Description

Technical Field

[0001] This invention relates to the field of whole-body cryotherapy technology, and in particular to a cryotherapy chamber. Background Technology

[0002] Whole-body cryotherapy refers to the process of placing a person in an extremely low-temperature, fully enclosed insulated chamber for 2 to 3 minutes with minimal skin exposure. The temperature inside the chamber is generally between -80°C and -160°C. This type of insulated chamber can be called a cryotherapy chamber. The principle behind cryotherapy is that the skin is stimulated by low-temperature freezing, which causes the body to release hormones such as dopamine and endorphins, thereby accelerating blood circulation, improving basal metabolism, relieving muscle pain, and increasing skin elasticity.

[0003] Currently, the most advanced cryotherapy chambers use an electrically driven compressor as their cooling source. The main body of the compressor is located on the periphery of the chamber. The refrigerant output from the compressor flows to an evaporator inside the chamber, where it evaporates and cools. Air driven by a circulating fan flows through the evaporator and exchanges heat with it, thus lowering the temperature of the air inside the chamber and achieving cooling.

[0004] In practical applications, cryotherapy chambers operating under heavy loads are used frequently, typically opening 40 to 100 times per day. Each opening introduces a large amount of air containing water vapor, especially in humid summer conditions. For example, in an environment with a temperature of 25°C and a relative humidity of 70%, each cubic meter of air contains 16 grams of water vapor. When this water vapor-containing air enters the chamber, it condenses into frost on the low-temperature circulating fan blades and evaporator. After 4 to 8 openings, the frost on the evaporator blocks the fins, hindering airflow and heat exchange, thus slowing down or even preventing cooling. After 20 to 40 openings, thick frost accumulates on the circulating fan blades, rendering them ineffective and hindering proper cooling.

[0005] In one existing technology, to solve the above problem, users need to control the indoor relative humidity to below 40%, for example, by continuously dehumidifying the room with air conditioning, but this method consumes a lot of energy.

[0006] Another existing technology uses heating to defrost the evaporator. The heat generated raises the temperature of the cryotherapy chamber by over 30°C, and it takes 25 to 30 minutes to cool it back to the original set temperature, which is time-consuming. In environments with high relative humidity, if heating is used to defrost the evaporator, the heating process will take up approximately 30% to 50% of the time, reducing the utilization rate of the cryotherapy chamber. Furthermore, for frost condensing on the circulating fan blades, due to the irregular shape of the fan blades, electric heating wires and other heating methods cannot be used for defrosting. The cryotherapy chamber must be completely shut down, and a handheld hot air blower must be used to defrost the fan blades. After defrosting, it takes more than 30 minutes for the cryotherapy chamber to cool back to the original set temperature, which is also time-consuming and requires frequent defrosting, further reducing the utilization rate of the cryotherapy chamber.

[0007] Therefore, in the existing technology, the method of dehumidifying the room through air conditioning and thus controlling the relative humidity of the room consumes a lot of energy. Using heating to defrost the evaporator and using a blower to blow hot air to defrost the circulating fan blades reduces the utilization rate of the low temperature therapy chamber.

[0031] Beneficial effects of the embodiments of the present invention:

[0032] This invention provides a low-temperature physiotherapy chamber with a defrost collector installed at the air inlet of the air circulation channel. Air entering the chamber must pass through the defrost collector's inlet before entering the air circulation channel, thus exchanging heat with the evaporator to lower the temperature of the air inside the chamber, thereby achieving cooling. When the low-temperature physiotherapy chamber is in cooling mode, the temperature inside the chamber is generally between -80°C and -160°C, resulting in a similar temperature for the defrost collector located inside the chamber. When the chamber door is open, water vapor enters the chamber and, as it passes through the defrost collector's inlet, comes into contact with the extremely low-temperature defrost collector, condensing and cooling within it. Frost condenses on the defrost collector, thus reducing water vapor entering the air circulation channel. This significantly reduces frost buildup on the evaporator and the fan blades of the circulating fan, eliminating the need for air conditioning to dehumidify and control indoor relative humidity, thereby reducing energy consumption. When there is a lot of frost on the defrost collector, it can be directly tapped to remove it. This method is quick and efficient, eliminating the need for heating or using a hot air blower for defrosting. It also eliminates the need to wait for the low-temperature therapy chamber to cool down to its original temperature, increasing the utilization rate of the low-temperature therapy chamber.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of the present invention.

