Description

Technical Field

[0001] This invention relates to the field of ice-water bath technology, and in particular to an ice-water bath and a method for controlling the ice-water ratio. Background Technology

[0002] An ice-water bath is a temperature control device widely used in scientific experiments, industrial production, and medical fields. It is primarily used for precise temperature control of samples or reaction systems, achieving rapid cooling and stable temperature control through the low-temperature environment of an ice-water mixture. Ice-water baths are mostly made of stainless steel, which has good thermal conductivity and corrosion resistance. They are commonly rectangular or cylindrical in shape and come in various sizes, ranging from several liters to tens of liters, to meet different experimental or production needs.

[0003] The ice-water bath is equipped with a temperature sensor that monitors the water temperature in real time and sends the signal back to the control system. The control system adjusts the operating power of the refrigeration system or stops it based on the difference between the set temperature and the actual temperature to precisely control the water temperature.

[0004] The cooling system of an ice water bath controls the temperature by starting and stopping the compressor. When the temperature reaches the set value, the compressor stops working, and the temperature inside the bath may gradually rise due to heat transfer from the surrounding environment. When the temperature rises to a certain level, the compressor restarts to cool the tub. This frequent start-stop cycle causes periodic temperature fluctuations. Summary of the Invention

[0005] The purpose of this invention is to address the problem in the background art where frequent start-stop of the compressor causes temperature fluctuations that affect experiments, and to propose an ice-water bath apparatus and its ice-water ratio control method.

[0006] On one hand, the present invention proposes an ice water bath device, including an ice bath device body, wherein heat dissipation holes are provided on the side of the ice bath device body, a control panel is fixedly installed on the front of the ice bath device body, and a support beam is fixedly installed on the top of the ice bath device body.

[0007] The ice bath assembly includes an ice bath box, a reflux box, a micro peristaltic pump, and an overflow box. The ice bath box is fixedly installed on the top of the ice bath device body. The reflux box is fixedly connected to the side of the ice bath box. The micro peristaltic pump is fixedly installed at the connection between the reflux box and the ice bath box. The overflow box is fixedly installed on the side of the ice bath box away from the reflux box. The overflow box and the reflux box are interconnected.

[0008] The temperature difference flow control assembly includes a bimetallic temperature coil spring, a deflection assembly, a sliding switch, and an electromagnetic pressure valve. Two bimetallic temperature coil springs are provided, one of which is located at the top of the ice bath box, and half of the other bimetallic temperature coil spring is located inside the ice bath box. A deflection assembly is provided between the two bimetallic temperature coil springs. Sliding switches are fixedly installed on the sides of the support block at both ends of the deflection assembly.

A micro peristaltic pump is fixedly installed at the end of the electromagnetic pressure valve.

[0009] Optionally, a partition plate is fixedly installed between the ice bath box and the overflow box. The top of the partition plate has an overflow port.

[0010] Optionally, a compressor is fixedly installed inside the ice bath device body and at the bottom of the reflux box. The compressor is connected to the reflux conduit via a copper sheet. The reflux conduit is a U-shaped copper pipe, and ice water flows inside the reflux conduit.

[0011] Optionally, the ice bath box is fixedly installed with a placement fixing box for placing reaction flasks. Multiple placement fixing boxes are provided and are distributed at equal intervals along a straight line along the ice bath box. There is a gap between the placement fixing boxes and the ice bath box.

[0012] Optionally, the deflection assembly further includes a support block, a slider, a deflecting element, and a sliding plate. The support block is fixedly installed on the side of the ice bath box. Circular plates are fixedly installed on both the upper and lower sides of the support block. The slider slides on the arc surface of the circular plates. The slider is located on the side of the bimetallic temperature coil spring near the support block. The slider is fixedly connected to the deflecting element via an elastic rope. The end of the deflecting element is slidably connected to the sliding plate. The top of the sliding plate contacts a sliding switch.

