outside the partition 11; the air-conditioning system includes a temperature control pipeline 30, a heat exchange device 40 and a compressor 50; the temperature control pipeline 30 is installed in the partition 11 and is connected to the heat exchange device 40; the compressor 50 is connected to the heat exchange device 40 and the temperature control pipeline 30 through a circulation reversing valve, for directly cooling or heating the water in the partition 11 through the temperature control pipeline 30; the controller is at least electrically connected to the air-conditioning system.

[0022] Specifically, in the water circulation system, a partition 11 is provided on one side of the bathtub 10, and the partition 11 is connected to the bathtub 10 to form an independent water circulation channel; a water pump 20 drives the water circulation inside and outside the partition 11 (the water is pumped into the partition 11 by the water pump 20, and then flows out to the bathtub 10 through the partition (upper) outlet), avoiding direct impact on the user and improving comfort; among them, the circulating water flow ensures that the water temperature in the bathtub 10 is evenly distributed to avoid local overheating or overcooling. In the air conditioning system, compressor 50 is the heart of the refrigerant circulation. The high-temperature, high-pressure gas generated enters heat exchanger 40, where it is dissipated by external fan 42. The refrigerant is cooled to a high-pressure liquid, which is then throttled through a capillary tube to a low-temperature, low-pressure gas-liquid. The temperature-regulating pipe 30 exchanges heat with the water in interlayer 11, turning the refrigerant into a low-temperature gas. This gas is then drawn into compressor 50, compressed into a high-temperature gas, and discharged into heat exchanger 40 (condenser) for further heat exchange. A four-way valve is added to the air conditioning system to reverse the refrigerant circulation system, allowing the high-temperature, high-pressure gas discharged from compressor 50 to enter the titanium tube or condenser, thereby achieving water cooling or heating. Furthermore, in the water circulation system, the low-temperature gas-liquid entering the temperature-regulating pipe 30 can reach a temperature of approximately -15°C and requires heat exchange with water to prevent frost from forming. The water pump 20 is used to increase the circulation of the low-temperature water, prevent frost from forming in the temperature-regulating pipe 30, and quickly cool the water in the bathtub 10. Specifically, because the temperature-regulating pipe 30, such as a titanium tube, is directly placed on one side of the bathing pool, the water pump 20 has no pipe resistance and the water circulation is increased, which not only increases the cooling speed by more than 30%, but also allows the original lowest low-temperature water of 2 degrees Celsius to be reduced to 0 degrees Celsius; in addition, the water pump can be controlled independently, and the two systems can also be controlled by a controller to operate in coordination, so that the bathtub water reaches a predetermined water temperature and maintains a constant water temperature.

[0023] In this embodiment, the temperature control pipeline 30 is arranged vertically, and the output end of the water pump 20 is arranged at the bottom of the partition 11. The water flow direction in the partition 11 is water inlet at the bottom and water outlet at the top, so that the water flow fully disturbs the temperature control pipeline 30 to suppress frost and improve heat exchange efficiency.

[0024] Specifically, the water pump 20 can be arranged in the partition on one side of the bathtub 10, with its input end (the port can be opened on the partition) connected to the bathtub 10, and its output end connected to the bottom of the partition 11; in addition, the water pump can also be directly arranged at the bottom of the partition, and its input port is sealed and passed through the bottom of the partition (or through the water inlet pipe set at the bottom of the partition) to communicate with the bathtub 10; wherein, the water flow direction in the partition 11 is water inlet from the bottom and water outlet from the top. Preferably, the water flow direction is water inlet from the bottom of the titanium tube and water outlet from the top of the titanium tube, which achieves maximum water flow disturbance, enhances the contact area and mixing efficiency between the fluid and the outer wall of the titanium tube, so that the titanium tube is not easy to frost at low temperatures (the key to reducing the original minimum low-temperature water of 2 degrees to 0 degrees Celsius), and at the same time increases the heat exchange efficiency (increased by more than 30%).

[0025] In this embodiment, the temperature regulating pipeline 30 is made of a titanium tube.

[0026] Specifically, titanium tubes are used to replace the evaporator of the air-conditioning system. With their advantages of strong corrosion resistance, high heat exchange efficiency, high strength and light weight, good anti-fouling performance, safety and non-toxicity, and good low-temperature performance, they can not only resist the erosion of chemicals in the bathtub water, quickly and accurately control the temperature, but also be easy to install and maintain, reduce dirt accumulation and cleaning costs, and protect the health of users. They can operate stably even in low-temperature environments, significantly improving the reliability, safety and user experience of the system.

[0027] In this embodiment, the heat exchange device 40 includes a heat exchanger 41 and a fan 42 that are arranged opposite to each other.

[0028] Specifically, the heat exchange device 40 in the air-conditioning system adopts a heat exchanger 41 and a fan 42 arranged relatively to each other, and forms forced convection through the fan 42 to enhance the heat exchange efficiency, thereby enabling rapid cooling or heating and precise control of water temperature.

[0029] In this embodiment, the air conditioning system further includes a temperature sensor, which is disposed at the outlet of the partition 11 and is used to measure the water temperature and feed back the temperature to the controller.

[0030] Specifically, a temperature sensor is installed at the exit of compartment 11 to accurately monitor water temperature changes in real time, converting the signal into an electrical or digital signal and transmitting it to the controller. The controller compares the signal with a preset temperature value and controls the operation of the air conditioning system. When the water temperature falls below the set value, heating is activated; when it exceeds the set value, cooling is controlled or heating is stopped. This ensures that the water temperature in bathtub 10 is always maintained within the set constant temperature range, providing users with a stable and comfortable water temperature environment and meeting various usage needs such as ice bath rehabilitation.

[0031] In this embodiment, the air conditioning system further includes a sterilization device, which is disposed in the partition 11. The sterilization device is an ozone sterilization device, and the air conditioning system further includes an ozone generator 60 connected to the ozone device.

[0032] Specifically, by integrating the ozone sterilization device into the water circulation system's barrier 11 and operating it in conjunction with the ozone generator 60, the ice bath rehabilitation constant temperature bathtub 10 achieves intelligent sterilization. Ozone sterilization technology offers the advantages of broad-spectrum and high-efficiency sterilization, eliminating pathogens in the water while avoiding the risk of residual chemical disinfectants. Its decomposition product, oxygen, ensures user safety.

[0033] In this embodiment, the water circulation system further includes a filtering device, which is installed at the water inlet of the water pump 20 .

[0034] Specifically, a filter device is installed at the partition of the water inlet of the water pump 20 to purify impurities in the water of the bathtub 10.

[0035] Working principle: 1. The present invention can be divided into two systems: an air conditioning system (providing cold and heat sources) and a water circulation system (cold and hot water circulate inside the bathtub to achieve a constant temperature); 2. This invention replaces the evaporator (or titanium cannon) in the air conditioning system with a titanium tube and places it inside the bathtub to cool or heat the water; 3. The titanium tube (also known as the temperature control pipe 30) is placed on one side of the bathtub. The water flows in from the bottom of the titanium tube and out from the top of the titanium tube, achieving maximum water flow disturbance and making it difficult for the outer wall of the titanium tube to frost at low temperatures. This is the key to achieving a water temperature of 0 degrees. 4. The water pump eliminates the original water pipe flow path (which originally had to pass through the purifier, titanium cannon, ozone tube and connecting hose, etc.), the water flow rate has increased by more than 30%, and the water pump has also achieved silent operation and zero installation failure rate.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