[0057] In order to reduce energy consumption and increase the utilization rate of the cryotherapy chamber, this application provides a cryotherapy chamber, which will be described in detail below.

[0058] In all the accompanying drawings of this application, the structures indicated by dashed lines represent the parts that are obscured from the current view angle. Reference Figure 1 and Figure 2This application provides a low-temperature physiotherapy chamber, comprising: a chamber body 10, with a door (not shown in the figure); an air circulation channel 20, disposed on a first inner wall 11 of the chamber body 10, the air circulation channel 20 having a circulation air inlet 21 and a circulation air outlet 22, both of which are connected to the interior of the chamber body 10; an evaporator 30, disposed within the air circulation channel 20 and located between the circulation air inlet 21 and the circulation air outlet 22; a circulation fan 40, including a fan 41 and a fan blade 42, the fan 41 being disposed on the outer wall of the chamber body 10, the fan blade 42 being disposed within the air circulation channel 20 and located between the circulation air inlet 21 and the circulation air outlet 22, the fan 41 being used to drive the fan blade 42 to rotate; and a defrost collector 50, covering the circulation air inlet 21, the defrost collector 50 having an air inlet hole, through which air can enter the air circulation channel 20.

[0059] In this embodiment, a defrost collector 50 is installed at the air inlet 21 of the air circulation channel 20. Air entering the chamber 10 must pass through the air inlet of the defrost collector 50 before entering the air circulation channel 20, thereby exchanging heat with the evaporator 30 to lower the temperature of the air inside the chamber 10, thus enabling the low-temperature therapy chamber to cool. When the low-temperature therapy chamber is in cooling mode, the temperature inside the chamber 10 is generally between -80°C and -160°C, resulting in a similar temperature for the defrost collector 50 located inside the chamber 10. When the chamber door is open, water vapor enters the chamber 10 and, during its passage through the air inlet of the defrost collector 50, comes into contact with the extremely low-temperature defrost collector 50, and is then collected... Frost condenses on the defrost collector 50, thus reducing the amount of water vapor entering the air circulation channel 20. This significantly reduces the amount of frost condensing on the evaporator 30 and the fan blades 42 of the circulating fan 40, eliminating the need for air conditioning to dehumidify the room and control the relative humidity. This reduces the energy consumption of the air conditioning system and thus lowers energy consumption. When there is a lot of frost condensing on the defrost collector 50, it can be directly tapped to remove the frost. This method is quick and efficient, eliminating the need for heating or using a blower to blow hot air for defrosting. It also eliminates the need to wait for the low-temperature therapy chamber to cool down to its original temperature, thus increasing the utilization rate of the low-temperature therapy chamber.

[0060] In some embodiments, the cabin 10 is a cuboid shape with an internal accommodating space, and the cabin door is located at... Figure 2 On the right side wall of the shown hull 10, the first inner side wall 11 is positioned opposite the hatch.

[0061] In other embodiments, the first inner wall 11 may also be disposed adjacent to the hatch.

[0062] In some embodiments, reference Figure 2The fan blades 42 are positioned in front of the evaporator 30, meaning that the air entering the air circulation channel 20 first passes through the fan blades 42 and then through the evaporator 30.

[0063] In other embodiments, reference is made to... Figure 3 The fan blade 42 can also be set after the evaporator 30, that is, the air entering the air circulation channel 20 first passes through the evaporator 30 and then through the fan blade 42. At this time, the evaporator 30 can also be equivalent to a defrost collector. In other words, there are two defrost collectors before the fan blade 42, which further reduces the frost condensed on the fan blade 42.