[0013] Optionally, an extension plate is fixedly installed at the end of the bimetallic temperature coil spring, and a clamping plate is fixedly installed on the side of the slider near the bimetallic temperature coil spring. The clamping plate has a U-shaped structure, and the extension plate is located inside the opening of the clamping plate.

[0014] Optionally, the deflector adopts a cross-shaped structure. Initially, the vertical part of the deflector is perpendicular to the ground, and the horizontal part of the deflector is parallel to the ground. The side of the support block is provided with a sliding groove, and the slide plate slides up and down along the sliding groove on the side of the support block.

[0015] Optionally, a mixing assembly is provided between the ice bath box and the reflux box. The mixing assembly includes a water pump pipe, a support plate, a turbine, and mixing blades. The two ends of the water pump pipe are fixedly connected to the ice bath box and the reflux box, respectively. An electromagnetic pressure valve is fixedly installed at the end of the water pump pipe. The support plate is fixedly installed inside the water pump pipe. The turbine is fixedly installed in the middle of the support plate. A mixing blade is coaxially connected to the center of the turbine.

[0016] Optionally, multiple water pumping pipes are provided, and the blades of the turbines rotating inside two adjacent water pumping pipes are oriented counterclockwise and clockwise, respectively. The mixing and stirring blades extend into the interior of the ice bath box, and the water pumping pipes are misaligned with the placement and fixing box.

[0017] On the other hand, the present invention proposes a method for adjusting the ice-water ratio, applied to the aforementioned ice-water bath apparatus, the steps of which are as follows:

[0018] S1, Ice water ice bath: Place the experimental reaction flask in the placement box, adjust the cooling temperature of the compressor through the control panel, use the compressor to lower the water temperature, and after the ice water temperature reaches the set value, add the ice water into the ice bath box to give the reaction flask placed in the placement box an ice bath.

[0019] S2. Replacing the ice water: As the water in the ice bath box is affected by the room temperature, the temperature of the ice water gradually rises. The ice water in the return box is pumped into the ice bath box through a micro peristaltic pump. The ice water in the ice bath box is constantly replaced. The ice water enters the overflow box and then flows back to the return box. The compressor cools the water in the return box. The water in the ice bath box is constantly replaced to prevent the temperature of the ice water in the ice bath box from rising.

[0020] S3. Temperature difference detection: Two bimetallic temperature coil springs are set up. One detects the room temperature and the other detects the temperature of the ice water in the ice bath box. The two bimetallic temperature coil springs have different deflection angles, so that the deflection component deflects. The greater the temperature difference between the room temperature and the temperature of the ice water in the ice bath box, the greater the deflection angle of the deflection component.

[0021] S4. Flow rate control: The greater the deflection angle of the deflector, the greater the upward movement of the slide plate. By changing the position of the sliding switch by moving the slide plate upward, the water flow of the electromagnetic pressure valve can be adjusted. The speed of changing ice water can be adjusted by the temperature difference, thereby stabilizing the temperature of the reaction flask.

[0022] S5. Ice-water mixing: When changing the ice water, the ice water flows through the pump pipe. The turbine inside the pump pipe rotates due to the impact of the water, which causes the mixing blades to rotate to accelerate the mixing of ice water in the ice bath box. At the same time, the blades of the turbines rotating inside the two adjacent pump pipes rotate in different directions. Therefore, the two adjacent mixing blades rotate in different directions, which further improves the mixing efficiency.

[0023] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0024] This invention uses a miniature peristaltic pump to draw ice water from the reflux box to replace the water in the ice bath box. When the ice bath box overflows, the water flows into the overflow box. The water in the overflow box flows back into the reflux box through the reflux conduit. The compressor cools the refluxed water again, so that the newly generated ice water continuously replaces the original ice water, thereby controlling the water temperature in the reflux box to be stable and reducing temperature fluctuations. The compressor operates continuously to avoid temperature fluctuations caused by frequent compressor start-stop, which would affect the experiment. At the same time, the continuous flow of ice water prevents freezing.

