Detailed Embodiments

[0028] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0029] See Figure 1 The schematic diagram of a preferred embodiment of an integrated automatic constant temperature water bath. In this embodiment, the main structure of the integrated automatic constant temperature water bath is a structural cabinet 4, which is formed by cold-rolled steel plate and undergoes surface plastic spraying treatment, ensuring the durability and anti-corrosion performance of the equipment; the structural cabinet 4 can be provided with a foot structure at the corner position of the bottom surface of the cabinet to prevent the fixed position and ensure the stability of the cabinet placement, or a traveling wheel with a braking structure can be provided at the corner position of the bottom surface of the cabinet to achieve the convenient movement of the equipment.

[0030] The top surface of the cabinet on one side of the perspective of the structural cabinet 4 is a functional area. The surface of the functional area is formed with a function cavity 14 and a water bath cavity arranged side by side. The function cavity 14 and the water bath cavity are sunken cavity structures arranged at the same height plane position of the structural cabinet. The function cavity wall 9 of the function cavity 14 and the water bath cavity wall 19 of the water bath cavity are both formed by stainless steel material, ensuring the use performance of the corresponding function cavity 14 and water bath cavity. At the same time, a polyurethane foam layer is formed on the outer side of the cavity walls of both to be used as an outer thermal insulation layer to reduce heat loss and effectively improve the energy efficiency of the equipment.

[0031] The water bath cavity is the main functional structure of the equipment. A heat equalizing layer 17 is formed at the lower inner side position of the water bath cavity wall 19. The heat equalizing layer 17 divides the entire water bath cavity into an upper water bath cavity 16 and a lower heating cavity 15. The water bath cavity 16 is a working space for performing water bath operations, while the heating cavity 15 is used to provide a heat medium for the water bath operation. In order to realize the heating of the heat medium in the heating cavity 15, a surface heating electric heating unit 18 is provided at the bottom surface of the cavity of the heating cavity 15.

[0032] In different embodiments, there are two ways for the heat equalizing layer 17 to process the water bath cavity:

[0033] In this embodiment, the heat equalizing layer 17 is a fixed frame with a flexible heat equalizing material spacer / diaphragm (such as a spacer / diaphragm formed by silicone rubber material) with deformation performance formed on the inner side of the frame. The heat equalizing layer 17 divides the water bath cavity 16 and the heating cavity 15 into independent chambers, enabling different heat conducting media to be filled in the two. Water is filled in the water bath cavity 16, while heat conducting oil is filled in the heating cavity 15. The heat conductivity coefficient of the heat conducting oil is higher than that of water, which helps to ensure the heating efficiency and temperature uniformity. The deformation space design of the heat equalizing layer 17 allows it to maintain good sealing performance and thermal strain resistance at different temperatures, thus avoiding the deformation and sealing defects caused by the medium mixing and thermal stress between the chambers.

[0034] In addition, a circulation pipeline 20 with a pumping device 21 is provided at the bottom and top of the water bath chamber 16 in this embodiment. When the size of the water bath chamber 16 is relatively large, the circulation pipeline 20 pumps the circulation at the bottom of the water bath chamber 16 to the upper part through the pumping device 21 to form a circulating flowing water bath environment with uniform temperature. This circulation design not only improves the temperature uniformity but also helps to reduce the phenomenon of local overheating, thereby further improving the accuracy of the experimental results.

[0035] In another embodiment, the heat dissipation and isolation layer 17 adopts a double-layer porous ceramic heat dissipation plate. The pore structure ensures the medium flow between the water bath chamber 16 and the heating chamber 15. This design can also achieve the heat exchange between the water bath chamber and the heating chamber and realize the uniform transfer of temperature. In order to reduce the influence of local temperature change in the heating chamber 15, the volume ratio of the water bath chamber 16 to the heating chamber 15 is designed to be 3:1 to 4:1 to ensure the temperature stability during the water bath process.

[0036] To further improve the accuracy of temperature control, a temperature sensor is provided on the inner wall of the water bath chamber 16. The temperature sensor can monitor the temperature change in the water bath chamber 16 in real time and transmit the data to the electronic control system for analysis and adjustment. The electronic control system ensures the temperature stability and accuracy during the water bath process by performing precise temperature feedback control on the electric heating unit 18 according to the set temperature parameters.