[0064] In some embodiments, reference Figure 1 and Figure 2 The cabin 10 has a side cover plate 23 inside, which is parallel to the first inner side wall 11. Two second inner side walls 12 on the cabin 10, which are adjacent to the first inner side wall 11, are connected to the two sides of the side cover plate 23 facing the second inner side wall 12, respectively. The inner top wall 13 of the cabin 10 is connected to the top of the side cover plate 23, and there is a gap between the inner bottom wall 14 of the cabin 10 and the bottom of the side cover plate 23. The side cover plate 23, the first inner side wall 11, and the two second inner side walls 12 form an air circulation channel 20. The side cover plate 23 has an opening 231, which is the air circulation inlet 21 of the air circulation channel 20.

[0065] In an exemplary embodiment, the portions of the two second inner sidewalls 12 located between the side cover plate 23 and the first inner sidewall 11 together with the side cover plate 23 and the first inner sidewall 11 form an air circulation channel 20.

[0066] In this embodiment, the side cover plate 23, the first inner sidewall 11 and the two second inner sidewalls 12 form an air circulation channel 20. The air circulation channel 20 has a large space, so more air enters the air circulation channel 20 to exchange heat with the evaporator 30, which can improve the cooling speed of the low temperature therapy chamber, thereby reducing the waiting time for the low temperature therapy chamber to cool down and further improving the utilization rate of the low temperature therapy chamber.

[0067] In some embodiments, the opening 231 of the side cover 23 is located near the top of the side cover 23.

[0068] In some embodiments, the opening 231 of the side cover plate 23 can be a rectangular opening or an opening of other shapes, such as a circle or an ellipse. This application does not impose specific limitations, as long as the frost collector 50 can cover the opening 231.

[0069] In some embodiments, reference Figure 1 , Figure 2 and Figure 5A suction cup 51 is provided on the side of the defrost collector 50 near the first inner wall 11 of the cabin 10, and the suction cup 51 is attached to the area around the opening 231 on the side cover plate 23; or, the defrost collector 50 is hinged to the side cover plate 23 near the opening 231.

[0070] In an exemplary embodiment, when the defrost collector 50 is hinged to the side cover plate 23 near the opening 231, only one side of the defrost collector 50 is hinged to the side cover plate 23 near the opening 231, so that the defrost collector 50 can be opened.

[0071] In this embodiment, the suction cup 51 of the defrost collector 50 is attached to the area around the opening 231 on the side cover plate 23, making it easier to remove the defrost collector 50 from the side cover plate 23. When there is a lot of frost condensed on the defrost collector 50, the defrost collector 50 can be removed and tapped or blown with a hair dryer to defrost it, thus making defrosting the defrost collector 50 more convenient. The defrost collector 50 can also be hinged to the side cover plate 23 near the opening 231. By pulling open the side of the defrost collector 50 that is not connected to the side cover plate 23, the opening 231 of the defrost collector 50 can be exposed. At this time, the defrost collector 50 can be tapped or blown with a hair dryer to defrost it, thus making defrosting the defrost collector 50 more convenient.

[0072] In some embodiments, the suction cup 51 is a magnetic suction cup, and the side cover plate 23 is a metal cover plate.

[0073] In some embodiments, the defrost collector 50 may be hinged to the side cover 23 near the opening 231 using a hinge.

[0074] In other embodiments, a pin may be used to hinge the defrost collector 50 to the side cover 23 near the opening 231.

[0075] In some embodiments, reference Figure 4 The low-temperature physiotherapy chamber also includes: a purge cover 60; a purge port 232 is provided on the side cover 23 near the evaporator 30, and the purge cover 60 can cover or expose the purge port 232.

[0076] In this embodiment, when the cryogenic therapy chamber has been used for an extended period and a significant amount of frost has accumulated on the evaporator 30, the blow-out cover 60 can be exposed to expose the blow-out port 232, allowing for manual defrosting of the evaporator 30 independently. Since most of the frost forming on the evaporator 30 that blocks the airflow is like cotton wool rather than solidified ice, it can be blown away by a sufficiently strong wind. Therefore, a handheld hairdryer can be used to blow away the frost on the evaporator 30 through the blow-out port 232.