[0025] Furthermore, by measuring the room temperature and the initial temperature of the ice water in the ice bath box using two bimetallic temperature coil springs, the temperature difference can be determined to determine the rate of temperature loss. By utilizing the different deflection angles of the two bimetallic temperature coil springs, the deflector can be deflected, causing the slide plate to move upward and change the position of the sliding switch, thereby adjusting the water flow of the electromagnetic pressure valve. With the rate of temperature loss fixed, the rate of replenishing and replacing ice water can be adjusted to stabilize the temperature of the ice water in the ice bath box.

[0026] Furthermore, when replacing the ice water, the ice water flows through the pump pipe, and the turbine inside the pump pipe rotates due to the impact of the water, causing the mixing blades to rotate to accelerate the mixing of ice water in the ice bath box. At the same time, the blades of the turbines rotating inside the two adjacent pump pipes rotate in different directions, so the two adjacent mixing blades rotate in different directions, further improving the mixing efficiency.

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0038] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and 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. Example

[0041] This embodiment proposes an ice-water bath device, such as... Figure 1 As shown, the device includes an ice bath body 1, a heat dissipation hole 2 on the side of the ice bath body 1, a control panel 3 fixedly installed on the front of the ice bath body 1, and a support beam 5 fixedly installed on the top of the ice bath body 1.

[0042] like Figure 2 and Figure 3 As shown, the ice bath device body 1 is equipped with an ice bath assembly 4, including an ice bath box 41, a reflux box 42, a micro peristaltic pump 43, and an overflow box 44. The ice bath box 41 is fixedly installed on the top of the ice bath device body 1. The reflux box 42 is fixedly connected to the side of the ice bath box 41. The micro peristaltic pump 43 is fixedly installed at the connection between the reflux box 42 and the ice bath box 41. The overflow box 44 is fixedly installed on the side of the ice bath box 41 away from the reflux box 42. The overflow box 44 and the reflux box 42 are interconnected.

[0043] A compressor 46 is fixedly installed inside the ice bath device body 1 and at the bottom of the return box 42. The compressor 46 cools the water in the return box 42 and uses a micro peristaltic pump 43 to pump water into the return box 42 to replace the water inside the ice bath box 41.

[0044] A partition plate is fixedly installed between the ice bath box 41 and the overflow box 44. The top of the partition plate has an overflow port. The bottom height of the overflow box 44 is higher than the top height of the return box 42. A return conduit 45 is fixedly installed between the overflow box 44 and the return box 42. The return conduit 45 is inclined. A cooling box is fixedly installed inside the ice bath box 41. The center of the bimetallic temperature coil spring 61 is fixedly connected to the cooling box. The cooling box separates the bimetallic temperature coil spring 61 from the ice water inside the ice bath box 41.

[0045] As the micro peristaltic pump 43 continuously pumps water from the return box 42 into the ice bath box 41, the water in the ice bath box 41 overflows and flows into the overflow box 44 from the overflow port. Since the bottom height of the overflow box 44 is higher than the top height of the return box 42, the water in the overflow box 44 will flow into the return box 42 from the return pipe 45 to circulate and continuously replace the water in the ice bath box 41 to avoid excessive water temperature fluctuations.

[0046] A compressor 46 is fixedly installed inside the main body 1 of the ice bath device and at the bottom of the reflux box 42. The compressor 46 is connected to the reflux conduit 45 via a copper plate. The reflux conduit 45 is a U-shaped copper tube, and ice water flows inside the reflux conduit 45. The compressor 46 uses the copper plate to contact the reflux conduit 45 to cool the water inside. Because the reflux conduit 45 is long and thin, it is sufficient to cool the water inside to the cooling temperature of the compressor 46.