[0037] In this embodiment, the function of the functional chamber 14 is a preheating, heat preservation, and temporary storage space. A detachable water draining rack 10 is provided at the bottom of the functional chamber 14, which is convenient for users to clean the residual liquid in the chamber after the experiment. The bottom surface of the functional chamber 14 is an inclined surface 13, and is connected to the drain hole 11 at the bottom of the side wall of the structural cabinet 8 through a drain pipe at the bottom of the inclined surface. The combination of the inclined surface 13, the drain pipe, and the drain hole 11 is used to ensure that the water medium after draining can be discharged smoothly.

[0038] An electric control cooling element 22 and a closed cover structure (not marked) are also provided in the area of the functional chamber 14; the electric control cooling element 22 is a semiconductor refrigerator, which is arranged on the outer side of the wall 9 of the functional chamber, and can be controlled by an electronic control unit to realize the cooling or heating of the space inside the functional chamber 14 to meet the needs of preheating and heat preservation. The closed cover structure is an electronically controlled upper flip cover with a sealing structure, which is used to keep the functional chamber 14 warm in the closed state to reduce the energy consumption of the equipment.

[0039] In addition, in this embodiment, a component cavity is formed on the back side of the perspective of the structural cabinet 4. In this component cavity, in addition to the electronic control unit for realizing the corresponding functions of the water bath cavity and the functional cavity 14 in this embodiment, an electronically controlled lifting seat 2 is also provided. The electronically controlled lifting seat 2 includes four electronically controlled lifting rods, and the four electronically controlled lifting rods lift synchronously. At the top of the four electronically controlled lifting rods of the electronically controlled lifting seat 2, a top plate 1 is assembled. The size of the top plate 1 is the same as the surface size of the functional area, so as to be able to cover the top surfaces of the functional cavity 14 and the water bath cavity in the state where the electronically controlled lifting seat 2 descends (when covering the surface of the functional cavity 14, it covers the surface of the closed cover structure in the closed state); when the top plate 1 is lifted by the electronically controlled lifting seat 2, it is used for corresponding material taking and placing operations on the water bath cavity and the functional cavity 14.

[0040] In order to better realize the material taking and placing operations on the water bath cavity and the functional cavity 14 when the top plate 1 is lifted, a transfer rack assembly is provided on the lower surface of the corresponding top plate 1. The transfer rack assembly includes a set of slide seat guide rails 3 and an electronically controlled slide seat 5 arranged on the slide seat guide rails 3. The slide seat guide rails 3 are arranged along the length connection line of the water bath cavity and the functional cavity 14. Limit side stops 7 with travel switches are arranged at both ends of the slide seat guide rails 3, so that the electronically controlled slide seat 5 can be switched between the water bath cavity and the functional cavity 14 in an electrically driven manner. Electronically controlled fixing frames 6 are arranged on both sides of the lower part of the electronically controlled slide seat 5. The electronically controlled fixing frames 6 are used to fix the positions of the matching water bath container brackets 4. The corresponding water bath container brackets 4 can be adjusted or customized according to the shapes and sizes of different water bath containers.

[0041] In this embodiment, the electronically controlled fixing frame 6 adopts a magnetic or snap - type fixing structure, which is convenient for releasing the water bath container bracket 4 by electronic control after the water bath container bracket 4 moves to the corresponding position of the water bath cavity or the functional cavity 14, so that it can be stably placed on the fixed frame or the draining rack 10 of the corresponding heat - equalizing interlayer 17. In addition, a position sensor is equipped on the side of the electronically controlled fixing frame 6 to detect whether the water bath container bracket 4 is correctly installed.

[0042] In addition, an illumination and camera system is also integrated on the bottom surface of the top plate 1. The illumination system uses LED light sources, which are evenly distributed at the bottom of the top plate 1, providing sufficient light for the water bath cavity and the functional cavity 14, and is used to cooperate with the camera system to facilitate the user to observe the sample state in the state where the top plate 1 is covered.

[0043] In order to further improve the user experience, this embodiment also designs a human - machine interaction interface, which is integrated on the front side or the side of the structural cabinet 4. This interface uses a touch screen, intuitively displays various parameters of the device (such as temperature, time, working mode, etc.), and supports the user to set parameters, start / stop the device, view historical records, etc. by gently touching or swiping with fingers.

[0044] In other different embodiments, in order to further improve the practicability of the device, the functional cavities 14 provided on the structural cabinet body can also be two. When the functional cavities 14 are set to two, the two functional cavities 14 are respectively arranged on both sides of the water bath cavity.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