[0077] In some embodiments, a suction cup may be provided on the side of the purge cover 60 near the side cover 23. The purge cover 60 is attached to the position around the purge port 232 on the side cover 23 by the suction cup, so that the purge cover 60 can be removed more easily, the purge port 232 can be exposed more easily, and the evaporator 30 can be manually defrosted more easily.

[0078] In some embodiments, the suction cup of the blow-out cover 60 is a magnetic suction cup, and the side cover 23 is a metal cover.

[0079] In some embodiments, the purge cover 60 may also be hinged to the side cover 23 near the purge port 232, and the purge port 232 can be exposed by pulling open the purge cover 60.

[0080] In some embodiments, a hinge can be used to hinge the purge cover 60 to the side cover 23 near the purge port 232.

[0081] In other embodiments, a pin may be used to hinge the purge cover 60 to the side cover 23 near the purge port 232.

[0082] In some embodiments, the ratio 'a' of the total ventilation cross-sectional area of ​​the defrost collector 50 to the total ventilation cross-sectional area of ​​the evaporator 30 is in the range of 1 ≤ a ≤ 3.

[0083] In an exemplary embodiment, the total ventilation cross-sectional area of ​​the defrost collector 50 refers to the cross-sectional area of ​​all air inlets on the defrost collector 50 that allow air to enter the air circulation channel 20.

[0084] In this embodiment, the ratio 'a' of the total ventilation cross-sectional area of ​​the defrost collector 50 to the total ventilation cross-sectional area of ​​the evaporator 30 is set to the range mentioned above. This allows as much frost as possible to condense on the defrost collector 50, reducing the amount of water vapor entering the air circulation channel 20, thereby further reducing the frost condensing on the evaporator 30 and the fan blades 42.

[0085] In some embodiments, reference Figure 6 The defrost collector 50 includes: a frame 52, multiple fins 53 located inside the frame 52, and multiple support tubes 54; the multiple fins 53 are arranged in parallel and spaced apart, each support tube 54 passes through multiple fins 53, and the multiple support tubes 54 are arranged in parallel and spaced apart; two adjacent fins 53 and two adjacent support tubes 54 form an air inlet.

[0086] In this embodiment, multiple fins 53 are arranged in parallel and spaced apart, and multiple support tubes 54 are arranged in parallel and spaced apart. Two adjacent fins 53 and two adjacent support tubes 54 form an air inlet. Therefore, multiple air inlets are formed on the defrost collector 50 to allow water vapor to pass through, thereby increasing the contact area between water vapor and the defrost collector 50 and reducing the amount of water vapor entering the air circulation channel 20.

[0087] In some embodiments, the spacing between two adjacent fins 53 is the same, and the spacing between two adjacent support tubes 54 is the same, so that the size of multiple air inlets is the same, the defrost collector 50 can more evenly condense the passing water vapor into frost, reduce the water vapor entering the air circulation channel 20, and further reduce the frost on the evaporator 30 and fan blades 42.

[0088] In some embodiments, the frame 52 is a rectangular frame, each fin 53 is arranged along a direction perpendicular to the inner top wall 13 of the cabin 10, and multiple fins 53 are arranged parallel to each other along a direction parallel to the first inner sidewall 11; the support tube 54 is perpendicular to the fins 53, and multiple support tubes 54 are arranged parallel to each other along a direction perpendicular to the inner top wall 13.

[0089] In some embodiments, the thickness T1 of each fin 53 ranges from 0.1mm ≤ T1 ≤ 0.4mm, and the width W1 ranges from 15mm ≤ W1 ≤ 40mm; the distance L1 between two adjacent fins 53 ranges from 2mm ≤ L1 ≤ 8mm. Setting the size of the fins 53 and the distance between two adjacent fins 53 to the above range increases the path of water vapor through the defrost collector 50 and increases the contact area between the air and the defrost collector 50. Therefore, the defrost collector 50 can better condense water vapor in the air into frost, reduce the amount of water vapor entering the air circulation channel 20, and further reduce the frost on the evaporator 30 and the fan blades 42.