[0047] In this embodiment, a miniature peristaltic pump 43 draws ice water from the return box 42 to replace the water in the ice bath box 41. The water in the ice bath box 41 overflows into the overflow box 44, and the water in the overflow box 44 flows back into the return box 42 through the return conduit 45. The compressor 46 cools the returned water again, so that the newly generated ice water continuously replaces the original ice water, thereby controlling the water temperature in the return box 42 to be stable and reducing temperature fluctuations. The compressor 46 operates continuously to avoid the frequent start and stop of the compressor 46 causing temperature fluctuations that affect the experiment. Example

[0048] Based on Example 1, this example proposes an ice-water bath device, such as... Figure 4 and Figure 5 As shown, a temperature difference flow control component 6 is provided on the side of the ice bath box 41. The temperature difference flow control component 6 includes a bimetallic temperature coil spring 61, a deflection component, a sliding switch 69, and an electromagnetic pressure valve 610. Two bimetallic temperature coil springs 61 are provided. One bimetallic temperature coil spring 61 is located on the top of the ice bath box 41, and half of the other bimetallic temperature coil spring 61 is located inside the ice bath box 41. A deflection component is provided between the two bimetallic temperature coil springs 61. Sliding switches 69 are fixedly installed on the side of the support block 63 at the left and right ends of the deflection component. The electromagnetic pressure valve 610 is located at the connection between the ice bath box 41 and the return box 42. The sliding switch 69 is electrically connected to the electromagnetic pressure valve 610. A micro peristaltic pump 43 is fixedly installed at the end of the electromagnetic pressure valve 610.

[0049] like Figure 6 As shown, the deflection assembly also includes a support block 63, a slider 64, a deflector 66, and a slide plate 67. The support block 63 is fixedly installed on the side of the ice bath box 41. Circular plates are fixedly installed on both the upper and lower sides of the support block 63. The slider 64 slides on the arc surface of the circular plate. The slider 64 is located on the side of the bimetallic temperature coil spring 61 near the support block 63. The slider 64 is fixedly connected to the deflector 66 by an elastic rope. The end of the deflector 66 is slidably connected to the slide plate 67. The top of the slide plate 67 contacts the slide switch 69.

[0050] The deflector 66 adopts a cross-shaped structure. Initially, the vertical part of the deflector 66 is perpendicular to the ground, and the horizontal part of the deflector 66 is parallel to the ground. The side of the support block 63 is provided with a groove 68, and the slide plate 67 slides up and down along the groove 68 on the side of the support block 63.

[0051] Two bimetallic temperature coil springs 61 measure the room temperature and the initial temperature of the ice water in the ice bath box 41 to measure the temperature difference. The different deflection angles of the two bimetallic temperature coil springs 61 cause the deflector 66 to deflect. The greater the temperature difference between the room temperature and the ice water temperature inside the ice bath box 41, the greater the deflection angle of the deflector 66, and the greater the upward movement of the slide plate 67. This upward movement of the slide plate 67 changes the position of the sliding switch 69, thereby adjusting the water flow of the electromagnetic pressure valve 610. Since the slide plate 67 is not connected to the sliding switch 69, once the slide plate 67 has moved the sliding switch 69 upward, it cannot move downward. The sliding switch 69 needs to be manually reset. Therefore, the bimetallic temperature coil springs 61 do not need to adjust the electromagnetic pressure valve 610 again during the operation of the ice bath device.

[0052] The rate of ice water replacement is adjusted by utilizing the temperature difference to stabilize the temperature of the reaction flask. Based on the temperature difference between room temperature and the required ice water temperature, the rate of ice water replacement at electromagnetic pressure valve 610 is adjusted to stabilize the ice water temperature within ice bath 41.

[0053] A temperature sensor is fixedly installed inside the ice bath box 41. The temperature sensor is electrically connected to the micro peristaltic pump 43 through the controller. The temperature sensor works together with two bimetallic temperature coil springs 61 to further improve the stability of the ice water temperature inside the ice bath box 41.

[0054] An extension plate 62 is fixedly mounted on the end of the bimetallic temperature coil spring 61. A clamping plate 65 is fixedly mounted on the side of the slider 64 near the bimetallic temperature coil spring 61. The clamping plate 65 has a U-shaped structure, and the extension plate 62 is located in the opening of the clamping plate 65. The slider 64 slides along the arc surface of the circular plate on the support block 63, and the clamping plate 65 prevents the extension plate 62 from being jammed during rotation.

[0055] In this embodiment, two bimetallic temperature coil springs 61 are used to measure the room temperature and the initial temperature of the ice water in the ice bath box 41 to measure the temperature difference, thereby determining the rate of temperature loss. By utilizing the different deflection angles of the two bimetallic temperature coil springs 61, the deflection element 66 is deflected. The greater the temperature difference between the room temperature and the temperature of the ice water inside the ice bath box 41, the greater the deflection angle of the deflection element 66, and the greater the upward movement distance of the slide plate 67. By using the upward movement of the slide plate 67 to change the position of the sliding switch 69, the water flow of the electromagnetic pressure valve 610 is adjusted. With the temperature loss rate fixed, the speed of replenishing and replacing ice water can be adjusted to stabilize the temperature of the ice water in the ice bath box 41. Example

[0056] Based on the above embodiment 1 or embodiment 2, this embodiment proposes an ice-water bath device, such as... Figure 7 and Figure 8As shown, a mixing assembly 7 is provided between the ice bath box 41 and the return box 42. The mixing assembly 7 includes a water pump pipe 71, a support plate 72, a turbine 73, and a mixing blade 74. The two ends of the water pump pipe 71 are fixedly connected to the ice bath box 41 and the return box 42, respectively. An electromagnetic pressure valve 610 is fixedly installed at the end of the water pump pipe 71. The support plate 72 is fixedly installed inside the water pump pipe 71. The turbine 73 is fixedly installed in the middle of the support plate 72. The mixing blade 74 is coaxially connected to the center of the turbine 73.

[0057] Ice water enters the water pumping pipe 71, and the turbine 73 inside the water pumping pipe 71 rotates due to the impact force of the water. The turbine 73 drives the mixing and stirring blade 74 to rotate, so as to mix and stir the ice water entering the ice bath box 41, making the ice water in the ice bath box 41 uniform in temperature.

[0058] Multiple water pumping pipes 71 are provided. The blades of the turbines 73 rotating inside two adjacent water pumping pipes 71 are oriented counterclockwise and clockwise, respectively. The mixing and stirring blades 74 extend into the interior of the ice bath box 41. The water pumping pipes 71 are misaligned with the fixed box 47.

[0059] Since the blades of the two adjacent turbines 73 are in opposite directions, the two adjacent mixing blades 74 rotate in different directions, causing the ice water in the ice bath box 41 to convect and impact, further improving the mixing efficiency.

[0060] In this embodiment, when replacing the ice water, the ice water flows through the water pumping pipe 71. The turbine 73 inside the water pumping pipe 71 rotates due to the impact of the water, causing the mixing and stirring blades 74 to rotate to accelerate the mixing of ice water in the ice bath box 41. At the same time, the blades of the turbines 73 rotating inside the two adjacent water pumping pipes 71 rotate in different directions. Therefore, the two adjacent mixing and stirring blades 74 rotate in different directions, further improving the mixing efficiency.

[0061] This invention proposes a method for adjusting the ice-water ratio, applied to the aforementioned ice-water bath apparatus, the steps of which are as follows:

[0062] S1, Ice water ice bath: Place the experimental reaction bottle in the placement and fixing box 47, adjust the cooling temperature of the compressor 46 through the control panel 3, use the compressor 46 to lower the water temperature, and after the ice water temperature reaches the set value, add the ice water into the ice bath box 41 to use the ice water to give the reaction bottle placed in the placement and fixing box 47 an ice bath.

[0063] S2. Replacing the ice water: As the water in the ice bath box 41 is affected by the room temperature, the temperature of the ice water gradually rises. The micro peristaltic pump 43 draws the ice water in the return box 42 into the ice bath box 41, continuously replacing the ice water in the ice bath box 41. The ice water enters the overflow box 44 and then flows back into the return box 42. The compressor 46 cools the water in the return box 42 and continuously replaces the water in the ice bath box 41 to prevent the temperature of the ice water in the ice bath box 41 from rising.