[0090] In some embodiments, reference Figure 6 A handle 55 is provided on the side of the defrost collector 50 away from the first inner wall 11 of the compartment 10. Both ends of the handle 55 are connected to the frame 52. By holding the handle 55, the defrost collector 50 can be removed from the side cover plate 23, or by holding the handle 55, the defrost collector 50 can be pulled open.

[0091] In other embodiments, the fins 53 and support tubes 54 of the defrost collector 50 can be replaced with metal mesh. The defrost collector 50 includes a frame and a plurality of metal meshes located inside the frame. The plurality of metal meshes are arranged in parallel and spaced apart, and the mesh openings of the metal meshes are air inlets.

[0092] In this embodiment, air enters the air circulation channel 20 through the mesh of the metal mesh. Water vapor in the air condenses into frost upon contact with the metal mesh. Multiple metal meshes are arranged in parallel and spaced intervals, meaning that air must pass through multiple meshes sequentially to enter the air circulation channel 20. This prolongs the path for water vapor to enter the air and increases the contact area between the water vapor and the defrost collector 50. The defrost collector 50 can better condense water vapor into frost, reducing the amount of water vapor entering the air circulation channel 20, and further reducing frost on the evaporator 30 and fan blades 42.

[0093] In some embodiments, the metal mesh may be stainless steel mesh.

[0094] In some embodiments, the diameter D of the metal wires constituting the metal mesh ranges from 0.3mm ≤ D ≤ 1mm; the size L2 of each mesh opening ranges from 4mm ≤ L2 ≤ 10mm; the number X of the metal mesh ranges from 4 ≤ X ≤ 8; and the spacing L3 between two adjacent metal meshes ranges from 1mm ≤ L3 ≤ 4mm.

[0095] In this embodiment, the diameter D of the metal wire, the size L2 of the mesh, the number of metal meshes X, and the spacing L3 between two adjacent metal meshes are set to the above range. This increases the path of water vapor in the air through the defrost collector 50 and increases the contact area between the water vapor in the air and the defrost collector 50. The defrost collector 50 can better condense the water vapor in the air into frost, reduce the amount of water vapor entering the air circulation channel 20, and further reduce the frost on the evaporator 30 and the fan blades 42.

[0096] In some embodiments, the mesh openings of the metal mesh can be rectangular, and the dimension L2 of each mesh opening includes a length dimension and a width dimension, both of which are in the range of 4mm≤L2≤10mm, wherein the width dimension is always less than the length dimension.

[0097] In other embodiments, the mesh openings of the metal mesh can also be square, in which case the side length of the mesh openings ranges from 4mm ≤ L2 ≤ 10mm.

[0098] In some embodiments, reference Figure 7 and Figure 8 The low-temperature physiotherapy chamber also includes a blower 70. The blower 70 is located on the top of the chamber 10. The blower 70 includes a blower air inlet 71, a blower air outlet 72 and a blower air nozzle 73 located inside the chamber 10. The blower air outlet 72 is connected to the blower air nozzle 73, and the blower air nozzle 73 faces the evaporator 30.

[0099] In this embodiment, the frost on the evaporator 30 can be automatically removed. The blower nozzle 73 faces the evaporator 30 and can blow air onto the evaporator 30 to remove the frost, making defrosting the evaporator 30 more convenient and reducing labor costs. Furthermore, the blower inlet 71, blower outlet 72, and blower nozzle 73 are all located inside the chamber 10, which avoids the intake of hot and humid air from the outside and prevents the hot and humid air from condensing into frost on the evaporator 30.

[0100] In some embodiments, reference Figure 7 and Figure 8Blower 70 is a high-pressure vortex blower with a power of 500W and an air volume of 105m³. 3 / h, wind pressure is 190Kpa; blower outlet 73 is a duckbill outlet, and the duckbill outlet is connected to blower outlet 72 by metal bellows 74; a rotary motor 75 is installed on the outside of the chamber 10, and the rotary motor 75 is connected to the duckbill outlet.