[0064] S3. Temperature difference detection: Two bimetallic temperature coil springs 61 are set up. One detects the room temperature and the other detects the temperature of the ice water in the ice bath box 41. The two bimetallic temperature coil springs 61 deflect at different angles so that the deflecting element 66 deflects. The greater the temperature difference between the room temperature and the temperature of the ice water in the ice bath box 41, the greater the deflection angle of the deflecting element 66.

[0065] S4. Flow rate control: The greater the deflection angle of the deflector 66, the greater the upward movement of the slide plate 67. The upward movement of the slide plate 67 changes the position of the sliding switch 69, thereby adjusting the water flow of the electromagnetic pressure valve 610. The speed of changing ice water is adjusted by the temperature difference, thereby stabilizing the temperature of the reaction flask.

[0066] S5. Ice-water mixing: When changing ice water, ice water flows through the water pumping pipe 71. The turbine 73 inside the water pumping pipe 71 rotates due to the impact of the water, causing the mixing and stirring blades 74 to rotate to accelerate the mixing of ice water in the ice bath box 41. At the same time, the blades of the turbines 73 rotating inside the two adjacent water pumping pipes 71 rotate in different directions. Therefore, the two adjacent mixing and stirring blades 74 rotate in different directions, further improving the mixing efficiency.

[0067] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

The mixing and stirring blades (74) extend into the interior of the ice bath box (41). The water pumping pipes (71) are misaligned with the placement and fixing box (47).

7. A method for adjusting the ice-water ratio, applied to the ice-water bath apparatus described in claim 6, comprising the following steps: S1, Ice water ice bath: Place the experimental reaction bottle in the placement fixing box (47), adjust the cooling temperature of the compressor (46) through the control panel (3), use the compressor (46) to reduce the temperature of the water, and after the ice water temperature reaches the set value, add the ice water into the ice bath box (41) and use the ice water to give the reaction bottle placed in the placement fixing box (47) an ice bath. S2. Replacing the ice water: As the water in the ice bath box (41) is affected by the room temperature, the temperature of the ice water gradually rises. The ice water in the return box (42) is pumped into the ice bath box (41) by the micro peristaltic pump (43), and the ice water in the ice bath box (41) is constantly replaced. The ice water enters the overflow box (44) and then flows back to the return box (42). The compressor (46) cools the water in the return box (42) and the water in the ice bath box (41) is constantly replaced to prevent the temperature of the ice water in the ice bath box (41) from rising. S3. Temperature difference detection: The upper bimetallic temperature coil spring detects the room temperature, and the lower bimetallic temperature coil spring detects the temperature of the ice water inside the ice bath box (41). By utilizing the different deflection angles of the two bimetallic temperature coil springs (61), the deflection component (66) is deflected. The greater the temperature difference between the room temperature and the temperature of the ice water inside the ice bath box (41), the greater the deflection angle of the deflection component (66). S4. Flow rate control: The greater the deflection angle of the deflector (66), the greater the upward movement distance of the slide plate (67). By moving the slide plate (67) upward, the position of the sliding switch (69) is changed, thereby adjusting the water flow of the electromagnetic pressure valve (610). The speed of changing ice water is adjusted by the size of the temperature difference, so that the temperature of the reaction bottle is stabilized. S5, Ice-water mixing: When changing ice water, ice water flows through the water pump (71). The turbine (73) inside the water pump (71) rotates due to the impact of the water, causing the mixing and stirring blades (74) to rotate to accelerate the mixing of ice water in the ice bath box (41). At the same time, the blades of the turbines (73) rotating inside the two adjacent water pumps (71) rotate in different directions. Therefore, the two adjacent mixing and stirring blades (74) rotate in different directions, further improving the mixing efficiency.
